Description

Technical Field

[0001] This utility model relates to the field of cable tray processing technology, and in particular to a visual inspection device for cable trays. Background Technology

[0002] Cable trays are a general term for a continuous, rigid structural system consisting of trays, straight sections of ladders, bends, accessories, supports, and hangers, used to support cables.

[0003] After production, cable trays need to undergo visual inspection to avoid affecting their appearance; however, cable trays vary in size, especially large cable trays exceeding 1 meter, which result in longer transfer times and shorter visual inspection times, thus slowing down the overall production cycle.

[0004] Patent application number 202110469189.9 discloses a visual inspection device for cable trays. By setting up a moving mechanism and a measuring mechanism, the moving mechanism drives the measuring mechanism to move and measure the length of the cable tray. Furthermore, by setting up a ventilation mechanism, a limiting mechanism, and a diameter measuring mechanism, when the moving mechanism drives the limiting mechanism to an opening under negative pressure, the movable part in the limiting mechanism moves towards the opening under the negative pressure, pulling the latch to move. This causes the latch to no longer obstruct the diameter measuring mechanism, allowing the diameter measuring mechanism to fall into the opening under negative pressure, thereby measuring the diameter of the opening. By observing the measurement results of the measuring mechanism and the diameter measuring mechanism, the operator can obtain the length measurement result of the cable tray and the opening diameter measurement result, and determine whether the quality of the cable tray meets the standards. Compared with existing manual measurement methods, this device improves the degree of automation and saves manpower.

[0005] Although the above-mentioned device can automatically inspect cable trays, it only has one set of industrial cameras, requires frequent movement of the cable trays for inspection, and has a complex structure and is cumbersome to operate.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a visual inspection device for cable trays that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A visual inspection device for cable trays includes: an intermittent feeding line and a vision component for inspecting the cable trays;

[0010] The vision component includes: a mounting frame, a receiving line, and a first camera; the first camera is fixedly mounted on a rotating plate, the rotating plate is connected to a rotary cylinder that drives it to rotate, the rotary cylinder is connected to a first cylinder that drives it to rise and fall, and the first cylinder is connected to a second cylinder that drives it to rise and fall.

[0011] Furthermore, a push cylinder is mounted on the rotating part, and a second camera is fixedly connected to the piston shaft of the push cylinder.

[0012] Furthermore, the receiving line includes: a belt conveyor, a moving rod, and a power source. The belt conveyor is mounted on the moving rod, and the power source drives the moving rod to move.

[0013] Furthermore, the power source includes: a first motor, a ball screw connected to the output shaft of the first motor, a slider connected to the ball screw, and the slider being fixedly connected to the moving rod.

[0014] Furthermore, the belt conveyor is divided into a left belt conveyor and a right belt conveyor, which are connected by a connecting shaft. The end of the connecting shaft is threaded to the left and right belt conveyors, and a second motor that drives them to rotate is connected to the connecting shaft.

[0015] Furthermore, the intermittent feeding line is divided into two and is located on both sides of the vision component.

[0016] Compared with the prior art, the present invention has the following advantages: when testing is required, the intermittent feeding line on one side feeds the material while the intermittent feeding line on the other side feeds the material, which can significantly increase the production cycle. If the cable tray is too large, the first camera can be inserted into the fixed frame to avoid damage to it by the cable tray. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] The following is a clear and complete description of a cable tray visual inspection device according to the present invention, with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, this utility model discloses a visual inspection device for cable trays, comprising: an intermittent feeding line 1 and a visual component 2 for inspecting cable trays; the intermittent feeding line 1 is divided into two parts and is disposed on both sides of the visual component 2; when inspection is required, one side of the intermittent feeding line 1 feeds material and the other side of the intermittent feeding line 1 unfeeds material, which can significantly increase the production cycle.

[0026] The vision component 2 includes: a fixed frame 3, a receiving line 4, and a first camera 5; the first camera 5 is fixedly mounted on a rotating plate 6, and a rotary cylinder 7 is connected to the rotating plate 6 to drive its rotation, a first cylinder 8 is connected to the rotary cylinder 7 to drive its lifting and lowering, and a second cylinder 9 is connected to the first cylinder 8 to drive its lifting and lowering.

[0027] It should be explained in detail here that the second cylinder 9 is fixedly installed on the fixed frame 3, the piston rod of the second cylinder 9 is connected to the first lifting plate 10, the first cylinder 8 is installed on the first lifting plate 10; the piston rod of the first cylinder 8 is fixedly installed on the second lifting plate 11, and the rotary cylinder 7 is fixedly installed on the second lifting plate 11.

[0028] The first camera 5 moves in a direction perpendicular to the receiving line 4. If the bridge is too large, the first camera 5 can penetrate into the fixed frame 3 to avoid damage to it.

[0029] A push cylinder 12 is mounted on the rotating part, and a second camera 13 is fixedly connected to the piston shaft of the push cylinder 12. The push cylinder 12 can drive the second camera 13 to move, so that the second camera 13 can monitor the cable tray on the other side and avoid the edge of the cable tray from colliding with this application.

[0030] It should be noted here that, since the feeding is intermittent, the vision component 2 needs to take into account the intermittent feeding lines 1 on both sides. Therefore, the receiving line 4 must be movable so that it can approach the intermittent feeding lines 1 on both sides respectively.

[0031] The receiving line 4 includes: a belt conveyor 14, a moving rod 15, and a power source. The belt conveyor is installed on the moving rod 15, and the power source drives the moving rod 15 to move. The power source includes: a first motor 16, a ball screw 17 connected to the output shaft of the first motor 16, and a slider connected to the ball screw 17. The slider is fixedly connected to the moving rod 15.

[0032] When the output shaft of the first motor 16 drives the ball screw 17 to rotate, the slider moves accordingly, thereby causing the moving rod 15 to move, which in turn drives the receiving line 4 to move closer to the intermittent feeding line 1 on either side.

[0033] To accommodate cable trays of different widths, the spacing of the belt conveyors can be adjusted. The belt conveyors are divided into a left belt conveyor and a right belt conveyor, which are connected by a connecting shaft 18. The end of the connecting shaft 18 is threaded to the left and right belt conveyors, and a second motor 19 is connected to the connecting shaft 18 to drive its rotation. That is, when the second motor 19 rotates, it drives the connecting shaft 18 to rotate, thereby causing the left and right belt conveyors to move.

[0034] It should be noted that guide mechanisms are installed below the left and right belt conveyors, as shown in the attached diagram.

[0035] Finally, it should be noted that the intermittent conveyor line 1 can also be adapted to cable trays of different widths. Its principle is the same as that of the belt conveyor, and will not be elaborated here.

[0036] When this application requires testing, material is fed onto one side of the intermittent feeding line 1 and unloaded onto the other side of the intermittent feeding line 1. When the output shaft of the first motor 16 drives the ball screw 17 to rotate, the slider moves accordingly, thereby causing the moving rod 15 to move, which in turn drives the receiving line 4 to move closer to either side of the intermittent feeding line 1.

[0037] The lifting design of the first camera 5 allows it to be inserted into the mounting bracket 3 when not in use, preventing damage to it.

[0038] The various modifications described in these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
