Description

Technical Field

[0001] The present application relates to the technical field of optical parts processing equipment, and more specifically, to a coating vacuum chamber cleaning device and a coating equipment. Background Art

[0002] In the processing of optical parts, coating equipment is usually used for surface coating. Before placing the optical lens in the coating vacuum chamber of the coating equipment for coating, the coating vacuum chamber needs to be cleaned. The existing cleaning process usually involves manually cleaning the coating vacuum chamber with a vacuum cleaner. Due to the complex structure and numerous components in the coating vacuum chamber, and the small size of the gaps between the components that are not easily sucked by the vacuum cleaner head, the existing larger vacuum cleaner heads cannot clean properly, so that the residual film material particles and the fragments of film layer deposition will affect the next coating and affect the quality of the next coating, such as the finish.

[0003] Therefore, when the coating vacuum chamber of a conventional coating machine is cleaned, the residual film material particles and the fragments of film layer deposition are manually adsorbed by a vacuum cleaner, which may lead to incomplete cleaning and affect the coating quality of the product.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0005] The purpose of the present application is to provide a coating vacuum chamber cleaning device and a coating equipment, which solves the problem in the prior art that when cleaning the coating vacuum chamber, manual suction with a vacuum cleaner may result in incomplete cleaning and affect the coating quality of the product.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0016] In an optional embodiment, a filter element is provided in the dust collector, and the filter element is used to filter the dust that is absorbed by the negative pressure of the handheld vacuum cleaner, so that the filtered wind flows back from the air intake port to the blowing and suction mechanism.

[0017] In an optional embodiment, the coating vacuum chamber cleaning device further includes a partition grid, which is used to be arranged in the coating vacuum chamber and to divide the coating vacuum chamber into a plurality of sub-chambers.

[0018] In an optional embodiment, the blowing and suction mechanism includes a vortex fan, and the blowing port and the suction port are both arranged on the vortex fan.

In addition, by connecting the dust blower and the handheld vacuum cleaner to the blowing port and the suction port of the blowing and suction mechanism respectively, the integrity of the structure is improved, and it is more convenient to use with the coating equipment body, so that the coating vacuum chamber can be cleaned quickly and thoroughly, achieving a clean and tidy effect, greatly reducing the impact of unclean cleaning on the quality of the next coating.

[0030] Embodiment 1

[0031] See also Figure 1 , Figure 2 The present embodiment provides a coating vacuum chamber cleaning device, which is used to clean and dust the coating vacuum chamber 500 in the coating equipment body in a timely manner. The coating vacuum chamber cleaning device mainly includes: a blowing and suction mechanism 100, a dust blower 200 and a handheld dust suction unit 300. The blowing and suction mechanism 100 has a blowing port 110 for blowing out gas and a suction port 120 for generating negative pressure. The blowing and suction mechanism 100 is turned on after being powered on, and air is blown from the blowing port 110, and negative pressure is generated by sucking air from the suction port 120. The dust blower 200 is connected to the blowing port 110 and is used to blow air into the coating vacuum chamber 500. The air with positive pressure blown out from the blowing port 110 is ejected through the dust blower 200, so that small gaps between components or grooves in the coating vacuum chamber 500 that are not easily sucked can be blown, thereby blowing impurities out of the gaps or grooves for easy cleaning. The handheld vacuum cleaner 300 is connected to the air inlet 120 and is held by hand to enter the coating vacuum chamber 500 for vacuuming. The negative pressure in the air inlet 120 generates suction through the handheld vacuum cleaner 300, and the handheld vacuum cleaner 300 can be manually moved into the coating vacuum chamber 500 to suck away impurities blown out of small gaps and small grooves to achieve the purpose of cleaning.

[0032] See also Figure 1In this embodiment, a coating vacuum chamber cleaning device is provided with a dust blower 200 to blow air into the coating vacuum chamber 500, so that impurities (residual film material particles, fragments of film layer deposition, etc.) in the gaps in the coating vacuum chamber 500 or the gaps between the components can be blown out to form smaller gaps. Since the handheld vacuum unit 300 is handheld to enter the coating vacuum chamber 500 for vacuuming, the impurities blown out of the gaps can be easily sucked by the handheld vacuum unit 300, so that the interior of the coating vacuum chamber 500 can be cleaned without leaving any residue in the gaps. Through the cooperation of the dust blower 200 and the handheld vacuum unit 300, it can be handheld and placed in a gap that is difficult to clean. The dust blower 200 blows air while the handheld integrator vacuums, so that the dust collection is efficient and clean. In addition, by respectively connecting the dust blower 200 and the handheld dust suction unit 300 to the blowing port 110 and the suction port 120 of the blowing and suction mechanism 100, the integrity of the structure is improved, and it is more convenient to use with the coating equipment body, so that the coating vacuum chamber 500 can be cleaned quickly and thoroughly, achieving a clean and tidy effect, greatly reducing the impact of unclean cleaning on the quality of the next coating.

[0033] See also Figure 1 The blowing and suction mechanism 100 in this embodiment includes a vortex fan 130, and the vortex fan 130 can be a high-pressure vortex fan 130. The pressure of the high-pressure vortex fan 130 is generally between 10KPA and 100KPA. The high-pressure fan rotates through the impeller. Due to the centrifugal force, the wind vane causes the gas to move forward and outward, thereby forming a series of spiral movements. The air between the impeller blades accelerates the rotation in a spiral shape and squeezes the gas outside the pump body into the channel (sucked in by the air intake port 120). After it enters the channel, the gas is compressed, and then returns to the impeller blades to accelerate again, which has the advantage of high pressure of the blown air. The blowing port 110 and the air intake port 120 are both arranged on the vortex fan 130; in this way, the functions of suction and blowing can be realized through a high-pressure vortex fan 130, with high integration and optimized structure to improve practicality.

[0034] See also Figure 1 Furthermore, the air pressure of the air inlet 120 is lower than the air pressure of the air outlet 110; thus, the air outlet 110 blows out high-pressure gas, so that wind with a relatively high air pressure can be blown out from the dust blower 200, which is convenient for blowing out impurities that are not easy to blow out in the gap, thereby ensuring the suction and dust removal effect. The negative pressure in the air inlet 120 can be low pressure, so that the handheld dust suction unit 300 generates a relatively small suction force, and the pressure of the air inlet 120 is small, so that the suction force generated by the handheld dust suction unit 300 is small, which is easy to control. It is avoided that the inner wall of the coating vacuum chamber 500 is easily sucked due to excessive suction.

[0035] See also Figure 1The high-pressure air blowing port 110 in the high-pressure turbine blower is connected to the hand-held dust blower 200 via a pipe, and the hand-held dust suction unit 300 is connected to the dust collector 430 via another pipe. The dust collector 430 is then connected to the air suction port 120 in the high-pressure turbine blower. The hand-held dust blower 200 blows out the dust in the gap through the high-pressure air blowing port 110, and then the hand-held dust suction unit 300 performs dust suction, and the sucked impurities are sucked into the dust collector 430 for collection, completing the cleaning process.

[0036] See also Figure 1 Furthermore, the dust blower 200 in this embodiment is provided with a handheld handle 210 to form a handheld vacuum cleaner. The handheld handle 210 makes it easy for the user to hold the vacuum cleaner, so that the user can accurately blow dust into grooves or gaps that are difficult to handle, leaving no dead corners for residue. The handheld handle 210 makes it easy to hold, and when used together with the handheld vacuum cleaner 300, the user can hold the handheld vacuum cleaner in one hand and the handheld vacuum cleaner 300 in the other hand, and the two can work together to achieve better cleaning effects and more convenient operation.

[0037] See also Figure 1 Further, the dust blower 200 in this embodiment is connected to the air outlet 110 through the first flexible pipe 400. The first flexible pipe 400 can be a high-pressure flexible pipe, one end of which is connected to the air outlet 110 through a joint, and the other end is connected to the dust blower 200 through a joint. The handheld dust suction unit 300 is connected to the air inlet 120 through the second flexible pipe 410. The second flexible pipe 410 can be a low-pressure flexible pipe that can be divided into two parts. One end of the first part is connected to the handheld dust suction unit 300 through a joint, and the other end is connected to the dust collector 430 through a joint; one end of the second part is connected to the dust collector 430 through a joint, and the other end is connected to the air inlet 120 through a joint. The use of a flexible pipe is convenient for timely dragging when handheld use, so that the dust blower 200 and the handheld dust suction unit 300 can be moved to any position in the coating vacuum chamber 500 as needed. It is greatly convenient for users to use.

[0038] See also Figure 1Furthermore, a high-low pressure combined flexible pipe 420 is sleeved on the outer side of the first flexible pipe 400 and the second flexible pipe 410. Since the low-pressure flexible pipe and the high-pressure flexible pipe are two independent pipes, the two pipes are easily entangled and messy if placed randomly, making the tooling environment messy. The high-low pressure combined flexible pipe 420 is sleeved on the middle section of the first flexible pipe 400 and the second flexible pipe 410, and the first flexible pipe 400 and the second flexible pipe 410 are only bundled and restrained in a certain area. The high-low pressure combined flexible pipe 420 sleeves the first flexible pipe 400 and the second flexible pipe 410 together, which not only does not affect the use position, making the entire cleaning device tidy and not messy, but also protects the flexible pipe from being damaged, playing a safety role.

[0039] See also Figure 1 Furthermore, in the present embodiment, a filter element 431 is provided in the dust collector 430, and the filter element 431 is used to filter the dust that blocks the negative pressure absorption of the hand-held dust collection part 300, so that the filtered wind flows back from the air inlet 120 to the blowing and suction mechanism 100. The dust collector 430 adopts a high-efficiency dust collector 430, and a filter element 431 is provided in its inner cavity. After the dust collected by the hand-held dust collection part 300 is collected to the high-efficiency dust collector 430 via the second flexible duct 410, it is filtered and blocked in the high-efficiency dust collector 430 by the filter element 431, and the negative pressure wind filtered by the filter element 431 from the high-efficiency dust collector 430 flows back from the air inlet 120 to the blowing and suction mechanism 100.

[0040] See also Figure 1 , Figure 2 Furthermore, the coating vacuum chamber cleaning device in this embodiment further includes a partitioning grid 510, which is used to be arranged in the coating vacuum chamber 500 and is used to divide the coating vacuum chamber 500 into a plurality of sub-chambers. Before dust removal and cleaning, the coating vacuum chamber 500 can be divided into a plurality of sub-areas by the partitioning grid 510, and then the space in each sub-area is dusted respectively. When blowing, the impurities blown up are not easy to run into other partitions, which is convenient for cleaning, and the partitioned collection reduces the space and is more conducive to improving the collection efficiency.

[0041] There are many ways to set the partition grid 510. For example, it can be pre-set in the coating vacuum chamber 500. When coating, the partition grid 510 is not needed. The partition grid 510 is in a folded state and does not affect the normal coating process. It can be unfolded when cleaning is needed. For example, it can be a separately set accessory for the coating vacuum chamber 500. When film is applied, it can be directly installed in the coating vacuum chamber 500 for use.

[0042] Embodiment 2

[0043] See also Figure 1 , Figure 2 This embodiment proposes a coating device, which includes a coating device body and the coating vacuum chamber cleaning device as described above; the coating device body is provided with a coating vacuum chamber 500, and the coating vacuum chamber cleaning device is used to remove dust from the coating vacuum chamber 500.

[0044] The coating equipment provided in this embodiment has a hand-held dust blower 200. By setting the hand-held dust blower 200 to blow air toward the coating vacuum chamber 500, the gaps in the coating vacuum chamber 500 or the impurities in the gaps between the components (residual film material particles, fragments of film layer deposition, etc.) can be blown out in a targeted manner to blow out smaller gaps. And the hand-held dust suction unit 300 is hand-held to enter the coating vacuum chamber 500 for dust suction, so that the impurities blown out of the gaps can be easily sucked by the hand-held dust suction unit 300. The two are used in combination, so that the coating vacuum chamber 500 can be cleaned and no residue is left in the gaps. And it has better structural integrity and is more convenient to use with the coating equipment body, so that the coating vacuum chamber 500 can be cleaned quickly and thoroughly, achieving a clean and tidy effect, greatly reducing the impact of unclean cleaning on the quality of the next coating.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
