Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board adsorption technology, specifically to a multi-nozzle synchronous quick-change flexible circuit board adsorption device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, and thinness, and are widely used in products such as mobile phones, laptops, PDAs, digital cameras, and LCMs. Before shipment, FPCs need to undergo electrical testing. During testing, an adsorption device picks up the FPC and moves it onto a fixture. The test is then performed by contacting probes. Because the sizes of different FPC models vary, multiple sets of suction plates are needed to accommodate them. During production, if the FPC model is changed, the corresponding suction plate must be replaced, requiring the disassembly of multiple sets of bolts and air pipes, which is inconvenient. After installation, the air pipes must be individually connected to the nozzles on the suction plate. Incorrect connection can cause deformation of the adsorption action, and in severe cases, adsorption failure, affecting the efficiency of the electrical test. Utility Model Content

A post and a second air passage are provided on the fixed base. A spring ball is embedded in the outer wall of the post, allowing both ends of the second air passage to penetrate the side wall and end face of the fixed base, respectively, forming a connecting hole and a second hole. When the movable base is inserted into the fixed base, the post inserts into the insertion hole, causing the spring ball to pass through the skirt and press against its side wall. The second hole and the first hole are sealed together, connecting the connecting hole to the suction nozzle. This allows for quick replacement of the suction plate and suction nozzles through the insertion and removal of the movable base, and avoids complicated air tube disassembly and assembly operations by utilizing the connection between the connecting hole and the suction nozzle.

[0026] like Figures 1 to 10 As shown, the multi-nozzle synchronous quick-change flexible circuit board adsorption device provided by this utility model includes: a fixed base 10, a movable base 20 detachably connected to the fixed base 10, a suction plate 30 connected to the end of the movable base 20 away from the fixed base 10, and a plurality of suction nozzles 40 disposed on the suction plate 30. The movable base 20 is provided with an insertion hole 21 and a plurality of first air passages 22. The opening of the insertion hole 21 is recessed to form a skirt 211. The skirt 211 is inclined away from the side wall of the fixed base 10 to form a conical snap-fit ​​surface. The number of first air passages 22 is greater than or equal to the number of suction nozzles 40. One end of the first air passage 22 penetrates the side wall of the movable base 20 and communicates with the suction nozzle 40 through a pipe (not shown in the figure). The other end penetrates the end face of the movable base 20 to form a first hole 23. The fixed base 10 is provided with an insertion post 11 and a second air passage 12. The outer wall of the insertion post 11 is embedded with a retractable spring. Ball 111 (the structure here is similar to the structure of the spring ball on the umbrella handle), there are three spring balls 111 and they are evenly distributed around the axis of the insert post 11. The radius of the insert post 11 is less than or equal to the radius of the hole 21 and less than the maximum distance from the axis of the insert post 11 to the spring balls 111. The second air channel 12 is set corresponding to the first air channel 22. One end of the second air channel 12 passes through the side wall of the fixed base 10 to form a connecting hole 13, and the other end passes through the end face of the fixed base 10 to form a second hole 14. The connecting hole 13 is used to connect the tube for supplying vacuum and / or air. When the movable base 20 is inserted into the fixed base 10, the insert post 11 with the spring balls 111 is inserted into the hole 21, so that the spring balls 111 pass through the skirt 211 and press against the skirt 211 away from the side wall of the fixed base 10. The second hole 14 is sealed and connected with the first hole 23, so that the connecting hole 13 is connected to the nozzle 40.

[0027] The advantage of this design is that it allows for quick replacement of the suction plate and nozzle by inserting and removing the movable base, and it avoids complicated air tube disassembly and assembly by connecting the connection hole to the nozzle.
