[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0031] The utility model discloses a battery module stacking device. Figure 1-3A battery module stacking device comprises a processing table 3, a cylinder 1, an adjusting cylinder 2 and a positioning plate 4 are arranged on the upper part of the processing table 3, a detection mechanism 5 for detecting the size of the extrusion force on the battery module is arranged at one end of the cylinder 1, an extrusion plate 6 is arranged on one side of the detection mechanism 5, a groove 7 is opened inside the extrusion plate 6, a buffer protection mechanism 8 for protecting the battery module is arranged in the groove 7, and a limiting mechanism 9 for limiting the battery module is arranged on the adjusting cylinder 2;

[0032] Reference Figure 2 The detection mechanism 5 includes a connecting plate 501 and a pressure sensor 502. The connecting plate 501 is arranged at one end of the cylinder 1, and the pressure sensor 502 is arranged on a side of the connecting plate 501 away from the cylinder 1. The side of the pressure sensor 502 away from the connecting plate 501 is connected to the extrusion plate 6 for detecting the magnitude of the extrusion force on the battery module.

[0033] By adopting the above technical solution, the size of the squeezing force on the battery module can be known through the pressure sensor 502. Once it is found that the squeezing force is too large, the squeezing of the battery module is stopped immediately, which greatly improves the protection of the battery module.

[0034] Reference Figure 2 The buffer protection mechanism 8 includes two springs 801, a limit plate 802 and an extrusion block 803. The two springs 801 are both arranged in the groove 7. The limit plate 802 is arranged at one end of the two springs 801. The extrusion block 803 is arranged at the end of the limit plate 802 away from the spring 801, and the end of the extrusion block 803 away from the limit plate 802 passes through the groove 7.

[0035] By adopting the above technical solution, before the extrusion plate 6 contacts the battery module, the extrusion block 803 will first contact the corresponding battery module and squeeze the spring 801, and then as the extrusion block 803 squeezes the spring 801, it gradually moves into the groove 7. At this time, the extrusion plate 6 will contact the corresponding battery module and squeeze multiple battery modules, so that the impact force of the extrusion plate 6 on the battery module can be reduced by the elastic deformation of the spring 801, thereby avoiding damage or deformation of the battery module due to excessive extrusion force or too fast movement of the extrusion plate 6, thereby further improving the protection of the battery module.

[0036] Reference Figure 3The limiting mechanism 9 includes a bidirectional screw 901, two threaded sleeves 902, two baffles 903 and a handle 904. The bidirectional screw 901 is rotatably arranged inside the adjusting cylinder 2. The two threaded sleeves 902 are both threadedly connected to the bidirectional screw 901, and one end of the threaded sleeve 902 away from the bidirectional screw 901 passes through the interior of the adjusting cylinder 2. The two baffles 903 are respectively arranged at one end of the corresponding threaded sleeve 902 for limiting the battery module. The handle 904 is rotatably arranged on one side of the adjusting cylinder 2, one end of which passes through the interior of the adjusting cylinder 2 and is connected to one end of the bidirectional screw 901 for driving the bidirectional screw 901 to rotate.

[0037] By adopting the above technical solution, rotating the handle 904 drives the bidirectional screw 901 to rotate. The rotation of the bidirectional screw 901 can drive the two threaded sleeves 902 to approach each other, and then drive the two baffles 903 to approach each other until the front and rear sides of the battery module contact one side of the two baffles 903, so that multiple battery modules are not easily offset when stacked.

[0038] Reference Figure 1 T-shaped plates 10 are provided on the front and rear sides of the positioning plate 4 and the extrusion plate 6. The left T-shaped plate 10 passes through the corresponding baffle 903, and a guide opening 11 is opened on the baffle 903. One end of the right T-shaped plate 10 passes through the guide opening 11 and is slidably connected to the guide opening 11.

[0039] By adopting the above technical solution, the stability of the extrusion plate 6 during movement is ensured through the cooperation of the T-shaped plate 10 and the guide opening 11 .

[0040] Working principle: When the utility model is in use, the electrical components appearing in the present application are all externally connected to the power supply and the control switch. First, one of the battery modules is placed on the processing table 3 and its left end is in contact with the positioning plate 4. Then, the handle 904 is turned to drive the bidirectional screw 901 to rotate. The rotation of the bidirectional screw 901 can drive the two threaded sleeves 902 to approach each other, and then the two baffles 903 can be driven to approach each other until the front and rear sides of the battery module are in contact with one side of the two baffles 903. Then, thermal conductive glue is applied to the right end of the battery module. After that, multiple battery modules coated with thermal conductive glue can be directly stacked and placed in sequence. At this time, the two baffles 903 can limit the position of multiple battery modules, so that the multiple battery modules are not easy to deviate when stacked. Then, the cylinder 1 works to drive the extrusion plate 6 to move, and the extrusion The movement of the pressure plate 6 causes the extrusion block 803 to first contact the corresponding battery module and squeeze the spring 801, and then as the extrusion block 803 squeezes the spring 801, it gradually moves into the groove 7. At this time, the extrusion plate 6 will contact the corresponding battery module and squeeze multiple battery modules, so that the elastic deformation of the spring 801 can reduce the impact force of the extrusion plate 6 on the battery module, thereby avoiding damage or deformation of the battery module due to excessive extrusion force or too fast movement of the extrusion plate 6, thereby greatly improving the protection of the battery module. At the same time, when the extrusion plate 6 squeezes the battery module, the pressure sensor 502 can be used to know the size of the extrusion force on the battery module. Once it is found that the extrusion force is too large, the extrusion of the battery module is stopped immediately, which further improves the protection of the battery module.

[0041] When the utility model is in use, when a plurality of stacked battery modules are squeezed, damage or deformation of the battery modules caused by excessive squeezing force or too fast movement of the squeezing plate 6 can be avoided. At the same time, the size of the squeezing force on the battery module can be detected, thereby greatly improving the protection of the battery module.
