Description

Technical Field

[0001] The utility model relates to the technical field of ESD testing, and particularly provides an ESD test inspection device. Background Technique

[0002] ESD testing refers to electrostatic discharge testing, which is a test that all electronic devices must pass. Its purpose is to simulate the discharge generated when an operator or an object contacts the device and the discharge of a person or an object to a neighboring object, so as to detect the anti-electrostatic discharge interference ability of the device under test;

[0003] The published patent number "CN113484647A" provides a power adapter ESD test device, including: a bottom plate; a positioning mold, which is fixedly arranged on the top of the bottom plate and is used to place the adapter; guide rails, which are symmetrically arranged on both sides of the bottom plate; an electrostatic gun, which is used to perform ESD testing on the adapter. A support plate is arranged below the electrostatic gun, and the support plate is slidably connected to the guide rails; the electrostatic gun can sequentially pass through the input wire, the outer shell, the LED lamp and the output wire of the adapter under the guiding action of the guide rails; this device guides and moves the electrostatic gun through the guide rails, and sequentially passes through all the test points of the adapter, which can avoid missing test points to a certain extent, and through the guide rails, the moving height of the electrostatic gun can be guaranteed to be stable, ensuring the test effect;

[0004] However, the above solution still has the following defects:

[0005] In the above solution, the shape of the guide rails matches the curved path formed by the input wire, the outer shell, the LED lamp and the output wire of the power adapter. This makes the support plate and the staff's hand move horizontally along the shape of the guide rails when the staff holds the electrostatic gun and moves longitudinally for testing at the above points, making it inconvenient for the staff to apply longitudinal force when pushing the support plate and the electrostatic gun, and when the height of the electrostatic gun is lifted, the heights of the two guide rails cannot be adjusted synchronously, so there may be a certain height difference between the two guide rails, resulting in greater friction when the support plate moves and being difficult to operate. Content of the Utility Model

[0006] The purpose of the utility model is to provide an ESD test inspection device to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An ESD test inspection device includes a bottom plate, on which a positioning mold is installed. Two bases are vertically movably arranged on the top of the bottom plate through an adjusting mechanism. Each base surface is provided with a chute, and the shape of the chute matches the curved path formed by the input wire, outer shell, LED lamp and output wire of the power adapter. Sliders are horizontally movably arranged on the sides of the two bases. A support plate is movably arranged on the tops of the two sliders through a support mechanism. A guiding member is arranged at the bottom of the support plate, and the guiding member is slidably arranged inside the chute. A through groove is arranged at the top of the support plate, and a clamping plate for installing an electrostatic gun is fixed on the top of the support plate.

[0009] Preferably, the support mechanism includes a guide rod, a connecting arm and a spring. The guide rod is vertically fixed between the two sliders. One end of the connecting arm is fixed on the surface of the support plate, and the other end of the connecting arm is slidably arranged on the surface of the guide rod. The spring is fixed between the connecting arm and the slider, and the spring is sleeved on the surface of the guide rod.

The top end of the limiting rod is fixed to the bottom of the base, and the limiting rod is slidably arranged on the surface of the bottom plate. The bracket is arranged below the bottom plate, and the bottom end of the limiting rod is fixed to the top of the bracket. The threaded rod is rotatably arranged at the bottom of the bottom plate, and the end of the threaded rod penetrates and is threadedly connected to the surface of the bracket. The handle is fixed to the end of the threaded rod.

[0011] Preferably, the guiding member is set as a roller. The roller is rotatably arranged at the bottom of the support plate, and the side wall of the roller just abuts against the inner wall of the chute.

The slider can move horizontally in the longitudinal direction between two bases. At this time, through the arrangement of the guiding member and the chute, the shelf board can be driven to move horizontally in the transverse direction. Due to the special shape of the chute, the movement path of the electrostatic gun can match the curved path formed by the input wire, the outer shell, the LED lamp and the output wire of the power adapter.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5, this utility model provides an ESD test inspection device, including a bottom plate 1. A positioning mold 2 is installed on the bottom plate 1, and the positioning mold 2 is fixedly installed on the surface of the bottom plate 1 by screws. A base 3 is fixedly installed on the top of the limiting rod 12 by screws. Two bases 3 are vertically movably arranged on the top of the bottom plate 1 through an adjusting mechanism. A chute 4 is arranged on the surface of each base 3, and the shape of the chute 4 matches the curved path formed by the input wire, the outer shell, the LED lamp and the output wire of the power adapter. Sliders 5 are horizontally movably arranged on the sides of the two bases 3. A support plate 6 is movably arranged on the tops of the two sliders 5 through a support mechanism. A guide member is arranged at the bottom of the support plate 6, and the guide member is slidably arranged inside the chute 4. A through groove 7 is arranged on the top of the support plate 6, and a clamping plate 8 for installing an electrostatic gun is fixed on the top of the support plate 6. The guide member is set as a roller 16, and the roller 16 is rotatably arranged at the bottom of the support plate 6, and the side wall of the roller 16 just abuts against the inner wall of the chute 4. The support mechanism includes a guide rod 9, a connecting arm 10 and a spring 11. The guide rod 9 is vertically fixed between the two sliders 5. One end of the connecting arm 10 is fixed on the surface of the support plate 6, and the other end of the connecting arm 10 is slidably arranged on the surface of the guide rod 9. The spring 11 is fixed between the connecting arm 10 and the slider 5, and the spring 11 is sleeved on the surface of the guide rod 9.

[0026] Please refer to Figure 1 , 2 , 3 and 4. First, place the power adapter on the positioning mold 2, and then push the guide rod 9. At this time, the guide rod 9 can drive the two sliders 5 to perform longitudinal horizontal movement (set as the X-axis direction) on the sides of the base 3. During this process, the guide rod 9 can drive the support plate 6 to move synchronously through the connecting arm 10. Since the connecting arm 10 is slidably arranged on the guide rod 9, the roller 16 at the bottom of the support plate 6 slides inside the chute 4, and the shape of the chute 4 matches the curved path formed by the input wire, the outer shell, the LED lamp and the output wire of the power adapter. This enables the chute 4 to guide the support plate 6 in the Y-axis direction through the slider 5, so that the support plate 6 can drive the electrostatic gun to move along a specific trajectory, cooperating with the continuously moving slider 5, so that the electrostatic gun can test all points of the power adapter. Not only can all test points be avoided, but when the staff pushes the guide rod 9, the guide rod 9 only moves in the X-axis direction. Therefore, it is convenient for the staff to apply force to the guide rod 9 in the X-axis direction.

[0027] It should be noted that since the spring 11 is fixed between the connecting arm 10 and the slider 5, no matter which direction the connecting arm 10 moves, the spring 11 will be deformed (elongated or compressed). At this time, the elastic force of the spring 11 can pull the connecting arm 10 with a tendency to reset, thereby increasing the static friction force between the roller 16 and one of the side walls of the chute 4. This increases the resistance when the staff pushes the guide rod 9, so as to facilitate the staff to control the force of pushing the guide rod 9 and adjust the positioning between the electrostatic gun and the measurement point.

[0028] A T-shaped track 17 is fixedly arranged on the side surface of the base 3, and a T-shaped limiting groove 18 is arranged on the side surface of the slider 5. The slider 5 is slidably arranged on the surface of the T-shaped track 17 through the T-shaped limiting groove 18.

[0029] Please refer to Figure 3 and 4 , the slider 5 can slide on the side surface of the base 3 through the cooperation of the T-shaped limiting groove 18 and the T-shaped track 17, and the T-shaped limiting groove 18 and the T-shaped track 17 can also limit the slider 5 in the vertical direction to prevent the slider 5 from detaching from the side surface of the base 3.

[0030] It should be noted that in this embodiment, a detachable connection structure fixed by screws is provided between the base 3 and the limiting rod 12, the positioning die 2 and the bottom plate 1. This enables the replacement of the chute 4 and the positioning die 2 according to different specifications of the power adapter, so as to adapt to different specifications of the power adapter for ESD testing.

[0031] The adjusting mechanism includes a limiting rod 12, a threaded rod 13, a handle 14 and a bracket 15. The top end of the limiting rod 12 is fixed to the bottom of the base 3. The limiting rod 12 is slidably arranged on the surface of the bottom plate 1. The bracket 15 is arranged below the bottom plate 1. The bottom end of the limiting rod 12 is fixed to the top of the bracket 15. The threaded rod 13 is rotatably arranged at the bottom of the bottom plate 1. The end of the threaded rod 13 penetrates and is threadedly connected to the surface of the bracket 15. The handle 14 is fixed to the end of the threaded rod 13. A support leg 19 is fixedly installed at the bottom of the bottom plate 1, and an anti-slip pad 20 is adhered to the bottom of the support leg 19.

[0032] Please refer to Figure 2, the bottom plate 1 can be stably placed on a horizontal plane through the support legs 19, and the anti-slip pads 20 can increase the overall stability of the bottom plate 1. When height adjustment is required, the staff can directly rotate the handle 14 under the bottom plate 1 to drive the threaded rod 13 to rotate. When the threaded rod 13 rotates, it can drive the support 15 to adjust the height, so that the support 15 can drive the base 3 to move through the limit rod 12. Since the support 15 is connected to the bottoms of the four limit rods 12, the support 15 can drive the four limit rods 12 to move vertically at the same time, so that the two bases 3 can move vertically synchronously, so that the two bases 3 always remain at the same height, preventing the friction between the rollers 16 and the chute 4 from being too large due to the height difference and making it difficult to push the guide rod 9 to drive the whole action of the rack plate 6.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
