[0002] The battery pack of new energy vehicles needs good waterproof, dustproof and moisture-proof properties. The foamed silicone strip has excellent sealing performance, which can effectively prevent rain, dust, etc. from entering the battery pack, prevent battery short circuit, corrosion and other problems, and ensure that the battery pack can work stably in various harsh environments. For example, the Tesla Model 3 battery PACK uses a large amount of silicone foam potting materials.

[0003] In addition, the foamed silicone strips can act as buffer pads between battery packs and between batteries and battery pack shells to absorb the vibration and impact generated during vehicle driving, reduce friction and collision between batteries, avoid battery damage due to vibration, and extend the battery life.

[0004] In addition, the foamed silicone strips have good thermal insulation and flame retardant properties, which can prevent the transfer of heat inside the battery pack to a certain extent, prevent the battery from overheating, and reduce the risk of thermal runaway. In extreme cases of battery thermal runaway, they can also effectively resist high temperature invasion and ensure vehicle safety.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Embodiment 1: like Figures 1 to 12 As shown, a fully automatic foam silicone strip assembly double-head hot stamping machine includes: A processing table 1, two sets of hot stamping equipment 2, two sets of turning feeding equipment 3 and a rotating interlacing mechanism 4; The processing table 1 is arranged horizontally; The two groups of hot stamping equipment 2 are both installed on the processing table 1, and the two groups of hot stamping equipment 2 are arranged in a front-to-back staggered manner; The two groups of the flipping and feeding devices 3 are respectively arranged in one-to-one correspondence with the hot stamping devices 2, and the flipping and feeding devices 3 are clamped with the foamed silicone strips 00 and loaded into the corresponding hot stamping devices 2; The rotating interleaving mechanism 4 drives the two groups of the overturning and feeding devices 3 to be synchronously overturned, and the rotating interleaving mechanism 4 drives the two groups of the overturning and feeding devices 3 to overturn and feed in an interleaved manner.

[0027] It should be noted that compared with the existing foam silicone strip splicing processing equipment, the operator of the present invention only needs to repeatedly install the foam silicone strip 00 on the flip feeding equipment 3, and remove the foam silicone strip 00 that has completed the splicing processing on the flip feeding equipment 3. The operator does not need to touch the hot stamping equipment. The entire processing operation process is very safe and reliable, and the degree of automation is high. The operator does not need to perform large-scale processing actions.

[0028] like Figure 3 As shown, specifically, the hot stamping equipment 2 includes a mounting frame 21, a hot stamping seat 22, a hot stamping head 23, a lifter 24 and an electric control box 25; The mounting frame 21 includes a horizontal platform 211 and a vertical column 212; The hot stamping seat 22 is fixedly arranged on the platform 211, and a positioning groove 220 for carrying and positioning the foamed silicone strip 00 is opened on the hot stamping seat 22, and the splicing port 001 of the foamed silicone strip 00 is located in the positioning groove 220; The hot stamping head 23 is installed on the column 212 through the lifter 24. The lifter 24 drives the hot stamping head 23 to move toward the hot stamping seat 22. An electric heating element is arranged inside the hot stamping head 23. The lifter 24 is preferably a cylinder. The lifter 24 cooperates with the slide seat and the lifting screw group so that the lifter 24 can be lifted and lowered in the vertical direction. The electric control box 25 is installed on one side of the column 212 , and the electric control box 25 controls the heating of the hot stamping head 23 and the operation of the lifter 24 .

[0029] After the foam silicone strip 00 is installed in the positioning groove 220, the lifter 24 drives the hot stamping head 23 to descend and cooperate with the hot stamping seat 22 to perform bonding and heating processing on the foam silicone strip 00, so that the splicing end of the foam silicone strip 00 is spliced. After the splicing is completed, the lifter 24 drives the hot stamping head 23 to lift and reset, remove the foam silicone strip 00, and install a new foam silicone strip 00.

[0030] like Figures 5 to 11 As shown, the foamed silicone strip 00 is loaded by the overturning feeding device 3. Specifically, the overturning feeding device 3 includes two groups of symmetrically arranged overturning material racks 31. The spacing L between the two groups of the overturning material racks 31 and the width D of the hot stamping seat 22 satisfy the relationship: L>D. The overturning material rack 31 includes a rotating swing arm 311 and a material receiving seat 312. The rotating swing arm 311 is connected to the platform 211 for rotation and swinging. The material receiving seat 312 is arranged at the end of the rotating swing arm 311 for rotation and swinging. 2 is arranged in a U-shape, and a group of positioning pins 313 are arranged on the material receiving seat 312, which are positioned and interlaced with the holes 002 on the foamed silicone strip 00. When the foamed silicone strip 00 is installed, the holes 002 of the foamed silicone strip 00 are fitted onto the corresponding positioning pins 313, and the foamed silicone strip 00 is placed in the material receiving seat 312. It is worth emphasizing that the positioning pins 313 are arranged in a step-shaped shape, and the bottom diameter of the positioning pins 313 is slightly larger than the diameter of the holes 002, so that after the foamed silicone strip 00 is installed on the material receiving seat 312, the foamed silicone strip 00 is relatively stable.

[0031] Furthermore, a flip-up cover plate 315 is provided at the top of the opening of the material receiving seat 312, and a magnetic strip 3151 is provided on the cover plate 315, and the magnetic strip 3151 adsorbs and connects the cover plate 315 and the material receiving seat 312. The cover plate 315 can just cover the opening of the material receiving seat 312, so that the foamed silicone strip 00 can be just confined in the material receiving seat 312. At the same time, the flipping setting of the cover plate 315 can open the opening of the material receiving seat 312, so that the operator can quickly load the foamed silicone strip 00 onto the material receiving seat 312.

[0032] As a preferred embodiment, an elastically flipped first flip material plate 301 and a second flip material plate 302 are arranged between the two groups of flip material racks 31, and the first flip material plate 301 and the second flip material plate 302 are connected by a magnetic suction plate 303; The two sides of the hot stamping seat 22 are provided with protrusions 221 , which abut against the corresponding first flip material plate 301 and second flip material plate 302 to drive the first flip material plate 301 and the second flip material plate 302 to flip from a horizontal state to a vertical state.

[0033] It is worth mentioning that the bottom of the foamed silicone strip 00 can be supported by the first flip material plate 301 and the second flip material plate 302 between the flip material rack 31, ensuring that the splicing section 003 of the foamed silicone strip 00 can be in a good load-bearing state and is very stable. In addition, when the flip material rack 31 is flipped to the hot stamping seat 312 for loading, the first flip material plate 301 and the second flip material plate 302 can be flipped through the misalignment cooperation of the extrusion block 304 and the protrusion 221 set on the side, thereby opening the foamed silicone strip 00, allowing the hot stamping head 23 to descend, and completing the heating and bonding work.

[0034] It is further explained that metal spring sheets 305 are respectively provided at the rotating installation connection between the first flip material plate 301 and the flip material rack 31, and at the rotating installation connection between the second flip material plate 302 and the flip material rack 31. The first flip material plate 301 and the second flip material plate 302 that are flipped can be automatically reset by the metal spring sheets through the misaligned cooperation between the extrusion block and the protrusion 221.

[0035] like Fig.12 As shown, in order to achieve the purpose of alternately feeding the two groups of flip feeding devices 3, the rotating interlaced mechanism 4 includes a driving motor 41, a sensor 42, a foot switch 43 and a gear set 44; The driving motor 41 is installed on any of the overturning feeding devices 3, and the driving motor 41 drives the overturning material rack 31 to overturn, and the driving motor 41 is connected to the electric control box 25 by signal; The sensors 42 are provided in two groups, and the sensors 42 are provided in one-to-one correspondence with the overturning and feeding devices 3, and the sensors 42 sense the overturning and feeding devices 3 and output signals to the electric control box 25; The foot switch 43 is connected to the electric control box 25 by signal, and the foot switch 43 controls the forward and reverse rotation of the driving motor 41; The gear set 44 includes two sets of gears 441 meshing with each other. The gears 441 are respectively sleeved on the corresponding turning shafts 300 of the turning rack 31 .

[0036] Specifically, there are two groups of flipping feeding devices 3. One group feeds the foamed silicone strips 00 to the hot stamping seat 22, while the other group carries the foamed silicone strips 00 that have been bonded and flips them outward for output. The flipping feeding equipment 3 that has completed the output of the foamed silicone strips 00 is reloaded with new foamed silicone strips 00 to be bonded by the operator, and this is repeated.

[0037] It is further explained that, in the present invention, one set of driving motors 41 can drive two sets of flipping feeding devices 3 to perform alternating flipping operations. By coordinating the driving motors 41 with the gear set 44, the staggered flipping operations of the two sets of flipping feeding devices 3 are achieved.

[0038] It should be further noted that the sensor 42 senses that the hot stamping device 2 on the side of the flipping feeding device 3 is not working because the corresponding hot stamping device 2 is not equipped with the foamed silicone strip 00 at this time, and the hot stamping device 2 on the side of the flipping feeding device 3 is not sensed to be heated after the foamed silicone strip is installed through the control of the control board in the electrical control box 25.

[0039] The foot switch 43 is used by the operator to control the forward and reverse rotation of the drive motor 41. When the operator steps on the foot switch 43, the drive motor 41 receives the control signal from the electrical control box 25 and rotates forward, driving the flip feeding device 3 to switch. When the operator releases the foot switch 43, the drive motor 41 receives the control signal from the electrical control box 25 and reverses. The drive motor 41 of the present invention is preferably a servo motor.

[0040] Embodiment 2: The difference between Example 2 and Example 1 described in reference to Example 1 is that: like Figure 5 As shown, a suspended limiting plate 2111 is extended on one side of the platform 211 toward the operator, the suspended end of the limiting plate 2111 is raised in an arc shape, and the limiting plate 2111 limits the foamed silicone strip 00.

[0041] The purpose of setting the limiting plate 2111 is to prevent the rest of the foamed silicone strip 00 from shaking significantly when the foamed silicone strip 00 is flipped along with the flipping and feeding device 3. When the flipping and feeding device 3 drives the foamed silicone strip 00 to flip, the foamed silicone strip 00 located outside the flipping and feeding device 3 can be limited by the limiting plate 2111 and can be hooked by the limiting plate 2111, so there will be no problem of the foamed silicone strip 00 shaking randomly.

[0042] Embodiment 3: The differences between Example 3 and Example 1 described in reference to Example 1 are as follows: like Figure 13 to Figure 14 As shown, the material receiving seat 312 is extended with a material carrying plate 314 along the setting direction of the splicing section 003 of the foamed silicone strip 00, and the length S1 of the material carrying plate 314 and the length S2 of the corresponding splicing section 003 satisfy the relationship: ⅓S2<S1<½S2.

[0043] By adjusting the length of the carrier plate 314 , the foamed silicone strip 00 can be more stably supported on the carrier seat 312 . Therefore, the carrier seat 312 of the present invention is also extended with the carrier plate 314 , and the length of the carrier plate 314 is set.

[0044] Embodiment 4: The differences between Example 4 and Example 1 described in reference to Example 1 are as follows: like Figure 13 to Figure 14 As shown, the spacing T1 between the two groups of positioning pins 313 and the spacing T2 between the corresponding holes 002 satisfy the relationship: T2-0.10mm<T1<T2-0.05mm.

[0045] In order to ensure the stability of the foamed silicone strip 00 when it is flipped by the flipping feeding equipment, especially after the operator completes the glue coating and interface splicing at the interface, when the foamed silicone strip 00 is installed on the material receiving seat 312, the distance between the positioning pins 313 is adjusted to be slightly smaller than the distance between the holes 002, so as to achieve a pressure that is squeezed from both sides to the middle at the splicing port 001 of the foamed silicone strip 00, thereby improving the firmness of the splicing port 001 to squeeze the glue and improving the bonding effect.

[0046] Working process: Step 1: Gluing: the operator applies glue to the splicing ports of the foamed silicone strips, and then performs abutment splicing on the splicing ports to connect the splicing ports to each other; Step 2: Install the foamed silicone strip 00 onto the material receiving seat 312, and flip the cover plate 315 so that the cover plate 315 covers the opening of the material receiving seat 312, and the holes 002 on the foamed silicone strip 00 are inserted into the corresponding positioning pins 313; Step 3: Flip the material. The operator steps on the foot switch 43 to operate the drive motor 41, so that the material receiving seat 312 flips, so that the foamed silicone strip 00 is installed in the positioning groove 220 of the hot stamping seat 22. In this process, the first flip material plate 301 and the second flip material plate 302 are flipped through the misalignment of the extrusion block 304 and the protrusion 221, so that the foamed silicone strip 00 is exposed; Step 4: Heating. The lifter 24 drives the hot stamping head 23 to descend. The hot stamping head 23 contacts the hot stamping seat 22. The electric heating element in the hot stamping head 23 is powered on to heat up. The hot stamping head 23 begins to transfer the temperature to the foamed silicone strip 00, so that the glue at the splicing port 001 works faster, and the splicing port 001 of the foamed silicone strip 00 is bonded faster. Step five, alternating, synchronous with step one four, the working process of another group of flip feeding equipment 3 is just opposite to the action of the above-mentioned flip feeding equipment 3. The other group of flip feeding equipment 3 first takes the completed foamed silicone strip 00 away from the hot stamping seat 22, and then the operator removes the completed foamed silicone strip 00, and installs a new foamed silicone strip 00 to be bonded, waiting for a new cycle to repeat the work.

[0047] 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 in the protection scope of the present invention.
