[0047] Example 1

[0048] like Figures 1-6 As shown, this embodiment provides an efficient plate-taking device for a sheet wrapping machine, comprising: a swing arm upright plate 2, a plate-taking assembly 3 slidingly arranged on the outer side of the swing arm upright plate 2, reciprocating along the side of the swing arm upright plate 2, grabbing and carrying the electrode plate to move back and forth; and a driving assembly 4, wherein the driving assembly 4 drives the plate-taking assembly 3 to move back and forth.

[0049] Preferably, the plate-taking assembly 3 moves in the horizontal and vertical directions driven by the driving assembly 4 to grab and move the electrode plates.

[0050] Preferably, Figure 1 As shown, the plate removal assembly 3 includes:

[0051] A first movable plate 31, which is laterally slidably disposed on one side of the swing arm vertical plate 2;

[0052] A second movable plate 32 is arranged to slide transversely on the swing arm vertical plate 2 and is located on one side of the first movable plate 31;

[0053] a third movable plate 33 , the third movable plate 33 being vertically slidably disposed on one side of the second movable plate 32 ;

[0054] A grabbing support plate 34 , the grabbing support plate 34 being connected to the third movable plate 33 and having a plurality of gripper assemblies 35 for grabbing the plates; and

[0055] A trajectory control component 36 , which controls the moving path of the grabbing support plate 34 , has one end connected to the third moving plate 33 .

[0056] It should be noted that the distance between the gripper assemblies 35 provided on the gripping support plate 34 is adapted to the size of the subsequent plate sorting station, and efficient plate removal can be achieved by providing multiple groups of gripper assemblies 35 .

[0057] Further, such as Figure 1 、 2 As shown, the trajectory control component 36 includes:

[0058] Track plate 361, the track plate 361 is provided below the swing arm vertical plate 2, and has a first track 3611 formed thereon;

[0059] a second track 362 , the second track 362 being provided below the first movable plate 31 ; and

[0060] The control rod 363 has one end connected to the third movable plate 33, and the other end passes through and rotates to connect the second track 362 and the first track 3611 in sequence; preferably, the control rod 363 is provided with two sets of rotating bearings which are respectively rotatably connected to the first track 3611 and the second track 362, and the rotating bearings are rollingly arranged in the first track 3611 and the second track 362.

[0061] Furthermore, Figure 2 、 3 As shown, the first track 3611 is provided with a horizontal section 36111 and an inclined section 36112 , and the second track 362 is inclined and forms an angle α with the inclined section 36112 .

[0062] Preferably, when the angle α is in the range of 0<α≤90°, when the plate taking assembly 3 runs to the inclined section 36112, the plate taking assembly 3 moves to the left, the grabbing support plate 34 moves downward, and the plate taking assembly 3 moves to the right, the grabbing support plate 34 moves upward.

[0063] The plate taking component moves downward to take the material, and the angle can be adjusted according to the position and speed of the plate taking.

[0064] Of course, this embodiment is for taking materials downward. If materials are taken upward, the inclined section 36112 can be inclined upward, and at the same time cooperate to achieve an acute angle α to achieve upward material taking.

[0065] As another embodiment, when the angle α is in the range of 90<α<180°, when the plate taking assembly 3 runs to the inclined section 36112, the plate taking assembly 3 moves to the left, the grabbing support plate 34 moves upward, and the plate taking assembly 3 moves to the right, the grabbing support plate 34 moves downward.

[0066] Preferably, the angle between the inclined section 36112 and the vertical direction is less than 30°, which is convenient for rapid vertical movement to pick up materials. Of course, the angle can be adaptively adjusted according to different picking speeds at the root. For example, when picking up materials slowly, the angle can be set to less than 90°, that is, the lateral movement distance is increased, so that the vertical movement is slow, thereby controlling the picking speed.

[0067] It should be noted that, under the synchronous action of the first track 3611 and the second track 362, the control rod 363 moves in the horizontal section 36111 to realize the lateral movement of the grabbing support plate 34. When the control rod 363 moves to the inclined section 36112, under the action of the second track 362, the control rod 363 reciprocates in the vertical direction, and drives the grabbing support plate 34 to reciprocate in the vertical direction to grab the electrode plate.

[0068] In this embodiment, Figure 1 As shown, the gripper assembly 35 includes:

[0069] Guide rods 351, multiple groups of guide rods 351 are provided on the grab support plate 34;

[0070] A mounting plate 352 , the mounting plate 352 being disposed below the plurality of guide rods 351 ; and

[0071] Suction cups 353 , a plurality of suction cups 353 for negative pressure suction plates are provided on the mounting plate 352 .

[0072] It should be noted that if Figure 4 As shown, when the shaft rotates to the rightmost end of the driving wheel 41, the driving rod 42 rotates to the horizontal position, and the grabbing support plate 34 moves to the rightmost end; here, the electrode plate on the suction cup 353 can be placed on the conveyor line below;

[0073] like Figure 5 As shown, when the shaft rotates to the upper left of the driving wheel 41, the control rod 363 moves to the intersection of the horizontal section 36111 and the inclined section 36112;

[0074] like Figure 6 As shown, the driving wheel 41 continues to rotate. When the shaft rotates to the leftmost end of the driving wheel 41, the control rod 363 moves downward under the action of the inclined section 36112 and the second track 362, and at the same time drives the grabbing support plate 34 to descend to the bottom and grab the electrode plate located below.

[0075] like Figure 1 As shown, the driving wheel 41 continues to rotate, driving the grabbing support plate 34 to move upward and move laterally along the horizontal section 36111; through the above method, the grabbing and lateral movement of the pole plate are completed, and the reciprocating movement of the grabbing support plate 34 is achieved through the circular motion of the driving wheel 41.

[0076] Example 2

[0077] like Figure 1 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0078] In this embodiment, the driving component 4 includes:

[0080] a driving rod 42 , one end of which is rotatably connected to the first movable plate 31 , and the other end of which is rotatably connected to the rotating shaft; and

[0081] A driving part, wherein the output end of the driving part drives the driving wheel 41 to rotate.

[0082] It should be noted that the cam transmission effect is achieved by the eccentrically arranged rotating shaft of the driving wheel 41. Under the drive of the driving part, the driving wheel 41 rotates, driving the driving rod 42 to move back and forth, thereby driving the plate removing assembly 3 to move back and forth.

[0083] It should be noted that the driving part may use a motor to directly drive the driving wheel 41 to rotate, or may use an indirect transmission connection method, such as chain drive, belt drive, etc.

[0084] Preferably, the length of the driving rod 42 is adjustable. It should be noted that by changing the length of the driving rod 42 , different plate removal distances can be adapted, thereby improving the versatility of the device.

[0086] like Figure 7As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0087] In this embodiment, by setting up a base plate 1, two groups of plate taking components 3 are set on both sides of the base plate 1, and at the same time, a group of driving components 4 are used to synchronously drive the two groups of plate taking components 3 to move synchronously, thereby realizing synchronous plate taking of multiple groups of plate taking components 3, thereby realizing efficient plate taking.

[0088] In addition, a set of drive components 4 can be selected to synchronously drive several sets of coaxially driven plate-removing components 3 to achieve synchronous movement, thereby improving the plate-removing efficiency. For example, four sets of plate-removing components 3 can be synchronously driven. The specific transmission connection method can be adaptively adjusted according to the method of synchronous movement of the two sets of plate-removing components 3 described above.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
