[0036] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Example

[0037] like Figures 1 to 10 As shown, a double-station high-efficiency slotting equipment includes a frame 1, a pole group clamp 2 is arranged on the frame 1, a support table 3 for carrying a plastic shell 10 is arranged below the pole group clamp 2, a top pressing component 4 for inserting the pole group positioned in the pole group clamp 2 into the plastic shell 10 is arranged above the pole group clamp 2, a first feeding mechanism 5 and a second feeding mechanism 6 are respectively arranged on both sides of the pole group clamp 2, a grabbing component 20 is arranged above the pole group clamp 2, and the grabbing component 20 is used to alternately grab the positive pole group 101 and the reverse pole group 102 respectively transported to the grabbing station by the first feeding mechanism 5 and the second feeding mechanism 6, and put the grabbed positive pole group 101 and reverse pole group 102 into each unit cell of the pole group clamp 2 in turn.

[0038] The first fixing mechanism includes a fixing seat fixedly arranged on the frame, and the pole group clamp 2, the top pressing assembly 4 and the support platform 3 are each arranged in two groups front and back, and the grabbing assembly 20 is arranged between the two groups of pole group clamps 2 front and back.

[0039] The feeding paths of the first feeding mechanism 5 and the second feeding mechanism 6 are provided with a sorting assembly 7 and a tab assembly 8 in sequence from front to back. The sorting assembly 7 is used to sort and align the pole groups, and the tab assembly 8 is used to synchronously sort the positive and negative tabs of the pole groups.

[0040] like Figure 7 As shown, the pole group clamp 2 includes a side clamp 21, a middle clamp 22, a damping member 23, a guide rod 24 and a driving member 25. The side clamps 21 are arranged at both ends and the side clamp 21 at one end is connected to the driving member 25. A plurality of middle clamps 22 are arranged in parallel and spaced apart between two side clamps 21. The guide rod 24 is passed between the middle clamp 22 and the side clamp 21. The damping member 23 is distributed between adjacent middle clamps 22 and side clamps 21.

[0041] Here, by respectively arranging a first feeding mechanism for conveying the positive electrode group and a second feeding mechanism for conveying the negative electrode group on both sides of the pole group clamp, and by arranging two clamps for grasping the positive electrode group and the negative electrode group on the same sliding seat, it is achieved that when one of the clamps moves to the left side to grasp the positive electrode group, the other clamp loads the grasped negative electrode group into the pole group clamp, and when the clamp grasping the negative electrode group moves to the right side, the clamp grasping the positive electrode group just drives the grasped positive electrode group to move above the pole group clamp. At this time, the pole group clamp has moved one cell driven by the driving member 25, and the clamp just loads the positive electrode group into an adjacent cell, which greatly improves the efficiency of the pole group entering the slot.

The leveling plate 93 is driven by the leveling cylinder 92 to level the cluster sides in the pole cluster fixture 2.

[0043] It is worth mentioning that, different from the existing pole group slotting equipment, the present invention improves the existing cluster clamp, sets notches on both sides, and cooperates with the left and right leveling plates 93 so that the pole group in the clamp is leveled before entering the slot, so as to avoid the pole plate being damaged by severe friction with the plastic shell wall when pressed into the slot due to the offset of the position of the pole plate in the pole group.

[0044] like Figure 3 and Figure 6 As shown, the first feeding mechanism 5 and the second feeding mechanism 6 both include a revolving chain 51 arranged on the frame 1, and a plurality of carriers 52 for carrying clusters are arranged in an array on the revolving chain 51. The revolving chain 51 includes a vertical section 511, and a film coating assembly 53 is arranged at the vertical section 511. When the carrier 52 passes through the vertical section 511 driven by the revolving chain 51, the pole group is transferred to the carrier 52 after the film coating assembly 53 completes the film coating. Here, the carrier 52 is composed of a bottom plate 521 and two U-shaped frame plates 522 symmetrically arranged on the bottom plate. The U-shaped structure is convenient for the gripper to clamp the pole group above. In addition, an outwardly inclined introduction block 523 is provided at the end of the U-shaped frame plate 522; the film coating assembly includes a film channel 531, a cutter 532 is provided on the front side of the film channel 531, and limit pressure blocks 533 are provided above and below the cutter 532. A transfer table 534 is provided on the rear side of the film channel 531. The cutter 532 and the limit pressure block 533 both work under the drive of the cylinder. After the upper and lower limit pressure blocks 533 limit the side pressure of the film, the cutter cuts it under the drive of the cylinder.

[0045] like Figure 2 and Figure 5 As shown, the grabbing assembly 20 includes a slide rail 61 arranged on the frame 1, a slide seat 62 slidably arranged on the slide rail 61, a lifting cylinder 63 arranged on the slide seat 62, a lifting rod a64 slidably arranged on the slide seat 62, and a left clamping hand 65 and a right clamping hand 66 arranged at the lower end of the lifting rod a64. The lifting rod a64 slides up and down driven by the lifting cylinder 63. A translation member 67 is also arranged on one side of the slide rail 61. The translation member 67 is connected to the slide seat 62 to drive it to slide left and right along the slide rail 61. The translation member is set as a rodless cylinder.

[0046] Furthermore, the pressing assembly 4 includes a pressing cylinder 41 fixed on the frame 1, a lifting rod b42 slidably arranged on the frame 1, and a plurality of slot pressing blocks 43 arranged at the end of the lifting rod b42. The lifting rod b42 slides up and down driven by the pressing cylinder 41, and the slot pressing blocks 43 correspond one by one to the space between two adjacent clamps on the pole group clamp 2.

[0047] It should be pointed out that a flattening assembly 103 is also provided between the two groups of pole group clamps 2, and the flattening assembly 103 is used to alternately flatten the pole groups in the front and rear pole group clamps 2 into which the pole groups are placed in the vertical direction.

[0048] There are two groups of pole group clamps, top pressing components 4 and support platform 3. The pole group clamps gradually move to the middle position when the positive pole groups and negative pole groups on the left and right sides are alternately loaded. When all the loading is completed, they just move to the bottom of the flattening component 103 between the two groups of pole group clamps. The flattening component 103 presses down and arranges the pole groups in the pole group clamps. After the arrangement is completed, it moves to the slot entry station on the support platform 3 for slot entry. When entering the slot, the pole group clamp on the other side simultaneously carries out the work of loading the pole group, which further improves the efficiency of the entire battery pole group slot entry, with a compact structure and smooth connection.

[0049] Furthermore, a lifting cylinder 31 is provided below the support platform 3 for driving the support platform 3 and the plastic shell 10 on the support platform 3 to rise, a conveying rack 32 is provided on one side of the support platform 3, and a pushing member 33 is provided on the other side for transferring the plastic shell on the support platform 3 that has completed the pole group into the groove to the conveying rack 32.

[0050] like Figure 8 As shown, the conveying frame 32 includes a plurality of conveying rollers. A rodless cylinder is disposed on one side of the conveying frame 32, and the rodless cylinder drives the plastic shell to move backward on the conveying rollers.

[0051] The arranging assembly 7 includes a group of arranging cylinders 71 respectively arranged on both sides of the rotating chain and an arranging plate 72 driven by the arranging cylinders 71; the pole ear assembly 8 includes a first cylinder 81 fixed on the frame 1, a second cylinder 82 raised and lowered by the first cylinder 81, a third cylinder 83 arranged above the second cylinder 82, and a fourth cylinder 84 raised and lowered by the third cylinder 83, the second cylinder 82 and the fourth cylinder 84 are both rodless cylinders, the two clamping blocks a85 of the second cylinder 82 are used to clamp and position the end of the pole group, and the two clamping blocks b86 of the fourth cylinder 84 are provided with two groups of clamps for clamping the positive pole ear and the negative pole ear respectively. The first clamp 87 and the second clamp 88 of the ear; the first clamp 87 and the second clamp 88 are both set as bolts, and the clamp block b86 is provided with a threaded hole matched with the bolt, and the spacing between the left and right clamps can be adjusted by rotation. When the pole group moves to the whole pole ear assembly 8, the first cylinder 81 drives the three cylinders above to move down synchronously, and then the second cylinder 82 drives the two clamps a85 to clamp and position the end of the pole group, and then the third cylinder 83 drives the fourth cylinder 84 to move down. After moving down to the specified position, the fourth cylinder 84 drives the two clamps b86 to move inward, and the first clamp 87 and the second clamp 88 squeeze the positive ear and the negative ear inward respectively;

[0052] The structure adopts a lifting method to solve the problem that the existing equipment can only squeeze and arrange the positive electrode ear, but not the negative electrode ear because the negative electrode ear is located on the inside, and realizes the synchronous squeezing and arrangement of the positive and negative electrode ears.

[0053] During operation, the assembled positive electrode group and the reverse electrode group are respectively coated by the left and right coating components 53 and then pushed to the first feeding mechanism 5 and the second feeding mechanism 6. The first feeding mechanism 5 and the second feeding mechanism 6 transport the positive electrode group and the reverse electrode group backwards respectively. During the transportation process, the sorting component 7 sorts the electrode groups opposite to them, and the ear shaping component 8 shapes the positive electrode ears and negative electrode ears of the incoming group synchronously, and then they are transferred to the grasping station, and one of the electrode group clamps 2 moves to the bottom of the grasping component 20, and the left gripper 205 on the grasping component 20 moves to the left side to clamp the reverse electrode group and then moves to the top of the electrode group clamp. At the same time, the right gripper 206 moves to the top of the positive electrode group on the right side, and the left gripper 20 5 While placing the negative electrode group into the cell of the electrode group fixture, the right clamp 206 clamps a group of positive electrode groups, and then the right clamp 206 moves to the top of the electrode group fixture, and at the same time the driving part drives the electrode group fixture 2 to move one cell to wait for the positive electrode group to be placed in the adjacent cell; when a single electrode group fixture is full of electrode groups, it just moves to the bottom of the flattening component 103, the flattening component 103 flattens the electrode group, and the flattening components 9 on both sides flatten the electrode group in the fixture, and then the electrode group fixture moves to the slot entry station for slot entry operation, and another electrode group fixture performs the electrode group loading operation, and the lifting cylinder 31 drives the support platform 3 connected to the plastic shell 10 to move up, and the pressing component 4 pushes the electrode group into the plastic shell through the slot entry pressure block 43.
