The square steel material is cut into an appropriate length, and a foot piece and a connecting piece formed by cutting a steel plate are allocated. They are fixed to each other by welding / bolts. A protective mesh plate 2 is provided on the side wall of the beam frame body 11. The cross beam frame and the longitudinal beam frame are fixedly connected to the edge of the protective mesh plate 2 by hinges and bolts. The protective mesh plate 2 is fixed to the side of the machine tool gantry support 1, thereby forming a protective net to prevent the feeding device from causing damage to surrounding personnel due to accidents during the feeding process. In the event of a situation where a transmission rack Ⅰ12 is fixedly disposed on both sides of the top of the beam body 11, a transmission slide rail Ⅰ16 is disposed on one side of the transmission rack Ⅰ12, the transmission rack Ⅰ12 is arranged in parallel with the transmission slide rail Ⅰ16, a moving mechanism 13 is movably disposed on the top of the transmission rack Ⅰ12, the moving mechanism 13 moves laterally along the transmission slide rail Ⅰ16 to form an X-axis moving channel, the machine tool gantry bracket 1 also includes a drag chain trough Ⅰ14, a bracket Ⅰ17 adapted to the size of the drag chain trough Ⅰ14 is also fixedly disposed on the top of the beam body 11, and photoelectric sensors Ⅰ15 are fixedly disposed on both ends of the transmission rack Ⅰ12; like Figure 5-6 The moving mechanism 13 includes a carrying plate 131, a transmission motor Ⅰ132 is fixedly arranged on the top of the carrying plate 131, a rotating gear Ⅰ133 is arranged at the bottom of the carrying plate 131, an output shaft of the transmission motor Ⅰ132 passes through the carrying plate 131 and is connected to the rotating gear Ⅰ133, the rotating gear Ⅰ133 is meshed with the edge of the transmission rack Ⅰ12 for transmission, a limiting slider 134 is also fixedly arranged at the bottom of the carrying plate 131, a slide groove is opened on the limiting slider 134, and the limiting slider 134 is slidably connected with the transmission slide rail Ⅰ16 through the slide groove; Specifically, the multi-channel feeding mechanism 3 fixedly assembled with the load-carrying plate 131 is driven by the operation of the driving motor I 132 to drive the rotation of the rotating gear I 133. Through the meshing transmission between the rotating gear I 133 and the driving rack I 12, and the limiting sliding connection between the limiting slider 134 and the driving slide rail I 16, the stable operation state of the moving mechanism 13 on the top of the beam frame body 11 is maintained. By adjusting the forward and reverse rotation of the driving motor I 132, the reciprocating movement of the moving mechanism 13 is realized, forming an X-axis moving channel. Among them, combined with the externally designed truss PLC controller, the photoelectric sensor I 15 monitors the X-axis moving displacement size of the moving mechanism 13. Combined with the setting of the drag chain wire groove I 14, the wires connecting the driving motor I 132 and the photoelectric sensor I 15 to the outside can be stored, so as to protect the cables during the movement of the moving mechanism 13. When the drag chain wire groove I 14 follows the movement of the moving mechanism 13, it is wound and extended at the bracket I 17 position; As Figure 7-8 , the multi-channel feeding mechanism 3 includes a Y-axis moving component 31. Both sides of the Y-axis moving component 31 are provided with Z-axis moving components 32. The bottom of the Z-axis moving component 32 is provided with a material rack support 33.

Fixed plates I 312 are fixedly arranged at the bottoms of both ends of the Y-axis main beam 311. The Y-axis main beam 311 is fixed to the top of the load-carrying plate 131 through the fixed plates I 312 and bolts. A C-shaped frame I 313 is sleeved outside the Y-axis main beam 311. A driving motor II 314 is fixedly arranged at the top of the C-shaped frame I 313.

A driving rack II 317 and a driving slide rail II 319 are fixedly arranged on the outer wall of the Y-axis main beam 311. The corresponding limiting slider 134 of the C-shaped frame I 313 is slidably connected with the driving slide rail II 319 through the sliding groove, and the rotating gear II is in meshing transmission with the driving rack II 317. The Y-axis moving component 31 also includes a drag chain wire groove II 315. A bracket II 316 adapted to the size of the drag chain wire groove II 315 is also fixedly arranged on one side of the Y-axis main beam 311. Photoelectric sensors II 318 are arranged at both ends of the driving rack II 317; Specifically, the overall multi-channel loading mechanism 3 is assembled on the corresponding carrier plate 131 position of the machine tool gantry bracket 1 by the fixing plate I 312. The two side panels of the C-shaped frame I 313 are fixedly connected to the Z-axis moving component 32. The driving motor II 314 drives the rotation of the rotating gear II. Through the meshing transmission between the rotating gear II and the driving rack II 317, and the limiting sliding connection between the corresponding limiting slider 134 of the C-shaped frame I 313 and the driving slide rail II 319, a stable operating state of the C-shaped frame I 313 (Y-axis moving mechanism) on the Y-axis main beam 311 is formed. By adjusting the forward and reverse rotation of the driving motor II 314, the reciprocating movement of the C-shaped frame I 313 is realized, forming a Y-axis moving channel. The photoelectric sensor II 318 monitors the Y-axis moving displacement size of the C-shaped frame I 313, and the cable is protected in combination with the drag chain cable groove II 315, so that the drag chain cable groove II 315 is wound and extended at the bracket II 316 position; As Figure 10-12 shown, the Z-axis moving component 32 includes a Z-axis main beam 321. A driving rack III 323 and a driving slide rail III 322 are fixedly arranged on the outer wall of the Z-axis main beam 321. A C-shaped frame II 324 is also sleeved outside the Z-axis main beam 321. A driving motor III 325 is fixedly arranged on the outer wall of the C-shaped frame II 324. A fixing plate II 326 is fixedly arranged on one side of the C-shaped frame II 324 away from the driving motor III 325.

A limiting slider 134 is fixedly arranged on the inner wall of the C-shaped frame II 324. A chute is formed on the limiting slider 134. The corresponding limiting slider 134 of the C-shaped frame II 324 is slidably connected with the driving slide rail III 322 through the chute, and the rotating gear III is in meshing transmission with the driving rack III 323. A drag chain cable groove III 327 is also arranged on the outer wall of the C-shaped frame II 324, and photoelectric sensors III are arranged at both ends of the driving rack III 323. An outer connecting plate I 328 is fixedly arranged on the outer wall of the C-shaped frame II 324, and an outer connecting plate II 329 is fixedly arranged at the bottom end of the Z-axis main beam 321; Specifically, the overall Z-axis moving component 32 is assembled on the side wall of the C-shaped frame I 313 by the fixing plate II 326. The driving motor III 325 drives the rotation of the rotating gear III. Through the meshing transmission between the rotating gear III and the driving rack III 323, and the limiting sliding connection between the corresponding limiting slider 134 of the C-shaped frame II 324 and the driving slide rail III 322, a stable operating state of the Z-axis main beam 321 moving along the Z-axis is formed. By adjusting the forward and reverse rotation of the driving motor III 325, the Z-axis reciprocating movement of the Z-axis main beam 321 along the C-shaped frame II 324 is realized, forming a Z-axis moving channel, and the cable is protected in combination with the drag chain cable groove III 327; The specific implementation method is as follows: After loading the silicon ingot raw material on the material rack support 33, the position of material transfer is input into the truss PLC controller, so that the multi-channel feeding mechanism 3 starts to work. Through the three-way position movement of the X-axis movement channel, Y-axis movement channel and Z-axis movement channel, the material rack support 33 drives the raw material to be transported to the storage location within the range of the beam body 11 along the set movement route. The detection values of the photoelectric sensor I 15, photoelectric sensor II 318 and photoelectric sensor III are recorded by the truss PLC controller to ensure the accuracy of the displacement of the material rack support 33 in the X, Y and Z axes, and to ensure the accuracy of the loading position of this gantry truss.

[0032] Embodiment 2:

[0033] Based on the multi-channel feeding mechanism 3 proposed in Embodiment 1, the present invention provides further technical solutions for the material rack support 33, the crystal support position compensation component 34 and the gripper assembly 35.

[0034] Please refer to Fig.10 、 Figure 13-14 The material rack support 33 provided by the present invention includes a crystal support frame 331. Jack holes 332 are provided on both sides of the crystal support frame 331. A U-shaped identification frame 333 is fixedly provided on the top of the crystal support frame 331. The U-shaped identification frame 333 is designed to be brightly colored or made of a material that is easy to be recognized by the digital camera 345 for the geometric parameters and surface quality of the workpiece. A bearing bottom plate 334 is fixedly provided at the bottom of the crystal support frame 331. A material silicon ingot 335 is provided on the top of the bearing bottom plate 334; a support plate 336 is provided on the top of the bearing bottom plate 334. A limit connection block 337 is provided between the bearing bottom plate 334 and the support plate 336. The bearing bottom plate 334, the support plate 336 and the limit connection block 337 are fixed by bolts. The limit connection block 337 is set as a wedge-shaped block with an outer height and an inner low height; Specifically, the material silicon ingot 335 is placed on the top of the support plate 336 inside the crystal support frame 331. The support plate 336 is lifted to the height of the opening side of the crystal support frame 331 by the limit connection block 337, so that the top surface of the support plate 336 is set as an inclined surface (the inclination angle is set to 15°-30°). The horizontally arranged bearing bottom plate 334 ensures the placement stability of the material rack support 33. Moreover, the angle-lifted support plate 336 prevents the material silicon ingot 335 from detaching from the material rack support 33 due to inertia during the movement / braking of the multi-channel feeding mechanism 3, ensuring the stability of the material rack support 33 during the loading and transfer of the material silicon ingot 335; Such as Fig.16As shown in the figure, the crystal carrier position compensation component 34 includes a loading rack 341. The loading rack 341 is fixedly connected to the outer connecting plate I 328 by bolts. One end of the loading rack 341 is fixedly provided with a T-shaped connecting rack 342. A counterweight plate 344 is further provided at the bottom of the T-shaped connecting rack 342. A bogie 343 is fixedly provided at the top of the counterweight plate 344; the bogie 343 is rotatably connected to the T-shaped connecting rack 342, and angle marking lines are also provided on the outer wall of the T-shaped connecting rack 342. A digital camera 345 is also installed on the loading rack 341; Specifically, during the movement of the multi-channel feeding mechanism 3, the digital camera 345 photographs the working position placement state of the material rack support 33 placed at the position of the beam frame body 11, so as to obtain a high-precision measurement result through the optical imaging and digital processing technology of the digital camera 345, so as to accurately record and judge the placement position of the material rack support 33. During this period, the counterweight plate 344 limits the shooting edge of the digital camera 345 (because the outer part blocked by the digital camera 345 cannot be photographed). The edge of the counterweight plate 344 is aligned with the U-shaped marking frame 333 at the top of the material rack support 33, so as to accurately compare the standard placement state of the material rack support 33. If the initial placement position of the material rack support 33 is tilted, and the counterweight plate 344 applies a force limit and push to the edge of the material rack support 33 during the grasping process, it enables the subsequent grasping component 35 to smoothly grasp the material rack support 33; Moreover, when the grasping component 35 grasps the material rack support 33 and moves along with the multi-channel feeding mechanism 3, because the crystal carrier position compensation component 34 is integrated with the outer connecting plate I 328, when the inertial force generated by the movement braking of the multi-channel feeding mechanism 3 acts, the counterweight plate 344 together with the bogie 343 swings reciprocally within a small range along the T-shaped connecting rack 342. The reciprocal swing of the counterweight plate 344 cancels out the swing with the material rack support 33 loaded with the silicon ingot 335, so as to further reduce the protection and anti-drop of the collaborative pallet 336 to the silicon ingot 335; Based on the above structure, the user regularly calibrates the position of the counterweight plate 344 according to the angle marking lines on the outer wall of the T-shaped connecting rack 342, so as to facilitate the subsequent accurate operation of the device; Such as Fig.15As shown in the figure, the gripper frame assembly 35 includes an upper loading plate 351 and a lower loading plate 352. Telescopic frames 353 are provided at both ends of the upper loading plate 351 and the lower loading plate 352.

The output shaft of the drive motor IV 354 penetrates the upper loading plate 351 and acts on the double-acting cylinder 355. Clamping arms 356 are connected to both output shafts on both sides of the double-acting cylinder 355. A clamping post 357 is fixedly provided on one side of the bottom end of the clamping arm 356. A limit adjustment groove 358 is opened at the connection between the bottom of the clamping arm 356 and the lower loading plate 352; the drive motor IV 354 is connected to the outer connecting plate II 329 by bolts. The width of the limit adjustment groove 358 is equivalent to the width of the lower loading plate 352, and the height of the limit adjustment groove 358 is greater than the thickness of the lower loading plate 352; the telescopic frame 353 includes a shaft rod, a shaft valve plug, and a telescopic spring. The telescopic spring is sleeved outside the shaft rod. The shortening of the distance between the upper loading plate 351 and the lower loading plate 352 drives the contraction of the length of the telescopic spring, and drives the top end of the shaft rod to extend from the top end of the shaft valve plug at the top.

[0035] The specific implementation method is as follows: When using the gripper frame assembly 35 to grasp and release the material rack support 33 loaded with the material silicon ingot 335, the multi-channel feeding mechanism 3 moves to transport the gripper frame assembly 35 to the position of the externally placed material rack support 33. The lower loading plate 352 is pressed onto the top of the U-shaped identification frame 333. The length of the telescopic frame 353 contracts, so that the lower loading plate 352 adjusts its longitudinal position along the limit adjustment groove 358. Under the action of the resilience of the telescopic frame 353, the lower loading plate 352 presses down the material rack support 33 to prevent the angular deviation of the position of the material rack support 33 during the operation of the gripper frame assembly 35 from affecting the clamping effect. During this period, the bottoms of the two clamping arms 356 are placed at the middle of the top end of the crystal support frame 331. The drive motor IV 354 works to drive the double-acting cylinder 355 to extend, driving the distance between the two clamping arms 356 to increase. The clamping post 357 is inserted into the jack 332 position. The clamping arm 356 ensures the lateral position limitation of the crystal support frame 331, while the telescopic frame 353 together with the lower loading plate 352 realizes the longitudinal position limitation of the crystal support frame 331, thereby ensuring a stable clamping effect; After the multi-channel feeding mechanism 3 works to move the material rack support 33 to the processing position, the drive motor IV 354 works to drive the double-acting cylinder 355 to contract, driving the distance between the two clamping arms 356 to decrease. The clamping post 357 is withdrawn from the jack 332 position. The Z-axis moving channel of the multi-channel feeding mechanism 3 drives the gripper frame assembly 35 to lift in height, releasing the pressing of the lower loading plate 352 on the material rack support 33, thereby completing the discharging process of the material rack support 33.
