Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile glass processing equipment, specifically to a centering device. BACKGROUND

[0002] In the field of modern automobile manufacturing, automobile windshield glass, as an important part of the vehicle, not only bears the role of protecting the people inside from the invasion of wind and sand, rain and the like outside, but also plays a crucial role in the structural integrity and safety of the vehicle. During the production and processing of automobile windshield glass, it needs to go through a series of complex processes, among which the gluing process is particularly critical.

[0003] The main purpose of the gluing process is to coat a layer of glue on the edge of the automobile windshield glass so as to firmly install it on the automobile body frame. However, in the actual production process, the automobile windshield glass will go through multiple processing links before being transmitted to the gluing process. In these links, the position angle of the windshield glass placed on the conveyor belt may differ, for example, when the workers or automated equipment place the windshield glass on the conveyor belt after the end of the previous process, due to the limitation of operation precision, the placement position and angle of the glass may not be completely consistent. In addition, during the operation of the conveyor belt, the windshield glass may be displaced due to factors such as mechanical vibration, relaxation or tension change of the conveyor belt.

[0004] When the automobile windshield glass reaches the gluing process, it is usually grabbed from the conveyor belt by suction and transferred into the gluing equipment. However, due to the existence of the above-mentioned position angle and displacement deviation, it is difficult to ensure that the windshield glass is always in the precise position required by the gluing equipment when the suction grabbing device moves it into the gluing equipment. This deviation may cause the glue head of the gluing equipment to not accurately align with the predetermined gluing area of the windshield glass, thereby affecting the uniformity and integrity of the gluing. If the gluing is uneven or missing, it may lead to insufficient bonding strength between the windshield glass and the body frame, thereby affecting the overall quality and safety of the automobile.

[0005] In addition, the efficiency of the gluing process will also be affected by this deviation. In order to ensure the quality of gluing, the operator may need to spend extra time and effort to adjust the position of the windshield glass, or perform additional inspection and remedial work after gluing, which undoubtedly increases the production cost and production cycle.

[0006] Therefore, how to solve the problem of position deviation of automobile windshield glass in the gluing process and improve the precision and efficiency of gluing has become a technical problem to be solved in the field of automobile windshield glass production. INVENTION CONTENTS

The base frame 1 is connected to the side frames 2 on both sides, and a width adjustment structure 3 is provided between the bottom of the base frame 1 and the two side frames 2 to support the bottom of the car windshield and limit its two ends. A limiting structure 4 is installed on the top of the base frame 1 to limit the two sides of the car windshield to be located in the central area of ​​the base frame 1.

[0022] The base frame 1 and the side frame 2 form a cross-shaped structure when viewed from above, which is convenient for the width adjustment structure 3 and the limiting structure 4 to limit the four sides of the car windshield, so that it is centered and can be adsorbed and grasped during the adhesive application process.

[0023] The width adjustment structure 3 includes a support part and a limiting part. The support part includes a transverse electric telescopic rod 301, a mounting frame 302, a first longitudinal electric telescopic rod 303, a recessed frame 304, and a support column 305. A transverse electric telescopic rod 301 is staggered at the bottom of the base frame 1, and a mounting frame 302 is rolled to the end of each transverse electric telescopic rod 301. The mounting frames 302 are slidably connected to the top of a side frame 2. A first longitudinal electric telescopic rod 303 is installed on the bottom of each mounting frame 302 near the base frame 1. A recessed frame 304 is connected to the end of each first longitudinal electric telescopic rod 303 through the top of the mounting frame 302. A support column 305 for supporting the end face of the car windshield is connected to the end face of the recessed area of ​​each recessed frame 304.

[0024] The limiting part includes a second longitudinal electric telescopic rod 306, a protrusion 307, and a first limiting post 308. Each mounting bracket 302 has a second longitudinal electric telescopic rod 306 installed on the side of its bottom away from the base frame 1. Each end of the second longitudinal electric telescopic rod 306 passes through the top of the mounting bracket 302 and is connected to a protrusion 307. Each protrusion 307 has a first limiting post 308 connected to the end face of the protruding area for contacting and limiting the two ends of the car windshield.

[0025] The limiting structure 4 includes a servo motor 401, a conveyor belt mechanism 402, a slide 403, a limiting slide rail 404, a limiting frame 405, and a second limiting post 406. The conveyor belt mechanism 402 is installed on the top of the base frame 1, and the servo motor 401 for driving the transmission of the conveyor belt mechanism 402 is provided at the bottom of the base frame 1. A slide 403 is symmetrically connected to each side of the conveyor belt mechanism 402, and a limiting slide rail 404 is slidably connected to each side of the bottom of each slide 403. The limiting slide rail 404 is installed on the top two sides of the base frame 1 to assist and limit the movement of the two slides 403 towards or away from each other. A limiting frame 405 is installed on the top of each slide 403, and a second limiting post 406 for limiting the movement of the windshield of the car is connected to the end of each limiting frame 405.

[0026] The limiting frame 405 is configured as a horizontal "E"-shaped structure, and each end of the limiting frame 405 is connected to a second limiting column 406.

[0027] Working principle: It is designed to work in conjunction with a robotic arm to solve the problem of positional deviation of the windshield in the adhesive application process, ensuring that the windshield can be accurately placed in the fixed position of the adhesive application equipment, thereby improving the adhesive application quality and efficiency.

[0028] In the production and processing of automotive windshields, after the windshield completes the previous process, it is conveyed to the adhesive application area via a conveyor belt. At this point, the robotic arm begins to function, grabbing the windshield from the conveyor belt and transferring it to the centering device. Before this operation, the device makes corresponding adjustments based on the specific dimensions of the windshield to be processed. Specifically, the lateral electric telescopic rod 301 drives the two mounting brackets 302 on the side frame 2 to move closer together, so that the distance between the two first limiting posts 308 on the mounting brackets 302 is slightly larger than the size of the windshield, thereby providing sufficient space for the windshield while ensuring that it can be stably limited. At the same time, the first... The longitudinal electric telescopic rod 303 extends, pushing the recessed bracket 304 and the support column 305 upwards by a certain distance to better support the windshield. In addition, the second longitudinal electric telescopic rod 306 also moves, pushing the protruding bracket 307 and the first limiting column 308 upwards, so that the height of the first limiting column 308 is higher than the height of the support column 305. At this time, the robotic arm places the windshield it has grabbed onto the support column 305 for support. At the same time, the lateral electric telescopic rod 301 continues to drive the two mounting brackets 302 to move closer to each other, so that the first limiting column 308 on the mounting bracket 302 fits tightly against the two ends of the windshield, thereby achieving lateral limitation of the windshield.

[0029] Subsequently, the limiting structure 4 of the device begins to function; the servo motor 401 drives the transmission belt mechanism 402, and with the assistance of the limiting slide rail 404, the slides 403 on both sides drive the limiting frames 405 on them to move closer to the center along with the transmission belt mechanism 402; when the second limiting post 406 on the limiting frame 405 contacts both sides of the windshield, it works in conjunction with the first limiting post 308 to achieve four-sided limiting of the windshield; through this precise limiting operation, the windshield is stably positioned at the center of the base frame 1 and the side frame 2, thereby achieving the centering and positioning effect of the windshield;

[0030] After centering and positioning, the windshield is in a stable and precise position. At this point, the adsorption mechanism can smoothly pick it up and move it to the designated position within the adhesive application equipment. Because the windshield has been precisely centered, the adhesive application equipment can accurately align with the predetermined adhesive application area on the windshield, thereby achieving precise adhesive application, ensuring the uniformity and integrity of the adhesive, and improving the overall quality and production efficiency of automotive windshields. This is the working principle of the centering device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
