A watch case automatic assembly and pressing mechanism

Abstract

The invention discloses an automatic assembling and pressing mechanism for a watch shell, which comprises a feeding machine and a material distributing machine, wherein the feeding machine and the material distributing mechanism are equipped with an assembling machine therebetween capable of automatically combining and crimping an incoming shell cover and bottom shell, the table top of the assembling machine is sequentially equipped with a shell carrying device, a dust collector, an oil dispenser, a turner and a shell transferring device in an independent material flow direction of the shell cover, the shell carrying device positions and directionally conveys a shell cover supplied by the feeding machine, the dust collector removes the dust on the shell cover, the oil dispenser dispenses oil on the shell cover, the turner turns the shell cover so as to enable the back of the shell cover to face downward, and the shell transferring device transfers the shell cover and crimps the shell cover on the bottom shell; and a movement carrying device and a clamping and pressing device are installed in an overlapped material flow direction of the bottom shell and the shell cover, the shell transferring device crimps the shell cover on the bottom shell conveyed by the material distributing machine to the movement carrying device, and then a pressing plate on the clamping and pressing device presses downward so as to enable the shell cover to be pressed on the bottom shell in place. The automatic assembling and pressing mechanism for the watch shell is automated in the whole process andhigh in assembly effect, greatly reduces the assembly cost of watches and improves the yield of watch movements.

Description

technical field [0001] The invention relates to automatic assembly equipment for watch production, in particular to an automatic assembly and pressing mechanism for watch shells. Background technique [0002] The clock movement includes a clock bottom case, various parts assembled in the clock bottom case and a watch case cover connected with the clock bottom case. At present, watch manufacturers still use manual assembly of the clock movement. The clock bottom case and the clock The problems of manual assembly of the case cover are as follows: ① Low efficiency of manual assembly: the structural design of the bottom case and the case cover of the watch is fine. During manual assembly, it is necessary to accurately align the bottom case and the case The watch case cover can be pressed and buckled on the watch bottom case without shifting the various parts in the bottom case of the watch. This requires workers to concentrate on the operation, and the workers are prone to fatig...

[0002] The clock movement includes a clock bottom case, various parts assembled in the clock bottom case and a watch case cover connected with the clock bottom case. At present, watch manufacturers still use manual assembly of the clock movement. The clock bottom case and the clock The problems of manual assembly of the case cover are as follows: ① Low efficiency of manual assembly: the structural design of the bottom case and the case cover of the watch is fine. During manual assembly, it is necessary to accurately align the bottom case and the case The watch case cover can be pressed and buckled on the watch bottom case without shifting the various parts in the bottom case of the watch. This requires workers to concentrate on the operation, and the workers are prone to fatigue. The production cost of the core is too high; ②The cleanliness of the manual assembly of the watch case cover is low: the watch case cover needs to be dust-removed and cleaned before it is assembled to the bottom case of the watch, so as to avoid dust or debris in the watch case cover that affects the precise operation of the watch movement. crumbs, etc., while laborers need to hold the watch case cover in one hand and vacuum cleaner in the other hand to absorb dust or debris; the oil on the hands of workers or the dust or debris in the exhaled gas will adhere to the watch case cover, which cannot be completely removed, which will affect The timing accuracy of the watch movement; ③The defective products of the manual assembly of the watch movement are high: a number of shaft holes are formed and distributed in the watch case cover, and some of these shaft holes are used to fit with the gear shaft assembled in the bottom case of the watch. Some are used for the docking and positioning of the watch case cover and the watch bottom case. If the manual alignment is not accurate and the watch case cover and the watch bottom case are forcibly butted and pressed together, if it is not smooth and jamming occurs, it will cause the machine Damage to the transmission parts or shaft holes inside the movement will greatly reduce the timing accuracy of the watch movement, and may even cause the entire watch movement to be scrapped
