And, where feasible, features of different embodiments can be interchanged.

[0055] Unless otherwise defined, all terms used herein (including technical and scientific terms) have their ordinary meanings, meanings that are understandable to those skilled in the art. Furthermore, the definitions of the aforementioned terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.

[0056] Please refer to Figures 1-2 . Figure 1 This is a front view of an electrical measuring device 100 according to an embodiment of the present invention. Figure 2 To illustrate along Figure 1 A cross-sectional view of line segment AA. In this embodiment, as... Figures 1-2As shown, an electrical testing apparatus 100 includes a table 110, a pair of conveying rails 120, and a first moving device 130. The table 110 has a supporting surface 110S configured to support a jig assembly 200. The conveying rails 120 are configured to convey a test object 300 (see Figure 5 ), and the conveying rails 120 are spaced apart from the supporting surface 110S by a distance X. The first moving device 130 is disposed on the table 110 and connected to the conveying rails 120, and the first moving device 130 is configured to move the conveying rails 120 relative to the table 110 to change the distance X. In practice, the first moving device 130 is configured to move the conveying rails 120 vertically relative to the supporting surface 110S.

[0057] Specifically, the jig assembly 200 has a height H. In the present embodiment, the maximum value of the distance X between the conveying rails 120 and the supporting surface 110S is greater than the height H of the jig assembly 200. In other words, when the conveying rails 120 are moved relative to the table 110 to reach the maximum value of the distance X between the conveying rails 120 and the supporting surface 110S, the jig assembly 200 can pass between the conveying rails 120 and the supporting surface 110S, as shown. Figure 1

[0058] Further, as shown, Figure 1 the jig assembly 200 includes an upper jig 210 and a lower jig 220, the upper jig 210 is foldably connected to the lower jig 220, the lower jig 220 is located between the upper jig 210 and the supporting surface 110S, and the upper jig 210 and the lower jig 220 are configured to sandwich the test object 300 therebetween. That is, when the conveying rails 120 are moved relative to the table 110 to reach the maximum value of the distance X between the conveying rails 120 and the supporting surface 110S, the upper jig 210 and the lower jig 220 can pass between the conveying rails 120 and the supporting surface 110S in a combined state by means of a cart (not shown) and be placed on the supporting surface 110S of the table 110. This not only improves the efficiency of placing the jig assembly 200 on the electrical testing apparatus 100, but also avoids the chance of misplacing the lower jig 220 and the upper jig 210 when the lower jig 220 is placed first and then the upper jig 210 is placed.

[0059] Further, as shown, Figure 1 the first moving device 130 includes two sub-moving devices 131, each of the sub-moving devices 131 is connected to opposite ends of each of the conveying rails 120, and the sub-moving devices 131 are configured to move the conveying rails 120 vertically relative to the table 110 to change the distance X. Figure 2 One of the two sub-moving devices 131 is shown.

[0060] Further, as shown, Figures 1-2 ​As shown, each of the sub-moving devices 131 includes a support portion 132, a drive portion 133, and a moving rod 134. A conveyor rail 120 is disposed on the support portion 132. The drive portion 133 is connected to the machine base 110. The moving rod 134 is connected between the drive portion 133 and the support portion 132. The drive portion 133 is configured to move the moving rod 134 so that the support portion 132 moves closer to or further away from the support surface 110S of the machine base 110; that is, the support portion 132 is configured to move relative to the drive portion 133. In this embodiment, the combination of the drive portion 133 and the moving rod 134 can be a hydraulic cylinder or a pneumatic cylinder. In other embodiments, the moving rod 134 can be a threaded rod, and the drive portion 133 is configured to rotate the moving rod 134 so that the moving rod 134 moves relative to the drive portion 133.

[0061] To make the movement of the supporting part 132 relative to the driving part 133 more stable, in this embodiment, such as Figure 2 As shown, each of the sub-moving devices 131 further includes a fixing part 135 and a guide rod 136. The fixing part 135 is connected to the machine base 110. The guide rod 136 is connected to the support part 132 and slidably connected to the fixing part 135, and the guide rod 136 is parallel to the moving rod 134. Preferably, as Figure 2 As shown, each of the sub-moving devices 131 has four guide rods 136, but this invention is not limited to this. For the sake of brevity, the fixing part 135 and the guide rods 136 are not shown in other figures.

[0062] Please refer to Figure 3 . Figure 3 To illustrate along Figure 1 A cross-sectional view of line segment BB. In this embodiment, as... Figure 1 , 3 As shown, the machine tool 110 has at least one through hole P (see Figure 110 for details). Figure 1 The through hole P is located on the support surface 110S. The electrical testing equipment 100 also includes at least one roller assembly 160 and a third moving device 170. The roller assembly 160 includes a base 161 and a plurality of rollers 162, each of which is rotatably connected to the base 161. The third moving device 170 is disposed on the machine base 110 and connected to the base 161 of the roller assembly 160, and the third moving device 170 is configured to move the base 161 relative to the machine base 110 so that the rollers 162 protrude from the support surface 110S of the machine base 110 at least partially through the through hole P.

[0063] Furthermore, such as Figure 1 , 3As shown, when placing the jig assembly 200 into the electrical testing apparatus 100, the jig assembly 200 is first supported by the rollers 162 protruding from the support surface 110S, and the jig assembly 200 does not contact the support surface 110S of the machine 110. In this case, even if the jig assembly 200 including the upper jig 210 and the lower jig 220 has a large weight, by rotating the rollers 162, the user can easily push the jig assembly 200 to the appropriate position inside the electrical testing apparatus 100.

[0064] Please refer to Figure 4 . Figure 4 for illustrating Figure 1 a front view of the electrical testing apparatus 100, in which the support surface 110S supports the jig assembly 200. In the present embodiment, as shown, when the jig assembly 200 has been located at the appropriate position inside the electrical testing apparatus 100, the third moving device 170 moves the base 161 relative to the machine 110, so that the rollers 162 are retracted into the support surface 110S of the machine 110, and the jig assembly 200 contacts and is supported by the support surface 110S. Figure 4

[0065] Further, as shown in Figure 1 , 4 , the electrical testing apparatus 100 further includes a clamping device 140 and a second moving device 150. The clamping device 140 is configured to clamp the upper jig 210 of the jig assembly 200. The second moving device 150 is connected to the machine 110 and the clamping device 140, and is configured to move the clamping device 140 relative to the machine 110, so that the clamping device 140 approaches or moves away from the lower jig 220.

[0066] Furthermore, as shown in Figure 1 , 4 , the upper jig 210 includes a jig body 211 and a plurality of first clamping portions 212, and the first clamping portions 212 are arranged on the jig body 211. Specifically, in the state that the upper jig 210 is combined with the lower jig 220, the highest point of the first clamping portions 212 and the lowest point of the lower jig 220 define the height H described above. Correspondingly, the clamping device 140 includes a device body 141 and a plurality of second clamping portions 142, and the second clamping portions 142 are movably connected to the device body 141 and are configured to clamp the first clamping portions 212 of the upper jig 210. As shown in Figure 1 , the clamping device 140 does not move towards the upper jig 210. As shown in Figure 4 , the clamping device 140 has moved towards the upper jig 210, and the second clamping portions 142 have moved relative to the device body 141 and clamped the first clamping portions 212 of the upper jig 210.

[0067] Please refer to Figure 5 . Figure 5 ​To illustrate Figure 4 a front view of the electrical testing apparatus 100, wherein the upper fixture 210 is distanced from the lower fixture 220, and the conveying track 120 is at least partially located between the upper fixture 210 and the lower fixture 220. In this embodiment, as shown in Figure 5 the second moving device 150 moves the clamping device 140 together with the upper fixture 210 away from the lower fixture 220. At this time, the first moving device 130 moves the conveying track 120 relative to the machine table 110, so that the conveying track 120 is at least partially located between the upper fixture 210 and the lower fixture 220, and the object 300 conveyed on the conveying track 120 from the previous work station can be transferred from the conveying track 120 to the lower fixture 220 by the operating mechanism (not shown) of the lower fixture 220, so as to facilitate the upper fixture 210 and the lower fixture 220 to clamp the object 300 therebetween and perform subsequent electronic testing.

[0068] In summary, the technical solutions disclosed in the above embodiments of the present application have at least the following advantages:

[0069] (1) When the conveying track is moved relative to the machine table and the distance between the conveying track and the supporting surface reaches the maximum value, the upper fixture and the lower fixture can pass through the space between the conveying track and the supporting surface in a combined state by using the trolley, and are placed on the supporting surface of the machine table. This not only improves the efficiency of placing the fixture combination on the electrical testing apparatus, but also avoids the possibility of misplacing the two fixtures when the lower fixture is placed first and then the upper fixture is placed.

[0070] (2) When the fixture combination is placed on the electrical testing apparatus, the fixture combination is first supported by the rollers protruding from the supporting surface, and the fixture combination does not contact the supporting surface of the machine table. In this case, even if the fixture combination including the upper fixture and the lower fixture has a relatively large weight, the user can easily push the fixture combination to the appropriate position in the electrical testing apparatus by rotating the rollers.

[0071] Although the present application has been disclosed in the above embodiments, it is not intended to limit the present application, and any person skilled in the art can make various modifications and decorations without departing from the spirit and scope of the present application, therefore the protection scope of the present application shall be subject to the appended claims.
