Description

Technical Field

[0001] This application relates to the field of battery production, and in particular to a lifting and positioning device and docking equipment. Background Technology

[0002] During battery production, batteries need to be charged, discharged, or tested. Batteries are typically held on a tray during these processes. Existing trays have clearance holes on both sides to avoid probes. Different battery models correspond to different probes. When a battery has a larger probe, the probe cannot pass through the clearance holes to connect with the battery's electrodes, requiring the battery to be removed from the tray before connection.

[0003] Existing battery testing equipment uses a method of lifting the battery from the bottom and positioning it from the top via a positioning component. The lifting mechanism and the positioning component are driven separately. Within a limited space, the equipment's compatibility with battery height is limited, resulting in poor compatibility. Summary of the Invention

[0037] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a lifting and positioning device 100. As... Figure 3 As shown, the tray 300 is used to carry batteries. The lifting and positioning device 100 can lift the batteries in the tray 300 and position the lifted batteries. The lifting and positioning device 100 includes a first base 1, a first lifting mechanism 2, a second lifting mechanism 3, and a positioning mechanism 4.

[0039] The first base 1 supports other mechanisms of the lifting and positioning device 100. Optionally, the first base 1 includes two flush mounting plates. The lifting and positioning device 100 also includes a conveying mechanism 5, which may be mounted on the first base 1 or on a separate frame. The conveying mechanism 5 includes a plurality of sequentially arranged conveying rollers located between the two mounting plates. The conveying rollers are driven by a driver to convey the pallet 300.

[0040] The first lifting mechanism 2 is mounted on the first base 1. The first lifting mechanism 2 is used to lift and position the pallet 300. After the conveying mechanism 5 transports the pallet 300 to the designated position, the first lifting mechanism 2 lifts the pallet 300, causing the pallet 300 to detach from the conveying mechanism 5. The first lifting mechanism 2 also positions the pallet 300 to prevent unnecessary movement of the pallet 300.

[0041] The second lifting mechanism 3 is installed on the first base 1. After the first lifting mechanism 2 lifts the tray 300, the second lifting mechanism 3 is used to lift the battery in the tray 300, so that the battery can be removed from the tray 300, so that the docking component can dock with the battery.

[0042] The positioning mechanism 4 is connected to the second lifting mechanism 3. When the second lifting mechanism 3 lifts the battery, it drives the positioning mechanism 4 to rise synchronously with the battery, maintaining a constant distance between the battery and the positioning mechanism 4. After the battery is lifted into position, the second lifting mechanism 3 supports the battery from below, while the positioning mechanism 4 positions the battery from above to prevent movement of the battery during the docking process.

[0043] In the lifting and positioning device 100 of this embodiment, the second lifting mechanism 3 can drive the battery and the positioning mechanism 4 to rise synchronously, ensuring a large distance between the positioning mechanism 4 and the battery, and improving the compatibility range of the lifting and positioning device 100 with the battery. After the battery is lifted into position, the positioning mechanism 4 and the second lifting mechanism 3 cooperate to position the lifted battery, improving the positioning stability of the battery and facilitating subsequent docking processes.

[0044] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the first lifting mechanism 2 includes a first lifting component 21 and a first driving component 22.

[0045] The first lifting assembly 21 is vertically and elliptically mounted on the first base 1. The first lifting assembly 21 includes a support and positioning assembly and a lifting seat 215, with the support and positioning assembly disposed on the lifting seat 215. For example, the support and positioning assembly includes a first support column 211, a first support member 212, a first guide column 213, and a first positioning plate 214.

[0046] The lifting seat 215 is located below the first base 1. One end of the first support column 211 is connected to the lifting seat 215, and the other end of the first support column 211 is connected to the first support member 212. One end of the first guide column 213 is connected to the lifting seat 215, and the other end of the first guide column 213 passes through the first base 1. The first guide column 213 is movable relative to the first base 1. The first positioning plate 214 is located above the first base 1 and is connected to the first guide column 213. Optionally, there are two first positioning plates 214, which are flush with each other, and multiple first support members 212 are located between the first positioning plates 214.

[0047] When the lifting seat 215 rises, it drives the support positioning assembly to rise accordingly. During the rising process, the first support member 212 contacts the pallet 300, lifting it. The first positioning plate 214 is provided with a positioning pin that mates with the pallet 300, used to position the pallet 300 and prevent unnecessary movement. The first drive assembly 22 is located on the first base 1 and connected to the support positioning assembly, used to drive the support positioning assembly to rise and fall. The first drive assembly 22 can be a cylinder, hydraulic cylinder, or motor.

[0048] For example, the first drive component 22 is fixed on the first base 1, and the output end of the first drive component 22 is connected to the lifting seat 215. The first drive component 22 drives the lifting seat 215 and the support and positioning components on the lifting seat 215 to move up and down.

[0049] Optionally, the first lifting mechanism 2 also includes a limit switch, for example, a proximity sensor. The limit switch is set on the first base 1. After the first lifting component 21 lifts the tray 300 into place, it triggers the limit switch, and the first drive component 22 stops working.

[0050] Optionally, the first lifting mechanism 2 further includes a limiting post 23, which is disposed on the lifting base 215. When the support positioning component rises to its limit position, the limiting post 23 abuts against the first base 1 to prevent the support positioning component from over-lifting the tray. Optionally, there may be multiple limiting posts 23, and the positions of the limiting posts 23 may be set according to requirements.

[0051] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the second lifting mechanism 3 includes: a second lifting component 31 and a second driving component 32.

[0052] The second lifting assembly 31 is vertically and elliptically mounted on the first base 1, and the second lifting assembly 32 is used to lift the battery in the tray 300. For example, the second lifting assembly 31 includes a second support column 311 and a second support member 312, with the second support member 312 disposed at the end of the second support column 311.

[0053] like Figure 3 As shown, the tray 300 is provided with a lifting through hole 301, which is adapted to the second support member 312. The second support member 312 can lift the battery in the tray 300 through the lifting through hole 301.

[0054] The second drive assembly 32 is disposed on the first base 1 and is connected to the second lifting assembly 31, and is used to drive the second lifting assembly 31 to rise and fall. The rising and falling of the second lifting assembly 31 can drive the battery in the tray 300 to rise and fall, which facilitates the docking of the battery.

[0055] In some embodiments, the second lifting mechanism 3 further includes a support base 33 and a fixing column 34. One end of the fixing column 34 is connected to the first base 1, and the other end of the fixing column 34 is connected to the support base 33. The support base 33 is located below the first base 1. The second lifting assembly 31 and the second driving assembly 32 are both disposed on the support base 33. For example, a second guide column 35 is disposed on the support base 33, and the second lifting assembly 31 is slidably connected to the second guide column 35. Optionally, there may be multiple second guide columns 35. The second driving assembly 32 is used to drive the second lifting assembly 31 to rise and fall.

[0056] like Figures 7-10 As shown, in some embodiments, the second drive assembly 32 includes a second drive member 321 and a lead screw 322. Optionally, the second drive member 321 is a motor, and there are two lead screws 322. Both the second drive member 321 and the two lead screws 322 are mounted on the support base 33. The output end of the second drive member 321 drives the two lead screws 322 to rotate simultaneously via a synchronous belt 323. The lead screws 322 are threadedly engaged with the second lifting assembly 31, and the rotation of the lead screws 322 drives the second lifting assembly 31 to rise and fall.

[0057] In some embodiments, the second lifting assembly 31 further includes a lifting plate 313, and a second support column 311 is disposed on the lifting plate 313. A lead screw 322 is threadedly engaged with the lifting plate 313, and the lifting of the lifting plate 313 can drive the second support column 311 and the second support member 312 to rise and fall.

[0058] like Figure 11 , Figure 12 and Figure 13 As shown, the positioning mechanism 4 includes a support component 41, a positioning element 42, and a third drive component 43.

[0059] The support assembly 41 is connected to the second lifting mechanism 3, and the support assembly 41 is slidably connected to the first base 11. Optionally, the support assembly 41 includes a bottom support member 411, a third support column 412, and a top support member 413. One end of the third support column 412 is connected to the bottom support member 411, and the other end of the third support column 412 passes through the first base 11 and is connected to the top support member 413. The third support column 412 is slidable relative to the first base 11. The bottom support member 411 is connected to the second lifting mechanism 3. For example, the bottom support member 411 is provided with a connector 48, which is connected to the lifting plate 313 of the second lifting mechanism 3. When the lifting plate 313 is raised or lowered, it can drive the support assembly 41 to be raised or lowered synchronously.

[0060] The positioning element 42 is slidably connected to the support component 41. For example, the positioning element 42 is slidably disposed on the top support component 413. After the second lifting mechanism 3 lifts the battery up a preset distance, the positioning element 42 moves down to position the lifted battery, and the second lifting mechanism 3 continues to lift the battery to the docking position.

[0061] like Figure 14 As shown, multiple positioning elements 42 are sequentially arranged on the support assembly 41, and each positioning element 42 has a positioning groove 421 adapted to the battery. When the positioning element 42 moves down, the top of the battery enters the positioning groove 421, preventing the battery from moving during docking.

[0062] The third drive component 43 is disposed on the support component 41. For example, the third drive component 43 is disposed on the top support 413. The third drive component 43 is connected to the positioning component 42 and is used to drive the positioning component 42 to move up and down.

[0063] The positioning mechanism 4 is driven to rise and fall by the second lifting mechanism 3, and the positioning component 42 is driven to rise and fall by the third driving component 43 to complete the positioning of the battery, which can effectively improve the space utilization of the lifting and positioning device 100.

[0064] Optionally, the positioning mechanism 4 further includes a support mounting member 44, which is slidably connected to the support assembly 41. For example, the third drive assembly 43 includes a third drive member 431 and a third guide post 432. The third drive member 431 is disposed on the top support member 413, and its output end is connected to the support mounting member 44 to drive the support mounting member 44 to move up and down. Optionally, the third drive member 431 is a cylinder. The end of the third guide post 432 is connected to the support mounting member 44, and the third guide post 432 is slidably connected to the top support member 413 to guide the movement of the support mounting member 44. Multiple positioning members 42 are sequentially disposed on the support mounting member 44. The third drive assembly 43 drives the positioning members 42 to move up and down by driving the support mounting member 44 to move up and down.

[0065] In some embodiments, the positioning mechanism 4 further includes a fourth drive assembly 45 and a pusher 46. The fourth drive assembly 45 is disposed on the support mounting member 44. The pusher 46 is located below the support mounting member 44, and the output end of the fourth drive assembly 45 is connected to the pusher 46, driving the pusher 46 to move up and down. For example, the fourth drive assembly 45 includes a cylinder, and the output end of the cylinder is connected to the pusher 46.

[0066] After the battery docking is completed, the positioning component 42 rises to detach from the battery. Some batteries may get stuck in the positioning groove 421 of the positioning component 42. When the positioning component 42 rises, the fourth drive assembly 45 drives the pushing component 46 to descend. The pushing component 46 contacts the battery, ensuring that the battery is separated from the positioning component 42 and improving the safety of the lifting and positioning device 100.

[0067] Optionally, a buffer 47 is provided on the third support column 412. The buffer 47 can be an existing buffer structure. The buffer 47 can contact the upper surface of the first base 11 and play a buffering role when the positioning mechanism 4 descends.

[0068] like Figure 15 As shown, a scale 49 is provided on the side wall of the support mounting component 44. The scale 49 is used to indicate the position of the positioning component when adjusting the positioning component during model change.

[0069] like Figure 1 and Figure 2 As shown, the lifting and positioning device 100 further includes a first limiting component 6 and a second limiting component 7. Both the first limiting component 6 and the second limiting component 7 are connected to the support component 41 of the positioning mechanism 4. The first limiting component 6 and the second limiting component 7 limit the position of the pallet 300.

[0070] During the conveying process of pallet 300 by conveying mechanism 5, the second limiting component 7 can make way for pallet 300 when it enters, for example, pallet 300 passes over the second limiting component 7. The first limiting component 6 can limit pallet 300 when it enters, stopping it at a preset position. The second lifting component 31 of the second lifting mechanism 3 rises, driving the second limiting component 7 to rise via the support component 41, restricting pallet 300 from moving in the opposite direction of the feeding direction. The first limiting component 6 and the second limiting component 7 do not require separate drives, reducing costs.

[0071] like Figure 16 and Figure 17 As shown, both the first limiting component 6 and the second limiting component 7 include a support plate 61 and a baffle 62. The support plate 61 is disposed on the first base 11, and the baffle 62 is disposed on the support plate 61. The position of the baffle 62 of the first limiting component 6 is higher than the position of the baffle 62 of the second limiting component 7.

[0072] For example, a pad 63 is provided between the support plate 61 and the first base 11, and the pad 63 is located on the upper surface of the support plate 61. The fourth guide post 64 is slidably disposed on the support plate 61, and the baffle 62 is disposed at the top of the fourth guide post 64. An elastic element 65 is sleeved on the fourth guide post 64, and the elastic element 65 is located between the support plate 61 and the baffle 62. Optionally, the elastic element 65 is a spring, which is compressed when the baffle 62 moves down. One end of the pull rod 66 passes through the support plate 61 and is connected to the baffle 62, and the other end of the pull rod 66 is connected to the bottom support member 411 of the positioning mechanism 4. The pull rod 66 can drive the baffle 62 to rise and fall.

[0073] The thickness of the pad 63 of the second limiting component 7 is greater than the thickness of the pad 63 of the first limiting component 6, so that the position of the baffle 62 of the first limiting component 6 is higher than the position of the baffle 62 of the second limiting component 7.

[0074] Optionally, both the first limiting component 6 and the second limiting component 7 further include a sensing plate 67 and a sensor 68. The sensing plate 67 is disposed on the support plate 61, and the sensor 68 is disposed on the baffle 62. When the sensor 68 senses the sensing plate 67, it indicates that the elastic element 65 has been compressed to its limit, and the second lifting component 31 stops moving downward.

[0075] like Figure 1 As shown, an embodiment of this application provides a docking device, which includes a lifting and positioning device 100 as described above and at least one docking component 200, the docking component 200 being used to charge, discharge or test a battery.

[0076] like Figure 18 and Figure 19 As shown, the docking assembly 200 includes a second base 201, a probe assembly 205, and a fifth drive assembly.

[0077] The probe assembly 205 is slidably connected to the second base 201. For example, a slide rail 202 is provided on the second base 201, a slider 203 is slidably disposed on the slide rail 202, an adapter plate 204 is disposed on the slider 203, and the probe assembly 205 is disposed on the adapter plate 204. Optionally, the probe assembly 205 includes a plurality of probes arranged in sequence, the probes being used to mate with the tabs of the battery, and the plurality of probes can mate with the corresponding batteries respectively.

[0078] The fifth drive assembly is used to drive the probe assembly 205 to a position where it docks with the battery. For example, the fifth drive assembly includes a fifth driver 206 and a second lead screw 207. The fifth driver 206 can be a motor. The output end of the fifth driver 206 is connected to the second lead screw 207. The adapter plate 204 is threadedly engaged with the second lead screw 207. The rotation of the second lead screw 207 can cause the adapter plate 204 to slide, so that the probe docks with or moves away from the battery.

[0079] The steps for charging, discharging, or testing the battery using the docking device in this application include:

[0080] The conveying mechanism 5 transports the pallet 300 to the preset position, and the first limiting component 6 limits the pallet 300.

[0081] The first lifting mechanism 2 lifts the pallet 300 and positions it.

[0082] The second lifting component 31 of the second lifting mechanism 3 rises to lift the battery in the tray 300. At the same time, the baffle 62 of the positioning mechanism 4, the baffle 62 of the first limiting component 6 and the baffle 62 of the second limiting component 7 rise synchronously with the second lifting component 31, and the second lifting component 31 lifts the battery to the preset position.

[0083] The positioning component 42 of the positioning mechanism 4 descends to position the battery;

[0084] The probe assembly 205 of the docking assembly 200 slides towards the battery so that the probe docks with the battery's tabs to complete the charging, discharging or testing of the battery.

[0085] The probe assembly 205 of the docking assembly 200 slides away from the battery to separate the probe from the battery;

[0086] Positioning component 42 rises, pushing component 46 falls, and pushing component 46 contacts the battery to ensure that the battery is separated from positioning component 42.

[0087] The second lifting component 31 of the second lifting mechanism 3 drives the positioning mechanism 4, the baffle 62 of the first limiting component 6, and the baffle 62 of the second limiting component 7 to descend and reset synchronously with the second lifting component 31;

[0088] The first lifting mechanism 2 is reset.

[0089] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the technical solutions and core ideas of this application. Therefore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application. In summary, the content of this specification should not be construed as a limitation of this application.
