Therefore, these directional terms are intended to illustrate and facilitate understanding of this disclosure and are not intended to limit this disclosure. Furthermore, in the accompanying drawings, similar or identical structures are denoted by the same reference numerals.
[0034] Reference Figures 1 to 8 , which shows an embodiment of the heating plate lifting base 100 provided by the present invention. The structure and working principle of the heating plate lifting base 100 are described in detail below in conjunction with the drawings in the specification. The heating plate lifting base 100 includes a base 10, an adjustment block 30, a mounting seat 20 and a first adjustment member 40; the adjustment block 30 is arranged on the base 10, and a plurality of first adjustment holes 301 are arranged around the upper side of the adjustment block 30; the mounting seat 20 is arranged on the adjustment block 30 for mounting the heating plate 300; a plurality of first adjustment members 40 are respectively arranged around the mounting seat 20 and cooperate with the first adjustment holes 301, wherein the first adjustment member 40 is used to move along the height direction of the first adjustment hole 301 to drive the mounting seat 20 to adjust its levelness.
[0035] In a specific implementation, the heating plate lifting base 100 is mainly used in thin film deposition equipment and is used to connect the lifting module 200 of the thin film deposition equipment. The heating plate lifting base 100 includes a base 10, an adjustment block 30, a mounting base 20, and a first adjustment member 40. The base 10 is directly connected to the lifting module 200 of the thin film deposition equipment, and the lifting module 200 of the thin film deposition equipment can directly drive the base 10 to move up and down. The adjustment block 30 is entirely arranged on the base 10 and can move horizontally relative to the base 10. A plurality of first adjustment holes 301 are distributed around the upper side of the adjustment block 30. The first adjustment holes 301 have a certain depth. The specific number of the first adjustment holes 301 is not limited and can be designed to be three or more. For example, when three first adjustment holes 301 are designed, the three first adjustment holes 301 can form a triangular distribution structure on the upper side of the adjustment block 30. The mounting base 20 is entirely arranged on the base 10 and is mainly used to mount the heating plate 300. The mounting base 20 is provided with a corresponding connection structure to connect and fix the heating plate 300. There are multiple first adjustment members 40, and the number of first adjustment members 40 corresponds to the number of first adjustment holes 301. Multiple first adjustment members 40 are respectively arranged around the mounting base 20 and cooperate with the first adjustment holes 301. The first adjustment members 40 and the first adjustment holes 301 can be matched by threaded matching or other matching methods, which are not limited here. When the first adjustment members 40 cooperate with the first adjustment holes 301, the first adjustment members 40 move along the height direction of the first adjustment holes. The movement of the first adjustment members 40 will cause the height of the corresponding position of the mounting base 20 to change. Each first adjustment member 40 corresponds to a first adjustment hole 301. By each first adjustment member 40 moving along the height direction of the corresponding first adjustment hole 301, the height of the surrounding position of the mounting base 20 will change, thereby adjusting the horizontality of the surrounding area of the mounting base 20. The heating plate 300 is mounted on the mounting base, and the levelness of the mounting base 20 corresponds to the levelness of the heating plate 300. By adjusting the levelness of the surrounding areas of the mounting base 20, the levelness of the heating plate 300 can be adjusted, and the heating plate 300 can be easily adjusted to a horizontal state. In actual application, when the heating plate 300 needs to be adjusted to a horizontal state, the level of the heating plate 300 is observed, and the distance the first adjusting member 40 moves along the height direction of the first adjusting hole 301 is adjusted according to the vertical deviation of the heating plate 300. When the heating plate 300 deviates downward in the direction where a first adjusting member 40 is located, the first adjusting member 40 is adjusted to move upward along the height direction of the first adjusting hole 301, and the remaining first adjusting members 40 are also adjusted to move downward along the height direction of the first adjusting hole 301. By observing the overall horizontal deviation of the heating plate 300 and adjusting the first adjusting members 40, the heating plate 300 can be easily and accurately adjusted to a horizontal state.
[0036] The heating plate lifting base of this embodiment sets the adjustment block on the base, and sets the mounting base used to connect the heating plate on the adjustment block. First adjustment holes are set around the upper side of the adjustment block, and multiple first adjustment parts are respectively set around the mounting base to cooperate with the first adjustment holes. The first adjustment parts are moved along the height direction of the first adjustment holes to drive the four sides of the mounting base to adjust its level, so the adjustment accuracy is higher and the reliability is better.
[0037] In one embodiment, referring to Figure 4 The first adjusting member 40 is a bolt, the first adjusting hole 301 is a screw hole, and the mounting base 20 is provided with a plurality of first screw holes 201 passing through the upper and lower sides thereof. The first screw holes 201 are vertically overlapped and aligned with the first adjusting hole 301, and the first adjusting member 40 is passed through the first screw holes 201 and the first adjusting hole 301. In the specific implementation, the first adjusting member 40 and the first adjusting hole 301 are threadedly matched. The first adjusting member 40 is designed as a bolt with a certain length, and the first adjusting hole is designed as a screw hole with a certain depth. A plurality of first screw holes 201 are arranged around the mounting base 20. The first screw holes 201 pass through the upper and lower sides of the mounting base 20. The number of first screw holes 201 corresponds to the number of first adjustment holes 301 one by one, and each first screw hole 201 on the mounting base 20 is distributed the same as each first adjustment hole 301 around the adjusting block 30. Each first screw hole 201 on the mounting base 20 and each first adjustment hole 301 around the adjusting block 30 maintain overlapping alignment in the vertical direction, and the first adjusting member 40 as a whole is passed through the first screw hole 201 and the first adjustment hole 301 and is threadedly connected to the two. During assembly, the first adjusting member 40 is first screwed into the first screw hole 201 on the mounting base 20. After the first adjusting member 40 passes through the first screw hole 201, it is screwed into the first adjusting hole 301 on the adjusting block 30 to complete the threaded connection. In actual application, when adjusting the balance state of the heating plate 300, each first adjusting member 40 is first screwed into each first screw hole 201 around the mounting base 20, so that the first adjusting member 40 extends a certain length from the first screw hole 201. By observing the horizontality of the upper heating plate 300, the heating plate 300 is kept horizontal. Then, all the first adjusting members 40 are rotated so that all the first adjusting members 40 are screwed into the first adjusting holes 301 on the adjusting block 30. In this way, the heating plate 300 always remains horizontal until all the first adjusting members 40 are tightened. As a result, the heating plate 300 can be easily and accurately adjusted to a horizontal state as a whole.
[0038] Further, refer to Figures 1 to 4The base 10 is provided with a vertically extending connecting port 202, the connecting port 202 is used for connecting the heating disc 300, and a plurality of first screw holes 201 are arranged around the circumference of the connecting port 202. In the specific implementation, the vertically extending connecting port 202 is arranged on the base 10, and the connecting port 202 is mainly used for connecting the heating disc 300. The bottom end of the heating disc 300 can be inserted into the connecting port 202 to complete the connection. After the heating disc 300 is connected to the connecting port 202, the installation seat 20 is installed to form an integral whole. All the first screw holes 201 are arranged around the circumference of the connecting port 202, and all the first screw holes 201 are distributed at intervals on the circumference of the connecting port 202. The connecting port 202 is located in the area surrounded by all the first screw holes 201. After the connecting disc is connected to the connecting port 202, the first screw holes 201 surround the bottom of the heating disc 300, so that the center of gravity of the heating disc 300 is closer to the horizontal adjustment center. During the horizontal adjustment process, the swing range of the heating disc 300 is small, and the heating disc 300 can be more easily adjusted to a horizontal state.
[0039] In an embodiment, with reference to Figures 1 to 4 The bottom of the installation seat 20 is provided with a spherical convex surface portion 21, the upper side of the adjusting block 30 is recessed with a spherical groove 31, a plurality of first adjusting holes 301 are arranged around the circumference of the spherical groove 31, and the spherical convex surface portion 21 is accommodated in the spherical groove 31 and can rotate relative to the spherical groove 31. In the specific implementation, the spherical convex surface portion 21 is protruded on the bottom of the installation seat 20. The outer side wall of the spherical convex surface portion 21 is a spherical curved surface and has a certain smoothness. The upper side of the adjusting block 30 is recessed with the spherical groove 31, the groove wall of the spherical groove 31 is a spherical curved surface, all the first adjusting holes 301 are arranged around the circumference of the spherical groove 31, and the spherical convex surface portion 21 is accommodated in the spherical groove 31 as a whole. The spherical curved surface on the outer side of the spherical convex surface portion 21 is matched with the spherical curved surface of the groove wall of the spherical groove 31. The outer side wall of the spherical convex surface portion 21 can be attached to the groove wall of the spherical groove 31. After the spherical convex surface portion 21 is accommodated in the spherical groove 31, the spherical convex surface portion 21 can rotate relative to the spherical groove 31. In actual application, when the heating disc 300 is adjusted to a balanced state, the installation seat 20 as a whole can rotate in any direction relative to the adjusting block 30. The position adjustment of the installation seat 20 is more relaxed, and the leveling of the heating disc 300 is more convenient.
[0040] In one embodiment, there are three first adjustment holes 301, and the distances between the axes of the three first adjustment holes 301 are equal. In a specific implementation, the number of first adjustment holes 301 is set to three, and the distances between the axes of the three first adjustment holes 301 are equal, that is, among the three first adjustment holes 301, the distances from the axis of any one first adjustment hole 301 to the axes of the other two first adjustment holes 301 remain equal, and the axis lines connecting the three first axis holes form an equilateral triangle. The number of first adjustment members 40 is set to three according to the number of first adjustment holes 301. In actual application, the three first adjustment members 40 are respectively provided at three locations around the mounting base 20 and are threadedly connected to the three screw holes. Since the distances between the axes of the three first adjustment holes 301 are equal, a position adjustment in the form of an equilateral triangle is formed. Tightening or unscrewing each first adjustment member 40 in the first adjustment hole 301 can cause the heating plate 300 to produce the same offset, making adjustment more precise and convenient.
[0041] In one embodiment, referring to Figures 1 to 8The heating plate lifting base 100 further includes a second adjustment member 50. The bottom of the adjustment block 30 extends downwardly and is provided with a plurality of support portions 32 distributed around the four sides of the base 10. The second adjustment member 50 is provided on the support portion 32 and cooperates with the four sides of the base 10. The second adjustment member 50 is used to drive the support portion to move horizontally closer to or away from the four sides of the base 10 to adjust the horizontal position of the adjustment block 30. In a specific implementation, the heating plate lifting base 100 further includes a second adjustment member 50. The bottom of the adjustment block 30 extends downwardly and is provided with a plurality of support portions 32. The plurality of support portions 32 are distributed around the four sides of the base 10 in the horizontal direction. The base 10 is located as a whole between the plurality of support portions 32. The specific number of support portions 32 can be set to three or more. Each second adjusting member 50 is provided on each supporting portion 32, and the second adjusting member 50 cooperates with the four sides of the base 10 in the horizontal direction respectively. The second adjusting member 50 drives the supporting portion 32 to approach or move away from the four sides of the base 10 in the horizontal direction by cooperating with the four sides of the base 10, so that the adjusting block 30 as a whole moves and changes its position relative to the base 10, thereby adjusting the horizontal position of the adjusting block 30. The second adjusting member 50 can cooperate with the four sides of the base 10 in the horizontal direction by extending into and pressing, or by other cooperation methods. In actual application, each second adjusting member 50 can drive each support portion 32 to approach or move away from a corresponding side of the four sides of the base 10. Multiple support portions 32 surround the four sides of the base 10. The second adjusting member 50 on one support portion 32 forms an adjustment in one direction, which can make the adjustment block 30 move in one direction. The second adjusting members 50 on all support portions 32 correspondingly form adjustments in multiple different directions. Through the cooperation of the second adjusting members 50 on multiple support portions 32 and the four sides of the base 10, the adjustment block 30 can be adjusted to any horizontal position, and the mounting base 20 is entirely arranged on the adjustment block 30. The heating plate 300 is connected to the mounting base 20. The heating plate 300 and the mounting base 20 will move with the movement of the adjustment block 30. Therefore, by adjusting the second adjusting member 50 on each support portion 32, the centering adjustment of the heating plate can be achieved. The adjustment is very convenient and the centering accuracy is high.
[0042] Further, refer to Figures 1 to 8The second adjusting member 50 is a bolt. The support portion 32 is provided with a second screw hole 302 extending laterally toward the base 10. The second adjusting member 50 is inserted into the second screw hole 302 and faces the four sides of the base 10. In a specific embodiment, the second adjusting member 50 is designed as a bolt. The support portion 32 is provided with a second screw hole 302 extending laterally toward the base 10. The second screw hole 302 laterally penetrates the inner and outer sides of the support portion 32. The number of second adjusting members 50 corresponds to the number of second screw holes 302. Each second adjusting member 50 is inserted into the second screw hole 302 on each support portion 32 and is threadedly connected thereto. The second adjusting member 50 is threadedly engaged with the second screw hole 302. The rear end of each second adjusting member 50 passing through the second screw hole 302 faces the corresponding side edge of the four sides of the base 10. The rear ends of all the second adjusting members 50 passing through the corresponding second screw holes 302 respectively face the four sides of the base 10. In actual application, the second adjusting member 50 is threadedly engaged with the second screw hole 302. By rotating the second adjusting member 50, the second adjusting member 50 can be advanced in the second screw hole 302, so that the second adjusting member 50 is extended toward the side of the base 10 relative to the support part 32. After the second adjusting member 50 is extended to a certain length, the end of the second adjusting member 50 will abut against the side of the base 10 in the horizontal direction. When the end of the second adjusting member 50 abuts against the side of the base 10 in the horizontal direction, the second adjusting member 50 is continued to be rotated and extended. Through the interaction of forces, the adjustment block 30 will move in the direction opposite to the direction in which the second adjusting member 50 is extended, thereby realizing the adjustment of the horizontal position of the adjustment block 30. In actual application, when adjusting the centering of the heating plate 300, by observing the centering of the heating plate 300 connected to the mounting seat 20, the corresponding second adjusting member 50 on the support part 32 is rotated, so that the second adjusting member 50 provided on all the supporting parts 32 extends toward the four sides of the base 10 and presses, so that the adjusting block 30 moves horizontally with the mounting seat 20 and the heating plate 300 until the heating plate 300 is adjusted to be centered. All the second adjusting members 50 are respectively abutted against the four sides of the base 10, and the positions of the adjusting block 30 and the mounting seat 20 remain fixed, so that the heating plate 300 always remains in the centered state. The entire centering adjustment is completed, and the centering adjustment of the heating plate 300 is very simple, convenient, accurate and reliable.
[0043] Further, refer to Figure 9 and Figure 10The base 10 is provided with a plurality of abutment surfaces 11 in the horizontal direction, each of the support portions 32 and each of the abutment surfaces 11 is spaced apart from each other, and the second adjustment member 50 is arranged perpendicular to the abutment surfaces 11. In a specific embodiment, the base 10 is provided with a plurality of abutment surfaces 11 in the horizontal direction, and the abutment surfaces 11 are planes on the outside of the base 10. Each of the support portions 32 and each of the abutment surfaces 11 is spaced apart from each other on the horizontal plane by a certain distance, and one support portion 32 corresponds to one abutment surface 11. The second adjustment member 50 is a bolt structure, and the second adjustment member 50 is arranged perpendicular to the abutment surfaces 11 as a whole, that is, the second adjustment member 50 remains perpendicular to the abutment surfaces 11 after passing through the second screw hole 302 on the support portion 32. When actually adjusting the centering of the heating plate 300, the second adjustment member 50 provided on each support portion 32 can be vertically abutted against a corresponding abutment surface 11. By rotating the second adjustment member 50, the second adjustment member 50 can be vertically pressed toward the abutment surface 11. The movement of the adjustment block 30 will not deviate, the centering adjustment can be more precise, and the state of the fixed heating plate 300 can be more stable.
[0044] Furthermore, the plurality of support portions 32 are evenly spaced around the base 10. Specifically, the support portions 32 are designed to be evenly spaced around the base 10, and the distance between two adjacent support portions 32 is equal, so that each second adjustment member 50 extends toward the base 10 by the same length, and the heating plate 300 is displaced by the same distance in the horizontal direction, making adjustment more precise and convenient.
[0045] Preferably, three of each of the support portions 32 and the abutment surfaces 11 are provided. In a specific embodiment, three of each of the support portions 32 and the abutment surfaces 11 are provided. The three support portions 32 are provided at the bottom of the adjustment block 30 around the base 10, and the three support portions 32 are equidistant from one another, forming an equilateral triangle. The three abutment surfaces 11 in the horizontal direction of the base 10 correspond one-to-one with the three support portions 32, respectively. The three second adjustment members 50 pass through the second screw holes 302 on the three support portions 32, respectively, and can vertically abut against the three abutment surfaces 11, thereby forming a three-directional centering adjustment. This makes actual adjustment simpler and provides high centering accuracy.
