Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, specifically a gantry-type dispensing machine. Background Technology

[0002] In industrial production scenarios such as electronic component packaging, hardware fitting bonding, and plastic product sealing, dispensing is a key process to ensure product assembly accuracy and structural stability. As the core equipment for achieving automated dispensing, the gantry dispensing machine drives the dispensing structure to move precisely through multi-axis coordinated motion. It can apply glue to the designated position of the workpiece according to the preset path and dosage, effectively replacing manual dispensing, greatly improving dispensing efficiency and consistency, and meeting the needs of large-scale production for dispensing accuracy and capacity. Therefore, it has become an indispensable automated equipment in industries such as electronics, automobiles, and medical devices.

[0003] Traditional gantry dispensing machines have revealed numerous technical defects during long-term use: On the one hand, their X, Y, and Z axis transmission components mostly adopt a single-end supported lead screw structure, which is prone to deflection deformation due to the force on the cantilever of the lead screw, resulting in positional deviation when the dispensing structure moves. This is especially true when bearing heavy dispensing valves, directly affecting the dispensing quality of the product. On the other hand, traditional equipment lacks effective protection, and glue mist and dust generated during the dispensing process can easily penetrate the sliding rail and lead screw mating surfaces, causing accelerated wear of components. This not only shortens the service life of the transmission components and increases production downtime, but also makes it difficult to adapt to the needs of high-precision, long-term continuous production. Therefore, we have proposed a gantry dispensing machine. Utility Model Content

[0021] Working principle: When the device is working, the Y-axis motor housing 2 is started first, and its motor shaft drives the Y-axis lead screw 3 to rotate. Since the Y-axis nut block 7 is threadedly engaged with the Y-axis lead screw 3 and is constrained by the base 1, the Y-axis nut block 7 will move along the Y-axis direction, thereby driving the X-axis support 4 to move synchronously in the Y-axis direction, thus realizing the position adjustment of the dispensing structure 24 in the Y-axis direction. Then, the X-axis motor housing 12 is started, and its motor shaft drives the X-axis lead screw 13 to rotate. Since the X-axis nut block 14 is threadedly engaged with the X-axis lead screw 13 and is constrained by the X-axis support 4, the X-axis nut block 14 will move along the X-axis direction, thereby driving the Z-axis lead screw 24 to move synchronously in the Y-axis direction. The shaft support 5 moves synchronously in the X-axis direction to adjust the position of the dispensing structure 24 in the X-axis direction, thus determining the lateral base position for dispensing. Then, the motor in the Z-axis motor housing 19 operates, and the motor shaft drives the Z-axis lead screw 20 to rotate. The Z-axis nut block 21, due to its threaded connection with the Z-axis lead screw 20 and its restriction by the Z-axis support 5, moves along the Z-axis direction, thereby driving the dispensing support 6 and the dispensing structure 24 to rise and fall along the Z-axis. When the dispensing structure 24 moves with the dispensing support 6 to the appropriate X-axis and Z-axis positions, the dispensing structure 24 begins to work, performing dispensing operations on the workpiece placed on the base 1. The flexible baffle 11 and flexible baffle 18 can extend and retract synchronously with the movement of the device, without affecting the movement stroke, and can completely cover the openings of the Y-axis slide 8 and the X-axis slide 15. The internal transmission can prevent the internal parts of the device from being directly exposed to the external environment, avoiding transmission failure caused by the intrusion of foreign objects.
