Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lead-acid battery production, and particularly relates to a continuous sheet coating automatic weighing and inspecting device for lead-acid batteries. BACKGROUND

[0002] Lead-acid batteries are widely used because of high working voltage, wide use temperature, good high and low rate discharge performance, easy availability of raw materials and low price. As the main component of lead-acid batteries, the plate functions to store electric energy when the battery is charged and release electric energy when the battery is discharged, and can be repeatedly cycled, thereby constituting the chargeable and dischargeable function of the lead-acid battery. The plate manufacturing methods in the industry mainly include single sheet coating, continuous sheet coating and tube type lead paste injection, etc. In the production process of the battery, one very important process is to weigh the plate, that is, to weigh the positive and negative plates in the battery.

[0003] CN218121113U discloses an online weighing device for lead-acid battery plates, which comprises a support frame, an adsorption assembly, a moving assembly and a weighing assembly installed on the support frame; the adsorption assembly is installed above a conveying assembly for conveying the plates to be weighed by the support frame, and is used to adsorb the plates to be weighed; the weighing assembly is installed on one side of the conveying assembly, and is used to weigh the weight of the plates to be weighed; the moving assembly is used to drive the adsorption assembly to move the plates to be weighed back and forth between the conveying assembly and the weighing assembly. In this technical solution, the adsorption assembly and the moving assembly are controlled to put the plate from the weighing assembly onto the conveying assembly after the weighing is completed by the weighing assembly. Since the plates are conveyed on the conveying mechanism, the distance between the plates on the conveying mechanism is small, and the weighing requires a certain time. Therefore, it is not possible to take out a plate from the conveying mechanism, weigh it and then put it back to the original position, which easily causes the problem that the plate cannot be put back onto the conveying assembly after the weighing. SUMMARY

[0004] The purpose of the present application is to provide a continuous sheet coating automatic weighing and inspecting device for lead-acid batteries, which installs a rectangular mounting plate at the end of a robot arm, and respectively installs a grabbing structure at both ends of the rectangular mounting plate, so as to control the other grabbing structure to put a sheet into the empty position left by the conveying mechanism after the sheet is removed by the above-mentioned grabbing structure when the sheet is grabbed by one grabbing structure, thereby solving the problems of the prior art.

[0005] To solve the above technical problems, the present application is realized by the following technical solutions:

[0006] This invention relates to an automatic weighing and inspection device for continuous lead-acid battery coatings, comprising a conveying mechanism for transporting battery coatings, the conveying mechanism being located at the end of a continuous plate rolling and cutting device; two columns of battery coatings are transported on opposite sides of the conveying mechanism, and the two columns of battery coatings are respectively marked as the left column and the right column; a weighing mechanism for weighing the battery coatings is located on one side of the conveying mechanism; a robotic arm is located between the weighing mechanism and the conveying mechanism, the end of the robotic arm being connected to a rectangular mounting plate, and both ends of the rectangular mounting plate being respectively provided with gripping structures A for gripping the battery coatings; the robotic arm and gripping structures A constitute a gripping mechanism;

[0007] The automated weighing inspection method for continuous smears includes the following steps:

[0008] Step 1: Start the equipment and use the gripping mechanism to grab the battery coatings on the left column of the conveying mechanism and place them on the weighing mechanism;

[0009] Step 2: Use the gripping mechanism to grab the battery coatings on the right column of the conveying mechanism and place them on the weighing mechanism, while simultaneously grabbing the battery coatings on the left column of the weighing mechanism.

[0010] Step 3: Use the gripping mechanism to grab the battery coatings on the left column of the conveying mechanism and place them on the weighing mechanism;

[0011] When the battery coatings in the left column are placed on the weighing mechanism, the battery coatings in the right column located on the weighing mechanism are simultaneously grabbed.

[0012] In this process, after grabbing the battery coating in the left column and delaying for a time T, the battery coating in the left column grabbed by the grabbing mechanism in step 2 is placed onto the conveying mechanism.

[0013] Step 4: Use the gripping mechanism to grab the battery coatings on the right side of the conveying mechanism and place them onto the weighing mechanism.

[0014] When the battery coatings in the right column are placed on the weighing mechanism, the battery coatings in the left column located on the weighing mechanism are simultaneously grabbed.

[0015] In this process, after grabbing the battery coating in the right column and delaying for a time T, the battery coating in the right column grabbed in step 3 on the grabbing mechanism is placed onto the conveying mechanism.

[0016] Step 5: Repeat steps 3 and 4.

[0017] Furthermore, the weighing mechanism includes a base plate, on which a weighing platform, a first support platform, and a second support platform are provided.

[0018] Furthermore, in use, the first support platform is used to place the battery coatings in the left column, and the second support platform is used to place the battery coatings in the right column.

[0019] Furthermore, it also includes a displacement mechanism for gripping and placing battery coatings located on the weighing platform onto the first support platform and the second support platform; the displacement mechanism includes a slide rail arranged horizontally and parallel to the conveying direction of the conveying mechanism, an electric slide block is fitted on the slide rail, a linear module A arranged horizontally and perpendicular to the conveying direction of the conveying mechanism is connected to the upper surface of the electric slide block, a linear module B arranged vertically and perpendicular to the conveying direction of the conveying mechanism is connected to the slider of the linear module A, an L-shaped mounting plate is connected to the slider of the linear module B, a telescopic mechanism that extends vertically is connected to the L-shaped mounting plate, a crossbar arranged horizontally and perpendicular to the conveying direction of the conveying mechanism is connected to the end of the telescopic mechanism, and a gripping structure B for battery coatings is connected to the end of the crossbar.

[0022] Furthermore, the distance between the two gripping structures A on the rectangular mounting plate is L. At this time, the controller starts timing and simultaneously obtains the conveying speed V of the conveying mechanism. Then, in steps 3 and 4, after gripping the battery coating on the conveying mechanism, the original battery coating on the gripping mechanism is placed onto the conveying mechanism after a delay of t; t = L / V.

The invention is achieved by installing a rectangular mounting plate at the end of the robot arm and assembling a gripping structure at each end of the rectangular mounting plate.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] Please see Figure 1As shown, the present invention is an automatic weighing and inspection device for continuous coating of lead-acid batteries, including a conveying mechanism 1 for conveying battery coatings 10. The conveying mechanism 1 is located at the end of a continuous plate rolling cutter, and the cut battery coatings 10 are divided into two columns and arranged on the conveying mechanism 1 under the action of continuous plate rolling cutter. The two columns of battery coatings 10 are respectively conveyed on both sides of the conveying mechanism 1, and the two columns of battery coatings 10 are marked as left column and right column, respectively. A weighing mechanism 2 and a robot arm 3 are arranged on one side of the conveying mechanism 1. The end of the robot arm 3 is equipped with a gripping mechanism. Under the action of the robot arm 3, the gripping mechanism facilitates the gripping of the battery coatings 10 on the conveying mechanism 1 and placing them on the weighing mechanism 2, and facilitates the gripping of the battery coatings 10 on the weighing mechanism 2 and placing them on the conveying mechanism 1.

[0034] Specifically, such as Figure 2 The gripping mechanism includes a rectangular mounting plate 30 installed at the end of the robot arm 3, and gripping structures A31 for gripping the battery coating 10 are respectively provided at both ends of the rectangular mounting plate 30; for example Figure 4 The weighing mechanism 2 includes a base plate 20, on which a weighing platform 21, a first support platform 22, and a second support platform 23 are provided.

[0035] Based on the above structural design, the automatic weighing and inspection method for continuous smears includes the following steps:

[0036] Step 1: Start the equipment and use the gripping mechanism to grab the battery coating 10 located on the left column of the conveying mechanism 1 and place it on the weighing mechanism 2.

[0037] Step 2: Use the gripping mechanism to grip the battery coating 10 on the right column of the conveying mechanism 1 and place it on the weighing mechanism 2, while simultaneously gripping the battery coating 10 on the left column of the weighing mechanism 2.

[0038] Step 3: Use the gripping mechanism to grip the battery coating 10 in the left column on the conveying mechanism 1 and place it on the weighing mechanism 2; while placing the battery coating 10 in the left column on the weighing mechanism 2, simultaneously grip the battery coating 10 in the right column on the weighing mechanism 2; after a delay of T after gripping the battery coating 10 in the left column, place the battery coating 10 in the left column gripped in step 2 on the conveying mechanism 1.

[0039] Step 4: Use the gripping mechanism to grip the right column of battery coatings 10 located on the conveying mechanism 1 and place them on the weighing mechanism 2. While placing the right column of battery coatings 10 on the weighing mechanism 2, simultaneously grip the left column of battery coatings 10 located on the weighing mechanism 2. After a delay of T after gripping the right column of battery coatings 10, place the right column of battery coatings 10 gripped in step 3 on the gripping mechanism onto the conveying mechanism 1.

[0040] Step 5: Repeat steps 3 and 4.

[0041] In steps 3 and 4 above, after one battery coating 10 is picked up from the conveying mechanism 1, another battery coating 10 that has been weighed and detected is placed into the gap left after the battery coating 10 is picked up.

[0042] In the above, for convenience and perfection, another battery coating 10 is placed into the gap left after the battery coating 10 is grabbed. At this time, the distance between the two gripping structures A31 on the rectangular mounting plate 30 needs to be measured as L. At this time, the controller starts timing and simultaneously obtains the conveying speed V of the conveying mechanism 1. Then, in steps 3 and 4, after grabbing the battery coating 10 located on the conveying mechanism 1, the original battery coating 10 on the gripping mechanism is placed onto the conveying mechanism 1 after a delay of t; t = L / V.

[0043] Meanwhile, in this invention, after the weighing platform 21 is used to test a battery coating 10, the battery coating 10 located on the weighing platform 21 needs to be moved and placed on the first support platform 22 or the second support platform 23 after the test is completed; that is, when the battery coating 10 on the weighing platform 21 is the battery coating 10 in the left column, the battery coating 10 is controlled to be placed on the first support platform 22; when the battery coating 10 on the weighing platform 21 is the battery coating 10 in the right column, the battery coating 10 is controlled to be placed on the second support platform 23.

[0044] To facilitate the gripping and moving of the battery coating 10 from the weighing platform 21 to the first support platform 22 or the second support platform 23, the present invention also includes a displacement mechanism, such as... Figure 1 The displacement mechanism includes a slide rail 4 arranged horizontally and parallel to the conveying direction of the conveying mechanism 1. An electric slide block 41 is fitted on the slide rail 4. A linear module A42 arranged horizontally and perpendicular to the conveying direction of the conveying mechanism 1 is connected to the upper surface of the electric slide block 41. A linear module B43 arranged vertically and perpendicular to the conveying direction of the conveying mechanism 1 is connected to the slider of the linear module A42. An L-shaped mounting plate 44 is connected to the slider of the linear module B43. A telescopic mechanism 45 that extends vertically is connected to the L-shaped mounting plate 44. A crossbar 46 that extends horizontally and perpendicular to the conveying direction of the conveying mechanism 1 is connected to the end of the telescopic mechanism 45. A gripping structure B47 for the battery coating 10 is connected to the end of the crossbar 46.

[0045] like Figure 3The gripping structures A31 and B47 have the same structure, both including a telescopic cylinder 310. The end of the telescopic cylinder 310 is connected to a U-shaped frame 311, and the end of the U-shaped frame 311 is connected to a base plate A312. The bottom side of the base plate A312 is connected to a base plate B314 via a spring 313. The bottom side of the base plate B314 is provided with at least two vacuum suction cups. A guide rod 315 is provided on the base plate B314, which moves through the base plate A312. The end of the guide rod 315 is threadedly connected to a threaded sleeve 316.

[0046] When the gripping mechanism grips the battery coating 10 on the conveying mechanism 1, the length direction of the rectangular mounting plate 30 is the same as the conveying direction of the conveying mechanism 1; when the gripping mechanism grips the battery coating 10 located on the weighing mechanism 2, the length direction of the rectangular mounting plate 30 is perpendicular to the conveying direction of the conveying mechanism 1.
