Description

Technical Field

[0001] This invention belongs to the field of adhesive coating technology and relates to an adhesive coating mechanism, specifically an adhesive coating device for workpiece intersection lines. Background Technology

[0002] In existing technologies, the application of adhesive for sealing workpieces with complex spatial intersection lines generally relies on manual operation using a handheld glue gun. This manual method has significant drawbacks: First, operators struggle to accurately control the glue gun's movement along the three-dimensional intersection path using visual inspection and touch, easily leading to deviations from design requirements. This results in inconsistent glue line width, discontinuities, localized accumulation, or missed areas, severely impacting the uniformity and reliability of the sealant layer and creating potential quality issues for subsequent product use. Second, the speed and stability of manual operation are greatly affected by the operator's skill level and physical condition, resulting in low overall application efficiency, prolonged production cycles, and limited capacity expansion. Furthermore, consistency between different batches or operators is difficult to guarantee, leading to significant fluctuations in product qualification rates. Third, applying adhesive to complex intersection lines requires high worker skills, necessitating substantial time and cost for training. The high intensity of manual work also easily induces fatigue, further exacerbating quality fluctuations and efficiency losses. More seriously, the cost of rework or scrapping is exorbitant once poor application occurs. Therefore, existing manual glue application methods face severe challenges in terms of glue application quality, production efficiency, cost control, and process stability. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a workpiece intersection line adhesive application device, which can automatically complete the adhesive application operation of the workpiece intersection line, thereby improving the accuracy and consistency of the adhesive application operation.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A workpiece intersection line adhesive application device includes: a base plate, a vertical plate, a first support rod, a first connecting rod assembly, a glue gun, a motor, and a limiting guide mechanism. The vertical plate is vertically connected to one end of the base plate. The first support rod is parallel to the top of the base plate, with one end fixedly connected to the vertical plate and the other end hinged to the parallel first connecting rod assembly. The first connecting rod assembly is vertically sleeved on the glue gun and slidably connected to it. The motor drives the first connecting rod assembly to rotate the glue gun around the motor on a first plane parallel to the base plate. One end of the limiting guide mechanism is fixedly connected to the vertical plate, and the other end is connected to the glue gun to limit and adjust the rotation path of the glue gun, guiding the glue gun to perform an intersection line movement of a preset diameter to apply adhesive to the workpiece on the base plate.

[0006] Furthermore, the first linkage assembly includes: a first rotating rod and a first adjusting rod. One end of the first rotating rod is vertically connected to a rotating shaft, and a rotating hole adapted to the rotating shaft is opened on the first support rod. The rotating shaft passes through the rotating hole and is connected to the motor. One end of the first adjusting rod is connected to the first rotating rod, and the other end is provided with a first sliding hole.

[0007] Furthermore, a first groove is provided on the first rotating rod along the axial direction, and a first bolt is slidably connected in the first groove. The first bolt passes through the first groove and is threadedly connected and fastened to the first adjusting rod.

[0008] Furthermore, the glue gun includes: a dispensing head, a first slide bar, and a second slide bar. The first slide bar is arranged parallel to the vertical plate. The dispensing head is connected to one end of the first slide bar. The other end of the first slide bar passes through the first sliding hole and is slidably connected to the first adjusting rod. One end of the second slide bar is vertically connected to the first slide bar, and the other end is connected to the limiting guide mechanism.

[0009] Furthermore, the second slide rod is connected to the first slide rod via the slider. The second slide rod is fixedly connected to one side of the slider. A third sliding hole is provided on the slider. The first slide rod passes through the third sliding hole and is slidably connected to the slider. It is then locked and fixed by a third bolt on the other side of the slider.

[0010] Furthermore, the limiting and guiding mechanism includes: a second support rod and a second connecting rod assembly. The second support rod is arranged parallel above the base plate. One end of the second support rod is fixedly connected to the vertical plate, and the other end is hinged to the vertically arranged second connecting rod assembly. The second connecting rod assembly is vertically sleeved on the second slide rod and slidably connected to the second slide rod, so that while the glue gun rotates around the motor on the first plane, it must also rotate around the second support rod on the second plane parallel to the vertical plate to form an intersection line movement with a preset diameter.

[0011] Furthermore, the second linkage assembly includes: a second rotating rod and a second adjusting rod. One end of the second rotating rod is perpendicularly hinged to the second support rod and can rotate around the second support rod. One end of the second adjusting rod is connected to the second rotating rod, and the other end is provided with a second sliding hole. The second sliding rod passes through the second sliding hole and is slidably connected to the second adjusting rod.

[0012] Furthermore, a second groove is provided on the second rotating rod along the axial direction, and a second bolt is slidably connected in the second groove. The second bolt passes through the second groove and is threadedly connected and fastened to the second adjusting rod.

[0013] Furthermore, the base plate is provided with a positioning seat, and the positioning seat has a positioning groove corresponding to the workpiece, and the workpiece is placed in the positioning groove for positioning and fixing.

[0014] The beneficial effects of this invention are as follows: The workpiece intersection line gluing device provided in this application, through an innovative dual-plane linkage design, uses a motor-driven first linkage assembly to rotate the glue gun on a first plane parallel to the base plate, while a limiting and guiding mechanism constrains the glue gun to rotate synchronously on a second plane parallel to the vertical plate. The two work together to force the glue gun to accurately form an intersection line motion trajectory with a preset diameter, realizing the automation and standardization of the intersection line gluing operation, greatly reducing the difficulty and error risk of manual operation, and significantly improving the accuracy and consistency of the gluing operation. It has a simple structure, high efficiency, is easy to implement, and has low cost. The first and second linkage assemblies adopt an adjustment rod structure with a strip groove, which can conveniently adjust the rotation radius of the glue gun on the first and second planes, enabling the gluing operation of intersection lines with various diameters. This breaks through the limitations of the intersection line gluing operation, allowing the device to quickly adapt to the intersection line gluing needs of workpieces of different specifications, and has high flexibility.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the present invention provides a workpiece intersection line gluing device, including: a base plate 1, a vertical plate 2, a first support rod 3, a first connecting rod assembly 4, a glue gun 5, a motor 6, and a limiting guide mechanism 7. The base plate 1 is provided with a positioning seat 9, and the positioning seat 9 is provided with a positioning groove corresponding to the workpiece 8. The workpiece 8 is adapted to be placed in the positioning groove for positioning and fixing, so as to ensure that the workpiece 8 will not move during the gluing operation.

[0021] The first support rod 3 and the first connecting rod assembly 4 are both arranged parallel above the base plate 1. The vertical plate 2 is vertically connected to one end of the base plate 1, and the glue gun 5 is arranged parallel inside the vertical plate 2. One end of the first support rod 3 is fixedly connected to the vertical plate 2, and the other end of the first support rod 3 is hinged to the parallel first connecting rod assembly 4. The first connecting rod assembly 4 is vertically sleeved on the glue gun 5 and slidably connected to the glue gun 5. The motor 6 drives the first connecting rod assembly 4 to drive the first connecting rod assembly 4 to rotate the glue gun 5 around the motor 6 on a first plane parallel to the base plate 1. One end of the limiting and guiding mechanism 7 is fixedly connected to the vertical plate 2, and the other end is connected to the glue gun 5 to limit and adjust the rotation path of the glue gun 5, guiding the glue gun 5 to perform an intersecting line movement of a preset diameter to apply glue to the workpiece 8 on the base plate 1.

[0022] Specifically, such as Figure 2 As shown, the first linkage assembly 4 includes: a first rotating rod 41 and a first adjusting rod 42. One end of the first rotating rod 41 is vertically connected to a rotating shaft 43. A rotating hole 31 adapted to the rotating shaft 43 is provided on the first support rod 3. The rotating shaft 43 passes through the rotating hole 31 and is connected to the motor 6. The motor 6 drives the rotating shaft 43 to rotate within the rotating hole 31, thereby causing the first rotating rod 41 to rotate around the motor 6 on a first plane. One end of the first adjusting rod 42 is connected to the first rotating rod 41, and the other end of the first adjusting rod 42 is provided with a first sliding hole 44. The first adjusting rod 42 is vertically sleeved on the glue gun 5 through the first sliding hole 44. A first groove 45 is provided on the first rotating rod 41 along the axial direction. A first bolt 46 is slidably connected in the first groove 45. The first bolt 46 passes through the first groove 45 and is threadedly connected and fastened to the first adjusting rod 42. The rotation radius of the glue gun 5 around the motor 6 can be adjusted by sliding the first bolt 46 in the first groove 45. The glue gun 5 can be locked and fixed by tightening the first bolt 46, thereby realizing the preset adjustment of the diameter of the glue gun 5 moving in the intersecting line.

[0023] like Figure 3 As shown, the glue gun 5 includes: a dispensing head 51, a first slide rod 52, and a second slide rod 53. The first slide rod 52 is arranged parallel to the vertical plate 2. The dispensing head 51 is connected to one end of the first slide rod 52. The other end of the first slide rod 52 passes through the first sliding hole 44 and is slidably connected to the first adjusting rod 42, maintaining the vertical freedom of movement of the glue gun 5. One end of the second slide rod 53 is vertically connected to the first slide rod 52, and the other end is connected to the limiting guide mechanism 7, thereby limiting and guiding the vertical movement path of the glue gun 5 through the limiting guide mechanism 7. The second slide rod 53 is connected to the first slide rod 52 through a slider 54. The second slide rod 53 is fixedly connected to one side of the slider 54. The slider 54 has a third sliding hole 55. The first slide rod 52 passes through the third sliding hole 55 and is slidably connected to the slider 54, and is locked and fixed by a third bolt 56 on the other side of the slider 54, thereby realizing the adjustment of the height of the glue gun 5 during glue application.

[0024] like Figure 4 As shown, the limiting guide mechanism 7 includes: a second support rod 71 and a second connecting rod assembly 72. The second support rod 71 is arranged parallel above the base plate 1. One end of the second support rod 71 is fixedly connected to the vertical plate 2, and the other end is hinged to the vertically arranged second connecting rod assembly 72. The second connecting rod assembly 72 is vertically sleeved on the second slide rod 53 and slidably connected to the second slide rod 53, so that while the glue gun 5 rotates around the motor 6 on the first plane, it must also rotate around the second support rod 71 on the second plane parallel to the vertical plate 2 to form an intersection line movement with a preset diameter.

[0025] The second linkage assembly 72 includes a second rotating rod 73 and a second adjusting rod 74. One end of the second rotating rod 73 is vertically hinged to the second support rod 71, allowing the second rotating rod 73 to rotate around the second support rod 71. One end of the second adjusting rod 74 is connected to the second rotating rod 73, and the other end of the second adjusting rod 74 has a second sliding hole 75. The second sliding rod 53 passes through the second sliding hole 75 and is slidably connected to the second adjusting rod 74, so that the limiting guide mechanism 7 does not interfere with the horizontal freedom of movement of the glue gun 5. A second strip groove 76 is provided axially on the second rotating rod 73. A second bolt 77 is slidably connected in the second strip groove 76. The second bolt 77 passes through the second strip groove 76 and is connected and fastened to the second adjusting rod 74. By sliding the second bolt 77 in the second strip groove 76, the rotation radius of the glue gun 5 on the second plane can be set to be consistent with the rotation radius on the first plane. By tightening the second bolt 77, it is locked and fixed, thereby realizing the preset adjustment of the diameter of the glue gun 5's intersecting line movement.

[0026] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
