Specifically, the end where the material 6 first enters the material guide channel 103 is the head end, and the end where the material 6 finally passes through the material guide channel 103 is the tail end. The adhesive dressing 6 peeled off first is 01, specifically, the anti-sticking paper 603 at the tail end of the first adhesive portion and the second adhesive portion is peeled off to a length of each end, and is bent downward and extended to the bottom of the vehicle body 101 through the material guide channel 103, and then passed through the paper winding channel 104 of the vehicle body 101 to the upper surface of the vehicle body 101 and are respectively wound onto the first paper winding roller 502 and the second paper winding roller 503.

The control system can control the driving member and the vehicle body 101 to move synchronously, so that the first paper roller 502 and the second paper roller 503 are in a rotating state during the movement of the vehicle body 101, so as to continuously reel up the anti-sticking paper 603, so that the first adhesive part and the second adhesive part can be gradually exposed, and the anti-sticking paper 603 is prevented from loosening and affecting the bonding effect between the adhesive dressing 601 and the two sides of the weld.

[0062] It should be noted that a first paper clamp 504 is provided on one side of the second fixed frame 501, and a second paper clamp is provided on the other side of the second fixed frame 501. The first paper clamp 504 includes a first rod member and a second rod member arranged parallel to each other and spaced apart.

[0064] The first pressing member 304 and the second pressing member 305 are symmetrically arranged, and both of them are block-shaped or long-strip-shaped. The first pressing member 304 forms a first notch portion 3041 at the bottom of one end of the second pressing member 305, and the second pressing member 305 forms a second notch portion 3051 at the bottom of one end of the first pressing member 304. An accommodating space is defined between the first notch portion 3041 and the second notch portion 3051, and the cross-section of the accommodating space is trapezoidal, so that the shape of the accommodating space can be adapted to the ceramic liner 602.

[0065] Preferably, a sliding groove is formed on the bottom wall surface of the box structure of the fixed component 301, and a sliding rail 306 is provided on the inner surface of the box structure. The sliding rail 306 extends along the width direction of the vehicle body 101. The number of the sliding rails 306 is at least two. The two sliding rails 306 are respectively provided on the left and right side walls of the fixed component 301 in the state shown in the figure, and a transmission screw 307 is connected between the front and rear side walls of the fixed component 301. The two ends of the transmission screw are respectively slidably connected to the sliding rail 306. The number of the transmission screw 307 is at least two.

A transmission ball adapted to be connected to the transmission screw 307 is provided inside each transmission block 308. When the transmission ball rotates relative to the transmission block 308, the rotational motion is converted into a linear motion of the transmission block 308 relative to the slide rail 306, thereby driving the first pressing member 304 to move toward or away from the second pressing member 305 to adjust the distance between the first pressing member 304 and the second pressing member 305, thereby adjusting the width of the accommodating space, so that the automatic pasting device can adapt to ceramic welding pads of different models and widths.

[0066] Preferably, the number of the first driving devices 302 is at least two, and the number of the second driving devices 303 is also at least two. Correspondingly, each first driving device 302 is connected to at least one first pressing member 304, and each second driving device 303 is connected to at least one second pressing member 305. Each driving device individually drives the corresponding pressing member, so that the pressing members in different columns can form a height difference according to actual conditions. Specifically, the height of the pressing member close to the front of the vehicle can be slightly higher than the height of the pressing member close to the rear of the vehicle, so that when the pressing mechanism 3 presses the ceramic liner 602 and the adhesive dressing 601 to the weld during the movement of the vehicle body 101, they can be pressed and pasted through the front pressing member, and then the pressing and pasting effects are further enhanced through the rear pressing member.

The first detection device 401 and the second detection device 402 are used to identify the edge of the weld. Preferably, the first detection device 401 and the second detection device 402 can be lasers or sensors and are connected to a control system. The control system can specifically be a central control system of the automatic welding equipment. The control system receives the feedback data of the first detection device 401 and the second detection device 402, and calculates and analyzes whether the center line 6021 of the ceramic liner 602 is aligned with the center line of the weld. If not, the moving direction and position of the vehicle body 101 can be adjusted in time according to the analysis results.

[0069] To summarize, when the automatic pasting device provided by the present application is working, it first adjusts the distance between the first pressing member 304 and the second pressing member 305 to match the corresponding ceramic pad 602, and then peels off a section of anti-sticking paper 603, passes it through the material guide channel 103 to the bottom of the vehicle body 101, and passes it upward through the vehicle body 101 through the paper roll channel 104 and is fixed to the first paper roll roller 502 and the second paper roll roller 503, wherein the anti-sticking paper 603 peeled off in advance is the end relatively far away from the material guide channel, and drives the vehicle body 101 to move toward the weld. During the movement of the vehicle body 101, the first detection device 401 and the second detection device 402 continuously detect and identify the weld position and transmit the detection data back to the control system, and the control system analyzes and processes the detection data and sends it to the vehicle body 101 again. A control signal is sent to adjust and correct the moving direction of the vehicle body 101. The head end of the material 6 enters the bottom of the vehicle body 101 through the material guide channel 103 under the action of the winding mechanism 5, and the pressing mechanism 3 is started. Multiple first driving devices 302 and multiple second driving devices 303 respectively drive the corresponding pressing components to extend downward. The first pressing component 304 and the second pressing component 305 press the ceramic liner 602 to the weld, and press the first and second adhesive parts of the peeled anti-sticking paper 603 to the two sides of the weld respectively. As the vehicle body 101 continues to move forward, the first pressing component 304 and the second pressing component 305 press and adhere the adhesive dressing 601 to the two sides of the weld. At the same time, the anti-sticking paper 603 continues to be peeled off and rolled up to the winding mechanism 5 as the vehicle body 101 moves forward.
