Description

Technical Field

[0001] The utility model relates to the technical field of glass assembly, in particular to a glass pressing tool. Background Art

[0002] The existing B-pillar glass and substrate pressing and assembling scheme usually includes the following steps: the substrate is grasped by a robot and a suction cup and placed on the lower mold of the pressing tooling, and the pressing lower mold is limited by the main and auxiliary positioning columns of the substrate and the doghouse (a buckle-like protrusion on the back of the car interior column). Similarly, the glass is grasped by the robot suction cup and placed on the pressing upper mold. There are two limit columns in the lower mold of the pressing tooling, and the limit columns are adjusted to control the downward stroke of the pressing tooling and the pressing pressure. At the same time, the theoretical design requires that the glass surface and the pressing upper mold fitting surface are close to completely fitting. Although the existing pressing upper mold surface is a contoured design, the actual glass surface state fluctuates, making it impossible for the glass and the pressing upper mold surface to achieve theoretical complete fitting, resulting in uneven force during the assembly of the glass and the substrate, causing scratches on the glass surface. Utility Model Content

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] In the prior art, the upper mold surface of the pressing tool is a contoured design, but the actual glass surface state fluctuates, which easily leads to the failure of the glass and the mold to achieve theoretical complete fit during the pressing of the upper and lower molds, resulting in uneven force at each point during the assembly of the glass and the substrate. Therefore, during the production process, some areas of the glass and the substrate will not fit. In addition, the size of the glass and the substrate fluctuates. The current limiting method of the pressing tool also has production tolerances. Therefore, if the linear contour size of the two after pressing cannot be monitored in real time during the pressing process, batch size defects are likely to occur, and products with defective dimensions cannot be repaired after curing, which ultimately leads to the scrapping of a large number of products. At the same time, it is impossible to check for overpressure or insufficient pressure during the pressing process; and the height needs to be adjusted by disassembling and grinding the limit column or adding gaskets to reinstall it, which is time-consuming and labor-intensive.

[0024] Therefore, based on the above-mentioned technical problems, the present application provides a glass pressing tool, which adopts a plurality of groups of non-collinear limit columns whose pressing ends form abutting surfaces to abut against the glass, and optimizes the original surface contact method of the imitation part to a point contact method, which can more effectively fit with the glass surface and avoid the problem of scratches on the glass surface caused by uneven force during the assembly of the glass and the substrate.

[0025] The glass pressing tool provided by this application is not only applicable to the production of automobile B-pillar trims, but also applicable to the application scenarios of glass and glass products, specifically:

[0026] Please refer to Figure 1 as well as Figure 2 A glass pressing tool comprises a pressing upper mold 1, a pressing lower mold 2 and a servo mechanism 3; the pressing upper mold 1 is arranged opposite to the pressing lower mold 2; the servo mechanism 3 is connected to the pressing upper mold 1, driving the pressing upper mold 1 to move in a direction away from or close to the pressing lower mold 2; at least three groups of non-collinear limiting columns 11 are arranged on the side of the pressing upper mold 1 facing the pressing lower mold 2; the end of the limiting column 11 facing the pressing lower mold 2 is a pressing end, and the pressing ends of all the limiting columns 11 form a contact surface for contacting with the glass. By arranging multiple groups of non-collinear limiting columns 11 on the surface of the pressing upper mold 1, the contact surface formed by the pressing ends of the limiting columns 11 is contacted with the glass, and the surface contact between the original upper mold surface and the glass surface is optimized to a point contact mode, which can be more effectively bonded to the glass surface, and avoid the problem of scratches on the glass surface caused by uneven force during the assembly of the glass and the substrate.

[0027] In an alternative embodiment, the distance between the pressing end of the limiting post 11 and the upper pressing die 1 is adjustable. That is, according to the actual flatness of the glass surface to be pressed, the height of the limiting posts 11 at different positions can be adjusted so that each limiting post 11 can fit the glass surface, and thus the pressing end of the limiting post 11 forms a contact surface that can effectively fit the glass.

[0028] In an alternative embodiment, the upper pressing die 1 is provided with a fixing post 12 and a locking member 13; the limiting post 11 is embedded in the fixing post 12; the locking member 13 is arranged between the limiting post 11 and the fixing post 12. By embedding the limiting post 11 in the fixing post 12 and locking the position of the limiting post 11 through the locking member 13, the effect of adjusting the distance between the pressing end of the limiting post 11 and the upper pressing die 1 is achieved.

[0029] In an alternative embodiment, a protective rubber sleeve 14 is sleeved on the pressing end of the limiting post 11. By sleeving the protective rubber sleeve 14 on the pressing end of the limiting post 11, the pressing end of the limiting post 11 can be prevented from scratching the glass surface, playing a protective role for the glass surface.

[0030] In an alternative embodiment, a pressure detection device 4 is arranged at one end of the servo mechanism 3 connected to the upper pressing die 1. By adding the pressure detection device 4 to the servo mechanism 3, the pressure during the pressing process can be detected in real time, and the pressing stroke of the upper pressing die 1 during the pressing process can be controlled by setting the pressure value, greatly shortening the pressure debugging time and improving the production efficiency of the workshop.

[0031] In an alternative embodiment, both the upper pressing die 1 and the lower pressing die 2 are provided with a dimension detection device 5 for detecting the distance of the glass side profile. By arranging the dimension detection device 5 on both the upper pressing die 1 and the lower pressing die 2, the line profile of the product can be automatically identified through the dimension detection device 5, ensuring the dimension of the product line profile and avoiding the problem of poor dimensions, thereby solving the problem of poor dimensions during the product pressing process.

[0032] In an alternative embodiment, the dimension detection device 5 on the upper pressing die 1 and the dimension detection device 5 on the lower pressing die 2 are arranged in a staggered manner for detecting the distances of different glass side profiles. By arranging the dimension detection device 5 in a staggered manner, interference between the dimension detection devices 5 during the pressing process can be avoided, and at the same time, the distances of different glass side profiles can be detected.

[0033] In an alternative embodiment, both the upper pressing die 1 and the lower pressing die 2 are provided with at least two groups of dimension detection devices 5, and the positions of the glass side profiles corresponding to different dimension detection devices 5 are different. By arranging multiple groups of dimension detection devices 5, the positions of multiple glass side profiles can be detected, ensuring the accuracy of the glass dimensions.

[0034] In an alternative embodiment, the lower pressing die 2 includes a dimension detection device 5 disposed on its first side and a dimension detection device 5 disposed on its second side; the first side of the lower pressing die 2 is perpendicular to its second side. By disposing the dimension detection devices 5 on both perpendicular sides of the lower pressing die 2, the detection of the side and top edge contour positions of the glass is realized.

[0035] In an alternative embodiment, a fixing mechanism 6 is further included; the fixing mechanism 6 is slidably connected to the upper pressing die 1 to move the upper pressing die 1 away from or closer to the lower pressing die 2. By restricting the movement of the upper pressing die 1 by the fixing mechanism 6, when the upper pressing die 1 is driven by the servo mechanism 3 to move, the stability of the movement process of the upper pressing die 1 can be improved and the shaking can be reduced.

[0036] The following embodiments are preferred solutions of the above embodiments.

[0037] Please refer to Figure 1 and Figure 2 , a glass pressing tooling, including an upper pressing die 1, a lower pressing die 2, a servo mechanism 3 and a fixing mechanism 6; the upper pressing die 1 and the lower pressing die 2 are oppositely arranged; the servo mechanism 3 is connected to the upper pressing die 1 to drive the upper pressing die 1 to move away from or closer to the lower pressing die 2; the fixing mechanism 6 is slidably connected to the upper pressing die 1 to move the upper pressing die 1 away from or closer to the lower pressing die 2. As shown in Figure 1 , both ends of the upper pressing die 1 are connected to the slide rails of the fixing mechanism 6 to move the upper pressing die 1 along the direction defined by the slide rails. Among them, a pressure detection device 4 is arranged at one end of the servo mechanism 3 connected to the upper pressing die 1; the pressure detection device 4 can be a pressure sensor, and the pressing stroke of the tooling is identified and adjusted through the pressure sensor.

[0038] Please refer to Figure 2 , at least three groups of non-collinear limit posts 11 are arranged on the side of the upper pressing die 1 facing the lower pressing die 2; one end of the limit post 11 facing the lower pressing die 2 is a pressing end, and the pressing ends of all the limit posts 11 form a contact surface for contacting the glass; the number of the limit posts 11 and the size of the contact surface can be adjusted according to the actual situation. For example, if the glass area is large, the number of the limit posts 11 can be increased and the diameter of the limit posts 11 can be increased; at the same time, the distance between the pressing end of the limit post 11 and the upper pressing die 1 can be adjusted to adapt to the height fluctuation of the glass surface. As shown in Figure 2 , a total of 12 groups of limit posts 11 are arranged on the upper pressing die 1 in this embodiment; the specific positions of the 12 groups of limit posts 11 can be set according to the actual glass contour to form a contact surface that effectively fits the glass.

[0039] Among them, in an optional embodiment, the distance between the pressing end of the limiting post 11 and the upper pressing die 1 is adjusted by the fixing post 12 and the locking member 13; the limiting post 11 is embedded in the fixing post 12; the locking member 13 is arranged between the limiting post 11 and the fixing post 12. For example, in other embodiments, a glass bead can be used as the locking member 13, and a limiting hole is arranged on the side wall of the limiting post 11, and the height of the limiting post 11 is adjusted by the glass bead and the limiting hole. Or the limiting post 11 is threadedly connected to the fixing post 12, and the height is adjusted by rotating the limiting post 11. At the same time, in order to prevent the pressing end of the limiting post 11 from scratching the glass surface, a protective rubber sleeve 14 is sleeved on the pressing end of the limiting post 11.

[0040] Please refer to Figure 3 , both the upper pressing die 1 and the lower pressing die 2 are provided with a dimension detection device 5 for detecting the distance of the side contour of the glass, which is used to detect the distance of the side contour of the glass; the dimension detection device 5 can adopt a laser sensor or a CCD (charge-coupled device camera, a camera using a charge-coupled device in a line array or a surface array as a detector) photographing device to automatically identify the line contour of each production product; among them, the number of the dimension detection devices 5 can be set according to the actual size of the glass to be detected and the contour characteristics, and the positions of the side contours of the glass corresponding to different dimension detection devices 5 are different; for example, the lower pressing die 2 includes a dimension detection device 5 arranged on its first side and a dimension detection device 5 arranged on its second side; the first side of the lower pressing die 2 is perpendicular to its second side; at the same time, the dimension detection device 5 on the upper pressing die 1 and the dimension detection device 5 on the lower pressing die 2 are arranged in a staggered manner, which is used to detect the distances of different side contours of the glass and avoid interference between the upper and lower dimension detection devices 5 during pressing.

[0041] As Figure 3 shown, two groups of dimension detection devices 5 are arranged on the outer side of the upper pressing die 1, and two groups of dimension detection devices 5 are also arranged on the corresponding other side of the lower pressing die 2. At the same time, a group of dimension detection devices 5 are also arranged at the small end position of the lower pressing die 2; during the mold closing and pressing process, the distances of three sides of the glass line contour are identified by the five groups of dimension detection devices 5, and the corresponding distance values are set according to the product fluctuation tolerance requirements for control, so as to realize 100% monitoring and inspection of each defective size product and synchronous alarm.

[0042] The specific pressing process of the above glass pressing tooling is as follows:

[0043] Loosen the locking member 13 according to the actual profile of the glass to adjust the height of the limit post 11, and then lock the limit post 11 through the locking member 13. After the glass substrate is positioned in the pressing equipment, the servo mechanism 3 first quickly descends to the pre-pressing position, and then slowly presses the glass substrate into shape after reaching the pre-pressing position. During this process, the pressure detection device 4 detects the pressure value. When the set pressure value is reached, the servo mechanism 3 will stop pressing down; at the same time, the real-time pressure value can also be automatically fetched and recognized by the equipment. When the forming and holding pressure time is reached, control the servo mechanism 3 to slowly rise to ensure that the semi-finished product after pressing into shape does not rebound or shake. At the same time, during the mold closing and pressing process, the edge distance of the glass line contour is detected by the detection device recognition sensor, and an alarm is synchronized when the size is abnormal.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
