Description

TECHNICAL FIELD

Therefore, the production and assembly precision of camera modules are required to be higher and higher, so that the assembly technology of camera modules is constantly developing and improving, thereby fundamentally and revolutionarily changing the assembly technology of camera modules.

[0003] The traditional assembly method is to complete the feeding, assembly and testing operations by manual work, which undoubtedly greatly increases the labor cost, and the quality of assembly is not stable due to the uncertainty of manual operation. Therefore, some manufacturers in the industry use automatic assembly equipment to replace the traditional manual assembly method to automatically assemble the camera modules. However, the automatic assembly equipment of the camera modules still has the problems of low production efficiency, complex process flow, imperfect alignment system, and still over-reliance on manpower in each link, thereby leading to a relatively low degree of automation. Moreover, no manufacturer has integrated various process flows in the assembly process on a set of equipment to meet the actual needs of camera module products in production and testing. Therefore, how to design and provide a full-automatic assembly production line integrating automatic feeding, assembly and testing and other process flows to further improve the production efficiency and capacity has become a problem to be solved.

[0077] The present application provides a camera module full-automatic assembly production line for feeding and assembling a camera, a control assembly and a rear cover on a support to form a camera module, and performing a scoring test on the camera before the camera is assembled on the support, and performing a whole-machine test and automatic unloading on the camera module product after the camera module is assembled, so as to integrate all processes such as automatic feeding, automatic assembly and automatic testing together to meet the actual needs of camera module products in terms of assembly and testing.

[0078] The following takes the dual camera module used in the automobile controller as an example to illustrate the structure of the camera module full-automatic assembly production line in the present application. It can be understood that in other embodiments, the camera module full-automatic assembly production line in the present application is not limited to only assembling the dual camera module used in the automobile controller, but also can be used for assembling the camera module used in any intelligent terminal product (such as smart wear, smart home, smart phone or vehicle event data recorder, etc.), which is not limited herein.

[0079] Referring to Figure 1 , Figure 1 The overall top view structure of the camera module full-automatic assembly production line 10 provided by an embodiment of the present application is shown. The camera module full-automatic assembly production line 10 provided by an embodiment of the present application is in L shape when viewed from the top, and includes a camera testing work station 100, a first assembly work station 200, a first locking work station 300, a second assembly work station 400, a second locking work station 500 and a whole machine testing work station 600 arranged in sequence along a transmission direction of the L shape. The camera module includes a support, a camera, a control assembly and a back cover assembled on the support. The camera testing work station 100 is used for automatically feeding the camera and testing the quality of the camera. The first assembly work station 200 is used for automatically feeding the support and assembling the camera on the support. The first locking work station 300 is used for locking the camera and the support. The second assembly work station 400 is used for manually assembling the control assembly on the support and detecting the assembly quality of the control assembly on the support after assembly. The second locking work station 500 is used for assembling the back cover on the support with the camera and the control assembly and locking the back cover and the support with the camera and the control assembly to form the camera module. The whole machine testing work station 600 is used for testing the camera module and outputting the camera module.

[0080] It can be understood that the above-mentioned camera module full-automatic assembly production line 10 can also be arranged in a straight line or in any other way, which is not limited herein. However, the arrangement in L shape makes the overall layout of the camera module full-automatic assembly production line 10 not occupy a large space.

[0081] In one embodiment, referring to Figure 2 and Figure 3The camera test work station 100 comprises a first mechanical arm 110 and a first feeding unit 120, a power-on test unit 130 and a first discharging unit 140 arranged on the side of the first mechanical arm 110. The first feeding unit 120 is used for automatically feeding the camera. The power-on test unit 130 is used for power-on test of the camera to obtain the quality score of the camera. The first discharging unit 140 is used for conveying the camera to the first assembly work station 200. The first mechanical arm 110 is used for grabbing the camera from the first feeding unit 120 to the power-on test unit 130, and is used for grabbing the camera from the power-on test unit 130 to the first discharging unit 140 after the power-on test is completed.

[0082] Specifically, as shown in Figure 4 In one embodiment, the first feeding unit 120 is a stack structure comprising a first lifting module 121, a stock bin assembly 122 and a discharging assembly 123. The stock bin assembly 122 is liftable mounted on the first lifting module 121, and has a plurality of stacked trays 1221 in the stock bin assembly 122, each of which is used for temporarily storing the camera. The discharging assembly 123 is arranged on one side of the stock bin assembly 122 and is used for pulling out the tray 1221 loaded with the camera from the stock bin assembly 122.

[0083] In this way, when the operator manually feeds a plurality of trays 1221 loaded with cameras into the stock bin assembly 122 to complete manual feeding, the discharging assembly 123 can pull out the trays 1221 loaded with cameras layer by layer to realize automatic feeding layer by layer when the stock bin assembly 122 intermittently moves up or down relative to the first lifting module 121. Through the above arrangement, the first feeding unit 120 can automatically discharge without manual discharge. Since the trays 1221 are discharged layer by layer instead of all at once, the operator can fill new cameras at a longer interval after the cameras are loaded into the stock bin assembly 122 at one time, without frequent feeding, thereby reducing the labor intensity of the operator.

[0084] It is worth noting that since the entire device has a certain degree of vibration when working, in order to prevent the trays 1221 from sliding out of the stock bin assembly 122 under the action of vibration and causing safety accidents, as a preferred improved embodiment, as shown in Figure 4 and Figure 5As shown, the hopper assembly 122 further comprises a hopper 1222 and a shutter 1223 movably arranged outside the hopper 1222, the hopper 1222 has a plurality of vertically spaced bearing gaps 1224, and each tray 1221 is movably connected to the hopper 1222 and accommodated in a corresponding bearing gap 1224. The shutter 1223 is capable of vertical lifting movement relative to the hopper 1222, and the shutter 1223 is zigzag-shaped so that the shutter 1223 has a plurality of vertically spaced through-slots 1223a.

[0085] When the shutter 1223 is vertically lifted relative to the hopper 1222, the plurality of through-slots 1223a of the shutter 1223 can be one-to-one corresponding or misaligned with the corresponding bearing gaps 1224 of the hopper 1222, when the through-slots 1223a of the shutter 1223 are one-to-one corresponding with the corresponding bearing gaps 1224, the hopper assembly 122 is in an open state, the tray 1221 loaded with the camera can be pushed into the bearing gap 1224 of the hopper 1222 by the operator, and the tray 1221 can be pulled out of the bearing gap 1224 by the outfeed assembly 123 for the first robot 110 to take the tray 1221; when the through-slots 1223a of the shutter 1223 are misaligned with the corresponding bearing gaps 1224, the hopper assembly 122 is in a closed state, the tray 1221 in the hopper assembly 122 is blocked by the shutter 1223 and cannot slide out of the bearing gap 1224, so that safety accidents caused by accidental sliding of the tray 1221 out of the hopper assembly 122 can be avoided.

[0086] Further, in an embodiment, please continue to refer to Figure 1 to Figure 3 The power-on test unit 130 comprises a power-on module 131 and a first test module 132 arranged adjacent to each other, the power-on module 131 is used to power on the camera when the camera is loaded on the power-on module 131, and the camera is connected to the first test module 132, so that the first test module 132 can perform a scoring test on the camera. Preferably, as shown in Figure 6 The power-on module 131 comprises a base 1311 and a power-on assembly 1312, the opposite ends of the power-on assembly 1312 are rotatably connected to the base 1311, and one end of the power-on assembly 1312 is rotatably connected to a driving source such as a motor, and the power-on assembly 1312 is capable of rotating around an axis under the driving of the motor, so that the camera loaded on the power-on assembly 1312 can be connected to the first test module 132.

[0087] In order to improve the test efficiency, preferably, please continue to refer to Figure 6The first test module 132 is loaded on the two power-on assemblies 1312, and the two cameras on the two power-on assemblies 1312 can alternately connect the first test module 132 for testing at the test station of the first test module 132, thereby improving the testing efficiency.

[0088] In one embodiment, as shown in Figure 7 The first unloading unit 140 includes, in sequence along the conveying direction, a first transfer module 141, a first orthogonal transfer module 142, a second transfer module 143, and a temporary storage disc 144 arranged between the first orthogonal transfer module 142 and the second transfer module 143. The first transfer module 141 is arranged along the conveying direction and used to transfer the cameras that have completed the power-on test from the head end of the first transfer module 141 to the tail end of the first transfer module 141. The first orthogonal transfer module 142 is a three-axis module structure, and the first orthogonal transfer module 142 is provided with first clamps 1421. In one embodiment, as shown in Figure 8 The cameras to be assembled are double-camera modules, so that the first clamps 1421 are two, and the two first clamps 1421 can be driven by the first orthogonal transfer module 142 to grab the cameras from the tail end of the first transfer module 141 to the temporary storage disc 144. The cameras are classified and arranged on the temporary storage disc 144, and the cameras with the same score are placed together, so that the two first clamps 1421 can easily grab the cameras with the same score together to the second transfer module 143. The second transfer module 143 is also arranged along the conveying direction and used to deliver the two cameras with the same score to the first assembly station 200.

[0089] It should be noted that the number of first clamps 1421 depends on the product type of the camera module to be assembled. When the camera module to be assembled is a three-camera module or a multi-camera module, the number of first clamps 1421 can be three or more. When the camera module to be assembled is a single-camera module, the number of first clamps 1421 is one, and the temporary storage disc 144 can not be arranged. Only one of the first transfer module 141 and the second transfer module 143 needs to be arranged, and the first transfer module 141 or the second transfer module 143 can extend to the first assembly station 200 along the conveying direction. The first unloading unit 140 can also have other structures, such as the stacking structure of the first feeding unit 120. The above are not particularly limited.

[0090] As an improvement to the above embodiment, as shown in Figure 9 The camera testing work station 100 further comprises a position correction device 150, which is arranged on the periphery of the first robot 110 and between the first feeding unit 120 and the power-on testing unit 130. The position correction device 150 has a base 151 and a correction block 152 movably connected to the base 151. When the camera is grabbed by the first robot 110 from the tray 1221 of the first feeding unit 120 to the base 151, the correction block 152 can reciprocate relative to the base 151 to correct the position of the camera placed in a skew manner.

[0091] Further, when the camera is assembled on the bracket, the lens of the camera is arranged upward. However, when the camera is grabbed by the first robot 110 after the power-on testing is completed by the power-on testing unit 130, the lens of the camera cannot be guaranteed to be arranged upward. In order to solve this problem, as shown in Figure 10 The camera testing work station 100 further comprises a first turnover device 160, which is arranged upstream of the first transfer module 141 and downstream of the power-on testing unit 130. The first turnover device 160 has a third gripper 161 connected to a rotary cylinder, so that the third gripper 161 can grab the camera 70 and turn it by 180°, thereby ensuring that the lens of the camera 70 is always arranged upward before being grabbed to the first transfer module 141.

[0092] In addition, please continue to refer to Figure 2 The first robot 110 is further provided with a first NG storage unit 170 on the periphery thereof. When the power-on module 131 performs power-on testing on the camera and obtains a quality score of the camera as unqualified, the first robot 110 can grab the camera with the unqualified quality score and store it on the first NG storage unit 170 for further processing.

[0093] Please refer to Figure 11 In one embodiment, the first assembly work station 200 comprises a second robot 210, a second feeding unit 220 and a second discharging unit 230. The output end of the camera testing work station 100 (i.e. the end of the second transfer module 143), the second feeding unit 220 and the second discharging unit 230 are arranged on the periphery of the second robot 210. The second feeding unit 220 is used for automatically feeding the bracket; the second robot 210 is used for grabbing the bracket to the second discharging unit 230 and assembling the camera conveyed to the end of the second transfer module 143 to the bracket temporarily stored in the second discharging unit 230.

[0094] In Figure 11In the embodiment shown in FIG. 2, the second feeding unit 220 has two, and the two second feeding units 220 are arranged side by side, for automatically feeding supports of two different structures, so that the second robot 210 can selectively pick up supports of one structure from the two second feeding units 220 to the second discharging unit 230, so as to selectively assemble camera module products of two different structures. As shown in FIG. 2, each second feeding unit 220 has the same structure as the first feeding unit 120, which is also a stacked structure, and thus will not be described here. Figure 11

[0095] In some embodiments, referring to FIG. 2, the second discharging unit 230 includes a second lifting module 231 and a carrying module 232 movably arranged on the second lifting module 231. The carrying module 232 is used to carry the supports picked up by the second robot 210 from the second feeding unit 220, and can be lifted by the second lifting module 231 and can also convey the supports loaded with cameras to the first locking station 300 along the conveying direction. Figure 12

[0096] Since the camera and the support are not symmetrical structures, and the camera is not symmetrically assembled on the support when assembled on the support, the camera and the support must be assembled in a specific direction. In order to avoid the second robot 210 picking up the support in the opposite direction when picking up the support, causing the camera to be assembled in the wrong direction on the support, preferably, as shown in FIG. 2, the second robot 210 has two second grippers 211, one of which is used to pick up the camera 70, and the other is used to pick up the support 80. The second gripper 211 for picking up the support 80 is provided with a sensing element 212, which is used to determine whether the direction of the support 80 picked up by the second gripper 211 is correct when the second gripper 211 picks up the support 80. For example, as shown in the embodiment of FIG. 2, the sensing element 212 is in the form of a needle, and the sensing element 212 is arranged in spaced relation with the second gripper 211. When the second gripper 211 picks up the support 80 in the opposite direction, the end of the sensing element 212 will abut against the support 80, and an alarm signal will be sent, so that the operator can know that the direction of the second gripper 211 picking up the support 80 is the wrong direction, and thus the second robot 210 can adjust the direction of picking up the support 80 in time. Figure 13 Figure 13

[0097] It can be understood that the way the second robot 210 adjusts the direction of picking up the support 80 is not limited, which can be manually removed from the second gripper 211 for adjustment, or as shown in the embodiment of FIG. 2, the second robot 210 has a second lifting module 231, and the second gripper 211 is movably arranged on the second lifting module 231. When the second gripper 211 picks up the support 80 in the opposite direction, the second lifting module 231 can be controlled to move the second gripper 211 to the position of the carrying module 232, and the carrying module 232 can be controlled to move the support 80 to the position of the second gripper 211, so that the second gripper 211 can pick up the support 80 again in the correct direction. Figure 14 ​​​​As shown, one adjusting tool 240 for temporarily storing the support 80 is arranged on the two second upper feeding units 220, and the support 80 is temporarily placed in the adjusting tool 240 by the second clamping jaw 211, and then the second clamping jaw 211 is rotated by 180° to re-grasp the support 80 in the correct direction, or the adjusting tool 240 is rotated by 180° after the support 80 is temporarily placed in the adjusting tool 240, and the second clamping jaw 211 does not need to be rotated, so that the support 80 can also be re-grasped in the correct direction.

[0098] Referring to Figure 15 In one embodiment, the first locking station 300 comprises a first locking unit 310 and a third transfer module 320 arranged along the conveying direction through the first locking unit 310. The first locking unit 310 has a first locking accessory 311 capable of freely moving in a three-dimensional space, which can be a screwdriver or the like tool for locking the support and the camera by screwing. The first end of the third transfer module 320 is connected to the second feeding unit 230 of the first assembly station 200, and the last end of the third transfer module 320 is connected to the second assembly station 400.

[0099] In one embodiment, the first locking unit 310 has a first locking position 312, and the first locking unit 310 comprises a three-axis module, and the first locking accessory 311 is installed on the three-axis module. When the third transfer module 320 carries the support and the camera loaded on the support to the first locking position 312, the first locking accessory 311 can freely move in a three-dimensional space in the front-back, left-right and up-down directions under the driving of the three-axis module, so as to screw the screws in the screw holes at different positions of the camera and the support to complete the locking of the camera and the support.

[0100] In order to make the position of the screw locking more accurate and ensure the locking quality, preferably, as shown, Figure 16 The first locking unit 310 also has a positioning assembly 313, which is also installed on the three-axis module and comprises a positioning needle 3131 and a visual camera 3132. Before the first locking accessory 311 locks the camera and the support, the visual camera 3132 first takes a photo of the position to be screwed, and sends the photo information to the control system, and the control system sends a control instruction to control the three-axis module to guide the positioning needle 3131 to move, so that the screw hole to be screwed on the camera and the support are centered with each other, so as to ensure that the position of the locking by the first locking accessory 311 is more accurate.

[0101] More preferably, in order to prevent the support from moving arbitrarily on the third transfer module 320 when the first locking accessory 311 locks the camera and the support, as shown, Figure 17As shown, the first locking station 300 further comprises a pressing device 330 arranged at the first locking position 312, the pressing device 330 comprises a cover plate 331 and a lifting mechanism 332, the lifting mechanism 332 is capable of lifting the bracket assembled with the camera upward when the bracket assembled with the camera passes through the first locking position 312, so that the camera and the bracket are abutted against the cover plate 332 when lifted to a certain height, so that the bracket and the camera are fixed at the first locking position 312 and are convenient to be locked by the first locking member 311.

[0102] Preferably, in order to prevent the bracket assembled with the camera from being abutted against the cover plate 332 with excessive force, as shown, Figure 18 The pressing device 330 further comprises a pre-pressing assembly 333 arranged at the bottom side of the cover plate 331, the pre-pressing assembly 333 comprises a fixed part 3331 and a movable part 3332, the fixed part 3331 is fixedly installed at the bottom side of the cover plate 331, the fixed part 3331 and the movable part 3332 are connected with each other through an elastic element such as a spring, and the movable part 3332 is used for abutting against the bracket assembled with the camera, so that the bracket assembled with the camera is not abutted against the cover plate 332 with excessive force when abutted against the cover plate 332, thereby avoiding the product from being damaged.

[0103] Further, in order to prevent the bracket assembled with the camera from being abutted at a position between the cover plate 332 and the lifting mechanism 332 before being locked by the first locking member 311, as shown, Figure 19 The pressing device 330 further comprises a plurality of position correcting assemblies 334, the plurality of position correcting assemblies 334 are also arranged at the bottom side of the cover plate 331, as shown, Figure 20 Each position correcting assembly 334 comprises a driving part 3341 and two clamping parts 3342 movably connected to the driving part 3341, the two clamping parts 3342 are capable of being close to each other to clamp the bracket assembled with the camera, and are capable of correcting the position of the bracket under the driving of the driving part 3341, so that the screw hole on the bracket is centered with the through hole 3311 on the cover plate 331, thereby enabling the screw to be smoothly locked to the camera and the bracket to fix and connect the camera and the bracket to each other.

[0104] Thus, in the process of locking, first, the bracket assembled with the camera is lifted upward by the lifting mechanism 332, so that the camera and the bracket are pre-pressed by the pre-pressing assembly 333 when lifted to a certain height, and the product is abutted against the cover plate 332 with an elastic force, then the position of the product is corrected by the position correcting assembly 334, and finally the screw is locked to the camera and the bracket by the first locking member 311.

[0105] Referring to Figure 21In one embodiment, the second assembly station 400 comprises a fourth transfer module 410 and a detection module 420. The first end of the fourth transfer module 410 is connected to the last end of the third transfer module 320 in the first locking station 300, and the last end of the fourth transfer module 410 is connected to the second locking station 500. The detection module 420 is arranged above the fourth transfer module 410. Preferably, a lifting mechanism 314 is also arranged below the fourth transfer module 410. When the support transported by the fourth transfer module 410 passes below the detection module 420, an operator can operate the operation button on the second assembly station 400 to make the lifting mechanism 314 lift the support assembled with the control components upward, so that the support can be stopped below the detection module 420. The operator can assemble the control components such as the flexible circuit board and the circuit substrate to the support by manual assembly. Specifically, the two ends of the flexible circuit board are connected to the circuit substrate and the camera, respectively. Then, the flexible circuit board and the circuit substrate are placed in the support as a whole, and the RFID writing is completed to make the product have a unique identity identification. Then, the detection module 420 detects the assembly quality. After the detection is completed, the operator can operate the operation button on the second assembly station 400 to make the lifting mechanism 314 descend, and the fourth transfer module 410 transports the support assembled with the control components to the next station.

[0106] Referring to Figure 22 In one embodiment, the second locking station 500 comprises a second orthogonal transfer module 510, a second locking unit 520 and a fifth transfer module 530. The second orthogonal transfer module 510 and the second locking unit 520 are arranged in series in the transmission direction, and the second orthogonal transfer module 510 is located upstream of the second locking unit 520. The fifth transfer module 530 is arranged in the transmission direction through the second orthogonal transfer module 510 and the second locking unit 520. The first end of the fifth transfer module 530 is connected to the last end of the fourth transfer module 410 in the second assembly station 400, and the last end of the fifth transfer module 530 is connected to the whole machine test station 600. The second orthogonal transfer module 510 is used to assemble the rear cover to the support, and the second locking unit 520 is used to lock the rear cover and the support.

[0107] The structure of the second orthogonal transfer module 510 is similar to that of the first orthogonal transfer module 142. The second orthogonal transfer module 510 can be a structure in which clamps are installed on a three-axis module, or a structure in which clamps are installed on a two-axis module. When the structure of the second orthogonal transfer module 510 is a structure in which clamps are installed on a three-axis module, the clamps can move in the front-rear, left-right, and up-down directions in another three-dimensional space when the bracket assembled with the camera and the control assembly passes through the second orthogonal transfer module 510 driven by the fifth transfer module 530. When the structure of the second orthogonal transfer module 510 is a structure in which clamps are installed on a two-axis module, the clamps can move in the left-right and up-down directions to grab the rear cover and assemble the rear cover on the bracket. The second locking unit 520 is used to lock the rear cover and the bracket with each other when the bracket assembled with the camera, the control assembly, and the rear cover passes through the second locking unit 520, thereby forming a product of the camera module. The structure of the second locking unit 520 is the same as that of the first locking unit 310, and a jacking mechanism 314 is arranged below the second locking unit 520. The second locking unit 520 is provided with a second locking station 521 below, and the second locking station 521 is also provided with a jacking mechanism 314 and a cover plate 313, which have the same functions as the first locking station 300, and will not be described again here.

[0108] In a preferred embodiment, the second locking unit 520 has two second locking units, and correspondingly, the second locking station 521 also has two second locking stations. Above each second locking station 521, a corresponding second locking unit is arranged, so that two brackets assembled with the rear cover transported on the fifth transfer module 530 can be screwed at the same time to improve the locking efficiency and reduce the waiting time. It can be understood that the number of second locking units and second locking stations 521 is not limited and can be multiple, which can be set as needed. In addition, a stacking type feeding unit for automatically feeding the rear cover can be arranged upstream of the second orthogonal transfer module 510, which can be configured as needed and is not particularly limited here.

[0109] Referring to Figure 23 and Figure 24 In an embodiment, the whole machine test station 600 includes a third mechanical hand 610, a sixth transfer module 620 arranged on the side of the third mechanical hand 610, a second test module 630, and a third discharging unit 640. The first end of the sixth transfer module 620 is connected to the last end of the fifth transfer module 530 in the second locking station 500 and is arranged in the transmission direction. The third mechanical hand 610 is used to grab the assembled camera module to the second test module 630 for whole machine test, and is used to grab the camera module to the third discharging unit 640 for discharging output after the whole machine test is completed.

[0110] Specifically, as Figure 25As shown, the second testing module 630 comprises a testing platform 631 and probes 632 movably connected on the testing platform 631, the probes 632 are connected to driving sources such as air cylinders and can move on the testing platform 631 under the driving of the air cylinders to be able to abut against the camera module products for testing. Preferably, a press head 633 can also be provided on the testing platform 631, the press head 633 is also connected to driving sources such as air cylinders and can be lifted up and down under the driving of the air cylinders to abut against the camera module to prevent the camera module from moving randomly on the testing platform 631 to affect the test results.

[0111] The third unloading unit 640 has the same structure as the first feeding unit 120 and the second feeding unit 220, which is also a stacked structure and also has a liftable hopper assembly that can carry the tested qualified products for unloading output, which will not be described here.

[0112] Please continue to refer to Figure 23 and Figure 24 In a more preferred embodiment, the whole machine testing work station 600 further comprises a marking unit 650 provided on the side of the third robot 610, the marking unit 650 can mark the camera module before unloading output by laser marking or labeling, so that each camera module product can be distinguished from each other, therefore the marking unit 650 comprises one or both of a laser marking module 651 and a labeling module 652.

[0113] Specifically, the laser marking module 651 can be provided beside the second testing module 630 and located upstream of the second testing module 630 in the direction around the third robot 610, so that the camera module grabbed by the third robot 610 can be laser marked before whole machine testing. As shown, Figure 26 As shown, the laser marking module 651 comprises a laser device 6511 and a carrying platform 6512 movably connected to the laser device 6511, the carrying platform 6512 can move into or out of the laser device 6511 relative to the laser device 6511, so as to be able to send the camera module grabbed by the third robot 610 into the laser device 6511 for laser marking, and output out of the laser device 6511 after laser marking is completed.

[0114] The labeling module 652 can also be arranged beside the second testing module 630 and downstream of the second testing module 630 in the direction surrounding the third mechanical arm 610. Specifically, the labeling module 652 comprises a label printer 6521 and a labeling platform 6522 arranged adjacently, and the third mechanical arm 610 is provided with a suction element (not shown in the figure) for sucking labels. The label printer 6521 is used for printing labels, and the labeling platform 6522 is used for carrying a camera module. Thus, the third mechanical arm 610 can grasp the camera module and place it on the labeling platform 6522, and then the third mechanical arm 610 can suck labels from the label printer 6521 and paste the labels on the camera module.

[0115] Since the surface to be labeled of the camera module is not necessarily upward when the third mechanical arm 610 grasps the camera module, as an improved embodiment, referring to Figure 27 , the labeling module 652 comprises a second turnover device 6523, which has a fourth gripper 6523a connected to a rotary cylinder, so that the fourth gripper 6523a can be turned over under the drive of the rotary cylinder, so that when the surface to be labeled of the camera module is downward, the fourth gripper 6523a can be clamped and turned over by 180°, so that the surface to be labeled can be upward, thereby facilitating the third mechanical arm 610 to paste labels on the surface to be labeled of the camera module.

[0116] Preferably, referring to Figure 23 , in order to expand the grasping range of the third mechanical arm 610, the third mechanical arm 610 is installed on a second linear module 660 extending in the conveying direction and can move on the second linear module 660, so as to expand the grasping range of the third mechanical arm 610.

[0117] In addition, the whole machine testing work station 600 is also provided with a second NG storage unit 670 on the side of the third mechanical arm 610, and the second NG storage unit 670 is arranged beside the third blanking unit 640, i.e. upstream of the third blanking unit 640 in the direction surrounding the third mechanical arm 610. After the second testing module 630 completes the whole machine testing of the camera module, the third mechanical arm 610 can grasp the products that do not meet the whole machine testing or laser marking and place them in the second NG storage unit 670 to wait for the next processing.

[0118] More preferably, in order to recycle the carrier for carrying the pre-assembly product or post-assembly product after the camera module is discharged by the third discharging unit 640, the camera module full-automatic assembly production line 10 further comprises a carrier recycling conveying line, which is arranged in the whole machine testing station 600, the second locking station 500, the second assembly station 400, the first locking station 300 and the first assembly station 200, and the first end of the carrier recycling conveying line is connected to the third discharging unit 640 in the whole machine testing station 600, and the last end of the carrier recycling conveying line is connected to the second discharging unit 230 in the first assembly station 200.

[0119] Specifically, referring to Figure 15 、 Figure 21 、 Figure 22 and Figure 24 , the carrier recycling conveying line comprises a first sub-conveying line 680, a second sub-conveying line 540, a third sub-conveying line 430 and a fourth sub-conveying line 340 connected in sequence, wherein, as shown in Figure 24 , the first sub-conveying line 680 is arranged in the whole machine testing station 600 and arranged in parallel with the sixth transfer module 620, as shown in Figure 19 , the second sub-conveying line 540 is arranged in the second locking station 500 and arranged in parallel with the fifth transfer module 530, as shown in Figure 18 , the third sub-conveying line 430 is arranged in the second assembly station 400 and arranged in parallel with the fourth transfer module 410, and the fourth sub-conveying line 340 is arranged in the first locking station 300 and arranged in parallel with the third transfer module 320, the first end of the carrier recycling conveying line is the first end of the first sub-conveying line 680, and the last end of the carrier recycling conveying line is the last end of the fourth sub-conveying line 340. It can be understood that the parallel arrangement can be parallel arrangement in the vertical direction or parallel arrangement in the horizontal direction, without particular limitation.

[0120] Therefore, when the camera module is discharged in the whole machine testing station 600, the empty carrier can be moved to the position of the second discharging unit 230 of the first assembly station 200 along the carrier recycling conveying line, so as to be recycled again.

[0121] Therefore, the camera module full-automatic assembly production line 10 provided by the application integrates all the process flows such as automatic feeding, automatic assembly, automatic testing and automatic marking together, meets the actual needs of camera module products in production and testing, and has less dependence on manpower in the assembly and testing process, so that the degree of automation is higher, and the production efficiency and capacity of the camera module products are further improved.

[0122] Finally, it should be noted that the technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to be within the scope of the present disclosure.

[0123] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
