The clamp 4337 is connected to the driving rod D4336, which is sleeved on the outer surface of the clamp, and the roller groove 4338 is provided on the inner wall of the clamp 4337. The roller 4339 is fixedly arranged inside the roller groove 4338. The clamp 4337 corresponds to one end of the water spray pipe 23. The epoxy molding compound can be clamped by the rotation of the driving rod D4336, and the centering of the epoxy molding compound can be conveniently adjusted by the roller 4339. Finally, the conical plate 4334 and the leakage groove 4333 cooperate to discharge the sprayed liquid.

[0032] One side of the fuselage 1 is rotatably connected to a machine door 11, one side of the fuselage 1 is provided with a feed port 12, and the other side of the fuselage 1 is provided with a discharge port 13. A filter screen 14 is fixedly installed on the inner wall of the fuselage 1, and the filter screen 14 is directly below the regulating component 3 and the transport component 4. A V-shaped water trough 15 is provided at the bottom of the fuselage 1, and a water outlet 16 is provided on one side of the V-shaped water trough 15. The epoxy molding compound after grinding can be discharged through the filter screen 14, and the sprayed coolant can be discharged through the V-shaped water trough 15.

[0033] Specifically, when the epoxy molding compound body 44 needs to be ground, the worker only needs to let the driving rod C42 and the clamping assembly 433 rotate to the position of the feed port 12, and then the worker can put the epoxy molding compound body 44 into the clamping assembly 433. At this time, the clamping motor 4335 can be started to let the driving rod D4336 clamp the epoxy molding compound body 44. Because the roller 4339 is fixedly installed on the inner wall of the clamp 4337, the epoxy molding compound body 44 can still move slightly when being clamped by the clamp 4337. After that, when the epoxy molding compound body 44 is clamped, the driving rod C42 can be started again to let the clamping assembly 433 bring the epoxy molding compound body 44 to the inside of the adjusting component 3. At this time, the next The clamping assembly 433 of the group will come to the feed inlet 12, at this time, the epoxy molding compound body 44 can continue to be added, when the epoxy molding compound body 44 comes to the inside of the adjusting component 3, the electric telescopic plate 34 can be started to make the grinding assemblies 36 on both sides close to each other, so that the epoxy molding compound body 44 can be centered inside the clamp 4337, paving the way for subsequent grinding, when the epoxy molding compound body 44 is centered, the grinding assembly 36 can be separated, and at the same time, the grinding motor 365 can be started to make the driving rod B366 rotate with the coarse grinding disc 367 at high speed, at this time, the electric telescopic plate 34 will continue to bring the grinding assembly 36 closer, so as to coarsely grind the epoxy molding compound body 44, when the coarse grinding of the epoxy molding compound body 44 reaches the index, The grinding assembly 36 can be separated and the flip motor 362 can be started at the same time, so that the driving rod A363 rotates with the fixed block 35. At this time, the coarse grinding disc 367 and the fine grinding disc 368 are interchanged, and the epoxy molding compound body 44 can be finely ground. While the epoxy molding compound body 44 is being ground, the water pump 24 can be started to pump the coolant inside the water storage tank 22 into the water spray pipe 23, and then spray it out. Because one end of the water spray pipe 23 is opposite to the epoxy molding compound body 44, the epoxy molding compound body 44 can also be cooled by spraying coolant during grinding. After the coolant cools the epoxy molding compound body 44, a part of the coolant will directly fall into the V-shaped water tank 15 and finally there is The cooling liquid is discharged from the water outlet 16, and the other part of the cooling liquid enters the groove 4332 of the clamping plate 4331. Because there are water leakage grooves 4333 and conical plates 4334 inside the groove 4332, the other part of the cooling liquid will enter the V-shaped water groove 15 along the water leakage groove 4333 and finally be discharged. Finally, when the ground epoxy molding material body 44 is first brought to the same horizontal line with the feed inlet 12 by the driving rod C42, it will wait for the next group of epoxy molding material bodies 44 to be ground before it can be brought to the top of the filter 14 by the driving rod C42. At this time, the vertical clamping assembly 433 will release the clamp 4337, allowing the ground epoxy molding material body 44 to fall onto the surface of the filter 14, and finally be discharged from the fuselage 1 along the inclined surface of the filter 14.This achieves the effect of not needing to frequently replace the grinding disc when grinding the epoxy molding compound body 44.
