Description

Technical Field

[0001] This invention relates to the field of camera module processing technology, and in particular to a small-sized camera module structure and manufacturing equipment. Background Technology

[0002] With the rapid development of mobile terminals, medical endoscopes, micro-robots and other fields, extremely stringent requirements have been placed on the size of camera modules, urgently necessitating their evolution towards miniaturization and high performance. Against this backdrop, a type of extremely small camera module with dimensions only about millimeters in length, width and height has emerged. While meeting basic imaging functions, it also needs to integrate supplementary lighting elements (such as LEDs) to cope with low-light environments.

[0003] Currently, the industry commonly employs a highly manual assembly process for manufacturing such modules on the micrometer to millimeter scale. Please refer to the accompanying diagrams in the instruction manual. Figure 1 The existing technical solution typically includes the following steps: First, the operator, with the aid of a microscope, uses precision tools to position the imaging sensor chip and the miniature supplementary LED beads. Next, the electrodes of the LED beads are connected to the corresponding circuit pads by manual wire bonding to achieve electrical conductivity. After bonding, a micro-dispensing device is used to apply fast-drying adhesive (such as UV adhesive) to the bottom or side of the LED beads, bonding and fixing them to the imaging sensor module or substrate to form an integrated functional module.

[0004] However, the aforementioned existing technical solutions have several inherent and insurmountable defects that severely restrict the reliability, consistency, and large-scale production of the products: Because the modules and components are extremely small (for example, LED beads can be as small as 0.6mm, 0.3mm, or 0.3mm), the entire assembly process is highly dependent on the operator's skill and stability. Manual soldering, dispensing, and mounting processes are time-consuming and labor-intensive, resulting in extremely low production capacity and large fluctuations in yield, which cannot meet the demands of modern electronics manufacturing for large-scale, high-efficiency production.

[0005] Manual wire soldering makes it difficult to guarantee the consistency, accuracy, and mechanical strength of the solder joints. Messy wires can not only cause signal crosstalk, affecting image quality and illumination stability, but also easily lead to open circuits or poor contact due to vibration, thermal expansion and contraction, etc., causing module malfunction.

[0006] The bonding method relying on quick-drying adhesives has very limited bonding area and strength when dealing with tiny LED beads. The aging of the adhesive layer, stress changes under thermal cycling, and even minor external mechanical impacts can easily cause the LED beads to fall off, making the overall module structure unstable and significantly reducing product lifespan and reliability. Summary of the Invention

[0007] The present invention provides a small-sized camera module structure and manufacturing equipment, which can solve the following problems existing in the prior art: 1) Low production efficiency and inability to achieve batch automated production; 2) Poor reliability of electrical connection; 3) Weak mechanical structure strength and insufficient reliability.

[0014] Preferably, the positioning module includes an L-shaped bracket fixed to the loading plate, a limiting plate fixedly arranged on one side of the loading platform, and a positioning groove for embedding the limiting plate is formed between the L-shaped bracket and the loading plate.

[0022] Embodiment 1

[0023] As Figures 2 to 5 shown, a small-size camera module structure provided by an embodiment of the present invention includes a bottom plate 3, a camera imaging sensor module 1, a supplementary light LED module 2, and bottom filling glue; Specifically, in this embodiment, the camera imaging sensor module 1 and the supplementary light LED module 2 are fixed on the preset pads of the bottom plate 3 through a mounting device; it can be explained that the mounting device specifically adopts the SMT process (such as reflow welding) to batch-mount the camera imaging sensor module 1 and the supplementary light LED module 2 on the bottom plate 3.

[0024] It should also be noted that the supplementary light LED module 2 in this embodiment consists of a lifting bracket 201 as a carrier and a plurality of LED lamp beads 202 mounted on its upper surface through SMT; among them, the material of the lifting bracket 201 can be selected from ceramics or glass fibers that are easy to precisely cut, and its lower surface is provided with pads corresponding to the bottom plate 3; After the small-size camera module in this embodiment is assembled, an epoxy resin-based bottom filling glue is injected into the gap between the bottom plate 3, the camera imaging sensor module 1, and the supplementary light LED module 2 through a dispensing process. The filling glue fully penetrates and cures through capillary action, firmly combining each component into a whole; As an implementation manner of this embodiment, the structure of the supplementary light LED module 2 can be designed according to needs, Figure 3 shows an embodiment in which two groups of supplementary light LED modules 2 are arranged in a crescent shape around the side of the camera imaging sensor module 1; Figure 4 shows an embodiment in which the supplementary light LED module 2 and the camera imaging sensor module 1 are arranged in a "pin" shape; Figure 5An embodiment is shown in which the supplementary light LED module 2 and the camera imaging sensor module 1 are arranged in a straight line. Based on this, the specific layout structure of the supplementary light LED module 2 and the camera imaging sensor module 1 can be set according to the actual application scenario. This embodiment does not limit this, as long as it meets the actual application requirements.

[0027] The cutting equipment in this embodiment can be a laser cutting machine or a wafer cutting machine of the prior art. This embodiment does not limit the specific model, as long as it meets the actual application requirements.

[0028] Example 2

[0029] Please refer to Figures 8-11A manufacturing device for a small-sized camera module structure includes a mounting device. The mounting device includes a work box 4, which contains a first loading module for loading a bracket plate 601 and a second loading module for loading LED beads 202. Specifically, in this embodiment, before mounting the LED beads 202 onto the bracket plate 601 using the SMT surface mount process, the first loading module loads the bracket plate 601 into the work box 4, and then the second loading module loads the LED beads 202 into the work box 4, so as to facilitate the subsequent mounting process of the LED beads 202 and the bracket plate 601.

[0030] As one embodiment of this invention, the work box 4 is also provided with a transfer module, which is used to uniformly mount the loaded LED beads 202 onto the bracket plate 601. It can be noted that after the first loading module and the second loading module of this embodiment have completed loading the bracket plate 601 and the LED beads 202 respectively, the transfer module then moves the LED beads 202 and uniformly mounts them onto the bracket plate 601. After the mounting of the LED beads 202 on the bracket plate 601 is completed, the bracket plate 601 can be unloaded. In this embodiment, the mounting process of the LED beads 202 and the bracket plate 601 can be automatically completed by the mounting equipment, which effectively improves the mounting efficiency of the LED beads 202 and the bracket plate 601.

[0031] In this embodiment, the first feeding module includes a feeding platform 6 for carrying the bracket plate 601. The feeding platform 6 is connected to a conveying component, which is used to convey the feeding platform 6 to the mounting position. It can be noted that in this embodiment, when feeding the bracket plate 601, the bracket plate 601 is first placed on the feeding platform 6, and then the feeding platform 6 is conveyed to the mounting position by the conveying component to facilitate subsequent mounting processing.

[0032] Please refer to Figure 9The two side walls of the work box 4 are respectively provided with material grooves 402. The first feeding module includes a first conveying platform 401 fixed inside the work box 4. The two ends of the first conveying platform 401 extend through the material grooves 402 to the outside of the work box 4. A translation module 602 is fixedly arranged on one side of the first conveying platform 401. The driving end of the translation module 602 is fixedly connected to the feeding plate 603. Several sets of positioning modules are fixedly arranged at equal intervals on the feeding plate 603. The positioning modules are used to fix the feeding platform 6. It can be noted that in this embodiment, during feeding, the feeding platform 602 can be used to move the material to the outside of the work box 4. The material plate 603 moves along the material groove 402 to the outside of the work box 4, and then the bracket plate 601 to be mounted is moved to the loading platform 6. Then, the mounting plate 601 is transported to the mounting position of the work box 4 by the translation module 602. After mounting is completed, the translation module 602 moves the loading plate 603 out to unload the mounted bracket plate 601. This embodiment sets multiple sets of bracket plates 601, which can complete the loading of multiple sets of bracket plates 601 at one time and improve efficiency, avoiding frequent loading and unloading operations by operators and ensuring production efficiency.

[0033] Specifically, the translation module 602 in this embodiment can adopt a synchronous belt drive mechanism or a lead screw and nut drive mechanism. This embodiment does not limit the specific model, as long as it meets the actual application requirements.

[0034] As one implementation method of this embodiment, please refer to Figure 11 The positioning module includes an L-shaped bracket 604 fixed to the loading plate 603. A limiting plate 606 is fixedly arranged on one side of the loading platform 6. The L-shaped bracket 604 and the loading plate 603 form a positioning groove 605 for embedding into the limiting plate 606. At least two sets of positioning holes 607 are opened on the limiting plate 606. Positioning rods 608 for engaging with the positioning holes 607 are inserted into the L-shaped bracket 604. The end of each positioning rod 608 away from the loading plate 603 is fixedly connected by a lifting plate 609. The positioning rod 608 is provided with a return spring 610. One end of the return spring 610 is fixedly connected to the L-shaped bracket 604, and the other end is fixedly connected to the lifting plate 609. It can be noted that in the initial state, the base With the reset spring 610 in place, each positioning rod 608 is positioned on the side closest to the loading plate 603. When installing the loading platform 6, first pull the lifting plate 609 upwards. The lifting plate 609 drives each positioning rod 608 to move away from the loading plate 603. During the movement, the loading plate 603 causes the reset spring 610 to stretch and generate elastic force. After the limiting plate 606 is embedded into the positioning groove 605, the operator releases the lifting plate 609. Under the elastic force of the reset spring 610, each positioning rod 608 can be driven to embed into the positioning hole 607, thereby achieving the effect of positioning and fixing the limiting plate 606. Correspondingly, when disassembling, pull the lifting plate 609 upwards again to remove the loading platform 6. The operation is very convenient.

[0035] In this embodiment, the second feeding module includes a second feeding platform 403 fixed inside the work box 4. Both ends of the second feeding platform 403 extend through the material trough 402 to the outside of the work box 4. Two sets of pulleys 407 are symmetrically arranged on the second feeding platform 403. One set of pulleys 407 is fixedly connected to the drive end of the servo drive device fixed on the second feeding platform 403. Feeding conveyor belts 404 are sleeved on the pulleys 407 on both sides. Specifically, the feeding conveyor belt 404 in this embodiment has a certain width along the axial direction of the pulleys 407. When feeding the LED beads 202, the robot arm arranges the LED beads 202 on the feeding conveyor belt 404. As the servo drive device drives the pulleys 407 to rotate, the pulleys 407 on both sides synchronously drive the feeding conveyor belt 404 to convey the LED beads 202 towards the mounting end of the work box 4, so as to facilitate the subsequent mounting of the LED beads 202 with the bracket plate 601.

[0036] As a further embodiment, in order to ensure that each bracket plate 601 is stably conveyed on the feeding conveyor belt 404, several sets of baffles 405 are evenly fixedly arranged on both sides of the conveyor belt 404. The two rows of baffles 405 and the conveyor belt 404 enclose each other to form a conveying groove 406 for conveying LED beads 202. It can be noted that when feeding LED beads 202 in this embodiment, the material groove 402 is first evenly arranged on the conveying groove 406 outside the material groove 402. During the conveying process, the LED beads 202 in the conveying groove 406 can be guided and limited by the two rows of baffles 405 to ensure the stability of the conveying of LED beads 202.

[0037] Please refer to Figures 8-9 The transfer module includes a first moving mechanism 501 fixedly arranged inside the work box 4. The driving end of the first moving mechanism 501 is fixed to a second moving mechanism 502. The first moving mechanism 501 drives the second moving mechanism 502 to translate within the work box 4. A moving plate 503 is fixedly arranged on the driving end of the second moving mechanism 502. The second moving mechanism 502 drives the moving plate 503 to translate within the work box 4. The moving directions of the driving ends of the first moving mechanism 501 and the second moving mechanism 502 are perpendicular. A lifting cylinder 504 is fixedly installed on the moving end, and the driving end of the lifting cylinder 504 is fixedly connected to the transfer end head 5. It can be explained that after the second feeding module of this embodiment transports the LED lamp bead 202 to the transfer position in the working box 4, the position of the moving plate 503 can be adjusted by the cooperation of the first moving mechanism 501 and the second moving mechanism 502, and then the height of the transfer end head 5 can be adjusted by the lifting cylinder 504, so that the transfer end head 5 picks up the LED lamp bead 202 and attaches it to the bracket plate 601, thereby achieving the effect of automatic mounting. It should be noted that the first moving mechanism 501 and the second moving mechanism 502 in this embodiment can be synchronous belt drive mechanism or screw and nut drive mechanism. This embodiment does not limit their specific models and structures, as long as they meet the actual application requirements.
