[0006] In some embodiments, the positioning structure is made of an elastic material corresponding to one end of the groove opening.
[0007] In some embodiments, the positioning structure includes: a positioning ring and a plurality of positioning columns; the positioning ring is arranged around the inner side wall of the groove; one end of the positioning column is connected with the inner bottom wall of the groove, and the other end extends to the opening direction of the groove, and the distance between the positioning column and the opening of the groove is consistent with the distance between the positioning ring and the opening of the groove; wherein the first interval distance is provided between the positioning column and the positioning ring; and / or, the second interval distance is provided between at least one group of two positioning columns adjacent to each other.
[0008] In some embodiments, the shapes of any two positioning columns are consistent or inconsistent; and / or, the plurality of positioning columns are distributed at equal intervals, and the distance between any two adjacent positioning columns is equal to the distance between the positioning ring and the positioning column close to the positioning ring.
[0009] In some embodiments, the cross-sectional dimension of the positioning column corresponding to one end of the inner bottom wall of the groove is greater than the cross-sectional dimension corresponding to one end of the groove opening.
[0010] In some embodiments, when the other end opening of the channel is arranged at the inner side wall of the recess, the recess has a first inner side wall and a second inner side wall opposite to each other, the other end opening of the channel is arranged at the first inner side wall, and the projection of the other end opening of the channel on the second inner side wall is misaligned with the projection of the plurality of positioning columns on the second inner side wall; when the other end opening of the channel is arranged at the positioning structure, the other end opening of the channel is arranged at the side of the positioning column corresponding to the opening of the recess and / or the surface of the inner side wall of the recess corresponding to the positioning column.
[0011] In some embodiments, the positioning structure comprises a plurality of positioning rods, the plurality of positioning rods are arranged in a circle and spaced apart from each other around the inner side wall of the recess, one end of each positioning rod is connected to the inner side wall of the recess, the other end extends in a direction perpendicular to the depth direction of the recess, and the length of any positioning rod is less than the distance between the two inner side walls of the recess corresponding to the length direction of the corresponding positioning rod.
[0012] In some embodiments, the extension directions of any two positioning rods are consistent or inconsistent.
[0013] In some embodiments, the cross-sectional dimension of the side of the positioning rod away from the inner bottom wall of the recess is smaller than the cross-sectional dimension of the side of the positioning rod close to the inner bottom wall of the recess.
[0014] In a second aspect, the disclosure also provides a silk-screen printing device, which can comprise a silk-screen printing platform and the positioning device of any one of the embodiments of the first aspect, the body of the positioning device is detachably connected to the silk-screen printing platform, and the first surface of the body is exposed from the silk-screen printing platform when the body is connected to the silk-screen printing platform.
[0015] Through the above technical solutions, the positioning device and the silk-screen printing device provided by the disclosure can comprise a body and a positioning structure, the body has a recess, and the positioning structure is arranged in the recess to form a positioning space between the positioning structure in the recess and the opening of the recess. In addition, the positioning device is also provided with a channel, the two end openings of the channel are located outside the body and in the recess, respectively. In this way, after the to-be-silk-screen-printed piece is placed in the positioning space, it can be preliminarily positioned by the body and the positioning structure, and then it can be more firmly adsorbed in the positioning space by drawing air into the channel. The double arrangement of preliminary positioning and adsorption makes the probability of displacement of the positioned to-be-silk-screen-printed piece small, thereby reducing the probability of silk-screen printing failure. Since the projection of the positioning structure on the inner bottom wall of the recess does not completely cover the inner bottom wall of the recess, the part of the surface of the to-be-silk-screen-printed piece corresponding to the side of the inner bottom wall of the recess does not contact the positioning structure, that is, the contact area between the to-be-silk-screen-printed piece and the positioning device is small, thereby reducing the probability of scratching the to-be-silk-screen-printed piece by the positioning device due to friction between the to-be-silk-screen-printed piece and the positioning device.

[0029] Techniques, methods and equipment known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be considered as part of the specification.
[0030] In the silk screen printing process, the to-be-silk-screened part needs to be positioned in a pre-set positioning area, and then the surface of the positioned to-be-silk-screened part is subjected to silk screen printing treatment.
[0031] In the related art, after the to-be-silk-screened part is positioned in the positioning area, friction between the to-be-silk-screened part and the positioning area is prone to occur, and adverse phenomena such as scratches are prone to occur.
[0032] In view of this, the present disclosure provides a positioning device, which forms a positioning space in a groove by a main body and a positioning structure arranged in the groove, the positioning space being used to accommodate a to-be-screen-printed piece, the positioning structure supporting the to-be-screen-printed piece, and since the orthogonal projection of the positioning structure to the inner bottom wall of the groove does not completely cover the inner bottom wall of the groove, the part of the surface of the to-be-screen-printed piece corresponding to the side of the inner bottom wall of the groove does not contact the positioning structure, that is, the area of the positioning region is reduced, so that the contact area between the to-be-screen-printed piece and the positioning device can be reduced, and thus the probability that the to-be-screen-printed piece is scratched by the positioning device due to friction between the to-be-screen-printed piece and the positioning device can be reduced.
[0033] First aspect
[0034] Referring to Figures 1 to 3 As shown, the positioning device can include a main body 1 and a positioning structure 2, the main body 1 has a first surface 11 and a second surface (not shown in the figure), the first surface 11 is recessed with a groove 12; the positioning structure 2 is arranged in the groove 12 and the orthogonal projection of the inner bottom wall 13 of the groove 12 to the inner bottom wall 13 of the groove 12 does not completely cover the inner bottom wall 13 of the groove 12, and the side of the positioning structure 2 away from the inner bottom wall 13 of the groove 12 and the opening of the groove 12 form a positioning space 14; wherein the positioning device is further provided with a channel (not shown in the figure), one end of the channel is opened corresponding to the second surface of the main body 1, the other end of the channel is opened on the inner wall outside the positioning space 14 formed in the groove 12 and / or on the positioning structure 2, and the other end of the channel is communicated with the positioning space 14.
[0035] The main body 1 has a first surface 11 and a second surface, the first surface 11 and the second surface can be two surfaces on the main body 1 opposite to each other, can be two surfaces adjacent to each other, or can be two surfaces neither opposite nor adjacent to each other, hereinafter for the convenience of description, the first surface 11 and the second surface are taken as an example of two surfaces opposite to each other. The first surface 11 of the main body 1 is recessed with a groove 12, in the case that the first surface 11 and the second surface are opposite to each other, the recess direction of the groove 12 can be consistent with the direction from the first surface 11 to the second surface.
[0036] The positioning structure 2 is arranged in the groove 12 of the main body 1 and has a distance from the opening of the groove 12, so that a positioning space 14 can be formed between the opening of the groove 12 and the positioning structure 2 in the groove 12, and the size of the positioning space 14 is consistent with the size of the to-be-screen-printed object, so that the to-be-screen-printed object can be preliminarily positioned relative to the positioning device after being located in the positioning space 14. The orthographic projection of the positioning structure 2 to the inner bottom wall 13 of the groove 12 does not completely cover the inner bottom wall 13 of the groove 12, so that the positioning structure 2 has a through hole extending along the depth direction of the groove 12, or the positioning structure 2 includes multiple parts and has a space inside one part and / or between multiple parts (for example, there is a space between the positioning ring 21 and the positioning column 22, and there is a space between the positioning column 22 and the positioning column 22), so that the to-be-screen-printed object in the positioning space 14 contacts the positioning structure 2 on the partial surface of the side surface corresponding to the inner bottom wall 13 of the groove 12, and the partial surface is not contacted, so that the contact area between the to-be-screen-printed object after positioning and the positioning device (which can also be referred to as a positioning area) can be reduced, and then the friction area between the to-be-screen-printed object and the positioning device can be reduced, so that the to-be-screen-printed object can be prevented from being scratched and other adverse phenomena.
[0037] The positioning device is further provided with a channel, and the two openings of the channel are located outside the main body 1 and inside the groove 12, respectively, so that in the case that the opening of the channel located outside the main body 1 is connected to the vacuum device and vacuumized, the to-be-screen-printed object can be adsorbed in the positioning space 14, so that the to-be-screen-printed object in the positioning space 14 can be more firmly positioned. The opening of the channel located inside the groove 12 can be arranged on the inner side wall of the groove 12 and does not include the inner side wall forming the positioning space 14, or can be arranged on the positioning structure 2, or both positions are arranged, and the opening of the channel located inside the groove 12 is in communication with the positioning space 14.
[0038] In an example, a screen printing device can include a screen printing platform and a positioning device, the main body 1 of the positioning device is detachably connected to the screen printing platform, and in the case that the main body 1 is connected to the screen printing platform, the first surface 11 of the main body 1 is exposed from the upper surface of the screen printing platform. The positioning device can include a main body 1 and a positioning structure 2, the main body 1 has a first surface 11 and a second surface opposite to each other, and the first surface 11 is recessed with a groove 12; the positioning structure 2 is arranged in the groove 12 and the orthographic projection of the positioning structure 2 to the inner bottom wall 13 of the groove 12 does not completely cover the inner bottom wall 13 of the groove 12, and the side of the positioning structure 2 away from the inner bottom wall 13 of the groove 12 forms a positioning space 14 with the opening of the groove 12; wherein the positioning device is further provided with a channel, one end opening of the channel corresponds to the second surface of the main body 1, and the other end opening of the channel is arranged on the inner wall of the groove 12 outside the positioning space 14 and on the positioning structure 2, and the other end opening of the channel is in communication with the positioning space 14. A method for using the screen printing device is as follows:
[0039] S101: placing the to-be-screen-printed piece in the positioning space 14;
[0040] S102: performing a vacuumizing operation by the vacuumizing device connected through the passage opening of the second surface, so that the to-be-screen-printed piece is adsorbed in the positioning space 14;
[0041] S103: performing a screen printing process on the surface of the to-be-screen-printed piece opposite to the inner bottom wall 13 of the groove 12 by the screen printing device of the screen printing equipment.
[0042] In the embodiment, the positioning device can include a main body 1 and a positioning structure 2, the main body 1 is recessed with a groove 12, the positioning structure 2 is arranged in the groove 12 to form a positioning space 14 between the positioning structure 2 in the groove 12 and the opening of the groove 12, and the positioning device is further provided with a passage, the two ends of the passage are respectively opened outside the main body 1 and in the groove 12, so that the to-be-screen-printed piece can be placed in the positioning space 14 and preliminarily positioned by the main body 1 and the positioning structure 2, and then the to-be-screen-printed piece is more firmly adsorbed in the positioning space 14 by drawing air into the passage, the double setting of preliminary positioning and adsorption makes the probability of displacement of the positioned to-be-screen-printed piece small, and thus the probability of screen printing failure can be reduced; since the orthogonal projection of the positioning structure 2 to the inner bottom wall 13 of the groove 12 does not completely cover the inner bottom wall 13 of the groove 12, so that the part of the surface of the to-be-screen-printed piece corresponding to one side of the inner bottom wall 13 of the groove 12 does not contact the positioning structure 2, that is, the contact area between the to-be-screen-printed piece and the positioning device is small, so that the probability of the to-be-screen-printed piece being scratched by the positioning device due to friction between them can be reduced; at the same time, since the orthogonal projection of the positioning structure 2 to the inner bottom wall 13 of the groove 12 does not completely cover the inner bottom wall 13 of the groove 12, the space in the positioning structure 2 can be adsorbed, so that the air pressure during adsorption can be increased, the positioning accuracy of the to-be-screen-printed piece is further ensured, and the screen printing yield is improved.
[0043] In some embodiments, the end of the positioning structure 2 corresponding to the opening of the groove 12 is made of elastic material. In this way, the end of the positioning structure 2 corresponding to the opening of the groove 12 can form a buffer during the vacuumizing process to reduce the probability of scratches caused by multiple frictions between the to-be-screen-printed piece and the positioning structure 2 due to severe shaking of the to-be-screen-printed piece, and in the case that the thickness of the positioning structure 2 at different positions in the thickness direction of the groove 12 has a tolerance, the elastic part can have different compression amounts to eliminate the probability of the to-be-screen-printed piece being unstable due to the tolerance.
[0044] In some embodiments, referring to Figure 1 and Figure 2As shown, the positioning structure 2 can include a positioning ring 21 and a plurality of positioning columns 22; the positioning ring 21 is arranged around the inner side wall of the groove 12; one end of the positioning column 22 is connected with the inner bottom wall 13 of the groove 12, and the other end extends to the opening direction of the groove 12, and the distance between the positioning column 22 and the opening of the groove 12 is consistent with the distance between the positioning ring 21 and the opening of the groove 12; wherein the first interval distance is between the positioning column 22 and the positioning ring 21; and / or, the second interval distance is between at least one group of two positioning columns 22 adjacent to each other.
[0045] The distance between the positioning column 22 and the opening of the groove 12 is consistent with the distance between the positioning ring 21 and the opening of the groove 12, so that the thickness of different positions of the positioning space 14 in the depth direction of the groove 12 is consistent, thereby the positioning of the to-be-screened member with consistent thickness at different positions during the screen printing process can be realized. The first interval distance is arranged, so that the opening of the channel located in the groove 12 can be adsorbed by the space formed by the first interval distance; the second interval distance is arranged, so that the opening of the channel located in the groove 12 can be adsorbed by the space formed by the second interval distance.
[0046] Here, the positioning ring 21 and the plurality of positioning columns 22 can be integrally formed on the main body 1, or can be fixed on the main body 1 by bonding or the like.
[0047] In some embodiments, referring to Figure 1 and Figure 2 As shown, the shapes of any two positioning columns 22 are consistent or inconsistent; and / or, the plurality of positioning columns 22 are distributed at equal intervals, and the distance between any two adjacent positioning columns 22 is equal to the distance between the positioning ring 21 and the positioning column 22 close to the positioning ring 21.
[0048] In the case that the shapes of any two positioning columns 22 are consistent, the manufacturing equipment of the plurality of positioning columns 22 can be simplified, and the plurality of positioning columns 22 can have consistent beauty; in the case that the shapes of any two positioning columns 22 are inconsistent, the positioning columns 22 with different shapes can be arranged according to the different thicknesses of different positions of the to-be-screened member, the different materials of different positions, etc., so that the supporting degrees of different positioning columns 22 to different positions of the to-be-screened member tend to be consistent, thereby more stable support to the to-be-screened member can be realized.
[0049] The plurality of positioning columns 22 are distributed at equal intervals, so that the positioning structure 2 can have a plurality of sub-adsorption spaces (a plurality of adjacent positioning columns 22 form a sub-adsorption space), and the plurality of sub-adsorption spaces are of the same size, so that the to-be-printed object can be more stably adsorbed. The distance between any two adjacent positioning columns 22 is equal to the distance between the positioning ring 21 and the positioning column 22 close to the positioning ring 21, so that a sub-adsorption space can also be formed between the positioning column 22 and the positioning ring 21. In this way, the number of sub-adsorption spaces can be increased, so as to further realize more stable support of the to-be-printed object.
[0050] In some embodiments, the cross-sectional dimension of the positioning column 22 corresponding to one end of the inner bottom wall 13 of the groove 12 is greater than the cross-sectional dimension corresponding to the opening end of the groove 12. In this way, the contact area between the to-be-printed object and the positioning device can be further reduced, thereby reducing the probability of relative friction and scratches.
[0051] In some embodiments, when the other-end opening of the channel is arranged on the inner side wall of the groove 12, the groove 12 has a first inner side wall and a second inner side wall opposite to each other, the other-end opening of the channel is arranged on the first inner side wall, and the orthographic projection of the other-end opening of the channel to the second inner side wall is misaligned with the orthographic projection of the plurality of positioning columns 22 to the second inner side wall; when the other-end opening of the channel is arranged on the positioning structure 2, the other-end opening of the channel is arranged on the side of the positioning column 22 corresponding to the opening of the groove 12 and / or the surface of the inner side wall of the groove 12 corresponding to the positioning column 22.
[0052] When the other-end opening of the channel is arranged on the inner side wall of the groove 12, the groove 12 has a first inner side wall and a second inner side wall opposite to each other, the other-end opening of the channel is arranged on the first inner side wall, and the orthographic projection of the other-end opening of the channel to the second inner side wall is misaligned with the orthographic projection of the plurality of positioning columns 22 to the second inner side wall, that is, the opening of the channel corresponding to the groove 12 is located on the inner side wall of the groove 12, and the opening is misaligned with the positioning column 22, so as to reduce the loss of adsorption force of the positioning column 22, thereby ensuring the adsorption force of the to-be-printed object.
[0053] When the other-end opening of the channel is arranged on the side of the positioning column 22 corresponding to the opening of the groove 12, the opening is directly opposite to the to-be-printed object, so as to reduce the loss of adsorption force; when the other-end opening of the channel is arranged on the surface of the inner side wall of the groove 12 corresponding to the positioning column 22, and the first surface 11 is upward, the probability of particles entering the channel from the opening can be reduced.
[0054] In other embodiments, referring to Figure 3As shown, the positioning structure 2 comprises a plurality of positioning rods 23 arranged in a circle and spaced apart from each other around the inner side wall of the groove 12, one end of each positioning rod 23 is connected with the inner side wall of the groove 12, the other end extends in a direction perpendicular to the depth direction of the groove 12, and the length of each positioning rod 23 is less than the distance between the two inner side walls of the groove 12 corresponding to the length direction of the positioning rod 23. In this way, the to-be-screened object can be placed in the positioning space 14 defined between the plurality of positioning rods 23 and the opening of the groove 12, and the central position of the groove 12 is left empty, so that sufficient adsorption gas pressure can be provided during the adsorption of the to-be-screened object, thereby making the to-be-screened object more stable and the screen printing yield higher.
[0055] In some embodiments, the extension directions of any two positioning rods 23 are consistent or inconsistent. That is, the lengths of different positioning rods 23 can be consistent or inconsistent; in the case where the lengths of all the positioning rods 23 are consistent, the positioning device can have a visually pleasing appearance, and in the case where the lengths of different positioning rods 23 are different, the limitation on the raw materials for manufacturing the positioning rods 23 can be reduced.
[0056] In some embodiments, referring to Figure 3 As shown, the cross-sectional dimension of the positioning rod 23 on the side away from the inner bottom wall 13 of the groove 12 is smaller than the cross-sectional dimension of the positioning rod 23 on the side close to the inner bottom wall 13 of the groove 12. In this way, the contact area between the positioning rod 23 and the to-be-screened object is small, so that the probability of friction between the to-be-screened object and the positioning device to cause scratches is small.

[0059] The first surface 11 of the main body 1 is exposed from the screen printing platform, so that the to-be-screened object can be directly placed in the positioning space 14, for example, the screen printing platform is located at the upper end of the screen printing device, and the first surface 11 is flush with the upper surface of the screen printing platform. The first surface 11 of the main body 1 can also not be exposed from the screen printing platform, for example, in the case where the main body 1 is connected with the screen printing platform, the first surface 11 of the main body 1 is covered by a cover body provided on the screen printing device to protect the positioning device, and when screen printing is performed, the cover body can be removed to expose the main body 1.
