[0056] In order to solve the problem that the soft-pack battery tabs are easily damaged during soft-pack battery press production, which affects the yield rate of soft-pack battery production, the present invention provides a soft-pack battery press device, which can prevent the soft-pack battery tabs from being bent or folded while ensuring that the conductive probes involved in the production are in full tight contact with the tabs of the soft-pack battery, thereby ensuring the yield rate of soft-pack battery production.

[0057] The soft pack battery press equipment of the present invention has the following working process:

[0058] When the equipment is running, the external equipment sends the tray 5 (battery carrier) to the tray positioning mechanism for positioning, confirms that the tray 5 (battery carrier) is accurately positioned, and the power component (cylinder 71) drives the tray battery assembly to contact the conductive probe 321 to carry out the battery chemical composition process. The power component (cylinder 71) drives the tray battery assembly to separate from the conductive probe 321, and the external equipment takes out the tray 5 (battery carrier) to the next process.

[0059] like Figure 1 to Figure 14 As shown, a soft pack battery press device in this embodiment includes a shell 1 and a plurality of stacked presses arranged in the shell:

[0060] The laminating press comprises 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 comprises a fixed plate assembly 21, a connecting plate mechanism 22 and a guide column mechanism 23. The fixed plate assembly 21 is fixedly connected to the guide column mechanism 23, and the connecting plate mechanism 22 and the guide column mechanism 23 are slidably connected.

[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 column mechanism 23. All probe group mechanisms 3 and support mechanisms 4 are stacked, and one probe group mechanism 3 is correspondingly arranged 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 and contacted with the probe mechanism along the guide column mechanism 23. The probe mechanism is provided with a spring 323 and a conductive probe 321. The spring 323 is provided on the conductive probe 321. The conductive probe 321 can be pressed 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 and moved upward.

[0063] The power mechanism 7 is fixedly connected to the fixed plate assembly 21 and the connecting plate mechanism 22 to drive the supporting mechanism 4 to move up and down. In this embodiment, when the soft-pack battery press equipment is running, the connecting plate mechanism 22 is driven upward by the power mechanism 7, and the supporting mechanism 4 connected to the connecting plate mechanism 22 will be moved upward together, so that the tray 5 supported and pressed on the supporting mechanism 4 is synchronously driven to move upward, and a soft-pack battery 6 is arranged on the tray 5, and the probe group mechanism 3 is connected to the guide column mechanism 23, and the plane where the probe group mechanism 3 is located is exactly parallel to the plane where the tray 5 is located, and the pole ear 61 of the soft-pack battery 6 is aligned with the conductive probe 321 of the probe mechanism 32 and can be pressed into contact. When the two are in contact, the production of the soft-pack battery 6 is carried out, and the spring 323 and the conductive probe 321 provided in the probe mechanism 32 can make the conductive probe 321 be pressed upward and moved, so that the pole ear 61 of the soft-pack battery on the tray 5 has a certain buffer when contacting with the conductive probe 321, avoiding the pole ear from being damaged due to friction, and at the same time ensuring that the pole ear 61 and the conductive probe 321 are fully pressed and contacted without affecting the normal production of the soft-pack battery, and finally making the yield rate of the soft-pack battery production stable and unaffected.

[0064] In some preferred embodiments, the fixed plate assembly 21 includes a first fixed plate 211 and a second fixed plate 212, and one side of the first fixed plate 211 is connected to the shell 1; the guide column mechanism 23 includes a plurality of vertically arranged guide columns 231, one end of the guide column 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 connecting members 221, one end of the transmission connecting member 221 is connected to the lifting top plate 213, and the other end is connected to the lifting bottom plate 214, the guide column 231 is penetrated through the lifting top plate 213 and a linear bearing 232 is provided at the connection position between the guide column 231 and the lifting top plate 213; the transmission connecting member 221 is connected to the supporting mechanism 4.

[0065] In this embodiment, the guide column mechanism 23 is connected to the first fixed plate 211 and the second fixed plate 212, which are used 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 shell 1, which is the installation reference and working reference of other structures of the stacking 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 a transmission connecting member 221, a lifting top plate 213 and a lifting bottom plate 214. The transmission connecting member 221 is connected to the supporting mechanism 4. Through the aforementioned mechanism, the probe group mechanism 3 and the supporting mechanism 4 can be approached and separated. When the soft-pack battery press equipment of this embodiment is working normally, they can move towards each other and move away from each other. It can be understood that, Figures 4 to 6As shown, the two ends of the guide column 231 are respectively vertically fixed to the first fixed plate 211 and the second fixed plate 212, and the two ends of the transmission connecting member 221 are respectively vertically fixed to the lifting top plate 213 and the lifting bottom plate 214, and the guide column 231 is penetrated through the lifting top plate 213 and is slidably connected thereto, so that the probe group mechanism 3 and the supporting mechanism 4 are both in a position parallel to the plane where the first fixed plate 211 is located. When the two are close to each other, the multiple conductive probes 321 provided in the probe group mechanism 3 and the pole ears 61 of the multiple soft-pack batteries 6 placed on the tray 5 can be pressed and contacted at the same time, so as to avoid the uneven contact parts of the conductive probes 321, which will lead to a decrease in the production yield of the soft-pack batteries.

[0066] 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.

[0067] In this embodiment, multiple probe group mechanisms 3 and multiple supporting mechanisms 4 are stacked between the lifting top plate 213 and the second fixed plate 212. It can be known that the supporting mechanism 4 can be driven to rise and fall by the power mechanism 7 through the connecting plate mechanism 22. Specifically, when the lifting bottom plate 214 is driven to rise and fall by the power mechanism 7, the supporting mechanism 4 is indirectly driven to rise and fall 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 supporting mechanism 4 is the moving distance between the first fixed plate 211 and the lifting top plate 213; the probe mounting plate 31 is a component that is parallel to the first fixed plate 211 as a reference, and the probe mounting plate 31 is installed with multiple groups of probe mechanisms 32. The present invention can improve the production efficiency of soft-pack batteries of various specifications, such as Figures 4 to 14As 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;

[0068] 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 present invention. In addition, this purpose can also be achieved by a structure such as a buckle, a protrusion, or a combination of the two.

[0069] On the other hand, a spring 323 is provided on the conductive probe, such as Figures 12 to 14 It is shown that an embodiment of the present invention is that a guide groove is provided on the conductive probe 321, and buckles are provided at both ends of the guide groove, both ends of the spring 323 are connected to the two buckles, and the positioning column 322 passes through the guide groove. When the soft-pack battery press device of the present invention is in operation, the conductive probe 321 in the probe mechanism 32 can be pressed and moved when the supporting mechanism 4 moves upward, and the axis of the spring 323 is parallel to the moving trajectory of the conductive probe 321, so that the conductive probe 321 moves upward when it is pressed and contacted by the pole ear 61 of the soft-pack battery 6 to buffer the force, thereby avoiding damage to the pole ear 61 of the soft-pack battery 6 and affecting the yield rate of the soft-pack battery 6 production.

[0070] In some preferred embodiments, the supporting mechanism 4 includes a tray supporting plate 41, which is used to support and compress the tray 5, and the tray 5 is used to place multiple soft-pack batteries 6. The tray 5 is provided with multiple regularly arranged insulating parts 52, and the insulating parts 52 are provided with isolation parts 53. The multiple insulating parts 52 are provided with space for placing the soft-pack batteries 6, and the insulating parts 52 are used to support the pole ears 61 of the soft-pack batteries 6.

[0071] In this embodiment, Figures 7 to 11 As shown, the tray support plate 41 is symmetrically provided with compression baffles on both sides, the compression baffle close to the door of the shell of this embodiment is set as a through opening, and the compression baffle away from the shell door is provided with a spring compression piece, and the tray support plate 41 supports and compresses the tray 5 through the two compression baffles and the spring compression piece;

[0072] In consideration of protecting the tray 5, a micro switch 42 and a rear baffle are provided at a position of the tray support plate 41 away from the shell door. The micro switch 42 is used to sense whether the tray 5 is in place, and the rear baffle is used to block the tray 5 from continuing to slide backward after passing through the clamping baffle and hitting the shell 1 to be damaged. Furthermore, both ends of the rear baffle have chamfered anti-fool design. The four corners on both sides of the tray 5 are set as rounded corners on one side and chamfered corners on the other side. When the tray 5 is dragged through the clamping baffle into the supporting mechanism 4, the left and right clamping baffles prevent the tray 5 from shifting left and right, so that the conductive probe 321 and the battery pole ear 61 are pressed and contacted more accurately. After the tray 5 is in place, the chamfer provided on the tray 5 is aligned with the chamfer of the rear baffle to be successfully installed, which can prevent the tray 5 from being placed upside down when it is placed. It can be understood that the rounded corner design of the tray 5 is also for this purpose.

[0073] In this embodiment, Fig. 9 As shown, the tray 5 is square, and a plurality of battery positions 51 for placing soft-pack batteries 6 are provided on the tray 5 in order to produce a plurality of soft-pack batteries 6 at the same time. An insulating portion 52 is provided at the battery position 51, such as Figures 7 to 11 As shown, the insulating parts 52 are regularly arranged on the tray 5. In this embodiment, the 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, four rows of insulating parts 52 are set, and in this embodiment, a reinforcing bar 54 is also provided on the tray 5, and the reinforcing bar 54 is used to connect the tray as a whole. In this embodiment, the recessed space in the tray 5 is divided into two parts, and the two parts are respectively provided with multiple insulating parts 52. Space for placing soft-pack batteries 6 is reserved between the insulating parts 52. It can be understood that the number of arrangements of the reinforcing bars 54 and the insulating parts 52 is not limited to a fixed natural number. In this embodiment, providing one reinforcing bar 54 and four rows of insulating parts 52 is only one of the more preferred implementations;

[0074] In this embodiment, the insulating portion 52 is an insulating boss. Considering that the pole ear 61 of a common soft-pack battery extends from the side of the soft-pack battery 6, the insulating boss is used to place the pole ear 61 of the soft-pack battery. The height of the insulating boss is set to a structure that enables the pole ear 61 set on the soft-pack battery 6 to 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 portion and attaching a layer of soft vulcanized rubber. The soft insulating material has high elasticity and can better ensure that the conductive probe 321 is in full contact with the pole ear 61. Furthermore, considering that the pole ear 61 of the soft-pack battery may be bent and folded when in contact with the conductive probe 321, thereby causing a short circuit fault, an isolating portion 53 is also provided on the insulating boss. The isolating portion 53 is used to separate the positive and negative electrodes of the soft-pack battery 6, which can prevent the pole ear 61 from being too soft and bent to cause a short circuit, thereby causing the battery to spontaneously combust;

[0075] On the other hand, the area of ​​the insulating boss is larger than the area of ​​the soft-pack battery pole ear 61. The soft-pack battery pole ear 61 is placed on the insulating boss, which can be compatible with soft-pack batteries 6 of various specifications, specifically, the pole ears 61 of soft-pack batteries of different specifications. The sizes of the pole ears 61 of soft-pack batteries of different specifications are generally different. The insulating boss can completely fit and support the pole ear 61. The insulating boss has a certain length and width to be compatible with pole ears 61 of different sizes.

[0076] On the other hand, the tray 5 is provided with grooves on the front and rear sides. Figures 7 to 11 As shown, the groove is used to facilitate the pushing and pulling out of the tray 5 during installation and removal.

[0077] In some preferred embodiments, the power mechanism 7 is a cylinder mechanism, which includes at least two cylinders 71, multiple lifting guide shafts 72 and multiple linear bearings. The cylinder 71 is 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 is passed through the lifting base plate 214 and is sleeved with the linear bearing, which is fixed on the lifting base plate 214; a magnetic induction switch is provided on the cylinder 71 to detect the distance that the cylinder 71 pushes the lifting base plate 214; the power mechanism 7 also includes a limit assembly, which is used to limit the compression amount of the conductive probe 321 pressed by the soft-pack battery ear 61.

[0078] In this embodiment, considering that the production of the soft-pack battery 6 requires precise and instant control, a cylinder mechanism is selected as the power mechanism 7, and the cylinder 71 does not need lubrication, which reduces maintenance costs and environmental pollution. In order to prevent the soft-pack battery 6 located in the tray 5 from being affected by the uneven force of the transmission, the soft-pack battery press device of this embodiment has a power mechanism 7 of the stacking press provided with at least two cylinders 71, a plurality of lifting guide shafts 72 and a plurality of linear bearings for connecting and driving. One end of the lifting guide shaft 72 is connected to the second fixed plate 212, which is the reference for the cylinder mechanism to push, and the other end is penetrated through the lifting bottom plate 214 and is sleeved with the linear bearing fixed on the lifting bottom plate 214, so that the support mechanism 4 can be lifted and lowered by the indirect action of the transmission connector 221 through the lifting bottom plate 214;

[0079] In this embodiment, considering that the cylinder 71 drives the supporting mechanism 4 upward so that the soft-pack battery ear 61 is pressed and contacted with the conductive probe 321, the conductive probe 321 will be pressed and moved upward, in order to avoid the probe mechanism 32 on which the conductive probe 321 is installed from being damaged, a magnetic induction switch and a limit assembly are provided on the cylinder mechanism. The magnetic induction switch detects the distance that the cylinder 71 pushes the lifting base 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 moved. The limit assembly uses the physical hard limiting method of the screw nut so that when the cylinder 71 is driven upward, the limit nut 74 is driven into place to prevent it from being further pressed upward.

[0080] In some preferred embodiments, the housing is provided with a grating assembly, and the grating assembly is used for production early warning.

[0081] In this embodiment, a pair of gratings 8 are provided above and below the shell door, a control panel 10 is provided at the shell door, and multiple fan assemblies 9 are provided on the back of the shell 1. The pair of gratings 8 include a grating 8 at the radiating end and a grating 8 at the receiving end. The grating assembly is used to detect whether the hands are taken out during manual feeding to prevent the machine from hurting people. The fan assembly 9 is used for heat dissipation. The control panel 10 is provided with a power control button, a positive and negative pole status control button, an emergency stop knob and a main power switch.

[0082] The working principle of the soft pack battery press equipment of the present invention is:

[0083] A soft-pack battery press device comprises a shell 1 and a plurality of stacked presses arranged in the shell 1, the stacked presses comprising a press frame assembly 2, a probe group mechanism 3, a support mechanism 4 and a power mechanism 7, the press frame assembly 2 comprises a fixed plate assembly 21, a connecting plate mechanism 22 and a guide column mechanism 23, the fixed plate assembly 21 is fixedly connected to the guide column mechanism 23, the connecting plate mechanism 22 is slidably connected to the guide column mechanism 23, the probe group mechanism 3 is used to install the probe mechanism 32, the support mechanism 4 is used to support and press a tray 5 loaded with soft-pack batteries 6, and the power mechanism 7 is used to drive the support mechanism 4 to rise and fall.

[0084] Specifically, when the stacking press in the present patent is working, the cylinder 71 performs linear telescopic motion, and the cylinder base drives the lifting base plate 214 to lift and lower. The lifting base plate 214 drives the supporting mechanism 4 connected to the transmission connecting member 221 to lift and lower through the transmission connecting member 221. The supporting mechanism 4 supports and presses the carrier tray 5 loaded with the soft-pack battery 6, and the tray 5 drives the soft-pack battery 6 to lift and lower. The pole ear 61 of the soft-pack battery 6 is placed on the insulating part 52, and the pole ear 61 of the soft-pack battery 6 is close to the probe mechanism 32 installed on the probe group mechanism 3 that is always fixedly connected to the guide column 231. The conductive probe 321 on the probe mechanism 32 contacts the pole ear 61 of the soft-pack battery 6 to produce the soft-pack battery.

[0085] By fixing the fixed plate assembly 21 to the guide post mechanism 23 respectively, a stable laminating press frame can be provided; by slidingly connecting the guide post mechanism 23 and the connecting plate mechanism 22, and connecting the support mechanism 4 to the connecting plate mechanism 22, the power mechanism 7 can drive the support mechanism 4 to rise and fall through the connecting plate mechanism 22, and further lift the tray 5 loaded with soft-pack batteries 6 arranged on the support mechanism 4. Since the probe mechanism 3 is installed on the probe group mechanism 3, and the probe mechanism 32 is provided with a spring 323 and a conductive probe 321, the tray 5 is moved upward. When the probe mechanism 32 is lifted, the tab 61 of the soft-pack battery 6 loaded on the tray 5 can be pressed into contact with the conductive probe 321 to complete the chemical composition production process of the soft-pack battery 6; the spring 323 provided on the probe mechanism 32 can provide a certain buffer when the tab 61 of the soft-pack battery 6 on the tray 5 contacts the conductive probe 321 to avoid damage to the tab 61 due to friction, and at the same time, it can ensure that the tab 61 is fully pressed and contacted with the conductive probe 321 without affecting the normal production of the soft-pack battery 6, and finally the yield rate of the soft-pack battery 6 is stable and unaffected.

Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
