[0002] A dispensing machine is an industrial device that uses automated control to precisely and evenly apply fluid materials such as glue, paint, and ink to designated locations on a product. It effectively replaces the inconsistencies that easily occur in manual operation and is one of the important pieces of equipment for achieving automated production in modern manufacturing. It is widely used in fields such as electronics, automobiles, medical devices, and LED manufacturing.

[0003] In dispensing operations, the existing dispensing solution involves directly installing a dispensing needle into the dispensing tube of the dispensing cylinder mounted on the dispensing fixture. This method cannot effectively control the extrusion rate, especially at the end of the glue line, where glue overflow is very likely to occur. This makes it impossible to accurately control the amount of glue dispensed at the end of the glue line, affecting the aesthetics and consistency of the glue line, leading to product defects and increasing subsequent processing costs.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1-3 As shown, in one embodiment, a dispensing and bonding control device includes: a dispensing cylinder 1 and a control valve 3.

[0032] The dispensing tube 1 is mounted on a fixed base 2 made of sheet metal. The fixed base 2 is a support formed by sheet metal processing and fits the shape of the dispensing tube 1, so that the dispensing tube 1 can be fixed on the dispensing machine through the fixed base 2. The two ends of the dispensing tube 1 are connected to the air supply end and the control valve 3 respectively through pipelines for conveying glue.

[0033] For example, one end of the dispensing cylinder 1 is provided with an air supply port for connecting to the air supply end, ensuring that no gas leakage occurs during transmission. The gas is then supplied through the air supply end to control the glue to flow out of the dispensing cylinder 1 at a preset flow rate and speed. Correspondingly, the other end of the dispensing cylinder 1 is connected to the control valve 3 through a Luer connector, ensuring the sealing and reliability of the connection and effectively preventing glue leakage during transmission. The other end of the control valve 3 is connected to the glue outlet tube 4 through a Luer connector, and the end of the glue outlet tube 4 is connected to the dispensing needle, so that the glue is accurately applied to the preset dispensing position of the product through the dispensing needle, ensuring the accuracy and quality of dispensing.

[0034] Please continue reading. Figures 1-3In this embodiment, the control valve 3 includes a first valve body 31 and a second valve body 32; wherein, the first valve body 31 is connected to the dispensing cylinder 1 and the dispensing tube 4 through pipelines respectively, and is used to guide the glue in the dispensing cylinder 1 to the dispensing tube 4; while the second valve body 32 is connected to an external air source through pipelines, and the control valve 3 is driven to operate by the air pressure of the external air source.

[0035] It should be noted that the first valve body 31 is provided with a flow channel shaft 33, and the first valve body 31 is rotatably connected to the second valve body 32 through the flow channel shaft 33. The flow channel shaft 33 is used to control the opening and closing of the glue flow channel.

[0036] For example, the first valve body 31 has a flow channel cavity 311 inside, which can provide a stable installation and rotation space for the flow channel shaft 33, and the flow channel shaft 33 passes through the flow channel cavity 311; correspondingly, the first valve body 31 has flow channel grooves 312 on both sides, and the flow channel grooves 312 are connected to the flow channel cavity 311.

[0037] For example, the cross section of the flow channel shaft 33 is a regular polygon, and the rotation angle of the flow channel shaft 33 is 0-90°; wherein, a flow channel hole 331 is provided in the middle of the flow channel shaft 33, and the flow channel hole 331 and the flow channel groove 312 are coplanar.

[0038] It is understandable that when the flow channel shaft 33 rotates to a specific angle, the flow channel hole 331 can precisely align with the flow channel groove 312, thus opening the glue flow channel; while when the rotation angle changes, the flow channel hole 331 and the flow channel groove 312 are misaligned, thus disconnecting the glue flow channel.

[0039] Furthermore, the flow channel 312 is equipped with a connecting joint 34, which is a Luer joint, characterized by convenient installation and removal and reliable sealing, effectively reducing the risk of glue leakage. Specifically, the connecting joint 34 includes a first joint 341 and a second joint 342: the first joint 341 is connected to the dispensing cylinder 1 and is used to introduce the glue in the dispensing cylinder 1 into the first valve body 31; while the second joint 342 is connected to the dispensing pipe 4, so that the glue is delivered to the dispensing pipe 4, and finally the dispensing operation is completed.

[0040] Please continue reading. Figures 1-3 In this embodiment, a control groove 321 is provided on one side of the second valve body 32. The inner contour of the control groove 321 fits with the outer contour of the flow channel shaft 33 to ensure that the flow channel shaft 33 will not wobble during rotation.

[0041] For example, an air supply connector 35 is installed on the outside of the second valve body 32. The air supply connector 35 is connected to an external air source through a pipeline. By switching different external air sources, the rotation of the control slot block 321 is realized, which in turn drives the flow channel shaft 33 to rotate, thereby completing the on / off adjustment of the glue flow channel.

[0042] It is understandable that the second valve body 32 can be a rotary cylinder (as prior art, the internal structure is not shown), which has the characteristics of fast response speed and high control precision.

[0043] Understandably, one set of the air supply connectors 35 of the second valve body 32 is connected to a normally open air source, and the other set is connected to a normally closed air source. Through the alternating operation of the two sets of air sources, the rotation angle of the rotary cylinder can be precisely controlled, thereby driving the flow channel shaft 33 to rotate within the range of 0-90°, and realizing precise on / off control of the glue flow channel.

[0044] Example 2:

[0045] See Figure 4 In another embodiment, a heating sleeve 5 may be selectively fitted on the outside of the dispensing cylinder 1 according to actual needs, and the heating sleeve 5 is electrically connected to the controller 6, which can precisely adjust the heating temperature of the heating sleeve 5.

[0046] Understandably, for adhesives with high viscosity, problems such as poor flow and uneven dispensing are likely to occur during the dispensing process. However, by controlling the heating temperature of the heating sleeve 5 through the controller 6, the adhesive can be heated to reduce its viscosity, maintain good fluidity, and thus ensure the smoothness of the dispensing process and the stability of the dispensing volume, effectively improving the dispensing quality.

[0047] Working principle:

[0048] Before the dispensing process begins, the heating temperature of the heating sleeve 5 can be controlled by the controller 6, thereby adjusting the viscosity of the adhesive in the dispensing tube 1 to a preset state.

[0049] When no dispensing is being performed, the normally open air source keeps the control block 321 of the second valve body 32 in its original position, so that the flow hole 331 of the flow shaft 33 is perpendicular to the flow groove 312 of the first valve body 31 at a 90° angle, thereby keeping the glue flow channel open. When the dispensing machine gives a dispensing start signal, the normally closed air source opens, causing the control block 321 of the second valve body 32 to rotate 90° clockwise, so that the flow hole 331 of the flow shaft 33 is aligned with the flow groove 312 of the first valve body 31, thereby keeping the glue flow channel open. When the dispensing machine gives a dispensing end signal, the normally closed air source closes, causing the control block 321 of the second valve body 32 to rotate 90° counterclockwise, so that the flow hole 331 of the flow shaft 33 is perpendicular to the flow groove 312 of the first valve body 31 at a 90° angle, thereby returning the glue flow channel to the open state, ultimately achieving rapid glue stoppage.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
