Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal panel detection and repair, and in particular to a liquid crystal panel conveying device with adjustable spacing. Background Art

[0002] With the widespread application of LCD panels, their production capacity is also rising rapidly. In the LCD panel industry, automated production has become the mainstream, and automated equipment plays a vital role in the production process. In an automated production line, there are a large number of product transfer mechanisms for each process, both within the equipment and between equipment. Among them, the continuous conveyor (CV) is one of the commonly used transfer mechanisms in many automated equipment.

[0003] At present, the CV conveying structure commonly used in existing equipment usually adopts a single or multiple fixed flat belts. The width dimension of CV is usually determined according to the maximum product size to be conveyed, and an additional guide structure will be added to ensure the stability of the product during the conveying process. However, for products conveyed on a flat surface, the contact surface between the product and the belt surface must remain flat to ensure that the characteristics of the product remain fixed during the conveying process and to ensure the stability of the intermediate detection. During the module assembly stage of LCD panel production, there are usually protruding mounting columns on the back of the product, and the size and position of these mounting columns are different for products of different specifications. If the traditional CV conveying method is used, when the product is placed on the CV surface, it is easy to tilt, tip over or jam, which will cause the subsequent process to fail to smoothly receive or remove materials. Summary of the invention

[0004] In order to solve all or part of the problems of the above-mentioned prior art, the present invention provides a liquid crystal panel conveying device with adjustable spacing. Through the setting of the spacing adjustment unit, especially the cooperation of the guide rail support mechanism and the movable locking mechanism, the spacing between the conveying units can be flexibly adjusted according to liquid crystal panels of different specifications, effectively solving the problems of tilting, tipping or jamming that may occur in traditional conveying devices when processing products of different sizes.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A liquid crystal panel conveying device with adjustable spacing, comprising:

[0007] At least two sets of parallelly arranged conveying units for carrying and conveying products;

[0008] A power driving unit, synchronously connected to each of the transmission units, and used to drive the transmission units to operate synchronously;

[0009] At least one set of spacing adjustment units, which are arranged between each of the said conveying units, and include a guide rail type support mechanism and a movable locking mechanism. The guide rail type support mechanism extends in a direction perpendicular to the conveying direction, and the bottom of each of the said conveying units is slidably connected to the guide rail type support mechanism; the movable locking mechanism includes a limiting part arranged parallel to the guide rail type support mechanism, and a locking component arranged at the bottom of each of the said conveying units and cooperating with the limiting part;

[0010] The bottom of each of the said conveying units is slidably arranged on the guide rail type support mechanism, and the locking component is engaged and separated from the limiting part to realize the locking adjustment of the transmission spacing between adjacent said conveying units.

[0011] The locking component includes a locking tooth block and an adjustment component connected thereto. The bottom surface of the locking tooth block is provided with a first tooth-shaped structure, and the top surface of the limiting part is provided with a second tooth-shaped structure meshing with the first tooth-shaped structure. The adjustment mechanism can move the locking tooth block in the vertical direction to make the first tooth-shaped part and the second tooth-shaped part engage and lock or disengage and release.

[0012] The tooth pitch of the first tooth-shaped structure and the second tooth-shaped structure is 1-5 mm, and the movement accuracy is ±1 mm.

[0013] The adjustment component includes a fixed block and an adjustment rod. The fixed block is fixed at the bottom of the conveying unit, and an adjustment cavity vertically penetrating is arranged inside it; the lower end of the adjustment rod is fixedly connected to the locking tooth block, the upper end passes through the adjustment cavity and extends to the outside, and an operation handle is installed at the upper end; an elastic member is sleeved on the adjustment rod, the lower end of the elastic member abuts against the upper surface of the locking tooth block, and the upper end is fixed to the top surface of the adjustment cavity of the fixed block.

[0014] The length of the bottom of the operation handle is greater than the transverse inner diameter of the adjustment cavity. Lift the operation handle upward so that its bottom completely disengages from the adjustment cavity, and rotate the operation handle by 90°, so that it is clamped at the upper opening position of the adjustment cavity, making the locking tooth block disengage from the meshing state.

[0015] The locking component further includes an indicating member arranged on one side of the adjustment component, and a scale component corresponding to the indicating member is arranged in parallel on the side of the limiting part.

[0016] Each group of the said conveying units includes a driving wheel assembly, a driven wheel assembly and a transmission belt assembly sleeved between the two; it further includes a base. The power driving unit includes a power source fixed on the base and a driving shaft coaxially connected thereto. The driving shaft penetrates through the driving wheel assembly and realizes synchronous driving through keyway cooperation.

[0017] It includes two sets of the spacing adjustment units, which are respectively arranged in the bottom areas of the driving wheel assembly and the driven wheel assembly; the locking components of one set of the spacing adjustment units are arranged at the bottom of the driving wheel assembly, and the locking components of the other set of the spacing adjustment units are arranged at the bottom of the driven wheel assembly.

[0018] The conveying unit further includes a tensioning assembly, which includes a mounting seat, two guide rollers and a tensioning roller. The mounting seat is mounted on the belt assembly. The two guide rollers are symmetrically arranged at both ends of the mounting seat. The tensioning roller is located below the middle of the two guide rollers. The guide rollers are in rolling contact with the lower surface of the belt assembly, and the tensioning roller is in rolling contact with the upper surface of the belt assembly through a lifting structure.

[0019] The conveying unit further includes a guide roller, which is installed on the downstream side of the conveying direction of the driven wheel assembly through an adjustable support frame and is arranged at the same height as the belt assembly, so as to form a continuous and flat bearing plane at the connection between the upstream and downstream conveying units.

[0020] The present invention has at least the following beneficial effects:

[0021] 1) By providing at least two sets of parallel conveying units and adjustable spacing units, the spacing between the conveying units can be flexibly adjusted according to different specifications of the liquid crystal panel. In particular, the cooperation between the rail-type support mechanism and the movable locking mechanism in the spacing adjustment unit makes the adjustment of the spacing between the conveying units more accurate and convenient. The design of the locking component further ensures the stability after the spacing adjustment and avoids the problem of unstable conveying caused by the change of the spacing.

[0022] 2) Through the meshing and locking or disengaging and releasing of the locking tooth block and the limiting part, combined with the operating handle of the adjusting component, the operator can easily achieve the rapid adjustment and locking of the spacing. The special design of the operating handle enables it to disengage from the meshing state through simple lifting and rotating actions, further simplifying the operation process. In addition, the cooperation between the indicating part and the scale component makes the spacing adjustment more intuitive and accurate, and the operator can clearly read the current position of the locking tooth block.

[0023] 3) The introduction of the tensioning assembly and the guide roller in the conveying unit further optimizes the performance of the conveying device. The tensioning assembly ensures the stable operation of the belt through the cooperation of the guide rollers and the tensioning roller, and avoids the problems of slipping or deviation caused by the slack of the belt. The setting of the guide roller ensures the seamless connection between the upstream and downstream conveying units, forms a continuous and flat bearing plane, and further improves the conveying efficiency and product quality.

Specific embodiments

[0033] The following will clearly and completely describe the technical solutions in the specific embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] In an embodiment of the present invention, with reference to Figures 1 to 7 as shown, a liquid crystal panel conveying device with adjustable spacing is provided. The device includes at least two groups of parallel conveying units 1 for carrying and transporting liquid crystal panel products 6. Each conveying unit 1 is synchronously connected through a power driving unit 2, and the power driving unit 2 can drive all the conveying units 1 to operate synchronously at the same rate, so as to ensure the smoothness of the product 6 during the conveying process. In addition, the device also includes at least one group of spacing adjusting units arranged between each conveying unit 1. The spacing adjusting unit is composed of a guide rail type supporting mechanism 3 and a movable locking mechanism 4. The guide rail type supporting mechanism 3 extends along a direction perpendicular to the conveying direction, and the bottom of each conveying unit 1 is slidably connected to the guide rail type supporting mechanism 3, so as to allow the conveying unit 1 to move along a direction perpendicular to the conveying direction on the guide rail to adapt to liquid crystal panel products 6 of different sizes.

[0035] The movable locking mechanism 4 includes a limiting part 41 arranged parallel to the guide rail type supporting mechanism 3, and a locking component 42 arranged at the bottom of each conveying unit 1 and cooperating with the limiting part 41. By the engagement of the locking component 42 and the limiting part 41, the locking adjustment of the transmission spacing between adjacent conveying units 1 can be realized. When the spacing needs to be adjusted, the conveying unit 1 can slide on the guide rail type supporting mechanism 3 to the required position, and then through the cooperation of the locking component 42 and the limiting part 41, the conveying unit 1 is fixed at this position, so as to realize the precise locking adjustment of the transmission spacing between adjacent conveying units 1. This adjustable spacing design can effectively adapt to liquid crystal panel products 6 of different specifications. Especially for the case where there are protruding mounting columns on the back of the product 6, it can effectively avoid the phenomena of tilting, toppling or jamming of the product 6 during the conveying process, and thus ensure the smooth progress of subsequent processes.

[0036] The locking assembly 42 includes a locking tooth block 421 and an adjusting assembly 422 connected thereto. The bottom surface of the locking tooth block 421 is provided with a first tooth-shaped structure, and the top surface of the limiting portion 41 is provided with a second tooth-shaped structure meshing with the first tooth-shaped structure. The adjusting assembly 422 can drive the locking tooth block 421 to move in the vertical direction, so as to realize the meshing lock or disengagement release between the first tooth-shaped structure and the second tooth-shaped structure. When the locking tooth block 421 moves downward, the first tooth-shaped structure meshes with the second tooth-shaped structure, realizing the fixation and pitch locking of the conveying unit 1; when the locking tooth block 421 moves upward, the first tooth-shaped structure disengages from the second tooth-shaped structure, and the conveying unit 1 can slide freely on the rail-type support mechanism 3 to adjust the pitch. In order to ensure the reliability and adjustment accuracy of the locking assembly 42, the tooth pitch of the first tooth-shaped structure and the second tooth-shaped structure is designed to be 1-5 mm, and the movement accuracy reaches ±1 mm. This design not only ensures the stability of the locking assembly 42 during meshing, but also can effectively prevent retraction in the locked state, realizing high-precision pitch adjustment, so as to meet the precise pitch requirements of different specifications of liquid crystal panel products 6 during the conveying process.

[0037] The adjusting assembly 422 includes a fixing block 4221 and an adjusting rod. The fixing block 4221 is fixed to the bottom of the conveying unit 1, and an adjusting cavity penetrating vertically is provided inside it. The lower end of the adjusting rod is fixedly connected to the locking tooth block 421, the upper end passes through the adjusting cavity and extends to the outside, and an operating handle 4222 is installed at the upper end. An elastic member is also sleeved on the adjusting rod, the lower end of the elastic member abuts against the upper surface of the locking tooth block 421, and the upper end is fixedly connected to the top surface of the adjusting cavity of the fixing block 4221. This structural design enables the locking tooth block 421 to remain in the meshing state under the action of the elastic member, and at the same time realizes the movement and disengagement of the locking tooth block 421 through the operating handle 4222. The length of the bottom of the operating handle 4222 is greater than the transverse inner diameter of the adjusting cavity, and this design enables the operating handle 4222 to realize the disengagement of the locking tooth block 421 through a simple action. The specific operation is as follows: lift the operating handle 4222 upward so that its bottom completely disengages from the adjusting cavity, and rotate the operating handle 4222 by 90°, so that it is stuck at the upper opening position of the adjusting cavity. At this time, the locking tooth block 421 moves upward under the action of the elastic member, so as to disengage from the meshing state with the limiting portion 41, and the conveying unit 1 can slide freely on the rail-type support mechanism 3 to adjust the pitch. In addition, the locking assembly 42 further includes an indicating member 43 arranged on one side of the adjusting assembly 422, and a scale assembly arranged on the side of the limiting portion 41. The scale assembly corresponds to the indicating member 43 and is used to visually display the current position of the locking tooth block 421 and the accuracy of pitch adjustment. Through the cooperation of the indicating member 43 and the scale assembly, the operator can clearly read the meshing position of the locking tooth block 421.

[0038] In an embodiment of the present invention, each conveying unit 1 includes a driving wheel assembly 11, a driven wheel assembly 12, and a transmission belt assembly 13 sleeved between the two. The transmission belt assembly 13 is used to carry and transport the liquid crystal panel product 6, while the driving wheel assembly 11 and the driven wheel assembly 12 achieve synchronous operation through the tensioning effect of the transmission belt assembly 13, ensuring the smoothness of the product 6 during the conveying process. In addition, the device further includes a base 5, and the power driving unit 2 is fixed on the base 5. The power driving unit 2 includes a power source 21 and a driving shaft 22 coaxially connected thereto. The driving shaft 22 penetrates through the driving wheel assembly 11 and achieves synchronous driving through keyway fit. This design ensures the efficient transmission of power and at the same time guarantees the stable operation of the conveying unit 1. In order to flexibly adjust the spacing between the conveying units 1, the present invention provides two sets of spacing adjusting units, which are respectively located in the bottom regions of the driving wheel assembly 11 and the driven wheel assembly 12. The locking component 42 of one set of spacing adjusting units is arranged at the bottom of the driving wheel assembly 11, and the locking component 42 of the other set of spacing adjusting units is arranged at the bottom of the driven wheel assembly 12. This layout makes the spacing adjustment of the conveying unit 1 more flexible, enabling independent spacing adjustment between the driving wheel assembly 11 and the driven wheel assembly 12, so as to better adapt to liquid crystal panel products 6 of different specifications.

[0039] The conveying unit 1 further includes a tensioning component 14 to further improve the performance and reliability of the conveying device. The tensioning component 14 includes a mounting seat 141, two guiding rollers 142, and a tensioning roller 143. The mounting seat 141 is fixedly installed on the transmission belt assembly 13, playing a role of support and positioning. The two guiding rollers 142 are symmetrically arranged at both ends of the mounting seat 141, and their main function is to guide the running direction of the transmission belt, ensuring that the transmission belt remains stable during operation. The tensioning roller 143 is located below the two guiding rollers 142 and is in rolling contact with the upper surface of the transmission belt assembly 13 through a lifting structure. This design can adjust the position of the tensioning roller 143 as needed, thereby achieving the tensioning or relaxation of the transmission belt, ensuring that the transmission belt always maintains an appropriate tension during operation, and avoiding slipping or deviation caused by the slack of the transmission belt. Specifically, the guiding rollers 142 are in rolling contact with the lower surface of the transmission belt assembly 13, playing a role of support and guidance, ensuring that the transmission belt does not deviate from the predetermined track during operation. The tensioning roller 143 is in rolling contact with the upper surface of the transmission belt assembly 13 through a lifting structure. By adjusting the height of the tensioning roller 143, the tension degree of the transmission belt can be changed, thereby ensuring that the transmission belt always maintains stability and efficiency during operation.

[0040] The conveying unit 1 further includes a guiding roller 15 to further optimize the connection effect between the conveying units 1. The guiding roller 15 is installed on the downstream side of the conveying direction of the driven wheel assembly 12 through an adjustable support frame and is arranged at the same height as the conveyor belt assembly 13. This design can ensure that a continuous and flat bearing plane is formed at the connection between the upstream and downstream conveying units 1, thus avoiding product 6 jamming or damage caused by unevenness at the connection. The main function of the guiding roller 15 is to guide the running direction of the conveyor belt and ensure a smoother transition of the conveyor belt at the connection. By setting the adjustable support frame, the position of the guiding roller 15 can be adjusted according to actual needs to keep it at the same height as the conveyor belt assembly 13, thereby achieving seamless connection between the upstream and downstream conveying units 1. This design not only improves the overall performance of the conveying device but also significantly enhances the conveying quality and efficiency of product 6.

[0041] Through the above design, the adjustable-spacing liquid crystal panel conveying device of the present invention can not only achieve high-precision spacing adjustment but also ensure the stability and reliability of the conveying process, effectively solving the problems of inclination, toppling or jamming that may occur in traditional conveying devices when dealing with products 6 of different specifications, and significantly improving the automation level and production efficiency of liquid crystal panel production.

[0042] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
