[0029] Referring to Figure 5 and Figure 6 , the lower part of the pressing plate 100 is a camera module workpiece. During long-term use, the pressing plate 100 will produce horizontal tilt, so that the pressing plate 100 is in a non-horizontal state. After the pressing plate 100 produces horizontal tilt, it will affect the pressing and positioning effect of the workpiece by the pressing plate 100. Therefore, it is necessary to regularly level the pressing plate 100. It is difficult to judge whether the pressing plate 100 is adjusted to a horizontal state by artificial naked eye observation, so a lot of time is spent on leveling, and the leveling efficiency is low.

[0030] It can be understood that, referring to Figures 1 to 4The utility model discloses a kind of pressing plate 100 leveling mechanism, including pressing plate 100, leveling assembly 200 and measuring assembly 300, leveling assembly 200, including connecting block 210, first adjusting block 220, second adjusting block 230, first pivot 240, second pivot 250, two first adjusting bolts 260 and two second adjusting bolts 270, first adjusting block 220 is rotatably connected in connecting block 210 by first pivot 240, second adjusting block 230 is rotatably connected in first adjusting block 220 by second pivot 250, the axis of first pivot 240 and second pivot 250 is vertically arranged along horizontal direction, pressing plate 100 is connected in second adjusting block 230, first adjusting bolt 260 is threadedly connected in first adjusting block 220, two first adjusting bolts 260 are respectively arranged in the radial opposite sides of first pivot 240, the lower end of first adjusting bolt 260 abuts connecting block 210, second adjusting bolt 270 is threadedly connected in second adjusting block 230, two second adjusting bolts 270 are respectively arranged in the radial opposite sides of second pivot 250, the lower end of second adjusting bolt 270 abuts first adjusting block 220;Measuring assembly 300 includes support seat 310, first level 320 and second level 330, first level 320 is arranged in support seat 310 along the axial direction of second pivot 250, second level 330 is arranged in support seat 310 along the axial direction of first pivot 240, support seat 310 is connected in pressing plate 100.

[0031] Since first adjusting block 220 is rotatably connected in connecting block 210 by first pivot 240, second adjusting block 230 is rotatably connected in first adjusting block 220 by second pivot 250, pressing plate 100 is connected in second adjusting block 230, so that first adjusting block 220 can drive second adjusting block 230 and pressing plate 100 to rotate around the axis of first pivot 240, second adjusting block 230 can drive pressing plate 100 to rotate around the axis of second pivot 250, since the axis of first pivot 240 and second pivot 250 is vertically arranged along horizontal direction, the rotating direction of first adjusting block 220 and second adjusting block 230 is perpendicular to each other, and pressing plate 100 can be adjusted to horizontal position from two horizontal and vertical directions respectively, when pressing plate 100 is adjusted to horizontal position, by tightening first adjusting bolt 260 on the radial opposite sides of first pivot 240, the lower end of two first adjusting bolts 260 abuts connecting block 210, to limit the rotation of first adjusting block 220, and by tightening second adjusting bolt 270 on the radial opposite sides of second pivot, the lower end of two second adjusting bolts 270 abuts first adjusting block 220, to limit the rotation of second adjusting block 230, so as to position the position of pressing plate 100, and whether pressing plate 100 is adjusted to horizontal state is observed by first level 320 and second level 330, the state of adjustment can be judged intuitively, so as to improve the convenience and efficiency of leveling of pressing plate 100.

[0032] Since the first level 320 is arranged on the support base 310 along the axial direction of the second rotating shaft 250, the rotation of the first adjusting block 220 is observed by the first level 320 to determine whether the presser plate 100 is adjusted to the horizontal position. Since the second level 330 is arranged on the support base 310 along the axial direction of the first rotating shaft 240, the rotation of the second adjusting block 230 is observed by the second level 330 to determine whether the presser plate 100 is adjusted to the horizontal position.

[0033] It should be noted that, referring to Figure 5 When the presser plate 100 is tilted and raised along the axial direction of the second rotating shaft 250, the first adjusting bolt 260 on the raised side is screwed upward to generate a gap between the lower end of the first adjusting bolt 260 and the connecting block 210, so as to provide a rotating space for the first adjusting block 220, until the presser plate 100 is adjusted to the horizontal position. Then, the first adjusting bolt 260 on the other side is screwed downward, so that the two first adjusting bolts 260 abut against the connecting block 210 at the same time, so as to limit the rotation of the first adjusting block 220, thereby positioning the position of the presser plate 100.

[0034] Referring to Figure 6 When the presser plate 100 is tilted and raised along the axial direction of the first rotating shaft 240, the second adjusting bolt 270 on the raised side is screwed upward to generate a gap between the lower end of the second adjusting bolt 270 and the first adjusting block 220, so as to provide a rotating space for the second adjusting block 230, until the presser plate 100 is adjusted to the horizontal position. Then, the second adjusting bolt 270 on the other side is screwed downward, so that the two second adjusting bolts 270 abut against the first adjusting block 220 at the same time, so as to limit the rotation of the second adjusting block 230, thereby positioning the position of the presser plate 100.

[0035] The first level 320 and the second level 330 can be a bubble level or an electronic level, etc., which can directly observe whether the presser plate 100 is in the horizontal state.

[0036] The first rotating shaft 240 and the second rotating shaft 250 can be provided with smooth sections and threaded sections. The first adjusting block 220 is rotatably connected to the smooth section of the first rotating shaft 240, and the threaded section of the first rotating shaft 240 is threadedly connected to the connecting block 210, so as to fix the first rotating shaft 240 to the connecting block 210. The first adjusting block 220 is rotatably connected to the smooth section of the second rotating shaft 250, and the threaded section of the second rotating shaft 250 is threadedly connected to the second adjusting block 230, so as to fix the second rotating shaft 250 to the second adjusting block 230.

[0037] It should be noted that, referring to Figures 1 to 3The lower end of the support base 310 is provided with a clamping groove 311, and the pressing plate 100 can be clamped into the clamping groove 311. By clamping the pressing plate 100 into the clamping groove 311, the support base 310 can be connected to the pressing plate 100, and the support base 310 can be conveniently disassembled. In addition, when the pressing plate 100 is adjusted to a horizontal state, the support base 310 can be disassembled from the pressing plate 100, so as to reduce the influence on the pressing plate 100.

[0038] Specifically, referring to Figure 2 and Figure 3 , the shape of the clamping groove 311 matches the shape of the pressing plate 100. Since the shape of the clamping groove 311 matches the shape of the pressing plate 100, when the pressing plate 100 is clamped into the clamping groove 311, the pressing plate 100 can tightly adhere to the inner wall of the clamping groove 311 to position the support base 310, so as to reduce the position shaking of the support base 310, improve the detection accuracy of the first level meter 320 and the second level meter 330, and thus improve the leveling accuracy.

[0039] Specifically, referring to Figure 2 and Figure 3 , the top surface of the clamping groove 311 is provided with a magnetic block 340, and the magnetic block 340 can magnetically attract the pressing plate 100. By magnetically attracting the pressing plate 100 through the magnetic block 340 to position the support base 310, the position shaking of the support base 310 can be reduced, the detection accuracy of the first level meter 320 and the second level meter 330 can be improved, and thus the leveling accuracy can be improved. In addition, the magnetic positioning method can facilitate the disassembly of the support base 310.

[0040] It should be noted that the magnetic block 340 can be a permanent magnet or an electromagnet, which can magnetically attract the pressing plate 100. The pressing plate 100 can be a magnetic part made of stainless steel or iron.

[0041] Specifically, referring to Figure 3 , the top surface of the clamping groove 311 is provided with a mounting groove 312, and the magnetic block 340 is clamped into the mounting groove 312. By clamping the magnetic block 340 into the mounting groove 312, the assembly between the magnetic block 340 and the support base 310 can be realized, and the assembly convenience can be improved.

[0042] It should be noted that when the magnetic block 340 is clamped into the mounting groove 312, the lower end surface of the magnetic block 340 can be flush with the top surface of the clamping groove 311, so that the upper end surface of the pressing plate 100 can tightly adhere to the top surface of the clamping groove 311, and the possibility of horizontal tilting of the support base 310 can be reduced, thereby improving the leveling accuracy.

[0043] Specifically, referring to Figure 1 and Figure 2The support base 310 is threadedly connected with a positioning bolt 350, the positioning bolt 350 is arranged along the axial direction of the first rotating shaft 240, and the end of the positioning bolt 350 can extend into the clamping groove 311 and abut against the pressing plate 100. Since the support base 310 is threadedly connected with the positioning bolt 350, by tightening the positioning bolt 350, the end of the positioning bolt 350 extends into the clamping groove 311 and abuts against the pressing plate 100, so as to fix the position of the support base 310, the position of the support base 310 can be reduced to shake, and the detection accuracy of the first level meter 320 and the second level meter 330 is improved, so as to improve the leveling accuracy.

[0044] It can be understood that, with reference to Figure 2 、 Figure 3 and Figure 5 , the leveling assembly 200 further comprises two first elastic members 280, the two ends of the first elastic member 280 abut against the connecting block 210 and the first adjusting block 220 respectively, the first elastic member 280 is used for driving the first adjusting block 220 to rotate in a direction away from the connecting block 210, and the two first elastic members 280 are arranged on the diametrically opposite sides of the first rotating shaft 240. When the pressing plate 100 is tilted horizontally and rises along the axial direction of the second rotating shaft 250, the first elastic member 280 on the sagging side is compressed and deformed, the first adjusting bolt 260 on the rising side is screwed upward, a gap is generated between the lower end of the first adjusting bolt 260 and the connecting block 210, and the first adjusting block 220 is driven to rotate in a direction away from the connecting block 210 by the elastic restoring force generated by the first elastic member 280 on the sagging side, so that the first adjusting bolt 260 on the rising side abuts against the connecting block 210 during the screwing process, a gap is generated between the first adjusting bolt 260 on the sagging side and the connecting block 210, the adjusting state can be observed in real time, the possibility that the leveling state is affected by the rotation of the first adjusting block 220 is reduced, and the convenience and efficiency of leveling are improved. When the pressing plate 100 is adjusted to a horizontal state, the first adjusting bolt 260 on the sagging side is screwed downward until the first adjusting bolt 260 abuts against the connecting block 210, so as to limit the rotation of the first adjusting block 220, thereby positioning the position of the pressing plate 100.

[0045] It should be noted that the first elastic member 280 can be a spring or a spring sheet, which can be elastically deformed to drive the first adjusting block 220 to rotate in a direction away from the connecting block 210.

[0046] Specifically, with reference to Figure 3The side of the connecting block 210 and the first adjusting block 220 facing each other is provided with a vertical positioning slot 211, and the two ends of the first elastic member 280 are respectively clamped into the two positioning slots 211. By clamping the two ends of the first elastic member 280 into the two positioning slots 211, the radial position of the first elastic member 280 can be positioned, and the first elastic member 280 is guided to deform in the vertical direction, so as to reduce the possibility of position deviation of the first elastic member 280.

[0047] It can be understood that, referring to Figure 2 、 Figure 4 and Figure 6 , the leveling assembly 200 further comprises two second elastic members 290, the two ends of the second elastic member 290 respectively abut against the first adjusting block 220 and the second adjusting block 230, the second elastic member 290 is used to drive the second adjusting block 230 to rotate away from the first adjusting block 220, and the two second elastic members 290 are respectively arranged on the diametrically opposite sides of the second rotating shaft 250. When the pressing plate 100 is tilted horizontally and lifted along the axial direction of the first rotating shaft 240, the second elastic member 290 on the drooping side is compressed and deformed, the second adjusting bolt 270 on the lifting side is screwed upward, a gap is generated between the lower end of the second adjusting bolt 270 and the first adjusting block 220, and at the same time, the second adjusting block 230 is driven to rotate away from the first adjusting block 220 by the elastic restoring force generated by the second elastic member 290 on the drooping side, so that the second adjusting bolt 270 on the lifting side always abuts against the first adjusting block 220 during the screwing process, and a gap is generated between the second adjusting bolt 270 on the drooping side and the first adjusting block 220, so that the adjusting state can be observed in real time, and the possibility of affecting the leveling state judgment due to the rotation of the second adjusting block 230 is reduced, so as to improve the convenience and efficiency of leveling. When the pressing plate 100 is adjusted to a horizontal state, the second adjusting bolt 270 on the drooping side is screwed downward until the second adjusting bolt 270 abuts against the first adjusting block 220, so as to limit the rotation of the second adjusting block 230, thereby positioning the position of the pressing plate 100.

[0048] It should be noted that the second elastic member 290 can be a spring or a spring sheet, which can be elastically deformed to drive the second adjusting block 230 to rotate away from the first adjusting block 220.

[0049] It can be understood that, referring to Figures 1 to 3 , the pressing plate 100 is provided with a fixing bolt 400, and the fixing bolt 400 is threadedly connected to the second adjusting block 230. The pressing plate 100 is fixedly connected to the second adjusting block 230 through the fixing bolt 400, so that the pressing plate 100 can be conveniently disassembled and replaced.
