Compression deformation occurs; then, the distance between the abutting part of the acquisition part 7 and the sensor 19 is measured by the sensor 19 to obtain the actual measurement value, and the second control module receives the actual measurement value sent by the sensor 19 and the actual measurement value. Corresponding signal and judging whether the actual measured value is the same as the preset value, then: if the two are the same, it means that the uppermost connecting piece 4 is lifted to the preset position, and the second control module controls the power member 18 to remain stationary, so that The suction member 11 of the transfer mechanism 1 can smoothly absorb the uppermost connecting piece 4; if the actual measured value is greater than the preset value, it indicates that the uppermost connecting piece 4 is higher than the preset position, and the second control module controls the power member 18 Drive the lifting member 17 to move down until the uppermost connecting piece 4 drops to the preset position, so that the suction member 11 of the transfer mechanism 1 can smoothly absorb the uppermost connecting piece 4; if the actual measured value is less than the preset value value, indicating that the uppermost connecting piece 4 is lower than the preset position, and the second control module drives the lifting member 17 to rise by controlling the power member 18 until the uppermost connecting piece 4 rises to the preset position, so as to facilitate the transfer The suction member 11 of the mechanism 1 can smoothly absorb the uppermost connecting piece 4 . It can be understood that, taking the lifting member 17 as an example of a spring, when the recovery deformation of the spring is less than the thickness of a single connecting piece, the plurality of connecting pieces are transported by the transfer mechanism one by one from top to bottom, and each time the storage rack decreases by one. The connecting piece and the spring release a certain elastic potential energy and restore a certain amount of deformation accordingly. It is worth mentioning that, in order to enable the uppermost connecting piece to move and stay at a predetermined position for the transfer mechanism to acquire, the preset value set by the second control module should gradually increase as the number of connecting pieces decreases. That is, every time a connecting piece is reduced on the storage rack, the preset value increases the thickness of one connecting piece accordingly (the connecting piece is set to an equal-thickness structure), and accordingly, the spring restores a certain amount of deformation, and the spring is in the power element. Under the driving action, the remaining distance is raised, so that the plurality of connecting pieces can rise simultaneously by a distance equal to the thickness of a single connecting piece.

The above descriptions are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the within the scope of protection of the present invention.
