Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spraying technology, specifically relating to a protective device for preventing spraying powder from flying. Background Technology
[0002] Currently, most sheet metal parts in the hardware industry require spraying or powder coating processes to prevent rust and corrosion.
[0003] However, for some sheet metal parts such as chassis and enclosures that require internal electrical conduction, such as grounding protection or circuit board anti-static protection, it is necessary to leave the surface of the local electrical conduction area blank to prevent paint or powder coating. Therefore, before the spraying or powder coating process, it is necessary to manually apply protective tape to the unpainted areas. After spraying, the protective tape is peeled off one by one. This method is slow and cannot improve work efficiency. In addition, the protective tape is for single use, which results in a significant cost.
[0004] In addition, for some sheet metal parts with bulges and bridge-shaped protrusions, after applying protective tape to these parts, the protective tape is prone to problems such as falling off and popping up, resulting in gaps. During the spraying operation, powder overflow is likely to occur, making it impossible to ensure the quality of the spraying operation. Utility Model Content
[0005] To address the shortcomings of the existing technology, this utility model provides a protective device for preventing spray powder from flying out of the sprayer, thereby improving spraying efficiency, effectively saving costs, and ensuring the quality of spraying operations.
[0006] The technical objective of this utility model is achieved through the following technical solution:
[0007] This utility model provides a protective device for preventing spray powder from flying out of the coating, including a base and a cover plate;
[0008] The base is a seat with an opening, and the bottom of the base is provided with multiple clamping structures for clamping the workpiece.
[0009] The cover plate is placed over the opening, and the cover plate has a spray nozzle corresponding to the surface of the workpiece to be sprayed.
[0010] In some implementations, the clamping structure includes a fixing member and a clamping member arranged facing each other;
[0011] The fixing member has a receiving groove at one end facing the clamping member. The workpiece is clamped between the receiving groove and the clamping member to achieve the positioning and clamping of the workpiece, ensuring that the workpiece will not move during the spraying operation, thus ensuring the quality of the spraying operation.
[0012] In some implementations, a bevel is formed on the edge of the receiving groove near one end of the clamping member. The bevel facilitates the loading and positioning of the workpiece and prevents damage to the workpiece surface or injury to the operator due to sharp corners on the receiving groove.
[0013] In some implementations, the clamping element is an arc-shaped spring sheet, which has a relatively balanced clamping effect, ensuring the positioning and clamping effect of the workpiece.
[0014] In some implementations, the two ends of the arc-shaped spring are used to contact the workpiece to ensure a relatively balanced clamping effect on the workpiece. At the same time, the gap between the two ends can also avoid protrusions or bumps on the workpiece.
[0015] In some implementations, the clamping structure is detachably mounted on the bottom of the base, and the clamping structure can be disassembled and replaced according to different models and sizes of workpieces to improve the versatility of the protective device.
[0016] Some implementations also include a protective layer;
[0017] The protective layer covers the upper surface of the cover plate, and a protective opening is formed in the protective layer corresponding to the position of the spray nozzle. A folded edge is formed at the edge of the protective opening, which protrudes from the edge of the spray nozzle. The folded edge can better seal and protect the edge of the surface to be sprayed on the workpiece, and better avoid powder overflow.
[0018] In some implementations, the protective layer is an elastic adhesive layer, which can effectively provide a sealing effect.
[0019] In some implementations, the gap between the edge of the workpiece and the edge of the spray nozzle is smaller than the width of the folded edge protruding from the edge of the spray nozzle, ensuring that the folded edge provides a better sealing and protective effect.
[0020] In some implementations, the gap between the edge of the workpiece and the edge of the spray nozzle is 0.3-0.5mm, and the width of the folded edge protruding from the edge of the spray nozzle is 0.8-1.0mm, ensuring that the folded edge provides a good sealing and protective effect.
[0021] In summary, this utility model has at least the following advantages:
[0022] This utility model provides a protective device for preventing spray powder from flying out of the workpiece. By setting multiple clamping structures at the bottom of the base to clamp the workpiece, the workpiece is accurately positioned so that the surface to be sprayed is aligned with the spray nozzle on the cover plate, while other surfaces that do not need to be sprayed are located below the cover plate. This allows for simultaneous spray protection of multiple workpieces, improving the efficiency of the spraying operation. Compared with the traditional method of applying protective tape, it has the advantage of saving costs. At the same time, it also provides good protection for surfaces that do not need to be sprayed, effectively ensuring the quality of the spraying operation. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0034] Example 1:
[0035] Please see Figure 1 and Figure 2 A protective device for preventing spray powder from flying out, comprising a base 100 and a cover plate 200.
[0036] The base 100 is used to fix and support other components, and also facilitates the handling and movement of the protective device. For example, the base 100 is a seat with an opening. The bottom of the base 100 is provided with multiple clamping structures 300 for clamping workpieces. The opening on the base 100 is set relative to the bottom of the base 100. Thus, when clamping the workpiece to the clamping structure 300, the workpiece can be inserted from the opening of the base 100 and clamped at the clamping structure 300 at the bottom.
[0037] There are multiple clamping structures 300, which can be used to correspond one-to-one with multiple workpieces. That is, the base 100 can carry multiple workpieces at one time, and multiple workpieces can be clamped one by one by multiple clamping structures 300 to fix the position of the workpieces.
[0038] Here, there are no specific restrictions on the number or arrangement of the clamping structures 300. The number of clamping structures 300 can be adjusted according to the needs of the spraying operation on the production line or the needs of the workpiece output. The arrangement of the clamping structures 300 can be combined with the shape of the workpiece, and can be arranged in a uniformly spaced manner or in a circular manner. For example, in this embodiment, a multi-row and multi-column uniformly spaced arrangement is adopted.
[0039] The cover plate 200 is placed over the opening. Here, a positioning post can be set at the edge of the opening, and a positioning hole can be set on the cover plate 200 at the position corresponding to the positioning post. By utilizing the correspondence between the positioning post and the positioning hole, the cover plate 200 can be quickly positioned and placed on the base 100. Of course, the positioning hole can also be set at the edge of the opening, and the positioning post can be set on the cover plate 200 at the position corresponding to the positioning hole, etc., as long as the function of quick positioning is achieved.
[0040] The cover plate 200 has a spray nozzle 210, which corresponds to the surface of the workpiece to be sprayed. For example, in one example, the workpiece is a cuboid structure, including an upper surface, a lower surface, and four sides. The upper surface is the surface to be sprayed. Before the spraying operation, the lower surface of the workpiece is placed into the base 100 with the opening of the base 100 facing it, so that the four sides of the workpiece are clamped by the clamping structure 300. When the clamping and positioning are completed, the upper surface of the workpiece, i.e. the surface to be sprayed, faces the opening. At this time, the cover plate 200 is placed over the opening of the base 100, and the spray nozzle 210 on the cover plate 200 corresponds to the surface of the workpiece to be sprayed, i.e., the surface of the workpiece to be sprayed is exposed, while the sides of the workpiece are located between the cover plate 200 and the base 100, and are in a non-exposed state.
[0041] With the edge of the spray nozzle 210 and the edge of the surface to be sprayed sealed, no powder overflow can be ensured during the spraying operation. Since there is no gap between the spray nozzle 210 and the surface to be sprayed, no powder will fall into the base 100, which means it will not affect other sides of the workpiece or the perimeter that does not need to be sprayed, thus ensuring the quality of the spraying operation.
[0042] Understandably, the number of spray nozzles 210 on the cover plate 200 matches the number of workpieces, and the shape of the spray nozzles 210 matches the shape of the surface to be sprayed on the workpiece, so as to ensure that the spraying requirements and spraying quality of the workpieces are met.
[0043] In the specific operation process, the workpieces are first clamped one by one in each clamping structure 300. After the clamping structure 300 plays a stable positioning and clamping role for the workpieces, the cover plate 200 is placed on the opening of the base 100. Then, multiple workpieces are sprayed. After the spraying operation is completed, the cover plate 200 is removed and the workpieces are taken out one by one.
[0044] This embodiment provides a protective device for preventing spray powder from flying out of the workpiece. By setting multiple clamping structures 300 at the bottom of the base 100 to clamp the workpiece, the workpiece is accurately positioned so that the surface of the workpiece to be sprayed is relative to the spray nozzle 210 on the cover plate 200, while other surfaces that do not need to be sprayed are located below the cover plate 200. This achieves the function of spraying and protecting multiple workpieces at one time, improving the efficiency of the spraying operation. Compared with the traditional method of applying protective tape, it has the advantage of saving costs. At the same time, it also provides good protection for surfaces that do not need to be sprayed, effectively ensuring the quality of the spraying operation.
[0045] Example 2:
[0046] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the protective device of this utility model. Please refer to [link / reference]. Figure 3 .
[0047] In this embodiment, the clamping structure 300 includes a fixing member 310 and a clamping member 320 arranged opposite to each other. There is a gap between the fixing member 310 and the clamping member 320 so that the workpiece can be placed between the fixing member 310 and the clamping member 320 to provide positioning and clamping for the workpiece, and also to facilitate the removal of the workpiece.
[0048] The end of the fixing member 310 facing the clamping member 320 has a receiving groove 311. The workpiece is clamped between the receiving groove 311 and the clamping member 320. It can be understood that the structure formed by the wall surface in contact with the workpiece in the receiving groove 311 matches the structure in which the workpiece is placed in the receiving groove 311, so that the receiving groove 311 can play an accurate positioning role, and the clamping member 320 can clamp the workpiece to ensure that the workpiece will not move during the spraying operation, so as to ensure the quality of the spraying operation.
[0049] Furthermore, a bevel 312 is formed on the edge of the receiving groove 311 near the clamping member 320. The bevel 312 is designed to facilitate the loading and positioning of the workpiece, and to prevent damage to the workpiece surface or injury to the operator due to the presence of sharp corners on the receiving groove 311.
[0050] For example, the receiving groove 311 includes an upwardly formed upper inlet and a side-formed lateral inlet. The upper inlet faces the opening direction of the base 100, and the lateral inlet faces the clamping member 320. When positioning a workpiece, the workpiece can be placed into the receiving groove 311 through the upper inlet, while the lateral inlet facilitates the clamping member 320 to push the workpiece for clamping and positioning in that direction. Here, the inclined surface 312 is formed at the edge of the lateral inlet, which can avoid problems such as workpiece damage or personnel injury caused by sharp corner structures when the operator loads or removes the workpiece.
[0051] Furthermore, the clamping element 320 is an arc-shaped spring, which has a relatively balanced clamping effect, ensuring the positioning and clamping effect on the workpiece.
[0052] Specifically, the two ends of the arc-shaped spring are used to contact the workpiece. The two ends can ensure a relatively balanced clamping effect on the workpiece, and the gap between the two ends can also avoid protrusions or bumps on the workpiece.
[0053] In some embodiments, the clamping structure 300 is detachably disposed at the bottom of the base 100, and the clamping structure 300 can be disassembled and replaced according to different models and sizes of workpieces to improve the versatility of the protective device.
[0054] For example, a detachable connection method such as screws or alignment clips can be used to establish a stable connection between the clamping structure 300 and the base 100, ensuring the stability of the clamping structure 300 during operation. At the same time, the detachable connection method can be used to disassemble, replace or adjust the position of the clamping structure 300.
[0055] Example 3:
[0056] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the protective device of this utility model. Please refer to [link / reference]. Figures 4-6 .
[0057] In this embodiment, the protective device further includes a protective layer 400, which covers the upper surface of the cover plate 200. The protective layer 400 has a protective opening 410 at the position corresponding to the spray nozzle 210. A folded edge 420 that can be folded up and down is formed at the edge of the protective opening 410. The folded edge 420 protrudes from the edge of the spray nozzle 210. The folded edge 420 can better seal and protect the edge of the surface to be sprayed on the workpiece, and better avoid powder overflow.
[0058] Since the folded edge 420 protrudes from the edge of the spray nozzle 210, when the cover plate 200 is placed over the opening of the base 100, the folded edge 420 will be squeezed by the edge of the surface to be sprayed on the workpiece, thereby producing an upward or downward folding effect. This also seals the gap between the edge of the surface to be sprayed and the edge of the spray nozzle 210, completely preventing powder from falling into the base 100.
[0059] Furthermore, the protective layer 400 is an elastic adhesive layer. Because the elastic adhesive layer is elastic or flexible, it will deform itself when subjected to compression, without causing damage to the workpiece through hard contact. In this way, while ensuring a good sealing effect, the quality of the workpiece can also be ensured.
[0060] The protective layer 400 can be made of an elastic sealant made primarily of silicone, which is applied to the upper surface of the cover plate 200 and has an elastic effect after curing.
[0061] Furthermore, the gap between the edge of the workpiece and the edge of the spray nozzle 210 is smaller than the width of the folded edge 420 protruding from the edge of the spray nozzle 210, ensuring that the folded edge 420 provides a better sealing and protective effect.
[0062] Since the gap between the edge of the workpiece and the edge of the spray nozzle 210 is smaller than the width of the folded edge 420 protruding from the edge of the spray nozzle 210, after the cover plate 200 is placed over the opening of the base 100, the edge of the folded edge 420 protruding from the edge of the spray nozzle 210 will be subjected to the squeezing action of the edge of the workpiece and the edge of the spray nozzle 210, resulting in deformation, which will cause it to fold upward or downward, and at the same time, it will seal the gap between the edge of the workpiece and the edge of the spray nozzle 210.
[0063] Specifically, the gap between the edge of the workpiece and the edge of the spray nozzle 210 is 0.3-0.5mm, and the width of the folded edge 420 protruding from the edge of the spray nozzle 210 is 0.8-1.0mm, ensuring that the folded edge 420 provides a good sealing and protective effect.
[0064] For example, the gap between the edge of the workpiece and the edge of the spray nozzle 210 is 0.5mm, and the width of the folded edge 420 protruding from the edge of the spray nozzle 210 is 1.0mm.
[0065] This utility model provides a protective device for preventing spray powder from flying out of the workpiece. By setting multiple clamping structures at the bottom of the base to clamp the workpiece, the workpiece is accurately positioned so that the surface to be sprayed is aligned with the spray nozzle on the cover plate, while other surfaces that do not need to be sprayed are located below the cover plate. This allows for simultaneous spray protection of multiple workpieces, improving the efficiency of the spraying operation. Compared with the traditional method of applying protective tape, it has the advantage of saving costs. At the same time, it also provides good protection for surfaces that do not need to be sprayed, effectively ensuring the quality of the spraying operation.
