Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery manufacturing, and particularly relates to a synchronous distance-changing device for conveying batteries. Background Art

[0002] At present, the country vigorously promotes new energy, and the lithium battery industry has also developed greatly. In this case, the production quality requirements for lithium batteries are getting higher and higher. Therefore, it is necessary to strengthen the effective control of the battery production process. In the process of conveying batteries, the distance between the conveying components is too large and the speed is too fast, resulting in unclear results of the detection component's photographic inspection of the battery. In addition, the existing technology does not have a variable pitch mechanism, and directly transfers the battery through the meshing of the material wheel of the mechanism. Therefore, the speed of the conveying component cannot be effectively controlled. This component mainly improves the problem of battery cup spacing.

[0003] In the existing utility model patent (patent number: CN114516449A), a synchronous variable-pitch conveying device is involved. In this patent, by adjusting the output of the power source, the transfer speed of the first transmission belt and the transfer speed of the second transmission belt maintain a certain speed difference, so that the distance between the two adjacent first slides and the second slide will change equidistantly, and the changed bubble spacing will be consistent with the spacing requirements of the subsequent feeding grid conveying device; when the material on the tray is taken away, the transmission belt moves in the opposite direction, allowing the slide to return quickly and wait for the next material to be received, and the cycle is repeated. Summary of the invention

[0004] In view of the above problems, the utility model proposes a synchronous distance-changing device for conveying batteries.

[0005] The synchronous pitch-changing device for conveying batteries comprises an end face detection drive assembly, the end face detection drive assembly comprises a horizontally extending drive shaft, and the extension direction of the drive shaft is defined as the left and right direction; a synchronous wheel is provided in the middle of the drive shaft; a synchronous belt is sleeved on the synchronous wheel, and shaft sleeves and deep groove ball bearings are respectively provided at the left and right ends of the synchronous wheel; a deep groove bearing is respectively provided at the left and right ends of the drive shaft; a avoidance cam is respectively sleeved on the deep groove bearing; the side of the two avoidance cams close to each other is defined as the inner side, and the side away from each other is defined as the outer side; the outer side of the avoidance cam is connected to the drive shaft through a avoidance cam stop ring, and a side shift fork mechanism is provided on the inner side, and the side shift fork mechanism comprises a side shift fork, and the side shift fork is provided with an inner groove that can clamp the end of the battery, and the side shift fork can be connected to the linear guide rail that can slide left and right through the guide rail connecting block, and the linear guide rail is connected to the drive shaft;

[0006] An inner limit cam is respectively provided on the left and right sides of the synchronous wheel, and the two inner limit cams are connected and fixed to each other by a fixing rod, and an outer limit cam mechanism is provided above the two inner limit cams; an intermediate channel for accommodating the battery to pass through is formed between the inner limit cam and the outer limit cam mechanism, so as to achieve the effect of limiting the battery; a battery holder cup with several battery holder cups is connected to the synchronous wheel belt, and the battery holder cup is provided with a groove for accommodating the battery. The side shift fork can shift the external battery into the groove of the battery holder cup, and make the battery approach the driving shaft as the battery holder cup rotates; when the side shift fork conveys the battery to the vertical upper side of the driving shaft, the side shift fork slides outward under the shifting of the outer limit cam mechanism, so that the battery can slide into the battery holder cup below by itself.

[0007] More specifically, the gap distance between the outer limit cam mechanism and the inner limit cam gradually decreases along the rotation direction of the synchronous belt.

[0008] The working steps of the utility model include:

[0009] 1. The driving shaft rotates, driving the synchronous wheel to rotate, driving the battery holder to move synchronously, and the linear guide fixed on the driving shaft runs accordingly.

[0010] 2. When the sliding assembly runs to the engagement point of the external material wheel mechanism, the side forks fixed on both sides of the guide rail connecting block move inward for a distance under the push of the cam, and the inner grooves of the side forks clamp the two ends of the battery. The battery and the drive shaft form a synchronous motion relationship. At this time, the battery also rotates around the drive shaft under the joint constraints of the inner limit cam and the outer limit cam assembly, and the rotation radius gradually decreases.

[0011] 3. When the battery moves to a position close to the vertical upper side of the drive shaft, the dynamic side forks on both sides fixed on the guide rail slider move outward for a certain distance under the push of the inner limit cam, and the two ends of the battery are separated from the inner groove of the side fork. The battery is caught by the battery holder on the synchronous belt and transported.

[0012] 4. The battery is synchronously and equidistantly conveyed to the battery holder. During operation, the external limit cam controls the range and speed of battery movement. After the conveying is completed, the dynamic side forks on both sides are synchronously and equidistantly reset.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model realizes dynamic continuous material distance variation through the combination mechanism of cam, fork and guide rail, reduces the spacing of batteries in the end face detection section, reduces the moving speed of batteries at the same beat, improves the clarity of battery photography, and thus improves the accuracy of battery detection.
