Description

Technical Field

[0001] The present invention relates to the technical field of electronic component production, and specifically relates to a capacitor pin positioning and cutting mechanism. Background Art

[0002] As a basic component in an electronic circuit, the pins of a capacitor need to be cut before soldering to meet the installation dimension requirements. Existing cutting methods mostly use manual operation or simple fixture positioning, and have the following defects: 1. Inconsistent cutting lengths: Manual visual positioning is prone to deviation, resulting in uneven pin lengths, which affects the subsequent automatic soldering efficiency; 2. Poor fixing stability: The cylindrical body of the capacitor is prone to rolling during cutting, and the planar clamping structure of the existing fixture is difficult to effectively fix; 3. Inconvenient waste treatment: The waste pins after cutting are prone to accumulate on the operation table, and it is necessary to frequently stop the machine for cleaning, reducing production efficiency; 4. Insufficient adaptability: A single fixture is difficult to adapt to capacitors of different diameters, and the process of replacing the fixture is cumbersome.

[0003] In view of the above problems, although there are some automatic cutting devices in the prior art, their structures are complex, the costs are high, and they lack an integrated design of high-precision positioning and waste collection.

[0004] Therefore, there is an urgent need for a pin cutting mechanism with a compact structure, precise positioning and adaptable to multiple specifications of capacitors. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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.

[0019] Please refer to Figures 1-6 As shown in the figure, the present invention provides a technical solution: a capacitor pin positioning and cutting mechanism, including: a fixed seat 1, on the upper part of which there are a lifting slide rail 2 and a lifting slide table 3 that can move up and down along the lifting slide rail 2; the lifting slide table 3 is driven by a cylinder or a motor to achieve precise lifting.

[0020] A cutting blade plate 4, which is connected to the lifting slide table 3, the cutting blade plate 4 is connected with a cutting blade mounting block 5, the cutting blade mounting block 5 is provided with a pin cutting blade 6, the pin cutting blade 6 is made of high-hardness alloy material, the lifting slide table 3 drives the cutting blade plate 4 to move vertically, and synchronously drives the pin cutting blade 6 to move vertically to cut the pins, realizing one-time punching, the cut is smooth and burr-free, the cutting blade mounting block 5 and the cutting blade plate 4 are connected by bolts, and the cutting blade mounting block 5 is provided with a fine-tuning groove for adjusting the horizontal position of the pin cutting blade 6, allowing the horizontal position of the pin cutting blade 6 to be adjusted by bolts to adapt to different cutting requirements.

[0021] The cutting table 7 is arranged on the top of the fixed seat 1. The cutting table 7 is provided with a horizontal slide rail 8 and two sets of cross slide tables 9 that can move back and forth along the horizontal slide rail 8. The cross slide tables 9 are driven by cylinders or motors to achieve precise cross movement. Each set of cross slide tables 9 is equipped with a connecting block 10, and the connecting block 10 is connected with a positioning block 11 for aligning the capacitor. The positioning block 11 is connected to the connecting block 10 by bolts. By adjusting the bolts, the distance between the positioning block 11 and the fixed block 12 can be adjusted to adapt to capacitors with different pin lengths.

[0022] The fixed block 12 is arranged on the cutting table 7 and corresponds to the cutting position of the pin cutter 6. The fixed block 12 is provided with a V-shaped bayonet 13 for fixing the capacitor. The inclination angle of the V-shaped bayonet is 60° - 120°. The inner surface of the V-shaped bayonet is provided with anti-slip lines for stably clamping the cylindrical capacitor. The inclined surface clamping structure of the V-shaped bayonet 13 fits the shaft body of the capacitor, and the anti-slip lines are used to increase the friction force to prevent the capacitor from sliding or rotating during cutting. It should be noted that as long as the capacitor is not pushed horizontally, the V-shaped bayonet 13 can stably fix the capacitor.

[0023] The auxiliary block 14 is arranged on the cutting table 7 and cooperates with the fixed block 12 to support the capacitor pins to prevent the pins from bending during cutting. The cutting table 7 is provided with installation positions 16 for fixing the fixed block 12 and the auxiliary block 14. The fixed block 12 and the auxiliary block 14 adopt a modular design and can be quickly disassembled and assembled through the installation positions, which is convenient for replacing fixed blocks of different sizes to adapt to multi-specification capacitors. See Figure 2 As shown, induction sheets 17 are arranged on the left and right sides of the cutter plate 4, and sensors 18 that cooperate with the induction sheets 17 are arranged on the rear side of the connecting block 10. Through the design of the induction sheets 17 and the sensors 18, a non-contact detection system is formed to realize position detection and signal feedback, ensuring the accuracy of driving the two side positioning blocks 11 to move towards the middle by the cross slide table 9. In the middle of the top surface of the cutting table 7, there is a cutting waste outlet 15, and the cut pin waste directly falls into the collection container below through the outlet, avoiding waste accumulation.

[0024] The working principle of the capacitor pin positioning and cutting mechanism: See Figures 1-3As shown in the figure, the capacitor is placed into the V-shaped bayonet 13 on the top of the fixed block 12, and the pins are horizontally placed on the top surface of the auxiliary block 14. The cross-slide 9 drives the connecting blocks 10 on both sides to move horizontally, and synchronously drives the positioning block 11 to move towards the middle. The positioning block 11 pushes the rear end of the capacitor to be flush with the vertical surface of the fixed block 12. Since the sensor 18 is configured on the connecting block 10, through the cooperation of the sensor 18 and the induction sheet 17, position detection is realized to ensure the accuracy of the cross-slide 9 driving the positioning blocks 11 on both sides to move towards the middle. After the positioning of the capacitor is completed, the lifting slide 3 drives the cutter plate 4 to move downward, and the cutter plate 4 synchronously drives the pin cutter 6 to move downward. The pin cutter 6 cuts the pins in the vertical direction. After the cutting is completed, the cross-slide 9 drives the positioning block 11 to return to the original position, the lifting slide 3 moves upward to reset, and the cut capacitor is taken out to enter the next round of pin cutting process.

[0025] Please read Figures 7-8 As shown in the figure, there is a spacing 131 between the positioning block 11 and the bayonet 13. The spacing 131 is used to adjust the length distance of the capacitor. The purpose is also to make the capacitor fit the surface of the positioning block 11. In this way, the capacitor 132 can be arranged in the middle of the bayonet 13. In this way, a part of the pin 133 of the capacitor 132 is also in the groove of the bayonet 13, and the other part is arranged on the surface of the auxiliary block 14. In this way, the capacitor can be placed stably. Then, when the pin cutter 6 moves downward, the pin cutter 6 is in contact with the two surfaces of the bayonet 13, and a scissor function is formed, so as to cut the pin 133 to obtain the desired pin length, which is convenient for further processing.

[0026] It should be noted that there is a cavity on one side of the bayonet 13. This cavity is a receiving chamber for the cutter 6 during cutting. It can be attached Figure 5 It can be seen.
