DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] See also Figures 1 to 8 The coating machine 10 provided by an embodiment of the present invention is applied to the coating field of a charger 100. The charger 100 has a plurality of circumferential side surfaces and front and rear end surfaces. The front and rear end surfaces refer to the two surfaces on which the pins and the connection terminals are provided. The coating machine 10 is used to assist in attaching the protective film 200 to the side and end surfaces of the charger 100. Specifically, the charger 100 is roughly square, and has four side surfaces and two end surfaces.

[0029] The coating machine 10 includes a body 12, a supporting mechanism and a coating machine 10 mechanism, wherein the supporting mechanism and the coating machine 10 mechanism are respectively arranged on the body 12, wherein the supporting mechanism is used to support the protective film 200 and the charger 100, and the coating machine 10 mechanism is used to assist in attaching the protective film 200 to the charger 100.

[0030] The supporting mechanism includes two protective film support seats 14 and a charger support seat 16. The two protective film support seats 14 are arranged opposite to each other and are used to support the two ends of the protective film 200. The charger support seat 16 is located between the two protective film support seats 14 and is used to support the charger 100. The charger support seat 16 and the two protective film support seats 14 can cooperate to form a storage space 18 for accommodating the charger 100. The storage space 18 is located between the two protective film support seats 14. During the film coating process, the protective film 200 can be placed on the two protective film support seats 14 first, and then the charger 100 is aligned with the charger support seat 16 and placed on the protective film 200. During the process of the charger 100 entering the storage space 18, the protective film 200 is deformed under the action of the charger 100, and the two ends of the protective film 200 are changed from a flat state to an upright state. When the charger 100 is stored in the storage space 18, the side of the charger 100 close to the charger support seat 16 and the other two sides will automatically adhere to the protective film 200.

[0031] In this embodiment, the two protective film support seats 14 can be close to or away from each other to accommodate the length error of the protective film 200 caused by processing. Specifically, the support mechanism also includes a support seat driver 20 connected to the protective film support seat 14, and the support seat driver 20 is used to drive the two protective film support seats 14 to move toward or away from each other.

[0032] The specific type of the support base driver 20 is not limited, such as a motor, a cylinder, etc. In this embodiment, the support base driver 20 is a bidirectional cylinder.

[0033] In one embodiment, the charger support seat 16 can move up and down relative to the protective film support seat 14. When the charger support seat 16 moves downward, the charger support seat 16 can cooperate with the two protective film support seats 14 to form a storage space 18, thereby accommodating the charger 100. When performing the film coating operation, the charger support seat 16 can be controlled to rise first so that it is flush with the two protective film support seats 14, and then the protective film 200 and the charger 100 are placed on the protective film support seat 14 and the charger support seat 16 in turn, and the charger 100 is pressed downward to make the charger support seat 16 move downward. The protective film 200 will be deformed under the action of the charger 100 and fit together with the side of the charger 100 close to the charger support seat 16 and the other two opposite sides.

[0034] The coating machine 10 includes a reset mechanism 22, which includes a fixed frame 24, a movable frame 26 and an elastic reset member 28. The fixed frame 24 is connected to the collective and remains relatively fixed. The movable frame 26 is slidably connected to the fixed frame 24. The charger support seat 16 is relatively fixed to the movable frame 26. The two ends of the elastic reset member 28 are respectively connected to the fixed frame 24 and the movable frame 26. The movable frame 26 can be lifted and lowered relative to the fixed frame 24 and drive the charger support seat 16 to move. The elastic reset member 28 can generate an upward elastic force during the downward movement of the movable frame 26 relative to the fixed frame 24. When the charger 100 is pressed downward, the charger 100, the charger support seat 16 and the movable frame 26 move downward relative to the fixed frame 24, causing the elastic reset member 28 to deform, thereby generating an elastic force that drives the movable frame 26 to move upward. After the packaging is completed and the charger 100 is released, the movable frame 26 can move upward relative to the fixed frame 24 under the action of the elastic reset member 28, and drive the charger support seat 16 to move upward together until the charger support seat 16 is flush with the protective film support seat 14, so that the charger support seat 16 returns to the initial position for the next packaging.

[0035] The specific type of the elastic reset member 28 is not limited. In the present embodiment, the elastic reset member 28 is a spring, which is arranged vertically and has two ends connected to the fixed frame 24 and the movable frame 26 respectively.

[0036] Preferably, a slide rail and a slider are provided between the fixed frame 24 and the movable frame 26, and the slide rail and the slider are slidably matched, and one of the slide rail and the slider is relatively fixed to the fixed frame 24, and the other is relatively fixed to the movable frame 26, thereby achieving an effect of sliding connection between the fixed frame 24 and the movable frame 26.

[0037] In one embodiment, the film coating machine 10 further includes a clamping assembly 30 disposed between the two protective film support seats 14, and the clamping assembly 30 is configured to clamp two opposite sides of the charger 100 when the charger 100 is accommodated in the storage space 18. After the charger 100 is accommodated in the storage space 18, that is, after the movable frame 26 moves downward to the specified position, the charger 100 is clamped by the clamping assembly 30 to position the charger 100 at the position to prevent the charger 100 from rising under the action of the elastic reset member 28, and then the charger 100 is released. Since the two sides clamped by the clamping assembly 30 have been attached to the protective film 200 during the process of pressing the charger 100 downward, the clamping assembly 30 clamping the charger 100 will not affect the subsequent film coating operation.

[0038] The clamping assembly 30 includes two clamping jaws 32 arranged opposite to each other at intervals and a clamping driver for driving the two clamping jaws to move closer to each other or away from each other. The two clamping jaws 32 are arranged at intervals along the arrangement direction of the two protective film support seats 14, and the charger support seat 16 is located between the two clamping jaws 32. Before the charger 100 is pressed down, the two clamping jaws 32 can be moved closer to each other by the clamping jaw driver 34, so that the clamping jaws 32 are close to but not clamped to the charger 100. After the charger 100 moves downward to a specified position, the two clamping jaws 32 are moved closer to each other and clamped to the charger 100 by the clamping jaw driver 34 until the film coating is completed, and then the two clamping jaws 32 are moved away from each other by the clamping jaw driver 34, thereby releasing the charger 100, so that the charger support seat 16 can be reset to the initial position under the action of the elastic reset member 28.

[0039] The specific type of the clamping driver 34 is not limited. In the present embodiment, the clamping driver is a bidirectional cylinder.

[0040] Each clamping jaw 32 is provided with a clamping roller 36 . The clamping roller 36 is cylindrical and has a curved outer surface. By clamping the charger 100 with the clamping roller 36 , the protective film 200 can be prevented from being damaged by the clamping assembly 30 during the process of clamping the charger 100 .

[0041] In one embodiment, the coating machine 10 includes a horizontal coating mechanism 38 and a vertical coating mechanism 40. The horizontal coating mechanism 38 can move in a horizontal direction relative to the body 12, and is used to flatten the portion of the protective film 200 protruding from the side of the charger 100 and attach it to the corresponding side. The vertical coating mechanism 40 can move in a vertical direction relative to the body 12, and is used to flatten the portion of the protective film 200 protruding from the end face of the charger 100 and attach it to the corresponding end face. The protective film 200 is automatically attached to the three side surfaces when the charger 100 is pressed down. The horizontal wrapping mechanism 38 flattens the portion of the protective film 200 that vertically protrudes from the charger 100 and attaches it to the remaining side surface during horizontal movement. The vertical wrapping mechanism 40 flattens the portion of the protective film 200 that horizontally protrudes from the charger 100 and attaches it to the end surface during the lifting process. Ultimately, both the side surfaces and the end surfaces of the charger 100 can be covered by the protective film 200, thereby forming a more comprehensive protective effect. Moreover, the wrapping machine 10 can achieve an automatic wrapping effect without the need for workers to manually wrap, thereby greatly improving production efficiency and wrapping quality.

[0042] The vertical film coating mechanism 40 includes a first vertical film coating component 42 and a second vertical film coating component 44. The first vertical film coating component 42 can move from top to bottom to flatten the portion of the protective film 200 located below the charger 100 and attach it to the end surface. The second vertical film coating component 44 can move from bottom to top to flatten the portion of the protective film 200 located above the charger 100 and attach it to the end surface. By setting the vertical film coating mechanism 40 to include the first vertical film coating component 42 and the second vertical film coating component 44, one of which flattens the protective film 200 from bottom to top and the other flattens the protective film 200 from top to bottom, it is helpful to reduce the overall width of the protective film 200 in a flattened state. Specifically, the first vertical film coating component 42 and the second vertical film coating component 44 both act on the two end surfaces of the charger 100, that is, a part of the protective film 200 attached to the same end surface is flattened by the first vertical film coating component 42, and the other part is flattened by the second vertical film coating component 44.

[0043] There is an overlapping part in the vertical movement trajectory of the first vertical envelope component 42 and the second vertical envelope component 44, so that the part of the protective film 200 flattened by the first vertical envelope component 42 and the part flattened by the second vertical envelope component 44 overlap and bond together to form a fixing effect.

[0044] In this embodiment, the protective film 200 flattened by the second vertical coating component 44 is provided with adhesive. During the coating process, the first vertical coating component 42 can be moved upward first to flatten the protective film 200 located below the charger 100 and attach it to the lower part of the end surface of the charger 100. Then the second vertical coating component 44 moves downward to leave space for the movement of the second vertical coating component 44. Subsequently, the second vertical coating component 44 moves downward to flatten the protective film 200 located above the charger 100 and attach it to the upper part of the end surface of the charger 100. The second vertical coating component 44 moves to the protective film 200 flattened by the first vertical coating component 42, so that the part of the protective film 200 flattened by the first vertical coating component 42 and the part flattened by the second vertical coating component 44 overlap and are bonded together.

[0045] In one embodiment, the first vertical film-wrapping assembly 42 includes two first rollers 46, a first mounting frame 48, and a first vertical driver 50. The two first rollers 46 are arranged opposite to each other and are rotatably mounted on the first mounting frame 48. The first vertical driver 50 is connected to the first mounting frame 48 to drive the first mounting frame 48 and the first rollers 46 to move up and down. The two first rollers 46 are respectively located on opposite sides of the charger support seat 16. Each first roller 46 corresponds to an end face of the charger 100 and is used to flatten and attach the protective film 200 to the corresponding end face of the charger 100. The first mounting frame 48 is connected to the first vertical driver 50, and the first roller 46 is rotatably mounted on the first mounting frame 48. Therefore, the first vertical driver 50 can drive the first roller 46 to move upward. The upward movement of the first roller 46 flattens and attaches the protective film 200 located below the charger 100 to the end face. The first roller 46 is cylindrical and rotatably connected to the first mounting frame 48 , so that the protective film 200 will not be damaged during the process of flattening the protective film 200 .

[0046] The specific type of the first vertical driver 50 is not limited. In the present embodiment, the first vertical driver 50 is a one-way cylinder.

[0047] The number of the first vertical drivers 50 is not limited. For example, one driver may drive two first rollers 46 at the same time, or different drivers may separately drive the corresponding first rollers 46. In this embodiment, the number of the first mounting frames 48 and the first vertical drivers 50 are both two, each of the first mounting frames 48 is connected to a corresponding first vertical driver 50, and each of the first mounting frames 48 has a first roller 46 rotatably mounted thereon.

[0048] In one embodiment, the second vertical film-wrapping assembly 44 includes two second rollers 52, a second mounting frame 54, and a second vertical driver 56. The two second rollers 52 are arranged opposite to each other at intervals and are rotatably mounted on the second mounting frame 54. The second vertical driver 56 is connected to the second mounting frame 54 to drive the second mounting frame 54 and the second rollers 52 to move up and down. The two second rollers 52 can move to opposite sides of the charger support seat 16, and each second roller 52 corresponds to an end face of a charger 100, that is, each end face of the charger 100 corresponds to a first roller 46 and a second roller 52. When the second roller 52 moves downward under the action of the second vertical driver 56, the second roller 52 can flatten the protective film 200 located above the charger 100 and attach it to the end face, and the second roller 52 will not damage the protective film 200 in the process of flattening the protective film 200.

[0049] The specific type of the second vertical driver 56 is not limited. In the present embodiment, the second vertical driver 56 is a one-way cylinder.

[0050] The number of the first vertical drivers 50 is not limited. For example, one driver may drive the two second rollers 52 at the same time, or different drivers may drive the corresponding second rollers 52 separately. In this embodiment, the number of the second vertical drivers 56 is one, and the number of the second mounting frames 54 is two. Both second mounting frames 54 are connected to the second vertical drivers 56, and each second mounting frame 54 is rotatably mounted with a second roller 52.

[0051] Preferably, the two second mounting frames 54 can be moved closer to each other or farther away from each other so as to accommodate dimensional errors caused by processing of the charger 100 or errors caused by placement.

[0052] In one embodiment, the horizontal encapsulation mechanism 38 includes a first horizontal encapsulation component 58 and a second horizontal encapsulation component 60. The first horizontal encapsulation component 58 and the second horizontal encapsulation component 60 are capable of moving in opposite directions toward the charger 100 mounting seat and flattening portions of the protective film 200 located on different sides of the charger 100 and attaching them to the side of the charger 100 away from the charger 100 mounting seat.

[0053] There is an overlapping part in the horizontal movement trajectory of the first horizontal envelope component 58 and the second horizontal envelope component 60, so that the part of the protective film 200 flattened by the first horizontal envelope component 58 and the part flattened by the second horizontal envelope component 60 overlap and bond together to form a fixing effect.

[0054] Specifically, the protective film 200 flattened by the second horizontal envelope component 60 is provided with adhesive. During the wrapping process, the first horizontal envelope component 58 can be moved toward the charger 100 first, and the portion of the protective film 200 protruding from the side of the charger 100 and close to the first horizontal envelope component 58 is flattened and attached to the corresponding side of the charger 100. Then, the first horizontal envelope component 58 moves away from the charger 100 to leave space for the movement of the second horizontal envelope component 60. Subsequently, the second horizontal envelope component 60 moves toward the charger 100, and the portion of the protective film 200 protruding from the side of the charger 100 and close to the second horizontal envelope component 60 is flattened and attached to the corresponding side of the charger 100, and the portion flattened by the second horizontal envelope component 60 overlaps with the portion flattened by the first horizontal envelope component 58 and is bonded together.

[0055] The first horizontal film encapsulation assembly 58 includes a first horizontal driver 62, a third mounting frame 64, and a third roller 66. The first horizontal driver 62 is connected to the machine body 12, the third mounting frame 64 is connected to the first horizontal driver 62, and the third roller 66 is rotatably mounted on the third mounting frame 64. The first horizontal driver 62 is used to drive the third mounting frame 64 and the third roller 66 to move in the horizontal direction. When the first horizontal driver 62 drives the third roller 66 to move toward the charger 100, the third roller 66 can flatten the portion of the protective film 200 protruding from the side of the charger 100 and close to the third roller 66 and attach it to the side of the charger 100 away from the charger support seat 16, and the protective film 200 will not be damaged during the flattening process.

[0056] The specific type of the first horizontal driver 62 is not limited. In the present embodiment, the first horizontal driver 62 is a one-way cylinder.

[0057] The second vertical driver 56 of the second vertical film-wrapping mechanism 40 is arranged on the third mounting frame 64, so the first horizontal driver 62 drives the third roller 66 to move with the second vertical film-wrapping mechanism 40 during the horizontal movement, and the second vertical driver 56 can drive the second roller 52 to rise and fall relative to the third roller 66. Therefore, in the process of using the third roller 66 to flatten the protective film 200, the second mounting frame 54 and the second roller 52 can be controlled to rise by the second vertical driver 56 to prevent them from affecting the horizontal movement of the third roller 66.

[0058] The first horizontal film-wrapping assembly 58 further includes a third vertical driver 68 connected to the first horizontal driver 62, and the third mounting frame 64 is connected to the third vertical driver 68. The third vertical driver 68 is used to drive the third mounting frame 64 and the third roller 66 mounted on the third mounting frame 64 and the second vertical film-wrapping assembly 44 to perform lifting and lowering movements. By providing the third vertical driver 68, the third mounting frame 64 and the third roller 66 can not only move in the horizontal direction, but also in the vertical direction, so as to adjust the relative positions of the third mounting frame 64 and the third roller 66 relative to the protective film support seat 14 in the vertical direction.

[0059] The specific type of the third vertical driver 68 is not limited. In the present embodiment, the third vertical driver 68 is a one-way cylinder.

[0060] The second horizontal film encapsulation assembly 60 includes a second horizontal driver 70, a fourth mounting frame 72, and a fourth roller 74. The second horizontal driver 70 is mounted on the machine body 12 and is spaced apart from the first horizontal driver 62 in a direction perpendicular to the direction of movement thereof. The fourth mounting frame 72 is connected to the second horizontal driver 70. The fourth roller 74 is rotatably mounted on the fourth mounting frame 72 and is spaced apart from the third roller 66. The second horizontal driver 70 is used to drive the fourth mounting frame 72 and the fourth roller 74 to move in the horizontal direction. When the fourth roller 74 moves toward the charger 100 under the drive of the second horizontal driver 70, the fourth roller 74 can flatten the portion of the protective film 200 protruding from the side of the charger 100 and close to the fourth roller 74 and attach it to the side of the charger 100 away from the charger support seat 16, and the protective film 200 will not be damaged during the flattening process.

[0061] The specific type of the second horizontal driver 70 is not limited. In the present embodiment, the second horizontal driver 70 is a one-way cylinder.

[0062] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
