Description

Technical Field

[0001] This utility model relates to the field of dispensing machines, and in particular to a five-axis automatic dispensing machine. Background Technology

[0002] Dispensing machines, also known as glue coating machines, dripping machines, glue spraying machines, or potting machines, are automated machines specifically designed to control fluids and apply them to the surface or interior of products. They can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and prevent stringing, leakage, and dripping. Dispensing machines are mainly used in product manufacturing processes to accurately dispense, inject, coat, or drip glue, applying it to precise locations on each product. They can be used to apply dots, lines, circles, or arcs.

[0003] For example, a five-axis vision dispensing machine disclosed in existing patent number 202323258017.0 includes a dispensing machine body, a dispensing base installed on the top of the dispensing machine body, a Y-axis guide rail positioned in the middle of the dispensing base, a support frame positioned at the rear of the dispensing base, an X-axis guide rail positioned on the top of the support frame, a Z-axis guide rail movably arranged at the front end of the X-axis guide rail, a slide movably arranged at the upper end of the Y-axis guide rail, and a rotary drive motor installed on the side of the slide. Although five-axis dispensing is achieved, the dispensing plate is fixedly connected to the rotation shaft of the rotary motor. When dispensing workpieces of different sizes and shapes, changing the dispensing plate is cumbersome, resulting in low work efficiency.

[0004] Therefore, it is necessary to propose a five-axis automatic dispensing machine to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a five-axis automatic dispensing machine that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A five-axis automatic dispensing machine includes a frame. An X-axis linear motor, a Z-axis linear motor, and a Y-axis linear motor are installed in the inner cavity of the frame. A mounting bracket is installed at the drive end of the Z-axis linear motor. The dispensing machine body is installed on the outer wall of the mounting bracket. A first rotary axis assembly is movably connected to the top of the Y-axis linear motor. A second rotary axis assembly is provided at one end of the first rotary axis assembly. A connecting component is provided on the top of the second rotary axis assembly. A quick-change contour jig is installed on the top of the connecting component.

[0008] Preferably, support frames are symmetrically installed on both sides of the inner cavity of the frame, the X-axis linear motor is installed on the top of the support frame, and the Z-axis linear motor is installed on the drive end of the X-axis linear motor.

[0009] Preferably, a drive frame is installed at the bottom of the first rotary shaft assembly, the drive frame is installed at the Y-axis linear motor, and heat dissipation grooves are formed on the outer walls of both the first rotary shaft assembly and the second rotary shaft assembly.

[0010] Preferably, the first rotary axis assembly is connected to the second rotary axis assembly via a first drive shaft, the second rotary axis assembly is connected to the connecting assembly via a second drive shaft, the first drive shaft and the second drive shaft are placed vertically, and the first drive shaft is placed parallel to the Y-axis linear motor.

[0011] Preferably, an origin sensing device is installed on the side of the top of the second rotating shaft assembly, the origin sensing device being used to detect whether the first drive shaft and the second drive shaft have moved to the origin position.

[0012] Preferably, the top of the connecting component has symmetrically provided positioning holes on both sides, and the bottom of the contour jig has symmetrically provided positioning posts on both sides. The positioning posts and positioning holes are on the same axis. The positioning posts are inserted into the inner cavity of the connecting component through the positioning holes. The top of the connecting component has a negative pressure adsorption groove in the center. The contour jig is adsorbed onto the top of the connecting component through the negative pressure adsorption groove. The outer wall of the connecting component is connected to a negative pressure pipe that communicates with the negative pressure adsorption groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This five-axis automatic dispensing machine, through the setting of a contour jig, can clamp the material to be dispensed. By activating the X-axis and Z-axis linear motors, the dispensing machine body can be adjusted in two axial directions. By activating the Y-axis linear motor, the first rotary axis assembly, and the second rotary axis assembly, the material clamped to the contour jig can be adjusted at multiple angles. This allows for a total of five-axis adjustment, effectively improving the dispensing accuracy and range, and increasing the efficiency of the dispensing process.

[0015] 2. This five-axis automatic dispensing machine, through its negative pressure adsorption tank, can adsorb the contour jig, making it easy to replace the contour jig according to the size and shape of the material. At the same time, when installing the contour jig, it can be positioned with positioning columns and positioning holes, which can further improve the stability of the contour jig and effectively ensure the efficiency and accuracy of dispensing.
