Description

Technical Field

[0001] The utility model relates to the field of chemical polishing, in particular to a chemical polishing and swinging device. Background Art

[0002] The chemical polishing process is a production method commonly used to obtain a high-quality surface effect, and is generally applied to the surface processing of special materials in the semiconductor and 3C industries. Taking glass chemical polishing as an example, referring to Figure 1 , the existing chemical polishing machine (also called liquid polishing machine) includes a chemical polishing tank 1' and a rack 2' arranged in the chemical polishing tank 1'. The chemical polishing tank 1' is used to hold the chemical solution. The rack 2' is vertically arranged, the upper and lower sides of the rack 2' are long sides, and the left and right sides are short sides. The rack 2' is used to limit the front and back positions of a row of glasses arranged in the front and back directions. The glasses are vertically placed and perpendicular to the arrangement direction of the glasses. Baffle rods are respectively arranged on both sides of the left and right short sides of the rack 2' to limit the left and right sides of the glasses. A water droplet rod is arranged below the bottom long side of the rack 2' to support the glasses. The extending directions of the water droplet rod and the baffle rods are both parallel to the arrangement direction of the glasses. A row of beads is sleeved on the baffle rods, and the glasses are placed on the water droplet rod. One glass is clamped between adjacent beads. After the glass is placed on the rack 2', the chemical polishing operation is carried out in a static state.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0044] Reference Figure 2 , the chemical polishing and swinging device of this embodiment can be applied to the chemical polishing tank 1 of a chemical polishing machine and can be used for product chemical polishing. The product of this embodiment is specifically glass. It can be understood that the product is not limited to glass and can also be any other product that requires chemical polishing, such as semiconductor and surface processing of special materials in the 3C industry.

[0045] Reference Figure 3 , the chemical polishing and swinging device of this embodiment mainly includes a power and deceleration unit 2, a rotating and lifting unit 3, a bracket unit 4, a bottom plate unit 5, and a rack unit 6.

[0047] Considering that some potions are highly corrosive, in this embodiment, the materials that will come into contact with the potion and the materials that may be exposed to the surrounding of the potion for a long time are all made of materials resistant to strong acids and alkalis. For example, materials with higher rigidity requirements are all made of stainless steel 904L, and materials with relatively lower rigidity requirements can be made of PEEK, effectively avoiding strong acid and alkali corrosion.

[0048] Theoretically, the number of the bracket units 4 can be one or N, where N is greater than 1. Refer to Figure 2-4 , in this embodiment, the number of the bracket units 4 is 2. The number of the rack units 6 is the same as that of the bracket units 4, which is also N. The N bracket units 4 are arranged in the front and rear directions, and the N rack units 6 are also arranged in the front and rear directions.

[0049] The following is a detailed description of each structure.

[0050] Refer to Figure 5-6 , combined with Figure 2-3 , the chemical polishing tank 1 is a rectangular tank formed by enclosing with sheet metal, and includes four side walls in the front, rear, left, and right directions. The power and speed reduction unit 2 is installed on the left side wall of the chemical polishing tank 1 and is located at a position close to the rear side wall. Of course, it can also be changed to be installed at a position close to the front side wall of the left side wall, or it can be changed to the front / rear side wall position of the right side wall.

[0051] The power and speed reduction unit 2 includes a first synchronous pulley 21 driven by the synchronous belt 37 with the rotating lifting unit 3, two sensors 22, a motor and reducer assembly 23, a mounting seat 24, and a protective cover 25.

[0052] The motor and reducer assembly 23 is composed of a motor and a reducer, aiming to output a lower rotational speed, and is generally L-shaped as a whole. The mounting seat 24 is mounted on the inner side of the left side wall of the chemical polishing tank 1 by screws or the like. The mounting seat 24 is in the shape of a box body open on the left side and the top. The motor and reducer assembly 23 is located outside the left side wall of the chemical polishing tank 1, passes through the left side wall of the chemical polishing tank 1 and is locked with the mounting seat 24. The rotating shaft of the motor and reducer assembly 23 extends in the left-right direction, passes through the right side wall of the mounting seat 24 and is sleeved with the first synchronous pulley 21 on the outside. The protective cover 25 is locked with the outside of the left side wall of the chemical polishing tank 1 by screws, and covers the motor and reducer assembly 23 and the open opening at the top of the mounting seat 24. Refer to Figure 5-6 and Figure 9 , two of the sensors 22 are installed side by side left and right on the rear side wall of the mounting seat 24 and face the circumferential surface of the rotating shaft 31.

[0053] Refer to Figure 3-4 and Figure 7-9 , the rotating and lifting unit 3 includes a reel lifting mechanism, two rows of left and right steering wheels 34, and two groups of left and right suspension ropes 35 corresponding to the two rows of steering wheels 34. The reel lifting mechanism includes a second synchronous pulley 36, a synchronous belt 37, a rotating shaft 31, two left and right shaft mounting seats 32, two left and right suspension rope clamping blocks 33 corresponding to the two groups of left and right suspension ropes 35, and two induction sheets 38. In this embodiment, the suspension rope 35 is a 904 stainless steel wire rope, and the synchronous belt 37 is a PU polyurethane synchronous belt.

[0054] Because the power and speed reduction unit 2 is located against the rear side wall of the chemical polishing tank 1, the overall reel lifting mechanism is arranged on the rear side wall of the chemical polishing tank 1. The two shaft mounting seats 32 are separately mounted on the rear side wall of the chemical polishing tank 1 by screws in the left and right directions. The axial direction of the rotating shaft 31 is along the left and right direction, and its left and right ends are respectively rotatably mounted on the left and right shaft mounting seats 32. The two sling clamping blocks 33 are coaxially and fixedly mounted at the left and right ends of the rotating shaft 31. The sling clamping block 33 is a cylindrical structure with a plurality of annular grooves opened on its circumferential surface. The plurality of annular grooves are arranged side by side along the axial direction of the sling clamping block 33. Two rows of turning wheels 34 are respectively arranged on the left and right side walls of the chemical polishing tank 1 along the front and rear directions. The first ends of the two groups of sling ropes 35 are respectively fixedly mounted on the two sling clamping blocks 33. Each annular groove of the sling clamping block 33 engages a sling rope 35, for example, the sling rope 35 is wound around the annular groove and then tied tightly. Each group of sling ropes 35 extends horizontally in the front and rear direction from the corresponding sling clamping block 33 to the corresponding row of turning wheels 34 and then turns downward around the turning wheels 34. The second ends of each group of sling ropes 35 are connected to the bracket unit 4. Because the power and speed reduction unit 2 is arranged on the left side wall of the chemical polishing tank 1, a second synchronous pulley 36 is coaxially and fixedly mounted at the left end of the rotating shaft 31. The synchronous belt 37 is sleeved on the first synchronous pulley 21 and the second synchronous pulley 36 to realize the rotational transmission between the power and speed reduction unit 2 and the rotational lifting unit 3. In this embodiment, the first synchronous pulley 21 is specifically a 24-tooth synchronous pulley, and the second synchronous pulley 36 is specifically a 48-tooth synchronous pulley.

[0055] Reference Figure 9 , the two sensing pieces 38 and the second synchronous pulley 36 are fixedly mounted at the same end of the rotating shaft 31, and both are mounted at the left end of the rotating shaft 31. The two sensing pieces 38 are separated in the left and right direction and are arranged at a staggered angle. For example, in this embodiment, the two sensing pieces 38 are both semi-circular pieces, and the two semi-circular pieces are staggered by 180°. The two sensors 22 are arranged side by side in the left and right direction. The two sensors 22 correspond to the two sensing pieces 38. The sensor 22 is specifically an optocoupler. During the rotation of each sensing piece 38, it will pass between the emitter and the receiver of the corresponding optocoupler. The sensor 22 is used to assist in setting the forward and reverse rotation extreme limits of the rotating shaft 31 by sensing the corresponding sensing piece 38.

[0056] Specifically, one sensor 22 and the sensing piece 38 sense the forward rotation extreme limit. If the corresponding sensing piece 38 cannot be sensed, it is considered that the forward rotation extreme limit has been reached, and the forward rotation is stopped and changed to reverse rotation. In this way, the product will no longer be lifted but will be lowered instead; on the contrary, the other sensor 22 and the sensing piece 38 sense the reverse rotation extreme limit. If the corresponding sensing piece 38 cannot be sensed, it is considered that the reverse rotation extreme limit has been reached, and the reverse rotation is stopped and changed to forward rotation. In this way, the product will no longer be lowered but will be lifted instead.

[0057] Reference Figure 4 , each row of the steering wheels 34 is divided into N groups corresponding to the N bracket units 4. In this embodiment, N is 2. Of course, N can also be other numbers. Each group of steering wheels 34 includes M steering wheels 34. In this embodiment, M is 2. Of course, M can also be greater than 2. Each of the steering wheels 34 corresponds to a suspension rope 35. The first end of each suspension rope 35 is fixed to the corresponding suspension rope clamping block 33. After each suspension rope 35 turns around the corresponding steering wheel 34 and faces downward, its second end is connected to the corresponding bracket unit 4.

[0058] Reference Figure 10-11 , the steering wheel 34 includes a clamping block 342, a bearing 343 made of 6800peek material, a steering wheel body 341, and a steering wheel shaft 344. The clamping block 342 is clamped on the left / right side wall of the chemical polishing tank 1 and locked by screws. The steering wheel body 341 is sleeved outside the bearing 343 to achieve rotation. The steering wheel shaft 344 passes through the centers of the steering wheel body 341 and the bearing 343 in the left-right direction and is locked to the clamping block 342.

[0059] Reference Figure 12 , the bracket unit 4 includes a group of first bracket rods 41 arranged side by side front and back with a gap, two groups of second bracket rods 42 separated left and right, and a group of water droplet rods 43 arranged side by side left and right with a gap. The first bracket rods 41 extend in the left-right direction, the second bracket rods 42 extend in the vertical direction, and the water droplet rods 43 extend in the front-back direction. The bottom ends of the two groups of second bracket rods 42 are respectively connected to the left and right ends of a group of the first bracket rods 41. The top ends of the two groups of second bracket rods 42 are respectively connected to the suspension ropes 35 on a group of the steering wheels 34 on the left and right sides. The water droplet rods 43 are arranged on a group of the first bracket rods 41.

[0060] In this embodiment, the number of the first bracket rods 41 in a group of the first bracket rods 41 is the same as the number of the steering wheels 34 in a group of the steering wheels 34, which is also M. The number of the second bracket rods 42 in each group of the second bracket rods 42 is also M, and M is greater than 1. The number of the water droplet rods 43 in a group of the water droplet rods 43 is K, and K is greater than 1.

[0061] Theoretically, the water droplet rods 43 can be directly installed on the first bracket rods 41. In this embodiment, they are indirectly installed on the first bracket rods 41. Specifically, each of the bracket units 4 further includes M groups of third bracket rods 44 extending in the vertical direction corresponding to the M groups of the first bracket rods 41. Each of the first bracket rods 41 is connected to a group of the water droplet rods 43 through a corresponding group of the third bracket rods 44. The number of the third bracket rods 44 in each group of the third bracket rods 44 is the same as the number of the water droplet rods 43 in a group of the water droplet rods 43, both of which are K.

[0062] ReferenceFigure 13-14 The bottom plate unit 5 includes a rectangular bottom plate 50 and guide rods 51 vertically installed on the bottom plate 50. The rectangular bottom plate 50 is placed at the bottom of the chemical polishing tank 1. The third bracket rod 44 is vertically and movably inserted into the guide rod 51, so as to play a guiding role and ensure that the bracket unit 4 is smoothly lifted in the chemical polishing tank 1 without displacement.

[0063] Continue to refer to Figure 3 Each rack unit 6 includes two vertically arranged rack plates 61 arranged at intervals in the front and rear, and at least one set of stop bars 62 connected between the two rack plates 61. In this embodiment, there are two sets of stop bars 62, and the two sets of stop bars 62 are distributed directly above and below each other. Each set of the stop bars 62 is respectively close to the left and right sides of the rack plate 61 to limit the left and right sides of the product. The stop bars 62 extend in the front-rear direction and are strung with a row of beads 63, and adjacent beads 63 are used to clamp a product.

[0064] Correspondingly, in order to position and place the rack unit 6, refer to Figure 13-14 The bottom plate unit 5 includes a bottom plate 50 and rack support strips 52 corresponding to the respective rack plates 61. The rack support strips 52 are fixed on the bottom plate 50 and are used to position and insert the rack plates 61. For example, in this embodiment, the rack support strips 52 have left and right clamping blocks 522 arranged at intervals in the left-right direction for left and right limiting of the rack plates 61, and two pairs of clamping blocks 521 located between the left and right clamping blocks 522 for front and rear limiting of the rack plates 61. The two pairs of clamping blocks 521 are distributed at intervals left and right. Each pair of clamping blocks 521 is arranged directly opposite in the front-rear direction. Combining Figure 3 The left and right sides of the rack plate 61 are inserted into the left and right clamping blocks 522, and the bottom side of the rack plate 61 is inserted between each pair of clamping blocks 521.

[0065] In order to improve the stability of the rack unit 6, the rack unit 6 further includes a reinforcing plate 64. The reinforcing plate 64 is vertically arranged and located in the middle of the two rack plates 61, and the stop bars 62 pass through the reinforcing plate 64. Of course, the reinforcing plate 64 is provided with an avoidance opening for avoiding the water droplet rod 43 in the bracket unit 4, and this avoidance opening allows the water droplet rod 43 to move up and down.

[0066] The device of this embodiment can be used in the chemical polishing tanks of various products. The product is placed on the bracket unit, and the power and reduction unit provides a power source for slow rotation, driving the rotating lifting unit to perform repeated slow lifting and lowering. The rotating lifting unit then drives the bracket unit and the product to move slowly up and down, causing the product to change from a static state to repeated slow up-and-down tossing during the chemical polishing process, achieving the effect of the rack remaining stationary while the product tosses in the liquid polishing tank. The tossing stroke can be set to 0 - 20 mm, avoiding rack marks caused by long-term static state, improving production efficiency, and increasing the production yield of the product from 66% in the static state to about 98.9%. Moreover, the design effect of the entire tossing device closely adheres to the actual production effect, perfectly coordinates with the actions of the original machine, is quick to install, and convenient to debug. This embodiment has a small external volume, saves space, is very suitable for use in a complex environment such as chemical polishing process equipment, is flexible and convenient, and has a wider scope of application. The materials that are easily in contact with the chemical solution are selected as stainless steel 904L or PEEK material, effectively avoiding strong acid and alkali corrosion.
