Description

TECHNICAL FIELD

[0001] The utility model relates to a conveying device, especially a conveying device for battery piece. BACKGROUND

[0002] In the production process of battery piece, the battery piece needs to be put into the carrier plate to be conveyed into the vacuum chamber of PVD for coating. In this process, the carrier frame of the carrier plate carrying the battery piece will partially block the battery piece from being coated, thereby forming a mask.

[0003] The mask cannot be avoided in the production process of battery piece, and the area of the mask can only be reduced by reducing the area of contact between the carrier frame and the battery piece. However, this will increase the difficulty of automatic feeding of the battery piece onto the carrier plate. The smaller the carrier frame of the carrier plate, the more difficult it is to accurately place the battery piece. When the battery piece is not accurately placed in the carrier frame, the surface of the battery piece will be blocked by the carrier plate, resulting in a large area of uncoated film.

[0004] In the prior art, the current battery piece is fed onto the carrier plate by using machine vision recognition to align the positions of the carrier frame and the battery piece, and then the battery piece is placed into the carrier frame by adjusting the position of the battery piece by the automatic mechanical gripper. After the machine vision recognizes the alignment of the battery piece, the device itself does not have a method to automatically correct the position of the battery piece, and still needs to be manually corrected. Manual correction is prone to omissions or defects. In addition, the machine vision recognition of the alignment of the battery piece also has the problem of missed detection, which causes the battery piece to fall in the cavity or abnormal coating after entering the cavity.

[0023] Figure 4 The three-dimensional structure schematic diagram of the conveying wheel of the carrier plate device in an embodiment is shown.

[0024] Figure 5 The schematic diagram of the carrier plate body of the carrier plate device in an embodiment is shown in the perspective view. DETAILED DESCRIPTION

[0025] The carrier plate device for improving the film plating deviation of the battery piece will be further explained and described in combination with the drawings and specific embodiments in the specification, but the explanation and description do not constitute improper limitation on the technical scheme of the carrier plate device.

[0026] In the production process of the battery piece, the battery piece needs to be put into the carrier plate for conveying into the vacuum chamber of the PVD for film plating. In this process, the bearing frame of the carrier plate bearing the battery piece will block part of the battery piece from being plated, thereby forming a mask.

[0027] At present, the battery piece is automatically loaded onto the carrier plate by using machine vision recognition to align the positions of the carrier plate frame and the battery piece, and then the battery piece is put into the bearing frame by adjusting the position of the battery piece through the automatic mechanical gripper. After the machine vision recognizes the alignment of the battery piece, the device itself does not have an automatic method to correct the position of the battery piece, and still needs to correct the position of the battery piece manually. Manual correction is easy to miss or cause defects. In addition, the machine vision recognition of the alignment of the battery piece also has the problem of missed detection, which causes the battery piece to fall in the cavity or abnormal film plating after entering the cavity.

[0028] Based on this, the carrier plate device for improving the film plating deviation of the battery piece is provided in an embodiment, so as to directly reduce the probability of film plating deviation by simple structure and design.

[0029] Figure 1 The front structure schematic diagram of the carrier plate device in an embodiment is shown.

[0030] As shown in Figure 1 some embodiments, the carrier plate device for improving the film plating deviation of the battery piece includes a carrier plate body 1 and a conveying wheel 2. The conveying wheel 2 is arranged below the carrier plate body 1, and the rotation of the conveying wheel around its own axis in the R direction can make the carrier plate body 1 travel in the conveying direction P of the battery piece.

[0031] The outer circumferential surface of the conveying wheel 2 is provided with a protruding part 21 protruding radially outward, which makes the carrier plate body 1 alternately contact and move with the protruding part 21 and the non-protruding part on the outer circumferential surface of the conveying wheel 2 when the conveying wheel 2 rotates around its own axis, in which case, the carrier plate body generates a displacement in the height direction, which causes the carrier plate body to vibrate slightly, especially when the carrier plate body is made of metal material and generates elastic deformation due to inertia, which is more prone to vibration.

[0032] As shown in Figure 2 , when the battery piece Q is offset on the carrier plate body, i.e. is placed obliquely in the bearing frame 12 of the carrier plate body without falling completely into the bearing frame. The vibration of the carrier plate body 1 makes the battery piece Q slide into the bearing frame 12 in the height direction, so as to realize the accurate alignment of the battery piece Q and the bearing frame 12 of the carrier plate body, as shown in Figure 3 .

[0033] In some more specific embodiments, as shown in Figure 1 , a plurality of conveying wheels 2 are arranged below the carrier plate body 1 along the conveying direction P of the battery piece. In order to ensure the stability of the carrier plate body conveying, generally at least two conveying wheels are arranged.

[0034] Figure 4 The three-dimensional structure schematic diagram of the conveying wheel in one embodiment of the carrier plate device.

[0035] In some more specific embodiments, as shown in Figure 4 , the outer circumferential surface of the conveying wheel 2 is provided with a plurality of protruding parts 21 arranged along the circumferential direction thereof, for example, four as shown in Figure 4 .

[0036] Of course, in other alternative embodiments, only one protruding part can be arranged.

[0037] In some more specific embodiments, as shown in Figure 4 , the plurality of protruding parts 21 are uniformly arranged on the outer circumferential surface of the conveying wheel 2.

[0038] Of course, in other alternative embodiments, the plurality of protruding parts 21 can also be arranged non-uniformly on the outer circumferential surface of the conveying wheel 2.

[0039] In some more specific embodiments, as shown in Figure 4 , the protruding parts 21 are continuously arranged in the axial direction of the conveying wheel 2.

[0040] Of course, in other alternative embodiments, the protruding parts 21 can also be discontinuously arranged in the axial direction of the conveying wheel 2.

[0041] In some more specific embodiments, as shown in Figure 4 The extension length of the protrusion is the same as the axial length of the conveying wheel.

[0042] Of course, in other alternative embodiments, the extension length of the protrusion 21 can also be shorter than the axial length of the conveying wheel 2.

[0043] In some more specific embodiments, as shown in Figure 4 The upper surface (i.e. top surface) of the protrusion 21 is arc-shaped.

[0044] In some more specific embodiments, as shown in Figure 5 The carrier plate body includes an outer frame 11 and a plurality of bearing frames 12 arranged inside the outer frame 11, the bearing frames 12 being used for accommodating the battery pieces, and the conveying wheel is in contact with the outer frame 11.

[0045] As shown in Figure 2 And Figure 3 In some preferred embodiments, the side wall 121 of the bearing frame 12 is arranged obliquely. Since the bearing frame has an oblique inward slope, when the carrier plate body vibrates, the battery pieces are more likely to slide slowly into the bearing frame along the bearing frame slope, so as to realize accurate alignment of the battery pieces with the bearing frame of the carrier plate body.

[0046] In addition, in some other embodiments, the carrier plate device can also include a vibration motor, such as an eccentric vibration motor, which is connected with the carrier plate body, so as to further ensure the vibration of the carrier plate body.

[0047] Therefore, the carrier plate device can make the battery pieces on the carrier plate body slowly fall to the bottom of the bearing frame under vibration, so as to realize offset correction between the battery pieces and the bearing frame, and then realize improvement of the plating offset of the battery pieces, and improve the production yield and reduce the abnormality of the battery pieces falling into the PVD machine cavity.

[0048] The carrier plate device has simple structure and low cost, and can directly reduce the probability of plating offset, without manual processing of the abnormality of the plating offset of the battery pieces.
