TECHNICAL FIELD
[0001] The present application relates to the technical field of electrostatic discharge testing, for example to an electrostatic discharge testing device. BACKGROUND
[0002] Electrostatic discharge (ESD) is the main factor causing most electronic components or electronic systems to be damaged by electrical overstress (EOS). This damage can cause semiconductor components and computer systems to malfunction or be permanently damaged, thereby affecting the circuit function of integrated circuits (ICs) and causing electronic products to malfunction. Therefore, electronic products currently seen on the market must pass electrostatic discharge testing in electromagnetic compatibility testing before they can be sold. Most electrostatic discharge tests are currently performed manually by holding a static gun. It is difficult to ensure that the discharge head of the static gun is perpendicular to the test plane, and in repeated tests, the angle and position of the previous test cannot be reproduced, which can affect the accuracy of the test results.
[0003] A related art electrostatic discharge testing system includes a longitudinal adjusting device, a transverse adjusting device, a vertical adjusting device, and a fixing device. The longitudinal adjusting device is used to drive the fixing device to move longitudinally in the horizontal direction. The transverse adjusting device is used to drive the fixing device to move transversely in the horizontal direction. The vertical adjusting device is used to drive the fixing device to move vertically. The fixing device is used to install a static gun. The vertical adjusting device includes a vertical stepper motor, a vertical synchronous belt mechanism, a vertical slide rail, and a vertical slide block. The drive pulley of the vertical synchronous belt mechanism is in transmission connection with the motor shaft of the vertical stepper motor. The vertical slide block is fixed to the synchronous belt of the vertical synchronous belt mechanism and is slidably arranged on the vertical slide rail. The fixing device is fixed to the vertical slide block. The synchronous belt of the vertical synchronous belt mechanism has high movement displacement accuracy, so that the vertical slide block has high repeat positioning accuracy on the vertical slide rail, and the vertical synchronous belt mechanism can be better applied to the continuous reciprocating movement of the static gun in the vertical direction.

[0040] Combine Figure 1-7 As shown, an embodiment of the present disclosure provides an electrostatic discharge testing device, including a track 100, a moving device 200, a trigger trigger 300 and a static elimination component, wherein the track 100 is used to be set on the surface to be tested 700; the moving device 200 is slidably connected to the track 100, and the moving device 200 is provided with a transmission belt; the trigger trigger 300 is set on the transmission belt and moves along the transmission belt in a first direction, and the first direction is perpendicular to the surface to be tested 700; the static elimination component is set on the transmission belt and moves along the transmission belt in a second direction, and the second direction is parallel to the surface to be tested 700; wherein, the electrostatic gun 500 is set on the trigger trigger 300 and moves along the transmission belt following the trigger trigger 300. When the electrostatic gun 500 follows the trigger trigger 300 to move along the transmission belt toward the surface to be tested 700, it drives the static elimination component along the transmission belt away from the surface to be tested 700. After the test is completed, the trigger trigger 300 is reset, and the static elimination component is reset to erase the charge on the surface to be tested 700.
[0041] The electrostatic discharge testing device provided by the embodiment of the present disclosure includes a track 100 and a moving device 200, the track 100 is used to be set on the surface to be tested 700, and the moving device 200 is slidably connected to the track 100. A transmission belt is provided on the moving device 200, and a trigger trigger 300 is provided on the transmission belt, and the trigger trigger 300 can move in a first direction following the transmission belt. The first direction is perpendicular to the surface to be tested 700. When in use, the electrostatic gun 500 is set on the trigger trigger 300 and moves along the transmission belt following the trigger trigger 300, which can effectively ensure that the electrostatic gun head maintains a vertical angle when approaching the surface to be tested 700, as well as the accuracy of the positioning of the electrostatic gun head, and facilitates the reproduction of test results. The electrostatic discharge testing device provided by the embodiment of the present disclosure has a simple structure, which can effectively reduce the volume and weight of the device, facilitate movement and use, and effectively reduce the failure rate.
[0042] A static elimination component is also provided on the transmission belt, and the static elimination component can move along the transmission belt in a second direction, and the second direction is parallel to the surface to be tested 700. When the static gun 500 follows the trigger trigger 300 and moves along the transmission belt toward the surface to be tested 700, it drives the static elimination component away from the surface to be tested 700 along the transmission belt. After the test is completed, the trigger 510 is triggered to reset, and then the static elimination component is reset to erase the residual static electricity on the surface to be tested 700. By setting the static elimination component to automatically erase the residual static electricity on the surface to be tested 700 after each test is completed, the safety of the product to be tested can be effectively guaranteed. Moreover, instead of manually clearing the residual static electricity, such a setting form can effectively improve the convenience during testing, and thus can effectively improve the user experience.
[0043] Optionally, the track 100 includes a track body, a fixing member 130 and a leveling device, the track body including a first track bar 110 and a second track bar 120 that are arranged opposite to each other and parallel to each other; the fixing member 130 is rotatably arranged at the first end of the track body so that the track body can be rotated and adjusted with the fixing member 130 as the center; the leveling device is arranged at the second end of the track body, for adjusting the parallelism between the track body and the surface to be tested 700, so that the electrostatic gun 500 is perpendicular to the surface to be tested 700.
[0044] The mobile device 200 can move linearly along the first and second track bars 110, 120 of the track body. A fixing member 130 is provided at the first end of the track body, and the fixing member 130 can rotate relative to the track body. The track body can then be rotated and adjusted around the fixing member 130. This arrangement effectively expands the area of the test surface 700 covered by the track 100, providing more testing area for the electrostatic gun 500, thereby effectively improving the accuracy of the test results.
[0045] A leveling device is provided at the second end of the track body, and the parallelism between the track body and the surface to be tested 700 is adjusted by the leveling device. This can effectively ensure that the gun head of the electrostatic gun 500 maintains a vertical angle when approaching the surface to be tested 700, so as to meet the standard requirements of the electrostatic discharge test, thereby ensuring the validity of the test results.
[0046] In the embodiment of the present disclosure, the fixing member 130 is used to fix to the surface to be tested 700, for example, using a suction cup, a clamp, etc., as long as it can be fixed to the surface to be tested 700 and easily disassembled, there is no specific limitation on this.
[0047] Optionally, the moving device 200 includes a first frame and a second frame, the first frame is slidably connected to the first track bar 110, and the first frame is provided with a first transmission belt 222; the second frame is slidably connected to the second track bar 120, and the second frame is provided with a second transmission belt 242, and the second frame and the first frame jointly define a horizontal moving space and a vertical moving space; wherein, the trigger trigger 300 is respectively provided on the first transmission belt 222 and the second transmission belt 242 at both ends of the vertical moving space, and the static elimination component is respectively provided on the second transmission belt 242 at both ends of the horizontal moving space.
[0048] By providing two frames, a first frame and a second frame, the first frame is slidably connected to the first track bar 110, and the second frame is slidably connected to the second track bar 120. Thus, the first frame and the second frame together define a movement space, that is, the trigger member 300 and the static elimination assembly move between the two frames. The second frame and the first frame together define a horizontal movement space and a vertical movement space. The horizontal movement space here refers to the movement space plane parallel to the test surface 700, and the vertical movement space refers to the movement space plane perpendicular to the test surface 700.
[0049] A first transmission belt 222 is mounted on the first frame, and a second transmission belt 242 is mounted on the second frame. The trigger member 300 is mounted on the first transmission belt 222 at either end of the vertical movement space, while the static elimination component is mounted on the second transmission belt 242 at either end of the horizontal movement space. This arrangement ensures the synchronization of the movement of the trigger member 300 and the static elimination component. Furthermore, upon completion of the test, the trigger member 300 is reset, and the static elimination component resets to eliminate any residual static electricity on the test surface 700.
[0050] Optionally, the first frame includes a first rod 210 and a second rod 220, the first rod 210 is parallel to the first track bar 110 and is slidably connected to the first track bar 110; the first end of the second rod 220 is connected to the first end of the first rod 210, and the second rod 220 is perpendicular to the first rod 210; the second frame includes a third rod 230 and a fourth rod 240, the third rod 230 is parallel to the second track bar 120 and is slidably connected to the second track bar 120; the first end of the fourth rod 240 is connected to the first end of the third rod 230, and the fourth rod 240 is perpendicular to the first rod 210. The first rod 210 and the third rod 230 are perpendicular to each other; wherein, the second end of the first rod 210 and the first and second ends of the second rod 220 are each provided with a first rotating wheel 221, and the first transmission belt 222 is connected to the three first rotating wheels 221; the second end of the third rod 230 and the first and second ends of the fourth rod 240 are each provided with a second rotating wheel 241, and the second transmission belt 242 is connected to the three second rotating wheels 241; the first rod 210 and the third rod 230 jointly define a horizontal moving space, and the second rod 220 and the fourth rod 240 jointly define a vertical moving space.
[0051] The second end of the first rod 210 and the first and second ends of the second rod 220 are each provided with a first rotating wheel 221. A first transmission belt 222 is connected to the three first rotating wheels 221. Thus, the first transmission belt 222 forms a right triangle. Correspondingly, the second transmission belt 242 also forms a right triangle. The trigger member 300 is located on a right-angled face of the right triangle that is perpendicular to the surface to be tested 700, and the static elimination component is located on a right-angled face of the right triangle that is parallel to the surface to be tested 700.
[0052] Combine Figure 1 and Figure 2 As shown, the tester holds the static gun 500 and places it on the trigger activator 300. The tester then pushes the trigger 510, pressing it and causing the static gun tip to begin charging. Driven by the first and second transmission belts 222 and 242, the static gun 500 follows the trigger activator 300 in the vertical travel space toward the test surface 700. The static elimination component moves from the right-angled face of the right triangle parallel to the test surface 700 toward the inclined face of the right triangle (this is the first operating state). This continues until the static gun 500 is in position and begins discharging (this is the second operating state). After discharging is complete, the static gun 500 moves in the opposite direction along the vertical travel space. The first and second transmission belts 222 and 242 drive in opposite directions, resetting the trigger activator 300. The static elimination component resets and eliminates any residual static electricity on the test surface 700. The static gun 500 is then removed, releasing the trigger 510. This completes one test. The tester can perform multiple tests as needed.
[0053] By adopting such a setting form, the structure is simple, the electrostatic discharge testing device is convenient to move and use, the failure rate of the device can be effectively reduced, and the convenience of testing can be effectively improved, and the use experience of testers is improved.
[0054] In addition, the charging distance of the electrostatic gun 500 can be fixed, and the test precision can be effectively avoided due to the additional electromagnetic interference of the electrostatic gun 500 itself when charging at a short distance.
[0055] Optionally, the trigger member 300 includes a fixed plate 310, a clamping portion 320, and a trigger portion 330. Both ends of the fixed plate 310 are arranged on the first transmission belt 222 and the second transmission belt 242 corresponding to the vertical movement space. The clamping portion 320 is arranged on the top end surface of the fixed plate 310, and the clamping portion 320 and the fixed plate 310 form a first stepped structure for placing the electrostatic gun 500. The trigger portion 330 is arranged on the top end surface of the clamping portion 320, and the trigger portion 330 and the clamping portion 320 form a second stepped structure. When the electrostatic gun 500 is placed in the clamping portion 320, the trigger 510 of the electrostatic gun 500 abuts against the trigger portion 330.
[0056] When the electrostatic gun 500 is placed, the corner formed by the trigger 510 and the handle is clamped in the clamping portion 320, the tail end of the handle abuts against the fixed plate 310, and the trigger 510 abuts against the trigger portion 330.
[0057] By adopting such a setting form, the stability of the electrostatic gun 500 when placed in the trigger member 300 can be effectively ensured, and the electrostatic gun 500 is effectively avoided to be affected, and the perpendicularity of the gun head of the electrostatic gun 500 and the surface to be tested 700 is affected.
[0058] Optionally, the static electricity removing assembly includes a static electricity removing brush 400 and a grounding assembly (not shown). The static electricity removing brush 400 includes a brush body and bristles. Both ends of the brush body are arranged on the first transmission belt 222 and the second transmission belt 242 corresponding to the horizontal movement space. One end of the bristles is connected to the brush body, and the other end extends to the surface to be tested 700. One end of the grounding assembly is connected to the static electricity removing brush 400, and the other end is used for grounding.
[0059] When the grounded static electricity removing brush 400 approaches the surface to be tested 700 with residual static electricity, an unequal strong electric field is formed between the two, and the nearby gas molecules are ionized to generate positive and negative ion pairs. The charged charges on the surface to be tested 700 attract opposite polarity ionized ions and neutralize, thereby achieving the elimination of residual static electricity.
[0060] By adopting such a setting form, the effect of eliminating static electricity can be effectively improved.
[0061] Optionally, the moving device 200 also includes a first return spring 250 and a second return spring 260, one end of the first return spring 250 is connected to the second end of the second rod body 220, and the other end is connected to the first transmission belt 222; the second return spring 260 corresponds to the first return spring 250, one end of which is connected to the second end of the fourth rod body 240, and the other end is connected to the second transmission belt 242; wherein, when the electrostatic gun 500 follows the trigger trigger 300 and moves along the first transmission belt 222 and the second transmission belt 242 toward the surface to be tested 700, the first return spring 250 and the second return spring 260 are stretched, and the static elimination component moves away from the surface to be tested 700 along the first transmission belt 222 and the second transmission belt 242. When the test is completed, the first return spring 250 and the second return spring 260 contract and reset, respectively driving the first transmission belt 222 and the second transmission belt 242 to move, thereby driving the trigger trigger 300 to reset, and the static elimination component resets to erase the charge on the surface to be tested 700.
[0062] A first return spring 250 and a second return spring 260 are respectively provided on the first frame and the second frame. The return springs assist in resetting the trigger member 300 and the static elimination component. The structure is simple and easy to manufacture and install.
[0063] Optionally, the mobile device 200 also includes a connecting rod 270, the two ends of which are respectively connected to the first end of the second rod body 220 and the first end of the fourth rod body 240; the electrostatic discharge testing device also includes a laser positioning device 600, which is arranged on the connecting rod 270 to assist in positioning the electrostatic gun 500 and leveling the leveling device.
[0064] By providing the laser positioning device 600 to assist the positioning of the electrostatic gun 500 and the leveling of the leveling device, the accuracy of positioning and the parallelism of leveling can be effectively improved, thereby improving the validity and accuracy of the test results.
[0065] Optionally, the laser positioning device 600 includes a first laser and a second laser, the first laser is arranged on the connecting rod 270, the first laser is perpendicular to the surface to be tested 700, and is used to project a projection onto the surface to be tested 700 to assist in the leveling of the leveling device; the second laser is arranged on the connecting rod 270, the second laser is located on the side of the first laser facing the second end of the first rod body 210, and forms a first preset angle with the first laser, the second laser emits laser light toward the surface to be tested 700 to assist in the positioning of the electrostatic gun 500.
[0066] The first laser is perpendicular to the surface to be tested 700 and is used to project a projection onto the surface to be tested 700 to assist in leveling the leveling device. Specifically, the first laser projects a circular projection. When the projection forms a perfect circle on the surface to be tested 700, the track 100 is parallel to the surface to be tested 700, meaning that the electrostatic gun tip can maintain a perpendicular angle to the surface to be tested 700.
[0067] Since the height between the electrostatic gun 500 and the surface to be tested 700 is greater than the height between the track 100 and the surface to be tested 700, and both the first laser and the second laser are arranged on the connecting rod 270. Therefore, the second laser should be located on the side of the first laser facing the second end of the first rod body 210, and form a first preset angle with the first laser. In this way, it is easier to assist the positioning of the electrostatic gun 500 tip. Specifically, the second laser emits laser light toward the surface to be tested 700, thereby forming an indication point on the surface to be tested 700, which is the discharge point of the electrostatic gun 500 tip.
[0068] This arrangement has a simple structure and is easy to implement. It can also effectively improve the accuracy of positioning and the parallelism of leveling, thereby improving the effectiveness and accuracy of the test results.
[0069] Optionally, a screw hole is provided at the second end of the track body; the leveling device is a leveling bolt 140, comprising a head and a screw, the screw being passed through the screw hole from the track body toward the side of the test surface 700, and the side of the head facing the test surface 700 is flat.
[0070] When the electrostatic discharge testing device is set on the surface to be tested 700, the fixing member 130 on the first end of the track body is fixed to the surface to be tested 700, and the head of the leveling bolt 140 is against the surface to be tested 700. According to the length of the screw hole that is screwed out from the track body toward the side of the surface to be tested 700 by the first laser adjustment screw, the parallelism between the track body and the surface to be tested 700 is adjusted.
[0071] Such a setting form has a simple structure and is easy to operate.
[0072] Optionally, the length of the head of the leveling bolt 140 is equal to the width of the rail body.
[0073] In this way, the contact area between the head of the leveling bolt 140 and the test surface 700 is increased, thereby effectively improving the stability of the track 100 when it is set on the test surface, and preventing the track 100 from shaking during the test and affecting the validity of the test results.
[0074] Optionally, the transmission belt, the track 100 , the first frame, the second frame and the trigger member 300 are all made of non-metallic materials.
[0075] Therefore, the electromagnetic interference generated to the electronic product during the testing can be effectively reduced, and the testing precision is improved.
