[0002] In the process of photovoltaic material production, the sheet material is usually loaded into a carrier, and then the carrier is sent to a reaction device to react and process the sheet material. Before sending the carrier into the reaction device, multiple carriers need to be placed on the carrier table at intervals. Before moving the carrier, the arrangement direction of the multiple carriers is inconsistent with the extension direction of the carrier table, so the direction of the carrier needs to be rotated horizontally. At the same time, because the carrier table of some equipment is tilted, the carrier also needs to be flipped vertically. The existing clamping mechanism is not convenient for placing the carrier on the carrier table. Utility Model Content

[0071] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0072] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "upper", "lower", "front", "back" and similar expressions used herein are for illustrative purposes only.

[0073] The terms "first", "second", etc. are only used to distinguish different objects and shall not be understood as indicating or implying relative importance or implying the quantity, specific order or primary and secondary relationship of the indicated technical features.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0075] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0076] The first direction X and the third direction Z are directions on a horizontal plane, the second direction Y is parallel to the gravity direction, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0077] In other embodiments, the first direction X and the third direction Z are directions that are at any angle to the horizontal plane, and the second direction Y is at an angle to the gravity direction.

[0078] In some embodiments, see Figure 1 and Figure 2 The present application discloses a photovoltaic material processing device 100, comprising a reaction device 50, a carrier platform 30 and a clamping mechanism 10. Before processing, the clamping mechanism 10 clamps and places a plurality of carriers 20 carrying sheet materials 40 on the carrier platform 30, and the carrier platform 30 then carries a plurality of carriers 20 into the reaction device 50 for reaction processing. When the sheet materials 40 are processed, the carrier platform 30 carries a plurality of carriers 20 and moves them out of the reaction device 50, and the clamping mechanism 10 then removes the carriers 20 from the carrier platform 30.

[0079] Since the arrangement direction of the plurality of carriers 20 is inconsistent with the extension direction of the carrier platform 30, please refer to Figure 2, and the top surface of the carrier 30 is inclined. The clamping mechanism 10 rotates the carrier 20 in the horizontal direction so that the arrangement direction of the carrier 20 is consistent with the extension direction of the carrier 30. At the same time, the clamping mechanism 10 flips the carrier 20 in the vertical direction so that the bottom surface of the carrier 20 is parallel to the top surface of the carrier 30, so that the bottom surface of the carrier 20 and the top surface of the carrier 30 are in uniform contact, which helps to reduce the risk of partial contact of the carrier 20 with the carrier 30 first, resulting in excessive local stress on the carrier 20 and causing the carrier 20 to break.

[0080] In some embodiments, see Figure 2 The top surface of the support platform 30 is set at an angle A with the horizontal plane, and the angle A is 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5° or 5°, wherein, Figure 2 The B line in the figure indicates the horizontal line.

[0081] In some embodiments, the sheet material 40 is a photovoltaic material such as a silicon wafer or a solar cell.

[0082] In some embodiments, the carrier 20 is a carrier tool such as a flower basket, a graphite boat, or a graphite frame.

[0083] In some embodiments, see Figure 3 and Figure 4 The clamping mechanism 10 includes: a rotating assembly 14, a translation assembly 13, two flip assemblies 12 and two clamping assemblies 11. The rotating assembly 14 includes a rotating driver 141 and a mounting frame 142, the rotating driver 141 is connected to the translation assembly 13 and the mounting frame 142 respectively, the two flip assemblies 12 are connected to the translation assembly 13 respectively, and one clamping assembly 11 is connected to one flip assembly 12. Before the clamping mechanism 10 clamps the external carrier 20, an external force drives the mounting frame 142 to move, so that the mounting frame 142 drives the translation component 13, the flip component 12 and the clamping component 11 to move, and the translation component 13 drives the two flip components 12 to move relative to each other, so that the flip components 12 respectively drive the corresponding clamping components 11 to move, thereby adjusting the distance between the two clamping components 11, so that the two clamping components 11 are aligned one by one with two of the arranged carriers 20, and the external force drives the mounting frame 142 to move downward, so that the carrier 20 is located in the clamping area of ​​the clamping component 11, thereby achieving the effect of the two clamping components 11 accurately clamping the carrier 20.

[0084] After the two clamping assemblies 11 clamp the two carriers 20, the external force drives the mounting frame 142 to move closer to the carrier platform 30, and the rotary driver 141 drives the translation assembly 13 to drive the flip assembly 12 and the clamping assembly 11 to rotate relative to the mounting frame 142 around the second rotation axis. Thus, the arrangement direction of the two carriers 20 is consistent with the extension direction of the carrier platform 30, each flip assembly 12 drives the clamping assembly 11 to rotate relative to the translation assembly 13 around the first rotation axis, and the clamping assembly 11 drives the carrier 20 to rotate the angle A, so that the bottom surface of the carrier 20 is parallel to the bottom surface of the carrier platform 30. At the same time, the translation assembly 13 drives the flip assembly 12 to drive the two clamping assemblies 11 to move, so that the clamping assembly 11 drives the carrier 20 to move, so as to adjust the relative distance between the two carriers 20, so as to achieve the effect of arranging the carriers 20 at a specified interval, so as to meet the processing requirements of the reaction device 50. The external force causes the mounting frame 142 to move downward, and the clamping assembly 11 releases the carrier 20, so that the clamping mechanism 10 places the carrier 20 on the carrier platform 30. The first rotation axis is parallel to the first direction X, and the second rotation axis is parallel to the second direction Y.

[0085] Since the translation component 13 rotates around the second rotation axis, and the second rotation axis rotates in a direction parallel to the second direction Y, the first direction X and the third direction Z can be changed. It should be noted that the third direction Z is always parallel to the direction in which the translation component 13 drives the flip component 12 to move.

[0086] In addition, compared with the method of using a robot arm, the use of the clamping mechanism 10 helps to reduce the cost of the photovoltaic material processing equipment 100.

[0087] In some embodiments, when a whole sheet material 40 is divided into two halves, two clamping assemblies 11 respectively clamp the two halves of the same whole sheet material 40 , thereby achieving the effect of the photovoltaic material processing equipment 100 quickly processing two halves of the sheet material 40 .

[0088] In other embodiments, the two clamping assemblies 11 may also clamp two whole sheets of sheet material 40 respectively.

[0089] In other embodiments, the number of the clamping components 11 and the flipping components 12 of the clamping mechanism 10 is three, four or more, respectively, so that the clamping mechanism 10 can clamp a plurality of carriers 20 at the same time.

[0090] In other embodiments, the number of the clamping assemblies 11 may be three or more, and the number of the flipping assemblies 12 is consistent with the number of the clamping assemblies 11, thereby achieving the effect of the clamping mechanism 10 loading and unloading multiple carriers 20 at the same time.

[0091] In some embodiments, the rotation driver 141 is a motor disposed on a mounting bracket 142, and a reducer (not marked) is also disposed on the mounting bracket 142. The motor is connected to the translation assembly 13 through the reducer to reduce the rotation speed of the translation assembly 13 driven by the rotation driver 141, thereby facilitating the control of the rotation angle of the translation assembly 13.

[0092] In some embodiments, see Figure 4 The translation assembly 13 includes a slide rail 131, a slider 132 and a translation driver 133. The slide rail 131 extends along the third direction Z. The number of the sliders 132 is the same as the number of the flipping assemblies 12. Each slider 132 is arranged at the bottom of the slide rail 131 and is slidably connected to the slide rail 131 respectively. Each slider 132 is also connected to a translation driver 133 and a flipping assembly 12 respectively. The translation driver 133 drives the corresponding slider 132 to drive the flipping assembly 12 to reciprocate along the third direction Z on the slide rail 131, so that the flipping assembly 12 drives the clamping assembly 11 to reciprocate in the third direction Z, thereby achieving the effect of adjusting the spacing of the carrier 20.

[0093] In some embodiments, see Figure 4 The translation driver 133 is a synchronous belt 1332 and a synchronous motor 1331. The synchronous belt 1332 is connected to the corresponding slider 132. The synchronous motor 1331 drives the synchronous belt 1332 to rotate on the slide rail 131, and the synchronous belt 1332 drives the slider 132 to reciprocate along the third direction Z.

[0094] In other embodiments, the translation driver 133 is a power device having an output reciprocating force, such as a screw module, an electric pusher, a linear motor, or a telescopic cylinder.

[0095] In some embodiments, see Figure 4 and Figure 5 Each flip assembly 12 includes a flip member 121 and a flip driver 122. The flip member 121 is fixedly connected to the clamping assembly 11, and the flip member 121 is also rotatably connected to the slider 132. Each flip driver 122 is connected to the slider 132. The flip driver 122 drives the corresponding flip member 121 to rotate relative to the slider 132, and the flip member 121 drives the clamping assembly 11 to rotate around the first rotation axis, so that the flip assembly 12 drives the clamping assembly 11 to adjust the tilt angle of the carrier 20.

[0096] In some embodiments, see Figure 5 and Figure 6The flip member 121 is a plate-shaped structure, a first ear 1215 is provided on the top of the flip member 121, and a second ear 1321 is provided on the bottom of the slider 132. The first ear 1215 and the second ear 1321 are rotatably connected, thereby extending the distance between the flip member 121 and the slider 132. When the flip member 121 rotates relative to the slider 132, it helps to reduce the risk of interference between the flip member 121 and the slider 132.

[0097] In some embodiments, the flipping driver 122 includes an electric motor (not shown), the stator of the electric motor is fixedly connected to the second support ear 1321, and the mover of the electric motor is fixedly connected to the first support ear 1215. When the stator is energized, the mover drives the first support ear 1215 to rotate, and the first support ear 1215 drives the flipping member 121 to rotate relative to the slider 132.

[0098] For further information, see Figure 6 The flip actuator 122 includes a cylinder 1221 and a telescopic rod 1222 that are movably connected to each other. One end of the cylinder 1221 away from the telescopic rod 1222 is rotatably connected to the bottom of the slider 132, and the cylinder 1221 is located on one side of the second ear 1321 along the third direction Z. One end of the telescopic rod 1222 away from the cylinder 1221 (hereinafter referred to as the end of the telescopic rod 1222) is rotatably connected to the edge of the top of the flip member 121, so that the telescopic rod 1222 is arranged crosswise with the second direction Y. Compressed gas or hydraulic oil is introduced into the cylinder 1221 to push the telescopic rod 1222 to extend and retract. The telescopic rod 1222 acts on the edge of the flip member 121 so that the flip member 121 rotates with the first ear 1215 as a fulcrum, thereby using the lever principle to reduce the output force of the flip actuator 122 relative to the drive of the motor. In addition, the telescopic rod 1222 is connected to the edge of the flip member 121 to increase the distance between the end of the telescopic rod 1222 and the first ear 1215, that is, the rotation radius of the end of the telescopic rod 1222 with the first ear 1215 as the center is increased, so that when the telescopic rod 1222 is extended or retracted by one unit length, it helps to shorten the arc length of the rotation of the end of the telescopic rod 1222, thereby reducing the rotation angle of the end of the telescopic rod 1222 with the first ear 1215 as the center, so as to achieve the effect of the flip driver 122 driving the flip member 121 to rotate a smaller angle.

[0099] For further information, see Figure 5 and Figure 7The top of the flipping member 121 is provided with a fixing member 1211, which is located at one side of the first ear 1215 in the third direction Z. The fixing member 1211 is provided with a first working part 1212 and a second working part 1213 at intervals along the second direction Y. The cylinder 1221 is fixedly connected to the bottom of the slider 132. The end of the telescopic rod 1222 is located between the fixing member 1211 and the first ear 1215. The end of the telescopic rod 1222 is connected with a flipping working part 12221. In the third direction Z, the flipping working part 12221 extends from the telescopic rod 1222 to between the first working part 1212 and the second working part 1213. The cylinder 1221 drives the telescopic rod 1222 to move up and down, so that the flipping working part 12221 lifts the first working part 1212 or presses down the second working part 1213, thereby achieving the effect that the flipping driver 122 drives the fixing member 1211 to drive the flipping member 121 to rotate. Furthermore, the fixing member 1211 is disposed away from the first ear 1215, which helps to increase the distance between the fixing member 1211 and the first ear 1215, so that when the telescopic rod 1222 is extended or retracted by one unit length, the arc length of the rotation of the fixing member 1211 is shortened, thereby reducing the rotation angle of the fixing member 1211 with the first ear 1215 as the center, thereby achieving the effect of the flip driver 122 driving the flip member 121 to rotate a smaller angle.

[0100] At the same time, relative to Figure 6 The middle cylinder 1221 and the telescopic rod 1222 are respectively inclined from the upper left to the lower right, using Figure 7 The middle cylinder body 1221 is fixedly connected to the bottom of the slider 132, and the flipping working part 12221 is provided, which helps to avoid air on both sides of the first ear 1215 and the second ear 1321, thereby reducing the risk of the cylinder body 1221 and the telescopic rod 1222 colliding with the outside.

[0101] In addition, the provision of the first ear 1215 and the second ear 1321 increases the distance between the slider 132 and the flip member 121 , so that the cylinder body 1221 and the telescopic rod 1222 are disposed between the slider 132 and the flip member 121 .

[0102] In some embodiments, the first working portion 1212 and the second working portion 1213 are spaced apart by a specified distance, thereby helping to reduce the risk of the first working portion 1212 and the second working portion 1213 jointly clamping the flipping working portion 12221 when the fixing member 1211 and the flipping member 121 rotate relative to the slider 132 .

[0103] In some embodiments, when the fixing member 1211 rotates relative to the slider 132, the relative position of the fixing member 1211 and the flip working portion 12221 will change. The first working portion 1212 and the second working portion 1213 are rod-shaped components. Figure 7The first working part 1212 and the second working part 1213 are rotatably provided with rollers 1214. When the flip driver 122 is working, the rollers 1214 roll in contact with the flip working part 12221, thereby helping to reduce the friction resistance between the flip working part 12221 and the first working part 1212 and the second working part 1213.

[0104] In some embodiments, see Figure 4 and Figure 5 Each clamping assembly 11 includes two clamping cylinders 111 and two clamping jaws 112. In the first direction X, the two clamping cylinders 111 are relatively arranged on both sides of the flip member 121, and the two clamping jaws 112 are located below the flip member 121. One clamping jaw 112 is connected to one clamping cylinder 111. The two clamping cylinders 111 drive the two clamping jaws 112 to move closer or farther away, thereby achieving the effect of the two clamping jaws 112 clamping the carrier 20 or releasing the carrier 20.

[0105] In some embodiments, see Figure 5 Each clamping jaw 112 is provided with a through slot 1121 facing the corresponding other clamping jaw 112. When the clamping jaw 112 clamps the supporting member 20, the boat rod 21 on the supporting member 20 is accommodated by the through slot 1121 to reduce the risk of interference between the clamping jaw 112 and the boat rod 21.

[0106] In some embodiments, see Figure 5 The through slot 1121 extends along the second direction Y so that the two clamping jaws 112 can approach each other while the clamping assembly 11 moves downward toward the carrier 20 , which helps to increase the speed at which the clamping mechanism 10 clamps the carrier 20 .

[0107] In some embodiments, see Figure 5 The through slot 1121 is connected to the bottom surface of the clamping jaw 112. A support rod 1122 is also provided on the clamping jaw 112. The support rod 1122 is located at the lower end of the through slot 1121. When the clamping jaw 112 clamps the carrier 20, the support rod 1122 supports the boat rod 21 of the carrier 20, which helps to improve the stability of the clamping assembly 11 clamping the carrier 20.

[0108] In some embodiments, see Figure 5 The support rod 1122 is located on the side of the clamping jaw 112 facing the other clamping jaw 112 , so that the support rod 1122 contacts the end surface of the carrier 20 .

[0109] In other embodiments, the through slot 1121 is an oblong hole slot (not shown). When the clamping jaw 112 clamps the carrier 20 , the bottom wall of the through slot 1121 supports the boat rod 21 of the carrier 20 , which helps to improve the stability of the clamping assembly 11 in clamping the carrier 20 .

[0110] In some embodiments, see Figures 3 to 5 The clamping mechanism 10 further includes a first detection component 15, which includes a first photoelectric sensor 151 and a first baffle 152. The first photoelectric sensor 151 is disposed on the top of the flip member 121, and the first baffle 152 is disposed on the second support ear 1321. A portion of the first baffle 152 extends into the sensing area of ​​the first photoelectric sensor 151. When the flip driver 122 drives the flip member 121 to drive the clamping assembly 11 to rotate, the flip member 121 simultaneously drives the first photoelectric sensor 151 to rotate relative to the first baffle 152, so as to adjust the position of the portion of the first baffle 152 located in the sensing area of ​​the first photoelectric sensor 151, thereby achieving the effect of measuring the rotation angle of the flip member 121. When the first photoelectric sensor 151 senses that the first baffle 152 rotates a specified angle, the first photoelectric sensor 151 sends a feedback signal to the flip driver 122, so as to stop the flip driver 122 from working, thereby achieving the effect of flipping and limiting the flip member 121 and the clamping assembly 11.

[0111] In some embodiments, see Figure 4 The clamping mechanism 10 further includes a second detection assembly 16, which includes a second baffle 161 and at least two second photoelectric sensors 162. The at least two second photoelectric sensors 162 are spaced apart at the top of the slide rail 131. The second baffle 161 is disposed on the mounting frame 142. A portion of the second baffle 161 extends from the mounting frame 142 toward the slide rail 131 and can be located within the sensing area of ​​the second photoelectric sensors 162. When the rotary driver 141 drives the slide rail 131 to rotate relative to the mounting frame 142, the slide rail 131 synchronously drives all the second photoelectric sensors 162 to rotate relative to the second baffle 161. When the second baffle 161 moves from the sensing area of ​​one second photoelectric sensor 162 to the sensing area of ​​another second photoelectric sensor 162, the other second photoelectric sensor 162 sends a feedback signal to the rotary driver 141 to stop the rotary driver 141 from working, thereby achieving the effect of rotationally limiting the slide rail 131.

[0112] In some embodiments, since both sides of the carrier 20 are hollowed out, part of the sheet material 40 easily extends out of the outside of the carrier 20. Figure 4 and Figure 5The clamping mechanism 10 further includes a third detection component 17, which includes two first photoelectric sensors 171 and two second photoelectric sensors 172. The two first photoelectric sensors 171 are respectively arranged on both sides of one clamping jaw 112 in the first direction X, and the two second photoelectric sensors 172 are respectively arranged on both sides of another clamping jaw 112 in the first direction X. One first photoelectric sensor 171 corresponds to one second photoelectric sensor 172. When part of the sheet material 40 extends out of the outer side of the carrier 20, the sheet material 40 blocks the sensing area between the first photoelectric sensor 151 and the second photoelectric sensor 162, and the first photoelectric sensor 151 and the second photoelectric sensor 162 send out an alarm signal, thereby improving the accuracy of the clamping mechanism 10 in feeding the carrier 20, so as to reduce the risk of the sheet material 40 extending outward from one carrier 20 contacting the sheet material 40 on the adjacent carrier 20.

[0113] In some embodiments, the first photoelectric sensor 171 and the second photoelectric sensor 172 are opposing optical fibers.

[0114] In some embodiments, the clamping mechanism 10 also includes a fourth detection component (not shown), the fourth detection component includes a third baffle (not shown) and a third photoelectric sensor (not shown), multiple photoelectric sensors are arranged on the slide rail 131, the third baffle is arranged on the slider 132, and part of the third baffle extends into the sensing area of ​​the third photoelectric sensor. When the translation driver 133 drives the corresponding slider 132 to move relative to the slide rail 131, the slider 132 synchronously drives the third baffle 1332 to move into the sensing area of ​​the third photoelectric sensor, and the third photoelectric sensor sends a feedback signal to the translation driver 133, and the translation driver 133 stops working, thereby achieving the effect of limiting the movement of the slider 132.

As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
