DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to more clearly understand the structure of the discharging device provided in the embodiment of the present application, the structure of the material strip 001 and the structure of the battery cell are now described. The material strip 001 contains multiple Figure 1 The illustrated battery cell units 01 are spaced apart from each other along the extension direction of the material strip 001 and connected by a separator 02. It should be understood that each battery cell unit 01 includes a central separator 011 and a first electrode piece 012 and a second electrode piece 013 disposed on either side of the central separator 011, wherein the first electrode piece 012 and the second electrode piece 013 have opposite polarity. When the first electrode piece 012 is a positive electrode piece, the second electrode piece 013 is a negative electrode piece. Conversely, when the first electrode piece 012 is a negative electrode piece, the second electrode piece 013 is a positive electrode piece. It is worth noting that the central separator 011 in the battery cell unit 01 and the separator 02 between adjacent battery cell units 01 are a continuous structure. After the material strip 001 is discharged by the discharging device, several battery cell units 01 are stacked to form a battery cell structure.

[0035] An embodiment of the present application provides a discharging device, which is used to transmit a material belt 001. Figure 2 This is a schematic diagram of the three-dimensional structure of the discharging device provided in the embodiment of the present application. Figure 3 for Figure 2 Side view of the structure. Figure 2 refer to Figure 3 The discharging device provided in the embodiment of the present application includes a base 1; a detection mechanism 2, the detection mechanism 2 is fixed relative to the base 1, and the detection mechanism 2 is used to detect the offset of the material belt 001 along the first direction a, and the first direction a is parallel to the width direction of the material belt 001; a discharging mechanism 3 for transmitting the material belt 001, and the discharging mechanism 3 can be movably installed on the base 1 along the first direction a. It should be understood that the detection mechanism 2 is not necessarily provided on the base 1, and it only needs to be fixed relative to the base 1. Among them, the detection mechanism 2 is fixed relative to the base 1 means that the detection mechanism 2 is fixed relative to the base 1 during measurement. Of course, when using the discharging device provided in the embodiment of the present application, the setting position of the detection mechanism 2 can be changed according to needs.

[0036] It should be noted that the discharging device provided in the embodiment of the present application measures the offset of the material strip 001 in the first direction a through the detection mechanism 2. Based on this, the discharging mechanism 3 can be controlled to move relative to the base 1 in the first direction a to correct the offset of the material strip 001. Specifically, the offset of the material strip 001 can be offset by controlling the movement of the discharging mechanism 3 relative to the base 1 in the first direction a.

[0037] Therefore, the discharging device provided in the embodiment of the present application can be flexibly adjusted along the first direction a to achieve a deviation correction effect of the material belt 001, thereby improving the accuracy of the device's discharging.

[0038] It should be understood that when using the discharging device provided in the embodiments of the present application, the initial position of the discharging mechanism 3 can be set to align with the center of the base 1. Initially, the material strip 001 is aligned with the center of the discharging mechanism 3. As the material strip 001 moves, the material strip 001 may gradually deviate from the discharging mechanism 3. At this time, the discharging mechanism 3 begins to move to compensate, so that the material strip 001 is aligned with the center of the base 1.

[0039] Specifically, when the material belt 001 is transported in the discharging mechanism 3, there will be a set transport direction, for example, Figure 2 As shown, the material strip 001 is transported along direction b. When the material strip 001 is transported along direction b, there may be a deviation in the direction a perpendicular thereto. Figure 2 The dashed line M is the preset edge line of the material strip 001, for example. Figure 2 In the structure shown, there is an offset S between the material strip 001 and the dotted line M. It should be understood that the material strip 001 may also exceed the edge line M, which will not be described in detail here.

[0040] Please continue to refer to Figure 2 In the illustrated structure, due to the offset S between the material strip 001 and the dotted line M, the material strip 001 must move a distance S along the branch direction a1 of the direction a to reach the preset position. Based on this, the operator can control the dispensing mechanism 3 to move a distance S along the direction a1, causing the material strip 001 to move with the dispensing mechanism 3 and reach the preset position. It is worth noting that when the edge of the material strip 001 coincides with the dotted line M, the material strip 001 is aligned with the center of the base 1.

[0041] It should be noted that, in one possible embodiment, the position of the discharging mechanism 3 relative to the base 1 can be adjusted in real time along direction a according to the transmission status of the material belt 001 to improve production efficiency; in another possible embodiment, the position of the discharging mechanism 3 relative to the base 1 can be adjusted along direction a by stopping the machine to ensure the adjustment accuracy.

[0042] When the discharging mechanism 3 is installed on the base 1, in one embodiment, the discharging mechanism 3 can be installed on the base 1 through at least one set of slide rail components. Figure 3 As shown, the discharging mechanism 3 is mounted on the base 1 through four sets of slide rail assemblies. It should be understood that due to the angle, Figure 3Only two sets of slide rail assemblies are shown. Specifically, the base 1 is provided with four slide rails 4, each two slide rails 4 forming a group, arranged relative to each other along the first direction a, and each slide rail 4 in each group extends along the first direction a; the two sets of slide rails 4 are arranged relative to each other along the extension direction of the base 1. The discharging mechanism 3 is provided with a chute structure, which cooperates with the slide rail 4 to achieve the movement effect of the discharging mechanism 3 relative to the base 1. Of course, the chute structure can also be provided on the base 1 and the slide rail 4 can be provided on the discharging mechanism 3. The specific configuration can be based on needs and will not be repeated here. As for the number of slide rail assemblies, it can also be set according to needs.

[0043] It is worth noting that the structure that can achieve the movement of the discharging mechanism 3 relative to the base 1 along the first direction is not limited to the above-mentioned slide rail assembly, and can also be other components to achieve the movement effect of the discharging mechanism 3 relative to the base 1.

[0044] In one embodiment, the detection mechanism 2 illustratively includes at least one visual camera. It should be understood that when the detection mechanism 2 includes multiple visual cameras, the multiple cameras can be spaced apart along direction b to improve detection accuracy. Of course, the detection structure 3 is not limited to detecting the edge position of the material strip 001 to determine the offset. For example, a specific location on the material strip 001 can also be selected for detection, which will not be further described here.

[0045] In one embodiment, the discharging device provided in the embodiment of the present application further includes a driving mechanism disposed on the base 1, the driving mechanism being configured to control the discharging mechanism 3 to move along the first direction a according to the offset S. Exemplarily, the driving mechanism includes a motor or a cylinder. When the driving mechanism is a motor, the output end of the motor is connected to a screw assembly, and the screw assembly drives the discharging mechanism 3 to move relative to the base 1 along the extension direction of the slide rail 4.

[0046] It should be noted that the drive mechanism can autonomously drive the discharging mechanism 3 to move based on the offset S measured by the detection mechanism 2, thereby precisely controlling the movement of the discharging mechanism 3. For example, in one specific embodiment, the motor and the lead screw can be controlled by a programmable controller to control the movement of the discharging mechanism 3. Of course, manual driving by an operator is also possible, which will not be described in detail here.

[0047] In one embodiment, the discharging mechanism 3 exemplarily includes a support seat 5 and a discharging assembly, wherein: the support seat 5 can be movably mounted on the base 1 along the first direction a; the discharging assembly is arranged on the side of the support seat 5 away from the base 1, and the discharging assembly has a discharging port. Exemplarily, the discharging direction of the discharging port has an angle with the horizontal plane, and exemplary, the angle ranges from -90° to 90°. It should be noted that the discharging angle is convenient for setting up subsequent structures such as the receiving station. It should be understood that, if Figure 3The downwardly inclined discharging direction c1 is shown to be within the range of -90° to 0° with respect to the horizontal plane. Correspondingly, when the direction c1 is upwardly inclined, it is within the range of 0° to 90°.

[0048] In one embodiment, the discharging direction of the discharging port in the discharging device provided in the embodiment of the present application is adjustable. For example, the discharging direction of the discharging port can be adjusted according to the needs. Figure 3 The direction c1 in is adjusted to Figure 4 Direction c2 in order to adapt to production needs and broaden the application scenarios. It is worth noting that Figure 3 The direction c1 in Figure 4 The direction c2 in the figure is in the range of -90° to 90°.

[0049] Of course, the discharging direction of the discharging port is not limited to -90° to 90°. This is just a schematic illustration. The discharging direction is possible in 360° directions. It is only necessary to set the relevant structural position.

[0050] Please refer to Figure 5 In the structure shown, in one possible embodiment, the discharging assembly includes a first wheel body 6 and a second wheel body 7, the axis lines of the first wheel body 6 and the second wheel body 7 are parallel to the first direction a, and a discharging port is formed between the first wheel body 6 and the second wheel body 7. Figure 5 As shown, in one embodiment, the first wheel body 6 and the second wheel body 7 are connected by a connecting structure. It is worth noting that the surfaces of the first wheel body 6 and the second wheel body 7 can be in close contact before the material strip 001 enters between the first wheel body 6 and the second wheel body 7. After the material strip 001 enters between the first wheel body 6 and the second wheel body 7, the first wheel body 6 and the second wheel body 7 form a discharge port.

[0051] For the sake of convenience, the second wheel body 7 is exemplarily arranged below the first wheel body 6, and the material discharging direction of the discharging port is obliquely downward. It should be understood that the arrangement direction of the first wheel body 6 and the second wheel body 7 is not limited to Figure 5 The arrangement direction shown in the figure can adjust the arrangement positions of the first wheel body 6 and the second wheel body 7 according to needs.

[0052] In one embodiment, in order to promptly detect whether the material belt 001 is offset relative to the discharge port and improve the discharge efficiency, at least one visual sensor of the detection mechanism 2 can be set on the feed side of the discharge port.

[0053] It is worth noting that there are many structures for realizing the adjustable discharging angle of the discharging assembly. Figure 5In the illustrated structure, the discharging assembly and support base 5 are hingedly connected via a hinge shaft 8. An adjustment assembly is also provided between the discharging assembly and support base 5. This adjustment assembly is located on the side of the hinge shaft 8 facing away from the discharging port to adjust the discharging assembly's rotation angle about the hinge shaft 8. Specifically, the adjustment assembly includes a first adjustment portion provided on the support base 5 and a second adjustment portion provided on the discharging assembly.

[0054] It should be understood that there are many possible structures of the first adjustment portion and the second adjustment portion, including at least one of the following embodiments.

[0055] In one possible embodiment, the first adjustment part has an arc-shaped adjustment section, the plane where the arc-shaped adjustment section is located is perpendicular to the first direction a, and the center line of the arc-shaped adjustment section is collinear with the axis line of the hinge shaft 8, and the second adjustment part can move relative to the first adjustment part along the extension direction of the arc-shaped adjustment section.

[0056] It should be noted that by adjusting the position of the second adjustment portion relative to the arc-shaped adjustment section of the first adjustment portion, the discharging direction of the discharging port can be changed around the hinge axis 8. For example, when the second adjustment portion moves upward clockwise relative to the arc-shaped adjustment portion D, the discharging direction moves downward clockwise.

[0057] In a specific embodiment, the first adjustment portion has an arcuate groove, which forms an arcuate adjustment section, and the second adjustment portion has a protrusion, which is embedded in the arcuate groove and can move along the extension direction of the arcuate groove. In another specific embodiment, please continue to refer to Figure 5 In the illustrated structure, the first adjustment section has multiple holes spaced apart to form an arc-shaped adjustment segment, while the second adjustment section has a protrusion or opening. By adjusting the alignment of the holes in the first adjustment section with the opening or protrusion in the second adjustment section, the dispensing direction can be adjusted.

[0058] In another possible implementation, please refer to Figure 6 In the structure shown, the first adjustment portion is a support structure 9 provided on the support base 5, and the second adjustment portion is a protruding structure 10 provided on the discharging assembly. Specifically, the support structure 9 can move vertically and horizontally relative to the support base 5, and the movement direction of the support structure 9 is perpendicular to the first direction a.

[0059] For example, the support structure 9 is a telescopic rod or a telescopic frame, and the raised structure 10 is a raised block or a pin structure. Figure 6 In the structure shown, an accommodating groove is provided at the end of the supporting structure 9 , and the accommodating groove is used to accommodate the protruding structure 10 , and the supporting structure 9 can limit the height of the protruding structure 10 .

[0060] It should be noted that when the rotation angle of the discharging assembly around the hinge shaft 8 needs to be adjusted, the protruding structure 10 can be separated from the receiving groove, and then the supporting structure 9 can be moved simultaneously in the vertical and horizontal directions. After the supporting structure 9 is moved into place, the protruding structure 10 can be dropped into the receiving groove to complete the angle adjustment. Figure 7 As shown, the adjustment component is composed of Figure 7 Move the middle dotted line position to Figure 7 The solid line position is used to adjust the discharging direction of the discharging component.

[0061] Of course, when the support structure 9 moves, the protrusion mechanism 10 may not be separated from the receiving groove. Specifically, the protrusion structure 10 can rotate relative to the discharging assembly. When the support structure 9 moves in the vertical direction or the horizontal direction, the protrusion structure 10 can move with the support structure 9. It is worth noting that when the protrusion structure moves with the support structure 9, the movement trajectory of the protrusion structure 10 is Figure 6 The middle arc dotted line shows that the center of the arc dotted line is the axis center line of the hinge shaft 8.

[0062] Of course, in conjunction with the structure of the first adjustment part and the second adjustment part, the discharging device provided in the embodiment of the present application may further include a locking structure 11 provided between the first adjustment part and the second adjustment part. The locking structure 11 is used to limit the position of the second adjustment part relative to the first adjustment part.

[0063] It should be noted that the locking structure 11 can lock the relative position of the second adjustment part with respect to the first adjustment part after each angle adjustment to fix the discharging direction. Figure 5 In the structure shown, when both the first adjustment portion and the second adjustment portion are hole structures, the locking structure 11 can be a positioning pin. When in use, after the second adjustment portion is aligned with the hole of the first adjustment portion, the locking structure 11 can be inserted into the two holes for locking.

[0064] In a second aspect, an embodiment of the present application further provides a lamination device, comprising any one of the discharging devices provided by the above technical solution.

[0065] In the lamination apparatus provided in the embodiment of the present application, the discharging device measures the offset of the material strip 001 in the first direction a via the detection mechanism 2. Based on this, the discharging mechanism 3 can be controlled to move relative to the base 1 in the first direction a to correct the offset of the material strip 001. Specifically, the offset of the material strip 001 can be offset by controlling the movement of the discharging mechanism 3 relative to the base 1 in the first direction a.

[0066] Therefore, the discharging device in the lamination equipment provided in the embodiment of the present application can be flexibly adjusted along the first direction a to achieve the deviation correction effect of the material belt 001, thereby improving the accuracy of the device's discharging.

[0067] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
