Description

Technical Field

[0001] This utility model relates to the field of DC terminal testing technology, specifically to an automatic DC terminal testing device. Background Technology

[0002] Existing automated testing equipment requires precise plugging and unplugging of the device under test (DUT) into the terminals of the testing system during testing operations. This step has traditionally relied on manual operation, where operators manually insert the plug into the designated terminals to establish the necessary electrical connection and ensure smooth testing. To improve the automation level and efficiency of testing, some advanced testing equipment has begun to adopt automatic plugging and unplugging mechanisms to replace the traditional manual method.

[0003] According to a patent application published on the internet (authorization announcement number: CN209571642U), "This utility model discloses an automatic terminal detachment device, including a main panel, a movable plate, terminals, a positioning shaft, and a drive unit; the main panel has an insertion hole, one end of the terminal is fixedly connected to the movable plate, and the other end of the terminal can extend and retract into the insertion hole; one end of the positioning shaft is fixedly connected to the main panel, the positioning shaft passes through the movable plate, and the movable plate is slidably connected to the positioning shaft; the drive unit is driven and connected to the movable plate, and the direction of movement of the movable plate is consistent with the sliding direction of the movable plate on the positioning shaft. The automatic terminal detachment device provided by this utility model drives the movable plate away from the main panel through the drive unit, thereby causing the terminal to change from being inserted into the insertion hole to being retracted from the insertion hole, thus separating the terminal from the plug of the device under test. The automatic terminal detachment device provided by this embodiment can realize the automatic separation of the plug and the terminal, saving the time and effort of manual removal and improving testing efficiency."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The automatic terminal disconnection device includes a main panel, a moving plate, terminals, a positioning shaft, and a drive unit. This device can automatically separate the plug and the terminal to save time and effort in manual removal and improve testing efficiency. However, when the device separates the terminal and plug through the drive unit, the cover plate may fall off due to excessive ejection, which may damage the device. Utility Model Content

[0006] The purpose of this invention is to provide an automatic DC terminal detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic DC terminal detection device, comprising a main panel, wherein a foolproof frame is installed on the inner side of the main panel, and the surface of the foolproof frame is provided with a placement opening;

[0008] An anti-drop frame is fixedly connected to the left and right ends of the inner side of the placement port. A small sliding rod is fixedly connected to the center of the inner side of the anti-drop frame. A sliding sleeve is slidably connected to the surface of the small sliding rod. A PIN removal cover plate is installed inside the sliding sleeve. A spring is sleeved on the surface of the small sliding rod. When the test terminal needs to be detached, the device uses a cylinder to drive the PIN removal cover plate to pop out, thus automatically separating the DC terminal inserted inside the terminal socket. This eliminates the need for testers to manually pull out the test terminals one by one, resulting in less overall energy consumption. This device effectively improves the overall efficiency of DC terminal testing. During the popping process, the sliding sleeve moves on the surface of the small sliding rod. The anti-drop frame and the small sliding rod limit the popping position to ensure that the terminal does not fall off. The spring reduces the popping force, further preventing excessive popping and thus improving the overall efficiency of the device.

[0009] Preferably, the placement port is provided in four sets, the top and bottom of the sliding sleeve are provided with springs, and the pin removal cover is provided in four sets.

[0010] Preferably, the top front end of the foolproof frame is provided with a PASS / FALL indicator light, and there are four sets of PASS / FALL indicator lights. The PIN removal cover is located inside the placement opening.

[0011] Preferably, the bottom rear end of the error-proof frame is equipped with a cylinder, and four sets of cylinders are provided.

[0012] Preferably, the cylinder is connected to the pin removal cover plate, and the pin removal cover plate is controlled by the cylinder.

[0013] Preferably, the surface of the PIN removal cover plate has three sets of terminal sockets, and the left and right sides inside the placement port are provided with anti-drop frames, small sliding rods, sliding sleeves and springs, which are symmetrically distributed.

[0014] Compared with the prior art, the present invention provides an automatic detection device for DC terminals, which has the following advantages:

[0015] 1. The automatic DC terminal testing device is equipped with an anti-drop frame. When the test terminal needs to be detached, the device uses cylinder 11 to drive the pin-removing cover 8 to pop out, thus automatically separating the DC terminal inserted inside the terminal socket 10. This eliminates the need for testers to manually pull out the test terminals one by one, resulting in less overall energy consumption. This device effectively improves the overall efficiency of DC terminal testing. During the popping process, the sliding sleeve moves on the surface of the small sliding rod. The anti-drop frame and the small sliding rod limit the popping position to ensure that the terminal will not fall off. The spring setting reduces the popping force, further preventing excessive popping and thus improving the overall efficiency of the device. Attached Figure Description

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-5 An automatic detection device for DC terminals includes a main panel 1, a foolproof frame 2 installed on the inner side of the main panel 1, and a placement opening 4 on the surface of the foolproof frame 2.

[0028] An anti-drop frame 5 is fixedly connected to the left and right ends of the inner side of the placement port 4. A small slide rod 6 is fixedly connected to the center of the inner side of the anti-drop frame 5. A sliding sleeve 7 is slidably connected to the surface of the small slide rod 6. A PIN removal cover plate 8 is installed inside the sliding sleeve 7. A spring 9 is sleeved on the surface of the small slide rod 6. When the test terminal needs to be removed, the device drives the PIN removal cover plate 8 to pop out through the cylinder 11, which pops out the DC terminal inserted inside the terminal socket 10, realizing automatic separation. It does not require the tester to manually pull out the test terminals one by one, and the overall consumption is less. The device can effectively improve the overall efficiency of DC terminal testing. During the pop-out process, the sliding sleeve 7 moves on the surface of the small slide rod 6. The anti-drop frame 5 and the small slide rod 6 limit the pop-out position to ensure that it will not fall off. The spring 9 can reduce the pop-out force and further prevent excessive pop-out, thereby improving the overall efficiency of the device.

[0029] The placement port 4 is provided with four sets, the top and bottom of the sliding sleeve 7 are provided with springs 9, and the pin removal cover plate 8 is provided with four sets;

[0030] The top front end of the foolproof frame 2 is equipped with a PASS / FALL indicator light 3, and there are four sets of PASS / FALL indicator lights 3. The PIN removal cover 8 is located inside the placement opening 4.

[0031] The bottom rear end of the foolproof frame 2 is equipped with a cylinder 11, and there are four sets of cylinders 11.

[0032] The cylinder 11 is connected to the pin removal cover 8, and the pin removal cover 8 is controlled by the cylinder 11;

[0033] The surface of the PIN removal cover plate 8 has three sets of terminal sockets 10. The left and right sides inside the placement port 4 are equipped with anti-drop frames 5, small sliding rods 6, sliding sleeves 7 and springs 9, which are symmetrically distributed.

[0034] In actual operation, when using this device, insert the product's DC output head into the DC terminal to begin testing. The device operates independently through eight channels, with four independent cylinders on each side. After testing, the device outputs a DC 12V signal for 1 second to activate the solenoid valve. The PASS / FALL indicator light 3 will indicate the product's connection and testing status. For defective products, the indicator light is red; cylinder 11 does not operate and does not disconnect the pin. For good products, the indicator light is green; the solenoid valve drives cylinder 11 to lift the terminal fixing cover, disengaging the DC head from the terminal pin, the DC 12V signal disappears, and cylinder 11 resets. This device is used when testing is required. When the terminal is detached, the cylinder 11 drives the PIN release cover 8 to pop out, which automatically separates the DC terminal inserted inside the terminal socket 10. This eliminates the need for testers to manually pull out the test terminals one by one, resulting in less overall energy consumption. This device effectively improves the overall efficiency of DC terminal testing. During the pop-out process, the sliding sleeve 7 moves on the surface of the small sliding rod 6. The anti-drop frame 5 and the small sliding rod 6 limit the pop-out position to ensure that it will not fall off. The spring 9 reduces the pop-out force to further prevent excessive pop-out, thereby improving the overall efficiency of the device.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
