Description

Technical Field

[0001] The invention belongs to the technical field of learning machine production equipment, and specifically relates to a parts transfer device for learning machine production. Background Art

[0002] Learning machines usually refer to an electronic device or educational tool that is specially designed to assist learning and education. They usually have specific software or applications that can provide various educational content, such as learning courses, exercises, teaching videos, etc. Learning machines can be portable devices, such as tablets, e-book readers or specific educational toys, or desktop devices, such as computers or smart electronic whiteboards. Tablet learning machines are one of them. The parts of this learning machine include electronic components, display screens, batteries, circuit boards, and casings. When these parts are produced, they need to be transported through some transfer devices to facilitate automated production and improve production efficiency.

[0003] After the existing tablet learning machine shell is produced, it needs to be transported to different inspection areas for quality inspection through a transfer device. However, after the tablet learning machine shell is punched, there may be some burrs on the outside and inside. However, the existing transfer device is relatively simple in design, and simply transfers the shell with burrs to the designated area, but does not distinguish whether it is the front or the back. A secondary inspection and transfer is required in the designated area, which improves the process of the entire production line and thereby reduces the production efficiency of the learning machine shell. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a parts transfer device for the production of a learning machine.

[0006] Furthermore, the flipping mechanism includes two first fixed frames arranged on one side of the first conveying roller assembly, and a rotating shaft is rotatably connected between the two first fixed frames. Two flipping disks are fixedly connected to the outer wall of the rotating shaft, and a plurality of evenly distributed grooves are opened on the two flipping disks. A first motor is fixedly installed at the rear end of one of the first fixed frames, and the front end of the output shaft of the first motor is fixedly connected to the rear end of the rotating shaft.

[0007] Through the above technical solution, after the front side of the flat-panel learning machine shell is inspected, it needs to be turned over for back side inspection. At this time, when the flat-panel learning machine shell is transported to the slots in the two flip disks by the first conveying roller assembly, the first motor is started. The first motor drives the rotating shaft to rotate through intermittent rotation of the output shaft. The rotation of the rotating shaft drives the two flip disks to rotate, and then drives the flat-panel learning machine shells in multiple slots to rotate. When the two flip disks continue to rotate intermittently, multiple flat-panel learning machine shells are turned over to the second conveying roller assembly and transported one after another, so that the subsequent inspection mechanism can perform back side inspection on them.

[0008] Furthermore, the detection mechanism includes a fixed frame fixedly connected to the top of the first conveying roller assembly or the second conveying roller assembly, two light strips are fixedly connected to the fixed frame, two cameras are fixedly connected to the fixed frame and located in the middle of the two light strips, the top of the first conveying roller assembly or the second conveying roller assembly is fixedly connected to a support seat, the top of the support seat is installed with a display device, and wires are fixedly connected between the display device and the two cameras.

[0009] Through the above technical scheme, when the tablet learning machine shell is conveyed on the first conveyor roller assembly, two light strips are illuminated, and two cameras take pictures and detect the front side of the tablet learning machine. The pictures are saved in the display device. The staff can observe through the display device, detect the tablet learning machine shell with burrs and transmit the information to the coding mechanism, and the coding mechanism will code the tablet learning machine shell with burrs.

[0011] Through the above technical scheme, since the detection mechanism and the code sticking mechanism on the first conveying roller assembly are closely connected, after the flat-panel learning machine shell is detected by the detection mechanism for burrs and is conveyed to the bottom of the first mounting frame through the first conveying roller assembly, the second motor is started, so that the second motor drives the main shaft to rotate, and drives the secondary shaft to rotate through the connected pulley and synchronous belt, and then drives the connecting rod frame to swing, so that the connecting rod frame drives the suction cup to swing to the QR code winding strip. At this time, the air pump is started, so that the air pump draws air to the suction cup through the connecting pipe, so that the suction cup absorbs the QR code patch on the QR code winding strip, and then drives the QR code patch to be attached to the front of the flat-panel learning machine shell by swinging back through the connecting rod frame. At the same time, the third motor is driven, so that the winding assembly continues to wind the QR code winding strip, and the reciprocating swing of the connecting rod frame drives the suction cup to stick the code. Similarly, the code sticking mechanism on the second conveying roller assembly sticks the code on the back of the flat-panel learning machine shell.

[0014] Furthermore, the transfer mechanism includes a transfer frame arranged at the rear end of one side of the second conveying roller assembly, the center of the transfer frame is fixedly connected with a fixed bar, the front ends of the fixed bar are rotatably connected with a driving shaft and a driven shaft respectively, the outer walls of the driving shaft and the driven shaft are fixedly connected with sprockets, a chain is meshed between the two sprockets, a movable block is fixedly connected to the chain, a plurality of transfer bars are fixedly connected to the front end of the movable block, a limiting frame is slidably connected to the transfer frame, the movable block slides in the limiting frame, a fourth motor is fixedly installed on the bottom of the rear end of the fixed bar, and the front end of the output shaft of the fourth motor is fixedly connected to the rear end of the driving shaft.

[0015] Through the above technical solution, when the second conveying roller assembly transports the flat-panel learning machine shell to one end, the fourth motor drives the driving shaft to rotate, and the driving shaft drives the connected sprocket to rotate, and cooperates with another sprocket to drive the chain to rotate, thereby driving the movable block and multiple transfer bars to rotate. When the movable block rotates, it drives the limit frame to slide on the transfer frame, and the limit frame limits the movable block, thereby improving the stability of the movable block during transmission, thereby improving the stability of the flat-panel learning machine shell during transportation, and transferring it to the distribution mechanism through the chain.

[0016] Furthermore, the transport mechanism includes a third conveyor roller assembly arranged on one side of the second conveyor roller assembly, a fourth conveyor roller assembly is fixedly installed on the top of the third conveyor roller assembly, and a fifth conveyor roller assembly is fixedly installed on the top of the fourth conveyor roller assembly.

The produced flat-panel learning machine shells are transferred in quality without the need for secondary transfer, which is not only efficient but also greatly reduces the transfer cost.

[0018] Furthermore, the transport distribution mechanism includes a second fixed frame arranged on one side of the front end of the third conveying roller assembly, the front end of the second fixed frame is rotatably connected to a plurality of connecting shafts, the rear ends of the outer walls of the plurality of connecting shafts are respectively fixedly connected to the first transport distribution frame, the second transport distribution frame, and the third transport distribution frame, the first transport distribution frame is located on one side of the third conveying roller assembly, the second transport distribution frame is located on one side of the fourth conveying roller assembly, and the third transport distribution frame is located on one side of the fifth conveying roller assembly, the other side of the front end of the second fixed frame is fixedly connected to a plurality of fixed seats, electric push rods are fixedly installed on the plurality of fixed seats, one end of the piston rods of the plurality of electric push rods are fixedly connected to racks, the front ends of the outer walls of the plurality of connecting shafts are fixedly connected to gears, the plurality of gears are respectively meshed with corresponding racks, the front end of the second fixed frame is fixedly connected to a concave seat close to the corresponding rack, and the plurality of racks are respectively slidably connected to the corresponding concave seats.

[0019] Through the above technical solution, when the first barcode scanner scans the QR code patch on the front side of the flat-panel learning machine shell, and the second barcode scanner does not scan the QR code patch on the back side of the flat-panel learning machine shell, the electric push rod associated with the first sub-transport rack is started, so that the electric push rod pushes the rack, so that the rack slides in the concave seat to push the gear, so that the gear drives the connected connecting shaft to rotate, and drives the first sub-transport rack to rotate 90 degrees, so that the first sub-transport rack is flush with the third conveyor roller assembly. At this time, the movable block and multiple transfer bars drive the flat-panel learning machine shell to be transferred.

When the QR code patches on the front and back of the flat-panel learning machine shell are scanned by the first barcode scanner and the second barcode scanner respectively, it is transferred to the fifth conveyor roller assembly through the third sub-transport rack in the same way. The flat-panel learning machine shell with burrs is transferred in an orderly manner, and the whole transfer process is relatively intelligent, without the need for subsequent inspection and transfer, which reduces the transfer process of the entire production line and thus improves production efficiency.

[0020] Furthermore, the pushing mechanism includes a third fixed frame arranged between the second conveying roller assembly and the second fixed frame, and multiple groups of cylinders are fixedly installed on the third fixed frame, and one end of the multiple groups of cylinder pistons are respectively fixedly connected to the first push plate, the second push plate and the third push plate, the first push plate is close to the first sub-transport frame, the second push plate is close to the second sub-transport frame, and the third push plate is close to the third sub-transport frame.

[0021] Through the above technical scheme, when the flat-panel learning machine shell is transferred to the first transport rack, a group of cylinders associated with the first push plate are started at this time, and the first push plate is driven to move by a group of cylinder pistons, thereby pushing the flat-panel learning machine shell on the first transport rack, so that the flat-panel learning machine shell moves to the third conveying roller assembly. When the flat-panel learning machine shell is transferred to the second transport rack, it is pushed to the fourth conveying roller assembly by the second push plate. When the flat-panel learning machine shell is transferred to the third transport rack, it is pushed to the fifth conveying roller assembly by the third push plate, thereby realizing the transfer and transportation of flat-panel learning machine shells of different qualities.

When the first barcode scanner 602 scans the QR code patch on the front side of the tablet learning machine housing 12, and the second barcode scanner 604 does not scan the QR code patch on the back side of the tablet learning machine housing 12, the first distribution rack 1003 is associated with the start The electric push rod 1007 makes the electric push rod 1007 push the rack 1008, so that the rack 1008 slides in the concave seat 1010 and pushes the gear 1009, so that the gear 1009 drives the connected connecting shaft 1002 to rotate, and drives the first sub-transport frame 1003 to rotate 90 degrees, so that the first sub-transport frame 1003 and the third conveyor roller assembly 901 remain flush, at this time the movable block 807 and the plurality of transfer bars 808 drive the flat-panel learning machine housing 12 for transfer, and the plurality of transfer bars 808 move downward and penetrate the first sub-transport frame 1003, and transfer the flat-panel learning machine housing 12 to the first sub-transport frame 1003, and then push it to the third conveyor roller assembly 901 through the subsequent pushing mechanism 11 for transportation to the designated area, and the electric push rod 1 after transportation 007 reset drives the first transport rack 1003 to reset. When the first barcode scanner 602 scans the QR code patch on the back of the tablet learning machine housing 12, and the second barcode scanner 604 does not scan the QR code patch on the front of the tablet learning machine housing 12, it is transferred to the fourth conveyor roller assembly 902 through the second transport rack 1004 in the same way. When the QR code patches on the front and back of the tablet learning machine housing 12 are scanned by the first barcode scanner 602 and the second barcode scanner 604 respectively, they are transferred to the fifth conveyor roller assembly 903 through the third transport rack 1005 in the same way, and the tablet learning machine housing 12 with burrs is transferred in an orderly manner. The whole transfer process is relatively intelligent, and there is no need for subsequent inspection and transfer, which reduces the transfer process of the entire production line.This improves production efficiency.

[0033] like Figure 1-10 As shown, a pushing mechanism 11 is provided at the front end center of the transfer mechanism 8, and the pushing mechanism 11 includes a third fixed frame 1101 arranged between the second conveying roller assembly 3 and the second fixed frame 1001, and multiple groups of cylinders 1102 are fixedly installed on the third fixed frame 1101, and one end of the pistons of the multiple groups of cylinders 1102 are respectively fixedly connected with a first push plate 1103, a second push plate 1104 and a third push plate 1105, the first push plate 1103 is close to the first sub-transport frame 1003, the second push plate 1104 is close to the second sub-transport frame 1004, and the third push plate 1105 is close to the third sub-transport frame 1005. When the flat-panel learning machine housing 12 is transferred to the first sub-transport frame 1003, the first push plate 1103 is started at this time. A group of cylinders 1102 associated with the plate 1103, through the push of a group of cylinder 1102 pistons, drives the first push plate 1103 to move, and then pushes the flat-panel learning machine housing 12 on the first transport rack 1003, so that the flat-panel learning machine housing 12 moves to the third conveying roller assembly 901. When the flat-panel learning machine housing 12 is transferred to the second transport rack 1004, it is pushed to the fourth conveying roller assembly 902 through the second push plate 1104. When the flat-panel learning machine housing 12 is transferred to the third transport rack 1005, it is pushed to the fifth conveying roller assembly 903 through the third push plate 1105, thereby realizing the transfer and transportation of flat-panel learning machine housings 12 of different qualities.

[0034] The working principle of this embodiment is as follows: the staff puts several flat-panel learning machine shells 12 onto the first conveying roller assembly 1 with the front side facing up, and the first conveying roller assembly 1 drives several flat-panel learning machine shells 12 to be conveyed. When conveyed to the bottom of the two cameras 403, the two light bars 402 illuminate and shoot the front side through the two cameras 403, and the photographed pictures are saved in the display device 405. The staff can observe through the display device 405, detect the flat-panel learning machine shell 12 with burrs, and transmit the information to the code sticking mechanism 5; The tablet learning machine housing 12 with burrs on the front is transported to the bottom of the first mounting frame 501 through the first conveyor roller assembly 1. After receiving the information, the code sticking mechanism 5 starts the second motor 507, so that the second motor 507 drives the main shaft 502 to rotate, and drives the secondary shaft 503 to rotate through the connected pulley 504 and the synchronous belt 505, thereby driving the connecting rod frame 506 to swing, so that the connecting rod frame 506 drives the suction cup 509 to swing to the two-dimensional code winding strip 514, and then starts the air pump 510. The air pump 510 evacuates the suction cup 509 through the connecting pipe 511, so that the suction cup 509 absorbs the two-dimensional code patch on the two-dimensional code winding strip 514, and then swings back through the connecting rod frame 506 to drive the two-dimensional code patch to be attached to the front of the flat-panel learning machine housing 12, and at the same time drives the third motor 515 to make the winding component 513 continue to wind the two-dimensional code winding strip 514, and the connecting rod frame 506 swings back and forth to drive the suction cup 509 to attach the code, so as to achieve the attachment of the code to the flat-panel learning machine housing 12 with burrs on the front; The flat-panel learning machine housing 12 continues to be transported by the first conveying roller assembly 1. When it is transported to the slots 204 in the two flip disks 203, the first motor 205 is started. The first motor 205 drives the rotating shaft 202 to rotate through the intermittent rotation of the output shaft. The rotation of the rotating shaft 202 drives the two flip disks 203 to rotate, thereby driving the flat-panel learning machine housings 12 in the multiple slots 204 to rotate. When the two flip disks 203 continue to rotate intermittently, the multiple flat-panel learning machine housings 12 are flipped onto the second conveying roller assembly 3; The flipped flat-panel learning machine housing 12 is conveyed by the second conveying roller assembly 3. Similarly, the back side of the flat-panel learning machine housing 12 is inspected by the detection mechanism 4 on the second conveying roller assembly 3. Similarly, the flat-panel learning machine housing 12 with burrs on the back side is labeled by the code sticking mechanism 5 on the second conveying roller assembly 3. The tablet learning machine housing 12 continues to be transported by the second conveying roller assembly 3. When it is transported to the center of the code scanning mechanism 6, the first code scanner 602 scans the QR code patch on the front of the tablet learning machine housing 12, and the second code scanner 604 scans the QR code patch on the back of the tablet learning machine housing 12, and transmits three types of information, namely, the tablet learning machine housing 12 has a QR code on the front and no code on the back, has no code on the front and has a QR code on the back, and has a QR code on both the front and back sides, to the distribution mechanism 10; The flat learning machine housing 12 continues to be transported by the second conveying roller assembly 3. When it is transported to one end of the second conveying roller assembly 3, the fourth motor 810 drives the driving shaft 803 to rotate. The driving shaft 803 rotates to drive the connected sprocket 805 to rotate, and cooperates with another sprocket 805 to drive the chain 806 to rotate, thereby driving the movable block 807 and the plurality of transfer bars 808 to rotate, thereby driving the flat learning machine housing 12 to be transferred to the distribution mechanism 10; After receiving the information that there is a QR code on the front of the learning machine housing 12 and no code on the back, the transport mechanism 10 starts the electric push rod 1007 associated with the first transport frame 1003, so that the electric push rod 1007 pushes the rack 1008, so that the rack 1008 slides in the concave seat 1010 and pushes the gear 1009, so that the gear 1009 drives the connected connecting shaft 1002 to rotate, and drives the first transport frame 1003 to rotate 90 degrees, so that the first transport frame 1003 and the third conveyor roller assembly 901 remain flush. At this time, the movable block 807 and multiple transfer bars 808 drive the flat-panel learning machine housing 12 for transfer. When the multiple transfer bars 808 move downward and pass through the first transport frame 1003, and transfer the flat-panel learning machine housing 12 to the first transport frame 1003, a group of cylinders 1102 associated with the first push plate 1103 are started. Through the push of a group of cylinder 1102 pistons, It drives the first push plate 1103 to move, and then pushes the flat-panel learning machine housing 12 on the first transport frame 1003, so that the flat-panel learning machine housing 12 moves to the third conveying roller assembly 901. After the transfer, the electric push rod 1007 resets and drives the first transport frame 1003 to reset. When the transport mechanism 10 receives the information that there is no code on the front of the flat-panel learning machine housing 12 and there is a QR code on the back, the flat-panel learning machine housing 12 is transferred to the fourth conveying roller assembly 902 through the second transport frame 1004 and the second push plate 1104 in a similar manner, and is transported to a designated area. When the transport mechanism 10 receives the information that there is a QR code on both the front and back of the flat-panel learning machine housing 12, the flat-panel learning machine housing 12 is transferred to the fifth conveying roller assembly 903 through the third transport frame 1005 and the third push plate 1105 in a similar manner, and is transported to a designated area, thereby completing the transfer of several flat-panel learning machine housings 12.
