Description

Technical Field

[0001] This invention belongs to the field of composite pad production technology, specifically relating to an automatic forming production device for composite pads for printed circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are substrates used to assemble electronic components. Their main function is to connect various electronic components into predetermined circuits and act as relays. They are key electronic interconnects in electronic products. This interconnection of electronic components requires drilling holes in the PCB to fix and connect the electronic components. To avoid scratching the PCB when drilling holes, a composite pad is usually placed underneath the PCB.

[0003] In the existing composite pad manufacturing process, the process usually involves impregnation with glue, drying, and pressing. After pressing and molding, the pad needs to be cut on another device. Generally, when the cutting machine cuts the pad, the pad is placed on the cutting platform and cut directly. Due to the lack of limiters or manual pressing of the pad during cutting, the fixing effect is poor, and the pad will shift during cutting, resulting in processing errors. Summary of the Invention

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the present invention aims to provide an automatic forming production device for printed circuit board composite pads. This automatic forming production device aims to solve the technical problems in the existing composite pad manufacturing process, where the board is placed on a cutting platform for direct cutting. Due to the lack of limiting devices or manual pressing of the board during cutting, the fixing effect is poor, and the board displacement during cutting leads to processing errors.

[0007] Furthermore, the front and rear adjustment assembly includes a second motor fixedly connected to the front of the side plate, a second lead screw fixedly connected to the output end of the second motor, the back of the second lead screw passing through the movable block and rotatably connected to the rear side plate, the second lead screw being threadedly connected to the movable block, a slide rod fixedly connected to the front of the rear side plate, the front of the slide rod passing through the movable rod and fixedly connected to the front side plate, and the slide rod being slidably connected to the movable rod.

[0008] Furthermore, the up-and-down adjustment assembly includes a vertical plate fixedly connected to the right side of the movable block, a mounting plate slidably connected to the right side of the vertical plate, a cutting machine fixedly connected to the bottom end of the mounting plate, a fixed seat fixedly connected to the right side of the mounting plate, and an electric push rod fixedly connected to the top right side of the vertical plate, with the output end of the electric push rod fixedly connected to the fixed seat.

[0009] Furthermore, two sliders are fixedly connected to the left side of the mounting plate, and a sliding groove corresponding to the sliders is opened on the right side of the upright plate.

[0010] Furthermore, reinforcing plates are fixedly connected to both the front and rear sides of the movable block, and the other end of the reinforcing plates is fixedly connected to the upright plate.

[0011] Furthermore, the pressing assembly includes multiple fixed cylinders fixedly connected to the lower surface of the movable rod. A pressing rod is slidably connected to the bottom end of the fixed cylinder. A rubber block is fixedly connected to the bottom end of the pressing rod. The top end of the pressing rod is located inside the fixed cylinder and is fixedly connected to a limit block. A first spring is fixedly connected between the limit block and the inner wall of the fixed cylinder.

[0012] Furthermore, a connecting plate is fixedly connected to the top of the side plate, and two round rods are fixedly connected to the lower surface of the connecting plate. The bottom end of the round rod passes through the movable rod and is fixedly connected to a stop block. The round rod and the movable rod are slidably connected, and a second spring is sleeved on the outer surface of the round rod.

[0013] Furthermore, the auxiliary components include a rotating rod rotatably connected between the two side plates, with multiple auxiliary rods fixedly connected to the left side of the rotating rod, and auxiliary rollers rotatably connected to the other end of the auxiliary rods via pins.

[0015] (3) Beneficial effects Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a left-right adjustment component to move a push plate to the right. During this movement, the push plate moves the sheet metal below the cutting machine. Then, a right-up adjustment component moves the cutting machine downwards. Next, a left-right adjustment component moves a movable block and the cutting machine forward. Simultaneously, as the movable block moves forward, it causes a cylinder to slide into a groove. At this point, the movable rod slides downwards along the cylinder and compresses the second spring. The auxiliary component then presses the sheet metal, thereby positioning it and enabling multiple cuts at different positions without manual intervention. This improves work efficiency and prevents errors during cutting.

[0016] In the above solution, by setting up auxiliary components, the drive cylinder drives the rotating rod to rotate via the drive rod. During the rotation of the rotating rod, it can drive the auxiliary rod and auxiliary roller to rotate until the auxiliary roller presses against the board. The left and right adjustment components can drive the push plate to move to the right. At this time, since the auxiliary roller can roll along the board, the push plate can drive the board to continue to move a certain length for cutting during the movement. Thus, the auxiliary components press the board, making the board flatter and improving production quality. Attached Figure Description

[0019] This specific embodiment is an automated forming production device for composite pads on printed circuit boards, and its structural schematic diagram is shown below. Figures 1-7 As shown, the automatic molding production device includes a base 1, an operating table 2 fixedly connected to the upper surface of the base 1, a push plate 4 set on the left side of the operating table 2 via a left-right adjustment component 3, two side plates 5 fixedly connected to the right side of the operating table 2, a movable block 7 set between the two side plates 5 via a front-back adjustment component 6, a cutting machine 9 set on the right side of the movable block 7 via a vertical adjustment component 8, a movable rod 10 set on the left side of the movable block 7, a slide groove 11 opened on the right side of the movable rod 10, both the front and rear ends of the slide groove 11 are flared, and as the movable block 7 moves forward, it drives the cylinder 12 to slide into the slide groove 11, at which time the movable rod 10 will move downward, the left side of the movable block 7 is rotatably connected to the cylinder 12 corresponding to the slide groove 11, pressing components 13 are installed on both the front and rear sides of the movable rod 10, and an auxiliary component 14 is set on the left side of the pressing component 13.

[0020] like Figure 1 and Figure 4As shown, in this embodiment, the left and right adjustment component 3 includes a groove 301 formed on the lower surface of the operating table 2. The operating table 2 has an elongated hole 302 communicating with the groove 301. A movable plate 303 is provided inside the groove 301. The top end of the movable plate 303 is fixedly connected to the push plate 4 through a vertical rod 307 and the elongated hole 302. A guide rod 304 is fixedly connected to the rear side of the left inner wall of the groove 301. The right end of the guide rod 304 passes through the movable plate 303 and is fixedly connected to the right inner wall of the groove 301. The guide rod 304 is slidably connected to the movable plate 303. A first motor 305 is fixedly connected to the front side of the right inner wall of the groove 301. A first lead screw 306 is fixedly connected to the output end of the first motor 305. The left end of the first lead screw 306 passes through the movable plate 303 and is rotatably connected to the left inner wall of the groove 301. The first motor 305 is threadedly connected to the movable plate 303.

[0021] This setup starts the first motor 305, which drives the first lead screw 306 to rotate. Since the first lead screw 306 is threadedly connected to the movable plate 303, the first lead screw 306 can drive the movable plate 303, the vertical rod 307, and the push plate 4 to move to the right during the rotation. During the movement, the push plate 4 can move the plate to the bottom of the cutting machine 9.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, the front and rear adjustment assembly 6 includes a second motor 601 fixedly connected to the front of the side plate 5. The output end of the second motor 601 is fixedly connected to a second lead screw 602. The back of the second lead screw 602 passes through the movable block 7 and is rotatably connected to the rear side plate 5. The second lead screw 602 is threadedly connected to the movable block 7. The front of the rear side plate 5 is fixedly connected to a slide rod 603. The front of the slide rod 603 passes through the movable rod 10 and is fixedly connected to the front side plate 5. The slide rod 603 is slidably connected to the movable rod 10.

[0023] This setup starts the second motor 601, which drives the second lead screw 602 to rotate. Since the second lead screw 602 is threadedly connected to the movable block 7, the second lead screw 602 can drive the movable block 7 and the cutting machine 9 to move forward and cut the plate during the rotation.

[0024] like Figure 2 and Figure 6 As shown, in this embodiment, the up-down adjustment component 8 includes a vertical plate 801 fixedly connected to the right side of the movable block 7, a mounting plate 802 slidably connected to the right side of the vertical plate 801, a cutting machine 9 fixedly connected to the bottom end of the mounting plate 802, a fixed seat 803 fixedly connected to the right side of the mounting plate 802, an electric push rod 804 fixedly connected to the top right side of the vertical plate 801, the output end of the electric push rod 804 fixedly connected to the fixed seat 803, and the operating table 2 is provided with a clearance groove corresponding to the cutting machine 9 to prevent damage to the operating table 2.

[0025] This configuration allows the electric push rod 804 to extend and move the fixed base 803 and mounting plate 802 downwards. During this movement, the mounting plate 802 can move the cutting machine 9 downwards, enabling the cutting machine 9 to cut the sheet material.

[0026] like Figure 6 As shown, in this embodiment, two sliders 805 are fixedly connected to the left side of the mounting plate 802, and a sliding groove 806 corresponding to the sliders 805 is provided on the right side of the upright plate 801.

[0027] This arrangement of slider 805 and sliding groove 806 guides the movement of mounting plate 802, making the up-and-down movement of mounting plate 802 more stable and preventing tilting.

[0028] like Figure 2 and Figure 6 As shown, in this embodiment, reinforcing plates 807 are fixedly connected to both the front and rear sides of the movable block 7, and the other end of the reinforcing plate 807 is fixedly connected to the upright plate 801. This arrangement makes the connection between the movable block 7 and the upright plate 801 more secure.

[0029] like Figure 5 and Figure 7 As shown, in this embodiment, the pressing assembly 13 includes a plurality of fixed cylinders 1302 fixedly connected to the lower surface of the movable rod 10. A pressing rod 1303 is slidably connected to the bottom end of the fixed cylinder 1302. A rubber block 1304 is fixedly connected to the bottom end of the pressing rod 1303. The top end of the pressing rod 1303 is located inside the fixed cylinder 1302 and is fixedly connected to a limiting block 1305. A first spring 1306 is fixedly connected between the limiting block 1305 and the inner wall of the fixed cylinder 1302.

[0030] When the rubber block 1304 comes into contact with the plate, the limiting block 1305 at the top of the pressing rod 1303 slides in the fixed cylinder 1302 and compresses the first spring 1306. The restoring force of the first spring 1306 causes the rubber block 1304 to press the plate, thereby positioning the plate and preventing errors during cutting.

[0031] like Figure 2 and Figure 5 As shown, in this embodiment, a connecting plate 1307 is fixedly connected to the top of the side plate 5, and two round rods 1308 are fixedly connected to the lower surface of the connecting plate 1307. The bottom end of the round rod 1308 passes through the movable rod 10 and is fixedly connected to a stop block 1309. The round rod 1308 is slidably connected to the movable rod 10, and a second spring 1310 is sleeved on the outer surface of the round rod 1308.

[0032] In this configuration, as the movable block 7 moves forward, it causes the cylinder 12 to slide into the groove 11. At this time, the movable rod 10 slides down along the rod 1308 and compresses the second spring 1310, and is reset by the restoring force of the second spring 1310.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the auxiliary component 14 includes a rotating rod 1401 rotatably connected between two side plates 5. A plurality of auxiliary rods 1402 are fixedly connected to the left side of the rotating rod 1401. The other end of the auxiliary rod 1402 is rotatably connected to an auxiliary roller 1403 via a pin. A driving component is provided on the front side of the side plate 5. The driving component includes a driving cylinder 1404 rotatably connected to the front side of the side plate 5. The output end of the driving cylinder 1404 is rotatably connected to a driving rod 1405 via a pin. The other end of the driving rod 1405 is rotatably connected to the front side of the rotating rod 1401.

[0034] This configuration allows the start-up drive cylinder 1404 to extend, which in turn drives the rotating rod 1401 to rotate via the drive rod 1405. During the rotation, the rotating rod 1401 drives the auxiliary rod 1402 and the auxiliary roller 1403 to rotate until the auxiliary roller 1403 presses firmly onto the plate.

[0035] The technical solution provided by this invention involves placing the sheet material on the operating table 2, with its left side close to the push plate 4. Then, the first motor 305 is started, driving the first lead screw 306 to rotate. Since the first lead screw 306 is threadedly connected to the movable plate 303, its rotation causes the movable plate 303, vertical rod 307, and push plate 4 to move to the right. During this movement, the push plate 4 moves the sheet material below the cutting machine 9. Then, the drive cylinder 1404 is extended, driving the rotating rod 1401 to rotate via the drive rod 1405. The rotating rod 1401 rotates, driving the auxiliary rod 1402 and auxiliary roller 1403 until the auxiliary roller 1403 presses firmly onto the sheet material. Then, the electric push rod 804 is extended, causing the fixed base 803 and mounting plate 802 to move downwards. During this movement, the mounting plate 802 moves the cutting machine 9 downwards. The second motor 601 is started, which drives the second lead screw 602 to rotate. Since the second lead screw 602 is threadedly connected to the movable block 7, the second lead screw 602 can drive the movable block 7 and the cutting machine 9 to move forward during the rotation. At the same time, the movable block 7 drives the cylinder 12 to slide into the slide groove 11 during the forward movement. At this time, the movable rod 10 slides down along the rod 1308 and compresses the second spring 1310. When the rubber block 1304 contacts the plate, the limiting block 1305 at the top of the pressing rod 1303 slides in the fixed cylinder 1302 and compresses the first spring 1306. The restoring force of the first spring 1306 makes the rubber block 1304 press the plate, thereby positioning the plate and preventing errors during cutting. This continues until the cutting machine 9 moves to the front and cuts the plate. Then it resets backward, the cylinder 12 disengages from the slide groove 11, and the restoring force of the second spring 1310 resets the rubber block 1304. Then, the first motor 305 is started to drive the first lead screw 306 to rotate. Since the first lead screw 306 is threadedly connected to the movable plate 303, the first lead screw 306 can drive the movable plate 303, the vertical rod 307 and the push plate 4 to move to the right during the rotation. Since the auxiliary roller 1403 can roll along the plate, the push plate 4 can drive the plate to continue to move a certain length during the movement, and then cut again.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
