A digital tube testing device and its testing method

Abstract

This invention discloses a digital tube testing device and method, relating to the field of digital tube testing technology. The invention includes a testing box and a fixed testing assembly. The digital tube is placed on the top surface of a movable mounting plate with the pins facing upwards. A lifting mounting block moves downwards, causing a fixed arc block and a moving arc block to move to both sides of the digital tube pins. A moving push plate moves towards the movable mounting plate, thereby driving the moving arc block towards the fixed arc block. The moving and fixed arc blocks press and fix the digital tube pins. After fixing, the lifting mounting block moves vertically above a vision inspection instrument. The lifting testing plate moves downwards and contacts the digital tube pins, energizing the digital tube. The vision inspection instrument moves below the digital tube, clamping and fixing the digital tube pins for energization testing. This avoids inserting the digital tube pins into the power socket, reducing wear on the digital tube and lowering the defect rate.

Description

Technical Field

[0001] This invention belongs to the field of digital tube testing technology, and specifically relates to a digital tube testing device and its testing method. Background Technology

[0002] Digital tubes, also known as glow tubes or LED digital tubes, are electronic devices that can display information such as numbers, letters, and symbols. They are widely used in electronics, electrical engineering, automobiles, transportation, environmental protection and other fields.

[0003] During the testing process of digital tubes, the pins of the digital tubes need to be inserted into the power sockets to make the digital tubes work, thereby testing the quality of the digital tubes. However, when the pins of the digital tubes are inserted into the sockets, they are prone to wear and other damage, which increases the defect rate. Manual inspection of the tightness of the pins of digital tubes is cumbersome. Usually, collective inspection is used, that is, all pins are inspected for tightness at the same time. The inspection efficiency is low, and some unqualified pins are prone to pass the inspection, resulting in poor inspection effect. Summary of the Invention

[0014] Preferably, a detection and positioning block is fixedly installed on the top surface of the movable mounting plate.

[0015] A method for testing digital tubes, using the aforementioned digital tube testing equipment, includes the following steps:

[0016] The digital tube is placed on the top surface of the movable mounting plate with the pins facing upwards. The movable mounting plate moves so that several fixed arc blocks and movable arc blocks of the two fixed detection units are directly above the pins of the digital tube. The lifting mounting block moves downwards, so that the fixed arc blocks and movable arc blocks move to the sides of the pins of the digital tube. The movable push plate moves towards the movable mounting plate, thereby driving the movable arc blocks towards the fixed arc blocks.

The lifting detection plate moves downwards and contacts the pins of the digital tube and powers on the digital tube. The vision inspection instrument moves to below the digital tube.

[0017] After the power-on test is completed, the lifting test plate moves upward, and the moving stop moves to fix the position of a set of fixed structure moving arc blocks. The moving push plate moves to drive the unfixed moving arc blocks away from the fixed arc blocks. At this time, only a single pin of the digital tube is fixed. The laser detector moves downward to drive the lifting test plate to rotate, and the lifting extrusion rod moves to below the lifting test plate. The lifting test plate presses down on the lifting extrusion rod, and the lifting extrusion rod presses the digital tube. The laser detector detects the displacement of the digital tube. After the extrusion is completed, the lifting test plate moves upward, and the moving push plate moves to drive the moving arc blocks closer to the fixed arc blocks. The moving stop moves to fix the position of another set of unfixed fixed structure moving arc blocks. This process is repeated to perform the pin fixing test on the digital tube in sequence.

[0018] Compared with the prior art, the present invention provides a digital tube testing device and its testing method, which has the following beneficial effects:

[0019] 1. Place the digital tube with the pins facing upwards on the top surface of the movable mounting plate. Move the movable mounting plate so that several fixed arc blocks and moving arc blocks of the two fixed detection units are directly above the pins of the digital tube. Move the lifting mounting block downwards so that the fixed arc blocks and moving arc blocks are on both sides of the pins of the digital tube. Move the moving push plate towards the movable mounting plate, thereby driving the moving arc blocks towards the fixed arc blocks. The moving arc blocks and fixed arc blocks squeeze and fix the pins of the digital tube. After fixing, the lifting mounting block moves vertically to above the vision inspection instrument. The lifting detection plate moves downwards and contacts the pins of the digital tube and powers on the digital tube. The vision inspection instrument moves below the digital tube and clamps and fixes the pins of the digital tube for power-on testing. This avoids inserting the pins of the digital tube into the power socket, reducing wear on the digital tube and lowering the defect rate.

[0020] 2. After the power-on test is completed, the lifting test plate moves upward, and the moving stop moves to fix the position of a set of fixed structure moving arc blocks. The moving push plate moves to drive the unfixed moving arc blocks away from the fixed arc blocks. At this time, only a single pin of the digital tube is fixed. The laser detector moves downward to drive the lifting test plate to rotate, and the lifting extrusion rod moves to below the lifting test plate. The lifting test plate presses down on the lifting extrusion rod, and the lifting extrusion rod presses the digital tube. The laser detector detects the displacement of the digital tube. After the extrusion is completed, the lifting test plate moves upward, and the moving push plate moves to drive the moving arc blocks closer to the fixed arc blocks. The moving stop moves to fix the position of another set of unfixed fixed structure moving arc blocks. This process is repeated to perform the pin fixing test on the digital tube in sequence. The pins of the digital tube are then tightened in sequence to improve the testing efficiency and effectively prevent digital tubes with improperly fixed pins from passing the tightening test, which would affect subsequent production and sales.

[0021] 3. Place the digital tube on the detection and positioning block for easy positioning.

[0053] In use, the lifting motor 106 drives the lifting screw 104 to rotate, the rotation of the lifting screw 104 causes the lifting mounting plate 105 to move vertically, and the lifting mounting plate 105 causes the lifting mounting block 201 to move vertically.

[0054] Please see Figure 1 - Figure 11 The fixed detection assembly 2 also includes a rotating mounting block 219, a mounting rotating plate 220, a rotating motor 221, a lifting spring 222, and a lifting extrusion plate 223. The rotating mounting block 219 is fixedly installed on the side of the lifting mounting frame 103. A rotating mounting groove is opened on the side of the rotating mounting block 219. The mounting rotating plate 220 is rotatably installed in the rotating mounting groove. A lifting mounting groove is opened on the side of the mounting rotating plate 220. The lifting extrusion plate 223 is slidably installed in the lifting mounting groove. A lifting spring 222 is fixedly installed on the top surface of the lifting mounting groove. The top end of the lifting spring 222 is fixedly connected to the top end of the inner wall of the lifting mounting groove. A lifting extrusion rod 204 is fixedly installed on the bottom surface of the lifting extrusion plate 223. A vision inspection instrument 205 is fixedly installed on the side of the mounting rotating plate 220. The rotating motor 221 is fixedly installed on the top surface of the rotating mounting block 219. The drive shaft of the rotating motor 221 passes through the rotating mounting block 219 and is fixedly connected to the mounting rotating plate 220.

[0055] During use, when the power-on test is performed, the rotating motor 221 drives the mounting rotating plate 220 to rotate, causing the vision inspection instrument 205 to move below the digital tube. At this time, the lifting and pressing plate 223 has not moved between the movable mounting plates 301. When the fastening test is performed, the lifting and pressing plate 223 moves into the space between the movable mounting plates 301, and the buffer pressing plate 214 presses the lifting and pressing plate 223. The lifting and pressing plate 223 drives the lifting and pressing rod 204 to press the digital tube body downward.

[0056] Please see Figure 1 - Figure 11 The movable lead screw 206 is a bidirectional threaded lead screw, and an electric plate is fixedly installed on the bottom surface of the lifting detection plate 202.

[0057] Please see Figure 1 - Figure 11 A detection and positioning block 107 is fixedly installed on the top surface of the movable placement plate 101;

[0058] When in use, place the digital tube on the detection and positioning block 107 for easy positioning.

[0059] A method for testing digital tubes, using the aforementioned digital tube testing equipment, includes the following steps:

[0060] The digital tube is placed on the top surface of the movable mounting plate 101 with the pins facing upwards. The movable mounting plate 301 moves so that several fixed arc blocks 401 and movable arc blocks 402 of the two fixed detection units 3 are located directly above the pins of the digital tube. The lifting mounting block 201 moves downwards so that the fixed arc blocks 401 and movable arc blocks 402 move to the sides of the pins of the digital tube. The movable push plate 302 moves towards the movable mounting plate 301, thereby driving the movable arc blocks 402 towards the fixed arc blocks 401. The movable arc blocks 402 and fixed arc blocks 401 press and fix the pins of the digital tube. After fixing, the lifting mounting block 201 moves vertically to above the vision inspection instrument 205. The lifting detection plate 202 moves downwards and contacts the pins of the digital tube and powers on the digital tube. The vision inspection instrument 205 moves to below the digital tube.

[0061] After the power-on test is completed, the lifting test plate 202 moves upward, and the moving stop 303 moves to fix the position of the moving arc block 402 of a set of fixed structures 4. The moving push plate 302 moves to drive the unfixed moving arc block 402 to move away from the fixed arc block 401. At this time, only a single pin of the digital tube is fixed. The laser detector 203 moves downward to drive the lifting test plate 202 to rotate. The lifting extrusion rod 204 moves to below the lifting test plate 202. The lifting test plate 202 presses the lifting extrusion rod 204 downward, and the lifting extrusion rod 204 presses the digital tube. The laser detector 203 detects the displacement of the digital tube. After the extrusion is completed, the lifting test plate 202 moves upward, and the moving push plate 302 moves to drive the moving arc block 402 to move closer to the fixed arc block 401. The moving stop 303 moves to fix the position of the moving arc block 402 of another set of unfixed fixed structures 4. This process is repeated to fix the pins of the digital tube in sequence.
