Description

Technical Field

[0001] This utility model relates to a battery electrode group insertion clamp, belonging to the field of battery manufacturing technology. Background Technology

[0002] During battery manufacturing, after the positive and negative plates are assembled to form an electrode group, the distance between the plates is relatively large, and the electrode group is relatively loose. It needs to be sorted, squeezed, and clamped before it can be placed into the battery case. In this automated operation, it is necessary to carefully control the squeezing force during squeezing to avoid over-clamping. When releasing the clamp, it is also necessary to avoid releasing it too much or too little, so as to prevent the electrode group from not being able to be placed into the clamp, which would increase costs, reduce efficiency, or even affect quality.

[0003] Currently, there are related clamps, such as the utility model patent application CN202323184574.2 entitled "A Battery Electrode Group Insertion Clamp," which uses a limiting plate set on the outer edge of the movable plate to control the movement distance of the movable plate. Another utility model patent, CN201821459523.2, entitled "Electrode Group Insertion Clamp," applied for by Zhejiang Chuangwei Intelligent Equipment Co., Ltd., uses a linkage member set on the outer edge of the partition to control the movement distance of the partition. The above solutions only mention the structure for clamping the electrode group, but do not describe in detail how to open the clamp after the electrode group is inserted to receive the next electrode group. Therefore, improvements are needed. Utility Model Content

[0004] This utility model addresses the problem that current battery electrode insertion clamps do not fully disclose how to properly open the clamp after the electrode group is inserted into the slot. It proposes a battery electrode insertion clamp that can accurately control the clamping and opening strokes.

[0005] The technical means adopted by this utility model to solve the above problems is as follows: a battery terminal group insertion clamp, including a support frame and a power component fixed to the support frame, a clamping plate mechanism disposed on the support frame to clamp the terminal group, the clamping plate mechanism including a movable plate connected to the moving end of the power component, a clamping plate driven by the power component to reciprocate, a limiting plate to limit the return distance of the clamping plate, and a guide group to transmit the movement of the power component to the clamping plate and drive the clamping plate to return, wherein the clamping plate and the movable plate are arranged parallel to each other in the support frame, the limiting plate is disposed at the edge of the clamping plate, the guide group is arranged perpendicular to the clamping plate and the movable plate and connects the clamping plate and the movable plate, the guide group including a guide post fixed relative to the support frame, a sleeve sleeved outside the guide post and slidable along the guide post, and a limiting cylinder sleeved outside the sleeve and slidable along the sleeve, and the sleeve is provided with a buckle that can hook the limiting cylinder. The clamping and loosening range of the clamping plate is controlled by the cooperation of the limiting plate and the guide group to avoid the range being too large or too small.

[0006] Furthermore, the limiting plate is fixed to the support frame and extends into the end of the clamping plate. When the clamping plate retracts, the limiting plate contacts the clamping plate and forms a blockage, preventing the clamping plate from retracting too much.

[0007] Furthermore, both the guide post and the sleeve pass through the clamping plate, the end of the limiting sleeve can abut against the side wall of the clamping plate, and both ends of the guide post are fixed to the support frame.

[0008] Furthermore, the sleeve has a structure that is larger at one end and smaller at the other, with the smaller end close to the power component. The outer wall of the sleeve forms a buckle at the transition point from the larger end to the smaller end, which can hook onto the limiting cylinder. When the power component drives the clamping plate to move backward, the buckle hooks onto the limiting cylinder, and the limiting cylinder in turn presses against the side wall of the clamping plate, causing the clamping plate to move backward synchronously.

[0009] Furthermore, the clamping mechanism also includes a fixed plate that is fixed relative to the support frame, and the clamping plate is located between the fixed plate and the movable plate; one end of the sleeve is close to the fixed plate, and the other end extends to the movable plate; there are multiple sets of limiting cylinders, which are located between the fixed plate and the clamping plate, and between the clamping plate and the movable plate, respectively. When there are multiple clamping plates, limiting cylinders are also provided between the clamping plates.

[0010] Furthermore, one end of the sleeve extends through the movable plate and can slide along it. A locking nut is provided at the end near the power component after passing through the movable plate. This prevents the sleeve from sliding out of the movable plate when it advances.

[0011] Furthermore, a blocking ring is provided at the end of the limiting cylinder closest to the fixed plate away from the fixed plate. The buckle at the end of the sleeve closest to the fixed plate cooperates with the blocking ring to pull the limiting cylinder to move.

[0012] Furthermore, two clamping plates are provided between the fixed plate and the movable plate, and the limiting cylinder between the two clamping plates is divided into two independent ones. The inner diameter of the limiting cylinder closer to the fixed plate is larger than the inner diameter of the limiting cylinder farther from the fixed plate, and the sleeve also has a buckle in this range. The outer diameter of the buckle is larger than the inner diameter of the limiting cylinder farther from the fixed plate but slightly smaller than the inner diameter of the limiting cylinder closer to the fixed plate.

[0013] Furthermore, the fixing plate is located in the middle of the support frame. Limiting plates and guide groups are provided on both sides of the fixing plate. The guide groups on both sides of the fixing plate share a guide post. The guide post passes through the fixing plate and is connected to the support frame at both ends. The two sleeves face the fixing plate with their larger ends.

[0014] Furthermore, the support frame is equipped with power components and movable plates in both its transverse and longitudinal directions, clamping the pole group from both directions.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses a limiting plate and a guide group to guide and control the clamping or loosening of the clamping plate, making the movement of the clamping plate smoother and the structure simpler.

[0017] 2. This utility model, by setting a limiting sleeve outside the sleeve, prevents the clamping plate from advancing too far when the power component pushes it forward, thus avoiding damage to the electrode group. Furthermore, by setting an inverted buckle on the sleeve, when the power component pulls the clamping plate backward, the inverted buckle can drive the sleeve backward together, thereby pushing the clamping plate backward synchronously; and by setting a limiting plate, it also prevents the clamping plate from retreating too far.

[0030] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0031] A battery terminal group insertion clamp, such as Figure 1 As shown, this embodiment produces a 1*6 series battery with six electrode groups arranged in a single row along the longitudinal direction. The entire assembly includes a support frame 100, which in this embodiment is a square structure. At each of the longitudinal ends of the support frame 100, there is a cylinder as a power component 1, and at each of the transverse ends, there are two cylinders as power components 1. The support frame 100 contains four movable plates 110, one at each of the longitudinal and transverse ends. The four movable plates 110 also form a square structure, constituting the accommodating space for the electrode group 2. At each of the longitudinal ends, one movable plate 110 is connected to the movable end of one cylinder, while at each of the transverse ends, two cylinders are connected to one movable plate 110. It also includes a fixed plate 120, a clamping plate 130, a limiting plate 140, and a guide group 300. The fixed plate 120 is located in the middle position inside the support frame 100 and is fixedly connected to the support frame 100. There are four clamping plates 130, which are arranged in pairs between the fixed plate 120 and the movable plate 110. The movable plate 110 and the clamping plate 130, the clamping plates 130 and the clamping plates 130, and the clamping plates 130 and the fixed plate 120 form a pressing space for three pole groups 2. There is one set on each side of the fixed plate 120, which presses the six pole groups 2 longitudinally at one time.

[0032] like Figure 1 , Figure 2 and Figure 5As shown, the support frame 100 is equipped with a guide assembly 300 to transmit the power of the cylinder, so as to push the clamping plate 130 forward to clamp the pole group 2 or push the clamping plate 130 back to reset the clamping plate 130. A limiting plate 140 is provided on the longitudinal side of the support frame 100 to ensure that the clamping plate 130 stops in a suitable position when it returns, ensuring that the distances between the fixed plate 120 and the clamping plate 130, between the clamping plates 130, and between the clamping plate 130 and the movable plate 110 are equal after reset, facilitating the insertion of the pole group 2 in the next round. The limiting plate 140 is fixed to the support frame 100 and extends into the end of the clamping plate 130. When the clamping plate 130 returns, the limiting plate 140 presses against the clamping plate 130 from behind, limiting the distance the clamping plate 130 returns.

[0033] Since the pole group 2 is generally rectangular, the movable plate 110, the fixed plate 120 and the clamping plate 130 are all designed to be rectangular.

[0034] like Figure 3 and Figure 4 As shown, the guide assembly 300 includes a guide post 310, a sleeve 320 fitted outside the guide post 310, and a limiting sleeve 330 fitted outside the sleeve 320. The guide assembly 300 has eight sets in total, symmetrically arranged in pairs at the four corners on both sides of the fixed plate 120. Each pair of sets shares one guide post 310. Therefore, the two ends of the guide post 310 are connected to the support frame 100, and pass sequentially through the movable plate 110, clamping plate 130, clamping plate 130, fixed plate 120, clamping plate 130, clamping plate 130, and movable plate 110. Two sleeves 320 are fitted onto one guide post 310 and located on both sides of the fixed plate 120. Each sleeve 320 passes through the movable plate 110 and clamping plate 130, as shown. Figure 2 As shown, after each sleeve 320 passes through the movable plate 110, a locking nut 340 is provided on the side of the movable plate 110 near the cylinder to lock the end of the sleeve 320, so as to prevent the sleeve 320 from falling off the movable plate 110. When the cylinder pulls the movable plate 110 back, it can bring the sleeve 320 back at the same time. The limiting cylinder 330 is positioned between the fixed plate 120 and the clamping plate 130, between the clamping plates 130 and 130, and between the clamping plate 130 and the movable plate 110. The height of the limiting cylinder 330 between the fixed plate 120 and the clamping plate 130, between the clamping plates 130 and 130, and between the clamping plate 130 and the movable plate 110 is equal to the thickness of the pole group 2 after it is clamped. When the cylinder pushes the movable plate 110 forward, the movable plate 110 pushes the limiting cylinder 330 in front of it forward. This limiting cylinder 330 then pushes the clamping plate 130 in front of it forward, and so on, until both ends of the limiting cylinder 330 are in contact with each plate, thus avoiding excessive compression of the pole group 2.

[0035] like Figures 6-9As shown, the sleeve 320 has a structure that is larger at one end and smaller at the other. The larger end is close to the fixed plate 120, and the smaller end is located at the movable plate 110. A stepped buckle 321 is formed at the transition from the larger end to the smaller end of the sleeve 320. In this embodiment, each sleeve 320 has two buckles 321. The first-level buckle 321 at the larger end is located between the fixed plate 120 and the clamping plate 130, and the smaller second-level buckle 321 is located between the clamping plates 130 and each other. Correspondingly, the first-level limiting sleeve 330 located between the fixed plate 120 and the clamping plate 130 has an inwardly protruding blocking ring 331 at the end furthest from the fixed plate 120. Figure 10 and Figure 11 As shown, the maximum outer diameter D1 at the first-stage inverted buckle 321 is smaller than the inner diameter d1 of the first-stage limiting cylinder 330 and larger than the minimum inner diameter d2 at the blocking ring 331. Thus, the first-stage inverted buckle 321 of the sleeve 320 can slide within the first-stage limiting cylinder 330, and when the sleeve 320 retracts, the first-stage limiting cylinder 330 can simultaneously push the clamping plate 130 near the fixed plate 120 to retract, increasing the distance between the fixed plate 120 and the clamping plate 130. Furthermore, as... Figure 5 As shown, when the clamping plate 130 moves back a certain distance, the limiting plate 140 fixed to the support frame 100 blocks the clamping plate 130 to prevent the distance between the fixing plate 120 and the clamping plate 130 from being too large.

[0036] At the same time, such as Figures 6-11 As shown, the limiting cylinders 330 located between the two clamping plates 130 are designed as two independent units: a first limiting cylinder 332 closer to the first limiting cylinder 330 and a second limiting cylinder 333 farther away from the first limiting cylinder 330. The inner diameter d2 of the first limiting cylinder 332 is equal to the minimum inner diameter d2 at the blocking ring 331 and greater than the inner diameter d3 of the second limiting cylinder 333. The outer diameter D2 of the second-stage buckle 321 of the sleeve 320 is less than d2 and greater than d3. Therefore, the second-stage buckle 321 can slide within the first limiting cylinder 332. When the sleeve 321 retracts, the second-stage buckle 321 can pull the second limiting cylinder 333 back together, thereby pulling the clamping plate 130 near the movable plate 110 back as well. Furthermore, as... Figure 5 As shown, when the clamping plate 130 retracts to a certain distance, the limiting plate 140 fixed to the support frame 100 blocks the clamping plate 130 to prevent the distance between the two clamping plates 130 from being too large. By dividing the limiting cylinder 330 between the two clamping plates 130 into limiting cylinder one 332 and limiting cylinder two 33, when the cylinder drives the movable plate 110 to move forward or backward, and thus drives the sleeve 320 to move forward or backward, the secondary inverted buckle 321 can freely pass through the clamping plate 130 near the fixed plate 120, ensuring that the stroke of the two clamping plates 130 is large enough to meet the operation requirements of clamping and loosening. Example 2

[0037] In this embodiment, a 2*3 series battery is produced. In this case, only one power component 1 is needed vertically, with one end of the support frame 100 directly used as the fixing plate 120. Only one sleeve 320 is fitted onto each guide post 310. Two clamping plates 130 are still provided between the fixing plate 120 and the movable plate 110. In the horizontal direction, two power components 1 can be arranged, one at each end, with a fixing plate 120 positioned in the middle. Each power component 1 at both ends is connected to a movable plate 110. The movable plate 110 and the fixing plate 120 form the placement space for the electrode group 2. In this direction, the clamping plates 130 are not required.

[0038] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
