[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] Combine the following Figure 1-Figure 6 The utility model is described as a battery module stacking and pressing device.

[0046] like Figure 1-3 As shown, in a battery module stacking and pressing device provided in an embodiment of the utility model, it includes: a support frame structure, a limiter 1 and a side pressing mechanism 2; wherein,

[0047] The support frame structure may be composed of two opposite sub-frames, which may be connected or separated, to provide a relative installation position for the stopper 1;

[0048] The limiting member 1 is a long plate-shaped structure, and a slide groove structure 10 is arranged on one side thereof; the two limiting members 1 are respectively arranged on opposite sides of the support frame structure, so that the slide groove structures 10 of the two limiting members 1 are opposite to each other, and the opposite slide groove structures 10 can form a limiting track for limiting and stacking multiple batteries 3;

[0049] The side pressing mechanism 2 is arranged on the opposite side of the support frame structure. When the battery 3 is assembled between the opposite limiting members 1, the side pressing mechanism 2 is opposite to the side to be pressed of the battery 3, and is used to press and position the multiple batteries 3 between the limiting members 1.

[0050] The pressure detection component is connected to the side pressing mechanism 2 and is used to detect the pressure applied to the battery 3 .

[0051] In the above scheme, the limiter 1 is propped up by the support frame structure, and the limiter 1 is used to form a slide groove structure 10 on the opposite side, and the two ends of the battery 3 can slide into the slide groove structure 10 to achieve stacking, and sufficient space is reserved under the battery 3, so that the battery 3 can be squeezed and constrained without bottom support, which is faster and more conducive to improving production efficiency.

[0052] The pressure detection component can also detect the extrusion force on the battery 3, and in the process of controlling the extrusion stroke, avoid excessive extrusion of the battery 3 and damage to the battery 3, thereby ensuring the yield of the battery 3.

[0053] like Figure 1-3 As shown, in some embodiments provided by the present invention, the support frame structure includes columns 4, which can be specifically an even number of columns 4, such as two or four columns 4, six columns, etc. When two columns 4 are set, the two columns 4 are arranged opposite to each other, and the central position of the limit member 1 can be connected to the column 4; when four or six columns are set, they are also arranged as two opposite groups, and the corresponding positions such as the two ends and the middle of the limit member 1 are connected to the column 4; the limit members 1 are connected to the opposite sides of the two groups of columns 4, so that the slide groove structures 10 of the limit members 1 on both sides are opposite, so that the two ends of the battery 3 can slide in respectively.

[0054] In the above scheme, the limiter 1 is supported by independent columns 4, which can provide better space at the bottom of both sides, front and back sides, etc., to facilitate coordination with other equipment, facilitate staff to assemble the battery 3, and improve work efficiency.

[0055] like Figure 2-4 As shown, in some embodiments provided by the present utility model, an adjustment assembly 5 is also included; the adjustment assembly 5 includes: a first slide rail member 50, a first connecting seat 51 and a toggle clamp member 52; wherein,

[0056] The first slide rail member 50 is connected to the column 4 and provides a sliding track for the position limiting member 1; the end of the position limiting member 1 is provided with a slot that can be engaged with the sliding track, so that the position limiting member 1 can slide along the sliding track when the position limiting member 1 is restricted;

[0057] A first connecting seat 51 is connected to the column 4. A long connecting hole is provided on the first connecting seat 51 for connecting the toggle clamp component 52.

[0058] The toggle clamp component 52 is a prior art and can be a standard mechanical component on the market. The toggle clamp component 52 is connected to the first connecting seat 51, and its action end is connected to the limit member 1. The toggle clamp component 52 can drive the limit member 1 to slide along the sliding track. When the toggle clamp component 52 completes the movement, the limit member 1 reaches a clamping position adapted to the battery cell, thereby realizing the clamping of the battery cell.

[0059] In the above solution, the position of the toggle clamp component 52 can be changed through the long strip connection hole, and then by changing the position of the toggle clamp component 52, the final position of the limiter 1 can be limited; it can be applicable to batteries 3 of more sizes and has stronger adaptability.

[0060] like Figure 3 As shown, in some embodiments provided by the utility model, a top clamping mechanism 6 is also included. The top clamping mechanism 6 can be composed of columnar profiles, or a plate-like structure is selected to connect the main part of the detachable lock at the edge position, and the lock tongue part is fixed to the top edge of the support frame structure for detachable connection of the top clamping mechanism 6.

[0061] In the above scheme, when the battery 3 is clamped on the limiter 1 and stacked and limited by the side clamping mechanism 2, the top end plate 32 of the battery cell can be clamped above the battery 3 to achieve the installation of the top end plate 32 and evenly press the adhesive between the top end plate 32 and the battery cell module. When the top end plate 32 is not installed, the top clamping mechanism 6 can be not installed to avoid interference during the squeezing of the battery 3.

[0062] like Figure 1-3 As shown in , 6 , in some embodiments provided by the present invention, a bottom clamping mechanism 7 is also included. The bottom clamping mechanism 7 is arranged below the bottom plane of the limiting member 1, and its action end can reciprocate in a direction perpendicular to the bottom plane of the limiting member 1.

[0063] In the above scheme, the bottom end plate 31 can be connected at the bottom. Before installing the bottom end plate 31, it is placed in a lower position to avoid interfering with the stacking process of the battery 3. After the battery 3 is stacked and extruded, the bottom end plate 31 is pressed under the battery module through the bottom clamping mechanism 7, and the adhesive between the battery module and the bottom end plate 31 is evenly pressed to ensure a firm connection.

[0064] like Figure 1-3 As shown, in some embodiments provided by the present utility model, the side clamping mechanism 2 includes: a mounting base 20, a second slide rail member 21, a first linear drive member 23 and an extrusion end plate member 24; wherein,

[0065] The mounting base 20 can be constructed by using a plate to form a square-structured mounting base 20, with the top being a mounting plane;

[0066] Two second slide rails 21 are provided, which are respectively provided at two ends of the top of the mounting base 20, and a sliding seat 22 is slidably connected to the second slide rail 21;

[0067] A first linear drive component 23 connected to the top of the mounting base 20;

[0068] The extrusion end plate component 24 is connected to the action end of the first linear driving component 23 and is fixed to the sliding seat 22 , so that the extrusion end plate component 24 can slide along the second sliding rail component 21 .

[0069] Specifically, the first linear drive component 23 can be selected from linear modules such as a screw transmission mechanism, an electric telescopic rod device or a cylinder. A screw transmission mechanism is preferred here. A rotating connecting base is installed on the top of the mounting base 20. The screw member of the screw transmission mechanism passes through the rotating connecting base and is rotatably connected to it. A rotating handwheel is connected at the outer end, and the other end is screwed to the side wall of the extrusion end plate component 24. Rotating the rotating handwheel can control the reciprocating movement of the extrusion end plate component 24 on the screw member, and a limit stop ring 230 is set at one end of the screw member close to the extrusion end plate component 24. The detection end of the pressure detection component is set on the extrusion end plate component 24, opposite to the limit stop ring. When the extrusion end plate component 24 reciprocates on the screw member, the limit stop ring squeezes the detection end of the pressure detection component, and the pressure value changes. This pressure value is consistent with the pressure value applied to the battery 3.

[0070] Specifically, the extrusion end plate component 24 includes a clamping block 240 and an end plate limiting block 241; the clamping block 240 is fixed to the end plate limiting block 241, the clamping block 240 is screwed to the screw member of the screw transmission mechanism, and the end plate limiting block 241 is provided with a limiting pin adapted to the battery end plate 30 on the side opposite to the battery 3; after the battery 3 is loaded into the limiting component 1, it is necessary to place the battery end plate 30 with a positioning hole on the extrusion end of the end plate limiting block 241 to connect the two, and then squeeze the battery 3 to avoid damage to the battery 3.

[0071] In the above scheme, the first linear driving component 23 can be used to drive the extrusion end plate component 24 to slide back and forth along the second slide rail component 21 to stack and extrude the batteries 3, and the extrusion force on the batteries 3 can be controlled by controlling the stroke of the first linear driving component 23. This also helps to adapt to battery modules of different thicknesses, avoid damaging the batteries 3 due to excessive pressure, and enhance adaptability.

[0072] like Figure 1-3 As shown in FIG. 6 , in some embodiments provided by the present utility model, the bottom pressing mechanism 7 includes:

[0073] The second linear drive component 70 can be a synchronous lifter, an electric push rod, a cylinder or an oil cylinder, etc., and is preferably a manual synchronous lifter; the synchronous lifter is arranged below the bottom plane of the limiter 1;

[0074] A lifting plate 71 connected to the action end of the second linear driving component 70;

[0075] The limiting assembly 72 has a limiting member 1 with adjustable height, and the limiting member 1 is located above the top end surface of the lifting plate 71.

[0076] Specifically, the limit assembly 72 includes a limit column 4, a blocking member and a limit rod; the limit column 4 is arranged on one side of the second linear drive component 70, and its side wall is provided with a height scale, and a long bolt connection hole and an avoidance hole for adjusting the height are opened; the blocking member is a C-shaped structural member, which is fixed under the jacking plate 71, and the limit rod is the limit member 1 with adjustable height of the limit assembly 72, one end of which is a mounting plate and the other end is a blocking rod; the mounting plate can be connected to the limit column 4 by a bolt member, and the connection height is adjusted by the long bolt connection hole, the blocking rod passes through the avoidance hole and extends into the blocking member, and its rising height is controlled by the blocking member.

[0077] In the above scheme, the rising stroke of the lifting plate 71 can be controlled by adjusting the limit height of the limit assembly 72, thereby controlling the pressure applied to the bottom end plate 31 of the battery 3, and can be adapted to different types of battery modules according to the height, thereby improving adaptability.

[0078] like Figure 1-3 As shown, in some embodiments provided by the present utility model, the pressure detection component includes:

[0079] The pressure detection component 8 may be a known pressure sensor component, and the pressure detection component 8 is used to detect the pressure applied by the side clamping mechanism 2 to the battery 3;

[0080] The display screen 9 is electrically connected to the pressure detection component 8 and is used to display pressure data.

[0081] In the above scheme, by detecting the actual pressure on the battery 3 and controlling the extrusion stroke, damage to the battery 3 caused by excessive pressure can be avoided, the number of defective products can be reduced, and production costs can be saved.

[0082] like Figure 1-3 As shown, in some embodiments provided by the present invention, a supporting trolley 100 is also included; the trolley plate of the supporting trolley 100 can provide an installation platform for the support frame structure, the side clamping mechanism 2, the bottom clamping mechanism 7 and the display screen 9.
