[0002] Electronic components need to be polished during the manufacturing process. After the electronic component mainboard is firmly fixed, it is generally necessary to manually use a handheld polishing device to polish the surface of the electronic component mainboard.

[0029] Example 1

[0030] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a grinding device for processing electronic components, including a truss assembly 1, a base assembly 2 is arranged below the truss assembly 1, the truss assembly 1 grinds the electronic components in the horizontal direction to ensure the cleanliness of the surface, the base assembly 2 clamps and fixes the electronic components, so that the effect of fixing the electronic components is better, and the grinding effect is guaranteed. When the pressure applied by the base assembly 2 to the electronic components is too large, the side walls of the electronic components will no longer continue to be squeezed, so as to avoid the device continuing to apply pressure to the electronic components after clamping the electronic components and causing damage to the electronic components. When the base assembly 2 rotates, it drives the truss assembly 1 to slide downward, so that the truss assembly 1 is close to the electronic components, so that the truss assembly 1 can grind the side walls of the electronic components from the vertical direction, thereby improving the practicality of the device.

[0031] The base assembly 2 includes a bottom plate 21, and a plurality of hollow columns 211 are fixedly installed on the side wall of the bottom plate 21. The truss assembly 1 includes a plurality of vertical slide bars 14 slidably arranged inside the plurality of hollow columns 211, so that the vertical slide bars 14 are limited to slide inside the hollow columns 211, and the movement range of the equipment or device is limited, thereby preventing equipment damage and accidents from occurring, and ensuring that the equipment works in the correct position. The upper ends of the plurality of vertical slide bars 14 are fixedly connected to a field frame 11, and a grinding head 13 is slidably arranged below the field frame 11, and the electronic components are ground by the rotating grinding head 13, and the grinding head 1 The grinding head 13 slides horizontally between the side walls of the field frame 11, and the vertical slide bar 14 slides in the hollow column 211, driving the grinding head 13 to approach the bottom plate 21. When the grinding head 13 slides horizontally in the field frame 11, the grinding head 13 grinds the electronic components in the horizontal direction. When the field frame 11 slides down, the grinding head 13 slides horizontally, so that the grinding piece installed on the grinding head 13 can move to the side wall of the electronic component, and then grind the side wall of the electronic component. Therefore, the device can be adjusted according to different shapes and sizes of components, thereby improving the compatibility of the device with electronic components of different sizes.

[0032] A lifting block 12 is fixedly sleeved on the middle section of the vertical slide bar 14, and a turntable 22 is arranged between the plurality of lifting blocks 12. A thread is arranged on the side wall of the turntable 22, and the plurality of lifting blocks 12 are meshed with the turntable 22 through the screw grooves provided on the side wall. Through the screw engagement between the threads, the turntable 22 drives the lifting block 12 to slide downward when rotating, thereby making the grinding head 13 approach the electronic components, and the horizontal sliding cooperation can grind the top surface and side wall of the electronic components, greatly improving the grinding efficiency and processing accuracy. A material placing box 23 is fixedly connected above the turntable 22, and when the turntable 22 rotates, it drives the material placing box 23 to rotate, thereby driving the placing The electronic components on the material storage box 23 rotate, so that the staff can observe the electronic components being processed from multiple angles when the device is grinding the electronic components, and then timely observe the progress of the grinding of the electronic components to avoid damage to the electronic components due to excessive grinding. A sliding hole is opened above the material storage box 23, and two fixing clips 24 are arranged in the sliding hole. The fixing clips 24 pass through the sliding hole and slide above the material storage box 23. The electronic components are placed above the material storage box 23, and the two fixing clips 24 are close to each other to clamp and fix the electronic components, so that the position of the electronic components is fixed during processing, and deviations in product accuracy due to shaking of parts are avoided.

[0033] An optical axis 26 is rotatably installed above the bottom plate 21. The optical axis 26 passes through the material storage box 23 and is fixedly connected to the top of the turntable 22. The rotation of the optical axis 26 drives the turntable 22 to rotate. A second motor 262 is arranged below the optical axis 26. The rotating shaft of the second motor 262 passes through the bottom plate 21 and is fixedly connected to the optical axis 26. The optical axis 26 is driven to rotate by the rotating shaft of the second motor 262, and then the turntable 22 is driven to rotate, so that the electronic components can rotate while being polished, so as to facilitate the observation of the staff and avoid damage to the electronic components caused by excessive polishing.

[0034] Vertical plates 212 are fixedly installed on both sides of the bottom plate 21. Notches are opened on the upper sides of the vertical plates 212. A limit ring is arranged under the turntable 22. The turntable 22 is connected to the notches on the two vertical plates 212 through the limit ring and rotates. The moving range of the turntable 22 is limited by the two vertical plates 212, thereby preventing equipment damage and accidents and ensuring that the turntable 22 works in the correct position. The rotation of the turntable 22 drives the electronic components between the two fixing clamps 24 to rotate, so that the staff can observe the polishing progress of the electronic components 360° on one side to avoid damage to the electronic components due to excessive polishing.

[0035] A worm sleeve 261 is sleeved on the optical axis 26, and a first worm wheel 27 is rotatably installed on one side of the worm sleeve 261. When the first worm wheel 27 rotates, the worm sleeve 261 is driven to slide up and down. A second worm wheel 271 is coaxially connected to one side of the first worm wheel 27. A first worm 25 is meshed on a side of the second worm wheel 271 close to the optical axis 26. The rotation of the first worm 25 drives the second worm wheel 271 and the first worm wheel 27 to rotate, thereby causing the first worm wheel 27 to rotate and push the worm sleeve 261 to slide up and down. A first motor 251 is arranged below the first worm 25. The rotating shaft of the first motor 251 passes through the bottom plate 21 and is fixedly connected to the first worm 25. The first worm 25 is driven to rotate, and the two fixing clamps 24 are driven to approach each other through the up and down sliding of the worm sleeve 261, thereby clamping and fixing the electronic components. The electronic components can be flexibly clamped according to the sizes and specifications of different electronic components, so that the effect of fixing the electronic components is better and the grinding effect is guaranteed. Two screws 28 are rotatably installed inside the material storage box 23. The screw 28 passes through the fixing clamp 24 and meshes with the fixing clamp 24 through the thread. The threads on the two screws 28 are in opposite directions. Through the screwing between the threads, the two fixing clamps 24 are driven to approach each other when the screw 28 rotates, thereby clamping electronic components of different sizes, thereby improving the practicality of the device.

[0036] A third worm gear 281 is arranged between the two screw rods 28, and the worm sleeve 261 drives the third worm gear 281 to rotate. The rotation of the third worm gear 281 drives the two screw rods 28 to rotate, thereby making the two fixing clamps 24 approach each other, clamping and fixing the electronic components, making the effect of fixing the electronic components better, and ensuring the grinding effect. Disconnection components 29 are arranged on both sides of the third worm gear 281, and the third worm gear 281 is connected to the two screw rods 28 through the disconnection components 29 on both sides. When the two fixing clamps 24 clamp the electronic components, if the first motor 251 continues to work, the third worm gear 281 and the screw rod 28 are disconnected by the set disconnection component 29, so that the torque of the third worm gear 281 cannot continue to be transmitted to the two screw rods 28, and the two screw rods 28 cannot continue to drive the two fixing clamps 24 to continue to approach each other, thereby avoiding damage to the electronic components caused by excessive clamping force.

[0037] The disconnect assembly 29 includes a protective shell 291, which protects the internal structure to prevent wear debris from further damaging the inside of the protective shell 291 and causing the disconnect assembly 29 to fail. Two disc springs 292 are arranged inside the protective shell 291, and the two disc springs 292 are arranged with one bottom surface being convex and the other bottom surface being concave, and the convex sides of the two disc springs 292 squeeze each other, so that the two disc springs 292 are elastically deformed to store potential energy. A sprocket 293 is provided on the side close to the third worm gear 281. The sprocket 293 is fixedly connected to the screw 28. A plurality of concave teeth are provided on the side wall of the sprocket 293. Steel balls 294 are provided in the concave teeth. When the plurality of steel balls 294 rotate, the sprocket 293 is driven to rotate, and then the two fixing clamps 24 are driven to approach each other through the screw 28. A bite plate 295 is provided on the side close to the third worm gear 281 of the sprocket 293. A plurality of wedges are provided in an annular manner on the side close to the sprocket 293. The steel ball 294 is clamped between the two wedge blocks, and the steel ball 294 is fixedly connected to the bite plate 295 and the third worm gear 281. When the worm sleeve 261 slides upward, it pushes the third worm gear 281 to rotate, and finally the two fixing clamps 24 are close to each other. The disc spring 292 pushes a plurality of steel balls 294 to approach the bite plate 295, so that the screw 28 is connected to the third worm gear 281 through the sprocket 293, the steel ball 294, and the bite plate 295. When the two fixing clamps 24 clamp the electronic components, the third worm gear 281 is rotated. The reaction force of the force causes the bite plate 295 to push a number of steel balls 294 to squeeze the disc spring 292, making the contact between the two disc springs 292 closer, thereby compressing the space to cause the steel balls 294 to disengage from between the two wedge blocks, and then the third worm gear 281 no longer drives the screw 28 to rotate through the disconnect assembly 29, thereby preventing the second motor 262 from continuing to rotate after the electronic components are clamped, resulting in excessive clamping force input and damage to the electronic components, thereby effectively protecting the electronic components.

[0038] The present invention drives the material box 23 and the turntable 22 to rotate through the optical axis 26, and then uses the screwing between the threads to make the field frame 11 slide downward, so that the grinding head 13 electronic components are close to the electronics, and cooperates with the horizontally sliding grinding head 13, so that the device can grind the top surface and side wall of the electronic components, thereby improving the practicality of the device; the first worm 25 drives the first worm wheel 27 to rotate to push the worm sleeve 261 to slide, and then drives the third worm wheel 281 to rotate, and the disconnecting assembly 29 is used to connect the third worm wheel 281 and the screw 28 The connection causes the screw rod 28 to rotate and drive the two fixing clamps 24 to approach each other, thereby clamping and fixing electronic components of different specifications, improving the compatibility of the device while also improving the accuracy of grinding the electronic components; at the same time, after the two fixing clamps 24 clamp the electronic components, the third worm gear 281 and the screw rod 28 are disconnected by the provided disconnecting assembly 29, thereby preventing the two fixing clamps 24 from continuing to approach each other, avoiding damage to the electronic components due to excessive clamping force input, and effectively protecting the electronic components.
