Description

Technical Field

[0001] The present application relates to the field of an automatic glue coating gun nozzle device for automobile door frame sealing, and in particular to a special-shaped gun nozzle for coating glue on automobile front door hinges. Background Art

[0002] With the continuous development of automated production technology in the automotive industry, in order to reduce labor intensity, improve work efficiency, and ensure quality and consistency, the automotive gluing production line has been transformed from manual operation to robotic automatic operation. During the application of door opening robot gluing, due to the interference of sheet metal between the car body door and the hinge, the rubber strip from the door hinge cannot be glued through the existing gun nozzle, which cannot meet the requirements of the robot door opening gluing operation. How to make the robot gun nozzle penetrate into the door hinge for gluing operation, and meet the requirements of gluing four doors of various models, and adapt to new models by changing the structural dimensions. The four-door nozzle of the special-shaped glue gun is becoming more and more widely used.

[0003] At present, the glue gun spraying used in the door frame sealant production lines of most automobile factories cannot meet the requirements of the robot door hinge glue application technology. The typical problems are:

[0004] 1. Currently, the door frame sealant production line in automobile factories uses manual glue spraying. The glue application method is to manually open the door and position the glue. The structure and shape of the manual spray gun nozzle cannot penetrate into the door hinge gap to apply glue when the door is closed.

[0005] 2. Very few car factories use robots to apply glue to door frames. However, the structure and shape of robots do not allow robots to penetrate deep into the gaps between door hinges to apply glue.

[0006] 3. The closed-door gluing operation adopted by robots in very few automobile factories has a brittle nozzle structure that is prone to breakage and lacks structural ductility.

[0007] There is no good solution to the technical problems existing in the above-mentioned process of sealing and gluing automobile door frames, so there is an urgent need to find an effective solution to solve the above-mentioned problems. Utility Model Content

[0008] In order to solve the above problems, the present application provides a special-shaped gun nozzle for gluing automobile front door hinges.

[0009] The special-shaped nozzle for gluing automobile front door hinges provided in this application adopts the following technical solution:

[0010] A special-shaped gun nozzle for gluing automobile front door hinges, comprising

[0011] A mounting base is provided, wherein a glue inlet is provided at the center of the mounting base and is communicated with the glue outlet of the glue gun of the robot arm. Mounting holes are provided on both sides of the glue inlet of the mounting base and are fixedly connected to the glue gun of the robot arm. The mounting base is fixed to the glue outlet of the glue gun of the robot arm by screws through the mounting holes.

[0012] A glue supply reinforcement tube, the glue supply reinforcement tube being perpendicular to the surface of the mounting base and fixedly connected to the glue inlet;

[0013] A glue supply hose, one end of which is inserted into the glue supply reinforcement pipe and fixedly connected to the glue supply reinforcement pipe. The diameter of the glue supply hose is smaller than the door hinge gap.

[0014] By adopting the above technical solution, the mounting base is mounted on the glue gun of the robot arm, and the diameter of the glue supply hose is smaller than the door hinge gap, so the glue supply hose can be inserted from the door hinge gap, which is convenient for mounting the base on the glue gun of the robot arm. The diameter of the glue supply hose is smaller than the door hinge gap, so the glue supply hose can be inserted from the door hinge gap, which is convenient for gluing the inside of the sheet metal gap of the car's front door hinge. The glue in the glue gun of the robot arm passes through the glue inlet of the mounting base and the glue supply reinforcement tube into the glue supply hose, and gluing is performed at the glue supply hose port. The glue in the glue gun of the robot arm passes through the glue inlet of the mounting base and the glue supply reinforcement tube into the glue supply hose, and gluing is performed at the glue supply hose port.

[0015] Preferably, a sealing ring is provided when the mounting base is mounted on the glue gun outlet, and the mounting base is fixed on the glue gun outlet by bolts.

[0016] By adopting the above technical solution, the mounting base is connected to the glue gun through bolts, and the glue outlet and the mounting base are sealed by setting a sealing ring. The mounting base can be connected to the glue outlet of the glue gun without a gap, and glue leakage will not occur.

[0017] Preferably, the diameter of the rubber supply hose can be set to 2-3 mm.

[0018] By adopting the above technical solution, the gap between the front door and the fender of the vehicle body is generally 4mm, and the diameter of the supply hose is set to 2-3mm, which makes it easier for the discharge hose to penetrate into the gap.

[0019] Preferably, the rubber supply hose is made of high-hardness metal.

[0020] By adopting the above technical solution, the rubber supply hose will penetrate into the gap of the door hinge to carry out the gluing operation. During the operation, the door is in the open state. The door will be closed due to external force or other circumstances. At this time, it is easy to generate a large clamping force on the rubber supply hose. The rubber supply hose is made of high-hardness metal to avoid the possibility of the rubber supply hose being broken due to collision when the door is closed, and to avoid the rubber material spraying on the sheet metal body and causing pollution to the body due to the breakage of the rubber supply hose.

[0021] Preferably, the glue outlet of the glue supply hose is deburred during processing, and the glue outlet is polished smooth.

[0022] By adopting the above technical solution, the burrs at the glue outlet are removed and the processing is smooth, so that the glue can be squeezed out smoothly from the glue outlet during glue discharge, thereby improving the stability during glue discharge.

[0023] Preferably, one end of the glue outlet of the glue supply hose is configured to be hook-shaped.

[0024] By adopting the above technical solution, after the glue outlet of the glue supply hose is inserted into the gap of the car door hinge, the glue outlet can be controlled to move left and right and forward and backward by rotating the glue supply hose to meet the glue outlet position, which is convenient for adjusting the glue outlet. By adjusting the distance and spraying speed, the same glue outlet can meet the shapes of glue strips of different widths and thicknesses.

[0025] Preferably, the thickness of the glue supply reinforcement tube can be set to 0.8-1.5 mm, and the length of the end of the glue supply reinforcement tube connected to the glue inlet can be set to 120-150 mm.

[0026] By adopting the above technical solution, since the overall nozzle is longer, by thickening the glue supply reinforcement tube, thickening the wall of the glue supply reinforcement tube, and lengthening the length of the glue supply reinforcement tube as much as possible, the stability of the overall gun nozzle can be met, thereby enhancing the glue discharge stability.

[0027] Preferably, it also includes a glue outlet pipe, which is arranged on one side of the glue supply pipe outlet and perpendicular to the axis of the glue supply pipe outlet. One end of the glue outlet pipe is connected to the glue outlet pipe, and a sealing cover is provided at the glue supply pipe outlet.

[0028] By adopting the above technical solution, the rubber supply hose outlet is blocked with a sealing cap, preventing the rubber from flowing out through the rubber supply hose outlet. At the same time, the rubber is allowed to flow out through the rubber outlet pipe. Since the rubber outlet pipe is perpendicular to the axis of the rubber supply hose outlet, the direction of the rubber outlet is perpendicular to the original direction, which can meet the requirements of rubber spraying for various vehicle models. In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The mounting base is installed on the glue gun of the robot arm. The diameter of the glue supply hose is smaller than the door hinge gap. The glue supply hose can be inserted from the door hinge gap to facilitate gluing operations inside the sheet metal gap of the front door hinge of the car. The glue in the glue gun of the robot arm passes through the glue inlet of the mounting base and the glue supply reinforcement tube into the glue supply hose, and gluing operations are performed at the glue supply hose port. The glue in the glue gun of the robot arm passes through the glue inlet of the mounting base and the glue supply reinforcement tube into the glue supply hose, and gluing operations are performed at the glue supply hose port.

[0030] 2. The supply hose will penetrate into the gap of the door hinge to apply glue. During this operation, the door is open. The door may close due to external force or other circumstances. At this time, it is easy to generate a large clamping force on the supply hose. The supply hose should be made of high-hardness metal to avoid the possibility of the supply hose being hit and broken when the door is closed. It also prevents the rubber material from spraying onto the sheet metal body and causing contamination of the body due to the breakage of the supply hose.

[0031] 3. Use the sealing cap to block the glue outlet of the supply hose to prohibit the glue material from flowing out through the glue outlet of the supply hose. At the same time, the glue material flows out through the discharge hose. Because the discharge hose and the axis of the glue outlet of the supply hose are perpendicular to each other, the glue discharge direction is perpendicular to the original direction, which can meet the needs of glue spraying for various models.

[0036] The embodiment of the present application discloses a special-shaped gun nozzle for gluing the front door hinge of an automobile. Figure 1 The special-shaped gun nozzle for gluing the front door hinge of the car includes a mounting base 1, a glue supply reinforcement tube 2, a glue supply tube 3 and a glue outlet tube 4.

[0037] Reference Figure 1 The mounting base 1 is a long metal rectangular plate with a glue inlet 11 at the center and mounting holes 12 on both sides of the glue inlet 11. The mounting base 1 is installed on the robot arm glue gun by screws passing through the mounting holes 12. The glue inlet 11 is connected to the glue outlet of the glue gun. In order to ensure that the mounting base 1 and the glue gun do not leak glue after installation, a sealing ring 13 is provided at the glue inlet 11 of the mounting base 1 and the glue outlet of the glue gun. The sealing ring 13 can be set as an O-type rubber ring.

The main body length can be set to 120-150mm. By thickening the glue supply reinforcement tube 2, thickening the tube wall of the glue supply reinforcement tube 2, and lengthening the length of the glue supply reinforcement tube 2 as much as possible, the stability of the overall gun nozzle can be met, thereby enhancing the glue discharge stability.

[0039] One end of the glue supply hose 3 is connected to the glue supply reinforcement tube 2. Specifically, the glue supply hose 3 is inserted into the glue supply reinforcement tube 2, and the end of the glue supply hose 3 connected to the glue supply reinforcement tube 2 is bent, and the bending angle is 135°. After being connected to the glue supply reinforcement tube 2, the main body of the glue supply hose 3 is vertical to the main body of the glue supply reinforcement tube 2.

[0040] The diameter of the supply hose 3 can be set to 2-3mm. The gap between the front door and the fender of the vehicle body is generally 4mm. Setting the diameter of the supply hose 3 to 2-3mm makes it easier for the discharge hose 4 to penetrate into the gap.

[0041] The rubber supply hose 3 is made of high-hardness metal, and the burrs on the rubber outlet of the rubber supply hose 3 are removed during processing, and the rubber outlet is polished smooth to avoid the possibility of the rubber supply hose 3 being broken by collision when the car door is closed, and to avoid the rubber spraying on the sheet metal body due to the breakage of the rubber outlet hose 4, causing pollution to the car body.

[0042] Reference Figure 1 、 Figure 2 The glue outlet pipe 4 is arranged at one end of the glue outlet of the glue supply pipe 3. Specifically, the side surface of the last section of the hook of the glue supply pipe 3 is perpendicular to the axis of the glue outlet of the glue supply pipe 3 and faces the main body of the glue supply pipe 3, which meets the requirements of glue spraying for various models.

[0043] Reference Figure 2 In order to ensure that the rubber material can flow out from the rubber outlet pipe 4, a sealing cover 31 is provided at the rubber outlet of the rubber supply pipe 3, and the sealing cover 31 can seal the rubber outlet of the rubber supply pipe 3.

[0044] The implementation principle of the special-shaped gun nozzle for gluing the front door hinge of an automobile in an embodiment of the present application is as follows: the mounting base 1 is mounted on the glue gun of the robot arm, and the diameter of the glue supply hose 3 is smaller than the gap of the door hinge. The glue supply hose 3 can be inserted from the gap of the door hinge, which is convenient for gluing the inside of the sheet metal gap of the front door hinge of the automobile. The glue in the glue gun of the robot arm passes through the glue inlet 11 of the mounting base 1 and the glue supply port 12. The strengthening tube 2 is connected to the glue supply tube 3, and the glue coating operation is carried out at the end of the glue supply tube 3. The glue in the glue gun of the robotic arm is connected to the glue supply tube 3 through the glue inlet 11 of the mounting base 1 and the glue supply strengthening tube 2, and the glue coating operation is carried out at the end of the glue supply tube 3. The glue supply tube 3 is set, and the glue outlet of the glue supply tube 3 is blocked with a sealing cover 31 to prohibit the glue from flowing out through the glue outlet of the glue supply tube 3. At the same time, the glue is made to flow out through the glue outlet tube 4. Since the glue outlet tube 4 is perpendicular to the axis of the glue outlet of the glue supply tube 3, the glue discharge direction is perpendicular to the original direction, which can meet the requirements of glue spraying for various models.
