Description

Technical Field

[0001] This utility model relates to the field of embossing equipment, specifically a embossing device for thin plates. Background Technology

[0002] During the manufacturing process of circuit boards, photosensitive additives are applied to the upper and lower surfaces of the copper-clad laminate, and a release film is applied to the outer layer of the photosensitive additives. The release film needs to be removed before the developing process. However, since a dry film process is required before developing—that is, attaching the dry film to the copper-clad laminate—hot pressing is used to soften the photosensitive additives. However, this softening can cause the photosensitive additives to leak from the edges and coat the edges of the release film, making it impossible to peel off. Therefore, the release film needs to be textured. Existing textured devices use a textured mechanism on the conveyor to texture the release film suspended after being conveyed. This type of device is only suitable for circuit boards thicker than 0.1mm that are not easily deformed; in the industry, boards thicker than 0.1mm are considered thick boards. Circuit boards with a thickness of less than 0.1mm are classified as thin boards. When the thickness of a circuit board is less than 0.1mm, it will bend and deform after being suspended in the air, which makes it impossible to ensure that the existing rubbing device can be used to rub the board normally.

[0003] Therefore, it is necessary to provide a special knitting device for thin plates. Summary of the Invention

[0004] This utility model provides a special rubbing device for thin plates, which effectively solves the problem that existing rubbing devices cannot perform normal rubbing on thin plates.

[0005] The technical solution adopted in this utility model is:

[0006] A special rubbing device for thin plates includes a roller feeding mechanism, a pressing and rubbing mechanism disposed at the end of the roller feeding mechanism, and a clamping mechanism. The pressing and rubbing mechanism is located between the clamping mechanism and the roller feeding mechanism.

[0011] Furthermore, the upper knitting component includes a sliding frame slidably connected to the upper guide rail, a No. 6 cylinder and a No. 8 cylinder vertically arranged on the sliding frame, an upper knitting wheel assembly arranged at the output end of the No. 6 cylinder, and an upper sticking wheel assembly arranged at the output end of the No. 8 cylinder.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the thin plate special knitting device provided in the embodiment of this application includes a roller feeding mechanism 1, a pressing knitting mechanism 2 disposed at the end of the roller feeding mechanism 1, and a clamping mechanism 3, wherein the pressing knitting mechanism 2 is located between the clamping mechanism 3 and the roller feeding mechanism 1. Figure 2 As shown, the clamping mechanism 3 includes a fixed plate 31 spaced apart at one end of the pressing and knitting mechanism 2, a first guide rail 32 vertically arranged on the fixed plate 31, a lifting seat 33 slidably arranged on the first guide rail 32, a first cylinder 34 fixedly arranged on the fixed plate 31 for driving the lifting seat 33 to rise and fall, a second guide rail 35 arranged along the X-axis on the lifting seat 33, a sliding seat 36 slidably arranged on the second guide rail 35, a horizontal drive assembly 37 arranged on the lifting frame 42 for driving the sliding seat 36 to slide along the second guide rail 35, and a plurality of clamping cylinders 38 arranged along the Y direction on the side of the sliding seat 36 opposite to the pressing and knitting mechanism 2. The clamping cylinder 38 includes a cylinder body 381 fixedly arranged on the sliding seat 36 and two clamping blocks 382 arranged on the cylinder body 381 that open and close vertically.

[0024] In actual use, the thin plate moves along the roller conveyor 1 toward the pressing and knitting mechanism 2. The first cylinder 34 drives the lifting seat 33 to rise and fall, and the clamping cylinder 38 opens. After the front end of the thin plate passes between the pressing and knitting mechanism 2 and the two clamping blocks 382 of the clamping cylinder 38, the cylinder body 381 drives the two clamping blocks 382 to close and clamp the front end of the thin plate. Then the pressing and knitting mechanism 2 presses the rear end of the thin plate and knits it. After the knitting is completed, the pressing mechanism resets, the two clamping blocks 382 open, and the horizontal drive component 37 drives the sliding seat 36 to move away from the thin plate so that the sliding seat 36 and the front end of the thin plate are not on the same vertical plane. Then the first cylinder 34 drives the lifting seat 33 to move down so that the sliding seat 36 avoids the subsequent movement of the thin plate.

[0025] In the above design, the front end of the thin plate can be clamped by the clamping mechanism 3, and the thin plate surface can be fixed in conjunction with the pressing and knitting mechanism 2. This prevents the thin plate from bending downwards after the front end of the thin plate detaches from the roller feeding mechanism 1 due to its own strength, thus improving the accuracy and efficiency of knitting.

[0026] Specifically: such as Figure 2 As shown, the clamping mechanism 3 also includes a plurality of pulleys 39 arranged along the Y-axis on the upper surface of the sliding seat 36, with the Y-axis as the axis of rotation.

[0027] In actual use, after the knitting is completed, the lifting seat 33 moves down to the upper edge of the pulley 39 so that it can contact the lower end face of the thin plate, so that the thin plate is supported by the pulley 39 during subsequent conveying.

[0028] In the above design, the structure of the clamping mechanism 3 can assist in conveying the thin plate after the embossing process.

[0029] Specifically: such as Figure 3 As shown, the pressing and knitting mechanism 2 includes a mounting plate 21 disposed at the end of the roller conveying mechanism 1 and having an outlet 201, a pressing component 22 disposed on the mounting plate 21 for pressing the upper and lower ends of the thin plate, and a knitting component 23 for knitting the thin plate.

[0030] In actual use, the thin plate is conveyed along the roller conveyor 1 through the plate outlet 201 and enters the rubbing working area. Then, the pressing component 22 presses the rear end of the thin plate, the clamping mechanism 3 clamps the front end of the thin plate, and then the rubbing component 23 rubs the thin plate.

[0031] In the above design, the structural design and specific implementation of the pressing and knitting mechanism 2 can effectively achieve the positioning and knitting of the thin plate.

[0032] Specifically: such as Figure 2As shown, the clamping assembly 22 includes an upper clamping plate 221 and a lower clamping plate 222 symmetrical about the outlet 201, a third cylinder 223 mounted on the mounting plate 21 for driving the upper clamping plate 221 to rise and fall, and a fourth cylinder 224 mounted on the mounting plate 21 for driving the lower clamping plate 222 to rise and fall. The third cylinder 223 and the fourth cylinder 224 are symmetrical about the outlet 201.

[0033] In actual use, after the thin plate passes through the outlet 201 and enters the rubbing operation area, cylinder 223 drives the upper clamping plate 221 to move downward, and cylinder 224 drives the lower clamping plate 222 to move upward, so that the upper clamping plate 221 and the lower clamping plate 222 clamp the upper and lower end faces of the rear end of the thin plate. After the rubbing is completed, cylinder 223 drives the upper clamping plate 221 to reset, and cylinder 224 drives the lower clamping plate 222 to reset.

[0034] In the above design, the clamping component 22 can quickly clamp the rear end of the thin plate.

[0035] Specifically: such as Figure 3 and Figure 4 As shown, the embossing assembly 23 includes an upper guide rail 231 and a lower guide rail 232 disposed on the upper end of the mounting plate 21, an upper end face embossing component 233 slidably disposed on the upper guide rail 231, a lower end face embossing component 234 slidably disposed on the lower guide rail 232, and a driving component 235 disposed on the mounting plate 21 for synchronously driving the upper end face embossing component 233 and the lower end face embossing component 234 to move horizontally. The upper end face embossing component 233 and the lower end face embossing component 234 are symmetrical along the outlet 201.

[0036] In actual use, the upper end face rubbing component 233 and the lower end face rubbing component 234 are synchronously driven by the driving component 235 to slide along the upper guide rail 231 and the lower guide rail 232 respectively, so that the upper end face rubbing component 233 and the lower end face rubbing component 234 rub the release film on the upper end face and the lower end face of the thin plate along a predetermined path respectively.

[0037] In the above design, the structural design and specific implementation of the knurling component 23 can effectively achieve simultaneous knurling of the upper and lower surfaces of the thin plate, effectively preventing the thin plate from warping due to knurling.

[0038] Specifically: such as Figure 5 As shown, the upper knitting component 233 includes a sliding frame 2331 slidably connected to the upper guide rail 231, a sixth cylinder 2332 and an eighth cylinder 2335 vertically arranged on the sliding frame 2331, an upper knitting wheel assembly 2333 arranged at the output end of the sixth cylinder 2332, and an upper sticking wheel assembly 2334 arranged at the output end of the eighth cylinder 2335. The upper knitting wheel assembly 2333 and the upper sticking wheel assembly 2334 are arranged along the Y-axis direction.

[0039] In actual use, the sliding frame 2331 is driven by the drive component 235 to slide along the upper guide rail 231. The sixth cylinder 2332 and the eighth cylinder 2335 respectively drive the upper rubbing wheel assembly 2333 and the upper adhesive wheel assembly 2334 to descend to the working height. The drive component 235 drives the upper rubbing component 233 to slide along the upper guide rail 231, so that the upper rubbing wheel assembly 2333 rubs the upper surface of the thin plate, and the upper adhesive wheel assembly 2334 adheres and peels off the release film after rubbing.

[0040] In the above design, the structural design and specific implementation of the upper embossing component 233 can effectively peel off the release film after embossing.

[0041] Specifically: such as Figure 3 and Figure 4 As shown, the driving component 235 includes a driven wheel A3501 and a driven wheel B3502 mounted on the mounting plate 21, a first rotating shaft 3503, a second rotating shaft 3504, a driven wheel a3505 mounted at one end of the first rotating shaft 3503, a driven wheel b3506 mounted at one end of the second rotating shaft 3504, an upper synchronous belt 3507 wound around driven wheels A3501 and a3505, a lower synchronous belt 3508 wound around driven wheels B3502 and b3506, a drive shaft 3509 mounted on the mounting plate 21, a drive wheel 3510 coaxially mounted on the drive shaft 3509, and a fixed... The mounting plate 21 includes a motor 3511 for driving the drive shaft 3509, a driven wheel C3512 at the other end of the first shaft 3503, a driven wheel D3513 at the other end of the second shaft 3504, a drive synchronous belt 3515, and several tensioning wheels 3514. The drive wheel 3510, driven wheel C3512, and driven wheel D3513 are driven by the drive synchronous belt 3515. The tensioning wheels 3514 are used to tension the drive synchronous belt 3515. The upper synchronous belt 3507 is connected to the upper end face knitting part 233, and the lower synchronous belt 3508 is connected to the lower end face knitting part 234.

[0042] In actual use, the motor 3511 drives the drive shaft 3509 to rotate, which in turn drives the drive wheel 3510 to rotate synchronously. The drive synchronous belt 3515 drives the driven wheels C3512 and D3513 to rotate synchronously, thereby achieving synchronous rotation of the first rotating shaft 3503 and the second rotating shaft 3504. This drives the driven wheels a3505 and b3506 to rotate synchronously. With the cooperation of driven wheels A3501 and a3505, the first synchronous belt drive is realized. With the cooperation of driven wheels B3502 and b3506, the lower synchronous belt 3508 drive is realized. Thus, the first synchronous belt drives the upper knurling part 233 to slide along the upper guide rail 231, and the lower synchronous belt 3508 drives the lower knurling part 234 to slide along the lower guide rail 232.

[0043] In the above design, the structural design and specific implementation of the driving component 235 can effectively achieve synchronous and stable driving of the upper embossing component 233 and the lower embossing component 234.

[0044] Specifically: such as Figure 1 and Figure 6 As shown, a transition conveying mechanism 4 is also provided between the pressing and knitting mechanism 2 and the clamping mechanism 3. The transition conveying mechanism 4 includes a base 41, a lifting frame 42 set on the base 41, a No. 7 cylinder 43 set on the base 41 for driving the lifting frame 42 to rise and fall, a No. 1 rotating shaft 44 rotatably set on the upper end face of the lifting seat 33 with the Y-axis as the axis, and wheel pieces 45 arranged along the Y-axis and coaxially fixedly connected to the No. 1 rotating shaft 44.

[0045] In actual use, when the thin plate is being rubbed, cylinder 43 drives the lifting frame 42 to not contact the thin plate. After the rubbing of the thin plate is completed, cylinder 43 drives the lifting frame 42 to rise, and with the cooperation of the rotating shaft 44, the wheel 45 is rolled and connected to the lower end face of the thin plate.

[0046] In the above design, the structural design and specific implementation of the transition conveying mechanism 4 can support the thin plate, prevent the thin plate from bending due to the gap between the pressing and knitting mechanism 2 and the clamping mechanism 3, and ensure the smooth subsequent conveying of the thin plate.

[0047] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
