[0002] Invisible braces are chosen by more and more people due to their advantages such as comfort, removability and good appearance. As invisible braces are welcomed by more and more users, the demand for them is also increasing. In order to meet the growing demand for braces, it is necessary to adopt a more efficient braces packaging production model. In actual situations, the braces packaging production process will go through the processes of bag loading, labeling, bag opening, braces bagging, bag sealing, and unloading. After the corresponding processes are completed, the formed braces are packaged.

[0003] During the loading process of the packaging bag, in order to adapt to the marking process and ensure the packaging quality of the orthodontic appliance, there are certain requirements for the placement state and front and back sides of the packaging bag. The packaging bag that has been loaded must start the next process according to the predetermined placement state and predetermined surface.

[0004] In existing practical situations, the loading device picks up the packaging bag from the storage bin and transfers it, that is, the loading is completed. After the loading is completed, the placement state and the front and back sides of the packaging bag are random. In order to ensure the accuracy of packaging, manual adjustment is often required to adjust the packaging bag to a predetermined placement state and a predetermined surface. The manual input is large, time-consuming and labor-intensive, resulting in low efficiency of the entire packaging production of the orthodontic appliance. At the same time, because the placement positions of the packaging bags placed and adjusted by different people will be different, the finished packaging products of the orthodontic appliance will be different, resulting in low quality of orthodontic appliance packaging.

[0028] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. In the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0029] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0030] At present, in the loading process of orthodontic appliance packaging production, in order to ensure production accuracy, the posture of the packaging bag is manually adjusted during the subsequent packaging process. This cannot guarantee the placement state and surface accuracy of the packaging bag after loading is completed, which increases labor costs and reduces production efficiency.

[0031] Therefore, there is an urgent need to provide a feeding device for orthodontic appliance packaging bags to achieve accurate feeding of packaging bags, so as to improve production efficiency, production quality and reduce labor costs.

[0032] For the above technical issues, refer to Figures 1 to 8The utility model provides a feeding device for orthodontic appliance packaging bags, including a storage component 1, a picking component 2, a transfer adjustment component 3 and a transfer component 4. The picking component 2 picks up a target packaging bag from a plurality of packaging bags stacked on the storage component 1 and transfers the target packaging bag to the transfer adjustment component 3. The transfer adjustment component 3 can rotate the target packaging bag it carries so that the bag opening of the target packaging bag faces a predetermined direction. The transfer component 4 transfers the target packaging bag on the transfer adjustment component 3 with the bag opening facing the predetermined direction and the surface being a preset surface to the next station.

[0033] In the process of loading the packaging bag of the orthodontic appliance, the picking component 2 adopts negative pressure suction to suck the target packaging bag from the edge of the target packaging bag and transfers the target packaging bag from the storage component 1 to the transfer adjustment component 3. When the bag opening of the target packaging bag carried by the transfer adjustment component 3 faces the predetermined direction, the transfer adjustment component 3 does not need to rotate to adjust the bag opening direction. When the bag opening of the target packaging bag carried by the transfer adjustment component 3 is not facing the predetermined direction, the transfer adjustment component 3 rotates the target packaging bag it carries so that the bag opening of the target packaging bag faces the predetermined direction. The transfer component 4 also adopts negative pressure suction to suck the target packaging bag from the edge of the target packaging bag, and transfers the target packaging bag with the bag opening facing the predetermined direction and the surface being the preset surface to the next station, so that the entire loading process of the packaging bag in the orthodontic appliance packaging production is fully automated, avoiding the need for manual intervention in the packaging bag loading process, thereby improving the packaging quality of the orthodontic appliance. At the same time, since the packaging bag loading process is fully automated, the production capacity of the orthodontic appliance packaging production is significantly improved, and the defective rate in the orthodontic appliance packaging process is greatly reduced, thereby reducing the production cost of the orthodontic appliance packaging production.

[0034] refer to Figures 1 to 3 In some embodiments, the transfer adjustment component 3 includes a transfer platform 31 for carrying a packaging bag and a centering mechanism 32. The centering mechanism 32 includes a centering portion 321 and a centering drive portion 322. The centering drive portion 322 is arranged below the transfer platform 31 and can drive the centering portion 321 to move relative to the transfer platform 31. The centering portion 321 is arranged along the edge of the transfer platform 31. The centering portion 321 penetrates the transfer platform 31. A reserved space is provided on the edge of the transfer platform 31 for the centering portion 321 to pass through. One end of the centering portion 321 is higher than the bearing surface of the transfer platform 31, and the other end is lower than the bottom surface of the transfer platform 31. The centering drive portion 322 can drive the centering portion 321 to move toward the target packaging bag A on the transfer platform 31 to correct the posture of the target packaging bag A, so that the target packaging bag A is transferred to the next process in a predetermined posture to ensure the packaging quality of the orthodontic appliance.

[0035] The centering portion 321 includes multiple sub-centering portions 301, and the multiple sub-centering portions 301 are arranged opposite to each other in pairs around the edge of the target packaging bag A on the transfer platform 31. The multiple sub-centering portions 301 can move A toward the target packaging bag at the same time and respectively abut against the edge of the target packaging bag A to limit the position of the target packaging bag on the transfer platform 31.

[0036] Before the transfer assembly 4 picks up and transfers the target bag A, the sub-centering parts 301 move to a position abutting against the target bag A along a preset direction, where the preset direction is the direction of movement toward the target bag. Since each group of sub-centering parts 301 can abut against one side edge of the target bag A, the position of the target bag A on the transfer platform 31 can be adjusted to a predetermined position with the cooperation of multiple groups of sub-centering parts 301. Taking the target bag A as a square bag as an example, at least one group of relatively arranged sub-centering parts 301 can be respectively arranged in the length direction and width direction after the position of the target bag A is corrected. After the target bag A is placed on the transfer platform 31, each sub-centering part 301 moves to the target position along its own preset direction, each preset direction is perpendicular to the plane where the picking direction X is located, and the position of the target bag A is constrained in the length direction and width direction of the target bag A, and the position of the target bag A is adjusted to the preset position.

[0037] refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the picking component 2 includes a picking mechanism 21 and a flattening mechanism 22. The flattening mechanism 22 is arranged along the edge of the picking mechanism 21. When the picking mechanism 21 picks up the target packaging bag A to the transfer platform 31, the flattening mechanism 22 is arranged corresponding to the target packaging bag A on the transfer platform 31. The flattening mechanism 22 moves downward to abutment with the target packaging bag A to flatten the surface of the target packaging bag A on a horizontal plane.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the flattening mechanism 22 includes a plate-like structure 221 and a buffer structure 222 connected to the plate-like structure 221. There are multiple buffer structures 222, and the multiple buffer structures 222 are arranged along the edge of the picking mechanism 21. The plate-like structure 221 is arranged at one end of the picking mechanism 21 close to the storage component 1. The side of the plate-like structure 221 that contacts the target on the packaging bag is a flat surface, and the flat surface is parallel to the horizontal plane. There are one or more plate-like structures 221. When there are multiple plate-like mechanisms, the flat surfaces of the multiple plate-like mechanisms are at the same height.

[0039] The buffer structure 222 includes a guide portion 201 and an elastic portion 202. The elastic portion 202 is sleeved on the guide portion 201. A mounting plate 25 is provided above the picking mechanism 21. A guide hole is provided on the mounting plate 25. The guide portion 201 passes through the guide hole and is movably connected to the mounting plate 25. A limiter 203 is provided on the guide portion 201. The limiter 203 ensures that the guide portion 201 is always partially located in the guide hole. The guide portion 201 is fixedly connected to the plate-like structure 221. When the elastic portion 202 is not subjected to force, the limiter 203 contacts the mounting plate 25. When flattened, the elastic portion 202 moves in the opposite direction of the picking direction X, and the limiter 203 follows the end of the guide portion 201 away from the mounting plate 25.

[0040] In some specific cases, the picking mechanism 21 is a sponge suction cup, and the buffer structure 222 cooperates with the sponge suction cup to adapt to packaging bags of different thicknesses. The picking mechanism 21 can be set to travel the same distance in the picking direction to flatten target packaging bags of different thicknesses.

[0041] like Figure 1 and Figure 4 As shown, in some embodiments, the picking component 2 also includes a transverse movement mechanism 23 and a longitudinal movement mechanism 24, the picking mechanism 21 is used to absorb and release the target packaging bag, and the transverse movement mechanism 23 is used to move the picking mechanism 21 and the longitudinal movement mechanism 24 back and forth between the storage component 1 and the transfer platform 31, so that the picking component 2 can pick up the target packaging bag on the storage component 1 and place the target packaging bag on the transfer platform 31.

[0042] The longitudinal movement mechanism 24 is used to control the movement of the picking mechanism 21 in the picking direction, so that the picking mechanism 21 can move along the picking direction to the position of the top layer of the stacked packaging bag, absorb the target packaging bag, and drive the target packaging bag to rise in the picking direction, thereby being transferred to the position above the transfer platform 31 under the drive of the transverse movement mechanism 23, and the picked target packaging bag is placed on the transfer platform 31 under the drive of the longitudinal movement mechanism 24.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the transfer adjustment component 3 also includes a suction portion 33 disposed on the transfer platform 31. When the flattening mechanism 22 flattens the target packaging bag, the suction portion 33 sucks the target packaging bag along the edge of the target packaging bag to keep the target packaging bag in a sucked state, thereby preventing the packaging bag from sticking to the picking component 2 when the picking component 2 is away from the transfer platform 31 after flattening.

[0044] refer to Figure 1 , Figure 7 and Figure 8In some embodiments, the feeding device further includes a separation component 5 disposed on the storage component 1, and the separation component 5 separates the target packaging bag during the process of the picking component 2 picking up the packaging bag, so that the picked up target packaging bag is a single packaging bag, and the separation component 5 includes at least one group of brush structures 51 that are arranged opposite to each other and facing the stacked multiple packaging bags, and the minimum distance between the oppositely arranged brush structures 51 is smaller than the size of the packaging bag, so that when the brush structure 51 contacts the edge of the picked up packaging bag, the picked up packaging bag can bend and deform in the picking direction.

[0045] In some specific cases, the separation component 5 includes two groups of relatively arranged brush structures 51, and the two groups of brush structures 51 are arranged on opposite sides of the packaging bag. The brush structure 51 includes brushes facing the stacked multiple packaging bags and a main body connected to the brushes. The maximum length of the packaging bag along the direction opposite to the brushes is greater than the interval between the two relatively arranged brushes, so that the brush can contact at least part of the edge of the picked up packaging bag.

[0046] like Figure 1 As shown, in some embodiments, the feeding device of the orthodontic appliance packaging bag also includes a detection component 6 and a control component. The detection component 6 and the transfer adjustment component 3 are respectively communicated with the control component. The detection component 6 is arranged above the transfer adjustment component 3 and is used to detect the placement status of the target packaging bag on the transfer adjustment component 3.

[0047] In some specific cases, the detection component 6 includes a camera mechanism and a light source mechanism. The camera mechanism is used to capture the image of the packaging bag on the intermediate loading platform and transmit the image to the control component; the light source mechanism is arranged on the side of the camera component and fills the shooting area with light during shooting. The control component acquires the image and detects the placement status of the target packaging bag on the transfer adjustment component 3.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the transfer adjustment component 3 includes a rotating mechanism 34, which is used to adjust the angle of the transfer platform 31, wherein the detection component 6 can take photos to detect and provide feedback on the orientation of the packaging bag on the transfer platform 31. When the detection component 6 detects that the bag opening orientation of the target packaging bag A deviates from the predetermined orientation by an angle, the control component controls the rotating mechanism 34 to drive the target packaging bag A to rotate by the deviation angle along an axis perpendicular to the bearing surface of the transfer platform 31.

[0049] In some specific cases, the rotating mechanism 34 includes a rotating cylinder, which is arranged below the centering mechanism. The driving end of the rotating cylinder is connected to the transfer platform 31 to drive the transfer platform 31 to rotate. The rotating cylinder can drive the transfer platform 31 to rotate at any angle, and the transfer platform 31 drives the target packaging bag it carries to rotate at any angle. The rotation angle range can be set to 10 degrees to 180 degrees, for example, 10 degrees, 20 degrees, 90 degrees or 180 degrees, etc., to adapt to different deviation angles.

[0050] In some practical situations, the target packaging bag A is located on the transfer platform 31, and the detection component 6 above takes a photo to detect the bag opening direction of the placement position and provide feedback, and then the rotary cylinder rotates as needed to adjust and correct the bag opening direction of the packaging bag.

[0051] like Figure 1 and Figure 6 As shown, in some embodiments, the transfer component 4 is communicatively connected with the control component, and the transfer component 4 includes a transfer body 41 and a transfer mechanism 42, the transfer mechanism 42 is installed on the transfer body 41 and slides along the transfer body 41, and the transfer mechanism 42 is arranged above the transfer adjustment component 3, before the detection component 6 detects the bag opening direction of the target packaging bag, the detection component 6 detects whether the surface of the target packaging bag is a preset surface, wherein when the surface of the target packaging bag is the preset surface, the control component controls the transfer mechanism 42 to move a preset distance to the position of the transfer adjustment component 3 to pick up the target packaging bag, and the predetermined distance is set according to the bag opening position of the target packaging bag detected by the detection component 6.

[0052] The transfer mechanism 42 includes a plurality of suction nozzles 421 , which are arranged opposite to each other in pairs around the edge of the target packaging bag, and the plurality of suction nozzles pick up the packaging bag by negative pressure suction.

[0053] When the feeding device of the orthodontic appliance packaging bag includes a detection component 6, the target packaging bag is transferred from the storage component 1 to the transfer adjustment component 3, and the detection component 6 detects the placement state and surface of the target packaging bag on the transfer adjustment component 3 to screen out qualified target packaging bags. The control component can directly control the transfer mechanism 42 in the transfer component 4 to pick up the qualified target packaging bags screened out by the detection component 6 and transfer them to the next process, thereby improving the transfer accuracy of the target packaging bags and improving the production quality of the production line.

[0054] like Figure 1As shown, in some embodiments, the feeding device of the orthodontic appliance packaging bag also includes a collecting mechanism 7 arranged near the transfer adjustment component 3, and the collecting mechanism 7 is used to collect unqualified packaging bags. The collecting mechanism 7 is arranged on the travel path of the transfer mechanism 42 and is communicatively connected with the control component, thereby reducing the overall cost and space occupancy of the packaging bag detection equipment. When the detection component 6 detects that the surface of the target packaging bag is not the preset surface, the control component controls the transfer mechanism 42 to transfer the target packaging bag to the collecting mechanism 7, thereby ensuring the quality and consistency of the packaging of the packaging bag.

[0055] In some practical situations, the detection component 6 detects the surface of the target packaging bag on the transfer adjustment component 3 and feeds back the detection result to the control component. The control component identifies whether the surface of the target packaging bag on the transfer adjustment component 3 is the preset surface according to the detection result fed back by the detection component 6. When the surface of the target packaging bag on the transfer adjustment component 3 is the preset surface, the control component controls the transfer mechanism 42 to move a preset distance to the position of the transfer adjustment component 3 to pick up the target packaging bag. The preset distance is set according to the bag opening position of the target packaging bag detected by the detection component 6. When the surface of the packaging bag on the transfer adjustment component 3 is not the preset surface, the control component controls the transfer mechanism 42 to transfer the target packaging bag to the collection mechanism 7.

[0056] refer to Figure 1 , Figure 7 and Figure 8 In some embodiments, the storage assembly 1 includes a storage body 11, a lifting mechanism 12 and a position detection mechanism 13. The lifting mechanism 12 is arranged in the storage body 11 and can lift the stacked multiple packaging bags to the picking range along the picking direction X. The storage body 11 is provided with a picking port in the direction toward the picking assembly 2. The position detection mechanism 13 is arranged on the side of the picking port and corresponds to the picking range. When the position detection mechanism 13 detects that the stacked multiple packaging bags have reached the picking range, the picking assembly 2 picks up the packaging bags. The storage assembly 1 can be one or more to adapt to higher production efficiency.

[0057] In some specific cases, the position detection mechanism 13 is a through-beam sensor, which includes a transmitting end and a receiving end. The transmitting end emits red light or infrared light, which is received by the receiving end. When multiple stacked packaging bags pass by, the light is cut off and a signal is output.

[0058] In some practical situations, the lifting mechanism 12 includes a driving part and a carrying part. The driving part drives the carrying part to move in the picking direction. As the number of packaging bags on the carrying part gradually decreases, the position of the uppermost packaging bag will drop. The driving part drives the carrying part to move in the picking direction, so that the uppermost packaging bag on the carrying part is always within the picking range; when the carrying part needs to be reloaded with packaging bags, the driving part drives the carrying part to move in the opposite direction of the picking direction to the bottom position of the storage body 11.

[0059] The driving part can provide power for motors, cylinders, etc.

[0060] In other embodiments, the material storage component includes a material storage body and a carrying mechanism (not shown in the figure), the carrying mechanism is fixedly mounted on the material storage body, and the picking component can move to the position of the top layer of multiple packaging bags stacked on the carrying mechanism and pick up the packaging bag.

[0061] In the actual production process, the automatic guided transport vehicle automatically transfers the stacked multiple packaging bags to the lifting mechanism 12 of the storage component 1, and the lifting mechanism 12 lifts the stacked multiple packaging bags into the picking range along the picking direction. When the position detection mechanism 13 detects that the stacked multiple packaging bags have arrived in the picking range, the picking component 2 starts to pick up the packaging bags. After the picking component 2 picks up the packaging bags, it moves in the picking direction. During the movement in the picking direction, the separation component 5 on the storage component 1 separates the packaging bags that are adhered or adsorbed to each other, so that the picked packaging bags are the target packaging bags, and then the target packaging bags are transferred to the storage component 1. When it reaches the transfer platform 31, the centering drive unit 322 drives the centering unit 321 to move toward the target packaging bag on the transfer platform 31 to correct the posture of the target packaging bag. Then the picking component 2 descends again and the target packaging bag is flattened and pressed on the transfer platform 31 by the flattening mechanism 22. At this time, the suction unit 33 on the transfer platform 31 sucks the target packaging to keep the pressed target packaging bag flat. After that, the detection component 6 above the transfer platform 31 identifies the surface of the target packaging bag, the direction of the bag opening and the bag opening position. The bag opening position is the distance of the bag opening from the rotation center of the rotating platform in the horizontal direction. When it is identified that the surface of the target packaging bag is not the preset surface, the control component controls the transfer mechanism 42 to transfer the target packaging bag to the collection mechanism 7; when it is identified that the surface of the target packaging bag is the preset surface, and at the same time the bag opening direction of the target packaging bag is identified as the preset direction, or when it is identified that there is a deviation angle between the bag opening direction of the target packaging bag and the preset direction, the control component controls the rotating mechanism 34 to drive the target packaging bag to rotate along the axis perpendicular to the bearing surface of the transfer platform 31 by the deviation angle, so that the direction of the bag opening is the preset direction. Finally, the transfer mechanism 42 adjusts the path according to the bag opening position detected by the detection component 6, and the control component controls the transfer mechanism 42 to move a preset distance to the position of the transfer platform 31 to pick up the target packaging bag, and transfer the packaging bag to the next workstation.

[0062] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
