Description

Technical Field

[0001] The invention belongs to the technical field of battery plate production weighing, and in particular relates to a battery plate weighing system and a weighing method. Background Art

[0002] In the production process of batteries, a very important step is to weigh the plates, that is, to weigh both the positive and negative plates in the battery.

[0003] Currently, most weighing operations still require manual labor to regularly weigh the plates. However, such traditional operations have low flexibility and poor maneuverability, which not only increases labor costs, but also poses a safety hazard due to the corrosive electrolyte on the plates. At the same time, the number and time of weighing cannot be well controlled, making it difficult to ensure good quality control of the product during the production process, affecting product performance and manufacturing costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a battery plate weighing system and weighing method. Through the coordinated control of a dual lifting mechanism and a displacement mechanism, unmanned transfer and weighing of the plates on a conveyor line are realized, completely avoiding contact between operators and corrosive electrolytes, significantly improving production safety, and solving the problems raised by the existing background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention provides a battery plate weighing system, comprising two lifting mechanisms arranged in a gap, wherein a displacement mechanism for controlling the transfer of the plate from one lifting mechanism to the other lifting mechanism is arranged between the two lifting mechanisms; the lifting mechanism comprises a lifting frame and a lifting cylinder connected to the bottom or side wall of the lifting frame, and the lifting frame is driven up and down by the lifting cylinder when in use; when in use, the plate is transported on a conveyor, and the two ends of the plate protrude from the two sides of the conveyor during transportation; the lifting frame comprises a U-shaped plate for the conveying surface of the conveyor to pass through, and the two ends of the U-shaped plate are respectively connected to a U-shaped connecting frame for avoiding the plate, and the side wall of one end of the U-shaped connecting frame is connected to an L-shaped plate for supporting the side walls at both ends of the plate; a weighing module is arranged on the displacement mechanism or the lifting mechanism; through the coordinated design of the double lifting mechanism and the displacement mechanism, the fully automatic transfer and weighing of the plate on the conveyor is realized, eliminating the risk of active material contamination caused by manual intervention.

[0007] Furthermore, the conveyor is a belt conveyor, a synchronous belt conveyor, or a chain conveyor; multiple options are available to meet the conveying requirements of plates of different sizes.

[0008] Furthermore, reinforcing ribs A are provided on both sides of the U-shaped connecting frame, and reinforcing ribs B are provided on the inner side of the L-shaped plate. The reinforcing ribs A and B respectively strengthen the structural rigidity of the U-shaped connecting frame and the L-shaped plate to prevent deformation when lifting heavy plates.

[0009] Furthermore, after the lifting cylinder is controlled to drive the lifting frame to complete the lifting, the two ends of the electrode plate transported on the conveyor pass through the U-shaped connecting frame during transportation; the displacement mechanism includes a guide rail arranged above the conveyor, and an electric slider is arranged on the guide rail, and one side of the electric slider is connected to a mounting plate, and the lower surface of the mounting plate is fixed with a motor whose output end passes through the mounting plate, and the output end of the motor is connected to the end of a swing arm, and the other end of the swing arm is connected to the support plate; after the lifting cylinder is controlled to drive the lifting frame to complete the lifting, the electric slider is controlled to drive the support plate to extend between the conveyor and the electrode plate; the weighing module is installed on the support plate; the electric slider and the motor-driven swing arm are combined to realize precise three-dimensional positioning of the support plate, and the weighing module is installed on the support plate to isolate the vibration interference of the conveyor.

[0010] Furthermore, the support plate is a rectangular plate, and upwardly protruding edges are respectively provided at both ends of the rectangular plate, and the convex edges form anti-slip edges to prevent the pole plate from sliding off during the rotation of the swing arm, thereby ensuring the safety of transfer.

[0011] Furthermore, the end of the lifting cylinder supports a weighing module connected to the side of the outer bottom of the lifting frame. The weighing module is directly integrated into the top of the lifting cylinder, which can monitor the load-bearing status of the lifting frame in real time and realize double-position redundant weighing verification; and it is convenient to weigh the electrode 200 when in use.

[0012] A battery plate weighing method comprises the following steps:

[0013] Step 1: First, control the lifting mechanism away from the discharge end of the conveyor to move upward to drive a plate on the conveyor to separate from its conveying surface;

[0014] Step 2: Control the electric slider to drive the support plate to extend between the conveyor and the electrode plate, and then control the lifting mechanism to move downward. At this time, the electrode plate is supported on the support plate;

[0015] Step 3: Control the lifting mechanism near the discharge end of the conveyor to move upward, and control the support plate with the electrode plate to be located between the two L-shaped plates under the action of the motor and the electric slider;

[0016] Step 4: Control the lifting mechanism near the discharge end of the conveyor to move upward to drive the plate to separate from the support plate. At this time, control the electric slider to move the support plate out from between the two L-shaped plates, and then control the lifting mechanism to move downward to place the plate on the conveying surface of the conveyor.

[0017] It also includes a controller, which is connected to the lifting cylinder, electric slider, and motor. The four-step control method uses two sets of lifting mechanisms to alternately move, completing dynamic weighing of the plate without stopping the conveyor, thereby improving efficiency.

[0018] Furthermore, the support surface of the L-shaped plate and the upper surface of the rectangular plate are both covered with a polyurethane buffer layer, which absorbs the contact impact between the support plate and the rectangular plate and the L-shaped plate, thereby preventing active materials from falling off at the edge of the plate.

[0019] The present invention has the following beneficial effects:

[0020] The present invention realizes unmanned transfer and weighing of electrode plates on the conveyor line through the coordinated control of the dual lifting mechanism and the displacement mechanism, completely avoiding the operator's contact with corrosive electrolyte and significantly improving production safety.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1-2 As shown, the present invention is a battery plate weighing system, including a conveyor 100 for conveying plates 200, wherein the conveyor 100 is a belt conveyor; and two lifting mechanisms are arranged at intervals along the conveying direction of the conveyor 100, and a displacement mechanism is arranged between the two lifting mechanisms. When in use, the displacement mechanism is used to transfer the plates on the lifting mechanism near the feeding end of the conveyor 100 to another lifting mechanism near the discharging end of the conveyor 100.

[0033] Specifically, the provided lifting mechanism includes a lifting frame 1 and a lifting cylinder connected to the outer bottom side of the bottom of the lifting frame 1. When in use, the lifting cylinder drives the lifting frame 1 to move up and down.

[0034] like Figure 3 The lifting frame 1 includes a U-shaped plate 11. When in use, the conveyor belt of the conveyor 100 passes through the U-shaped plate 11, and the two ends of the electrode plate 200 protrude from both sides of the conveyor 100. The two ends of the U-shaped plate 11 are respectively connected to a U-shaped connecting frame 12 for avoiding the electrode plate 200. The side wall of one end of the U-shaped connecting frame 12 is connected to an L-shaped plate 13 for supporting the side walls of the two ends of the electrode plate 200; after the lifting cylinder is controlled to drive the lifting frame 1 to complete the lifting, the two ends of the electrode plate 200 transported on the conveyor 100 pass through the U-shaped connecting frame 12 during transportation.

[0035] In order to facilitate weighing the electrode plate 200 , a weighing module is provided on the displacement mechanism or the lifting mechanism.

[0036] like Figure 1-2As shown, in order to facilitate the transfer of the electrode plate 200, the displacement mechanism provided by the present invention includes a guide rail 2 arranged above the conveyor 100, and an electric slider 21 is arranged on the guide rail 2. When in use, the moving direction of the electric slider 21 is the same as or opposite to the conveying direction of the conveyor 100, and a mounting plate 22 is connected to one side of the electric slider 21. A motor 23 with an output end passing through the mounting plate 22 is fixed to the lower surface of the mounting plate 22. The output end of the motor 23 is connected to the end of a swing arm 24, and the other end of the swing arm 24 is connected to the support plate 25.

[0037] That is, during use, after controlling the lifting cylinder to drive the lifting frame 1 to complete the lifting, the electric slider 21 can be controlled to drive the support plate 25 to extend between the conveyor 100 and the electrode plate 200, and then the lifting cylinder can be controlled to move again to place the electrode plate 200 on the lifting frame 1, or to push out the electrode plate 200 located on the lifting frame 1.

[0038] Specifically, a weighing module connected to the outer bottom side of the lifting frame 1 is supported at the end of the lifting cylinder; or a weighing module is installed on the supporting plate 25.

[0039] On the basis of the above, reinforcing ribs A14 are respectively provided on both sides of the U-shaped connecting frame 12 , and reinforcing ribs B15 are provided on the inner side of the L-shaped plate 13 .

[0040] In a specific embodiment, Figure 4 The support plate 25 is a rectangular plate 251 , and upwardly protruding ridges 252 are respectively provided at both ends of the rectangular plate 251 , and a polyurethane buffer strip is embedded in the top of the ridge 252 .

[0041] Example 2: Based on the battery plate weighing system provided in Example 1, the present invention further provides a battery plate weighing method, comprising the following steps:

[0042] Step 1: First, control the lifting mechanism away from the discharge end of the conveyor 100 to move upward to drive a plate 200 located on the conveyor 100 to separate from its conveying surface;

[0043] Step 2: Control the electric slider 21 to drive the support plate 25 to extend between the conveyor 100 and the electrode plate 200, and then control the lifting mechanism to move downward. At this time, the electrode plate 200 is supported on the support plate 25;

[0044] Step 3: Control the lifting mechanism near the discharge end of the conveyor 100 to move upward, and control the support plate 25 with the electrode plate 200 to be located between the two L-shaped plates 13 under the action of the motor 23 and the electric slider 21;

[0045] Step 4: Control the lifting mechanism near the discharge end of the conveyor 100 to move upward to drive the electrode plate 200 to separate from the support plate 25. At this time, control the electric slider 21 to move the support plate 25 out from between the two L-shaped plates 13, and then control the lifting mechanism to move downward to place the electrode plate 200 on the conveying surface of the conveyor 100.

[0046] By using the lifting mechanism and the displacement mechanism in conjunction with each other, the control plate 200 is removed from the conveyor belt and then weighed, and then the removed plate 200 is replaced to its original position.

[0047] The device further includes a controller, which is connected to the lifting cylinder, the electric slider 21 , and the motor 25 .
