Description

Technical Field

[0001] The invention relates to the technical field of feeding gantry trusses, and more specifically to a three-channel automatic feeding gantry truss assembly. Background Art

[0002] With the continuous advancement of science and technology, the demand for silicon wafers in the traditional photovoltaic industry and equipment processing as well as the semiconductor or chip preparation industry is constantly increasing. The silicon ingot is sliced ​​using a slicing machine to process the silicon ingot raw material into silicon wafers. Silicon is a semiconductor material and its own conductivity is not very good. However, its resistivity can be precisely controlled by adding appropriate dopants. Before manufacturing semiconductors, silicon must be converted into wafers. Single crystal silicon is a solid formed by atoms in a three-dimensional spatial pattern periodically, and this pattern runs through the entire material. Polycrystalline silicon is formed by many small single crystals with different crystal orientations and cannot be used to make semiconductor circuits. Polycrystalline silicon must be melted into single crystals before it can be processed into wafers used in semiconductor applications.

[0003] When processing silicon ingots, the cooperation of the gantry truss is required to achieve high-precision and stable operation of the silicon ingot raw materials. However, due to the self-weight and surface smoothness of the silicon crystal, it is easy to cause low-frequency elastic vibration when it stops moving during the actual feeding process, which may cause the material to fall, resulting in processing safety accidents or damage to the production raw materials.

[0023] Technical effects and advantages of the present invention:

[0024] In the present invention, the top surface of the pallet inside the material rack support is set as an inclined surface, which ensures the placement stability of the material rack support, avoids the silicon ingot of the material falling off the material rack support due to inertia during the braking of the multi-channel feeding mechanism, and when the gripper assembly grabs the material rack support and moves along with the multi-channel feeding mechanism, the counterweight plate together with the bogie swings reciprocally within a small range along the T-shaped connecting frame. The reciprocal swing of the counterweight plate cancels out the inertial swing of the material rack support loaded with the silicon ingot of the material, thereby further reducing the protection and anti-dropping of the collaborative pallet for the silicon ingot of the material;

[0025] In the present invention, the digital camera photographs the placement state of the material rack support placed at the position of the beam frame body, accurately records and judges the placement station of the material rack support, and aligns the edge of the counterweight plate with the C-shaped identification frame at the top of the material rack support, so as to accurately compare the standard placement state of the material rack support;

[0026] In the present invention, the multi-channel feeding mechanism moves to transport the gripper assembly to the position of the externally placed material rack support. The lower loading plate presses down the material rack support, and the drive motor Ⅳ works to drive the double-axis oil cylinder to extend and the clamping column to insert into the jack position. The clamping arm ensures the lateral position limitation of the crystal pallet frame, thereby ensuring a stable clamping effect;

[0027] In the present invention, when the multi-channel feeding mechanism 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 detection values of the photoelectric sensor Ⅰ, photoelectric sensor Ⅱ, and photoelectric sensor Ⅲ ensure the accuracy of the displacement of the material rack support in the X, Y, and Z axes, ensure the accuracy of the loading position of the gantry truss, and improve the processing efficiency.

[0054] Embodiment 1:

[0055] The present invention provides a three-channel automatic loading gantry truss assembly as Figure 1-12 shown, including a machine tool gantry bracket 1, on which a multi-channel loading mechanism 3 is movably arranged. The combination of the machine tool gantry bracket 1 and the multi-channel loading mechanism 3 realizes the body position movement in the X, Y, and Z three axial directions;

[0056] As Figure 3-4The machine tool gantry support 1 includes a beam frame body 11, and the beam frame body 11 includes a cross beam frame, a longitudinal beam frame and a reinforcing rib beam frame. 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;

[0057] 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;

[0058] Specifically, the multi-channel feeding mechanism 3 fixedly assembled with the carrying plate 131 is driven by the transmission motor Ⅰ132 to rotate the rotating gear Ⅰ133, and the rotating gear Ⅰ133 is meshed with the transmission rack Ⅰ12, and the limiting sliding connection between the limiting slider 134 and the transmission slide rail Ⅰ16 is formed, so that the stable operation state of the moving mechanism 13 on the top of the beam frame body 11 is maintained, and the reciprocating movement of the moving mechanism 13 is achieved by adjusting the positive and negative rotation of the transmission motor Ⅰ132 to form an X-axis moving channel, wherein, in combination with the externally designed truss PLC controller, the X-axis movement displacement size of the moving mechanism 13 is monitored by the photoelectric sensor Ⅰ15, and in combination with the setting of the drag chain trough Ⅰ14, the transmission motor Ⅰ132 and the photoelectric sensor Ⅰ15 and the externally connected wires can be stored, so that the cables are protected during the movement of the moving mechanism 13, and the drag chain trough Ⅰ14 is wound and stretched at the bracket Ⅰ17 position when following the movement of the moving mechanism 13;

[0059] like Figure 7-8, the multi-channel loading mechanism 3 includes a Y-axis moving component 31. On both sides of the Y-axis moving component 31, there are Z-axis moving components 32. At the bottom of the Z-axis moving component 32, there is a material rack support 33. Between the Z-axis moving components 32, there is a gripper frame assembly 35. On one side of the Z-axis moving component 32, there is also a crystal holder position compensation component 34, which adjusts the placement position of the material rack support 33;

[0060] As Fig. 9 shown in the figure, the Y-axis moving component 31 includes a Y-axis main beam 311. At the bottom of both ends of the Y-axis main beam 311, there are fixed fixing plates I 312. The Y-axis main beam 311 is fixed to the top of the carrier plate 131 through the fixing plates I 312 and bolts. Outside the Y-axis main beam 311, there is a C-shaped frame I 313 sleeved. At the top of the C-shaped frame I 313, there is a driving motor II 314. The output shaft of the driving motor II 314 penetrates through the C-shaped frame I 313 and is connected with a rotating gear II inside. And at the inner wall of the C-shaped frame I 313, there is a fixed limit slider 134, and a chute is opened on the limit slider 134; On the outer wall of the Y-axis main beam 311, there are fixed a driving rack II 317 and a driving slide rail II 319. The corresponding limit slider 134 of the C-shaped frame I 313 is slidably connected with the driving slide rail II 319 through the chute, and the rotating gear II is meshed with the driving rack II 317 for transmission; The Y-axis moving component 31 also includes a drag chain wire groove II 315.

At both ends of the driving rack II 317, there are photoelectric sensors II 318;

[0061] 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 solid connection between the C-shaped frame I 313 and the Z-axis moving component 32 is realized by the two side panels of the C-shaped frame I 313. The rotation of the rotating gear II is driven by the operation of the driving motor II 314. Through the meshing transmission between the rotating gear II and the driving rack II 317, and the limit sliding connection between the corresponding limit slider 134 of the C-shaped frame I 313 and the driving slide rail II 319, a stable running 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 Y-axis moving displacement size of the C-shaped frame I 313 is monitored by the photoelectric sensor II 318, and the cable is protected in combination with the drag chain wire groove II 315, so that the drag chain wire groove II 315 is wound and extended at the position of the bracket II 316;

[0062] As Figure 10-12As shown in the figure, the Z-axis moving component 32 includes a Z-axis main beam 321. A transmission rack III 323 and a transmission slide rail III 322 are fixedly arranged on the outer wall of the Z-axis main beam 321. An inverted U-shaped frame II 324 is also sleeved outside the Z-axis main beam 321. A transmission motor III 325 is fixedly arranged on the outer wall of the inverted U-shaped frame II 324. A fixed plate II 326 is fixedly arranged on one side of the inverted U-shaped frame II 324 away from the transmission motor III. The output shaft of the transmission motor III penetrates through the inverted U-shaped frame II 324 and is connected with a rotating gear III inside. And a limiting slider 134 is fixedly arranged on the inner wall of the inverted U-shaped frame II 324. A chute is arranged on the limiting slider 134. The corresponding limiting slider 134 of the inverted U-shaped frame II 324 is slidably connected with the transmission slide rail III 322 through the chute. The rotating gear III is in meshing transmission with the transmission rack III 323. A drag chain wire groove III 327 is also arranged on the outer wall of the inverted U-shaped frame II 324. And photoelectric sensors III are arranged at both ends of the transmission rack III 323. An external connecting plate I 328 is also fixedly arranged on the outer wall of the inverted U-shaped frame II 324. An external connecting plate II 329 is fixedly arranged at the bottom end of the Z-axis main beam 321.

[0063] Specifically, the overall Z-axis moving component 32 is assembled on the side wall of the inverted U-shaped frame I 313 by the fixed plate II 326. The transmission motor III 325 works to drive the rotation of the rotating gear III. Through the meshing transmission between the rotating gear III and the transmission rack III 323, and the limiting sliding connection between the corresponding limiting slider 134 of the inverted U-shaped frame II 324 and the transmission slide rail III 322, a stable running state of the Z-axis main beam 321 moving along the Z-axis is formed. By adjusting the forward and reverse rotation of the transmission motor III 325, the Z-axis main beam 321 reciprocates along the Z-axis of the inverted U-shaped frame II 324 to form a Z-axis moving channel, and the cable is protected in combination with the drag chain wire groove III 327.

[0064] The specific implementation method is as follows: After loading the silicon ingot raw material at the position of the material rack support 33, the position of the material transfer body is input into the truss PLC controller, so that the multi-channel feeding mechanism 3 starts to work. Through the three-way body position movement of the X-axis moving channel, the Y-axis moving channel and the Z-axis moving 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 moving route. The detection values of the photoelectric sensor I 15, the photoelectric sensor II 318 and the 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 body position of the gantry truss feeding.

[0065] Embodiment 2:

[0066] 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 body position compensation component 34 and the gripper component 35.

[0067] Please refer to Fig.10 、 Figure 13-14, the material rack support 33 provided by the present invention includes a crystal support frame 331. Jacks 332 are provided on both sides of the crystal support frame 331. A U-shaped identification frame 333 is fixedly provided at 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 easily 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;

[0068] 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 a height on 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;

[0069] As Fig.16 shown, the crystal support position compensation assembly 34 includes a loading rack 341. The loading rack 341 is fixedly connected to the outer connecting plate I 328 by bolts. A T-shaped connecting rack 342 is fixedly provided at one end of the loading rack 341. A counterweight plate 344 is further provided at the bottom of the T-shaped connecting rack 342. A steering rack 343 is fixedly provided at the top end of the counterweight plate 344; the steering rack 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;

[0070] Specifically, during the movement of the multi-channel feeding mechanism 3, the digital camera 345 captures the 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, thereby accurately recording and judging 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 identification frame 333 at the top of the material rack support 33, so as to accurately compare with the standard placement state of the material rack support 33. If the initial placement position of the material rack support 33 is inclined, and the counterweight plate 344 applies a force-limiting push to the edge of the material rack support 33 during the grasping process, it enables the subsequent grasping component 35 to smoothly perform the grasping work on the material rack support 33;

[0071] When the grabber assembly 35 grabs the material rack 33 and follows the movement of the multi-channel feeding mechanism 3, because the crystal rack position compensation assembly 34 is integrated with the external connecting plate I 328, when the multi-channel feeding mechanism 3 is subjected to inertial force generated by the movement and braking, the counterweight plate 344 and the bogie 343 swing back and forth in a small range along the T-shaped connecting frame 342, and the reciprocating swing of the counterweight plate 344 and the swing of the material rack 33 loaded with the material silicon ingot 335 are offset, thereby further reducing the protection and anti-dropping of the coordinated support plate 336 on the material silicon ingot 335; based on the above structure, the user regularly calibrates the position of the counterweight plate 344 according to the angle marking pattern on the outer wall of the T-shaped connecting frame 342, so as to facilitate the subsequent precise operation of the device;

[0072] like Fig.15 As shown, the grab frame assembly 35 includes an upper loading plate 351 and a lower loading plate 352, and telescopic frames 353 are provided at both ends of the upper loading plate 351 and the lower loading plate 352. A transmission motor IV 354 is provided at the center of the top of the upper loading plate 351, and a double-axis oil cylinder 355 is provided at the center of the bottom of the upper loading plate 351. The output shaft of the transmission motor IV 354 penetrates the upper loading plate 351 and acts on the double-axis oil cylinder 355. The output shafts on both sides of the double-axis oil cylinder 355 are connected to clamping arms 356, and a clamping column 357 is fixedly provided on one side of the bottom end of the clamping arm 356. A limit adjustment groove 358 is provided at the connection between the bottom and the download plate 352; the transmission motor IV 354 is connected to the external connection plate II 329 by bolts, the width of the limit adjustment groove 358 is equivalent to the width of the download plate 352, and the height of the limit adjustment groove 358 is greater than the thickness of the download plate 352; the telescopic frame 353 includes a shaft rod, a shaft valve plug and a telescopic spring, the telescopic spring is sleeved on the outside of the shaft rod, and the shortening of the distance between the upper loading plate 351 and the download plate 352 drives the length of the telescopic spring to shrink, and drives the top end of the shaft rod to extend from the top end of the shaft valve plug at the top.

[0073] The implementation method is specifically as follows: When using the gripper frame assembly 35 to grip 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 download 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 download plate 352 adjusts its longitudinal position along the limit adjustment groove 358. Under the action of the resilience of the telescopic frame 353, the download plate 352 presses down on the material rack support 33 to prevent the angular deviation of the material rack support 33 during the operation of the gripper frame assembly 35, which affects 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-axis oil 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 download plate 352 realizes the longitudinal position limitation of the crystal support frame 331, thus ensuring a stable clamping effect;

[0074] 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-axis oil 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 download plate 352 on the material rack support 33, thereby completing the discharging process of the material rack support 33.
