Referring to fig. 1 to 4, a detection module 1 according to a first embodiment of the present invention is used for detecting an arc-shaped circuit board P, and the detection module 1 includes:

a base 10 having a top 11 and a bottom 12, the base 10 having a receiving slot 13 formed on the top 11 and recessed toward the bottom 12. In the embodiment, the accommodating groove 13 is long, but not limited thereto. The vessel 13 has a bottom 14 and a wall 15 surrounding the bottom. Two limiting portions 16 are formed by recessing from the opposite ends of the wall surface 15 of the base 10 toward the body. It should be noted that the two limiting portions 16 can also be disposed on the top portion 11 of the base 10 and protrude from the opposite ends of the top portion 11 toward the accommodating groove 13, so that the same technical effects can be achieved immediately after simple replacement by those skilled in the art after referring to fig. 1 and the specification of the present application, and further description thereof is omitted.

A floating seat 20, which is arranged in the containing groove 13 of the base 10. At least two elastic members 21 are disposed between the floating seat 20 and the wall surface 15 of the accommodating groove 13, but not limited thereto. In the present embodiment, the two elastic members 21 are disposed between the opposite wall surfaces 15 and the floating seat 20. Three or four or more elastic members 21 may be disposed between the wall surface 15 and the floating seat 20, and the elastic members 21 may be springs, elastic pieces, rubber or foamed materials, etc. with elasticity, so that a variable gap may be maintained between the floating seat 20 and the wall surface 15. The floating seat 20 may be formed by combining an upper seat 22 and a lower seat 23, but the upper seat 22 and the lower seat 23 may also be integrally formed. In the present embodiment, the floating seat 20 is assembled to the bottom surface 14 of the receiving groove 13 of the base 10 through the lower seat 23, and the floating seat 20 is also long corresponding to the receiving groove 13 of the base 10, if the distance between the upper seat 22 and the lower seat 23 of the floating seat 20 is different at two ends in the long axial direction when viewed from the long axial direction, and because the two ends of the lower seat 23 of the floating seat 20 in the long axial direction are not equal in height, when the upper seat 22 of the floating seat 20 is combined to the top surface of the lower seat 23, the floating seat 20 can be expected to be inclined from one end to one direction integrally, so as to match the shape of the arc-shaped circuit board P.

At least one set of insertion holes 24, a detection circuit board 25 and an electrical connector 28 for connecting to an external electrical device are disposed above the upper seat 22 of the floating seat 20. A plurality of probes 241 are disposed in the at least one set of insertion holes 24, and the plurality of probes 241 are respectively electrically connected to one end of the detection circuit board 25 after passing through a socket 243, and the other end of the detection circuit board 25 protrudes toward the direction away from the upper seat 22 of the floating seat 20 and is electrically connected to the electrical connector 28. It should be noted that, in the present embodiment, the upper seat 22 of the floating seat 20 is provided with two groups of insertion holes 24, the detection circuit board 25 is formed by a PCB, and the electrical connector 28 is disposed at the protruding end of the upper seat 22 of the floating seat 20 and electrically connected to the other end of the detection circuit board 25.

Two ends of the lower base 23 of the floating base 20 are respectively protruded with a protruding wall portion 26, so that when the floating base 20 is disposed in the container 13, the two protruding wall portions 26 are respectively and correspondingly limited between the two limiting portions 16 of the base 10 and the bottom surface 14 of the container 13, so as to prevent the floating base 20 from being separated from the container 13 during operation.

A fixing base 30 having a plurality of through holes 31 for bolts to pass through.

A guide rail 40 disposed at one side of the fixing base 30, and the base 10 straddles the guide rail 40 and can move along the long axis direction of the guide rail 40. It should be noted that the recessed direction of the two position-limiting portions 16 of the base 10 is the same as the forming direction of the guide rail 40.

Two elastic pulling members 50 respectively disposed at two sides of the base 10, wherein one end of each of the two elastic pulling members 50 is connected to the fixing base 30, and the other end thereof is connected to the base 10. In the present embodiment, the two elastic pulling members 50 are two extension springs, but not limited thereto, only one elastic pulling member 50 may be used, or an elastic rubber or other elements with the same stretching function may also be used. The two elastic pulling members 50 can generate a pulling force when the base 10 is displaced, so that the base 10 can return to its original position.

Fig. 4 to fig. 6 are schematic views illustrating the base 10 straddling the guide rail 40 and moving along the long axis direction of the guide rail 40. Because the floating seat 20 and the base 10 are connected by the elastic members 21, the floating seat 20 can keep a sliding margin with respect to the base 10. Therefore, when the inserting holes 24 on the upper seat 22 of the floating seat 20 are to be matched and connected to the connecting port of the external electrical device and need to be adjusted and displaced, as shown in fig. 5, the base 10 can be moved to a predetermined position along the long axis direction of the guide rail 40, so that the inserting holes 24 on the upper seat 22 of the floating seat 20 can be moved to the position below the corresponding connecting port, and then the floating seat 20 can slightly rotate counterclockwise or clockwise relative to the base 10, as shown in fig. 6, in this embodiment, the floating seat 20 is slightly rotated and displaced counterclockwise, so that the two elastic members 21 at the opposite ends of the wall surface 15 of the base 10 are compressed; finally, the plug holes 24 on the upper seat 22 of the floating seat 20 and the connection ports of the external matching electrical devices can be smoothly connected.

As shown in fig. 7 and 8, in order to provide a detecting device 2 according to the present invention, the detecting device 2 includes:

In this embodiment, the bottom plate 60 is provided with four detection modules 1, which are divided into two groups, each group including two detection modules 1, and when any one of the detection modules 1 is installed, the lower end of the upper seat 22 of the floating seat 20 faces the middle of the bottom plate 60, so as to match the shape of the arc-shaped circuit board P that is higher in periphery and lower in middle when straddling on the bottom plate 60. The number and the positions of the detecting modules 1 can be changed according to the requirement of the P-curve of the arc-shaped circuit board to be detected, and the number is not limited to the number disclosed in the embodiment.
