DETAILED DESCRIPTION
[0027] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the accompanying drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.
[0028] The following will refer to the accompanying drawings and describe in detail the technical solutions provided by the present invention through embodiments. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation on the present invention.
[0029] In some examples, since some embodiments belong to the prior art or conventional technology, they are not described or not described in detail.
[0030] In addition, the technical features described herein, or the steps in all the methods or processes disclosed, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy to understand that the steps or operation sequences of the methods related to the embodiments provided herein can also be changed. Any sequence in the drawings and embodiments is only for illustrative purposes and does not imply a requirement to follow a certain sequence, unless clearly stated to require a certain sequence.
[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in this application, under reasonable circumstances (without self-contradiction), both include direct and indirect connection (coupling).
[0032] The lithium battery integrated busbar generally includes a bracket and an aluminum bar, and both the bracket and the aluminum bar have positioning holes; and a part of the positioning holes of the aluminum bar and a part of the positioning holes of the bracket coincide. For large-size lithium battery integrated busbars, their brackets are usually spliced by multiple sub-units and have a long length. Therefore, it is very necessary to design a loading system that facilitates the transfer of large-size lithium battery integrated busbars between various assembly devices.
[0033] As Figure 1 、 2 and shown in 3, the loading system of the lithium battery integrated busbar in this embodiment includes a rectangular frame 1, a support 2 for supporting the bracket, and a positioning pin for positioning and cooperating with the positioning holes of the aluminum bar and / or the bracket; the rectangular frame 1 has four positioning holes distributed in a rectangle, and each positioning hole is fitted with a positioning sleeve 3; each side of the rectangular frame 1 includes a metal strip 4 and a plastic strip 5 provided below the metal strip 4; the density ρ of the metal strip 4 ≤ 2.75 g / cm3 ; The bottom surface of the metal strip 4 has a downwardly extending support section 6; A label 19 with a bar code or a two-dimensional code is provided on the top surface of one of the metal strips 4; The bottom surface of the support section 6 is not lower than the bottom surface of the plastic strip 5; The bottom surfaces and both sides of the metal strips 4 on the two long sides of the rectangular frame 1 have chutes 7 along their lengths, and the cross-section of the chute 7 is T-shaped or dovetail-shaped; The support 2 is connected to the rectangular frame 1, and at least the two ends of one of the supports 2 are respectively connected to the two long sides of the rectangular frame 1; The positioning pin is connected to the support 2.
[0034] The positioning sleeve 3 can be fixed to the positioning hole by means of glue bonding, interference fit, etc.; A stepped positioning sleeve 3 can also be selected, and the positioning hole is also in a stepped shape adapted to the positioning sleeve 3, so as to prevent the positioning sleeve 3 from falling off. By providing four positioning sleeves 3, a jacking and positioning mechanism can be provided at each device of the production line. The jacking and positioning mechanism re-positions the entire loading system through positioning cooperation with the four positioning sleeves 3, so that the loading system is accurately aligned with each device of the production line.
[0035] The positioning pin can be fixed to the support 2 by means of glue bonding, interference fit, etc.; It should be noted that since the bracket is located below the aluminum bar, the positioning pin can directly cooperate with the positioning hole of the bracket; Since the positioning pin has a certain length, it is best for the positioning pin to be positioned and cooperate with the positioning hole where the bracket and the aluminum bar overlap or the positioning hole without obstruction above the bracket; At the same time, the positioning pin can also cooperate with the positioning hole of the aluminum bar, and at this time the bracket below the aluminum bar is clear of space.
[0036] The rectangular frame 1 is the basis of the entire loading system and needs to have a certain strength and stiffness. And since the loading system needs to be transferred at each device of the production line, such as belt conveying, roller conveying, etc., the rectangular frame 1 also needs to have wear resistance. Therefore, the four metal strips 4 on the upper layer enclose a rectangle, so that the rectangular frame 1 meets the strength and stiffness requirements of the loading system. At the same time, the four plastic strips 5 on the bottom layer enclose a rectangle and are in contact with belt conveying, roller conveying, etc., so that the rectangular frame 1 is more wear-resistant.
[0037] The integrated busbar of the lithium battery is relatively large in size, so the size of the loading system is also relatively large. The weight of the entire loading system needs to be considered. Therefore, by adopting a combination method of metal strips 4 and plastic strips 5, while meeting the strength, stiffness and wear resistance, the weight of the entire loading system can also be reduced; Secondly, by using a density ρ≤2.75g / cm 3The metal strip 4 further reduces the weight of the entire load-bearing system. In this embodiment, the metal strip 4 is made of aluminum alloy profile, so that the metal strips 4 of multiple load-bearing systems can be prepared by a set of molds, with better consistency. At the same time, the aluminum alloy profile can be provided with multiple hollow parts, which not only reduces the weight but also improves the bending strength of the entire rectangular frame 1, with better flatness. In some other embodiments, the metal strips 4 on the long sides of the rectangular frame 1 are made of aluminum alloy profile, and the metal strips 4 on the short sides of the rectangular frame 1 are made of aluminum alloy plates. In this embodiment, the plastic strip 5 is made of nylon.
[0038] If the above-mentioned jacking and positioning mechanism directly contacts the plastic strip 5 when jacking the load-bearing system, it may cause damage to the surface of the plastic strip 5 and reduce its wear resistance. Therefore, contacting the jacking and positioning mechanism through the extended metal support section 6 can effectively avoid this problem. The support section 6 can be connected to the metal strip 4 by means of screws or the like. Open holes at the corresponding positions of the plastic strip 5 so that the support section 6 can be exposed.
[0039] By opening a sliding groove 7 on the metal strip 4, a preset nut can be placed in the sliding groove 7. Since the cross-section of the sliding groove 7 is T-shaped or dovetail-shaped, the preset nut will not fall off, thus facilitating the installation of accessories such as the support 2 and facilitating the adjustment of the positions of accessories such as the support 2.
[0040] By connecting the two ends of at least one of the supports 2 to the two long sides of the rectangular frame 1 respectively, the support 2 acts as a reinforcing rib of the rectangular frame 1 while supporting the support bracket, thereby improving the stiffness of the entire rectangular frame 1. The end of the support 2 close to the rectangular frame 1 is T-shaped or L-shaped, so that the support 2 can be connected to the rectangular frame 1 by screws and the preset nuts in the sliding groove 7.
[0041] The metal strips 4 can be connected by accessories such as a tripod or directly by screws or the like; the plastic strip 5 can be connected to the metal strip 4 by screws or the like.
[0042] Such as Figure 3 and 4As shown, the rectangular frame 1 is connected with four inverted L-shaped hooks 11, and the four inverted L-shaped hooks 11 are distributed in a rectangular shape or a rhombus shape. Thus, it is convenient to cooperate with the four inverted L-shaped hooks 11 through a manipulator to hoist the entire bearing system to each device on the production line. The four inverted L-shaped hooks 11 distributed in a rectangular shape or a rhombus shape can ensure that the center of gravity of the entire bearing system is located inside the quadrilateral with the four inverted L-shaped hooks 11 as vertices, greatly reducing the risk of the bearing system tipping over during hoisting. The four inverted L-shaped hooks 11 can be fixed to the rectangular frame 1 through screws and pre-set nuts in the sliding grooves 7. Further, the inverted L-shaped hook 11 has a positioning groove 12; the positioning groove 12 is trapezoidal. Thus, when hoisting the bearing system, by cooperating with the positioning groove 12, the device for hoisting the bearing system can position the bearing system, ensuring that the position of the bearing system is more accurate during hoisting and transfer; at the same time, by setting the trapezoidal positioning groove 12 and using the two inclined surfaces of the trapezoid, the device for hoisting the bearing system can be automatically aligned with the inverted L-shaped hook 11.
[0043] As Figure 3 and 4 As shown, at least two receiving blocks 13 that are all adapted to the sliding grooves 7 are provided on the opposite side surfaces of the metal strip-shaped objects 4 on the two long sides of the rectangular frame 1; at least a part of the outer side surface of the receiving block 13 is a stepped surface 14. By providing the receiving blocks 13, after the bearing system is lifted on the production line, by providing a supporting device inserted into the stepped surface 14 to support the bearing system, it is convenient for the next bearing system on the production line to pass through. Two threaded holes can be opened on the bearing block, and set screws are fitted in the two threaded holes, so that the receiving blocks 13 can be fixed to the sliding grooves 7.
[0044] As Figure 3 and 5 As shown, positioning blocks 15 are embedded on the opposite side surfaces of the metal strip-shaped objects 4 on the two short sides of the rectangular frame 1; the outer side surface of the positioning block 15 has a trapezoidal groove 16. Thus, each device on the production line can position the bearing system in the width direction of the rectangular frame 1 through the trapezoidal groove 16 of the positioning block 15.
[0045] In some embodiments, both ends of the metal strip-shaped objects 4 on the two short sides of the rectangular frame 1 at least seal a part of the plastic strip-shaped objects 5 on the two long sides of the rectangular frame 1 to prevent the plastic strip-shaped objects 5 on the two long sides of the rectangular frame 1 from moving along their length directions; for example, the metal strip-shaped objects 4 on the two short sides of the rectangular frame 1 are the ends of the rectangular frame 1, that is, the metal strip-shaped objects 4 on the two short sides of the rectangular frame 1 are located outside the ends of the metal strip-shaped objects 4 on the two long sides of the rectangular frame 1.
[0046] As Figure 2As shown in the figure, the top of the plastic strips 5 on the two long sides of the rectangular frame 1 has an adaptation part 17 adapted to the chute 7 of the corresponding metal strip 4; that is, the cross-section of the adaptation part 17 is also T-shaped or dovetail-shaped, and the adaptation part 17 is embedded in the bottom chute 7 of the metal strip 4; both ends of the metal strips 4 on the two short sides of the rectangular frame 1 cover at least a part of the adaptation part 17; as Figure 1 and 3 shown, the two ends of the metal strips 4 on the two short sides of the rectangular frame 1 protrude, covering all the ends of the plastic strips 5 on the two long sides of the rectangular frame 1, thus preventing them from falling off.
[0047] As Figure 6 shown, the bearing system may further include a plurality of acquisition devices and a first controller 8 electrically connected to the plurality of acquisition devices respectively; the acquisition device includes a code scanning device 9 for obtaining the information of the tag 19 and a second controller 10 electrically connected to the code scanning device 9; the information of the tag 19 at least includes the integrated busbar number information, the name of the processing procedure, the abnormal information, and the processing qualification information; the plurality of second controllers 10 are all electrically connected to the first controller 8 for uploading the information obtained by the code scanning device 9 to the first controller 8. During use, the code scanning device 9 and the second controller 10 are respectively installed on each device of the production line. When the bearing system reaches the corresponding device, the code scanning device 9 of the device is activated, reads the information of the tag 19 of the bearing system, and uploads the operation information of the device, such as the name of the processing procedure, together with the information such as the integrated busbar number information to the first controller 8. The first controller 8 saves this information into the server 18, such as the MES system, for easy calling; at the same time, the device can also obtain information from the first controller 8 through the second controller 10, and this information includes whether the lithium battery integrated busbar of the bearing system has the content of repeating the operation of this device.
[0048] The present utility model is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they all fall within the protection scope of the present utility model.
