Description

Technical Field

[0001] The present invention relates to the technical field of chip waste recycling, and in particular to a chip production waste recycling device and a recycling method. Background Art

[0002] With the widespread application and upgrading of electronic products, the demand for chips is also increasing. As production increases, chip scraps and scrap materials will also increase year-on-year. However, the raw materials of these chips contain precious metals and other resources. If they are directly discarded, it will cause great pollution and waste to the environment and resources. In order to promote sustainable development, it is necessary to recycle these chip wastes.

[0003] The current chip recycling process generally involves collecting chip scraps and scrap materials, crushing them first, then putting the fragments crushed to specified specifications into a grinding machine, and finally separating the useful materials from the ground powder through gravity separation or air flow separation for reuse. The existing grinding methods generally increase the grinding time to promote the fineness of the powder, thereby ensuring that the ground powder meets the requirements while avoiding the need for repeated grinding.

[0004] Although the existing grinding and recycling method reduces the labor intensity of the staff, its long grinding process will reduce the recycling efficiency of chip scraps and scrap materials. These recycled materials will eventually need to be put back into the production line, but in terms of cost, the shorter the operation cycle of the production line in each round of production, the better. In particular, chip processing will produce huge energy consumption, and restarting after shutdown will face greater losses. In this way, the slow recycling process will greatly slow down the recycling rate of waste, thereby causing an overall reduction in production rate or delayed utilization of recyclables, which will have a greater negative impact on the production cost of each round. In view of this, the present invention proposes a chip production waste recycling device and recycling method. Summary of the invention

[0045] A method for using a chip production waste recycling device, the steps are as follows:

[0046] S1, putting chip waste into the device from the feed port 2;

[0047] S2, using the driving mechanism 10 to drive the grinding wheel 5 to rotate and roll back and forth along the grinding groove 6;

[0048] S3, the driving mechanism 10 will intermittently open the leakage hole 7 during grinding, and the powder that meets the standards will enter the discharge port 3 from the leakage hole 7;

[0049] S4. The chip waste powder ground to a standard particle size is collected from the discharge port 3.

[0050] Working principle: The staff can set the device around the chip production line. If there are scraps or unusable defective products in the chip production process, the staff can put them into the shell 1 from the feed inlet 2. Then, under the guidance of the feed inlet 2, these wastes will directly fall into the side of the shell where a large number of second crushing pestles 16 are set;

[0051] Before the staff puts the waste into the machine, they can use the motor 32 to drive the driving mechanism 10 of the device to operate. When the motor 32 drives the rotating shaft 31 to rotate, the bidirectional thread groove 33 on the rotating shaft 31 will cause the sliding seat 24 to translate back and forth along the inner cavity 29 through the guide block 34. Since the sliding seat 24 is slidably connected with two baffles 25, and the length of the three together is much greater than the length of the shaft groove 12, and the height of the three can also completely cover the highest point and the lowest point of the shaft groove 12, the crushed chip fragments will not enter the shaft groove 12, and the position of the powder has a large height difference with the shaft groove 12, and the internal connection between the device and the outside world is small and small, so the internal part of the device will not generate dust to cause The problem of chip powder entering the shaft groove 12 is that when the sliding seat 24 moves back and forth, the movable plate 28 thereon will drive the wheel shaft 11 to move together. Because the shaft groove 12 that slides with the wheel shaft 11 is opened on the inner wall of the rear side of the shell 1, the wheel shaft 11 will swing in an arc shape under the pressure of the inner wall of the shaft groove 12 when moving forward and backward. This path is exactly consistent with the bottom surface of the grinding groove 6, so that the chip can be ground. In addition, the tooth column 13 opened on the wheel shaft 11 is meshed with the tooth groove 14. The grinding wheel 5 will also rotate during the swinging process along the path. The rotation can prevent the grinding wheel 5 from pushing the chip fragments back and forth during the translation, ensuring that the chip waste can be fully crushed by the grinding wheel 5.

[0052] Before the chip is crushed and ground by the grinding wheel 5, it will pass through the first crushing pestles 15 and the second crushing pestles 16 during the swing of the grinding wheel 5. The movement path of the first crushing pestle is to move back and forth in a spiral shape, and the second crushing pestles 16 are dispersed on the movement path and will not come into contact with it. Moreover, the gap between any pair of the first crushing pestles 15 and the second crushing pestles 16 will change in size many times during the movement, so that the scraps and defective products of the chip will be cut off and broken by the back and forth staggered movement of the two after falling into them, so that the chip waste will be preliminarily broken before being ground into powder, which reduces the difficulty of grinding and improves the grinding efficiency.

[0053] The movement of the grinding wheel 5 starts from the U-shaped end of the extrusion rod 35. In the process of moving toward the L-shaped end of the extrusion rod 35, the support plate 9 and the insertion rod 8 will maintain the blocking state of the leakage hole 7. This design is to prevent the grinding wheel 5 from forcibly pressing the chip fragments into the leakage hole 7 during the grinding process to prevent part of the leakage hole 7 from being blocked. At the same time, it can also make the chip waste all around have solid contact surfaces, which reduces the gap and improves the chip grinding effect, and avoids the special shape of chip waste from being difficult to be ground into powder due to the existence of the leakage hole 7. When the grinding wheel 5 moves to the L-shaped end of the extrusion rod 35, the sliding seat 24 will press the extrusion rod down through the inclined surface of the L-shaped end of the extrusion rod 35. At this time, the lower end of the extrusion rod 35 is in a state of being in contact with the extrusion plate 39. Its descent will cause the lower end of the extrusion rod 35 to generate pressure on the extrusion plate 39 and prompt it to move forward. The forward movement of the extrusion plate 39 causes the second magnet 42 to extend out of the first plate groove 40. When the first and second magnets 21 are pushed into the vertical groove 22, the repulsive force between the first and second magnets 21 will make the first magnets 21 have a downward movement tendency. However, at this moment, the fixing plate 43 is still limited, and the support plate 9 and the slide bar 19 cannot move downward. After the extrusion plate 39 is squeezed to the front, the extrusion plate 39 no longer blocks the downward movement path of the extrusion rod 35. Subsequently, the extrusion rod 35 will pass through the first plate groove 40, and the slot 51 located at the lower part will correspond to the lower end of the fixing rod 49 in the cavity 48 of the side wall of the first plate groove 40. The upper and lower ends of the fixing rod 49 were originally restricted by the L-shaped end of the extrusion rod 35 and the extrusion plate 39, respectively. At this time, the restrictions of the two are released, so the extrusion rod 35 will pop out of the cavity 48 and use its own upper and lower ends to respectively fit into the top of the extrusion rod 35 and the slot 51, so that the extrusion rod 35 can no longer rebound, and its upper end will extend into the inner cavity 29 to wait for the extrusion of the sliding seat 24, and the length of the extrusion into the inner cavity 29 is greater than the length of the fixing rod 49 inserted into the slot 51.

[0054] On the other hand, the guide rod 46 located inside the fixed plate 43 will descend along the vertical portion of the guide groove 47 during the first descent of the extrusion rod 35, and will not affect the fixed plate 43. When the grinding wheel 5 and the sliding seat 24 move to the U-shaped end of the extrusion rod 35 again, the extrusion rod 35 is restricted from rising after being lowered. In this way, the lowest point of the inclined surface on the U-shaped end of the extrusion rod 35 will descend to a position corresponding to the bottom surface of the sliding seat 24. When the sliding seat 24 moves to the U-shaped end of the extrusion rod 35 in the last round, the upper end of the U-shaped end of the extrusion rod 35 corresponds to the side groove 38, so there will be no impact on the extrusion rod 35. The downward pressure effect means that there is no space in the side groove 38 to accommodate the upper end of the U-shaped end of the extrusion rod 35. The extrusion rod 35 will drop again under the pressure of the sliding seat 24. The process of its drop will cause the guide rod 46 to move the fixed plate 43 backward by squeezing the guide groove 47, thereby releasing the restriction on the support plate 9. The support plate 9 will drop rapidly under the repulsive force of the two magnets and rotate along the fixed axis 18 to an inclined state with a low front and a high back under the guidance of the inclined surface of the bottom surface of the discharge port 3, so that the chip waste powder leaked from the leakage hole 7 can leak into the discharge port 3 and slide to the front along the discharge port 3. The staff only needs to collect the powder in the container in the front.

[0055] Then the sliding seat 24 and the grinding wheel 5 will move toward the L-shaped end of the extrusion rod 35 again. Because the top surface of the fixing rod 49 is an inclined structure, the descent of the extrusion rod 35 will produce an extrusion effect on the fixing rod 49 through the top surface of the lower slot 51, thereby forcing it to move part of the way into the cavity 48. Similarly, the partition plate 53 that cannot deflect upward can also further compress the fixing rod 49 into the cavity 48. When the extrusion rod 35 drops to the lowest point, the fixing rod 49 will correspond to the upper slot 51 again. At this time, the fixing rod 49 will pop out again and get stuck in the upper slot 51 to restrict it again. The height of the extrusion rod 35 is controlled. Because there are enough flat parts on the outer sides of the inclined surfaces at both ends of the extrusion rod 35, there is enough time for the fixing rod 49 to be inserted into the slot 51. During this process, the leakage hole 7 will be in an open state, so that the powder in the grinding groove 6 has enough time to leak out. At the same time, the chip fragments in the grinding groove 6 can be turned over by the movement of the grinding wheel 5, so that the chip powder blocked by the large pieces of chip waste can also fall below during the turning. Although some chips will be forced into the leakage hole 7 to cause blockage during this process, the subsequent insertion rod 8 will return to its original position. , and then this part of the debris can be pushed out of the leakage hole 7. When the sliding seat 24 moves to the L-shaped end position again, it will press the upper end of the fixing rod 49 extending into the inner cavity 29, and then the fixing rod 49 will be moved out of the upper slot 51, and the extrusion rod 35 that has lost its fixation will return to its original position under the action of the second support spring 37. During this period, although the extrusion of the upper end of the fixing rod 49 by the sliding seat 24 will be released as the sliding seat 24 moves toward the U-shaped end of the extrusion rod 35 again, the upper end of the fixing rod 49 cannot be rebounded into the inner cavity 29 again due to the outer wall of the extrusion rod 35. 5, and, although the position of the lower end of the fixed rod 49 will correspond to the lower slot 51 during the rising process of the extrusion rod 35, the end of the fixed rod 49 will be turned downward by the partition 53 on the upper side during the descent, and then the partition 53 will block the lower slot 51, so that the fixed rod 49 cannot be plugged into the lower slot 51 during the rising process of the extrusion rod 35, thereby ensuring that the device can be smoothly reset, and the remaining structures will also return to their original positions under the action of their corresponding elastic members, and finally the sliding seat 24 will restart the next round of grinding and feeding operations after moving to the U-shaped end side of the extrusion rod 35.
