Description

Technical Field

[0001] This invention relates to the field of component manufacturing, and more specifically to a component pin cutting device and method. Background Technology

[0002] As is well known, surface mount technology is a core process in modern electronics manufacturing. It refers to an automated assembly technology that directly mounts and solders leadless / short-lead components onto the PCB surface. When cutting the leads of components, multiple components are usually fixed between two tapes and then transported one by one to the cutting device for cutting by a conveyor.

[0003] For example, the Chinese patent document with authorization announcement number CN215508776U, announcement date 2022-01-14, and titled "Capacitor Lead Cutting and Forming Equipment," includes: a conveying device for conveying a conveyor belt carrying multiple capacitors, wherein a first cutting section is provided on the conveying device; a first pressing device configured to press against the end face of the capacitor; a cutting device having a second cutting section that can press against the first cutting section of the conveying device; a slide rail to which the cut capacitors are conveyed; a second pressing device configured to press against the end face of the capacitor; a lead clamping device having a lead clamping recess for clamping the capacitor leads; and a bending and forming device configured to bend the clamped capacitor leads. This provides a capacitor lead cutting and forming equipment that can be improved in terms of cost, efficiency, and / or quality control.

[0004] The shortcomings of existing technology are that in the process of automated circuit board production, various different components need to be cut and bent, and then the cut components are inserted into the circuit board. However, when cutting the pins of the components, the position of the cutting tool is fixed during the cutting process, which makes the reserved pin length fixed. However, the reserved pin length will change depending on the type of component. Therefore, after the components cut by the above-mentioned cutting device are inserted into the circuit board, an additional cutting device needs to be added to the bottom of the circuit board to cut off the excess pins. The process is cumbersome, and the pins are easily deformed during the cutting process, which makes it inconvenient for the subsequent installation of components. Summary of the Invention

[0005] The purpose of this invention is to provide a component pin cutting device and method to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A component pin cutting device includes a frame and a conveying mechanism disposed on the frame for feeding components, and a cutting mechanism for cutting components, the cutting mechanism including a blade holder slidably disposed on the frame and a cutting blade disposed on the blade holder; It also includes a first power assembly for driving the cutter and the cutter to slide along the frame, so that the components have pins of different lengths; It also includes a limiting and leveling component disposed on the tool holder and used to fix the pin position; The tool holder has a vertical groove, and the limiting and leveling assembly includes a transmission rod that is slidably connected to the vertical groove. A pressure plate is provided on the transmission rod. The pressure plate has a first position away from the pin and a second position that is in contact with the pin. The assembly also includes a switching component for driving the pressure plate to switch between the first position and the second position. The limiting and leveling assembly also includes a leveling rod rotatably mounted on the pressure plate, and a torsion spring is provided between the leveling rod and the pressure plate.

[0007] The aforementioned component pin cutting device includes a conveying mechanism comprising a first conveying wheel rotatably mounted on the frame.

[0008] The aforementioned component pin cutting device further includes a second conveyor wheel slidably disposed on the first conveyor wheel, and the second conveyor wheel is connected to the first conveyor wheel in a non-rotational manner, with the second conveyor wheel in contact with the cutter.

[0009] The above-mentioned component pin cutting device includes a first drive groove formed on the second conveying wheel, a first drive rod provided on the frame, the first drive rod being slidably connected to the first drive groove, and the second conveying wheel being rotatably connected to the cutter holder.

[0010] In the aforementioned component pin cutting device, a limiting structure is provided between the cutter holder and the frame to prevent them from rotating relative to each other.

[0011] The aforementioned component pin cutting device comprises two blade holders, which are symmetrically arranged on the frame.

[0012] In the aforementioned component pin cutting device, a limit block is provided on the transmission rod, and a limit groove adapted to the limit block is provided on the cutter holder.

[0013] The aforementioned component pin cutting device includes a switching assembly comprising an abutment portion disposed on the transmission rod, an abutment rod disposed on the frame, the abutment rod being located on the travel stroke of the abutment portion, and a spring disposed between the transmission rod and the cutter holder.

[0014] The aforementioned component pin cutting device includes a cutter rotatably mounted on the cutter holder, and further includes a second power component for driving the cutter to rotate intermittently.

[0015] A method for cutting component pins, which is based on the aforementioned component pin cutting device to cut the pins of the component.

[0016] In the above technical solution, the component pin cutting device provided by the present invention slides the cutting mechanism along the direction of the pin axis on the frame. When cutting various components, the cutting mechanism is controlled to slide along the direction of the frame, so that the distance between the two cutting mechanisms can be adjusted, so that the pin is reserved to a suitable length. After the pin is bent and inserted in the subsequent process, the length of the circuit board it passes through is the target length. Therefore, secondary cutting is not required, which simplifies the circuit board production process. Furthermore, when cutting the pins, fixing them with pressure plates and leveling them with leveling rods can minimize the risk of deformation of the pins themselves during the cutting process.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of this invention, it should be understood that, Figure 4 The position of the central abutment rod 14 relative to the frame 1 is upper, and vice versa. The terms "center", "longitudinal", "lateral", "length", "width", "degree", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0022] Reference Figure 1-9 The present invention provides a component pin cutting device, including a frame 1 and a conveying mechanism disposed on the frame 1 for feeding components, and a cutting mechanism for cutting components. The cutting mechanism includes a knife holder 3 slidably disposed on the frame 1 and a cutting blade 5 disposed on the knife holder 3, and a first power component for driving the knife holder 3 and the cutting blade 5 to slide along the frame 1 so that the components have pins of different lengths. It should be noted that if the pin 20 shakes during the cutting process, it will cause instability in the cutting process and reduce the cutting quality of the pin 20. To solve the above problem, a limiting and leveling component is also included, which is set on the tool holder 3 and used to fix the position of the pin 20. The tool holder 3 has a vertical groove 8. The limiting and leveling assembly includes a transmission rod 9 slidably connected to the vertical groove 8. A pressure plate 10 is provided on the transmission rod 9. The pressure plate 10 has a first position away from the pin 20 and a second position in contact with the pin 20. The assembly also includes a switching component for driving the pressure plate 10 to switch between the first position and the second position. The limiting and leveling assembly also includes a leveling rod 21 rotatably disposed on the pressure plate 10, and a torsion spring (not shown) is provided between the leveling rod 21 and the pressure plate 10.

[0023] Specifically, frame 1 (only a part of which is shown in this application) is used to install modules such as the conveying mechanism and the shearing mechanism. Components can be circuit elements such as resistors or capacitors, with pins 20 at both ends, and are arranged at equal intervals through structures such as tape and reel. Multiple components are arranged in a certain regular pattern, that is, multiple components are grouped together, and each group of components is arranged in the same order. The circuit board has through holes adapted to the pins 20. When multiple components are automatically installed on the circuit board, the components on the tape are first cut and bent, and the circuit board is fixed on a dual-axis moving mechanism. The dual-axis moving mechanism moves the through holes to below the corresponding components. Then, a robotic arm inserts the pins 20 of the components into the through holes, and another shearing mechanism at the bottom of the circuit board... Redundant pins 20 are removed before subsequent soldering, thus completing the component installation process. This is existing technology and will not be elaborated upon. One of the core innovations of this invention is that two shearing mechanisms are provided, located on both sides of the component and corresponding to the positions of the two pins 20. The shearing mechanisms are slidably mounted on the frame 1, making their shearing positions adjustable. This arrangement allows the shearing mechanisms to slide along the frame 1 when cutting various components, thereby adjusting the distance between the two shearing mechanisms. This ensures that the pins 20 are reserved to a suitable length. After the pins 20 are bent and inserted, the length of the circuit board they pass through is the target length, thus eliminating the need for secondary shearing and simplifying the circuit board manufacturing process.

[0024] Furthermore, the transmission rod 9 includes a horizontal section 901 and a U-shaped section 903. The horizontal section 901 is slidably connected to the vertical groove 8. The pressure plate 10 is positioned above the cutting position, and the pressure plate 10 has a certain length and curvature, meaning that the pressure plate 10 is sufficient to keep the pin 20 in close contact during the cutting process. The U-shaped section 903 is used to connect the pressure plate 10 to the transmission rod 9, and the U-shaped section 903 is arranged at an angle to avoid the position of the cutter 5. The leveling rod 21 is preferably a cylindrical rod, which is rotatably mounted on the side of the pressure plate 10 via a rotating shaft. The elastic force of the torsion spring causes the leveling rod 21 to tend to move closer to the pressure plate 10. The purpose of this arrangement is that, during the process of the pin 20 moving towards the position to be cut, the pressure plate 10 is in a first position away from the pin 20 to achieve avoidance. After the pin 20 moves to the bottom of the pressure plate 10, the switching component provides force to switch the pressure plate 10 from the first position to the second position. The advantages of this arrangement are, firstly, that... First, the pressure plate 10 is in contact with the pin 20, which restricts the position of the pin 20 and prevents it from wobbling, thus improving the stability of the pin 20 cutting process. Second, during the process of the pressure plate 10 switching from the first position to the second position, the leveling rod 21 will first contact the pin 20. During the subsequent downward movement of the pressure plate 10, the leveling rod 21 will slide along the surface of the pin 20. If the pin 20 at the sliding position is deformed, the leveling rod 21 can level the deformed position, which facilitates the subsequent installation of components. Third, during the process of the pressure plate 10 switching from the first position to the second position, if the pin 20 is misaligned, the pressure plate 10 can bring the misaligned pin 20 to the position of the inner wall of the tooth gap to achieve automatic correction. After the pin 20 is cut, the pressure plate 10 is controlled to switch from the second position to the first position to prepare for the cutting of the next pin 20. This process is repeated to achieve the fixing, leveling and correction of the pin 20.

[0025] Preferably, the conveying mechanism includes a first conveying wheel 2 rotatably mounted on the frame 1. Specifically, the first conveying wheel 2 is approximately gear-shaped, with the lead 20 of the component engaging with the adjacent teeth of the first conveying wheel 2. The frame 1 has a cylindrical shaft portion, and there are two first conveying wheels 2 connected by a cylindrical structure. A limiting structure is provided between the cylinder and the cylindrical shaft to prevent axial movement of the first conveying wheel 2. The cylindrical portion can be driven by a synchronous belt and a stepper motor, etc., to provide the power required for the rotation of the first conveying wheel 2. The purpose of this arrangement is that when placing the component, the tape is threaded through the slide rail, and the lead 20 of the component is inserted into the gap of the first conveying wheel 2. During the rotation of the first conveying wheel 2, the component and the lead 20 will move, thus completing the component conveying process.

[0026] Preferably, it further includes a second conveyor wheel 4 slidably disposed on the first conveyor wheel 2, and the second conveyor wheel 4 is connected to the first conveyor wheel 2 in a non-rotational manner. That is, a connection structure such as a limit bar is provided between the first conveyor wheel 2 and the second conveyor wheel 4 so that the second conveyor wheel 4 can rotate synchronously when the first conveyor wheel 2 rotates. A cutter 5 is provided on the cutter holder 3, and the second conveyor wheel 4 is in contact with the cutter 5. Specifically, the size of the second conveyor wheel 4 is adapted to the size of the first conveyor wheel 2. The cutting edge of the cutter 5 is frustum-shaped, and its end face is in contact with the end face of the second conveyor wheel 4. The cutter 5 is eccentrically arranged about the second conveyor wheel 4, that is, the cutter 5 is placed at the edge of the second conveyor wheel 4, and there is an intersection between it and the teeth of the second conveyor wheel 4. The purpose of this arrangement is that when the first conveyor wheel 2 rotates, it will drive the second conveyor wheel 4 to rotate synchronously, thereby driving the pin 20 of the component to move towards the cutter 5. When the cutter 5 contacts the pin 20, the cutting edge of the cutter 5 cuts off the pin 20 to complete the cutting process of the pin 20.

[0027] Preferably, the first power assembly includes a first drive groove 6 formed on the second conveying wheel 4, a first drive rod 7 is provided on the frame 1, the first drive rod 7 is slidably connected to the first drive groove 6, and the second conveying wheel 4 is rotatably connected to the tool holder 3, and there is a structure between the second conveying wheel 4 and the tool holder 3 to prevent axial movement between them. Specifically, the first drive rod 7 is preferably a cylindrical rod, which is fixed to the outer circumference of a circular shaft. For ease of description, considering two types of components, the unfolded view of the first drive groove 6 is approximately square wave-shaped (a square wave means that the drive groove is straight at the crest and trough positions, such as...). Figure 5As shown, the first drive groove 6 is constructed on the inner circumferential surface of the second conveyor wheel 4, with its crests and troughs arranged along the axial direction of the second conveyor wheel 4. The troughs are closer to the first conveyor wheel 2, and the crests are farther from the first conveyor wheel 2. The connecting section between the crests and troughs is inclined, and the position between the crests and troughs is set according to the type of component. That is, the difference in length between the pins 20 of the two components is the distance from the crest to the trough. This arrangement allows the first drive rod 7 to be positioned at the trough when a longer pin 20 is required. In other words, at this time, the distance between the two first conveyor wheels 2 and the two cutters 5 is... The distance between the two first conveyor wheels 2 and the two cutters 5 is further. During the rotation of the first conveyor wheel 2, the pin 20 is cut, so that the component retains a longer pin 20. After the pin 20 is cut, the first conveyor wheel 2 is controlled to continue rotating, so that the first drive rod 7 enters the inclined connecting section and then enters the crest. That is, at this time, the distance between the two first conveyor wheels 2 and the two cutters 5 is closer, so that the component retains a shorter pin 20. This process is repeated. Through the driving action between the first drive rod 7 and the first drive groove 6, the distance between the two cutters 5 can be passively switched to retain pins 20 of different lengths.

[0028] Furthermore, a limiting block 11 is provided on the transmission rod 9, and a limiting groove 12 adapted to the limiting block 11 is provided on the tool holder 3. Specifically, the limiting block 11 is a protruding part on both sides of the horizontal section 901, and the limiting groove 12 is opened on both side walls of the vertical groove 8. Under the action of the sliding connection between the limiting block 11 and the limiting groove 12, the transmission rod 9 can be prevented from moving in the axial direction of the circular shaft, thereby improving the stability of the transmission rod 9 when sliding vertically.

[0029] Preferably, the switching assembly includes an abutment portion 13 disposed on the transmission rod 9, an abutment rod 14 disposed on the frame 1, the abutment rod 14 being located on the travel stroke of the abutment portion 13, and a spring 15 disposed between the transmission rod 9 and the cutter holder 3. Specifically, for the single-sided cutting mechanism, a vertical section 902 is disposed at the end of the horizontal section 901 away from the U-shaped section 903, the abutment portion 13 is close to the bottom end of the vertical section 902, there are two abutment portions 13, and the two abutment portions 13 are respectively disposed on both sides of the vertical section 902, the upper surface of which is provided with a wedge-shaped surface, the abutment rod 14 is L-shaped, one end of which is fixed to the outer circumferential surface of the round shaft, and there are also two abutment rods 14, the positions of the two abutment rods 14 and the two abutment portions 13 are respectively aligned. The arrangement should be such that the end of the abutment rod 14 furthest from the circular shaft is located on the travel stroke of the wedge-shaped surface of the abutment portion 13. The spring 15 is disposed inside the vertical groove 8, with one end fixed to the bottom wall of the vertical groove 8 and the other end fixed to the lower surface of the horizontal section 901. The elastic force of the spring 15 causes the horizontal section 901 to tend to move towards the top wall of the vertical groove 8. This arrangement is intended to ensure that when the first power assembly drives the tool holder 3 to move axially, and under the limiting action of the limiting block 11 and the limiting groove 12, The vertical section 902 and the abutment part 13 will move horizontally synchronously. Since the position of the abutment rod 14 is fixed, the abutment part 13 will move horizontally relative to the abutment rod 14. When the wedge-shaped surface of the abutment part 13 abuts against one of the abutment rods 14, the abutment rod 14 will provide a downward pressure to the abutment part 13, thereby driving the transmission rod 9 and the pressure plate 10 to move downward and store force on the spring 15, so that the pressure plate 10 is passively switched from the first position to the second position. After the pin 20 is cut, the abutment part 13 moves in the opposite direction so that its wedge-shaped surface is away from the abutment rod 14. At this time, the elastic force of the spring 15 is released, so as to drive the transmission rod 9 and the pressure plate 10 to move upward, so as to passively switch the pressure plate 10 from the second position to the first position. When the cutter 5 cuts the pin 20 of another component, it will cause another abutment part 13 to abut against another abutment rod 14. This process is repeated to achieve the passive switching of the pressure plate 10 between the first position and the second position.

[0030] It should be noted that since the position of the cutter 5 is fixed, the position where the cutter 5 contacts the pin 20 is always the same, which can easily cause local wear of the cutter 5. To solve the above problem, as another embodiment of the present invention, the cutter 5 is rotatably mounted on the cutter holder 3, and a second power component for driving the cutter 5 to rotate intermittently is also included.

[0031] Preferably, the second power assembly includes a second drive rod 16 disposed on the cutter 5, a sleeve 17 disposed on the frame 1, and a second drive groove 18 formed on the inner wall of the sleeve 17. The second drive rod 16 is slidably connected to the second drive groove 18. Specifically, a rotating hole 19 is formed on the cutter holder 3, the cutter 5 is rotatably connected to the rotating hole 19, and a limiting mechanism such as a convex ring is provided between the two to prevent axial movement. The second drive rod 16 is fixed to the outer circumferential surface of the cutter 5, and is preferably a cylindrical rod. The sleeve 17 is fixed to the frame 1 (the part where it connects to the frame 1 is not shown). The end of the cutter 5 away from the cutting edge is rotatably connected to the sleeve 17. The second drive groove 18 is formed on the inner circumferential surface of the sleeve 17, and is approximately wavy. The width of the second drive groove 18 is greater than the radial dimension of the second drive rod 16, and the inner walls on both sides of the crest of the second drive groove 18 are staggered, as are the inner walls on both sides of the trough. Its unfolded view is shown below. Figure 9 As shown, the purpose of this arrangement is that during the horizontal movement of the blade holder 3, the cutter 5 will also move horizontally, thereby causing the second drive rod 16 to slide inside the second drive groove 18. Since the sleeve 17 is fixed to the frame 1, the sleeve 17 cannot rotate. When the second drive rod 16 abuts against the inner wall of the second drive groove 18 at a position where the peaks or troughs are offset, the cutter 5 will rotate. When the second drive rod 16 moves to a position near the outer wall of the trough or peak, the second drive rod 16 cannot move under the limiting action of the second drive groove 18, thus preventing the cutter 5 from rotating and fixing its position. This improves the stability of the pin 20 during cutting. By repeating this process, the cutter 5 can be driven to rotate intermittently during the horizontal reciprocating movement of the cutting mechanism to switch the cutting part of the cutter 5, thereby minimizing local wear on the cutter 5.

[0032] In summary, the first conveyor wheel 2 has the following strokes during rotation: first, it drives the shearing mechanism to move horizontally back and forth to adjust the length of the pin 20; second, it drives the pressure plate 10 to switch between the first position and the second position; and third, it drives the cutter 5 to rotate intermittently to switch the cutting part of the cutter 5.

[0033] Another embodiment of the present invention provides a method for cutting component pins, which is based on the above-mentioned component pin cutting device to cut the pins of components.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
