Description

Technical Field

[0001] This application relates to the field of battery cell manufacturing technology, and in particular to a battery cell shelf positioning platform. Background Technology

[0002] Solar cells are the core component of solar photovoltaic (PV) modules, typically referring to photoelectric conversion units made of monocrystalline or polycrystalline silicon. They directly convert sunlight into electrical energy and are the most fundamental photoelectric conversion devices in PV power generation systems, widely used in solar panels.

[0003] During the processing of solar cells, they may need to be transferred between different processing modules. This is usually achieved by using AGVs in conjunction with shelves. The transport robot neatly stacks the solar cells in the shelves, and after the AGVs drive the shelves to complete the transfer, the transport robot still removes the stacked solar cells.

[0004] However, the stopping position of the AGV is inevitably subject to error. Therefore, when the handling robot picks up the battery cells, the battery cells may be damaged due to the deviation in the picking position, resulting in huge economic losses, which is a significant shortcoming. Utility Model Content

[0005] To improve the stopping position accuracy of AGV trolleys, this application provides a battery cell shelf positioning platform.

[0006] The battery cell shelf positioning platform provided in this application adopts the following technical solution: A battery cell shelf positioning platform includes a frame arranged next to a handling robot. The frame includes two parallel side panels and an end panel arranged between the same end of the two side panels. Each side panel is equipped with a positioning cylinder electrically connected to a control system. The piston rods of the positioning cylinders on the two side panels are arranged opposite to each other. The piston rods of the positioning cylinders are threadedly connected to a roller seat for pushing the shelf. The end panel is also equipped with a positioning component for positioning the shelf along the length of the side panels.

[0007] By adopting the above technical solution, when the AGV trolley moves the shelf between the two side panels and stops, the lifting part of the AGV trolley relative to the shelf retracts downward, so that the shelf is suspended on the two side panels. Then, the positioning cylinders on the two side panels extend simultaneously, so that the corresponding roller seats abut against the shelf and can push it to move slightly. At the same time, the positioning component can also position the AGV trolley along the length of the side panel, ensuring that the shelf is accurately positioned to the predetermined position, and the subsequent handling robot can accurately pick up and put in the battery cells.

[0008] Optionally, the two side panel frames are also equipped with roller seats to support the shelves and suspend them in the air.

[0009] By adopting the above technical solution, the roller seat 2 can support the suspended shelf, and at the same time facilitates the positioning cylinder to push the shelf to make fine adjustments to its position.

[0010] Optionally, the positioning element includes a telescopic rotary cylinder electrically connected to the control system, wherein a pull rod is arranged on the piston rod of the telescopic rotary cylinder to form an L-shape therewith.

[0011] By adopting the above technical solution, during the retraction of the piston rod of the telescopic rotary cylinder, the pull rod can rotate to a vertical position, contact the shelf, and move it to the predetermined position, further improving the accuracy of the shelf position.

[0012] Optionally, the end plate frame is provided with a mounting plate base, and the mounting plate base is threadedly connected with a limiting bolt for the shelf to abut against.

[0013] By adopting the above technical solution, when the pull rod moves the shelf to the point where it abuts the limit bolt, the positioning is completed and accurate.

[0014] Optionally, the positioning component includes a second mounting plate base, on which a hollow cylindrical base is arranged. A straight sliding groove is formed along the axial direction of the inner wall of the cylindrical base, and a spiral groove communicating with the straight sliding groove is also formed circumferentially on the inner wall of the cylindrical base. A lever is coaxially slidably and rotatably passed through the cylindrical base. The lever is provided with protrusions that slide and cooperate with the straight sliding groove and the spiral groove. One end of the lever protrudes from the cylindrical base and is L-shaped, while the other end slides and rotatably passes through the second mounting plate base and is threadedly connected to an anti-loosening nut. A reset spring is provided on the outer sleeve of the cylindrical base, supporting the second mounting plate base and the L-shaped end of the lever. A pull line is attached to the end of the lever opposite the anti-loosening nut. The pull line is redirected by multiple reversing wheels and then attached to a first roller base.

[0015] By adopting the above technical solution, when the piston rod of the positioning cylinder extends, the pull line can pull the lever to move away from the shelf. The protrusion first slides along the spiral groove, so the lever rotates while sliding, until the protrusion slides in the straight groove. At this point, the lever only slides and can pull the shelf to move accurately to the predetermined position.

[0016] Optionally, the side plate frame is provided with a slide rail parallel to it, a slide plate is slidably arranged on the slide rail, a fastening bolt is threadedly connected to the slide plate, a rotating cylinder is rotatably sleeved on the fastening bolt, the fastening bolt is used to press the rotating cylinder against the slide plate, and the rotating cylinder is provided with a wire hole for the pull wire to pass through.

[0017] By adopting the above technical solution, during the installation process, if the pull cable is too long, the piston rod of the positioning cylinder will extend, and the worker will manually pull the pull cable to make the lever move the shelf to the predetermined position. Then the worker will rotate the drum so that all the excess length of the pull cable is wound around the drum, and tighten the fastening bolts to press the drum against the slide plate. When the lever moves the shelf to position later, the pull cable can pull the slide plate to slide back and forth on the slide rail.

[0018] Optionally, limit plates are provided at both ends of the slide rail.

[0019] By adopting the above technical solution, the limiting end plate can limit the sliding plate that slides on the slide rail, reducing the possibility that the sliding plate will be accidentally pulled off the slide rail.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When the AGV trolley moves the shelf between the two side panels and stops, the lifting part of the AGV trolley relative to the shelf retracts downward, so that the shelf is suspended on the two side panels. Then, the positioning cylinders on the two side panels extend simultaneously, so that the corresponding roller seats abut against the shelf and can push it to move slightly. At the same time, the positioning component can also position the AGV trolley along the length of the side panel, ensuring that the shelf is accurately positioned to the predetermined position, so that the subsequent handling robot can accurately pick up and put in the battery cells. 2. As the piston rod of the positioning cylinder extends, the pull cable can pull the lever to move. The protrusion first slides along the spiral groove, so the lever rotates while sliding until the protrusion slides in the straight groove. At this point, the lever only slides and can pull the shelf to move accurately to the predetermined position. 3. During installation, the pull cable may be too long. In this case, the piston rod of the positioning cylinder extends, and the worker manually pulls the pull cable to make the lever move the shelf to the predetermined position. Then the worker rotates the drum so that all the excess length of the pull cable is wound around the drum, and tightens the fastening bolts to press the drum against the slide plate. When the lever moves the shelf to position later, the pull cable can pull the slide plate to slide back and forth on the slide rail. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a battery cell shelf positioning platform.

[0028] Example 1 Reference Figure 1 The battery cell rack positioning platform includes a frame 1 placed next to the handling robot. The frame 1 includes two horizontal and parallel side plate frames 11 and an end plate frame 12 integrally formed between the same end of the two side plate frames 11. The other end of the two side plate frames 11 is open and used for AGV trolley to enter and exit.

[0029] Reference Figure 1 Two positioning cylinders 2, which are electrically connected to the control system, are bolted to each of the two side plate frames 11. The piston rods of the positioning cylinders 2 on the two side plate frames 11 are arranged opposite to each other. The positioning cylinders 2 on the two side plate frames 11 can adopt different models in the prior art. The piston rods of the positioning cylinders 2 are threadedly connected to roller seats 3 for pushing the top shelf.

[0030] Reference Figure 1 Each of the two side panel frames 11 is also equipped with multiple roller seats 2 4 for supporting the shelf and suspending it in the air. The roller seats 2 4 are slidably arranged on the side panel frames 11. By adjusting the support position of the roller seats 2 4, the support effect on the shelf can be improved.

[0031] Reference Figure 1 The end plate frame 12 is also provided with a positioning component for positioning the shelf along the length of the side plate frame 11. The positioning component includes a telescopic rotary cylinder 51 electrically connected to the control system. A pull rod 52 forming an L-shape with the piston rod of the telescopic rotary cylinder 51 is threaded onto the piston rod of the telescopic rotary cylinder 51.

[0032] Reference Figure 1 The piston rod of the telescopic rotary cylinder 51 can extend and retract, and can also rotate, so that the pull rod 52 remains horizontal before the AGV trolley enters between the two side frames 11.

[0033] When the AGV stops moving, its movable part used to support the shelf retracts downward, so that the shelf is suspended on the roller seat 4. At this time, the positioning cylinder 2 and the telescopic rotary cylinder 51 are activated.

[0034] The piston rod of the telescopic rotary cylinder 51 retracts. During the retraction process, the pull rod 52 rotates from horizontal to vertical, so that the pull rod 52 can hook the bottom of the shelf and drive it to move, thereby achieving precise positioning.

[0035] Reference Figure 1 The end plate frame 12 is bolted with a mounting plate base 53, and the mounting plate base 53 is threaded with a limit bolt 54 for the shelf to abut against. When the pull rod 52 moves the shelf to abut against the limit bolt 54, the shelf is positioned accurately.

[0036] The implementation principle of Example 1 is as follows: When the AGV trolley moves the shelf between the two side panel frames 11 and stops, the lifting part of the AGV trolley relative to the shelf retracts downward, so that the shelf is suspended on the roller seat 4. Then, the positioning cylinders 2 on both side panel frames 11 extend simultaneously, so that the corresponding roller seat 3 abuts against the shelf and can push it to move slightly. At the same time, the piston rod of the telescopic rotary cylinder 51 retracts, and the pull rod 52 can also position the AGV trolley along the length of the side panel frame 11, ensuring that the shelf is accurately positioned to the predetermined position, and the subsequent handling robot can accurately pick up and put in the battery cells.

[0037] Example 2 Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the positioning component includes a mounting plate seat 2 61 bolted to the end plate frame 12, and a hollow cylindrical seat 62 is bolted to the mounting plate seat 2 61. A straight sliding groove 621 is provided on the inner wall of the cylindrical seat 62 along its axial direction, and a spiral groove 622 communicating with the straight sliding groove 621 is also provided on the inner wall of the cylindrical seat 62 circumferentially.

[0038] A lever 63 is coaxially slidable and rotatable inside the cylinder seat 62. The lever 63 has an integrally formed protrusion (not shown in the figure) that slides and engages with the straight groove 621 and the spiral groove 622. One end of the lever 63 extends out of the cylinder seat 62 and is L-shaped, while the other end slides and rotatably passes through the mounting plate seat 61 and is threaded with an anti-loosening nut 64.

[0039] The sleeve of the cylinder base 62 is provided with a reset spring 65 that supports the mounting plate base 61 and the L-shaped end of the lever 63. The end of the lever 63 opposite to the anti-loosening nut 64 is attached with a pull wire 66. The pull wire 66 is tied to the roller base 3 after being reversed by multiple reversing wheels 67.

[0040] Reference Figure 2 and Figure 4A parallel slide rail 71 is bolted to the side plate frame 11, and a slide plate 72 is slidably arranged on the slide rail 71. Limiting end plates (not shown in the figure) are bolted to both ends of the slide rail 71. A fastening bolt 73 is threaded onto the slide plate 72, and a rotating cylinder 74 is rotatably sleeved on the fastening bolt 73. The fastening bolt 73 is used to press the rotating cylinder 74 against the slide plate 72. A wire hole 741 is opened on the rotating cylinder 74 for the pull wire 66 to pass through.

[0041] Reference Figure 2 and Figure 4 To facilitate installation, the pull cable 66 can be left with sufficient length in advance. Then, the piston rod of the positioning cylinder 2 extends, and the worker manually pulls the pull cable 66 to make the lever 63 move the shelf to the predetermined position. After that, the worker rotates the rotating drum 74 so that all the excess length of the pull cable 66 is wound around the rotating drum 74, and tightens the fastening bolt 73 to press the rotating drum 74 against the slide plate 72.

[0042] The implementation principle of Example 2 is as follows: When the piston rod of the positioning cylinder 2 extends, the pull wire 66 can pull the lever 63 to move. The protrusion first slides along the spiral groove 622. Thus, the lever 63 rotates while sliding. When the protrusion slides in the straight slide groove 621, the lever 63 only slides and can pull the shelf to move accurately to the predetermined position.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
