[0079] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0080] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0081] In order to further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following detailed description of this application is made in conjunction with the accompanying drawings and preferred implementation methods.

[0082] Please also refer to Figure 1 and Figure 2 The loading and unloading equipment 100 provided in the embodiment of the present application includes a transfer device 1 and a material picking device 3. The loading and unloading equipment 100 is used to transfer the material 7 into the protective shell 5. The transfer device 1 includes a transfer mechanism 11, a suction mechanism 13, a positioning mechanism 15, and a loading mechanism 17. The material picking device 3 is arranged on one side of the transfer device 1. The material picking device 3 includes a manipulator 31 and a material tray 33. The material tray 33 is used to support the protective shell 5 and the protective shell 5 with the material 7 placed thereon.

[0083] In this embodiment, material 7 is a rear camera module. Material 7 includes a sub-lens 71 and a flexible printed circuit board 73. The sub-lens 71 is electrically connected to the flexible printed circuit board 73, and the flexible printed circuit board 73 is attached to the side of the sub-lens 71 opposite to the side that performs the camera function. Material 7 may include three sub-lenses 71. Material 7 may also include one, two, or more sub-lenses 71. In other embodiments, material 7 may also be other components of an electronic device, such as a chip, battery, flexible printed circuit board, and lens, and this application does not limit this.

[0084] Specifically, when the material 7 is placed in the protective shell 5, the material 7 enters the protective shell 5 in the direction in which the sub-lens 71 approaches the protective shell 5, so that the side of the sub-lens 71 used to realize the camera function is wrapped by the protective shell 5. In this embodiment, the size and shape of the protective shell 5 are adapted to the material 7, thereby preventing the material 7 from moving relative to the protective shell 5 when placed in the protective shell 5, causing damage to the sub-lens 71. In other embodiments, the protective shell 5 and the material 7 may also have size differences or shape differences, which is not limited in this application. The number of sub-lenses 71 and the arrangement position of each sub-lens 71 on the flexible circuit board 73 may affect the size and shape of the protective shell 5. The material of the protective shell 5 includes but is not limited to any one of silicone, plastic, metal, leather and glass. In other embodiments, when the material 7 is an electronic device chip, the side of the material 7 soldered with solder needs to be placed in the protective shell 5 to prevent damage to the solder. The size and shape of the electronic device chip affect the shape and material of the protective shell 5, which is not limited in this application.

[0085] Please also refer to Figure 3 and Figure 4The transfer mechanism 11 includes a carrier plate 111 and a fixing module 113. The carrier plate 111 is used to carry the protective shell 5.

The material of the carrier plate 111 can be metal, plastic, wood or other materials. The carrier plate 111 includes a first plate body 1111 and a second plate body 1113. The second plate body 1113 is arranged on a side surface of the first plate body 1111. The second plate body 1113 is used to define a preset position together with the fixing module 113. Specifically, a positioning groove 1115 is opened on the second plate body 1113 by turning, milling, drilling or boring. The first side wall 1115a of the positioning groove 1115 in the first direction X is used to block the protective shell 5, thereby defining a preset position in the first direction X together with the fixing module 113. The second sidewall 1115b of the positioning groove 1115 in the second direction Y is used to block the protective shell 5 in the second direction Y, thereby defining a preset position in the second direction Y together with the fixing module 113. The first direction X is perpendicular to the second direction Y. In this embodiment, the first plate 1111 is fixed to the second plate 1113 via an adhesive. In other embodiments, the first plate 1111 and the second plate 1113 can be fixed by welding. In addition, the first plate 1111 and the second plate 1113 can also be integrally formed, which is not limited in this application.

[0086] The fixing module 113 includes a first fixing module 1131 and a second fixing module 1133. The first fixing module 1131 includes a first fixing block 1131a, which is configured to move along a first direction X to abut against the protective shell 5. The first fixing module 1131 also includes a first driving module 1131b, which is movably connected to the first driving module 1131b and configured to drive the first fixing block 1131a to move along the first direction X. When the first fixing block 1131a contacts the protective shell 5 placed in the positioning slot 1115 during movement, the first driving module 1131b pauses. In this embodiment, the first fixed module 1131 includes two first fixed blocks 1131a, and two positioning slots 1115 are correspondingly defined on the second plate 1113. The first drive module 1131b is a clamping cylinder that drives the two first fixed blocks 1131a to move simultaneously along the first direction X. In other embodiments, the first fixed module 1131 may also include one, three, or more first fixed blocks 1131a, and the first drive module 1131b may also be manually or motor-driven to move all first fixed blocks 1131a along the first direction X. This is not a limitation of the present application. The second fixed module 1133 includes a second fixed block 1133a, which is used to move along the second direction Y to abut the protective shell 5, with the first direction X being perpendicular to the second direction Y. The second fixed module 1133 also includes a second drive module 1133b. When the second fixed block 1133a touches the protective shell 5 placed on the positioning slot 1115 during movement, the second drive module 1133b pauses. The second fixed block 1133a is movably connected to the second drive module 1133b, and the second drive module 1133b is used to drive the second fixed block 1133a to move along the second direction Y. In this embodiment, the second fixed module 1133 includes two second fixed blocks 1133a, and the second plate 1113 has two corresponding positioning slots 1115. The second drive module 1133b is a clamping cylinder. In other embodiments, the first direction X may not be perpendicular to the second direction Y. The second fixed module 1133 may also include one, three, or more second fixed blocks 1133a. The second drive module 1133b may also be manually or motor-driven to move all second fixed blocks 1133a along the second direction Y. This is not limited to this application.

[0087] Please also refer to Figure 5 and Figure 6, the suction mechanism 13 is arranged on one side of the transfer mechanism 11 for carrying the protective shell 5, and the suction mechanism 13 is used to suck the material 7, and is used to place the material 7 into the protective shell 5 fixed at a preset position. The suction mechanism 13 includes a suction cup 131 and a bracket 133, the suction cup 131 is accommodated in the bracket 133, and the suction cup 131 is used to suck the material 7. The bracket 133 includes a plate body 1331 and a receiving hole 1333, and the suction cup 131 is accommodated in the receiving hole 1333. In this embodiment, the suction cup 131 is connected to an end of the air pipe (not shown) away from the plate body 1331, and the process of the suction cup 131 sucking the material 7 is controlled by controlling the flow of airflow. In other embodiments, the suction cup 131 can also absorb the material 7 by magnetic attraction, which is not limited in this application.

[0088] The plate 1331 includes a joining surface A. When the suction mechanism 13 sucks the material 7, the joining surface A joins with the material 7. The joining surface A includes multiple joining areas 13311. The number of joining areas 13311 matches the number of sub-lenses 71 of the material 7. In this embodiment, the joining surface A includes three joining areas 13311, and the three joining areas 13311 are adapted to the three sub-lenses 71. In other embodiments, the joining surface A may also include two, four, or more joining areas 13311, which is not limited by this application. Specifically, the thickness of the plate 1331 corresponding to each joining area 13311 is different. The joining areas 13311 can be opened on the plate 1331 by turning, milling, drilling, or boring. In this embodiment, by providing joining areas 13311 with different plate 1331 thicknesses, the suction mechanism 13 can more firmly suck the material 7, which is conducive to enhancing the suction strength. In this embodiment, the plate 1331 includes three bonding areas 13311: a first bonding area 1331a, a second bonding area 1331b, and a third bonding area 1331c. The thickness difference between the first bonding area 1331a and the second bonding area 1331b is in the range of 0.40-0.55 mm, and the thickness difference between the second bonding area 1331b and the third bonding area 1331c is in the range of 0.10-0.25 mm. In other embodiments, the thickness difference between adjacent bonding areas 13311 may also be in the range of 0.1 mm-1 mm, which is not limited in this application.

[0089] Please refer to Figure 1In this embodiment, the suction mechanism 13 also includes a guide rod 135 and a hanger 137. The guide rod 135 is used to fix the suction mechanism 13, and the hanger 137 is used to drive the suction mechanism 13 to move in different directions. The hanger 137 includes a first shaft 1371, a second shaft 1372, and a third shaft 1373. The first shaft 1371 extends along a first direction X, the second shaft 1372 extends along a second direction Y, and the third shaft 1373 extends along a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The guide rod 135 is slidably fixed to one end of the third shaft 1373, thereby driving the suction mechanism 13 to slide along the third direction Z. The first shaft 1371 is slidably fixed to the second shaft 1372, and the second shaft 1372 is slidably fixed to the other end of the third shaft 1373, thereby driving the suction mechanism 13 to slide along the first direction X and the second direction Y.

[0090] Please also refer to Figure 1 and Figure 7 The positioning mechanism 15 is used to locate the relative positions of the material 7 and the protective shell 5. The positioning mechanism 15 includes a first positioning mechanism 151 and a second positioning mechanism 153. The first positioning mechanism 151 is arranged on the side of the transfer mechanism 11 away from the suction mechanism 13, and the second positioning mechanism 153 is arranged on the side of the suction mechanism 13 away from the transfer mechanism 11. The first positioning mechanism 151 is used to locate the position of the material 7, and the second positioning mechanism 153 is used to locate the position of the protective shell 5.

[0091] After the suction mechanism 13 absorbs the material 7 from the loading mechanism 17, it transfers the material 7 to the side of the first positioning mechanism 151 for positioning. The first positioning mechanism 151 captures an image of the material 7 and the suction mechanism 13, and through image processing, captures the outline of the material 7, thereby locating the position of the material 7 relative to the suction mechanism 13. Specifically, the first positioning mechanism 151 obtains brightness and color information from the image, extracts edge information from the brightness and color information, removes noise from the brightness information, and obtains the edge of the material 7. The first positioning mechanism 151 can be a camera or other positioning mechanism, and this application does not limit it.

[0092] The second positioning mechanism 153 is provided on the suction mechanism 13 and is arranged toward the transfer mechanism 11. After the suction mechanism 13 sucks the material 7, as the suction mechanism 13 moves, the second positioning mechanism 153 takes a photo of the protective shell 5 and captures the outline of the protective shell 5 through image processing, thereby locating the relative position of the protective shell 5 and the suction mechanism 13. Based on the relative position of the protective shell 5 and the suction mechanism 13 provided by the second positioning mechanism 153 and the position of the material 7 relative to the suction mechanism 13 provided by the first positioning mechanism 151, the relative position of the protective shell 5 relative to the material 7 is obtained. This allows the suction mechanism 13 to place the material 7 into the protective shell 5 more accurately, avoiding damage to the material 7, which is conducive to improving processing accuracy and improving production yield.

[0093] Please refer to Figure 1 , the loading mechanism 17 is used to carry and transfer the disassembled electronic device, the suction mechanism 13 sucks out the material 7 from the disassembled electronic device, and transfers the material 7 into the protective shell 5. In this embodiment, the loading mechanism 17 includes a loading slide rail 171 and a tray 173 provided on one side of the loading slide rail 171, and the tray 173 is slidably fixed on the loading slide rail 171. First, the electronic device is manually disassembled, and the disassembled electronic device is placed on the tray 173 so that the side containing the material 7 is close to the suction mechanism 13. The loading slide rail 171 transfers the tray 173 carrying the electronic device to a position close to the suction mechanism 13, and the suction mechanism 13 sucks out the material 7 from the disassembled electronic device. In other embodiments, the loading mechanism 17 may also include only one slidable carrier, which is not limited in this application.

[0094] The transfer device 1 may also include a processor (not shown) and an alarm (not shown). The processor is used to control the coordinated operation of the transfer device 1 and the material removal device 3. After the manipulator 31 grabs the protective shell 5 containing the material 7 from a preset position, a new protective shell 5 can be placed at the preset position, allowing the transfer process to proceed continuously, thereby improving production efficiency, reducing waste of human resources, and thus reducing costs. The alarm is used to sound an alarm when an error step or an event outside the program setting occurs in the loading and unloading equipment 100.

[0095] Please also refer to Figure 1 and Figure 8The manipulator 31 is arranged on one side of the material tray 33 for carrying the protective shell 5. The manipulator 31 is used to transfer the protective shell 5 to the carrying plate 111, and is used to grab the protective shell 5 with the material 7 placed thereon from a preset position. The manipulator 31 includes a first arm 311, a second arm 313, and a driving module 315. The first arm 311 and the second arm 313 are arranged in parallel, and the driving module 315 is used to drive the first arm 311 and the second arm 313 to move relative to each other. When the manipulator 31 needs to grab the protective shell 5 / the protective shell 5 with the material 7 placed thereon, the driving module 315 drives the first arm 311 and the second arm 313 to move in a direction away from each other. When the first arm 311 and the second arm 313 contact the protective shell 5 with the material 7 placed thereon, the driving module 315 drives the first arm 311 and the second arm 313 to move in a direction towards each other, thereby completing the grabbing process of the manipulator 31. Specifically, the second arm 313 includes a curved portion 3131 that protrudes away from the first arm 311, thereby forming an accommodating space 3131a. The degree of protrusion of the curved portion 3131 depends on the size of the flexible printed circuit board 73. The accommodating space 3131a is used to accommodate the flexible printed circuit board 73 of the material 7, preventing damage to the flexible printed circuit board 73 during the gripping process of the second arm 313.

[0096] The specific working process of the loading and unloading equipment 100 for transferring the rear camera module of a returned mobile phone to the protective case 5 is as follows: the loading mechanism 17 transfers the disassembled returned mobile phone to a position close to the suction mechanism 13. The suction mechanism 13 extracts the rear camera module from the disassembled returned mobile phone and transfers it to the positioning mechanism 15, which determines the position of the rear camera module. The robot 31 transfers the protective case 5 of the rear camera module from the material tray 33 to the transfer mechanism 11, which fixes the protective case 5 in a preset position. The positioning mechanism 15 determines the position of the protective case 5 on the transfer mechanism 11, thereby determining the relative position of the rear camera module and the protective case 5. Before placing the rear camera module, the suction mechanism 13 adjusts the position of the rear camera module based on the relative position of the rear camera module and the protective case 5, aligning the rear camera module with the protective case 5. The robot 31 grabs the protective case 5 with the rear camera module from the preset position. In other embodiments, the loading and unloading equipment 100 can also be used to transfer mobile phone chips, and place the side of the mobile phone chip soldered with solder in the protective shell 5 to prevent the solder from being damaged. This application does not limit this.

[0097] The loading and unloading equipment 100 provided in the embodiment of the present application transfers the protective shell 5 to the transfer mechanism 11 by setting a manipulator 31. The fixing module 113 of the transfer mechanism 11 fixes the protective shell 5 at a preset position. The relative positions of the protective shell 5 and the material 7 are positioned by the positioning mechanism 15. The suction mechanism 13 can place the material 7 into the protective shell 5 more accurately to avoid damaging the material 7, which is beneficial to improving processing accuracy and improving production yield; through the coordinated operation of the transfer device 1 and the material picking device 3, the manipulator 31 grabs the protective shell 5 with the material 7 from the preset position, and then can place a new protective shell 5 at the preset position, thereby making the transfer process continuous, which is beneficial to improving production efficiency, reducing waste of human resources, and thus helping to reduce costs.
