It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0033] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] Please see Figures 1 to 4 As shown, a preferred embodiment of the grinding and dust removal device of this utility model includes: a grinding mechanism 100, including a transfer component, a mounting plate 110 pulverizedly connected to the transfer component, and a grinding component 120 disposed on the mounting plate 110 for grinding products, the grinding component 120 including a grinding head 121; and a first dust removal mechanism 200, including a first lifting drive component 210, a first suction head 220, and a first negative pressure source (not shown), the first lifting drive component 210 being disposed on the mounting plate 110 and pulverizedly connected to the first suction head 220, the bottom of the first suction head 220 being provided with a connection to the first negative pressure source. A first suction port 221 is connected; wherein, a first suction head 220 is sleeved on the grinding assembly 120 near the bottom, and the working end of the grinding head 121 protrudes relative to the bottom of the first suction head 220. A ring of first bristles 230 is provided around the bottom periphery of the first suction head 220. The first suction head 220 is adapted to move downward under the drive of the first lifting drive member 210 so that the first bristles 230 are pressed against the grinding area surface of the product and enclose the working end of the grinding head 121, or move upward so that the first bristles 230 are lifted away from the grinding area surface of the product and the enclosement of the grinding head 121 is released.

[0036] This invention, by mounting a first dust removal mechanism 200 on a grinding mechanism 100, allows the first dust removal mechanism 200 to move synchronously with the grinding assembly 120 as it moves to different grinding positions under the drive of the transfer component. This ensures the first dust removal mechanism 200 remains close to the product being ground, improving dust removal efficiency. The first dust removal mechanism 200 includes a first lifting drive component 210 and a first suction head 220. The first suction head 220 is fitted onto the grinding assembly 120 near its bottom, with the working end of the grinding head 121 protruding relative to the bottom of the first suction head 220. The first brush head 220 is provided with a first bristle 230. Before grinding by the grinding head 121, the first dust suction head 220 can move downward under the drive of the first lifting drive 210, so that the first bristle 230 is pressed against the surface of the grinding area of ​​the product to enclose the working end of the grinding head 121, so as to prevent dust from flying during grinding. At the same time, the first dust suction port 221 can reliably and efficiently suck up dust, effectively preventing dust residue inside the grinding equipment. The liftable first dust suction head 220 can adaptively adjust the lifting height to achieve the best enclosure effect. It can also be lifted upward when disassembling and replacing the grinding head 121 to avoid obstructing the grinding head 121.

[0037] Furthermore, the transfer assembly is composed of a lateral movement module and a lifting module 130, both of which are linear modules. There are two lateral movement modules, with one module being driven to the other, and they move along mutually perpendicular first and second horizontal directions respectively. The lifting module 130 is driven to the lateral movement module and can move vertically. The mounting plate 110 is driven to the lifting module 130.

[0038] Furthermore, the grinding assembly 120 includes a grinding drive 122 and a grinding spindle 123. The grinding drive 122 is disposed on the mounting plate 110 and located above the first suction head 220. The grinding spindle 123 passes vertically through the first suction head 220, with its upper end connected to the output end of the grinding drive 122 and its lower end connected to the grinding head 121 via the first suction port 221. Specifically, the grinding drive 122 can be a rotary motor, and the grinding spindle 123 is adapted to rotate relative to the first suction head 220 under the drive of the grinding drive 122.

[0039] Preferably, in this embodiment, the grinding spindle 123 is an electric spindle suitable for automatic tool changing, and the grinding head 121 is a detachable structure adapted to the grinding spindle 123, so that the grinding dust removal device can automatically change tools as needed to meet different grinding requirements. The grinding spindle 123 is a conventional structure, and will not be described in detail here.

[0040] Furthermore, the first lifting drive component 210 can be a linear cylinder or electric cylinder arranged in the vertical direction. In this embodiment, an electric cylinder is preferred to improve lifting accuracy and meet different lifting height requirements. The first suction head 220 has a hollow shell structure, with a clearance opening (not shown) on its top for the grinding spindle 123 to extend into. The clearance opening corresponds to the first suction port 221. The side of the first suction head 220 has a first dust outlet 222 that communicates with the first negative pressure source. A first suction pipe 240 is connected between the first dust outlet 222 and the first negative pressure source. The first suction pipe 240 is at least partially flexible to avoid obstructing the lifting and lowering of the first suction head 220. The first negative pressure source can specifically be a vacuum cleaner to apply negative pressure to the first suction pipe 240.

[0041] Since the product is a circuit board, in this embodiment, the outer contour of the first suction head 220 is preferably square or approximately square, so that the contour of the first bristles 230 arranged along the periphery of the first suction head 220 is square, so as to better enclose the surface of the grinding area of ​​the product. The first suction port 221 is a circular port coaxial with the grinding spindle 123, and the first suction port 221 is located in the middle region of the bottom of the first suction head 220. An annular area for dust suction is formed between the grinding spindle 123 and the first suction port 221, and between the grinding head 121 and the first suction port 221. A sealing structure can be provided between the clearance port and the grinding spindle 123 to prevent dust from flowing from the top of the first suction head 220 to the outside. For example, the sealing structure can be a sealing ring. The sealing structure allows the first suction head 220 to move up and down in the vertical direction and allows the grinding spindle 123 to rotate.

[0042] Furthermore, the grinding dust removal device also includes a second dust removal mechanism 300 disposed on the mounting plate 110, located on one side of the grinding mechanism 100. The second dust removal mechanism 300 includes a second lifting drive 310, a second suction head 320, and a second negative pressure source. The second lifting drive 310 is tractively connected to the second suction head 320 to drive the second suction head 320 to rise and fall vertically. The bottom of the second suction head 320 has a second suction port 321 communicating with the second negative pressure source. A ring of second bristles 330 is provided around the bottom periphery of the second suction head 320, which is suitable for cleaning the surface of the grinding area of ​​the product. Since the second bristles 330 are located around the bottom periphery of the second suction head 320, they surround the second suction port 321, thus the second bristles 330 do not obstruct the suction of the second suction port 321 while also preventing dust from easily scattering around the second suction port 321.

[0043] In one embodiment, the second lifting drive 310 can be disposed on the mounting plate 110. In this embodiment, it is preferably disposed at the output end of the first lifting drive 210. A connecting plate 211 can be disposed at the output end of the first lifting drive 210. Both the first suction head 220 and the second lifting drive 310 are mounted on the connecting plate 211. With the above structure, the second dust removal mechanism 300 can rise and fall synchronously with the first lifting drive 210, thereby reducing the lifting stroke of the second lifting drive 310 and making the lifting more reliable. The second lifting drive 310 only needs to adopt a cylinder structure, and can perform independent cleaning operations without being obstructed by the first suction head 220, while maintaining good lifting accuracy.

[0044] Furthermore, the second suction head 320 has a cylindrical structure, making the outline of the second bristles 330 at the bottom of the second suction head 320 circular. This structure can better target and clean the surface of the grinding area. The second suction head 320 has a hollow through-structure in the vertical direction, and its top is provided with a second dust outlet 322. A second suction tube 340 is connected between the second dust outlet 322 and the second negative pressure source. The second suction tube 340 is at least partially flexible.

[0045] The working process of this grinding device is as follows: The transfer component drives the grinding component 120 to move so that the working end of the grinding head 121 contacts the position of the product to be ground. Then, the first lifting drive component 210 drives the first dust suction head 220 to descend, so that the first bristles 230 contact the surface of the grinding area of ​​the product. At this time, the grinding head 121 surrounds the first bristles 230 and the surface of the grinding area of ​​the product. Then, the grinding drive component 122 drives the grinding head 121 to rotate to grind the product. The transfer component can move horizontally as needed to expand the grinding area. During the grinding process, the dust generated is blocked by the first brush bristles 230, and the first suction head 220 can concentrate and efficiently suck up the dust. After grinding, the grinding head 121 and the first suction head 220 rise and move away from the product. The second lifting drive 310 drives the second suction head 320 to descend so that the second brush bristles 330 contact the grinding area surface of the product. Then, the transfer component drives the second suction head 320 to move horizontally to clean the stubborn dust remaining on the product surface. At the same time, the second suction port 321 can effectively suck up the cleaned dust.

[0046] Furthermore, this utility model also provides a grinding device, including the aforementioned grinding dust removal device.

[0047] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
