Description

Technical Field

[0001] This invention relates to the field of semiconductor packaging technology, and in particular to a cake transfer system. Background Technology

[0002] Molding is a crucial step in the semiconductor chip packaging process. Its main purpose is to encapsulate the chip, lead frame, and bonding wires using encapsulation materials such as resin to form a protective shell. During molding, the solid resin cake needs to be preheated and softened before being placed into a mold for subsequent injection molding.

[0003] In existing technologies, resin cakes are usually placed directly into a high-frequency preheating machine for preheating by manual labor. Since the preheated resin cakes become soft and cannot be grasped by mechanical structures, they can only be removed manually and placed into the mold. This is labor-intensive and inefficient. Furthermore, since the preheating and transfer of the resin cakes requires purely manual operation, it is impossible to achieve automated encapsulation of semiconductor chips. Summary of the Invention

[0004] Therefore, it is necessary to provide a resin cake transfer system to address the problems of the inability to automate resin cake transfer and the low efficiency of manual transfer.

[0005] A cake transfer system, comprising:

[0006] A preheating cylinder has a connected receiving groove and a discharge channel. The inner diameter of the receiving groove matches the outer diameter of the material cake. The temperature of the preheating cylinder in the preheating device is always lower than the heat deformation temperature of the preheating cylinder. Several material cakes are contained in the receiving groove, and the material cakes can be removed from the preheating cylinder through the discharge channel.

[0007] A placement mechanism, wherein multiple preheating cylinders are placed in the placement mechanism;

[0008] The transfer device is capable of clamping the preheating cylinder and transferring it to the preheating device or feeding station.

[0009] In one embodiment, the preheating cylinder includes:

[0010] The cylindrical body has the receiving groove and the discharge channel distributed sequentially along the axial direction of the cylindrical body;

[0011] A blocking element is disposed at one end of the cylinder opposite to the discharge channel. The blocking element is used to block the receiving groove to restrict the material cake from falling out of the cylinder.

[0012] In one embodiment, the inner diameter of the discharge channel gradually increases along the axial direction of the cylinder away from the receiving groove.

[0013] In one embodiment, the preheating device is a high-frequency preheater, and the preheating cylinder is made of Teflon.

[0014] In one embodiment, the preheating cylinder has several through holes on its outer periphery.

[0015] In one embodiment, the placement mechanism includes:

[0016] Frame;

[0017] Multiple placement seats are spaced apart on the frame. Each placement seat has a placement groove extending through it along a first direction. The preheating cylinder is placed in the placement groove, and the outer periphery of the preheating cylinder is attached to the placement groove.

[0018] In one embodiment, the placement mechanism further includes a plurality of limiting components, each of which corresponds to a plurality of placement seats. The limiting components have a limiting state and an avoidance state. When in the limiting state, at least a portion of the projection of the limiting components along the second direction overlaps with the placement groove. When in the avoidance state, the projection of the limiting components along the second direction avoids the placement groove. The second direction is perpendicular to the first direction.

[0019] In one embodiment, the limiting component includes:

[0020] A first driving member, the fixed end of which is connected to the frame, and the output end of the first driving member extends along the second direction;

[0021] A first limiting member is disposed at the output end of the first driving member. The first driving member can drive the first limiting member to rotate around the second direction to switch between a limiting state and an avoidance state. When in the limiting state, at least part of the projection of the first limiting member along the second direction overlaps with the placement groove. When in the avoidance state, the projection of the first limiting member in the second direction avoids the placement groove.

[0022] In one embodiment, the transfer device includes:

[0023] robotic arm;

[0024] A clamping mechanism is disposed at the end of the robotic arm. The clamping mechanism is configured to clamp or release the preheating cylinder. The robotic arm can drive the clamping mechanism to move to the placement mechanism, the preheating device, or the feeding station.

[0025] In one embodiment, the clamping mechanism includes:

[0026] Second drive unit;

[0027] The gripper assembly includes a first clamping plate and a second clamping plate spaced apart at the output end of the second drive member. The second drive member is capable of driving the first clamping plate and the second clamping plate to move closer or further apart to clamp or release the two ends of the preheating cylinder along its axial direction.

[0028] The aforementioned cake transfer system uses a preheating cylinder to carry the cake. Because the temperature of the preheating cylinder within the preheating device remains consistently below its heat distortion temperature, it does not soften during preheating and can be stably held by the clamping mechanism of the transfer device. This achieves automatic transfer of the preheating cylinder between the preheating device and the feeding station, eliminating the need for frequent manual handling of the soft cake and significantly reducing labor intensity. Throughout the transfer and preheating process, the cake remains within the preheating cylinder, ensuring stable positioning. This cake transfer system also provides the necessary conditions for automated molding and packaging of semiconductor chips; that is, by solving the problem of automated cake transfer, it makes automated molding and packaging of semiconductor chips possible.

[0045] like Figures 1-3 As shown, an embodiment of the present invention provides a cake transfer system, which includes a preheating cylinder 1, a placement mechanism 3, and a transfer device 4. The preheating cylinder 1 has a connected receiving groove 111 and a discharge channel 112. The inner diameter of the receiving groove 111 matches the outer diameter of the cake 2, and the temperature of the preheating cylinder 1 in the preheating device is always lower than the heat deformation temperature of the preheating cylinder 1. Several cakes 2 are placed in the receiving groove 111, and the cakes 2 can be removed from the preheating cylinder 1 through the discharge channel 112. Multiple preheating cylinders 1 are placed in the placement mechanism 3. The transfer device 4 can clamp the preheating cylinders 1 and transfer the preheating cylinders 1 to the preheating device or the feeding station.

[0046] Several material cakes 2 are placed in the receiving groove 111 of the preheating cylinder 1. Multiple preheating cylinders 1 containing material cakes 2 are placed on the placement mechanism 3. When it is necessary to soften the material cakes 2, the transfer device 4 clamps the preheating cylinder 1 and transfers the preheating cylinder 1 to the preheating device. In the preheating device, the material cakes 2 in the preheating cylinder 1 are preheated and softened. Since the temperature of the preheating cylinder 1 in the preheating device is always lower than the heat deformation temperature of the preheating cylinder 1, the preheating cylinder 1 will not soften during the preheating process and will always remain in a clampable state. After the preheating is completed, the transfer device 4 clamps the preheating cylinder 1 again and transfers the preheating cylinder 1 to the feeding station. At the feeding station, since the preheating cylinder 1 has a connected receiving groove 111 and a discharge channel 112, the softened material cakes 2 can be separated from the preheating cylinder 1 through the discharge channel 112 and put into the mold, preparing for the subsequent injection molding process.

[0047] This cake transfer system utilizes a preheating cylinder 1 to carry the cake 2. Since the temperature of the preheating cylinder 1 within the preheating device remains below its heat distortion temperature, it does not soften during preheating of the cake 2. Therefore, the preheating cylinder 1 can be stably held by the clamping mechanism 42 of the transfer device 4, achieving automatic transfer of the preheating cylinder 1 between the preheating device and the feeding station. Workers no longer need to frequently manually handle the soft cake 2, significantly reducing labor intensity. During transfer and preheating, the cake 2 remains within the preheating cylinder 1, ensuring its stable position. This cake transfer system also provides the necessary conditions for automated molding and encapsulation of semiconductor chips; that is, by solving the problem of automated transfer of the cake 2, it makes automated molding and encapsulation of semiconductor chips possible.

[0048] It should be noted that the material cake 2 can be loaded into the receiving trough 111 from the discharge channel 112 by an automated feeding device or manually. The specific feeding process will not be described in detail in this embodiment. The automated feeding device can refer to the structure commonly used in the prior art, and will not be described in detail in this embodiment.

[0049] It is worth mentioning that the inner diameter of the receiving groove 111 matches the outer diameter of the material cake 2, meaning that the inner diameter of the receiving groove 111 is sufficient to allow the material cake 2 to be loaded into and unloaded from the preheating cylinder 1. Generally, the inner diameter of the receiving groove 111 is slightly larger than that of the material cake 2. The specific dimensions of the inner diameter of the receiving groove 111 depend on the outer diameter of the material cake 2, and are not limited in this embodiment.

[0050] In this embodiment, the preheating device is a high-frequency preheater, and the preheating cylinder 1 is made of Teflon. The high-frequency preheater can generate a high-frequency electric field. When the cake 2 is placed in the high-frequency electric field, the molecules inside the cake 2 are polarized under the action of the electric field and arranged in the direction of the electric field. The direction of the high-frequency electric field changes rapidly, causing the molecules inside the cake 2 to oscillate at high speed and rub against each other, generating heat and softening the cake 2 during preheating. The Teflon material has a stable molecular structure and extremely low high-frequency dielectric loss, and hardly absorbs electromagnetic energy. At the same time, its high temperature resistance is much higher than the preheating temperature, so it will not soften or deform in the high-frequency preheater, ensuring that the transfer device 4 can stably clamp the preheating cylinder 1 for transfer.

[0051] Optionally, such as Figure 2 , Figure 3 As shown, the preheating cylinder 1 has several through holes 113 on its outer periphery. When the material cake 2 is preheated, it will release moisture, solvent or gas. The through holes 113 provide an overflow path for the moisture, solvent or gas, preventing the preheating cylinder 1 from deforming. In addition, the through holes 113 can reduce the amount of material used in the preheating cylinder 1, reduce production costs, and achieve lightweighting and easy transportation.

[0052] It should be noted that the preheating device can also be an infrared heating preheating device, which preheats the material cake 2 through infrared radiation, or a hot air circulation preheating device, a vacuum preheating device, or an electric heating plate preheating the material cake 2. Understandably, the preheating device can be any of the commonly used devices for heating the material cake 2 in the prior art, and the material selection of the preheating cylinder 1 must accordingly ensure that its temperature within the preheating device remains below the heat distortion temperature of the preheating cylinder 1.

[0053] Optionally, such as Figure 2 , Figure 3 As shown, the preheating cylinder 1 includes a cylinder body 11 and a blocking member 12. The cylinder body 11 has a receiving groove 111 and a discharge channel 112 arranged sequentially along the axial direction of the cylinder body 11. The blocking member 12 is located at the end of the cylinder body 11 opposite to the discharge channel 112. The blocking member 12 is used to block the receiving groove 111 to restrict the material cake 2 from falling out of the cylinder body 11. The receiving groove 111 and the discharge channel 112 are arranged sequentially along the axial direction of the cylinder body 11. The receiving groove 111 is used to receive the material cake 2 to be preheated. The discharge channel 112 is used for the directional discharge of the material cake 2 after preheating. The blocking member 12 is located at the end of the cylinder body 11 opposite to the discharge channel 112 to restrict the material cake 2 from falling out of the end of the cylinder body 11 opposite to the discharge channel 112, ensuring that the material cake 2 can only be discharged from the preheating cylinder 1 through the discharge channel 112, preventing the material cake 2 from accidentally falling out during the transfer process and causing resource waste.

[0054] In one optional embodiment, the cylinder 11 and the blocking member 12 are integrally formed; in another optional embodiment, the cylinder 11 and the blocking member 12 are separately formed, and the blocking member 12 is connected to the cylinder 11 by snap-fit, adhesive or fasteners such as screws and bolts.

[0055] Specifically, the shape of the blocking member 12 is the same as the cross-section of the cylinder 11, and the blocking member 12 has a through hole. The diameter of the through hole is smaller than the inner diameter of the receiving groove 111. When the blocking member 12 is set at one end of the preheating cylinder 1, the material cake 2 in the receiving groove 111 can be blocked by the blocking member 12, and the moisture, solvent or gas released by the material cake 2 during preheating can escape through the through hole.

[0056] Optionally, such as Figure 3 As shown, the inner diameter of the discharge channel 112 gradually increases in the direction away from the accommodating groove 111 along the axial direction of the cylinder 11. That is, along the discharge direction of the material cake 2, the inner diameter of the discharge channel 112 gradually expands, so that the material cake 2 can be discharged from the preheating cylinder 1 more smoothly.

[0057] Optionally, such as Figure 4As shown, the placement mechanism 3 includes a frame 31 and multiple placement seats 32. The multiple placement seats 32 are spaced apart on the frame 31. Each placement seat 32 has a placement groove 321 extending through it along a first direction. The preheating cylinder 1 is placed in the placement groove 321, and the outer periphery of the preheating cylinder 1 is in contact with the placement groove 321. The placement groove 321 extends through it along the first direction on the placement seat 32. The placement of the preheating cylinder 1 within it and its outer periphery in contact with the placement groove 321 ensures that the preheating cylinder 1 will not roll on the frame 31, thus ensuring good positional stability of the preheating cylinder 1. When the material cake 2 needs to be preheated, the transfer device 4 can easily clamp the preheating cylinder 1 and transfer it to the preheating device without the preheating cylinder 1 rolling, which would cause the clamping mechanism 42 to have difficulty clamping it.

[0058] In one alternative embodiment, such as Figure 4 As shown, a second limiting member 34 is provided at one end of the placement base 32 along the first direction. The second limiting member 34 is configured to limit the movement of the preheating cylinder 1 along the first direction to its extreme position. When the preheating cylinder 1 is placed on the placement base 32, the second limiting member 34 defines the extreme position of the preheating cylinder 1 on the placement base 32. When the preheating cylinder 1 abuts against the second limiting member 34, it is placed in place. The second limiting member 34 can also limit the preheating cylinder 1 from detaching along the first direction, preventing the preheating cylinder 1 from falling and causing resource waste.

[0059] Optionally, such as Figure 4 As shown, the placement mechanism 3 includes multiple limiting components 33, which correspond one-to-one with multiple placement seats 32. The limiting components 33 have a limiting state and an avoidance state. When in the limiting state, at least a portion of the projection of the limiting components 33 along the second direction overlaps with the placement groove 321. When in the avoidance state, the projection of the limiting components 33 along the second direction avoids the placement groove 321. The second direction is perpendicular to the first direction. When the preheating cylinder 1 is placed in the placement seat 32, the limiting component 33 is in a limiting state. At this time, at least part of the limiting component 33 is located above the preheating cylinder 1 along the second direction, which restricts the movement of the preheating cylinder 1 along the second direction. This ensures that the preheating cylinder 1 will not be displaced along the second direction and fall out of the placement seat 32 under the interference of external forces, so that the preheating cylinder 1 can be stably placed in the placement seat 32. When it is necessary to transfer the preheating cylinder 1, the limiting component 33 switches to the avoidance state. At this time, the projection of the limiting component 33 along the second direction avoids the placement groove 321, that is, it does not overlap with the placement groove 321. The transfer device 4 can directly clamp the preheating cylinder 1 and transfer it without interfering with the limiting component 33.

[0060] In one alternative embodiment, such as Figure 4As shown, the limiting component 33 includes a first driving member 331 and a first limiting member 332. The fixed end of the first driving member 331 is connected to the frame 31, and the output end of the first driving member 331 extends along the second direction. The first limiting member 332 is disposed at the output end of the first driving member 331. The first driving member 331 can drive the first limiting member 332 to rotate around the second direction to switch between a limiting state and an avoidance state. When in the limiting state, at least part of the projection of the first limiting member 332 along the second direction overlaps with the placement groove 321. When in the avoidance state, the projection of the first limiting member 332 in the second direction avoids the placement groove 321.

[0061] When the preheating cylinder 1 needs to be limited, the output end of the first driving member 331 rotates to drive the first limiting member 332 to rotate around the second direction, so that the first limiting member 332 rotates until at least part of its projection along the second direction overlaps with the placement groove 321; when the preheating cylinder 1 needs to be transferred, the output end of the first driving member 331 rotates to drive the first limiting member 332 to rotate around the second direction, so that the first limiting member 332 rotates until its projection along the second direction avoids the placement groove 321, that is, it does not overlap with the placement groove 321. By driving the first limiting member 332 to rotate around the second direction, the limiting component 33 can be switched between the limiting state and the avoidance state, which is simple and quick to operate.

[0062] It should be noted that the limiting component 33 can also be detachably connected to the frame 31. When it is necessary to switch to the limiting state, the limiting component 33 is installed on the frame 31 so that at least part of the projection of the limiting component 33 along the second direction overlaps with the placement slot 321. When it is necessary to switch to the avoidance state, the limiting component 33 is removed so that the projection of the limiting component 33 along the second direction avoids the placement slot 321.

[0063] Optionally, such as Figure 1As shown, the transfer device 4 includes a robotic arm 41 and a clamping mechanism 42. The clamping mechanism 42 is located at the end of the robotic arm 41 and is configured to clamp or release the preheating cylinder 1. The robotic arm 41 can drive the clamping mechanism 42 to the placement mechanism 3, the preheating device, or the feeding station. When the preheating cylinder 1 needs to be transferred to the preheating device for preheating, the robotic arm 41 drives the clamping mechanism 42 to the placement mechanism 3 according to a preset path and motion parameters, so that the clamping mechanism 42 can clamp the preheating cylinder 1. Then, the robotic arm 41 continues to drive the clamping mechanism 42 holding the preheating cylinder 1 to the preheating device, and accurately places the preheating cylinder 1 on the preheating device. The clamping mechanism 42 then releases the preheating cylinder 1, completing the transfer. When the preheated preheating cylinder 1 needs to be transferred to the feeding station, ... The robotic arm 41 moves the clamping mechanism 42 back to the preheating device, allowing the clamping mechanism 42 to hold the preheating cylinder 1. Then, the robotic arm 41 continues to move the clamping mechanism 42 holding the preheating cylinder 1 to the feeding station. The robotic arm 41 then moves the clamping mechanism 42 to change the position of the preheating cylinder 1, so that the discharge channel 112 of the preheating cylinder 1 faces the feeding station. At this time, the material cake 2 inside the preheating cylinder 1 will fall from the discharge channel 112 under the action of gravity, completing the feeding. Through the cooperation of the robotic arm 41 and the clamping mechanism 42, the preheating cylinder 1 can be quickly and accurately transferred from the placement mechanism 3 to the preheating device, and then from the preheating device to the feeding station. Compared with manual transfer, the transfer efficiency is higher, and labor costs are saved.

[0064] It should be noted that the robotic arm 41 can be either a joint coordinate system robotic arm 41 or a Cartesian coordinate system robotic arm 41, and the selection can be made according to the actual work requirements. This embodiment does not impose any limitations. Furthermore, the specific structure and working principle of the robotic arm 41 refer to the existing technology, and will not be described in detail in this embodiment.

[0065] Optionally, such as Figure 5 As shown, the clamping mechanism 42 includes a second driving member 421 and a gripper assembly 422. The gripper assembly 422 includes a first clamping plate 4221 and a second clamping plate 4222 spaced apart at the output end of the second driving member 421. The second driving member 421 can drive the first clamping plate 4221 and the second clamping plate 4222 to move closer or further apart to clamp or release the two ends of the preheating cylinder 1 along its axial direction. When it is necessary to clamp the preheating cylinder 1, the robotic arm 41 drives the clamping mechanism 42 to move to the placement mechanism 3, so that the first clamping plate 4221 and the second clamping plate 4222 are located at the two ends of the preheating cylinder 1 along its axial direction. Then, the second driving member 421 drives the first clamping plate 4221 and the second clamping plate 4222 to move closer together to clamp the two ends of the preheating cylinder 1 along its axial direction. At this time, the preheating cylinder 1 can be stably clamped. When it is necessary to release the preheating cylinder 1, the second driving member 421 drives the first clamping plate 4221 and the second clamping plate 4222 to move further apart to release the preheating cylinder 1.

[0066] Specifically, the second drive component 421 is a gripper cylinder.

[0067] It should be noted that, as Figure 5 As shown, the first clamping plate 4221 abuts against one end of the preheating cylinder 1 that has a discharge channel 112. The first clamping plate 4221 has a clearance opening that is connected to the discharge channel 112. When the material cake 2 falls under the action of gravity, it will not interfere with the first clamping plate 4221, that is, the first clamping plate 4221 will not affect the feeding process of the material cake 2.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
