Description

Technical Field

[0001] This utility model relates to an automated coating device, specifically an automated coating device for the production of electrolytic hydrogen-generated sealing gaskets. Background Technology

[0002] Gaskets used in electrolytic hydrogen production equipment require extremely high levels of corrosion resistance, sealing performance, and high-temperature resistance. Applying coating materials (epoxy resin, PTFE, silicone sealant, etc.) to the gaskets can significantly improve their performance. Common coating equipment includes spray coating machines.

[0003] A typical spray painting machine includes a worktable, a spraying module, and a drive module. The spray nozzle of the spraying module is aligned with the worktable. In use, the sealing gasket is placed flat on the worktable, and the drive module drives the worktable to rotate, thereby rotating the sealing gasket. During the rotation, the spraying module sprays the sealing gasket.

[0004] In common spraying modules, the spraying range is fan-shaped, and the amount of coating applied within the fan-shaped area varies. Since common spraying devices fix the gasket by friction between the worktable and the sealing gasket (the sealing gasket does not move relative to the worktable), the rotation of the worktable can drive the sealing gasket to rotate. This setting can improve the feeding efficiency, but during the feeding process, the coaxiality between the sealing gasket and the worktable cannot be guaranteed, which can easily cause the sealing gasket to rotate eccentrically. This results in different contact points between the sealing gasket and the spraying range of the spraying module, which can easily lead to uneven coating and affect the performance of the product.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Please see Figures 1-7 As an embodiment of this utility model, the automated coating device for producing electrolytic hydrogen sealing gaskets includes a chassis 1; a spraying module 2 is installed on the chassis 1.

[0041] It also includes a mounting frame 3, which is rotatably mounted on the chassis 1, and a workbench 301 is mounted on the mounting frame 3;

[0042] The clamping component includes multiple sets of clamping plates 4 slidably mounted on the worktable 301; the clamping plates 4 are capable of sliding along the radial direction of the worktable 301 to clamp or release the sealing gasket; and the multiple sets of clamping plates 4 are equidistantly arranged along the circumference of the worktable 301.

[0043] It also includes a driving component, which is used to drive the clamping plate 4 to rotate synchronously with the worktable 301.

[0044] In this embodiment, in the initial state, the axial distance between the multiple sets of clamping plates 4 and the worktable 301 is small; in this state, it is convenient to feed the electrolytic hydrogen production sealing gasket (place it on the worktable 301).

[0045] After the sealing gasket is placed on the worktable 301, it is positioned and clamped by the clamping components. During this process, multiple clamping plates 4 slide radially along the worktable 301 to gradually move away from the axis of the worktable 301. As the clamping plates 4 move, the distance between them and the axis of the worktable 301 gradually increases. During the movement, the clamping plates 4 come into contact with the inner wall of the sealing gasket and drive the sealing gasket to move, so that the axis of the sealing gasket gradually coincides with the axis of the worktable 301.

[0046] Subsequently, the driving component will drive the worktable 301 and the clamping plate 4 to rotate synchronously, thereby driving the sealing gasket to rotate (the rotation center of the worktable 301 coincides with the rotation center of the sealing gasket); during the rotation process, the surface of the sealing gasket is sprayed by the spraying module 2; thus completing the coating of the electrolytic hydrogen production sealing gasket.

[0047] The gasket is clamped and positioned by the clamping device to ensure that there is no eccentricity between the gasket and the worktable 301 when it rotates. At this time, when the spraying module 2 sprays the rotating gasket, the distance, angle and height from each part of the gasket to the nozzle are consistent, the uniformity of the coating thickness is greatly improved, and the problem of local excessive thickness or thinness caused by traditional eccentric rotation is avoided, effectively improving the sealing performance.

[0048] As a further embodiment of this utility model, the clamping member includes a turntable 8 rotatably mounted within the mounting frame 3, the turntable 8 having inclined grooves 801 equidistantly arranged along the circumference; the worktable 301 having straight grooves 302 equidistantly arranged along the circumference; a pressing plate 6 connected to the clamping plate 4; and a slider 602 slidably engaged with the straight groove 302 and a sliding column 603 slidably connected to the inclined groove 801 mounted on the pressing plate 6.

[0049] In this embodiment, when the sealing gasket is placed on the worktable 301, the turntable 8 rotates, thereby driving the inclined groove 801 to rotate synchronously. Through the squeezing action of the inclined groove 801 wall on the sliding column 603, the slider 602 can be driven to slide in the straight groove 302, thereby driving the squeezing plate 6 to move away from the axis of the worktable 301, so as to drive the clamping plate 4 to move, so as to clamp and position the sealing gasket. During the clamping process, the clamping plate 4 will contact the inner wall of the sealing gasket and drive the sealing gasket to move, so that the axis of the sealing gasket gradually coincides with the axis of the worktable 301.

[0050] The gasket is clamped and positioned by the clamping device to ensure that there is no eccentricity between the gasket and the worktable 301 when it rotates. At this time, when the spraying module 2 sprays the rotating gasket, the distance, angle and height from each part of the gasket to the nozzle are consistent, the uniformity of the coating thickness is greatly improved, and the problem of local excessive thickness or thinness caused by traditional eccentric rotation is avoided, effectively improving the sealing performance.

[0051] As a further embodiment of this utility model, the clamping member further includes a telescopic column 401 installed on the clamping plate 4; a telescopic sleeve 601 that slides and engages with the telescopic column 401 is installed on the extrusion plate 6; a spring 5 is provided inside the telescopic sleeve 601; and the two ends of the spring 5 abut against the telescopic column 401 and the telescopic sleeve 601 respectively.

[0052] In this embodiment, when the extrusion plate 6 moves away from the axis of the worktable 301, it will drive the clamping plate 4 to move synchronously through the telescopic column 401, the telescopic sleeve 601, and the spring 5. After multiple clamping plates 4 have contacted the inner wall of the sealing gasket, the continuing to move extrusion plate 6 will drive the telescopic sleeve 601 to approach the clamping plate 4, so that the telescopic column 401 slides inward in the telescopic sleeve 601 and compresses the spring 5. The elastic force of the spring 5 can prevent the sealing gasket from being damaged due to excessive force, which can effectively improve the spraying quality.

[0053] As a further embodiment of this utility model, the driving component includes a motor 9 mounted on the housing 1; a lead screw 10 is mounted on the output end of the motor 9; a threaded sleeve 11 is threadedly connected to the lead screw 10; a first rotating shaft 7 and a second rotating shaft 14 are rotatably mounted on the housing 1; wherein the first rotating shaft 7 is fixedly connected to the turntable 8; a second pulley 1404 is mounted on the second rotating shaft 14; a first pulley 303 is mounted on the mounting frame 3; the first pulley 303 and the second pulley 1404 are connected by a belt; a first sleeve 12 and a second sleeve 13 are mounted on the threaded sleeve 11, respectively engaging with the first rotating shaft 7 and the second rotating shaft 14; a first protruding post 1201 is mounted on the first sleeve 12; a second protruding post 1301 is mounted on the second sleeve 13; a first groove group is formed on the first rotating shaft 7 that slides with the first protruding post 1201; a second groove group is formed on the second rotating shaft 14 that slides with the second protruding post 1301.

[0054] In this embodiment, after the sealing gasket is placed on the workbench 301, the motor 9 is started, thereby driving the lead screw 10 to rotate, and through the threaded engagement, driving the threaded sleeve 11 to move from one end to the other along the length direction of the lead screw 10; during this process, the first sleeve 12 and the second sleeve 13 will move on the first rotating shaft 7 and the second rotating shaft 14 respectively, thereby driving the first protruding post 1201 to slide in the first groove group, and driving the second protruding post 1301 to slide in the second groove group.

[0055] During the clamping and positioning process, the first rotating shaft 7 is driven to rotate by the sliding engagement of the first protruding post 1201 and the first groove group, thereby driving the turntable 8 to rotate; during this process, the second rotating shaft 14 is restricted to rotate by the squeezing engagement of the second protruding post 1301 and the second groove group, thereby keeping the worktable 301 stationary.

[0056] Spraying process: Through the sliding engagement of the first protruding post 1201 with the first groove group and the sliding engagement of the second protruding post 1301 with the second groove group, the first rotating shaft 7 and the second rotating shaft 14 can be driven to rotate synchronously. Thus, through the engagement of the first pulley 303 and the second pulley 1404, the turntable 8 and the worktable 301 rotate synchronously (the inclined groove 801 and the straight groove 302 remain relatively stationary).

[0057] Release process: The first rotating shaft 7 is driven to rotate by the sliding engagement of the first protruding post 1201 and the first groove group, thereby driving the turntable 8 to rotate in the opposite direction; during this process, the second rotating shaft 14 can be restricted to rotate by the squeezing engagement of the second protruding post 1301 and the second groove group, thereby keeping the worktable 301 stationary.

[0058] The gasket is clamped and positioned by the clamping device to ensure that there is no eccentricity between the gasket and the worktable 301 when it rotates. At this time, when the spraying module 2 sprays the rotating gasket, the distance, angle and height from each part of the gasket to the nozzle are consistent, the uniformity of the coating thickness is greatly improved, and the problem of local excessive thickness or thinness caused by traditional eccentric rotation is avoided, effectively improving the sealing performance.

[0059] As a further embodiment of the present invention, the first groove group includes a first inclined groove 701 and a second inclined groove 702; wherein one end of the first inclined groove 701 is connected to one end of the second inclined groove 702, and the inclination directions of the first inclined groove 701 and the second inclined groove 702 are opposite.

[0060] As a further embodiment of this utility model, the second groove group includes a first vertical groove 1401, a third inclined groove 1402, and a second vertical groove 1403; wherein the two ends of the third inclined groove 1402 are respectively connected to one end of the first vertical groove 1401 and one end of the second vertical groove 1403, and the third inclined groove 1402 and the first inclined groove 1401 have the same inclination direction.

[0061] In this embodiment, during the clamping process: the first protruding post 1201 slides in the first inclined groove 701 toward the second inclined groove 702, and the second protruding post 1301 slides in the first vertical groove 1401; through the squeezing action of the first protruding post 1201 on the groove wall of the first inclined groove 701, the first rotating shaft 7 can be driven to rotate, thereby driving the turntable 8 to rotate, while the second rotating shaft 14 does not rotate.

[0062] Spraying process: The first protruding post 1201 continues to slide in the first inclined groove 701 towards the second inclined groove 702, and the second protruding post 1301 slides in the third inclined groove 1402. Through the squeezing action of the first protruding post 1201 on the groove wall of the first inclined groove 701, and through the squeezing action of the second protruding post 1301 on the third inclined groove 1402 (the third inclined groove 1402 and the first inclined groove 701 have the same inclination direction), the first rotating shaft 7 and the second rotating shaft 14 can be driven to rotate synchronously, so that the turntable 8 and the worktable 301 rotate synchronously.

[0063] Release process: The first protruding post 1201 slides away from the first inclined groove 701 in the second inclined groove 702, and the second protruding post 1301 slides away from the third inclined groove 1402 in the second vertical groove 1403; the first protruding post 1201 squeezes the groove wall of the second inclined groove 702, which can drive the first rotating shaft 7 to rotate; while the second rotating shaft 14 does not rotate; and since the first inclined groove 701 and the second inclined groove 702 are inclined in opposite directions, the turntable 8 can rotate in the opposite direction, thereby driving the clamping plate 4 to move in the opposite direction to the axis of the worktable 301 to release the sealing gasket.

[0064] The gasket is clamped and positioned by the clamping device to ensure that there is no eccentricity between the gasket and the worktable 301 when it rotates. At this time, when the spraying module 2 sprays the rotating gasket, the distance, angle and height from each part of the gasket to the nozzle are consistent, the uniformity of the coating thickness is greatly improved, and the problem of local excessive thickness or thinness caused by traditional eccentric rotation is avoided, effectively improving the sealing performance.

[0065] As a further embodiment of this utility model, the clamping plate 4 is inclined, with its inclination direction facing the axis of the worktable 301.

[0066] In this embodiment, the inclined clamping plate 4 can reduce the difficulty of placing the sealing gasket and guide the sealing gasket to fall smoothly onto the worktable 301, thereby improving the spraying efficiency.

[0067] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
