The bottom shell is butted with the watchcase to form a watch shell.
Specifically, as shown in fig. 3, after the watch case to be bonded is placed in the profiling groove 301, the first pressure-retaining block 302 is pressed down on the upper side of the watch case forming the watch case, so that the uniqueness of the position of the watch case in the profiling groove 301 is ensured, a positioning foundation is provided for the suction cup assembly 6 to suck and grasp the watch case, and the multi-axis driving module 7 is ensured to drive the suction cup assembly 6 to accurately suck and grasp the watch case. The multi-shaft driving module 7 drives the watch case to act through the sucker assembly 6, and under the condition that a flat cable between the bottom shell and the watch case is in a normal state, the edge on the bottom shell is sequentially exposed under the dispensing assembly 2. The dispensing assembly 2 can finish the dispensing operation of the whole edge on the bottom shell through multiple actions.
The multi-shaft driving module 7 can also drive the sucking disc assembly 6 to adhere the watchcase and the bottom shell with glue at the edge, and then the watchcase is pressed down on the watchcase through the first pressure-keeping block 302, so that the watchcase and the bottom shell after being adhered are in a pressure-keeping state before being transferred. And the pressure maintaining carrying clamp 5 is propped against the top of the watch case through the second pressure maintaining block 501 in the process of grabbing and transferring the watch case, so that the first pressure maintaining block 302 is still in a pressed state after being removed from the watch case until the bottom frame supporting block 502 on the pressure maintaining carrying clamp 5 is buckled on the bottom case, the profiling groove 301 on the feeding station 3 is removed, and the second pressure maintaining block 501 is matched to press the watch case. During this dynamic process, the bonded together case and bottom are always under pressure. After the watchcase and the bottom shell are bonded together by the cooperation of the pressure maintaining jig 4, the pressure maintaining state can be maintained for a long time, the production efficiency is improved, the bonding strength of the watchcase and the bottom shell can be ensured, and the quality of a product is improved.
Specifically, as shown in fig. 3, the suction cup assembly 6 is provided with a suction cup capable of being adsorbed on the watch case, and when the suction cup is adsorbed on the watch case, the multi-axis driving module 7 drives the suction cup assembly 6 to act, so that the watch case can be driven to horizontally move, vertically lift and turn. Preferably, the multi-axis driving module 7 in the present embodiment can drive the suction cup assembly 6 to move along the X-direction, the Y-direction, and the Z-direction, and rotate with the X-direction and/or the Y-direction as the rotation axes, and the X-direction, the Y-direction, and the Z-direction are perpendicular to each other and correspond to the X-axis, the Y-axis, and the Z-axis in the spatial coordinate system, respectively. And the pressure maintaining carrying clamp 5 can be moved back and forth between the feeding station 3 and the pressure maintaining clamp 4 and can be driven by a plurality of driving modules corresponding to the X axis, the Y axis and the Z axis, and the driving modules can select standard driving parts such as a servo sliding table, a screw sliding table and the like so as to ensure the accuracy and stability of the displacement of the pressure maintaining carrying clamp 5.
