[0002] The dispensing device is a coating tool used in the automation industry to precisely control fluids. It is generally driven by air pressure or mechanically controlled to achieve precise dripping and coating of fluids on the surface of the workpiece. The fully automatic dispensing equipment uses an automated control system to achieve automated dispensing operations, including automatic positioning, automatic filling, automatic detection and other functions, thereby greatly improving production efficiency.

[0003] When using automated dispensing equipment to perform dispensing and coating operations on workpieces to be processed, the workpiece to be processed is placed on an operating table, which will drive the workpiece to be processed to move and position according to the program set on the operating panel. However, during the movement of the operating table, the workpiece to be processed may shift on the operating table due to insufficient friction and other reasons, which will cause the dispensing position to shift, thereby reducing the processing accuracy of the dispensing device. Utility Model Content

[0004] The utility model proposes a dispensing device with automatic positioning function to solve the problem that during the movement of the operating table, the workpiece to be processed may shift on the operating table due to insufficient friction, etc., which will cause the dispensing position to shift and reduce the processing accuracy of the dispensing device.

[0006] The effect achieved by the above components is: by setting up two clamping plates, and rotating the two threaded rods under the action of two threaded rods respectively, the two threaded rods will respectively drive a clamping plate connected to the screw hole block to move toward each other on the top of the operating table until the two clamping plates completely clamp both sides of the workpiece to be processed, so that the workpiece to be processed and the operating table can be fixed, which is beneficial to prevent the workpiece to be processed from shifting on the operating table and reducing the impact on the processing accuracy of the dispensing device.

[0007] Preferably, a bearing is fixedly connected to the outer surface of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the connecting block.

[0008] The effect achieved by the above components is that by providing the bearing, the friction between the threaded rod and the connecting block can be reduced when the threaded rod is rotated, making it easier to rotate the threaded rod.

[0009] Preferably, the ends of the two threaded rods that are away from each other are fixedly connected to an operating block, and the outer surface of the operating block is provided with a protrusion.

[0010] The effect achieved by the above components is: by setting the operating block, rotating the operating block can drive the two threaded rods to rotate, and at the same time, the outer surface of the operating block is provided with a protrusion, which can effectively increase the friction force of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, a slider is fixedly connected to the bottom of the splint, a sliding groove is provided on the top of the operating table, and the outer surface of the slider is slidably connected to the inner wall of the sliding groove.

[0013] Preferably, the adjacent sides of the two clamping plates are fixedly connected with rubber plates, and grooves are evenly arranged on one side of the rubber plates.

[0014] The effect achieved by the above components is: by setting a rubber plate with grooves, one side of the replacement clamping plate can abut against the outer surface of the workpiece to be processed, which can increase the friction between the clamping plate and the workpiece to be processed, making the fixation of the workpiece to be processed more stable.

[0016] The effect achieved by the above components is: by setting two clamping blocks, the external pipe is sleeved on the outer surface of the feed pipe. Under the action of the spring, the spring will squeeze the clamping block so that one side of the clamping block abuts against the outer surface of the external pipe. The two clamping blocks can assist in reinforcing the connection between the external pipe and the feed pipe, which is beneficial to prevent the external pipe from detaching from the feed pipe and facilitate the normal input of the rubber material.
