Description

Technical Field

[0001] This invention belongs to the field of IGBT wiring technology, and particularly relates to a wire binding device for IGBT wiring and its usage method. Background Technology

[0002] The typical packaging process for IGBT modules is as follows: soldering and binding the chip and DBC (copper-clad ceramic plate) → soldering the DBC and copper base plate → installing the casing → potting silicone → sealing → final testing.

[0003] The traditional method for soldering and bonding chips and DBCs is to place the chip and DBC in a frame-type fixture plate. Inside the frame, there are two push plates that are locked with bolts. During the installation process, the DBC and chip are first placed between the push plates, and then the two push plates are moved closer to each other by rotating the bolts until the DBC and chip are clamped and fixed.

[0004] The aforementioned tooling board is not only complex to operate, but each type of tooling can only be used to bond one type of chip and DBC. For chips and DBCs of different sizes, specific designs are required based on their dimensions, resulting in high production costs.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a wire-binding device for IGBT wiring and its usage method. The device involves placing the chip and DBC to be bound onto a fixing component, with both ends resting on two placement platforms. A rotating drive block controls the two placement platforms to move closer together until the chip and DBC are fixed in place. Furthermore, the feeding component can center-grip the module to be bound, facilitating precise positioning during placement. This wire-binding device is not only simple to operate but also applicable to binding modules of any size, saving costs.

[0007] To achieve the above objectives, the present invention proposes a wire binding device for IGBT wiring. The wire binding device includes a worktable, on which a fixing component for fixing the module to be bound is slidably disposed, and a feeding component for feeding the module to be bound is also fixed on the worktable.

[0008] The workbench has a groove, the fixing component is located in the groove, and there are two linearly distributed slide rails at the beginning of the groove.

[0009] The fixing component includes two sliding blocks, which slide within corresponding slide rails, and a placement platform is fixed above the sliding blocks.

[0010] A drive block is rotatably mounted on one side of the worktable. A double-ended lead screw that is threadedly engaged with the sliding block is fixed on the drive block. A slot is provided on the side of the drive block away from the worktable.

[0011] Furthermore, a connecting plate is fixed to one side of the workbench.

[0012] The feeding component includes a first cylinder fixed below the connecting plate. The output shaft of the first cylinder passes through the connecting plate and is fixed to a first drive box. A first motor is fixed inside the first drive box. The output shaft of the first motor passes through the top plate of the first drive box and is vertically fixed to a first electric telescopic rod. A first connecting rod is vertically fixed below the output shaft of the first electric telescopic rod.

[0013] A second drive box is fixed below the first connecting rod, and a second motor is fixed inside the second drive box. The second motor passes through the bottom plate of the second drive box and is fixed with a connecting block. Symmetrically distributed connecting pieces are fixed on both sides of the connecting block. Rotating holes are opened on the connecting pieces. The feeding component also includes two rod sleeves, which are located on both sides of the connecting block. A rotating shaft located in the rotating hole is vertically fixed at one end of the rod sleeve, and a sliding rod is fitted on the other end. The sliding rod is slidably connected to the rod sleeve.

[0014] The sliding rod is vertically fixed to a first fixing plate at the end away from the sleeve, and a second fixing plate is fixed to the sleeve. A spring is fixedly connected between the first fixing plate and the sleeve.

[0015] Each of the two first fixing plates is fixed with a clamping arm, and the two clamping arms are opposite each other.

[0016] Furthermore, a second electric telescopic rod for pushing one end of the first fixed plate is fixed on the second fixed plate, and the output shaft of the second electric telescopic rod faces the first fixed plate.

[0017] Furthermore, the clamping arm includes a third electric telescopic rod fixed to the first fixed plate. The third electric telescopic rod is parallel to the sliding rod. A third drive box is fixed on the output shaft of the third electric telescopic rod. A third motor is fixed inside the third drive box. The output shaft of the third motor passes through the side plate of the third drive box away from the third electric telescopic rod and is vertically fixed to a clamping plate. A limit plate is vertically fixed on the side of the clamping plate away from the third motor and is fixed in the middle position of the clamping plate.

[0018] Furthermore, horizontal limiting plates are fixed on both sides of the connecting block, and the limiting plates are located below the rod sleeve.

[0019] Furthermore, a distance sensor is fixed on the second fixing plate, which is used to detect the distance between the second fixing plate and the first fixing plate.

[0020] Furthermore, the placement platform is L-shaped.

[0021] A method of using a wire-binding device for IGBT wiring, the method comprising the following steps:

[0022] S1: Loading materials;

[0023] By activating the second electric telescopic rod, the two clamping plates move away from each other. By activating the third motor, the limiting plate is adjusted to a horizontal position. The limiting plate is adjusted to both sides of the module to be bound by the first motor, the first electric telescopic rod, the second motor, and the first cylinder in coordination. The limiting plate is pressed onto the top of the module to be bound by the first cylinder. By activating the third electric telescopic rod, its output end is disengaged from the first fixing plate. Under the action of the spring, the two clamping plates move closer to each other to clamp the module to be bound.

[0024] The distance between the two clamping plates is calculated by measuring the distance detected by the distance sensor. The two first fixed plates are pushed away from each other by extending the second electric telescopic rod. The connecting block is rotated 90° by starting the second motor to adjust the orientation of the clamping arm. The module to be bound is clamped again by starting the second electric telescopic rod, and the current distance detected by the distance sensor is recorded.

[0025] The module to be bound is clamped by activating the first cylinder. The clamping plate is rotated by activating the third motor, so that the limiting plate is adjusted to be below the module to be bound. The module to be bound is transferred to the corresponding fixing part by adjusting the first motor and the first electric telescopic rod. The orientation of the module to be bound is adjusted by activating the second motor. The orientation of the module to be bound is adjusted by activating the third motor. The two ends of the module to be bound are placed on the two placement platforms by retracting the first cylinder. The module to be bound is released by extending the second electric telescopic rod.

[0026] S2: Secure the module to be bound on the fastener;

[0027] By starting the first motor, the first electric telescopic rod is adjusted to be parallel to the side of the worktable. By cooperating with the first cylinder and the first electric telescopic rod, one of the limiting plates is adjusted to correspond to the slot on the drive block to be driven.

[0028] By extending the corresponding third electric telescopic rod, the lowering limit plate is inserted into the corresponding slot. The third motor is then activated to push the two placement platforms closer together until the module to be bound is fixed.

[0029] S3: Begin aluminum wire bonding processing for the module to be bonded.

[0030] The IGBT wiring binding device and its usage method proposed in this invention can bring the following beneficial effects:

[0031] 1. The wire binding device of the present invention places the chip and DBC to be bound on the fixing component. During placement, the two ends of the chip and DBC rest on two placement platforms respectively. The two placement platforms are brought closer together by rotating the drive block until the chip and DBC are fixed. The feeding component can clamp the module to be bound in the center, which facilitates accurate positioning of the module to be bound during placement. This makes the wire binding device not only simple to operate, but also applicable to binding modules of any size, saving costs.

[0032] 2. The binding device of the present invention can not only load materials by setting up a feeding component, but also measure the size of the module to be bound during loading. When the fixing component fixes the module to be bound, it can reasonably control the moving distance of the placement platform according to the size of the module to be bound, so as to fix the module to be bound without crushing it.

[0033] 3. The binding device of the present invention, by setting a third motor, can control the rotation of the clamping plate after the module to be bound is clamped, so that the limiting plate is adjusted to the bottom of the module to be bound to prevent the module to be bound from falling during transportation. It can also adjust the orientation of the module to be bound before placing it. Furthermore, it can control the rotation of the drive block to control the distance between the two placement platforms after the limiting plate is inserted into the slot.

The feeding component 3 also includes two rod sleeves 312. The two rod sleeves 312 are located on both sides of the connecting block 38. A rotating shaft 311 that rotates in the rotating hole 310 is vertically fixed at one end of the rod sleeve 312. A sliding rod 314 is fitted on the other end. The sliding rod 314 is slidably connected to the rod sleeve 312. A horizontal limiting piece 313 is fixed on both sides of the connecting block 38.

[0051] A first fixing plate 315 is vertically fixed to the end of the sliding rod 314 away from the rod sleeve 312. A second fixing plate 317 is fixed to the rod sleeve 312.

[0054] A method for using a wire-binding device for IGBT wiring, comprising the following steps:

[0055] S1: Loading materials;

[0056] By activating the second electric telescopic rod 318, the two first fixed plates 315 are pushed away from each other, thereby causing the two clamping plates 323 to move away from each other. By activating the third motor 322, the limiting plate 324 is adjusted to be horizontal. By coordinating the first motor 33, the first electric telescopic rod 34, the second motor 37, and the first cylinder 31, the limiting plate 313 is adjusted to both sides of the module 10 to be bound. By retracting the first cylinder 31, the limiting plate 324 is pressed above the module 10 to be bound. By activating the third electric telescopic rod 320, its output end is disengaged from the first fixed plate 315. Under the action of the spring 316, the two clamping plates 323 move closer to each other to clamp the module 10 to be bound. When clamping the stacked modules 10 to be bound, due to the restriction of the limiting plate 324, the clamping plate 323 can only clamp the topmost module 10 to be bound.

[0057] The distance between the two clamping plates 323 is calculated by the distance sensor 319, which is the distance between the two sides of the module 10 to be bound. The two first fixing plates 315 are pushed away from each other by extending the second electric telescopic rod 318. The connecting block 38 is rotated 90° by starting the second motor 37 to adjust the orientation of the clamping arm. The module 10 to be bound is clamped again by starting the second electric telescopic rod 318, and the distance detected by the distance sensor 319 is recorded. This not only allows the module 10 to be bound to be clamped in the center, making it easier to position the module 10 when it is placed later, but also allows for the measurement of the size of the module 10 to be bound.

[0058] The first cylinder 31 is activated to clamp the module 10 to be bound. The third motor 322 is activated to control the rotation of the clamping plate 323, so that the limiting plate 324 is adjusted to be below the module 10 to be bound, so as to prevent the module 10 to be bound from falling during the transfer. The first motor 33 and the first electric telescopic rod 34 are used to adjust and transfer the module 10 to be bound to the corresponding fixing part 2. The second motor 37 is activated to adjust the position of the module 10 to be bound. The third motor 322 is activated to adjust the orientation of the module 10 to be bound. The first cylinder 31 is retracted to place the two ends of the module 10 to be bound onto the two placement platforms 22 respectively. The second electric telescopic rod 318 is extended to release the module 10 to be bound.

[0059] S2: Secure the module 10 to be bound on the fastener 2;

[0060] By starting the first motor 33, the first electric telescopic rod 34 is adjusted to be parallel to the side of the workbench 1. By cooperating with the first cylinder 31 and the first electric telescopic rod 34, one of the limiting plates 324 is adjusted to correspond to the slot 25 on the drive block 23 to be driven. At this time, the rod sleeve 312 corresponding to the other drive block 23 rotates upward under the obstruction of the workbench 1.

[0061] By extending the corresponding third electric telescopic rod 320, the lowering limit plate 324 is inserted into the corresponding slot 25. The third motor 322 is started to control the rotation of the limit plate 324, which in turn drives the limit plate 324 and the corresponding double-headed screw 24 to rotate, thereby pushing the two placement platforms 22 closer to each other until the module 10 to be bound is fixed. During operation, the distance the placement platform 22 moves can be controlled according to the size of the module 10 to be bound, so as to fix the module 10 to be bound without crushing it.

[0062] S3: Start the aluminum wire bonding process for the module to be bound 10.

Each embodiment focuses on describing the differences from other embodiments.

Various modifications and variations can be made to the present invention by those skilled in the art.
