[0002] In today's era of highly developed electronic devices, mobile phones, as an indispensable electronic product in people's daily lives, require extremely high precision and quality assurance in their assembly and production process; however, static electricity has become a significant hidden danger affecting the quality of mobile phone assembly.

[0003] To address static electricity issues, traditional mobile phone assembly workshops typically employ conventional electrostatic discharge (ESD) protection measures, such as laying anti-static flooring and requiring workers to wear anti-static clothing and shoes. While these measures can reduce the generation and accumulation of static electricity to some extent, they often lack specificity and efficiency in releasing static electricity on specific assembly workbenches, especially around the mobile phones and their components being assembled.

[0004] Some simple assembly workbenches may only be equipped with basic grounding devices, which cannot quickly, continuously and comprehensively neutralize and release the static electricity frequently generated during the assembly process. Moreover, in actual assembly, multiple mobile phone components often need to be placed on the workbench and operated simultaneously. Different components are prone to mutual interference due to static electricity. Some existing general anti-static facilities are difficult to effectively and accurately control the static electricity of the local area where each component is located, and cannot meet the strict requirements for static electricity protection in the process of fine mobile phone assembly. At present, there is no workbench device that can achieve local static electricity control through physical isolation. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing anti-static facilities are insufficient to effectively and accurately control the static electricity of the local area where each component is located.

[0010] Furthermore, a spring is provided on the fixing rod, the spring is sleeved on the fixing rod, and the rotating shaft is connected to the partition plate by fixing bolts.

[0011] Furthermore, a connecting shaft is installed at the lower end of the turntable, the connecting shaft is rotatably connected to the worktable, and a damping pad is provided between the worktable and the connecting shaft, the damping pad being sleeved on the connecting shaft.

[0012] Furthermore, an anti-static wrist strap and a fixing frame are provided at the end of the workbench away from the turntable. A wire is installed on the anti-static wrist strap, and a connector is installed at one end of the wire. The connector is threadedly connected to the workbench. The fixing frame is installed on the workbench, and the anti-static wrist strap is fitted onto the fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting multiple anti-static pads on a turntable, with each anti-static pad equipped with an isolation component on its outer side, can effectively isolate and control static electricity in localized areas where different mobile phone components are located.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 The present invention relates to a mobile phone assembly electrostatic discharge device, comprising a workbench 1, a grounded copper foil inside the workbench, a turntable 2 on the upper surface of the workbench 1, a connecting shaft 3 installed at the lower end of the turntable 2, the connecting shaft 3 being rotatably connected to the workbench 1, the connecting shaft 3 being rotatably connected to the workbench 1, which allows the turntable 2 to rotate flexibly, facilitating the placement and assembly of mobile phone parts by operators in different positions.

[0024] In this embodiment, a damping pad 4 is provided between the workbench 1 and the connecting shaft 3. The damping pad 4 is made of silicone copper mesh composite material, which not only ensures smooth rotation, but also enhances the static discharge path through the grounding of the copper mesh. The damping pad 4 is fitted onto the connecting shaft 3. An anti-static wristband 8 and a fixing bracket 17 are provided at the end of the workbench 1 away from the turntable 2. The anti-static wristband 8 is a key component to ensure that the operator does not carry static electricity, thereby avoiding affecting the assembly of mobile phones. The operator needs to wear it on his / her hand. In actual operation, it can sense and collect the static electricity generated on the operator's body in real time.

[0025] In this embodiment, an antistatic wristband 8 is equipped with a wire 9, and a connector 10 is installed at one end of the wire 9. The connector 10 is threadedly connected to the workbench 1. The threaded connection ensures the stability of the connection and facilitates installation and disassembly, making subsequent maintenance and inspection easier. The fixing frame 17 is installed on the workbench 1, and the antistatic wristband 8 is fitted onto the fixing frame 17. Multiple antistatic pads 5 are provided on the turntable 2. The surface of the antistatic pad 5 is a carbon fiber conductive layer, and the bottom is embedded with a copper foil mesh. It is automatically connected to the internal grounding circuit of the turntable 2 through a spring pin to eliminate contact static electricity when the parts are placed.

[0026] Combination Figure 2 , Figure 3 As shown, multiple antistatic pads 5 are equipped with isolation components on their outer sides. The isolation components include partitions 11, and a rotating shaft 12 is installed on one side of the partition 11. The rotating shaft 12 is rotatably connected to the workbench 1. The surface of the partition 11 is covered with conductive material and connected to the grounding circuit of the workbench 1. The partition 11 can rotate flexibly around the rotating shaft 12, thereby realizing the blocking or opening operation of different areas on the turntable 2. A torsion spring 13 is sleeved on the rotating shaft 12. One end of the torsion spring 13 is installed on the partition 11, and the other end of the torsion spring 13 is installed on the workbench 1.

[0027] See Figure 1 , Figure 4 As shown, the torsion spring 13 plays a key role in storing force and resetting during the entire operation, providing elastic support for the flexible use of the partition 11. Fixed rods 14 are provided at both ends of the partition 11. The fixed rods 14 are slidably installed on the partition 11. Springs 15 are provided on the fixed rods 14 and are sleeved on the fixed rods 14. The rotating shaft 12 is connected to the partition 11 by a fixing bolt. The worktable 1 at the corresponding position of the fixed rod 14 is provided with a threaded hole 16. The fixed rod 14 is threadedly connected to the threaded hole 16. The end of the fixed rod 14 is designed with a tapered thread head, which forms a self-aligning lock with the circumferentially distributed threaded holes 16.

[0028] In this embodiment, the fixing rod 14 is threadedly connected to the threaded hole 16. Multiple threaded holes 16 are provided and distributed around the center circumference of the turntable 2. An air outlet 7 is provided at the rear end of the workbench 1. An ion fan 6 is provided on the workbench 1 on one side of the air outlet 7. The air outlet 7 at the rear end of the workbench 1 plays an important auxiliary role. It can guide the air in the working area in a reasonable way, so that the air can flow smoothly, thereby better assisting the ion fan 6 in playing its role.

[0029] The implementation principle is as follows: First, the partition 11 is opened. The partition 11 drives the torsion spring 13 to rotate through the rotating shaft 12 and store force. Then, the mobile phone parts to be assembled are placed on the anti-static pad 5 on the turntable 2. When it is necessary to distinguish different parts or prevent them from interfering with each other, the parts can be placed in different areas to avoid mutual interference of static electricity. Then, the partition 11 is released. The torsion spring 13 provides a certain restoring elastic force to shield the parts.

[0030] When it is necessary to keep the partition 11 open, after the partition 11 is opened, the driving rod 14 moves and is threadedly connected to the corresponding threaded hole 16, thereby fixing the angle of the partition 11 and preventing it from closing automatically. During the assembly process, the ion fan 6 works continuously and generates a large amount of ion airflow with positive and negative charges. This ion airflow can quickly neutralize the static electricity generated around the mobile phone components, and accurately control the static electricity of the local area where the mobile phone and its components are being assembled, so as to achieve continuous and all-round static electricity neutralization and release. This solves the problem that traditional simple grounding devices cannot quickly, continuously and all-roundly neutralize and release static electricity. At the same time, the air outlet 7 set at the rear of the workbench 1 can guide the air in the work area in a reasonable way, assisting the ion fan 6 to play a better role and remove some factors that may affect the operating environment due to static electricity neutralization, etc.

[0031] In addition, operators need to wear anti-static wrist straps 8 on their hands. The anti-static wrist straps 8 are connected to the workbench 1 by a connector 10 at one end of the wire 9. This can conduct static electricity away from the operator in time, preventing the static electricity from the operator's body from being conducted to the mobile phone parts being assembled. This further ensures the electrostatic protection effect throughout the mobile phone assembly process and meets the strict requirements for electrostatic protection in the process of fine mobile phone assembly.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
