Abstract
Description
Technical Field
[0001] This utility model relates to the field of epoxy molding compound processing technology, specifically to a treatment device for preventing epoxy molding compound powder from agglomerating. Background Technology
[0002] Epoxy molding compound is a thermosetting plastic, meaning that the resin can be cured by increasing temperature and pressure. Once fully cured, the product cannot be re-heated and therefore cannot be remelted. This product can be used for chip packaging and integrated circuit packaging. In actual production and use, epoxy molding compound powder is prone to clumping due to factors such as moisture, pressure, and prolonged storage. Clumped epoxy molding compound powder has poor flowability, making it difficult to mix and mold evenly, which affects subsequent processing and leads to a decline in product quality.
[0003] Common processing methods often involve manual intervention, such as manual stirring and breaking up clumps. However, this method is inefficient, labor-intensive, and difficult to guarantee the uniformity and thoroughness of the processing. Some factories use simple stirring equipment for processing, but these devices can only perform a single stirring action and cannot effectively solve the clumping caused by fundamental problems such as moisture in the powder. They cannot fundamentally prevent epoxy molding compound powder from clumping and cannot meet the needs of large-scale industrial production. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a device for preventing epoxy molding compound powder from agglomerating, which has the advantage of high efficiency in preventing agglomeration and solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a treatment device for preventing epoxy molding compound powder from agglomerating, comprising a shell, wherein the shell contains a crushing component for breaking up agglomerates and a drying component for drying epoxy molding compound powder. The crushing component includes a sieve cylinder disposed inside the shell, a first toothed ring fixed to the top of the sieve cylinder, and multiple sets of first crushing rollers for crushing fixed to the inner wall of the sieve cylinder. The drying component includes an inner cylinder disposed below the sieve cylinder, wherein a heating tube is wound around the outer surface of the inner cylinder, and the heating tube is connected to an external heating device.
[0006] Furthermore, a rotating rod is rotatably connected to the inner bottom wall of the screen cylinder, the rotating rod passes through the screen cylinder, and multiple sets of second crushing rollers are fixed on the outer surface of the rotating rod, the second crushing rollers being arranged alternately with the first crushing rollers.
[0007] The above scheme allows the rotation of the rotating rod to drive the second crushing roller to rotate, which in turn drives the rotation of the screen cylinder to drive the first crushing roller to rotate. The first and second crushing rollers then crush the agglomerated material.
[0008] Furthermore, a first gear is rotatably connected to the inner top wall of the outer casing, the first gear meshes with a first gear ring, and a first motor is mounted on the upper surface of the outer casing, with the output end of the first motor connected to the first gear.
[0009] The above scheme involves a first motor driving a first gear to rotate, which in turn drives a first gear ring to rotate, and the rotation of the first gear ring drives the screen cylinder to rotate.
[0010] Furthermore, multiple support plates are fixed to the inner wall of the outer shell, and the sieve cylinder is placed on the upper surface of the support plates.
[0011] The above solution uses a support plate to provide auxiliary support for the screen cylinder.
[0012] Furthermore, multiple support arms are fixed to the outer surface of the rotating rod, and a second gear is rotatably connected to the bottom surface of the support arms. A second gear ring is fixed to the inner wall of the outer casing, and the second gear meshes with the second gear ring.
[0013] The above scheme uses a rotating rod to drive the support arm to rotate, which in turn drives the second gear to revolve. Simultaneously, through the meshing of the second gear and the second gear ring, the second gear rotates on its own axis while revolving around the center of the orbit.
[0014] Furthermore, a third gear corresponding to the second gear is provided between each of the second gears and the rotating rod. The third gear is rotatably connected to the support arm, and the third gear meshes with the corresponding second gear.
[0015] The above scheme allows the rotation of the second gear to drive the rotation of the third gear.
[0016] Furthermore, a driven rod is fixed to the bottom surface of the third gear, and an auger is fixed to the outer surface of the driven rod.
[0017] The above scheme uses the rotation of the third gear to drive the auger to rotate, which in turn causes the material inside the inner cylinder to move fully, thus ensuring that the material is heated evenly.
[0018] Furthermore, a discharge port is provided on the bottom surface of the outer casing, a discharge plate is fixed on the side of the rotating rod, and a second motor is installed on the bottom surface of the outer casing, with the output end of the second motor connected to the rotating rod.
[0019] The above scheme enables the output of the second motor to drive the rotating rod to rotate.
[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0021] This device for preventing epoxy molding compound powder from caking involves a crushing component that crushes the material entering the screen cylinder. Material of the correct volume falls through the screen cylinder into the inner cylinder, where a heating element heats the inner cylinder. An auger moves the epoxy molding compound powder inside the inner cylinder, ensuring the powder is heated evenly and thus drying the powder, achieving efficient anti-caking.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a device for preventing epoxy molding compound powder from agglomerating includes a housing 1. Inside the housing 1 are a crushing component 2 for breaking up agglomerates and a drying component 3 for drying epoxy molding compound powder. The crushing component 2 includes a sieve cylinder 201 disposed inside the housing 1. A first toothed ring 202 is fixed to the top of the sieve cylinder 201. Multiple sets of first crushing rollers 203 for crushing are fixed to the inner wall of the sieve cylinder 201. The drying component 3 includes an inner cylinder 301 disposed below the sieve cylinder 201. A heating tube 302 is wound around the outer surface of the inner cylinder 301. The heating tube 302 is connected to an external heating device.
[0033] Please see Figure 2 , Figure 3 and Figure 4 A rotating rod 4 is rotatably connected to the inner bottom wall of the screen cylinder 201. The rotating rod 4 passes through the screen cylinder 201. Multiple sets of second crushing rollers 204 are fixed to the outer surface of the rotating rod 4. The second crushing rollers 204 and the first crushing rollers 203 are arranged alternately. The rotation of the rotating rod 4 can drive the second crushing rollers 204 to rotate, which in turn drives the first crushing rollers 203 to rotate. The first crushing rollers 203 and the second crushing rollers 204 crush the agglomerated material. A first gear 205 is rotatably connected to the inner top wall of the outer shell 1. The first gear 205 meshes with the first gear ring 202. A first motor 206 is installed on the upper surface of the outer shell 1. The output end of the first motor 206 is connected to the first gear 205. The first motor 206 drives the first gear 205 to rotate, which in turn drives the first gear ring 202 to rotate. The rotation of the first gear ring 202 drives the screen cylinder 201 to rotate.
[0034] Please see Figure 2 , Figure 3 and Figure 4 Multiple support plates 5 are fixed to the inner wall of the outer shell 1. The screen cylinder 201 is placed on the upper surface of the support plate 5. The support plate 5 provides auxiliary support for the screen cylinder 201. Multiple support arms 303 are fixed to the outer surface of the rotating rod 4. The bottom surface of the support arm 303 is rotatably connected to the second gear 304. The inner wall of the outer shell 1 is fixed with the second gear ring 305. The second gear 304 meshes with the second gear ring 305. The rotating rod 4 drives the support arm 303 to rotate. The support arm 303 drives the second gear 304 to revolve. At the same time, through the meshing of the second gear 304 and the second gear ring 305, the second gear 304 rotates on its own axis while revolving.
[0035] Please see Figure 2 , Figure 3 and Figure 4Each second gear 304 is connected to a third gear 306 corresponding to the second gear 304 between it and the rotating rod 4. The third gear 306 is rotatably connected to the support arm 303. The third gear 306 meshes with the corresponding second gear 304. The rotation of the second gear 304 drives the third gear 306 to rotate. A driven rod 307 is fixed to the bottom surface of the third gear 306. An auger 308 is fixed to the outer surface of the driven rod 307. The rotation of the third gear 306 drives the auger 308 to rotate. The rotation of the auger 308 allows the material inside the inner cylinder 301 to move fully, thereby making the material heat evenly. A discharge port is opened on the bottom surface of the outer shell 1. A discharge plate 6 is fixed to the side of the rotating rod 4. A second motor 7 is installed on the bottom surface of the outer shell 1. The output end of the second motor 7 is connected to the rotating rod 4. The output end of the second motor 7 drives the rotating rod 4 to rotate.
[0036] It should be noted that one side of the discharge plate 6 is inclined. When the crushing and drying operation is carried out, the rotating rod 4 rotates forward, and the inclined surface of the discharge plate 6 contacts the material, which facilitates the movement of the discharge plate 6. When discharging, the second motor 7 is turned off first, the discharge port is opened, and the material is discharged by gravity. After the material stops being discharged, the second motor 7 is started and reversed. The discharge plate 6 reverses and pushes the remaining material inside the inner cylinder 301 out of the discharge port.
[0037] The working principle of the above embodiment is as follows: First, epoxy molding compound powder is added to the sieve cylinder 201. The unagglomerated epoxy molding compound powder falls directly into the inner cylinder 301 through the sieve cylinder 201. Then, the first motor 206 is started. The first motor 206 drives the first gear 205 to rotate, which in turn drives the first gear ring 202 to rotate. The rotation of the first gear ring 202 drives the sieve cylinder 201 to rotate. At the same time, the second motor 7 and the external heating device are started. The second motor 7 drives the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the second crushing roller 204 to rotate. The second crushing roller 204, together with the first crushing roller 203 driven by the sieve cylinder 201, crushes the agglomerated epoxy molding compound powder inside the sieve cylinder 201. Epoxy molding compound powder that meets the volume requirements enters the inner cylinder 301 through the sieve cylinder 201. Epoxy molding compound powder that does not meet the requirements is continuously crushed inside the sieve cylinder 201.
[0038] Heating tube 302 is heated by an external heating device, which in turn heats the inner cylinder 301. Rotating rod 4 drives support arm 303 to rotate, which in turn drives second gear 304 to rotate. The rotation of second gear 304 drives third gear 306 to rotate, which in turn drives auger 308 to rotate. The rotation of auger 308 causes the material inside the inner cylinder 301 to move fully, thereby ensuring that the epoxy molding compound powder inside the inner cylinder 301 is heated evenly, completing the drying of the epoxy molding compound powder. Then, the discharge port is opened to complete the discharge operation.
