Description

Technical Field

[0001] This invention relates to the field of tooling technology for electronic device manufacturing, and in particular to an IGBT module terminal ejection device and method. Background Technology

[0002] As a core semiconductor device for power conversion and control, IGBT modules require precise positioning of the power terminals using a terminal reflow fixture during their packaging and manufacturing process. After reflow soldering, the formed IGBT module needs to be separated from the terminal reflow fixture for subsequent processes such as molded casing installation and performance testing. Currently, the industry commonly uses manual operation for this separation process, where operators press the power terminals on the module with their fingers to gradually detach the tightly fitted IGBT module from the terminal reflow fixture.

[0003] However, the aforementioned existing technologies have obvious technical defects in the manual separation method. It is difficult to keep the angle and force of manual pressing uniform, which can easily cause the perpendicularity deviation between the power terminal and the copper base plate after separation. This directly affects the installation and fitting accuracy of the subsequent plastic shell and increases the product defect rate. At the same time, the long-term repetitive finger pressing action can easily cause finger joint strain of operators, and the separation efficiency of a single station is low, which cannot adapt to the production rhythm of large-scale mass production.

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] Please see Figures 1 to 8 This invention provides an IGBT module terminal ejection device, including a base 1 and an ejection assembly; the ejection assembly includes a U-shaped pressing block 2, a carrier plate 3, multiple locking units, two removal units, and multiple ejection blocks 4.

[0029] In this embodiment, the base 1 provides a rigid bearing foundation and installation reference for the entire device; the U-shaped pressing block 2 is a pressing actuator, which adopts a U-shaped opening structure to avoid the power terminals, while applying pressure evenly to the surface of the terminal connection plate to ensure stable pressing force; the carrier plate 3 is a workpiece positioning and bearing platform, providing precise placement and positioning for the IGBT module; multiple locking units are used to quickly lock and fix the terminal return fixture to prevent the workpiece from shifting or deviating during the ejection process; two removal units are symmetrically arranged to automatically and smoothly remove the workpiece from the workstation after ejection, connecting upstream and downstream processes; multiple ejection blocks 4 are fixedly installed on the base and coaxially arranged corresponding to the power terminals. When the carrier plate moves the workpiece downward, the ejection blocks push the power terminals out of the fixture in the opposite direction; through the coordinated operation of the above structures, the mechanized ejection and separation of the IGBT module power terminals is realized, completely replacing manual operation, ensuring uniform ejection force angle and force, effectively ensuring the verticality of the power terminal installation, reducing the product defect rate, and significantly improving the efficiency of single-station separation operation, adapting to the production rhythm of large-scale mass production.

[0030] Furthermore, the IGBT module 5 includes a terminal connection plate 6, multiple power terminals 7, and a terminal return fixture 8. Multiple power terminals 7 are installed on the terminal connection plate 6, and the multiple power terminals 7 are inserted into the terminal return fixture 8. The terminal return fixture 8 is placed inside the carrier plate 3, and each power terminal 7 is aligned with the corresponding ejector block 4.

[0031] In this embodiment, the terminal connection plate 6 is the insulating substrate of the IGBT module and serves as the welding carrier for the power terminals; the multiple power terminals 7 are conductive connection pins that are tightly fitted into the positioning holes of the terminal reflow fixture 8 after reflow soldering; the terminal reflow fixture 8 is a welding positioning jig used to precisely fix the position of all power terminals during the reflow soldering process; each power terminal 7 has a corresponding ejector block 4 directly below it to ensure that the terminal is subjected to axial positive pressure during ejection, avoiding bending and vertical deviation caused by lateral force, and ensuring the shape and position accuracy of the ejected terminal.

[0032] Furthermore, the ejection assembly also includes a pressing mechanism, which is disposed above the base 1; the pressing mechanism includes a bracket 9, a pressing cylinder 10, and a mounting plate 11, the bracket 9 is mounted on one side of the carrier plate 3, the pressing cylinder 10 is disposed on one side of the bracket 9, the output end of the pressing cylinder 10 is provided with the mounting plate 11, and the U-shaped pressing block 2 is detachably connected to the mounting plate; an operation panel 12 and a control module 13 are disposed on one side of the bracket 9, and the operation panel 12 and the control module 13 are sequentially disposed on the bracket 9.

[0033] In this embodiment, the bracket 9 is a portal frame that provides stable reaction force support for the pressing mechanism. A pressure sensor is also provided at the output end of the pressing cylinder 10 to detect the pressure value and control the pressing force within a preset range to avoid overpressure damage to the device. The pressing cylinder 10 is a downward pressing power source with stable output pressure and controllable stroke, which can accurately control the ejection stroke and downward force. The mounting plate 11 is an adapter mounting plate, and the U-shaped pressing block 2 adopts a detachable connection method, which can quickly replace the pressing block of the corresponding specification according to different IGBT modules, improving the versatility of the device. The operation panel 12 is a human-machine interface used to set operating parameters and start and stop the device. The control module 13 is the control core of the device, which can link and control the action sequence of all execution components such as pressing, locking, and removal to ensure precise connection of each process and stable and reliable operation.

[0034] Furthermore, the ejection assembly also includes two clamping units, which are symmetrically arranged on the U-shaped pressing block 2. Each clamping unit includes a clamping plate 14 and a clamping drive component 15. The clamping drive component 15 is disposed at one end of the U-shaped pressing block 2, and its output end passes through the U-shaped pressing block 2 and is fixedly connected to the clamping plate 14.

[0035] In this embodiment, the two clamping units are symmetrically arranged on both sides of the U-shaped pressing block 2, which can pre-clamp the two side walls of the terminal connecting plate 6 before pressing out, assisting in correcting the workpiece position and ensuring that the workpiece does not shift when pressing down; the clamping drive component 15 is a miniature drive cylinder, which can drive the clamping plate 14 to perform radial reciprocating motion to achieve clamping and releasing of the workpiece; the clamping positioning and pressing out are integrated on the same component, with high positioning accuracy and compact structure.

[0036] Furthermore, the locking unit includes a locking plate 16, a locking spring 17, a locking slide rod 18, and an electromagnet 19. The locking plate 16 is located inside the carrier plate 3. The locking slide rod 18 is slidably connected to the carrier plate 3. One end of the locking slide rod 18 is fixedly connected to the locking plate 16. Both ends of the locking spring 17 are movably connected to the locking plate 16 and the inner sidewall of the carrier plate 3, respectively. The locking spring 17 is sleeved on the outside of the locking slide rod 18. The electromagnet 19 is disposed on the inner sidewall of the carrier plate 3. The electromagnet 19 and the locking plate 16 attract each other. The locking plate 16 and the terminal return fixture 8 abut against each other.

[0037] In this embodiment, the locking plate 16 is an actuator that directly abuts against and locks, with its end face conforming to the side wall of the terminal return fixture 8; the locking slide rod 18 is a sliding guide component that ensures that the locking plate 16 moves smoothly back and forth in a straight line without deflection; the locking spring 17 provides a continuous preload thrust, which pushes the locking plate 16 out under normal conditions to abut against the terminal return fixture 8 to achieve locking; the electromagnet 19 generates magnetic force when energized, attracting the locking plate 16 to retract backward against the spring force, thereby achieving automatic unlocking; this locking structure requires no manual operation, is reliable in locking and fast in unlocking, and can realize the rapid clamping and release of workpieces.

[0038] Furthermore, the locking unit also includes a limiting plate 20 and a top inclined plate 21. The limiting plate 20 is disposed on one side of the locking plate 16, and the top inclined plate 21 is disposed above the locking plate 16.

[0039] In this embodiment, the limiting plate 20 is used to limit the maximum extension stroke of the locking plate 16, preventing the locking plate from over-extending and disengaging from the slide, and ensuring accurate movement stroke; the top inclined plate 21 has a guide slope, when the terminal return fixture 8 is placed into the carrier 3 from top to bottom, the bottom of the fixture can press down along the slope to automatically push open the locking plate 16. After the workpiece is placed, the locking plate 16 automatically springs back and locks under the action of spring force, realizing locking upon placement without additional unlocking operation, greatly improving loading efficiency.

[0040] Furthermore, the removal unit includes a removal telescopic component 22, a removal frame 23, and multiple removal mechanisms. The removal telescopic component 22 is disposed on the outside of the carrier tray 3, and its output end passes through the carrier tray 3 and is fixedly connected to the removal frame 23. The multiple removal mechanisms are sequentially disposed on the removal frame 23. Each removal mechanism includes a removal driving component 24 and a removal wheel 25. The removal driving component 24 is disposed above the removal frame 23, and its output end is fixedly connected to the removal wheel 25. The removal wheel 25 is located inside the removal frame 23.

[0041] In this embodiment, the telescopic component 22 is a telescopic drive component that can drive the entire removal frame 23 to perform radial reciprocating motion. During the ejection operation, it retracts to avoid interference with the lifting and lowering of the workpiece, and extends to support the bottom of the workpiece during discharge. Multiple removal mechanisms are arranged sequentially along the workpiece conveying direction. The removal drive component 24 is a micro drive motor that can drive the removal wheel 25 to rotate. The surface of the removal wheel 25 is made of a high-friction material. When rotating, it relies on friction to drive the workpiece to move smoothly out of the carrier plate 3, realizing automatic discharge after ejection without manual removal, thus improving the degree of automation of the operation.

[0042] Furthermore, the carrier plate 3 is provided with a plurality of stabilizing slide rods 26 and a plurality of rebound mechanisms. The plurality of rebound mechanisms are sequentially arranged between the carrier plate 3 and the base 1. One end of each of the plurality of stabilizing slide rods 26 is fixedly connected to the base 1, and the other end of each of the plurality of stabilizing slide rods 26 is slidably connected to the carrier plate 3. The rebound mechanism includes a rebound slide rod 27 and a rebound spring 28. One end of the rebound slide rod 27 is slidably connected to the carrier plate 3, and the other end of the rebound slide rod 27 is fixedly connected to the base 1. The two ends of the rebound spring 28 are movably connected to the lower part of the base 1 and the carrier plate 3, respectively, and the rebound spring 28 is sleeved on the outside of the rebound slide rod 27.

[0043] In this embodiment, multiple stabilizing slide bars 26 provide precise vertical guidance for the up-and-down floating of the carrier plate 3, ensuring that the carrier plate 3 always remains horizontal during lifting and lowering without tilting or deflection, thus ensuring accurate ejection position. Multiple rebound mechanisms are evenly distributed. After the pressing and ejection are completed and the pressing block rises, the rebound spring 28 releases its elastic potential energy, pushing the carrier plate 3 to automatically rise and reset, so that the ejection block 4 completely detaches from the bottom of the workpiece, providing clearance for the workpiece to move out of the clearance space. The rebound slide bar 27 provides radial limit for the rebound spring 28, preventing the spring from deforming radially under pressure and extending its service life.

[0044] Furthermore, the ejection assembly also includes a tooling conveyor 29, a terminal conveyor 30, and a side adjustment mechanism. The tooling conveyor 29 is disposed on the base 1 and located at one end of the carrier 3. The terminal conveyor 30 and the side adjustment mechanism are disposed on one side of the carrier 3. The side adjustment mechanism includes a side moving component 31 and a reinforcing frame 32. The side moving component 31 is disposed on one side of the carrier 3, and the output end of the side moving component 31 is fixedly connected to the reinforcing frame 32. The terminal conveyor 30 is disposed above the reinforcing frame 32.

[0045] In this embodiment, the tooling conveyor 29 is an automatic feeding conveyor line that can continuously transport the IGBT modules to be ejected to the carrier tray 3 station to achieve batch continuous operation; the terminal conveyor 30 is used to receive the power terminals after ejection and separation, collect the terminals and transfer them to the next process; the side moving component 31 can drive the reinforcing frame 32 to move laterally, adjust the receiving position of the terminal conveyor 30, and adapt to the terminal arrangement of different specifications of workpieces; the reinforcing frame 32 is a rigid mounting frame, which improves the installation stability of the terminal conveyor 30, ensures a smooth receiving process, and avoids terminals falling or being damaged by impact.

[0046] When using the IGBT module terminal ejection device of this embodiment, the operator starts the equipment through the operation panel 12, and the control module 13 controls all components to reset to the initial state; the electromagnet 19 is energized to attract the locking plate 16 to retract and unlock, the return spring 28 pushes the carrier plate 3 to a high-position reset state, and the ejection unit is in a retracted avoidance state; the tooling conveyor 29 transports the IGBT module 5 to be processed to the top of the carrier plate 3, and the workpiece falls into the inside of the carrier plate 3; the terminal return tooling 8 presses down the top inclined clamping plate. The inclined surface of 21 automatically pushes open the locking plate 16. After the workpiece is fully in place, the electromagnet 19 is de-energized, and the locking spring 17 pushes the locking plate 16 out to press against the side wall of the terminal return fixture 8, locking the IGBT module 5 in the carrier plate 3. The pressing cylinder 10 is activated, driving the mounting plate 11 and the U-shaped pressing block 2 to move downward. During the downward movement, the two clamping drive components 15 synchronously drive the clamping plates 14 to extend towards each other, clamping the two sides of the terminal connecting plate 6 and correcting the workpiece position. The U-shaped pressing block 2 Continue pressing down, pushing the carrier plate 3 downward along the stabilizing slide bar 26, compressing the return spring 28; the multiple ejector blocks 4 fixed on the base 1 extend into the holes of the terminal return fixture 8, synchronously ejecting the multiple power terminals 7 from the fixture upward, separating them from the terminal connecting plate 6; after ejection, the operator operates an external material handling device to remove the ejected power terminals 7 and transfer them to the terminal conveyor 30 for centralized conveying; the pressing cylinder 10 drives the U-shaped pressing block 2 to rise and reset; the return spring 28 pushes the... The carrier plate 3 rises back to its initial height along the stabilizing slide bar 26, and the ejector block 4 completely detaches from the workpiece; the removal telescopic component 22 drives the removal frame 23 to extend inward, so that the removal wheel 25 supports the bottom of the terminal return fixture 8; the removal drive component 24 is activated, driving the removal wheel 25 to rotate, and relying on friction, the IGBT module 5 with the terminals removed is smoothly removed from the carrier plate 3 and flows into the downstream process so that subsequent workpieces can continue to be ejected; by repeating the above steps, the continuous mechanized ejection and separation operation of the IGBT module terminals can be realized.

[0047] Please see Figure 9 The present invention also provides a method for ejecting IGBT module terminals, comprising the following steps: S1: placing the IGBT module 5 on the carrier plate 3; S2: locking and fixing the IGBT module 5 by the locking unit; S3: moving the U-shaped pressing block 2 downward, moving the IGBT module downward to contact the ejection block 4, so that the terminals are ejected; S4: the operator uses other equipment to remove the ejected terminals; S5: the removal unit removes the IGBT module 5 with the terminals removed, so that the ejection operation can be continued subsequently.

[0048] The process involves placing the IGBT module 5 on the carrier plate 3, locking the IGBT module 5 in place using the locking unit, moving the U-shaped pressing block 2 downwards to bring the IGBT module into contact with the ejector block 4, thus ejecting the terminals, and having the operator remove the ejected terminals using other equipment. The removal unit then removes the IGBT module 5 with the terminals removed so that subsequent ejection operations can continue.
