Description

Testing device with batch testing and testing platform using the testing device

The present invention is related to electronic product testing technology, and particularly refers to a testing device with batch testing and a testing platform using the testing device.

There are many types of electronic product testing modules currently in use. In order to further ensure the normal and complete operation of the product after the manufacturing is completed, it is necessary to pass a certain procedural electrical test before the electronic product is shipped. Then design a detection module that meets the specific electronic product. That is, as disclosed in the Republic of China Invention Patent Announcement No. TWI712799 No. B (the following reference numbers refer to the reference numbers listed in the embodiments of the aforementioned patent cases) "Two-stage stroke detection device and detection platform using the detection device" As shown in the figures, a detection platform 1 is provided with a detection device 2 and a detection board 3, and the detection device 2 includes a base 10, an actuation unit 20 and a probe holder 30, and the detection The base 10 of the device 2 is assembled on the detection board 3 of the detection platform 1. When a pressing rod 22 of the actuating unit 20 of the detection device 2 is pressed so that the angle between the pressing rod 22 and the base 10 is greater than a first predetermined angle θ1, the actuating unit 20 has A connecting rod 23 of the actuating unit 20 drives a slider 25 of the actuating unit 20 to move horizontally toward the inclined base 31 of the probe base 30, and at the same time, the support arm 24 of the actuating unit 20 drives the probe The needle holder 30 moves horizontally and transversely in the direction away from the base 10 and toward the detection area 3 of the detection platform 1, and also allows it to be separately arranged at the two stops of the support arm 24 and the base 10 The two springs 29 between the portions 16 gradually form a compressed state, so that the support arm 24 no longer moves horizontally, and indirectly prevents the probe holder 30 from moving horizontally. Then, when the pressure rod 22 of the detection device 2 is continuously pressed, the angle between the pressure rod 22 and the base 10 gradually changes from the first predetermined angle θ1 to greater than a second predetermined angle θ2 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 base 30 toward the high end, so that the probe base 30 as a whole faces the detection platform The detection zone 5 of the detection board 3 of 1 moves downward, and the two springs 33 arranged between the probe holder 30 and the support arm 24 of the actuation unit 20 gradually form a compressed state until they are installed.

The above are the technical features of the detection device 100 and its components of the detection platform 1 disclosed in the first preferred embodiment of the present invention. When the detection device 100 is applied to the detection platform 1 and a detection stroke is performed, Please refer to FIGS. 1 to 8 together. First, the detection device 100 is assembled on the detection board 2 through the base 10 so that the four detection devices 40 of the detection device 100 One end of the needle base 47 equipped with a plurality of metal probes is respectively close to the positions of the four detection areas 3 of the detection plate 2. At this time, since the two ends of the pressure plate 30 are respectively connected to the two of the two actuating units 20 The relationship between the pressure rod 22, so when the operator presses the pressure plate 30, the two pressure rods 22 are pivoted together, and the two pressure rods 22 gradually move toward the two fixed seats 21 The directions of the two baffles 27 are close, and because the two ends of the link 23 of any actuating unit 20 are pivotally connected to the pressing rod 22 and the supporting arm 25, and the two supporting arms 25 are movably different Straddling the guide rail 24 and sliding along the long axis of the guide rail 24 and other factors, the connecting rod 23 drives the support arm 25 toward the two inclined surfaces of the actuating plate 41 of the detection assembly 40 The direction of the section 416 presents a horizontal movement.

Preferably, when the pressure rod 22, the connecting rod 23 and the support arm 25 of any one of the actuating units 20 form a pivot balance point (also called a dead point or a reflex point), This makes the electrical detection process between the probe holders 47 of the detection assembly 40 of the detection device 100 and the test objects on the detection areas 3 of the detection platform 1 more stable. More preferably, when the pressing rods 22 of the two actuating units 20 protrude from one side of the fixing seat 21, the magnetic fasteners 221 embedded in the magnetic fasteners 221 respectively correspond to the magnetic fasteners embedded in the short sides of the baffle 27 At the position of 271, due to the magnetic attraction effect, the two pressing rods 22 of the two actuating units 20 and the second baffle plate 27 form a magnetic buckle and are fixed, thereby preventing the pressing plate 30 from being electrically detected. The rebound phenomenon occurred during the process, which led to the failure of the electrical test.

Please refer to FIGS. 1 to 12 together. When the pressing plate 30 of the detection device 100 is pulled until the magnetic fasteners 221 of the two pressing rods 22 of the two actuating units 20 and the two baffle plates 27 The magnetic attraction effect between the two magnetic fasteners 271 is eliminated; then, the pressure plate 30 is continued to be pulled to allow the two components arranged between the actuating plate 41 and the connecting plate 43 of the detection assembly 40 When the spring 46 again overcomes the previously formed pivotal balance point between the two pressure rods 22, the connecting rod 23 and the support arm 25 of the two actuating units 20, the self-compression state gradually returns to the original State, at this time, the roller 26 pivoted on the two supporting arms 25 of the two actuating units 20 is driven from the high end of the two inclined plane sections 416 of the actuating plate 41 of the detection assembly 40 toward lower Therefore, the connecting plate 43 of the detection assembly 40 starts to show a vertical upward return movement in the opposite direction away from the connection ports of the detection areas 3, so that the detection of the connecting plate 43 The plurality of metal probes on the needle seat 47 and the connecting ports of the detection areas 3 are respectively unlocked, so that the spring 13 arranged on the bottom 150 of the actuator 15 is gradually restored to the initial state , It also drives the actuating member 15 to move away from the detection areas 3 and to the two fixing seats 21 of the two actuating units 20. At the same time, it also allows the two actuating units 20 to drive the support through the connecting rod 23 again. The arm 25 returns to the direction of the initial position until the pressing plate 30 returns to the initial position.

The efficiency of electrical testing, in this way, will greatly improve the overall testing efficiency.

Second, the magnetic fasteners 221 provided on the two pressing rods 22 of the two actuating units 20 of the detection device 100 correspond to the magnetic fasteners 271 provided on the two baffles 27 respectively. The technical feature of the position is that due to the magnetic attraction effect, the two pressing rods 22 of the two actuating units 20 and the second baffle plate 27 are magnetically buckled and fixed, thereby preventing the pressing plate 30 from being electrically detected. The rebound phenomenon occurred during the process, which led to the failure of electrical testing.
