[0001] The present application relates to the technical field of packaging equipment, in particular to a transmission device convenient to disassemble and assemble. BACKGROUND

[0002] In the process of semiconductor packaging, the exposed chip is encapsulated and protected by epoxy resin (EMC) under the action of pressure and temperature through a mold. Epoxy resin has good insulation and chemical resistance, which can effectively protect the chip from the influence of external environment such as moisture, ion contamination, heat, radiation and mechanical stress, so as to protect the chip from the invasion of external environment, thereby ensuring the performance and stability of the chip.

[0003] In the packaging process, epoxy resin needs to be loaded into the lower mold cavity of the mold through a resin transmission groove. However, the cover plate of the resin transmission groove for transmitting epoxy resin is fixed by screws at present, which is more troublesome to disassemble and assemble, and there may be the phenomenon that the inside of the resin transmission groove is not completely cleaned. If the residual resin is not cleaned completely, it will cause mixing of different resins or expired resins, which will cause a series of packaging problems such as arc abnormality, delamination abnormality, and even cause product function failure.

[0028] The feeding port 10 is arranged at one end of the conveying groove 20 and communicates with the conveying groove 20. The feeding port 10 is used for feeding, and the material such as epoxy resin enters the conveying groove 20 through the feeding port 10. The cross section of the feeding port 10 can be trapezoidal, and the width of the opening of the feeding port 10 can gradually decrease towards the conveying groove 20 (that is, from top to bottom in the direction of the conveying groove 20). In other embodiments, the feeding port 10 can also be funnel-shaped, frustum-shaped, or the like, which are not limited in the present application. Figure 1

[0029] The conveying groove 20 communicates with the feeding port 10, and the material (for example, epoxy resin) entering from the feeding port 10 enters the conveying groove 20. The conveying groove 20 is provided with a plurality of clamping portions 40, and each clamping portion 40 includes a first part 41 and a second part 42 connected to each other. The first part 41 is fixed to the conveying groove 20, and the second part 42 is connected to the first part 41 and protrudes from the surface of the conveying groove 20 towards the feeding port 10. That is, the second part 42 is higher than the surface of the conveying groove 20 towards the feeding port 10.

[0030] The cover plate 30 is arranged on the surface of the conveying groove 20 towards the feeding port 10 and is slidably connected to the conveying groove 20. That is, the cover plate 30 can slide on the conveying groove 20. In particular, the cover plate 30 can move on the conveying groove 20 along the extension direction of the conveying groove 20 (that is, the horizontal direction in the conveying groove 20), and the extension direction of the conveying groove 20 can be parallel to the extension direction of the cover plate 30. The cover plate 30 is inserted into the space formed by the first part 41 and the second part 42. The space formed by the first part 41 and the second part 42 is equivalent to a clamping groove structure, and the cover plate 30 is not completely fixed on the conveying groove 20, but can be limited by the clamping portion 40 to move in the clamping groove structure, which ensures that the cover plate 30 can move along the extension direction of the conveying groove 20 without deviation when the cover plate 30 moves, and also blocks the movement of the cover plate 30 in the vertical direction (that is, the vertical direction in the conveying groove 20, the height direction of the conveying groove 20). Figure 1 Figure 1

[0031] ​​​By setting the clamping part 40 (including the first part 41 and the second part 42, and the first part 41 and the second part 42 form a clamping groove structure) on the conveying groove 20, and inserting the cover plate 30 into the clamping groove structure of the clamping part 40, the cover plate 30 can be fixed on the conveying groove 20, and the cover plate 30 can also slide on the conveying groove 20. When it is necessary to clean the materials in the conveying groove 20, the cover plate 30 can be pulled out by sliding along the conveying groove 20; when it is necessary to cover the cover plate 30, the cover plate 30 can be inserted into the clamping part 40. Compared with the way of fixing the cover plate on the conveying groove by screws, the cover plate 30 of the conveying device 100 of the present application is convenient to disassemble and assemble, so as to facilitate the cleaning of the residual materials in the conveying groove 20.

[0032] In some embodiments, as shown in Figure 1 and Figure 3 The conveying groove 20 is substantially a hollow cuboid structure, which includes a bottom plate 21, and a first side plate 22, a second side plate 23 and a third side plate 24 arranged on the bottom plate 21. The cavity formed by the bottom plate 21, the first side plate 22, the second side plate 23 and the third side plate 24 can contain materials (for example, epoxy resin). The first side plate 22 and the third side plate 24 are arranged opposite to each other and can be arranged in parallel. The second side plate 23 is connected with the first side plate 22 and the third side plate 24 at both ends thereof. The feeding port 10 is arranged on the first side plate 22 and the third side plate 24 away from the second side plate 23, and the cover plate 30 is arranged on the first side plate 22 and the third side plate 24 away from the bottom plate 21.

[0033] Further, the conveying groove 20 can further include a fourth side plate 25 arranged on the bottom plate 21. The fourth side plate 25 is arranged on the end of the bottom plate 21 away from the second side plate 23 and is arranged opposite to the second side plate 23. The feeding port 10 is arranged on the fourth side plate 25 close to the second side plate 23.

[0034] In some embodiments, as shown in Figure 1 and Figure 3As shown, some of the clamping portions 40 are arranged on the first side plate 22, and some of the clamping portions 40 are arranged on the third side plate 24. In the embodiment, the number of the clamping portions 40 arranged on the first side plate 22 is equal to the number of the clamping portions 40 arranged on the third side plate 24, and both are three; in other embodiments, the number of the clamping portions 40 arranged on the first side plate 22 is not equal to the number of the clamping portions 40 arranged on the third side plate 24. The number of the clamping portions 40 arranged on the first side plate 22 and the third side plate 24 can be adjusted according to actual conditions, and the present application does not make any limitation. The first part 41 of the clamping portion 40 can be fixed on the first side plate 22 or the third side plate 24 by means of welding, adhesion, but not limited to, and the extending direction of the first part 41 is substantially parallel to the height direction of the first side plate 22 or the third side plate 24. The second part 42 is connected to the end of the extending direction of the first part 41, and is substantially perpendicular to the first part 41. The second part 42 can extend along the arrangement direction of the first side plate 22 and the third side plate 24. As shown in FIG. 1, the second part 42 of the clamping portion 40 arranged on the first side plate 22 is arranged on the third side plate 24, and the second part 42 of the clamping portion 40 arranged on the third side plate 24 is arranged on the first side plate 22. Figure 2 As shown, the cross section of the clamping portion 40 can be inverted "L" shape.

[0035] Further, the first part 41 and the second part 42 can be integrally formed, and the first part 41 and the second part 42 can also be formed by means of separate welding.

[0036] Further, the material of the first part 41 and the second part 42 can be metal, preferably metal material which is not easy to deform, such as titanium alloy, stainless steel, chromium, etc. In this way, the high strength and stability of the clamping portion 40 can be ensured, and the sliding of the cover plate 30 can also be facilitated (the friction coefficient of metal is smaller).

[0037] As shown in some embodiments, Figure 1 and Figure 3 The clamping portions 40 on the first side plate 22 and the clamping portions 40 on the third side plate 24 are symmetrically arranged. The symmetry arrangement means that the orthographic projection of each clamping portion 40 on the first side plate 22 on the third side plate 24 has at least a part of the clamping portion 40 on the third side plate 24 which overlaps with the orthographic projection, preferably exactly overlaps; the orthographic projection of each clamping portion 40 on the third side plate 24 on the first side plate 22 has at least a part of the clamping portion 40 on the first side plate 22 which overlaps with the orthographic projection, preferably exactly overlaps. In other embodiments, the clamping portions 40 on the first side plate 22 and the clamping portions 40 on the third side plate 24 can also be staggered. That is, the orthographic projection of each clamping portion 40 on the first side plate 22 on the third side plate 24 does not overlap with each clamping portion 40 on the third side plate 24; the orthographic projection of each clamping portion 40 on the third side plate 24 on the first side plate 22 does not overlap with each clamping portion 40 on the first side plate 22.

[0038] As shown in some embodiments, Figure 2As shown, along the height direction of the first side plate 22 or the third side plate 24 (i.e.) Figure 2 The distance between the surface of the second part 42 facing the first side plate 22 (or the third side plate 24) (i.e., the bottom surface of the second part 42) and the surface of the first side plate 22 (or the third side plate 24) facing the second part 42 is equal to the thickness of the cover plate 30. In this way, the cover plate 30 fits perfectly into the snap-fit ​​part 40, ensuring the vertical stability of the cover plate 30.

[0039] In other embodiments, along the height direction of the first side plate 22 or the third side plate 24 (i.e. Figure 2 The distance between the surface of the second part 42 facing the first side plate 22 (or the third side plate 24) (i.e., the bottom surface of the second part 42) and the surface of the first side plate 22 (or the third side plate 24) facing the second part 42 is slightly greater than the thickness of the cover plate 30 (for example, the extra distance can be within 5% of the thickness of the cover plate 30). Thus, there is a certain gap between the cover plate 30 and the second part 42 in the vertical direction, allowing the cover plate 30 to be pulled out or inserted more smoothly.

[0040] In some embodiments, the cover plate 30 may be a transparent acrylic plate to facilitate observation of the material in the transfer channel 20.

[0041] The transmission device 100 provided in this application embodiment, by providing a snap-fit ​​part 40 (including a first part 41 and a second part 42, wherein the first part 41 and the second part 42 form a snap-fit ​​structure) on the transmission groove 20, and inserting the cover plate 30 into the snap-fit ​​structure of the snap-fit ​​part 40, can both fix the cover plate 30 on the transmission groove 20 and allow the cover plate 30 to slide on the transmission groove 20. When it is necessary to clean the material inside the transmission groove 20, simply slide the cover plate 30 out along the transmission groove 20; when it is necessary to close the cover plate 30, simply insert the cover plate 30 into the snap-fit ​​part 40. Compared with the method of fixing the cover plate to the transmission groove with screws, the cover plate 30 of the transmission device 100 of this application is easy to disassemble and assemble, thereby facilitating the cleaning of residual material inside the transmission groove 20.

[0042] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
