Example 1

Fig. 1 shows a schematic configuration of the automatic strip feeding apparatus according to the present embodiment, fig. 2 shows an enlarged schematic configuration of the correction mechanism 300, and fig. 3 shows a side view of the automatic strip feeding apparatus. Referring to fig. 1, 2 and 3 in combination, the present embodiment provides an automatic strip conveying apparatus including a fixed base 100, and a strip conveying module provided on the fixed base 100. The belt conveying module comprises a conveying mechanism 200 and a correcting mechanism 300, wherein the conveying mechanism 200 is used for conveying a belt, and the correcting mechanism 300 is used for accurately adjusting the position between the belt and the next station so as to achieve the purposes of conveying the belt without deviation and improving the process efficiency and quality.

Specifically, the feeding mechanism 200 and the straightening mechanism 300 are provided on the fixed base 100 along the direction of the web feeding. The correction mechanism 300 includes a belt receiving platform 31, a first cylinder 32, a second cylinder 33, and a third cylinder 34. The tape connecting platform 31 is of a block structure which is horizontally arranged, and two upward protruding correction adjusting blocks 36 are symmetrically arranged on the tape connecting platform 31. In this embodiment, the correction adjusting block 36 is screwed to the taping platform 31, however, in some embodiments, the correction adjusting block 36 may be integrally formed with the taping platform 31, or may be slidably connected to the taping platform 31, which is not limited in detail herein. A correction position 37 for limiting the belt material is formed between the correction adjusting blocks 36, and the width of the correction position 37 is matched with the width of the belt material so as to facilitate the conveying of the belt material.

The first cylinder 32 is disposed right above the tape receiving platform 31, and a pressing block 35 is connected to the lower side of the first cylinder 32. The pressing block 35 is movable in the vertical direction by the driving of the first cylinder 32. In use, the first cylinder 32 drives the press block 35 to the correction position 37 to compress the strip against the correction position 37 of the taping platform 31 and to move the strip as the taping platform 31 moves. The second air cylinder 33 is also located above the tape splicing platform 31, and the output end of the second air cylinder 33 is connected with the tape splicing platform 31, so that the tape splicing platform 31 can move in the vertical direction under the driving of the second air cylinder 33. In use, the second cylinder 33 drives the taping platform 31 to move to the same horizontal as the next station. The third cylinder 34 is disposed on the belt receiving platform 31. When the novel strip splicing device is used, the third air cylinder 34 drives the strip splicing platform 31 to move in the horizontal direction, so that the strip splicing platform 31 moves and is connected with the next station, and the novel strip splicing device is convenient for exchanging new and old strips.

Fig. 4 shows a schematic structural diagram of the transverse wire rail, the vertical wire rail and the tape deck. Referring to fig. 1, 2 and 4 in combination, the orthotic mechanism 300 further includes a transverse rail 301, a mounting plate 302 mounted on the transverse rail 301, and a vertical rail 303 disposed on the mounting plate 302. Wherein, a cylinder seat 304 connected with the tape splicing platform 31 is arranged on the vertical linear rail 303. The second cylinder 33 is connected with a connecting seat 305 and is fixed on the mounting plate 302 through the connecting seat 305. The output end of the second cylinder 33 is connected to the taping platform 31 so as to drive the taping platform 31 to move along the extending direction of the vertical linear rail 303 through the cylinder block 304. The output end of the third air cylinder 34 is connected to the mounting plate 302, thereby driving the tape deck 31 connected to the mounting plate 302 to move along the extending direction of the transverse linear rail 301. That is, the taping platform 31 can be moved in the horizontal and vertical directions along the lateral and vertical rails 301 and 303 by the driving of the second and third cylinders 33 and 34.

It is added that, similarly to the second cylinder 33, the first cylinder 32 is connected to another connection base (not shown) and is fixed to the taping platform 31 by the other connection base. When the second and third cylinders 33, 34 drive the movement of the taping platform 31, the first cylinder 32 moves with the movement of the taping platform 31, thereby ensuring that the press block 35 can accurately clamp and stop the strip at the correction position 37.

The working process of the automatic belt conveying device is described in detail below by taking a tab belt as an example:

typically, the tab strip is manually wound onto the tape receiving platform 31 along the conveyor 200, and then moved to the next station and bonded to the old tab material strip under the conveyance of the automatic strip conveyor. In the automatic strip conveying device, the tab strip passes through the correction position 37 between the correction adjusting blocks 36, and meanwhile, the first air cylinder 32 drives the pressing block 35, so that the tab strip is clamped between the strip receiving platform 31 and the pressing block 35 and limited at the correction position 37, and the tab strip moves along with the movement of the strip receiving platform 31. After the tab strips are preliminarily fixed, the second air cylinder 33 drives the tape connecting platform 31 to move along the vertical line rail 303 until the tape connecting platform 31 and the next station on the right side are on the same horizontal line. Then, the third air cylinder 34 drives the tape connecting platform 31, so that the tape connecting platform 31 moves to the right in the horizontal direction along the transverse linear rail 301 through the mounting plate 302 and is connected with the next station, and the tab tape is conveniently conveyed to the next station for bonding new tab tape and old tab tape. The bonded tab strips are continuously and accurately conveyed to the next station under the driving of the conveying mechanism 200 and the limit of the correction position 37, so that the accuracy of the tab strip positions is ensured, the follow-up procedures are convenient to carry out, and the efficiency is improved. After the use of one tab strip is completed, the pressing block 35 is driven by the first air cylinder 32 to be far away from the tab strip and is restored to the initial position together with the tape receiving platform 31, and then the process is repeated to clamp and accurately convey the new tab strip, so that the conveying position of each tab strip corresponds to the next station.

It should be noted that, to further ensure accuracy of the belt material conveyance, the correction mechanism 300 in this embodiment is movably connected to the fixing base 100. Specifically, fig. 5 shows a schematic structural diagram of the driving mechanism 400 of the present embodiment. Referring to fig. 1 to 5 in combination, in the present embodiment, the driving mechanism 400 and the correcting mechanism 300 are fixed to the fixed base 100, but the positional relationship of the driving mechanism 400 and the correcting mechanism 300 is not particularly limited here. The driving mechanism 400 is connected to the slider mounting plate 11, and the correction mechanism 300 is integrally fixed to the slider mounting plate 11. The driving mechanism 400 includes a first motor 41 and a screw 42 connected to the first motor 41, and the slider mounting plate 11 is connected to the screw 42. The first motor 41 drives the screw rod 42 to rotate, and then drives the slider mounting plate 11 connected with the screw rod 42 to move in the vertical direction of the fixed base 100, so as to finally realize the up-and-down movement of the correction mechanism 300 relative to the fixed base 100. On the basis, the horizontal line rail 301, the mounting plate 302 and the vertical line rail 303 which are mounted on the slider mounting plate 11 are combined, so that the accurate adjustment of the position of the tape splicing platform 31 is realized, and the accurate conveying of the tape is realized.

Specifically, during use, the position of the correction mechanism 300 relative to the fixed base 100 may be initially adjusted by the driving mechanism 400, and then the position of the docking belt platform 31 may be finely and secondarily adjusted by the second air cylinder 33. The mode of twice regulation obviously reduces the position difference existing between the tape receiving platform 31 and the next station, so that the tape receiving platform 31 and the next station are positioned on the same horizontal plane, the deviation is avoided, the quality of products is effectively improved, reworking or material waste caused by errors in the working procedure is reduced, and the productivity of the products is effectively improved.

Example 2

This example is further supplemented with example 1. Referring to fig. 1 to 5 in combination, the conveying mechanism 200 of the present embodiment includes a tape material tray 21, a nip assembly 22, a tension unwind assembly 24, an over-roller rotation detection assembly 25, and a tape cleaning cartridge 26.

Specifically, the tape tray 21, the nip assembly 22, the pass roller assembly 23, the tension unreeling assembly 24, the pass roller rotation detecting assembly 25, and the tape cleaning box 26 are sequentially disposed along the tape conveying direction. Wherein, the strip material is placed on the strip material tray 21, and a second motor 212 is arranged on the strip material tray 21, and the second motor 212 drives the strip material tray 21 to rotate, so that the strip material sequentially passes through the conveying mechanism 200 and the correcting mechanism 300 to the next station. During this process, the hold down assembly 22 protects the strip from damage caused by the strip material hitting the strip material tray 21 during its transport. The roller assembly 23 is driven to rotate during the conveying of the strip, meanwhile, the roller rotation detection assembly 25 precisely controls the length of the strip running through the rotation angle, and the tension unreeling assembly 24 is used for adjusting the length of the unreeled strip.

In particular, the strip cleaning cartridge 26 is positioned between the over-roll rotation detection assembly 25 and the straightening mechanism 300. During the continuous conveying process of the strip, the strip cleaning box 26 is used for cleaning metal powder generated by the strip during the conveying process, ensuring the cleanliness of the strip and avoiding influencing the quality of subsequent products due to the pollution of the strip. For example, if the tab belt is polluted, the battery cell of the product has quality problems, the safety performance is reduced, and safety threat is generated to a user when serious.

In addition, a tape flattening mechanism 500 is provided in the present embodiment, the tape flattening mechanism 500 is provided between the conveying mechanism 200 and the correcting mechanism 300, and the tape flattening mechanism 500 is also fixed to the slider mounting plate 11 so as to achieve a good fit with the correcting mechanism 300. When the strip passes through the strip cleaning box 26 of the conveying mechanism 200 and is about to move to the straightening mechanism 300, the bending degree of the strip generated when passing through the roller is slowed down by the flattening effect of the strip flattening mechanism 500, so that the subsequent strip is conveniently pressed and conveyed by the pressing block 35, and the adhesion with the old strip at the next station is facilitated.

It is added that the automatic belt conveying device in the embodiment can be applied to conveying tab belts in battery production and can be also applied to conveying other material belts.

Example 3

This example is further supplemented with example 2. Referring to fig. 1 in combination, the automatic strip conveying apparatus of this embodiment is provided with two groups of strip conveying modules, which have the same composition and structure and each include a conveying mechanism 200 and a straightening mechanism 300.

When in use, the belt materials on one group of belt material automatic conveying device are mainly used. When the use of the strips of one group of automatic strip conveying device is finished, the other group of strips can be used, so that the strips can be conveyed continuously without stopping.

In the present embodiment, the straightening mechanism 300 and the tape flattening mechanism 500 of the two sets of tape conveying modules are mounted on the same slider mounting plate 11. The strip trays 21 of the two groups of strip transport modules are located at different vertical levels, i.e. there is a height difference between the different strip trays 21, which has the problem that the strip transport is not on the same horizontal line. At this time, the correction mechanism 300 may be adjusted by the driving mechanism 400, so that the correction mechanism 300 slides up and down on the fixed base 100 until the tape splicing platform 31 to be operated and operated is on the same horizontal line with the next station.

Of course, it should be noted that the strip material in this embodiment may be a tab strip material or other material strip material. In addition, the above directional terms and directions are used based on the drawings, and the positions of the conveying mechanism 200 and the correction mechanism 300 and their components in the automatic strip conveying apparatus may be adjusted accordingly as required during the application.

The foregoing is merely illustrative and explanatory of the utility model as it is described in more detail and is not thereby to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and that these obvious alternatives fall within the scope of the utility model.
