Description

Technical Field

[0001] This application relates to the field of negative pressure adsorption, and in particular to templates, negative pressure switching fixtures, components and workbenches with switchable negative pressure zones. Background Technology

[0002] In the electronics manufacturing industry, especially in the production of LCD panels, touch screens, and flexible circuit boards, templates are often needed to hold products in place. When working on a table, the tabletop can be used as a template.

[0003] However, as product sizes change, different vacuum zone templates need to be replaced when switching between products of different sizes. This not only results in low production efficiency, but also leads to greater costs due to the different vacuum zone templates.

[0004] Specifically, this production method of changing templates requires different vacuum zones to accommodate products of different sizes, resulting in high production costs. Furthermore, switching between different sizes requires disassembling and reassembling the templates, and readjusting their position, levelness, and flatness, leading to low production efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a template, a negative pressure switching fixture, components, and a workbench with switchable negative pressure zones.

[0057] The following is combined with Figures 1 to 14 The template, negative pressure switching fixture, components and workbench of the switchable negative pressure area are described in detail.

[0058] In one embodiment of this application, a template with switchable negative pressure areas includes a negative pressure transmission channel and a plate body. The plate body is provided with a basic negative pressure adsorption area and an expanded adsorption area. The basic negative pressure adsorption area is used to obtain negative pressure adsorption force through the negative pressure transmission channel. The plate body is also provided with a basic connecting pipe connecting the basic negative pressure adsorption area and an expanded connecting pipe connecting the expanded adsorption area. The basic connecting pipe has a basic connecting end located on the outer surface of the plate body, and the expanded connecting pipe has an expanded connecting end located on the outer surface of the plate body. The basic connecting end has a closed state and a conductive state connected to the expanded connecting end. The aforementioned template with switchable negative pressure areas, through the combined design of the basic negative pressure adsorption area and the expanded adsorption area, allows the basic connecting end to have a closed state and a conductive state connected to the expanded connecting end. This cleverly achieves rapid adjustment of at least two negative pressure adsorption areas. Only one template with switchable negative pressure areas is needed to perform negative pressure adsorption on products of different sizes. Therefore, different sizes of products do not require template replacement; the conductive state of the basic connecting end can be adjusted directly. As a result, it has advantages such as low implementation cost, fast switching of negative pressure adsorption areas, high production efficiency, and ease of promotion and application. It is especially suitable for negative pressure adsorption of non-single products.

[0059] In one embodiment, a negative pressure zone switchable component 300, such as Figure 1 As shown, it includes a template 100 with switchable negative pressure zones and a negative pressure switching fixture 200. Combined with... Figure 2 and Figure 3 As an example, the switchable negative pressure region template 100 is used to provide a negative pressure adsorption region for the object to be processed, thereby defining the position of the object during processing; as an example, the negative pressure switching fixture 200 is used to switch the negative pressure adsorption region of the switchable negative pressure region template 100. As an example, the negative pressure switching fixture 200 is detachably connected to the switchable negative pressure region template 100 to switch the negative pressure adsorption region of the switchable negative pressure region template 100. Wherein, the switchable negative pressure region template 100 is any of the switchable negative pressure region templates 100 described in any embodiment, and can also be simply referred to as a template; the negative pressure switching fixture 200 is any of the negative pressure switching fixtures 200 described in any embodiment, and can also be simply referred to as a fixture. Figure 4 and Figure 5This structural design, through the coordinated design of the basic negative pressure adsorption area 105 and the expanded adsorption area in the switchable negative pressure area template 100, allows the basic connecting end 151 of the switchable negative pressure area template 100 to have both a closed state and a conductive state connected to the expanded connecting end. This cleverly achieves rapid adjustment of at least two negative pressure adsorption areas. Only one switchable negative pressure area template 100 is needed to perform negative pressure adsorption on products of different sizes. With the help of a negative pressure switching fixture 200, the negative pressure adsorption area of ​​the switchable negative pressure area template 100 can be switched. Therefore, for products of different sizes, there is no need to change the template; the conductive state of the basic connecting end 151 can be directly adjusted. Thus, it has the advantages of low implementation cost, fast switching of negative pressure adsorption areas, high production efficiency, and easy promotion and application. It is especially suitable for negative pressure adsorption of non-single products, that is, suitable for negative pressure adsorption of multiple products of different specifications.

[0060] As an example, combined Figures 2 to 12 The negative pressure switching fixture 200 is detachably connected to the negative pressure area switchable template 100, so that the basic communication end 151 of the negative pressure area switchable template 100 has an expanded communication end that is connected to the negative pressure area switchable template 100 through the connecting pipe of the negative pressure switching fixture 200. Examples of the negative pressure switching fixture 200 and the negative pressure area switchable template 100 are given below.

[0061] In one embodiment, a template 100 with switchable negative pressure zones is as follows: Figure 4 and Figure 5 As shown, it includes a plate 170, combined with Figure 6The template 100 with switchable negative pressure area further includes a negative pressure transmission channel 160; the plate body 170 is provided with a basic negative pressure adsorption area 105 and an expanded adsorption area, the basic negative pressure adsorption area 105 is used to obtain negative pressure adsorption force through the negative pressure transmission channel 160; the plate body 170 is also provided with a basic connecting pipe 150 connecting the basic negative pressure adsorption area 105 and an expanded connecting pipe connecting the expanded adsorption area; the basic connecting pipe 150 has a basic connecting end 151 located on the outer surface of the plate body 170, and the expanded connecting pipe has an expanded connecting end located on the outer surface of the plate body 170; the basic connecting end 151 has a closed state and a conductive state connected to the expanded connecting end. This structural design, through the coordinated design of the basic negative pressure adsorption region 105 and the expanded adsorption region, allows the basic connecting end 151 to have both a closed state and a conductive state connected to the expanded connecting end. This cleverly achieves rapid adjustment of at least two negative pressure adsorption regions. Only one template 100 with switchable negative pressure regions is needed to perform negative pressure adsorption on products of different sizes. Therefore, different sizes of products do not require template replacement; the conductive state of the basic connecting end 151 can be adjusted directly. As a result, it has advantages such as low implementation cost, fast switching of negative pressure adsorption regions, high production efficiency, and ease of promotion and application. It is especially suitable for negative pressure adsorption of non-single products.

[0062] In each embodiment, the basic negative pressure adsorption region 105 is used to obtain negative pressure adsorption force through the negative pressure transmission channel 160. As an example, the basic negative pressure adsorption region 105 is used to connect to an external negative pressure generating device, such as a vacuum pump, through the negative pressure transmission channel 160 to obtain negative pressure adsorption force, that is, to obtain negative pressure. Figure 4 and Figure 6 The negative pressure transmission channel 160 is connected to a negative pressure generating device or its pipeline through its first end 161 to obtain negative pressure adsorption force; if necessary, the negative pressure transmission channel 160 can also be connected to a negative pressure generating device or its pipeline through its second end 162 to obtain negative pressure adsorption force.

[0063] In each embodiment, the basic connecting end 151 has a closed state and a conductive state connected to the extended connecting end. For example, if there is one extended connecting end, the basic connecting end 151 has a closed state and a conductive state connected to the extended connecting end; or, if there are two extended connecting ends, the basic connecting end 151 has a closed state and a conductive state connected to either of the extended connecting ends; as an example, the basic connecting end 151 also has a conductive state connected to all of the extended connecting ends; in one embodiment, the basic connecting end 151 has a conductive state connected to any of the extended connecting ends, that is, for the technical solution with N extended connecting ends, the basic connecting end 151 has a closed state and a conductive state connected to any of the extended connecting ends, and also has a conductive state connected to any 2, any 3... any N-1, or all of the extended connecting ends. This structural design enables flexible switching between the basic negative pressure adsorption region 105 and the extended adsorption region.

[0064] In each embodiment, the expanded adsorption region is relative to the basic negative pressure adsorption region 105, and in one embodiment, the number of expanded adsorption regions is at least two. As an example, such as... Figure 5 As shown, the number of expanded adsorption regions is four. Outside the basic negative pressure adsorption region 105, there are a first negative pressure adsorption region 101, a second negative pressure adsorption region 102, a third negative pressure adsorption region 103, and a fourth negative pressure adsorption region 104. All the negative pressure adsorption regions, including the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, the fourth negative pressure adsorption region 104, and the basic negative pressure adsorption region 105, together form the maximum adsorption range 180. The other number of negative pressure adsorption regions follow the same pattern and will not be described in detail.

[0065] In each embodiment, the number of expanded connecting channels is the same as the number of expanded adsorption regions. There are N expanded adsorption regions, corresponding to N expanded connecting channels, and each expanded connecting channel corresponds one-to-one with each expanded adsorption region; that is, each expanded connecting channel corresponds to one expanded adsorption region, and each expanded adsorption region corresponds to one expanded connecting channel. In one embodiment, the number of expanded adsorption regions is at least two, the number of expanded connecting channels is the same as the number of expanded adsorption regions, and each expanded connecting channel corresponds one-to-one with each expanded adsorption region; the basic connecting end 151 has a conductive state that connects to any of the expanded connecting ends.

[0066] In each embodiment, the template 100 with switchable negative pressure area is provided with an assembly hole 190 on the plate 170, which can be used to fix the plate 170, for example, by fixing the plate 170 to the base through the assembly hole 190.

[0067] In each embodiment, each of the expanded connecting conduits has an expanded connecting end located on the outer surface of the plate 170. As an example, the basic connecting end 151 and the expanded connecting end are disposed on the side or adsorption surface of the plate 170. Figure 4 and Figure 6 As shown, the number of expanded connecting pipes and their expanded connecting ends are both four; the expanded connecting pipes include a first connecting pipe 110, a second connecting pipe 120, a third connecting pipe 130, and a fourth connecting pipe 140; the expanded connecting ends include a first connecting end 111, a second connecting end 121, a third connecting end 131, and a fourth connecting end 141. It is understood that in other embodiments, the number of expanded connecting pipes and their expanded connecting ends can also be one, two, three, five, six, or more. This structural design allows the switchable negative pressure template 100 to quickly switch between different negative pressure adsorption areas, thereby enabling rapid negative pressure adsorption of products of different sizes. Therefore, different sized products do not require template replacement; only the conductivity state of the basic connecting end 151 needs to be adjusted.

[0068] In one embodiment, the negative pressure adsorption range of the basic negative pressure adsorption region 105 and each of the expanded adsorption regions shows an increasing and covering trend, that is, the negative pressure adsorption range of the basic negative pressure adsorption region 105 and each of the expanded adsorption regions shows an increasing and covering trend; according to the increasing and covering trend, the basic connecting end 151 is optionally connected to N of the expanded connecting pipes arranged in sequence, wherein N is greater than 1 and not greater than the total number of the expanded connecting ends. As an example, the basic negative pressure adsorption region 105 has the smallest negative pressure adsorption range, and the negative pressure adsorption ranges of other extended adsorption regions are larger than those of the basic negative pressure adsorption region 105. Furthermore, the negative pressure adsorption ranges of the other extended adsorption regions increase sequentially. Therefore, it is said that the negative pressure adsorption ranges of the basic negative pressure adsorption region 105 and each of the extended adsorption regions exhibit a sequential increasing trend. Additionally, the extended adsorption region with the smallest negative pressure adsorption range covers the negative pressure adsorption range of the basic negative pressure adsorption region 105, and the negative pressure adsorption range of the subsequent extended adsorption region sequentially covers the negative pressure adsorption range of the preceding extended adsorption region. Therefore, it is said that the negative pressure adsorption ranges of the basic negative pressure adsorption region 105 and each of the extended adsorption regions exhibit a sequential covering trend. Overall, it is said that the negative pressure adsorption ranges of the basic negative pressure adsorption region 105 and each of the extended adsorption regions exhibit a sequential increasing and covering trend.

[0069] like Figure 5 As shown, N is 4. The negative pressure adsorption ranges of the basic negative pressure adsorption region 105, the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, and the fourth negative pressure adsorption region 104 increase sequentially. Furthermore, the negative pressure adsorption range of the first negative pressure adsorption region 101 covers the negative pressure adsorption range of the basic negative pressure adsorption region 105, the negative pressure adsorption range of the second negative pressure adsorption region 102 covers the negative pressure adsorption range of the first negative pressure adsorption region 101, and the negative pressure adsorption range of the third negative pressure adsorption region 103 covers the negative pressure adsorption range of the second negative pressure adsorption region 102. The negative pressure adsorption range is defined as follows: the negative pressure adsorption range of the fourth negative pressure adsorption region 104 covers the negative pressure adsorption range of the third negative pressure adsorption region 103. It is understood that in each embodiment, the negative pressure adsorption range refers to the outer contour range of the negative pressure adsorption area. The negative pressure adsorption region is the area with adsorption force generated by negative pressure. When the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, the fourth negative pressure adsorption region 104, and the basic negative pressure adsorption region 105 all have negative pressure, the negative pressure adsorption range is the adsorption range jointly formed by the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, and the basic negative pressure adsorption region 105. Other embodiments follow the same principle and will not be elaborated further.

[0070] In one embodiment, such as Figure 5 As shown, the basic negative pressure adsorption region 105 and the negative pressure adsorption ranges of each of the extended adsorption regions form a sequentially covering rectangle; in other embodiments, depending on product requirements, the basic negative pressure adsorption region 105 and the negative pressure adsorption ranges of each of the extended adsorption regions can also form concentric circles or sequentially covering regular polygons. This structural design facilitates the use of the switchable negative pressure region template 100 for products of the same type but with different sizes, enabling rapid adjustment of at least two types of negative pressure adsorption regions.

[0071] In one embodiment, such as Figure 6As shown, the negative pressure transmission channel 160 is directly connected to the basic negative pressure adsorption area 105; the basic connecting pipe 150 can be directly connected to the negative pressure transmission channel 160, or it can be connected to the negative pressure transmission channel 160 through the basic negative pressure adsorption area 105. In other embodiments, the negative pressure transmission channel 160 can also be connected to the basic negative pressure adsorption area 105 through the basic connecting pipe 150. This structural design ensures that the basic connecting pipe 150, the negative pressure transmission channel 160, and the basic negative pressure adsorption area 105 remain connected, thereby allowing negative pressure to be transmitted to other pipes through the basic connecting pipe 150. As an example, when the basic connecting pipe 150 is connected to the first connecting pipe 110, such as... Figure 6 As shown, the negative pressure transmission channel 160, the basic negative pressure adsorption region 105, the basic connecting pipe 150, the first connecting pipe 110, and the first negative pressure adsorption region 101 are sequentially connected so that the negative pressure of the negative pressure transmission channel 160 is transmitted to the first negative pressure adsorption region 101 through the basic negative pressure adsorption region 105. As an example, it can be understood that the larger the negative pressure adsorption range, the greater the negative pressure adsorption force obtained by the negative pressure transmission channel 160 in the basic negative pressure adsorption region 105, so that the negative pressure of the negative pressure transmission channel 160 can effectively act on the expanded adsorption region, for example... Figure 6 The first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, and the fourth negative pressure adsorption region 104 are shown.

[0072] In one embodiment, such as Figure 4 As shown, at least one of the basic connecting pipe 150, the expanded connecting pipe, and the negative pressure transmission channel 160 is a channel formed in the plate 170. As an example, the basic connecting pipe 150, the expanded connecting pipe, or the negative pressure transmission channel 160 is a channel formed in the plate 170. As an example, the basic connecting pipe 150, the expanded connecting pipe, and the negative pressure transmission channel 160 are all channels formed in the plate 170. Figure 4 In the illustrated embodiment, the expanded connecting pipe includes a first connecting pipe 110, a second connecting pipe 120, a third connecting pipe 130, and a fourth connecting pipe 140. Other embodiments follow the same principle and will not be described in detail.

[0073] Or, in one embodiment, such as Figure 7As shown, the plate 170 includes a first plate 171 and a second plate 172. At least one of the basic connecting pipe 150, the expanded connecting pipe, and the negative pressure transmission channel 160 is a pipe disposed in the first plate 171 and the second plate 172. As an example, the basic connecting pipe 150, the expanded connecting pipe, or the negative pressure transmission channel 160, disposed in the first plate 171 and the second plate 172, can be implemented using plastic or metal pipes. As an example, the basic connecting pipe 150, the expanded connecting pipe, and the negative pressure transmission channel 160 are all pipes disposed in the first plate 171 and the second plate 172.

[0074] As an example, in a specific application, the switchable negative pressure zone template 100 can be used with connecting pipes to connect the basic connecting pipe 150 to one or more expansion connecting pipes; that is, connecting pipes can be used to connect the basic connecting end 151 to one or more expansion connecting ends. Exemplarily, the connecting pipe can be a common double-ended pipe or a multi-ended pipe, with one end connected to the basic connecting end 151 and the other ends connected to the expansion connecting ends.

[0075] To facilitate the reliable and rapid use of the switchable negative pressure zone template 100, in one embodiment, this application also provides a negative pressure switching fixture 200, such as... Figure 8 As shown, it includes a fixture body 250; the negative pressure switching fixture 200 has a connecting structure and a positioning mounting part 260 on the fixture body 250; the connecting structure has a connecting pipe; combined with Figure 1 and Figure 2The fixture body 250 is detachably connected to the negative pressure area switchable template 100 in any embodiment via the positioning and mounting part 260, so that the basic communication end 151 of the negative pressure area switchable template 100 has an expanded communication end that is connected to the negative pressure area switchable template 100 via the connecting pipe. This structural design provides a dedicated negative pressure switching fixture 200 for the switchable negative pressure region template 100. It can assist in quickly connecting the basic negative pressure adsorption region 105 and the expanded adsorption region of the switchable negative pressure region template 100, thereby realizing the rapid adjustment of at least two negative pressure adsorption regions and improving the switching efficiency of the negative pressure adsorption region of the switchable negative pressure region template 100. This allows the switchable negative pressure region template 100 to quickly perform negative pressure adsorption on products of different sizes. Therefore, different sizes of products do not need to be replaced with different templates. The conductivity state of the basic connection end 151 of the switchable negative pressure region template 100 can be adjusted directly through the negative pressure switching fixture 200. Therefore, it has the advantages of low implementation cost, fast switching speed of negative pressure adsorption region, high production efficiency and easy promotion and application. It is especially suitable for negative pressure adsorption of non-single products.

[0076] In one embodiment, such as Figure 8 As shown, the fixture body 250 has a prism shape and at least two contact surfaces. Each contact surface serves as a connection structure, and a connecting groove is provided on the contact surface as a connecting pipe. The fixture body 250 is detachably connected to the negative pressure area switchable template 100 via the positioning mounting part 260, so that one of the contact surfaces is sealed to the plate body 170 of the negative pressure area switchable template 100, and the basic connecting end 151 is connected to at least one extended connecting end via the connecting groove. The lengths of each connecting groove are different to connect different numbers of extended connecting ends.

[0077] As an example, the negative pressure switching fixture 200 has a positioning and mounting part 260 on the fixture body 250, and the fixture body 250 is screwed onto the template 100 or its plate 170 that can switch negative pressure areas through the positioning and mounting part 260.

[0078] Figure 8 In the illustrated embodiment, the jig body 250 has a quadrangular prism shape and four contact surfaces, which serve as four connecting structures to correspond to... Figure 4 or Figure 6 The diagram shows a structural design with four connecting pipes and their connecting ends. In this embodiment, the contact surfaces include a first contact surface 210, a second contact surface 220, a third contact surface 230, and a fourth contact surface 240. Other embodiments follow the same principle and will not be described in detail.

[0079] Specifically, if Figure 9 As shown, the fixture body 250 has a first contact surface 210, and the first contact surface 210 has a first connecting groove 211. The length of the first connecting groove 211, i.e., the first length L1, is greater than or equal to the first distance D1 between the basic connecting end 151 and the first connecting end 111, or the first length L1 is the sum of the radius of the basic connecting end 151, the radius of the first connecting end 111, and the hole spacing between the basic connecting end 151 and the first connecting end 111. (Combined with...) Figure 4 and Figure 5 With this structural design, the first contact surface 210 is sealed and installed on the side of the plate 170 of the switchable negative pressure area template 100 during use, so that the basic connecting pipe 150 connects to the first connecting end 111 of the first connecting pipe 110 through its basic connecting end 151 and the first connecting groove 211, thereby making the first negative pressure adsorption area 101 have a negative pressure adsorption function, that is, both the first negative pressure adsorption area 101 and the basic negative pressure adsorption area 105 have a negative pressure adsorption function.

[0080] Similarly, such as Figure 10 As shown, the fixture body 250 also has a second contact surface 220, and the second contact surface 220 has a second connecting groove 221. The length of the second connecting groove 221, i.e., the second length L2, is greater than or equal to the second distance D2 between the basic connecting end 151 and the second connecting end 121, or the second length L2 is the sum of the radius of the basic connecting end 151, the radius of the second connecting end 121, and the hole spacing between the basic connecting end 151 and the second connecting end 121. (Combined with...) Figure 4 and Figure 5 This structural design allows the second contact surface 220 to be sealed and installed on the side of the plate 170 of the switchable negative pressure area template 100 during use. Alternatively, during switching, other contact surfaces, such as the first contact surface 210, can be disassembled and the second contact surface 220 installed. This allows the basic connecting pipe 150 to connect to the second connecting end 121 of the second connecting pipe 120 via its basic connecting end 151 and the second connecting groove 221. Consequently, the second negative pressure adsorption area 102 exhibits negative pressure adsorption, meaning both the second negative pressure adsorption area 102 and the basic negative pressure adsorption area 105 possess negative pressure adsorption capabilities. Specifically, Figure 10 In the embodiment shown, the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, and the basic negative pressure adsorption region 105 all have negative pressure adsorption effects.

[0081] Similarly, such as Figure 11As shown, the fixture body 250 also has a third contact surface 230, and the third contact surface 230 has a third connecting groove 232. The length of the third connecting groove 232, i.e., the third length L3, is greater than or equal to the third distance D3 between the basic connecting end 151 and the third connecting end 131, or the third length L3 is the sum of the radius of the basic connecting end 151, the radius of the third connecting end 131, and the hole spacing between the basic connecting end 151 and the third connecting end 131. (Combined with...) Figure 4 and Figure 5 This structural design allows the third contact surface 230 to be sealed and installed on the side of the plate 170 of the switchable negative pressure area template 100 during use. Alternatively, during switching, other contact surfaces, such as the first contact surface 210 or the second contact surface 220, can be disassembled, and then the third contact surface 230 can be installed. This allows the basic connecting pipe 150 to connect to the third connecting end 131 of the third connecting pipe 130 via its basic connecting end 151 and the third connecting groove 232. This enables the third negative pressure adsorption area 103 to have a negative pressure adsorption function, meaning that both the third negative pressure adsorption area 103 and the basic negative pressure adsorption area 105 have a negative pressure adsorption function. Specifically, Figure 11 In the embodiment shown, the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, and the basic negative pressure adsorption region 105 all have negative pressure adsorption effects.

[0082] Similarly, such as Figure 12 As shown, the fixture body 250 also has a third contact surface 230, and the third contact surface 230 has a third connecting groove 232. The length of the third connecting groove 232, i.e., the third length L3, is greater than or equal to the third distance D3 between the basic connecting end 151 and the fourth connecting end 141, or the third length L3 is the sum of the radius of the basic connecting end 151, the radius of the fourth connecting end 141, and the hole spacing between the basic connecting end 151 and the fourth connecting end 141. (Combined with...) Figure 4 and Figure 5 This structural design allows the third contact surface 230 to be sealed and installed on the side of the plate 170 of the switchable negative pressure area template 100 during use. Alternatively, during switching, other contact surfaces, such as the first contact surface 210 or the second contact surface 220, can be disassembled, and then the third contact surface 230 can be installed. This allows the basic connecting pipe 150 to connect to the fourth connecting end 141 of the fourth connecting pipe 140 via its basic connecting end 151 and the third connecting groove 232. Consequently, both the fourth negative pressure adsorption area 104 and the basic negative pressure adsorption area 105 have a negative pressure adsorption function. Specifically, Figure 12In the embodiment shown, the first negative pressure adsorption region 101, the second negative pressure adsorption region 102, the third negative pressure adsorption region 103, the fourth negative pressure adsorption region 104 and the basic negative pressure adsorption region 105 all have negative pressure adsorption effects, forming a maximum adsorption range 180.

[0083] As can be seen from the above description, the negative pressure switching fixture 200, in conjunction with the template 100 that can switch negative pressure areas, has the advantages of being easy to install and easy to use, which helps to increase the speed of switching negative pressure adsorption areas, thereby improving production efficiency.

[0084] In one embodiment, a worktable 400 with switchable negative pressure zones is described as follows: Figure 13 As shown, it includes a base 200 and a template 100 with switchable negative pressure areas. The template 100 with switchable negative pressure areas is disposed on the base 200, combined with... Figure 14 The negative pressure transmission channel 160 of the switchable negative pressure region template 100 is used to connect to the negative pressure generating device 600. The switchable negative pressure region template 100 is any of the switchable negative pressure region templates described in any embodiment. In other embodiments, the switchable negative pressure region workbench 400 may further include any of the negative pressure switching fixtures 200 described in any embodiment; that is, the switchable negative pressure region workbench 400 includes any of the negative pressure region switching components 300 described in any embodiment. In other embodiments, such as... Figure 14 As shown, the workbench 400 with switchable negative pressure zones may include the negative pressure generating device 600.

[0085] It is understood that the workbench 400 with switchable negative pressure area has a template 100 or a component 300 with switchable negative pressure area, and therefore has the beneficial technical effects of having the template 100 or the component 300 with switchable negative pressure area, which will not be elaborated here.

[0086] It should be noted that other embodiments of this application also include a template, negative pressure switching fixture, components and workbench formed by combining the technical features of the above embodiments, which can be implemented as a switchable negative pressure area.

[0087] The technical features of the above embodiments can be combined in any way.
