Description

Technical Field

[0001] This utility model relates to the field of automatic pin insertion machine technology, specifically to a pin insertion feeding device for an automatic pin insertion machine. Background Technology

[0002] An automatic pin insertion machine is an automated device used to precisely insert metal pins (such as terminals, connector pins, etc.) into a circuit board (PCB) or other substrate. It is widely used in electronics manufacturing, automotive electronics, home appliances and other fields.

[0003] Existing automatic pin insertion machines typically use a vibratory feeder to feed terminals one by one to the worktable. The outlet of the vibratory feeder is connected to the worktable via a feeding chute. To facilitate the feeding of terminals towards the side of the worktable inside the feeding chute, a vibrator is usually installed at the bottom of the feeding chute to drive its vibration. However, electromagnetic or motor-driven vibration can generate significant noise, and continuous vibration may lead to fatigue of other mechanical structures, resulting in loosening or increased noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pin feeding device for an automatic pin insertion machine, including a vibratory plate, a feeding chute disposed at the outlet of the vibratory plate, and several support legs fixed at the bottom of the feeding chute. A first conveyor belt and a second conveyor belt are symmetrically arranged on both sides of the inner width of the feeding chute. A terminal travel channel is formed between the first conveyor belt and the second conveyor belt, and the first conveyor belt and the second conveyor belt rotate in opposite directions to convey terminals to the side away from the vibratory plate.

[0006] Furthermore, the first conveyor belt includes a first driving wheel and a first driven wheel that are rotatably installed on both sides of the bottom length inside the feeding chute, and the first driving wheel and the first driven wheel are connected by a first belt.

[0021] Please see Figure 1-5This utility model provides an embodiment of an automatic pin insertion machine's pin feeding device, including a vibratory plate 1, a feeding chute 2 disposed at the outlet of the vibratory plate 1, and four support legs 3 fixed to the bottom of the feeding chute 2. The specific structure of the vibratory plate 1 is prior art and will not be described in detail here. It vibrates to one side to discharge the pin. The feeding chute 2 is horizontally disposed at the outlet of the vibratory plate 1 under the support of the support legs 3, and the side of the feeding chute 2 away from the vibratory plate 1 is connected to the worktable (not shown in the figure). The inner width of the feeding chute 2 is symmetrically provided with a first conveyor belt 4 and a second conveyor belt 5. A terminal travel channel is formed between the first conveyor belt 4 and the second conveyor belt 5, and the first conveyor belt 4 and the second conveyor belt 5 rotate in opposite directions to transport the terminal to the side away from the vibratory plate 1.

[0022] Reference Appendix Figure 5 The first conveyor belt 4 includes a first driving wheel 401 and a first driven wheel 402, which are rotatably installed on both sides of the bottom length inside the feeding chute 2. The first driving wheel 401 and the first driven wheel 402 are connected by a first belt 403. The bottom end of the first driving wheel 401 is provided with a motor 404 that drives its rotation.

[0023] Reference Appendix Figure 5 The second conveyor belt 5 includes a second driving wheel 501, a second driven wheel 502, and a drive module for driving the second driving wheel 501 to rotate, respectively installed on both sides of the bottom length of the feeding chute 2. The second driving wheel 501 and the second driven wheel 502 are connected by a second belt 503. In this embodiment, the first belt 403 and the second belt 503 are of equal size and are symmetrically arranged on both sides of the width inside the feeding chute 2. In this embodiment, the second driving wheel 501 is located inside the feeding chute 2 on the side close to the first driven wheel 402, and the shafts of the second driving wheel 501 and the first driven wheel 402 are connected. Both extend to the bottom of the feeding chute 2. The drive module includes a first gear 504 and a second gear 505, which are coaxially fixed on the second driving wheel 501 and the first driven wheel 402, respectively. The first gear 504 and the second gear 505 are both located below the feeding chute 2 and mesh with each other, which can drive the first belt 403 and the second belt 503 to move in opposite directions. Alternatively, the drive module can be directly set as a motor installed at the bottom of the second driving wheel 501 or the second driven wheel 502, which can drive the second belt 503 to rotate in opposite directions to the first belt 403.

[0024] In this embodiment, a top cover 6 is provided on both sides of the top width of the feeding chute 2, and a gap is reserved between the two top covers 6 to accommodate the terminal conveying. Since the length of the terminal or the conveying method may not be fixed, when the terminal is conveyed vertically between the first belt 403 and the second belt 503, the top of the terminal can extend to the outside of the feeding chute 2 through the gap between the two top covers 6. At the same time, the two top covers 6 can also limit the conveying of the terminal.

[0025] In this embodiment, the needle insertion feeding device of the automatic needle insertion machine further includes an adjustment mechanism 7 for adjusting the distance between the opposite sides of the first belt 403 and the second belt 503. The adjustment mechanism 7 includes two support bases 702 respectively disposed below the first conveyor belt 4 and the second conveyor belt 5, and a linear drive 703 for adjusting the distance between the two support bases 702. The top of each support base 702 is rotatably provided with four adjusting wheels 701 via a rotating shaft. The adjusting wheels 701 are rolledly connected to the first belt 403 and the second belt 503. The two sets of adjusting wheels 701 respectively tighten the first belt 403 and the second belt 503. The opposite sides of the first belt 403 and the second belt 503 are parallel to the length direction of the feeding chute 2. The support bases 702 are all located below the feeding chute 2, and the feeding chute 2 is provided with a accommodating mechanism for the adjusting wheels. The 701 rotating shaft moves in opposite directions or towards each other along the width of the feeding chute 2, with clearance sliding holes 201. The linear drive 703 is specifically a threaded rod installed at the bottom of the feeding chute 2 along the width of the feeding chute 2, and a handwheel or motor that drives the threaded rod to rotate. The threads at both ends of the threaded rod are opposite. When it rotates, it can drive the two support bases 702 to move in opposite directions at the same time. This can drive the adjusting wheels 701 on the inner side of the first belt 403 and the second belt 503 to move to the middle or to the sides at the same time. Then, the distance between the first belt 403 and the second belt 503 can be adjusted according to the size of the terminal to be conveyed, making it more versatile. At the same time, the four adjusting wheels 701 keep the first belt 403 and the second belt 503 taut at all times, so as to avoid affecting the rotation of the first belt 403 and the second belt 503.

[0026] In this embodiment, the two top covers 6 are respectively located above the first conveyor belt 4 and the second conveyor belt 5, and the adjusting wheels 701 on the inner side of the first conveyor belt 4 and the second conveyor belt 5 are rotatably connected to the two top covers 6 through rotating shafts, so that the top covers 6 and the adjusting wheels 701 move synchronously. When adjusting the position of the adjusting wheels 701, the position of the two top covers 6 can be adjusted synchronously, so that the distance between the two top covers 6 matches the size of the terminal to be conveyed. There is no need to set up an additional drive mechanism for the top covers 6, which is convenient and labor-saving, and reduces equipment investment.

[0027] Working principle: Under the vibration of the vibratory plate 1, the terminals enter the feeding chute 2 one by one. The motor 404 drives the first driving wheel 401 to rotate, which cooperates with the first driven wheel 402 to drive the first belt 403 to rotate. The second gear 505 at the bottom of the first driven wheel 402 and the first gear 504 at the bottom of the second driving wheel 501 mesh with each other, which in turn drives the second driving wheel 501 and the first driven wheel 402 to rotate in opposite directions, and then drives the second belt 503 and the first belt 403 to rotate in opposite directions. When the conveying terminal moves to the middle of the first belt 403 and the second belt 503, it can move to one side to discharge under the action of friction. When it is necessary to feed terminals of different sizes, the two support bases 702 are driven to move synchronously to the center or to both sides by the linear drive 703, which drives the adjusting wheels 701 on both sides to move synchronously to the center or to both sides. This adjusts the gap between the first belt 403 and the second belt 503, and keeps the first belt 403 and the second belt 503 taut, which facilitates the feeding of terminals of different sizes. Since the top of the adjusting wheel 701 is rotatably connected to the top cover 6 through a rotating shaft, the top cover 6 and the adjusting wheel 701 move horizontally synchronously, which adjusts the distance between the two top covers 6 synchronously.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
