Description

Technical Field

[0001] This utility model relates to the technical field of silicon rod testing equipment, and in particular to a rotatable silicon half rod clamping device and a silicon half rod size testing device. Background Technology

[0002] Prior to 2025, finished silicon rods in the photovoltaic industry were mainly produced as whole rods, with common side lengths of 182mm x 182mm, 182mm x 210mm, and 210mm x 210mm, and a square cross-section. However, with advancements in silicon rod processing technology, the market now primarily offers products with cross-sectional dimensions of 182mm x 91mm, 182mm x 105mm, and 210mm x 105mm. These are produced by splitting the whole rod in half along its width, commonly known as silicon half rods.

[0003] After the finished silicon half rod is manufactured, the silicon half rod needs to be inspected for size. The size inspection mainly includes the distance between opposite sides, the distance between opposite corners, the arc length and projection, as well as the angle between each side. The inspection accuracy is usually within ±0.02mm.

[0004] Currently, the photovoltaic industry relies solely on manual methods for inspecting silicon half-rods; no automated equipment exists for this purpose. During inspection, workers use specialized calipers and angle measuring devices to repeatedly flip the workpiece to measure all dimensions. This method is susceptible to human error, resulting in low accuracy, low efficiency, and long inspection times. Furthermore, manually flipping the workpiece increases the risk of personal injury. Additionally, visually identifying surface quality issues such as chipped edges can easily lead to omissions or misidentifications.

[0005] Currently, there are automatic devices for detecting the dimensions of whole ingots. However, if we want to modify these devices to detect the dimensions of silicon half ingots, the detection cycle time for silicon half ingots is only 44 seconds, half the 90 seconds required for detecting the dimensions of finished whole ingots, to meet the overall cycle time requirements for converting from whole ingots to silicon half ingots (the ratio of whole ingots to silicon half ingots is 1:2). This is insufficient for the original finished whole ingot detection device. Therefore, this invention proposes a rotatable silicon half ingot clamping device and a silicon half ingot dimension detection device to meet the production cycle time requirements for silicon half ingots.

[0006] In addition, current whole bar size inspection equipment uses grippers mounted on a three-axis linear motion module, which drives the gripper's movement. This requires the arrangement of guide rails on each axis on the production line, resulting in a relatively large equipment size. Utility Model Content

[0007] This invention primarily addresses the technical problems of current silicon half-rod inspection, which relies on manual measurement using professional calipers and arc-angle measuring equipment.

Detailed Implementation

[0039] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0040] Example 1

[0041] like Figure 1-2 As shown in the figure, the rotatable silicon half rod clamping device provided in this embodiment of the present invention includes: an electric rotary table 31, a rotating frame 32, an electric lifting module 33, a gripper mechanism 34, and a base 35.

[0042] An electric rotary table 31 is provided on the base 35; a rotating frame 32 is provided on the electric rotary table 31; electric lifting modules 33 are provided at both ends of the rotating frame 32; and a gripper mechanism 34 is provided at the output end of the electric lifting module 33.

[0043] The electric rotary table 31 can realize the rotation of the rotating frame 32, the gripper mechanism 34 and the workpiece 1 in a 360° range, and the electric lifting module 33 can move the gripper mechanism 34 up and down to realize the raising and lowering of the workpiece 1.

[0044] like Figure 3-6 As shown, the gripper mechanism 34 includes: a mounting plate 3401, a rack 3402, a linear guide rail 3403, a gear 3404, a push rod cylinder 3405, a gripper frame 3407, and a vacuum suction cup 3410. The mounting plate 3401 serves as the main base plate of the gripper mechanism 34. The mounting plate 3401 is connected to the output end of the electric lifting module 33 via a connecting flange plate 3411. The electric lifting module 33 drives the mounting plate 3401 and its components to rise and fall, thus realizing the vertical movement of the entire gripper mechanism 34. Cylindrical guide rods 3406 are respectively provided on both sides above the mounting plate 3401; the cylindrical guide rods 3406 pass through the rotating frame 32 and guide the movement during vertical movement.

[0045] The mounting plate 3401 has a strip groove 3413; linear guide rails 3403 are provided on the bottom surface of the mounting plate 3401 and on both sides of the strip groove 3413; gripper frames 3407 are respectively provided at both ends of the bottom of the mounting plate 3401; multiple rollers 3408 are mounted on the side of the gripper frame 3407. A slider is provided on the gripper frame 3407; the slider is slidably connected to the corresponding linear guide rail 3403.

[0046] A gear 3404 is disposed above the mounting plate 3401; specifically, the gear 3404 is rotatably mounted on a pad 3414, which is disposed on the mounting plate 3401 and positions the gear 3404 above the slot 3413. Racks 3402 mesh with each other on both sides of the gear 3404; each rack 3402 is connected to a gripper frame 3407 via a connector 3412.

[0047] The mounting plate 3401 has a push rod cylinder 3405 at one end of the strip groove 3413; the output end (push rod head) of the push rod cylinder 3405 is connected to a rack 3402; when the push rod cylinder 3405 extends or retracts, the rack 3402 connected to the push rod cylinder 3405 will be driven to move linearly, and the gear 3404 will be driven to rotate by the rack 3402. The rack 3402 on the other side will also be driven to move by the gear 3404. The two racks 3402 move in opposite directions. Therefore, the gripper frames 3407 on both sides will move in opposite directions with their respective connected racks 3402, and finally the gripper can be opened and closed.

[0048] The bottom surface of the mounting plate 3401 is provided with a plurality of vacuum suction cups 3410. A vacuum generator 3409 is provided on the mounting plate 3401, and the vacuum generator 3409 is connected to the vacuum suction cups 3410.

[0049] When the gripper frame 3407 moves down to the gripping position, the vacuum suction cup 3410 contacts the upper surface of the workpiece 1. The vacuum generator 3409 is activated, and the vacuum suction cup 3410 sucks up the workpiece 1. Then, the push rod cylinder 3405 extends to push the rack 3402, and the two racks 3402 move relative to each other. The gripper frames on both sides 3407 clamp the workpiece 1 in the closing direction, and the rollers 3408 press firmly against the side of the workpiece 1. The workpiece 1 is finally completely sucked up and clamped on the gripper mechanism 34, and there is no risk of it falling off during the subsequent rotation and movement.

[0050] The working principle of the rotatable silicon half-rod clamping device provided by this utility model is as follows: There are two gripper mechanisms 34. One gripper mechanism 34 grips the workpiece 1 to be inspected, and the other gripper mechanism 34 grips the workpiece 1 after inspection. After gripping, the electric lifting module 33 drives the gripper mechanism 34 and the workpiece on it to rotate 180°, so that the positions of the workpiece 1 to be inspected and the workpiece 1 after inspection are switched. The loading of the workpiece 1 to be inspected and the unloading of the workpiece 1 after inspection can be completed in one action, which improves the workpiece conveying efficiency. The electric lifting module 33 then drives the gripper mechanism 34 and the workpiece on it to descend for unloading. The silicon half-rod clamping device of this utility model can clamp and rotate the workpiece, which is convenient for gripping and unloading the workpiece 1. By adopting the form of electric rotary table 31, rotating frame 32, electric lifting module 33 and gripper mechanism 34, the size of the device is greatly reduced. The gripper mechanism 34 can lift, rotate and grip the workpiece 1, improve the workpiece clamping and conveying efficiency, and can adapt to various types of workpieces and various production scenarios.

[0051] Example 2

[0052] like Figure 7-9As shown, this utility model provides a silicon half rod size detection device, including: roller conveyor 2, detection device 4, bottom frame 5, and silicon half rod clamping device 3 provided in any embodiment of this utility model.

[0053] The silicon half-bar clamping device 3 has a roller conveyor 2 on one side and a detection device 4 on the other side. The silicon half-bar clamping device 3, roller conveyor 2, and detection device 4 are mounted on a base frame 5. The base frame 5 is welded from square steel tubing. The roller conveyor 2 is a common material transport mechanism and will not be described in detail. The structure and principle of the detection device 4 are adapted from existing finished bar size detection devices and will not be described in detail.

[0054] like Figure 9 As shown, the silicon half-rod dimensional inspection equipment of this utility model has two stations: a workpiece to be inspected and a detection station. Workpiece 1 is fed onto the roller conveyor 2 and stops at the workpiece to be inspected. The silicon half-rod clamping device 3 can switch the position of workpiece 1 between the workpiece to be inspected and the detection station. It can also simultaneously grip and rotate 180° when there is material at both stations, completing the delivery of the material to be inspected and the unloading of the inspected material. The detection station mainly uses the detection device 4 to perform dimensional inspection on the placed workpiece 1.

[0055] This utility model provides a working process for a silicon half-rod size detection device:

[0056] Step 1: Workpiece 1 is transferred from the front-end process to this inspection equipment and enters the inspection position on the roller conveyor line 2 to wait to be picked up.

[0057] Step 2: After the detection device 4 completes the detection of the previous rod and returns to its original position, the silicon half rod clamping device 3 rotates and moves the gripper mechanisms 34 at both ends to the designated position. Then, the electric lifting modules 33 at both ends move the gripper mechanisms 34 down to the gripping position.

[0058] Step 3: The vacuum suction cup 3410 on the gripper mechanism 34 picks up the workpiece 1, and the push rod cylinder 3405 actuates to clamp the workpiece 1 with the gripper frames 3407 on both sides. One gripper mechanism 34 grips the workpiece 1 to be inspected, and the other gripper mechanism 34 grips the workpiece 1 after inspection.

[0059] Step 4: The electric lifting modules 33 at both ends lift the gripper mechanism 34 and the workpiece 1 upward to the designated position. Then, the electric rotary table 31 rotates the rotating frame 32, along with the gripper mechanism 34 and the workpiece 1, by 180°, so that the position of the workpiece 1 to be inspected is switched with that of the inspected workpiece 1.

[0060] Step 5, Unloading: The electric lifting module 33 moves the gripper mechanism 34 downward to the gripping position, the vacuum suction cup 3410 returns to normal pressure and releases the workpiece 1, the push rod cylinder 3405 retracts and opens the two side gripper frames 3407, so that the workpiece 1 to be inspected is placed on the inspection position so that the inspection device 4 can perform inspection; the inspected workpiece 1 is placed on the inspection position so that the roller conveyor line 2 can transport the inspected workpiece 1 to the downstream process.

[0061] Step 6: After the electric lifting modules 33 at both ends lift the gripper mechanism 34 to the designated position, the electric rotary table 31 rotates the rotating frame 32 and the gripper 34 by 90° to the standby position, waiting for the next gripping operation.

[0062] Step 7: The detection device 4 begins to move and detect the workpiece 1 to be inspected. After the inspection is completed, the detection device 4 returns to its original position. The entire process will repeat steps 1-7.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
