Example 1
Referring to fig. 1 and 2, an embodiment of the present application provides an automatic tightening system including a first tightening device 10 and a second tightening device 20;
the first tightening device 10 and the second tightening device 20 are arranged on the left side and the right side of the conveying member 30 of the production line, respectively;
the first tightening device 10 is used for tightening at a left tightening point 60 (shown in fig. 3) of the to-be-tightened piece, the second tightening device 20 is used for tightening at a right tightening point 60 of the to-be-tightened piece, and the first tightening device 10 and the second tightening device 20 are not linked.
Because the first tightening device 10 and the second tightening device 20 are not linked, the tightening points 60 can be respectively tightened, the tightening points 60 on the left side and the right side of the battery can be freely tightened, mutual interference is avoided, and a tightening shaft is not required to be arranged at each point, so that the efficiency is guaranteed, and the economy is improved.
Referring to fig. 3, fig. 3 shows the tightening device on one side thereof. The first tightening device 10 and the second tightening device 20 of the present embodiment each include: an X-direction servo walking device 51, a Y-direction servo walking device 52, a Z-direction servo walking device 53 and a tightening member 54.
The movement direction of the X-direction servo traveling device 51 is parallel to the movement direction of the conveying member 30, the Y-direction servo traveling device 52 is arranged on the X-direction servo traveling device 51 and can move along with the X-direction servo traveling device 51, the Z-direction servo traveling device 53 is arranged at the output end of the Y-direction servo traveling device 52, and the tightening member 54 is arranged at the output end of the Z-direction servo traveling device 53.
Regarding the X-direction servo traveling device 51, specifically, the X-direction servo traveling device 51 includes a sliding seat 501, a servo motor 502 and a rack 503, the servo motor 502 is disposed on the sliding seat 501, the sliding seat 501 is disposed on the rack 503, an output end of the servo motor 502 is engaged with the rack 503, and the Y-direction servo traveling device 52 is connected to the sliding seat 501. The servo motor 502 is matched with the rack 503, so that the adjustment is accurate, the back and forth driving can be realized, and the screwing operation is convenient.
The X-direction servo traveling device 51, the Y-direction servo traveling device 52, and the Z-direction servo traveling device 53 are engaged with each other, so that the tightening members 54 on the left and right sides can be moved to the tightening points 60 on the two sides, respectively, to complete the tightening.
In detail, the tightening member 54 includes a mount 504, a first tightening shaft 505 and a second tightening shaft 506, the mount 504 is connected to an output end of the Z-directional servo traveling device 53, and the first tightening shaft 505 and the second tightening shaft 506 are provided side by side to the mount 504.
The two tightening shafts can work together or independently so as to tighten bolts at fixed points or special points. The distance between the first tightening shaft 505 and the second tightening shaft 506 is a preset distance, and the first tightening shaft 505 and the second tightening shaft 506 are not linked. The preset pitch of this embodiment is 284 mm.
The preset interval is an interval determined by combining with the early design of the new energy battery, and the designed fixed interval can form a cooperation with the product battery and a production line together to improve production by comprehensively considering the aspects of screwing implementation, process mode maintenance and the like in the early stage of the design stage. For the combination of the power batteries, the space for automatic screwing is limited, if a variable-pitch double shaft is adopted, the space of the power battery combination line 40 and the screwing device is occupied, and the collinear production of multiple vehicle types cannot be realized.
It is to be understood that the preset spacing may be the spacing between two adjacent tightening points 60; it is also possible to stagger the distance between the two tightening points 60, i.e. there may be other tightening positions between the tightening points 60, without affecting the tightening of the two points that are spaced 284mm apart.
In addition, for a special point where the distance is not 284mm, it is obviously not suitable for two tightening shafts to work simultaneously, therefore, the first tightening shaft 505 and the second tightening shaft 506 of the present embodiment can work independently, and when one of them is not needed, the first tightening shaft 505 and the second tightening shaft 506 can be shielded from rotating, so as to avoid affecting the safety of the battery or other objects needing to be tightened.
It is to be understood that the first tightening shaft 505 and the second tightening shaft 506 in this embodiment are floatingly coupled to the mounting member 504 by a bearing floating assembly. The bearing floating assembly can absorb accumulated errors and ensure the reliability of each screwing operation. The components and manner of the floating connection can be referred to in the prior art and will not be described in detail here.
Referring to fig. 1 and fig. 2 again, based on the automatic tightening system, an embodiment of the present application provides a power battery production line, which includes a power battery assembly line 40 and an automatic tightening system, wherein a first tightening device 10 and a second tightening device 20 of the automatic tightening system are respectively disposed on left and right sides of a sled device for carrying a tray and a battery of the power battery assembly line 40. Wherein the power battery assembly line 40 only shows a partial structure, the conveying member 30 can be placed on the power battery assembly line 40 to transfer the battery or other objects to be tightened between two tightening devices. Through adopting this automatic system of screwing up, the efficiency of power battery production line can be higher, and has reduced the cost of labor, has reduced the cost of screwing up equipment, and is more beneficial to enterprise's production.
The principle of the embodiment is as follows:
taking the example of the tightening of the battery, the tightening of the power battery is generally performed manually to improve the economy, and for the automatic tightening technology, the tightening mechanisms on the left and right sides generally need to share the X-axis rail at present, and the tightening mechanism on one side alone cannot adjust the X coordinate alone without affecting the other side. When the product changes, in the later production process, it is difficult to realize differentiated production, and the precision of screwing up also can meet the bottleneck because of the change of product.
In view of the above, in order to improve efficiency and compatibility, the present embodiment provides an automatic tightening system, and applies the automatic tightening system to the power battery assembly line 40 as a part of the power battery production line to improve production efficiency.
Specifically, in the design stage of the power battery, the characteristics that the power battery is flat and aluminum frames on two sides are main stress points are combined, adjacent and staggered screwing point positions 60 are designed, and the distance is fixed to be 284 mm. Practice proves that the performance requirements of the product are met, and the spatial arrangement of equipment is facilitated.
The first tightening device 10 and the second tightening device 20 integrate walking and tightening, for the left and right sides of the power battery, each point in the X-axis direction can be tightened by the tightening device, and it is not necessary for the two tightening devices to move simultaneously in the X-axis direction, and in the prior art, the movement in the X-axis direction can only be one-way, and in this embodiment, the sliding seat 501 can move back and forth in the X-axis direction by the cooperation of the servo motor 502 and the rack 503, so as to work at different points.
When a power battery of a certain model needs to be produced, the tightening point 60 corresponding to the model may be designed in advance, and the point information may be stored in an upper computer of the automatic tightening system, such as a controller of a power battery production line. Then, the work number can be programmed on the operation interface of the controller, and the first tightening device 10 and the second tightening device 20 can independently adjust the coordinates of their X, Y, Z axes according to the programmed work order, so that the respective tightening members 54 work, and can tighten using the first tightening shaft 505 or the second tightening shaft 506 alone for the tightening points 60 that are not at a fixed distance. When the vehicle type changes, only the working sequence needs to be compiled according to the new point location. Through practice, the current automatic tightening system can be compatible with automatic tightening operations of 5 power batteries, the coverage rate of tightening points 60 of different power batteries reaches 100%, and the success rate of tightening reaches 99.7%.
By combining actual measurement and calculation, compared with the traditional manual tightening mode, the automatic tightening system saves manual pre-tightening workers in the assembling process and tightening workers after assembling, and saves 4 workers in two shifts; compared with a full-shaft tightening high-input process form in which a tightening shaft is arranged at each point, the method saves about 300 to 400 ten thousand of equipment investment, and is extremely favorable for improving the production efficiency and saving the production cost.
It is understood that the embodiment is exemplified by the tightening of the power battery, and when the object to be tightened is other, it is also considered to adopt the solution of the present application, for example, in the front suspension and rear suspension automatic tightening, the automatic tightening system can also be adopted.
To sum up, the automatic screwing system of this application, through the cooperation of first screwing up device 10 and second screwing up device 20, can treat respectively to screw up the left side of object and the right side and screw up position 60, and the work mutual noninterference of the two just can adjust respectively, can effectively improve and screw up efficiency, can also realize in addition that the order is screwed up or the combination of processes such as diagonal angle screw up, the flexibility is good. The tightening device can be compatible with tightening work of different batteries and different tightening processes, the whole scheme is good in implementation flexibility and low in cost, and the existing problems are solved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
