technical field

The invention relates to a support structure, in particular to a combined light source support for machine vision.

Background technique

Inspection systems based on machine vision technology are widely used in industry, agriculture, national defense and other fields. Traditional manual visual inspection of product quality has low efficiency and low precision. Using machine vision inspection methods greatly improves production efficiency and automation of production, and saves management and labor costs for industrial production. A typical machine vision inspection system mainly includes three parts: lighting, lens, and camera. Lighting is an important factor affecting the input of the machine vision system, which directly affects the quality of input data and application effects. At this stage, since there is no general machine vision lighting equipment, it is necessary to select the corresponding lighting device for each specific application instance to achieve the best effect. In the process of selecting a lighting device, multiple factors such as light intensity, power, color, angle, and height must be considered comprehensively. A change in one factor may cause the entire device to be different from the existing device. Therefore, it is often necessary to customize the lighting device to meet Demand, production costs are high and it takes a long time to put into use. The non-universal nature of lighting devices hinders the development of machine vision inspection systems to a certain extent.

Combined light source bracket for machine vision.

The technical solution of the present invention is: a combined light source bracket for machine vision, including a frame body 1, characterized in that: the frame body 1 is a cross-shaped frame structure, including a central part 2 and four protruding parts 3. There are also two connecting ribs 4 symmetrically arranged on the frame body 1, and the connecting ribs 4 are respectively connected with two adjacent protruding parts 3, and a supporting sleeve 5 is arranged below the connecting ribs 4, and the supporting sleeve 5 The inner movable sleeve is provided with a support column 6, the bottom end of the support column 6 is provided with a bending type support frame 7, and the surface of the support column 6 is also provided with a scale line 8, and the support sleeve 5 is also provided with a 6. Matching locking screws 9 rotate and support a plurality of mutually parallel lamp bead strips 10 in each protruding part 3, and a plurality of LED lamp beads 11 are equidistantly arranged in the lamp bead strips 10, All the LED lamp beads 11 are connected to the positive pole 12 and the negative pole 13 arranged at the two ends of the lamp bead strip 10 through wires, the positive pole 12 is one, and the negative pole 13 is two symmetrically arranged. The inner side of the part 3 is provided with a plurality of pairs of slots 14 matching the lamp bead strip 10 , and the slots 14 can rotate along their own axes, and an angle dial 15 is also provided on the slots 14 .

Compared with the prior art, the present invention has the following advantages:

The combined light source bracket for machine vision with this structure has simple structure, ingenious design, and reasonable layout. It can choose different quantities, different colors, and different powers of lamp bead strips to insert into the socket of the frame according to different product testing requirements. In the groove, different irradiation angles and irradiation heights can be precisely adjusted at the same time, which is convenient and flexible, and the adjustment is simple and accurate; it can be applied to the requirements of various product inspections, greatly improving the scope and flexibility of the machine vision lighting device; and The device also has multiple advantages such as low cost, stable operation, and simple operation, and is very suitable for large-scale promotion in the field of machine vision lighting.

detailed description

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Figure 1, Figure 2, and Figure 3: a combined light source bracket for machine vision, including a frame body 1 as a base, the frame body 1 is a cross-shaped frame structure, including a center in the middle Part 2 and four protruding parts 3 are also symmetrically provided with two connecting ribs 4 on the frame body 1, and each connecting rib 4 is fixedly connected with two adjacent protruding parts 3 respectively. 4 is provided with a support sleeve 5 below, and a support column 6 is movably socketed in the support sleeve 5, and a bending type support frame 7 for supporting the whole device is provided at the bottom of the support column 6. The surface is also provided with a scale line 8, and on the support sleeve 5, a tightening screw 9 matching the above-mentioned support column 6 is threaded;

A plurality of lamp bead strips 10 are rotatably supported in each protruding part 3, and these lamp bead strips 10 are parallel to each other, and a plurality of LED lamp beads 11 are equidistantly arranged in each lamp bead strip 10, And all the LED lamp beads 11 are connected to the positive pole 12 and the negative pole 13 arranged at both ends of the lamp bead bar 10 through wires, and in order to prevent reverse installation, the above-mentioned positive pole 12 is one, while the negative pole 13 is arranged symmetrically Two pairs of slots 14 are provided on the inner side of the protruding part 3. The above-mentioned lamp bead strip 10 can be inserted into the slots 14, and the slots 14 can rotate along their own axes, that is, when the lamp beads After the strip 10 is inserted into the slot 14 , the lamp bead strip 10 can rotate along its own axis, and the slot 14 is also provided with an angle dial 15 .

The working process of the combined light source bracket for machine vision in the embodiment of the present invention is as follows: the color, power and quantity of the lamp bead strips are selected in advance according to the lighting requirements of the machine vision. For example, determine the lighting scheme of white, 3W, 3×4=12 lamp bead strips according to the needs. That is, install 12 white, 3W LED lamp bead strips on the frame body 1, and place the frame body 1 of this bracket in an environment that needs to provide lighting. By adjusting the relative position of the support sleeve 5 and the support column 6, the height of all the lamp bead strips 10 (that is, the light source) can be changed, and by rotating the lamp bead strip 10, the height of all the lamp bead strips 10 (that is, the light source) can be changed At the same time, since the scale line 8 is set on the support column 6, and the angle dial 15 is set on the slot 14, the operator can accurately perform the above adjustments; after turning on the power, 12 white, 3W LEDs The lamp bead strip 10 emits light to provide a light source for the machine vision system;

Moreover, since all the light bead strips 10 have one positive pole 12 and two negative poles 13, this special structure can effectively prevent reverse installation when the light bead strip 10 is installed.
