Detailed Implementation

[0033] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0034] See Figure 5 The illustrated encapsulation device is used for... Figure 1 , Figure 2 The product 100 to be coated is shown undergoing a coating process. Specifically, see [link to details]. Figure 3 , Figure 4As shown, the wrapping device is used to cover the sides and bottom of the product 100 to be wrapped with a film 200 attached to the upper part of the product 100. The wrapping device has a wrapping station 300, and the wrapping device performs the film 200 wrapping process on the product 100 to be wrapped located at the wrapping station 300. The wrapping device includes an air blowing mechanism 1 and a wrapping assembly 2. The air blowing mechanism 1 has an air blowing port 111, which faces downward and toward the wrapping station 300. The wrapping assembly 2 is disposed on one side of the wrapping station 300 along a first direction. The wrapping assembly 2 includes a first wrapping member 21 and a second wrapping member 22. The second wrapping member 22 is located below the first wrapping member 21. The first wrapping member 21 and the second wrapping member 22 can be disposed relatively away from or relatively close to the wrapping station 300 along the first direction, and the second wrapping member 22 can be disposed movable relative to the first wrapping member 21 along the first direction.

[0035] During the coating process, the air outlet 111 blows air downwards, causing the film 200 attached to the upper part of the product 100 to be coated to bend downwards. This drives the first coating component 21 and the second coating component 22 to move closer to the product 100 located at the coating station 300 along a first direction. During this process, the first coating component 21 and the second coating component 22 push the film 200 downwards. When the first coating component 21 abuts against the side of the product 100, the film 200 adheres to the side of the product 100. At this point, the second coating component 22 continues to move relative to the first coating component 21 along the first direction and continues to move closer to the product 100. The second coating component 22 causes the film 200 attached to the side of the product 100 to bend again and adhere to the bottom of the product 100. Throughout the entire coating process, the first coating component 21 and the second coating component 22 only need to move along the first direction to complete the coating of the film 200, which is simple to control.

[0036] In this embodiment, the first wrapping member 21 has a first bending portion 211 protruding from the wrapping station 300 along a first direction, and the second wrapping member 22 has a second bending portion 221 protruding from the wrapping station 300 along a first direction. Both the first bending portion 211 and the second bending portion 221 are used to bend the film 200. In this embodiment, the wrapping assembly 2 has a first mode and a second mode. In the first mode, see [link to documentation]. Figure 8 , Figure 9As shown, the first bending portion 211 and the second bending portion 221 are parallel along the first direction. When the film 200 bends downward under the action of the air blowing mechanism 1, the wrapping assembly 2 can maintain the first mode and synchronously drive the first wrapping member 21 and the second wrapping member 22, so that the first bending portion 211 and the second bending portion 221 move closer to the film 200 together. The film 200 is attached to the side of the product 100 to be wrapped under the push of the first bending portion 211 and the second bending portion 221. In some embodiments, when the wrapping assembly 2 is in the first mode, the first bending portion 211 is located along the first direction on the side of the second bending portion 221 near the wrapping station 300. After the film 200 bends downward under the action of the air blowing mechanism 1, the first wrapping member 21 and the second wrapping member 22 are still synchronously driven to move closer to the film 200. The film 200 is mainly bent downward under the action of the first bending portion 211 and attached to the side of the product 100 to be wrapped.

[0037] In some preferred embodiments, the upper part of the product to be wrapped 100 is provided with an attachment area for attaching the film 200. When the product to be wrapped 100 is located at the wrapping station 300, the top of the first bend 211 is higher than the attachment area, or the top of the first bend 211 is level with the attachment area, thus ensuring that the film 200 is firmly attached to the side of the product to be wrapped 100.

[0038] See Figures 10 to 13 As shown, in the second mode, the second bending portion 221 extends along the first direction to the side of the first bending portion 211 near the wrapping station 300. After the film 200 is attached to the side of the product 100 to be wrapped, the wrapping assembly 2 switches to the second mode. During this process, the first wrapping member 21 remains stationary relative to the product 100 to be wrapped, and the second bending portion 221 continues to move toward the product 100 to be wrapped. The second bending portion 221 drives the lower part of the film 200 to be bent a second time, so that the film 200 is attached to the bottom of the product 100 to be wrapped.

[0039] In this embodiment, the air blowing mechanism 1 includes an air blowing nozzle 11, which is located above the wrapping component 2, and the air blowing nozzle 11 has the aforementioned air blowing port 111.

[0040] In this embodiment, the coating device includes a movable base 3, which is movably disposed along a first direction. A first coating member 21 and a second coating member 22 are disposed on the movable base 3. By driving the movable base 3 to move along the first direction, the first coating member 21 and the second coating member 22 can be synchronously driven to move along the first direction. In this embodiment, the first coating member 21 is movably disposed relative to the movable base 3 along the first direction. The coating device includes a first elastic member 41, which is disposed between the movable base 3 and the first coating member 21. The first elastic member 41 provides the force required to prevent the first coating member 21 from moving away from the coating station 300 along the first direction. During the coating process, after the first coating component 21 comes into contact with the product 100 to be coated, the moving seat 3 continues to move towards the coating station 300. During this process, the first coating component 21 and the moving seat 3 move relative to each other, so that the first coating component 21 and the product 100 to be coated remain relatively stationary, while the second coating component 22 can continue to move relative to the product 100 to be coated. Specifically, the first elastic component 41 is a spring. The first elastic component 41 serves as a buffer to prevent damage to the product 100 to be coated when the first coating component 21 comes into contact with it. On the other hand, during the above process, the first elastic component 41 is compressed, which allows the first coating component 21 to remain in contact with the product 100 to be coated.

[0041] In this embodiment, the movable seat 3 includes a mounting part 31 and a sliding part 32. The coating device has a fixing frame 10. The sliding part 32 is slidably disposed on the fixing frame 10 along a first direction. The mounting part 31 is fixedly disposed on the upper part of the sliding part 32. The fixing frame 10 is also provided with a driving member 33 for driving the sliding part 32 to slide. See also Figure 5 , Figure 8 As shown, the first coating member 21 is slidably disposed on the upper part of the mounting part 31 along the first direction. Specifically, the fixing frame 10 is provided with a first guide rail extending along the first direction, the sliding part 32 is slidably disposed on the first guide rail, the mounting part 31 is provided with a second guide rail, and the first coating member 21 is slidably disposed on the second guide rail. The first guide rail provides guidance for the movement of the movable seat 3, and the second guide rail provides guidance for the movement of the first coating member 21. In this embodiment, the upper part of the mounting part 31 has an upwardly protruding boss 311. Along the first direction, the boss 311 is located on the side of the first coating member 21 away from the coating station 300, and the first elastic member 41 is disposed between the first coating member 21 and the boss 311.

[0042] In this embodiment, see Figure 8 , Figure 9As shown, the first coating component 21 includes a mounting base 212 and a bending head 213. The mounting base 212 is slidably mounted on a second guide rail, and the bending head 213 is mounted on the mounting base 212. The end of the bending head 213 near the coating station 300 along a first direction forms a first bending portion 211. In this embodiment, the bending head 213 is height-adjustably mounted on the mounting base 212, and a locking structure is provided between the bending head 213 and the mounting base 212 to lock them together. When the coating device is in operation, the locking structure is in a locked state.

[0043] In this embodiment, the second coating member 22 is rotatably mounted on the movable seat 3 about a rotation center line extending along a second direction perpendicular to the first direction. The second coating member 22 has a drive portion 222 located along the first direction away from the coating station 300, and the rotation center line is located between the second bending portion 221 and the drive portion 222 along the first direction. The coating device also includes a second elastic member 42 disposed between the drive portion 222 and the movable seat 3. The second elastic member 42 provides the force required to drive the drive portion 222 downward. According to the lever principle, under the force of the second elastic member 42, the second bending portion 221 maintains an upward tendency, thereby enabling the film 200 to be tightly attached to the bottom of the product 100 to be coated.

[0044] In this embodiment, see Figure 9 As shown, under the action of the second elastic member 42, the second bent part 221 always abuts against the first film member 21 upward.

[0045] Specifically, see Figure 9 , Figure 13 As shown, in this embodiment, the second coating member 22 includes a first extension 22a, a second extension 22b, and a third extension 22c. The first extension 22a extends along a first direction, the second extension 22b extends downward from the end of the first extension 22a away from the coating station 300, and the third extension 22c extends from the lower part of the second extension 22b along the first direction away from the coating station 300. The second extension 22b is rotatably connected to the mounting portion 31 about a rotation center line, and the third extension 22c is located below the mounting portion 31. The second elastic member 42 is disposed between the mounting portion 31 and the third extension 22c.

[0046] In this embodiment, the coating device can simultaneously coat multiple products 100 to be coated, resulting in higher work efficiency. Specifically, the coating device includes multiple wrapping components 2 spaced apart along a second direction, each of which is used to bend the film 200 on the multiple products 100 to be coated. The coating device also includes multiple air inlets 111 spaced apart along the second direction, each of which is used to drive the multiple films 200 downwards. In this embodiment, see [reference needed]. Figure 5 , Figure 6 As shown, the wrapping component 2 and the air inlet 111 are staggered along the second direction. This arrangement prevents the gas blown out of the air inlet 111 from colliding with the wrapping component 2 and changing its direction, thus affecting the surrounding gas and causing the surrounding gas flow to become disordered. This avoids affecting the effect of the air blowing mechanism 1 in bending the film 200.

[0047] In this embodiment, the coating device further includes a carrier 5 for carrying the product 100 to be coated; the carrier 5 is provided with a support surface 51 for supporting the product 100 to be coated, and the carrier 5 is also provided with a first limiting member 52, a clamping member 53, and a second limiting member 54. When the carrier 5 is located at the coating station 300, the first limiting member 52 and the clamping member 53 are respectively disposed on both sides of the support surface 51 along a second direction, and the second limiting member 54 is located on the side of the support surface 51 away from the wrapping assembly 2 along a first direction. The first limiting member 52 and the second limiting member 54 are fixedly disposed, and the clamping member 53 is movable along the second direction. The carrier 5 is also provided with a third elastic member 43, which is used to provide the force required to drive the clamping member 53 toward the support surface 51 along the second direction. See also Figure 5 As shown, a fixing space for fixing the product 100 to be wrapped is formed between the support surface 51, the first limiting member 52, the clamping member 53, and the second limiting member 54. With the cooperation of the first limiting member 52 and the clamping member 53, the product 100 to be wrapped can be clamped and fixed along the second direction. The second limiting member 54 can restrict the movement of the product 100 to be wrapped along the first direction. The carrier 5 has an opening communicating with the fixing space on the side of the wrapping assembly 2 along the first direction. At least part of the product 100 to be wrapped and the film 200 attached thereto extend out of the fixing space from the opening. When the wrapping assembly 2 abuts against the product 100 to be wrapped extending out of the fixing space, the product 100 to be wrapped is pressed against the second limiting member 54.

[0048] In this embodiment, the carrier 5 is further provided with an unlocking member 55, used to release the clamping member 53 from clamping the product 100 to be wrapped. The unlocking member 55 is movably disposed along a first direction, see [reference]. Figure 7As shown, the unlocking member 55 has a first driving surface 551, which is located away from the supporting surface 51 along a second direction and away from the clamping member 53 along a first direction. The clamping member 53 has a second driving surface 531, which is parallel to the first driving surface 551 and abuts against each other. By driving the unlocking member 55 to move towards the clamping member 53 along the first direction, the first driving surface 551 and the second driving surface 531 can be driven to slide relative to each other, thereby pushing the clamping member 53 away from the supporting surface 51.

[0049] Specifically, each unlocking member 55 has at least a first position and a second position. When the unlocking member 55 is in the first position, the clamping member 53 is close to the support surface 51 and can clamp the product 100 to be coated. When the unlocking member 55 is in the second position, the clamping member 53 moves away from the support surface 51 and releases the clamp on the product 100 to be coated. When the unlocking member 55 moves toward the clamping member 53 in a first direction, the unlocking member 55 moves from the first position to the second position. In this embodiment, a fourth elastic member 44 is provided between the unlocking member 55 and the carrier 5. The fourth elastic member 44 is used to drive the unlocking member 55 to move toward the first position, that is, the fourth elastic member 44 is used to drive the unlocking member 55 away from the clamping member 53, so that the clamping member 53 can maintain the clamping and fixing of the product 100 to be coated.

[0050] In this embodiment, the carrier 5 is provided with multiple support surfaces 51 along the second direction. Each support surface 51 has a first limiting member 52, a second limiting member 54, and a clamping member 53 on its periphery, thereby forming multiple fixing spaces along the second direction for fixing the product 100 to be wrapped. The carrier 5 is provided with multiple unlocking members 55 along the second direction, which are used to drive the clamping members 53 away from the support surfaces 51. The unlocking members 55 are provided with an operating part 552 for driving them to move along the first direction. When the carrier 5 is located at the wrapping station 300, see [reference needed]. Figure 10 , Figure 11 As shown, when all unlocking elements 55 are in the first position, or when all unlocking elements 55 are in the second position, the operating parts 552 of the multiple unlocking elements 55 are collinearly arranged along the second direction, thereby enabling the multiple unlocking elements 55 to be synchronously driven to switch between the first position and the second position. Specifically, the multiple unlocking elements 55 can be synchronously driven to move towards the second position, thereby synchronously releasing the clamping elements 53 from clamping the product to be coated 100.

[0051] In this embodiment, the product to be coated, 100, is a mobile phone battery.

[0052] In summary, during the coating process, the coating device of this embodiment uses the air blowing mechanism 1 to blow air downwards to bend the film 200 downwards. Then, it simply drives the first coating member 21 and the second coating member 22 towards the coating station 300 along the first direction, pushing the film 200 to continue bending downwards and attaching it to the side of the product 100 to be coated. Afterwards, the first coating member 21 remains stationary relative to the product 100 to be coated, while the second coating member 22 continues to move. The lower portion of the film 200 bends a second time under the push of the second coating member 22 and attaches to the bottom of the product 100 to be coated. The first coating member 21 and the second coating member 22 only need to perform a single linear movement, making control simple. Furthermore, simply driving the first coating member 21 and the second coating member 22 towards the product 100 to be coated at the coating station 300 along the first direction is sufficient to complete the coating of the film 200, thus improving the processing efficiency of the coating device.
