That is, the rubber's ability to eliminate mechanical vibration is used to reduce shock, silence and reduce the harm caused by impact. Shock-absorbing rubber is widely used in various motor vehicles, equipment and instruments, automated office facilities and household appliances.

[0003] In order to save workpiece storage space, rubber shock-absorbing blocks are usually placed regularly in trays during processing, and multi-layer trays are stacked for storage. When the next processing step is required, the stacked trays are usually unstackered and the single-layer trays are transported to the side of the robot. The rubber blocks are taken out by the robot and transferred to the processing equipment for loading. During the operation, it is inconvenient to control the stop position of the tray after unstacking, and when the robot grabs the rubber block, the tray is easily touched by mistake and shifted, thereby affecting the next grabbing action of the robot, and then affecting the loading of the rubber block, affecting the processing efficiency.

Figure 2 As shown, the depalletizing mechanism 3 includes a mounting plate 301 fixed on the support frame 1, a lifting cylinder 302 is fixed on the mounting plate 301, a lifting plate 303 is fixed to the output end of the lifting cylinder 302, a pair of raised seats 304 are fixed to the top surface of the lifting plate 303, the pair of raised seats 304 are respectively located on both sides of the support frame 1, a fixing plate 305 is fixed to the top surface of the raised seat 304, a clamping cylinder 306 is fixed to the top surface of the fixing plate 305, an L-shaped clamping plate 307 is fixed to the output end of the clamping cylinder 306, a pair of clamping seats are formed on the inner side of the top surface of the L-shaped clamping plate 307, and a clamping groove matched with the clamping seat is provided on the side of the material tray.

[0027] A pair of guide seats 309 are fixed on the top surface of the fixed plate 305, and a guide shaft 308 penetrating the corresponding guide seat 309 is fixed on the outer side of the L-shaped clamping plate 307. When the clamping cylinder 306 is extended or retracted, the guide shaft 308 moves linearly in the guide seat 309, and the L-shaped clamping plate 307 can stably perform linear motion under the restriction of the guide shaft 308 and the guide seat 309. A limiting sleeve is also fixed on the mounting plate 301, and a limiting shaft penetrating the limiting sleeve is also fixed on the lifting plate 303. When the lifting cylinder 302 is extended or retracted, the limiting shaft moves linearly in the limiting sleeve, and the lifting plate 303 can stably perform linear motion under the restriction of the limiting sleeve and the limiting shaft.

[0028] When the stacked material tray is transported to the middle belt conveyor 2, the lifting cylinder 302 is pushed out, and the lifting plate 303 drives the L-shaped clamping plate 307 to move upward through the pad seat 304, and the clamping cylinder 306 is pushed out, and a pair of L-shaped clamping plates 307 move relative to each other until the clamping seat moves into the clamping slot, and the lifting cylinder 302 is pushed out again for a distance, and the bottom layer of the material tray can continue to be transported to the last group of belt conveyors 2, completing a depalletizing operation, and then passing through The lifting cylinder 302 retracts until the bottom material tray is supported by the middle belt conveyor 2, and the clamping cylinder 306 retracts.
