Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-channel chemical composition container equipment, in particular to a flexible needle plate integrated charging and discharging equipment. BACKGROUND

[0002] In the battery production process, the battery needs to be continuously charged and discharged to adjust the battery performance, which is also called battery formation process. The common integrated charging and discharging equipment, such as the integrated temperature control charging and discharging equipment with publication number 218273187U, integrates the motion mechanism part of the battery tray and the change type with the power supply part in contact with the battery into one rack. When the power supply part needs to be maintained, the power supply part is extracted out of the rack using a drawer structure, exposed outside the rack, and convenient for maintenance. The above technology has the following shortcomings: 1. Since the power supply part adopts a drawer structure, enough space must be reserved outside the rack to expose the entire power supply part outside the rack, which will significantly increase the use space of the integrated charging and discharging equipment; 2. The power supply board card is vertically upwardly inserted and maintained. When the rack height is high or the topmost rack needs to be maintained, it is difficult for the maintenance personnel to pull out the power supply board card upwardly, and the maintenance is not convenient; 3. Because of the drawer structure of the power supply part, when the power supply part is completely exposed outside the rack, the entire power supply part presents a cantilever beam structure, that is, the center of gravity of the power supply part is outside the rack and far away from the edge of the rack. This state has strict requirements for the structure of the power supply part. If it is in this state for a long time, the structure of the power supply part may be damaged. SUMMARY

[0003] In view of the above problems, the present application provides a flexible needle plate integrated charging and discharging equipment.

[0004] The flexible needle plate integrated charging and discharging equipment uses a template including a cuboid rack, the rack is horizontally placed, and the internal space of the rack is provided with a motion middle frame connected to the top of the rack through a gas cylinder, which can be pushed up and down by the gas cylinder; the motion middle frame is provided with a battery tray for carrying batteries, and the direction of extension of one edge of the bottom of the rack is defined as the front-back direction, and the direction of extension of the other edge is defined as the left-right direction;

[0005] The front and rear ends of the frame above the battery tray of the flexible needle plate integrated charging and discharging equipment are respectively provided with linear slide rails in the left-right direction, and a plurality of flexible needle plates extending in the front-rear direction and provided with rollers at the front and rear ends are slidably arranged on the linear slide rails; the rollers are respectively connected with a vertical driving plate structure, two front-rear flush driving plate structures are connected with the same vertical central structure through a front-rear extending driving plate module, thereby forming an outer frame of the flexible needle plate; the left and right ends of the top of the driving plate structure and the central structure are respectively provided with a positioning hole, and the driving plate structures and the central structures adjacent to each other in the left-right direction are connected through a fixing buckle connected with the positioning holes; the top of the driving plate module is provided with a wire connector, and the wire connectors of the driving plate modules adjacent to each other in the front-rear direction are connected with wires capable of transmitting electrical signals; the bottom of the rightmost driving plate structure is provided with a third chain extending to the left, and the bottoms of the remaining driving plate structures are provided with first chains extending to the right, and the first chains and the third chains adjacent to each other in the left-right direction are rotatably connected through second chains; the bottom of the driving plate module is provided with a probe structure for contacting a plurality of battery pole columns in the front-rear direction.

[0006] More specifically, the wire uses a flexible material, and the fixing buckle uses a rigid material.

[0007] When the flexible needle plate integrated charging and discharging equipment is normally working, the upper surface of the battery carried by the battery tray is in contact with the lower surface of the probe assembly carried by the flexible needle plate, at this time, each driving plate module uses the wire to interact and communicate signals, and controls the battery formation process. The front and rear driving assemblies are connected with each other through the fixing buckle, so as to ensure that the structure of the entire flexible needle plate assembly is stable and reliable.

[0008] When the flexible needle plate integrated charging and discharging equipment needs to be maintained, an external worker pulls the flexible needle plate out of the linear slide rail from the right side until the driving plate module in the flexible needle plate is completely exposed outside the frame and is in front of the maintenance personnel, so as to facilitate maintenance. When the first section of the driving plate assembly is exposed outside the frame, the wire connected between the front and rear flexible needle plates is pulled out first, and then the fixing buckle is pulled out. At this time, the leftmost flexible needle plate is lowered downward due to gravity, and can be rotated by a certain angle along the chain structure because the driving plate structure is fixed by the first and second chains below the driving plate structure. The ideal state is 90°, so that the driving plate module is directly faced to the maintenance side.

[0009] When the maintenance of the driving plate module is completed, the driving plate module is sequentially placed back to the original position from the maintenance side, the fixing buckle between the front and rear driving assemblies is installed back first, the wire of the driving plate module is installed back, and finally the rollers on the two sides of the flexible needle plate are pushed back along the linear slide rail until all the flexible needle plates return to the inside of the mechanism, and the probe assemblies correspond to the batteries one by one.

[0010] Compared with the existing common integrated charge-discharge equipment, when the flexible needle plate of the flexible needle plate integrated charge-discharge equipment is pulled out for maintenance, the flexible needle plate occupies the external space L2 of the rack, which is much smaller than the space L1 occupied by the needle plate assembly of the conventional integrated charge-discharge equipment for maintenance, and the design of the probe and the driving plate module fusion makes the flexible needle plate occupy the height H2 inside the rack, which is also much smaller than the height H1 of the conventional integrated charge-discharge equipment.

[0011] The beneficial effects of the present application are that the flexible needle plate carrying the probe will droop at a certain angle when pulled out for maintenance, and the straight face is convenient for maintenance while saving external space, and the center of gravity of the flexible needle plate is close to the rack, which is more stable. The driving assembly of the flexible needle plate is close to the probe, which reduces the cable length and saves the cost. BRIEF DESCRIPTION OF DRAWINGS

In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the present specification and the features of the different embodiments or examples without contradiction.

[0027] The following will first illustrate an exemplary embodiment of the internal battery formation device used in the present application.

[0028] A flexible needle plate integrated charging and discharging device uses a template including a cuboid frame 1, which is horizontally placed, and the internal space of the frame is provided with a moving middle frame 2 connected to the top of the frame by a pneumatic cylinder, which can be pushed up and down by the pneumatic cylinder; the moving middle frame 2 is provided with a battery tray 3 for carrying batteries, and the direction of extension of one edge of the bottom of the frame 1 is defined as the front-back direction, and the direction of extension of the other edge is defined as the left-right direction.

[0029] The front and rear ends of the frame above the battery tray of the flexible needle plate integrated charging and discharging device of the present application are respectively provided with left-right linear slides 11, and a plurality of flexible needle plates 5 extending in the front-back direction and provided with rollers 51 at the front and rear ends can slide left and right on the linear slides 11; the rollers 51 are respectively connected to a vertical drive plate structure 521, two front-back flush drive plate structures 521 are respectively connected to the same vertical central structure 526 through a front-back extending drive plate module 522, forming an outer frame of the flexible needle plate 5; the left and right ends of the top of the drive plate structure 521 and the central structure 526 are respectively provided with a positioning hole, and the drive plate structures 521 and the central structures 526 adjacent to each other are connected through a fixed buckle 525 connected to the positioning holes; the top of the drive plate module 522 is provided with a wire connector 523, and the wire connectors 523 of the drive plate modules 522 adjacent to each other in the front-back direction are connected with wire 524 capable of transmitting electrical signals; the bottom of the rightmost drive plate structure 521 is provided with a third chain 533 extending to the left, and the bottoms of the remaining drive plate structures are provided with first chains 531 extending to the right, and the first chains 531 and the third chains 533 adjacent to each other are rotatably connected through second chains 532; the bottom of the drive plate module 522 is provided with a plurality of probe structures 54 for contacting battery poles in the front-back direction.

[0030] In some embodiments, the wire 524 uses a flexible material, and the fixed buckle 525 uses a rigid material.

[0031] When the flexible needle plate integrated charge and discharge equipment is working normally, the upper surface of the battery carried by the battery tray is in contact with the lower surface of the probe assembly 54 carried by the flexible needle plate, at this time, each drive plate module uses the wire 524 to interact and communicate signals, and controls the battery formation process. The front and rear drive assemblies are connected to each other by using the fixed buckle, so as to ensure that the structure of the entire flexible needle plate assembly is stable and reliable.

[0032] When the flexible needle plate integrated charge and discharge equipment needs to be maintained, an external worker pulls the flexible needle plate 5 out of the linear slide rail 11 from the right side until the inner drive plate module of the flexible needle plate is completely exposed outside the rack and is in front of the maintenance personnel, so as to facilitate maintenance. The rollers slide out along the linear slide rails on both sides, when the first section of the drive plate assembly is exposed outside the rack, the wire connected between the front and rear flexible needle plates is pulled out first, and then the fixed buckle is pulled out. At this time, the leftmost flexible needle plate falls downward due to gravity, and since the structure of the drive plate is fixed below by the first and second chains, it can rotate by a certain angle along the chain structure, and the ideal state is 90°, so that the drive plate module is directly faced to the maintenance side.

[0033] When the maintenance of the drive plate module 522 is completed, the drive plate module 522 is sequentially put back to the original position from the maintenance side (the right side), the fixed buckle 525 between the front and rear drive assemblies is put back first, then the wire 524 of the drive plate module is put back, and finally the rollers 51 on both sides of the flexible needle plate 5 are pushed back along the linear slide rails until all the flexible needle plates return to the inside of the mechanism, and the probe assembly is one-to-one corresponding to the battery.

[0034] Compared with the existing common integrated charge and discharge equipment, when the flexible needle plate of the flexible needle plate integrated charge and discharge equipment is pulled out for maintenance, the space L2 occupied by the flexible needle plate outside the rack is much smaller than the space L1 occupied by the needle plate assembly of the conventional integrated charge and discharge equipment during maintenance. The design of the fusion of the probe and the drive plate module makes the height H2 occupied by the flexible needle plate inside the rack much smaller than the height H1 of the conventional integrated charge and discharge equipment.

[0035] The beneficial effects of the present application are that the flexible needle plate carrying the probe falls by a certain angle when it is pulled out for maintenance, is directly faced to the maintenance personnel, saves external space, and is convenient for maintenance, and the gravity center of the flexible needle plate is close to the rack, which is relatively stable. The drive assembly of the flexible needle plate is close to the probe, which reduces the length of the cable and saves the cost.

[0036] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be understood as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
