[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the embodiments of the present invention include:

[0028] A disordered automatic feeding mechanism for cable materials, adopting a disordered material taking method, and its structure includes: a chassis 1, a feeding unit 2, a material receiving unit 3, a grasping unit 4, and a transfer platform 5. A feeding port is provided on the side wall of the chassis. The feeding unit is movably connected to the feeding port. The material receiving unit, the grasping unit, and the transfer platform are arranged in the chassis, and the grasping unit is arranged between the material receiving unit and the transfer platform.

[0029] The material receiving unit includes a material receiving conveyor belt 6 for receiving and conveying a product 99, a material receiving rack 7, a material receiving inductor 8 for detecting whether the product is in place, and a material receiving guiding baffle 9.

[0030] The material receiving conveyor belt can be directly arranged on the material receiving rack or on the side of the material receiving rack. One material receiving conveyor belt corresponds to a group of feeding units (one feeding trolley).

[0031] The material receiving guiding baffle is arranged on the material receiving rack, on the side of the material receiving conveyor belt, and the lower part of the material receiving guiding baffle inclines towards the center of the material receiving conveyor belt, so that the product can lean stably on the material receiving guiding baffle. When the product falls onto the material receiving conveyor belt, it will lean on the material receiving guiding baffle, which can not only prevent the product from falling off the conveyor belt, but also guide the form of the product to a certain extent, facilitating the manipulator to grasp it.

[0032] Meanwhile, in order to further prevent the product from slipping off the material receiving conveyor belt, a lateral baffle can be arranged on the other side of the material receiving conveyor belt, that is, the lateral baffle and the material receiving guiding baffle are respectively arranged on both sides of the material receiving conveyor belt.

[0033] The material receiving sensor is arranged on the material receiving rack and / or the material receiving conveyor belt. For the convenience of detection and improvement of efficiency, one feeding screw corresponds to one such material receiving sensor. When the material receiving sensor detects that the product moves onto the material receiving conveyor belt, the controller controls the manipulator to grasp according to the detection signal.

[0034] The grasping unit uses a 4-axis manipulator + rotating cylinder to realize the adjustment of the material form. Its structure includes a 4-axis manipulator 11, a rotating cylinder 12, a gripper 13, and a visual recognition device for identifying the form of the product material. The rotating cylinder is arranged on the manipulator, and the output shaft of the rotating cylinder is connected to the gripper and drives the gripper to rotate, so as to grasp and transport the product and adjust the front and back and angle of the product.

[0035] During use, the visual recognition device detects the form of the product material (the visual recognition device can directly adopt existing recognition instruments such as visual cameras). The form includes the front and back of the material and the angle of the material on the material receiving conveyor belt. The manipulator will grasp and adjust the product state according to the detection result. For example, if the product is in the reverse state, the manipulator grabs the product, rotates the gripper and then places the product on the material receiving conveyor belt, and then the manipulator grabs it again; if the product is in the front state, the manipulator directly places the product on the transfer platform and flows to the next station.

[0036] The feeding unit includes a feeding trolley 16, a feeding screw 17, a screw seat 18, a feeding screw groove 19, and a screw driving device 15 that drives the screw to rotate through friction.

[0037] The screw driving device includes a servo translation mechanism 21, a translation frame 22, a pressing cylinder 23, a lifting frame 24, a rotating motor 25, a synchronous pulley 26, a synchronous belt 27, a friction driving wheel 28, and a friction transmission wheel 20.

[0038] The servo translation mechanism is arranged at the upper part of the chassis and drives the translation frame to move back and forth. The pressing cylinder is arranged on the translation frame, and the pressing cylinder drives the lifting frame to move up and down. The friction drive wheel is movably arranged on the lifting frame through a wheel shaft. The rotating motor is arranged on the lifting frame. Synchronous wheels are arranged on the output shaft of the rotating motor and one or more of the wheel shafts, and the synchronous wheels are connected by a synchronous belt, so that the rotating motor drives the friction drive wheel to rotate axially on the lifting frame.

[0039] The loading trolley is movably connected to the loading port. When loading is required, the loading trolley can be directly pushed into the loading port, so that the end of the loading screw is located above the receiving unit and the drive wheel in the screw drive device is located above the transmission wheel.

[0040] The friction drive wheel is in contact with the friction transmission wheel, so that the friction drive wheel can drive the friction transmission wheel to rotate through friction, thereby driving the loading screw to rotate.

[0041] The screw seat is arranged on the top surface of the loading trolley. One side of the loading screw connected with the friction transmission wheel is movably connected to the screw seat. A spiral feeding screw groove is arranged on the loading screw to realize automatic sorting and feeding of the junction boxes and temporary storage of materials by using the screw feeding principle. The feeding screw groove is movably connected to the upper part of the product, and the shape and specification of the feeding screw groove match the upper part of the product, so that the products are evenly arranged side by side on the loading screw, preventing the products from stacking, facilitating the grasping unit to grab the materials, and improving the loading efficiency.

[0042] During loading, the junction box is put on the loading screw, so that the products are arranged in the feeding screw groove and are automatically arranged in order according to the position of the feeding screw groove; the servo translation mechanism drives the translation frame to a suitable position so that the friction drive wheel aligns with a loading screw; the pressing cylinder drives the lifting seat to descend, so that the friction drive wheel is in contact with the friction transmission wheel on the loading screw; the drive motor drives the friction drive wheel to rotate, and the friction drive wheel drives the friction transmission wheel to rotate through friction, so that the loading screw rotates axially on the screw seat; when the loading screw rotates, the feeding screw groove drives the products to move forward, so that the product arranged in the first place falls on the receiving conveyor belt on the receiving unit; the 4-axis manipulator grabs the product according to the visual inspection result and adjusts the shape of the product; then the product is placed on the transfer platform and flows into the next station; after the product materials on one loading screw are used up, the pressing cylinder rises and the servo translation mechanism moves, so that the friction drive wheel aligns with the next loading screw. If all the products on one loading trolley are loaded, the trolley is replaced.

[0043] The beneficial effects of the disordered automatic feeding mechanism for products with cable materials in the present invention are as follows: it can automatically load and unload products, which not only improves the feeding accuracy, but also greatly improves the production capacity. Moreover, it can automatically adjust the shape of the products, facilitating subsequent operations.

[0044] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
