Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to a visual positioning module for an automatic adhesive application device. Background Technology

[0002] A glue gun is a device used to spray or inject adhesive onto the surface of an object under pressure. Traditional hot melt glue guns use high-pressure air to open and close the valve needle and the glue inlet of the copper head, controlling the glue dispensing and stopping. Adjusting the height of the adjusting rod, which is threaded onto the rear cover, controls the opening size of the valve needle and the glue inlet of the copper head, thus controlling the glue dispensing amount. However, existing glue guns do not allow users to have a precise aiming position, leading to errors between the aiming position and the seen position. This makes it difficult for users to accurately aim at the coating, reducing the accuracy of glue application and consequently reducing work efficiency. It is also unsuitable for accurately applying glue to irregular coatings. Furthermore, existing devices cannot freely adjust the spray rate, which is detrimental to practical use. With technological advancements, equipment is becoming increasingly intelligent, and the cost of intelligent equipment is decreasing. Therefore, intelligent methods can be adopted to solve the technical problems of manual glue application.

[0003] One of the challenges in upgrading equipment to be intelligent is how to accurately identify the boundaries of objects and fit those boundaries so that the equipment can apply adhesive precisely. Utility Model Content

[0004] The purpose of this invention is to provide a visual positioning module for an automatic glue application device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An automatic glue-applying device visual positioning module includes a glue applicator, a control cabinet for the glue applicator, a support rod on top of the glue applicator, a servo motor on top of the support rod, a light source fixedly mounted on the output shaft of the servo motor, a light-transmitting cover on the outside of the light source, a fixed baffle on top of the glue applicator, a camera fixedly mounted on top of the fixed baffle, and the light-transmitting cover including an arc-shaped plate, a connecting rod, a telescopic rod, and a transparent plate. The arc-shaped plate is hinged to the light source, one end of the connecting rod is hinged to the top of the support rod, the other end of the connecting rod is hinged to one end of the telescopic rod, the end of the telescopic rod not connected to the connecting rod is hinged to the arc-shaped plate, and the transparent plate is fixedly mounted on the bottom end of the arc-shaped plate.

[0007] By adopting the above technical solution, when supplemental lighting is needed, the light intensity can be adjusted according to the reflectivity of the workpiece surface to be coated. If the reflectivity of the material surface to be coated is high, and the position and intensity of the light source remain unchanged, the position of the transparent plate can be changed by the telescopic rod, connecting rod and arc plate to block the light source and the workpiece to be coated, thereby weakening the light intensity. Compared with direct light, the light can be softened by the blocking of the transparent plate, avoiding large light spots on the surface of highly reflective materials, which would lead to visual recognition failure.

[0008] In a further embodiment, the transparent plate is an annular plate, and a through groove is provided on one side of the transparent plate.

[0009] In a further embodiment, the support rod includes an outer circular rod and an inner circular rod, the top of the outer circular rod is provided with a shaft hole, and the bottom end of the inner circular rod is slidably installed in the shaft hole.

[0010] In a further embodiment, a cylinder is provided at the bottom of the shaft hole, and the bottom end of the inner round rod is fixedly connected to the drive rod of the cylinder. The cylinder is used to drive the inner round rod to slide up and down in the shaft hole.

[0011] In a further embodiment, a proximity alarm is provided on the top of the glue applicator.

[0012] In a further embodiment, a suction pipe is provided at the top periphery of the glue applicator.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When supplemental lighting is needed, the light intensity can be adjusted according to the reflectivity of the workpiece surface to be coated. If the reflectivity of the material surface to be coated is high, and the position and intensity of the light source remain unchanged, the position of the transparent plate can be changed by the telescopic rod, connecting rod and arc plate to block the light source and the workpiece to be coated, thus weakening the light intensity. Compared with direct light, the light can be softened by the blocking of the transparent plate, avoiding large light spots on the surface of highly reflective materials, which would lead to visual recognition failure.

[0020] Example 1:

[0021] like Figures 1-2As shown, an automatic glue-applying device visual positioning module includes a glue applicator 1, a control cabinet 2, a support rod 3 on top of the glue applicator 1, a servo motor 4 on top of the support rod 3, a light source 5 fixedly mounted on the output shaft of the servo motor 4, a light-transmitting cover 6 on the outside of the light source 5, a fixed baffle 7 on top of the glue applicator 1, and a camera fixedly mounted on the top of the fixed baffle 7. The light-transmitting cover 6 includes an arc-shaped plate 61, a connecting rod 62, a telescopic rod 63, and a transparent plate 64. The arc-shaped plate 61 is hinged to the light source 5. One end of the connecting rod 62 is hinged to the top of the support rod 3, and the other end of the connecting rod 62 is hinged to one end of the telescopic rod 63. The end of the telescopic rod 63 not connected to the connecting rod 62 is hinged to the arc-shaped plate 61. The transparent plate 64 is fixedly mounted. The transparent plate 64 is a ring-shaped plate with a through groove on one side. The support rod 3 includes an outer rod and an inner rod. The top of the outer rod has a shaft hole, and the bottom of the inner rod is slidably installed in the shaft hole. A cylinder is installed at the bottom of the shaft hole, and the bottom of the inner rod is fixedly connected to the drive rod of the cylinder. The cylinder is used to drive the inner rod to slide up and down in the shaft hole. The top of the glue applicator 1 is equipped with a proximity alarm, and the top periphery of the glue applicator 1 is equipped with a suction pipe. The light-emitting surface of the light source has a certain area. When supplemental lighting is needed, the light-emitting surface is aligned with the workpiece placed on the worktable. Then, it is manually determined whether a transparent plate needs to be placed to disperse the light. If dispersion is needed, the transparent plate is driven by a telescopic rod to block the light. The telescopic rod is a manually adjustable telescopic rod.

[0022] Specific implementation process: When supplemental lighting is needed, the light intensity can be adjusted according to the reflectivity of the workpiece surface to be coated. If the reflectivity of the material surface to be coated is high, and the position and intensity of the light source remain unchanged, the position of the transparent plate is changed by the telescopic rod, connecting rod and arc plate, blocking the light source between the light source and the workpiece to be coated, thus weakening the light intensity. Compared with direct light, the light can be softened by the blocking of the transparent plate, avoiding large light spots on the surface of highly reflective materials, which would lead to visual recognition failure.

[0023] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
