Description

Technical Field

[0001] The utility model relates to the field of automobile power battery equipment, in particular to a sealing nail mounting device. Background Art

[0002] In the battery cell production line, the importance of the sealing nail nailing device is self-evident. It is not only a key link to ensure the sealing of the battery cell, but also an important factor in improving product quality and production efficiency. First of all, the sealing nail nailing device can effectively prevent electrolyte leakage and internal short circuit, thereby ensuring the safety performance of the battery. This not only protects the safety of consumers, but also greatly reduces the after-sales cost of the enterprise. Secondly, by using a high-precision sealing nail nailing device, the enterprise can significantly improve the quality stability of the battery cell and reduce the defective rate. This not only enhances the market competitiveness of the product, but also wins a good reputation for the enterprise. In addition, an efficient sealing nail nailing device can significantly improve production efficiency, shorten the production cycle, and thus reduce production costs, bringing greater economic benefits to the enterprise.

[0003] The existing sealing nail nailing device mainly relies on a vacuum suction cup to realize the sealing nail picking and placing operation. During the operation, the vacuum suction cup contacts the sealing nail, the vacuum pump generates negative pressure, and the sealing nail is adsorbed on the vacuum suction cup. Then the sealing nail is transported to the specified position. After reaching the target position, the vacuum pump stops generating negative pressure, and the sealing nail falls off the vacuum suction cup.

[0004] However, in actual operation, when the vacuum pump stops generating negative pressure and removes the vacuum suction cup, the sealing pin may be taken away by the vacuum suction cup, which may result in the loss of the sealing pin and affect the subsequent welding process. Summary of the invention

[0005] Aiming at the problem that a sealing nail is taken away when a vacuum suction cup is removed, the utility model provides a sealing nail nailing device which does not take away the sealing nail when the vacuum suction cup is removed.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a sealing nail nailing device, including a mounting plate 1, a cylinder is fixed on the mounting plate 1, the telescopic direction of the cylinder is the vertical direction, a connecting plate is arranged below the cylinder, one end of the connecting plate is fixedly connected to the telescopic end of the cylinder, and a vacuum suction cup is fixed on the other end of the connecting plate. The vacuum suction cup is an accordion type, and the vacuum suction cup can be telescoped in the vertical direction. The connecting plate is controlled to rise and fall by the cylinder, thereby driving the vacuum suction cup to rise and fall synchronously. Since the vacuum suction cup is set to an accordion type, when the vacuum suction cup uses negative pressure to absorb the sealing nail, the vacuum suction cup will shrink in the vertical direction under the action of the adsorption force. When the sealing nail is transported to the designated position, the negative pressure stops being generated. At this time, the vacuum suction cup has a tendency to restore its original length, thereby exerting a pressure on the sealing nail to ensure that the sealing nail will not be taken away when the vacuum suction cup is removed.

[0007] Preferably, a guide rail 1 is arranged outside the mounting plate 1, the length direction of the guide rail 1 is the vertical direction, the connecting plate is mounted on the guide rail 1, and the connecting plate can slide along the guide rail 1. The guide rail 1 can limit the position of the connecting plate to ensure the accuracy of its position, thereby improving the conveying accuracy of the sealing nail.

[0008] Preferably, a throttle valve is provided on the cylinder, and the throttle valve is connected to the air inlet and the air outlet of the cylinder respectively. By controlling the size of the airflow through the throttle valve, the speed of the cylinder extending and retracting can be controlled, and the nail suction efficiency can be improved under the premise of ensuring the stability of nail suction.

[0009] Preferably, a magnetic switch is fixed on the outer wall of the cylinder. The magnetic switch can detect the position of the piston in the cylinder and monitor the state of the cylinder in real time.

[0010] Preferably, a fixing plate is provided on the first mounting plate, the first mounting plate is fixed to one side of the fixing plate, the second mounting plate is fixed to the other side of the fixing plate, and a camera assembly is fixed on the second mounting plate. The camera assembly can monitor the state of the vacuum suction cup in real time and upload data in real time. If any abnormal situation occurs, the entire device will stop working immediately to prevent the loss from expanding.

[0011] Preferably, the camera assembly includes a camera, a slider is fixed on the camera, guide rails 2 are arranged on both sides of the second mounting plate, the length direction of the second guide rail is the vertical direction, the slider is embedded in the second guide rail, and the slider can slide along the second guide rail. The slider slides along the second guide rail to adjust the position of the camera, ensuring that the camera can monitor the vacuum suction cup in real time.

[0012] Preferably, the slider is provided with an adjusting screw hole, the center line of which is in the vertical direction, and an adjusting bolt matched with the adjusting screw hole is installed in the adjusting screw hole. By rotating the adjusting bolt, the sliding of the slider on the guide rail 2 can be controlled, thereby achieving precise adjustment and positioning.

[0013] Preferably, a sealing nail vibrating plate is further included, and the sealing nail vibrating plate is located below the vacuum suction cup. The sealing nail vibrating plate can convey sealing nails to the vacuum suction cup to ensure a stable and continuous supply of sealing nails.

[0014] Preferably, it also includes a longitudinal beam, the longitudinal beam has a horizontal length, the longitudinal beam is located on one side of the sealing nail vibration plate, a cross beam is arranged on the longitudinal beam, one end of the cross beam is mounted on the longitudinal beam, the length of the cross beam is horizontal, and the length of the cross beam is perpendicular to the length of the longitudinal beam, the cross beam can slide along the length of the longitudinal beam, a vertical beam is mounted on the cross beam, the length of the vertical beam is vertical, the vertical beam can slide along the length of the cross beam, a fixing plate is mounted on the vertical beam, and the fixing plate can slide along the length of the vertical beam. The vertical beam can adjust the position of the vacuum suction cup in the vertical direction, while the cross beam and the longitudinal beam can adjust the position of the vacuum suction cup in the horizontal direction, ensuring that the vacuum suction cup can be adjusted to any position in the effective working space.

[0015] Preferably, an auxiliary beam is further included, the auxiliary beam is located on the other side of the sealing nail vibration plate, and the length direction of the auxiliary beam is parallel to the length direction of the longitudinal beam, the other end of the cross beam is installed on the auxiliary beam, and accordion covers are installed at both ends of the auxiliary beam. The auxiliary beam provides stable auxiliary support for the cross beam, and the accordion cover effectively prevents dust from intruding, keeping the equipment clean and running efficiently.

[0016] It can be seen from the above technical solutions that the advantage of the utility model is that the lifting and lowering of the connecting plate is controlled by the cylinder, thereby driving the vacuum suction cup to rise and fall synchronously. Since the vacuum suction cup is set to an accordion type, when the vacuum suction cup uses negative pressure to adsorb the sealing nail, the vacuum suction cup will shrink in the vertical direction under the action of the adsorption force. After the sealing nail is transported to the designated position, the negative pressure stops being generated. At this time, the vacuum suction cup tends to restore its original length, thereby exerting a pressure on the sealing nail to ensure that the sealing nail will not be taken away when the vacuum suction cup is removed. In summary, when the sealing nail is adsorbed, the vacuum suction cup will shrink, and when the sealing nail is put down, the vacuum suction cup will stretch and exert a pressure on the sealing nail, so that the vacuum suction cup will not take away the sealing nail when it is removed.

[0029] The second mounting plate 61 is also included, and the second mounting plate 61 is fixed to the other side of the fixing plate 31 by bolts. The second guide rail 611 is arranged on both sides of the second mounting plate 61, and the length direction of the second guide rail 611 is the vertical direction. In this specific embodiment, the camera assembly 6 specifically adopts the following structure: the camera assembly 6 includes a camera 63, such as Figure 5 As shown, a slider 62 is provided on one side of the camera 63, and the slider 62 is fixedly connected to the camera 63 by bolts.

[0030] In this specific embodiment, the sealing nail vibration disk 5 specifically adopts the following structure: the sealing nail vibration disk 5 includes a vibration disk, and the outer wall of the vibration disk is provided with an upper nail groove, which is communicated with the vibration disk. The sealing nails are stored inside the vibration disk, and the sealing nails that have been distinguished on the front and back sides by vibration are sent into the upper nail groove. An optical fiber sensor is installed at the end of the upper nail groove. When the sealing nail passes through the optical fiber sensor, the optical path of the optical fiber sensor will be blocked, and the data will be fed back to the host computer PLC. The host computer PLC will send a command signal to control the vibration disk to stop vibrating, so as to prevent the subsequent sealing nails from squeezing the sealing nails in front, causing the position of the sealing nails to shift.

[0031] The specific use process of the utility model is as follows: first, the sliding of the cross beam 1 on the longitudinal beam 2 is controlled by the servo motor, and then the position of the vertical beam 3 on the cross beam 1 is adjusted to adjust the vacuum suction cup 731 to be directly above the upper nail groove. Next, the telescopic end of the cylinder 74 is extended, and the connecting plate 72 is lowered accordingly, synchronously driving the vacuum suction cup 731 to drop to above the sealing nail. When the vacuum suction cup 731 contacts the sealing nail, the vacuum pump is controlled to generate negative pressure so that the vacuum suction cup 731 absorbs the sealing nail. Under the action of negative pressure, the vacuum suction cup 731 shrinks in the vertical direction.

[0032] Then, the servo motor is used to control the cross beam 1 to slide on the longitudinal beam 2 again, and the position of the vertical beam 3 is adjusted to move the vacuum suction cup 731 to the top of the battery cell injection port. At this time, the vacuum pump is controlled to eliminate the negative pressure and restore the vacuum suction cup 731 to its original length. Before removing the vacuum suction cup 731, it will apply pressure to the sealing pin to ensure that the sealing pin will not be taken away when the vacuum suction cup 731 is removed.

[0033] The entire process is monitored in real time by cameras 63 to ensure the smooth progress of the operation. Once any abnormal situation is detected, the entire device will stop working immediately to prevent any potential loss or damage.

[0034] It can be seen from the above embodiments that the beneficial effect of the utility model is that the lifting and lowering of the connecting plate is controlled by the cylinder, thereby driving the vacuum suction cup to rise and fall synchronously. Since the vacuum suction cup is set to an accordion type, when the vacuum suction cup uses negative pressure to adsorb the sealing nail, the vacuum suction cup will shrink in the vertical direction under the action of the adsorption force. After the sealing nail is transported to the designated position, the negative pressure stops being generated. At this time, the vacuum suction cup tends to restore its original length, thereby exerting a pressure on the sealing nail to ensure that the sealing nail will not be taken away when the vacuum suction cup is removed. In summary, when the sealing nail is adsorbed, the vacuum suction cup will shrink, and when the sealing nail is put down, the vacuum suction cup will stretch and exert a pressure on the sealing nail, so that the vacuum suction cup will not take away the sealing nail when it is removed.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
