[0002] In the production process of camera modules, ensuring the cleanliness of raw materials is a key step in improving the product qualification rate. In this process, raw materials such as shells, lenses, and PCBA need to be thoroughly washed before assembly to remove possible dust and other contaminants. To ensure the safety of raw materials during transportation, they are placed on special incoming material trays, which are designed to protect the raw materials to reduce the risk of damage during transportation.

This process not only has low efficiency, but also increases the possibility of damage or loss of raw materials due to repeated manual operations. In view of this, the industry urgently needs an efficient automated solution to optimize the feeding link of camera modules. Such automated equipment should be able to accurately and quickly complete the transfer of raw materials, while reducing human errors and improving the overall production efficiency and reliability.

[0046] The present utility model provides a feeding device 1000 for a camera module.

[0047] Please refer to Figure 1 、 Figure 6 and Figure 7, in an embodiment of the present utility model, the feeding device 1000 of the camera module includes a feeding tray feeding device 1, a feeding tray feeding device 2, a carrying device 3, a first conveying device 4, a transfer device 5 and a buffer device 6. The feeding tray feeding device 1 contains a feeding tray 103 carrying raw materials to be processed. The feeding tray feeding device 2 contains a feeding tray 104. The carrying device 3 is used to park the feeding tray 104. The buffer device 6 is used to store the loaded feeding tray 104. The first conveying device 4 is sequentially connected to the feeding tray feeding device 2, the carrying device 3 and the buffer device 6. The transfer device 5 grabs the raw materials to be processed from the feeding tray 103 in the feeding tray feeding device 1 and transfers them to the feeding tray 104 parked on the carrying device 3.

[0048] In this embodiment, the feeding trays 103 are stacked on the feeding tray feeding device 1. Each feeding tray 103 has two opposite side surfaces, and grooves are provided on the two opposite side surfaces to facilitate separating the stacked feeding trays 103 from each other. Similarly, the feeding trays 104 are stacked on the feeding tray feeding device 2. Each feeding tray 104 has two opposite side surfaces, and grooves are provided on the two opposite side surfaces to facilitate separating the stacked feeding trays 103 from each other. Optionally, the way of providing grooves on the two opposite side surfaces of the tray can be replaced by providing wing plates on the two opposite side surfaces of the tray, and making the thickness of the wing plates less than the thickness of the tray, which can also achieve the effect of facilitating separating the stacked feeding trays 103 from each other.

[0049] In this embodiment, the feeding trays 103 are neatly stacked at the input end of the feeding tray feeding device 1. The feeding tray feeding device 1 separates one feeding tray 103 separately and outputs it. Similarly, the feeding trays 104 are neatly stacked at the input end of the feeding tray feeding device 2. The feeding tray feeding device 2 separates one feeding tray 104 separately and outputs it. The first conveying device 4 conveys the separately separated feeding tray 104 to the carrying device 3. At this time, the feeding tray 104 is parked on the carrying device 3 waiting to be loaded. The transfer device 5 grabs the raw materials on the separately separated feeding tray 103 and transfers them to the feeding tray 104 parked on the carrying device 3 to complete the loading of the feeding tray 104. The first conveying device 4 continues to convey the loaded feeding tray 104 to the buffer device 6 for temporary storage, waiting for the next cleaning.

[0050] The conveying device in this embodiment uses belt conveying. The conveying device has two parallel belts, and the tray is transported by being placed on the two belts. In this way, the transportation process is more stable. Optionally, this belt conveying method can be replaced by roller conveying or chain conveying, etc. Similarly, the conveying devices in the following text can refer to this embodiment.

[0051] In this embodiment, the transfer device 5 is a robotic arm. A gripper 51 for gripping raw materials is provided at the free end of the robotic arm. An industrial camera is also mounted on the robotic arm for taking pictures and positioning during material picking, and at the same time for confirming whether there is a product on the tray during material picking. If there is a product, normal picture taking and positioning for material picking are performed; if there is no product, it is skipped. Optionally, the robotic arm can be replaced by a three-axis spatial movement component, and both can complete the transfer of raw materials in three-dimensional space. Compared with the three-axis spatial movement component, the robotic arm occupies less space and is more flexible in movement.

[0052] In addition, the camera module feeding device 1000 in this embodiment is equipped with a motion control management system. This system is built-in with a dedicated management program, which can centrally monitor and control the feeding device, conveying device, carrying device 3, transfer device 5, buffer device 6, etc.

[0053] The camera module feeding device 1000 of this embodiment adopts a feeding tray feeding device 1, a feeding tray feeding device 2, a carrying device 3, a first conveying device 4, a transfer device 5, and a buffer device 6. The feeding tray feeding device 1 contains a feeding tray 103 carrying raw materials to be processed, the feeding tray feeding device 2 contains a feeding tray 104, and the first conveying device 4 is sequentially connected to the feeding tray feeding device 2, the carrying device 3, and the buffer device 6. The feeding tray 104 output by the feeding tray feeding device 2 is moved to the carrying device 3 by the first conveying device 4 and parked. After the transfer device 5 moves the raw materials on the feeding tray feeding device 1 into the feeding tray 104 parked on the carrying device 3, the first conveying device 4 continues to convey the loaded feeding tray 104 to the buffer device 6 for the next cleaning. In this way, the automatic feeding of the camera module is completed, improving the efficiency and reliability of the camera module feeding.

[0054] Specifically, please refer to Figures 2 to 4In one embodiment of the utility model, the incoming material tray loading device 1 includes a first frame 11, a second conveying device 12, a first lifting mechanism 13, a first clamping mechanism 14, a second lifting mechanism 15, a storage mechanism 16, a third lifting mechanism 17 and a first stopping mechanism 18. The first frame 11 has an incoming material tray placement station 11a, an incoming material tray recovery station 11b and a material picking station 11c. The second conveying device 12 is arranged on the first frame 11 and passes through the incoming material tray placement station 11a, the incoming material tray recovery station 11b and the material picking station 11c in sequence. The input end of the second conveying device 12 is located at the incoming material tray placement station 11a, and the output end of the second conveying device 12 is located at the material picking station 11c. The first lifting mechanism 13 and the first clamping mechanism 14 are arranged at the incoming material tray placement station 11a, and the output end of the second conveying device 12 is located at the material picking station 11c. The first lifting mechanism 13 drives the incoming material pallet 103 to move to the input end of the second conveying device 12; the second lifting mechanism 15, the storage mechanism 16 and the first stopping mechanism 18 are all arranged at the incoming material pallet recovery station 11b; the first stopping mechanism 18 is used to stop the incoming material pallet 103 at the incoming material pallet recovery station 11b; the second lifting mechanism 15 drives the incoming material pallet 103 to disengage from the second conveying device 12 and move to the storage mechanism 16; the third lifting mechanism 17 is arranged at the material picking station 11c; the third lifting mechanism 17 drives the incoming material pallet 103 to disengage from the output end of the second conveying device 12.

[0055] In this embodiment, the first frame 11 has two parallel side walls, and the second conveying device 12 has two belts, which are respectively arranged at the same horizontal height on the two side walls and are parallel to each other. The first lifting mechanism 13, the second lifting mechanism 15, and the third lifting mechanism 17 are all arranged on the bottom plate of the first frame 11, and are located between the projections of the two belts on the bottom plate of the first frame 11. When the lifting mechanism is in a fully retracted state, the lifting mechanism is located below the belt, and the lifting mechanism can be lifted above the belt. The lifting mechanism can be a cylinder or a linear motor. The first clamping mechanism 14 has two cylinders, which are respectively arranged on two opposite side walls of the frame and above the input end of the belt. The free end of the cylinder is connected with a clamping grip, which can match the groove on the incoming material tray 103. The cylinder of the clamping mechanism can also be a linear motor. The stopping mechanism is a cylinder arranged below the belt, and the cylinder can lift the belt above to block the tray. Similarly, the lifting mechanism, clamping mechanism and stopping mechanism in the following can all refer to this embodiment.

[0056] Before the incoming material tray loading device 1 is started, in the incoming material tray placing station 11a, the incoming material trays 103 are stacked on the first lifting mechanism 13, and the first lifting mechanism 13 is in the jacking state. At this time, the incoming material tray 103 is located above the first clamping mechanism 14. After the incoming material tray loading device 1 is started, the first lifting mechanism 13 drives the incoming material tray 103 to descend to the first clamping mechanism 14, and the first clamping mechanism 14 clamps the remaining incoming material trays 103 except the bottommost incoming material tray 103. The first lifting mechanism 13 continues to descend, driving the bottommost incoming material tray 103 to the input end of the second conveying device 12. In this way, a single incoming material tray 103 is separated from the stacked incoming material trays 103. After separation, the second conveying device 12 conveys the incoming material tray 103 to the picking station 11c. The third lifting mechanism 17 jacks up, lifting the incoming material tray 103 above the belt. After the transfer device 5 removes the raw material in the incoming material tray 103, the third lifting mechanism 17 descends, putting the incoming material tray 103 back on the belt. At this time, the motor of the second conveying device 12 is reversed, and the belt moves in the reverse direction while driving the empty incoming material tray 103. At this time, the first stop mechanism 18 is started, stopping the empty incoming material tray 103 in the incoming material tray recycling station 11b. The second lifting mechanism 15 jacks up the empty incoming material tray 103 into the storage mechanism 16 located above the belt, realizing the recycling of the incoming material tray 103.

[0057] Further, please refer to Figure 5 , in an embodiment of the present invention, the feeding tray loading device 2 includes a second frame 21, a fourth lifting mechanism 22, a third conveying device 23, and a second clamping mechanism 24. The fourth lifting mechanism 22 is arranged inside the second frame 21, the third conveying device 23 is arranged on the second frame 21, and the second clamping mechanism 24 is arranged on the second frame 21 and located above the conveying device. A plurality of feeding trays 104 are stacked on the fourth lifting mechanism 22 and located above the second clamping mechanism 24. The second clamping mechanism 24 is used to clamp the feeding trays 104 stacked on the fourth lifting mechanism 22, and the fourth lifting mechanism 22 drives the feeding trays 104 to move to the input end of the third conveying device 23.

[0058] In this embodiment, the second frame 21 has two parallel side walls. The third conveying device 23 has two belts, and the two belts are respectively arranged at the same horizontal height on the two side walls and are parallel to each other. The fourth lifting mechanism 22 is arranged on the bottom plate of the second frame 21 and is located between the projections of the two belts on the bottom plate of the second frame 21. The fourth lifting mechanism 22 and the second clamping mechanism 24 can refer to the previous embodiment and will not be elaborated here.

[0059] Before the feeding tray loading device 2 is started, the feeding trays 104 are stacked on the fourth lifting mechanism 22, and the fourth lifting mechanism 22 is in the jacking state. At this time, the feeding trays 104 are located above the second clamping mechanism 24. After the feeding tray loading device 2 is started, the fourth lifting mechanism 22 drives the feeding trays 104 to descend to the second clamping mechanism 24. The second clamping mechanism 24 clamps the feeding trays 104 except the lowermost feeding tray 104. The fourth lifting mechanism 22 continues to descend, driving the lowermost feeding tray 104 to the input end of the second conveying device 12. In this way, a single feeding tray 104 is separated from the stacked feeding trays 104. After separation, the second conveying device 12 conveys the feeding tray 104 to the first conveying device 4.

[0060] Further, please refer to Figure 7 , in an embodiment of the present utility model, the first conveying device 4 is disposed through the carrying device 3.

The third clamping mechanism 32 is located above the first conveying device 4, the fifth lifting mechanism 31 is located below the first conveying device 4, and the second stopping mechanism 33 is used to stop the incoming tray 103 in the carrying device 3. The fifth lifting mechanism 31 drives the incoming tray 103 to disengage from the first conveying device 4 and approach the third clamping mechanism 32. The third clamping mechanism 32 is used to clamp the incoming tray 103.

[0061] To minimize space occupation as much as possible, a single production line is used for tray transportation in this embodiment, and it is necessary to consider that the transportation operations and transfer operations of various raw materials will not affect each other. Considering the functional characteristics, the overhead transfer method is adopted in this embodiment, that is, a carrying device 3 is arranged in the conveying device. An induction and identification device is provided on the carrying device 3. The induction device can be a photoelectric sensor or a pressure sensor, etc., and the identification device can be a barcode scanner 102 or a camera, etc. After the tray arrives, the sensor is triggered. After the identification device identifies the correct tray, the control system controls the second stopping mechanism 33 to stop the feeding tray in the carrying device 3. The fifth lifting mechanism 31 in the carrying device 3 jacks up the feeding tray 104, and the third clamping mechanism 32 located above the conveyor belt clamps the tray and suspends it. During the suspension process, the fifth lifting mechanism 31 descends below the conveyor belt, and the transfer device 5 transfers the raw materials in the incoming tray 103 to the suspended feeding tray 104. At this time, other empty trays or fully loaded trays can pass through below. The raw material transfer can be completed on a single production line, and at the same time, the transportation of other trays is satisfied.

[0062] Further, please refer to Figures 10 to 11, in an embodiment of the present utility model, the buffer device 6 has a buffer rack 61. A buffer bin 61a is formed inside the buffer rack 61. The buffer bin 61a has opposite buffer inlets 61a1 and buffer outlets 61a2. A gate mechanism 62 is provided at the buffer outlet 61a2. A fourth conveying device 63 is provided inside the buffer bin 61a. The input end of the fourth conveying device 63 is located at the buffer inlet 61a1, and the output end of the fourth conveying device 63 is located at the buffer outlet 61a2. In this embodiment, in order to increase the capacity of the buffer bin 61a, multiple layers of the fourth conveying device 63 are provided inside the buffer bin 61a. At least two driving motors are provided on the buffer rack 61. One of them is provided on the top wall of the buffer rack 61 and is used to drive the gate mechanism 62 to open or close the buffer outlet 61a2. The other is provided on the side wall of the buffer rack 61 and is used to drive the fourth conveying device 63.

[0063] The centralized buffering process of materials is a pre-step of the water washing process. The normal water washing process is centrifugal water washing with 6 stations or 8 stations, that is, 6 trays or 8 trays of materials are washed at a time. Usually, the time required for the washing process is longer than that of the feeding process. Without the buffer device 6, there will be a long downtime waiting time, and the overall washing speed is slow. After the buffer device 6 is set, the next batch of feeding can be continued while the previous batch of raw materials is being washed. After the previous batch of raw materials is washed, the gate mechanism 62 is opened, and the feeding tray that has been loaded is transported out of the buffer device 6 for the washing process. In this way, waiting is not required, and the overall washing efficiency is improved.

[0064] This embodiment provides a buffering structure for centralized processing of this process method, which can store 8 trays of materials at one time. The PCBA, the housing, and the lens are stored in different buffer bins respectively, and can also be used for buffering transfer processing in case of abnormalities to avoid downtime waiting.

[0066] In the present embodiment, the raw materials of the camera module to be cleaned include three types: shell, lens and PCBA. Therefore, the present embodiment is provided with three incoming tray loading devices 1: shell incoming tray loading device 1a, lens incoming tray loading device 1b and PCBA incoming tray loading device 1c; the present embodiment is also provided with three feeding tray loading devices 2: shell feeding tray loading device 2a, lens feeding tray loading device 2b and PCBA feeding tray loading device 2c; the present embodiment is also provided with three bearing devices 3: shell feeding tray bearing device 3a, lens feeding tray bearing device 3b and PCBA feeding tray bearing device 3c; the present embodiment is also provided with three cache bins 61a: shell cache bin, lens cache bin and PCBA cache bin.

In this embodiment, a first docking device 7 and a second docking device 8 are provided. The first docking device 7 serves to receive the shell feeding tray loading device 2a, the lens feeding tray loading device 2b and the PCBA feeding tray loading device 2c, and transfer the feeding trays to the first conveying device 4. The second docking device 8 is used to transfer the three feeding trays 104 on the first conveying device 4 to the corresponding buffer bin 61a.

[0067] It should be noted that the quantity settings of the incoming material tray loading device 1, the feeding tray loading device 2, and the buffer bin 61a in this embodiment are to meet the loading requirements of the camera module. When the types of raw materials increase or decrease, or when this equipment is used for loading other products, the quantity of the above devices can be adjusted according to requirements. In addition, the quantity of the transfer device 5 can also be adjusted.

[0068] Further, please refer to Figure 8 , in an embodiment of the present utility model, the first connection device 7 includes a first slide rail 71 and a first connection guide groove 72. The first connection guide groove 72 is slidably arranged on the first slide rail 71 and moves along the first slide rail 71. The three feeding tray loading devices 2 are all arranged on one side of the first slide rail 71. The first conveying device 4 is arranged on the side of the first slide rail 71 facing away from the three feeding tray loading devices 2. A fifth conveying device 73 is arranged on the side wall of the first connection guide groove 72. The output end of the fifth conveying device 73 is docked with the input end of the first conveying device 4. The first connection guide groove 72 moves along the first slide rail 71 so that the input end of the fifth conveying device 73 is respectively docked with the output ends of the three feeding tray loading devices 2.

[0069] In this embodiment, the first connection device 7 also has a servo drive module and an induction and identification device. The induction and identification device includes an inductor 101 and a barcode scanner 102. Driven by a servo motor, the first connection guide groove 72 is respectively docked with the housing feeding tray loading device 2a, the lens feeding tray loading device 2b, and the PCBA feeding tray loading device 2c according to the required signals. After the feeding tray 104 flows out, the fifth conveying device 73 starts to operate, and the feeding tray 104 is received into the first connection guide groove 72. When the inductor 101 on the first connection guide groove 72 senses that the tray is in place, it triggers a barcode scan to confirm the attributes of the feeding tray 104. After confirmation, the fifth conveying device 73 is started again, and the feeding tray 104 is conveyed to the input end of the first conveying device 4.

[0070] Further, please refer to Figure 9 , in an embodiment of the present utility model, the second connection device 8 includes a second slide rail 81, a second connection guide groove 82, and a sixth lifting mechanism 84. The second connection guide groove 82 is arranged on the sixth lifting mechanism 84. The sixth lifting mechanism 84 is slidably arranged on the second slide rail 81 and moves along the second slide rail 81. The buffer rack 61 is arranged on one side of the second slide rail 81. The first conveying device 4 is arranged on the side of the second slide rail 81 facing away from the buffer rack 61. A sixth conveying device 83 is arranged on the side wall of the second connection guide groove 82. The input end of the sixth conveying device 83 is docked with the output end of the first conveying device 4. The sixth lifting mechanism 84 moves along the second slide rail 81 so that the output end of the sixth conveying device 83 is respectively docked with the buffer inlets 61a1 of the three buffer bins 61a. The sixth lifting mechanism 84 drives the output end of the sixth conveying device 83 to be docked with the input end of the fourth conveying device 63.

[0071] In this embodiment, the second docking device 8 is responsible for transporting the feeding tray 104 at the output end of the first conveying device 4 to the buffer device 6. Like the first docking device 7, the second docking device 8 also has a servo drive module and an inductive identification device, which includes a sensor 101 and a barcode scanner 102. In order to increase the capacity of the buffer bin 61a, multiple layers of the fourth conveying device 63 are provided in the buffer bin 61a. Therefore, the second docking device 8 is also provided with a sixth lifting mechanism 84, which drives the second docking guide groove 82 to rise or fall to dock with the input end of the fourth conveying device 63 of each layer.

[0072] For further information, see Figures 12 to 13 In one embodiment of the utility model, the camera module feeding device 1000 also has a PCBA detection device 9, which includes a degree signal box 91, a MIPI board 92 and a detection fixture 93. A detection station 93a is formed on the detection fixture 93. The detection station 93a is provided with a detection pin 931 and a PCBA positioning pin 932. The detection fixture 93 is also provided with a fixing claw buckle 933 and a MIPI board wiring interface 934. The detection pin needle 931, the MIPI board wiring interface 934, the MIPI board 92 and the degree signal box 91 are electrically connected in sequence. The PCBA positioning pin 932 is used to realize the positioning of the PCBA at the detection station 93a, and the fixing claw buckle 933 is used to realize the fixation of the PCBA at the detection station 93a.

[0073] In this embodiment, the signal box 91 provides power to the product and processes electrical signals, and the MIPI board 92 and the corresponding circuit connect the signal box 91 with the detection fixture 93. There is a notch on the PCBA that matches the positioning pin. After the transfer device 5 picks up the product, it is placed on the detection station 93a on the test fixture and the notch is docked with the positioning pin. The fixed claw buckle 933 of the test fixture moves downward under the drive of the cylinder, pressing the PCBA against the detection fixture 93, and the test point on the PCBA is in contact with the detection pin 931 of the PCBA test fixture. At that time, the power is turned on to test whether the product is qualified. If it is qualified, the fixed claw buckle 933 is opened to release the PCBA, and the transfer device 5 moves over to pick up the material and places the PCBA in the feeding tray 104 in the carrying device 3. In order to facilitate the judgment of whether the PCBA is qualified, the PCBA detection device 9 also has a lamp, which is electrically connected to the signal box 91. When the PCBA is qualified, the lamp is lit.

[0074] Combined with the above embodiments, it should be noted that through the functional comparison of the materials, only the transfer of the materials for the lens and the housing is required, while the PCBA needs to perform a lighting test on the product to confirm the functional integrity of the PCBA incoming materials. Therefore, the transfer speed of the PCBA will definitely be slower than that of the lens and the housing. In order to achieve the balanced feeding of the three materials of the housing, the lens, and the PCBA, a balanced output is designed in the device. In one embodiment, the following settings are made: the lens incoming material tray feeding device 1b and the housing incoming material tray feeding device 1a are arranged adjacent to each other, the PCBA incoming material tray feeding device 1c is arranged separately, and the lens feeding tray carrying device 3b and the housing feeding tray carrying device 3a are arranged relatively far from the output end of the first conveying device 4, and the PCBA feeding tray carrying device 3c is arranged relatively close to the output end of the first conveying device 4. The housing and the lens share a transfer device 5 for transfer. At the same time, a PCBA detection device 9 and a PCBA feeding tray carrying device 3c are added, and a dedicated transfer device 5 is set to transfer the PCBA to improve the feeding speed of the PCBA. In summary, by relatively restricting the feeding speeds of the housing and the lens and increasing the feeding speed of the PCBA, the balanced feeding of the three raw materials of the housing, the lens, and the PCBA is achieved.

[0075] Please refer to Figures 7 to 9 , in an embodiment of the present invention, the camera module feeding device 1000 further has a plurality of induction and identification devices, and the plurality of induction and identification devices are respectively arranged on the first connection device 7, the carrying device 3, and the second connection device 8.

[0076] The induction and identification device includes an inductor 101 and a barcode scanner 102. The inductor 101 is used to sense whether the tray enters the corresponding working area, and the barcode scanner 102 is used to identify whether the tray entering the working area is correct. If it is incorrect, an alarm will be triggered to prevent the occurrence of material mixing.

[0077] The main reason for the occurrence of material mixing is that the feeding tray 104 is transported to the wrong position, for example, the housing feeding tray is transported into the PCBA feeding tray carrying device 3c. Therefore, a dual control of the structure and program is adopted for the transportation of the feeding tray 104 to prevent the wrong transportation of the tray. When the tray enters the working area of the induction and identification device, the inductor 101 will sense that the tray is in place and send a feedback signal to the motion control management system. The motion control management system will send a confirmation instruction to the barcode scanner 102 (for example, send P for the PCBA feeding tray, H for the housing feeding tray, and L for the lens feeding tray). The barcode scanner 102 scans and confirms the code engraved on the tray to confirm whether it is the same as the confirmation instruction sent by the motion control management system. If it is the same, the tray is correct; if it is different, the tray is incorrect and an alarm prompt is given accordingly to prevent the situation of material mixing.

[0078] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
