Description

Technical Field

[0001] The invention relates to the technical field of wire cutting machines, in particular to an automatic wire cutting machine for fan electric wires. Background Art

[0002] A fan is a device that generates wind by driving the blades to rotate through a motor, accelerating the flow of air. It is widely used in many fields such as life and industry, especially in hot summer, when the fan can cool down the air. The fan wire is a very important component of the fan. It mainly connects the power supply and the fan motor so that the fan can operate normally. Existing fan manufacturers will manufacture fans with wires of different lengths according to people's different needs. Traditional wires are usually cut manually with a cutter. With the continuous development of technology, existing fan manufacturers generally use automatic wire cutting machines to quickly manufacture wires of different lengths.

[0003] The existing automatic wire cutting machine generally includes a feeding system, a wire cutting system, a terminal supply system, a wiring system, a control system, etc. The specific principle is: first, the wire is guided by the guide wheel from the feed tray of the feeding system to the feeding channel controlled by the feeding motor, and fed at a set speed. During the feeding process, the length measuring device of the wire cutting system starts to work. When the wire length reaches the preset wire cutting length, the wire cutting tool quickly cuts the wire under the action of the driving mechanism. At the same time, the terminal supply system transports the terminal from the tray along the conveying track to the wiring position, and ensures its accurate position through the positioning device. The cut wire reaches the wiring position under the action of the machine's transmission device and aligns with the terminal. Finally, the crimping machine of the wiring system crimps the wire and the terminal according to the set pressure and time to make them firmly connected together. After the connection is completed, the finished wire (with terminal) is output, and the machine starts the next round of wire cutting and wiring cycle. For example, the prior art publication number CN112059069A is an automatic cutting machine for wires of different lengths. In this invention, the length of the wire fed in after the upper roller rotates two weeks is equal to the length of the measuring platform. When the feeding speed is controlled, the length of the wire on the measuring platform when the upper roller rotates one circle can be obtained through the CCD camera, and the length of the wire fed in after the upper roller rotates one circle can be deduced in turn. The length of the wire fed in after the upper roller rotates one circle can be obtained by obtaining the number of rotations of the upper roller through the output shaft speed sensor.

[0004] However, the above-mentioned prior art still has the following problems when in use: when the existing automatic wire cutting machine is unloading, when the cut wires fall into the unloading trough, multiple wires will be piled up in the unloading trough in a disorderly manner, and the staff are required to manually organize the wires. At the same time, the wires need to be manually picked up for transportation, which is time-consuming and labor-intensive to use, resulting in low production efficiency of fan wires. Based on this, the present invention provides an automatic fan wire cutting machine that is easy to organize fan wires and has high processing efficiency. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic wire cutting machine for fan wires, which drives two rotating rods connected by a gear transmission assembly to rotate through a servo motor, thereby driving a sorting plate to push the fan wires to a feeding port, and at the same time, a top plate moves downward to cooperate with the two sorting plates to increase the falling speed of the fan wires, thereby improving the cutting efficiency of the fan wires to solve the problems arising from the above-mentioned background technology.

[0010] In a preferred embodiment, two electric push rods are fixed and penetrated through the top of the mounting plate, and the bottom ends of the piston rods of the two electric push rods penetrate the mounting plate and are fixed to the top of the top plate.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Refer to the instruction manual Figure 1-10The present invention provides an automatic wire cutting machine for fan wires, comprising a processing machine 1, on which a detachable feeding mechanism 2, a wire cutting terminal mechanism 3 and a linear module 4 are fixedly provided. Specifically, the linear module 4 has a model of tjkk8620p. The linear module 4 is a key transmission component in an automation device, which can convert the rotational motion of a motor into a linear motion for conveying fan wires for unloading. A wire feeding mechanism 5 is fixedly provided on the linear module 4, and a semicircular groove 6 is provided on the top of the processing machine 1.

[0034] Specifically, the wire cutting and terminal connection mechanism 3 usually adopts a knife cutting method, and the cutter is driven by a motor or a cylinder. When the wire is delivered to the set length position, the driving device will drive the cutter to move quickly to cut the wire. In the process of cold crimping the terminal, there is a special crimping die, and the shape of the die matches the shape of the terminal. When the wire is inserted into the terminal, the crimping die tightly wraps the metal part of the terminal on the wire under pressure. The wire feeding mechanism 5 is an electric clamp used to clamp one end of the fan wire and move it. The above technologies are all existing common technologies and will not be further described here.

[0035] During use, one end of the fan wire placed on the loading component is first cut and connected to the terminal by the wire cutting and terminal connecting mechanism 3, and then fixed by the wire feeding mechanism 5. Driven by the linear module 4, the fan wire is moved to the right side of the processing machine 1, and then the fan wire is cut off by the wire cutting and terminal connecting mechanism 3. At the same time, the wire feeding mechanism 5 is released to place the fan wire in the semicircular groove 6, and the automatic cutting and terminal connecting work of the fan wire is completed. The cut fan wire moves to the bottom of the semicircular groove 6 to facilitate unloading.

[0036] Refer to the instruction manual Figure 1-10 A material discharge mechanism 7 is provided inside the semicircular groove 6, and the material discharge mechanism 7 includes a collection frame 701 connected to the bottom of the processing machine 1. A material discharge port 702 is provided at the bottom of the semicircular groove 6, and the material discharge port 702 is communicated with the inside of the collection frame 701. Two sorting plates 703 are provided inside the semicircular groove 6, and the two sorting plates 703 are connected to the same mounting plate 704 on the side away from the wire cutting terminal mechanism 3, and a top plate 705 is provided at the bottom of the mounting plate 704.

[0037] The mounting plate 704 is also provided with a driving assembly 8 for driving the two sorting plates 703 to rotate. The driving assembly 8 includes two rotating rods 801. The two rotating rods 801 are both rotatably connected to the side of the mounting plate 704 close to the wire feeding mechanism 5. The two rotating rods 801 are respectively fixed to the two sorting plates 703, and the two rotating rods 801 are connected by a gear transmission assembly 802. The gear transmission assembly 802 is located between the mounting plate 704 and the sorting plate 703, and is used to rotate the two sorting plates 703 simultaneously.

[0038] In addition, a detachable servo motor 803 is fixedly provided on the side of the mounting plate 704 away from the rotating rod 801. Specifically, the model of the servo motor 803 is R88M-1M75030H-BS2. The servo motor 803 is a rotary actuator or a linear actuator, which allows precise control of the angular velocity or linear position, speed and acceleration. Therefore, the two sorting plates 703 can be driven to rotate stably by the servo motor 803. One end of the output shaft of the servo motor 803 passes through the mounting plate 704 and is detachably connected to one of the rotating rods 801. The servo motor 803 is used as a power source, which can save the time of manual operation and thereby improve the feeding efficiency of the fan wires.

[0039] Moreover, two electric push rods 9 are fixed and passed through the top of the mounting plate 704. Specifically, the model of the electric push rod 9 is jc35b8. The electric push rod 9 is a device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The bottom ends of the piston rods of the two electric push rods 9 pass through the mounting plate 704 and are fixed to the top of the top plate 705, so as to adjust the height of the top plate 705.

[0040] Next, fixed plates 12 are fixed on the top of the front and rear sides of the collection frame 701, and at least one spring pin 13 is fixed through the two fixed plates 12. The bottom of the processing machine 1 is provided with slots 14 with the same number as the multiple spring pins 13. The spring pins 13 are plugged into the slots 14 to facilitate the staff to connect the fixed plates 12 and the processing machine 1.

[0041] Two positioning blocks 15 are fixed on the top of the two fixing plates 12, and the bottom of the processing machine 1 is provided with positioning grooves 16 with the same number as the positioning blocks 15. The positioning blocks 15 are arranged in the positioning grooves 16 to improve the firmness of the connection between the fixing plates 12 and the processing machine 1.

[0042] The collection frame 701 has an opening 17 at the front end, a door panel 18 is hinged in the opening 17, and the door panel 18 is locked to the collection frame 701 via a key lock. The use of the key lock can improve the firmness between the door panel 18 and the collection frame 701.

[0043] A servo motor 803 is used to drive two rotating rods 801 connected by a gear transmission assembly 802 to rotate together. The connecting plates on the two rotating rods 801 drive the sorting plate 703 to rotate in the semicircular groove 6, automatically pushing the fan wires in the semicircular groove 6 to the unloading port 702. At the same time, the two electric push rods 9 are extended to drive the top plate 705 to move downward. In combination with the two sorting plates 703, the speed at which the fan wires fall can be increased, thereby improving the cutting efficiency of the fan wires. When not in use, the staff pulls the spring latch 13 out of the slot 14 to separate the fixing plate 12 from the processing machine 1. The collection frame 701 can be used as a tool for transporting the fan wires, and the door panel 18 can also be opened to take the wires.

[0044] Refer to the instruction manual Figure 1-4 The feeding mechanism 2 includes a mounting frame 201 detachably connected to one side of the processing machine 1, and a plurality of supporting material plates 202 are rotatably connected to the top of the mounting frame 201. A vertical rod 203 is fixed at the center of the top of each supporting material plate 202 to prevent the stacked plurality of fan wire coils from falling off.

[0045] In addition, a detachable limit frame 10 is fixedly provided on one side of the processing machine 1. The limit frame 10 is located above a plurality of vertical rods 203, and the limit frame 10 is detachably connected with wire management rollers 11 having the same number as the vertical rods 203, which are used to guide the fan wires so that the fan wires can be stably transported to the processing machine body 1 for cutting and connecting terminals.

[0046] By placing multiple rotatable supporting material plates 202 on the mounting frame 201 and stacking multiple fan wire coils on the round rod, the time for workers to move and load materials can be saved. At the same time, the vertical rods 203 can limit the fan wire coils on the supporting material plates 202 to prevent the stacked fan wire coils from falling.

[0047] In actual use, a control box can be installed on the processing table 1 to control the wire cutting and terminal connection mechanism 3, linear module 4, wire feeding mechanism 5, electric push rod 9, and servo motor 803 in the present invention, and there is a battery inside the control box to provide electrical energy. The above technologies are all existing commonly used technologies and will not be further elaborated here.

[0048] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
