[0025] During the production of precision optical lenses, such as contact lenses, dust particles and debris often adhere to the lenses and lens molds. To remove dust particles from the lenses and lens molds, electrostatic dust removal devices are currently commonly used. These devices utilize the principle of electrostatic adsorption to remove particulate contaminants from the lens surface, ensuring product cleanliness and quality. Conventional technology typically involves workers manually placing the molds containing the lenses into an electrostatic box 102 for processing. This process is inefficient and labor-intensive, hindering production costs.

[0026] In order to solve the above technical problems, an embodiment of the present application provides an electrostatic dust removal device.

[0027] Reference Figure 1 、 Figure 2 As shown, an embodiment of the present application provides an electrostatic dust removal device, including a transfer assembly 100, a first loading platform 101, an electrostatic box 102 and a second loading platform 103; the first loading platform 101, the electrostatic box 102 and the second loading platform 103 are arranged in sequence along a straight line, and the transfer assembly 100 is provided with a transfer portion 116 driven to move along an arrangement path 104; the transfer portion 116 absorbs the mold placed on the first loading platform 101 through negative pressure; an opening 105 is provided on the electrostatic box 102; the transfer portion 116 is driven to move to a position corresponding to the opening 105, the transfer portion 116 is driven close to the opening 105, and the mold passes through the opening 105 into the electrostatic box 102; after the mold is dusted in the electrostatic box 102, the transfer portion 116 is driven to drive the mold out of the opening 105, the transfer portion 116 moves along the arrangement path 104 to a position corresponding to the second loading platform 103, and the mold is placed on the second loading platform 103.

[0028] The electrostatic precipitator provided in the embodiment of the present application includes a transfer assembly 100 , a first loading platform 101 , an electrostatic box 102 and a second loading platform 103 .

[0029] It should be noted that both the first loading platform 101 and the second loading platform 103 have a structure for holding the mold. The specific structures of the first loading platform 101 and the second loading platform 103 are not particularly limited here, and those skilled in the art can select them according to their needs.

[0030] Taking contact lens production as an example, the transfer unit 116, in conjunction with the first loading platform 101, is used to separate the female and male molds of a contact lens mold. With the lens attached to the female mold, the transfer unit 116 uses negative pressure to suck the female mold and lens apart, separating them. The transfer unit 116 then simultaneously places the female mold and lens into the electrostatic chamber 102 for dust removal.

[0031] The transfer assembly 100 can grab the mold on the first loading platform 101 and transfer it to the electrostatic box 102 for electrostatic dust removal. The treated mold in the electrostatic box 102 is then transferred to the second loading platform 103. It should be noted that the mold can also be transferred to the first loading platform 101 for further placement as needed.

[0032] The first loading platform 101, the electrostatic box 102 and the second loading platform 103 of the embodiment of the present application are arranged in sequence along a straight line, and the transfer component 100 is provided with a transfer part 116 driven to move along the arrangement path 104; the transfer part 116 of the embodiment of the present application absorbs the mold placed on the first loading platform 101 through negative pressure, that is, the embodiment of the present application can grab the mold through the transfer part 116.

[0033] It should be noted that, in the embodiment of the present application, the first loading platform 101, the electrostatic box 102 and the second loading platform 103 are arranged in sequence along a straight line, and the electrostatic box 102 is arranged between the first loading platform 101 and the second loading platform 103. The transfer component 100 can drive the transfer part 116 to move linearly on the arrangement path 104, and travel back and forth between the first loading platform 101, the second loading platform 103 and the electrostatic box 102.

[0034] The electrostatic box 102 of the embodiment of the present application is provided with an opening 105; the transfer unit 116 is driven to move to a position corresponding to the opening 105, the transfer unit 116 is driven close to the opening 105, and the mold is passed through the opening 105 into the electrostatic box 102; after the mold undergoes dust removal treatment in the electrostatic box 102, the transfer unit 116 is driven to drive the mold out of the opening 105, and the transfer unit 116 moves along the arrangement path 104 to a position corresponding to the second loading platform 103, and places the mold on the second loading platform 103. The embodiment of the present application can grasp or place the mold on the first loading platform 101 or the second loading platform 103 by moving the transfer unit 116 along the arrangement path 104, and make the mold undergo electrostatic dust removal treatment in the electrostatic box 102.

[0035] It should be noted that the specific shape of the electrostatic box 102 can be set by those skilled in the art as needed. For example, the electrostatic box 102 is in the shape of a rectangular box or a cylinder.

[0036] Among them, the electrostatic box 102 uses a high-voltage direct current electric field to ionize and decompose the neutral gas molecules in the air to produce a large number of positive and negative ions, which move toward the two poles under the action of the electric field force. During the movement, they encounter the mold and the dust particles in the mold. The positive and negative ions can combine with the dust particles with their own positive and negative charges to capture the dust particles.

[0037] Compared with the existing technology, the embodiments of the present application can realize automatic transfer and automatic electrostatic treatment, effectively improve work efficiency, reduce the workload of staff, reduce production costs, ensure that the lenses are contaminated, and improve product yield.

[0038] Further, refer to Figure 2 As shown, the transfer assembly 100 includes a slide rail 106, a mounting plate 107 and a drive mechanism 108; the arrangement direction of the slide rail 106 is parallel to the arrangement path 104, and the mounting plate 107 is connected to a slider arranged on the slide rail 106; the drive mechanism 108 is used to drive the mounting plate 107 to move along the arrangement direction of the slide rail 106; a telescopic rod 109 is provided on the mounting plate 107, whose telescopic direction is perpendicular to the plane where the opening 105 is located, and the transfer part 116 is installed at the telescopic end of the telescopic rod 109.

[0039] It should be noted that the arrangement direction of the slide rail 106 is parallel to the arrangement path 104 . When the arrangement path 104 extends horizontally, the slide rail 106 can be horizontally arranged above the arrangement path 104 .

[0040] Exemplarily, the transfer assembly may also be a guide rod and a linear bearing seat, or may slide in a guide groove.

[0041] The telescopic rod 109 can be a telescopic cylinder. The telescopic direction of the telescopic rod 109 is perpendicular to the plane where the opening 105 is located, that is, when the plane where the opening 105 is located is horizontally arranged, the telescopic direction of the telescopic rod 109 is then vertically arranged.

[0042] It should be noted that the specific structure of the driving mechanism 108 is not limited in the embodiment of the present application, and those skilled in the art can configure it as needed.

[0043] Exemplarily, the driving mechanism 108 includes a driving motor and a roller screw connected to a power output end of the driving motor.

[0044] For example, the driving mechanism 108 may be a chain transmission mechanism, which drives the mounting plate 107 to slide linearly.

[0045] For example, the driving mechanism 108 may also be a linear motor or a telescopic cylinder.

[0046] Reference Figure 3 As shown, as an optional embodiment, the electrostatic box 102 is provided with an air inlet 110 and an exhaust port 111; the air inlet 110 is connected to an air filter 112, and under the action of negative pressure, the air passes through the air filter 112 and the air inlet 110 in sequence and enters the electrostatic box 102, and the electrostatic box 102 is provided with a static elimination rod for releasing a high-voltage electric field to ionize air molecules, and the exhaust port 111 is connected to an exhaust pump for discharging gas or particulate matter in the electrostatic box 102.

[0047] Furthermore, the electrostatic box 102 of the embodiment of the present application is a rectangular box body; an air inlet 110 and an exhaust port 111 are provided on the rectangular box body. By connecting an air filter 112 to the air inlet 110, the air entering the electrostatic box 102 is filtered to prevent dust and other particulate matter in the air from entering the interior of the electrostatic box 102.

[0048] Reference Figure 3 As shown, the electrostatic box 102 is arranged horizontally, the plane where the opening 105 is located is the top surface of the electrostatic box 102, and the first plane 113 is the bottom surface of the electrostatic box 102. The exhaust port 111 is arranged on the first plane 113 of the electrostatic box 102, and the air inlet 110 is arranged on the second plane 114 of the electrostatic box 102. The first plane 113 and the second plane 114 intersect vertically.

[0049] The static eliminator is a direct application of existing technology. Its needle tip releases a high-voltage electric field and blows air, ionizing air molecules and evenly dispersing the resulting large number of positive and negative ions throughout the cavity. These ions then come into contact with the dust on the mold. Because dust particles are positively or negatively charged, the released positive and negative ions neutralize the dust's charge, drawing the dust from the mold surface. The exhaust port 111 at the bottom of the static box 102 is connected to an air pump, allowing the airborne dust and debris from the separation of the master and male molds to be extracted and removed from the bottom.

[0050] It should be noted that the electrostatic box 102 can be arranged horizontally or vertically as needed. When the electrostatic box 102 is arranged horizontally, a plurality of exhaust ports 111 can be provided on the bottom surface.

[0051] Reference Figure 3 As shown, illustratively, two exhaust ports 111 are opened on the bottom surface and arranged at intervals.

[0052] It should be noted that the first plane 113, on which the exhaust port 111 is located, and the second plane 114, on which the air inlet 110 is located, can also be arranged parallel to each other. Those skilled in the art can adjust this arrangement as needed. The first plane 113 and the second plane 114 are parallel and spaced apart, meaning that the air inlet 110 is located at one end of the electrostatic box 102 and the exhaust port 111 is located at the other end of the electrostatic box 102.

[0053] As an optional embodiment, there are multiple openings 105 on the electrostatic box 102, and the multiple openings 105 are arranged at intervals on the surface of the electrostatic box 102.

[0054] For example, refer to Figure 2 As shown, the electrostatic box 102 has two openings 105 .

[0055] As an optional embodiment, the transfer portion 116 is a suction cup, which is provided with a sealing member 115 that can contact the plane where the opening 105 is located, and the orthographic projection of the sealing member 115 on the plane where the opening 105 is located covers the opening 105 .

[0056] It should be noted that the suction cup is connected to the negative pressure device through a connecting pipe, so the suction cup can generate negative pressure suction to grab the mold.

[0057] Furthermore, in the embodiment of the present application, a sealing member 115 is provided on the suction cup. When the suction cup grasps the mold and enters the opening 105 , the sealing member 115 seals the opening 105 of the electrostatic box 102 , thereby closing the opening 105 .

[0058] Therefore, when the mold is subjected to electrostatic treatment in the embodiment of the present application, the opening 105 can be sealed to prevent particles from entering the opening 105 and ensure that the gas can be discharged through the exhaust port 111, thereby effectively improving the efficiency of the automated electrostatic treatment.

[0059] As an optional embodiment, the first loading platform 101, the electrostatic box 102, and the second loading platform 103 are arranged in sequence along a horizontal straight line; the transfer assembly 100 is positioned above the horizontal line. If desired, the height of the transfer assembly 100 can also be set flush with the arrangement path 104 to make the entire device layout more compact and reduce the overall size of the device.

[0060] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
