Description

Technical Field

[0001] This utility model relates to the field of ceramic plate exposure technology, specifically to an automatic positioning mechanism for ceramic plate exposure. Background Technology

[0002] Ceramic plate exposure is a process that uses photochemical reactions to form potential or visible images on a ceramic substrate, typically involving steps such as photoresist replication, exposure, development, and etching.

[0003] Currently, when exposing ceramic plates, a manual exposure machine is often used in conjunction with a ceramic plate fixing fixture. Before exposure, the ceramic plate needs to be aligned with the film to be exposed, but this step requires manual intervention with a manual exposure machine, which is not fast enough.

[0004] Currently, the alignment of the ceramic plate and the exposure film is done manually, which is inefficient and has limited accuracy, thus affecting the subsequent exposure process. Utility Model Content

[0005] The purpose of this invention is to provide an automatic positioning mechanism for ceramic plate exposure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic positioning mechanism for ceramic plate exposure, comprising a base and a vision acquisition group, wherein two sets of alignment motor groups are installed at one top end of the base, and the power output end of the alignment motor groups is connected to an alignment linkage group, and a lower platform frame group is connected to the top of the alignment linkage group, and a workpiece is placed in the middle of the top surface of the lower platform frame group, while a vacuum nozzle group is installed at the bottom of the lower platform frame group, and the vision acquisition group is mounted directly above the workpiece.

[0007] Furthermore, backlight groups are symmetrically installed at the bottom center of the lower platform frame, and a support base is installed at the bottom of the lower platform frame away from the alignment linkage group.

[0008] Furthermore, the alignment motor assembly is installed at one end of the bottom of the lower frame assembly, and the two alignment motor assemblies are respectively arranged in the horizontal X-axis and Y-axis directions.

[0009] Furthermore, the bottom of the lower platform frame assembly is fixedly connected to the top of the alignment linkage assembly, and the middle part of the lower platform frame assembly is made of transparent material.

[0010] Furthermore, the vacuum nozzle assembly is located at the bottom center of the lower platform frame assembly and is arranged in four equidistant arrays, with the output end of the vacuum nozzle assembly vertically penetrating through the middle of the lower platform frame assembly.

[0011] Furthermore, the end of the vacuum nozzle assembly away from the output end is provided with a quick connector structure, the backlight assembly adopts an array structure, and the backlight assembly is located on both sides below the vacuum nozzle assembly.

[0012] Furthermore, the output end of the alignment motor group is connected to the alignment linkage group through a lead screw, slider and guide rail structure, and the support base is provided with two sets at the bottom of the lower platform frame group.

[0013] Furthermore, the visual image acquisition group is vertically mounted directly above the center of the lower frame group, and four groups of visual image acquisition groups are arranged in an equidistant array.

[0014] This utility model provides an automatic positioning mechanism for ceramic plate exposure, which has the following advantages: 1. This utility model employs a CCD vision system within the visual image acquisition group. CCD vision, or charge-coupled device vision inspection system, is a technology that converts optical images into digital signals for automated inspection. The visual image acquisition group simultaneously uses a high-resolution industrial camera to acquire images. Through preprocessing (such as noise reduction and enhancement) and feature extraction algorithms, positioning data is generated and transmitted to the PLC for automated control. The CCD image sensor captures product images in industrial production, which are then digitally processed to achieve automatic positioning, measurement, identification, and quality inspection. Utilizing the above structure, in conjunction with the operation of the alignment motor group, the alignment linkage group connected to the lower frame group is synchronously displaced. This design allows for mechanical execution, enabling the workpiece, which was originally not in a precise position, to be automatically aligned relative to the exposure film. Compared to manual alignment, this improves alignment accuracy and efficiency.

[0015] 2. This utility model features a vacuum nozzle assembly and a backlight assembly installed at the bottom of the lower frame assembly. The middle of the lower frame assembly is made of a transparent structure, allowing the backlight assembly to provide sufficient exposure lighting to the bottom of the workpiece. Simultaneously, the vacuum nozzle assembly can be connected to an external air pump to achieve vacuum suction. This structural design provides sufficient structural stability and limit without damaging the surface structure of the workpiece, preventing unnecessary structural displacement during exposure and reducing processing errors. Furthermore, the support base provides structural support for the lower frame assembly, ensuring sufficient stability under the drive of the alignment motor assembly and alignment linkage assembly.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 3 As shown, an automatic positioning mechanism for ceramic plate exposure includes a base 1 and a vision acquisition group 7. Two alignment motor groups 2 are mounted on the top end of the base 1, and the power output end of the alignment motor groups 2 is connected to an alignment linkage group 3. A lower platform frame group 4 is connected to the top of the alignment linkage group 3, and a workpiece 5 is placed in the middle of the top surface of the lower platform frame group 4. A vacuum nozzle group 6 is mounted on the bottom of the lower platform frame group 4. The vision acquisition group 7 is positioned directly above the workpiece 5. The output end of the alignment motor groups 2 is connected via a lead screw and a slider... The guide rail structure is connected to the alignment linkage group 3, and the support base 9 is provided with two sets at the bottom of the lower stage frame group 4. The visual image acquisition group 7 is vertically mounted on the middle of the lower stage frame group 4, and four sets of visual image acquisition groups 7 are arranged in an equidistant array. The visual image acquisition group 7 adopts a CCD vision system inside, which, together with the operation of the alignment motor group 2, drives the alignment linkage group 3 connected to the lower stage frame group 4 to move synchronously. With this design, the workpiece 5, which was originally not in a precise position, can be automatically aligned relative to the exposure film through mechanical execution.

[0020] like Figures 1 to 3As shown, backlight groups 8 are symmetrically installed on the bottom center of the lower frame group 4, and a support base 9 is installed at the bottom end of the lower frame group 4 away from the alignment linkage group 3. The alignment motor group 2 is installed at one bottom end of the lower frame group 4, and the two alignment motor groups 2 are respectively arranged in the horizontal X-axis and Y-axis directions. The bottom of the lower frame group 4 is fixedly connected to the top of the alignment linkage group 3, and the middle part of the lower frame group 4 is made of transparent material. The vacuum nozzle group 6 is set in the bottom center of the lower frame group 4 and is arrayed at equal intervals. Four sets of vacuum nozzles are provided, with the output end of the vacuum nozzle set 6 vertically penetrating through the middle of the lower frame set 4. The end of the vacuum nozzle set 6 away from the output end is provided with a quick connector structure. The backlight set 8 adopts an array structure and is set on both sides below the vacuum nozzle set 6. The middle part of the lower frame set 4 adopts a transparent structure, so that the backlight set 8 can provide sufficient exposure and supplementary light to the bottom of the workpiece 5. At the same time, the vacuum nozzle set 6 can be connected to an external air pump device to realize vacuum adsorption operation.

[0021] In summary, as Figures 1 to 3 As shown, the automatic positioning mechanism for ceramic plate exposure first places the workpiece 5 to be processed in the middle of the top of the lower frame group 4. At this time, the vacuum nozzle group 6, which is pre-connected to the external air pump equipment, can vacuum adsorb the workpiece 5 under the operation of the air pump and ensure the structural stability of the workpiece 5. Then, under the operation of the vision imaging group 7, using the CCD vision system, the four vision imaging groups 7 begin to detect the special target on the workpiece 5. The computer records the initial position of the workpiece 5 and compares it with the position of the exposed film to calculate the position that the workpiece 5 needs to be corrected. Under the structural operation of the alignment motor group 2 and the alignment linkage group 3, the structural position of the lower stage frame group 4 is automatically adjusted to ensure that the workpiece 5 is in the appropriate structural position. After that, the backlight group 8 at the bottom of the lower stage frame group 4 starts to work, so that the special target on the workpiece 5 is clearly captured in the vision imaging group 7, improving the computer's contrast execution action. The alignment motor group 2 and the alignment linkage group 3 further perform correction on the lower stage frame group 4, so that the workpiece 5 fixed on the lower stage frame group 4 moves together to the corresponding exposure film position. After the alignment action is completed, the next exposure process can be carried out.
