[0056] In the utility model, a multi-stage cylinder assembly 4 and a single-stage cylinder 5 are sequentially installed on the upper mounting surface 2 and the lower mounting surface 3 of the template 1. The multi-stage cylinder assembly 4 is arranged on the XY axis of the template 1, and the single-stage cylinder 5 is arranged at the four corners.

[0057] Example 2

[0058] like Figures 1 to 9 The punching device with a freely combinable mode shown in the figure includes a template 1, which can be driven by a cylinder or a motor to move up and down, and is used to meet the punching requirements of the inner circuit board and other electronic components; the template 1 is essentially an auxiliary plate with a certain thickness, with a certain number and position of punching holes, and cooperates with the punching needle 71 at the corresponding position to complete the opening of the inner circuit board, and the upper and lower sides of the template 1 are respectively provided with an upper mounting surface 2 and a lower mounting surface 3, that is, the top surface and the bottom surface, for mounting various components. A multi-stage cylinder assembly 4 is provided on the top of the upper mounting surface 2, and single-stage cylinders 5 are symmetrically provided on the front and rear sides of the lower mounting surface 3. A corresponding number of stamping structures 6 are connected to the multi-stage cylinder assembly 4 and the multiple output ends of the single-stage cylinder 5, that is, the stamping structure 6, the single-stage cylinder 5 and the multi-stage cylinder assembly 4 can all move up and down with the template 1, and the single-stage cylinder 5 and the multi-stage cylinder assembly 4 can also drive the stamping structure 6 to move, and cooperate with the opening of the inner circuit board.

[0059] A punching needle structure 7 is provided on the side of the punching structure 6 on the template 1. The punching needle structure 7 has a plurality of punching needles 71 and is arranged at a preset distance. The "preset distance" can be set or adjusted according to the required distance and number of punching holes. When the template 1 is pressed down, the output end of the punching structure 6 will press against the punching needle 71 to complete the downward punching action.

[0060] Next, the punching structure also includes a bracket, a top column and a spring. A plurality of brackets are provided at the bottom of the lower mounting surface 3, and a specified number of punch pins 71 are installed on the bracket, which can be one row, two rows or more; specifically, the head of the punch pin 71 is supported on the bracket, one end of the spring passes through the support plate and rests against the head, and the other end rests against the pressure plate below. The upper end of the top column passes through the template 1 and protrudes from the upper mounting surface 2, and the lower end rests against the head of the punch pin 71. Then, when the stamping structure 6 moves downward, the stamping structure 6 operates to rest against the upper end of the top column, thereby driving the punch pin 71 to complete a downward pressing action.

[0061] Example 3

[0062] like Figures 1 to 9 The punching device shown in the figure can be freely combined. The single-stage cylinder 5 and the multi-stage cylinder assembly 4 can drive the punching structure 6 to move on the template 1, and then drive the punching structure 6 to resist the top pillars at different positions in the punching needle structure 7, so as to press down the punching needles 71 at different positions, and then there is no need to replace the molds at different hole positions, thereby reducing the time cost of punching and improving its punching efficiency. Furthermore, the four output ends of the multi-stage cylinder assembly 4 are all connected with a connecting plate 8, and the punching structure 6 is installed on the connecting plate 8. Through the drive of the multi-stage cylinder assembly 4, the punching structure 6 can be driven to move through the mounting plate to align with the punching holes at different positions, so as to meet the punching requirements of the inner layer circuit board with multiple holes.

[0063] The stamping structure 6 can be divided into a pressure cylinder 601, a first pressure block 602, a second pressure block 603 and a pin head 604. The pressure cylinder 601 is installed on the connecting plate 8. At the same time, any component between the first pressure block 602 and the pin head 604 will be installed on the output shaft of the pressure cylinder 601, and then the pressure cylinder 601 will drive the first pressure block 602 and the pin head 604 to move until they are placed above the required punching needle 71 or staggered from the punching needle 71; correspondingly, the second pressure block 603 is installed on the output shaft of the single-stage cylinder 5, and then the single-stage cylinder 5 will drive the second pressure block 603 to move until it is placed above the required punching needle 71 or staggered from the punching needle 71.

[0064] A plurality of blocking frames 10 are provided on the top of the upper mounting surface 2, and the blocking frames 10 are all located above the punching pins 71, and guide holes 11 corresponding to the number and positions of the punching pins 71 are opened on the blocking frames 10; when the multi-stage cylinder assembly 4 drives the upper stamping structure 6 to operate, the corresponding first pressing block 602 and the ejector pin head 604 are moved, and the required punching pin 71 is selected. Since the first pressing block 602 and the ejector pin head 604 are both blocked by the blocking frame 10, the punching pin 71 selected by the first pressing block 602 and the ejector pin head 604 can be pressed toward the inner layer circuit board during the downward movement of the template 1 to complete the punching; at the same time, the remaining punching pins 71 are squeezed upward through the guide holes 11 to avoid excessive force causing spring overload and damage to elasticity. Similarly, the second pressure block 603 driven by the single-stage cylinder 5 will be located between the bottom of the template 1 and the punch needle 71. When the inner-layer circuit board is placed under the template 1, the downward movement of the template 1 will drive the second pressure block 603 to move downward as well. When the single-stage cylinder 5 drives the second pressure block 603 to rest between the bottom of the template 1 and the punch needle 71, it can indirectly press the punch needle 71 to punch the circuit board. Conversely, when the second pressure block 603 is withdrawn from between the bottom of the template 1 and the punch needle 71, the corresponding punch needle 71 will move upward under the extrusion force and will not punch.

[0065] Example 4

[0066] In the multi-stage cylinder assembly 4 in the present application, the maximum stroke of the output shaft of each driving cylinder is the same or different, and the number of driving cylinders depends on the number of punch pins 71 and the arrangement distance between multiple punch pins 71, including at least 2, or 3, 4, 5, etc., which can be driven by multiple cylinders in a superimposed manner or by a single cylinder; for example, when the number of punch pins 71 is 4 and the distance between each punch pin 71 is 1.5 cm, 3 driving cylinders with a stroke of 1.5 cm can be set for driving, and the initial position of the stamping structure 6 will be located next to the first punch pin 71, and when the read information is that the second punch pin 71 is working, one of the driving cylinders is activated, driving the stamping structure 6 to move a distance of 1.5 cm to the side of the second punch pin 71; when the read information is that the third punch pin 71 is working, two of the driving cylinders are activated, driving the stamping structure 6 to move 3.0 cm to the side of the third punch pin 71, and so on.

[0067] Example 5

[0068] like Figures 1 to 9 A punching device with a freely combinable mode is shown, and the punching needle structure 7 in the present application is arranged with at least one group of punching needles 71, which can be one group, two groups, or more groups. In the present embodiment, the "group" is limited to an arrangement method of 2 rows, and one row can be 4 or 3 needles. The punching needle structure 7 is temporarily divided into 5 groups, namely, punching needle group A, punching needle group B, punching needle group C and punching needle group D, and then combined and installed according to the punching hole positions.

[0069] With the punch needle group A as the fixed point, the punch needle group A is installed at the center position of the four sides of the lower mounting surface 3, that is, one group is arranged on one side; the punch needle group A, the punch needle group B and the punch needle group C are arranged at a horizontal spacing, and the punch needle group B will be symmetrically arranged on the left and right sides of the punch needle group A with the punch needle group A as the center point, and the three groups of punch needles 71 all correspond to the selected punch needle 71 position of the three-stage driving cylinder 403; and the vertical spacing is set for the punch needle group A and the punch needle group D. Similarly, the punch needle group D will be symmetrically arranged on the front and back sides of the punch needle group A with the punch needle group A as the center point, and the three groups of punch needles 71 all correspond to the selected punch needle 71 position of the two-stage driving cylinder 402. That is, the tertiary driving cylinder 403 will drive the upper punching structure 6 to move and select the horizontal punching position, while the secondary driving cylinder 402 will drive the upper punching structure 6 to move and select the vertical punching position. After selection, the corresponding punching structure 6 will resist the punching needle 71, so that when the template 1 is pressed downward, the punching needle 71 can also punch the corresponding position of the inner circuit board.

[0070] It can be concluded that the number of pressure cylinders 601 in the punching structure 6 must be at least 3 to drive enough first pressure blocks 602 and ejector pins 604 to resist the punch pins 71 and punch the inner circuit board. And because the punch pin group A is in the center position, the pressure cylinder 601 driving the punch pin group A does not need to be changed accordingly, and only needs to follow the movement of the connecting plate 8 to select the corresponding punch pin 71 position.

[0071] In order to further increase the multiple possibilities of punching position combinations, the punching needle group C is also set as a horizontal punching position selection, so that it is symmetrically arranged on the front and rear sides of the lower mounting surface 3, corresponding to the selected punching needle 71 position of the single-stage cylinder 5; that is, the single-stage cylinder 5 will drive the upper stamping structure 6 to move, select or stagger the corresponding punching position, and only the selected punching needle 71 can punch the inner layer circuit board, and no hole will be punched if it is not selected.

[0072] Example 6

[0073] As can be seen from Example 3, the corresponding number of driving cylinders can be "the number of punching needles 71-1", that is, the number of intervals of the punching needles 71. Since the number of a row of punching needles 71 is at most 4 or 3, in this embodiment, the multi-stage cylinder assembly 4 is divided into a primary driving cylinder 401, a secondary driving cylinder 402 and a tertiary driving cylinder 403 for superimposed use. The driving punching structure 6 can accurately reach the side of each punching needle 71 to complete the punching action. The specific installation layout is as follows:

[0074] The front and rear sides of the upper mounting surface 2 are driven by three cylinders in a superimposed manner, and the first-stage driving cylinder 401 is fixedly installed on the inner side and then extends outward, so that the output shaft of the first-stage driving cylinder 401 is connected to the third-stage driving cylinder 403 through the second-stage driving cylinder 402, that is, the output shafts of the two third-stage driving cylinders 403 are connected to the connecting plate 8; the left and right sides of the upper mounting surface 2 are driven by two cylinders in a superimposed manner, and the first-stage driving cylinder 401 is fixedly installed on the outer side and then extends inward, so that the output shaft of the first-stage driving cylinder 401 is connected to the second-stage driving cylinder 402, and the two second-stage driving cylinders 402 are also connected to the connecting plate 8; it can be concluded that there are four connecting plates 8 located at the top of the upper mounting surface 2, that is, there are also four corresponding slide rails 91 and sliders 92, so that the connecting plate 8 and the stamping structure 6 components above it can all move stably.

[0075] In this embodiment, a multi-stage cylinder joint drive structure is used to replace the traditional motor and screw drive structure. At the same time, compared with the motor and screw drive structure, the multi-stage cylinder assembly 4 has a lower cost and a much better response speed than the motor, so that the stamping structure 6 can quickly reach the corresponding punch needle 71 position, thereby improving punching and production efficiency.

[0076] Example 7

[0077] In the process of punching holes in the inner layer circuit board, it is necessary to consider the different types and shapes of related tool holes required for the subsequent process, including but not limited to positioning holes, rivet holes or pin holes, etc. For example, common shapes of positioning holes are round, square, needle-shaped, linear, etc. In order to minimize the replacement frequency of the punch needle 71, the present embodiment further refines the punch needle group A into the punch needle group A1 and the punch needle group A2, and sets the shape of the punch needle 71 of the punch needle group A1 to a square hole, and the punch needle group A2 to a round hole, so that there is no need to frequently replace the punch needles 71 of different shapes, thereby improving efficiency. When punching, the operator can select the punch needle group A1 or the punch needle group A2 separately to realize the quick selection of the punch needles 71 of different shapes without replacement; the operator can also select the punch needle group A1 and the punch needle group A2 to punch holes at the same time to improve the selection of the type of the punch needle 71.

[0078] Then, there is one more set of options for the horizontal and vertical punching positions, and the punching options on the connecting plate 8 have become four sets. The fourth embodiment of "the number of pressure cylinders 601 in the punching structure 6 must be at least three to drive enough first pressure blocks 602 and ejector pins 604 to resist the punch pins 71 to punch the inner circuit board" is no longer feasible; and in order to minimize the installation cost, the present embodiment continues to limit the number of pressure cylinders 601 to 3, and in "and because the punch pin group A is in the center position, the driving of the punch pin group A does not need to be changed accordingly, just follow the connection The plate 8 can be moved to select the corresponding position of the punching needle 71". It is concluded that the punching needle group A is still in the center position, and the punching needle group A1 and the punching needle group A2 after being divided into two are also in a centrally symmetrical arrangement. Therefore, a sliding hole 12 is opened on the connecting plate 8, so that the output shaft movement range of the pressure cylinder 601 driving the punching needle group A is moderately located between the punching needle group A1 and the punching needle group A2, and then the first pressure block 602 connected to the pressure cylinder 601 will move left and right in the sliding hole 12, and the corresponding punching needle 71 position of the punching needle group A1 and the punching needle group A2 will be continuously selected.

[0079] Example 8

[0080] like Figures 1 to 9 A punching device with a freely combinable mode is shown, which is further provided with a visual positioning mechanism, which includes a mounting groove 13, a bracket 14 and a visual inspection camera 15. The four sides of the top of the template 1 are provided with mounting grooves 13, and the mounting groove 13 is a through groove. A visual inspection camera 15 is installed in the mounting groove 13 through the bracket 14. The visual inspection camera 15 takes pictures and inspects the circuit board from the mounting groove 13, and accurately positions the punched product, which further ensures the accuracy of the punching. Together with the position selection of the above-mentioned punching needle 71, it can quickly position and punch products of different sizes.

[0081] It should be noted that the visual inspection camera 15 can take pictures of the circuit board to be punched, complete image acquisition, and then convert the acquired image into a digital format and transmit it to the computer memory; after the processor processes the image, it quantifies the key features of the image, such as the size of the circuit board and the type and shape of the holes to be punched, and transmits these data to the control program, issues corresponding instructions, and quickly selects the corresponding punching positions of different combinations, which is convenient and quick, and greatly improves the punching efficiency.

[0082] In summary, the template 1 of the present invention has 5 rows of punching holes in the horizontal direction, namely C, B, A1, A2, B, C in sequence; and 4 rows of punching holes in the vertical direction, namely D, A1, A2, D in sequence;

[0083] Therefore, the above punching holes can be punched in combination according to different needs, and the combination can be single, double, triple or even more. For example:

[0084] 1. A1 or A2

[0085] 2.A (i.e. A1 and A2)

[0086] 3.A+B

[0087] 4.A+B+D

[0088] 5.A+B+C

[0089] 6. Combination molds such as A+B+C+D.
