Description

Technical Field

[0001] This utility model relates to the field of component manufacturing technology, and in particular to an automatic lead cutting machine. Background Technology

[0002] In the electronics manufacturing industry, components typically have pin structures for bonding and connection. However, due to manufacturing errors, the pin lengths can vary, necessitating pin trimming. Traditional lead trimming methods often use simple cutting devices and require manual operation. This approach is not only inefficient but also struggles to guarantee pin length accuracy and consistency, impacting component soldering performance and electrical characteristics. For example, manually pressing and positioning the component during lead trimming can easily lead to dimensional deviations after trimming. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic lead cutting machine, which can not only improve lead cutting efficiency, but also ensure the accuracy and consistency of lead length.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An automatic lead-cutting machine includes: a feeding conveyor, a cutting device, an unloading conveyor, and a component transfer device. The feeding conveyor has a feeding end. The cutting device includes a cutting module and a pressing and positioning module. The pressing and positioning module is disposed on one side of the cutting module and is used to press and position the component. The cutting module is used to cut the leads on the component. The unloading conveyor has an unloading end, and the cutting device is located between the feeding conveyor and the unloading conveyor. The component transfer device includes a transfer module and a clamping module. The transfer module is connected to the clamping module. The clamping module is used to clamp and fix the component and to drive the clamping module to reciprocate between the feeding end, the cutting module, and the unloading end.

[0006] In one embodiment, the feeding and conveying device includes a feeding and conveying limiting frame, a conveying limiting belt, and a conveying drive module. The feeding and conveying limiting frame has a conveying limiting groove, the conveying limiting belt is disposed in the conveying limiting groove, the component is placed in the conveying limiting groove, and the conveying limiting belt supports the bottom of the component. The conveying drive module is connected to the conveying limiting belt and is used to drive the conveying limiting belt to rotate, so that the component moves along the conveying limiting groove to the feeding end.

[0007] In one embodiment, multiple conveyor belts are provided, with each conveyor belt spaced apart, and each conveyor belt is supported on the bottom of the component.

[0008] In one embodiment, the conveying limiting groove is further provided with a limiting groove, and the conveying limiting belt is accommodated in the limiting groove, which is used to limit the conveying limiting belt.

[0009] In one embodiment, the conveying drive module includes a drive motor structure, a main drive roller, multiple auxiliary rollers, a first end roller, and a last end roller. The first end roller and the last end roller are rotatably mounted on the feeding conveying limiting frame and are located within the conveying limiting groove. The main drive roller and each of the auxiliary rollers are respectively disposed below the conveying limiting groove. The conveying limiting belt passes through the first end roller, each of the auxiliary rollers, the main drive roller, and the last end roller to form a closed loop. The drive motor structure is connected to the main drive roller and is used to drive the main drive roller to rotate, so that the conveying limiting belt drives the components to move along the conveying limiting groove.

[0010] In one embodiment, the main drive roller, each of the auxiliary rollers, the first end roller, and the last end roller are all provided with positioning grooves, and the conveying limiting belt is accommodated in the positioning grooves.

[0011] In one embodiment, the cutting module includes a cutting positioning table and a cutting component. The cutting portion of the cutting component is located below the cutting positioning table. When a component is placed on the cutting positioning table, the pins on the component pass through the cutting positioning table and are partially located on the back side of the cutting positioning table. The pressing and positioning module is used to press and position the component so that the component is tightly attached to the cutting positioning table. The cutting component is used to cut the pins on the component.

[0012] In one embodiment, the pressing and positioning module includes a pressing mounting block, a pressing and positioning rod, a push rod, and a pressing and driving component. The pressing and mounting block is mounted on one side of the cutting module. The pressing and positioning rod is hinged to one end of the pressing and mounting block and one end of the push rod, respectively. The other end of the push rod is connected to the pressing and driving component. The pressing and driving component is used to drive the push rod to achieve linear displacement, so that the push rod pushes the pressing and positioning rod to perform pressing and positioning operations on the components on the cutting module.

[0013] In one embodiment, the pressing positioning rod includes a pressing positioning part, a first hinge part, and a second hinge part connected in sequence. The pressing positioning part is used to press the components on the cutting module.

[0016] This utility model's automatic lead-cutting machine is equipped with a feeding conveyor, a cutting device, an unloading conveyor, and a component transfer device. The component transfer device transports components from the feeding end of the feeding conveyor to the cutting device for cutting. Then, the component transfer device transports the cut components to the unloading end of the unloading conveyor, where they are unloaded. This fully automates the component cutting process, reducing manual intervention and improving cutting efficiency. Furthermore, during lead cutting, a pressing and positioning module further enhances the accuracy and consistency of the cutting process by enabling component pressing and positioning.

[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an automatic lead-cutting machine 10 includes: a feeding conveyor 100, a cutting device 200, an unloading conveyor 300, and a component transfer device 400. The feeding conveyor 100 is provided with a feeding end; the cutting device 200 includes a cutting module 210 and a pressing and positioning module 220. The pressing and positioning module 220 is disposed on one side of the cutting module 210 and is used to press and position the component. The cutting module 210 is used to cut the leads on the component 20. The cutting operation is performed; the unloading conveyor 300 is provided with an unloading end, and the cutting device 200 is located between the loading conveyor 100 and the unloading conveyor 300; the component transfer device 400 includes a transfer module 410 and a clamping module 420. The transfer module 410 is connected to the clamping module 420. The clamping module 420 is used to clamp and fix the component 20. The transfer module 410 is used to drive the clamping module 420 to reciprocate between the loading end, the cutting module 210 and the unloading end.

[0027] It should be noted that when the pins of component 20 need to be cut, component 20 is first loaded by the feeding conveyor 100, moving it to the loading end; then, the clamping module 420 above the loading end clamps and fixes component 20. After clamping and fixing, component 20 is moved from the clamping module 420 to the cutting module 210 of the cutting device 200 by the transfer module 410. Then, the pressing and positioning module 220 presses and positions the cutting module 210. The component 20 on the cutting module 210 is pressed and positioned to ensure that the bottom surface of the component 20 is tightly fitted with the cutting module 210, preventing the component 20 from shifting during the cutting process. This ensures consistent cutting dimensions and improves cutting accuracy and consistency. After the lead-cutting operation is completed, the transfer module 410, in conjunction with the clamping module 420, transfers the lead-cut component 20 to the unloading conveyor 300, where it is uniformly unloaded. This achieves automatic lead-cutting of the component 20, replacing manual or semi-automatic lead-cutting operations, reducing human intervention, improving production efficiency, and ensuring the accuracy and consistency of cutting dimensions.

[0028] Please see Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the feeding and conveying device 100 includes a feeding and conveying limiting frame 110, a conveying limiting belt 120, and a conveying drive module 130. The feeding and conveying limiting frame 110 has a conveying limiting groove 111. The conveying limiting belt 120 is disposed in the conveying limiting groove 111. The component 20 is placed in the conveying limiting groove 111, and the conveying limiting belt 120 supports the bottom of the component 20. The conveying drive module 130 is connected to the conveying limiting belt 120 and is used to drive the conveying limiting belt 120 to rotate so that the component 20 moves along the conveying limiting groove 111 to the feeding end.

[0029] It should be noted that by setting a conveyor limiting groove 111 on the feeding conveyor limiting frame 110, the two sides of the component 20 can be limited by the conveyor limiting groove 111 to prevent the component 20 from shifting position. In addition, since the component 20 has pins at the bottom, if the component 20 is placed directly in the conveyor limiting groove 111 and the pins of the component 20 are in direct contact with the conveyor limiting groove 111, the component 20 will not be placed stably, resulting in positional shift or tilting and collapse. This will prevent the subsequent clamping module 420 from performing normal clamping operation on the component 20, and may also damage the component 20. To prevent pin damage from compression, this embodiment employs a conveyor limiting belt 120 on the conveyor limiting groove 111. This belt supports the bottom of the component 20, allowing the pins of the component 20 to remain suspended relative to the bottom of the conveyor limiting groove 111. This prevents direct contact between the pins and the bottom of the conveyor limiting groove 111, ensuring the stability and accuracy of the component 20's placement. Simultaneously, the conveyor drive module 130 moves the conveyor limiting belt 120, allowing the component 20 on the belt to move along the conveyor limiting groove 111 to the loading end. This not only ensures stable conveying of the component 20 and accurate positioning but also prevents pin damage from contact with the conveyor limiting groove 111.

[0030] Furthermore, multiple conveyor limiting belts 120 are provided, with each conveyor limiting belt 120 spaced apart and supported on the bottom of the component 20. The number of conveyor limiting belts 120 can be selected to match the size specifications of the component 20. In this embodiment, there are three conveyor limiting belts 120, which are spaced apart, so that the pins of the component 20 are suspended when supporting the component 20.

[0031] Please see Figure 2 and Figure 3As shown, the conveying limiting groove 111 further includes a limiting groove 111a, within which the conveying limiting belt 120 is housed. The limiting groove 111a is used to limit the conveying limiting belt 120. This prevents the conveying limiting belt 120 from shifting position or swaying during the transport of the component 20, thereby improving the stability and accuracy of the component 20's transport. In this embodiment, the conveying limiting groove 111 also includes a pin-avoiding groove 111b, located on one side of the limiting groove 111a, i.e., on one side of the conveying limiting belt 120. When the conveying limiting belt 120 carries the component 20, the pins of the component 20 are located within the pin-avoiding groove 111b, leaving the pins suspended and preventing scratch or compression damage.

[0032] Please see Figure 2 As shown, in one embodiment, the conveying drive module 130 includes a drive motor structure 131, a main drive roller 132, multiple auxiliary rollers 133, a first end roller 134, and a last end roller 135. The first end roller 134 and the last end roller 135 are rotatably mounted on the feeding conveying limit frame 110, and the first end roller 134 and the last end roller 135 are located in the conveying limit groove 111. The main drive roller 132 and each auxiliary roller 133 are respectively disposed below the conveying limit groove 111. The conveying limit belt 120 passes through the first end roller 134, each auxiliary roller 133, the main drive roller 132, and the last end roller 135 to form a closed loop. The drive motor structure 131 is connected to the main drive roller 132 and is used to drive the main drive roller 132 to rotate so that the conveying limit belt 120 drives the component 20 to move along the conveying limit groove 111.

[0033] It should be noted that two auxiliary rollers 133 are provided, located on both sides of the main drive roller 132, and working in conjunction with the first end roller 134 and the last end roller 135 to ensure the tension of the conveyor limit belt 120. When the drive motor structure 131 is started, it drives the main drive roller 132 to rotate, causing the conveyor limit belt 120 to rotate. This, in conjunction with the auxiliary rollers 133, the first end roller 134, and the last end roller 135, enables the movement of the conveyor limit belt 120, thereby driving the movement of the component 20. In this embodiment, the main drive roller 132, each auxiliary roller 133, the first end roller 134, and the last end roller 135 are provided with positioning grooves. The conveyor limit belt 120 is housed within these positioning grooves, thus preventing positional deviation of the conveyor limit belt 120. In this embodiment, the conveyor limit belt 120 can be made of rubber and has a circular structure.

[0034] In one embodiment, to improve automation and ensure the accuracy of the stopping position of component 20, a fiber optic sensor 140 is installed on the feeding conveyor limit frame 110. For example, the fiber optic sensor 140 is installed on the feeding end or other positions where stopping needs to be controlled. When the fiber optic sensor detects that component 20 is placed on the feeding end, it controls other components to start operating or controls the feeding conveyor 100 to stop.

[0035] In one embodiment, the structure of the loading conveyor limit frame 110 is the same as that of the unloading conveyor limit frame.

[0036] Due to factors such as shaking during the conveying of component 20 by the feeding conveyor 100, the gripping module 420 on the component transfer device 400 cannot guarantee the accuracy of the position from the feeding end to the cutting device 200 when gripping and transporting component 20. If component 20 is offset, the component transfer device 400 will be unable to smoothly place component 20 into the cutting positioning area on the cutting device 200. Therefore, before the cutting device 200 is used, the position of component 20 needs to be further adjusted. Please refer to [link / reference]. Figure 1 and Figure 5 As shown, the automatic lead cutting machine 10 also includes a positioning adjustment device 500, which is located between the feeding conveyor 100 and the cutting device 200. The positioning adjustment device 500 is used to adjust the position of the component 20. In this way, the accuracy of the component transfer device 400 in transferring the component 20 to the cutting module 210 can be ensured.

[0037] Specifically, the positioning adjustment device 500 includes a positioning support platform 510, a positioning adjustment component 520, and a positioning adjustment drive component 530. The top surface of the positioning support platform 510 has a clearance through hole, and the positioning support platform 510 has a drive component mounting cavity. The clearance through hole communicates with the drive component mounting cavity. The positioning adjustment component 520 is located on the clearance through hole, and the positioning adjustment drive component 530 is located within the drive component mounting cavity and connected to the positioning adjustment component 520. The positioning adjustment drive component 530 is used to drive the positioning adjustment component 520 to adjust the position of the component 20. In this embodiment, the positioning adjustment component 520 includes multiple positioning blocks 521, each positioning block 521 forming a positioning area. The component 20 is located on the positioning area, and each positioning block 521 is connected to the positioning adjustment drive component 530. The positioning adjustment drive component 530 is used to drive each positioning block 521 to move closer to or further away from the component 20. In this embodiment, the positioning and adjustment drive component 530 is a four-jaw cylinder. Correspondingly, four positioning blocks 521 are provided, each connected to one of the four drive ends of the four-jaw cylinder. Using a four-jaw cylinder facilitates the synchronous movement of each positioning block 521, thereby ensuring the uniformity of the clamping force of the positioning blocks 521 on each clamping part of the component 20. In this embodiment, to avoid scratching or pinching damage to the component 20 when clamping it, the positioning blocks 521 are made of cushioning rubber.

[0038] Please see Figure 4 As shown, in one embodiment, the cutting module 210 includes a cutting positioning table 211 and a cutting component 212. The cutting part of the cutting component 212 is located below the cutting positioning table 211. When a component 20 is placed on the cutting positioning table 211, the pins on the component 20 pass through the cutting positioning table 211 and are partially located on the back side of the cutting positioning table 211. The pressing positioning module 220 is used to press and position the component 20 so that the component 20 is tightly attached to the cutting positioning table 211. The cutting component 212 is used to cut the pins on the component 20.

[0039] It should be noted that the cutting positioning stage 211 is provided with a cutting positioning cavity 211a, and the cutting positioning cavity 211a has pin positioning holes 211b. The component 20 is placed on the cutting positioning cavity 211a, and the pins of the component 20 are respectively accommodated in the pin positioning holes 211b and partially located on the back side of the cutting positioning stage 211. Then, the component 20 can be pressed and positioned by the pressing positioning module 220 to make the component 20 fit tightly with the cutting positioning stage 211, so as to prevent the component 20 from moving during the cutting process and thus ensure the consistency of the cutting size. Then, the pins on the component 20 are cut by the cutting component 212. Specifically, the cutting component 212 includes a cutting blade and a cutting drive cylinder. The cutting blade is connected to the cutting drive cylinder, and the cutting drive cylinder drives the cutting blade to cut the pins of the component 20. In this embodiment, the cutting module 210 also includes a waste collection box 213, which is located below the cutting positioning table 211. The waste material cut off by the cutting part 212 will fall directly onto the waste collection box 213, thereby facilitating the centralized collection of waste and avoiding waste pollution of the production environment.

[0040] It should also be noted that, in one embodiment, the cutting and positioning table 211 includes a cutting base and a component positioning block. The cutting base is provided with a mounting cavity, and the component positioning block is detachably mounted on the cutting base. In this way, the component positioning block can be replaced according to different specifications of components 20, thereby enabling the automatic lead cutting machine 10 to perform lead cutting operations on components 20 of various specifications, improving the versatility of the automatic lead cutting machine 10.

[0041] Please see Figure 4 As shown, in one embodiment, when the pins of component 20 are cut, the applied cutting force causes the component 20 to shift, resulting in a large deviation in the cutting dimensions. Therefore, a pressing and positioning module 220 is needed to press and position the component 20. Specifically, the pressing and positioning module 220 includes a pressing mounting block 221, a pressing and positioning rod 222, a push rod 223, and a pressing drive component 224. The pressing mounting block 221 is mounted on one side of the cutting module 210. The pressing and positioning rod 222 is hinged to one end of the pressing mounting block 221 and one end of the push rod 223. The other end of the push rod 223 is connected to the pressing drive component 224. The pressing drive component 224 is used to drive the push rod 223 to achieve linear displacement, so that the push rod 223 pushes the pressing and positioning rod 222 to press and position the component 20 on the cutting module 210. In this embodiment, the pressing drive 224 can be a cylinder. When the driving end of the cylinder extends, the push rod 223 pushes the pressing positioning rod 222 to press the top surface of the component 20, thereby realizing the pressing and positioning operation of the component 20.

[0042] Please see Figure 4 As shown, in one embodiment, the pressing positioning rod 222 includes a pressing positioning part, a first hinge part, and a second hinge part connected in sequence. The pressing positioning part is used to perform a pressing operation on the component 20 on the cutting module 210. The first hinge part is hinged to the pressing mounting block 221, and the second hinge part is hinged to one end of the push rod 223. When the push rod 223 pushes the pressing positioning rod 222, the first hinge part rotates relative to the pressing mounting block 221, and the second hinge part rotates relative to the push rod 223.

[0043] In one embodiment, a buffer rubber block is provided on the side of the pressing and positioning part facing the cutting module 210. When the pressing and positioning part performs a pressing operation on the component 20 on the cutting module 210, the buffer rubber block contacts and abuts against the top surface of the component 20. In this way, the buffer rubber block can prevent damage to the surface of the component 20.

[0044] Please see Figure 6 As shown, in one embodiment, the transplanting module 410 includes a support base 411, a lifting plate 412, a transverse moving plate 413, and a transplanting drive component 414. The support base 411 is provided with a lifting slide rail, the lifting plate 412 is slidably disposed on the lifting slide rail, the lifting plate 412 is provided with a transverse slide rail, and the transverse moving plate 413 is slidably disposed on the transverse slide rail. The clamping module 420 is installed on the transverse moving plate 413. The transplanting drive component 414 is connected to the transverse moving plate 413. The transplanting drive component 414 is used to drive the transverse moving plate 413 to achieve reciprocating transverse displacement along the transverse slide rail, and also to drive the lifting plate 412 to achieve reciprocating lifting displacement along the lifting slide rail.

[0045] It should be noted that when the clamping module 420 clamps the component 20 from the loading end, the transfer drive 414 is activated, and the lifting plate 412 and the transverse moving plate 413 move simultaneously. At this time, the lifting plate 412 rises, and the transverse moving plate 413 moves towards the cutting device 200, thereby transferring the component 20 to the next workstation. Specifically, the transfer drive 414 includes a servo motor 414a and a rotating block 414b. The servo motor 414a is mounted on the side of the support base 411 away from the lifting plate 412, and the drive end of the servo motor 414a passes through the support base 411 and is connected to one end of the rotating block 414b. The other end of the rotating block 414b is connected to the transverse moving plate 413 through a connecting shaft. When the servo motor 414a starts, its drive end drives the rotating block 414b to rotate around the drive end of the servo motor 414a. This causes the lifting plate 412 to move up and down along the lifting slide rail, while the transverse moving plate 413 moves laterally along the transverse slide rail. This allows the clamping module 420 to perform the transfer operation on the component 20. Thus, the transfer module 410 ensures the linkage of all transfer actions, improving transfer efficiency and reducing the use of drive components, resulting in a more compact overall structure.

[0046] To avoid damage to component 20 caused by the gripper 421 during loading and unloading, please refer to [link to relevant documentation]. Figure 6 and Figure 7 As shown, in one embodiment, the gripping module 420 includes grippers 421 and anti-pressure component 422. The anti-pressure component 422 is disposed on the transplanting module 410, and the grippers 421 are disposed on the anti-pressure component 422.

[0047] It should be noted that when the gripper 421 picks up the component 20 and places it on each workstation, the machine itself has a certain error. Even if the machine's own error is within a controllable range, the position of the component 20 will still have an error. When the machine's own error and the positional error of the component 20 exist, it will be impossible to ensure that the pins on the component 20 are completely aligned with the pin positioning holes 211b when the gripper 421 picks up the component 20 and places it on the transfer module 410. If the transfer module 410 drives the gripper 421 to directly insert the pins on the component 20 into the pin limiting holes, it may cause the pins of the component 20 to bend or be damaged, reducing the yield of the component 20. Therefore, by adding the anti-pressure component 422, a buffer and anti-pressure function can be provided when the gripper 421 picks up and places the component 20.

[0048] Specifically, the anti-pressure assembly 422 includes an anti-pressure moving plate 422a, a buffer spring rod 422b, and a sensor 422c. A first mounting block is provided on the transplanting module 410, and one end of the buffer spring rod 422b is mounted on the first mounting block. A second mounting block is provided on the anti-pressure moving plate 422a, and the other end of the buffer spring rod 422b is mounted on the second mounting block. An anti-pressure guide rail 415 is also provided on the transplanting module 410. An anti-pressure guide block is provided on the side of the anti-pressure moving plate 422a facing the anti-pressure guide rail 415, and the anti-pressure guide block is slidably connected to the anti-pressure guide rail 415. The sensor 422c is located on one side of the transplanting module 410, and a sensing element 422d is provided on the anti-pressure moving plate 422a. When the gripper 421 is subjected to upward pressure, the anti-pressure moving plate 422a moves away from the pressure surface along the anti-pressure guide rail 415. Simultaneously, the spring on the buffer spring rod 422b is compressed, causing the sensing element 422d on the anti-pressure moving plate 422a to move to the recognition end of the sensor 422c. The sensor 422c transmits a signal to control the transfer module 410 to stop operating or issue an alarm, thus preventing the gripper 421 from further lowering the component 20, avoiding pressure damage to the component 20, and thus playing a role in preventing pressure and improving product yield. When the pressure is released, the buffer spring rod 422b resets the anti-pressure moving plate 422a to its initial position. The sensor 422c can be a fiber optic sensor.

[0049] Please see Figure 6 As shown, in one embodiment, the gripper 421 includes a gripper cylinder 421a and two clamping blocks 421b. The two clamping blocks 421b are respectively disposed on the two drive ends of the gripper cylinder 421a, thereby realizing the gripping operation of the component 20. A buffer rubber block is provided on the clamping surface of the clamping block to prevent damage to the outer surface of the component 20.

[0050] In one embodiment, multiple gripping modules 420 are provided, each gripping module 420 corresponding to an operating station, thereby enabling each station to work simultaneously, reducing the waiting time for materials at each station, and thus improving production efficiency. In this embodiment, three gripping modules 420 are provided.

[0051] In one embodiment, the automatic foot cutting machine 10 is also equipped with an operation screen, through which the working status of the automatic foot cutting machine 10 can be monitored in real time.
