[0001] This utility model relates to the field of pallet positioning and transportation technology, and in particular to a pallet transfer device. Background Technology

[0002] After batteries and battery accessories are manufactured, they are often loaded onto pallets for transfer and storage. With the increasing automation of production workshops, robotic arms in conjunction with CCD cameras are commonly used to precisely grasp batteries and accessories. However, the positioning of these pallets still relies on CCD cameras. The robotic arm places the batteries and accessories onto the pallets one by one based on the pallet position information captured by the CCD camera. However, the pallet position information captured by the CCD camera consumes a significant amount of storage memory in the central control unit. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tray transfer device that can save the storage memory of the central control unit while ensuring accurate placement of batteries and battery accessories.

[0005] The first limiter is disposed on the first conveyor belt. The first limiter is located on the side of the positioning area facing the discharge end of the first conveyor belt. The first limiter has a limiting end close to the conveying surface of the first conveyor belt. The first limiter and the first conveyor belt are respectively connected to the photoelectric sensor.

[0006] Furthermore, the first limiter includes a first driver and a first baffle. The first driver is communicatively connected to a first photoelectric sensor. The first driver has a movable end close to the transmission surface of the first conveyor belt. The first baffle is connected to the movable end of the first driver.

[0007] Furthermore, the first conveyor belt is provided with a guide block, the length direction of which is parallel to the conveying direction of the first conveyor belt.

[0008] Furthermore, the pallet conveying device described above also includes a top holder, which is located on the side of the positioning area facing the feed end of the first conveyor belt. The top holder has a top holding end close to the conveying surface of the first conveyor belt, and the top holder is communicatively connected to the first photoelectric sensor.

[0009] Furthermore, the top holder includes a second driver and a contoured top block. The second driver is communicatively connected to a first photoelectric sensor. The second driver has a movable end close to the transmission surface of the first transmission belt. The contoured top block is connected to the movable end of the second driver.

[0010] Furthermore, the aforementioned pallet conveying device further includes a second conveyor belt and a material-picking suction cup; the second conveyor belt receives the material at the inlet end of the first conveyor belt, a storage rack is provided on the second conveyor belt, a second limiter is provided on the second conveyor belt, the storage rack has a storage space located above the conveying surface of the second conveyor belt, the second limiter has a limiting end extending into the storage space, and the material-picking suction cup reciprocates below the storage space and the conveying surface of the second conveyor belt.

[0015] The beneficial effects of this utility model are as follows: after the first conveyor belt sends the tray into the positioning area, it will be sensed by the first photoelectric sensor. At this time, the limiting end of the first limiter will approach the transmission surface of the first conveyor belt to prevent the tray from continuing to move, and the first conveyor belt will stop the transmission operation, thereby completing the positioning of the tray in the positioning area. This eliminates the need to use the tray position image information obtained by the CCD camera, thus saving the storage memory of the central control unit. Attached Figure Description

[0026] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figure 1 and Figure 2 As shown, this utility model discloses a pallet conveying device, including a first conveyor belt 1 and a first limiter 2; a positioning area is provided on the conveying path of the first conveyor belt 1, and a first photoelectric sensor 11 is provided on the first conveyor belt 1, with the detection end of the first photoelectric sensor 11 facing the positioning area; the first limiter 2 is disposed on the first conveyor belt 1, and the first limiter 2 is located on the side of the positioning area facing the discharge end of the first conveyor belt 1, and the first limiter 2 has a limiting end close to the conveying surface of the first conveyor belt 1; the first limiter 2 and the first conveyor belt 1 are respectively communicatively connected to the first photoelectric sensor 11.

[0028] Working principle: After the first conveyor belt 1 delivers the tray into the positioning area, it is detected by the first photoelectric sensor 11. At this time, the limiting end of the first limiter 2 will approach the transmission surface of the first conveyor belt 1 to prevent the tray from continuing to move. This prevents the tray from moving on the transmission surface of the first conveyor belt 1 due to inertia after the first conveyor belt 1 stops operating. This ensures the tray is positioned in the positioning area, allowing the robot arm to place the product into the corresponding groove on the tray according to the pre-set action program, without the need for position compensation in conjunction with a CCD camera.

[0029] In some implementations, please refer to Figure 2 As shown, the first limiter 2 includes a first driver 21 and a first baffle 22. The first driver 21 is communicatively connected to the first photoelectric sensor 11. The first driver 21 has a movable end near the transmission surface of the first conveyor belt 1, and the first baffle 22 is connected to the movable end of the first driver 21. The first driver 21 controls the movement of the first baffle 22 to achieve the positioning of the tray on the first conveyor belt 1.

[0030] It is worth noting that the first driver 21 can be a rotary cylinder, motor, or other device with a rotary drive mechanism that drives the first baffle 22 to approach the transmission surface of the first conveyor belt 1 in a rotating manner. The first driver 21 can also be a cylinder, hydraulic cylinder, electric cylinder, or other device with a linear reciprocating moving end that drives the first baffle 22 to approach the transmission surface of the first conveyor belt 1 in a lifting or translating manner.

[0031] In some implementations, please refer to Figure 2 As shown, the first conveyor belt 1 is provided with a guide block 12, the length direction of which is parallel to the conveying direction of the first conveyor belt 1. During the process of conveying the pallet, the first conveyor belt 1 uses the guide block 12 to contact the pallet to guide the pallet into the positioning area, and the guide block 12 ensures that the pallet enters the positioning area in the required posture.

[0032] It is worth noting that the end of the guide block 12 facing the feed end of the first conveyor belt 1 has a guide slope 121, which can be used to gradually guide the pallet into the positioning area in the required posture.

[0033] In some implementations, please refer to Figure 2 As shown, the pallet conveying device further includes a top holder 3, which is located on the side of the positioning area facing the feed end of the first conveyor belt 1. The top holder 3 has a top holding end close to the conveying surface of the first conveyor belt 1, and is communicatively connected to the first photoelectric sensor 11. After the pallet is positioned in the positioning area, the top holder 3 holds the pallet in the positioning area to ensure that the pallet will not shift in the positioning area without human intervention.

[0034] In some implementations, please refer to Figure 2 As shown, the top holder 3 includes a second driver 31 and a contoured top block 32. The second driver 31 is communicatively connected to the first photoelectric sensor 11 and has a movable end near the transmission surface of the first conveyor belt 1. The contoured top block 32 is connected to the movable end of the second driver 31. The second driver 31 controls the movement of the contoured top block 32 to fix the tray in the positioning area.

[0035] It is worth noting that the second actuator 31 can be a rotary cylinder, motor, or other device with a rotary drive mechanism that drives the contouring top block 32 to approach the tray in a rotating manner. The second actuator 31 can also be a cylinder, hydraulic cylinder, electric cylinder, or other device with a linear reciprocating moving end that drives the contouring top block 32 to approach the tray in a translational manner.

[0036] In some implementations, please refer to Figure 1 and Figure 3 As shown, the pallet conveying device further includes a second conveyor belt 4 and a material-picking suction cup 5; the second conveyor belt 4 is connected to the feeding end of the first conveyor belt 1, a storage rack 41 is provided on the second conveyor belt 4, a second limiter 42 is provided on the second conveyor belt 4, the storage rack 41 has a storage space located above the conveying surface of the second conveyor belt 4, the second limiter 42 has a limiting end extending into the storage space, and the material-picking suction cup 5 reciprocates below the storage space and the conveying surface of the second conveyor belt 4. By storing several pallets in the storage space of the storage rack 41, and suspending the pallets above the transmission surface of the second conveyor belt 4 by the second limiter 42, when it is necessary to replenish the first conveyor belt 1 with pallets, the picking suction cup 5 passes through the transmission surface of the second conveyor belt 4 and enters the storage space, pushing the pallets away from the limiting end of the second limiter 42, and adsorbing the pallet at the bottom of the storage space. Then, the limiting end of the second limiter 42 exits the storage space, and the picking suction cup 5 faces the second conveyor belt 4. The material pick-up suction cup 5 moves in the direction of the conveying surface. When the material pick-up suction cup 5 drives several trays to descend to the height of the upper tray of the second limiter 42, it stops. At this time, the limiter 42 re-enters the storage space to support the trays except those picked up by the material pick-up suction cup 5. Then, the material pick-up suction cup 5 continues to move towards the conveying surface of the second conveyor belt 4 and places the trays on the conveying surface of the second conveyor belt 4. Finally, the second conveyor belt 4 sends the trays into the feeding end of the first conveyor belt 1.

[0037] In some implementations, please refer to Figure 3 As shown, the second limiter 42 includes a third actuator 421 and a second baffle 422. The third actuator 421 has a movable end that extends into the storage space, and the second baffle 422 is connected to the movable end of the third actuator 421. The third actuator 421 controls the movement of the second baffle 422 to lift the pallet in the storage space.

[0038] It is worth noting that the third actuator 421 can be a device with a linear reciprocating moving end, such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder, that drives the second baffle 422 to move closer to the tray in a translational manner.

[0039] In some implementations, please refer to Figure 2As shown, a second photoelectric sensor 13 is provided at the feed end of the first conveyor belt 1, and the second photoelectric sensor 13 is communicatively connected to the second conveyor belt 4. The second photoelectric sensor 13 is used to determine whether there is a tray at the feed end of the first conveyor belt 1, so as to avoid the second conveyor belt 4 feeding a new tray into the feed end of the first conveyor belt 1 when there is a tray at the feed end of the first conveyor belt 1.

[0040] In some implementations, please refer to Figure 3 As shown, a third photoelectric sensor 411 is installed on the storage rack 41, with the detection end of the third photoelectric sensor 411 facing the storage space. The third photoelectric sensor 411 is used to determine whether the trays in the storage rack 41 are about to run out, so as to prompt on-site personnel to replenish the material through audible and visual warning devices, central control units, and other equipment.

[0041] In some implementations, please refer to Figure 3 and Figure 4 As shown, the pallet conveying device further includes a mounting frame 6 and a fourth driver 7. The mounting frame 6 is connected to the frame of the second conveyor belt 4, and the fourth driver 7 is disposed on the mounting frame 6. The fourth driver 7 has a movable end that moves in a vertical direction, and the material-picking suction cup 5 is connected to the movable end of the fourth driver 7. The fourth driver 7, which drives the material-picking suction cup 5, is positioned below the conveying surface of the second conveyor belt 4 by the mounting frame 6.

[0042] It is worth noting that the fourth actuator 7 can be a device with a linear reciprocating moving end, such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder, that drives the material suction cup 5 to move vertically.
