[0030] 100. Material tray. DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0032] The present invention relates to an improvement of labeling equipment for SMT trays. The improved universal labeling line, through the setting of a first camera component and a sensing component, enables a control unit to obtain in advance the size parameters, thickness parameters and original barcode position of the tray before the tray passes through the code reading component, so that the control unit can control the operating conditions of the code reading component, the labeling component and the verification component according to the size parameters, thickness parameters and original barcode position of the tray, so that trays with different sizes, thicknesses and barcode positions can be put on line for labeling at the same time, the equipment has better versatility, saves operating costs and improves labeling efficiency.

[0033] See also Figure 1 As shown, a universal labeling line for SMT trays is shown, which includes a frame 1, a loading mechanism, a labeling mechanism and a unloading mechanism arranged in sequence from one end to the other end of the frame 1, and a control unit arranged on the frame 1. In this example, the control unit is a PLC system installed inside the frame 1.

[0034] like Figure 2 and Figure 3 As shown, the labeling mechanism includes: a first conveyor belt 2 for conveying a material tray 100, a barcode reading component 3 for picking up the original barcode on the material tray 100, a marking component 4 for printing labels, a labeling component 5 for pasting labels, and a verification component 6, which are located on one side of the first conveyor belt 2 and arranged in sequence along the conveying direction of the first conveyor belt 2. The material tray 100 can pass through the barcode reading component 3, the marking component 4, the labeling component 5, and the verification component 6 in sequence. The first conveyor belt 2 is driven by a built-in motor, and includes two pulleys and a transmission belt connected to the two pulleys, and is installed on the frame 1 through a bracket.

[0035] The innovation of this example is: Figure 2As shown, the labeling mechanism also includes a first camera component 7 located on the conveying path of the material tray 100 for obtaining the size parameters of the material tray 100 and the original barcode position, and a sensing component 8 for obtaining the thickness parameters of the material tray 100. The control unit can adjust the operating conditions of the code reading component 3, the labeling component 5 and the review component 6 according to the size parameters and / or the original barcode position and / or the thickness parameters. In this way, before the material tray 100 starts to be labeled, the first camera component 7 first captures the overall image of the material tray 100, and the overall image is transmitted to the PLC system. The PLC system can obtain the size parameters and the original barcode position of the material tray 100 based on the image, and then obtain the thickness parameters of the material tray 100 through the sensing component 8 and transmit it to the PLC system. The PLC system stores multiple sets of operating plans corresponding to different size parameters, original barcode positions and thickness parameters. The PLC system can select a suitable operating plan based on the specific size parameters, original barcode positions and thickness parameters of the material tray 100, and control the rear code reading component 3, labeling component 5 and review component 6 to move to the corresponding positions according to the operating plan, so that multiple different types of material trays 100 can be labeled online at the same time.

[0036] Among them, the first camera assembly 7 is located between the feeding mechanism and the labeling mechanism, and includes a first bracket 7a, a first camera 7b arranged on the first bracket 7a, and two first light sources 7c arranged on the first bracket 7a and respectively located on both sides of the first camera 7b. The sensing component 8 is located on the first conveyor belt 2 at the front end of the code reading component 3, and includes a second bracket 8a and a displacement sensor 8b arranged on the top of the second bracket 8a. The material tray 100 can cooperate to pass through the first bracket 7a and the second bracket 8a in sequence and pass under the first camera 7b and the displacement sensor 8b. The first bracket 8a and the second bracket 7a in this example are both door-type brackets fixed on the frame 1, and the material tray 100 can pass through the door-type bracket.

[0037] In this embodiment, if Figure 2-3 As shown, the barcode reading assembly 3 includes a rotatable first manipulator 3a and a second camera assembly 3b which is installed on the first manipulator 3a and can be lifted. The second camera assembly 3b can pass over the material tray 100 and capture the original barcode image. Here, the control unit controls the movement of the first manipulator 3a according to the obtained barcode position information, so that the second camera assembly 3b can accurately find the barcode position and take pictures, thereby ensuring the barcode reading efficiency; the photographed barcode image can be transmitted back to the control unit, and the control unit can obtain the corresponding barcode information according to the barcode image.

[0038] The labeling component 5 includes a rotatable second manipulator 5a and a labeling head 5b installed on the second manipulator 5a. The labeling head 5b can cooperate to suck the label and paste the label on the material tray 100. Here, the labeling head 5b is a pneumatic suction cup, and the labeling head 5b sucks the label by passing compressed air. The labeling component 4 is a printer, which prints out the corresponding label according to the barcode information obtained by the control unit, and then the control unit controls the movement of the second manipulator 5a according to the obtained barcode position information and accurately pastes the label on the corresponding position of the material tray 100.

[0039] Furthermore, if Figure 4 As shown, the labeling head 5b includes a connecting plate 5b1 connected to the second manipulator 5a, a label suction plate 5b2 parallel to the connecting plate 5b1, and a spring 5b3 located between the connecting plate 5b1 and the label suction plate 5b2. In this way, when the label suction head 5b absorbs the label, the spring can provide appropriate buffering to avoid damaging the label.

[0040] The review component 6 includes a rotatable third manipulator 6a and a third camera component 6b installed on the third manipulator 6a. The third camera component 6b can pass over the tray 100 and capture the image of the label. After the third camera component 6b captures the image of the label, the control unit compares the label image with the label information stored inside it to determine whether the label posting position and the corresponding information on the label are accurate. If the review is successful, the tray 100 will be sent to the next area. If the review fails, the equipment will alarm and stop.

[0041] In this embodiment, if Figure 5 As shown, the second camera assembly 3b and the third camera assembly 6b respectively include a third bracket 20, a second camera 21 disposed on the third bracket 20, and two second light sources 22 disposed on the third bracket 20 and respectively located on both sides and below the second camera 21. The first camera 7b and the second camera 21 are both CDD cameras.

[0042] like Figure 7 As shown, the feeding mechanism and the unloading mechanism respectively include a conveying assembly 9 arranged on the frame 1 and two lifting assemblies 10 respectively arranged at both ends of the conveying assembly 9. The first camera assembly 7 is installed above the lifting assembly 10 at the rear end of the feeding mechanism.

[0043] The conveying assembly 9 includes a second conveyor belt 9a and a third conveyor belt 9b arranged vertically, the second conveyor belt 9a and the third conveyor belt 9b are parallel to each other and convey in opposite directions; the lifting assembly 10 includes a base 10a, a fourth conveyor belt 10b which is arranged on the base 10a and can be lifted, and a first driving module 10c for driving the fourth conveyor belt 10b to lift. Among them, the fourth conveyor belt 10b is parallel to the second conveyor belt 9a and the third conveyor belt 9b, and the fourth conveyor belt 10b can be on the same horizontal plane as the second conveyor belt 9a and the third conveyor belt 9b at the two end points of its lifting stroke, and the loading mechanism and the unloading mechanism also respectively include a plurality of carriers 11 for loading the material tray 100 which are movably arranged on the second conveyor belt 9a, the third conveyor belt 9b and the fourth conveyor belt 10b.

[0044] In this example, the second conveyor belt 9a, the third conveyor belt 9b and the fourth conveyor belt 10b respectively include two conveyor belt monomers parallel to each other, each conveyor belt monomer includes two pulleys and a first belt drivingly connected to the two pulleys, and the two sides of the carrier 11 can be mounted on the two conveyor belt monomers in a coordinated manner. Preferably, the outer side of the first belt has a limit plate extending upward for supporting the carrier 11.

[0045] Furthermore, the conveying assembly 9 also includes a driving shaft 9c respectively inserted into two corresponding pulleys in the second conveyor belt 9a and the third conveyor belt 9b, a first gear 9d sleeved on the end of the driving shaft 9c, a first motor 9e for driving the second conveyor belt 9a and the third conveyor belt 9b, and a second gear 9f sleeved on the output shaft of the first motor 9e. The first gear 9d and the second gear 9f are connected by a second belt. In this way, the operation of the second conveyor belt 9a and the third conveyor belt 9b can be realized by the cooperation of the first gear 9d and the second gear 9f. The fourth conveyor belt 10b is driven and operated by a built-in motor.

[0046] Furthermore, the first driving module 10c includes a servo motor 10c1, a screw rod 10c2 coaxially connected to the output shaft of the servo motor 10c1, and the screw rod 10c2 is arranged along the up-down direction. A slider 10b1 is connected to one end of the fourth conveyor belt 10b, and the slider 10b1 is threadedly connected to the screw rod 10c2. When the screw rod 10c2 rotates, the slider 10b1 can move along the length direction of the screw rod 10c2. By using the servo motor 10c1 to drive the screw rod 10c2, the lifting and lowering of the fourth conveyor belt 10b can be paused. When loading, the fourth conveyor belt 10b stops lifting and lowering. Every time a material tray 100 is taken away, the fourth conveyor belt 10b rises one position, which is convenient for the next grabbing and reduces the material taking stroke; when unloading, the fourth conveyor belt 10b also stops lifting and lowering. Every time a material tray 100 is put down, the fourth conveyor belt 10b drops one position, so that when unloading, there is no need to constantly change the stroke with the stacking height of the material tray 100, thereby improving the unloading efficiency.

[0047] In this example, the screw rod 10c2 is built into a linear rail, and the slider 10b1 is slidably disposed on the linear rail.

[0048] Furthermore, the lifting assembly 10 also includes two guide rods 10d connected to the lower part of the fourth conveyor belt 10b and extending downward. The two guide rods 10d are movably arranged in the base 10a along their axial direction for guiding when the fourth conveyor belt 10b is lifted or lowered.

[0049] Furthermore, the loading mechanism and the unloading mechanism also respectively include a plurality of limit bars 23 provided on the frame 1 and respectively located on both sides of the second conveyor belt 9a and the third conveyor belt 9b. The limit bars 23 are arranged along the up and down directions and can respectively cooperate to block the material trays 100 on the second conveyor belt 9a and the third conveyor belt 9b to prevent the material trays 100 from falling.

[0050] In this embodiment, if Figure 6 As shown, the loading mechanism also includes a rotatable fourth manipulator 12 and a loading head 13 installed on the fourth manipulator 12. The loading head 13 can cooperate to suck the material tray 100 and move the material tray 100 from the fourth conveyor belt 10b to the front end of the first conveyor belt 2. The loading head 13 here is also a pneumatic suction cup. The specific principle is not repeated. It can suck the material tray 100 to be labeled to the first conveyor belt 2 to realize the loading of the material tray 100.

[0051] In this embodiment, the first manipulator 3a, the second manipulator 5a, the third manipulator 6a and the fourth manipulator 12 respectively include a support 24, a rotating plate 25 rotatable at one end on the support 24 around the vertical direction, a manipulator body 26 rotatable at the other end of the rotating plate 25 around the vertical direction, and a telescopic rod 27 telescopically arranged at the lower part of the manipulator body 26 along the up-down direction. The second camera assembly 3b, the label suction head 5b, the third camera assembly 6b and the loading head 13 are all connected to the telescopic rod 27. The three-axis motion of the manipulator is realized by the cooperation of the rotating plate 25, the manipulator body 26 and the telescopic rod 27, so as to ensure the normal operation of the code reading, labeling and review processes.

[0052] like Figure 2-3 As shown, the unloading mechanism further includes an unloading head 14 capable of moving in the horizontal direction and the vertical direction respectively for sucking the material tray 100 and moving the material tray 100 from the first conveyor belt 2 to the fourth conveyor belt 10b, and a second driving module 15 for driving the unloading head 14 to move. The unloading head 14 here is also a pneumatic suction cup, which can send the labeled material tray away from the first conveyor belt 2.

[0053] In this example, the driving module 15 is a dual-axis mechanism, which includes a linear rail 15a with a built-in screw extending along the conveying direction of the conveyor belt 2, a second motor 15b for driving the screw to rotate, a slide 15c slidably arranged on the linear rail 15a, and a cylinder for driving the slide 15c to slide. The unloading head 14 is slidably arranged on the slide 15c along the up and down directions.

[0054] As a preferred solution, the loading mechanism and the unloading mechanism further include a guiding unit, which includes a plurality of rotating shafts 16 arranged along the up-down direction and rotatable at each end of the base 10a, a third driving module 17 for driving the plurality of rotating shafts 16 to rotate, a guiding rod 18 parallel to each rotating shaft 16, and a connecting rod 19 connected to the rotating shaft 16 and the guiding rod 18 at both ends, wherein the carrier 11 can be accommodated between the plurality of rotating shafts 16, and the rotation directions of each two adjacent rotating shafts 16 are opposite, and the plurality of guiding rods 18 can be relatively retracted and surround the material tray 100 against the center of the carrier 11. In this way, the material tray 100 can always be located at the center of the carrier 11, which is convenient for the robot to grasp. Among them, the third driving module 17 is a combination of a motor and a synchronous belt, which can drive the plurality of rotating shafts 16 to rotate synchronously, and the fourth driving module 17 is purchased from outside, and the specific principle is not repeated.

[0055] In this embodiment, in the loading assembly, the lifting assemblies 10 at both ends of the conveying assembly 9 include a first lifting assembly at the front end for manual material discharge and a second lifting assembly at the rear end for material loading. In the unloading assembly, the lifting assemblies 10 at both ends of the conveying assembly 9 include a first lifting assembly at the front end for unloading and a second lifting assembly at the rear end for manual material collection.

[0056] Specifically, when loading, the first lifting assembly in the loading mechanism and the fourth conveyor belt 10b in the second lifting assembly are both lowered to be parallel to the third conveyor belt 9b. At this time, the material tray 100 can be placed on the carrier 11 on the fourth conveyor belt 10b in the first lifting assembly. The carrier 11 is driven by the fourth conveyor belt 10b in the first lifting assembly to move to the third conveyor belt 9b, and then moves from the third conveyor belt 9b to the fourth conveyor belt 10b in the second lifting assembly. Finally, the fourth conveyor belt 10b in the second lifting assembly rises and cooperates with the fourth manipulator 12 to clamp, so as to realize loading. After loading is completed, the fourth conveyor belt 10b in the second lifting assembly rises to be parallel to the second conveyor belt 9a, and the empty carrier 11 can move from the fourth conveyor belt 10b in the second lifting assembly to the second conveyor belt 9a. At this time, the fourth conveyor belt 10b in the first lifting assembly rises to be parallel to the second conveyor belt 9a, and the carrier 11 on the second conveyor belt 9a can return to the fourth conveyor belt 10b in the first lifting assembly. Finally, the fourth conveyor belt 10b in the first lifting assembly descends to be parallel to the third conveyor belt 9b. At this time, the material tray 100 can be put in again to realize the cycle.

[0057] When unloading, the fourth conveyor belt 10b in the first lifting assembly rises to a position parallel to the second conveyor belt 9a. At this time, the unloading head 14 grabs the material tray 100 at the end of the first conveyor belt 2 and places it on the carrier 11 on the fourth conveyor belt 10b in the first lifting assembly. The fourth conveyor belt 10b in the first lifting assembly gradually descends with the stacking of the material trays 100. When the fourth conveyor belt 10b in the first lifting assembly descends to a position parallel to the third conveyor belt 9b, unloading stops. Subsequently, the carrier 11 carrying multiple material trays 100 moves from the fourth conveyor belt 10b in the first lifting assembly to the third conveyor belt 9b. At this time, the fourth conveyor belt 10b in the second lifting assembly descends to a position parallel to the third conveyor belt 9b. , the carrier 11 can move from the third conveyor belt 9b to the fourth conveyor belt 10b in the second lifting assembly, and then the worker can complete the material collection; after the material collection is completed, the fourth conveyor belt 10b in the second lifting assembly rises to a position parallel to the second conveyor belt 9a, and the empty carrier 11 moves from the fourth conveyor belt 10b in the second lifting assembly to the second conveyor belt 9a. At this time, the fourth conveyor belt 10b of the first lifting assembly rises to a position parallel to the second conveyor belt 9a, and then the carrier 11 can return from the second conveyor belt 9b to the fourth conveyor belt 10b in the first lifting assembly. At this time, the unloading head 14 can grab the previous material tray 100 again and lower it to the fourth conveyor belt 10b in the first lifting assembly to realize the cycle.
