Description

Technical Field

[0001] This utility model relates to the field of cutting structure technology, specifically a needle insertion machine thread feeding and cutting structure. Background Technology

[0002] A pin insertion machine, also known as an automatic pin insertion machine or PIN insertion machine, is an automated device specifically designed for inserting pins into electronic components. It primarily serves the pin insertion needs of various coil frames for electronic transformers, relays, fan motors, and other components. The wire feeding and cutting structure is a key functional module within the pin insertion machine, responsible for automatically feeding, precisely positioning, and cutting the wire to specifications. Its design aims to ensure the efficiency and accuracy of wire handling during the pin insertion process. The wire feeding and cutting structure is mainly used in the electronics manufacturing industry, specifically in connector production. It cuts the copper wire for pin insertion into specified lengths. This mechanism, used on the pin insertion machine, is responsible for feeding the coiled wire to the pin fingers, straightening it, and cutting it into segments to form pins.

[0003] Currently, there are similar products on the market. Their traditional wire feeding method is generally pushed by a cylinder, and the length is fixed and not easy to adjust. Moreover, the wire is usually clamped and inserted into the product first, and then cut. In this way, for the same product, if there are multiple needles with different lengths, it is impossible to meet the requirements by inserting the needles in one go. It is necessary to insert the needles in two or more times to complete one product. The working efficiency of the device is low, which reduces the practical performance of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a needle insertion machine with a wire feeding and cutting structure. By using this device, the problems of the traditional wire feeding method mentioned above are solved. The traditional method usually uses a cylinder to push the wire, which has a fixed length and is not easy to adjust. Moreover, the wire is usually clamped and inserted into the product first, and then cut. In this way, for the same product, if there are multiple needles with different lengths, it is impossible to insert the needles in one go. It is necessary to insert the needles in two or more times to complete one product. This results in low working efficiency and reduced practical performance of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a needle insertion machine wire feeding and cutting structure, including a base plate, a main upright plate fixedly connected to the top of the base plate, a winding roller mechanism provided on one side of the top of the main upright plate, a wire body evenly wound around the outer circumference of the winding roller mechanism, a wire feeding mechanism provided on one side of the main upright plate, the wire feeding mechanism being used to transmit the wire body, an upright plate support fixedly connected between the base plate and the winding roller mechanism, two sets of upright plate supports being provided, the two sets of upright plate supports being used to improve the connection stability between the base plate and the main upright plate, a servo module provided on one side of the main upright plate, and a mounting box provided on one side of the servo module, the servo module being used to drive the mounting box to move up and down.

[0006] Preferably, the mounting box is provided with a clamping assembly, and two sets of parallel finger cylinders are fixedly connected inside the mounting box.

[0007] The above-mentioned mechanism is designed so that the clamping block is moved by a cylinder.

[0008] Preferably, a left finger clamp and a right finger clamp are slidably connected inside the mounting box. The left finger clamp and the right finger clamp match each other. The cable body is disposed between the left finger clamp and the right finger clamp. The left finger clamp and the right finger clamp are used to clamp and fix the cable body.

[0009] The above-mentioned mechanism stabilizes the wire by using left and right clamps, preventing it from shifting during wire cutting.

[0010] Preferably, the left finger clamp and the right finger clamp are fixedly connected to the output ends of the two sets of parallel finger cylinders, respectively.

[0011] Preferably, a cutting cylinder is fixedly connected to the rear side of the main upright plate, and a cutting blade is slidably connected to the top surface of the bottom plate. A cylinder connecting rod is provided on the rear side of the cutting blade, and the cutting blade is fixedly connected to the output end of the cutting cylinder through the cylinder connecting rod.

[0012] Using the above-mentioned mechanism, the wire is cut by the relative movement of the upper and lower blades.

[0013] Preferably, a lower blade of a cutting tool is fixedly connected to one side of the base plate, and the upper blade of the cutting tool matches the lower blade of the cutting tool. Both the upper blade and the lower blade of the cutting tool have thread holes on one side.

[0014] With the above-mentioned design, the wire needs to pass through the wire hole to pass through the upper and lower blades.

[0015] Preferably, one end of the wire body passes through the mounting box and extends to the outside of the base plate, and the wire body passes through two sets of wire holes.

[0016] With the above-mentioned mechanism, the two sets of threading holes are the same size, and when the device is not in use, the threading holes of the upper cutter and the lower cutter are aligned and coincide.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The present invention proposes a needle insertion machine wire feeding and cutting structure, which transmits the wire through the wire feeding mechanism of the device and fixes the wire with the clamp of the device. It usually uses high-speed steel or carbide blades, which are divided into fixed blades and movable blades. The wire is cut by shearing or punching. The shape of the blade is designed according to the specifications of the wire to ensure that the cut is flat and burr-free. The blade is driven by a cylinder to achieve rapid cutting. The cylinder drive structure is simple and has a fast response, while the motor drive makes it easier to accurately control the cutting force and position.

[0019] 2. This patent uses a servo motor to drive a parallel finger gripper block, which clamps the wire and feeds it. The distance the servo motor moves is controlled by the program, thereby controlling the length of the wire fed. The wire is fed a shorter distance when inserting a short needle and a longer distance when inserting a long needle. After being cut by a cutting tool, the wire is then picked up by a needle-inserting finger cylinder and inserted into different positions on the product. This solves the problem that if there are two or more needles of different lengths on the same product, the product needs to be placed on the workstation twice or multiple times to complete the needle insertion action.

[0030] Combination Figures 1-7 A needle insertion machine wire feeding and cutting structure includes a base plate 1, a main upright plate 2 fixedly connected to the top of the base plate 1, a winding roller mechanism 11 provided on one side of the top of the main upright plate 2, a wire body 12 evenly wound around the outer periphery of the winding roller mechanism 11, a wire feeding mechanism 13 provided on one side of the main upright plate 2, the wire feeding mechanism 13 is used to transmit the wire body 12, an upright plate support 3 is fixedly connected between the base plate 1 and the winding roller mechanism 11, two sets of upright plate supports 3 are provided, the two sets of upright plate supports 3 are used to improve the connection stability between the base plate 1 and the main upright plate 2, a servo module 4 is provided on one side of the main upright plate 2, and a mounting box 41 is provided on one side of the servo module 4, the servo module 4 is used to drive the mounting box 41 to move up and down.

[0031] The present invention will be further described below with reference to the embodiments. Example

[0032] The mounting box 41 is equipped with a clamping component, and two sets of parallel finger cylinders 5 are fixedly connected inside the mounting box 41.

[0033] The mounting box 41 has a sliding connection between a left finger clamp 6 and a right finger clamp 61. The left finger clamp 6 and the right finger clamp 61 match each other. The cable body 12 is located between the left finger clamp 6 and the right finger clamp 61. The left finger clamp 6 and the right finger clamp 61 are used to clamp and fix the cable body 12.

[0034] The left finger clamp 6 and the right finger clamp 61 are fixedly connected to the output ends of the two sets of parallel finger cylinders 5, respectively.

[0035] A cutting cylinder 7 is fixedly connected to the rear side of the main upright plate 2, and a cutting blade 9 is slidably connected to the top surface of the bottom plate 1. A cylinder connecting rod 8 is provided on the rear side of the cutting blade 9, and the cutting blade 9 is fixedly connected to the output end of the cutting cylinder 7 through the cylinder connecting rod 8.

[0036] A lower blade 10 of a cutting tool is fixedly connected to one side of the base plate 1. The upper blade 9 of the cutting tool and the lower blade 10 of the cutting tool are matched with each other. Both the upper blade 9 and the lower blade 10 of the cutting tool have thread holes on one side.

[0037] One end of the wire body 12 passes through the mounting box 41 and extends to the outside of the base plate 1, and the wire body 12 passes through two sets of wire holes.

[0038] In summary: Base plate 1 supports the entire structure. There are four column mounting holes on both sides of base plate 1 for easy connection and installation with other components. The center hole is a square hole, and one side of the square hole has a slot connecting to a small square hole. The upper blade 9 of the cutting tool is installed above the small square hole, and the lower blade 10 of the cutting tool is installed below the square hole. A main upright plate 2 is installed on one side of base plate 1, and the main upright plate 2 is supported by two support columns. A winding roller mechanism 11 is installed at the upper end of the main upright plate 2. The winding roller mechanism 11 is used to wind and store the wire body 12. One end of the wire body 12 extends to the wire feeding mechanism 13. A stepper motor is installed on the rear side of the wire feeding mechanism 13 to provide power for wire feeding. It can precisely control the wire feeding speed and length. The wire feeding roller assembly consists of a driving wheel and a driven wheel. It clamps the wire through friction to ensure that it does not slip during the feeding process. The roller surface may be designed with anti-slip texture or elastic material to enhance the clamping force. A servo module 4 is installed on one side of the main upright plate 2. The servo module 4 is used to lift and lower the mounting box 41 and the internal clamps. The left finger clamp 6 and the right finger clamp 61 in the mounting box 41 are used together to clamp the wire body 12 through two sets of parallel fingers. Cylinder 5 controls the extension and retraction of the left finger clamp 6 and the right finger clamp 61 respectively. When the left finger clamp 6 and the right finger clamp 61 open, the concave and convex parts separate, and the wire body 12 in the middle can move freely. When the left finger clamp 6 and the right finger clamp 61 close, they can clamp and fix the wire body 12. A cutting cylinder 7 is installed on the rear side of the main upright plate 2. The blade 9 on the cutting tool is connected to the output end of the cutting cylinder 7 through the cylinder connecting rod 8. The cutting cylinder 7 is used to push the blade 9 on the cutting tool to move. A wire hole is provided on one side of the blade 9 on the cutting tool, and the wire body 12 passes through... The upper blade 9 of the cutting tool is placed in the square hole of the base plate 1 and moves back and forth in the hole. The lower blade 10 of the cutting tool is fixedly installed on one side of the base plate 1 and also has a thread hole. The thread holes on the upper blade 9 and the lower blade 10 of the cutting tool match each other. The wire body 12 also passes through the thread hole in the lower blade 10 of the cutting tool. When the cutting cylinder 7 pushes the upper blade 9 of the cutting tool to move, the upper blade 9 and the lower blade 10 of the cutting tool move relative to each other, so that the wire body 12 is cut.Two sets of parallel finger cylinders 5 drive the left finger clamp 6 and right finger clamp 61 to move closer together, clamping and fixing the wire body 12. The servo module 4 in the device is a lifting mechanism. When the servo module 4 moves downward, the clamp in the mounting box 41 clamps the wire body 12, pulling it downward. The length of the movement of the mounting box 41 is determined by the position of the servo movement. By programming, the position of the servo movement can be controlled arbitrarily, thus controlling the length of the wire body 12. When the servo module 4 returns to the zero point, the left finger clamp 6 and right finger clamp 6... Block 61 releases the wire body 12, which remains stationary. The servo's movement distance can be controlled via programming, thereby controlling the wire feeding length. The length can be changed in real-time according to product requirements, allowing for the continuous feeding of wire bodies 12 of varying lengths. After cutting, a needle is formed, which is then clamped by a needle inserter and inserted into the product. This saves time, improves efficiency, and eliminates the hassle of frequent fixture changes. In conjunction with the entire machine, once the needle inserter has removed the needle, the wire feeding mechanism 13 begins feeding the wire, waiting for the needle inserter to clamp and cut the wire again. This virtually eliminates waiting time for wire feeding, significantly increasing production capacity and improving the machine's efficiency.
