Description

Technical Field

[0001] The present invention belongs to the technical field of pin bending processing, and in particular, relates to an IPM module pin processing device and a processing method thereof. Background Art

[0002] IPM power module is the intelligent power module, which is an advanced power switching device with the advantages of high current density, low saturation voltage and high voltage resistance, as well as high input impedance, high switching frequency and low driving power. Moreover, IPM integrates logic, control, detection and protection circuits, which is easy to use. It not only reduces the volume and development time of the system, but also greatly enhances the reliability of the system. It adapts to the development direction of today's power devices - modularization, composite and power integrated circuits, and has been more and more widely used in the field of power electronics. The pins on the IPM module mainly have two functions: connection and communication. They are the key interfaces for the module to interact with external circuits or systems.

[0003] When installing the existing IPM module, it is necessary to bend the IPM module pins at a certain angle to facilitate the connection between the IPM module and the PCB board. However, during the use of the bending processing equipment, it was found that in order to avoid the IPM module pins from breaking due to excessive bending angles, the IPM module pins need to be bent at small angles multiple times.

[0045] The locking demoulding unit 300 includes a disc 301, which is connected to a shift roller 201. A notch 3011 is provided on the disc 301, and a pressure plate 302 is slidably provided at the bottom of the notch 3011. The pressure plate 302 is placed above the IPM module body 400. An L-shaped bracket 3031 is installed on the side wall of the pressure plate 302, and a synchronous plate 303 is installed on the L-shaped bracket 3031.

When the IPM module body 400 moves downward, the IPM module body 400 drives the top plate 1031 and the push rod 103 at the bottom to move downward, the push rod 103 can push the baffle 1032 to slide downward, the baffle 1032 squeezes the reset spring 1033 at the bottom, and the reset spring 1033 is used to facilitate the reset operation later.

[0048] Embodiment 2: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figure 1 and Figure 2 As shown, a protective cover 104 is installed on the base plate 101, and the protective cover 104 covers the bending unit 200 and the locking and demolding unit 300. The protective cover 104 serves the purpose of protection. A feeding port 1041 is opened on the front of the protective cover 104, and the feeding port 1041 corresponds to the placement plate 102. An observation window 1042 is installed on the protective cover 104, and the observation window 1042 is convenient for observing the movement of the internal structure. An inspection door 1043 is installed on the top of the protective cover 104 by bolts, and the inspection door 1043 is convenient for later maintenance operations.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in a specific embodiment, a mounting bracket 2012 is installed at the rotation center of the shift roller 201, and the mounting bracket 2012 is welded to the surface of the substrate 101. The mounting bracket 2012 mainly serves the purpose of support. An inclined rod 2013 is installed on the side wall of the mounting bracket 2012, and the end of the inclined rod 2013 is installed on the substrate 101, and the inclined rod 2013, the mounting bracket 2012 and the substrate 101 form a triangle, and the triangular structure can improve stability.

[0050] like Figure 7 , Figure 8 and Fig. 9 As shown, further, a guide slider 2032 is installed on the sliding sleeve 203, and the guide slider 2032 is slidably set on the transposition groove 2022. A flat groove 2043 is set on the positioning plate 2042, and the flat groove 2043 and the inclined groove 2044 are connected to each other. A guide protrusion 2041 is inserted on the flat groove 2043, and the guide protrusion 2041 and the vertical rod 204 are connected to each other. The end position of the inclined groove 2044 vertically corresponds to the end position of the transposition groove 2022. During the rotation of the shift roller 201, the position of the shift groove 2021 on the shift roller 201 is offset, and the shift groove 2021 is in a spiral state, so that the guide slider 2032 engaged with the shift groove 2021 has a force to move outward, and then the sliding sleeve 203, the sliding rod 2031, the arch bracket 2033 and the first bending roller 2034 can be pushed to slide outward. When the arch bracket 2033 slides, the vertical rod 204 and the guide protrusion 2041 on the arch bracket 2033 are first in the flat groove 2043. Sliding, during this stage, the first bending roller 2034 moves from above the IPM module body 400 to the pin position of the IPM module body 400, and then the guide protrusion 2041 slides in the inclined groove 2044, at which time the first bending roller 2034 has a tendency to move downward, and then the IPM module body 400 can be squeezed to move into the first bending groove 1022, achieving a bending effect, and then completing the initial bending operation, and at this time the slide bar 2031 slides inside the sleeve 203, achieving the purpose of limiting.

[0051] Embodiment 3: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figure 7 , Figure 8 and Fig. 9As shown, the arc groove 2051 and the downward groove 2052 are interconnected, a positioning slider 206 is slidably arranged on the arc groove 2051, a side plate 2061 is installed on the side wall of the positioning slider 206, and the side plate 2061 and the second bending roller 2062 are connected to each other. A limit rod 2063 is movably inserted on the side plate 2061, the bottom of the limit rod 2063 is installed on the base plate 101, and a limit plate 2064 is installed on the top of the limit rod 2063. The diameter of the limit plate 2064 is larger than the diameter of the limit rod 2063. An extrusion spring 2065 is sleeved on the limit rod 2063, one end of the extrusion spring 2065 is clamped on the base plate 101, and the other end of the extrusion spring 2065 is clamped on the bottom of the side plate 2061. When the guide slider 2032 slides to the transposition groove 2022, the first bending roller 2034 remains stationary, but the positioning slider 206 slides to the initial position of the downward displacement groove 2052. As the turntable 205 and the shift roller 201 continue to rotate, the guide slider 2032 slides along the transposition groove 2022, and does not drive the first bending roller 2034 to rotate, but the position of the downward displacement groove 2052 on the turntable 205 changes, thereby driving the positioning slider 206, the side plate 2061 and the second bending roller 2062 to move downward, and the second bending roller 2062 slides in contact with the second bending groove 1023, and presses the unbent pins on the IPM module body 400 into the second bending groove 1023, completing further bending operations.

[0052] like Figure 5 and Figure 6 As shown, in a specific embodiment, a push rod 3021 is provided on the side wall of the pressing plate 302, a positioning sleeve 3022 is inserted and provided on the pushing rod 3021, and the positioning sleeve 3022 is welded on the substrate 101, and a partition 3023 is slidably provided on the positioning sleeve 3022, one end of the partition 3023 and the pushing rod 3021 are connected to each other, and a compression spring 3024 is clamped and provided between the other end of the partition 3023 and the side wall of the positioning sleeve 3022, and the moving direction of the compression spring 3024 is the same as the moving direction of the pushing rod 3021. When the pressing plate 302 moves downward, the pushing rod 3021 on the pressing plate 302 can slide inside the positioning sleeve 3022, and at this time, the partition 3023 at the bottom of the pushing rod 3021 slides downward synchronously, and the distance between the partition 3023 and the bottom of the positioning sleeve 3022 becomes smaller, thereby squeezing the internally clamped compression spring 3024, and the compressed compression spring 3024 can facilitate the reset operation later.

[0053] The present invention also discloses a processing method of an IPM module pin processing device, the steps of which are as follows:

[0054] Step 1: Install the IPM module body 400 on the placement plate 102, and align the pins on both sides of the IPM module body 400 that need to be bent with the first bending groove 1022 and the second bending groove 1023;

[0055] Step 2: Start the driving motor 2011, and drive the shift roller 201 connected to the output shaft to rotate through the driving motor 2011, so that the position of the shift groove 2021 on the shift roller 201 is offset, and then the sliding sleeve 203 and the first bending roller 2034 slide to both sides, and the vertical rod on the first bending roller 2034 slides along the inclined groove 2044, and then the first bending roller 2034 slides along the surface of the first bending groove 1022, and the pins on the surface of the IPM module body 400 are pressed into the first bending groove 1022, thereby completing the preliminary bending operation;

[0056] Step 3: After the sliding sleeve 203 slides to the transposition groove 2022, the first bending roller 2034 remains stationary, and the second bending roller 2062 slides along the arc groove 2051 to the downward movement groove 2052, driving the second bending roller 2062 to move downward, and pressing the unbent pins on the IPM module body 400 into the second bending groove 1023, completing further bending operation;

[0057] Step 4: After the bending is completed, the shift roller 201 is rotated in the reverse direction to reset. During the rotation of the shift roller 201, the shift roller 201 drives the notch 3011 of the disk 301 to rotate. When the notch 3011 corresponds to the pressure plate 302, the pressure plate 302 moves up along the notch 3011, and the pressure plate 302 is separated from the IPM module body 400, completing the automatic unlocking operation;

[0058] Step 5: During the upward movement of the pressure plate 302, the L-shaped bracket 3031 on the side wall of the pressure plate 302 drives the synchronous plate 303 to move upward, and the top block 3032 on the synchronous plate 303 moves upward along the first bending groove 1022, so as to facilitate the separation of the bent pins and the first bending groove 1022 and facilitate later disassembly.

[0059] The implementation principles of an IPM module pin processing device and a processing method thereof of this embodiment are as follows:

[0060] First, the operator installs the IPM module body 400 on the placement plate 102 , and aligns the pins on both sides of the IPM module body 400 that need to be bent with the first bending groove 1022 and the second bending groove 1023 .

[0061] Then the operator starts the driving motor 2011, and the driving motor 2011 drives the shift roller 201 to rotate. The rotation of the shift roller 201 can drive the coaxially connected disc 301 to start rotating.

[0062] When the disc 301 rotates, the notch 3011 on the disc 301 separates from the pressure plate 302, and the disc 301 can push the pressure plate 302 to move downward, and the pressure plate 302 can be squeezed with the IPM module body 400 at the bottom to ensure that the IPM module body 400 moves downward and fits tightly with the placement plate 102.

[0063] When the IPM module body 400 moves downward, the IPM module body 400 drives the top plate 1031 and the top rod 103 at the bottom to move downward, the top rod 103 can push the baffle 1032 to slide downward, and the baffle 1032 squeezes the return spring 1033 at the bottom, and the return spring 1033 facilitates the subsequent return operation.

[0064] When the pressure plate 302 moves downward, the push rod 3021 on the pressure plate 302 can slide inside the positioning sleeve 3022. At this time, the partition 3023 at the bottom of the push rod 3021 slides downward synchronously, and the distance between the partition 3023 and the bottom of the positioning sleeve 3022 becomes smaller, thereby squeezing the compression spring 3024 clamped inside. The squeezed compression spring 3024 can facilitate the subsequent resetting operation.

[0065] During the rotation of the shift roller 201, the position of the shift groove 2021 on the shift roller 201 is offset, and the shift groove 2021 is in a spiral state, so that the guide slider 2032 engaged with the shift groove 2021 has a force to move outward, and then the sliding sleeve 203, the sliding rod 2031, the arch bracket 2033 and the first bending roller 2034 can be pushed to slide outward. When the arch bracket 2033 slides, the vertical rod 204 and the guide protrusion 2041 on the arch bracket 2033 are first in the flat groove 2043. Sliding, during this stage, the first bending roller 2034 moves from above the IPM module body 400 to the pin position of the IPM module body 400, and then the guide protrusion 2041 slides in the inclined groove 2044, at which time the first bending roller 2034 has a tendency to move downward, and then the IPM module body 400 can be squeezed to move into the first bending groove 1022, achieving a bending effect, and then completing the initial bending operation, and at this time the slide bar 2031 slides inside the sleeve 203, achieving the purpose of limiting.

[0066] When the guide slider 2032 slides to the transposition groove 2022, the first bending roller 2034 remains stationary, but the positioning slider 206 slides to the initial position of the downward displacement groove 2052. As the turntable 205 and the shift roller 201 continue to rotate, the guide slider 2032 slides along the transposition groove 2022, and does not drive the first bending roller 2034 to rotate, but the position of the downward displacement groove 2052 on the turntable 205 changes, thereby driving the positioning slider 206, the side plate 2061 and the second bending roller 2062 to move downward, and the second bending roller 2062 slides in contact with the second bending groove 1023, and presses the unbent pins on the IPM module body 400 into the second bending groove 1023, completing further bending operations.

[0067] And when the side plate 2061 moves downward, the side plate 2061 slides on the limit rod 2063, wherein the limit plate 2064 ensures that the side plate 2061 and the limit rod 2063 will not be separated, and when the side plate 2061 slides, the extrusion spring 2065 at the bottom of the side plate 2061 is compressed, and the extrusion spring 2065 is used to facilitate later resetting.

[0068] When the bending is completed, the operator rotates the shift roller 201 in the reverse direction to reset it, and when the notch 3011 on the disc 301 corresponds to the pressure plate 302, the compressed compression spring 3024 drives the pressure plate 302 to move upward, and the pressure plate 302 moves upward to complete the unlocking operation, and the pressure plate 302 can also drive the L-shaped bracket 3031 to move upward, and the L-shaped bracket 3031 drives the synchronization plate 303 and the top block 3032, and the top block 3032 is ejected in the first bending groove 1022, so as to facilitate the separation of the pin and the first bending groove 1022.
