Description

Technical Field

[0001] The utility model relates to a positioning fixture for a dispensing machine, belonging to the field of positioning equipment for dispensing machines. Background Art

[0002] Dispensing machines are widely used in fields such as semiconductors, electronic components, and LCD manufacturing. Its principle is to press the glue into the feed pipe connected to the piston through compressed air. When the piston is moving upward, the piston chamber is filled with glue. When the piston is pushed downward, the glue is pressed out from the dispensing head. A plastic pipe head is bonded to the water outlet of the air conditioner water receiving tray, and the plastic pipe head is bonded with hot melt glue. In the prior art, manual dispensing and bonding of the pipe head are mostly adopted. Due to the long length of the water receiving tray, it is not convenient to operate, resulting in low processing efficiency. Moreover, considering cost and light weight, the main body of the air conditioner water receiving tray is usually made of foam. During the process of handling and fixing the position, the foam is easily broken due to collision and extrusion, and the yield rate of the product is also affected. Therefore, it is necessary to design a positioning fixture for a dispensing machine that can improve the processing efficiency of the water receiving tray. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a positioning fixture for a dispensing machine to solve the problems raised in the above background art. The utility model is convenient for quickly fixing the position of the water receiving tray and improving the processing efficiency of the water receiving tray.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A positioning fixture for a dispensing machine includes a positioning table. Two gantries are symmetrically installed above the positioning table. A cross bar is installed between the two gantries. The cross bar is located at the upper part of the gantry. A telescopic motor is installed above the cross bar. The output end of the telescopic motor is installed with a pressing plate. The pressing plate is located below the cross bar. A plurality of control buttons are installed on the front side of the positioning table. A support frame is installed above the positioning table. A driving member is installed inside the support frame. Two clamping plates are symmetrically installed inside the positioning table. A clamping member is installed on the side of the clamping plate close to the positioning table. A dispensing head is installed on the side of the support frame close to the pressing plate.

[0005] Further, the driving member includes a vertical motor. The vertical motor is installed on the top of the support frame. The output end of the vertical motor is installed with a guiding lead screw. The guiding lead screw is installed inside the support frame. A positioning block is installed on the guiding lead screw. Fixing blocks are installed on both sides of the positioning block. Clamping blocks are installed on the sides of the two fixing blocks close to the positioning block. The clamping blocks are installed in sliding grooves. The sliding grooves are opened on the positioning block.

[0006] Further, the two fixing blocks are respectively installed on the guide rod and the transmission lead screw. The guide rod is installed on the support frame. A first linear motor is installed on the front side of the support frame. The transmission lead screw is installed on the first linear motor. An activity groove is formed in the support frame. One end of the transmission lead screw is installed in the activity groove. The end of the fixing block away from the first linear motor is fixedly installed on the moving frame.

[0007] Further, a second linear motor is installed on one side of the moving frame. The output end of the second linear motor is installed with a driving lead screw. The driving lead screw is rotatably installed in the moving frame. A guiding base is installed on the driving lead screw. A glue dispensing head is installed on the front side of the guiding base.

[0008] Further, the clamping member includes a telescopic rod. One end of the telescopic rod is fixedly installed on the positioning table. A clamping plate is installed on the side of the telescopic rod away from the positioning table. A limiting groove is formed on the side of the clamping plate away from the telescopic rod. An inserting base is installed inside the limiting groove. A protective pad is installed on the front side inside the inserting base.

[0009] Further, the telescopic rod includes a sleeve. A spring is installed inside the sleeve. The other end of the spring is installed with a round rod. The other end of the round rod is installed with a clamping plate.

[0010] The beneficial effects of the present utility model: A positioning jig for a glue dispenser of the present utility model drives the guiding lead screw to rotate through a vertical motor, so that the positioning block drives the moving frame to move up and down. The first linear motor drives the transmission lead screw to rotate, so as to drive the fixing block to drive the moving frame to move horizontally back and forth, adapting to the distance between different water outlets and the support frame, facilitating the glue dispensing operation. Then, the second linear motor drives the driving lead screw to rotate, driving the glue dispensing head to move to the position of the water outlet for glue dispensing operation, improving the glue dispensing efficiency and saving the labor cost during glue dispensing.

[0011] Through the cooperation of the clamping block provided on one side of the fixing block and the sliding groove provided on the positioning block, the moving range of the fixing block is limited, avoiding the situation that the fixing block is separated from the positioning block caused by the continuous rotation of the transmission lead screw, and improving the stability of the glue dispensing head during the glue dispensing operation.

[0012] The spring inside the telescopic rod drives the clamping plate to squeeze both sides of the water receiving tray, so that the protective pad fits with the outside of the water receiving tray, fixing the position of the water receiving tray, avoiding the position deviation of the water receiving tray during the glue dispensing process, resulting in the failure of the glue dispensing operation, and the protective pad is made of soft rubber material, which can reduce the pressure exerted on both sides of the water receiving tray during the clamping process of the clamping plate and reduce the probability of damage to the water receiving tray.

By providing the guiding lead screw 11, the moving direction of the positioning block can be limited, so that the moving frame 14 can be driven to move up and down along the guiding lead screw 11.

[0022] Please refer to Figure 4 , the clamping member includes a telescopic rod 19, one end of the telescopic rod 19 is fixedly installed on the positioning table 1, a clamping plate 8 is installed on the side of the telescopic rod 19 away from the positioning table 1, a limiting groove 22 is opened on the side of the clamping plate 8 away from the telescopic rod 19, an inserting base 21 is installed inside the limiting groove 22, a protective pad 20 is installed on the front side inside the inserting base 21.
