Description

Technical Field

[0001] This application relates to the technical field of electrostatic discharge testing, and in particular to an electrostatic protection testing system based on a multi-axis robotic arm. Background Technology

[0002] With the rapid development of technology, electronic devices have become an indispensable part of people's lives. However, during the use of electronic devices, electrostatic discharge (ESD) can cause damage to electronic components, leading to malfunctions and other problems. Therefore, electrostatic discharge (ESD) protection testing is a crucial step in ensuring product quality and reliability during the manufacturing process of electronic devices.

[0003] Currently, ESD testing of electronic devices (such as mobile phones and tablets) mainly involves placing the device on a test bench, with workers using electrostatic discharge guns to discharge at predetermined points, and then checking whether the screen and other parts of the electronic device are functioning properly. However, this manual inspection method easily causes arm and visual fatigue for workers, affecting the accuracy and efficiency of the test results. Although related technologies provide automated equipment to reduce manual intervention, different specifications of gun tips are required during the testing process to meet the testing needs of different locations on the electronic device. Manually changing these tips affects the testing efficiency. Therefore, an electrostatic discharge testing system is needed to meet the testing needs of different gun tips and improve testing efficiency. Utility Model Content

[0004] To improve the detection efficiency of electrostatic discharge testing for electronic devices, this application provides an electrostatic protection testing system based on a multi-axis robotic arm.

[0005] This application provides an electrostatic discharge (ESD) protection testing system based on a multi-axis robotic arm, which adopts the following technical solution:

[0006] An electrostatic discharge protection testing system based on a multi-axis robotic arm includes a worktable, a fixing device, a discharge device, a gripping device, a testing device, and a gun head replacement device.

[0007] Both the fixing device and the gripping device are mounted on the worktable; when the gripping device picks up the electronic device and moves it to the fixing device, the fixing device clamps the electronic device.

[0008] The detection device is used to detect electronic equipment;

[0009] The discharge device includes the electrostatic gun driving assembly and the electrostatic gun, the electrostatic gun driving assembly being disposed on the workbench; the electrostatic gun driving assembly drives the electrostatic gun to move, causing the electrostatic gun to move to the position of the electronic device to discharge;

[0010] The gun head replacement device includes a replacement support frame, a replacement drive component, and multiple gun head placement seats; the replacement support frame is disposed on the workbench, the replacement drive component is disposed on the replacement support frame, and the gun head placement seats are rotatably disposed on the replacement support frame; when the electrostatic gun abuts against the inner wall of the gun head placement seat, the replacement drive component drives the gun head placement seat to rotate, so that the gun head of the electrostatic gun can be removed or installed.

[0011] By adopting the above technical solution, since the gun head of the electrostatic gun is threadedly connected to the body of the electrostatic gun, after the electrostatic gun abuts against the inner wall of the gun head placement seat, the gun head placement seat can rotate to remove or install the gun head of the electrostatic gun, thereby completing the replacement of the gun head of the electrostatic gun and improving the detection efficiency.

[0012] Optionally, the replacement device further includes a replacement detection element, which is disposed on the workbench and is used to monitor the movement of the electrostatic gun into the gun head placement seat.

[0013] By adopting the above technical solution, when the replacement detection component detects that the electrostatic gun has moved into the gun head placement seat, the replacement drive component drives the gun head placement seat to rotate, which further improves the reliability of the replacement device in replacing the gun head of the electrostatic gun.

[0014] Optionally, the replacement support frame includes a first support frame, a second support frame, and a buffer assembly. The first support frame is connected to the worktable; the second support frame is slidably connected to the first support frame; and the buffer assembly is disposed between the first support frame and the second support frame, and the buffer assembly is used to provide cushioning for the second support frame.

[0015] By adopting the above technical solution, when the electrostatic gun abuts against the gun head placement seat, the buffer assembly can provide buffer for the second support frame, thereby reducing the possibility of damage to the electrostatic gun upon contact with the gun head placement seat.

[0016] Optionally, the buffer assembly includes a first buffer rod, a second buffer rod, and a buffer member. One end of the first buffer rod is connected to the second support frame, and the other end passes through the second buffer rod. The buffer member is located inside the second buffer rod, and both ends of the buffer member are connected to the inner walls of the first buffer rod and the second buffer rod, respectively.

[0017] By adopting the above technical solution, when the electrostatic gun abuts against the inner wall of the gun head holder, the buffer is compressed, thereby providing cushioning for the electrostatic gun. Simultaneously, under the elastic force of the buffer, the gun head holder presses tightly against the electrostatic gun, thereby increasing the friction between the gun head holder and the gun head of the electrostatic gun, and improving the reliability during gun head replacement.

[0018] Optionally, the detection device includes a vision detection element and a contact assembly; the contact assembly includes a contact driver and a contact, the contact driver being disposed on the gripping device; the contact driver drives the contact to move, so that the contact detects the touch screen response of the electronic device; the vision detection element is disposed on the gripping device, and the vision detection element is used to monitor the detection process of the electronic device.

[0019] By adopting the above technical solution, the contact driving component can drive the contact to make contact with the screen of the electronic device, thereby realizing the detection of the touch screen response of the electronic device. The vision detection component can monitor the detection process and improve the accuracy of the detection.

[0020] Optionally, the electrostatic gun drive assembly includes a first robotic arm, a connecting frame, an electrostatic gun mounting base, and an elastic element;

[0021] The first robotic arm is connected to the workbench, and the connecting frame is mounted on the first robotic arm; the electrostatic gun mounting base is slidably connected to the connecting frame, and the two ends of the elastic element are respectively connected to the connecting frame and the electrostatic gun mounting base.

[0022] By adopting the above technical solution, the electrostatic gun mounting base is slidably connected to the connecting frame, allowing the electrostatic gun to move adaptively and reducing the possibility of damage when the electrostatic gun comes into contact with electronic equipment. The elastic force of the elastic element can balance the weight of the electrostatic gun and the electrostatic gun mounting base, thereby reducing the pressure of the electrostatic gun on the electronic equipment and further reducing the possibility of damage when the electrostatic gun comes into contact with the electronic equipment.

[0023] Optionally, the electrostatic gun drive assembly further includes a first detection element and a second detection element; the first detection element is connected to the first robotic arm and the connecting frame respectively, and the first detection element is used to detect the pressure of the electrostatic gun; the second detection element is connected to the connecting frame, and the second detection element is used to monitor the distance between the electrostatic gun and the electronic device.

[0024] By adopting the above technical solution, when the electrostatic gun contacts the electronic device, the electronic device provides a supporting force to the electrostatic gun, enabling the first detection element to detect the pressure change. The second detection element can detect the distance between the electrostatic gun and the electronic device. Through the cooperation of the first and second detection elements, it is convenient to control the electrostatic gun to move to a designated position for discharge, thereby improving the reliability of the detection process.

[0025] Optionally, the fixing device includes a fixing drive and a fixing block, the fixing drive being connected to the worktable; the fixing drive drives the fixing block to move, clamping the electronic device.

[0026] By adopting the above technical solution, the fixing drive can drive the fixing block to move, thereby fixing the electronic device and reducing the possibility of the electronic device moving during the detection process.

[0027] Optionally, the testing device further includes a USB testing component, which includes a USB testing driver and a USB testing element. The USB testing driver is connected to the workbench and drives the USB testing element to connect to the electronic device to test the data transmission and charging performance of the electronic device.

[0028] By adopting the above technical solution, the USB detection driver drives the USB detection element to connect to the USB interface of the electronic device, thereby performing detection and improving the accuracy of detection.

[0029] Optionally, a flipping device is also included, which includes a flipping drive and a clamping mechanism. The flipping drive is connected to the worktable, and the clamping mechanism is disposed on the flipping drive. The clamping mechanism is used to clamp electronic devices. The flipping drive drives the clamping mechanism to rotate, thereby flipping the electronic devices.

[0030] By adopting the above technical solution, after the clamping mechanism clamps the electronic device, the flipping drive drives the clamping mechanism to rotate, causing the electronic device to flip, thereby facilitating the detection of different sides of the electronic device and further improving the accuracy of the detection.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By replacing the driving component, the gun head holder is rotated. Since the gun head of the electrostatic gun is threadedly connected to the body of the electrostatic gun, after the electrostatic gun comes into contact with the inner wall of the gun head holder, the gun head holder rotates to remove or install the gun head of the electrostatic gun, thereby completing the replacement of the gun head of the electrostatic gun and improving the detection efficiency.

[0033] 2. When the electrostatic gun comes into contact with the inner wall of the gun head holder, the buffer is compressed, thus providing cushioning for the electrostatic gun. At the same time, under the action of the buffer's elasticity, the gun head holder presses firmly against the electrostatic gun, thereby increasing the friction between the gun head holder and the electrostatic gun and improving the reliability of the gun head replacement process;

[0034] 3. The electrostatic gun mounting base and connecting bracket are slidably connected, allowing the electrostatic gun to move adaptively, reducing the possibility of damage when the electrostatic gun comes into contact with electronic equipment. The elastic force of the elastic element can balance the weight of the electrostatic gun and the electrostatic gun mounting base, thereby reducing the pressure of the electrostatic gun on the electronic equipment, further reducing the possibility of damage when the electrostatic gun comes into contact with the electronic equipment.

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0045] This application discloses an electrostatic discharge (ESD) protection testing system based on a multi-axis robotic arm. For example... Figure 1 As shown, the electrostatic discharge protection testing system includes a workbench 1, a fixing device 2, a discharge device 3, a gripping device 4, a testing device 5, a gun head changing device 6, and a flipping device 7.

[0046] like Figure 1 and Figure 2 As shown, the gripping device 4 includes a second robotic arm 41 and a gripping component 42. The body of the second robotic arm 41 is fixedly connected to the worktable 1, and a connecting seat 43 is fixedly connected to the output end of the second robotic arm 41. The gripping component 42 is fixedly connected to the connecting seat 43. Preferably, the gripping component 42 is a suction cup. The second robotic arm 41 can drive the gripping component 42 to pick up the electronic device from the feeding position of the electronic device and move it to the position of the fixing device 2.

[0047] like Figure 1 and Figure 3As shown, the fixing device 2 includes a fixing drive component 21 and a fixing block 22. A fixing component 11 is installed on the worktable 1. The fixing component 11 includes a first fixing frame 111 and a second fixing frame 112. The first fixing frame 111 is fixedly connected to the worktable 1, and the second fixing frame 112 is bolted to the first fixing frame 111. The body of the fixing drive component 21 is fixedly connected to the second fixing frame 112, and the output end of the fixing drive component 21 is fixedly connected to the fixing block 22. Preferably, the fixing drive component 21 is a pneumatic push rod. In this embodiment, two fixing drive components 21 are installed. On the opposite side of the fixing drive component 21, a corresponding fixing block 22 is installed. The fixing block 22 is bolted to the first fixing frame 111. When the gripping device 4 moves the electronic device to a designated position within the first fixing frame 111 using the gripping component 42, the fixing drive component 21 drives the connected fixing block 22 to move, cooperating with the opposite fixing block 22 to clamp the electronic device, further reducing the possibility of the electronic device moving during the detection process. In addition, the first fixing bracket 111 and the second fixing bracket 112 are connected by bolts, which makes it easy to adjust the position of the fixing drive component 21 according to different specifications of electronic equipment, thus improving the versatility of the device.

[0048] like Figure 1 and Figure 4 As shown, a flipping device 7 is installed on the workbench 1. The flipping device 7 includes a flipping drive 71 and a clamping mechanism 72, wherein the clamping mechanism 72 includes a clamping drive 721 and a clamping block 722. Preferably, the flipping drive 71 is a motor, and the clamping drive 721 is a linear module. The body of the flipping drive 71 is fixedly connected to the workbench 1, the output end of the flipping drive 71 is fixedly connected to the body of the clamping drive 721, and the output end of the clamping drive 721 is fixedly connected to the clamping block 722. In this embodiment, the clamping mechanism 72 is equipped with two clamping blocks 722. The clamping drive 721 can drive the two clamping blocks 722 to move closer and further apart, thereby clamping the electronic device. The second robotic arm 41 drives the gripper 42 to move the electronic device to the flipping device 7. After being clamped by the two clamping blocks 722, the flipping drive 71 drives the electronic device to flip. The gripper 42 can move the flipped electronic device to a designated position, thereby realizing electrostatic protection testing on different sides of the electronic device.

[0049] like Figure 1 and Figure 5As shown, the discharge device 3 includes an electrostatic gun drive assembly 31 and an electrostatic gun 32. Specifically, the electrostatic gun drive assembly 31 includes a first robotic arm 311, a first detection element 312, a connecting frame 313, an electrostatic gun mounting base 314, an elastic element 315, and a second detection element 316. The body of the first robotic arm 311 is fixedly connected to the worktable 1, and its output end is fixedly connected to the first detection element 312. The first detection element 312 is connected to the connecting frame 313. Preferably, the first detection element 312 is a pressure sensor. A slider 3141 is fixedly connected to the electrostatic gun mounting base 314, and a slide rail 3131 is fixedly connected to the connecting frame 313. The slide rail 3131 and the slider 3141 are slidably connected, allowing the electrostatic gun mounting base 314 and the connecting frame 313 to slide relative to each other. One end of the elastic element 315 is mounted on the electrostatic gun mounting base 314, and the other end is mounted on the connecting frame 313. Preferably, the elastic element 315 is a spring.

[0050] It should be noted that after the electrostatic gun 32 is installed on the electrostatic gun mounting base 314, under the action of the gravity of the electrostatic gun 32, the electrostatic gun mounting base 314 slides to the lowest end of the slide rail 3131. At this time, the elastic element 315 is in a stretched state, and the tension of the elastic element 315 can balance the gravity of the electrostatic gun 32 and the electrostatic gun mounting base 314. After the electronic device is fixed in the first fixing frame 111, the first robotic arm 311 drives the electrostatic gun 32 to move to the designated position to discharge the electronic device. When the electrostatic gun 32 needs to contact the electronic device for discharge, the electrostatic gun mounting base 314 is slidably connected to the connecting frame 313, allowing the electrostatic gun 32 to move adaptively, reducing the possibility of damage when the electrostatic gun 32 contacts the electronic device. In addition, the elastic element 315 reduces the pressure of the electrostatic gun 32 on the electronic device, further reducing the possibility of damage to both the electrostatic gun 32 and the electronic device. When the electrostatic gun 32 contacts the electronic device, the electronic device provides support for the electrostatic gun 32, allowing the first detection element 312 to detect the pressure change. The second detection element 316 is fixedly connected to the connecting frame 313. Preferably, the second detection element 316 is a distance sensor, which can detect the distance between the electrostatic gun 32 and the electronic device. By cooperating with the first detection element 312 and the second detection element 316, it is easier to control the electrostatic gun 32 to move to a designated position for discharge, thus improving the reliability of the detection process.

[0051] like Figure 1 and Figure 2As shown, the detection device 5 includes a vision detection element 51 and a contact assembly 52. ​​The vision detection element 51 is mounted on the connecting base 43. In this embodiment, a camera is installed inside the vision detection element 51, enabling it to monitor the detection process of the electronic device. The contact assembly 52 includes a contact driver 521 and a contact 522. The body of the contact driver 521 is fixedly connected to the connecting base 43, and the output end of the contact driver 521 is fixedly connected to the contact 522. Preferably, the contact driver 521 is a pneumatic push rod, and the contact 522 is made of rubber. After the electrostatic gun 32 discharges, the contact driver 521 drives the contact 522 to move and contact the screen of the electronic device. At this time, the vision detection element 51 monitors the screen display of the electronic device to determine whether the touch screen response of the electronic device is normal.

[0052] like Figure 1 , Figure 6 and Figure 7As shown, a gun tip replacement device 6 is also installed on the workbench 1. Specifically, the gun tip replacement device 6 includes a replacement support frame 61, a replacement drive component 62, and a gun tip placement seat 63. The replacement support frame 61 includes a first support frame 611, a second support frame 612, and a buffer assembly 613. The first support frame 611 is fixedly connected to the workbench 1, the second support frame 612 is slidably connected to the first support frame 611, and the gun tip placement seat 63 is rotatably connected to the second support frame 612. The buffer assembly 613 includes a first buffer rod 6131, a second buffer rod 6132, and a buffer element 6133. One end of the first buffer rod 6131 is fixedly connected to the second support frame 612, and the other end extends into the second buffer rod 6132. The buffer element 6133 is located within the second buffer rod 6132; preferably, the buffer element 6133 is a spring. One end of the buffer element 6133 is fixedly connected to the first buffer rod 6131, and the other end is fixedly connected to the inner wall of the second buffer rod 6132. The body of the replacement drive unit 62 is fixedly connected to the second support frame 612, and the output end of the replacement drive unit 62 is fixedly connected to the gun head placement seat 63. Preferably, the replacement drive unit 62 is a motor, which can drive the gun head placement seat 63 to rotate on the second support frame 612. In this embodiment, two gun head placement seats 63 are installed on the second support frame 612 to hold gun heads of different specifications, thereby meeting different testing requirements. The two gun head placement seats 63 are connected by a transmission belt 66, so that when the replacement drive unit 62 drives one gun head placement seat 63 to rotate, the other gun head placement seat 63 can rotate synchronously. A replacement detection element 64 is installed on the workbench 1 at the position of the gun head placement seat 63. Preferably, the replacement detection element 64 is a through-beam sensor, which can monitor the movement of the electrostatic gun 32 to the position of the gun head placement seat 63, further improving the reliability of gun head 321 replacement. When it is necessary to change the gun head of the electrostatic gun 32 to a different specification, the first robotic arm 311 drives the electrostatic gun 32 to move into the gun head placement seat 63 and makes the gun head of the electrostatic gun 32 abut against the inner wall of the gun head placement seat 63.

[0053] It should be noted that the gun head 321 of the electrostatic gun 32 is threadedly connected to the body of the electrostatic gun 32. After the gun head 321 of the electrostatic gun 32 abuts against the inner wall of a gun head placement seat 63, the replacement drive 62 drives the gun head placement seat 63 to rotate, causing the gun head 321 to be removed. Then, the first robotic arm 311 drives the body of the electrostatic gun 32 to move into another gun head placement seat 63. At this time, the replacement drive 62 reverses, installing the gun head 321 placed in the other gun head placement seat 63 onto the body of the electrostatic gun 32, completing the replacement of the gun head 321. During the contact between the electrostatic gun 32 and the gun head placement seat 63, the buffer 6133 is compressed, cushioning the electrostatic gun 32 and reducing the possibility of damage. Simultaneously, under the elastic force of the buffer 6133, the gun head placement seat 63 and the electrostatic gun 32 are pressed tightly together, thereby increasing the friction between the gun head placement seat 63 and the electrostatic gun 32 and improving the reliability of the gun head 321 replacement process.

[0054] At the same time, such as Figure 1 and Figure 8 As shown, the detection device 5 also includes a USB detection component 53, which is located on one side of the flipping device 7. The USB detection component 53 includes a USB detection driver 531, a USB detection element 532, and a USB detection controller 533. In this embodiment, the USB detection driver 531 includes a first driver 5311, a second driver 5312, and a third driver 5313. Preferably, the first driver 5311 is a linear module, the second driver 5312 is a two-axis linear module, and the third driver 5313 is a two-axis linear module. The body of the first drive unit 5311 is fixedly connected to the workbench 1. The output end of the first drive unit 5311 is fixedly connected to the bodies of the second drive unit 5312 and the third drive unit 5313. The output end of the second drive unit 5312 is fixedly connected to a USB detection element mounting base 534. The USB detection element 532 is mounted on the USB detection element mounting base 534. Through the cooperation of the first drive unit 5311 and the second drive unit 5312, the USB detection element 532 can move in two mutually perpendicular directions on the horizontal plane and in the vertical direction. The USB detection controller 533 is mounted on the workbench 1 and is electrically connected to the USB detection element 532. When the electronic device is clamped by the two clamping blocks 722, the first drive unit 5311 and the second drive unit 5312 drive the USB detection element 532 to move, so that the USB detection element 532 is inserted into the USB interface of the electronic device, thereby detecting the data transmission and charging performance of the electronic device.

[0055] In addition, such as Figure 1 and Figure 8As shown, a discharge device 8 is also installed on the workbench 1. The discharge device 8 includes a discharge controller 82 and a discharge element 81. The discharge controller 82 is electrically connected to the discharge element 81 and is installed on the workbench 1. A discharge element mounting base 83 is also fixedly connected to the output end of the third drive unit 5313. The discharge element 81 is installed on the discharge element mounting base 83. Through the cooperation of the first drive unit 5311 and the third drive unit 5313, the discharge element 81 can be driven to move in two mutually perpendicular directions on the horizontal plane and in the vertical direction, so that the discharge element 81 can be inserted into the USB interface of the electronic device to discharge the residual charge of the electronic device during the testing process, thereby reducing the impact of the residual charge on the testing process.

[0056] A wireless charging test board 9 is also installed on the workbench 1. When the electronic device is placed on the wireless charging test board 9, the wireless charging performance of the electronic device can be tested, which further improves the accuracy of electrostatic discharge detection of the electronic device.

[0057] The implementation principle of the electrostatic discharge protection testing system based on a multi-axis robotic arm in this application embodiment is as follows:

[0058] When electrostatic discharge testing of electronic equipment is required, the second robotic arm 41 drives the gripper 42 to move and move the electronic equipment to the designated position. At this time, the fixing drive 21 drives the fixing block 22 to move and fix the electronic equipment on the worktable 1.

[0059] After the electronic device is fixed on the workbench 1, the first robotic arm 311 drives the electrostatic gun 32 to move to the designated position for discharge. During the testing process, as needed, the first robotic arm 311 drives the electrostatic gun 32 to move into the gun head placement seat 63 for gun head replacement. Additionally, after testing one side of the electronic device is completed, the second robotic arm 41 drives the gripper 42 to move, causing the electronic device to move to the flipping device 7 for flipping. After flipping, the electronic device is moved by the second robotic arm 41 to the designated position for electrostatic discharge testing on the other side.

[0060] During the electrostatic discharge (ESD) detection process, different tests are performed on the electronic device: the contact driver 521 can drive the contact 522 to contact the screen of the electronic device for touch screen response detection; when the electronic device is clamped by the clamping mechanism 72, the USB detection driver 531 drives the USB workpiece to connect with the electronic device for data transmission and charging performance testing; the USB detection driver 531 drives the leakage element 81 to connect with the electronic device for leakage; the electronic device moves to the wireless charging detection board 9 for wireless charging performance testing; simultaneously, during the detection process, the vision inspection component 51 monitors the detection process of the electronic device.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
