The movable limiting part is provided with a limiting surface 403 which is parallel to the blocking limiting part, and the movable limiting part is driven to move close to the blocking limiting part so as to form a conveying channel matched with the battery cell 2 between the blocking limiting part and the limiting surface 403 above the conveying unit.

Based on the above general description, an exemplary structure of the soft-package cell loading device described in this embodiment is shown in fig. 1 and fig. 2. The supporting unit is used as a mounting carrier, preferably adopts the substrate 1 which is arranged in a horizontal extending way, has a simple structure and has a better bearing effect. The base plate 1 may be fixed to a frame when in use. Of course, the supporting unit in this embodiment may also adopt other bearing structures arranged on the rack besides the base plate 1.

The conveying unit in the present embodiment includes a conveyor belt 3 that carries the battery cells 2, and a plurality of rotatable rollers 103 that are drivable to roll and support the conveyor belt 3. As shown in fig. 1, an installation space is provided on the substrate 1, and three rotating rollers 103 are arranged at intervals in the longitudinal direction of the installation space. Preferably, the installation space may be a through hole formed in the substrate 1, which has a simple structure and is convenient for forming on the substrate 1.

The three rotating rollers 103 in this embodiment are disposed in the installation space of the base plate 1 in parallel and pivotally, and the conveyor belt 3 is wound around the three rotating rollers 103. Here, the rotation roller 103 is pivotally provided on the substrate 1 means that the rotation roller 103 can rotate relative to the substrate 1 with its axis as a center line. Of course, the number of the rotating rollers 103 in the present embodiment can be adaptively increased or decreased according to specific use requirements. In order to improve the use effect of the rotating roller 103, the rotating roller 103 in this embodiment may specifically adopt a rubber roller in the prior art.

In order to drive the conveyer belt 3 to convey the battery core 2, in this embodiment, a servo motor 6 is further installed on the rack, and the rotating roller 103 is drivingly coupled to a power output end of the servo motor 6. Specifically, as shown in fig. 1, the servomotor 6 is located below the end of one of the rotating rollers 103 located outermost. A first transmission wheel 601 is connected to a power output end of the servo motor 6 via a coupling, a second transmission wheel 603 is provided at an end of the rotating roller 103 corresponding to the first transmission wheel 601, and a transmission belt 602 is wound around the first transmission wheel 601 and the second transmission wheel 603.

Under the driving of the servo motor 6, the first driving wheel 601 can transmit the rotational driving force to the second driving wheel 603 through the driving belt 602, and drive the rotating roller 103 to drive the conveying belt 3 and the other rotating rollers 103 to rotate, so as to transmit the electric core 2. Of course, other structures besides the first driving wheel 601, the second driving wheel 603 and the driving belt 602 can be adopted between the servo motor 6 and the rotating roller 103 as long as the use requirement of the driving is met.

The battery cell 2 in this embodiment is usually placed at an input end of the conveyor belt 3, and the conveyor belt 3 is driven by the servo motor 6 to convey the battery cell 2 to an output end of the conveyor belt 3. It is to be noted that the preset position in the present embodiment is set corresponding to the acquisition position of the robot. So, when electric core 2 carried to predetermineeing the position, the manipulator just can be accurate carry electric core 2 who targets in place to acquire. Preferably, the predetermined position is in particular located at the output end of the conveyor belt 3.

The manipulator in this embodiment can adopt ripe structure among the prior art, and this manipulator absorbs the upper surface of electric core 2 through the sucking disc to shift electric core 2 on the conveyer belt 3. Of course, the manipulator may also adopt other structures that are convenient for acquiring the battery cell 2 besides using the suction cup.

The blocking and limiting portion in this embodiment is provided corresponding to one side of the width direction of the conveyor belt 3. As shown in fig. 1 and fig. 2, the blocking limiting part is a blocking plate 101 vertically connected to the substrate 1, and the blocking plate 101 extends along the conveying direction of the battery cells 2 and has the above-mentioned extending length. Here, the barrier plate 101 may be integrally formed with the base plate 1, or separately formed and fixed to the base plate 1 by a welding or connecting structure.

It should be noted that, in the present embodiment, the blocking surface 102 disposed toward the conveying belt 3 is used for blocking the blocking plate 101. Therefore, the blocking limiting part may have other structures besides the blocking plate 101, as long as it has the blocking surface 102, and the blocking surface 102 is parallel to the conveying direction of the conveying belt 3 and perpendicular to the upper surface of the conveying belt 3.

The movable stopper in this embodiment is provided on the other side of the conveyor belt 3 with respect to the stopper plate 101. As shown in fig. 1 and fig. 2, the movable limiting part is a limiting plate 4, and the side surface of the limiting plate 4 facing the conveyor belt 3 is the limiting surface 403. Here, the limiting plate 4 is simple in structure and convenient to structure-form. Of course, the movable limiting portion in this embodiment may have other structures besides the limiting plate 4, as long as it has the limiting surface 403.

Preferably, the limiting plate 4 is disposed to move along a direction orthogonal to the conveying direction of the conveyor belt 3, and pushes the battery cell 2 to approach the blocking plate 101 during the movement, so that the battery cell 2 defines a conveying channel matched with the battery cell 2 on the limiting surface 403, the blocking surface 102, and the upper surface of the conveyor belt 3, thereby improving the consistency of the conveying position of the battery cell 2 on the conveyor belt 3. It should be noted that, the fact that the conveying channel is matched with the battery cell 2 means that the width of the conveying channel is slightly larger than the width of the battery cell 2, so as to ensure that the battery cell 2 can be conveyed smoothly.

In this embodiment, electric core 2 can adopt artificial mode to place the input at conveyer belt 3, because human error, leads to each electric core 2 position on conveyer belt 3 is wide easily inconsistent with the position of predetermineeing. And the limiting plate 4 moves towards the blocking plate 101, so that the side part of the battery cell 2 can be abutted in the moving process, the battery cell 2 is pushed, the side part of the battery cell 2 can be parallel to the limiting surface 403, and the arrangement directions of the battery cells 2 are consistent. Simultaneously, under the top of limiting plate 4 pushes away, electric core 2 can remove to the ascending target position of 3 width directions of conveyer belt to carry to predetermineeing the position via electric core 2 transfer passage.

During specific implementation, based on the preset position, the target displacement of the limiting plate 4 can be obtained by the widths of the conveyor belt 3 and the battery cell 2, and the displacement of the limiting plate 4 required to be moved is also obtained. When the displacement of limiting plate 4 satisfied the displacement of target volume, electric core 2 was located the ascending target position of 3 width directions of conveyer belt to improve the location and the transport effect to electric core 2, and then improve the uniformity of material loading.

In addition, in order to improve the conveying effect of the battery cell 2 in the battery cell 2 conveying channel, gaps are provided between two sides of the battery cell 2 at the target position and the blocking surface 102 and the limiting surface 403. When the battery cell 2 is placed at the input end of the conveyor belt 3, it is necessary to ensure that a space is left between the battery cell 2 and the blocking plate 101. The distance is reduced due to the pushing of the limiting plate 4 to the battery cell 2, but the battery cell 2 is not contacted with the blocking surface 102 under the pushing of the limiting plate 4. And the clearance between barrier plate 101 and electric core 2, accessible cylinder 5 removes behind the limiting plate 4 reaches the target displacement volume, and the return certain distance can. Preferably, gaps of 0.8-1.2 mm are formed between the two sides of the battery cell 2 and the stop plate 101 and the limit plate 4. For example, both gaps are 1mm here.

In order to ensure the pushing effect of the limiting plate 4 on the electric core 2, in this embodiment, the conductive handle of the electric core 2 placed at the input end should not be disposed toward the limiting plate 4. Thus, the limiting plate 4 can be ensured not to damage the conductive handle when contacting with the battery cell 2. In addition, the limiting plate 4 should slowly push the electric core 2 to ensure that the electric core 2 stably moves towards the direction of the blocking plate 101 after being pushed, so as to improve the consistency of the electric core 2 after positioning.

In this embodiment, in order to improve the use effect of the limiting plate 4 in this embodiment, a protective layer 401 is further disposed on the limiting surface 403 to protect the surface of the soft package battery core 2. In this case, the side of the protective layer 401 facing the conveyor belt 3 forms a stop surface 403. In one embodiment, the protective layer 401 may be made of rubber. Of course, the protective layer 401 can also be made of other materials with protective function, such as sponge.

In this embodiment, a linear power output unit is fixedly disposed on the substrate 1, and a power output end of the linear power output unit is coupled to the limiting plate 4 to apply a driving force perpendicular to the blocking plate 101 to the limiting plate 4.

The two cylinders 5 in this embodiment are used synchronously, which is beneficial to ensuring that the spacing surface 403 keeps the parallel relationship with the blocking surface 102 during movement, thereby improving the positioning effect of the battery cell 2 during transportation.

It should be noted that there may be only one cylinder 5 in the present embodiment. Specifically, guide grooves are provided in the base plate 1 corresponding to both ends of the stopper plate 4, and both ends of the stopper plate 4 are inserted into the guide grooves. The middle part of the cylinder 5 corresponding to the limit plate 4 is fixed on the base plate 1. At this time, under the driving of the cylinder 5, the limit plate 4 is guided by the guide groove, so that the parallel relationship between the limit surface 403 and the blocking surface 102 can be ensured, and a good positioning effect is achieved.

In order to improve the using effect of the soft-package battery cell feeding device, the servo motor 6 in the embodiment is controlled by the control unit. In addition, a sensing unit is arranged at the preset position, and the sensing unit is controlled by the control unit and used for sensing the battery cell 2. In this embodiment, the control unit is connected to the servo motor 6 and the sensing unit, respectively. When sensing unit carried to predetermineeing the position at electric core 2 and sent detecting signal to controller 7, controller 7 took place stop signal to servo motor 6 after receiving this detecting signal to make conveyer belt 3 stop carrying, and the manipulator of can being convenient for acquires electric core 2.

The control unit in this embodiment may be a controller 7 in the prior art, such as a PLC controller 7, and the controller 7 is fixed on the frame adjacent to the servo motor 6. Preferably, the sensing unit in this embodiment can adopt the optical fiber sensor 402 in the prior art, and the product is mature and the use effect is good. Of course, instead of using the fiber optic sensor 402, the sensing unit may also use other position sensors that are known in the art to facilitate position sensing.

The optical fiber sensor 402 in this embodiment is fixed to the stopper plate 4. As shown in fig. 1 and 2, the fiber sensor 402 is provided on the upper surface of the position restricting plate 4 corresponding to the output end of the conveyor belt 3. In order to ensure that the optical fiber sensor 402 can accurately detect the cell 2, in this embodiment, the upper surface of the limiting plate 4 is lower than the upper surface of the cell 2, and the cell 2 is located on a transmission path of a detection signal sent by the optical fiber sensor 402. For example, the distance between the upper surface of the limit plate 4 and the upper surface of the cell 2 is greater than half the thickness of the cell 2.

In this embodiment, the optical fiber inductor 402 is disposed on the limiting plate 4, so that a transmission path of the detection signal sent by the optical fiber inductor 402 remains unchanged, and a detection effect of the optical fiber inductor 402 on the electric core 2 can be ensured. It is understood that the optical fiber sensor 402 in the present embodiment may be disposed on the blocking plate 101 in addition to the position limiting plate 4. In detail, a mounting hole is provided on the blocking plate 101 corresponding to the output end of the conveyor belt 3, and the optical fiber sensor 402 is specifically mounted in the mounting hole. At this time, the battery cell 2 is also located in the transmission path of the detection signal sent by the optical fiber sensor 402.

At this time, the manipulator acquires the battery cell 2 moved in place. And when optical fiber inductor 402 detects that electric core 2 is shifted, send a signal to controller 7 again, controller 7 sends a signal to cylinder 5 after receiving the signal, and cylinder 5 drives limiting plate 4 and resets to initial position.
