Description
Technical Field
[0001] The present application relates to the field of digital tubes, and in particular to a detection device for digital tubes. Background Art
[0002] A digital tube, also known as a Nixie tube, is an electronic device that can display numbers and other information. The glass tube includes an anode made of a metal mesh and multiple cathodes. Most digital tube cathodes are in the shape of numbers. The tube is filled with low-pressure gas, usually mostly neon with some mercury and / or argon. When a cathode is charged, the digital tube will emit colored light, depending on the gas in the tube, usually orange or green. LED digital tubes (LED Segment Displays) are devices composed of multiple light-emitting diodes packaged together to form an "8" shape. The leads have been connected internally, and only their strokes and common electrodes need to be led out. The number of segments commonly used in LED digital tubes is generally 7, and some have an additional decimal point.
[0003] The pins of the LED lamp beads in the digital tube need to be soldered to the PCB board to complete the circuit connection. In order to ensure the stable performance of the digital tubes produced in batches, the digital tubes are generally inspected, and their pins are soldered to the PCB board. Then the PCB board is powered on to verify whether all the lamp beads can emit light. The current detection device generally needs to insert the pins of the digital tube into the corresponding openings of the detection socket to connect the pins to the PCB board. However, the pins of the digital tube are generally located at the bottom of the digital tube. Due to the obstruction of the digital tube shell and the small pins, it is difficult to align the pins. In addition, for some digital tubes with round shells, the "8"-shaped pattern on the digital tube is symmetrical up and down, making it difficult to distinguish the upper and lower sides of the digital tube. When the digital tube is placed on the detection socket, it is easy to turn it upside down, which makes it impossible to insert the pins. Utility Model Content

[0013] Preferably, a variable resistor is also provided on the PCB board, and the variable resistor is used to change the voltage of the digital tube during detection.

[0026] The present application discloses a digital tube detection device, such as Figure 1 and Figure 2 As shown, it includes a detection seat 1, a first positioning groove 2 and a second positioning groove 3 are provided on the detection seat 1, a first positioning block 21 and a second positioning block 31 are provided at the bottom of the housing of the digital tube 11, the shape of the first positioning groove 2 is different from the shape of the second positioning groove 3, and the first positioning groove 2 is matched with the shape of the first positioning block 21, and the shape of the second positioning groove 3 is matched with the shape of the second positioning block 31, the first positioning block 21 and the second positioning block 31 are respectively used to insert the first positioning groove 2 and the second positioning groove 3, the detection seat 1 is also provided with a PCB board 4 and a switch 5, and the PCB board 4 is provided with a plurality of connection holes 6 for connecting with the pins 12 of the digital tube 11, when the digital tube 11 is placed on the detection seat 1, the first positioning block 21 and the first positioning block 31 are connected. The positioning groove 2 is aligned and the second positioning block 31 is aligned with the second positioning groove 3, so as to determine the position and direction of the digital tube 11. At this time, the pin 12 of the digital tube 11 is inserted into the connecting hole 6 on the PCB board 4. When the first positioning block 21 and the second positioning block 31 are respectively inserted into the first positioning groove 2 and the second positioning groove 3, the pin 12 is connected with the connecting hole 6 on the PCB board 4, so as to complete the connection between the pin 12 and the PCB board 4. The digital tube 11 can be tested by turning on the power supply and the switch 5. The setting of the first positioning block 21, the first positioning groove 2, the second positioning block 31 and the second positioning groove 3 makes it easier for the staff to align the pin 12 of the digital tube 11 with the detection seat 1, thereby reducing the situation where the digital tube 11 is upside down.
[0027] In this embodiment, the first positioning block 21 and the second positioning block 31 are both arranged as arc-shaped blocks, and the length of the first positioning block 21 is greater than that of the second positioning block 31. The first positioning groove 2 and the second positioning groove 3 respectively match the shapes of the first positioning block 21 and the second positioning block 31. The number of the second positioning blocks 31 is specifically two. The first positioning block 21 and the two second positioning blocks 31 are evenly distributed on the outer periphery of the bottom of the digital tube 11. The angle between the three positioning blocks is 120°. The first positioning block 21 and the second positioning block 31 can also be used as support feet for the digital tube 11. Both of them are arc-shaped blocks but have inconsistent lengths, which can also ensure the direction of the digital tube 11 inserted into the detection seat 1.
[0028] In order to make the pin 12 better connected with the PCB board 4 after being inserted into the connection hole 6, as shown in FIG. Figure 3 and Figure 4 As shown, a clamping assembly is provided at the bottom of the PCB board 4, and the clamping assembly is located below the connecting hole 6. The clamping assembly is used to contact and press the pin 12 of the digital tube 11. The setting of the clamping assembly can press the pin 12 so that the connection between the pin 12 of the digital tube 11 and the PCB board 4 is tighter to ensure that it is powered on. The clamping assembly includes a clamping piece 7 and a mounting seat 8. The mounting seat 8 is fixedly installed on the bottom surface of the PCB board 4 and is located on one side of the connecting hole 6. The clamping piece 7 is inserted on the side of the mounting seat 8 facing the connecting hole 6, and two springs 9 are provided between the clamping piece 7 and the mounting seat 8. The two springs 9 are respectively located on both sides of the clamping piece 7. One end of the spring 9 is fixed in the mounting seat 8, and the other end of the spring 9 is fixed on the side of the clamping piece 7 facing the mounting seat 8. The upper part of the side of the fastening member 7 facing away from the mounting seat 8 is inclined and has a plurality of arc grooves 10. The arc grooves 10 are used to abut the pin 12 of the digital tube 11. When the pin 12 is inserted, the upper part of the fastening member 7 first contacts the lower end of the pin 12. Since the upper part of the fastening member 7 is inclined, the spring 9 is guided to be compressed, so that the fastening member 7 moves toward the mounting seat 8, making the insertion of the pin 12 more convenient and smooth. The pin 12 is placed in the arc groove 10 after passing through. Under the action of the spring 9, the fastening member 7 abuts the pin 12 inserted into the socket, so that the pin 12 maintains good contact with the hole wall of the socket, and the connection between the pin 12 and the PCB board 4 is tighter, while it is convenient to pull out the pin 12. The mounting seat 8 and the fastening member 7 are both made of insulating material.
[0029] A variable resistor is also provided on the PCB board 4. The variable resistor is used to change the voltage of the digital tube 11 during detection. The variable resistor allows the detection voltage of the LED lamp beads of the digital tube 11 to be adjusted as needed during detection, simulating the situation where the voltage of the LED lamp beads suddenly changes when in use. It can further detect whether the LED lamp beads will be affected by the voltage change and cause damage. The detection socket 1 is externally connected to a controller and a display screen. The controller is connected to the PCB board 4. The controller is used to change the resistance value of the variable resistor. The display screen can better display the current voltage and current state of the digital tube 11 and record the detection results of the digital tube 11.
[0030] The implementation principle of this embodiment is:
[0031] When the digital tube 11 is placed on the detection seat 1, the first positioning block 21 is aligned with the first positioning groove 2 and the second positioning block 31 is aligned with the second positioning groove 3, so as to determine the position and direction of the digital tube 11. At this time, the pin 12 of the digital tube 11 is aligned with the connection hole 6 on the PCB board 4. When the first positioning block 21 and the second positioning block 31 are respectively inserted into the first positioning groove 2 and the second positioning groove 3, the pin 12 is inserted into the connection hole 6 on the PCB board 4. The fastening member 7 presses against the pin 12 inserted into the jack under the action of the spring 9, so that the pin 12 maintains good contact with the hole wall of the jack, and the pin 12 is tightly connected to the PCB board 4, thereby completing the connection between the pin 12 and the PCB board 4. Turn on the power supply and the switch 5 to detect the digital tube 11.
