Description

Technical Field

[0001] The present application relates to the field of processing equipment, and in particular to a battery cell gluing device and battery production equipment. Background Art

[0002] The next process of multi-JR battery cells (multiple parallel battery cells in an aluminum shell, JR stands for jelly roll, representing the core package) after the top cover is welding is generally core bonding and gluing, commonly known as Mylar wrapping (Mylar film, a polyester film with high surface flatness, good transparency and strong mechanical flexibility).

[0003] During the Mylar wrapping process, the tape cannot be folded. This is primarily due to the tail swinging of the battery cells during winding, causing the outermost electrodes to protrude beyond the inner electrodes. If the pusher assembly or roller comes into direct contact with the battery cells during folding, the bottom of the cell can be damaged, leading to powder loss. If there is a gap between the pusher assembly or roller and the cell, the tape cannot be adhered to the bottom of the cell. Consequently, repeated adjustments to the relative position of the pusher assembly or roller and the cell are required during folding, wasting significant time on site, significantly reducing production capacity, and making it impossible to control cell quality.

Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] Example 1

[0042] See also Figures 1 to 5 As shown, the battery cell gluing device provided in the present application includes a gluing mechanism 101, a positioning mechanism 102 and a shifting mechanism.

[0043] The positioning mechanism 102 is used to secure the battery cell 103. The shifting mechanism is connected to the positioning mechanism 102 and / or the gluing mechanism 101 to drive the positioning mechanism 102 and the gluing mechanism 101 toward or away from each other. The gluing mechanism 101 includes a soft folding brush that moves along the folding direction of the adhesive tape 104 to scrape the adhesive tape 104, thereby folding the adhesive tape 104 along the contour of the battery cell 103 and affixing it to the adhesive surface 105 of the battery cell 103.

[0044] Specifically, before gluing the battery cell 103, the distance between the positioning mechanism 102 and the gluing mechanism 101 is relatively large, allowing space for the battery cell 103 to be installed on the positioning mechanism 102. When gluing the battery cell 103, the battery cell 103 is first placed on the positioning mechanism 102. The positioning mechanism 102 can position the battery cell 103 to ensure that the battery cell 103 does not move during the gluing process, thereby ensuring that the adhesive tape 104 and the battery cell 103 are more securely attached. After the battery cell 103 is positioned, the shifting mechanism drives the positioning mechanism 102 and the gluing mechanism 101 closer to each other, so that the part of the battery cell 103 to be folded is aligned with the position of the gluing mechanism 101.

[0045] Furthermore, one side of the tape 104 is sticky and is used to adhere to the battery cell 103. The adhesive application mechanism 101 includes a soft adhesive folding brush, which can scrape the tape 104 from the other side of the tape 104, so that the tape 104 can be folded along the contour edge of the battery cell 103 and adhered to the surface of the battery cell 103. Due to the soft nature of the adhesive folding brush, the adhesive folding brush can deform to correspond to the contour of the battery cell 103 surface, thereby pressing the adhesive tape 104 to ensure reliable adhesion. The adhesive folding brush also has a cushioning function when colliding with the battery cell 103, preventing the battery cell 103 from being damaged and powdered.

[0046] The battery cell gluing device provided in the present application can ensure that the tape 104 is reliably adhered to the surface of the battery cell 103 by setting a soft folding brush to move along the folding direction of the tape 104 to scrape the tape 104, and can prevent the battery cell 103 from being damaged and powdered, thereby improving production efficiency and product quality.

[0047] In an optional solution of this embodiment, the folding brush includes a long-side brush module, which includes a first brush module and a second brush module. The first brush module includes a first brush 106 and a first drive device 107. The first brush 106 is opposite to one long side of the adhesive surface 105. The first drive device 107 is used to drive the first brush 106 to move along the folding direction of the corresponding adhesive tape 104. The second brush module includes a second brush 108 and a second drive device 109. The second brush 108 is opposite to the other long side of the adhesive surface 105. The second drive device 109 is used to drive the second brush 108 to move along the folding direction of the corresponding adhesive tape 104.

[0048] In this embodiment, Figure 1 As shown, the two first sides in the length direction and the two second sides in the thickness direction of the battery cell 103 are surrounded to form an adhesive surface 105. When the positioning mechanism 102 positions the battery cell 103, the large surfaces of the battery cell 103 (formed by the two first sides in the length direction and the two third sides in the width direction of the battery cell 103) are spaced apart in the vertical direction. The adhesive tape 104 extending from the first side from the upper and lower large surfaces needs to be folded and adhered to the adhesive surface 105. Therefore, the present application provides a long-side brush module to fold and adhere the above-mentioned adhesive tape 104.

[0049] Specifically, the long-side brush module includes a first brush module and a second brush module. The first brush module is opposite the upper first side. The first brush module includes a first brush 106 and a first drive device 107. The first drive device 107 can drive the first brush 106 downward in a direction perpendicular to the first side (vertical direction), so that the first brush 106 scrapes the tape 104 extending from the upper large surface downward, thereby adhering the tape 104 to the adhesive surface 105.

[0050] The second brush module is opposite to the first side below and includes a second brush 108 and a second drive device 109. The second drive device 109 can drive the second brush 108 to move upward in a direction perpendicular to the first side (vertical direction) so that the second brush 108 can scrape the tape 104 extending from the large surface below upward, thereby adhering the tape 104 to the adhesive surface 105.

[0051] In the optional solution of this embodiment, Figure 1 and Figure 4As shown, adhesive tape 104 extends from the upper large surface at both ends of the adhesive surface 105 in the longitudinal direction. Therefore, a first brush 106 is provided at each end of the upper long side of the adhesive surface 105, and the two first brushes 106 are connected by a first connecting frame 110. A first drive device 107 is specifically a cylinder, and the drive end of the cylinder is connected to the first connecting frame 110. When the first drive device 107 is activated, it can drive the first brushes 106 on both sides to move synchronously. Only one first drive device 107 is required to achieve synchronous folding and adhesion of the adhesive tape 104 on both sides, which is more cost-effective and ensures the consistency of the movement of the first brush 106 and the second brush 108 on both sides.

[0052] like Figure 1 and Figure 4 As shown, adhesive tape 104 extends from the lower large surface at both ends of the adhesive surface 105 in the longitudinal direction. Therefore, a second brush 108 is provided at each end of the lower long side of the adhesive surface 105, and the two second brushes 108 are connected by a second connecting frame 111. The second drive device 109 is specifically a cylinder, and the drive end of the cylinder is connected to the second connecting frame 111. When the second drive device 109 is activated, it can drive the second brushes 108 on both sides to move synchronously. Only one second drive device 109 is required to achieve synchronous folding and adhesion of the adhesive tape 104 on both sides, which is more cost-effective and ensures the consistency of the movement of the first brush 106 and the second brush 108 on both sides.

[0053] In an optional solution of this embodiment, the long side brush module also includes a long side guide component 112, the guiding direction of the long side guide component 112 is the folding direction of the tape 104 at the long side of the adhesive surface 105; the long side guide component 112 is connected to the first connecting frame 110 and the second connecting frame 111 to guide the movement of the first brush 106 and the second brush 108.

[0054] In this embodiment, Figure 2 As shown, the first brush 106 and the second brush 108 both move along the same straight line and in a direction perpendicular to the first side (vertical direction), but the movement directions of the first brush 106 and the second brush 108 are opposite, so a long side guide assembly 112 is provided to guide the movement of the two. Specifically, the glue-applying mechanism 101 includes a first base to support the folding glue soft brush. The long side guide assembly 112 includes a slide rail and two sliders slidably mounted on the slide rail. The slide rail is vertically mounted on the first base, and the upper slider is connected to the first connecting frame 110, and the lower slider is connected to the second connecting frame 111, so as to guide the movement of the first brush 106 and the second brush 108 respectively.

[0055] In an optional scheme of this embodiment, the folding soft brush includes a short-side brush module, and the short-side brush module includes a third brush module and a fourth brush module; the third brush module includes a third brush 113 and a third driving device 114, and the third brush 113 is opposite to the short side of one side of the adhesive surface 105; the third driving device 114 is used to drive the third brush 113 to move along the folding direction of the corresponding tape 104; the fourth brush module includes a fourth brush 115 and a fourth driving device 116, and the fourth brush 115 is opposite to the other short side of the adhesive surface 105; the fourth driving device 116 is used to drive the fourth brush 115 to move along the folding direction of the corresponding tape 104.

[0056] In this embodiment, Figure 1 and Figure 4 As shown, when the positioning mechanism 102 positions the battery cell 103, the end faces of the battery cell 103 (formed by the two second sides in the thickness direction and the two third sides in the width direction of the battery cell 103) are arranged horizontally at intervals. The tape 104 extending from the two left rear end faces with the second side edges needs to be folded and adhered to the adhesive surface 105. Therefore, the present application provides a short-side brush module to fold and adhere the tape 104.

[0057] Specifically, the short-side brush module includes a third brush module and a fourth brush module. The third brush module is opposite the second side on the left. The third brush module includes a third brush 113 and a third drive device 114. The third drive device 114 is specifically a cylinder that drives the third brush 113 to move rightward in a direction perpendicular to the second side (horizontally), so that the third brush 113 scrapes the tape 104 extending from the left end face to the right, thereby adhering the tape 104 to the adhesive surface 105.

[0058] The fourth brush module is opposite to the second side on the right side. The fourth brush module includes a fourth brush 115 and a fourth drive device 116. The fourth drive device 116 is specifically a cylinder that can drive the fourth brush 115 to move leftward in a direction perpendicular to the second side (horizontally) so that the fourth brush 115 scrapes the tape 104 extending from the right end surface to the left, thereby adhering the tape 104 to the adhesive surface 105.

[0059] It should be noted that when the long-side brush module is running, the short-side brush module needs to retreat and avoid; when the end-side brush module is running, the long-side brush module needs to retreat and avoid to avoid affecting the other side's scraping action of the tape 104.

[0060] In an optional solution of this embodiment, the short side brush module also includes a first short side guide component 117 and a second short side guide component 118. The guiding direction of the first short side guide component 117 and the second short side guide component 118 is the folding direction of the tape 104 at the short side of the adhesive surface 105; the first short side guide component 117 is connected to the third brush 113 to guide the movement of the third brush 113; the second short side guide component 118 is connected to the fourth brush 115 to guide the movement of the fourth brush 115.

[0061] In this embodiment, although the third brush 113 and the fourth brush 115 move along the same straight line and in a direction perpendicular to the second side (horizontally), the distance between the third brush 113 and the fourth brush 115 is too long, so a separate guide assembly is provided for each to simplify the structure. Specifically, the first short side guide assembly 117 includes a slide rail and a slider slidably mounted on the slide rail. The slide rail is horizontally mounted on the first base, and the slider is connected to the third brush 113 to guide the movement of the third brush 113. The second short side guide assembly 118 includes a slide rail and a slider slidably mounted on the slide rail. The slide rail is horizontally mounted on the first base, and the slider is connected to the fourth brush 115 to guide the movement of the fourth brush 115.

[0062] In an optional solution of this embodiment, the gluing mechanism 101 also includes a pressure component; the pressure component is opposite to the glue area of ​​the adhesive surface 105; the pressure component includes a pressure piece 119 and a fifth drive device 120, and the fifth drive device 120 is used to drive the pressure piece 119 close to or away from the adhesive surface 105 to apply pressure to the tape 104 after the glue area is folded.

[0063] In this embodiment, after the long-side brush module and the short-side brush module scrape and fold the tape 104, a pressure assembly can be used to apply pressure to the folded adhesive area of ​​the tape 104 to ensure a tight bond between the tape 104 and the adhesive surface 105 of the battery cell 103. Specifically, the pressure assembly includes a pressure member 119 and a fifth drive device 120. The pressure member 119 is opposite the adhesive area, and the fifth drive device 120 is a cylinder that drives the pressure member 119 to extend and apply pressure to the tape 104. When the long-side brush module and the short-side brush module are in operation, the cylinder drives the pressure member 119 to retract and avoid the adhesive area.

[0064] Furthermore, the pressure surface of the pressure member 119 is provided with a soft rubber pad to prevent the pressure member 119 from damaging the battery cell 103. A clearance space is provided in the middle of the pressure surface to avoid the gap with the limit stopper 122 of the positioning mechanism 102 located on the adhesive surface 105.

The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0067] See also Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, the positioning mechanism 102 includes a support platform 121, a limit stopper 122, and a pushing assembly. The support platform 121 is used to support the battery cell 103. The limit stopper 122 is located on the side of the battery cell 103 close to the gluing mechanism 101 to position the adhesive surface 105. The blocking area of ​​the limit stopper 122 is offset from the adhesive area of ​​the adhesive surface 105 so that the limit stopper 122 does not block the adhesive area of ​​the adhesive surface 105. The pushing assembly is located on the side of the battery cell 103 away from the gluing mechanism 101. The pushing assembly includes the pushing member 123 and a sixth driving device 124. The sixth driving device 124 is used to drive the pushing member 123 toward or away from the battery cell 103 so that the battery cell 103 abuts against the limit stopper 122.

[0068] In this embodiment, when positioning the battery cell 103, the battery cell 103 can be placed on the support platform 121, which can support the battery cell 103 from the bottom. The sixth driving device 124 drives the pushing member 123 to move the battery cell 103 toward the limit stopper 122 until the battery cell 103 abuts against the limit stopper 122, thereby clamping and positioning the battery cell 103 between the adhesive surface 105 and the side opposite the adhesive surface 105.

[0069] Specifically, the positioning mechanism 102 further includes a second base for supporting the support platform 121, the stopper 122, and the push assembly. Preferably, the push assembly further includes a push guide assembly, which includes a slide rail and a slider slidably mounted on the slide rail. The slide rail is horizontally mounted on the second base, and the slider is connected to the push member 123 to guide the movement of the push member 123.

[0070] In an optional solution of this embodiment, the positioning mechanism 102 further includes a pressing assembly; the pressing assembly includes a pressing member 125 and a seventh driving device 126. The seventh driving device 126 is used to drive the pressing member 125 to move closer to or away from the top surface of the battery cell 103 to apply pressure to the battery cell 103 and position it. Specifically, the pressing assembly is connected to the pushing member 123. When the pushing member 123 moves horizontally, the pressing assembly can move synchronously, so that the pressing member 125 can always be opposite to the middle of the large surface of the battery cell 103. The pressing member 125 and the supporting platform 121 can clamp and position the battery cell 103 from the top and bottom directions of the battery cell 103.

[0071] Preferably, the pressing assembly further includes a pressing guide assembly, which includes a slide rail and a slider slidably mounted on the slide rail. The slide rail is vertically mounted on the pusher 123 , and the slider is connected to the pressing member 125 to guide the movement of the pressing member 125 .

[0072] Optionally, at least the surface of the limit stop 122 in contact with the battery cell 103 is provided with an insulating layer; and / or at least the surface of the pushing member 123 in contact with the battery cell 103 is provided with a soft insulating layer; and / or at least the surface of the pressing member 125 in contact with the battery cell 103 is provided with a soft insulating layer.
