Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to 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. Utility Model Content

[0003] The purpose of this invention is to provide an automatic glue application device to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An automatic glue application device includes a worktable, a control cabinet located on one side of the bottom of the worktable for controlling the worktable, a limit rail on the top of the worktable, a slider slidably mounted on the top of the limit rail, a crossbar fixedly mounted on the top of the slider, the crossbar extending in the front-back direction, a gap between the bottom surface of the crossbar and the top surface of the worktable, linear drive motors symmetrically arranged at the bottom of the crossbar, fixing blocks fixedly mounted on the drive shafts of the linear drive motors, nozzles fixedly mounted on the fixing blocks, a traveling drag chain fixedly mounted on the top of the crossbar, the traveling drag chain containing wiring harnesses and pipes, a liquid storage tank at the bottom of the worktable, the pipes connecting the nozzles and the liquid storage tank, the wiring harness providing electrical signal connection between the nozzles, the liquid storage tank, and the worktable, and an infrared rangefinder at the bottom of each nozzle.

[0006] By adopting the above technical solution, the linear drive motor drives the nozzle to slide back and forth on the crossbar, and the crossbar can be moved left and right by the slider on the limit rail at the top of the worktable. This realizes the initial automated control of the nozzle in the key part of the spraying equipment. By using an infrared rangefinder installed at the bottom of the nozzle, the boundary of the workpiece located at the top of the worktable can be scanned. Because the workpiece has thickness, the distance data measured by the infrared rangefinder will decrease sharply when the nozzle passes through and reaches the surface of the workpiece, thereby realizing automatic spraying of workpieces with different boundaries.

[0007] In a further embodiment, the top of the workbench is provided with a plurality of threaded grooves, and a screw is screwed into each of the threaded grooves.

[0008] By adopting the above technical solution, when it is necessary to place a workpiece on the surface of the worktable, some of the screws can be rotated so that their top surfaces are higher than the top surfaces of the worktable. This is used to elevate the thin sheet when spraying it, making it easier for the infrared rangefinder to read and identify it.

[0009] In a further embodiment, the top surface of the screw is provided with a groove, and the surface of the worktable is provided with grid lines.

[0010] By adopting the above technical solution, multiple screws can be quickly rotated to the same height by aligning the grid lines with the engraved grooves.

[0011] In a further embodiment, a laterally driven telescopic cylinder is provided on both the left and right sides of the top of the workbench. A baffle is fixedly installed on the top rod of the telescopic cylinder, and the telescopic cylinder is used to move the baffle closer to / away from the center of the workbench.

[0012] In a further embodiment, the limiting slide rail is a linear drive pneumatic guide rail.

[0013] In a further embodiment, support rods are provided at the four corners of the top of the workbench, and a top plate is fixedly installed on the top of the support rods.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The nozzle is driven by a linear drive motor to slide back and forth on a crossbar. The crossbar can be moved left and right by a slider on a limit rail at the top of the worktable. This achieves the initial automated control of the nozzle, a key part of the spraying equipment. An infrared rangefinder installed at the bottom of the nozzle can scan the boundary of the workpiece located at the top of the worktable. Because the workpiece has thickness, the distance measured by the infrared rangefinder will decrease sharply when the nozzle passes over the workpiece surface. This achieves the effect of automatic spraying of workpieces with different boundaries. Attached Figure Description

[0020] Example 1:

[0021] like Figure 1As shown, an automatic glue application device includes a workbench 1. A control cabinet 2 is installed on one side of the bottom of the workbench 1 for controlling the workbench 1. A limit slide rail 3 is installed on the top of the workbench 1, and a slider 4 is slidably mounted on the top of the limit slide rail 3. A crossbar 5 is fixedly mounted on the top of the slider 4. The length direction of the crossbar 5 is the front-to-back direction. There is a gap between the bottom surface of the crossbar 5 and the top surface of the workbench 1. Linear drive motors 6 are symmetrically arranged at the bottom of the crossbar 5. Fixing blocks 7 are fixedly mounted on the drive shafts of the linear drive motors 6. Nozzles 8 are fixedly mounted on the fixing blocks 7. A traveling drag chain is fixedly mounted on the top of the crossbar 5. The traveling drag chain contains wiring harnesses and pipes. A liquid storage tank 9 is installed at the bottom of the workbench 1. The pipes are used to connect the nozzles 8 and the liquid storage tank 9. The wiring harness is used to electrically connect the nozzles 8, the liquid storage tank 9, and the workbench 1. An infrared sensor is installed at the bottom of each nozzle 8. The rangefinder includes a worktable 1 with multiple threaded grooves evenly distributed on its top. Each threaded groove is screwed with a screw 10. The top surface of each screw 10 has a scribed groove. When placing a workpiece on the worktable surface, some screws can be rotated so that their top surfaces are higher than the top surface of the worktable. This is used to elevate thin plates during spraying, making it easier for the infrared rangefinder to read and identify them. The surface of the worktable 1 has grid lines. By aligning the grid lines with the scribed grooves, multiple screws can be quickly rotated to the same height. The top left and right sides of the worktable 1 are equipped with laterally driven telescopic cylinders. A baffle is fixedly installed on the top rod of each telescopic cylinder. The telescopic cylinder is used to move the baffle closer to / away from the center of the worktable 1. The limiting slide rail 3 is a linearly driven pneumatic guide rail. Support rods are provided at the four corners of the top of the worktable 1, and a top plate is fixedly installed on the top of each support rod.

[0022] Specific implementation process: The nozzle is driven by a linear drive motor to slide back and forth on the crossbar. The crossbar can be moved left and right by the slider on the limit rail at the top of the worktable, realizing the initial automated control of the nozzle, a key part of the spraying equipment. By using an infrared rangefinder installed at the bottom of the nozzle, the boundary of the workpiece located at the top of the worktable can be scanned. Because the workpiece has thickness, the distance measured by the infrared rangefinder will decrease sharply when the nozzle passes through and reaches the surface of the workpiece, thus realizing the effect of automatic spraying of workpieces with different boundaries.

[0023] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly.
