Description

Windshield prime coat frock

Technical Field

The utility model relates to an automotive production technical field especially relates to a windshield first coat frock.

Background

At present, the automobile windshield is generally fixed by adopting a polyurethane adhesive bonding mode. Before the glass is adhered to the car body, the lap joint surface of the car body is coated with a primer. The base coat is an activator, and mainly improves the bonding strength and reliability of the glass cement. In the production process, glass cement is applied to glass, and a base coat is coated on the corresponding bonding position of the vehicle body. The glass cement is processed by a robot, and the cement track is stable. The path of the base coat is generally smeared by workers with a hairbrush, the stability of the path is very poor, if the base coat deviates from the theoretical path, the glass cement cannot be contacted with the base coat, the glass cement is easily bonded insecurely, and even the glass falls off; in order to ensure the uniformity and stability of the base coat, an operator usually uses a brush to operate slowly and repeatedly, the working efficiency is low, the linearity of the base coat is still difficult to ensure, and the consistency effect of the base coat is poor; in the operation process, the brush is dipped in the black base coat, and the base coat is easy to drip and pollute the car body. Patent CN211186224U discloses a frock structure that windshield prime coat brush was glued before car, including prime coat bottle, brush head, spacing protruding muscle are connected in the bottom of prime coat bottle, rely on the automobile body through spacing protruding muscle and keep off window frame tang assistance-localization real-time before, and the location effect is not good enough, if the skew still easily causes the skew theoretical orbit of prime coat about the contact position of spacing protruding muscle and panel beating in the use, causes the prime coat uniformity poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a windshield prime coat frock that prime coat orbit uniformity is good is provided.

The utility model discloses a realize solving above-mentioned technical problem through following technical means: the windshield prime coat tool comprises a brush handle (1), a brush head (2), a roller connecting mechanism (3) and a positioning roller (4); the brush head (2) is fixedly connected to the bottom of the brush handle (1); the roller connecting mechanism (3) is fixedly connected to one side of the brush handle (1); at least one positioning roller (4) is arranged on the roller connecting mechanism (3), and the positioning roller (4) rotates around the central axis of the positioning roller and is connected to the roller connecting mechanism (3); and a positioning groove (41) is formed in the periphery of the outer ring of the positioning roller (4).

The brush handle and the brush head are similar to the white board pen in structure, and the bottom coat can be injected into the upper part of the brush handle, so that the problem that the bottom coat is easy to drip because the brush needs to be dipped in the bottom coat continuously is solved.

As the optimized technical scheme, the roller connecting mechanism (3) comprises a connecting arm (31) and a rotating shaft (32), the connecting arm (31) is fixedly connected to one side of the brush handle (1), the rotating shaft (32) is fixedly connected to the bottom of the connecting arm (31), and the positioning roller (4) is rotatably connected to the outer ring of the rotating shaft (32). Simple structure and convenient use.

As an optimized technical scheme, the roller connecting mechanism (3) is provided with two rotating shafts (32), and the two rotating shafts (32) are arranged in bilateral symmetry relative to the brush handle (1); two positioning rollers (4) are installed on the roller connecting mechanism (3), and the two positioning rollers (4) are respectively rotatably connected to the outer rings of the two rotating shafts (32) and located at the same height position. Two positioning rollers form a roller group, so that the tool is more stable.

As an optimized technical scheme, the width of the positioning groove (41) from the bottom of the inner ring groove to the notch of the outer ring groove is gradually increased. Make things convenient for the constant head tank embedding panel beating in to make things convenient for the high position location of location gyro wheel.

As an optimized technical scheme, the central axis of the positioning roller (4) is perpendicular to the bottom surface of the brush head (2), and the height position of the upper end of the bottom of the inner ring groove of the positioning groove (41) is the same as that of the bottom surface of the brush head (2). The metal plate brush is suitable for metal plates with plane structures, is widely applied, and when the metal plates are of other structures, the positioning idler wheel and the brush head can adopt other corresponding position relations.

The utility model has the advantages that:

1. the consistency of the trace of the bottom coating smeared by the tool is good, the trace is not easy to distort, and the trace of the bottom coating is easier to keep consistent with the theory; the operation is simple and quick, the experience of workers is not needed, and the working efficiency is improved.

2. The problem that the brush is required to be continuously dipped in the base coat to cause the base coat to easily drip is solved.

3. Two positioning rollers form a roller group, so that the tool is more stable.
