Description

Technical Field

[0001] The utility model relates to the field of battery positioning equipment, in particular to an ultra-thin battery precision positioning mechanism. Background Art

[0002] After the soft-pack battery is filled with liquid and packaged, a skirt will be formed on the side of the soft-pack battery. Subsequently, a series of processes such as flattening, cutting, and folding the skirt are required. Therefore, before performing each process, the battery placed on the conveying mechanism needs to be positioned to clarify the position of its skirt so as to facilitate the precise operation of subsequent processing steps. For general soft-pack batteries, the position of its skirt can be detected by CCD camera equipment. However, with the continuous improvement of manufacturing technology, the thickness of soft-pack batteries is getting thinner and thinner. For some ultra-thin soft-pack batteries, the thickness of the battery body is slightly larger than the thickness of the skirt, resulting in an unclear dividing line between the two. It is difficult for the CCD camera to accurately position the skirt. Therefore, it is necessary to produce an ultra-thin battery precision positioning mechanism to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide an ultra-thin battery precision positioning mechanism to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

The vertical slide is fixed to the front side of the mounting vertical plate and corresponds to the left and right sides of the air-avoiding through-hole. The first Z-axis cylinder and the second Z-axis cylinder are both fixed to the mounting vertical plate and correspond to the upper and lower sides of the air-avoiding through-hole, respectively. The first movable vertical plate is fixed to the power output end of the first Z-axis cylinder and is slidingly connected to the vertical slide. The second movable vertical plate is fixed to the power output end of the second Z-axis cylinder and is slidingly connected to the vertical slide. The first limiting plate is fixed to the lower end of the first movable vertical plate. The second limiting plate is fixed to the upper end of the second movable vertical plate and corresponds to the bottom of the first limiting plate. There is a gap between the first limiting plate and the second limiting plate. The first limiting plate and the second limiting plate both correspond to the front side of the air-avoiding through-hole.

[0007] The skirt clamping assembly includes a connecting base plate, a connecting vertical plate, a first Y-axis slide, an elastic connecting piece, a mounting bracket, a clamping cylinder, an upper clamping jaw and a lower clamping jaw. The connecting vertical plate is fixed to the front side of the connecting base plate, the first Y-axis slide is fixed above the connecting base plate, the bottom of the elastic connecting piece is slidably connected to the first Y-axis slide, the front end of the elastic connecting piece is an elastic telescopic end and is elastically connected to the connecting vertical plate, the mounting bracket is fixed above the elastic connecting piece, the clamping cylinder is fixed above the mounting bracket, power output ends are provided on the upper and lower sides of the front end of the clamping cylinder, the upper clamping jaw and the lower clamping jaw are respectively fixed on two groups of power output ends of the clamping cylinder, the upper clamping jaw corresponds to the first limit plate, and the lower clamping jaw corresponds to the second limit plate. The connecting vertical plate, the first Y-axis slide, the elastic connecting piece, the mounting bracket, the clamping cylinder, the upper clamping jaw and the lower clamping jaw are all provided in two groups and correspond to the left and right sides of the connecting base plate.

[0008] Further description of the utility model: a first groove is provided at the lower end of the first limiting plate, the first groove corresponds to the front side of the upper clamping jaw, and a second groove is provided at the upper end of the second limiting plate, the second groove corresponds to the front side of the lower clamping jaw.

[0009] Further description of the utility model: The elastic connecting member includes a lower slider, a second Y-axis slide, an upper slider and a buffer spring. The lower slider is slidably connected to the first Y-axis slide, the second Y-axis slide is fixed above the lower slider, the upper slider is slidably connected to the second Y-axis slide, the mounting bracket is fixed above the upper slider, and the front and rear ends of the buffer spring are respectively fixed on the connecting vertical plate and the upper slider.

[0010] The beneficial effects of the present utility model are as follows: the battery in the previous process is transported to the front side of the skirt limit assembly through the clamping carrier, the first Z-axis cylinder and the second Z-axis cylinder respectively drive the first movable vertical plate and the second movable vertical plate to move on the vertical slide, thereby driving the first limit plate and the second limit plate away from each other, and the first Y-axis driving assembly drives the installation middle plate to move forward, so that the skirt of the battery corresponds to between the first limit plate and the second limit plate, and then the first limit plate and the second limit plate are reset. At this time, the gap between the first limit plate and the second limit plate is between the thickness of the battery body and the thickness of the skirt, and then the second Y-axis driving assembly drives the movable base to move forward so that the upper clamp and the lower clamp correspond to the upper and lower sides of the skirt, and then the clamping cylinder drives the upper clamp and the lower clamp to clamp the skirt, and the second Y-axis driving assembly drives the movable base to pull the skirt backward. When the battery body is blocked by the first limit plate and the second limit plate, the edge of the battery body is close to the first limit plate and the second limit plate, thereby completing the positioning of the battery, and then both the skirt limit assembly and the skirt clamping assembly can be reset. Under the buffering effect of the elastic connector, the backward movement of the connecting base is buffered; the height adjustment component can flexibly adjust the height of the connecting base to accommodate positioning of batteries of different specifications. This design sets up two sets of upper and lower clamps to clamp the left and right sides of the skirt respectively, which can ensure that the battery body is close to the skirt clamping component. Moreover, even if the edge of the battery body and the first limit plate are tilted at a certain angle, the elastic expansion and contraction of the elastic connector can allow the clamps on the left and right sides to move relative to each other along the Y-axis direction, thereby correcting the tilt angle of the battery. The advantage of this design is that it can position ultra-thin batteries with high positioning accuracy and can correct the tilt angle of the battery. BRIEF DESCRIPTION OF THE DRAWINGS

The first Z-axis cylinder 82 and the second Z-axis cylinder 83 are both fixed on the mounting plate 4 and correspond to the upper and lower sides of the air-avoiding through hole 41 respectively. The first movable vertical plate 84 is fixed to the front side of the first Z-axis cylinder 82. The power output end is slidably connected to the vertical slide 81, the second movable vertical plate 85 is fixed to the power output end of the second Z-axis cylinder 83 and is slidably connected to the vertical slide 81, the first limit plate 86 is fixed to the lower end of the first movable vertical, the second limit plate 87 is fixed to the upper end of the second movable vertical plate 85 and corresponds to the bottom of the first limit plate 86, there is a gap between the first limit plate 86 and the second limit plate 87, and the first limit plate 86 and the second limit plate 87 both correspond to the front side of the air-avoiding through hole 41;

[0021] The skirt clamping assembly 9 includes a connecting base plate 91, a connecting vertical plate 92, a first Y-axis slide 93, an elastic connecting member 94, a mounting bracket 95, a clamping cylinder 96, an upper clamping jaw 97 and a lower clamping jaw 98. The connecting vertical plate 92 is fixed to the front side of the connecting base plate 91, the first Y-axis slide 93 is fixed above the connecting base plate 91, the bottom of the elastic connecting member 94 is slidably connected to the first Y-axis slide 93, the front end of the elastic connecting member 94 is an elastic telescopic end and is elastically connected to the connecting vertical plate 92, and the mounting bracket 95 is fixed above the elastic connecting member 94 The clamping cylinder 96 is fixed above the mounting bracket 95, and power output ends are provided on the upper and lower sides of the front end of the clamping cylinder 96. The upper clamping jaw 97 and the lower clamping jaw 98 are respectively fixed on the two groups of power output ends of the clamping cylinder 96. The upper clamping jaw 97 corresponds to the first limit plate 86, and the lower clamping jaw 98 corresponds to the second limit plate 87. The connecting vertical plate 92, the first Y-axis slide 93, the elastic connecting member 94, the mounting bracket 95, the clamping cylinder 96, the upper clamping jaw 97 and the lower clamping jaw 98 are all arranged in two groups and correspond to the left and right sides of the connecting base plate 91.

[0022] The battery in the previous process is transported to the front side of the skirt limit assembly 8 through the clamping carrier, and the first Z-axis cylinder 82 and the second Z-axis cylinder 83 respectively drive the first movable vertical plate 84 and the second movable vertical plate 85 to move on the vertical slide 81, thereby driving the first limit plate 86 and the second limit plate 87 away from each other, and the first Y-axis drive assembly 2 drives the installation middle plate 3 to move forward, so that the skirt of the battery corresponds to the first limit plate 86 and the second limit plate 87. Then, the first limit plate 86 and the second limit plate 87 are reset. At this time, the gap between the first limit plate 86 and the second limit plate 87 is Between the thickness of the battery body and the thickness of the skirt, the second Y-axis drive assembly 5 then drives the movable base 6 forward, so that the upper clamping jaw 97 and the lower clamping jaw 98 correspond to the upper and lower sides of the skirt. The clamping cylinder 96 then drives the upper clamping jaw 97 and the lower clamping jaw 98 to clamp the skirt. The second Y-axis drive assembly 5 drives the movable base 6 to pull the skirt backward. When the battery body is blocked by the first limit plate 86 and the second limit plate 87, the edge of the battery body is close to the first limit plate 86 and the second limit plate 87, thereby completing the positioning of the battery. Then, the skirt limit assembly 8 and the skirt clamping assembly 9 can both be reset. Under the buffering action of the elastic connector 94, the backward movement of the connecting base 91 is buffered; the height adjustment assembly 7 can flexibly adjust the height of the connecting base 91 to accommodate batteries of different specifications for positioning. This design employs two sets of upper and lower clamping jaws 97 and 98, respectively, to clamp the left and right sides of the skirt. This ensures that the battery body is firmly against the skirt clamping assembly 9. Furthermore, even if the edge of the battery body is tilted at a certain angle relative to the first limiting plate 86, the elastic connector 94 allows the left and right clamping jaws to move relative to each other along the Y-axis, thereby correcting the battery's tilt. This design offers the advantage of being able to position even ultra-thin batteries with high accuracy and accurately correcting the battery's tilt.

[0023] The lower end of the first limiting plate 86 is provided with a first groove 861 corresponding to the front side of the upper clamping jaw 97 , and the upper end of the second limiting plate 87 is provided with a second groove 871 corresponding to the front side of the lower clamping jaw 98 .

[0024] By providing the first groove 861 and the second groove 871 , the upper clamping jaw 97 and the lower clamping jaw 98 can be allowed to move to the front side of the first limiting plate 86 and the second limiting plate 87 to increase the clamping distance, which can accommodate positioning of batteries of more different specifications.

[0025] The elastic connecting member 94 includes a lower slider 941, a second Y-axis slide 942, an upper slider 943 and a buffer spring. The lower slider 941 is slidingly connected to the first Y-axis slide 93, the second Y-axis slide 942 is fixed above the lower slider 941, the upper slider 943 is slidingly connected to the second Y-axis slide 942, the mounting bracket 95 is fixed above the upper slider 943, and the front and rear ends of the buffer spring are respectively fixed on the connecting vertical plate 92 and the upper slider 943.

[0026] The position of the elastic connecting member 94 is adjustable on the first Y-axis slide 93. During the process of pulling the skirt, after the battery body contacts the first limit plate 86 and the second limit plate 87, the upper slider 943 stops running. At this time, the lower slider 941 and the second Y-axis slide 942 move backward relative to each other, and the buffer spring is compressed, thereby playing a buffering role.

[0027] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
