During the circuit printing process, it's unavoidable to flip the keyboard membrane; that is, after printing on one side, it's flipped over, and then the other side is printed. Currently, on printing production lines, this flipping is still done manually, resulting in low printing efficiency. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a keyboard membrane flipping device to solve the above-mentioned problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a keyboard membrane flipping device, including a frame and a flipping module and a flipping conveyor belt disposed on the frame. The flipping conveyor belt is used to transport the keyboard membrane located on the front side of the flipping module to the flipping module, and to transport the keyboard membrane located on the rear side of the flipping module away from the flipping module.

[0005] The flipping module includes a flipping drive shaft, a clamping assembly, and a lever. The flipping drive shaft is rotatably connected to the frame. The clamping assembly clamps the flipping drive shaft. Levers are provided on both the front and rear sides of the clamping assembly, and the lever located on the front side of the clamping assembly extends from back to front towards the lower side of the flipping conveyor belt.

[0006] Preferably, a plurality of clamping assemblies are evenly distributed along the length of the flip drive shaft, the flip propulsion conveyor belt is disposed between two adjacent clamping assemblies, a clearance gap is formed between two adjacent flip propulsion conveyor belts, and a lever located on the front side of the clamping assembly is located in the clearance gap to extend to the underside of the flip propulsion conveyor belt.

[0007] Optionally, the frame is provided with a front rotating rod and a rear rotating rod. The front rotating rod is located on the front side of the flipping module, and the rear rotating rod is located on the rear side of the flipping module. The front and rear sides of the flipping push conveyor belt are respectively connected to the front rotating rod and the rear rotating rod, and the flipping push conveyor belt is located on the lower side of the flipping drive shaft.

[0008] Specifically, the clamping assembly includes two clamping blocks arranged vertically, which are positioned opposite each other to clamp the flip drive shaft.

A lever located on the front side of the clamping assembly is located on the lower side of the forward-opening slot, and a lever located on the rear side of the clamping assembly is located on the upper side of the rearward-opening slot.

[0009] It is worth noting that the lever includes a connecting section and a curved section. The curved section is connected to the clamping assembly through the connecting section, and the curved section of the lever located on the front side of the clamping assembly bends downward.

[0010] Preferably, an input conveyor belt is provided on the front side of the flipping and pushing conveyor belt, and an output conveyor belt is provided on the rear side of the flipping and pushing conveyor belt.

[0011] The beneficial effects of this utility model are as follows: In the keyboard membrane flipping device, by setting the flipping module, after the keyboard membrane is conveyed to the front of the flipping module by the flipping push conveyor belt, the lever located on the front of the clamping component will be located below the keyboard membrane.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figure 1-3 As shown, a keyboard membrane flipping device includes a frame 1, a flipping module 2 disposed on the frame 1, and a flipping conveyor belt 3. The flipping conveyor belt 3 is used to transport the keyboard membrane located on the front side of the flipping module 2 to the flipping module 2, and to transport the keyboard membrane located on the rear side of the flipping module 2 away from the flipping module 2.

[0018] The flipping module 2 includes a flipping drive shaft 21, a clamping assembly 22, and a lever 23. The flipping drive shaft 21 is rotatably connected to the frame 1. The clamping assembly 22 clamps the flipping drive shaft 21. The clamping assembly 22 is provided with levers 23 on both the front and rear sides. The lever 23 located on the front side of the clamping assembly 22 extends from back to front towards the lower side of the flipping push conveyor belt 3, thereby ensuring that the end of the lever 23 located on the front side of the clamping assembly 22 is below the keyboard membrane on the flipping push conveyor belt 3.

[0019] In the keyboard membrane flipping device, by setting the flipping module 2, after the keyboard membrane is conveyed to the front of the flipping module 2 by the flipping push conveyor belt 3, the lever 23 located at the front of the clamping component 22 will be located below the keyboard membrane. By rotating the flipping drive shaft 21, the flipping drive shaft 21 drives the lever 23 to rotate through the clamping component 22. The lever 23 can then flip the keyboard membrane to the rear of the clamping component 22. At this time, the front and back of the keyboard membrane will be reversed, thus achieving the purpose of flipping the keyboard membrane.

[0020] Preferably, multiple clamping components 22 are evenly distributed along the length of the flip drive shaft 21. The flip propulsion conveyor belt 3 is positioned between two adjacent clamping components 22, and a clearance gap 31 is formed between two adjacent flip propulsion conveyor belts 3. A lever 23 located on the front side of the clamping component 22 is positioned within the clearance gap 31 to extend to the underside of the flip propulsion conveyor belt 3. This arrangement allows the clamping components 22 and the flip propulsion conveyor belt 3 to be staggered. When the flip drive shaft 21 drives the lever 23 to rotate via the clamping components 22, the lever 23 will not collide with the flip propulsion conveyor belt 3, ensuring stable operation of both the flip module 2 and the flip propulsion conveyor belt 3. With the lever 23 located on the front side of the clamping component 22 positioned within the clearance gap 31 to extend to the underside of the flip propulsion conveyor belt 3, when a keyboard membrane is input from the flip propulsion conveyor belt 3, the lever 23 is positioned below the keyboard membrane, facilitating the lever 23 to flip the keyboard membrane, thereby improving the flipping efficiency and ultimately increasing printing efficiency.

[0021] Optionally, the frame 1 is provided with a front rotating rod 11 and a rear rotating rod 12. The front rotating rod 11 is located on the front side of the flipping module 2, and the rear rotating rod 12 is located on the rear side of the flipping module 2. The front and rear sides of the flipping propulsion conveyor belt 3 are respectively connected to the front rotating rod 11 and the rear rotating rod 12 for transmission, and the flipping propulsion conveyor belt 3 is located below the flipping drive shaft 21. Both the front rotating rod 11 and the rear rotating rod 12 are rotatably connected to the frame 1, wherein a driving power source, such as a motor, drives the front rotating rod 11 or the rear rotating rod 12 to rotate, thereby driving the flipping propulsion conveyor belt 3 to work.

[0022] Specifically, the clamping assembly 22 includes two clamping blocks 221 arranged vertically, which are positioned opposite each other to clamp the flip drive shaft 21. A forward-opening slot 222 and a rearward-opening slot 222 are formed between the two clamping blocks 221. A lever 23 located at the front of the clamping assembly 22 is positioned below the forward-opening slot 222, and a lever 23 located at the rear of the clamping assembly 22 is positioned above the rearward-opening slot 222. In this embodiment, the two clamping blocks 221 are locked to the flip drive shaft 21 by bolts 223. After the keyboard membrane is embedded in the slot 222, the slot 222 acts as a limit, preventing the keyboard membrane from easily shifting when the flip module 2 flips the keyboard membrane.

[0023] It is worth noting that the lever 23 includes a connecting section 231 and a curved section 232. The curved section 232 is connected to the clamping assembly 22 via the connecting section 231. The curved section 232 of the lever 23, located on the front side of the clamping assembly 22, bends downward. By providing the curved section 232, the lever 23 located on the front side of the clamping assembly 22 can have a section that slopes upward from front to back, thereby serving as a guide and allowing the keyboard membrane to enter the support range of the lever 23.

[0024] Preferably, an input conveyor belt 4 is provided in front of the flip-propellant conveyor belt 3, and an output conveyor belt 5 is provided in rear of the flip-propellant conveyor belt 3. The drive sources of the flip-propellant conveyor belt 3, the input conveyor belt 4, and the output conveyor belt 5 are all independent, thereby ensuring that the three can operate independently. In use, the input conveyor belt 4 transports the keyboard membrane from the previous station to the flip-propellant conveyor belt 3, the flip-propellant conveyor belt 3 transports the keyboard membrane to the output conveyor belt 5, and the output conveyor belt 5 transports the keyboard membrane to the next station.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
