Description

Technical Field

[0001] This application relates to the field of photovoltaic cell module production equipment, and more particularly to a cell printing table and a printing device. Background Art

[0002] During the production process of a cell module, it is necessary to print a conductive material on the surface of a cell to form grid lines configured to collect current. To improve printing efficiency, a cell printing table can simultaneously move two cells to be printed carried thereon to a printing mechanism, so that the printing mechanism can synchronously print the two cells each time.

[0003] For existing cell printing tables, the position adjustment of the cells cannot be implemented. After two cells to be printed are placed on the cell printing table, their relative positions cannot be adjusted. When the relative positions of the two cells to be printed do not meet the printing requirements, the printing screen of the printing mechanism can only be aligned with one of the cells to be printed, ultimately resulting in the printing quality of the other cell to be printed not meeting the requirements.

[0020] A three-axis alignment platform with a simple structure and stable driving is provided, which can drive the corresponding printing table to translate and rotate on a horizontal plane to achieve printing alignment.

[0023] In some embodiments, the printing device further includes a driving mechanism, and the solar cell printing table is connected to a moving part of the driving mechanism; the driving mechanism is configured to drive the solar cell printing table to reciprocate between the first input mechanism and the first output mechanism, so that the solar cell printing table receives at least two solar cells to be printed from the first input mechanism, conveys at least two solar cells to be printed to the first printing station, and conveys at least two printed solar cells to the first output mechanism; the first printing mechanism is arranged above the first printing station.

[0052] To make the above objects, features, and advantages of the present application more apparent and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0053] In the existing solar cell printing table, the position adjustment of the solar cells cannot be implemented. After two solar cells to be printed are placed on the solar cell printing table, their relative positions cannot be adjusted.

[0054] In view of this, the present application provides a solar cell printing table, which includes a carrier table and at least two printing tables arranged on the carrier table, wherein: each printing table is used to carry a solar cell to be printed; at least one printing table is provided with an independent three-axis alignment platform, and the three-axis alignment platform is configured to adjust the position of the printing table.

[0055] In the solar cell printing table provided by the present application, since at least one printing table thereon is connected to the movable part of the three-axis alignment platform, the corresponding printing table is driven by the three-axis alignment platform to translate and rotate on the horizontal plane, so as to realize the position adjustment of the solar cell located on the printing table, so that the relative positions of the solar cells on the solar cell printing table meet the printing requirements, and finally ensure the printing quality of each solar cell.

[0056] As Figures 1 to 2 shown, optionally, in the solar cell printing table 10 in the embodiment of the present application, two printing tables are arranged on the carrier table 1, namely the first printing table 2 and the second printing table 3. Among them, the first printing table 2 is fixedly arranged on the carrier table 1. The three-axis alignment platform 4 is arranged on the carrier table 1, and the second printing table 2 is connected to the movable part of the three-axis alignment platform 4. The three-axis alignment platform 4 is configured to drive the second printing table 3 to translate and rotate on the horizontal plane to adjust the position of the solar cell located on the second printing table 3.

[0057] The optional working process of the solar cell printing table 10 in the embodiment of the present application and the printing mechanism is as follows:

[0058] First, two battery wafers are respectively loaded onto the first printing table 2 and the second printing table 3, and the positioning camera is controlled to take pictures and position the battery wafers on the first printing table 2 and the second printing table 3.

[0059] Next, the battery wafer printing table 10 is moved as a whole under the printing mechanism, and the printing mechanism adjusts the position of the screen plate according to the position information of the battery wafer on the first printing table 2, so that the first printing area on the screen plate is aligned with the battery wafer on the first printing table 2.

[0060] Next, the three-axis alignment platform 4 adjusts the position of the battery wafer on the second printing table 3 according to the position information of the battery wafer on the second printing table 3, so that the second printing area on the screen plate is aligned with the battery wafer on the second printing table 3. At this point, the two printing areas on the screen plate are respectively aligned with the battery wafers on the first printing table 2 and the second printing table 3. The printing mechanism performs synchronous printing on the battery wafers on the first printing table 2 and the second printing table 3, which can ensure the printing quality of the two battery wafers.

[0061] Optionally, the first printing table 2 includes a first carrier plate 21. The first carrier plate 21 is buckled with the carrier 1 to form a first air cavity. A number of first suction holes 22 communicating with the first air cavity are provided on the first carrier plate 21. The first air cavity is configured to pump air from the first suction holes 22, so that the first carrier plate 21 adsorbs the battery wafer located on the first carrier plate 21 through the first suction holes 22, preventing the battery wafer located on the first carrier plate 21 from sliding during the printing process and affecting the printing quality.

[0062] Optionally, a first light source is provided in the first air cavity, and the first carrier plate 21 is made of a light-transmitting material. The first light source can irradiate the battery wafer located on the first carrier plate 21 through the first carrier plate 21, so that the positioning camera can accurately position the battery wafer located on the first carrier plate 21, ensuring that the printing mechanism can adjust the position of the screen plate according to the position information of the battery wafer on the first carrier plate 21, so that the first printing area of the screen plate is aligned with the battery wafer located on the first carrier plate 21.

[0063] Optionally, the second printing table 3 includes a base body 31 and a second carrier plate 32, where: the base body 31 is connected to the moving part of the three-axis alignment platform 4, a deep groove is formed on the base body 31, the second carrier plate 32 covers the deep groove and forms a second air cavity with the deep groove, and a number of second suction holes 33 communicating with the second air cavity are provided on the second carrier plate 32. The second air cavity is configured to pump air from the second suction holes 33, so that the second carrier plate 32 adsorbs the battery wafer located on the second carrier plate 32 through the second suction holes 33, preventing the battery wafer located on the second carrier plate 32 from sliding during the printing process and affecting the printing quality.

[0064] Optionally, a second light source is provided in the second air chamber, and the second carrier plate is made of a light-transmitting material. The second light source irradiates the solar cell located on the second carrier plate 32 through the second carrier plate 32, so that the positioning camera can accurately position the solar cell located on the second carrier plate 32, thereby ensuring that the three-axis alignment platform 4 can drive the second printing table 3 to translate and rotate according to the position information of the solar cell located on the second carrier plate 32, so that the second printing area on the screen is aligned with the solar cell located on the second carrier plate 32.

[0065] In other embodiments, three or other numbers of printing tables may also be provided on the carrier 1 of the solar cell printing table 10, so that the printing mechanism can synchronously print three or more solar cells. For example, when three printing tables are provided on the carrier 1 of the solar cell printing table 10, the first printing table may be fixedly arranged on the carrier 1, and the second printing table and the third printing table respectively have independent three-axis alignment platforms. Before printing, the printing mechanism adjusts the position of the screen according to the position information of the solar cell on the first printing table, so that a printing area of the screen is adapted to the position of the solar cell on the first printing table. Subsequently, the three-axis alignment platform corresponding to the second printing table and the three-axis alignment platform corresponding to the third printing table respectively perform position adjustment on the second printing table and the third printing table according to the position information of the solar cells thereon, so that the solar cells on the second printing table and the third printing table are respectively adapted to the positions of the other two printing areas of the screen. In this way, the synchronous printing quality of the three solar cells on the solar cell printing table 10 can be ensured.

[0066] As Figures 3 to 5 shown, optionally, the three-axis alignment platform 4 includes a base 41, an X-axis moving member 42, a Y-axis moving member 43 and a Z-axis rotating member 44, wherein:

[0067] The X-axis moving member 42 is slidably connected to the base 41. A first stator is provided on one of the base 41 and the X-axis moving member 42, and a first mover matching the first stator is provided on the other of the base 41 and the X-axis moving member 42. The first mover and the first stator cooperate to drive the X-axis moving member 42 to slide along the X-axis direction on the base.

[0068] The Y-axis moving member 43 is slidably connected to the X-axis moving member 42. A second stator is provided on one of the X-axis moving member 42 and the Y-axis moving member 43, and a second mover matching the second stator is provided on the other of the X-axis moving member 42 and the Y-axis moving member 43. The second mover and the second stator cooperate to drive the Y-axis moving member 43 to slide along the Y-axis direction on the X-axis moving member 42.

[0069] The Z-axis rotating member 44 is rotatably connected to the Y-axis moving member 43, one of which is provided with an annular third stator, and the other of which is provided with a third mover matched with the third stator, and the third mover cooperates with the third stator to drive the Z-axis rotating member 44 to rotate. The ink pad (e.g., the second ink pad 3) is connected to the Z-axis rotating member 44.

[0070] It can be seen that through the coordinated driving of the X-axis moving part 42, the Y-axis moving part 43 and the Z-axis rotating part 44, the three-axis alignment platform 4 can drive the ink pad to translate on the X-axis and Y-axis, and rotate around the Z-axis on the horizontal plane, thereby realizing the position adjustment of the battery cell on the ink pad.

[0071] Optionally, since the mover and stator of the linear motor move relative to each other, the position adjustment can also be achieved by exchanging the installation positions of the corresponding movers and stators in the above embodiments, which are not listed one by one for the sake of brevity.

[0072] Of course, other existing UVW alignment platforms can also be used as the three-axis alignment platform in the embodiment of the present application. For example, a certain UVW alignment platform includes three servo motors, three sets of screw modules (the screw module at least includes a screw bracket, a screw rotatably mounted on the screw bracket at both ends, and a screw nut slidably mounted on the screw) and a cross guide and a rotating shaft. Each servo motor is connected to a screw module in a transmission manner, and a cross guide is installed on the driving end (screw nut) of the screw module. The other end of the cross guide is rotatably connected to a certain point at the bottom of the ink pad through a rotating shaft. With this arrangement, the translation and rotation of the ink pad in the horizontal plane can be controlled by controlling the three servo motors.

[0073] The present application also provides a battery sheet printing device, such as Figure 6 As shown, the cell printing device includes the cell printing station 10, the first input mechanism 20, the first printing mechanism 30 and the first output mechanism 40 in any of the above embodiments, wherein:

[0074] The cell printing station 10 is located between the first input mechanism 20 and the first output mechanism 40 , and the first printing mechanism 30 is located above the cell printing station 10 .

[0075] The first input mechanism 20 is configured to synchronously convey at least two battery cells to be printed onto the battery cell printing platform 10 .

[0076] The first printing mechanism 30 is configured to perform synchronous printing on at least two battery cells located on the battery cell printing platform 10 .

[0077] The first output mechanism 40 is configured to output at least two printed battery cells.

[0078] It can be seen that through the cooperation of the first input mechanism 20, the solar cell printing table 10, the first printing mechanism 30 and the first output mechanism 40, the solar cell printing device in the embodiment of the present application realizes the synchronous printing of more than two solar cells, and realizes the automatic loading and unloading of solar cells, thereby improving the solar cell printing efficiency. In particular, since the solar cell printing table 10 can adjust the position of at least one solar cell located thereon, the relative positions of the solar cells on the solar cell printing table 10 meet the printing requirements, and finally ensure the printing quality of each solar cell.

[0079] As Figures 6 to 7 shown, optionally, the printing device in the embodiment of the present application further includes a driving mechanism 50, and the solar cell printing table 10 is connected to the movable part of the driving mechanism 50. The driving mechanism 50 is configured to drive the solar cell printing table 10 to reciprocate between the first input mechanism 20 and the first output mechanism 40, so that the solar cell printing table 10 receives at least two solar cells to be printed from the first input mechanism 20, and conveys at least two solar cells to be printed to the first printing station, and conveys at least two printed solar cells to the first output mechanism 40. The first printing mechanism 30 is arranged above the first printing station.

[0080] By setting the driving mechanism 50, the solar cell printing table 10 can reciprocate between the first input mechanism 20 and the first output mechanism 40, so that the solar cell printing table 10 can automatically receive at least two solar cells to be printed from the first input mechanism 20, convey the solar cells to be printed to the first printing station for printing, and automatically convey the printed solar cells to the first output mechanism 40 after printing.

[0081] Optionally, the driving mechanism 50 includes a translation driving part and a lifting driving part. Among them, the lifting driving part is connected to the movable part of the translation driving part, and the solar cell printing table 10 is connected to the movable part of the lifting driving part. The translation driving part is used to drive the solar cell printing table 10 to translate between the first input mechanism 20 and the first output mechanism 40, and the lifting driving part drives the solar cell printing table 10 to lift.

[0082] Optionally, both the first input mechanism 20 and the first output mechanism 40 are conveyor belt mechanisms. As Figure 8 shown, in order to enable the printing table on the solar cell printing table 10 to be docked with the conveyor belt to receive the solar cells to be printed input by the first input mechanism 20 and convey the printed solar cells to the first output mechanism 40, optionally, a conveyor belt avoidance groove 5 is provided on the printing table.

[0083] When the cell printing table 10 moves to the first input mechanism 20 under the drive of the drive mechanism 50 and reaches the position, the cell printing table 10 is located below the output end of the first input mechanism 20. Subsequently, the drive mechanism 50 drives the cell printing table 10 to rise, and the output end of the first input mechanism 20 can sink into the conveyor belt avoidance groove 5 of the printing table, so that the cells on the output end of the first input mechanism 20 fall onto the printing table.

[0084] When the cell printing table 10 moves to the first output mechanism 40 under the drive of the drive mechanism 50 and reaches the position, the input end of the first output mechanism 40 is inserted into the conveyor belt avoidance groove 5 of the printing table. Subsequently, the drive mechanism 50 drives the cell printing table 10 to descend, and the printed cells on the printing table can fall onto the input end of the first output mechanism 40.

[0085] This application also provides a cell printing device with another structure, as Figure 9 shown. The cell printing device includes at least two (for example, four) cell printing tables 10, a rotating platform 60, a second input mechanism 70, a second printing mechanism (not shown in the figure), and a second output mechanism 80 described in any of the above embodiments, where:

[0086] The cell printing tables 10 are arranged on the rotating platform 60. An input station A, a second printing station B, and an output station C are sequentially arranged on the rotation path of the rotating platform 60. The cell printing tables 10 are driven by the rotating platform to rotate to the input station A, the second printing station B, and the output station C in sequence.

[0087] The second input mechanism 70 is arranged on the side of the input station A. The second input mechanism 70 is configured to synchronously convey at least two cells to be printed onto the cell printing table 10 located at the input station A.

[0088] The second printing mechanism is arranged above the second printing station B. The second printing mechanism is configured to synchronously print at least two cells on the cell printing table 10 rotated to the printing station.

[0089] The second output mechanism 80 is arranged on the side of the output station C. The second output mechanism 80 is configured to receive at least two printed cells on the cell printing table 10 rotated to the output station C and output at least two printed cells.

[0090] It can be seen that through the cooperation of the rotating platform 60, the second input mechanism 70, the solar cell printing table 10, the second printing mechanism and the second output mechanism 80, the solar cell printing device provided by the embodiment of the present application realizes the synchronous printing of more than two solar cells, and realizes the automatic loading and unloading of solar cells, thereby improving the printing efficiency of solar cells. In particular, since the solar cell printing table is arranged on the rotating platform, and the rotating platform drives the solar cell printing table to rotate and switch between the input station, the second printing station and the output station, the size of the device can be reduced.

[0091] In addition, since the solar cell printing table 10 is arranged on the rotating platform 60, and the rotating platform 60 drives the solar cell printing table to rotate and switch between the input station A, the second printing station B and the output station C, the length of the printing device is shortened.

[0092] Optionally, a roll paper conveying mechanism is arranged on each printing table of the solar cell printing table 10. When the solar cell printing table 10 rotates to the input station A, the roll paper conveying mechanisms on each printing table are docked with the output end of the second input mechanism 70 to receive the solar cells to be printed conveyed by the second input mechanism 70. When the solar cell printing table 10 rotates to the output station C, the roll paper conveying mechanism is docked with the input end of the second output mechanism 80 to convey the printed solar cells located on the printing table to the second output mechanism 80.

[0093] By arranging a roll paper conveying mechanism on each printing table of the solar cell printing table 10, the position switching of the solar cells between the second input mechanism 70 and the solar cell printing table 10, and between the solar cell printing table 10 and the second output mechanism 80 is realized.

[0094] The above has described the present application in sufficient detail with a certain degree of particularity. Those of ordinary skill in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application.
