Description

Technical Field

[0001] This application relates to the field of circuit board processing, and more specifically, to a circuit board cutting apparatus. Background Technology

[0002] PCBA boards are core components of various electronic products. They integrate multiple functions such as circuit connection, component mounting, and signal transmission. PCBA boards refer to circuit board assemblies in electronic products that connect electronic components (such as resistors, capacitors, inductors, transistors, integrated circuits, etc.) according to a predetermined circuit diagram through printed circuit board (PCB) technology to form a circuit board assembly with specific functions. It is not only responsible for signal transmission and processing, but also connects and communicates with external devices through interfaces on the board.

[0003] Modern electronic devices often employ modular design to better achieve functional zoning and maintenance. By cutting, circuit areas with different functions can be separated into independent modules. At the same time, in order to optimize layout and wiring and save production costs during PCB design, multiple functional modules may be designed on the same board. However, during production or maintenance, in order to facilitate the replacement or upgrading of specific modules, they need to be cut off from the whole board.

[0004] PCBA boards are typically cut using specialized cutting equipment. The cutting blade is driven by a rotating shaft. Over time, the shaft's rotational efficiency decreases, requiring regular lubrication of the shaft's outer wall to ensure proper operation. This process increases the number of steps required for operation, thus reducing the efficiency of PCBA board cutting. Summary of the Invention

[0005] This application provides a circuit board cutting device to at least solve the problem of complex manual lubrication operation in related technologies.

[0006] According to one embodiment of this application, a circuit board cutting device is provided, comprising: a cutting table having a first mounting cavity and a lubrication cavity for storing lubricant; a cutting blade having a rotating shaft rotatably disposed within the first mounting cavity and located below the lubrication cavity; a first magnetic element having a lubrication port at the bottom of the lubrication cavity, the first magnetic element being movably disposed at the lubrication port and having a closed position that blocks the lubrication port and an open position that avoids the lubrication port; and a second magnetic element connected to the rotating shaft and rotating synchronously, the second magnetic element being able to magnetically cooperate with the first magnetic element and drive the first magnetic element to switch between the closed position and the open position.

[0007] In one exemplary embodiment, the magnetic poles of the first magnetic element and the second magnetic element are opposite, and the second magnetic element can drive the first magnetic element to move upward to open the lubrication port.

[0008] In one exemplary embodiment, the circuit board cutting apparatus further includes an oiling component connected to the cutting table and located between the inner wall of the first mounting cavity and the rotating shaft.

[0009] In one exemplary embodiment, at least a portion of the oil brush is located on the side of the first magnetic element facing the shaft.

[0010] In one exemplary embodiment, the circuit board cutting apparatus further includes an agitator connected to a first magnetic element and disposed within a lubrication cavity. When the first magnetic element moves, it drives the agitator to move to agitate the lubricant within the lubrication cavity.

[0011] In one exemplary embodiment, the agitator has one or more through holes, and when there are multiple through holes, the through holes are arranged at intervals along the surface of the agitator.

[0012] In one exemplary embodiment, the agitator has a transmission end, and the circuit board cutting device further includes: a transmission member that is driven by the transmission end, the transmission member moving under the drive of the transmission end; and a prompting component that is triggerably engaged with the transmission member. When the remaining amount of lubricant in the lubrication cavity is lower than a predetermined amount, the transmission member moves under the drive of the transmission end and triggers the prompting component, which generates a prompting signal.

[0013] In one exemplary embodiment, the transmission end is a magnetic end, the transmission component is a magnetic part, and the cutting table also has a second mounting cavity, which is separated from the first mounting cavity. The transmission component and the prompting component are both disposed in the second mounting cavity.

[0014] In one exemplary embodiment, the circuit board cutting device further includes: a fixing ring, which is sleeved on the outer peripheral side of the end of the rotating shaft and connected to the cutting table; and a cleaning member, which is disposed between the fixing ring and the peripheral side of the rotating shaft and blocks impurities from entering the gap between the rotating shaft and the inner wall of the first mounting cavity.

[0015] In one exemplary embodiment, the magnetic poles of the first magnetic element and the second magnetic element are opposite, and the second magnetic element can drive the first magnetic element to move upward to open the lubrication port; the circumferential side of the rotating shaft has a receiving groove, the second magnetic element is embedded in the receiving groove, and the outer surface of the second magnetic element is flush with the circumferential side of the rotating shaft; there are one or more second magnetic elements, and when there are multiple second magnetic elements, at least some of the second magnetic elements are arranged along the axial direction of the rotating shaft; the circuit board cutting device also includes an oiling component, which is located between the inner wall of the first mounting cavity and the rotating shaft, and when the rotating shaft rotates, the oiling component spreads the lubricant evenly on the surface of the rotating shaft; the circuit board cutting device also includes an agitator, which agitates... The moving part is connected to the connecting section of the first magnetic part and is disposed in the lubrication cavity. When the first magnetic part moves, it drives the stirring part to move to stir the lubricant in the lubrication cavity. The stirring part has a magnetic end. The circuit board cutting device also includes a transmission part with magnetic cooperation, and the magnetic end is the same as the magnetic pole of the transmission part. The cutting table also has a second mounting cavity, which is separated from the first mounting cavity. The circuit board cutting device also includes a prompting component. Both the transmission part and the prompting component are disposed in the second mounting cavity. When the remaining amount of lubricant in the lubrication cavity is lower than a predetermined amount, the transmission part moves under the drive of the magnetic end and triggers the prompting component, which generates a prompting signal.

[0016] By applying the technical solution of this invention, a lubrication cavity is provided on the cutting table, along with a first magnetic component and a second magnetic component. The first magnetic component controls the lubrication port of the lubrication cavity. When the first magnetic component blocks the lubrication port, it closes the lubrication port, preventing communication between the lubrication cavity and the first mounting cavity. This prevents the lubricant in the lubrication cavity from entering the first mounting cavity and thus prevents leakage. The second magnetic component controls the first magnetic component. Since the second magnetic component is mounted on a rotating shaft, when the device is working normally, the rotating shaft rotates, causing the second magnetic component to switch between positions close to and away from the first magnetic component. When the second magnetic component approaches the first magnetic component, it moves the first magnetic component, causing it to switch to the open position. At this time, the lubrication port is opened, allowing the lubricating oil in the lubrication cavity to flow through the lubrication port onto the rotating shaft below, thus lubricating the shaft as it rotates. As the shaft rotates, the lubrication port repeatedly switches between open and closed states, allowing lubricant to intermittently flow from the lubrication chamber onto the shaft. This continuous lubrication during operation ensures smooth movement of the cutting blade. This design achieves lubrication as the shaft drives the cutting blade, eliminating the need for periodic lubrication of the shaft's outer wall. This reduces the number of steps required for using the circuit board cutting device, thereby improving efficiency. Attached Figure Description

[0027] To address the problem of complex manual lubrication operations in cutting devices in related technologies, this application provides a circuit board cutting device.

[0028] Example 1

[0029] like Figures 1 to 5The circuit board cutting device shown includes a cutting table 10, a cutting blade 20, a first magnetic element 30, and a second magnetic element 40. The cutting table 10 has a first mounting cavity 11 and a lubrication cavity 12 for storing lubricant. The rotating shaft 21 of the cutting blade 20 is rotatably disposed in the first mounting cavity 11 and located below the lubrication cavity 12. The bottom of the lubrication cavity 12 has a lubrication port. The first magnetic element 30 is movably disposed at the lubrication port and has a closed position that blocks the lubrication port and an open position that avoids the lubrication port. The second magnetic element 40 is connected to the rotating shaft 21 and rotates synchronously. The second magnetic element 40 can magnetically cooperate with the first magnetic element 30 and drive the first magnetic element 30 to switch between the closed position and the open position.

[0030] In this embodiment, a lubrication cavity 12 is provided on the cutting table 10, along with a first magnetic element 30 and a second magnetic element 40. The first magnetic element 30 controls the lubrication opening of the lubrication cavity 12. When the first magnetic element 30 blocks the lubrication opening, it closes the opening, preventing communication between the lubrication cavity 12 and the first mounting cavity 11. This prevents lubricant from entering the first mounting cavity 11 and thus avoids leakage. The second magnetic element 40 controls the first magnetic element 30. The device is mounted on the rotating shaft 21. When the device is operating normally, the rotating shaft 21 rotates, causing the second magnetic element 40 to switch between positions close to and away from the first magnetic element 30. When the second magnetic element 40 approaches the first magnetic element 30, it moves the first magnetic element 30, causing the second magnetic element 40 to switch to the open position. At this time, the lubrication port is opened, and the lubricating oil in the lubrication chamber 12 can flow through the lubrication port to the rotating shaft 21 below, lubricating the rotating shaft 21 as it rotates. As the rotating shaft 21 rotates, the lubrication port repeatedly switches between open and closed states, causing lubricant to intermittently flow from the lubrication chamber 12 to the rotating shaft 21, thus continuously lubricating the rotating shaft 21 during operation and ensuring the smooth movement of the cutting blade 20. The above-mentioned setup allows for lubrication when the rotating shaft 21 drives the cutting blade 20, eliminating the need for operators to periodically lubricate the outer wall of the rotating shaft 21. This reduces the number of steps required for operators to use the circuit board cutting device, thereby improving the efficiency of operators in cutting circuit boards using the circuit board cutting device.

[0031] In this embodiment, the first magnetic component 30 moves upward when it is opened. Based on this, the magnetic poles of the first magnetic component 30 and the second magnetic component 40 are opposite, so that when the second magnetic component 40 is facing the first magnetic component 30, it can drive the first magnetic component 30 to move upward to open the lubrication port.

[0032] The circuit board cutting device of this embodiment also includes a motor 110 and other driving components. The motor 110 can be set at the end of the rotating shaft 21 or other positions, and is directly or indirectly connected to the rotating shaft 21 for transmission, so that the cutting blade 20 rotates as a whole under the drive of the motor 110 to achieve the effect of cutting the circuit board.

[0033] like Figure 3 As shown, the circuit board cutting device of this embodiment also includes an elastic element 120. The elastic element 120 can be a spring or other component. The elastic element 120 is connected to the first magnetic element 30, thereby providing the first magnetic element 30 with a spring force to move towards the closed position. Thus, when the second magnetic element 40 leaves the magnetic force range of the first magnetic element 30, the first magnetic element 30 can automatically switch to the closed position under the action of the elastic element 120.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, the circumferential side of the rotating shaft 21 has a receiving groove, and the second magnetic component 40 is embedded in the receiving groove. The outer surface of the second magnetic component 40 is flush with the circumferential side of the rotating shaft 21. In this way, the embedded setting ensures that the second magnetic component 40 does not protrude from the circumferential side of the rotating shaft 21, so that the circumferential side of the rotating shaft 21 remains smooth as a whole, avoiding interference or collision with other components due to protrusion, and ensuring the safety of use.

[0035] Optionally, there may be one or more second magnetic elements 40. When there are multiple second magnetic elements 40, at least some of them are arranged along the axial direction of the rotating shaft 21. In this embodiment, two second magnetic elements 40 are provided. Both second magnetic elements 40 are embedded in the receiving groove. The two second magnetic elements 40 are circumferentially symmetrically arranged on both sides of the rotating shaft 21, so that the lubrication port can be opened once every 180 degrees of rotation of the rotating shaft 21 to replenish and lubricate the lubricant.

[0036] In this embodiment, lubricating oil is used as the lubricant, but other types of lubricants can also be used. In this embodiment, an inlet hole is provided at the top of the lubrication chamber 12 to facilitate the addition of lubricant into the lubrication chamber 12.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the circuit board cutting device further includes an oiling component 50. The oiling component 50 can be in the form of a brush or similar structure. The oiling component 50 is connected to the cutting table 10 and is located between the inner wall of the first mounting cavity 11 and the rotating shaft 21. In this way, when the rotating shaft 21 rotates, the lubricating oil that drips onto the circumferential side of the rotating shaft 21 can be evenly applied to the entire circumferential side of the rotating shaft 21 under the action of the oiling component 50. By rotating and brushing the oiling component 50, the lubricant on the surface of the rotating shaft 21 is evenly spread, thereby improving the lubrication effect of the lubricant on the outer wall of the rotating shaft.

[0038] Since the lubricant falls onto the rotating shaft 21 through the lubrication port, in this embodiment, it is preferable that at least part of the oil brush 50 is located on the side of the first magnetic element 30 facing the rotating shaft 21. The oil brush 50 can cover the entire axial length of the rotating shaft 21 as needed, or it can only cover a part of the axial length of the rotating shaft 21. The specific details can be adjusted as needed. However, the oil brush 50 should be set at the lubrication port as much as possible to ensure that the falling lubricant can be evenly applied as soon as possible under the action of the oil brush 50.

[0039] like Figure 4 As shown, in this embodiment, the circuit board cutting device further includes an agitator 60, which is connected to the first magnetic component 30 and disposed in the lubrication cavity 12. When the first magnetic component 30 moves, it drives the agitator 60 to move to agitate the lubricant in the lubrication cavity 12.

[0040] Specifically, in this embodiment, a connecting section 31 is provided on the side of the first magnetic component 30 facing the interior of the lubrication cavity 12. The connecting section 31 can be a non-magnetic part. The stirring component 60 is a plate-shaped component, which is sleeved on the outside of the connecting section 31 and can move along the moving direction of the first magnetic component 30 under the drive of the connecting section 31. In this way, when the first magnetic component 30 moves under the drive of the second magnetic component 40, the first magnetic component 30 can also drive the stirring component 60 to move, so that the stirring component 60 can stir the lubricant in the lubrication cavity 12, thereby increasing the flow effect of the lubricant at the bottom of the lubrication cavity 12, avoiding the precipitation phenomenon, and thus improving the lubrication effect of the lubricant on the rotating shaft 21.

[0041] Preferably, the agitator 60 has one or more through holes. When there are multiple through holes, they are arranged at intervals along the surface of the agitator 60. The through holes improve the pushing effect on the lubricating oil, thereby improving the agitation effect. Of course, the agitator 60 can also adopt other shapes besides a plate-like structure with through holes, such as a conical shape.

[0042] In this embodiment, the agitator 60, in addition to agitating the lubricant to improve the lubrication effect, also monitors the remaining amount of lubricant. Specifically, the agitator 60 has a transmission end, and the circuit board cutting device also includes a transmission component 70 and a prompting component 80. The transmission component 70 is driven by the transmission end and moves under its drive. The prompting component 80 is triggered to engage with the transmission component 70. When the remaining amount of lubricant in the lubrication cavity 12 is lower than a predetermined amount, the transmission component 70 moves under the drive of the transmission end and triggers the prompting component 80. The prompting component 80 generates a prompt signal, which can be an audible or visual signal, thereby prompting personnel to perform an inspection operation.

[0043] To prevent the lubricant from affecting electrically connected components such as the indicator component 80, the cutting table 10 in this embodiment also has a second mounting cavity 13, which is separated from the first mounting cavity 11. Both the transmission component 70 and the indicator component 80 are disposed within the second mounting cavity 13, thus separating them from the lubricant and preventing their influence. Simultaneously, to ensure proper transmission between the transmission end and the transmission component 70, this embodiment uses a magnetic end, and the transmission component 70 is a magnetic component. This allows for magnetic engagement between the transmission end and the transmission component 70, with the magnetic end and transmission component 70 sharing the same magnetic poles. This allows the magnetic end to move, attracting the transmission component 70 and triggering the indicator component 80.

[0044] In this embodiment, the triggered end of the prompting component 80 is located at the top of the second mounting cavity 13, while the triggering end is located on the upper surface of the transmission component 70. When the transmission component 70 moves upward to its designated position, the triggering end triggers the triggered end, thereby triggering the prompting component 80. When the remaining amount of lubricant is higher than a predetermined amount, when the first magnetic component 30 drives the agitator 60 to move upward through the connecting section 31, the agitator 60 is resisted by the lubricant, resulting in a small upward displacement. At this time, the agitator 60 cannot drive the transmission component 70 to the position to trigger the prompting component 80, thus failing to trigger the prompting component 80. However, when the lubricant in the lubrication cavity 12 is depleted and falls below the predetermined amount, the agitator 60 loses the liquid resistance of the lubricant, allowing it to drive the transmission component 70 to move upward a greater distance. This enables the transmission component 70 to trigger the prompting component 80 for an alarm, making it easier for staff to know the usage status after the lubricant has been used up, thus facilitating the addition of lubricant.

[0045] like Figure 5 As shown, in this embodiment, the circuit board cutting device further includes a fixing ring 90 and a cleaning component 100. The fixing ring 90 is sleeved on the outer periphery of the end of the rotating shaft 21 and connected to the cutting table 10. The cleaning component 100 can be a component such as a brush. The cleaning component 100 is disposed between the fixing ring 90 and the periphery of the rotating shaft 21. In this way, when the rotating shaft 21 rotates, the cleaning component 100 contacts the rotating shaft 21 and can rotate and clean the debris and other impurities cut by the cutting blade 20, so as to prevent impurities from adhering to the outer wall of the rotating shaft 21 or even entering the gap between the rotating shaft 21 and the inner wall of the first mounting cavity 11, which would cause blockage and jamming, thereby improving the rotation efficiency of the rotating shaft 21.

[0046] like Figure 1As shown, the cutting blade 20 of this embodiment includes a disc-shaped blade body and a rotating shaft 21 disposed at the center of the blade body end face. A rotating shaft 21 is also disposed at the center of each of the two opposite end faces of the blade body, allowing the blade body to rotate smoothly with the support of the rotating shafts 21 on both sides. Based on this, the cutting table 10 of this embodiment includes a central mounting cavity 14 and two first mounting cavities 11. The two first mounting cavities 11 are located on both sides of the central mounting cavity 14 and are interconnected. The central mounting cavity 14 is used to accommodate the blade body, and the top of the blade body can extend from the upper opening of the central mounting cavity 14 to achieve the cutting function of the circuit board. The rotating shafts 21 on both sides of the blade body are located in the two first mounting cavities 11. Each rotating shaft 21 is provided with cooperating first magnetic components 30, second magnetic components 40, etc., so that both sides of the rotating shaft 21 can receive automatic and continuous lubrication with lubricant.

[0047] Example 2

[0048] The circuit board cutting device of this embodiment includes a cutting table 10, a cutting blade 20, a first magnetic component 30, and a second magnetic component 40. The cutting table 10 has a first mounting cavity 11 and a lubrication cavity 12 for storing lubricant. The rotating shaft 21 of the cutting blade 20 is rotatably disposed in the first mounting cavity 11 and located below the lubrication cavity 12. The bottom of the lubrication cavity 12 has a lubrication port. The first magnetic component 30 is movably disposed at the lubrication port and has a closed position that blocks the lubrication port and an open position that avoids the lubrication port. The second magnetic component 40 is connected to the rotating shaft 21 and rotates synchronously. The second magnetic component 40 can magnetically cooperate with the first magnetic component 30 and drive the first magnetic component 30 to switch between the closed position and the open position.

[0049] In this embodiment, a lubrication cavity 12 is provided on the cutting table 10, along with a first magnetic element 30 and a second magnetic element 40. The first magnetic element 30 controls the lubrication opening of the lubrication cavity 12. When the first magnetic element 30 blocks the lubrication opening, it closes the opening, preventing communication between the lubrication cavity 12 and the first mounting cavity 11. This prevents lubricant from entering the first mounting cavity 11 and thus avoids leakage. The second magnetic element 40 controls the first magnetic element 30. The device is mounted on the rotating shaft 21. When the device is operating normally, the rotating shaft 21 rotates, causing the second magnetic element 40 to switch between positions close to and away from the first magnetic element 30. When the second magnetic element 40 approaches the first magnetic element 30, it moves the first magnetic element 30, causing the second magnetic element 40 to switch to the open position. At this time, the lubrication port is opened, and the lubricating oil in the lubrication chamber 12 can flow through the lubrication port to the rotating shaft 21 below, lubricating the rotating shaft 21 as it rotates. As the rotating shaft 21 rotates, the lubrication port repeatedly switches between open and closed states, causing lubricant to intermittently flow from the lubrication chamber 12 to the rotating shaft 21, thus continuously lubricating the rotating shaft 21 during operation and ensuring the smooth movement of the cutting blade 20. The above-mentioned setup allows for lubrication when the rotating shaft 21 drives the cutting blade 20, eliminating the need for operators to periodically lubricate the outer wall of the rotating shaft 21. This reduces the number of steps required for operators to use the circuit board cutting device, thereby improving the efficiency of operators in cutting circuit boards using the circuit board cutting device.

[0050] In this embodiment, the first magnetic component 30 moves downwards from the closed position to the open position. This allows the first magnetic component 30 to avoid obstructing the lubrication port when it reaches the open position. However, unlike Embodiment 1, the above-mentioned arrangement in this embodiment requires consideration of interference between the first magnetic component 30 and other components during its downward movement. It is essential to ensure that the first magnetic component 30 moves downwards, i.e., towards the rotating shaft 21, without interfering with other components, thereby guaranteeing the stability and safety of the overall operation.

[0051] Based on the above configuration, this embodiment adopts the form that the first magnetic element 30 and the second magnetic element 40 have the same magnetic poles. When the second magnetic element 40 faces the first magnetic element 30, it can drive the first magnetic element 30 to move downward, thereby opening the lubrication port.

[0052] In this embodiment, the circuit board cutting device further includes an oiling component 50. The oiling component 50 can be in the form of a brush or similar structure. The oiling component 50 is connected to the cutting table 10 and is located between the inner wall of the first mounting cavity 11 and the rotating shaft 21. Thus, when the rotating shaft 21 rotates, the lubricating oil that drips onto the circumferential surface of the rotating shaft 21 can be evenly spread across the entire circumferential surface of the rotating shaft 21 under the action of the oiling component 50. The rotating brushing motion of the oiling component 50 further evenly spreads the lubricant on the surface of the rotating shaft 21, improving the lubricant's effect on the outer wall of the rotating shaft. In this embodiment, lubricating oil is used as the lubricant, but other types of lubricants can also be used.

[0053] In this embodiment, the circuit board cutting device further includes an agitator 60, which is connected to the first magnetic element 30 and disposed in the lubrication cavity 12. When the first magnetic element 30 moves, it drives the agitator 60 to move to agitate the lubricant in the lubrication cavity 12.

[0054] Specifically, in this embodiment, a connecting section 31 is provided on the side of the first magnetic component 30 facing the interior of the lubrication cavity 12. The connecting section 31 can be a non-magnetic part. The stirring component 60 is a plate-shaped component, which is sleeved on the outside of the connecting section 31 and can move along the moving direction of the first magnetic component 30 under the drive of the connecting section 31. In this way, when the first magnetic component 30 moves under the drive of the second magnetic component 40, the first magnetic component 30 can also drive the stirring component 60 to move, so that the stirring component 60 can stir the lubricant in the lubrication cavity 12, thereby increasing the flow effect of the lubricant at the bottom of the lubrication cavity 12, avoiding the precipitation phenomenon, and thus improving the lubrication effect of the lubricant on the rotating shaft 21.

[0055] In this embodiment, the agitator 60, in addition to agitating the lubricant to improve the lubrication effect, also monitors the remaining amount of lubricant. Specifically, the agitator 60 has a transmission end, and the circuit board cutting device also includes a transmission component 70 and a prompting component 80. The transmission component 70 is driven by the transmission end and moves under its drive. The prompting component 80 is triggered to engage with the transmission component 70. When the remaining amount of lubricant in the lubrication cavity 12 is lower than a predetermined amount, the transmission component 70 moves under the drive of the transmission end and triggers the prompting component 80. The prompting component 80 generates a prompt signal, which can be an audible or visual signal, thereby prompting personnel to perform an inspection operation.

[0056] To prevent the lubricant from affecting electrically connected components such as the indicator component 80, the cutting table 10 in this embodiment also has a second mounting cavity 13, which is separated from the first mounting cavity 11. Both the transmission component 70 and the indicator component 80 are disposed within the second mounting cavity 13, thus separating them from the lubricant and preventing their influence. Simultaneously, to ensure proper transmission between the transmission end and the transmission component 70, this embodiment uses a magnetic end, and the transmission component 70 is a magnetic component. This allows for magnetic engagement between the transmission end and the transmission component 70, with the magnetic end and transmission component 70 sharing the same magnetic poles. This allows the magnetic end to move, attracting the transmission component 70 and triggering the indicator component 80.

[0057] In this embodiment, the triggered end of the prompting component 80 is located at the bottom of the second mounting cavity 13, while the triggering end is located on the lower surface of the transmission component 70. When the transmission component 70 moves downward to its designated position, the triggering end triggers the triggered end, thereby triggering the prompting component 80. When the remaining amount of lubricant is higher than a predetermined amount, when the first magnetic component 30 drives the agitator 60 downward through the connecting section 31, the agitator 60 is resisted by the lubricant, resulting in a small downward displacement. At this time, the agitator 60 cannot drive the transmission component 70 downward to the position to trigger the prompting component 80, thus failing to trigger the prompting component 80. However, when the lubricant in the lubrication cavity 12 is depleted and falls below the predetermined amount, the agitator 60 loses the liquid resistance of the lubricant, allowing it to drive the transmission component 70 downward a greater distance. This enables the transmission component 70 to trigger the prompting component 80 for an alarm, making it easier for staff to know the usage status after the lubricant has been used up, thus facilitating the addition of lubricant.

[0058] In this embodiment, the circuit board cutting device further includes a fixing ring 90 and a cleaning component 100. The fixing ring 90 is sleeved on the outer periphery of the end of the rotating shaft 21 and connected to the cutting table 10. The cleaning component 100 can be a component such as a brush. The cleaning component 100 is disposed between the fixing ring 90 and the peripheral side of the rotating shaft 21. In this way, when the rotating shaft 21 rotates, the cleaning component 100 contacts the rotating shaft 21 and can rotate and clean the debris and other impurities cut by the cutting blade 20, so as to prevent impurities from adhering to the outer wall of the rotating shaft 21 or even entering the gap between the rotating shaft 21 and the inner wall of the first mounting cavity 11, which would cause blockage and jamming, thereby improving the rotation efficiency of the rotating shaft 21.

[0059] It should be noted that "multiple" in the above embodiments refers to at least two.

[0060] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0061] 1. This solved the problem of complex manual lubrication operation for cutting devices in related technologies;

[0062] 2. The rotating shaft is lubricated when it drives the cutting blade. There is no need for the operator to lubricate the outer wall of the rotating shaft regularly. This reduces the number of operation steps for the operator when using the circuit board cutting device, thereby improving the work efficiency of the operator when using the circuit board cutting device to cut circuit boards.

[0063] 3. The rotating brushing mechanism spreads the lubricant evenly on the surface of the shaft, improving the lubricant's effect on the outer wall of the shaft.

[0064] 4. The agitator can agitate the lubricant in the lubrication chamber, thereby increasing the flow of the lubricant at the bottom of the lubrication chamber, preventing sedimentation, and thus improving the lubrication effect of the lubricant on the shaft.

[0065] 5. The agitator, in conjunction with the transmission component and the indicator assembly, causes the remaining amount of lubricant in the lubrication chamber to fall below a predetermined level. In this case, the indicator assembly generates an indicator signal to prompt personnel to perform an inspection.

[0066] 6. The cleaning component can rotate and clean the debris and other impurities cut by the cutting blade, preventing impurities from adhering to the outer wall of the rotating shaft or even entering the gap between the rotating shaft and the inner wall of the first mounting cavity, thus avoiding blockage and jamming, thereby improving the rotation efficiency of the rotating shaft.
