Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly equipment for battery modules, in particular to an independent positioning and grabbing fixture for battery modules. Background Art

[0002] With the increasing awareness of environmental protection, new energy has become the focus of global energy development. The development of new energy vehicles is becoming more and more popular, which has brought huge market demand for new energy vehicle battery modules. Manual assembly has long been unable to meet the demand. Automated assembly can improve production efficiency and reduce costs, and is an indispensable part of the overproduction of new energy vehicles.

[0003] During the automatic assembly of battery modules, the battery cells need to be grasped and prevented multiple times. Traditional robot grippers need to grasp the battery cells one by one during the grasping process, which is not only inefficient, but also lacks positioning, resulting in a lot of misalignment of the battery cells during the stacking process of the final battery module, resulting in poor overall module quality. At present, the grasping of battery modules is basically simultaneous grasping and placement. It is not possible to independently pick up and place a single battery cell. In addition, the battery cell is directly grasped by the cylinder, and the position accuracy of the battery cell cannot be guaranteed during multiple pick-ups and placements. However, with the development of battery module technology, the requirements for module stacking accuracy are getting higher and higher, and the formula of battery cell configuration is becoming more and more complicated. It is necessary to grasp the battery cells at the same time and then place the battery cells independently according to the formula requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a battery module independent positioning gripping fixture. The utility model uses a clever mechanism design to meet the requirements of grabbing multiple battery cells at one time, placing a single battery cell independently, and independently positioning the battery cells. To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0005] A battery module independent positioning and grasping fixture comprises a plurality of independent lifting units and clamping units connected to the lifting units.

[0006] Furthermore, it also includes a top fixing plate, and side plates are arranged on both sides of the top fixing plate. The side plates are provided with multiple sets of slide rails, and the slide rails are provided with sliding blocks that cooperate with them. The sliding blocks are fixedly connected to the upper plate of the clamping unit.

[0007] Furthermore, the lifting cylinder of the lifting unit is fixed on a horizontal plate arranged between the middle parts of the side plates, and the lifting cylinder passes through the horizontal plate and is fixed.

[0008] Furthermore, the clamping unit includes a lower plate fixed to the lower side of the upper plate, a clamping cylinder is fixedly arranged on the lower side of the lower plate, and also includes clamping arms respectively connected to the clamping cylinders, and the clamping arms can be the upper left plate and the upper right plate connected to the clamping cylinders.

[0009] Furthermore, the clamping unit includes a lower plate fixed to the lower side of the upper plate, a clamping cylinder is fixedly arranged on the lower side of the lower plate, and also includes a left upper plate and a right upper plate respectively connected to the clamping cylinder. A left vertical plate perpendicular to the left upper plate is arranged at the other end, and a right vertical plate perpendicular to the right upper plate is arranged at the other end, and a clamping area is formed between the left vertical plate and the right vertical plate.

[0010] Furthermore, an insulating soft material cushion layer is arranged on the lower side of the upper left plate and the upper right plate, and an insulating soft material cushion layer is arranged on the inner side of the left vertical plate and the right vertical plate to prevent conduction and prevent the battery core from being damaged.

[0011] Furthermore, two sections of second slide rails are respectively arranged on both sides of the clamping cylinder on the lower side of the lower plate, and a second slider is arranged on the second slide rail. The lower end of the second slider is fixedly connected to the left upper plate or the right upper plate, and the second slider is slidably connected to the second slide rail.

[0012] Furthermore, in order to ensure the positioning of the battery cell after multiple pick-ups and placements, a pin positioning mechanism is added to the clamp arm, and the pin is inserted into the pin hole during grabbing to ensure the positioning accuracy of the clamp arm.

[0013] Furthermore, the pin positioning mechanism includes a pin positioning block arranged on the upper side of the right upper plate, and a pin is vertically installed on the pin positioning block, and the pin passes through the right upper plate.

[0014] Furthermore, centering positioning strips are arranged on the relatively inner end surfaces of the left upper plate and the right upper plate, and the centering positioning strips are arranged in a staggered manner.

[0015] The technical solution adopted by the utility model can independently take out and discharge the battery core. Compared with the traditional battery core gripper that takes and places the battery core at the same time, the patented gripping fixture of the technical solution can independently take out and discharge the battery core. Each clamping unit can be independently lifted and controlled by a lifting unit.
