Each handling unit corresponds to a plate handling station. By arranging multiple handling units on the top support plate 1, multiple plates can be handled simultaneously.

[0025] like Figures 2 to 4 As shown, each transport unit includes a first distance changing mechanism 2 and a second distance changing mechanism 3 arranged in a horizontal direction, and the output ends of the first distance changing mechanism 2 and the second distance changing mechanism 3 are each provided with at least one pair of clamps 4, and the pair of clamps 4 can move relatively along the first distance changing direction or the second distance changing direction driven by the first distance changing mechanism 2 or the second distance changing mechanism 3 to clamp the material from both sides of the plate material; wherein the first distance changing direction is perpendicular to the second distance changing direction, and the clamps 4 are located in the same clamping plane, so that the two pairs of clamps 4 can clamp the plate material from four side directions respectively.

[0026] The transport unit further comprises a lifting mechanism 7, and the first distance-changing mechanism 2 is arranged at a vertical movement output end of the lifting mechanism 7, so as to realize the movement of the first distance-changing mechanism 2 in the vertical direction.

[0027] The utility model utilizes a liftable first pitch-changing mechanism 2 to drive at least one pair of clamping jaws 4 to move vertically from an initial position to the bottom of a material, and the clamping jaws 4 on the first pitch-changing mechanism 2 move toward each other to position the side of the product; the lifting mechanism 7 then rises to the initial clamping position, and at the same time limits the clamping surface of the clamping jaws 4 on the second pitch-changing mechanism 3. At this time, the second pitch-changing mechanism 3 is started, driving the clamping jaws 4 on the second pitch-changing mechanism 3 to move toward each other, and clamping and positioning are performed from another side of the product.

[0028] Specifically, Figure 2 As shown, each transport unit includes an upper support plate 5 and a lower support plate 6 with vertical relative positions, wherein the first distance changing mechanism 2 is connected to the lower support plate 6, and the second distance changing mechanism 3 is connected to the upper support plate 5; the lifting mechanism 7 is fixedly arranged on the support plate, and the moving end of the lifting mechanism 7 is fixedly connected to the lower support plate 6, and the lifting mechanism 7 drives the lower support plate 6 to move, thereby realizing the vertical movement of the first distance changing mechanism 2.

[0029] In this embodiment, the first pitch changing mechanism 2 and the second pitch changing mechanism 3 respectively include a first clamping cylinder 21 and a second clamping cylinder 31, and each pair of clamping jaws 4 is connected to the moving output end of the first clamping cylinder 21 through a first cylinder bracket 22 or is connected to the moving output end of the second clamping cylinder 31 through a second cylinder bracket 32, so as to realize the relative movement of each pair of clamping jaws 4.

[0030] In this embodiment, the lifting mechanism 7 is a push-pull cylinder 71, and the output shaft of the push-pull cylinder 71 is fixedly connected to the lower support plate 6. Furthermore, a plurality of guide rods 72 are vertically arranged on the lower support plate 6, and a linear bearing 73 is fixedly provided at the position of the upper support plate 5 corresponding to the guide rod 72, and the guide rod 72 is inserted into the linear bearing 73, and the vertical stroke of the lifting mechanism 7 is limited by the cooperation between the guide rod 72 and the linear bearing 73.

[0031] Furthermore, a second guide rail 33 is fixedly provided at the bottom of the upper support plate 5 along the second pitch changing direction, and the second cylinder bracket 32 ​​is slidably connected to the second guide rail 33 to guide the pitch changing direction of the second cylinder; similarly, a first guide rail 23 is fixedly provided at the bottom of the lower support plate 6 along the first pitch changing direction, and the first cylinder bracket 22 is slidably connected to the first guide rail 23.

In this embodiment, there are two pairs of clamping jaws 4 arranged on the first pitch change mechanism 2, which are respectively located at the two ends of the lower support plate 6 along the second pitch change direction, and are positioned from both ends of the product, so that the center of gravity of the product during the clamping process is concentrated in the middle of the two pairs of clamping jaws 4, thereby effectively preventing the product from falling; at this time, the clamping jaws 4 on the second pitch change mechanism 3 move again to complete the clamping and positioning of the product.

The two groups of transport units are respectively connected to the output ends of the third pitch-changing mechanism 8 and can move relatively along the pitch-changing direction of the third pitch-changing mechanism 8. As described above, the two groups of transport units correspond to the two groups of transport stations respectively, and the function of the third pitch-changing mechanism 8 is to adjust the relative position between the two groups of transport units.

[0034] In this embodiment, the third pitch-changing mechanism 8 includes a third clamping cylinder 81 fixedly connected to the bottom of the top support plate 1, and the two groups of handling units are respectively connected to the two pneumatic output ends of the third clamping cylinder 81. Furthermore, a longitudinal connecting rod 82 arranged along the pitch-changing direction of the third pitch-changing mechanism 8 is provided on the top support plate 1, and a fixing block 83 is fixedly connected to the bottom of the two groups of handling units, and the longitudinal connecting rod 82 passes through the two groups of fixing blocks 83.

The top support plate 1 is connected to the rotation center axis 92 and is driven to rotate by the flipping mechanism 9, thereby realizing the rotation of the transport unit to any direction in the horizontal plane.

[0036] In this embodiment, the flipping mechanism 9 includes a rotating cylinder 91; and the flipping mechanism 9 is fixedly connected to an external three-axis moving module, so that the long-distance transmission of the transport unit and the materials clamped by the transport unit can be realized.

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
