Description

Technical Field

[0001] This utility model belongs to the technical field of battery manufacturing, specifically, it relates to a battery double-sealing limiting clamp. Background Technology

[0002] During battery formation, a certain amount of gas is usually generated. To mitigate the adverse effects of this gas, an air bladder is often pre-installed on one side of the battery casing and cell housing. After the formation process is completed, the air bladder is deflated and removed during the secondary sealing process. Currently, the air bladder is typically operated using a secondary sealing machine.

[0003] The secondary sealing machine used in related technologies includes a lower sealing assembly and an upper sealing assembly that slides towards or away from the lower sealing assembly. The lower sealing assembly includes a worktable with a battery placement plate on its top surface. A lower sealing head is located on one side of the battery placement plate, and a venting pad is located on the side of the lower sealing head away from the battery placement plate. The venting pad has multiple venting holes. The upper sealing assembly includes an upper sealing head corresponding to the lower sealing head, a piercing blade corresponding to the venting holes, and a pressure plate corresponding to the battery placement plate. The upper sealing head, piercing blade, and pressure plate are all independently movable. During use, the pressure plate and the battery placement plate work together to clamp the battery, and the venting and secondary sealing operations are completed through the cooperation of the upper and lower sealing heads, piercing blade, and venting holes.

[0004] However, during the manufacturing process, it was found that some batteries were tilted. When the cell and the end cap did not intersect, it was easy to produce defective products with excessively large unsealed areas. When the cell and the end cap intersected, the end cap directly contacted the cell, which created certain safety hazards.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a battery double-sealing limiting clamp.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A battery double-sealed limiting clamp includes a battery placement plate and a push plate for driving the battery to move. The push plate is slidably disposed on the side of the battery placement plate for placing the battery. The sliding path of the push plate protrudes from the side wall of the battery placement plate, and a support member for supporting the push plate is provided on one side of the protruding end of the sliding path.

[0009] Preferably, the support member is slidably disposed relative to the push plate, the support member is plate-shaped, and the side of the support member near the push plate is not lower than the battery placement plate.

[0010] Preferably, the support member is slidably disposed relative to the push plate, and the support member is rod-shaped.

[0011] Preferably, the support member is connected to the push plate, and the support member and the push plate slide synchronously.

[0012] Preferably, a push rod is connected to the side of the push plate away from the battery placement plate, the support member is disposed between the battery placement plate and the push rod, and the side of the push rod facing the push plate is flush with the side of the support member facing the push plate. A drive member for driving the push rod to slide is also connected to the push rod.

[0013] Preferably, when the support member is connected to the push plate, the support member is connected to the push rod.

[0014] Preferably, limiting members are provided on both sides of the sliding path of the push plate, and the position of the limiting members relative to the push plate is fixed or adjustable.

[0015] Preferably, the side of the battery placement plate away from the support member is provided with a heat insulation layer.

[0016] Preferably, the push plate is inclined on the side near the insulation layer, and the inclined surface is tilted toward the battery placement plate.

[0017] Preferably, the push plate is also provided with a through hole.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0019] By setting up a push plate, before the second sealing, the push plate moves the battery to a suitable position, which facilitates the second sealing and venting operations. During this process, the support component provides a certain degree of support for the push plate, effectively reducing the occurrence of the push plate sagging, thereby effectively ensuring the limiting effect of the push plate on the battery.

[0020] Furthermore, by connecting the support member with the push plate and the drive member, the support member and the push plate can move synchronously. This increases or decreases the stability of the push plate during its movement, reduces the wear rate of the push plate, and extends the service life of the device. Attached Figure Description

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] A battery double-seal limiting clamp, as shown in the reference Figure 1 and Figure 2The battery placement plate 1 includes a battery placement surface 101 for placing batteries and a mounting surface 102 for mounting the battery placement plate 1. A support member 2 is separately disposed on one side of the battery placement plate 1. In this embodiment, the support member 2 is plate-shaped, and one of its planes is flush with the battery placement surface 101. In other embodiments, the support member 2 may protrude. A push plate 3 is slidably disposed on one side of the battery placement surface 101 of the battery placement plate 1. The push plate 3 abuts against the side wall of the support member 2 and slides along the surface of the support member 2. During the sliding process of the push plate 3, the relative position between the support member 2 and the battery placement plate 1 remains unchanged.

[0033] Reference Figure 1 A first mounting hole 4 is provided on the side of the push plate 3 away from the battery placement plate 1. A push rod 5 is connected and installed through the first mounting hole 4 and a bolt. During normal use of the push plate 3, the support member 2 is disposed between the push rod 5 and the battery placement plate 1. The push rod 5 is connected to the driving end of the driving member 6 and moves the push plate 3 under the action of the driving member 6. In this embodiment, the driving member 6 is a cylinder, and the push rod 5 is T-shaped. The belly of the push rod 5 is connected to the driving end of the driving member 6 and slides under the driving action of the driving member 6. During this process, the push plate 3 slides towards or away from the battery placement plate 1 under the support and guidance of the surface of the support member 2, and partially covers the battery placement plate 1 to facilitate the limiting of the battery.

[0034] Reference Figure 1 A heat insulation layer 7 is provided on the side of the battery placement plate 1 away from the support member 2. When installing and using the clamp, the heat insulation layer 7 should be placed close to the end cap. With this arrangement, when the push plate 3 pushes the battery to move, the heat insulation layer 7 isolates the battery side wall and the end cap, effectively reducing the occurrence of the battery contacting the end cap under the action of the push plate 3, and reducing safety hazards during use.

[0035] Reference Figure 2To further improve the battery positioning effect, both ends of the battery placement plate 1 protrude from the sidewalls of the connecting plate 14, and a connecting plate 8 is connected to the side of the protruding end facing the support plate. A limiting member 9 is also connected to the battery placement surface 101. In this embodiment, the limiting member 9 is plate-shaped, its length is parallel to the sliding path of the push plate 3, and its length is the sum of the lengths of the connecting plate 8 and the battery placement plate 1. The limiting member 9 is located on both sides of the sliding track of the push plate 3. To facilitate the positioning of batteries of various specifications, multiple waist-shaped second mounting holes 10 are arrayed on the limiting member 9, and corresponding waist-shaped third mounting holes 11 are provided on the connecting plate 8 and the battery placement plate 1. By adjusting the relative positions of the second mounting holes 10 and the third mounting holes 11, the installation position of the limiting member 9 can be adjusted, thereby adjusting the distance between the limiting members 9. This facilitates guiding and limiting the sliding path of batteries of different specifications as they move with the push plate 3, effectively improving the applicability of the device.

[0036] Reference Figure 2 To further reduce wear caused by friction between the push plate 3 and the support member 2 during the sliding process, a through hole 12 is provided through the side wall of the push plate 3. The presence of the through hole 12 effectively reduces the mass of the push plate 3, thereby reducing the friction between the push plate 3 and the support member 2, thus improving the wear of the parts, increasing the accuracy of battery positioning, and extending the service life of the device.

[0037] The principle of this embodiment is as follows: during the secondary sealing and venting process of the battery, the battery must first be placed on the battery placement surface 101. Then, the push rod 5 and the push plate 3 are moved by the drive member 6. During the movement of the push plate 3, a pushing force is applied to the battery. During this process, the support member 2 provides support for the push plate 3, which improves the stability of the push plate 3 during its movement. At the same time, the limiting member 9 also has a certain guiding and limiting effect on the battery, which corrects the battery position. When the battery moves to contact the heat insulation layer 7, the limiting member 9 and the heat insulation layer 7 interact to clamp the battery, thereby limiting the battery position, reducing the defect rate, and improving safety.

[0038] Example 2

[0039] A battery double-seal limiting clamp, as shown in the reference Figure 3The difference from Embodiment 1 is that the support member 2 consists of multiple support rods arranged in a spaced array. The support rods are offset from the through holes 12. A T-shaped mounting base is fixedly installed on the side of the support member 2 away from the push plate 3. The support member 2 can be installed on the corresponding workbench by means of the mounting base and bolts. In addition, in other embodiments, the side of the push plate 3 facing the battery placement plate 1 can be set as an inclined surface. When the push plate 3 or the support member 2 has a certain amount of wear, causing the end of the push plate 3 to droop, the inclined surface of the push plate 3 contacts the battery placement plate 1 and has a certain guiding effect on the push plate 3, reducing the interference between the push plate 3 and the battery placement plate 1 and ensuring the normal use of the device.

[0040] Example 3

[0041] A battery double-seal limiting clamp, as shown in the reference Figure 4 The difference from Embodiment 2 is that the support member 2 further includes a support rod 13 disposed at the top of the support rod. The length direction of the support rod 13 is parallel to the plane where the push plate 3 is located. The side of the support rod 13 away from the push plate 3 is connected to the ends of multiple support rods, and the side of the support rod 13 near the push plate 3 is flush with the side of the push rod 5 near the push plate 3. By supporting the push plate 3 with the support rod 13, the contact area between the push plate 3 and the support rod 13 is effectively increased, thus improving the support effect.

[0042] Example 4

[0043] A battery double-seal limiting clamp, as shown in the reference Figure 5 The difference from Embodiment 3 is that one end of the support rod is connected to the push plate 3, and the other end is connected to a connecting plate 14. The end of the connecting plate 14 away from the support rod is connected to the push rod 5, and moves synchronously with the push plate 3 under the action of the push rod 5. Connecting the support rod and the push plate 3 can effectively reduce the wear of the device and extend the service life of the device.
