With the continuous expansion of the application field of the power battery, the market demand is also continuously expanding.

The inventor notices that when the cooling plate is assembled with the frame FDS screw at the bottom of the battery box body in the process of producing the box body of the battery pack, the cooling plate has certain elasticity in a natural state, and the cooling plate is easy to elastically deform in the process of connecting the FDS, so that a large gap exists between the cooling plate and the frame FDS after the cooling plate and the frame FDS are connected, and further the airtight leakage of the battery pack box body occurs. The airtight leakage of the battery pack box body can cause the battery to be in an unsealed state, and the performance and the service life of the battery can be adversely affected, so that the electric quantity of the battery can be reduced for a long time, and the battery monomer which is not normally sealed can be damaged due to the permeation of atmospheric humidity.

In order to solve the problem of air-tight leakage of the battery pack case, the applicant has studied and found that the cooling plate may be fixed during FDS screw assembly of the cooling plate and the battery case to reduce a gap between the cooling plate and the battery case. Specifically, can adsorb the cooling plate downwards through vacuum chuck for in-process that carries out FDS screw assembly to cooling plate and battery box, cooling plate and battery box laminating, in order to realize improving among the prior art the easy airtight problem of leaking of battery package box.

The battery tray gluing and nailing equipment and the positioning device thereof disclosed by the embodiment of the application can be applied to the production process of various battery pack boxes.

As shown in fig. 1 and 2, a positioning device 100 for positioning a battery case 201 and a cooling plate 202 is shown according to an embodiment of the present application. The positioning device 100 includes a base plate 110, a vacuum chuck 120, a support 130, and a fixture 140. The vacuum chuck 120 serves to vertically suck the cooling plate 202, and the vacuum chuck 120 is connected to the base plate 110. The plurality of supporting members 130 are used to vertically support the cooling plate 202, the supporting members 130 are connected to the base plate 110, and the supporting members 130 are distributed on both sides of the vacuum chuck 120 in the transverse or longitudinal direction and are vertically lower than the vacuum chuck 120. The fixing device 140 is used for laterally and/or longitudinally limiting the battery case 201 and/or the cooling plate 202, and the fixing device 140 is connected to the bottom plate 110.

It should be noted that, the vertical direction, the transverse direction and the longitudinal direction are three mutually perpendicular directions, and it can be understood by using an XYZ spatial rectangular coordinate system, and the transverse direction, the longitudinal direction and the vertical direction respectively correspond to the directions of the X, Y, Z axes.

It should be noted that the battery case 201 is a three-dimensional hollow structure and is used for accommodating a battery module. The cooling plate 202 is located inside the battery case 201, and the cooling plate 202 may be attached to the bottom surface of the battery case 201 by FDS screws. The bottom surface of the battery case 201 is provided with a plurality of through grooves that allow the cooling plate 202 to contact the outside of the battery case 201.

It is understood that the vacuum chuck 120, the support member 130 and the fixing device 140 are all connected to the base plate 110 in a fixed or detachable manner. In this embodiment, the vacuum chuck 120, the supporter 130 and the fixing device 140 are connected to the base plate 110 by screws.

As shown in fig. 2, the number of the vacuum cups 120 may be plural, and the plurality of vacuum cups 120 are uniformly arranged and coupled to the base plate 110. The vacuum chuck 120 functions to vertically suck the cooling plate 202, that is, the sucking cooling plate 202 moves toward the bottom plate 110. In the embodiment shown in fig. 2, the vacuum chuck 120 is vertically connected to the bottom plate 110, and in the process that the battery box 201 and the cooling plate 202 are placed on the positioning device 100 from top to bottom, the vacuum chuck 120 passes through a through groove formed in the battery box 201 and contacts with the cooling plate 202, and a closed space is formed between the vacuum chuck 120 and the cooling plate 202, and the vacuum chuck 120 generates a downward pulling force on the cooling plate 202 by vacuumizing the space.

As shown in fig. 1, a support 130 is provided at both sides of each vacuum chuck 120. The supporting member 130 is used for providing a force to the cooling plate 202 opposite to the force applied by the vacuum chuck 120 to the cooling plate 202, so as to prevent the cooling plate 202 from being deformed and protruded outwards relative to the battery case 201 due to the excessive pulling force of the vacuum chuck 120. It will be appreciated that the height setting of the support 130 requires two considerations: on one hand, the cooling plate 202 can be attached to the surface of the battery box 201 after being pulled down by the vacuum chuck 120; on the other hand, when the cooling plate 202 is supported by the support 130, the cooling plate 202 is not significantly deformed.

In the embodiment shown in fig. 1, the vacuum chuck 120 generates a downward pulling force on the cooling plate 202, and the support 130 can generate an upward supporting force on the cooling plate 202, so that when the cooling plate 202 reaches a position contacting with the support 130, the supporting force of the support 130 on the cooling plate 202 can be used to balance the pulling force of the vacuum chuck 120 on the cooling plate 202, thereby achieving a vertical position-limiting effect on the cooling plate 202 by the support 130.

The fixing device 140 is used for laterally and/or longitudinally limiting the battery case 201 and/or the cooling plate 202, and specifically, the fixing device 140 may be used for laterally limiting the battery case 201, may also be used for longitudinally limiting the battery case 201, may also be used for laterally limiting the cooling plate 202, and may also be used for longitudinally limiting the cooling plate 202. After the battery box 201 and the cooling plate 202 are limited and fixed by the fixing device 140, the battery box 201 and the cooling plate 202 are relatively fixed in the transverse and longitudinal positions, so that the situation that the sealing performance of the FDS connection is affected by the fact that the cooling plate 202 moves relative to the battery box 201 in the FDS connection process and the sealing effect of the battery box 201 is affected is avoided.

As shown in fig. 2, when the positioning device 100 is used to position the battery box 201 and the cooling plate 202, the battery box 201 and the cooling plate 202 need to be placed on the positioning device 100 from top to bottom, and the battery box 201 and the cooling plate 202 are limited in the transverse direction and the longitudinal direction by the fixing device 140. After the placement, as shown in fig. 2, since the height of the vacuum chuck 120 is higher than that of the support 130, the cooling plate 202 (in the dotted line state) is naturally pressed above the vacuum chuck 120, the vacuum chuck 120 contacts with the cooling plate 202 and forms a closed space between the vacuum chuck 120 and the cooling plate 202, and the cooling plate 202 is moved downward to a position contacting with the support 130 by applying a downward pulling force to the cooling plate 202 by the vacuum chuck 120 by evacuating the space, at which time the cooling plate 202 is in the solid line state as shown in fig. 2.

In the above solution, by providing the supporting members 130 on both sides of the vacuum chuck 120, the distance that the cooling plate 202 moves downward by the vacuum chuck 120 is limited by the supporting members 130, so that the lowest position where the cooling plate 202 can be located is a position in contact with the supporting members 130. By adopting the arrangement mode, the purpose of attaching the cooling plate 202 to the battery box body 201 by downwards adsorbing the cooling plate 202 through the vacuum chuck 120 can be achieved, the cooling plate 202 can be prevented from deforming due to overlarge pulling force of the vacuum chuck 120, the attaching degrees of the cooling plate 202 and the battery box body 201 in the box body produced in the same batch can be consistent, and the production management and the quality control are facilitated.

Referring to fig. 3, according to some embodiments of the present disclosure, optionally, the bottom plate 110 includes a central attaching area 111 and a fixing area 112 located around the attaching area 111, the vacuum chuck 120 and the supporting member 130 are located in the attaching area 111, and the fixing device 140 is located in the fixing area 112.

As shown in FIG. 3, the conformable region 111 and the fixed region 112 are shown separated by dashed lines. The attaching area 111 and the fixing area 112 are merely provided as a division of the functional area of the base plate 110 to illustrate the relative positions of the fixing device 140 and the vacuum chuck 120 and the support 130, and there is no need to have a division of the actual position on the base plate 110. In an embodiment, the attachment region 111 and the securing region 112 may be integrally formed.

As shown in fig. 3, the fixing device 140 is located at the fixing area 112, that is, the fixing device 140 is located at the periphery of the vacuum chuck 120 and the support 130, and the fixing device 140 surrounds all the vacuum chuck 120 and the support 130. The fixing device 140 is used for limiting the battery case 201 and the cooling plate 202, and can fix the position of the battery case 201 and limit the cooling plate 202 transversely and longitudinally before the vacuum chuck 120 adjusts the cooling plate 202 or when the cooling plate 202 is adjusted. The fixing device 140 mainly acts on the edge portions of the battery case 201 and the cooling plate 202.

By distributing the fixing devices 140 around the vacuum chucks 120 and the supporting members 130, the fixing devices 140 can act on the edge portions of the battery box 201 and the cooling plate 202, so that the fixing devices 140 can limit the battery box 201 and the cooling plate 202 before the vacuum chucks 120 adjust the cooling plate 202 and when the cooling plate 202 is adjusted, and the limit of the fixing devices 140 on the battery box 201 and the cooling plate 202 is not interfered by the adjustment of the vacuum chucks 120 on the cooling plate 202.

Referring to fig. 1 and 2, according to some embodiments of the present application, optionally, the positioning device 100 further includes a supporting block 150 for vertically supporting the battery box 201, and the supporting block 150 is connected to the bottom plate 110 and located in the attaching region 111.

The supporting shoe 150 is used for supporting the bottom of battery box 201, and the height and the setting position of supporting shoe 150 can set up according to the bottom structure of battery box 201, can adjust with the battery box 201 of adaptation in different specifications, different grade type according to the bottom structure of battery box 201.

When the battery case 201 is supported by the support block 150, the surface of the battery case 201 contacting the cooling plate 202 may be slightly higher than or equal to the height of the support member 130, so as to avoid the vacuum nozzle being restricted by the height of the support member 130 from being able to adjust the cooling plate 202 to a state of being attached to the battery case 201.

In this embodiment, as shown in fig. 2, the bottom end of the battery case 201 may be provided with legs having a certain height, and the support block 150 is lower than the support member 130 for supporting the legs.

Through the supporting block 150 for supporting the battery box 201, the battery box 201 is fixed in position in the vertical direction, the battery box 201 keeps static relative to the bottom plate 110 when the vacuum chuck 120 moves the cooling plate 202, and the situation that the fit degree between the cooling plate 202 and the battery box 201 is uncontrollable due to the fact that the battery box 201 moves synchronously is avoided.

Referring to fig. 4, according to some embodiments of the present disclosure, optionally, the fixing device 140 includes a plurality of clamping members 141 for clamping the battery box 201, and a clamping groove 1411 is formed on a side of each clamping member 141 facing the vacuum chuck 120.

As shown in fig. 4, the holding groove 1411 may include a single opening facing one side of the vacuum chuck 120, and a plurality of holding members 141 are distributed around the attaching region 111 as shown in fig. 3 to hold the edge of the battery case 201 laterally and longitudinally to limit the battery case 201. The height and the opening size of the clamping groove 1411 can be adjusted according to the edge height of the battery box body 201, and the height of the clamping piece 141 can also be adjusted according to the height of the battery box body 201, so that the clamping piece 141 can also vertically support the edge of the battery box body 201.

Through setting up holder 141 centre gripping battery box 201, transversely and vertically spacing to battery box 201 through centre gripping groove 1411 for battery box 201 is horizontal and vertical rigidity, and battery box 201 keeps static relatively bottom plate 110 when making vacuum chuck 120 remove cooling plate 202, avoids battery box 201 to rock and causes cooling plate 202 and battery box 201 laminating to appear the deviation.

Specifically, two guiding and limiting devices 142 which are arranged oppositely in the transverse direction can be abutted against the cooling plate 202 in the transverse direction and can transversely clamp the cooling plate 202; two longitudinally opposed guide and stop means 142 are capable of longitudinally abutting the cooling plate 202 and longitudinally clamping the cooling plate 202. In this embodiment, the two pairs of guiding and limiting devices 142 are horizontally disposed, and the two pairs of guiding and limiting devices 142 are distributed dispersedly and vertically disposed and include a pair of guiding and limiting devices 142.

The cooling plate 202 is transversely and longitudinally clamped by arranging the guide limiting device 142, so that the cooling plate 202 is only vertically moved when the vacuum suction nozzle adjusts the cooling plate 202, and the deviation caused by the attachment of the cooling plate 202 and the battery box 201 is avoided.
