Technical Field

[0001] This utility model relates to the field of camera module production technology, specifically to a pressure holding and shaping tooling for camera modules after dispensing adhesive. Background Technology

[0002] In the assembly of camera modules (such as AR / AI smart glasses), dispensing and pressure holding are critical processes used to secure the lens module, flexible printed circuit board (FPC), and other components. Existing conventional tooling has the following shortcomings: 1. Low positioning accuracy: This causes the optical axis to shift after the camera module is assembled, affecting the image quality.

[0003] 2. Inefficient: The operation process is complicated, it is inconvenient to pick up and put down products, and the cycle time is long, which cannot meet the needs of mass production. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient precision and low efficiency in camera module assembly. To this end, a pressure holding and shaping fixture for camera module after dispensing adhesive is provided. By effectively positioning the camera module, the operation process is simplified to solve the above problems.

[0005] The technical solution adopted to solve the above problems is: A pressure-holding and shaping fixture for camera modules after dispensing adhesive is proposed, comprising a base plate, a support plate, a pressure plate assembly, and a pressure-holding assembly. The support plate is disposed on the base plate and has multiple cavity holes for accommodating the camera modules. The pressure plate assembly includes a pressure plate fixing seat and a pressure plate. The pressure plate is hinged to the upper end of the pressure plate fixing seat and can be flipped up and down along the hinge axis. The pressure plate is provided with a contour block for pressing the flexible circuit board on the camera module. The pressure holding assembly includes a pressure holding plate, on which a spring pressure block system is integrated to provide pressure to ensure that the camera module remains stationary and pressure-holding without displacement after dispensing.

[0006] Furthermore, the pressure plate and the support plate are magnetically connected; specifically, this includes a magnet or iron sheet disposed on the pressure plate, and a corresponding iron sheet or magnet on the support plate.

[0007] Furthermore, the bearing plate is provided with a first groove, and the pressure plate has a pressure plate protrusion corresponding to the first groove; Magnets or iron sheets are respectively placed at the bottom of the first groove and on the end face of the pressure plate protrusion.

[0008] Furthermore, the spring pressure block system includes a height equalizing screw and a spring. The pressure plate has a vertical spring groove, and a bolt hole is formed vertically downward from the bottom of the spring groove to the base plate. The spring is disposed in the spring groove, the height equalizing screw passes through the bolt hole and is threaded to the base plate, and the upper end of the spring abuts against the nut of the height equalizing screw and the lower end abuts against the bottom of the spring groove.

[0009] Furthermore, the pressure holding plate has a pressure holding protrusion, the bearing plate is provided with a second groove, and the pressure holding protrusion is vertically inserted into the second groove; the spring groove and the bolt hole are both located in the area where the pressure holding protrusion is located.

[0010] Furthermore, the pressure plate and the support plate are magnetically connected; specifically, this includes a magnet or iron sheet disposed on the pressure plate, and a corresponding iron sheet or magnet on the support plate.

[0011] Furthermore, the pressure holding plate has two working states: an initial working position and a pressing working position; the pressure holding plate is provided with positioning holes, and the bearing plate is provided with several positioning pins, which correspond to the positioning holes on the pressure holding plate in the initial working position and the positioning holes on the pressure holding plate in the pressing working position, respectively.

[0012] Furthermore, positioning holes are provided at both the front and rear ends of the pressure holding plate.

[0013] Furthermore, the bearing plate is also provided with a foolproof post. When the pressure plate is in the pressing position, the foolproof post is located on one side of the pressure plate to ensure that the rotation position of the pressure plate is correct.

[0014] Furthermore, the support plate is made of antistatic POM board, and the pressure plate and holding plate are made of antistatic PEEK board; a bushing is provided on each acupoint for error prevention design.

[0015] The beneficial effects of this utility model are: 1.

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and by way of embodiments. For ease of description, only the parts related to this utility model are shown in the drawings, not the entire structure.

[0018] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0021] Please see Figure 1-7 This embodiment proposes a pressure-holding and shaping fixture for camera modules after adhesive dispensing, including a base plate 1, a support plate 2, a pressure plate assembly 5, and a pressure-holding assembly 6. The support plate 2 is disposed on the base plate 1 and has several slots for placing camera modules 4 (products). The pressure plate assembly 5 and the pressure-holding assembly 6 are distributed around each slot to press and position the product placed in the slot. Specifically, the pressure plate assembly 5 is used to press the product inside the slot to prevent it from lifting or being scratched during subsequent operations; the pressure-holding assembly 6 presses the product outside the slot to keep the product stable during static placement and promote UV curing or adhesive setting.

[0022] Specifically, the base plate 1 is made of aluminum alloy, and its edges are rounded to meet EHS safety standards. The support plate 2 is fixed to the base plate 1 with bolts. To ensure that the support plate 2 does not shift laterally after installation, positioning pins can be added to cooperate with the bolts to achieve a detachable and fixed connection of the support plate 2.

[0023] The pressure plate assembly 5 includes a pressure plate fixing seat 51 and a pressure plate 52. The fixing seat 51 is fixed to the base plate 1 by bolts. One end of the pressure plate 52 is hinged to the upper end of the pressure plate fixing seat 51, allowing the pressure plate 52 to rotate up and down along the hinge axis 53. The rotation angle of the pressure plate 52 is controlled between 0-90°. The pressure plate 52 has a contour block 521 for pressing the flexible circuit board (FPC) on the camera module 4 to prevent it from warping or being scratched during subsequent operations.

[0024] The pressure holding assembly 6 includes a pressure holding plate 61, on which a spring pressure block system is integrated to provide relatively stable pressure to ensure that the product remains stationary without displacement after dispensing. The spring pressure block system includes equal-height screws 62 and springs 63.

[0025] Specifically, the pressure plate 61 has a pressure-holding protrusion 611, and the bearing plate 2 has a second groove. The pressure-holding protrusion 611 is vertically inserted into the second groove. The pressure plate 61 has a vertical spring groove, and a bolt hole extends vertically downward from the bottom of the spring groove to the base plate 1. During installation, the spring is first placed in the spring groove, and then the equalizing screw 62 is inserted into the spring 63 and threaded downward along the bolt hole to the base plate 1. At this time, the upper end of the spring 63 abuts against the nut of the equalizing screw 62, and the lower end abuts against the bottom of the spring groove. Simultaneously, the pressure plate 61 has a pressure-holding groove 614 for pressing the product.

[0026] In this design, the carrier plate 2 is made of anti-static POM board, which can effectively release static electricity and prevent electrostatic damage to the internal electronic components of the camera module 4. The bushings 7 at the edge of each acupoint are preferably anti-static silicone bushings or anti-static POM bushings. One side of the bushing 7 has a foolproof design, ensuring that the camera module 4 can only be inserted into the acupoint when placed in the preset direction, preventing reverse installation. Both the pressure plate 52 and the pressure holding plate 61 are made of anti-static PEEK board, which can eliminate frictional static electricity and ensure that electrostatic damage to the electronic components of the camera module 4 is not generated during operation.

[0027] As an important and essential technical feature of this embodiment, the pressure plate 52 and the support plate 2 are magnetically connected. Specifically, a magnet or iron sheet is provided on the pressure plate 52, and a corresponding iron sheet or magnet is provided on the support plate 2. Through magnetic adsorption, the pressure plate 52 is fixed on the support plate 2 when pressed together.

[0028] Furthermore, a first groove is provided on the support plate 2, and a pressure plate 52 has a pressure plate protrusion 522 corresponding to the first groove. A corresponding magnet or iron sheet is placed at the bottom of the first groove and on the end face of the pressure plate protrusion 522, respectively, and an anti-static coating is applied to the surface to achieve the aforementioned magnetic attraction. This structure ensures stable adsorption force, allowing the pressure plate 52 to tightly press against the FPC and prevent warping. Simultaneously, the pressure plate 52 can be easily separated from the support plate 2 manually without affecting operational efficiency, and the magnetic attraction structure has no mechanical wear, extending the tooling's service life.

[0029] As a crucial technical feature of this embodiment, the pressure plate 61 and the support plate 2 are magnetically connected. Specifically, a magnet or iron sheet is provided on the pressure plate 61, and a corresponding iron sheet or magnet is provided on the support plate 2, with an anti-static coating applied to the surface, allowing the pressure plate 61 to be magnetically attracted to the support plate 2. Furthermore, the corresponding magnet or iron sheet is placed on the lower end face of the pressure protrusion 611 and the bottom of the second groove, respectively, to achieve the aforementioned magnetic attraction. This structure ensures stable adsorption force.

[0030] As a crucial technical feature of this embodiment, the pressure plate 61 is provided with positioning holes, and corresponding positioning pins are provided on the support plate 2. In use, the pressure plate 61 is lifted upwards, at which point the spring is in a contracted state. The angle of the pressure plate 61 is manually adjusted by 90 degrees to move it from the initial position to the pressing position. At this time, the positioning holes on the pressure plate 61 are precisely aligned with the corresponding positioning pins and inserted. The pin holes restrict the horizontal displacement of the pressure plate 61, and together with the aforementioned magnetic attraction structure, further ensure the precise pressing position of the pressure-holding protrusions on the camera module 4, preventing product displacement during the pressure-holding process.

[0031] In this design, the bearing plate 2 has multiple positioning pins, corresponding to the initial and clamping states of each pressure plate 61. Both the front and rear ends of the pressure plate 61 have a first positioning hole 613 and a second positioning hole 612. When the pressure plate 61 is in the initial position, the first positioning holes 613 and 612 at both ends are respectively fitted onto the corresponding second positioning pin 82 and first positioning pin 81. When the pressure plate 61 is in the clamping position, the first positioning holes 613 and 612 are respectively fitted onto the corresponding third positioning pin 83 and fourth positioning pin 84, serving as X-axis limiters to restrict wobbling and ensure positioning stability.

[0032] Furthermore, a foolproof post 9 is also provided on the bearing plate 2. When the pressure plate 61 is in the clamping position, the aforementioned foolproof post 9 is located on one side of the pressure plate 61. By limiting the movement of the foolproof post 9, the pressure plate 61 can rotate to the clamping position by rotating only 90° in the correct direction (such as clockwise) to avoid the foolproof post 9.

[0033] A further implementation scheme involves providing handles 3 on both sides of the base plate 1 for ease of handling. These handles 3 are bolted to the edges of both sides of the base plate 1 for convenient manual handling.

[0034] Camera module dispensing and pressure holding process: like Figure 1 The initial state is shown, where the pressure plate 61 is in the initial position and the pressure plate 52 is in a non-pressurized state. The operator manually places the four sets of camera modules 4 into the tooling cavity in sequence, and uses the bushing to ensure that the camera modules 4 are correctly placed in the cavity.

[0035] like Figure 3 As shown, the pressure plate 52 is then pressed firmly into the acupoint. At this point, the position of the pressure plate 52 is fixed by magnetic attraction, achieving zero-gap pressing and preventing the FPC from warping. The entire fixture is then fed into the dispensing equipment, automatically completing the dispensing process. High-precision positioning of the fixture during dispensing prevents glue overflow.

[0036] After the adhesive is applied, the operator manually assembles the brackets one by one. The fixture's acupoint design makes the brackets easy to align, and the pressure plate assembly 5 maintains the FPC's pre-folded angle to prevent springback.

[0037] like Figure 4 As shown, manually engage the pressure plate 61 and hold it in place. A constant pressure (2.7N) is provided by the spring, ensuring product stability during the resting process and promoting UV curing or adhesive setting. The pressure holding time is integrated into the cycle, with a total operation time of less than 40 seconds.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
