Description
Technical Field
[0001] This invention belongs to the field of pressing robot technology, and in particular relates to a device for rapid pressing of products. Background Technology
[0002] The electric bicycle instrument panel is a core component that integrates riding data display functions such as speed, battery level, and mileage, as well as fault alarm functions. It consists of components such as a lower shell assembly and an upper shell assembly. The upper shell assembly includes an upper housing and a display screen, while the lower shell assembly includes a lower housing and a circuit board. The display screen is electrically connected to the circuit board in the lower shell via a wiring harness. Moreover, the electric bicycle instrument panel is a key device for realizing human-computer interaction and ensuring riding safety. To ensure the sealing of the connection between the upper and lower shells and the assembly efficiency, existing electric bicycle instruments often use a snap-fit connection and a pressing process during the assembly and processing of the electric bicycle instrument panel.
[0003] Currently, the pressing and assembly process of electric bicycle instrument panels is mostly done manually. First, the staff takes out the lower shell component and the upper shell component to be pressed and assembled. Then, the upper shell component is aligned with the lower shell component. Finally, the upper shell component and the lower shell component are pressed together manually. The whole pressing and assembly process is quite inconvenient, which not only affects the efficiency and convenience of pressing and assembling electric bicycle instrument panels, but also increases the labor intensity of the staff.
[0004] Furthermore, during the manual pressing and assembly of electric bicycle instrument panels, insufficient pressing force can easily occur, resulting in incomplete pressure assembly of the upper and lower shell components, and potential warping in some areas, which in turn affects the quality of the pressing and assembly of the electric bicycle instrument panels.

[0018] Compared with existing technologies, the advantages of a device for rapid product pressing are:
[0019] 1. Using a six-axis industrial robot, an upper shell assembly positioning mechanism, and positioning components, when the electric bicycle instrument panel needs to be pressed and assembled, firstly, a matching positioning slot is selected according to the size of the electric bicycle instrument panel. Then, industrial robots at other workstations separately transfer the lower shell assembly from the lower shell assembly conveyor line to the positioning slot, and the lower shell assembly is stably placed in the groove of the positioning slot. Next, the PLC control cabinet controls the six-axis industrial robot to move the upper shell assembly positioning mechanism above the upper shell assembly conveyor line. Then, the upper shell assembly positioning mechanism, in conjunction with the positioning components, uses stable negative pressure to pick up the upper shell assembly and aligns it directly above the lower shell assembly to be pressed and assembled. This is paused for a period of time, during which the operator connects the wiring harness of the upper shell assembly to the lower shell assembly. After this pause, the PLC control cabinet again controls the six-axis industrial robot to move the upper shell assembly positioning mechanism downwards, so that... Within the upper shell assembly positioning mechanism, the upper shell assembly can be stably and reliably pressed and assembled with the lower shell assembly. In the initial pressing stage, due to the reaction force of the lower shell assembly, the upper shell assembly will slide upward within the positioning mechanism. At this time, the pressing plate and the arc-shaped pressing block are in close contact with the upper surface of the upper shell assembly and apply a uniform pressing force to the upper shell assembly, ensuring that the pressing force on the upper shell assembly is uniform. At the same time, due to the reverse resistance of the pressing plate and the arc-shaped pressing block, it can be ensured that the downward pressing degree of the upper shell assembly is in place, and the upper shell assembly and lower shell assembly are accurately engaged, without local warping due to insufficient pressure. This design enables the pressing and assembly of electric bicycle instruments to be completed automatically, with uniform pressing force distribution, proper pressing and assembly, and no local warping defects. It not only improves the convenience, quality, and efficiency of electric bicycle instrument pressing and assembly, but also reduces the labor intensity of workers.
[0020] 2. Through the set lower shell component positioning mechanism and the dual-purpose air pump for blowing and sucking, while the positioning component picks up the upper shell component under negative pressure, the PLC control cabinet controls the lower shell component positioning mechanism to work. The lower shell component positioning mechanism can position and limit the lower shell component to be pressed and assembled, ensuring the stability of the lower shell component and the upper shell component during pressing and assembly, thereby ensuring the accuracy of pressing and assembly. After the upper shell component and the lower shell component are pressed and assembled, the PLC control cabinet then controls the release of the lower shell component positioning mechanism from the lower shell component limit, and uses the upper shell component positioning mechanism to transfer the pressed and assembled electric bicycle instrument. This mechanism can effectively improve the stability of the electric bicycle instrument during pressing and assembly, and enable the device to have the function of transferring electric bicycle instruments, improving the convenience of the device.
[0021] 3. Through the installation of a dual-purpose air pump, a semiconductor cooler, and a third air pipe, when the dual-purpose air pump starts blowing, the PLC control cabinet also controls the semiconductor cooler to work. The semiconductor cooler lowers the temperature of the metal mesh block. The air blown by the dual-purpose air pump is cooled as it passes through the low-temperature metal mesh block. The low-temperature air is then filtered and purified through a sponge block and a filter plate. The clean low-temperature air enters the second air pipe, and then some of the air is injected into the PLC control cabinet through the third air pipe, accelerating the airflow inside the PLC control cabinet. At the same time, the low-temperature air accelerates the heat exchange inside the PLC control cabinet, improving the heat dissipation effect of the PLC control cabinet. Finally, the cooled air is ejected through a one-way jet nozzle. This mechanism enables the device to have the function of automatic and efficient cooling of the PLC control cabinet, improving the reliability of the device's automated control, while ensuring the effect of the electric bicycle instrument pressing and assembly.

[0036] The CCD vision camera 710, the ranging sensor 711, and the pressure sensor 85 are all electrically connected to the input terminal of the PLC control cabinet 2 via wires. The six-axis industrial robot 1, the normally closed solenoid valve 57, the dual-purpose air pump 94, the semiconductor cooler 99, and the electric push rod 10 are all electrically connected to the output terminal of the PLC control cabinet 2 via wires. The above-mentioned electrical components and connections are all existing technologies and will not be described in detail here.
[0037] The operating principle of this invention is described as follows: When the electric bicycle instrument needs to be press-fitted and assembled, firstly, a matching positioning slot plate 53 is selected according to the size of the electric bicycle instrument, and the positioning slot plate 53 is placed on top of the hollow block 52. Then, a control program is preset in the PLC control cabinet 2 to control the six-axis industrial robot 1, which integrates the upper shell component positioning mechanism 7, to perform a positioning action according to the preset trajectory, that is, to move from the workbench 3 to the conveyor belt next to the workbench 3, so as to ensure that the pressing and assembly process of the electric bicycle instrument can be completed automatically. The specific pressing and assembly process is as follows:
[0038] Industrial robots at other workstations individually transfer the lower shell assembly from the lower shell assembly conveyor line to the positioning slot plate 53, and the lower shell assembly is stably placed in the groove of the positioning slot plate 53. Then, the PLC control cabinet 2 controls the six-axis industrial robot 1 to move the upper shell assembly positioning mechanism 7 above the upper shell assembly conveyor line. After that, the CCD vision camera 710 in the upper shell assembly positioning mechanism 7 takes a picture of the upper shell assembly conveyor line and sends the picture to the PLC control cabinet 2 in the form of an electrical signal. The PLC control cabinet 2 has a built-in image processing algorithm to perform grayscale conversion and edge detection preprocessing on the image, extract the contour features of the upper shell assembly, and then calculate the precise coordinates by mapping the pixel points to the actual space ratio to determine the precise position of the upper shell assembly. Then, the PLC control cabinet 2 feeds back the coordinate information of the upper shell assembly to the six-axis industrial robot 1, and controls the six-axis industrial robot 1 to adjust the angle of the upper shell assembly positioning mechanism 7 so that the position information of the upper shell assembly positioning mechanism 7 matches the position information of the upper shell assembly, and ensures that the upper shell assembly can be accurately picked up.
[0039] At this time, the six-axis industrial robot 1 places the upper shell component positioning mechanism 7 on the upper shell component, and the bottom end of the rubber suction cup 84 of the positioning component 8 contacts the upper surface of the upper shell component. At the same time, the distance sensor 711 measures the vertical distance between itself and the upper shell component, and the measured distance information is sent to the PLC control cabinet 2. If the distance measured by the distance sensor 711 reaches the preset distance value of the PLC control cabinet 2, the PLC control cabinet 2 controls the blower-pump dual-purpose air pump 94 and the electric push rod 10 to work. The moving end of the electric push rod 10 retracts, and the moving end of the electric push rod 10 drives the first rubber piston 11 to move upward, so that a negative pressure ring is formed inside the hollow cylinder 71. The negative pressure environment, driven by the third rubber piston 74, causes the moving rod 72 to retract, thereby bringing the two clamping plates 73 closer together and positioning and adjusting the position of the upper shell assembly. This ensures that the upper shell assembly can be easily picked up by the positioning component 8 under negative pressure. The two clamping plates 73 also provide limiting constraints on both sides of the upper shell assembly, ensuring that the upper shell assembly is stable when picked up by the positioning component 8. Furthermore, the dual-purpose air pump 94 activates the suction mode, drawing air from the four negative pressure suction cylinders 81 through the air supply box 91, the second air pipe 88, the connecting hose 87, and the U-shaped pipe 86, continuously generating a negative pressure environment inside the four negative pressure suction cylinders 81. Simultaneously, pressure sensors... The pressure sensor 85 detects the negative pressure value inside the negative pressure suction cylinder 81 and converts it into an electrical signal, which is then transmitted to the PLC control cabinet 2. If the negative pressure value detected by the four pressure sensors 85 is lower than the preset negative pressure threshold of the PLC control cabinet 2, the PLC control cabinet 2 controls the six-axis industrial robot 1 to transfer the upper shell assembly picked up by the positioning component 8 under negative pressure to directly above the lower shell assembly. Utilizing this negative pressure environment, the rubber suction cup 84 can firmly adhere to the surface of the upper shell assembly, preventing it from falling during transfer. After the positioning component 8 picks up the upper shell assembly under negative pressure, the suction force inside the hollow cylinder 71 gradually increases as the moving end of the electric push rod 10 continues to move upwards. The tendency of the moving rods 72 to move towards each other is enhanced. The moving rods 72 drive the clamping plate 73 to clamp the upper shell assembly more stably. After the upper shell assembly is clamped and positioned, the six-axis industrial robot 1 moves the upper shell assembly to directly above the lower shell assembly placed on the positioning slot plate 53 through the upper shell assembly positioning mechanism 7, and pauses for a period of time (e.g., 15 seconds). During this pause, the operator connects the wiring harness of the upper shell assembly to the lower shell assembly. After this period of time is over, the PLC control cabinet 2 controls the upper shell assembly positioning mechanism 7 to move down through the six-axis industrial robot 1, so that the upper shell assembly can be stably and reliably pressed and assembled with the lower shell assembly in the upper shell assembly positioning mechanism 7.
[0040] In the initial stage of pressing, due to the reaction force of the lower shell assembly, the upper shell assembly will slide upward within the upper shell assembly positioning mechanism 7. At this time, the pressing plate 78 and the arc-shaped pressing block 75 are in contact with the upper surface of the upper shell assembly and apply a uniform pressing force to the upper shell assembly, so that the pressing force of the upper shell assembly is uniform. At the same time, due to the reverse resistance of the pressing plate 78 and the arc-shaped pressing block 75, it can be ensured that the lower pressing degree of the upper shell assembly is in place, and the upper shell assembly and the lower shell assembly are accurately engaged, without the occurrence of local warping due to insufficient pressure. This design enables the pressing and assembly of electric bicycle instruments to be completed automatically, and the pressing force is evenly distributed, the pressing and assembly is in place, and there is no local warping defect. It not only improves the convenience, quality and efficiency of pressing and assembling electric bicycle instruments, but also reduces the labor intensity of workers.
[0041] While the positioning component 8 picks up the upper shell component under negative pressure, the PLC control cabinet 2 controls the normally closed solenoid valve 57 to be energized and started for a period of time (e.g., 10 seconds). In particular, during the suction process of the dual-purpose air pump 94, the second air pipe 88 also sucks air from the hollow block 52 through the first air pipe 58 and the opened normally closed solenoid valve 57, so that a negative pressure environment is formed inside the hollow block 52. Then, the negative pressure environment drives the clamping rod 54 to move through the second rubber piston 55. The two clamping rods 54 moving in opposite directions clamp the lower shell component. The clamping rods 54 avoid damage to the surface of the lower shell component through the protective rubber block 13, ensuring the stability of the lower shell component and the upper shell component during the pressing assembly, thereby ensuring the accuracy of the pressing assembly.
[0042] After the upper and lower shell components are pressed together and assembled, the PLC control cabinet 2 controls the operation of the dual-purpose air pump 94 and the normally closed solenoid valve 57. The normally closed solenoid valve 57 is energized and opened for a period of time (e.g., 10 seconds), while the dual-purpose air pump 94 starts the blowing mode. The dual-purpose air pump 94 draws outside air into the second air pipe 88 through the air supply box 91 and the dustproof mesh 16. The air in the second air pipe 88 enters the hollow block 52 through the first air pipe 58 and the opened normally closed solenoid valve 57. At this time, the air pressure, combined with the restoring force of the reset spring 56, drives the clamping rod 54 to move away from each other, releasing the clamping rod 54 from the lower shell component. The upper shell component positioning mechanism 7 clamps and transfers the assembled electric bicycle instrument to the belt conveyor on the production line. After the upper shell component positioning mechanism 7 places the assembled electric bicycle instrument on the corresponding belt conveyor, the PLC control cabinet 2 controls the extension of the moving end of the electric push rod 10 to release the restriction of the clamping plate 73 on the electric bicycle instrument, making it convenient to transfer the assembled electric bicycle instrument to other workstations.

[0043] When the dual-purpose air pump 94 starts blowing, the PLC control cabinet 2 also controls the semiconductor cooler 99 to work. The semiconductor cooler 99 lowers the temperature of the metal mesh block 96. The air blown by the dual-purpose air pump 94 is cooled (e.g., reduced by 10 degrees Celsius) when it passes through the low-temperature metal mesh block 96. The low-temperature air is then filtered and purified by the sponge block 97 and the filter plate 98. The clean low-temperature air enters the second air pipe 88, and then some of the air in the second air pipe 88 is injected into the PLC control cabinet 2 through the third air pipe 14, which accelerates the airflow inside the PLC control cabinet 2. At the same time, the low-temperature air accelerates the heat exchange inside the PLC control cabinet 2, improving the heat dissipation effect of the PLC control cabinet 2. Finally, the cooled air is ejected through the one-way jet nozzle 15. This structure enables rapid cooling to ensure the smooth and reliable operation of the electronic components inside the PLC control cabinet 2, avoiding jamming, and ensuring the continuous and stable control of the six-axis industrial robot 1. This mechanism enables the device to have the function of automatic and efficient cooling of the PLC control cabinet 2, improving the reliability of the device's automated control, and ensuring the effect of the electric bicycle instrument pressing assembly.
