Description

Technical Field

[0001] The utility model relates to the technical field of dental appliance production, in particular to a diaphragm stop component and a diaphragm transport device. Background Art

[0002] Shell-shaped dental appliances are chosen by more and more people due to their advantages such as being comfortable to wear, removable and beautiful. Shell-shaped dental appliances are generally made of flat diaphragms of certain specifications through a hot pressing process. As the raw material for the production of shell-shaped dental appliances, the diaphragm involves the transportation and transfer of the diaphragm during the entire production process of the shell-shaped dental appliances, and precise positioning is required during the transportation and transfer process. However, due to the different sizes of dental models and different product specifications, the specifications of the diaphragm used in production will change according to the changes in the size of the dental model and the product specifications.

[0003] The diaphragms used to produce shell-shaped dental appliances usually have a variety of specifications, such as a round diaphragm with a diameter of 130mm, a round diaphragm with a diameter of 110mm, a square diaphragm with a side length of 100mm, etc. During the transportation and stopping of the diaphragms, there are difficulties in the transportation and stopping of different diaphragms in the process of the same conveyor line being adapted to the transportation of diaphragms of different specifications. Specifically, generally a stopping mechanism only stops diaphragms of one specification, that is, a stopping mechanism is adapted to diaphragms of one specification. When stopping a diaphragm of another specification, the current stopping mechanism needs to be removed from the conveyor line and reinstalled to adapt to a diaphragm of another specification. Moreover, the stopping mechanism can only stop the diaphragm in the conveying direction, and there is no restriction on other directions of the diaphragm, and it is impossible to achieve accurate positioning of the diaphragm. At the same time, when the conveyor line conveys diaphragms of different specifications, it is necessary to adjust the width of the conveyor line by adjusting the stopping parts on both sides of the conveyor belt so that the width between the conveyor lines is adapted to the size of the conveyed diaphragm. When diaphragms of different specifications need to be transported and stopped on the conveyor line, it is necessary to replace the stop mechanism and adjust the stop parts on both sides of the conveyor belt, which is time-consuming and labor-intensive and has low production efficiency.

[0039] 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.

[0040] 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".

[0041] Example 1

[0042] See also Figure 1-Figure 10 The present embodiment provides a diaphragm stop assembly, which includes a stop body 1 and a lifting mechanism 2. The lifting mechanism 2 is connected to one side of the stop body 1, and the lifting mechanism 2 can drive the stop body 1 to reciprocate up and down along the lifting direction S.

[0043] The stopping body 1 includes a base 11, a stopping portion 12 and a limiting portion 13. One side of the base 11 is fixedly connected to the lifting mechanism 2, and the other side is extended in the lifting direction S to be provided with a stopping portion 12 and a limiting portion 13. The stopping portion 12 stops the diaphragm A in the conveying direction X and limits the diaphragm A from continuing to move forward along the conveying direction X, and the limiting portion 13 guides the diaphragm A into the stopping body 1.

[0044] The lifting mechanism 2 includes a connecting member 22 and a driving member 23. One end of the connecting member 22 is movably connected to the driving member 23, and the other end is fixedly connected to the base 11. The driving member 23 drives the connecting member 22 to make the connecting member 22 reciprocate up and down, thereby driving the stop body 1 to reciprocate up and down. The driving member 23 can be a cylinder, a motor, etc.

[0045] Among them, Figure 1 , Figure 4 and Figure 5 As shown, the stopping portion 12 is provided with a plurality of positioning slots in sequence along the lifting direction S on one side facing the diaphragm A, and the limiting portion 13 is provided with a plurality of limiting slots corresponding to the plurality of positioning slots in sequence along the lifting direction S on one side facing the diaphragm A. The number of the positioning slots 121 may be 2, 3 or more, and the specific number is designed according to production requirements, and the number of limiting slots 131 is consistent with the number of the positioning slots 121. In the corresponding positioning slots 121 and limiting slots 131, the heights of the positioning slots 121 and the limiting slots 131 are the same, the diaphragm stopped by the positioning slots 121 and the diaphragm guided by the limiting slots 131 are the same diaphragm, the shape of the positioning slots 121 matches the shape of the portion that is abutted after the diaphragm reaches the predetermined position, and the shape of the limiting slots 131 matches the shape of the portion that is held after the diaphragm reaches the predetermined position. The corresponding positioning slots 121 and limiting slots 131 enclose a diaphragm accommodating space B (such as Figure 4The space enclosed by the dotted frame M in the middle), the diaphragm accommodating space B can accommodate a diaphragm located at a predetermined position, and a diaphragm accommodating space can accommodate a diaphragm of one specification. Thus, the positioning slots arranged in sequence and the corresponding limiting slots are enclosed to form a plurality of diaphragm accommodating spaces arranged in sequence along the lifting direction S. The plurality of diaphragm accommodating spaces arranged in sequence can respectively accommodate diaphragms of different specifications, and the size of any adjacent diaphragm accommodating spaces satisfies: the diaphragm accommodated in the lower diaphragm accommodating space can freely pass through the upper diaphragm accommodating space along the lifting direction S, thereby realizing a diaphragm stop assembly that can stop diaphragms of different specifications. The plurality of diaphragm accommodating spaces arranged in sequence on the stop body can make it possible to stop diaphragms of different specifications without replacing other components, and only the lifting mechanism 2 needs to lift the stop body 1 to the specified position, so that the diaphragm accommodating space is adapted to the diaphragm that currently needs to be stopped on the production line, thereby reducing production costs and improving production efficiency. It should be noted that diaphragms of different specifications refer to diaphragms of different shapes, different sizes, different thicknesses or different materials, or a combination of any two or more thereof. For example, it can be a 100 mm square diaphragm, a 115 mm circular diaphragm, and a 130 mm circular diaphragm, etc. The specific specifications of the diaphragm are set according to actual production requirements, and this embodiment does not limit them.

[0046] Furthermore, if Figure 4 As shown, the limiting parts 13 are arranged on both sides of the stop part 12, and the limiting parts 13 on both sides are arranged relatively, the stop part 12 limits the continued movement of the diaphragm in the conveying direction X, and the limiting parts 13 limit the movement of the diaphragm in the preset direction Y, and the preset direction Y is a direction perpendicular to the conveying direction X and the lifting direction S, respectively, so as to achieve accurate positioning of the diaphragm. It should be noted that the limiting parts 13 can include 2, 4 or more, and the specific number can be determined according to the specific production situation, and this embodiment does not limit it.

[0047] In some embodiments, there are multiple limiting parts on each side (not shown in the figure), the number of the multiple limiting parts on both sides is the same, the multiple limiting parts on both sides are respectively arranged opposite to each other, and the multiple limiting parts on each side are arranged at intervals. When the limiting parts on both sides are arranged at intervals, materials can be saved and the space occupied by the base can be reduced.

[0048] In some other embodiments, there is a limit portion on each side, such as Figure 1 As shown, the limiting parts include two, one limiting part 13 is arranged on each side of the stop part 12, and the limiting parts 13 on both sides are arranged oppositely. When the limiting parts on both sides are arranged continuously, the process is simple and can play a better guiding role on the diaphragm.

[0049] Furthermore, the limiting parts 13 on both sides can be axisymmetric or center-symmetrical. Figure 1As shown, the limiting portion 13 is symmetrically arranged relative to the stopping portion 12, that is, the cross-sectional center line of the stopping portion 12 on the plane where the conveying direction X is located is taken as the symmetry axis; in the case of central symmetry, the center of the base 11 is taken as the symmetry center. The limiting portions 13 on both sides are symmetrically arranged, which can play a role in more accurate positioning and better guiding of the diaphragm.

[0050] In some embodiments, the plurality of limit slots disposed on the limit portions 13 on both sides correspond to each other and are disposed relatively. Fig. 9 As shown, the corresponding and opposite limiting slots 131 on both sides have the same height H1 and the same shape.

[0051] Specifically, Figure 1 and Figure 3 As shown, the limiting slot 131 includes a limiting wall 201 arranged along the lifting direction S and a diaphragm bearing wall 202 connected to the lower end of the limiting wall 201 and extending toward one side of the diaphragm. The limiting wall 201 and the diaphragm bearing wall 202 are arranged perpendicular to each other, and each limiting slot 131 is generally L-shaped. Fig. 9 As shown, the diaphragm bearing walls 202 in the limiting slots 131 on both sides that correspond to each other and are arranged opposite to each other have the same height and the same shape as the limiting walls 201 .

[0052] Further, continue to refer to Figure 1 and Figure 3 A plurality of limit slots are sequentially arranged on the limit portion 13 along the lifting direction S, wherein the limit wall 201 of the upper limit slot 131 in any adjacent limit slots 131 is connected to the limit wall 201 of the lower limit slot 131, and the diaphragm A bearing wall 202 of the upper limit slot 131 extends toward the opposite side of the diaphragm bearing wall 202 of the lower limit slot 131, so that the plurality of limit slots are arranged in a stepped shape along the lifting direction S as a whole.

[0053] Furthermore, if Figure 1 and Figure 3 As shown, the limiting wall 201 includes a guide surface 241, a transition surface 242 and a holding surface 243 which are sequentially arranged along the conveying direction X. The guide surface 241 is inclined along the conveying direction X, and the distance between the guide surfaces on both sides gradually decreases along the conveying direction, so that the diaphragm can be more smoothly guided to enter the stopping body 1 along the conveying direction X. The transition surface 242 is an arc surface so that the diaphragm can better transition from the guide surface 241 to the holding surface 243. The holding surface 243 is a surface that contacts the diaphragm when the diaphragm is at a predetermined position. When the diaphragm is at a predetermined position, the diaphragm abuts against the stopping wall 101 and is held by the holding surface 243.

[0054] When the diaphragm reaches the predetermined position, the clamping surface 243 clamps the diaphragm, and the shape of the clamping surface 243 matches the shape of the clamped portion of the diaphragm.

[0055] In some embodiments, after the diaphragm reaches the predetermined position, the holding surface 243 is held by the diaphragm, and the shape of the holding surface 243 is the same as the shape of the held portion of the diaphragm. For example, when the diaphragm is circular, when the diaphragm is located at the predetermined position, the portion of the diaphragm held by the holding surface 243 is a section of an arc in the circle, and the shape of the holding surface 243 is the same as the shape of the section of the arc held by the holding surface 243; when the diaphragm is square, when the diaphragm is located at the predetermined position, the portion of the diaphragm held by the holding surface 243 is a portion of an edge in the square, and the shape of the holding surface 243 is the same as the shape of the portion of the edge held by the diaphragm. Of course, the holding surface 243 may also be other shapes, as long as it is the same as the shape of the held portion of the diaphragm, and this embodiment is not limited thereto.

[0056] In other embodiments, after the diaphragm reaches the predetermined position, the holding surface 243 is held by the diaphragm, and the shape of the holding surface 243 is different from the shape of the held portion of the diaphragm, as long as the holding surface 243 can hold the diaphragm in the predetermined position, for example, when the diaphragm is circular, the shape of the holding surface 243 can be a straight line, and the holding surface 243 can still hold the diaphragm in the predetermined position.

[0057] In some embodiments, Figure 1 to Figure 2 As shown, the positioning slot 121 includes a stop wall 101 arranged along the lifting direction S and a diaphragm supporting wall 102 connected to the lower end of the stop wall 101 and extending toward one side of the diaphragm, the stop wall 101 and the diaphragm supporting wall 102 are arranged perpendicular to each other, and each positioning slot 121 is generally L-shaped as a whole. A plurality of positioning slots are sequentially arranged along the lifting direction S on the stop portion 12, wherein the diaphragm supporting wall 102 of the upper positioning slot 121 in any adjacent positioning slots is connected to the stop wall 101 of the lower positioning slot 121, and the diaphragm supporting wall 102 of the upper positioning slot 121 extends toward the opposite side of the diaphragm supporting wall 102 of the lower positioning slot 121, so that the plurality of limit slots are arranged in a stepped shape along the lifting direction S as a whole.

[0058] Furthermore, after the diaphragm reaches the predetermined position, the diaphragm is stopped by the stopping wall 101 and abuts against the stopping wall 101 , and the shape of the stopping wall 101 matches the shape of the abutted portion of the diaphragm.

[0059] In some embodiments, after the diaphragm reaches the predetermined position, the diaphragm is stopped by the stopping wall 101 and abuts against the stopping wall 101. The shape of the stopping wall 101 is the same as the shape of the abutted portion of the diaphragm. For example, when the diaphragm is circular, when the diaphragm is at the predetermined position, the portion of the diaphragm abutted by the stopping wall 101 is a section of an arc in the circle, and the shape of the stopping wall 101 is the same as the shape of the section of the arc abutted by the diaphragm; when the diaphragm is square, when the diaphragm is at the predetermined position, the portion of the diaphragm abutted by the stopping wall 101 is a portion of an edge in the square, and the shape of the stopping wall 101 is the same as the shape of the portion of the edge abutted by the diaphragm. Of course, the stopping wall 101 may also be other shapes, as long as they are the same shape as the portion of the diaphragm abutted, and this embodiment is not limited thereto.

[0060] In other embodiments, after the diaphragm reaches the predetermined position, the diaphragm is stopped by the stopping wall 101 and abuts against the stopping wall 101. The shape of the stopping wall 101 is different from the shape of the abutted portion of the diaphragm. As long as the stopping wall 101 can make the diaphragm located at the predetermined position, for example, when the diaphragm is circular, the shape of the stopping wall 101 can be a straight line, and the stopping wall 101 can still stop the diaphragm to the predetermined position.

[0061] In some embodiments, the blocking wall 101 and the diaphragm supporting wall 102 included in any positioning slot 121 are arranged in one-to-one correspondence with the limiting wall 201 and the diaphragm bearing wall 202 included in the corresponding limiting slot 131. Fig. 9 As shown, the height H2 of the diaphragm supporting wall 102 among the one-to-one corresponding blocking walls 101, the diaphragm supporting wall 102, the limiting wall 201 and the diaphragm bearing wall 202 is the same as the height H1 of the diaphragm bearing wall 202. The diaphragm stopped and abutted by the blocking wall 101, the diaphragm guided by the limiting wall 201, the diaphragm supported by the diaphragm supporting wall 102 and the diaphragm carried by the diaphragm bearing wall 202 are the same diaphragm. The shape of the blocking wall 101 is the same as the shape of the portion of the diaphragm abutted after the diaphragm reaches the predetermined position, and the shape of the limiting wall 201 is the same as the shape of the portion of the diaphragm held after the diaphragm reaches the predetermined position. Each corresponding blocking wall 101, the diaphragm supporting wall 102, the limiting wall 201 and the diaphragm bearing wall 202 together enclose a diaphragm accommodating space to accommodate a diaphragm of a certain specification.

[0062] Specifically, Fig. 9As shown, the height H2 of the upper surface of the diaphragm support wall 102 and the height H1 of the upper surface of the diaphragm bearing wall 202 are the same, and the upper surfaces of the corresponding diaphragm support wall 102 and the diaphragm bearing wall 202 respectively bear the lower surface of the same diaphragm. The upper surfaces of the corresponding diaphragm support wall 102 and the diaphragm bearing wall 202 are at the same height, which can make the diaphragm surface parallel to the conveying direction X without tilting, and the diaphragm can smoothly enter the stop body 1 and be convenient to pick up. The upper surfaces of the corresponding diaphragm support wall 102 and the diaphragm bearing wall 202 can also be almost at the same height, and the height difference between the two can meet the production requirements within the preset range.

[0063] In some embodiments, the geometric structure of the stop body 1 satisfies that after diaphragms of different specifications enter a predetermined position, the center points of the diaphragms of different specifications coincide with each other.

[0064] Specifically, Figure 4 and Fig. 9 As shown, the limiting portion 13 is symmetrically arranged on both sides of the stopping portion 12 relative to the stopping portion 12, and the multiple limiting slots on both sides are respectively arranged in one-to-one correspondence with the positioning slots. Among them, the limiting wall includes a guide surface, a transition surface and a holding surface arranged in sequence along the conveying direction. In the limiting slots and positioning slots arranged correspondingly on both sides: the height H1 of the diaphragm bearing walls 202 on both sides is the same as the height H2 of the stopping wall 101, the shapes of the diaphragm bearing walls 202 on both sides are the same, the shape of the stopping wall 101 is the same as the shape of the abutted part of the diaphragm it abuts, and the shape of the holding surface is the same as the shape of the held part of the diaphragm it holds. Multiple positioning slots and multiple limiting slots are arranged in a stepped shape as a whole along the jacking direction. The one-to-one corresponding stop wall 101, diaphragm support wall 102, holding surface 243 and diaphragm bearing wall 202 are enclosed together to form a diaphragm accommodating space. A diaphragm accommodating space accommodates a diaphragm of one specification. The shape of the diaphragm accommodating space is the same as the shape of the diaphragm to be accommodated. For example, if the diaphragm is circular, the shape of the diaphragm accommodating space is circular. The multiple diaphragm accommodating spaces arranged in sequence along the lifting direction S can accommodate diaphragms of different specifications with successively increasing areas, and the distance between adjacent stop walls in the conveying direction X is half of the maximum size difference of the corresponding adjacent diaphragms in the conveying direction X, so that the center points of diaphragms of different specifications coincide. When the lifting mechanism 2 drives the stop body 1 to reciprocate up and down, the multiple diaphragm accommodating spaces arranged in sequence along the lifting direction S can be located at the same position in the lifting direction S. When different diaphragm accommodating spaces are at the same position, the center points of diaphragms of different specifications located at the predetermined position are all located at the same point, so that the precise positioning of the center point of the diaphragm is achieved, which is convenient for subsequent picking.

[0065] Furthermore, if Figure 8As shown, if two adjacent stopping walls are both arc-shaped, the distance between the adjacent stopping walls in the conveying direction X is the distance H1 between the two closest points of the two arc-shaped stopping walls in the conveying direction X; if one of the two adjacent stopping walls is linear and the other is arc-shaped, the distance between the adjacent stopping walls in the conveying direction X is the distance H2 between the point of the arc-shaped stopping wall closest to the linear stopping wall in the conveying direction X and the linear stopping wall; if the two adjacent stopping walls are both linear, the distance between the adjacent stopping walls in the conveying direction X is the distance H3 between the two linear stopping walls. The maximum size of the corresponding adjacent diaphragms in the conveying direction X is the difference between the maximum size of the upper diaphragm in the conveying direction X and the maximum size of the lower diaphragm in the conveying direction X of the adjacent diaphragms accommodated by the adjacent diaphragm accommodating space. The maximum size L of the diaphragm is as shown in FIG. Fig.10 shown.

[0066] In some embodiments, a reserved space N is provided between the stop portion 12 and the limit portion 13 in the conveying direction X to allow the film conveying mechanism to pass through. Figure 7 As shown, the stopper 12 and the limiting parts 13 arranged on both sides are arranged at intervals, and the stopper 12 and the limiting parts 13 on both sides can respectively form a reserved space N, and the reserved space N can be used for the membrane conveying mechanism to pass through.

[0067] In some embodiments, the stopper 12 is disposed at one end of the base 11 along the conveying direction X, and the limiting parts 13 are disposed on both sides of the stopper 12 on the base 11, and the limiting parts 13 are disposed opposite to each other. A first opening is formed at one end of the limiting part 13 in the opposite direction of the conveying direction X, and the diaphragm passes through the first opening to enter the diaphragm accommodating space; a second opening is formed at one end of the limiting part 13 and the stopper 12 along the lifting direction S, and the diaphragm is picked up through the second opening. In some specific cases, such as Figure 1 As shown, the stop body 1 includes a base 11, a stop portion 12 and two limit portions 13. The stop portion 12 is fixedly connected to a top end of the base 11 along the conveying direction X, and the two limit portions 13 are symmetrically arranged on both sides of the base 11 relative to the stop portion 12, and a first opening is formed at one end of the two limit portions 13 away from the stop portion 12, and a second opening is formed at the two limit portions 13 and the stop portion 12 away from the base 11. The diaphragm can pass through the first opening along the conveying direction X into the stop body 1 and be stopped by the stop portion 12 and the two limit portions 13 to a predetermined position, and then the diaphragm can be picked up by the picking device through the second opening along the lifting direction S, which can meet the needs of the diaphragm being stopped and picked up on the production line.

[0070] The conveying assembly 3 includes a conveyor belt 31 for conveying the diaphragm A. The conveyor belt 31 passes through the stop body 1 to convey the diaphragm A to a predetermined position. The conveying width and length of the conveyor belt 31 can be designed according to actual needs, but the conveying width should be slightly larger than the size of the largest diaphragm among the multi-specification diaphragms, so as to adapt to the conveying and transfer of multi-specification diaphragms.

[0071] The diaphragm stop assembly 4 is arranged at one end of the conveyor belt 31 along the conveying direction X. The lifting mechanism can drive the stop body to reciprocate up and down along the lifting direction S so that each positioning slot and its corresponding limit slot are flush with the conveyor belt 31 respectively.

[0072] The picking component 5 can pick up the membrane at a predetermined position along the lifting direction S. When the membranes of different specifications are at the stop position, the center points of the membranes A of different specifications are at the same point, and the same point is the picking starting point of the picking component 5, that is, for the membranes of different specifications, the membrane picking starting point in the picking component 5 is a fixed value, and the picking component 5 can adopt a relatively simple fixed-pitch transfer mechanism (such as PPU, cylinder, etc.) instead of a more expensive robot, thereby improving production efficiency and reducing costs.

[0073] It should be noted that for the detailed description of the diaphragm stop assembly 4 in this embodiment, please refer to the detailed description of the diaphragm stop assembly in Example 1, and this embodiment will not elaborate on the diaphragm stop assembly.

[0074] In some embodiments, Fig.12 As shown, the conveyor belt 31 includes a first conveying portion 311 and a second conveying portion 312, which are symmetrically arranged. The first conveying portion 311 and the second conveying portion 312 pass through the stopping portion 12 and the limiting portions 13 symmetrically arranged on both sides respectively.

[0075] Furthermore, the conveying assembly 3 further includes a blocking portion 32, a guide 33 and a sensor 34, wherein the blocking portion 32 is in two groups and symmetrically arranged on both sides of the conveying belt 31, the blocking body is arranged between the blocking portions 32, the guide 33 is arranged adjacent to the limiting portion 13, the guide 33 is in two groups and symmetrically arranged on both sides of the conveying belt 31 and guides the film on the conveying belt 31 to the blocking body, and the size of the guide 33 from one end away from the limiting portion 13 to the end of the guide 33 close to the limiting portion 13 in a direction perpendicular to the conveying direction X gradually decreases. The sensor 34 is arranged below the conveying belt and adjacent to the blocking body, and the sensor 34 is used to detect the in-place information of the film and feed the in-place information back to the picking assembly 5, and the picking assembly 5 picks up the film according to the feedback information of the sensor 34.

[0076] The working principle of this embodiment is as follows: when the conveyor belt 31 conveys a diaphragm of a certain specification, the lifting mechanism can drive the stop body to move upward or downward along the lifting direction S, so that the bottom surfaces of the positioning slots and the corresponding limit slots adapted to the specifications of the currently conveyed diaphragm are flush with the top surface of the conveyor belt 31. Taking into account that the outer edge of the diaphragm may be bent, the bottom surfaces of the positioning slots and the corresponding limit slots may be slightly lower than the top surface of the conveyor belt 31, so that the diaphragm can enter the stop body more smoothly and steadily. When the diaphragm is stopped at a predetermined position, the sensor 34 feeds back information to the picking component 5, and the picking component 5 picks up the diaphragm with the center point of the diaphragm as the picking starting point according to the feedback information.

[0077] 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.
