Description

Technical Field

[0001] The utility model relates to the field of glass detection, in particular to a curved glass clamping device. Background Art

[0002] In the glass inspection operation, special clamping equipment is required to clamp and fix the glass. The structure of the clamping equipment can refer to the utility model patent with application number CN202023189773.9, which is named a universal HUD optical inspection device. Due to the characteristics of the curved glass structure, the positioning device of the commonly used flat glass is difficult to be applied to the clamping and positioning operation of the curved glass. At present, most of the glass equipment manufacturers on the market use special fixed fixtures to clamp and position the curved glass.

[0003] Since the production of special fixed fixtures for curved glass is similar to product mold making, each type of curved glass needs to be customized with corresponding fixtures, which leads to the following defects:

[0004] (1) Poor adaptability: Fixed tooling is usually designed for specific products or processes, which makes it difficult to adapt to product changes or process changes. Once the product or process changes, the tooling may need to be redesigned or adjusted, which increases production preparation time and cost.

[0005] (2) Limited flexibility: The structure and position of fixed tooling are usually fixed, which will limit the operator's working space. This limitation may affect the operator's work efficiency and comfort, and may even increase the risk of operating errors.

[0006] (3) High maintenance cost: Once fixed tooling fails or wears out, it requires special repair and replacement, which may require additional equipment, time and personnel, increasing maintenance costs and downtime.

[0007] (4) Inconvenient storage and transportation: Fixed tooling is usually large in size and difficult to store and transport. When the production line layout needs to be moved or adjusted, fixed tooling may become a problem.

[0008] (5) Low standardization: Different fixed tools may adopt different design and manufacturing standards, which increases management difficulty and cost. At the same time, the lack of standardization may also lead to compatibility issues between different tools.

[0009] (6) High investment risk: Since fixed tools are usually designed for specific products or processes, if the product or market changes, these tools may become no longer applicable. This may lead to wasted investment and the risk of idle assets.

[0010] (7) Models that cannot adapt to new composite production lines: In order to improve equipment utilization efficiency, site space utilization efficiency, and reduce comprehensive production costs, current manufacturers are increasingly inclined to a production model in which one production line is compatible with multiple different models of products. In this model, fixed tooling needs to be frequently replaced according to the production plan of the production line. Each mold change requires operators to recalibrate and test, which is time-consuming and labor-intensive, increases labor costs, and inevitably compresses the effective production time of the production line and reduces production efficiency.
