Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a positioning mechanism for applying adhesive to automotive windshields. Background Technology

[0002] The windshield of a car closely links the automotive industry (mechanical manufacturing) with the glass industry (light industry). The windshield must not only protect the occupants but also provide airtightness and good sound insulation. The installation quality of the windshield directly affects the sealing and safety of the entire vehicle. One important step in the installation of the windshield is applying adhesive to the edges of the windshield.

[0003] Chinese Patent No. CN206315993U discloses a positioning structure for a windshield side edge adhesive coating device, including a base, a main shaft rotatably connected to the base, and an annular support plate connected to the upper end of the main shaft. The positioning structure includes several fixing rings circumferentially fixed to the side of the support plate, and several fixing discs slidably connected to the support plate. A circular rubber diaphragm is provided between the fixing discs and the fixing rings, and the outer edge of the rubber diaphragm is circumferentially fixed to the fixing rings. The fixing discs are fixed to the middle of the rubber diaphragm. The main shaft is provided with an operating component that can simultaneously drive the fixing discs downward. This device can fix the windshield stably and is easy to operate.

[0004] However, the above technical solution has the following shortcomings: when the positioning structure is used to adsorb and support the windshield of a car, the suction cups are distributed in a ring array. This distribution method is not suitable for windshields of general shapes. In addition, the position of the suction cups is fixed and cannot be adjusted according to the size of the glass, which reduces the applicable scope of the positioning structure. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a positioning mechanism for applying adhesive to automotive windshields, improving the distribution of the force support structure for the windshield, and enabling the support effect to be adjusted according to the size of the glass, thereby expanding the scope of application.

[0006] The present invention provides a positioning mechanism for applying adhesive to automotive windshields, comprising a mounting base and an adsorption support mechanism. The mounting base has a support column, and the support column has a mounting plate. The adsorption support mechanism includes eight sub-supports of different lengths with multiple linearly distributed mounting holes, a suction cup on each sub-support, a connecting nozzle on the suction cup, and an adjustment component on the connecting nozzle. The eight sub-supports are arranged in a divergent pattern, with adjacent sub-supports dividing the circumference at a 45° angle. The adjustment component includes a locking plate on the suction cup, a fastening bolt passing through the mounting holes and the locking plate, and a nut threaded onto the fastening bolt. The nut and the sub-supports are in contact.

[0007] Preferably, the length gradient design of the sub-brackets is four long and four short, with the long sub-brackets extending to the four corners of the windshield and the short sub-brackets supporting the straight edge areas.

[0008] Preferably, the mounting base is provided with two negative pressure generators, which are connected to the suction cups on both sides through connecting nozzles.

[0009] Preferably, the suction cups are asymmetrically distributed.

[0010] Preferably, a base is provided below the mounting base, and a rotating shaft is coaxially provided on the mounting base, the rotating shaft extending into the interior of the base and rotatably connected.

[0011] Preferably, the base is provided with a drive assembly, which includes a mounting bracket inside the base, a motor mounted on the mounting bracket, a first gear connected to the motor drive, and a second gear coaxially mounted on a rotating shaft; the first gear and the second gear are meshed together.

[0012] Preferably, the mounting base is provided with four rollers arranged in a circular array, and the rollers are rotatably mounted on the base.

[0013] Preferably, the base is provided with a door and heat dissipation holes.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The present invention, through the structural design of the eight sub-supports in the adsorption support mechanism, can uniformly support the four corners and straight edges of the windshield, ensuring the stability of the windshield, adapting to conventional windshield shapes, and through the set locking plate, fastening bolts, nuts and mounting holes, can adjust the position and angle of the suction cup to support windshields of different sizes, expanding the applicability of the device and having good practicality; 2. This utility model controls the adsorption and detachment of the suction cup by setting a negative pressure generator, avoiding the problem that it is not easy to detach after manually achieving negative pressure adsorption.

[0016] Example 1: As Figure 1 - Figure 4 As shown in the figure, the positioning mechanism for applying adhesive to automotive windshield glass proposed in this embodiment includes a mounting base 1 and an adsorption support mechanism; a support column 2 is provided on the mounting base 1, and a mounting plate 3 is provided on the support column 2. The adsorption support mechanism includes eight brackets 4 with mounting holes 11 of different lengths and multiple linear arrays, suction cups 5 mounted on the brackets 4, connecting nozzles 6 mounted on the suction cups 5, and adjustment components mounted on the connecting nozzles 6. The eight brackets 4 are arranged in a divergent pattern, with adjacent brackets 4 evenly dividing the circumference at a 45° angle. The length gradient of the brackets 4 is designed as four long and four short, with the long brackets 4 extending to the four corners of the windshield and the short brackets 4 supporting the straight edge area. The adjustment components include a locking plate 8 mounted on the suction cups 5, fastening bolts 9 passing through the mounting holes 11 and locking plate 8, and nuts 10 threaded onto the fastening bolts 9. The nuts 10 and the brackets 4 are abutted together. The suction cups 5 are asymmetrically distributed. Two negative pressure generators 7 are mounted on the mounting base 1, and the two negative pressure generators 7 are connected to the suction cups 5 on both sides through the connecting nozzles 6.

[0017] In this embodiment, the connector 6 is connected to the negative pressure generator 7 via a branch pipe (not shown), enabling the negative pressure generator 7 to control the adsorption and detachment of the suction cup 5. This avoids the problem of difficulty in detachment after manual negative pressure adsorption. When the windshield is placed on the suction cup 5, the negative pressure generator 7 causes the suction cup 5 to adsorb the windshield. The locking plate 8, fastening bolts 9, and nuts 10 can control and adjust the installation angle of the suction cup 5, allowing the suction cups 5 at different positions to match the glass installation angle, ensuring the stability of the windshield during placement. Furthermore, the size and distribution design of the eight sub-supports 4 can provide uniform force support to the four corners and straight edges of the windshield, ensuring the stability of the windshield. It can also adapt to support conventional windshield shapes. The position of the suction cup 5 can be adjusted through the mounting holes 11 to support windshields of different sizes, expanding the applicability of the device and demonstrating good practicality.

[0018] It should be noted that the windshield is placed using visual guidance positioning technology. An industrial 3D camera is installed above or to the side of the adhesive application station to capture the position and outline of the windshield in real time. The camera acquires images of the glass, and the vision system calculates the glass's current precise position and rotation angle through image processing algorithms. The calculated actual position is compared with the preset theoretical position to obtain the deviation value. Based on the deviation value, the robot's movement trajectory or final placement position after grasping the glass is corrected, so that the four corners of the glass are located on the suction cups 5 of the long support 4. This technology is a mature existing technology and has been applied in the actual production of automobiles.

[0019] Example 2: Figure 1 and Figure 4 As shown, this embodiment proposes a positioning mechanism for applying adhesive to automotive windshields. Compared to Embodiment 1, in this embodiment, a base 12 is provided below the mounting base 1, and a rotating shaft 13 is coaxially provided on the mounting base 1. The rotating shaft 13 extends into the interior of the base 12 and is rotatably connected. A drive assembly is provided inside the base 12. The drive assembly includes a mounting bracket 14 provided inside the base 12, a motor 15 provided on the mounting bracket 14, a first gear 16 drivenly connected to the motor 15, and a second gear 17 coaxially provided on the rotating shaft 13. The first gear 16 and the second gear 17 are meshed together.

[0020] The mounting base 1 is provided with four rollers 18 arranged in a circular array. The rollers 18 are rotatably mounted on the base 12, which is provided with a door 19 and heat dissipation holes 20.

[0021] In this embodiment, when applying adhesive to the windshield, the motor 15 drives the first gear 16 to rotate. The first gear 16 and the second gear 17 mesh and transmit power, causing the rotating shaft 13 to drive the mounting base 1 to rotate slowly and uniformly. The rollers 18 reduce the friction between the mounting base 1 and the base 12, reducing energy consumption and wear. In turn, the mounting base 1 drives the windshield to rotate to achieve orientation adjustment, so as to apply adhesive to different positions of the windshield and improve the practicality of the equipment.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
