[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model. Example 1

[0020] Reference Figure 1-3The diagram illustrates the tube threading and feeding mechanism in a fiber tube threading device, which enables automatic threading and serial connection of fiber tubes on a telescopic belt. It includes a feeding unit 100, a pushing unit 200, a clamping unit 300, and a positioning unit 400. The feeding unit 100 stores the pre-cut tubes S in a hopper, which is then stacked downwards by gravity. The pushing unit 200 is located below the feeding unit 100 and pushes the tubes S out of the feeding unit 100. The clamping unit 300 is located above the pushing unit 200 and clamps the tubes S pushed out by the pushing unit 200 to the positioning unit 400. The positioning unit 400 then positions the clamped tubes S at their current position, preparing for the next threading process.

[0021] Specifically, the feeding unit 100 also includes a feeding bin 101 and a discharging bin 102. The feeding bin 101 is located above the discharging bin 102 and the inclined surfaces of the two intersect. The pipe S can roll from the feeding bin 101 into the discharging bin 102 and continue to roll downwards. It should be noted that the cut pipes S need to be arranged and stacked manually in advance. When the pipes S in the bin are used up, they are stacked manually again, and this cycle is repeated.

[0022] Furthermore, the pushing unit 200 is located below the unloading bin 102 and is used to push the tube S in the unloading bin 102 upward. In this embodiment, the pushing unit 200 also includes a pushing plate 201 and a pushing cylinder 202. The pushing cylinder 202 is used to drive the pushing plate 201 to move up and down. The pushing plate 201 is located below the tube S. When the pushing plate 201 moves upward, it pushes the tube S upward until it is pushed out of the unloading bin 102 to the clamping position. After the clamping unit 300 clamps the tube S, the pushing plate 201 moves downward. When it moves to a plane lower than the unloading bin 102, the tube S slides down to the top of the pushing plate 201 due to gravity. This cycle is repeated to push the tube S.

[0023] Furthermore, the clamping unit 300 is used to clamp the tube S pushed out by the pushing unit 200 to the next work station, that is, the positioning work station. In this embodiment, the clamping unit 300 includes a gripper 301, an opening and closing cylinder 302, a lifting cylinder 303 and a telescopic cylinder 304, wherein the gripper 301 is located below the opening and closing cylinder 302, the opening and closing cylinder 302 is located below the lifting cylinder 303, and the lifting cylinder 303 is located on one side of the telescopic cylinder 304.

[0024] More specifically, the gripper 301 is used to clamp and release the tube S. The opening and closing cylinder 302 is located above the gripper 301 and provides the driving force for the gripper 301 to open and close. A cylinder is a cylindrical metal component that guides the piston to perform linear reciprocating motion inside the cylinder. Air in the engine cylinder converts thermal energy into mechanical energy through expansion; gas in the compressor cylinder is compressed by the piston to increase its pressure. Cylinders can be of the types that perform reciprocating linear motion or reciprocating oscillation. Controlled by a control signal, it is a pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission. The cylinder here is a very mature existing technology, and those skilled in the art can implement it by referring to existing technology, so it will not be described in detail.

[0025] Similarly, the lifting cylinder 303 and the telescopic cylinder 304 are the driving forces that control the gripper 301 to perform lifting and horizontal telescopic movements, respectively, so as to realize the free movement of the gripper 301 in space.

[0026] In this embodiment, the clamping unit 300 also includes a bracket 305. A telescopic cylinder 304 is fixedly mounted on the bracket 305. The bracket 305 is mounted on both ends of the unloading bin 102 via support plates at both ends. The gripper 301, the opening and closing cylinder 302, and the lifting cylinder 303 are mounted on one side of the telescopic rod of the telescopic cylinder 304. When the telescopic rod extends and retracts, it drives the gripper 301, the opening and closing cylinder 302, and the lifting cylinder 303 to extend and retract. The lifting cylinder 303 is directly connected to the telescopic rod. The opening and closing cylinder 302 is located below the lifting cylinder 303, and the gripper 301 is located below the opening and closing cylinder 302, thereby achieving the support and fixation of the clamping unit 300.

[0027] Furthermore, the positioning unit 400 is used to position the tube S held by the clamping unit 300. When the clamping unit 300 clamps the tube S to the position of the positioning unit 400, the positioning unit 400 positions the tube S. Specifically, in this embodiment, the positioning unit 400 includes a positioning claw 401 and a driving cylinder 402; wherein the positioning claw 401 is used to clamp the positioning tube S, and the driving cylinder 402 is used to drive the opening and closing of the positioning claw 401. The positioning unit 400 positions the tube S by the positioning claw 401, that is, the positioning claw 401 clamps the tube S in a fixed position to achieve positioning.

[0028] This embodiment also provides a clamping and receiving scheme, which includes a receiving unit 500, which is disposed on one side of the unloading bin 102. When the pusher plate 201 pushes the tube S downward, the tube S can roll into the receiving unit 500 under the guidance of the guide surface. Then, the clamping unit 300 clamps the tube S in the receiving unit 500 to the positioning unit 400, which can also realize the transfer of the tube S.

[0029] More specifically, the receiving unit 500 includes an inlet pipe groove 501 and an outlet pipe groove 502; wherein the inlet pipe groove 501 is located above the receiving unit 500, and the outlet pipe groove 502 is located on the outer side of the receiving unit 500, and the pipe S can fall from the inlet pipe groove 501 and be taken out from the outlet pipe groove 502. When tube S is pushed to a certain height by push plate 201, it falls into tube groove 501 due to the guiding effect of the guide surface. Then, a pusher is set behind tube groove 502 to support and push tube S out of tube groove 502. After being pushed out, tube S is clamped by gripper 301 to the positioning station. Compared with the method where tube S is directly pushed out by push plate 201 and then clamped by gripper 301 to the positioning station, this method is different because tube S may fall when push plate 201 is pushed out. When tube S falls out, push plate 201 needs to fall down again to push tube S out, which will affect the continuity of operation. Therefore, a receiving unit 500 is added to receive tubes. The tube groove height of receiving unit 500 can accommodate several vertically arranged tubes S. When tube S falls out when push plate 201 is pushed out, the receiving unit 500 already has tubes S for subsequent operations, so it will not affect the continuity of the production line, thus ensuring the continuity of the feeding action.

[0030] This embodiment also includes a workbench 600 for the fixed installation of various components, such as the feeding unit 100, the pushing unit 200, the clamping unit 300, and the positioning unit 400, all of which are mounted on the workbench 600. The workbench 600 also includes casters 601 and support feet 602 at the bottom. The casters 601 are used for the movement of the entire workbench 600, while the support feet 602 are used for fixing and stabilizing after movement to prevent the workbench 600 from moving due to shaking.

[0031] It should be noted that this embodiment should also include an electrical system for automating each component. In this embodiment, the number of fiber tube hoppers can be increased to 2-3. The electrical system consists of a human-machine interface, a PLC, safety protection devices, indicator lights, operation buttons, and the arrangement of electrical wiring. For the automatic control components, such as controlling the automatic operation of the cylinders, and automating the operation of the pushing unit 200, clamping unit 300, and positioning unit 400, this is achieved through a PLC, a programmable logic controller (PLC), a digital computing electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, controlling various types of mechanical equipment or production processes through digital or analog input / output. The above-mentioned technologies are mature existing technologies in the field of automation. Those skilled in the art can implement them without any innovative effort by referring to existing technologies. This embodiment aims to automate the structural design and connection of each component. The electrical system and its automation implementation are non-essential technical features and therefore will not be described in detail.

[0032] The working process of this embodiment: Refer to Figure 4 The illustration shows the actual application of the tube feeding mechanism proposed in this embodiment in automatic tube feeding operations. After the tube S is positioned by the positioning unit 400, the subsequent tube feeding operation is continued by the subsequent tube feeding equipment 700 after the feeding process is completed.

[0033] Specifically, after the equipment is powered on, a person manually clamps the elastic band into the fixture, presses the start switch, and the fiber tube is automatically pushed by the cylinder into the positioning fixture. When the incoming material detection switch has a signal, the shifting one-way robot moves the workpiece to the tube threading station. The tube threading robot moves, and the unloading and shifting robot clamps at the same time. After the process is completed, the shifting robot moves the fiber tube to the tail station and arranges them in sequence. After completion, a person manually removes the elastic band from the fixture and ties it in a knot, thus realizing automated tube threading operation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
