Description

Scale-type retractable guard

The invention relates to a telescopic protective cover, in particular to a scale-type telescopic protective cover.

As shown in FIGS. 1 , 2 and 3 , a scale-type retractable protective cover for a processing machine (e.g., a wafer cutting machine, not shown) is known, comprising an expandable or retractable protective curtain 1, a support module 2 connected to the protective curtain 1, and a scale module 3 for shielding the top side of the protective curtain 1. The protective curtain 1 includes a top curtain body 101 and two side curtain bodies 102 connected to both sides of the top curtain body 101. The top curtain body 101 has a number of ridges 103 arranged in a length direction X and extending along a transverse direction Y, and a number of top folding parts 104 connected between the ridges 103. When the protective curtain 1 is unfolded, each top folding part 104 can define a concave space 105. The supporting module 2 includes a movable plate 201 arranged at the front end of the protective curtain 1, a fixed plate 202 arranged at the rear end of the protective curtain 1, and a number of supporting ribs 203 arranged in the protective curtain 1 and fixed to the corresponding ridges 103. As shown in FIGS. 2 , 3 and 4 , the scale module 3 includes a number of scales 301 of the same specification. One of the scales 301 at the front end is fixed to the movable plate 201 , and the remaining scales 301 are connected to the corresponding ridges 103 and fixed to the tops of the corresponding supporting ribs 203 .

Thus, as shown in FIGS. 4 and 5 , 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 101 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 101 of the protective curtain 1.

When the scale-type retractable shield is deployed, the protective curtain 1 is most often deployed at the end of the movable panel 201 closest to the tool of the processing machine. Therefore, the first few scales 301 adjacent to the movable panel 201 are also most often pulled open. However, when the scale-type retractable shield is deployed, each scale 301 is responsible for directly shielding the concave space 105 of each top folding portion 104 in a one-to-one manner. Therefore, the concave spaces 105 of the first few top folding portions 104 adjacent to the movable panel 201 need to be covered by the same number of first few scales 301. To cover it, although the first few scales 301 can cover the top of the concave space 105 of the first few top folds 104, a gap will still be formed between these scales 301, causing the waste materials of the cut wafers to fall on these scales 301, which may easily fall into the concave space 105 of the first few top folds 104 from the gaps between these scales 301, so that the protective curtain 1 may be cut by the waste materials during the process of unfolding and folding, causing the cutting fluid (such as pure water) used in the processing to leak into the interior of the protective curtain 1, causing the mechanism under the protective curtain 1 to rust.

Therefore, the object of the present invention is to provide a scale-type retractable shield that can overcome at least one disadvantage of the prior art.

Therefore, the novel scale-type retractable shield includes a protective curtain unit, a support unit, and a scale unit.

The protective curtain unit can be transformed between an unfolded state and a folded state along a length direction, and includes a top curtain body, which has a number of ridges arranged in the length direction and extending along a transverse direction, and a number of top folding parts extending along the transverse direction, each top folding part is connected between any two adjacent ridges, when the protective curtain unit is in the unfolded state, the ridges are separated from each other, the top folding parts are unfolded, and each top folding part defines a concave space, when the protective curtain unit is in the folded state, the ridges are close to each other, and the top folding parts are folded.

The supporting unit includes a movable plate arranged at the front end of the protective curtain unit, and a plurality of supporting ribs, each of which is connected to a corresponding peak ridge and is located under the top curtain body.

The scale unit is used to cover the top side of the protective curtain unit, and includes an extended scale and a plurality of standard scales. The extended scale is fixed to the movable panel. When the protective curtain unit is in the unfolded state, the extended scale directly covers the concave space of at least two of the top folded parts closest to the movable panel, and the standard scales respectively cover the concave space of the remaining top folded parts outside the at least two of the top folded parts. The standard scales are connected to the corresponding peak ridges located on both sides of the remaining top folded parts, and the standard scales are fixed to the corresponding supporting ribs, and the corresponding supporting ribs are connected to the corresponding peak ridges.

The utility model is that the scale unit of the novel type utilizes the design of the extended scale in conjunction with the standard scales. The extended scale can directly cover the concave space of the front top folds closest to the movable panel in a one-to-many manner. Even if the protective curtain unit is most often unfolded at this end of the movable panel, the extended scale will only form a gap with one of the standard scales at the front end, and the gap is still located at the front top folds. In addition to the concave space of the overlapping parts, the present invention can greatly reduce the chance that the waste materials dropped on the extended scales during the cutting operation accidentally fall into the concave spaces of the first few top folded parts, so that the protective curtain unit will not be easily cut by the waste materials during the process of unfolding and folding, and can effectively prevent the cutting fluid (such as pure water) used in processing from leaking into the interior of the protective curtain unit, thereby preventing the mechanism under the protective curtain unit from rusting.

6, 7, and 8, which are an embodiment of the novel scale-type retractable shield 100, the scale-type retractable shield 100 comprises a protective curtain unit 10, a support unit 20, and a scale unit 30. In this embodiment, the scale-type retractable shield 100 can be used in a processing machine (such as a wafer cutting machine, not shown).

The protective curtain unit 10 can be transformed between an unfolded state (see FIGS. 8 and 9 ) and a folded state (see FIGS. 11 and 12 ) along a length direction X, and includes a top curtain body 11 and two side curtain bodies 12. In the present embodiment, the protective curtain unit 10 is formed by folding a piece of fabric.

The top screen body 11 has a plurality of ridges 111 arranged in a length direction X and extending along a transverse direction Y, and a plurality of top folding portions 112 extending along the transverse direction Y. Each top folding portion 112 is connected between any two adjacent ridges 111.

The side screen bodies 12 are respectively connected to the left and right opposite sides of the top screen body 11 along the length direction X and extend downward. Each side screen body 12 has a number of side ridges 121 arranged in the length direction X and corresponding to the peak ridges 111, and a number of side folding parts 122 corresponding to the top folding parts 112. Each side folding part 122 is connected between any two adjacent side ridges 121.

As shown in FIG8 , when the protective curtain unit 10 is in the unfolded state, the ridges 111 are separated from each other, the top folding portions 112 are unfolded, each top folding portion 112 defines a concave space 113, the side ridges 121 are separated from each other, and the side folding portions 122 are unfolded. As shown in FIG11 , when the protective curtain unit 10 is in the folded state, the ridges 111 are close to each other, the top folding portions 112 are folded, the side ridges 121 are close to each other, and the side folding portions 122 are folded.

As shown in FIGS. 7 and 8 , the supporting unit 20 includes a movable plate 21 disposed at the front end of the protective curtain unit 10 , a fixed plate 23 disposed at the rear end of the protective curtain unit 10 , and a plurality of supporting ribs 22 .

As shown in Figures 8, 9, and 10, the top side of each supporting rib 22 is connected to one of the corresponding peak ridges 111, and the left and right opposite ends of each supporting rib 22 are connected to the corresponding side ridges 121 of the side curtain bodies 12. The supporting ribs 22 are arranged in the protective curtain unit 10 and are located below the top curtain body 11.

As shown in FIGS. 7 , 9 and 10 , the scale unit 30 is used to cover the top side of the protective curtain unit 10 and includes an extended scale 31 and a number of standard scales 32.

In this embodiment, the extended scale 31 has a first mounting block 311 fixed to the movable panel 21, and a first shielding block 312 extending rearward from the first mounting block 311. The first shielding block 312 of the extended scale 31 has a first horizontal plate portion 313 connected to the first mounting block 311, a first inclined plate portion 314 extending rearward and downward obliquely from the first horizontal plate portion 313, and a first overlapping portion 315 extending rearward and downward obliquely from the first inclined plate portion 314.

In this embodiment, each standard scale 32 has a second mounting block 321 and a second shielding block 322 extending backward from the second mounting block 321. The second shielding block 322 of each standard scale 32 has a second horizontal plate portion 323 connected to the second mounting block 321, and a second overlapping portion 324 extending backward and downward from the second horizontal plate portion 323.

When the protective curtain unit 10 is in the unfolded state, the extended scale 31 directly covers the concave space 113 of at least two of the top folded portions 112 closest to the movable panel 21, and the standard scales 32 respectively cover the concave spaces 113 of the remaining top folded portions 112 outside the at least two of the top folded portions 112, and the standard scales 32 are connected to the corresponding peak ridges 111 located on both sides of the remaining top folded portions 112, and the standard scales 32 are fixed to the corresponding supporting ribs 22, and the corresponding supporting ribs 22 are connected to the corresponding peak ridges 111.

In the present embodiment, when the protective curtain unit 10 is in the unfolded state, the extended scale 31 directly covers the concave spaces 113 of four of the top folded portions 112 (for clear marking, additionally marked as 112Ⅰ) closest to the movable panel 21, and the standard scales 32 respectively cover the concave spaces 113 of the remaining top folded portions 112 (for clear marking, additionally marked as 112Ⅱ) outside the four top folded portions 112. It can be understood that in other variations of the present embodiment, the number of concave spaces 113 of the top folded portions 112 (112Ⅰ) directly covered by the extended scale 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. 9 and 10 , 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 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 FIGS. 11 and 12 , 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 first shielding block 312 of the extended scale 31 is located above the second shielding blocks 322 of the standard scales 32, 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 second shielding blocks 322 of any two adjacent standard scales 32 are adjacent to each other, and the second shielding blocks 322 of the standard scales 32 overlap each other.

Thus, as shown in FIGS. 9 and 10 , when the processing machine is to perform processing, the movable plate 21 can be driven forward to unfold the protective curtain unit 10 from the folded state (see FIGS. 11 and 12 ) to the unfolded state, so that the extended scales 31 and the standard scales 32 that were originally overlapped are sequentially pulled apart to overlap each other front and back, and the protective curtain unit 10 is unfolded. At this time, the supporting ribs 22 will be spaced apart from each other to support the unfolded protective curtain unit 10, so that the mechanism (such as a lead screw, not shown) shielded by the protective curtain unit 10 can be protected, and the extended scales 31 and the standard scales 32 can also protect the top curtain body 11 of the protective curtain unit 10.

Through the above description, the advantages of the present invention can be summarized as follows:

1. The scale unit 30 of the present invention utilizes the design of the extended scale 31 in conjunction with the standard scales 32. The extended scale 31 can directly cover the concave space 113 of the first four top folds 112 (112I) closest to the movable panel 21 in a one-to-many manner. Even if the protective curtain unit 10 is most often unfolded at this end of the movable panel 21, the extended scale 31 will only form a gap with one of the standard scales 32 at the front end, and the gap is still located at the first four top folds 112 (112 Compared with the prior art, the present invention can significantly reduce the chance of waste materials dropped onto the extended scale 31 during the cutting of wafers and accidentally falling into the concave space 113 of the first four top folding parts 112 (112Ⅰ), so that the protective curtain unit 10 will not be easily cut by the waste materials during the unfolding and folding process, and can effectively prevent the cutting fluid (such as pure water) used in the processing from leaking into the interior of the protective curtain unit 10, thereby avoiding the rusting of the mechanism under the protective curtain unit 10.

Second, the first shielding block 312 of the extended scale 31 of the scale unit 30 of the present invention utilizes the first inclined plate portion 314 to extend obliquely backward and downward from the first horizontal plate portion 313, and cooperates with the design that the first overlapping portion 315 extends obliquely 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 will generate an elastic force that is constantly elastically pressed toward one of the standard scales 32 located at the front end, so that the two are tightly overlapped together.

3. 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.

In summary, the scale-type retractable protective cover of the present invention can not only effectively reduce the chance of waste materials generated during processing accidentally falling into the concave space of the front folded parts of the protective curtain unit, but also prevent the protective curtain unit from being easily cut by waste materials during the process of unfolding and folding, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
