[0034] Embodiment 1:

[0035] As Figures 1 to 3As shown in the figure, a highly efficient fault-tolerant multi-nozzle mounter includes a workbench 1, a frame 2 provided on the workbench 1, and a moving device 3 provided at the upper end of the frame 2; and it also includes a square column tube 4, a lifting adjustment component 5, a nozzle component 6 and a vacuum tube. Among them, the moving device 3 is a conventional structure, having a lifting moving device, a lateral moving device and a longitudinal moving device to realize the adjustment and movement of the nozzle component in the up and down, front and back, left and right directions relative to the frame. The square column tube 4 is connected to the moving device 3 and can move in the up and down, front and back, left and right directions relative to the frame 2 under the drive of the moving device 3; the square column tube 4 is tightly connected to the moving device 3 and can freely move in the up and down, front and back, left and right directions of the frame 2 under the drive of the moving device 3, serving as the support and guiding structure of the entire nozzle component 6, and the outer side surface of the square column is flat, which is convenient for the positioning and installation of the lifting adjustment component 5. On the side surfaces of at least two of the lifting adjustment components 5; each lifting adjustment component 5 has an independent driving ability to adjust the position of the connected nozzle component 6 in the vertical direction. Preferably, the lifting adjustment component 5 is a cylinder. Each lifting adjustment component 5 is connected with a nozzle component 6; the nozzle component 6 can move in the up and down direction relative to the square column tube 4 under the drive of the lifting adjustment component 5; a strip hole 41 extending from its upper end to the lower end is provided at the position corresponding to each nozzle component 6 on the side surface of the square column tube 4; the strip hole 41 is provided on the side surface of the square column tube 4 to facilitate the connection between the vacuum tube and the nozzle component 6, and when the lifting adjustment component 5 adjusts the movement of the nozzle component 6, the strip hole 41 can facilitate sufficient movement space for the vacuum tube to maintain the connection stability between the vacuum tube and the nozzle component 6. On the other hand, the vacuum tubes can be concentrated in the square column to prevent the vacuum tubes from interfering with the movement of the nozzle component 6. Each nozzle component 6 is connected with a vacuum tube that sequentially passes through the upper opening and the inner cavity of the square column tube 4 and the corresponding strip hole 41.

[0036] The core of this highly efficient fault-tolerant multi-nozzle mounter lies in its fault-tolerant design. On the basis of the workbench 1, the frame 2 and the moving device 3, a square column tube 4, a lifting adjustment component 5 and a nozzle component 6 are added in combination. At least two lifting adjustment components 5 and the corresponding number of nozzle components 6 are provided. When a certain nozzle component 6 fails to work due to a fault, the remaining normal nozzle components 6 can automatically adjust their positions through the corresponding lifting adjustment components 5, take over the working area originally responsible for by the faulty nozzle component 6, ensure the normal picking and mounting of electronic components in this area, and achieve seamless replacement. This design greatly improves the fault-tolerant ability and flexibility of the production line. Even when a single nozzle component 6 fails, production can still be guaranteed without interruption.

[0037] Preferably, there are two lifting adjustment components 5; one lifting adjustment component 5 is connected to each of the two opposite sides of the square column tube 4. By designing the number of the lifting adjustment components 5 in this way, preferably two are adopted, and the same number of nozzle components 6 are also provided. When a certain nozzle component 6 fails to work, the other normal nozzle component 6 can automatically adjust its position through the corresponding lifting adjustment component 5, take over the working area originally responsible for by the faulty nozzle component 6, ensure the normal picking and mounting of electronic components in this area, and achieve seamless replacement. This design greatly improves the fault tolerance and flexibility of the production line. At the same time, the cost can also be controlled. Of course, according to requirements, the number of the lifting adjustment components 5 and the nozzle components 6 can be reasonably designed as needed. The number of both the lifting adjustment components 5 and the nozzle components 6 can be 3, 4, etc.

[0038] Embodiment 2:

[0039] As Figures 3 to 5 shown, this embodiment provides an efficient fault-tolerant multi-nozzle mounter. In addition to including the technical solutions of Embodiment 1 above, it also has the following technical features. The nozzle component 6 includes a nozzle head 61 and a suction body 62; the suction body 62 is connected to the lifting adjustment component 5; the top end of the suction body 62 is communicated with the vacuum tube; the nozzle head 61 is detachably connected to the lower end of the suction body 62. By detachably connecting the nozzle head 61 and the suction body 62, when a problem occurs in the nozzle component 6 and it is a problem with the nozzle head 61, such as the nozzle head 61 being blocked, the nozzle head 61 can be directly disassembled and replaced, reducing the disassembly and replacement of parts, not requiring overall replacement, improving the maintenance efficiency, and saving maintenance time. Preferably, the upper end of the nozzle head 61 is threadedly connected to the lower end of the suction body 62. Of course, the upper end of the nozzle head 61 and the lower end of the suction body 62 can also be detachably connected by using the existing conventional snap-locking method.

[0040] Specifically, the suction body 62 includes a suction cylinder 621, a spiral dust-proof filter element 622, and a pipe joint 623. The lower end of the suction cylinder 621 is detachably connected to the upper end of the nozzle head 61; the spiral dust-proof filter element 622 is embedded in the inner cavity of the suction cylinder 621; the lower end of the spiral dust-proof filter element 622 is communicated with the nozzle head 61; the upper end of the pipe joint 623 is communicated with the vacuum pipe; the lower end of the pipe joint 623 is connected to the upper end of the suction cylinder 621 and presses the upper end of the spiral dust-proof filter element 622; the upper end of the spiral dust-proof filter element 622 is communicated with the pipe joint 623. By combining the suction cylinder 621, the spiral dust-proof filter element 622, and the pipe joint 623, a spiral dust-proof filter element 622 is embedded in the inner cavity of the suction cylinder 621. The spiral path of the spiral dust-proof filter element 622 extends the air flow channel, effectively increasing the contact area between dust, particles and other impurities and the filter element material, thereby greatly increasing the filtration area and improving the filtration efficiency. This design breaks through the limitation that the air flow passes straight through the existing filter element, effectively reducing the problem of suction drop caused by inhaling impurities, improving the stability and accuracy of mounting, and further effectively reducing the failure rate of the nozzle assembly 6, thus improving the fault tolerance of the production line.

[0041] Preferably, the spiral dust-proof filter element 622 includes a lower straight pipe section 6221, a spiral filter pipe section 6222, a filter screen 6223, and an upper straight pipe section 6224 that are sequentially communicated from bottom to top; the lower end of the lower straight pipe section 6221 is connected to the lower end of the suction cylinder 621 and is communicated with the nozzle head 61; the upper end of the upper straight pipe section 6224 is connected to the pipe joint 623 and is communicated with the pipe joint 623; the filter screen 6223 is connected between the upper end of the spiral filter pipe section 6222 and the lower end of the upper straight pipe section 6224. By adopting the connection method from bottom to top, the lower straight pipe section 6221, the spiral filter pipe section 6222, the filter screen 6223, and the upper straight pipe section 6224 are sequentially connected together. Designing the spiral dust-proof filter element 622 in this way facilitates the structural installation and stably communicates with the nozzle head 61 and the pipe joint 623. At the same time, the spiral filter pipe section 6222 extends the air flow channel, effectively increasing the contact area between dust, particles and other impurities and the filter element material, thereby greatly increasing the filtration area and improving the filtration efficiency. In addition, the filter screen 6223 further enhances the filtration efficiency of the spiral dust-proof filter element 622.

[0042] Specifically, the spiral filter element pipe section 6222 includes a filter element pipe body 62221 and a spiral plate 62222; the spiral plate 62222 is fitted in the filter element pipe body 62221 in a matching manner; the spiral plate 62222 and the inner wall of the filter element pipe body 62221 form a spiral flow channel 62223. By providing the filter element pipe body 62221 and the spiral plate 62222 to form the spiral filter element pipe section 6222, the spiral plate 62222 and the inner wall of the filter element pipe body 62221 form a spiral flow channel 62223. Such a spiral flow channel 62223 can effectively increase the contact area between dust, particles and other impurities and the filter element material, thereby greatly increasing the filtration area, improving the filtration efficiency, and the filter screen 6223 further enhances the filtration efficiency of the spiral dust-proof filter element 622, prevents the suction nozzle assembly 6 from being blocked, and further improves the service life of the suction nozzle assembly 6.

[0043] The working principle of the high-efficiency fault-tolerant multi-nozzle mounter of the present invention is as follows:

[0044] During normal use, under the control of the control system of the high-efficiency fault-tolerant multi-nozzle mounter, the moving device 3 adjusts the square column body, the lifting adjustment assembly 5 and the suction nozzle assembly 6 to move above the workbench 1, and controls one of the lifting adjustment assemblies 5 to drive the suction nozzle assembly 6 to move and adjust the position of the suction nozzle assembly 6. For the working area responsible by the suction nozzle assembly 6, the vacuum device sucks and stops sucking through the vacuum pipe to the suction nozzle assembly 6 to ensure the normal picking and mounting of electronic components in this area.

[0045] When the suction nozzle assembly 6 fails, control the corresponding lifting adjustment assembly 5 of the suction nozzle assembly 6 to drive the suction nozzle assembly 6 to reset, control the other lifting adjustment assembly 5 to adjust the position of another suction nozzle assembly 6, and take over the working area originally responsible by the faulty suction nozzle assembly 6 to ensure the normal picking and mounting of electronic components in this area and achieve seamless replacement.

[0046] In summary, the embodiment of the present invention provides a high-efficiency fault-tolerant multi-nozzle mounter, wherein the high-efficiency fault-tolerant multi-nozzle mounter has the following advantages:

[0047] First, the core lies in the fault-tolerant design of the high-efficiency fault-tolerant multi-nozzle mounter. Based on the workbench 1, the frame 2, and the moving device 3, a square column tube 4, a lifting adjustment component 5, and a nozzle component 6 are added in combination. At least two lifting adjustment components 5 and the corresponding number of nozzle components 6 are provided. When a certain nozzle component 6 fails to work due to a fault, the remaining normal nozzle components 6 can automatically adjust their positions through the corresponding lifting adjustment components 5, take over the working area originally responsible for by the faulty nozzle component 6, ensure the normal picking and mounting of electronic components in this area, and achieve seamless replacement. This design greatly improves the fault-tolerant ability and flexibility of the production line. Even in the case of the failure of a single nozzle component 6, production can be ensured without interruption, and the faulty nozzle component 6 can be repaired and replaced during the production gap or planned downtime to restore its normal function.

[0048] Second, the square column tube 4 is tightly connected to the moving device 3. Driven by the moving device 3, it can move freely in the up and down, front and back, left and right directions of the frame 2, serving as the support and guiding structure for the entire nozzle component 6. Moreover, the outer side of the square column is flat, which is convenient for the positioning and installation of the lifting adjustment component 5. A strip hole 41 is provided on the side of the square column tube 4 to facilitate the connection between the vacuum tube and the nozzle component 6. When the lifting adjustment component 5 adjusts the movement of the nozzle component 6, the strip hole 41 can provide enough space for the movement of the vacuum tube to maintain the connection stability between the vacuum tube and the nozzle component 6. On the other hand, the vacuum tubes can be concentrated in the square column to prevent the vacuum tubes from interfering with the movement of the nozzle component 6.

[0049] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
