Description

Retractable guard with wear-resistant protective curtain

The present invention relates to a telescopic shield, in particular to a telescopic shield with a wear-resistant protective curtain.

As shown in Figures 1 and 2, a conventional scale-type telescopic shield for a processing machine (such as a wafer cutting machine, not shown) includes an expandable or retractable protective curtain 1 and a support module. 2, and a scale module 3.

As shown in FIGS. 3, 4 and 5, the protective curtain 1 includes a top curtain body 4 and two side curtain bodies 5 connected to both sides of the top curtain body 4. The top curtain body 4 has a number of ridges 401 arranged in a length direction X and extending along a transverse direction Y, and a number of top folding parts 402 connected between the ridges 401. Each top folding part 402 has two top folding blocks 403 extending downward from any two adjacent ridges 401 and connected to each other, and a first fold 404 formed between the top folding blocks 403 and extending along the transverse direction Y. When the protective curtain 1 is unfolded, each top folding part 402 can define a concave space 405.

Each side panel 5 has a plurality of side ridges 501 and a plurality of side folds 502. Each side fold 502 has two side fold blocks 503 extending inwardly from any two adjacent side ridges 501 and connected to each other, two top fold blocks 403 connected to the side fold blocks 503 and the respective top folds 402. 3 and interconnected with each other, and a second fold 505 formed between the folding anchor blocks 504 and extending along the transverse direction Y, the folding anchor blocks 504 are directly attached to the top pleating blocks 403, and the second fold overlaps the first fold 404.

As shown in Figures 2, 6, and 7, the support module 2 includes a movable plate 201 disposed at the front end of the protective curtain 1, a fixed plate 202 disposed at the rear end of the protective curtain 1, and several fixed plates 202 at the rear end of the protective curtain 1. The peak ridge portion 401 corresponding to the top curtain body 4 and the supporting ribs 203 of the side ridge portions 501 corresponding to the side curtain bodies 5 . The scale module 3 includes several scales 301 with the same specifications, and the scales 301 are connected to the movable plate 201 and the corresponding peak ridge portion 401 .

Thus, as shown in FIGS. 6 and 7 , when the processing machine is to perform processing, the movable plate 201 can be driven forward to unfold the originally folded protective curtain 1, so that the originally overlapped scales 301 are pulled apart to overlap each other front and back, and the top curtain body 4 of the protective curtain 1 is covered. At this time, the supporting ribs 203 are spaced apart from each other to support the unfolded protective curtain 1. In this way, the mechanism (such as a lead screw, not shown) covered by the protective curtain 1 can be protected, and the scales 301 can also protect the top curtain body 4 of the protective curtain 1.

However, since the folding joints 504 of the side folding portions 502 of the side screen bodies 5 are directly attached to the top folding blocks 403 of the top folding portions 402 of the top screen body 4, the first folds 404 of the top folding portions 402 and the second folds 505 of the side folding portions 502 of the side screen bodies 5 are overlapped up and down, so that during the process of unfolding and folding the protective curtain 1, The first folds 404 of the top folds 402 and the second folds 505 of the side folds 502 will always rub against each other, causing the top folds 402 and the side folds 502 to easily break at these locations, resulting in the cutting fluid (such as pure water) used during processing to leak into the interior of the protective curtain 1, causing the mechanism under the protective curtain 1 to rust.

It is therefore an object of the present invention to provide a telescopic shield with a wear-resistant protective curtain that overcomes at least one of the disadvantages of the prior art.

Therefore, the new retractable shield with wear-resistant protective curtain includes a protective curtain unit and a support unit.

The protective curtain unit can change between an unfolded state and a folded state along a length direction, and includes a top curtain body and two side curtain bodies connected to the top curtain body. The top curtain body has several There are peak ridges arranged in the length direction and extending along a transverse direction, and several top folding portions extending along the transverse direction.

Each side curtain body has a number of side ridges arranged in the length direction and corresponding to the peak ridges. , and the number corresponds to the side folding parts of the top folding parts, each side folding part is connected between any two adjacent side ridge parts, and each side folding part has two adjacent side ridge parts from the any two Side folding blocks extending inwardly and connected to each other, two folding connecting blocks connected between the side folding blocks and the top folding blocks of the respective top folding portions and connected to each other, and a folding connection block formed on the side folding blocks. A second crease between the folding connecting blocks, the folding connecting blocks are located under the top folding blocks, the second folding line extends downwardly and inwardly from one end of the first folding line, To gradually separate from the first fold, when the protective curtain unit is in the unfolded state, the peak ridges are separated from each other, the top folds are unfolded, and each top fold defines an inner concave space. The side ridges are separated from each other, and the side folding portions are unfolded. When the protective curtain unit is in the folded state, the peak ridges are close to each other, the top folding portions are folded, and the side ridges are close to each other. The folding part is folded.

The supporting unit includes a plurality of supporting ribs, each of which is connected to a corresponding peak ridge, and opposite ends of each supporting rib are connected to the corresponding side ridges of the side curtain bodies.

The effect of the present invention is that: the second fold of the side fold of the side screen body extends downward and inwardly from one end of the first fold of the top fold of the top screen body, the second fold of the side fold is separated from the first fold of the top fold, and the folding joint of the side fold will not be directly attached to the top fold of the top fold. In the process of unfolding and folding the protective curtain unit, the first folds of the top folds will not rub against the second folds of the side folds, which can effectively prevent the top folds and the side folds from breaking at these locations, preventing the cutting fluid (such as pure water) used during processing from leaking into the interior of the protective curtain unit, so that the mechanism under the protective curtain unit will not rust.

It is understandable that However, in other variations of this embodiment, the number of the recessed spaces 115 of the top folding portion 112 (112I) directly covered by the elongated scales 31 can also be two, three or more than four.

The standard scales 32 are connected to the corresponding ridges 111 (annotated as 111Ⅰ for clear marking) located on both sides of the remaining top folded portion 112 (112Ⅱ), and the standard scales 32 are fixed to the corresponding supporting ribs 22 (annotated as 22Ⅰ for clear marking), and the corresponding supporting ribs 22 (22Ⅰ) are connected to the corresponding ridges 111 (111Ⅰ).

As shown in FIGS. 14 and 15 , when the protective curtain unit 10 is in the unfolded state, the first mounting block 311 of the extended scale 31 is far away from the second mounting block 321 of one of the standard scales 32 that is closest to the extended scale 31, and the first overlapping portion 315 of the first shielding block 312 of the extended scale 31 overlaps the second horizontal plate portion 323 of the second shielding block 322 of one of the standard scales 32. The second mounting blocks 321 of the standard scales 32 are spaced apart from each other, and the rear ends of the second overlapping portions 324 of the second shielding blocks 322 of any two adjacent standard scales 32 are spaced apart from each other. The second shielding blocks 322 of the standard scales 32 overlap each other. Specifically, the second overlapping portion 324 of the second shielding block 322 of the previous standard scale 32 overlaps the second horizontal plate portion 323 of the second shielding block 322 of the next standard scale 32.

As shown in Figures 16 and 17, when the protective curtain unit 10 is in the folded state, the first mounting block 311 of the extended scale 31 is adjacent to the second mounting block 321 of one of the standard scales 32. The extended scale The first shielding block 312 of 31 is located above the second shielding block 322 of the standard scales 32. The second mounting blocks 321 of any two adjacent standard scales 32 are adjacent to each other. The second mounting blocks 321 of any two adjacent standard scales 32 are adjacent to each other. The rear ends of the second overlapping portions 324 of the shielding blocks 322 are adjacent to each other, and the second shielding blocks 322 of the standard scales 32 overlap each other.

Thereby, as shown in Figures 14 and 15, when the processing machine is to perform processing operations, the movable plate 21 can be driven forward to move the protective curtain unit 10 from the folded state (see Figures 16 and 17 ) is unfolded into the unfolded state, so that the originally overlapping extended scales 31 and the standard scales 32 are sequentially pulled apart until they overlap each other in front and back, thereby shielding the top curtain body 11 of the protective curtain unit 10, At this time, the support ribs 22 will be spaced apart from each other to support the unfolded protective curtain unit 10. In this way, the mechanism (such as a lead screw, not shown) covered by the protective curtain unit 10 can be For protection, the extended scales 31 and the standard scales 32 can also have a protective effect on the top curtain body 11 of the protective curtain unit 10 .

Through the above description, the advantages of this new model can be summarized as follows:

1. This case utilizes a design in which the second folds 125 of the side folding portions 122 of the side curtain bodies 12 extend downward and inward from one end of the first crease 114 of the top folding portion 112 of the top curtain body 11 , the second folds 125 of the side folding parts 122 will be separated from the first folds 114 of the top folding parts 112, and the folding connecting blocks 124 of the side folding parts 122 will not directly abut against Under the top folding blocks 113 of the top folding parts 112, compared with the conventional technology, in the process of unfolding and folding the protective curtain unit 10, the first creases of the top folding parts 112 are 114 will not rub against the second folds 125 of the side folding parts 122, which can effectively prevent the top folding parts 112 and the side folding parts 122 from breaking at these places, and prevent the cutting fluid (such as Pure water) leaks into the interior of the protective curtain unit 10, so that the mechanism below the protective curtain unit 10 will not rust.

2. The new scale unit 30 of the present invention uses the extended scale 31 to match the design of the standard scales 32. The extended scale 31 can be used in a one-to-many manner to directly cover the first four top folding parts 112 closest to the movable panel 21. (112Ⅰ) of the recessed space 115, even if the protective curtain unit 10 will be deployed most often at this end of the movable panel 21, the extended scale 31 will only form a gap with one of the standard scales 32 located at the front end. , and this gap is located outside the recessed spaces 115 of the first four top folding parts 112 (112Ⅰ). Compared with the conventional technology, the present invention can significantly reduce the waste material falling on the extended scales 31 due to cutting wafers. The chance of accidentally falling into the recessed spaces 115 of the first four top folding parts 112 (112I) prevents the protective curtain unit 10 from being easily cut by waste materials during the unfolding and folding process. This effectively prevents the cutting fluid (such as pure water) used during processing from leaking into the interior of the protective curtain unit 10 and preventing the mechanism below the protective curtain unit 10 from rusting.

3. The first shielding block 312 of the extended scale 31 of the scale unit 30 of the present invention uses the first inclined plate portion 314 to extend backward and downward from the first horizontal plate portion 313 to cooperate with the first overlapping portion. 315 is designed to extend backward and downward from the first inclined plate portion 314. When the protective curtain unit 10 is in the unfolded state, the first overlapping portion 315 of the first shielding block 312 of the extended scale 31 An elastic force will be generated that is always elastically pressed against one of the standard scales 32 located at the front end, allowing the two to overlap tightly.

Fourth, the scale unit 30 of the present invention utilizes the extended design of the extended scale 31. When the protective curtain unit 10 is in the folded state, the extended scale 31 will cover the top of the standard scales 32 to protect the standard scales 32 and reduce the chance of foreign objects invading between the standard scales 32.

To sum up, the new telescopic shield with wear-resistant protective curtain of the present invention not only allows the first crease of the top folding part of the top curtain body to be in contact with the side curtains during the unfolding and folding process. The second folds of the side folding parts of the body will not rub against each other, and can prevent the top folding parts and the side folding parts from breaking at these places, so the purpose of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this new patent.
