Description

Technical Field

[0001] The present invention relates to the technical field of flying wing radiators, and more particularly to a double-sided flying wing radiator processing device. Background Art

[0002] Wing heat sinks are manufactured using a special tool (shovel) to scrape individual fins from a sheet of aluminum or copper and then erect them upright. This technology transcends the thickness-to-length ratio limitations of conventional heat sinks, enabling the creation of high-density fins. Heat sinks manufactured using the flying wing process integrate the fins and base, eliminating any interfacial impedance issues and achieving excellent heat dissipation. Because they are formed in one go, the profile's heat dissipation performance is maintained at 100% of its original value, resulting in widespread use in the photovoltaic industry, electric vehicles, inverters, communications products, and other high-power applications.

[0038] refer to Figures 1 to 11 , the embodiments of the present invention are described in detail below. It should be emphasized that the following description is only exemplary and is not intended to limit the scope of the present invention and its application.

[0039] refer to Figure 1 and Figure 2 The double-sided continuous flying wing device of an embodiment of the present invention includes a double-sided rack mechanism 1, a feeding mechanism 2, a clamping mechanism 3, a flying wing mechanism 4, a guide mechanism 5 and a power mechanism 6.

[0040] refer to Figure 5 The power source of the power mechanism 6 is a motor, hydraulic pressure or air pressure. For example, the power source of the power mechanism 6 is a motor, and the power mechanism 6 includes a wing motor 61 and a crank 62. The output shaft of the wing motor 61 is connected to the crank 62, and the crank 62 is connected to the double-sided rack mechanism 1.

[0041] refer to Figure 5 The power mechanism 6 drives the double-sided rack mechanism 1. Under the guidance of the guide mechanism 5, the double-sided rack mechanism 1 drives the clamping mechanism 3 and the wing mechanism 4 to clamp and scrape the base material 7 transported by the feeding mechanism 2, thereby obtaining a heat dissipation accessory with fins on both sides.

[0042] The material clamping mechanism 3 includes a first material clamping mechanism 3A and a second material clamping mechanism 3B, and the wing mechanism 4 includes a first swinging wing mechanism 4A and a second swinging wing mechanism 4B.

[0043] refer to Figure 2The double-sided rack mechanism 1 includes two sections, namely a first section 1A with teeth on both sides and a second section 1B with teeth on both sides; specifically, the first section 1A and the second section 1B are both provided with teeth on two opposite sides. In an embodiment of the present invention, the first section 1A and the second section 1B are both a straight rack. The feeding mechanism 2 is used to convey the substrate 7, so that the substrate 7 moves between the first clamping mechanism 3A and the second clamping mechanism 3B, and so that the substrate 7 moves between the first swinging wing mechanism 4A and the second swinging wing mechanism 4B. Specifically, when the clamping mechanism 3 and the wing mechanism 4 are both released, the feeding mechanism 2 conveys the substrate 7 forward so as to process the unprocessed parts of the substrate 7.

[0044] The double-sided rack mechanism 1 is connected to the guide mechanism 5. The guide mechanism 5 is used to guide the double-sided rack mechanism 1. The power mechanism 6 is connected to the double-sided rack mechanism 1. The power mechanism 6 drives the double-sided rack mechanism 1. In this way, the double-sided rack mechanism 1 can move along the path defined by the guide mechanism 5. For example, refer to Figure 1 and Figure 11 A slider unit 11 is provided on the double-sided rack mechanism 1, and the guide mechanism 5 is a slide rail. The slider unit 11 is connected to the slide rail, so that the double-sided rack mechanism 1 can move along the slide rail; wherein the slider unit 11 includes multiple sliders.

[0045] In the embodiment of the present invention, the first clamping mechanism 3A and the second clamping mechanism 3B are two symmetrical mechanisms.

[0046] refer to Figure 5 The first clamping mechanism 3A includes a first clamping unit 3A1 and a first rotating push-up unit 3A2. The first clamping unit 3A1 is used to press the substrate 7. The first rotating push-up unit 3A2 is engaged with the first surface 1B1 of the second section 1B to achieve rotation; specifically, the first rotating push-up unit 3A2 is provided with a gear engaged with the first surface 1B1, and when the double-sided rack mechanism 1 moves, the first rotating push-up unit 3A2 rotates. The first rotating push-up unit 3A2 contacts the first clamping unit 3A1 to support the first clamping unit, so that the first clamping unit 3A1 can press or loosen the substrate 7; specifically, the first rotating push-up unit 3A2 is an eccentric rotating shaft, and when the first rotating push-up unit 3A2 rotates, different parts of it will contact the first clamping unit 3A1, thereby causing the first clamping unit 3A1 to move.

[0047] refer to Figure 5The second clamping mechanism 3B includes a second clamping unit 3B1 and a second rotating push-up unit 3B2. The second clamping unit 3B1 is used to press the substrate 7. The second rotating push-up unit 3B2 is engaged with the second surface 1B2 of the second section 1B to achieve rotation; specifically, the second rotating push-up unit 3B2 is provided with a gear engaged with the second surface 1B2, and when the double-sided rack mechanism 1 moves, the second rotating push-up unit 3B2 rotates. The second rotating push-up unit 3B2 contacts the second clamping unit 3B1 to support the second clamping unit 3B1, so that the second clamping unit 3B1 can press or loosen the substrate 7; specifically, the second rotating push-up unit 3B2 is an eccentric rotating shaft, and when the second rotating push-up unit 3B2 rotates, different parts of it will contact the second clamping unit 3B1, thereby causing the second clamping unit 3B1 to move.

[0048] In the embodiment of the present invention, the first swinging wing mechanism 4A and the second swinging wing mechanism 4B are also two symmetrical mechanisms.

[0049] refer to Figure 5 The first swinging wing mechanism 4A includes a first swing arm 4A1 and a first scraping unit 4A2. The first scraping unit 4A2 is used to scrape one surface of the substrate 7. The first swing arm 4A1 is engaged with the first surface 1A1 of the first section 1A; specifically, the first swing arm 4A1 is provided with teeth distributed in an arc shape, and when the double-sided rack mechanism 1 performs linear motion, it can drive the first swing arm 4A1 engaged therewith to swing. The first swing arm 4A1 is connected to the first scraping unit 4A2 to drive the first scraping unit 4A2 to swing; specifically, the first scraping unit 4A2 is fixed to the first swing arm 4A1, so that the first scraping unit 4A2 can swing along with the first swing arm 4A1.

[0050] refer to Figure 5 The second swinging wing mechanism 4B includes a second swing arm 4B1 and a second scraping unit 4B2. The second scraping unit 4B2 is used to scrape the other side of the substrate 7. The second swing arm 4B1 is engaged with the second side 1A2 of the first section 1A; specifically, the second swing arm 4B1 is provided with teeth distributed in an arc shape. When the double-sided rack mechanism 1 performs linear motion, it can drive the second swing arm 4B1 engaged therewith to swing. The second swing arm 4B1 is connected to the second scraping unit 4B2 to drive the second scraping unit 4B2 to swing; specifically, the second scraping unit 4B2 is fixed to the second swing arm 4B1, so that the second scraping unit 4B2 can swing along with the second swing arm 4B1.

[0051] The double-sided rack mechanism 1 enables the first and second clamping mechanisms 3A and 3B to clamp the substrate 7, followed by the first and second swinging wing mechanisms 4A and 4B to swing the substrate 7. During operation, the double-sided rack mechanism 1 first causes the clamping mechanism 3 to clamp the substrate 7, and then causes the swinging wing mechanism 4 to swing the substrate 7. Specifically, this is achieved via the first and second segments 1A and 1B of the double-sided rack mechanism 1. In this embodiment of the present invention, the first segment 1A causes the swinging wing mechanism 4 to swing the substrate 7, while the second segment 1B causes the clamping mechanism 3 to clamp the substrate 7.

[0052] refer to Figure 1 and Figure 5 At the beginning, it is necessary to load the material so that the long strip substrate 7 passes through the feeding mechanism 2, so that the substrate 7 can be transported to the clamping mechanism 3 and the flying wing mechanism 4. The double-sided continuous flying wing device of the embodiment of the present invention includes the following processes when working: feeding, clamping, flying, retracting, and releasing.

[0053] Feeding: The feeding mechanism 2 works to move the substrate 7 forward, with one section of the substrate 7 located between the first clamping mechanism 3A and the second clamping mechanism 3B, and the other section of the substrate 7 located between the first swinging wing mechanism 4A and the second swinging wing mechanism 4B.

[0054] Clamping: The power mechanism 6 works to make the double-sided rack mechanism 1 move linearly. The second section 1B of the double-sided rack mechanism 1 causes the first rotating top opening unit 3A2 and the second rotating top opening unit 3B2 to rotate, thereby causing the first clamping unit 3A1 and the second clamping unit 3B1 located on both sides of the substrate 7 to clamp the substrate 7.

[0055] Flying wing: The double-sided rack mechanism 1 continues to move, the clamping mechanism 3 keeps clamping the substrate 7, and the first section 1A of the double-sided rack mechanism 1 causes the first rotary arm 4A1 and the second rotary arm 4B1 to swing, thereby causing the first scraping unit 4A2 and the second scraping unit 4B2 located on both sides of the substrate 7 to move along an arc, scraping both sides of the substrate 7.

[0056] Retraction: After the wing scraping is completed, the power mechanism 6 causes the double-sided rack mechanism 1 to move in the reverse direction, and the first scraping unit 4A2 and the second scraping unit 4B2 withdraw from the substrate 7.

[0057] Release: the power mechanism 6 causes the double-sided rack mechanism 1 to move in the reverse direction, and the first clamping unit 3A1 and the second clamping unit 3B1 leave the substrate 7 , thereby releasing the substrate 7 .

[0058] Subsequently, the feeding mechanism 2 works and feeds the material forward, so that the processed area on the substrate 7 leaves the area where the wing mechanism 4 is located, and the unprocessed area on the substrate 7 enters the area where the wing mechanism 4 is located, repeating the aforementioned clamping, winging, retracting, and releasing processes.

[0059] According to the above, the double-sided rack mechanism 1 causes the first clamping unit 3A1 of the first clamping mechanism 3A and the second clamping unit 3B1 of the second clamping mechanism 3B to clamp the substrate 7, and then causes the first scraping unit 4A2 of the first swinging wing mechanism 4A and the second scraping unit 4B2 of the second swinging wing mechanism 4B to swing, thereby performing double-sided scraping on the substrate 7. Compared with the prior art that realizes scraping through structures such as synchronous drive, couplings, and multi-stage hinged mechanisms, the embodiment of the present invention simplifies the transmission mechanism, so that the movement of the double-sided scraping is synchronized, and the scraping motion trajectory of the first scraping unit 4A2 and the second scraping unit 4B2 has a slight curvature, which is beneficial to the initial scraping of the tool and can retain the initial part of the fin, thereby ensuring the consistency of the processed heat dissipation accessories. In addition, the motion trajectory of the scraping unit has a slight curvature, so that the scraped fins have a certain curvature and a larger heat dissipation area.

[0060] The present invention will be further described below.

[0061] refer to Figure 7-9 The first swing arm 4A1 includes a first swing portion 4A11, a first rotational connection portion 4A12, and a first bent portion 4A13. The first swing portion 4A11 engages with the first surface 1A1 of the first segment 1A. For example, the first swing portion 4A11 has a fan-shaped shape and is provided with arc-shaped teeth for engaging with the first surface 1A1 of the first segment 1A. The first rotating connection part 4A12 is rotatably arranged and connects the first swinging part 4A11 and the first bending part 4A13, the first scraping unit 4A2 is arranged on the first bending part 4A13, and the first avoidance hole is opened on the first bending part 4A13; for example, the first rotating connection part 4A12 is rotatably arranged on the shell, the first swinging part 4A11 is fixedly connected to the first rotating connection part 4A12 and can drive the first rotating connection part 4A12 to rotate, the first bending part 4A13 is fixedly connected to the first rotating connection part 4A12, and the first bending part 4A13 is bent toward the feeding direction of the substrate 7 to form a V shape, and the first scraping unit 4A2 is fixed on the first bending part 4A13 and can rotate with the first bending part 4A13; since the first swinging part 4A11 swings during operation, the movement trajectory of the first scraping unit 4A2 is arc-shaped, that is, the first scraping unit 4A2 can swing back and forth, thereby scraping the substrate 7.

[0062] Similar to first swing arm 4A1, second swing arm 4B1 includes a second swing portion 4B11, a second pivoting connection portion 4B12, and a second bent portion 4B13. Second swing portion 4B1 engages with second surface 1A2 of first segment 1A. For example, second swing portion 4B1 is fan-shaped and has arc-shaped teeth arranged thereon for engagement with second surface 1A2 of first segment 1A. The second rotating connection part 4B12 is rotatably arranged and connects the second swinging part 4B11 and the second bending part 4B13, the second scraping unit 4B2 is arranged on the second bending part 4B13, and the second avoiding hole is opened on the second bending part 4B13; for example, the second rotating connection part 4B12 is rotatably arranged on the shell, the second swinging part 4B11 is fixedly connected to the second rotating connection part 4B12 and can drive the second rotating connection part 4B12 to rotate, the second bending part 4B13 is fixedly connected to the second rotating connection part 4B12, the second scraping unit 4B2 is fixed on the second bending part 4B13 and can rotate with the second bending part 4B13, and the second bending part 4B13 is bent toward the feeding direction of the substrate 7 to form a V shape; since the second swinging part 4B11 swings during operation, the movement trajectory of the second scraping unit 4B2 is arc-shaped, that is, the second scraping unit 4B2 can swing back and forth, thereby scraping the substrate 7.

[0063] refer to Figure 7-9 One end of the second curved portion 4B13 passes through the first avoidance hole in the first curved portion 4A13, and the substrate 7 passes through both the second avoidance hole in the second curved portion 4B13 and the first avoidance hole in the first curved portion 4A13. At this point, the first scraping units 4A2 and the second scraping units 4B2 are alternately arranged. The first scraping unit 4A2 performs wing processing on the side of the substrate 7 closest to the second rotary arm 4B1, while the second scraping unit 4B2 performs wing processing on the side of the substrate 7 adjacent to the first rotary arm 4A1. In other words, the rotation axes of the first and second rotary arms 4A1, 4B1, and the first and second scraping units 4A2, 4B2 are located on opposite sides of the substrate, respectively.

[0064] Please refer to further Figure 10 The motion trajectories of the first and second scraping units 4A2, 4B2 are shown. Based on these trajectories, the first and second scraping units 4A2, 4B2 respectively machine convexly curved tooth blades on both sides of the substrate 7. These convexly curved tooth blades are thicker at the base and thinner at the top. Based on the thermodynamic principle of rib-wall heat transfer, this structure improves heat conduction efficiency. Therefore, the wing heat sink machined using the present invention has a higher heat dissipation efficiency. Furthermore, the thicker base of the tooth blades enhances the connection strength between the tooth blades and the base.

[0065] As can be seen from the above, the first scraping unit 4A2 and the second scraping unit 4B2 perform flying in a swinging manner, which simplifies the structure of the flying mechanism, thereby avoiding errors caused by multi-stage transmission and ensuring product consistency.

[0066] refer to Figure 7 The first scraping unit 4A2 and the second scraping unit 4B2 have the same structure and are symmetrically arranged, with a space between them for the substrate 7 to pass through. Both units include a cutter 421, a cutter holder 422, and a locking member 423. The cutter 421 is used to scrape the substrate; the cutter holder 422 is used to secure the cutter 421; and the locking member 423 is used to lock the cutter 421 to the cutter holder 422. The cutter 421 is mounted on the cutter holder 422, and the locking member 423 is connected to the cutter holder 422 to lock the cutter 421, making it easier to replace the cutter. Specifically, a notch 4221 is provided on the tool seat 422, and the tool 421 is placed in the notch 4221, which is conducive to reliably fixing the tool 421 so that the tool 421 can support the tool seat 422 when scraping the substrate; after the tool 421 is placed on the tool seat 422, for example, in the notch 4221, the side surface of the tool 421 and the surface of the tool seat 422 form a groove that is larger at the top and smaller at the bottom, that is, a wedge-shaped groove is formed, and the locking component 423 is set in the groove, which is convenient for locking the tool 421.

[0067] The first section 1A and the second section 1B may also be structures provided with teeth distributed in an arc shape.

[0068] refer to Figure 4 The feeding mechanism 2 includes a feeding motor 21, a worm 22, a turbine 23, and multiple pairs of rollers 24. For example, the feeding mechanism 2 includes four pairs of rollers 24. The feeding motor 21 meshes with the worm 22, which in turn meshes with the turbine 23. The turbine 23 is located at one end of the roller 24 to drive the roller 24 to rotate. The roller 24 is provided with knurling 241. The distance between the two rollers 24 is sufficient for the substrate 7 to pass through. The elongated substrate 7 is positioned between the two rollers 24, with its two opposing sides contacting the knurling on the rollers 24. As the feeding motor 21 rotates, it drives the worm 22 horizontally via a gear transmission. The worm 22 then drives the turbines 23 located on either side of the worm 22 vertically, causing the two opposing rollers 24 to rotate in opposite directions. As the rollers 24 rotate, the friction of the knurling causes the substrate 7 to move linearly between the two rollers 24, thereby achieving feeding. A male and female connection structure is set at the ends of the two base materials 7, so that the two base materials 7 can be connected end to end, thereby realizing continuous feeding and completing continuous flying. During the flying process, there is no need to interrupt the equipment to load the material, which can improve the processing efficiency.

[0069] According to the above, a transmission mechanism of a worm and a turbine is adopted, and rollers 24 with knurling 241 are arranged in pairs on both sides of the worm. In this way, the substrate can move between the two rollers 24 arranged in pairs and can pass through the gap between the two rollers 24, thereby realizing linear continuous feeding, and can achieve full-scale flying without leaving edges, and can avoid wasting a section of the tail. The structure is simple and can protect the shape of the substrate 7 to avoid deformation of the substrate 7.

[0070] In addition, the feeding mechanism 2 can also adopt the feeding mechanism in the prior art to perform continuous feeding.

[0071] refer to Figure 4 The knurling 241 on a roller 24 is divided into multiple sections, and each section of the knurling is used to convey a different substrate 7. For example, the knurling 241 on a roller 24 is divided into four sections along the axial direction. In this way, the feeding mechanism 2 can convey four substrates to the clamping mechanism 3 and the wing mechanism 4 at a time, thereby improving the feeding efficiency.

[0072] The roller 24 is rotatably arranged. For example, the two ends of the roller 24 are provided with bearings, which are fixed on the housing, so that the roller 24 can be driven to rotate when the turbine 23 rotates.

[0073] The knurling is vertical and perpendicular to the direction of the substrate 7. For example, the knurling is a vertical bar, and the length direction of the vertical bar is parallel to the axial direction of the roller 24. The advantage of this is that the substrate 7 can be smoothly moved in a straight line, thereby improving the consistency of the product.

[0074] refer to Figure 5 and Figure 6The first clamping unit 3A1 and the second clamping unit 3B1 each include an elastic clamping unit 311, a clamping actuator 312, and a release actuator 313. The clamping actuator 312 and the release actuator 313 are both fixedly connected to the elastic clamping unit 311. The clamping actuator 312 contacts the second rotating push-up unit 3B2 so that the second clamping unit 3B1 can press the substrate 7; for example, the second clamping unit 3B1 is provided with a guide column, which is movably arranged in the shell, and the shell is stationary, so that the second clamping unit 3B1 can move back and forth on the shell; the second rotating push-up unit 3B2 includes an eccentric rotating shaft, so that the thick part of the second rotating push-up unit 3B2 presses against the clamping actuator 312, so that the second clamping unit 3B1 moves away from the shell and approaches the substrate 7, and the same is true for the first clamping unit 3A1, thereby pressing the substrate. The release actuator 313 contacts the second rotating lift unit 3B2, allowing the second clamping unit 3B1 to release the substrate 7. For example, the thin portion of the second rotating lift unit 3B2 presses against the release actuator 313, causing the second clamping unit 3B1 to move closer to the housing and away from the substrate 7. Similarly, the first clamping unit 3A1 is similarly moved, thereby releasing the substrate 7. The elastic pressing unit 311 can elastically contact the substrate 7. For example, the elastic pressing unit 311 is elastic, or the portion that contacts the substrate is elastic.

[0075] According to the above, the substrate 7 is located between the first clamping unit 3A1 and the second clamping unit 3B1, and is brought into contact with the clamping actuator 312 or the loosening actuator 313 by rotating the top opening unit, thereby realizing periodic clamping and loosening of the substrate 7, and an elastic clamping unit 311 is provided. In this way, the substrate 7 is clamped while avoiding deformation of the substrate 7, thereby facilitating continuous flying of the wing.

[0076] As mentioned above, the first rotating top opening unit 3A2 and the second rotating top opening unit 3B2 each include an eccentric rotating shaft, and the cross section of the eccentric rotating shaft is as follows: Figure 3 The first rotary lift unit 3A2 or the second rotary lift unit 3B2 comprises a uniform radius section 321 and an unequal radius section 322. The uniform radius section 321 and the unequal radius section 322 are connected. The uniform radius section 321 is the aforementioned thick portion. Thus, when the thick portion of the first rotary lift unit 3A2 or the second rotary lift unit 3B2 presses against the pressing actuator 312, the substrate 7 is kept pressed until the scraping is completed and then released. The unequal radius section 322 is the aforementioned thin portion.

[0077] In order to firmly clamp the substrate and prevent it from moving during scraping, the surfaces of the first clamping unit 3A1 and the second clamping unit 3B1 are both provided with concave and convex portions for contacting the surface of the substrate 7. For example, the concave and convex portions are teeth.

[0078] refer to Figure 6The clamping actuator 312 includes a clamping shaft 3121 and a clamping rotating member 3122. The clamping shaft 3121 is fixedly connected to the elastic clamping unit 311. The clamping rotating member 3122 is rotatably fixed to the clamping shaft 3121 and contacts the second rotating push-up unit 3B2. When the second rotating push-up unit 3B2 contacts the surface of the clamping rotating member 3122, the clamping rotating member 3122 is squeezed and rotates about the clamping shaft 3121, bringing the second clamping unit 3B1 closer to the substrate 7. This reduces friction between the components and thus reduces wear on the components. For example, the clamping rotating member 3122 is a bearing.

[0079] refer to Figure 6 The release actuator 313 includes a release shaft 3131 and a release rotating member 3132. The release shaft 3131 is fixedly connected to the elastic pressure unit 311. The release rotating member 3132 is rotatably fixed to the release shaft 3131 and contacts the second rotating lifting unit 3B2. When the second rotating lifting unit 3B2 contacts the surface of the release rotating member 3132, the release rotating member 3132 is squeezed and rotated about the release shaft 3131, moving the second clamping unit 3B1 away from the substrate. This reduces friction between the components and thus reduces wear. For example, the release rotating member 3132 is a bearing.

[0080] refer to Figure 7 The elastic pressing unit 311 includes an elastic pressure strip, a connecting pressure strip, a pressing main board and a spacing adjustment unit. For example, the material of the elastic pressure strip is spring steel. The elastic pressure strip is elastically connected to the pressing main board, and the connecting pressure strip is arranged between the elastic pressure strip and the pressing main board. The spacing adjustment unit is arranged on the pressing main board and can support the connecting pressure strip to change the distance between the elastic pressure strip and the pressing main board. In this way, by adjusting the spacing adjustment unit, the elastic pressure strip can be moved away from or close to the pressing main board. The elastic pressure strip is used to directly press the substrate 7, and the degree to which the first clamping unit 3A1 presses the substrate 7 can also be changed to adapt to substrates of different sizes.

[0081] The pressing shaft 3121 and the releasing shaft 3131 are both fixedly connected to the pressing main board.

[0082] The elastic connection between the elastic pressure strip and the pressing main board is as follows: the elastic pressure strip and the pressing main board are connected through an elastic connection unit. Figure 11 The elastic connection unit includes a connecting rod and an elastic member. In one example, the elastic member is a compression spring. One end of the connecting rod presses the elastic member against one side of the compression mainboard, while the other end of the connecting rod is fixedly connected to the connecting pressure strip. When adjusting the spacing adjustment unit, the connecting pressure strip drives the connecting rod, causing the elastic member to deform, thereby allowing the elastic pressure strip to move away from or closer to the compression mainboard.

[0083] In order to more reliably press the substrate 7, the two ends of the side of the elastic pressure strip that contacts the substrate 7 are provided with concave and convex parts, which are teeth, and the maximum thickness of the middle part of the elastic pressure strip is smaller than the maximum thickness of the two ends, that is, the middle part of the elastic pressure strip is thin and the two ends are thick. In this way, the two ends of the elastic pressure strip can undergo elastic deformation after contacting the substrate 7 to prevent the substrate from being squeezed and causing deformation.

[0084] There are multiple elastic strips and connecting strips, and the number of these strips can be the same. The number of spacing adjustment units corresponds to the number of elastic strips. One elastic strip overlaps and secures one connecting strip. One elastic strip is used to compress one substrate 7, and one spacing adjustment unit is used to adjust the distance between one elastic strip and the main compression plate. This allows the compression force applied to each substrate 7 to be individually adjusted, ensuring that each substrate 7 is securely fixed and product consistency is guaranteed.

[0085] refer to Figure 11 The spacing adjustment unit includes an adjustment bolt, which is threadedly connected to and passes through the clamping main plate. One end of the adjustment bolt can support the connecting pressure strip. Loosening or tightening the adjustment bolt moves the elastic pressure strip away from or closer to the clamping main plate. Of course, an adjustment nut can also be provided between the adjustment bolt and the clamping main plate to lock the adjustment bolt. This prevents the adjustment bolt from loosening during the substrate clamping process after adjustment, thereby preventing the degree of substrate compression from changing.
