[0018] The application will be described in detail below in combination with the drawings and specific embodiments.
[0019] As Figure 1 , Figure 2 and Figure 3The battery blue film printing device of the embodiment mainly consists of a feeding unit 3, a rotating positioning unit 2, a turnover conveying unit 1 and a printing unit 4 arranged on a rack (not shown).
[0020] As Figure 3 The feeding unit 3 mainly consists of a supporting plate 33 and a belt conveying mechanism 32, wherein the belt conveying mechanism 32 is driven by a motor 31. The supporting plate 33 is fixedly connected with two pin columns 331 for positioning the workpiece. The battery 10 is placed on the supporting plate and conveyed to the feeding opening by the belt conveying mechanism 32.
[0021] As Figure 2 The turnover conveying unit 1 mainly consists of a sliding rail 14, a bracket 13 slidingly connected with the sliding rail, and a push plate 12 and a pressing disc 11 connected with the bracket and located on both sides of the sliding rail. The sliding rail 14 is arranged on the rack (not shown). The push plate 12 is used for limiting one side of the quadrilateral battery on one side, and the pressing disc 11 is driven by a cylinder to realize the cooperative clamping operation of the battery. After the clamping operation is completed, the workpiece is conveyed into the printing unit 4 for printing. The pressing disc is driven to rotate by a motor to complete the rotating operation of the battery in the clamped state (the operation is only performed after one side of the workpiece is printed). The motor is a servo motor.
[0022] As Figure 3 , Figure 4 The rotating positioning unit 2 mainly consists of a positioning push rod 21, a feeding push rod 22 and a rotating disc 23 located between the positioning push rod 21 and the feeding push rod 22. The positioning push rod 21 is arranged on the rack (not shown) in a lifting manner. The front end of the positioning push rod 21 is provided with a baffle with rollers at both ends, which is used for limiting the other side of the quadrilateral battery. The positioning push rod 21 is driven by a cylinder 211 to push and arranged on the rack in a lifting manner by a lifting cylinder 213. When the bracket 13 slides along the sliding rail, the lifting cylinder drives the positioning push rod 21 to descend to avoid interference with the battery. When the bracket is located at the feeding opening, the lifting cylinder drives the positioning push rod to ascend to complete the positioning operation of the battery. The rotating disc 23 is rotatably arranged on the rack and used for rotating the battery horizontally to change the printing surface. The feeding push rod 22 is driven by a cylinder 221 to push the battery to the rotating disc through the feeding opening to complete the positioning of the battery after the battery is positioned by the positioning push rod 21. The front end of the feeding push rod 22 is connected with a baffle with rollers at both ends.
[0023] As Figure 1 The printing device of the embodiment mainly consists of a printing machine 43, a curing lamp 41 and a drag chain 42. The printing machine 43 is arranged on the rack in a lifting manner and electrically connected with an industrial computer and a power supply (not shown) through the drag chain 42. The curing lamp 41 is fixed on the printing machine 43 and used for curing the blue film of the battery after printing.
[0024] The operation process of the battery blue film spraying device of the embodiment is as follows:
[0025] The battery 10 is conveyed to the feeding port under the action of the belt conveying mechanism 32, and the battery 10 is moved to the rotary disc 23 and preliminarily positioned under the action of the feeding push rod 22. After the push plate 12 and the pressing disc 11 of the turnover conveying unit 1 position the battery 10 twice, the push plate 12 and the pressing disc 11 clamp the battery 10 and enter the two-round spraying operation.
[0026] First-round spraying operation: the bracket 13 slides along the slide rail 14 to convey the clamped battery 10 to the lower side of the sprayer 43 to complete the A-face spraying of the battery 10. The bracket 13 moves the battery 10 to the lower side of the curing lamp 41 to complete the curing operation of the A-printing face. The push plate 12 and the pressing disc 11 of the turnover conveying unit 1 turn over the battery 10 by 90 degrees and convey the battery 10 to the lower side of the sprayer 43 to print the B-face (at this time, the sprayer adjusts the height adaptively according to the height of the printing face), and then the curing operation is performed. The push plate 12 and the pressing disc 11 turn over the battery 10 by 90 degrees in the same direction in sequence to print the opposite side (A1) of the A-face and the opposite side (B1) of the B-face, and complete the curing operation of the corresponding printing face, respectively, to complete the first-round spraying operation. Figure 5
[0027] Second-round spraying operation: the bracket 13 returns to the position of the rotary disc 23, the push plate 12 and the pressing disc 11 release the clamping state of the workpiece 10, and the workpiece 10 is placed on the rotary disc 23. After the rotary disc 23 rotates horizontally by 90 degrees, the push plate 12 and the pressing disc 11 clamp the workpiece and convey the workpiece to the lower side of the sprayer 43, and the first-round spraying operation is repeated. The push plate 12 and the pressing disc 11 turn over the battery 10 by 90 degrees in the same direction in sequence to print the C-face and the opposite side of the C-face, and complete the curing operation of the corresponding printing face, respectively, to complete the second-round spraying operation.
[0028] The sprayer of the embodiment adopts a two-pass mode. The first time is to print half of the thickness with a resolution of 720DPI, and the workpiece is printed when it returns. The cylinder pulls the nozzle to displace, that is, to offset a hole position in the direction perpendicular to the movement direction, which is equivalent to inserting twice the nozzle hole, so as to achieve a resolution of 1400DPI. In this way, the situation of missing points due to nozzle blockage can be effectively avoided, and defective products can be reduced.
[0029] After the spraying operation, the unloading operation is performed: the unloading port and the feeding port are the same port. After the feeding and printing are completed, the battery is clamped by the bracket and retreated to the feeding port, and the battery is pushed to the supporting plate by the limiting push rod or manually taken out.
[0030] The technical scheme of the utility model is not limited to the above-mentioned embodiments, and any technical scheme obtained by equivalent replacement falls within the scope of protection of the present application.
