Description

Technical Field

[0001] The utility model relates to the field of press equipment for the production of soft-pack batteries, and particularly relates to a soft-pack battery press mechanism. Background Art

[0002] With the wide application and development of portable electronic products, the demand for soft-pack batteries in electronic products has increased rapidly, thus promoting the development and upgrading of the production capacity of soft-pack batteries. In the prior art, the formation and grading process of soft-pack batteries is often completed by manually placing them one by one through a charge and discharge device with monomer clamps. However, such charge and discharge devices can no longer meet the production capacity requirements and also bring huge pressure to production costs. With the development of battery production technology at the present stage, it is an inevitable trend to adopt a tray press type for batch production of soft-pack batteries.

[0003] For example, in the battery formation and grading cabinet with the application number CN202210901016.4, the application includes a cabinet body and a stacking mechanism arranged in the cabinet body. The stacking mechanism includes a support frame, a lifting driving member, a clamping device and a supporting device. The support frame is arranged in the cabinet body, the lifting driving member is arranged on the support frame, the clamping device is arranged on the support frame, the supporting device is slidably arranged on the support frame, and the supporting device is located above the clamping device and is connected with the lifting driving member. The supporting device is used for supporting the battery tray. When the lifting driving member drives the supporting device to descend, the supporting device drives the battery tray to approach the clamping device, and the clamping device is used for clamping the battery tab in the battery tray. This device drives the supporting device to perform lifting movement by the lifting driving member, and can perform centralized loading and unloading operations on multiple batteries in units of battery trays, improving the production efficiency of batteries.

[0004] However, the researcher found that in the prior art, the soft-pack battery press mechanism mainly makes the soft-pack battery tab contact the conductive probe through the relative movement between the soft-pack battery tray and the probe mechanism. This relative movement easily causes the soft-pack battery tray to tilt, thus affecting the normal production of soft-pack batteries. Content of the Utility Model

[0005] In order to overcome the technical defect that the soft-pack battery tray is prone to tilt and affect the normal production of soft-pack batteries, the utility model provides a soft-pack battery press mechanism, which is realized according to the following technical solutions:

[0015] Preferably, the tray supporting plate is used to support and press the tray, and the tray can load a plurality of soft-pack batteries.

[0016] Preferably, the guide post mechanism includes a plurality of vertically arranged guide posts and a plurality of linear bearings.

The guide post passes through the lifting top plate, and a linear bearing is arranged at the connection between the guide post and the lifting top plate.

[0017] Preferably, the probe group mechanism is fixedly connected to the plurality of guide posts.

[0018] Preferably, the probe group mechanism includes a probe mounting plate and multiple probe mechanisms. The probe mounting plate is fixedly connected to the plurality of guide posts. The probe mechanisms are mounted on the probe mounting plate. Each probe mechanism includes a conductive probe assembly and a probe support.

One spring is provided on each conductive probe. The conductive probes can move in the probe support and compress the springs. The axes of the springs are parallel to the movement trajectories of the conductive probes.

[0019] Preferably, the power mechanism is a cylinder mechanism. The cylinder mechanism includes at least two cylinders, a plurality of lifting guide shafts, and a plurality of linear bearings. Each cylinder includes a cylinder base and a cylinder joint. The cylinder base is fixedly provided on the lifting bottom plate. A cylinder joint fixing plate is provided below the second fixing plate. The cylinder joint fixing plate is connected to the cylinder joint. One end of the lifting guide shaft is connected to the second fixing plate, and the other end passes through the lifting bottom plate and is sleeved with the linear bearing.

[0020] Preferably, a magnetic induction switch is provided on the cylinder. The magnetic induction switch is used to detect the distance that the cylinder pushes the support mechanism to lift.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] For the soft-pack battery pressing machine mechanism of the present utility model, the entire soft-pack battery pressing machine mechanism is fixed by the first fixing plate, so that other structures are based on the first fixing plate for installation and operation. By arranging the probe group mechanism on the guide post mechanism, the probe group mechanism is fixed, and further the probe mechanisms on the probe group mechanism are fixed, so that the probes are basically aligned and the probes are on a plane parallel to the first fixing plate. By arranging the support mechanism on the connecting plate mechanism, the connecting plate mechanism can drive the support mechanism to lift in the vertical direction, and the support fixing plate of the support mechanism is parallel to the first fixing plate.

[0024] By laminating the probe group mechanism and the support mechanism between the lifting top plate and the second fixed plate, with one probe group mechanism corresponding to be arranged above one support mechanism, that is, there is one support mechanism between two probe group mechanisms in the vertical direction and at least one support mechanism is arranged below one probe group mechanism, relative movement can occur between the support mechanism and the probe group mechanism, and it is fixed that the support mechanism moves towards the probe group mechanism. When this movement is carried out, the support mechanism can always maintain the original stable placement state, avoiding the influence of external forces on the tray installed on the support mechanism, and further pressing the tabs of the soft-pack battery installed on the support mechanism into contact with the conductive probes installed on the probe group mechanism;

[0025] Through the foregoing structure and by laminating the probe mechanism and the support mechanism between the lifting top plate and the second fixed plate, the plane where multiple conductive probes are aligned is parallel to the plane where the tray support plate of the support mechanism is located. In the actual production of soft-pack batteries, only the support mechanism is pushed up and down, and the tabs of multiple soft-pack batteries loaded on the tray are in contact with multiple conductive probes synchronously, without causing the tray carrier to tilt and the soft-pack batteries to shift due to this contact, ultimately avoiding the influence on the normal production of soft-pack batteries.

[0026] On the other hand, in this application, the support mechanism and the probe group mechanism are indirectly connected through the connecting plate mechanism, the guide post mechanism and the fixed plate assembly, so that there is no direct interaction between the conductive probes and the tray, which is convenient for the installation and maintenance of a single structure.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] The working process of the soft-pack battery pressing machine device according to the embodiment of the present utility model is as follows:

[0058] When the device is running, an external device sends a tray 5 (battery carrier) to the tray positioning mechanism for positioning. After confirming that the tray 5 (battery carrier) is accurately positioned, the power assembly (cylinder 71) drives the tray battery assembly to contact the conductive probe 321 to perform the formation and grading process of the battery. Then, the power assembly (cylinder 71) drives the tray battery assembly to separate from the conductive probe 321, and the external device takes out the tray 5 (battery carrier) to the next process.

[0059] As Figures 1 to 14 shown, a soft-pack battery pressing machine device in this embodiment includes a housing 1 and a plurality of stacked presses arranged inside the housing. The stacked press is the soft-pack battery pressing mechanism of the present utility model patent:

[0060] The stacking press includes a press frame assembly 2, a plurality of probe group mechanisms 3, a plurality of support mechanisms 4, and a power mechanism 7. The press frame assembly 2 includes a fixed plate assembly 21, a connecting plate mechanism 22, and a guide post mechanism 23. The fixed plate assembly 21 is fixedly connected to the guide post mechanism 23, and the connecting plate mechanism 22 is slidably connected to the guide post mechanism 23;

[0061] The support mechanism 4 is connected to the connecting plate mechanism 22 so that the support mechanism 4 can be lifted and lowered in the vertical direction. The probe group mechanism 3 is fixedly connected to the guide post mechanism 23. All the probe group mechanisms 3 and the support mechanisms 4 are stacked. One probe group mechanism 3 is correspondingly provided above one support mechanism 4;

[0062] The support mechanism 4 is used to support and press the tray 5 on which the soft-pack battery 6 is placed. The probe group mechanism 3 is used to install the probe mechanism 32. The soft-pack battery 6 on the tray 5 can be pressed close to and contacted with the probe mechanism 32 along the guide post mechanism 23. The probe mechanism 32 is provided with a spring 323 and a conductive probe 321. The spring 323 is arranged on the conductive probe 321. The conductive probe 321 can be pressed tightly against and contacted with the tab 61 of the soft-pack battery 6 placed on the tray 5, and the conductive probe 321 can be pressed upward and moved;

[0063] The power mechanism 7 is fixedly connected to the fixed plate assembly 21 and the connecting plate mechanism 22 and is used to drive the support mechanism 4 to lift and lower.

[0064] In this embodiment, when the soft-pack battery press equipment is operating, the connecting plate mechanism 22 is driven by the power mechanism 7 to push upward. The support mechanism 4 connected to the connecting plate mechanism 22 will be driven to move upward accordingly, and then the tray 5 supported and pressed on the support mechanism 4 will be driven to move upward synchronously. The tray 5 is provided with a soft-pack battery 6. The probe group mechanism 3 is connected to the guide post mechanism 23. The plane where the probe group mechanism 3 is located is exactly parallel to the plane where the tray 5 is located. The tab 61 of the soft-pack battery 6 is aligned with the position of the conductive probe 321 of the probe mechanism 32 and can be pressed close to and contacted. When the two are in contact, the production of the soft-pack battery 6 is carried out. Through the spring 323 and the conductive probe 321 provided in the probe mechanism 32, the conductive probe 321 can be pressed upward and moved, so that when the tab 61 of the soft-pack battery on the tray 5 contacts the conductive probe 321, there is a certain buffer to avoid damage to the tab 61 due to friction, and at the same time ensure that the tab 61 and the conductive probe 321 are pressed tightly in contact without affecting the normal progress of the production of the soft-pack battery, and finally the yield rate of the production of the soft-pack battery is stably not affected.

[0065] In some preferred embodiments, the fixed plate assembly 21 includes a first fixed plate 211 and a second fixed plate 212. One side of the first fixed plate 211 is connected to the housing 1; the guide post mechanism 23 includes a plurality of vertically arranged guide posts 231. One end of the guide post 231 is fixedly connected to the first fixed plate 211, and the other end is fixedly connected to the second fixed plate 212; the connecting plate mechanism 22 includes a lifting top plate 213, a lifting bottom plate 214, and two vertically arranged transmission connectors 221. One end of the transmission connector 221 is connected to the lifting top plate 213, and the other end is connected to the lifting bottom plate 214. The guide post 231 passes through the lifting top plate 213, and a linear bearing 232 is provided at the connection position between the guide post 231 and the lifting top plate 213; the transmission connector 221 is connected to the support mechanism 4.

[0066] In this embodiment, the guide post mechanism 23 is connected to the first fixed plate 211 and the second fixed plate 212, serving as a bracket for fixing the probe group mechanism 3 and guiding the connecting plate mechanism 22. The first fixed plate 211 is connected to the housing 1, which is the installation reference and working reference for other structures of the laminating press in this embodiment. The connecting plate mechanism 22 is connected to the lifting top plate 213 and the lifting bottom plate 214. The connecting plate mechanism 22 includes transmission connectors 221, a lifting top plate 213, and a lifting bottom plate 214. The transmission connector 221 is connected to the support mechanism 4. Through the foregoing mechanisms, the probe group mechanism 3 and the support mechanism 4 can be approximated and separated. When the soft-pack battery pressing machine equipment in this embodiment is working properly, they can move towards each other to approach and move away from each other to separate. It can be understood that, as Figures 4 to 6 shown, both ends of the guide post 231 are perpendicularly and fixedly connected to the first fixed plate 211 and the second fixed plate 212 respectively, and both ends of the transmission connector 221 are perpendicularly and fixedly connected to the lifting top plate 213 and the lifting bottom plate 214 respectively. The guide post 231 passes through the lifting top plate 213 and is slidably connected thereto, so that both the probe group mechanism 3 and the support mechanism 4 are in a position parallel to the plane where the first fixed plate 211 is located. When the two approach each other, a plurality of conductive probes 321 provided on the probe group mechanism 3 can simultaneously press and contact the ears 61 of a plurality of soft-pack batteries 6 placed on the tray 5, avoiding the reduction of the production yield of soft-pack batteries caused by uneven contact parts of the conductive probes 321.

[0067] In some preferred embodiments, multiple probe group mechanisms 3 and multiple supporting mechanisms 4 are stacked between the lifting top plate 213 and the second fixed plate 212, the probe group mechanism 3 includes a probe mounting plate 31, the probe mounting plate 31 is fixedly connected to multiple guide pillars 231, and multiple groups of probe mechanisms 32 are installed on the probe mounting plate 31. The probe mechanism 32 includes a conductive probe 321 assembly and a probe bracket 324. The conductive probe 321 assembly includes multiple conductive probes 321, multiple positioning pillars 322 and multiple springs 323. The conductive probe 321 is inserted into the probe bracket 324, and each positioning pillar 322 is fixedly connected to the probe bracket 324, which can limit the movement of each conductive probe 321 in the probe bracket 324. Each conductive probe 321 is provided with a spring 323, and the axis of the spring 323 is parallel to the moving trajectory of the conductive probe 321.

[0068] In this embodiment, a plurality of probe group mechanisms 3 and a plurality of support mechanisms 4 are stacked between the lifting top plate 213 and the second fixed plate 212. It can be known that the support mechanism 4 can be pushed up and down by the power mechanism 7 through the connecting plate mechanism 22. Specifically, the support mechanism 4 is indirectly driven up and down by the lifting top plate 213 and the lifting bottom plate 214 connected to the transmission connecting member 221. The lifting top plate 213 can move along the guide column 231. The lifting distance of the support mechanism 4 is the moving distance between the first fixed plate 211 and the lifting top plate 213.

[0069] The probe mounting plate 31 is a component parallel to the probe group mechanism 3 and the first fixing plate 211 as a reference. The probe mounting plate 31 is equipped with multiple probe mechanisms 32. The utility model can improve the production efficiency of soft-pack batteries of various specifications, such as Figures 4 to 14 As shown, the conductive probe assembly includes a plurality of conductive probes 321. Considering that the current and voltage need to be measured at the battery tab 61 during the production of the soft-pack battery, a plurality of conductive probes 321 are provided to measure the voltage and current information of the positive and negative electrodes of the battery tab 61. Considering that the working principle and structure of the conductive probe 321 for measuring voltage and current in the prior art are inconsistent, in order to make the collection of voltage and current information more comprehensive and precise, at least four positive current probes, positive voltage probes, negative current probes and negative voltage probes need to be provided respectively;

[0070] In this embodiment, it can be understood that the setting of the positioning column 322 is only one way to realize the structure of ensuring that the conductive probe 321 is inserted into the probe bracket 324 in the utility model. In addition, this purpose can also be achieved by a structure such as a buckle, a protrusion or a combination of the two.

[0071] On the other hand, a spring 323 is provided on the conductive probe, such as Figures 12 to 14As shown, in one embodiment of the present invention, a guide groove is provided on the conductive probe 321. Clasps are provided at both ends of the guide groove. Both ends of the spring 323 are connected to the two clasps, and the positioning post 322 passes through the guide groove. When the soft-pack battery pressing machine device of the present invention is working, the conductive probe 321 in the probe mechanism 32 can be pressed and moved when the supporting mechanism 4 moves upward. Since the axis of the spring 323 is parallel to the moving track of the conductive probe 321, when the conductive probe 321 is tightly pressed and contacted by the tab 61 of the soft-pack battery 6, it moves upward to buffer the force, avoiding damage to the tab 61 of the soft-pack battery 6 and thus affecting the yield rate of the production of the soft-pack battery 6.

[0072] In some preferred embodiments, the supporting mechanism 4 includes a tray supporting plate 41. The tray supporting plate 41 is used to support and press the tray 5. The tray 5 is used to place a plurality of soft-pack batteries 6. A plurality of insulating parts 52 are regularly arranged on the tray 5. An isolating part 53 is provided on the insulating part 52. A space for placing the soft-pack battery 6 is provided by the plurality of insulating parts 52. The insulating part 52 is used to support the tab 61 of the soft-pack battery 6.

[0073] In this embodiment, as Figures 7 to 11 shown, pressing baffles are symmetrically provided on both sides of the tray supporting plate 41. One end of the pressing baffle close to the door of the housing of this embodiment is set as a through port. A spring pressing piece is provided at the end of the pressing baffle away from the housing door. Through the two pressing baffles and the spring pressing piece, the tray supporting plate 41 supports and presses the tray 5;

[0074] For the consideration of protecting the tray 5, a micro switch 42 and a rear baffle are provided at a position of the tray supporting plate 41 away from the housing door. The micro switch 42 is used to sense and detect whether the tray 5 is placed in place. The rear baffle is used to block the tray 5 to prevent it from continuing to slide backward and hitting the housing 1 after passing through the pressing baffle. Further, chamfer anti-fooling designs are provided at both ends of the rear baffle. Four corners on both sides of the tray 5, two corners on one side are set as rounded corners and two corners on the other side are set as chamfers. When the tray 5 is dragged through the pressing baffle and enters the supporting mechanism 4, the left and right pressing baffles prevent the tray 5 from shifting left and right, making the pressing contact between the conductive probe 321 and the battery tab 61 more accurate. After the tray 5 is in place, the chamfers provided on the tray 5 and the chamfers of the rear baffle need to be aligned to be successfully installed, which can prevent the tray 5 from being placed in the wrong direction. It can be understood that the rounded corner design of the tray 5 is also for this purpose;

[0075] In this embodiment, as Figure 9 shown, the tray 5 is square. A plurality of battery positions 51 for placing the soft-pack batteries 6 are provided on the tray 5 in order to produce a plurality of soft-pack batteries 6 simultaneously. An insulating part 52 is provided in the battery position 51. As Figures 7 to 11As shown, the insulating parts 52 are regularly arranged on the tray 5. In this embodiment, multiple insulating parts 52 are divided into multiple rows, and each row of insulating parts 52 is arranged side by side and aligned with one side of the tray 5. Specifically, it is set as four rows of insulating parts 52. And in this embodiment, a reinforcing bar 54 is also provided on the tray 5. The reinforcing bar 54 is used to structurally connect the whole tray. In this embodiment, the sunken space in the tray 5 is divided into two parts, and multiple insulating parts 52 are respectively arranged in the two parts. A space for placing the soft-pack battery 6 is left between the insulating parts 52. It can be understood that the number of arrangements of the reinforcing bar 54 and the insulating parts 52 is not limited to a fixed natural number. Setting one reinforcing bar 54 and four rows of insulating parts 52 in this embodiment is only one of the more preferred implementation manners;

[0076] In this embodiment, the insulating part 52 is an insulating boss. Considering that the tabs 61 of common soft-pack batteries extend from the side of the soft-pack battery 6, the insulating boss is used to place the tabs 61 of the soft-pack battery. The height of the insulating boss is set to a structure that can make the tabs 61 provided on the soft-pack battery 6 fit with it. A soft insulating material layer is provided on the insulating boss. The soft insulating material layer can be attached by pasting a layer of soft insulating material, or by vulcanizing the insulating part to attach a layer of soft vulcanized rubber. The soft insulating material has high elasticity, which can better ensure full contact between the conductive probe 321 and the tab 61. Further, considering that the tabs 61 of the soft-pack battery may be bent or folded when contacting the conductive probe 321, which may cause a short-circuit fault, a separating part 53 is also provided on the insulating boss. The separating part 53 is used to separate the positive and negative electrodes of the soft-pack battery 6, and can prevent the tabs 61 from being too soft and bending, which may cause a short circuit and thus cause the battery to catch fire;

[0077] On the other hand, the area of the insulating boss is larger than the area of the tab 61 of the soft-pack battery. The tab 61 of the soft-pack battery is placed on the insulating boss, which can be compatible with various specifications of soft-pack batteries 6. Specifically, it is compatible with the tabs 61 of different specifications of soft-pack batteries. The sizes of the tabs 61 of different specifications of soft-pack batteries are generally different. The insulating boss can completely fit and support the tab 61. The insulating boss has a certain length and width to be compatible with tabs 61 of different sizes;

[0078] On the other hand, grooves are provided on the front and back sides of the tray 5, as Figures 7 to 11 shown. The grooves are used to facilitate the pushing and pulling during the installation and disassembly of the tray 5.

[0079] In some preferred embodiments, the power mechanism 7 is a cylinder mechanism, which includes at least two cylinders 71, a plurality of lifting guide shafts 72 and a plurality of linear bearings. The cylinders 71 are arranged below the second fixed plate 212. One end of the lifting guide shaft 72 is connected to the second fixed plate 212, and the other end passes through the lifting bottom plate 214 and is sleeved with the linear bearing, and the linear bearing is fixedly arranged on the lifting bottom plate 214; a magnetic induction switch is arranged on the cylinder 71 to detect the distance that the cylinder 71 pushes the lifting bottom plate 214; the power mechanism 7 further includes a limit component, and the limit component is used to limit the compression amount of the conductive probe 321 pressed by the soft package battery tab 61.

[0080] In this embodiment, considering the need for precise and immediate control in the production of the soft package battery 6, a cylinder mechanism is selected as the power mechanism 7, and the cylinder 71 does not require lubrication, reducing the maintenance cost and environmental pollution. In order to prevent the soft package battery 6 located in the tray 5 from being affected by uneven transmission force, in the soft package battery press device of this embodiment, at least two cylinders 71, a plurality of lifting guide shafts 72 and a plurality of linear bearings are provided in the power mechanism 7 of the stacking press for connection and drive. One end of the lifting guide shaft 72 is connected to the second fixed plate 212, and the second fixed plate 212 is the reference for the cylinder mechanism to push. The other end passes through the lifting bottom plate 214 and is sleeved with the linear bearing fixed on the lifting bottom plate 214, so that the supporting mechanism 4 can be lifted indirectly by the transmission connecting piece 221 through the lifting bottom plate 214;

[0081] In this embodiment, considering that the cylinder 71 drives the supporting mechanism 4 upward to make the soft package battery tab 61 in pressing contact with the conductive probe 321 will cause the conductive probe 321 to be pressed upward and move, in order to prevent the probe mechanism 32 installing the conductive probe 321 from being damaged, a magnetic induction switch and a limit component are arranged on the cylinder mechanism. The magnetic induction switch detects the distance that the cylinder 71 pushes the lifting bottom plate 214, so that the operator can adjust the upward driving distance of the cylinder 71 to be less than the limit distance that the conductive probe 321 is pressed and moves. The limit component uses the physical hard limit method of screw nuts, so that when the cylinder 71 drives upward, the limit nut 74 is driven in place to prevent it from being further pressed upward.
