Description

Technical Field

[0001] The present application relates to the technical field of gluing equipment, and in particular to a gluing device for automobile roofs. Background Art

[0002] In order to improve the waterproof performance of the car roof, some gaps in the car roof are usually coated with glue. Usually, the gluing work of the car roof is done by workers using a handheld glue gun.

[0003] For example, the utility model patent CN105312188A discloses a glue gun that uses a push rod to squeeze a cartridge filled with liquid glue, causing the glue to be discharged from a nozzle. As the glue flows from the nozzle, a worker moves the glue gun along the gap in the car roof to complete the glue application.

[0004] For the gluing of small parts, it is more convenient to use a handheld glue gun. However, for parts that need to be glued over a large area, such as the car roof, the labor burden of the workers is heavy. In addition, due to the size of the car roof, some parts of the roof are inconvenient for the workers to reach, resulting in low gluing efficiency. Utility Model Content

[0005] In order to improve the efficiency of gluing a car roof, the present application provides a gluing device for a car roof.

[0006] The present application provides a car roof gluing device that adopts the following technical solution:

[0007] A glue coating device for a car roof includes a glue nozzle, a mechanical arm, and a support base. The support base is used to place a workpiece. The mechanical arm is arranged on one side of the support base. The glue nozzle is installed on the mechanical arm. The mechanical arm can drive the glue nozzle to move.

[0008] By adopting this technical solution, the glue nozzle is connected to the pump body, which supplies glue to the nozzle. The PLC program then controls the movement of the robotic arm, which drives the glue nozzle, achieving automatic glue application on the workpiece (car roof). This replaces manual gluing, reduces the workload, and improves gluing efficiency.

[0009] Optionally, the support base includes a placement platform and supporting legs, the placement platform is arranged horizontally, and the supporting legs are arranged below the placement platform to support the placement platform.

[0010] By adopting the above technical solution, a flat placement space is provided for the workpiece via the placement platform, which facilitates the placement of the workpiece.

[0011] Optionally, a limiting block is provided on the placement platform, and after the workpiece is placed on the placement platform, the limiting block can press against the workpiece to limit the workpiece.

[0012] By adopting the above technical solution, the workpiece is positioned and limited by the limit block, thereby improving the stability of the workpiece during the gluing process.

[0013] Optionally, the glue discharge nozzle is slidably connected to the robotic arm.

[0014] By adopting the above technical solution, the movement range of the glue dispensing nozzle can be further expanded by sliding the glue dispensing nozzle, so as to facilitate the glue coating work of different types of automobile roofs.

[0015] Optionally, the glue dispensing nozzle can rotate relative to the robotic arm, and the rotation axis of the glue dispensing nozzle is perpendicular to its own sliding direction.

[0016] By adopting the above technical solution, the glue nozzle is rotatably connected to the robotic arm, and the angle of the glue nozzle can be adjusted. This makes it easier to apply glue to some tricky angles of the car roof and compensates for the range of the glue nozzle angle change controlled by the robotic arm.

[0017] Optionally, a fixed shaft is provided on the robotic arm, and the fixed shaft can slide relative to the robotic arm. A rotating sleeve is provided on the glue discharge nozzle, and the rotating sleeve is rotatably mounted on the fixed shaft.

[0018] By adopting the above technical solution, the sliding and rotation between the glue dispensing nozzle and the robotic arm are achieved through the cooperation between the rotating sleeve and the fixed shaft.

[0019] Optionally, a tightening piece is provided on the fixed shaft, and the tightening piece is made of an elastic material. The tightening piece can be bent to tighten the rotating sleeve.

[0020] By adopting the above technical solution, the rotating sleeve is pressed against the retaining plate to limit the rotation of the rotating sleeve. In actual production, after adjusting the angle of the glue nozzle as needed, the retaining plate can be used to limit the rotating sleeve, thereby improving the stability of the glue nozzle during the glue application process.

[0021] Optionally, a driving member is provided on the fixed shaft, and the driving member is threadedly connected to the fixed shaft. Rotating the driving member can make the driving member move in a direction parallel to the length direction of the fixed shaft. A driving inclined surface is provided on the driving member, and the clamping plate abuts against the driving inclined surface. The movement of the driving member can drive the clamping plate to bend in a direction close to the rotating ring.

[0022] By adopting the above technical solution, the driving member drives the clamping piece to bend, thereby adjusting the position of the clamping piece. At the same time, the self-locking property of the thread is utilized to improve the stability of the clamping piece in limiting the rotating sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses a gluing device for a car roof.

[0029] Reference Figure 1 and Figure 2 A glue coating device for a car roof comprises a support base 1, a robotic arm 2, and a glue nozzle 3. The support base 1 is used to place a workpiece (here, the car roof). The robotic arm 2 is positioned on one side of the support base 1, and the glue nozzle 3 is mounted on the robotic arm 2. The robotic arm 2 (RM65-B) is capable of driving the glue nozzle 3. The glue nozzle 3 is connected to a pump body, which injects liquid glue into the glue nozzle 3 and then discharges it from the glue nozzle 3. The robotic arm 2 is controlled by a PLC program, driving the glue nozzle 3 to automatically move and achieve automatic glue coating, thereby reducing the workload of the operator.

[0030] Reference Figure 1 and Figure 2 The support base 1 includes legs 11 and a placement platform 12. The placement platform 12 is a plate-shaped structure and is arranged horizontally. The legs 11 are vertically welded to the bottom of the placement platform 12 to support the placement platform 12. A plurality of limit blocks 13 are welded above the placement platform 12. After the workpiece is placed on the placement platform 12, the limit blocks 13 can limit the workpiece in place, improving the stability of the workpiece during the glue coating process.

[0031] Reference Figure 1 and Figure 2A mounting bracket 25 is provided below the robotic arm 2, which is fixed to the ground. The base 21 of the robotic arm 2 is fixedly connected to the base 21 by screws to achieve the installation of the robotic arm 2. At the same time, the robotic arm 2 is kept away from the ground to reduce the impact of moisture on the electronic components inside the robotic arm 2.

[0032] Reference Figure 1 and Figure 2 , define the side of the robotic arm 2 away from the mounting frame 25 as the output end 22 of the robotic arm 2, and a mounting plate 23 is provided between the output end 22 and the glue nozzle 3, and the mounting plate 23 is provided perpendicular to the output end 22. The glue nozzle 3 is mounted on the mounting plate 23 and can move in a direction perpendicular to the mounting plate 23. By controlling the movement of the glue nozzle 3, the movement stroke of the glue nozzle 3 driven by the robotic arm 2 can be compensated, thereby further expanding the range of motion of the glue nozzle 3. An electric push rod 24 is provided between the glue nozzle 3 and the mounting plate 23, the housing of the electric push rod 24 is fixedly connected to the mounting plate 23, the push rod of the electric push rod 24 is connected to the glue nozzle 3, and the push rod movement of the electric push rod 24 can drive the glue nozzle 3 to move, thereby driving the movement of the glue nozzle 3.

[0033] Reference Figure 1 and Figure 2 A microwave radar 6 is also provided on the mounting plate 23 for detecting the distance between the workpiece and the output end 22 of the robotic arm. The distance to the workpiece is detected by the microwave radar 6. When the distance between the robotic arm and the workpiece is less than a certain threshold, the controller controls the robotic arm to stop running, thereby effectively avoiding the collision between the robotic arm 2 and the workpiece.

[0034] Reference Figure 1 and Figure 2 A connecting plate 4 is provided between the glue nozzle 3 and the push rod of the electric push rod 24. The connecting plate 4 is fixedly connected to the push rod of the electric push rod 24 by screws. The glue nozzle 3 is rotatably connected to the connecting plate 4 to compensate for the rotation stroke of the glue nozzle 3 driven by the robotic arm 2, thereby further expanding the application range of the glue coating device.

[0035] Reference Figure 2 and Figure 3 A rotating assembly 5 is provided between the connecting plate 4 and the dispensing nozzle 3. The rotating assembly 5 comprises a fixed shaft 51 welded to the connecting plate 4 and a circular rotating sleeve 52 that is sleeved around the fixed shaft 51. The length of the fixed shaft 51 is perpendicular to the direction of movement of the push rod. The dispensing nozzle 3 is fixed to the rotating sleeve 52 to achieve a rotational connection between the dispensing nozzle 3 and the connecting plate 4.

[0036] Reference Figure 2 and Figure 3The rotating assembly 5 also includes a tightening piece 53, which extends from the side of the rotating sleeve 52 away from the connecting plate 4 to the side of the fixed shaft 51 away from the connecting plate 4. One end of the tightening piece 53 is welded to the fixed shaft 51, and the other end extends in a direction away from the connecting plate 4. The tightening piece 53 is made of elastic metal material. The tightening piece 53 is tilted in a direction away from the axis of the fixed shaft 51 so that the tightening piece 53 can press against the inner side wall of the rotating sleeve 52, thereby limiting the rotation of the rotating sleeve 52. After the angle adjustment of the glue nozzle 3 is completed, the tightening piece 53 can press against the rotating sleeve 52, thereby limiting the rotation of the rotating sleeve 52 and improving the stability of the glue nozzle 3 during use.

[0037] Reference Figure 2 and Figure 3 , a plurality of tightening plates 53 can be evenly spaced around the axis of the fixed shaft 51 to improve the stability of the limiting of the rotating sleeve 52. In this embodiment, four are set. The rotating assembly 5 also includes a driving member 54, and the driving member 54 includes a screw portion 541 and a driving portion 542. The screw portion 541 is a cylindrical structure as a whole, and its outer wall is provided with a thread. A thread groove is provided on the fixed shaft 51, and one end of the screw portion 541 is threadedly connected to the thread groove. The driving portion 542 is a cylindrical structure, and one end of it is coaxially welded to the end of the screw portion 541 away from the fixed shaft 51. A driving inclined surface 543 is provided on the driving portion 542, and the driving inclined surface 543 is inclined along its own circumference from the side close to the screw portion 541 to the side away from the screw portion 541 in a direction away from its own axis. The edge line of the side of the clamping piece 53 away from the fixed shaft 51 abuts against the driving inclined surface 543, and the screw part 541 is rotated to drive the driving part 542 close to the fixed shaft 51. Under the action of the driving inclined surface 543, multiple clamping pieces 53 are driven to bend in the direction away from the axis of the fixed shaft 51, so that multiple clamping pieces 53 are synchronously pressed against the rotating sleeve 52, thereby limiting the rotating sleeve 52.

[0038] Reference Figure 2 and Figure 3 In order to improve the stability of the glue nozzle 3 and the connecting plate 4 during rotation, multiple groups of rotating components 5 can be arranged at intervals along the direction of the rotation axis of the glue nozzle 3. In this embodiment, two groups are set, and the two groups of rotating components 5 are respectively arranged on both sides of the connecting plate 4.

[0039] The implementation principle of the gluing device for a car roof in an embodiment of the present application is: a robotic arm 2 replaces the manual gluing of workers, thereby reducing the pulling burden of the workers and improving the gluing efficiency of the car roof.
