Description

Technical Field

[0001] This utility model relates to the field of product processing production line technology, and in particular to a powder handling mechanism and a powder compression and packaging molding equipment. Background Technology

[0002] In the process of processing semiconductor chips using powder compression packaging equipment, the process involves packaging resin powder. During this process, the resin powder needs to be fed into the press by a resin handling mechanism for subsequent packaging and shaping. In the existing technology, the resin powder is usually stored in a powder feeding hopper. A certain amount of resin powder is evenly spread on the surface of a pre-set carrier film (such as thermoplastic film) by a vibrating feeder or a screw conveyor. Traditional resin handling mechanisms often use mechanical grippers to hold the edge of the film carrying the resin powder and transfer the entire film along with the resin powder on it from the powder spreading station to the press mold cavity. During the powder spreading and handling process, the resin powder may be unevenly distributed and fall off due to uneven film wrinkles and vibrations during handling, thereby reducing the yield of packaged products.

[0013] The embodiments of this utility model can achieve at least the following beneficial effects: In the powder handling mechanism provided in this embodiment of the present invention, when in use, the film is covered on the upper surface of the lower suction film plate, and the gas channel inside the lower suction film plate is evacuated by a vacuuming device. The film is firmly adsorbed onto the upper surface of the lower suction film plate through the air extraction holes and maintains a certain flatness.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] First aspect This embodiment provides a powder handling mechanism, referring to... Figures 1 to 3The powder handling mechanism includes a film suction assembly 100 and a handling assembly 200. Specifically, the film suction assembly 100 includes a lower film suction plate 110 and an upper film suction plate 120. Both the lower film suction plate 110 and the upper film suction plate 120 extend horizontally. A hollow area 1201 for powder application is provided in the middle of the upper film suction plate 120. Gas channels penetrating the respective plates are provided inside the lower film suction plate 110 and the upper film suction plate 120. Multiple air extraction holes 130 communicating with the gas channels inside the respective plates are provided on the upper surface of the lower film suction plate 110 and the lower surface of the upper film suction plate 120. The handling assembly 200 includes a robotic arm, a mounting frame 1, a plate clamping mechanism 2, and a membrane clamping mechanism 3. The mounting frame 1 is fixed to the end effector of the robotic arm, and an exhaust pipe 4 is provided on the robotic arm or the mounting frame 1 for sealing and docking with the gas channel provided on the upper membrane suction plate 120. The plate clamping mechanism 2 and the membrane clamping mechanism 3 are both mounted on the mounting frame 1. The plate clamping mechanism 2 is used to clamp or release the upper membrane suction plate 120, and the membrane clamping mechanism 3 is used to cooperate with the upper membrane suction plate 120 to clamp or release the membrane 300 adsorbed by the upper membrane suction plate 120.

[0028] The usage of this embodiment is as follows: In use, the film 300 is placed over the upper surface of the lower suction plate 110. The gas channels inside the lower suction plate 110 are evacuated using a vacuuming device. The film 300 is then firmly adsorbed onto the upper surface of the lower suction plate 110 through the air extraction holes 130 and maintains a certain degree of flatness. Then, the upper suction plate 120 is placed over the upper surface of the film 300, and powder (which can be resin powder or other material powder that needs to be transported) is evenly sprinkled onto the upper surface of the film 300 through the hollow area 1201 of the upper suction plate 120. Then, the robotic arm is controlled to move the mounting frame 1 above the upper suction film plate 120, so that the interface of the air extraction pipe 4 and the gas channel provided on the upper suction film plate 120 are sealed and connected; the vacuum adsorption of the film 300 by the lower suction film plate 110 is stopped, and the gas channel provided inside the upper suction film plate 120 is evacuated through the air extraction pipe 4. The edge of the film 300 surrounding the powder area will be firmly adsorbed to the lower plate surface of the upper suction film plate 120 by the air extraction hole 130 provided on the lower plate surface of the upper suction film plate 120. Subsequently, the plate clamping mechanism 2 of the conveying component 200 clamps the upper plate of the suction film 120, and the film clamping mechanism 3 of the conveying component 200, together with the upper plate of the suction film 120, clamps the edge of the film covering 300 surrounding the powder area. Then, the robotic arm moves the upper plate of the suction film 120 to achieve stable transportation of the powder material.

[0029] The powder handling mechanism provided in this embodiment is structurally designed from both the aspects of film suction and film clamping through the film suction component 100 and the handling component 200. This ensures the stability of powder distribution on the surface of the film 300 during the powdering and subsequent transportation of the powder-coated film 300, reducing problems such as powder falling off the film 300 or uneven powder distribution caused by warping and vibration of the film 300.

[0030] This powder handling mechanism can be applied to powder compression and packaging equipment, with the same effect as described above. When the powder is resin powder, the powder handling mechanism and powder compression and packaging equipment, when applied to electronic product packaging production lines, can improve the yield of packaged products.

[0031] It should be noted that, in this embodiment, the upper suction plate 120 and the lower suction plate 110 are respectively provided with at least one interface hole 140 and multiple suction holes 130 communicating with the gas channels provided inside their respective plates. The suction holes 130 are designed to be located on the lower plate surface of the upper suction plate 120 and the upper plate surface of the lower suction plate 110, as described above. The interface holes can be located on any side of the upper suction plate 120 and the lower suction plate 110, for sealing connection with the interface of the gas pipeline of the vacuum equipment.

[0032] The suction pipe 4 serves as a vacuuming pipe. One end of its pipe is used for a sealed connection with the interface of the gas pipe of an external vacuuming device, and the other end is used for a sealed connection with the interface hole of the gas channel inside the upper plate 120. Optionally, a vacuum nozzle 41 can be connected to the lower end of the suction pipe 4. During connection, the vacuum nozzle 41 covers the outside of the interface hole of the gas channel inside the upper plate 120 to seal with the interface hole of the gas channel in the upper plate 120. The negative pressure provided by the vacuum nozzle 41 improves the connection stability between the interface of the suction pipe 4 and the gas channel in the upper plate 120, and quickly evacuates the gas channel in the upper plate 120.

[0033] In addition, in some optional embodiments of this embodiment, the film suction assembly 100 further includes a fixing pin, which can fix the upper film suction plate 120 to the upper layer of the lower film suction plate 110. The fixing pin can be fixed to either the upper film suction plate 120 or the lower film suction plate 110, and the other is provided with a pin hole for alignment. In some other optional embodiments of this embodiment, one of the upper plate surface of the lower film suction plate 110 and the lower plate surface of the upper film suction plate 120 is provided with a fixing protrusion, and the other is provided with a fixing hole. The fixing protrusion can be inserted into the fixing hole to fix the upper film suction plate 120 to the upper layer of the lower film suction plate 110.

[0034] These optional structures ensure that the upper suction plate 120 and the lower suction plate 110 do not misalign during the powder application process, ensuring that the powder-applied area of ​​the film 300 is always supported by the lower suction plate 110, thus guaranteeing the flatness of the film 300 and the uniformity of powder application.

[0035] Reference Figure 4 and Figure 5 In an optional embodiment of this example, the mounting frame 1 includes a base plate 11 and two fixed seats 12 fixedly connected to opposite sides of the base plate 11; the base plate 11 and / or the two fixed seats 12 are fixed to the end effector of the robotic arm (here, "and / or" means that either the base plate 11 or the two fixed seats 12 are fixed to the end effector of the robotic arm, or the base plate 11 and the two fixed seats 12 are both fixed to the end effector of the robotic handle); the air extraction pipe 4 and the plate clamping mechanism 2 are both mounted on the base plate 11; the membrane clamping mechanism 3 is mounted on the two fixed seats 12.

[0036] Furthermore, in some optional embodiments, the mounting frame 1 also includes a fixing pin 2, which can fix the upper film suction plate 120 to the lower layer of the base plate 11. The fixing pin 2 can be fixed to either the base plate 11 or the upper film suction plate 120, and the other has a pin hole for alignment. In other optional embodiments, a fixing protrusion 2 is provided on one of the lower plate surface of the base plate 11 and the upper plate surface of the upper film suction plate 120, and a fixing hole 2 is provided on the other. The fixing protrusion 2 can be inserted into the fixing hole 2 to fix the base plate 11 to the upper layer of the upper film suction plate 120, and to seal the interface between the suction pipe 4 and the gas channel provided inside the upper film suction plate 120. These optional structures can ensure that the upper film suction plate 120 and the base plate 11 of the mounting frame 1 do not misalign during the handling of the upper film suction plate 120 and the film covering 300, thereby improving the stability of handling.

[0037] Continue to refer to Figure 4 and Figure 5In an optional embodiment of this example, the plate clamping mechanism 2 includes at least one set of plate clamping components 20; each set of plate clamping components 20 includes a finger clamping cylinder 21 and two hooks 22; the finger clamping cylinder 21 is fixed to the base plate 11; the two hooks 22 are rotatably mounted on both sides of the base plate 11 and are connected to the two output ends of the corresponding finger clamping cylinder 21 in a one-to-one transmission connection, so as to open or close under the control of the finger clamping cylinder 21. A finger-grip cylinder (also commonly referred to as a finger cylinder or gripper cylinder) is an existing automated actuator that uses compressed air as a power source. Driven by a cylinder, it enables two or more "finger" (output end) to open and close, thereby opening or closing the hooks 22 connected to its two output ends. The hooks 22 are rotatably mounted on both sides of the base plate 11 via a rotating shaft, which limits the rotational position of the hooks 22 relative to the base plate 11. When the base plate 11 is moved above the suction film plate 120, the hooks 22 open when the lower ends of the two hooks 22 rotate in opposite directions. Moving the base plate 11 downwards so that the suction film plate 120 is located between the two hooks 22, the two hooks 22 rotate towards each other relative to the base plate 11, thus gripping the suction film plate 120 located between the two hooks 22.

[0038] In this optional embodiment, the finger-grip cylinder 21 and the two hooks 22 work together, and the rotational position of the hooks 22 relative to the base plate 11 is limited, so that the upper film suction plate 120 can be accurately gripped and positioned. At the same time, the finger-grip cylinder 21 uses compressed air as a power source to drive the two hooks 22 to open and close, which can ensure that the upper film suction plate 120 is firmly and accurately gripped during the transportation process, and ensure the stability and reliability of the gripping process.

[0039] Reference Figure 6 , combined Figure 1 and Figure 2 In an optional embodiment of this example, the membrane clamping mechanism 3 includes two sets of membrane clamping assemblies 30, which are respectively mounted on two fixed seats 12. Each fixed seat 12 includes a support 121 fixedly or integrally connected to the base plate 11 and a top plate 122 fixedly or integrally connected to one side of the support 121; the top plate 122 extends horizontally away from the base plate 11, and a linear guide rail 1221 extending horizontally is provided on the lower surface of the top plate 122, and the central axes of the linear guide rails 1221 provided on the two top plates 122 coincide. Each membrane clamping assembly 30 includes a connecting seat 31, a lifting assembly 32, and a clamping plate 33. A slider 1222 is slidably connected to the aforementioned linear guide rail 1221, and the connecting seat 31 is fixed or integrally connected to the slider 1222. One end of the lifting assembly 32 is connected to the connecting seat 31, and the other end is connected to the clamping plate 33, which is used to drive the clamping plate 33 to rise and fall relative to the connecting seat 31. The lower end of the clamping plate 33 is bent toward the side of the base plate 11 to form a film-coated clamping part 331.

[0040] In use, the distance between the clamping plates 33 of the two sets of film clamping assemblies 30 can be adjusted by adjusting the position of the slider 1222 on the linear guide rail 1221, so that the distance is slightly larger than the width of the upper film suction plate 120. After adjustment, the slider 1222 is fixed. In the initial state, the lifting assembly 32 drives the clamping plate 33 to move downwards, so that the film-coating clamping part 331 at the lower end of the clamping plate 33 is below the height of the lower surface of the upper film suction plate 120 when it is clamped by the plate clamping mechanism 2. After the upper film suction plate 120 is clamped by the plate clamping mechanism 2, the lifting assembly 32 drives the clamping plate 33 to move upwards, so that the upper surface of the film-coating clamping part 331 at the lower end of the clamping plate 33 is in contact with the lower surface of the film 300 adsorbed on the lower surface of the upper film suction plate 120. The edge area of ​​the film 300 surrounding the powder-sprinkled area can then be clamped between the lower surface of the upper film suction plate 120 and the upper surface of the film-coating clamping part 331, realizing the function of the film clamping mechanism 3 cooperating with the upper film suction plate 120 to clamp the film 300. This optional embodiment can ensure that the film 300 remains flat during the clamping process, avoiding deformation or damage to the film due to uneven clamping.

[0041] More specifically, continue to refer to Figure 6 In an optional embodiment of this example, the lifting assembly 32 includes a drive unit 321, a telescopic rod 322, and a lifting plate 323. The telescopic rod 322 extends vertically, with its lower end connected to the drive unit 321 and its upper end fixedly connected to the lifting plate 323. The lifting plate 323 is fixedly connected to the upper end of the clamping plate 33. The drive unit 321 is fixedly connected to the connecting seat 31 and is used to drive the telescopic rod 322 to extend and retract, thereby raising and lowering the lifting plate 323, and thus raising and lowering the clamping plate 33. The drive unit 321 and the telescopic rod 322 can be, but are not limited to, a cylinder-piston rod assembly, a hydraulic cylinder-piston rod assembly, or an electric push rod-ball screw nut assembly, etc., as lifting structures.

[0042] Reference Figure 4 and Figure 5 In an optional embodiment of this invention, each top plate 122 has two parallel linear guide rails 1221 on its lower surface, and each linear guide rail 1221 has a slider 1222 slidably connected to it; see reference Figure 6The aforementioned connecting seat 31 includes a fixed plate 311, two adjusting fixing blocks 312, and two connecting blocks 313; the driving part 321 is fixedly connected to the fixed plate 311; the two connecting blocks 313 are fixedly connected to both ends of the fixed plate 311, and one of the connecting blocks 313 is fixedly or integrally connected to a slider 1222, and the other connecting block 313 is fixedly or integrally connected to another slider 1222; the adjusting fixing block 312 is fixedly connected to the fixed plate 311, and a sliding limiting structure 34 is provided between the adjusting fixing block 312 and the base plate 11. The sliding limiting structure 34 is used to fix the adjusting fixing block 312 to the base plate 11 when the adjusting fixing block 312 slides into place along the extension direction of the linear guide rail 1221. Optionally, but not limited to, the sliding limit structure 34 includes a through hole on the adjusting fixing block 312, an elongated hole on the base plate 11 extending along the extension direction of the linear guide rail 1221, and a bolt and nut assembly. When the bolt passes through the aforementioned through hole and elongated hole and is locked by the nut, the adjusting fixing block 312 can be fixed to the base plate 11. Before the nut is locked, the bolt can slide along the elongated hole.

[0043] This optional embodiment improves the stability of the lifting component 32 during lifting and lowering operations in each membrane clamping assembly 30. Simultaneously, the design of the adjusting fixing block 312 ensures that it can be fixed after sliding back and forth along the extension direction of the linear guide rail 1221, further guaranteeing the stability and consistency of the clamping position. Of course, in other optional embodiments of this example, the adjusting fixing block 312 may not be designed; instead, the slider 1222 can be fixed by frictional engagement with the linear guide rail 1221. Alternatively, a positioning pin can be used to position the slider 1222 on the linear guide rail 1221 when the adjustment is complete, or other positioning measures can be adopted.

[0044] Reference Figure 5 In an optional embodiment of this example, a detection component 5 is also installed on the base plate 11. This detection component 5 includes a probe 51 and a sensor 52 electrically connected to the probe 51. The probe 51 is used to detect whether the lower surface of the base plate 11 is in contact with the upper film suction plate 120. The plate clamping mechanism 2 also has a control unit, and the sensor 52 is signal-connected to its control unit. When the probe 51 detects that the lower surface of the base plate 11 is in contact with the upper film suction plate 120, the control unit controls the plate clamping mechanism 2 to clamp the upper film suction plate 120. This control unit is located in the controller and is electrically or signal-connected to the drive unit (e.g., the aforementioned finger-clamping cylinder 21) located in the plate clamping mechanism 2, controlling the operation of its drive unit. This optional embodiment can accurately determine the position of the upper film suction plate 120 before the plate clamping mechanism 2 performs the clamping operation, avoiding the problem of the plate clamping mechanism 2 failing to clamp the upper film suction plate 120 and causing no-load operation, thus improving the clamping accuracy and reliability of the plate clamping mechanism 2.
