Description

Technical Field

[0001] The utility model relates to the technical field of velvet making and cleaning machines, in particular to an angle-adjustable loading and unloading structure of a velvet making and cleaning machine. Background Art

[0002] In silicon wafer processing, texturing and cleaning are often performed together. First, texturing forms the textured surface, followed by cleaning to remove contaminants and impurities generated during the texturing process. This ensures the wafer surface maintains both a textured surface and cleanliness, providing a high-quality surface for subsequent processes. Texturing cleaning machines are crucial equipment in the wafer texturing and cleaning process.

[0003] The silicon wafer texturing and cleaning machine is a device that combines texturing and cleaning functions. It can form tiny protruding structures (i.e., texturing surfaces) on the surface of silicon wafers while removing pollutants and impurities from the surface of the silicon wafers. During the use of the silicon wafer texturing and cleaning machine, after texturing is completed, the silicon wafers need to be cleaned to remove chemical solution residues, particulate matter, and other pollutants on the surface. During the cleaning process, the staff is required to load the silicon wafers into a basket and place the basket into the cleaning tank of the equipment. Currently, the loading and unloading of the basket mostly relies on manual operation by the staff. Since the cleaning fluid is corrosive, the staff are easily injured during the process of taking and placing the basket. At the same time, the manual loading and unloading method also has the disadvantage of inconvenient operation. In view of this, we propose an angle-adjustable loading and unloading structure for the texturing and cleaning machine. Utility Model Content

Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0027] This embodiment provides a technical solution:

[0028] See also Figures 1-4As shown, the angle-adjustable loading and unloading structure of the velveting cleaning machine includes a base 1, a bracket 11 is fixed on the top of the base 1; an adjusting part 2 is provided above the base 1, the adjusting part 2 includes a rotating shaft 23 that passes through the bracket 11 and is rotatably connected to the bracket 11, the external coaxial key of the rotating shaft 23 is connected to a first gear 24, and a second gear 25 is engaged with one side of the first gear 24; a second motor 26 for driving the second gear 25 to rotate is installed on the top of the bracket 11; a support 20 is coaxially fixed to the top of the rotating shaft 23, and an installation groove 200 is opened on the outer wall of the support 20, a threaded rod 21 is rotatably installed in the installation groove 200, and a threaded rod 21 for driving the threaded rod 2 is installed on the top of the support 20. The first motor 22 rotates as shown in FIG1 . A lifting plate 27 is threadedly connected to the threaded rod 21. A fixing groove 270 is defined at the front end of the lifting plate 27. A strip groove 271 is defined at the rear side of the fixing groove 270. A sliding hole 272 is defined at the rear end of the strip groove 271. A slider 28 is slidably mounted in the strip groove 271. A sliding rod 280 slidably connected to the sliding hole 272 is fixed to the rear end of the slider 28. A spring 281 is sleeved on the outside of the sliding rod 280 for pressing against the slider 28. A limiting rod 282 is coaxially fixed to the front end of the slider 28. A limiting hole 330 is defined at the upper rear end surface of the connecting rod 33. The limiting rod 282 is plugged into and engaged with the corresponding limiting hole 330. A clamping part 3 for clamping a flower basket is installed at the lower front end of the lifting plate 27. The clamping part 3 includes a connecting rod 33 detachably connected to the fixing groove 270. A fixing seat 30 is fixed to the bottom of the connecting rod 33. A groove 300 is provided at the bottom of the fixing seat 30. A double-headed screw rod 31 is rotatably installed in the groove 300; a third motor 32 for driving the double-headed screw rod 31 to rotate is installed at the end of the fixing seat 30; a splint 34 is threadedly connected to the threads at both ends of the double-headed screw rod 31, and a horizontal support plate 35 for lifting the flower basket is fixed to one side wall of the splint 34 near the bottom end.

[0029] In this embodiment, a push block is fixed on the top of the slider 28, and the cross-sectional shape of the push block is trapezoidal. By setting the trapezoidal push block, it is convenient to push the slider 28 to move, meeting the needs of disassembling the connecting rod 33 and the clamping part 3.

[0030] In this embodiment, mounting holes 10 are provided at the four corners of the top of the base 1. The overall shape of the mounting holes 10 is circular. The arrangement of the mounting holes 10 facilitates the insertion of bolts, thereby facilitating the mounting of the base 1 on a cleaning machine or other fixed platform by bolts.

[0031] In this embodiment, the overall shape of the bracket 11 is U-shaped, and the bracket 11 is fixedly connected to the base 1 by bolts. The U-shaped bracket 11 provides a stable support for the rotating shaft 23 and the support 20, and the bolt fixing method ensures the installation reliability of the bracket 11.

[0032] In this embodiment, two triangular reinforcement blocks 350 are welded tightly to the connection between the clamping plate 34 and the supporting plate 35. The reinforcement blocks 350 enhance the stability of the connection between the clamping plate 34 and the supporting plate 35, thereby increasing the clamping and lifting effect on the flower basket.

[0033] In this embodiment, the slider 28 and the limiting rod 282 are integrally formed, and both are made of stainless steel. This integrally formed structure provides enhanced connection strength, ensuring a secure and stable connection between the slider 28 and the limiting rod 282 while also ensuring that the limiting rod 282 retains the limiting hole 330. Stainless steel is corrosion-resistant and strong, ensuring the longevity of the slider 28 and the limiting rod 282.

[0034] It can be understood that the two side walls of the installation groove 200 in this embodiment are fixed with guide rails 201, and the rear ends of the two side walls of the lifting plate 27 are provided with guide grooves that are slidably connected to the guide rails 201. The setting of the guide rails 201 and the guide grooves increases the stability and smoothness of the lifting plate 27 during the lifting and lowering movement.

[0035] It should be added that the thread winding directions at both ends of the double-ended screw 31 in this embodiment are opposite. When the double-ended screw 31 rotates, the clamping plates 34 on both sides can move synchronously relative to each other, and the clamping plates 34 can synchronously drive the supporting plates 35 on both sides to move synchronously relative to each other. This design is conducive to the clamping of the flower basket by the clamping plates 34 on both sides, which is conducive to the loading and unloading processing of the flower basket.

[0036] It is worth noting that the first motor 22 , the second motor 26 and the third motor 32 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0037] During specific use, the user first places the flower basket between the two clamping plates 34, then the user turns on the power of the third motor 32, the third motor 32 starts to work, the output shaft of the third motor 32 rotates to drive the double-headed screw 31 to rotate, as the double-headed screw 31 rotates, the clamping plates 34 on both sides move synchronously relative to each other, and the clamping plates 34 move closer to the flower basket. When the clamping plates 34 clamp the two side walls of the flower basket, the user stops the power of the third motor 32, and then the user turns on the power of the second motor 26, the second motor 26 starts to work, the output shaft of the second motor 26 rotates to drive the second gear 25 to rotate, and the second gear 25 rotates with the first gear. The wheels 24 are engaged, the first gear 24 rotates and drives the rotating shaft 23 and the support 20 to rotate, and the support 20 drives the lifting plate 27 and the clamping part 3 to rotate. When the clamping part 3 moves to the top of the cleaning tank, the user stops the power supply of the second motor 26, and then the user turns on the power supply of the first motor 22. The first motor 22 starts to work, and the output shaft of the first motor 22 rotates to drive the threaded rod 21 to rotate. As the threaded rod 21 rotates, the lifting plate 27 moves downward and drives the flower basket downward. When the flower basket enters the cleaning tank, the user stops the power supply of the first motor 22. At this time, the silicon wafers in the flower basket can be cleaned.
