Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to a device for detecting the bonding effect of grid nodes in a mesh panel. Background Technology

[0002] Maintenance-free lead-acid batteries for automotive starting consist of plates and electrolyte. The plates are made up of grids and lead paste, with the grids primarily serving as the framework and transmitting current. The quality of the grids is particularly important; if grid nodes detach, it will reduce the overall strength of the grids, increase internal resistance, reduce conductivity, and affect current transmission.

[0003] Currently, the method involves manually pulling on the lead mesh of the grid to observe whether any nodes have detached. However, the deformation caused by pulling is small, making it impossible to detect issues with the bonding strength. Furthermore, the amount of deformation can easily lead to misjudgments. When determining whether the ribs are detached from the battery, the inconsistent tensile strength of each node makes the judgment unreliable; some nodes cannot be detected, resulting in omissions.

[0004] Therefore, a device needs to be designed to detect the bonding strength of the grid nodes to ensure that the performance indicators of the grid meet the requirements. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting the bonding effect of mesh plate grid nodes, which can effectively detect the bonding strength of each node and intuitively discover the bonding condition of the bonding points.

[0006] The technical solution of this utility model is: a device for detecting the joint effect of a mesh grid node, characterized in that: it consists of a clamping device, a rotating device, and a counterweight device; wherein, the clamping device is a clamp that cooperates with the grid frame; the rotating device is provided with a winding rod, which is wound and cooperates with the grid frame; the counterweight device consists of a counterweight block, a fixed wheel, and a traction rope, the traction rope passing around the fixed wheel, and its two ends being connected to the counterweight block and the clamping device respectively.

[0007] In the technical solution of this utility model, the winding rod is provided with a notch that matches the grid frame.

[0008] The rotating device in the technical solution of this utility model includes a base and a rotating mechanism disposed on the upper part of both sides of the base; the inner end of the rotating mechanism can be connected and cooperated with the end of the winding rod.

[0009] In the technical solution of this utility model, the outer end of the rotating mechanism is connected to a rotating mechanism.

[0010] The rotating mechanism described in the technical solution of this utility model consists of a rotating handle and a rotating disk or circular rod frame.

[0011] In the technical solution of this utility model, the bottom center of the clamp is provided with a T-shaped clamping groove that cooperates with the plate frame.

[0012] The clamp in the technical solution of this utility model consists of a clamp body, two clamping plates, two clamping blocks, two first connecting rods, and a second connecting rod.

The lower ends of the two clamping plates are respectively connected to the two clamping blocks. The two ends of the second connecting rod are respectively hinged to the lower part of the two clamping plates.

[0014] In the technical solution of this utility model, the counterweight is a rectangular counterweight; the fixed platform is a rectangular plate with an area larger than the bottom area of ​​the counterweight.

[0015] In the technical solution of this utility model, the clamp is located directly above the winding rod; the fixed wheel is located above the clamp.

Hold the grid in place, attach the other side frame of the grid to the winding rod, rotate the winding rod clockwise to wind the grid onto the surface of the winding rod, and after winding, rotate counterclockwise to restore the grid to a flat state. Continue to rotate counterclockwise to wind the grid in the opposite direction onto the surface of the winding rod. After winding in the opposite direction, rotate clockwise to restore the grid to a flat state. Repeat the above winding process as set. After completion, observe whether there is any detachment at the joint of the grid rib nodes. If there is no detachment, it meets the requirements.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, one embodiment of the device for detecting the joint effect of mesh panel nodes according to the present invention consists of a clamping device 2, a rotating device 3, a counterweight device and a fixed platform 6, with the clamping device 2 located directly above the rotating device 3.

[0025] The rotating device 3 includes a base, a rotating mechanism disposed on the upper sides of both sides of the base, a rotating mechanism, and a winding rod 4. The rotating mechanism consists of a rotating handle and a rotating disk, one of which has a rotating handle. The inner side of the rotating disk is connected to the outer end of the rotating mechanism. The two ends of the winding rod 4 can be connected and engaged with the inner end of the rotating mechanism. The winding rod 4 has notches that engage with the frame of the grid 5, allowing it to hook onto the frame of the grid 5.

[0026] The clamping device 2 is a clamp that mates with the frame of the grid 5. The clamp consists of a clamping body, two clamping plates, two clamping blocks, two first connecting rods, and a second connecting rod. The upper ends of the two clamping plates are hinged to one end of each of the two first connecting rods, and the other ends of the two first connecting rods are hinged to the upper part of the clamping body. The lower ends of the two clamping plates are connected to the two clamping blocks, and both ends of the second connecting rod are hinged to the lower parts of the two clamping plates. The clamp is located directly above the winding rod 4. Lifting the upper ends of the two clamping plates or the outer ends of the two first connecting rods upwards separates the two clamping blocks; conversely, pressing the upper ends of the two clamping plates or the outer ends of the two first connecting rods downwards brings the two clamping blocks closer together. The spacing between the two clamping blocks can be adjusted to suit different specifications of the grid 5. Alternatively, the clamp can be an integral clamp with a T-shaped clamping groove at the center of the bottom that mates with the frame of the grid 5.

[0027] The counterweight device consists of a counterweight block 7, a fixed wheel 1, and a traction rope. The fixed wheel 1 is located above the gripper. The traction rope passes over the fixed wheel 1, and its two ends are connected to the counterweight block 7 and the gripper, respectively. The counterweight block 7 is a rectangular counterweight block, and a series of counterweight blocks 7 can be used to meet the counterweight setting requirements.

[0028] The fixed platform 6 is a rectangular plate with an area larger than the base area of ​​the counterweight 7, and is located directly below the counterweight 7. The fixed platform 6 is used to place the counterweight 7.

[0029] Strength testing steps for each node of the expanded metal mesh grating:

[0030] 1. Adjust the distance between the two clamping blocks, and insert one side edge of the grid 5 into the clamp from above between the two clamping blocks to clamp and fix it in place;

[0031] 2. Place the other side edge of the grid 5 into the notch of the winding rod 4 and hook the other side edge of the grid 5.

[0032] 3. The clamp is connected to a counterweight 7 with a set weight via a traction rope. The traction rope passes around the fixed wheel 1. There is a fixed platform 6 at the bottom of the counterweight 7 for placing the counterweight 7.

[0033] 4. Slowly and evenly rotate the handle clockwise to make a circular motion, which will drive the winding rod 4 to rotate, and the grid 5 will be wound on the surface of the winding rod 4.

[0034] 5. After winding is complete, turn the rotating handle counterclockwise to restore the grid 5 to its flat state;

[0035] 6. Continue to rotate the handle counterclockwise, and the grid 5 is wound in the opposite direction onto the winding rod 4;

[0036] 7. Rotate the handle clockwise to restore the grid 5 to its flat state;

[0037] 8. After repeating the above three times, observe whether there is any detachment at the joint of the 5th rib node 8 of the grid. If there is no detachment, it meets the requirements. If there is detachment, production needs to be adjusted in time.
