Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber processing devices, in particular to a glass fiber punching device. Background Art

[0002] Glass fiber has good insulation properties, so it can be used in the circuit board industry to insulate between layers of multi-layer circuit boards. For the glass fiber that has been cut to match the size of the circuit board, it is also necessary to punch holes at the corresponding positions on it to make room for matching with the circuit board.

[0003] In the existing glass fiber punching, generally after stacking multiple layers of glass fiber to a certain thickness, drilling equipment is used to punch holes. Although this punching method can be used for batch punching, there will be burrs at the holes of the glass fiber after punching, which affects the quality of the holes. In addition, after multi-layer punching, adjacent glass fibers will be entangled due to the interaction between the upper and lower holes. In addition, the hole-forming method of PCB boards or copper sheets on PCB boards can be used for reference, such as punching. For example, an automatic position-adjusting multi-camera alignment punching machine with application number 201821131020.2 uses punching to form holes with better quality. However, it is for punching hard materials, which is not suitable for the flexible material of glass fiber. In addition, the punch unit needs to be easy to fix and stably fix and also needs to be easy to adjust the position to be suitable for punching at different positions. Utility Model Content

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 4 As shown, a glass fiber punching device includes a machine table 10, a lower die 20, a support mechanism 30 and an upper die mechanism 50. A plurality of lower dies 20 are arranged on the machine table 10. The lower die 20 has a blanking hole position that matches the position where the glass fiber needs to be punched. The number of the lower dies 20 and the number or position of the blanking hole positions on the lower die 20 are set according to the number and position of the punching holes on the glass fiber. The support mechanism 30 is arranged on the machine table 10 for carrying the glass fiber, and the support mechanism 30 is provided with an opening 320 that penetrates its body and matches the lower die 20, which can be used for the punch to act on the glass fiber to flush the waste material through the opening 320 to the lower die 20. In the blanking hole of the mold 20, the upper mold mechanism 50 is arranged at the output end of the driving mechanism 40 located on the machine table 10. The upper mold mechanism 50 includes an upper mold plate 51, and a plurality of upper mold assemblies 52 arranged on the upper mold plate 51 and matching with the lower mold 20. The upper mold assembly 52 includes an upper mold fixing block 521, a lifting cylinder 522 and a punch unit 523. The upper mold fixing block 521 is arranged at the lower end of the upper mold plate 51, the lifting cylinder 522 is arranged on the upper mold plate 51 and a pressure block 524 is provided at the output end. The pressure block 524 is driven to abut against the punch unit 523 to fix the punch unit 523 in the upper mold fixing block 521.

[0033] In the present invention, since glass fiber is a relatively flexible material, the glass fiber is loaded onto the support mechanism 30 by manual or automated equipment for supporting the glass fiber. The glass fiber on the support mechanism 30 can be in the form of sheet glass fiber (one or more sheets stacked) or non-sheet glass fiber, that is, continuous glass fiber. The glass fiber is located on the support mechanism 30 to cover the opening 320, the lower mold 20, and the blanking hole on the lower mold 20. Then the driving mechanism drives the upper mold plate 51 to move downward, and the punch unit 523 in the upper mold assembly 52 acts on the glass fiber and cooperates with the lower mold 20 to punch holes in the glass fiber. The waste after punching is discharged through the blanking hole to complete the entire punching action. The carried flexible glass fiber can more easily complete the punching action. Since the punch unit 523 is fixed on the upper mold fixing block 521 by the pressing block 524 driven by the lifting cylinder 522, the fixing effect is more stable, and it is easier to adjust the horizontal position of the punch unit 523 after the lifting cylinder 522 drives the pressing block 524 to separate from the punch unit 523 to adapt to the adjustment of the punching position. The adjustment is also more convenient, and the adjustment of different punching positions of different batches of glass fibers and multiple punching positions on the same batch of glass fibers can be quickly realized, which has better applicability and convenience of adjustment.

[0034] Combination Figures 4 to 6 As shown, a slot 5230 is provided on at least one side wall of the punch unit 523, and the pressure block 524 is at least partially embedded in the slot 5230 and can be vertically moved at least relative to the slot 5230. Specifically, the pressure block 524 includes a main body connecting block 5241 and a side block 5242 arranged on the connecting block 5241. The connecting block 5241 is connected to the output end of the lifting cylinder 522 passing through the socket 5211 on the upper mold fixing block 521, and the side block 5242 is embedded in the slot 5230 and can be vertically moved relative to the slot 5230, so as to facilitate the operation of the slot 5230 of the punch unit 523 to translate relative to the side block 5242 to adjust the position of the punch unit 523, and the lifting cylinder 522 drives the side block 5242 to abut against the top wall of the slot 5230 to fix the punch unit 523 on the upper mold fixing block 521.

[0035] Preferably, a positioning groove 5210 may be provided on the upper die fixing block 521 , and the upper portion of the punch unit 523 is embedded in the positioning groove 5210 to achieve wrapping and positioning of the punch unit 523 , which may have more excellent installation stability.

[0036] Furthermore, the punch unit 523 includes a base plate 5231, a punch 5232 and a positioning pin 5233. The base plate 5231 is provided with a slot 5230. The punch 5232 is provided on the base plate 5231. The positioning pin 5233 is provided on the base plate 5231 so as to be liftable by means of an elastic member 5234, and its upper end protrudes from the base plate 5231. Specifically, the punch 5232 is provided on one side of the base plate 5231, and the positioning pin 5233 is provided on the other side of the base plate 5231, and has a middle cavity 523a on this side, and is provided with a side groove 523b connected to the middle cavity 523a. The positioning pin 5233 is provided in the middle cavity 523a, and its lower end abuts against the bottom wall of the middle cavity 523a through the elastic member 5234. The elastic member 5234 is selected from a spring having excellent elasticity, and abuts against the side wall of the positioning pin 5233. The fixedly connected handle 5235 extends out of the side groove 523b. The handle 5235 is moved downward to control the positioning pin 5233 to press down the spring to retract the upper end of the positioning pin 5233 into the middle cavity 523a. After the handle 5235 is released, the positioning pin 5233 extends upward and protrudes out of the base plate 5231 under the elastic restoring force of the spring. Therefore, a plurality of positioning holes (not shown) can be provided on the upper mold fixing block 521 (positioning groove 5210). The positioning pin 5233 is driven by the elastic member to extend into the positioning hole to position the punch unit 523 on the upper mold fixing block 521. The positions of the plurality of positioning holes are set according to the positions of the holes required to be punched on the glass fiber. Simultaneously, a plurality of corresponding blanking holes are also set on the lower mold 20. The cooperation between the positioning pin 5233 and the positioning hole can ensure the adjustability and accuracy of the punching position.

[0037] In addition, a gasket 5236 can be wrapped around the outside of the lower end of the punch 5232. On the one hand, the compressibility of the gasket 5236 does not affect the normal punching action of the end of the punch 5232. On the other hand, it can prevent the side of the lower end of the punch 5232 from making hard contact with the flexible glass fiber to cause damage to the glass fiber material, thereby ensuring the quality of glass fiber processing.

[0038] For example Figure 2 As shown, the support mechanism 30 includes a pen-shaped cylinder 31 and a support plate 32. A plurality of pen-shaped cylinders 31 are arranged on the machine 10, and a support plate 32 is arranged at the output end. The support plate 32 is located above the lower mold 20, and the opening 320 is formed on the support plate 32, so that the support plate 32 can carry the glass fiber and link with the upper mold mechanism 50 during the punching action; the support plate 32 is provided with a guide column 33 which can move vertically in the machine 10, so as to ensure the accuracy of the vertical movement of the support plate 32.

[0039] like Figure 7 and Figure 8As shown, the glass fiber punching device also includes a pressing mechanism 60, which includes a lifting assembly 61 and a lower pressing plate 62. A pair of lifting assemblies 61 are arranged on the machine 10, and a lower pressing plate 62 is provided at the output end thereof. The lower pressing plate 62 is arranged below the punch unit 523, and is provided with a through hole 620 matching the punch unit 523. When the glass fiber is carried on the support mechanism 30 (support plate 32), its flexible texture easily causes it to be misaligned when being punched, which in turn causes the punching to fail to be completed, or the punching position is inaccurate due to the misalignment. Therefore, the lifting assembly 61 is used to drive the lower pressing plate 62 to press the glass fiber onto the support mechanism 30, and then the punch unit 523 is used to punch to ensure the accuracy and stability of the punching.

[0040] More specifically, the lifting assembly 61 includes a fixed frame 611, a drive unit 612 (linear electric cylinder), a lifting plate 613 and a guide rod 614. The fixed frame 611 is arranged on the machine platform 10, the drive unit 612 is arranged on the fixed frame 611, and a lifting plate 613 is provided at the output end. A plurality of guide rods 614 are arranged at the upper end of the lifting rod 613 and pass upward through the machine platform 10. The lower pressure plate 62 is arranged at the upper end of the guide rod 614, thereby ensuring the stability and accuracy of the overall lifting of the lower pressure plate 62.

[0041] For example Figure 1 As shown, the driving mechanism 40 includes a frame 41, a hydraulic cylinder 42 and a rebound assembly 43. The frame 41 is arranged on the machine platform 10. The hydraulic cylinder 42 includes a main cylinder and auxiliary cylinders located at the four corners of the frame 41, and the output ends are connected to the upper mold mechanism 50, so that the punching force of multiple punch units 523 located on the upper mold plate 51 can be the same. A rebound assembly 43 is arranged between the upper mold mechanism 50 and the machine platform 10; in addition, a plurality of guide columns 44 vertically passing through the upper mold plate are provided on the machine platform 10 to ensure the accuracy of the vertical movement of the upper mold mechanism 50.

[0042] The glass fiber punching device also includes a waste collection mechanism 70, which includes a funnel-shaped collection box 71. The collection box 71 can be connected to an external vacuum device. It is arranged at the lower end of the machine table 10 and is connected to the unloading hole of the lower mold 20. It is used to quickly collect the waste generated by the glass fiber punching. At the same time, it can also collect dust generated during the punching process to improve the working environment.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
