Description

Technical Field

[0001] The present invention relates to the technical field of battery cover feeding and conveying, and in particular to a stacking and feeding mechanism for battery covers of new energy electric vehicles. Background Art

[0002] With the rapid global development of the new energy vehicle industry, demand for new energy batteries is increasing year by year. The manufacturing efficiency of new energy battery covers directly determines their production output. The efficiency and stability of the raw sheet material loading process are key to increasing production. To this end, we are utilizing a stacking system that stacks raw sheet materials within a stacker to improve efficiency, and employing an XZ-axis transfer assembly to control a pneumatic reclaimer to extract the raw sheet materials for improved stability.

[0003] Since the raw material plates are allowed to have thickness errors during the production process, for example, a plate with a thickness of 1 cm itself can be used for subsequent production with a thickness of 0.9 cm-1.1 cm. A large number of raw material plates will be stacked in the stacking car. As the allowable errors accumulate, the number of plates in a car will appear to be a few more or a few less. If the XZ-axis transfer assembly descends the same distance according to the preset value, when the thickness of the raw material plates is greater than 1 cm, the error accumulation will suddenly cause the elastic vacuum suction head to fail to fit the raw material plate and cause empty suction, resulting in the raw material plate not being sucked onto the centering device, causing a chain reaction. When the thickness is less than 1 cm, the error accumulation will cause the elastic vacuum suction head to be gradually compressed and deformed, affecting the life of the elastic vacuum suction head.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention

[0005] The purpose of the present invention is to design a battery cover stacking and loading mechanism that can eliminate cumulative errors and prevent the errors from accumulating to the point of causing empty suction and multiple deformation of the elastic vacuum suction head, so as to solve the above-mentioned shortcomings in the technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy electric vehicle battery cover stacking and feeding mechanism, comprising a feeding frame, an XZ-axis transfer assembly is installed on the feeding frame, a pneumatic feeding device is installed at the end of the output shaft of the XZ-axis transfer assembly, a centering frame is provided in the middle part below the feeding frame, a centering device is installed on the centering frame, both sides of the centering frame are provided with stacking carts whose positions remain unchanged during loading, and the stacking carts have stacked battery cover raw material plates, the pneumatic feeding device comprises a mounting frame, a plurality of elastic vacuum suction heads are fixedly installed on the mounting frame, and the pneumatic feeding device also includes A pressure assembly fixedly mounted on a mounting frame that can slide vertically and detect pressure, a connector fixedly mounted on the mounting frame, and a contact sensor fixedly mounted on the end of the connector. The contact sensor model is GT2-H12F. The middle portion of the stacking trolley has a through hole smaller than the raw material plate. The bottom of the stacking trolley is provided with a vertical jacking device. When the output shaft of the vertical jacking device is extended, the raw material plate is driven to rise. Only after the elastic vacuum suction head and the pressure assembly are in contact with the raw material plate can the contact sensor contact the top of the stacking trolley and control the XZ-axis transplanting assembly to stop descending.

[0007] After the raw material plate is pushed up to a standard height by the vertical lifting device, the contact sensor drops vertically again until it contacts the top of the stacking car. At this time, the pressure component dynamically adjusts the height of the raw material plate to be pushed up next time according to the deviation of the pressure value.

[0008] Preferably, when the pressure assembly and the elastic vacuum suction head are not in contact with the raw material plate, the height of the bottom of the pressure assembly and the elastic vacuum suction head is lower than the height of the contact sensor.

[0009] Preferably, when the raw material plates are stacked in the stacking vehicle in an initial state, the top surface of the uppermost raw material plate is higher than the top surface of the stacking vehicle, and the top surface of a raw material plate below the uppermost raw material plate is lower than the top surface of the stacking vehicle.

[0010] Preferably, in the initial state, the thickness error of the top raw material plate stacked in the stacking vehicle is 0.1-0.5 times of the maximum allowable error.

[0011] Preferably, the pressure assembly is not located directly above the vertical jacking device.

[0012] Preferably, the pressure assembly includes a hollow tube fixedly connected to the mounting frame, a slide rod vertically slidably installed in the hollow tube, a pressure sensor fixedly installed at the bottom end of the slide rod, and a spring fixedly installed between the hollow tube and the slide rod. The model of the pressure sensor is: MEAS M5600.

[0013] Preferably, a fence assembly is installed at the bottom of the loading frame, and the XZ-axis transplanting assembly, the centering frame, the stacking car and the vertical jacking device are all located inside the fence assembly.

[0014] Preferably, the top of the stacking vehicle is a layer of rubber material component.

[0015] Preferably, the thickness of the raw material plates in the stacking vehicle is within a maximum allowable error value.

[0016] Preferably, the vertical lifting device includes an electric telescopic rod fixedly connected to the fence assembly, and a top plate fixedly installed at the output end of the electric telescopic rod.

[0017] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0018] 1. The present invention uses a vertical lifting device to push the N+2th raw material plate to the thickness of the Nth raw material plate, thereby eliminating the thickness error caused by the Nth raw material plate, thereby re-accumulating the errors of the raw material plates, and preventing the thickness errors of the raw material plates from accumulating too much, resulting in the elastic vacuum suction head suddenly losing contact with the raw material plate, causing empty suction, or severe pressure on the elastic vacuum suction head causing deformation;

[0019] 2. The present invention calculates the thickness of the Nth raw material plate through the cooperation of a pressure sensor, a contact sensor and a vertical lifting device, thereby changing the vertical lifting device to push all raw material plates in the stacking vehicle to rise. The structure is simple and easy to upgrade and improve.

[0020] 3. At the same time, when all the raw material plates in the stacking car are taken away, the contact sensor will contact the top of the stacking car to transmit a signal, while the pressure sensor has no object in contact with it, thereby automatically judging that all the raw material plates in the stacking car have been taken away. The elastic vacuum suction head will not suck the bottom of the inner cavity of the stacking car, and there is no need to use other equipment to judge whether all the raw material plates in the stacking car have been taken away.

[0031] In order to help those skilled in the art better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] The present invention provides Figure 1-7The stacking and loading mechanism of the battery cover of a new energy electric vehicle shown in the figure comprises a loading frame 1, an XZ-axis transfer assembly 2 installed on the loading frame 1, a pneumatic material taking device 3 installed at the end of the output shaft of the XZ-axis transfer assembly 2, a centering frame 4 arranged in the middle below the loading frame 1, a centering device 5 installed on the centering frame 4, and a stacking car 6 with battery cover raw material plates 7 stacked inside. There are two stacking cars 6, which are respectively located at the bottom of both sides of the loading frame 1. When the stacking cars 6 are located on both sides of the centering frame 4 for loading, , is in a predetermined position and cannot be moved, and we have installed a fence assembly 10 outside these devices for personnel protection. The pneumatic material removal device 3 itself includes a mounting frame 3a, and multiple elastic vacuum suction heads 3b installed on the mounting frame 3a. When the elastic vacuum suction head 3b contacts the top surface of the raw material plate 7, the vacuum pump is controlled to make the elastic vacuum suction head 3b generate suction, which can move the raw material plate 7. Through the cooperation of the XZ axis transfer assembly 2, the raw material plate 7 can be moved into the centering device 5, and the material can be loaded after centering;

[0034] Since the raw material plates 7 are allowed to have thickness errors during the production process, for example, a plate with a thickness of 1 cm can be used for subsequent production with a thickness of 0.9 cm to 1.1 cm, and a large number of raw material plates 7 will be stacked in the stacking car 6. As the allowable errors accumulate, the number of plates in one car may be a few more or a few less. If the XZ-axis transfer assembly 2 descends the same distance according to the predetermined value, when the thickness of all the raw material plates 7 is greater than 1 cm, the elastic vacuum suction head 3 b may suddenly fail to fit the raw material plates 7, resulting in the failure to suck the raw material plates 7 onto the centering device 5, causing a chain reaction.

[0035] To this end, we fixed a pressure assembly 3c on the mounting frame 3a that can slide vertically and detect pressure values. The pressure assembly 3c includes a hollow tube 3c1 fixed on the mounting frame 3a, a slide rod 3c2 that slides vertically in the hollow tube 3c1, a pressure sensor 3c3 fixedly installed at the bottom end of the slide rod 3c2, and a spring 3c4 fixedly installed between the hollow tube 3c1 and the slide rod 3c2. At the same time, we fixed a connecting piece 3d on the mounting frame 3a, and fixedly installed a contact sensor 3e at the end of the connecting piece 3d, and let the contact sensor 3e be located just above the side wall of the stacking car 6, so that the contact sensor 3e can contact the top of the stacking car 6 when it descends, thereby controlling the XZ-axis transplanting assembly 2 to no longer descend. At the same time, we opened a through hole 8 in the middle of the stacking car 6, and installed a vertical jacking device 9 consisting of an electric telescopic rod 9a and a top plate 9b on the fence assembly 10. When the output shaft of the electric telescopic rod 9a is extended, it pushes the raw material plate 7 up through the top plate 9b;

[0036] When using this device, first stack the raw material plates 7 directly into the stacking cart 6 until the top surface of the uppermost raw material is higher than the top surface of the stacking cart 6, but the top surface of the second highest raw material plate 7 is lower than the top surface of the stacking cart 6. At the same time, we'd better replace the uppermost raw material plate 7 with a raw material plate 7 with a thickness error less than 0.1-0.5 times the maximum error, such as 0.95-1.05cm thick. At the beginning, the XZ-axis transfer component 2 drives the pneumatic material picking device 3 to descend, and the pressure component 3c and the elastic vacuum suction head 3b will first contact the uppermost raw material plate 7, and then the contact sensor 3e will contact the top surface of the stacking cart 6. At this time, the contact sensor 3e transmits a signal to the processor, and the processor controls the XZ-axis transfer component 2 to stop descending. At this time, the pressure sensor 3c3 will push the slide bar 3c2 to compress the spring 3c4, pressing The force sensor 3c3 will display the pressure generated when it contacts the raw material sheet 7 and record this pressure value A. Because the height to which the contact sensor descends is fixed, the greater the pressure value detected by the pressure sensor 3c3, the higher the top surface of the raw material sheet 7 in contact with the pressure sensor 3c3 is than the top surface of the stacking cart 6. Therefore, the distance between the top surface of the raw material sheet 7 in contact with the pressure sensor 3c3 and the top surface of the stacking cart 6 can be calculated based on the pressure value. For example, if it is determined that the distance between the top surface of the first raw material sheet 7 and the top surface of the stacking cart 6 is 0.45 cm, then according to the existing technology, the elastic vacuum suction head 3b generates suction to move the raw material sheet 7 to the centering device 5 in conjunction with the XZ-axis transfer assembly 2. Here, in order to protect the contact sensor, a layer of rubber material component is provided on the top of the stacking cart 6;

[0037] Then the electric telescopic rod 9a passes through the top plate 9b and the through hole 8 to lift the raw material plate 7 in the stacking car 6 by 1 cm, and then the XZ axis transfer assembly 2 drives the pneumatic material removal device 3 to descend to the stacking car 6, as shown in FIG. Figure 7As shown, the second raw material plate 7 will record the pressure value B after contacting with the pressure sensor 3c3. The pressure value can be used to determine that the distance between the top surface of the second raw material plate 7 and the top surface of the stacking cart 6 is, for example, 0.40 cm. 0.40 cm is 0.05 cm smaller than 0.45 cm. Assuming that the thickness of the first raw material plate 7 is X, then 1-(X-0.45)=0.4, X=1.05. After the thickness Y of the second raw material plate 7 is unknown and is taken away, the vertical lifting device 9 will move the stacking cart 6 again. The raw material plate 7 in 6 is lifted up to a height of 1.05 cm, eliminating the error of the first raw material plate 7. After the top surface of the third raw material plate 7 contacts the pressure sensor 3c3, the pressure value C will be recorded. Assuming that it is inferred to be 0.35 cm higher than the top surface of the stacking car 6, 1.05-(Y-0.4)=0.35, Y=1.1 cm, the vertical lifting device 9 will then lift the fourth raw material plate 7 in the stacking car 6 to a height of 1.1 cm, eliminating the error of the second raw material plate 7. The third raw material plate 7 is taken away because its thickness Z is unknown. At this time, after the fourth raw material plate 7 contacts the pressure sensor 3c3, it is inferred that the fourth raw material plate 7 is 0.5 cm higher than the top surface of the stacking cart 6, then 1.1-(Z-0.35)=0.5, Z=0.95 cm, and then the vertical lifting device 9 lifts the fifth raw material plate 7 in the stacking cart 6 to a height of 0.95 cm. Similarly, the thickness error caused by the Nth raw material plate 7 will be manifested in the pressure value generated when the N+1th raw material plate 7 contacts the pressure sensor 3c3. The thickness of the Nth raw material plate 7 is inferred, so that the height of the N+2th raw material plate 7 lifted by the vertical lifting device 9 is the thickness of the Nth raw material plate 7, thereby eliminating the thickness error caused by the Nth raw material plate 7, thereby re-accumulating the error of the raw material plate 7, preventing the thickness error of the raw material plate 7 from accumulating too large, and ensuring that each raw material plate 7 can normally contact the elastic vacuum suction head 3b, and no empty suction or serious extrusion will occur;

[0038] When the contact sensor 3e contacts the top of the stacking cart 6, but the pressure sensor 3c3 does not generate a pressure value, it means that the raw material plates 7 in the stacking cart 6 have been taken out. The XZ-axis transfer assembly 2 then moves the pneumatic material taking device 3 to another stacking cart 6 to absorb the raw material plates 7, and manually restacks the empty stacking cart 6 with the raw material plates 7.

[0039] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are illustrative only.
