Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a tailgate anti-pinch strip bonding tooling. Background Art

[0002] A tailgate pinch bar is a safety device typically installed at the closing edge of a vehicle's tailgate (i.e., trunk door). It provides additional protection when closing, preventing objects or people from being pinched or damaged. These bars typically operate in conjunction with sensors in the power tailgate system. When the sensors detect resistance during closing, they immediately stop the tailgate and may automatically reopen it for safety.

[0003] Anti-pinch strips are typically attached to car tailgates. Due to their complex design, they are typically installed manually. Manual installation is inefficient and requires a certain amount of pressure. This can easily lead to problems such as excessive bonding, insufficient pressure, or even incomplete tightening, especially at sharp corners. Once these problems occur, the adhesive's performance is compromised, resulting in poor durability and easy detachment. Furthermore, these problems are difficult to detect in the next process and can be passed on to the customer, leading to returns, exchanges, and complaints.

[0004] Therefore, it is necessary to provide a tailgate anti-pinch strip bonding tool to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a tailgate anti-pinch strip bonding tool.

[0006] The utility model provides a tailgate anti-pinch strip bonding tool, which includes a frame, a tailgate profiling bracket fixed on the top of the frame, a movable cylinder fixed on both left and right ends of the frame, a movable frame fixed on the piston rod end of the movable cylinder, a plurality of bonding cylinders fixed on the movable frame, an anti-pinch strip profiling plate fixed on the output end of the bonding cylinder, an air hole installed on the anti-pinch strip profiling plate, a vacuum pump for sucking and blowing the air hole installed on the frame, the vacuum pump and the air hole are connected through an air pipe, and a first rotary clamping cylinder is installed on the movable frame.

[0007] Preferably, the frame is symmetrically mounted with a second rotary clamping cylinder at the bottom end of the tailgate contoured bracket.

[0008] Preferably, a mounting plate is fixed on the frame, a linear motor is symmetrically fixed on the top of the mounting plate, a mounting seat is fixed to the output end of the linear motor, a Z-axis clamping cylinder is fixed to one side of the mounting seat, and a contour clamp is fixed to the output end of the Z-axis clamping cylinder.

[0009] Preferably, an anti-slip net is installed at the edge of the frame.

[0010] Preferably, a plurality of height-adjustable support legs are provided at the bottom of the frame.

[0011] Compared with the related art, the present invention has the following beneficial effects:

[0012] The tooling has the functions of precise bonding position, stable and controllable bonding pressure and holding pressure. Through the setting of the first rotary clamping cylinder, the second rotary clamping cylinder and the contoured clamping block, the tailgate will not move during the bonding process, so that the bonding effect is better and the problem of the anti-pinch strip not lasting and falling off after bonding is prevented.

[0019] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0020] Please refer to Figures 1 to 5 A tailgate anti-pinch strip bonding tool comprises a frame 1, a tailgate profiling bracket 2 is fixed to the top of the frame 1, a movable cylinder 3 is fixed to the left and right ends of the frame 1, a movable frame 4 is fixed to the piston rod end of the movable cylinder 3, a plurality of adhesive cylinders 17 are fixed on the movable frame 4, and an anti-pinch strip profiling plate 5 is fixed to the output end of the adhesive cylinder 17;

[0021] Technical difficulties: The bonding surface of the anti-pinch strip is a curved surface, and the curved surface changes greatly, resulting in the inability to bond perpendicularly to the bonding surface during bonding. This requires the anti-pinch strip bonding to be divided into multiple sections, and the bonding force applied on each section is perpendicular to the bonding surface with a force component greater than 15N / CM2. During bonding, the directions of movement of each bonding cylinder 17 are inconsistent. The greater the movement distance, the larger the gap between the anti-pinch strip profiling plates 5 on the two bonding cylinders 17 after the movement, resulting in no bonding pressing force at the gap position, or they may get closer and closer to produce extrusion interference. This requires that the distance before bonding is as close to the tailgate as possible, while avoiding interference. The distance is set to 2mm, and the bonding cylinder 17 is then pushed out for bonding.

[0022] The anti-pinching strip profiling plate 5 is provided with an air hole 6 , the frame 1 is provided with a vacuum pump 7 for sucking and blowing air into the air hole 6 , the vacuum pump 7 is connected to the air hole 6 through an air pipe, and the movable frame 4 is provided with a first rotary clamping cylinder 8 .

[0023] The frame 1 is symmetrically mounted with a second rotary clamping cylinder 9 at the bottom end of the tailgate contour bracket 2 .

[0024] A mounting plate 10 is fixed on the frame 1, a linear motor 11 is symmetrically fixed on the top of the mounting plate 10, a mounting seat 12 is fixed to the output end of the linear motor 11, a Z-axis clamping cylinder 13 is fixed to one side of the mounting seat 12, and a contour clamping block 14 is fixed to the output end of the Z-axis clamping cylinder 13.

[0025] The linear motor 11 drives the mounting base 12 to move horizontally, and the Z-axis clamping cylinder 13 drives the contoured clamping block 14 to move downward to support the inner wall of the tailgate to prevent excessive extrusion and deformation of the tailgate during the bonding process.

[0026] By arranging the first rotary clamping cylinder 8, the second rotary clamping cylinder 9 and the contoured clamping block 14, the tailgate is prevented from moving during the bonding process.

[0027] An anti-slip net 15 is installed at the edge of the frame 1 to play a protective role.

[0028] The bottom of the frame 1 is provided with a plurality of height-adjustable support legs 16 to facilitate adjustment of the flatness of the frame 1 .

[0030] S1: manually placing the tailgate onto the tailgate profiling bracket 2 of the tooling, and the tailgate profiling bracket 2 realizes the positioning of the tailgate.

[0031] S2: Manually place the left and right anti-pinch strips, and absorb the anti-pinch strips into the anti-pinch strip profiling plate 5 through the vacuum pump 7.

[0032] S3: The moving frame 4 is driven to move by the moving cylinder 3 so that the anti-pinch strip profiling plate 5 is close to the edge of the tailgate, and the tailgate is clamped and fixed by the first rotating clamping cylinder 8 and the second rotating clamping cylinder 9.

[0033] S4: The linear motor 11 drives the mounting seat 12 and the Z-axis clamping cylinder 13 to move, and the Z-axis clamping cylinder 13 drives the contour clamping block 14 to clamp and support the inner wall of the tailgate.

[0034] S5: The anti-pinch strip profiling plate 5 is driven to move by the bonding cylinder 17 so that the anti-pinch strip is bonded to the tailgate, and the pressure is maintained for 15 seconds to complete the bonding.

[0035] S6: Each cylinder, linear motor and other components move in the opposite direction to restore the tooling.

[0036] S7: Remove the tailgate.
