[0023] Embodiment 1

[0024] An anti-overshoot dual-layer cache platform, such as Figure 1-3 As shown, it includes a support frame 1, a driving device 2 and a lifting platform 3. The driving device 2 is installed on the top of the support frame 1 and connected to the lifting platform 3 to drive the lifting platform 3 to move in the vertical direction relative to the support frame 1. The lifting platform 3 includes a plurality of discharge buffers 31 and a plurality of feed buffers 32. The discharge buffer 31 is located above the feed buffer 32. A first anti-overrush blocking mechanism 4 is provided on one side of the discharge buffer 31. A second anti-overrush blocking mechanism 5 is provided on one side of the feed buffer 32. The first anti-overrush blocking mechanism 4 and the second anti-overrush blocking mechanism 5 are respectively located on both sides of the lifting platform 3.

[0025] Further, the driving device 2 includes a motor 21 and a screw rod 22, and the output end of the motor 21 is connected to the screw rod 22. The screw rod 22 is threadedly connected to the lifting platform 3. The motor 21 drives the screw rod 22 to rotate, and the lifting platform 3 moves along the screw rod 22.

[0026] Furthermore, if Figure 3 As shown, the first anti-overshoot blocking mechanism 4 includes an electric push rod 41, a connecting plate 42, a tension spring 43 and at least one limit stopper 44, wherein the electric push rod 41 is fixed to one side of the support frame 1. The upper part of the limit stopper 44 is rotatably connected to the lifting platform 3. The lower part of the limit stopper 44 is rotatably connected to the connecting plate 42. One end of the tension spring 43 is connected to the connecting plate 42, and the other end is connected to the lifting platform 3.

[0027] Furthermore, platform rollers 33 are provided on both the discharge buffer 31 and the feed buffer 32. This facilitates the movement of goods on the discharge buffer 31 and the feed buffer 32, and is beneficial for loading and unloading product goods. Furthermore, the transmission direction of the platform rollers 33 is parallel to the support frame 1.

[0028] Further, the stretching direction of the tension spring 43 is parallel to the moving direction of the connecting plate 42. It is ensured that the tension spring 43 can be stretched when the connecting plate 42 moves, which is conducive to the reset of the connecting plate 42.

[0029] Further, the structure of the first anti-overshoot blocking mechanism 4 is the same as that of the second anti-overshoot blocking mechanism 5. Further, the electric push rod 41 and the connecting plate 42 are located on the same side. The electric push rod 41 and the connecting plate 42 are arranged in a matching manner, and the connecting plate 42 can only be pushed to move when the electric push rod 41 is started.

[0030] Working principle:

[0031] like Figure 4 As shown, when the mobile handling robot RGV does not reach the lifting platform 3, the lifting platform 3 descends to the bottom, and the staff transports the products that have been assembled and wired to the discharge buffer 31. The first anti-overshoot blocking mechanism 4 is not activated, and the limit block 44 is in an upright state to prevent the product from sliding. When the mobile handling robot RGV reaches the lifting platform 3, the driving device 2 drives the lifting platform 3 to rise, and the feed buffer 32 rises to a certain height, which is convenient for RGV to transport the products to be assembled and wired to the feed buffer 32, and the second anti-overshoot blocking mechanism 5 is activated, which is convenient for the staff to transport the products from the feed buffer 32 to the workbench for assembly and wiring. Then the driving device 2 drives the lifting platform 3 to descend to the lowest point, the first anti-overshoot blocking mechanism 4 is activated, and the second anti-overshoot blocking mechanism 5 is not activated, the electric push rod 41 pushes the connecting plate 42 to move, the tension spring 43 is stretched, and the limit block 44 rotates to a horizontal position as the connecting plate 42 moves, which is convenient for RGV to move and remove the products that have been assembled and wired from the discharge buffer 31. After the RGV leaves the lifting platform 3, the electric push rod 41 contracts, the tension spring 43 is reset, and the connecting plate 42 is moved and reset, and the limit stopper 44 connected to one end of the tension spring 43 is driven to restore the upright state. The above operation is repeated throughout the entire production process.

[0032] In the entire production process, the operation signals between the equipment are coordinated by the MES management system of the entire production line. The driving device 2 drives the lifting platform 3 to move up and down only when there is a signal when the RGV arrives. The coordination between the first anti-overshoot blocking mechanism 4, the second anti-overshoot blocking mechanism 5 and the driving device 2 is controlled by PLC.

[0033] The utility model sets a discharging buffer and a feeding buffer to cache the incoming and outgoing goods, and the mobile handling robot RGV puts the goods in and takes them out from the lifting platform. Among them, the first anti-overrush blocking mechanism and the second anti-overrush blocking mechanism can prevent the goods from falling from the caching platform.

[0035] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
