Description

Technical Field

[0001] The utility model relates to the technical field of battery production, and particularly relates to a detection tool for the strength of battery plates. Background Art

[0002] During the production process of storage batteries, it is necessary to apply lead paste on the plates and cure and dry it. During the use of storage batteries, they will be frequently vibrated. Therefore, there are relatively high requirements for the bonding strength between the active substances on the plates and the plates.

[0003] A patent document with the application number CN202220416323.9 discloses a device for detecting the strength of lead paste on lead-acid battery plates. When this device is used, first adjust the height of the support column according to requirements, and then fit and install a rectangular frame with adjusted width and length on the top of the support column. Place the plate to be detected into the rectangular frame, control the telescopic drive module to extend to clamp the plate with a clamping block, and adjust the plate to a horizontal state; then control the telescopic drive module to retract. At this time, the plate drops from the corresponding height, and observing the appearance of the plate after free fall or weighing the weight of the lead paste before and after its free fall can detect its adhesion strength. When this device detects the plate, it is necessary to fix the plate at a suitable height, which is rather troublesome when fixing the plate. At the same time, because the drop is manually operated, due to different operation methods or different contact points after landing, it cannot correctly reflect the strength of the plate to be detected.

[0004] A patent document with the application number CN202220237766.1 discloses a detection tool for the strength of lead-acid battery plates. The process of detecting the strength of lead-acid battery plates: Place the plate sample in the positioning groove of the rear wall plate, close to the rear wall plate. The rear wall plate is provided with a circular through hole for the shedding of the active substances on the plate sample. Contact the top pin with the plate surface of the plate sample, adjust the pointer of the torque meter to point to "0", and then rotate the torque handle to apply force to the plate sample with the top pin. When the top pin knocks off the active substances on the plate sample, the torque indicated by the pointer of the torque meter at this time is the plate strength of the plate sample. This detection tool is not convenient for stabilizing plates of different sizes to be detected, is not convenient for adjusting the distance between the plate to be detected and the torque testing device, and is not convenient for removing the torque testing device for maintenance.

[0049] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0050] Embodiment 1: Refer to Figures 1-4 As shown, a battery plate strength detection tooling includes a bottom plate 1. A baffle 3 is slidably arranged in the length direction of the bottom plate 1, and the baffle 3 is perpendicular to the bottom plate 1. Specifically, a long groove 2 is opened at the upper end of the bottom plate 1, and the length direction of the long groove 2 is parallel to the length direction of the bottom plate 1. The convex block at the lower end of the baffle 3 is slidably clamped in the long groove 2.

[0051] A through hole 6 is opened on the baffle 3, and a stabilizing component capable of stabilizing the plate to be tested is arranged on the baffle 3.

[0052] The stabilizing component includes two sliding grooves 10 opened on the baffle 3. The through hole 6 is located between the two sliding grooves 10. The sliding grooves 10 are opened on the side of the baffle 3 facing the detection device. The length direction of the sliding grooves 10 is perpendicular to the moving direction of the baffle 3. Slide blocks 25 are slidably clamped in the sliding grooves 10. A pin rod 8 is fixed on each of the slide blocks 25. A pressure rod 7 is arranged on one side of the baffle 3. The pressure rod 7 is located between the baffle 3 and the detection device. The pin rod 8 penetrates through the pressure rod 7, and the pin rod 8 is slidably connected with the pressure rod 7. The pressure rod 7 is connected to the end of the pin rod 8 far from the slide block 25 through a first spring 9.

[0053] When the slide block 25 moves in the sliding groove 10, the height of the pressure rod 7 can be adjusted. When the pressure rod 7 moves away from the baffle 3, the first spring 9 is stretched. Place the plate to be detected between the baffle 3 and the pressure rod 7, and then release the pressure rod 7. Under the elastic force of the first spring 9, the pressure rod 7 can squeeze and stabilize the plate to be tested on the baffle 3. When stabilizing the plate to be tested, it is necessary to make the pressure rod 7 misaligned with the through hole 6.

[0054] A position adjustment component capable of adjusting the position of the baffle 3 is arranged on the bottom plate 1.

[0055] The position adjustment assembly includes a fixing plate 4 fixed on the bottom plate 1. The baffle 3 is located between the fixing plate 4 and the detection device. A bolt 5 is threadedly connected to the fixing plate 4. The bolt 5 penetrates through the fixing plate 4, and the axial direction of the bolt 5 is parallel to the movement direction of the baffle 3. The bolt 5 is rotatably connected to the baffle 3. By rotating the bolt 5, the distance between the baffle 3 and the detection device can be adjusted, thereby facilitating the adjustment of the position of the test electrode plate stably placed on the baffle 3 and the detection device.

[0056] A fixing block 11 is fixed on the bottom plate 1 on one side of the baffle 3. An arc-shaped groove is formed in the fixing block 11. The detection device is placed in the arc-shaped groove. The detection device is concentric with the through hole 6. A pressing block 18 is arranged above the detection device. The pressing block 18 tightly abuts against the upper end of the detection device. The pressing block 18 is detachably and fixedly connected to the fixing block 11.

[0057] The detection device includes a housing 12. The pressing block 18 tightly abuts against the upper end of the housing 12. A rotating rod 14 is threadedly connected concentrically in the housing 12. The rotating rod 14 penetrates through the housing 12. A display screen 13 is fixed at the upper end of the housing 12. One end of the rotating rod 14 facing the baffle 3 is fixed with a pressure sensor 26. The pressure sensor 26 is electrically connected to the display screen 13 through a controller. A top rod 15 is fixed on the pressure receiving end of the pressure sensor 26. The top rod 15 is concentrically arranged with the rotating rod 14.

[0058] During detection, the test electrode plate is stabilized on the baffle 3 through the pressing rod 7. Then, the bolt 5 is rotated to adjust the distance between the test electrode plate on the baffle 3 and the top rod 15. Then, the rotating rod 14 is rotated to make the top rod 15 move towards the test electrode plate. When the top rod 15 contacts the test electrode plate, as the pressure of the top rod 15 on the test electrode plate continuously increases, the pressure of the top rod 15 on the test electrode plate is detected in real time by the pressure sensor 26, and the pressure value of the top rod 15 on the test electrode plate is displayed on the display screen 13. When the active material on the test electrode plate is knocked off by the top rod 15, stop rotating the rotating rod 14. The maximum value displayed on the display screen 13 is the strength of the test electrode plate.

[0059] A vertical insertion rod 19 is fixed at the lower end of the pressing block 18. The insertion rod 19 is inserted into a vertical groove 20 on the fixing block 11. A horizontal groove 21 communicating with the vertical groove 20 is formed in the fixing block 11. An insertion strip 22 is slidably clamped in the horizontal groove 21. The insertion strip 22 is connected to the fixing block 11 through a second spring 23. The insertion strip 22 penetrates through a slot hole on the insertion rod 19. A handle rod 24 is fixed on the insertion strip 22.

[0060] When it is necessary to disassemble and maintain the detection device, the insertion strip 22 is pulled through the handle rod 24 to make the insertion strip 22 withdraw from the slot hole of the insertion rod 19. Then, the pressing block 18 can be removed from the fixing block 11. Subsequently, the housing 12 can be taken out from the arc-shaped groove of the fixing block 11, thereby maintaining the detection device.

[0061] Embodiment 2: On the basis of Embodiment 1, with reference to Figure 1 and Figure 3 As shown, front blocking rods 16 and rear blocking rods 17 are respectively fixed to the front and rear ends of the fixing block 11. The front blocking rod 16 blocks the front end of the housing 12, and the rear blocking rod 17 blocks the rear end of the housing 12.

[0062] By providing the front blocking rod 16 and the rear blocking rod 17, the front blocking rod 16 and the rear blocking rod 17 can limit the housing 12. When detecting the strength of the to-be-tested electrode plate, the stability of the detection device can be improved, and thus the detection accuracy can be improved.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
