Description

Technical Field

[0001] The utility model relates to the field of mesh electrode manufacturing, in particular to a conductive mesh positioning and pressing device, a welding platform 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 mesh positioning and pressing device, a welding table and a welding device, which can weld conductive meshes and conductive belts of different models and size requirements, improve the production efficiency of mesh electrodes and reduce the defective rate.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model provides a conductive mesh positioning and pressing device, including a positive and negative screw rod slider mechanism, and a plurality of vertical lifting mechanisms and a plurality of conductive mesh pressing mechanisms; the conductive mesh pressing mechanism is used to press the conductive mesh downward, and the conductive mesh pressing mechanism is driven by the vertical lifting mechanism to perform lifting and lowering movements, and the plurality of vertical lifting mechanisms are respectively arranged on the plurality of positive and negative screw rod sliders of the positive and negative screw rod slider mechanism, and are respectively driven by the positive and negative screw rod slider mechanism to move horizontally along the direction of travel of the conductive mesh.

[0008] Among them, the vertical lifting mechanism includes a vertical fixed block, a vertical screw rod, and a vertical screw rod motor.

[0009] A connecting guide rod is provided between the plurality of vertical movable blocks 1, and its rod body horizontally passes through each vertical movable block 1. The conductive mesh pressing mechanism includes a transverse screw motor, a transverse screw, and a transverse guide rod. The transverse screw motor is provided on the vertical movable block 1 and drives the horizontal transverse screw to rotate. A pressure wheel is provided at the lower end of the pressure wheel fixing block, which engages with the transverse screw via a thread. The transverse screw and the transverse guide rod are parallel. When the transverse screw rotates, the pressure wheel fixing block moves along the transverse guide rod.

[0015] Wherein: the conductive tape conveying mechanism and the conductive mesh conveying mechanism respectively convey the conductive tape and the conductive mesh along the first and second directions to the welding table, and the welding table is provided with a spot welder;

[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 existing technology, the present invention uses a positive and negative screw slider mechanism to control the lateral spacing between the conductive mesh positioning and clamping mechanisms, dynamically clamping conductive meshes of varying lengths. A vertical lifting mechanism adjusts the vertical height of the pressure rollers to accommodate conductive meshes of varying thicknesses. The horizontal screw motor on the conductive mesh clamping mechanism drives the rotation of the horizontal screws to adjust the spacing between the opposing pressure rollers, thereby accommodating conductive meshes of varying widths.

DETAILED DESCRIPTION

[0025] The present invention will now be further described with reference to the accompanying drawings. Figure 2 , Figure 2 The first embodiment of the present invention is a welding table, which includes a lifting frame 21, a rotating welding base 22, a conductive mesh positioning and pressing mechanism 23, and a conductive tape positioning device 24. Figure 2 The lower end of the rotary welding base 22 is mounted on a lifting frame 21 that can be raised and lowered. The upper end of the rotary welding base 22 is used to place the conductive mesh 8 and perform welding operations. The rotary welding base 22 is provided with conductive mesh positioning and clamping devices 23 for limiting and securing the conductive mesh 8, as well as conductive tape positioning devices 24 for controlling the position and length of the conductive tape 9.

[0026] See also Figure 3a -c. A second embodiment of the present invention provides the conductive mesh positioning and pressing device 23 described above, comprising a forward and reverse screw slider mechanism 231, two sets of vertical lifting mechanisms 232, and a conductive mesh pressing mechanism 233. The conductive mesh pressing mechanism 233 is used to press the conductive mesh 8 downward. The conductive mesh pressing mechanism 233 is driven to move up and down by the vertical lifting mechanisms 232. The vertical lifting mechanisms 232 are respectively disposed on the two forward and reverse screw sliders 2313 of the forward and reverse screw slider mechanism 231 and are respectively driven by the forward and reverse screw slider mechanisms 231 to move horizontally along the travel direction of the conductive mesh 8.

[0027] Further, see Figure 3a 、 3b The guide rails 2311 in the forward and reverse screw slider mechanism 231 are mounted on both sides of the base 224 of the rotary welding base 22, with their axes aligned with the direction of travel of the conductive mesh 8. The forward and reverse screw motor 2314 drives the horizontally arranged forward and reverse screw 2312. The rod body of the forward and reverse screw 2312 is sleeved with two forward and reverse screw sliders 2313 with oppositely arranged threads, each forming a screw nut mechanism. When the forward and reverse screw 2312 rotates, the two forward and reverse screw sliders 2313 move equidistantly in opposite directions along the guide rails 2311, thereby driving the vertical lifting mechanism 232 to move with it.

[0028] Further, see Figure 3a 、 3cThe vertical lifting mechanism 232 includes a vertical fixed block 2322, a vertical screw rod 2323, and a vertical screw motor 2321. The vertical screw motor 2321 is mounted on the forward and reverse screw slider 2313 of the forward and reverse screw slider mechanism via the vertical fixed block 2322. The vertical screw motor 2321 is mounted at the lower end of the vertical fixed block 2322. The lower end of the vertical screw rod 2323, which extends vertically upward, passes through the middle of the vertical fixed block 2322 and is connected to the output end of the vertical screw motor 2321. The vertical screw motor 2321 drives the vertical screw rod 2323 to rotate. The vertical moving block 2324 cooperates with the upper rod body of the vertical screw rod 2323 through the internal thread in the middle thereof, forming a screw nut mechanism.

[0029] Preferably, a connecting guide rod 2325 is provided between the two vertical moving blocks 2324, and the rod body of the connecting guide rod 2325 horizontally passes through the transverse through hole of the vertical moving block 2324. The connecting guide rod 2325 can ensure that the vertical moving blocks 2324 move up and down synchronously, while preventing the vertical moving blocks 2324 from rotating.

[0030] When the vertical screw motor 2321 rotates, the two vertical screws 2323 rotate to drive the two vertical moving blocks 2324 to move, thereby driving the conductive mesh pressing mechanism 233 provided on the vertical moving block 2324 to move up and down.

[0031] Further, see Figure 3c The conductive mesh pressing mechanism 233 includes a transverse screw motor 2331, a transverse screw 2332 and a transverse guide rod 2333. The transverse screw motor 2331 is arranged on the vertical moving block 2324 and drives the horizontally arranged transverse screw 2332 to rotate; the pressure wheel 2336 (rubber material) is arranged at the lower end of the pressure wheel fixing block 2334; the pressure wheel fixing block 2334 is provided with a pressure wheel motor 2337, and the pressure wheel motor 2337 drives the pressure wheel 2336 to rotate to push the conductive mesh 8 to move.

[0032] The pressure roller fixing block 2334 engages with the transverse screw rod 2332 via an internal thread in its center. The transverse screw rod 2332 and the transverse guide rod 2333 are parallel to each other. The pressure roller fixing block 2334 is inserted into the transverse guide rod 2333 via another through-hole in its center. The transverse guide rod 2333 prevents the pressure roller fixing block 2334 from rotating during movement and serves as a guide. When the transverse screw rod 2332 rotates, the pressure roller fixing block 2334 moves along the transverse guide rod. Preferably, a fixing ring 2335 is provided at the end of the transverse screw rod 2332 to limit the travel of the pressure roller fixing block 2334.

[0033] During use, the conductive mesh 8 and conductive tape 9 of the required welding specifications are selected, and the forward and reverse screw motor 2314 of the forward and reverse screw slider mechanism 231 drives the forward and reverse screw 2312 to rotate, causing the two forward and reverse screw sliders 2313 to move in opposite directions and at equal distances, adjusting the horizontal spacing between the pressure rollers 2336 on the same side to adapt to the length of the conductive mesh 8. The vertical screw motor 1 2321 of the vertical lifting mechanism 232 drives the vertical screw 1 2323 to rotate, causing the vertical moving block 1 2324 to move in the vertical direction, causing the conductive mesh pressing mechanism 233 connected to the vertical moving block 1 2324 to move in the vertical direction, changing the horizontal height of the pressure roller 2336 to adapt to the thickness of the conductive mesh 8 and compressing the conductive mesh 8; the horizontal screw motor 2331 of the conductive mesh pressing mechanism 233 drives the horizontal screw 2332 to rotate, causing the pressure rollers 2336 to move horizontally, adjusting the spacing between the opposing pressure rollers 2336 to adapt to the width of the conductive mesh 8.

[0034] The conductive mesh positioning and clamping device 23 controls the lateral spacing between the conductive mesh positioning and clamping mechanisms 233 via a forward and reverse screw-slider mechanism 231, dynamically compressing conductive meshes 8 of varying lengths. The vertical height of the pressure rollers 2336 is adjusted via a vertical lifting mechanism 232, accommodating conductive meshes of varying thicknesses. The horizontal screw motor 2331 on the conductive mesh clamping mechanism 233 drives the horizontal screw 2332 to rotate, adjusting the spacing between the opposing pressure rollers 2336 to accommodate conductive meshes 8 of varying widths.

[0035] See also Figure 1a 、 Figure 1b , Figure 1a 、 Figure 1b The third embodiment of the present invention is a welding device, comprising the welding station 2 described in the first embodiment, as well as a conductive tape conveying mechanism 1 and a conductive tape cutting mechanism 6, arranged sequentially along a first direction, and a conductive mesh conveying mechanism 5 and a conductive mesh cutting mechanism 4, arranged sequentially along a second direction. The conductive tape conveying mechanism 1 and the conductive mesh conveying mechanism 5 convey the conductive tape 9 and the conductive mesh 8, respectively, along the first and second directions to the welding station 2. The welding station 2 is equipped with a spot welder 3 for welding the conductive mesh 8 and the conductive tape 9.

[0036] As an example, a material box 7 is arranged on one side of the welding table 2 to collect the welded mesh electrodes. The spot welding machine 3 is arranged on one side of the welding table 2 and is arranged opposite to the conductive tape cutting mechanism 6.
