Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figure 1 , Figure 2 and Figure 3This invention provides a rotary feeding mechanism, including a base plate 1, a machine arm 2, and a hydraulic cylinder 3. The machine arm 2 is fixed to one side of the upper surface of the base plate 1, and the hydraulic cylinder 3 is fixed to the upper end of the machine arm 2. It also includes a support rod 4, a turntable 5, a lower mold 6, an upper mold 7, a telescopic groove 8, a demolding rod 9, a rotary feeding mechanism 10, a demolding mechanism 11, and a discharging mechanism 12. The support rod 4 is rotatably connected to the middle of the upper surface of the base plate 1 away from the machine arm 2 via bearings. The turntable 5 is fixed to the top of the support rod 4. Four lower molds 6 are equidistantly embedded and fixed to the surface of the turntable 5, and the surface of each lower mold 6 has four mold cavities. The upper mold 7 is fixed to the extension of the hydraulic cylinder 3. At the end, the telescopic groove 8 is opened at the bottom of the inner wall of the mold cavity, and the telescopic groove 8 extends through the lower mold 6 to the bottom of the lower mold 6. The demolding rod 9 is slidably connected to the inner wall of the telescopic groove 8, and the upper surface of the demolding rod 9 is flush with the bottom of the inner wall of the mold cavity. The bottom of the four demolding rods 9 on the same lower mold 6 is fixed with connecting plates 9a. The rotary feeding mechanism 10 is fixed at the lower end of the outer wall of the supporting rotating rod 4, and is used to drive the turntable 5 to rotate when the hydraulic cylinder 3 extends. The demolding mechanism 11 is fixed at the bottom of the connecting plate 9a, and is used to push the product in the upper mold cavity of the lower mold 6 out of the inner cavity. The unloading mechanism 12 is fixed on one side of the top of the base plate 1, and is used to unload the demolded product.

[0021] It should be noted that the rotary feeding mechanism proposed in this application allows the chip encapsulation process, the unloading of the previous batch of encapsulated chips, and the feeding of the next batch of chips to be encapsulated to be carried out simultaneously. Compared with traditional chip encapsulation equipment, it is not necessary to perform loading and unloading again after the chip encapsulation is completed, thereby greatly improving the overall chip encapsulation efficiency and facilitating mass production.

[0022] Please see Figure 4 and Figure 5The rotary feeding mechanism 10 includes a Geneva wheel 101, a rotating shaft 102, a one-way bearing 103, a drive wheel 104, a reversing gear set 105, a moving plate 106, a rack 107, a drive plate 108, an L-shaped push bar 109, and a first drive column 1010. The Geneva wheel 101 is fixed to the lower end of the outer wall of the supporting rotating rod 4. The rotating shaft 102 is rotatably connected to the middle part of the upper surface of the base plate 1 near the Geneva wheel 101 via a bearing. The one-way bearing 103 is fixed to the lower end of the rotating shaft 102. The drive wheel 104 is fixed to the lower end of the rotating shaft 102 and cooperates with the Geneva wheel 101. The reversing gear set 105 is fixed to the outer ring of the one-way bearing 103. The moving plate 106 is slidably connected to the Geneva wheel 101. On the upper surface of the base plate 1 near the side of the arm 2, a rack 107 is fixed to the upper surface of the moving plate 106 near the side of the reverse gear set 105, and the rack 107 is meshed with the reverse gear set 105. Two drive plates 108 are symmetrically fixed on the top of the moving plate 106, and a first guide groove 108a is provided in the middle of the drive plate 108. An L-shaped push bar 109 is slidably connected to the outer wall of the arm 2 near the side of the hydraulic cylinder 3, and the upper end of the L-shaped push bar 109 is fixed to the extended end of the hydraulic cylinder 3. A first drive column 1010 is rotatably connected to the lower end of the L-shaped push bar 109 through a bearing, and the first drive column 1010 is rolledly connected to the inner wall of the first guide groove 108a.

[0023] Please see Figure 13 and Figure 14 The reversing gear set 105 includes a reversing sleeve 1051, a first gear 1052, a second gear 1053, a first bevel gear 1054, a second bevel gear 1055, and a third bevel gear 1056. The outer ring of the one-way bearing 103 is fixed with the reversing sleeve 1051. The lower end of the outer wall of the reversing sleeve 1051 is rotatably connected to the first gear 1052 via a bearing. The first gear 1052 meshes with a rack 107. The upper end of the outer wall of the reversing sleeve 1051 is fixed with the second gear 1053. A first bevel gear 1054 is fixed to the top of gear 1052. A second bevel gear 1055 is rotatably connected to the upper end of the outer wall of the flip sleeve 1051 through a shaft pin. A third bevel gear 1056 is fixed to the upper end of the inner wall of the second gear 1053. Both the third bevel gear 1056 and the first bevel gear 1054 are meshed with the second bevel gear 1055. Thus, when the rack 107 moves the first gear 1052, the second gear 1053 rotates in the opposite direction to the first gear 1052, thereby driving the rotating shaft 102 to rotate.

[0024] It should be noted that the outer walls of the grooved wheel 101 and the drive wheel 104 are in contact, and there is a certain friction between them. When the rack 107 rotates the reverse gear set 105 during the reset process, the one-way bearing 103 cannot drive the rotating shaft 102 to rotate. At the same time, due to the certain friction between the grooved wheel 101 and the drive wheel 104, the drive wheel 104 can remain stable. It should also be noted that during use, a robotic arm is installed on the side of the base plate 1 away from the robotic arm 2 to load the chips. When encapsulation is required, the hydraulic cylinder 3 extends, pushing the upper mold 7 downward. Simultaneously, the extension causes the L-shaped pusher bar 109 to slide downward, pushing the first drive column 1010 downward. Through the cooperation of the first drive column 1010 and the second guide rail groove 112, the drive plate 108 slides closer to the vertical plate 121, causing the moving plate 106 to slide. This, in turn, causes the rack 107 to move, rotating the reversing gear set 105. The rack 107, as it moves closer to the vertical plate 121... When one side of 1 slides, the reverse gear set 105 rotates and drives the rotating shaft 102 to rotate through the one-way bearing 103. The rotating shaft 102 then drives the wheel to rotate, thereby causing the grooved wheel 101 to rotate, which in turn drives the support rotating rod 4 to rotate, thereby driving the turntable 5 to rotate. Finally, the turntable 5 rotates 90 degrees. At this time, the upper mold 7 has not yet contacted the lower mold 6. Then the upper mold 7 continues to descend, and the turntable 5 stops rotating. Then the upper mold 7 is pressed onto the lower mold 6 for the molding operation. While the molding operation is being performed, the robot arm holds the chip and places it inside the cavity of the lower mold 6 on the side away from the robot arm 2 for the subsequent chip loading operation. After the encapsulation process is completed, the hydraulic cylinder 3 retracts, causing the upper mold 7 to move upward. After the upper mold 7 moves a certain distance, the L-shaped push bar 109 moves upward. Through the cooperation of the first drive column 1010 and the first guide rail groove 108a, the drive plate 108 can slide away from the column 111. At this time, the rack 107 resets and slides. However, the rack 107 drives the reverse gear set 105 to rotate. Due to the setting of the one-way bearing 103, it cannot drive the rotating shaft 102 to rotate, so the turntable 5 does not move. The above operation is repeated when the hydraulic cylinder 3 retracts to the position and moves downward again to carry out the encapsulation of the chip on the lower mold 6.

[0025] Please see Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9The demolding mechanism 11 includes a column 111, an annular plate 115, a second guide rail groove 112, a lifting column 113, and a second drive column 114. The three columns 111 are fixed at equal intervals on the upper surface of the base plate 1 away from the machine arm 2. The annular plate 115 is fixed to the upper end of the three columns 111. The second guide rail groove 112 is opened on the inner wall of the annular plate 115. A recessed groove 112a is formed on one side of the inner wall of the second guide rail groove 112, and a protruding groove 112b is formed on the side of the inner wall of the second guide rail groove 112 near the recessed groove 112a. The lifting column 113 is fixed to the bottom of the connecting plate 9a. The second drive column 114 is rotatably connected to the lower end of the lifting column 113 through a bearing, and the second drive column 114 is in rolling connection with the inner wall of the second guide rail groove 112.

[0026] It should be noted that when the turntable 5 rotates to perform the chip rotation work after the molding process, the rotation of the turntable 5 can drive the lifting column 113 to rotate synchronously. When the lifting column 113 rotates, the second drive column 114 rolls along the inner wall of the second guide rail groove 112. When the second drive column 114 reaches the recessed groove 112a inside the second guide rail groove 112, the lifting column 113 can slide downward, thereby pulling the demolding rod 9 downward. The downward sliding of the demolding rod 9 can separate the top of the demolding rod 9 from the outer wall of the molded chip, performing the initial demolding work. Then the lifting column 113 continues to rotate, and the second drive column 114 reaches the protruding groove 112b, thereby pushing the lifting column 113 upward, thereby pushing the demolding rod 9 upward to push the chip out from the inner wall of the mold cavity. When the lifting column 113 rises to its highest height, the top of the demolding rod 9 is flush with the top of the lower mold 6, that is, the bottom of the chip is flush with the top of the lower mold 6.

[0027] Please see Figure 7 The bottom of the turntable 5 is fixed with stabilizing sleeves 13 at equal intervals. The lifting column 113 is slidably connected to the inner wall of the stabilizing sleeve 13, which can improve the stability of the lifting column 113.

[0028] Please see Figure 6 A horizontal bar 14 is fixed to the side of the column 111 near the support rod 4. A support sleeve 15 is fixed to the side of the three horizontal bars 14 near the support rod 4. The support rod 4 is rotatably connected to the inner wall of the support sleeve 15 through a bearing, which can improve the stability of the support rod 4.

[0029] Please see Figure 10 and Figure 11The feeding mechanism 12 includes a vertical plate 121, a collection box 122, a feeding connecting strip 123, a feeding brush 124, and a feeding guide plate 125. The vertical plate 121 is fixed to one side of the upper surface of the base plate 1, the collection box 122 is fixed to the top of the vertical plate 121, the feeding connecting strip 123 is fixed to one side of the outer wall of the collection box 122, the feeding brush 124 is fixed to the upper end of the feeding connecting strip 123, the feeding brush 124 cooperates with the lower mold 6, and the feeding guide plate 125 is fixed to the outer wall of the lower mold 6, with one end of the feeding guide plate 125 located above the collection box 122.

[0030] It should be noted that after the turntable 5 rotates and the chip is ejected onto the top of the lower mold 6 by the ejector rod 9, the turntable 5 continues to rotate, driving the chip to the unloading brush 124. Under the action of the rotation of the turntable 5, the chip is brushed onto the unloading guide plate 125 by the unloading brush 124, and then enters the collection box 122 through the unloading guide plate 125, thus completing the chip unloading process. Then, as the turntable 5 continues to rotate, the empty lower mold 6 reaches the robot arm for loading again. After the chip is unloaded, as the turntable 5 continues to rotate, the ejector rod 9 can continue to move downwards to reset, that is, the top of the ejector rod 9 is flush with the inner wall of the mold cavity. Please see Figure 11 The feeding guide plate 125 is set at an angle, which makes it easy for the chip to slide into the inside of the collection box 122.

[0031] Please see Figure 5 A sliding sleeve 16 is fixed on the outer wall of the arm 2 near the L-shaped push bar 109. The L-shaped push bar 109 is slidably connected to the inner wall of the sliding sleeve 16, which facilitates the sliding of the L-shaped push bar 109.

[0032] Please see Figure 12 The present invention also provides a chip packaging device, including a screw extruder 17 and the aforementioned rotary feeding mechanism. The discharge end of the screw extruder 17 is slidably connected to a discharge pipe 18. One end of the discharge pipe 18 away from the screw extruder 17 is fixed to the surface of the lower mold 6, and the discharge end of the discharge pipe 18 is connected to the injection port of the lower mold 6. After the upper mold 7 and the lower mold 6 are pressed together, the plasticizing molten material is extruded into the space between the upper mold 7 and the lower mold 6 through the screw extruder 17 for plasticizing. When the hydraulic cylinder 3 extends, the discharge pipe 18 can be simultaneously driven to slide downward along the discharge end of the screw extruder 17. The discharge pipe 18 and the discharge end of the screw extruder 17 are slidably connected by a sliding sealing bearing, so that the two have good sealing performance.

[0033] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
