[0003] Current electronic devices often adopt modular design to better achieve functional partitioning and maintenance. Circuit areas with different functions can be separated by cutting to form independent modules. At the same time, in the PCB design process, in order to optimize layout and wiring and save production costs, multiple functional modules may be designed on the same board. However, during the production or maintenance process, in order to facilitate the replacement or upgrade of specific modules, they need to be cut from the entire board.
[0004] PCBA boards are usually cut with a dedicated cutting device, whose cutting blade is driven by a rotating shaft. When the rotating shaft is used for a long time, its rotation efficiency will decrease. At this time, the staff needs to lubricate the outer wall of the rotating shaft regularly to ensure the normal use of the cutting device. This process correspondingly increases the number of operating steps for the staff to use the cutting device, thereby reducing the work efficiency of the staff using the cutting device to cut PCBA boards.

[0027] In order to solve the problem of complicated manual lubrication operation of the cutting device in the related art, an embodiment of the present application provides a circuit board cutting device.
[0028] Embodiment 1
[0029] like Figures 1 to 5A circuit board cutting device shown in the figure includes a cutting table 10, a cutting knife 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 knife 20 is rotatably arranged in the first mounting cavity 11 and is located below the lubrication cavity 12; the bottom of the lubrication cavity 12 has a lubrication port, the first magnetic component 30 is movably arranged at the lubrication port, and has a closed position for shielding the lubrication port and an open position for avoiding the lubrication port; the second magnetic component 40 is connected to the rotating shaft 21 and rotates synchronously, the second magnetic component 40 can cooperate with the first magnetic component 30 magnetically, and drive the first magnetic component 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, and a first magnetic member 30 and a second magnetic member 40 are provided, wherein the first magnetic member 30 can control the lubrication port of the lubrication cavity 12. When the first magnetic member 30 blocks the lubrication port, the first magnetic member 30 closes the lubrication port so that the lubrication cavity 12 is not connected to the first installation cavity 11, and the lubricant in the lubrication cavity 12 cannot enter the first installation cavity 11, so it will not leak out, and the second magnetic member 40 plays a role in controlling the first magnetic member 30. It is arranged on the rotating shaft 21, so when the device works normally, the rotating shaft 21 rotates, and the rotation of the rotating shaft 21 drives the second magnetic member 40 to switch between positions close to and away from the first magnetic member 30. When the second magnetic member 40 approaches the first magnetic member 30, the second magnetic member 40 drives the first magnetic member 30 to move, so that the second magnetic member 40 switches to the open position. At this time, the lubrication port is opened, and the lubricating oil in the lubrication cavity 12 can flow to the rotating shaft 21 below through the lubrication port, and lubricate the rotating shaft 21 as the rotating shaft 21 rotates. As the rotating shaft 21 rotates, the lubrication port switches back and forth between the open and closed states, so that the lubricant intermittently flows from the lubrication cavity 12 to the rotating shaft 21, so that the rotating shaft 21 is continuously lubricated during the working process, ensuring that the cutting knife 20 can move smoothly. The above-mentioned setting method realizes lubrication when the rotating shaft 21 drives the cutting knife 20 to work, and there is no need for the staff to regularly lubricate the outer wall of the rotating shaft 21, thereby reducing the operating steps for the staff to use the circuit board cutting device, thereby improving the work efficiency of the staff in using the circuit board cutting device to cut the circuit board.
[0031] In this embodiment, the first magnetic component 30 moves upward when opened. Based on this, the magnetic poles of the first magnetic component 30 and the second magnetic component 40 of this embodiment are opposite, so that when the second magnetic component 40 is directed toward 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 driving components such as a motor 110. The motor 110 can be set at a position such as the end of the rotating shaft 21, and is directly or indirectly connected to the rotating shaft 21, so that the cutting knife 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 further includes an elastic member 120, which can be a spring or other component, and is connected to the first magnetic member 30, thereby providing an elastic force for the first magnetic member 30 to move to the closed position. Therefore, when the second magnetic member 40 leaves the magnetic force range of the first magnetic member 30, the first magnetic member 30 can automatically switch to the closed position under the action of the elastic member 120.
[0034] like Figure 3 and Figure 4 As shown, in the present embodiment, the circumferential side surface of the rotating shaft 21 has a receiving groove, the second magnetic component 40 is embedded in the receiving groove, and the outer surface of the second magnetic component 40 is flush with the circumferential side surface of the rotating shaft 21. In this way, the embedded setting method is adopted so that the second magnetic component 40 will not protrude from the circumferential side surface of the rotating shaft 21, so that the circumferential side surface of the rotating shaft 21 remains smooth as a whole, avoiding protrusions and interference and collision with other components, thereby ensuring safety in use.
[0035] Optionally, the second magnetic member 40 is one or more, and when the second magnetic member 40 is more than one, at least part of the second magnetic member 40 is arranged along the axial direction of the rotating shaft 21. In this embodiment, two second magnetic members 40 are provided, and the two second magnetic members 40 are both embedded in the receiving groove, and the two second magnetic members 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 achieve lubricant replenishment and lubrication.
[0036] The lubricant of this embodiment is lubricating oil, and other types of lubricants can also be used. In this embodiment, a feed hole is provided at the top of the lubricating cavity 12, so as to facilitate adding lubricant into the lubricating cavity 12.
[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the circuit board cutting device further includes an oil brush 50, which can be a brush or other structural form, connected to the cutting table 10, and 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 dripping on the peripheral side of the rotating shaft 21 can be evenly applied to the entire peripheral side of the rotating shaft 21 under the action of the oil brush 50, and the lubricant on the surface of the rotating shaft 21 is evenly applied by the rotation and brushing of the oil brush 50, thereby improving the 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, preferably at least part of the oil brush member 50 is located on the side of the first magnetic member 30 facing the rotating shaft 21. The oil brush member 50 can cover the entire axial length of the rotating shaft 21 as needed, or can only cover a part of the axial length of the rotating shaft 21. The specific length can be adjusted as needed, but the oil brush member 50 is set at the lubrication port as much as possible to ensure that the fallen lubricant can be evenly spread by the oil brush member 50 as soon as possible.
[0039] like Figure 4 As shown, in this embodiment, the circuit board cutting device also includes a stirring member 60, which is connected to the first magnetic member 30 and is disposed in the lubrication chamber 12. When the first magnetic member 30 moves, the stirring member 60 is driven to move to stir the lubricant in the lubrication chamber 12.
[0040] Specifically, in this embodiment, a connecting section 31 is provided on the side of the first magnetic part 30 facing the inside of the lubrication chamber 12. The connecting section 31 can be a non-magnetic part. The agitator 60 is a plate-shaped part, which is sleeved on the outside of the connecting section 31 and can move along the moving direction of the first magnetic part 30 under the drive of the connecting section 31. In this way, when the first magnetic part 30 moves under the drive of the second magnetic part 40, the first magnetic part 30 can also drive the agitator 60 to move, so that the agitator 60 can stir the lubricant in the lubrication chamber 12, thereby increasing the flow effect of the lubricant at the bottom of the lubrication chamber 12, avoiding its sedimentation, and thus improving the lubrication effect of the lubricant on the rotating shaft 21.
[0041] Preferably, the agitator 60 has a through hole, which may be one or more through holes. When there are more than one through holes, the through holes are arranged at intervals along the surface of the agitator 60. The provision of the through holes can improve the effect of pushing the lubricating oil, thereby improving the agitation effect. Of course, in addition to the structural form of a plate-like member plus a through hole, the agitator 60 may also be in other shapes, such as a cone.
[0042] In this embodiment, the stirring member 60 not only stirs the lubricant to improve the lubrication effect, but also monitors the remaining amount of the lubricant. Specifically, the stirring member 60 has a transmission end, and the circuit board cutting device also includes a transmission member 70 and a prompt component 80. The transmission member 70 is in transmission cooperation with the transmission end, and the transmission member 70 moves under the drive of the transmission end; the prompt component 80 and the transmission member 70 can be triggered to cooperate. When the remaining amount of lubricant in the lubrication cavity 12 is lower than a predetermined amount, the transmission member 70 moves under the drive of the transmission end and triggers the prompt component 80. The prompt component 80 generates a prompt signal, which can be an audio-visual signal, etc., so as to prompt personnel to perform inspection operations.
[0043] In order to prevent the lubricant from affecting the electrically charged components such as the prompt component 80, the cutting table 10 of this embodiment also has a second installation cavity 13, and the second installation cavity 13 is separated from the first installation cavity 11, and the transmission component 70 and the prompt component 80 are both arranged in the second installation cavity 13, so that the transmission component 70 and the prompt component 80 can be separated from the lubricant, thereby avoiding the influence of the lubricant. At the same time, in order to ensure the transmission coordination between the transmission end and the transmission component 70, the transmission end is set as a magnetic end in this embodiment, and the transmission component 70 is a magnetic component. In this way, the transmission end and the transmission component 70 can be matched magnetically, and the magnetic end and the transmission component 70 have the same magnetic pole, so that when the magnetic end moves, it can drive the transmission component 70 to move together through magnetic attraction, thereby achieving the effect of triggering the prompt component 80.
[0044] In this embodiment, the triggered end of the prompt component 80 is arranged at the top of the second installation cavity 13, and the trigger end is arranged on the upper surface of the transmission member 70. When the transmission member 70 moves upward to the right position, the trigger end can trigger the triggered end, thereby triggering the prompt component 80. When the remaining amount of lubricant is higher than the predetermined amount, when the first magnetic member 30 drives the stirring member 60 to move upward through the connecting section 31, the stirring member 60 is subjected to the resistance of the lubricant, so that the displacement of the stirring member 60 moving upward is small. At this time, the stirring member 60 cannot drive the transmission member 70 to move upward to the position of triggering the prompt component 80, thereby failing to trigger the prompt component 80; and when the lubricant in the lubrication cavity 12 is exhausted and lower than the predetermined amount, the stirring member 60 loses the liquid resistance of the lubricant, thereby driving the transmission member 70 to move upward for a greater distance, so that the transmission member 70 can trigger the prompt component 80 to give a prompt alarm, so that after the lubricant is used up, it is convenient for the staff to know its usage, thereby facilitating the staff to add and use the lubricant.
[0045] like Figure 5 As shown, in this embodiment, the circuit board cutting device also includes a fixing ring 90 and a cleaning piece 100. The fixing ring 90 is sleeved on the outer peripheral side of the end of the rotating shaft 21 and is connected to the cutting table 10. The cleaning piece 100 can be a brush or other components. The cleaning piece 100 is arranged 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 piece 100 contacts the rotating shaft 21, and the debris and other impurities cut out by the cutting knife 20 can be cleaned by rotation, so as to prevent the 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, and causing blockage and jamming, thereby improving the rotation efficiency of the rotating shaft 21.
[0046] like Figure 1As shown, the cutting knife 20 of this embodiment includes a disc-shaped knife body part and a rotating shaft 21 arranged at the center of the end face of the knife body, and the rotating shaft 21 is arranged at the center of the two opposite end faces of the knife body, so that the knife body can be supported by the rotating shafts 21 on both sides to ensure stable rotation. Based on this, the cutting table 10 of this embodiment includes a central installation cavity 14 and two first installation cavities 11, wherein the two first installation cavities 11 are respectively located on both sides of the central installation cavity 14, and are in a mutually connected relationship, the central installation cavity 14 is used to accommodate the knife body, and the top of the knife body can extend from the upper opening of the central installation cavity 14, so as to achieve the cutting effect on the circuit board, the rotating shafts 21 on both sides of the knife body are respectively located in the two first installation cavities 11, and the two rotating shafts 21 are respectively provided with matching first magnetic parts 30, second magnetic parts 40 and other parts, so that both sides of the rotating shaft 21 can be automatically and continuously lubricated by lubricant.
[0047] Embodiment 2
[0048] The circuit board cutting device of this embodiment includes a cutting table 10, a cutting knife 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 knife 20 is rotatably arranged in the first mounting cavity 11 and is located below the lubrication cavity 12; the bottom of the lubrication cavity 12 has a lubrication port, and the first magnetic component 30 is movably arranged at the lubrication port, and has a closed position for shielding the lubrication port and an open position for avoiding the lubrication port; the second magnetic component 40 is connected to the rotating shaft 21 and rotates synchronously, and the second magnetic component 40 can cooperate with the first magnetic component 30 magnetically 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, and a first magnetic member 30 and a second magnetic member 40 are provided, wherein the first magnetic member 30 can control the lubrication port of the lubrication cavity 12. When the first magnetic member 30 blocks the lubrication port, the first magnetic member 30 closes the lubrication port so that the lubrication cavity 12 is not connected to the first installation cavity 11, and the lubricant in the lubrication cavity 12 cannot enter the first installation cavity 11, so it will not leak out, and the second magnetic member 40 plays a role in controlling the first magnetic member 30. It is arranged on the rotating shaft 21, so when the device works normally, the rotating shaft 21 rotates, and the rotation of the rotating shaft 21 drives the second magnetic member 40 to switch between positions close to and away from the first magnetic member 30. When the second magnetic member 40 approaches the first magnetic member 30, the second magnetic member 40 drives the first magnetic member 30 to move, so that the second magnetic member 40 switches to the open position. At this time, the lubrication port is opened, and the lubricating oil in the lubrication cavity 12 can flow to the rotating shaft 21 below through the lubrication port, and lubricate the rotating shaft 21 as the rotating shaft 21 rotates. As the rotating shaft 21 rotates, the lubrication port switches back and forth between the open and closed states, so that the lubricant intermittently flows from the lubrication cavity 12 to the rotating shaft 21, so that the rotating shaft 21 is continuously lubricated during the working process, ensuring that the cutting knife 20 can move smoothly. The above-mentioned setting method realizes lubrication when the rotating shaft 21 drives the cutting knife 20 to work, and there is no need for the staff to regularly lubricate the outer wall of the rotating shaft 21, thereby reducing the operating steps for the staff to use the circuit board cutting device, thereby improving the work efficiency of the staff in using the circuit board cutting device to cut the circuit board.
[0050] In this embodiment, the first magnetic member 30 moves downward from the closed position to the open position, so that when the first magnetic member 30 moves to the open position, it can also avoid the lubrication port to open the lubrication port. However, unlike the first embodiment, the above-mentioned setting method of this embodiment needs to take into account the interference between the first magnetic member 30 and other components when it moves downward when it is used, and it is necessary to ensure that the first magnetic member 30 moves downward, that is, moves in the direction close to the rotating shaft 21, without interfering with other components, so as to ensure the stability and safety of the overall operation.
[0051] Based on the above configuration, this embodiment adopts the form that the magnetic poles of the first magnetic component 30 and the second magnetic component 40 are the same. At this time, when the second magnetic component 40 faces the first magnetic component 30, it can drive the first magnetic component 30 to move downward, thereby opening the lubrication port.
[0052] In this embodiment, the circuit board cutting device further includes an oil brush 50, which can be a brush or other structural form. The oil brush 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 dripping on the peripheral side of the rotating shaft 21 can be evenly applied to the entire peripheral side of the rotating shaft 21 under the action of the oil brush 50. The oil brush 50 is rotated and brushed, so that the lubricant on the surface of the rotating shaft 21 is evenly spread, thereby improving the effect of the lubricant on the outer wall of the rotating shaft. The lubricant in this embodiment is lubricating oil, and of course other types of lubricants can also be used.
[0053] In this embodiment, the circuit board cutting device further includes a stirring member 60 , which is connected to the first magnetic member 30 and disposed in the lubrication chamber 12 . When the first magnetic member 30 moves, the stirring member 60 is driven to move to stir the lubricant in the lubrication chamber 12 .
[0054] Specifically, in this embodiment, a connecting section 31 is provided on the side of the first magnetic part 30 facing the inside of the lubrication chamber 12. The connecting section 31 can be a non-magnetic part. The agitator 60 is a plate-shaped part, which is sleeved on the outside of the connecting section 31 and can move along the moving direction of the first magnetic part 30 under the drive of the connecting section 31. In this way, when the first magnetic part 30 moves under the drive of the second magnetic part 40, the first magnetic part 30 can also drive the agitator 60 to move, so that the agitator 60 can stir the lubricant in the lubrication chamber 12, thereby increasing the flow effect of the lubricant at the bottom of the lubrication chamber 12, avoiding its sedimentation, and thus improving the lubrication effect of the lubricant on the rotating shaft 21.
[0055] In this embodiment, the stirring member 60 not only stirs the lubricant to improve the lubrication effect, but also monitors the remaining amount of the lubricant. Specifically, the stirring member 60 has a transmission end, and the circuit board cutting device also includes a transmission member 70 and a prompt component 80. The transmission member 70 is in transmission cooperation with the transmission end, and the transmission member 70 moves under the drive of the transmission end; the prompt component 80 and the transmission member 70 can be triggered to cooperate. When the remaining amount of lubricant in the lubrication cavity 12 is lower than a predetermined amount, the transmission member 70 moves under the drive of the transmission end and triggers the prompt component 80. The prompt component 80 generates a prompt signal, which can be an audio-visual signal, etc., so as to prompt personnel to perform inspection operations.
[0056] In order to prevent the lubricant from affecting the electrically charged components such as the prompt component 80, the cutting table 10 of this embodiment also has a second installation cavity 13, and the second installation cavity 13 is separated from the first installation cavity 11, and the transmission component 70 and the prompt component 80 are both arranged in the second installation cavity 13, so that the transmission component 70 and the prompt component 80 can be separated from the lubricant, thereby avoiding the influence of the lubricant. At the same time, in order to ensure the transmission coordination between the transmission end and the transmission component 70, the transmission end is set as a magnetic end in this embodiment, and the transmission component 70 is a magnetic component. In this way, the transmission end and the transmission component 70 can be matched magnetically, and the magnetic end and the transmission component 70 have the same magnetic pole, so that when the magnetic end moves, it can drive the transmission component 70 to move together through magnetic attraction, thereby achieving the effect of triggering the prompt component 80.
[0057] In this embodiment, the triggered end of the prompt component 80 is arranged at the bottom end of the second installation cavity 13, and the trigger end is arranged on the lower surface of the transmission member 70. When the transmission member 70 moves downward to the right position, the trigger end can trigger the triggered end, thereby triggering the prompt component 80. When the remaining amount of lubricant is higher than the predetermined amount, when the first magnetic member 30 drives the stirring member 60 to move downward through the connecting section 31, the stirring member 60 is subjected to the resistance of the lubricant, so that the displacement of the stirring member 60 moving downward is small. At this time, the stirring member 60 cannot drive the transmission member 70 to move downward to the position of triggering the prompt component 80, thereby failing to trigger the prompt component 80; and when the lubricant in the lubrication cavity 12 is exhausted and lower than the predetermined amount, the stirring member 60 loses the liquid resistance of the lubricant, thereby driving the transmission member 70 to move downward for a large distance, so that the transmission member 70 can trigger the prompt component 80 to give a prompt alarm, so that after the lubricant is used up, it is convenient for the staff to know its usage, thereby facilitating the staff to add and use the lubricant.
[0058] In this embodiment, the circuit board cutting device also includes a fixing ring 90 and a cleaning piece 100. The fixing ring 90 is sleeved on the outer peripheral side of the end of the rotating shaft 21 and is connected to the cutting table 10. The cleaning piece 100 can be a brush or other component. The cleaning piece 100 is arranged 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 piece 100 contacts the rotating shaft 21, and can rotate and clean the debris and other impurities cut out by the cutting knife 20, so as to prevent the 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, causing blockage and the like, thereby improving the rotation efficiency of the rotating shaft 21.
[0059] It should be noted that, the multiple in the above embodiments refers to at least two.

[0061] 1. Solve the problem of complicated manual lubrication operation of cutting device in related technology;
[0062] 2. The rotating shaft drives the cutting knife to be lubricated when working, and the staff does not need to lubricate the outer wall of the rotating shaft regularly, thereby reducing the operating steps of the staff to use the circuit board cutting device, thereby improving the work efficiency of the staff to use the circuit board cutting device to cut the circuit board;
[0063] 3. The lubricant on the surface of the rotating shaft is evenly spread by rotating and brushing the oil brush, thereby improving the lubrication effect of the lubricant on the outer wall of the rotating shaft;
[0064] 4. The stirring member can stir the lubricant in the lubrication cavity, thereby increasing the flow effect of the lubricant at the bottom of the lubrication cavity and preventing it from settling, thereby improving the lubrication effect of the lubricant on the rotating shaft;
[0065] 5. The stirring member cooperates with the transmission member and the prompting component, so that when the remaining amount of lubricant in the lubrication cavity is lower than a predetermined amount, the prompting component generates a prompting signal, thereby prompting personnel to perform inspection operations;
[0066] 6. The cleaning piece can rotate and clean the debris and other impurities cut out by the cutting knife to prevent the 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, causing blockage and jamming, thereby improving the rotation efficiency of the rotating shaft.
