Description

Technical Field

[0001] This utility model relates to the field of battery coating technology, and in particular to a battery coating device. Background Technology

[0002] Batteries are an important component of electronic devices. Batteries are usually attached to the casing of electronic devices by adhesive tape (batteries are usually attached to the casing of electronic devices by adhesive layers. To avoid damage to the battery and casing when removing the battery, the tape is electrically connected to the adhesive layer. The tape can be used to separate the adhesive layer from the casing by passing electricity through the tape). The tape needs to be attached to the second surface of the battery, passing around the first end of the battery. The first surface and the second surface of the battery are the two surfaces of the battery in the thickness direction. The first end of the battery refers to the end of the battery located in its length or width direction.

[0003] To facilitate the installation of battery A and the arrangement of its electrodes, battery A has a stepped structure at its first end. Please refer to [reference needed]. Figure 1 The stepped structure in the middle has a first stepped surface A1, and the tape A3 needs to be pressed onto the first stepped surface A1 by the battery encapsulation device. Figure 1 This is a schematic diagram showing that tape A3 is not pressed onto the first step surface A1. Figure 2 This is a schematic diagram showing the tape A3 being pressed onto the first step surface A1. In related technologies, when the first pressing mechanism of the battery encapsulation device presses the tape A3 onto the first step surface A1, it is easy to damage the battery at the second step surface A2 of the stepped structure. Utility Model Content

[0004] This utility model discloses a battery coating device to solve the problem that battery coating devices in related technologies are prone to causing pressure damage to batteries during the coating process.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] This application discloses a battery coating device, which includes a frame, a battery fixing module, and a first pressing mechanism, wherein:

[0007] The battery fixing module is disposed on the frame. The battery fixing module has a support surface and a first side surface adjacent to and perpendicular to the support surface. The first pressing mechanism includes a first driving mechanism and a first pressing body. The first pressing body is opposite to and spaced apart from the first side surface. The first end of the first pressing body is opposite to the end of the battery fixing module where the support surface is located. The second end of the first pressing body is located on the side below the support surface. The distance between the first end of the first pressing body and the first side surface is less than the distance between the second end of the first pressing body and the first side surface. The first driving mechanism is disposed on the frame and connected to the first pressing body for driving the first pressing body to move along a first direction, wherein the first direction is perpendicular to the support surface.

[0008] The technical solution adopted in this utility model can achieve the following technical effects:

[0009] The battery encapsulation device disclosed in this application configures the first pressing body as a structure that is opposite to and spaced apart from the first side, and makes the second end of the first pressing body tilted away from the first side relative to the first end of the first pressing body. This makes it so that when the first driving mechanism drives the first pressing body to press the tape onto the first step surface, the distance between the first pressing body and the second step surface gradually increases in the direction from the first end of the first pressing body to the second end of the first pressing body. Therefore, it is only necessary to adjust the distance between the edge of the end face of the first end of the first pressing body and the second step surface of the battery to ensure that other parts of the first pressing body will not press on the second step surface, thereby avoiding the first pressing body from damaging the second step surface.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 7 This utility model discloses a battery coating device, which includes a frame 100, a battery fixing module 200 and a first pressing mechanism 300.

[0026] The frame 100 is the basic component of the battery encapsulation device, providing a base for mounting other components of the battery encapsulation device. The battery fixing module 200 is disposed on the frame 100. The battery fixing module 200 has a support surface 201 and a first side surface 202 adjacent to and perpendicular to the support surface 201. The support surface 201 is used to support and fix the battery A.

[0027] The first pressing mechanism 300 includes a first driving mechanism 310 and a first pressing body 320. The first pressing body 320 is opposite to and spaced apart from the first side surface 202. The first end of the first pressing body 320 is opposite to the end where the support surface 201 of the battery fixing module 200 is located. The end face of the first end of the first pressing body 320 is used to press the tape A3 onto the first stepped surface A1 (please refer to...). Figure 1 , Figure 2 and Figure 7 The second end of the first pressure film body 320 is located on the side below the support surface 201. The width of the end face of the first end of the first pressure film body 320 can be greater than or equal to 3.5 mm, thereby accommodating a larger range of widths for the first step surface A1.

[0028] The distance between the first end of the first pressing body 320 and the first side surface 202 is less than the distance between the second end of the first pressing body 320 and the first side surface 202, that is, the second end of the first pressing body 320 is inclined away from the first side surface 202 relative to the first end of the first pressing body 320 (please refer to...). Figure 5 The tilt angle α in the middle.

[0029] The first driving mechanism 310 is disposed on the frame 100 and is connected to the first pressing body 320. It is used to drive the first pressing body 320 to move along a first direction, wherein the first direction is perpendicular to the support surface 201.

[0030] Please refer to Figure 5 and Figure 7 When the battery encapsulation device is set up as shown in the figure, with battery A placed and fixed on support surface 201, the stepped structure of battery A extends out from the side of the first side surface 202. At this time, the first stepped surface A1 faces downward, and the first pressing body 320 is located below the first stepped surface A1, with the end face of the first end of the first pressing body 320 facing the first stepped surface A1. The first driving mechanism 310 can drive the first pressing body 320 to move upward in the first direction, so that the end face of the first end of the first pressing body 320 presses the tape A3 onto the first stepped surface A1. After the tape A3 is pressed onto the first stepped surface A1, the first driving mechanism 310 can drive the first pressing body 320 to move downward in the first direction, so that the end face of the first end of the first pressing body 320 separates from the first stepped surface A1.

[0031] It should be noted that, since the second end of the first pressing body 320 is inclined away from the first side surface 202 relative to the first end of the first pressing body 320, when the first driving mechanism 310 drives the first pressing body 320 to move upward in the first direction so that the end face of the first end of the first pressing body 320 presses the tape A3 onto the first stepped surface A1, the edge of the end face of the first end of the first pressing body 320 is closest to the second stepped surface A2 of the battery A (for example, the distance can be 0.5mm). In the direction from the first end to the second end of the first pressing body 320, the distance between the first pressing body 320 and the second stepped surface A2 gradually increases, thereby preventing the first pressing body 320 from damaging the second stepped surface A2. After the battery A is supported on the support surface 201, the first stepped surface A1 is parallel to the support surface 201, and the second stepped surface A2 is parallel to the first side surface 202.

[0032] The battery encapsulation device disclosed in this application configures the first pressing body 320 to be opposite to and spaced apart from the first side surface 202, and makes the second end of the first pressing body 320 tilted away from the first side surface 202 relative to the first end of the first pressing body 320. When the first driving mechanism 310 drives the first pressing body 320 to press the tape A3 onto the first step surface A1, the distance between the first pressing body 320 and the second step surface A2 gradually increases in the direction from the first end of the first pressing body 320 to the second end of the first pressing body 320. Therefore, by simply adjusting the distance between the edge of the end face of the first end of the first pressing body 320 and the second step surface A2 of the battery A, it can be ensured that other parts of the first pressing body 320 will not press on the second step surface A2, thereby avoiding the first pressing body 320 damaging the second step surface A2.

[0033] It should be noted that, in the related technology, after adjusting the distance between the edge of the first end face of the first pressing body and the second step surface A2 of the battery A, other parts of the first pressing body are prone to damage to the second step surface A2.

[0034] Optionally, the first pressing body 320 may include a main body 321 and a first buffer 322. The first buffer 322 may be disposed at the first end of the main body 321. The end where the first buffer 322 is located may be the first end of the first pressing body 320, and the second end of the main body 321 may be the second end of the first pressing body 320.

[0035] Specifically, the first buffer portion 322 can be a component with a certain degree of elasticity, and the hardness of the first buffer portion 322 can be greater than or equal to 80 Duro, and the hardness of the first buffer portion 322 can be less than or equal to 90 Duro. Of course, the hardness of the first buffer portion 322 can also be other hardnesses, for example, the hardness of the first buffer portion 322 can also be between 75 Duro and 80 Duro, etc.

[0036] The battery coating device disclosed in this application configures the first pressing body 320 to include a main body 321 and a first buffer part 322. When the first driving mechanism 310 drives the first pressing body 320 to press the tape A3 onto the first stepped surface A1, the first buffer part 322 contacts the first stepped surface A1, thus preventing scratches on the battery A. Furthermore, it avoids rigid contact between the first pressing body 320 and the battery A at the first stepped surface A1, thereby protecting the battery A. By setting the hardness of the first buffer part 322 to be greater than or equal to 80 Duro and less than or equal to 90 Duro, it avoids excessive hardness that could scratch the battery, and also avoids insufficient hardness that would result in poor pressing of the tape A3 onto the first stepped surface A1.

[0037] Since different batteries A may have different requirements for the hardness and size of the first buffer part 322 when pressing the tape A3, in order to adapt the battery coating device to different batteries A, the main body 321 and the first buffer part 322 can be detachably connected, so that the first buffer part 322 can be replaced as needed, thereby making the battery coating device adaptable to different batteries.

[0038] The main body 321 and the first buffer part 322 can be connected by means of snaps or bolts.

[0039] To facilitate the installation and disassembly of the main body 321 and the first buffer part 322, optionally, the end face of the first end of the main body 321 may have multiple first protrusions 321a, the first buffer part 322 may have multiple mounting grooves, the bottom of the mounting groove to the opening of the mounting groove may be constricted, the shape of the first protrusions 321a may be adapted to the shape of the mounting groove, and the multiple first protrusions 321a may be correspondingly embedded in the multiple mounting grooves.

[0040] Since the first buffer part 322 is a component with a certain degree of elasticity, by setting the end face of the first end of the main body part 321 to have a structure with multiple first protrusions 321a, and by setting multiple mounting grooves in the first buffer part 322, it can be installed in the mounting groove by means of the elastic characteristics of the first protrusions 321a. Thus, the main body part 321 and the first buffer part 322 can be disassembled and installed by external force, thereby making the installation and disassembly of the main body part 321 and the first buffer part 322 more convenient.

[0041] To better protect battery A, the battery fixing module 200 may optionally include a fixing body 210 and a second buffer part 220. The fixing body 210 may be disposed on the frame 100, and the second buffer part 220 may be disposed on the fixing body 210. The second buffer part 220 may have a support surface 201. The second buffer part 220 may be a component with a certain degree of elasticity, and the hardness of the second buffer part 220 may be referenced to the hardness of the first buffer part 322.

[0042] The battery coating device disclosed in this application sets the battery fixing module 200 to include a fixing body 210 and a second buffer part 220, so that the battery A is supported by the second buffer part 220, thereby avoiding rigid contact between the battery A and the battery fixing module 200, and thus better protecting the battery A.

[0043] Battery A can be fixed to the support surface 201 using clips, double-sided tape, or other components.

[0044] To make it easier to fix battery A, the fixing body 210 may optionally have a suction cup 211, and the second buffer part 220 may have a first clearance hole 221. The suction cup 211 may be located in the first clearance hole 221 and may be used to adsorb battery A onto the support surface 201.

[0045] The battery coating device disclosed in this application uses a suction cup 211 to adsorb the battery A onto the support surface 201. Thus, the battery A can be fixed simply by controlling the suction of the suction cup 211, making the fixing of the battery A more convenient.

[0046] When battery A is placed on support surface 201, it needs to be positioned so that, when battery A is placed and fixed to support surface 201, the distance by which the stepped structure of battery A extends beyond the first side surface 202 is relatively accurate. This ensures the distance between the edge of the first end face of the first pressure film body 320 and the second stepped surface A2 of battery A. Optionally, for positioning battery A, fixing body 210 has a positioning post 212, and the second buffer portion 220 has a second clearance hole. The positioning post 212 extends through the second clearance hole to above the support surface 201, and the positioning post 212 is used to position the battery.

[0047] It should be noted that battery A may be fitted with an iris layer, which has an ear C extending out of battery A. The ear C has a positioning hole. When battery A is placed on the support surface 201, the positioning hole of the ear C fits into the positioning post 212, thereby positioning battery A. The clearance between the positioning hole and the positioning post 212 can be 0.1mm. Alternatively, the positioning post 212 can directly contact the side wall of battery A for positioning. This embodiment does not specifically limit the positioning method of battery A by the positioning post 212.

[0048] Optionally, the battery encapsulation device may further include a second pressing mechanism 400. The second pressing mechanism 400 may include a second driving mechanism 410 and a second pressing body 420. The second driving mechanism 410 may be disposed on the frame 100, and the second pressing body 420 may be connected to the second driving mechanism 410. The second pressing body 420 may be distributed relative to the first pressing body 320 in a first direction, and the second pressing body 420 may be located on the side above the support surface 201. The second driving mechanism 410 is used to drive the second pressing body 420 to move along the first direction so that the second pressing body 420 can press the portion of the tape A3 away from the first step surface A1 onto the battery A.

[0049] Furthermore, the second pressing body 420 may have a third buffer portion 421, which may be opposite to the first pressing body 320. The third buffer portion 421 may be a component with a certain elasticity, and the hardness of the third buffer portion 421 may be referenced to the hardness of the first buffer portion 322.

[0050] The battery encapsulation device disclosed in this application configures the second pressing body 420 with a third buffer part 421, so that the second pressing body 420 contacts the battery A through the third buffer part 421, thereby avoiding rigid contact between the third buffer part 421 and the battery A, and thus protecting the battery A.

[0051] The second pressing body 420 and the first pressing body 320 can simultaneously press the tape A3 from opposite sides of the stepped structure. This not only saves time in pressing the tape A3, but also allows the second pressing body 420 and the first pressing body 320 to support the battery A from both sides, thereby protecting the battery.

[0052] Optionally, the tilt angle of the second end of the first pressing body 320 relative to the first end of the first pressing body 320 toward the side away from the first side 202 can be greater than or equal to 5 degrees and less than or equal to 15 degrees.

[0053] Specifically, the first buffer part 322, the second buffer part 220 and the third buffer part 421 can all be thermoplastic polyurethane elastomer rubber.

[0054] by Figure 3 Taking the battery coating device shown as an example, the process of coating battery A is explained. First, battery A is placed on the support surface 201 of the battery fixing module 200. The positioning post 212 positions battery A so that the stepped structure of battery A extends out of the first side 202 on the side where the first side 202 is located, with the first stepped surface A1 facing downward. Then, the suction cup 211 is used to adsorb battery A onto the support surface 201, so that battery A is fixed on the support surface 201. Then, the first driving mechanism 310 drives the first pressing body 320 to move upward in the first direction, so that the end face of the first end of the first pressing body 320 presses the tape A3 onto the first stepped surface A1. The second driving mechanism 410 drives the second pressing body 420 to move downward in the first direction, so that the second pressing body 420 presses the part of the tape A3 away from the first stepped surface A1 onto battery A. After the first pressing body 320 and the second pressing body 420 have pressed the tape A3, the first driving mechanism 310 drives the first pressing body 320 to move downward in the first direction so that the end face of the first end of the first pressing body 320 is separated from the first step surface A1. The second driving mechanism 410 drives the second pressing body 420 to move upward in the first direction so that the second pressing body 420 is separated from the side of the tape A3 that is away from the first step surface A1. After that, the suction cup 211 stops adsorbing the battery A, and the battery can be removed for subsequent processes.

[0055] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0056] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
