Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic testing, in particular to a non-contact electrostatic field detection device. Background Technique

[0002] A non-contact electrostatic field testing device is a device used to detect and measure the intensity of an electrostatic field. It can work without directly contacting the object to be measured. This kind of testing device usually includes a highly sensitive sensor that can sense the changes in the electrostatic field in the surrounding environment and convert them into electrical signals for processing and display. Such devices are widely used in electronic manufacturing, laboratory research, quality control, and working environments where precise measurement of the electrostatic field intensity is required to ensure safety. By using a non-contact electrostatic field testing device, the damage of static electricity to sensitive electronic components can be effectively prevented, and the safety of staff can be guaranteed at the same time.

[0003] However, the existing non-contact electrostatic field detection devices are often fixedly installed at one position. Once the installation position is determined, it is difficult to change, and it is difficult to detect objects to be measured at different heights or positions, resulting in an inability to provide accurate and effective detection results and low practicability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a non-contact electrostatic field detection device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A non-contact electrostatic field detection device includes a fixed seat and a detector. A through slot is provided on the fixed seat. A first bracket is placed on the through slot. The first bracket is locked and installed on the fixed seat through a locking structure. The other end of the first bracket is locked and installed with a movable seat through a locking structure. A groove is provided on one side of the movable seat. A second bracket is locked and installed on the groove through a locking structure. A fixed block with a "convex" structure is also locked and installed on the first bracket and the second bracket through two locking structures. A cross through hole is provided at the protruding end of each of the fixed blocks. A fixed rod is locked and installed on the cross through hole through a locking bolt. The other end of the fixed rod is locked and installed with an electrostatic detection head through a locking bolt. Network ports are provided on both the electrostatic detection head and the detector. The two network ports are electrically connected through a network cable.

[0007] Furthermore, the first bracket and the second bracket have the same structure. The locking structure includes locking grooves disposed around the first bracket and the second bracket. Locking blocks are placed on the locking grooves. Fixed bolts are threadedly connected to the locking blocks. The threaded ends of the fixed bolts are respectively used to pass through the fixed seat, the movable seat, or the fixed block and abut against the end of the locking groove. The nut ends of the fixed bolts abut against the end face of the fixed seat, the movable seat, or the fixed block, for fixing the position of the first bracket, the movable seat, the second bracket, or the second fixed block.

[0008] Furthermore, both the locking groove and the locking block have a trapezoidal structure.

[0009] Furthermore, it also includes a workbench, on which a fixed plate is fixedly installed, a rotating gear plate is rotatably connected, a base is fixedly installed on the rotating gear plate, and a fixed base is installed on the top of the base. The fixed plate, the rotating gear plate, and the base are provided with a communicating movable hole, which is used for the support to pass through.

[0010] Furthermore, the lower end face of the rotating gear disk and the upper end face of the fixed disk are provided with corresponding annular grooves, and a number of balls are placed in the annular grooves.

[0011] Furthermore, the workbench is also provided with a moving component, on which a rack that meshes with the rotating gear disk is fixedly installed.

[0012] Furthermore, the upper end face of the fixed disk is provided with an annular groove II, and the bottom of the rotating gear disk is symmetrically provided with limiting posts, both of which are inserted into the annular groove II.

[0013] The beneficial effects of this utility model are:

[0014] This invention allows for the height adjustment of bracket one by unlocking the locking structure on the fixed base. Unlocking the locking structure on the movable base allows the movable base to move up and down, thus changing the height of bracket two. Unlocking the locking structure on the groove allows for the adjustment of the extension distance of bracket two. The fixed block is locked to bracket one and bracket two respectively by the locking structure. Unlocking the locking structure allows for the adjustment of the fixed block's position. Loosening the locking bolts on the fixed block allows the fixed rod to be placed in the cross-shaped through holes at different positions, and then tightening the locking bolts allows the electrostatic detection head to be adjusted according to actual conditions, ensuring effective electrostatic field detection of objects at different heights and distances, thus improving the practicality and detection effect of the device.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please refer to Figure 1-7 ;

[0026] A non-contact electrostatic field detection device includes a fixed seat 1 and a detector 2. A through groove 11 is provided on the fixed seat 1. A first bracket 3 is placed on the through groove 11. The first bracket 3 is locked and installed on the fixed seat 1 through a locking structure, allowing adjustment of the protruding height of the first bracket 3 in the vertical direction. The other end of the first bracket 3 is locked and installed with a moving seat 4 through a locking structure. A groove 41 is provided on one side of the moving seat 4. A second bracket 5 is locked and installed on the groove 41 through a locking structure. By unlocking the locking structure on the moving seat 4, the position of the moving seat 4 on the first bracket 3 can be adjusted, thereby changing the height position of the second bracket 5. By unlocking the locking structure on the groove 41, the protruding distance of the second bracket 5 can be changed. The first bracket 3 and the second bracket 5 are also locked and installed with a fixed block 6 in a "convex" shape structure through two locking structures. The two locking structures lock the two ends of the fixed block 6 respectively. By unlocking the locking structure, the user is allowed to adjust the position of the convex block. A cross through hole 61 is provided at the protruding end of several fixed blocks 6. A fixed rod 62 is locked and installed on the cross through hole 61 through a locking bolt 63. The other end of the fixed rod 62 is locked and installed with an electrostatic detection head 8 through a locking bolt 63. By unlocking the locking structure on the fixed block 6, the position of the fixed block 6 can be adjusted. By loosening the locking bolt 63, the fixed rod 62 can be placed on the cross through holes 61 at different positions, and then the locking bolt 63 is tightened, so that the electrostatic detection head 8 can detect the electrostatic field conditions at different positions.

[0027] Specifically, by unlocking the locking structure on the fixed seat 1, the first bracket 3 can be adjusted in terms of lifting. By unlocking the locking structure on the moving seat 4, the moving seat 4 can move up and down, thereby changing the height position of the second bracket 5. By unlocking the locking structure on the groove 41, the protruding distance of the second bracket 5 can be adjusted. Several fixed blocks 6 are respectively locked on the first bracket 3 and the second bracket 5 through the locking structure. By unlocking the locking structure, the position of the fixed block 6 can be adjusted, so that the electrostatic detection head 8 can adjust its position according to the actual situation, ensuring effective electrostatic field detection of objects at different heights and distances, improving the practicality and detection effect of the device. Network ports are provided on both the electrostatic detection head 8 and the detector 2. The two network ports are electrically connected through a network cable. The data detected by the electrostatic detection head 8 is transmitted to the detector 2 through the network cable. The detector 2 then displays the data on the panel, facilitating the operator to record the data and conduct analysis. In addition, multiple fixed blocks 6 can be installed on the first bracket 3 and the second bracket 5. By installing electrostatic detection heads 8 on the fixed blocks 6, multiple electrostatic detection heads 8 can detect the same-direction target, improving the detection accuracy, allowing simultaneous acquisition of multiple data points, and helping to more comprehensively analyze the electrostatic field situation.

[0028] In this embodiment, bracket 3 and bracket 5 have the same structure. The locking structure includes locking grooves 71 arranged around bracket 3 and bracket 5. Locking blocks 72 are placed on the locking grooves 71. Fixing bolts 73 are threadedly connected to the locking blocks 72. The threaded ends of several fixing bolts 73 are respectively used to pass through the fixed seat 1, the movable seat 4, or the fixing block 6 and abut against the end of the locking groove 71. The nut ends of several fixing bolts 73 abut against the end face of the fixed seat 1, the movable seat 4, or the fixing block 6, thereby fixing the position of bracket 3, the movable seat 4, bracket 5, or the fixing block 6. By loosening the fixing bolts 73, the user can adjust the height and extension distance of bracket 3 and bracket 5, as well as the specific position of the fixing block 6, to ensure that the electrostatic detection head 8 can be aligned with the object for detection, thereby enhancing the accuracy of electrostatic field detection.

[0029] In the previous embodiment, both the locking groove 71 and the locking block 72 are trapezoidal structures. The trapezoidal structure can provide a better contact surface, making the fit between the locking block 72 and the locking groove 71 tighter, improving the position fixation effect of the bracket 1 3, the movable seat 4, the bracket 2 5 and the fixed block 6, and ensuring the stability of the device.

[0030] In this embodiment, the non-contact electrostatic field detection device also includes a workbench 9, on which a fixed plate 91 is fixedly installed. A rotating gear plate 92 is rotatably connected to the fixed plate 91, and a base 93 is fixedly installed on the rotating gear plate 92. A fixed seat 1 is installed above the base 93. By rotating the rotating gear plate 92, the base 93 and the fixed seat 1 on it rotate together, so that the electrostatic detection head 8 can adjust the test angle according to actual needs, thereby realizing all-round electrostatic field detection. The fixed plate 91, the rotating gear plate 92 and the base 93 are provided with a connecting movable hole 94. The movable hole 94 is used for the support 3 to pass through, so that the support 3 can be moved downward for adjustment.

[0031] In this embodiment, the lower end face of the rotating gear disk 92 and the upper end face of the fixed disk 91 are provided with corresponding annular grooves 95. A number of balls 951 are placed on the annular grooves 95. Through the action of the balls 951, the friction between the rotating gear disk 92 and the fixed disk 91 can be reduced, thereby making the rotation of the rotating gear disk 92 smoother.

[0032] In this embodiment, the worktable 9 is also provided with a moving component 96. A rack 961 that meshes with the rotating gear disk 92 is fixedly installed on the moving component 96. Preferably, the moving component 96 is a common device in the field of moving mechanisms, specifically a combination of a motor, a lead screw, and a slider. The motor is fixedly connected to the lead screw, and the lead screw is threadedly connected to the slider. By starting the motor, the motor will drive the lead screw to rotate, thereby causing the slider to move along the lead screw. Since the slider is fixed together with the rack 961, the movement of the slider will drive the rack 961 to move together. The movement of the rack 961 will drive the rotating gear disk 92 that meshes with it to rotate, so that the fixed device installed on the base 93 can rotate accordingly, thereby automatically changing the detection angle of the electrostatic detection head 8 without manual rotation, improving the convenience of using the device.

[0033] In this embodiment, the upper end face of the fixed disk 91 is also provided with an annular groove 97, and the bottom of the rotating toothed disk 92 is symmetrically provided with limiting posts 98. Both limiting posts 98 are inserted into the annular groove 97. By inserting the limiting posts 98 into the annular groove 97, the rotation of the rotating toothed disk 92 is prevented from deviating or shaking, thereby improving the stability of the rotation of the rotating toothed disk 92.
