DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In this embodiment, refer to Figure 1-4 A screening device for electronic ceramics, the screening device consists of a rotary vibrating screen 1, a conveying table 2, a discharge table 3 and a stamping table 6. A number of trays 4 arranged in sequence are placed on the surface of the conveying table 2, and small ceramic pieces 5 are placed on the trays 4. The discharge port of the rotary vibrating screen 1 is connected to the entrance end of the conveying table 2. The small ceramic pieces 5 arranged and sent out by the rotary vibrating screen 1 are released one by one and fall in sequence onto the trays 4 for receiving on the conveying table 2 below. The rotary vibrating screen 1 has the function of discharging small ceramic pieces 5 and can deliver the small ceramic pieces 5 out in an orderly manner, and the conveying table 2 can choose step-by-step transmission, so that it can ensure that the displacement distance of the tray 4 is just enough to transmit a single small ceramic piece 5.

[0024] From the attached Figure 1 And attached Figure 2 It can be seen that the unloading platform 3 and the punching platform 6 are respectively arranged on both sides of the conveying platform 2 and are aligned in position. The unloading platform 3 and the punching platform 6 are respectively arranged along the two side edges of the conveying platform 2.

[0025] The top of the stamping table 6 is suspended above the conveying table 2. A hydraulic lifting platform 9 is provided on the stamping table 6. The hydraulic lifting platform 9 is above the conveying table 2. A cylinder 10 is installed at the bottom of the hydraulic lifting platform 9. The bottom output end of the cylinder 10 is connected to the detection straight rod 7 through a pneumatic rod. The detection straight rod 7 is perpendicular to the table surface of the conveying table 2 and is vertically inserted into the through hole formed in the center of the small ceramic piece 5.

[0026] As the conveying platform 2 is conveyed step by step, each tray 4 is conveyed to the bottom of the detection rod 7 one by one. Therefore, by controlling the extension and contraction of the detection rod 7 by the cylinder 10, the small ceramic pieces 5 can be perforated and tested for their quality.

[0027] A clearance hole 8 is defined in the center of the tray 4, allowing the insertion of a detection rod 7. The diameter of the clearance hole 8 should be larger than the through-hole at the center of the small ceramic component 5, while the diameter of the detection rod 7 should be smaller than the through-hole at the center of the small ceramic component 5. During perforation testing, the detection rod 7 does not need to be perfectly aligned with the through-hole; it only needs to be able to be inserted to detect blockage. Therefore, the diameter of the detection rod 7 can be slightly smaller; even a slight deviation will not affect the detection results of through-hole blockage.

[0028] A connecting arm 14 is hinged to the side of the cylinder 10 .

[0029] The stamping table 6 is provided with a mounting groove on the side facing the conveying table 2. The inner walls on both sides of the upper half of the mounting groove are installed with extension brackets 12. The two ends of the extension brackets 12 are respectively hinged with connecting rods 11. The lower ends of the four connecting rods 11 are hinged to the four corners of the same mounting block 13. A through opening 15 is provided inside the mounting block 13, and the lower end of the connecting arm 14 is rotatably connected to the through opening 15 through a connecting shaft.

[0030] The mounting block 13 is parallel to the surface of the conveying table 2 and a pushing column 16 is provided at the front end thereof for pushing the small ceramic piece 5 to slide.

[0031] The extension brackets 12 are all parallel to the table surface of the conveyor table 2, and the four connecting rods 11 are all parallel to each other. Under such a design, a deformable parallelogram structure is formed between the upper extension bracket 12, the two connecting rods 11 and the lower mounting block 13.

[0032] For small ceramic parts 5 that fail the inspection, the hydraulic lifting platform 9 will be lifted under the control of the hydraulic pressure, and the mounting block 13 will move forward horizontally due to the pulling action of the connecting arm 14. Finally, the pushing column 16 at the front end of the mounting block 13 will be used to push the unqualified products to the unloading platform 3 and slide them out.

[0033] Finally, it should be noted that the height of the cylinder 10 can be adjusted as the hydraulic lifting platform 9 is raised and lowered. The changes in the raising and lowering of the cylinder 10 are to control the advancement or retreat of the push column 16; and the extension and retraction of the detection straight rod 7 at the bottom of the cylinder 10 is used to detect whether the small ceramic piece 5 is qualified. The two processes do not affect each other.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
