Description

Technical Field

[0001] This utility model relates to the field of equipment technology, and in particular to an automatic dispensing device. Background Technology

[0002] A dispensing machine, also known as an adhesive applicator, glue applicator, glue applicator, or glue dispensing machine, is a specialized machine for controlling fluids. It's an automated machine that dispenses or coats fluids onto the surface or interior of a product, enabling three-dimensional and four-dimensional dispensing with precise positioning, accurate glue control, and preventing stringing, leakage, or dripping. Dispensing machines are primarily used in product manufacturing processes to precisely dispense, inject, coat, or drip adhesives, paints, and other liquids onto specific locations on each product. They can be used to create dots, lines, circles, or arcs. Automated equipment replaces manual labor, enabling mechanized production and significantly reducing labor and production costs. Furthermore, it can be operated as a standalone unit, offering simplicity, convenience, high speed, and precision, effectively improving dispensing quality.

[0003] However, because the adhesive is liquid during dispensing, residue remains on the nozzle of the dispensing gun after dispensing, resulting in a relatively thick adhesive layer initially formed. Since the adhesive layer is generally thin, the difference is difficult to observe with the naked eye. Therefore, after the dispensing process, the workpiece needs to be placed in additional high-precision inspection equipment for thickness measurement, increasing production steps and reducing production efficiency. Therefore, it is necessary to propose a new solution to address these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide an automatic dispensing device that can effectively solve the problem that existing dispensing devices require additional high-precision detection equipment to detect the thickness of the workpiece after dispensing, which leads to increased production steps and reduced production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic dispensing device includes a machine table, a turntable, a left-right moving device, a front-back moving device, a vertical moving device, and a dispensing gun.

In this embodiment, there are multiple fixtures 21, which are arranged circumferentially at intervals around the periphery of the turntable 20.

[0038] The left-right moving device 30 is mounted on the bracket 12 and connected to the control module. In this embodiment, the left-right moving device 30 includes a first driving mechanism 31, a first guide rail 32, and a first slider 33. The first driving mechanism 31 is mounted on the bracket 12. The first guide rail 32 extends left and right and is mounted on the first driving mechanism 31. The first slider 33 is movably mounted on the first guide rail 32 and is driven to move left and right by the first driving mechanism 31. The aforementioned front-back moving device 40 is mounted on the first slider 33.

[0039] The forward and backward moving device 40 is movably mounted on the left and right moving device 30 and is driven by the left and right moving device 30 to move back and forth. The forward and backward moving device 40 is connected to the control module. In this embodiment, the forward and backward moving device 40 includes a second driving mechanism 41, a second guide rail 42 and a second slider 43. The second driving mechanism 41 is mounted on the left and right moving device 30. The second guide rail 42 extends forward and backward and is mounted on the second driving mechanism 41. The second slider 43 is movably mounted on the second guide rail 42 and is driven by the second driving mechanism 41 to move left and right. The aforementioned up and down moving device 50 is mounted on the second slider 43.

[0040] The up-and-down moving device 50 is movably mounted on the front-and-back moving device 40 and is driven by the front-and-back moving device 40 to move back and forth. In this embodiment, the up-and-down moving device 50 includes a third driving mechanism 51, a third guide rail 52, and a third slider 53.

[0041] The glue gun 60 is movably mounted on the vertical moving device 50 and is driven to move up and down by the vertical moving device 50. The glue gun 60 is connected to the control module.

[0042] Furthermore, it includes a camera 70, which is fixedly mounted at the front end of the front and rear moving device 40 and connected to the control module.

[0043] The working principle of this embodiment is described in detail below:

[0044] First, the operator places the workpiece into slot 211 of fixture 21. At this time, fixture 21 is located below the first infrared scanner 13. The first infrared scanner 13 scans and models the workpiece to obtain a model before dispensing. Then, turntable 20 rotates, and fixture 21 moves to the side of camera 70. The front of the workpiece has inconspicuous markings printed on it. The camera takes pictures of fixture 21 and workpiece and analyzes whether the workpiece is facing up. Subsequently, turntable 20 continues to rotate, and fixture 21 moves to the side of dispensing gun 60. The left-right moving device 30, the front-back moving device 40, and the up-down moving device 50 drive dispensing gun 60 to move. Dispensing gun 60 first moves to the right, so that the nozzle of dispensing gun 60 contacts the upper edge of scraper 16. After the residual glue on the nozzle of dispensing gun 60 is scraped away, dispensing begins. After dispensing is completed... The glue gun 60 is reset, and during the reset, the nozzle of the glue gun 60 will contact the upper edge of the scraper 16 again. After the glue residue on the nozzle of the glue gun 60 is scraped away, the turntable 20 continues to rotate, and the fixture 21 moves to the lower part of the second infrared scanner 14. The second infrared scanner 14 scans and models the workpiece to obtain the model after glue dispensing. The control module then calculates the thickness of the glue layer. The workpiece of this utility model is a ceramic heat sink. In order to improve the heat dissipation effect, thin ribs are protruding on the ceramic sheet. When in use, they form through grooves to promote air flow, thereby increasing the heat exchange efficiency with the air and improving heat dissipation. However, these ribs are easily misidentified as strip-shaped glue layers. Therefore, this utility model adopts the design of two infrared scanners to avoid the ribs being misidentified as strip-shaped glue layers.

[0045] The key design feature of this utility model is:

[0046] By positioning the first infrared scanner above the front of the working plane and the second infrared scanner above the right side of the working plane, after the workpiece is placed in the fixture, the first infrared scanner scans and models the workpiece before dispensing, obtaining the model before dispensing. After dispensing, the turntable rotates, causing the fixture to move to the second infrared scanner, where it is scanned and modeled, obtaining the model after dispensing. The control module then calculates the thickness of the adhesive layer, and the detection is completed at the time of material discharge, eliminating the need for an additional thickness detection step. This reduction in processes effectively improves production efficiency.

[0047] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
