[0002] As the core component of lead-acid batteries, the plate plays an important role in the use of the battery. The plate is composed of a grid and lead paste. In order to enhance the mechanical strength between the grid and the lead paste, the plate must go through a curing process after coating. This process must be carried out in a special curing chamber that controls the temperature, humidity, and duration of the curing and drying steps.

[0003] The mechanical strength of the plate determines the bonding force between the grid and the lead paste, directly affects the cycle life of the battery, and is an important indicator for measuring the quality of the plate. The mechanical strength test of the plate is an indispensable part of the manufacturing of battery plates. The common test method is to weigh the plate first, then let the plate fall freely from a height of 1m above the ground, and finally weigh the plate. The plate drop strength is characterized by calculating the weight reduction ratio of the plate.

[0027] like Figures 1 to 5 As shown, a lead-acid battery plate drop strength test tool includes a bracket 1, the bracket 1 is a frame structure, and two adjacently arranged flip plates 2 are arranged on the top of the bracket 1. The sides of the flip plates 2 that are away from each other are hinged to the bracket through hinge shafts respectively. The flip plates 2 have a closed state when arranged horizontally, and an open state in which the sides that are close to each other are tilted downward and away from each other after rotation. When the flip plates 2 are in the closed state, the two flip plates 2 are in a horizontal state, the two flip plates 2 are close to each other, and then the plate to be tested is placed on the two flip plates 2. When the flip plates 2 are opened, the two flip plates 2 rotate separately, and the sides that are close to each other rotate downward, so that the distance between the two flip plates 2 gradually increases, and finally the plate falls freely.

[0028] The lead-acid battery plate drop strength detection tool of the utility model also includes a driving mechanism for driving the two flip plates 2 to open or close, and the driving mechanism includes a foot pedal 3 arranged at the bottom of the bracket 1, and a pull rope 4 connected to the foot pedal 3 at one end and used to pull the flip plate 2 to rotate at the other end. When in use, the user steps on the foot pedal 3 to drive the pull rope 4, so that the pull rope 4 pulls the flip plate 2 to rotate.

[0029] One end of the two hinge shafts corresponding to the two turning plates 2 extends out of the bracket 1 on the same side, and a turning disc 5 is respectively provided. During the rotation of the turning disc 5, the turning plate 2 is driven to rotate. One end of the pull rope 4 is connected to the turning plate 2, and when the foot pedal 3 is stepped on, the pull rope 2 drives the turning disc 5 to rotate, so that the turning plate 2 rotates and opens.

[0030] The driving mechanism further includes a multi-link mechanism. The two ends of the multi-link mechanism are respectively hinged to the turning disc 5, so that the two turning discs 5 are linked and controlled through the multi-link mechanism. The pull rope 4 drives the multi-link mechanism to move, driving the turning disc 5 to rotate.

[0031] The turning disc 5 has an eccentrically arranged mounting protrusion 6. The eccentric arrangement means that the mounting protrusion 6 is not arranged at the center of the surface of the turning disc 5, but is arranged on the outer periphery, preferably at a position close to the edge. The multi-link mechanism includes an intermediate link 7 and two side links 8. One ends of the two side links 8 are respectively hinged to the two ends of the intermediate link 7, and the other ends are respectively hinged to a turning disc 5 through the mounting protrusion 6 on the turning disc 5. A driving rod 9 is further provided on the intermediate link 7. One end of the driving rod 9 is fixed to the middle of the intermediate link 7, and the other end is connected to the pull rope 4. The pull rope 4 drives the intermediate link 7 by pulling the driving rod 9. The intermediate link 7 drives the two side links 8 on both sides, and then each of the two side links 8 drives a turning disc 5.

[0032] The lead-acid battery plate drop strength detection tooling of the present utility model further includes a return spring 10. The driving rod 9 biases towards one of the turning discs 5. One end of the return spring 10 is connected to one end of the intermediate link 7, and the other end is connected to the bracket 1. The direction of the return and stretching of the return spring 10 is opposite to the direction of the pull rope 4 driving the intermediate link 7 to rotate.

[0033] As Figure 5 shown, after stepping on the foot pedal 3, the pull rope 4 pulls down one end of the driving rod 9. The driving rod 9 rotates the intermediate link 7 together with the two side links 8, so that the turning disc 5 rotates to open the turning plate 2.

[0034] The height of the turning plate 2 is 1 m. Thus, the plate freely falls from a height of 1 m during detection. Generally, in the prior art, when detecting the drop strength of the plate, a height of 1 m is used for falling.

[0035] When the lead-acid battery plate drop strength detection tooling of the present utility model is in use, the plate to be detected is placed on the two turning plates 2, generally in the middle. Then the user steps on the foot pedal 3 to control the pull rope 4 to pull down, thereby pulling down one end of the driving rod 9, driving the multi-link mechanism to move, driving the turning disc 5 to rotate, and thus opening the turning plate 2 to make the plate freely fall. By calculating the weight change of the plate before and after the fall, the mass and proportion of the fallen lead paste can be calculated, so as to obtain the plate drop strength situation.
