Description
Technical Field
[0001] The present invention relates to the field of automobile bottom plate production, and in particular to a gluing device for producing bottom guard plates of new energy vehicles. Background Art
[0002] With the booming development of the new energy vehicle industry, consumers are increasingly demanding vehicle performance, safety, and lightweighting. As a key protective component of the vehicle chassis, the underbody guard of new energy vehicles must not only have sufficient strength and impact resistance to protect chassis components from damage such as road debris and water stains, but also meet lightweight requirements to improve vehicle endurance.
[0003] Currently, underbody panels for new energy vehicles, made by gluing glass fiber PP sheets and steel sheets together, are attracting widespread attention due to their lightweight and high-strength properties. However, during the traditional underbody panel gluing process, bubbles in the glue are difficult to remove. Simply pressing the panels together doesn't allow for a complete removal of these bubbles, which can severely impact bond strength and the overall performance of the underbody panel, reducing product yield. Therefore, addressing this issue is crucial. Summary of the Invention
[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a gluing equipment for the production of underbody guard plates of new energy vehicles. When in use, the equipment effectively improves the gluing efficiency in the underbody production process. In addition, the gluing quality is guaranteed by the use of a pressing and auxiliary bubble removal mechanism.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
[0006] The cam is fixedly connected to the bottom plate of the new energy vehicle by a locking mechanism, and the locking mechanism comprises a lock mechanism, wherein the locking mechanism comprises a ring-shaped groove, a ring-shaped sealing plate which can slide up and down, and a ring-shaped sealing gasket which can slide up and down is arranged in the ring-shaped groove. The upper end of the ring-shaped sealing plate is elastically connected to the inner top of the ring-shaped groove by a plurality of springs, and the lower end of the ring-shaped sealing plate is fixedly connected to a ring-shaped sealing gasket; an auxiliary bubble removal mechanism, which is used to improve the gluing effect.
[0007] Preferably, a plurality of support frames are fixedly connected to the lower end of the base plate, and a plurality of support columns are fixedly connected to the upper end of the base plate.
[0008] Preferably, a right-angle limit strip is fixedly connected to the upper end of the bottom plate, and the plurality of support columns are located on the inner side of the plurality of right-angle limit strips.
[0009] Preferably, the upper end of the lifting cover is symmetrically fixedly connected to two guide rods, and the upper ends of the two guide rods both pass through the transverse plate and are slidably connected to the transverse plate.
[0010] Preferably, the auxiliary bubble removal mechanism includes a mounting plate fixedly connected to the rear side of the horizontal plate, a piston plate that can slide up and down is provided in the mounting plate, a strip groove is opened on the vertical plate, and a rectangular bar is fixedly connected to the rear side of the lifting cover, the rear end of the rectangular bar passes through the strip groove, and the upper end of the rear side of the rectangular bar is fixedly connected to the piston plate through a piston rod.
[0011] Preferably, the inner top space of the piston cylinder is connected to the outside through a one-way port, and the inner top space of the piston cylinder is connected to the interior of the lifting cover through a one-way tube, and the one-way tube is a soft tube.
[0012] Preferably, a second one-way valve is installed inside the one-way port, and a first one-way valve is installed inside the one-way tube. The flow direction of the non-self-locking push switch is one-way discharge from the top of the piston cylinder to the outside world, and the flow direction of the first one-way valve is one-way entry into the piston cylinder from the inside of the lifting cover.
[0013] Preferably, a solenoid valve is installed inside the one-way tube, an L-shaped mounting bar is fixedly connected to the left side of the annular sealing plate, a non-self-locking push-button switch is fixedly connected to the upper end of the vertical part of the L-shaped mounting bar, a support plate is fixedly connected to the left side of the lifting cover, the support plate cooperates with the non-self-locking push-button switch, an alarm is fixedly connected to the upper end of the base plate, and the non-self-locking push-button switch is used to control the alarm, the solenoid valve and the electric heating ring.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Four right-angle limit strips are used to position the four corners of the plywood to ensure the accurate position of each layer of material. The support columns ensure that there is a gap between the board and the bottom plate after gluing, which is convenient for subsequent removal, improves operational convenience and material positioning accuracy, and ensures gluing quality and efficiency.
[0016] 2. When the hydraulic telescopic rod drives the lifting cover to move, the two guide rods slide on the horizontal plate to provide guidance for the up and down movement of the lifting cover, ensuring that its movement process is more stable and avoids shaking, ensuring that the pressure is evenly applied during the gluing process, and improving the gluing effect.
[0017] 3. After the annular sealing plate contacts the bottom plate, during the downward movement of the lifting cover, the spring is compressed to make the annular sealing gasket fit tightly against the bottom plate, forming a relatively sealed space, reducing heat dissipation, improving the subsequent glue curing efficiency, and saving energy and time costs.
[0018] 4. The piston plate moves downward to reduce the air pressure in the top space of the piston cylinder. After the non-self-locking push switch is triggered, the solenoid valve opens, and part of the gas in the sealed space is extracted to form a negative pressure, which assists in removing bubbles in the glue, further improves the gluing effect, and reduces product defects.
[0019] 5. When the non-self-locking push switch is triggered, the control alarm will sound a prompt to remind the operator to avoid starting the hydraulic telescopic rod to continue extending, prevent excessive pressure from being applied, ensure operational safety and normal operation of the equipment, and reduce the risk of damage caused by improper operation.

The upper end of the bottom plate 1 is fixedly connected to a right-angle limit strip 8, specifically four right-angle limit strips 8, corresponding to the four corners of the plywood body to be glued, and the plurality of support columns 9 are located on the inner sides of the plurality of right-angle limit strips 8. The upper end of the bottom plate 1 is fixedly connected to a vertical plate 3, the upper end of the vertical plate 3 is fixedly connected to a horizontal plate 4, the lower end of the horizontal plate 4 is fixedly connected to a hydraulic telescopic rod 5, the telescopic end of the hydraulic telescopic rod 5 is fixedly connected to a lifting cover 6, the inner top of the lifting cover 6 is fixedly connected to a connecting rod 11, the lower end of the connecting rod 11 is fixedly connected to a pressure plate 12, and the inner wall of the lifting cover 6 is fixedly connected to an electric heating ring 20;
[0029] As an embodiment of the present invention, the upper end of the lifting cover 6 is symmetrically fixedly connected to two guide rods 7. The upper ends of the two guide rods 7 pass through the horizontal plate 4 and are slidably connected to the horizontal plate 4. The guide rods 7 make the up and down movement of the lifting cover 6 more stable.
[0030] As an embodiment of the present invention, it also includes a sealing mechanism, which includes an annular groove 21 provided at the lower end of the lifting cover 6, an annular sealing plate 10 that can slide up and down is provided in the annular groove 21, the upper end of the annular sealing plate 10 is elastically connected to the inner top of the annular groove 21 by multiple springs 22, and the lower end of the annular sealing plate 10 is fixedly connected to an annular sealing gasket 19. The use of the sealing mechanism can ensure that heating is carried out in a relatively sealed environment, reduce heat dissipation, improve the actual glue curing efficiency, and thus improve the overall production efficiency. In addition, during gluing, the sealing mechanism can also ensure that a stable negative pressure is formed inside it, which is convenient for the subsequent operation of the auxiliary bubble removal mechanism.
[0031] As an embodiment of the present invention, an auxiliary bubble removal mechanism is used to improve the gluing effect. The auxiliary bubble removal mechanism includes a mounting plate 13 fixedly connected to the rear side of the horizontal plate 4, a piston plate 26 that can slide up and down is provided in the mounting plate 13, a strip groove 18 is provided on the vertical plate 3, and a rectangular bar 28 is fixedly connected to the rear side of the lifting cover 6. The rear end of the rectangular bar 28 passes through the strip groove 18, and the rear upper end of the rectangular bar 28 is fixedly connected to the piston plate 26 through a piston rod 27. The inner top space of the piston cylinder 14 is connected to the outside world through the one-way port 16, and the inner top space of the piston cylinder 14 is connected to the interior of the lifting cover 6 through a one-way pipe 31. The one-way pipe 31 is a soft pipe. A second one-way valve 17 is installed inside the one-way port 16, and a first one-way valve 15 is installed inside the one-way pipe 31. The flow direction of the non-self-locking press switch 25 is one-way discharge to the outside world from the top of the piston cylinder 14, and the flow direction of the first one-way valve 15 is one-way entry into the piston cylinder 14 from the inside of the lifting cover 6;
[0032] As an embodiment of the present invention, a solenoid valve 29 is installed inside the one-way tube 31, an L-shaped mounting strip 24 is fixedly connected to the left side of the annular sealing plate 10, and a self-locking push-button switch 25 is fixedly connected to the upper end of the vertical part of the L-shaped mounting strip 24. The left side of the lifting cover 6 is fixedly connected to the support plate 23, and the support plate 23 cooperates with the self-locking push-button switch 25. The upper end of the base plate 1 is fixedly connected to an alarm 30, and the self-locking push-button switch 25 is used to control the alarm 30, the solenoid valve 29 and the electric heating ring 20. When the self-locking push-button switch 25 is triggered, it is in a fully pressed state, closing the hydraulic telescopic rod 5, and connecting the piston cylinder 14 to the lifting cover 6. At this time, the inside of the piston cylinder 14 is in a negative pressure state, and part of the gas in the sealed space surrounded by the lifting cover 6, the annular sealing plate 10 and the base plate 1 can be extracted to generate negative pressure, thereby further assisting in removing bubbles in the glue.
[0033] In the present invention, the glass fiber PP board, rubber mold, steel plate and other materials to be glued are placed on the base plate 1 in the order of glass fiber PP board + rubber mold + steel plate + rubber mold + glass fiber PP board, and four right-angle limit strips 8 are used to position the four corners of the plywood body to be glued to ensure that the position of each layer of material is accurate. At this time, the support column 9 is located below the plywood body to be glued, so that there is a certain gap between the board body and the base plate 1 after gluing, which is convenient for subsequent removal.
[0034] Start the hydraulic telescopic rod 5, and the telescopic end of the hydraulic telescopic rod 5 drives the lifting cover 6 to move downward. During the downward movement of the lifting cover 6, the two guide rods 7 slide on the cross plate 4 to ensure that the up and down movement of the lifting cover 6 is more stable;
[0035] As the lifting cover 6 moves downward, the annular sealing plate 10 first contacts the bottom plate 1. As the lifting cover 6 continues to move downward, the annular sealing plate 10 slides upward in the annular groove 21, the spring 22 is compressed, and the annular sealing gasket 19 fits tightly against the bottom plate 1, forming a relatively sealed space between the lifting cover 6, the annular sealing plate 10, and the bottom plate 1, reducing heat dissipation and improving the subsequent glue curing efficiency.
[0036] The lifting cover 6 continues to move downward until the pressure plate 12 contacts the top glass fiber PP board and applies pressure to it, so that the layers of material fit tightly together to achieve gluing;
[0037] When the lifting cover 6 moves down to a certain position, the rectangular bar 28 moves down with the lifting cover 6, driving the piston rod 27 to move down, and then driving the piston plate 26 to move downward in the piston cylinder 14. Since the second one-way valve 17 is installed inside the one-way port 16, and the first one-way valve 15 is installed inside the one-way tube 31, and the one-way tube 31 is a soft tube, when the piston plate 26 moves down, the solenoid valve 29 is in a closed state. Therefore, the downward movement of the piston plate 26 will reduce the air pressure in the top space of the piston cylinder 14.
[0038] As the lifting cover 6 continues to move downward, the support plate 23 contacts and triggers the non-self-locking push switch 25 on the L-shaped mounting strip 24. At this time, the hydraulic telescopic rod 5 stops working, and the pressure plate 12 maintains the current pressure to ensure that each layer of material is in a completely pressed state. During the pressurization process, the electric heating ring 20 is energized and heated, heating the gluing area in the lifting cover 6, promoting the curing of the glue and improving the gluing quality.
[0039] After the non-self-locking push switch 25 is triggered, the control solenoid valve 29 is opened, so that the piston cylinder 14 is connected to the interior of the lifting cover 6. Since the top space in the piston cylinder 14 has formed a negative pressure during the downward movement of the piston plate 26, part of the gas in the sealed space surrounded by the lifting cover 6, the annular sealing plate 10 and the bottom plate 1 can be extracted at this time, so that the sealed space surrounded by the lifting cover 6, the annular sealing plate 10 and the bottom plate 1 forms a negative pressure, which further assists in removing bubbles in the glue and improves the gluing effect;
[0040] When the non-self-locking push switch 25 is triggered, the alarm 30 is also controlled to emit a prompt sound to remind the operator not to start the hydraulic telescopic rod 5 to continue extending, so as to avoid applying excessive pressure. After the gluing is completed, the hydraulic telescopic rod 5 can be started to retract.
