[0022] This application provides a coating device capable of coating electronic product chargers, batteries, and other products.

[0023] Please refer to Figures 1 to 4 The coating device 100 of this application embodiment includes a frame 10, a feeding mechanism 20, a coating mechanism 30, and a transfer mechanism 40. The feeding mechanism 20 is connected to the frame 10; the feeding mechanism 20 includes a feeding assembly 21, a first platform 221, a first guide roller 222, a second guide roller 23, a platform driver 223, and a receiving assembly 24. The feeding assembly 21 is used to support the sticker roll, which includes a backing paper and multiple coated stickers. The first platform 221 and the first guide roller 222 are arranged along a first direction X between the second guide roller 23 and the feeding assembly 21. The first guide roller 222 is connected to the first platform 221, and the first guide roller 222 and the first platform 221 are spaced apart along a second direction Z, which is perpendicular to the first direction X and the first guide roller 222. The first guide roller 222 is used to tension the sticker roll between the first platform 221 and the second guide roller 23. The platform driver 223 is connected to the first platform 221 and is used to drive the first platform 221 and the first guide roller 222 to reciprocate along the first direction X; the receiving assembly 24 is used to collect the bottom paper.

[0024] The coating mechanism 30 is connected to the frame 10 and is used to apply coating stickers to the product. The transfer mechanism 40 is connected to the frame 10 and is used to move the coating stickers in the feeding mechanism 20 to the coating mechanism 30.

[0025] The frame 10 serves as a support structure in the coating device 100, supporting the feeding mechanism 20, the coating mechanism 30, and the transfer mechanism 40.

[0026] The feeding assembly 21 is used to supply the coating sticker for the product.

[0027] Multiple coated stickers in the sticker roll are attached to a backing paper and arranged sequentially along the extension direction of the backing paper. The backing paper is wound to form a roll. A feeding assembly 21 is used to support the wound sticker roll. Optionally, the feeding assembly 21 may include a feeding roller 211 connected to the frame 10, on which the sticker roll can be fitted and rotated. Optionally, the feeding assembly 21 may include a clamping member rotatably connected to the frame 10, which clamps the sticker roll and allows it to rotate synchronously with the clamping member; for example, the sticker roll may include a support shaft, with the backing paper wound on the support shaft, and the clamping member clamping the support shaft.

[0028] The first platform 221 can support the unfolded sticker roll and other components that collect the wrapping sticker, making it convenient for other components to remove the wrapping sticker located on the first platform 221.

[0029] Both the first guide roller 222 and the second guide roller 23 are used to guide the bottom paper, causing it to move towards the take-up assembly 24 in a preset direction. Optionally, the first guide roller 222 can be rotatably connected to the first platform 221. The friction between the first guide roller 222 and the bottom paper is small, which can prevent damage to the bottom paper and ensure stable movement of the bottom paper towards the take-up assembly 24. Optionally, the first guide roller 222 can also be fixedly connected to the first platform 221. Optionally, the second guide roller 23 can be rotatably connected to the frame 10. The friction between the second guide roller 23 and the bottom paper is small. Optionally, the second guide roller 23 can also be fixedly connected to the frame 10.

[0030] The first platform 221 and the first guide roller 222 are both disposed between the second guide roller 23 and the feeding mechanism 20 along a first direction X. Optionally, the first direction X can be a direction parallel to the horizontal plane. Optionally, the first direction X can also be disposed at an acute angle to the horizontal plane.

[0031] The first guide roller 222 can be positioned on either side of the first platform 221 along the second direction Z. The second direction Z is perpendicular to the first guide roller 222, meaning it is perpendicular to the length of the first guide roller 222. Optionally, the second direction Z can be vertical. Optionally, the second direction Z can also be set at an acute angle to the vertical direction. For an example, please refer to [reference needed]. Figure 3 and Figure 4 The first guide roller 222 is located below the first platform 221, and the top of the first platform 221 is used to support the sticker roll. Optionally, the first guide roller 222 can also be located above the first platform 221.

[0032] The first guide roller 222 is used to tension the sticker roll between the first platform 221 and the second guide roller 23. That is, when the feeding mechanism 20 is used, the unfolded sticker roll passes through the first platform 221 and then passes through the first guide roller 222 and the second guide roller 23 in sequence.

[0033] The platform driver 223 can drive the first platform 221 to reciprocate along the first direction X, so that the first platform 221 drives the first guide roller 222 to reciprocate.

[0034] When the control platform driver 223 drives the first platform 221 and the first guide roller 222 away from the second guide roller 23 along the first direction X, the distance between the first platform 221 and the feeding assembly 21 decreases, and the distance between the first guide roller 222 and the second guide roller 23 increases. As a result, the backing paper originally located on the first platform 221 moves closer to the first guide roller 222, and the backing paper originally located between the first platform 221 and the first guide roller 222 moves closer to the second guide roller 23. When the feeding mechanism 20 is in use, the wrapping sticker on the first platform 221 can be fixed first. When the platform driver 223 drives the first platform 221 and the first guide roller 222 away from the second guide roller 23 along the first direction X, the backing paper originally located on the first platform 221 moves relative to the fixed wrapping sticker, and the fixed wrapping sticker gradually detaches from the backing paper. Compared to using a suction cup to directly detach the wrapping sticker from the backing paper, the gradual detachment of the wrapping sticker from the backing paper reduces the force on the wrapping sticker and prevents damage.

[0035] Optionally, the platform driver 223 may include a cylinder, electric actuator, or hydraulic actuator connected to the frame 10.

[0036] The take-up assembly 24 is used to collect the backing paper after the wrapping sticker has been removed. The take-up assembly 24 can move the unfolded backing paper towards itself, thereby collecting the backing paper. Optionally, the take-up assembly 24 may include a take-up roller 241 and a take-up driver 242, the take-up driver 242 being used to drive the take-up roller 241 to rotate, causing the backing paper to wind onto the take-up roller 241. Optionally, the take-up assembly 24 may also include two opposing pressure rollers and a pressure roller driver, the pressure roller driver being used to drive the two pressure rollers to rotate in opposite directions, and the rotation of the two pressure rollers can move the backing paper between the two pressure rollers.

[0037] The transfer mechanism 40 can collect the wrapping sticker from the feeding mechanism 20 and move it to the wrapping mechanism 30. Optionally, the transfer mechanism 40 can directly collect the wrapping sticker from the base paper. Optionally, the feeding mechanism 20 can also be configured to have other components first remove the wrapping sticker from the base paper, and then the transfer mechanism 40 can collect the wrapping sticker from those other components.

[0038] The coating mechanism 30 is able to receive the coating sticker from the transfer mechanism 40 and attach the coating sticker to the product.

[0039] For example, when the wrapping device 100 is used, the rolled-up sticker roll is placed on the feeding assembly 21, the sticker roll is unrolled and sequentially passes around the first platform 221, the first guide roller 222 and the second guide roller 23 and then connected to the receiving assembly 24; the first guide roller 222 tensions the sticker roll between the first platform 221 and the second guide roller 23.

[0040] When applying the film-coated sticker, the control platform driver 223 drives the first platform 221 and the first guide roller 222 to approach the second guide roller 23 along the first direction X. Then, the control take-up assembly 24 drives the sticker roll to approach the take-up assembly 24. After the film-coated sticker on the sticker roll moves to the first platform 221, the control take-up assembly 24 stops moving.

[0041] Then, the control transfer mechanism 40 fixes a wrapping sticker on the first platform 221, and the control platform driver 223 drives the first platform 221 and the first guide roller 222 away from the second guide roller 23 along the first direction X. The distance between the first platform 221 and the feeding assembly 21 decreases, and the distance between the first guide roller 222 and the second guide roller 23 increases. The bottom paper originally located on the first platform 221 moves closer to the first guide roller 222, and the bottom paper originally located between the first platform 221 and the first guide roller 222 moves closer to the second guide roller 23. As the bottom paper moves, it gradually detaches from the wrapping sticker fixed by the transfer mechanism 40. After the bottom paper is completely detached from the wrapping sticker fixed by the transfer mechanism 40, the control transfer mechanism 40 moves the wrapping sticker to the wrapping mechanism 30. The control wrapping mechanism 30 then receives the wrapping sticker and attaches it to the product. This process of attaching wrapping stickers is repeated, sequentially attaching multiple wrapping stickers from the bottom paper to multiple products.

[0042] The beneficial effects of this application embodiment are as follows: the feeding mechanism 20 of this application embodiment can provide the coating sticker, the transfer mechanism 40 can transfer the coating sticker to the coating mechanism 30, and the coating mechanism 30 can attach the coating sticker to the product. Compared with manual film application, the use of the feeding mechanism 20, the transfer mechanism 40 and the coating mechanism 30 can improve the efficiency of applying the coating sticker and the coating quality. The system comprises a first guide roller 222, a first platform 221, a second guide roller 23, and a platform driver 223. When applying the film-coating sticker, after the film-coating sticker is fixed on the first platform 221 by the transfer mechanism 40, the platform driver 223 drives the first platform 221 and the first guide roller 222 away from the second guide roller 23 along a first direction X. At this time, the distance between the first platform 221 and the feeding assembly 21 decreases, while the distance between the first guide roller 222 and the second guide roller 23 increases. Consequently, the backing paper, originally located on the first platform 221, moves closer to the first guide roller 222, and the backing paper, originally located between the first platform 221 and the first guide roller 222, moves closer to the second guide roller 23. As the backing paper moves, it gradually detaches from the film-coating sticker fixed by the transfer mechanism 40. Compared to using a suction cup to directly detach the film-coating sticker from the backing paper, this gradual detachment reduces the force on the film-coating sticker and prevents damage. This embodiment of the application solves the technical problem of easy damage to the film-coating sticker when separating from the backing paper.

[0043] In some embodiments, please refer to Figures 3 to 5 The feeding mechanism 20 also includes a first suction cup 251, a suction cup rotation driver 252, and a suction cup movement driver 253. The first suction cup 251 is located on the side of the first platform 221 away from the first guide roller 222 along the second direction Z, and is used to pick up the film sticker on the first platform 221. The suction cup rotation driver 252 is connected to the first suction cup 251 and is used to drive the first suction cup 251 to rotate around a first axis 224, which is parallel to the first guide roller 222. The suction cup movement driver 253 is connected to the suction cup rotation driver 252 and is used to drive the first suction cup 251 and the suction cup movement driver 253 to move closer to or away from the first platform 221 along the second direction Z.

[0044] The suction cup rotation driver 252 can drive the first suction cup 251 to rotate, so that the adsorption surface of the first suction cup 251 faces the first platform 221 along the second direction Z, facilitating the first suction cup 251 to pick up the coating sticker on the first platform 221. The suction cup rotation driver 252 can also drive the first suction cup 251 to rotate until the adsorption surface faces the transfer mechanism 40, facilitating the transfer mechanism 40 to collect the coating sticker on the first suction cup 251. The first suction cup 251 is connected to a negative pressure device.

[0045] Optionally, the suction cup rotation driver 252 is used to drive the first suction cup 251 to rotate 180°, so that the adsorption surface of the first suction cup 251 can move away from the first platform 221 along the second direction Z. Optionally, the suction cup rotation driver 252 may include a rotary cylinder, a stepper motor or a servo motor, etc., which can easily control the rotation angle of the first suction cup 251.

[0046] The suction cup moving driver 253 drives the first suction cup 251 to move along the first direction X via the suction cup rotating driver 252. When the suction cup moving driver 253 moves the first suction cup 251 closer to the first platform 221 along the first direction X, the first suction cup 251 can pick up the film sticker on the first platform 221. When the suction cup moving driver 253 moves the first suction cup 251 away from the first platform 221 along the first direction X, the suction cup rotating driver 252 can drive the first suction cup 251 to rotate, so that the film sticker on the first suction cup 251 moves towards the transfer mechanism 40.

[0047] Optionally, the suction cup moving driver 253 may include a linear motor, cylinder or lead screw transmission mechanism, etc., to facilitate the control of the first suction cup 251 and the suction cup rotating driver 252 to move to a preset position.

[0048] When applying the film-coated sticker, the control platform driver 223 drives the first platform 221 and the first guide roller 222 to approach the second guide roller 23 along the first direction X. The control take-up assembly 24 then moves the sticker roll closer to the take-up assembly 24. When the film-coated sticker on the sticker roll moves to the first platform 221 and faces the first suction cup 251 along the second direction Z, the control take-up assembly 24 stops. Then, the control suction cup rotation driver 252 drives the first suction cup 251 to rotate, so that the suction surface of the first suction cup 251 faces the film-coated sticker on the first platform 221 along the second direction Z. The control suction cup movement driver 253 then drives the first suction cup 251 to approach the first platform 221 along the first direction X, so that the first suction cup 251 holds the film-coated sticker and the backing paper against the first platform 221 along the first direction X, and the control first suction cup 251 picks up and fixes the film-coated sticker. Then, the control platform driver 223 drives the first platform 221 and the first guide roller 222 away from the second guide roller 23 along the first direction X, so that the film sticker sucked by the first suction cup 251 gradually detaches from the base paper.

[0049] After the first suction cup 251 picks up the coating sticker and detaches it from the backing paper, the suction cup moving driver 253 drives the first suction cup 251 away from the first platform 221 along the first direction X. Then, the suction cup rotating driver 252 controls the first suction cup 251 to rotate so that the adsorption surface of the first suction cup 251 faces the transfer mechanism 40. Then, the transfer mechanism 40 is controlled to transfer the coating sticker on the first suction cup 251 to the coating mechanism 30.

[0050] The beneficial effects of this embodiment are as follows: the suction cup moving driver 253 and the suction cup rotating driver 252 can drive the first suction cup 251 to change position, so that the first suction cup 251 can move onto the coating sticker and stably pick up the coating sticker. The suction cup moving driver 253 and the suction cup rotating driver 252 can also drive the coating sticker to change position through the first suction cup 251, so that the coating sticker on the first suction cup 251 is facing the feeding mechanism 20, so that the feeding mechanism 20 can stably transfer the coating sticker.

[0051] In some embodiments, please refer to Figure 3 and Figure 4 The feeding mechanism 20 also includes a fixing component 26, which is used to fix the sticker roll between the first platform 221 and the feeding component 21.

[0052] When the control platform driver 223 drives the first platform 221 to move along the first direction X, the sticker roll on the first platform 221 may move synchronously with the first platform 221, which may cause the sticker roll on the feeding assembly 21 to unroll, making it difficult to control the unrolled length of the sticker roll. The fixing component 26 can fix the sticker roll between the first platform 221 and the feeding assembly 21, preventing the sticker roll on the feeding assembly 21 from unrolling due to the movement of the first platform 221, so that the unrolled length of the sticker roll can be stably controlled.

[0053] Optionally, the fixing component 26 may include a pressure plate, a clamp, or an adsorption device.

[0054] When applying the film-coated sticker, after the take-up component 24 moves the sticker a certain distance and stops, the sticker roll on the feed component 21 unfolds to a set length, and the fixing component 26 fixes the sticker roll between the first platform 221 and the feed component 21. Before the take-up component 24 moves the sticker again, the fixing component 26 releases the sticker roll between the first platform 221 and the feed component 21, allowing the take-up component 24 to unfold the sticker roll on the feed component 21.

[0055] In other embodiments, the feeding assembly 21 includes a feeding driver for driving the sticker roll to rotate. By controlling the feeding driver, the unfolded length of the sticker roll can be accurately controlled, preventing the sticker roll on the feeding assembly 21 from unwinding due to movement of the first platform 221.

[0056] In some embodiments, please refer to Figure 3 and Figure 4The fixing assembly 26 includes a second platform 261, a pressing member 262, and a pressing driver 263. The second platform 261 is located on the side of the first platform 221 along the first direction X, close to the feeding assembly 21. The pressing member 262 is located on the side of the second platform 261 along the second direction Z and is used to hold the sticker roll on the second platform 261. The pressing driver 263 is connected to the pressing member 262 and is used to drive the pressing member 262 to move closer to or away from the second platform 261 along the second direction Z.

[0057] Controlling the film pressing driver 263 to drive the film pressing component 262 towards the second platform 261 in the second direction Z enables the film pressing component 262 to hold and fix the unfolded sticker roll onto the second platform 261. Controlling the film pressing driver 263 to drive the film pressing component 262 away from the second platform 261 in the second direction Z enables the film pressing component 262 to release the sticker roll, allowing the sticker roll on the second platform 261 to move.

[0058] In some embodiments, please refer to Figures 3 to 5 The wrapping mechanism 30 also includes a first clamping guide roller 271, a second clamping guide roller 272, and a clamping roller driver. In the first direction X, the first clamping guide roller 271 and the second clamping guide roller 272 are located between the take-up assembly 24 and the second guide roller 23. In the second direction Z, the first clamping guide roller 271 and the second clamping guide roller 272 are located on the side of the first guide roller 222 away from the first platform 221. The first clamping guide roller 271 and the second clamping guide roller 272 are used to clamp the base paper. The first clamping guide roller 271 is fixedly connected to the frame 10, and the second clamping guide roller 272 is connected to the clamping roller driver, which drives the second clamping guide roller 272 to rotate around its own axis.

[0059] When the wrapping device 100 is in use, the unfolded sticker roll passes over the second guide roller 23, then between the first clamping guide roller 271 and the second clamping guide roller 272, and is then connected to the take-up assembly 24. When the control roller driver drives the second clamping guide roller 272 to rotate, the backing paper between the first clamping guide roller 271 and the second clamping guide roller 272 moves toward the take-up assembly 24. When the roller driver stops operating, the first clamping guide roller 271 and the second clamping roller hold and fix the backing paper, which can accurately control the unfolded length of the sticker roll.

[0060] In some embodiments, please refer to Figures 3 to 5 The take-up assembly 24 includes a take-up roller 241 and a take-up driver 242, which drives the take-up roller 241 to rotate. The take-up driver 242 is also connected to a first clamping guide roller 271, and the take-up driver 242 is a clamping driver, which drives the first clamping guide roller 271 and the take-up roller 241 to rotate simultaneously. While controlling the bottom paper between the first clamping guide roller 271 and the second clamping guide roller 272 to move towards the take-up assembly 24, the take-up roller 241 is controlled to collect the bottom paper.

[0061] In some embodiments, please refer to Figures 3 to 5 The feeding mechanism 20 also includes a third guide roller 28 and a fourth guide roller 29. The third guide roller 28 is used to guide the sticker roll between the fixing component 26 and the feeding component 21, and the fourth guide roller 29 is used to guide the bottom paper between the first clamping guide roller 271 and the second clamping guide roller 272 and the receiving component 24.

[0062] In some embodiments, please refer to Figure 6 The transfer mechanism 40 includes a second suction cup 41, a transfer suction cup driver 42, an elastic buffer 43, and a transfer driver 44. The second suction cup 41 is used to pick up the coating sticker from the feeding mechanism 20. The transfer suction cup driver 42 is connected to the second suction cup 41 and is used to drive the second suction cup 41 towards or away from the feeding mechanism 20 and the coating mechanism 30 along a second direction Z. The elastic buffer 43 is connected between the transfer suction cup driver 42 and the second suction cup 41. The transfer driver 44 is connected to the transfer suction cup driver 42 and is used to drive the transfer suction cup driver 42 to move between the feeding mechanism 20 and the coating mechanism 30.

[0063] The transfer suction cup driver 42 can drive the second suction cup 41 to move closer to or away from the component supporting the film-coated sticker in the feeding mechanism 20 along the second direction Z. Optionally, in the second direction Z, the second suction cup 41 can be located on the side of the first platform 221 away from the first guide roller 222, and the transfer suction cup driver 42 is used to drive the second suction cup 41 to move closer to or away from the first platform 221 along the second direction Z. The second suction cup 41 is used to pick up the film-coated sticker on the first platform 221.

[0064] Optionally, in the second direction Z, the second suction cup 41 can be located on the side of the first suction cup 251 away from the first platform 221. The transfer suction cup driver 42 is used to drive the second suction cup 41 to move closer to or away from the first suction cup 251 in the second direction Z. The second suction cup 41 is used to pick up the coating sticker on the first suction cup 251. The second suction cup 41 is connected to a vacuum device. When the second suction cup 41 picks up the coating sticker on the first suction cup 251, the vacuum device connected to the first suction cup 251 releases the vacuum action.

[0065] The transfer suction cup driver 42 can drive the second suction cup 41 to move closer to or further away from the component in the coating mechanism 30 that receives the coating sticker along the second direction Z, so as to transfer the coating sticker on the second suction cup 41 into the coating mechanism 30.

[0066] Optionally, the transfer suction cup driver 42 may include a cylinder, a hydraulic push rod, or an electric push rod, etc.

[0067] When the control transfer mechanism 40 drives the second suction cup 41 to approach the feeding mechanism 20 along the second direction Z and contact the coating sticker on the feeding mechanism 20, the second suction cup 41 impacts the feeding mechanism 20. The elastic buffer 43 can buffer the force generated when the second suction cup 41 impacts the feeding mechanism 20, thus preventing damage to the second suction cup 41 and the feeding mechanism 20. For example, when the second suction cup 41 picks up the coating sticker on the first suction cup 251, it can reduce the force generated when the second suction cup 41 impacts the first suction cup 251, thus preventing damage to the second suction cup 41 and the first suction cup 251.

[0068] Optionally, the elastic buffer 43 may include a spring, an airbag, or a rubber pad.

[0069] The transfer driver 44 can drive the second suction cup 41 to move between the feeding mechanism 20 and the coating mechanism 30 by driving the transfer suction cup driver 42.

[0070] When the transfer mechanism 40 is in use, the transfer driver 44 drives the transfer suction cup driver 42 and the second suction cup 41 to move from the coating mechanism 30 to the feeding mechanism 20. The transfer suction cup driver 42 drives the second suction cup 41 to approach the feeding mechanism 20 along the second direction Z, and the second suction cup 41 picks up the coating sticker. Then, the transfer suction cup driver 42 drives the second suction cup 41 to move away from the feeding mechanism 20 along the second direction Z. The transfer driver 44 then drives the transfer suction cup driver 42 and the second suction cup 41 to move from the feeding mechanism 20 to the coating mechanism 30. The transfer suction cup driver 42 drives the second suction cup 41 to approach the coating mechanism 30 along the second direction Z, and the vacuum device connected to the second suction cup 41 inflates the second suction cup 41. The second suction cup 41 releases the coating sticker, and the coating sticker is transferred from the feeding mechanism 20 to the coating mechanism 30.

[0071] Optionally, the transfer driver 44 may include a cylinder, a linear motor, a lead screw drive mechanism, a hydraulic push rod, etc.

[0072] The beneficial effects of this embodiment are as follows: the transfer driver 44 and the transfer suction cup driver 42 can drive the second suction cup 41 to move between the feeding mechanism 20 and the coating mechanism 30, so that the second suction cup 41 can pick up the coating sticker in the feeding mechanism 20 and release the coating sticker into the coating mechanism 30, so that the coating sticker is stably transferred from the feeding mechanism 20 to the coating mechanism 30. The elastic buffer 43 can buffer the force generated when the second suction cup 41 collides with the feeding mechanism 20, and can prevent damage to the second suction cup 41 and the feeding mechanism 20.

[0073] In some embodiments, please refer to Figures 7 to 9The coating mechanism 30 includes a turntable 31, a coating rotation driver 33, a positioning member 32, and a coating assembly 34. The coating rotation driver 33 is connected to the turntable 31 and drives the turntable 31 to rotate around a second axis 331 extending along a second direction Z. The positioning member 32 is connected to one end of the turntable 31 along the second direction Z, and a positioning groove 321 is provided at the end of the positioning member 32 away from the turntable 31 along the second direction Z. The positioning groove 321 is used to position the coating sticker and the product. The coating assembly 34 is used to wrap the coating sticker in the positioning groove 321 onto the product.

[0074] The turntable 31 can support the positioning member 32. Optionally, the turntable 31 can be a circular plate structure, and the second axis 331 is the axis of the turntable 31. Optionally, the turntable 31 can also be a polygonal plate structure, and the second axis 331 can be the center line of the turntable 31.

[0075] The coating rotation driver 33 drives the positioning member 32 to rotate around the second axis 331 by driving the turntable 31 to rotate. Optionally, the coating rotation driver 33 may include a stepper motor or servo motor connected to the frame 10.

[0076] The positioning groove 321 is used to position the wrapping sticker and the product. When the wrapping sticker and the product are placed in the positioning groove 321, the groove wall of the positioning groove 321 can restrict the position of the wrapping sticker and the product. Depending on the specific shape of the product, the positioning groove 321 can be configured to restrict different shapes of the product. For example, when the product is a charger for an electronic product, the groove wall of the positioning groove 321 can be provided with two slots 323 that are adapted to the two prongs of the charger. Placing the prongs of the charger into the slots 323 can position the charger in the positioning groove 321.

[0077] Optionally, multiple positioning elements 32 can be provided, and the multiple positioning elements 32 are distributed at intervals around the second axis 331. While one positioning element 32 receives the wrapping sticker, products can be placed into the positioning element 32 or wrapped at other workstations, which can improve wrapping efficiency. Optionally, a positioning element 32 can also be provided on the edge of the turntable 31.

[0078] When the coating mechanism 30 is in use, the transfer mechanism 40 first transfers the coating sticker into the positioning groove 321, and then places the product on the coating sticker. The coating sticker is then attached to one outer wall of the product. The coating rotation driver 33 drives the positioning member 32 to rotate around the second axis 331 to different positions via the drive turntable 31, enabling operation of the coating sticker and the product at different positions. When the coating rotation driver 33 drives the positioning member 32 to the position of the coating assembly 34 via the drive turntable 31, the coating assembly 34 wraps the coating sticker in the positioning groove 321 onto the product.

[0079] In some embodiments, please refer to Figures 7 to 9 The turntable 31 is provided with two positioning holes 311 communicating with the positioning groove 321. The positioning holes 311 extend along the second direction Z. The wrapping assembly 34 includes two side-push film members 341 and a side-push driver 342. The side-push film members 341 are located on the side of the positioning hole 311 away from the positioning groove 321 along the second direction Z. The two side-push film members 341 are spaced apart along a direction perpendicular to the second direction Z. The two side-push film members 341 are used to abut against two opposite outer walls of the product along their spaced direction. The side-push driver 342 is used to drive the side-push film members 341 to move through the positioning holes 311 into the positioning groove 321 so that the side-push film members 341 abut against the wrapping sticker on the product.

[0080] Optionally, two connecting holes 322 extending through the positioning groove 321 along the second direction Z can be provided on the groove wall of the positioning groove 321, and each positioning hole 311 is connected to the positioning groove 321 through a connecting hole 322. Optionally, the positioning groove 321 can be set as a through groove that penetrates the positioning member 32, and the positioning hole 311 is directly connected to the positioning groove 321.

[0081] In the spaced direction of the two side-push film members 341, the two side-push film members 341 are used to abut against two opposite outer walls of the product, that is, the space between the two side-push film members 341 can accommodate the product. The side-push driver 342 is used to drive the side-push film member 341 to move through the positioning hole 311 into the positioning groove 321, so that the side-push film member 341 abuts the film sticker against the product. In other words, the side-push driver 342 can drive the side-push film member 341 to move, so that the side-push film member 341 abuts and attaches the film sticker in the positioning groove 321 to the outer wall of the product.

[0082] Optionally, the side-push film component 341 may include a roller rotatably connected to the side-push driver 342. When the side-push driver 342 pushes the side-push film component 341 to move, the roller can roll on the film-covering sticker, and the friction between the roller and the film-covering sticker is small. Optionally, the side-push film component 341 may also include a push spatula. Optionally, the side-push driver 342 may be connected to two side-push film components 341 respectively via two connecting rods. The connecting rods can pass through the positioning hole 311 to connect the side-push film component 341 in the positioning groove 321 to the side-push driver 342. Optionally, the side-push driver 342 may be connected to two side-push film components 341 respectively via two connecting plates.

[0083] Optionally, when the side of the product in the positioning groove 321 is parallel to the second direction Z, the side push driver 342 can be used to drive the side push film 341 to move along the second direction Z, and the side push film 341 can move on the side wall of the product. Optionally, when the side of the product in the positioning groove 321 intersects with the second direction Z, the side push driver 342 can also be used to drive the side push film 341 to move in a direction that forms a certain angle with the second direction Z, and the side push film 341 can move on the side wall of the product.

[0084] Optionally, the side push drive 342 may include a cylinder or electric push rod connected to the frame 10.

[0085] For example, when the wrapping mechanism 30 is in use, when the wrapping rotation driver 33 drives the positioning member 32 to rotate to the position of the wrapping assembly 34 via the drive turntable 31, the product is held and fixed against the positioning member 32. Then, the side push driver 342 is controlled to drive the side push film member 341 to move through the positioning hole 311 into the positioning groove 321. The two side push film members 341 push the wrapping sticker against the two opposite outer walls of the product. The side push film members 341 continue to move on the outer walls of the product and push the wrapping sticker to adhere to the outer walls of the product. Then, the side push driver 342 is controlled to drive the side push film member 341 to reset, releasing the fixation of the product.

[0086] The beneficial effects of this embodiment are as follows: The positioning hole 311 and the positioning groove 321 are interconnected, providing a channel for the movement of the side-push film piece 341, allowing the side-push driver 342 to drive the side-push film piece 341 smoothly into the positioning groove 321. The push driver drives the two side-push film pieces 341 to move within the positioning groove 321, enabling the film-covering sticker to be attached to the two opposite sidewalls of the product, resulting in high efficiency in attaching the film-covering sticker.

[0087] In some embodiments, please refer to Figures 7 to 9 The wrapping assembly 34 also includes two push-up film members 343, two push-up drivers 344, and a push-up moving driver 345. The push-up film members 343 are located on the side of the positioning groove 321 away from the side push-up film members 341 along the second direction. In the interval direction of the two side push-up film members 341, the two push-up film members 343 are respectively located on both sides of the two side push-up film members 341. The push-up film members 343 are used to abut against the outer wall of the product away from the positioning hole 311 along the second direction Z. Each push-up driver 344 is connected to one push-up film member 343 and is used to drive the push-up film member 343 to move along the interval direction of the two push-up film members 343. The push-up moving driver 345 is connected to the two push-up drivers 344 and is used to drive the two push-up drivers 344 to move closer to or away from the positioning member 32 along the second direction Z.

[0088] The push-up film component 343 is used to push the film-covering sticker onto the product after the side-push film component 341 pushes it onto the product, and then pushes the film-covering sticker onto the outer wall of the product along the second direction Z away from the positioning hole 311. Optionally, the push-up film component 343 may include a roller or a pusher, etc. For example, the two push-up film components 343 are a pusher and a roller, respectively.

[0089] In the spaced direction between the two side-push film members 341, two top-push film members 343 are respectively disposed on both sides of the two side-push film members 341. When the top-push moving driver 345 drives the two top-push drivers 344 to approach the positioning member 32 along the second direction Z, the two top-push film members 343 are respectively located on both sides of the product and the wrapping sticker. Optionally, the top-push moving driver 345 may include a cylinder or an electric push rod, etc.

[0090] The pusher film member 343 is used to abut against the outer wall of the product at the end away from the positioning hole 311 along the second direction Z. When the pusher driver 344 drives the pusher film member 343 to move along the interval direction between the two pusher film members 343, the pusher film member 343 can abut against the outer wall of the product at the end away from the positioning hole 311 along the second direction Z, and move on the outer wall of the product at the end away from the positioning hole 311 along the second direction Z. Optionally, the pusher driver 344 may include a cylinder or an electric push rod, etc.

[0091] When using the film application assembly, after the side-push film component 341 pushes the film-covering sticker onto the product, the push-moving driver 345 drives two push-drive drivers 344 to approach the positioning component 32 along the second direction Z. Then, the first push-drive driver 344 drives the first push-film component 343 to approach the second push-film component 343. The first push-film component 343 pushes the film-covering sticker on one side of the product onto the outer wall of the product along the second direction Z, away from the positioning hole 311. Then, the first push-drive driver 344 drives the first push-film component 343 to reset, and the second push-drive driver 344 drives the second push-film component 343 to approach the first push-film component 343. The second push-film component 343 pushes the film-covering sticker on the other side of the product onto the outer wall of the product along the second direction Z, away from the positioning hole 311. Finally, the second push-drive driver 344 and the push-moving driver 345 reset.

[0092] The beneficial effects of this application embodiment are as follows: the push-moving driver 345 and the push-pull driver 344 can drive the push-pull film component 343 to attach the film sticker to the outer wall of the product along the second direction Z away from the positioning hole 311. The film-coating assembly 34, through the coordinated work of the side push film component 341 and the push-pull film component 343, makes the film sticker completely attached to the product.

[0093] In some embodiments, please refer to Figures 7 to 9The positioning member 32 is provided with a clearance groove 324 that communicates with the positioning groove 321. The wrapping assembly 34 also includes a fixed driver 346 and a pressure head 347. The fixed driver 346 is connected to the pressure head 347 and is used to drive the pressure head 347 through the clearance groove 324 to hold the product in the positioning groove 321 against the groove wall of the positioning groove 321.

[0094] When the film-coating assembly 34 is in use, first control the fixed driver 346 to drive the pressure head 347 through the clearance groove 324 to hold the product in the positioning groove 321 against the groove wall of the positioning groove 321. Then control the side push driver 342 to drive the side push film component 341 to push the film-coating sticker to the outer wall of the product to prevent the product from moving during the film-coating process.

[0095] Optionally, the fixed driver 346 may include a cylinder or electric actuator connected to the frame 10.

[0096] In some embodiments, please refer to Figure 9 and Figure 10 The coating mechanism 30 also includes a pressing member 351, a connecting arm 352, an elastic member, a pushing member 361, and a pushing driver 362. One end of the connecting arm 352 along its own length direction is connected to the pressing member 351, and the other end is rotatably connected to the positioning member 32 around the third axis 353, which is perpendicular to the second direction Z. The elastic member is connected to the positioning member 32 and the connecting arm 352. The elastic member is used to drive the connecting arm 352 to hold the pressing member 351 against the groove wall of the positioning groove 321 along the second direction Z near the turntable 31.

[0097] The pusher 361 and the coating assembly 34 are spaced apart along the circumference of the turntable 31; the push driver 362 is connected to the pusher 361 and is used to drive the pusher 361 to push the connecting arm 352 along the second direction Z; the pusher 361 is located on the side of the connecting arm 352 along the second direction Z close to the turntable 31, and the pusher 361 is used to push the end of the connecting arm 352 connected to the pressing member 351 away from the positioning member 32.

[0098] When the film-coated sticker is placed in the positioning groove 321, the film-coated sticker is located on the groove wall of the positioning groove 321 near the turntable 31 along the second direction Z. The elastic element can drive the connecting arm 352 to hold the pressing member 351 against the groove wall of the positioning groove 321 near the turntable 31 along the second direction Z, preventing the film-coated sticker from moving. Optionally, the elastic element may include a tension spring or a torsion spring, etc. Optionally, the pressing member 351 may be a pressure rod or a pressure plate, etc.

[0099] The pusher 361 is located on the side of the connecting arm 352 along the second direction Z, closer to the turntable 31. When the push driver 362 drives the pusher 361 to push the connecting arm 352 along the second direction Z, the part of the connecting arm 352 in contact with the push driver 362 moves away from the turntable 31 along the second direction Z. The pusher 361 is used to push the end of the connecting arm 352 connected to the pressing member 351 away from the positioning member 32. That is, when the pusher 361 pushes the connecting arm 352, the connecting arm 352 drives the pressing member 351 away from the positioning member 32. Optionally, the pusher 361 can be a push rod or a push plate, etc. Optionally, the push driver 362 can include a cylinder or a push rod motor, etc.

[0100] The pusher 361 and the wrapping assembly 34 are spaced apart along the circumference of the turntable 31. When the turntable 31 moves the positioning member 32, the positioning member 32 moves sequentially to the positions of the pusher 361 and the wrapping assembly 34. The pusher 361 and the wrapping assembly 34 operate the wrapping sticker and the product in the positioning member 32 at different positions. The circumference of the turntable 31 is perpendicular to the second axis 331.

[0101] During the use of the coating device 100, when the turntable 31 moves the positioning member 32 to the station where the pushing member 361 is located, the push driver 362 drives the pushing member 361 to push the connecting arm 352 along the second direction Z, so that the connecting arm 352 drives the pressing member 351 away from the positioning member 32. Then, the transfer mechanism 40 moves the coating sticker into the positioning groove 321 and releases the coating sticker. The push driver 362 drives the pushing member 361 to reset. The elastic member drives the connecting arm 352 to hold the pressing member 351 against the coating sticker. The pressing member 351 holds and fixes the coating sticker to the groove wall of the positioning groove 321 along the second direction Z near the turntable 31, preventing the coating sticker from falling out of the positioning groove 321 when the turntable 31 rotates.

[0102] In some embodiments, please refer to Figure 9 A roller 354 is rotatably connected to the connecting arm 352. The rotation axis of the roller 354 is parallel to the third axis 353. The pusher 361 is used to push the roller 354, causing the roller 354 to drive the connecting arm 352 to rotate. The roller 354 can roll on the pusher 361, and the friction between the pusher 361 and the roller 354 is small.

[0103] In some embodiments, please refer to Figure 9 The coating mechanism 30 is provided with two pressing members 351, two connecting arms 352, and two elastic members. The two pressing members 351 can better fix the coating sticker. In the interval direction of the two positioning holes 311, the two pressing members 351 are respectively located on both sides of the two positioning holes 311, which can prevent the side-pushing film member 341 from interfering with the pressing members 351.

[0104] In some embodiments, please refer to Figure 2 and Figure 11 The coating device 100 also includes a product fixing member 51, a feeding conveyor belt 52, a fixing member driver 53, and a feeding driver 54. The product fixing member 51 is used to collect the product in the coating mechanism 30; the feeding conveyor belt 52 is connected to the frame 10 and is used to convey the product away from the coating mechanism 30; the fixing member driver 53 is connected to the product fixing member 51 and is used to drive the product fixing member 51 to move closer to or away from the feeding conveyor belt 52 and the coating mechanism 30 along the second direction Z; the feeding driver 54 is connected to the frame 10 and the fixing member driver 53 and is used to drive the fixing member driver 53 to reciprocate between the coating mechanism 30 and the feeding conveyor belt 52.

[0105] Optionally, the product fixing component 51 may include a gripper cylinder or an electric gripper, which can stably clamp and fix the product. Optionally, the product fixing component 51 may include a vacuum suction cup or other structure.

[0106] The fixing actuator 53 can drive the product fixing member 51 to move along the second direction Z towards the product on the wrapping mechanism 30 and the unloading conveyor belt 52, enabling the product fixing member 51 to collect and transfer the product. Optionally, the fixing member drive may include a cylinder or an electric push rod, etc.

[0107] The unloading driver 54 can drive the product fixing member 51 to reciprocate between the wrapping mechanism 30 and the unloading conveyor belt 52 via the fixing member driver 53, and can transfer the product collected by the product fixing member 51 from the wrapping mechanism 30 to the unloading conveyor belt 52. Optionally, the unloading driver 54 may include a cylinder, an electric push rod, or a linear motor, etc.

[0108] The feeding conveyor belt 52 can transport the wrapped product away from the wrapping mechanism 30, making it convenient to perform the next operation on the product.

[0109] When the coating device 100 is in use, the unloading driver 54 drives the product fixing member 51 from the unloading conveyor belt 52 to the coating mechanism 30 via the fixing member driver 53, so that the product fixing member 51 is positioned above the coated product. The fixing member driver 53 drives the product fixing member 51 to move closer to the product along the second direction Z, and then the product fixing member 51 fixes the product. The fixing member driver 53 then drives the product fixing member 51 away from the coating mechanism 30 along the second direction Z. The unloading driver 54 drives the product fixing member 51 from the coating mechanism 30 to above the unloading conveyor belt 52 via the fixing member driver 53, and then the fixing member driver 53 drives the product fixing member 51 and the product to move closer to the unloading conveyor belt 52 along the second direction Z. The product fixing member 51 releases the product, causing the product to fall onto the unloading conveyor belt 52. The unloading conveyor belt 52 then transports the coated product away from the coating mechanism 30.

[0110] The beneficial effects of this application embodiment are as follows: the unloading driver 54 and the fixing driver 53 can drive the product fixing component 51 to transfer the wrapped product in the wrapping mechanism 30 to the unloading conveyor belt 52. The unloading conveyor belt 52 can transport the wrapped product away from the wrapping mechanism 30, and the efficiency of transferring the product from the wrapping mechanism 30 to the next station is relatively high.

[0111] In some embodiments, please refer to Figure 7 The wrapping mechanism 30 also includes a visual inspection device 37, which is fixed to the frame 10. The visual inspection device 37 is located on the side of the positioning member 32 away from the turntable 31 along the second direction Z. The visual inspection device 37 is used to inspect the product in the positioning slot 321. The pusher 361, the visual inspection device 37, the wrapping assembly 34, and the product fixing member 51 for product collection are equally spaced along the circumference of the turntable 31. Four positioning members 32 are provided on the turntable 31, and the four positioning members 32 are equally spaced along the circumference of the turntable 31.

[0112] For example, the visual inspection device 37 includes a charge-coupled device camera (CCD), a light-emitting diode (LED), and an industrial control computer with visual inspection software, wherein the industrial control computer and the charge-coupled device camera are electrically connected.

[0113] During operation, the wrapping mechanism 30 controls the wrapping rotation driver 33 to rotate the turntable 31 90° each time. When the turntable 31 rotates the positioning member 32 to the pushing member 361, the transfer mechanism 40 transfers the wrapping sticker to the positioning groove 321. When the turntable 31 rotates the positioning member 32 to the vision inspection device 37, the product is placed on the wrapping sticker in the positioning groove 321. The vision inspection device 37 checks the position of the product. After the vision inspection device 37 confirms that the product is placed in the preset position, the wrapping mechanism 30 continues with subsequent actions. When the turntable 31 rotates the positioning member 32 to the wrapping assembly 34, the wrapping assembly 34 attaches the wrapping sticker to the product. When the turntable 31 rotates the positioning member 32 to the product fixing member 51, the unloading driver 54 and the fixing member driver 53 can drive the product fixing member 51 to transfer the wrapped product from the wrapping mechanism 30 to the unloading conveyor belt 52.

[0114] The visual inspection device 37 can accurately detect whether the product is placed in place, avoiding product wrapping defects caused by operator error (such as the product not being placed properly). The four positioning elements 32 allow for simultaneous operations of placing wrapping stickers, placing and inspecting products, wrapping products, and collecting products, resulting in high production efficiency.

[0115] In some embodiments, the coating device 100 further includes a controller electrically connected to the feeding mechanism 20, the coating mechanism 30, and the transfer mechanism 40, and is used to control the operation of the feeding mechanism 20, the coating mechanism 30, and the transfer mechanism 40.

[0116] Optionally, the controller may include a programmable logic controller (PLC), a microcontroller, an industrial computer, etc.

[0117] The controller can control the timing of the actions of each component in the feeding mechanism 20, the wrapping mechanism 30, and the transfer mechanism 40, realizing the automatic feeding, automatic transfer of wrapping stickers, and automatic wrapping process. The wrapping device 100 can achieve automated operation, reduce manual intervention, ensure the consistency and standardization of wrapping operations, improve production efficiency and product quality, reduce the risk of safety accidents caused by improper human operation, and provide higher safety assurance for the production process.

[0118] In some embodiments, the controller is electrically connected to the product fixing member 51, the unloading conveyor belt 52, the fixing member driver 53, and the unloading driver 54, and is able to control the automatic transfer of the product from the wrapping mechanism 30 to the next station.

[0119] In some embodiments, the coating device 100 further includes a human-machine interface (HMI) screen and sensors electrically connected to the controller. The controller is used to control the mechanical actions of the device, receive input and output signals from the sensors, and receive input and output signals from the vision inspection device 37. When the coating device 100 is started on the HMI screen, it first checks whether the feeding mechanism 20 has a roll of sticker material and whether the unloading assembly 21 is installed and ready. Then, it initializes the position and status of all drivers in the coating device 100. The vision inspection device 37 can detect whether the product is placed in place and can send a signal to the controller, which then controls the coating device 100 to perform actions. The coating device 100 is operated and controlled through the HMI screen. When the coating device 100 is started, the system automatically performs various checks and initialization tasks. Operators only need to perform simple product placement operations without complex professional skills, which lowers the operating threshold and facilitates rapid training and onboarding.

The feeding assembly 21 supports the sticker roll, which includes a backing paper and multiple coated stickers. The first platform 221 and the first guide roller 222 are arranged along a first direction X between the second guide roller 23 and the feeding assembly 21. The first guide roller 222 is connected to the first platform 221, and the first guide roller 222 and the first platform 221 are spaced apart along a second direction Z, which is perpendicular to the first direction X and the first guide roller 222. The first guide roller 222 is used to tension the sticker roll between the first platform 221 and the second guide roller 23. The platform driver 223 is connected to the first platform 221 and is used to drive the first platform 221 and the first guide roller 222 to reciprocate along the first direction X; the receiving assembly 24 is used to collect the bottom paper.

[0121] The first suction cup 251 is located on the side of the first platform 221 away from the first guide roller 222 along the second direction Z. The first suction cup 251 is used to pick up the film-coated sticker on the first platform 221. The suction cup rotation driver 252 is connected to the first suction cup 251 and is used to drive the first suction cup 251 to rotate around the first axis 224, which is parallel to the first guide roller 222. The suction cup movement driver 253 is connected to the suction cup rotation driver 252 and is used to drive the first suction cup 251 and the suction cup movement driver 253 to move closer to or away from the first platform 221 along the second direction Z.
