Description

Technical Field

[0001] The utility model relates to the field of mesh electrode manufacturing, in particular to a conductive belt positioning device, a welding table and a welding device. Background Art

[0002] Mesh electrodes are used in many fields. For example, in the biomedical field, mesh electrodes are used for biomedical sensors and physiological monitoring equipment; in the environmental testing field, they are used to monitor the electrical conductivity in the soil to assess soil moisture and salinity; in the field of oil and gas exploration, they are used to measure underground resistivity to obtain underground structure and geological information.

[0003] The mesh electrode is made of a conductive tape and a conductive net welded together. Depending on the field and equipment in which it is used, the mesh electrode has a variety of sizes and models, such as the length, width and thickness of the conductive net or conductive tape. The size and welding position of the conductive net and the conductive tape need to be precisely controlled. At the same time, different positions of a conductive net require one or more conductive tapes to be welded depending on the model. The size and model are complex and the precision requirements are high.

[0004] Currently, in actual production, different types of mesh electrodes are manufactured by manually replacing molds corresponding to different models. The conductive mesh and conductive tape are cut separately on different equipment, and then manually positioned using molds of different models, and then welded using a spot welder. For electrodes that require welding multiple conductive tapes, the conductive mesh needs to be positioned and welded multiple times. Therefore, there are the following shortcomings: (1) The conductive mesh and conductive tape are cut separately, and are welded first, and then manually positioned using molds, which is inefficient, low-precision, and has a high defective rate; (2) Mesh electrodes with multiple conductive tapes require multiple manual positioning, which is time-consuming and labor-intensive. Utility Model Content

[0005] The utility model aims to solve the existing problems and provides a conductive tape positioning device, a welding table and a welding device, which can weld conductive meshes and conductive tapes of different models and size requirements, improve the production efficiency of mesh electrodes and reduce the defective rate.

[0007] Among them, the support block is also provided with a block screw motor and a pressure block screw motor. The conductive belt block and the pressure block fixed block cooperate with the block screw and the pressure block screw through threads. The block screw motor and the pressure block screw motor respectively drive the block screw and the pressure block screw to rotate, thereby driving the conductive belt block and the pressure block fixed block to move along the axis of the rod body of the support block.

[0008] Wherein, a conductive belt sensor is provided at the groove of the conductive mesh pressing block.

[0009] The conductive mesh pressing block is driven by a pressing block motor to rotate in a horizontal direction.

[0010] Among them, a supporting gear rod motor is also provided on the vertical moving block 2, and the output rod of the supporting gear rod motor is connected to the supporting gear rod and drives it to rotate in the vertical direction.

[0011] Wherein, the upper end of the vertical guide rod and / or the vertical screw rod 2 is provided with a fixing ring 2 for limiting the moving stroke of the vertical moving block 2.

[0012] The utility model also provides a mesh electrode welding table, including a lifting frame, a rotary welding base, a conductive mesh positioning and pressing mechanism and a conductive belt positioning mechanism. The side of the rotary welding base is provided with the above-mentioned conductive belt positioning device for controlling the welding length of the conductive belt.

[0013] The lower end of the rotary welding base is arranged on a lifting frame that can move up and down, and the upper end surface of the rotary welding base is used to place the conductive mesh and perform welding operations.

[0016] The conductive tape cutting mechanism and the conductive mesh cutting mechanism are used to cut the input conductive mesh / conductive tape. Compared to the prior art, the present invention uses the conductive tape positioning device's stopper screw motor to rotate and adjust the position of the conductive tape stopper. A conductive tape sensor is provided on the conductive tape stopper to detect whether the conductive tape conveyed by the conductive tape conveyor mechanism has reached the specified position, thereby accommodating conductive tapes of varying lengths. Furthermore, the horizontal position of the conductive mesh pressing block is adjusted by the conductive tape positioning device's pressing block screw and pressing block motor, thereby accommodating conductive webs of varying widths.

[0017] Furthermore, the utility model can produce mesh electrodes of various models and sizes, and can adjust the welding point position and the positioning fixture position without replacing the fixture; the conductive mesh can be multi-sidedly welded to the conductive strip without the need for manual multiple positioning, with high welding accuracy, low defective rate and efficient production.
