The effect of upper push cylinder is to coordinate compression height finder structure linear slide rail 801 to realize moving up and down for pressing plate.
In order to allow those skilled in the art to more fully understand and realize the technical solution of the utility model, this is explained in detail below
The operation principle of embodiment.
Chucking position determines principle：
Feeding station and compression are surveyed between high station on workbench 1, and around the edge of rotating disk 702 6 photoelectric sensors are provided with,
Angle is 5 degree between each sensor；With immediately below any one machinery positioning fixture 2 as starting point on rotating disk 702, the lower section of rotating disk 702
Edge is equipped with a sensor chip around the center of circle of rotating disk 702 every 65 degree.Rotating disk 702 often rotates a station can be by control
The sensor sequence number that system processed is received analogizes chucking position differentiating grippers.
The operation principle of dispenser 708 in rotary disc assembly：
When adjusting 708 setting height(from bottom) of dispenser, the screw for somewhat unclamping wedge and lower wedge on height adjusting blocks leads to
The adjusting screw for crossing down wedge sidepiece is moved left and right, and the setting height(from bottom) of dispenser 708 also can be adjusted therewith, and lower wedge is adjusted to
Suitable height tightens again screw.
The rotation work process of rotating disk 702, when needing rotating disk 702 to rotate, system can be logical to controlled motor power supply by PLC
Disconnected one signal of telecommunication of relay, relay obtains electric rear motor energization and rotates, and machine shaft is driven moment of torsion by Timing Belt 703
It is driven to dispenser 708, dispenser 708 will be driven after 90 degree of break-in by internal structure, the rotating shaft of dispenser 708 band rotating disk 702
Rotate.
The dynamic work flow of cell sealing laser welding apparatus is as follows：
The first step, the feeding of conveying robot mechanism 3
After equipment starts, motor is rotated and drives dispenser operating.Conveying robot goes to automatic feed bin or leads to more during feeding
Road parallel conveying mechanism top, the band of four axis robot 302 pawl 502 of taking offence rotates to specified angle, unclamps Pneumatic clamping jaw 305, and four
Axis robot 302 is moved on on preprocessing battery 306, and gas pawl 502 clamps gripping preprocessing battery 306, in four axis robots 302
Rise, and be turned back to feeding station top, four axis robots 302 decline, and unclamp Pneumatic clamping jaw 305, and preprocessing battery 306 falls into machine
In tool positioning fixture 2, Pneumatic clamping jaw 305 rises awaits orders, and now feeding is completed.
Second step, compression height finder structure 4 work
After the completion of feeding, gas pawl 502 rises awaits orders and can give system one signal, illustrates that feeding is completed, and system receives letter
Number, after the completion for the treatment of other each station work, rotating disk 702 goes to next station.The initial cylinder push-rod of push cylinder 506 is pushed away on this station
To top, to three two three-way electromagnetic valves, one signal of connection 506 liang of QI KOU of upper push cylinder, air inlet/outlet transformation above pushes away gas to system
Cylinder 506 pulls down to bottom, and battery plate 804 is pushed, and the top cover surface of battery 306 is overwhelmed into fixed position, the machinery during pushing
Positioning fixture 2 can leave to battery 306 and push surplus because playing the role of extension spring and stage clip, but while battery 306 will not be allowed to fall
Go down.Pressing plate is depressed into behind fixed position, and the long minor face pressing plate of machinery positioning fixture 2 compresses the side of battery 306 allows it to fix.Pass
Distance measurement sensor 805 is released specified location and starts first point of height of measurement by sensor release cylinder 808, after being measured
Ball screw assembly, 809 drives sensor to move fixed range to next measurement point, so repeats survey and completes measurement, system for four times
Measurement data is judged, judges whether the pre- face of weld of top cover reaches solder side requirement for height, be, carry out subsequent work stations, otherwise
Workpiece is compressed positioning again, is repeated 2 times undesirable, is considered as defective work, directly skips other operations to blankers
Position is captured to substandard product area by conveying robot.After survey height is qualified, measurement sensor returns to the first measurement point, and by gas
Cylinder drives and pushes back, and subsequent upper push cylinder 506 promotes pressing plate to rise, and so far compresses the high operation of survey and completes.
3rd step, protective cover placement mechanism 5 work
After the completion of surveying high operation, rotating disk 702 goes to next station protective cover 402 and places.Original state gas pawl 502 is in L-type
Fixed support plate is reached after station near short brink, battery 306, and upper push cylinder 506 will support fixed plate 501 drop-down, gas pawl 502
Move down therewith, gas pawl 502 is in releasing orientation, cylinder pulls down to bottom seasonal epidemic pathogens pawl 502 and can just grip protective cover 402, subsequent gas
Pawl 502 clamps protective cover 402, and upper push cylinder 506 is above pushed away, and gas pawl 502 rises immediately, the pusher cylinder of mounting base to after top
505 extrapolate gas pawl 502, shift the top cover of battery 306 top onto, then go up the 502 times general who has surrendered's protective covers of drop-down gas pawl of push cylinder 506
402 are put on the top cover of battery 306 rear release gas pawl 502, and gas pawl 502 returns to initial position.It is complete operation to be placed to this protective cover 402
Into.
4th step, laser welding mechanism 6 work
After the completion of protective cover 402 is placed, rotating disk 702 goes to laser welding station, now laser focal and CCD camera 608
Focusing has manually been mixed up, without the need for moving again.CCD carries out shooting of taking pictures to product, by the photo for photographing and pre-set
Standard welding position picture be compared, be to refer to comparison point with top cover bottom left vertex, calculating difference, and by difference compensation arrive
In galvanometer welding, angle air knife 603 starts to blow top cover, blows out as the inertia shielding gas such as nitrogen, and gas is formed and carried
The wide opening air curtain of certain pattern draft can cover the top cover whole of battery 306.Noble gases blow to Jing behind top cover surface and reflex to and remove
Dust suction in dust hood suction range is discharged.Laser instrument 601 starts to carry out galvanometer laser welding to the top cover of battery 306, welds during welding
Light path is setting value, and welding every time can carry out carrying out light path again according to setting light path and vision localization difference to welding light path
Setting.When the welding of laser galvanometer is carried out, the angles of two rotation eyeglasses in galvanometer are changed by corresponding control system, so as to change
Becoming position that laser projects and direction can just change the location point of welding, at the same laser head adopt telecentric lens it is prevented that
The weld pads concordance for ensureing welding of different sizes that laser is caused because of exit positions direction difference.
5th step, protective cover feel trim actuator 7 work, the step of it is placed with protective cover 402 conversely, here just no longer one by one
Description.
6th step, the discharging of first step conveying robot mechanism 3, step phase consistent with conveying robot mechanism 3 feeding principle
Instead, here is just also no longer described one by one.
Although the foregoing describing specific embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely illustrative of, and can make various changes or modifications to present embodiment, without departing from original of the present utility model
Reason and essence, protection domain of the present utility model is only limited by the claims that follow.
