Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tooling for bonding automotive roof felt. Background Technology

[0002] The process of bonding felt to the car roof is as follows: First, the car roof is fixed on the fixture, and the felt is placed on the surface of the upper mold. The upper mold uses a suction cup to hold the felt tightly. Then, the upper mold is flipped to fold the felt into contact with the surface of the car roof and press it to complete the bonding operation. However, because the felt itself has a large number of pores, it is difficult for the suction cup and the felt to form a good seal. This requires a strong airflow to achieve effective adsorption, which not only generates a lot of noise but also causes insufficient adsorption stability, affecting the efficiency and quality of operation. Utility Model Content

[0003] To overcome the shortcomings of the large number of pores in the felt itself, which makes it difficult for the suction cup and the felt to form a good seal, requiring a strong airflow to achieve effective adsorption, which not only generates a lot of noise but also causes insufficient adsorption stability, affecting operating efficiency and quality, this utility model provides a tooling for bonding automotive roof felt.

[0004] Technical solution: A tooling for bonding automotive roof felt, comprising a base frame, a robot gripper, an upper mold, and suction cups; the base frame has grooves for preventing the automotive roof from being damaged; the upper mold is rotatably connected to the base frame; the robot gripper is fixedly attached to the upper mold; several suction cups are fixedly attached to the upper mold; it also includes cylinders and support plates; several cylinders are fixedly attached to the front and rear parts of the upper mold respectively; all the telescopic ends of the cylinders on the same side are fixedly attached to a support plate; the two support plates are arranged symmetrically front and rear.

[0005] Furthermore, it is particularly preferred that the surface of the support plate is smooth.

[0006] Furthermore, it is particularly preferred that the upper mold also includes a limiting frame; the limiting frame is fixedly attached to the upper mold.

[0007] In addition, it is particularly preferred that the device also includes telescopic plates; four telescopic plates are fixedly connected to the base frame, and the four telescopic plates are arranged in a rectangular shape; the telescopic end of each telescopic plate is in contact with the limiting frame.

[0008] In addition, it is particularly preferred that it also includes air tubes; several air tubes are fixed to the base frame.

[0009] Furthermore, it is particularly preferred that the upper part of the limiting frame has an angle to facilitate the placement of the felt within the limiting frame.

[0010] The beneficial effects of this utility model are as follows: This utility model fixes the felt by adsorption of the suction cup and support of the support plate, preventing the felt from shifting during transfer and affecting the bonding effect; the support plate assists in fixing the felt on the basis of suction cup adsorption, thereby reducing the required airflow intensity, effectively reducing noise generation, and improving the stability and operational safety of the felt fixation; in addition, during the rotation of the felt, an external air pump connected to the air pipe can be controlled to introduce high-temperature gas between the limiting frame and the felt, thereby heating the felt. The felt (especially those containing synthetic fibers or high-density materials) is relatively hard and brittle at room temperature, but after heating, the fibers soften (glass transition temperature effect), making it easier to conform to the curved surface of the car roof.

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] Example: A tooling for bonding automotive roof mat felt, such as Figures 1-6As shown, it includes a base frame 1, a robot gripper 2, an upper mold 3, and suction cups 4; the base frame 1 has a groove for preventing the car from going over the roof; the upper mold 3 is rotatably connected to the base frame 1; the robot gripper 2 is welded to the upper mold 3; and six suction cups 4 are fixedly attached to the upper mold 3.

[0020] It also includes cylinders 5 and support plates 6; two cylinders 5 are fixedly connected to the front and rear parts of the upper mold 3 respectively; all the telescopic ends of the cylinders 5 on the same side are fixedly connected to a support plate 6; the two support plates 6 are arranged symmetrically front and back.

[0021] To reduce friction with the felt and avoid damaging it, the surface of the support plate 6 is made smooth.

[0022] It also includes a limiting frame 7; the limiting frame 7 is welded onto the upper mold 3.

[0023] It also includes telescopic plates 8; four telescopic plates 8 are fixedly connected to the base frame 1, and the four telescopic plates 8 are arranged in a rectangular shape; the telescopic end of each telescopic plate 8 is in contact with the limiting frame 7.

[0024] It also includes an air tube 9; four air tubes 9 are fixedly connected to the base frame 1.

[0025] To facilitate the placement of the felt inside the limiting frame 7, the upper part of the limiting frame 7 has an angled opening.

[0026] by Figure 1 Based on the viewing angle, the side where the robot's gripper hook 2 is located is the front side, and the side where the base frame 1 is located is the rear side.

[0027] Before use, connect the suction cup 4 and air pipe 9 to the external air pump. During use, place the car roof in the groove on the left side of the base frame 1. Then, manually or using a coating machine, apply glue to the car roof. Next, place the felt on the upper mold 3. Then, start the external air pump connected to the suction cup 4, causing the suction cup 4 to sharply adhere to the felt. Simultaneously, control the cylinder 5 to move the support plate 6, causing the two support plates 6 to move towards each other until they reach the upper surface of the felt. Then, using a front-to-back view as a reference, the robot, through the robot gripper 2, rotates the upper mold 3 and its connected components clockwise, including the felt, so that the felt rotates clockwise until it contacts the upper surface of the car roof. The upper mold 3 then presses and adheres the felt tightly to the car roof. Figure 2 As shown; it should be noted that when the felt is about to contact the top, the control cylinder 5 drives the support plate 6 to move and reset, thereby avoiding affecting the contact between the felt and the top; during the rotation, the felt is fixed by the suction cup 4 and the support plate 6, preventing the felt from shifting during transfer and affecting the bonding effect; the support plate 6 further fixes the felt on the basis of the suction cup 4, thereby reducing the required airflow intensity, effectively reducing noise generation, and improving the stability of the felt fixation and the safety of operation.

[0028] To ensure the relative position of the felt and the car roof remains fixed, thus guaranteeing the bonding effect, a limiting frame 7 is provided on the upper mold 3. During use, the felt is manually placed within the limiting frame 7. When the felt is about to contact the roof, the cylinder 5 is controlled to move and reset the support plate 6. At this time, the felt is only attracted by the suction cup 4, and there is a possibility that the felt will detach and fall directly onto the car roof. To prevent the felt from shifting from the bonding position after falling and affecting the bonding effect, a telescopic plate 8 is provided on the limiting frame 7. When the two support plates 6 move towards each other and reach the upper surface of the felt, the two support plates 6 contact the telescopic ends of the telescopic plate 8, restricting the telescopic ends. After the cylinder 5 moves and resets the support plates 6, the telescopic ends of the telescopic plates 8 descend and contact the car roof under their own weight. The telescopic ends of the four telescopic plates 8 restrict the felt from moving in the horizontal direction, thus preventing the felt from shifting from the bonding position after falling and affecting the bonding effect.

[0029] In addition, during the rotation of the felt, an external air pump connected to the air pipe 9 can be controlled to introduce high-temperature gas between the limit frame 7 and the felt, thereby heating the felt. The felt (especially those containing synthetic fibers or high-density materials) is relatively hard and brittle at room temperature. After heating, the fibers soften (glass transition temperature effect), making it easier to conform to the curved surface of the roof.

[0030] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
