[0003] In the prior art, on an automatic loading and unloading production line, when a mechanical robot needs to be repaired at a certain workstation, or a supporting component at the workstation fails and reports an error, etc., and mechanical maintenance needs to be carried out by stopping the machine. In order to ensure the continuous production of the entire production line, manual loading and unloading is required at the workstation where maintenance is stopped, that is, a manual operation mode is adopted to ensure the normal operation of the production line. However, due to the large floor space occupied by the mechanical robot, the space occupied by personnel at the stopped workstation is small, and it cannot ensure that there are enough personnel to replace the robot for operation, resulting in heavy workloads for personnel and low production efficiency.

[0028] In addition, limit seats 6 are fixedly installed on the carrier 1 of this embodiment at the first working position and the second working position respectively.

[0030] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that a driving motor (not shown) is provided on the carrier of Embodiment 2, and the power end of the driving motor is connected to the mounting plate for driving the mounting plate to slide along the guide rail.

[0031] Working principle: Before using the robot working position switching device of this embodiment, the operator performs the leveling operation of the carrier according to the horizontal condition of the installation ground of the working position. Adjust the leveling bolts of the leveling components at the corresponding positions separately to adjust the carrier to a suitable level. Then, according to the size of the mounting plate and the requirements of loading and unloading, components such as a brake chute seat, a limit block, and a position sensor are installed on the carrier, and the sliding debugging of the mounting plate is carried out to ensure the accuracy of the robot position when the mounting plate slides between the two working positions.

[0032] When the robot working position switching device of this embodiment is in use, when the mounting plate is at the first working position, the robot is used for automatic mode loading and unloading. When a robot failure or other equipment needs to be maintained, it is necessary to switch to the manual mode for loading and unloading. During the switching, the operator first rotates the fixed handle to release the brake block from the brake chute seat, and then drives the mounting plate to slide towards the second working position by pushing and pulling the handle or driving the motor. When the mounting plate slides and abuts against the limit block at the second working position, it is confirmed that the mounting plate reaches the second working position. Then the operator locks the fixed handle again, and the robot or equipment can be maintained. At the same time, the first working position can continue to perform loading and unloading in the way of manual operation. After the maintenance is completed, repeat the above steps to slide the mounting plate to the first working position, and the automatic mode can be switched. It should be noted here that when the mounting plate returns to the first working position, it can be automatically sensed by the position sensor to ensure the accurate positioning of the mounting plate. At the same time, when the mounting plate slides close to the limit block, the buffer is used to achieve early deceleration and buffering to ensure the stable movement of the machine equipment on the mounting plate and avoid damage to the machine due to inertia.
