[0002] A grinding head is a general term for a small, shanked grinding tool used in electric grinders, pendant grinders, and hand drills. There are many types, including ceramic grinding heads, rubber grinding heads, diamond grinding heads, and abrasive cloth grinding heads. Ceramic grinding heads: The abrasive grains (generally brown corundum, white corundum, chromium corundum, or silicon carbide) are sintered from a ceramic binder, with a metal shank in the center.

[0110] The principle of the grinding head screening assembly f: The grinding head passes through the feeding guide rail to the feeding inclined rail. When the grinding head rod groove faces the outlet direction of the feeding inclined rail, the limiting rod of the pendulum will be inserted into the grinding head rod groove. When the grinding head is being fed, it is blocked by the limiting rod and rises to a certain angle. Then it will fall into the discharge inclined rail and then follow the discharge guide rail to discharge. When the grinding head rod groove faces away from the outlet direction of the feeding inclined rail, the grinding head will push the pendulum forward when it is being fed. Then it will fall into the return inclined rail and then be fed again along the return guide rail. This can realize the screening of the grinding head and ensure the discharge direction of the grinding head rod groove.

[0111] The working principle of this utility model is as follows: When in use, the material is first fed through the vibrating plate of the grinding head. During the feeding process, the material is screened through the screening assembly to ensure that the grinding head rod groove of the grinding head faces away from the turntable clamp. The material is then fed from the grinding head to the grinding head feeding assembly.

[0112] The grinding heads are fed through the grinding head feeding assembly. The translation platform of the grinding head translation assembly is moved to the discharge port side of the discharge guide rail by the first drive device. The grinding heads are sequentially fed onto the discharge guide rail by the grinding head vibratory plate. After being conveyed to the discharge port of the discharge guide rail, the grinding heads enter the translation platform. Then, the second drive device of the grinding head limiting assembly drives the connecting frame to move downwards. The corresponding sleeve moves downwards, pressing down the spring, which in turn drives the limiting rod to move downwards. The limiting top block presses down on the next grinding head (during this process, a spring is provided to provide cushioning and prevent damage to the grinding head). Then... The first drive device drives the moving table to move away from the discharge port side of the discharge guide rail. Then, the fourth drive device drives the push rod to move down between the moving table, the discharge guide rail and the discharge port. Then, the third drive device drives the push table to move towards the grinding head on the moving table. The corresponding push rod moves to push the grinding head towards the turntable clamp. During this process, the opening and closing device first lifts the upper clamping block. After the grinding head enters between the upper and lower clamping blocks, the opening and closing device retracts. The lower clamping block presses down to clamp the grinding head by gravity and the spring's rebound force.

[0113] After the grinding head is clamped and loaded, the turntable rotates to the dispensing device. During this process, an infrared sensor detects the presence of a grinding head to prevent it from being unloaded. Before dispensing, a glue cartridge filled with glue is inserted into the ceramic protective sleeve of the container. Then, the glue cartridge plug of the dispensing assembly is aligned with the glue cartridge. Next, the U-shaped bracket is rotated to align the top block of the locking rod with the back of the pneumatic mechanism of the dispensing assembly. Then, the locking rod is turned by the knob to lock the top block against the pneumatic mechanism, preventing the dispensing assembly from shifting during glue dispensing and affecting the dispensing effect. At the same time, the electric heating wire is activated. After heating, the glue canister is kept warm to prevent the glue from solidifying during dispensing. Since the glue canister is usually made of plastic, a ceramic protective sleeve is used for heat conduction to avoid direct heating of the glue canister, thus better protecting it and extending its service life. Then, the cylinder driven by the canister moves the dispensing device towards the turntable clamp, and then the glue is dispensed through the glue pushing assembly. After dispensing, the device moves back to the turntable clamp. After the glue is used up, the top block is unscrewed, the U-shaped frame is turned down, the glue pushing assembly is disassembled, the glue canister is removed, and a full glue canister is replaced.

[0114] After the glue is injected, the grinding head is driven by the turntable to the grinding head rod feeding assembly d. The grinding head rod is fed by the grinding head rod vibratory plate to the grinding head rod pneumatic clamp on the grinding head rod moving table for clamping. The subsequent grinding head rod is limited by the grinding head rod limiting assembly. The principle of the grinding head rod limiting assembly is the same as that of the grinding head limiting assembly. The grinding head rod driving cylinder drives the grinding head rod moving table to move towards the turntable clamp, inserting the grinding head rod into the grinding head rod groove of the grinding head. Then the grinding head rod pneumatic clamp is released, and the grinding head rod moving table is retracted to complete the grinding head rod feeding.

[0115] Then the rotating disk rotates to the centering device, and the grinding head rod is clamped in the grinding head rod centering groove by the two centering jaws of the first pneumatic gripper assembly. Then the centering motor drives the cylinder seat to rotate, and the corresponding two centering jaws rotate, which drives the clamped grinding head rod to rotate. Since the grinding head rod centering groove is aligned with the grinding head rod groove of the grinding head body for inserting the grinding head rod, after rotating a few times, the grinding head rod can be centered in the grinding head rod groove of the grinding head body.

[0116] The grinding head is centered at the rotating feeding device. The feeding drive mechanism drives the second pneumatic gripper to move towards the grinding head. The front and rear drive cylinders drive the front and rear moving platform to move backward. Then, the up and down drive cylinders drive the up and down sliding platform to move upward. Then, the left and right drive cylinders are activated to drive the pneumatic gripper to move towards the grinding head. The pneumatic gripper then clamps the grinding head rod of the grinding head body. The opening and closing device releases the gripper from the rotating table. Then, the front and rear drive cylinders drive the front and rear moving platform to move forward to above the feeding tray. The servo motor drives the rotating table to rotate 90° counterclockwise. At this time, the grinding head rod of the grinding head body is facing downward. Then, the up and down drive cylinders drive the pneumatic gripper to move downward and insert the grinding head rod into the grinding head insertion hole on the feeding tray. Then, the servo motor drives the rotating table to rotate back to the previous clamping position. This completes one grinding head rod installation process. The above process is repeated to form an assembly line.
