DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0018] Embodiment 1

[0019] The utility model takes the variable speed tray conveyor line for conveying battery cells as an example to further illustrate the utility model. Figure 1~Figure 3 As shown, the variable speed pallet conveyor line for conveying battery cells includes: a main conveyor line body 16 for conveying the pallet 8 along the first conveying plane at a set first speed; an auxiliary conveyor line body 17 for conveying the pallet 8 along the second conveying plane higher than the first conveying plane at a set second speed different from the first speed; the main conveyor line body 16 and the auxiliary conveyor line body 17 are arranged in parallel, and convey the pallet 8 to a designated position along the same conveying path respectively. The main conveyor line body 16 has a feed port for feeding in the pallet 8 and a discharge port for sending out the pallet 8; the auxiliary conveyor line body 17 is arranged in parallel with the main conveyor line body 16, and is located between the feed port and the discharge port.

[0020] The upper surface of the main conveyor line body 16 and the upper surface of the auxiliary conveyor line body 17 are not in the same plane in the initial condition. The main conveyor line body 16 is slightly higher than the auxiliary conveyor line body 17, and both are responsible for the radial conveyance of the battery cells. The movement directions of the main conveyor line body 16 and the auxiliary conveyor line body 17 are parallel. By setting the auxiliary conveyor line body 17 with adjustable speed parallel to the main conveyor line body 16, the conveying speed can be adjusted according to the different requirements of each process for the conveying speed, avoiding congestion of the production line and improving production efficiency; at the same time, when a blockage occurs in front during transportation, the auxiliary conveyor line body 17 rises to lift the tray 8 containing the battery cells and slows down, thereby reducing blockage and dust generation, improving production efficiency and product quality. The design of this variable speed pallet conveyor line solves the problem that the traditional conveyor line body cannot adjust the conveying rate.

[0021] The main conveyor line 16 includes a first motor 3, a first rotating shaft 4 and a belt 5. The output end of the first motor 3 is connected to the first rotating shaft 4, and the first rotating shaft 4 is installed on the frame 15 through a bearing assembly and a bearing sleeve 6. A pulley is installed on the first rotating shaft 4, and the pulley is used to drive the belt 5 to convey the pallet 8 along the first conveying plane. The first conveying plane is the contact surface between the belt 5 and the pallet 8.

[0022] The main conveyor line 16 drives the belt 5 through the first motor 3, thereby driving the main conveyor line 16 to move. In order to ensure the effective transportation of the battery cell pallet, the contact surface between the main conveyor line and the battery cell pallet (i.e., the contact surface between the belt 5 and the pallet 8) is the first conveying surface. The main conveyor line 16 is driven by the first motor 3 at a constant speed, which meets the conventional battery cell pallet transportation requirements and controls the main material transportation speed of the entire production line. The use of belt drive, on the one hand, has a softer contact with the pallet surface and will not damage the pallet or workpiece. On the other hand, when the product in the pallet is heavy, it can prevent the main conveyor line from overloading.

[0023] Two belts 5 are arranged in the main conveyor line body 16. The first rotating shaft 4 driven by the first motor 3 is the driving shaft. To ensure the effectiveness of the belt conveying, the conveyor line also includes at least one set of driven shafts 20. The driven shafts 20 are installed on the frame 15 through the driven shaft bearing sleeve 12 and the like.

[0024] The auxiliary conveyor line 17 includes a plurality of conveying units arranged between the feed port and the discharge port, each conveying unit includes: a power mechanism for conveying the tray 8 along the second conveying plane and a lifting mechanism for driving the power mechanism to lift the tray 8 from a set position below the first conveying plane to the second conveying plane.

[0025] According to the process requirements, a secondary conveyor line 17 is set in a certain conveying section where the battery tray needs to be accelerated or decelerated. After the battery tray enters the conveying section where the secondary conveyor line 17 is located, the lifting mechanism drives the power mechanism to rise, so that the battery tray is separated from the first conveying plane of the main conveyor line 16; at the same time, the power mechanism conveys the battery tray along the second conveying plane higher than the first conveying plane at a set second speed different from the first speed, thereby realizing the acceleration or deceleration of the battery tray. The utility model can adjust the moving speed of the battery tray through the secondary conveyor line, thereby solving the problem that the conveyor line in the prior art cannot change the conveying rate.

[0026] The power mechanism includes a servo motor 1, a second rotating shaft 10 and a roller 9; the second rotating shaft 10 is connected to the output end of the servo motor 1 through a coupling 2; the roller 9 is installed on the second rotating shaft 10 and is used to convey the pallet 8 along the second conveying plane; the second conveying plane is the contact surface between the roller 9 and the pallet 8 when the pallet 8 is conveyed through the auxiliary conveying line 17.

[0027] The output speed of the servo motor 1 is adjustable, and the servo motor 1 controls the speed of the roller 9, thereby realizing the adjustable conveying speed of the auxiliary conveyor line 17. The lifting mechanism controls the rise or fall of the power mechanism to realize the differential speed control of the tray.

[0028] The lifting mechanism includes a cylinder 13, a working end of the cylinder 13 is connected to the support plate, and a power mechanism is installed on the support plate; when the cylinder 13 drives the support plate to descend, the top surface of the roller 9 is located at a set position lower than the first conveying plane; when the cylinder 13 drives the support plate to rise, the top surface of the roller 9 is lifted to the position of the second conveying plane.

[0029] The use of the cylinder 13 in the lifting mechanism can make the auxiliary conveyor line 17 rise or fall more smoothly, avoid unnecessary bumps and vibrations to the pallet or the battery cells in the pallet, and protect the products and equipment from damage. At the same time, the use of the cylinder 13 to drive can provide a higher load-bearing capacity.

[0030] The lifting mechanism makes the upper surface of the auxiliary conveyor line body 17 above the upper surface of the main conveyor line body 16 through the cylinder 13. The lifting mechanism also includes a lower support block 18 arranged on the frame 15, and the lower support block 18 is used to install the cylinder 13. At the same time, the lower support block 18 is connected to the dustproof plate 14. The servo motor 1 is installed on the support plate through the upper support block 11, and the cylinder 13 drives the power mechanism to move up and down through the support plate; or the support plate is eliminated, and the upper support block 11 is appropriately extended to replace the support plate. The various components of the power mechanism such as the servo motor 1, the second rotating shaft 10 and the roller 9 are all installed on the upper support block 11, so that the structure is more simplified.

[0031] The main conveyor line body 16 and the auxiliary conveyor line body 17 are installed on the frame 15, and the frame 15 is supported on the ground by the foot support 7.

[0032] The foot support 7 in the utility model is an adjustable foot support, which is used to adjust the height of the frame so that the conveying surfaces of the main conveying line body 16 and the auxiliary conveying line body 17 remain horizontal, and the conveying is more stable, thereby reducing unnecessary energy consumption generated during the conveying process.

[0033] Two belts are arranged in the main conveyor line body 16, and a plurality of support plates 19 are arranged between the two belts. The support plates 19 are fixed on the frame 15. The tray 8 slides along the support plates 19 driven by the belts. The support plates 19 are used to share the weight of the tray 8. The roller 9 in the auxiliary conveyor line body 17 is located between the two belts (and between two adjacent support plates 19). By cooperating with the cylinder 13, the interference between the main conveyor line body 16 and the auxiliary conveyor line body 17 can be effectively avoided, and the main conveyor line body 16 and the auxiliary conveyor line body 17 can be prevented from interfering with each other.

[0034] A dustproof plate 14 is provided on the frame 15 , and the dustproof plate 14 is located below the main conveying line body 16 and the auxiliary conveying line body 17 .

[0035] The dustproof plate 14 is used to receive, collect and isolate dust in the production process, especially the dust generated when the tray is congested, so as to reduce dust pollution.

[0036] In the utility model, the servo motor 1 drives the roller 9 to drive the auxiliary conveyor line body 17 to move upward and forward. The auxiliary conveyor line body 17 is placed between the main conveyor line body 16. The output speed of the main conveyor line body 16 can be adjusted, and the height is controlled by the cylinder 13. When the cylinder is lifted upward, the height of the auxiliary conveyor line body 17 is higher than the plane of the main conveyor line body 16, and then the speed of a certain section of the battery tray can be adjusted by adjusting the speed of the servo motor. There are two transition planes between the auxiliary conveyor line body 17 and the main conveyor line body 16, wherein the first transition plane is the battery tray plane parallel to the main conveyor line plane, and the second transition plane is the auxiliary conveyor line plane higher than the main conveyor line plane.

[0037] The utility model can be installed on an automated workstation that needs to be quickly in and out, and a section of roller line (auxiliary conveyor line 17) is installed between the belt line (main conveyor line 16). The height of this section of the belt line is about 5 mm higher than the surface of the roller line. When the battery tray needs to slow down, the belt line drive is converted to roller line drive. The roller line is controlled by a servo motor, and the speed and acceleration of the roller line can be set. When the product enters and exits the workstation, rapid acceleration is adopted, and deceleration is performed when it needs to stop at the workstation, which can effectively improve the production efficiency and reliability of the equipment.

[0038] The utility model reduces the blockage between the trays and improves the production efficiency through differential speed control; reduces the stopping and restarting frequency of the trays and prolongs the service life of the equipment; reduces the generation of dust, improves the production environment and improves the product quality; adopts a simple and effective differential speed control scheme and is easy to implement and maintain.

[0039] Embodiment 2:

[0040] The only difference between this embodiment and the first embodiment is that in this embodiment, by comprehensively evaluating the movement characteristics of the pallets on the entire conveyor line, the auxiliary conveyor line body 17 described in the first embodiment is installed at appropriate intervals for the conveying sections that are prone to congestion, so that when congestion occurs when the pallets are conveyed along the main conveyor line body 16, the pallets are switched to be conveyed by the auxiliary conveyor line body 17, thereby solving the problem of pallet congestion in a targeted manner.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
