Description

Technical Field

[0001] This utility model relates to the technical field of door panel processing equipment, and more specifically, to a glue application device for pretreatment of door panel membrane pressing. Background Technology

[0002] In the door panel manufacturing process, membrane pressing is a crucial step in enhancing the door panel's aesthetics and durability. Prior to membrane pressing, applying adhesive to the door panel is a key process. Traditional door panel adhesive application methods have several drawbacks.

[0003] First, manual glue application is inefficient and cannot meet the needs of large-scale production. Manual operation is not only slow, but also makes it difficult to guarantee the uniformity and stability of the glue application. It easily results in too much or too little glue, or uneven application, which directly affects the quality of the door panel after membrane pressing, leading to defects such as bubbles and wrinkles on the door panel surface, reducing the door panel's aesthetics and quality.

[0004] Secondly, while some automated glue-applying equipment improves glue-applying efficiency to some extent, its structural design is unreasonable. For example, the height adjustment of the glue-applying device is not precise enough, making it unable to adapt to the glue-applying needs of door panels of different thicknesses. Moreover, the method of fixing the door panels is simplistic and not secure enough, allowing the door panels to easily shift during the glue-applying process, which also affects the glue-applying effect. Utility Model Content

[0005] The purpose of this invention is to provide a glue-applying device for pre-treatment of door panels before membrane pressing, so as to solve the problems of low glue-applying efficiency, unstable quality and unreasonable equipment structure in existing door panel glue-applying methods, and improve the quality and production efficiency of glue-applying before door panel membrane pressing.

[0006] A glue-applying device for pretreatment of door panel membrane pressing, comprising:

[0007] Glue application platform: The glue application platform is equipped with glue application slide rails and clamping rails. The two glue application slide rails are arranged parallel to each other on the glue application platform. The glue application slide rails are used to install controllable movable glue application devices, so that the glue application devices can move on the glue application platform according to a predetermined trajectory, thereby realizing glue application to different positions of the door panel. The clamping rails are arranged parallel to the glue application slide rails and are located inside the glue application slide rails. They are used to install clamps to clamp and fix the door panel laterally, ensuring that the door panel will not move laterally during the glue application process.

[0008] Glue application device: The glue application device consists of a slide, a support, an electric telescopic rod, and a glue application roller. Each glue application slide rail is equipped with a slide. The lower end of the support is hinged to one end of the slide. The glue application roller is rotatably mounted on the upper part of the two supports. A hinged electric telescopic rod is set at the other end of the slide, and the other end of the electric telescopic rod is hinged to the upper middle part of the support. By extending and retracting the electric telescopic rod, the tilt of the support can be precisely controlled, thereby achieving precise control of the height of the glue application roller to meet the glue application requirements of door panels of different thicknesses.

[0009] Conveyor rail: The conveyor rail is located between two glue-applying slide rails and below the door panel body. The door panel body can be placed on the conveyor rail, which can transport the door panel body outward from the side where the glue-applying slide rail is located, realizing automatic conveying of the door panel before and after glue application and improving production efficiency.

[0010] Further technical solutions:

[0011] A low-position limiter is also installed in the middle of the slide block. The function of the low-position limiter is to limit the minimum tilt angle that the support can reach, prevent the glue roller from falling too low, and avoid affecting the glue coating effect or causing equipment damage due to excessive tilting.

[0012] The slide is also equipped with a vertical limiter, which is close to the support and located on the outside of the support. When the support is vertical, it will be close to the vertical limiter to limit the vertical position of the support and ensure the stability of the glue applicator under specific working conditions.

[0013] The clamping track is equipped with a clamping device that can move along the clamping track under control, thereby achieving lateral clamping and fixing of the door panel body, ensuring that the door panel will not shift laterally during the glue application process, and guaranteeing the accuracy and uniformity of the glue application.

[0014] The conveyor track is higher than the clamping track, and the clamp can lift the door panel body away from the conveyor track to avoid interference with the conveyor track when clamping and fixing the door panel. It also facilitates subsequent operations such as positioning and gluing the door panel.

[0015] The clamp has an L-shaped structure, consisting of a vertical plate and a horizontal plate. One end of the horizontal plate is connected to the lower end of the vertical plate, and the other end of the horizontal plate has a downward sloping surface. Through this sloping surface, the horizontal plate can be smoothly inserted from the bottom of the door panel body and raise the door panel body. This design makes the clamping operation more convenient and efficient.

[0016] The glue-applying platform has a glue trough at one end, located between glue-applying slide rails. The glue trough can be raised and lowered. When the glue trough rises, it can apply glue to the glue-applying roller, ensuring that the glue-applying roller always has a sufficient supply of glue, so as to achieve continuous and stable glue-applying work.

[0017] Beneficial effects:

[0018] 1. By setting an electric telescopic rod to control the height of the glue application roller, it can accurately adapt to the glue application of door panels of different thicknesses, which greatly improves the adaptability and accuracy of glue application and effectively ensures the glue application quality;

[0019] 2. A movable clamp is used to clamp and fix the door panel laterally on the clamping track. Combined with the fact that the conveying track is higher than the clamping track and the unique L-shaped clamp design, it not only prevents the clamping operation from interfering with the conveying track, but also firmly fixes the door panel, ensuring that the door panel does not shift during the glue application process, and further ensuring the accuracy and uniformity of the glue application.

[0020] 3. The adjustable glue tank design allows the glue roller to replenish the glue in a timely manner, achieving continuous and stable glue application and improving glue application efficiency.

[0021] 4. The low-position limiter and the vertical limiter limit the tilt angle and vertical position of the support, respectively, which enhances the stability of equipment operation, reduces the risk of equipment failure, and extends the service life of the equipment.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] like Figures 1-4The adhesive applicator 5 shown is for pre-treatment of door panel membrane pressing, comprising:

[0029] Glue application platform 1: Glue application platform 1 serves as the basic support structure for the entire device. The parallel glue application rails 2 and clamping rails 3 on it have clearly defined functions. The glue application rails 2 provide a movement path for the glue application device 5, allowing it to move precisely according to the glue application requirements of the door panel. For example, for larger door panels, the glue application device 5 can apply glue along the glue application rails 2 to cover various areas of the door panel. The clamping rails 3 are used to install the clamps 6. The clamps 6 move on the clamping rails 3 to achieve lateral clamping and fixing of the door panel body 4. Figure 1 and attached Figure 2 In the middle, two symmetrical clamping rails 3 are set, and each rail is equipped with a clamp 6. When the door panel is placed on the conveying rail 7 and conveyed to the appropriate position, the clamp 6 can move quickly and clamp the door panel to prevent the door panel from swaying laterally during the glue application process and ensure the accuracy of glue application.

[0030] Glue application device 5: The glue application device 5 consists of a slide block 51, a support 52, an electric telescopic rod 53, and a glue application roller 54. The slide block 51 installed on each glue application slide rail 2 provides a connection base for the support 52. The support 52 is hinged to one end of the slide block 51 at its lower end, allowing it to rotate around the hinge point. The glue application roller 54 is installed at the upper part of the two supports 52. When the electric telescopic rod 53 extends or retracts, its hinged structure with the upper part of the support 52 changes the tilt angle of the support 52, thereby causing the glue application roller 54 to change height. For example, when facing a thicker door panel, the operator can extend the electric telescopic rod 53 through the control system, increasing the tilt angle of the support 52 and causing the glue application roller 54 to rotate. The roller 54 is raised to a suitable height to ensure good contact with the door panel surface for gluing. For thinner door panels, the electric telescopic rod 53 is shortened to lower the height of the gluing roller 54. The low-position limiter 55 limits the minimum tilt angle that the support 52 can reach, preventing the gluing roller 54 from descending excessively. If there were no low-position limiter 55, the gluing roller 54 might descend excessively and hit the door panel or damage itself in the event of a control error of the electric telescopic rod 53, affecting the gluing effect and equipment life. The vertical limiter 56 limits the support 52 when it is in a vertical state, such as during the equipment start-up or stop phase, to ensure that the gluing device 5 is in a stable initial or final state, improving the stability of equipment operation.

[0031] The coordinated operation of the conveyor track 7 and the clamp 6: The conveyor track 7 is higher than the clamping track 3. This design facilitates the operation of the clamp 6. The door panel is first placed on the conveyor track 7 and conveyed to the glue application position. The clamp 6 has an L-shaped structure. The downward inclined surface at the end of its horizontal plate 62 can be smoothly inserted from the underside of the door panel body 4. Then the door panel is lifted and removed from the conveyor track 7. The vertical plate 61 applies lateral clamping force. This design avoids interference between the clamping operation and the conveyor track 7. Moreover, the L-shaped structure makes the clamping action more convenient and efficient. In actual operation, after the door panel is conveyed to the position, the clamp 6 moves along the clamping track 3 to the bottom of the door panel, inserts through the inclined surface and lifts the door panel, and then performs horizontal clamping and fixing to prepare for glue application.

[0032] The working process of the glue tank 8: The glue tank 8, located at the end of the glue application platform 1 between two glue application slide rails 2, adopts a liftable structure, such as a lifting seat 9. When the glue application roller 54 has insufficient glue, the control system issues a command, and the glue tank 8 rises to contact the glue application roller 54 for glue application. During the glue application process, in order to ensure that the glue in the glue tank 8 can be evenly adhered to the surface of the glue application roller 54, a slow-speed motor can be set to drive the glue application roller 54 to rotate to achieve uniform glue application. For example, during continuous glue application, after each or two glue applications are completed, the glue application roller 54 moves to the glue tank 8, and the glue tank 8 automatically rises to replenish the glue application roller 54, avoiding uneven glue application due to insufficient glue. After the glue application work is completed, the glue tank 8 descends to facilitate cleaning and maintenance of the glue tank 8 and prevent glue residue from drying and affecting the next use.

[0033] In actual production scenarios, this device can be combined with other door panel processing equipment to form an automated production line. First, the door panel is conveyed to the gluing position by the conveyor rail 7. The clamp 6 quickly fixes the door panel. The gluing device 5 adjusts the height of the gluing roller 54 according to the thickness of the door panel and then starts the gluing operation. During the gluing process, the glue tank 8 rises in time to replenish the amount of glue for the gluing roller 54. After the gluing is completed, the clamp 6 is released, and the door panel is sent out by the conveyor rail 7 to the outer rail 10 and then enters the next processing step. The whole process is highly automated, which greatly improves production efficiency and product quality.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
