After the glass plate 23 is coated by the coating machine 25, the glass plate fixture 22 loaded with the coated glass plate 23 is transferred from the coating machine 25 to the positioning unlocking machine 9 of the plate removal conveyor line 14 by the fixture unloading robot 13. The positioning unlocking machine 9 positions the glass plate fixture 22 loaded with the coated glass plate 23 and unlocks the upper plate 222. The clamp unloading robot 13 transfers the upper plate 222 to the right end of the upper plate conveyor line 12, and the upper plate conveyor line 12 transfers the upper plate 222 to the left end of the upper plate conveyor line 12. The plate removal conveyor line 14 conveys the lower plate 221 loaded with the coated glass plate 23 to the loading and unloading machine 7. The loading and unloading machine 7 positions and lifts the lower plate 221, and the empty lower plate 221 is transferred to the loading station of the loading and unloading machine 7, waiting for the glass plate 23 to be clamped before coating. The pallet conveyor line 5 transfers the empty pallet to the right end of the pallet conveyor line 5, and the unloading and transferring robot 15 transfers the coated glass plate 23 to the empty pallet. The pallet filled with coated glass plates 23 is transferred to the second longitudinal conveyor line 16, and the coated glass plates 23 on the pallet are inspected for appearance by the second plate inspection machine 17. According to the detection result of the second plate inspection machine 17, the pallet filled with coated glass plates 23 is transferred to the unloading elevator 18 or the second plate NG line 20. The unloading elevator 18 lowers the pallet with the glass plates 23 with qualified coating and inputs it to the pallet feeding line, and the pallet with the glass plates 23 with unqualified coating flows out from the second plate NG line 20.When the glass plate fixture 22 needs to be cleaned, the fixture loading robot 11 transfers the glass plate fixture 22 in the coating machine 25 to the plate-joining conveyor line 8, and the fixture unloading robot 13 transfers the glass plate fixture 22 in the coating machine 25 to the plate-removing conveyor line 14. The plate-joining conveyor line 8 and the plate-removing conveyor line 14 convey the glass plate fixture 22 to the two stacking and splitting machines 10, and the two stacking and splitting machines 10 stack the glass plate fixture 22 to facilitate the transfer of the glass plate fixture 22. The cleaned glass plate fixture 22 is put in from the left end of the plate-joining conveyor line 8 and the right end of the plate-removing conveyor line 14, and the two stacking and splitting machines 10 split the cleaned glass plate fixture 22 into single glass plate fixtures 22, and the single glass plate fixture 22 is conveyed to the positioning and unlocking machine 9 for positioning, and the fixture loading robot 11 and the fixture unloading robot 13 transfer the positioned single glass plate fixture 22 to the coating machine to wait for use.

[0072] like Figure 3-6 As shown, the glass plate clamp 22 includes an upper plate 222, a lower plate 221, eight self-locking structures 223, eight clamping limit blocks 224, four support shafts 225 and ninety-six elastic pads 226. The upper plate 222 is provided with fifteen second coating holes 2221, and the lower plate 221 is provided with fifteen first coating holes 2212. The first coating holes 2212 and the second coating holes 2221 are both arranged in a matrix, with three columns and five rows, and the first coating holes 2212 correspond to the second coating holes 2221 one by one. Four elastic pads 226 are installed between two adjacent first coating holes 2212, and the four elastic pads 226 are arranged in a square shape. A total of forty-eight elastic pads 226 are installed on the lower plate 221. Four elastic pads 226 are also provided between two adjacent second coating holes 2221, and the four elastic pads 226 are arranged in a square shape. A total of forty-eight elastic pads 226 are arranged on the upper plate 222. The upper plate 222 is connected to the four sides of the lower plate 221 through eight self-locking structures 223. Four support shafts 225 are provided on the lower plate 221 of the glass plate clamp 22. When two glass plate clamps 22 are stacked, the support shafts 225 of the lower glass plate clamp 22 support the upper glass plate clamp 22, so that a certain gap is formed between the two adjacent glass plate clamps 22, which facilitates the insertion of the plug-in structure 102 into the gap. Four clamping limit blocks 224 are installed on both sides of the upper plate 222, and the other four clamping limit blocks 224 are installed on both sides of the lower plate 221.

[0073] like Figure 5As shown, each self-locking structure 223 includes a protective cover plate 2231, a lock catch 2232, a spring fixing shaft 776, a spring cover plate 2233, a lock hook 2234, a spring fixing seat 2235, a reset spring 2236 and a fixing frame 2237. The protective cover plate 2231 is installed on the edge of the upper plate 222, and two protective cover plates 2231 are distributed on each side of the upper plate 222. The lock catch 2232 is installed at the bottom of the protective cover plate 2231. The spring fixing shaft 776 is installed on the spring fixing seat 2235, the lock hook 2234 is rotatably installed on the spring fixing shaft 776, and the reset spring 2236 is sleeved on the spring fixing shaft 776. One end of the reset spring 2236 is embedded in the limiting groove of the spring fixing seat 2235, and the spring cover plate 2233 covers the top of the limiting groove, that is, the spring cover plate 2233 is connected to the spring fixing seat 2235 by bolts, and limits one end of the reset spring 2236. The other end of the return spring 2236 abuts against the lock hook 2234. The spring fixing seat 2235 is installed on the lower plate 221 through the fixing frame 2237, and one end of the lock hook 2234 is located in the unlocking hole 2211 of the lower plate 221. The other end of the lock hook 2234 can be embedded in the lock buckle 2232.

[0074] The protective cover plate 2231 is used to protect and fix the lock buckle 2232. The lock buckle 2232 cooperates with the lock hook 2234 to achieve locking and unlocking between the upper plate 222 and the lower plate 221. The spring fixing shaft 776 is used to install the reset spring 2236 and the lock hook 2234. The spring cover plate 2233 is used to limit one end of the reset spring 2236 to prevent one end of the reset spring 2236 from escaping from the spring fixing seat 2235. The spring fixing seat 2235 is used to limit one end of the reset spring 2236. The reset spring 2236 recovers through its own elasticity to achieve automatic reset of the lock hook 2234. The fixing frame 2237 is used to install the spring fixing seat 2235 on the lower plate 221.

[0075] Description of the use process of the glass plate clamp 22: When the upper plate 222 and the lower plate 221 need to be locked, after the lower plate 221 is positioned by the positioning unlocking machine 9, the clamp loading robot 11 clamps the upper plate 222 from the upper plate conveyor line 12 and places the upper plate 222 vertically on the lower plate 221. Under the push of the clamp loading robot 11, the lock buckle 2232 pushes the lock hook 2234, and the lock hook 2234 rotates downward with the spring fixing shaft 776 as the center, and the reset spring 2236 accumulates force at the same time. When the lock hook 2234 rotates to a certain angle, the lock hook 2234 rotates downward because the horizontal length of the lock hook 2234 is too short, and the lock buckle 2232 cannot continue to push the lock hook 2234. Under the elastic force of the return spring 2236, the lock hook 2234 rotates upward and embeds into the lock buckle 2232, and the lock buckle 2232 hooks the lock buckle 2232, thereby realizing the connection between the upper plate 222 and the lower plate 221. When it is necessary to release the lock of the upper plate 222 and the lower plate 221, the glass plate clamp 22 is transported to the positioning and unlocking machine 9. The rotating cylinder 907 of the positioning and unlocking machine 9 positions the glass plate clamp 22, and the pushing wheel 908 of the positioning and unlocking machine 9 is lifted, and the pushing wheel 908 is inserted into the unlocking hole 2211 and presses the lock hook 2234. The locking hook 2234 is forced to rotate upward with the spring fixed shaft 776 as the center, and the horizontal length of the locking hook 2234 becomes smaller. When the lock buckle 2232 is separated from the limit of the locking hook 2234, the fixture unloading robot 13 grabs the upper plate 222 to separate from the lower plate 221, and transports the upper plate 222 to the upper plate conveyor line 12, thereby realizing the unlocking of the upper plate 222 and the lower plate 221.

[0076] like Figure 7-9As shown, the structure of the fixture loading robot 11 and the fixture unloading robot 13 is the same, which includes a manipulator 131 and a clamping structure 132, and the clamping structure 132 includes a clamping base plate 132a, two synchronous shafts 132b, two first driven synchronous wheels 132c, a first synchronous belt 132d, two clamps 132e, two belt clamps 142h, two clamping cylinders 132i, two push plates 132j, two push cylinders 132k, a second connecting member 132l, four second sliders 132f, four second slide rails 132g and two rotating shaft fixing seats 132m. The clamping base plate 132a is installed on the manipulator 131 through the second connecting member 132l. The two synchronous shafts 132b are fixedly installed at the left and right ends of the clamping base plate 132a through two rotating shafts. The two first driven synchronous wheels 132c are rotatably installed on the two synchronous shafts 132b. The two clamps are connected to the four second sliders 132f, respectively, and the four second sliders 132f are slidably connected to the four second slide rails 132g, respectively. The four second slide rails 132g are installed at the left and right ends of the clamping base plate 132a by bolts. The two ends of the first synchronous belt 132d pass through the two clamps 132e and are connected to the two first driven synchronous wheels 132c, respectively. The two clamps 132e are connected to the left and right ends of the first synchronous belt 132d through two belt clamps 142h, respectively. The two clamping cylinders 132i are installed on the outside of the two clamps 132e and installed on the clamping base plate 132a. The two clamping cylinders 132i are connected to the two clamps 132e, respectively. The two pushing cylinders 132k are installed at the upper and lower ends of the clamping base plate 132a, and the telescopic rods of the two pushing cylinders 132k are connected to the two push plates 132j.

[0077] The manipulator 131 can be purchased in the existing market and is used to carry the glass plate clamp 22; the clamping structure 132 is used to clamp the glass plate clamp 22; the clamping base plate 132a acts as a bracket for installing various components. The synchronization shaft 132b is used to install the first driven synchronization wheel 132c. The cooperation between the first driven synchronization wheel 132c and the first synchronization belt 132d realizes the synchronization of the two clamps 132e, and also ensures that the clamp 132e does not release the glass plate clamp 22 when one of the clamping cylinders 132i fails. The clamp 132e is used to clamp the glass plate clamp 22. The belt clamp 142h is used to connect the first synchronization belt 132d and the clamp 132e. The clamping cylinder 132i provides power for the movement of the clamp 132e. The push plate 132j ​​is used to push the upper plate 222 onto the lower plate 221 to achieve the locking of the upper plate 222 and the lower plate 221. The push cylinder 132k provides power for the movement of the push plate 132j. The second connecting member 132l is used for connecting the clamping base plate 132a with the manipulator 131. The rotating shaft fixing seat 132m is used for installing the synchronous shaft 132b on the clamping base plate 132a.

[0078] Description of the process of the clamping structure 132 clamping the upper plate 222 or the lower plate 221: Two clamping limit blocks 224 are provided on both sides of the upper plate 222 and the lower plate 221. The manipulator 131 moves the clamping structure 132 to the top of the upper plate 222 or the lower plate 221, and the clamping cylinder 132i drives the two clamping claws 132e to approach each other, that is, the two clamping claws 132e approach both sides of the upper plate 222 or the lower plate 221. The two clamping claws 132e simultaneously drive the first synchronous belt 132d to rotate, and the first synchronous belt 132d drives the first driven synchronous wheel 132c to rotate. Under the action of the first synchronous belt 132d and the first driven synchronous wheel 132c, the synchronization of the two clamping claws 132e is achieved. When the two clamping claws 132e completely clamp the clamping limit blocks 224 on both sides of the upper plate 222 or the lower plate 221, the clamping of the upper plate 222 or the lower plate 221 is completed. When one of the clamping cylinders 132i fails, under the thrust of the other clamping cylinder 132i, in addition to pushing the directly connected clamping claw 132e, the other clamping cylinder 132i also indirectly pulls the other clamping claw 132e to press the upper plate 222 or the lower plate 221 through the first synchronous belt 132d and the first driven synchronous wheel 132c.

[0079] The process of the clamping structure 132 pushing the upper plate 222 and locking the lower plate 221 is described as follows: the clamping structure 132 clamps the upper plate 222 and moves it to the lower plate 221. The two pushing cylinders 132k of the clamping structure 132 push the push plate 132j, the push plate 132j ​​pushes the upper plate 222, the upper plate 222 pushes the lock buckle 2232, and the lock buckle 2232 pushes the lock hook 2234 to rotate. When the lock hook 2234 rotates to a certain angle, it falls into the lock buckle 2232, completing the locking of the upper plate 222 and the lower plate 221.

[0080] like Fig.10 and 11As shown, the positioning unlocking machine 9 includes a second cylinder fixing plate 901, a second lifting cylinder 902, two second guide rod bottom plates 909, four second guide rods 904, two second connecting rods 905, a cylinder lifting plate 903, two driven lifting plates 906, four rotating cylinders 907 and eight pushing wheels 908. The second cylinder fixing plate 901 is installed below the plate assembly conveyor line 8 or the plate disassembly conveyor line 14. The second lifting cylinder 902 is installed on the second cylinder fixing plate 901, and the telescopic rod of the second lifting cylinder 902 is connected to the cylinder lifting plate 903. The middle parts of the two second connecting rods 905 are connected to the two ends of the cylinder lifting plate 903, and the two ends of the two second connecting rods 905 are respectively connected to the two driven lifting plates 906. The second guide rod bottom plates 909 are respectively mounted on both sides of the second cylinder fixed plate 901, and the second guide rod bottom plates 909 are also mounted below the plate-closing conveyor line 8 or the plate-removing conveyor line 14. The two driven lifting plates 906 are respectively fixedly connected to the upper ends of the four second guide rods 904, that is, each driven lifting plate 906 is fixedly connected to the upper ends of the two second guide rods 904. The lower ends of the four second guide rods 904 are respectively slidably mounted on the two second guide rod bottom plates 909, that is, each second guide rod bottom plate 909 is slidably connected to the lower ends of the two second guide rods 904. The four rotating cylinders 907 are respectively mounted on the two ends of the two second guide rod bottom plates 909, that is, a rotating cylinder 907 is respectively mounted on the two ends of each second guide rod bottom plate 909, and the four rotating cylinders 907 are located on both sides of the plate-removing conveyor line 14 or the plate-closing conveyor line 8. Eight pushing wheels 908 are distributed on the top of the two driven lifting plates 906, and two pushing wheels 908 are distributed at both ends of each driven lifting plate 906. The eight pushing wheels 908 correspond to the locking hooks 2234 of the eight self-locking structures 223 of the glass plate clamp 22.

[0081] The second cylinder fixing plate 901 is used to fix the second lifting cylinder 902. The second lifting cylinder 902 is used to drive the cylinder lifting plate 903 to rise and fall. The second guide rod bottom plate 909 is used to fix the second guide rod 904 and the four rotating cylinders 907. The second guide rod 904 guides the driven lifting plate 906. The second connecting rod 905 plays a transmission role and is used to drive the driven lifting plate 906 to rise and fall. The cylinder lifting plate 903 is used to drive the second connecting rod 905 to rise and fall. The driven lifting plate 906 is used to install eight pushing wheels 908. The rotating cylinder 907 is used to clamp the four sides of the glass plate clamp 22 to achieve the positioning of the glass plate clamp 22. The pushing wheel 908 is used to be embedded in the unlocking hole 2211 of the glass plate clamp 22 and push the lock hook 2234 to rotate, so as to achieve the unlocking of the upper plate 222 and the lower plate 221.

[0082] The working process of the positioning and unlocking machine 9 is described as follows: When the plate-joining conveyor line 8 conveys the glass plate fixture 22 to the top of the positioning and unlocking machine 9, the four rotating cylinders 907 rotate the blocking rods, and the blocking rods enter the plate-unloading conveyor line 14 to support the two ends of the glass plate fixture 22, thereby realizing the positioning of the glass plate fixture 22. Then the telescopic rod of the second lifting cylinder 902 extends to drive the cylinder lifting plate 903 to rise, and the cylinder lifting plate 903 drives the two driven lifting plates 906 to rise through the second connecting rod 905. The eight pushing wheels 908 on the two driven lifting plates 906 pass through the plate-unloading conveyor line 14 and are inserted into the eight unlocking holes 2211 of the glass plate fixture 22 and push the lock hook 2234 to rotate upward. When the lock buckle 2232 is free from the restriction of the lock hook 2234, the upper plate 222 is disconnected from the lower plate 221, that is, the upper plate 222 can be removed from the lower plate 221. When unlocking is completed, the second lifting cylinder 902 descends, and drives the driven lifting plate 906 to descend through the cylinder lifting plate 903, that is, the eight pushing wheels 908 move out of the unlocking hole 2211 and retract to the bottom of the plate dismantling conveyor line 14. The four rotating cylinders 907 rotate the blocking rod, and the blocking rod moves out of the plate dismantling conveyor line 14. The lower plate 221 continues to move forward driven by the plate dismantling conveyor line 14. The positioning unlocking machine 9 is on the plate dismantling conveyor line 8. During normal production, it only limits the lower plate 221 of the glass plate clamp 22, and then presses down the upper plate 222 through the clamp loading robot 11 to achieve the locking of the upper plate 222 and the lower plate 221. If it is necessary to clean the glass plate clamp 22, in order to improve the removal efficiency of the glass plate clamp 22, the plate combining conveyor line 8 and the plate removing conveyor line 14 are both used to combine the upper plate 222 and the lower plate 221, and the plate combining conveyor line 8 and the plate removing conveyor line 14 are both used to stack and remove the glass plate clamp 22.

[0106] The trolley longitudinal moving device 24 is used to move the fixture trolley 28 longitudinally. The coating machine 25 can be purchased in the existing market and is used to coat the glass plate 23. The trolley slot 264 is used to extract the fixture trolley 28 from the trolley longitudinal moving device 24 or the trolley transverse moving device 27 and transfer it to the trolley slot 264, so that the staff can check the glass plate 23 in the glass plate fixture 22. The trolley transverse moving device 27 is used for the transverse movement of the fixture trolley 28. The main controller 29 is used to control the trolley longitudinal moving device 24, the coating machine 25, the trolley slot 264, the first trolley transverse moving device 27 and the second trolley transverse moving device 30.

[0107] The working process of the coating reflow section 200 is described as follows: the fixture loading robot 11 places the glass plate fixture 22 on the fixture trolley 28 at the feeding end of the trolley transverse moving line. The fixture trolley 28 is moved by the trolley transverse moving line to the left end of the trolley transverse moving line and is sent into the trolley longitudinal moving device 24 at the left end. The trolley longitudinal moving device 24 transfers the fixture trolley 28 from its front end to the rear end. The trolley longitudinal moving device 24 moves the fixture trolley 28 to the second trolley transverse moving device 30 at the left end of the coating machine 25. The second trolley transverse moving device 30 sends the fixture trolley 28 into the coating machine 25.

The clamp trolley 28 without the glass plate clamp 22 moves to the feed end of the trolley transverse moving line through the first trolley transverse moving device 27 to wait for loading the glass plate clamp 22.

[0108] like Fig.26 and 27 As shown, each first trolley transverse moving device 27 or each second trolley transverse moving device 30 includes a transverse moving base 271, a transverse moving shell 272, a magnetic suspension structure 244, a third roller drive structure 273 and a side guide wheel assembly 274.

The magnetic suspension structure 244 is mounted on the inner top of the transverse moving shell 272, the third roller drive structure 273 is mounted on the top of the transverse moving base 271, and the side guide wheel assembly 274 is mounted on the side wall of the transverse moving shell 272. The upper end of the clamp trolley 28 is magnetically connected to the magnetic suspension structure 244. The lower end of the clamp trolley 28 is movably connected to the third roller drive structure 273.

[0109] The transverse movable base 271 plays a supporting role and is used to install various structures. The transverse movable housing 272 is used to suspend the magnetic suspension structure 244 and the third roller drive structure 273, and plays a protective role for various structures. The magnetic suspension structure 244 generates suction to magnetically support the upper end of the clamp trolley 28. The third roller drive structure 273 is used to drive the clamp trolley 28 to move. The side guide wheel assembly 274 is used to assist the movement of the clamp trolley 28. When the magnetic suspension structure 244 fails, the clamp trolley 28 can be prevented from colliding with the transverse movable housing 272.

The support plate 2731 is vertically connected to the driving base plate 2732. The fourth transmission shaft 2735 is rotatably mounted on the support plate 2731. The four fifth driving wheels 2733 and the four fourth driven synchronous wheels 2734 are respectively mounted on both ends of the four fourth transmission shafts 2735. Each third tension adjustment structure 2736 is respectively mounted between two adjacent fourth driven synchronous wheels 2734. The third driving synchronous wheel 2730 is mounted on the bottom of the driving base plate 2732 through the third driving motor 2739. The two fourth guide wheels 2737 are located between the four fourth driven synchronous wheels 2734 and the third driving synchronous wheel 2730. The third driving synchronous wheel 2730, the four fourth driven synchronous wheels 2734, the three third tension adjustment structures 2736 and the two fourth guide wheels 2737 are connected by a fourth synchronous belt 2738.

[0111] The third driving synchronous wheel 2730 is used to transmit the power of the third driving motor 2739 to the fourth synchronous belt 2738. The support plate 2731 is used to install the third tension adjustment structure 2736 and the fourth transmission shaft 2735. The driving bottom plate 2732 is used to install the support plate 2731 and the third driving motor 2739. The fifth driving wheel 2733 is used to drive the clamp trolley 28 to move. The fourth driven synchronous wheel 2734 is used to transmit the power of the fourth synchronous belt 2738 to the fourth transmission shaft 2735 to achieve synchronous rotation. The fourth transmission shaft 2735 transmits the power of the second driven synchronous wheel 2463 to the fifth driving wheel 2733. The third tension adjustment structure 2736 is used to control the tension of the fourth synchronous belt 2738. The third guide wheel 2649 is used to change the transmission direction of the fourth synchronous belt 2738. The fourth synchronous belt 2738 synchronizes the power of the third driving motor 2739 to the four fourth driven synchronous wheels 2734. The third driving motor 2739 provides power for the rotation of the fifth driving wheel 2733 .

[0112] like Fig.31 As shown, the side guide wheel assembly 274 includes a fixed crossbeam 2741, a plurality of third guide brackets 27421 and a plurality of fifth guide wheels 2743. The plurality of fifth guide wheels 2743 are respectively mounted on the plurality of third guide brackets 27421, and the plurality of third guide brackets 27421 are evenly mounted on the fixed crossbeam 2741. The fixed crossbeam 2741 is mounted on the side inner wall of the transverse movable housing 272. The fifth guide wheel 2743 corresponds to the side of the fixture trolley 28. The fixed crossbeam 2741 is used to evenly distribute the plurality of third guide brackets 27421; the third guide bracket 27421 is used to fix the fifth guide wheel 2743, and the fifth guide wheel 2743 is used to reduce friction.

[0113] The working principle of the first trolley lateral moving device 27 or each second trolley lateral moving device 30 is described as follows: the first suspension frame 2441 and the fourth connecting member 2442 of the magnetic suspension structure 244 are connected obliquely, so that the clamp trolley 28 is in an inclined state, and the weight of the clamp trolley 28 is divided into horizontal force and vertical force. The horizontal force is offset by the magnetic attraction force between the magnetic suspension structure 244 and the upper end of the clamp trolley 28. The magnetic suspension structure 244 and the upper end of the clamp trolley 28 are in a non-contact state, and will not cause wear on the upper end of the clamp trolley 28. The vertical force of the clamp trolley 28 is supported by the third roller drive structure 273, because the magnetic suspension structure 244 bears part of the weight of the clamp trolley 28, reducing the pressure between the clamp trolley 28 and the third roller drive structure 273, thereby reducing the wear on the lower end of the clamp trolley 28. Driven by the third roller drive structure 273, the clamp trolley 28 is driven to move.

[0114] like Figure 32-34As shown, each trolley longitudinal moving device 24 includes a transfer housing 241, a transfer base 242, a bearing frame 243, a magnetic suspension structure 244, a first guide wheel assembly 245, a first roller drive structure 246 and a transfer drive structure 247.

The lower end of the clamp trolley 28 is slidably mounted on the first roller drive structure 246. The first roller drive structure 246 is mounted on the transfer drive structure 247.

[0115] The transfer housing 241 is used to protect the bearing frame 243, the magnetic suspension structure 244, the first guide wheel assembly 245, the first roller drive structure 246 and the transfer drive structure 247 to avoid harm to personnel. The transfer base 242 supports each structure and plays a supporting role. The bearing frame 243 is used to install the magnetic suspension structure 244, the first guide wheel assembly 245, and the first roller drive structure 246. The magnetic suspension structure 244 prevents the upper end of the clamp trolley 28 from directly contacting with the transfer housing 241, avoids the wear of the upper end of the clamp trolley 28, and reduces the pressure of the first roller drive structure 246, thereby reducing the wear of the lower end of the clamp trolley 28. The first guide wheel assembly 245 is used to support the clamp trolley 28 when the magnetic suspension structure 244 fails, so as to prevent the clamp trolley 28 from directly pressing on the transfer housing 241. The first roller drive structure 246 is used to drive the clamp trolley 28 to move horizontally. The transfer driving structure 247 is used to drive the carrying frame 243 to move longitudinally.

[0119] The first suspension frame 2441 is used to suspend the second magnet mounting frame 2443 on the inner top wall of the transfer housing 241. The fourth connecting member 2442 is used to tilt the second magnet mounting frame 2443 at a certain angle and keep a certain distance between the two second magnet mounting frames 2443. The second magnet mounting frame 2443 is used to fix two rows of second magnetic strips 2444. The second magnetic strips 2444 are used to generate suction on both sides of the first magnetic strip 281 to achieve the suspension of the upper end of the clamp trolley 28.
