Description

Technical Field

[0001] This utility model relates to an automatic pin-cutting device for electronic components on a circuit board, belonging to the field of circuit board processing technology. Background Technology

[0002] In the manufacturing process of electronic devices, the circuit board is a core component, and its assembly quality directly affects the performance and reliability of the product. After the smoke sensor is installed on the circuit board, the excess pins need to be trimmed to ensure the cleanliness of the circuit board and the stability of the electrical connection.

[0003] Currently, the pin removal process on circuit boards typically involves hand-held pliers to cut the electronic component pins. However, this method is inefficient, and due to variations in manual operation, it is difficult to ensure consistent pin lengths, often resulting in pins being cut too short or too long. Furthermore, the waste pins cannot be collected quickly, leading to a messy workbench. To address these issues, we provide an automatic pin removal device for circuit board electronic components.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4In this utility model, an automatic pin-removing device for electronic components on a circuit board includes a chassis 1. Two support plates 2 are connected to the outer surface of the chassis 1. An electric slide 3 is mounted on the upper surface of both support plates 2. A lifting device 4 is provided on one side of the electric slide 3. The lifting device 4 includes a motor, a lead screw and nut mechanism, and a guide rail and slider mechanism. The motor serves as the power source, providing driving force for the lifting motion. The lead screw and nut mechanism converts the rotational motion of the motor into linear motion, realizing the lifting function. An electric shear 5 is installed at the output end of the lifting device 4. The electric shear 5 generally consists of a motor, a transmission mechanism, and a blade assembly. It operates by the heat generated by the motor, enabling... The transmission mechanism transmits power to the blade, which opens and closes under the drive of the power. When the blade closes, it applies a shearing force to the pins of the electronic components, thereby cutting off the pins. This is the existing technology. A collection box 6 is installed on one side of the chassis 1. A chip suction component 7 is installed on the upper surface of the collection box 6. Two slides 11 are installed on the upper surface of the chassis 1. Electric sliders 12 are slidably connected to the outer surfaces of the two slides 11. The principle of the electric sliders 12 sliding above the slides 11 is that the electric sliders 12 have a built-in motor and a matching roller. The motor drives the roller to slide on the slides 11, which can also ensure stability and accuracy during the movement.

[0020] The upper surfaces of the two electric sliders 12 are each connected to a fixed platform 13. The upper surfaces of the two fixed platforms 13 are each hinged with an elastic positioning element 14 via a damping hinge. The damping hinge typically consists of a fixed part, a movable part, and a damping mechanism. The fixed part is used to mount on one component, while the movable part is connected to another component. The rotational connection is achieved through a central pivot. The damping mechanism generally uses hydraulic or pneumatic principles, but some also utilize friction principles to achieve a damping effect. It provides a force that resists rotation, making the rotation process smoother and slower. The elastic positioning element 14 is rotated above the fixed platform 13 via the damping hinge, allowing it to press against the circuit board. The elasticity of the elastic positioning element 14 is used to fix and position the circuit board, ensuring stability during pin trimming. A controller 15 is installed on one side of the chassis 1, allowing the device to be controlled.

[0021] Preferably, the electric slide block 3 includes a slide block 301, the upper surfaces of the two support plates 2 are connected to the bottom surface of the slide block 301, a forward and reverse motor 302 is installed on the inner wall of the slide block 301, a transmission screw 305 is installed at the output end of the forward and reverse motor 302, a transmission block 303 is threadedly connected to the outer surface of the transmission screw 305, a strip hole 306 is opened on one side of the slide block 301, one end of the transmission block 303 passes through the strip hole 306 and is connected to one side of the lifting device 4, and the outer surface of the transmission block 303 is connected to the slide block 301. The inner wall of the movable seat 301 is slidably connected, and a bearing ring 304 is embedded in the inner wall of the sliding seat 301. One end of the transmission screw 305 is connected to the inner ring of the bearing ring 304. The rotation of the transmission screw 305 is driven by the forward and reverse motor 302, which will be threadedly connected to the transmission block 303 and will cause the transmission block 303 to move inside the sliding seat 301. At the same time, it will also drive the lifting device 4 and the electric scissors 5 to move in the horizontal direction, so that the electric scissors 5 can reach the position of different pins on the circuit board to perform cutting work.

[0022] Preferably, the chip suction assembly 7 includes a chip suction hood 701, a chip suction fan 702 installed on the inner wall of the chip suction hood 701, the bottom surface of the chip suction hood 701 connected to the upper surface of the collection box 6, a chip suction pipe 703 connected to the top of the chip suction hood 701, a corrugated hose 704 connected to one end of the chip suction pipe 703, and one end of the corrugated hose 704 connected to the outer surface of the electric scissors 5. The chip suction fan 702 generates suction under the control of the controller 15, and can suck in the chips generated when cutting the pins through the chip suction pipe 703 and the corrugated hose 704, and discharge them into the collection frame 8 inside the collection box 6, thereby achieving the effect of collecting the chips after cutting the pins.

[0023] Preferably, a collection frame 8 is placed on the inner bottom wall of the collection box 6, and a protective door 9 is hinged to one side of the collection box 6 by a pin. Two exhaust mesh plates 10 are inlaid on the outer surface of the collection box 6. Opening the protective door 9 makes it easy to remove the collection frame 8 for cleaning. The exhaust mesh plates 10 allow the gas emitted by the chip suction fan 702 to be discharged through the exhaust mesh plates 10 when it is working, ensuring air circulation in the collection box 6 and preventing debris from escaping from the exhaust mesh plates 10.

[0024] The working principle of this utility model is as follows:

[0025] In use, the circuit board is first placed on the fixed platform 13. Then, the elastic positioning member 14 is rotated by the damping hinge to press the elastic positioning member 14 onto the circuit board. The elasticity of the elastic positioning member 14 is used to fix and position the circuit board. Next, the electric slider 12 is controlled by the controller 15 to adjust the position of the fixed platform 13. Then, the electric slide 3 is started to drive the lifting device 4 and the electric scissors 5 to move flexibly left and right, which facilitates the adjustment of the cutting position of the electric scissors 5. Then, the lifting device 4 drives the electric scissors 5 to descend to a suitable height, so that it is close to the electronic component pins on the circuit board and cuts them off. The chip suction component 7 works to suck up the cut pin waste and discharge it into the collection frame 8 inside the collection box 6 for easy subsequent cleaning.
