[0040] like Figure 5As shown, in this embodiment, the gate piece 22 includes a handle 221; the second grasping mechanism 12 includes a pair of clamping blocks 121 and a second grasping driver 122. When the second grasping mechanism 12 grasps the gate piece 22, the second grasping driver 122 drives the clamping blocks 121 to engage so as to clamp the handle 221 between the pair of clamping blocks 121. In this embodiment, the second grasping mechanism 12 is a pneumatic clamp, that is, the second grasping driver 122 is a finger cylinder, and the clamping block 121 is installed on a pair of opening and closing movable parts of the finger cylinder, and a clamping cavity adapted to the handle 221 is provided between the pair of clamping blocks 121.

After the product part 21 and the gate part 22 are separated, when the product part 21 and the gate part 22 are respectively picked up, the rotating seat 14 is used to drive the mounting plate 13 to rotate to switch the first gripping mechanism 11 and the second gripping mechanism 12. Specifically, the first gripping mechanism 11 and the second gripping mechanism 12 are arranged on both sides of the mounting plate 13 corresponding to the rotation center of the rotating seat 14, and the rotating seat 14 rotates 180° to complete the switching of the first gripping mechanism 11 and the second gripping mechanism 12.

[0042] like Figure 8As shown, in this embodiment, the cutter assembly 33 includes a pair of cutters 331 and a cutter driving device 332, and the blades of the pair of cutters 331 are opposite to each other; when the transfer platform 31 moves to the first preset position, the pair of cutters 331 are on the upper and lower sides of the connection point between the side wall of the through groove 210 and the gate member 22, and the cutter driving device 332 is used to drive the pair of cutters 331 to move together to cut off the connection point between the through groove 210 and the gate member 22; the transfer platform 31 is provided with a through cavity 310 for the cutter 331 to pass through the transfer platform 31 when performing the gate cutting operation.

Specifically, the cutter 331 is provided with an electric heating element, and the product part 21 and the gate part 22 are efficiently separated by a hot cutting process. It should be noted that in the reset state, the pair of cutters 331 are separated by a preset distance to ensure that the transfer platform 31 can pass between the pair of cutters 331 during the movement.

[0043] like Figure 6 As shown, in this embodiment, the first moving module 32 includes a first translation drive cylinder 322 and a pair of fixed slide rails 321, the transfer platform 31 is slidably mounted on the slide rails 321, and the first translation drive cylinder 322 is in transmission connection with the transfer platform 31.

[0044] like Figure 1 As shown, in this embodiment, the number of the injection molding devices is 2, and the transfer robot 1 is arranged between a pair of injection molding devices.

The vertical driving device 541 is used to vertically move the weighing sensor 54, so that a bearing surface of the weighing sensor 54 switches and moves between the upper and lower sides of the upper end surface of the receiving table 52. When the weighing sensor 54 moves to the upper side of the receiving table 52, the upper end surface is used to support the product part 21 transferred from the gate separation device 3. The product receiving device 5 is used to receive the product parts 21. In the reset state, the receiving platform 52 is at the third preset position, and a pair of weighing sensors 54 are on the upper side of the receiving platform 52. After the product parts 21 are transferred to a pair of weighing sensors 54, the product parts 21 are weighed and measured to ensure that the weight of the product parts 21 is within the preset error range. If the weight of the product parts 21 exceeds the tolerance, the transfer robot 1 transfers the product parts 21 out of the product receiving device 5 for rejection. If the weight of the product parts 21 does not exceed the tolerance, the vertical drive device 541 descends to move the upper end of the weighing sensor 54 to the bottom of the end face of the receiving platform 52. At this time, the product parts 21 are placed on the receiving platform 52. Finally, the second moving module 53 drives the receiving platform 52 to move to the fourth preset position for receiving. The receiving operation can be realized by manual operation. The vertical drive device 541 is a pair of cylinders. The second movable module 53 includes a sliding seat 531 connected to the fixed platform 51 through a guide rail-slider, the material receiving platform 52 is arranged on the sliding seat 531, and the second movable module 53 also includes a second translation drive cylinder 532, and the movable component of the second translation drive cylinder 532 is connected to the sliding seat 531.
