Description
Technical Field
[0001] The utility model relates to the technical field of semi-automatic assembly of vehicle-mounted HUD, in particular to a semi-automatic assembly device for vehicle-mounted HUD. Background Art
[0002] The in-vehicle HUD, or head-up display, is a high-tech device that projects driving information directly onto the windshield in front of the driver. During HUD assembly, a conveyor belt is typically used to automatically load the circuit boards into a welding machine for welding and assembly to ensure a stable connection between the internal electronic components and the circuit boards.
[0003] After searching, the Chinese patent "Circuit Board Loading Device" authorization announcement number "CN218183857U" realizes the adsorption and transportation of the circuit board to the top of the first conveyor belt through the first electric push rod and the suction cup, and then through the second electric telescopic rod and the push plate, the push plate is moved down to push the suction cup to adsorb the circuit board, so that the circuit board falls onto the first conveyor belt, and then the circuit board is welded by the welding machine, thereby achieving the effect of loading the circuit board.
[0004] In the above application, since the circuit board is relatively thin, in order to ensure that the suction cup stably adsorbs the circuit board, the suction cup will increase the downward pressure on the circuit board, which may easily cause damage to the surface of the circuit board.
[0005] Therefore, a semi-automatic assembly device for vehicle-mounted HUD is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the present invention is to provide a semi-automatic assembly device for a vehicle-mounted HUD in order to solve the above-mentioned problem, thereby improving the problem that the suction cup will increase the downward pressure on the circuit board, which may easily cause damage to the surface of the circuit board.
[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a semi-automatic assembly device for vehicle-mounted HUD, comprising: a welding machine, a conveyor frame is provided on one side of the welding machine, a driving mechanism is provided on the top of the conveyor frame, and a pressure balance component is provided at the lower end of the surface of the driving mechanism; wherein, the pressure balance component includes a buffer assembly and a feed barrel, one end of the feed barrel is connected to a through pipe, the inner wall of the feed barrel is slidably connected to a slide rod, two display blocks are fixedly connected to the surface of the slide rod, one end of the feed barrel is fixedly connected to an observation ring, and a plurality of suction cups are provided at the bottom of the buffer assembly.
[0008] Preferably, the buffer assembly includes a movable frame disposed at the bottom of the driving mechanism, the inner wall of the movable frame being slidably connected to a movable rack, the top of the suction cup being fixedly connected to the bottom of the movable rack, the interior of the movable frame being filled with gas, one end of the feed barrel being fixedly connected to the upper surface of the movable frame, and one end of the through-tube being in communication with the upper surface of the movable frame. The gas filled in the movable frame and the movable rack allow the gas in the movable frame to be pushed into the feed barrel through the through-tube. Excessive gas in the feed barrel pushes the slide bar and the display block to move through the observation ring, stopping the downward pressure of the suction cup, thereby achieving balanced pressure on the top of the circuit board and preventing damage to the circuit board caused by excessive downward pressure of the suction cup.
[0009] Preferably, the top end of the suction cup is connected to a main pipe, the upper surface end of the main pipe is connected to a piston cylinder, the surface of the piston cylinder is fixedly connected to the upper surface end of the movable frame, the inner wall of the piston cylinder is slidably connected to the piston frame, the upper surface end of the movable frame is fixedly connected to a first electric push rod, and the telescopic end of the first electric push rod is fixedly connected to one side of the piston frame. As the piston frame moves within the piston cylinder, suction is generated within the piston cylinder, causing air in the four suction cups to be sucked into the piston cylinder through the main pipe, thereby causing the suction cups to vacuum-adhere to the circuit board, ensuring stable suction of the circuit board by the suction cups.
[0010] Preferably, the upper surface end of the manifold is connected to a first one-way valve for preventing gas in the manifold from flowing into the piston cylinder. The upper surface end of the piston cylinder is connected to a one-way air outlet pipe. The one-way air outlet pipe enables the piston frame to push gas out of the piston cylinder, thereby preventing excessive gas from accumulating in the piston cylinder and ensuring that the piston cylinder effectively absorbs gas in the suction cup.
[0011] Preferably, a first spring is fixedly connected to the inner top wall of the movable frame, and a bottom end of the first spring is fixedly connected to the top end of the movable frame.
[0012] Preferably, a second spring is fixedly connected to one end of the inner wall of the feed barrel, and the other end of the second spring is fixedly connected to one end of the slide rod. Through the first and second springs, the second spring pushes the slide rod toward the through pipe, and the first spring pushes the movable frame downward, thereby causing some of the gas in the feed barrel to flow back into the movable frame.
[0013] Preferably, the surface of the main pipe is connected to an air inlet pipe, and one end of the surface of the air inlet pipe is trumpet-shaped. The trumpet-shaped air inlet pipe at one end of the surface facilitates the guidance of a large amount of external air through the air inlet pipe and the main pipe to flow into the suction cup, thereby facilitating the release of the suction cup from the circuit board.
[0014] Preferably, a sealing frame is slidably connected to the upper end of the surface of the movable frame, the surface of the sealing frame being in close contact with the inner wall of the intake pipe, and a third spring is fixedly connected to the sealing frame on the opposite side of the movable frame. The third spring pushes the sealing frame to move in close contact with the inside of the intake pipe, thereby sealing the intake pipe.
[0015] The beneficial effects of the utility model are:
[0016] The gas filled in the movable frame, the movable rack, the feed cylinder, the slide rod and the observation ring achieve balanced pressure on the top of the circuit board, preventing damage to the circuit board caused by excessive downward pressure of the suction cup. Compared with the existing suction cup that excessively presses down to adsorb the circuit board, this method uses balanced pressure to adsorb the circuit board, ensuring the integrity of the circuit board during loading.
[0017] Through the electric push rod, piston rack and piston cylinder, the air in the four suction cups is adsorbed into the piston cylinder through the main pipe, and then the suction cups are vacuum-adsorbed on the circuit board, ensuring the stability of the suction cups in adsorbing the circuit board.

The telescopic end of the second electric push rod moves downward, driving the movable frame 411, the movable frame 412 and the suction cup 43 to move downward, so that the suction cup 43 is pressed down on the top of the circuit board. The telescopic end of the second electric push rod continues to move downward, driving the movable frame 411 to move downward, so that the movable frame 412 moves upward in the movable frame 411 and pushes the gas in the movable frame 411 to flow into the feed barrel 46 through the through pipe 45. The gas in the feed barrel 46 is sufficient to push the slide rod 47 to move in the feed barrel 46. When the slide rod 47 and the display block 42 move through the observation ring 48, the second electric push rod is manually closed. , so that the suction cup 43 is pressed on the top of the circuit board and adsorbs it. At this time, the servo motor is automatically turned on, and the output shaft of the servo motor rotates to drive the screw to rotate. The rotation of the screw drives the slider, the second electric push rod, the pressure-balancing component 4 and the adsorbed circuit board to move above the conveyor belt. At this time, the adsorption of the circuit board is released, and the circuit board enters the welding machine 1 through the conveyor belt. The machine inside the welding machine 1 automatically welds the circuit board. After the circuit board is welded, it is transported to the next assembly link. The circuit board welding process is a link in the entire process of semi-automatic assembly of vehicle-mounted HUD. The entire process of semi-automatic assembly of vehicle-mounted HUD is an existing well-known technology and will not be described in detail here.
[0027] like Figure 4 As shown, the top of the suction cup 43 is connected to the main pipe 44, the upper surface of the main pipe 44 is connected to the piston cylinder 49, the surface of the piston cylinder 49 is fixedly connected to the upper surface of the movable frame 412, the inner wall of the piston cylinder 49 is slidably connected to the piston frame 491, the upper surface of the movable frame 412 is fixedly connected to the first electric push rod 492, the telescopic end of the first electric push rod 492 is fixedly connected to one side of the piston frame 491, the upper surface of the main pipe 44 is connected to the first one-way valve 493, the first A one-way valve 493 is used to block the gas in the main pipe 44 from flowing into the piston cylinder 49. The upper surface of the piston cylinder 49 is connected to a one-way air outlet pipe 494, and the surface of the main pipe 44 is connected to an air inlet pipe 495. One end of the surface of the air inlet pipe 495 is trumpet-shaped. The upper surface of the movable frame 412 is slidably connected to a sealing frame 496. The surface of the sealing frame 496 is tightly attached to the inner wall of the air inlet pipe 495. The sealing frame 496 and the opposite side of the movable frame 412 are fixedly connected with a third spring 497.

One end of the feed cylinder 46 is fixed to one side of the fixed block. The surface of the through pipe 45 is located on the inner wall of the fixed block. The movable frame 412 includes a connecting plate and a movable rod. The top of the connecting plate is fixed to the bottom end of the movable rod. The surface of the movable rod is slidably connected to the inner wall of the movable cylinder. The movable rod, sliding rod 47, piston frame 491 and sealing frame 496 are all rubber components.
[0030] The one-way air outlet pipe 494 includes a second one-way valve and an air outlet pipe. The bottom end of the air outlet pipe is connected to the upper surface of the piston cylinder 49. The second one-way valve is used to prevent external gas from entering the piston cylinder 49 through the air outlet pipe. A retaining ring is fixedly connected to the inner wall of the piston cylinder 49 to prevent one end of the piston frame 491 from moving below the air inlet of the one-way air outlet pipe 494.

[0035] It should be noted that the first electric push rod 492, conveyor belt, welding machine 1, first one-way valve 493, second one-way valve, second electric push rod and servo motor in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs.
