Description

Technical Field

[0001] This application relates to the field of circuit board processing, and in particular to a circuit board cutting device. Background Technology

[0002] A circuit board is a substrate used to connect and support electronic components. When processing circuit boards, it is necessary to cut continuous strip circuit boards into sheet circuit boards of a predetermined size and shape.

[0003] In related technologies, existing circuit board cutting equipment uses a cylinder to drive a cutter to reciprocate along the vertical direction of the circuit board, and a drive motor to feed the circuit board. By alternating between the cylinder and the drive motor, the circuit board cutting equipment can continuously cut the circuit board. However, when cutting circuit boards using existing circuit board cutting equipment, the production cost is too high because the existing circuit board cutting equipment requires the simultaneous use of a cylinder and a drive motor. Furthermore, the cylinder and drive motor need to work alternately, and both cylinder and drive motor have long waiting times, resulting in reduced working efficiency of the cylinder and drive motor in the circuit board cutting equipment. Summary of the Invention

[0004] In order to reduce the production cost of circuit board cutting equipment and improve its working efficiency, this application proposes a circuit board cutting device.

[0005] The circuit board cutting device provided in this application adopts the following technical solution:

[0006] A circuit board cutting device includes: a driving mechanism having a power output end; a cutting mechanism including a first cutting component and a second cutting component spaced apart along a first direction of the circuit board cutting device, with a cutting gap between the first cutting component and the second cutting component, the cutting gap being suitable for a circuit board to pass through; and a feeding mechanism including a feeding component movably disposed along a second direction of the circuit board cutting device, the feeding component being spaced apart from the cutting mechanism along the second direction, and wherein when the feeding component moves toward the cutting mechanism, it causes the circuit board to move toward the cutting mechanism, and when the feeding component moves away from the cutting mechanism, it interacts with the circuit board. The road surface is separated, wherein the first direction and the second direction are arranged perpendicular to each other; the transmission mechanism includes a transmission rod group, which is tractively connected between the power output end, the first cutting component and the feeding component. When the transmission rod group is driven by the driving mechanism, it reciprocates between a first position and a second position. When the transmission rod group moves from the first position toward the second position, it causes the first cutting component to move closer to the second cutting component and causes the feeding component to move away from the cutting mechanism. When the transmission rod group moves from the second position toward the first position, it causes the first cutting component to move away from the second cutting component and causes the feeding component to move closer to the cutting mechanism.

[0007] By adopting the above technical solution, and by using the drive mechanism to simultaneously drive the first cutting component and the feeding component through the transmission rod group, the circuit board cutting equipment can continuously cut and transport circuit boards. Compared with the prior art, the number of drive devices in the circuit board cutting equipment can be reduced, and the drive mechanism can work continuously, reducing the waiting time of the drive mechanism. This can reduce the production cost of the circuit board cutting equipment and improve the working efficiency of the drive mechanism.

[0008] Preferably, the transmission mechanism further includes a crank, the transmission rod assembly has a plurality of transmission rods connected in sequence, the power output end is fixedly connected to one end of the crank, and the transmission rod located at the head of the plurality of transmission rods connected in sequence is pivotally connected to the other end of the crank, so as to drive the crank to rotate through the power output end, thereby driving the transmission rod assembly to reciprocate between the first position and the second position.

[0009] By adopting the above technical solution, the power output end and one end of the crank are fixedly connected, so that the power output end can drive the crank to rotate. The other end of the crank is connected to the transmission rod assembly. During the cyclic rotation of the crank, the transmission rod assembly is driven to reciprocate between the first position and the second position. This can achieve the technical effect of continuous transport and cutting of circuit boards by the circuit board cutting equipment, thereby improving the working efficiency of the circuit board cutting equipment.

[0010] Preferably, along the first direction, the crank is located on the side of the first cutting assembly away from the second cutting assembly. The transmission rod assembly includes a first transmission rod and a second transmission rod. The first transmission rod is tractively connected between the crank and the first cutting assembly, and the second transmission rod is tractively connected between the first cutting assembly and the feeding assembly. The crank is adapted to drive the first transmission rod to move the first cutting assembly and the second transmission rod along the first direction, and when the second transmission rod is driven by the first transmission rod, it drives the feeding assembly to move along the second direction.

[0011] By adopting the above technical solution, and by using a crank to drive the first transmission rod, which in turn drives the first cutting component and the second transmission rod, and the second transmission rod to drive the feeding component, the first cutting component can move along the first direction of the circuit board cutting equipment while the feeding component moves along the second direction of the circuit board cutting equipment. The first cutting component and the feeding component can move synchronously, thereby improving the coordination between the cutting component and the feeding component, and thus improving the processing efficiency of the circuit board cutting equipment.

[0012] Preferably, the cutting mechanism further includes a first guide member, which extends along the first direction, and the first cutting component is guided and cooperates with the first guide member.

[0013] By adopting the above technical solution, the first cutting component can move along the first direction of the circuit board cutting equipment through the guiding cooperation between the first cutting component and the first guide component. This can avoid deviation in the movement of the cutting mechanism, improve the cutting accuracy of the cutting mechanism, help improve the product consistency of the circuit board, and thus improve the product quality of the circuit board.

[0014] Preferably, the first cutting assembly includes a first moving seat, a connecting member, and a first cutter. The first moving seat is guided and engaged with the first guiding member. The connecting member and the first cutter are both disposed on the first moving seat. The connecting member has a connecting portion and a pivot shaft. The connecting portion is connected and engaged with the first moving seat. The first transmission rod and the second transmission rod are both pivotally connected to the pivot shaft. The first cutter is disposed close to the cutting gap.

[0015] By adopting the above technical solution, the first moving seat can move along the first direction of the circuit board cutting equipment through the guiding cooperation between the first moving seat and the first guide member. The first transmission rod and the second transmission rod are both pivotally connected to the pivot shaft. The end of the first transmission rod away from the crank can drive the first moving seat to move through the connecting member, and the end of the first transmission rod away from the crank can drive the second transmission rod to move through the pivot shaft. In turn, the second transmission rod can drive the feeding assembly to move so that the feeding assembly can transport the circuit board.

[0016] Preferably, the second cutting assembly includes a fixing base and a second cutter, the second cutter being disposed on the fixing base and close to the cutting gap, and the first cutter and the second cutter being disposed opposite to each other along the second direction.

[0017] By adopting the above technical solution, the first cutter and the second cutter are arranged opposite to each other in the second direction of the circuit board cutting device, so that the first cutter and the second cutter cooperate in the second direction to cut the circuit board to be cut, thereby realizing the cutting of the circuit board.

[0018] Preferably, the feeding mechanism further includes a second guide member, which extends along the second direction, and the feeding assembly is guided and cooperated with the second guide member.

[0019] By adopting the above technical solution, the feeding component and the second guide can guide the feeding component to move accurately along the second direction of the circuit board cutting equipment. The contact position and separation position between the feeding component and the circuit board meet the preset requirements, which can ensure that the feeding component transports the circuit board to the preset cutting position. This allows the circuit board cutting equipment to cut circuit boards that meet the preset shape and size, further improving the product consistency of the circuit boards and enhancing the product quality of the circuit boards.

[0020] Preferably, the feeding assembly includes a second moving seat, a pivot member, and a feeding member. The second moving seat has a first pivot portion and is guided and engaged with the second guide member. The pivot member has a first rotating arm, a second pivot portion, and a second rotating arm. The second pivot portion is connected between the first rotating arm and the second rotating arm. The first rotating arm is pivotally connected to the end of the second transmission rod away from the first cutting assembly. The first pivot portion is pivotally connected to the second pivot portion. The feeding member is mounted on the second rotating arm. When the pivot member is driven by the second transmission rod, it is adapted to drive the feeding member to rotate around the rotation axis of the second pivot portion. The feeding member is configured to extend into the feeding hole of the circuit board when the second moving seat moves close to the cutting mechanism, and to extend out of the feeding hole of the circuit board when the second moving seat moves away from the cutting mechanism.

[0021] By adopting the above technical solution, the second pivot part can connect the first rotating arm and the second rotating arm, so that both the first rotating arm and the second rotating arm can rotate around the second pivot part. Under the drive of the second transmission rod, the pivot part drives the feeding part to rotate around the rotation axis of the second pivot part, so that the feeding part extends into / out of the feeding hole of the circuit board. The feeding part is set close to the circuit board, which can shorten the interval between the feeding part and the circuit board, making it easier for the feeding part to cooperate with the circuit board to transport the circuit board.

[0022] Preferably, when the transmission rod assembly is in the first position, the distance between the first cutting component and the second cutting component along the first direction is the largest, and the distance between the feeding component and the cutting mechanism along the second direction is the smallest; when the transmission rod assembly is in the second position, the distance between the first cutting component and the second cutting component along the first direction is the smallest, and the distance between the feeding component and the cutting mechanism along the second direction is the largest.

[0023] By adopting the above technical solution, when the transmission rod assembly moves from the first position to the second position, the first cutting component moves closer to the second cutting component and drives the feeding component to move away from the cutting mechanism, so as to achieve the technical effect of cutting the circuit board. When the transmission rod assembly moves from the second position to the first position, the first cutting component moves away from the second cutting component and drives the feeding component to move closer to the cutting mechanism, so as to achieve the technical effect of moving the circuit board. This can avoid interference between the feeding component and the cutting mechanism and improve the overall coordination of the circuit board cutting equipment.

[0024] Preferably, the circuit board cutting equipment further includes a mounting bracket, and both the cutting mechanism and the feeding mechanism are mounted on the mounting bracket. The driving mechanism includes a drive motor, a transmission belt, and a drive shaft. The drive shaft is located on the upper side of the top wall of the mounting bracket and has the power output end. The drive motor is located on the bottom wall of the mounting bracket. The transmission belt is located between the drive motor and the drive shaft and is adapted to transmit the power generated by the drive motor to the drive shaft.

[0025] By adopting the above technical solution, when the circuit board cutting equipment processes and cuts circuit boards, by setting the cutting mechanism and the feeding mechanism on the mounting bracket, and by setting the drive motor close to the bottom of the circuit board cutting equipment, the center of gravity of the drive motor on the circuit board cutting equipment can be reduced, thereby making the drive motor run more stably on the circuit board cutting equipment. The drive motor, transmission belt and drive shaft work together to achieve the technical effect of the drive motor outputting power over a long distance, and the transmission mechanism can receive the driving force.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Driven by the drive mechanism, the first cutting component and the feeding component are simultaneously driven by the transmission rod group, which enables the circuit board cutting equipment to continuously cut and transport circuit boards. Compared with the prior art, the number of drive devices in the circuit board cutting equipment can be reduced, and the drive mechanism can work continuously, reducing the waiting time of the drive mechanism. This can reduce the production cost of the circuit board cutting equipment and improve the working efficiency of the drive mechanism.

[0028] 2. By fixing the power output end to one end of the crank, the power output end can drive the crank to rotate. The other end of the crank is connected to the transmission rod assembly. During the cyclic rotation of the crank, the transmission rod assembly is driven to reciprocate between the first and second positions. This enables the circuit board cutting equipment to continuously transport and cut circuit boards, thereby improving the working efficiency of the circuit board cutting equipment.

[0029] 3. By using a crank to drive the first transmission rod, which in turn drives the first cutting component and the second transmission rod, and the second transmission rod drives the feeding component, the first cutting component can move along the first direction of the circuit board cutting equipment while the feeding component moves along the second direction of the circuit board cutting equipment. The first cutting component and the feeding component can move synchronously, thereby improving the coordination between the cutting component and the feeding component, and thus improving the processing efficiency of the circuit board cutting equipment.

[0047] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0048] This application discloses a circuit board cutting device 100. The circuit board cutting device 100 has a mounting bracket 5. The cutting mechanism 2 and the feeding mechanism 3 of the circuit board cutting device 100 can both be mounted on the mounting bracket 5. The mounting bracket 5 can be placed or fixed on the ground. The mounting bracket 5 can support and fix the various components of the circuit board cutting device 100. The circuit board cutting device 100 is used to cut continuous circuit boards 200 to be cut into sheet-shaped circuit boards 200 of preset size and shape.

[0049] Reference Figures 1-8The circuit board cutting device 100 described in this application embodiment includes: a drive mechanism 1, a cutting mechanism 2, a feeding mechanism 3, and a transmission mechanism 4. The drive mechanism 1 has a power output end, and the drive mechanism 1 can output power through the power output end. Specifically, the drive mechanism 1 includes a drive motor 11, a transmission belt 12, and a drive shaft 13. The drive shaft 13 has a power output end, and the transmission belt 12 is disposed between the drive motor 11 and the drive shaft 13 and is adapted to transmit the power generated by the drive motor 11 to the drive shaft 13. The end of the drive shaft 13 furthest from the power output end is connected to the transmission belt 12, and the power output by the drive motor 11 can be transmitted to the outside of the drive mechanism 1 sequentially through the transmission belt 12 and the drive shaft 13.

[0050] Furthermore, the cutting mechanism 2 is used to cut the continuous circuit board 200 into sheet-shaped circuit boards 200. The cutting mechanism 2 includes a first cutting component 21 and a second cutting component 22 spaced apart along a first direction of the circuit board cutting device 100. It should be noted that the first direction of the circuit board cutting device 100 may refer to the height direction of the circuit board cutting device 100. Figure 3 In the vertical direction, the first cutting component 21 and the second cutting component 22 are arranged opposite to each other along the first direction of the circuit cutting device. The first cutting component 21 and the second cutting component 22 can generate relative movement. When the first cutting component 21 and the second cutting component 22 are separated, a cutting gap is formed between the first cutting component 21 and the second cutting component 22. The cutting gap is suitable for the circuit board 200 to pass through. After the continuous strip-shaped circuit board 200 passes through the cutting gap, it moves to a suitable cutting position. The cutting mechanism 2 can cut the circuit board 200 after the circuit board 200 moves to the suitable cutting position. In this way, the circuit board 200 formed by cutting can be the same as the preset size and shape.

[0051] The feeding mechanism 3 includes a feeding component 31, which is movably arranged along the second direction of the circuit board cutting device 100. It should be noted that the first and second directions of the circuit board cutting device 100 are perpendicular to each other. The second direction of the circuit board cutting device 100 can refer to the length direction of the circuit board cutting device 100. Figure 4In the front-back direction, the feeding component 31 and the cutting mechanism 2 are spaced apart along the second direction of the circuit board cutting equipment 100. When the feeding component 31 moves close to the cutting mechanism 2, it drives the circuit board 200 to move close to the cutting mechanism 2. When the feeding component 31 moves away from the cutting mechanism 2, it separates from the circuit board 200. Thus, after the feeding component 31 transports the circuit board 200 to the preset cutting position, the feeding component 31 separates from the circuit board 200. By making the feeding component 31 reciprocate along the second direction of the circuit board cutting equipment 100, the feeding component 31 can continuously transport the circuit board 200 to the cutting mechanism 2, thus achieving the technical effect of automatic feeding of the circuit board cutting equipment 100.

[0052] Meanwhile, the transmission mechanism 4 includes a transmission rod assembly 41, which is connected between the power output end, the first cutting component 21 and the feeding component 31. When the transmission rod assembly 41 is driven by the drive mechanism 1, it reciprocates between the first position and the second position. The transmission rod assembly 41 is connected and cooperates with the power output end of the drive shaft 13. The power generated by the drive motor 11 is output to the transmission rod assembly 41 through the power output end of the drive shaft 13 to drive the transmission rod assembly 41 to move.

[0053] It should be noted that when the transmission rod assembly 41 is in the first position, the distance between the first cutting component 21 and the second cutting component 22 along the first direction is the largest, and when the transmission rod assembly 41 is in the second position, the distance between the first cutting component 21 and the second cutting component 22 along the first direction is the smallest. When the transmission rod assembly 41 moves from the first position to the second position, it drives the first cutting component 21 to move closer to the second cutting component 22 and drives the feeding component 31 to move away from the cutting mechanism 2. At this time, the first cutting component 21 and the second cutting component 22 jointly cut the circuit board 200 and the feeding component 31 is separated from the circuit board 200.

[0054] When the transmission rod assembly 41 moves from the second position toward the first position, it drives the first cutting assembly 21 away from the second cutting assembly 22 and drives the feeding assembly 31 to move closer to the cutting mechanism 2. At this time, the first cutting assembly 21 and the second cutting assembly 22 separate and form a cutting gap, and the feeding assembly 31 transports the circuit board 200 to the preset cutting position.

[0055] Therefore, by using the drive mechanism 1 to simultaneously drive the first cutting component 21 and the feeding component 31 through the transmission rod group 41, the circuit board cutting equipment 100 can continuously cut and transport the circuit board 200. Compared with the prior art, the number of drive devices in the circuit board cutting equipment 100 can be reduced, and the drive mechanism 1 can work continuously, reducing the waiting time of the drive mechanism 1. This can reduce the production cost of the circuit board cutting equipment 100 and improve the working efficiency of the drive mechanism 1.

[0056] See Figure 1 , Figure 3 and Figure 7 In some embodiments of this application, the transmission mechanism 4 further includes a crank 42; in some specific embodiments, the crank 42 may also be configured as an eccentric wheel. The transmission rod assembly 41 has a plurality of sequentially connected transmission rods, such as... Figure 1 In the embodiment shown, there can be two transmission rods. The power output end is fixedly connected to one end of the crank 42. Specifically, the end wall of the crank 42 near the power output end is provided with a mounting groove. The mounting groove and the power output end are arranged opposite to each other. The drive shaft 13 can be inserted into the mounting groove, so as to achieve the technical effect of transmission connection between the transmission mechanism 4 and the drive mechanism 1.

[0057] In a plurality of sequentially connected transmission rods, the first transmission rod is pivotally connected to the other end of the crank 42. In some embodiments, the other end of the crank 42 may be provided with a first pivot shaft 421. The first transmission rod in the transmission rod group 41 is pivotally connected to the first pivot shaft 421. The drive mechanism 1 drives the crank 42 to rotate, thereby driving the first transmission rod in the plurality of sequentially connected transmission rods to move, and thus driving the plurality of sequentially connected transmission rods to move. By driving the crank 42 to rotate through the power output end, the crank 42 drives the transmission rod group 41 to reciprocate between the first position and the second position during the cyclic rotation, which can achieve the technical effect of continuous transport and cutting of the circuit board 200 by the circuit board cutting equipment 100.

[0058] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments of this application, along the first direction of the circuit board cutting device 100 ( Figure 3 (Up and down direction), crank 42 is located on the side of the first cutting assembly 21 away from the second cutting assembly 22, the transmission rod assembly 41 includes a first transmission rod 411 and a second transmission rod 412, the first transmission rod 411 is tractively connected between crank 42 and the first cutting assembly 21, and crank 42 is adapted to drive the first transmission rod 411 to drive the first cutting assembly 21 and the second transmission rod 412 along the first direction of the circuit board cutting device 100 (i.e., up and down direction), crank 42 is located on the side of the first cutting assembly 21 away from the second cutting assembly 22, the transmission rod assembly 411 is located on the side of the first cutting assembly 21 away from the second cutting assembly 22, the transmission rod assembly 412 is located on the side of the first cutting assembly 21 away from the second cutting assembly 22, the transmission rod assembly 411 includes a first transmission rod 411 and a second Figure 3 (Up and down direction) movement.

[0059] When crank 42 rotates to drive one end of the first transmission rod 411 to move, the other end of the first transmission rod 411 drives the first cutting assembly 21 to move. Crank 42, first transmission rod 411 and first cutting assembly 21 together constitute a crank-slider mechanism. Since the length of the first transmission rod 411 does not change and crank 42 is located on the side of the first cutting assembly 21 away from the second cutting assembly 22, when crank 42 drives the first transmission rod 411 to move away from the second cutting assembly 22, the first transmission rod 411 drives the first cutting assembly 21 to move away from the second cutting assembly 22, thereby separating the first cutting assembly 21 from the second cutting assembly 22.

[0060] Conversely, when the crank 42 drives the first transmission rod 411 to move closer to the second cutting component 22, the first transmission rod 411 drives the first cutting component 21 to move closer to the second cutting component 22. This allows the first cutting component 21 and the second cutting component 22 to cut the circuit board 200 together, thereby achieving the technical effect of the drive mechanism 1 driving the cutting mechanism 2 to cut the circuit board 200 through the transmission mechanism 4. Compared with the prior art of using a cylinder to drive the cutter to cut the circuit board 200, when the crank-slider mechanism drives the cutting mechanism 2 to cut the circuit board 200, the impact of the first cutting component 21 on the circuit board 200 is smaller, which can improve the product quality of the circuit board 200.

[0061] Furthermore, the second transmission rod 412 is connected between the first cutting assembly 21 and the feeding assembly 31. The second transmission rod 412 can be used to transmit power to the feeding assembly 31, and when the second transmission rod 412 is driven by the first transmission rod 411, it drives the feeding assembly 31 along the second direction of the circuit board cutting equipment 100 (i.e., Figure 4 The first cutting component 21 moves along the first direction of the circuit board cutting equipment 100, while the feeding component 31 moves along the second direction of the circuit board cutting equipment 100. The first cutting component 21 and the feeding component 31 can move synchronously, thereby improving the coordination between the cutting component and the feeding component 31, and thus improving the processing efficiency of the circuit board cutting equipment 100.

[0062] See Figure 3 In some embodiments of this application, the cutting mechanism 2 further includes a first guide 23, which is positioned along a first direction of the circuit board cutting device 100 (i.e., Figure 3 The first cutting component 21 extends in the vertical direction and is guided and engaged with the first guide member 23. The first guide member 23 can be constructed as multiple parallel guide rods, which extend along a third direction (i.e., the vertical direction) of the circuit board cutting device 100. Figure 3The cutting components (in the left and right directions) are symmetrically arranged on both sides of the first cutting assembly 21. It should be noted that the first direction, second direction, and third direction of the circuit board cutting device 100 are perpendicular to each other. Through the guiding cooperation between the first cutting assembly 21 and the first guide member 23, the first cutting assembly 21 can move accurately along the first direction of the circuit board cutting device 100, which can avoid deviation in the movement of the cutting mechanism 2, improve the cutting accuracy of the cutting mechanism 2, help improve the product consistency of the circuit board 200, and thus improve the product quality of the circuit board 200.

[0063] See Figure 3 and Figure 4 In some embodiments of this application, the first cutting component 21 includes a first moving seat 211, a connector 212, and a first cutter 213. The first moving seat 211 is guided and cooperated with the first guide 23, so that the first moving seat 211 can move along the first direction of the circuit board cutting device 100. The connector 212 and the first cutter 213 are both disposed on the first moving seat 211. The first cutter 213 is disposed near the lower end of the first moving seat 211 and near the cutting gap. When the first moving seat 211 moves along the first direction of the circuit board cutting device 100, it can drive the first cutter 213 to move closer to or away from the circuit board 200. The first cutter 213 is suitable for cutting the circuit board 200 located in the cutting gap.

[0064] The connector 212 has a connecting portion 2121 and a pivot shaft 2122. The connecting portion 2121 is connected and engaged with the first moving seat 211 to fix the connector 212 to the first moving seat 211. When the first moving seat 211 moves, it drives the connector 212 to move. Both the first transmission rod 411 and the second transmission rod 412 are pivotally connected to the pivot shaft 2122. Figure 1 As shown, specifically, the connector 212 is located on the upper end of the first motion seat 211, the connecting part 2121 and the pivot shaft 2122 are fixedly connected, and the first transmission rod 411 and the second transmission rod 412 are both pivotally connected to the pivot shaft. The end of the first transmission rod 411 away from the crank 42 can drive the first motion seat 211 to move through the connector 212, and the end of the first transmission rod 411 away from the crank 42 can drive the second transmission rod 412 to move through the pivot shaft. In turn, the second transmission rod 412 can drive the feeding assembly 31 to move so that the feeding assembly transports the circuit board 200.

[0065] See Figure 4 , Figure 5 and Figure 7In some embodiments of this application, the second cutting assembly 22 includes a fixing base 221 and a second cutter 222. The second cutter 222 is disposed on the fixing base 221 and close to the cutting gap. The first cutter 213 and the second cutter 222 are along the second direction of the circuit board cutting device 100 (i.e., Figure 4 The first cutter 213 and the second cutter 222 are arranged in a front-to-back direction relative to each other. The shearing force generated between them can cut the circuit board 200 together. Furthermore, by staggering the first cutter 213 and the second cutter 222, the impact between them can be minimized, thus avoiding the impact on the service life of the first cutter 213 and the second cutter 222.

[0066] See Figure 1 and Figure 3 In some embodiments of this application, the feeding mechanism 3 further includes a second guide member 32, which extends along a second direction of the circuit board cutting device 100, and the feeding assembly 31 is guided and cooperates with the second guide member 32. For example, Figure 1 As shown, the second guide member 32 can be constructed as multiple guide rods. One end of the guide rod is fixedly connected to the mounting bracket 5, and the other end of the guide rod is constructed as the free end of the guide rod, which is provided with a stop block. Through the guiding cooperation between the feeding assembly 31 and the second guide member 32, the feeding assembly 31 can move accurately along the second direction of the circuit board cutting equipment 100. The contact position and separation position between the feeding assembly 31 and the circuit board 200 meet the preset requirements, which can ensure that the feeding assembly 31 transports the circuit board 200 to the preset cutting position. This allows the circuit board cutting equipment 100 to cut the circuit board 200 to meet the preset shape and size, further improving the product consistency of the circuit board 200 and enhancing the product quality of the circuit board 200.

[0067] The stop block can restrict the feeding assembly 31 from continuing to move away from the cutting mechanism 2, thereby preventing the feeding assembly 31 from disengaging from the second guide 32 and thus improving the operational reliability of the circuit board cutting equipment 100.

[0068] See Figure 1 , Figure 2 and Figure 8 In some embodiments of this application, the feeding assembly 31 includes a second moving seat 311, a pivot member 312, and a feeding member 313. The second moving seat 311 has a first pivot portion 3111, and the second moving seat 311 is guided and engaged with the second guide member 32. Specifically, the second moving seat 311 is sleeved on the outside of the second guide member 32. Figure 1In the illustrated embodiment, the second motion seat 311 is provided with a sliding hole suitable for the second guide member 32 to pass through. The size of the sliding hole can be set according to the size of the second guide member 32, so that the second motion seat 311 can slide along the second guide member 32, achieving the technical effect of guiding and cooperating between the feeding assembly 31 and the second guide member 32. The pivot member 312 is connected between the second motion seat 311 and the feeding member 313. The feeding member 313 is set close to the circuit board 200, which can shorten the interval distance between the feeding member 313 and the circuit board 200, making it easier for the feeding member 313 to cooperate with the circuit board 200 to transport the circuit board 200.

[0069] The pivot member 312 has a first rotating arm 3121, a second pivot part 3122, and a second rotating arm 3123. The second pivot part 3122 is connected between the first rotating arm 3121 and the second rotating arm 3123. The first rotating arm 3121 is pivotally connected to the end of the second transmission rod 412 away from the first cutting assembly 21. The second transmission rod 412 is adapted to drive the first rotating arm 3121 to move. The first pivot part 3111 is pivotally connected to the second pivot part 3122. When the first rotating arm 3121 is driven, it is adapted to drive the second motion seat 311 to move through the first pivot part 3111 and the second pivot part 3122. One of the first pivot portion 3111 and the second pivot portion 3122 has a pivot hole and the other has a pivot rod. In some specific embodiments of this application, the first pivot portion 3111 has a pivot hole and the second pivot portion 3122 has a pivot rod. The feeding member 313 is mounted on the second rotating arm 3123. When the pivot member 312 is driven by the second transmission rod 412, it is adapted to drive the feeding member 313 to rotate around the rotation axis of the second pivot portion 3122, wherein the rotation axis of the second pivot portion 3122 is the central axis of the pivot rod. The feeding member 313 is configured to extend into the feeding hole 201 of the circuit board 200 when the second moving seat 311 moves close to the cutting mechanism 2, and to extend out of the feeding hole 201 of the circuit board 200 when the second moving seat 311 moves away from the cutting mechanism 2. It should be noted that the feeding hole 201 is opened at the connection between two adjacent circuit boards 200 to be cut. The size of the feeding hole 201 can be set according to the size of the feeding member 313, so that the feeding member 313 can extend into the feeding hole 201. The feeding member 313 abuts against the inner wall of the feeding hole 201 to push the circuit board 200 toward the direction closer to the cutting mechanism 2.

[0070] Further, see Figure 3 and Figure 6The drive shaft 13 can be set on the upper side of the top wall of the mounting bracket 5, and the drive motor 11 can be set on the bottom wall of the mounting bracket 5. By setting the drive motor 11 close to the bottom of the circuit board cutting device 100, the center of gravity of the drive motor 11 on the circuit board cutting device 100 can be lowered, thereby making the drive motor 11 more stable when running on the circuit board cutting device 100. The drive motor 11, the transmission belt 12 and the drive shaft 13 work together to achieve the technical effect of the drive motor 11 outputting power over a long distance, so that the transmission mechanism 4 can receive the driving force.

[0071] Based on this, the implementation principle of the circuit board cutting device 100 described in this application embodiment is as follows:

[0072] When the circuit board cutting equipment 100 processes and cuts the circuit board 200, a cutting mechanism 2 and a feeding mechanism 3 are set on the mounting bracket 5. Under the drive of the drive mechanism 1, the transmission mechanism 4 drives the cutting mechanism 2 and the feeding mechanism 3 to move. When the transmission rod group 41 of the transmission mechanism 4 moves from the first position to the second position, it drives the first cutting component 21 to move closer to the second cutting component 22 and drives the feeding component 31 to move away from the cutting mechanism 2. The first cutting component 21 and the second cutting component 22 cut the circuit board 200 together and the feeding component 31 is separated from the circuit board 200.

[0073] Furthermore, when the transmission rod assembly 41 moves from the second position to the first position, it drives the first cutting component 21 away from the second cutting component 22 and drives the feeding component 31 closer to the cutting mechanism 2. At this time, the first cutting component 21 and the second cutting component 22 separate and form a cutting gap, and the feeding component 31 transports the circuit board 200 to the preset cutting position. By working together with the cutting mechanism 2 and the feeding mechanism 3 to cut the circuit board 200, the coordination between different mechanisms can be improved, the smoothness of the connection between the mechanisms can be ensured, and thus the cutting efficiency of the circuit board 200 can be improved.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
