[0010] The suction and pressing component is used to automatically suck up and press the dial of the watch for installation.

[0011] A further improvement is that the inner wall of the fixed clamping plate is provided with a mounting notch, and a rubber clamping pad is connected in the mounting notch via a fixing screw.

[0012] A further improvement is that the suction and pressing assembly includes a lifting seat arranged on the side of the sliding seat, a suction cup mounting seat arranged on the side of the lifting seat, a negative pressure vacuum tube arranged on the suction cup mounting seat, a silicone suction cup arranged on the bottom surface of the negative pressure vacuum tube and a vacuum generator arranged on the top surface of the sliding seat, the output end of the vacuum generator is provided with a rubber tube connected to the negative pressure vacuum tube, and an electromagnetic control valve is provided at the connecting end of the negative pressure vacuum tube and the rubber tube.

The positioning prompt component includes a sliding rod arranged in the groove, a spring touch switch arranged on the side of the sliding rod located on the movable seat, a prompt light arranged on the base and connected to the spring touch switch, and an adjusting cylinder arranged on the outer side of the assembly base, the rod end of the adjusting cylinder passes through the movable seat and is connected to the side of the sliding rod.

[0015] A further improvement is that the pair of fixing clamps have the same size and are both arc-shaped.

[0016] A further improvement is that a rubber pressing sheet is connected to the upper end of the inner wall surface of each rubber clamping pad, and the rubber pressing sheet and the rubber clamping pad are integrated, and the curvature is the same as the curvature of the inner wall surface of the rubber clamping pad.

[0017] A further improvement is that a ball screw is rotatably arranged in the port of the base, a limit rod is respectively arranged in the upper and lower positions of the ball screw in the port of the base, a thread groove is penetrated through the middle of the sliding seat, a through groove is respectively penetrated through the upper and lower positions of the thread groove, the sliding seat is threadedly sleeved on the ball screw and on the two limit rods, and the ball screw is driven by a servo motor externally arranged on the side of the base.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

At this time, the electric lifting cylinder is started, driving the adjustment lifting seat to descend, so that the silicone suction cup can accurately contact and fit the dial. Subsequently, the vacuum generator is activated to generate a strong adsorption force, and at the same time the electromagnetic control valve is opened to ensure that the dial is firmly adsorbed on the silicone suction cup. After that, the ball screw rotates in the opposite direction to smoothly bring the assembly back to the initial position, without the need for manual insertion, to avoid damage to the outer wall of the dial due to incorrect operation.

[0022] (4) The present invention drives the adjustment lifting seat to slowly descend again through the electric lifting cylinder, and accurately places the dial carried by the silicone suction cup on the corresponding position of the dial or movement. During this descending process, the silicone suction cup not only provides stable support, but also effectively avoids any potential damage to the dial caused by improper force control through its soft and uniform pressing characteristics, thereby ensuring the assembly accuracy while significantly improving the overall assembly efficiency and the quality of the finished product.

[0039] Specifically, the inner wall of the fixed clamping plate 21 is provided with a mounting notch 211, and a rubber clamping pad 212 is connected to the mounting notch 211 through a fixing screw. The size of a pair of fixed clamping plates 21 is the same, and both are arc-shaped. The upper end of the inner wall surface of the rubber clamping pad 212 is connected with a rubber pressing sheet 213. The rubber pressing sheet 213 and the rubber clamping pad 212 are integrated, and the curvature is the same as the curvature of the inner wall surface of the rubber clamping pad 212.

[0041] Specifically, a pair of guide rods 331 are provided in the side port of the sliding seat 33, and the top surface is connected to the electric lifting cylinder 32.

[0043] like Figures 1 to 6 As shown, in this embodiment, before the implementation of the application document, a pushing cylinder 11 is arranged on the outer side of the assembly base 1, and the rod end of the pushing cylinder 11 penetrates into the side of the assembly base 1 and the moving base 2 for connection, so as to automatically push the clock dial on the moving base 2; a group of pressure sensors are arranged in the moving base 2 for monitoring the pressing pressure; a spring touch switch 52 is preset on the limit rod 34, and the spring touch switch 52 is connected to the prompt light 53 on the base 3 for prompting; the speed of the servo motor is set in advance; a PLC control cabinet is also configured, and a main control board is arranged in the control cabinet, and the main control board is pre-implanted with a control system for controlling the suction and pressing component 4, the electric lifting cylinder 32, the servo motor, the pushing cylinder 11, and processing and displaying the pressure signal of the pressure sensor.

[0044] It should be noted that the vacuum generator 45 and the electromagnetic control valve 46, the electric lifting cylinder 32, the servo motor, the push cylinder 11 and the pressure sensor in the suction and pressing assembly 4 are commercially available products of the prior art, and the working principle has been disclosed. Before implementation, select the corresponding product signal for installation. In addition, the application document only improves the shortcomings of the existing traditional manual pressing method of assembling watches, which is difficult to ensure the uniformity of the pressing force and is prone to damage to the dial due to improper force during the assembly process, thereby affecting the overall assembly efficiency and the quality of the finished product, and does not involve other aspects; the working principle of this automatic assembly device for watch production is introduced as follows:

[0045] During installation and use, the on-site assembler selects a rubber clamping pad 212 of a suitable size to be installed on the inner wall of the fixed clamping plate 21 according to the size of the clock to be assembled, and then drives the slide bar 51 to move in the groove 12 by starting the adjustment cylinder 54 to adjust the position of the spring touch switch 52;

[0046] After adjustment, the watch dial to be assembled is precisely placed between a pair of specially made fixed clamps 21. Then, the stepper motor is started, which drives the double-headed screw 241 to rotate, and the two sections of threads on the screw with opposite directions are used to push the pair of sliding members 22 and the fixed clamps 21 to move toward each other until they tightly clamp the dial to achieve a stable fixation. During this process, the rubber pressing sheet 213 will gently and evenly press on the dial, effectively preventing any vertical displacement caused by external vibration, and ensuring the stability and safety of the fixing process.

[0047] After the fixation is completed, the push cylinder 11 is started to push the moving seat 2 and the clock dial fixed thereon to move along the preset path. When the side of the moving seat 2 touches the spring touch switch 52, this signal will immediately trigger the control system, light up the prompt light 53, and clearly indicate the current position, without the need for tedious manual debugging or repeated confirmation, which greatly simplifies the positioning process and improves assembly efficiency.

[0048] Then, the servo motor on the starter base 3 starts working, driving the ball screw 31 to rotate at a constant speed, driving the sliding seat 33 and the suction and pressing assembly 4 thereon to move in a predetermined direction to a preset distance. At this time, the electric lifting cylinder 32 starts, driving the adjustment lifting seat 41 to descend, so that the silicone suction cup 44 accurately contacts and fits on the dial. Subsequently, the vacuum generator 45 is activated to generate a strong suction force, and the electromagnetic control valve 46 is opened to ensure that the dial is firmly adsorbed on the silicone suction cup 44. After that, the ball screw 31 rotates in the opposite direction to smoothly bring the assembly back to the initial position.

[0049] Then the electric lifting cylinder 32 drives the adjusting lifting seat 41 to slowly descend again, and accurately places the dial carried by the silicone suction cup 44 on the corresponding position of the dial or movement. During this descending process, the silicone suction cup 44 not only provides stable support, but also effectively avoids any potential damage to the dial caused by improper force control through its soft and uniform pressing characteristics, thereby ensuring the assembly accuracy while significantly improving the overall assembly efficiency and the quality of the finished product.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it.
