[0022] Figure 1 and Figure 2This is a structural schematic diagram of product A in this embodiment. Figure 3 This is an exploded view of product A in this embodiment. Figures 1-3 As shown, product A is a camera module, which includes a cover A4 and a base. The base includes a flexible circuit board A6, a lens A5 disposed on the flexible circuit board A6, and a connection terminal A2. The connection terminal A2 is used for communication connection between the camera module and electronic devices.

[0023] Specifically, the cover A4 includes a housing A41 and a side plate A42 extending laterally toward the housing A41. The housing A41 has a through hole for accommodating a lens A5. The flexible circuit board A6 includes a first plate A61 and a second plate A62. A photosensitive chip and a lens A5 corresponding to the photosensitive chip are disposed on the top of the first plate A61. The second plate A62 extends from one side of the first plate A61, and a connecting end A2 is disposed on the side of the second plate A62 away from the first plate A61. A QR code A1 is also disposed on the bottom of the second plate A62. An adhesive is also disposed on the base. The adhesive includes a first adhesive layer A31, a second adhesive layer A32, and a third adhesive layer A33, so that the base is bonded to the cover A4.

[0024] Figure 4 and Figure 5 This is a schematic diagram of the assembly equipment in this embodiment. Figure 6 This is an exploded view of the support part 1, the positioning part 2, and the product A in this embodiment. Figure 7 This is an exploded view of the support section 1 in this embodiment. Figure 8 This is a partially enlarged schematic diagram of the positioning fixture in this embodiment.

[0025] In some implementations, such as Figures 4-5 As shown, the assembly equipment includes a positioning fixture, a conveying unit 4, a baking unit 5, a mounting unit 6, a lifting unit 7, and an ejection unit (not shown in the figure). Further refer to... Figures 6-8 As shown, the positioning fixture includes a support part 1 and a positioning part 2. The support part 1 includes a carrier tray 11 and an adhesive pad 12. One side of the adhesive pad 12 is attached to the carrier tray 11, and the other side has a plurality of adhesive areas 121 spaced apart. The plurality of adhesive areas 121 are distributed in a rectangular array. The positioning part 2 has a support surface 21. The support surface 21 has a plurality of suction holes 22, and the side of the carrier tray 11 facing away from the adhesive pad 12 is disposed on the support surface 21 and is disposed opposite to the plurality of suction holes 22. In this embodiment, the plurality of adhesive areas 121 can be used to respectively mount product A, and the bottom of product A is attached to the adhesive area 121 to prevent product A from deforming during assembly.

[0026] Figure 9 yes Figure 1 Schematic diagram of cross-section at point BB. Figure 10 yes Figure 1 A cross-sectional view at point CC.

[0027] In an optional implementation, the positioning fixture in the above embodiments can be used as follows: First, the bottom surface of the seat is detachably attached to the adhesion area 121 to position the seat. Second, a first adhesive layer A31, a second adhesive layer A32, and a third adhesive layer A33 are coated on the top of the seat, wherein the third adhesive layer A33 is disposed on the top surface of the second plate A62 and located between the first plate A61 and the connecting end A2 (e.g., Figure 3 (As shown). This allows the second plate A62 to be bonded to the side plate A42 via the first adhesive layer A31, thereby increasing the overall structural strength of product A and ensuring that the connecting end A2 will not easily bend. The second adhesive layer A32 and the third adhesive layer A33 are used to bond the cover A41 to the lens A5 and the first plate A61. Optionally, before the base is placed in the adhesion area 121, the first adhesive layer A31, the second adhesive layer A32, and the third adhesive layer A33 are applied to the base. Then, the cover A4 is placed on the base and simultaneously bonded to the first adhesive layer A31, the second adhesive layer A32, and the third adhesive layer A33 (e.g., ...). Figures 9-10 (As shown). Finally, the adhesive is baked to cure.

[0028] Throughout the process described above, the bottom surface of the base remains in contact with the adhesive pad 12. In this configuration, during the process of the cover A4 being placed on the base and during the baking of product A, the flexible circuit board A6 remains flat, preventing it from bending or deforming. This improves the installation accuracy of the base and cover A4 and prevents the connecting end A2 from warping.

[0029] In summary, the positioning fixture in this embodiment attaches one side of the adhesive pad 12 to the top of the carrier plate 11, so that multiple adhesion areas 121 are formed on the other side of the adhesive pad 12 to fix the product A. When the carrier plate 11 is placed on the bearing surface 21, the carrier plate 11 is adsorbed by the multiple suction holes 22 of the bearing surface 21, so that the product A is indirectly positioned by the positioning part 2. Thus, during the assembly process of the product A, the seat of the product A can be stably attached to the adhesive pad 12, avoiding displacement of the seat. At the same time, during the curing process of the adhesive of the product A, the flexible circuit board A6 can remain in a flat state, effectively preventing the connecting end A2 from warping, and improving the installation accuracy of the cover A4 and the seat.

[0030] Furthermore, the adhesive pad 12 is made of rubber or silicone. Using silicone and rubber materials gives the adhesion area 121 high friction, preventing horizontal displacement of product A. Simultaneously, the adhesive pad 12 deforms under pressure, allowing the bottom of product A to adhere more closely to the adhesive pad 12. Moreover, the surface of the rubber or silicone has a certain degree of adhesiveness, ensuring that the bottom of product A adheres to the adhesive pad 12. In addition, the rubber or silicone has good heat resistance, effectively preventing changes in the adhesion of product A to the adhesive pad 12 during baking.

[0031] In some implementations, such as Figure 8 As shown, both the carrier tray 11 and the adhesive pad 12 include multiple clearance holes 3. The multiple clearance holes 3 of the carrier tray 11 are respectively provided corresponding to the multiple clearance holes 3 of the adhesive pad 12. The multiple clearance holes 3 of the adhesive pad 12 are located in multiple adhesion areas 121. In this embodiment, a part of the bottom area of ​​product A is suspended, so that the ejector head can lift product A from the adhesive pad 12 through the clearance holes 3 to separate product A from the adhesive pad 12.

[0032] Furthermore, the multiple suction holes 22 are staggered from the multiple clearance holes 3. This prevents the suction holes 22 from directly adsorbing product A.

[0033] In some implementations, such as Figure 8 As shown, the adhesion area 121 has multiple clearance holes 3, including a first clearance hole 31 and a second clearance hole 32. The first clearance hole 31 corresponds to the QR code A1 on the bottom of product A, and the second clearance hole 32 corresponds to the connecting end A2 of product A. In this embodiment, the first clearance hole 31 is used to enable the identification device to identify product A from the bottom of the carrier part 1 through the QR code A1, thereby optimizing the process. In addition, the ejector head can abut against the area where the connecting end A2 of product A is located through the second clearance hole 32, reducing the bending of the connecting end A2 of the flexible circuit board A6 during the separation process.

[0034] In some implementations, such as Figure 8 As shown, the plurality of clearance holes 3 in the adhesion area 121 include two third clearance holes 33. The two third clearance holes 33 are located on the side of the first clearance hole 31 away from the second clearance hole 32, and the two third clearance holes 33 correspond to the edge of the bottom of the product A. Thus, the two third clearance holes 33 work together with the second clearance hole 32 to allow the multiple ejector heads to lift the product A simultaneously, preventing the product A from sticking to the adhesive pad 12.

[0035] In one alternative implementation, such as Figures 4-5As shown, the positioning fixture in the above embodiment can be applied to assembly equipment. The assembly equipment also includes a conveying unit 4, a baking unit 5, and a mounting unit 6. The conveying unit 4 conveys the carrier unit 1 and product A to the baking unit 5 via the mounting unit 6. The baking unit 5 is used to heat and bake product A to cure the adhesive. When the carrier unit 1 is mounted in the mounting unit 6, the side of the carrier plate 11 facing away from the adhesive pad 12 is disposed on the bearing surface 21 and is disposed opposite to the plurality of suction holes 22. The mounting unit 6 is provided with a plurality of gripping heads, which grip the cover A4 respectively to simultaneously cover the plurality of cover A4 onto the corresponding seat.

[0036] In summary, the assembly equipment in this embodiment attaches one side of the adhesive pad 12 to the top of the carrier tray 11, so that multiple adhesion areas 121 are formed on the other side of the adhesive pad 12 to fix the product A. When the carrier tray 11 is placed on the bearing surface 21, the carrier tray 11 is adsorbed by multiple suction holes 22 on the bearing surface 21, so that the product A is indirectly positioned by the positioning part 2. Thus, during the assembly process of the product A, the seat of the product A can be stably attached to the adhesive pad 12, avoiding displacement of the seat. At the same time, during the curing process of the adhesive of the product A, the flexible circuit board A6 can remain in a flat state, effectively preventing the connecting end A2 from warping, and improving the installation accuracy of the cover A4 and the seat.

[0037] In some implementations, such as Figure 6 As shown, the positioning part 2 includes a positioning platform 23, and the platform surface of the positioning platform 23 forms a bearing surface 21. Further referring to... Figure 5 As shown, the carrier tray 11 includes two driving edges 111. The carrier tray 11 and the suction hole 22 are in a suction state, and the two driving edges 111 extend to both sides of the positioning stage 23. The conveying unit 4 includes two conveyor belts 41 corresponding to the two driving edges 111. The two conveyor belts 41 respectively abut against the bottom of the corresponding driving edge 111 to convey the carrier unit 1. Thus, the two conveyor belts 41 improve the stability of the carrier unit 1 during conveying, ensuring that the carrier unit 1 can stably carry multiple products A.

[0038] In some implementations, such as Figure 5 As shown, the assembly equipment also includes a lifting unit 7. The lifting unit 7 includes a drive component (specific structure not shown in the figure), which is connected to the bottom of the positioning unit 2. When the carrying unit 1 is in the mounting unit 6, the lifting unit 7 moves the positioning fixture upward via the drive component, so that the mounting unit 6 can mount the cover A4 of product A. Simultaneously, the lifting unit 7 moves the positioning fixture downward via the drive component, so that the two drive edges 111 are placed on the conveyor belt 41. This facilitates the conveying unit 4 to transport the carrying unit 1 to the baking unit 5.

[0039] Furthermore, both the carrier tray 11 and the adhesive pad 12 include a plurality of clearance holes 3. The plurality of clearance holes 3 of the carrier tray 11 are respectively disposed corresponding to at least a portion of the plurality of clearance holes 3 of the adhesive pad 12, and the plurality of clearance holes 3 of the adhesive pad 12 are located in a plurality of adhesion areas 121. The assembly equipment also includes an ejector section. The ejector section includes a plurality of ejector heads respectively disposed corresponding to at least a portion of the plurality of clearance holes 3. The ejector heads pass through the corresponding clearance holes 3 from below the carrier section 1 to lift the product A, thereby separating the product A from the adhesive pad 12. Thus, in this embodiment, the ejector section drives the separation of multiple products A from the adhesive pad 12, improving the processing efficiency of product A.
