[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0034] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0035] To better accommodate the corresponding smart integrated circuits, the circuit board carrying the smart integrated circuits needs to be precisely cut. To ensure precise cutting, laser cutting will be used to precisely cut the circuit board.

[0036] like Figures 1-5As shown, this embodiment provides a fully automatic circuit board laser processing device, which includes a main body 10, a fixing component 20, a laser cutting mechanism 30, a driving mechanism 40, a connecting mechanism 130, and a protective mechanism 50. The fixing component 20 is used to fix the workpiece; the laser cutting mechanism 30 is used to laser cut the workpiece; the driving mechanism 40 is disposed on the main body 10, and the driving mechanism 40 includes a sliding member 4c, which drives the laser cutting mechanism 30 to move; the protective mechanism 50 is covered on the driving mechanism 40, and the protective mechanism 50 is used to protect the driving mechanism 40 from dust; the connecting mechanism 80 is used to seal the sliding member 4c and the protective mechanism 50; the connecting mechanism 80 includes a holding component 81 and a positioning component 83; the holding component 81 can move to press the end of the protective component 50, and the positioning component 83 is used to fix and release the holding component 81; the control mechanism 60 is used to control the movement of the driving mechanism 40. The protective mechanism 50 is placed over the drive mechanism 40 and connected by the connecting mechanism 80. This prevents the dust generated by the laser cutting mechanism 30 from falling onto the drive mechanism 40 when it cuts the workpiece. This would prevent the dust from accumulating on the drive components of the drive mechanism 40 and causing jamming and accuracy deviations.

[0037] like Figures 2-5 As shown, optionally, the driving mechanism 40 includes a first driving component 41 and a second driving component 42; the first driving component 41 drives the laser cutting mechanism 30 to reciprocate, and the direction of reciprocating movement is a first displacement direction; the second driving component 42 drives the laser cutting mechanism 30 to reciprocate, and the direction of reciprocating movement is a second displacement direction; the first displacement direction and the second displacement direction are perpendicular; the two displacement directions of the laser cutting mechanism 30 enable the laser cutting mechanism 30 to cut the workpiece into the corresponding shape. By moving the laser cutting mechanism 30 in the first displacement direction and the second displacement direction, and the first displacement direction and the second displacement direction are perpendicular, the laser cutting mechanism 30 can cut the workpiece into the required corresponding shape. Its first displacement direction and second displacement direction are equivalent to the X-axis and Y-axis placed on the horizontal plane, and its workpiece is also placed horizontally. The laser cutting mechanism 30 moves in the X-axis and Y-axis directions to cut the horizontally placed workpiece.

[0038] like Figures 2-5As shown, optionally, there are two sets of first driving components 41 and one set of second driving components 42; the two sets of first driving components 41 are arranged in parallel, and the second driving components 42 are mounted on the sliding parts 4c of the two sets of first driving components 41. The sliding parts 4c of the two sets of first driving components 41 drive the second driving components 42 to translate along the first displacement direction; the laser cutting mechanism 30 is mounted on the sliding parts 4c of the second driving components 42, and the sliding parts 4c of the second driving components 42 drive the laser cutting mechanism 30 to translate along the second displacement direction. By using the second driving component 42 to be driven by the first driving component 41, and the laser cutting mechanism 30 to move independently on the second driving component 42, the workpiece can be effectively laser-cut according to the cutting requirements.

[0039] Optionally, the laser cutting mechanism 30 is perpendicular to the workpiece. The laser cutting mechanism 30 includes a laser cutting part and a driving component. The driving component can drive the laser cutting part away from or closer to the workpiece, and can adjust the distance between the laser cutting part and the workpiece according to the laser cutting requirements of different workpieces.

[0040] Optionally, a calibration unit is also included for calibrating the precise position of the laser emission.

[0041] Optionally, the calibration unit may use a reference piece placed on the main body and a calibration piece installed on the laser cutting mechanism 30. When the calibration piece is precisely aligned with the reference piece, it can locate the precise position of the laser cutting mechanism 30.

[0042] like Figures 3-5 As shown, optionally, both the first drive assembly 41 and the second drive assembly 42 include a power unit 4a and a track 4b; the laser cutting mechanism 30 is disposed on the sliding member 4c; the power unit 4a is used to drive the sliding member 4c to move along the track 4b, so that the laser cutting mechanism 30 cuts the workpiece. Under the precise path of the track 4b and driven by the power unit 4a, the laser cutting mechanism 30 moves precisely to the corresponding position.

[0043] like Figures 3-5 As shown, optionally, the power unit 4a includes a stator 4a1 and a mover 4a2; the stator 4a1 is disposed on the main body 10, and the mover 4a2 is disposed on the sliding member 4c. The mover 4a2 drives the sliding member 4c to move via the stator 4a1. Through the cooperation of the stator 4a1 and the mover 4a2, the movement of the laser cutting mechanism 30 can be stably realized.

[0044] Optionally, the stator 4a1 includes a permanent magnet steel plate; the mover 4a2 includes a conductive magnet; after the conductive magnet conducts electricity, it moves the mounting component under the magnetic attraction of the permanent magnet steel plate. This electromagnetic coordination forms the drive mechanism of the electromagnetic guide rail, which can prevent the noise generated when using gear transmission.

[0045] Optionally, there are two sets of tracks 4b, located on both sides of the stator 4a1. This design with two sets of tracks 4b ensures stable movement of the laser cutting mechanism 30.

[0046] like Figures 3-5 As shown, optionally, the protective mechanism 50 includes a frame portion 51 and a protective component 52; the upper end of the frame portion 51 is open, and the power unit 4a and the track 4b are located inside the frame portion 51; the protective component 52 is covered on the upper end of the frame portion 51, and the protective component 52 can extend and deform, so that the power unit 4a and the track 4b are sealed inside the frame portion 51. By placing the power unit 4a and the track 4b inside the frame portion, dust can be prevented from entering from the periphery and falling onto the power unit 4a and the track 4b. Furthermore, by using the protective component 52 to cover the frame portion 51, the power unit 4a and the track 4b are effectively sealed inside the frame portion 51, effectively preventing dust from falling onto the power unit 4a and the track 4b, thereby effectively preventing dust accumulation on the power unit 4a and the track 4b, which could lead to jamming and accuracy deviations.

[0047] like Figures 3-5 As shown, optionally, the protective assembly 52 includes multiple sets, each set of protective assemblies 52 being respectively disposed on both sides of the sliding member 4c; one end of the protective assembly 52 is sealed and fixed to the sliding member 4c, and the other end of the protective assembly 52 is fixedly installed to the frame part 51. By disposing of the protective assemblies 52 on both sides of the sliding member 4c, it is possible to prevent dust from falling onto the power part 4a and the track 4b, while also preventing the protective assemblies 52 from obstructing the movement of the sliding member 4c.

[0048] like Figure 3 , Figure 5As shown, optionally, the protective component 52 includes a first protective member 52a, a second protective member 52b, and a third protective member 52c; the first protective member 52a is disposed on the outside of the opening of the frame portion 51; the second protective member 52b is disposed on the inside of the first protective member 52a and is installed and fixed to the first protective member 52a, the first protective member 52a and the second protective member 52b constitute the first layer of protection; the third protective member 52c is located on the side of the second protective member 52b away from the first protective member 52a, the third protective member 52c is disposed on the outside of the power portion 4a and the track 4b, the third protective member 52c constitutes the second layer of protection. The first protective component 52a is placed over the outside of the opening in the frame portion 51, blocking a large amount of dust and providing initial dust protection, preventing a large amount of dust from falling into the frame portion 51. The second protective component 52b is placed inside the first protective component 52a and fixedly installed thereto, effectively filling any gaps left by the first protective component 52a and further blocking dust. The fixed installation of the second protective component 52b and the first protective component 52a ensures stable movement of the sliding component 4c. The third protective component 52c further addresses the issue of dust entering the frame portion 51 if gaps arise during movement between the second protective component 52b and the first protective component 52a.

[0049] Optionally, the first protective member 52a includes multiple partitions arranged in a stepped manner along the moving direction of the drive mechanism 40. By using the stepped arrangement of the first protective member 52a along the moving direction of the drive mechanism 40, the partitions will not obstruct each other during the driving process of the drive mechanism 40, thus preventing the drive mechanism 40 from failing to be driven.

[0050] Optionally, the partition is made of stainless steel, which can prevent dust from being deformed by pressing or contact, and prevent dust from falling into the frame part 51 due to the gap becoming larger.

[0051] like Figure 3 , Figure 5As shown, optionally, the second protective member 52b is a rectangular corrugated tube. The second protective member 52b is placed horizontally inside the frame portion 51, and the side of the second protective member 52b away from the first protective member 52a is open. Two upright plates 53 are provided inside the frame portion 51, located inside the second protective member 52b, and each upright plate 53 contacts one side of the second protective member 52b. The corrugated tube shape allows the second protective member 52b to deform while the sliding member 4c moves, ensuring the normal movement of the sliding member 4c. Furthermore, the opening on the side of the second protective member 52b away from the first protective member 52a prevents interference between the second protective member 52b and the power unit 4a and the track 4b. The upright plates 53 contacting one side of the second protective member 52b provide support and prevent dust from directly entering the power unit 4a and the track 4b from below the second protective member 52b.

[0052] Optionally, the material of the second protective component 52b may be one of rubber, plastic, or other materials.

[0053] Preferably, the second protective component 52b is made of rubber.

[0054] like Figure 3 , Figure 5 As shown, optionally, the third protective member 52c is a rectangular corrugated tube. The third protective member 52c is placed horizontally inside the frame portion 51, with the side of the third protective member 52c away from the opening of the frame portion 51 being open. The outer sides of both sides of the third protective member 52c contact the corresponding upright plate 53. By using the same corrugated tube shape as the second protective member 52b, the third protective member 52c can deform while the sliding member 4c moves, ensuring the normal movement of the sliding member 4c. The open side of the third protective member 52c away from the opening of the frame portion 51 prevents interference between the third protective member 52c and the power unit 4a and the track 4b. The contact between the outer sides of the third protective member 52c and the corresponding upright plate 53 ensures that even if dust passes over the upright plate 53 via the second protective member 52b, it will be blocked by the third protective member 52c.

[0055] Optionally, the third protective component 52c can be made of one of the following materials: nylon, rubber, etc.

[0056] Preferably, the third protective component 52c is made of nylon, which allows the incoming dust to adhere to the nylon and prevents the dust from moving further into the third protective component 52c.

[0057] like Figures 6-10As shown, optionally, a connecting mechanism 80 is also included. The connecting mechanism 80 is disposed at the end of the frame portion 51 of the sliding member 4c and the protective mechanism 50. The connecting mechanism 80 is used to seal the protective assembly 52 with the sliding member 4c and the end of the frame portion 51 and the protective assembly 52.

[0058] like Figures 6-7 As shown, optionally, the holding assembly 81 includes a clamping member 811 and a guide member 812; the ends of the sliding member 4c and the frame portion 51 are provided with guide grooves c1; the guide member 812 is fixedly connected to the clamping member 811, and the clamping member 811 is placed in the guide groove c1. Under the action of the guide groove c1, the clamping member 811 moves away from or near the end of the adjacent sliding member 4c or frame portion 51. When the clamping member 811 moves away from the end of the adjacent sliding member 4c or frame portion 51, the clamping member 811 is released, and the protective assembly 52 can be separated from the end of the sliding member 4c or frame portion 51. When the clamping member 811 moves near the end of the adjacent sliding member 4c or frame portion 51, the clamping member 811 tightly fixes the protective assembly 52 to the end of the sliding member 4c or frame portion 51.

[0059] Optionally, the connecting mechanism 80 further includes a third drive assembly 82; the third drive assembly 82 can drive the pressing assembly 81 to move; the third drive assembly 82 can drive the positioning assembly 83 to fix and release the pressing assembly 81. By driving the pressing assembly 81 and the positioning assembly 83 through the third drive assembly 82, it is convenient to achieve a sealed connection between the protective assembly 52 and the sliding member 4c, as well as the end of the frame portion 51 and the protective assembly 52.

[0060] like Figure 7 As shown, optionally, the third drive assembly 82 includes a drive member 821 and a support member 822; the ends of the sliding member 4c and the frame portion 51 are provided with a sliding groove c2; the support member 822 is fixedly connected to the pressing assembly 81, and the drive member 821 is used to drive the support member 822 to move along the sliding groove c2. When the support member 822 moves along the sliding groove c2, the support member 822 drives the pressing assembly 81 to press or release the protective assembly 52.

[0061] like Figure 7 As shown, optionally, the positioning component 83 includes a positioning element 831 and a positioning hole 832. The positioning element 831 is mounted on the support member 822, and the positioning hole 832 is located at the end of the sliding member 4c or the frame portion 51. The driving member 821 can rotate relative to the support member 822. The rotation of the driving member 821 can drive the positioning element 831 to insert into the positioning hole 832 or disengage from the positioning hole 832. When the positioning element 831 disengages from the positioning hole 832, the support member 822 can move along the slide groove c2 under the drive of the driving member 821, so that the pressing component 81 can move to press or release the protective component 52.

[0062] like Figures 7-8As shown, optionally, one side of the positioning member 831 is a friction surface, and the driving member 821 is provided with a friction wheel 84. The friction wheel 84 contacts the friction surface on the positioning member 831. When the driving member 821 drives the friction wheel 84 to rotate, the friction wheel 84 drives the positioning member 831 to insert into the positioning hole 832 or disengage from the positioning hole 832.

[0063] Optionally, the positioning component has a toothed groove on one side, and the driving component has a gear (not shown in the figure). The gear engages with the toothed groove on the positioning component. When the driving component drives the gear to rotate, the gear drives the positioning component 831 to insert into the positioning hole 832 or disengage from the positioning hole 832.

[0064] like Figures 6-8 As shown, optionally, a limiting member 85 is also included. The limiting member 85 is disposed on the driving member 821. The limiting member 85 is located on the upper side of the sliding member 4c or on the upper side of the end of the frame portion 51. When the driving member 821 rotates, the limiting member 85 rotates with the driving member 821 and can contact the upper side of the corresponding protective component 52, pressing down on the protective component 52 to keep the protective component 52 at the corresponding height of the frame portion 51 unchanged, preventing the problem of poor sealing caused by the protective component 52 not being placed at the corresponding height. When the limiting member 85 presses down on the protective component 52, the positioning member 831 disengages from the positioning hole 832, and the driving member 821 can drive the mounting member to move along the slide groove c2.

[0065] Optionally, the lower side of the limiting member 85 near the protective component 52 is a downward-facing slope, which causes the limiting member 85 to press down on the protective component 52 under the pressure of the slope.

[0066] Optionally, it also includes a plurality of sealing layers 86, which are respectively disposed at the ends of the sliding member 4c and the frame portion 51. When the clamping member 811 tightly fixes the protective assembly 52 to the end of the sliding member 4c or the frame portion 51, the sealing layer 86 tightly seals the protective assembly 52 to the end of the sliding member 4c or the frame portion 51.

[0067] like Figures 6-7 As shown, optionally, the sealing layer 86 is an elastic sealing layer 86; the material of the elastic sealing layer 86 can be one of rubber, silicone, etc., and no specific limitation is made here.

[0068] Optionally, the drive unit 821 is provided with a handle 87, which is used to drive the drive unit 821 to move and rotate.

[0069] The connection process of the connecting mechanism 80 is as follows: When installing the protective component 52, first rotate the drive member 821 to make the limiting member 85 press down on the protective component 52 so that the protective component 52 is placed at the corresponding height of the frame part 51 and remains unchanged; then push the drive member 821 to make the holding member 81 press the protective component 52, and rotate the drive member 821 to make the positioning member 831 be placed in the positioning hole 832, so that the protective component 52 is tightly fixed to the sliding member 4c or the end of the frame part 51 and does not detach. The operation is convenient and reduces the installation difficulty of the protective component 52. When removing the protective component 52, simply rotate the drive member 821 in the opposite direction to make the positioning member 831 disengage from the positioning hole 832, then push the drive member 821 to make the holding member 81 release the protective component 52, and then rotate the drive member 821 again to separate the pressing member 811 from the protective component 52. The protective component 52 can then be removed, reducing the removal difficulty, facilitating the cleaning of dust inside the protective component 52, and facilitating the maintenance of the drive mechanism 40 that protects the protective component 52.

[0070] like Figures 4-5 As shown, optionally, a displacement sensor 70 is also included; the displacement sensor 70 is used to detect the displacement distance, and the displacement sensor 70 transmits the signal to the control mechanism, which then controls the drive mechanism 40 to move. The design of the displacement sensor 70 enables more precise displacement of the drive mechanism 40, thereby ensuring the cutting accuracy of the workpiece.

[0071] like Figures 4-5 As shown, optionally, the displacement sensor 70 includes a grating ruler 71 and a grating reading head 72; the grating ruler 71 is disposed within the frame portion 51 and parallel to the track 4b, and the grating reading head 72 is mounted on the sliding member 4c, and the grating reading head 72 reads the values ​​on the grating ruler 71. The design of the grating ruler 71 and the grating reading head 72 ensures that their error is less than 0.02mm, guaranteeing the machining accuracy of the workpiece.

[0072] Optionally, the fixing component 20 includes a clamping member 21 that clamps the workpiece. Using the clamping member 21 for clamping ensures that the workpiece will not wobble during the cutting process, thus guaranteeing machining accuracy.

[0073] In summary, the present invention provides a fully automatic circuit board laser processing device. By covering the drive mechanism with a protective mechanism and connecting it with a connecting mechanism, it can prevent the dust generated by the laser cutting mechanism from accumulating on the drive components of the drive mechanism, thus preventing jamming and accuracy deviations.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
