Description

Technical Field

[0001] The utility model belongs to the field of laser calibration technology, and specifically relates to a device for calibrating parts after laser cutting and original drawings. Background Art

[0002] The main purpose of parts verification is to ensure that parts meet design requirements and manufacturing standards through a series of inspections and tests, which helps to avoid failures during use and improve the overall quality and reliability of the product.

[0003] Part verification usually requires appearance inspection, dimensional inspection, material inspection, functional testing, etc. Among them, the surface quality of the parts, such as smoothness, scratches, cracks, rust, and part size measurement, all need to be carefully inspected. This can be done through direct visual inspection or combined inspection using tools such as microscopes, magnifying glasses, and industrial cameras. However, existing methods of inspection using industrial cameras all have unclear edges, resulting in inaccurate part inspection, which in turn affects the subsequent use of a batch of parts. Utility Model Content

[0004] The purpose of this utility model is to provide a device for verifying parts after laser cutting and the original image, which can make the outline of the photographed parts clearer and help industrial cameras to more accurately capture the details and features of the parts when conducting product inspection.

[0005] The technical solutions adopted in this application are as follows:

[0006] A device for verifying parts after laser cutting and their original images, comprising a conveyor belt assembly, and a positioning mechanism and a verification mechanism sequentially arranged on the conveyor belt assembly. Parts are transported by the conveyor belt assembly and sequentially pass through the positioning mechanism and the verification mechanism. A light box assembly is provided inside the conveyor belt assembly corresponding to the verification mechanism.

[0007] The verification mechanism includes fixed brackets arranged on both sides of the top of the conveyor belt assembly, the fixed brackets are equipped with light blocking plates, the top of the fixed brackets is provided with a transverse bracket, the transverse brackets connect the fixed brackets on both sides, and an industrial camera is fixed at the bottom of the transverse brackets.

[0008] In a preferred embodiment, the transmission belt assembly includes two opposing rollers, and the rollers at both ends are covered with transmission belts, wherein the transmission belt is a light-transmitting leather layer.

[0009] In a preferred solution, a bracket is fixedly mounted on the side of the fixed bracket, a lighting ring is provided at the bottom of the bracket, and a through hole is provided on the bracket corresponding to the aperture of the lighting ring.

[0010] In a preferred solution, the shooting position of the industrial camera corresponds to the through hole setting.

[0011] In a preferred embodiment, the light box assembly includes a support plate, which is horizontally mounted at the middle hole of the transmission belt. A lighting box is installed on the top of the support plate, and a lampshade is provided on the top of the lighting box.

[0012] In a preferred embodiment, the top of the lampshade is arranged to be retracted toward the middle.

[0013] In a preferred embodiment, the illumination intensity of the light box assembly is less than the illumination intensity of the lighting ring.

[0014] The technical effects achieved by this utility model are:

[0015] In this application, the light box assembly is installed in the middle of the conveyor belt assembly, and the light source of the light box assembly is facing upward. Since the conveyor belt is made of a light-transmitting material, the light generated by the light box assembly will pass through the conveyor belt. When parts are transported through the light box assembly via the conveyor belt, the parts will block the transmission of light, causing the light to diffuse in space, thereby more completely and clearly reflecting the shape of the parts.

[0016] In this application, when the transmission belt carries the parts through the bottom of the lighting ring, the industrial camera photographs the parts through the through hole. It is worth noting that the light intensity of the light box assembly is less than the light intensity of the lighting ring, which avoids glare caused by the two strong lights irradiating the lens, and the annular light source of the lighting ring provides uniform lighting, which helps the industrial camera to better capture the image of the photographed object. This uniform lighting helps to eliminate shadows and reflections, making the image clearer, thereby improving the quality and clarity of the image. When used in conjunction with the light box assembly, the outline of the photographed part is clearer, which helps the industrial camera to more accurately capture the details and features of the parts when conducting product inspections.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places in this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Furthermore, this utility is described in detail with reference to schematic diagrams. For ease of explanation, the cross-sectional views of the device structures will be partially enlarged and not to scale when describing the embodiments of this utility. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of this utility. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0026] Please see the attached Figure 1-3 As shown, the present invention provides a device for verifying parts and original images after laser cutting, including a conveyor belt assembly 1, and a positioning mechanism 10 and a verification mechanism 2 arranged in sequence on the conveyor belt assembly 1. The parts are transported through the conveyor belt assembly 1 and pass through the positioning mechanism 10 and the verification mechanism 2 in sequence. A light box assembly 9 is provided inside the conveyor belt assembly 1 corresponding to the verification mechanism 2. The verification mechanism 2 includes fixed brackets 3 provided on both sides of the top of the conveyor belt assembly 1, and a light baffle 4 is installed on the fixed bracket 3. A transverse bracket 5 is provided on the top of the fixed bracket 3, and the transverse bracket 5 connects the fixed brackets 3 on both sides, and an industrial camera 6 is fixed to the bottom of the transverse bracket 5.

[0027] See also Figure 2-3 The transmission belt assembly 1 includes two opposite rollers 101, and the rollers 101 at both ends are covered with a transmission belt 102, wherein the transmission belt 102 is a light-transmitting leather layer.

[0028] Specifically, the light box assembly 9 is installed in the middle of the conveyor belt assembly 1, and the light source of the light box assembly 9 is facing upward. Since the conveyor belt 102 is made of a light-transmitting material, the light generated by the light box assembly 9 will pass through the conveyor belt 102. When parts are transported through the light box assembly 9 via the conveyor belt 102, the parts will block the transmission of light, causing the light to diffuse in space, thereby more completely and clearly reflecting the shape of the parts.

[0029] See also Figure 2-3 A bracket 7 is fixedly installed on the side of the fixed bracket 3, and a lighting ring 8 is provided at the bottom of the bracket 7. A through hole 701 is provided on the bracket 7 corresponding to the aperture of the lighting ring 8, and the shooting position of the industrial camera 6 is set corresponding to the through hole 701.

[0030] More specifically, when the transmission belt 102 carries the parts through the bottom of the lighting ring 8, the industrial camera 6 photographs the parts through the through hole 701. It is worth noting that the light intensity of the light box assembly 9 is less than the light intensity of the lighting ring 8, which avoids glare caused by the two strong lights irradiating the lens, and the annular light source of the lighting ring 8 provides uniform lighting, which helps the industrial camera 6 to better capture the image of the photographed object. This uniform lighting helps to eliminate shadows and reflections, making the image clearer, thereby improving the quality and clarity of the image. When used in conjunction with the light box assembly 9, the outline of the photographed part is clearer, which helps the industrial camera 6 to more accurately capture the details and features of the parts when conducting product inspection.

[0031] See also Figure 2-3 The light box assembly 9 includes a support plate 901, which is horizontally mounted on the middle hole of the transmission belt 102. A lighting box 902 is installed on the top of the support plate 901. A lampshade 903 is provided on the top of the lighting box 902, and the top of the lampshade 903 is retracted toward the middle.

[0032] According to the above, the setting of the top of the lampshade 903 being retracted toward the middle allows the lighting box 902 to change the angle of forward projection of light, thereby achieving a focusing effect of light irradiation in a small range, and can concentrate the light on a specific area of the transmission belt 102, thereby highlighting the details and features of the irradiated parts, helping to reduce the unclear edges of the industrial camera 6 when shooting, and helping to improve the accuracy of part detection.

[0033] The working principle of this utility model is as follows: after the laser cutting of the parts is completed, the industrial camera 6 takes a picture. When the industrial camera 6 takes a picture, the lighting box 902 remains on, which improves the clarity of the outline of the part, and helps the industrial camera 6 to more accurately capture the details and features of the part when conducting product inspection. After the picture is taken, it is uploaded to the terminal, and the part is matched with the required original picture. The built-in software of the terminal is used for verification and calculation to check for missing holes, cutting size, and cutting errors, etc.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
