Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of manufacturing dental films, and in particular to a feeding device for dental films. Background Art

[0002] The production of invisible braces generally includes the processes of dental model printing, dental model cleaning, dental model curing, molding, demoulding, cutting, cleaning, inspection, packaging, etc. Among them, in the production process of invisible braces, the diaphragm is an especially important raw material in the preparation of invisible braces.

[0003] As the demand for invisible braces increases day by day, the demand for diaphragms also increases greatly. The production process of diaphragms includes at least extrusion, cutting, inspection, packaging and other processes. Sheets are the raw materials for diaphragm preparation. In the production process of diaphragms, sheet cutting is an indispensable part, which directly affects the quality of diaphragms. The cutting process of diaphragms mainly includes loading, cutting and discharging. Sheets are generally stored in stacks of multiple sheets. Due to static electricity and pressure factors, the stacked multiple sheets are easy to stick to each other. When loading, the loading device picks up the sheets from the stacked multiple sheets. When picking up, it often picks up multiple sheets that stick to each other at one time and feeds multiple sheets to the diaphragm production line. If multiple sheets are cut, defective products will be produced, which seriously affects the production quality of the diaphragm. Due to the high cutting precision requirements of diaphragms, in order to ensure the production quality of diaphragms, only one sheet is cut at a time on the diaphragm production line to form multiple diaphragms, which requires that the diaphragms that are fed can only be single sheets. In the prior art, when a picking device picks up multiple sheets that are stuck together, manual intervention is required to separate the stuck sheets so that the final sheet picked up is a single sheet and the single sheet is cut, which results in low production efficiency and unnecessary manpower consumption.

For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

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".

[0032] As can be seen from the background technology, the sheet separation of the current sheet feeding device is still manually operated, which has the problems of low automation, low production efficiency and high production cost.

[0033] In order to realize the automation of sheet separation in the feeding device and improve production efficiency, the embodiment of the present application provides a feeding device for dental sheets. Through the setting of the peeling component, when the picking component picks up the sheet, the peeling component and the picking component work together to realize the automated separation of the adhered sheets.

[0034] refer to Figures 1 to 11, a feeding device for dental sheets provided in an embodiment of the present application comprises: a material storage component 1, a picking component 2 and a stripping component 3; the material storage component 1 comprises a material storage bin 11 and a carrying platform 12 arranged in the material storage bin 11, the material storage bin 11 is used to store a plurality of stacked sheets C, and the carrying platform 12 is used to carry the plurality of stacked sheets C in the material storage bin 11; the picking component 2 is arranged above the carrying platform 12, and the picking component 2 is used to pick up the sheets on the carrying platform 12; the stripping component 3 is arranged on the material storage component 1, and the stripping component 3 is used to separate the sheets picked up by the picking component 2 so that the final sheet picked up is a single sheet. The stripping component 3 comprises a stripping structure 31 protruding toward the area where the plurality of stacked sheets C are located and arranged relatively, the stripping structure 31 is arranged above the plurality of stacked sheets C, and a stripping area is formed between the stripping structures 31 arranged relatively; wherein, when the picking component 2 picks up the sheet, it can perform at least one stripping in the stripping area in the picking direction ( Figure 1 The stripping structure 31 reciprocates in the direction indicated by the arrow X in the middle, and when the stripping structure 31 contacts the edge of the picked-up sheet, the picked-up sheet undergoes two bending deformations in different directions, so that the adhered sheets are separated.

[0035] The stripping assembly 3 is provided in the feeding device of the dental sheet. When the picking assembly 2 picks up the sheet, the picking assembly 2 drives the picked-up sheet to move upward and downward along the picking direction. Figure 3 As shown, when moving upward along the picking direction, that is, along the picking direction X, the edges of the opposite sides of the picked sheet contact the peeling structure 31, and the picked sheet P can form a parabolic surface with an opening facing downward, so that at least part of the surface of the sheet located on the top layer of the picked sheet P is separated from the adjacent adhered sheets, and the adsorption capacity between the sheet on the top layer and the adjacent adhered sheets due to factors such as atmospheric pressure or friction will be effectively reduced, so that the sheet on the top layer is completely separated from the adhered sheets, so that the final sheet picked up is a single sheet, as shown in FIG. Figure 4 As shown, when continuing to move downward in the picking direction, that is, in the opposite direction Y of the picking direction, the edges on the opposite sides of the picked sheet P contact the stripping structure 31 again, and the picked sheet P can form a parabolic surface opening upward, so that at least part of the surface of the sheet located on the top layer of the picked sheet P is separated from the adjacent adhered sheets again, so as to separate the adhered sheets again, further increasing the probability that the final sheet picked up is a single sheet, thereby ensuring that the loaded sheet is a single sheet and controlling the production accuracy of the dental membrane.

[0036] like Figures 5 to 9As shown, the stripping structure 31 includes a plurality of tip structures 311 arranged along the picking direction X in the stripping area, one end of the tip structure 311 facing the stacked multiple sheets C is a tip, and the other end of the tip structure 311 opposite to the tip is connected to the main body of the stripping structure 31, and the width of the tip structure 311 in the picking direction X gradually decreases as the distance between itself and the main body increases. The tip is in the shape of a sharp ridge or a spike to reduce the contact area with the sheet when it abuts against the picked sheet, so as to prevent the picked sheet from adhering to the tip structure 311. The plurality of tip structures 311 provided in the stripping structure 31 can be arranged continuously or at intervals. The minimum distance L1 between the two oppositely arranged tip structures 311 is less than the size L2 of the sheet, that is, the maximum length L2 of the sheet in the direction opposite to the tip structures 311 is greater than the interval L1 between the two oppositely arranged tip structures 311, so that the tip structure 311 can contact at least part of the edge of the picked sheet. The number of the tip structures 311 can be adjusted according to specific needs and is not limited here.

[0037] Combined with reference Figures 5 to 7 In some embodiments, in a direction perpendicular to the picking direction ( Figure 1 In the direction indicated by the middle arrow S), the minimum distances between the relatively arranged tip structures 311 are equal, that is, the interval L1 between each pair of relatively arranged tip structures 311 is equal. When the picking component 2 picks up the sheet and moves along the picking direction X, the contact points of each pair of tip structures 311 and the picked sheet can maintain synchronization, ensuring the stable output of the force applied by the tip structure 311 to the edge of the picked sheet and the smooth progress of the peeling process.

[0038] In other embodiments, in the direction S perpendicular to the picking direction, the minimum distance between the relatively arranged tip structures 311 may also be unequal, that is, in the direction S perpendicular to the picking direction, the minimum distance between the relatively arranged tip structures 311 may gradually decrease along the picking direction X, and the minimum distance between the relatively arranged tip structures 311 may also gradually increase along the picking direction X.

[0039] like Figure 8 and Fig. 9 As shown, in the direction S perpendicular to the picking direction, when the minimum distance between the relatively arranged tip structures 311 gradually decreases along the picking direction X, that is, the interval between the two relatively arranged tip structures 311 gradually decreases, when the picking component 2 picks up the sheet along the picking direction X and moves in the stripping area, the force applied by the tip structure 311 to the edge of the picked sheet gradually increases, and the deformation of the picked sheet also gradually increases, thereby improving the separation effect of the stripping component 3 on the picked sheet.

[0040] In addition, in the direction S perpendicular to the picking direction, the minimum distance between the oppositely arranged tip structures 311 may also increase or decrease in a step-by-step manner along the picking direction X (not shown in the figure).

[0041] In some embodiments, the tip structure 311 is tilted toward the picking surface of the stacked multiple sheets C, that is, the tip can be tilted downward toward the picking surface of the stacked multiple sheets C, or the tip can be tilted upward toward the picking surface of the stacked multiple sheets C.

[0042] like Figure 7 and Fig. 9 As shown, when the tip is tilted downward toward the picking surface of the stacked multiple sheets C, the tip structure 311 can first guide the picked sheets to move tilted downward, and then the picked sheets suddenly turn, which is more conducive to the separation of the picked sheets.

[0043] refer to Figure 5 , Figure 6 and Figure 8 In other embodiments, the tip structure 311 is arranged in parallel with the picking surface of the stacked multiple sheets C, that is, the tips of the relatively arranged tip structures 311 are located on the same straight line and in opposite directions, so that the tip structure 311 first guides the edge of the picked sheet to move upward or downward, and then the picked sheet turns smoothly, preventing the turning force of the picked sheet from being too large, thereby reducing damage to the edge of the picked sheet.

[0044] like Figure 1 As shown, the picking assembly 2 includes a picking part, a motion module and a driving part, the driving part drives the motion module to move, and the motion module drives the picking part to move to a position above the stacked multiple sheets C and pick up the sheets. The driving part can be a component that provides power for a motor, a cylinder, etc.

[0045] In some specific cases, the picking part includes a plurality of suction nozzles arranged along the edge of the sheet, and the suction nozzles suck the sheet by negative pressure suction. The motion module includes a transverse moving part and a vertical moving part. The transverse moving part is used to drive the picking part and the vertical moving part to move in the horizontal direction, while the vertical moving part is used to control the movement of the suction part in the picking direction X, so that the suction part can move along the picking direction to the position of the top sheet of the stacked multiple sheets, pick up the sheet, and drive the picked sheet to rise in the picking direction, thereby transferring the picked sheet under the drive of the transverse moving module. The horizontal moving part can be a rotatable component such as a drag chain or a tank chain. The vertical moving part can be a component that slides with each other such as a slide groove and a slide rail.

[0046] That is to say, the picking component 2 can drive the picked sheet to perform upward and downward reciprocating motion in the picking direction X through the vertical moving part. In the process of picking up the sheet, the picking component 2 makes the picked sheet perform at least one upward and downward reciprocating motion along the picking direction X between the relatively arranged peeling structures 31, so that the picked sheet can undergo two bending deformations in different directions during this process. The two deformations in different directions are used to further increase the probability of separation between the picked sheet and the adjacent adhered sheets.

[0047] In some embodiments, the speed range of the picking component 2 in the peeling area is 100mm / s to 300mm / s. The selection of this speed range can ensure that the picking component 2 can achieve good separation of the adhered sheets in the process of picking up the sheets, and further increase the probability that the final sheet picked up is a single sheet.

[0048] refer to Figure 1 , Fig.10 and Fig.11 In some embodiments, the feeding device for dental sheets further comprises a blowing assembly 4, wherein the blowing assembly 4 comprises a blowing structure 41 arranged on the same side as the peeling structure 31, wherein when the picking assembly 2 drives the picked sheet to move in the peeling area, the blowing structure 41 blows gas toward the edge of the picked sheet, and the air flow range blown by the blowing structure 41 at least covers the peeling structure 31 in the peeling area in the picking direction X.

[0049] The final number of sheets picked up by the picking component 2 is preferably a single piece, and the main factor affecting the final number of sheets picked up is the adhesion between the sheets. Therefore, on the basis of setting a peeling structure 31 on the storage component 1 to peel off the picked up sheets, a corresponding blowing structure 41 can also be set on the side where each peeling structure 31 is located. The position setting of the blowing structure 41 can be similar to the position setting of the peeling structure 31, that is, the blowing structure 41 is relatively arranged on both sides of the stacked multiple sheets C, and is located above the stacked multiple sheets C. In addition, the gas blowing direction of the blowing structure 41 can also be directed toward the edge of the picked up sheet. During the process of the picking component 2 picking up the sheet, when the picking component 2 drives the picked up sheet to move in the peeling area, the blowing component 4 blows gas to the edge of the picked up sheet, and then uses the flow of gas to reduce the probability of the picked up sheet coming into contact with the adjacent adhering sheets again, thereby further reducing the difficulty of separating the picked up sheet from the adjacent adhering sheets, and increasing the probability that the final sheet picked up each time is a single sheet.

[0050] The purpose of the air blowing by the air blowing component 4 is to improve the separation between the picked-up sheet and the adjacent adhered sheet, so that the final sheet picked up at a time is as single-piece as possible, and the peeling structure 31 is to make the edge of the picked-up sheet have at least a part of the area not in contact with the adjacent adhered sheet. In order to further improve the effect of the air blowing component 4 in assisting the separation of sheets, it is necessary to blow the air flow between the two adjacent sheets as much as possible. Therefore, the air outlet direction of the air blowing component 4 can be set so that the airflow blown by the air blowing component 4 can at least cover the peeling structure 31 in the peeling area in the picking direction X, and then the airflow can be effectively conducted along the peeling structure 31 to the adjacent sheets, effectively assisting the separation between the picked-up sheets.

[0051] In some specific cases, the blowing structure 41 includes an air supply pipe and a pressure supply member, one end of the air supply pipe is connected to the pressure supply member, and the other end is located above the stacked multiple sheets C. The air supply pipe is set toward the peeling area, and the pressure supply member is a device for supplying positive pressure. The pressure supply member can blow gas through the ventilation pipe to the edge of the picked sheet.

[0052] In some embodiments, the pressure of the blowing component 4 is set within a predetermined range, which is 0.2Mpa to 0.5Mpa. The setting of the predetermined range can provide a strong wind force to blow between the top sheet and the adjacent bonded sheet where the sheet is separated, so that the adsorption force between the top sheet and the adjacent bonded sheet is further reduced, thereby improving the separation effect of the bonded sheet.

[0053] refer to Figure 1 and Figure 2 In some embodiments, the storage assembly 1 further includes a storage body 13, which provides a mounting and fixing foundation for other parts, and the carrying platform 12 is mounted on the storage body 13. The storage bin 11 includes a limit portion 111 and a limit adjustment portion 112, which are arranged along the edge of the sheet, and the limit portion 111 and the limit adjustment portion 112 are enclosed to form a sheet accommodating space, which constrains the stacked multiple sheets C in the length direction and the width direction, and the limit adjustment portion 112 can adjust the size of the sheet accommodating space to adapt to sheets of different sizes. The storage body 13 is formed with an opening above one side of the limit adjustment portion 112, and the picking assembly 2 extends into the storage bin 11 through the opening to pick up the sheet. Since the sheet material is usually square, the sheet material accommodating space formed by the limiting portion 111 and the limiting adjustment portion 112 in this embodiment is also square. Of course, in other embodiments, the sheet material accommodating space may also be circular, which is not limited here.

[0054] In some specific cases, the limiting portion 111 includes a plurality of limiting columns, which are arranged around the supporting platform 12, one end of the limiting column is connected to the material storage body 13, and the other end is extended toward the supporting platform 12, the limiting adjustment portion 112 includes a limiting plate 101 and a driving cylinder 102, the driving cylinder 102 is fixedly mounted on the material storage body 13, the output end of the driving cylinder 102 is connected to the limiting plate 101, and can drive the limiting plate 101 to move in a direction perpendicular to the picking direction X to adjust the spacing distance between the limiting plate 101 and the limiting column arranged opposite to it to adapt to sheets of different widths. Taking the case where the lengths of sheet A and sheet B are the same and the width of sheet A is smaller than the width of sheet B as an example, the sheet currently carried by the carrying platform 12 is sheet A with a smaller width. When the sheet is adjusted to sheet B with a larger width, the limiting plate 101 is driven by the driving cylinder 102 to move in a direction away from the stacked multiple sheets C, increasing the spacing between the limiting plate 101 and the limiting columns arranged opposite thereto to adapt to the width of sheet B. The limiting adjustment part 112 can further improve the adaptability of the dental sheet feeding device to different sheets. The number of limiting columns can be set according to specific needs and is not limited here.

[0055] refer to Figure 1 and Figure 2 In some embodiments, the carrying platform 12 can be movably installed on the material storage component 1, and the carrying platform 12 can move along the picking direction X to transport the stacked multiple sheets C it carries to a predetermined area, and the picking part of the picking component 2 can move to the predetermined area and pick up the sheets.

[0056] In some specific cases, the loading device of the dental sheet material further includes a bearing driving device 5, which drives the bearing platform 12 to move along the picking direction X. The bearing platform 12 includes a bearing portion 121 and a mounting portion 122, wherein the bearing portion 121 is fixedly arranged on the mounting portion 122, and the mounting portion 122 is connected to the material storage body 13. The mounting portion 122 includes a bearing 123 arranged opposite to each other, and a guide rod 124 matching the bearing 123 is arranged on the material storage body 13, and the guide rod 124 passes through the sliding hole of the bearing 123, and the bearing 123 moves along the guide rod 124 to ensure that the uppermost sheet on the bearing portion 121 can be moved to a predetermined area, and the arrangement of the bearing 123 can also provide guidance for the bearing portion 121, while balancing the unbalanced load and reducing the friction. As the number of sheets on the carrying portion 121 gradually decreases, the position of the sheets at the top will drop, and the carrying platform 12 will be driven to move along the picking direction X by the carrying driving device 5, so that the sheets at the top of the carrying platform 12 are always within the predetermined area; when the carrying portion 121 needs to be reloaded with sheets, the carrying driving device 5 will drive the carrying portion 121 to move in the opposite direction of the picking direction X to the bottom position of the storage bin 11.

[0057] In addition, the mounting portion 122 may also include a linear guide rail (not shown) arranged relatively, a slide bar matching the linear guide rail is provided on the material storage body 13, a slider matching the linear guide rail is provided on the slide bar, and the linear guide rail moves along the slide bar to ensure that the uppermost sheet on the bearing portion 121 can be moved to a predetermined area. The specific structural form of the mounting portion 122 and the sliding connection mode with the material storage body 13 may also adopt other embodiments, which are not limited here.

[0058] Among them, Figure 1 and Figure 2 As shown, the bearing drive device 5 includes a driving source 51 and a transmission mechanism 52. The driving source 51 drives the transmission mechanism 52 to move, and the transmission mechanism 52 drives the bearing platform 12 to move up and down. The driving source 51 can be a component that provides power for a motor, a cylinder, etc., and the transmission mechanism 52 can be a gear rack drive, a belt drive, or a chain drive.

[0059] In other embodiments, the carrying platform is fixedly mounted on a material storage assembly (not shown in the figure), the carrying platform includes a carrying portion and a mounting portion, the mounting portion is fixedly connected to the material storage body, the carrying portion is fixedly connected to the mounting portion, and the picking assembly can move to the position of the top layer of multiple sheets stacked on the carrying portion and pick up the sheets.

[0060] 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.
