When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0039] In electric vehicles and most portable electronic devices, the PACK battery pack is a key component. It consists of multiple battery cells, which are usually encapsulated in a container or housing to protect them from physical damage and environmental factors.

[0040] The assembly of the battery pack generally includes a module stacking section, a module welding section, and a PACK assembly section. During the PACK assembly section, a gluing operation needs to be performed on the PACK battery pack. However, the existing gluing devices have the problem of low gluing efficiency.

[0041] The present utility model proposes a gluing device for a battery pack.

[0042] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the gluing device for the battery pack includes a first gluing unit 100 and a second gluing unit 200. The first gluing unit 100 includes a first gluing assembly 110, and the first gluing assembly 110 includes a first gluing gun 111, which is used for gluing the battery pack; the second gluing unit 200 includes a second gluing assembly 210, and the second gluing assembly 210 includes a second gluing gun 211, which is used for gluing the battery pack; wherein, the first gluing unit 100 can move relative to the second gluing unit 200 to adjust the distance between the first gluing gun 111 and the second gluing gun 211.

[0043] Specifically, two gluing units are provided in the battery pack gluing device, namely the first gluing unit 100 and the second gluing unit 200. The two gluing units can perform gluing operations on the battery pack simultaneously. The first gluing unit 100 includes a first gluing assembly 110. The first gluing gun 111 in the first gluing assembly 110 contains glue, and the battery pack is glued through the glue outlet of the first gluing gun 111. Similarly, the second gluing unit 200 glues the battery pack through the second gluing gun 211. It can be understood that a battery pack generally has two or more battery modules. When performing the gluing operation, while the first gluing gun 111 glues one battery module, the second gluing gun 211 can glue another battery module. In this way, the gluing efficiency of the battery pack can be improved, and the gluing time of the battery pack can be saved.

[0044] Furthermore, the first gluing unit 100 can move relative to the second gluing unit 200, that is, the first gluing unit 100 can approach or move away from the second gluing unit 200, so as to adjust the distance between the first gluing gun 111 and the second gluing gun 211, that is, to adjust the distance between the two glue outlets. It can be understood that the sizes of battery packs are different, and the sizes of battery modules are different, so that the distances between any two battery modules in different battery packs are different. Therefore, when gluing different battery packs, the distances between the first gluing gun 111 and the second gluing gun 211 are different. The adjustable distance between the first gluing gun 111 and the second gluing gun 211 enables the battery pack gluing device to be applicable to different battery packs, improving the applicable range of the battery pack gluing device.

[0045] The technical solution of the present utility model is to provide the first gluing unit 100 and the second gluing unit 200 in the battery pack gluing device. The first gluing unit 100 includes a first gluing assembly 110, the first gluing assembly 110 includes a first gluing gun 111, the second gluing unit 200 includes a second gluing assembly 210, the second gluing assembly 210 includes a second gluing gun 211, and both the first gluing gun 111 and the second gluing gun 211 are used to glue the battery pack. At the same time, the first gluing unit 100 can also move relative to the second gluing unit 200 to adjust the distance between the first gluing gun 111 and the second gluing gun 211. In this way, on the one hand, compared with the prior art solution of only providing one gluing gun, two gluing guns are provided in the present utility model, and the two gluing guns can glue the battery pack simultaneously, thus improving the gluing efficiency; on the other hand, the distance between the first gluing gun 111 and the second gluing gun 211 is adjustable, enabling the battery pack gluing device to perform gluing operations on different battery packs and improving the applicable range of the battery pack gluing device.

[0046] In an embodiment of the present utility model, the first glue - applying assembly 110 further includes a first carrier plate 112, and a first glue - applying gun 111 is installed on the first carrier plate 112. The second glue - applying assembly 210 further includes a second carrier plate 212, and a second glue - applying gun 211 is installed on the second carrier plate 212. The first glue - applying unit 100 and the second glue - applying unit 200 are connected by a fixing plate 300. The first glue - applying unit 100 further includes a distance - adjusting assembly 140. The distance - adjusting assembly 140 includes a rocker 141 and an adjusting block 142. The adjusting block 142 is sleeved on the rocker 141. An adjusting groove 310 is provided on the fixing plate 300. One side of the adjusting block 142 is slidably installed in the adjusting groove 310, and the other side is connected to the first carrier plate 112. When the rocker 141 rotates, the adjusting block 142 can slide along the adjusting groove 310 to drive the first carrier plate 112 to move, thereby adjusting the distance between the first glue - applying gun 111 and the second glue - applying gun 211.

[0047] Specifically, please refer to Figures 1 to 3 , the first glue - applying assembly 110 further includes a first carrier plate 112, and the first glue - applying gun 111 is installed on the first carrier plate 112. The second glue - applying assembly 210 further includes a second carrier plate 212, and the second glue - applying gun 211 is installed on the second carrier plate 212. The first glue - applying unit 100 and the second glue - applying unit 200 are connected by a fixing plate 300. More specifically, the first carrier plate 112 and the second carrier plate 212 are installed on the fixing plate 300 at intervals from each other, thereby realizing the connection of the first glue - applying unit 100 and the second glue - applying unit 200. In one embodiment, the first glue - applying unit 100 is a movable member, and the second glue - applying unit 200 is a stationary member. The first glue - applying unit 100 can approach or move away from the second glue - applying unit 200, thereby adjusting the distance between the first glue - applying gun 111 and the second glue - applying gun 211.

[0048] To realize the movability of the first glue - applying unit 100, the first glue - applying unit 100 further includes a distance - adjusting assembly 140. The distance - adjusting assembly 140 includes a rocker 141 and an adjusting block 142, wherein the adjusting block 142 is sleeved on the rocker 141. In one embodiment, the rocker 141 is configured as a threaded rod, and a through - hole is provided on the adjusting block 142. Threads are provided on the inner wall of the through - hole, and the adjusting block 142 is threadedly connected to the rocker 141. When the rocker 141 rotates, the adjusting block 142 can move along the axial direction of the rocker 141. For the convenience of description, the axial direction of the rocker 141 is defined as the first direction (such as Figure 1As shown in the figure, the first glue application unit 100 and the second glue application unit 200 are arranged at intervals along the first direction. The fixing plate 300 is provided with an adjustment groove 310 on one side of the first glue application unit 100. One side of the adjustment block 142 is embedded in the adjustment groove 310 and can slide in the adjustment groove 310. In the first direction, the adjustment groove 310 has a certain length to ensure the sliding stroke of the adjustment block 142. It can be understood that the length range of the adjustment groove 310 is the movable stroke range of the first glue application unit 100. The other side of the adjustment block 142 is connected to the first carrier plate 112. In an embodiment, the adjustment block 142 is connected to the first carrier plate 112 by bolts.

[0049] In this way, when the rocker 141 is rotated, the adjustment block 142 moves along the axial direction of the rocker 141 and slides within the range of the adjustment groove 310, while driving the first carrier plate 112 to move along the first direction, and further driving the first glue gun 111 to move along the first direction, so as to adjust the distance between the first glue gun 111 and the second glue gun 211.

[0050] In an embodiment, the distance adjustment assembly 140 is configured to be manually controlled, that is, the rocker 141 is rotated by manual operation. Of course, in other embodiments, the distance adjustment assembly 140 can also be driven by a servo motor.

[0051] In the embodiment of the present utility model, the distance adjustment assembly 140 further includes a linear module 143. The linear module 143 is installed on the fixing plate 300, and the output end of the linear module 143 is connected to the first carrier plate 112.

[0052] Specifically, please refer to Figure 1 and Figure 3 The distance adjustment assembly 140 further includes a linear module 143. The linear module 143 extends along the first direction, that is, the axial direction of the linear module 143 is parallel to the axial direction of the rocker 141. The linear module 143 is installed on the fixing plate 300, and the output end of the linear module 143 is connected to the first carrier plate 112. In this way, when the rocker 141 is rotated and the adjustment block 142 drives the first carrier plate 112 to move along the first direction, the linear module 143 can also drive the first carrier plate 112 to move along the first direction, thereby avoiding the situation of unstable movement caused by only relying on the adjustment block 142 to drive the first carrier plate 112 to move and further driving the first glue application unit 100 to move, improving the reliability of the movement of the first glue application unit 100, and further improving the use reliability of the battery pack glue application device.

[0053] In the embodiment of the present utility model, there are two linear modules 143, and the two linear modules 143 are respectively arranged on opposite sides of the rocker 141.

[0054] Specifically, please refer to Figure 1 andFigure 3 In one embodiment, two linear modules 143 are provided. The two linear modules 143 both extend along the first direction. The two linear modules 143 are respectively mounted on the fixing plate 300. The output ends of the two linear modules 143 are respectively connected to the first carrier plate 112, and the two linear modules 143 are respectively arranged on opposite sides of the rocker 141. In this way, the movement stability and balance of the first gluing unit 100 are improved.

[0055] In an embodiment of the present utility model, the first gluing unit 100 further includes a first glue receiving assembly 120. The first glue receiving assembly 120 includes a first glue receiving box 121. The first glue receiving box 121 can extend or retract relative to the glue outlet of the first glue gun 111; and / or, the second gluing unit 200 further includes a second glue receiving assembly 220. The second glue receiving assembly 220 includes a second glue receiving box 221. The second glue receiving box 221 can extend or retract relative to the glue outlet of the second glue gun 211.

[0056] Specifically, please refer to Figure 1 and Figure 2 In one embodiment, the first gluing unit 100 further includes a first glue receiving assembly 120. The first glue receiving assembly 120 includes a first glue receiving box 121. The first glue receiving box 121 can extend or retract relative to the glue outlet of the first glue gun 111. It can be understood that the first glue gun 111 has a working state and a non-working state. In the working state, the first glue gun 111 discharges glue through its glue outlet to glue the battery pack; in the non-working state, the glue outlet of the first glue gun 111 does not discharge glue. In order to prevent the glue outlet of the first glue gun 111 from dripping glue onto the battery pack or other components in the non-working state, a first glue receiving box 121 is configured in the first gluing unit 100. When the first glue gun 111 is in the non-working state, the first glue receiving box 121 extends relative to the glue outlet of the first glue gun 111 to be located below the glue outlet of the first glue gun 111 for receiving the glue dripping from the first glue gun 111. When the first glue gun 111 is in the working state, the first glue receiving box 121 retracts relative to the glue outlet of the first glue gun 111 to avoid interfering with the normal operation of the first glue gun 111.

[0057] In one embodiment, the second gluing unit 200 further includes a second glue receiving assembly 220. The second glue receiving assembly 220 includes a second glue receiving box 221. The second glue receiving box 221 can extend or retract relative to the glue outlet of the second glue gun 211. The structure and working principle of the second glue receiving box 221 are the same as those of the first glue receiving box 121, and will not be described in detail here.

[0058] In an embodiment of the present utility model, the first glue receiving assembly 120 further includes a first lifting cylinder 122 and a first horizontal cylinder 123. The first lifting cylinder 122 is located on the side of the fixing plate 300 away from the first glue applying assembly 110 and is connected to the adjusting block 142. The first horizontal cylinder 123 is connected to the output end of the first lifting cylinder 122, and the first glue receiving box 121 is connected to the output end of the first horizontal cylinder 123; and / or, the second glue receiving assembly 220 further includes a second lifting cylinder 222 and a second horizontal cylinder 223. The second lifting cylinder 222 is installed on the side of the fixing plate 300 away from the second glue applying assembly 210. The second horizontal cylinder 223 is connected to the output end of the second lifting cylinder 222, and the second glue receiving box 221 is connected to the output end of the second horizontal cylinder 223.

[0059] Specifically, please refer to Figure 1 and Figure 2 To realize the extension and retraction of the first glue receiving box 121, the first glue receiving assembly 120 includes a first lifting cylinder 122 and a first horizontal cylinder 123. For the convenience of description, the movement direction of the first lifting cylinder 122 is defined as the second direction, and the movement direction of the first horizontal cylinder 123 is defined as the third direction. The first lifting cylinder 122 is located on the side of the fixing plate 300 away from the first glue applying assembly 110, and the first lifting cylinder 122 is further connected to the adjusting block 142 through a connecting plate, so that the first lifting cylinder 122 can move along with the movement of the adjusting block 142. Furthermore, the first glue receiving assembly 120 can move along with the movement of the adjusting block 142, so that the movement of the first glue receiving assembly 120 is consistent with that of the first glue applying assembly 110, and the movement of the first glue receiving box 121 is consistent with that of the first glue gun 111, so that the first glue receiving box 121 is always arranged close to the first glue gun 111 for convenient glue receiving.

[0060] The first horizontal cylinder 123 is connected to the output end of the first lifting cylinder 122, and the first glue receiving box 121 is connected to the output end of the first horizontal cylinder 123. Thus, when the first glue receiving box 121 switches from the retracted state to the extended state, the output end of the first lifting cylinder 122 moves downward in the second direction, driving the first horizontal cylinder 123 and the first glue receiving box 121 to move downward in the second direction. When the first lifting cylinder 122 moves in place in the second direction, the first lifting cylinder 122 stops working. At this time, the first horizontal cylinder 123 starts to move forward in the third direction, driving the first glue receiving box 121 to also move forward in the third direction. When the first glue receiving box 121 is located below the glue outlet of the first glue gun 111, the first horizontal cylinder 123 stops working. When the first glue receiving box 121 switches from the extended state to the retracted state, the first glue receiving box 121 moves backward in the third direction under the drive of the first horizontal cylinder 123. After moving in place, the first glue receiving box 121 then moves upward in the second direction under the drive of the first lifting cylinder 122 to avoid interfering with the normal operation of the first glue gun 111.

[0061] In one embodiment, the second glue receiving assembly 220 further includes a second lifting cylinder 222 and a second horizontal cylinder 223. The specific structures and working processes of the second lifting cylinder 222 and the second horizontal cylinder 223 are the same as those of the first lifting cylinder 122 and the first horizontal cylinder 123. The difference is that the second lifting cylinder 222 is installed on the side of the fixed plate 300 away from the second glue applying assembly 210. The specific structures and working processes of the second lifting cylinder 222 and the second horizontal cylinder 223 will not be elaborated here.

[0062] It should be noted that the working control logics of the first lifting cylinder 122, the first horizontal cylinder 123, the second lifting cylinder 222, and the second horizontal cylinder 223 belong to the prior art and will not be elaborated here.

[0063] In the embodiment of the present utility model, the first glue applying assembly 110 further includes a first claw 113, and the first claw 113 is clamped between the two ends of the first glue gun 111; and / or, the second glue applying assembly 210 further includes a second claw 213, and the second claw 213 is clamped between the two ends of the second glue gun 211.

[0064] Specifically, please refer to Figure 1, the first glue - applying assembly 110 further includes a first claw 113, and the first claw 113 is clamped between two ends of the first glue - applying gun 111. The first glue - applying gun 111 has two ends along its length direction. One end is the glue outlet, and the other end is fixed and communicated with the mixing tube. There is also a first claw 113 between the two ends of the first glue - applying gun 111. The first claw 113 is connected to the first bearing plate 112, and the first claw 113 is used for clamping between the two ends of the first glue - applying gun 111. In one embodiment, the first claw 113 clamps the middle part of the first glue - applying gun 111, and the specific clamping position of the first claw 113 is not limited here. The clamping of the first claw 113 improves the installation stability of the first glue - applying gun 111 and also avoids the offset of the first glue - applying gun 111 in the second direction, thus ensuring the accuracy of the glue - applying position.

[0065] In one embodiment, the second glue - applying assembly 210 further includes a second claw 213, and the second claw 213 is clamped between two ends of the second glue - applying gun 211. The structure of the second claw 213 is the same as that of the first claw 113, and will not be described in detail here.

[0066] In an embodiment of the present utility model, a first adjustment screw 114 is installed on the first claw 113 to adjust the clamping tightness of the first claw 113; and / or, a second adjustment screw 214 is installed on the second claw 213 to adjust the clamping tightness of the second claw 213.

[0067] Specifically, please refer to Figure 1 , a first adjustment screw 114 is installed on the first claw 113, and the first adjustment screw 114 can adjust the clamping tightness of the first claw 113.

[0070] Specifically, please refer to Figure 1 and Figure 2 The first glue - applying unit 100 further includes a first detection component 130. The first detection component 130 is used to detect the glue - applying trajectory of the first glue - applying gun 111. After the first glue - applying gun 111 finishes applying glue to the battery pack, the first detection component 130 detects the glue - applying trajectory of the first glue - applying gun 111 and determines whether its glue - applying trajectory is consistent with the preset glue - applying route, so as to determine whether the glue - applying of the battery pack is qualified. The first detection component 130 is connected to the first glue - applying component 110. In one embodiment, the first detection component 130 is connected to the first glue - applying component 110 through a first connection frame 134. One end of the first connection frame 134 is connected to the first carrier plate 112, and the other end of the first connection frame 134 is connected to the first detection component 130, so that the first detection component 130 can move along with the movement of the first glue - applying component 110, thereby realizing the overall movement of the first glue - applying unit 100.

[0071] In one embodiment, the second glue - applying unit 200 further includes a second detection component 230.

One end of the second connection frame 234 is connected to the second carrier plate 212, and the other end of the second connection frame 234 is connected to the second detection component 230.

[0072] In an embodiment of the present utility model, the first detection component 130 includes a first frame 131.

The second camera 232 is used to photograph the glue - applying trajectory of the second glue - applying gun 211, and the second light source 233 is used to provide light for the second camera 232.

[0073] Specifically, please refer toFigure 1 and Figure 2 , the first detection component 130 includes a first frame 131, on which a first camera 132 and a first light source 133 are installed. The first frame 131 is connected to one end of the first connection frame 134 away from the first carrier plate 112 to realize the connection between the first detection component 130 and the first glue application component 110. In an embodiment, the first camera 132 is installed at the central position of the first frame 131, and the first light source 133 is installed on the side frames of the first frame 131 along the third direction. The first light source 133 can be an LED light strip or the like. Along the second direction, the first light source 133 is installed below the side frame of the first frame 131, and at the same time, the shooting direction of the first camera 132 also faces downwards, so that the first light source 133 provides light for the shooting of the first camera 132. When detecting the glue application trajectory of the first glue gun 111, the first camera 132 takes pictures of the glue application trajectory of the first glue gun 111 and compares it with the preset glue application route to determine whether the glue application of the battery pack is qualified.

[0074] In an embodiment, the second detection component 230 includes a second frame 231, on which a second camera 232 and a second light source 233 are installed.
