Description

Technical Field

[0001] The utility model relates to the technical field of glue-spinning equipment, in particular to a glue-spinning equipment. Background Art

[0002] Glue throwing equipment is a mechanical device that uses the centrifugal force generated by rotation to evenly throw the glue liquid and spread it on the surface of the material. It is commonly used in various experimental or manufacturing fields that have strict requirements on the uniformity of material surface coating, such as semiconductor material research and development and preparation technology, biomaterial physical property analysis, and chemical material film preparation technology.

[0003] In the existing glue-spinning equipment, the glue-spinning cylinder is generally used for active rotation, thereby providing centrifugal force for the glue inside the glue-spinning cylinder, so that the internal glue is ejected under the action of centrifugal force, and finally coated or bonded on the surface of the component, completing the glue-spinning treatment of the component. However, in the glue-spinning process, although the amount of glue in the glue-spinning cylinder is constant, the amount of glue coated or bonded on the surface of each component during the glue-spinning process is difficult to maintain consistency, resulting in excessive glue on the surface of some components, that is, the thickness of the glue-coated surface exceeds the normal value, resulting in excessive glue on the surface of some components and requiring subsequent glue scraping treatment. On the other hand, in the glue-spinning process, part of the glue is not directly coated or bonded on the surface of the component, but bonded to the inner peripheral side wall of the equipment, which not only causes contamination of the surface of the inner peripheral side wall of the equipment, but also causes waste of glue.

[0004] Therefore, it is necessary to invent a glue-spinning device to solve the above problems. Utility Model Content

On the other hand, during the glue throwing process, part of the glue is not directly coated or bonded to the component surface, but bonded to the inner peripheral side wall of the equipment, which not only causes contamination of the surface of the inner peripheral side wall of the equipment, but also causes waste of glue.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A glue-spinning device comprises a vertical cylinder with open ends at the top and bottom and a glue-spinning cylinder rotatably arranged just above the inside of the vertical cylinder and capable of performing glue-spinning, wherein a plurality of positions of the inner circumference of the vertical cylinder equally divide the circumference and are longitudinally slidably abutted against positioning components for placing components to be glued, a plurality of ring bars are longitudinally and synchronously slidably arranged at the top of the vertical cylinder, and the bottom ends of the ring bars are connected to an annular scraper for scraping off adhesive from the inner circumference of the vertical cylinder side wall, the circumferential size of the annular scraper is consistent with the circumferential size of the inner circumference of the vertical cylinder between two adjacent positioning components, and a side clamp is arranged on one side wall where two adjacent ring bars are close to each other, and the spacing between the two side clamps is consistent with the width of the positioning component, a straight bar for controlling the sliding distance is transversely slidably arranged between the two side clamps, and the bottom ends of the straight bars are connected to a straight scraper for scraping off excess glue outside the surface thickness of the component.

The positioning component includes a positioning plate that can slide longitudinally along the inner circumferential side wall of the vertical cylinder and a plurality of adsorption parts for adsorption elements arranged on the side of the positioning plate close to the center of the vertical cylinder. A movable stud that can slide longitudinally along the vertical groove is installed in the middle of the other side of the positioning plate, and a first nut is provided on the threaded sleeve of the part of the movable stud located outside the vertical cylinder.

[0022] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0023] The utility model provides Figure 1-5 The glue-spinning equipment shown in the figure comprises a vertical cylinder 1 with open ends at the top and the bottom, and a glue-spinning cylinder 2 which is rotatably arranged just above the inside of the vertical cylinder 1 and can perform glue-spinning. A plurality of positions of the inner circumference of the vertical cylinder 1 equally divide the circumference and are longitudinally slidably abutted with positioning components for placing the components to be glued. A plurality of ring strips 11 are longitudinally and synchronously slidably arranged at the top of the vertical cylinder 1, and the bottom ends of the ring strips 11 are connected with an annular scraper 12 which can scrape off the adhesive on the inner circumference of the vertical cylinder 1. The circumferential size of the annular scraper 12 is consistent with the circumferential size of the inner circumference of the vertical cylinder 1 between two adjacent positioning components, and a side clamp 13 is arranged on one side wall where two adjacent ring strips 11 are close to each other, and the spacing between the two side clamps 13 is consistent with the width of the positioning component, a straight strip 18 which can control the sliding distance is transversely slidably arranged between the two side clamps 13, and a straight scraper 19 which can scrape off excess glue outside the thickness of the component surface is connected to the bottom end of the straight strip 18. The rotating drive component of the glue-spinning cylinder 2 is not drawn in the figure and belongs to the basic and mature prior art.

[0024] A vertical groove 5 is provided at the position where the vertical cylinder 1 is adapted to each positioning component. The positioning component includes a positioning plate 7 that can slide longitudinally along the inner circumferential side wall of the vertical cylinder 1 and a plurality of adsorption members 8 for adsorbing elements arranged on the positioning plate 7 near the center of the vertical cylinder 1. A movable stud 6 that can slide longitudinally along the vertical groove 5 is installed in the middle of the other side of the positioning plate 7. The part of the movable stud 6 located outside the vertical cylinder 1 is threadedly sleeved with a first nut 20. When it is necessary to adsorb and position the component to be coated with glue on the positioning assembly, the movable stud 6 can be forced to slide to the bottom along the vertical groove 5, so that the positioning plate 7 is exposed from the vertical cylinder 1. When it is necessary to coat the component to be coated with glue, the movable stud 6 is forced to slide to the middle along the vertical groove 5. At this time, the positioning plate 7 is completely placed in the vertical cylinder 1.

[0025] A transverse groove 14 is provided in the side clamping plate 13, and positioning studs 15 that can slide transversely along the transverse groove 14 are installed in the middle of both ends of the straight bar 18. The part of the positioning stud 15 located outside the transverse groove 14 is threadedly sleeved with a second nut 21. By changing the position of the positioning stud 15 in the transverse groove 14, the distance between the straight bar 18 and the positioning plate 7 is changed, that is, the distance between the coating surface of the component to be coated with glue and the straight scraper 19 is changed, so that the excess thickness layer of the component coating surface outside the required thickness is placed under the straight bar 18.

[0026] A scale bar 16 is provided at the top of each side clamp 13, and indicator blocks 17 that can indicate the scale position of the scale bar 16 are provided on both sides of the top of the straight bar 18. The indicator blocks 17 point to the position of the scale bar 16 to control the horizontal sliding distance of the straight bar 18 along the transverse groove 14.

[0027] A stand 9 is installed at the position where each ring strip 11 is adapted to the top side of the outer peripheral side wall of the vertical tube 1, and a holder 22 is installed on the top side of the inner peripheral side wall of each ring strip 11. A telescopic member 10 that can be longitudinally extended and retracted is installed in the stand 9. The bottom end of the telescopic member 10 is detachably connected to the top end of the holder 22. The telescopic member 10 is longitudinally extended and retracted, thereby driving multiple straight strips 18 and the ring strips 11 to move synchronously along the longitudinal downward direction of the vertical tube 1, thereby completing the scraping process of the glue at different positions.

[0028] A cylinder cover 3 is rotatably mounted on the top of the rubber spinning cylinder 2, and a glue inlet pipe 4 for feeding glue into the rubber spinning cylinder 2 is installed on the top of the cylinder cover 3. During the rotation of the rubber spinning cylinder 2, the cylinder cover 3 is always guaranteed not to rotate, so that the glue inlet pipe 4 can feed glue into the rubber spinning cylinder 2 at a fixed position.

[0029] In the utility model, the positioning assembly positions and fixes the component to be coated with glue at multiple positions of the vertical cylinder 1, and drives the glue-spinning cylinder 2 to rotate, so that the glue is evenly sprinkled from the glue-spinning cylinder 2 under the action of centrifugal force and coated or bonded to the surface of the component. After a single glue-spinning is completed, according to the actual amount of glue thickness that needs to be coated or bonded on the surface of the component, the horizontal position of the straight strip 18 on the two side clamping plates 13 is changed to adjust the distance between the straight strip 18 and the component coating layer, so that the excess thickness layer of the component coating surface outside the required thickness is placed under the straight strip 18, and then the multiple ring strips 11 are driven to rotate. Move downward into the vertical tube 1, and use the straight scraper 19 under the multiple straight bars 18 to scrape down the excess glue on the component surface of each positioning component beyond the required thickness. In the synchronous process, the annular scraper 12 under the multiple ring bars 11 scrapes down the glue adhered to the inner side wall of the vertical tube 1. On the one hand, it can avoid excessive coating on the component surface causing the glue layer to be too thick. On the other hand, it can simultaneously scrape off the glue adhered to the inner side wall of the vertical tube 1 to avoid the inner side wall of the vertical tube 1 being contaminated by glue. The scraped glue is discharged through the bottom opening of the vertical tube 1, so that the excess glue can be recovered to avoid excessive waste of glue.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
