Description

TECHNICAL FIELD

[0001] The utility model relates to laser bonding process technical field, more specifically, it is a leveling device. BACKGROUND

[0002] In modern industrial manufacturing, especially in the field of jigs related to Micro led laser bonding process, the performance of the jig has a crucial influence on the process effect. In the prior art, there are serious problems in the preheating process of the jig. When the jig is preheated, heat will be conducted through the steel material. Due to the good thermal conductivity of the steel material, heat will be transferred from the jig to the remaining parts at the bottom. This heat transfer phenomenon will cause the temperature of the bottom parts to rise, thereby negatively affecting the precision and stability of the remaining parts and the entire structure. For example, temperature changes can cause thermal expansion of the bottom parts, change their original dimensional accuracy, damage the fit tolerance between structures, cause the equipment to deviate during operation, and reduce production efficiency and product quality.

[0003] In order to solve the problem of high heat transfer efficiency, a heat insulation device is provided between the jig and the bottom parts. Currently, some ordinary heat insulation materials such as plastic are considered to solve the heat transfer problem. However, these materials themselves have poor rigidity. In the application scenario of Micro led laser bonding process which requires high precision, the lack of rigidity of the jig will directly lead to poor precision and flatness. Specifically, the jig is prone to deformation when subjected to certain pressure or stress, which cannot guarantee the accurate position of micro elements such as Micro led chips during the bonding process, seriously affecting the process effect and reducing the yield of products.

[0004] Therefore, in order to reduce the heat transfer efficiency while ensuring the support strength between the jig and the bottom parts, the traditional method is to reduce the contact area of the heat insulation material and set multiple supports. However, due to the error in the processing of the support material, these errors cause the supports at different places to be at different levels, which destroys the flatness of the jig surface. Therefore, there is an urgent need for a new jig design scheme to solve the above problems. UTILITY MODEL CONTENTS

[0030] Reference is made to Figs. 1 to 4The utility model discloses a leveling device, including a plurality of above -mentioned heat -insulating leveling mechanism, still including jig 3, bottom plate 4, connecting block 5 and standard block 6, standard block 6 and heat -insulating leveling mechanism are located between jig 3 with bottom plate 4, and the spacing between the jig 3 with bottom plate 4 is adjusted for the heat -insulating leveling mechanism, the connecting block 5 is connected respectively in the side wall of heat -insulating leveling mechanism with jig 3, to fix the connection of jig 3 with heat -insulating leveling mechanism, the number of standard block 6 is at least three, the heat -insulating leveling mechanism includes heat -insulating subassembly 1 and adjusting assembly 2, and heat -insulating subassembly 1 is located at the top of adjusting assembly 2.

[0031] Specifically, leveling device mainly by jig 3, bottom plate 4, connecting block 5, standard block 6 and a plurality of heat -insulating leveling mechanism are composed, and each component cooperates with each other, and the leveling and stable support function of jig 3 are realized jointly. Jig 3 is the platform of carrying out specific process operation, and it usually needs to keep the flatness and precision of height. Bottom plate 4 is located at the bottom of whole jig 3, and provides basic support for other components. Heat -insulating leveling mechanism is arranged between jig 3 and bottom plate 4, and is used to adjust the spacing between jig 3 and bottom plate 4, to realize the leveling function of jig 3. Heat -insulating piece 12 adopts ceramic ball, has good heat -insulating property and rigidity, and is in point contact with jig 3, greatly reduces the heat transfer area. Connecting block 5 can fix jig 3 and heat -insulating leveling mechanism together by bolt connection, welding or other suitable connecting mode, prevents the relative displacement of both in the use process, to guarantee the stability and adjusting precision of jig 3 connecting block 5, to guarantee the firmness of connection.

[0032] The number of standard block 6 is at least three, and is placed between jig 3 and bottom plate 4. It can be understood that the height of standard block 6 is all consistent standard size, and is used to be auxiliary to determine the levelness of jig 3. In actual application, first, the horizontal plane of jig 3 is determined through three standard blocks 6, then the spacing between the remaining point position of jig 3 except standard block 6 and bottom plate 4 is adjusted through adjusting heat -insulating leveling mechanism, to make jig 3 reach the horizontal state determined by three standard blocks 6. In other embodiments, preferably, more quantity of standard blocks 6 can be used to determine the levelness of jig 3 more accurately.

[0033] Further, the heat -insulating leveling mechanism in the embodiment mainly consists of heat -insulating subassembly 1 and adjusting assembly 2 two big parts, and is arranged in the upper and lower. It can be understood that the heat -insulating leveling mechanism is used to adjust the spacing between jig 3 and bottom plate 4, and the upper and lower arrangement of heat -insulating subassembly 1 and adjusting assembly 2 in the embodiment is sequentially arranged from jig 3 to bottom plate 4. Heat -insulating subassembly 1 plays the heat -insulating role at the top, and adjusting assembly 2 is below and is used to realize the height adjusting function.

[0034] In an embodiment, the adjusting assembly 2 comprises a fixed block 21, a first adjusting block 22 and a second adjusting block 23, the first adjusting block 22 and the second adjusting block 23 are wedge structures, the top surface of the first adjusting block 22 and the bottom surface of the second adjusting block 23 are matching inclined surfaces, and the top surface of the first adjusting block 22 and the bottom surface of the second adjusting block 23 are closely arranged.

[0035] Specifically, the adjusting assembly 2 is a key part to realize the mechanism adjusting function, which comprises a fixed block 21, a first adjusting block 22 and a second adjusting block 23. The first adjusting block 22 and the second adjusting block 23 are wedge structures, the top surface of the first adjusting block 22 and the bottom surface of the second adjusting block 23 are matching inclined surfaces, and the two are closely arranged. It can be understood that, in the embodiment, the first adjusting block 22 and the second adjusting block 23 preferably adopt a cylindrical body. In the embodiment, the top surface of the first adjusting block 22 is an inclined surface cut at the position of the side wall of the first adjusting block 22 close to the second adjusting block 23, and the bottom surface of the second adjusting block 23 is an inclined surface cut at the position of the side wall of the second adjusting block 23 close to the first adjusting block 22, so that the first adjusting block 22 and the second adjusting block 23 are closely arranged and connected in a wedge shape. In actual application, the first adjusting block 22 and the second adjusting block 23 can be designed into other shapes, such as a square block, to adapt to different use scenarios.

[0036] When the first adjusting block 22 moves in the horizontal direction, due to the effect of the inclined surface, the second adjusting block 23 will produce a corresponding displacement in the vertical direction. This design ingeniously utilizes the mechanical principle of the wedge structure to convert the horizontal movement into vertical movement, thereby realizing the height adjustment of the second adjusting block 23. The fixed block 21 plays a role of fixation and support in the whole adjusting assembly 2, and provides a relatively stable environment for the movement of the first adjusting block 22 and the second adjusting block 23, ensuring that the two can accurately displace in the designed manner during the movement, thereby realizing the adjusting function of the whole mechanism.

[0037] In an embodiment, the fixed block 21 is provided with a horizontal adjusting groove 211 and a vertical adjusting groove 212, the second adjusting block 23 is embedded in the vertical adjusting groove 212, the first adjusting block 22 is arranged in the horizontal adjusting groove 211, and the vertical adjusting groove 212 is communicated with the horizontal adjusting groove 211.

[0038] Specifically, the horizontal adjustment groove 211 in the fixed block 21 is a special accommodating space and movement track designed for the first adjustment block 22, and the size of the groove is matched with the first adjustment block 22, which plays a positioning role in the horizontal direction and limits the freedom of the first adjustment block 22 in other directions. It can be understood that the horizontal direction in the embodiment is the length direction between the higher end and the lower end of the slope of the first adjustment block 22 and the second adjustment block 23 in the horizontal projection. The vertical adjustment groove 212 is used to accommodate the second adjustment block 23 and position and constrain the second adjustment block 23 in the vertical direction, so as to ensure that the second adjustment block 23 can only move in the vertical direction. The depth, width and other size parameters of the vertical adjustment groove 212 are determined according to the size and movement range of the second adjustment block 23, so as to ensure that the second adjustment block 23 can smoothly move up and down in the groove and prevent it from shaking or deviating from the vertical direction during movement.

[0039] In an embodiment, the adjustment assembly 2 further comprises a pushing piece 24, and the fixed block 21 is provided with a horizontal hole groove 213, and the pushing piece 24 passes through the horizontal hole groove 213 and is connected to the first adjustment block 22 to push the first adjustment block 22 to move horizontally.

[0040] Specifically, the pushing piece 24 cooperates with the horizontal hole groove 213 on the fixed block 21 to drive the first adjustment block 22 to move horizontally. The horizontal hole groove 213 is a special channel opened in the fixed block 21, and the direction is horizontal, which provides a path for the pushing piece 24 to pass through the fixed block 21 and a guiding effect. After the pushing piece 24 passes through the horizontal hole groove 213, it is connected with the first adjustment block 22, so that the movement of the pushing piece 24 can be directly transmitted to the first adjustment block 22, ensuring the synchronization of the movement of the two. When an external force is applied to the pushing piece 24, due to the connection between the pushing piece 24 and the first adjustment block 22 and the constraint of the pushing piece 24 in the horizontal hole groove 213, the external force will be converted into the power to push the first adjustment block 22 to move in the horizontal direction. The first adjustment block 22 moves horizontally in the horizontal adjustment groove 211, and the size and direction of the displacement depend on the size and direction of the external force acting on the pushing piece 24. Due to the effect of the slope, the horizontal displacement of the first adjustment block 22 causes the corresponding displacement of the second adjustment block 23 in the vertical direction, so as to realize the height adjustment of the second adjustment block 23 and further adjust the height of the heat insulation assembly 1.

[0041] In an embodiment, the pushing piece 24 is a top wire.

[0042] Specifically, the top screw is a rod with a specific thread structure, which is connected with the first adjusting block 22 after passing through the horizontal hole slot 213 on the fixed block 21. When the operator rotates the top screw, the rotational movement of the top screw is converted into linear movement in the horizontal direction due to the thread cooperation between the top screw and the horizontal hole slot 213 of the fixed block 21, thereby pushing the first adjusting block 22 to horizontally displace in the horizontal adjusting slot 211. At the same time, the thread structure of the top screw makes the adjusting process have high precision, and through rotating the top screw, the micro displacement adjustment of the first adjusting block 22 can be realized, thereby accurately controlling the height adjustment of the entire mechanism. The operator can accurately adjust the rotation angle of the top screw according to actual needs to achieve the required height adjustment effect.

[0043] In an embodiment, the heat insulation assembly 1 comprises a heat insulation pad 11 and a heat insulation piece 12, which is arranged between the heat insulation pad 11 and the second adjusting block 23.

[0044] Specifically, the upper surface of the heat insulation pad 11 is in contact with the jig 3 or other related components, and the lower surface is matched with the heat insulation piece 12. The heat insulation piece 12 is located between the heat insulation pad 11 and the second adjusting block 23, and plays a key role in heat insulation and support, forming a layered heat insulation structure. The heat insulation pad 11 first reduces the heat transferred from the jig 3, and the heat insulation piece 12 further prevents the heat from being conducted to the second adjusting block 23 and other lower components, while providing support for the jig 3 in the vertical direction. In this embodiment, the heat insulation pad 11 preferably adopts a flat plate structure to enhance the connection stability with the jig 3.

[0045] In an embodiment, the heat insulation piece 12 is a ceramic ball, the bottom of the heat insulation pad 11 is provided with a first connecting groove 111 for accommodating the ceramic ball, and the top of the second adjusting block 23 is provided with a second connecting groove 231 for accommodating the ceramic ball.

[0046] Specifically, in the present embodiment, the heat insulating member 12 preferably adopts a sphere made of ceramic material, which has good heat insulation performance and rigidity. The low thermal conductivity of the ceramic material itself makes it difficult for heat to be conducted through the ceramic sphere, thereby effectively preventing the heat from being transferred from the jig 3 to the lower part. Meanwhile, the rigidity of the ceramic sphere can ensure that it is not easily deformed when bearing pressure, thereby providing stable support for the jig 3. The spherical shape of the ceramic sphere makes it contact other parts in a point contact, greatly reducing the heat transfer area and further enhancing the heat insulation effect. The first connecting groove 111 provided at the bottom of the heat insulating pad 11 is used to accommodate the ceramic sphere, so that the ceramic sphere can be stably placed therein. The depth and width of the first connecting groove 111 are carefully designed to ensure that the ceramic sphere can be firmly embedded therein and not easily fall off, and at the same time, the ceramic sphere can have a certain space for movement when subjected to pressure, so as to adapt to different stress conditions and adjustment requirements. The second connecting groove 231 at the top of the second adjustment block 23 is also used to accommodate the ceramic sphere, and the shape and size of the second connecting groove 231 are also adapted to the ceramic sphere. The position and depth of the second connecting groove 231 on the second adjustment block 23 are accurately calculated to ensure that the ceramic sphere can correspond to the first connecting groove 111 on the heat insulating pad 11, so that the ceramic sphere can stably play a role of heat insulation and support between the heat insulating pad 11 and the second adjustment block 23.

[0047] In an embodiment, the first connecting groove 111 is a square groove, and the second connecting groove 231 is a tapered groove.

[0048] Specifically, the first connecting groove 111 is a square groove, and the cross-sectional shape thereof is a regular rectangle. The side length and depth of the square groove are designed according to the size of the ceramic sphere and the actual installation and use requirements. The side length of the square groove is slightly larger than the diameter of the ceramic sphere, so that the ceramic sphere can be smoothly placed into the groove, and there is not too much shaking in the groove. Meanwhile, when the ceramic sphere is located at the middle position of the square groove, the ceramic sphere has only one contact point with the heat insulating pad 11, greatly reducing the contact area with the heat insulating pad 11 and thereby reducing the heat transfer efficiency. The depth of the square groove ensures that a part of the ceramic sphere can be embedded therein, so as to achieve stable connection and support. The four right-angled sides of the square groove can limit the movement of the ceramic sphere in the horizontal direction, ensuring that the ceramic sphere always remains in the correct position during work, thereby effectively playing the functions of heat insulation and support. The square groove at the bottom of the heat insulating pad 11 plays a role of fixing the ceramic sphere, providing a stable support plane for the ceramic sphere, so that the ceramic sphere will not roll or deviate when bearing the pressure of the jig 3. It can be understood that the four corners in the first connecting groove 111 are respectively provided with cylindrical grooves 112, thereby reducing local stress concentration and preventing the heat insulating pad 11 from being damaged or broken due to external force impact.

[0049] The second connecting groove 231 is a tapered groove. The top of the tapered groove is large in diameter, which is larger than the diameter of the ceramic ball, so that the ceramic ball can smoothly enter the groove. The diameter of the tapered groove gradually decreases from the top to the bottom, forming a funnel-like shape. The diameter of the bottom of the tapered groove is smaller than the diameter of the ceramic ball, so as to limit the ceramic ball and stably accommodate the ceramic ball in the tapered groove. In the case of external force or vibration of the jig 3, the stability of the ceramic ball in the tapered groove can be guaranteed, so as to ensure that the ceramic ball can stably play a role of heat insulation and support in the working process.

[0050] In an embodiment, the standard block 6 and the jig 3 are provided with the heat insulation assembly 1. The jig 3, the heat insulation assembly 1 and the standard block 6 are sequentially connected from top to bottom.

[0051] Specifically, in the vertical direction, the jig 3, the heat insulation assembly 1 and the standard block 6 are sequentially arranged from top to bottom. The jig 3 is located at the top as the main platform for performing specific process operations. The heat insulation assembly 1 is clamped between the jig 3 and the standard block 6, preventing excessive heat conduction of the jig 3 to the standard block 6. The standard block 6 is located at the bottom, providing certain support and reference for the entire jig 3 system. On the one hand, when the jig 3 generates heat in the working process, the heat insulation assembly 1 can effectively block the heat conduction to the standard block 6, thereby avoiding the size change or performance change of the standard block 6 due to heating, so as to ensure the stability and accuracy of the standard block 6 as a reference. On the other hand, the heat insulation assembly 1 can also reduce the heat conduction to other components below, protecting other parts of the entire jig 3 system from the adverse effects of the heat of the jig 3, maintaining the temperature stability of the entire system, and ensuring the accuracy and performance of each component are not disturbed by temperature changes. It can be understood that the top of the standard block 6 is provided with a second connecting groove 231 for accommodating the ceramic ball.

[0052] In an embodiment, the bottom of the jig 3 is provided with a flat groove 31, and the heat insulation assembly 1 is arranged in the flat groove 31.

[0053] Specifically, the flat groove 31 arranged at the bottom of the jig 3 is a groove for accommodating the heat insulation assembly 1, and the size thereof is determined according to the size of the heat insulation assembly 1 and the overall structure and functional requirements of the jig 3. In this embodiment, the heat insulation assembly 1 includes a heat insulation pad 11 and a ceramic ball. The flat groove 31 is used to accommodate the heat insulation pad 11, and the depth thereof is just enough to accommodate the heat insulation pad 11, so that the heat insulation pad 11 can be stably placed therein and will not easily fall out or shake. The ceramic ball is located between the heat insulation pad 11 and the second adjusting block 23, and is fixed by the first connecting groove 111 at the bottom of the heat insulation pad 11 and the second connecting groove 231 at the top of the second adjusting block 23.

[0054] In summary, the leveling device of the embodiment, through the heat insulation leveling mechanism, realizes accurate leveling of the jig 3, wherein the top wire cooperates with the wedge body structure to accurately adjust the height of the ceramic ball to change the distance between the jig 3 and the bottom plate 4; the design of the ceramic ball and the heat insulation pad 11 in the heat insulation assembly 1 can effectively reduce the heat conduction of the jig 3 to the bottom part, maintain the temperature stability, guarantee the part accuracy and stability; the connecting block 5 firmly connects the jig 3 and the heat insulation leveling mechanism to prevent relative displacement; the at least three standard blocks 6 are used to accurately determine the levelness of the jig 3, and the heat insulation assembly 1 between the standard block 6 and the jig 3 can avoid the influence of the jig 3 on the standard block 6, thereby improving the leveling accuracy, protecting the parts from heat damage, prolonging the service life, making the jig 3 adapt to different process requirements and working environments, and guaranteeing the process operation accuracy and quality.
