Description

Technical Field

[0001] The utility model relates to the technical field of battery packaging, in particular to a polymer soft-pack battery testing bipolar ear mechanism and a packaging production line. Background Art

[0002] In recent years, with the rapid development of the new energy vehicle industry and the mobile electronic equipment industry, batteries have developed rapidly, especially soft-pack batteries, which are favored due to their good safety performance, light weight, high capacity, high energy density, low internal resistance, and flexible design. The market occupancy rate continues to increase, and it has broad market prospects.

[0003] As one of the core components of new energy vehicles, the battery module has very high requirements for its production process. As one of the important components of the battery module, it goes without saying that the packaging of the soft-pack battery cell also needs to ensure high quality and safety.

[0004] Existing polymer soft-pack battery packaging production lines, such as the Chinese patent document number CN217507415U, discloses a soft-pack battery packaging production line, including an inkjet printer, a pad printer, an automatic top sealing tape machine, an automatic side and bottom sealing tape machine, a laser welding machine, an automatic glue folding and shaping machine, an automatic peripheral tape machine, an automatic FPC folding machine, a full inspection jig, a battery comprehensive tester, a CCD and a code scanning device. The battery packaging line of the above technical solution can realize the automatic sealing of soft-pack power batteries, the welding of positive and negative pole ears and the inkjet marking. However, in this production line, the appearance of the battery cell is inspected after the positive and negative pole ears are welded to determine the defective products through direct observation by the workers' naked eyes. This method greatly increases the labor and labor costs, and the naked eye recognition efficiency is low. The human eye is prone to visual fatigue after long-term observation, and the probability of misrecognition is high, which in turn causes an increase in the defective rate. In addition, some production lines use CCD cameras for visual recognition detection. Although this detection method has high detection efficiency, it mainly detects whether there are problems with the battery packaging position and the appearance and strength of the solder joints. There is still a possibility of missing other defects. For example, when the tabs on the battery overlap, that is, double tabs appear, especially when the tabs overlap completely, it may be difficult to distinguish them at once through image vision, and the double tab phenomenon cannot be effectively intercepted, resulting in defective products flowing into subsequent processes, causing the defective rate to increase, resulting in unqualified products flowing to the client and causing customer complaints. Therefore, in order to solve the above problems, the utility model is derived. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0033] A polymer soft-pack battery test bipolar ear mechanism according to an embodiment of the utility model, see Figures 1 to 7 , including a frame 10, a contact test assembly 20 and a shaping mechanism 30. Among them, the frame 10 includes Figure 2 The plate-shaped first base 11 and two first columns 12 arranged opposite to each other and spaced apart on the first base 11 are shown. The contact test assembly 20 is arranged on the frame 10, specifically at the upper ends of the two first columns 12 and can be lifted and slid vertically relative to the frame 10. The contact test assembly 20 is used to descend and press against the tab of the soft-pack battery 70 to be tested and can test the thickness of the tab. The shaping mechanism 30 is arranged on one side of the frame 10, such as Figure 1 The shaping mechanism 30 is used to squeeze and shape the other three sides of the soft pack battery 70 to be tested except for the side with the pole ear welded. Specifically, Figures 2 to 7As shown, the shaping mechanism 30 includes a substrate 31, a support platform 32 and a shaping component 33. The support platform 32 is arranged on the side of the substrate 31 close to the frame 10, and is used to support and position the soft-pack battery 70 to be tested. The shaping component 33 is arranged on the substrate 31 and can move relative to the substrate 31 to move closer to or away from the support platform 32 on the substrate 31, and is used to squeeze and shape the side of the soft-pack battery 70 to be tested. The double-pole ear mechanism for testing the soft-pack battery 70 of the embodiment of the utility model is provided with a contact test component 20 that can move vertically relative to the frame 10. The contact test component 20 of the embodiment of the utility model has two, which correspond to the positive and negative poles of the soft-pack battery 70 to be tested. The thickness of the pole ear is detected by vertical displacement. When the pole ears overlap, the thickness of the two pole ears will be significantly greater than the thickness when there is only one pole ear, so the phenomenon of pole ear overlap can be accurately judged, ensuring the control of product quality during the production process, and reducing the safety hazards caused by product quality problems flowing to the client. In addition, the shaping mechanism 30 can not only shape the soft-pack battery 70 to be tested, but also support and position the soft-pack battery 70, so as to facilitate the contact testing component to detect the thickness of the tab.

[0034] Specifically, Figure 2 As shown, the contact test assembly 20 includes a vertical drive member 21 and a contact displacement sensor probe 22. The vertical drive member 21 is fixedly mounted on the first column 12 and can perform telescopic movement in the vertical direction. It can be selected as an existing conventional cylinder. The contact displacement sensor probe 22 is mounted on the driving end of the vertical drive member 21, specifically on the bottom end of the vertical drive member 21 as shown in the figure. The contact displacement sensor probe 22 is an existing conventional contact displacement sensor. The specific structure and working principle are not described or limited, and those skilled in the art can easily know and implement it.

[0035] like Figure 4 As shown, the support platform 32 of the embodiment of the utility model includes two parts, one part is a first support platform 32132 for supporting and positioning the body of the soft-pack battery 70, and the other part is a second support platform 32232 for positioning and supporting the positive and negative pole ears on one side of the body of the soft-pack battery 70 to be tested. The first support platform 32132 is directly fixed on the substrate 31 and partially exposed outside the side of the substrate 31 close to the frame 10, and the second support platform 32232 is installed on the side of the first support platform 32132 exposed outside the substrate 31, and the two parts are T-shaped. Interference between the support platform 32 and the frame 10 can be prevented. The two parts can be an integral structure, or they can be connected together by a detachable connection method such as welding, threaded connection, or bonding.

[0036] In the embodiment of the utility model, the shaping mechanism 30 is preferably movable. Figure 2 and Figure 3 As shown, the shaping mechanism 30 also includes a support frame 34 and a first displacement drive assembly 35. The support frame 34 is arranged at the bottom of the base plate 31, and includes a plate-shaped second base 341 and second columns 342 arranged at four corners of the second base 341. The tops of the second columns 342 are respectively fixedly connected to the base plate 31. The first displacement drive assembly 35 is connected to the support frame 34, and is used to drive the support frame 34 and drive the base plate 31 and the support platform 32 and the shaping assembly 33 on the base plate 31, that is, the entire shaping mechanism 30 to move closer to or away from the frame 10, that is, as shown in FIG. Figure 1 As shown in FIG. 1 , the first displacement drive assembly 35 is Figure 2 and Figure 3 As shown, it includes a first transverse driving member 351 and a first slider 352. The first transverse driving member 351 moves along the displacement direction of the shaping mechanism 30, that is, along the Figure 2 The first slider 352 is fixed to the bottom of the support frame 34, specifically the bottom of the second base 341. The first slider 352 is slidably matched with the first linear guide rail 40. The extension direction of the first linear guide rail 40 and the linear displacement direction of the shaping mechanism 30 are also as shown in FIG. Figure 1 The left and right directions shown are consistent, and the first linear guide rail 40 can be fixed on the ground.

[0037] For the shaping component 33, Figure 2 As shown, it includes a displacement direction along the shaping mechanism 30, that is, Figure 1 The lateral displacement shaping member 331 that performs linear displacement in the left and right directions as shown and the two displacement directions perpendicular to the shaping mechanism 30 are also shown as Figure 1The longitudinal displacement shaping member 332 shown in the figure performs linear displacement in the up and down directions, and the second displacement driving assembly 333 that drives the lateral displacement shaping member 331 and the longitudinal displacement shaping member 332 to perform linear displacement together. The lateral displacement shaping member 331 is arranged at the middle position of the substrate 31, and the two longitudinal displacement shaping members 332 are arranged at both sides of the substrate 31 and are symmetrically arranged with respect to the lateral displacement shaping member 331. Correspondingly, in order to facilitate the lateral displacement shaping member 331 and the longitudinal displacement shaping member 332 to perform linear displacement relative to the substrate 31 without causing interference with the substrate 31, the substrate 31 is provided with corresponding sliding grooves at the positions corresponding to the lateral displacement shaping member 331 and the two longitudinal displacement shaping members 332. For the convenience of description and distinction, the sliding groove corresponding to the lateral displacement shaping member 331 is the lateral sliding groove 311, and the sliding groove corresponding to the longitudinal displacement shaping member 332 is the longitudinal sliding groove 312. Similarly, the transverse slot 311 is opened in the middle of the base plate 31, and the longitudinal slots 312 are opened on both sides of the base plate 31 and are symmetrical about the transverse slot 311. Preferably, the number of the transverse slots 311 is two and they are arranged in parallel at intervals, and the number of the longitudinal slots 312 on either side is also two and they are arranged in parallel at intervals.

[0038] More specifically, Figure 5 As shown, the lateral displacement shaping member 331 includes a lateral shaping frame 3311, a lateral shaping block 3312 and a second slider 3313. The lateral shaping frame 3311 includes a horizontal plate-shaped first bottom plate 33111, two first T-shaped frames 33112 arranged oppositely and spaced apart and slidingly matched with two lateral slide grooves 311 on the first bottom plate 33111, and a first π-shaped frame 33113 arranged above the first T-shaped frame 33112 in a substantially π-shaped shape, wherein the bottom of the first π-shaped frame 33113 is respectively penetrated through the lateral slide grooves 311 and fixed to the first T-shaped frame 33112 as a whole. There are two lateral shaping blocks 3312 arranged oppositely and spaced apart above the first π-shaped frame 33113, and any lateral shaping block 3312 is L-shaped. The second slider 3313 is fixed on the transverse shaping frame 3311, more specifically on the first bottom plate 33111, and is slidably matched with the second linear guide rail 50 fixed on the bottom of the base plate 31. The extension direction of the second linear guide rail 50 is consistent with the displacement direction of the shaping mechanism 30. Figure 1 The left and right directions shown, that is, the extending direction of the second linear guide rail 50 is consistent with the extending direction of the transverse slide groove 311. The two longitudinal displacement shaping members 332 have the same structure, so only one of them is used as an example for description. Figure 6As shown, any longitudinal displacement shaping member 332 includes a longitudinal shaping frame 3321, a longitudinal shaping block 3322, a third slider 3323, a fixed frame 3324 and a pulley assembly 3325. The structure of the longitudinal shaping frame 3321 is similar to that of the transverse shaping frame 3311, that is, it includes a horizontal plate-shaped second bottom plate 33211, two second T-shaped frames 33212 oppositely and spaced apart on the second bottom plate 33211, and a second π-shaped frame 33213 arranged on the two second T-shaped frames 33212 in the shape of a π. The fixed frame 3324 is L-shaped and arranged at the bottom of the second bottom plate 33211. The pulley assembly 3325 is arranged on the fixed frame 3324 and includes a vertical shaft fixed on the fixed frame 3324 and a pulley arranged at the upper end of the vertical shaft and rotatable around the axis of the vertical shaft. The pulley is slidably connected to the driving end of the second displacement driving assembly 333. The third slider 3323 is fixed on the longitudinal shaping frame 3321, more specifically on the second bottom plate 33211, and the third slider 3323 is slidably matched with the third linear guide rail 60 fixed on the bottom of the base plate 31. The extension direction of the third linear guide rail 60 is perpendicular to the displacement direction of the shaping mechanism 30. Figure 1 The up-down direction shown is consistent with the extending direction of the longitudinal slide slot 312 .

[0039] For the second displacement driving component 333, Figures 4 to 5 As shown, it includes a driving plate 3332 and a second transverse driving member 3331. The driving plate 3332 is a roughly U-shaped plate member, and one end of the driving plate 3332 is fixedly connected to the transverse shaping frame 3311, more specifically to one end of the first bottom plate 33111. The driving end of the transverse driving member is fixedly connected to the other end of the transverse shaping frame 3311, more specifically to the first bottom plate 33111, and the transverse driving member is a cylinder whose driving rod can be extended and retracted along the displacement direction of the shaping mechanism 30. In order to realize that the second transverse driving member 3331 can simultaneously drive the transverse displacement shaping member 331 and the two longitudinal displacement shaping members 332 to move so as to achieve the extrusion, shaping or loosening of the three sides of the soft-pack battery 70 to be tested close to or away from the support table 32, in the embodiment of the utility model, the structure of the driving plate 3332 is as follows Figure 7As shown, the driving plate 3332 includes a connecting plate 33321 whose extension direction is consistent with the extension direction of the longitudinal slide groove 312 and is fixedly connected to the first bottom plate 33111 of the transverse shaping frame 3311, and two inclined plates 33322 respectively extending outward from the ends of the connecting plate 33321. Each inclined plate 33322 is provided with a U-shaped groove 33323 extending from its end toward the connecting plate 33321 along its extension direction. Each groove 33323 is slidably matched with the pulley of the pulley assembly 3325 of the longitudinal displacement shaping member 332 on its corresponding side. Due to the inclination angle of the groove 33323, when the second transverse driving member 3331 drives the transverse displacement shaping member 331 to move relative to the base plate 31 along the transverse slide groove 311 towards the direction close to the support platform 32, that is, close to the frame 10, the pulley will slide from the notch of the groove 33323 to the bottom of the groove in its corresponding groove 33323, thereby making the longitudinal displacement shaping member 332 connected to the pulley assembly 3325 slide relative to the base plate 31 in its respective longitudinal slide groove 312 to approach the side of the soft-pack battery 70 on the support platform 32 on its corresponding side, and vice versa.

[0040] The polymer soft-pack battery 70 test bipolar ear mechanism of the embodiment of the utility model, when in use, the soft-pack battery 70 to be tested is placed on the support table 32 through a mechanical clamp (not shown). The second displacement drive component 333 drives the lateral displacement shaping member 331 and the two longitudinal displacement shaping members 332 to move close to the support table 32 to squeeze and tighten the soft-pack battery 70 on the support table 32, shaping the side of the soft-pack battery 70, and positioning it at the same time. Afterwards, the first displacement drive component 35 drives the entire shaping mechanism 30 to approach the frame 10, and the contact test component 20 on the frame 10 is pressed down to contact the positive and negative pole ears on the soft-pack battery 70 to be tested, and the thickness of the positive and negative pole ears is tested respectively, so as to determine whether there is a problem of pole ear overlap, and NG can be selected in time to reduce the safety hazards of the battery. After the inspection is completed, the first displacement drive assembly 35 is reset, and then the second displacement drive assembly 333 is reset. The mechanical gripper takes out the soft-pack battery 70, and the qualified products are transferred to the next station, and the unqualified products are placed in the NG material box. This ensures that unqualified products are effectively intercepted in this process, reduces product quality problems, and ensures product quality control during the production process.

[0041] The embodiment of the utility model also provides a polymer soft-pack battery 70 packaging production line, including the polymer soft-pack battery 70 testing bipolar ear mechanism of the above-mentioned embodiment. No description or limitation is made on other mechanisms of the packaging production line, which are existing conventional mechanisms. Exemplarily, the testing bipolar ear mechanism of the embodiment of the utility model can be arranged at the end of the assembly line of the packaging production line. Of course, the polymer soft-pack battery 70 packaging production line of the embodiment of the utility model includes an NG material box, which can be arranged next to the polymer soft-pack battery 70 testing bipolar ear mechanism, without specific limitation. When the detection shows that there is no bipolar ear, that is, it is qualified, it flows into the next station to perform the next process; and when the detection shows that there is a bipolar ear, that is, a defective product, the unqualified soft-pack battery 70 is placed in the NG material box.
