Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a welding sheet conveying device. Background Technology

[0002] PCBN (polycrystalline cubic boron nitride) inserts can be classified into three types according to their manufacturing process: integral sintered type, composite welded type, and integral welded type. Integral sintered type: entirely made of PCBN material, without solder pads, offering multiple cutting edges and eliminating the risk of brazing failure. Composite welded type: small PCBN insert tips are brazed to a cemented carbide substrate using solder pads as the connecting medium. Integral welded type: employs an "integral U-shaped through-hole design," combining the PCBN insert with the substrate through high-vacuum brazing, with the solder pads enhancing structural strength and impact resistance. In the case of production overload, integral welded inserts require a stable input of solder pads. A stable supply of solder pads determines the stable production line of the tool; therefore, a solder pad delivery device with the advantage of stable output of individual solder pads is needed to ensure a stable supply of solder pads. Summary of the Invention

[0003] The purpose of this utility model is to provide a welding sheet conveying device, which has the advantage of stable output of a single welding sheet, thus ensuring a stable supply of welding sheets.

[0004] The technical solution adopted is as follows:

[0005] A welding sheet conveying device includes a support platform, a column above the support platform, a hopper with openings at the top and bottom on the side of the column, the distance between the hopper and the support platform being 1.5 times the thickness of the welding sheet, a crossbeam rotatably mounted on the upper end of the column, a first telescopic rod vertically mounted at the end of the crossbeam, a pressure plate mechanism mounted at the lower end of the first telescopic rod, a push plate horizontally sliding on the upper end of the support platform, the thickness of the push plate being two-thirds of the thickness of the welding sheet, a limit notch being provided at the end of the push plate, and a second telescopic rod horizontally mounted on the hopper connected to the push plate.

[0006] Preferably, the pressure plate mechanism includes a top plate and a bottom plate, and a compression spring is provided between the top plate and the bottom plate.

[0007] Preferably, the compression spring is provided with a limiting tube and a limiting shaft on its inner side, the limiting tube being fixedly connected to the top plate and the limiting shaft being fixedly connected to the bottom plate.

[0008] Preferably, both the first telescopic rod and the second telescopic rod are electric telescopic rods. A controller connected to both the first telescopic rod and the second telescopic rod is provided on the upper end of the support platform. A limit switch corresponding to the push plate is provided on the upper end of the support platform, and the limit switch is connected to the controller.

[0009] Preferably, the lower end face of the push plate is provided with multiple mounting grooves, and each mounting groove is rotatably equipped with a roller.

[0010] Compared to existing technologies, the advantages are:

[0011] Multiple solder pads are stacked together and placed in the hopper. The top solder pad is held down by the first telescopic rod and the pressure plate mechanism connected to the lower end. The second telescopic rod controls the push plate to move back and forth. During the back and forth movement, the bottom solder pad is pushed out from the bottom of the hopper, ensuring a continuous and stable supply of individual solder pads and ensuring the stable and normal operation of the overall solder pad structure PCBN blade welding process.

[0016] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0017] Example 1: A welding sheet conveying device includes a support platform 1, a column 2 above the support platform 1, and a hopper 3 with openings at the top and bottom on the side of the column 2. The hopper 3 is fixedly connected to the column 2 by a connecting beam. The internal shape of the hopper 3 is consistent with the shape of the welding sheet placed horizontally. The welding sheet slides vertically in the hopper 3 and does not slide horizontally under the limit of the hopper 3. The distance between the hopper 3 and the support platform 1 is 1.5 times the thickness of the welding sheet, ensuring that one welding sheet can slide out stably from the gap between the hopper 3 and the support platform 1, and two welding sheets cannot slide out from the gap between the hopper 3 and the support platform 1 at the same time.

[0018] A crossbeam 4 is rotatably mounted on the upper end of the column 2. A first telescopic rod 5 is vertically mounted on the end of the crossbeam 4. A pressure plate mechanism is mounted on the lower end of the first telescopic rod 5. The first telescopic rod 5 controls the pressure plate mechanism to press down. The first telescopic rod 5 and the pressure plate mechanism connected to the lower end press down on the uppermost welding piece. A push plate 11 is horizontally slidably mounted on the upper end of the support platform 1. The thickness of the push plate 11 is two-thirds of the thickness of the welding piece to prevent the push plate 11 from pushing two welding pieces at the same time. A limit notch 12 is provided at the end of the push plate 11. The welding piece in the hopper 3 falls into the limit notch 12. During the movement of the push plate 11, the limit notch 12 limits the welding piece.

[0019] The hopper 3 is horizontally equipped with a second telescopic rod 15 connected to the push plate 11. The second telescopic rod 15 controls the push plate 11 to move back and forth, thereby stably outputting the welding sheet in the hopper 3 from the distance between the hopper 3 and the support platform 1.

[0020] Example 2: A welding sheet conveying device includes a support platform 1, a column 2 above the support platform 1, and a hopper 3 with openings at the top and bottom on the side of the column 2. The hopper 3 is fixedly connected to the column 2 by a connecting beam. The internal shape of the hopper 3 is consistent with the shape of the welding sheet placed horizontally. The welding sheet slides vertically in the hopper 3 and does not slide horizontally under the limit of the hopper 3. The distance between the hopper 3 and the support platform 1 is 1.5 times the thickness of the welding sheet, ensuring that one welding sheet can slide out stably from the gap between the hopper 3 and the support platform 1, and two welding sheets cannot slide out from the gap between the hopper 3 and the support platform 1 at the same time.

[0021] A crossbeam 4 is rotatably mounted on the upper end of the column 2. A first telescopic rod 5 is vertically mounted on the end of the crossbeam 4. A pressure plate mechanism is mounted on the lower end of the first telescopic rod 5. The pressure plate mechanism includes a top plate 6 and a bottom plate 7. A compression spring 8 is mounted between the top plate 6 and the bottom plate 7. The upper and lower ends of the compression spring 8 are fixedly connected to the top plate 6 and the bottom plate 7, respectively. A limit tube 9 and a limit shaft 10 are mounted inside the compression spring 8. The limit tube 9 is fixedly connected to the top plate 6, and the limit shaft 10 is fixedly connected to the bottom plate 7.

[0022] The first telescopic rod 5 controls the pressure plate mechanism to press down. The first telescopic rod 5 and the pressure plate mechanism connected to the lower end press down the uppermost welding piece. The upper end of the support platform 1 is horizontally slidably equipped with a push plate 11. The lower end surface of the push plate 11 is provided with multiple mounting grooves 13. Rollers 14 are rotatably installed in each mounting groove 13. The rollers 14 make the push plate 11 slide more smoothly. The thickness of the push plate 11 plus the rollers 14 is three-quarters of the thickness of the welding piece to prevent the push plate 11 from pushing two welding pieces at the same time. The end of the push plate 11 is provided with a limiting notch 12. The welding piece in the hopper 3 falls into the limiting notch 12. During the movement of the push plate 11, the limiting notch 12 limits the welding piece.

[0023] The hopper 3 is horizontally equipped with a second telescopic rod 15 connected to the push plate 11. The second telescopic rod 15 controls the push plate 11 to move back and forth, thereby stably outputting the welding sheet in the hopper 3 from the distance between the hopper 3 and the support platform 1. Both the first telescopic rod 5 and the second telescopic rod 15 are electric telescopic rods. The upper end of the support platform 1 is equipped with a controller 16 that is connected to both the first telescopic rod 5 and the second telescopic rod 15. The upper end of the support platform 1 is equipped with a limit switch 17 corresponding to the push plate 11. The limit switch 17 is connected to the controller 16. The limit switch 17 is used to determine the number of reciprocating movements of the push plate 11 and transmit data information to the controller 16. The controller 16 controls the first telescopic rod 5 to extend and continuously press down using the pressure plate mechanism.

[0024] The working principle is as follows:

[0025] Multiple solder pads are stacked together and placed in the hopper 3. The crossbeam 4 is rotated until the pressure plate mechanism is aligned with the solder pads. The controller 16 controls the first telescopic rod 5 to extend and use the pressure plate mechanism to press down the uppermost solder pad. The second telescopic rod 15 controls the push plate 11 to move back and forth. During the back and forth movement, the solder pad at the bottom of the hopper 3 is pushed out from the bottom of the hopper 3, ensuring a continuous and stable supply of individual solder pads. As the push plate 11 moves back and forth, the limit switch 17 senses the movement of the push plate 11 and sends a signal to the controller 16 according to the frequency. The controller 16 controls the first telescopic rod 5 to gradually extend, keeping it pressed against the upper end of the solder pad, ensuring that the soldering process of the PCBN blade of the overall solder pad structure is stable and normal.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
