Description

Technical Field

[0001] The utility model belongs to the technical field of battery plate production, and relates to the detection of the weight of plate lead paste. Specifically, it is a lead paste weight sampling inspection mechanism for a battery plate production line. Background Technique

[0002] At present, the manufactured battery plates usually need to be subjected to quality inspections in aspects such as size, weight, and active substance content to ensure compliance with standards. Among them, in terms of weight, the industry generally requires that the weight difference of the plates produced in the same batch should be within 0.3%. Otherwise, they are unqualified products and need to be recycled and reused.

[0003] When producing battery plates, the gap size between the paste applicator hopper and the plate grid roller in the production line is a key factor affecting the plate weight. In the prior art, the gap adjustment between the paste applicator hopper and the roller is generally completed by workers according to the quality inspection results at the rear end of the production line. That is, after the plate assembly is completed, a quality inspection is carried out at the rear end. If it is detected that the plate quality does not meet the standard (it should be noted here that the "plate quality not meeting the standard" mentioned here and below means that the weight difference between two plates in the same batch exceeds 0.3%), then the gap between the paste applicator hopper and the roller needs to be adjusted to optimize the weight of the plates produced subsequently and improve the weight consistency of the plates in the same batch.

[0004] However, the above method has a processing delay, that is, a large amount of waste is generated in the production line when it is found that the plate weight does not meet the standard. Specifically, after the active substance (such as lead oxide) is evenly coated on the surface of the plate grid of the roller by the paste applicator hopper in the paste application process, it needs to go through the slicing process and the drying process first, and then it can be judged whether the plate weight meets the standard in the quality inspection at the rear end. If it is detected at the rear end that the plate weight does not meet the standard, it means that all semi-finished products on this section of the production line from the paste application process to the drying process are unqualified products, resulting in a large amount of waste.

[0005] When recycling and reusing the waste, the separation of the lead paste from the plate grid is not only time-consuming and laborious, but also causes waste of production man-hours and some resources, affecting the production efficiency of the production line.

[0006] In view of the defects of the above method, some enterprises choose to add an artificial sampling inspection and weighing link, that is, the weight of the plates is sampled and inspected manually after the slicing process is completed, and the gap between the paste applicator hopper and the roller is adjusted in a timely manner according to the sampling inspection results. Although this avoids the problem of "processing delay" to a certain extent, the manual sampling inspection increases the workload, and at the same time, it is impossible to ensure the rationality of sampling, resulting in the problem of poor weight consistency of the plates in the same batch still existing. Summary of the Utility Model

[0007] The utility model provides a lead paste weight sampling and inspection mechanism for a storage battery plate production line, which can monitor the weight of the plates on the production line in real time, provide a scientific reference for the gap adjustment between the paste applicator and the roller, and further achieve the purpose of improving the weight consistency of the plates in the same batch.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows: a lead paste weight sampling and inspection mechanism for a storage battery plate production line includes a weighing component arranged on one side of the production line, and also includes a suction nozzle component assembled on the production line through a three-axis manipulator to reciprocate between the weighing component and the production line for plate transfer.

[0009] As a limitation of the utility model, the suction nozzle component includes a mounting bracket connected to the output end of the three-axis manipulator and a first suction nozzle and a second suction nozzle assembled on the mounting bracket;

[0010] The first suction nozzle and the second suction nozzle are arranged along the conveying direction of the production line.

[0011] As a further limitation of the utility model, it also includes a counting sensor arranged above the production line and at the front end of the suction nozzle component.

[0012] As another limitation of the utility model, the weighing component includes a base arranged on one side of the production line, a linear actuator fixed on the base with its output end vertically upward, a receiving grid assembled on the output end of the linear actuator to be able to lift and lower, and a weighing sensor fixed on the base with its weighing table located directly below the receiving grid;

[0013] A receiving groove is provided at the top of the weighing table of the weighing sensor to enable the receiving grid to descend below the working surface of the weighing table.

[0014] As a further limitation of the utility model, it also includes a placement table fixed on the base of the weighing component and located on one side of the weighing sensor.

[0015] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects obtained by the utility model are as follows:

[0016] (1) The utility model realizes the automatic monitoring of the plate weight on the storage battery plate production line. Compared with the existing manual sampling and weighing method, it can reduce the manual error rate, improve the work efficiency synchronously, and reduce the labor cost. Applying the utility model between the slicing process and the drying process on the production line can provide a more scientific reference basis for the gap adjustment between the front-end paste applicator and the roller, so that whether manually adjusting the gap between the paste applicator and the roller or automatically adjusting the gap between the paste applicator and the roller with the help of relevant control equipment, the weight consistency of the plates in the same batch can be effectively improved, thereby ensuring the product quality.

[0017] (2) In the present invention, the counting sensor disposed at the front end of the nozzle assembly is used to count the number of electrodes on the production line so that the sampling frequency can be reasonably executed according to the statistical results.

[0018] (3) The material receiving grid set in the weighing assembly of the utility model and controlled by the linear drive for lifting and lowering is used to perform the material receiving / feeding action, which can prevent the suction nozzle assembly controlled by the three-axis manipulator from directly contacting the weighing sensor and causing damage to the weighing sensor. The setting of the material receiving grid in the utility model can effectively extend the service life of the weighing sensor.

[0019] (4) When the equipment is temporarily shut down, the storage table set on one side of the weighing sensor can be used to temporarily place samples sucked by the nozzle assembly or samples that have been weighed on the weighing sensor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0027] Embodiment A lead paste weight sampling mechanism for a battery plate production line

[0028] like Figure 1As shown in the figure, this embodiment includes a sampling component and a weighing component that cooperate with each other to perform sampling and weighing on the plates 12 on the battery plate production line 13.

[0029] The sampling component is used to grab a single plate 12 on the production line as the (n + 1)-th sampling sample provided to the weighing component, and at the same time send the n-th sampling sample back to the production line, where n ≥ 0. As Figure 2 shown, the sampling component includes a three-axis manipulator 1 and a suction nozzle assembly assembled on the three-axis manipulator 1. Among them, the three-axis manipulator 1 adopts an existing structure. When applying this embodiment, as Figure 1 shown, the three-axis manipulator 1 is assembled at the front end of the drying oven 14 in the battery plate production line 13. The suction nozzle assembly includes a mounting frame 2 and a first suction nozzle 3 and a second suction nozzle 4 assembled at both ends of the mounting frame 2. The mounting frame 2 is detachably connected to the output end of the three-axis manipulator 1 through multiple sets of bolts and nuts. When applying this embodiment on the battery plate production line 13, the first suction nozzle 3 and the second suction nozzle 4 are arranged front and back along the conveying direction of the production line. For specific reference, Figure 1 .

[0030] Under the control of the three-axis manipulator 1, the first suction nozzle 3 and the second suction nozzle 4 reciprocate between the weighing component and the battery plate production line 13 to transfer the plates 12.

[0031] It should be noted that in this embodiment, "front end" and "rear end" are defined in sequence along the conveying direction of the battery plate production line 13. For specific reference, Figure 1 the front and rear marked in

[0032] The weighing component is used to accurately weigh the weight of the sampling sample. As Figure 1 shown, the weighing component is integrally arranged on one side of the battery plate production line 13, and includes a base 5, a linear drive 6, a receiving grid 7, a weighing sensor 8, and a placing table 9. The base 5 is fixedly arranged on one side of the battery plate production line 13; the linear drive 6 is fixedly arranged on the base 5 and the output end is vertically upward. The linear drive 6 in this embodiment is a cylinder. Of course, according to the situation, a linear drive 6 with other structures such as a linear motor or an oil cylinder can also be selected; as Figure 3 and Figure 4 shown, the receiving grid 7 includes a connecting plate and a plurality of round rods arranged at intervals on the connecting plate. Among them, the connecting plate is fixedly arranged on the output end of the linear drive 6, and the receiving grid 7 can be lifted and lowered under the control of the linear drive 6; the weighing sensor 8 is fixedly arranged on the base 5, directly below the receiving grid 7; the placing table 9 is fixedly arranged on the base 5, on one side of the weighing sensor 8.

[0033] Further, a plurality of receiving grooves 10 are provided at the top of the weighing platform of the load cell 8, and the receiving grooves 10 correspond one-to-one with the positions of the round rods of the material receiving grid 7. When the linear actuator 6 controls the material receiving grid 7 to descend, the round rods of the material receiving grid 7 can enter the receiving grooves 10 of the load cell 8, so that the entire material receiving grid 7 is located below the working surface of the load cell 8.

[0034] In order to count the number of plates 12 on the storage battery plate production line 13, a counting sensor 11 is further provided above the production line and at the front end of the suction nozzle assembly in this embodiment. Usually, two plates 12 are conveyed side by side on the production line. Therefore, two counting sensors 11 are provided in this embodiment, corresponding to one plate 12 respectively.

[0035] When applied to the storage battery plate production line 13, this embodiment is installed between the slicing process and the drying process, specifically as Figure 1 shown. Moreover, this embodiment works under the control of the PLC controller, specifically as follows:

[0036] First, it is necessary to preset the sampling frequency. Generally, sampling and weighing are performed every 30 or 50 pieces, that is, according to the counting result of the counting sensor 11, the PLC controller controls the corresponding structure to perform actions. During sampling and weighing, first, the three-axis manipulator 1 controls the first suction cup to move above the first plate 12 to be grabbed, and grabs the plate 12 through the first suction cup; then, the three-axis manipulator 1 controls the first suction cup to move above the material receiving grid 7. At the same time, the material receiving grid 7 rises under the control of the linear actuator 6; after the first suction cup places the first plate 12 on the material receiving grid 7, the material receiving grid 7 descends below the working surface of the load cell 8 under the control of the linear actuator 6, and the first plate 12 is received by the working surface of the load cell 8 for weighing. After weighing is completed, the material receiving grid 7 rises under the control of the linear actuator 6 to re-lift the first plate 12;

[0037] The three-axis manipulator 1 controls the first suction cup to move above the production line again to grab the second plate 12; when the first suction cup grabs the second plate 12, the three-axis manipulator 1 first controls the second suction cup to move above the material receiving grid 7, grabs the first plate 12 with the second suction cup, and then the three-axis manipulator 1 controls the first suction cup to move above the material receiving grid 7 to put down the second plate 12 for weighing. After weighing is completed, the material receiving grid 7 rises under the control of the linear actuator 6 to re-lift the second plate 12;

[0038] The three-axis manipulator 1 controls the first suction cup to move above the production line again and grasp the third electrode plate 12. After the first suction cup grasps the third electrode plate 12, the three-axis manipulator 1 controls the second suction cup to move to the position on the production line where the third electrode plate 12 was originally placed, put down the first electrode plate 12, and then control the second suction cup to move above the receiving grid 7. After using the second suction cup to grasp the second electrode plate 12, the three-axis manipulator 1 controls the first suction cup to move above the receiving grid 7 to put down the third electrode plate 12 for weighing...

[0039] If it is necessary to temporarily stop the machine during operation, the electrode plate 12 grasped by the first suction cup or the second suction cup can be temporarily placed on the storage table 9 on one side.

[0040] According to the inspection and weighing results, the gap between the paste applicator and the roller is adjusted.

[0041] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
