Description

Technical Field

[0001] This utility model relates to the field of circuit board contact cutting technology, specifically a circuit board component contact cutting machine. Background Technology

[0002] The contacts of circuit board components are usually called pins. They are the metal contact points or leads that make electrical connections between electronic components and printed circuit boards. Integrated circuit components are usually connected to the circuit board through pads. In order to achieve physical separation of components from the circuit board and facilitate independent testing or replacement of components, the contacts are usually cut.

[0003] In existing technology, circuit boards are manually loaded by hand, so that the soldered contacts come into contact with the cutting blade in the equipment to cut the contacts. However, when the cutting blade cuts the contacts, the cut contacts are prone to splattering. Manual loading can cause injury to the worker's hands. At the same time, the cutting blade will generate vibration when cutting the contacts, and the circuit board will shake when the worker holds it, which will affect the accuracy of the final circuit board cutting.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a circuit board component contact cutting machine. The machine comprises a main body 1 with a cavity on its upper interior. A cutting blade 2 is positioned in the center of the cavity. An automated feeding mechanism 4 is located in front of the cutting blade 2. This automated feeding mechanism 4 automatically feeds the circuit board to be cut, ensuring that the soldered contacts contact the cutting blade 2 for cutting. Automated feeding replaces traditional manual feeding, ensuring stability during contact cutting and preventing hand injuries to workers caused by manual feeding. Simultaneously, a cleaning mechanism 5 is located outside the cutting blade 2. This cleaning mechanism 5 blocks the waste generated by the cutting blade 2 during contact cutting, causing the waste to fall uniformly to the front of the upper cavity inside the main body 1, where it is then uniformly cleaned and collected.

[0026] like Figures 1-5 As shown, a device body 1 is provided. The lower end of the device body 1 is equipped with fixed casters. The fixed casters are locking casters. Movement and fixation are mainly achieved through the brake function. Before moving, the brake must be fully released to avoid the wheels getting stuck due to not unlocking, which facilitates the movement of the device body 1. When the device body 1 is moved to a suitable location, it is locked by lightly pressing the brake.

[0027] A cavity is provided on the upper side of the middle part of the device body 1. A cutting blade 2 is provided in the middle of the cavity. The bottom of the cutting blade 2 is fixedly connected to the output shaft of the motor. The motor is connected to a wire, which runs through the right side of the device body 1 and leads to the outside. Through the plug installed on the top, it can be connected to an external socket to make power, so that the cutting blade 2 can rotate. The cutting of the circuit board contacts can be performed inside the cavity.

[0028] Additionally, limit frames 3 are symmetrically arranged on the left and right sides of the outer side of the cutting blade 2. Limit slots 31 are opened inside the lower side of the limit frame 3. The horizontal position of the limit slots 31 is slightly higher than the top of the cutting blade 2. Furthermore, support frames 32 are fixedly installed on the front and rear sides of the lower end of the limit frame 3. A crossbar is installed through the lower end of the support frame 32. The left and right sides of the outer side of the crossbar are fixedly connected to the equipment body 1. The support frame 32 can firmly fix and support the limit frame 3.

[0029] Meanwhile, an automated feeding mechanism 4 is provided on the front side of the cutting blade 2. The automated feeding mechanism 4 is located on the front side of the middle of the limiting frame 3. The automated feeding mechanism 4 includes a fixed frame 41 located on the front side of the middle of the cutting blade 2. A limiting block 42 is fixedly installed at the middle of the rear end of the fixed frame 41. Rubber plates 44 are symmetrically arranged on the rear end of the limiting block 42. The output end of an electric push rod 43 (model HB-DJ801) is fixedly connected to the upper end of the rubber plate 44. A connecting block is provided on the outside of the electric push rod 43. The connecting block is fixedly connected to the limiting block 42. In addition, a movable frame 45 is fixedly installed on the front end of the fixed frame 41 by bolts. An electromagnetic slide rail 46 is slidably connected to the rear end of the movable frame 45. The inner end of the electromagnetic slide rail 46 is fixedly connected to the equipment body 1.

[0030] By turning on the motor installed at the bottom of the cutting blade 2, the cutting blade 2 can rotate inside the cavity opened on the upper side of the device body 1.

[0031] Then turn on the controller of the electromagnetic slide rail 46 to control the moving frame 45 to slide forward. The connection between the moving frame 45 and the electromagnetic slide rail 46 is mainly based on electromagnetic drive technology to achieve contactless sliding. The electromagnetic coil built into the electromagnetic slide rail 46 generates a magnetic field, which interacts with the magnetic material inside the rear end of the moving frame 45 to form a driving force. When the moving frame 45 slides forward, the fixed frame 41, the limit block 42 and the electric push rod 43 will move forward synchronously.

[0032] When the rear end of the moving frame 45 moves from the innermost end of the electromagnetic slide rail 46 to the innermost end of the electromagnetic slide rail 46, the controller of the electromagnetic slide rail 46 is turned off. The components such as the fixed frame 41, the limiting block 42 and the electric push rod 43 will move out of the cavity on the upper side of the equipment body 1. At this time, the distance between the limiting block 42 and the cavity is greater than the length of the circuit board. Then, the short side of the circuit board to be cut can be placed in the long slot opened in the middle of the limiting block 42, so that the short side of the circuit board is in contact with the front wall of the long slot. At this time, the contact position of the circuit board is facing down.

[0033] Then open the electric push rod 43. Using a synchronous controller, the two sets of electric push rods 43 can run synchronously. The output end of the electric push rod 43 can push the connected rubber plate 44 to move inward, so as to make contact with one end of the short side of the circuit board, thereby clamping and fixing one end of the short side of the circuit board.

[0034] Then, turn on the controller of the electromagnetic slide rail 46 to control the moving frame 45 to move backward. The circuit board held by the rubber plate 44 will also move synchronously. The circuit board is usually rectangular. When the moving frame 45 moves backward, the circuit board will also move backward. The left and right ends will contact the limiting grooves 31 inside the limiting frame 3 set on the left and right sides of the cutting blade 2 and slide inside them. The limiting grooves 31 can limit the left and right ends of the circuit board when it moves. The horizontal position of the limiting grooves 31 is slightly higher than the top of the cutting blade 2. That is, when the circuit board moves backward, the contact pins welded on its lower side will contact the cutting blade 2. At this time, the cutting blade 2 will quickly cut the contact pins welded on the lower side of the circuit board.

[0035] A cleaning mechanism 5 is provided on the outside of the cutting blade 2. The cleaning mechanism 5 includes a connecting plate 52 symmetrically arranged on the middle of the outside of the cutting blade 2. A cleaning brush 51 is installed at the lower end of the connecting plate 52. The bottom of the cleaning brush 51 is tightly attached to the lower surface of the cavity opened on the upper side inside the equipment body 1. Meanwhile, sliders are fixedly installed on the left and right sides of the outside of the connecting plate 52 by bolts. An electromagnetic slide rail 53 is slidably connected to the outside of the slider. The outside of the electromagnetic slide rail 53 is fixedly connected to the equipment body 1.

[0036] The upper part of the middle of the connecting plate 52 is located on the lower side of the outer side of the cutting blade 2, and there is a small gap between it and the cutting blade 2. This ensures that the connecting plate 52 will not be worn when the cutting blade 2 rotates. At the same time, the upper parts of the left and right sides of the middle of the connecting plate 52 are closely attached to the lower side of the limit frame 3, and the left and right sides of the connecting plate 52 are attached to the outer side of the electromagnetic slide rail 2 53.

[0037] Therefore, when the cutting blade 2 cuts the contact foot, the contact foot is facing downwards, so the cut contact foot will fall downwards. The connecting plate 52 and the cleaning brush 51 are set on the outer side of the middle of the cutting blade 2. The bottom of the cleaning brush 51 is attached to the lower surface of the inner wall of the cavity of the device body 1, which can block the falling position of the cut contact foot. It can concentrate the falling position of the contact foot cut by the cutting blade 2 on the front side of the cavity of the device body 1, and it will not exceed the central axis of the cutting blade 2.

[0038] Secondly, the cleaning brush 51 is located on the lower side of the connecting plate 52. The left side of the right cleaning brush 51 is arc-shaped and surrounds the outside of the cylindrical tube below the cutting blade 2. By activating the controller of the electromagnetic slide rail 2 53, the slider inside the electromagnetic slide rail 2 53 can be controlled to slide forward. The connection movement between the electromagnetic slide rail 2 53 and the slider is also achieved by using electromagnetic drive technology to achieve contactless sliding. At this time, the connecting plate 52 and the cleaning brush 51 will also move synchronously. The movement of the cleaning brush 51 can clean the contact feet that have fallen into the front side of the cavity on the upper side of the device body 1.

[0039] A feeding plate 54 is symmetrically installed at the lower end of the upper cavity of the equipment body 1. The feeding plate 54 is sloped, and the inner end of the feeding plate 54 is horizontally lower than the lower surface of the upper cavity of the equipment body 1. In addition, a waste bin 55 is provided below the lower end of the feeding plate 54. The outer side of the waste bin 55 is engaged with the equipment body 1. That is, the cleaning brush 51 will enter the interior of the feeding plate 54 and then enter the interior of the waste bin 55 along the slope of the feeding plate 54. The waste bin 55 is engaged with the equipment body 1, which makes it easy to remove the waste bin 55 for cleaning.

[0040] The working principle of this circuit board component contact cutting machine is as follows: A cavity is opened inside the upper side of the equipment body 1, and a cutting blade 2 is set inside the cavity. The circuit board contacts to be cut can be operated inside the cavity of the equipment body 1. An automatic feeding mechanism 4 is set on the front side of the cutting blade 2, which can automatically clamp and push the circuit board to be cut. The automatic feeding replaces the traditional manual feeding, which can effectively improve the cutting accuracy of the contacts. In addition, a cleaning mechanism 5 is set on the outside of the cutting blade 2, which can efficiently clean up the waste contact material after cutting.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
