Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing equipment, and in particular to a fixture and auxiliary tooling for avoiding jamming of thin boards. Background Technology

[0002] As electronic products become increasingly miniaturized and integrated, the manufacturing precision and performance requirements for substrates are also rising. To meet the demand for thinner and lighter electronic products, the thickness of substrates is gradually decreasing, with the core layer thickness of some products as thin as 0.03mm. However, such ultra-thin boards face many challenges in processing, especially with the current horizontal processing capabilities. Thin boards are prone to problems such as jamming, deformation, and even breakage, leading to a significant increase in scrap rates.

[0003] In existing technologies, traditional processing fixtures are mainly designed for substrates of conventional thickness, and their clamping force, support structure, and positioning accuracy are difficult to adapt to the processing requirements of ultra-thin sheets. Specifically, when clamping ultra-thin sheets, traditional fixtures are prone to deformation or damage due to uneven or excessive clamping force. Simultaneously, due to the lack of effective support and positioning mechanisms, the sheets are prone to displacement or vibration during processing, further increasing processing difficulty and the risk of scrap. Furthermore, the design of existing fixtures does not fully consider the physical properties of ultra-thin sheets (such as flexibility and tensile strength), resulting in insufficient stability and precision support during processing.

[0004] Therefore, there is an urgent need to design a jig specifically for processing ultra-thin sheet metal parts in order to solve the problem of frequent scrapping of jig plates. Utility Model Content

[0005] The main purpose of this utility model is to provide a fixture and auxiliary tooling to avoid the jamming of thin plates, aiming to solve the technical problem that thin plates are easily jammed and frequently scrapped.

[0006] To achieve the above objectives, this utility model provides a fixture for avoiding the jamming of thin plates, including a plate body, including a clamping edge for clamping the thin plate; and a plurality of first clamping pieces, spaced apart from the clamping edge;

[0007] Several second clamps corresponding to the first clamp, each second clamp is set at a first preset distance on one side of the first clamp, the length of the second clamp is greater than that of the first clamp, and the second clamp is used to bend and snap into the worktable so that the thin plate is clamped between the first clamp and the second clamp.

[0008] Preferably, the clamping edge is provided with limiting latching pieces on both sides, and the length of the limiting latching pieces is greater than that of the first clamping piece.

[0009] Preferably, the first clip has a hollow hole.

[0010] Preferably, all the first clips and the second clips corresponding to the first clips are divided into N clamping arrays, and the distance between two adjacent clamping arrays is greater than or equal to a second preset distance, where N is a natural number greater than 1.

[0011] Preferably, the plate body has a mounting hole on the side near the clamping edge.

[0012] Preferably, the first preset distance is 20mm.

[0013] This utility model also provides an auxiliary tooling, including an operating table, a fixing component, and the aforementioned fixture for preventing the thin plate from jamming. The fixing component is disposed on the operating table and is used to press the plate body tightly against the surface of the operating table. The operating table is provided with a locking joint, which is used to engage the second clamping piece, so that the second clamping piece and the first clamping piece form an angle to fix the thin plate placed on the operating table.

[0014] Preferably, the fixing component includes a pressing clamp and a pressure plate. The pressing clamp is disposed on the operating table, and the pressure plate is connected to the pressing clamp. The pressing clamp drives the pressure plate to move up and down to press the plate body tightly against the surface of the operating table.

[0015] Preferably, the system also includes a partition disposed at the bottom of the worktable, the partition being used to hold tools for processing and fixing thin plates.

[0016] Preferably, the bottom surface of the partition at the bottom end is provided with a number of casters.

[0017] In the technical solution of this utility model, during the clamping of the thin plate using the fixture, the first clamping piece bends and inserts into the worktable, forming a space at a certain angle with the second clamping piece. The thin plate is then clamped within the space formed by the first and second clamping pieces, which have a certain elasticity. When the thickness of the thin plate fluctuates, the elastic bending amount of the second clamping piece automatically adjusts the clamping gap (dynamic adjustment range 0.01-0.05mm) to ensure that the clamping force is always within the safe threshold (5-10N / cm²), avoiding excessive pressure that could cause the plate to deform and jam. Furthermore, during the clamping of the thin plate, the edge force of the multiple spaced first and second clamping pieces changes from a continuous linear distribution to a discrete lattice distribution, significantly reducing microcracks or plastic deformation caused by excessive local stress.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Please refer to Figures 1 to 3 This utility model provides a fixture 10 to avoid jamming of thin plates, including a plate body 11, including a clamping edge 111 for clamping thin plates 30; a plurality of first clamping pieces 12, which are spaced apart from each other on the clamping edge 111; and a plurality of second clamping pieces 13 corresponding to the first clamping pieces 12. Each second clamping piece 13 is disposed at a first preset distance from one side of the first clamping piece 12, and the length of the second clamping piece 13 is greater than that of the first clamping piece 12. The second clamping pieces 13 are used to bend and insert into the worktable so that the thin plate 30 is clamped between the first clamping pieces 12 and the second clamping pieces 13.

[0029] In the technical solution of this utility model, during the process of using the jig to clamp the thin plate 30, the first clamping piece 12 bends and inserts into the worktable, forming a certain angle space with the second clamping piece 13. The thin plate 30 is clamped in the space formed by the first clamping piece 12 and the second clamping piece 13, which have a certain elasticity. When the thickness of the thin plate 30 fluctuates, the elastic bending amount of the second clamping piece 13 automatically adjusts the clamping gap (dynamic adjustment range 0.01-0.05mm) to avoid excessive pressure causing plate deformation and jamming. Moreover, during the clamping process of the multiple spaced first clamping pieces 12 and second clamping pieces 13, the edge force distribution changes from continuous linear distribution to discrete lattice distribution, which significantly reduces microcracks or plastic deformation caused by excessive local stress.

[0030] Please refer to Figures 1 to 3In this embodiment, limiting latching pieces 1111 are provided on both sides of the clamping edge 111, and the length of the limiting latching pieces 1111 is greater than that of the first clamping piece 12. The limiting latching pieces 1111 can prevent the clamped thin plate 30 from sliding out from both ends; furthermore, the first clamping piece 12 is provided with a hollow hole 121. The hollow hole 121 reduces production costs, and at the same time, the first clamping piece 12 has a certain buffer space during the process of contacting the uneven parts on the thin plate 30, reducing the deformation of the first clamping piece 12; furthermore, the plate body 11 is provided with a mounting hole 112 on the side near the clamping edge 111, and the plate body 11 can be mounted on the corresponding working platform through the mounting hole 112; furthermore, the first preset distance is 20mm. This distance parameter can ensure that the clamping force applied by the first clamping piece 12 and the second clamping piece 13 on the thin plate 30 is always within the safe threshold (5-10N / cm²).

[0031] Please refer to Figures 1 to 3 In this embodiment, all first clamping pieces 12 and the second clamping pieces 13 corresponding to the first clamping pieces 12 are divided into N clamping arrays. The distance between two adjacent clamping arrays is greater than or equal to a second preset distance, where N is a natural number greater than 1. In actual production applications, to save costs, multiple thin plates 30 are often clamped by one fixture. In order to prevent the multiple thin plates 30 from interfering with each other during clamping, a certain distance needs to be maintained between two adjacent thin plates 30. Therefore, each clamping array clamps one thin plate 30, and the second preset distance is 60mm. This ensures that adjacent thin plates 30 do not interfere with each other during stacking.

[0032] Please refer to Figures 1 to 3This utility model also provides an auxiliary tooling 20, including an operating table 21, a fixing component 22, and a fixture 10 to prevent the thin plate from jamming. The fixing component 22 is disposed on the operating table 21 and is used to press the plate 11 tightly onto the surface of the operating table 21. The operating table 21 is provided with a locking seam 211, which is used to lock the second clamping piece 13, so that the second clamping piece 13 and the first clamping piece 12 form an angle to fix the thin plate 30 placed on the operating table 21. The fixing component 22 includes a pressing clamp 221 and a pressure plate 222. The pressing clamp 221 is disposed on the operating table 21, and the pressure plate 222 is connected to the pressing clamp 221. The pressing clamp 221 drives the pressure plate 222 to move up and down to press the plate 11 tightly onto the surface of the operating table 21. When in use, move the handle of the pressing clamp 221 to move the pressure plate 222 upward, and insert the second clamp 13 of the fixture into the locking seam 211 to press the plate 11 onto the surface of the operating table 21. Move the handle of the pressing clamp 221 again to move the pressure plate 222 downward until it is pressed onto the surface of the plate 11 to complete the fixation of the fixture. Insert the edge of the thin plate 30 between the first clamp 12 and the second clamp 13. During this process, the height of the first clamp 12 can be adjusted by adjusting the up and down movement of the pressure plate 222 until the edge of the thin plate 30 is completely fixed.

[0033] Please refer to Figures 1 to 3 In this embodiment, the auxiliary tooling 20 also includes a partition 23 disposed at the bottom of the operating table 21. The partition 23 is used to place tools for processing and fixing the thin plate 30. Furthermore, the bottom surface of the partition 23 at the bottommost end is provided with several casters 231, which makes the entire auxiliary tooling 20 easy for workers to move.
