Description

Technical Field

[0001] This utility model relates to the field of epoxy molding compound technology, specifically to an epoxy molding compound powder dispersion and extrusion device. Background Technology

[0002] Epoxy molding compounds are thermosetting plastics, meaning that the resin can be cured by increasing temperature and pressure. Fully cured products cannot be reheated and cannot be remelted. This product can be used for chip packaging and integrated circuit packaging. Epoxy molding compounds are powdered molding compounds made of epoxy resin and various additives.

[0003] According to the published information on an automatic dispersion and extrusion device and method for epoxy molding compound powder (Announcement No.: CN115972439B), the aforementioned application utilizes a servo motor to drive a reciprocating screw to rotate stably, thereby driving a threaded connecting plate to perform stable up-and-down reciprocating motion within a fixed frame. The cooperation of the feeding trough and the conveying trough allows for the automatic and stable intermittent delivery of epoxy molding compound powder from the storage bin to the device housing. This ensures the stability of subsequent dispersion processing of the epoxy molding compound powder, avoids blockages inside the device caused by a large amount of epoxy molding compound powder being added at once, and increases the ease of use and stability of the device.

[0004] However, in actual use, the plastic powder in the above-mentioned equipment can only move downward through the conveyor cylinder, making it difficult to diffuse the range of plastic powder feeding. This makes it difficult for the plastic powder to be fully dispersed, and the powder is still easy to agglomerate and form clumps. In view of this, we propose an epoxy molding compound powder dispersion extrusion device. Utility Model Content

[0005] The purpose of this invention is to provide an epoxy molding compound powder dispersion and extrusion device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an epoxy molding compound powder dispersion and extrusion device, comprising a sleeve, an inlet fixedly connected to the upper outer wall of the sleeve, a connecting plate fixedly connected to the outer wall of the sleeve, a feeding motor fixedly connected to the end of the connecting plate away from the sleeve, a drive shaft fixedly connected to the output end of the feeding motor, a spiral auger fixedly connected to the outer wall of the drive shaft, and a dispersion component disposed inside the sleeve, the dispersion component comprising:

[0007] A housing is fixedly connected to the outer wall of a sleeve. A rotating motor is fixedly connected to the inner wall of the housing. A gear is fixedly connected to the output end of the rotating motor. A gear ring meshes with the outer wall of the gear.

[0008] A limiting plate is fixedly connected to the outer wall of the toothed ring. A storage sleeve is fixedly connected to the lower outer wall of the limiting plate. A filter screen is fixedly connected to the lower outer wall of the storage sleeve. A movable groove is opened on the inner wall of the sleeve.

[0009] Preferably, the casing is provided with a material-dispensing assembly, which includes a fixed plate fixedly connected to the lower outer wall of the drive shaft. A movable plate is slidably connected to the inner wall of the fixed plate, and a sliding rod is fixedly connected to the inner wall of the fixed plate. A spring is sleeved on the outer wall of the sliding rod, so that the movable plate can contact the inner wall of the casing and scrape off the powder adhering to the inner wall of the casing.

[0010] Preferably, the inner wall of the movable plate has a through groove, the slide rod is slidably connected to the inner wall of the groove, one end of the spring is fixedly connected to the movable plate, and the other end of the spring is fixedly connected to the inner wall of the fixed plate. The spring can always push the movable plate to move towards the inner wall of the storage sleeve.

[0011] Preferably, the end of the movable plate away from the fixed plate is in contact with the inner wall of the storage sleeve, and there is a gap between the lower outer wall of the fixed plate and the filter screen. The movable plate is always in contact with the inner wall of the storage sleeve, and when the storage sleeve rotates, the movable plate can scrape the powder off the inner wall of the storage sleeve.

[0012] Preferably, the center of the limiting plate is located away from the center of the toothed ring and the vertical line of the filter screen, and the outer wall of one end of the storage sleeve is attached to the inner wall of the movable groove, so that the rotating motor can make the gear rotate, causing the toothed ring meshing with it to rotate, thereby making the storage sleeve rotate.

[0013] Preferably, the toothed ring is rotatably connected to the inner wall of the sleeve, and the opening of the toothed ring is larger than the opening of the sleeve, so that when the storage sleeve rotates, the powder can always fall into the storage sleeve when the powder is fed.

[0014] Preferably, the direction in which the feeding motor drives the gear to rotate is opposite to the direction in which the rotating motor drives the transmission shaft to rotate, so that when the storage sleeve rotates, the moving plate can better scrape the inner wall of the storage sleeve.

[0015] Compared with the prior art, the present invention provides an epoxy molding compound powder dispersion and extrusion device, which has the following beneficial effects:

[0016] 1. The epoxy molding compound powder dispersion and extrusion device drives the gear to rotate by rotating the motor, which in turn rotates the meshing gear ring and drives the receiving sleeve to rotate. The center of the receiving sleeve and the center of the gear ring are not located on the same vertical line of the filter screen. This allows the receiving sleeve to generate centrifugal force on the powder when it rotates with the gear ring, so that the plastic powder inside can be dispersed and sprinkled out, preventing the powder from agglomerating and forming clumps.

[0017] 2. The epoxy molding compound powder dispersion and extrusion device uses a spring to continuously push the moving plate toward the inner wall of the storage sleeve, so that the moving plate is always in contact with the inner wall of the storage sleeve. When the storage sleeve rotates, the moving plate can scrape the powder off the inner wall of the storage sleeve, so that the powder can fall off fully. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an epoxy molding compound powder dispersion extrusion device, including a sleeve 1, an inlet 2 fixedly connected to the upper outer wall of the sleeve 1, a connecting plate 3 fixedly connected to the outer wall of the sleeve 1, a feeding motor 4 fixedly connected to the end of the connecting plate 3 away from the sleeve 1, a drive shaft 5 fixedly connected to the output end of the feeding motor 4, a spiral auger 6 fixedly connected to the outer wall of the drive shaft 5, and a dispersion component 7 arranged inside the sleeve 1. The dispersion component 7 includes a housing 71, a rotating motor 72, a gear 73, a gear ring 74, a limiting plate 75, a storage sleeve 76, a filter screen 77, and a movable groove 78.

[0024] In one embodiment of the present invention, the housing 71 is fixedly connected to the outer wall of the sleeve 1, the inner wall of the housing 71 is fixedly connected to a rotating motor 72, the output end of the rotating motor 72 is fixedly connected to a gear 73, and the outer wall of the gear 73 is meshed with a toothed ring 74.

[0025] In one embodiment of the present invention, a limiting plate 75 is fixedly connected to the outer wall of a toothed ring 74, a storage sleeve 76 is fixedly connected to the lower outer wall of the limiting plate 75, a filter screen 77 is fixedly connected to the lower outer wall of the storage sleeve 76, and a movable groove 78 is provided on the inner wall of the housing 71.

[0026] In addition, the casing 71 is equipped with a material feeding assembly 8. The material feeding assembly 8 includes a fixed plate 81, which is fixedly connected to the lower outer wall of the drive shaft 5. A movable plate 82 is slidably connected to the inner wall of the fixed plate 81, and a slide rod 83 is fixedly connected to the inner wall of the fixed plate 81. A spring 84 is sleeved on the outer wall of the slide rod 83, so that the movable plate 82 can contact the inner wall of the storage sleeve 76, so that the movable plate 82 can scrape off the powder adhering to the inner wall of the storage sleeve 76, so that the powder can be fully fed out.

[0027] In an embodiment of this utility model, the inner wall of the movable plate 82 is provided with a through groove, the slide rod 83 is slidably connected to the inner wall of the groove, one end of the spring 84 is fixedly connected to the movable plate 82, and the other end of the spring 84 is fixedly connected to the inner wall of the fixed plate 81. The spring 84 can always push the movable plate 82 to move towards the inner wall of the storage sleeve 76.

[0028] In this embodiment of the utility model, the end of the movable plate 82 away from the fixed plate 81 is attached to the inner wall of the storage sleeve 76, and there is a gap between the lower outer wall of the fixed plate 81 and the filter screen 77. The movable plate 82 is always attached to the inner wall of the storage sleeve 76. When the storage sleeve 76 rotates, the movable plate 82 can scrape the powder off the inner wall of the storage sleeve 76. The fixed plate 81 is at a distance from the filter screen 77 so that the fixed plate 81 will not affect the powder falling off the filter screen 77.

[0029] In this embodiment of the utility model, the center of the limiting plate 75 is far from the vertical line between the center of the toothed ring 74 and the filter screen 77. One end of the outer wall of the storage sleeve 76 is attached to the inner wall of the movable groove 78, so that the rotating motor 72 can make the gear 73 rotate, causing the toothed ring 74 that meshes with it to rotate, thereby making the storage sleeve 76 rotate. Moreover, the center of the storage sleeve 76 and the center of the toothed ring 74 are not located on the same vertical line of the filter screen 77, so that the storage sleeve 76 can disperse and sprinkle out the internal plastic powder when it rotates.

[0030] In an embodiment of this utility model, the toothed ring 74 is rotatably connected to the inner wall of the housing 71. The opening of the toothed ring 74 is larger than the opening of the sleeve 1, so that when the receiving sleeve 76 rotates, the powder can always fall into the receiving sleeve 76 when the powder is fed, and the receiving sleeve 76 can always disperse the powder from the filter screen 77.

[0031] In this embodiment of the utility model, the direction in which the feeding motor 4 drives the gear 73 to rotate is opposite to the direction in which the rotating motor 72 drives the transmission shaft 5 to rotate. This allows the moving plate 82 to better scrape the inner wall of the storage sleeve 76 when the storage sleeve 76 rotates, thus scraping off the powder on the inner wall of the storage sleeve 76 and allowing the powder to fall off fully.

[0032] In this invention, during use, powder is poured in through the inlet 2. Then, the feeding motor 4 drives the transmission shaft 5 to rotate, causing the auger 6 to rotate and transport the powder down. At this time, the rotating motor 72 drives the gear 73 to rotate, causing the meshing gear ring 74 to rotate, thereby causing the receiving sleeve 76 to rotate. The center of the receiving sleeve 76 and the center of the gear ring 74 are not located on the same vertical line of the filter screen 77, so that the receiving sleeve 76 can generate centrifugal force when rotating, dispersing the plastic powder inside and sprinkling it out. This ensures that the plastic powder can be fully dispersed, preventing the powder from agglomerating and forming clumps. The spring 84 can always push the moving plate 82 towards the inner wall of the receiving sleeve 76, so that the moving plate 82 is always in contact with the inner wall of the receiving sleeve 76. When the receiving sleeve 76 rotates, the moving plate 82 can scrape the powder off the inner wall of the receiving sleeve 76, allowing the powder to fall down fully.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
