Description

Technical Field

[0001] This utility model relates to the field of automatic detection and installation equipment, and in particular to an automatic detection and installation equipment for three-sided strips. Background Technology

[0002] With the continuous growth in automobile production and consumers' increasing demands for vehicle appearance quality and sealing performance, the installation accuracy of automotive glass accessories has become increasingly prominent, becoming a core pain point in the industry. Current traditional installation methods heavily rely on manual positioning, pressing, or applying sealant. This not only requires high personnel training costs but also leads to poor installation accuracy due to worker fatigue. This results in sealing failures such as water leakage, air leakage, and noise caused by misaligned sealing strips, as well as appearance defects caused by uneven installation and gaps in trim strips and chrome-plated parts. Furthermore, the adjustment of ordinary tooling is time-consuming, requiring repeated checks and corrections after installation, slowing down the production cycle. Utility Model Content

[0005] Furthermore, it has a centering positioning wheel and a clamping wheel, both of which are slidably connected to the base plate via slide rails.

[0006] Furthermore, the displacement sensor includes: a long-side strip measuring sensor and a narrow-side strip measuring sensor.

[0012] Furthermore, the pad mounting mechanism includes: a pad contour groove, an adjustment mechanism, and a lifting cylinder; the lifting cylinder is fixed on the base plate, the adjustment mechanism is fixed on the lifting cylinder, and the pad contour groove is connected to the adjustment mechanism.

[0013] The beneficial effects of this utility model are as follows: By constructing a closed-loop control system through a servo motor and a displacement sensor, the system can drive the edge strip contour blocks to slide independently relative to the base plate. During the sliding process, the position and attitude data of the glass are captured in real time, and the error is automatically compensated based on the data.

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 6 An automatic detection and installation device for three-sided strips includes: a displacement sensor, a servo motor, a strip contour block 7, a base plate 1, and a flat plate 2; the displacement sensor and the servo motor are both locked onto the base plate 1, the flat plate 2 is slidably connected to the base plate 1 via a slide rail 18, the strip contour block 7 is fixed on the flat plate 2, the servo motor is fixedly connected to the strip contour block 7, and the servo motor drives the strip contour block 7 to slide relative to the base plate 1.

[0018] As can be seen from the above description, the beneficial effects of this utility model are as follows: by constructing a closed-loop control system through a servo motor and a displacement sensor, the system can drive the edge strip contour blocks to slide independently relative to the base plate. During the sliding process, the position and attitude data of the glass are captured in real time, and the error is automatically compensated based on the data. This dynamic adjustment mechanism can effectively reduce the number of tooling debugging, shorten the preparation time, improve the accuracy of accessory installation, and reduce the rework rate caused by insufficient accuracy.

[0019] Furthermore, it has a centering positioning wheel 8 and a clamping wheel 9, both of which are slidably connected to the base plate 1 via a slide rail 18.

[0020] As described above, the two adjacent sides are fixed by the centering positioning wheel 8, and the clamping wheel 9 clamps the other two sides and moves them toward the position of the centering positioning wheel 8. The two work together to clamp and position the glass.

[0021] Furthermore, the displacement sensor includes: a long-side strip measuring sensor 3 and a narrow-side strip measuring sensor 4.

[0022] As can be seen from the above description, the position of one edge of the glass can be detected independently by the long edge measuring sensor 3 and the narrow edge measuring sensor 4, which makes the data more accurate.

[0023] Furthermore, the servo motors include: a long side strip adjustment servo motor 5 and a narrow side strip adjustment servo motor 6.

[0024] As described above, the movement of the contour block of one side of the strip can be independently controlled by the long side strip adjustment servo motor 5 and the narrow side strip adjustment servo motor 6, and the error can be automatically compensated in conjunction with the data of the displacement sensor.

[0025] Furthermore, it has a suction cup lifting mechanism 10 and a suction cup 11, with the suction cup 11 fixed on the suction cup lifting mechanism 10 and the suction cup lifting mechanism 10 locked on the base plate 1.

[0026] As can be seen from the above description, the glass can be moved up and down without damaging it by adsorbing the glass through the suction cup 11 on the suction cup lifting mechanism 10.

[0027] Furthermore, it has a support rod 12, which is locked onto the base plate 1. As described above, the support rod 12 is used to provide auxiliary support for the glass.

[0028] Furthermore, it has a pressure arm mechanism 14, which is locked onto the base plate 1.

[0029] As described above, the pressure arm mechanism 14 is used to press down the periphery of the glass so that the glass and the edge strip can fit together fully.

[0030] Furthermore, it has an accessory heating device 13, which is locked onto the base plate 1.

[0031] As described above, the accessory must be heated and softened in the accessory heating device 13 before being placed in the corresponding accessory conformer of the tooling.

[0032] Furthermore, it has a pad mounting mechanism 15, which is fixed on the base plate 1.

[0033] As can be seen from the above description, the pad installation mechanism 15 can be used for the positioning and installation of pads.

[0034] Furthermore, the pad mounting mechanism 15 includes: a pad contour groove 151, an adjustment position mechanism 152, and a lifting cylinder 153; the lifting cylinder 153 is fixed on the base plate 1, the adjustment position mechanism 152 is fixed on the lifting cylinder 153, and the pad contour groove 151 is connected to the adjustment position mechanism 152.

[0035] As described above, the pressure arm mechanism 14 presses the glass down to the accessory installation position, while the lifting cylinder 153 pushes the accessory to fit against the glass, ensuring that the adhesive on the accessory is cured or the buckle is fully engaged.

[0036] Please refer to Figures 1 to 6 Embodiment 1 of this utility model is as follows: An automatic detection and installation device for three-sided strips includes: a displacement sensor, a servo motor, a strip contour block 7, a base plate 1, and a flat plate 2; the displacement sensor and the servo motor are both locked onto the base plate 1, the flat plate 2 is slidably connected to the base plate 1 via a slide rail 18, the strip contour block 7 is fixed on the flat plate 2, the servo motor is fixedly connected to the strip contour block 7, and the servo motor drives the strip contour block 7 to slide relative to the base plate 1.

[0037] In this embodiment, the centering positioning wheel 8 and the clamping wheel 9 are slidably connected by the slide rail 18. Together, they can position two adjacent edges of the glass and drive the other two edges towards the positioning edge, thus completing the clamping and positioning of the glass. The displacement sensors are divided into a long edge measuring sensor 3 and a narrow edge measuring sensor 4, which can independently detect the position of the corresponding edge of the glass to ensure data accuracy. The servo motors are correspondingly set with a long edge adjustment servo motor 5 and a narrow edge adjustment servo motor 6, which can independently control the movement of the edge strip contour block 7 on the corresponding edge, automatically compensating for errors in conjunction with the displacement sensor data. Simultaneously, the base plate 1 is also fitted with a suction cup lifting mechanism 10, a support rod 12, a pressure arm mechanism 14, an accessory heating device 13, and a pad mounting mechanism 15. The suction cup 11 is fixed to the suction cup lifting mechanism 10, enabling the glass to move up and down without damaging it. The support rod 12 assists in supporting the glass. The pressure arm mechanism 14 can press down on the periphery of the glass to ensure it fully conforms to the edge strip. The accessory heating device 13 can heat and soften the 3mm of the accessory. The adhesive is used for subsequent placement in the tooling contouring. The pad mounting mechanism 15 consists of a lifting cylinder 153 fixed on the base plate 1, an adjusting position mechanism 152 fixed on the lifting cylinder 153, and a connected pad contouring groove 151. When the pressure arm presses the glass down to the accessory mounting position, the lifting cylinder 153 pushes the accessory to fit with the glass, ensuring that the adhesive is cured or the clips are fully engaged.

[0038] In this embodiment, the side without displacement sensors and servo motors is the fixed side. The displacement sensors on the two sides adjacent to the fixed side are long side strip measurement sensors 3, and the displacement sensor on the side opposite to the fixed side is a narrow side strip measurement sensor 4. The servo motors used to drive the two sides adjacent to the fixed side are long side strip left and right adjustment servo motors 5, and the servo motors used to drive the side opposite to the fixed side are narrow side strip adjustment servo motors 6.

[0039] In this embodiment, the contour block on the fixed side is a fixed contour block 16, which is locked to the base plate 1 by an I-beam. The fixed side and the side adjacent to it are equipped with a centering positioning wheel 8, and the other two adjacent sides are equipped with clamping wheels 9. Since the fixed side is equipped with a centering positioning wheel 8, the relative position of the fixed contour block 16 and the glass can be determined. The edge strip accessories of the other three sides are connected to each other. After the clamping wheel 9 clamps the glass, the relative position of the edge strip contour block 7 and the glass is adjusted by setting a displacement sensor and a servo motor.

[0040] In this embodiment, a predetermined post 17 is also provided, through which the glass is pre-positioned.

[0041] Working principle: First, the glass is manually placed on the support rod 12, and accessories (nails, pads, brackets, edge strips, etc.) are placed before pressing the start button. Some accessories need to be softened by heating in the heating device before being placed in the corresponding accessory contouring tool. Then, the centering positioning wheel 8 fixes two adjacent sides, and the clamping wheel 9 clamps the other two sides, bringing them closer to the centering positioning wheel 8. The two work together to clamp and position the glass. The displacement sensor pushes out to measure the edge of the glass, measuring the deviation between the actual position and the theoretical value. The data is transmitted to the PLC in real time. The PLC generates compensation instructions through an algorithm and sends them to the servo controller. The servo controller instructs the servo motor to drive the edge strip contouring block 7 and the plate 3 corresponding to the edge strip contouring block 7. The slide rail 18 moves relative to the base plate 1 to precisely adjust to the target position. Next, the suction cup lifting mechanism 10 rises to adsorb the glass, the support rod 12 descends, the centering positioning wheel 8 and clamping wheel 9 are released, and the glass descends with the suction cup lifting mechanism 10. The pressure arm mechanism 14 presses the glass down to the accessory installation position. At the same time, the lifting cylinder 153 pushes the accessories (nails, pads, brackets, etc.) to adhere to the glass. The system maintains constant pressure for 5-10 seconds to ensure that the adhesive is cured or the clips are fully engaged. Finally, the lifting cylinder 153 retracts, the pressure arm mechanism 14 returns to its original position, the suction cup lifting mechanism 10 raises the glass to the initial height, the support rod 12 rises to assist in bearing the weight, the suction cup 11 breaks the vacuum to release the glass, and the finished product is manually removed, completing a single cycle.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
