The workbench 1 is further provided with a transfer station 17, a third carrying module 16, a discharging station 18 and a defective product track 19, the second carrying module 15 is used for placing the assembled camera module and mainboard on the transfer station 17, and the third carrying module 16 is used for selecting to place the assembled camera module and mainboard on the discharging station 18 or the defective product track 19 according to whether the assembly is wrong.

[0029] With reference to Figure 3 , the carrying mechanism 3 comprises a base 31, a carrying motor 34 and a carrying cylinder 33, the base 31 is arranged on the workbench 1 at one side of the mechanical arm 8 and the material bin 9, the carrying motor 34 is fixedly installed on the base 31, the carrying cylinder 33 is installed on the output end of the carrying motor 34, and the output end of the carrying cylinder 33 is connected with a carrying clamp jaw 32. After the mechanical arm 8 takes out the camera module from the material bin 9, the camera module is placed on the carrying clamp jaw 32 controlled by the carrying cylinder 33 to be clamped, and then the carrying motor 34 is started to make the carrying clamp jaw 32 rotate by ninety degrees, so that the camera module is placed on the positioning mechanism 6, and the film on the camera module is arranged upwards.

[0030] With reference to Figure 3 andFigure 4 The positioning mechanism 6 comprises a positioning frame 61, a positioning platform 62 and a positioning cylinder 63, which are combined Figure 1 The positioning frame 61 is fixedly installed between the carrying mechanism 3 and the film tearing mechanism 2, the positioning platform 62 is fixedly installed on the top surface of the positioning frame 61, and the positioning cylinder 63 is installed on the side wall of the positioning platform 62.

After the carrying mechanism 3 places the camera module on the positioning platform 62, the first positioning block 64 and the second positioning block 65 are controlled to clamp the camera module, so as to complete the positioning.

[0031] Referring to Figure 1 and Figure 3 The film tearing mechanism 2 comprises a horizontal movement module 21, a lifting movement module 22, a driving cylinder 23 and a discharge hopper 29, which are combined Figure 4 The discharge hopper 29 is fixedly installed between the horizontal movement module 21 and the positioning frame 61, the lifting movement module 22 is installed on the horizontal movement module 21, and the driving cylinder 23 is installed on the lifting movement module 22. The output end of the driving cylinder 23 is connected with the first clamping jaw 24. The film tearing mechanism 2 further comprises a fixed plate 25, which is vertically arranged on one side of the discharge hopper 29. The top end of the fixed plate 25 is provided with an electrostatic eliminator 26 and a photoelectric sensor 27, and the bottom end of the discharge hopper 29 is connected with a vacuum generator 28. In the implementation, after the camera module is fixed on the positioning platform 62, the horizontal movement module 21 is controlled to drive the first clamping jaw 24 to move to the camera module, and then the driving cylinder 23 is controlled to make the first clamping jaw 24 clamp the film. Subsequently, the lifting movement module 22 is started to drive the first clamping jaw 24 to move upward to complete the film tearing operation. Subsequently, whether the film tearing is completed is detected by the photoelectric sensor 27, that is, whether the film exists on the first clamping jaw 24 is detected. If the film exists, the vacuum generator 28 and the electrostatic eliminator 26 are started. The electrostatic eliminator 26 blows plasma wind, which cooperates with the vacuum adsorption to make the torn film be recycled by the discharge hopper 29 as much as possible. Through the cooperation of the horizontal movement module 21, the lifting movement module 22 and the driving cylinder 23, the accurate clamping and stable tearing of the protective film of the camera module can be realized, and the controllability and repeat precision of the film tearing operation are ensured. With the real-time detection of the tearing result by the photoelectric sensor 27, whether there is residual film can be identified in time, and the defective assembly can be prevented from flowing into the subsequent process. At the same time, the electrostatic eliminator 26 and the vacuum generator 28 are used in cooperation, so that the torn film can quickly separate from the clamping jaw after being peeled off and be effectively recycled by the discharge hopper 29. Not only the secondary pollution risk caused by the floating of the film is reduced, but also the cleanliness of the working environment and the reliability of the production are improved.

[0032] Referring to Figure 1 and Figure 2The first mounting mechanism 4 comprises a first screw gun 41, a first camera 42 and a first pressing cylinder 43. The first screw gun 41 is arranged on the periphery of the electric turntable 11. The first camera 42 is arranged on the first screw gun 41. The first pressing cylinder 43 is arranged on one side of the first screw gun 41. The output end of the first pressing cylinder 43 is connected with a first pressing plate 44, which is used to press the main board. The second mounting mechanism 5 comprises a second screw gun 51, a second camera 52 and a second pressing cylinder 53. The second screw gun 51 is arranged on the periphery of the electric turntable 11. The second camera 52 is arranged on the second screw gun 51. The second pressing cylinder 53 is arranged on one side of the second screw gun 51. The output end of the second pressing cylinder 53 is connected with a second pressing plate 54, which is used to press the main board. Since the first mounting mechanism 4 and the second mounting mechanism 5 are arranged in the same way and operate in the same way, only the first mounting mechanism 4 will be described below. In the implementation, the first screw gun 41 can move along the x, y and z axes. When the assembly station 14 rotates to the first mounting mechanism 4, the first pressing cylinder 43 is first started to drive the first pressing plate 44 to press the main board and the camera module tightly, so that the screwing operation is not prone to looseness. Then, the first camera 42 is used to take pictures to calibrate the position. The first screw gun 41 is controlled to move and perform screw assembly operation according to the calibration of the first camera 42. After assembly, the camera is used to take pictures to detect whether the screw is assembled well. If there is a problem in assembly, the defective product track 19 needs to be sent in subsequently. The pressing plate driven by the pressing cylinder can reliably press the main board and the camera module before screwing, which can effectively avoid assembly deviation caused by part looseness during screw tightening. Combined with the picture calibration and detection of the camera before and after screwing, not only the accurate correction of the screw position can be realized to ensure the accuracy of the screwing action, but also the screw tightening quality can be judged in real time after assembly to identify assembly defects in time and guide to the defective product track 19, thereby ensuring the stability, consistency and product quality of the product assembly process.

[0033] In summary, the device as a whole is based on the workbench 1, and the material bin 9, the mechanical arm 8, the carrying mechanism 3, the positioning mechanism 6 and the film tearing mechanism 2 are arranged on one side of the workbench 1, and the electric turntable 11 and a plurality of workstations distributed in the circumferential direction thereof are arranged on the other side. Specifically, the mechanical arm 8 is used to take out the camera module with the protective film from the material bin 9, and cooperate with the carrying mechanism 3 to place it on the positioning mechanism 6; after the positioning mechanism 6 clamps and positions the camera module, the film tearing mechanism 2 can accurately clamp and stably remove the protective film on the surface of the camera module, and at the same time, through the cooperation of sensing detection and static elimination, the film is effectively recycled, and residual film is avoided from entering the subsequent process. In the sequence after the film tearing is completed, the mechanical arm 8 moves the camera module to the assembly workstation 14 on the electric turntable 11, and the electric turntable 11 is sequentially rotated to the mainboard feeding workstation 13, the first mounting mechanism 4 and the second mounting mechanism 5, wherein the mainboard is placed above the camera module by the carrying module, the installation of the screw is ensured by the pressing plate pressed to stably position the camera module and the mainboard, and combined with the camera alignment and detection, the screw gun can complete the accurate tightening of the multi-point screw and the real-time determination of the tightening quality. Finally, the assembled parts are sent to the transfer workstation 17 through the turntable, and selected to enter the discharging workstation 18 or the defective product track 19 through the carrying module, so as to realize the diversion of good products and defective products.

[0034] Through the cooperation of the above mechanisms, the full-process automatic processing of the camera module from material taking, positioning, film tearing, assembly to screw fastening and detection is realized, and the problem that the film tearing, positioning and screw fixing operations are generally completed by manual operation in the prior art is solved. The manual method not only has low efficiency, but also is easy to produce operation errors, which leads to inaccurate positioning of the camera module, poor screw fastening and residual film, thereby causing unstable and inconsistent product quality. Through the introduction of automatic structure design and visual detection, the assembly efficiency can be significantly improved, the stability and repeatability of the operation can be ensured, and the product consistency and overall assembly quality can be effectively improved.

[0035] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
