Description

Technical Field

[0001] The present invention relates to the technical field of retarder shock absorber plate processing, and particularly relates to a rubber coating device for a retarder shock absorber plate and a working method thereof. Background Art

[0002] A hydraulic retarder is an automotive retarder that reduces the vehicle speed through a hydraulic device. Generally, it consists of components such as a retarder body, a control device, and an electronic control unit. In the structure of the retarder body, a rotor and a stator jointly form a working chamber. When the hydraulic retarder works, the electronic control system controls a proportional valve to apply air pressure to the working fluid to make the oil fill into the working chamber; and the proportional valve is fixed on the hydraulic retarder through a shock absorber plate. Through the elasticity of the rubber, the vehicle can withstand greater bumps during driving, more effectively ensure the safety of the continuous operation of the hydraulic retarder, and can extend the service life of the retarder.

[0003] In the prior art, the rubber on the shock absorber plate and the mounting plate are generally adhered through a glue solution to form a shock absorption structure; due to the small area and complex shape, precise coating is generally carried out by a robotic arm.

[0004] However, the above-mentioned robotic arm coating equipment still has the following defects during use: In actual operation, the problem of uneven thickness often occurs when coating the glue solution. Since it is difficult to precisely control the coating amount each time, multiple repeated coatings are often required to achieve the ideal bonding effect. Such a process not only significantly reduces the production efficiency, but also easily causes unnecessary glue residue in non-target areas (i.e., positions on the side of the rubber that do not need to be bonded). These excess glue residues will harden in subsequent processes, thereby affecting the overall performance of the shock absorber plate. Summary of the Invention

[0005] In order to overcome the above technical problems, the purpose of the present invention is to provide a rubber coating device for a retarder shock absorber plate and a working method thereof, which are used to solve the problems in the above background art that the existing coating-type rubber coating equipment is difficult to control the coating amount, is prone to cause glue residue, and affects the overall performance of the shock absorber plate.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A rubber coating device for a retarder shock absorber plate includes a positioning sleeve arranged on a first mounting frame, and the shock absorber plate is arranged in the positioning sleeve on the first mounting frame; a spraying device is arranged on the positioning sleeve, and the spraying device includes: A second mounting frame, which is arranged on the top of the positioning sleeve; A first spraying chamber, which is arranged on the second mounting frame; A pair of second spraying chambers, which are arranged on opposite sides of the first spraying chamber; The first driving mechanism is installed on the second mounting bracket. The first driving mechanism is used to extrude the glue liquid in the second mounting bracket to spray the glue liquid. And a linkage mechanism is arranged between the first spraying chamber and the second spraying chamber. When the first driving mechanism extrudes the glue liquid in the second mounting bracket, it drives a pair of the second spraying chambers to rotate and spray the glue liquid.

[0007] Preferably, a plurality of spray holes for spraying the glue liquid are provided at the bottoms of the first spraying chamber and the second spraying chamber.

[0008] Preferably, the first driving mechanism includes a first cylinder arranged on the second mounting bracket and a push block arranged on the output shaft of the first cylinder. The push block is inserted into the first spraying chamber, and the push block is adapted to the inner cavity of the first spraying chamber.

[0009] Preferably, the linkage mechanism includes a first elastic member and a sector gear. The first elastic member is arranged between the first spraying chamber and the push block. The sector gear is arranged on the second spraying chamber, and a tooth groove meshing with the sector gear is provided on the first spraying chamber.

[0010] Preferably, the linkage mechanism further includes a compression mechanism. The compression mechanism is arranged between the second mounting bracket and the second spraying chamber. When the second spraying chamber rotates, the compression mechanism is used to squeeze the internal space of the second spraying chamber so that the glue liquid in the second spraying chamber is ejected through the spray holes.

[0011] Preferably, the compression mechanism includes a limiting plate and a flexible cloth. The limiting plate is fixedly arranged on the second mounting bracket, and the flexible cloth is arranged between the second spraying chamber and the limiting plate. The second spraying chamber, the flexible cloth and a part of the flexible cloth enclose a storage cavity for storing the glue liquid. When the second spraying chamber rotates, the glue liquid in the storage cavity is squeezed by the limiting plate.

[0012] Preferably, an adjusting mechanism is further included. The adjusting mechanism is used to generate negative pressure in the positioning sleeve to change the spraying trajectory of the glue liquid of the second mounting bracket and the first spraying chamber.

[0013] Preferably, the adjusting mechanism includes an air duct, a mounting plate and a second driving mechanism. The air duct is fixedly arranged on the positioning sleeve, and the inside of the positioning sleeve is communicated with the air duct through a through hole. The second driving mechanism is installed on the air duct and is used to generate suction in the air duct so that negative pressure is formed inside the positioning sleeve.

[0014] Preferably, a plurality of third cylinders are installed on the first mounting frame, and the output ends of the plurality of third cylinders are fixedly provided with the same placement plate, and the shock-absorbing plate is placed on the placement plate; the third cylinder is used to drive the shock-absorbing plate to move so that the glue-applying surface of the shock-absorbing plate moves into the positioning sleeve; a positioning block adapted to the shock-absorbing plate is provided on the placement plate and is used to position the shock-absorbing plate.

[0015] A working method of a retarder shock-absorbing plate rubber coating device includes the following steps: Step 1, vertical glue spraying: After the glue-applying surface of the shock-absorbing plate moves into the positioning sleeve, the first driving mechanism squeezes the internal space of the first spraying chamber, so that the glue liquid in the first spraying chamber is sprayed out through the spray holes onto the glue-applying surface of the shock-absorbing plate; Step 2, rotary glue spraying: As the first driving mechanism continues to squeeze the first spraying chamber for glue spraying, at the same time, a pair of second spraying chambers will be driven to rotate through the linkage mechanism, and the internal space of the second spraying chamber will be squeezed at the same time, so that the glue liquid in the second spraying chamber is sprayed out through the spray holes onto the glue-applying surface of the shock-absorbing plate, forming a fan-shaped glue spraying surface.

[0016] The beneficial effects of the present invention: 1. By setting the spraying device, the first driving mechanism applies pressure to the first spraying chamber, so that the internal glue liquid can be stably and evenly sprayed onto the glue-applying surface of the shock-absorbing plate through the spray holes. At the same time, the second spraying chamber can be synchronously driven to rotate and spray through the linkage mechanism, forming a unique fan-shaped dynamic spraying mode, which expands from the center of the shock-absorbing plate to the outside, realizing the uniform distribution of the glue liquid, ensuring the thickness consistency of the glue coating layer and the spraying efficiency, realizing the fan-shaped dynamic spraying of the shock-absorbing plate, and effectively improving the spraying efficiency and effect; 2.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-9 as shown, a retarder shock-absorbing plate rubber coating device, such as Figures 1-4As shown in the figure, it includes a positioning sleeve 2 arranged on the first mounting bracket 1, and a shock-absorbing plate 7 is arranged inside the positioning sleeve 2 on the first mounting bracket 1; a spraying device 3 is arranged on the positioning sleeve 2, and the spraying device 3 includes a second mounting bracket 31, a first spraying chamber 32, a pair of second spraying chambers 33, a first driving mechanism 34 and a linkage mechanism 35; wherein, the second mounting bracket 31 is arranged on the top of the positioning sleeve 2; the first spraying chamber 32 is arranged on the second mounting bracket 31; a pair of second spraying chambers 33 are arranged on opposite sides of the first spraying chamber 32, and a plurality of spray holes for spraying glue are arranged at the bottoms of the first spraying chamber 32 and the second spraying chambers 33; the first driving mechanism 34 is installed on the second mounting bracket 31, and the first driving mechanism 34 is used to squeeze the glue in the second mounting bracket 31 to spray the glue; the linkage mechanism 35 is arranged between the first spraying chamber 32 and the second spraying chambers 33; when the first driving mechanism 34 squeezes the glue in the second mounting bracket 31, it drives a pair of second spraying chambers 33 to rotate and spray the glue; it can be understood that the first spraying chamber 32 is communicated with the glue storage tank through a first rubber tube 37, the second spraying chambers 33 are communicated with the glue storage tank through second rubber tubes 38, and the connection positions of the first rubber tube 37 with the first spraying chamber 32 and the connection positions of the second rubber tubes 38 with the second spraying chambers 33 are all flexibly connected by hoses, and will not interfere with the movement or rotation of the first spraying chamber 32 and the second spraying chambers 33.

[0022] It should be noted that in the glue coating process of the shock-absorbing plate 7 of the present invention, a fan-shaped dynamic spraying of the glue coating of the shock-absorbing plate 7 is realized, effectively improving the spraying efficiency and effect; in order to ensure that the glue can be evenly and accurately applied to the specified position and avoid the pollution of the non-glue coating surface and the waste of glue, first, the glue coating surface of the shock-absorbing plate 7 is accurately moved to the bottom of the positioning sleeve 2 and closely attached thereto, which not only provides a stable basis for subsequent operations, but also prevents the glue from splashing to the non-glue coating surface through the effective covering of the positioning sleeve 2, thereby ensuring the spraying effect and reducing the pollution.

[0023] Then the first driving mechanism 34 is started to apply pressure to the first spraying chamber 32, so that the glue inside can be stably and evenly sprayed onto the glue coating surface of the shock-absorbing plate 7 through the spray holes. At the same time, the first driving mechanism 34 synchronously drives the second spraying chambers 33 to rotate through the linkage mechanism 35. As the second spraying chambers 33 rotate, the internal space is gradually compressed, and then the glue inside is also forced to spray downward through the corresponding spray holes. The coordinated operation of these two spraying chambers forms a unique fan-shaped dynamic spraying mode, which expands from the center of the shock-absorbing plate 7 to the outside, realizing the uniform distribution of the glue and ensuring the thickness consistency and spraying efficiency of the glue coating layer.

[0024] The entire spraying process proceeds orderly under the protection of the positioning sleeve 2, effectively avoiding the phenomenon of mis-spraying the glue, greatly improving the spraying effect and quality, ensuring the cleanliness of the production environment, and ultimately realizing an efficient, precise and environmentally friendly gluing process for the shock-absorbing plate 7.

[0025] Please refer to Figures 5-7 , in an optional embodiment, the first driving mechanism 34 includes a first air cylinder 341 disposed on the second mounting frame 31 and a push block 342 disposed on the output shaft of the first air cylinder 341; the push block 342 is inserted into the first spraying chamber 32, and the push block 342 is adapted to the inner cavity of the first spraying chamber 32.

[0026] It should be noted that when the first air cylinder 341 receives the start signal, it will accurately push the push block 342 to move. As the push block 342 advances, it gradually compresses the internal space of the first spraying chamber 32, and this action effectively leads out the glue in the spraying chamber through a special spraying hole, ensuring that the glue can be sprayed stably and evenly onto the gluing surface of the shock-absorbing plate 7.

[0027] During this process, the power provided by the first air cylinder 341 not only ensures the accuracy and stability of the movement of the push block 342, but also ensures that the pressure control of the glue in the first spraying chamber 32 is just right, avoiding the problem of inconsistent glue spraying caused by uneven pressure. In this way, we can achieve high-quality glue spraying at the central position of the gluing surface of the shock-absorbing plate 7, providing a solid foundation for the subsequent process, and ensuring the efficiency and reliability of the entire spraying process.

[0028] Please refer to Figures 5-9 , in an optional embodiment, the linkage mechanism 35 includes a first elastic member 351 and a sector gear 352; the first elastic member 351 is disposed between the first spraying chamber 32 and the push block 342; the first spraying chamber 32 is slidably connected to the second mounting frame 31, and a second elastic member is disposed between the first spraying chamber 32 and the second mounting frame 31; the sector gear 352 is disposed on the second spraying chamber 33, and a tooth groove 353 meshing with the sector gear 352 is formed on the first spraying chamber 32.

[0029] It should be noted that as the push block 342 gradually compresses the internal space of the first spraying chamber 32, this action not only promotes the accurate derivation of the glue through the spraying hole, but also triggers a series of precise mechanical linkages. Specifically, the advancement of the push block 342 causes the first elastic member 351 connected to the first spraying chamber 32 to be subjected to a compressive force, and at the same time, the second elastic member begins to elongate under the reaction force. This design ensures that when the push block 342 applies pressure, it can not only effectively push the first spraying chamber 32 to move, but also maintain the balance and stability of the entire system.

[0030] During the process of the pushing block 342 pushing the first spraying bin 32 to move, the displacement of the first spraying bin 32 triggered the cooperative movement between the sector gear 352 and the tooth groove 353. The sector gear 352 began to rotate under the guidance of the tooth groove 353, and then drove the second spraying bin 33 to rotate synchronously through the mechanical transmission system. This series of chain reactions achieved a highly coordinated action between the two spraying bins, ensuring that the glue liquid evenly diffused from the center of the shock-absorbing plate 7 to both sides, forming an ideal spraying effect.

[0031] Throughout the process, the collaborative work between various components not only ensured the accuracy and consistency of spraying, but also demonstrated the high efficiency and reliability of the system under complex operations, providing solid technical support for achieving high-quality gluing processes.

[0032] Please refer to Figures 5-9 , in an optional embodiment, the linkage mechanism 35 further includes a compression mechanism 354; the compression mechanism 354 is disposed between the second mounting bracket 31 and the second spraying bin 33; when the second spraying bin 33 rotates, the compression mechanism 354 is used to squeeze the internal space of the second spraying bin 33 so that the glue liquid in the second spraying bin 33 is ejected through the spray holes; the compression mechanism 354 includes a limit plate 3541 and a flexible cloth 3542; the limit plate 3541 is fixedly arranged on the second mounting bracket 31, and the flexible cloth 3542 is disposed between the second spraying bin 33 and the limit plate 3541; the second spraying bin 33, the flexible cloth 3542 and a part of the flexible cloth 3542 enclose a storage cavity for storing the glue liquid; when the second spraying bin 33 rotates, the glue liquid in the storage cavity is squeezed by the limit plate 3541.

[0033] It should be noted that while driving the second spraying bin 33 to rotate, pressure is applied to the flexible cloth 3542 through the limit plate 3541. As the limit plate 3541 advances, it gradually squeezes the flexible cloth 3542, and this action effectively reduces the internal space of the second spraying bin 33. This design not only ensures that the internal glue liquid is subjected to uniform pressure, but also promotes the smooth discharge of the glue liquid through the spray holes, forming a fan-shaped automatic spraying surface.

[0034] During this process, the precise cooperation between the limit plate 3541 and the flexible cloth 3542 is the key to achieving uniform glue spraying. When the second spraying bin 33 rotates under the action of the linkage mechanism 35, the limit plate 3541 continuously applies pressure to the flexible cloth 3542. This enables the glue liquid in the second spraying bin 33 to be evenly extruded during rotation and sprayed outward through the spray holes. The resulting fan-shaped spraying pattern ensures that the glue liquid evenly diffuses from the center of the shock-absorbing plate 7 to both sides, achieving an ideal spraying effect.

[0035] Please refer to Figures 1-2, in an alternative embodiment, it further includes an adjusting mechanism 36, and the adjusting mechanism 36 is used to generate negative pressure inside the positioning sleeve 2 to change the trajectory of the glue sprayed by the second mounting bracket 31 and the first spraying chamber 32; the adjusting mechanism 36 includes an air duct 361, a mounting plate 362 and a second driving mechanism; the air duct 361 is fixedly arranged in the positioning sleeve 2, and the inside of the positioning sleeve 2 is communicated with the air duct 361 through a through hole; the second driving mechanism is installed on the air duct 361 and is used to generate suction force inside the air duct 361 so that negative pressure is formed inside the positioning sleeve 2; It can be understood that the present application does not limit the specific structure and installation method of the second driving mechanism. The following only provides a feasible technical solution; a mounting plate 362 is fixedly arranged at the outlet position of the air duct 361, a second cylinder 363 is installed on the mounting plate 362, a piston plate 364 is slidably connected inside the air duct 361, the output end of the second cylinder 363 is inserted into the air duct 361 and connected to the piston plate 364, and by driving the piston plate 364 to move, negative pressure is generated inside the air duct 361.

[0036] It should be noted that during the spraying process by the cooperation of the first spraying chamber 32 and the second spraying chamber 33, negative pressure is formed inside the air duct 361 by the second driving mechanism, so that the glue sprayed in the first spraying chamber 32 and the second spraying chamber 33 is further sprayed to both sides, increasing the spraying area and further improving the glue spraying uniformity.

[0037] Please refer to Figures 1-2 , in an alternative embodiment, a plurality of third cylinders 5 are installed on the first mounting bracket 1, and the output ends of the plurality of third cylinders 5 are fixedly provided with the same placing plate 4, and the shock-absorbing plate 7 is placed on the placing plate 4; the third cylinder 5 is used to drive the shock-absorbing plate 7 to move so that the glue coating surface of the shock-absorbing plate 7 moves into the positioning sleeve 2; positioning blocks 6 adapted to the shock-absorbing plate 7 are provided on the placing plate 4 and are used to position the position of the shock-absorbing plate 7.

[0038] It should be noted that when the shock-absorbing plate 7 is placed on the placing plate 4, the shock-absorbing plate 7 is positioned by the positioning block 6, and at the same time, the through-hole structure on the shock-absorbing plate 7 is blocked by the positioning block 6, so that when the third cylinder 5 drives the shock-absorbing plate 7 to rise and fit with the bottom of the positioning sleeve 2, only the suction force moving towards the air duct 361 can be formed inside the positioning sleeve 2, increasing the spraying amplitude of the glue to both sides, and thus increasing the spraying range and spraying uniformity.

[0039] Please refer to Figures 1-10 , a working method of a retarder shock-absorbing plate rubber coating device, includes the following steps: Step 1, vertical glue spraying: After the glue coating surface of the shock-absorbing plate 7 moves into the positioning sleeve 2, the first driving mechanism 34 is used to squeeze the internal space of the first spraying chamber 32, so that the glue in the first spraying chamber 32 is ejected through the spray holes onto the glue coating surface of the shock-absorbing plate 7; Step 2: Rotate and spray glue: As the first driving mechanism 34 continues to squeeze the first spraying chamber 32 to spray glue, the linkage mechanism 35 will drive a pair of second spraying chambers 33 to rotate, and at the same time squeeze the internal space of the second spraying chambers 33, so that the glue liquid in the second spraying chambers 33 is ejected through the spray holes onto the glue application surface of the shock absorber plate 7, forming a fan-shaped glue spraying surface.
