Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging equipment technology, and in particular to a high-conductivity composite material packaging device. Background Technology

[0002] Semiconductor packaging refers to the process of processing tested wafers into individual chips according to product models and functional requirements. That is, the wafers from the front-end wafer process are cut into small chips through a dicing process. The cut chips are then glued onto the corresponding substrates. Metal wires or bonding pads of the chips are then connected to the corresponding pins of the substrates to form the required circuits. Finally, the individual chips are encapsulated with a plastic encapsulation shell.

[0003] In the current technology for packaging high-conductivity composite semiconductors, the transfer of semiconductor raw materials and components is mainly carried out by chucks. However, when using chucks to pick up raw materials and components, leakage is prone to occur. If leakage is not detected and dealt with in time, it will have a certain impact on subsequent processing. In addition, chucks are easily clogged by dust and other reasons during use, and the small suction nozzle structure of the chuck is not convenient to clean, which is not conducive to equipment maintenance.

[0004] Therefore, it is necessary to invent a high-conductivity composite material packaging device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-conductivity composite material packaging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-conductivity composite material packaging device, comprising a frame and a lifting platform mounted above the frame. Multiple material-picking rods are arranged around the bottom of the lifting platform. Each material-picking rod has a gas channel inside. An extension tube is fixedly attached to the bottom of the outer wall of each material-picking rod, with one end extending into the gas channel. A connecting tube is fixedly attached to the other end of the extension tube. A fixing cover is fixedly attached to the top of the connecting tube. A piston is slidably mounted inside the fixing cover, and a first spring is provided between the piston and the bottom of the fixing cover. A pressure rod is fixedly attached to the top of the piston. A conductive seat is fixedly attached to the lower surface of the piston. A conductive ring is provided inside the fixing cover, and a second spring is provided between the conductive ring and the bottom of the fixing cover. An alarm is provided on the outer side of the fixing cover, and the conductive ring and conductive seat are electrically connected to the alarm.

[0007] Preferably, the alarm includes a PLC controller, a buzzer, a power supply, and indicator lights.

[0008] Preferably, the bottom of the material-receiving rod has a slot, which is staggered with the gas channel, and one end of the slot extends to the outer surface of the material-receiving rod. A movable plug is inserted into the inside of the slot, and a venting groove is provided through the middle of the movable plug, which is adapted to the gas channel.

[0009] Preferably, a fixed sleeve is fixedly provided at the slot opening of the slot, one end of the movable plug is slidably disposed in the fixed sleeve, and a third spring is provided between the movable plug and the inner wall of the fixed sleeve. A strip groove is provided through the outer side of the fixed sleeve, and a sliding rod is fixedly provided at one end of the movable plug, and the sliding rod is slidably disposed in the strip groove.

[0010] Preferably, the bottom end of the material picking rod is fixedly provided with a suction nozzle sleeve, the outer side of the suction nozzle sleeve is detachably provided with a rubber suction nozzle, the outer wall of the suction nozzle sleeve is provided with a ring-shaped groove, and the inner top of the rubber suction nozzle is fixedly provided with a locking block that matches the groove.

[0011] Preferably, a feeding guide rail is fixedly provided on the upper surface of the frame, and a material tray is fixedly provided on the outer side of the frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model includes a material-collecting rod, a connecting pipe, a fixed cover, a piston, a conductive seat, a conductive ring, and an alarm. During the process of the material-collecting rod absorbing raw materials, the rubber suction nozzle at the bottom of the rod is blocked by the raw materials. The piston inside the fixed cover, which is connected to the gas channel inside the material-collecting rod, moves downward under negative pressure. The piston drives the conductive seat downward so that it contacts the conductive ring, completing the circuit connection. At this time, the alarm receives the circuit connection signal. When the raw materials are not absorbed and leakage occurs, no negative pressure is generated inside the gas channel, and the piston does not drive the conductive seat downward. In this case, the alarm cannot receive the circuit connection signal. At this time, the preset program inside the alarm controls the buzzer to sound an alarm to prompt the staff to intervene.

[0014] 2. This utility model, by setting a slot, a movable plug, and a venting groove, allows the venting groove inside the movable plug to open the gas channel inside the material picking rod. When the rubber suction nozzle at the bottom of the material picking rod is blocked, pressing the movable plug causes the venting groove inside to misalign with the gas channel, thus sealing the gas channel. At this time, pressing the pressure rod causes the piston to move downward, and the piston quickly forces the gas out of the fixed cover. The gas is then quickly ejected through the rubber suction nozzle to quickly clean the inside of the rubber suction nozzle, thereby solving the problem of the small suction nozzle being inconvenient to clean.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0022] This utility model provides, for example Figure 1-5 A high-conductivity composite material encapsulation device is shown, including a frame 1 and a lifting platform 2 mounted on the frame 1. Multiple picking rods 3 are arranged around the bottom of the lifting platform 2. Each picking rod 3 has a gas channel inside. An extension tube 4 is fixed to the bottom of the outer wall of the picking rod 3, with one end of the extension tube 4 extending into the gas channel and the other end of the extension tube 4 fixed to a connecting tube 5. A fixing cover 6 is fixed to the top of the connecting tube 5. A piston 7 is slidably arranged inside the fixing cover 6, and a first spring is provided between the piston 7 and the bottom of the fixing cover 6. A pressure rod 8 is fixed to the top of the piston 7, and a conductive seat 9 is fixed to the lower surface of the piston 7. A conductive ring 10 is provided inside the fixing cover 6, and a second spring is provided between the conductive ring 10 and the bottom of the fixing cover 6. The first spring provides a reset force for the piston 7, and the second spring provides travel space for the conductive ring 10. When the piston 7 is pressed to clean the device, the piston 7 can press down on the conductive ring 10 to move it downwards synchronously, thus avoiding interference between the conductive ring 10 and the movement of the piston 7.

[0023] An alarm is provided on the outer side of the fixed cover 6. The conductive ring 10 and the conductive base 9 are electrically connected to the alarm. The alarm includes a PLC controller, a buzzer, a power supply, and an indicator light. It should be noted that the PLC controller, buzzer, power supply, and indicator light are all commercially available models. The PLC controller has a program that can detect the circuit continuity between the conductive ring 10 and the conductive base 9 during the process of the lifting platform 2 driving the material picking rod 3 to move downward to pick up materials, and control the buzzer and indicator light to issue alarm information according to the circuit continuity.

[0024] The bottom of the material picking rod 3 is provided with a slot 11. The slot 11 is staggered with the gas channel, and one end of the slot 11 extends to the outer surface of the material picking rod 3. A movable plug 12 is inserted into the slot 11. A ventilation groove 13 is provided through the middle of the movable plug 12 and is adapted to the gas channel. A fixed sleeve 14 is fixed at the slot opening of the slot 11. One end of the movable plug 12 is slidably disposed in the fixed sleeve 14. A third spring is provided between the movable plug 12 and the inner wall of the fixed sleeve 14. A strip groove 15 is provided through the outer side of the fixed sleeve 14. A sliding rod 16 is fixed at one end of the movable plug 12 and is slidably disposed in the strip groove 15. The sliding rod 16 is used to facilitate the operator to pull the movable plug 12. The third spring is used to provide a reset force for the movable plug 12, so that the ventilation groove 13 in the middle of the movable plug 12 coincides with the gas channel.

[0025] The bottom end of the feeding rod 3 is fixedly provided with a suction nozzle sleeve 17. A rubber suction nozzle 18 is detachably provided on the outer side of the suction nozzle sleeve 17. A ring-shaped slot 19 is opened on the outer side wall of the suction nozzle sleeve 17. A locking block 20 that matches the slot 19 is fixedly provided on the inner top of the rubber suction nozzle 18. The locking block 20 cooperates with the slot 19 to fix the rubber suction nozzle 18 on the outer side of the suction nozzle sleeve 17.

[0026] The upper surface of the frame 1 is fixedly provided with a feeding guide rail 21, and the outer side of the frame 1 is fixedly provided with a material tray 22. The material tray 22 and the feeding guide rail 21 are used to feed raw materials and accessories. The model is the one that is available on the market.

[0027] Working principle of this utility model:

[0028] When this device is in use, the raw material component made of high conductivity composite material is guided by the material tray 22 and the feeding guide rail 21 to move to the top of the frame 1. The lifting platform 2 drives the picking rod 3 to rotate and move downward, so that the rubber suction nozzle 18 at the bottom of the picking rod 3 moves to the top of the raw material component at one end of the feeding guide rail 21. At this time, the air compressor draws air from the rubber suction nozzle 18 through the gas channel inside the picking rod 3, so that a negative pressure is formed between the rubber suction nozzle 18 and the raw material component. At this time, the raw material component is sucked up by the rubber suction nozzle 18. The raw material component then seals the bottom of the rubber suction nozzle 18. After the raw material component is sucked up, the lifting platform 2 drives the picking rod 3 to rotate, so as to realize the movement of the raw material component, thereby facilitating subsequent processing.

[0029] During the process of picking up raw material components, if the raw material components are normally picked up, they will block the bottom of the rubber suction nozzle 18, causing a negative pressure to form in the gas channel inside the picking rod 3. Correspondingly, a negative pressure is formed inside the fixed cover 6 connected to the gas channel. At this time, the piston 7 inside the fixed cover 6 moves downward under the action of negative pressure. The piston 7 drives the conductive seat 9 to move downward, so that the conductive seat 9 contacts the conductive ring 10 to complete the circuit conduction. The PLC controller in the alarm receives the electrical signal that the circuit between the conductive seat 9 and the conductive ring 10 is completed. At this time, its internal preset program will not control the buzzer to alarm, and the device is operating normally.

[0030] If material leakage occurs due to the material not being properly sucked up, the rubber suction nozzle 18 is not blocked by the material, and the internal gas channel of the material picking rod 3 does not form a negative pressure. At this time, the circuit between the conductive seat 9 and the conductive ring 10 is broken. The PLC controller in the alarm sends a command to the buzzer to make the buzzer sound an alarm, so as to prompt the staff to manually intervene. It should be noted that the PLC controller and the controller of the lifting platform 2 can be linked. When the lifting platform 2 moves the material picking rod 3 downward to pick up the material, the PLC controller will detect the continuity of the circuit between the conductive seat 9 and the conductive ring 10 to avoid false alarms when the device is not picking up material.

[0031] When the rubber nozzle 18 is clogged with dust, the sliding rod 16 at one end of the movable plug 12 is pulled to move it until the vent groove 13 in the middle of the movable plug 12 is misaligned with the gas channel. At this time, the movable plug 12 blocks the bottom part of the gas channel. Then, the pressure rod 8 is pressed to make the piston 7 move downward quickly. The piston 7 quickly forces the air in the fixed cover 6 into the gas channel. The gas in the gas channel blows out the dust that is clogged in the rubber nozzle 18, so as to achieve the effect of quickly cleaning the rubber nozzle 18.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
