Description

Two-stage stroke detection device and detection platform using the detection device

The present invention is related to electronic product testing technology, and particularly refers to a detection device with two-stage stroke actions such as horizontal movement and vertical depression, and a detection platform using the detection device.

Due to the wide variety of electronic product testing modules currently used, and in order to further ensure that the product can operate normally and completely after the manufacturing is completed, a certain procedural electrical test is required before the electronic product is shipped. , So I designed a detection module that meets specific electronic products, as disclosed in the Republic of China New Patent Announcement No. TWM527961U No. B (the following signs are quoted in the examples of the aforementioned patents). Sectional electronic product testing probe fixture module", which includes a two-section probe fixture module 1, a two-section probe fixture 10, a testing machine 2, an electronic product 3, and a probe Needle holder 4. The testing machine 2 is a flat plate for accommodating the test electronic product 3, and the two-section probe fixture 10 is pivotally connected to the testing machine 2.

When testing, the electronic product 3 is first inserted into the panel groove 21 of the testing machine 2. At this time, the rocker 13 is pivotally connected to a rocker support base 15 and is located at a starting position; Then, when the rocker 13 is pressed down to a predetermined angle (about 45 degrees), a connecting rod 16 connected to the shaft and a horizontal sliding block 17 connected to the shaft can be driven to move horizontally, and it is worth mentioning that , The horizontal sliding block 17 is screwed to a fixture cover 12 by a plurality of lateral linear sliding rails 121 and a straight down linear sliding rail 111 is screwed to a fixture base 11 to produce smooth movement; then, when When the axle-connected roller 19 moves and rotates at the same time, it can drive an inclined bottom plate 142 to move vertically downward, and it is worth mentioning that the inclined bottom plate 142 is fixed to the probe Since the plurality of guide posts 141 move vertically at the same time, the holder-locking base 14 enables the probes in the probe holder 4 to be electrically connected to the electronic product 3 to be tested for electrical testing.

Although, the two-stage electronic product inspection probe jig module disclosed in the above-mentioned Republic of China Patent Publication No. TWM527961U can make the overall inspection stroke roughly divided into two stages, such as a horizontal movement and a vertical depression. Detect stroke movement. However, it is also because the two-stage actuation relationship of horizontal movement and vertical depression is generated only by the linkage relationship between the components in the overall mechanism. Therefore, if you want to return to the initial position to be measured, you must Then force is applied to the fixture upper cover 12, the rocker 13 or the probe holder lock base 14 and other components until a resistance force sufficient for the fixture module to return to the initial position is generated.

If things go on like this, in addition to making the entire inspection process time-consuming and laborious, it is also prone to wear and tear on the inspection fixture module due to improper force. For this reason, as to how to make the inspection fixture module and its combined components overcome the aforementioned technical defects, there is actually room for immediate improvement.

In view of the foregoing, the present invention provides a detection device with two-stage stroke actions such as horizontal movement and vertical depression.

Please refer to FIG. 1, FIG. 5, FIG. 10, and FIG. 11 together. When the detection device 2 is applied to the detection platform 1 disclosed in the first embodiment of the present invention and the detection stroke is performed, first, first The detection device 2 is assembled on the detection board 3 through the base 10 , and then a pin header group 4 (a plurality of metal probes is exemplified in this embodiment) is assembled on the probe of the detection device 2 The other end of the seat 30 , and the pin set 4 is close to the position of the detection area 5. At this time, the pressing rod 21 of the actuation unit 20 of the detection device 2 is caused by the magnetic fastener 22 and the base The magnetic fasteners 18 of the upper cover 17 of the seat 10 are magnetically attracted to each other to be fastened and fixed.

Deck, Please Referring to FIG. 2 and FIG. 12, therefore, when the user presses the lever by means of the detection of 21 2, so that the lever member 21 of the magnetic clasp 22 and the base 10 of the magnetic fasteners 18 The phenomenon of magnetic buckle between the two is eliminated, and the angle between the pressing rod 21 and the upper cover 17 of the base 10 is greater than a first predetermined angle θ1 (in this embodiment, for example, it is greater than 45 degrees. , And its preferred implementation angle is between 15 degrees and 60 degrees), because the two ends of the connecting rod 23 are pivotally connected to the pressing rod 21 and the sliding block 25 , the connecting rod 23 the drive system presents a horizontal traversing movement of the slider 25 in the direction of the inclined surface 30 of the probe holder base 31, while also indirectly, such that the support arm 24 to drive the probe toward a direction away from the seat 30 and the base 10 toward the The direction of the detection zone 5 of the detection platform 1 moves horizontally, and the two springs 29 respectively arranged between the support arm 24 and the two stop portions 16 of the base 10 are gradually formed in a compressed state Therefore, the support arm 24 no longer exhibits horizontal lateral movement, and indirectly, the probe holder 30 no longer exhibits a limited horizontal lateral movement.

Continuing, please refer to FIGS. 9, 13 and 14 together. Then, when the user continuously presses the pressure rod 21 of the detection device 2 , the pressure rod 21 and the upper cover 17 of the base 10 are both The included angle is gradually changed from the first predetermined angle θ1 to greater than a second predetermined angle θ2 (in this embodiment, for example, it is greater than 75 degrees, and the preferred implementation angle is between 60 degrees and 90 degrees. ) causes the slider stopper 25 of the stopper rod 250 is elongated to the interference limiting hole of the support arm 24 of the other side of the position 240, the support arm 24 and a base 10 with the The relationship between the two linear slide rails 28 between the inner wall surfaces of the peripheral wall 12 to limit the sliding movement, so that the slider 25 can continue to face the inclined base 31 of the probe holder 30 relative to the support arm 24 At this time, because the roller 27 pivoted on the slider 25 gradually rolls from the lower end of the inclined surface base 31 of the probe holder 30 toward the high end direction, the probe The seat 30 moves vertically downward toward the connection port of the test object 7 in the detection area 5 as a whole, and causes the two springs 33 arranged between the probe seat 30 and the support arm 24 of the actuation unit 20 The compressed state is gradually formed until an electrical connection is formed between the pin set 4 installed in the probe holder 30 and the connection port of the test object 7 in the detection zone 5 , that is, The plurality of metal probes in the pin header group 4 of the probe holder 30 perform electrical detection on the test object 7 in the detection area 5 .
