[0028] In the embodiment of the present application, the shell 10 carries the glue, and the carrier 30 is driven to rotate by the first driving mechanism 40, so that the glue column 20 can rotate and contact the glue in the shell 10. The glue column 20 adheres to the glue, the carrier 30 and the glue column 20 are driven to rotate by the first driving mechanism 40, so that the glue column 20 adhering to the glue rotates to the opening 12 of the hollow cavity 11, so that the glue column 20 adhering to the glue at the opening 12 can be used to cooperate with the product needing to be isolated by glue, and the glue adhering to the glue column 20 can be transferred to the product needing to be isolated by glue, so as to realize glue dispensing for the product.

[0029] In the embodiment of the present application, the first driving mechanism 40 includes a driving member 41 and a rotating shaft 42, the rotating shaft 42 is rotatably arranged on at least one side wall 13 of the shell 10, and the carrier 30 is fixedly arranged on the rotating shaft 42. In the embodiment of the present application, the driving member 41 can be a motor, which drives the rotating shaft 42 to rotate, so that the glue column 20 on the carrier 30 is switched between facing the opening 12 of the hollow cavity 11 and facing away from the opening 12 of the hollow cavity 11.

[0030] In the embodiment of the present application, the rotating shaft 42 is rotatably arranged on the two opposite side walls 13 of the shell 10, and the carrier 30 is rotatably arranged on the rotating shaft 42 and located between the two side walls 13. In the embodiment of the present application, the shell 10 is a square or rectangular structure having an opening 12 at one end. By rotatably arranging the rotating shaft 42 on the two opposite side walls 13 of the shell 10 and rotatably fixing the rotating shaft 42 on the two side walls 13, the stability of the rotating shaft 42 is strong, so that the stability of the carrier 30 located on the rotating shaft 42 is strong. In other embodiments, the rotating shaft 42 can be rotatably arranged on one side wall 13 of the shell 10, so that the rotating shaft 42 can be rotatably fixed on the side wall 13. In another embodiment, the shell 10 can be a cylindrical structure having an opening 12 at one end, and the rotating shaft 42 can be rotatably arranged on the side wall 13 of the shell 10 and rotatably fixed on the side wall 13 of the shell 10 at both ends. In the embodiment of the present application, the rotating shaft 42 is located at the center position of the side wall 13 of the shell 10 in the width direction, so that the carrier 30 is located at the middle position of the hollow cavity 11. In other embodiments, the rotating shaft 42 can also be rotatably arranged at a non-central position of the side wall 13 of the shell 10 in the width direction. In still another embodiment, the rotating shaft 42 can be supported on the side wall 13 of the shell 10 by a support (not shown).

[0031] In this embodiment, the dispensing device further includes a support base 43. One end of the support base 43 is fixed to the housing 10, and the other end of the support base 43 supports and fixes the driving member 41. By setting the support base 43, the driving member 41 is fixed relative to the housing 10, and the dispensing device is made into a single unit, facilitating its movement. In this embodiment, one end of the support base 43 is fixed to the bottom plate 14 of the housing 10. Specifically, in this embodiment, the bottom plate 14 of the housing 10 extends along the planar direction, extending beyond the side wall 13 to form an extension portion 141. In this embodiment, the support base 43 is disposed on the extension portion 141 of the bottom plate 14. In other embodiments, the support base 43 may also be fixed to the side wall 13 of the housing 10.

[0032] As the amount of adhesive in the hollow cavity 11 of the housing 10 decreases during use, the dispensing column 20 may not be able to adhere enough adhesive, or may not be able to adhere to the adhesive at all, thus affecting the dispensing performance of the dispensing column 20. Therefore, as... Figure 4 As shown, in another embodiment of this application, the first driving mechanism 40 includes a rotating member 45, a first driving component 44, a lifting mechanism 46, a support member 47, and a second driving component (not shown). The carrier 30 is disposed on the rotating member 45, and the rotation of the rotating member 45 drives the carrier 30 to rotate. The first driving component 44 is used to drive the rotating member 45 to rotate. The first driving component 44 is disposed on the lifting mechanism 46, so that the lifting mechanism 46 rises and falls to drive the rotating member 45 and the carrier 30 to rise and fall relative to the bottom plate 14 of the housing 10. The support member 47 is used to support and fix the lifting mechanism 46. The second driving component is used to drive the lifting mechanism 46 to rise and fall. The second driving component is disposed on the support member 47 and connected to the lifting mechanism 46, and is used to drive the lifting mechanism 46 to rise or fall.

[0033] In this embodiment, the rotating member 45 can be a rotating rod, the first driving member 44 and the second driving member can be a motor, the support member 47 is a support rod, and the lifting mechanism 46 is a sliding assembly. Alternatively, the lifting mechanism 46 can also be a lead screw assembly.

[0034] Specifically, in this embodiment, the support member 47 is fixed to the side wall 13 of the housing 10. In other embodiments, the support member 47 can also be separately disposed outside the housing 10, so that the distance between the support member 47 and the bottom plate 14 of the housing 10 is fixed. The lifting assembly in this embodiment includes a slide rail 461, a slider 462, and a connector 463. The connector 463 is fixed to the slider 462. The second driving component is used to directly or indirectly drive the slider 462 to move along the slide rail 461. The slide rail 461 is arranged perpendicular to the bottom plate 14 of the housing 10.

[0035] When the amount of the glue in the hollow cavity 11 is reduced, the second driving component can be used to drive the lifting mechanism 46, so that the first driving component 44, the rotating component 45, the carrier 30 and the glue dispensing column 20 are lowered, so that the glue dispensing column 20 can touch and adhere to the glue, and the first driving component 41 drives the rotating component 45 to rotate, so that the carrier 30 rotates, and the glue dispensing column 20 adheres to the glue and turns to the opening 12 of the hollow cavity 11.

[0036] In the embodiment of the present application, the glue carried by the hollow cavity 11 is a mixture of sand and high-temperature-resistant glue.

[0037] In the embodiment of the present application, as shown in Figure 1 and Figure 2 The glue dispensing device further comprises a stirring device 50, and the stirring device 50 is used to stir the glue carried by the hollow cavity 11. In the embodiment of the present application, the stirring device 50 can be used to uniformly mix the sand and the high-temperature-resistant glue, so that the glue adhered by the glue dispensing column 20 is glue with good uniformity, and the sand is prevented from forming a precipitate in the static high-temperature-resistant glue.

[0038] In the embodiment of the present application, the shell 10 comprises a fixed plate 15 located at the end face of the opening 12, the stirring device 50 comprises a second driving mechanism 51 and a stirrer 52, the second driving mechanism 51 is fixed to the fixed plate 15, and the stirrer 52 is arranged at the driving end of the second driving mechanism 51. In the embodiment of the present application, the shell 10 can be used to support and fix the second driving mechanism 51 and the stirrer 52 by arranging the fixed plate 15, so that the relative positions of the second driving mechanism 51 and the stirrer 52 to the hollow cavity 11 in the shell 10 are fixed, and other devices are not needed to assist in fixing the second driving mechanism 51 and the stirrer 52. In the embodiment of the present application, the position of the stirring device 50 is fixed relative to the distance of the carrier 30 by arranging the fixed plate 15, so that the stirring of the stirrer 52 can be reasonably controlled, and the influence of the stirring of the stirrer 52 on the glue adhered by the glue dispensing column 20 is reduced.

[0039] In the embodiment of the present application, the fixed plate 15 is fixed to the adjacent two side walls 13, so that the stirrer 52 does not contact the first driving mechanism 40, the glue dispensing column 20 and the carrier 30. In the embodiment of the present application, the fixed plate 15 is fixed to the intersection position of the adjacent two side walls 13, so that the stirrer 52 is located at the corner of the hollow cavity 11 to stir, and the sand and the high-temperature-resistant glue are uniformly mixed while the glue adhered by the glue dispensing column 20 is not affected. For example, the glue adhered by the same glue dispensing column 20 is uniform, and the glue adhered by different glue dispensing columns 20 is uniform relative to each other.

[0040] In the embodiment of the present application, as shown in Figure 5As shown, the end face of the dispensing column 20 away from the carrier 30 is concave. By setting the end of the dispensing column 20 away from the carrier 30 as concave, the dispensing column 20 is easier to adhere to the glue, especially for the glue with high viscosity, by using the surface force between the dispensing column 20 and the glue. Figure 3 As shown, in another embodiment, the end face of the dispensing column 20 away from the carrier 30 can also be flat. The flat end can be used to adhere to the glue.

[0041] In the embodiment of the present application, as shown in Figure 1 and 3 The carrier 30 has a bearing surface 31 around the rotation shaft 42, and the dispensing column 20 is a plurality of dispensing columns. The ends of the plurality of dispensing columns 20 on the same bearing surface 31 away from the bearing surface 31 are coplanar. The plurality of dispensing columns 20 on the same bearing surface 31 are arranged to have their ends away from the bearing surface 31 coplanar, so that the plurality of dispensing columns 20 can dispense a plurality of glue points on the same face of the product that needs to be isolated by glue, and can ensure that the plurality of glue points on the same face of the product that needs to be isolated by glue are uniform. In the embodiment of the present application, the dispensing columns 20 on the same face are three or more, specifically, the dispensing columns 20 on the same face are four in the embodiment of the present application, and the positions of the four dispensing columns 20 form a quadrilateral, and the four glue points determine a plane, so that the adjacent two products are separated by the four glue points, avoiding direct contact between the products. In another embodiment, the dispensing columns 20 can also be three or more than four, and the three or more than four dispensing columns 20 are not on a straight line, so that the ends of the plurality of dispensing columns 20 away from the bearing surface 31 are located on the same plane, and a plane can be determined, so that one face of the ceramic body and the like is dispensed with a plurality of glue points by the dispensing device.

[0042] As shown in Figure 1 and Figure 3 When the end of the dispensing column 20 away from the bearing surface 31 is flat, the ends of the plurality of dispensing columns 20 on the same bearing surface 31 away from the bearing surface 31 are on the same plane. As shown in Figure 5 When the end of the dispensing column 20 away from the bearing surface 31 is concave, the shapes of the concave surfaces of the plurality of dispensing columns 20 are the same, the highest surfaces of the concave surfaces of the ends of the plurality of dispensing columns 20 away from the bearing surface 31 are on the same plane, and the lowest surfaces of the concave surfaces of the ends of the plurality of dispensing columns 20 away from the bearing surface 31 are also on the same plane.

[0043] In the embodiment of the present application, as shown in Figure 1 and Figure 3As shown, the carrier 30 includes four bearing surfaces 31, and the glue dispensing columns 20 are arranged on at least two bearing surfaces 31. In the embodiment of the present application, the glue dispensing columns 20 are arranged on two opposite bearing surfaces 31, so that when the glue dispensing columns 20 on one bearing surface 31 are turned to the opening 12 of the hollow cavity 11, the glue dispensing columns 20 on the other bearing surface 31 can adhere glue. Thus, the glue dispensing columns 20 on one bearing surface 31 perform glue dispensing, and the glue dispensing columns 20 on the other bearing surface 31 perform glue adhering, so that the glue dispensing columns 20 on the two opposite bearing surfaces 31 alternately perform glue adhering and glue dispensing, and the efficiency of glue dispensing of the glue dispensing columns 20 can be improved. In other embodiments, the glue dispensing columns 20 can be arranged on only one bearing surface 31, or can be arranged on two adjacent bearing surfaces 31, which can improve the glue dispensing efficiency to a certain extent, or can be arranged on all four bearing surfaces 31, which can greatly improve the glue dispensing efficiency.

[0044] In another embodiment, the carrier 30 is a cylinder, and the side surface of the carrier 30 is circular. The glue dispensing columns 20 can be arranged on opposite sides of the side surface of the carrier 30, and the glue dispensing efficiency can also be improved. At this time, the circular side surface is provided with a plurality of glue dispensing columns 20, the heights of the plurality of glue dispensing columns 20 are not completely the same, but the glue dispensing columns 20 are coplanar at the end far from the carrier 30.

[0045] The above is only the implementation of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
