The conveying assembly 500 is arranged on the bearing platform 300 and is drivingly connected with the moving end of the conveying driving mechanism 400.

[0039] Specifically, when the workpiece transfer platform provided by the embodiment is used, the workpiece is placed on the bearing platform 300. Since the bearing platform 300 is installed on the mobile base 100, the movement of the mobile base 100 can drive the bearing platform 300 to move together, so as to realize the position conversion of the workpiece.

[0040] After the mobile base 100 moves to the side of the platform for processing the workpiece, the bearing platform 300 is driven by the platform moving mechanism 200 to move towards the platform for processing the workpiece. When the bearing platform 300 moves to the limit, the end of the bearing platform 300 is placed on the platform for processing the workpiece.

[0041] In the embodiment, the top of the mounting portion is provided with a slide 110. The bottom surface of the bearing platform 300 is provided with a sliding block 310, and the sliding block 310 is arranged in the slide 110, so that the bearing platform 300 is in sliding fit with the mobile base 100.

[0042] The slide 110 can guide the sliding direction of the sliding block 310, and the sliding block 310 moves along the inner wall of the slide 110 under the action of the platform driving mechanism, so that the bearing platform 300 can realize directional movement under the cooperation of the sliding block 310 and the slide 110, and the movement of the bearing platform 300 is guided.

[0043] In the embodiment, the slide 110 and the sliding block 310 are both multiple. The multiple slides 110 are arranged in parallel and at intervals, and the multiple sliding blocks 310 are arranged in one-to-one correspondence with the multiple slides 110.

[0044] The structure line of the multiple slides 110 arranged in parallel can guide the moving direction of the sliding block 310, and can also avoid the rotation of the bearing platform 300 during the movement, so that the discharge direction of the bearing platform 300 is changed.

[0045] Specifically, the slide 110 and the sliding block 310 in the embodiment are both four, the four slides 110 are arranged in parallel at intervals, and the four sliding blocks 310 are respectively inserted in the four slides 110, and the four sliding blocks 310 slide in the four slides 110 when the bearing platform 300 moves.

[0046] In the embodiment, the platform moving mechanism 200 includes a rotary motor 210 and a transmission screw 220. The rotary motor 210 and the transmission screw 220 are arranged between two adjacent slides 110, the driving end of the rotary motor 210 is in transmission connection with the transmission screw 220, the transmission screw 220 is arranged in parallel with the slide 110, and the transmission screw 220 is in transmission connection with the bearing platform 300.

[0047] Specifically, the rotary motor 210 in the embodiment is arranged between the two middle slides 110, and the transmission screw 220 is also arranged between the two middle slides 110. After the transmission screw 220 is connected with the bearing platform 300, the weights on both sides of the connection between the bearing platform 300 and the transmission screw 220 are balanced, and the structure on both sides of the bearing platform 300 is not subjected to uneven stress when the bearing platform 300 is driven to move.

[0048] In the embodiment, the bearing platform 300 is provided with a transmission groove 320. Referring to Figure 3 , the extension direction of the transmission groove 320 is the same as the driving direction of the platform moving mechanism 200.

[0049] Specifically, the transmission groove 320 is used to arrange the rack 420 for driving the conveying assembly 500 to move, the rack 420 is laid in the transmission groove 320, and the transmission direction of the rack 420 is the same as the driving direction of the transmission screw rod 220. The driving motor 410 can realize the movement along the extension direction of the rack 420 under the meshing action of the gear rack 420, thereby driving the conveying assembly 500 to move together. In this structure, the movement direction of the conveying assembly 500 on the bearing platform 300 is the same as the movement direction of the bearing platform 300. When it is needed to push the workpiece on the bearing platform 300, the bearing platform 300 carries the conveying driving mechanism 400, the conveying assembly 500 and the workpiece to move together, and when the bearing platform 300 is placed on the platform for processing the workpiece at the end, the first pushing is completed. The driving motor 410 drives the driving conveying assembly 500 to move along the rack 420 to the platform for processing the workpiece, thereby pushing the workpiece on the bearing platform 300 to the platform for processing the workpiece, realizing the second pushing of the workpiece. The workpiece is pushed twice by the bearing platform 300 and the conveying assembly 500 in this embodiment, thereby improving the pushing distance of the workpiece, and after the pushing, the conveying assembly 500 and the bearing platform 300 can perform the resetting action, thereby reducing the floor space of the workpiece running platform.

[0050] In this embodiment, the conveying assembly 500 comprises an electro-permanent magnetic chuck. The electro-permanent magnetic chuck faces the movement direction of the bearing platform 300.

[0051] The electro-permanent magnetic chuck adopts the electric pulse control of the “on” and “off” of the magnetic force, realizes the quick and flexible adjustment of the magnetic force, not only has the strong adsorption force of the permanent magnetic chuck, but also realizes the accurate control of the magnetic force through the electric control mode, so that the connection and separation of the workpiece can be completed in a very short time (less than 1 second). And, after the electro-permanent magnetic chuck is connected with the workpiece, the five-surface processing can be realized in the connected state, which is very convenient to use and simple to assemble and disassemble.

[0052] As an implementable way, the conveying assembly 500 can also realize the connection and fixation with the workpiece through the taking gripper. When the taking gripper is used, the connecting frame is used in cooperation with the taking gripper, one side of the connecting frame abuts against the workpiece, and the gripper bodies of the taking gripper are respectively arranged on the two sides of the abutting surface and perform the clamping action towards the middle, so as to clamp and fix the workpiece on the connecting frame, so that the conveying driving mechanism 400 drives the connecting frame to move to push the workpiece to the preset position.

[0053] In this embodiment, the workpiece transfer platform further comprises an auxiliary supporting assembly. The auxiliary supporting assembly comprises a supporting frame and a rolling supporting piece, the supporting frame is arranged on one side of the moving base 100 and located on the movement path of the bearing platform 300. The rolling supporting piece is arranged on the top of the supporting frame for abutting against the bottom surface of the bearing platform 300.

[0054] When the workpiece is pushed, in order to avoid that the length of the bearing platform 300 is too long, the bearing platform 300 is lowered when moving to the platform of the machining workpiece, and the embodiment realizes auxiliary support of the bearing platform 300 through the support frame and the rolling support. The bottom surface of the bearing platform 300 is in abutment with the rolling support, and the rolling support rotates during the movement of the bearing platform 300 to avoid wear due to excessive friction.

[0055] In the embodiment, a screw elevator is arranged on the moving base 100. The moving end of the screw elevator is in transmission connection with the mounting portion.

[0056] The screw elevator is used to adjust the height of the mounting portion, so as to adjust the height of the bearing platform 300, so that the top surface height of the bearing platform 300 can be leveled with the top surface height of the platform of the machining workpiece, and the workpiece can be smoothly pushed onto the blanking platform.

[0057] In the embodiment, a rotating mechanism is arranged on the moving base 100. The rotating mechanism is arranged at the bottom of the moving base 100, and the rotating mechanism is in transmission connection with the mounting portion.

[0058] The rotation can adjust the angle of the mounting portion, so as to adjust the orientation angle of the bearing platform 300. When the moving base 100 reaches the specified position to push the workpiece, the angle of the bearing platform 300 can be adjusted by the rotating mechanism, so that the conveying assembly 500 can accurately push the workpiece onto the platform of the machining workpiece.

[0059] The workpiece production system provided in the embodiment includes a machining equipment workbench, a moving track, and a workpiece transfer platform.

The workpiece transfer platform is arranged on the moving track, and the moving base 100 of the workpiece transfer platform cooperates with the moving track to move along the moving track, and the bearing platform 300 of the workpiece transfer platform can cooperate with the lap joint portion.

[0060] Specifically, the machining table is the platform of the machining workpiece. When the workpiece transfer platform moves to the position opposite to the machining table along the moving track, the bearing platform 300 moves to the machining table under the driving of the platform moving mechanism 200, and then the conveying assembly 500 moves to the machining table under the driving of the conveying driving mechanism 400 to push the workpiece, until the workpiece is pushed out of the bearing platform 300 and falls on the preset position of the machining table, so as to realize the transfer and pushing of the workpiece.

[0061] It should be noted that the moving mechanism 200 in the embodiment can also adopt other transmission structures such as chain transmission and gear and rack transmission, and can also achieve conveying and transferring of the bearing platform.

[0062] Correspondingly, the driving mechanism 400 in the embodiment can also be replaced by a chain transmission or a screw transmission.
