Description

Technical Field

[0001] The invention relates to the technical field of mechanical tooling, and in particular to an automatic windshield auxiliary hanger. Background Art

[0002] There are three main types of windshield installation in automobile assembly workshops: manual, automatic, and semi-automatic. Automatic and semi-automatic methods require automated hoists. The existing automated hoist structure has the following defects:

[0003] 1) The manual method requires the operator to walk to the windshield gluing station, carry the windshield to the installation station, and lift the glass to install it at an angle. The labor intensity is high, and the success rate of windshield installation varies depending on the proficiency.

[0004] 2) The fully automated lifting device needs to accurately place the windshield on the vehicle, which requires huge investment in position calibration, such as 3D vision guidance and auxiliary positioning tooling.

[0005] 3) Semi-automatic hoists generally use cylinders and belts to lift the windshield to the top fixed position of the hoist. When the hoist reaches the installation position above the vehicle, the operators on both sides overcome the cylinder tension with their hands, pull down the windshield and the partial movable hoist, place the windshield at the installation position, press the release button to release the windshield, and assist the partial movable hoist to lift to the top fixed position of the hoist. During the entire installation process, the operators on both sides need to pull down and hold the handles of the partial movable hoist tightly, which is labor-intensive; in order to adapt to windshields of different weights, complex air circuits need to be designed, and they need to be switched correctly and in time, otherwise the glass may fall off; due to the height of the operator, it is impossible to adapt to a higher vehicle body height. Summary of the invention

[0006] In response to the above technical problems, the present invention discloses an automated windshield auxiliary hanger, which solves the problem of pulling down and requiring continuous hand holding during the installation process of a semi-automatic hanger; it can further adapt to windshields of different weights and can also adapt to taller vehicle bodies.

[0010] The driving mechanism on the fixed frame of the spreader drives the movable frame through the driving connector, and is assisted by the balancer to lift the movable frame of the spreader. The movable frame of the spreader is positioned when it reaches the top through the positioning fixture and the guide mechanism on the fixed frame of the spreader.

[0011] This technical solution adopts a split-type sling. The fixed frame of the sling, and the balancer, positioning fixture, driving mechanism and guiding mechanism located thereon constitute the fixed part of the sling. The movable frame of the sling and the suction cup module located thereon constitute the movable part of the sling. The fixed part of the sling can be installed on various forms of motion devices. The fixed part of the sling is connected to the movable part of the sling through a belt and a balancer wire rope. The movable part of the sling is driven by the driving mechanism, and assisted by the balancer, so that the movable part of the sling is raised and lowered, thereby driving the glass sucked by the suction cup module to rise and fall. The lifting and lowering are more stable and do not require pulling down and continuous hand holding. In addition, when reaching the top, the movable part of the sling is accurately positioned by the guiding mechanism and the positioning fixture when it rises to the top. Among them, the outer contours of the movable frame part of the guiding mechanism, the positioning fixture and the movable frame part of the sling are tightly attached to each other on multiple surfaces to achieve positioning.

[0012] As a further improvement of the present invention, the driving mechanism includes a belt driving mechanism and a pulley, the driving connecting member is a belt, the belt driving mechanism is connected to the belt through the pulley, and the belt drives the movable frame of the sling to rise and fall.

[0013] As a further improvement of the present invention, the belt driving mechanism includes a reduction motor, the reduction motor is connected to a pulley, and the pulley drives the belt to rotate, thereby driving the movable frame of the sling to rise and fall.

[0014] As a further improvement of the present invention, the movable frame of the sling is provided with an operating handle, the operating handle is provided with buttons, the buttons include a drive button and a suction cup button, the drive button is electrically connected to the reduction motor, and the suction cup button is electrically connected to the vacuum control module of the suction cup module.

[0015] As a further improvement of the present invention, a hand handle is provided on the movable frame of the sling.

[0016] As a further improvement of the present invention, the balancer includes a spiral tube, and the steel wire rope is located in the middle of the spiral tube.

[0017] As a further improvement of the present invention, the balancers are located on both sides of the sling fixed frame, and the balancers on both sides of the sling fixed frame are respectively connected to both sides of the sling movable frame through steel wire ropes.

[0018] As a further improvement of the present invention, the suction cup module is located at the bottom of the movable frame of the sling, and a detection switch is also provided at the bottom of the movable frame of the sling.

[0019] As a further improvement of the present invention, the guide mechanism is a guide bar, which includes a fixing portion fixedly connected to the hanger fixing frame and a guide portion, the guide portion and the fixing portion form an obtuse angle, and the guide portion extends obliquely outward.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By adopting the technical solution of the present invention, under the premise of satisfying the adjustment freedom when installing the windshield, the movable lifting device part can be automatically raised and lowered, and the whole lifting process is automated, without the need for the operator to pull it down by hand or assist in raising it by hand. It can be accurately positioned at the top and the position and twist can be greatly adjusted at the bottom; it is driven by a reduction motor and can be adapted to windshields of all weight specifications of the final assembly line; since there is no need to pull the lifting device down by hand, it can be adapted to vehicles of all height specifications of the final assembly line.
