Abstract: The present disclosure discloses a method and device for forming a groove on an electrode plate. The method for forming a groove on an electrode plate includes: thinning an active material layer by a laser method, where the active material layer is located in a to-be-grooved area of the electrode plate; and removing the thinned active material layer by a physical removal method to form an accommodating groove that exposes the current collector layer. By adopting a combination of the laser method and the physical removal method, the present disclosure, the present disclosure, on the one hand, can quickly remove the active material layer in the to-be-grooved area, and on the other hand, can avoid damaging the current collector layer. This ensures the processing precision, speeds up the production and improves the product yield.

Abstract: A rapidly assembled sofa includes left and right armrests, a back board and a seat board. The upper portion on the lateral surface of the back board is connected with the armrests in a slider mode, the lower portion on the lateral surface of the back board is connected with the armrests in a latch pin mode, and the seat board is flexibly fastened to the armrests. The rapidly assembled sofa is advantageous in that a connection mode without any bolt is achieved, and the stability in the case of utilizing a bolt for connection can be achieved; the assembling becomes much easier, more convenient and faster, and both time and energy are saved; the assembling operation can be accomplished by a single person, which is especially suitable for women customers; and the contour is clean and artistic since the connection structure is hidden after assembled.

Abstract: An optical transceiver module includes a housing comprising a first end and a second end, an electrical interface associated with the first end and an optical interface associated with the second end. The electrical interface is adapted to be locked into a receiving cage. The optical interface is adapted to be connected with one or more optical transceiver components. The optical transceiver module includes a locating mechanism that restrains the one or more optical transceiver components. The optical transceiver module also includes a locking mechanism that can lock the optical transceiver module to a receiving cage. The optical transceiver module further includes an automatic-restoring unlocking mechanism comprising a sliding plate, an unlocking lever, and a restoration spring, wherein the automatic restoring unlocking mechanism automatically restores the sliding plate to the normal position after the optical transceiver module is unlocked from the receiving cage.
