Description

Technical Field

[0001] This utility model belongs to the technical field of dispensing equipment, and in particular relates to a coating machine. Background Technology

[0002] A coating machine, also known as an adhesive applicator, glue sprayer, or oil sprayer, is an automated mechanical device that controls and coats fluids onto the surface of a product. The coating machine applies a new material to the product surface, providing excellent waterproofing, dustproofing, and anti-static properties. With the increasing demands for circuit board stability in the electronics industry, conformal coating machines have become an indispensable part of electronic product manufacturing. By coating circuit boards with a conformal coating machine, moisture-proofing, dustproofing, and corrosion-proofing effects can be achieved.

[0003] Existing coating machines are equipped with structures for cleaning the dispensing head. However, the dispensing head is usually cleaned only once, and the product is immediately dispensed after cleaning. If the dispensing head is not cleaned properly, it can easily lead to uneven dispensing. Although cameras are usually used to inspect the dispensing products, if the dispensing is not up to standard, the circuit board will be scrapped, thus increasing production costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0041] In one embodiment of this utility model, such as Figures 1-5 As shown, a coating machine includes:

[0042] Workbench 10;

[0043] The moving module 20 is mounted on the worktable 10. The moving module 20 includes a first moving component that moves along the X-axis, a second moving component that moves along the Y-axis, and a third moving component that moves along the Z-axis, which are connected in sequence.

[0044] The dispensing module 30 is mounted on the third moving component and includes a dispensing head 31 and a camera 32.

[0045] A dispensing head cleaning rack is installed on the workbench 10 and located to the side of the movable module 20;

[0046] The detection component is set on the workbench 10 and configured to pre-dispense adhesive into the dispensing module 30 after cleaning.

[0047] A cleaning component is disposed on the workbench 10 and configured to clean the pre-applied adhesive areas.

[0048] Specifically, the dispensing head 31 and the camera 32 are both mounted on the third moving component. The first moving component, the second moving component, and the third moving component drive the dispensing head 31 and the camera 32 to move in different directions, respectively. The dispensing head cleaning rack is used to clean the dispensing head 31. After cleaning, the dispensing head 31 is pre-dispensed on the detection component. The camera 32 detects the condition of the pre-dispensed glue. If the glue condition is found to be uniform, it indicates that the dispensing head 31 is cleaned successfully. If the camera 32 detects that the amount of glue in the pre-dispensed glue is unqualified, the moving module 20 drives the dispensing head 31 to clean it again. By setting the detection component, pre-dispensing can be performed before dispensing the product to detect the cleanliness of the dispensing head 31, preventing the dispensing head 31 that is not cleaned successfully from dispensing the product, thereby reducing product scrap. In addition, this embodiment also provides a cleaning component, which is used to automatically clean the pre-dispensed glue, reducing manual operation and improving the degree of automation.

[0049] Furthermore, the dispensing head cleaning rack includes a frame and a container mounted on the frame. The container is filled with cleaning fluid. The frame can be mounted on the workbench 10 or on other equipment adjacent to the workbench 10. After the dispensing head 31 has been used for a certain period of time or a certain number of times, it will be moved to the container for cleaning to avoid clogging of the dispensing head 31.

[0050] In another embodiment of this utility model, such as Figures 1-4 As shown, the detection component includes a detection tank 41, and a water outlet 42 is provided on one side of the bottom of the detection tank 41.

[0051] The cleaning assembly includes a rinsing component 51, which is configured to rinse the pre-dispensed adhesive. Specifically, after the dispensing head 31 pre-dispenses adhesive at the bottom of the detection tank 41, the rinsing component 51 rinses the adhesive, and the rinsed wastewater flows out through the outlet hole 42, thereby keeping the detection tank 41 clean for the next pre-dispensing by the dispensing head 31 and improving the accuracy of the detection.

[0052] In another embodiment of this utility model, such as Figures 1-4 As shown, the flushing component 51 includes a mounting bracket and a water outlet component. The water outlet component can be a water pipe. The mounting bracket is equipped with a mounting component that is compatible with the water outlet component. The mounting component can be a structure for fixing the water pipe, such as a fixing clamp, which will not be described in detail here.

[0053] In another embodiment of this utility model, the detection component further includes a weighing element, which is disposed below the detection groove 41. Specifically, by disposing of a weighing element below the detection groove 41, the amount of glue pre-dispensed is weighed to cooperate with the detection by the camera 32 and improve the accuracy of glue dispensing volume detection by the dispensing head 31.

[0054] In another embodiment of this utility model, such as Figure 4 As shown, the bottom of the detection tank 41 includes a first bottom 411 and a second bottom 412. The first bottom 411 is higher than the second bottom 412, and the water outlet 42 is located on the second bottom 412. Specifically, because the first bottom 411 is higher than the second bottom 412, the flushed wastewater easily flows through the second bottom 412 and out through the water outlet 42, further improving the cleanliness of the detection tank 41.

[0055] In another embodiment of this utility model, such as Figure 4 As shown, the second tank bottom 412 is located around the first tank bottom 411; each of the second tank bottoms 412 is provided with a water outlet 42, so that the sewage located at the first tank bottom 411 can flow to the second tank bottom 412 in any direction.

[0056] In another embodiment of this utility model, such as Figures 1-4 As shown, at least one side of the detection tank 41 is provided with an air outlet 43. Specifically, the air outlet 43 can blow air to dry the bottom of the detection tank 41, so that the bottom of the detection tank 41 is dry when the dispensing head 31 pre-dispenses adhesive next time, thus avoiding the influence of water on the pre-dispensing detection.

[0057] Furthermore, the air outlet 43 is connected to an air supply device, which can be a blower.

[0058] In another embodiment of this utility model, a drying element is provided at the bottom of the detection groove 41. Specifically, the drying element is a heating element, which may be a heating wire or the like embedded in the bottom of the detection groove 41.

[0059] In another embodiment of this utility model, such as Figure 5 As shown, the detection component includes a positioning element 61 and a detection plate, with the detection plate disposed on the positioning element 61;

[0060] The cleaning assembly includes a cleaning tank 71 and a suction member 81. The cleaning tank 71 contains cleaning fluid, and the suction member 81 is positioned between the positioning member 61 and the cleaning tank 71. The suction member 81 is configured to transfer the detection plate between the positioning member 61 and the cleaning tank 71. Specifically, the suction member 81 places the detection plate on the positioning member 61, and the dispensing head 31 pre-dispenses adhesive onto the detection plate. After pre-dispensing, the suction member 81 transfers the detection plate from the positioning member 61 to the cleaning tank 71. Since the cleaning tank 71 contains cleaning fluid, it can dissolve and clean the adhesive on the detection plate. After cleaning, the suction member 81 transfers the detection plate from the cleaning tank 71 back to the positioning member 61, thereby keeping the detection plate clean before each pre-dispensing to improve the detection accuracy of pre-dispensing.

[0061] In another embodiment of this utility model, an ultrasonic cleaner is provided in the cleaning tank 71. Specifically, providing an ultrasonic cleaner in the cleaning tank 71 can improve the cleaning effect. Furthermore, ultrasonic cleaners are existing technology and will not be described in detail here. This embodiment uses them in the cleaning tank 71 to enhance the cleaning degree of the detection plate.

[0062] In another embodiment of this invention, at least a portion of the detection plate is made of magnetic material, and the suction member 81 is provided with a magnetic adsorption head. Specifically, the magnetic adsorption transfer of the detection plate is simple in structure and avoids the influence of the cleaning liquid in the cleaning tank 71 on the suction member 81 during the transfer process.

[0063] In another embodiment of this utility model, such as Figure 5 As shown, the positioning member 61 includes two fixed plates 611 and two movable plates 612. The two fixed plates 611 are configured to limit the adjacent sides of the detection plate, and the two movable plates are configured to limit the other two sides of the detection plate. This allows it to be used with detection plates of different sizes, improving its versatility.

[0064] In another embodiment of this utility model, a water outlet 42 is provided at the bottom of the positioning member 61. Specifically, the water outlet 42 allows cleaning fluid remaining on the detection plate to flow out, thereby reducing contamination of the workbench 10.

[0065] In another embodiment of this utility model, the detection component further includes a weighing component, which is disposed below the positioning component 61. Specifically, by disposing of a weighing component below the positioning component 61, the amount of glue pre-dispensed is weighed to cooperate with the detection of the camera 32 and improve the accuracy of glue dispensing volume detection of the dispensing head 31.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
