Description

Technical Field

[0001] This invention relates to the technical field of high-performance foamed silicone strip bonding equipment for new energy batteries, and particularly to a high-performance foamed silicone strip bonding equipment for new energy battery packs. Background Technology

[0002] Currently, the filler for new energy batteries is expanded silicone foam. The function of expanded silicone foam is to fill the inside of the new energy battery. When the new energy battery heats up, it will expand to a certain extent. The expanded silicone foam is used to protect the battery from damage caused by the expansion. Expanded silicone foam also plays a role in fixing the battery block, so that the battery will not shake during use in the car. Expanded silicone foam also helps the new energy battery maintain a suitable temperature to achieve its optimal performance, improves the operating temperature, and dissipates excess heat through the battery shell. Each battery module requires hundreds of pieces of thermally conductive expanded silicone foam and filling silicone foam.

[0003] The existing foamed silicone strips used in new energy batteries require the foamed silicone strip to be laminated with an adhesive tape backing paper during the manufacturing process. The adhesive tape backing paper enables the foamed silicone strip to have adhesive properties, making it suitable for more working conditions, especially for the new energy battery field. After completing the lamination of the tape backing paper, the two ends of the foamed silicone strip need to be cut to form splicing ports. Then, glue is applied to the side wall of the splicing port to connect the two ends of the foamed silicone strip to form a silicone ring for use. The cutting, gluing, and connection of the existing foamed silicone strips are all done manually, which is slow and has a high error rate. Summary of the Invention

[0004] To address the above problems, this invention provides a high-performance foamed silicone strip bonding device for new energy battery packs. The device limits the two ends of the silicone strip and uses limiting blocks to position the ends. Then, a cutter automatically cuts the splicing ends of the silicone strip to form splicing ports. With the addition of an adhesive chamber inside the limiting blocks, adhesive is sprayed onto the splicing ports, automatically completing the splicing process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-performance foamed silicone strip bonding device for new energy battery packs includes:

[0007] Base, limit block and cutter;

[0008] The base is horizontally positioned, and a positioning groove is provided on the upper surface of the base for positioning silicone strips.

[0009] The limiting block is lifted and installed directly above the positioning material trough. The limiting block has a hollow interior with an adhesive chamber. The adhesive chamber is connected to an external adhesive supply device through a pipe. The limiting block has an adhesive spray hole on its side wall.

[0010] The cutter is mounted on the limiting block. The cutter includes a set of male cutters and a set of female cutters. The male cutters and the female cutters are respectively located on both sides of the limiting block. The male cutters and the female cutters descend with the limiting block to cut the splicing ends of the silicone strip in the positioning groove, forming wavy positive splicing ports and negative splicing ports on the silicone strip.

[0011] As an improvement, both the male blade and the female blade are provided with an exhaust port and a stripping groove. The stripping groove is provided on the side wall of the male blade and the female blade facing each other, and the limiting block is provided with a stripping column that is inserted into the stripping groove.

[0012] As an improvement, a fan is mounted on the upper surface of the base, and the fan is positioned directly opposite the limiting block.

[0013] As an improvement, both the limiting block and the cutter are raised and lowered by a lifting device. After the limiting block is inserted into the positioning groove, the cutter descends to cut the silicone strip.

[0014] As an improvement, the lifting device is connected to the cutter, the limiting block is suspended at the lifting end of the lifting device, and an adjusting spring is provided between the cutter and the limiting block, so that the cutter is offset relative to the limiting block.

[0015] As an improvement, the cutter has raised bumps evenly distributed on the sidewalls where it cuts the silicone strip. These bumps provide a roughening effect on the positive and negative splicing ports of the silicone strip.

[0016] As an improvement, both the male blade and the female blade include a blade holder, a cutting blade, a gear, and a rack;

[0017] The tool holder is horizontally positioned.

[0018] Several of the cutting blades are rotatably mounted on the blade holder in a semi-circular configuration. The side edges of the cutting blades are all blade-shaped, and the cutting blades are spliced ​​together to form a wavy cutting edge.

[0019] The gear is arranged in a ring shape on the top of the cutting blade;

[0020] The rack is slidably mounted on the blade holder. The rack reciprocates and engages with the gear, driving the cutting blade to rotate.

[0021] As an improvement, the protrusions are evenly distributed on both sides of the cutting blade, the protrusions are sharply positioned, and the protrusions rotate synchronously with the cutting blade.

[0022] As an improvement, hemispherical guide portions are provided at both ends of the rack, and wavy sliding guide portions are provided on the sidewalls of the limiting block and the cutter that are offset relative to each other, and the sliding guide portions are abutted against the guide portions.

[0023] As an improvement, the base is provided with a splicing mechanism that drives the cut silicone strips to be spliced ​​along the positioning groove. The splicing mechanism includes a clamping block and a pusher.

[0024] The clamping blocks are symmetrically installed on both sides of the positioning groove;

[0025] The pusher is installed in a one-to-one correspondence with the clamping block. The pusher drives the clamping block to push the silicone strip at an angle, clamping the silicone strip for pushing.

[0026] The beneficial effects of this invention are as follows:

[0027] (1) The present invention limits the two ends of the silicone strip and uses the limiting block to position the ends of the silicone strip. Then, the cutter automatically cuts the splicing ends of the silicone strip to form a splicing port. With the setting of the glue chamber inside the limiting block, glue is sprayed directly onto the splicing port to automatically complete the splicing work, so that the silicone strip can automatically complete the splicing work.

[0028] (2) The present invention provides a waste cavity inside the cutter to accommodate waste material, so that when the cutter cuts the silicone strip, the waste material of the silicone strip enters the waste cavity inside the cutter. Then, as the cutter resets, the waste material is discharged from the waste cavity through the cooperation of the discharge groove and the discharge column on the limit block, thus completing the discharge of waste material and automatic separation from the splicing position.

[0029] (3) The cutter of the present invention is formed by combining the cutting blades to form a female blade and a male blade, which are used to cut and form the positive splicing port and the negative splicing port so that they can be spliced ​​together. Furthermore, the cutting blades are improved so that they can rotate and swing independently. With the help of the protrusions on the cutting blades, the side walls of the positive splicing port and the negative splicing port are roughened by friction, which improves the retention and adsorption of glue on the side walls. At the same time, the roughness of the side walls improves the firmness of the splicing part.

[0030] (4) By setting up a splicing mechanism, the present invention uses the splicing mechanism to clamp the positive splicing port and the negative splicing port of the silicone strip and move them towards each other to achieve the purpose of automatic splicing. Furthermore, due to the clamping of the splicing mechanism, both the positive splicing port and the negative splicing port will expand to a certain extent. Whether in the glue spraying process or the splicing process, the expanded splicing port will be more conducive to the work.

[0031] In summary, this invention has the advantages of good stability of the splicing parts, strong splicing, and simple operation, and is especially suitable for the field of preparation technology of high-performance foamed silicone strips. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] Example 1:

[0053] like Figures 1 to 6 As shown, a high-performance foamed silicone strip bonding device for new energy battery packs includes:

[0054] Base 1, limiting block 2, and cutter 3;

[0055] The base 1 is horizontally arranged, and a positioning groove 11 is provided on the upper surface of the base 1. The positioning groove 11 is used to position the silicone strip 10, and the positioning groove 11 is arranged in a straight line. However, the positioning groove in this application is not limited to a straight line and can be adapted and adjusted according to the shape of the silicone strip.

[0056] The limiting block 2 is lifted and installed directly above the positioning material trough 11. The limiting block 2 has a hollow interior with an adhesive chamber 21. The adhesive chamber 21 is connected to the external adhesive supply equipment through a pipe. The side wall of the limiting block 2 has an adhesive spray hole 22. When the silicone strip is installed, the two ends to be spliced ​​directly abut against the limiting block 2. Then it is cut by a cutter. After the cutting is completed, the adhesive chamber 21 inside the limiting block 2 sprays out adhesive to coat the silicone strip. After the adhesive is coated, the silicone strip is brought together for splicing.

[0057] The cutter 3 is mounted on the limiting block 2. The cutter 3 includes a set of male cutters 31 and a set of female cutters 32. The male cutters 31 and the female cutters 32 are respectively disposed on both sides of the limiting block 2. The male cutters 31 and the female cutters 32 descend with the limiting block 2 to cut the splicing end of the silicone strip 10 in the positioning groove 11, forming a wavy positive splicing port 101 and a negative splicing port 102 on the silicone strip 10. The male cutter 31 cuts to form the positive splicing port 101, and the female cutter 32 cuts to form the negative splicing port 102. The positive splicing port 101 and the negative splicing port 102 are just connected and spliced. It should be emphasized that the shape of the positive splicing port 101 and the negative splicing port 102 is not limited to wavy shape, but can also be serrated or other shapes.

[0058] The male blade 31 and the female blade 32 are each provided with an exhaust port 311 and a stripping groove 312. The stripping groove 312 is provided on the side wall facing the male blade 31 and the female blade 32. The limiting block 2 is provided with a stripping column 23 that is inserted into the stripping groove 312.

[0059] Inside the cutter 3 is a waste chamber 30. After the male blade 31 or female blade 32 completes the cutting, the cut silicone strip waste directly enters the waste chamber 30. During the resetting process of the cutter 3, the silicone strip waste in the waste chamber 30 is discharged from the waste chamber 30 by the movement of the stripping column 23, which has been inserted into the waste chamber 30, in the stripping groove 312. Then, the silicone strip waste is blown and transferred by the fan 12. The fan 12 is installed on the upper surface of the base 1 and is positioned directly opposite the limiting block 2.

[0060] Example 2:

[0061] A preferred embodiment of Embodiment 2 of the present invention is described with reference to Embodiment 1:

[0062] like Figures 7 to 13 As shown, both the limiting block 2 and the cutter 3 are driven by the lifting device 4 to be raised and lowered. After the limiting block 2 is inserted into the positioning material groove 11, the cutter 3 descends to cut the silicone strip 10.

[0063] The lifting device 4 is connected to the cutter 3. The limiting block 2 is suspended at the lifting end of the lifting device 4. An adjusting spring 41 is provided between the cutter 3 and the limiting block 2, so that the cutter 3 is offset relative to the limiting block 2.

[0064] The cutter 3 has raised protrusions 33 evenly distributed on the side wall where it cuts the silicone strip 10. These protrusions 33 roughen the positive splicing port 101 and negative splicing port 102 on the silicone strip 10 through friction.

[0065] It should be noted that both the limit block 2 and the cutter 3 are raised and lowered by the lifting device 4, which is preferably a cylinder. The lifting device 4 drives the limit block 2 and the cutter 3 to descend synchronously. After the limit block 2 is inserted into the positioning groove 11, the limit switch at the positioning groove 11 will control the lifting device 4, and the lifting device 4 will stop working. After the silicone strip is installed in place, the lifting device 4 will be pneumatically activated again to drive the cutter 3 to descend. At this time, the adjusting spring 41 between the cutter 3 and the limit block 2 is compressed, so that the cutter 3 is inserted into the positioning groove 11 to cut the silicone strip, thus achieving effective connection between the actions of the cutter 3 and the limit block 2.

[0066] Example 3:

[0067] A preferred embodiment of Embodiment 3 of the present invention is described with reference to Embodiments 1 and 2:

[0068] like Figures 14 to 16 As shown, both the male blade 31 and the female blade 32 include a blade holder 321, a cutting blade 322, a gear 323, and a rack 324;

[0069] The blade holder 321 is horizontally arranged and is located inside the cutter 3;

[0070] Several of the cutting blades 322 are rotatably mounted on the blade holder 321 in a semi-circular arrangement. The side edges of the cutting blades 322 are all set with blade edges, and the cutting blades 322 are spliced ​​together to form a wavy cutting blade.

[0071] The gear 323 is arranged in a ring shape on the top of the cutting blade 322;

[0072] The rack 324 is slidably disposed on the blade holder 321. The rack 324 reciprocates and cooperates with the gear 323, driving the cutting blade 322 to rotate.

[0073] The protrusions 33 are evenly distributed on both sides of the cutting blade 322. The protrusions 33 are sharp and rotate synchronously with the cutting blade 322.

[0074] The rack 324 has hemispherical guide portions 325 at both ends, and the limiting block 2 and the cutter 3 have wavy sliding guide portions 24 on their side walls that are offset relative to each other. The sliding guide portions 24 are abutted against the guide portions 325.

[0075] It should be noted that when the silicone strip is cut by the cutter 3, as the cutter 3 moves with the limit block 2, the rack 324 moves horizontally through the contact between the guide part 325 and the arc guide part 24. In conjunction with the gear 323, each cutter blade 322 rotates and swings back and forth at a certain angle, causing the protrusions 33 to rub and roughen the side walls of the positive splicing port 101 and the negative splicing port 102, making the side walls change from smooth surfaces to rough surfaces, forming an uneven state. When the adhesive is applied, it can better retain the adhesive. Furthermore, during splicing, due to the roughness of the side walls, after the adhesive is connected, the protrusions on the side walls will intersect, forming a strong connection effect and ensuring the connection strength at the splicing position.

[0076] Example 4:

[0077] A preferred embodiment of Embodiment 4 of the present invention is described with reference to Embodiments 1, 2, and 3:

[0078] like Figure 17 As shown, the base 1 is provided with a splicing mechanism 5 that drives the cut silicone strips 10 to be spliced ​​along the positioning groove 11. The splicing mechanism 5 includes a clamping block 51 and a pusher 52.

[0079] The clamping blocks 51 are symmetrically installed on both sides of the positioning groove 11. There is a very small gap between the clamping blocks 51 and the silicone strip 10 in the positioning groove 11. The clamping blocks 51 clamp the silicone strip 10 through the pusher 52.

[0080] The pusher 52 and the clamping block 51 are installed in a one-to-one correspondence. The pusher 52 drives the clamping block 51 to push the silicone strip 10 at an angle, clamping the silicone strip 10 for pushing. The pushing end of the pusher 52 is hinged to the clamping block 51, and the other end of the pusher 52 is hinged to the base 1.

[0081] It should be noted that after the silicone strips are cut and coated with adhesive, they need to be spliced ​​together. During the splicing process, the silicone strips are clamped by the clamping block 51 and then pushed by the pusher 52 to splice the silicone strips together, thus achieving the purpose of automatic splicing.

[0082] It is important to note that after the silicone strip is cut and before the adhesive is applied, the pusher 52 will drive the clamping blocks 51 at both ends to clamp the silicone strip 10. Since the silicone strip itself has certain deformation characteristics, after the clamping blocks 51 clamp the silicone strip, both the positive splicing port 101 and the negative splicing port 102 will expand to a certain extent because the clamping blocks are close to the splicing ends of the silicone strip. This causes both the splicing port 101 and the negative splicing port 102 to open to a certain extent. At this time, when the adhesive is applied, the adhesive can be better retained on the side wall, and the splicing will be easier in the subsequent connection and splicing.

[0083] In addition, once the silicone strips are spliced, the pusher 52 will drive the clamp 51 to reset, and the silicone strips will automatically return to their previous deformation, thus achieving a perfect splicing of the silicone strip splicing parts without large and obvious splicing seams.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
