[0037] It can be understood that by setting the loading plate 140 and the transfer plate 160, the loading plate 140 has a plurality of accommodating grooves 150, a plurality of camera modules 100 are respectively placed in the plurality of accommodating grooves 150, and the lens part 120 of the camera module 100 faces downward, the ACF 130 can be attached to the body 110 of the camera module 100, after the ACF 130 is attached, the transfer plate 160 can be stacked on the loading plate 140, the first supporting surface and the second supporting surface are attached, during the inspection work, the transfer plate 160 and the loading plate 140 can be flipped synchronously, the transfer plate 160 and the loading plate 140 are in an inverted state, the loading plate 140 is separated from the transfer plate 160, the camera module 100 is inverted on the second supporting surface, the lens part 120 of the camera module 100 faces upward, and the inspection work can be performed, so that the worker does not need to use tweezers to clamp the camera module 100, and the scratch defect caused by clamping on the camera module 100 is avoided, and the transfer plate 160 can be used to flip the camera module 100 in batches, and the inspection efficiency is greatly improved.
[0038] The turning tool for appearance inspection of the camera module comprises a positioning assembly, the number of the positioning assembly is matched with the number of the accommodating grooves 150, the positioning assembly comprises at least two positioning pins 170 and a positioning groove 180 matched with the positioning pin 170, the positioning pin 170 is arranged on the second supporting surface, and the positioning groove 180 is arranged on the first supporting surface, the loading plate 140 and the transfer plate 160 are inverted, the loading plate 140 is separated from the transfer plate 160, and the position of the body 110 is limited in the horizontal direction between the at least two positioning pins 170.
[0039] It can be understood that by arranging the positioning pin 170 and the positioning groove 180, the positioning pin 170 is provided with at least two, when the transfer plate 160 is stacked on the loading plate 140, the positioning pin 170 is inserted into the positioning groove 180, so that the body 110 of the camera module 100 is limited in the horizontal direction between the at least two positioning pins 170, the camera module 100 is not easy to be deviated when the loading plate 140 is separated from the transfer plate 160, after inspection, the position of the camera module 100 does not need to be adjusted, the loading plate 140 can be quickly stacked on the transfer plate 160, the transfer plate 160 and the loading plate 140 are flipped synchronously, the camera module 100 is reloaded into the accommodating groove 150 of the loading plate 140, and therefore, the inspection work efficiency is greatly improved.
[0040] Specifically, referring to Figure 4 , Figure 6 , and Figure 8 , the positioning assembly has four positioning pins 170, the four positioning pins 170 are arranged in a rectangular shape on the second supporting surface, the body 110 is accommodated between the four positioning pins 170, and the outer side of the accommodating groove 150 is provided with four positioning grooves 180 corresponding to the four positioning pins 170.
[0041] The body 110 of the camera module 100 can be square in shape. The four edges of the horizontal outer side of the body 110 are chamfered. The four positioning pins 170 respectively restrict the chamfer of the body 110, thereby preventing the position of the camera module 100 from shifting, which greatly facilitates the inspection operation. In addition, without adjusting the position of the camera module 100, the loading plate 140 can be quickly stacked on the transfer plate 160, so that the camera module 100 can be reinstalled into the receiving slot 150 of the loading plate 140.
[0042] In some embodiments of this utility model, reference is made to Figure 3 , Figure 5 and Figure 7 The positioning groove 180 is arranged in a right-angled triangle on the first support surface. The positioning groove 180 has a first inner sidewall 190 and a second inner sidewall 200. The first inner sidewall 190 and the second inner sidewall 200 are arranged vertically. The first inner sidewall 190 and the second inner sidewall 200 are used to limit the horizontal position of the positioning pin 170.
[0043] By making the positioning groove 180 a right-angled triangle, the space of the positioning groove 180 is made larger, the positioning pin 170 is easier to insert into the positioning groove 180, the loading plate 140 is easier to stack on the transfer plate 160, and the first inner sidewall 190 and the second inner sidewall 200 are used to limit the horizontal position of the positioning pin 170, so that the positioning pin 170 can limit the position of the body 110 of the camera module 100.
[0044] In a further embodiment of the present invention, the first inner sidewall 190 and the second inner sidewall 200 are disposed away from the positioning groove 180. Therefore, when the positioning groove 180 is arranged along the outer side of the receiving groove 150, it occupies a smaller area of the first support surface.
[0045] In some embodiments of this utility model, reference is made to Figure 6 The positioning component has a first clearance groove 230, and at least two positioning pins 170 are provided in the first clearance groove 230. The first clearance groove 230 is arranged along the outer shape of the body 110. Therefore, the first clearance groove 230 can accommodate the body 110 of the camera module 100. Furthermore, the positioning pins 170 are provided in the first clearance groove 230, which helps to reduce the height of the positioning pins 170.
[0046] In a further embodiment of the present invention, the positioning component has a second clearance groove 240, which is the same as the first clearance groove 230. The second clearance groove 240 is used to accommodate the ACF130. Therefore, when the transfer plate 160 is stacked on the loading plate 140, the second clearance groove 240 can avoid the ACF130, thus preventing the transfer plate 160 from damaging the ACF130.
[0047] In some embodiments of this utility model, reference is made to Figure 2 The end of the positioning pin 170 has a conical portion 250, which is used to guide the positioning pin 170 into the positioning groove 180, thereby allowing the positioning pin 170 to be smoothly inserted into the positioning groove 180.
[0048] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The transfer plate 160 is provided with a guide post 260, and the loading plate 140 is provided with a guide hole 270, which accommodates the guide post 260.
[0049] It should be noted that the length of the guide post 260 is greater than the length of the positioning pin 170. When the transfer plate 160 is stacked on the loading plate 140, the guide post 260 is inserted into the guide hole 270 to avoid damage to the camera module 100 due to inaccurate insertion of the positioning pin 170.
[0050] In some embodiments of this utility model, reference is made to Figure 1 The loading plate 140 has a clearance opening 280 on its horizontal side. Therefore, after the loading plate 140 and the transfer plate 160 are flipped and inverted, the operator can take the loading plate 140 through the clearance opening 280 and detach the loading plate 140 from the transfer plate 160, which greatly facilitates the detachment of the loading plate 140.
[0051] In the description of this specification, the references to terms such as "an embodiment, some embodiments, illustrative embodiments, example, specific example, or examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
