Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically a high-efficiency feeding device and feeding method for screwdriver bit processing. Background Technology

[0002] Screwdriver bits are tools mounted on screwdrivers, electric screwdrivers, and other similar implements to tighten or loosen screws. Forming the tip is a crucial step in the manufacturing process. Under current technology, one pressing operation corresponds to the formation of one screwdriver bit, which doesn't limit the overall processing efficiency. The problem limiting efficiency lies in the feeding process before placing the raw material in the processing position. Currently, feeding is primarily done manually. Even with the introduction of some automation, such as using cylinders to push the material to the processing position, it's only one part of the entire feeding process, offering limited improvement in overall feeding efficiency. Therefore, improving the overall feeding efficiency of the process before screwdriver bit tip forming has become an urgent problem for relevant technicians. Summary of the Invention

A first detection hole is vertically provided through the right end of the horizontal guide groove, and the second sensor is located directly below the first detection hole.

[0008] Furthermore, the right side of the inside of the turntable is provided with short holes in a circular array, and the right side of the outside of the turntable is provided with long holes in a circular array. The short holes and the long holes are connected. The long holes correspond one-to-one with the four segments of the straight groove extending from the center of the turntable. Each long hole corresponds to two short holes. A second detection hole is horizontally provided through the edge of the turntable and at the middle position between adjacent long holes. A third sensor and a fourth sensor are fixedly provided on the upper right side of the right plate. There are two third sensors, and each of the two third sensors corresponds one-to-one with the two short holes corresponding to each long hole.

[0009] Furthermore, a second slide rail is fixedly installed behind the turntable, a second slider is slidably installed on the upper part of the second slide rail, a second cylinder is fixedly installed on the upper part of the second slider, and a first positioning bolt is installed on one side of the second slider.

[0011] Furthermore, second positioning bolts are provided on the upper part of the base, in front of, behind and to the right of the second locator, and limiting posts are symmetrically fixed on the upper part of the base, in front of and behind the second locator.

[0012] Furthermore, a feeding method for a high-efficiency feeding device for screwdriver bit processing is as follows: (1) Pour the raw materials directly into the raw material box and stack them neatly as much as possible. Under the action of the inclined plate, the raw materials on the far right of the raw material box are located above the rear moving plate and in contact with the rear fixed plate. Start the first cylinder, the second cylinder, the third cylinder, the fourth cylinder, the linear stepper motor, and the drive motor. (2) The output end of the first cylinder pushes the lifting plate, the rear moving plate, the middle moving plate and the front moving plate to move up synchronously as a whole, thereby pulling the whole to reset. When the whole is at the lower end of the stroke, the upper end of the rear moving plate is connected to the lower end of the inclined plate. When the whole is at the upper end of the stroke, the upper end of the front moving plate is connected to the upper end of the front fixed plate. In this way, the raw material above the rear moving plate can be conveyed upward step by step, and finally enters the horizontal guide trough through the front fixed plate and the transition plate in sequence. (3) The output end of the second cylinder pushes the limit rod into the straight groove opening at the last end of the turntable to a certain depth. The output shaft of the linear stepper motor pushes the moving table and the first slider to move backward along the first slide rail. The push rod pushes the raw material into the turntable through the horizontal guide groove and the straight groove opening at the front end in sequence. When the raw material touches the limit rod, the linear stepper motor stops. The output end of the second cylinder pulls the limit rod out of the turntable. During this process, the raw material passes above the first detection hole, causing the first detection hole to go through the process of "unobstructed - obstructed by the raw material - unobstructed". The second sensor detects this process and determines whether the linear stepper motor needs to stop. After the raw material inside the guide groove is pushed into the turntable one by one, the first detection hole is continuously obstructed by the push rod. The output shaft of the linear stepper motor moves forward until the first sensor detects that the first baffle is in the middle position. (4) The output end of the third cylinder pushes the second baffle to the right of the first positioner. When both sets of third sensors detect that the corresponding position of the short hole is blocked by the raw material, it indicates that the raw material has been positioned in the turntable. The drive motor drives the turntable to rotate through the reducer. When the fourth sensor detects the next second detection hole, the drive motor stops. The raw material that was pushed into the turntable in the previous step rotates from a horizontal state to a vertical state and moves down along the straight groove and the vertical guide groove in turn, finally landing vertically between the second baffle and the first positioner. (5) The output end of the fourth cylinder pushes the moving frame, push plate, and third slider as a whole to move to the right along the third slide rail. When the pneumatic finger moves above the first positioner, it stops. The pneumatic finger clamps the material at the position of the first positioner. The output end of the third cylinder pulls the second baffle forward to release the second baffle from limiting the material. The output end of the fourth cylinder continues to push the moving frame to the right. When the pneumatic finger moves above the second positioner, it stops again. The pneumatic finger opens, and the material falls directly into the positioning hole in the middle position of the second positioner. The output end of the fourth cylinder drives the moving frame to the left until it is reset. (6) The forming mold moves down and the limiting post slides into the forming mold to keep the forming mold moving vertically down until the lower surface of the forming mold contacts the upper surface of the second positioning bolt. At this time, the raw material to be processed is located inside the forming mold. The forming mold presses the raw material to be processed into shape. Then the forming mold moves up until it is reset. The staff can then take away the formed raw material. (7) The lifting and lowering of the lifting plate, the pushing of the push rod, the rotation of the turntable, the movement of the second baffle, the movement of the moving frame, and the clamping and opening of the pneumatic fingers are kept in rhythm so that each raw material can be carried out in sequence, thus maintaining efficient conveying of the raw materials.

[0013] The beneficial effects of the efficient feeding device and feeding method for screwdriver bit processing of the present invention are as follows: 1. The rear moving plate, middle moving plate, and front moving plate effectively ensure the efficient and stable upward conveying of multiple raw materials. The first feeding section effectively ensures the efficient and stable conveying of raw materials to the transfer section. The transfer section effectively ensures the efficient conversion of raw materials from horizontal to vertical. The second feeding section effectively ensures the efficient and stable conveying of raw materials to the positioning section. Compared with the traditional manual feeding and single-stage automated feeding design, this effectively improves the overall feeding efficiency of the feeding process before the screwdriver bit tip is formed. 2. The first sensor, second sensor, third sensor, and limit rod effectively ensure the feeding accuracy of the first feeding part, and the fourth sensor effectively ensures the rotation accuracy of the turntable, thereby effectively ensuring the feeding accuracy. Combined with the positioning of the second positioning bolt at the lower end of the forming mold and the sliding limit of the limit post during the lowering process of the forming mold, the forming mold is accurately positioned, thus effectively ensuring the final forming accuracy of the screwdriver bit.

[0026] Furthermore, a feeding method for a high-efficiency feeding device for screwdriver bit processing is as follows: (1) Pour the raw materials directly into the raw material box 1 and stack them neatly as much as possible. Under the action of the inclined plate 10, the raw materials on the far right of the raw material box 1 are located above the rear moving plate 17 and in contact with the rear fixed plate 8. Start the first cylinder 19, the second cylinder 33, the third cylinder 39, the fourth cylinder 53, the linear stepper motor 21, and the drive motor 46. (2) The output end of the first cylinder 19 pushes the lifting plate 18, the rear moving plate 17, the middle moving plate 16, and the front moving plate 15 to move upward as a whole, thereby pulling the whole to reset. When the whole is at the lower end of the stroke, the upper end of the rear moving plate 17 is connected to the lower end of the inclined plate 10. When the whole is at the upper end of the stroke, the upper end of the front moving plate 15 is connected to the upper end of the front fixed plate 9. In this way, the raw material above the rear moving plate 17 can be conveyed upward step by step, and finally enters the horizontal guide trough 24 through the front fixed plate 9 and the transition plate 13 in sequence. (3) The output end of the second cylinder 33 pushes the limit rod 42 into the opening of the straight groove 48 at the rear end of the turntable 35 to a certain depth. The output shaft of the linear stepper motor 21 pushes the moving table 14 and the first slider 29 to move backward along the first slide rail 23. The push rod 22 pushes the raw material into the turntable 35 through the horizontal guide groove 24 and the opening of the straight groove 48 at the front end. When the raw material touches the limit rod 42, the linear stepper motor 21 stops. The output end of the second cylinder 33 pulls the limit rod 42 out of the turntable 35. During this process, the raw material passes above the first detection hole 28, so that the first detection hole 28 goes through the process of "unobstructed - blocked by raw material - unobstructed". The second sensor detects this process and determines whether the linear stepper motor 21 needs to stop. After the raw material inside the guide groove is pushed into the turntable 35 one by one, the first detection hole 28 is continuously blocked by the push rod 22. The output shaft of the linear stepper motor 21 moves forward until the first sensor 26 detects that the first baffle 25 is in the middle position. (4) When the output end of the third cylinder 39 pushes the second baffle 40 to the right of the first positioner 38, when both sets of third sensors 30 detect that the corresponding position of the short hole 49 is blocked by the raw material, it indicates that the raw material has been positioned in the turntable 35. The drive motor 46 drives the turntable 35 to rotate through the reducer 47. When the fourth sensor 34 detects the next second detection hole, the drive motor 46 stops. The raw material that was pushed into the turntable 35 in the previous step rotates from a horizontal state to a vertical state and moves down along the straight groove 48 and the vertical guide groove 41 in turn, and finally falls vertically between the second baffle 40 and the first positioner 38. (5) The output end of the fourth cylinder 53 pushes the moving frame 56, the push plate 55, and the third slider 51 as a whole to move to the right along the third slide rail 52. When the pneumatic finger 60 moves above the first positioner 38, it stops. The pneumatic finger 60 clamps the material at the position of the first positioner 38. The output end of the third cylinder 39 pulls the second baffle 40 forward to release the second baffle 40 from limiting the material. The output end of the fourth cylinder 53 continues to push the moving frame 56 to the right. When the pneumatic finger 60 moves above the second positioner 59, it stops again. The pneumatic finger 60 opens, and the material falls directly into the positioning hole in the middle position of the second positioner 59. The output end of the fourth cylinder 53 drives the moving frame 56 to the left until it is reset. (6) The forming mold 4 moves down, and the limiting post 57 slides into the forming mold 4 so that the forming mold 4 moves vertically down until the lower surface of the forming mold 4 contacts the upper surface of the second positioning bolt 58. At this time, the raw material to be processed is located inside the forming mold 4. The forming mold 4 presses the raw material to be processed into shape. Then the forming mold 4 moves up until it is reset. The staff can then take away the formed raw material. (7) The lifting and lowering of the lifting plate 18, the pushing of the push rod 22, the rotation of the turntable 35, the movement of the second baffle 40, the movement of the moving frame 56, and the clamping and opening of the pneumatic finger 60 are kept in rhythm so that each raw material can be carried out in sequence, thus maintaining efficient conveying of the raw material.

[0027] The working principle of the high-efficiency feeding device and feeding method for screwdriver bit processing of the present invention is as follows: After starting the device, the operator only needs to pour the raw material in step (1) and take away the formed raw material in step (6). Steps (2)-(7) can run automatically to achieve high-efficiency feeding of screwdriver bit raw material, and on this basis, ensure the final forming accuracy of screwdriver bit.

[0028] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.

Limiting posts are symmetrically fixed on the upper part of the base, in front of the second locator, and behind the second locator.

9. A high-efficiency feeding device for screwdriver bit processing according to claim 8, characterized in that, The feeding method is as follows: (1) Pour the raw materials directly into the raw material box and stack them neatly as much as possible. Under the action of the inclined plate, the raw materials on the far right of the raw material box are located above the rear moving plate and in contact with the rear fixed plate. Start the first cylinder, the second cylinder, the third cylinder, the fourth cylinder, the linear stepper motor, and the drive motor. (2) The output end of the first cylinder pushes the lifting plate, the rear moving plate, the middle moving plate and the front moving plate to move up synchronously as a whole, thereby pulling the whole to reset. When the whole is at the lower end of the stroke, the upper end of the rear moving plate is connected to the lower end of the inclined plate. When the whole is at the upper end of the stroke, the upper end of the front moving plate is connected to the upper end of the front fixed plate. In this way, the raw material above the rear moving plate can be conveyed upward step by step, and finally enters the horizontal guide trough through the front fixed plate and the transition plate in sequence. (3) The output end of the second cylinder pushes the limit rod into the straight groove opening at the last end of the turntable to a certain depth. The output shaft of the linear stepper motor pushes the moving table and the first slider to move backward along the first slide rail. The push rod pushes the raw material into the turntable through the horizontal guide groove and the straight groove opening at the front end in sequence. When the raw material touches the limit rod, the linear stepper motor stops. The output end of the second cylinder pulls the limit rod out of the turntable. During this process, the raw material passes above the first detection hole, causing the first detection hole to go through the process of "unobstructed - obstructed by raw material - unobstructed". The second sensor detects this process and determines whether the linear stepper motor needs to stop. After the raw material inside the guide groove is pushed into the turntable one by one, the first detection hole is continuously obstructed by the push rod. The output shaft of the linear stepper motor moves forward until the first sensor detects that the first baffle is in the middle position. (4) The output end of the third cylinder pushes the second baffle to the right of the first positioner. When both sets of third sensors detect that the corresponding position of the short hole is blocked by the raw material, it indicates that the raw material has been positioned in the turntable. The drive motor drives the turntable to rotate through the reducer. When the fourth sensor detects the next second detection hole, the drive motor stops. The raw material that was pushed into the turntable in the previous step rotates from a horizontal state to a vertical state and moves down along the straight groove and the vertical guide groove in turn, finally landing vertically between the second baffle and the first positioner. (5) The output end of the fourth cylinder pushes the moving frame, push plate, and third slider as a whole to move to the right along the third slide rail. When the pneumatic finger moves above the first positioner, it stops. The pneumatic finger clamps the material at the position of the first positioner. The output end of the third cylinder pulls the second baffle forward to release the second baffle from limiting the material. The output end of the fourth cylinder continues to push the moving frame to the right. When the pneumatic finger moves above the second positioner, it stops again. The pneumatic finger opens, and the material falls directly into the positioning hole in the middle position of the second positioner. The output end of the fourth cylinder drives the moving frame to the left until it is reset. (6) The forming mold moves down and the limiting post slides into the forming mold to keep the forming mold moving vertically down until the lower surface of the forming mold contacts the upper surface of the second positioning bolt. At this time, the raw material to be processed is located inside the forming mold. The forming mold presses the raw material to be processed into shape. Then the forming mold moves up until it is reset. The staff can then take away the formed raw material. (7) The lifting and lowering of the lifting plate, the pushing of the push rod, the rotation of the turntable, the movement of the second baffle, the movement of the moving frame, and the clamping and opening of the pneumatic fingers are kept in rhythm so that each raw material can be carried out in sequence, thus maintaining efficient conveying of the raw materials.
