[0058] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a multi-channel SPD process and a finished product testing device.

[0059] Please see Figures 1-8In this embodiment, the system includes: a workbench 1, on which a testing mechanism 2, a control and display device 3, and a power supply device 4 are provided, and the testing mechanism 2, the control and display device 3, and the power supply device 4 are electrically connected; the testing mechanism 2 includes: a testing frame 201, which is disposed on the workbench 1; a placement component 202, which is disposed on the testing frame 201 and is adapted to place multiple test samples; a testing component 203, which is disposed on the testing frame 201 and can rise or fall along the vertical direction of the testing frame 201, and is disposed in the same vertical direction as the placement component 202, so as to test the test samples in the placement component 202; and a driving component 204, which is disposed on the top of the testing frame 201 and can rise or fall along the vertical direction of the testing frame 201, and is connected to the testing component 203, so as to drive the testing component 203 to rise or fall.

[0060] The operator can place multiple test samples inside the plant component of the testing mechanism 2, and then drive the component 204 to descend vertically, thereby driving the testing component 203 to also descend vertically. This allows the testing component 203 to perform DC breakdown voltage, start voltage, and circuit continuity tests on the test samples inside the placement component 202. The test results will be displayed on the control display device 3. The power supply device 4 can control the testing component 203 to energize one or more test samples to ensure the accuracy of the testing component 203.

[0061] The test samples mentioned above can be applicable to products such as varistors, semiconductor discharge tubes, gas discharge tubes, TVS, and SPD.

[0062] In this embodiment, the placement assembly 202 includes: a fixture 2021, which is mounted on the test rack 201 and has a slot at its end; a plurality of first sensors 2022, which are equally spaced within the fixture 2021; and two limiting rods 2023, which are equally spaced at the slot of the fixture 2021. The fixture 2021 has multiple workstations, each capable of holding multiple test samples. Each workstation is equipped with a first sensor 2022, which is a photoelectric sensor. The photoelectric sensor can detect whether there is a test sample at the workstation or detect the position of the test sample. The first sensor 2022 informs the operator of the status of each workstation and can also detect the number of test samples.

[0063] In this embodiment, the test assembly 203 includes: two slide rods 2031, which are vertically mounted on the test frame 201 and spaced apart; two sliding sleeves 2032, which are slidably mounted on the two slide rods 2031; a fixing plate 2033, which is mounted on the two sliding sleeves 2032; a plurality of test pins 2034, which are vertically mounted on the ends of the fixing plate 2033 and spaced equally; a plurality of second sensors 2035, which are vertically mounted at equal intervals on the bottom of the fixing plate 2033 and spaced apart from the test pins 2034; and a connecting frame 2036 on the top of the fixing plate 2033. 6 is connected to the drive assembly 204. When the drive assembly 204 descends vertically, it applies pressure to the fixed plate 2033, causing the fixed plate 2033 to descend vertically along the two slide rods 2031 via the two sliding sleeves 2032, thereby conducting an electrical test on the test sample in the fixture 2021. The second sensor 2035 mentioned above is also a photoelectric sensor. The second sensor 2035 can also check whether there is a test sample or the position of the test sample at the corresponding workstation. The second sensor 2035 can also detect the number of test samples. After the test is completed, the drive assembly 204 rises vertically, and the fixed plate 2033 also rises accordingly, so that the test needle 2034 and the second sensor 2035 move away from the test sample. The sample data after the test is completed will be displayed on the control display device 3.

[0064] In this embodiment, the drive assembly 204 includes: a mounting member 2041, which is disposed on the top of the test frame 201; a handle 2042, one end of which is rotatably connected to the top of the mounting member, and the other end of which is inclined; two connecting members 2043, which are respectively disposed on both sides of the handle 2042, and the first ends of the two connecting members 2043 are rotatably connected to the handle 2042; and a sliding column 2044, which is vertically slidably disposed at the bottom of the mounting member 2041, the second ends of the two connecting members 2043 are respectively rotatably connected to the top of the sliding column 2044, and the bottom of the sliding column 2044 is connected to the connecting frame 2036; when the test assembly 203... When testing the sample inside the storage assembly 202, the operator can hold the handle 2042 and pull it clockwise. This causes the handle 2042 to apply pressure to the sliding column 2044 through the two connectors 2043, causing the sliding column 2044 to descend vertically at the bottom of the mounting component 2041. The sliding column 2044 also applies pressure to the test assembly 203, causing it to descend and test the sample inside the storage assembly 202. After the test is completed, the operator rotates the handle 2042 counterclockwise, causing the two connectors 2043 to pull the sliding column 2044 upward. As the sliding column 2044 rises, it also pulls the test assembly 203 upward.

[0065] In this embodiment, the two connectors 2043 are trapezoidal in shape, and the two connectors 2043 and the top of the mounting member 2041 form a clearance space; so that when the handle 2042 is rotated clockwise or counterclockwise, the two connectors 2043 will not touch the top of the mounting member 2041; while when the handle 2042 is rotated at a larger angle counterclockwise, the two connectors 2043 can hang on the top of the mounting member 2041 to avoid the handle 2042 being rotated clockwise due to the force of the test component 203.

[0066] In this embodiment, the top of the mounting member 2041 is U-shaped, and the bottom of the mounting member 2041 is a through cylindrical shape; the middle of the U-shaped part at the top of the mounting member 2041 is hollow, and the hollow part is for rotational connection with the handle 2042; while the through cylindrical shape at the bottom of the mounting member 2041 is to restrict the movement direction of the sliding column 2444.

[0067] In this embodiment, the end of the test fixture 201 is provided with a plurality of control buttons 2011; the control buttons 2011 can control whether the first sensor 2022, the second sensor 2035 and the test probe 2034 are powered on.

[0068] In this embodiment, the test frame 201 is provided with rotatable handles 2012 on both sides; when it is necessary to move the test mechanism 2, the entire test mechanism 2 can be moved by holding the handles 2012 on both sides of the test frame 201.

[0069] In this embodiment, an alarm 301 is provided on the top of the control display device 3; if the test sample in the fixture 2021 fails the test or the test mechanism 2 malfunctions, the alarm 301 will emit an alarm sound and light to remind the operator that there is an abnormal situation.
