Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, and in particular to a dual-platform barcode scanner. Background Technology

[0002] Many products require barcode scanning during the manufacturing process. A Chinese patent application (application number 202122054039.X) discloses a fully automated CCD rapid barcode scanning mechanism. This mechanism includes a worktable, an X-axis single-axis robot, a Y-axis single-axis robot, a sliding plate, a CCD camera, and a positioning mechanism. The X-axis single-axis robot and the positioning mechanism are mounted on the worktable. The Y-axis single-axis robot is slidably mounted on the X-axis robot. The sliding plate is slidably mounted on the side of the Y-axis robot. The CCD camera is slidably mounted on the upper part of the sliding plate on the side opposite to the Y-axis robot, with the camera lens facing downwards. The positioning mechanism is located directly below the CCD camera. While this patent enables automatic barcode scanning, it requires manual handling of the material tray, resulting in low automation, low production efficiency, and high labor costs and intensity.

[0003] Furthermore, Chinese patent application number 202320117215.6 discloses a barcode scanning mechanism for button batteries, including a worktable, an XYZ high-precision moving module, four adjustable-angle bar light sources, an industrial camera, and a barcode scanner. The worktable has a preparatory station and a scanning station. A gantry is located on each side of the scanning station, with the gantry facing each other. The XYZ high-precision moving module is mounted on the gantry, and the industrial camera is positioned above the scanning station. The industrial camera can move along the X, Y, and Z axes via the XYZ high-precision moving module. The four bar light sources are arranged around the scanning station above it, and a barcode scanner is located on one side of the scanning station. While this patent can achieve automatic scanning, it requires manual handling of the material tray, resulting in low automation, low production efficiency, and high labor costs and intensity.

[0004] Furthermore, Chinese patent application number 201711270458.9 discloses a dual-station barcode scanning testing device, which includes a base box, a bracket mounted on the upper surface of the base box, a testing platform, a barcode scanning device, and a testing mechanism. The testing platform is mounted on the upper surface of the cover plate of the base box. The bracket consists of a left side plate, a right side plate, a beam plate, and a rear side plate. The left and right side plates are respectively located on both sides of the upper surface of the testing platform. The rear surface of the rear side plate has a cylinder for driving the testing mechanism. The barcode scanning device consists of a housing and an optical barcode scanning module. A scanning port is opened at the front end of the housing, and the optical barcode scanning module is installed inside the scanning port. The optical barcode scanning module includes a light source, a receiver, and a lens. The light source and receiver are both installed at the bottom of the housing, and the lens is installed above the light source. Although this patent discloses a dual testing platform and realizes automatic barcode scanning, it still requires manual handling of the material tray, resulting in low automation, low production efficiency, and high labor costs and intensity.

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] like Figures 1 to 11As shown, the present invention provides a dual-platform barcode scanner, which includes a machine base 1, a feeding mechanism 2 and a receiving mechanism 3 arranged side by side on the front side of the machine base 1, two moving drive mechanisms 4 installed parallel to each other on the top surface of the machine base 1, a barcode reading device 5 installed on the top surface of the machine base 1 and located between the front ends of the two moving drive mechanisms 4, two platforms 6 respectively installed on the moving ends of the two moving drive mechanisms 4, a loading and unloading drive mechanism 7 installed on the machine base 1 and mounted above the feeding mechanism 2, the receiving mechanism 3 and the two platforms 6, a loading and unloading robot arm 8 installed on the execution end of the loading and unloading drive mechanism 7, and a barcode scanning mechanism 9 installed on the machine base 1 and mounted above the two platforms 6. The barcode scanning mechanism 9 is located behind the loading and unloading robot arm 8, and the feeding mechanism 2 and the receiving mechanism 3 are located in front of the two moving drive mechanisms 4.

[0032] In practical applications, the feeding mechanism 2 supplies a tray loaded with products to be scanned, the receiving mechanism 3 collects the tray after the products are scanned, the loading and unloading drive mechanism 7 drives the loading and unloading robot 8 to move above the feeding mechanism 2 and pick up the tray from the feeding mechanism 2 onto the platform 6 at the loading and unloading position, then the moving drive mechanism 4 drives the platform 6 along with the tray to the scanning position, the barcode reading device 5 scans / detects the barcode on the product carried by the tray and reads the product information, after the scanning is completed, the moving drive mechanism 4 drives the platform 6 along with the tray to move from the scanning position to the loading and unloading position, then the loading and unloading drive mechanism 7 drives the loading and unloading robot 8 to move above the platform 6 at the loading and unloading position and pick up the tray on the platform 6, and then place the tray at the receiving mechanism 3. Two moving drive mechanisms 4 drive two platforms 6 to move back and forth alternately between the loading / unloading position and the scanning position. This allows the two platforms 6 to move alternately to the loading / unloading position; that is, when one platform 6 is at the loading / unloading position, the other platform 6 is at the scanning position. The two platforms 6 take turns transporting the tray loaded with products to be scanned to the scanning position for scanning, greatly improving the efficiency of product scanning. In addition, when reading the bottom marking code on the bottom surface of the tray before or after scanning, the loading / unloading robot 8 moves the tray above the barcode reader of the barcode reader 5. The barcode reader of the barcode reader 5 reads the bottom marking code on the bottom surface of the tray to obtain the information of the tray, so that the information of the tray is matched with the information of the products carried on the tray, thereby realizing barcode binding and facilitating the positioning and tracking of the tray and / or the products on the tray. Of course, the feeding mechanism 2 can also directly supply products to be scanned, and the receiving mechanism 3 can also directly collect the scanned products. The barcode reader of the barcode reading device 5 reads the lower identification code on the bottom surface of the product to match the upper scanning information and the lower reading information of the product. This utility model can automatically realize the automatic feeding, lower reading, upper scanning and unloading of products or trays, which greatly improves the production efficiency of barcode scanning and reduces labor costs and labor intensity.

[0033] In this embodiment, the loading / unloading robot 8 includes a lifting drive mechanism 10 mounted on the execution end of the loading / unloading drive mechanism 7, a mounting frame 11 mounted on the lifting end of the lifting drive mechanism 10, and a plurality of first suction cups 12 mounted on the mounting frame 11. In practical applications, the lifting drive mechanism 10 drives the mounting frame 11 to lift and lower along with the plurality of first suction cups 12, which are used to grip the edges of the trays or products. The position of the first suction cups 12 on the mounting frame 11 is adjustable to accommodate products or trays of different specifications.

[0034] In this embodiment, the loading / unloading robot 8 also includes a lifting driver 13 mounted on the mounting frame 11 and a second suction cup 14 mounted on the lifting end of the lifting driver 13. The second suction cup 14 is located within a plurality of first suction cups 12, at the center of the plurality of first suction cups 12, and the suction surface of the second suction cup 14 can extend below the suction surface of the first suction cup 12. In practical applications, when the tray carries multiple products and it is necessary to read the bottom identification code on the bottom surface of the products carried on the tray, the loading / unloading drive mechanism 7 drives the second suction cup 14 on the loading / unloading robot 8 to move above the corresponding product. Then, the lifting driver 13 drives the second suction cup 14 to descend, so that the second suction cup 14 picks up the product. Then, the loading / unloading drive mechanism 7 drives the loading / unloading robot 8, along with the product picked up by the second suction cup 14, to move above the code reader of the code reading device 5, so that the code reader of the code reading device 5 reads the bottom identification code of the product to read the information on the bottom identification code of the product. Of course, it can read the code of each product among the multiple products carried by the tray to ensure that there are no problems such as missing or mixed materials, or it can randomly sample and read the codes of multiple products carried by the tray.

[0035] Specifically, the lifting drive 13 can be a cylinder.

[0036] In this embodiment, the scanning mechanism 9 includes a gantry frame 15 mounted on the machine base 1, a moving drive module 16 mounted on the top of the gantry frame 15, a lifting drive module 17 mounted on the moving end of the moving drive module 16, a lifting plate 18 mounted on the lifting end of the lifting drive module 17, a barcode scanner 19 mounted on the lifting plate 18, and a supplementary light source 20 mounted on the lifting plate 18. A scanning hole 21 is provided at the center of the supplementary light source 20, and the scanning end of the barcode scanner 19 extends into the scanning hole 21. Specifically, the supplementary light source 20 is a surface light source, and both the barcode scanner 19 and the barcode reader can be CCD cameras, barcode guns, or optical barcode scanning modules.

[0037] In practical applications, the lifting drive module 17 drives the lifting plate 18, along with the barcode scanner 19 and the supplementary light source 20, to lift and lower, thereby adjusting the focal length of the barcode scanner 19. The barcode scanner 19 first identifies the markings on the tray or product to determine the scanning position. The moving drive module 16 then drives the lifting drive module 17, along with the lifting plate 18, the barcode scanner 19, and the supplementary light source 20, to move to the scanning position. The supplementary light source 20 provides supplementary lighting to the products on the tray, enabling the barcode scanner 19 to accurately scan the markings on the products on the tray.

[0038] In this embodiment, the platform 6 includes a carrier plate 22 mounted on the moving end of the moving drive mechanism 4, an L-shaped positioning structure 23 disposed on the carrier plate 22, a first positioning mechanism 24 disposed on the carrier plate 22, and a second positioning mechanism 25 disposed on the carrier plate 22. The first positioning mechanism 24 is disposed opposite to one side of the L-shaped positioning structure 23, and the second positioning mechanism 25 is disposed opposite to the other side of the L-shaped positioning structure 23. The L-shaped positioning structure 23, the first positioning mechanism 24, and the second positioning mechanism 25 enclose a positioning space.

[0039] In practical applications, after the tray or product is placed in the positioning space, the first positioning mechanism 24 and the second positioning mechanism 25 cooperate to push the product to contact the L-shaped positioning structure 23, thereby positioning the tray or product in four directions to ensure the positional accuracy of the tray or product on the platform 6.

[0040] In this embodiment, a guide slope 26 is provided on the inner side of the top surface of the L-shaped positioning structure 23; the L-shaped positioning structure 23 includes multiple positioning blocks mounted on the carrier plate 22, the multiple positioning blocks are arranged in an L-shape, and the guide slope 26 is provided on the inner side of the top surface of the positioning blocks; or, the L-shaped positioning structure 23 includes two positioning reference plates mounted on the carrier plate 22, the two positioning reference plates are arranged in an L-shape, and the guide slope 26 is provided on the inner side of the top surface of the positioning reference plates. The provision of the guide slope 26 facilitates the placement of the tray or product in the positioning space; in addition, it realizes the modular assembly of the L-shaped positioning structure 23.

[0041] In this embodiment, both the first positioning mechanism 24 and the second positioning mechanism 25 include a positioning driver 27 disposed on the carrier plate 22 and a positioning plate 28 mounted on the driving end of the positioning driver 27. The positioning driver 27 is used to drive the positioning plate 28 to move closer to or away from one side of the L-shaped positioning structure 23. Specifically, the positioning driver 27 can be a cylinder.

[0042] In practical applications, when the tray or product is located in the positioning space, the positioning driver 27 drives the positioning plate 28 to translate and push the tray or product until the first positioning mechanism 24, the second positioning mechanism 25 and the L-shaped positioning structure 23 cooperate to position the tray or product.

[0043] In this embodiment, there are multiple first positioning mechanisms 24 and multiple second positioning mechanisms 25. The carrier plate 22 has multiple parallel adjusting transverse grooves 29 and multiple parallel adjusting longitudinal grooves 30. The adjusting transverse grooves 29 are perpendicular to one side of the L-shaped positioning structure 23, and the adjusting longitudinal grooves 30 are perpendicular to the other side of the L-shaped positioning structure 23. The first positioning mechanism 24 can be positioned along the adjusting transverse grooves 29 on the carrier plate 22, and the second positioning mechanism 25 can be positioned along the adjusting longitudinal grooves 30 on the carrier plate 22. In practical applications, the required number of first positioning mechanisms 24 and second positioning mechanisms 25 are used according to the size of the tray or product, and their positions on the carrier plate 22 are adjusted to meet the positioning requirements of trays or products of different sizes.

[0044] In this embodiment, the first positioning mechanism 24 is slidably connected to the carrier plate 22 via the transverse adjustment plate 31, and the second positioning mechanism 25 is slidably connected to the carrier plate 22 via the longitudinal adjustment plate 32. The carrier plate 22 has multiple parallel guide transverse grooves 33 and multiple parallel guide longitudinal grooves 34. The multiple guide transverse grooves 33 are arranged parallel to the multiple adjustment transverse grooves 29, and the multiple guide longitudinal grooves 34 are arranged parallel to the multiple adjustment longitudinal grooves 30, respectively. The transverse adjustment plate 31 has a transverse locking hole 35, and a transverse guide block 36 protrudes from the bottom surface of the transverse adjustment plate 31. The transverse locking hole 35 is used to communicate with the adjustment transverse grooves 29, and the transverse guide block 36 extends into the guide transverse groove 33 and can... The longitudinal adjusting plate 32 is able to slide along the guide groove 33; the longitudinal adjusting plate 32 has a longitudinal locking hole 37, and the bottom surface of the longitudinal adjusting plate 32 has a protruding longitudinal guide block 38. The longitudinal locking hole 37 is used to communicate with the adjusting longitudinal groove 30. The longitudinal guide block 38 extends into the guide longitudinal groove 34 and can slide along the guide longitudinal groove 34; the transverse locking hole 35 is detachably connected to a transverse locking fastener, and the longitudinal locking hole 37 is detachably connected to a longitudinal locking fastener. The transverse locking fastener is used to lock the transverse adjusting plate 31 onto the carrier plate 22, and the longitudinal locking fastener is used to lock the longitudinal adjusting plate 32 onto the carrier plate 22; specifically, the transverse locking hole 35 and the longitudinal locking hole 37 are both threaded holes, and the transverse locking fastener and the longitudinal locking fastener are both locking bolts. In this structural design, when adjusting the position of the first positioning mechanism 24 on the carrier plate 22, the transverse locking fastener is loosened, allowing the transverse guide block 36 on the transverse adjusting plate 31 to move along the guide groove 33 to adjust the position of the first positioning mechanism 24 on the carrier plate 22. After the position adjustment is complete, the transverse locking fastener is tightened to lock the transverse adjusting plate 31 onto the carrier plate 22. Similarly, the position adjustment operation of the second positioning mechanism 25 is the same, and will not be described again here.

[0045] In this embodiment, a feeding chamber 39 and a receiving chamber 40 are arranged side by side on the front side of the machine base 1. The feeding mechanism 2 is located in the feeding chamber 39, and the receiving mechanism 3 is located in the receiving chamber 40. Both the feeding mechanism 2 and the receiving mechanism 3 include a lifting drive device 41 installed on the front side of the machine base 1 and a lifting plate 42 installed on the lifting drive device 41. The lifting plate 42 is lifted and lowered in the feeding chamber 39 or the receiving chamber 40.

[0046] In the feeding mechanism 2, multiple products are stacked on the lifting pallet 42 or multiple trays loaded with products are stacked on the lifting pallet 42. After the loading and unloading robot 8 removes a product or a tray from the lifting pallet 42, the lifting drive device 41 drives the lifting pallet 42 and the stacked products or trays to rise to a preset height to achieve stable feeding.

[0047] In the receiving mechanism 3, after the loading and unloading robot 8 places a product or a tray on the lifting pallet 42, the lifting drive device 41 drives the lifting pallet 42 to descend a preset height along with the stacked products or trays to achieve stable receiving.

[0048] In this embodiment, the dual-platform barcode scanner also includes a conveyor 43; specifically, the conveyor 43 can be a handcart or an AGV trolley, and a conveyor 43 can be moved into both the feeding chamber 39 and the receiving chamber 40; the top surface of the conveyor 43 is provided with a stacking bin 44, and the lifting pallet 42 can extend into the stacking bin 44.

[0049] In the feeding mechanism 2, the conveyor 43 transports the stacked products or trays to the feeding chamber 39. At this time, the lifting pallet 42 is located below the stacked products or trays. When the lifting pallet 42 is raised, the products or trays in the stacking bin 44 can be lifted. When the conveyor 43 is unloaded, the unloaded conveyor 43 can be moved into the receiving chamber 40.

[0050] In the receiving mechanism 3, the empty conveyor 43 moves into the receiving chamber 40. At this time, the lifting pallet 42 is located at the top of the stacking bin 44. The loading and unloading robot 8 picks up the scanned products or trays and stacks them in the stacking bin 44. The lifting pallet 42 supports the products or trays stacked in the stacking bin 44. For each product or tray stacked in the stacking bin 44, the lifting pallet 42 will descend a preset height until the stacked products or trays are placed on the conveyor 43. When the conveyor 43 is fully loaded, the fully loaded conveyor 43 can be moved out of the receiving chamber 40.

[0051] In this embodiment, the stacking bin 44 includes a base plate 45 disposed on the top surface of the conveyor 43 and a plurality of columns 46 disposed on the base plate 45. The plurality of columns 46 surround a stacking space. There is an insertion space 47 between the base plate 45 and the top surface of the conveyor 43, into which a lifting pallet 42 can be inserted. The position of the columns 46 on the base plate 45 is adjustable, and the base plate 45 can be raised and lowered along the columns 46.

[0052] In practical applications, after the conveyor 43 moves into the feeding chamber 39 or the receiving chamber 40, the lifting pallet 42 is inserted into the insertion space 47, and the lifting pallet 42 can lift and lower the base plate 45. In addition, the position of the column 46 on the base plate 45 can be adjusted according to different product or tray specifications to change the size of the stacking space.

[0053] In this embodiment, the top surface of the conveyor 43 is provided with a frame 48, the stacking bin 44 is located inside the frame 48, and a push handle 59 is provided on the front side of the frame 48. The push handle 59 is provided to facilitate workers to push the conveyor 43 by hand.

[0054] In this embodiment, guide plates 49 are installed on both opposite sidewalls of the feeding chamber 39 and both opposite sidewalls of the receiving chamber 40. Multiple guide wheels 50 are rotatably connected to the guide plates 49 in a straight line. The guide wheels 50 are used to roll against the sides of the frame 48. When the conveyor 43 enters the feeding chamber 39 or the receiving chamber 40, the two sidewalls of the frame 48 on the conveyor 43 roll against the guide wheels 50 on the two guide plates 49, allowing the conveyor 43 to move smoothly and stably into or out of the feeding chamber 39 or the receiving chamber 40.

[0055] In this embodiment, a locking ring 51 is provided on the rear side of the conveyor 43. The inner sidewalls of the feeding chamber 39 and the receiving chamber 40 are provided with a trigger switch 52, a limit block 53, a telescopic driver 54, and a locking tongue 55 installed on the telescopic end of the telescopic driver 54. The telescopic driver 54 is used to drive the locking tongue 55 to extend and retract. The locking tongue 55 can be inserted into the inner hole of the locking ring 51. The side of the locking ring 51 is used to abut the trigger switch 52, and the limit block 53 is used to abut the conveyor 43. The trigger switch 52 can be a limit sensor. The trigger switch 52 is electrically connected to the telescopic driver 54. The telescopic driver 54 can be a cylinder.

[0056] When the conveyor 43 moves into the feeding chamber 39 or the receiving chamber 40 and is in position, the conveyor 43 abuts against the limiting block 53 and is limited. The locking ring 51 of the conveyor 43 abuts against the trigger switch 52. The trigger switch 52 sends a signal to the telescopic actuator 54, causing the telescopic actuator 54 to drive the locking tongue 55 to extend, thereby inserting the locking tongue 55 into the inner hole of the locking ring 51 to lock the conveyor 43 in the feeding chamber 39 or the receiving chamber 40. When it is necessary to move the conveyor 43 out of the feeding chamber 39 or the receiving chamber 40, the telescopic actuator 54 drives the locking tongue 55 to retract, causing the locking tongue 55 to move out of the locking ring 51 to unlock the conveyor 43.

[0057] Specifically, the top surface of the machine base 1 is equipped with a housing 57, and the front and rear panels of the housing 57 are equipped with control panels 58. The machine base 1 is equipped with a main unit, which is electrically connected to the two control panels 58. The two control panels 58 are connected to each other, which makes it easier for operators to control and adjust the machine, and reduces the need for operators to frequently walk back and forth between the front and rear panels of the housing 57 in order to control the control panels 58.

[0058] All technical features in this embodiment can be freely combined according to actual needs.

[0059] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
