DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The embodiment of the present application provides a battery cell gluing device and a battery production line, which can completely cover the four corners of the bottom surface of the battery cell, solving the technical problems in the related art of manually wrapping the corners of the battery cell, resulting in poor sealing at the corners of the battery cell, uneven product quality, and low coating efficiency.

[0041] like Figure 1 As shown, an embodiment of the present application provides a battery cell gluing device, which may include: a first shaping block 1, a first rectangular shaping hole 12 is provided on the first shaping block 1, the corners of the hole wall of the first rectangular shaping hole 12 are chamfered, and the cross-section of the first rectangular shaping hole 12 gradually decreases from one end to the other end of the first rectangular shaping hole 12, and the cross-sectional area of ​​the end with the smallest inner diameter of the first rectangular shaping hole 12 is equal to the cross-sectional area of ​​the end of the battery cell 7 for gluing; the first rectangular shaping hole 12 allows the battery cell 7 to pass through the first rectangular shaping hole 12 from the end thereof for gluing. Exemplarily, the first rectangular shaping hole 12 is provided on the rear side of the first shaping block 1, and the four sides of the first rectangular shaping hole 12 are chamfered, and the cross-sectional area of ​​the first rectangular shaping hole 12 gradually decreases toward the front side, forming a rectangular trumpet-shaped structure.

[0042] Specifically, one end of the battery cell 7 with glue (referring to the end of the bottom surface of the battery cell 7 covered with the insulating tape 8) is moved from the rear end of the first rectangular shaping hole 12 (the rear end of the first rectangular shaping hole 12 is the end with a larger cross section of the first rectangular shaping hole 12) and passes through the front end of the first rectangular shaping hole 12. During the movement of the battery cell 7, the cross section of the first rectangular shaping hole 12 gradually decreases from the rear end to the front end of the first rectangular shaping hole 12, so that the insulating tape 8 can slowly cover the entire corner of the battery cell 7. Moreover, since the corners of the hole wall of the first rectangular shaping hole 12 are rounded, the problem of the insulating tape 8 being squeezed and damaged by the edges of the first rectangular shaping hole 12 can be improved. The problem that the corners of the battery cell are wrapped by hand in the related technology, resulting in poor sealing of the corners of the battery cell, uneven product quality, and low wrapping efficiency is solved.

[0043] It should be noted that, in the present application, “the cross-sectional area of ​​the end with the smallest inner diameter of the first rectangular shaping hole 12 is equal to the cross-sectional area of ​​one end of the battery cell 7 where the glue is attached” means that the cross-sectional area of ​​the end with the smallest inner diameter of the first rectangular shaping hole 12 is slightly smaller than the cross-sectional area of ​​one end of the battery cell 7 where the glue is attached, so that the first rectangular shaping hole 12 allows the battery cell 7 to pass through the first rectangular shaping hole 12 starting from the end where the glue is attached.

[0044] Further, such as Figure 1As shown, a second shaping block 2 is fixed to one side of the first shaping block 1, and a second rectangular shaping hole 22 is provided in the second shaping block 2, and one end of the second rectangular shaping hole 22 is fitted and connected to the end of the first rectangular shaping hole 12 with the smallest inner diameter, and the cross-sectional area of ​​one end of the second rectangular shaping hole 22 is equal to the cross-sectional area of ​​the end of the first rectangular shaping hole 12 with the smallest inner diameter. Exemplarily, a second shaping block 2 is fixed to the front side of the first shaping block 1, and a second rectangular shaping hole 22 is provided on the rear side of the second shaping block 2, and the second rectangular shaping hole 22 is fitted and connected to the front end of the first rectangular shaping hole 12, and the cross-sectional area of ​​the second rectangular shaping hole 22 is equal to the cross-sectional area of ​​the front end of the first rectangular shaping hole 12.

[0045] Specifically, after one end of the battery cell 7 with glue passes through the rectangular trumpet mouth, it will continue to pass through the second rectangular shaping hole 22. The inner wall surface of the second rectangular shaping hole 22 is parallel to the side surface of the battery cell 7. The second rectangular shaping hole 22 will squeeze the insulating tape 8 after the battery cell 7 is gathered, so that the insulating tape 8 fits tightly to the side surface and large surface of the battery cell 7, thereby improving the wrapping effect of the insulating tape 8.

[0046] Further, such as Figure 2 and Figure 3 As shown, the battery cell gluing device may also include: a first workbench 3, along the direction from one end to the other end of the first rectangular shaping hole 12, the first workbench 3 is arranged on the side with a larger cross section of the first rectangular shaping hole 12, the first workbench 3 is fixed with two receiving strips 31, and the two receiving strips 31 are used to support and guide the movement of the battery cell 7; a first cylinder push block (not shown in the figure), one end of the first cylinder push block is arranged on the first workbench 3, and the other end acts on the battery cell 7; and the first cylinder push block can push one end of the battery cell 7 to move into the first rectangular shaping hole 12. Exemplarily, the first workbench 3 is arranged behind the first rectangular shaping hole 12, the first cylinder push block is installed on the first workbench 3, and is arranged behind the battery cell 7, and the telescopic direction of the first cylinder push block extends along the front-back direction. Among them, the first cylinder push block includes a driving cylinder actuator to drive the first cylinder push block to move, and its driving cylinder is installed with the first cylinder push block corresponding to the first workbench 3. The cylinder push block will not be explained in detail below.

[0047] Specifically, the first cylinder push block, pushed by the driving cylinder, approaches the top surface of the battery cell 7 (the top surface of the battery cell 7 is the surface on which the top cover plate of the battery cell 7 is set), and contacts and pushes the battery cell 7 to move forward on the two receiving strips 31 until one end of the battery cell 7 with glue is pushed slowly out of the first rectangular shaping hole 12 of the first shaping block 1 to perform corner coating work, replacing the manual driving method with high precision, high working efficiency and high yield rate.

[0048] Further, such as Figure 2 and Figure 3 As shown, the battery cell gluing device may further include: two second cylinder push blocks 33, the two second cylinder push blocks 33 are arranged on the first workbench 3, the extension directions of the two second cylinder push blocks 33 are opposite to each other, and the two second cylinder push blocks 33 are used to push one end of the battery cell 7 for gluing to be centered in the cross-sectional area of ​​the first rectangular shaping hole 12. Exemplarily, two second cylinder push blocks 33 are installed on the top of the first workbench 3, the two second cylinder push blocks 33 are spaced apart in the left-right direction, and the battery cell 7 is arranged between the two second cylinder push blocks 33, and the extension directions of the two second cylinder push blocks 33 are both in the left-right direction and opposite to each other.

[0049] Exemplarily, before the battery cell 7 is pushed and moved into the first rectangular shaping hole 12, the two second cylinder pushing blocks 33 can be driven to approach each other and contact and push the side of the battery cell 7 to center the battery cell 7, thereby ensuring that the center point of the bottom surface of the battery cell 7 coincides with the center point of the first rectangular shaping hole 12, thereby ensuring that in the subsequent process of the first cylinder pushing block pushing the battery cell 7 into the first rectangular shaping hole 12, the battery cell 7 is prevented from being squeezed and damaged, thereby causing a safety accident.

[0050] Further, such as Figure 2 and Figure 3 As shown, the battery cell glue sticking device may also include: a second workbench 4, the second workbench 4 is provided with two third cylinder push blocks 41; the first shaping block 1 includes: two first concave plate bodies 11, the two first concave plate bodies 11 correspond to the two third cylinder push blocks 41 one by one, and are fixed to the corresponding third cylinder push blocks 41 respectively; when the two third cylinder push blocks 41 push the two first concave plate bodies 11 to fit each other, the two first concave plate bodies 11 form a first rectangular shaping hole 12. Exemplarily, the first shaping block 1 can be equally divided into two first concave plate bodies 11 along the left-right direction, each first concave plate body 11 is fixed to a third cylinder push block 41, and the moving direction of the third cylinder push block 41 is the up-down direction.

[0051] Specifically, after the battery cell 7 is pushed and moved into the first rectangular shaping hole 12, a third cylinder pushing block 41 can be started to move upward, and the other third cylinder pushing block 41 can be started to move downward, so that the two third cylinder pushing blocks 41 move away from each other, and drive the two first concave plates 11 to move away from each other, so that after completing the corner wrapping work of one end of the battery cell 7, the first concave plate 11 can be immediately withdrawn to avoid affecting the subsequent process of putting the battery cell 7 into the aluminum shell 6.

[0052] Of course, in some embodiments, the first shaping block 1 can be equally divided into two first concave plate bodies 11 along the left and right directions, and the corresponding two third cylinder push blocks 41 are spaced apart along the left and right directions, and their telescopic directions are left and right directions, and are connected to the corresponding first shaping block 1.

[0053] Further, such as Figure 2 and Figure 3 As shown, the second shaping block 2 can similarly be equally divided into two second concave plate bodies 21 along the left-right direction, and each second concave plate body 21 is fixed with a third cylinder push block 41, so that the third cylinder push block 41 can synchronously push the two first concave plate bodies 11 and the two second concave plate bodies 21 to move up and down for fitting, thereby forming the first rectangular shaping hole 12 and the second rectangular shaping hole 22.

[0054] Further, such as Figure 2 and Figure 3 As shown, both ends of the third cylinder push block 41 are slidably mounted on the second workbench 4. Among them, the two ends of the third cylinder push block 41 are slidably mounted on the second workbench 4, which can improve the stability and reliability of the third cylinder push block 41 when moving, and prevent the third cylinder push block 41 from being greatly offset during the movement process, thereby affecting the formation of the first rectangular shaping hole 12.

[0055] Further, such as Figure 2 and Figure 3 As shown, the battery cell gluing device may also include: a third workbench 5, along the direction from one end to the other end of the first rectangular shaping hole 12, the third workbench 5 is arranged on the side with a smaller cross section of the first rectangular shaping hole 12, the third workbench 5 is provided with two fourth cylinder push blocks 51, the extension and contraction directions of the two fourth cylinder push blocks 51 are opposite to each other, and an aluminum shell 6 is arranged between the two fourth cylinder push blocks 51; along the direction from one end to the other end of the first rectangular shaping hole 12, the opening direction of the aluminum shell 6 is arranged in front of the first rectangular shaping hole 12, and the opening of the aluminum shell 6 faces the first rectangular shaping hole 12. Exemplarily, the third workbench 5 is arranged in front of the first shaping block 1, the top surface of the third workbench 5 is installed with two fourth cylinder push blocks 51, and the moving direction of the two fourth cylinder push blocks 51 is the left and right direction, and the aluminum shell 6 is arranged between the two fourth cylinder push blocks 51, and the opening of the aluminum shell 6 faces the first rectangular shaping hole 12.

[0056] Specifically, by driving the two fourth cylinder push blocks 51 to approach each other, the aluminum shell 6 can be pushed to be centered in the left and right directions, ensuring that the center point of the end face of the aluminum shell 6 coincides with the center point of the first rectangular shaping hole 12, thereby ensuring that the battery cell 7 can be moved into the aluminum shell 6 after the corner coating process for final assembly.

[0057] Furthermore, the material of the side of the fourth cylinder push block 51 facing the aluminum shell 6 includes anti-slip rubber material.

[0058] Further, such as Figure 2 and Figure 3 As shown, the battery cell gluing device may further include: two pads 52, the two pads 52 are fixed to the third workbench 5, and the two pads 52 are used to support the aluminum shell 6. Exemplarily, the third workbench 5 is fixed with two pads 52 in the front-to-back direction, and the two fourth cylinder push blocks 51 are located between the two pads 52, and the pads 52 can support the aluminum shell 6 to ensure the stability of the aluminum shell 6.

[0059] Furthermore, the material of the first shaping block 1 , the second shaping block 2 , the receiving strip 31 and / or the pad 52 includes smooth and wear-resistant engineering plastics, such as PEEK (polyetheretherketone), POM (polyoxymethylene), and the like.

[0060] Furthermore, one end of the battery cell 7 where the glue is applied is the bottom surface of the battery cell 7, and both ends of the bottom surface of the battery cell 7 are covered with a first insulating tape 81, and the first insulating tape 81 is provided with an integrally formed second insulating tape 82, and the second insulating tape 82 covers the side surface of the battery cell 7; along the spacing direction between the two large surfaces of the battery cell 7, both ends of the first insulating tape 81 and the second insulating tape 82 are provided with an integrally formed third insulating tape 83; the third insulating tape 83 on the first insulating tape 81 and the third insulating tape 83 on the second insulating tape 82 are also integrally formed; along the spacing direction between the two large surfaces of the battery cell 7, the third insulating tape 83 on the first insulating tape 81 is arranged beyond the bottom surface of the battery cell 7, and the third insulating tape 83 on the second insulating tape 82 is arranged beyond the side surface of the battery cell 7. Exemplarily, before the battery cell 7 is pushed and moved into the first rectangular shaping hole 12, an insulating tape 8 needs to be arranged on the bottom surface of the battery cell 7, and the first insulating tape 81 of the insulating tape 8 is covered on one end of the bottom surface of the battery cell 7, and the second insulating tape 82 of the insulating tape 8 is covered on the side surface of the battery cell 7. Along the spacing direction of the two large surfaces of the battery cell 7, the third insulating tape 83 is extended from both ends of the first insulating tape 81 and the second insulating tape 82. Through the subsequent pushing and moving process into the first rectangular shaping hole 12, the third insulating tape 83 will be covered on the large surface of the battery cell 7.

[0061] Furthermore, along the spacing direction between the two large surfaces of the battery cell 7, the width of the third insulating tape 83 on one side exceeding the bottom surface of the battery cell 7 is Xmm, wherein 3≤X≤10; the width of the third insulating tape 83 on one side exceeding the side surface of the battery cell 7 is Ymm, wherein 1≤Y≤5. In this way, the extrusion process into the shell will not cause the insulating tape 8 to adhere to the aluminum shell 6 when it is contracted, resulting in the formation of explosion points in the battery top cover welding process.

[0062] It should be noted that the battery cell of the present application is also coated with a mylar film on the surface of the battery cell before the first insulating tape 81, the second insulating tape 82 and the third insulating tape 83 are covered at both ends of the bottom surface of the battery cell 7. That is, the battery cell of the present application is first coated with a mylar film on the outer layer, and then the first insulating tape 81, the second insulating tape 82 and the third insulating tape 83 are covered at both ends of the bottom surface of the battery cell 7.

[0063] An embodiment of the present application provides a battery production line, which includes a battery cell gluing device as described in some of the above embodiments.

[0064] How this application works is:

[0065] The two second cylinder push blocks 33 are used to push one end of the battery cell 7 where the glue is applied to be centered within the cross-sectional area of ​​the first rectangular shaping hole 12; and the two fourth cylinder push blocks 51 are driven to approach each other, so as to push the aluminum shell 6 to be centered in the left-right direction, ensuring that the center point of the end face of the aluminum shell 6 coincides with the center point of the first rectangular shaping hole 12.

[0066] After the above preparations are made, the first cylinder push block, under the push of the driving cylinder, approaches the top surface of the battery cell 7 (the top surface of the battery cell 7 is the surface on which the top cover plate of the battery cell 7 is set), and contacts and pushes the battery cell 7 to move forward on the two receiving strips 31, until the end of the battery cell 7 with glue is pushed to slowly move out of the first rectangular shaping hole 12 of the first shaping block 1, and the corner coating work is performed. After the tape coating is completed. On the one hand, the two third cylinder push blocks 41 respectively drive the two first concave plate bodies 11 to separate from each other, and drive the two second concave plate bodies 21 to separate from each other; on the other hand, the first cylinder push block continues to push the battery cell 7 forward to complete the entry into the aluminum shell 6. In this way, the coating and shelling of the battery cell 7 are achieved.
