Description

Technical Field

[0001] This utility model belongs to the field of battery negative pressure formation technology, specifically relating to a secondary positioning mechanism for new energy negative pressure formation. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, in the production process of new energy batteries (such as lithium batteries), there is an essential formation process. Existing technologies mostly involve placing the battery cell on a tray, moving the tray or probe assembly unit up and down, so that the probe contacts the battery to form a charging and discharging circuit for battery formation. At the same time, a vacuum structure evacuates the battery through the battery's liquid injection hole.

[0004] However, because the battery cells will have a certain displacement in the tray, the vacuum structure and the liquid injection hole may not be able to fit tightly, resulting in the negative pressure vacuum degree not meeting the requirements and causing a vacuum leakage alarm. Personnel need to enter the formation chamber to handle the problem and manually straighten the battery cells, which is time-consuming and laborious. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a secondary positioning mechanism for negative pressure formation of new energy. By setting positioning pins and positioning holes, the tray is first positioned, thereby enabling the battery cells to correspond one-to-one with the working components. By setting a clamping assembly, when the working components come into contact with the battery cells, the clamping assembly performs secondary positioning of the battery cells, ensuring a tight connection between the battery cells and the working components, and enabling smooth negative pressure formation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A secondary positioning mechanism for negative pressure formation of new energy includes a negative pressure formation chamber, which is a rectangular open frame structure with a bottom plate; multiple sets of working components are arranged at intervals between the short sides of the top of the negative pressure formation chamber.

[0008] A push-lock cylinder is fixed on each of the two long sides of the top of the negative pressure formation chamber, and a clamping assembly is connected to the output end of each push-lock cylinder; two guide bars are fixedly installed on the bottom plate of the negative pressure formation chamber, and a stop block is fixedly installed at one end of the guide bar, with a sensor installed on the side of the stop block facing the guide bar.

[0009] A support plate is provided between the two guide bars, and multiple positioning pins are provided on the support plate;

[0010] The tray is placed into the negative pressure formation chamber along the top of the guide bar, and multiple cells are placed in the tray at intervals. Multiple positioning holes are provided at the bottom of the tray.

[0011] When the tray reaches the stop, the locating pin can align with the locating hole.

[0012] Preferably, the working components include a positive electrode probe, a negative pressure suction cup, and a negative electrode probe.

[0013] Preferably, the working component is arranged on three long plates, which are bolted together between the short sides of the top of the negative pressure formation chamber. The negative pressure suction cup is arranged on the middle long plate, and positive or negative probes are arranged on the other two long plates.

[0014] Preferably, multiple guide blocks are provided on each side of the two guide bars that are far apart from each other, and the tray is constrained between the blocks and the guide blocks.

[0015] Preferably, the battery cell includes a positive terminal, a negative terminal, and an injection nozzle.

[0016] Preferably, the distance between the positive electrode probe, negative electrode probe, and negative pressure suction cup on the same set of working components is the same as the distance between the positive electrode post, negative electrode post, and liquid injection nozzle on the same battery cell.

[0017] Preferably, the spacing between the working components is equal to the spacing between the positive electrode probes or negative electrode probes or negative pressure chucks on adjacent cells.

[0018] Preferably, the clamping assembly includes a clamping vertical plate connected to the push-lock cylinder, a clamping horizontal plate is vertically fixedly connected to the clamping vertical plate, and a plurality of battery cell grooves are spaced apart on the clamping horizontal plate, the spacing between the battery cell grooves being the same as the spacing between the battery cells on the tray.

[0019] Preferably, the number of battery cells and battery cell grooves is the same as the number of working components, and the number of positioning holes and positioning pins is the same.

[0020] Preferably, the bottom of the pallet is connected to the output end of the lifting cylinder. There are two lifting cylinders, which are respectively installed at the bottom of both ends of the pallet. The lifting cylinders are fixedly installed at the bottom of the negative pressure formation chamber bottom plate.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are:

[0022] This invention uses positioning pins and holes to first position the tray, ensuring a one-to-one correspondence between the battery cells and the working components. By using a clamping assembly, when the working components contact the battery cells, the clamping assembly performs a second positioning, guaranteeing a tight fit between the battery cells and the working components. This allows for smooth negative pressure formation, preventing vacuum leakage alarms caused by insufficient negative pressure vacuum. Furthermore, it eliminates the need for personnel to enter the formation chamber to properly position the battery cells, saving time and effort. Attached Figure Description

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a secondary positioning mechanism for negative pressure formation of new energy sources, such as... Figure 1 As shown, the system includes a negative pressure formation chamber, which is a rectangular open frame structure with a base plate. Three long plates are bolted together along the short sides of the top of the chamber. Multiple sets of working components are mounted on these three long plates at equal intervals. Each set of working components includes a positive electrode probe 20, a negative pressure suction cup 30, and a negative electrode probe 40. It is understood that the spacing between the positive electrode probe 20, the negative pressure suction cup 30, and the negative electrode probe 40 can be adjusted by adjusting the distance between the three long plates.

[0031] In this embodiment, four sets of working components are provided. Four negative pressure suction cups 30 are provided on the middle long plate, and the spacing between the negative pressure suction cups 30 is equal. Positive electrode probes 20 and negative electrode probes 40 are provided on the other two long plates respectively. It can be understood that the number and position of the positive electrode probes 20 and negative electrode probes 40 correspond to the negative pressure suction cups 30, and are used to form the battery cells 120 placed on the tray 110.

[0032] like Figure 1 As shown, a push-lock cylinder is fixed on each of the two long sides of the top of the negative pressure formation chamber. The output ends of the two push-lock cylinders are connected to a clamping assembly; namely, the first push-lock cylinder 10 and the second push-lock cylinder 70. The first push-lock cylinder 10 is connected to the first clamping assembly 50, and the second push-lock cylinder 70 is connected to the second clamping assembly 60. The clamping assemblies are all made of POM material.

[0033] like Figure 1 As shown, in this embodiment, two guide bars 90 are fixedly installed on both sides of the midline of the short side of the negative pressure formation chamber bottom plate. Multiple guide blocks 80 are installed on each side of the two guide bars 90 that are far apart from each other. In this embodiment, there are two guide blocks 80 on each side, and the guide blocks 80 are fixedly connected to the negative pressure formation chamber bottom plate. Figure 1 As shown, a stop 100 is fixedly installed at one end of the guide bar 90. It should be noted that a sensor is installed on the side of the stop 100 facing the guide bar 90.

[0034] like Figure 1 , Figure 2 As shown, the tray 110 is placed above the guide bar 90 and between the guide block 80 and the stop block 100. The guide bar 90 supports the tray 110 and facilitates its placement into the negative pressure formation chamber. The guide block 80 restricts the movement of the tray 110 to its sides, preventing it from veering off course and providing a guiding function. The stop block 100 prevents the tray 110 from continuously moving forward out of its designated position as it is placed along the guide bar 90 into the negative pressure formation chamber. Furthermore, since a sensor is located on the side of the stop block 100 facing the guide bar 90, when the tray 110 contacts the stop block 100, the sensor detects that the tray 110 has reached the designated position and issues a prompt, such as "Tray in place," facilitating further operations by the staff. Understandably, the sensor uses existing mechanical contact alarm technology, which typically consists of a mechanical switch (such as a micro switch) and an alarm module (speaker). When the tray 110 touches the sensor (mechanical contact alarm), the mechanical switch (micro switch) is triggered, and the alarm module (speaker) emits a warning sound.

[0035] In this embodiment, four battery cells 120 are placed in the tray 110 at a set interval, and the bottom of the tray 110 is provided with multiple positioning holes; in this embodiment, two positioning holes are provided at the center line of the bottom of the tray 110; it should be noted that this embodiment does not improve the interior of the tray 110, so the tray 110 will not be described in detail here.

[0036] like Figure 3As shown, the battery cell 120 includes a positive terminal 121, a negative terminal 123, and an injection nozzle 122. It can be understood that on the same battery cell, the spacing between the positive probe 20, the negative probe 40, and the negative pressure suction cup 30 is consistent with the spacing between the positive terminal 121, the negative terminal 123, and the injection nozzle 122, thus ensuring a one-to-one correspondence between the negative pressure suction cup 30 and the injection nozzle 122, and between the positive terminal 121 and the positive probe 20, the negative terminal 123, and the negative probe 40. It can also be understood that when the tray 110 carries the battery cell 120 upwards to the bottom of the working assembly, each set of working components can correspond to each battery cell.

[0037] like Figure 2 As shown, a support plate 140 is provided between two guide bars 90 on the bottom plate of the negative pressure forming chamber. Multiple positioning pins 141 are located at the center line of the support plate 140; in this embodiment, there are two positioning pins. When the pallet 110 reaches the stop block 100, the positioning pins 141 align with the positioning holes on the bottom of the pallet 110, thereby positioning the pallet 110. The bottom of the support plate 140 is connected to the output ends of multiple lifting cylinders 130. In this embodiment, two lifting cylinders 130 are provided, respectively located at the bottom of both ends of the support plate, thereby ensuring the stability of the support plate 140 in supporting the upward movement of the pallet 110.

[0038] Understandably, the bottom plate of the negative pressure formation chamber has an output hole for the output end of the lifting cylinder 130 to pass through, and the lifting cylinder 130 is fixedly connected to the bottom of the bottom plate of the negative pressure formation chamber.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, both the first clamping assembly 50 and the second clamping assembly 60 include a clamping vertical plate connected to the push-lock cylinder. The clamping vertical plate is fixedly connected to the clamping horizontal plate, and the clamping vertical plate and the clamping horizontal plate are perpendicular to each other. The clamping horizontal plate is provided with multiple battery cell grooves, and the spacing between the battery cell grooves is the same as the spacing between the battery cells 120 on the tray 110. Furthermore, when the tray 110 contacts the stop block 100, as... Figure 3 As shown in the top view, the positions of the battery cell 120 and the battery cell groove correspond one-to-one; when the tray contacts the stop block, the positions of the battery cell, the battery cell groove, and the working component correspond one-to-one.

[0040] Understandably, the positions of the first and second push-lock cylinders correspond, so the positions of the first and second clamping assemblies also correspond. When the two clamping assemblies approach each other under the push of the two push-lock cylinders, the cell grooves on the two clamping assemblies can firmly clamp the corresponding cells, thereby achieving secondary positioning of the cell position. This ensures that the negative pressure suction cup 30 matches the injection nozzle 122, the positive electrode post 121 matches the positive probe 20, and the negative electrode post 123 matches the negative probe 40, making the negative pressure suction cup 30 and the injection nozzle 122 tightly connected. This prevents the position of the negative pressure suction cup 30 and the injection nozzle 122, the positive electrode post 121 and the positive probe 20, and the negative electrode post 123 matches the negative probe 40 during negative pressure formation. If the negative pressure suction cup and the injection nozzle cannot be tightly connected, the negative pressure vacuum degree will not meet the requirements, causing a vacuum leak alarm. This would require personnel to enter the formation chamber for handling, and manually straightening the cell would be time-consuming and laborious.

[0041] Working principle:

[0042] A stacker crane is used to transfer a pallet 110 containing battery cells 120 from the logistics line to the negative pressure formation warehouse.

[0043] The tray 110 is restricted on both sides by guide blocks 80, and then sent into the negative pressure formation chamber along guide bar 90. The front side of the tray 110 contacts the stop block 100. The sensor detects that the tray 110 is in place and issues a prompt sound to facilitate the next step of operation.

[0044] Next, the output end of the lifting cylinder 130 extends and drives the pallet 140 to rise, so that the positioning pin 141 overlaps with the positioning hole under the pallet 110 and is inserted to fix the position of the pallet 110.

[0045] The lifting cylinder 130 continuously drives the tray 110 upward until the positive terminal post 121 of the battery cell 120 contacts the positive probe 20, the negative terminal post 123 contacts the negative probe 40, and the negative pressure suction cup 30 contacts the injection nozzle 122.

[0046] Next, the first push-lock cylinder 10 and the second push-lock cylinder 70 are extended simultaneously, driving the first clamping assembly 50 and the second clamping assembly 60 to clamp the battery cell 120 and perform secondary positioning of the battery cell 120.

[0047] Finally, the battery cells undergo negative voltage formation.

[0048] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
