Description

Technical Field

[0001] This utility model relates to the field of auxiliary calibration technology, specifically a robotic arm position auxiliary calibration tool for the photovoltaic industry. Background Technology

[0002] In the photovoltaic industry, robotic arms are widely used in the automated transfer of silicon wafer baskets during the production of solar cells. As a key tool for carrying silicon wafers, the positioning accuracy of the basket directly affects the stability of the production process and the safety of the silicon wafers. When the robotic arm performs basket picking and placing, it needs to accurately align with specific positioning points at the top and bottom of the basket to ensure a smooth and reliable transfer process.

[0003] In actual calibration, due to the limitations of the flower basket structure and the operating space of the robotic arm, it is difficult for calibration personnel to observe the top and bottom positions of the flower basket at the same time. The existing calibration methods mainly include the following: manual segmented visual calibration method, in which the operator needs to repeatedly move his body position to observe and adjust the relative position of the robotic arm and the top of the flower basket from different angles; multi-person collaborative calibration method, which requires multiple people to observe together and direct the operator; and simple tool-assisted method, in which the operator uses a common small handheld mirror to observe the reflected image of the top or bottom individually.

[0004] In existing methods for calibrating flower baskets, the robotic arm needs to be aligned and fixed simultaneously with the relative positions of the top and bottom of the basket. However, the calibrator cannot see the top and bottom at the same time, which causes inconvenience in calibration and easily leads to misalignment and calibration failure.

[0005] Therefore, a robotic arm position-assisted calibration tool for the photovoltaic industry is proposed to address the above problems. Utility Model Content

Support rods are bolted to the four corners between the two fixing plates. A pair of reflectors are arranged between the two fixing plates. The two reflectors are arranged at a 90° angle, and the reflective surfaces of the two reflectors correspond to the circular holes of the two fixing plates respectively.

[0008] Preferably, a fixing ring is fixedly connected to the side of the fixing plate near the reflector; the inner diameter of the fixing ring is the same as the diameter of the circular hole in the middle of the fixing plate; a rotating ring is rotatably mounted on the outer ring of the fixing ring; and the reflector is hinged to the bottom of the rotating ring.

[0011] Preferably, the limiting block has an arc-shaped structure, and the arc-shaped concave surface of the limiting block matches the inner ring of the outer ring groove; the arc-shaped concave surface of the limiting block is provided with anti-slip texture.

[0012] Preferably, a pair of connectors for fixing the two reflectors are provided between the sides of the two reflectors that are close to each other; the connectors include a fixing plate; a screw is fixedly connected to the middle of the side of the fixing plate that is far apart on both sides; a rotating disk is slidably mounted on the outer ring of the screw; an extension post is fixedly connected to the outer ring of both the fixing plate and the outer ring of the rotating disk; an adhesive plate is fixedly connected to the end of each of the two extension posts that is far away from the screw; the adhesive plate is bonded to the back surface of the reflector; a locking nut that presses against the rotating disk is threaded onto the outer ring of the screw.

[0013] Preferably, the diameter of the rotating disk is smaller than the diameter of the fixed disk; the outer circumference of the fixed disk near the rotating disk is provided with scale lines; the zero line of the scale lines is aligned with the center line of the extended column of the outer circumference of the fixed disk.

[0014] Preferably, a diamond-shaped through groove is provided in the middle of the extension column of the rotating disk; the diamond-shaped through groove corresponds to the scale line.

[0016] Preferably, a square frame is bolted to the bottom surface of the rotating ring; the reflector is hinged to one side of the square frame; and a sponge pad is fixed to the side of the square frame near the reflector.

[0017] The advantages of this utility model are: 1. The present invention relates to a robotic arm positioning auxiliary calibration tool for the photovoltaic industry, comprising a fixed plate, a support rod, and a pair of reflectors. The calibration tool is placed in the center of the basket, with the circular hole of the fixed plate aligned with the through hole of the basket's end plate. Since the angle between the reflective surface of the reflector and the fixed plate is 45°, the operator can simultaneously observe the through hole of the basket's end plate through the reflection of the two reflectors during calibration. This allows the operator to control the robotic arm to simultaneously align and fix with the through holes of both end plates of the basket, improving the accuracy of the robotic arm in gripping the basket and increasing the efficiency of basket handling.

[0018] 2. The present invention provides a robotic arm-based point-of-care calibration tool for the photovoltaic industry. It comprises a fixed ring and a rotating ring. After the calibration tool is placed and fixed inside the center of a basket, the through-holes on the basket's end plate are simultaneously observed using the reflections of two mirrors. Due to the different positions of the operators, observation requires the operators to move to the side facing the reflective surfaces of the two mirrors. However, in actual operation, obstructions from the robotic arm and other equipment make it difficult for the operators to move to the observation position on the basket. At this point, the operator manipulates the two mirrors to rotate, causing the rotating ring to rotate around the fixed ring, controlling and adjusting the orientation of the two mirrors so that the reflective surfaces of the two mirrors face the operator, thus facilitating the operator's calibration work.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1 to 3 As shown, a robotic arm positioning auxiliary calibration tool for the photovoltaic industry is disclosed. The calibration tool can be placed inside a flower basket. The calibration tool includes a pair of fixing plates 1. A circular hole is opened in the middle of the fixing plate 1. Support rods 2 are bolted to the four corners between the two fixing plates 1. A pair of reflectors 3 are arranged between the two fixing plates 1. The two reflectors 3 are arranged at a 90° angle, and the reflective surfaces of the two reflectors 3 correspond to the circular holes of the two fixing plates 1 respectively. Specifically, the basket is a key tooling for carrying silicon wafers. The basket includes a pair of end plates, and the middle of the end plates has through holes for the robotic arm to grip and fix them. Multiple uprights are fixed to the three sides between the two end plates. A vertical rack for fixing and separating the silicon wafers is fixed to the side of the uprights near the center of the basket. The fixing plate 1 has a square structure and can be slidably inserted into the vertical rack of the flower basket, so that the calibration tool is fixed inside the flower basket. At this time, the round hole of the fixing plate 1 is aligned with the through hole in the middle of the end plate of the flower basket, and the diameter of the round hole of the fixing plate 1 is larger than the through hole of the end plate. The included angle between the two reflectors 3 is 90°, and the reflective surfaces of the two reflectors 3 are opposite to each other, so that the reflective surfaces of the two reflectors 3 correspond to the round holes of the two fixing plates 1 respectively. In use, the calibration tool is placed in the center of the flower basket, so that both fixing plates 1 slide into the grooves of the vertical rack, thus fixing the calibration tool. At this time, the round hole of the fixing plate 1 is aligned with the through hole of the flower basket end plate. Since the angle between the reflective surface of the reflector 3 and the fixing plate 1 is 45°, the operator can simultaneously observe the through hole of the flower basket end plate through the reflection of the two reflectors 3 when performing calibration. This allows the operator to control the robot arm to simultaneously align and fix with the through holes of the two end plates of the flower basket, improving the accuracy of the robot arm in gripping the flower basket and increasing the efficiency of grasping the flower basket.

[0024] Furthermore, such as Figures 2 to 4 As shown, a fixing ring 4 is fixedly connected to the side of the fixing plate 1 near the reflector 3; the inner diameter of the fixing ring 4 is the same as the diameter of the circular hole in the middle of the fixing plate 1; a rotating ring 5 is rotatably installed on the outer ring of the fixing ring 4; the reflector 3 is hinged to the bottom of the rotating ring 5. Specifically, the inner ring of the fixing ring 4 has the same diameter as the circular hole of the fixing plate 1 and is concentrically set; the two reflectors 3 are connected to the bottom side of the rotating ring 5 on opposite sides, so that the rotating ring 5 can drive the reflectors 3 to rotate. In use, after the calibration tool is placed and fixed in the middle of the inside of the flower basket, the through hole of the flower basket end plate is observed simultaneously using the reflection of the two reflectors 3. Due to the different positions of the operators, the operators need to move to the side facing the reflective surface of the two reflectors 3 when observing. However, in actual operation, the obstruction of the robotic arm and other equipment makes it difficult for the operators to move to the observation position of the flower basket. At this time, the operator manipulates the two reflectors 3 to rotate, causing the rotating ring 5 to rotate around the fixed ring 4, controlling and adjusting the orientation of the two reflectors 3 so that the reflective surface of the two reflectors 3 faces the operator, thus facilitating the operator's calibration work.

[0025] In some embodiments, such as Figures 4 to 7 As shown, the top of the outer ring of the fixed ring 4 is provided with a plurality of mounting holes 6; an elastic buckle 7 is fixedly connected inside the mounting holes 6; the top of the inner ring of the rotating ring 5 is provided with a plurality of hemispherical grooves 8; the elastic buckle 7 can engage with the hemispherical grooves 8. Specifically, multiple mounting holes 6 are evenly distributed around the outer ring of the fixed ring 4, and multiple hemispherical grooves 8 are evenly distributed around the inner ring of the rotating ring 5, with the mounting holes 6 corresponding to the hemispherical grooves 8. The elastic buckle 7 includes a cylindrical outer cylinder with an opening at one end and a flange on the inner ring of the opening. A hemispherical buckle is slidably installed inside the outer cylinder. The hemispherical buckle can slide out of the opening of the outer cylinder and be engaged in the hemispherical groove 8. The outer ring of the hemispherical buckle has a raised ring, which can be blocked by the flange of the opening of the cylinder. A spring is installed inside the outer cylinder, which can push the hemispherical buckle to slide toward the opening of the outer cylinder. The elastic buckle 7 is inserted into the mounting hole 6 of the outer ring of the fixing ring 4, so that the hemispherical buckle can protrude from the outer wall of the fixing ring 4. In use, the operator manipulates the two reflectors 3 to rotate, causing the rotating ring 5 to rotate around the fixed ring 4. As the rotating ring 5 rotates, it causes the hemispherical groove 8 to misalign with the mounting hole 6 on the outer ring of the fixed ring 4. This causes the inner wall of the rotating ring 5 to press against the hemispherical protrusion of the elastic buckle 7, causing the hemispherical protrusion to retract into the outer cylinder, thus compressing and storing spring force. When the reflector 3 rotates to a certain angle, the hemispherical groove 8 on the inner ring of the rotating ring 5 aligns with the mounting hole 6 on the outer ring of the fixed ring 4. At the same time, the spring inside the elastic buckle 7 resets, pushing the hemispherical protrusion to slide out from the inside of the outer cylinder, allowing the hemispherical protrusion to engage with the hemispherical groove 8 on the inner ring of the rotating ring 5. This allows the reflector 3 to be adjusted and fixed at multiple angles, making it easier for the operator to calibrate it from different positions on the flower basket.

[0026] In some embodiments, such as Figures 4 to 8 As shown, the outer ring 4 has an outer ring groove 9 in the middle of its outer ring; the inner ring 5 has an inner ring groove 10 in the middle of its inner ring; the inner ring groove 10 corresponds to the outer ring groove 9 and is fitted around the outer ring of the outer ring groove 9; a plurality of limiting blocks 11 are arranged around the inside of the inner ring groove 10; the limiting blocks 11 can extend into the outer ring groove 9; Specifically, the outer ring of the inner ring groove 10 is provided with multiple sliding holes, and the sliding holes penetrate the outer wall of the rotating ring 5. A hexagonal groove is provided at one end of the sliding hole located on the outer wall of the rotating ring 5. A hexagonal nut is inserted into the hexagonal groove. A lead screw 12 is installed in the internal thread of the hexagonal nut. The end of the lead screw 12 near the limit block 11 is rotatably connected to the limit block 11. During installation, the rotating ring 5 is slidably fitted onto the outer ring of the fixed ring 4, aligning the inner ring groove 10 of the inner ring of the rotating ring 5 with the outer ring groove 9 of the outer ring of the fixed ring 4. At this time, the operator uses a wrench to rotate the lead screw 12, which engages with the hexagonal nut, causing the lead screw 12 to move into the inner ring groove 10, pushing the limiting block 11 from the inner ring groove 10 into the outer ring groove 9, without the limiting block 11 contacting the inner wall of the outer ring groove 9. By fixing the limiting block 11 between the inner ring groove 10 and the outer ring groove 9, the rotating ring 5 is positioned on the outer ring of the fixed ring 4, allowing the rotating ring 5 to rotate on the outer ring of the fixed ring 4 without detaching. When the reflector 3 is rotated to a certain angle and needs to be locked, the operator uses a wrench to rotate the lead screw 12. The lead screw 12 pushes the limit block 11 to press against the inner wall of the outer ring groove 9, locking the rotating ring 5 and the fixed ring 4, thereby fixing the reflector 3.

[0027] Furthermore, such as Figure 5 and Figure 8 As shown, the limiting block 11 has an arc-shaped structure, and the arc-shaped concave surface of the limiting block 11 matches the inner ring of the outer ring groove 9; the arc-shaped concave surface of the limiting block 11 is provided with anti-slip texture. Specifically, by setting the limiting block 11 into an arc-shaped structure that matches the inner ring of the outer ring groove 9, and by setting anti-slip texture on the concave surface of the limiting block 11, the contact area and frictional resistance between the limiting block 11 and the inner wall of the outer ring groove 9 are increased, thereby improving the locking strength between the rotating ring 5 and the fixed ring 4.

[0028] In some embodiments, such as Figures 9 to 10 As shown, a pair of connectors for fixing the two reflectors 3 are provided between their adjacent sides; the connectors include a fixing plate 13; a screw 14 is fixedly connected to the middle of the opposite side of the fixing plate 13; a rotating disk 15 is slidably mounted on the outer ring of the screw 14; an extension post is fixedly connected to the outer ring of both the fixing plate 13 and the rotating disk 15; an adhesive plate 16 is fixedly connected to the end of each of the two extension posts away from the screw 14; the adhesive plate 16 is bonded to the back surface of the reflector 3; a locking nut that presses against the rotating disk 15 is threaded onto the outer ring of the screw 14; Specifically, the connector is located on the side of the two reflectors 3 that are close to each other and on the back side of the reflector 3; both the fixing plate 13 and the rotating plate 15 are circular structures; the adhesive plate 16 is a long strip plate structure, and a vacuum suction cup is provided on the side of the adhesive plate 16 that is close to the reflector 3, so as to use the negative pressure of the vacuum suction cup to adhere and fix it to the back side of the reflector 3. In use, the rotating disk 15 is fitted onto the outer ring of the screw 14 of the fixed disk 13, and the rotating disk 15 is rotated to adjust the included angle between the two adhesive plates 16 to 90°. Then, the locking nut on the screw 14 is rotated to press the rotating disk 15, so that the rotating disk 15 is locked and fixed to the fixed disk 13. Then, the vacuum suction cups on the two adhesive plates 16 are respectively attracted and fixed to the back surface of the two reflectors 3, thereby connecting and fixing the two reflectors 3 and ensuring that the two reflectors 3 maintain a 90° included angle. When the calibration tool needs to be stored or transported, the unfolded calibration tool requires a large amount of space. At this time, the vacuum suction cup on the adhesive plate 16 is separated from the back surface of the reflector 3, so that the connection between the two reflectors 3 is broken. Then, the reflector 3 is flipped so that it is close to the fixing ring 4 and the rotating ring 5. At the same time, it can be fixed with tape, etc. After that, the support rod 2 between the two fixing plates 1 is removed. Then, the two parts of the fixing plates 1 and the reflector 3 are overlapped, so that the calibration tool is effectively folded and contracted, reducing the overall volume, thus facilitating storage and transportation.

[0029] Furthermore, such as Figures 9 to 10 As shown, the diameter of the rotating disk 15 is smaller than the diameter of the fixed disk 13; a scale line 17 is arranged around the outer ring of the side of the fixed disk 13 closest to the rotating disk 15; the zero line of the scale line 17 is aligned with the center line of the extension column of the outer ring of the fixed disk 13; a diamond-shaped through groove 18 is opened in the middle of the extension column of the rotating disk 15; the diamond-shaped through groove 18 corresponds to the scale line 17. Specifically, when rotating the rotating disk 15 to adjust the angle between the two adhesive plates 16, the set scale line 17, with its zero-degree line aligned with the center line of the extension column of the fixed disk 13, facilitates the adjustment of the angle between the two adhesive plates 16. At the same time, the diamond-shaped through groove 18, with its two tips aligned with the center line of the extension column of the rotating disk 15, ensures that the scale of the scale line 17 is accurately aligned with the center line of the extension column of the rotating disk 15, thereby facilitating accurate and intuitive observation of the adjusted angle.

[0030] Furthermore, such as Figures 9 to 10 As shown, a connecting rod 19 is bolted between the middle parts of the two fixed disks 13; Specifically, flanges are fixed to both ends of the connecting rod 19, and the flanges are fixed to the fixed plate 13 by multiple screws; the connecting rod 19 fixes the two fixed plates 13 together, thereby improving the connection strength between the connecting parts on both sides, and thus improving the connection stability between the two reflectors 3.

[0031] Furthermore, such as Figures 2 to 9 As shown, a square frame 20 is bolted to the bottom surface of the rotating ring 5; the reflector 3 is hinged to one side of the square frame 20; a sponge pad is fixed to the side of the square frame 20 near the reflector 3. Specifically, the four corners of the square frame 20 are bolted to the bottom of the rotating ring 5 with screws. The square frame 20 facilitates the hinge of the reflector 3 to the bottom of the rotating ring 5. At the same time, since the square frame 20 is equipped with a sponge pad, when the calibration tool is folded and the reflector 3 is close to the fixed ring 4 and the rotating ring 5, the reflective surface of the reflector 3 contacts the sponge pad on the square frame 20, thereby avoiding damage to the reflective surface of the reflector 3 and improving the safety of the reflector 3.

[0032] Working principle: The two fixing plates 1 are supported and fixed using the support rod 2. The rotating disk 15 is placed on the outer ring of the screw 14 of the fixing disk 13, and the rotating disk 15 is rotated to adjust the included angle between the two adhesive plates 16 to 90°. Then, the locking nut on the screw 14 is rotated to press the rotating disk 15, so that the rotating disk 15 is locked and fixed to the fixing disk 13. Then, the vacuum suction cups on the two adhesive plates 16 are respectively attracted and fixed to the backlight surface of the two reflectors 3. The calibration tool is placed in the center of the flower basket, so that both fixing plates 1 slide into the grooves of the vertical rack, thus fixing the calibration tool. At this time, the round hole of the fixing plate 1 is aligned with the through hole of the flower basket end plate. Due to the different positions of the operators, when observing, the operators need to move to the side facing the reflective surface of the two reflectors 3. However, in actual operation, the obstruction of the robotic arm and other equipment makes it difficult for the operators to move to the observation position of the flower basket. At this time, the operators manipulate the two reflectors 3 to rotate, causing the rotating ring 5 to rotate around the fixing ring 4, controlling and adjusting the orientation of the two reflectors 3 so that the reflective surface of the two reflectors 3 faces the operators. Since the angle between the reflective surface of the reflector 3 and the fixed plate 1 is 45°, the operator can simultaneously observe the through holes of the flower basket end plates through the reflection of the two reflectors 3 when calibrating. This allows the operator to control the robot arm to align and fix itself with the through holes of the two end plates of the flower basket at the same time, improving the accuracy of the robot arm in holding the flower basket and increasing the efficiency of grasping the flower basket.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
