It should be noted that: the slide rails 8 A vertically extending slide groove is provided toward one end of the slide 9, and open grooves are provided on both sides of the slide groove. A slider 901 is fixed to one end of the slide 9, and the outer wall of the slider 901 slides and fits with the inner wall of the slide groove and the open groove, and the width of the slider 901 is greater than the width of the slide 9, so that the slide 9 and the cylinder cover 7 are limited and moved in the vertical direction by the vertical limit sliding of the slider 901 in the slide rail 8; the bottom of the pickling box 1 is rotatably connected to the position corresponding to the connecting cylinder 201, and the outer wall of the stirring shaft 5 is provided with a stirring assembly, and the bottom end of the stirring shaft 5 is transmission-connected to the driving motor 6. Cover plates 4 are rotatably provided on both sides of the top of the pickling box 1. During use, a vertically extending The stirring shaft 5 and the stirring assembly, and the screen frame 2 has not yet been placed in the pickling box 1: the cylinder cover 7 naturally drops to coincide with the top of the connecting cylinder 201 to seal the top opening of the connecting cylinder 201. In the process of loading the diode material into the screen frame 2, it is ensured that the diode will not fall out and the cross-section of the connecting cylinder 201 can be effectively expanded, thereby effectively expanding the cross-sectional range of the stirring assembly; then the screen frame 2 is lowered and placed in the pickling box 1: the top of the stirring shaft 5 will be against the top inner wall of the cylinder cover 7, and as the screen frame 2 gradually drops, the cylinder cover 7 is lifted upward, thereby separating the cylinder cover 7 and the connecting cylinder 201 so that the stirring assembly is directly exposed to the middle area in the screen frame 2.

[0034] In the present invention, a mounting seat 10 is fixed to the top of the stirring shaft 5, and a mounting groove with a circular cross-section is opened on the top of the mounting seat 10. The inner wall of the mounting groove is rotatably connected to a turntable 11 through a bearing. The top of the turntable 11 contacts the inner wall of the top of the cylinder cover 7. When the cylinder cover 7 descends and approaches the top of the stirring shaft 5 as the screen frame 2 comes into contact, the inner wall of the top of the cylinder cover 7 contacts the turntable 11 at the top of the stirring shaft 5 until the cylinder cover 7 rises to the maximum position. The turntable 11 is connected to the mounting seat 10 through rotation, so that excessive wear between the top of the stirring shaft 5 and the cylinder cover 7 is avoided during the rotation of the stirring shaft 5 with the stirring assembly.

[0035] The present invention provides a stirring assembly with two fixing rings 12 installed with the stirring shaft 5, and the two fixing rings 12 are respectively located above and below the stirring shaft 5, and the outer wall of the fixing ring 12 is installed with an extension frame 13 distributed in a ring array, and the extension frame 13 extends horizontally in the radial direction of the stirring shaft 5, and the end of the extension frame 13 away from the fixing ring 12 is rotatably connected to a horizontally placed rotating shaft 14 by a torsion spring, and the rotating shaft 14 is arranged perpendicular to the extension frame 13, and a stirring plate 15 is fixed outside the rotating shaft 14, and a limit block 16 is installed on the extension frame 13 at a position between the stirring plate 15 and the fixing ring 12. The stirring plates 15 outside the two fixing rings 12 are staggered in the circumferential direction. When the net frame 2 is in a normal placement state before being placed in the pickling box 1, the driving motor 6 does not work, and the stirring plates 15 are in a vertical state through the action of the torsion spring and the limit block 16. The stirring plate 15 outside the fixing ring 12 at the lower position extends vertically upward, and the stirring plate 15 outside the fixing ring 12 at the upper position extends vertically downward. At this time, the horizontal cross-section of the fixing ring 12 and its external extension frame 13 and the stirring plate 15 is smaller than the inner cross-section of the connecting cylinder 201. Therefore, when the screen frame 2 is placed, the stirring shaft 5 and the stirring plate 15 can both extend upward along the connecting cylinder 201 into the screen frame 2 and push the cylinder cover 7 upward. After the screen frame 2 is placed, when the stirring shaft 5 rotates, the stirring plate 15 rotates around the stirring shaft 5 along with the stirring shaft 5. Under the action of centrifugation, the stirring plate 15 deflects outward about the rotation axis 14, thereby expanding the stirring range of the stirring shaft 5 and the stirring plate 15, thereby improving the dispersion and pickling effect of the diode material in the screen frame 2. In addition, due to the movable connection of the stirring plate 15, if the parts in the screen frame 2 are unevenly distributed, they will contact the stirring plate 15, causing the stirring plate 15 to reciprocate around the rotation axis 14, further improving the dispersion effect. In addition, the tilted state of the stirring plate 15 can effectively prevent the diode material from entering the middle position and falling out of the connecting cylinder 201 during rotation and centrifugation.

[0036] In the present invention, a plurality of through holes 152 are provided at both ends of the stirring plate 15 in the horizontal direction, and the other end of the through hole 152 is arranged at the side of the stirring plate 15 away from the stirring shaft 5, so that when the stirring plate 15 rotates along the circumference of the stirring shaft 5, the bent through hole 152 is used to improve the dispersion effect of the liquid flow, thereby improving the flow pickling effect of the liquid flow around the diode material. A groove 151 is provided on the side of the stirring plate 15 close to the stirring shaft 5, and the groove 151 is opened at the end away from the rotating shaft 14, and the width of the groove 151 gradually increases in the direction away from the rotating shaft 14. The size of the stirring plate 15 of the fixed ring 12 at the lower position is gradually increased, so that the stirring plate 15 of the fixed ring 12 at the lower position is expanded upward through the inclined state and the groove 151, guiding the liquid flow to carry the diode material upward, while the stirring plate 15 of the fixed ring 12 at the upper position is expanded downward through the inclined state and the groove 151, guiding the liquid flow to carry the diode material downward, and coordinating with the staggered arrangement of the upper and lower stirring plates 15, the circular rotation process of the liquid flow will carry the diode material to flow in the area between the upper and lower stirring plates 15, thereby improving the pickling effect and pickling efficiency of the diode material.

[0037] In the present invention, the stirring assembly is further provided with two slip rings 17, which are located between the two fixed rings 12. The inner wall of the slip ring 17 is slidably connected to the outer wall of the stirring shaft 5. A plurality of movable plates 18 are fixed to the outer wall of the slip ring 17. Limit rings 19 are fixed to the outer wall of the stirring shaft 5 above and below the slip ring 17. It should be noted that: each slip ring 17 is correspondingly provided with two limit rings 19, so that the two slip rings 17 are limited to different height positions by the limit rings 19; so that the slip ring 17 can rotate freely around the outer wall of the stirring shaft 5, and the slip ring 17 can be vertically displaced between the two limit rings 19; when the stirring shaft 5 rotates with the stirring plate 15, under the condition that the peripheral diode material is unevenly distributed, the liquid flow in the same horizontal and vertical directions will continuously change and collide with the movable plate 18, so as to also disperse the collision of the liquid flow between the movable plate 18 and the stirring plate 15, thereby further improving the contact pickling effect of the liquid flow and the diode material by dispersing the liquid flow.

[0038] In the present invention, a movable groove 181 is provided at one end of the movable plate 18 away from the slip ring 17, and the depth of the movable groove 181 gradually increases from the middle position toward the top and bottom. The top and bottom of the movable groove 181 are both open, and a perforation 182 is provided on the side of the movable plate 18. Through the inclined surface setting of the movable groove 181 and the perforation 182, the movable plate 18 can move relative to the screen frame 2 under the action of the liquid flow, and the movable plate 18 will move relative to the stirring shaft 5, and the inclined surface setting of the movable groove 181 is used to improve the dispersion and guidance effect of the liquid flow.

[0039] Example 2: Reference Figures 1-12, a pickling equipment for diode processing, based on Example 1, an intermediate cavity 20 is provided between the outer side of the screen frame 2 and the inner side of the pickling box 1, it should be noted that: the intermediate cavity 20 is distributed at both ends, both sides and the outer side of the bottom of the screen frame 2; a stirring paddle 27 is fixed in the intermediate cavity 20 below the outer wall of the stirring shaft 5, the stirring paddle 27 is located below the connecting cylinder 201, and when the stirring paddle 27 rotates, it guides the liquid flow toward the top of the connecting cylinder 201, cooperates with the inclined setting of the stirring plate 15 at the lower position to prevent the diode material from falling out of the screen frame 2 from the connecting cylinder 201.

[0040] In the present invention, the outer wall of the pickling box 1 is equipped with a plurality of vertically extending sleeves 21, both ends of the sleeve 21 extend horizontally toward the middle cavity 20, and the inner walls of both ends of the sleeve 21 are slidably connected with pistons 25, and the piston 25 is fixed with a sleeve rod 22 toward the middle cavity 20. The pickling box 1 is provided with a hole at the position corresponding to the sleeve rod 22, and the outer wall of the sleeve rod 22 slides in a sealed manner with the inner wall of the hole. A sleeve plate 23 is fixed at one end of the sleeve rod 22 extending into the middle cavity 20, and a spring 26 is connected between the end of the piston 25 away from the sleeve rod 22 and the inner wall of the sleeve 21. The plurality of sleeves 21 are distributed on both sides of the four vertical edges of the pickling box 1, and the sleeve plate 23 is fixed with a plurality of needle rods 24 toward the screen frame 2. The needle rods 24 correspond to the mesh positions on the outside of the screen frame 2, and the stirring plates 15 staggered at the upper and lower positions rotate with the stirring shaft 5. During the process, when the stirring plate 15 approaches the corresponding position of the sleeve 21, the liquid flow at the corresponding position will be centrifuged outward and hit the side wall of the sleeve 23. For example, when the stirring plate 15 at the lower position rotates and approaches, the liquid flow at the corresponding position below will be centrifuged outward and hit the sleeve 23 outward. The sleeve 23 carries the piston 25 to squeeze the spring 26 and the air cavity in the sleeve 21, so that the sleeve 23 above the same sleeve 21 moves outward to push the liquid flow. On the one hand, the upper sleeve 23 moves inward to collide with the outward liquid flow generated when the subsequent upper stirring plate 15 approaches, thereby improving the liquid flow movement effect. On the other hand, the needle rod 24 of the upper sleeve 23 is extended into the mesh of the screen frame 2 to push the material remaining at the corners of the screen frame 2 toward the middle position, thereby further improving the pickling effect of the accumulated material in the screen frame 2.
