Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0027] See also Figure 1-4 As shown, the present invention is a sheet wrapping machine for battery production, comprising an upper channel composed of two vertical plates A1 with a gap, and a lower channel composed of two vertical plates B2 with a gap, the upper channel is located directly above the lower channel, and a gap 6 for the plate 5 to pass through is formed between the upper channel and the lower channel, and the two vertical plates A1 cooperate to form a rectangular channel A10, and the two vertical plates B2 cooperate to form a rectangular channel B20; based on the above, the upper channel and the lower channel constitute the channel system required by the present invention, and when in use, the separator paper 100 is controlled to pass through the channel system; and in order to facilitate the battery plate 5 For wrapping the separator paper 100, a conveying mechanism 4 for conveying the electrode 5 is provided on both sides of the channel system; and side panels 3 are provided on both sides of the channel system, and the inner walls of the side panels 3 are provided with T-shaped guide rails 30 along their length directions; a fixed block 33, an electric slider A32 and an electric slider B31 are provided on the T-shaped guide rail 30, and the fixed block 33, the electric slider A32 and the electric slider B31 are arranged in sequence from top to bottom in the vertical direction; the fixed block 33, the electric slider A32 and the electric slider B31 are all provided with a clamping module that clamps the edge side of the separator paper 100.
[0028] After the separator paper 100 is drawn out from the unwinding device, it passes through the rectangular channel A10 composed of the vertical plate A1 and the rectangular channel B20 composed of the vertical plate B2 in sequence; and in the initial state, the fixed block 33, the electric slider A32 and the electric slider B31 are as shown in FIG. Figure 4 As shown; the control plate 5 is placed on the conveying mechanism 4 on the left. At this time, under the action of the conveying mechanism 4, the plate 5 is driven to pass through the gap 6 and enter the other conveying mechanism 4. At this time, the end of the plate 5 is against the separator paper 100. As the plate 5 moves, the separator paper 100 is wrapped on both sides of the plate 5 in a "U"-shaped structure.
[0029] In the above, after completing the coating of a plate 5, the electric slider A32 is controlled to move upward one station, and at the same time, the electric slider B31 is controlled to move to the initial position of the electric slider A32, and the clamping module of the electric slider B31 is controlled to clamp on the edge side of the separator paper 100. After the electric slider B31 and the electric slider A32 are controlled to move to the initial position, the clamping module of the electric slider A32 is controlled to clamp on the edge side of the separator paper 100.
[0030] Specifically, the clamping module includes a bidirectional telescopic cylinder 311 , and two output ends of the bidirectional telescopic cylinder 311 are respectively connected to a clamping block 313 through an L-shaped connecting rod 312 , and the inner wall of the clamping block 313 is provided with a rubber clamping layer.
[0031] It can be known that in order to use the separator paper 100 to cover the electrode 5, the separator paper 100 needs to be cut during use, so a cutting mechanism for cutting the separator paper 100 is provided on the upper channel; the cutting mechanism includes a cutting knife 14 that moves along the direction perpendicular to the separator paper 100, an opening 12 for the cutting knife 14 to pass through is provided on a vertical plate A1, and a rectangular groove 13 for avoiding the cutting knife 14 is provided on the inner wall of the other vertical plate A1. When the cutting mechanism is used to cut the separator paper 100, the opening 12 is located between the fixed block 33 and the electric slider A32; and at this time, the clamping modules on the fixed block 33 and the electric slider A32 are synchronously controlled to clamp on the edge side of the separator paper 100.
[0032] At the same time, during use, when the control plate 5 passes through the gap 6, the control electric slider A32 and the electric slider B31 are moved toward each other, that is, the control electric slider A32 and the electric slider B31 are moved toward the side close to the gap 6.
[0033] When using, avoid using the cutting mechanism to cut the separator paper 100 so that the separator paper 100 shakes and the cut is offset. Figure 5-6In the present invention, a rectangular mounting groove 16 is provided on the inner wall of the vertical plate A1 located on at least one side of the opening 12. The inner bottom side of the rectangular mounting groove 16 is connected to a clamping strip 18 through a micro telescopic cylinder 17. When cutting, the micro telescopic cylinder 17 is controlled to extend and drive the clamping strip 18 to clamp on the two side walls of the partition paper 100 respectively; the linkage design of the cutting mechanism and the clamping strip effectively eliminates the material shrinkage during cutting, and the cutting size error is controlled within ±0.3mm.
[0034] In the present invention, a controller is also included, which connects the micro telescopic cylinder 17, the electric slider A32, the electric slider B31, the clamping module, and the driving mechanism for driving the cutting knife 14; the controller is equipped with a synchronous control module for coordinating the electric slider A32 and the electric slider B31 to maintain a constant tension of the separator paper 100 in a differential motion manner.
[0035] Specifically, the driving mechanism of the cutting knife 14 includes a servo motor 141 and a crank slider mechanism 142. The servo motor 141 is connected to the controller via an encoder, and the controller adjusts the crank rotation angle according to the preset cutting length.
[0036] Specifically, a laser displacement sensor is set on the outer side of a vertical plate A1. The detection end of the laser displacement sensor points to the gap 6 and is connected to the controller for real-time monitoring of the insertion depth of the electrode 5; the closed-loop control of the laser displacement sensor and the servo motor ensures that the deviation of the electrode insertion depth is less than 0.5mm.
