Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically a multi-station positioning device and positioning method. Background Technology

[0002] During the glass processing, glass needs to be transported between processing steps. In the past, manual handling was mostly used, which was time-consuming and labor-intensive. Each piece of glass could only be processed one by one, resulting in low processing efficiency. Furthermore, when the glass was transported to the printing area, there might be errors in the position and angle of the glass, which could not be accurately aligned with the printing device. Direct printing would lead to deviations in the printed pattern, so additional alignment was required. Manual alignment of the glass with the printing device took a lot of time, affecting work efficiency.

[0003] Existing glass conveying and positioning devices consistently face the following problems:

[0004] 1. When glass is manually handled and positioned, the angle of the glass is prone to error during printing, resulting in poor printing quality.

[0005] 2. It can only process a single piece of glass at a time, resulting in low processing efficiency. Summary of the Invention

[0006] The present invention provides a multi-station positioning device and positioning method to solve the problems mentioned in the background art.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0008] A multi-station positioning device includes a first conveying device and a second conveying device arranged front and rear, both transporting glass in the same direction. The first conveying device has a feeding area for placing glass and a positioning and tilting mechanism for transporting glass along the X-axis. The second conveying device has a positioning and printing mechanism for printing glass. Furthermore, the first conveying device, the second conveying device, the positioning and tilting mechanism, and the positioning and printing mechanism are all electrically connected to a controller. The positioning and tilting mechanism moves the glass located in the feeding area laterally to the first conveying device on one side of the feeding area. When the number of laterally placed glass pieces reaches a predetermined quantity, the first conveying device is activated to transport multiple pieces of glass simultaneously.

[0009] Preferably, the first conveying device includes a first working frame, on which a plurality of rollers for transporting glass are provided. Each roller is provided with a gear on the same side end, and a chain is also provided on the first working frame and connected to each of the gears. A first motor is also connected to one end of the chain and is connected to a controller.

[0010] Preferably, the positioning and tilting mechanism includes two sets of parallel lead screws located below the rollers in the feeding area. A base is slidably connected between the two sets of lead screws. A first electric lifting rod is mounted on the base, and a U-shaped platform is mounted on the top of the first electric lifting rod. Both upward ends of the U-shaped platform can extend from the gap between the corresponding upper rollers, and the height of both upward ends of the U-shaped platform is higher than the diameter of the rollers. The mechanism also includes multiple first photoelectric sensors arranged laterally below the gaps between the rollers on one side of the feeding area. A cleaning machine for feeding glass into the feeding area is also provided on one side of the feeding area. There are a maximum of eight first photoelectric sensors. During operation, the working positions of the first photoelectric sensors can be adjusted to 1, 2, 4, or 8 according to the size of the glass to be processed. The cleaning machine is an existing integrated glass cleaning and discharging machine, which cleans the glass and then transports it to the feeding area.

[0011] Preferably, the length direction of each lead screw is the same as the length direction of the roller, a lead screw motor is connected to the same end of each lead screw, and the other end of each lead screw is movably installed with the first work frame, and each lead screw motor is connected to a controller.

[0012] Preferably, the second conveying device includes a second work frame with several conveyor belts, the spacing between adjacent conveyor belts being less than the width of the glass. Each conveyor belt has a second motor at one end for driving the corresponding conveyor belt, and each second motor is connected to a controller. After the first photoelectric sensor detects that the glass has arrived at the feeding area, it transmits the data to the controller. The controller then controls the first electric lifting rod to lift the glass via a U-shaped platform, while simultaneously moving the glass laterally out of the feeding area to a predetermined position and lowering it.

[0013] Preferably, the positioning and printing mechanism includes a lifting roller device located below the conveyor belt for aligning the glass. One side of the lifting roller device is also equipped with a lifting suction cup device for picking up and fixing the glass. Two second photosensitive sensors for positioning one side of the glass are located on one side of the lifting roller device, and a second photosensitive sensor for positioning the bottom edge of the glass is located on the other side of the lifting roller device. It also includes an electric slide rail mounted on a second work frame, and a printing device can be slidably mounted on the electric slide rail. The printing device performs printing work on the glass on different lifting roller devices by moving laterally along the electric slide rail, and the printing device can simultaneously print on one large-size glass or multiple small-size glass pieces.

[0014] Preferably, the lifting roller device includes a second electric lifting rod located below the lifting belt. An adjusting wheel is mounted on the top of the second electric lifting rod to extend from the gap between the conveyor belts and lift the glass after the second electric lifting rod operates. An adjusting wheel motor is located on one side of the adjusting wheel, and the conveying direction of the adjusting wheel is set at a 45° angle to the conveying direction of the conveyor belt. Both the adjusting wheel motor and the second electric lifting rod are connected to a controller. When the glass is positioned for the printing mechanism during transport, the second photoelectric sensor detects whether it is blocked by glass and transmits the detected data to the controller. The controller controls the second electric lifting rod to lift the adjusting wheel to contact the glass, and rotates the adjusting wheel motor to align the side and bottom edges of the glass with the corresponding second photoelectric sensors.

[0015] Preferably, the lifting suction cup device includes a third electric lifting rod located on one side of the second electric lifting rod. The top of the third electric lifting rod is equipped with a vacuum suction cup device for extending from the gap between the conveyor belts to fix the glass after the third electric lifting rod has been activated. Both the vacuum suction cup device and the third electric lifting rod are connected to a controller. The vacuum suction cup device is raised by the third electric lifting rod to adhere and fix the glass until the printing device finishes printing, at which point it descends and places the glass back onto the conveyor belt.

[0016] Preferably, multiple positioning printing mechanisms on the second conveying device are arranged in a straight line at predetermined intervals, and the arrangement direction of the positioning printing mechanisms is perpendicular to the transport direction of the conveyor belt. The maximum number of positioning printing mechanisms is eight. By having eight parallel positioning printing mechanisms work simultaneously, multi-station simultaneous processing is achieved, effectively improving processing efficiency. A movable baffle is also provided between the first and second conveying devices to vertically separate them after operation. The movable baffle is parallel to the first and second conveying devices on both sides. A fixed shaft is provided on the side of the movable baffle closest to the first conveying device, and a baffle motor is installed at one end of the fixed shaft and connected to a controller. By operating the baffle motor, the movable baffle is erected, and the front end of the glass contacts the movable baffle to align its angle, thereby achieving the effect of aligning the glass before it enters the second conveying device from the first conveying device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The glass is aligned by using a movable baffle, and the position of the aligned glass is finely adjusted by a positioning printing mechanism set on the second conveying device, thereby improving the positional accuracy of the glass, making it more compatible with the printing range, and improving the printing quality.

[0019] 2. This device is equipped with an adjustment wheel structure. During printing, if the product position is not aligned, the second electric lifting rod will raise the adjustment wheel to adjust the glass position in conjunction with the second photoelectric sensor.

[0020] 3. Multiple positioning printing mechanisms are set on the second conveying device, which can support printing on up to 8 pieces of glass. The glass is horizontally arranged and conveyed to each positioning printing mechanism through the positioning and swaying mechanism, resulting in fast glass printing speed and high efficiency.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6A multi-station positioning device includes a first conveying device 1 and a second conveying device 2 arranged front and rear and transporting glass 7 in the same direction. The first conveying device 1 has a feeding area for placing the glass 7 and a positioning and tilting mechanism 3 for transporting the glass 7 along the width direction of the first conveying device 1. The second conveying device 2 has a positioning and printing mechanism 4 for printing the glass 7. Furthermore, the first conveying device 1, the second conveying device 2, the positioning and tilting mechanism 3, and the positioning and printing mechanism 4 are all electrically connected to a controller. The positioning and tilting mechanism 3 moves the glass 7 located in the feeding area laterally to the first conveying device 1 on one side of the feeding area. When the number of laterally placed glass 7 reaches a predetermined number, the first conveying device 1 is activated to transport multiple glass 7 simultaneously.

[0030] The first conveying device 1 includes a first working frame 12, on which a plurality of rollers 11 for transporting glass 7 are provided. Each roller 11 is provided with a gear 14 on the same side end. The first working frame 12 is also provided with a chain 15 connected to each gear 14. A first motor 13 is also connected to one end of the chain 15. The first motor 13 is connected to a controller.

[0031] The positioning and swaying mechanism 3 includes two sets of parallel lead screws 31 located below the rollers 11 in the feeding area. A base 32 is slidably connected between the two sets of lead screws 31. A first electric lifting rod 33 is provided on the base 32, and a U-shaped platform 34 is provided on the top of the first electric lifting rod 33. The two upward ends of the U-shaped platform 34 can extend from the gap between the corresponding upper rollers 11, and the height of the two upward ends of the U-shaped platform 34 is higher than the diameter of the rollers 11. It also includes a first photoelectric sensor 16. There are multiple first photoelectric sensors 16 arranged laterally below the gaps between the rollers 11 on one side of the feeding area. A cleaning machine 6 for feeding materials into the feeding area is also provided on one side of the feeding area. There are a maximum of 8 first photoelectric sensors 16, and the working positions of the first photoelectric sensors 16 can be adjusted to 1, 2, 4, and 8 according to the size of the glass 7 to be processed. The cleaning machine 6 is an existing glass 7 cleaning machine 6 that integrates cleaning and discharging. The glass 7 is cleaned by the cleaning machine 6 and then transported to the feeding area.

[0032] The length direction of each lead screw 31 is the same as that of the roller 11. Each lead screw 31 is connected to a lead screw 31 motor on the same side end, and the other end of each lead screw 31 is movably installed with the first work frame 12. Each lead screw 31 motor is connected to a controller.

[0033] The second conveying device 2 includes a second work frame 21, on which several conveyor belts 23 are provided. The spacing between each adjacent conveyor belt 23 is less than the width of the glass 7. Each conveyor belt 23 has a second motor 22 at one end for driving the corresponding conveyor belt 23, and each second motor 22 is connected to a controller. After the first photoelectric sensor 16 detects that the glass 7 has arrived at the feeding area, it transmits the data to the controller. The controller controls the first electric lifting rod 33 to lift the glass 7 through the U-shaped platform 34, and at the same time, it moves the glass 7 laterally out of the feeding area to the predetermined position and puts the glass 7 down.

[0034] The positioning and printing mechanism 4 includes a lifting roller device located below the conveyor belt 23 for aligning the glass 7. One side of the lifting roller device is also equipped with a lifting suction cup device for picking up and fixing the glass 7. Two second photosensitive sensors 43 for positioning one side of the glass 7 are located on one side of the lifting roller device, and a second photosensitive sensor 43 for positioning the bottom edge of the glass 7 is located on the other side of the lifting roller device. It also includes an electric slide rail 45 mounted on the second work frame 21, and a printing device 44 can be slidably mounted on the electric slide rail 45. The printing device 44 moves laterally along the electric slide rail to print on the glass on different lifting roller devices, and the printing device 44 can simultaneously print on one large-size glass or multiple small-size glass pieces.

[0035] The lifting roller device includes a second electric lifting rod 411 located below the lifting belt. A regulating wheel 41 is mounted on the top of the second electric lifting rod 411 to extend from the gap between the conveyor belts 23 and lift the glass 7 after the second electric lifting rod 411 is in operation. A regulating wheel 41 motor is located on one side of the regulating wheel 41, and the conveying direction of the regulating wheel 41 is set at a 45° angle to the conveying direction of the conveyor belt 23. Both the regulating wheel 41 motor and the second electric lifting rod 411 are connected to a controller. When the glass 7 is transported to the positioning printing mechanism 4, the second photosensitive sensor 43 detects whether it is blocked by the glass 7 and transmits the detected data to the controller. The controller controls the second electric lifting rod 411 to lift the regulating wheel 41 to contact the glass 7 and rotates it through the regulating wheel 41 motor to align the side and bottom edges of the glass 7 with the corresponding second photosensitive sensors 43.

[0036] The lifting suction cup device includes a third electric lifting rod 421 located on one side of the second electric lifting rod 411. The top of the third electric lifting rod 421 is equipped with a vacuum suction cup device 42 for extending from the gap between the conveyor belts 23 to fix the glass 7 after the third electric lifting rod 421 has been activated. Both the vacuum suction cup device 42 and the third electric lifting rod 421 are connected to a controller. The vacuum suction cup device 42 is raised by the third electric lifting rod 421 to adhere and fix the glass 7 until the printing device 44 finishes printing, at which point it descends and places the glass 7 back onto the conveyor belt 23.

[0037] The second conveying device 2 has multiple positioning printing mechanisms 4 arranged in a straight line at predetermined intervals, and the arrangement direction of the positioning printing mechanisms 4 is perpendicular to the transport direction of the conveyor belt 23. The maximum number of positioning printing mechanisms 4 is 8. By having 8 positioning printing mechanisms 4 arranged side by side work simultaneously, the effect of multi-station simultaneous processing is achieved, which effectively improves processing efficiency.

[0038] A movable baffle 5 is provided between the first conveying device 1 and the second conveying device 2 to vertically separate them after operation. The movable baffle 5 is parallel to the first conveying device 1 and the second conveying device 2 on both sides. A fixed shaft is provided on the side of the movable baffle 5 closest to the first conveying device 1. A baffle motor is installed at one end of the fixed shaft and is connected to a controller. The input control software can be connected to the controller to control the rotation angle and frequency of the fixed shaft to match the transport frequency or processing time of glass of different sizes. This achieves the initial positioning or straightening of glass of different sizes during transport. By operating the baffle motor, the movable baffle 5 is erected, and the front end of the glass 7 contacts the movable baffle 5 to straighten the angle, thereby achieving the effect of straightening the glass 7 before it enters the second conveying device 2 from the first conveying device 1. After the glass 7 is positioned with each of the second photosensitive sensors 43, the vacuum suction cup device 42 is raised by the third electric lifting rod 421 to adsorb and fix the glass 7 until the printing device 44 finishes printing and lowers back onto the conveyor belt 23, completing the printing process. This invention can print multiple glass 7s simultaneously at multiple stations and can accurately position each glass 7, resulting in good printing quality.

[0039] A positioning method for a multi-station positioning device as described above, characterized in that the method includes the following:

[0040] S1. After cleaning the glass 7, the cleaning machine 6 transports it to the feeding area of ​​the first conveying device 1. At the same time, the first photoelectric sensor 16 detects the glass 7 and transmits the data to the controller. The controller controls the positioning and swaying mechanism 3 to arrange the glass horizontally on the first conveying device 1.

[0041] S2. After the glass 7 is arranged to a predetermined quantity, the first conveying device 1 operates to convey the glass 7 to the second conveying device 2.

[0042] S3. Simultaneously, the movable baffle 5 operates in an upward vertical state. When passing between the first conveying device 1 and the second conveying device 2, the glass 7 is blocked by the movable baffle 5, thereby straightening the angle of the glass 7. Subsequently, the movable baffle 5 rotates to allow the glass 7 to pass through and enter the second conveying device 2.

[0043] S4, the glass 7 is conveyed to the position printing mechanism 4 below by the second conveying device 2.

[0044] S5. The positioning and printing mechanism 4 adjusts the position of the glass 7 by adjusting the adjustment wheel 41 to align it with each of the second photoelectric sensor 43, and then fixes and lifts the glass 7 by the vacuum suction cup device 42 to print.

[0045] In Example 1, the washing machine 6 cleans the glass 7 and transports it to the feeding area. After the first photoelectric sensor 16 detects that the glass 7 has arrived at the feeding area, it transmits the data to the controller. The controller controls the first electric lifting rod 33 to lift the glass 7 through the U-shaped platform 34. At the same time, it moves the glass 7 laterally out of the feeding area to the predetermined position and puts it down. After the glass 7 is arranged laterally, the first motor 13 drives the roller 11 to rotate through the meshing of the chain 15 and the gear 14, so as to achieve the effect of transporting multiple glass 7 at the same time. Before the glass 7 leaves the first conveyor device 1 and the second conveyor device 2, the baffle motor drives the movable baffle 5 to stand up. The front end of the glass 7 contacts the movable baffle 5 and is aligned at the right angle, so as to achieve the effect of aligning the glass 7 before it enters the second conveyor device 2 from the first conveyor device 1. When glass 7 is transported to the positioning printing mechanism 4, the second photosensitive sensor 43 detects whether it is blocked by glass 7 and transmits the detected data to the controller. The controller controls the second electric lifting rod 411 to raise the adjusting wheel 41 to contact glass 7. The motor of the adjusting wheel 41 rotates the glass 7 so that the side and bottom edges of the glass 7 are aligned with the corresponding second photosensitive sensors 43. After the glass 7 is positioned with each of the second photosensitive sensors 43, the third electric lifting rod 421 raises the vacuum suction cup device 42 to suction and fix the glass 7 until the printing device 44 finishes printing and lowers the glass 7 back onto the conveyor belt 23, completing the printing process.

[0046] In the second embodiment, when printing on a small area of ​​glass 7, the positioning and stacking mechanism 3 arranges the glass 7 horizontally in correspondence with each of the first photoelectric sensor 16 for transportation.

[0047] When printing on a large area of ​​glass 7, the position of glass 7 corresponds to the first photoelectric sensor 16 at station 1 and the first photoelectric sensor 16 at station 5. The first photoelectric sensors 16 at stations 2, 3, 4, 6, 7, and 8 are blocked, while stations 1 and 5 are not blocked. The first photoelectric sensors 16 at stations 1 and 5, which are not blocked, work to position the corresponding glass 7.
