Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cells, in particular to a visually positioned cell positioning platform. Background Art

[0002] In the photovoltaic cell production process, cells need to be transported between various processes. When the cells are transported to the process location via a conveyor belt, the position of the cells needs to be properly adjusted so that the robot can accurately grab them and move them to the next process.

[0003] The position adjustment of the battery cell includes the X direction, Y direction and circumferential direction. During adjustment, camera shooting is used for visual positioning. According to the shooting results, the battery cell is first rotated by a certain angle so that the battery cell is in the positive position relative to the X and Y directions. Then, the movement adjustment in the X and Y directions is performed to achieve accurate positioning of the battery cell.

[0004] However, the existing cell positioning mechanism adjusts the cell in the X, Y and circumferential directions on the positioning platform, which makes the mechanical structure on the positioning platform complex and correspondingly complicates the control logic system. Utility Model Content

[0005] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a battery cell positioning platform for visual positioning which can simplify the structure and ensure positioning accuracy.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a visual positioning battery cell positioning platform, including a fixed base plate, a liftable transfer plate is provided on the fixed base plate, a hollow table plate that can move in the X direction is provided on the transfer plate, a light source base plate is provided above the hollow table plate, a positioning panel is installed on the light source base plate, a backlight source is clamped between the positioning panel and the light source base plate, and a hollow rotating platform that can drive the positioning panel to rotate is installed on the hollow table plate.

[0007] It also has a belt conveyor, and the battery cells are placed on the conveyor belt of the belt conveyor. The belt conveyor transfers the battery cells to the top of the positioning panel, and then the transfer plate rises to allow the positioning panel to support the battery cells; an industrial camera is provided directly above the positioning panel to photograph the position of the battery cells on the positioning panel; a gantry is provided across the belt conveyor, and a suction cup assembly is installed on the gantry that can move in the Y direction to grab the battery cells on the positioning panel.

[0008] The left and right ends of the fixed base plate are respectively installed with lifting cylinders, the piston rods of the lifting cylinders are fixedly connected to the transfer plate, the four corners of the fixed base plate are respectively provided with linear bearings, and the four corners of the bottom surface of the transfer plate are respectively fixed with bearing guide rods that slide with the linear bearings. In this way, when the lifting cylinder pushes the transfer plate to rise and fall, the stability of the transfer plate can be ensured.

[0009] In order to push the hollow table plate to move in the X direction, the transfer plate and the hollow table plate are slidably matched through a slider guide mechanism. A screw nut mechanism is installed on the transfer plate to drive the hollow table plate to move in the X direction. The nut of the screw nut mechanism is fixedly connected to the bottom surface of the hollow table plate.

[0010] Furthermore, in order to adjust the offset of the battery cells on the positioning panel, the hollow rotating platform is installed in the middle of the hollow table plate, and the driving end of the hollow rotating platform is connected to the light source base plate. When the hollow rotating platform drives the light source base plate to rotate, the positioning panel can be driven to rotate synchronously, and the battery cells can be corrected by rotating the positioning panel to a certain angle.

[0011] In order to realize the Y-direction movement of the suction cup assembly, a direct connection module is installed on the upper end face of the gantry, a transplanting plate is fixed on the sliding seat of the direct connection module, a transplanting vertical plate is fixed on the end of the transplanting plate, and a slide cylinder is installed at the bottom of the transplanting vertical plate. The suction cup assembly includes a suction cup bracket plate, and suction cups for sucking battery cells are respectively installed at the four corner ends of the suction cup bracket plate. The suction cup bracket plate is fixedly connected to the bottom of the sliding part of the slide cylinder. The suction cup assembly is pushed to move in the Y-direction through the action of the direct connection module, and the height of the suction cup is adjusted by the slide cylinder, thereby realizing accurate grasping of the battery cell.

[0012] Furthermore, there is a camera holder installed on one side of the end of the belt conveyor, and the industrial camera is installed on the top of the camera holder through a camera holder. In order to improve the shooting brightness of the battery cell, a light source holder is fixed to the bottom of the camera holder, and a ring-shaped light source is installed on the bottom of the light source holder to illuminate the battery cell.

[0013] Since there are unqualified battery cells, a waste box is installed at the bottom of the camera frame facing the output end of the belt conveyor. In this way, the unqualified battery cells are directly sent into the waste box through the belt conveyor to prevent them from being confused with qualified battery cells.

[0014] The beneficial effect of the present invention is that the present invention only requires the battery cells on the positioning panel to be moved and adjusted in the X direction and rotated in the circumferential direction, while the position adjustment of the battery cells in the Y direction can be achieved by moving the suction cup assembly in the Y direction, thereby simplifying the mechanical structure of the positioning platform and correspondingly reducing the complexity of the control logic system.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0020] like Figure 1 、 Figure 2 The shown battery cell positioning platform for visual positioning includes a belt conveyor 8 for transporting battery cells 9. A camera holder 22 is fixed on the ground to the right of the output end of the belt conveyor 8. A camera seat 23 is fixed to the top of the camera holder 22. An industrial camera 10 with a lens facing directly downward is installed on the camera seat 23. A light source bracket 24 is fixed to the bottom of the camera seat 23. A ring light source 25 is installed on the bottom of the light source bracket 24 to provide brightness for shooting of the industrial camera 10.

[0021] A gantry 11 is provided across the belt conveyor 8, and a direct connection module 18 is installed on the upper end face of the gantry 11. A transplanting plate 19 is fixed to the sliding seat of the direct connection module 18. The direct connection module 18 drives the transplanting plate 19 to move in the Y direction. A transplanting vertical plate 20 is fixed at the end of the transplanting plate 19 extending out of the gantry 11, and a slide cylinder 21 is installed at the bottom of the transplanting vertical plate 20. A suction cup assembly 12 for grabbing the battery cell 9 is installed at the bottom of the sliding part of the slide cylinder 21.

[0022] The suction cup assembly 12 includes a suction cup bracket plate 12 - 1 , and suction cups 12 - 2 for sucking the battery sheet 9 are respectively installed at the four corner ends of the suction cup bracket plate 12 - 1 . The suction cup bracket plate 12 - 1 is fixedly connected to the bottom of the sliding part of the slide cylinder 21 .

[0023] A fixed base plate 1, secured to the ground, is located between the gantry 11 and the camera mount 22. A transfer plate 2 is located above the fixed base plate 1. Lifting cylinders 13 are mounted on each end of the fixed base plate 1. The piston rods of the two lifting cylinders 13 are fixedly connected to the left and right ends of the transfer plate 2, respectively. The lifting cylinders 13 operate to move the transfer plate 2 upward and downward. To ensure stable lifting of the transfer plate 2, linear bearings 14 are located at the four corners of the fixed base plate 1. Bearing guide rods 15, which slide in conjunction with the linear bearings 14, are fixed to the four corners of the bottom surface of the transfer plate 2.

[0024] A hollow table plate 3 is provided above the transfer plate 2, and the transfer plate 2 and the hollow table plate 3 are slidably matched through a slider guide rail mechanism 16, wherein the two guide rails of the slider guide rail mechanism 16 are fixed on the transfer plate 2 at a distance, and the two sliders of the slider guide rail mechanism 16 are fixed on the bottom surface of the hollow table plate 3, and respectively slide with the corresponding guide rails.

[0025] A screw-nut mechanism 17 for driving the hollow table plate 3 to move in the X direction is installed on the transfer plate 2 between the two guide rails. The nut of the screw-nut mechanism 17 is fixedly connected to the bottom surface of the hollow table plate 3. The screw of the screw-nut mechanism 17 is rotatably installed on the transfer plate 2. The nut and the screw are coordinated for transmission. A servo motor is installed in reverse on the bottom surface of the transfer plate 2. The output shaft of the servo motor is connected to the left end of the screw through a synchronous belt mechanism, thereby pushing the hollow table plate 3 to move in the X direction.

[0026] A light source base plate 4 is provided above the hollow table plate 3, and a side guard strip is fixed on the front and rear sides of the light source base plate 4 respectively, and a backlight source 6 is clamped between the two side guard strips. The thickness of the backlight source 6 is consistent with the height of the side guard strip, and a positioning panel 5 is fixed on the two side guard strips; a hollow rotating platform 7 is installed in the middle of the hollow table plate 3, and the driving end of the hollow rotating platform 7 is connected to the light source base plate 4. When the hollow rotating platform 7 drives the light source base plate 4 to rotate, it simultaneously drives the positioning panel 5 to rotate, so that the orientation of the battery cell 9 on the positioning panel 5 can be adjusted to an accurate state.

[0027] The upper and lower belts of the belt conveyor 8 are looped back between the positioning panel 5 and the light source base plate 4. After the belt conveyor 8 transfers the battery cell 9 to the top of the positioning panel 5, the belt conveyor 8 stops and the lifting cylinder 13 pushes the transfer plate 2 upward, causing the positioning panel 5 to rise and support the battery cell 9. At this time, the industrial camera 10 is located directly above the positioning panel 5. The industrial camera 10 captures the position of the battery cell 9 on the positioning panel 5 and provides the distance that the battery cell 9 needs to be adjusted in the X direction, the distance that needs to be adjusted in the Y direction, or the angle that the battery cell 9 needs to be rotated to correct its position. When the X-direction position needs to be adjusted, the screw nut mechanism 1 drives the hollow table 3 to move in the X direction; when the angle needs to be adjusted, the hollow rotating platform 7 drives the light source base plate 4 to rotate, synchronously driving the positioning panel 5 to rotate the required angle to correct the position of the battery cell 9.

[0028] After the battery cell 9 is positioned correctly, the direct connection module 18 drives the transplanting plate 19 to move in the Y direction according to the distance that needs to be adjusted for the battery cell 9 in the Y direction. The slide cylinder 21 drives the suction cup assembly 12 to descend. After the four suction cups 12-2 simultaneously suck the battery cell 9, the slide cylinder 21 drives the suction cup assembly 12 to rise, and the direct connection module 18 drives the transplanting plate 19 to move, and the battery cell 9 is moved to the next process.

[0029] Since there may be defective battery cells 9, a waste box 26 is installed at the bottom of the camera frame 22 facing the output end of the belt conveyor 8. If the battery cell 9 photographed by the industrial camera 10 does not meet the requirements, the belt conveyor 8 directly transfers the defective battery cell 9 into the waste box 26.

[0030] During the use of the positioning platform of the above structure, according to the shooting results of the industrial camera 10, it is only necessary to adjust the X-direction movement and the circumferential position rotation of the battery cell 9 placed on the positioning panel 5, while the position adjustment of the battery cell 9 in the Y direction is achieved by moving the suction cup assembly 12 in the Y direction, thereby simplifying the mechanical structure of the positioning platform and correspondingly reducing the complexity of the control logic system.

[0031] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
