Detailed implementation manners

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0024] As Figures 1 - 5 shown, a placement rack for cleaning a ceramic substrate proposed in an embodiment of the present application includes:

[0025] Two side plates, both of which are in the vertical direction and spaced apart. The side plates include a first adjusting plate 1 and a second adjusting plate 2 that are slidably connected. The first adjusting plate 1 and the second adjusting plate 2 are slidably connected in the horizontal direction. A locking rod 3 is hinged on the first adjusting plate 1, and a torsion spring 4 is arranged between them. The torsion spring 4 is in the horizontal direction and is fixed at the hinge of the locking rod 3. A limiting member that acts on the locking rod 3 and limits it is arranged on the second adjusting plate 2;

[0026] Two connecting rods 5 and two groups of cross bars 6 are respectively arranged between the two first adjusting plates 1 and the two second adjusting plates 2. The connecting rods 5 and the cross bars 6 are both in the horizontal direction and perpendicularly distributed. The connecting rods 5 are fixed between the two first adjusting plates 1 or the two second adjusting plates 2. The number of each group of cross bars 6 is two and they are distributed vertically. A plurality of rollers 7 are rotatably arranged on the cross bars 6. The plurality of rollers 7 are all in the vertical direction and are arranged in an array along the length direction of the cross bars 6. A circumferential groove 8 is formed on the rollers 7, and the circumferential groove 8 is used for the side of the ceramic substrate to be inserted;

[0027] In the initial state, the locking rod 3 is in the vertical direction, the torsion spring 4 is in the natural state, the locking rod 3 is limited by the limiting member, and the first adjusting plate 1 and the second adjusting plate 2 cannot slide relative to each other. When in use, the ceramic substrate is in the vertical direction and its side is inserted into the circumferential groove 8. The ceramic substrate is in contact and lapped with both connecting rods 5. Through the cooperation of the circumferential groove 8 and the connecting rods 5, the vertical state of the ceramic substrate is maintained, and the ceramic substrate and the side plate are parallelly distributed, so as to place the ceramic substrate on the placing rack. Since the roller 7 is rotatably arranged on the cross bar 6, the friction when the side of the ceramic substrate is inserted into the circumferential groove 8 can be reduced, and the side of the ceramic substrate can be prevented from being worn due to excessive friction. Then, the cleaning process can be carried out. The locking rod 3 can be driven to rotate to a direction close to the horizontal direction, the torsion spring 4 is compressed, and the first adjusting plate 1 and the second adjusting plate 2 can slide relative to each other, so as to adjust the length between the first adjusting plate 1 and the second adjusting plate 2. Then, the locking rod 3 is released, the torsion spring 4 returns to the natural state, the locking rod 3 rotates to the vertical direction, and the locking rod 3 is limited by the limiting member, and the first adjusting plate 1 and the second adjusting plate 2 cannot slide relative to each other, so as to be applicable to ceramic substrates of different widths and improve the use flexibility and applicability;

[0028] In summary, when in use, the length between the first adjusting plate 1 and the second adjusting plate 2 can be adjusted in the present application, so as to be applicable to ceramic substrates of different widths and improve the use flexibility and applicability. Therefore, it is more practical.

[0029] As Figure 2 shown, in some embodiments, the limiting member includes a fixed rod 9 arranged on the second adjusting plate 2. The fixed rod 9 is in the horizontal direction and is fixed on the second adjusting plate 2. A plurality of clamping grooves 10 are formed on the fixed rod 9, and the plurality of clamping grooves 10 are arranged in an array along the length direction of the fixed rod 9. The locking rod 3 is in plug-in fit with the clamping grooves 10;

[0030] Referring to the above, in the initial state, the locking rod 3 is in the vertical direction and is inserted into one of the clamping grooves 10, and the torsion spring 4 is in the natural state. Due to the elastic potential energy of the torsion spring 4, the locking rod 3 cannot withdraw from the clamping groove 10 to realize the limitation of the locking rod 3, and the first adjusting plate 1 and the second adjusting plate 2 cannot slide relative to each other. On the contrary, when the locking rod 3 is driven to rotate to a direction close to the horizontal direction, the locking rod 3 withdraws from the clamping groove 10, the torsion spring 4 is compressed, and the first adjusting plate 1 and the second adjusting plate 2 can slide relative to each other. Then, the locking rod 3 is released, the torsion spring 4 returns to the natural state, and the locking rod 3 rotates to the vertical direction and is inserted into one of the clamping grooves 10, so as to limit the locking rod 3.

[0031] As Figure 5 shown, in some embodiments, the cross-sectional structure of the circumferential groove 8 is an isosceles trapezoid;

[0032] Referring to the above, when the side of the ceramic substrate is inserted into the circumferential groove 8, due to the cross-sectional structure of the circumferential groove 8 being isosceles trapezoidal, it is possible to prevent the side of the ceramic substrate from contacting the circumferential groove 8, thereby avoiding wear on the side of the ceramic substrate. At the same time, it is also beneficial for the cleaning liquid to come into full contact with the ceramic substrate, improving the cleaning effect.

[0033] As Figure 5 shown, in some embodiments, a plurality of through holes 11 communicating with the circumferential groove 8 are formed on the roller 7, and the plurality of through holes 11 are annularly arrayed around the axis of the circumferential groove 8;

[0034] Referring to the above, during use, due to the arrangement of the plurality of through holes 11, it is beneficial for the cleaning liquid to come into full contact with the ceramic substrate, further improving the cleaning effect.

[0035] As Figure 5 shown, in some embodiments, annular grooves 12 corresponding to the rollers 7 in number and one-to-one are formed on the cross bar 6, and the plurality of annular grooves 12 are all in the vertical direction and arrayed along the length direction of the cross bar 6. Annular protrusions 13 that are rotationally matched with the annular grooves 12 are provided on the rollers 7. The annular protrusions 13 are in the vertical direction and are fixedly arranged on the rollers 7, and the annular protrusions 13 are completely located within the annular grooves 12;

[0036] Referring to the above, when the roller 7 rotates, it drives the annular protrusions 13 to rotate together within the annular grooves 12. Through the cooperation of the annular protrusions 13 and the annular grooves 12, the roller 7 is limited, preventing the roller 7 from shifting, thereby improving the use stability.

[0037] As Figures 3 - 4 shown, in some embodiments, the lower cross bar 6 is a bottom bar and is fixedly arranged between two first adjusting plates 1 or two second adjusting plates 2. The first adjusting plates 1 and the second adjusting plates 2 are both provided with the same number and a plurality of positioning grooves 14 and fixing blocks 15. The positioning grooves 14 are in the horizontal direction, and the fixing blocks 15 are fixedly arranged on the first adjusting plates 1 or the second adjusting plates 2. The upper cross bar 6 is a top bar and is inserted and matched with the positioning grooves 14. A limiting portion is provided on the top bar for axially limiting the top bar. Here, the axial limiting means preventing the top bar from moving along its axis direction. A locking member that acts on the top bar and laterally limits or releases the limit is provided on the fixing block 15;

[0038] Referring to the above, in the initial state, both ends of the ejector rod are respectively located in the two positioning grooves 14. The axial position of the ejector rod is limited by the limiting portion, and the lateral position of the ejector rod is limited by the locking member. The ejector rod cannot move along its axial direction and cannot exit the positioning groove 14. The limiting of the ejector rod can be released through the locking member, so that the ejector rod moves horizontally to exit the positioning groove 14 to realize the disassembly of the ejector rod. After that, the height position of the ejector rod can be adjusted so that both ends of the ejector rod are respectively located in the two positioning grooves 14. The axial position of the ejector rod is limited by the limiting portion, and the lateral position of the ejector rod is limited by the locking member to realize the adjustment of the distance between the bottom rod and the ejector rod, so as to be applicable to ceramic substrates of different lengths and further improve the use flexibility and applicability.

[0039] As Figure 4 shown, in some embodiments, the limiting portion includes two limiting rings 16 both provided on the ejector rod. The limiting rings 16 are in the vertical direction and are fixed on the ejector rod. The two limiting rings 16 are spaced apart. The limiting rings 16 are in contact and overlap with the first adjusting plate 1 or the second adjusting plate 2.

[0040] Referring to the above, in the initial state, the two limiting rings 16 are respectively in contact and overlap with the two first adjusting plates 1 or the two second adjusting plates 2. Due to the blocking of the two limiting rings 16, the ejector rod cannot move along its axial direction to realize the axial limiting of the ejector rod. When the ejector rod is disassembled, the two limiting rings 16 are respectively away from the two first adjusting plates 1 or the two second adjusting plates 2.

[0041] As Figure 3 shown, in some embodiments, the locking member includes a limiting slide rod 17 slidably disposed on the fixed block 15. The limiting slide rod 17 slides in the vertical direction. A wedge block 18 in contact and overlap with the ejector rod is provided at the free end of the limiting slide rod 17. The wedge block 18 is in the vertical direction and is fixed at the free end of the limiting slide rod 17. An extrusion spring 19 sleeved on the limiting slide rod 17 is provided between the wedge block 18 and the fixed block 15. The extrusion spring 19 is in the vertical direction and is fixedly connected to the wedge block 18 and the fixed block 15 at both ends respectively.

[0042] Referring to the above, in the initial state, the compression spring 19 is in a natural state, the limit slide bar 17 and the wedge block 18 are both located at the initial positions, the plane of the wedge block 18 abuts and overlaps with the ejector rod. Due to the blockage of the wedge block 18, the ejector rod cannot withdraw from the positioning groove 14, so as to realize the lateral limit of the ejector rod. When the ejector rod is disassembled, the limit slide bar 17 is driven to slide downward to the limit position, driving the wedge block 18 to move away from the ejector rod together. The compression spring 19 is compressed. Due to the loss of the blockage of the wedge block 18, the ejector rod can withdraw from the positioning groove 14, so as to release the limit of the ejector rod. Then the limit slide bar 17 is released, and the compression spring 19 returns to the natural state. The limit slide bar 17 and the wedge block 18 move upward to the initial positions together. On the contrary, when the ejector rod enters the positioning groove 14, it first abuts and overlaps with the inclined surface of the wedge block 18. Through the transition effect of the inclined surface, the wedge block 18 and the limit slide bar 17 are forced to move downward to the limit position together, and the compression spring 19 is compressed. Then the compression spring 19 returns to the natural state, and the limit slide bar 17 and the wedge block 18 move upward to the initial positions together, so as to realize the lateral limit of the ejector rod.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
