[0002] Glue dispenser, also known as glue coating machine, glue dripping machine, glue spraying machine, etc., is an automated machine that controls fluids and drips and applies fluids to the surface or inside of products. This machine is widely used in many industries, such as semiconductors, electronic components, LCD manufacturing and other fields. The working principle of the glue dispenser is to press the glue into the feed pipe connected to the piston through compressed air. When the piston is in the upward rush, the piston chamber is filled with glue, and when the piston is pushed down, the glue is pressed out from the glue dispensing head. This machine is suitable for fluid dispensing, with a high degree of automation and a higher quality level of products.

[0003] The traditional dispensing machine only has one dispensing head that can be driven along the XYZ direction. When dispensing is required on the two sides of the workpiece, the dispensing head needs to be driven to move back and forth, which is not conducive to improving the dispensing efficiency. In addition, when the workpiece to be dispensed is replaced, the dispensing head is in a waiting state, causing the glue at the end of the dispensing head to cool down. The glue at the end needs to be discharged before dispensing, resulting in a waste of glue. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figures 1 to 4 As shown, the dispensing machine of the utility model includes: a frame 1, on which a gantry 2 is arranged, on which two groups of X-axis linear modules 3 with the same structure are installed, each X-axis linear module 3 is installed with a Z-axis linear module 5 for controlling the movement of a dispensing head 4 in the Z-axis direction, and the frame 1 is installed with a Y-axis linear module 6 for controlling the movement of a workpiece to be dispensed along the Y-axis direction directly below the gantry 2; a heating component, the heating component is arranged on the Z-axis linear module 5, and can selectively heat the dispensing head 4 that is not in operation.

[0028] See also Figure 1 , Figure 2 Two X-axis linear modules 3 with the same structure are installed on the gantry 2, and each X-axis linear module 3 is installed with a Z-axis linear module 5. The Z-axis linear module 5 is installed with a pushing cylinder 7 and a dispensing head 4. The dispensing head 4 can move vertically relative to the Z-axis linear module 5, and the pushing cylinder 7 is used to push the dispensing head 4 to move on the Z-axis linear module 5.

[0029] See also Figure 1 A tray 8 is installed on the Y-axis linear module 6. The tray 8 is used to place the workpiece to be glued. The Y-axis linear module 6 can drive the tray 8 to move along the Y-axis direction.

[0030] It should be noted that the models of the X-axis linear module 3, the Y-axis linear module 6 and the Z-axis linear module 5 can be one of X1B11-08 and X1B41-21. It is understandable that the linear module is a mature technology.

[0031] See also Figure 2 The heating component is installed on the Z-axis linear module 5 and can move synchronously with the push cylinder 7. When the dispensing head 4 is driven downward by the push cylinder 7 to perform dispensing operation on the workpiece, the heating component located below the dispensing head 4 will not interfere with the position of the dispensing head 4. After the dispensing head 4 completes the glue injection on the workpiece, the push cylinder 7 controls the dispensing head 4 to reset. At this time, the heating component in the heating component will move along the X-axis direction to the bottom of the dispensing head 4 to heat the dispensing head 4, thereby avoiding the problem of the glue inside the dispensing head 4 solidifying due to the temperature drop and reducing the waste of glue. At the same time, the present application drives the dispensing head 4 to dispense glue on both sides of the workpiece at the same time through two Z-axis linear modules 5 of the same structure, which can effectively improve the dispensing efficiency of the workpiece and has practicality.

[0032] In one or more embodiments, the heating assembly includes: a driving cylinder 9, which is horizontally installed on the Z-axis linear module 5 below the dispensing head 4; a supporting plate 10, which is connected to the extended shaft end of the driving cylinder 9; and a conical heater 11, which is installed on the supporting plate 10.

[0033] See also Figure 2 , Figure 3 A heating copper wire is arranged inside the conical heater 11 to achieve a heating effect. The conical heater 11 has a conical structure inside, thereby matching the shape of the dispensing head 4 and improving the uniformity of heating the dispensing head 4.

[0034] See also Figure 2 The driving cylinder 9 is fixedly installed on the Z-axis linear module 5 below the dispensing head 4. The driving cylinder 9 controls the conical heater 11 to extend into or withdraw from the bottom of the dispensing head 4 through the supporting plate 10, thereby heating the non-working dispensing head 4. It has the characteristics of simple structure and convenient operation.

[0035] In one or more embodiments, the bottom of the conical heater 11 has an opening, and the opening is connected to the interior of the conical heater 11 .

[0036] See also Figure 3 , Figure 4 The bottom of the conical heater 11 is provided with an opening, which can effectively prevent the glue liquid dripped into the conical heater 11 by the glue dispensing head 4 from accumulating, thereby reducing the number of cleaning times and improving the use effect of the present application.

[0037] In one or more embodiments, it also includes a scraping assembly configured on the carrier plate 10 and the conical heater 11, and the scraping assembly is used to scrape the glue adhered to the inner wall of the conical heater 11; the scraping assembly includes a driving gear 12 rotatably mounted on the carrier plate 10, a servo motor 13 driving the driving gear 12 to rotate, a driven gear 14 meshing with the driving gear 12 and located directly above the conical heater 11, and a scraper rod 15 connected to the driven gear 14 and attached to the inner wall of the conical heater 11.

[0038] See also Figure 2 , Figure 3 , Figure 4 The servo motor 13 is installed at the bottom of the carrier plate 10, and a through hole is provided on the driven gear for the glue dispensing head 4 to enter the conical heater 11. The servo motor 13 is used to drive the driving gear 12 to rotate, and then the driven gear 14 meshing with the driving gear 12 rotates. The driven gear 14 is coaxial with the conical heater 11. The driven gear 14 drives the scraper 15 to rotate on the inclined surface inside the conical heater 11 to scrape off the solidified glue attached to the inner surface of the conical heater 11, thereby improving the heating effect of the conical heater 11 on the glue dispensing head 4.

[0039] In one or more embodiments, the scraper bar 15 is tilted in the conical heater 11. This arrangement can facilitate the flow of the glue liquid in the conical heater 11, or reduce the pressure of the scraper bar 15 when rotating with the driven gear 14, thereby improving the scraping efficiency of the solidified glue in the conical heater 11.

[0040] In one or more embodiments, the inner wall of the conical heater 11 is sprayed with a polytetrafluoroethylene coating. It should be noted that polytetrafluoroethylene has a certain self-lubricating effect. Through the above arrangement, the possibility of the glue adhering to the inner surface of the conical heater 11 can be effectively reduced, and the heating effect of the conical heater 11 on the glue dispensing head 4 can be improved.

[0041] In one or more embodiments, a collecting box 16 is installed at the bottom of the carrier plate 10 below the conical heater 11. Figure 2 , Figure 3 The collecting box 16 is used to collect the glue liquid dripping from the conical heater 11, effectively preventing the glue liquid from dripping onto the frame 1 or the workpiece, reducing the contamination of the workpiece, and improving the use effect of the present application.
