The embodiment of the utility model provides a distance changing device and battery manufacturing equipment, which are used for solving the technical problem of low grabbing efficiency of a battery cell.
In the embodiment of the utility model, as shown in fig. 1, the distance changing device comprises a base 1, at least two sliding plates 2, at least two drivers 3, at least two clamps 4 and at least two guide wheels 5; the base 1 is provided with a guide groove 11, and the sliding plate 2 is arranged on the base 1 in a sliding way; the driver 3 is arranged on the base 1, the sliding plate 2 is connected with the output end of the driver 3, and the driver 3 is used for driving the sliding plate 2 to slide along a direction parallel to the first direction; the clamp 4 is arranged on the sliding plate 2 in a sliding manner along a direction parallel to the second direction; the guide wheel 5 is arranged on the clamp 4, and the guide wheel 5 is slidably arranged in the guide groove 11. Wherein, the first direction is perpendicular to the second direction, and when the driver 3 drives the sliding plate 2 to slide, the clamps 4 slide to be arranged in parallel along the direction parallel to the second direction.
Since the driver 3 is disposed on the base 1, the sliding plate 2 is slidably disposed on the base 1, and the sliding plate 2 is connected with the output end of the driver 3, the driver 3 can drive the sliding plate 2 to slide on the base 1. The clamp 4 is slidably provided on the slide plate 2, and the sliding direction of the clamp 4 is perpendicular to the sliding direction of the slide plate 2. The guide wheel 5 is arranged on the clamp 4, and the guide wheel 5 is slidably arranged in the guide groove 11 so as to limit the guide wheel 5 through the guide groove 11, thereby guiding the clamp 4, and enabling the clamp 4 to slide along the extending direction of the guide groove 11 so as to realize the guiding of the clamp 4. Wherein, anchor clamps 4 are used for centre gripping electric core.
When the distance changing device of the embodiment of the utility model is used for distance changing operation, the driver 3 drives the sliding plate 2 to slide along the direction parallel to the first direction. When the sliding plate 2 slides, the clamp 4 is also driven by the sliding plate 2, but due to the limiting effect of the guide groove 11 on the guide wheel 5 and the sliding direction of the clamp 4 is perpendicular to the sliding direction of the sliding plate 2, the clamp 4 can drive the guide wheel 5 to slide in the guide groove 11 so as to play a guiding role on the clamp 4. Finally, the clamps 4 are guided to be arranged in parallel along the direction parallel to the second direction, so that the distance of the clamps 4 is changed, and the clamping jaws can conveniently grasp the electric cores on the clamps 4 arranged in parallel at the same time.
Alternatively, the guide wheel 5 may be a cam structure to reduce the cost of the guide wheel 5. The driver 3 may be a cylinder.
The driver 3 of the embodiment of the utility model can drive the sliding plate 2 to slide along the direction parallel to the first direction; when the sliding plate 2 slides, the clamp 4 which is arranged on the sliding plate 2 in a sliding way is driven by the sliding plate 2; because of the limiting action of the guide groove 11 on the guide wheel 5 and the opposite sliding direction of the clamp 4 to the sliding direction of the sliding plate 2, the clamp 4 can drive the guide wheel 5 to slide in the guide groove 11, so that the guide wheel 5 plays a role in guiding the clamp 4; finally, the guide wheel 5 guides the clamp 4 to be arranged in parallel along the direction parallel to the second direction, so that the clamping jaws can conveniently grasp the electric cores on the clamp 4 arranged in parallel at the same time, and the efficiency of the clamping jaws in grabbing the electric cores is improved.
In one embodiment, as shown in fig. 1, the guide groove 11, the slide plate 2, the driver 3, the jigs 4 and the guide wheels 5 are disposed in a uniform and corresponding manner so as to guide at least two different jigs 4 in a direction parallel to the first direction in the same manner and finally to arrange the jigs 4 side by side in a direction parallel to the second direction.

When the guide wheel 5 is located in the first groove section 111, the interval between the clamps 4 is large, and the battery cells clamped by the clamps 4 are inconvenient to be welded later due to the problem of the placement direction. Therefore, the driver 3 can drive the sliding plate 2 to slide, and then the sliding plate 2 drives the clamp 4 to drive the guide wheel 5 to slide in the guide groove 11 through the clamp 4. The guide wheel 5 is driven by the clamp 4 to pass through the second groove section 112 from the first groove section 111 and finally slide to the third groove section 113. Because the third groove sections 113 are arranged in parallel along the direction parallel to the second direction, the clamps 4 are also arranged in parallel along the direction parallel to the second direction, so that the clamping jaws can conveniently clamp the electrical cores on the clamps 4 arranged in parallel, and the grabbing efficiency of the electrical cores is improved.
Since the orthographic projection of the first groove section 111 and the orthographic projection of the third groove section 113 parallel to the first direction are spaced apart, when the guide wheel 5 is located in the first groove section 111, the clamps 4 are arranged in parallel to the first direction, that is, the short sides of the clamps 4 are arranged opposite to each other. When the guide wheel 5 slides into the third groove section 113, the clamps 4 are arranged side by side in a direction parallel to the second direction, i.e. the long sides of the clamps 4 are arranged opposite each other. Thereby changing the direction of the battery cell on the fixture 4 to facilitate the subsequent welding.

The buffer part 8 collides with the first fixed seat 6 to play a role in buffering and limiting, so that the driver 3 is prevented from being damaged due to hard collision with the first fixed seat 6 when the driver 3 drives the sliding plate 2 to slide; it is also possible to avoid the sliding plate 2 from being separated from the first fixing seat 6, so as to play a role of limiting the sliding plate 2. Wherein the cushioning member 8 may be an elastic member.

The structure can also be simplified.
