Description

Technical Field

[0001] This utility model relates to the field of automotive interior manufacturing technology, specifically to an adhesive applicator for automotive interior covering. Background Technology

[0002] Car interior upholstery refers to covering some parts of the car's interior, such as the dashboard, door panels, and center console trim, with materials such as genuine leather, imitation leather, and fabric to enhance the sense of luxury and comfort inside the car. This treatment is particularly common in high-end models and can significantly improve the overall quality of the vehicle. The conventional method of covering the car interior surface with a layer of leather is to apply glue to the inner surface of the leather before covering the interior parts to improve the aesthetics and integrity of the car interior.

[0003] In the Chinese patent for an adhesive applicator for automotive interior upholstery (patent number: CN218890769U), the device includes an adhesive supply component, a connecting component, a first adhesive applicator, and a second adhesive applicator. The adhesive supply component includes a storage tank for storing adhesive; the connecting component includes a connecting pipe, one end of which connects to the storage tank; the first and second adhesive applicators, with identical structures, are arranged parallel and adjacent to each other, located below the storage tank. The first adhesive applicator includes a first adjusting member and multiple first adhesive applicators. The distance between adjacent first adhesive applicators is adjusted by the first adjusting member. This device utilizes the first adjusting member to adjust the distance between adjacent first adhesive applicators to avoid areas where leather does not need to be covered, significantly reducing adhesive usage, avoiding waste, and lowering the manufacturing cost of automotive interior upholstery. However, this device cannot effectively position the sides of the upholstery, causing the upholstery to curl or peel during adhesive application, thus affecting the processing quality and efficiency of the adhesive application.

[0004] The purpose of this invention is to provide an adhesive applicator for automotive interior covering panels, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue-applying device for automotive interior covering, comprising a glue-applying table, with brackets fixedly connected to both ends of the upper sidewall of the glue-applying table, and an electric slide rail arranged laterally fixedly connected to the upper ends of the two brackets. A first cylinder is fixedly connected to the moving end of the electric slide rail, and a glue-applying head is fixedly connected to the lower end of the first cylinder. A glue-supplying mechanism for supplying glue to the glue-applying head is fixedly connected to the upper sidewall of the electric slide rail. A spacing adjustment mechanism is fixedly connected to the lower sidewall of the glue-applying table in front of the glue-applying head. The two ends of the spacing adjustment mechanism extend to the top of the glue-applying table and are fixedly connected to two symmetrically arranged second cylinders. An L-shaped plate is fixedly connected to the lower end of each of the two second cylinders. A synchronous motor is fixedly connected to the far side of each of the two L-shaped plates. The main shaft end of the synchronous motor passes through the L-shaped plate and is fixedly connected to a pressure roller.

[0006] As a further embodiment of this utility model: the glue supply mechanism includes a glue storage tank fixed on an electric slide rail, and a glue supply pump is fixedly connected to and communicates with the front side wall of the glue storage tank. The glue outlet of the glue supply pump is connected to the glue application head through a hose.

[0007] As a further embodiment of this utility model: the spacing adjustment mechanism includes a fixed strip shell fixed to the lower side wall of the glue application table. A stepper motor is fixedly connected to the bottom of the fixed strip shell. The main shaft of the stepper motor passes through the fixed strip shell and is fixedly connected to a first bevel gear. A bidirectional lead screw is rotatably connected to the inner wall of the fixed strip shell through a bearing seat. A second bevel gear that meshes with the first bevel gear is fixedly connected to the bidirectional lead screw. Two symmetrically arranged nut blocks are threaded onto the bidirectional lead screw. A set of symmetrically arranged connecting rods is fixedly connected to the far side of each of the two nut blocks. Each set of connecting rods passes through one end of the fixed strip shell and is fixedly connected to a connecting frame. The two connecting frames are arranged opposite each other and their close ends are fixedly connected to a second cylinder.

[0008] As a further embodiment of this utility model, the inner wall of the fixing strip shell is slidably connected to the outer wall of the nut block.

[0009] As a further improvement of this utility model, each end of the fixing strip shell is provided with a set of through holes, and each set of connecting rods is respectively arranged through a set of through holes.

[0010] As a further embodiment of this utility model: the glue applicator includes a cover with an opening facing downwards, a glue applicator roller is rotatably connected to the inner wall of the opening end of the cover, and one side of the glue applicator roller extends to the outer side of the cover.

[0011] As a further embodiment of this utility model: a PLC controller is fixedly connected to the front side wall of the glue application table, and the PLC controller is electrically connected to the electric slide rail, the first cylinder, the glue supply mechanism, the spacing adjustment mechanism, the second cylinder and the synchronous motor respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting two second cylinders, two synchronous motors, and two edge-pressing rollers, activates the two second cylinders to extend and push the two edge-pressing rollers to press the two side corners of the automotive interior covering skin. Then, the two synchronous motors are activated to work synchronously, driving the two edge-pressing rollers to rotate synchronously. This can realize the pressing and conveying of the automotive interior covering skin, preventing curling or edge lifting of the automotive interior covering skin during the glue application process, and ensuring the processing quality and efficiency of glue application.

[0014] 2. This utility model, by setting a spacing adjustment mechanism, starts the stepper motor to drive the first bevel gear to rotate. Since the first bevel gear meshes with the second bevel gear, it can drive the bidirectional lead screw to rotate. At this time, the two nut blocks are displaced in opposite directions, which in turn drives the two sets of connecting rods to displace in opposite directions, and then drives the two pressing rollers to displace in opposite directions to achieve spacing adjustment. The adjustment is convenient and stable, and it can press and position the two sides of the automotive interior covering skin of different widths to facilitate subsequent glue application and improve the applicability.

[0021] Please see Figures 1 to 4 In this embodiment, an adhesive applicator for automotive interior trim includes an applicator table 1. Supports 2 are fixedly connected to both ends of the upper sidewall of the applicator table 1. An electric slide rail 3, arranged laterally, is fixedly connected to the upper ends of the two supports 2. This is existing technology and can drive the applicator head 5 to reciprocate laterally for roller coating of the automotive interior trim, resulting in uniform adhesive application. A first cylinder 4 is fixedly connected to the moving end of the electric slide rail 3, and the applicator head 5 is fixedly connected to the lower end of the first cylinder 4 to control the height of the applicator head 5. An adhesive supply mechanism for supplying adhesive to the applicator head 5 is fixedly connected to the upper sidewall of the electric slide rail 3. A spacing adjustment mechanism is fixedly connected to the lower sidewall of the applicator table 1 in front of the applicator head 5. Both ends of the spacing adjustment mechanism extend above the applicator table 1 and are fixedly connected to two... The system includes two second cylinders 6, each with an L-shaped plate 7 fixedly connected to its lower end. A synchronous motor 8 is fixedly connected to the far side of each L-shaped plate 7. A synchronous frequency converter is added to each synchronous motor 8 to ensure they maintain the same speed. This is existing technology. The main shaft of each synchronous motor 8 passes through the L-shaped plate 7 and is fixedly connected to a pressing roller 9. The second cylinders 6 can control the height of the pressing roller 9 to press the edges of automotive interior trim panels of different thicknesses. During adhesive application, the two synchronous motors 8 are activated to work synchronously, driving the two pressing rollers 9 to rotate synchronously. This enables pressing and conveying of the automotive interior trim panels, preventing curling or edge lifting during adhesive application and ensuring processing quality and efficiency.

[0022] like Figure 4 As shown: The glue supply mechanism includes a glue storage tank 11 fixed on the electric slide rail 3. A glue supply pump 12 is fixedly connected to and communicates with the front side wall of the glue storage tank 11. The glue outlet of the glue supply pump 12 is connected to the glue application head 5 through a hose 13. When applying glue to the automotive interior covering skin, the glue supply pump 12 is started to work, which can draw out the glue in the glue storage tank 11 and introduce it into the glue application head 5 through the hose 13 to apply glue to the automotive interior covering skin. The operation is stable.

[0023] like Figure 2 and Figure 3As shown: The spacing adjustment mechanism includes a fixed strip shell 14 fixed to the lower side wall of the glue application table 1. A stepper motor 15 is fixedly connected to the bottom of the fixed strip shell 14. The spindle end of the stepper motor 15 passes through the fixed strip shell 14 and is fixedly connected to a first bevel gear 16. A bidirectional lead screw 17 is rotatably connected to the inner wall of the fixed strip shell 14 through a bearing seat. A second bevel gear 21 that meshes with the first bevel gear 16 is fixedly connected to the bidirectional lead screw 17. Two symmetrically arranged nut blocks 18 are threaded onto the bidirectional lead screw 17. A set of symmetrically arranged connecting rods 19 is fixedly connected to the far side of the two nut blocks 18. Each set of connecting rods 19 passes through one end of the fixed strip shell 14 and is fixedly connected to a connecting frame 20. The two connecting frames 20 are opposite to each other. The two pressure rollers 9 are fixedly connected to a second cylinder 6 at their respective ends. When the distance between the two pressure rollers 9 needs to be adjusted according to the width of the automotive interior covering, the stepper motor 15 is started, which drives the first bevel gear 16 to rotate. Since the first bevel gear 16 meshes with the second bevel gear 21, it can drive the bidirectional lead screw 17 to rotate. Since the bidirectional lead screw 17 is threadedly connected to two nut blocks 18, the two nut blocks 18 are displaced in opposite directions, which in turn drives the two sets of connecting rods 19 to displace in opposite directions, thereby driving the two pressure rollers 9 to displace in opposite directions to achieve distance adjustment. The adjustment is convenient and stable, and it can press and position the two sides of automotive interior coverings of different widths for subsequent glue application, thus improving the applicability.

[0024] like Figure 3 As shown: The inner wall of the fixed strip shell 14 is slidably connected to the outer wall of the nut block 18, which makes the nut block 18 easy to move and prevents it from rotating axially.

[0025] like Figure 3 As shown: A set of through holes is provided at each end of the fixed strip shell 14, and each set of connecting rods 19 is set through a set of through holes to facilitate the displacement of the connecting rods 19.

[0026] like Figure 4 As shown: The glue applicator 5 includes a cover with the opening facing downwards. A glue applicator roller is rotatably connected to the inner wall of the opening end of the cover. One side of the glue applicator roller extends to the outer side of the cover. Glue can be applied by roller coating, resulting in good glue application effect.

[0027] like Figure 1 As shown: A PLC controller 10 is fixedly connected to the front side wall of the glue application table 1. The PLC controller 10 is electrically connected to the electric slide rail 3, the first cylinder 4, the glue supply mechanism, the spacing adjustment mechanism, the second cylinder 6 and the synchronous motor 8 respectively. It is easy to operate. It means that all electrical equipment of this device is electrically connected to the PLC controller 10. The circuit involved is existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0028] Working principle: When using this device to apply adhesive to the surface of automotive interior parts, firstly, when adjusting the distance between the two pressing rollers 9 according to the width of the automotive interior covering, the stepper motor 15 is started, driving the first bevel gear 16 to rotate. Since the first bevel gear 16 meshes with the second bevel gear 21, it can drive the bidirectional lead screw 17 to rotate. Since the bidirectional lead screw 17 is threadedly connected to two nut blocks 18 respectively, the two nut blocks 18 are displaced in opposite directions, thereby driving the two sets of connecting rods 19 to displace in opposite directions, and thus driving the two pressing rollers 9 to displace in opposite directions to achieve distance adjustment. The adjustment is convenient and stable, and it can press and position the two sides of automotive interior coverings of different widths for subsequent adhesive application, thus improving the applicability.

[0029] Then, the two second cylinders 6 are activated to extend and push the two pressing rollers 9 to press the two side corners of the automotive interior covering skin. Then, the two synchronous motors 8 are activated to work synchronously and drive the two pressing rollers 9 to rotate synchronously. This can realize the pressing and conveying of the automotive interior covering skin, so that the automotive interior covering skin can be prevented from curling or lifting during the glue application process, ensuring the processing quality and efficiency of glue application.

[0030] Then, when the automotive interior trim is delivered directly below the adhesive applicator head 5, the first cylinder 4 is activated to extend, causing the adhesive applicator head 5 to press against the automotive interior trim. The adhesive supply pump 12 is then activated, drawing out the adhesive from the adhesive storage tank 11 and guiding it into the adhesive applicator head 5 through the hose 13. In conjunction with the electric slide rail 3, the adhesive applicator head 5 is driven to reciprocate laterally, performing a roller coating process on the automotive interior trim. The operation is stable and the adhesive is applied evenly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
