DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and 5 A new energy battery cell film pasting device in this embodiment includes an operating table 1 and a conveying device 2 installed on the left side of the operating table 1. The top of the operating table 1 is located at the end of the conveying device 2 and is equipped with a guide wheel 306 and a turning table 4. A rotating table 5 and a loading device 7, a film pasting assembly 6 and a unloading device 8 installed around the rotating table 5 are installed on the table top of the operating table 1. The loading device 7 is composed of a screw assembly, a cylinder, a rotating cylinder and an adsorption disk, and the unloading device 8 is composed of a cylinder, a rotating cylinder and an adsorption disk.

[0023] In the above structure, the battery cell is conveyed by the conveying device, and the guide wheel can limit the battery cell to prevent it from falling. Then, the battery cell is adsorbed and flipped in cooperation with the turning table. At the same time, the loading device is running to adsorb and transfer the battery cell to the rotating table for positioning. The rotating table is running and rotating to move the battery cell to the bottom of the film sticking assembly to complete the film sticking operation. After the film sticking is completed, the rotating table is rotated to the unloading device to complete the unloading operation.

[0024] like Figure 2, a belt transmission device 301 and a guide rail 302 are installed on the top of the operating table 1, and two sliders 303 connected to the belt of the belt transmission device 301 are slidably connected to the guide rail 302, one of the sliders 303 is fixedly connected to the upper belt, and the other slider 303 is fixedly connected to the lower belt, and a plurality of protruding ends are formed on the top of the slider 303, passing through the conveying device 2 and extending to the top. When the conveying device conveys the battery core and contacts the guide wheel, the belt transmission device runs, which can drive the two sliders to run in opposite directions, so that the battery core can be clamped in the middle position of the conveying device through the protruding ends, and the guide wheel plays a guiding role, so that the battery core is located at the designated position waiting for flipping and conveying.

[0025] A fixing plate 304 is fixed on the top of the operating table 1, a guide cylinder 305 located between two sliders 303 is installed on the top of the fixing plate 304, and the ejection end of the guide cylinder 305 is connected to a guide wheel 306. The guide cylinder can drive the guide wheel to move, so the battery core can be pushed inward by the guide wheel and clamped at the mating protruding end to complete the correction operation of the battery core.

[0026] like Figure 3 In the direction shown, the flip table 4 includes a plate seat 401 fixed on the top of the operating table 1, a lifting cylinder 402 is installed on the left side of the plate seat 401, a concave plate 403 slidably connected to the plate seat 401 is fixed to the ejection end of the lifting cylinder 402, the left side of the concave plate 403 is installed on the buffer cylinder, a rotating device 404 is installed on the concave plate 403, and an adsorption type flip plate 405 is fixed on the outer side of the rotating shaft of the rotating device 404 located on the inner side of the concave plate 403. After the battery core of the conveying device is calibrated as described above, the rotating device moves the adsorption type flip plate to rotate in an arc, so that the adsorption type flip plate can adsorb the battery core, and then flip it to the side of the rotating table by rotation, waiting for the feeding device to complete the adsorption and conveying of the battery core, and completing the feeding operation.

[0027] like Figure 6 , the table of the rotating table 5 is provided with four notches 501, and a U-shaped plate 502 is fixed at the bottom of the table of the rotating table 5 below the notches 501, and an adsorption station 503 extending into the notches 501 is hinged on the plate surface of the U-shaped plate 502, and an upward push cylinder 504 hinged to the adsorption station 503 is fixed, and the top of the adsorption station 503 is in a convex shape, and the protruding end of the top of the adsorption station 503 extends to the top of the table of the rotating table 5 and forms a gap. The battery core can be adsorbed and positioned by the adsorption station. When the rotating table rotates the battery core to the bottom of the film assembly, because the adsorption station is hinged with the upward push cylinder and the U-shaped plate, when the upward push cylinder is pushed up, it can drive the adsorption station to tilt slightly, and at the same time, the end extending from the protruding end of the adsorption station can play a role in limiting.

[0028] like Figure 4 The film sticking assembly 6 comprises a screw device 601 mounted on the operating table 1, a moving plate 602 is mounted on the moving end of the screw device 601, a push-down cylinder 603 is mounted on the moving plate 602, a support plate 604 slidably connected to the moving plate 602 is fixed to the ejection end of the push-down cylinder 603, and a suction cup 607 is mounted on the support plate 604. The screw device drives the moving plate to move back and forth, so that the suction cup can be located above the film sticking and adsorption station, and then the support plate is driven downward by the push-down cylinder, and the suction cup will also move downward, so that the film taking and pressing operations can be completed, so that the automatic film sticking operation can be completed.

[0029] Among them, an adjusting cylinder 605 is hingedly installed on the support plate 604, and a connecting rod 606 is hinged at the ejection end of the adjusting cylinder 605. The connecting rod 606 is hinged through two rod bodies, one of which is hinged to the adjusting cylinder 605, and the other is hinged to one end of the suction cup 607. One of the rod bodies of the connecting rod 606 is hinged to the suction cup 607 hinged to the bottom of the support plate 604, and a pressure roller 608 is installed on the right side of the suction cup 607. When the suction cup adsorbs the film and is located above the work station, the cylinder is pushed down at the same time to drive the suction cup to attach the film to the battery core. When the adsorption station is slightly tilted, one end of the adsorption station will be lifted up at the same time. With the cooperation of the connecting rod and the support plate, the suction cup is slightly tilted like the adsorption station. At this time, the cylinder is adjusted downward to drive the pressure roller and the suction cup to be close to the battery core through the connecting rod, and then the screw device is reset. During the resetting process, the pressure roller will compact the film again. At the same time, because the adsorption station is lifted up, the firmness of the compaction is improved during the retreat process.

[0030] The working principle of the above embodiment is:

[0031] The battery cell is conveyed by the conveying device until the battery cell contacts the guide wheel. At this time, the belt transmission device and the guide cylinder operate simultaneously. The belt transmission device drives the two slide blocks to slide on the guide rail, thereby moving the battery cell to the center of the conveying device through the protruding end. At the same time, the guide cylinder drives the guide wheel to push the battery cell. In cooperation with the clamping of the protruding end, the battery cell can be corrected so that the battery cell is located in the center of the conveying device. The rotating device then operates to drive the adsorption type flap to adsorb the battery cell, and then drives the adsorption type flap to rotate again so that the battery cell faces upward, waiting for the loading device to operate to adsorb the battery cell and place it on one of the adsorption stations of the rotating table for positioning. The rotating table rotates, driving the battery cell to be located under the film pasting component. Under the operation of the screw device, the moving plate is driven to move, so that the battery cell can be brought The movable suction cup first moves to the top of the film, and completes the material picking operation through the cooperation of the push-down cylinder, and then returns to the top of the battery core. The push-down cylinder also drives the suction cup to fit the adsorbed film to the battery core. At the same time, the push-up cylinder runs to mobilize the adsorption station to adjust the angle, so that the adsorption station is slightly tilted. The fitted suction cup can follow the inclination of the adsorption station under the cooperation of the connecting rod hinge and the supporting plate hinge, and can improve the firmness of the fit through the connecting rod by adjusting the cylinder downward pressure. Then the screw device returns to its position. During the return process, it will drive the pressure roller to press the film tightly on the battery core. At the same time, under the action of the hinge, it can be adjusted with the movement until it moves out of the adsorption station, so that the stability can be improved by pressing the film with the pressure roller. After the bonding is completed, the rotating table rotates to the bottom of the unloading device to complete the unloading operation of the battery core.

[0032] In summary, the film laminating operation of the battery core can be automated, and secondary lamination can be performed at the same time to improve the firmness of the laminating between the film and the battery core. Moreover, under the effect of automation, the laminating position can be improved, and at the same time, the production efficiency can be improved and the labor cost can be reduced.
