Description

Technical Field

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

[0002] In the automotive manufacturing industry, the quality and installation effect of automotive interior trim have a crucial impact on the overall comfort, aesthetics, and safety of the vehicle. With the continuous development of the automotive industry and the increasing demands of consumers for automotive quality, the importance of adhesive equipment for automotive interior trim is becoming increasingly prominent.

[0003] In traditional automotive interior trim installation, manual bonding accounts for a large proportion. Workers manually apply adhesive using tools such as glue guns and then attach the trim components to the corresponding locations inside the car. This method has several drawbacks:

[0004] First, manual bonding is inefficient. Since each operation relies on manual labor, it is not only slow but also difficult to achieve large-scale, continuous production. For example, a glue gun disclosed in Chinese Patent Publication No. CN107116010A includes a body, a push rod, a push block, a linkage assembly, a trigger, and a limiting member. A handle extends from the bottom of the body. The push block and the linkage assembly are located within the body. The limiting member is located at the rear end of the body. The push rod passes through the limiting member, the body, and the push block. The linkage assembly includes two links arranged horizontally and at an angle to each other, with one link abutting against the push block. The trigger is pivotally mounted on the body, with one end abutting against a push wheel between the two links. When the trigger is pressed, the push wheel is pushed upwards by the trigger, causing the linkage assembly to push the push block forward, tilting the push block and positioning the push rod, thus moving the push rod forward. Therefore, applying adhesive to car interiors using a glue gun requires multiple trigger pulls, and prolonged use of this technique can easily cause hand discomfort for workers. In today's automotive manufacturing industry, where high production capacity is paramount, manual bonding is clearly unsuitable for the demands of rapid production.

[0005] Secondly, the uniformity of adhesive application by hand is difficult to guarantee. Differences in worker skill and experience can easily lead to uneven adhesive application, with some areas receiving too much and others too little. This affects the adhesion of interior components, potentially causing problems such as peeling or detachment during use, thus reducing the quality and lifespan of the car's interior.

[0006] Furthermore, manual operation easily leads to adhesive waste. Workers find it difficult to control the amount of adhesive used during the application process, often resulting in excessive use, which not only increases production costs but may also pollute the environment. Utility Model Content

[0007] The purpose of this invention is to provide an adhesive device for automotive interiors, which aims to improve the efficiency of manually applying adhesives to automotive interiors and avoid the discomfort caused to workers.

[0008] This utility model is implemented as follows: An adhesive device for automotive interior trim includes a storage cylinder, a top frame on the top of the storage cylinder, a first motor on the top frame, and a pressure applying mechanism on the inner side of the storage cylinder. The pressure applying mechanism includes a sealing plate, a support frame, a screw, and a rotating column. The support frame is positioned above the sealing plate, the screw is mounted above the support frame and threaded through the rotating column, and the rotating column is connected to the top frame via a bearing. The first motor controls the rotation of the rotating column. A support assembly is provided on the side of the storage cylinder, including a liftable support plate and an adjustable application mechanism. The application mechanism is positioned above the support plate and connected to the storage cylinder.

[0009] Preferably, a solenoid valve is provided at the bottom output end of the storage cylinder, a feed hopper is provided at the top of the side wall of the storage cylinder, and a support is provided on the outside of the storage cylinder.

[0010] Preferably, the top frame is detachably mounted on the storage cylinder, and a central tube is fixedly mounted in the middle of the top frame. The rotating column is sleeved on the top of the central tube through a bearing connection, and the screw passes through the central tube.

[0011] Preferably, a protruding post is fixedly provided on the inner side of the storage cylinder, the protruding post is provided along the height direction of the storage cylinder, and grooves are provided on the edges of the sealing plate and the support frame, the protruding post is provided through the grooves, and the sealing plate can be raised to above the inlet of the storage cylinder.

[0012] Preferably, the top surface of the central column of the support frame is provided with a polygonal groove, a polygonal column is fixedly provided at the bottom of the screw, and a pressure sensor is provided below the polygonal column. Both the polygonal column and the pressure sensor are located in the polygonal groove.

[0013] Preferably, the support assembly further includes a base frame and a vertical frame, the vertical frame being configured as a U-shaped structure and installed upside down on the edge of the base frame, and the support plate being parallel and adjustablely positioned above the base frame.

[0014] Preferably, a threaded column and a second motor are provided on the side of the vertical frame. The second motor is located on the side of the bottom frame and can control the rotation of the threaded column. A diagonal brace is provided on the side of the support plate. A sliding plate is provided at the end of both the support plate and the diagonal brace. The sliding plate is sleeved on the vertical section of the vertical frame, and the threaded column is threaded through the diagonal brace.

[0015] Preferably, the coating mechanism includes a horizontal plate, a main pipe, and multiple output pipes. The multiple output pipes are all vertically arranged on the side of the horizontal plate. The main pipe is arranged on the top of the multiple output pipes and is connected to a hose. The hose is connected to the output end of the storage cylinder.

[0016] Preferably, the end of the horizontal plate is provided with an insert groove, and the horizontal section of the vertical frame is provided through the insert groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model includes a storage cylinder with a motor above it, a sealing plate inside the storage cylinder, and a screw above the sealing plate. A rotating column is threaded onto the screw, allowing the screw to be controlled to lift and lower the sealing plate while the motor is running. This applies pressure to the colloid located between the sealing plate and the storage cylinder, forcing the colloid out of the storage cylinder. This provides convenience for applying the colloid to the interior surface of an automobile via an applicator.

[0019] This invention features an application mechanism that stably supports multiple output tubes via a horizontal plate. The output tubes are connected to a storage cylinder via flexible hoses, allowing the colloid from the storage cylinder to flow into the output tubes. Since the horizontal plate can move along the length of the vertical frame, the colloid is applied to a large area of ​​the car interior during the movement of the output tubes, achieving rapid application of the colloid.

[0020] This utility model is set on a tray, and the tray is adjustable and set on the side of the vertical frame. Therefore, after multiple car interiors stacked on the tray are placed on the tray, the tray 21 can be raised and lowered as needed to change the height of the car interiors, thus providing convenience for applying adhesive to the surface of the topmost car interior.

Detailed Implementation

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example

[0031] To change the way adhesives are manually applied to automotive interior surfaces and improve the efficiency of adhesive application, thus facilitating high-efficiency production, this embodiment provides an adhesive application and bonding device for automotive interiors. This device allows for one-time adhesive application to interior surfaces such as headliners, carpets, floor mats, stickers, and protective films. This enables workers to adhere the applied adhesive to the interior surfaces of the car's interior, avoiding the need for workers to repeatedly pull the glue gun trigger and spend a considerable amount of time applying adhesive to the automotive interior surfaces.

[0032] like Figure 1 , Figure 2 , Figure 6As shown, specifically, the adhesive bonding device includes a storage cylinder 1, a pressure applying mechanism 3, and a support assembly 2. The pressure applying mechanism 3 is located at the top of the storage cylinder 1, with its lower end extending into the storage cylinder 1. It stores the adhesive in the space formed by the storage cylinder 1 and the pressure applying mechanism 3. Therefore, under the action of the pressure applying mechanism 3, the adhesive can be controlled to be output from the output end of the storage cylinder 1, facilitating the application of adhesive to automotive interior surfaces. The support assembly 2 includes a liftable support plate 21 and an adjustable application mechanism 23. Multiple automotive interior surfaces can be stacked on the support plate 21, and the height of the automotive interior surfaces can be adjusted by raising and lowering the support plate 21, facilitating the application of adhesive to multiple automotive interior surfaces. The application mechanism 23 is located above the support plate 21 and connected to the storage cylinder 1. By controlling the movement of the application mechanism 23 above the automotive interior surfaces, the adhesive output from the application mechanism 23 can be applied to the surface of the automotive interior surfaces, changing the way adhesive is applied using a glue gun.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, in order to enable the storage of colloids and facilitate their dispensing, a solenoid valve is installed at the bottom output end of the storage cylinder 1. The operation of the solenoid valve controls whether the colloid is dispensed from the storage cylinder 1. A feed hopper 15 is provided at the top of the side wall of the storage cylinder 1. The feed hopper 15 is located on the outside of the storage cylinder 1 and is connected to the bottom of the storage cylinder 1. Therefore, the colloid can be added into the storage cylinder 1 through the feed hopper 15.

[0034] like Figure 3 , Figure 4 As shown, in order to pressurize the colloid located in the storage cylinder 1 through the pressure applying mechanism 3 and output the colloid located in the storage cylinder 1, the storage cylinder 1 includes a cylinder body 11, which is mounted on a bracket 12. A top frame 13 is bolted to the top of the cylinder body 11, and a central tube 16 is fixedly installed in the middle of the top frame 13. A first motor 14 is installed at other positions above the top frame 13. The pressure applying mechanism 3 includes a sealing plate 31, a support frame 32, a screw 37, and a rotating column 38. The support frame 32 is located above the sealing plate 31 to enhance the sealing plate 31's ability to withstand pressure. The screw 37 is installed above the support frame 32 and its threads pass through the rotating column 38. When the rotating column 38 can rotate under the action of external force, it can force the screw 37 to rise and fall, thereby adjusting the position of the sealing plate 31 and providing support for the colloid to be forced to output through the pressure of the sealing plate 31. A pipe body can also be provided communicatingly on the sealing plate 31, and a solenoid valve can be installed on the pipe body.

[0035] like Figure 3 , Figure 5As shown, in order to enable the rotation of the rotating column 38, the lower end of the rotating column 38 is connected to the top of the central tube 16 through a bearing, and the screw 37 is installed through the central tube 16. In addition, the first motor 14 is connected to the rotating column 38. Specifically, the power transmission between the first motor 14 and the rotating column 38 can be achieved through pulleys and belts, sprockets and chains, etc., so that the rotating column 38 can be controlled to rotate under the action of the first motor 14, thereby realizing the slow lifting and lowering of the screw 37 and the sealing plate 31, which provides convenience for controlling the output of colloid.

[0036] like Figure 3 , Figure 4 As shown, to prevent the colloid from leaking out from the gap between the sealing plate 31 and support frame 32 and the storage cylinder 1, a sealing layer can be provided on the contact surface between the sealing plate 31 and support frame 32 and the storage cylinder 1. Additionally, to prevent the screw 37 from rotating with the rotating column 38, a protruding post is fixedly provided on the inner side of the storage cylinder 1. The protruding post is positioned along the height direction of the storage cylinder 1, and its top surface is flush with the top surface of the storage cylinder 1. Grooves 34 are provided on the edges of both the sealing plate 31 and the support frame 32, and the protruding post penetrates through the grooves 34. Therefore, the rotation of the sealing plate 31 can be restricted, the rotation of the screw 37 controlled, and support provided for adjusting the height of the sealing plate 31 by rotating the rotating column 38. Furthermore, to allow the colloid to be added to the storage cylinder 1 through the feeding hopper 15, the sealing plate 31 can be raised above the inlet of the storage cylinder 1, i.e., above the bottom of the feeding hopper 15, so that the colloid can be added into the space formed by the sealing plate 31 and the storage cylinder 1 through the feeding hopper 15.

[0037] like Figure 6 As shown, in order to control the lifting and lowering of the tray 21 holding the car interior trim and adjust its position, the tray assembly 2 also includes a base frame 22 and a vertical frame 24. The vertical frame 24 is configured with a U-shaped structure and is installed upside down on the edge of the base frame 22. A threaded post 26 and a second motor 27 are provided on the side of the vertical frame 24. The second motor 27 is located on the side of the base frame 22 and can control the rotation of the threaded post 26. A diagonal support frame is provided on the side of the tray 21. A sliding plate 25 is provided at the end of both the tray 21 and the diagonal support frame. The sliding plate 25 is sleeved on the vertical section of the vertical frame 24, and the threaded post 26 is threaded through the diagonal support frame. Therefore, under the action of the second motor 27, the rotation of the threaded post 26 can be controlled, thereby controlling the lifting and lowering of the tray 21 and realizing the adjustment of the height of the car interior trim.

[0038] like Figure 7As shown, to quickly apply adhesive to the surface of the car interior, the application mechanism 23 includes a horizontal plate 233, a main pipe 232, and multiple output pipes 234. The multiple output pipes 234 are vertically arranged on the side of the horizontal plate 233. The main pipe 232 is connected to the top of the multiple output pipes 234 and is connected to a flexible hose 231. The flexible hose 231 is connected to the output end of the storage cylinder 1. Therefore, the adhesive from the storage cylinder 1 can be output from the multiple output pipes 234 and applied to different locations on the surface of the car interior, changing the current situation where manually holding a glue gun for time-consuming and laborious adhesive application is required. To enable adhesive application over a larger area of ​​the car interior surface, the end of the horizontal plate 233 is provided with an insert groove 235. The horizontal section of the vertical frame 24 passes through the insert groove 235. Therefore, the operator can push the horizontal plate 233 along the horizontal section of the vertical frame 24, causing the multiple output pipes 234 to move simultaneously above the car interior, completing the application of adhesive over a larger area.

[0039] A control box is installed on the side of the tray 21. The control box contains a controller, circuit breaker, relay, etc. Therefore, the operator can operate the control box to control the device. Example

[0040] like Figure 4 As shown, based on Embodiment 1, in order to achieve a stable connection between the screw 37 and the support frame 32, and to monitor the force exerted by the screw 37 on the support frame 32, a polygonal groove 35 is provided on the top surface of the central column of the support frame 32. A disc and a polygonal column 33 are fixedly installed at the bottom of the screw 37. The polygonal column 33 is inserted into the polygonal groove 35, and the disc is connected to the central column of the support frame 32 by bolts. Therefore, with the cooperation of the polygonal column 33, the polygonal groove 35, and the bolts, the screw 37 is stably installed on the support frame 32. In addition, a pressure sensor 36 is provided below the polygonal column 33. The polygonal column 33 can press against the pressure sensor 36. At the same time, there is a gap between the head of the bolt and the upper side of the disc, thus providing space for the screw 37 to descend relative to the support frame 32. The pressure exerted by the screw 37 on the sealing plate 31 and the support frame 32 can then be obtained through the pressure sensor 36. Because the sealing plate 31 and the support frame 32 rise and fall slowly, the pressure exerted by the sealing plate 31 on the colloid can be approximated.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
