Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive bonding equipment, and more specifically, it relates to a multi-layer adhesive pressing device for door panels. Background Technology

[0002] In the production and processing of door panels, in order to enhance the structural strength and improve the overall performance of the door panels, it is often necessary to perform multi-layer adhesive bonding. By applying glue between the layers of the door panel and applying pressure, the layers of the door panel are tightly bonded together. With the development of the door panel processing industry, the requirements for the precision, efficiency and automation of the adhesive pressing are getting higher and higher. Traditional door panel adhesive pressing mostly relies on manual or semi-automatic equipment, which has shortcomings in terms of centering adjustment, glue application uniformity and adhesive pressing stability, affecting the processing quality and production efficiency of the door panels.

[0003] The existing technology has the following problems: First, the centering operation of the door panel before pressing glue is mostly done manually or by simple mechanical positioning, which makes it difficult to ensure that the door panel is accurately centered, resulting in the offset of the glue application and pressing position, affecting the glue bonding quality. Second, during the glue application and pressing process, it is difficult to accurately control the amount of glue applied, and the pressing force is uneven, which can easily lead to the glue layer being too thick or too thin, and the door panel not being tightly bonded, thus reducing the finished product qualification rate of the door panel.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a multi-layer door panel pressing device in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-layer adhesive pressing device for door panels, which solves the problems of inaccurate centering before adhesive pressing, difficulty in controlling the amount of adhesive applied, and uneven pressing force.

[0006] The purpose and effect of this utility model's multi-layer adhesive pressing device for door panels are achieved through the following specific technical means:

The output end of the first servo motor passes through the support platform and is fixedly connected to a first screw. A displacement device plate is movably connected to the outer surface of the first screw. A crossbeam plate is fixedly connected to the lower end of the displacement device plate. The output end of the second servo motor passes through the crossbeam plate and is fixedly connected to a second screw. A glue-applying mechanism is threaded onto the outer surface of the second screw. A pressing mechanism is fixedly connected to the upper middle portion of the displacement device plate. Guide cylinders are inserted and fixedly connected around the upper perimeter of the displacement device plate. Two symmetrically spaced limiting grooves are opened in the upper middle portion of the support platform. Limiting blocks are fixedly connected to the upper left and upper right portions of the worktable. A centering mechanism is fixedly connected to the upper wall of the worktable.

[0008] Furthermore, the centering mechanism includes a third servo motor, the output end of which passes through the worktable and is fixedly connected to a turntable. A sliding rod is fixedly connected to the upper center of the turntable. Side rods are movably connected to the top two sides of the sliding rod via rotating shafts. Displacement frames are movably connected to the bottom of the two side rods via rotating shafts. Centering plates are fixedly connected to the upper ends of the two displacement frames. Multiple rubber pads are fixedly connected to the opposite surfaces of the centering plates. The third servo motor is fixedly connected to the upper wall of the worktable.

[0009] Furthermore, the pressing mechanism includes two hydraulic cylinders. The output ends of both hydraulic cylinders penetrate the displacement device plate and are fixedly connected to connecting seats. The lower ends of the two connecting seats are fixedly connected to a pressing plate. Buffer springs are fixedly connected to the four corners of the upper end of the pressing plate. Guide rods are fitted inside each buffer spring. An elastic pad is fixedly connected to the bottom of the pressing plate. A power supply box is fixedly connected to the front of the upper end of the pressing plate. A photoelectric sensor is fixedly connected to the front end of the power supply box. The hydraulic cylinders are symmetrically fixedly connected to the middle of the upper end of the displacement device plate.

[0010] Furthermore, the glue application mechanism includes a displacement plate and an electric push rod. The output end of the electric push rod passes through the displacement plate and is fixedly connected to an insert plate. A glue scraper is fixedly connected to the bottom of the insert plate. Multiple glue application strips are fixedly connected to the bottom of the glue scraper. A glue storage tank is fixedly connected to the middle of the right end of the displacement plate. A delivery pipe is inserted through the front end of the glue storage tank. A control valve is provided on the outer surface of the delivery pipe. The displacement plate is threadedly connected to the outer surface of the second screw.

[0011] Furthermore, the piston rod of the hydraulic cylinder is coaxially connected to the connecting seat via a flange, the pressure plate is a rectangular steel plate and is arranged parallel to the bottom of the displacement equipment plate, the detection end of the photoelectric sensor faces the working surface below the pressure plate, the power box is connected to the hydraulic cylinder and the photoelectric sensor respectively via wires, and the positions of the guide rod and the guide cylinder correspond one-to-one.

[0012] Furthermore, the two side rods are staggered on both sides of the sliding rod, the outer middle of the displacement frame slides left and right in the limiting groove, the bottom of the centering plate is located at the upper left and upper right of the support platform, and multiple rubber pads are arranged at equal intervals along the length of the centering plate.

[0013] Furthermore, the insert plate is internally connected to the scraper plate, and the insert plate is internally connected to the glue storage tank through a delivery pipe. The control valve is an electromagnetic control valve and is electrically connected to the control panel through a wire.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] I. In this utility model, the centering mechanism drives the turntable to rotate via a third servo motor, which in turn drives the sliding rod and side rod to move the displacement frame and centering plate, thereby achieving automatic and precise centering of the door panel. This avoids centering deviations caused by manual adjustment or simple mechanical positioning. At the same time, multiple rubber pads on the opposite surfaces of the centering plate can protect the door panel from being pinched during the centering process, and the sliding of the displacement frame within the limiting groove further ensures the stability of the centering process. This ensures that subsequent glue application and pressing processes can accurately act on the preset position of the door panel, significantly reducing adhesive quality problems caused by positional deviations.

[0016] II. In this utility model, the glue storage tank in the glue application mechanism supplies glue to the insert plate and the scraper plate through the delivery pipe. The electromagnetic control valve is electrically connected to the control panel, which can accurately control the glue delivery amount. In conjunction with the electric push rod, the height of the scraper plate and the movement of the displacement plate on the second screw are adjusted to achieve uniform glue application. During the pressing process, two hydraulic cylinders drive the pressing plate to move down through the connecting seat. The buffer spring and elastic pad can buffer the pressing force. The guide rod and guide cylinder work together to ensure the smooth movement of the pressing plate, so that the pressing force is uniform and stable. This effectively avoids the glue layer being too thick or too thin, and the door panel not being tightly bonded, and significantly improves the qualified rate of the finished door panel.

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] This utility model provides a multi-layer sealing device for door panels, including a workbench 1 and a second servo motor 14.

The output end of the first servo motor 12 passes through the support platform 2 and is fixedly connected to a first screw 13. A displacement device plate 4 is movably connected to the outer surface of the first screw 13. The lower end of the displacement device plate 4... A crossbeam plate 8 is fixedly connected. The output end of the second servo motor 14 passes through the crossbeam plate 8 and is fixedly connected to the second screw 15. The outer surface of the second screw 15 is threaded with a glue-applying mechanism 10. A glue-pressing mechanism 5 is fixedly connected to the upper middle part of the displacement device plate 4. Guide cylinders 16 are inserted and fixedly connected around the upper perimeter of the displacement device plate 4.

After the operator starts the device through the control panel 6 on the right side of the front end of the support platform 2, the first servo motor 12 on the left side of the front end of the support platform 2 starts to work.

Since the outer surface of the first screw 13 is movably connected to the displacement device plate 4, and the displacement device plate 4 can slide along the sliding grooves 3 on the left and right sides of the upper end of the support platform 2, the position is stable.

After the glue-applying is completed, the pressing mechanism 5 in the middle of the upper end of the displacement device plate 4 moves smoothly downward under the guidance of the guide cylinders 16 fixedly connected around it, and performs multi-layer pressing treatment on the glued parts of the door panel to ensure that the glue layer is tightly bonded to the door panel, thus completing the multi-layer pressing operation of the entire door panel.
