DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0025] refer to Figures 1 to 5 A double-layer feeding workstation includes a workbench 2, an upper conveyor belt 3, a lower conveyor belt 4, a visual inspection component 5, a flipping component 6, and a multi-axis robot 10. A controller 12 is provided on the workbench 2. The multi-axis robot 10, the upper conveyor belt 3, the lower conveyor belt 4, the visual inspection component 5, and the flipping component 6 are all electrically connected to the controller 12 and controlled by it. Preferably, the controller 12 can be a teaching pendant.

[0026] Both the upper and lower conveyor belts 3 and 4 are motor-driven belt conveyors, known from the prior art and not described in detail here. The top surfaces of the upper and lower conveyor belts 3 and 4 serve as work surfaces for placing parts 1. A support 201 is provided on the workbench 2, with the upper and lower conveyor belts 3 and 4 spaced apart from each other on the support 201. A gap is left between the upper and lower conveyor belts 3 and 4 for the passage of parts 1. The conveying direction of the upper conveyor belt 3 is opposite to that of the lower conveyor belt 4. The upper conveyor belt 3 is shorter than the lower conveyor belt 4, and both ends of the lower conveyor belt 4 extend beyond the upper conveyor belt 3.

[0027] The visual inspection component 5 includes a stand 51 detachably connected to both sides of the upper conveyor belt 3, a protective cover 52 arranged on the top of the stand 51 and with the opening facing downward, and a detection camera 53 arranged in the protective cover 52. The detection end of the detection camera 53 corresponds to the working surface of the upper conveyor belt 3 to inspect the parts 1 at the discharge end of the upper conveyor belt 3.

[0028] The operating end of the multi-axis robot 10 is a shoulder-pole-shaped flange, and two symmetrically mounted handling grippers 11 are mounted on this end. The movable ends of these grippers 11 are three-finger retractable grippers, which can grip either the forward end 101 or the reverse end 102 of a component 1. Driven by the multi-axis robot 10, the grippers 11 are moved to the discharge end of the upper conveyor belt 3 or the feed end of the lower conveyor belt 4.

[0029] The upper conveyor belt 3 and the lower conveyor belt 4 are both provided with two relatively arranged limiting mechanisms 7. The limiting mechanisms 7 include side baffles 71 and at least one mounting member 72. The length of the upper conveyor belt 3 is adapted to the length of its corresponding side baffles 71, and the length of the lower conveyor belt 4 is adapted to the length of its corresponding side baffles 71. The two opposite side baffles 71 are used to block the parts 1 from escaping from the upper conveyor belt 3 or the lower conveyor belt 4.

[0030] An adjusting rod 701 is provided between the side guard plate 71 and the mounting member 72. The axial direction of the adjusting rod 701 extends along the width direction of the upper conveyor belt 3. The mounting member 72 is provided with a snap ring 721. The first end of the adjusting rod 701 is provided on the side guard plate 71. The second end of the adjusting rod 701 is sleeved on the snap ring 721. The snap ring 721 is provided with a fastener 722 for fastening the adjusting rod 701. The fastener 722 is a bolt structure so as to adjust the distance between the corresponding two side guard plates 71 and improve the applicability of the upper conveyor belt 3 and the lower conveyor belt 4.

[0031] The infeed and outfeed ends of the upper conveyor belt 3 and the lower conveyor belt 4 are both equipped with sensing devices 8 for sensing parts 1. These sensing devices 8 comprise a laser emitter 81 and a laser receiver 82 arranged in opposing positions. Laser light emitted by the laser emitter 81 is received by the laser receiver 82, and the sensing devices 8 detect the presence of parts 1 in the area between the laser emitter 81 and the laser receiver 82. Preferably, both the laser emitter 81 and the laser receiver 82 are equipped with a first mounting plate 801, which can be removably attached to the side of the upper conveyor belt 3 or the side of the lower conveyor belt 4, allowing staff to adjust the position of the sensing devices 8 as needed.

[0032] When the workstation is in use, the component 1 is placed on the working surface of the feed end of the upper conveyor belt 3, and the upper conveyor belt 3 sends the component 1 to the discharge end of the upper conveyor belt 3 for the visual inspection component 5 to detect and complete the identification and positioning of the component 1. Two side baffles 71 with adjustable spacing are provided on the upper conveyor belt 3 and the lower conveyor belt 4, so that the space between the two side baffles 71 can adapt to components 1 of different sizes. The sensing device 8 is spaced apart from the two side baffles 71 close to it to avoid the limit mechanism 7 adjusting the spacing between the two side baffles 71 to interfere with the work of the sensing device 8; when any of the two sensing devices 8 of the upper conveyor belt 3 senses the component 1, the upper conveyor belt 3 stops so that the upper conveyor belt 3, multiple parts 1 are placed on the feeding side of the upper conveyor belt 3, and the visual inspection component 5 is convenient for identifying and positioning the upper parts 1 on the discharging end of the upper conveyor belt 3, so that the multi-axis robot 10 can place the parts 1 in sequence on the feeding end of the lower conveyor belt 4 through the carrying clamping claws 11; when any one of the two sensing devices 8 of the lower conveyor belt 4 senses the part 1, the lower conveyor belt 4 stops, and the upper conveyor belt 3 and the lower conveyor are adapted to different parts 1 through the limiting mechanism 7, and detect whether the part 1 is in place through the sensing device 8 arranged at intervals from the limiting mechanism 7, so as to facilitate the multi-axis device person to move the part 1 on the upper conveyor belt 3 to the lower conveyor belt 4, thereby realizing efficient and accurate flexible loading.

[0033] The multi-axis robot 10 moves the component 1 to the feed end of the lower conveyor belt 4. The lower conveyor belt 4 then delivers the inspected component 1 to its discharge end. A cross baffle 9 is provided at the discharge end of the lower conveyor belt 4. Second mounting plates 901 are detachably attached to both sides of the bottom of the cross baffle 9. The bottom of the cross baffle 9 is spaced apart from the working surface of the lower conveyor belt 4. The cross baffle 9 prevents the component 1 from escaping the discharge end of the lower conveyor belt. The feed end of the upper conveyor belt 3 and the discharge end of the lower conveyor belt 4 are located on the same side. The workstation uses manual or mechanical methods to retrieve and place components 1.

[0034] The flipping assembly 6 includes a mounting frame 61, a lifting drive device 62, a positioning plate 63, a flipping drive device 64, a flipping plate 65, and a flipping clamping claw 66. The mounting frame 61 is fixedly connected to the workbench 2, and the lifting drive device 62 and the flipping drive device 64 are arranged at intervals on the top surface of the mounting frame 61. The lifting end of the lifting drive device 62 is connected to the positioning plate 63. Preferably, the lifting drive device 62 is a telescopic cylinder to move the positioning plate 63 to a position corresponding to the discharge end of the upper conveyor belt 3.

[0035] The top surface of the positioning plate 63 is respectively provided with a transfer placement position 631 and a flip placement position 632. The transfer placement position 631 is for the positive end 101 of the component 1 to be adapted and placed, and the flip placement position 632 is for the reverse end 102 of the component 1 to be adapted and placed. The flip drive device 64 is a side cylinder. The movable end of the flip drive device 64 is connected to the flip plate 65. The flip clamping claw 66 is provided on the flip plate 65, and the flip clamping claw 66 is used to clamp the positive end 101 or the reverse end 102 of the component 1. The flip drive device 64 drives the flip plate 65 to perform a 360° flipping movement so that the flip clamping claw 66 corresponds to the flip placement position 632, which is used to flip the component 1.

[0036] The multi-axis robot 10 can also move the component 1 to the flipping assembly 6 for flipping through the carrying clamping claw 11. The multi-axis robot 10 can move the flipped component 1 to the discharge end of the upper conveyor belt 3 through the carrying clamping claw 11 for the visual inspection component 5 to inspect the component 1, completing the appearance inspection of the positive end 101 and the reverse end 102 of the component 1. The multi-axis robot 10 transfers the component 1 to the feed end of the lower conveyor belt 4 in the correct position, so that the component 1 completes flexible loading in the correct position. In this process, the flipping and transfer of the component 1 does not require manual operation, the labor cost is low, and the inspection efficiency is high.

[0037] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
