Description

Technical Field

[0001] This utility model relates to the field of surface treatment, and more specifically to a plasma surface treatment device. Background Technology

[0002] Surface treatment is a method of processing or treating the surface of an object through specific processes or techniques, aimed at improving its appearance, performance, and function. Examples include cleaning, sanding, or scratching the surface of an object to prepare it for subsequent processing, such as cleaning a cup, acrylic sheet, or glass to prepare it for subsequent printing.

[0003] Currently, when cleaning object surfaces, preliminary cleaning can usually be done by wiping away surface dust and loose dirt with water. Deep cleaning can also be achieved by using appropriate cleaning agents to target contaminants. Laser cleaning and microsphere deposition methods are also available for cleaning specific materials or complex contaminants. However, existing treatment devices cannot simultaneously clean the object surface and enhance its adhesion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a plasma surface treatment device that can adjust the particles emitted by the plasma emitter to fully impact the surface of an object, thereby cleaning the object and enhancing its adhesion.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A plasma surface treatment apparatus includes a transport mechanism for transporting products to be treated and a frame for mounting the transport mechanism. Two side frames are fixed to the frame, and upper support frames are fixed to the two side frames. Two slide rails are symmetrically arranged on the upper support frames. A transverse movement mechanism is slidably connected to each slide rail. A lifting mechanism is provided on each transverse movement mechanism. A rotation mechanism is provided on each lifting mechanism. A plasma emitting head is fixed to each rotation mechanism. Each plasma emitting head is connected to a plasma emitter.

[0007] Preferably, the plasma emitter is located at the lower part of the frame, and the outer cover is provided with two through holes. The pipeline connecting each plasma emitter head to the plasma emitter passes through its corresponding through hole.

[0008] Preferably, the transport mechanism includes two pairs of mounting plates fixed to the upper part of the frame. Each pair of mounting plates is connected to the other pair of mounting plates through two auxiliary plates. Each pair of mounting plates is rotatably connected to a synchronous pulley. The two synchronous pulleys are driven by a synchronous belt. A first motor that drives the corresponding synchronous pulley to rotate is fixed to one of the mounting plates. A support plate is provided at the lower part of the synchronous belt. Multiple upright legs are provided on the support plate and fixed to the frame.

[0009] Preferably, two constraint plates with constraint timing belts are fixed to the two pairs of mounting plates.

[0010] Preferably, the two transverse moving mechanisms slide synchronously in opposite directions, and the sliding direction of the two transverse moving mechanisms is perpendicular to the direction of the product transported by the transport mechanism.

[0011] Preferably, the two lifting mechanisms drive the two rotary mechanisms to lift and lower synchronously, and the distance between them and the products transported by the transport mechanism is the same.

[0012] Preferably, two rotary mechanisms drive two plasma emission heads to rotate reciprocally.

[0013] Preferably, the end of the exhaust pipe is provided with an exhaust mechanism that drives fluid movement.

[0014] Preferably, the transport mechanism is symmetrically provided with guiding mechanisms for the products to be transported under limited conditions.

[0015] Preferably, the outer cover has a shielding mechanism detachably connected to both sides corresponding to the products transported by the transport mechanism.

[0027] See details Figure 1 , Figure 2 , Figures 5 to 7 Detailed examples of fully treating the surface of an object:

[0028] The plasma surface treatment apparatus includes a transport mechanism for transporting the product to be treated, and a frame 11 for mounting the transport mechanism. Two side frames 23 are fixedly connected to the frame 11, and upper support frames 24 are fixedly connected to the two side frames 23. Two symmetrical slide rails 25 are arranged on the upper support frames 24. A transverse movement mechanism is slidably connected to each slide rail 25, and a lifting mechanism is provided on each transverse movement mechanism. A rotation mechanism is provided on each lifting mechanism. A plasma emission head 42 is fixedly connected to each rotation mechanism, and each plasma emission head 42 is connected to a plasma emitter. An outer cover 61 is fixedly connected to the two upper support frames 24, and an exhaust pipe 63 is located at the top of the outer cover 61.

[0029] The transport mechanism can transport products with surfaces to be treated, such as cups, acrylic sheets, or glassware. When the transport mechanism is activated to transport the products, the plasma emitter starts, emitting particles through the plasma emitter head 42. When the product is transported to the lower part of the plasma emitter head 42, the particles emitted by the plasma emitter head 42 impact the surface of the transported product, effectively dispersing oil stains and cleaning the product surface. At the same time, the impact of the particles enhances the adhesion of the product surface, facilitating subsequent processing such as spraying or printing on the product surface. For example, after cleaning the exterior of cups, acrylic sheets, or glassware, patterns can be printed on them. The removed oil stains can be discharged through the upper exhaust pipe 63, the end of which is equipped with an exhaust mechanism that drives fluid movement.

[0030] The exhaust mechanism can be an existing fan or suction mechanism, which can accelerate the flow of fluid in the exhaust pipe 63, thereby creating a negative pressure environment in the exhaust pipe 63. Under negative pressure, the fluid flow carries away the oil and heat from the lower part of the exhaust pipe 63 and discharges it.

[0031] The outer cover 61 can cover the space where the product is being surface treated, effectively blocking the oil stains being treated and more fully covering the space filled with oil stains and heat, thereby ensuring that a negative pressure space can be formed inside the exhaust pipe 63 to fully remove the oil stains and heat generated during the cleaning process.

[0032] The rotary mechanism drives the plasma emitter 42 to reciprocate, allowing it to rotate around its own axis. This ensures that the emitted ions are evenly dispersed and impact the product surface, ensuring thorough cleaning. The lifting mechanism drives the rotary mechanism to raise and lower the plasma emitter 42, adjusting its distance from the surface and thus the impact force of the particles. This allows for adjustment of the surface treatment effect. Furthermore, the sliding mechanism allows the two plasma emitters 42 to be offset in the transport direction, adjusting the width of their impact on the surface and enabling cleaning of surfaces of varying widths.

[0033] The lateral movement mechanism includes a sliding sleeve 31 slidably connected to the slide rail 25. A slide plate 32 is fixedly connected to each sliding sleeve 31. A lead screw nut 33 is fixedly connected to each slide plate 32. A lead screw 34 is connected to each lead screw nut 33. The lead screw 34 is fixedly connected to the output shaft of the second motor 35. The lead screw 34 is rotatably connected to the upper support frame 24. The second motor 35 is fixedly connected to the upper support frame 24. When the second motor 35 is started, it drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the lead screw nut 33 to slide the slide plate 32 and the sliding sleeve 31 on the slide rail 25, thereby enabling the position adjustment of the two slide plates 32.

[0034] The lifting mechanism includes a cylinder bracket 51 fixedly connected to the slide plate 32, a cylinder 52 fixedly connected to the cylinder bracket 51, and a lifting sleeve 53 fixedly connected to the cylinder rod of the cylinder 52; by starting the cylinder 52, the cylinder rod of the cylinder 52 drives the lifting sleeve 53 to rise and fall.

[0035] The rotary mechanism includes a stabilizing sleeve 41 fixedly connected to the lifting sleeve 53. A third motor 43 is fixedly connected to the stabilizing sleeve 41, and a plasma emitter 42 is fixedly connected to the output shaft of the third motor 43. When the lifting sleeve 53 rises and falls, it drives the stabilizing sleeve 41 to rise and fall, which in turn drives the third motor 43 to rise and fall. The output shaft of the third motor 43 drives the plasma emitter 42 to rise and fall, thereby adjusting the distance between the plasma emitter 42 and the product surface. When the third motor 43 is started, its output shaft drives the plasma emitter 42 to rotate, ensuring that the particles emitted by the plasma emitter 42 impact the surface of the object evenly and sufficiently for surface treatment.

[0036] refer to Figure 1 Detailed explanation of an embodiment where the plasma emitter head is connected to the plasma emitter:

[0037] The plasma emitter is located at the lower part of the frame 11. Two through holes 62 are machined on the outer casing 61. Each plasma emission head 42 has a conduit connected to the plasma emitter passing through its corresponding through hole 62. This allows the plasma emitter and plasma emission head 42 to communicate and emit particles to treat the surface of the object.

[0038] refer to Figures 1 to 4 Detailed examples of surface treatment for transport products:

[0039] The transport mechanism includes two pairs of mounting plates 12 fixedly connected to the upper part of the frame 11. Each pair of mounting plates 12 is fixedly connected to the other pair of mounting plates 12 via two auxiliary plates 13. A synchronous pulley 15 is rotatably connected to each pair of mounting plates 12, and the two synchronous pulleys 15 are driven by a synchronous belt 16. A first motor 17, which drives the corresponding synchronous pulley 15, is fixedly connected to one of the mounting plates 12. A support plate 21 is provided at the lower part of the synchronous belt 16. Multiple upright legs 22 are fixedly connected to the support plate 21 and are fixedly connected to the frame 11. When transporting products, the first motor 17 is started, and the output shaft of the first motor 17 drives the corresponding synchronous pulley 15 to rotate. This synchronous pulley 15, in conjunction with the other synchronous pulley 15, drives the synchronous belt 16. The product is placed on the synchronous belt 16, and the movement of the synchronous belt 16 propels the product for transport. However, the synchronous belt 16 may collapse during product transport, which is detrimental to product transport. The support plate 21 at the lower part of the synchronous belt 16 provides auxiliary support, ensuring stable transport of the product during the movement of the synchronous belt 16. The timing pulley 15 is a spur gear, and the timing belt 16 is a toothed belt, which ensures the stable movement of the timing belt 16 when the two timing pulleys 15 rotate.

[0040] refer to Figure 3 and Figure 4 Detailed explanation of an embodiment of the stabilizing motion of the timing belt 16:

[0041] Two constraint plates 14 are fixedly connected to the two pairs of mounting plates 12 to constrain the synchronous belt 16, thereby constraining both sides of the synchronous belt 16 through the two constraint plates 14, ensuring the stable transmission between the synchronous belt 16 and the two synchronous pulleys 15, and ensuring the stable movement of the synchronous belt 16 for product transportation.

[0042] refer to Figure 5 This document details an example of surface treatment of a product using two misaligned plasma emission heads 42.

[0043] Two transverse sliding mechanisms slide synchronously in opposite directions, with their sliding direction perpendicular to the direction of the product being transported by the transport mechanism. This allows the two transverse sliding mechanisms to drive two lifting mechanisms to be staggered, the two lifting mechanisms to drive two rotating mechanisms to be staggered, and the two rotating mechanisms to drive two plasma emission heads 42 to be staggered, enabling surface treatment of the upper surface of products of different widths.

[0044] refer to Figure 5 and Figure 6 A detailed example of adjusting the distance between the two plasma emission heads 42 and the product:

[0045] Two lifting mechanisms drive two rotating mechanisms to lift and lower synchronously, maintaining the same distance from the product being transported by the transport mechanism. This synchronous lifting and lowering of the two rotating mechanisms, in turn, drives the lifting and lowering of the two plasma emission heads 42. Adjusting the distance between the two plasma emission heads 42 and the transported product allows for adjustment of the surface treatment effect of the product by the two plasma emission heads 42.

[0046] refer to Figure 1 The following is a detailed description of an embodiment that guides the product to ensure it is transported to the lower part of the two plasma emission heads 42:

[0047] The transport mechanism is symmetrically equipped with a product guide mechanism for limited transport. The guide mechanism includes threaded rods threaded to the upper support frame 24, and guide bars rotatably connected to the other end of the threaded rods. This allows the feed length of the two threaded rods on both sides of the upper support frame 24 to be adjusted by rotating the two threaded rods. The position of the ends of the two threaded rods can be adjusted to adjust the position of the two guide bars. The two guide bars are inclined, with a larger distance between them on one side. After the transported product comes into contact with the two guide bars on the side with the larger distance, it gradually moves towards the center, thus gradually guiding the product to the lower part of the two plasma emission heads 42 during transport for thorough surface treatment.

[0048] refer to Figure 1 Detailed examples of embodiments of a space covering the product for surface treatment:

[0049] The outer cover 61 has detachable shielding mechanisms on both sides corresponding to the transported products. The shielding mechanisms can be double-leaf door structures that are rotatably connected to both ends of the outer cover 61, which can shield the upper space. At the bottom of the door structure, there can be a curtain structure fixed to the upper side of the outer cover 61, which can both shield suspended objects and not affect the transport of products. Thus, the size of the space covered by the outer cover 61 can be controlled by installing and removing the shielding mechanisms, and the connection area between the surface treatment space and the external space can be controlled. This can reduce the connectivity between the internal space and the external space of the outer cover 61, so that oil and heat can be fully discharged under the action of the exhaust pipe 63 and the exhaust mechanism.

[0050] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
