Description

Technical Field

[0001] This utility model relates to the field of assembly line conveyor structures, and in particular to an assembly line conveyor structure with a centering function. Background Technology

[0002] The assembly line conveyor structure is the physical or logical architecture of an assembly line system responsible for the orderly movement of materials, workpieces, or data. In industrial production, it is manifested as physical equipment such as conveyor belts, overhead chains, and AGVs, ensuring that items flow automatically and continuously between workstations. Its core value lies in connecting discrete processes to achieve extremely high efficiency.

[0003] Currently, some conveyor belt structures on production lines require the cartons to be centered when transporting packaged cardboard boxes for subsequent operations. Traditional conveyor belts with centering functions typically use double-headed reverse lead screws paired with servo motors to drive clamps on both sides of the conveyor belt towards the center. The clamps straighten any tilted cartons, and the torque value of the servo motor, along with a controller, allows the clamps to stop and reverse after reaching a certain clamping force. However, some cartons are placed diagonally on the conveyor belt. When the clamps move inward, they come into contact with the diagonal of the cartons, and the servo motor automatically reverses after exceeding the preset torque value. This results in cartons remaining tilted even after passing through the centering structure. Traditional conveyor belt centering structures are inconvenient for monitoring and adjusting the state of such cartons, making the structural design inefficient.

[0004] Therefore, it is necessary to provide a new pipeline conveyor structure with a centering function to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a conveyor system with a centering function that allows for convenient monitoring and adjustment of the status of cartons on the conveyor belt.

[0006] To solve the above-mentioned technical problems, this utility model provides a conveyor belt structure with a centering function, comprising: a conveyor belt structure, a centering positioning structure, and an adjustment structure;

[0007] The conveyor belt structure includes a mounting frame, and the centering positioning structure includes a fixing frame. The fixing frame is located on the upper side of the mounting frame, and its two ends are fixedly connected to the front and rear side wall surfaces of the mounting frame, respectively. Two clamping plates are arranged in a front-to-back distribution on the inner side of the fixing frame. The adjustment structure includes two rotating screws arranged in a front-to-back distribution. The two rotating screws are rotatably connected to the side wall surfaces of the two clamping plates that are relatively far apart. A transverse groove is formed on the surface of the clamping plate located below the rotating screw. A servo motor is fixedly connected to the surface of the clamping plate located on one side of the rotating screw. The output end of the servo motor is fixedly connected to the end of the rotating screw on the adjacent side. A movable part is sleeved on the surface of the rotating screw. An electric telescopic rod is fixedly connected to the surface of the movable part through a connecting plate. An adjusting head is fixedly connected to the telescopic end of the electric telescopic rod. The adjusting head is located on one side of the transverse groove. A visual recognition camera is fixedly connected to the bottom surface of the fixing frame located between the two clamping plates. A photoelectric sensor is fixedly connected to the surface of the mounting frame located next to one side of the clamping plate through a connecting plate.

[0008] As a further embodiment of this utility model, rollers are rotatably connected to both ends of the mounting frame, and the two rollers are driven by a conveyor belt arranged around their outer circumference. The conveyor belt and the rollers are in frictional engagement. A servo motor is fixedly connected to one side wall surface of the mounting frame, and the output end of the servo motor is fixedly connected to the end of one side roller.

[0009] With the above technical solution, when the servo motor is working, it will drive the roller on one side to rotate, and then drive the conveyor belt to move through friction to transport the carton package.

[0010] As a further embodiment of this utility model, a double-headed reverse screw is rotatably connected to the top of the fixing frame. Connecting parts are threaded to both the front and rear sides of the surface of the double-headed reverse screw. The two connecting parts, which are distributed front and rear, are fixedly connected to the clamps on the front and rear sides respectively.

[0011] Through the above technical solution, this device is specifically designed with a centering positioning structure and an adjustment structure to better align the cardboard box and ensure it is placed in the center. During operation, once the package on the conveyor belt has passed the photoelectric sensor for a set time, servo motor one is turned off, and servo motor two is started. The rotation of the double-headed reverse lead screw drives the two connecting parts to move closer together until the two clamping plates clamp the surface of the cardboard box. When the torque value of servo motor two slightly exceeds the set value, the control module drives servo motor two to reverse, causing the two clamping plates to retract. At this point, the visual recognition camera is activated to capture images of the cardboard box. The control module within the structure needs to run an image processing program to receive the images from the visual recognition camera. The system receives images and analyzes the characteristics and positions of the cartons. When it detects that the cartons on the conveyor belt are placed diagonally, the control module activates the servo motor to rotate the lead screw, which in turn moves the movable parts to the appropriate position. The electric telescopic rod is then activated, allowing its adjusting head to pass through the transverse groove and touch the cartons, thus readjusting their angle. The clamping operation described above is then repeated to center and align the cartons a second time. The visual recognition camera is then activated again to take pictures and analyze them until the cartons meet the required status. This structural design gives the centering structure of the conveyor belt excellent status recognition and adjustment capabilities, and the structural design is reasonable.

[0012] As a further embodiment of this utility model, a second servo motor is fixedly connected to the top of the fixed frame, and the output end of the second servo motor is fixedly connected to one end of the double-headed reverse lead screw. A positioning rod is fixedly connected to the top of the fixed frame on both the left and right sides of the double-headed reverse lead screw, and the connecting piece is in sliding fit with the positioning rod.

[0013] Through the above technical solution, by setting a servo motor 2 to drive the double-headed reverse lead screw to rotate, and then in conjunction with the positioning rod 1, the two connecting parts can move synchronously in a direction that is relatively close or relatively far apart.

[0014] As a further embodiment of this utility model, a second positioning rod is fixedly connected to the surface of the clamping plate located on the upper side of the rotating lead screw. The movable part is in sliding engagement with the second positioning rod, and the movable part is in threaded engagement with the rotating lead screw.

[0015] Through the above technical solution, by setting the second positioning rod, the moving part can be limited and move horizontally stably when the rotating screw is rotated under force.

[0016] As a further embodiment of this utility model, a control module is fixedly connected to one side of the surface of the mounting bracket, and the servo motor one, servo motor two, servo motor three, photoelectric sensor, visual recognition camera and electric telescopic rod are all electrically connected to the control module.

[0017] The above technical solution, by setting up a control module, facilitates the control of various electronic components in the structure, thereby enabling the centered placement of the cardboard box.

[0018] Compared with related technologies, the assembly line conveyor structure with a centering function provided by this utility model has the following beneficial effects:

[0019] To ensure proper alignment and centered placement of cardboard boxes, this device features a dedicated centering and adjustment structure. During operation, once the package on the conveyor belt has passed the photoelectric sensor for a set time, servo motor one is deactivated, and servo motor two is activated. The rotation of the double-headed reverse lead screw moves the two connecting parts closer together until the two clamping plates clamp the cardboard box surface. When the torque of servo motor two slightly exceeds the set value, the control module reverses the motor, causing the clamping plates to retract. At this point, a visual recognition camera is activated to capture images of the cardboard box. The control module within the device runs an image processing program to receive the images from the visual recognition camera. The system analyzes the characteristics and positions of the cartons. When it detects that the cartons on the conveyor belt are placed diagonally, the control module starts the servo motor to rotate the lead screw, which in turn moves the movable part to the appropriate position. The electric telescopic rod is then activated, allowing its adjusting head to pass through the transverse groove and touch the cartons, thus readjusting their angle. The clamping operation described above is then repeated to center and straighten the cartons a second time. The visual recognition camera is then activated again to take pictures and analyze them again until the cartons meet the requirements. This structural design gives the centering structure of the conveyor belt good status recognition and adjustment functions, and the structural design is reasonable. Attached Figure Description

[0027] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a conveyor system with a centering function in this utility model. Figure 2 This is a partial structural diagram of a conveyor system with a centering function according to the present invention. Figure 1 ; Figure 3 This is a partial structural diagram of a conveyor system with a centering function according to the present invention. Figure 2 ; Figure 4 This is a partial structural diagram of a conveyor system with a centering function according to the present invention. Figure 3 A pipeline conveyor structure with a centering function includes:

[0028] Conveyor belt structure 1, centering positioning structure 2, and adjustment structure 3;

[0029] The conveyor belt structure 1 includes a mounting frame 4, and the centering positioning structure 2 includes a fixing frame 9. The fixing frame 9 is located on the upper side of the mounting frame 4, and its two ends are fixedly connected to the front and rear side wall surfaces of the mounting frame 4, respectively. Two clamping plates 14 are arranged in a front-to-back distribution on the inner side of the fixing frame 9. The adjustment structure 3 includes two rotating screws 17, which are arranged in a front-to-back distribution. The two rotating screws 17 are rotatably connected to the side wall surfaces of the two clamping plates 14 that are relatively far apart. A transverse groove 15 is formed on the surface of the clamping plate 14 located on the lower side of the rotating screw 17. A servo motor 20 is fixedly connected to the surface of the clamping plate 14. The output end of the servo motor 20 is fixedly connected to the end of the rotating lead screw 17 on the adjacent side. A movable part 21 is sleeved on the surface of the rotating lead screw 17. An electric telescopic rod 19 is fixedly connected to the surface of the movable part 21 through a connecting plate. An adjusting head 18 is fixedly connected to the telescopic end of the electric telescopic rod 19. The adjusting head 18 is located on one side of the transverse groove 15. A visual recognition camera 13 is fixedly connected to the bottom surface of the fixing frame 9 located between the two clamping plates 14. A photoelectric sensor 6 is fixedly connected to the surface of the mounting frame 4 located next to one side of the clamping plate 14 through a connecting plate.

[0030] like Figure 1-4 As shown, rollers are rotatably connected to both ends of the mounting frame 4. The two rollers are driven by a conveyor belt 5 arranged around their outer circumference. The conveyor belt 5 and the rollers are in frictional engagement. A servo motor 7 is fixedly connected to one side wall surface of the mounting frame 4. The output end of the servo motor 7 is fixedly connected to the end of the roller on one side.

[0031] When the servo motor 7 is working, it will drive the roller on one side to rotate, which in turn drives the conveyor belt 5 to rotate through friction to transport the carton package.

[0032] like Figure 1-4 As shown, a double-ended reverse screw 10 is rotatably connected to the top of the fixed frame 9. Connectors are threaded to both the front and rear sides of the surface of the double-ended reverse screw 10. The two connectors, which are distributed front and rear, are fixedly connected to the clamps 14 on the front and rear sides respectively.

[0033] To ensure proper alignment and centered placement of the cardboard box, the device incorporates a centering positioning structure 2 and an adjustment structure 3. During operation, once the package on the conveyor belt 5 has passed the photoelectric sensor 6 for a set time, the servo motor 1 7 is shut off, and the servo motor 2 12 is activated. The rotation of the double-headed reverse lead screw 10 moves the two connecting parts closer together until the two clamping plates 14 clamp the surface of the cardboard box. When the torque value of the servo motor 2 12 slightly exceeds the set value, the control module 8 reverses the servo motor 2 12, causing the two clamping plates 14 to retract. At this point, the visual recognition camera 13 is activated to capture images of the cardboard box. The control module 8 runs an image processing program to receive the images transmitted from the visual recognition camera 13. The system displays the images and analyzes the characteristics and positions of the cartons. When it detects that the cartons on the conveyor belt 5 are placed diagonally, the control module 8 starts the servo motor 20, which drives the rotating screw 17 to rotate, thereby pushing the movable part 21 to adjust to the appropriate position. The electric telescopic rod 19 is then activated, allowing its telescopic end adjustment head 18 to pass through the transverse groove 15 and touch the cartons, thus readjusting the angle of the cartons. After that, the clamping operation of the clamping plate 14 is repeated to center and straighten the cartons a second time. The visual recognition camera 13 is then activated again to take pictures and analyze them again until the state of the cartons meets the requirements. This structural design gives the centering structure of the assembly line conveyor device good state recognition and adjustment functions, and the structural design is reasonable.

[0034] like Figure 1-4 As shown, a servo motor 2 12 is fixedly connected to the top of the fixed frame 9. The output end of the servo motor 2 12 is fixedly connected to one end of the double-headed reverse lead screw 10. Positioning rods 11 are fixedly connected to the top of the fixed frame 9 on both the left and right sides of the double-headed reverse lead screw 10. The connecting parts and the positioning rods 11 are in sliding fit.

[0035] By setting the servo motor 12 to drive the double-headed reverse lead screw 10 to rotate, and then in conjunction with the positioning rod 11, the two connecting parts can move synchronously in a direction that is relatively close or relatively far apart.

[0036] like Figure 1-4 As shown, a positioning rod 16 is fixedly connected to the surface of the clamping plate 14 located on the upper side of the rotating lead screw 17. The movable part 21 is in sliding fit with the positioning rod 16, and the movable part 21 is in threaded fit with the rotating lead screw 17.

[0037] By setting the positioning rod 16, the rotating screw 17 can limit the movement of the movable part 21 and make stable horizontal movement when it is rotated under force.

[0038] like Figure 1-4As shown, a control module 8 is fixedly connected to one side of the surface of the mounting bracket 4. Servo motor 1 7, servo motor 2 12, servo motor 3 20, photoelectric sensor 6, visual recognition camera 13, and electric telescopic rod 19 are all electrically connected to the control module 8.

[0039] By setting up control module 8, it is convenient to control the various electronic components in the structure to achieve the centering of the cardboard box.

[0040] The working principle of the assembly line conveyor structure with a centering function provided by this utility model is as follows:

[0041] To ensure proper alignment and centered placement of the cardboard box, the device incorporates a centering positioning structure 2 and an adjustment structure 3. During operation, once the package on the conveyor belt 5 has passed the photoelectric sensor 6 for a set time, the servo motor 1 7 is shut off, and the servo motor 2 12 is activated. The rotation of the double-headed reverse lead screw 10 moves the two connecting parts closer together until the two clamping plates 14 clamp the surface of the cardboard box. When the torque value of the servo motor 2 12 slightly exceeds the set value, the control module 8 reverses the servo motor 2 12, causing the two clamping plates 14 to retract. At this point, the visual recognition camera 13 is activated to capture images of the cardboard box. The control module 8 runs an image processing program to receive the images transmitted from the visual recognition camera 13. The system displays the images and analyzes the characteristics and positions of the cartons. When it detects that the cartons on the conveyor belt 5 are placed diagonally, the control module 8 starts the servo motor 20, which drives the rotating screw 17 to rotate, thereby pushing the movable part 21 to adjust to the appropriate position. The electric telescopic rod 19 is then activated, allowing its telescopic end adjustment head 18 to pass through the transverse groove 15 and touch the cartons, thus readjusting the angle of the cartons. After that, the clamping operation of the clamping plate 14 is repeated to center and straighten the cartons a second time. The visual recognition camera 13 is then activated again to take pictures and analyze them again until the state of the cartons meets the requirements. This structural design gives the centering structure of the assembly line conveyor device good state recognition and adjustment functions, and the structural design is reasonable.
