[0025] The beneficial effects of this technical solution are:

[0026] ① In this technical solution, by setting up a clamping device, a transportation device, a loading device and an assembly device, it is possible to realize automatic transportation, automatic loading, automatic locking and automatic clamping of the positioning identification card, with a high degree of intelligence.

[0027] ② In this technical solution, an RFID reader is provided to identify the product information of the positioning identification card, and the control device determines whether it is necessary to clamp the front cover in the feeding device according to the product information. Therefore, this solution has strong versatility.

[0028] ③ In this technical solution, by setting up an NG conveyor belt and setting a second detection sensor and a third detection sensor on the NG conveyor belt, NG products can be moved in an orderly manner, and workers can be reminded to collect them after they are full.

[0029] ④ In this technical solution, the front cover is positioned by setting a Y-axis positioning component and an X-axis positioning component, and the rear cover is pressed down by a pressing component, so that the front cover and the rear cover can be pressed tightly to ensure the normal locking of the subsequent locking screw machine.

[0030] ⑤ In this technical solution, by setting the fourth detection sensor, it is possible to detect whether there are parts in the screw machine fixture, and the subsequent program can be started only after the parts are found. By setting the fifth detection sensor, it is possible to determine whether the rear cover is pressed tightly on the front cover to ensure the normal locking of the subsequent screw machine.

[0031] ⑥ In this technical solution, by setting up the first visual component, the shape and position of the parts in the shuttle fixture and the feeding device can be identified to ensure the accuracy of the gripping robot. By setting up the second visual component, the shape and position of the parts gripped by the gripping robot can be accurately judged to ensure the accuracy of assembly.

[0032] ⑦ This technical solution sets up a loading mechanism, so workers only need to pull the first rack out of the rack, and then stack the trays filled with materials in the first rack in sequence. There is no need to lift the basket filled with trays to the grabbing position, thereby reducing the labor intensity of workers. By setting up a unloading mechanism, empty trays can be transferred to the second rack for storage. Workers can directly move the trays in the second rack and then load the materials into it, which improves efficiency and reduces the labor intensity of workers.

[0033] ⑧ The technical solution sets a lower pressure plate to prevent the empty material tray from failing to fall into place. And by setting a limit block, a limit seat and a sensor, and rotating the lower pressure plate to the rotating seat, it can prevent the lower pressure block from damaging the material tray when the lower pressure piece overshoots. The control device can close the lower pressure piece according to the sensing signal of the sensor.

[0034] ⑨ This technical solution can detect whether the material tray is pulled back into place by setting a first in-place sensor, thereby preventing the material tray from being stuck due to the jacking up due to failure to pull back into place.

[0035] ⑩ By setting the first limit sensor and the second limit sensor in the limit component, it is possible to avoid the situation where the material tray collides with the limit plate in place when the second driving member overshoots, causing damage to the material tray.

[0094] The specific implementation process is as follows:

[0095] The worker puts the front cover 9 of the first positioning identification card or the assembled second positioning identification card into the shuttle jig 13, and the front cover 9 of the first positioning identification card is installed with an identification component. The transport module 14 transports the shuttle jig 13. The gripping robot 16 grabs the front cover 9 of the first positioning identification card (K3) or the second positioning identification card (K5 or K9) from the shuttle jig 13. The second positioning identification card (K5 or K9) has been manually covered with the back cover 10 on the front cover 9 in the previous process. Before the gripper 20 grabs, the first visual component 17 will identify the shape and position of the front cover 9 of the first positioning identification card or the second positioning identification card in the shuttle jig 13 and send it to the control device. The control device processes and adjusts the state of the gripping robot 16 so that the gripper 20 can accurately grab the front cover 9 of the first positioning identification card or the second positioning identification card. The gripping robot 16 grabs the front cover 9 of the first positioning identification card or the second positioning identification card to the RFID reader 12, and the RFID reader 12 reads the information of the read-write identification card 11 on the front cover 9 and sends it to the control device, and the control device identifies the product information (K3, K5, K9) according to the information. After that, the gripping robot 16 places the grabbed front cover 9 of the first positioning identification card or the second positioning identification card in the screw machine fixture 24. At this time, the front cover 9 of the first positioning identification card or the second positioning identification card blocks the sensing light of the fourth detection sensor 34, and the fourth detection sensor 34 sends the sensing signal to the control device. The control device starts the Y-axis positioning component 25 and the X-axis positioning component 26 for positioning. If the control device detects that the product information is the first positioning identification card, the control device starts the gripping robot 16 to the feeding device 5, and the first visual component 17 identifies the shape and position of the material tray 48 on the feeding device 5. The control device adjusts the position of the gripping robot 16 and then grabs the back cover 10 of the first positioning identification card in the material tray 48. The gripping robot 16 moves the gripped back cover 10 to the second visual component 137 for identification and positioning. After that, the gripping robot 16 places the back cover 10 of the first positioning identification card on the front cover 9 of the first positioning identification card. If the control device detects that the product information is the second positioning identification card, the gripping robot 16 does not need to grip the back cover 10. After the gripping robot 16 moves vertically to the set position, the telescopic structure 38 drives the back cover jig 32 and the pressing assembly to move toward the direction of the front cover jig 31 until it reaches the set position. Then the pressing assembly drives the back cover jig 32 to press down, pressing the back cover 10 against the front cover 9. After pressing, the fifth detection sensor 36 detects the distance between it and the back cover 10, and sends the distance information to the control device, which determines whether the back cover 10 is assembled properly. If the assembly is unqualified, the pressing structure 39 and the telescopic structure 38 are driven to open the screw machine fixture 24, and the Y-axis positioning component 25 is driven to return, and then the clamping robot 16 clamps the unqualified identification card to the NG conveyor belt 41.If the assembly is qualified, the control device starts the locking screw machine 21 to lock according to the set program. The locking screw machine 21 will send a signal to the control device whether the locking is successful. The control device drives the pressing structure 39 and the telescopic structure 38 to open the screw machine fixture 24, and drives the Y-axis positioning component 25 to return, and then the clamping robot 16 clamps the identification card. If the locking is successful, the clamping robot 16 clamps the assembled identification card to the shuttle fixture 13, and the transportation module 14 transports it to the next station. If the locking is unsuccessful, the clamping robot 16 clamps the identification card that failed to be locked to the NG conveyor belt 41. Whether the locking is successful is determined by the system of the locking screw machine. If the locking is unsuccessful, the locking screw machine will send a signal to the control device.

[0096] When the gripping robot 16 grips the unqualified identification card to the transmission start end of the NG conveyor belt 41, the second detection sensor 42 will detect the NG product at this position and send the detection information to the control device, which starts the NG conveyor belt 41 and moves the NG conveyor belt 41 by the length of an identification card. At this time, the second detection sensor 42 cannot detect the NG product, and the control device closes the NG conveyor belt 41. When the third detection sensor 43 detects the NG product, it sends the detection information to the control device, which issues a full material alarm to remind workers to take away the NG product.

[0097] The operating principle of the feeding device 5 is as follows:

[0098] The first step is to load the first material rack 51, and the specific steps are as follows: open the door body 58, start the first driving member 50, and the first driving member 50 drives the connecting bottom plate 56 and the limit block 57 to move toward the door body 58 through the fixed plate 54 until the second in-place sensor 116 senses the connecting bottom plate 56, and the second in-place sensor 116 sends the sensing signal to the control device, and the control device closes the first driving member 50. Then the staff presses down the first positioning member 59 to separate the connecting bottom plate 56 and the fixed plate 54, and then pulls the connecting bottom plate 56 through the handle 55, and the connecting bottom plate 56 slides on the second industrial guide rail 53 until the first material rack 51 passes through the door body 58 and is completely located outside the door body 58, and then the staff sequentially adds the material tray 48 equipped with the rear cover 10 into the first material rack 51, and the limit block 57 limits the four corners of the material tray 48. After filling, the staff pushes the connecting bottom plate 56 through the handle 55 to restore it to its original position, and then uses the first positioning member 59 to position the connecting bottom plate 56 and the fixing plate 54. Finally, the first driving member 50 is started, and the first driving member 50 drives the first material rack 51 and the material tray 48 to move toward the loading station position through the fixing plate 54. When the second positioning member 60 senses that the first material rack 51 has reached the loading station position, a signal is sent to the control device, and the control device closes the first driving member 50 and starts the lifting mechanism 46.

[0099] In the second step, the material tray 48 is lifted to the material grabbing position, and the clamping device 3 takes the material from the rear cover 10 in the upper material tray 48. The specific steps are as follows: the control device starts the second driving member 61, and the second driving member 61 drives the vertical block 70 and the receiving frame 63 to move upward through the first synchronous wheel, the second synchronous wheel 66, the threaded rod 67 and the nut seat 68. During the upward movement of the receiving frame 63, the material tray 48 in the first material frame 51 will be lifted upward through the through slot 64 on the connecting bottom plate 56. During the lifting process, the upper body 135 of the material tray 48 will first pass between the two groups of in-place limit plates 73, and the second limit sensor 75 will sense the material tray 48 and send the sensing signal to the control device. The control device then reduces the rotation speed of the second driving member 61, so that the rising speed of the material tray 48 slows down. At the same time, the first limit sensor 74 will sense the distance between it and the lower body 136, and send the sensing signal to the control device. When the set distance is reached, the control device will close the second driving member 61. Then the control device starts the clamping device 3 to grab the rear cover 10 in the uppermost material tray 48 . After the grabbing is completed, the control device starts the unloading mechanism 47 .

[0100] In the third step, the unloading mechanism 47 unloads the empty material tray 48 and stores it in the second material rack 100. The specific steps are as follows: the control device starts the third driving member 83, and the third driving member 83 drives the receiving plate 82 to extend into the tray slots 81 on both sides of the material tray 48 to receive the material tray 48. Then the control device starts the second driving member 61, and the second driving member 61 drives the vertical block 70, the receiving rack 63 and other material trays 48 to move downward through the first synchronous wheel, the second synchronous wheel 66, the threaded rod 67 and the nut seat 68, until the material tray 48 with materials on the top layer no longer blocks the infrared rays emitted by the second positioning component, so that the infrared receiver can smoothly receive the infrared rays, and the second positioning component sends the sensing signal to the control device, and the control device closes the second driving member 61. At this time, a channel is left between the empty material tray 48 and the material tray 48 with materials on the top layer. The control device starts the sixth driving member 103 and the fourth driving member 84. The fourth driving member 84 drives the support plate 85 through the channel. The initial height of the pull-back block 86 is higher than the support plate 85 and higher than the bottom of the empty tray 48. Therefore, when the support plate 85 drives the pull-back block 86 to move, the empty tray 48 will apply pressure to one side of the pull-back block 86, and the pull-back block 86 rotates to compress the elastic member 87. When the pull-back block 86 moves to the outside of the empty tray 48, the empty tray 48 no longer applies force to the pull-back block 86. Therefore, the pull-back block 86 returns to its original position upward under the elastic force of the elastic member 87. At this time, the surface of the pull-back block 86 is higher than the bottom of the tray 48 on the receiving plate 82. Then the control device starts the third driving member 83, and the third driving member 83 drives the receiving plate 82 to return to its original position and no longer receives the tray 48. The empty tray 48 will fall on the support plate 85 under the action of its own gravity. In order to ensure that the support plate 85 falls into place, a lower pressing plate 94 is provided to assist in pressing down, and the control device starts the lower pressing member 93, and the lower pressing member 93 drives the lower pressing plate 94 to move downward, and the lower pressing plate 94 presses down the empty material tray 48 until the empty material tray 48 is located on the support plate 85. In this process, if the lower pressing member 93 is overshot, the lower pressing plate 94 will rotate, so that the distance between the limit plate 99 and the sensing member changes. After the sensing member senses the distance change, it sends a signal to the control device, and the control device immediately closes the lower pressing member 93. After that, the control device starts the fourth driving member 84 and the sixth driving member 103, and the fourth driving member 84 and the sixth driving member 103 drive the support plate 85 and the pull-back block 86 to move back, and the pull-back block 86 drives the material tray 48 above it to move with the support plate 85, and the support plate 85 will move into the opening 106 until the first in-position sensor 117 senses the position of the material tray 48 above through the notch 115 on the lifting plate 104, and the first in-position sensor 117 sends a sensing signal to the control device, and the control device turns off the fourth driving member 84 and the sixth driving member 103. Then the fifth driving member 102 is started to drive the lifting plate 104 to move upward, and the initial height of the lifting plate 104 does not exceed the height of the support plate 85.During the upward movement of the lifting support plate 104, the empty material tray 48 on the support plate 85 will be lifted up. During the upward movement of the empty material tray 48, both sides of the empty material tray 48 will exert an upward force on the inclined surface 113 of the receiving block 108, so that the receiving block 108 rotates, and the back of the receiving block 108 exerts pressure on the spring pin 110 to compress it. After the receiving block 108 rotates, the empty material tray 48 can pass smoothly. At this time, the empty material tray 48 will no longer generate an upward force on the receiving block 108. The receiving block 108 returns to its original position under the elastic force of the spring pin 110, and the top of the receiving block 108 supports the empty material tray 48. The four corners of the empty material tray 48 are limited by the second material rack 100. Then the control device controls the fifth driving member 102 to move in the reverse direction, and the fifth driving member 102 drives the lifting plate 104 to move downward to its original position. At this time, the through-beam switch can successfully receive the light, indicating that the empty material tray 48 has been successfully transferred to the second material rack 100.

[0101] In the above process, after the lifting support plate 104 lifts up the empty material tray 48, the fourth driving member 84 and the sixth driving member 103 drive the support plate 85 to return to the original position. After the empty material tray 48 is transferred by the support plate 85, the second driving member 61 is started, and the second driving member 61 drives the vertical block 70 and the receiving frame 63 to move upward through the first synchronous wheel, the second synchronous wheel 66, the threaded rod 67 and the nut seat 68 until the uppermost material tray 48 contacts the in-place limit plate 73, and then the next batch of materials is grabbed.

[0102] When the full material sensing switch 105 on the second material rack 100 senses the empty material tray 48 on the top layer, a signal is sent to the control device, and the control device issues an alarm to remind the worker to take away the empty material tray 48.
