[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of these features.

[0036] Moreover, the technical solutions between the various embodiments of the present invention can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] The present invention provides a dust-free processing tool 1. In one embodiment, Figure 1 and Figure 2As shown, the dust-free processing jig 1 includes a positioning mechanism 11 and an air suction mechanism 12, the positioning mechanism 11 includes a pressing component 111, the pressing component 111 includes a first pressing part 1111 and a second pressing part 1112, the first pressing part 1111 is used to be sealed and connected with the second pressing part 1112, so that a accommodating space 17 for accommodating the workpiece is formed between the first pressing part 1111 and the second pressing part 1112; the first pressing part 1111 is provided with a processing port 11111, and the second pressing part 1112 is provided with an air suction port 11124. When the workpiece is located in the accommodating space 17, the accommodating space 17 is divided by the workpiece into a closed space and a circulation space, and the processing port 11111 and the air suction port 11124 are both connected to the circulation space; the suction port of the air suction mechanism 12 is arranged corresponding to the air suction port 11124.

[0038] The workpiece is placed in the accommodating space 17, and the first pressing member 1111 and the second pressing member 1112 are sealed together, preventing dust from entering the enclosed space, thereby effectively preventing dust and other foreign matter from adhering to the surface of the workpiece in the sealed space. The processing equipment processes the workpiece in the accommodating space 17 through the processing port 11111. The debris generated during the processing is sucked into the suction mechanism 12 through the air intake port 11124 through the circulation space, thereby effectively preventing the debris from being adsorbed on the surface of the workpiece in the circulation space. This ensures that the cleanliness of the workpiece surface after processing meets the standard, thereby eliminating the traditional cleaning process and reducing the processing cost of the workpiece. The workpiece can be an optical product, such as an optical lens.

[0039] It should be noted that the first pressing part 1111 and the second pressing part 1112 can be sealed together by tight fitting, or by a sealing rubber ring; wherein the contact surface of the sealing connection between the first pressing part 1111 and the second pressing part 1112 is arranged around the outside of the accommodating space 17, so that after the workpiece is placed in the accommodating space 17, the workpiece can separate the accommodating space 17 into a closed space and a circulation space.

[0040] It should also be noted that the accommodating space 17 can be formed by opening a groove for accommodating the workpiece in the first pressing part 1111, and then sealing the second pressing part 1112 and the first pressing part 1111 so that the second pressing part 1112 and the groove wall form the accommodating space 17; or the second pressing part 1112 is provided with a groove for accommodating the workpiece, or both the first pressing part 1111 and the second pressing part 1112 are provided with grooves, and the groove walls of the two grooves are spliced ​​together to form the accommodating space 17 when the first pressing part 1111 and the second pressing part 1112 are sealed and connected.

[0041] like Figures 1 to 6As shown, in one embodiment, the dust-free processing jig 1 further includes an air blowing mechanism 13, which includes an air blowing pipe that is connected to the circulation space. The air blowing mechanism 13 is configured to blow foreign matter adsorbed on the workpiece surface away from the workpiece surface. This foreign matter that has been separated from the workpiece surface moves toward the air intake 11124 along with the air flow generated by the air suction mechanism 12 within the circulation space, and is ultimately sucked into the air suction mechanism 12, thereby effectively improving the cleanliness of the workpiece surface and ensuring the appearance quality of the workpiece.

[0042] In one embodiment, there are multiple air blowing pipes, including a first air blowing pipe 131 and a second air blowing pipe 132. The first air blowing pipe 131 is connected to the first pressing member 1111, and the second air blowing pipe 132 is connected to the second pressing member 1112. By providing the first air blowing pipe 131 and the second air blowing pipe 132 to blow air at different positions of the workpiece, the cleanliness of the workpiece facing the first pressing member 1111 and the side facing the second pressing member 1112 are made nearly uniform, and the cleanliness of the workpiece surface is effectively improved.

[0043] Furthermore, in one embodiment, the opening of the first air pipe 131 is positioned directly opposite an effective surface of a workpiece, such that the direction of the airflow from the first air pipe 131 is perpendicular to the effective surface of the workpiece. Wherein, the workpiece may have multiple effective surfaces, and the first air pipe 131 is positioned directly opposite at least one effective surface of the workpiece, such that the direction of the airflow from the first air pipe 131 is perpendicular to the effective surface. Compared to a case where the angle between the airflow from the first air pipe 131 and the effective surface is an acute angle, positioning the airflow from the first air pipe 131 perpendicular to the effective surface makes it easier to blow away foreign matter from the effective surface.

[0044] According to one embodiment of the present invention, there are multiple first air blowing pipes 131. By setting up multiple first air blowing pipes 131, the area of ​​the workpiece cleaned by the first air blowing pipe 131 is increased, and the multiple first air blowing pipes 131 are arranged at intervals along the extension direction of the air suction port 11124. Compared with the multiple first air blowing pipes 131 being arranged at intervals along other directions, by arranging the multiple first air blowing pipes 131 at intervals along the extension direction of the air suction port 11124, foreign matter blown away from the workpiece by the first air blowing pipe 131 can be more easily sucked into the air suction port 11124, reducing the probability of the blown-away foreign matter being re-adsorbed on the surface of the workpiece.

[0045] In addition, in one embodiment, the extension direction of the pipe opening of the second air blowing pipe 132 is tilted toward the direction where the suction mechanism 12 is located, so that the airflow blown out from the second air blowing pipe 132 flows toward the direction close to the suction port 11124. Compared to tilting the second air blowing pipe 132 away from the suction port 11124, tilting the extension direction of the second air blowing pipe 132 toward the direction where the suction port 11124 is located allows the airflow blown out from the second air blowing pipe 132 to be sucked out of the suction port 11124 more quickly by the suction mechanism 12. This results in foreign matter blown off the workpiece surface by the airflow from the second air blowing pipe 132 being more quickly sucked into the suction mechanism 12 along with the airflow, thereby effectively reducing the chance of the blown-off foreign matter being re-adsorbed on the workpiece surface.

[0046] According to one embodiment of the present invention, the number of the second air blowing pipes 132 is multiple, and the area of ​​the workpiece cleaned by the second air blowing pipes 132 is increased by setting multiple second air blowing pipes 132; the multiple second air blowing pipes 132 are arranged at intervals along the extension direction of the suction port 11124. Compared with arranging the multiple second air blowing pipes 132 along other directions, the arrangement of arranging the multiple second air blowing pipes 132 at intervals along the extension direction of the suction port 11124 enables foreign matter blown off the surface of the workpiece by the multiple second air blowing pipes 132 to be sucked into the suction mechanism 12 faster.

[0047] Furthermore, in one embodiment, the pressure-covering assembly 111 further includes a sealing member, which is disposed between the first pressure-covering member 1111 and the second pressure-covering member 1112 to ensure a sealed connection between the first pressure-covering member 1111 and the second pressure-covering member 1112. The sealing member is disposed around the periphery of the accommodating space 17. The sealing member may be a rubber sealing ring, which is disposed between the first pressure-covering member 1111 and the second pressure-covering member 1112 to enhance the sealed connection between the first pressure-covering member 1111 and the second pressure-covering member 1112, thereby effectively preventing external dust from entering the accommodating space 17 through the sealed connection between the first pressure-covering member 1111 and the second pressure-covering member 1112. It should be noted that compared with the first sealing member 1111 and the second sealing member 1112 being sealed together through tight fitting to achieve a sealed connection, the sealing effect of the first pressure covering member 1111 and the second pressure covering member 1112 being sealed together through the sealing member is better, and external dust is less likely to enter the accommodating space 17 through the sealed connection between the first pressure covering member 1111 and the second pressure covering member 1112.

[0048] In one embodiment, the second pressing member 1112 defines a receiving groove 11121 for accommodating a workpiece, and an air inlet 11124 is disposed on the bottom wall of the receiving groove 11121. The walls of the receiving groove 11121 are used to enclose a receiving space 17 with the first pressing member 1111. The provision of the receiving groove 11121 for accommodating the workpiece also serves to position the workpiece, preventing significant movement during processing that could affect product quality. Furthermore, the provision of the receiving groove 11121 effectively prevents the workpiece from moving relative to the second pressing member 1112 during movement from the first pressing member 1111 to the second pressing member 1112, which could result in the first pressing member 1111 damaging the workpiece.

[0049] According to one embodiment of the present invention, the second pressing part 1112 is provided with a fixing groove 11123 for fixing the sealing part. The sealing part is located in the fixing groove 11123. The sealing part and the fixing groove 11123 are both arranged around the accommodating groove 11121 to prevent external dust and other foreign objects from entering the accommodating space 17 when the first pressing part 1111 and the second pressing part 1112 are sealed and connected through the sealing part.

[0050] According to another embodiment of the present invention, the multiple air blowing pipes also include a third air blowing pipe 133, which is arranged on the bottom wall of the accommodating groove 11121, and the pipe mouth of the third air blowing pipe 133 is arranged opposite to an effective surface of the workpiece, so that the flow direction of the airflow blown out by the third air blowing pipe 133 is perpendicular to the effective surface, which helps to blow foreign matter away from the effective surface through the third air blowing pipe 133, so that the foreign matter can leave the accommodating space 17 from the air intake port 11124 along with the suction airflow generated by the suction mechanism 12, thereby ensuring the cleanliness of the workpiece surface. It should be noted that the number of third air blowing pipes 133 is at least two, and at least two third air blowing pipes 133 are arranged at intervals along the extension direction of the suction port 11124.

[0051] In addition, in one embodiment, the positioning mechanism 11 further includes a positioning assembly 112, which includes a driving component 1121 and a positioning block 1122 in transmission connection with the driving component 1121. The second pressing member 1112 defines a through hole 11122 for the positioning block 1122 to enter and exit the accommodating space 17, so that the driving component 1121 can drive the positioning block 1122 to abut or separate from the workpiece located in the accommodating space 17. The driving component 1121 drives the positioning block 1122 to abut against the workpiece. Generally, the positioning block 1122 abuts against a non-active surface of the workpiece, thereby positioning the workpiece and preventing large displacement of the workpiece during processing that could affect the workpiece quality. The driving component 1121 may be a pneumatic cylinder, an oil cylinder, or the like.

[0052] According to one embodiment of the present invention, the first pressure-covering part 1111 and the second pressure-covering part 1112 are both flexible pressure-covering parts, the positioning block 1122 is a flexible positioning block 1122, and the first pressure-covering part 1111, the second pressure-covering part 1112 and the positioning block 1122 can all be rubber or silicone parts to prevent the first pressure-covering part 1111, the second pressure-covering part 1112 and the positioning block 1122 from scratching, crushing and bumping the workpiece.

[0053] Furthermore, in one embodiment, the positioning mechanism 11 further includes an elastic positioning member 113, which is connected to the first pressing member 1111. One end of the elastic positioning member 113, which faces the second pressing member 1112, is configured to abut the workpiece. Compared to using a rigid structure to tightly position the workpiece, positioning the workpiece using the elastic positioning member 113 not only ensures reliable positioning of the workpiece, but also effectively prevents the workpiece from being easily crushed or scratched during processing due to tight positioning. It should be noted that the elastic positioning member 113 may be a plunger.

[0054] According to one embodiment of the present invention, there are multiple elastic positioning members 113 , and the multiple elastic positioning members 113 are arranged at intervals along the extension direction of the air intake 11124 , thereby effectively improving the reliability of the elastic positioning members 113 in positioning the workpiece.

[0055] In addition, in one embodiment, the dust-free processing jig 1 further includes a lifting mechanism 16, which is connected to the first pressing part 1111 to drive the first pressing part 1111 to move toward or away from the second pressing part 1112. By setting the lifting mechanism 16 to drive the first pressing part 1111 to move toward or away from the second pressing part 1112, the degree of automation of the dust-free processing jig 1 is effectively improved. The lifting mechanism 16 can be a cylinder or a screw assembly. It should be noted that the lifting stroke of the first pressing part 1111 is adjustable to accommodate workpieces of different thicknesses.

[0056] Moreover, in one embodiment, the dust-free processing jig 1 further includes a mounting frame 14, which is detachably connected to the second pressing member 1112, and the lifting mechanism 16 is detachably connected to the first pressing member 1111. Due to the size differences between different models of workpieces, in order to ensure the processing quality of the workpieces, each model is generally processed by corresponding processing equipment, which results in a low degree of commonality of the processing equipment; the first pressing member 1111 is designed to be detachably connected to the lifting mechanism 16, and the second pressing member 1112 is detachably connected to the mounting frame 14, so that when facing workpieces of different sizes, the first pressing member 1111 and the second pressing member 1112 can be replaced separately to adapt to the size of the workpiece, ensure the processing quality of the product, and improve the reuse rate of other equipment. Among them, other equipment such as Figure 6 shown.

[0057] According to an embodiment of the present invention, the positioning block 1122 is detachably connected to the driving component 1121 , so that the positioning block 1122 adapted thereto can be replaced according to different workpieces, thereby improving the reliability of the positioning block 1122 in positioning the workpiece.

[0058] According to another embodiment of the present invention, the dust-free processing jig 1 also includes an auxiliary positioning mechanism 15, which includes a first auxiliary positioning member 151 and a second auxiliary positioning member 152. The first auxiliary positioning member 151 and the second auxiliary positioning member 152 are both installed in the accommodating groove 11121. The number of the first auxiliary positioning member 151 and the second auxiliary positioning member 152 is multiple, and the first auxiliary positioning member 151 and the second auxiliary positioning member 152 are arranged at intervals. Multiple first auxiliary positioning members 151 are arranged at intervals, and multiple second auxiliary positioning members 152 are also arranged at intervals. The first auxiliary positioning member 151 and the second auxiliary positioning member 152 are both used to assist in positioning the workpiece. Since the first auxiliary positioning member 151 and the second auxiliary positioning member 152 are both detachably connected to the second pressing member 1112, they can be flexibly adjusted according to the different positioning requirements of different workpieces. They can be replaced or their installation positions can be changed to improve adaptability to different workpieces. It should be noted that the first auxiliary positioning member 151 and the second auxiliary positioning member 152 have different shapes to meet the positioning requirements of different positions of the workpiece, wherein the first auxiliary positioning member 151 is a trapezoidal block, and the second auxiliary positioning member 152 is a rectangular block.

[0059] In addition, the present invention also provides a control method for a dust-free processing jig, which is applied to the above-mentioned dust-free processing jig, wherein the dust-free processing jig further includes a lifting mechanism and a blowing mechanism. Figure 7 , Figure 7 1 is a flow chart of a first embodiment of a method for controlling a dust-free processing jig according to the present invention. In one embodiment, the method for controlling a dust-free processing jig includes the following steps:

[0060] S100, placing the workpiece on the second pressing member, and then controlling the lifting mechanism to drive the first pressing member to move toward the second pressing member, so that the first pressing member and the second pressing member are sealed and connected;

[0061] The lifting mechanism is controlled to first drive the first pressing part to move upward so that the workpiece can be placed in the receiving groove of the second pressing part. After the workpiece is placed, the lifting mechanism is controlled to drive the first pressing part to descend, so that the first pressing part and the second pressing part are sealed and connected, that is, the area around the receiving space is sealed, thereby effectively preventing foreign matter such as external dust from entering the receiving space through the connection between the first pressing part and the second pressing part.

[0062] S200, controlling the processing equipment to process the workpiece through the processing port, and controlling the suction mechanism and the blowing mechanism to start at the same time; the blowing mechanism is used to blow foreign matter adsorbed on the surface of the workpiece away from the workpiece, and the suction mechanism is used to absorb the foreign matter and waste generated by the processing equipment during the processing.

[0063] Taking the milling cutter as an example of processing equipment, when the milling cutter is milling the workpiece, part of the debris generated by the processing will be directly sucked in by the suction mechanism through the suction port, and the other part will adhere to the surface of the workpiece located in the circulation space. This part of the debris can be blown away from the surface of the workpiece by the blowing mechanism, and then sucked out from the suction port by the suction mechanism, thereby ensuring the cleanliness of the workpiece surface, so that the surface cleanliness of the workpiece after processing can meet the quality requirements of the product, thereby eliminating the cleaning process and reducing the processing cost of the workpiece.

[0064] The workpiece is placed in the accommodation space, and the first pressure covering member and the second pressure covering member are sealed and connected, so that dust from the outside cannot enter the enclosed space, thereby effectively preventing dust and other foreign matter from adhering to the surface of the workpiece located in the sealed space; the processing equipment processes the workpiece located in the accommodation space through the processing port, and the debris generated during the processing will pass through the circulation space and be sucked into the suction mechanism from the suction port, thereby effectively preventing this part of the debris from being adsorbed on the surface of the workpiece located in the circulation space, and an air blowing mechanism is provided to blow foreign matter adsorbed on the surface of the workpiece away from the surface of the workpiece. This part of the foreign matter separated from the surface of the workpiece will move toward the suction port along with the suction airflow generated by the suction mechanism in the circulation space, and will eventually be sucked into the suction mechanism, so that the cleanliness of the workpiece surface after processing can meet the standard, thereby eliminating the traditional cleaning process and reducing the processing cost of the workpiece. The workpiece can be an optical product, such as an optical lens.

[0065] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields within the concept of the present invention are included in the patent protection scope of the present invention.
