Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically an automatic arrangement and feeding device for screw processing. Background Technology

[0002] A screw is a mechanical component with a cylindrical shape, typically featuring helical grooves or protrusions known as threads. Screws are primarily used for transmitting power, converting motion, and as fasteners to connect and secure other components.

[0003] The screw raw materials are cylindrical and are usually piled up after cutting. Before the screws are processed, the raw materials need to be manually removed one by one and placed on a horizontal shelf. They are then picked up individually during processing, which is time-consuming and labor-intensive. In order to meet the requirements of automated processing, the screws on the horizontal shelf need to be placed at equal intervals so that the robotic arm can grab them at any time. This places higher demands on the placement of the screw raw materials, increases the time for manual handling and adjustment, and reduces processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device for screw processing, which can automatically arrange intermittent material discharge and improve processing efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automatic feeding and arranging device for screw processing includes a base plate. Support plates are fixedly connected to the front and rear sides of the top of the base plate, and a set of evenly arranged spacer blocks are fixedly connected to the top of the support plates. An arranging mechanism is provided on the top of the base plate. The arranging mechanism includes a pair of synchronously rotatable rotating rods. A driving block is fixedly connected to the front of the rotating rod. The tops of the two driving blocks are hinged together to a material plate through a hinge. A set of evenly arranged connecting blocks are fixedly connected to the top of the material plate.

[0007] As a further embodiment of this utility model: the arrangement mechanism includes an L-shaped plate fixedly connected to the front of the rear support plate, the L-shaped plate includes a horizontal plate and a vertical plate connected vertically, the horizontal plate is connected to the rear support plate, and the left and right sides of the vertical plate are respectively rotatably connected to the rotating rod.

[0008] The outer sides of the two rotating rods are fixedly connected to synchronous pulleys, and the outer sides of the two synchronous pulleys are engaged with a transmission belt.

[0009] A motor is fixedly installed on the rear side of the support plate, and the output end of the motor is fixedly connected to the corresponding rotating rod.

[0010] As a further improvement of this utility model, the top of the connecting block is provided with an arc-shaped groove that adapts to the surface shape of the screw.

[0011] As a further embodiment of this utility model: a feeding mechanism is provided on the left side of the base plate, the feeding mechanism includes a fixed platform, a material conveying box is fixedly connected to the top of the fixed platform, and a material outlet is provided on the bottom right side of the material conveying box;

[0012] The right side of the fixed platform is fixedly connected to the front and rear ends of the platform, and the right side of the inclined plate is fixedly connected to the support plate.

[0013] As a further embodiment of this utility model: the feeding box is composed of a feeding section, an inclined section and a discharging section from top to bottom. The feeding section is rectangular and open at the top. The inclined section is an isosceles trapezoid that is wider at the top and narrower at the bottom. The discharging section is a relatively narrow rectangle.

[0014] As a further improvement of this utility model, a boundary plate is fixedly connected to the top of the inclined plate.

[0015] As a further improvement of this utility model, the bottom of the discharge section is provided with a slope that slopes towards the discharge port.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model starts the motor via an external power supply. The motor's output drives the right rotating rod to rotate clockwise. Through the synchronous pulley and transmission belt, the left rotating rod rotates synchronously, causing the two driving blocks to flip at the same angle. Because the two driving blocks flip at the same angle, the material plate hinged to the driving blocks remains horizontal at all times and flips in the same direction as the driving blocks. When the driving blocks flip from bottom to top, the leftmost connecting block at the top of the driving block lifts the screw material on the left side of the support plate upwards, while the other connecting blocks lift the screw material between the corresponding two adjacent spacers. The screw material flips clockwise with the driving blocks and falls between the two adjacent spacers on the right. By controlling the speed of the motor output, it ensures that the screw material moves one spacer block to the right each time, achieving an automatic intermittent material discharge effect. This allows the screw material to be intermittently placed in the pick-up position for easy subsequent gripping and processing.

[0018] 2. This utility model discharges the screw raw material into the conveying box through the feeding section. The screw raw material accumulates inside the inclined section. Because the inclined section is an isosceles trapezoid, the screw raw material is more likely to enter the discharge section under gravity. The discharge section is narrow, so only one screw raw material can be stored horizontally or two screw raw materials can be stored vertically. Therefore, only one screw raw material can be discharged at a time. The screw raw material inside the discharge section is easily discharged from the outlet due to the gravity of the screw above. It is discharged to the left side of the two support plates through the inclined plate. Because the discharge section discharges only one at a time and the inclination of the inclined plate is small, the screws on the left side of the support plate are not easy to stack together, thus facilitating the arrangement mechanism to drive one screw raw material at a time. Furthermore, when the inclined plate surface is horizontally filled with screw material, the screw material will block the discharge port, preventing further discharge. The screw material accumulated on the far left of the support plate is carried away by the arrangement mechanism, and the screw material accumulated on the inclined plate rolls to the left by one screw length. A gap of screw material will appear between the discharge port and the inclined plate, so the screw pressure inside the lower part of the discharge section rolls outward to occupy the gap and block the discharge port again, thus achieving the effect of automatic quantitative discharge.

[0024] like Figure 1 , 2As shown, an automatic feeding device for screw processing includes a base plate 10, with support plates 11 fixedly connected to the front and rear sides of the top of the base plate 10, and a set of evenly arranged spacers 12 fixedly connected to the top of the support plates 11; and an arrangement mechanism 20 is provided on the top of the base plate 10.

[0025] refer to Figure 1 , 3 4. The arrangement mechanism 20 includes an L-shaped plate 201 fixedly connected to the front of the rear support plate 11. The L-shaped plate 201 includes a horizontal plate and a vertical plate connected vertically. The horizontal plate is connected to the rear support plate 11. The left and right sides of the vertical plate are respectively rotatably connected to a rotating rod 202 that can rotate synchronously. The front of the rotating rod 202 penetrates the surface of the vertical plate, and a driving block 203 is fixedly connected to the front of the rotating rod 202. The tops of the two driving blocks 203 are hinged together to a material plate 204 through a hinge. A set of evenly arranged connecting blocks 205 are fixedly connected to the top of the material plate 204.

[0026] Specifically, synchronous pulleys 206 are fixedly connected to the outer sides of the two rotating rods 202, and a transmission belt 207 is meshed with the outer sides of the two synchronous pulleys 206; a motor 208 is fixedly installed on the rear side of the rear support plate 11, and the output end of the motor 208 is fixedly connected to the corresponding rotating rod 202.

[0027] Preferably, the top of the connecting block 205 is provided with an arc-shaped groove adapted to the surface shape of the screw. In use, the screw material is discharged from the left side of the arrangement mechanism 20 and accumulates on the left side of the support plate 11. Then, the motor 208 is started by an external power supply. The output end of the motor 208 drives the right rotating rod 202 to rotate clockwise. Through the transmission of the synchronous pulley 206 and the transmission belt 207, the left rotating rod 202 rotates synchronously, thereby causing the two driving blocks 203 to flip at the same angle. Because the two driving blocks 203 are at the same angle... The flipping mechanism ensures that the material plate 204, hinged to the drive block 203, remains horizontal at all times and flips in the same direction as the drive block 203. When the drive block 203 flips from bottom to top, the leftmost connecting block 205 at the top of the drive block 203 lifts the screw material on the left side of the support plate 11 upwards, while other connecting blocks 205 lift the screw material between the corresponding two adjacent spacer blocks 12. The screw material flips clockwise with the drive block 203 and falls between the two adjacent spacer blocks 12 on the right. By controlling the speed of the motor 208 output, it is ensured that the screw material moves to the right by the distance of one spacer block 12 each time, achieving the effect of automatic intermittent material discharge. Furthermore, a robotic arm for gripping the screw material can be set on the right side of the arrangement mechanism 20. The robotic arm grips the screw material inside the two adjacent spacer blocks 12 on the rightmost side, facilitating subsequent processing.

[0028] refer to Figure 1 , 3 A feeding mechanism 30 is provided on the left side of the base plate 10. The feeding mechanism 30 includes a fixed platform 301. A material conveying box 302 is fixedly connected to the top of the fixed platform 301. A material outlet 303 is opened on the bottom right side of the material conveying box 302. Inclined plates 304 are fixedly connected to the front and rear ends of the right side of the fixed platform 301, respectively. The right side of the inclined plate 304 is fixedly connected to the support plate 11.

[0029] Specifically, the feeding box 302 consists of a feeding section 3021, an inclined section 3022, and a discharge section 3023 from top to bottom. The feeding section 3021 is rectangular and open at the top. The inclined section 3022 is an isosceles trapezoid that is wider at the top and narrower at the bottom. The discharge section 3023 is a relatively narrow rectangle. Preferably, the bottom of the discharge section 3023 is provided with a slope that slopes towards the discharge port 303 to facilitate the discharge of the screw raw material from the discharge port 303.

[0030] In use, the screw feed material is discharged into the feed box 302 through the feed section 3021. The screw feed material accumulates inside the inclined section 3022. Because the inclined section 3022 is an isosceles trapezoid, the screw feed material is more likely to enter the discharge section 3023 under the influence of gravity. The discharge section 3023 is narrow, so only one screw feed material can be stored horizontally and two screw feed materials can be stored vertically inside the discharge section 3023. Therefore, only one screw feed material can be discharged at a time. The screw feed material inside the discharge section 3023 is subjected to the gravity of the screw above, so it is easy to be discharged from the discharge port 303 and discharged to the left side of the two support plates 11 through the inclined plate 304. Because the discharge section 3023 discharges only one screw feed material at a time and the inclination of the inclined plate 304 is small, the screw feed material on the left side of the support plate 11 is not easy to pile up together, thus making it easier for the arrangement mechanism 20 to drive one screw feed material at a time. Furthermore, when the surface of the inclined plate 304 is horizontally filled with screw material, the screw material will block the discharge port 303, preventing the screw from continuing to discharge. After the screw material piled on the leftmost side of the support plate 11 is carried away by the arrangement mechanism 20, the screw piled on the inclined plate 304 rolls to the left a distance equal to the length of screw material. A gap of screw material will appear between the discharge port 303 and the inclined plate 304, so the screw material inside the lower part of the discharge section 3023 will roll outward under pressure and occupy the gap, blocking the discharge port 303 again, thereby achieving the effect of automatic quantitative discharge.

[0031] Preferably, a boundary plate 305 is fixedly connected to the top of the inclined plate 304; the boundary plate 305 is used to guide the screw when it rolls on the surface of the inclined plate 304.

[0032] The working principle of this utility model is as follows: The motor 208 is started by an external power supply. The output end of the motor 208 drives the right rotating rod 202 to rotate clockwise. Through the transmission of the synchronous pulley 206 and the transmission belt 207, the left rotating rod 202 rotates synchronously, thereby causing the two driving blocks 203 to flip at the same angle. Since the two driving blocks 203 flip at the same angle, the same material plate 204 hinged to the driving block 203 always remains in a horizontal state and flips in the same direction as the driving block 203 flips. When the driving block 203 flips from bottom to top, the leftmost connecting block 205 at the top of the driving block 203 will lift the screw material on the left side of the support plate 11 upward, while the other connecting blocks 205 will lift the screw material between the two adjacent spacer blocks 12. The screw material flips clockwise with the driving block 203 and falls between the two adjacent spacer blocks 12 on the right. By controlling the speed of the output end of the motor 208, the screw material moves to the right by the distance of one spacer block 12 each time, achieving the effect of automatic intermittent material discharge; and a robotic arm for gripping the screw material can be set on the right side of the arrangement mechanism 20, which can grip the screw material inside the two adjacent spacer blocks 12 on the far right, facilitating subsequent processing.
