[0024] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 and Figure 2 As shown, a ceramic plate flatness detection device includes a workbench 1, a positioning component 2, a detection frame 3 and a driving component 4. The upper surface of the workbench 1 is a flat working surface. The positioning component 2 is arranged on the upper surface of the workbench 1. The positioning component 2 includes a positioning stud 21, a positioning nut 22, a first cushion block 23 and a second cushion block 24. The lower end of the positioning stud 21 is connected to the upper surface of the workbench 1. When detecting, the ceramic plate 9 is placed horizontally. When the ceramic plate 9 is fired, a hole corresponding to the positioning stud 21 is reserved. The positioning stud 21 penetrates the ceramic plate 9 from the back of the ceramic plate. The first cushion block 23 is placed first and then the positioning stud 21 is placed. The ceramic plate 9 is placed, so that the first cushion block 23 is located between the ceramic plate 9 and the workbench 1. After the ceramic plate 9 is placed, the second cushion block 24 is placed, and then the positioning nut 22 is connected to the positioning stud 21. The positioning nut 22 is tightened to fix the ceramic plate 9. A plurality of holes for connecting with external equipment are reserved on the ceramic plate 9. A plurality of positioning studs 21 can be provided corresponding to these holes to stabilize the ceramic plate 9. The first cushion block 23 includes a plurality of first sub-cushions. The number of the first sub-cushions is adjusted to adjust the distance from the ceramic plate 9 to the upper surface of the workbench 1. The ceramic plate 9 is suspended by the positioning assembly 2.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, the detection frame 3 includes an outer frame 31 and a height adjustment rod 32. The outer frame 31 is a rectangular frame, including two side blocks 311, a first cross bar 312 and a second cross bar 313. The side blocks 311 are symmetrically arranged on both sides. The first cross bar 312 and the second cross bar 313 are both connected between the two side blocks 311. The first cross bar 312 is arranged at the top, and the second cross bar 313 is arranged at the bottom. The height of the second cross bar 313 corresponds to the height of the first cushion block 23. When the flatness requirement of the ceramic plate 9 is less than or equal to 1 mm, the height of the second cross bar 313 is 1 mm lower than the height of the first cushion block 23. The lower surface contacts the upper surface of the workbench 1 and can slide on the upper surface of the workbench 1. The upper surface of the second cross bar 313 is the second detection surface 302. When the driving component 4 pushes the detection frame 3 to move toward the ceramic plate 9, the second detection surface 302 moves under the back of the ceramic plate 9, so that the flatness of the back of the ceramic plate 9 can be detected. When part of the back of the ceramic plate 9 protrudes downward and causes the flatness to exceed the standard, the second cross bar 313 will be stuck by the back of the ceramic plate 9. At this time, it is judged that the flatness of this ceramic plate 9 is unqualified. The part of the back of the ceramic plate 9 that is concave inward does not belong to the flatness exceeding the standard, and it will not affect the movement of the second cross bar 313 under the back of the ceramic plate 9.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the height adjustment rod 32 is a transversely arranged rectangular rod, the height adjustment rod 32 is located between the two side blocks 311, and two symmetrically arranged height adjustment studs 33 are provided on the height adjustment rod 32. The height adjustment stud 33 passes through the first cross bar 312, and the first adjusting nut 34 and the second adjusting nut 35 are connected to the height adjustment stud 33. The first adjusting nut 34 is located above the first cross bar 312. Loosening or tightening the first adjusting nut 34 can fine-tune the height of the height adjustment rod 32. The second adjusting nut 35 is located between the first cross bar 312 and the height adjustment rod 32. When the height adjustment rod 32 is adjusted to a predetermined height, tightening the second adjusting nut 35 can fix the position of the height adjustment rod 32. The lower surface of the height adjustment rod 32 is the first detection surface 301. The height of the first detection surface 301 corresponds to the height of the upper surface of the ceramic plate 9. When the flatness requirement of the ceramic plate 9 is less than or equal to 1 mm, the height of the first detection surface 301 is 1 mm higher than the height of the upper surface of the ceramic plate 9. When the driving assembly 4 pushes the detection frame 3 to move toward the ceramic plate 9, the first detection surface 301 moves above the front of the ceramic plate, so that the flatness of the front of the ceramic plate 9 can be detected. When the front part of the ceramic plate 9 protrudes upward, resulting in excessive flatness, the height adjustment rod 32 will be blocked by the front of the ceramic plate 9. At this time, the flatness of the ceramic plate 9 is judged to be unqualified. The front part of the ceramic plate 9 is concave inward, which does not belong to excessive flatness, and it will not affect the movement of the height adjustment rod 32 above the front of the ceramic plate 9. The height of the height adjustment rod 32 can be adjusted, so it is suitable for ceramic plates with various thicknesses and flatness requirements. Scale marks 5 are provided on the two side blocks 311. The scale marks 5 correspond to the position of the height adjustment rod 32, so that when the height adjustment rod 32 is adjusted, the scale marks 5 can be used to make the two sides equal and determine the height.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, two drive components 4 are symmetrically arranged, and the drive component 4 is a cylinder. The cylinder adopts the existing pneumatic drive rod, and a Y-type joint 41 is provided on the top of the piston rod of the cylinder. Second joints 36 are provided on the two side blocks 311 of the detection frame 3, and the second joints 36 correspond to the Y-type joints 41. A second through hole is provided on the second joint 36, and a first through hole is provided on the Y-type joint 41. The first through hole and the second through hole are penetrated by connecting bolts 6, so as to connect the detection frame 3 with the drive component 4, and a buckle 61 is provided on the connecting bolt 6. After the connecting bolt 6 passes through the first through hole and the second through hole, the buckle 61 is clamped on the piston rod of the cylinder to prevent the connecting bolt 6 from falling off.

[0029] like Figure 1 , Figure 3 and Figure 4As shown, a first slope block 37 is provided on one side of the second cross bar 313 of the outer frame 31, and a second slope block 38 is provided on the other side. The first slope block 37 is located on the side close to the positioning component 2 and has a smaller slope, and the second slope block 38 is located on the side close to the driving component 4 and has a larger slope. The two slope blocks are integrally formed with the second cross bar 313, which can increase the lower surface area of ​​the second cross bar 313, thereby increasing the stability of the detection frame 3 when it moves on the upper surface of the workbench 1.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
