Abstract
Description
Technical Field
[0001] This application relates to the field of polishing and dust collection equipment technology, and in particular to a dust collection port structure for polishing equipment and a light guide plate polishing equipment. Background Technology
[0002] In the manufacturing process of light guide plates, injection molding is typically used to produce a preliminary light guide plate blank. This blank is then sequentially fed to a cutting machine and a polishing platform by a robotic arm for post-processing. In the cutting process, the robotic arm places the light guide plate on the cutting machine platform, where the machine removes the sprue, giving the product its basic shape. In the polishing process, high-speed rotating diamond cutters perform fine polishing on the four edges of the light guide plate to meet dimensional accuracy and optical performance requirements.
[0003] In the aforementioned process, the high-speed rotating diamond tool generates a large amount of dust during polishing. Existing equipment typically only has an overhead dust extraction system to remove this dust. However, in actual processing, it has been found that dust also concentrates on the left and right sides of the product, making it difficult for a single overhead suction system to completely remove all the dust. This results in some dust remaining on the product surface and surrounding areas after polishing. Furthermore, this residual dust may not only affect the product quality in subsequent processes but also have adverse effects on the workshop environment and the health of operators.
[0004] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Utility Model Content

[0034] Please refer to the following: Figures 1 to 5The first embodiment of this application provides a dust suction port structure 10 for a polishing device. The dust suction port structure 10 includes a dust suction lower cover plate 11, a tool holder connecting block 12, a main negative pressure connecting block 13, and an auxiliary negative pressure connecting block 14. The dust suction lower cover plate 11 has a polishing end face 111 and an assembly end face 112 arranged opposite each other along the thickness direction. The polishing end face 111 is the end face of the dust suction lower cover plate 11 facing the workpiece being polished. The assembly end face 112 has an adsorption section 113 and a negative pressure connecting section 114 connected along the length direction. The tool holder connecting block 12 is detachably connected to the adsorption section 113. Both the main negative pressure connecting block 13 and the auxiliary negative pressure connecting block 14 are detachably connected to the negative pressure connecting section 114, and the main negative pressure connecting block 13 is located between the auxiliary negative pressure connecting block 14 and the tool holder connecting block 12. The tool holder... The connecting block 12 and the dust collection cover plate 11 are provided with main dust collection holes 15. It should be noted that the polishing head is also set in the main dust collection hole 15. The main negative pressure connecting block 13 is provided with a main dust collection channel 16 that communicates with the main dust collection hole 15. The main negative pressure connecting block 13 is used to connect to a negative pressure source to provide a negative pressure environment for the main dust collection hole 15 and the main dust collection hole 16. The assembly end face 112 is also provided with an auxiliary dust collection channel 17. The outer periphery of the main dust collection hole 15 is provided with an auxiliary dust collection hole 18 that communicates with the auxiliary dust collection channel 17. The blade holder connecting block 12, the main negative pressure connecting block 13 and the auxiliary negative pressure connecting block 14 cooperate to seal the auxiliary dust collection channel 17. The auxiliary negative pressure connecting block 14 is used to connect to a negative pressure source to provide a negative pressure environment for the auxiliary dust collection channel 17 and the auxiliary dust collection hole 18.
[0035] As can be seen, the suction port structure 10 achieves simultaneous suction from multiple locations above. During operation, the blade is typically positioned within the main suction port 15. By establishing the main suction channel 16 and the main suction port 15, a main suction area is formed above the blade, minimizing the possibility of dust escape and splashing. By setting the auxiliary suction port 18 and the auxiliary suction channel 17, with the auxiliary suction port 18 positioned on the outer periphery of the main suction port 15, a second suction area is constructed around the main suction area. This effectively performs secondary suction of dust escaping from the main suction port 15, enhancing the suction effect and reducing dust residue. The suction port structure 10 thus creates a multi-directional and efficient suction effect above, significantly improving dust removal during the polishing process and enhancing product quality and the workshop environment. It should be noted that the channel formed by the main suction port 15 and the main suction channel 16 is mutually isolated and sealed from the channel formed by the auxiliary suction port 18 and the auxiliary suction channel 17.
[0036] In some preferred embodiments, the opening of the main suction hole 15 is recessed relative to the opening of the auxiliary suction hole 18. That is, the distance between the opening of the main suction hole and the assembly end face 112 is less than the distance between the auxiliary suction hole 18 and the assembly end face 112; thus, the auxiliary suction hole 18 surrounds the outer periphery of the main suction hole 15, effectively blocking and adsorbing polishing debris escaping from the main suction hole 15, thereby improving suction efficiency and product quality.
[0037] In some preferred embodiments, the auxiliary suction hole 18 has an angle range of not less than 270° around the outer periphery of the main suction hole 15. That is, the circumferential angle covered by the auxiliary suction hole 18 around the outer periphery of the main suction hole 15 is not less than 270°. This means that a second negative pressure suction area can be formed in the front, left, and right directions of the main suction hole 15, thereby preventing polishing debris from splashing onto the workpiece to be polished.
[0038] In some preferred embodiments, the auxiliary suction holes 18 include a first auxiliary suction hole 181, a second auxiliary suction hole 182, and a third auxiliary suction hole 183. The first auxiliary suction hole 181 is located on the side of the main suction hole 15 away from the negative pressure connecting section 114. The second auxiliary suction hole 182 and the third auxiliary suction hole 183 are both located on both sides of the first auxiliary suction hole 181. The angle range of the first auxiliary suction hole 181, the second auxiliary suction hole 182, and the third auxiliary suction hole 183 on the outer periphery of the main suction hole 15 is no greater than 90°. Specifically, the first auxiliary suction hole 181, the second auxiliary suction hole 182, and the third auxiliary suction hole 183 each cover a 90° area to prevent polishing debris from splashing onto the workpiece to be polished.
[0039] In some preferred embodiments, the polishing end face 111 is provided with a first baffle 191, a second baffle 192, and a third baffle 193 located on the outer periphery of the main suction hole 15. The first auxiliary suction hole 181 is formed on the first baffle 191, the second auxiliary suction hole 182 is formed on the second baffle 192, and the third auxiliary suction hole 183 is formed on the third baffle 193. By setting the first baffle 191, the second baffle 192, and the third baffle 193, the openings of the first auxiliary suction hole 181, the second auxiliary suction hole 182, and the third auxiliary suction hole 183 are all convex outward relative to the main suction hole 15, preventing polishing debris from escaping. At the same time, by setting the first baffle 191, the second baffle 192, and the third baffle 193, they can also serve as physical barriers, further preventing polishing debris from escaping and ensuring the debris adsorption effect.
[0040] In some preferred embodiments, the first baffle 191, the second baffle 192, and the third baffle 193 are all configured as arc-shaped baffle structures, and the first auxiliary suction hole 181, the second auxiliary suction hole 182, and the third auxiliary suction hole 183 are all configured as arc-shaped elongated holes. The first baffle 191, the second baffle 192, and the third baffle 193 all have inner walls and outer walls, and the height of the inner walls is lower than the height of the outer walls. This not only facilitates the intake of debris and dust, but also allows the outer walls to block debris and dust, further improving the suction effect of the suction port structure 10.
[0041] In some preferred embodiments, the auxiliary suction channel 17 includes a circular channel 171, a first straight channel 172, and a second straight channel 173. The arc angle of the circular channel 171 is not less than 270°. The circular channel 171 is arranged around the outer periphery of the main suction hole 15. The first straight channel 172 and the second straight channel 173 are symmetrically arranged at both ends of the circular channel 171. This ensures that the middle area of the circular channel 171 has a sufficiently strong negative pressure environment, while also preventing the circular channel 171 from experiencing [unspecified issues]. Blockage; it should be noted that the auxiliary suction holes 18 are located in the area of the circular channel 171 and are evenly spaced; the blade holder connecting block 12 cooperates with the suction lower cover plate 11 to seal the circular channel 171, the main negative pressure connecting block 13 and the auxiliary negative pressure connecting block 14 cooperate with the suction lower cover plate 11 to seal the first straight channel 172 and the second straight channel 173, and the auxiliary suction holes 18 are connected to the negative pressure source through the circular channel 171, the first straight channel 172, the second straight channel 173 and the auxiliary negative pressure connecting block 14.
[0042] In some preferred embodiments, the first straight channel 172 and the second straight channel 173 both have a first cross section, and the circular channel 171 has a second cross section. The area of the second cross section is smaller than the area of the first cross section, thereby ensuring that the circular channel 171 has a sufficiently strong negative pressure environment and ensuring the negative pressure suction effect of the auxiliary suction hole 18.
[0043] In some preferred embodiments, a sealing structure 194 is also provided on the assembly end face 112. The sealing structure 194 is arranged around the outside of the auxiliary dust suction channel 17 and the auxiliary dust suction hole 18, thereby avoiding pressure leakage defects between the dust suction lower cover plate 11, the knife holder connecting block 12, the main negative pressure connecting block 13 and the auxiliary negative pressure connecting block 14, and ensuring the dust suction effect of the dust suction port structure 10.
[0044] In some preferred embodiments, a dust suction hood 195 is also connected to the outside of the main dust suction hole 15. By setting the dust suction hood 195, the negative pressure adsorption capacity at the main dust suction hole 15 can be further increased, ensuring the dust suction effect of the dust suction port structure 10.
[0045] The second embodiment of this application also provides a light guide plate polishing device, which includes the dust suction port structure 10 as described in the first embodiment of this application. This effectively avoids the defect of incomplete dust and debris adsorption when using upper dust suction during light guide plate polishing; see the first embodiment of this application for details.
[0046] In summary, this application provides a dust suction port structure for a polishing equipment and a light guide plate polishing equipment. The dust suction port structure includes a dust suction lower cover plate, a tool holder connecting block, a main negative pressure connecting block, and an auxiliary negative pressure connecting block. The dust suction lower cover plate has a polishing end face and an assembly end face arranged opposite each other along the thickness direction. The assembly end face has an adsorption section and a negative pressure connecting section connected along the length direction. The tool holder connecting block is detachably connected to the adsorption section. Both the main negative pressure connecting block and the auxiliary negative pressure connecting block are detachably connected to the negative pressure connecting section, and the main negative pressure connecting block is located between the auxiliary negative pressure connecting block and the tool holder connecting block. The blade holder connecting block and the dust collection lower cover plate are provided with a main dust collection hole. The main negative pressure connecting block is provided with a main dust collection channel communicating with the main dust collection hole. The main negative pressure connecting block is used to connect to a negative pressure source to provide a negative pressure environment for the main dust collection hole and the main dust collection hole. An auxiliary dust collection channel is also provided on the assembly end face. An auxiliary dust collection hole communicating with the auxiliary dust collection channel is provided on the outer periphery of the main dust collection hole. The blade holder connecting block, the main negative pressure connecting block and the auxiliary negative pressure connecting block cooperate to seal the auxiliary dust collection channel. The auxiliary negative pressure connecting block is used to connect to a negative pressure source to provide a negative pressure environment for the auxiliary dust collection channel and the auxiliary dust collection hole. The suction port structure enables simultaneous suction from multiple locations above. During operation, the blade head is typically positioned within the main suction port. By establishing the main suction channel and main suction port, a main suction area is formed above the blade head, minimizing the possibility of dust escape and splashing. By setting up auxiliary suction ports and auxiliary suction channels, and placing the auxiliary suction ports on the outer periphery of the main suction port, a second suction area is created around the main suction area. This effectively performs secondary suction of dust escaping from the main suction port, enhancing the suction effect and reducing dust residue. This results in a multi-directional and highly efficient suction effect above, significantly improving dust removal during the polishing process and enhancing product quality and the workshop environment.
[0047] It should be understood that the application of this application is not limited to the examples above.
