Such large batteries are generally heavy and difficult to carry. When the cover sheet is sealed, the batteries are usually evenly placed, the floor area is large, and multiple people are required to complete the work. Therefore, the patent proposes an automatic cover sheet sealing device to solve the problems of large floor area and many people, realize production line automation, and achieve the purpose of cost reduction and efficiency increase. SUMMARY

[0003] To achieve the above purpose, the technical scheme of the application is as follows: an automatic cover sheet sealing device, the device comprising a control system, a rack, a machine head, a sheet feeding mechanism, an automatic track, an induction probe and a negative pressure device, the control system being the software center of the device, controlling the start and stop of the track, the movement of the sheet feeding mechanism and the movement of the machine head.

[0004] Based on the above technical scheme, the rack is the skeleton of the integrated mechanism, which is the hardware carrier for normal operation. The sheet feeding mechanism realizes automatic sheet feeding through a movement device. The sheet feeding mechanism is provided with a sheet placing groove, a tray and a movement device.

The negative pressure device provides negative pressure for the suction cup, and realizes taking, placing and installing of the cover sheet.

[0007] As an improvement of the application, the induction probe is arranged on the inner side of the machine body on both sides of the automatic track.

[0008] Based on the above technical scheme, the induction probe transmits signals to the control system, so that the control system sends instructions to each mechanism. The induction probe is arranged on both sides of the inner side of the machine body.

[0009] As an improvement of the application, the sheet feeding mechanism comprises a sheet placing groove, a tray and a movement device. The sheet feeding mechanism realizes automatic sheet feeding through the movement device.

[0010] Based on the above technical scheme, the face sheet placing groove is used for storing face sheets. The length direction and the width direction thereof can be adjusted, and the face sheet placing groove is suitable for different batteries. The tray supports the face sheet in the face sheet placing groove, and the face sheet is gradually lifted by the moving device.

[0011] As an improvement of the present application, an automatic face sheet sealing method comprises the following steps:

[0012] Step one: the control system controls the movement of the head and performs the actions of taking and installing the face sheet, controls the feeding mechanism to feed the face sheet, and the system instructs the suction cup mold frame of the head to be lowered to make the suction cup contact the face sheet, the negative pressure device is opened to order the face sheet, and the suction cup mold frame is lifted. With the movement of the head to the front of the sealing machine, stop when above the battery, the suction cup mold frame of the head is lowered to install the face sheet on the battery, the negative pressure device is released, the suction cup mold frame is lifted, and with the movement of the head to the rear of the sealing machine, stop above the face sheet placing groove. At the same time, the face sheet in the face sheet placing groove is moved upward under the support of the tray, so that the uppermost face sheet reaches the highest point, facilitating the next time of taking the face sheet;

EMBODIMENT

[0022] The present application will be further illustrated below in conjunction with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the present application and not to limit the scope of the present application.

[0023] Embodiment: refer to Figures 1-3 For one embodiment of the present application, it is helpful to understand the implementation of the present application.

[0024] As Figure 1 shown, the present patent automatic cover sheet device schematic diagram is composed of control system 100, rack 200, head 300, sheet feeding mechanism 400, automatic track 500, and induction probe 600. The control system 100 moves the head 300, controls the sheet feeding mechanism 400 to supply the face sheet, and controls the automatic track 500 to start and stop. The right induction probe 600 senses that the battery enters the equipment working area, sends a signal to the control system 100, and the control system 100 issues an instruction to the sheet feeding mechanism 400 to supply the face sheet, and at the same time issues an instruction to the head 300 to execute the face sheet taking and installation program; the left probe 700 senses that the battery reaches the designated position, sends a signal to the control system 100, uses the automatic track 500 to stop, positions the battery, and then the head 300 executes the face sheet installation instruction.

[0025] The automatic track is provided with right and left induction probes. Assuming that the track movement direction of the device is from right to left, when the product passes the right induction probe, a signal is transmitted to the control system, which issues the following instructions: 1) the instruction starts the servo motor of the sheet feeding mechanism, so that the sheet feeding mechanism moves upward to feed the sheet to a certain position; 2) the instruction starts the servo motor of the head, so that the cylinder on the head moves downward with the suction frame to take the sheet, and then moves upward and forward (towards the track side) driven by the servo motor. When reaching the top of the battery, the cylinder moves downward to install the sheet on the battery, and then moves upward to reset, and the servo motor drives the head to move backward until reaching the top of the sheet placement groove. 3) when the suction frame is pressed on the sheet, the instruction starts the negative pressure device to suck the sheet. When the sheet is installed on the battery, the negative pressure is released. 4) when the battery is transported to a specified position on the automatic track, the left induction probe is triggered to stop the track. After the sheet is installed, the track starts to transport the battery to the next process.

[0026] As shown in Figure 2 , the head 300 is composed of a three-axis movement mechanism 301, a suction frame 302, a suction disc 303 and a negative pressure device 304. After receiving the instruction from the control system 100, the three-axis movement mechanism 301 moves to the first position above the sheet placement groove 403. Then the suction frame 302 moves downward until the suction disc 303 contacts the sheet, and the negative pressure device 304 is turned on to suck the sheet. The suction frame 302 rises with the sheet, and then the head 300 moves to the top of the battery. The suction frame 302 lowers with the sheet, and the sheet is installed with the battery. At this time, the negative pressure device 304 is turned off, the suction frame 302 rises, and the head 300 resets. At the same time, the automatic track 500 starts to transport the product battery out of the device working area.

[0027] As shown in Figure 3 , the sheet feeding mechanism 400 is composed of a movement device 401, a tray 402 and a sheet placement groove 403. The sheet placement groove 403 stores a plurality of sheets. When the uppermost sheet is taken away by the head 300, the movement device 401 starts to move the tray 402 upward with the sheet to a certain distance, so that the uppermost sheet is in a suitable position that can be taken by the head 300. The movement device is driven by a servo motor and receives instructions from the control system to start the rotating lead screw to move the tray upward or downward. The extended part of the tray supports the sheet in the middle of the sheet placement groove. The sheet placement groove is arranged behind the track, and the sheet placement groove limits the left and right and front and back positions of the sheet, so that the sheet can only move upward and downward with the tray. The servo motor controls the movement distance of the tray to achieve the purpose of feeding.

[0028] It should be noted that the above content only illustrates the technical idea of the present application, and cannot limit the protection scope of the present application. For ordinary skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, which fall within the protection scope of the claims of the present application.
