Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0019] In the present application, the terms "first", "second", and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance, and are not limited as the order.
[0020] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.
[0021] The chip plastic sealing device is used for plastic sealing of a substrate provided with a chip. The chip plastic sealing device comprises a feeding device, a transferring device, a manipulator and a plastic sealing device. The feeding device is used for providing resin and the substrate, and can arrange a plurality of substrates and a plurality of resins into a raw material array; the transferring device is used for receiving and releasing the resin and the substrate, and the manipulator is connected to the transferring device and used for driving the transferring device to reciprocate between the feeding device and the plastic sealing device. When the transferring device is located at the feeding device, the transferring device can receive the resin and the substrate on the feeding device and limit the resin and the substrate on the transferring device; when the transferring device moves to the plastic sealing device, the transferring device releases the resin and the substrate, so that the resin and the substrate enter the plastic sealing device. The plastic sealing device heats the resin to melt and flow into the chip position of the substrate, so as to plastic seal the chip.
[0022] The feeding device can comprise a feeding sleeve, a top rod, a feeding driving element and a base, the base is used for placing the substrate, the feeding sleeve is used for placing the resin, the top rod is coaxially arranged with the feeding sleeve, the feeding driving element is connected to the top rod and used for driving the top rod to move vertically and for ejecting the resin in the feeding sleeve. The feeding sleeve and the top rod can be multiple, and multiple resins can be placed at the same time.
[0023] As shown in Figure 1 , the transferring device 100 can be multiple, and four in the embodiment. The multiple transferring devices 100 can be connected to the manipulator at the same time to improve the transferring efficiency.
[0024] In the embodiment, the feeding device and the rotating device can simultaneously feed the resin and the substrate to improve the processing efficiency. In other embodiments, only the resin can be fed, and the resin and the substrate can be fed respectively.
[0025] As shown in Figure 2 , Figure 3 , the transferring device 100 comprises a bracket 1, a barrel 2, a blocking piece 3, a detection assembly 4 and a clamping jaw mechanism 5. The barrel 2 and the blocking piece 3 are arranged on the bracket 1, the resin can be received in the barrel 2 and limited in the barrel 2 by the blocking piece 3; the clamping jaw mechanism 5 is arranged on the bracket 1 and used for clamping the substrate. The detection assembly 4 judges whether the resin is accurately received by detecting the position of the barrel 2. The manipulator can be connected to the bracket 1 to drive the bracket 1 to move, so that the whole transferring device 100 can reciprocate between the feeding device and the plastic sealing device.
[0026] The axial direction of the barrel 2 is vertical, and the barrel 2 is movably arranged in the bracket 1 along the vertical direction. The barrel 2 comprises a receiving and releasing position (as shown in Figure 4 ) and a transferring position (as shown in Figure 5As shown), the transfer position is higher than the receiving position. The bottom of the barrel 2 is open to allow resin to enter and exit the barrel 2. The resin can enter the barrel 2 through the bottom end. A limiting member 21 is provided at the top of the barrel 2. The limiting member 21 is used to abut the top of the resin. When the resin moves upward, the top of the resin can abut against the limiting member 21, and the limiting member 21 drives the barrel 2 to move upward together.
[0027] The stop member 3 is movably mounted on the bracket 1 to support or release the resin. The stop member 3 can limit the resin in the feed cylinder 2 for transfer.
[0028] Multiple material cylinders 2 can be mounted on a support 1 so that multiple resins can be transported simultaneously using a transfer device 100. In this embodiment, the multiple material cylinders 2 on the same support 1 are arranged laterally.
[0029] like Figure 4 As shown, when the material cylinder 2 is in the receiving / releasing position, the stop member 3 is in the releasing position to not obstruct the movement of resin within the material cylinder 2. After the transfer device 100 moves above the feeding device, the material cylinder 2 and the feeding sleeve are vertically aligned. The feeding drive member drives the push rod to move upward, and the push rod moves the resin upward, causing the resin to move from the feeding sleeve into the material cylinder 2. When the resin moves upward and abuts against the limiting member 21, it can drive the material cylinder 2 to move upward to the transfer position.
[0030] The resin cylinder 2 receives the resin at a lower receiving position, allowing it to be closer to the resin and ensuring more accurate entry. When the resin cylinder 2 is aligned with the feeding sleeve, a preset gap is maintained between them. This preset gap is smaller than the vertical dimension of the resin, facilitating smooth resin transfer between the feeding sleeve and the resin cylinder 2 and preventing damage caused by collisions. Simultaneously, the resin cylinder 2 provides better guidance for the upward movement of the resin, ensuring the stability and reliability of its upward movement.
[0031] like Figure 5 As shown, when the barrel 2, along with the resin 9, moves to the transfer position, the stop 3 moves to the support position and supports the resin 9 below, thus restricting the barrel 2 at the transfer position. Since the top of the resin 9 abuts against the limiting member 21, it provides support to both the limiting member 21 and the barrel 2, allowing the barrel 2 to be restricted at the transfer position while simultaneously confining the resin 9 within the barrel 2. The stop 3 can simultaneously limit both the barrel 2 and the resin 9, resulting in a simple structure, ingenious design, and ease of processing. Because the barrel 2 moves under the influence of the resin 9, if the barrel 2 does not move to the correct position, it indicates that the resin 9 has not been accurately received or is incomplete, preventing the barrel 2 from moving to the transfer position. Therefore, the detection component 4 can detect whether the resin 9 has been accurately received by monitoring the position of the barrel 2.
[0032] At this time, the transfer device 100 carrying the resin 9 and the substrate can be moved to the plastic packaging device by the mechanical arm. The support 1 can be provided with a gripper mechanism 5. While the resin 9 is received by the barrel 2, the substrate is grabbed by the gripper mechanism 5, so that the transfer device 100 can simultaneously receive the resin 9 and the substrate.
[0033] After the transfer device 100 moves to the plastic packaging device, the resin 9 and the substrate can be released. When the blocking piece 3 moves to the release position, the blocking piece 3 cancels the support of the resin 9, thereby releasing the resin 9. The resin 9 is sent out from the bottom opening of the barrel 2 under the action of gravity, and the resin 9 falls into the receiving position of the plastic packaging device, and at the same time the barrel 2 moves to the storage position under the action of gravity, so as to perform the next operation.
[0034] After the transfer device 100 finishes discharging the resin 9 and the substrate, it is moved out of the plastic packaging device under the action of the mechanical arm. The plastic packaging device heats the resin 9 to melt and flow into the chip position of the substrate, thereby plastic packaging the chip.
[0035] When the transfer device 100 moves out of the plastic packaging device, the barrel 2 is in the storage position. When the transfer device 100 moves to the feeding device again, the resin 9 can be directly transferred. The vertical movement of the barrel 2 does not require driving force, the structure is simple, and the reliability and stability of the resin 9 conveying can be ensured.
[0036] The detection assembly 4 is used to detect the position state of the barrel 2, to confirm whether the resin 9 is accurately received, and also to detect whether the resin 9 is accurately released. Since the barrel 2 is vertically moved by the resin 9 in the embodiment, the position state of the barrel 2 is detected by the detection assembly 4, so that whether the resin 9 is accurately received can be detected, and the operation reliability is ensured.
[0037] The detection assembly 4 includes a first pair of photoelectric sensors 41 and a second pair of photoelectric sensors 42. The first pair of photoelectric sensors 41 and the second pair of photoelectric sensors 42 are arranged in the vertical direction and are arranged on the support 1.
[0038] The barrel wall of the barrel 2 is provided with a first detection hole 201 and a second detection hole 202. The first detection hole 201 is used to cooperate with the first pair of photoelectric sensors 41 to detect the barrel 2 in the storage position, and the second detection hole 202 is used to cooperate with the second pair of photoelectric sensors 42 to detect the barrel 2 in the transfer position. In the embodiment, the first detection hole 201 is located above the second detection hole 202, and correspondingly, the first pair of photoelectric sensors 41 is located above the second pair of photoelectric sensors 42, so that the distance between the first pair of photoelectric sensors 41 and the second pair of photoelectric sensors 42 is relatively short, facilitating assembly, and only a short distance of vertical movement of the barrel is required to realize detection, ensuring the stability and reliability of the movement of the barrel itself.
[0039] The arrangement direction of the plurality of cartridges 2 is the same as the light beam alignment direction of the first pair of light detectors 41 and the second pair of light detectors 42, so that the alignment light beam of the first pair of light detectors 41 can pass through the first detection holes 201 of the plurality of cartridges 2 at the same time, and the alignment light beam of the second pair of light detectors 42 can pass through the second detection holes 202 of the plurality of cartridges 2 at the same time. By using a set of detection assemblies 4, the state of the plurality of cartridges 2 can be detected at the same time, and an abnormality can be detected as long as one of them is abnormal, thereby reducing the cost of the equipment. In the embodiment, the two transfer devices 100 arranged in the transverse direction use the same set of detection assemblies 4 for detection, that is, eight cartridges 2 can be detected at the same time, and an abnormality can be detected as long as one of them is abnormal, thereby reducing the cost of the equipment.
[0040] As shown in Figure 4 When the cartridge 2 is located at the receiving and releasing position, the first detection hole 201 and the first pair of light detectors 41 are at the same height position for the alignment light beam 410 of the first pair of light detectors 41 to pass through, and the cartridge wall can block the alignment light beam 420 of the second pair of light detectors 42.
[0041] When the cartridge 2 normally falls to the receiving and releasing position, the alignment light beam 410 of the first pair of light detectors 41 passes through the first detection holes 201 of the plurality of cartridges 2 at the same time, and the first pair of light detectors 41 can detect that the light path is on. If one of the cartridges 2 does not fall to the receiving and releasing position, the cartridge wall will block the alignment light beam of the first pair of light detectors 41, so that the first pair of light detectors 41 detects an abnormal state.
[0042] As shown in Figure 5 When the cartridge 2 is located at the transfer position, the second detection hole 202 and the second pair of light detectors 42 are at the same height position for the alignment light beam 420 of the second pair of light detectors 42 to pass through, and the cartridge wall can block the alignment light beam 410 of the first pair of light detectors 41.
[0043] When the cartridge 2 receives the resin 9 and moves upward to the transfer position under the action of the resin 9, the second detection hole 202 moves upward to the same height position as the second pair of light detectors 42, and the alignment light beam 420 of the second pair of light detectors 42 can pass through the second detection holes 202 of the plurality of cartridges 2, so that the detection light path is on, which indicates that the cartridge 2 and the resin 9 are moved to the position, and the equipment is running normally. At this time, the blocking member 3 can move to the inner cavity of the cartridge 2 and support the resin 9 and the cartridge 2.
[0044] If the resin 9 is normally placed on the feeding device, the barrel 2 can normally receive the resin 9, and the barrel 2 can be moved to the transfer position under the driving of the resin 9. If the resin 9 is absent from the individual position on the feeding device, the barrel 2 has no resin 9 and cannot be moved upward under the driving of the resin 9. The corresponding barrel 2 at the position blocks the light beam of the second pair of light beams detector 42, and the second pair of light beams detector 42 can detect the disconnection of the light path, indicating that the equipment is running abnormally, and an alarm is given.
[0045] If the resin 9 is placed on the feeding device but has defects, for example, is half, the barrel 2 cannot be moved to the position, and the second pair of light beams detector 42 detects the disconnection of the light path. Thus, the second detector can detect whether the transfer device 100 correctly receives the qualified resin 9.
[0046] In the embodiment, as shown in Figure 5 , when the top end of the resin 9 abuts against the limiting piece 21, the bottom end of the resin 9 is lower than the first detection hole 201 and higher than the second detection hole 202. When the resin 9 is released, if the barrel 2 is lowered to the position, i.e., is located in the receiving and releasing position, the resin 9 is stuck in the barrel 2 and is not released, the resin 9 blocks the light beam of the first pair of light beams detector 41, the first pair of light beams detector 41 detects the disconnection of the light path, indicating that the resin 9 is released abnormally, and an alarm is given to prompt the staff to handle.
[0047] The first detection hole 201 and the second detection hole 202 are located in the lower half of the barrel 2. When the resin 9 is released, if the resin 9 does not block the first detection hole 201, it indicates that the top of the resin 9 has been moved below the first detection hole 201, most of the resin 9 has been located outside the bottom of the barrel 2, and it is impossible to be stuck in the barrel 2, thereby ensuring the detection reliability.
[0048] As shown in Figure 5 and Figure 6 , the limiting piece 21 is a reverse U-shaped clamp spring, and the two ends thereof are respectively clamped to the inner wall of the top of the barrel 2. The reverse U-shaped clamp spring can facilitate the assembly connection between the limiting piece 21 and the barrel 2. When the barrel 2 is running abnormally, the staff can hold the limiting piece 21 to check the barrel 2, or can remove the limiting piece 21 to take out the resin 9 in the barrel 2 or load the resin 9 from the top, thereby facilitating the fault handling.
[0049] As shown in Figure 5 , the bracket 1 is a plate-shaped structure, which is simple in structure and is convenient for processing and preparation. The bracket 1 is provided with a mounting hole 12, and the barrel 2 is vertically movably arranged in the mounting hole 12, thereby facilitating the assembly connection between the barrel 2 and the bracket 1. As shown in Figure 6 , Figure 7As shown, the top edge of the barrel 2 is provided with a flange, which can abut against the top of the support 1 to prevent the barrel 2 from being pulled out of the mounting hole, thereby limiting the lowest position of the barrel 2 relative to the support 1 and ensuring that it is located at the material collecting position.
[0050] The bottom inner wall of the barrel 2 is trumpet-shaped to facilitate the resin 9 to enter the barrel 2 more smoothly from the bottom of the barrel 2.
[0051] As shown in Figure 5 , Figure 8 The stop piece 3 is plate-shaped and horizontally arranged with the support 1. In this embodiment, the stop piece 3 is located below the support 1. The stop piece 3 is movably arranged horizontally. More specifically, the stop piece 3 moves horizontally, i.e. the moving direction is parallel to the arrangement direction of the plurality of barrels 2.
[0052] The stop piece 3 is provided with a stop tongue 31 for supporting the resin 9, and the barrel wall of the barrel 2 is provided with an insertion hole 203 corresponding to the stop tongue 31, so that the stop tongue 31 can enter and exit the inner cavity of the barrel 2. When the stop piece 3 is located at the supporting position, the stop tongue 31 extends into the inner cavity of the barrel 2, thereby supporting the resin 9. When the stop piece 3 is located at the releasing position, the stop tongue 31 moves out of the inner cavity of the barrel 2.
[0053] The insertion hole 203 is vertically arranged and is long strip-shaped, and the stop tongue 31 is located at the insertion hole 203. When the barrel 2 moves vertically, the stop tongue 31 can move in the insertion hole 203, thereby not hindering the movement of the barrel 2 and allowing the stop tongue 31 to be closer to the inner cavity of the barrel 2 when not supporting the resin 9, thereby reducing the displacement of the stop piece 3.
[0054] The support 1 is provided with a driving mechanism 32 connected to the stop piece 3, which is used to drive the stop piece 3 to move linearly between the releasing position and the supporting position, so that the stop tongue 31 enters and exits the inner cavity of the barrel 2 through the insertion hole 203.
[0055] In the embodiment, the driving mechanism 32 comprises a cylinder 321, a poking member 322, a driving frame 323 and an elastic member 324. The driving frame 323 is fixed to the top of the support 1. The poking member 322 is L-shaped, and the bending position of the poking member 322 is rotationally connected with the driving frame 323. One arm of the poking member 322 is arranged in the driving hole 30 of the gear member 3, and the other arm of the poking member 322 is connected with the elastic member 324. The cylinder 321 is arranged vertically on the support 1, and the piston rod of the cylinder 321 is used for abutting against the other arm of the poking member 322, so as to drive the poking member 322 to rotate forward, and then the one arm of the poking member 322 drives the gear member 3 to move, so that the gear tongue 31 is moved out of the inner cavity of the barrel 2. The elastic member 324 can provide reverse rotating force to the poking member 322, so as to move the gear tongue 31 into the inner cavity of the barrel 2. Under the action of the cylinder 321, the elastic member 324 can keep the gear tongue 31 in the inner cavity of the barrel 2, so as to avoid the resin 9 from falling due to accidental power-off. Herein, in other embodiments, the linear driving mechanism 32 can also directly adopt the cylinder 321. The cylinder 321 is arranged horizontally, and the piston rod of the cylinder 321 is connected with the gear member 3. Alternatively, the linear driving mechanism 32 is the cooperation of a motor and a ball screw, or other linear driving mechanisms 32.
[0056] The application further provides a resin feeding method using the transfer device 100.
[0057] In step S100, the transfer device 100 is moved to the position of the resin 9. At this time, the barrel 2 is located at the receiving position, and the gear member 3 is located at the releasing position, so as to receive the resin 9 fed by the feeding device.
[0058] More specifically, in this step, the resin 9 is placed in the feeding sleeve of the feeding device, and the transfer device 100 is moved above the feeding device. The barrel 2 is vertically aligned with the feeding sleeve. The barrel 2 abuts against the feeding sleeve or keeps a preset gap with the feeding sleeve. The preset gap is smaller than the vertical size of the resin 9, so as to facilitate the smooth transfer of the resin 9 between the feeding sleeve and the barrel 2.
[0059] In the embodiment, the mechanical hand is used to move the transfer device 100.
[0060] In step S200, the resin 9 is lifted upward, so as to enter the barrel 2. The top of the resin 9 abuts against the limiting member 21, and the barrel 2 is lifted upward to the transfer position.
[0061] In this step, the feeding driving member is used to lift the ejector rod, so as to eject the resin 9 from the feeding sleeve into the barrel 2, until the barrel 2 is lifted to the transfer position.
[0062] In step S300, the detection device is used to detect whether the barrel is at the transfer position. If the barrel 2 is at the transfer position, the next step is performed.
[0063] Specifically, the second through-beam detector 42 detects whether the material cylinder 2 is in the transfer position, such as... Figure 6 As shown, if the optical path of the second through-beam detector 42 is open, the material cylinder 2 is in the transfer position, and the next step continues. If the optical path of the second through-beam detector 42 is closed, an alarm is triggered, and operation is interrupted. When the optical path of the second through-beam detector 42 is closed, the feed drive can be used to move the push rod downwards, allowing the operator to remove the limiting piece 21, load resin 9 from the top of the material cylinder 2, reinstall the limiting piece 21, and restart the equipment, causing the push rod to move the resin 9 upwards again, thus lifting the material cylinder 2 into position.
[0064] Step S400, as follows Figure 6 As shown, the stop member 3 is moved to the support position so that it extends into the inner cavity of the barrel 2 and is supported below the resin 9, thereby confining the barrel 2 and the resin 9 at the transfer position. Subsequently, the feeding drive member drives the push rod to move down, and the feeding device can place the next batch of resin 9.
[0065] In step S500, the transfer device 100 is moved to a preset position. The preset position is the designated location where the resin 9 needs to be delivered. In this embodiment, since the resin 9 needs to be melted, the preset position is the sealing device.
[0066] In step S600, the stop component 3 is moved to the release position so that it exits from the inner cavity of the barrel 2. The resin 9 and barrel 2 move downwards simultaneously under gravity, and the resin 9 exits from the bottom opening of the barrel 2 and falls into a preset position, thus entering the molding equipment. Since the barrel 2 falls along with the resin 9, it continues to guide the resin 9 during its descent. This downward movement of the barrel 2 increases the guiding distance for the resin 9, ensuring a stable fall and preventing skewing.
[0067] In step S700, the detection device checks whether the material cylinder is in the take-up / delivery position. If the material cylinder 2 is in the take-up / delivery position, proceed to the next step.
[0068] The first through-beam detector 41 detects whether the material cylinder 2 has fallen to the take-up / delivery position. If the optical path of the first through-beam detector 41 is open, the material cylinder 2 is in the take-up / delivery position, and the next step continues. If the optical path of the first through-beam detector 41 is closed, an alarm is triggered, and the operation is interrupted.
[0069] In this step, the first through-beam detector 41 can be used to detect whether the resin 9 has been ejected from the barrel 2. If the optical path of the first through-beam detector 41 is open, the resin 9 has been ejected, and the next step is performed, that is, steps S100 to S700 are repeated. If the optical path of the first through-beam detector 41 is closed, an alarm is triggered, and the operation is interrupted.
[0070] To sum up, although the present application has been disclosed with preferred embodiments as above, the preferred embodiments are not used to limit the present application, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and therefore the protection scope of the present application is defined by the scope of the claims.
