For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] The chip encapsulation equipment in the prior art does not have a resin posture screening device, and cannot screen out the resin with a longitudinal axis, which is not convenient for subsequent production and processing.

[0060] The following is a preferred embodiment of a resin posture screening device and a chip plastic packaging device provided by the utility model that can solve the above technical problems.

[0061] Please refer to Figure 1 The preferred embodiment of the utility model provides a chip encapsulation device, which includes a resin posture screening device 1, a hopper 2 and a feeding mechanism 3.

[0062] Please refer to Figure 2 and Figure 3 The resin posture screening device 1 includes a fixed frame 11, a transmission component 12 and a longitudinal screening block 13. The fixed frame 11 includes a vertical plate 111, and the vertical plate 111 is arranged in the horizontal direction. The transmission component 12 includes an annular transmission belt 121 and a driving component 122. The transmission belt 121 is located on one longitudinal side of the vertical plate 111, and is used to transmit the resin in the horizontal direction. The transmission direction of the transmission belt 121 includes an upper material position and a lower material position arranged in the horizontal direction. The driving component 122 is fixed to the fixed frame 11 and connected to the transmission belt 121, and is used to drive the transmission belt 121 to rotate so as to transmit the resin from the upper material position to the lower material position.

[0063] Please refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9 The longitudinal screening block 13 includes a longitudinal screening portion 131 and a longitudinal connecting portion 132 arranged in the longitudinal direction. The longitudinal connecting portion 132 is connected to the vertical plate 111. The longitudinal screening portion 131 extends above one longitudinal side of the conveyor belt 121 and is located between the upper material position and the lower material position. An inclined guide surface 1311 is provided on the side of the longitudinal screening portion 131 close to the upper material position, and the end of the guide surface 1311 facing away from the vertical plate 111 is inclined toward the direction close to the lower material position. An inclined avoidance surface 1312 is provided on the top of the longitudinal screening portion 131, and the end of the avoidance surface 1312 facing away from the vertical plate 111 is inclined toward the direction close to the conveyor belt 121. The longitudinal screening portion 131 is used to push the resin with a longitudinal axis away from the conveyor belt 121.

[0064] Please refer to Figure 1 The hopper 2 is used for placing resin, and is located on the side of the conveyor belt 121 facing away from the standing plate 111 .

[0065] The feeding mechanism 3 is located between the hopper 2 and the conveyor belt 121 , and is used for feeding the resin in the hopper 2 to the conveyor belt 121 .

[0066] In the resin posture screening device 1 and chip encapsulation equipment of the utility model, after the resin is located at the upper material position, the conveyor belt 121 moves the resin from the upper material position to the lower material position. When the resin with a horizontal axis passes through the longitudinal screening part 131, the avoidance surface 1312 avoids one side of the longitudinal direction of the resin, so that it can pass through the longitudinal screening block 13 smoothly. When the resin with a longitudinal axis passes through the longitudinal screening part 131, the guide surface 1311 guides the end of the resin to continue to move in the direction close to the lower material position. When the resin moves to the end of the longitudinal screening part 131, the resin loses its center of gravity and falls from the side of the conveyor belt 121 away from the vertical plate 111. In the resin posture screening device 1 and chip encapsulation equipment of the utility model, the resin with a longitudinal axis can be pushed away from the conveyor belt 121 by the longitudinal screening block 13, so that the resin with a horizontal axis can pass smoothly, which is convenient for subsequent production and processing.

[0067] Please refer to Figure 7 and Figure 8 , a through slot 1111 is provided on the vertical plate 111. The fixing frame 11 also includes a first connecting piece 112, the cross section of which is L-shaped, and is connected to the vertical plate 111 and the longitudinal connecting portion 132. The longitudinal screening block 13 is provided in the through slot 1111, and the longitudinal connecting portion 132 is provided with a first strip hole 1321 extending in the longitudinal direction, and the first strip hole 1321 is used for screws to pass through to connect the first connecting piece 112 and the longitudinal connecting portion 132. With the above structure, the position of the longitudinal screening block 13 in the through slot 1111 can be adjusted along the first strip hole 1321 according to the diameter of the resin. If the diameter of the resin is large, the part of the longitudinal screening portion 131 extending above the conveyor belt 121 can be adjusted to be smaller, so that the resin with a horizontal axis can pass smoothly; if the diameter of the resin is small, the part of the longitudinal screening portion 131 extending above the conveyor belt 121 can be adjusted to be larger, so that the resin with a longitudinal axis can be pushed down smoothly.

[0068] Please refer to Fig.10 and Fig.11The resin posture screening device 1 also includes a vertical screening plate 14, which includes a vertical screening part 141 and a vertical connecting part 142. The vertical connecting part 142 is connected to the vertical plate 111. The vertical screening part 141 is vertically connected to the top of the vertical connecting part 142, which extends to the top of the other longitudinal side of the conveyor belt 121, and is located between the longitudinal screening part 131 and the discharge position, and the vertical screening part 141 is higher than the longitudinal screening part 131. The vertical screening part 141 is provided with an inclined guide edge 1411 on one side of the vertical screening part 131, and the end of the guide edge 1411 away from the vertical plate 111 is inclined toward the direction close to the discharge position. When the axial direction of the resin is horizontal, it can pass smoothly from the bottom of the vertical screening part 141 when passing through the vertical screening part 141. When the axis of the resin is vertical, when it passes through the vertical screening part 141, it moves along the guide edge 1411 in the direction away from the vertical plate 111, and finally falls from the side of the conveyor belt 121 away from the vertical plate 111; when two resins with horizontal axes are stacked vertically, the resin located above moves along the guide edge 1411 in the direction away from the vertical plate 111, and finally falls from the side of the conveyor belt 121 away from the vertical plate 111, and the resin located below passes smoothly.

[0069] Please refer to Fig.11 The vertical connection part 142 is provided with a second strip hole 1421 extending in the vertical direction, and the second strip hole 1421 is used for screws to pass through to connect the vertical connection part 142 and the vertical plate 111. With the above structure, the position of the vertical screening piece 14 can be adjusted along the second strip hole 1421 according to the diameter of the resin. When the diameter of the resin is large, the vertical screening part 141 can be adjusted to be farther away from the conveyor belt 121, so that the resin below can pass smoothly; when the diameter of the resin is small, the vertical screening part 141 can be adjusted to be closer to the conveyor belt 121, so that the resin above can be pushed down smoothly.

[0070] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.12The fixing frame 11 also includes a tilt adjustment plate 113, which includes a main plate 1131, a middle strip 1132 and a tilt adjustment strip 1133. The main plate 1131 is fitted and connected to the side of the vertical plate 111 close to the conveyor belt 121. The middle strip 1132 extends in the horizontal direction, one side of which is connected to the top edge of the main plate 1131, and the middle strip 1132 is arranged in the area surrounded by the conveyor belt 121. One side of the tilt adjustment strip 1133 is connected to the other side of the middle strip 1132, and the tilt adjustment strip 1133 extends in the horizontal direction, and is located between the vertical screening plate 14 and the material discharge position. The top of the tilt adjustment strip 1133 is tilted away from the vertical plate 111, and the end of the tilt adjustment strip 1133 facing the vertical screening plate 14 is tilted, and the top of the tilt adjustment strip is tilted in the direction close to the material discharge position. When the resin is in a horizontal direction, when it passes through the tilt adjustment strip 1133, the top of the tilt adjustment strip 1133 is tilted away from the vertical plate 111, so that the resin in this posture can be avoided and passed smoothly; when the resin is in an inclined state, the end of the tilt adjustment strip 1133 facing the vertical screening plate 14 is tilted, and its top is tilted toward the direction close to the material discharge position, so that the resin in this posture can be guided to make its axis in the horizontal direction. Figure 3 As shown, when the rear end of the resin is tilted toward the vertical plate 111, the front end of the resin can move toward the top of the tilt adjustment bar 1133 when the resin moves forward with the conveyor belt 121, and after moving a certain distance, the front end of the resin can roll down from the top to the conveyor belt 121, thereby straightening the resin. Figure 5 As shown, when the front end of the resin is tilted toward the vertical plate 111, the rear end of the resin can move toward the top of the tilt adjustment strip 1133 as the resin moves forward with the conveyor belt 121. After moving a certain distance, the rear end of the resin rolls from the top to the conveyor belt 121, thereby straightening the resin. Figure 3 and Figure 5 The resin near the tilt adjustment bar 1133 shown in the figure has different tilt directions. No matter which direction the resin tilts, the tilt adjustment bar 1133 can adjust the resin so that the axial direction is horizontal.

[0071] Please refer to Figure 2 and Fig.13, the fixing frame 11 also includes a second connecting piece 114, which is connected to one end of the main plate 1131 near the upper material position. A third long hole 11311 extending in the transverse direction is provided at one end of the main plate 1131 near the upper material position, which is used for screws to pass through to connect the main plate 1131 and the second connecting piece 114. The transmission component 12 includes a driving wheel 1221 and a plurality of driven wheels 1222, and the transmission belt 121 is sleeved on the driving wheel 1221 and the plurality of driven wheels 1222. The plurality of driven wheels 1222 are divided into two groups, one group of driven wheels 1222 is connected to one end of the vertical plate 111 near the lower material position, and the other group of driven wheels 1222 is connected to the second connecting piece 114. With the above structure, the position of the second connecting piece 114 can be adjusted along the third long hole 11311, thereby adjusting the distance between the two groups of driven wheels 1222, and then adjusting the tightness of the transmission belt 121.

[0072] Please refer to Figure 3 , the top edge of the vertical plate 111 is higher than the conveyor belt 121. With this structure, the resin on the conveyor belt 121 can be prevented from falling from the side close to the vertical plate 111.

[0073] Please refer to Figure 1 The hopper 2 includes a first side plate 21, a second side plate 22, a third side plate 23 and a bottom plate 24. The first side plate 21, the second side plate 22, the third side plate 23 and the feeding mechanism 3 are surrounded by a square cylinder, and the bottom plate 24 is connected to the bottoms of the first side plate 21, the second side plate 22 and the third side plate 23. The second side plate 22 and the feeding mechanism 3 are arranged in the longitudinal direction, and the feeding mechanism 3 is close to the conveyor belt 121 relative to the second side plate 22. The first side plate 21 and the third side plate 23 are arranged in the transverse direction, and the first side plate 21 is close to the unloading position relative to the third side plate 23. A first step 211 and a second step 212 are provided on the side of the first side plate 21 facing the third side plate 23. The first step 211 and the second step 212 are arranged in the longitudinal direction. The second step 212 is closer to the second side plate 22 relative to the first step 211. The first step 211 is higher than the second step 212. Both the first step 211 and the second step 212 are inclined. The first step 211 gradually decreases from an end away from the second side plate 22 to an end close to the second side plate 22. The second step 212 gradually decreases from a side away from the third side plate 23 to a side close to the third side plate 23. A baffle 213 is provided on the side of the first step 211 close to the third side plate 23. When the resin falls from the conveyor belt 121, it first falls on the first step 211, slides along the first step 211 toward the second side plate 22, then falls on the second step 212, slides along the second step 212 toward the third side plate 23, and finally falls on the bottom plate 24, so that it can be re-transported to the conveyor belt 121 by the feeding mechanism 3. With the above structure, the resin can be buffered to prevent it from breaking.

[0074] Please refer to Figure 1 The feeding mechanism 3 includes a first feeding plate 31, a second feeding plate 32 and a third feeding plate 33 arranged in parallel along the longitudinal direction. The first feeding plate 31 is closer to the second side plate 22 relative to the third feeding plate 33. The tops of the three are all inclined, and the sides of the tops of the three away from the second side plate 22 are inclined toward the direction close to the conveyor belt 121. The second feeding plate 32 is fixedly arranged, and the first feeding plate 31 and the third feeding plate 33 are both vertically slidable. When the first feeding plate 31 moves from a position lower than the second feeding plate 32 to a position higher than the second feeding plate 32, the resin rolls from the first feeding plate 31 to the second feeding plate 32; when the third feeding plate 33 slides from a position higher than the second feeding plate 32 to a position lower than the second feeding plate 32, the resin rolls from the second feeding plate 32 to the third feeding plate 33; when the third feeding plate 33 moves from a position lower than the conveyor belt 121 to a position higher than the conveyor belt 121, the resin slides from the third feeding plate 33 to the conveyor belt 121. The resin can be smoothly loaded onto the conveyor belt 121 through the coordinated loading of the first loading plate 31, the second loading plate 32 and the third loading plate 33, and the resin can be arranged in sequence in the transverse direction. The moving strokes of the first loading plate 31 and the third loading plate 33 are both small to prevent the resin from falling during the movement.

[0075] The working principle of the chip plastic packaging equipment of the preferred embodiment of the utility model is as follows:

[0076] 1. When the first loading plate 31 moves from a position lower than the second loading plate 32 to a position higher than the second loading plate 32, the resin rolls from the first loading plate 31 to the second loading plate 32; when the third loading plate 33 slides from a position higher than the second loading plate 32 to a position lower than the second loading plate 32, the resin rolls from the second loading plate 32 to the third loading plate 33; when the third loading plate 33 moves from a position lower than the conveyor belt 121 to a position higher than the conveyor belt 121, the resin slides from the third loading plate 33 to the conveyor belt 121;

[0077] 2. The conveyor belt 121 moves the resin from the upper material position to the lower material position;

[0078] 3. When the resin with a horizontal axis passes through the longitudinal screening part 131, the avoidance surface 1312 avoids one side of the resin in the longitudinal direction so that it can smoothly pass through the longitudinal screening block 13; when the resin with a longitudinal axis passes through the longitudinal screening part 131, the guide surface 1311 guides the end of the resin so that it continues to move toward the direction close to the discharge position. When the resin moves to the end of the longitudinal screening part 131, the resin loses its center of gravity and falls from the side of the conveyor belt 121 away from the vertical plate 111;

[0079] 4. When the axial direction of the resin is horizontal, it can pass smoothly from the bottom of the vertical screening part 141 when passing through the vertical screening part 141; when the axial direction of the resin is vertical, it moves along the guide edge 1411 in the direction away from the vertical plate 111 when passing through the vertical screening part 141, and finally falls from the side of the conveyor belt 121 away from the vertical plate 111; when two resins with horizontal axes are stacked vertically, the resin located on the upper side moves along the guide edge 1411 in the direction away from the vertical plate 111, and finally falls from the side of the conveyor belt 121 away from the vertical plate 111, so that the resin located on the lower side can pass smoothly;

[0080] 5. When the axial direction of the resin is horizontal, when it passes through the tilt adjustment strip 1133, since the top of the tilt adjustment strip 1133 is tilted away from the vertical plate 111, the resin in this posture can be avoided and passed smoothly; when the resin is in an inclined state, since the end of the tilt adjustment strip 1133 facing the vertical screening plate 14 is tilted, its top is tilted in the direction close to the material discharge position, so that the resin in this posture can be guided to make its axial direction horizontal;

[0081] 6. When the resin falls from the conveyor belt 121, it first falls on the first step 211, then slides along the first step 211 toward the second side plate 22, falls on the second step 212, then slides along the second step 212 toward the third side plate 23, and finally falls on the bottom plate 24, and can be reloaded.

[0082] This completes the working principle of the chip packaging equipment of this preferred embodiment.

[0083] The resin posture screening device and chip encapsulation equipment of the utility model, after the resin is located at the upper material position, the conveyor belt moves the resin from the upper material position to the lower material position. When the resin with a horizontal axis passes through the longitudinal screening part, the avoidance surface avoids the longitudinal side of the resin so that it can smoothly pass through the longitudinal screening block. When the resin with a longitudinal axis passes through the longitudinal screening part, the guide surface guides the end of the resin so that it continues to move in the direction close to the lower material position. When the resin moves to the end of the longitudinal screening part, the resin loses its center of gravity and falls from the side of the conveyor belt away from the vertical plate. The resin posture screening device and chip encapsulation equipment of the utility model can push the resin with a longitudinal axis away from the conveyor belt through the longitudinal screening block, so that the resin with a transverse axis can pass smoothly, which is convenient for subsequent production and processing.
