Description

Technical Field

[0001] This utility model relates to the field of substrate processing auxiliary equipment technology, specifically a substrate drilling positioning auxiliary device. Background Technology

[0002] In the field of substrate processing, drilling is one of the key processes. The positioning accuracy and clamping stability of the substrate directly determine the drilling quality, while the ease of operation and environmental cleanliness affect the processing efficiency and the workload of the operators.

[0003] A search revealed existing technology (application number: CN202021737948.2), which describes a "circuit board drilling positioning device." While this utility model can achieve basic positioning and clamping functions, in practical applications, existing devices mostly rely on lead screws to drive and adjust the position, combined with spring clamping and bolt limiting to achieve clamping. This not only involves cumbersome adjustment steps but also lacks a unified positioning benchmark, resulting in poor adaptability to substrates of different sizes. Furthermore, the spring clamping structure is prone to elasticity decay due to long-term use, leading to substrate displacement during drilling, affecting drilling accuracy, and increasing the scrap rate. Existing devices do not have a dedicated debris collection structure, causing drilling debris to accumulate on the workbench or substrate surface, requiring additional cleaning procedures. This pollutes the working environment, consumes operator time, increases auxiliary workload, and reduces overall processing efficiency.

[0004] Therefore, there is an urgent need for a substrate drilling positioning auxiliary device that can provide a unified positioning reference, adapt to substrates of different sizes and clamp stably, while also having a convenient debris collection function, which can reduce operation steps and improve drilling accuracy and processing efficiency.

The lower surface of the first pressing plate is uniformly connected to the upper surfaces of a plurality of first pressing pads.

[0011] As a further description of the above technical solution:

[0012] The upper surface of the first pressure plate is provided with protrusions on both sides, and the protrusions are connected to the two ends of the first pull rod on the opposite side. The side of the first pressure plate near the limiting post is connected to one side of the limiting plate. The limiting plate is provided with a through hole in the middle, and a mounting block is provided on one side of the limiting plate.

[0013] As a further description of the above technical solution:

[0014] The second pressing assembly includes a hinge plate, the upper end of which is hinged to one end of the second pressing plate, and the other end of the second pressing plate is connected to one end of a locking screw, the other end of which is placed inside the upper part of the locking block.

The upper surface of the second pressure plate is provided with protrusions on both sides, and the protrusions are connected to the two ends of the second pull rod on the opposite side.

[0019] This utility model has the following beneficial effects:

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a substrate drilling positioning auxiliary device, including a positioning plate 1. The positioning plate 1 is square, and one side of the positioning plate 1 is connected to a connecting ear 5. The connecting ear 5 is L-shaped and is used for mounting the positioning plate 1. An opening is provided in the middle of one side of the positioning plate 1. One corner of the upper surface of the positioning plate 1 is connected to the lower surface of a positioning right angle 2. A first pressing component 3 is provided on the upper surface of the positioning plate 1 near the positioning right angle 2. The first pressing component 3 is used for limiting the substrate. A second pressing component 4 is slidably provided on the side of the positioning plate 1 away from the first pressing component 3. The second pressing component 4 is used to adapt to substrates of different sizes.

[0033] In this embodiment, the first pressing component 3 and the second pressing component 4 constitute a substrate drilling positioning auxiliary device according to this application.

[0034] It should also be noted that the substrate drilling in this application can be through-hole drilling of printed circuit boards, blind via drilling of flexible substrates, micro-via drilling of ceramic substrates, etc. Figure 1 In this embodiment, the substrate drilling is described as a through-hole drilling of a printed circuit board. Of course, other types of substrate drilling can also adopt a similar structure, which will not be described in detail below.

[0035] Understandable Figure 1The diagram only schematically illustrates some of the components included in the positioning aid; the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, positioning aids can also include, compared to Figure 1 More or fewer parts.

[0036] In addition, in this embodiment, there are four connecting ears 5, which are fixed at the corners on both sides of the positioning plate 1. The width of the opening in the middle of one side of the positioning plate 1 is adapted to the collection box 6. The positioning plate 1 is installed on the workbench through the connecting ears 5. One corner of the substrate is initially positioned by fitting the positioning right angle 2. The first pressing component 3 fixes one side of the substrate. The second pressing component 4 slides to adjust the position to adapt to substrates of different sizes, so as to realize the fixed installation of the device, provide a substrate positioning reference, and meet the initial positioning requirements of substrates of different sizes.

[0037] Specifically, the upper surface of the positioning plate 1 has multiple through holes in the middle, and a collection box 6 is slidably disposed in the opening on one side of the positioning plate 1. The collection box 6 is used for collecting debris. The lower end of the limiting post 7 is connected to the side of the upper surface of the positioning plate 1 near the positioning right angle 2, and multiple locking grooves are provided on both sides of the upper end of the limiting post 7.

[0038] In this embodiment, drilling debris falls into the collection box 6 through the through hole. The limiting post 7, together with the limiting plate of the first pressing component 3, locks the drilling debris, collects the debris, avoids debris accumulation, improves the locking stability of the first pressing component 3, and prevents substrate displacement.

[0039] Example 2:

[0040] A first pressing component 3 is provided based on embodiment 1.

[0041] Specifically, the first pressing assembly 3 includes a first pressing plate 301, one end of which is hinged to the upper end of the mounting block 304, and the lower end of the mounting block 304 is bolted to the side wall of the positioning plate 1. The lower surface of the first pressing plate 301 is uniformly connected to the upper surfaces of a plurality of first pressing pads 302.

[0042] In a preferred embodiment, the first pressing plate 301 rotates around the hinge of the mounting block 304, and the first pressing pad 302 contacts the upper surface of the substrate and presses one side of the substrate. The rubber pressing pad avoids damaging the surface of the substrate.

[0043] Specifically, the upper surface of the first pressing plate 301 is provided with protrusions on both sides, and the protrusions are connected to the two ends of the first pull rod 303 on the opposite side. The side of the first pressing plate 301 near the limiting post 7 is connected to one side of the limiting plate. The limiting plate is provided with a through hole in the middle, and a mounting block 304 is provided on one side of the limiting plate.

[0044] In this embodiment, pulling the first pull rod 303 causes the first pressing plate 301 to rotate via the protrusion, and the limiting plate through the through hole is fitted into the limiting post 7, which facilitates the operator to quickly rotate the first pressing plate 301 and realize the cooperation between the first pressing component 3 and the limiting post 7.

[0045] Example 3:

[0046] A second pressing component 4 is provided based on embodiment 2.

[0047] Specifically, the second pressing assembly 4 includes a hinge plate 401, the upper end of which is hinged to one end of the second pressing plate 402, and the other end of the second pressing plate 402 is connected to one end of the locking screw 403, the other end of which is placed inside the upper part of the locking block 404.

[0048] With this configuration, the second holding plate 402 rotates around the upper end of the hinge plate 401, and the locking screw 403 is placed in the groove of the locking block 404, pressing the other side of the base plate. The locking screw and the locking block cooperate to achieve initial fixation.

[0049] Specifically, one end of the transmission rod 405 is connected to the lower end of the hinge plate 401. The other end of the transmission rod 405 is threaded and passes through the lower end of the locking block 404. Locking nuts are connected to the end of the locking screw 403 away from the second pressure plate 402 and the end of the transmission rod 405 away from the hinge plate 401.

[0050] When the second pressing component 4 is slidable, the transmission rod 405 moves along the threaded hole of the locking block 404. After adjustment, the locking nut is tightened to fix the position of the second pressing component 4, restricting its sliding and rotation, and improving the clamping stability.

[0051] Specifically, the lower surface of the second pressure plate 402 is uniformly connected to the upper surface of the second pressure pad 407, and protrusions are provided on both sides of the upper surface of the second pressure plate 402, with the protrusions connected to the two ends of the second pull rod 406 on the opposite side.

[0052] In this embodiment, pulling the second lever 406 causes the second pressing plate 402 to rotate via the protrusion, and the second pressing pad 407 contacts the upper surface of the substrate, making it easy for the operator to quickly rotate the second pressing plate 402. The rubber pressing pad avoids damage to the substrate, and achieves stable pressing on the other side of the substrate.

[0053] In actual use, the device is first installed on the drilling table via the connecting lug 5. Then, one corner of the substrate is aligned with the inside of the positioning right angle 2 for initial positioning. After it is tightly attached, the first pull rod 303 is pulled. The first pull rod 303 drives the first pressing plate 301 to rotate along the hinge through the protrusion, so that the first pressing pad 302 on the lower surface of the first pressing plate 301 contacts the upper surface of the substrate. At this time, the through hole in the middle of the limiting plate passes through the upper end of the limiting post 7. After pressing is completed, the mounting block 304 is pushed to insert the end of the mounting block 304 into the locking groove at the upper end of the limiting post 7 for locking. Then, the locking nut at the threaded end of the locking block 404 is rotated. Then, the second pressing assembly 4 is pulled to slide along the lower part of the positioning plate 1. After it moves to the appropriate position, the locking nut is rotated to restrict the second pressing assembly. After moving 4, the second pull rod 406 is pulled. The second pull rod 406 drives the second pressure plate 402 to rotate along the hinge through the protrusion, so that the second pressure pad 407 on the lower surface of the second pressure plate 402 presses the upper surface of the substrate. At this time, the end of the second pressure plate 402 away from the hinge plate 401 is connected to the locking screw 403 and is inserted into the upper part of the locking block 404. Then, the locking nut is rotated to restrict the movement of the second pressure plate 402. After clamping, drilling is performed. After drilling, the debris falls into the inside of the collection box 6 through the through hole in the middle of the upper surface of the positioning plate 1. After drilling is completed, the first pressure component 3 and the second pressure component 4 are unlocked and the substrate is taken out. Then, the second pressure component 4 is pulled back to the end of the positioning plate 1. At this time, the collection box 6 can be pulled out to clean the debris inside the collection box 6.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
