Description

Technical Field

[0001] The utility model relates to the technical field of film key installation, in particular to a film key alignment parts installation device. Background Art

[0002] Membrane keypad alignment parts installation refers to the process of accurately installing membrane keys with graphics, characters and other logos on designated locations (such as circuit boards, panels, casings, etc.) during the manufacturing process of electronic equipment, instruments, meters, household appliances and other products.

[0003] Since membrane keys have adhesive on the back, they need to be supported first during installation. After alignment, the membrane keys are pressed to fit a portion of the workpiece before the supporting components are withdrawn. The withdrawal of supporting components is usually done manually, which is the lowest cost. Some are driven by power sources, which is convenient but difficult to promote due to its high cost.

[0004] Therefore, a membrane key alignment parts mounting device has been developed which can automatically withdraw the membrane key support component when the membrane key is pressed and pasted, thereby improving the quality and efficiency of the membrane key mounting. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned background technology, the technical problem is to provide a membrane key alignment parts mounting device which can automatically withdraw the membrane key support component when pressing and pasting the membrane key, thereby improving the quality and efficiency of membrane key mounting.

[0006] The technical solution of the utility model is: a membrane keypad alignment parts mounting device, comprising a workbench, a support arm, a slide bar, an alignment frame, a positioning strip, a clamping mechanism and a synchronization mechanism, the left and right sides of the workbench are connected to the support arms, the support arms are slidably connected to the slide bars, the sides of the slide bars close to each other are connected to the alignment frame, the workbench is connected to the positioning strip, the top of the workbench is provided with a clamping mechanism, and the clamping mechanism is provided with a synchronization mechanism.

[0007] As a further preferred solution, the bottom of the workbench is a U-shaped structure.

[0008] As a further preferred solution, a support plate is provided on each alignment frame.

[0009] As a further preferred solution, the positioning bar is an L-shaped structure.

[0010] As a further preferred solution, the clamping mechanism includes an electric push rod, a connecting frame, a contact frame and a first spring. The electric push rod is connected to the top of the workbench, the telescopic end of the electric push rod is connected to the connecting frame, the contact frame is slidably connected to the connecting frame, and the left and right parts of the slot frame are connected to the connecting frame with a first spring. The telescopic end of the electric push rod controls the movement of the connecting frame downward, and the movement of the connecting frame drives the contact frame to move forward to press the membrane button, and the membrane button is pasted on the workpiece.

[0011] As a further preferred embodiment, the synchronization mechanism includes a contact strip, a wedge block, a second spring, a vacuum air pump, a sliding frame and a suction cup. The left and right sides of the connecting frame are connected to contact strips, the top of the sliding rod is connected to a wedge block, the contact strips are squeezed and matched with adjacent wedge blocks, the sliding rod is connected to a second spring between adjacent support arms, the front side of the upper part of the workbench is connected to a vacuum air pump, the left and right parts of the workbench are slidably connected to the sliding frame, a conduit is provided between the top of the sliding frame and the vacuum air pump, the sliding frame is connected to adjacent contact strips, the bottom of the sliding frame is connected to a suction cup, and the connection The frame moves downward, driving the contact strip to move downward. The contact strip moves downward to squeeze the wedge block, so that the wedge block controls the sliding rods to move away from each other and stretch the second spring when the connecting frame moves downward. While the contact strip moves downward, it also drives the sliding frame to move downward. The sliding frame moves downward and drives the suction cup to contact the membrane button. At this time, the vacuum air pump starts to suck out the air inside the sliding frame, so that the suction cup generates negative pressure, which adsorbs the membrane button and stabilizes the membrane button. When the membrane button is pasted, the vacuum air pump releases the negative pressure state of the suction cup, so that the suction cup can be separated from the membrane button normally.

[0012] The utility model has the following advantages: the utility model drives the contact strip to move downward by the downward movement of the connecting frame, and the contact strip moves downward to squeeze the wedge block, so that the wedge block controls the operation of the slide bars to move away from each other when the connecting frame moves downward, and can automatically withdraw the membrane key support component when the membrane key is pressed to be pasted, thereby improving the quality and efficiency of membrane key installation.
