Description

Technical Field

[0001] The utility model relates to the technical field of PCB production devices, in particular to a compatible PIN mechanism for a multi-layer double-sided circuit board. Background Art

[0002] In the current PCB production process, multi-layer and double-sided circuit boards are placed in separate stations during the PIN process. The main reason is that multi-layer circuit boards have their own PIN holes. Therefore, during the PIN process, after the multi-layer circuit board is transported to the PIN station, it is positioned by passing a positioning pin through the PIN hole of the multi-layer circuit board before the PIN pin is implanted. Double-sided circuit boards do not have PIN holes. Therefore, during the PIN process, after the double-sided circuit board is transported to the PIN station, the PIN hole needs to be punched before the PIN pin is implanted.

[0003] In order to make the production line compatible with the production processes of multi-layer circuit boards and double-sided circuit boards, existing equipment will simultaneously set the positioning and drilling in the same upper PIN station. For example, referring to the Chinese utility model patent with announcement number CN208317124U, it discloses a device for PINing single-layer and double-layer PCBs and multi-layer boards. When the board is a multi-layer board with pre-set PIN holes, the pre-positioning pin component is inserted into the PIN hole to complete the pre-alignment, and the re-positioning pin component is raised and inserted into the PIN hole to complete the re-positioning; when the board is a single-layer or double-layer board without PIN holes, the four-side clapper component aligns the four sides of the board, and the air avoidance module is pressed down while the drilling component rises to drill; the re-positioning pin component is lowered and retracted before the single-layer or double-layer board is placed, integrating the two upper PIN processes into one and mechanizing them, thereby improving production efficiency.

[0004] However, the above-mentioned prior art still has some shortcomings. For example, the arrangement direction of the repositioning pin module and the drilling module in the pin planting mechanism is perpendicular to the conveying direction of the conveying mechanism. Then, when drilling or positioning at the same position of the PCB board, the contact area between the two types of plates and the table will be significantly different. When the plate is a double-sided circuit board, a drilling component is required to drill holes. At this time, the contact area between the double-sided circuit board and the table is large, which makes it easy for the double-sided circuit board to rub against the table and cause damage. In addition, the arrangement direction of the repositioning pin module, the drilling module and the PIN pressing pin module is also perpendicular to the conveying direction of the conveyor line. The drilling module is sandwiched between the repositioning pin module and the PIN pressing pin module. When replacing the drill bit of the drilling module, it is greatly interfered with by the repositioning pin module and the PIN pressing pin module, and it is inconvenient to replace the drill bit. Utility Model Content

[0021] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when a multi-layer circuit board needs to be subjected to a PIN process, the X-direction driving component drives the punching bracket to move along the X-direction, so that the guide pin and the output end of the PIN pin assembly are vertically opposed to each other, and the guide pin passes through the PIN hole of the multi-layer circuit board for positioning.

In this way, corresponding switching can be performed according to different incoming materials to meet production needs.

[0022] By arranging the guide pins and punching tool along the X-direction and adjusting their positions in the X-direction using the X-direction drive component according to actual production, the contact area between the guide pins and the punching tool and the board surface is the same, regardless of whether it is a multi-layer circuit board or a double-sided circuit board.

[0023] It is worth noting that the guide pins and punching tools are arranged along the X direction, which can make the size of the plate placement surface along the Y direction smaller, reducing the contact area between the PCB board and the plate placement surface. Then, when the punching bracket is reset along the Y direction, the friction area between the PCB board and the plate placement surface is also smaller, thereby reducing the loss to the PCB.

[0024] In addition, because the guide pin is located in the X direction of the punching spindle, the punching tool will not be sandwiched between the PIN pin assembly and the guide pin. When the punching tool is replaced in the positioning punching assembly, the interference of the guide pin with the operation of replacing the punching tool can be reduced, thereby improving the convenience of the operation of replacing the punching tool. In the utility model, when the punching tool needs to be replaced, the X-direction driving component drives the punching bracket to move along the X direction, so that the punching tool moves along the X direction to one side of the PIN pin assembly along the X direction, thereby reducing the interference of the PIN pin assembly with the operation of replacing the punching tool and improving the convenience of the operation of replacing the punching tool.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0044] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or solutions that meet both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0045] The utility model provides a multi-layer double-sided circuit board compatible with a PIN mechanism.

[0046] See also Figures 1-15The multi-layer double-sided circuit board compatible PIN mechanism proposed by the present invention includes: a frame 1; two Y-direction driving components 2, the Y-direction driving components 2 are relatively arranged on both sides of the interior of the frame 1, and the two Y-direction driving components 2 have slides that move along the Y direction, and the moving directions of the two slides are opposite; two planting PIN pin assemblies 3, the two planting PIN pin assemblies 3 are arranged on the upper surfaces of the two slides in a one-to-one correspondence; two positioning punching assemblies 4, the two positioning punching assemblies 4 are arranged on the upper surfaces of the two slides in a one-to-one correspondence; the two positioning punching assemblies 4 respectively include an X-direction driving component 401, a punching bracket 402, a positioning unit 403 and a punching unit 404, the X-direction driving component 4 01 is arranged on the upper surface of the slide, and the movable end of the X-direction driving component 401 moves along the X-direction; the punching bracket 402 is located below the PIN pin assembly 3, and the upper end of the punching bracket 402 is provided with a plate placement surface, and the punching bracket 402 is connected to the movable end of the X-direction driving component 401 to move along the X-direction with the movable end of the X-direction driving component 401; the positioning unit 403 and the punching unit 404 are both arranged in the punching bracket 402, the positioning unit 403 has a guide pin 4031 that can pass through the plate placement surface, and the punching unit 404 has a punching tool 4041 that can pass through the plate placement surface, and the guide pin 4031 and the punching tool 4041 are arranged along the X-direction.

[0047] Specifically, in actual applications, when a multi-layer circuit board needs to be PIN-applied, the X-direction drive component 401 drives the punching bracket 402 to move in the X-direction, so that the guide pin 4031 is vertically aligned with the output end of the PIN-applying pin assembly 3, thereby positioning the guide pin 4031 through the PIN hole of the multi-layer circuit board. When a double-sided circuit board needs to be PIN-applied, the X-direction drive component 401 drives the punching bracket 402 to move in the X-direction, so that the punching tool 4041 is vertically aligned with the output end of the PIN-applying pin assembly 3, thereby drilling PIN holes at corresponding positions on the double-sided circuit board.

[0048] In the present invention, the guide pins 4031 and the punching tool 4041 are arranged along the X direction, and the positions of the guide pins 4031 and the punching tool 4041 in the X direction are adjusted according to actual production by the X-direction driving component 401. In this way, whether it is a multi-layer circuit board or a double-sided circuit board, the contact area between the two and the board surface is the same.

[0049] It is worth noting that the guide pin 4031 and the punching tool 4041 are arranged along the X direction, which can make the size of the plate placement surface along the Y direction smaller, reducing the contact area between the PCB board and the plate placement surface. Then, when the punching bracket 402 is reset along the Y direction, the friction area between the PCB board and the plate placement surface is also smaller, thereby reducing damage to the PCB.

[0050] In addition, since the positioning unit 403 is located in the X direction of the punching unit 404, the punching unit 404 will not be sandwiched between the PIN planting pin assembly 3 and the positioning unit 403. When the punching tool 4041 of the positioning punching assembly 4 is replaced, the interference of the positioning unit 403 with the operation of replacing the punching tool 4041 can be reduced, thereby improving the convenience of replacing the punching tool 4041. In this embodiment, when the punching tool 4041 needs to be replaced, the X-direction driving component 401 drives the punching bracket 402 to move along the X direction, so that the punching tool 4041 moves along the X direction to one side of the PIN planting pin assembly 3 along the X direction, thereby reducing the interference of the PIN planting pin assembly 3 with the operation of replacing the punching tool 4041, thereby improving the convenience of replacing the punching tool 4041.

[0051] See also Figure 4 In a preferred embodiment of the present invention, the PIN mechanism 3 includes an upper PIN bracket 301, a punching cylinder 302, and an upper PIN pressing head 303. The upper PIN bracket 301 is arranged at the upper end of the Y-direction driving component 2 in the height direction, the punching cylinder 302 is arranged at the upper end of the upper PIN bracket 301 in the height direction, and the upper PIN pressing head 303 is connected to the output end of the punching cylinder 302. In addition, a vibrating material disk and a feeding pipe are also provided at the upper end of the upper PIN bracket 301. When the vibrating material disk is activated, the PIN needle inside it is transported through the feeding pipe to the upper PIN pressing head 303 for the PIN operation. Since this part belongs to the existing technology, it will not be elaborated in detail. When in use, the PIN needle enters the feeding pipe from the vibrating material disk and then enters the upper PIN pressing head 303. The punching cylinder 302 is activated, driving the upper PIN pressing head 303 to press down to achieve the PIN operation.

[0052] See also Figure 5 In a preferred embodiment of the present invention, the positioning unit 403 further comprises a first lifting portion 4032 disposed within the punching bracket 402. The lifting end of the first lifting portion 4032 is connected to the guide pin 4031 to drive the guide pin 4031 to rise and pass through the sheet placement surface and to drive the guide pin 4031 to return to its position below the sheet placement surface. The punching unit 404 further comprises a punching spindle 4042 and a second lifting portion 4043 disposed within the punching bracket 402. The punching spindle 4042 is connected to the punching tool 4041. The second lifting portion 4043 is connected to the punching spindle 4042 to drive the punching spindle 4042 to rise and fall, thereby causing the punching tool 4041 to pass through and return below the sheet placement surface.

[0053] In addition, a dust collection component is provided in the punching bracket 402 for collecting debris generated by the punching and PINing processes. Since this technical solution is a prior art, it will not be elaborated on in detail.

[0054] See also Figures 9-12In a preferred embodiment of the present invention, it further includes a carrying component 5, which is located between the two positioning punching components 4. The carrying component 5 includes a carrying plate 501, two placement racks 502, two baffles 503 and a first adjusting component 504. The carrying plate 501 is arranged inside the frame 1, and the first adjusting component 504 is arranged at the upper end of the carrying plate 501 in the thickness direction. The two placement racks 502 are both arranged at the upper end of the height direction of the first adjusting component 504. The first adjusting component 504 drives the two placement racks 502 to move along the X direction, and the two placement racks 502 move in opposite directions. The PCB board is placed at the upper end of the placement rack 502 in the height direction, and the two baffles 503 are arranged on the opposite sides of the two placement racks 502.

[0055] With the above technical solution, when in use, a PCB board waiting for punching and PIN insertion is transferred to the placement rack 502. By activating the first adjustment component 504, the first adjustment component 504 drives the two placement racks 502 closer together, and the placement racks 502 drive the baffles 503 closer together. If the transferred PCB board is skewed, the baffles 503 contact the side of the PCB board, and the two baffles 503 move relative to each other, pushing the PCB board to rotate, so that the skewed PCB board is straightened, thereby preventing the PCB board from being skewed and affecting the qualified rate of punching or PIN insertion.

[0056] See also Figures 9-12 In a preferred embodiment of the present invention, the supporting component 5 also includes a first cylinder 506 and a pressure plate 507. The first cylinder 506 is arranged at the opposite end of the two placement racks 502, and the pressure plate 507 is arranged at the output end of the first cylinder 506. The pressure plate 507 is used to press the PCB board placed at the upper end of the placement rack 502 in the height direction.

[0057] Through the above technical solution, during the board making process, the height of the pressing plate 507 can be adjusted by the first cylinder 506, and the pressing plate 507 can be used to press the PCB board placed on the placement rack 502, which can effectively prevent the PCB board from moving during the punching or PIN process.

[0058] Furthermore, in this embodiment, a support frame 508 is provided. The support frame 508 is located between the two placement frames 502, and the support frame 508 is fixedly connected to the carrier plate 501. After the PCB board is placed on the carrier component 5, the support frame 508 can support the middle part of the PCB board to prevent the middle part from collapsing.

[0059] See also Figures 9-12In a preferred embodiment of the present invention, the first adjusting component 504 includes a first adjusting motor 5041, a first tensioning wheel 5042, a second tensioning wheel 5043, a transmission belt 5044 and a first adjusting slide rail 5045. The first adjusting motor 5041 is arranged at the lower end of the carrier plate 501 in the thickness direction. The output end of the first adjusting motor 5041 passes through the carrier plate 501 and extends to the upper end of the carrier plate 501 in the thickness direction.
