AI Technical Summary
Existing gantry dispensing machines have low production efficiency and often produce product quality problems. This is mainly due to the slow movement speed caused by a single motor driving the gantry frame, severe motor overheating, and significant cantilever vibration.
The gantry is moved by dual linear motors, combined with a coreless linear motor, which reduces cantilever vibration and improves stability. The rigidity is enhanced by the U-shaped support structure of the base and the support plate design, which reduces the overall mass.
It achieves high-speed and precise dispensing, reduces cantilever sway, avoids damage to surrounding components by the motor, and improves structural stability and production efficiency.

DETAILED DESCRIPTION
[0025] In view of the low production efficiency of the existing gantry type glue dispensing machine, and the product quality problems often occur, the applicant has studied the structure of the existing gantry type glue dispensing machine, and found that: in view of the cost and debugging difficulty, the existing gantry type glue dispensing machine generally adopts a single motor to drive the gantry to move, and the single motor arranged on one side of the gantry not only bears the weight of the glue dispensing unit, but also bears the weight of the gantry, so the load is large, which leads to slow movement speed, low production efficiency and serious motor heating. Although a single high-power motor can be used to speed up the movement of the gantry and improve the production efficiency, in this way, the force on one side of the gantry is large, the thrust is unbalanced, the cantilever on the gantry vibrates, especially as the size of the workpiece and the glue dispensing range on the workpiece increase, the cantilever on the gantry also increases accordingly, the vibration becomes more obvious, and finally the glue dispensing unit on the gantry vibrates violently, thereby product quality problems occur, and the improvement of production efficiency and product efficiency become a contradictory option.
[0026] In view of the above-mentioned contradiction, the applicant proposes a gantry type glue dispensing machine, which adopts two linear motors respectively arranged on the left and right sides of the gantry to drive the gantry to move along the second direction Y, so that the forces on both sides of the gantry are balanced, thereby reducing the cantilever vibration. Further, the two linear motors adopt the existing coreless linear motor to reduce the damage to the surrounding parts caused by the excessive normal attraction generated by the core linear motor, and further improve the stability of the cantilever movement. The following is one of the specific embodiments of the gantry type glue dispensing machine of the present case:
[0027] Please refer to Figures 1 to 3 The present application provides a gantry type glue dispensing machine, which comprises a base 10, two drive motors 20, a gantry 30, a glue drawing unit 40 and an electrical unit 50. Among them, the two drive motors 20 are arranged on the two sides of the gantry 30 respectively, and the two drive motors 20 synchronously drive the gantry 30 to move along the second direction YY, and the glue drawing unit 40 slides along the first direction X on the gantry 30.
[0028] Please refer to Figure 4 The base 10 comprises a bottom plate 11, two side plates 12 and a support plate 13. The bottom plate 11 is parallel to the horizontal plane. The two side plates 12 are vertically arranged above the bottom plate 11. In the vertical direction, the two side plates 12 extend along the second direction Y, which is the direction of movement of the gantry 30. In the direction of the side plate 12, the bottom plate 11 and the two side plates 12 form a U-shaped support structure, which can provide sufficient stiffness support for the entire gantry type glue dispensing machine while reducing the overall weight. The support plate 13 is connected between the two side plates 12, and its surface is perpendicular to the surface of the bottom plate 11 and the side plate 12, thereby improving the structural strength. In this embodiment, the number of support plates 13 is two or more, and they are arranged in front of and behind the side plate 12 in the direction of the side plate 12. Preferably, a plurality of through holes 131 are formed in the support plate 13, and the plurality of through holes 131 are arranged in the horizontal direction from one side plate 12 to the other side plate 12 on the same support plate 13, so as to further reduce the overall weight. The two drive motors 20 are symmetrically arranged on the two side plates 12 respectively.
[0029] The drive motor 20 can be a linear motor in the prior art, the mover 22 moves along the horizontal direction, and when projected in the vertical direction, the sliding direction of the mover 22 is parallel to the second direction Y. Please refer to Figure 5In the embodiment, the driving motor 20 is a coreless linear motor, which comprises a stator 21, a mover 22 and a sliding groove 23.

The mover 22 is provided with a copper coil and is inserted into the sliding groove 23 and located between the two stators 21. The electrical unit 50 controls the energization of the mover 22. When the mover 22 is energized, the magnetic field generated between the stator 21 and the mover 22 interacts, thereby generating an electromagnetic thrust to push the mover 22 to slide along the sliding groove 23. Preferably, a flange 121 is protrudingly arranged on the outer side of the side plate 12, and the sliding groove 24 is arranged above the flange 121 and is supported thereby, so that the installation of the driving motor 20 is more stable.

[0031] The dispensing unit 40 is installed on the cantilever 34 and slides thereon between the two support columns 32, which comprises a bracket 41 extending in the vertical direction and a dispensing needle 42 sliding on the bracket 41. The bracket 41 slides along the cantilever 34, and the dispensing needle 41 moves up and down on the bracket 41 in the vertical direction to approach or move away from the workpiece.
[0032] The electrical unit 50 can be a power strip in the prior art for connecting with an external power supply for power supply, or can be a controller with a control circuit board for automatic control, etc. The electrical unit 50 is installed on the bottom plate 11 and projects in the vertical direction. The electrical unit 50 is located between the two side plates 12 and is close to one side of the sliding groove 23, and the support plate 13 is located on the other side of the sliding groove 23. The electrical unit 50 is concentratedly arranged to one end of the sliding direction of the mover 22, which can conveniently arrange the cable, connect the circuit and is convenient for subsequent addition of electrical modules or maintenance of electrical components. The electrical unit 50 is electrically connected with the driving motor 20 and the dispensing unit 40 respectively.
[0033] In operation, under the control of the electrical unit 50, the two movers 22 move synchronously in the sliding groove 23, driving the gantry 30 to move along the second direction Y, and the glue applying unit 40 moves along the cantilever 34 along the first direction X, and the glue applying needle 41 moves along the vertical direction in the support 41, so as to realize the movement of the glue applying needle 41 in three directions.
