Description

Technical Field

[0001] The utility model relates to the field of vehicles, and particularly relates to an automatic primer brushing device for the bonding area of a spoiler sealing strip of a passenger car. Background Art

[0002] The spoiler of a passenger car is basically a plastic part. A sealing strip needs to be pasted between the spoiler and the whole vehicle body to ensure the sealing between parts. The sealing strip and the spoiler need to be adhesively fixed. Therefore, before bonding, the bonding area of the spoiler needs to be brushed with primer. The traditional way of brushing primer on the bonding area of the spoiler sealing strip is usually manual operation with a primer brush. The primer is a transparent liquid containing fluorescent agent inside. After brushing, it will volatilize quickly, and the chemical substances remaining on the spoiler after volatilization are the key to bonding the sealing strip. Since it is impossible to judge whether the primer is brushed on the product by visual inspection, it needs to be irradiated with an ultraviolet lamp to show blue or detected by a fluorescence sensor. Manual brushing of primer is not only troublesome and time-consuming, but also prone to local missed brushing. Summary of the Utility Model

In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0026] Please refer to Figure 1 、 Figure 2 As shown, an automatic primer brushing device for the bonding area of a passenger car spoiler seal strip includes a tire mold, a primer brushing mechanism, a fluorescence sensor, and a PLC controller. The tire mold is used to carry the workpiece 1, the primer brushing mechanism is used to brush primer on the workpiece 1 placed on the tire mold, and the fluorescence sensor is used to detect the workpiece 1 after primer brushing to avoid missed brushing; the tire mold, the primer brushing mechanism, and the fluorescence sensor are all communicatively connected to the PLC controller.

[0027] The tire mold is slidably installed on the workbench 2 and can reciprocate between the workpiece loading / unloading position and the primer brushing position; when the tire mold carrying the workpiece 1 moves to the primer brushing position, the PLC controller can control the primer brushing mechanism to apply the primer on the surface of the workpiece 1 along a preset trajectory, and detect the workpiece 1 after the primer is applied through the fluorescence sensor, so as to realize the automatic operation of the device; among them, the fluorescence sensor is arranged above the primer brushing position, and the PLC controller is arranged below the workbench 2, which is not specifically shown in the figure.

[0028] Specifically, as Figure 2 、 Figure 3 shown, the tire mold in the embodiments of the present utility model includes a bottom plate 3, a profiling base 4, and a pressing component. The bottom plate 3 is slidably connected to the workbench 2 through common sliding structures such as slide rails and bull's-eye universal wheels. The profiling base 4 is fixedly installed on the bottom plate 3. A loading groove that is profiled with the workpiece 1 is formed at the top of the profiling base 4. An in-place detector 5 communicatively connected to the PLC controller is arranged in the loading groove to detect whether the workpiece 1 is placed in place. The profiling base 4 can be an integral base with a profiling groove at the top, or can be formed by enclosing a plurality of support blocks with profiling grooves at the top as Figure 3 shown, and the present application does not make excessive limitations.

[0029] The clamping component is used to clamp and fix the workpiece 1 placed in the bearing groove. Specifically, the clamping component in the embodiment of the present utility model includes a fixed clamping block 6, a moving clamping block 7, and a driving cylinder 8. Among them, the fixed clamping block 6 and the moving clamping block 7 are oppositely arranged on both sides of the bearing groove, and clamping grooves for clamping and cooperating with the workpiece 1 are provided on the opposite sides of the fixed clamping block 6 and the moving clamping block 7. The fixed clamping block 6 and the driving cylinder 8 are both fixedly arranged on the bottom plate 3. The moving clamping block 7 is fixedly connected to the driving rod of the driving cylinder 8. The moving clamping block 7 can move in the direction of approaching or departing from the fixed clamping block 6 under the drive of the driving cylinder 8, so as to clamp or release the workpiece 1. The driving cylinder 8 is communicatively connected to the PLC controller, and can automatically clamp the workpiece 1 after the workpiece 1 is placed in place, and can also automatically release the workpiece 1 when the fluorescence sensor detects that the workpiece 1 needs to be taken out.

[0030] On one side of the bottom plate 3 facing the pick / place position, a pressing component is further provided. The pressing component includes a hinge seat 9 and a pressing plate 10. The hinge seat 9 is fixedly arranged on the bottom plate 3.

After the workpiece 1 is placed in place, the pressing plate 10 can be flipped to abut against the top of the workpiece 1 to strengthen the positioning of the workpiece 1. On both sides of the pressing plate 10, pressing plate position detectors 11 communicatively connected to the PLC controller are provided, which can detect the current position of the pressing plate 10 and remind the process personnel to flip the pressing plate 10.

[0031] Further, in order to accurately position the mold, in the embodiment of the present utility model, a V-shaped positioning groove 12 is opened on one side of the bottom plate 3 facing the primer coating position, and a positioning post 13 is correspondingly arranged on the workbench 2; a positioning pin 14 is provided on the bottom plate 3, and a positioning hole is correspondingly opened on the workbench 2; when the mold moves to the primer coating position, the positioning post 13 can abut against and limit the V-shaped positioning groove 12 to ensure that the mold accurately stays at the primer coating position, and then the positioning pin 14 can be inserted into the positioning hole to lock and position the bottom plate 3 and the workbench 2.

[0032] In order to improve the equipment utilization rate, the mold can be detachably installed on the workbench 2. By replacing different models of molds, the automatic primer coating of different models of workpieces 1 can be realized; a mold change detector 15 for detecting the mold model is provided on the workbench 2. The mold change detector 15 is communicatively connected to the PLC controller, so that the PLC controller can select the control mode corresponding to the workpiece 1 according to the mold model.

[0033] Specifically, such as Figure 4As shown in the figure, the primer coating mechanism in the embodiment of the present utility model includes a primer coating bucket 16, a primer coating brush head 17, and a multi-degree-of-freedom robotic arm 18. The primer coating bucket 16 contains a primer coating agent with a fluorescent agent. The primer coating brush head 17 is installed on the multi-degree-of-freedom robotic arm 18 and is in fluid communication with the primer coating bucket 16 through a hose (not shown in the figure). A peristaltic pump 19 is connected between the primer coating bucket 16 and the primer coating brush head 17. Both the peristaltic pump 19 and the multi-degree-of-freedom robotic arm 18 are communicatively connected to the PLC controller, ensuring that the peristaltic pump 19 can pump the primer coating agent to the primer coating brush head 17 synchronously with the brushing action of the multi-degree-of-freedom robotic arm 18. Further, the primer coating mechanism further includes a moisturizing bottle 20. After the brushing is completed, the multi-degree-of-freedom robotic arm 18 can insert the primer coating brush head 17 into the moisturizing bottle 20 to keep the primer coating brush head 17 moist through the volatilization of the primer coating agent, avoiding the drying of the primer coating brush head 17 caused by long-term shutdown, which may lead to insufficient coating of the first workpiece after startup.

[0034] Further, the primer coating bucket 16 is placed on the weighing platform of a weighing device 21. The weighing device 21 is communicatively connected to the PLC controller, which can remind the process personnel to replace the primer coating bucket 16 in time before the primer coating agent is used up. A sealing cover 22 is provided at the opening at the top of the primer coating bucket 16, and the hose passes through the sealing cover 22. A slide rail 23 is vertically established beside the primer coating bucket 16, and a slider 24 is slidably arranged on the slide rail 23. The sealing cover 22 is fixedly connected to the slider 24, enabling the sealing cover 22 to move up and down along the slide rail 23. When the remaining primer coating agent in the primer coating bucket 16 is insufficient, the sealing cover 22 can be moved upward to replace the primer coating bucket 16.

[0035] The specific operation process of the embodiment of the present utility model is as follows:

[0036] (1) After moving the tire mold to the pick / place position, place the workpiece 1 on the tire mold and fix the workpiece 1; (2) Move the tire mold carrying the workpiece 1 to the primer coating position and lock and position the tire mold; (3) Start the equipment, and the multi-degree-of-freedom robotic arm 18 moves the primer coating brush head 17 to the primer coating area of the workpiece 1 and applies the primer coating agent on the surface of the workpiece 1 along a preset trajectory; (4) After the primer coating agent is applied, a fluorescence sensor detects whether there is an uncoated area on the workpiece 1; (5) After the detection is completed, the multi-degree-of-freedom robotic arm 18 inserts the primer coating brush head 17 into the moisturizing bottle 20. If the detection result is okay, move the tire mold back to the pick / place position and take out the workpiece 1 coated with the primer coating agent. If an uncoated area is detected on the workpiece 1, the equipment will alarm and the workpiece 1 cannot be taken out, and the process personnel need to confirm on-site.
