Embodiment 1

[0029] Such as Figure 1-Figure 9 As shown, the present invention provides a kind of dispensing machine, frame 1, support frame 2 and dispensing mechanism 3, in the present embodiment, frame 1 comprises movable bearing plate 11, and support frame 2 comprises air pressurizer 21 , the dispensing mechanism 3 includes a dispensing head 31 and a needle 32, the dispensing head 31 includes a spray needle 311, a colloid stop block 312 and a colloid chamber 313, the outer wall of the lower end of the spray needle 311 is provided with a screw thread 314, and the bottom of the spray needle 311 adopts The semicircular groove is set. When in use, place the substrate to be dispensed on the movable carrier plate 11, open the air pressurizer 21 to pressurize the colloid chamber 313, the glue liquid is filled in the colloid chamber 31, and the spray needle 311 is in the Under the action of the spring force, it moves downward, the spherical surface at the end of the spray needle 311 collides wi...

Embodiment 2

[0033] Such as Figure 7 As shown, on the basis of Example 1, the present invention provides a technical solution: a first partition b1 is provided inside the metal soft board a1, and the first partition b1 is arranged in multiple layers, and each layer of the first partition Each b1 is provided with an elastic ball b2 correspondingly, and the vibration of the elastic soft board a2 drives the elastic ball b2 inside the metal soft board a1 to collide in the cavity separated by the first partition b1.

Embodiment 3

[0035] Such as Figure 5As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: preferably, a second partition c3 is provided in the middle of the first barrier block a3, and the upper end of the second partition c3 is provided There is a ball c4, the outer wall of the center side of the first barrier block a3 is provided with an elastic block c1, and the inner wall of the elastic block c1 is fixedly connected with a second spring c2, and the elastic block c1 is set on an outer convex arc surface, and its collision resilience is greater. The outer wall on the other side of the center of the first barrier block a3 is set with an indented arc surface, wherein, when the elastic soft plate a2 is reset, one end of the elastic soft plate a2 and the outer wall on the other side of the center of the first barrier block a3 are indented. Contact, small barrier, easy reset.

Abstract

The invention discloses a dispensing machine, which relates to the technical field of fluid dispensing equipment and comprises a rack, a support frame and a dispensing mechanism, wherein the rack comprises a movable bearing plate, the support frame comprises an air pressurizer, the dispensing mechanism comprises a dispensing head and a needle head, the dispensing head comprises a spray needle, a colloid limiting block and a colloid chamber, and the outer wall of the lower end of the spray needle is provided with a thread; and the bottom of the spray needle is provided with a semicircular groove. By adopting the combination of the connecting block and the second cavity, after dispensing work is finished, due to the principle of thermal expansion and cold contraction, glue liquid generates outward tension on a metal soft plate in the condensation process in the dispensing head, and vibration is generated in the second cavity, so that a gap is generated between the cooled glue liquid and the metal soft plate; and after the glue liquid is solidified, the needle head is pushed upwards from the bottom of the needle head, so that a connecting block applies extrusion force to the solidified glue liquid on the upper layer to accelerate the falling of the glue, namely, the dispensing head can continue to work only by replacing the needle head and the connecting block, and thus, the waste of a dispensing head shell is reduced.

Description

technical field [0001] The invention relates to a dispensing device, relates to the technical field of fluid dispensing equipment, and in particular to a dispensing machine. Background technique [0002] Glue dispensing machine, also known as glue applicator, glue filling machine, glue machine, etc., is an automatic machine that controls fluid and drips, coats, and pots liquid on the surface of the product or inside the product. The glue dispenser is mainly used for accurate pointing, pouring, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. [0003] Fluid jet dispensing is a recently developed dispensing technology. Its basic principle is similar to that of an inkjet printer, and the material can be separated automatically by applying a large enough force to the fluid. The glue liquid fills the gap between the spray needle and the syrin...
