Description

Technical Field

[0001] The invention relates to the technical field of color-sensitive sensor assembly, in particular to automatic assembly equipment for color-sensitive sensors. Background Art

[0002] A color sensor is another name for a color sensor, which is a sensor that detects color by comparing the color of an object with a previously taught reference color.

[0003] The color sensor is mainly composed of a light source, a filter, a photosensitive element and a signal processing circuit. The light source, the filter, the photosensitive element and the signal processing circuit are placed inside the color sensor, and then the side cover is used to protect the components.

[0004] At present, there are several problems in the process of assembling color sensors: 1. The assembly of the color sensor side cover is mostly carried out by conveyor belt, and the conveyed sensor shell is sometimes turned upside down, making the positioning of the side cover inaccurate. It is necessary to manually adjust the direction of the sensor shell, resulting in low assembly efficiency of the color sensor side cover; 2. When assembling the color sensor side cover, the conveyor belt will stop running. However, when the conveyor belt stops, the positioning deviation of the sensor housing is often too large, resulting in the inability to install the side cover and the housing. 3. After the workers have assembled the side covers, some of them are not fully installed. The assembly workers will mix the color sensors that are not fully installed with the sensors that are installed, and then transport them to the next station together, resulting in high intensity of sensor quality inspection work.

When in use, First, the sensor side covers 101 on the left and right sides are respectively placed in two assembly modules 5. When the sensor housing 102 assembled internally is transmitted from the outside and transported to the conveyor belt 7, the conveyor belt 7 is started to transport the sensor housing 102. The distance between the two adjacent sensor housings 102 is adjusted by the distance adjustment module 3. The replacement module 4 corrects the sensor housing 102 placed upside down. When transported to the limit module 8, the limit module 8 positions the sensor housing 102. Then, the assembly module 5 is used to assemble the sensor side covers 101 and the sensor housing 102 on the left and right sides. Finally, the discharge module 6 is used for screening to screen out defective sensors, so that the sensors transported are all qualified products, reducing the quality inspection pressure. A combination of multiple modules is used to realize the positioning and installation of the sensor side covers, reduce the loss during the installation of the sensor side covers, and thus reduce the production cost of the factory.

In the process of the slide 304 moving downward, the slide 304 will move downward synchronously with the distance adjusting cylinder 311, so that the distance adjusting cylinder 311 is inserted between two adjacent sensor housings 102, thereby pushing the two sensor housings 102 to move. The downward movement of the distance adjusting cylinder 311 will move the pull rod frame 312 downward synchronously, so that the first inclined surface 313 squeezes the sensor nut 103 to drive the sensor housing 102 to move, so that the sensor housing 102 will not enter the replacement module 4, and at the same time, a certain distance is created between the two adjacent sensor housings 102 to avoid the situation where the inertia of the sensor housing in contact when the conveyor belt stops is large and causes inaccurate positioning, which is convenient for subsequent processing.

[0028] Among them, the power mechanism includes a mounting frame 306, which is fixed to the top of one of the first limit frames 301 by bolts, and a pitch-adjusting motor 315 is fixed to one side of the mounting frame 306 by bolts, and the output shaft of the pitch-adjusting motor 315 passes through the mounting frame 306 and is key-connected to the turntable 305, and a guide column 314 is fixed to one side of the turntable 305 by bolts, and a guide frame 307 is welded to one side of the slide 304, and a guide groove 308 is provided on one side of the guide frame 307, and the guide column 314 moves in the guide groove 308, and the pitch-adjusting motor 315 is started, and the pitch-adjusting motor 315 drives the turntable 305 to rotate, thereby driving the guide column 314 to do a circular operation and move in the guide groove 308, and then driving the slide 304 to reciprocate up and down.

Two arc rods 407 are welded at both ends of the positioning frame 404, and the spacing between the two arc rods 407 at the same end is not less than the diameter of the sensor nut 103, and the arc rods 407 are welded to the two ends of the positioning frame 404. The distance between the lowest end of the rod 407 and the top of the sensor housing 102 is not less than the height of the sensor nut 103. When the sensor housing 102 is placed upside down, the sensor housing 102 will first squeeze the arc-shaped rod 407 at one end, so that the positioning frame 404 moves upward. When the sensor nut 103 enters the rightmost side of the groove 405, the arc-shaped rod 407 at the leftmost end is out of contact with the sensor housing 102. Under the action of gravity, the positioning frame 404 will move downward, so that the groove 405 can clamp the sensor housing 102, so that the sensor housing 102 Unable to continue moving to the right, the replacement motor 402 is then started to rotate the rotating frame 403 to a certain angle, thereby driving the sensor housing 102 to flip over, and the sensor housing 102 is continued to be driven to move to the right through the conveyor belt 7, so that the sensor housing 102 squeezes the arc rod 407 on the right, and then the positioning frame 404 moves upward, and the contact groove 405 limits the sensor nut 103, which can automatically adjust the angle of the sensor housing 102, thereby facilitating the assembly and positioning of the subsequent sensor side cover 101, thereby improving the assembly accuracy of the device.

When the U-shaped frame 802 moves downward, the sensor housing 102 squeezes the slide plate 804 to slide on one side of the U-shaped frame 802. When the slide plate 804 loses contact with the sensor housing 102, the elastic plate 803 that has been squeezed and deformed recovers, thereby driving the slide plate 804 to move downward, and then the sensor housing 102 is located between the slide plate 804 and the U-shaped frame 802, so that the sensor housing 102 will not move, thereby facilitating the installation of the sensor side cover 101.

[0035] The present invention is divided into the following steps when used: S1: Place the sensor side covers 101 on the left and right sides into the two discharge chambers 513 respectively, and when the sensor housing 102 assembled inside is transported from the outside to the conveyor belt 7, start the conveyor belt 7 to transport the sensor housing 102; S2: The conveyor belt 7 first conveys the sensor housing 102 to the distance adjustment module 3, and starts the distance adjustment motor 315. The distance adjustment motor 315 drives the turntable 305 to rotate, thereby driving the guide column 314 to make a circular motion and move in the guide groove 308, thereby driving the slide 304 to reciprocate up and down; S3: When the slide 304 moves downward, the slide 304 will move downward with the distance adjusting cylinder 311 synchronously, so that the distance adjusting cylinder 311 is inserted between two adjacent sensor housings 102, thereby pushing the two sensor housings 102 to move. The distance adjusting cylinder 311 moves downward with the pull rod frame 312 synchronously, so that the first inclined surface 313 squeezes the sensor nut 103 to drive the sensor housing 102 to move, so that the sensor housing 102 will not enter the replacement module 4, and at the same time, there is a certain distance between the two adjacent sensor housings 102; S4: Then the conveyor belt 7 conveys the sensor housing 102 to the exchange module 4, and the sensor housing 102 first squeezes the arc-shaped rod 407 at one end, so that the positioning frame 404 moves upward. When the sensor housing 102 moves to the right, the sensor housing 102 continues to squeeze the arc-shaped rod 407 at the other end, so that the positioning frame 404 does not fall. When the sensor housing 102 leaves the exchange module 4, the positioning frame 404 is out of contact with the sensor housing 102, and the positioning frame 404 recovers under the action of gravity; S5: Then the conveyor belt 7 will convey the sensor housing 102 to the assembly module 5, and start the limit cylinder 801 to make one end of the U-shaped frame 802 lower than the top of the sensor housing 102. When the U-shaped frame 802 moves downward, the sensor housing 102 will squeeze the slide plate 804 to slide on one side of the U-shaped frame 802. When the slide plate 804 is out of contact with the sensor housing 102, the elastic plate 803 that has been squeezed and deformed recovers, thereby driving the slide plate 804 to move downward, and then the sensor housing 102 is located between the slide plate 804 and the U-shaped frame 802, and then the sensor housing 102 is positioned; S6: Start the two assembly cylinders 502 so that the first push plate 506 pushes the bottom sensor side cover 101 to move toward the sensor housing 102, and the sensor side cover 101 is installed on both sides of the sensor housing 102 by the first push plate 506, thereby completing the assembly of the sensor body 1; S7: Then the conveyor belt 7 will convey the assembled sensor body 1 to the discharging module 6, and the sensor side cover 101 that is not installed in place will protrude from the sensor housing 102, so as to be guided by the third inclined surface 604, move to the top of the second limiting frame 601, and be pushed to the second push plate 603 by the next sensor body 1; S8: Start the unloading cylinder 602, so that the second push plate 603 pushes the sensor body 1 located above the second limit frame 601 to fall, and then falls to one side of one of the second limit frames 601. The sensor that has not been installed in place will continue to be driven and transported by the conveyor belt 7, and under the action of the guide plate 605, it moves to another workstation to complete the screening of the sensor body 1.
