It is widely used in industries such as electronics, automotive, medical, LED, optics, and 3C products, especially in the assembly of electronic components, for dispensing, encapsulating, and bonding chips, screens, PCBs, and other parts.

[0003] When dispensing glue using a dispensing machine, it is usually done through a piezoelectric valve. However, the installation angle of the piezoelectric valve is fixed, which is not suitable for dispensing on conical or curved surfaces. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dispensing machine, comprising an organism, including:

[0005] The feeding module is used to transport materials.

[0006] The dispensing module is used to dispense adhesive onto materials.

[0007] The moving module is used to move the dispensing module along the X, Y, or Z axis;

[0008] The dispensing module includes a fixed frame, which is fixedly mounted on the movable module. The fixed frame is equipped with a swing cylinder and a piezoelectric valve, and the piezoelectric valve is rotatably connected to the swing cylinder.

[0009] Furthermore, it also includes:

[0010] The first connecting block is fixedly installed at the swing end of the swing cylinder;

[0011] The second connecting block is fixedly installed on one side of the piezoelectric valve;

[0012] The first connecting block and the second connecting block are detachably connected by screws.

[0013] Furthermore, including:

[0014] The guide post is fixedly installed on one side of the second connecting block;

[0015] A guide hole is formed on the first connecting block;

[0016] The guide post is matched with the guide hole.

[0017] Furthermore, at least two guide posts are provided, and the number of guide holes matches the number of guide posts.

[0018] Furthermore, it also includes:

[0019] A through hole is formed on the second connecting block;

[0020] A threaded hole is formed on the first connecting block;

[0021] When the guide post is inserted into the guide hole, the through hole corresponds to the threaded hole, and the axis of the through hole and the threaded hole forms a 90° angle.

[0022] Furthermore, it also includes a heating module, which comprises:

[0023] The heating frame is fixedly mounted on the machine body;

[0024] The heating element is fixedly mounted on the heating frame;

[0025] The air inlet is located above the heating element;

[0026] The air outlet is located below the heating element;

[0027] The air outlet of the heating tube corresponds to the feed inlet of the feeding module.

[0028] Furthermore, it also includes:

[0029] The testing frame is fixedly mounted on the machine body;

[0030] A temperature sensor, located at the lower end of the detection frame, is used to detect the temperature of the material.

[0031] The material passes through the feeding module and the heating module before reaching the bottom of the testing frame.

[0032] The beneficial effects of this utility model are as follows:

[0033] 1. By setting up a swing cylinder, the swing cylinder can control the piezoelectric valve to tilt according to the conical or curved surface of the material, so that the piezoelectric valve can match the irregular material and achieve a better dispensing effect. At the same time, by adding an industrial camera, the tilt angle can be automatically adjusted according to the material.

[0034] 2. The swing cylinder and the piezoelectric valve are detachably connected by a first connecting block and a second connecting block, which facilitates the inspection and maintenance of the swing cylinder or the piezoelectric valve through the detachable connection, and makes it convenient to repair or replace the swing cylinder or the piezoelectric valve.

[0035] 3. By setting two guide posts, the two guide posts and two guide holes achieve a positioning effect after insertion, preventing the first connecting block and the second connecting block from deflecting, so that the tilt angle is stable when the first connecting block drives the second connecting block to swing.

[0036] 4. By setting two guide posts, the two guide posts and two guide holes achieve a positioning effect after insertion, preventing the first connecting block and the second connecting block from deflecting, so that the tilt angle is stable when the first connecting block drives the second connecting block to swing.

[0037] 5. Since the axis of the through hole and the threaded hole is at a 90° angle, after the first connecting block and the second connecting block are fixed by screws, the angle between the guide post and the screw will be 90°, which can better prevent the first connecting block and the second connecting block from moving around, so that the connection between the first connecting block and the second connecting block is stable during use.

[0038] 6. By setting up a heating module, in practical applications, hot air can be connected to the air inlet of the heating tube through the air passage. The hot air enters the heating tube through the air inlet and is then blown out from the air outlet of the heating tube. The air outlet of the heating tube corresponds to the feed inlet of the feeding module, so that the hot air can heat the material when it is being transported in, resulting in better dispensing effect.

[0039] 7. By setting a temperature sensor, which can be an infrared temperature sensor, after the material passes through the heating module via the feeding module, it will reach the bottom of the detection frame. This allows the temperature sensor to detect the temperature of the heated material and transmit the data to the controller. The controller can then adjust the input power of the hot air according to the material temperature to achieve better performance. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0051] Example 1:

[0052] This embodiment provides a dispensing machine, including an organism 1, comprising:

[0053] The feeding module is used to transport materials.

[0054] The dispensing module is used to dispense adhesive onto materials.

[0055] The moving module is used to move the dispensing module along the X, Y, or Z axis;

[0056] The dispensing module includes a fixed frame 2, which is fixedly mounted on the movable module. The fixed frame 2 is equipped with a swing cylinder 3 and a piezoelectric valve 4, which are rotatably connected to the swing cylinder 3.

[0057] In this technical solution, the feeding module is a conveyor belt 17 installed inside the machine body 1. The material is input into the machine body 1 through the conveyor belt 17. The moving module is a three-axis slide table 18. The fixed frame 2 is installed on the Z-axis slide table of the three-axis slide table 18. The three-axis slide table 18 is driven by a drag chain and an external motor (not shown in the figure). The conveyor belt 17 and the three-axis slide table 18 are both existing technologies and will not be described in detail here.

[0058] The machine body 1 is equipped with an air passage (not shown in the figure) to provide power to the swing cylinder 3, thereby driving the swing cylinder 3 to swing, which in turn drives the piezoelectric valve 4 to tilt. The machine body 1 is also equipped with a controller (not shown in the figure) to adjust the rotation amplitude of the swing cylinder 3 and the stroke position of the three-axis slide table 18. When encountering materials with conical or curved surfaces, the swing cylinder 3 can be controlled to drive the piezoelectric valve 4 to tilt, thereby dispensing glue.

[0059] An industrial camera (existing technology, which will not be elaborated here) can also be installed on the mounting bracket 2 to identify materials with conical or curved surfaces. This allows for the pre-setting of templates and the control of the tilt angle of the piezoelectric valve 4 based on the material data identified by the industrial camera, thereby achieving better dispensing results.

[0060] Through this structural design, by setting up a swing cylinder 3, the swing cylinder 3 can control the piezoelectric valve 4 to tilt according to the conical or curved surface of the material, so that the piezoelectric valve 4 can match the irregularly shaped material and achieve a better dispensing effect. At the same time, by adding an industrial camera, the tilt angle can be automatically adjusted according to the material.

[0065] The second connecting block 6 is fixedly installed on one side of the piezoelectric valve 4;

[0066] The first connecting block 5 and the second connecting block 6 are detachably connected by screws.

[0067] With this structural design, the swing cylinder 3 and the piezoelectric valve 4 are detachably connected through the first connecting block 5 and the second connecting block 6, which makes it convenient to inspect the swing cylinder 3 or the piezoelectric valve 4 through the detachable connection, and to facilitate the maintenance and replacement of the swing cylinder 3 or the piezoelectric valve 4.

[0072] Guide hole 8 is formed on the first connecting block 5;

[0073] The guide post 7 is matched with the guide hole 8.

[0074] Through this structural design, the guide post 7 and guide hole 8 are set to guide the first connecting block 5 and the second connecting block 6 when they are docked, and at the same time, the fixed connection between the first connecting block 5 and the second connecting block 6 is stable.

[0077] Furthermore, at least two guide posts 7 are provided, and the number of guide holes 8 matches the number of guide posts 7.

[0078] Through this structural design, by setting two guide posts 7, the two guide posts 7 and the two guide holes 8 can play a positioning role after being inserted, preventing the first connecting block 5 and the second connecting block 6 from deflecting, so that the tilt angle is stable when the first connecting block 5 drives the second connecting block 6 to swing.

[0083] A threaded hole 10 is formed on the first connecting block 5;

[0084] When the guide post 7 is inserted into the guide hole 8, the through hole 9 corresponds to the threaded hole 10, and the axis of the through hole 9 and the threaded hole 10 forms an angle of 90°.

[0085] With this structural design, since the axis of the through hole 9 and the threaded hole 10 is at a 90° angle, after the first connecting block 5 and the second connecting block 6 are fixed by screws, the angle between the guide post 7 and the screw will be 90°, which can better prevent the first connecting block 5 and the second connecting block 6 from moving around, so that the connection between the first connecting block 5 and the second connecting block 6 is stable during use.

[0094] By incorporating a heating module, in practical applications, hot air can be connected to the air inlet 13 of the heating tube 12 through an air passage. The hot air enters the heating tube 12 through the air inlet 13 and is then blown out from the air outlet 14 of the heating tube 12. The air outlet 14 of the heating tube 12 corresponds to the feed inlet of the feeding module, so that the hot air can heat the material when it is being transported in, resulting in better dispensing effect.
