Description

Technical Field

[0001] This invention relates to the field of positioning fixtures for machine tool processing, specifically to an intelligent detection device for fan impellers. Background Technology

[0002] The fan impeller is an integrated structure formed by injection molding. After injection molding, a series of tests are required, including surface defect testing, weighing testing, and balance testing. Traditionally, the injection-molded products are collected and transported to the testing equipment for testing. Furthermore, due to the irregular shape of the fan impeller, it is difficult to handle and transfer it. After testing, qualified and unqualified products need to be separated, and multiple fan impellers need to be repackaged. The irregular shape of the fan impeller increases the difficulty of transferring between testing stations and the subsequent automated packing operation. Often, manual intervention is required to complete the entire process, resulting in low automation and a low damage rate.

[0003] This invention proposes an intelligent detection device for fan impellers to solve the above-mentioned technical problems. Summary of the Invention

The lifting guide plate is fixed to the docking roller assembly, and the two side plates of the lifting guide plate rise and fall along the Z-axis slide rail. The lifting guide plate is fixed to the power output end of the lifting unloading module. Under the action of the lifting unloading module, the docking roller assembly docks with the upper roller of the double-layer roller box changer for unloading and with the lower roller for unloading, respectively.

[0016] The working principle is as follows:

[0017] After the fan impeller is formed in the injection molding machine, the feeding module moves in the X, Y, and Z directions to remove the formed workpiece. The image from the first CCD camera positions the workpiece, controlling the six-axis robot to move and pick it up. The second gripper cylinder at the end of the six-axis robot, under the action of the robotic arm, flips the fan impeller so that the positioning hole faces downwards. Weighing, surface imaging, and dynamic balance checks are then performed. If the weight is outside the set range, there are surface defects, or the dynamic balance is unqualified, the workpiece will be deemed unqualified. The six-axis robot will then transfer the workpiece to the waste collection bin. Qualified workpieces, after inspection, will be handled by the six-axis robot. The robot removes the workpiece from the inspection mechanism, flips it over, and then hands it over to the pick-up and flip gripper in the unloading module. After being gripped, it rotates 90° under the action of the servo mechanical gripper. The upper roller is used to transport empty product boxes, and the lower roller is used to transport full product boxes. The servo mechanical gripper drives the workpiece downward to be placed into the upper empty product box. After it is full, it moves downward to the lower roller under the action of the lifting cylinder in the lifting unloading module and runs in the opposite direction to the exit end. The exit end can be equipped with an AGV trolley platform of the same height as the lower roller for automatic transportation. The upper roller and the lower roller are driven by different servo motors.

[0018] The advantages are as follows:

[0019] (1) The intelligent fan impeller detection equipment involved in this invention is fully automated from injection molding, detection and diversion to packing and unloading, without the need for intermediate transfer, which greatly improves production efficiency;

[0020] (2) The intelligent fan impeller detection device of the present invention uses a six-axis robot as an intermediate transfer structure, which has a high degree of freedom of movement, does not require complex multi-part coordination, and saves internal space;

[0021] (3) The double-layer roller box changer in the intelligent fan impeller detection equipment of the present invention saves equipment space and shortens the length of the box packing line as much as possible, avoids inefficient idling, reduces equipment operating costs, and improves equipment compactness.

The ring light source 322 and the second CCD camera 323 are vertically aligned and both are fixed to the upper surface of the second profile support 321. The dynamic balancing detection component is a dynamic balancing machine.

[0035] The unloading module 5 includes an unloading support frame 51, a lifting unloading module 52, a Z-axis slide rail 53, a lifting guide plate 54, a docking roller assembly 55, a servo mechanical gripper 56, and a pick-up flipping gripper 57. The Z-axis slide rail 53, the lifting unloading module 52, and the servo mechanical gripper 56 are all mounted on the support plate surface of the unloading support frame 51. The pick-up flipping gripper 57 is rotatably connected to the power output end of the servo mechanical gripper 56. The servo mechanical gripper 56 is a gripper cylinder. The lifting guide plate 54 is fixed to the docking roller assembly 55, and the two side plates of the lifting guide plate 54 rise and fall along the Z-axis slide rail 53. The lifting guide plate 54 is fixed to the power output end of the lifting unloading module 52. Under the action of the lifting unloading module 52, the docking roller assembly 55 docks with the upper roller of the double-layer roller box changing machine 7 for unloading and with the lower roller for unloading, respectively.

[0036] The double-layer roller box changing machine 7 includes a roller box changing machine support 71, an upper roller 72, and a lower roller 73. The upper roller 72 and the lower roller 73 are respectively installed on the upper support and the lower support of the roller box changing machine support 71.

[0037] Specific Implementation Case 2:

[0038] Based on Implementation Case 1, one or more of the following optimization schemes are also included, for example:

[0039] It also includes a buffer station 9, which comprises a third profile support 91 and a second fan limiting mechanism 92, the second fan limiting mechanism 92 being fixed to the upper end face of the third profile support 91. The buffer station is used to temporarily store workpieces to be inspected for transfer.

[0040] The lifting and unloading module 52 includes a gear chain assembly 521 and a lifting cylinder 522 symmetrically installed on both sides of the unloading support frame 51.

[0041] The unloading module 5 also includes a side-positioning cylinder 58, whose piston shaft is connected to a positioning plate with a right-angle positioning groove. The right-angle positioning groove holds a right-angle edge of the product box and positions it at a right angle to prevent displacement during the unloading and filling process.

[0043] The buffer assembly also includes a proximity switch 64, which is fixed to the surface of the upper fixed plate 61 and is used to sense the rising height of the upper end of the bearing 63. During the feeding process, the fan impeller below tilts to the side, which will inevitably hinder the normal feeding and downward movement of the pick-up and flip gripper 57. This causes the lower buffer plate 62 to rise due to the thrust, and the upper end of the bearing rises synchronously and is sensed by the proximity switch 64, resulting in an emergency stop.

[0044] One or more limiting cylinders 74 are symmetrically installed on both sides of the upper roller 72. The distance between two adjacent limiting cylinders 74 is enough to place a product box. The installation position of the limiting cylinder 74 is close to one end of the unloading module 5 to prevent the product box used for loading from sticking to the previous product box.

[0045] It also includes a complete fence set at the outermost perimeter, which is composed of profile posts and PC panels, with safety locks installed on the PC panels at the entrances and exits.
