Description

Technical Field

[0001] This utility model relates to the field of vision equipment technology, specifically a camera light source mounting bracket installed at the end of a robot. Background Technology

[0002] Currently, in the automated manufacturing industry, vision inspection projects for specific application scenarios all require robots to be equipped with vision light sources and industrial camera components. Application scenarios refer to hand-eye calibration in two ways: eye-in-hand and eye-to-hand. In actual applications, cameras can also be used in a similar manner to eye-in-hand, where the camera is mounted on the robot's end flange and moves with the robot to take pictures.

[0003] Currently, in order to ensure the strength of the camera bracket and avoid the camera shaking during robot movement from affecting the accuracy of the detection results, machined metal parts are often used as the mounting brackets for the camera and light source in industry. However, compared with the consumables commonly used in 3D printing such as PLA and PETG, even aluminum alloy, a relatively light material in machining, appears to have a very high density (and is very heavy for the same volume).

[0004] As an emerging technology, 3D printing has the advantage of being able to quickly produce and manufacture products, thereby saving time and costs. Especially in the early demonstration stage of making camera brackets for machine vision exhibition areas or vision application solutions, since integrated equipment is not yet mass-produced, 3D printing technology can be customized without requiring a lot of time and cost, and the advantages of printing are highlighted.

[0005] However, the problem with applying 3D printing technology to bracket manufacturing is that 3D printing materials have a certain degree of elasticity, especially for slender structures like support rods, which can easily cause wobbling. Therefore, the camera mounting bracket structures currently on the market are all based on machined metal parts. Utility Model Content

[0006] The purpose of this invention is to provide a camera light source mounting bracket suitable for 3D printing, which provides stable support for the camera and light source.

[0007] The present invention adopts the following technical solution: a camera light source mounting bracket, comprising a camera mounting plate and a light source mounting plate that are positioned opposite each other, the camera mounting plate and the light source mounting plate being fixedly connected by multiple support rods, and a flange adapter plate being fixedly connected to the camera mounting plate; a ring light source is mounted on the light source mounting plate, and a camera is mounted on the camera mounting plate, with the camera lens facing the central gap of the ring light source.

[0008] Preferably, the flange adapter plate includes an adapter plate with connection holes for connecting an industrial robot flange; multiple adapter uprights perpendicular to the adapter plate are fixed around the adapter plate, with connection holes for connecting a camera mounting plate and grooves for installing support rods.

[0009] Preferably, the adapter plate is in the shape of an isosceles trapezoid or an isosceles triangle, and the adapter plate is perpendicular to the plane of the industrial robot flange; the groove is formed at the center of the axis of symmetry of the adapter plate and is perpendicular to the plane of the industrial robot flange.

[0010] Preferably, the camera mounting plate includes a camera mounting plate with a cross-shaped opening in the middle and connection holes for mounting a camera. Multiple camera mounting uprights perpendicular to the camera mounting plate are fixed around the periphery of the camera mounting plate, the number of which is equal to the number of adapter uprights. Each camera mounting upright has connection holes for connecting adapter uprights and connection holes for connecting support rods.

[0011] Preferably, the light source mounting plate includes a light source mounting frame, on which a connecting hole for connecting a ring light source is provided; multiple light source mounting uprights perpendicular to the light source mounting frame are fixed around the perimeter of the light source mounting frame, the number of light source mounting uprights being equal to the number of adapter uprights; the light source mounting uprights are provided with connecting holes for connecting support rods.

[0012] Preferably, the support rod is provided with multiple connection holes for connecting the light source mounting plate.

[0013] Preferably, the light source mounting plate is an isosceles triangle and has a hollow structure.

[0014] Preferably, the flange adapter plate is connected to one side of the mounting block, and the other side of the mounting block is mounted on the industrial robot flange.

[0015] Preferably, the mounting block is a square pyramid or a pentagonal pyramid.

[0016] The advantages of this utility model are as follows: the design of each component of the mounting bracket reduces the amount of suspension, making it suitable for 3D printing, easy to process, with a short production cycle, low cost, and easy to assemble; at the same time, the use of triangular stability design in multiple places improves the overall structural strength and avoids the problem of camera and light source shaking caused by the movement of the robot end effector.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Combination Figure 1 and Figure 2As shown, a camera light source mounting bracket has a flange adapter plate 1 fixedly connected to the upper side of a camera mounting plate 2. A light source mounting plate 4 is positioned vertically opposite the camera mounting plate 2, and the two are fixedly connected by multiple support rods 3. Both ends of the support rods 3 are bolted to both the camera mounting plate 2 and the light source mounting plate 4. A ring light source is mounted on the light source mounting plate 4, and a camera is mounted on the camera mounting plate 2, with the camera lens facing the central gap of the ring light source. In this embodiment, the ring light source includes: typical ring light sources commonly found in industrial light sources; high-brightness ring light sources, semi-ring light sources, and ring shadowless light sources derived from ring light sources; and strip-shaped combined light sources, square shadowless light sources, and four-sided shadowless light sources with similar ring light source structures. The ring light source and the camera are mounted on the same side of the object being photographed, with the center of the ring light source allowing the lens's field of view to pass through.

[0031] Combined Figure 3 and Figure 4 As shown, the flange adapter plate 1 includes an adapter plate 11, which has connection holes for connecting an industrial robot flange. The adapter plate 11 is square, and each of its three sides has an adapter vertical plate 12 perpendicular to the adapter plate 11. In this embodiment, the fourth side of the adapter plate 11 does not have an adapter vertical plate 12, because having only three sides with adapter vertical plates 12 already constitutes a stable structure, and leaving a fourth side facilitates installation. The adapter vertical plate 12 is an isosceles trapezoid, and a groove 13 for installing a support rod 3 is provided at the center of the axis of symmetry of the adapter vertical plate 12. The direction of the groove 13 is perpendicular to the adapter plate 11. The adapter vertical plate 12 has connection holes for connecting a camera mounting plate 2, and the number of these connection holes is not less than two and they are symmetrically arranged about the axis of symmetry of the adapter vertical plate 12.

[0032] The camera mounting plate 2 includes a square camera mounting plate 21 with a cross-shaped opening in the center. This cross-shaped opening saves 3D printing materials and provides space for camera heat dissipation. The camera mounting plate 21 has connection holes for mounting the camera, the position and size of which correspond to the mounting holes on the camera, and the two are connected by bolts. The camera mounting plate 21 is parallel to the adapter plate 11, and three sides of the camera mounting plate 21 each have camera mounting uprights 22 perpendicular to it. The camera mounting uprights 22 are fitted to the inner side of the adapter uprights 12, and the camera mounting uprights 22 have connection holes for connecting to the adapter uprights 12, which are opposite to the connection holes on the adapter uprights 12, and the two are connected by bolts.

[0033] The light source mounting plate 4 includes a light source mounting frame 41. The light source mounting frame 41 has connecting holes for connecting a ring light source. The position and size of these connecting holes correspond to the mounting holes on the ring light source, and the two are connected by bolts. The light source mounting frame 41 is parallel to the camera mounting plate 21, and each of the three sides of the light source mounting frame 41 has a light source mounting stand 42 perpendicular to the light source mounting frame 41. The light source mounting stand 42 is an isosceles triangle with a hollow structure. Since the mass of a light source is generally much smaller than that of a camera or lens, vibrations generated during robot movement are unlikely to cause the light source to shake. Therefore, the light source mounting stand 42 can use a hollow triangular support to reduce the weight of the support and save printing consumables.

[0034] The support rods 3 are straight rods, and there are three in total. The upper end of each support rod 3 has a connecting hole, and the upper end of each support rod 3 is fitted into a groove 13 in the adapter plate 12. The camera mounting plate 22 has through holes corresponding to the connecting holes at the upper end of the support rods 3, and the upper end of the support rods 3 is connected to the camera mounting plate 22 by bolts. Several sets of connecting holes are arranged in an array at the lower end of each support rod 3, with equal spacing between the connecting holes. The light source mounting plate 42 has through holes corresponding to the connecting holes at the lower end of the support rods 3, and the lower end of the support rods 3 is connected to the light source mounting plate 42 by bolts. Because the connecting holes at the lower end of the support rods 3 can be selected for use, the distance between the light source mounting position and the camera can be adjusted appropriately.

[0035] Example 2

[0036] Combination Figure 5 As shown, the difference in this embodiment compared to the first embodiment described above is that:

[0037] The flange adapter plate 1 is connected to the industrial robot flange via a mounting block 5. In this embodiment, the mounting block 5 is a four-sided pyramid. One side of the mounting block 5 is mounted on the industrial robot flange, and the other sides of the mounting block 5 can be connected to the flange adapter plate 1, allowing multiple supports to be mounted on one mounting block 5. By rotating the industrial robot flange, different supports and tools can be selected, enabling free switching of tools.

[0038] The camera light source mounting bracket disclosed in this utility model is suitable for 3D printing. Each component meets the requirement that 3D printed parts should start from the bottom surface as much as possible and reduces the amount of suspension. At the same time, the stability of triangles is used in many places, and the bracket has sufficient strength to prevent the camera and light source from shaking due to mechanical movement. In non-mass production, compared with the machining of the bracket, the use of 3D printing can greatly reduce the production cost and processing speed of the bracket.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
