[0001] The utility model relates to the technical field of wrapping workpieces, in particular to a wrapping device. Background Art

[0002] Currently, after the product manufacturing process is completed, labels containing various product information are usually attached to products such as battery packs, mobile phones, and tablets. Generally, the label is first attached to the side wall of the product, with both ends of the label extending out of the side wall of the product. A robot or a roller connected to a cylinder is then used to push the label extending out of the side wall of the product, so that the two ends of the label are respectively attached to the top and bottom surfaces of the product, thereby wrapping the label around the side of the product. However, the pushing force applied to the label by the robot or the roller connected to the cylinder is too large, which can easily cause the label to shift, form bubbles between the label and the outside of the product, and reduce the wrapping accuracy.

[0074] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0075] See also Figure 1 The present invention provides a wrapping device 100 comprising a carrier assembly 10 and a wrapping assembly 20 for wrapping a product. The product comprises a workpiece and a small item. The small item is pre-attached to and extends beyond the lower surface of the workpiece. The workpiece may be a battery pack, and the small item may be a label containing various information about the workpiece.

[0076] For ease of understanding and explanation, Figure 1 A three-dimensional coordinate system is established in the first direction. Figure 1 The Z-axis direction shown, the second direction is Figure 1 The Y-axis direction shown, the third direction is Figure 1 The X-axis direction is shown.

[0077] See also Figure 1 、 Figure 2 and Figure 3 The carrying component 10 has a contoured groove 11 adapted to the product, and the contoured groove 11 is used to accommodate the product to push the small piece extending out of the lower surface of the workpiece to adhere to the side wall of the workpiece and extend out of the side wall of the workpiece. The wrapping assembly 20 includes a driving member 21, two sliding members 22, two pressing members 23 and two elastic members 24. The driving member 21 is connected to the supporting assembly 10. The two sliding members 22 are slidably arranged on the supporting assembly 10 and are respectively connected to the driving member 21. The two sliding members 22 move toward or away from each other under the drive of the driving member 21. The two pressing members 23 correspond to the two sliding members 22 one by one. Each pressing member 23 is respectively connected to the corresponding sliding member 22 for sliding sliding along the first direction. The two elastic members 24 correspond to the two sliding members 22 one by one. The two ends of each elastic member 24 are respectively connected to the corresponding sliding member 22 and the corresponding pressing member 23. The two pressing members 23 move toward each other under the drive of the corresponding sliding member 22 to press the small piece extending out of the side wall of the workpiece to fit it to the upper surface of the workpiece and stretch the corresponding elastic member 24.

[0078] When the above-mentioned wrapping device 100 is in operation, the supporting component 10 receives the workpiece with small parts attached to the lower surface through the profiling groove 11, so that the groove wall of the profiling groove 11 pushes the small parts extending out of the lower surface of the workpiece to be attached to the side wall of the workpiece, and the driving member 21 drives the two sliding members 22 to move toward each other, so that the two pressing members 23 press the small parts extending out of the side wall of the workpiece to fit them to the upper surface of the workpiece to complete the wrapping of the small parts to the outer periphery of the workpiece. At the same time, the two pressing members 23 stretch the corresponding elastic members 24 respectively in the process of pressing the small parts, so that the pressing force applied by the pressing members 23 to the small parts and the workpiece is moderate, avoiding excessive pressing force to damage the workpiece and small parts, or too small pressing force to make the small parts unable to fit to the workpiece, thereby achieving rapid and accurate wrapping of the small parts around the outer periphery of the workpiece, thereby improving the wrapping accuracy.

[0079] It should be noted that the wrapping area of ​​the workpiece is pre-set with a colloid to facilitate the wrapping of the small parts on the periphery of the workpiece. In other embodiments, a colloid may also be provided on the inner surface of the small parts. The number of wrapping components 20 is multiple groups, and multiple groups of wrapping components 20 are arranged at intervals around the contoured groove 11. In this embodiment, the structure of the small parts is roughly cross-shaped, and the small parts that are attached to the lower surface of the workpiece extend out of the lower surface of the workpiece along the second direction and the third direction. Therefore, the number of wrapping components 20 is correspondingly set to two groups, wherein the sliding parts 22 of one group of wrapping components 20 are slidably arranged on the supporting component 10 along the second direction, and the sliding parts 22 of the other group of wrapping components 20 are slidably arranged on the supporting component 10 along the third direction. In other embodiments, the number and arrangement of the wrapping components 20 can be adaptively adjusted according to the structure of the small parts and the workpiece, which will not be repeated here. Among them, the above-mentioned multiple groups refer to two groups and more.

[0080] See also Figure 2 In some embodiments, the driving member 21 includes a driving body 211, a driving wheel 212, a driven wheel 213 and a synchronous belt 214. The driving body 211 is arranged on the supporting assembly 10, the driving wheel 212 is connected to the driving body 211, the driven wheel 213 is spaced apart from the driving wheel 212 and is arranged on both sides of the sliding member 22 with the driving wheel 212, and the driven wheel 213 is rotatably connected to the supporting assembly 10. The synchronous belt 214 is sleeved on the driving wheel 212 and the driven wheel 213, and the synchronous belt 214 is respectively connected to the two sliding members 22. Under the drive of the driving wheel 212 and the driven wheel 213, the synchronous belt 214 drives the two sliding members 22 to move toward or away from each other. Exemplarily, the driving body 211 can be a rotary motor.

[0081] In this way, by setting the specific structure of the driving member 21, the driving body 211, the driving wheel 212, the driven wheel 213 and the synchronous belt 214 can form a belt transmission mechanism, so that the driving member 21 can utilize the smooth transmission characteristics of the belt transmission mechanism, so that the driving member 21 can stably drive the two sliding members 22 to move toward or away from each other synchronously, thereby improving the driving stability.

[0082] See also Figure 2 In some embodiments, the sliding member 22 includes a sliding body 221, a supporting body 222, and a connecting body 223. The sliding body 221 is slidably connected to the carrier assembly 10, and the side of the sliding body 221 facing away from the carrier assembly 10 is connected to the corresponding elastic member 24. The supporting body 222 and the corresponding elastic member 24 are spaced apart from each other on the sliding body 221. The supporting body 222 is slidably connected to the pressing member 23 along a first direction. The connecting body 223 is protruding from the outer side of the sliding body 221 and is detachably connected to the synchronous belt 214. Driven by the synchronous belt 214, the connecting body 223 drives the sliding body 221 and the supporting body 222 to move synchronously.

[0083] Thus, by providing the sliding body 221 in sliding connection with the bearing assembly 10 and the connecting body 223 in sliding connection with the corresponding pressing member 23, the sliding member 22 can be rationally arranged. In addition, by providing the connecting body 223 with the synchronous belt 214 in a detachable connection, it is convenient for the operator to install the sliding body 221 to the synchronous belt 214, so that the synchronous belt 214 can stably drive the pressing member 23 to move synchronously through the connecting body 223.

[0084] See also Figure 2 and Figure 3 In some embodiments, the sliding member 22 further includes a limiting body 224, which is arranged on the sliding body 221 and movably penetrates the corresponding pressing member 23. A limiting portion 2241 is protruded from the outer side of the limiting body 224, and the limiting portion 2241 is located between the pressing member 23 and the sliding body 221. The limiting portion 2241 is used to support the pressing member 23 toward the side of the sliding body 221.

[0085] In this way, after the wrapping device 100 completes the wrapping operation, the pressing member 23 and the workpiece are first loosened from each other, and the stretched elastic member 24 drives the pressing member 23 to reset, and then the limiting portion 2241 is pressed against the side of the pressing member 23 facing the sliding body 221, so that the limiting portion 2241 limits the reset position of the pressing member 23, so that the pressing member 23 is stably and accurately reset to the initial position, which facilitates the wrapping device 100 to repeat the wrapping operation.

[0086] See also Figure 3In some embodiments, the wrapping assembly 20 further includes a first detecting member 25 and a second detecting member 26. The first detecting member 25 and the second detecting member 26 are spaced apart and arranged on one side of the sliding body 221 along the movement direction of the corresponding sliding member 22. The first detecting member 25 and the second detecting member 26 are both electrically connected to the corresponding driving body 211. The first detecting member 25 is located adjacent to the outer side of the carrier assembly 10 relative to the second detecting member 26. The first detecting member 25 and the second detecting member 26 are used to detect the movement position of the sliding body 221. For example, the first detecting member 25 and the second detecting member 26 can both be photoelectric sensors, position sensors, etc.

[0087] In this way, the moving position of the sliding body 221 is detected by the first detection member 25 and the second detection member 26 during the movement of the sliding body 221. When the first detection member 25 detects the sliding body 221, the first detection member 25 sends an electrical signal to the driving body 211, and the driving body 211 stops running based on the detection information of the first detection member 25, so that the sliding body 221 is accurately reset to the initial position. When the second detection member 26 detects the sliding body 221, the second detection member 26 sends an electrical signal to the driving body 211, and the driving body 211 stops running based on the detection information of the second detection member 26, so as to avoid the sliding body 221 from moving too far and causing a collision between the components of the wrapping component 20 and the supporting component 10.

[0088] See also Figure 2 In some embodiments, the pressing member 23 includes a movable body 231, a linkage body 232, and a pressing body 233. The movable body 231 is slidably connected to the support body 222 along a first direction. The linkage body 232 is mounted above the supporting assembly 10 and connected to the movable body 231. The pressing body 233 is detachably connected to the linkage body 232. Driven by the movable body 231, the pressing body 233 presses the small piece against the upper surface of the workpiece.

[0089] Thus, by arranging the linkage body 232 above the carrier assembly 10 and connecting it to the movable body 231, the pressing member 23 can be arranged in a reasonable manner. In addition, by arranging the pressing member 233 and the linkage body 232 to be detachably connected, the operator can easily adjust the installation position of the pressing member 233 according to the wrapping area of ​​the workpiece, so that the pressing member 233 can accurately press the small workpiece to the predetermined area of ​​the workpiece.

[0090] Please continue reading Figure 2 In some embodiments, the pressing body 233 includes a mounting portion 2331 and a rolling portion 2332. The mounting portion 2331 is detachably connected to the linkage body 232. A mounting groove 2331a is provided on the side of the mounting portion 2331 away from the linkage body 232. The rolling portion 2332 is disposed in the mounting groove 2331a and is rotatably connected to the mounting portion 2331. The rolling portion 2332 is used to roll against the small item.

[0091] In this way, by setting the rolling part 2332 and the mounting part 2331 to be rotatably connected, when the rolling part 2332 is driven by the mounting part 2331 to press the small part to the upper surface of the workpiece, rolling contact is formed between the rolling part 2332 and the small part, thereby preventing the small part from being damaged during the wrapping process.

[0092] See also Figure 1 In some embodiments, the carrier assembly 10 includes a carrier 12, a base 13, and a plurality of support members 14. The carrier 12 is provided with a contoured groove 11 for supporting a workpiece. The base 13 and the carrier 12 are spaced apart along a first direction, forming a storage space 131 between the base 13 and the carrier 12. The storage space 131 stores the package assembly 20. The plurality of support members 14 are spaced apart between the carrier 12 and the base 13, and each support member 14 is connected to the carrier 12 and the base 13, respectively.

[0093] In this way, by setting the specific structure of the above-mentioned carrying component 10, the storage space 131 can store the wrapping component 20, so that the wrapping device 100 has a reasonable layout.

[0094] See also Figure 4 In some embodiments, the carrier 12 defines two avoidance holes 121, which correspond one-to-one with the two pressure members 23 of the wrapping assembly 20. The avoidance holes 121 are used to receive the pressure members 23. In this embodiment, there are four avoidance holes 121, which correspond one-to-one with the four pressure members 23 of the two sets of wrapping assemblies 20.

[0095] In this way, by setting two avoidance holes 121 corresponding one to one with the two pressure members 23 of the wrapping assembly 20, the avoidance holes 121 can accommodate the pressure members 23 during the wrapping process of the wrapping device 100, thereby avoiding the pressure members 23 and avoiding collision between the wrapping assembly 20 and the carrier 12.

[0096] Please continue reading Figure 4 In some embodiments, the carrier assembly 10 further includes a third detection member 15, which is embedded in the bottom of the contoured groove 11 and connected to the carrier 12. The third detection member 15 is electrically connected to the driving member 21. For example, the third detection member 15 can be a photoelectric sensor, a position sensor, etc.

[0097] In this way, by setting the above-mentioned third detection member 15 to detect whether the workpiece is placed on the carrier 12, when the third detection member 15 detects that the workpiece has been placed on the carrier 12, the third detection member 15 sends an electrical signal to the driving body 211 of the wrapping component 20, so that the driving body 211 drives the two sliding bodies 221 to move toward each other based on the detection information of the third detection member 15.

[0098] The working process of the above-mentioned wrapping device 100 is roughly as follows:

[0099] First, the workpiece drives the small piece attached to the lower surface of the workpiece to be placed in the contoured groove 11 of the carrier 12. The small piece extending out of the lower surface of the workpiece is supported by the groove wall of the contoured groove 111 and adheres to the side wall of the workpiece and extends out of the side wall. When the third detection member 15 detects that the workpiece has been placed on the carrier 12, the third detection member 15 sends an electrical signal to the driving body 211 of the wrapping assembly 20.

[0100] Then, the driving body 211 drives the driving wheel 212 to drive the synchronous belt 214 and the driven wheel 213 to rotate synchronously along the preset direction, so that the two sliding members 22 of the wrapping assembly 20 move toward each other, so that the two pressing members 23 press the small piece extending from the side wall of the workpiece to fit it to the upper surface of the workpiece to complete the wrapping of the small piece to the outer periphery of the workpiece. At the same time, the two pressing members 23 respectively stretch the corresponding elastic members 24 when pressing the small piece, so that the pressing force applied by the pressing members 23 to the small piece and the workpiece is moderate, avoiding excessive pressing force to damage the workpiece and the small piece, or too little pressing force to make the small piece unable to fit to the workpiece, thereby achieving rapid and accurate wrapping around the outer periphery of the workpiece, thereby improving the wrapping accuracy.

[0101] Finally, the driving body 211 drives the active wheel 212 to drive the synchronous belt 214 and the driven wheel 213 to rotate synchronously in the opposite direction of the preset direction, so that the two sliding parts 22 of each group of wrapping components 20 move in opposite directions, so that the pressing part 23 loosens the wrapped workpiece, making it easier to remove the workpiece.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
