[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The embodiments of the present application provide a vacuum belt conveyor device and a vacuum belt detection device, which can solve the technical problems of high hardware cost and labor cost of replacing belts in related technologies.

[0031] See also Figure 1 and Figure 2As shown, a vacuum belt conveyor device provided in an embodiment of the present application comprises: a fixed plate 1; a vacuum chamber 2, wherein the vacuum chamber 2 comprises a vacuum fixed chamber 21 and a vacuum detection chamber 22, wherein the vacuum fixed chamber 21 is fixed to the fixed plate 1, and the vacuum detection chamber 22 is detachably mounted on the vacuum fixed chamber 21 or the fixed plate 1; and a vacuum belt 3, wherein the vacuum belt 3 is arranged on the surface of the vacuum fixed chamber 21 and the vacuum detection chamber 22. Among them, vacuum holes 5 are arranged on the vacuum belt 3, the vacuum fixed chamber 21 and the vacuum detection chamber 22, and the vacuum holes 5 on the vacuum belt 3 located above the vacuum fixed chamber 21 are connected to the interior of the vacuum fixed chamber 21, and the vacuum holes 5 on the vacuum belt 3 located above the vacuum detection chamber 22 are connected to the interior of the vacuum detection chamber 22, so that the electrode piece can be adsorbed and fixed through the vacuum holes 5.

[0032] In this embodiment, the fixing plate 1 is used to fix the vacuum chamber 2. The vacuum chamber 2 can be fixed to the fixing plate 1 in a detachable manner by bolts or screws. Of course, since the vacuum fixing chamber 21 does not need to be disassembled when changing the type, the vacuum fixing chamber 21 can also be fixed on the fixing plate 1 and cannot be disassembled. During the transmission of the electrode piece, when the electrode piece is transmitted to the position where the vacuum detection chamber 22 is located, the size of the electrode piece is detected. The vacuum detection chamber 22 can be detachably mounted to the vacuum fixing chamber 21, or it can be detachably mounted to the fixing plate 1, as long as the vacuum detection chamber 22 can be fixed. In addition, the vacuum detection chamber 22 and the vacuum fixing chamber 21 can be arranged side by side along the transmission direction of the electrode piece, or the vacuum detection chamber 22 can be fixed to the top of the vacuum fixing chamber 21 in the up and down direction. At this time, when the vacuum detection chamber 22 is disassembled, it is not necessary to disassemble and replace the entire vacuum chamber 2.

[0033] In this embodiment, the entire vacuum chamber 2 is split into a vacuum fixed chamber 21 and a vacuum detection chamber 22, and the vacuum detection chamber 22 involved in the detection part is split separately. When the pole piece size is changed, the vacuum detection chamber 22 can be directly replaced without disassembling and replacing the vacuum fixed chamber 21, that is, there is no need to replace the entire vacuum chamber 2, which greatly improves the changeover efficiency and reduces the cost, and solves the technical problems of high hardware cost and labor cost of replacing the belt in related technologies.

[0034] The vacuum belt conveyor device in this embodiment can be used not only to convey electrodes, but also to convey other products. When using the vacuum belt conveyor device to convey and inspect electrodes, a camera 6 arranged directly above the vacuum inspection cavity 22 can be used to perform size inspection on the electrode. The leather belt can drive the electrode to move to the bottom of the camera 6, which is the position of the vacuum inspection cavity 22.

[0035] Further, see Figure 2As shown, in one embodiment, the vacuum chamber 2 may include two vacuum fixed chambers 21, both of which are fixed to the fixed plate 1, and the two vacuum fixed chambers 21 are distributed on both sides of the vacuum detection chamber 22 along the transmission direction of the vacuum belt 3, and the vacuum detection chamber 22 is detachably mounted on the two vacuum fixed chambers 21. In this embodiment, the vacuum chamber 2 is divided into three sections, namely, two vacuum fixed chambers 21 and one vacuum detection chamber 22, wherein the structures of the two vacuum fixed chambers 21 may be the same or different, and the two vacuum fixed chambers 21 sandwich the vacuum detection chamber 22 in the middle, and in this embodiment, the two sides of the vacuum detection chamber 22 are preferably fixed to the two vacuum fixed chambers 21, for example, the vacuum detection chamber 22 is fixed to the vacuum fixed chamber 21 by bolts. Among them, the number of vacuum holes 5 distributed on the vacuum fixed chamber 21 can be more, so that even if a large-sized pole piece is replaced, the vacuum fixed chamber 21 can still absorb the pole piece intactly. In this embodiment, the vacuum detection chamber 22 is arranged between two vacuum fixing chambers 21 , which not only can stably fix the vacuum detection chamber 22 through the vacuum fixing chambers 21 on both sides, but also can complete the model change without disassembling the entire vacuum chamber 2 .

[0036] In other embodiments, the vacuum chamber 2 may be divided into more sections, not limited to the three sections in this embodiment. For example, three or four vacuum fixing chambers 21 may be provided, or two or three vacuum detection chambers 22 may be provided.

[0037] Further, see Figure 3 and Figure 4 As shown, in some embodiments, the vacuum detection chamber 22 may include: a fixed block 221, the fixed block 221 is detachably mounted on the vacuum fixed chamber 21 or the fixed plate 1; and a back plate 222 and a cover plate 223, the back plate 222 and the cover plate 223 are detachably mounted on the fixed block 221, and the back plate 222, the cover plate 223 and the fixed block 221 form a vacuum chamber, and the cover plate 223 is arranged with a plurality of vacuum holes 5, and the vacuum holes 5 are connected to the vacuum chamber. In this embodiment, the vacuum chamber is surrounded by a fixed block 221, a back plate 222 and a cover plate 223 that are detachably connected to each other. In this arrangement, when the size of the pole piece needs to be changed, only a larger cover plate 223 can be replaced or the cover plate 223 and the back plate 222 can be replaced at the same time, and the fixed block 221 does not need to be replaced, and fewer parts need to be replaced, which can further reduce costs. After replacement, the vacuum holes 5 distributed on the cover plate 223 match the size of the pole piece. The fixing block 221 can be detachably mounted on the vacuum fixing chamber 21 or the fixing plate 1 by means of bolts, and the back plate 222 and the cover plate 223 can also be detachably mounted on the fixing block 221 by means of bolts.

[0038] Based on the above technical solution, see Figure 4 As shown, in one embodiment, the fixing block 221 may include: a longitudinal fixing block 2211, which is detachably mounted on the vacuum fixing chamber 21 or the fixing plate 1, and the longitudinal fixing block 2211 is provided with a plurality of mounting positions, and the plurality of mounting positions are arranged at intervals along the width direction of the vacuum belt 3; a transverse fixing block 2212, which is detachably mounted on at least one of the mounting positions, and the back plate 222 is detachably mounted on the transverse fixing block 2212, and the cover plate 223 is detachably mounted on the longitudinal fixing block 2211. In this embodiment, two longitudinal fixing blocks 2211 and two transverse fixing blocks 2212 are preferably provided, the two longitudinal fixing blocks 2211 are spaced apart along the length direction (i.e., the transmission direction) of the vacuum belt 3, and the two transverse fixing blocks 2212 are spaced apart along the width direction of the vacuum belt 3, one of the longitudinal fixing blocks 2211 is fixed to the vacuum fixing cavity 21 on one side of the vacuum detection cavity 22 by bolts, and the other longitudinal fixing block 2211 is fixed to the vacuum fixing cavity 21 on the other side of the vacuum detection cavity 22 by bolts, and both ends of each transverse fixing block 2212 are fixed to the two longitudinal fixing blocks 2211 by bolts, and the longitudinal fixing block 2211 is provided with a plurality of installation positions corresponding to each transverse fixing block 2212, so that the distance between the two transverse fixing blocks 2212 can be adjusted by adjusting the installation position of the transverse fixing block 2212 on the longitudinal fixing block 2211. The back plate 222 is installed between the two horizontal fixing blocks 2212, and each side of the back plate 222 is fixed to the corresponding main fixing block 221 by bolts. When the distance between the two horizontal fixing blocks 2212 is adjusted, the back plate 222 of other sizes can be replaced; the cover plate 223 is also preferably fixed to the longitudinal fixing block 2211 by bolts. When a larger pole piece needs to be detected, the cover plate 223 that is wider along the width direction of the vacuum belt 3 can be directly replaced.

[0039] Of course, in other embodiments, the fixing block 221 may also be configured as an integrated unit; or both the longitudinal fixing block 2211 and the transverse fixing block 2212 may be configured as an integrated unit.

[0040] Further, see Figure 4 As shown, in one embodiment, the fixing block 221 is installed with a mounting bar 23, and the mounting bar 23 is installed with a backlight source 24. In this embodiment, the backlight source 24 is installed to the fixing block 221 using the mounting bar 23. When the position of the backlight source 24 needs to be replaced, the position of the mounting bar 23 on the fixing block 221 can be directly replaced, and there is no need to repeatedly disassemble the mounting point of the backlight source 24 on the mounting bar 23, so the backlight source 24 is not easily damaged.

[0041] See also Figure 4As shown, in some optional embodiments, the mounting bar 23 is provided with a waist-shaped hole 231, and the waist-shaped hole 231 extends along the width direction of the vacuum belt 3. The mounting bar 23 is installed on the fixing block 221 through the waist-shaped hole 231, so that the installation position of the mounting bar 23 on the fixing block 221 is adjustable. In this embodiment, the backlight source 24 is installed on the front and rear sides of the fixing block 221 through the mounting bar 23, and a mounting bar 23 is respectively provided on the left and right sides of each backlight source 24, that is, a total of 4 mounting bars 23 are provided. By providing the waist-shaped hole 231 on the mounting bar 23, the mounting bar 23 can be conveniently adjusted according to the size of the cover plate 223 and the back plate 222. When the size of the pole piece is changed, there is no need to replace the mounting bar 23 and the backlight source 24.

[0042] Of course, in other embodiments, the waist-shaped hole 231 may not be provided on the mounting strip 23 , and the waist-shaped hole 231 may be provided on the fixing block 221 , or a plurality of mounting points adapted to the mounting strip 23 may be provided on the mounting block to adjust the position of the backlight source 24 .

[0043] Further, see Figure 2 and Figure 3 As shown, in one embodiment, the fixing block 221 is further provided with a transparent glass plate 25, the transparent glass plate 25 is flush with the cover plate 223, and the transparent glass plate 25 is located on one side of the backlight source 24. In this embodiment, the transparent glass plate 25 is preferably a transparent organic glass plate, and the transparent glass plate 25 is located above the backlight source 24, and a transparent organic glass plate can be provided for each backlight source 24; the transparent organic glass plate in this embodiment is not only light-transmissive, but also can support the vacuum belt 3 on both sides of the cover plate 223.

[0044] Furthermore, in some embodiments, the transparent glass plate 25 is arranged parallel to and spaced from the backlight source 24. That is, in this embodiment, a gap may be left between the transparent glass and the backlight source 24, and the smaller the gap, the better. Leaving a gap here can ensure that the backlight source 24 is easy to install. In other embodiments, the transparent glass plate 25 and the backlight source 24 may also be attached to each other.

[0045] Further, see Figure 1 As shown, in one embodiment, the fixed plate 1 is further fixed with a belt drive assembly 4, and the belt drive assembly 4 drives the vacuum belt 3 to move. The belt drive assembly 4 in this embodiment can be located below the fixed plate 1, and the belt drive assembly 4 can drive the vacuum belt 3 to transport the pole piece on the vacuum chamber 2.

[0046] The embodiment of the present application also provides a vacuum belt detection device, which includes the above-mentioned vacuum belt conveyor and a detection device, and the detection device is arranged on one side of the vacuum belt conveyor. The vacuum belt conveyor in this embodiment can adopt the vacuum belt 3 transmission device provided in any of the above-mentioned embodiments, and realize the corresponding functions, which will not be repeated here. In addition, the detection device in this embodiment preferably adopts a camera 6, and the vacuum belt 3 can transport the pole piece to the position of the vacuum detection cavity 22, and the pole piece can be photographed by the camera 6 arranged above the vacuum detection cavity 22, so that the size of the pole piece can be detected.

[0047] When the vacuum belt detection equipment in this embodiment detects the pole piece and the pole piece size changes greatly, it is sufficient to directly replace the vacuum detection cavity 22 involved in the detection part without replacing the entire vacuum cavity 2. The belt can be quickly replaced, work efficiency is improved, and the hardware cost and labor cost of replacing the belt are reduced. The vacuum belt conveyor device also runs smoothly.
