DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0023] like Figure 1-Figure 3 As shown, an automatic pin insertion device for an automobile circuit board includes a frame 1. The inner side of the frame 1 is provided with a Y-axis linear module 8, an X-axis linear module 9 and a support plate 6 connected in sequence from bottom to top. A lifting loading platform 7 is provided above the support plate 6, and a feeding mechanism 2 is provided on both sides of the loading platform 7; the inner side of the frame 1 is also provided with a pin insertion mechanism 3 that can move along the Y-axis direction, and the pin insertion mechanism 3 includes a Z-axis linear module 31 parallel to the Z-axis direction, and the output end of the Z-axis linear module 31 is connected to a material picking component 33 for clamping the pins, the material picking component 33 is perpendicular to the loading platform 7, and a pressure sensor 32 is provided between the material picking component 33 and the output end of the Z-axis linear module 31.

[0024] Specifically, a cutter mechanism 4 for cutting materials is also provided below the pin insertion mechanism 3. Driven by the Y-axis linear module 8 and the X-axis linear module 9, the support plate 6 can move horizontally along the X-axis and Y-axis directions, thereby driving the loading platform 7 to move along the X-axis and Y-axis directions; the circuit board to be inserted is transferred to the loading platform 7 through the feeding mechanism 2, and the loading platform 7 then transfers it to the bottom of the pin insertion mechanism 3 for insertion; at the same time, the material picking component 33 clamps the corresponding pins and is cut off by the cutter mechanism 4, and then the material picking component 33 moves forward along the Y-axis direction to the top of the loading platform 7, and the circuit board is driven by the Z-axis linear module 31 to insert the pins.

[0025] During the pin insertion process, the pressure sensor 32 can monitor the insertion force value of each pin insertion process in real time to monitor the abnormality of missing pin insertion and prevent the abnormal situation of missing pin insertion from occurring. That is, in the case of normal pin insertion, the force applied to the pressure sensor 32 changes greatly, and when the pin is inserted accidentally, the force applied to the pressure sensor 32 changes less.

[0026] As described above, the material picking component 33 includes a handle 331 connected to the pressure sensor 32, and the end of the handle 331 is provided with a first clamp 332 and a second clamp 333 that can open and close relative to each other; the material picking component 33 adopts a built-in elastic clamp, and relies on the clamping force of the clamp when picking up the material to keep the material from loosening when taking it out. After the pin insertion action is completed, the clamp is separated from the material without resistance; that is, when picking up the material, one end of the pin is clamped between the first clamp 332 and the second clamp 333.

[0027] Among them, the height of the pin is controlled by adjusting the high-precision fine-tuning screw at the tail of the chuck to meet the process requirements.

[0028] Feeding ports 5 corresponding to the positions of the feeding mechanisms 2 are provided on both sides of the frame 1. One end of the feeding mechanism 2 is located on the inner side of the frame 1, and the other end passes through the feeding port 5 to the outer side of the frame 1. Two feeding mechanisms 2 are provided, and they convey in the same direction: one is used to feed the circuit boards into the frame 1, and the other is used to feed the circuit boards outward. The feeding mechanisms 2 preferably use existing conveyor belts to transport the circuit boards.

[0029] The support plate 6 is equipped with a telescopic component parallel to the Z-axis direction, and the output end of the telescopic component is connected to the loading platform 7; the support plate 6 is also fixedly equipped with a guide column 10 parallel to the Z-axis direction, and the guide column 10 is slidably arranged on the loading platform 7.

[0030] The guide column 10 is connected to the loading platform 7 through a linear bearing to reduce friction and wear between the two; the telescopic component adopts a cylinder, under its drive, the loading platform 7 can be raised and lowered to adapt to the working height of the feeding mechanism 2 and the pin insertion mechanism 3. The guide column 10 plays a guiding and limiting role here to ensure the stability of the lifting and lowering of the loading platform 7.

[0031] In addition, since the cutter mechanism 4 adopts the existing shearing cutting structure, it will produce waste materials such as scraps in the process of cutting the feed pins. In order to facilitate the recycling of the waste, a recycling mechanism for collecting the waste is provided on one side of the cutter mechanism 4 (such as Figure 4 shown).

[0032] The recycling mechanism includes a waste bucket 12 capable of generating negative pressure. A recovery pipe 13 is connected to the top of the waste bucket 12, and multiple branch pipes 14 are connected to the end of the recovery pipe 13. An air pump is connected to the waste bucket 12 to create a negative pressure environment inside it. Under the action of the negative pressure, waste can enter the recovery pipe 13 connected to the waste bucket 12. The end of the recovery pipe 13 is connected to multiple branch pipes 14, which can absorb and recover waste from different locations.

[0033] Among them, the X-axis linear module 9 and the Y-axis linear module 8 both adopt the existing screw-nut drive structure, and the Z-axis linear module 31 can adopt the existing screw-nut drive structure or the cam drive structure; the Z-axis linear module 31 can move along the Y-axis direction, that is, a base is provided on the inner side of the frame 1, and a linear module parallel to the Y-axis direction is installed on the base, and the output end of the linear module is connected to the Z-axis linear module 31, so that the horizontal movement of the Z-axis linear module 31 along the Y-axis direction can be realized.

[0034] Working principle:

[0035] Driven by the X-axis linear module 9, the Y-axis linear module 8 and the telescopic assembly, the loading platform 7 is located between the two feeding mechanisms 2 and is level with them, so that the circuit board on one of the feeding mechanisms 2 can be automatically placed on the loading platform 7; then the loading platform 7 moves a distance below to avoid the height of the feeding mechanism 2, and is driven by the X-axis linear module 9 and the Y-axis linear module 8 to move to the bottom of the pin insertion mechanism 3 for pin insertion.

[0036] During the pin insertion process, the picking component 33 clamps the corresponding pin and is cut off by the cutter mechanism 4. Then the picking component 33 moves forward along the Y-axis direction to the top of the loading platform 7, and the Z-axis linear module 31 drives the circuit board to insert the pin, and the X-axis linear module 9 and the Y-axis linear module 8 adjust the corresponding position to ensure that the pin can be smoothly inserted into the corresponding reserved hole; at the same time, the pressure sensor 32 can monitor the insertion force value of each pin insertion process in real time.

[0037] After the pin insertion is completed, the loading platform 7 returns to between the two feeding mechanisms 2, and the telescopic component lifts it into place so that the other feeding mechanism 2 that discharges the material can transport it to the outside of the frame 1.
