When the main board is pressed down, the installed electronic component can press down the push rod and press it on the button. If the push rod is completely pressed on the button, it is regarded as qualified.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 4As shown, a device for detecting missing components of an audio and video mainboard comprises a main body 1, wherein an installation frame 2 is fixedly arranged in the middle of the main body 1, and a push rod 3 is slidably arranged in the middle of the installation frame 2, a limit shaft 4 is rotatably arranged at the lower end of the push rod 3, and a rotating shaft 5 is fixedly arranged at the upper end of the limit shaft 4, the upper end of the rotating shaft 5 is rotatably connected with the push rod 3, and a spring 6 is fixedly arranged around the rotating shaft 5 inside the push rod 3. Before detecting the mainboard, the push rod 3 is first lifted and then rotated by the rotating shaft 5, so that the limit shaft 4 below is clamped into the card slot 7, so that the push rod 3 at the electronic component is in a position to be triggered, and when the mainboard is pressed down, the installed electronic component can press the push rod 3 down and press it onto the button 8. If all the push rods 3 are pressed onto the button 8, it is considered qualified, and when the button 8 is not triggered, it is considered unqualified, because when no electronic component is installed at the corresponding position on the mainboard, the push rod 3 cannot be pressed onto the button 8, so that the mainboard can be detected intuitively;

[0026] Furthermore, the material of the push rod 3 and other related components is set to plastic because plastic is light and has an insulating effect. This eliminates the need to install a spring 6 with high stress, thereby ensuring that the mainboard will not be damaged by extrusion or static electricity during testing.

[0027] like Figure 1 , Figure 5-Figure 6As shown in the figure, a card slot 7 is provided around the push rod 3 on the inner side of the installation frame 2. The limiting shaft 4 is rotatably connected to both the installation frame 2 and the card slot 7 at the same time. A button 8 is provided at the lower end of the push rod 3, and the button 8 is fixedly connected to the main body 1. The push rod 3, the limiting shaft 4 and the rotating shaft 5 are all made of plastic. Installation seats 9 are fixedly provided on both sides of the main body 1, and a first camshaft 10 is rotatably provided on the opposite side of the installation seat 9. A second spring 11 is fixedly provided inside the first camshaft 10, and two second springs 11 are symmetrically arranged along the center line of the first camshaft 10. The outer end of the second spring 11 is fixedly provided with a limiting disc 12, and the limiting disc 12 is simultaneously slidably connected to the first camshaft 10. A gear 13 is fixedly provided on the outside of the limiting disc 12, and the gear 13 is simultaneously slidably connected to the first camshaft 10. The gear 13 is connected to the driving component inside the installation seat 9. A chute 15 is provided at the lower end of the first camshaft 10, and two chutes 15 are symmetrically arranged along the center line of the main body 1. The chute 15 is arranged in a "C" shape. Elastic components 14 are fixedly provided on both sides at the lower end of the chute 15. Support plates 16 are fixedly provided on both sides of the main body 1, and a conveyor belt 17 is provided on one side of the support plate 16. A telescopic base 18 is provided in the middle of the conveyor belt 17, and a stopper 19 is fixedly provided at the upper end of the telescopic base 18. The stopper 19 is made of rubber, and a belt 20 is rotatably provided on the side of the stopper 19 away from the main body 1. Second camshafts 21 are provided on both sides of the lower end of the stopper 19 and located at the telescopic base 18, and the second camshafts 21 are connected to the driving component inside the installation seat 9 through a chain 22. After the object rotates into the chute 15, it can be pressed down as the first camshaft 10 rotates to detect the main board. And when the detection speed is different, different specifications of the first camshaft 10 can be replaced. When replacing, push the gear 13 towards the middle through the installation seat 9 until it completely disengages from the installation seat 9. In this way, it is convenient for the device to adapt to different detection speeds, thereby improving the working efficiency and detection accuracy of the device; the main board is transported through the conveyor belt 17. When the first camshaft 10 presses down the chute 15, the second camshaft 21 can lift the stopper 19 through the chain 22, so that the main board on the conveyor belt 17 can be separated, avoiding blockage of the passage or damage to the main board due to overcrowding when the main board enters the chute 15. And when the stopper 19 rises, if a main board happens to move to one side of it, the belt 20 can prevent the main board from resting on one side of the stopper 19, thereby avoiding damage to the main board by the conveyor belt 17.

[0028] Further, the stopper 19 is made of rubber, so that when the stopper 19 lifts a certain main board, it can, to a certain extent, prevent the main board from passing over.

[0029] Working principle: When using the audio and video mainboard component missing detection device, first, before detecting the mainboard, lift the push rod 3 through the rotating shaft 5 and then rotate it, so that the lower limit shaft 4 is stuck in the card slot 7, so that the push rod 3 at the electronic component can be in the position to be triggered. When the mainboard is pressed down, the installed electronic component can press the push rod 3 down and press it onto the button 8. If all the push rods 3 are pressed onto the button 8, it is considered qualified. When the button 8 is not triggered, it is considered unqualified, because when the electronic component is not installed at the corresponding position on the mainboard, the push rod 3 cannot be pressed onto the button 8, so that the mainboard can be detected intuitively; secondly, after entering the slide groove 15, the camshaft 10 can be pressed down as it rotates to detect the mainboard, and when the detection speed At the same time, camshaft 10 of different specifications can be replaced. When replacing, the gear 13 is pushed toward the middle through the mounting seat 9 until it is completely separated from the mounting seat 9, which can facilitate the device to adapt to different detection speeds, thereby accelerating the working efficiency and detection accuracy of the device; finally, the mainboard is transported by the conveyor belt 17. When the camshaft 10 presses down the chute 15, the camshaft 21 can be used through the chain 22 to lift the block 19, so that the mainboard on the conveyor belt 17 can be separated to prevent the mainboard from being blocked or damaged due to being too dense when entering the chute 15. When the block 19 is raised, if there is a mainboard moving to one side, the belt 20 can prevent the mainboard from being placed on one side of the block 19, thereby preventing the conveyor belt 17 from damaging the mainboard. This is the working principle of the audio and video mainboard component missing detection device.
