[0023] The specific workflow is as follows: first, the mounting frame 2 is precisely positioned on the sliding table 1 by the fine positioning mechanism, ensuring that each mounting seat 31 is aligned with the through hole on the sealing plate 3, then the lens barrel is placed into the mounting seat 31 through the material placing hole 400 on the material clamping seat 4, the electric cylinder 51 drives the lifting plate 5 to rise, the connecting rod 52 descends accordingly, the top block 521 comes into contact with the inclined block at the lower part of the swing lever 32, forcing the swing lever 32 to open outward, and the clamping block 321 also opens, allowing the lens barrel to be smoothly placed into, after the lens barrel is completely placed in, the electric cylinder 51 drives the lifting plate 5 to descend, the top block 521 separates from the inclined block, the swing lever 32 resets under the action of the spring 322, the clamping block 321 closes and tightens the lens barrel, ensuring that the lens barrel does not loosen during assembly.
[0024] As shown in Figure 1 , Figure 2 and Figure 5 , the fine positioning mechanism includes transmission member one 8, guide rod 81, transmission member two 82 and sliding block 83, the sliding table 1 has transmission member one 8 on both left and right sides of the front part, and transmission member two 82 on both left and right sides of the right part, both transmission member one 8 and transmission member two 82 are composed of a transmission screw and a positioning motor, both transmission member one 8 and transmission member two 82 are equipped with transmission seats on the screw, the mounting frame 2 is equipped with guide rod 81 on both left and right sides, both left and right guide rods 81 pass through the transmission seats of the same side transmission member one 8, the mounting frame 2 is slidably connected with the transmission seats of the two transmission member one 8 through the guide rod 81, the screw rotation of the transmission seat one 8 drives the mounting frame 2 to move forward and backward in the sliding table 1, the mounting frame 2 is equipped with sliding block 83 on both front and back sides, both front and back sliding blocks 83 are slidably connected with the transmission seats of the same side transmission member two 82, the mounting frame 2 is slidably connected with the transmission seats of the two transmission member two 82 through the sliding block 83, the screw rotation of the transmission seat two 82 drives the mounting frame 2 to move left and right in the sliding table 1, the setting of the guide rod 81 and the sliding block 83 ensures that the mounting frame 2 can move in any position in the plane left and right or forward and backward at the same time or independently, for example, when the transmission member one 8 works, the mounting frame 2 moves forward and backward, at this time, to avoid the moving force acting on the transmission member two 82 during transmission, the sliding block on the transmission member two can offset this moving force.
[0025] The positioning motor of the transmission member one 8 and the transmission member two 82 drives the transmission screw to rotate, the transmission seat on the screw moves along the direction of the screw, drives the mounting frame 2 to move forward and backward and left and right in the sliding table 1 through the guide rod 81, realizes the precise positioning of the mounting frame 2 in the forward and backward direction, realizes the precise positioning of the mounting frame 2 in the left and right direction, in this way, the mounting frame 2 can realize accurate adjustment in multiple directions in the sliding table 1, ensuring that it can be quickly positioned in cooperation with the assembly device, thereby ensuring the accurate placement and assembly of the lens barrel.
[0026] The design of the fine positioning mechanism not only improves the positioning accuracy of the mounting frame 2, but also enhances the stability and reliability of the entire tooling system. In actual production, through the accurate control of the fine positioning mechanism, the assembly errors caused by position deviation can be significantly reduced, and the product yield and production efficiency can be improved. In addition, since the transmission member 1 8 and the transmission member 2 82 are both driven by the positioning motor, the operation is simple and fast, and the tooling can quickly adapt to different sizes and models of lens barrels, further improving the versatility and flexibility of the tooling.
[0027] In addition, as shown in Figure 1 and Figure 6 , the sealing plate 3 is additionally provided with a pair of light emitting diodes 7, a signal module 6 and a pilot lamp 61. At least one set of light emitting diodes 7 is arranged around the clamping hole of the clamping seat 4. The signal module 6 is arranged on the clamping seat 4 and is connected with the light emitting diodes 7 on the same clamping seat 4. The pilot lamp 61 is arranged on the signal module 6. By arranging light emitting diodes on the clamping seat, the fixing state of the lens in the clamping seat can be monitored in real time. At the same time, the signal module 6 can feed back signals in real time, so as to avoid the situation that the lens is skewed and still assembled.
[0028] Specifically, when the lens barrel is placed into the mounting seat 31 through the discharging hole 400 on the clamping seat 4, the light emitting diodes 7 can detect whether there is a lens barrel in the clamping seat 4 and whether the lens barrel is correctly placed. The light emitting diodes 7 are composed of a transmitter and a receiver. When the lens barrel is correctly placed, the light path of the light emitting diodes 7 is blocked by the lens barrel. The receiver detects the signal that the light path is blocked and transmits the signal to the signal module 6. After receiving the signal, the signal module 6 controls the pilot lamp 61 to light up, indicating that the lens barrel has been correctly placed and the next operation can be performed.
[0029] If the lens barrel is not placed correctly or is skewed, the light path of the light emitting diodes 7 will not be completely blocked. The receiver detects the signal that the light path is not completely blocked and transmits the signal to the signal module 6. After receiving the abnormal signal, the signal module 6 controls the pilot lamp 61 to flash or display a specific color, prompting the operator that the lens barrel is not placed correctly and needs to be adjusted. At this time, the system can pause the subsequent assembly steps until the lens barrel is correctly placed, so as to avoid assembly errors and product quality problems caused by lens skew.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
