Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, and specifically relates to a discharging and tensioning mechanism integrated with corona and a primer coater. Background Art

[0002] The discharging and tensioning mechanism of the existing primer coater generally includes two side plates arranged oppositely, a support roller and a rubber pressing roller assembly. The support roller is rotatably arranged between the two side plates, and the rubber pressing roller assembly is arranged between the two side plates and on one side of the support roller. The rubber pressing roller assembly is used to press the substrate against the support roller to cut off the tension of the substrate. By cutting off the tension of the substrate, the situation that the substrate wrinkles or breaks during walking can be avoided. The discharging and tensioning mechanism with this structure only plays the role of cutting off the tension of the substrate and cannot play the role of corona treatment on the front side of the substrate.

Since the cutting off of the tension of the substrate and the corona treatment on the front side of the substrate are completed by two mechanisms, the volume of the primer coater is relatively large, occupying a large space and reducing the space utilization rate.

One ends of the plurality of discharge electrodes 33 are all used for connection to a transformer. The transformer can supply high-voltage electricity to the plurality of discharge electrodes 33 respectively, so that the plurality of discharge electrodes 33 can perform high-voltage discharge, thereby realizing corona treatment on the front surface of the substrate 200.

[0045] The rubber pressing roller assembly 40 further includes two adjusting modules arranged opposite to each other front and back. At the right ends of the two side plates 10, which are the ends close to the rubber pressing roller assembly 40, two mounting plates 13 are respectively provided. Each adjusting module corresponds to a rubber pressing swing arm 42, a side plate 10, and a mounting plate 13. The two adjusting modules are respectively inclined upward to the left relative to the two side plates 10 and the two mounting plates 13. The adjusting module includes a screw slide 45 and a wedge block 46 connected to the screw slide 45.

The wedge block inclined surface 461 cooperates with the connecting block inclined surface 4241 of the corresponding rubber pressing swing arm 42. The screw slide 45 is used to drive the wedge block 46 to move in a direction close to or away from the rubber pressing roller 41.

[0046] In this embodiment, a shaft rod 423 is penetrated through the second end of the rubber pressing swing arm 42. As Figure 8 shown, the connecting block 424 is sleeved on the outer periphery of one end of the shaft rod close to the center of the rubber pressing roller 41.

[0047] The screw slide 45 is a conventional structure. As Figure 8 shown, the screw slide 45 includes a base 451, two slide plate connecting plates 452 arranged at both ends of the base 451, a screw 453, and a handwheel 454. The base 451 is arranged inside the corresponding side plate 10 and mounting plate 13 and is inclined upward to the left. The slide plate connecting plate 452 is provided with a through hole. One end of the screw 453 is rotatably arranged in the through hole of one of the slide plate connecting plates 452, and the other end of the screw 453 passes through the through hole of the other slide plate connecting plate 452 and is connected to the handwheel 454.

The threaded hole is in threaded cooperation with the screw 453. The bottom end of the base 451 has a chute, and the length direction of the chute is the same as the length direction of the base 451. The top end of the wedge block 46 is slidably matched with the chute to provide support for the movement of the wedge block 46. A slide bearing is arranged in the through hole of the slide plate connecting plate 452, and the slide bearing is sleeved on the outer periphery of the screw 453 to provide rotational support for the screw 453. By rotating the handwheel 454, the screw 453 can be driven to rotate, and the rotation of the screw 453 can drive the wedge block 46 to move in a direction close to or away from the rubber pressing roller 41.

[0048] By means of the two provided adjusting modules, the connecting block 424 of the rubber pressing swing arm 42, and the two rubber pressing cylinders 44, the pressing force can be adjusted after the base material 200 is pressed against the first corona roller 20 by the rubber pressing roller 41. For example, when it is necessary to increase the pressing force, first rotate the handwheels 454 of the two adjusting modules in the counterclockwise direction, which can drive the corresponding screws 453 to rotate in the counterclockwise direction, and then drive the corresponding wedge blocks 46 to move away from the rubber pressing roller 41. At this time, the wedge block inclined surface 461 will be separated from the corresponding connecting block inclined surface 4241, and then the two rubber pressing cylinders 44 are respectively used to drive the two rubber pressing swing arms 42 to rotate in the counterclockwise direction around the axes of the corresponding connecting shafts 43 until the connecting block inclined surfaces 4241 of the two rubber pressing swing arms 42 are engaged with the wedge block inclined surfaces 461 of the two adjusting modules. During the rotation of the two rubber pressing swing arms 42 respectively, the two rubber pressing swing arms 42 can drive the rubber pressing roller 41 to move towards the first corona roller 20, so that the pressing force is increased. When it is necessary to decrease the pressing force, first rotate the handwheels 454 of the two adjusting modules in the clockwise direction, which can drive the corresponding screws 453 to rotate in the clockwise direction, and then drive the corresponding wedge blocks 46 to move towards the rubber pressing roller 41. Under the action of the engagement between the wedge block inclined surface 461 and the corresponding connecting block inclined surface 4241, the wedge block 46 will squeeze the corresponding connecting block 424 downward at this time, so as to drive the two rubber pressing swing arms 42 to rotate in the clockwise direction around the axes of the corresponding connecting shafts 43 respectively, and then drive the rubber pressing roller 41 to move away from the first corona roller 20, so that the pressing force is decreased.

[0049] In this embodiment, baffles 12 corresponding to the rubber pressing roller assembly 40 are provided at the right ends of the two side plates 10, as Figure 2 and Figure 4 shown.

The back surface of the base material 200 can be corona-treated by the multiple discharge electrodes 33 of the second discharge assembly 60. The rubber pressing roller 41 is driven by two rubber pressing air cylinders 41 to move towards the direction close to the first corona roller 20, so that the base material 200 can be pressed tightly on the first corona roller 20 to cut off the tension of the base material 200.

The tension of the base material 200 can be detected by the tension detection roller 90. The swing roller 103 is driven by two swing roller air cylinders 104 to rotate around the axis of the rotating shaft 101, so that the tension fluctuation of the base material 200 can be absorbed.

In this way, cutting off the tension of the base material 200 and corona-treating the front surface of the base material 200 can be completed on the same mechanism. Thus, there is no need to set up a corona mechanism, the volume of the primer coater is reduced, the floor space is saved, the space utilization rate is improved, and the installation and maintenance difficulty of the primer coater is reduced. Through the arranged second corona roller 50 and several second discharge assemblies 60, the base material 200 can be supported by the second corona roller 50, and the back surface of the base material 200 can be corona-treated by several second discharge assemblies 60.
