[0003] Currently, adhesive bonding or clamping or adsorption equipment are used to position plate-shaped parts. However, these methods are not accurate enough in positioning plate-shaped parts, or the positioning and processing of plate-shaped parts requires high usage and maintenance costs. It is difficult to ensure accurate positioning of plate-shaped parts while controlling the positioning and processing costs. Utility Model Content

[0004] This application aims to solve, at least to some extent, the technical problem of controlling the positioning and processing costs of plate-shaped parts while ensuring accurate positioning. To this end, this application provides a positioning tool.

[0005] This application provides a positioning tool, including:

[0006] The adsorption element is provided with a support part and an air passage hole, the two ends of the air passage hole are an air intake end and a connection end, respectively, and the air intake end is connected to the support part;

[0007] The negative pressure unit is provided with an inlet that communicates with the connection end;

[0008] The sealing element has a mating end that is inserted into the support portion, and a positioning hole extending to the mating end, the positioning hole being in communication with the suction end.

[0009] In some or more embodiments, the positioning tool includes a plurality of seals, and the support portion is provided with a plurality of frame-shaped grooves that are respectively inserted into the plurality of mating ends.

[0010] In some or more embodiments, the positioning holes of at least two of the seals are of different sizes, and the plurality of frame grooves are interconnected to form a grid-like groove.

[0014] In some or more embodiments, both the support body and the elastic part are cylindrical with a frame-shaped cross-section, and the support body and the elastic part are sealed together. The inner hole of the support body is configured as the mounting hole, and the inner hole of the elastic part is configured as the positioning hole.

[0015] In some or more embodiments, the support portion is provided with a plurality of adsorption holes located within the positioning hole and connected to the same air intake end, wherein the diameter of the adsorption holes is smaller than the diameter of the air passage hole.

[0016] In some or more embodiments, the adsorption element is provided with at least two interleaved and interconnected air passages, and at least one of the positioning holes is connected to the air intake end.

[0017] In some or more embodiments, the adsorption element is plate-shaped, and one plate surface of the adsorption element is configured as the support portion, and the plurality of connecting ends are spaced apart and connected to the sidewall of the adsorption element.

[0021] The beneficial effects provided by one or more embodiments of this application are as follows:

[0022] The support part of the adsorption component in the positioning tool can be used to place plate-shaped parts that need to be positioned. The two ends of the air passage in the adsorption component are the air intake end and the connection end, respectively. The air intake end is connected to the support part. The plate-shaped parts can be placed at the corresponding position of the air intake end of the support part. With the help of a negative pressure machine that connects the inlet and the connection end of the air passage, the gas between the plate-shaped parts and the support part flows from the air intake end to the connection end. The plate-shaped parts and the support part can be in a negative pressure or vacuum state. Under external pressure, the plate-shaped parts and the support part will be tightly adsorbed together, which can achieve the initial positioning of the plate-shaped parts. In the positioning tool, the mating end of the seal is inserted into the support. One end of the positioning hole of the seal extends to the mating end, and the positioning hole of the air passage is connected to the air intake end. A part of the plate-shaped part can be located in the positioning hole of the seal. The seal plays a limiting and sealing role for the plate-shaped part. In conjunction with the negative pressure machine, the positioning effect of the plate-shaped part is enhanced, ensuring effective positioning of the plate-shaped part. At the same time, the seal has little obstruction or interference to the plate-shaped part, allowing the part of the plate-shaped part that needs to be machined to protrude from the seal, which is convenient for machining the plate-shaped part. The seal and the support are inserted into each other, which also facilitates the replacement of the plate-shaped part that needs to be positioned and machined, and also helps to improve the machining convenience of the plate-shaped part. The overall structure is simple, which can ensure relatively accurate positioning of the plate-shaped part while controlling the positioning and machining cost of the plate-shaped part. To a certain extent, it solves the technical problem of not being able to ensure accurate positioning of the plate-shaped part while controlling the positioning and machining cost of the plate-shaped part.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0034] In related technologies, if plate-shaped parts are positioned using methods such as adhesive bonding during processing, positioning is inconvenient and prone to inaccuracy. Furthermore, the plate-shaped parts are prone to movement after positioning, hindering subsequent processing. Using clamping devices for positioning results in high positioning costs. There is a technical problem of controlling both the positioning accuracy and processing cost of plate-shaped parts. This application provides a positioning tool that can at least partially solve the above-mentioned technical problems.

[0035] The present application will now be described in conjunction with the accompanying drawings:

[0036] Figure 1 The present application shows a schematic diagram of the structure of a positioning tool in some or certain embodiments. Figure 2 A top view of an adsorption element in some or certain embodiments of this application is shown, with reference to... Figure 1 and Figure 2 This application provides a positioning tool, including:

[0037] The adsorption component 1 is provided with a support part 11 and an air passage 12. The two ends of the air passage 12 are an air intake end 121 and a connecting end 122, respectively, and the air intake end 121 is connected to the support part 11.

[0038] The negative pressure unit 2 is provided with an inlet 21 that is connected to the connection end 122.

[0039] The sealing element 3 has a mating end 31 that is inserted into the support part 11, and a positioning hole 32 extending to the mating end 31 at one end, and the suction end 121 is connected to the positioning hole 32.

[0040] The support part 11 of the adsorption component 1 in the positioning tool can be used to place the plate-shaped part 10 that needs to be positioned. The two ends of the air passage 12 in the adsorption component 1 are the air intake end 121 and the connecting end 122, respectively. The air intake end 121 is connected to the support part 11. The plate-shaped part 10 can be placed at the corresponding position of the air intake end 121 of the support part 11. With the cooperation of the negative pressure machine 2, which is connected to the connecting end 122 of the air passage 12 by the inlet 21, the gas between the plate-shaped part 10 and the support part 11 flows from the air intake end 121 to the connecting end 122. The plate-shaped part 10 and the support part 11 can be in a negative pressure or vacuum state. Under external pressure, the plate-shaped part 10 and the support part 11 will be tightly adsorbed together, which will play a preliminary positioning role for the plate-shaped part 10. In the positioning tool, the mating end 31 of the seal 3 is inserted into the support part 11. One end of the positioning hole 32 of the seal 3 extends to the mating end 31, and the suction end 121 of the air passage 12 is connected to the positioning hole 32. A portion of the plate-shaped part 10 can be located in the positioning hole 32 of the seal 3. The seal 3 plays a limiting and sealing role for the plate-shaped part 10. In conjunction with the negative pressure machine 2, it enhances the positioning effect of the plate-shaped part 10, ensuring effective positioning of the plate-shaped part 10. At the same time, the seal 3 has minimal obstruction and interference to the plate-shaped part 10. The part of the plate-shaped part 10 that needs to be machined can protrude from the seal 3, which facilitates the machining of the plate-shaped part 10. The seal 3 and the support part 11 are interlocked, which also facilitates the replacement of the plate-shaped part 10 that needs to be positioned. This also helps to improve the machining convenience of the plate-shaped part 10. The overall structure is simple and can ensure relatively accurate positioning of the plate-shaped part 10 while controlling the positioning machining cost of the plate-shaped part 10. To a certain extent, it solves the technical problem of not being able to ensure accurate positioning of the plate-shaped part 10 while controlling the positioning machining cost of the plate-shaped part 10.

[0041] It should be noted that a groove corresponding to the mating end 31 may be provided on the support part 11, and the groove is inserted into the mating end 31 to realize the insertion between the support part 11 and the sealing member 3.

[0042] For ease of understanding, in Figure 1 The image also shows a plate-shaped part 10, a portion of which is supported on the support 11 and located in the positioning hole 32 of the seal 3.

[0043] In some or more embodiments, the positioning tool includes a plurality of seals 3, and the support portion 11 is provided with a plurality of frame-shaped grooves 111 that are respectively inserted into a plurality of mating ends 31.

[0044] The mating ends 31 of the multiple seals 3 can respectively mate with the multiple frame-shaped grooves 111 on the support 11, which facilitates the batch positioning of multiple plate-shaped parts 10 and helps to improve the processing efficiency of multiple plate-shaped parts 10. Different frame-shaped grooves 111 on the support 11 can also mate with the seals 3, which facilitates the flexible positioning of the plate-shaped parts 10.

[0045] In some or more embodiments, the positioning holes 32 of at least two seals 3 are of different sizes, and multiple frame grooves 111 are interconnected to form a grid-like groove.

[0046] At least two sealing elements 3 have different sizes of positioning holes 32, and multiple frame grooves 111 are interconnected to form a grid-like groove. The sealing elements 3 with different sizes of positioning holes 32 can be inserted and matched with different positions of the grid-like groove according to the requirements, which can realize the positioning and connection of plate-shaped parts 10 of different sizes, and is conducive to improving the processing convenience of plate-shaped parts 10 of different sizes.

[0047] It should be noted that the positioning holes 32 of the two seals 3 are different in size. This could be due to different hole diameters, different lengths and widths, or different heights.

[0048] In some or more embodiments, the mating end 31 of the seal 3 may also be frame-shaped to facilitate the insertion and mating between the seal 3 and the frame groove 111.

[0049] Figure 3 This application shows a schematic diagram of the structure of a seal in some or certain embodiments, with reference to... Figure 3 In some or more embodiments, the seal 3 may include:

[0050] The supporting body 33 has a mating end 31 and a mounting hole 331 extending to the mating end 31.

[0051] The elastic part 34 is provided on the wall of the mounting hole 331 along the circumference of the mounting hole 331, and the positioning hole 32 is provided on the elastic part 34.

[0052] The support body 33 of the sealing element 3 can be used to insert and cooperate with the support part 11 to ensure the support and positioning effect of the plate-shaped part 10. The elastic part 34 is provided on the wall of the mounting hole 331 of the support body 33, and the positioning hole 32 is provided in the elastic part 34. The plate-shaped part 10 can be inserted into the positioning hole 32 located in the elastic part 34 and abut against the elastic part 34. The elastic part 34 can be squeezed to improve the sealing effect of the plate-shaped part 10, which can ensure a good positioning and sealing effect of the plate-shaped part 10. When used with the negative pressure machine 2, it can effectively improve the positioning accuracy of the plate-shaped part 10.

[0053] In some or more embodiments, both the support body 33 and the elastic part 34 are cylindrical and have a frame-shaped cross-section. The support body 33 and the elastic part 34 are sealed together. The inner hole of the support body 33 is configured as a mounting hole 331, and the inner hole of the elastic part 34 is configured as a positioning hole 32.

[0054] It is easy to process and prepare, and it is also easy to achieve the fit with the support part 11. The overall positioning effect of the plate-shaped part 10 is also good.

[0055] In some or more embodiments, the seal 3 may also be annular or an annular shape with an irregular cross-section. One end of the seal 3 is configured as a mating end 31. The support portion 11 may be provided with an annular groove that engages with the mating end 31. The shape of the annular groove may be adapted to the mating end 31. The inner diameter of the seal 3 may also be slightly smaller than the inner diameter of the mating groove. This ensures the engagement with the seal 3 and guarantees the sealing performance of the plate-shaped part 10.

[0056] Figure 4 The illustration shows a front view of an adsorption element in some or certain embodiments of this application. Figure 5 A side view of an adsorption element in some or certain embodiments of this application is shown, with reference to... Figure 2 , Figure 4 , 5 In some or more embodiments, the support portion 11 is provided with a plurality of adsorption holes 13 located in the positioning hole 32 and connected to the same air intake end 121, and the diameter of the adsorption hole 13 is smaller than the diameter of the air passage hole 12.

[0057] Multiple adsorption holes 13 are connected to the same suction end 121, and the diameter of the adsorption holes 13 is smaller than the space of the air passage 12. The adsorption holes 13 can play a certain pressurizing role, which can improve the positioning accuracy of the plate-shaped part 10.

[0058] It should be noted that the suction end 121 is connected to the positioning hole 32, so that the suction end 121 is surrounded by the annular groove or the frame groove 111. When the groove on the support part 11 is grid-shaped, multiple suction ends 121 can be surrounded by different frame grooves 111 respectively. The adsorption hole 13 connected to the same suction end 121 will be surrounded by the annular groove or the frame groove 111 surrounding the suction end 121.

[0059] In some or more embodiments, the support portion 11 may also be provided with a recess 15 corresponding to the adsorption hole 13 and surrounded by an annular groove or a frame-shaped groove 111. This facilitates the extraction of gas between the support portion 11 and the component.

[0060] In some or more embodiments, the adsorption member 1 is provided with at least two interleaved air passages 12, and at least one air intake end 121 is connected to the positioning hole 32.

[0061] The adsorption component 1 is provided with at least two staggered and interconnected air passages 12, and the air intake end 121 of at least one air passage 12 is connected to the positioning hole 32, which facilitates air extraction from the air passages 12 at different positions to position the plate-shaped part 10. This facilitates the positioning and processing of the plate-shaped part 10. The at least two air passages 12 can also be connected to the corresponding negative pressure machine 2 or multiple negative pressure inlets 21 of the negative pressure machine 2 to accelerate the air extraction and positioning effect.

[0062] In some or more embodiments, the adsorption element 1 is plate-shaped, and one plate surface of the adsorption element 1 is configured as a support portion 11, with a plurality of connecting ends 122 spaced apart and connected to the sidewall of the adsorption element 1.

[0063] The plate-shaped adsorption element 1 facilitates the support and positioning of the plate-shaped part 10, and one plate of the adsorption element 1 is configured as a support part 11. The connecting ends 122 of the multiple air passages 12 are spaced to the side wall of the adsorption element 1, which has a high space utilization rate and is also convenient to connect the negative pressure machine 2 from the side of the adsorption element 1.

[0064] It should be noted that the plate surface of the adsorption component 1 is the surface with the largest area of ​​the adsorption component 1, and the sidewall of the adsorption component 1 is the surface where there is a certain angle between the adsorption component 1 and the plate surface. When the adsorption component 1 is a cuboid structure, the sidewall can be the side of the adsorption component 1; when the adsorption component 1 is a circular plate structure, the sidewall can be the peripheral wall of the adsorption component 1. The adsorption component 1 can also be set as a block or column, etc., as needed, and can also achieve the purpose of supporting parts.

[0065] In some or more embodiments, the positioning tool further includes:

[0066] Multiple switch structures (not shown in the figure) are connected to the adsorption member 1 and are used to control the switches of multiple connection terminals 122 respectively.

[0067] The addition of a switch structure allows the connection end 122 of the air vent 12 to be switched on and off, enabling the flexible use of one or more air vents 12 for air extraction as needed, thus improving the flexibility of the positioning tool.

[0068] In some or all embodiments, the switch structure may be a blockage or a plug.

[0069] In some or more embodiments, when the adsorption member 1 is cuboid, the connecting ends 122 of the plurality of air passages 12 can be respectively disposed on two adjacent sidewalls of the adsorption member 1, and the axes of the plurality of air passages 12 can be parallel to the two sidewalls of the adsorption member 1. This facilitates the processing of the positioning tool.

[0070] In some or more embodiments, the adsorption member 1 is further provided with at least two spaced connection holes 14.

[0071] The adsorption component 1 is provided with at least two spaced connection holes 14, which can be engaged with fasteners to position and install the adsorption component 1 onto a fixed device or processing platform. This facilitates the positioning and installation of the adsorption component 1.

[0072] In some or more embodiments, at least one connecting hole 14 is an oblong hole. This facilitates the adjustment and fixing of the adsorption member 1 to the appropriate position, thereby facilitating the processing of the plate-shaped part 10.

[0073] In some or more embodiments, the adsorption member 1 may be plate-shaped, the connecting hole 14 may penetrate two parallel plate surfaces of the adsorption member 1, and the fastener may be bolt, screw, nut, or spring.

[0074] It should be noted that the parallelism involved in this application refers to absolute parallelism in relative geometry, and a deviation of 0° to 5° is allowed.
