[0021] In order to facilitate the understanding of the utility model, the utility model is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0023] See also Figure 1 and Figure 2The processing device 1000 includes a power device 1, a stamping assembly 2, a support assembly 3 and a processing table 4. The stamping assembly 2 includes a plurality of punches 21; the plurality of punches 21 are evenly distributed according to preset positions, and the power device 1 is connected to the plurality of punches 21 to provide power for the stamping assembly 2, so that the stamping assembly 2 moves in a desired direction, and the stamping function can be realized accordingly; the support assembly 3 includes a plurality of support members 31, and the support members 31 are provided with grooves (not marked). The plurality of support members 31 are used to abut and support the workpiece a to be processed, and one groove corresponds to one punch 21. The groove is used to accommodate the punch 21 when the punch 21 completes punching the workpiece a to be processed. The processing table 4 is used to hold the support assembly 3. The processing table 4 should ensure a certain degree of flatness to avoid the impact of the accuracy of the stamping assembly 2 when punching the workpiece to be processed due to the inclination of the platform when the processing device 1000 performs a stamping operation. The punch 21 squeezes the workpiece a, and the support member 31 provides support for the workpiece a. The interaction between the two forms a shearing effect on the workpiece a, thereby achieving a punching operation on the workpiece a.

[0024] It is worth noting that the workpiece a to be processed includes but is not limited to LCP plates, metal plates and composite materials plates. In the present embodiment, preferably, the workpiece a to be processed is an LCP plate, and the LCP plate is preset with a plurality of blind holes, and the number of layers of the LCP plate is any one of 4 to 15 layers.

[0025] For the punch 21 above, see Figure 3 The punch 21 includes a connecting piece 211 and an impact piece 212 connected to each other. One end of the impact piece 212 is fixed to the connecting piece 211, and the other end of the impact piece 212 is used to punch the workpiece a when the punch 21 is punching. The connecting piece 211 and the impact piece 212 are perpendicular to each other, and the connecting piece 211 is connected to the power device 1.

[0026] It is worth noting that the cross-section of the impact piece 212 includes but is not limited to circular, square, polygonal and irregular shapes, so that the hole punched out by the impact piece 212 is of the desired shape. Specifically in the present embodiment, the desired hole shape is circular, so preferably, the cross-section of the impact piece 212 is circular.

[0027] In some embodiments, a buffer pad (not shown) is provided at one end of the connecting member 211 close to the workpiece a to be processed, which is used to provide buffer protection for the workpiece a to be processed when the stamping assembly 2 stamps the workpiece a to be processed, thereby avoiding damage to the surface of the workpiece a.

[0028] It can be understood that the punch 21 can be fixed to the power device 1 by plugging it through the connecting piece 211. The power device 1 is correspondingly provided with multiple slide grooves (not marked) and several limiting parts (not shown in the figure). The slide groove is used to accommodate multiple punches 21 according to a preset layout, and the distance between any two adjacent slide grooves can be adjusted as needed. The several limiting parts are used to limit the multiple punches 21 in the same slide groove to prevent the multiple punches 21 from shaking in the slide groove, causing confusion in the preset layout.

[0029] It is worth noting that this preset layout is set according to the holes required for the workpiece a to be processed. Therefore, the distance between any two adjacent slides needs to be adjusted in combination with the required hole layout of the workpiece a to be processed, and the size of the limit portion also needs to be adjusted according to the required hole layout of the workpiece a to be processed, so that the distance between two adjacent punches 21 in the same slide can be changed as needed, thereby improving the applicability of the stamping assembly 2 and avoiding the need to re-open the mold of the stamping assembly 2 due to changes in the layout of the processing holes required for the workpiece a to be processed, resulting in an increase in the cost of the processing device 1000.

[0030] For the above-mentioned support member 31, please refer to Figure 3 The bottom wall of the groove of the support member 31 is provided with a through hole (not shown), which is used to discharge the waste formed by shearing after punching.

[0031] It can be understood that the diameter of the through hole is slightly larger than or equal to the diameter of the waste material to ensure that the waste material can be discharged smoothly through the through hole. In this embodiment, preferably, the diameter of the through hole is the same as the diameter of the groove.

[0032] Specifically, when the impact piece 212 punches the workpiece a, the waste material is cut and falls into the groove of the support piece 31, and the impact piece 212 also uses its own length to push the waste material out of the support piece 31 from the through hole while punching, so as to ensure the normal punching of the next time.

[0033] It can be understood that in order to collect waste, a collection trough (not shown) can also be set at the bottom of the support assembly 3. The collection trough can be set in the processing table 1, or set at the bottom of the processing table 1 and a connecting hole can be set in the processing table 1, so that the waste is discharged from the support member 31 and falls into the collection trough through the connecting hole.

[0034] In some embodiments, the cross-sectional area of ​​the groove gradually increases from the top of the support member 31 to the bottom of the support member 31, so that the groove presents a narrow top and wide bottom structure from the top of the support member 31 to the bottom of the support member 31, so that the resistance of the waste to the side wall gradually decreases during the process of being pushed by the impact member 212, thereby improving the discharge efficiency of the waste.

[0035] It is worth noting that the diameter of the through hole should be less than or equal to the diameter of the groove, and the diameter of the through hole should also be greater than or equal to the diameter of the waste. As long as the diameter of the through hole is within this range, the specific size of the through hole will not be illustrated one by one in this embodiment.

[0036] In some embodiments, see Figure 3 and Figure 4 , the length of the impact piece 212 is greater than or equal to 10mm; the length range of the impact piece 212 is sufficient to meet the punching processing depth of the existing LCP board, thereby ensuring the applicability of the processing device 1000 and avoiding the need to replace the punch 21 due to the length of the impact piece 212 making it difficult to complete the punching operation of the thicker workpiece a to be processed. The depth of the groove is greater than or equal to 5mm, and the diameter of the groove is adjusted according to the required punching diameter. In the embodiment of the utility model, it is preferably greater than or equal to 2mm. The impact piece 212 of the punch 21 forms a gap b with the groove when the punching is completed, and the gap b is formed by the diameter of the impact piece 212 being less than the diameter of the groove by 100μm. The gap b formed by the difference between the diameter of the impact piece 212 and the diameter of the groove ensures that the punching size of the punch 21 meets the required size requirements, and that no bulges are formed on the edge of the hole along the punching direction to affect the processing quality of the hole. It also ensures that the punch 21 can be smoothly withdrawn from the groove and the hole of the workpiece to be processed when the punching operation is completed, avoiding the punch 21 from fitting tightly with the groove and the processed hole, which makes it impossible to smoothly withdraw the punch 21, thereby affecting the subsequent processing operations of the processing device 1000.

[0037] It is worth noting that the gap b is evenly distributed between the impact piece 212 and the inner wall of the groove, so that the position and size of the punched hole formed meet the processing requirements.

[0038] It is worth noting that when the required processing diameter of the hole of the workpiece a is 2 mm, the difference between the diameter of the impact piece 212 and the diameter of the groove is 100 μm, that is, in the cross-sectional view along the stamping direction, a gap of 50 μm is left on one side, the processing completion degree of the required hole is relatively ideal, and there will be no bulge formed on the edge of the hole formed by stamping.

[0039] It is understandable that the depth of the groove needs to be selected according to the actual processing conditions, and is therefore not limited to a depth greater than or equal to 5 mm, but can also be less than 5 mm, as long as there is sufficient margin to ensure that the punch 21 can be accommodated in the groove.

[0040] In order to facilitate understanding of the technical solution of the utility model, an example is now given of the punching process of the LCP board based on the processing device 1000. The specified LCP board is preset with multiple blind holes with a diameter of 3.5 mm, wherein the depth of the blind holes needs to be adjusted according to the number of layers of the LCP board. When the number of layers of the LCP board is 4, the depth of the blind holes is the thickness of 3 layers of the LCP board. When the number of layers of the LCP board is 15, the depth of the blind holes is the thickness of 14 layers of the LCP board. In this embodiment, the number of layers of the specified LCP board is 10, the depth of the blind holes is the thickness of 9 layers of the LCP board, and the required punching size of the specified LCP board is 2 mm. The length of the impact piece 212 of the specified punch 21 is 10 mm. The groove depth of the specified support member 31 is 5 mm, and the groove diameter is 2 mm.

[0041] like Figure 3 As shown, when the stamping assembly 2 punches the LCP plate, the surface of the LCP plate with the preset blind hole (not marked) faces the support assembly 3, and each support member 31 is received in each blind hole, the top of the support member 31 abuts the bottom wall of the blind hole, and the side wall of the support member 31 abuts the side wall of the blind hole, so that the support member 31 forms a horizontal limit for the LCP plate. The stamping assembly 2 is driven by the power device 1 so that the center line of each punch 21 coincides with the center line of each support member 31, and the stamping assembly 2 is driven by the power device 1 to approach the support assembly 3. After the stamping is completed, the stamping assembly 2 is driven away from the support assembly 3, thereby completing the complete punching process of the LCP plate, thereby obtaining a processing as shown. Figure 3 The final product on display.

[0042] For the above-mentioned power device 1, the power device 1 also includes a first moving assembly (not shown) and a second moving assembly (not shown), the first moving assembly connects a plurality of punches 21, and the first moving assembly is used to control the reciprocating movement of the plurality of punches 21 along the first direction, that is, the direction in which the punches 21 are vertically close to or away from the support assembly 3, so that the plurality of punches 21 are close to the support assembly 3 or away from the support assembly 3, so that the punches 21 complete the punching operation and the operation of disengaging from the support member 31, which is convenient for the subsequent processing of the remaining workpieces a to be processed, and improves the efficiency of batch processing. The first moving assembly is connected to the second moving assembly, and the second moving assembly is used to drive the first moving assembly to move along the second direction, that is, to make the first moving assembly move in the horizontal direction, wherein the first direction and the second direction are perpendicular. The second moving assembly enables the first moving assembly to move away from the support assembly 3 or close to the support assembly 3 in the horizontal direction, thereby facilitating the installation and maintenance of the stamping assembly 2, and avoiding that the stamping assembly 2 can only be located directly above the support assembly 3 during the installation and maintenance process, thereby causing some impurities to fall on the support assembly 3 and affect the punching effect of the processing device 1000.

[0043] In some embodiments, the power device 1 also includes a sensing device (not shown) and a controller (not shown). The sensing device is fixed to the connecting member 211. It is worth noting that the installation of the sensing device does not affect the stamping function of the punch 21. The sensing device is used to detect the distance between the punch 21 and the workpiece a to be processed and generate a corresponding feedback signal; the controller is electrically connected to the sensing device, and the controller is used to receive and process the feedback signal and control the movement of the power device 1. According to the received feedback signal, the controller can analyze and process the feedback signal and determine the distance between the stamping assembly 2 and the workpiece a to be processed at this time, thereby analyzing the sheet thickness of the workpiece to be processed, and then driving the first moving assembly to move in a direction away from or close to the workpiece a to be processed, thereby realizing dynamic adjustment of the sheet thickness of different workpieces a to be processed, thereby achieving more ideal stamping processing conditions.

[0044] In some embodiments, the stamping assembly 2 also includes a plurality of connecting strips (not shown), the plurality of connecting strips are inserted into the slide grooves of the power device 1, and a plurality of punches 21 are evenly fixed to the plurality of connecting strips; the support assembly 3 also includes a support plate (not shown), and a plurality of support members 31 are fixed to the support plate in a rectangular array; wherein, one punch 21 corresponds to one support member 31.

[0045] It can be understood that the existence of the connecting strip makes the installation of the punch 21 more convenient, and reduces the time cost of the later installation and maintenance of the punch 21. Of course, this connecting strip can be provided with a plurality of installation grooves, and the bottom wall of the installation groove is provided with a mounting hole. After the impact piece 212 of each punch 21 passes through the mounting hole, the connecting piece 211 of each punch 21 is accommodated in the mounting groove, and the mounting groove is adapted to the shape of the connecting piece 211, so as to avoid the punch 21 from shaking in the mounting groove, thereby avoiding the situation where the entire connecting strip must be replaced due to damage to a certain punch 21, thereby reducing the maintenance cost; similarly The presence of the support plate also makes the installation and maintenance of the support member 31 more convenient, and the support plate may also be provided with a plurality of second installation grooves, which are used to accommodate the support members 31. This design greatly increases the adaptability range of the support assembly 3. If there is a need to replace support members 31 of different diameters and depths, it is only necessary to remove and replace the support members 31 from the support plate, and personalized matching of multiple support members 31 in different areas of the support plate can be achieved, thereby meeting the customization requirements of the support assembly 3 and reducing the subsequent maintenance costs of the support members 31.

[0046] In some embodiments, the stamping assembly 2 further includes at least two guide posts (not shown), which are fixed to the power device 1, and at least two guide posts are fixed to both sides of the stamping assembly 2, and the guide posts can move with the power device 1; the support assembly 3 further includes at least two guide holes (not shown), which are arranged on the support plate; wherein one guide post corresponds to one guide hole. When the stamping assembly 2 performs a stamping operation, a guide post is inserted into a guide hole, and the guide post is inserted into the guide hole to guide the stamping assembly 2 to move in the first direction, thereby improving the stamping processing positioning accuracy of the stamping assembly 2.

[0047] In some embodiments, the processing device 1000 further includes an infrared positioning mechanism (not shown), which is used to detect the specific position of the power device 1. Specifically, the infrared positioning mechanism includes an infrared emitting component and an infrared receiving component, wherein the infrared emitting component is fixed to the power device 1, and the infrared receiving component is fixed to the platform for holding the support component 3, wherein the infrared emitting component is used to emit infrared signals, and the infrared receiving component is used to receive infrared signals, and both the infrared emitting component and the infrared receiving component are electrically connected to the controller. When the power device 1 moves to a preset position, the preset position means that the power device is located directly above the support component, the infrared signal emitted by the infrared emitting component is successfully received by the infrared receiving component, and reaches the preset infrared signal receiving strength, thereby determining that the power device 1 is at the preset position at this time, and subsequent processing steps can be performed.

[0048] It can be understood that the infrared positioning mechanism can also be replaced by probes and contacts, laser positioning and radar positioning, etc. The specific application layout and working principle will not be described in detail in this embodiment.

[0049] In the embodiment of the utility model, the processing device 1000 includes a power device 1, a stamping assembly 2, a support assembly 3 and a processing table 4. The stamping assembly 2 includes a plurality of punches 21; the plurality of punches 21 are evenly distributed according to preset positions, the power device 1 is connected to the plurality of punches 21, and is used to provide power for the stamping assembly 2; the support assembly 3 includes a plurality of support members 31, the support members 31 are provided with grooves, and the plurality of support members 31 are used to abut and support the workpiece a to be processed, one groove corresponds to one punch 21, and the groove is used to accommodate the punch 21 when the punch 21 completes punching the workpiece a to be processed, and the processing table 4 is used to hold the support assembly 3. The workpiece a to be processed is extruded by the punch 21, and the support member 31 provides a supporting force for the workpiece a to be processed, and the interaction between the two forms a shearing effect on the workpiece a to be processed, thereby realizing the punching operation of the workpiece a to be processed.

[0050] The utility model also provides an assembly line embodiment, the assembly line includes the above-mentioned processing device 1000, the structure and function of the assembly line can refer to the above-mentioned embodiment, and will not be described one by one here.
