Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to an automated auxiliary calibration fixing device. Background Technology

[0002] Currently, in the field of automation, the integration with vision has become a common phenomenon. In applications, vision plays a guiding and positioning role, just like human eyes, guiding robots and other automated facilities to different positions according to needs, and doing so more accurately and reliably, playing an important role.

[0003] However, before using vision instruments, they need to be calibrated to ensure accuracy. But in most automated applications currently on the market, the calibration plate is not assigned a fixed position; calibration is performed at any random location. Furthermore, because there is no fixed position, the calibration plate is easily lost over time, and arbitrary movement can deform it, thus affecting the accuracy of the calibration. Utility Model Content

[0004] The main purpose of this invention is to propose an automated auxiliary calibration fixing device, which overcomes the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] An automated auxiliary calibration fixing device includes: a calibration plate mounting plate, which is rectangular in shape. Four parallel support columns are set at the four corners of one side, and positioning blocks are set near the four corners of the other side. The calibration plate is set in the middle of the four positioning blocks, and the positioning blocks are precisely locked in the four corners of the calibration plate. Fixing blocks are connected to the positioning blocks to fix the calibration plate. The ends of the four support columns away from the calibration plate mounting plate are connected to a bottom mounting fixing plate. Parallel mounting grooves are set on the opposite two edges of the bottom mounting fixing plate.

[0007] Furthermore, the support column includes a first support column and a second support column, the first support column being longer than the second support column, the two first support columns being distributed on the same side, and the two second support columns being distributed on the same side.

[0008] Furthermore, the bottom mounting plate is perpendicular to the support column and forms an angle with the calibration plate mounting plate.

[0009] Furthermore, the connection between the calibration plate mounting plate and the support column is a detachable connection.

[0010] Furthermore, the connection between the positioning block and the calibration plate mounting plate is a detachable connection.

[0011] Furthermore, the fixing block and the positioning block are detachably connected.

[0012] Furthermore, the bottom mounting plate and the support column are detachably connected.

[0013] This invention solves the problem that existing equipment calibration plates are easily lost, frequently moved, and easily deformed, thus affecting the calibration accuracy of the equipment. Through precise positioning and firm fixing, this application effectively reduces calibration errors caused by external factors such as vibration and impact, ensuring the calibration accuracy of the equipment under various environmental conditions.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] The following is for reference. Figures 1 to 2 The present invention will be further described below:

[0022] An automated auxiliary calibration fixing device includes: a calibration plate mounting plate 1, which is rectangular in shape. Four parallel support columns 2 are provided at the four corners of one side, and positioning blocks 3 are provided near the four corners of the other side. A calibration plate 4 is provided in the middle of the four positioning blocks 3. The positioning blocks 3 fit into the four corners of the calibration plate 4. Fixing blocks 5 are connected to the positioning blocks 3 to fix the calibration plate 4. A bottom mounting fixing plate 6 is connected to the end of the four support columns 2 away from the calibration plate mounting plate 1. Mounting grooves 7 are provided on the two opposite edges of the bottom mounting fixing plate 6.

[0023] In this embodiment, four positioning blocks 3 form a rectangular area, with a calibration plate 4 placed in the center. The positioning blocks 3 precisely lock the four corners of the calibration plate 4, fixing its position. The fixing blocks 5 are bolted to the positioning blocks 3 to ensure the calibration plate 4 remains stable. The support column 2 is also bolted to the bottom mounting plate 6.

[0024] The mounting slot 7 allows the position of the bottom mounting plate 6 to be adjusted within a certain range, thus adapting to various sizes and layouts of automated installation platforms.

[0025] Furthermore, the support column 2 includes a first support column 21 and a second support column 22. The length of the first support column 21 is greater than that of the second support column 22. The two first support columns 21 are distributed on the same side, and the two second support columns 22 are distributed on the same side.

[0026] The support column 2 is designed in two lengths: the first support column 21 is longer and the second support column 22 is shorter. The first support column 21 is located on one side of the device, while the second support column 22 is located on the other side. This design creates an inclined angle between the bottom mounting plate and the calibration plate mounting plate, which is beneficial for calibration work.

[0027] In this embodiment, the bottom mounting plate 6 is perpendicular to the support column 2 and forms an inclined angle with the calibration plate mounting plate 1, ranging from 0° to 90°. This design not only increases the stability of the device but also facilitates line-of-sight adjustment and operational convenience during the calibration process. The selection of the inclined angle is based on the calibration requirements and operating space considerations in practical applications, ensuring that the device meets both accuracy requirements and ease of operation.

[0028] In one optional embodiment, the calibration plate mounting plate 1 and the support column 2 are connected by a slot-type detachable connection. The calibration plate mounting plate 1 has a slot that matches the shape of the support column 2, and the bottom of the support column 2 has a protrusion that mates with the slot, allowing for simple insertion to complete the connection. This connection method requires no tools, facilitates quick assembly and disassembly, and improves the flexibility and efficiency of the device.

[0029] Furthermore, the connection between the positioning block 3 and the calibration plate mounting plate 1 is a detachable connection.

[0030] In one optional embodiment, the positioning block 3 and the calibration plate mounting plate 1 are connected by a magnetic detachable connection. A strong magnet is embedded in the calibration plate mounting plate 1, and a metal plate attracted to the magnet is located at the bottom of the positioning block 3. This connection method is not only stable and reliable, but also allows for quick replacement or adjustment of the position of the positioning block 3 when needed, meeting the requirements of different calibration plate sizes and shapes.

[0031] In one optional embodiment, the fixing block 5 and the positioning block 3 are connected by a snap-fit ​​detachable connection. The fixing block 5 has a spring-loaded snap on one side, and the positioning block 3 has a matching slot. The fixing block 5 and the positioning block 3 can be connected and disconnected simply by pressing and rotating. This connection method is simple and easy to implement, requires no additional tools, and facilitates the quick fixing and releasing of the calibration plate 4 during calibration.

[0032] In one optional embodiment, the bottom mounting plate 6 and the support column 2 are connected by threads. The top of the support column 2 has external threads, and the bottom mounting plate 6 has threaded holes that match the threads. By rotating the support column 2, a tight connection between the bottom mounting plate 6 and the support column 2 can be achieved. This connection method is not only stable and reliable, but also allows the height and angle of the bottom mounting plate 6 to be adjusted according to actual needs, improving the adaptability and flexibility of the device.
