Description

Technical Field

[0001] This utility model relates to the field of visual positioning technology, specifically a visual positioning device for battery cells. Background Technology

[0002] Solar cells are generally classified into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells are currently the fastest-developing type of solar cell; their structure and manufacturing process are well-established, and the products are widely used in space and on the ground. These solar cells use high-purity monocrystalline silicon rods as raw materials. To reduce production costs, ground-based solar cells use solar-grade monocrystalline silicon rods, with relaxed material performance specifications. Some also utilize the head and tail materials from semiconductor device processing and waste monocrystalline silicon materials, which are then re-drawn into monocrystalline silicon rods specifically for solar cells.

[0003] Currently, most photovoltaic manufacturers use screen printing to prepare electrodes and electric fields for solar cells. This requires the solar cells to be aligned with the screen printing stencil. This alignment requires high precision, and the solar cells need to be accurately measured and positioned before alignment. During the positioning process, visual positioning is usually achieved by taking pictures with a camera. However, in the existing technology, the position of the camera is not easy to adjust. When the camera position is too high, the proportion of the solar cells in the image is low. When the camera position is too low, it is impossible to accurately capture and record the position data of the four right-angled edges of the solar cells. Therefore, a solar cell visual positioning device is proposed. Utility Model Content

[0020] 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 protection scope of the present utility model.

[0021] Example 1:

[0022] Please refer to the following: Figures 1-5 This utility model provides a technical solution: a battery cell visual positioning device, including a conveyor 1. The conveyor 1 includes two side plates. A first gantry frame 2 is fixedly connected to the top outer surface of the two side plates of the conveyor 1. Two cylinders 3 are fixedly installed on the top outer surface of the first gantry frame 2. A first electromagnetic slide rail 4 is fixedly installed at the output end of the two cylinders 3. An adjusting seat 5 is fixedly installed at the output end of the first electromagnetic slide rail 4. A first motor 6 is fixedly installed on the top inner surface of the adjusting seat 5. A threaded rod 7 is fixedly connected to the output end of the first motor 6. A threaded cylinder 8 is threadedly sleeved on the outer surface of the threaded rod 7. A mounting plate 9 is fixedly connected to the bottom outer surface of the threaded cylinder 8. A positioning camera 10 is fixedly installed. A first laser rangefinder is installed at each of the four corners of the positioning camera 10 on the mounting plate 9. Specifically, the height of the positioning camera 10 is adjusted according to the size of the battery cell. At this time, the height of the positioning camera 10 is initially adjusted by the cylinder 3. Then, the first motor 6 is turned on. The first motor 6 drives the threaded rod 7 to rotate. The threaded rod 7 drives the threaded cylinder 8 to move, so as to precisely adjust the height of the positioning camera 10. The lateral position of the positioning camera 10 is adjusted by the first electromagnetic slide rail 4. Then, the battery cell is transported from the conveyor 1. When the first laser rangefinder detects a change in distance, the positioning camera 10 takes a picture of the battery cell and precisely positions the four sides of the battery cell.

[0023] In this embodiment, a second gantry frame 11 is fixedly connected to the top outer surface of the two side plates of the conveyor 1. The second gantry frame 11 is located behind the first gantry frame 2. A second electromagnetic slide rail 12 is fixedly installed on the top downward outer surface of the second gantry frame 11. A first electric push rod 13 is fixedly installed at the output end of the second electromagnetic slide rail 12. Specifically, the lateral position of the electric suction cup 18 is adjusted by the second electromagnetic slide rail 12, and the electric suction cup 18 is driven to contact the battery cell by the first electric push rod 13.

[0024] In this embodiment, a fixing plate 14 is fixedly connected to the output end of the first electric push rod 13. The four corners of the fixing plate 14 are cut into mounting surfaces, and a second electric push rod 15 is fixedly mounted on each of the four mounting surfaces. A second laser rangefinder 16 is fixedly mounted on the output end of each of the second electric push rods 15. A second motor 17 is fixedly mounted on the bottom outer surface of the fixing plate 14, and an electric suction cup 18 is fixedly mounted on the output end of the second motor 17. Specifically, when the second electric push rod 15 is activated, it moves the second laser rangefinder 16, causing the second laser rangefinder 16 to be approximately positioned at the four corners of the battery cell. When all four second laser rangefinders 16 have detected a distance... When the distance changes, the conveyor 1 continues to transport the battery cells. When at least one of the four second laser rangefinders 16 senses a change in distance, the first electric push rod 13 is activated. The first electric push rod 13 drives the electric suction cup 18 to contact the battery cell and adsorb it. The position of the electric suction cup 18 is adjusted by the second electromagnetic slide rail 12, and the battery cell is rotated by the second motor 17 to adjust its position until the distance sensed by the four second laser rangefinders 16 is consistent. A signal is then sent to the controller, which receives the signal and causes the electric suction cup 18 to put the battery cell down and transport it by the conveyor 1.

[0025] In this embodiment, two telescopic rods are fixedly connected to the top inner surface of the adjusting seat 5, and a limiting plate is fixedly sleeved on the outer surface of the threaded cylinder 8. The bottom ends of the two telescopic rods are fixedly connected to the limiting plate. Specifically, when the first motor 6 drives the threaded rod 7 to rotate, it drives the threaded cylinder 8 to move, so that the limiting plate drives the telescopic rod, and the telescopic rod extends and retracts accordingly, so as to prevent the threaded cylinder 8 from rotating with the rotation of the threaded rod 7.

[0026] In this embodiment, a controller is fixedly installed on the side plate of the conveyor 1. Specifically, the controller controls the operation of the device.

[0027] Working principle: When using this utility model, the height of the positioning camera 10 is adjusted according to the size of the battery cell. At this time, the height of the positioning camera 10 is initially adjusted by the cylinder 3, and then the first motor 6 is turned on. The first motor 6 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the threaded cylinder 8 to move, so as to precisely adjust the height of the positioning camera 10. The lateral position of the positioning camera 10 is adjusted by the first electromagnetic slide rail 4. Then the battery cell is transported from the conveyor 1. When the first laser rangefinder detects a change in distance, the positioning camera 10 takes a picture of the battery cell and precisely positions the four sides of the battery cell.

[0028] As the conveyor 1 transports the battery cells, when they reach the second gantry frame 11, the second electric push rod 15 is activated according to the size of the battery cell. The second push rod drives the second laser rangefinder 16 to move, so that the second laser rangefinder 16 is roughly located at the four corners of the battery cell. When none of the four second laser rangefinders 16 senses a distance change, the conveyor 1 continues to transport the battery cell. When at least one of the four second laser rangefinders 16 senses a distance change, the first electric push rod 13 is activated. The first electric push rod 13 drives the electric suction cup 18 to contact the battery cell and adsorb it. The position of the electric suction cup 18 is adjusted by the second electromagnetic slide rail 12, and the position of the battery cell is adjusted by the second motor 17 to rotate the battery cell until the distances sensed by the four second laser rangefinders 16 are consistent. A signal is then sent to the controller, which receives the signal and causes the electric suction cup 18 to put down the battery cell, which is then transported by the conveyor 1.

[0029] The controller is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
