DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to examples and specific implementation modes.

[0021] A photovoltaic cell printing double scraper and double ink knife operation system, the structure of which includes a pair of scrapers 1 and a pair of ink knives 2, the improvement is that the two scrapers 1 operate independently, the specific structure and corresponding operation mode are divided into three embodiments for detailed description. Example 1

[0022] like Figure 1 As shown, a photovoltaic cell printing double-scraper and double-ink knife operation system, whose structure includes a pair of scrapers 1 and a pair of ink knives 2, an L-shaped scraper bracket 3 has an adjustable scraper mounting block 10 at both ends of the bottom, and the inner sides of the two adjustable scraper mounting blocks 10 are respectively provided with a scraper 1 adjustably through a scraper fixing knob 5, and the same side of the two scrapers 1 is respectively provided with an ink knife 2, and the two ink knives 2 are penetrated on a pair of connecting rods 7, one end of the connecting rod 7 is fixed to the lower end of the ink knife bracket 4, and the ink knife bracket 4 is fixedly connected to the scraper bracket 3, and one side of the adjustable scraper mounting block 10 is connected to the connecting plate 9, and the connecting plate 9 is connected to the output end of the cylinder 8, and the cylinder 8 is installed on one side of the scraper bracket 3.

[0023] The distance between the two scrapers 1 is adjustable to be compatible with battery cells of different specifications.

[0024] like Figure 2 As shown, during operation, the experimental object is a solar cell with a half-piece design pattern, where S1 and S2 are equal in distance (i.e., S1=S2), S3 and S4 are equal in distance (i.e., S3=S4), S3<S2, the start position of S2 coincides with the end position of S1, the start position of S3 coincides with the start position of S1, and the start position of S4 coincides with the start position of S2. The two scrapers are marked as scraper 1 and scraper 2 in the figure.

[0025] First, if Figure 2 As shown in the above figure, the battery cell is placed on the printing platform. After the equipment is started, the two scrapers move from the preparation position to the printing position, and the ink knife position remains unchanged. Scraper 1 and scraper 2 simultaneously press down to contact the mesh surface, and the mesh is squeezed and deformed, forming a full-surface contact between scraper 1 and scraper 2. The two scrapers start to move and print from left to right simultaneously. Scraper 1 prints from the starting position S1 to the ending position S1, and scraper 2 prints from the starting position S2 to the ending position S2 (the movement direction is not fixed in actual production, and this embodiment only demonstrates printing from left to right), and the movement stroke between the two is consistent, that is, S3=S4.

[0026] Secondly, when scraper 1 moves to the S3 end position and scraper 2 moves to the S4 end position, as Figure 2As shown in the middle figure, scraper 2 has completed the graphics printing in the S4 area, and scraper 1 has completed the graphics printing in the S3 area. Scraper 2 is lifted up at the S4 end position through program control, and scraper 1 remains unchanged and continues to move forward. At this time, when scraper 1 leaves the S3 end position and approaches the S2 start position of scraper 2, scraper 1 and scraper 2 change from surface contact to line contact, avoiding the poor appearance of the graphics printed by scraper 2 being rubbed and squeezed by scraper 1 when approaching.

[0027] Finally, if Figure 2 As shown in the figure below, when scraper 1 runs to the S1 stop position and scraper 2 runs to the S2 stop position, the printing pattern is completed and the screen is separated from the battery cell. Then the ink knife falls back to complete the ink return action, and a printing cycle is completed. This reciprocating motion completes this action to achieve continuous printing. Example 2

[0028] like Figure 3 As shown, a photovoltaic cell printing double-scraper and double-ink knife operation system, whose structure includes a pair of scrapers 1 and a pair of ink knives 2, the two scrapers 1 are installed at the opposite inner lower ends of a pair of adjacent scraper brackets 3, a scraper fixing knob 5 is provided between the scraper bracket 3 and the scraper 1, an ink knife 2 is respectively provided on the outer side of the two scrapers 1, the two ink knives 2 are respectively installed at the bottom end of an ink knife bracket 4, and an ink knife fixing knob 6 is provided between the ink knife bracket 4 and the ink knife 2.

[0029] like Figure 4 As shown, during operation, the experimental object is a half-piece solar cell with a design pattern, where S1 and S2 are at the same distance (i.e., S1=S2). The two scrapers are marked as scraper 1 and scraper 2 in the figure.

[0030] First, if Figure 4 As shown in the figure above, the battery cell is placed on the printing platform. After the equipment is started, the two scrapers move down from the preparation position to the printing position, and the ink knife position remains unchanged. Scraper 1 and scraper 2 press down the contact mesh surface simultaneously, and the mesh is squeezed and deformed. Scraper 1 starts printing to the left, and scraper 2 starts printing to the right, that is, the scrapers print from the middle to both sides, respectively from the starting positions S1 and S2 to the ending positions S1 and S2, and the printing strokes of the two are consistent.

[0031] Secondly, if Figure 4 As shown in the middle figure, when scraper 1 and scraper 2 print to the edge of the cell, the printing is completed. Scraper 1 and scraper 2 are then lifted up, and the mesh gradually rebounds and recovers due to the reduced tension of the scraper.

[0032] Finally, when scraper 1 and scraper 2 run to the end position S1 and S2, the scraper immediately returns to the ready position. Figure 4As shown in the figure below, printing is completed. Then the ink knife presses down to return the ink, and the ink knife moves in the opposite direction of the scraper to prepare for the next printing. This cycle can be repeated for continuous printing. Example 3

[0033] like Figure 5 As shown, a photovoltaic cell printing double-scraper and double-ink knife operation system, whose structure includes a pair of scrapers 1 and a pair of ink knives 2, the two ink knives 2 are installed at the opposite inner lower ends of a pair of adjacently arranged ink knife brackets 4, an ink knife fixing knob 6 is provided between the ink knife bracket 4 and the ink knife 2, a scraper 1 is respectively provided on the outer side of the two ink knives 2, the two scrapers 1 are respectively installed at the bottom end of a scraper bracket 3, and a scraper fixing knob 5 is provided between the scraper bracket 3 and the scraper 1.

[0034] like Figure 6 As shown, during operation, the experimental object is a half-piece solar cell with a design pattern, where S1 and S2 are at the same distance (i.e., S1=S2). The two scrapers are marked as scraper 1 and scraper 2 in the figure.

[0035] First, if Figure 6 As shown in the figure above, the battery cell is placed on the printing platform. After the equipment is started, the two scrapers move down from the preparation position to the printing position, and the ink knife position remains unchanged. Scraper 1 and scraper 2 begin to press down on the contact mesh surface, and the mesh is squeezed and deformed. Scraper 1 starts printing to the right, and scraper 2 starts printing to the left, that is, the scrapers print from both sides to the middle, and the printing strokes of the two are consistent.

[0036] Secondly, if Figure 6 As shown in the middle figure, when scraper 1 and scraper 2 print to the middle position of the battery cell, that is, the end position S1 and S2, the printing is completed. Scraper 1 and scraper 2 are then lifted up, and the mesh gradually rebounds and recovers due to the reduced tension of the scraper.

[0037] Finally, if Figure 6 As shown in the figure below, when scraper 1 and scraper 2 run to the end position S1 and S2, the scraper immediately returns to the preparation position and printing is completed. Then the ink knife presses down to return the ink, and the ink knife moves in the opposite direction of the scraper to prepare for the next printing. Continuous printing can be carried out by repeating this cycle.

[0038] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
