Description

Technical Field

[0001] The utility model relates to a monitoring mechanism for gluing automobile windshields, and is applicable to the technical field of automobile assembly equipment. Background Art

[0002] Before installing the car windshield, glue needs to be applied to achieve good adhesion between the glass and the car body, and provide reliable sealing and water leakage prevention. The existing automobile gluing technology uses a mechanical arm to apply glue. When the mechanical arm is applying glue, the joint at the end of the mechanical arm needs to rotate 360 ​​degrees around the glass to complete the gluing of the entire glass.

[0003] The gluing process of the robot arm has problems of glue breakage and glue collapse, which has caused problems with the stability of the installation quality of the front and rear windshields. The gluing quality of the robot arm needs to be tested. During the gluing quality test, personnel need to check the gluing status of the robot arm in real time, which can easily cause fatigue; at the same time, the accuracy of personnel detection is poor, and it is impossible to detect the small collapse problem that occurs during the gluing process of the robot arm, which can easily affect the subsequent production process and have a great impact on the yield rate of vehicle production. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the above technical problem, the utility model provides a monitoring mechanism for the glue application of automobile windshield.

[0005] The technical solution adopted by the utility model is: a monitoring mechanism for glue application on automobile windshields, a glue supply pump is installed at the end of the mechanical arm, and a glue coating head is installed at the output end of the glue supply pump, which is characterized by:

[0006] The glue shape detection sensor is mounted on the glue coating head through the mounting structure. The glue shape detection sensor is used to detect the glue quality during the glue coating process.

[0007] The controller is connected to the glue shape detection sensor through a cable circuit. The controller is used to control the start and stop of the glue shape detection sensor and receive information obtained by the glue shape detection sensor. The controller is fixedly mounted on the robotic arm through a mounting bracket. In this way, when the robotic arm drives the glue supply pump and the glue coating head to rotate, the glue shape detection sensor mounted on the glue coating head can rotate synchronously with the glue coating head, and the glue coating direction on the automobile windshield can be kept constant in the image obtained by the glue shape detection sensor, so that the glue shape detection sensor can detect the glue coating quality more accurately.

[0008] A reel is fixedly mounted on the mounting structure, and the cable connecting the glue shape detection sensor and the controller is reeled on the reel. In this way, when the joint at the end of the mechanical arm rotates and drives the glue coating head to rotate, a relative displacement occurs between the interface connecting the cable on the glue shape detection sensor and the interface connecting the cable on the controller. In order to prevent the cable from falling off from the glue shape detection sensor or the controller during the rotation of the joint at the end of the mechanical arm due to its short length, the length of the cable must have a certain redundancy. However, during the rotation of the joint at the end of the mechanical arm, the redundant cable is easily entangled on the glue coating head, which affects the glue application of the glue coating head. The reel arranged on the glue coating head plays a role in winding the cable. When the glue coating head is applying glue, it rotates 360° to apply the glass glue to the glass. When the glue coating head rotates clockwise, the cable is wound on the reel. When the glue coating head rotates counterclockwise, the cable extends from the reel. By reeling in and out the wire, the winding function of the winder is realized, so that the detector rotates 360° and the cable is not knotted or bent.

[0009] A plurality of limit piles are evenly arranged on the outer side of the reel along the circumference of the reel, so that when the reel reels in and releases the cable, the limit piles can prevent the cable wound on the reel from falling off the reel and causing the cable to wrap around the glue coating head.

[0010] The mounting structure comprises a mounting frame and a mounting clamp, wherein the mounting frame is fixedly mounted on the glue shape detection sensor, and the mounting clamp is fixedly mounted on the mounting frame, and the mounting frame is clamped on the glue coating head by the mounting clamp. Thus, by means of the mounting clamp, it is convenient to clamp the mounting frame, i.e., the glue shape detection sensor, on the glue coating head; at the same time, it is also convenient to remove the glue shape detection sensor from the glue coating head by removing the clamp from the glue coating head, thereby realizing the disassembly and assembly of the glue shape detection sensor on the glue coating head.

[0011] The reel is sleeved on the gluing head, so that the cable can be more effectively reeled on the reel during the rotation of the gluing head.

[0012] The beneficial effects of the utility model are as follows: the utility model installs a clamp to set the glue shape detection sensor on the glue coating head, so that when the mechanical arm drives the glue supply pump and the glue coating head to rotate, the glue shape detection sensor and the glue coating head rotate synchronously, thereby improving the detection accuracy of the glue shape detection sensor; in the utility model, the glue shape detection sensor is set on the glue coating head by the clamp, thereby realizing the disassembly and assembly of the glue shape detection sensor on the glue coating head; the utility model arranges a winding disk outside the glue coating head, which is used for the cable connecting the glue shape detection sensor and the controller when the winding mechanical arm drives the glue coating head to rotate, thereby avoiding the cable being wound around the glue shape detection sensor during the rotation of the glue shape detection sensor.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0017] The present embodiment is a monitoring mechanism for gluing automobile windshields, which is used to monitor the gluing quality during the gluing process on the edge of the automobile windshield when the glue supply pump 1 and the gluing head 2 are driven by a mechanical arm to move along the edge of the automobile windshield.

[0018] In this embodiment, a glue pump 1 is fixedly installed at the joint position of the end of the mechanical arm, and a glue coating head 2 is connected to the output end of the glue pump 1, and the glue coating head 2 can rotate along the axis of the glue coating head 2. In this way, the mechanical arm drives the glue pump 1 and the glue coating head 2 to move along the edge of the automobile windshield, and the glue in the glue pump 1 is evenly coated on the edge of the automobile windshield through the glue coating head 2.

[0019] In this embodiment, a glue shape detection sensor 3 is mounted on the outer surface of the glue coating head 2, and the glue shape detection sensor 3 rotates with the glue coating head 2. A mounting frame 9 is fixedly mounted on the glue shape detection sensor 3, and a mounting clamp 10 is fixedly mounted on the mounting frame 9. By tightening the mounting clamp 10 on the glue coating head 2, the mounting frame 9 and the glue shape detection sensor 3 are fixedly mounted on the glue coating head 2, and it is also convenient to remove and replace the glue shape detection sensor 3 from the glue coating head 2.

[0020] In this embodiment, a mounting bracket 4 is fixedly mounted on the robot arm, and a controller 5 is fixedly mounted on the mounting bracket 4. The controller 5 is connected to the glue shape detection sensor 3 via a cable 11. The controller 5 can control the start and stop of the glue shape detection sensor 3. The information obtained by the glue shape detection sensor 3 will also be sent to the controller 5 for subsequent sending to other devices.

[0021] In this embodiment, since the glue shape detection sensor 3 is installed on the glue coating head 2, the glue shape detection sensor 3 will rotate with the glue coating head 2, while the controller 5 is installed on the mechanical arm, and the controller 5 will not rotate with the glue coating head 2. In this way, during the rotation of the glue coating head 2, the interface of the glue shape detection sensor 3 connected to the cable 11 and the interface of the controller 5 connected to the cable 11 are relatively displaced. In order to prevent the cable 11 from falling off from the glue shape detection sensor 3 or the controller 5 during the rotation of the joint at the end of the mechanical arm due to its short length, the length of the cable 11 needs to have a certain redundancy. However, during the rotation of the joint at the end of the mechanical arm, the redundant cable 11 is easy to be entangled on the glue coating head 2, affecting the glue application of the glue coating head 2, and a reel 7 is fixedly installed on the mounting bracket 4. The winding reel 7 arranged on the glue coating head 2 has a winding function for the cable 11. When the glue coating head 2 is coating glue, the glue coating head 2 will also rotate 360° along the axis of the glue coating head 2 to apply the glass glue to the glass while moving with the robotic arm. When the glue coating head 2 rotates clockwise, the winding reel will automatically reel in the wire. When the glue coating head 2 rotates counterclockwise, the glue coating head 2 will automatically release the wire. The cable 11 is automatically reeled in and placed on the winding reel 7, thereby realizing the winding function of the winder, so that the cable 11 between the glue shape detection sensor 3 and the controller 5 is not knotted or bent during the rotation of the glue shape detection sensor 3 with the glue coating head 2.

[0022] In this embodiment, the reel 7 is mounted on the mounting bracket 4 via the connecting plate 6, and the reel 7 is sleeved on the glue coating head 2. In this way, the cable 11 can be more effectively reeled on the reel 7 during the rotation of the glue coating head 2.

[0023] Furthermore, in order to prevent the cable 11 from falling off the winding drum 7 during the winding process on the winding drum 7 , a plurality of limit piles 8 are evenly arranged on the outer side of the winding drum 7 along the circumference direction of the winding drum 7 .

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
