[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A milling device for a battery compartment weld, the device comprises a workbench, a workpiece conveying mechanism arranged on the workbench, a milling machine arranged on both sides of the workbench and adapted to the workbench, a protective cover arranged outside the milling machine, and a debris collection mechanism, wherein the workbench is provided with a feed detection station, a milling station, and a discharge detection station in sequence along its length direction, the milling machine is adapted to the milling station, and the feed detection station and the discharge detection station are both provided with a workpiece weld detection mechanism. The workpiece conveying mechanism is used to transport the battery compartment workpiece between the feed detection station, the milling station, and the discharge detection station. The milling machine is used to mill the battery compartment workpiece entering the milling station to remove burrs and excess parts at the weld on the battery compartment. The weld detection mechanisms on the feed detection station and the discharge detection station are respectively used to detect the battery compartment weld before and after milling.

[0007] The device also includes controllers that are respectively adapted to the workpiece conveying mechanism, the milling machine, the debris collection mechanism, and the workpiece weld detection mechanism. The controller is used to regulate the coordinated work of each mechanism. The entire device is located in a noise reduction room to further reduce noise.

[0008] Furthermore, the workpiece conveying mechanism is arranged on the workbench along the length direction of the workbench, and the workpiece conveying mechanism drives the battery compartment to move from the feeding detection station to the milling station and the discharging detection station in sequence.

[0009] Furthermore, the workpiece conveying mechanism includes a servo slide arranged on the workbench along the length direction of the workbench, a connecting plate movably arranged on the servo slide, and a workpiece fixture arranged on the connecting plate, and the battery compartment is arranged on the workpiece fixture. The robot places the battery compartment workpiece on the workpiece fixture, and the workpiece fixture is clamped and fixed; then the servo slide drives the workpiece fixture to move through the connecting plate.

[0010] Furthermore, the workpiece weld detection mechanism includes a pair of sensor brackets arranged on the workbench and respectively located on both sides of the workpiece conveying mechanism, and a pair of laser distance measuring sensors are arranged on the sensor bracket, and the two laser distance measuring sensors are respectively arranged on the sensor bracket, one above and one below. The laser distance measuring sensor on the upper part of the sensor bracket is used to detect the weld on the upper surface of the battery compartment, and the surface quality of the weld is judged according to the distance between the top of the weld and the laser distance measuring sensor measured by the laser distance measuring sensor; the laser distance measuring sensor on the lower part of the sensor bracket is used to detect the weld on the lower surface of the battery compartment. The sensor brackets on both sides of the workpiece conveying mechanism respectively detect the upper and lower surface welds on both sides of the battery compartment. The workpiece weld detection mechanism of the feeding detection station is used to detect the quality of the weld on the battery compartment before milling; the workpiece weld detection mechanism of the discharging detection station is used to detect the quality of the weld on the battery compartment after milling.

[0011] Furthermore, the sensor bracket is C-shaped, and laser ranging sensors are provided on the top lower surface and the bottom upper surface of the sensor bracket.

[0012] Furthermore, the milling machine is provided with a pair of milling assemblies, the two milling assemblies are respectively located on both sides of the workpiece conveying mechanism, and the milling assembly includes a three-coordinate moving table, a tool holder arranged on the three-coordinate moving table, and a milling cutter arranged on the tool holder.

The two milling assemblies can work independently and have a large range of milling working areas, and can directly mill all the welds on the battery compartment without the need to use other equipment for secondary processing in the subsequent process.

[0013] Furthermore, the chip collection mechanism includes a chip flute arranged below the protective cover and connected to the inside of the protective cover, a chip discharge channel connected to the chip flute, and a chip receiving box connected to the chip discharge channel. The chips produced by milling fall down into the chip flute and enter the chip receiving box through the chip discharge channel, thereby preventing the waste chips from entering the external air.

[0014] Furthermore, a spiral chip conveyor is provided in the chip conveying channel, and the spiral chip conveyor conveys the debris in the chip conveying channel to a chip receiving box.

[0015] Furthermore, a slot is formed at the bottom of the protective cover, and the slot is connected to the chip flushing groove. The chips produced by milling are intercepted by the protective cover and fall downward, and enter the chip flushing groove through the slot.

[0016] Furthermore, a dust hood adapted to the milling machine is provided in the protective cover, and the dust hood is connected to the chip removal channel. The dust hood is connected to the chip removal channel through a pipeline, and during the milling process, the fine aluminum chips on the surface of the workpiece are sucked away by the dust hood and sent to the chip removal channel.

[0019] When the present invention is actually applied, the robot places the battery compartment after aluminum welding on the workpiece fixture, and positions and fixes it through the positioning pins, clamps, etc. on the workpiece fixture; then the servo slide transports the battery compartment between the feeding inspection station, the milling station, and the discharging inspection station in sequence.

[0020] Among them, when the battery compartment is located at the feeding detection station, the laser ranging sensor detects the welds on the upper and lower surfaces of the battery compartment and feeds back to the controller to adjust the feed amount of the milling cutter in the milling machine.

[0021] When the battery compartment is located at the milling station, the milling cutter will mill and deburr the weld. Due to the protection of the protective cover, aluminum chips can be prevented from flying out of the milling station. The aluminum chips in the protective cover fall into the chip trough through the slot holes at the bottom, and the dust hood collects the fine aluminum chips on the surface of the workpiece. All the aluminum chips enter the chip discharge channel and are sent to the chip receiving box via the spiral chip conveyor.

[0022] After the milling process is completed, the battery compartment enters the discharge inspection station, where the laser distance sensor detects the welds on the upper and lower surfaces of the battery compartment and feeds the results back to the controller to determine the milling effect. If the surface quality of the workpiece is unqualified, the servo slide moves in the opposite direction to return the workpiece for repair; if the surface quality of the workpiece is qualified, it continues to move to the exit and is finally removed by the robot.

[0023] Compared with the prior art, the present invention has the following characteristics:

[0024] 1) The present invention adopts an automated method to realize automatic positioning, conveying, milling and detection of the battery compartment, thereby improving positioning accuracy and work efficiency, better controlling the milling quality, and reducing safety hazards of operators.
