Description

Technical Field

[0001] This utility model relates to the field of solar cell fabrication technology, specifically to a positive sheet preparation device for solar cells. Background Technology

[0002] Solar energy is a renewable energy source, referring to the thermal radiation energy of the sun, mainly manifested as sunlight. In modern times, it is generally used for power generation or to provide energy for water heaters. A solar cell is a photoelectric semiconductor thin film that directly generates electricity using sunlight. It is also known as a "solar chip" or "photovoltaic cell". As long as it is provided with sufficient illuminance, it can instantly output voltage and generate current when there is a circuit.

[0003] Chinese Patent CN213922969U discloses a solar cell alignment system for transmission, including a fine-tuning alignment device. This device, driven by a drive unit, performs inward alignment and outward repositioning of the solar cells. At least one pair of coarse-tuning alignment devices precedes the fine-tuning alignment device. This invention allows for multiple corrections or adjustments to the solar cells as they travel on the transmission device, preventing them from deviating from their intended path. It also expands the alignment adjustment range and amplitude. Solar cells with significant deviations can gradually return to the center of the channel after passing through the coarse-tuning alignment device, with their angle gradually returning to normal and the degree of deviation decreasing. Then, through the fine-tuning alignment device, their position and angle are completely corrected, thus preventing solar cell deviation.

[0004] However, the above technical solution has the following drawbacks: In the above positive cell transfer system, the cells are coarsely adjusted by continuous collisions, and then fine adjustment is required by the positive cell adjustment device. The adjustment stroke is long, and the corners of the cells will be damaged by repeated collisions, reducing the pass rate of the cells. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a positive sheeting device for solar cells, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a solar cell positive sheet device, including a mounting frame, a bracket fixedly connected to the bottom of the mounting frame, and a transmission roller provided on the mounting frame; a U-shaped plate first fixedly connected to the top of the mounting frame, and a camera provided inside the U-shaped plate first; a positive sheet mechanism provided at the bottom of the mounting frame, the positive sheet mechanism including a U-shaped plate second, a lead screw, and a moving block; the U-shaped plate second fixedly connected to the bottom of the mounting frame; the lead screw passing through the moving block and threadedly connected to the moving block; an electric push rod fixedly installed on the top of the moving block; a connecting plate fixedly installed on the top of the electric push rod; a motor second fixedly installed on the top of the connecting plate; and a support plate fixedly connected to the output shaft of the motor second.

[0007] Preferably, a motor is fixedly installed on the front side of the second U-shaped plate, the output shaft of the motor is fixedly connected to the front end of the lead screw, and the rear end of the lead screw is rotatably connected to the back side of the inner wall of the second U-shaped plate through a bearing.

[0008] Preferably, a limiting rod is fixedly connected inside the U-shaped plate 2, and the limiting rod passes through the moving block and is slidably connected to the moving block.

[0009] Preferably, the tray is provided with an adsorption mechanism, which includes a suction cup. The top of the tray has a groove and an interior cavity. The bottom of the suction cup extends through the bottom of the inner wall of the groove into the interior of the cavity and is fixedly connected to the tray.

[0010] Preferably, a vacuum pump is fixedly installed on the front of the tray, and a connecting pipe is installed on the back of the vacuum pump, with one end of the connecting pipe located inside the cavity.

[0011] Preferably, a connecting pipe is provided on the back of the tray, and the connecting pipe is connected to the cavity, and a solenoid valve is provided on the connecting pipe.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. The solar cell positive sheet device uses a starting motor to drive a lead screw to rotate, which in turn moves a moving block back and forth, aligning the tray with the position of the solar cell during transport. Then, an electric push rod is activated to precisely lift the passing solar cell. Next, a second motor is activated to drive the tray to rotate, adjusting the angle of the solar cell. Finally, an electric push rod is activated to lower the solar cell, and the transmission roller can then transport the positively oriented solar cell. This device prevents collisions and damage to the solar cell, thus improving the yield rate of the solar cell.

[0014] 2. The positive sheet device of this solar cell, when the solar cell is raised, starts the vacuum pump and uses the connecting pipe to evacuate the inside of the cavity, thereby causing the suction cup to generate suction force. The suction cup adsorbs the solar cell on the top of the tray, preventing it from falling off during positive sheeting and improving the stability of the positive sheet. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] Please see Figure 1-3 One embodiment of this utility model is as follows: a solar cell positive-shaving device includes a mounting frame 1, a bracket 3 fixedly connected to the bottom of the mounting frame 1, and multiple transmission rollers 2 arranged linearly at equal intervals on the mounting frame 1, which are driven to rotate by a drive mechanism (not shown in the prior art). A U-shaped plate 4 is fixedly connected to the top of the mounting frame 1, and a camera is installed inside the U-shaped plate 4. The camera can photograph the passing solar cells to determine whether the solar cells need positive shaving. A positive-shaving mechanism 5 is provided at the bottom of the mounting frame 1. The positive-shaving mechanism 5 includes a U-shaped plate 51, a lead screw 52, ​​and a moving block 54. The U-shaped plate 51 is fixedly connected to the bottom of the mounting frame 1. The lead screw 52 passes through the moving block 54 and is threadedly connected to the moving block 54. An electric push rod 56 is fixedly installed on the top of the moving block 54, and a connecting plate 57 is fixedly installed on the top of the electric push rod 56. A second motor 58 is fixedly installed on the top of the device. The output shaft of the second motor 58 is fixedly connected to a support plate 59. A first motor 53 is fixedly installed on the front side of the second U-shaped plate 51. The output shaft of the first motor 53 is fixedly connected to the front end of a lead screw 52, ​​and the rear end of the lead screw 52 is rotatably connected to the back of the inner wall of the second U-shaped plate 51 through a bearing. A limit rod 55 is fixedly connected inside the second U-shaped plate 51. The limit rod 55 passes through a moving block 54 and is slidably connected to the moving block 54. The limit rod 55 makes the moving block 54 move back and forth stably and horizontally. After the camera captures and judges the image, it transmits the signal to the first motor 53, the second motor 58, and the electric push rod 56, so that the first motor 53 starts to adjust the position of the support plate 59, and the electric push rod 56 starts to lift or lower the battery cell. When the position of the battery cell deviates, after lifting the battery cell, the first motor 53 is started to drive the battery cell back to the center position of the device for positive cell transmission. The second motor 58 starts to adjust the angle of the battery cell.

[0024] Working principle: The solar cells are transported from left to right by the transmission roller 2. During the transport, the camera captures and judges the position of the cells. The motor 1 53 is started to drive the lead screw 52 to rotate. The lead screw 52 drives the moving block 54 to move back and forth, so that the support plate 59 is aligned with the position of the cells. Then, the electric push rod 56 is started to precisely lift the passing cells. Then, the motor 2 58 is started to drive the support plate 59 to rotate. The support plate 59 adjusts the angle of the cells. Then, the electric push rod 56 is started to lower the cells. The transmission roller 2 can then transport the solar cells after they have been aligned.

[0025] Please see Figure 2-3 Based on the above embodiments, in another embodiment of this utility model, the tray 59 is provided with an adsorption mechanism 6, which includes a suction cup 65. The top of the tray 59 has a groove 61, and the interior has a cavity 62. The bottom of the suction cup 65 extends through the bottom of the inner wall of the groove 61 into the cavity 62 and is fixedly connected to the tray 59. The suction cup 65 communicates with the cavity 62, and there are two suction cups. The top of the suction cup 65 is flush with the top of the tray 59, allowing the tray 59 to stably lift the battery cell. A vacuum pump 63 is fixedly installed on the front of the tray 59, and a connecting pipe 64 is installed on the back of the vacuum pump 63. One end of the connecting pipe 64 is located inside the cavity 62. A connecting pipe 66 is provided on the back of the tray 59 and is connected to the cavity 62. A solenoid valve 67 is provided on the connecting pipe 66. The opening and closing of the connecting pipe 66 can be controlled by the solenoid valve 67. When it is necessary to release the adsorbed battery cell, the solenoid valve 67 is opened to make the pressure inside and outside the cavity 62 quickly equalize, thereby quickly releasing the battery cell.

[0026] Working principle: When the solar cell is lifted to the positive position, the vacuum pump 63 is started and the cavity 62 is evacuated through the connecting pipe 64, thereby causing the suction cup 65 to generate suction force. The suction cup 65 adsorbs the solar cell onto the top of the tray 59, preventing it from falling off during positive positioning and improving the stability of the positive position.

[0027] It is worth noting that all the technologies not described in the above manual are existing technologies and are not the main innovations, so they will not be described in detail here.

[0028] This utility model provides a positive sheeting device for solar cells. There are many methods and approaches to implement this technical solution; the above is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
