In view of this, a new solution is needed to improve the adaptability between the robot and the tool.

Referring to fig. 1-6 b, according to one embodiment of the present application, a switching device is provided. The switching device 1 comprises a switching bracket 11, a first switching disc 12 and a second switching disc 13, wherein the switching bracket 11 is provided with a first switching surface 101 and a second switching surface 102;

the first switching disc 12 is mounted to the first transition surface 101; the second switching disc 13 is mounted on the second switching surface 102;

the first switch disc 12 is configured for mating connection with a third switch disc of the robot, and the second switch disc 13 is configured for mating connection with a fourth switch disc of the tool;

wherein the third switching disc of the robot has the same structure as said second switching disc 13 and the fourth switching disc of the tool has the same structure as said first switching disc 12.

Taking a welding operation by holding a welding tongs by a robot as an example, the robot 2 is connected with a tool 3 for the welding operation, and the tool 3 is the welding tongs.

Referring to fig. 2a, without using the adapter device 1 provided in the embodiment of the present application, the robot 2 is directly connected to the tool 3, specifically, the third switching plate 21 of the robot 2 is connected to the fourth switching plate 31 of the tool 3; in the case where the robot 2 is directly connected to the tool 3, the robot 2 can be connected to the tool 3 only from the rear of the tool 3. In some conditions, the robot 2 is connected to the tool 3 from the rear of the tool 3, so that the welding is not available, and the welding operation cannot be performed normally.

In the case of the adapter device 1 provided in the embodiment of the present application, the first switching disc 12 installed on the first adapting surface 101 of the adapter device 1 is used for connecting the third switching disc 21 of the robot 2, and the second switching disc 13 installed on the second adapting surface 102 of the adapter device 1 is used for connecting the fourth switching disc 31 of the tool 3;

thus, as shown with reference to fig. 2b, the adapter 1 is connected to the robot 2 on the one hand and to the tool 3 on the other hand. By means of the switching action of the switching device 1, the robot 2 can be connected to the tool 3 from the top of the tool 3.

In other words, the direct connection of the robot 2 with the tool 3 enables a connection gesture; the robot 2 and the tool 3 can be connected in another way by the switching action of the switching device 1.

Therefore, by adopting the switching device 1 provided by the embodiment of the present application, the robot 2 and the tool 3 can increase one connecting posture; thus, the working range of the robot 2 can be enlarged without increasing the number of tools 3; in the case of a tool 3 which is a welding jaw, the welding reach of the robot 2 is enlarged.

In addition, the cost of the adapter 1 is much lower than that of the tool 3, so by adopting the adapter 1 provided in the embodiment of the present application, the number of tools 3 can be saved, thereby reducing the operation cost.

Referring to fig. 1, a construction of a switching device 1 is shown: the adapter bracket 11 comprises a first adapter plate 111 and a second adapter plate 112, wherein one end of the first adapter plate 111 and one end of the second adapter plate 112 are connected with each other at a preset included angle;

an adapting space 110 is formed between the first adapting plate 111 and the second adapting plate 112, a surface of the first adapting plate 111 facing away from the adapting space 110 forms the first adapting surface 101, and a surface of the second adapting plate 112 facing toward the adapting space 110 forms the second adapting surface 102.

In this specific example, the adapter bracket 11 is composed of a first adapter plate 111 and a second adapter plate 112 that are connected to each other, and the first adapter plate 111 and the second adapter plate 112 are connected to each other at a predetermined angle.

As described above, when the robot 2 and the tool 3 are connected by the adapter 1, it is possible to realize a connection posture in which the robot 2 is connected to the tool 3 from the top of the tool 3; in this connection posture, when a predetermined angle between the first adapter plate 111 and the second adapter plate 112 is changed, the connection posture of the robot 2 and the tool 3 can be slightly adjusted.

For example, when the predetermined angle is 90 °, the transfer bracket 11 is L-shaped, and compared with the robot 2 directly connected to the tool 3, the robot 2 and the tool 3 realize 90 ° lateral transfer through the transfer device 1; when the preset included angle is 45 degrees, compared with the robot 2 and the tool 3 which are directly connected, the robot 2 and the tool 3 realize 45-degree lateral switching through the switching device 1. Optionally, the predetermined included angle is in the range of 30 ° to 180 °.

When the predetermined angle is 180 °, the adapting bracket 11 is flat, and when the adapting bracket 11 is used to connect the robot 2 and the tool 3, the posture of the robot 2 connected to the tool 3 cannot be changed, but the position of the robot 2 connected to the tool 3 can be adjusted, so that the working range of the tool 3 can be adjusted as well.

When the robot 2 is connected to the tool 3 via the adapter 1, the tool 3 is located in the adapter space 110 formed between the first adapter plate 111 and the second adapter plate 112 and is connected to the second adapter plate 112, while the robot 2 is connected to the first adapter plate 111 on the side of the first adapter plate 111 facing away from the adapter space 110.

an adapter space 110 is formed among the first adapter plate 111, the connecting plate 113 and the second adapter plate 112, the surface of the first adapter plate 111 facing away from the adapter space 110 forms the first adapter surface 101, and the surface of the second adapter plate 112 facing toward the adapter space 110 forms the second adapter surface 102.

In this specific example, the adaptor bracket 11 has another shape, and therefore, by adopting the adaptor device 1 including the adaptor bracket 11, another connection posture of the robot 2 and the tool 3 can be achieved.

For example, when the first adapter plate 111 and the second adapter plate 112 are both connected vertically to the connecting plate 113, the robot 2 and the tool 3 are laterally connected by 180 ° by the adapter device 1, as compared with the case where the robot 2 is directly connected to the tool 3.

Of course, according to the actual use requirement, the first adapter plate 111 and the second adapter plate 112 may be connected with the connecting plate 113 at an acute angle or at an obtuse angle; a first included angle is formed between the first adapter plate 111 and the connecting plate 113, and a second included angle is formed between the second adapter plate 112 and the connecting plate 113; the first included angle and the second included angle may be the same or different.
