Description
Technical field
The utility model relates to a kind of double-sided automatic spot welding machine control device, is used in single-unit battery core and connects in the process of battery pack by nickel sheet, nickel sheet is welded on the connection in series-parallel that battery core surface realizes battery, and then composition battery pack, belongs to automatic control technology field.
Background technology
The structure of double-sided automatic spot welding machine as shown in Figure 1, comprise left screw mandrel 2 and right screw mandrel 9, left servomotor 1, right servomotor 8 are connected with left and right screw mandrel respectively, left spot welding head 3 and right spot welding head 7 are connected on left and right screw mandrel, left and right spot welding head is equipped with respectively left electrode bar 4 and right electrode bar 6, installs the tool 5 of battery core 10 between left and right electrode bar.
Connect in the process of battery pack in single-unit battery core by nickel sheet, need nickel sheet to be welded on battery core surface, the flow process of traditional double-sided automatic spot welding machine spot welding is: put into tool, and arrive specified point, point of arrival welding position, spot welding, completes.In above-mentioned flow process, because the reason such as machining, installation can make mash welder the right and left electrode bar different to the distance on battery core surface, when this can cause both sides electrode bar different, compress battery core.The making of tool is not the firm battery core of card, battery core can be caused to move, and be placed on the nickel sheet on battery core surface, can misplace thereupon yet, and then affect the quality of spot welding so compress battery core when both sides electrode bar is different.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of battery core that can prevent and moves the double-sided automatic spot welding machine control device with nickel sheet dislocation, to improve the quality of spot welding.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of double-sided automatic spot welding machine control device, double-sided automatic spot welding machine comprises left screw mandrel, right screw mandrel and the tool for assembling battery core, left servomotor, right servomotor respectively with left screw mandrel, right screw mandrel connects, left spot welding head, right spot welding head is connected to left screw mandrel, on right screw mandrel, left spot welding head, right spot welding head is respectively equipped with left electrode bar, right electrode bar, it is characterized in that: comprise PLC, level converter is connected with PLC, described left spot welding head, right spot welding head all connects level converter, PLC also with left servomotor, right servomotor connects, described battery core surface is provided with contact position.
Preferably, described left spot welding head, right spot welding head all connect described level converter by holding wire.
The device that the utility model provides is under automatic service condition before point of arrival welding position, fed back by electric circuit inspection and first arrive contact position, detect that both sides spot welding head all arrives contact position, now both sides extremely rod all contact battery core, at this condition point of arrival welding position again, such battery core would not produce movement, and nickel sheet also can not produce and misplace.
The device that the utility model provides overcomes the deficiencies in the prior art, prevents the movement of battery core and the dislocation of nickel sheet, improves point quality; Owing to contacting the appearance of position, the motion before contact battery core can arrange servomotor full speed running, thus also improves spot welding efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of double-sided automatic spot welding machine;
The double-sided automatic spot welding machine control device schematic diagram that Fig. 2 provides for the utility model;
The control method schematic diagram of the double-sided automatic spot welding machine control device that Fig. 3 provides for the utility model.
Detailed description of the invention
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The movement of battery core, the dislocation of nickel sheet are because both sides electrode is held in both hands surperficial different from the distance on battery core surface.When motor speed is identical, the time arriving battery core surface is different and produce.Controlling motor speed, to make electrode bar arrive time of motor identical, is need trial many times and inaccuracy.The control mode of stitch welding machine is position control mode, has a welding position, standby position etc., and therefore arrange the position on a contact battery core surface, before point of arrival welding position, two electrode bars just can realize arriving battery core surface simultaneously.Treat that both sides electrode bar all contacts with battery core, then carry out compression battery core, battery core would not produce movement, and nickel sheet also can not produce and misplace.
The double-sided automatic spot welding machine control device schematic diagram that Fig. 2 provides for the utility model, described double-sided automatic spot welding machine control device comprises holding wire 11, level converter 12, PLC13 etc., and arranges contact position on battery core surface.By left spot welding head 3, right spot welding head 7 connection signal line 11, and the signal carried by holding wire 11 is connected with PLC13 through level converter 12, and PLC13 exports the signal controlling servomotor, realizes the feedback of signal in automatic spot process.
Composition graphs 3, its control method is: rotated by left servomotor 1, right servomotor 8, drive left screw mandrel 2, right screw mandrel 9 rotates, make to be connected to the left spot welding head 3 on left screw mandrel 2, right screw mandrel 9, straight-line displacement occurs right spot welding head 7, when left spot welding head 3, right spot welding head 7 touch battery core surface namely to contact time, left electrode bar 4 on left spot welding head 3, right spot welding head 7, right electrode bar 6 are respectively by battery core surface conducting, Continuity signal transfers to PLC13 process by level converter 12, and PLC13 controls servomotor by processing signals and rotates or stop.
In automatic spot process, PLC13 can receive level variable signal, and whether arrives battery core surface according to signal judging point soldering tip and namely contact position, controls left and right servomotor forward-reverse, forms FEEDBACK CONTROL.When left spot welding head 3 or right spot welding head 7 arrive contact position, wait for that the right spot welding head of another side 7 or left spot welding head 3 arrive contact position on one side, after treating that the left and right spot welding head in both sides all arrives contact position, then move to a welding position with identical work speed, carry out spot welding.
The spot welding flow process of new stitch welding machine becomes: put into tool 5, and tool 5 reaches assigned address, and left and right spot welding head all arrives contact position, and left and right spot welding head is point of arrival welding position all, and spot welding is exited, and completes.
