Description

Technical Field

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

[0002] With the rapid development of the new energy vehicle industry globally, the demand for new energy batteries has been increasing year by year. The manufacturing efficiency of new energy battery covers directly determines the output of new energy batteries. The efficiency and stability of the feeding process of its raw material sheets are the key to improving the output of new energy battery covers. Therefore, everyone uses the method of stacking raw material sheets in a stacking vehicle to improve efficiency, and uses an XZ-axis transplanting component to control a pneumatic material-taking device to suck the raw material sheets to improve stability.

[0003] Since there is an allowable thickness error for raw material sheets during the production process. For example, for a sheet that is 1 cm thick itself, raw material sheets with a thickness ranging from 0.9 cm to 1.1 cm are allowed for subsequent production. And a relatively large number of raw material sheets will be stacked in the stacking vehicle. With the accumulation of each allowable error, the number of sheets in a vehicle may be a few more or a few less. If the XZ-axis transplanting component descends the same distance according to a predetermined value, when the thickness of all raw material sheets is greater than 1 cm, the error accumulation may suddenly cause the elastic vacuum suction head not to fit with the raw material sheet and result in air suction, causing the raw material sheet not to be sucked onto the centering device, leading to a chain reaction. When the thickness is less than 1 cm, the error accumulation will cause the elastic vacuum suction head to be gradually deformed, affecting the service life of the elastic vacuum suction head.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0005] The object of the present invention is to design a stacking and loading mechanism for battery covers that can eliminate cumulative errors and prevent the errors from accumulating to cause air suction and excessive deformation of the elastic vacuum suction head, so as to solve the above deficiencies in the technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a stacking and loading mechanism for a new energy electric vehicle battery cover, including a loading frame, an XZ-axis transplanting component is installed on the loading frame, a pneumatic material taking device is installed at the end of the output shaft of the XZ-axis transplanting component, a centering frame body is provided in the middle below the loading frame, a centering device is installed on the centering frame body, stacking carts with fixed positions during loading are provided on both sides of the centering frame body, and stacked battery cover raw material plates are provided in the stacking carts. The pneumatic material taking device includes a mounting frame, and a plurality of elastic vacuum suction heads are fixedly installed on the mounting frame. The pneumatic material taking device further includes a pressure component fixedly installed on the mounting frame that can slide vertically and detect pressure, a connecting member fixedly installed on the mounting frame, and a contact sensor fixedly installed at the end of the connecting member. The model of the contact sensor is: GT2-H12F. A through hole smaller than the raw material plate is provided in the middle of the stacking cart. A vertical lifting device is provided at the bottom of the stacking cart. When the output shaft of the vertical lifting device extends, it drives the raw material plate to rise. After the elastic vacuum suction head and the pressure component jointly contact the raw material plate, the contact sensor can contact the top of the stacking cart, and the XZ-axis transplanting component is controlled to stop descending;

[0007] After the vertical lifting device pushes the raw material plate to rise by a standard height, the contact sensor descends vertically again to contact the top of the stacking cart. At this time, the pressure component dynamically adjusts the height of the next push of the raw material plate to rise according to the deviation of the pressure value.

[0008] Preferably, when the pressure component and the elastic vacuum suction head do not contact the raw material plate, the heights of the bottoms of the pressure component and the elastic vacuum suction head are lower than the height of the contact sensor.

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

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

[0011] Preferably, the pressure component is not directly above the vertical lifting device.

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

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

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

[0015] Preferably, the thickness of the raw material plates in the stacking vehicle is within the thickness of the 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 as follows:

[0018] 1. In the present invention, the vertical lifting device pushes the (N + 3)-th raw material plate to rise by the thickness of the N-th raw material plate, which can eliminate the thickness error brought by the N-th raw material plate, thereby re-accumulating the error of the raw material plates and preventing the thickness error of the raw material plates from accumulating to an excessive level, resulting in the elastic vacuum suction head suddenly not coming into contact with the raw material plate and causing air suction or severely compressing the elastic vacuum suction head and deforming it.

[0019] 2. In the present invention, through the cooperation of the pressure sensor, the contact sensor, and the vertical lifting device, the thickness of the N-th raw material plate is calculated, and then the rising height of all the raw material plates in the stacking vehicle pushed by the vertical lifting device is changed. 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 vehicle are taken away in the present invention, the contact sensor will contact the top of the stacking vehicle and transmit a signal, while the pressure sensor has no object in contact with it, so it can automatically determine that the raw material plates in this stacking vehicle have been taken out completely, and there will be no situation where the elastic vacuum suction head sucks the bottom of the inner cavity of the stacking vehicle, nor is it necessary to use other equipment to determine whether the raw material plates in the stacking vehicle have been taken out completely.

[0031] In order to enable those skilled in the art to 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 described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0032] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0033] The present invention provides as Figure 1-7A stacking and feeding mechanism for a new energy electric vehicle battery cover is shown. In the prior art, there is a feeding frame 1, an XZ-axis transplanting component 2 installed on the feeding frame 1, a pneumatic material taking device 3 installed at the end of the output shaft of the XZ-axis transplanting component 2, a centering frame body 4 arranged in the middle below the feeding frame 1, a centering device 5 installed on the centering frame body 4, and a stacking vehicle 6 with raw material plates 7 of battery covers stacked inside. There are two stacking vehicles 6, which are respectively located at the bottoms on both sides of the feeding frame 1. When the stacking vehicle 6 is feeding on both sides of the centering frame body 4, it is in a predetermined position and cannot move. And we install a fence component 10 outside these devices for personnel protection. The pneumatic material taking device 3 itself includes a mounting frame 3a and a plurality of elastic vacuum suction heads 3b installed on the mounting frame 3a. When the elastic vacuum suction heads 3b contact the top surface of the raw material plate 7, the vacuum pump is controlled to make the elastic vacuum suction heads 3b generate suction force, and then the raw material plate 7 can be moved. Through the cooperation of the XZ-axis transplanting component 2, the raw material plate 7 can be moved into the centering device 5, and after centering, feeding is carried out;

[0034] Since the raw material plate 7 is allowed to have a thickness error during the production process. For example, for a plate with a thickness of 1 cm itself, raw material plates 7 with a thickness allowed to be between 0.9 cm and 1.1 cm are used for subsequent production. And a relatively large number of raw material plates 7 are stacked in the stacking vehicle 6. With the accumulation of each allowable error, the number of plates in one vehicle will be several more or several less. And if the XZ-axis transplanting component 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, there will suddenly be a situation where the elastic vacuum suction heads 3b do not fit the raw material plate 7, resulting in the failure to suck the raw material plate 7 onto the centering device 5, causing a chain reaction;

[0035] Therefore, a pressure component 3c that can slide vertically and detect the pressure value is fixedly installed on the mounting frame 3a. The pressure component 3c includes a hollow tube 3c1 fixed on the mounting frame 3a, a sliding rod 3c2 vertically and slidably installed in the hollow tube 3c1, a pressure sensor 3c3 fixedly installed at the bottom end of the sliding rod 3c2, and a spring 3c4 fixedly installed between the hollow tube 3c1 and the sliding rod 3c2. At the same time, a connecting piece 3d is fixedly installed on the mounting frame 3a, and a contact sensor 3e is fixedly installed at the end of the connecting piece 3d, and the contact sensor 3e is located directly above the side wall of the stacking vehicle 6, so that when the contact sensor 3e descends, it can contact the top of the stacking vehicle 6, thereby controlling the XZ-axis transplanting component 2 to stop descending. At the same time, a through hole 8 is opened in the middle of the stacking vehicle 6, and a vertical lifting device 9 composed of an electric telescopic rod 9a and a top plate 9b is installed on the fence component 10. When the output shaft of the electric telescopic rod 9a extends, the raw material plate 7 is pushed up through the top plate 9b;

[0036] When using this device, first stack the raw material plates 7 directly into the stacking vehicle 6 until the top surface of the topmost raw material is higher than the top surface of the stacking vehicle 6, but the top surface of the second-highest raw material plate 7 is lower than the top surface of the stacking vehicle 6. At the same time, it is best for us to replace the topmost 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 - 1.05 cm thick. At the beginning, the XZ-axis transplanting assembly 2 drives the pneumatic material-taking device 3 to descend. The pressure assembly 3c and the elastic vacuum suction head 3b will first contact the topmost raw material plate 7, and then the contact sensor 3e contacts the top surface of the stacking vehicle 6. At this time, the contact sensor 3e transmits a signal to the processor, and the processor controls the XZ-axis transplanting assembly 2 to stop descending. At this time, the pressure sensor 3c3 will push the sliding rod 3c2 to compress the spring 3c4, and the pressure sensor 3c3 will display the pressure generated when contacting the raw material plate 7. Record this pressure value A. Because the descending height of the contact sensor is fixed, the greater the pressure value detected by the pressure sensor 3c3, the higher the top surface of the raw material plate 7 in contact with the pressure sensor 3c3 is above the top surface of the stacking vehicle 6. Therefore, the distance between the top surface of the raw material plate 7 in contact with the pressure sensor 3c3 and the top surface of the stacking vehicle 6 can be calculated by the pressure value. For example, it is judged that the distance between the top surface of the first raw material plate 7 and the top surface of the stacking vehicle 6 is 0.45 cm. Then, in the manner of the existing technology, the elastic vacuum suction head 3b generates suction to move the raw material plate 7 to the centering device 5 in cooperation with the XZ-axis transplanting assembly 2. Here, in order to protect the contact sensor, a rubber material component is provided on the top of the stacking vehicle 6;

[0037] Then the electric telescopic rod 9a passes through the through hole 8 through the top plate 9b to lift the raw material plate 7 in the stacking vehicle 6 by 1 cm. After that, the XZ-axis transplanting assembly 2 drives the pneumatic material-taking device 3 to descend onto the stacking vehicle 6, as Figure 7As shown, after the second raw material plate 7 comes into contact with the pressure sensor 3c3, it will record the pressure value B. Using the pressure value, it can be determined that the distance between the top surface of the second raw material plate 7 and the top surface of the stacking truck 6 is, for example, 0.40 cm. 0.40 cm is 0.05 cm smaller than 0.45 cm. Assuming the thickness of the first raw material plate 7 is X, then 1 - (X - 0.45) = 0.4, and X = 1.05. After the second raw material plate 7 with an unknown thickness Y is taken away, the vertical lifting device 9 then lifts the raw material plate 7 in the stacking truck 6 by a height of 1.05 cm to eliminate the error of the first raw material plate 7. After the top surface of the third raw material plate 7 comes into contact with the pressure sensor 3c3, it will record the pressure value C. Assuming it is inferred that it is 0.35 cm higher than the top surface of the stacking truck 6, 1.05 - (Y - 0.4) = 0.35, and Y = 1.1 cm. Therefore, the vertical lifting device 9 then lifts the fourth raw material plate 7 in the stacking truck 6 by a height of 1.1 cm to eliminate the error of the second raw material plate 7. After the third raw material plate 7 with an unknown thickness Z is taken away, when the fourth raw material plate 7 comes into contact with 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 truck 6. Then 1.1 - (Z - 0.35) = 0.5, and Z = 0.95 cm. Then the vertical lifting device 9 then lifts the fifth raw material plate 7 in the stacking truck 6 by a height of 0.95 cm, and so on. The thickness error caused by the Nth raw material plate 7 will be manifested in the pressure value generated when the (N + 1)th raw material plate 7 comes into contact with the pressure sensor 3c3. From this, the thickness of the Nth raw material plate 7 is calculated, so that the vertical lifting device 9 lifts the (N + 3)th raw material plate 7 by a height equal to the thickness of the Nth raw material plate 7, so as to eliminate the thickness error caused by the Nth raw material plate 7, thereby re - accumulating the errors of the raw material plates 7, preventing the thickness errors of the raw material plates 7 from accumulating too large, and ensuring that each raw material plate 7 can normally come into contact with the elastic vacuum suction head 3b, and preventing the occurrence of situations such as empty suction and severe extrusion;

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

[0039] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should readily understand that many modifications are possible without materially departing from the novel teachings and advantages of the subject matter described in this application (e.g., variations in the dimensions, scales, structures, shapes, and proportions of various elements, as well as parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, colors, orientations, etc.).
