[0015] The present invention provides a functional testing device for terminal block production, which has the following beneficial effects: 1. The present invention utilizes air flow to drive the rotation of a rotating structure composed of a bracket, a rotating cylinder, fan blades and a connecting frame. The rotation of the rotating structure drives the rotation of a rotating structure composed of a first cylinder, a second cylinder and a circular plate. The rotation of the rotating structure causes the air entering the intake pipe to replace the heat generated by the terminal installed between the two partition plates. At the same time, the air temperature is detected after being discharged from the exhaust groove.

[0016] 2. The present invention arranges the speaker grooves on multiple arc-shaped plates on the same straight line in an obliquely staggered manner, so that the first cylinder will only contact one of the speaker grooves during rotation, thereby increasing the number of detectable terminals, and the high-temperature gas after the air around each terminal is replaced by new gas will not contact the gas at other terminals, ensuring the accuracy of detection.

[0017] 3. The present invention installs a vertical cylinder at the center of the circular plate, and installs a rebound structure composed of a movable plate and an elastic part in the vertical cylinder. The rebound structure is used to temporarily store the air entering the first cylinder, so as to avoid the air inlet groove affecting the rotation of the rotating structure when no air is introduced. In the early stage of the operation of the terminal, the temperature rises slowly, and the controller is used to control the contraction of the telescopic end of the electric push rod to reduce the extrusion force on the elastic part. When the air inlet groove cannot take in air, the air entering the air intake pipe squeezes the rebound structure to ensure that the rotating structure continues to rotate. However, when the upward movement amplitude of the rebound structure decreases, the air that can enter the air intake pipe is reduced, which reduces the rotation speed of the rotating structure. Anyway, the rotation speed of the rotating structure is accelerated, so that the temperature detector can control the detection frequency according to the different working hours of the terminal, thereby further ensuring the accuracy of terminal temperature monitoring.

DETAILED DESCRIPTION

[0020] See also Figures 1 to 7 The present invention provides a technical solution: a functional test device for terminal production, comprising a base plate 1, a plurality of annular plates 25 are provided on the upper surface of the base plate 1, and a plurality of connecting rods 12 are installed between the lowest annular plate 25 and the base plate 1, and the annular plates 25 are connected to the base plate 1 by the connecting rods 12, the plurality of annular plates 25 are arranged coaxially, a plurality of partition plates 26 are installed between two adjacent annular plates 25, and the plurality of annular plates 25 are connected by the partition plates 26, a first cylinder 29 and a second cylinder 2 are provided on the upper surface of the base plate 1, the first cylinder 29 is in contact with the inner surface of the annular plate 25, and the second cylinder 2 is in contact with the inner surface of the annular plate The annular outer surfaces of the plate 25 are in contact with each other, and a circular plate 4 is installed on the upper surface of the first cylinder 29 and the second cylinder 2. A plurality of limiting grooves 20 are provided on the annular surface of the circular plate 4, and a plurality of limiting blocks 3 are installed on the upper surface of the second cylinder 2. The limiting blocks 3 are inserted into the limiting grooves 20. An air inlet groove 19 is provided on the side of the first cylinder 29 facing the second cylinder 2, and an exhaust groove 8 is provided on the side of the second cylinder 2 facing the first cylinder 29. The temperature detector 7 is installed at the exhaust groove 8. An annular groove 11 is provided on the upper surface of the bottom plate 1 with the second cylinder 2 at the same center. A plurality of sliders 10 are slidably connected in the annular groove 11, and the sliders 10 are clamped with the second cylinder 2.

[0021] A circular hole 13 is provided on the upper surface of the base plate 1, and an air intake pipe 9 is installed in the circular hole 13. A bracket 17 is installed in the circular hole 13. The bracket 17 is rotatably connected to a rotating cylinder 16 on the side away from the air intake pipe 9. A plurality of fan blades 15 are installed on the annular surface of the rotating cylinder 16. The fan blades 15 are arranged in the air intake pipe 9, and a connecting frame 14 is installed on the end of the rotating cylinder 16 away from the bracket 17. The end of the connecting frame 14 away from the connecting rod 12 is installed in the first cylinder 29. When air is passed into the air intake pipe 9, the air flow drives the fan blades 15 to rotate, and the rotation of the fan blades 15 drives the rotating cylinder 16 to rotate. The rotation of the rotating cylinder 16 drives the bracket 17 to rotate, thereby driving the first cylinder 29 to rotate and the second cylinder 2 to rotate.

[0022] The air flow is utilized to drive the rotating structure composed of the bracket 17, the rotating cylinder 16, the fan blades 15 and the connecting frame 14 to rotate. The rotation of the rotating structure drives the rotating structure composed of the first cylinder 29, the second cylinder 2 and the circular plate 4 to rotate. The rotation of the rotating structure causes the air entering the air intake pipe 9 to replace the heat generated by the terminal installed between the two partition plates 26. At the same time, the air temperature is detected after being discharged from the exhaust groove 8. Since the rotating structure is driven to rotate by the rotating structure during this process, the temperature generated after the operation of multiple terminal blocks can be detected.

[0023] An arc-shaped plate 28 is installed between multiple partition plates 26. The arc-shaped plate 28 is in sliding contact with the annular surface of the first cylinder 29. A horn groove 27 in contact with the first cylinder 29 is provided on the side of the arc-shaped plate 28 away from the first cylinder 29. The horn grooves 27 provided on multiple arc-shaped plates 28 on the same straight line are arranged in an obliquely staggered manner, that is, the horn grooves 27 on two adjacent arc-shaped plates 28 are not on the same vertical line.

[0024] By staggering the speaker slots 27 on multiple arc-shaped plates 28 on the same straight line, the first cylinder 29 will only contact one of the speaker slots 27 during rotation, thereby increasing the number of detectable terminals. In addition, the high-temperature gas around each terminal will not come into contact with the gas at other terminals after the air is replaced by new gas, thereby ensuring the accuracy of detection.

[0025] A through hole is provided on the upper surface of the circular plate 4, in which a vertical cylinder 5 is rotatably connected. A ventilation groove 6 is provided on the upper surface of the vertical cylinder 5, and a support rod 18 is installed on the top of the vertical cylinder 5. The end of the support rod 18 away from the vertical cylinder 5 is inserted in the rotating cylinder 16 and connected to the bracket 17. A movable groove 30 is provided on the annular surface of the support rod 18, and a movable plate 21 is slidably connected to the annular surface of the movable groove 30. The movable plate 21 is slidably connected to the annular inner surface of the vertical cylinder 5. A plurality of elastic members 22 are installed on the side of the movable plate 21 facing the top of the vertical cylinder 5. The elastic member 22 is a spring. The elastic member 22 is in a compressed state, and the end of the elastic member 22 away from the movable plate 21 is installed in the vertical cylinder 5.

[0026] An electric push rod 24 is installed at the top of the vertical cylinder 5, and a pressure plate 23 is movably installed on the electric push rod 24. The end of the elastic member 22 away from the movable plate 21 is connected to the pressure plate 23. The signal output end of the temperature sensor is connected to the controller. The controller controls the extension and retraction of the movable end of the electric push rod 24 by measuring the temperature through the temperature sensor. The working principle of the controller is to estimate the temperature detected by the temperature sensor. When the temperature detector 7 detects that the temperature rises, the controller controls the telescopic end of the electric push rod 24 to gradually retract.

[0027] By installing a vertical cylinder 5 at the center of the circular plate 4 and installing a rebound structure composed of a movable plate 21 and an elastic member 22 in the vertical cylinder 5, the rebound structure is used to temporarily store the air entering the first cylinder 29, so as to prevent the air inlet groove 19 from affecting the rotation of the rotating structure when no air is introduced. In addition, in the early stage of the operation of the terminal, the temperature rises slowly, and the controller is used to control the telescopic end of the electric push rod 24 to contract, so that the extrusion force on the elastic member 22 is reduced. When the air inlet groove 19 cannot take in air, the air entering the air inlet pipe 9 squeezes the rebound structure to ensure that the rotating structure continues to rotate. However, when the upward movement amplitude of the rebound structure decreases, the amount of air that can enter the air inlet pipe 9 is reduced, which reduces the speed of the rotating structure. Anyway, the speed of the rotating structure is accelerated, so that the temperature detector 7 can control the detection frequency according to the different working time of the terminal, further ensuring the accuracy of terminal temperature monitoring.

[0028] In summary, when using this functional testing device for terminal production, first take out the second cylinder 2 from the circular plate 4, separate the second cylinder 2 from the slider 10, and then install the terminal in sequence on the annular plate 25 between the two partition plates 26 and power on, then start the extension of the telescopic end of the electric push rod 24 to put the elastic member 22 in a compressed state, and then use a blower such as a fan or an air pump to introduce air from the air inlet pipe 9, the air flow drives the fan blades 15 to rotate, the rotation of the fan blades 15 drives the rotating cylinder 16 to rotate, the rotation of the rotating cylinder 16 drives the bracket 17 to rotate, and after the bracket 17 rotates, it drives the rotating structure composed of the first cylinder 29, the second cylinder 2 and the circular plate 4 to rotate.

[0029] During the rotation process, the first cylinder 29 drives the air intake groove 19 provided on the first cylinder 29 to contact multiple speaker grooves 27 in sequence. After each contact with the speaker groove 27, the air introduced into the air intake pipe 9 replaces the heated air around the terminal block. The heated air is discharged through the exhaust groove 8 and detected by the temperature detector 7, thereby completing the detection of the temperature of the terminal block during operation.

[0030] At the initial stage of detection, the temperature of the terminal block is low, and the telescopic end of the electric push rod 24 extends to squeeze the elastic member 22, causing the air intake groove 19 to not contact the speaker groove 27. The air entering the air intake pipe 9 can only squeeze the movable plate 21, causing the movable plate 21 to further squeeze the elastic member 22, ensuring that the air in the air intake pipe 9 enters the first cylinder 29 and drives the rotating structure to rotate. However, since the elastic member 22 has been squeezed by the electric push rod 24, the amount of air entering the air intake pipe 9 is reduced, the rotation speed of the rotating structure is low, and the rotation speed of the rotating structure is reduced, so that the heat generated when the terminal block is working accumulates more, which is more convenient for detection by the temperature detector 7.

[0031] As the working time of the terminal increases, the temperature of the terminal increases rapidly. At this time, the temperature detector 7 detects that the temperature of the replaced air has increased and transmits the signal to the controller. The controller controls the telescopic end of the electric push rod 24 to contract, thereby reducing the pressure of the elastic member 22. At this time, the air entering the air intake pipe 9 increases and squeezes the movable plate 21, causing the movable plate 21 to move toward the vertical cylinder 5. The distance moved by the vertical cylinder 5 increases, and more air enters the vertical cylinder 5. At the same time, the amount of air that can enter increases, and the rotating structure drives the rotating structure to increase its rotation speed, thereby accelerating the detection frequency of each terminal by the temperature detector 7, further ensuring the accuracy of terminal temperature monitoring.
