A feeding mechanism for wire rod production

Abstract

This utility model discloses a feeding mechanism for wire production, including a base plate. The base plate is equipped with a feeding seat and a feeding drive mechanism that drives the feeding seat to move back and forth. The front end of the feeding seat is equipped with a clamping seat and a lifting drive mechanism that allows the clamping seat to have multiple working positions. The clamping seat is equipped with a terminal positioning clamp for clamping and positioning terminals on the wire and an opening drive mechanism that controls the opening and closing of the terminal positioning clamp. This utility model, by setting up a lifting drive mechanism that allows the clamping seat to have multiple working positions, enables the terminal positioning clamp to stop at multiple working positions. This allows the terminal positioning clamp to avoid the terminals when completing wire feeding and resetting, preventing the terminals from rubbing or touching each other, which could cause scratches, pull-out of the die, or loosening, thus improving production quality.

Description

Technical Field

[0001] This utility model relates to the field of wire production equipment technology, specifically to a feeding mechanism for wire production. Background Technology

[0002] Data cables, charging cables, and other similar cables are typically injection molded from conductors and terminals. Current production methods involve first soldering the wires to the terminals, then manually inserting the soldered terminals one by one into a mold strip. The mold strip is then placed in the corresponding mold position within the injection molding machine, and finally, injection molding is performed. When manually inserting the wires directly into the mold strip, due to the high degree of fit between the terminals and the sockets on the mold strip, and the small size of the terminals, less skilled workers need to spend considerable time and effort to accurately align the terminals and sockets. This results in low production efficiency and is prone to damaging the terminals due to inaccurate positioning, affecting the quality of the molded cable.

[0003] The utility model patent with publication number CN222712670U discloses a feeding mechanism for wire production. Although it can quickly and accurately push the wire onto the die, it still has the following shortcomings in actual use: Since the lifting cylinder can only make the terminal positioning clamp have two working positions, up and down, after the wire is pushed, when the terminal positioning clamp is in the upper working position, the feeding drive mechanism first drives the feeding seat to reset. At this time, although the terminal positioning clamp is in a fully open state, the terminal positioning clamp will still rub against the terminal on the wire during the reset process, which may cause the terminal to be scratched, pulled out of the die, or loosened in the die, affecting the production quality of the wire. Utility Model Content

[0004] This utility model addresses the deficiencies in existing technologies by providing a feeding mechanism for wire production, which can improve the production efficiency and quality of wire.

[0010] As a preferred technical solution, the terminal positioning seat and the positioning support seat are respectively provided with a first through groove and a second through groove for the extension arm to move in a specific direction. The extension directions of the first through grooves located on both sides of the same terminal positioning groove are parallel to each other. The floating seat is provided with a connecting groove. The extension arm passes through the first through groove and the second through groove in sequence and extends into the corresponding connecting groove. A connecting shaft passes through the side wall of the connecting groove and connects to the extension arm. During operation, the position of the connecting shaft and the floating seat remains unchanged.

[0011] As a preferred technical solution, the terminal positioning seat and the positioning support seat are respectively provided with a first through groove and a second through groove, the floating seat is provided with a connecting groove, and the extension arm passes through the first through groove and the second through groove in sequence and extends into the corresponding connecting groove.

During operation, the positions of the connecting shaft and the floating seat remain unchanged, and the positions of the guide shaft and the positioning support seat remain unchanged.

[0012] As a preferred technical solution, the guide groove has a vertical section and an inclined section that are interconnected. The vertical section is located at the upper end of the tilting section, and the tilting section is inclined from top to bottom toward the center side of the corresponding terminal positioning groove.

[0013] As a preferred technical solution, the terminal positioning seat is provided with a first through groove that allows the extension arm to move in a specific direction. Two first through grooves located on both sides of the same terminal positioning groove are arranged in an inverted V-shape. The floating seat is provided with a connecting groove. The extension arm passes through the first through groove and extends into the corresponding connecting groove. Two connecting shafts pass through the side wall of the connecting groove and are connected to the corresponding extension arm. The side wall of the connecting groove is provided with a limiting inclined groove corresponding to the two connecting shafts. The limiting inclined grooves on both sides of the same connecting groove are inclined in opposite directions, and the projections of the two limiting inclined grooves along the axial direction of the connecting shaft intersect to form an X shape. During operation, the connecting shaft can move relative to the floating seat along the limiting inclined groove.

[0014] As a preferred technical solution, the base plate is provided with a horizontally extending wire feeding guide rail, the feeding seat is slidably connected to the wire feeding guide rail via a slider, and the feeding driving mechanism is a push cylinder, which drives the feeding seat to slide back and forth along the wire feeding guide rail.

[0016] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, by setting a feeding seat that can be moved back and forth by a feeding drive mechanism, and setting a terminal positioning clamp and a clamping drive mechanism at the front end of the feeding seat, the terminals on the wire can be pre-clamped and positioned by the terminal positioning clamp, and then the feeding drive mechanism inserts the wire into the corresponding mold strip insertion hole. This eliminates the need for manual insertion of the terminals into the mold strip insertion hole, thereby improving the efficiency and production quality of wire injection molding. By setting a lifting drive mechanism that allows the clamping seat to have multiple working positions, the feeding drive mechanism can drive the feeding seat to reset when the clamping seat is in the middle working position. At this time, the terminals of the wire are suspended in the terminal positioning clamp, so that the terminal positioning clamp can avoid the terminals when resetting, avoiding friction or contact between the terminals and the terminal positioning clamp, which could cause scratches on the terminals or pull the terminals out of the mold strip and become loose, thus improving production quality.

[0049] like Figure 1-7 As shown, an embodiment of the present invention provides a wire feeding mechanism, including a base plate 10. The base plate 10 is provided with a feeding seat 20 and a feeding drive mechanism for driving the feeding seat 20 to move back and forth. The front end of the feeding seat 20 is provided with a clamping seat 30 and a lifting drive mechanism for giving the clamping seat 30 multiple working positions. The clamping seat 30 is provided with a terminal positioning clamp 40 for clamping and positioning terminals on the wire and an opening and closing drive mechanism for controlling the opening and closing of the terminal positioning clamp 40. The device includes a terminal positioning seat 41 fixed to the upper end of the clamping base 30. The terminal positioning seat 41 has multiple terminal positioning slots 411 distributed along its length at its upper end. Each terminal positioning slot 411 has positioning clamping blocks 42 on both sides. Each positioning clamping block 42 has a downwardly extending extension arm 421. A floating seat 43 is provided below the terminal positioning seat 41. The extension arm 421 is connected to the floating seat 43. The clamping base 30 has a reset mechanism that ensures the floating seat 43 always has a downward tendency to move. In this embodiment, the feeding drive mechanism is a push cylinder 12. The base plate 10 has a horizontally extending wire feeding guide rail 11. The feeding seat 20 is slidably connected to the wire feeding guide rail 11 via a slider. The push cylinder 12 drives the feeding seat 20 to slide back and forth along the wire feeding guide rail 11. It should be understood that the feeding drive mechanism can also be replaced by an electric cylinder, motor, or lead screw combination.

[0050] In this invention, the front end of the base plate 10 is provided with a mold strip positioning seat 50, the mold strip positioning seat 50 is provided with a mold strip positioning groove 51, the base plate 10 is also provided with a wire clamp opening assembly, the rear end of the base plate 10 is provided with an opening support seat 60, the upper surface of the opening support seat 60 is provided with a horizontally extending wire clamp opening guide rail, the wire clamp opening assembly includes an opening slide 61 and a wire clamp opening cylinder 62 that drives the opening slide 61 to slide along the wire clamp opening guide rail, the front end of the opening slide 61 is provided with a plurality of forward-extending push rods 63, and the feeding seat 20 is movably disposed between the opening support seat 60 and the mold strip positioning seat 50. In this embodiment, the opening support seat 60 is arranged in an inverted U-shape, thereby forming an installation position for installing the push cylinder 12 below the opening support seat 60.

[0051] Specifically, a positioning support 44 is fixedly provided at the upper end of the clamping seat 30, and the terminal positioning seat 41 is fixedly installed on the front side of the upper end of the positioning support 44. Multiple wire clearance grooves 441 are provided on the rear side of the upper end of the positioning support 44, and each wire clearance groove 441 corresponds one-to-one with a terminal positioning groove 411. The positioning support 44 is provided with a downwardly extending guide rod 45, and the floating seat 43 is slidably connected to the guide rod 45. In this embodiment, the reset mechanism is a compression spring (not shown) located between the terminal positioning seat 41 and the floating seat 43. It should be understood that in actual use, a tension spring or other elastic element can also be used instead of the reset mechanism.

[0052] Specifically, the lifting drive mechanism includes a first lifting cylinder 21 and a second lifting cylinder 22. The front end of the feeding seat 20 is provided with a vertically extending lifting guide rail 23. The clamping seat 30 is slidably connected to the lifting guide rail 23 via a slider. The driving end of the first lifting cylinder 21 extends upward and connects to the second lifting cylinder 22, and the driving end of the second lifting cylinder 22 extends upward and connects to the clamping seat 30. In this embodiment, through the cooperation of the first lifting cylinder 21 and the second lifting cylinder 22, the terminal positioning clamp 40 can have multiple working positions (upper, middle, and lower). It should be understood that in actual use, the lifting drive mechanism can also be replaced by an electric cylinder or a servo motor with a lead screw drive.

[0053] The clamping drive mechanism includes a pre-opening cylinder 31 and a fully opening cylinder 32 for pushing the floating seat 43 upward. The pre-opening cylinder 31 enables the terminal positioning clamp 40 to be in a slightly open state, and the fully opening cylinder 32 enables the terminal positioning clamp 40 to be in a fully open state. In this utility model, there are two pre-opening cylinders 31 and one fully opening cylinder 32. The two pre-opening cylinders 31 are symmetrically arranged on the left and right sides of the fully opening cylinder 32. The driving ends of both the pre-opening cylinder 31 and the fully opening cylinder 32 extend upward. The output end of the fully opening cylinder 32 is provided with a drive plate 33. The drive plate 33 is provided with two abutment parts, which are distributed along the length direction of the floating seat 43. It should be noted that in actual use, the number and position of the pre-opening cylinder and the fully opening cylinder can also be set as needed.

[0054] Specifically, in this embodiment, the terminal positioning seat 41 and the positioning support seat 44 are respectively provided with a first through groove 412 and a second through groove 442 for the extension arm 421 to move in a specific direction. The extension directions of the first through grooves 412 located on both sides of the same terminal positioning groove 411 are parallel to each other. The floating seat 43 is provided with a connecting groove 431. The extension arm 421 passes through the first through groove 412 and the second through groove 442 in sequence and extends into the corresponding connecting groove 431. A connecting shaft 46 passes through the side wall of the connecting groove 431 and connects to the extension arm 421. During operation, the position of the connecting shaft 46 and the floating seat 43 remains unchanged. In this embodiment, both the first through slot 412 and the second through slot 442 extend vertically in a direction perpendicular to the horizontal plane, and their sizes are adapted to the extension arm 421, so that the extension arm 421 can move up and down along the first through slot 412 and the second through slot 442 under the drive of the floating seat 43. When the driving ends of the pre-opening cylinder 31 and the fully open cylinder 32 retract, the floating seat 43 pulls down the extension arm 421 under the action of the reset mechanism, so that the positioning clamp 42 clamps and positions the terminal in the terminal positioning groove 411. When the driving end of the pre-opening cylinder 31 pushes the floating seat 43 upward, the floating seat 43 makes the positioning clamp 42 move upward away from the terminal positioning groove 411, at which time it is in a half-open clamping state. When the driving end of the fully open cylinder 32 pushes the floating seat 43 upward, the floating seat 43 makes the positioning clamp 42 in a fully open clamping state.

[0055] like Figure 8-10In another embodiment of this utility model, the difference from the above embodiment is that the terminal positioning seat 41 and the support seat 60 are respectively provided with a first through groove 412 and a second through groove 442, the floating seat 43 is provided with a connecting groove 431, and the extension arm 421 passes through the first through groove 412 and the second through groove 442 in sequence and extends into the corresponding connecting groove 431. The extension arm 421 is provided with a through guide groove 422. The guide grooves 422 on the extension arms 421 located on both sides of the same terminal positioning groove 411 are arranged in an inverted V-shape. During assembly, a connecting shaft 46 passes through the side wall of the connecting groove 431 and is rotatably connected to the extension arm 421. A guide shaft 47 passes through the side wall of the second through groove 442 and the guide groove 422 and is connected to the extension arm 421. During operation, the positions of the connecting shaft 46 and the floating seat 43 remain unchanged, and the positions of the guide shaft 47 and the positioning support seat 44 remain unchanged. In this embodiment, the guide groove 422 has a vertical section and an inclined section that are interconnected. The vertical section is located at the upper end of the tilting section. The tilting section is inclined from top to bottom toward the center side of the corresponding terminal positioning groove 411. The width of the first through groove 412 and the second through groove 442 is greater than the width of the extension arm 421. Thus, when the floating seat 43 drives the extension arm 421 to move, the two extension arms 421 located on both sides of the same terminal positioning groove 411 can open and close with the cooperation of the guide shaft 47 and the guide groove 422. By setting the guide groove 422 as a vertical section and an inclined section, the positioning clamp 42 opens upward first in the direction away from the terminal positioning groove 411 when it opens, and then opens upward in the vertical direction.

[0056] like Figure 11-12As shown, another embodiment of this utility model differs from the above embodiment in that the terminal positioning seat 41 is provided with a first through groove 412 that allows the extension arm 421 to move in a specific direction. Two first through grooves 412 located on both sides of the same terminal positioning groove 411 are arranged in an inverted V-shape. The positioning support seat 44 has a clearance groove 443 for the extension arm to pass through. A connecting seat 48 is fixedly provided at the upper end of the floating seat 43. The connecting seat 48 has a connecting groove 431 through which the extension arm 421 passes. 412 and the clearance groove 443 extend into the corresponding connecting groove 431. The two connecting shafts 46 pass through the side wall of the connecting groove 431 and are connected to the corresponding extension arm 421. The side wall of the connecting groove 431 is provided with limiting grooves 432 corresponding to the two connecting shafts 46. The limiting grooves 432 on both sides of the same connecting groove 431 are inclined in opposite directions, and the projections of the two limiting grooves 432 along the axial direction of the connecting shaft 46 intersect in an X shape. During operation, the connecting shaft 46 can move relative to the floating seat 43 along the limiting groove 432. In this embodiment, in the clamping state, the floating seat 43 pulls the positioning clamp 42 downward under the action of the reset mechanism. At this time, the connecting shaft 46 on the extension arm 421 moves to the highest point of the limiting groove 432. In the fully open state, when the output end of the fully open cylinder 32 pushes the floating seat 43 upward, the floating seat 43 drives the extension arm 421 to the highest point. At this time, the connecting shaft 46 on the extension arm 421 is located at the lowest point of the limiting groove 432, and the positioning clamp 42 is fully open.

[0057] like Figure 13-14As shown, this utility model is installed on a workbench 100 during use. A movable turntable 110 is located in the center of the workbench 100. An injection molding mechanism (not shown) is also provided on the workbench 100 around the turntable 110. A material frame 120 rotates with the turntable 110. A mold strip 130 and a wire clamp 140 are provided on the material frame 120. During material loading, the turntable 110 moves the material frame 120 above the loading mechanism of this application. Then, the turntable 110 moves downwards, causing the mold strip 130 on the material frame 120 to fall into the mold strip positioning position. Inside the slot 51, the wire clamp 140 on the material frame 120 is simultaneously positioned between the opening slide 61 and the clamping seat 30. Then, the first lifting cylinder 21 and the second lifting cylinder 22 control the clamping seat 30 to move upwards, so that the height of the terminal positioning slot 411 matches the height of the insertion hole on the mold strip 130. Next, the pre-opening cylinder 31 makes the terminal positioning clamp 40 half-open. Driven by the wire clamp opening cylinder 62, the push rod 63 of the wire clamp opening assembly is inserted between the two clamping plates of the wire clamp 140, opening the wire clamp 140. At this time, the wire end is manually removed. The terminal is inserted into the terminal positioning clamp 40, with the front end of the terminal extending forward beyond the clamp 40. Simultaneously, the wire body is placed into the wire clamp 140. After the wire is clamped, the wire clamp opening cylinder 62, the pre-opening cylinder 31, and the wire clamp opening cylinder 62 retract to reset. The terminal positioning clamp 40 clamps and positions the terminal. Next, the push cylinder 12 controls the feed seat 20 to push towards the mold strip 130. The terminal positioning clamp 40 on the feed seat 20 inserts the wire terminal into the insertion hole of the mold strip 130. After pushing to the correct position, the fully open cylinder 32 positions the terminal. When clamp 40 is fully opened, the second lifting cylinder 22 retracts and resets, suspending the terminal on the wire inside the terminal positioning clamp 40. Then, the push cylinder 12 retracts and resets, causing the terminal positioning clamp 40 to move horizontally relative to the terminal. Then, the first lifting cylinder 21 retracts and resets, causing the wire body to move upward from the opening of the terminal positioning clamp 40 and out of the terminal positioning clamp 40. Finally, the turntable 110 moves upward to remove the wire from the feeding mechanism. Then, the material frame 120 containing the wire is moved into the injection mold by rotating the turntable 110, thus completing the positioning and feeding of the wire.

[0058] In summary, this utility model, by setting a feeding seat that can be moved back and forth by a feeding drive mechanism, and setting a terminal positioning clamp and a clamping drive mechanism at the front end of the feeding seat, allows the terminals on the wire to be pre-clamped and positioned by the terminal positioning clamp, and then the feeding drive mechanism inserts the wire into the corresponding insertion hole of the mold strip. This eliminates the need for manual insertion of the terminals into the insertion hole of the mold strip, thereby improving the efficiency and production quality of wire injection molding. At the same time, by setting a lifting drive mechanism that allows the clamping seat to have multiple working positions, the feeding drive mechanism can drive the feeding seat to reset when the clamping seat is in the middle working position. At this time, the terminals of the wire are suspended in the terminal positioning clamp, thereby avoiding the terminals from rubbing or touching each other with the terminal positioning clamp, which could cause the terminals to be scratched or pulled out of the mold strip or become loose, thus improving production quality.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
