[0028] The utility model is further described below in conjunction with embodiments.

[0029] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0030] Example 1

[0031] Please refer to the instruction manual Figure 1-5 , a combined grasping fixture of a battery box cover and a tray, comprising a frame 2, a robot flange 1 is fixedly mounted on the frame 2, and the frame 2 is connected to a six-axis robot through the robot flange 1;

[0032] The four corners of the frame 2 are provided with a clamping mechanism 3 and a latch mechanism 4, a plurality of suction cups 5 are fixedly installed at the bottom of the frame 2, a distance measuring system 6 and a product presence detection system 7 are fixedly installed on the right side of the frame 2, the product presence detection system 7 is located on the rear side of the distance measuring system 6, and an automatic code scanning system 8 is installed on the left side of the frame 2.

[0033] After the battery box cover and the pallet arrive at the specified position, the automatic scanning system 8 scans the pallet for confirmation, the product presence detection system 7 detects that the battery box cover is on the pallet, and then the distance measuring system 6 measures the distance of the pallet. When the distance measuring system 6 obtains the correct distance, the six-axis robot controls the frame 2 to move to the grasping position, and then the latch mechanism 4 locks the pallet, the clamping mechanism 3 clamps the battery box cover, and the suction cup 5 absorbs the battery box cover. The six-axis robot thereby grasps the combination of the battery box cover and the pallet, lifts it and moves it to the specified position. The utility model can grasp the battery box cover and the pallet at one time, reduces the time loss in the grasping process, and improves the production efficiency.

[0034] Example 2

[0035] like Figure 1-5 As shown, as a preferred embodiment of the utility model, taking one of the clamping mechanisms 3 as an example, the clamping mechanism 3 includes a clamping cylinder 9, a fixing seat 10, a gasket 11, a support block 12, a clamping block 13, a gasket 14, a clamping connector 15 and a pressure block 16. The fixing seat 10 is fixedly installed on one side of the frame 2, the clamping cylinder 9 is fixedly installed on one side of the fixing seat 10, the gasket 11 is fixedly installed between the fixing seat 10 and the support block 12 to adjust the distance between the two, the clamping connector 15 and the pressure block 16 are fixedly connected, and the connection between the clamping connector 15 and the pressure block 16 is fixedly connected to the output end of the clamping cylinder 9, and the gasket 2 14 is fixedly installed between the clamping block 13 and the clamping connector 15 to adjust the distance between the two.

[0036] The clamping cylinder 9 is a clamping lever cylinder.

[0037] Taking one of the latch mechanisms 4 as an example, the latch mechanism 4 includes a locking cylinder 17, a cylinder mounting plate 18, a connecting rod 19, a sensor 20, a bracket 21, a profile 22, a connecting plate 23, a second fixing seat 24, an adjusting block 25, an adjusting bolt 26 and a third gasket 27. The locking cylinder 17 is fixedly mounted on the cylinder mounting plate 18. Four connecting rods 19 are provided and are fixedly mounted between the cylinder mounting plate 18 and the connecting plate 23. The side walls of the cylinder mounting plate 18 and the connecting plate 23 are fixedly connected to the profile 22. Then, the bracket 21 is slidably connected to the side wall of the profile 22, the sensor 20 is fixedly installed on one side of the bracket 21, the bracket 21 can be adjusted on the profile 22, so as to adjust the position of the sensor 20, the connecting plate 23 is fixedly installed on the second fixing seat 24, the gasket three 27 is fixedly installed between the frame 2 and the second fixing seat 24, and is used to adjust the distance between the two, one side of the second fixing seat 24 is detachably connected to the adjusting block 25 by the adjusting bolt 26, and the adjusting bolt 26 adjusts the distance between the second fixing seat 24 and the adjusting block 25.

[0038] The locking cylinder 17 drives the latch 30 to position the pallet. The latch 30 is arranged in the cavity of the second fixing seat 24. When the transport box cover and the pallet are lifted, the locking cylinder 17 does not bear the radial force applied by the pallet. Most of its pressure is borne by the second fixing seat 24, which greatly reduces the pressure on the locking cylinder 17 and extends the service life of the cylinder.

[0039] The sensors 20 and brackets 21 are provided in two groups and are arranged on the profile 22 .

[0040] The latch mechanism 4 also includes a collar 28, a floating joint 29, a latch 30, a bushing 31 and an end cover 32. The bushing 31 is fixedly installed inside the fixing seat 24, and the end cover 32 is fixedly installed at the end of the fixing seat 24. The latch 30 is slidably connected to the inside of the bushing 31. The top end of the latch 30 is fixedly connected to the output end of the locking cylinder 17 through the floating joint 29, and the collar 28 is fixedly connected to the end of the latch 30.

[0041] The sensor 20 is used to detect the position of the collar 28 , thereby confirming the extended and retracted positions of the piston rod of the locking cylinder 17 .

[0042] When the distance measuring system 6 obtains the correct distance, the frame 2 moves to the grasping position, at which time the piston rod of the locking cylinder 17 extends, thereby driving the latch 30 to extend. After the latch 30 reaches the specified position and matches with the pin hole on the pallet, the locking device of the locking cylinder 17 locks the piston rod to prevent the latch 30 from moving during transportation. At the same time, after the sensor 20 receives the signal, the output end of the clamping cylinder 9 drives the clamping block 13 to rotate to press the edge of the battery box cover against the support block 12, thereby clamping the battery box cover. At the same time, the suction cup 5 passes through the pallet to absorb the battery box cover and fix the battery box cover on the pallet to absorb the battery box cover and prevent it from deformation. The clamping cylinder 9 will feedback the clamping signal, and then the six-axis robot grabs the combination of the battery box cover and the pallet, lifts it and moves it to the specified position.

The shield 40 is fixedly installed on the connecting block 39, and the code scanning device 41 is fixedly installed inside the shield 40. The shield 40 is used to scan the QR code on the pallet to confirm the pallet information.

[0046] The shield 40 is adjusted to a suitable position by adjusting the positions of the connecting block 1 35, the connecting block 2 37, and the connecting block 3 39 on the adjusting rod 1 34, the adjusting rod 2 36, and the adjusting rod 3 38, and then the connecting block 1 35, the connecting block 2 37, and the connecting block 3 39 are locked in sequence by bolts, and then the scanning device 41 scans the pallet to confirm the information.
