[0024] Reference Figure 3 and Figure 5 An electromagnetic cavity 9 is provided in the die cutting box 35 , and a slidable electromagnetic cutter 8 is provided on the electromagnetic cavity 9 , and the electromagnetic cutter 8 abuts against the edge material 7 .

[0025] Reference Figure 1 and Figure 4 A glue box 17 is fixed to the upper end of the lifting plate 16. The left and right ends of the glue box 17 are connected with glue tubes 27. The glue tubes 27 are away from each other and extend downward to be connected with the coating boxes 28 on the left and right sides.

[0026] Reference Figure 4 The two adjacent coating boxes 28 on the left and right are each provided with a pressure sensor 1 at the ends away from each other, and the pressure sensor 1 is located at the lower end of the coating head 29.

[0027] The process of the hemming device for a car roof according to the present invention is as follows:

[0028] Place the top surface of the ceiling 21 on the upper end of the sliding plate 11 with the top surface facing upwards, adjust the center of the ceiling 21 through two left-right symmetrical positioning sliders 15, and limit the left and right movement of the ceiling 21. The left and right lifting motors 12 are powered on at the same time. Under the rotation of the lifting screw 13, the lifting plate 16 threadedly connected with the two lifting screws 13 is controlled to move downward. The power motor 18 is powered on and drives the left and right active screws 19 to rotate, so that the driven screw plates 20 threadedly connected with the front and rear active screws 19 are separated from each other. Under the operation of the lifting motor 12 and the active screw 19, the device The coating box 28 located at the driven screw plate 20 abuts against the inner end surface of the ceiling 21, and the electromagnet 23 works to generate magnetic force, which pushes the connecting block 25 sliding in the sliding groove 24 to move, and the connecting blocks 25 on the left and right sides move away from each other, so that the coating boxes 28 on the left and right sides are completely in abutment with the inner end surface of the ceiling 21. At the same time, according to the contact surface between the coating box 28 and the ceiling 21, the torsion bar 3 overcomes the torsion of the torsion spring 2 and rotates, so that the coating head 29 on the coating box 28 can be in close contact with the inner end surface of the ceiling 21, and the adhesive is coated on the ceiling 21 through the coating head 29.

[0029] When the sliding plate 11 drives the roof 21 to move backward to the lifting platform 36, the electrically controlled torsion spring connected between the lifting platform 36 and the rotating rod 37 works, driving the rotating rod 37 to rotate downward, so that the lifting platform 36 and the pushing block 39 can move downward to the driving gear 32. The pushing block 39 is normally set vertically downward, and the main lifting rod 4 works to control the lifting platform 36 to move downward, so that the lifting platform 36 enters the roof protrusion 30. The electrically controlled torsion spring is de-energized, and the rotating rod 37 flips upward under the action of the torsion spring force, so that the buffer pad 40 abuts against the roof protrusion 30. The buffer pad 40 is buffered, and the electromagnetic transmitter 44 works to control the telescopic rod 42 to move toward the outside of the guide cavity 41 under the magnetic force. The electromagnetic transmitter 44 is used to adjust the distance between the pushing block 39 and the lifting platform 36. Subsequently, the main lifting rod 4 works to control the lifting platform 36 to move upward, and the pushing block 39 abuts against the roof protrusion 30 under the action of the electrically controlled torsion spring, pushing the edging material 7 at the roof protrusion 30 to move upward.

[0030] By operating the transport motor 31, the active rod 33 is controlled to rotate, and the rotation of the two active gears 32 drives the meshing driven rack 34 to move back and forth, thereby causing the sliding plate 11 fixedly connected to the driven rack 34 to move back and forth. By the sliding plate 11 moving back and forth, the ceiling 21 at the upper end of the sliding plate 11 is driven to move back and forth, so that the coating head 29 can apply the adhesive to the sliding plate 11 in the front and back directions. During the coating work, the electromagnet in the fixed block 14 works, attracting the positioning slider 15, so that the left and right positioning sliders 15 are separated from each other, so that the ceiling 21 can move backward, and the transport motor 31 drives the sliding plate 11 to move from front to back. Figure 1 Position, when the coating work is completed, the electromagnet in the fixed block 14 controls the positioning sliders 15 on the left and right sides to move away from each other, and the transport motor 31 drives the sliding plate 11 to continue to move backward to perform the hemming work.

[0031] Driven by the buffer pad 40, the edging material 7 is turned upside down on the roof protrusion 30, and the electromagnetic cutter 8 is driven to move along the electromagnetic cavity 9 by the magnetic force in the electromagnetic cavity 9. At the specified position, the edging material 7 is cut by the electromagnetic cutter 8.

[0032] Via the glue pipe 27, the glue required for coating is provided to the coating box 28.

[0033] When the power motor 18 is powered on and drives the coating boxes 28 on the left and right sides away from each other, the pressure sensors 1 are driven away from each other through connection, so that the pressure sensors 1 are in contact with the left and right ends of the ceiling 21. When the pressure sensors 1 on the left and right sides contact the ceiling 21 to trigger the signal, the power motor 18 is powered off and the electromagnet 23 is controlled to be powered on.
