[0002] Ultrasonic testing is a non-destructive testing method used in the ceramic industry.

[0026] It can be understood that, in one implementation, the first ultrasonic probe 120 is an ultrasonic generator, and the second ultrasonic probe 220 is an ultrasonic receiver. In another implementation, the first ultrasonic probe 120 is an ultrasonic receiver, and the second ultrasonic probe 220 is an ultrasonic generator. During detection, the upper translation module 100 is located on the upper surface of the ceramic plate to be tested, and the lower translation module 200 is located on the lower surface of the ceramic plate to be tested. The sliders of the upper translation module 100 and the lower translation module 200 are provided with ultrasonic generators and ultrasonic receivers arranged oppositely in the vertical direction. The present invention drives the first ultrasonic probe 120 to move by the first driving component 110, and drives the second ultrasonic probe 220 to move by the second driving component 210, so as to realize automatic ultrasonic detection of the ceramic plate, thereby improving the accuracy and efficiency of the detection.

[0027] In one implementation, see Figure 2 and Figure 3 The upper translation module 100 further includes: a first cylinder mounting plate 130 and a first cylinder 140. The first cylinder mounting plate 130 is disposed on the first driving assembly 110, and the first cylinder 140 is disposed on the first cylinder mounting plate 130. The tail end of the movable rod of the first cylinder 140 is disposed downward, and the first ultrasonic probe 120 is disposed vertically downward on the tail end of the movable rod of the first cylinder 140. The first cylinder mounting plate 130 can drive the first ultrasonic probe 120 up and down, and the ceramic plate to be tested is pressed before the test.

[0028] Further, the lower end surface of the tail end of the movable rod of the first cylinder 140 is provided with a first probe adjustment plate 150, and the lower end surface of the first probe adjustment plate 150 is provided with a first probe fixing seat 160, one end of the first probe fixing seat 160 is a concave first semicircular end surface, and the first semicircular end surface is adapted to be equipped with a first probe clamp 170, and the first probe clamp 170 is used to install the first ultrasonic probe 120 on the first semicircular end surface. The advantage of providing the first probe clamp 170 is that the installation position of the first ultrasonic probe 120 can be adjusted up and down.

[0029] Furthermore, the first driving component 110 includes: a dual-axis motor 111, a first coupling 112 and a first module 113 which are arranged in sequence, a first output shaft is arranged on one side of the dual-axis motor 111, the first output shaft is connected to the input shaft of the first module 113 through the first coupling 112, a first slider which can move along the input shaft of the first module 113 is arranged on the first module 113, the first cylinder mounting plate 130 is arranged on the first slider, and the first slider is used to drive the first cylinder mounting plate 130 on the first slider to translate under the drive of the dual-axis motor 111.

[0030] In one implementation, see Figure 4 and Figure 5 The lower translation module 200 further includes: a second cylinder mounting plate 230 disposed on the second driving assembly 210, and a second cylinder 240 disposed on the second cylinder mounting plate 230; the tail end of the movable rod of the second cylinder 240 is disposed upward, and the second ultrasonic probe 220 is disposed vertically upward on the tail end of the movable rod of the second cylinder 240. In this way, when the movable rods of the first cylinder 140 and the second cylinder 240 are extended, the movable rods of the two cylinders are relatively close, and the first ultrasonic probe 120 and the second ultrasonic probe 220 are pressed against the front and back sides of the ceramic plate to be tested; after the test is completed, the cylinder movable rods are retracted, and the first ultrasonic probe 120 and the second ultrasonic probe 220 are separated from the ceramic plate to be tested.

[0031] Further, the upper end surface of the rear end of the movable rod of the second cylinder 240 is provided with a second probe adjustment plate 250, the upper end surface of the second probe adjustment plate 250 is provided with a second probe fixing seat 260, one end of the second probe fixing seat 260 is a concave second semicircular end surface, the second semicircular end surface is adapted with a second probe clamp 270, and the second probe clamp 270 is used to install the second ultrasonic probe 220 on the second semicircular end surface. The advantage of providing the second probe clamp 270 is that the installation position of the second ultrasonic probe 220 can be adjusted up and down.

[0032] Furthermore, a second output shaft is provided on the other side of the dual-axis motor 111, and a first synchronous wheel 180 is provided on the second output shaft; the second driving assembly 210 includes: a second synchronous wheel 211, a transmission shaft 213, a second coupling 214 and a second module 215 which are arranged in sequence, the second synchronous wheel 211 is connected to the first synchronous wheel 180 through a belt 300, bearings 212 are provided at both ends of the transmission shaft 213, and a bearing support plate 216 is sleeved on the bearing 212; a second slider which can be moved along the input shaft of the second module 215 is provided on the second module 215, and the second cylinder mounting plate 230 is arranged on the second slider, and the second slider is used to drive the second cylinder mounting plate 230 on the second slider to translate under the drive of the second driving wheel.

[0033] In this way, it is only necessary to install a motor in one of the modules, and realize synchronous control through synchronous belt linkage, so that the relative positions of the ultrasonic generators and ultrasonic receivers of the two modules are kept consistent. In addition, the slider movements of the upper translation module 100 and the lower translation module 200 can also be controlled separately, and the sliders are kept relatively fixed in position through motor control. For example, the upper translation module 100 and the lower translation module 200 are both set to the structure of the upper translation module 100 without the use of synchronous wheels; that is, the dual-axis motor 111 is also installed on the lower translation module 200. Alternatively, the upper translation module 100 and the lower translation module 200 are exchanged for use, that is, the upper translation module 100 is placed at the bottom and the lower translation module 200 is placed at the top for use.

In addition, a connecting plate may be disposed between the upper mounting plate assembly 400 and the lower mounting plate assembly 500 to enhance the stability of the dual-module device.

[0035] Furthermore, the upper translation module 100 and the lower translation module 200 can be installed in a fixed manner on the ceramic plate conveyor line frame, and the multi-position detection of the conveying direction of the ceramic plate is realized by the conveying function of the conveyor line. The detection method is: the ceramic plate enters the middle of the upper translation module 100 and the lower translation module 200 along the conveyor line. When it reaches the first row of predetermined detection positions, the conveyor line stops, and the upper translation module 100 and the lower translation module 200 drive the slider to translate, so that the ultrasonic generator and the ultrasonic receiver reach the preset detection points in turn, and the cylinders move one by one to detect step by step; after the first row of detection points are detected, the ceramic plate continues to be conveyed, and the conveyor line stops when the next row of detection positions reaches between the upper translation module 100 and the lower translation module 200, and the above detection action is repeated; the above-mentioned conveyor line stop-translation detection-conveyor line operation action is repeated multiple times until all preset point detections are completed and the detection and collection are completed.

[0036] Furthermore, the upper translation module 100 and the lower translation module 200 have another installation method: auxiliary brackets parallel to the conveying direction are respectively arranged at the upper and lower parts of one side of the conveying line, and the auxiliary brackets are provided with slide rails and sliders. The upper translation module 100 and the lower translation module 200 are respectively fixed on the sliders through the upper mounting plate assembly 400 and the lower mounting plate assembly 500; the upper mounting plate assembly 400 and the lower mounting plate assembly 500 are connected through a driving plate; a driving device is provided on the conveying line, and when the driving device pushes the driving plate During translation, the upper translation module 100 and the lower translation module 200 translate as a whole along the conveying direction of the conveyor line; under this installation method, the conveyor line stops when the ceramic plate to be tested enters the predetermined detection position, and when the driving device pushes the driving plate to translate, the upper translation module 100 and the lower translation module 200 reach the detection position in turn, and the upper translation module 100 and the lower translation module 200 move in turn to make the ultrasonic generator and the ultrasonic receiver reach the detection point for detection; after all detection points are detected, the conveyor line continues to move to output the ceramic plate to be tested.

[0037] Furthermore, the upper translation module 100 and the lower translation module 200 are fixed on the slide rail slider of the auxiliary bracket on one side of the conveyor line through the upper mounting plate assembly 400 and the lower mounting plate assembly 500, which is a cantilever form; the other installation is a gantry form, and the upper and lower parts of both sides of the conveyor line are provided with auxiliary brackets, and the auxiliary brackets are provided with slide rail sliders, the upper mounting plate assembly 400 is composed of an upper left mounting plate assembly and an upper right mounting plate assembly, and the lower mounting plate assembly 500 is composed of a lower left mounting plate assembly and a lower right mounting plate assembly, the upper translation module 100 is fixed on the upper left mounting plate assembly and the upper right mounting plate assembly, and the lower translation module 200 is fixed on the lower left mounting plate assembly and the lower right mounting plate assembly.

[0038] In one implementation, a first guide is disposed on the lower end surface of the first probe adjustment plate 150, and a first long waist hole perpendicular to the translation direction of the first driving assembly 110 is disposed on the first probe fixing seat 160. In this way, the first probe adjustment seat can be used to adjust the relative position of the center of the first ultrasonic probe 120 so that it is aligned with the center of the second ultrasonic probe 220.

[0039] Furthermore, a second guide is provided on the upper end surface of the second probe adjustment plate 250, and a second long waist hole perpendicular to the translation direction of the second driving assembly 210 is provided on the second probe fixing seat 260. In this way, the second probe adjustment seat can be used to adjust the relative position of the center of the second ultrasonic probe 220 so that it is aligned with the center of the first ultrasonic probe 120.

[0040] In summary, the present invention discloses a dual-module device for ultrasonic detection, comprising: an upper translation module and a lower translation module, wherein the upper translation module is located above the lower translation module; the upper translation module comprises: a first drive assembly, and a first ultrasonic probe connected to the first drive assembly; the lower translation module comprises: a second drive assembly, and a second ultrasonic probe connected to the second drive assembly; the first drive assembly is used to drive the first ultrasonic probe to move to a test point; when the first ultrasonic probe and the second ultrasonic probe both reach the test point and are in an aligned state, the first ultrasonic probe and the second ultrasonic probe perform ultrasonic detection on the ceramic plate to be tested located between the upper translation module and the lower translation module.
