Abstract
Description
Technical Field
[0001] This disclosure relates to the field of battery cell printing equipment technology, and in particular to a fully automatic laser printing equipment. Background Technology
[0002] Photovoltaic silicon wafers, as the core and high-value component of solar power generation systems, bear the crucial task of converting solar energy into electrical energy. This converted energy can be stored in batteries or directly power the load. However, the current field of silicon wafer printing equipment faces numerous unresolved issues.
[0003] From a printing method perspective, most equipment employs a screen printing process where a paste is coated onto a screen, and a squeegee applies pressure from top to bottom and moves laterally, forcing the paste through the screen grooves and onto designated locations on the silicon wafer. However, this process has significant drawbacks. First, it consumes a large amount of material, increasing production costs. Second, it is prone to screen clogging, affecting the continuity of printing. Third, the screen printing line width is limited, making it difficult to meet the increasingly refined production demands; currently, the minimum printing width for solar cell sub-grid lines can only reach 20 micrometers or more. Furthermore, the downward pressure of the squeegee in contact with the solar cell easily causes problems such as cell breakage and microcracks. These drawbacks are becoming increasingly prominent in the photovoltaic industry, driven by the trend towards thinner solar cells and stricter cost control.
[0004] Some equipment uses a semi-automatic laser transfer method, but this method requires a lot of manual intervention, resulting in extremely low product output. In addition, the paste needs to be replenished manually, which seriously affects the production process and product qualification rate. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0063] Example
[0064] like Figure 1-13 As shown, this embodiment provides a fully automatic laser printing equipment, including a mounting platform 100. In this embodiment, the mounting platform 100 is a marble platform. By utilizing the high rigidity, high precision, and low deformation characteristics of the marble platform, a stable foundation is provided for laser printing, ensuring the stability and precision of the printing process.
[0065] like Figure 3 As shown, a carrier plate turntable module 200 is provided in the middle of the mounting platform 100. The carrier plate turntable module 200 includes a rotating component 201 and a turntable 202. The rotating component 201 drives the turntable 202 to rotate 90 degrees each time. Multiple mounting slots 203 are distributed in a circular array around the turntable 202. A carrier plate 204 is placed on the mounting slot 203. The carrier plate 204 is a transparent carrier plate 204. Fine grooves are engraved on the carrier plate 204 to accommodate silver paste. In this embodiment, two mounting slots 203 are grouped together. A group of mounting slots 203 is set every 90 degrees on the turntable 202. The positions corresponding to each group of mounting slots 203 are the first station, the second station, the third station, and the fourth station.
[0066] Specifically, above the first workstation, a laser optical path module 300 is positioned directly above the carrier plate 204. The laser optical path module 300 can perform laser processing on the product according to the set requirements. The laser optical path module 300 emits a laser to irradiate the transparent carrier plate 204, and the silver paste on the transparent carrier plate 204 will fall into the battery cell below under the action of the laser beam to form a grid pattern.
[0067] like Figure 4As shown, a fixture positioning module 400 is provided below the first workstation. The fixture positioning module 400 is used to place the battery cells and adjust their positions. Specifically, the fixture positioning module 400 includes a first rotating unit 401, a three-axis moving unit 402, a second rotating unit 403, and a fixture 404. The first rotating unit 401 is a conventional rotary drive structure, such as a motor-driven rotation, as long as it can achieve 180-degree rotation. The three-axis moving unit 402 consists of a structure for linear motion along the X, Y, and Z axes. It can be implemented using a lead screw motor combined with a guide rail slider. This is a conventional motion structure, and its specific structure and working principle will not be described in detail here. It is only necessary to know that it can drive... The moving fixture 404 can move along the XYZ three axes. The second rotating unit 403 works similarly to the first rotating unit 401 and can be driven to rotate by a motor. There are four fixtures 404, arranged in a rectangular array. Every time the first rotating unit 401 rotates 180 degrees, two of the fixtures 404 can be moved to the area below the first station for printing. The other two fixtures 404 are used for loading materials outside the first station. Before printing, the position and angle of the fixtures 404 are adjusted by the three-axis moving unit 402 and the second rotating unit 403. This adjustment is based on the position and angle of the battery cells placed on the fixtures 404, so that the battery cells are positioned more accurately when they move to the area below the transparent carrier plate 204 as the fixtures 404 rotate 180 degrees.
[0068] Furthermore, the surface of the fixture 404 is provided with multiple air holes 405, and the side of the fixture 404 is provided with an air vent 405 that communicates with the air holes 405. The air vent 405 is used to connect to a suction device. When the battery cell moves to the surface of the fixture 404, the suction device draws air to create a negative pressure that holds the battery cell in place, preventing it from shifting and changing position. When it is necessary to remove the processed battery cell, the suction device blows air to a certain height to facilitate unloading.
[0069] like Figure 5 As shown, a camera positioning module 500 is provided above the fixture positioning module 400. The camera positioning module 500 consists of multiple cameras, which are used to detect the position and angle of the battery cells placed on the fixture 404. Then, the fixture positioning module 400 adjusts the position of the battery cells according to the detected images, so that the position is correct after rotating 180 degrees, thereby improving the processing accuracy.
[0070] like Figure 6-7As shown, a feeding and conveying module 600 is provided at one end of the fixture positioning module 400. The feeding and conveying module 600 consists of two feeding conveyor belts 601. A stop block 602 is provided in the middle of the two feeding conveyor belts 601 near the fixture 404. When the battery cell moves on the feeding conveyor belt 601, it will be blocked when it reaches the position of the stop block 602 and will not continue to move forward. It waits for the loading and unloading interaction module 800 to move the battery cell onto the fixture 404.
[0071] Furthermore, it also includes an adjustment module 603, which includes an adjustment motor 6031, a synchronous belt assembly 6032, two synchronous belt clamps 6033, two sliding seats 6034, two adjustment plates 6035, and rollers 6036. The adjustment motor 6031 is drivenly connected to the synchronous belt assembly 6032. The two synchronous belt clamps 6033 are respectively fixed on both sides of the synchronous belt assembly 6032. The two sliding seats 6034 are respectively connected to the synchronous belt clamps 6033. The two adjustment plates 6035 are respectively fixed on the top of the sliding seats 6034. Each adjustment plate 6035 has two rollers 6036 rotatably connected to its surface. The adjustment motor 6031 drives the synchronous belt assembly 6032 to move, causing the two adjustment plates 6035 to move closer or further apart. When the battery cell reaches the position of the stop block 602, the synchronous belt assembly 6032 is driven by the motor 6031 to move, which in turn drives the two synchronous belt clamps 6033 to move in opposite directions, thereby moving the two sliding seats 6034 and bringing the two adjusting plates 6035 closer together. The rollers 6036 then squeeze the battery cell, making the battery cell position more neat.
[0072] like Figure 8As shown, a discharge conveying module 700 is provided at one end of the fixture 404 away from the loading conveying module 600. The discharge conveying module 700 includes a fourth linear motion unit 701, a discharge conveyor belt 702, and an air-floating platform 703. The fourth linear motion unit 701 is fixed to the mounting platform 100. The fourth linear motion unit 701 is existing technology, and it only needs to be able to drive the discharge conveyor belt 702 and the air-floating platform 703 to move back and forth. Its specific structure and working principle will not be described in detail here. The fourth linear motion unit 701 drives the discharge conveyor belt 702 to move closer to or away from the fixture positioning module 400. The air-floating platform 703 is fixed to the surface of the discharge conveyor belt 702, and the horizontal height of the air-floating platform 703 is lower than the horizontal height of the discharge conveyor belt 702. When the processed battery cells are ready to be unloaded, the suction device blows air to lift the battery cells located on the fixture 404, achieving a suspended state. At the same time, the air flotation platform 703 also works. The fourth linear motion unit 701 drives the unloading conveyor belt 702 and the air flotation platform 703 to approach the fixture 404, so that the air flotation platform 703 and the fixture 404 are connected. The loading and unloading interaction module 800 pushes the battery cells from the fixture 404 to above the unloading conveyor belt 702. At this time, the air flotation platform 703 continues to work to keep the battery cells suspended, preventing them from falling before reaching the designated position. After reaching the designated position, the air flotation platform 703 stops working, and the battery cells fall onto the unloading conveyor belt 702 for unloading. After unloading is completed, the fourth linear motion unit 701 drives the unloading conveyor belt 702 and the air flotation platform 703 away from the fixture 404 to avoid affecting the rotation of the fixture 404.
[0073] like Figure 9-10 As shown, the loading / unloading interaction module 800 includes a first linear motion unit 801, a first moving fixture, and a second moving fixture. The first linear motion unit 801 is fixed to the mounting platform 100 and is used to drive the first and second moving fixtures to move. The first linear motion unit 801 is a conventional technology; any unit capable of driving the first and second moving fixtures to perform linear motion is sufficient. The first moving fixture is used to move the battery cells from the loading conveyor belt 601 to the fixture 404, and the second moving fixture is used to move the battery cells from the fixture 404 to the unloading conveyor belt 702.
[0074] Specifically, the first movable fixture includes a first movable frame 802, a first fixed plate 803, and Bernoulli suction cups 804. The first movable frame 802 is connected to the first linear motion unit 801. The first fixed plate 803 is fixed to the top of the first movable frame 802. Multiple Bernoulli suction cups 804 are fixed to the first fixed plate 803. The first movable frame 802 is driven by the first linear motion unit 801 to move to the position of the feeding conveyor belt 601. Then, the Bernoulli suction cups 804 pick up the battery cells. The first linear motion unit 801 drives the first movable frame 802 to move to the position of the fixture 404. The Bernoulli suction cups 804 place the battery cells on the fixture 404.
[0075] Specifically, the second movable fixture includes a second movable frame 805, a second fixed plate 806, and multiple limiting blocks 807. The second movable frame 805 is drivenly connected to the first linear motion unit 801. The second fixed plate 806 is fixed to the top of the second movable frame 805, and the limiting blocks 807 are fixed around the bottom of the second fixed plate 806. The area formed between the four limiting blocks 807 is used to place the battery cells. During unloading, the first linear motion unit 801 drives the second movable frame 805 to move to the position of the fixture 404. At this time, the fixture 404 blows air through the suction device to lift the battery cells, so that the battery cells are embedded between the four limiting blocks 807. The first linear motion unit 801 drives the second movable frame 805 to move towards the downward conveyor belt 702, pushing the battery cells to move towards the downward conveyor belt 702. After moving to the designated position, the air flotation platform 703 on the unloading conveyor belt 702 stops working, and the battery cells fall onto the unloading conveyor belt 702 for unloading.
[0076] like Figure 11 As shown, a cleaning module 900 is set at the second workstation. The cleaning module 900 includes a cleaning lifting unit 903, an ultrasonic cleaning chamber 901, and a laser cleaning unit 902. The cleaning lifting unit 903 is fixed to the mounting platform 100 and drives the ultrasonic cleaning chamber 901 to move up and down via a cylinder. The laser cleaning unit 902 is fixed to the mounting platform 100 and located above the ultrasonic cleaning chamber 901. After printing, the transparent carrier plate 204 at the second workstation has residual silver paste on it, which needs to be cleaned first. The cleaning lifting unit 903 drives the ultrasonic cleaning chamber 901 to rise, so that the transparent carrier plate 204 is immersed in the ultrasonic cleaning chamber 901 for cleaning. In addition, the laser cleaning unit 902 is set above the carrier plate 204 for laser cleaning. This double cleaning ensures the accuracy of the next processing.
[0077] like Figure 12As shown, a drying module 110 is set at the third workstation. The drying module 110 includes a second linear motion unit 111, a drying moving seat 112, a drying lifting unit 113, a dehumidification box 114, and a scraper 116. The second linear motion unit 111 is fixed to the mounting platform 100. The second linear motion unit 111 is a conventional technology, which only needs to be able to drive the drying moving seat 112 to move back and forth. Its specific structure and working principle will not be described in detail here. The drying moving seat 112 and the... The second linear motion unit 111 is connected by transmission. The drying lifting unit 113 is fixed to the drying moving seat 112. The drying lifting unit 113 is a cylinder. In this embodiment, there are two drying lifting units 113, which correspond to the positions of the two carrier plates 204 respectively. The dehumidification box 114 is fixed to the top of the drying lifting unit 113. The side of the dehumidification box 114 is fixed with an air extraction port 115. The air extraction port 115 is used to connect to a negative pressure device. The scraper 116 is fixed to the side of the dehumidification box 114. When the cleaned carrier plate 204 moves to the third station, the dehumidification box 114 is driven to rise by the drying lifting unit 113, so that the scraper 116 and the bottom of the carrier plate 204 are set together. At this time, the scraper 116 is driven to move by the second linear motion unit 111 to scrape off the residual liquid at the bottom of the carrier plate 204. At the same time, the negative pressure equipment connected to the air extraction port 115 is started to extract air, so that the scraped liquid is sucked into the dehumidification box 114, thus completing the drying operation of the carrier plate 204.
[0078] like Figure 13As shown, a coating module 120 is installed at the fourth workstation. The coating module 120 includes a third linear motion unit 121, a base plate 122, a coating lifting unit 123, a coating unit, a doctor blade lifting unit 125, and a doctor blade 125 unit. The third linear motion unit 121 is existing technology; it only needs to drive the base plate 122 to move back and forth. Its specific structure and working principle will not be described in detail here. The base plate 122 is connected to the third linear motion unit 121. The coating lifting unit 123 and the doctor blade lifting unit 125 are respectively fixed to the surface of the base plate 122. The coating unit is driven by a cylinder for lifting. The coating lifting unit 123 drives the coating unit to lift and lower, and the doctor blade lifting unit 125 drives the doctor blade 1253 unit to lift and lower. The coating unit includes a coating motor 1241, a transmission synchronization structure 1242, and two coating rollers 1243. The coating motor 1241 drives the two coating rollers 1243 to rotate through the transmission synchronization structure 1242. The doctor blade 1253 unit includes a doctor blade motor 1251, a doctor blade rotating shaft 1252, and a doctor blade 1253. The doctor blade rotating shaft 1252 is connected to the doctor blade motor 1251 for transmission, and the doctor blade 1253 is fixed to the doctor blade rotating shaft 1252. During coating, the coating unit is driven to rise by the coating lifting unit 123, and the coating motor 1241 drives the two coating rollers 1243 to rotate, causing the silver paste on the coating rollers 1243 to adhere to the carrier plate 204.

The doctor blade motor 1251 drives the doctor blade rotation shaft 1252 to rotate, causing the doctor blade 1253 to rotate and scrape off the excess silver paste at the bottom of the carrier plate 204. After coating is completed, the carrier plate 204 continues to rotate and returns to the first station for printing.
[0079] The working principle of this utility model is as follows: The battery cells are fed through the feeding conveyor belt 601. The loading and unloading interaction module 800 transfers the battery cells to the fixture 404. The camera positioning module 500 takes a picture of the battery cell placement. The fixture positioning module 400 moves the driving fixture 404 to adjust the position of the battery cells according to the picture information. After the position is adjusted, the fixture positioning module 400 rotates 180 degrees and moves the placed battery cells under the carrier plate 204. The laser beam is emitted by the laser optical path module 300 for laser printing. After the printing is completed, the fixture positioning module 400 continues to rotate 180 degrees. The loading and unloading interaction module 800 moves the printed battery cells to the unloading conveyor module 700 for unloading. Furthermore, after printing is completed, the carrier plate turntable module 200 rotates 90 degrees to move the used carrier plate 204 to the cleaning module 900 for cleaning. After cleaning, the carrier plate turntable module 200 continues to rotate 90 degrees to move to the drying module 110 for drying, and then continues to rotate 90 degrees to move to the coating module 120 for silver paste coating. After coating is completed, it continues to rotate 90 degrees and returns to the first station for printing. All four stations can work simultaneously, greatly improving work efficiency.
