[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0022] In this embodiment, if Figure 1 As shown, the clamping device of the electrostatic generator 5 includes a support seat 41, a clamping component 42 and an elastic component 43. The support seat 41 is suitable for being connected to a driving component so as to drive the support seat 41 to move through the driving component; the clamping component 42 is arranged on the support seat 41 and is movable relative to the support seat 41, and the clamping component 42 is used to clamp the electrostatic generator 5; in the moving direction of the clamping component 42, the elastic component 43 has a first end and a second end, the first end of the elastic component 43 is connected to the support seat 41, and the second end of the elastic component 43 is connected to the clamping component 42.
[0023] Specifically, the support seat 41 is connected to the driving member through a connecting member, and the connecting member can be a bolt. The specific connection method between the connecting member, the driving member, and the support seat 41 can be set as needed and will not be described in detail here. For example, the driving member can be a mechanical arm, and the mechanical arm drives the clamping member 42 to move through the support seat 41, and the clamping member 42 drives the electrostatic generator 5 to move, so that the electrostatic discharge test can be performed on the product under test.
[0024] For example, the elastic member 43 is a spring. Of course, the elastic member 43 can also be configured in other forms, which are not limited here.
[0025] For example, the clamping component 42 includes a fixed plate and a clamping piece, and the fixed plate is arranged on the support seat 41. The clamping piece includes a driving unit and a clamping claw, and the driving unit is arranged on the fixed plate, and the clamping claw is connected to the driving unit, and the driving unit drives the clamping claw to clamp or release the gun head of the electrostatic generator 5. The driving unit can be a clamping claw cylinder, and the connection mode of the clamping claw and the clamping claw cylinder is a conventional prior art, which is not described in detail here. The clamping claw is provided with two, and the two clamping claws are respectively connected to the output end of the clamping claw cylinder, and the two opposite sides of the two clamping claws are provided with anti-skid pads. By arranging the anti-skid pads, the friction between the clamping claw and the electrostatic generator 5 can be increased, and the damage caused by the extrusion of the electrostatic generator 5 can be reduced.
[0026] It can be understood that by arranging the clamping component 42 on the support base 41 and being movable relative to the support base 41, when the electrostatic generator 5 and the product under test come into contact, buffering can be performed by the elastic member 43, thereby reducing damage to the electrostatic generator 5 and the product under test, and while clamping the electrostatic generator 5, the function of protecting the electrostatic generator 5 can also be satisfied.
[0027] In this embodiment, the clamping device of the electrostatic generator 5 further includes a connecting block, which is connected to the clamping member 42, and has a mounting hole, in which the second end of the elastic member 43 is connected. For example, the connecting block is a T-shaped block, the mounting hole is located in the middle of the connecting block, and both ends of the connecting block are provided with fixing holes, so that the connecting block can be fixed to the clamping member 42 by screws passing through the fixing holes. By providing the connecting block, an installation space can be provided for the elastic member 43, which is convenient for the installation of the elastic member 43, and the elastic member 43 can be guided through the mounting hole.
[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the clamping device of the electrostatic generator 5 further includes a pressure sensor 1, which is disposed on the support seat 41, and the pressure sensor 1 is located between the first end of the elastic member 43 and the support seat 41.
[0029] For example, the model of the pressure sensor 18 may be NS-TH17A-10kg. Of course, the pressure sensor 18 may also be set to other models, which is not limited here.
[0030] It can be understood that by setting up the pressure sensor 1, the pressure information between the electrostatic generator 5 and the product under test can be obtained, so that the position of the electrostatic generator 5 can be adjusted in time according to the pressure information between the electrostatic generator 5 and the product under test. When the pressure between the electrostatic generator 5 and the product under test is greater than the preset value, the electrostatic generator 5 can be moved away from the product under test to avoid damage to the electrostatic generator 5 and the product under test.
[0031] In this embodiment, if Figure 1 and Figure 2 As shown, the support seat 41 includes a support plate 411 and two side plates 412, the pressure sensor 1 is arranged on the support plate 411, and the support plate 411 is suitable for being connected to the driving member; the two side plates 412 are spaced apart on both sides of the support plate 411, the clamping part 42 is located between the two side plates 412, and the clamping part 42 is movable relative to the side plates 412.
[0032] Specifically, the support plate 411 and the two side plates 412 form a U shape, and the clamping component 42 is located in a space formed between the support plate 411 and the two side plates 412 .
[0033] It is understandable that by arranging the clamping component 42 between the two side plates 412 and being movable relative to the side plates 412 , both sides of the clamping component 42 can be supported by the side plates 412 , which is conducive to the stable movement of the clamping component 42 relative to the side plates 412 .
[0034] In this embodiment, if Figure 1 and Figure 2 As shown, the support seat 41 further includes a guide rail 413 and a slider 414 . Two guide rails 413 are arranged in parallel and spaced apart between the two side plates 412 . A slider 414 is arranged on each guide rail 413 , and the clamping component 42 is arranged on the slider 414 .
[0035] It can be understood that, through the cooperation of the guide rail 413 and the slider 414, the friction force when the clamping component 42 moves can be reduced, so that the clamping component 42 can move more smoothly and can more accurately feedback the pressure exerted on the electrostatic generator 5 when testing the product under test, thereby improving the protection effect of the electrostatic generator 5.
[0036] In this embodiment, the guide rail 413 is cylindrical, the slider 414 has a connecting hole, and the slider 414 is disposed outside the guide rail 413 .
[0037] It is understandable that the guide rail 413 adopts a cylindrical guide rail 413, which can enable the clamping component 42 to maintain high precision and higher stability during the movement.
[0038] In this embodiment, the clamping device of the electrostatic generator 5 also includes a limit block. The limit block is set at one end of the side plate 412 away from the support plate 411. One end of the guide rail 413 is connected to the support plate 411, and the other end of the guide rail 413 is connected to the limit block.
[0039] It is understandable that by providing the limit block, the installation of the guide rail 413 can be facilitated, and the slider 414 can also be limited by the limit block to prevent the slider from escaping from the guide rail 413.
[0040] In this embodiment, the electrostatic discharge testing device includes a driving member, an electrostatic generator 5 and the above-mentioned electrostatic generator 5 clamping device, the support base 41 is connected to the driving member, the driving member is used to drive the support base 41 to move, and the electrostatic generator 5 is arranged on the clamping member 42.
[0041] It is understandable that the electrostatic generator 5 is fixed by the clamping component 42, and the driving member drives the clamping component 42 to move through the support base 41, thereby driving the electrostatic generator 5 to move through the clamping component 42 to test different parts of the tested product.
[0042] In this embodiment, if Figure 1 and Figure 2As shown, the electrostatic discharge testing device further includes a laser distance measuring sensor 2 , and the laser distance measuring sensor 2 is disposed on a supporting seat 41 .
[0043] Specifically, at least one of the two side plates 412 has an extension portion 7, and the laser ranging sensor 2 is connected to the extension portion 7, which is located on the side of the side plate 412 away from the support plate 411. The specific model of the laser ranging sensor 2 can be selected as needed and is not limited here.
[0044] It should be noted that when the discharge method applied by the gun head of the electrostatic generator 5 to the product under test is air discharge, the distance is measured by the laser ranging sensor 2. According to the distance measurement information of the laser ranging sensor 2, a certain distance can be maintained between the discharge tip of the electrostatic discharge generator and the product under test, thereby completing the air discharge test.
[0045] In this embodiment, if Figure 1 and Figure 2 As shown, two laser distance measuring sensors 2 are provided, and the two laser distance measuring sensors 2 are arranged in parallel and at intervals on the support base 41 .
[0046] Specifically, two laser distance measuring sensors 2 are arranged at intervals in the extension part 7. The direction of electrostatic discharge of the gun head of the electrostatic generator 5 is perpendicular to the product to be measured. The product to be measured is placed vertically. By setting two laser distance measuring sensors 2 for distance measurement, the mechanical arm drives the gun head of the electrostatic discharger to discharge electrostatically in the horizontal direction, thereby improving the accuracy of positioning.
[0047] In this embodiment, if Figure 1 and Figure 2 As shown, the electrostatic discharge testing device further includes a visual camera 6 , which is disposed on a supporting seat 41 .
[0048] Specifically, the visual camera 6 is a binocular visual camera 6, which uses two cameras to capture images of the product under test from different angles, and senses the three-dimensional spatial position of the product under test by calculating the parallax between these images. The working principle of the binocular visual camera 6 is conventional prior art and will not be described in detail here. The visual camera 6 can be arranged on the extension part 7, and the visual camera 6 and the laser ranging sensor 2 are respectively located on both sides of the extension part 7, which can make the overall structure more compact. Of course, the visual camera 6 and the laser ranging sensor 2 can also be located on different side panels 412, which is not limited here.
[0049] The visual camera 6 is used to collect the appearance image information of the product under test, and based on the collected image information, a coordinate system of the robot arm and the product under test is established, and the relative position information between the product under test and the robot arm is recorded and used as the coordinates of the robot arm's activities. At the same time, the measured area of the product under test is processed into plane coordinates to facilitate the operator to mark the measured points, thereby facilitating the control of the robot arm to drive the electrostatic generator 5 to move.
[0050] In this embodiment, if Figure 1 and Figure 2 As shown, the electrostatic discharge testing device further includes a protective cover 3 , which is arranged outside the visual camera 6 .
[0051] For example, the protective cover 3 may be cylindrical, specifically a square cylinder or a cylindrical shape, etc., and the visual camera 6 is disposed in the protective cover 3. The shape of the protective cover 3 is not intended to limit the present invention.
[0052] It can be understood that by setting a protective cover 3 on the outside of the visual camera 6, the visual camera 6 can be protected to reduce damage to the visual camera 6 in the event of a collision. At the same time, the protective cover 3 also has a certain dust-proof effect, which reduces dust deposition on the lens of the visual camera 6 and affects the shooting effect of the visual camera 6.
