Description

Technical Field

[0001] The present invention relates to the technical field of material fluidity detection, and specifically, to an automatic test detection device for the fluidity of cement paste. Background Art

[0002] By analyzing and comparing the data results of the cement paste fluidity test, the influence of different proportion components and admixtures in the cement on the cement performance can be reflected. Therefore, the change of the cement paste fluidity has certain significance for determining reasonable process parameters, saving costs, and ensuring the quality of cement products and formed concrete products. In the enterprise production practice, whether it is to detect the performance of cement and admixtures or to collect data for new product development, the cement paste fluidity test needs to be carried out repeatedly. During the test process, although the stirring process does not require manual operation, the processes of weighing ingredients, operating necessary devices, and measuring and sorting data all need on-site manual operation. On the one hand, this kind of work requires operators to have a high level of knowledge reserve and relatively delicate operation, and at the same time, its essence is boring and repetitive labor, and the experience and new knowledge obtained by the operators can be basically ignored. Therefore, manual operation is a huge waste of human resources and has an adverse impact on the innovation enthusiasm and long-term development of the operators.

Therefore, there is an urgent need for an automatic test detection device for the fluidity of cement paste to realize the full-automatic experimental detection of the fluidity of cement paste to liberate the operators and reduce uncontrollable variables, so as to ultimately improve the efficiency and accuracy of test detection.

Without departing from the above technical idea of the present invention, various substitutions or changes made according to ordinary technical knowledge and conventional means in the art should be included within the scope of the present invention.

[0036] Example 1:

[0037] This example provides an automatic test and detection device for the fluidity of neat cement. As Figures 1-4 shown, the test and detection device includes:

[0038] Placement rack 01, which is used to place the stirring funnel and stirring blades to be installed;

[0039] Batching machine 02, which is used to quantitatively mix the components of neat cement and then inject them into the stirring funnel;

[0040] Mixer 03, which has a drive motor 031 and a lifting mounting seat 032. The drive motor 031 for installing and driving the stirring blades to rotate is located directly above the lifting mounting seat 032, and the lifting mounting seat 032 for installing and fixing the stirring funnel can move up and down;

[0041] An operating platform 04, on which a glass lifting and storing mechanism 05 and a glass handling device 06 are installed, and the upper surface of the operating platform 04 is horizontally arranged;

[0042] The glass lifting and storage mechanism 05 comprises a power mechanism 051 and two lifting mechanisms 052. The two longitudinally arranged lifting mechanisms 052 vertically penetrate the operating platform 04 and are in transmission connection with the power mechanism 051 fixedly mounted on the bottom surface of the operating platform 04 to achieve synchronized vertical movement of the two lifting mechanisms 052. The two lifting mechanisms 052 are each provided with a plurality of supporting portions 0521 equidistantly spaced in the vertical direction. The two supporting portions 0521 located at the same height on two different lifting mechanisms 052 are respectively used to support the left and right edges of the same glass plate 053.

[0043] The glass handling device 06 includes a handling clamp located on the upper surface of the glass handling platform and a linear track embedded in the operating platform 04 for driving the handling clamp. The handling clamp is used to horizontally move the glass plate 053 placed on the upper surface of the operating platform 04.

[0044] A truncated cone conveying mechanism 07, which is used to convey the truncated cone circular mold to approach the operating platform 04;

[0045] A push rod mechanism 08, which is used to push the truncated cone circular mold on the truncated cone conveying mechanism 07 to the upper surface of the operating platform 04;

[0046] Manipulator 09, the manipulator 09 is used to clamp and move the stirring blade, stirring funnel and truncated cone mold, and install and replace the stirring blade and stirring funnel;

[0047] A CCD camera 10 is located directly above the operating platform 04 , with its camera head facing the center of the glass plate 053 to scan and image the cement paste on the glass plate 053 ;

[0048] An image acquisition card, which is used to acquire the image captured by the CCD camera 10 and save and transmit it in the form of a data file;

[0049] An industrial computer is used to receive data files transmitted by the image acquisition card for data acquisition and calculation, and to set the operating parameters of the batching machine 02, the mixer 03, the glass lifting and storage mechanism 05, the glass handling device 06, the truncated cone conveying mechanism 07, the push rod mechanism 08, the manipulator 09, the CCD camera 10, and the image acquisition card.

[0050] Through the mutual cooperation of various mechanisms, the cement paste fluidity test detection can be achieved in batches in this embodiment, with a high degree of automation, which helps to improve labor efficiency and avoid repetitive labor of operators; at the same time, it reduces various uncontrollable operation errors introduced due to many manual operation links, and helps to improve the test detection efficiency and accuracy.

[0051] Embodiment 2:

[0052] This embodiment is further realized on the basis of Embodiment 1. As Figure 4 shown, a number of scale lines are provided on the upper surface of the glass plate 053, and the centers of each of the scale lines are on the upper surface center of the glass plate 053, and the included angles formed by adjacent scale lines are equal.

[0053] Furthermore, a number of concentric circular lines are provided on the upper surface of the glass plate 053, and the centers of the circular lines coincide with the center of the upper surface of the glass plate 053.

[0054] Furthermore, it includes a top light source, and the top light source is located above the operation platform 04 to illuminate the glass plate 053 placed on the upper surface of the operation platform 04.

[0055] Furthermore, as Figure 2 shown, the operation platform 04 has a light-transmitting area 041, the linear track connects the light-transmitting area 041 on the operation platform 04 and the location where the glass lifting and storage mechanism 05 is provided, and the handling clamp moves along the linear track, so that the glass plate 053 can be moved from the glass lifting and storage mechanism 05 to the light-transmitting area 041; a bottom light source is provided below the light-transmitting area 041. When irradiating from below, the contrast between the flow area of the cement paste on the glass plate 053 and other areas in the picture taken by the CCD camera 10 is stronger. When the industrial computer processes such a picture, it is easier to identify the boundary of the flow area of the cement paste, and both the processing time and computing power required to obtain data can be reduced.

[0056] Scale lines are set on the glass plate 053, which can conveniently measure the flow distance of the edge of the cement paste on the glass plate 053. A large number of photos taken at regular intervals by the CCD camera 10 during the flow process of the cement paste can intuitively display the flow process; the function of the circumferential line is similar to that of the scale line. By controlling the radius of the circumferential line, it is possible to conveniently set in advance the gravity slump area and the planar flow area located at the center according to experience, so that the photos taken by the CCD camera 10 have better reference when observed; at the same time, when the industrial computer processes the image data, the imaging of the scale line and the circumferential line can form a reference, which can weaken the error interference caused by the imaging quality of the CCD camera 10 itself; therefore, the requirements for the imaging quality of the CCD camera 10 can be reduced to save the budget cost and make a choice according to the cost performance when the project is implemented.

[0057] The rest of this embodiment is the same as that of Embodiment 1, so it will not be elaborated here.

[0058] Embodiment 3:

[0059] This embodiment is further implemented on the basis of Embodiment 2. As Figure 2 shown, the handling clip includes a body made of magnetic material, and a wheel body is rotatably connected to the bottom of the body; the linear track buried under the top plate of the operation platform 04 has a moving part, and a magnet is installed on the moving part.

[0060] The handling clip in this embodiment has a body made of magnetic material and is attracted by the magnet on the moving part located below to be restricted on the upper surface of the operation platform 04; as the moving part with its own power source moves along the linear track, it drives the handling clip to move together. In order to make the movement of the handling clip smoother, a wheel is rotatably connected below the body to reduce the static friction. By adjusting and setting the movement parameters of the moving part through the industrial computer, the trajectory of the handling clip is controlled to complete the position movement of the glass plate 053 on the upper surface of the operation platform 04. After the glass plate 053 is used up, through the glass cleaning mechanism arranged on one side of the operation platform 04, the glass plate 053 is pushed out of the operation platform 04 to prepare for cleaning and drying and then used again. A truncated cone cleaning mechanism is also arranged on the side of the operation platform 04 for cleaning the truncated cone, the stirring funnel and the stirring blades.

[0061] The rest of this embodiment is the same as that of Embodiment 2, so it will not be elaborated here.

[0062] Embodiment 4:

[0063] This embodiment is further implemented on the basis of Embodiment 3. As Figure 1As shown, a plurality of card seats for placing the stirring funnel and / or the stirring blades are provided on the placing rack 01, and a weight sensor is provided in each of the card seats. The weight sensor is connected to the manipulator 09.

[0064] The weight difference between the stirring funnel and the stirring blades is relatively large. The weight sensor can easily sense different mass signals and output corresponding electrical signals to the manipulator 09. The manipulator 09 can determine whether the card seat where the weight sensor is located is empty, or has a stirring funnel or a stirring blade placed in it based on the obtained electrical signals, and the manipulator 09 performs corresponding grasping actions accordingly, effectively avoiding the manipulator 09 grasping in vain or grasping wrongly due to incorrect manual placement.

[0065] The remaining parts of this embodiment are the same as those of Embodiment 3, so they will not be described again.

[0066] Embodiment 5:

[0067] This embodiment is further implemented on the basis of Embodiment 4. The batching machine 02 includes a batching controller, an admixture peristaltic pump, a water peristaltic pump, and a powder filling machine. The industrial computer is connected to the batching controller, and the batching controller is respectively connected to the admixture peristaltic pump, the water peristaltic pump, and the powder filling machine.

[0068] Under the clamping of the manipulator 09, the stirring funnel comes to the lower part of the discharge ports of the admixture peristaltic pump, the water peristaltic pump, and the powder filling machine. The controller of the batching machine 02 controls the discharge of the admixture peristaltic pump, the water peristaltic pump, and the powder filling machine to fill the stirring funnel according to the set parameters, completing the quantitative proportioning process of the cement paste.

[0069] Furthermore, a plurality of powder boxes with different capacity specifications are provided in the powder filling machine. When batch detection is required, let the worker pre-fill the powder boxes with the pre-mixed dry powder components to be tested. When in use, the filled powder boxes are sequentially placed into the powder filling machine according to the test sequence and are sequentially filled into the stirring funnel, and then the quantitative proportioning of the cement paste components can be completed.

[0070] The remaining parts of this embodiment are the same as those of Embodiment 4, so they will not be described again.

[0071] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modifications and equivalent changes made to the above embodiments based on the technical essence of the present invention all fall within the protection scope of the present invention.
