[0045] Embodiment 1:

[0046] The present invention provides a camera module dispensing fixture, such as Figures 1 to 5 As shown, it includes a bottom plate 1, a shovel 2 and a cover plate 3. A groove is provided on the bottom plate 1 for installing the camera module. The camera module includes a module body, a pan-tilt and a packaging sheet. One end of the module body is connected to a folded soft flat cable, and the other end is connected to a connector. After the pan-tilt is installed in the groove, the module body is installed in the pan-tilt, the packaging sheet is installed on the module body, and the cover plate 3 is snapped on the bottom plate 1 to press the camera module. The shovel 2 is slidably connected to the bottom plate 1, and the shovel 2 is inserted into the folded soft flat cable by sliding, so that the soft flat cable is pressed against the tail of the pan-tilt.

[0047] like Figure 2As shown, specifically, the plate surface of the base plate 1 is recessed toward the bottom to form a first groove 11 and a second groove 12. The contour of the first groove 11 is adapted to the contour of the gimbal, and the gimbal is installed in the first groove 11. The contour of the second groove 12 is adapted to the contour of the connector. After the module body is installed in the gimbal, the connector is installed in the second groove 12. The first groove 11 and the second groove 12 together form a groove on the base plate 1, and the depth of the first groove 11 is greater than the depth of the second groove 12. A lens hole 13 is provided in the first groove 11, and the contour of the lens hole 13 is adapted to the contour of the lens on the module body. The lens is installed in the lens hole 13, and the entire camera module is inverted in the groove of the base plate 1.

[0048] like Figure 2 As shown, a pedestal 21 higher than the surface of the bottom plate 1 is provided on the bottom plate 1, and the pedestal 21 is away from the groove so that the first groove 11 is located between the pedestal 21 and the second groove 12. The surface of the pedestal 21 is recessed toward the bottom plate 1 to form a third groove 24, and the contour of the third groove 24 is adapted to the contour of the end of the flexible flat cable, and the end of the flexible flat cable is installed in the third groove 24. A magnet hole 14 is provided on the bottom plate 1 between the third groove 24 and the first groove 11, and a magnet for adsorbing the camera module is installed in the magnet hole 14. In addition, a tape groove 17 for installing a tape is also provided on the surface of the bottom plate 1 between the third groove 24 and the first groove 11, so that the camera module is also fixed to the bottom plate 1 by the tape.

[0049] like Figure 2 and Figure 4 As shown, the shovel blade 2 includes a slide 211 and a shovel tongue 212. The two ends of the slide 211 are bent to the outer side walls of the two ends of the base 21, so that the slide 211 can be slidably connected with the base 21. A limiting column 22 is provided on the base 21, and a waist-shaped hole 23 is provided on the slide 211. The limiting column 22 is inserted into the waist-shaped hole 23 to allow the slide 211 to slide relative to the base 21. One end of the shovel tongue 212 is fixedly connected to the slide 211, and the other end of the shovel tongue 212 is close to the bottom plate 1, and the entire shovel tongue 212 is inclined relative to the bottom plate 1. During the sliding process, the shovel tongue 212 is inserted into the folded soft cable at the bottom through the end close to the bottom plate 1, and the folded soft cable is pushed against the inclined portion, so that the soft cable is pressed tightly on the pan-tilt head.

[0050] like Figure 5As shown, a glue dispensing window 31 is provided on the cover plate 3, and the glue dispensing window 31 is located directly above the groove. The projection area of ​​the glue dispensing window 31 on the base plate 1 is larger than the area of ​​the camera module, and the camera module can be conveniently glued through the glue dispensing window 31. The cover plate 3 is connected with a pressing sheet 32 ​​extending into the glue dispensing window 31, and the cover plate 3 presses the camera module through the pressing sheet 32, and the pressing sheet 32 ​​avoids the glue dispensing path of the camera module. The edge of the base plate 1 is connected with a plurality of magnetic columns 15 and positioning columns 16, and a plurality of connection holes corresponding to the positions of the magnetic columns 15 and the positioning columns 16 are provided on the cover plate 3. The cover plate 3 is adsorbed on the base plate 1 through the plurality of magnetic columns 15 and the positioning columns 16, so as to realize the detachable connection between the cover plate 3 and the base plate 1.

[0051] The present invention fixes the pan / tilt via the grooves on the bottom plate 1, presses the module body via the cover plate 3, and presses the flexible flat cable via the shovel 2, thereby achieving the fixation of the pan / tilt, the module body, and the flexible flat cable, avoiding the displacement of the pan / tilt, the module body, and the flexible flat cable during the dispensing process, thereby ensuring the positioning accuracy and flatness of the camera module, ensuring the stability of the camera module during the dispensing process, avoiding the rebound of the flexible flat cable after folding, and ensuring the connection strength between the flexible flat cable and the pan / tilt. Using the dispensing jig of the present invention, at least dispensing can be achieved at multiple positions such as between the flexible flat cable and the tail of the pan / tilt, between the module body and the pan / tilt, and between the module body and the packaging sheet.

[0052] It is understandable that the detachable connection between the cover plate 3 and the base plate 1 in the present invention can also be realized by a connection structure such as bolts or buckles. The sliding connection between the shovel blade 2 and the base 21 can also be realized by a structure in which a slide rail and a slide groove cooperate. According to the actual specifications and dimensions of the camera module, the area of ​​the groove, the size of the cover plate 3, and the area of ​​the glue dispensing window 31 on the cover plate 3 can all be adaptively adjusted, so that the glue dispensing fixture of the present invention can be applicable to the dispensing of camera modules of various specifications.

[0053] like Figure 1 As shown, multiple arrays of slots and shovel blades 2 are respectively arranged on the bottom plate 1, and the multiple arrays of slots and shovel blades 2 can be rectangular arrays or circular arrays. A cover plate 3 is arranged on the top of each group of slots and shovel blades 2, and multiple cover plates 3 are connected to form an integral structure, which can realize batch dispensing of camera modules. At the same time, slide grooves adapted to the sliding tracks of the machine are arranged on both sides of the bottom plate 1. When the camera module is finished dispensing, it can be moved to the next process through the slide groove, which effectively reduces the transition time between processes and improves the efficiency of camera module production and processing.

[0054] Embodiment 2:

[0055] The present invention also provides a camera module dispensing method, such as Figure 6As shown, first, paste a high temperature resistant tape in the tape groove 17, and clamp the pan / tilt into the first groove 11 on the bottom plate 1 by the clamping claws to fix the pan / tilt and apply glue to the tail a of the pan / tilt. Then, the module body is adsorbed into the pan / tilt through the suction nozzle, so that the end of the soft flat cable on the module body is pasted on the tape, and at the same time, the folded part of the soft flat cable is located at the tail a of the pan / tilt. The connector on the module body is installed in the second groove 12, and the lens on the module body is installed in the lens hole 13 to ensure the installation accuracy of the module body. A magnet is installed in the magnet hole 14, so that the module body and the pan / tilt are also fixed by magnet adsorption to avoid shaking of the module body during the gluing process. Next, insert the shovel blade 2 into the bottom layer of the soft flat cable, so that the shovel blade 2 presses the folded soft flat cable against the tail a of the pan / tilt. After the shovel blade 2 is in place, it is adsorbed on the tail a of the pan / tilt by the magnet to avoid rebound of the folded soft flat cable. Finally, the cover plate 3 is covered on the bottom plate 1 through the magnetic pillars 15 and the positioning pillars 16 to press the module body.

[0056] When dispensing glue, glue is dispensed at the junction b between the pan-tilt head and the module body through the glue dispensing window 31. In particular, the edge of the glue dispensing window 31 can be set just above the junction b between the pan-tilt head and the module body, so that the edge of the glue dispensing window 31 can guide the glue dispensing and ensure the quality of the glue dispensing. Then, glue is applied to the interface c between the module body and the encapsulation sheet, and the encapsulation sheet is covered on the module body.

[0057] After the glue dispensing is completed, the entire glue dispensing fixture and the camera module are placed in an oven and baked until the glue is dry, and then the cover plate 3, the shovel 2 and the camera module are removed from the base plate 1 in turn to complete the entire glue dispensing process.

[0058] The dispensing method of the present invention can realize the rapid loading and unloading of the camera module, and can realize the rapid positioning and fixing of the camera module through the shovel 2 and the cover plate 3, and ensure the flatness of the camera module. The dispensing fixture and method of the present invention have low processing cost, wide application range, and good economic benefits.

[0059] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
