The mobile frame 201 is also fixedly connected with a second linear guide 203 and a second motor 204. The second linear guide 203 is provided with an alignment frame 205. The alignment frame 205 is provided with a docking track 206. The second motor 204 drives the alignment frame 205 to slide forward and backward along the second linear guide 203 relative to the mobile frame 201, so as to drive the docking track 206 to move forward to extend out of the mobile frame 201 and dock with other devices, or to move backward to retreat to the mobile frame 201. The alignment frame 205 is also fixedly connected with a third linear guide 207 and a third motor 208. The third linear guide 207 is provided with a grabbing mechanism 209. The third motor 208 drives the grabbing mechanism 209 to slide forward and backward along the third linear guide 207 relative to the alignment frame 205, so as to make the grabbing mechanism 209 approach and grab the plate rack vehicle (not shown) on other devices, and drag the plate rack vehicle along the docking track 206 to the alignment frame 205.

[0026] See also Figure 1 and Figure 4 In this embodiment, a first coordinate sensor 1011 is provided on the first linear guide rail 101, and a first coordinate positioning member 1012 is provided at the bottom of the mobile frame 201. The first coordinate sensor 1011 is located on the moving path of the first coordinate positioning member 1012 to provide the coordinate information of the transfer mechanism 200 to the central controller. The central controller accurately controls the travel of the mobile frame 201 on the first linear guide rail 101 through coordinate positioning, and then controls the travel distance of the transfer mechanism 200 on the track mechanism 100 according to the actual required distances between different devices. There is no need to set many mechanical limit structures, which further optimizes the design space and cost.

[0027] See also Figure 1-Figure 3In this embodiment, a first wheel belt assembly 210 is provided on the movable frame 201, and the first wheel belt assembly 210 includes a first circulating wheel belt 2101. The alignment frame 205 is fixedly connected to one side of the first circulating wheel belt 2101 through a chuck, and the movable end of the second motor 204 is connected to the first wheel belt assembly 210. The second motor 204 rotates forward / reverse to drive the first circulating wheel belt 2101 to rotate forward / reverse, thereby driving the alignment frame 205 to slide back and forth along the second linear guide rail 203 relative to the movable frame 201.

[0028] See also Figure 3 and Figure 5 In this embodiment, a second coordinate sensor 2011 is provided on the moving frame 201, and a second coordinate positioning member 2012 is provided on the alignment frame 205. The second coordinate sensor 2011 is located on the moving path of the second coordinate positioning member 2012 to provide coordinate information of the alignment frame 205 to the central controller. The central controller controls the second motor 204 through the coordinate information to drive the alignment frame 205 to move forward to a set position, or to drive the alignment frame 205 back to an original position.

[0029] See also Figure 5 and Figure 6 In this embodiment, a second wheel belt assembly 211 is provided on the alignment frame 205, and the second wheel belt assembly 211 includes a second circulating wheel belt 2111. The grabbing mechanism 209 is fixedly connected to the second circulating wheel belt 2111, and the movable end of the third motor 208 is connected to the second wheel belt assembly 211. The third motor 208 rotates forward / reverse to drive the second circulating wheel belt 2111 to rotate forward / reverse, thereby driving the grabbing mechanism 209 to slide back and forth along the third linear guide rail 207 relative to the alignment frame 205, approaching and grabbing the plate rack on other devices, and driving the plate rack to move to the alignment frame 205 through the docking track 206.

[0030] It should be noted that, in this embodiment, the grabbing mechanism 209 includes a grabbing cylinder and a grabbing head. The grabbing cylinder is electrically connected to the central controller, and the central controller controls the grabbing cylinder to drive the grabbing head to grab / release the pallet truck.

[0031] More specifically, in this embodiment, a third coordinate sensor 2051 is provided on the alignment frame 205, and a third coordinate positioning member 2052 is provided on the grasping mechanism 209. The third coordinate sensor 2051 is located on the moving path of the third coordinate positioning member 2052 to provide the coordinate information of the grasping mechanism 209 to the central controller. The central controller controls the third motor 208 to drive the grasping mechanism 209 forward / backward to the specified position through the second circulating wheel belt 2111 to grasp / release the plate rack car.

[0032] More specifically, in the present embodiment, two gripping mechanisms 209 are provided, and the two gripping mechanisms 209 are respectively fixedly connected to the opposite sides of the second circulating belt 2111, and the second circulating belt 2111 drives the two gripping mechanisms 209 to keep moving in opposite directions. The travels of the two gripping mechanisms 209 partially overlap, and in the overlapping part, the two gripping mechanisms complete the handover of the pallet truck. This can avoid the problem that the pallet truck cannot be towed back to the specified position of the alignment frame 205 due to the presence of a blind spot in the travel of one gripping mechanism; in short, one gripping mechanism 209 first grabs the pallet truck and drags it to the 1 / 3-2 / 3 position of the alignment frame 205, and then another gripping mechanism 209 grabs the pallet truck and completes the subsequent travel. This can avoid the blind spot in the travel of one gripping mechanism 209.

[0033] More specifically, in this embodiment, the alignment frame 205 is provided with an in-position sensor 212 , which is located near the front and rear ends of the docking track 206 to sense whether the plate rack vehicle has moved to a position.

[0034] It should be noted that all control instructions of the automatic transmission device are issued by the central controller, and all the above-mentioned motors, cylinders, sensors, etc. are electrically connected to the central controller.

[0035] The following is a unified description of the operating steps of the automatic transmission device of this embodiment. First, the track mechanism 100 passes through different devices on several production lines, and the transfer mechanism 200 stops in front of a device. The central controller controls the alignment frame 205 to extend to approach the device, and aligns and connects through the docking track 206. The grabbing mechanism 209 moves forward, approaches and grabs the pallet trolley on the device, and then drags the pallet trolley along the docking track 206 to the alignment frame 205. The two middle grabbing mechanisms 209 are connected. After the pallet trolley is in place, the second grabbing mechanism 209 maintains a gripping and positioning state, and the alignment frame 205 retreats to the mobile frame 201. Then the mobile frame 201 moves on the track mechanism 100 to the next device. The central controller controls the above steps to be performed in reverse again to transfer the pallet trolley to the device, thereby completing the automatic transmission of the pallet trolley.
