Description

Technical Field

[0001] The invention relates to the field of battery plates for electric power-assisted vehicles, and in particular to a device for improving the weight consistency of battery plates for electric power-assisted vehicles. Background Art

[0002] The battery plate is the basic component of the battery, which receives the charged electrical energy and releases the electrical energy to the outside. The plates are divided into positive plates and negative plates. The active material on the positive plate is usually lead dioxide, which is brown-red; the active material on the negative plate is sponge-like pure lead, which is blue-gray. During the discharge process, the active materials of the positive and negative electrodes will react with the sulfur in the electrolyte to generate lead sulfate, and at the same time release electrical energy to power the electric assisted vehicle.

[0003] The patent application with announcement number CN119092648A is a plate weight adjustment system and method used in a battery plate production line, wherein the system includes a controller and a weight sampling mechanism and a weight adjustment mechanism respectively connected to the controller signal; the weight sampling mechanism includes a weighing assembly arranged on one side of the production line, and a sampling assembly that reciprocates between the weighing assembly and the production line to transfer the plates; the weight adjustment mechanism includes a first drive assembly whose output end is connected to the paste bucket adjustment screw on the production line to adjust the gap between the paste bucket and the roller. The method is implemented using the above system, including S1, sampling weighing and S2, weight adjustment. The present invention realizes the automatic adjustment of the plate weight on the battery plate production line. By monitoring the weight of the plates on the production line and optimizing the gap between the paste bucket and the roller according to the monitoring situation, the consistency of the weight of the plates in the same batch can be effectively improved to ensure the quality of the product.

[0004] In the production process of existing battery plates, it is necessary to ensure the consistency of their weight in order to ensure the quality of the battery. Therefore, after the production is completed, the battery substrates with the same weight or within the allowable range of the production process error need to be classified for subsequent battery production. The existing measurement method requires each group of battery plates to be weighed and measured separately and the data is recorded. Finally, the battery plates that meet the requirements are classified and produced. The existing weighing method requires a comparative standard weight, and this comparative weight is pre-made in advance according to the production process. The weight difference during the comparison is compared with the process requirements to detect whether the battery plates meet the requirements. After the data is recorded, the entire weighing process is finally classified. However, the existing production process will have a certain weight error, and the production process also allows a certain error. After the error occurs, the existing weighing method needs to calculate the error value and compare it to determine whether it meets the production needs. This weighing measurement method is relatively cumbersome and difficult to meet the production needs of batteries.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The present invention provides Figure 1-7 A device for improving the weight consistency of battery plates of an electric power-assisted vehicle is shown, comprising a support platform 001, a fixing frame 101 is symmetrically installed above the support platform 001, a connecting shaft 102 is rotatably connected between two sets of fixing frames 101, and a docking rod 103 is fixedly connected to the connecting shaft 102 through the connecting shaft 102;

[0033] The connecting shaft 102 rotates between the two sets of fixing frames 101, so that the two sides of the docking rod 103 swing left and right, thus showing a balance effect, and the rotation distance of the connecting shaft 102 is limited, so as to prevent the docking rod 103 from shaking left and right in a large range.

[0034] The weighing and measuring assembly 002 disposed at one end of the docking rod 103 includes a connecting cavity 201, which is opened inside the docking rod 103, a screw rod 202 is rotatably connected in the connecting cavity 201, a hexagonal rotating block 203 is fixedly connected to one side of the screw rod 202, and the hexagonal rotating block 203 is located outside the docking rod 103;

[0035] The hexagonal rotating block 203 can drive the screw rod 202 to rotate in the connecting cavity 201 .

[0036] The placement and fixing assembly 003 arranged at the end of the docking rod 103 away from the weighing and measuring assembly 002 includes a bearing plate 301, which is installed on the side of the docking rod 103 away from the hexagonal rotating block 203, and the bearing plate 301 is symmetrically installed with connecting seats 302, and a rotating shaft 303 is installed between two groups of connecting seats 302, and an L-shaped fixing plate 305 is sleeved on the rotating shaft 303, and two groups of L-shaped fixing plates 305 are symmetrically arranged on the bearing plate 301;

[0037] Through the cooperation between the connecting seat 302 and the rotating shaft 303 , the L-shaped fixing plate 305 can be rotated on the carrying plate 301 .

[0038] The weighing comparison assembly 004 disposed between the two sets of fixing frames 101 includes a semicircular plate 401 . The semicircular plate 401 is installed below the docking rod 103 . A cross groove 402 is formed on the surface of the semicircular plate 401 .

[0039] The docking rod 103 can drive the semicircular plate 401 to swing left and right, thereby causing the cross slot 402 to swing left and right.

[0040] Furthermore, in the above structure, the weighing and measuring component 002 also includes an internal thread block 204 , which is threadedly connected to the screw rod 202 , and a slide groove 205 is symmetrically provided on the inner wall of the connecting cavity 201 .

[0041] By rotating the screw rod 202 , the screw rod 202 can drive the internal thread block 204 to slide in the connecting cavity 201 .

[0042] Furthermore, in the above structure, a counterweight block 206 is sleeved on the docking rod 103 , a connecting block 212 is fixedly connected between the counterweight block 206 and the internal thread block 204 , and the connecting block 212 is slidably connected to the corresponding slide groove 205 .

[0043] The connecting block 212 slides along the slide groove 205, so that the internal thread block 204 can drive the counterweight block 206 to move. Due to the movement of the counterweight block 206, the docking rod 103 is tilted. Since the weight of the counterweight block 206 is fixed, the moving distance of the counterweight block 206 is proportional to the tilt angle of the docking rod 103 after bearing the weight.

[0044] Furthermore, in the above structure, a cavity 207 is defined in the docking rod 103 , a slider 208 is slidably connected in the cavity 207 , and a connecting rod 209 is fixedly connected between the slider 208 and the internal thread block 204 .

[0045] The connecting rod 209 can enable the sliding block 208 to slide in the cavity 207 when the internal thread block 204 moves.

[0046] Furthermore, in the above structure, an indicator rod 210 is installed above the slider 208 , a scale ruler 211 is installed above the docking rod 103 , and the indicator rod 210 is located above the scale ruler 211 .

[0047] The slider 208 drives the indicator rod 210 to move along the surface of the scale 211 , so as to obtain the moving distance of the slider 208 and indirectly know the moving distance of the counterweight 206 .

[0048] Furthermore, in the above structure, the placement and fixing component 003 also includes a torsion spring 304 , which is sleeved with the rotating shaft 303 , and a docking hole 306 is opened on the surface of the L-shaped fixing plate 305 .

[0049] The position of the L-shaped fixing plate 305 can be limited by the torsion spring 304 so that one surface of the L-shaped fixing plate 305 is always in contact with the supporting plate 301 .

[0050] Furthermore, in the above structure, a fixing rod 307 is connected through the docking hole 306, a rubber block 309 is installed below the fixing rod 307, a spring 308 is sleeved on the fixing rod 307, and the spring 308 is respectively fitted with the rubber block 309 and the docking hole 306 at the top and bottom.

[0051] By rotating the L-shaped fixing plate 305, the rubber block 309 fits the battery plate, and the battery plate fits the supporting plate 301, so that the fixing rod 307 slides along the docking hole 306 and squeezes the spring 308, so that the rubber block 309 and the supporting plate 301 complete the fixation of the battery plate.

[0052] Furthermore, in the above structure, the weighing comparison component 004 also includes a horizontal laser 403, which is installed in a set of fixed frames 101, and a cross connecting groove 404 is opened on one side of the other set of fixed frames 101. The cross connecting groove 404 is at the same horizontal position as the cross through groove 402 and the horizontal laser 403.

[0053] The horizontal laser 403 irradiates a cross laser, passes through the cross through groove 402 , and finally irradiates the cross connecting groove 404 .

[0054] Furthermore, in the above structure, a plurality of laser detectors 405 are installed inside the cross connection groove 404, a data analyzer 406 is installed on one side of the fixed frame 101, and the data analyzer 406 is linearly connected to the plurality of laser detectors 405, a display light 407 is linearly connected to one side of the data analyzer 406, and the display light 407 is fixedly connected to the top of the support platform 001.

[0055] The laser detector 405 in the cross-connecting groove 404 can detect the laser irradiated by the horizontal laser 403, so that the detection data can be transmitted to the data analyzer 406. Finally, it can be known whether the detection is passed through the display light 407. When the laser does not completely pass through the inside of the cross-connecting groove 402, it means that the docking rod 103 is in an unbalanced state.

[0056] like Figure 1-7As shown, by adjusting the counterweight 206 to its corresponding position according to the production standard, so that its weight reaches the required level, and then by using one hand to move the two groups of L-shaped fixing plates 305 to make them rotate in opposite directions, the battery plate is placed on the carrier plate 301, and the two groups of L-shaped fixing plates 305 are slowly loosened at this time, so that the torsion spring 304 drives it to reset, so that the rubber block 309 fits to the surface of the battery plate, and the spring 308 is squeezed to fix the battery plate. At this time, the docking rod 103 will enter a balanced state, and the laser detector 405 will emit a laser to make the light pass through the cross groove 402, and perform laser detection through the laser detector 405 inside the cross connecting groove 404. Finally, after analysis by the data analyzer 406, the display light 407 displays the color to determine whether it passes the test. If the battery plate In the case of heavier or lighter weight, the cross slot 402 will tilt, making it impossible to ensure that all lasers can pass through. At this time, the hexagonal rotating block 203 can be rotated to rotate the screw 202, thereby changing the position of the counterweight 206, thereby driving the indicator rod 210 to move along the scale 211, and the adjustment here cannot exceed the range allowed by the production standard, and the adjusted values ​​are all the maximum or minimum values ​​allowed by the standard, thereby changing the balance of the docking rod 103. If it still cannot pass the test after adjustment, it means that the battery plate does not meet the standard. If it can pass, it means that normal production can be carried out. Through this structure, the counterweight 206 can be adjusted according to the production standard while weighing, so that rapid detection can be carried out within the allowed range, greatly improving the detection efficiency of battery plate weight consistency.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
