DETAILED DESCRIPTION

[0033] ​In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0035] As shown in Figure 1 , Figure 4 and Figure 5 , the pole piece pre-positioning device 100 of some embodiments of the present application includes a pre-positioning mechanism 110 and a deviation rectification mechanism 120. The pre-positioning mechanism 110 includes a base 111 and a first deviation rectification assembly 112 and a second deviation rectification assembly 113 mounted on the base 111, which are configured to sequentially carry the pole piece to a deviation rectification station 150; the deviation rectification mechanism 120 is used to drive the base 111 to move; the deviation rectification mechanism 120 is used to adjust the position of the base 111, so as to rectify the pole piece on the first deviation rectification assembly 112 or the second deviation rectification assembly 113 at the deviation rectification station 150.

[0036] When the first deviation rectification assembly 112 carries the pole piece to the deviation rectification station 150, the deviation rectification mechanism 120 is used to adjust the position of the base 111 to rectify the pole piece carried by the first deviation rectification assembly 112; when the second deviation rectification assembly 113 carries the pole piece to the deviation rectification station 150, the deviation rectification mechanism 120 is used to adjust the position of the base 111 to rectify the pole piece carried by the second deviation rectification assembly 113.

[0037] The deviation rectification station 150 is also provided with a visual recognition mechanism, which is a CCD camera or other forms of image recognition device or thermal imaging device. The visual recognition mechanism is used to detect whether the pole piece at the deviation rectification station 150 is qualified and whether it is adjusted to a preset posture, which serves as a reference for the pole piece taking manipulator to take the material and then feed it to the pole piece stacking device or perform waste disposal.

[0038] The base 111 is arranged at the execution end of the deviation rectification mechanism 120, and under the driving of the deviation rectification mechanism 120, the base 111 can be finely adjusted in position, and cooperate with the detection feedback result of the visual recognition mechanism to rectify the pole piece until the pole piece is adjusted to a preset posture.

[0039] In some embodiments of the present application, the first deviation rectifying assembly 112 is arranged at the deviation rectifying station 150. After the pole piece of the first deviation rectifying assembly 112 is completed with the deviation rectifying treatment and is discharged or discarded, the second deviation rectifying assembly 113 carries the pole piece to the deviation rectifying station 150 to perform the deviation rectifying treatment at the deviation rectifying station 150. In other embodiments, the pre-positioning mechanism 110 can be switched between the deviation rectifying position and the feeding position. The pre-positioning mechanism 110 simultaneously receives two pole pieces at the feeding position in one beat. The base 111 moves as a whole. The first deviation rectifying assembly 112 and the second deviation rectifying assembly 113 carry the pole pieces to the deviation rectifying station 150 in turn to perform the deviation rectifying treatment.

[0040] The pole piece pre-positioning device 100 of the embodiments of the present application is used to perform the deviation rectifying treatment of the pole piece. The feeding robot can simultaneously feed two pole pieces in one beat. The first deviation rectifying assembly 112 and the second deviation rectifying assembly 113 receive one pole piece respectively. The first deviation rectifying assembly 112 and the second deviation rectifying assembly 113 carry the pole pieces to the deviation rectifying station 150 in turn to perform the deviation rectifying treatment. Since the reciprocating frequency of the feeding robot is reduced, the beat of the deviation rectifying station 150 can be faster, thereby improving the pole piece deviation rectifying efficiency and the pole piece stacking efficiency.

[0041] In some embodiments of the present application, as shown in Figure 2 and Figure 3 , the first deviation rectifying assembly 112 includes a lifting driving assembly 1121 and a first deviation rectifying table 1122. The lifting driving assembly 1121 is installed on the base 111 and is used to drive the first deviation rectifying table 1122 to move along the vertical direction Z. As shown in Figure 6 and Figure 7 , the second deviation rectifying assembly 113 includes a horizontal movement driving assembly 1131 and a second deviation rectifying table 1132. The horizontal movement driving assembly 1131 is installed on the base 111 and is used to drive the second deviation rectifying table 1132 to move along the first direction X. The first deviation rectifying table 1122 is arranged at the deviation rectifying station 150. When the horizontal movement driving assembly 1131 drives the second deviation rectifying table 1132 to carry the pole piece to move to the deviation rectifying station 150 along the first direction X, the lifting driving assembly 1121 is configured to drive the first deviation rectifying table 1122 to descend to avoid the second deviation rectifying table 1132.

[0042] After the first deviation rectifying table 1122 carries the pole piece to complete the deviation rectifying treatment at the deviation rectifying station 150, the first deviation rectifying table 1122 descends along the vertical direction Z under the driving of the lifting driving assembly 1121. The second deviation rectifying table 1132 horizontally moves to the deviation rectifying station 150 under the driving of the horizontal movement driving assembly 1131 until it reaches the deviation rectifying station 150. The first deviation rectifying table 1122 is located at the lower side of the second deviation rectifying table 1132. The pole piece carried by the second deviation rectifying table 1132 is subjected to the deviation rectifying treatment.

[0043] Through the arrangement, the position switching of the first deviation rectifying table 1122 and the second deviation rectifying table 1132 can be realized, and the pole piece is sequentially carried to the deviation rectifying station 150 for deviation rectifying treatment, thereby improving the deviation rectifying efficiency.

[0044] In other embodiments, the position switching of the first deviation rectifying table 1122 and the second deviation rectifying table 1132 can also be realized through other moving manners. For example, the first deviation rectifying table 1122 and the second deviation rectifying table 1132 can be located on the same turntable, and the turntable is rotated to drive the first deviation rectifying table 1122 and the second deviation rectifying table 1132 to sequentially reach the deviation rectifying station 150.

The motor 1123 is installed on the base 111 and is used to drive the transmission shaft 1124 to rotate; the cam 1125 is eccentrically installed on the transmission shaft 1124, and the cam 1125 abuts against the lower surface of the first deviation rectifying table 1122; the motor 1123 is used to drive the transmission shaft 1124 to rotate, so as to drive the first deviation rectifying table 1122 to move along the vertical direction Z through the cam 1125.

[0046] The first deviation rectifying table 1122 is installed on the top side of the lifting support 1127, the lifting support 1127 is slidingly installed on the base 111 through the first guide rail assembly 1126 in the vertical direction Z, and the axial direction of the transmission shaft 1124 extends along the first direction X.

[0047] Through the arrangement, the first deviation rectifying table 1122 can be simply and reliably driven to ascend and descend along the vertical direction Z.

[0048] In other embodiments, the first deviation rectifying table 1122 can also be driven to ascend and descend along the vertical direction Z through other linear driving mechanisms.

It can be understood that when the gear 1134 rotates, the first rack 1135 and the second rack 1136 respectively move in opposite directions along the first direction X.

[0055] The pole piece carried by the first deviation rectifying station 1122 or the second deviation rectifying station 1132 is subjected to visual inspection again after the deviation rectifying process is completed at the deviation rectifying station 150, to determine whether it is a qualified product. For a qualified pole piece, the blanking is performed into the lamination operation; for an unqualified pole piece, the unqualified pole piece is subjected to unqualified pole piece removal treatment through the unqualified pole piece removal mechanism 130.

[0056] Through the setting form, the unqualified pole piece can be removed, and the unqualified pole piece removal mechanism 130 is moved to the deviation rectifying station 150 to receive the unqualified pole piece, thereby improving the unqualified pole piece removal efficiency.

[0080] Due to the characteristics of the sheet pre-positioning device 100 of the embodiments of the present application, the lamination device 200 of the embodiments of the present application has a higher lamination efficiency.

[0081] As shown in the drawings, Figure 10 In some embodiments of the present application, the lamination device 210 is installed at the execution end of the transverse deviation rectifying driving assembly 121, which is used to drive the lamination device 210 to move.

[0082] The execution end of the transverse deviation rectifying driving assembly 121 is installed with another first sliding plate 124, and the lamination device 210 is installed on the other first sliding plate 124.

[0083] Through this kind of setting form, the distance between the pre-positioning mechanism 110 and the lamination device 210 can be adjusted according to the production line requirements, and the structure of the sheet pre-positioning device 100 is simplified.

[0084] In other embodiments, the lamination device 210 and the sheet pre-positioning device 100 can also be independently arranged.

[0085] As shown in the drawings, Figure 11 Based on the aforementioned embodiment that the sheet pre-positioning device 100 comprises the positive electrode pre-positioning mechanism 141 and the negative electrode pre-positioning mechanism 142, the sheet taking manipulator 220 is provided with two, corresponding to the positive electrode pre-positioning mechanism 141 and the negative electrode pre-positioning mechanism 142 respectively, and the positive electrode pre-positioning mechanism 141, the negative electrode pre-positioning mechanism 142 and the lamination device 210 are all installed on the same transverse deviation rectifying driving assembly 121. The two sheet taking manipulators 220 grab the positive electrode sheet and the negative electrode sheet from the positive electrode pre-positioning mechanism 141 and the negative electrode pre-positioning mechanism 142 respectively, and feed them to the lamination device 210 alternately to perform the lamination work.

[0086] The working principle of the sheet pre-positioning device 100 and the lamination device 200 of the embodiments of the present application is as follows:

[0087] The feeding manipulator feeds two electrode sheets to the first deviation rectifying table 1122 and the second deviation rectifying table 1132 respectively in one beat;

[0088] The first deviation rectification table 1122 is located at the deviation rectification station 150. The pole piece carried by the first deviation rectification table 1122 is subjected to deviation rectification treatment at the deviation rectification station 150. After deviation rectification, visual inspection is performed. The qualified pole piece is moved to the pole piece stacking device 210 by the pole piece taking manipulator 220 for stacking operation. The unqualified pole piece is grabbed by the pole piece taking manipulator 220. The waste sorting table 132 is moved to the upper side of the first deviation rectification table 1122. The pole piece taking manipulator 220 places the unqualified pole piece on the waste sorting table 132. The waste sorting driving assembly 131 drives the waste sorting table 132 to move to the waste sorting station for waste sorting treatment.

[0089] The transverse driving assembly 1131 drives the second deviation rectification table 1132 to move to the deviation rectification station 150 along the first direction X. The lifting driving assembly 1121 drives the first deviation rectification table 1122 to descend to the lower side of the second deviation rectification table 1132 along the vertical direction Z to avoid the second deviation rectification table 1132. The pole piece carried by the second deviation rectification table 1132 is subjected to deviation rectification treatment at the deviation rectification station 150. According to the visual inspection result after deviation rectification, stacking operation or waste sorting treatment is performed.

[0090] Under the driving of the lifting driving assembly 1121 and the transverse driving assembly 1131, the first deviation rectification table 1122 and the second deviation rectification table 1132 are reset respectively. The feeding manipulator feeds two pole pieces again in the next cycle. The above deviation rectification process is repeated.

[0091] The positive electrode pre-positioning mechanism 141 and the negative electrode pre-positioning mechanism 142 respectively perform deviation rectification treatment on the positive electrode pole piece and the negative electrode pole piece. The respective pole piece taking manipulators 220 alternately provide the qualified positive electrode pole piece and the negative electrode pole piece to the pole piece stacking device 210 and perform waste sorting treatment on the unqualified pole piece.

[0092] The pole piece pre-positioning device 100 and the pole piece stacking equipment 200 can receive two pole pieces in each cycle and perform deviation rectification treatment one by one, thereby improving the pole piece deviation rectification efficiency and the pole piece stacking efficiency.

[0093] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0094] The above only describes the preferred embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
