Description

A clamping mechanism for a powder coating gun in a powder coating booth Technical Field

[0001] This application relates to the field of powder coating gun clamping technology, and in particular to a clamping mechanism for a powder coating gun used in a powder coating booth. Background Technology

[0002] Powder coating technology is widely used in modern industry, especially in the field of metal surface treatment. It involves spraying plastic powder onto the surface of a workpiece and then heating and curing it to form a protective or decorative layer. Powder coating not only improves the corrosion resistance and wear resistance of products but also enhances their appearance.

[0003] Powder coating is usually carried out in a powder coating booth. In the current technology, workers need to be in the powder coating booth to carry out powder coating operations. Although they wear protective clothing during the operation, it is still inevitable that it will cause certain hazards to the workers.

[0004] Therefore, this application provides a clamping device that can increase the automation of powder coating guns, reduce the time workers spend in the powder coating room, and thus reduce the health hazards of powder coating operations to workers. Summary of the Invention

[0005] In order to reduce the time workers spend in the powder coating booth and thus reduce the health hazards of powder coating operations, this application provides a clamping mechanism for powder coating guns in a powder coating booth.

[0006] The clamping mechanism for a powder coating gun in a powder coating booth provided in this application adopts the following technical solution:

[0007] A clamping mechanism for a powder coating gun in a powder coating booth includes a sliding track, a base, a first driving member, a second driving member, and a clamping assembly. The end of the sliding track is mounted on the inner wall of the powder coating booth, and the base is slidably connected to the sliding track. The first driving member drives the base to slide relative to the sliding track. The second driving member is mounted on the base, and the clamping assembly is mounted on the output end of the second driving member. The second driving member drives the clamping assembly to move relative to the base.

[0008] By adopting the above technical solution, during powder coating operations, the first driving component drives the base to move relative to the slide rail, moving the base, clamping assembly, and powder coating gun to the powder coating position; then, the second driving component moves the clamping assembly relative to the base, thereby moving the powder coating gun to perform preliminary powder coating on the product in the powder coating booth. Afterwards, the workers enter the powder coating booth for secondary supplementary powder coating, thereby reducing the time workers spend in the powder coating booth and thus reducing the health hazards of powder coating operations to workers.

[0009] Optionally, the clamping assembly includes a connector, a first mounting plate, and a second mounting plate. The connector is used to connect to the second driving member. Both the first mounting plate and the second mounting plate are connected to the connector. The first mounting plate and the second mounting plate are disposed opposite to each other. A first airbag is disposed on the surface of the first mounting plate facing the second mounting plate, and a second airbag is disposed on the surface of the second mounting plate facing the first mounting plate.

[0010] By adopting the above technical solution, the first airbag and the second airbag are used to clamp the spray gun, which reduces wear on the spray gun shell and is applicable to spray guns of different sizes, ensuring the flexibility of the clamping components.

[0011] Optionally, multiple first airbags are provided, and the multiple first airbags are evenly distributed on the first mounting plate.

[0012] By adopting the above technical solution, on the one hand, it ensures that the force on the powder coating gun is more uniform during the clamping process, avoiding damage or deformation of the powder coating gun surface due to excessive local pressure. On the other hand, the evenly distributed first airbag can also adapt to powder coating guns of different shapes and sizes, improving the applicability and stability of the clamping mechanism.

[0013] Optionally, multiple second airbags are provided, and the multiple second airbags are evenly distributed on the second mounting plate.

[0014] By adopting the above technical solution, the second mounting plate in the clamping assembly can perform multi-point contact clamping of the spray gun through multiple evenly distributed second airbags, making the clamping force more uniform and effectively avoiding the problem of damage to the spray gun or unstable clamping caused by single-point force, thereby improving the stability and safety of the spray gun during operation.

[0015] Optionally, the first airbag is detachably connected to the first mounting plate.

[0016] By adopting the above technical solution, a detachable connection is achieved between the first airbag and the first mounting plate, facilitating quick replacement when the first airbag is worn or damaged, thereby reducing maintenance costs and improving equipment efficiency. Furthermore, the specifications or performance of the first airbag can be flexibly adjusted according to actual needs, further enhancing the adaptability of the clamping mechanism.

[0017] Optionally, the second airbag is detachably connected to the second mounting plate.

[0018] By adopting the above technical solution, the second airbag of the clamping mechanism is detachably connected to the second mounting plate. This allows for quick disassembly and replacement of the second airbag when it is damaged or needs to be replaced, improving the convenience of equipment maintenance and reducing repair costs. Simultaneously, it also facilitates the cleaning and maintenance of the second airbag, extending the overall service life of the clamping mechanism.

[0019] Optionally, the first airbag is provided with a first vent, and the first airbag is provided with a first nut at the vent; the first mounting plate is provided with a first screw for threaded engagement with the first nut, the first screw is provided with a first vent chamber inside, and the end of the first vent chamber passes through the end of the screw.

[0020] By adopting the above technical solution, the first airbag and the first mounting plate are detachably connected, while ensuring that gas can be inflated or deflated by the first ventilation chamber.

[0021] Optionally, the surface of the first airbag is provided with a plurality of cross grooves, which are evenly distributed in the first airbag; the cross grooves are filled with nano-adhesive.

[0022] By adopting the above technical solution, the friction between the first airbag and the spray gun is increased, thereby improving clamping stability. Simultaneously, the cross-groove design allows the first airbag to better adapt to the surface contour of the spray gun under force, further enhancing the clamping effect. The use of nano-adhesive also provides additional adhesion without affecting the airbag's elasticity, preventing the spray gun from slipping during clamping.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the sliding rail, the first driving component, the base and the second driving component, the spray gun can be accurately positioned and flexibly moved in the spray booth, realizing partial automation of the spraying operation, reducing the time workers spend in the spray booth, and thus reducing the health hazards of the spraying operation to workers.

[0025] 2. The design of the first and second airbags provides a gentle and reliable clamping force through evenly distributed pressure, avoiding damage to the spray gun while ensuring the reliability of clamping;

[0026] 3. Multiple first airbags and multiple second airbags are provided to form a multi-point clamping for the spray gun, further enhancing the clamping stability of the clamping component for the spray gun, and making the clamping component more suitable for spray guns of various sizes.

The second driving member 4 is used to drive the clamping assembly 5 to move relative to the base 2.

[0033] Specifically, the sliding track 1 includes a guide rail 11 and a slider 12, with a base 2 mounted on the slider 12. The guide rail 11 is made of high-strength aluminum alloy, possessing excellent wear resistance and deformation resistance. The slider 12 is slidably connected to the guide rail 11 via ball bearings. The slider 12 can be replaced with other types of sliding connectors 51, such as linear bearings or sliding bushings; the specific selection depends on the actual operating environment and load conditions. The connection structure between the slider 12 and the guide rail 11 employs a ball circulation mechanism, ensuring smooth sliding and low friction. Furthermore, the lubrication channel of the ball circulation mechanism is designed in a spiral shape to facilitate the uniform distribution of lubricating oil.

[0034] The base 2 includes a base plate and a support frame. The base plate is made of steel plate with an anti-corrosion treatment to adapt to the complex environment inside the powder coating booth. The base plate is bolted to the slider 12, and elastic gaskets are installed at the connection to reduce vibration transmission. The support frame is welded to the base plate and adopts a triangular structure design to ensure overall stability. The support frame can be made of stainless steel or carbon steel; the specific choice should consider cost and corrosion resistance requirements.

[0035] The first drive component 3 is a rodless cylinder. The second drive component 4 is either a pneumatic cylinder or a hydraulic cylinder. Pneumatic cylinders are suitable for light-load applications, while hydraulic cylinders are suitable for heavy-load applications; the choice can be made based on actual needs. The piston rod of the second drive component 4 is connected to the clamping assembly 5.

[0036] The clamping assembly 5 includes a connector 51, a first mounting plate 52, and a second mounting plate 53. The connector 51 is made of high-strength steel and is connected to the piston rod of the cylinder by bolts. An anti-loosening nut 542 is provided at the connection to prevent loosening due to vibration. The first mounting plate 52 and the second mounting plate 53 are both connected to the connector 51 by welding or bolts, and the two are arranged opposite each other to form a clamping space.

[0037] The surfaces of the first mounting plate 52 and the second mounting plate 53 of the clamping assembly 5 are respectively provided with a plurality of first airbags 54 and second airbags 55. The first airbags 54 and the second airbags 55 are both made of flexible material, which has good cushioning performance and can effectively protect the surface of the spray gun from damage.

[0038] Multiple first airbags 54 are provided, and the multiple first airbags 54 are evenly distributed on the first mounting plate 52. Each airbag is connected to the others through an air tube to ensure uniform pressure distribution. Multiple second airbags 55 are also provided, and are evenly distributed on the second mounting plate 53. Their structure is the same as that of the first airbags 54.

[0039] Furthermore, the first airbag 54 and the first mounting plate 52 are detachably connected for easy replacement and maintenance. The first airbag 54 is provided with a vent 541, and a nut 542 is provided at the vent 541. A screw 56 is welded and fixed to the first mounting plate 52, and the nut 542 is threadedly engaged with the screw 56 on the first mounting plate 52. The screw 56 has a venting chamber inside, and the end of the venting chamber extends through the end of the screw 56 to facilitate air source access.

[0040] It is understandable that the second airbag 55 and the second mounting plate 53 are also detachably connected, and the structure and method of the detachable connection are the same as the structure and method of the detachable connection between the first airbag 54 and the first mounting plate 52.

[0041] Furthermore, the surface of the first airbag 54 is provided with multiple cross grooves 543, which are filled with nano-adhesive, increasing the adhesion between the first airbag 54 and the spray gun, and further improving the clamping stability of the clamping assembly 5.

[0042] The implementation principle of the clamping mechanism for a spray gun in a spray booth according to an embodiment of this application is as follows: During spraying, the spray gun is placed between the first airbag 54 and the second airbag 55, and gas is injected into the first airbag 54 and the second airbag 55. The first airbag 54 and the second airbag 55 gradually expand and come into contact with the spray gun, thereby clamping the spray gun.

[0043] Then, through the cooperation of the slide rail, the first drive component 3 and the second drive component 4, the spray gun is moved in the spray booth to perform preliminary spray coating on the product.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
