Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling equipment, and more specifically, the utility model relates to a waste splitting device for vehicle seat sensors. Background Art

[0002] An automotive seat sensor is a pressure-triggered contact sensor, generally used in the automotive seat occupant sensing system. It can analyze whether there is an occupant on the automotive seat and feed this information back to the in-vehicle computer, thus playing the switching control function for the seat belt warning device and the airbag ejection device. Since the seat styles of different vehicles are not the same, the automotive seat sensor needs to be designed according to the shape, hardness, and tightness of the seat skin of the automotive seat for the shape of the sensor and the sensitivity of the contacts.

[0003] When operators disassemble waste seat sensors, they often need to remove the sensor components from the circuit board for classification and recycling. However, in the actual disassembly process, the sensor components generally need to be heated by a hot air gun before they can be disassembled from the circuit board. However, since the circuit board of the sensor is at a high temperature after heating, this makes it impossible for the operator to immediately remove the components from the circuit board, which greatly limits the speed of the disassembly operation. Therefore, it needs to be improved. Summary of the Utility Model

[0030] A splitting mechanism, the splitting mechanism is arranged on the left side of the installation box 4;

The left and right movement of the toothed plate 7 causes the gear 8 and the entire installation box 4 to rotate.

[0032] When the pneumatic cylinder 6 operates, the toothed plate 7 will start to move to the left. Since the toothed plate 7 and the gear 8 are meshed with each other, the gear 8 will start to rotate around the fixed shaft 3 driven by the meshing of the toothed plate 7, and the movement of the gear 8 will drive the installation box 4, so that the entire installation box 4 starts to rotate together with the gear 8.

[0033] Among them, the lower surface of the fixing plate 1 is fixedly connected with a support leg 9, the bottom end of the support leg 9 is fixedly connected with a bottom plate 10, and the middle of the upper surface of the bottom plate 10 is movably connected with a collection box 11.

[0034] The rotation of the entire installation box 4 will cause the sensor elements after heating and desoldering to fall into the interior of the collection box 11.

[0035] Among them, a first motor 12 is fixedly installed on the lower surface of the installation box 4, the other end of the output shaft of the first motor 12 is fixedly sleeved with a driving shaft 13, the top end of the driving shaft 13 penetrates through the installation box 4 and extends into the interior of the installation box 4, and the outer surface of the driving shaft 13 is fixedly sleeved with a driving rod 14 located inside the installation box 4.

[0036] When the first motor 12 operates, the drive shaft 13 and the drive rod 14 will start to rotate.

[0037] Both the left and right ends of the drive rod 14 are hinged with driven rods 15. The other end of the driven rod 15 is hinged with a moving block 16. The number of moving blocks 16 is two. The outer surfaces of the two moving blocks 16 are both movably connected to the inner surface of the placement plate 5.

The number of clamping plates 17 is two. The positions of the two clamping plates 17 are symmetric about the left and right of the installation box 4.

[0038] The rotation of the drive rod 14 will drive the driven rod 15 and cause the driven rod 15 to start rotating. At the same time, the other end of the driven rod 15 will drive the moving block 16, causing the two moving blocks 16 as a whole to start moving towards each other along the inner surface of the placement plate 5.

[0039] Both the left and right ends of the upper surface of the fixed plate 1 are fixedly connected with mounting plates 18. The top of the left surface of the mounting plate 18 is fixedly installed with a second motor 19. The other end of the output shaft of the second motor 19 is fixedly sleeved with a lead screw 20. The right end of the lead screw 20 penetrates through the mounting plate 18 and extends to the right side of the mounting plate 18. The outer surface of the lead screw 20 is movably sleeved with the inner surface of the mounting plate 18. The right side of the outer surface of the lead screw 20 is threadedly sleeved with a movable block 21.

[0040] When the second motor 19 operates, the lead screw 20 will start to rotate.

[0041] The front side of the top of the inner surface of the mounting plate 18 is fixedly connected with a connecting plate 22. The outer surfaces of the upper and lower sides of the connecting plate 22 are both movably connected with limiting blocks 23 located in front of the movable block 21. The rear surface of the limiting block 23 is fixedly connected with the front surface of the movable block 21.

[0042] Due to the design of the connecting plate 22 and the limiting block 23, the stability of the whole movable block 21 during left - right movement is ensured.

[0043] The rear side of the upper surface of the movable block 21 is fixedly installed with a hot air blower 24. The upper surface of the hot air blower 24 is fixedly connected with an air inlet 25. The lower surface of the hot air blower 24 is fixedly connected with an air outlet 26. The bottom end of the air outlet 26 penetrates through the movable block 21 and extends to the inside of the movable block 21 and is fixedly connected with a hot air gun 27. The outer surface of the hot air gun 27 is fixedly sleeved with the inner surface of the movable block 21.

[0044] When the hot air blower 24 operates, the hot air blower 24 will draw in outside air through the air inlet 25 and heat it inside the hot air blower 24. The heated high - temperature air flow will be sprayed onto the outer surface of the circuit board through the air outlet 26 and the hot air gun 27. At this time, the solder joints on the circuit board will melt under the high temperature of the air flow, making the sensor components on the circuit board removable.

[0045] Working principle and usage process of the utility model:

[0046] First, the operator places the waste circuit board welded with sensor components on the upper surface of the placement board 5, and then the operator starts the first motor 12. As the first motor 12 operates, the driving shaft 13 and the driving rod 14 will start to rotate, and the two driven rods 15 will start to rotate respectively with the left and right ends of the driving rod 14 as the axes under the drive of the driving rod 14. At the same time, the other ends of the two driven rods 15 will drive the two moving blocks 16, causing the two moving blocks 16 as a whole to start moving towards the circuit board. Finally, the two clamping plates 17 will clamp the circuit board, thus fixing the position of the circuit board.

[0047] Then the operator starts the second motor 19 and the hot air blower 24. The operation of the second motor 19 will cause the lead screw 20 to start rotating, which will cause the moving block 21 as a whole to start moving to the left. The operation of the hot air blower 24 will cause the outside air to enter the inside of the hot air blower 24 through the air inlet 25 for heating. The heated hot air flow will be sprayed on the welding points of the circuit board and the sensor components through the air outlet 26 and the hot air gun 27. Finally, under the combined action of the moving block 21 and the hot air gun 27, the sensor components can be removed from the circuit board.

[0048] At this time, the operator starts the air cylinder 6 again. As the air cylinder 6 operates, the toothed plate 7 will start to move to the left. Since the outer surfaces of the toothed plate 7 and the gear 8 are meshed with each other, the rotation of the toothed plate 7 will drive the gear 8, causing the gear 8 and the installation box 4 as a whole to start rotating around the fixed shaft 3 as the axis. Finally, as the installation box 4 as a whole rotates, the desoldered sensor components will break away from the circuit board and fall into the inside of the collection box 11 under the action of gravity, thus completing a disassembly operation on the waste seat sensor once.

Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
