Description

Technical Field

[0001] The invention discloses an automatic gluing device for a vehicle body roof window frame, which is used for automatic gluing of a sunroof window frame at a sunroof assembly station on an automobile production line and relates to the technical field of design and manufacturing of automatic gluing equipment for vehicle body roof window frames. Background Art

[0002] Cars are now widely used in people's lives. With the improvement of living standards, people have higher demands on the configuration of cars. Among them, the car sunroof is a configuration product among many parts of the car. The car sunroof is assembled from multiple parts. In the sunroof assembly operation of the car production line, it is necessary to apply glue to the sunroof frame, and then assemble glass and other components. In the implementation of the gluing operation, the current modern assembly lines use robots, and the older production lines also use manual gluing operations. Since the surface of the car sunroof that needs to be glued is not a completely straight line, but also has a certain curved surface, and the glue applied also requires the application of two kinds of matching glue; when manual gluing is used, due to manual labor, It is a hand-held glue gun. If it is slightly unstable, the glue will be applied in a crooked manner, which greatly affects the bonding effect. In serious cases, rework is required, resulting in a waste of time, materials and labor. The use of robotic gluing requires adding corresponding equipment to the production line that originally did not have such equipment. It requires program design and adjustment of workstations, which will also bring considerable expenses and cause an increase in automobile production costs. Moreover, the glass sunroof frame needs to be stabilized and fixed in position when gluing. The existing automated program using robotic gluing can only be suitable for the positioning of one model of sunroof frame. After replacing the product, the positioning accuracy will be poor, which will lead to gluing deviation, so all tooling and programs need to be replaced.

[0003] A technology with patent number CN202322645502.7 discloses a skylight gluing pipeline structure, including a glue barrel, a glue filling pipe is installed on the top of one side of the glue barrel, a plug is installed on the glue filling pipe, a glue coating assembly is installed on the bottom of the other side of the glue barrel, a driving assembly is installed on the other side of the glue barrel, a glue extrusion assembly is installed inside the glue barrel, and the glue coating assembly includes a fixed pipe installed at the bottom end of the glue barrel away from the glue filling pipe, a movable pipe is movably installed inside the fixed pipe, and one end of the movable pipe extends to the outside of the end of the fixed pipe away from the glue barrel; the purpose of this technology is to solve the current problem of hose twisting during the movement of the nozzle, which then causes glue discharge blockage. It is not a complete gluing equipment.

[0004] Another technology with patent number CN202211231616.4 discloses a car sunroof glass gluing robot, including a liftable work platform, an air cushion support work platform provided on the liftable work platform, an annular movable work slide surrounding the liftable work platform is laid around the liftable work platform, and a gluing working robot is provided on the annular movable work slide. The car sunroof glass gluing robot of the present invention adopts a glass fixed glue gun movement mode to avoid direct glass gluing, which may cause damage to the glass. Through the intelligent dot matrix air cushion multi-angle support, the lower surface of the glass is uniformly stressed during gluing, avoiding scratches or cracks on the lower surface of the glass. Through laser / infrared uniform thickness measurement, the gluing and thickness measurement processes are carried out simultaneously, which greatly saves the process operation time. This technology has many equipment components and requires a larger installation site. It is suitable for newly planned production lines or comprehensive design and transformation when renovating old production lines. Moreover, this technology is specifically used for gluing sunroof glass.

[0005] This application is aimed at gluing the window frame of the roof skylight, so the above technology is not suitable for the technical problem to be solved by this application;

[0006] The technical difficulty that the present application needs to solve is to solve the problem of non-standard manual gluing of the body roof sunroof window frame, which causes rework and waste. For example, the gluing of the body roof sunroof window frame of the FAW Toyota AVALON model requires gluing of 1241 glue and 320T glue on the window frame parts. The existing production technology uses a glue pump to apply pneumatic pressure to pour the glue in the glue barrel into the glue hose, and then the operator takes the glue gun to manually apply the glue to the window frame parts. Since the amount of glue applied manually is difficult to accurately control, it causes uneven application, excessive position error, and adverse effects on product performance.

[0045] The mobile glue coating mechanism includes a linear screw module 3, a slider 3A, a glue feeding hose elevator 8, a 1241 hose suspension balancer 9, a 1241 hose balancer pulley 10, a 1241 hose balancer traction rope 11, a 320T hose balancer pulley 12, a 320T hose suspension balancer 13, a 320T hose balancer traction rope 14, a tension spring 19, a bearing 20, a 320T glue nozzle 21, and a 1241 glue nozzle 24; a glue feeding hose elevator 8 is provided at a position near the upper ends of the 1241 glue nozzle 24 and the 320T glue nozzle 21 of the 1241 glue feeding hose 1 and the 320T glue nozzle 21, and the other ends of the 1241 hose balancer traction rope 11 and the 320T hose balancer traction rope 14 are connected to the glue feeding hose elevator 8; a slider There are two 3A sliders, and a 1241 glue universal joint 6 and a 320T glue universal joint 7 are fixed on the two sliders 3A by screws respectively; the inner holes of the two sliders 3A are threaded, and after the thread is mounted on the linear screw module 3, as the stepper motor 18 rotates the linear screw module 3, the two sliders 3A move left and right on the thread of the linear screw module 3; in order to realize the whole process of automatic gluing, including starting and stopping gluing, glue discharge sensors are arranged on the two vertical box back plates 34 arranged behind the linear screw module 3, and the glue discharge sensors include the 320T glue discharge sensor 16 and the 1241 glue discharge sensor 17 arranged on the right, and the 320T glue discharge sensor and the 1241 glue discharge sensor arranged on the left.

The structure is sleeved and fixed on the front end of the 320T glue nozzle 21, and a bearing mounting shaft is installed on each of the two strokes of the herringbone shape, and a bearing is installed on each mounting shaft, and the installation direction of the bearing is horizontal movement; the support frame arranged at the glue outlet of the 1241 glue nozzle 24 is an upper and lower end structure, and the upper end is fixedly sleeved on the glue outlet of the 1241 glue nozzle 24, and a bearing mounting shaft is set at the lower end of the support frame in the same direction as the glue outlet, and a bearing that moves horizontally is installed on the mounting shaft, and the direction of the bearing after installation is horizontal movement.

[0047] In order to achieve a fixing effect and be able to withstand long-term movement, the support frame mounted on the front end of the 1241 glue nozzle 24 and the 320T glue nozzle 21 is preferably fixed to the front end of the 1241 glue nozzle 24 and the 320T glue nozzle 21 by welding.

[0048] The aforementioned mobile gluing mechanism uses a linear screw as a transmission mechanism to drive the gluing nozzle to move stably along a preset path. The bearing support clamp, bearing and tension spring can automatically adjust the distance, angle and position between the gluing nozzle and the gluing surface of the part as the curved surface shape of the gluing nozzle and the skylight frame changes. The stepper motor and the glue valve switch control the running speed and direction of the glue nozzle according to the PLC program instructions, and control the opening and closing of the glue valve switch to ensure that the glue nozzle can accurately reach the specified position for gluing and the on and off of gluing.

[0049] The control mechanism includes an operation indicator light 15, a stepper motor 18, a workpiece in place indicator light 4, a power box 22, a drive control box 23, an electric sensor 25, a start button 26, a solenoid valve 27, an emergency stop button 28, and an air pressure regulating switch 29; the operation indicator light 15 is installed in the upper right corner of the rear end facade box of the component placement table 31 for easy observation by personnel, the upper ends of the six electric sensors 25 arranged on the component placement table 31 protrude above the surface of the component placement table 31, and the lower ends of the six electric sensors 25 are fixed by bolts; the lower ends of the six electric sensors 25 have wires connected in series and connected to the control circuit in the drive control box 23 to determine whether the skylight window frame 30 to be glued is in place. If the skylight window frame 30 is placed correctly, the set workpiece in place indicator light 4 will light up, and then the operator can press the set start button 26 to start the gluing work.

[0050] In order to enable the equipment to operate, a power box 22, a drive control box 23 and a circuit breaker are set under the component placement table 31. The power box provides 24V power. The drive control box 23 is equipped with a PLC controller, an electric drive controller and a motor controller. The functions of the PLC controller, the electric drive controller and the motor controller are to execute process control, drive the glue feeding operation of the glue coating mechanism, and control the stepping motor to drive the operation of the linear screw module 3;

[0051] There are two groups of solenoid valves 27, which respectively control the operation of two glue liquid feeding pumps. The rear ends of the two groups of solenoid valves 27 are connected to the control box through wires, and the front ends are connected to the air pressure regulating switch 29 through air pipes. The gas pressure of the glue feeding is controlled by the PLC program in the control box to realize the working process of controlling the glue feeding and stopping of the glue feeding to the 1241 glue feeding pipe 1 and the 320T glue feeding pipe 2; when the glue is applied, the fixed connection between the bearing and the front end of the glue nozzle allows the glue nozzle to automatically adjust the angle and position according to the changes in the window frame curve during the gluing process, and the tension spring plays the role of pulling the glue nozzle to ensure that the glue nozzle can remain stable and tightly fit the surface of the window frame during gluing. Such a setting can ensure that at any time, or when the glue is applied on an object with a curved surface, the distance between the glue nozzle and the curved workpiece can be guaranteed from beginning to end.

[0052] The workbench mechanism includes a balancer slide 5 and a component placement platform 31 . The balancer slide 5 is a door-shaped structure and is installed above the component placement platform 31 in a spanning manner.

[0053] A box-type facade box is connected to the rear of the component placement platform 31 , and a linear screw module 3 is arranged in the facade box. The arrangement height of the linear screw module 3 is higher than the upper end surface height of the component placement platform 31 .

[0054] A slide groove parallel to the linear screw module 3 is provided on the rear end face of the component placement table 31 below the linear screw module 3, and a transverse sliding block is provided in the slide groove. The length of the transverse sliding block matches the width of the two sliders 3A, and the lower end of the tension spring 19 is hung on the sliding block in the lower end slide groove; the balancer slide 5 is above the linear screw module 3, and a slide is provided on the balancer slide 5. The 1241 hose suspension balancer 9 and the 320T hose suspension balancer 13 are suspended by the 1241 hose balancer pulley 10 and the 320T hose balancer pulley 12 and slide left and right in the slide on the balancer slide 5.

[0055] Example 2: Operation of the present invention

[0056] After the 1241 hose universal joint 6 and the 320T hose universal joint 7 are set on the two sliders 3A, the two universal joints of the 1241 hose universal joint 6 and the 320T hose universal joint 7 are parallel. In order to be able to simultaneously apply the glue liquid to the two types of glue with an intersecting surface, the length of the 1241 glue nozzle 24 is shorter than the length of the 320T glue nozzle 21. After the installation is completed, a staggered structure is formed in which the 320T glue nozzle 21 is in front and the 1241 glue nozzle 24 is in the back.

[0057] Since the sunroof window frame of the vehicle body to which glue is applied is a curved structure, in order to ensure that the distance between the glue nozzle and the object to be glued is at the same distance from beginning to end when applying glue, a support frame for mounting a bearing is respectively provided at the front end of the 1241 glue nozzle 24 and the 320T glue nozzle 21. The support mounted at the front end of the 320T glue nozzle 21 is a herringbone bracket, and the upper part of the herringbone is vertically in a circle shape. The circle shape is sleeved and welded to the front end of the 320T glue nozzle 21, and the two strokes of the herringbone shape are respectively connected to the 320T glue nozzle 21. An axis is installed with the same axial direction, and a bearing is installed on each axis. The bearings are in a horizontal walking state after installation. A vertical support frame is installed at the full end of the 1241 glue nozzle 24. The upper end of the support frame is inserted into and welded to the 1241 glue nozzle 24. An axis with the same axial direction as the 1241 glue nozzle 24 is set at the lower end of the vertical support frame, and a horizontal walking bearing is installed on the axis. During operation, the bearings arranged at the front end of the 320T glue nozzle 21 and the bearings arranged on the 1241 glue nozzle 24 will keep walking on the curved surface of the object to which the glue is applied.

[0058] In order to ensure that the 320T glue nozzle 21 and the 1241 glue nozzle 24 can always maintain the same distance from the object being coated with glue when applying glue, in addition to the aforementioned installed bearings, a tension spring 19 is also connected to the rear end of the two glue nozzles. The upper ends of the two tension springs 19 are hung on the hooks set at the rear end of the glue nozzles, and the other ends are hung on the tension spring moving block at the lower end. The tension spring moving block is set in the slide groove set at the rear end of the component placement table 31. The tension spring moving block is set in the slide groove, and a tension spring hook is set on the tension spring moving block. Used for hanging the lower end of the tension spring 19; when the glue application construction moves, the tension spring 19 moves with the movement of the 320T glue nozzle 21 and the 1241 glue nozzle 24, and plays a role in pulling the glue nozzle, so that the 320T glue nozzle 21 and the 1241 glue nozzle 24 cannot freely tilt up when moving. In this way, under the support of the downward pulling force of the tension spring 19 and the horizontally movable bearings set at the front ends of the 320T glue nozzle 21 and the 1241 glue nozzle 24, no matter how the surface of the object being sprayed changes, the glue spraying distance can be guaranteed to be completely consistent from beginning to end.

[0059] Example 3: Operation of the present invention

[0060] There are a total of six electric sensors 25 arranged on the surface of the component placement table 31, four of which are symmetrically arranged on both sides, and the other two are arranged at the front end of the component placement table 31. After the operator places the automobile sunroof window frame 30 that needs to be glued on the component placement table 31, the two long sides of the sunroof window frame 30 are arranged front and back, the two short sides are arranged left and right, and the long side that needs to be glued is set at the back of the component placement table 31. After placing it, carefully check whether the inner frame of the automobile sunroof window frame 30 is outside the four electric sensors 25 symmetrically arranged on the left and right sides, that is, it is outside the four electric sensors 25, and the other two electric sensors 25 arranged at the front end should be at the outer edge of the front long side of the sunroof window frame 30; if it is placed correctly, the component is placed The workpiece in place indicator light 4 set on the table 31 will light up, indicating that the gluing can start. Then press the start button 26. At this time, the PLC in the controller sends an instruction to start the stepper motor 18, and drive the linear screw module 3 to rotate, and drive the 320T glue nozzle 21 and the 1241 glue nozzle 24 set on the two sliders 3A to move to the 320T glue output sensor 16 and the 1241 glue output sensor 17. Then start to execute the gluing instruction, energize the solenoid valves 28 and 27, start the 1241 glue pump 33 and the 320T glue pump 32, and start pushing the glue to the glue outlet. The linear screw module 3 rotates, and the slider 3A moves forward under the rotation of the thread to apply glue to the car sunroof window frame 30 that needs to be coated with glue.

[0061] During the gluing process, the operation indicator light 15 will always be on to remind others and avoid misoperation; due to the downward pulling force of the tension spring 19 and the support of the horizontally movable bearings set at the front ends of the 320T glue nozzle 21 and the 1241 glue nozzle 24, when the linear screw module 3 rotates and moves the two sliders 3A, and moves the 320T glue nozzle 21 and the 1241 glue nozzle 24 to apply glue, no matter how the arc surface of the object being sprayed changes, the glue spraying distance can be guaranteed to be completely consistent from beginning to end, and the high quality of the glue application can be guaranteed.

[0062] When the 320T glue nozzle 21 and the 1241 glue nozzle 24 reach the end point of glue coating, the tail glue discharge sensor on the left side of the vertical box back plate 34 on the back of the linear screw module 3 transmits information to the PLC controller. After receiving the information, the PLC immediately stops the power supply to the stepper motor 18 and the solenoid valve 27, cuts off the operation of the 1241 glue pump 33 and the 320T glue pump 32, and stops delivering glue. In this way, the 320T glue nozzle 21 and the 1241 glue nozzle 24 will stop at the end point of gluing, stop running and injecting glue, and wait for the next instruction to return to the glue discharge sensors 16 and 17 for the next gluing work.

[0063] Furthermore: The specific operation of the power box, circuit breaker, PLC controller, motor driver, and motor controller involved, as well as the structure and connection of the equipment itself are well known to ordinary technicians in this field. Therefore, the control circuits, specific control processes, equipment layout, etc. of these devices are also known to ordinary technicians in this field, and therefore, they will not be described in detail here.

[0064] Furthermore: The working process of the solenoid valve involved in the present invention is mainly to precisely control the delivery and stopping of glue liquid through program control. The solenoid valve and the air source pressure regulating valve adjust the pressure of the glue pump, and through the air source pressure regulating valve, the operation of the two glue pumps is controlled by the PLC program. These are all well known to ordinary technicians in this technical field and will not be described in detail here.

[0065] Furthermore, the hose universal joint is a product well known to ordinary technicians in this field, and is used to connect the glue delivery hose and the glue outlet nozzle of the gluing device of this application. When the gluing operation is carried out, the hose universal joint can rotate freely, thereby alleviating the problem of hose twisting that may be caused when the hose moves left and right.

[0066] Furthermore: the 1241 hose suspension balancer 9 and the 320T hose suspension balancer 13 suspend the rubber delivery hoses 1 and 2 respectively, and the 1241 hose suspension balancer 9 and the 320T hose suspension balancer 13 are hung on the balancer slide 5 and move left and right. Since the cables in the balancer can freely expand and contract under gravity, when the hoses move left and right for gluing, the hoses are suspended by the hose elevators 8, which can tighten or relax the rubber delivery hoses at any time, and together with the hose universal joints, prevent the rubber delivery hoses from twisting.

[0067] Furthermore: the power supply box 22 and the drive control box 23 are arranged under the component placement table 31. The power supply box is a 24V power supply and is equipped with a circuit breaker. The design and manufacture of the PLC controller, electric drive controller and motor controller arranged in the drive control box 23 are well-known technologies in the technical field and will not be further described here.
