Description

Technical Field

[0001] This utility model relates to the field of ceramic chopping tool inspection technology, and in particular to a visual inspection device for ceramic chopping tool holes. Background Technology

[0002] Ceramic cleavers, also known as ceramic tips or capillary tubes, are used as welding needles in bonding machines. They are suitable for welding LEDs, IC chips, diodes, transistors, thyristors, surface acoustic waves, and other circuits. Using ceramic as a cleaver results in high hardness, high specific gravity, and fine grains, leading to high surface finish and high dimensional accuracy of the products.

[0003] Ceramic wedges have vertical holes inside to guide bonding wires (such as gold or copper wires) for bonding. During production, these holes need to be inspected to prevent discrepancies between the hole diameter and the standard diameter. For example, Chinese Patent Publication No. CN119141338A discloses an automatic concentric grinding technology for ceramic wedges based on machine vision, relating to the field of ceramic wedge processing and inspection technology. This technology includes a vision imaging device, a rotary clamping device, a grinding wheel device, a PLC device, a concentricity correction module, and a tip grinding module. The vision imaging device provides visual images for the concentricity correction module and the tip grinding module. The rotary clamping device clamps the ceramic wedge and provides rotation. The grinding wheel device grinds the ceramic wedge. This invention, based on machine vision algorithms, achieves high-precision positioning and rapid correction of the ceramic wedge's hole center and precise grinding of the tip diameter. This solves the problems of low efficiency, missed detections, and false detections associated with manual inspection in traditional production methods, improving production efficiency, product quality, and ultimately enhancing the performance and service life of the ceramic wedge.

[0004] In practice, considering that the diameter of the shaft hole of ceramic chopping tools of different diameters is also different, the height between the detection lens and the ceramic chopping tool cannot be finely adjusted, making it difficult to ensure that the shaft hole of the ceramic chopping tool, the light source, and the lens end of the detection lens are at the same height, which may lead to detection errors. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the height between the detection lens and the ceramic chopping tool cannot be finely adjusted, and to propose a visual inspection device for the ceramic chopping tool hole.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a visual inspection device for ceramic cleaver holes, including an inspection table, a fixed frame fixedly connected to the top of the inspection table, a conveying unit and an inspection unit provided on the fixed frame, the inspection unit including an inspection lens placed on the support, and a height adjustment component provided between the inspection lens and the support;

[0008] The lens end of the detection lens is located on one side of the conveying unit, and a light shield is detachably connected to the lens end of the detection lens via an elastic structure.

[0009] Furthermore, the height adjustment assembly includes a pair of wedges, the wedge surfaces of the pair of wedges are arranged opposite each other and are slidably connected between them by a limiting part, wherein the top wedge is fixedly connected to the detection lens by a connector and slidably connected to the bracket.

[0010] Furthermore, the wedge-shaped block located at the bottom is slidably connected to the guide groove of the bracket via a guide member at the bottom. An adjusting screw is also threadedly connected inside the wedge-shaped block. The bracket is also provided with a baffle at its end, and the adjusting screw is rotatably connected to the baffle.

[0011] Furthermore, the elastic structure includes at least one pair of relief grooves, the light shield has a cylindrical structure, and an extension portion extends from the opening toward the axis to form an extension portion, the extension portion having the relief grooves symmetrically distributed thereon, and the extension portion also having a sliding groove connected to the relief groove on its inner side.

[0012] Furthermore, the ends of the two sides of the slide groove extend relative to each other, and each end is provided with a pair of deformation grooves that communicate with the extension. The inner side of the extension is provided with a stop block between the pair of deformation grooves.

[0013] Furthermore, it also includes a protruding structure corresponding to the relief groove, the protruding structure passing through the relief groove and sliding along the slide groove against the abutment, the protruding structure stopping between the abutment and the inner wall of the slide groove.

[0014] The present invention provides a visual inspection device for ceramic chopping tool holes, which has the following advantages: The present invention drives one of the wedge blocks to move laterally by rotating a screw. The wedge block slides against another wedge block through its wedge surface, thereby achieving the function of fine adjustment of the height of the inspection lens. This avoids the situation where the height of the inspection lens is fixed and cannot be adapted to the shaft hole of the ceramic chopping tool within a certain range. In addition, a light shield is provided at the lens end of the inspection lens. The light shield can effectively block stray light entering from the side of the lens, further improving the accuracy of the inspection. Moreover, the light shield can be easily installed and removed through an elastic structure. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A visual inspection device for ceramic cleaver holes includes an inspection platform 1, a fixed frame 2 fixedly connected to the top of the inspection platform 1, a conveying unit 3 and an inspection unit 4 provided on the fixed frame 2, the inspection unit 4 including an inspection lens 42 placed on a bracket 41, and a height adjustment component 5 provided between the inspection lens 42 and the bracket 41.

[0022] The lens end of the detection lens 42 is located on one side of the conveying unit 3, and the lens end of the detection lens 42 is detachably connected to a light shield 7 via an elastic structure 6.

[0023] It should be added that the bracket 41 is fixedly connected to the fixed frame 2, and the bracket 41 is set below the conveying unit 3. The conveying unit 3 includes a pair of rollers, which are rotatably connected to the fixed frame 2. One of the rollers is connected to the shaft end of the drive motor. A conveyor belt is sleeved around the pair of rollers. The ceramic chopping knife is conveyed by the conveyor belt. During the conveying process, the diameter of the shaft hole of the ceramic chopping knife is detected by the detection lens 42.

[0024] Specifically, the detection lens 42 is electrically connected to the detection terminal.

[0025] Furthermore, the height adjustment component 5 includes a pair of wedge blocks 51, the wedge surfaces of the pair of wedge blocks 51 are arranged opposite each other, and they are slidably connected by a limiting part 52. The top wedge block 51 is fixedly connected to the detection lens 42 by a connector 55, and slidably connected to the bracket 41.

[0026] Furthermore, the wedge-shaped block 51 located at the bottom is slidably connected to the guide groove 411 of the bracket 41 via the bottom guide member 53. An adjusting screw 54 is also threadedly connected inside the wedge-shaped block 51. The bracket 41 is also provided with a baffle 412 at its end, and the adjusting screw 54 is rotatably connected to the baffle 412.

[0027] In this embodiment, the limiting part 52 includes a T-shaped groove and a T-shaped block. The upper and lower wedge blocks 51 are respectively provided with the T-shaped groove and the T-shaped block on opposite sides. The T-shaped groove and the T-shaped block are slidably connected to each other, thereby driving the limiting function.

[0028] Rotating the adjusting screw 54 drives the wedge block 51 at the bottom to move laterally. During the lateral movement, the wedge surface of the wedge block 51 slides against the wedge block 51 at the top. After being resisted, the wedge block 51 at the top moves up and down under the limiting action of the connecting piece 55, thereby adjusting the height of the detection lens 42.

[0029] Specifically, the connector 55 is a screw with a T-shaped cross-section. A spring is sleeved around the screw, and the two ends of the spring abut against the bracket 41 and the baffle at the bottom of the screw, respectively. The spring is used to reset the wedge block 51 at the top.

[0030] More specifically, the elastic structure 6 includes at least one pair of relief grooves 61, the light shield 7 has a cylindrical structure, and an extension portion 71 extends from the opening toward the axis to form an extension portion 71. The extension portion 71 is symmetrically distributed with the relief grooves 61, and the extension portion 71 is also provided with a sliding groove 62 connected to the relief grooves 61 on its inner side.

[0031] In general, the ends of the sliding grooves 62 on both sides extend relative to each other, and each end is provided with a pair of deformation grooves 63 that communicate with the extension portion 71. The inner side of the extension portion 71 is provided with a stop block 64 between the pair of deformation grooves 63.

[0032] Finally, it also includes a protruding structure 65 corresponding to the relief groove 61. The protruding structure 65 passes through the relief groove 61 and slides along the sliding groove 62 against the abutment 64. The protruding structure 65 stops between the abutment 64 and the inner wall of the sliding groove 62.

[0033] In this embodiment, the light shield 7 is preferably made of a material with deformation capability such as rubber or plastic. The protruding structure 65 stops between the abutment 64 and the inner wall of the slide groove 62, thereby fixing the detection lens 42 and the light shield 7. Similarly, when unlocking the light shield 7, simply rotate the light shield 7 in the opposite direction. The protruding structure 65 abuts against and slides against the abutment 64. After disengaging from the abutment 64, it slides out along the relief groove 61 for disassembly.

[0034] Among them, guide ramps are provided on both sides of the abutment block 64.

[0035] Working method: During operation, the ceramic chopping knife is conveyed through the conveying unit 3, and the height of the detection lens 42 is finely adjusted according to the height of the shaft hole of the ceramic chopping knife.

[0036] The wedge block 51 at the bottom is driven to move laterally by adjusting the screw 54. During the lateral movement, the wedge surface of the wedge block 51 slides against the wedge block 51 at the top. After being resisted, the wedge block 51 at the top moves up and down under the limiting action of the connector 55 and the spring, so as to adjust the height of the detection lens 42.

[0037] Then, a light shield 7 can be installed on the detection lens 42 to prevent the detection lens 42 from being interfered with by external stray light. The protruding structure 65 passes through the relief groove 61 and slides along the sliding groove 62 against the abutment 64. The protruding structure 65 is stopped and fixed between the abutment 64 and the inner wall of the sliding groove 62.

[0038] Simply rotate the sunshade 7 in the opposite direction. The protruding structure 65 will contact and slide against the stop block 64. After disengaging from the stop block 64, it can be disassembled along the relief groove 61.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
