Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for a glass cover plate. Background Art

[0002] The clamping device, also known as a fixture or clamping device, is a device used to prevent the workpiece from displacement or vibration during the processing. Under the premise of not changing the position of the workpiece during the clamping process, the clamping force must be large enough to ensure that the workpiece does not displace or vibrate during the processing, and does not crush the workpiece surface or cause deformation, especially workpieces that are easy to crack or break.

[0003] The glass cover is the back cover located at the rear end of the mobile phone, which plays a role in protecting the base of the mobile phone and meeting the requirements of the outer tube. Then, there are certain requirements for the strength of the glass cover, so as to reduce the probability of breakage caused by the touch of foreign objects. However, as a workpiece made of glass, it will still break, shatter or crack when touched by foreign objects, which will directly affect the performance of the glass cover. Of course, in the production process of the glass cover, the clamping work of the clamping device will also make the glass cover bear the clamping force. In order to prevent the glass cover from being damaged during production, the structure of the glass cover production device (including the clamping device) naturally needs to be carefully designed.

[0004] China Patent Authorization Announcement No.: CN215248128U, authorization announcement date December 21, 2021, discloses a clamping device for a glass cover plate, including a base plate, a support column for supporting the base plate is fixedly installed on the bottom surface of the base plate, a movable plate connected to an external control device is arranged above the base plate, and a mounting plate is fixedly installed on the side of the movable plate close to the base plate using a connecting rod, a grab block is arranged below the mounting plate, a hinge shaft for the grab block to move is movably installed on the grab block, and a movable movable pressure plate is arranged on the upper surface of the base plate, and a bearing column for bearing the glass cover plate is installed through the movable pressure plate. The shortcoming of this technical solution is that when the glass cover plate is clamped, the glass cover plate is first placed on the bearing column, limited by the bearing column, and then the grab block on the movable plate is directly controlled to grab the two ends of the glass cover plate, thereby controlling the upward movement of the glass cover plate. However, the glass cover here only moves under the limiting effect of the grab blocks at the two symmetrical ends, and no other operation design is made at other positions. Therefore, the limiting effect of the glass cover is not stable, which may cause the glass cover to detach from the unrestricted position during the upward movement, thereby causing damage to the glass cover.

[0005] In summary, a design capable of stably limiting the position of the glass cover can be provided so that the glass cover can stably move up and down. Utility Model Content
