Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] The circuit board is cut from raw materials. After the circuit board is just cut, there will be many burrs around it that need to be removed. The existing technology uses a grinding wheel to grind the top surface of the circuit board. After grinding, the ground surface of the circuit board is facing down and the tooling is fixed to the machine. Repeat the above operation to grind both sides of the circuit board.

[0028] In the related art, a grinding wheel is used to grind the top surface of the circuit board. After grinding, the circuit board is placed with the grinded surface facing downward and the tooling is fixed to the machine. The above operation is repeated to grind the bottom surface of the circuit board or both sides are grinded by adding a fixing device or making the fixing device rotatable. It is impossible to grind both sides at the same time, so the work efficiency is low and there are certain limitations.

[0029] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides a circuit board deburring device. When the circuit board needs to be deburred, it is only necessary to install the circuit board in the clamping plate 27, and then the grinding wheel 15 can be started to grind both sides of the circuit board at the same time, thereby improving the working efficiency of the deburring device.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 2 The embodiment of the present application provides a circuit board deburring device, including a grinding component 1; the grinding component 1 includes: a support leg 11, on which a base 12 is arranged; a support column 13, arranged on the base 12; a rotating shaft 14, arranged on the support column 13; a grinding wheel 15, arranged on the rotating shaft 14; a fixing component 2 is provided on the base 12, and the fixing component 2 includes: a motor 21, arranged on the base 12; and a threaded rod 22 connected to the rotating shaft 14, arranged on the base 12; a linear module 23, arranged on the base 12; a slider 24, arranged on the linear module 23; a fixing block 25, arranged on the slider 24; a spring 26, arranged on the fixing block 25; a clamping plate 27, arranged on the spring 26.

[0032] When we need to deburr the circuit board, we start the motor 21 on the threaded rod 22 to rotate the threaded rod 22, and at the same time drive the support column 13 to move the support column 13 to both sides. At the same time, the support column 13 drives the rotating shaft 14, and the rotating shaft 14 drives the grinding wheel 15 to move to both sides. This is to fix the circuit board. When the circuit board is inserted into the middle of the clamping plate 27, the spring 26 will be driven to contract, and at the same time, a force will be applied to the clamping plate 27 to complete the fixation of the circuit board. This is to start the motor 21 on the threaded rod 22 again to rotate the threaded rod 22, so that the above-mentioned support column 13, the rotating shaft 14 and the grinding wheel 15 move to the middle. When the grinding wheel 15 is close to the circuit board, turn off the motor 21 on the threaded rod 22, and then start the motor 21 on the support column 13 so that the motor 21 on the support column 13 drives The rotating shaft 14 drives the grinding wheel 15 to rotate to grind and deburr the circuit board. At the same time, the linear module 23 can be started, and the slider 24 is driven by the motor on the linear module 23 to move the slider 24 up and down. At the same time, the slider drives the fixed block 25 to move with the movement, driving the spring 26 and the clamping plate 27. At the same time, the clamping plate 27 drives the fixed circuit board to move up and down, so that different parts of the circuit board can be polished and deburred by the grinding wheel 15. After deburring is completed, the motor on the support column 13 is turned off, and the motor 21 on the threaded rod 22 is started to rotate the threaded rod 22, thereby driving the support column 13 and moving the support column 13 to both sides. At the same time, the support column 13 drives the rotating shaft 14, and the rotating shaft 14 drives the grinding wheel 15 to move to both sides, and then the circuit board can be taken out.

[0033] In some embodiments, the motor 21 is provided with a protective shell to extend the service life of the motor.

[0034] In some embodiments, the clamping plate 27 is provided with an inclined surface to assist the circuit board in being inserted into the clamping plate 27 .

[0035] In some embodiments, the threaded rod 22 is a mirror-image thread so that the support column can move to both sides or to the center at the same time.

[0036] In some embodiments, the linear module 23 is a linear motor module that can more accurately control the position of the grinding wheel 15 .

[0037] In some embodiments, a plurality of springs 26 are provided to increase the stability of fixing the circuit board.

[0038] In some embodiments, an auxiliary component 3 is disposed on the base 12 ; the auxiliary component 3 includes: a bracket 31 disposed on the base 12 ; and an electric fan 32 disposed on the bracket 31 .

[0039] When we deburr the circuit board, the polished debris may accumulate on the base 12. At this time, we turn on the electric fan 32 to blow out air to clean the debris and avoid the accumulation of debris.

[0040] In some embodiments, the electric fan 32 is provided with a casing to prevent the fan blades from being bumped or touched during operation, thereby improving safety.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
