[0002] A dispensing machine is an automated device used for precise control of fluid dispensing, and it is widely used in fields such as electronics manufacturing, automotive industry, and medical equipment.

[0003] Traditional dispensing machines have significant shortcomings when mixing multi-component adhesives. These devices typically employ a simple static mixing method, initially mixing two or more adhesive components before dispensing. This crude mixing process often results in uneven mixing of the adhesive components, incomplete reaction of the individual components, and ultimately affects the bonding performance after dispensing. Specifically, this manifests as incomplete curing of the adhesive, unstable bond strength, and decreased product yield. This technical deficiency severely restricts the application of dispensing technology in high-end manufacturing fields such as precision electronic packaging and microelectronic assembly.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] This utility model provides a dispensing machine, an automated device for precisely controlling fluid dispensing, widely used in electronics manufacturing, automotive industry, medical equipment and other fields. It includes: a base 1 with an internal through-hole and at least two feeding channels 101; a storage unit 2 installed at the bottom of the base 1, with an internal cavity 201 and a discharge port 202 at the bottom, communicating with the cavity 201; the feeding channels 101 communicating with the cavity 201; and the through-hole communicating with the cavity 201; and a stirring assembly 3 including a motor 301 and a stirring part 302. The motor 301 is installed at the top of the base 1, and the stirring part 302 is located inside the cavity 201. The output end of the motor 301 passes through the through-hole on the base 1 and connects to the stirring part 302.

[0026] The base 1 is a basic support structure used to support other auxiliary components; the feed channel 101 is used for the flow of adhesive components; the storage section 2 is used to store adhesive; and the stirring assembly 3 is used to stir the adhesive in the storage section 2.

[0027] In implementation, the motor 301 in the mixing assembly 3 is mounted on the base 1, and the output end of the motor 301 is passed through the through hole on the base 1. The mixing part 302 in the mixing assembly 3 is connected to the output end of the motor 301, so that the mixing part 302 is located at the bottom of the base 1 and the motor 301 is located at the top of the base 1. The storage part 2 is mounted at the bottom of the base 1, and the mixing part 302 is located in the cavity 201 of the storage part 2. After the storage part 2 is mounted on the base 1, the feeding channel 101 communicates with the cavity 201 of the storage part 2. Specifically, the feeding channel 101 has two openings on the base 1. One opening communicates with the cavity 201 of the storage part 2, and the other opening connects to an external feeding pipe. The adhesive component enters the feeding channel 101 from the external feeding pipe. In this embodiment, the base 1 includes two feeding channels 101, and the two feeding channels 101 are respectively connected to different... The feed pipe has two feed channels 101, each receiving different adhesive components. These two feed channels 101 are connected to the storage section 2. The adhesive components from the two different feed channels 101 enter the cavity 201. The motor 301 drives the stirring section 302 to rotate, stirring the two adhesive components flowing into the cavity 201 to ensure thorough mixing and form a specific adhesive. The adhesive flows out from the outlet 202, achieving dispensing. By feeding through two feed channels 101, which are connected to the storage section 2, and then mixing the different adhesive components through the stirring section 302 driven by the motor 301, the adhesive components are thoroughly mixed. The mixed adhesive is more uniform and reacts fully, ultimately achieving the desired bonding performance. Compared to static mixing in the prior art, the stirring mixing in this application ensures more thorough mixing of the adhesive components.

[0028] In some embodiments, the stirring unit 302 includes a rotating shaft 303, on which a first stirring blade 304, a second stirring blade 305, and a third stirring blade 306 are provided.

[0029] Among them, the rotating shaft 303 is the main rotary transmission mechanism, and the first stirring blade 304, the second stirring blade 305, and the third stirring blade 306 are three different shapes of stirring blades.

[0030] In practice, a first stirring blade 304, a second stirring blade 305, and a third stirring blade 306 are provided on the rotating shaft 303. The glue components entering the cavity 201 pass through the first stirring blade 304, the second stirring blade 305, and the third stirring blade 306 respectively. The glue components are thoroughly mixed by stirring with the three stirring blades.

[0031] Furthermore, the first stirring blade 304 is a disc-shaped stirring blade, the second stirring blade 305 is a spiral stirring blade, and the third stirring blade 306 is a sheet-shaped stirring blade. The first stirring blade 304, the second stirring blade 305, and the third stirring blade 306 are sequentially mounted on the rotating shaft 303 from top to bottom. The number of the first stirring blade 304 and the second stirring blade 305 is single, while the number of the third stirring blade 306 is multiple. The multiple third stirring blades 306 are distributed around the rotating shaft 303. The glue components first pass through the first stirring blade 304, which performs preliminary stirring to form a preliminary mixture. The second stirring blade 305 then performs secondary stirring to form a secondary mixture. The multiple stirring blades complete the final stirring to form the final mixture, resulting in the mixed glue. By stirring the glue components with stirring blades of different shapes, a progressive stirring is formed. The first stirring blade 304 and the second stirring blade 305 complete the preliminary stirring, and the third stirring blade 306 completes the fine stirring, making the glue components more effectively stirred and mixed.

[0032] In some embodiments, the output end of the motor 301 is connected to a connecting rod 307 via a coupling, and a bearing is provided in the through hole of the base 1. The connecting rod 307 passes through the bearing and is connected to the rotating shaft 303.

[0033] In practice, the output end of the motor 301 is connected to the connecting rod 307 via a coupling, and the connecting rod 307 is connected to the rotating shaft 303 via the bearing inside the shaft, thus completing the connection between the motor 301 and the rotating shaft 303. The motor 301 drives the rotating shaft 303 to rotate.

[0034] Furthermore, the rotating shaft 303 has a screw hole, and one end of the connecting rod 307 has an external thread. The connecting rod 307 is screwed into the screw hole of the rotating shaft 303 to form a detachable connection.

[0035] In some embodiments, a mounting base 102 is provided on the base 1, and the motor 301 is mounted on the mounting base 102.

[0036] In practice, a mounting base 102 is provided on the base 1, and a motor 301 is installed on the mounting base 102. The mounting base 102 serves as a connecting component between the motor 301 and the base 1, which can keep the motor 301 stable on the base 1.

[0037] In some embodiments, the mounting base 102 includes a first panel 103, a second panel 104, and a support cylinder 105. The first panel 103 is detachably connected to the base 1, the support cylinder 105 is mounted on the first panel 103, and the second panel 104 is mounted on the support cylinder 105.

[0038] In practice, the first panel 103 is detachably connected to the base 1, the support cylinder 105 is detachably connected to the first panel 103, and the second panel 104 is mounted on the support cylinder 105 to form a mounting base 102. A motor 301 is mounted on the second panel 104. The first panel 103 ensures the connection stability between the mounting base 102 and the base 1, and the second panel 104 ensures the connection stability between the mounting base 102 and the motor 301. The support cylinder 105 constitutes an overall support structure, so that the first panel 103 and the second panel 104 remain stable.

[0039] Furthermore, the first panel 103 and the second panel 104 are provided with through holes. The through holes on the first panel 103, the second panel 104, and the base 1 are all on the same axis. The output end of the motor 301 passes through the through hole on the second panel 104, the interior of the support cylinder 105, the through hole on the first panel 103, and the through hole on the base 1 to connect with the stirring part 302. The support cylinder 105 can also accommodate the internal structure of the output end of the motor 301. The first panel 103 is connected to the base 1 by screws, the support cylinder 105 is connected to the first panel 103 by screws, and the support cylinder 105 is connected to the second panel 104 by screws. In some cases, the first panel 103, the support cylinder 105, and the second panel 104 can also be connected by snap-fit.

[0041] In practice, a piston rod 107 is installed in the branch channel 106, and a cylinder 108 is connected to the piston rod 107. The cylinder 108 drives the piston rod 107 to move in the branch channel 106. By moving the piston rod 107 in the branch channel 106, the internal pressure is changed, thereby controlling the flow of adhesive components in the feeding assembly and ultimately controlling the discharge of adhesive.

[0042] Furthermore, the cylinder 108 is mounted on the base 1 via a base with a through hole. The output end of the cylinder 108 passes through the through hole and connects to the piston rod 107. In this embodiment, two feeding channels 101 are provided, each with a branch channel 106. Each branch channel 106 contains a piston rod 107, and each piston rod 107 is connected to a cylinder 108. This allows for control of the output of adhesive components on each feeding channel 101.

[0043] In some embodiments, the storage section 2 includes a material cylinder 203 and a bottom cover 204. The material cylinder 203 and the bottom cover 204 are detachably connected. The cavity 201 is located inside the material cylinder 203, and the discharge port 202 is located on the bottom cover 204.

[0044] Among them, the material cylinder 203 is the main material storage part, the bottom cover 204 is used to close the material cylinder 203, and the bottom cover 204 has a discharge port 202 for the output of glue.

[0045] During implementation, the material cylinder 203 is connected to the base 1, the adhesive components are stirred and mixed in the material cylinder 203, and then flow out through the outlet 202 on the bottom cover 204 to achieve dispensing.

[0046] Furthermore, the bottom surface inside the bottom cover 204 has a funnel-shaped structure with a discharge port 202 in the center. The funnel-shaped bottom surface makes it easier for the glue to flow out.

[0047] In some embodiments, the base 1 has a connector 109 at its bottom, and the barrel 203 is detachably sleeved on the connector 109.

[0048] During implementation, the material cylinder 203 is detachably connected to the connector 109, so that the material cylinder 203 is fixed at the bottom of the base 1. The detachable connection makes it easy to remove the material cylinder 203 and clean it.

[0049] Furthermore, the through hole of the base 1 and the opening of the feed channel 101 on the base 1 are both located at the bottom of the connector 109. The inside of the barrel 203 is provided with internal threads, and the outside of the connector 109 is provided with external threads. The barrel 203 and the connector 109 are connected by threads.

[0050] In some embodiments, the sides of both ends of the barrel 203 are provided with annular flanges 205, and the barrel 203 is sleeved on the outer cylinder 206. The side wall of the outer cylinder 206, the annular flanges 205, and the side wall of the barrel 203 together form a cooling space 207. The outer cylinder 206 is provided with a water inlet 209 and a water outlet 208.

[0051] In practice, the outer cylinder 206 is fitted over the material cylinder 203. Since the sides of both ends of the material cylinder 203 are provided with annular flanges 205, when the outer cylinder 206 is fitted over the material cylinder 203, the side wall of the outer cylinder 206, the annular flanges 205, and the side wall of the material cylinder 203 together form a cooling space 207. Coolant enters through the inlet 209 of the outer cylinder 206 and exits through the outlet 208. An external coolant circulation and recovery mechanism is provided, and the coolant fills the cooling space 207 to dissipate heat from the material cylinder 203.
