Description

Technical Field

[0001] The utility model belongs to the technical field of visual inspection equipment, and particularly relates to a detection device for assembled precast components. Background Technique

[0002] An assembled precast component is a concrete component precast in a mold using concrete, and can be used as the main structures such as beams, slabs, and columns for building construction. Assembled precast components are commonly used in the construction of buildings such as residences and factories, which can shorten the construction period of buildings and are more low-carbon and environmentally friendly.

[0003] During actual production and manufacturing, affected by factors such as raw materials, time, temperature, environment, and equipment, surface quality defects such as exposed steel bars, surface honeycombing, slag inclusion, holes, and cracks are likely to occur in assembled precast components. In order to ensure the quality of products leaving the factory, after the production of precast components is completed, it is necessary to detect the appearance of the products.

[0004] In terms of appearance quality inspection, currently, most of them detect whether the surface of precast components is flat and smooth through manual visual inspection. This inspection method largely depends on the experience and judgment of inspectors, and is greatly affected by human factors. It not only consumes a large amount of time and manpower, but also is extremely prone to missed inspections, resulting in the outflow of unqualified products. Content of the Utility Model

[0006] To achieve the above object, the technical solution adopted by the utility model is: to provide a detection device for assembled precast components, including:

[0007] A conveying assembly, including two conveying mechanisms, the two conveying mechanisms are arranged at intervals along the first horizontal direction, and the conveying direction of the conveying mechanism is parallel to the first horizontal direction;

[0008] A first detection assembly, including two transverse movement mechanisms, and two first detection mechanisms respectively arranged on the two transverse movement mechanisms.

The lead screw is rotatably arranged in one of the first sliding grooves, and the first detection mechanism is in threaded engagement with the lead screw.

The detection chamber covers the outside of the first detection component and the second detection component. The detection chamber has a feeding channel that penetrates along the first horizontal direction. In the feeding direction, the discharging end of the previous conveying mechanism and the feeding end of the next conveying mechanism are respectively accommodated in the feeding channel.

[0019] In a possible implementation, a supplementary light is further provided on the mounting plate, and the supplementary light is disposed on one side of the camera.

[0040] Compared with the prior art, the beneficial effects of the assembly - type precast component detection device 1 provided by the embodiment of the present utility model are as follows:

[0041] The assembly - type precast component detection device 1 provided by the embodiment of the present utility model includes a conveying assembly, a first detection assembly 20 and a second detection assembly 30. The conveying assembly can convey the precast component 50 to be detected along the first horizontal direction. When the precast component passes through the first detection assembly 20, the two first detection assemblies 20 arranged vertically relative to each other can respectively take pictures of the upper surface and the lower surface of the precast component. When the precast component passes through the second detection assembly 30, the two second detection mechanisms 32 arranged horizontally relative to each other can take pictures of the left and right side surfaces of the precast component. When the size of the precast component is large, the transverse movement mechanism 21 can drive the first detection mechanism 22 to move left and right, and the longitudinal movement mechanism 31 can drive the second detection mechanism 32 to move up and down, so as to facilitate photographing each part of the precast component, and the adjustment is convenient. The first detection mechanism 22 and the second detection mechanism 32 transmit the captured image information to the processing software, and the processing software analyzes and judges the appearance of each side surface of the precast component, and accordingly judges whether there are defects such as exposed steel bars and cracks on the surface of the precast component. Compared with the manual visual inspection method, it saves more manpower and is not easy to cause missed inspection, which helps to ensure the quality of the products leaving the factory. The processing software can directly select the existing image recognition system on the market.

[0042] In the embodiment of the present utility model, the conveying assembly includes two conveying mechanisms 10 connected end to end. The two conveying mechanisms 10 are arranged at intervals to leave a space for the first detection mechanism 22 located below to take pictures, so that the first detection mechanism 22 can take pictures of the lower surface of the precast member.

[0043] The conveying mechanism 10 can be a roller conveyor. The roller conveyor includes a plurality of conveying rollers 11 arranged at intervals in the first horizontal direction. The plurality of conveying rollers 11 rotate synchronously through forms such as chain drive and gear drive, and can convey the precast member along the direction indicated by the arrow. Or, in some possible embodiments, the conveying mechanism 10 can also be a chain plate conveyor, a belt conveyor or a robotic arm arranged in the first horizontal direction, as long as it can drive the precast member 50 to be detected to move along the conveying direction. Figure 1 The first detection assembly 20 includes two transverse movement mechanisms 21 and two first detection mechanisms 22. The transverse movement mechanism 21 is used to install the first detection mechanism 22 and can drive the first detection mechanism 22 to reciprocate along the transverse movement track 211 to take pictures of different positions of the precast member. The second detection assembly 30 is the same as the first detection assembly 20, except that it is vertically arranged. Both the first driving member 212 and the second driving member 312 can achieve linear reciprocating motion, specifically, an electric telescopic rod, a telescopic cylinder, etc. arranged along their own movement directions.

The operation of the conveying assembly, the first detection assembly 20 and the second detection assembly 30 can be automatically controlled by a PLC control program, or can be controlled by an operator through a controller, remote control, handle, etc.

[0045] The first detection mechanism 22 and the second detection mechanism 32 are used to obtain the surface image of the precast member 50 to be detected. The first detection mechanism 22 and the second detection mechanism 32 can adopt existing industrial cameras 222 on the market, which can transmit the taken images to the analysis software, and the analysis software judges whether the surface quality of the precast member is qualified. There is no limit to the specific specifications and models of the first detection mechanism 22 and the second detection mechanism 32, as long as they can meet the use requirements.
