[0004] However, when this device performs edge wrapping treatment on the car door, it does not have a structure for clamping and fixing the car door. When the car door is edge wrapped, a certain extrusion force will be generated. If the car door is not fixed, the position of the car door will shift, thus affecting the efficiency and effect of edge wrapping. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic car door edge wrapping device to solve the problem that when this device performs edge wrapping treatment on the car door, it does not have a structure for clamping and fixing the car door. When the car door is edge wrapped, a certain extrusion force will be generated. If the car door is not fixed, the position of the car door will shift, thus affecting the efficiency and effect of edge wrapping as mentioned in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solutions: An automatic door edge wrapping device, comprising a base, a support leg fixedly installed at the bottom end of the base; a support frame fixedly installed at the top end of the base; a support plate fixedly installed at the top end of the base; a clamping assembly installed outside the support plate; an electric telescopic rod fixedly installed at the bottom of the support frame; an edge wrapping assembly connected to the output end of the electric telescopic rod. Among them, through the clamping assembly, the door panel to be edge wrapped can be clamped; by driving the electric telescopic rod, the edge wrapping assembly can automatically wrap the edge of the door panel.

[0007] Preferably, the clamping assembly includes a servo motor, a reverse threaded rod, a threaded connector and a clamping plate. The servo motor is fixedly installed outside the support plate, and the output end of the servo motor is fixedly installed with a reverse threaded rod.

[0008] Preferably, the clamping assembly includes a guide rod and a guide block. The guide rod is fixedly installed inside the support plate, and the guide block is slidably connected to the outside of the guide rod, and the guide block is fixedly installed outside the clamping plate.

[0009] Preferably, the edge wrapping assembly includes an edge wrapping frame and an edge wrapping groove. The edge wrapping frame is fixedly installed at the output end of the electric telescopic rod, and an edge wrapping groove is formed inside the edge wrapping frame.

[0010] Preferably, the edge wrapping assembly further includes a concentric shaft, an adjusting rod and a pressing wheel. The concentric shaft is rotatably connected inside the edge wrapping groove, an adjusting rod is fixedly installed outside the concentric shaft, and a pressing wheel is rotatably connected to the end of the adjusting rod.

[0011] Preferably, two groups of the pressing wheels are symmetrically arranged up and down with respect to the midpoint of the edge wrapping groove.

[0012] Preferably, the edge wrapping assembly further includes a telescopic spring, and the two ends of the telescopic spring are respectively connected to the inner wall of the edge wrapping groove and the outside of the adjusting rod.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the automatic door edge wrapping device is provided with:

[0014] 1. When the clamping structure of the utility model needs to perform edge wrapping treatment on the door, first place the bottom of the door between the two clamping plates, and then run the servo motor. The output end of the servo motor drives the reverse threaded rod to rotate. The rotation of the reverse threaded rod will drive the threaded connectors threadedly connected at both ends to move towards each other. Through the movement of the two threaded connectors towards each other, the front and rear clamping plates will move together to clamp the bottom of the door located in the middle and fix it at the top end of the base, facilitating edge wrapping.

[0015] 2. When the edge wrapping structure of the present utility model needs to perform edge wrapping treatment on the car door, the electric telescopic rod is operated, and the output end of the electric telescopic rod drives the edge wrapping frame to move to the right. When the edge wrapping groove inside the edge wrapping frame contacts the position on the outer frame of the car door that needs edge wrapping, the edge wrapping knife block inside the edge wrapping groove will cause the plate at the edge of the outer frame of the car door to be folded. As the edge wrapping frame continues to move to the right, the pressing wheels at the tail of the edge wrapping groove will contact the upper and lower ends of the car door plate. As the edge wrapping frame continues to move, the car door plate will push up the upper and lower groups of pressing wheels, causing them to rotate through the concentric shaft and compress the telescopic spring. At the same time, the telescopic spring will generate a reaction force on the adjusting rod, so that the pressing wheels at the tails of the upper and lower groups of adjusting rods roll towards the midpoint of the plate. Through the rolling of the upper and lower groups of pressing wheels, precise positioning and pressing of the plate are carried out to ensure the dimensional accuracy and appearance quality of the edge wrapping.
