Description

Technical Field

[0001] This utility model belongs to the technical field of pin row processing, and in particular relates to a single-row pin row dividing machine. Background Technology

[0002] Pin headers are a type of connector widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Their function is to act as a bridge between blocked or isolated circuits, facilitating current or signal transmission. They are typically used with female headers to form board-to-board connections, or with electronic wire harness terminals to form board-to-wire connections; they can also be used independently for board-to-board connections. After production, pin headers need to be segmented according to requirements. Current technology typically uses manual segmentation to cut pin headers by length, which is inefficient. Therefore, the automatic pin header segmentation device disclosed in patent number 202323302462.2 was developed. However, this structure can only cut one length of pin header at a time, resulting in poor applicability. Furthermore, while this structure is primarily designed for large-volume pin header cutting to improve efficiency, for small-volume pin header cutting, the structure, which includes alignment equipment, a conveyor, a frame, a cutting device, a sorting table, and a controller, is relatively bulky and overkill, making it inconvenient to store, move, or even carry. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a single-row pin divider, which solves the problem that existing automatic pin divider equipment can only cut pins of one length type at a time during the cutting process, resulting in poor applicability. At the same time, this structure is mainly aimed at cutting large batches of pins and can improve work efficiency. However, for cutting small quantities of pins, this structure has the problem of being relatively bulky and inconvenient to store, move, or even carry.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a single-row pin divider, comprising a platform with a pull-out storage box at its front end. A material discharge port communicating with the storage box is provided on the platform. A cutting motor is mounted on the platform, and its output shaft is connected to a rotating shaft located directly above the material discharge port. One or more saw blades are spaced apart on the rotating shaft. A pushing mechanism is provided on the platform relative to the front end of the material discharge port, capable of pushing the single-row pins under the saw blades. The pushing mechanism includes an initial baffle, a termination baffle, a guide plate, a pushing frame, and a pin pusher plate. The initial baffle restricts the initial position of the pushing frame, and the termination baffle restricts the movement distance of the pushing frame. The guide plate is fixed between the initial baffle and the final baffle. A sliding block is fixed at the bottom of the pusher frame and is slidably connected to the guide plate. The pin pusher plate is slidably connected above the pusher frame. A limiting notch for limiting a single row of pins is provided at the bottom of the side of the pin pusher plate near the saw blade. An inlet is provided on the side of the limiting notch. A notch groove is provided on the side of the pusher frame near the saw blade. A pin fixing plate is fixed on the notch groove. The pin fixing plate is used to close the limiting notch in the initial state. When the pin pusher plate slides, it can push out the single row of pins on the pin fixing plate and send them into the dropping port. One or more cutting holes are symmetrically provided on the pin fixing plate and the pin pusher plate.

[0006] Preferably, in order to limit the position of the pusher frame and ensure that after cutting, the movement position of the pusher frame is just enough to push the cut single row of pins out from the pin fixing plate and into the discharge port for collection, a sliding plate is provided inside the pusher frame. The sliding plate is fixed to the pin pusher plate by locking screws, and a limiting plate is provided inside the pusher frame to limit the movement distance of the sliding plate.

[0007] Preferably, to facilitate feeding, the side of the feeding mechanism is provided with an arrangement channel that overlaps and connects with the feed inlet when the feeding frame is in the initial state.

[0008] Preferably, to improve safety, the platform is covered with a protective cover, and the front end of the protective cover is provided with an obstacle passage to facilitate the material pushing mechanism.

[0009] Preferably, to further improve safety, the rear of the protective cover is hinged to the platform, and the platform is equipped with a safety switch that controls the cutting motor to be powered when the protective cover is closed and controls the cutting motor to be powered off when the protective cover is opened.

[0010] Preferably, to facilitate the disassembly of the cutting motor later, a U-shaped seat is fixed on the side of the platform away from the material discharge port. A clamping seat is fixed on each side of the U-shaped seat by a fixing screw. The clamping seat is "Ω" shaped. The clamping seat and the U-shaped seat cooperate to form a clamp for clamping the cutting motor. A guide seat is provided on the platform near the material discharge port. The guide seat is provided with a guide hole to facilitate the passage of the output shaft of the cutting motor.

[0011] Preferably, to ensure stability, a mounting base is provided on the side of the platform away from the U-shaped base, and a hinge seat is provided on the mounting base. The hinge seat is provided with a shaft hole, and the other end of the rotating shaft is rotatably inserted into the shaft hole.

[0012] Preferably, an operating handle is provided on the storage box for ease of operation.

[0013] Preferably, to facilitate hand gripping of the shelf later, handle slots are provided on both the left and right sides of the shelf.

[0014] The present invention has the following advantages: This structure can quickly cut a small batch of single-row needles, and can cut needles of different specifications in one cut. Compared with manual single-cutting, it is more efficient. At the same time, compared with the existing automatic needle cutting equipment, the overall size of this structure is small and easy to store and carry. Moreover, it is more practical and reasonable for cutting a small number of needles, and it does not waste the potential of the material. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1

[0029] Please see Figure 1-7 As shown, it should be noted that this embodiment is for ease of viewing. Figure 1The example only shows a form with two saw blades 6. In specific embodiments, different numbers of saw blades 6 can be set according to requirements. This embodiment discloses a single-row needle cutting machine, including a platform 1. The front end of the platform 1 is connected to a storage box 2 by a pull-out mechanism. The platform 1 is provided with a material discharge port 3 communicating with the storage box 2. A cutting motor 4 is provided on the platform 1. The output shaft of the cutting motor 4 is connected to a rotating shaft 5. The rotating shaft 5 is located directly above the material discharge port 3. One or more saw blades 6 are arranged at intervals on the rotating shaft 5 (and how the saw blades 6 are installed on the rotating shaft 5, and how the distance is achieved...). Adjustable spacing is a conventional technology in this field. For reference, see the structure of a multi-blade saw with adjustable saw blade spacing disclosed in patent application number 201320164577.7. The platform 1 has a pushing mechanism 7 positioned relative to the front end of the discharge port 3, capable of pushing a single row of pins 8 under the saw blade 6. The pushing mechanism 7 includes an initial baffle 9, a termination baffle 10, a guide plate 11, a pushing frame 13, and a pin pusher plate 14. The initial baffle 9 restricts the initial position of the pushing frame 13, the termination baffle 10 restricts the movement distance of the pushing frame 13, and the guide plate 11 is fixed to the initial baffle. 9. Between the termination baffles 10, a sliding block 12 is fixed to the bottom of the pusher frame 13, and the sliding block 12 is slidably connected to the guide plate 11. The pin pusher plate 14 is slidably connected above the pusher frame 13. The bottom of the pin pusher plate 14 near the saw blade 6 is provided with a limiting notch 16 for limiting the single row of pins 8. An inlet 17 is provided on the side of the limiting notch 16. The pusher frame 13 near the saw blade 6 is provided with a notch groove 18. A pin fixing plate 15 is fixed on the notch groove 18. The pin fixing plate 15 is used to close the limiting notch 16 in the initial state. When the pin pusher plate 14 slides, it can push out the single row of pins 8 on the pin fixing plate 15 and send them into the material discharge port 3. The pin fixing plate 15 and the pin pusher plate 14 are symmetrically provided with one or more cutting holes 35. In this embodiment, it should be noted that the spacing of each cutting hole 35 can be set according to the final cutting requirements of the single row of pins 8. It is only necessary to ensure that when the corresponding saw blade 6 is inserted into the cutting hole 35, the single row of pins 8 can be cut to achieve the corresponding pin specifications. How to set the spacing of the cutting holes 35 and how to distribute them are conventional technologies in the field, so they will not be described in detail.

[0030] Preferably, in order to limit the position of the pusher 13 and ensure that after cutting, the movement position of the pusher 13 is such that the cut single row of pins 8 is pushed out from the pin fixing plate 15 and falls into the discharge port 3 for collection, a sliding plate 19 is provided inside the pusher 13. The sliding plate 19 is fixed to the pin pusher plate 14 by locking screws 20. A limiting plate 21 is provided inside the pusher 13 to limit the movement distance of the sliding plate 19. The above structure achieves the function of limiting the movement position of the sliding plate 19 by setting the limiting plate 21.

[0031] Preferably, for convenient feeding, the pushing mechanism 7 is provided with an arrangement channel 22 on its side, which overlaps and communicates with the feed inlet 17 when the pushing frame 13 is in its initial state. By setting the arrangement channel 22, during operation, a single row of needles 8 is held and inserted from one side of the arrangement channel 22. Simultaneously, another single row of needles 8 is inserted into the arrangement channel 22, and the single row of needles 8 already in the arrangement channel 22 is moved through the feed inlet 17 into the limiting notch 16. The end of the limiting notch 16 away from the feed inlet 17 then moves the single row of needles 8. The moving position is limited to place the entire single row of pins 8 into the limiting notch 16. At this time, by pushing the pusher 13 close to the saw blade 6, until the pusher 13 is limited by the stop baffle 10 and cannot move forward, the saw blade 6 can be stuck in the corresponding cutting opening 35. As the saw blade 6 rotates, the single row of pins 8 is cut. After the cutting is completed, the pin pusher plate 14 is pushed to push the cut pins out of the pin fixing plate 15 and fall from the drop port 3 into the storage box 2 for storage. The arrangement channel 22 is set to facilitate accurate feeding.

[0032] Preferably, to improve safety, a protective cover 23 is provided on the platform 1. The protective cover 23 improves safety and prevents accidental contact with the saw blade 6 during the cutting process. The front end of the protective cover 23 is provided with an obstacle passage to facilitate the pusher mechanism 7 to be pushed in. At the same time, to improve safety, an acrylic arc-shaped protective plate 36 is installed at the obstacle passage, and it is ensured that there is an movable gap between the arc-shaped protective plate 36 and the upper surface of the platform 1. This movable gap needs to ensure that the pin pusher plate 14 below can move from the movable gap to the position of the material drop port 3 to realize the cutting operation.

[0033] Preferably, to facilitate the later disassembly of the cutting motor, a U-shaped seat 26 is fixed to the side of the platform 1 away from the material discharge port 3. A clamping seat 27 is fixed to each side of the U-shaped seat 26 by a fixing screw 24. The clamping seat 27 is Ω-shaped, and the clamping seat 27 and the U-shaped seat 26 cooperate to form a clamping jaw for clamping the cutting motor 4. A guide seat 28 is provided on the platform 1 near the material discharge port 3. The guide seat 28 has a guide hole 29 for the output shaft of the cutting motor 4 to pass through. To ensure stability, the... A mounting base 30 is provided on the side of the platform 1 away from the U-shaped base 26. A hinge base 31 is provided on the mounting base 30, and a shaft hole 32 is provided on the hinge base 31. The other end of the rotating shaft 5 is rotatably inserted into the shaft hole 32. In this embodiment, in order to facilitate the replacement of the saw blade 6, a lifting rod 501 is threadedly connected to the end of the rotating shaft 5 away from the cutting motor 4. The other end of the lifting rod 501 is movably inserted into the shaft hole 32. Through the above structural design, the stability of the rotating shaft 5 during rotation is ensured, and it is also convenient to disassemble the various components later.

[0034] Preferably, for ease of operation, an operating handle 33 is provided on the storage box 2. By providing the operating handle 33, it is convenient to pull out the storage box 2 later to realize the recycling operation of the cut needles.

[0035] The working principle of this structure is as follows: The single row of pins 8 is pushed into the limiting notch 16 from the feed port 17. Then, the pusher 13 is pushed close to the saw blade 6 until the pusher 13 is limited by the stop plate 10 and cannot move forward. At this point, the saw blade 6 is just able to be stuck in the corresponding cutting opening 35. As the cutting motor 4 rotates, it drives the saw blade 6 to rotate, cutting the single row of pins 8. In this structure, because multiple saw blades 6 are set with different intervals, pins with different requirements can be cut out at one time. After the cutting is completed, the pin pusher plate 14 is pushed to work. The cut pins are pushed out of the pin fixing plate 15 and fall into the storage box 2 through the material drop port 3 for storage. The arrangement channel 22 facilitates accurate feeding. Therefore, this structure can quickly cut small-batch single-row pins 8 and cut pins of different specifications in one cut. Compared with manual single-cutting, it is more efficient. At the same time, compared with existing automatic pin cutting equipment, this structure is compact in size, easy to store and carry, and more practical and reasonable for cutting small quantities of pins, without being a waste of resources.

[0036] Example 2

[0037] Please see Figure 8-9As shown, the general structure of the single-row needle divider disclosed in this embodiment is the same as that in Embodiment 1. The difference is that, preferably, to further improve safety, the rear of the protective cover 23 is hinged to the platform 1. The platform 1 is equipped with a safety switch 25 that controls the cutting motor 4 to be energized when the protective cover 23 is closed, and controls the cutting motor 4 to be de-energized when the protective cover 23 is open. By setting the safety switch 25 (which is a conventional relay switch electrically connected in the circuit between the connector plug and the cutting motor 4), the cutting motor 4 can only be energized and operated when the safety switch 25 is pressed, further improving safety. It should be noted that the back of the platform 1 is equipped with a connector plug (not shown in the figure) for connecting to an external power source and a control switch. The connector plug, control switch, cutting motor 4, and safety switch 25 form a power supply circuit. When the connector plug is connected to an external power source, pressing the control switch will supply power to the cutting motor 4. However, if the safety switch 25 is not pressed, the cutting motor 4 will not receive power. Only when the safety switch 25 is pressed will the entire circuit be connected, allowing the cutting motor 4 to receive power. How the connector plug, control switch, cutting motor 4, and safety switch 25 are connected to form a power supply circuit is a conventional technology in the field, and therefore will not be described in detail.

[0038] Example 3

[0039] Please see Figure 10 As shown, the general structure of the single-row needle dividing machine disclosed in this embodiment is the same as that in embodiment 1. The difference is that, as a preferred embodiment, in order to facilitate the hand gripping of the platform 1 later, handle grooves 34 are provided on both the left and right sides of the platform 1. By providing handle grooves 34 on both sides of the platform 1, it is convenient for both hands to grip the entire device later.

[0040] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
