Technical Field

[0002] In the production of gaskets, traditional adhesive application methods suffer from problems such as low efficiency and uneven application when applied manually, and difficulty in adapting simple mechanical adhesive application to multiple specifications and environmental unfriendliness, which affect the quality of gaskets and production efficiency. To address these issues, a gasket surface coating uniform adhesive application device was developed.
[0003] Meanwhile, the patent specification with application number CN222197655U discloses an automatic adhesive application device for bulldozer gaskets, "including a main frame, a robotic arm base at the inner bottom of the main frame, an adhesive application robotic arm on the robotic arm base; a positioning panel on the robotic arm base, the positioning panel being located on one side of the adhesive application robotic arm; multiple positioning holes on the positioning panel, each positioning hole containing a retractable positioning pin, and multiple positioning pins; a start / stop switch for controlling the device to be activated on the main frame. The positioning pins retracting within the positioning holes can form a matching positioning for gaskets of different specifications."
[0004] Existing sealing gasket surface coating and adhesive application devices lack effective fixation of the coating during adhesive application, which can easily lead to coating displacement and wrinkling, affecting the coating quality. Secondly, the bonding process between the coating and the sealing gasket is relatively simple, lacking a secondary pressing process, resulting in insufficient bonding and poor sealing effect.
[0005] Therefore, a device for uniformly applying adhesive to the surface of a sealing gasket is proposed to address the above problems. Utility Model Content

This device effectively prevents the film from shifting or wrinkling during the adhesive application process, ensures uniform adhesive application and flatness of the film, and further improves the adhesion and sealing performance between the film and the sealing gasket, thereby effectively enhancing product quality.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for uniformly applying adhesive to the surface of a sealing gasket, comprising a worktable, a pressing assembly mounted on the top of the worktable, two electric slide rails mounted on the top of the worktable, an adhesive application support platform slidably connected to the outer surfaces of the two electric slide rails, a fixing frame fixedly connected to the top of the worktable, a cylinder mounted on the top of the fixing frame, the output end of the cylinder penetrating the top of the fixing frame and fixedly connected to an adhesive application assembly, the adhesive application assembly including an adhesive application lifting plate, the adhesive application lifting plate and... A fixed frame is slidably connected, and the output end of the cylinder passes through the fixed frame and is fixedly connected to the glue-applying lifting plate. The bottom end of the glue-applying lifting plate is provided with a receiving groove. The inner walls on both sides of the receiving groove are rotatably connected to a bidirectional lead screw. One end of the glue-applying lifting plate is fixedly connected to a power motor.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1 to 6 As shown, this utility model provides a device for uniformly applying adhesive to the surface of a sealing gasket, including a workbench 1, a pressing component 7 installed on the top of the workbench 1, two electric slide rails 2 installed on the top of the workbench 1, an adhesive application support platform 6 slidably connected to the outer surfaces of the two electric slide rails 2, a fixed frame 4 fixedly connected to the top of the workbench 1, a cylinder 3 installed on the top of the fixed frame 4, and the output end of the cylinder 3 passing through the top of the fixed frame 4 and fixedly connected to the adhesive application component 5.
[0031] The adhesive application assembly 5 includes an adhesive application lifting plate 51, which is slidably connected to a fixed frame 4. The output end of a cylinder 3 passes through the fixed frame 4 and is fixedly connected to the adhesive application lifting plate 51. A receiving groove 53 is provided at the bottom of the adhesive application lifting plate 51. A bidirectional lead screw 58 is rotatably connected to the inner walls of both sides of the receiving groove 53. A power motor 55 is fixedly connected to one end of the adhesive application lifting plate 51. The output end of the power motor 55 passes through the adhesive application lifting plate 51 and is fixedly connected to the bidirectional lead screw 58. Moving frames 56 are threaded onto the threads of the bidirectional lead screw 58 at the points where threads are engraved in different directions. A pressure component 54 is provided on one side of the bottom of each of the two moving frames 56, and an adhesive application rod 57 is fixedly connected to the bottom of each of the two moving frames 56. Through the cooperation of the bidirectional lead screw 58 and the power motor 55, the two moving frames 56 can be driven to drive the adhesive application rod 57 to apply adhesive from the middle to both sides, making the adhesive application on the film surface more uniform. The pressure component 54 can press the film during adhesive application to prevent the film from moving and ensure the quality of adhesive application.
[0032] Specifically, an anti-slip pad 61 is fixedly connected to the top of the adhesive application support platform 6. The anti-slip pad 61 can increase the friction between the film and the adhesive application support platform 6, prevent the sealing gasket from sliding during the adhesive application and pressing process, and ensure processing accuracy and product quality.
[0033] like Figures 1 to 6 As shown, the pressing assembly 54 includes two telescopic outer rods 544, which are engaged with the movable frame 56. The inner surfaces of the two telescopic outer rods 544 are slidably connected to telescopic inner rods 541. The top ends of the two telescopic inner rods 541 are fixedly connected to a return spring 546, and the bottom ends of the two telescopic inner rods 541 are fixedly connected to a pressing frame 543. The inner surface of the pressing frame 543 is rotatably connected to a pressing roller 542. The return spring 546 can keep the pressing roller 542 pressing the film tightly, ensuring that the pressing roller 542 applies stable pressure to the film during the glue application process.
[0034] Furthermore, two limiting blocks 547 are fixedly connected to the outer surfaces of the two telescopic inner rods 541, and the inner surfaces of the two telescopic outer rods 544 are provided with limiting grooves 545 that cooperate with the two limiting blocks 547. The limiting blocks 547 cooperate with the limiting grooves 545 to limit the movement range of the telescopic inner rods 541 within the telescopic outer rods 544, prevent the telescopic inner rods 541 from detaching from the telescopic outer rods 544, and ensure the stability and reliability of the pressure component assembly 54 structure.
[0035] like Figures 1 to 6 As shown, the pressing assembly 7 includes a fixed frame 72 fixedly connected to the worktable 1. A cylinder 71 is fixedly connected to the top of the fixed frame 72. The output end of the cylinder 71 passes through the fixed frame 72 and is fixedly connected to a pressing lifting plate 75. The pressing lifting plate 75 is slidably connected to the fixed frame 72. Several vacuum suction cups 74 are embedded at the bottom of the pressing lifting plate 75. The vacuum suction cups 74 can descend and adsorb the sealing gasket under the action of the cylinder 71, realizing precise gripping and positioning of the sealing gasket, ensuring accurate adhesion between the sealing gasket and the coated film after adhesive application, and improving the precision and efficiency of pressing.
[0036] It is worth noting that the pressing assembly 7 also includes a support frame 76 fixedly connected to the worktable 1. Two pressing rollers 77 are rotatably connected to the inner walls on both sides of the support frame 76. Pressing motors 78 are fixedly connected to both ends of the support frame 76. The two pressing motors 78 pass through both ends of the support frame 76 and are fixedly connected to the two pressing rollers 77 respectively. The pressing motors 78 drive the pressing rollers 77 to rotate, which can roll the pasted gasket and the film to further remove the air between them, so that the gasket and the film are tightly bonded, enhancing the sealing effect and product quality.
[0037] like Figures 1 to 6As shown, two slide bars 52 are fixedly connected to both ends of the glue application lifting plate 51 and the pressing lifting plate 75. The inner walls on both sides of the fixing frame 1 4 and the fixing frame 2 72 are provided with slide grooves 73 that cooperate with the two slide bars 52. The slide bars 52 cooperate with the slide grooves 73 to provide guidance and support for the lifting movement of the glue application lifting plate 51 and the pressing lifting plate 75, so that the lifting process of the glue application component 5 and the pressing component 7 is more stable and the accuracy of the glue application and pressing action is guaranteed.
[0038] Among them, cylinder 3, power motor 55, pressing motor 78, electric slide rail 2, and cylinder 71 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.
[0039] Working principle and process: When the device is working, the film is first placed on the glue application support platform 6. The anti-slip pad 61 at the top prevents the film from sliding. The cylinder 3 is started, which drives the glue application lifting plate 51 of the glue application assembly 5 to slide down the slide groove 73 of the fixed frame 4 to a suitable height. The power motor 55 drives the bidirectional lead screw 58 to rotate. Due to the action of the threads in different directions of the bidirectional lead screw 58, the two moving frames 56 drive the glue application rod 57 to apply glue from the middle to both sides synchronously. At the same time, the reset spring 546 of the pressure component assembly 54 pushes the pressure roller 542 to press the film. The telescopic inner rod 541 moves in the telescopic outer rod 544. The limiting block 547 cooperates with the limiting groove 545 to prevent disengagement and ensure the stability of the film during glue application.
[0040] After the adhesive is applied, the electric slide rail 2 moves the adhesive application support platform 6 to below the fixed frame 72. The cylinder 71 drives the pressing lifting plate 75 to descend along the slide groove 73 of the fixed frame 72, while simultaneously driving the sealing gasket adsorbed by the vacuum suction cup 74 to descend, so that the sealing gasket and the coated film are initially bonded. Then, the adhesive application support platform 6 moves to the support frame 76, and the pressing motor 78 drives the pressing roller 77 to rotate. After that, the sealing gasket and the coated film are rolled together to further remove air and enhance the bonding, thus completing the uniform adhesive application and pressing operation on the entire surface of the sealing gasket.
