The clamping end 51 clamps the cover plate 500 on the suction end 41 and adjusts the posture and then transports it to the sub-hanging 200, or removes the cover plate 500 on the sub-hanging 200 and transports it to the suction end 41. The operating mechanism 6 is provided with an expansion end 61 opened and closed along the first direction, which is used to tighten or loosen the spring pieces 300 on the sub-hanging 200, and the cover plate 500 is automatically stuck on the paired spring pieces 300, and the cover plate 500 is clamped by the paired spring pieces 300, or is separated from the spring pieces 300, so that the cover plate 500 can be automatically hung up and down.

[0023] It is worth noting that, in this embodiment, the first direction and the second direction are two orthogonal directions, and the first direction and the second direction are both located on the same horizontal plane, that is, the first direction and the second direction are both perpendicular to the vertical direction.

[0024] The first conveying mechanism 1 includes a feed component 11, a lifting component 12 and a discharge component 13 arranged in sequence along a first direction. The mother hanger 100 is input to the feed component 11 from the previous process. When the mother hanger 100 reaches the lifting component 12, the mother hanger 100 hangs the sub-hanger 200 or lowers the sub-hanger 200 layer by layer at the lifting component 12, and is output from the discharge component 13 to the next process after completing the hanging or lowering operation.

[0025] In this embodiment, the feeding assembly 11 includes a plurality of first rollers 111 and a first baffle 112. The plurality of first rollers 111 are distributed along the first direction and rotate on the frame 9. The rotation central axes of the plurality of first rollers 111 are located in the same horizontal plane, that is, the tops of the plurality of first rollers 111 are tangent to the same horizontal plane, so that the transported mother hanger 100 can be transported to the lifting assembly 12 in a horizontal posture. Preferably, one of the first rollers 111 is driven by a motor to realize active rotation. In this embodiment, the first baffles 112 are in pairs, and the two first baffles 112 are respectively fixed on the frame 9 at both ends of the length direction of the first rollers 111, that is, the first baffles 112 are arranged along the first direction to form a channel for the mother hanger 100 to pass through, and the two first baffles 112 are parallel to each other to ensure that the mother hanger 100 enters the lifting assembly 12 in a correct posture.

[0026] The lifting assembly 12 includes a lifting guide rail 121 and a supporting platform 122. The lifting guide rail 121 is fixedly connected to the frame 9 in the vertical direction. The supporting platform 122 is slidably connected to the lifting guide rail 121 in the vertical direction. The top of the supporting platform 122 is configured as a plane for supporting the mother hanger 100. The supporting platform 122 is opposite to the output end of the second conveying mechanism 2 in the second direction, so that the sub-hanging 200 can hang the mother hanger 100 up and down.

[0027] The bearing platform 122 is provided with a second roller 123, the rotation center axis of the second roller 123 is parallel to the rotation center axis of the first roller 111, and the second roller 123 is driven by a motor to realize active rotation. When the bearing platform 122 is docked with the discharge assembly 13, the second roller 123 drives the mother hanger 100 to move toward the discharge assembly 13. A pair of second baffles 124 are also provided on the top of the bearing platform 122, and the second baffles 124 and the first baffles 112 are arranged one by one along the first direction, that is, the two second baffles 124 in a pair are fixed on the bearing platform 122 at both ends of the second roller 123, and the two second baffles 124 are arranged in parallel to limit the mother hanger 100 from being in a locked state in the second direction.

[0028] The discharging assembly 13 includes a plurality of third rollers 131 and a third baffle 132. The plurality of third rollers 131 are distributed along the first direction and rotate on the frame 9. The rotational central axes of the plurality of third rollers 131 are located in the same horizontal plane, that is, the tops of the plurality of third rollers 131 are tangent to the same horizontal plane, and the rotational central axes of the third rollers 131 and the rotational central axes of the first rollers 111 are located in the same horizontal plane, so that the transported mother hanger 100 can be transported from the feeding assembly 11 to the discharging assembly 13 in a horizontal posture after passing through the lifting assembly 12. Preferably, one of the third rollers 131 is driven by a motor to realize active rotation. In this embodiment, the third baffles 132 are in pairs, and the two third baffles 132 are respectively fixed on the frame 9 at both ends of the third roller 131 in the length direction, that is, the third baffles 132 are arranged along the first direction to form a channel for the mother hanger 100 to pass through, and the two third baffles 132 are parallel to each other. The paired third baffles 132 are located on the delay line of the corresponding first baffle 112 in the first direction to ensure that the mother hanger 100 enters the discharge assembly 13 from the lifting assembly 12 in the correct posture.

[0029] The first conveying mechanism 1 also includes a plurality of limiting components 14. In the present embodiment, the limiting components 14 are three groups, one of which is fixedly arranged at the output end of the feeding component 11 close to the lifting component 12. The limiting components 14 protrude upward to limit the female hanger 100 located in the feeding component 11 to remain stationary to avoid collision with the female hanger 100 located in the lifting component 12. After the female hanger 100 located in the lifting component 12 leaves, the limiting components 14 contract to allow the female hanger 100 located in the feeding component 11 to move to the supporting platform 122; one of which is fixedly arranged at the output end of the supporting platform 122 close to the discharging component 13 to limit the female hanger 100 located on the supporting platform 122 to remain relatively stationary with the supporting platform 122 to ensure accurate positioning of the sub-hanging 200 and the female hanger 100; one of which is fixedly arranged at the output end of the discharging component 13 away from the lifting component 12, so that the female hanger 100 sent to the discharging component 13 remains stationary for accurate transportation of the equipment of the next process. Taking the limiting component 14 of the feed component 11 as an example, the limiting component 14 includes a limiting guide rail 141 and a limiting block 142. The limiting guide rail 141 is fixed to the feed component 11 in the vertical direction, and the limiting slider is slidably connected to the limiting guide rail 141 in the vertical direction. When the limiting slider slides to the top of the limiting guide rail 141, the limiting slider is higher than the first roller 111 to limit the mother hanger 100.

[0030] like Figure 4As shown, the second conveying mechanism 2 includes a conveying platform 21 and a conveying guide rail 22. The conveying guide rail 22 is fixed on the frame 9 along the second direction. The conveying platform 21 is slidably connected to the conveying guide rail 22. A clamping assembly 23 is fixed on the top of the conveying platform 21 for positioning the sub-hanging 200. Specifically, the clamping assembly 23 is a clamping cylinder, which moves along the first direction to clamp and position the sub-hanging 200. The frame 9 at one end of the conveying guide rail 22 toward the first conveying mechanism 1 is recessed downward to have a space for accommodating the first conveying mechanism 1, that is, the feeding assembly 11 and the discharging assembly 13 are lower than the conveying guide rail 22 in the vertical direction. The lifting guide rail 121 drives the load-bearing platform 122 to have at least two movement states. In state one, the lifting guide rail 121 drives the mother hanger 100 on the load-bearing platform 122 to rise, so that the lowest layer of the mother hanger 100 is docked with the sub-hanger 200 of the conveying guide rail 22. In state two, the lifting guide rail 121 drives the mother hanger 100 on the load-bearing platform 122 to descend, so that the highest layer of the mother hanger 100 is docked with the sub-hanger 200 of the conveying guide rail 22. In addition to the above two states, the lifting guide rail 121 drives the mother hanger 100 on the load-bearing platform 122 to dock with the sub-hanger 200 of the conveying guide rail 22 layer by layer.

[0031] like Figure 5 As shown, the frame 9 is fixed with a pick-and-place mechanism 7, which is located at the top of the conveying guide rail 22, and the pick-and-place mechanism 7 is close to the lifting assembly 12. The pick-and-place mechanism 7 includes a first transmission assembly 71 and a pick-and-place clamp 72. The first transmission assembly 71 drives the pick-and-place clamp 72 to clamp the sub-hanging 200 and send it into the mother hang 100, or to take out the sub-hanging 200 in the mother hang 100. The first transmission assembly 71 includes a first linear slide rail 711, a second linear slide rail 712 and a third linear slide rail 713. The first linear slide rail 711 is fixed on the frame 9 along the second direction, the second linear slide rail 712 is slidably connected to the first linear slide rail 711 along the second direction, the third linear slide rail 713 is slidably connected to the second linear slide rail 712, the third linear slide rail 713 is arranged in the vertical direction, and the pick-and-place clamp 72 is slidably connected to the third linear slide rail 713 in the vertical direction. The pick-and-place clamp 72 is made to move in three orthogonal axes, and the clamping end 51 of the pick-and-place clamp 72 is set in the direction of the lifting assembly 12. Preferably, the pick-and-place clamp 72 opens and closes in the vertical direction to clamp the sub-hanging 200. More preferably, in order to improve the clamping stability of the sub-hanging 200, the third slide rail is provided with two synchronously moving pick-and-place clamps 72.

[0032] like Figure 1 As shown, in this embodiment, in order to improve the efficiency of the sub-hanging 200 and the mother hanging 100, two lifting assemblies 12 are arranged along the first direction between the feeding assembly 11 and the discharging assembly 13, which are used to simultaneously carry two mother hangings 100. Correspondingly, the second conveying mechanism 2 is divided into two groups, and the second conveying mechanism 2 corresponds to the lifting assembly 12 one by one. A pick-up and place mechanism 7 for hanging the sub-hanging 200 up and down is provided above the second conveying mechanism 2.

[0033] like Figure 6 As shown, the feeding mechanism 3, the transfer mechanism 5 and the operating mechanism 6 are all arranged near the end of the conveying guide rail 22 away from the first conveying mechanism 1. The feeding mechanism 3 includes a turntable 31 and a material string rod 32. The turntable 31 is rotatably connected to the frame 9. Specifically, the turntable 31 is rotated by a motor control, and the top of the turntable 31 is configured as a plane for carrying the cover plate 500. A plurality of clearance grooves 33 are provided on the outer peripheral side edge of the turntable 31. The plurality of clearance grooves 33 are arranged in a single row array along the second direction. The openings of the clearance grooves 33 face the outer peripheral side of the turntable 31, and at the same time ensure that the clearance grooves 33 remain through in the vertical direction. Preferably, the clearance grooves 33 are provided in two rows, and the two rows of clearance grooves 33 are symmetrically distributed about the rotation center of the turntable 31. The material string rod 32 is fixedly connected to the top of the turntable 31 between the two clearance grooves 33 in the vertical direction, that is, the material string rod 32 and the clearance grooves 33 are arranged at intervals. The cover plate 500 is strung on the material string rod 32, and the edge of the cover plate 500 overlaps with the clearance groove 33 in the vertical direction. One material string rod 32 can pass through multiple sheet-shaped cover plates 500 in the vertical direction.

[0034] A fork plate 34 is provided between the turntable 31 and the conveying guide rail 22. The fork plate 34 is slidably connected to the frame 9 in the vertical direction. The travel range of the fork plate 34 in the vertical direction is higher than the highest point of the material string rod 32 and lower than the turntable 31, so as to lift the cover plate 500 on the material string rod 32 for the material taking mechanism 4 to take the material, while avoiding conflict with the rotation of the turntable 31. Preferably, the fork plate 34 is slidably connected to the frame 9 through a linear module, and the fork plate 34 is configured as a long strip plate arranged along the second direction. The fork plate 34 protrudes toward the turntable 31 with a plurality of support protrusions 35 matching the clearance grooves 33. When the fork plate 34 rises in the vertical direction, the supporting protrusion 35 passes through the giving way groove 33 in the vertical direction and lifts the cover plate 500. The two supporting protrusions 35 jointly support a string of cover plates 500, evenly sharing the weight of the cover plates 500, avoiding tilting or shaking caused by single-point force, and ensuring that the cover plates 500 remain stable during transportation.

The second linear guide 422 is slidably connected to the first linear guide 421 along the first direction, and the second linear guide 422 is arranged in the vertical direction. The third linear guide 423 is slidably connected to the second linear guide 422 along the vertical direction, and the third linear guide 423 is horizontally arranged along the second direction, that is, the third linear guide 423 extends toward the picking and placing mechanism 7. The adsorption end 41 is fixed at the bottom of the third linear guide rail 423. There are multiple adsorption ends 41 evenly distributed in an array along the second direction. Each adsorption end 41 is arranged downward in the vertical direction to adsorb the cover plate 500 on the material string rod 32 so that the cover plate 500 is transported in a horizontal state. In the first direction, the adsorption end 41 corresponds to a single row of material string rods 32 one by one, that is, one adsorption end 41 can adsorb and transfer one cover plate 500 on one material string rod 32. Each adsorption end 41 can adsorb synchronously. Preferably, the adsorption end 41 is a suction cup, and each suction cup is connected to a negative pressure pump. The driving component 42 drives the adsorption end 41 to move between the feeding mechanism 3 and the transfer mechanism 5 to move the cover plate on the feeding mechanism 3 to the transfer mechanism 5.

[0036] A floating guide rail 43 and a spring 44 are provided between the adsorption end 41 and the third linear guide rail. The floating guide rail 43 is fixed to the third linear guide rail in the vertical direction, and the adsorption end 41 is slidably connected to the floating guide rail 43 in the vertical direction. One end of the spring 44 is fixedly connected to the adsorption end 41, and the other end is fixedly connected to the floating guide rail 43. In other embodiments, the spring 44 can be fixed to the third linear guide rail. The floating guide rail 43 and the spring 44 allow the adsorption end 41 to have a certain floating range in the vertical direction, and can automatically adapt to the height deviation or unevenness of the cover plate 500, avoiding the risk of adsorption failure or damage to the cover plate 500 due to inconsistent height of the cover plate 500, and can absorb the impact force when the adsorption end 41 contacts the cover plate 500, providing a flexible adsorption process.

[0037] A guide rail 91 is provided in the frame 9, and the guide rail 91 spans above the conveying rail 22 along the first direction, is parallel to the second linear rail 712, and is located on the side of the second linear rail 712 away from the first conveying mechanism 1. The transfer mechanism 5 and the operating mechanism 6 are both slidably connected to the guide rail 91 along the first direction, and the transfer mechanism 5 and the operating mechanism 6 extend in a direction away from the second linear rail 712.

[0038] like Figure 8As shown, the transfer mechanism 5 includes a fourth linear guide 52, a transfer block 53 and a clamping carrier 54. The fourth linear guide 52 is slidably connected to the guide rail 91 along the first direction. The fourth linear guide 52 is arranged in the vertical direction. The transfer block 53 is slidably connected to the fourth linear guide 52 in the vertical direction. The clamping carrier 54 is rotatably connected to the transfer block 53 through a motor. The rotation center axis of the clamping carrier 54 is arranged along the first direction. The clamping carrier 54 is configured to be a long strip along the second direction. The clamping carrier 54 is rotatably connected to a plurality of clamping ends 51. The clamping ends 51 are arranged on the same side of the clamping carrier 54. The rotation center axis of each clamping end 51 is parallel, and the rotation center axis of each clamping end 51 is located in the same plane. The plurality of clamping ends 51 correspond to the adsorption ends 41 one by one along the first direction. The plurality of clamping ends 51 can synchronously clamp the cover plate 500 on the adsorption end 41 and adjust the posture of the cover plate 500.

[0039] Specifically, the clamping carrier 54 is provided with a rack and a plurality of gears, and the gears are all meshed with the rack, and each gear is fixedly connected to a corresponding clamping end 51, and the rotation center axis of the gear is coaxial with the rotation center of the corresponding clamping end 51. One of the gears is a driving gear, and the driving gear is driven to rotate by a motor to realize that each clamping end 51 can rotate synchronously. In this embodiment, the clamping end 51 is a mechanical clamp, and in other embodiments, the clamping end 51 is a pneumatic clamp or an adsorption device.

[0040] like Fig. 9 As shown, the operating mechanism 6 includes a fifth linear guide rail 62 and a tensioning carrier 63. The fifth linear guide rail 62 is slidably connected to the guide rail 91, and the fifth linear guide rail 62 and the fourth linear guide rail 52 are located on the same side of the guide rail 91. The fifth linear guide rail 62 is arranged in the vertical direction, and the tensioning carrier 63 is slidably connected to the fifth linear guide rail 62 in the vertical direction. The tensioning carrier 63 is configured as a long strip structure along the second direction, and the bottom surface of the tensioning carrier 63 is a horizontal plane. The tensioning carrier 63 is provided with a plurality of expansion ends 61, and the expansion ends 61 are opened and closed along the first direction to control the tension of the elastic member on the sub-hanging 200. The plurality of expansion ends 61 are distributed in an array along the first direction, and the expansion ends 61 correspond to the clamping ends 51 one by one along the first direction.

[0041] Specifically, the tensioning carrier 63 is provided with a first driving rod 64 and a second driving rod 65, which are arranged in parallel, and the first driving rod 64 and the second driving rod 65 move in opposite or opposite directions along a first direction. In this embodiment, the first driving rod 64 and the second driving rod 65 are controlled by synchronous belt transmission, and in other embodiments, the first driving rod 64 and the second driving rod 65 are controlled by electric screw or worm gear transmission.

[0042] like Fig.10As shown, the expansion end 61 includes a first clamp 611 and a second clamp 612, wherein the first clamp 611 is fixed to the first driving rod 64, and the second clamp 612 is fixed to the second driving rod 65, and the first clamp 611 and the second clamp 612 move in opposite or opposite directions through the first driving rod 64 and the second driving rod 65. The first clamp 611 and the second clamp 612 both protrude in a direction away from the tensioning carrier 63 to clamp the paired spring pieces 300 on the sub-hanger 200.

[0043] The principle of automatic hanging: There are two rows of material string rods 32 on the turntable 31, and the single row material string rod 32 located far away from the fork plate 34 is sleeved with a cover plate 500 through the previous process, so that each material string rod 32 is sleeved with multiple cover plates 500 (with holes in the center), and the fork plate 34 is located at the bottom of the turntable 31. After the cover plates 500 are loaded, the turntable 31 rotates 180°, and the single row material string rod 32 with the cover plates 500 is located above the fork plate 34. The fork plate 34 rises and synchronously pushes the cover plates 500 on each material string rod 32, so that the top cover plate 500 moves to the top of the material string rod 32. The adsorption component moves to the top of the material string rod 32 through the drive component 42, and adsorbs the top cover plate 500 of each material string rod 32, and then moves to a position close to the transfer mechanism 5 through the drive component 42 to wait. The transport mechanism 5 adjusts its posture so that the clamping end 51 clamps the cover plate 500 from the side and allows the cover plate 500 to be separated from the adsorption end 41. The transport mechanism 5 adjusts the posture of the cover plate 500 by rotation and translation so that the cover plate 500 is in a vertical state. At the same time, the operating mechanism 6 moves close to the paired spring sheets 300, that is, the first clamp 611 and the second clamp 612 are located to pair with the spring sheets 300. The first clamp 611 and the second clamp 612 clamp the spring sheets 300 so that the two paired spring sheets 300 are elastically deformed in opposite directions, and the rods 400 on the spring sheets 300 for supporting the cover plate 500 are close to facilitate insertion into the hole of the cover plate 500. Then the operating mechanism 6 is separated from the paired spring sheets 300, so that the spring sheets 300 rebound, and the rods 400 on the spring sheets 300 are pressed against the inner wall of the hole of the cover plate 500. The operating mechanism 6 hangs the cover plates 500 on the spring pieces 300 on the sub-hanging 200 row by row.

[0044] After the sub-hanging 200 completes the mounting of the cover plate 500, the sub-hanging 200 moves along the conveying rail 22 toward the lifting assembly 12. At this time, the carrier 122 is loaded with the mother hanger 100, and the opening of the mother hanger 100 is arranged toward the output end of the conveying rail 22. When the sub-hanging 200 is moved to the end of the conveying rail 22 close to the mother hanger 100, the first transmission assembly 71 drives the pick-and-place clamp 72 to clamp the sub-hanging 200 and push the sub-hanging 200 into the mother hanger 100 along the second direction. The inside of the mother hanger 100 is evenly layered along the vertical direction. The mother hanger 100 moves from top to bottom, cooperates with the pick-and-place mechanism 7 and the conveying rail 22, and loads the sub-hanging 200 layer by layer into the inside of the mother hanger 100. After the loading is completed, the mother hanger 100 is transported toward the lower chat assembly direction. Embodiment 2:

During the unloading process, the transfer mechanism 5 removes the cover plate 500 from the elastic member and places it flat on the top of the positioning platform 812. The positioning plate is moved toward the positioning platform 812 by the motor and abuts against the outer peripheral side of the positioning platform 812 to push the cover plate 500 for preliminary positioning.

[0046] The frame 9 is fixed with an adsorption assembly, which includes a transmission member 851 with three-axis transmission and a plurality of adsorption heads 852. The transmission member 851 is fixed on the frame 9, and the adsorption head 852 is fixed at the output end of the transmission member 851. The adsorption head 852 is driven by the transmission member 851 to descend and transfer the cover plate 500 located on the first positioning assembly 81 to the second positioning assembly 82. The second positioning component 82 includes a support frame 821 and a support platform 822, and the support platform 822 is rotatably connected to the support frame 821 through a gear rack. The rotation center axis of the support platform 822 is arranged in the vertical direction, and the top of the support platform 822 is constructed as a horizontal plane for carrying the cover plate 500. The adsorption head 852 transfers the cover plate 500 located on the positioning platform 812 to the support platform 822. The frame 9 is provided with a visual inspection module 84, and the visual inspection module 84 is located on the top of the support platform 822. The visual inspection module 84 faces the support platform 822 to detect the position deviation and angle deviation of the cover plate 500 on the support platform 822. The correction component 83 includes a transmission frame 831 and a positioning clamp 832. The transmission frame 831 is slidably connected to the frame 9 along the first direction, the second direction and the vertical direction. The positioning clamp 832 is rotatably connected to the transmission frame 831. The rotation center axis of the positioning clamp 832 is set along the first direction. The positioning clamp 832 clamps the cover plate 500 located on the supporting platform 822 to adjust the position. The supporting platform 822 rotates to adjust the angular position of the cover plate 500.

[0047] The rack 9 is provided with a feeder 86 near the second positioning assembly 82, and the feeder 86 includes a mechanical arm (not shown) for transferring the cover plate 500, and a tray for carrying the cover plate 500 is placed on the feeder 86. The steps of the automatic lowering process before the transfer mechanism 5 are opposite to the automatic upper hanging process, and the process after the transfer mechanism 5 is as described in Example 2.
