Description

Technical Field

[0001] The present invention relates to the field of industrial vision technology, and in particular to a sponge and code sticking combined machine based on industrial vision. Background Art

[0002] In the process of sticking sponge on the workpiece, a sponge sticking and coding combination device is usually used for sticking, that is, the sponge sticker is sucked by a suction plate with an adsorption function, and then the suction plate is controlled to drive the sponge sticker to move above the workpiece to be stuck, and the suction plate is pressed on the surface of the workpiece to make the sponge sticker completely stick to the surface of the workpiece. However, when the surface of the workpiece is curved, the conventional suction plate cannot completely stick to the curved surface of the workpiece, which easily makes the sponge sticker and the workpiece not stick tightly, reducing the quality of the mounting. At the same time, when the size of the sponge sticker is small, the sponge sticker cannot completely cover the bottom of the suction plate, thereby reducing the suction force of the suction plate, which causes the sponge sticker to separate from the suction plate, resulting in missed mounting.

[0038] It also includes an elastic member 206 and an airbag 207; the first fixed block 9001 on the sponge block 9 is configured to be slidably connected to the inner wall of the suction plate 8; an elastic member 206 is fixedly connected between each first fixed block 9001 and the upper side wall of the cavity 8001, and the elastic member 206 is a spring telescopic rod; an airbag 207 is fixedly connected between each first fixed block 9001 and the lower side wall of the cavity 8001; the airbag 207 is connected to the external air supply device through a pipeline; the airbag 207 is configured to expand upward.

[0039] The upper side of the workpiece 4 is provided with an arc surface 4001, and the left and right sides of the workpiece 4 are provided with rounded corners 4002. The following is a detailed description of the process of attaching sponge and QR code to the workpiece 4 of the above shape:

[0040] First, the workpiece 4 is placed on the loading conveyor belt in sequence, and then the workpiece 4 is grabbed and placed on the fixed workstation 3001 on the front side through the workpiece loading mechanism 2. Based on the view from top to bottom, the electric control turntable 3 is controlled to rotate 90 degrees counterclockwise, thereby driving the fixed workstation 3001 on the front side and the workpiece 4 to the right. At this time, the dual-axis movable guide rail 6 is controlled to drive the first fixed frame 7, the suction plate 8 and its connecting parts to move to the right and downward, so that the two suction plates 8 are aligned with the left and right ends of the sponge patch transmitted by the sponge feeding flyer 5, and then the external air pump device is controlled to start pumping air from the exhaust hole 8002, and the sponge patch covers the air inlet on the lower side of the suction plate 8. In this way, air is pumped by the external air pump device, so that the air in the cavity 8001 passes through the exhaust hole 8002. The suction plate 8 and the pressure plate 10 are pressed together by the suction plate 8 and the pressure plate 10, and then the external vacuum device is controlled to stop vacuuming, so that the negative pressure adsorption effect of the sponge patch in the cavity 8001 disappears, and then the suction plate 8 and the pressure plate 10 are driven by the dual-axis movable guide rail 6 to move downward. The pressing plate 10 moves upward, thereby separating the suction plate 8 from the sponge sticker on the surface of the workpiece 4, thus completing the sponge sticker placement process, and then based on looking from top to bottom, control the electric control turntable 3 to continue to rotate 90 degrees counterclockwise, so that the workpiece 4 with the sponge sticker is facing the rear side, and then control the code sticking mechanism 12 to absorb the QR code sticker transmitted by the QR code feeding flyer 11, and stick the QR code on the workpiece 4 through the code sticking mechanism 12, thus completing the QR code placement process, and then based on looking from top to bottom, control the electric control turntable 3 to continue to rotate 90 degrees counterclockwise, so that the workpiece 4 with the QR code is facing the left side, and then the workpiece unloading mechanism 13 removes the workpiece 4 on the fixed station 3001 facing the left and places it on the unloading conveyor belt, and then the workpiece unloading mechanism 13 removes the workpiece 4 on the fixed station 3001 facing the left side ... The material conveyor belt transfers the workpiece 4, thus completing the unloading process of the workpiece 4. During this process, every time the electric turntable 3 rotates 90 degrees, the workpiece loading mechanism 2 will grab a workpiece 4 on the loading conveyor belt to the fixed station 3001 facing the front of the electric turntable 3, and the workpiece unloading mechanism 13 will grab the workpiece 4 on the fixed station 3001 facing the left side of the electric turntable 3 to the unloading conveyor belt, thus realizing the continuous sponge and QR code sticking process of the workpiece 4. On this basis, an industrial camera is installed on the first fixed frame 7, so that the movement and positioning accuracy of the first fixed frame 7 is improved by the camera. At the same time, the position and shape of the sponge patch are accurately identified by the camera to ensure the accuracy of the sponge patch during the bonding process.

[0041] When the workpiece 4 is in the process of attaching the sponge patch to the workpiece 4, when the surface of the workpiece 4 is an arc-shaped surface 4001, the conventional suction plate 8 cannot completely fit the arc-shaped surface 4001, so that the sponge patch is not tightly attached to the workpiece 4, reducing the attachment effect of the sponge patch. For this reason, a sponge block 9 is installed in the cavity 8001. When the external air pump device starts to pump air, the outside air enters the cavity 8001 through the sponge block 9 and is then sucked away by the external air pump device. In this way, the dust and other impurity particles in the air are intercepted by the sponge block 9 to prevent the dust from entering the exhaust pipe through the cavity 8001, thereby causing the exhaust pipe to be blocked and affecting the normal operation of the suction plate 8. Moreover, when the suction plate 8 and the pressure plate 10 move downward to contact the workpiece 4, since the sponge block 9 protrudes from the bottom of the suction plate 8 and the pressure plate 10 is made of sponge material, the sponge block 9 and the pressure plate 10 can be deformed after being compressed, and then the suction plate 8 and the pressure plate 10 are controlled. Continue to move downward so that the sponge block 9 and the pressure plate 10 are pressed and fit on the curved surface 4001, so that the sponge patch between the suction plate 8 and the workpiece 4 is completely fit on the curved surface 4001, thereby improving the fit between the sponge patch and the workpiece 4, and thus improving the mounting quality of the workpiece 4. Furthermore, since the workpieces 4 are of different sizes, the sponge patches also have different sizes. To this end, by controlling the electric slider 202 to slide left and right on the slide rail 201, the connecting rod 203, the suction plate 8 and the sponge block 9 are driven to slide left and right synchronously, so that the distance between the two suction plates 8 can be adjusted, thereby facilitating the suction plate 8 to absorb sponge patches of different sizes and improving the adaptability to different sponge patches. In addition, by setting the second fixed block 1001 to be engaged with the first fixed frame 7, it is convenient to remove the pressure plate 10 from the first fixed frame 7, and thus it is convenient to replace pressure plates 10 of different sizes, so as to adapt to the different spacing between the two suction plates 8.

[0042] On this basis, when the sponge block 9 and the pressure plate 10 are fitted on the curved surface 4001, the middle part of the sponge patch is completely fitted with the curved surface 4001, and the sponge block 9 and the pressure plate 10 cannot continue to be compressed downward. If the left and right sides of the workpiece 4 are provided with rounded corners 4002, the sponge block 9 cannot be completely fitted with the rounded corners 4002, so that there is still a gap between the left and right ends of the sponge patch and the rounded corners 4002. For this reason, by setting the connecting rod 203 as an electric push rod, by controlling the telescopic end of the connecting rod 203 to move downward, the suction plate 8 and the sponge block 9 are mobilized to move downward synchronously. In this way, compared with the conventional suction plate 8 structure, the suction plate 8 moves downward to make the sponge block 9 fit downward with the rounded corner 4002, so that the left and right sides of the sponge patch are completely fitted with the rounded corners 4002, thereby improving the adaptability of the suction plate 8 to the mounting of workpieces 4 of different shapes.

[0043] When the suction plate 8 absorbs a sponge patch with a smaller size in the front-to-back direction, the sponge patch is adsorbed in the middle of the sponge block 9. Due to the small size of the sponge patch, the front and back sides of the sponge block 9 are in an open state. In this way, the outside air can still enter the cavity 8001 from the front and back sides of the sponge block 9, increasing the pressure in the cavity 8001, thereby reducing the suction force of the sponge patch. Therefore, the compressed air is transported to all the sealed cavities 20401 through the pipeline through the external air pump device to increase the air pressure in the sealed cavity 20401. This pushes the front slide 205 to move backward and pushes the rear slide 205 to move forward, so that the slides 205 are respectively attached to the front and rear sides of the sponge block 9, sealing the part of the sponge block 9 not covered by the sponge patch. In this way, the sealed cavity 20401 is inflated by the external air pump device, reducing the flow of external air entering the cavity 8001, thereby reducing the negative pressure loss in the cavity 8001, and improving the suction force of the suction plate 8 when adsorbing small-sized sponge patches, thereby improving the adsorption adaptability of the suction plate 8 to sponge patches of different sizes.

[0044] On this basis, when the suction plate 8 is in a non-working state, the sponge block 9 is exposed to the outside air for a long time, and the moisture and dust in the air can easily enter the sponge block 9, resulting in agglomeration and clogging of the sponge block 9, thereby reducing the suction force of the suction plate 8. For this reason, when the suction plate 8 is in a non-working state, the air bag 207 is continuously inflated by an external air pump device, so that the air bag 207 is inflated and expanded upward, thereby pushing the first fixed block 9001, the sponge block 9, the second fixed frame 204 and the slide plate 205 to move upward, so that the sponge block 9 is completely retracted into the cavity 8001, and The elastic member 206 is compressed by force, and at the same time, air is continuously inflated into the sealed cavity 20401 through an external air pump device, so that the slide plates 205 on the front and rear sides move toward each other and fit together, thereby sealing the bottom of the sponge block 9. At this time, the slide plate 205 fits with the bottom of the suction plate 8. In this way, the suction plate 8 and the slide plate 205 work together to form a sealed space in the cavity 8001, so that the sponge block 9 is protected in the cavity 8001 when it is not working, thereby avoiding the internal agglomeration and blockage of the sponge block 9 due to long-term exposure to the outside air, thereby ensuring that the suction force of the suction plate 8 is not affected.

[0045] Example 2

[0046] On the basis of Example 1, Figure 6-Figure 8 As shown, each slide plate 205 is provided with a groove 20501; a connecting hole 20502 is provided at the bottom of each groove 20501; an exhaust port 20403 is provided at the bottom of each second fixing frame 204; the exhaust port 20403 is connected to an external dust collection device; the four end surfaces of the groove 20501 are set as fitting surfaces 20503; the fitting surfaces 20503 are set to fit with the four edges of the bottom surface of the sponge block 9.

[0047] Furthermore, in order to improve the cleaning efficiency of the sponge block 9, the airbag 207 is configured to expand circumferentially; a slide groove is provided on the upper side of each first fixed block 9001; and each elastic member 206 is configured to slide in the slide groove of an adjacent first fixed block 9001.

[0048] Furthermore, in order to prevent dust and impurities from remaining in the groove 20501, the bottom surface of the groove 20501 is set to be an inclined surface, and the connecting hole 20502 is located at the lowest point of the inclined surface.

[0049] When the suction plate 8 is in a continuous working state, the outside air continuously enters the cavity 8001 from the inside of the sponge block 9. In this way, the dust impurities intercepted on the surface of the sponge block 9 will continue to increase. When there are too many dust impurities, they will clog the small holes on the sponge block 9, causing the suction force of the suction plate 8 to decrease. For this reason, every time a sponge patch of a workpiece 4 is completed, the suction plate 8 needs to be reset and moved to the sponge feeding flyer 5 to absorb the next sponge patch. During the reset movement, the airbag 207 can be controlled to inflate and expand to shrink the sponge block 9 into the cavity 8001, and the front and rear slides 205 can cover the bottom of the suction plate 8, so that the sponge block 9 is in the sealed cavity 8001. At this time, the connecting hole 20502 and the exhaust port 20403 are in a connected state. , and then control the external air pump device to blow air into the cavity 8001, so that the airflow blows downward through the sponge block 9, and then enters the groove 20501 from the bottom of the sponge block 9, and then the airflow passes through the connecting hole 20502 and the exhaust port 20403 in turn, and is finally discharged into the external dust collection device. In this way, the sponge block 9 is reversely cleaned from top to bottom by the airflow, so that the dust attached to the surface of the sponge block 9 is blown off by the airflow, and then falls into the groove 20501, and then follows the flow of the airflow and is discharged from the exhaust port 20403, thereby cleaning the dust on the surface of the sponge block 9. When the dust cleaning is completed, control the external air pump device to extract air from the airbag 207 to restore the airbag 207 to its original state, so that the elastic member 206 gradually returns to its original position, pushing the sponge block 9 and the first A fixed block 9001 moves downward to the initial position, and at the same time controls the external air pump device to extract air from the sealed chamber 20401, so that the front and rear slides 205 move opposite to each other, so that the bottom of the sponge block 9 is exposed to the air, so that the sponge block 9 is restored to its initial state, which is convenient for the next absorption of the sponge patch. Compared with the conventional cleaning method of the sponge block 9, the sponge block 9 is cleaned by reverse airflow, and the dust and impurities are collected and discharged, eliminating the process of manual cleaning of the sponge block 9 and reducing the workload of the staff. At the same time, by cleaning the sponge block 9 during the resetting movement of the suction plate 8, the operation of stopping the machine when cleaning the sponge block 9 is eliminated, so that the suction plate 8 can work continuously, thereby improving the efficiency of sponge patch placement. On this basis, The airbag 207 is configured to expand in the circumferential direction. During the process of reverse cleaning of the sponge block 9 by the air flow, the airbag 207 is repeatedly inflated and evacuated through the external air pump device, so that the airbag 207 is deformed back and forth in the circumferential direction, thereby causing the sponge block 9 to be compressed and rebounded back and forth in the front and rear directions, thereby causing the sponge block 9 to continuously shake. In this way, the falling of dust on the sponge block 9 is accelerated by shaking, thereby improving the cleaning effect of the dust on the sponge block 9. Furthermore, when the dust on the sponge block 9 falls into the groove 20501, by setting the bottom surface of the groove 20501 as an inclined surface, and the connecting hole 20502 being located at the lowest point of the inclined surface, when the airflow blows toward the groove 20501, the inclined surface on the groove 20501 guides the airflow to blow toward the connecting hole 20502.This prevents dust and impurities from accumulating in the groove 20501, further improving the cleaning effect of dust and impurities.
