[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0040] The embodiment of the present invention provides a feeding device 1000, which is mainly used to feed batteries to a vacuum sealer 2000 to facilitate packaging. Figures 1 to 3 As shown, the loading device 1000 is provided with a material taking station (such as Figure 2 The loading device 1000 includes a frame 10, a first transport mechanism 20, a positioning mechanism 30 and a second transport mechanism 40; the first transport mechanism 20 is mounted on the frame 10 and is located at the positioning station of the material retrieving station. The first transport mechanism 20 is used to transfer the battery from the material retrieving station; the positioning mechanism 30 is mounted on the frame 10. The positioning mechanism 30 includes a placement table 31, a first positioning component 312 and a second positioning component 313. The placement table 31 is used to carry the battery. The first positioning component 312 and the second positioning component 313 are both mounted on the placement table 31. The first positioning component 312 is used to position the battery in a first direction (such as Figure 1 The second positioning assembly 313 is used to position the battery in the second direction (as shown in the X direction in FIG. Figure 1 The first direction is perpendicular to the second direction (as shown in the Y direction in FIG). A second transport mechanism 40 is mounted on the frame 10 and is used to transfer the batteries from the placement table 31 to the vacuum sealer 2000. The loading device 1000 can be externally mounted to the vacuum sealer 2000 to assist in automatic material supply and removal, greatly improving production efficiency. Furthermore, when feeding the vacuum sealer 2000, the loading device 1000 does not require the use of a visual positioning device to locate and remove the batteries, thereby reducing manufacturing costs.

[0041] Specifically, on the one hand, the loading device 1000 can transfer the battery from the material-retrieving station to the placement table 31, and finally realize automatic loading of the vacuum sealer 2000 through the second transport mechanism 40. Compared with the embodiment of the prior art in which the staff places the batteries one by one into the vacuum sealer 2000 and performs the packaging, its production efficiency is higher. On the other hand, the loading device 1000 is provided with a positioning mechanism 30, whose first positioning component 312 and second positioning component 313 can correct the position of the battery, so that the battery can be more accurately positioned on the placement table 31. This allows the second transport mechanism 40 to directly rely on the position information of the positioning mechanism 30 to dock with the placement table 31 and retrieve the material, without the need to use a visual positioning device for additional positioning confirmation. It can be seen that the loading device 1000 not only realizes the automated loading process and improves production efficiency, but also simplifies the system structure and reduces costs.

[0042] Reference Figure 4 and Figure 5 In one embodiment, the first positioning assembly 312 of the placement table 31 includes a positioning rib 312a, a first driving member 312b, and a first positioning block 312c connected to the first driving member 312b. The first positioning block 312c and the positioning rib 312a are arranged opposite each other in a first direction. The second positioning assembly 313 includes a second driving member 313a and a second positioning block 313b connected to the second driving member 313a. The first driving member 312b is used to drive the first positioning block 312c to move in the first direction so that the battery can contact the positioning rib 312a. The second driving member 313a is used to drive the second positioning block 313b to move in the second direction. With this arrangement, after the battery is transferred from the first picking assembly 21 to the placement table 31, the first positioning assembly 312 and the second positioning assembly 313 cooperate to correct the battery position, ensuring that each battery is in the same position when transported to the loading station. This effectively prevents positional deviation of the battery during transportation and enables the robot 42 to retrieve the battery based solely on position information during subsequent operations, thereby achieving cost savings. Specifically, the first driving member 312b and the second driving member 313a are both cylinders.

[0043] In addition, by implementing the above embodiment, the first positioning block 312c and the second positioning block 313b can respectively apply pressure to the contacting parts of the battery when positioning the battery, so as to make the outer surface of the battery smoother, which is beneficial for subsequent packaging.

[0044] Furthermore, the placement platform 31 includes a placement surface 311a and an outer side surface 311c surrounding the placement surface 311a. The placement surface 311a is used to receive the battery and is provided with a suction hole group 311b. The outer side surface 311c is provided with a connection port 311d that communicates with the suction hole group 311b. The connection port 311d is used to connect to a negative pressure device. With this arrangement, after the battery is positioned, the negative pressure device generates negative pressure and draws a vacuum to the connection port 311d, causing the suction holes to generate suction to absorb the battery, thereby improving the stability of the battery positioning and preventing the battery from shifting during transportation by the positioning mechanism 30.

[0045] The number of suction hole groups 311b can be adjusted based on the size of the battery and is not limited here. For example, multiple suction hole groups 311b are provided. Multiple suction hole groups 311b are arranged at intervals in the second direction, and suction hole group 311b includes multiple suction holes arranged at intervals in the first direction.

[0046] In one embodiment, the loading device 1000 further has positioning stations spaced apart in the second direction (eg Figure 2 I position) and loading station (such as Figure 2 The positioning mechanism 30 further includes a first translation assembly 32 connected to the placement platform 31. The first translation assembly 32 is used to drive the placement platform 31 to move in the second direction, so that the placement platform 31 can move to the positioning station to receive the batteries from the first conveying mechanism 20, and to the loading station for the second conveying mechanism 40 to pick up the batteries. This arrangement separates the first conveying mechanism 20 from the second conveying mechanism 40, reduces interference between the first conveying mechanism 20 and the second conveying mechanism 40, and facilitates safer loading of the second conveying mechanism 40.

[0047] Specifically, the first transport mechanism 20 is located above the first translation assembly 32 , and the second transport mechanism 40 is located on a side of the first translation assembly 32 away from the first transport mechanism 20 . The second transport mechanism 40 and the first transport mechanism 20 are spaced apart in the second direction.

[0048] Reference Figure 2 、 Figure 4 、 Figure 6 as well as Figure 8In the present application, the positioning station and the material picking station are spaced apart in the first direction, and the first conveying mechanism 20 includes a first material picking component 21 and a second translation component 22 and a first lifting component 23 connected to the first material picking component 21. The first material picking component 21 is used to pick up and place batteries, and the second translation component 22 is used to drive the first material picking component 21 to move in the first direction so that the first material picking component 21 can move to the positioning station and the loading station. The first lifting component 23 is used to drive the first material picking component 21 to move in a third direction (as shown in the direction in the figure) to transfer the battery from the material picking station to the positioning station, and the third direction is perpendicular to the first direction and the second direction; the second conveying mechanism 40 includes a second material picking component 41 and a manipulator 42 connected to the second material picking component 41. The second material picking component 41 is used to pick up and place batteries, and the manipulator 42 is used to drive the second material picking component 41 to move to the loading station to transfer the batteries in the placement table 31 to the vacuum sealing machine 2000.

[0049] Specifically, the second translation assembly 22 and the first lifting assembly 23 cooperate to drive the first picking assembly 21 to move the battery from the picking station to the positioning station and place the battery on the placement table 31. The first translation assembly 32 then drives the placement table 31 to move to the loading station. The manipulator 42 drives the second picking assembly 41 to remove the battery from the placement table 31 and load it into the vacuum sealer 2000 to complete automatic loading. The manipulator 42 can also unload the completed battery after the vacuum sealer 2000 completes battery packaging. In the above solution, the second translation assembly 22, the first lifting assembly 23, and the first translation assembly 32 can be linear motor modules or cylinders, which are not limited here.

[0050] It is worth mentioning that the loading device 1000 is equipped with a robot 42, which saves space and has a larger working coverage. It can automatically load and unload multiple vacuum sealing machines 2000 of the same type of process or different processes at the same time, so as to further improve production efficiency.

[0051] Exemplarily, two vacuum sealers 2000 are provided, and the two vacuum sealers 2000 are disposed on opposite sides of the second transport mechanism 40 in the first direction, that is, the second transport mechanism 40 is disposed between the two vacuum sealers 2000, so that the robot 42 can load materials into the two vacuum sealers 2000 separately. Optionally, the two vacuum sealers 2000 can be used for the first and second packaging of batteries, respectively, to optimize the production process. The robot 42 can transfer the completed batteries after the first packaging to the other vacuum sealer 2000 for the second packaging operation, thereby achieving a continuous production process and improving production efficiency.

[0052] Reference Figure 6In one embodiment, the first transport mechanism 20 includes a third translation assembly 24 connected to either the second translation assembly 22 or the first lifting assembly 23. The third translation assembly 24 is configured to drive the first picker assembly 21 to move in the second direction. This arrangement allows the first picker assembly 21 to be movable in the second direction relative to the third translation assembly 24. By switching the position of the first picker assembly 21, multiple batteries stacked side by side can be retrieved, increasing the number of batteries that can be stored for packaging. This allows for continuous retrieval during the loading and packaging process, reducing downtime and improving production efficiency. Specifically, the third translation assembly 24 is a pneumatic cylinder.

[0053] There are many ways to configure the first retrieving assembly 21 to be slidably connected to the third translation assembly 24. For example, a slide rail is provided on the third translation assembly 24, and the first retrieving assembly 21 is slidably connected to the slide rail. In another example, a groove extending in the first direction is provided on the third translation assembly 24, and a slider is provided on the first retrieving assembly 21 to fit within the groove.

[0054] Optionally, the first picking assembly 21 and the third translation assembly 24 can be connected by a magnetic connection or a threaded connection to maintain the relative position of the first picking assembly 21 after adjustment, thereby locking the position of the first picking assembly 21. For example, a through hole is provided on the first picking member 212, and a plurality of threaded holes corresponding to the through holes are provided on the third translation assembly 24. After screws are inserted into the through holes, they are threaded into the threaded holes to achieve the locking operation.

[0055] Reference Figure 4 and Figure 6 In one embodiment, two placement platforms 31 are provided, spaced apart in the second direction. Each placement platform 31 is equipped with a first positioning assembly 312 and a second positioning assembly 313. The first transport mechanism 20 is used to transfer two batteries from the retrieving station to their respective placement platforms 31. The first transport mechanism 20 includes two first retrieving assemblies 21, which are arranged opposite each other in the second direction. The two placement platforms 31 correspond one-to-one with the two first retrieving assemblies 21. This arrangement increases the number of batteries that the loading device 1000 can transport in a single load, allowing for more batteries to be transported at once, thereby improving production efficiency.

[0056] Optionally, two second picking assemblies 41 are also provided. At the loading station, the relative position between the two second picking assemblies 41 is consistent with the relative position between the two placement tables 31, so as to synchronously pick up two batteries for loading.

[0057] Reference Figure 6 and Figure 7In one embodiment, the first picking assembly 21 includes an adjustment plate 211 and a first picking member 212. The adjustment plate 211 is connected to the third translation assembly 24. The adjustment plate 211 is provided with a strip hole 211a extending in the first direction. The first picking member 212 includes a threaded rod 212a and two locking seats 213b. The threaded rod 212a is provided in the strip hole 211a. The two locking seats 213b are threadedly connected to the threaded rod 212a. The adjustment plate 211 is clamped between the two locking seats 213b. With this arrangement, the first picking member 212 can move relative to the adjustment plate 211 in the third direction and the second direction, that is, the first picking member 212 can be adjusted in the height and width directions so that the first picking member 212 can be in the correct position to pick up materials, and effectively prevent the first picking member 212 from being improperly positioned when picking up and placing materials, thereby causing damage to the battery.

[0058] Specifically, by loosening the locking seat 213b, the threaded rod 212a can be moved relative to the strip-shaped hole 211a, thereby adjusting the width. At the same time, by adjusting the position of the locking seat 213b on the threaded rod 212a, the position of the threaded rod 212a in the third direction relative to the adjustment plate 211 can be changed to achieve height adjustment.

[0059] The first picking member 212 can pick up batteries by clamping or vacuum suction, without limitation. For example, the first picking member 212 further includes a suction cup 213c. The threaded rod 212a is hollow, and the suction cup 213c is mounted on the threaded rod 212a and communicates with the interior of the threaded rod 212a. This allows the suction cup 213c to pick up the batteries, ensuring greater safety and preventing damage.

[0060] Specifically, the other end of the threaded rod 212a away from the suction cup 213c is connected to a negative pressure device, which is used to generate negative pressure on the suction cup 213c so that the suction cup 213c can generate suction to absorb the battery.

[0061] Optionally, a plurality of strip holes 211a are provided on the adjustment plate 211, and a plurality of first picking members 212 are provided. The plurality of first picking members 212 are respectively installed in the corresponding strip holes 211a to improve the stability of picking up the battery. In addition, the suction positions of the plurality of first picking members 212 on the battery can be adjusted to make the battery more balanced when subjected to force.

[0062] Similarly, refer to Figure 8 In this application, the second material taking component 41 is set up in the same way as the first material taking component 21, and will not be repeated here.

[0063] Reference Figure 1 and Figure 3In one embodiment, the loading device 1000 further includes a storage mechanism 50, which is mounted on the frame 10 and located at the material retrieving station. The storage mechanism 50 includes a lifting seat 51 and a second lifting assembly 52 connected to the lifting seat 51. The lifting seat 51 is used to carry a plurality of stacked material trays, on which batteries to be packaged are placed. The second lifting assembly 52 is used to drive the lifting seat 51 to move in a third direction, that is, to drive the material trays to the material retrieving station to feed the first material retrieving assembly 21. With this arrangement, the loading device 1000 can store more batteries to be packaged by having the lifting seat 51 carry the stacked material trays, thereby reducing downtime caused by insufficient materials, reducing the number of manual refills, and improving the continuity and efficiency of the production line.

[0064] Specifically, the second lifting component 52 can be a linear motor module, which drives the lifting seat 51 to move the stacked top material tray to the material picking station so that the first material picking component 21 can pick up the material. Moreover, when the material tray is empty, the first material picking component 21 can transfer the empty material tray to prepare for picking up the material from the lower material tray.

[0065] Further, refer to Figure 1 、 Figure 3 as well as Figure 6 In one embodiment, the loading device 1000 is further provided with a recovery station, which is located within the travel range of the first transport mechanism 20. The first transport mechanism 20 also includes a third retrieving assembly 25, which is connected to the second translation assembly 22 and is located to one side of the first retrieving assembly 21 in the first direction. The third retrieving assembly 25 is used to transfer empty trays at the retrieving station to the recovery station. In this way, by separately providing the third retrieving assembly 25 to handle empty trays, the operation process of the entire loading device 1000 can be optimized, efficiency can be improved, and the level of automation can be enhanced. In addition, the empty trays can be stored in an orderly manner at the recovery station, making it more convenient for staff to collect them in a unified manner. Specifically, the retrieving station, positioning station, and recovery station are arranged in sequence in the first direction. The frame 10 is also provided with a storage space 11, which is located at the recovery station and is used to receive empty trays picked up by the third retrieving assembly 25.

[0066] Furthermore, the third material picking component 25 includes a third material picking part 251 and a third lifting component 252. The third lifting component 252 is connected to the third material picking part 251. The third lifting component 252 can be a cylinder, which is used to drive the third material picking part 251 to move in the third direction, that is, to adjust the height of the third material picking part 251 so that the third material picking part 251 and the first material picking part 212 are misaligned in the third direction. In this way, the action of the third lifting component 252 can make the third material picking part 251 and the second material picking component 41 misaligned, avoiding interference with the material picking of the second material picking component 41, and after the second material picking component 41 picks up the battery, the third material picking part 251 can also immediately pick up the empty pallet and transport it synchronously through the second translation component 22, thereby reducing the round-trip time and improving production efficiency.

[0067] In this embodiment, the configuration of the third material-picking component 251 may be consistent with that of the second material-picking component 41 , which will not be described in detail here.

[0068] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
