Description

Technical Field

[0001] The present invention relates to the technical field of bent needle processing, and in particular to a special processing device for S-shaped bent needles used in IGBT modules. Background Art

[0002] IGBT modules are widely used in the field of power electronics. As one of the important components in IGBT modules, the processing quality of S-shaped bent needles will directly affect the performance and reliability of IGBT modules.

[0003] Currently, the processing method of S-shaped bent needles usually adopts flat stamping. The processing quality of this processing method is relatively stable, but the convenience of loading and unloading before and after stamping is relatively low. It is necessary for a manipulator to accurately place the needle parts flat on the stamping die or take them out from the stamping die. Due to the small volume of the needle parts and the limited operating space in the stamping processing area, the above-mentioned loading and unloading methods are difficult to quickly complete the picking and placing of the needle parts, occupying a long processing time, which will reduce the processing efficiency of the needle parts. Moreover, the difficulty of picking and placing the needle parts is relatively large, which is likely to reduce the stamping processing quality of the needle parts. Summary of the Invention

[0004] The present invention provides a special processing device for S-shaped bent needles used in IGBT modules to solve the problems in the related technologies, such as low convenience and high difficulty in loading and unloading before and after stamping, low overall processing efficiency, and easy reduction of processing quality.

[0005] The present invention provides a special processing device for S-shaped bent needles used in IGBT modules. The special processing device for S-shaped bent needles used in IGBT modules includes a feeding mechanism. The feeding mechanism includes a moving disk, a static disk coaxially arranged with the moving disk, and a feeding component installed on the moving disk and used for placing needle parts. The cap-shaped end and the processing part of the needle parts on the feeding component are in an exposed state. A loading station, a stamping station, and an unloading station are sequentially arranged along the circumferential direction of the moving disk. As the moving disk rotates, the feeding component sequentially passes through the above three stations. The feeding component includes a base elastically installed with a vertical moving seat. A profiling support head and an elastic clamping head are installed on the vertical moving seat. The elastic clamping head clamps and fixes the straight needle end of the needle part, and the profiling support head limits and supports the non-processing part of the needle part. A control component for controlling the opening of the elastic clamping head is installed on the static disk. A stamping mechanism is arranged at the stamping station. The stamping mechanism includes an upper die, a lower die, and a profiling protection head. The profiling protection head is installed on the upper die and moves with the upper die. After the feeding component enters the punching head station, the upper die moves downward. Before the upper die and the lower die are closed, the profiling protection head cooperates with the profiling support head to hold the non-processing part of the needle part and make the vertical moving seat move downward until the die is closed and formed.

[0006] In a possible implementation manner, the elastic clamping head includes symmetrically arranged profiling clamping blocks, an elastic member is connected between the profiling clamping blocks, a first limiting block is installed on the profiling clamping blocks, the control assembly includes a sliding seat provided with a pushing head, the sliding seats respectively correspond to the loading station and the unloading station one by one, and the pushing heads on the sliding seats correspond to the limiting blocks on the symmetric profiling clamping blocks one by one.

[0007] In a possible implementation manner, clamping and picking mechanisms are arranged on both the loading station and the unloading station. A loading mechanism is further arranged on the loading station, and a receiving box is further arranged on the unloading station. The clamping and picking mechanism on the loading station sends the needle parts from the loading mechanism to the feeding component in the loading station, and the clamping and picking mechanism in the unloading station sends the needle parts from the corresponding feeding component to the receiving box. Among them, the clamping and picking mechanism includes a clamping cylinder installed with clamping jaws, a displacement cylinder for controlling the up and down movement of the clamping cylinder, and a KK module for controlling the horizontal movement of the displacement cylinder.

[0008] In a possible implementation manner, the loading mechanism includes a circular vibrating bowl connected with a discharging track, a feeding support connected with a feeding block, and a material blocking block for limiting the needle parts. The needle parts automatically identify the direction in the circular vibrating bowl and then enter the discharging track and pass through the discharging track into the feeding block. After the needle parts enter the feeding block, they stop moving under the limitation of the material blocking block and wait to be picked up by the corresponding clamping and picking mechanism.

[0009] In a possible implementation manner, the profiling support head includes a support block provided with a first profiling groove, the profiling protection head includes an adjustment block provided with a second profiling groove and a limiting opening, the second profiling groove cooperates with the first profiling groove to hold the non-processing part of the needle part, and the limiting opening limits the support block.

[0010] In a possible implementation manner, the upper mold includes an upper mold base and an upper mold core, the upper mold core is detachably installed on the upper mold base, the lower mold includes a lower mold base and a lower mold core, and the lower mold core is detachably installed on the lower mold base.

[0011] In a possible implementation manner, a second limiting block is arranged between the symmetric profiling clamping blocks. Through the limitation of the second limiting block, the concentricity of the profiling clamping blocks in the clamping state is the same as that of the profiling support head.

[0012] In a possible implementation manner, the first limiting block is of a wheel-shaped structure and is rotatably installed on the profiling clamping block.

[0013] In a possible implementation manner, an arc-shaped protection head is installed on the lower mold. During the stamping process, the cap-shaped end of the needle part is located inside the arc-shaped protection head.

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5, A special processing equipment for S-shaped pins used in IGBT modules, including a feeding mechanism 1, a stamping mechanism 2 and a frame 6. The feeding mechanism 1 includes a moving disk 101, a static disk 102 concentrically arranged with the moving disk 101, and several feeding components 103 for placing needle parts. The feeding components 103 are evenly distributed along the circumferential direction of the moving disk 101. The static disk 102 is located inside the feeding components 103 and is fixedly installed on the frame 6. The moving disk 101 is of an annular structure and is rotatably installed on the frame 6. When the needle part is placed in the feeding component 103, its cap-shaped end and processing part are in an exposed state. A loading station, a stamping station and an unloading station are sequentially arranged along the circumferential direction of the moving disk 101. The feeding component 103 first passes through the loading station to pick up materials as the moving disk 101 rotates, then passes through the stamping station for stamping and forming processing, and finally passes through the unloading station to unload materials, and then repeats the above processing steps continuously to carry out the forming processing of the needle parts. And when any one of the feeding components 103 is located at the stamping station, corresponding feeding components 103 are parked at both the loading station and the unloading station. During the stamping process, the loading and unloading operations are completed simultaneously, separating the loading and unloading processes before and after stamping from the stamping processing process, increasing the operating space, facilitating loading and unloading and stamping processing. And when the needle part enters the stamping station, it is in a state of waiting for stamping processing and can be directly stamped. At the same time, during the stamping process, the non-stamped part of the needle part will be fixed and protected to prevent the needle part from undergoing unexpected deformation, effectively improving the efficiency of stamping processing and ensuring the processing quality as a whole.

[0029] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , the feeding component 103 includes a base 123 elastically installed with a vertical moving seat 113. The base 123 is fixedly installed on the moving disk 101. A profiling support head 133 and an elastic clamping head 143 are installed on the vertical moving seat 113. The profiling support head 133 is located outside the elastic clamping head 143, as Figure 4As shown, the elastic clamping head 143 clamps and fixes the straight needle end of the needle part, and the profiling support head 133 limits and supports the non-machined part of the needle part, so that the cap-shaped end and the machined part of the needle part are completely exposed, and directly enter the state to be stamped when entering the stamping station. After the processing is completed, it directly moves out of the stamping station with the rotation of the moving disk 101, effectively improving the convenience of loading and unloading materials before and after stamping and reducing the overall processing difficulty. Correspondingly, it is beneficial to improve the stamping processing efficiency and processing quality. A control component 104 for controlling the opening of the elastic clamping head 143 is installed on the static disk 102. When the feeding component 103 is located at the loading station or the unloading station, the elastic clamping head 143 is controlled to open through the control component 104 on the static disk 102, and correspondingly, the placement or removal of the needle part is completed, fully simplifying the structure of the components on the moving disk 101, so that the feeding component 103 on the moving disk 101 does not need to have a direct connection with the outside. Correspondingly, the moving disk 101 can rotate continuously and stably in the same direction, effectively reducing the complexity of the overall mechanical structure, and correspondingly improving the stability of the operation of the overall mechanical structure.

[0030] Refer to Figure 2 , Figure 7 , Figure 8 and Figure 9 , the stamping mechanism 2 includes an upper die 21, a lower die 22 and a profiling protection head 23. The lower die 22 is fixedly installed on the frame 6, the upper die 21 is vertically slidably installed on the frame 6, and the profiling protection head 23 is fixedly installed on the upper die 21. After the feeding component 103 enters the punch station, the upper die 21 is directly pressed down to close the die with the lower die 22 to complete the stamping process of the needle part. Among them, before the upper die 21 and the lower die 22 are closed, the profiling protection head 23 cooperates with the profiling support head 133 to hold the non-machined part of the needle part and make the vertical moving seat 113 move down until the die is closed and formed. The profiling protection head 23 and the profiling support head 133 cooperate to hold the non-machined part of the needle part, effectively avoiding the unexpected deformation of the needle part during the stamping process, improving the stamping processing efficiency and the quality of the needle part processing at the same time. Among them, when the profiling protection head 23 and the profiling support head 133 cooperate to hold the non-machined part of the needle part, there is a certain gap between them, which can freely expand and contract when the needle part is formed, ensuring that the concentricity remains unchanged when the needle part is formed, and at the same time, stress release can be obtained.

[0031] Refer to Figure 7 , Figure 8 and Figure 9 , an arc-shaped protection head 24 is fixedly installed on the lower die 22. The arc-shaped protection head 24 is a connecting block provided with an arc-shaped groove. The connecting block is fixedly connected to the lower die 22. During the stamping process, the cap-shaped end of the needle part is located in the arc-shaped groove, and the cap-shaped end of the needle part is supported and limited through the arc-shaped groove, which can effectively avoid the unexpected deformation of the needle part during the stamping process to a certain extent, and thus is beneficial to improving the stamping processing quality.

[0032] Refer to Figure 6 、 Figure 7 and Figure 8 As shown in, the profiling support head 133 includes a support block 1332 with a profiling groove 1331 formed on its top surface. The support block 1332 is fixedly installed on the vertical moving base 113. The profiling protection head 23 includes an adjusting block 233 provided with a profiling groove 231 and a limiting opening 232. The adjusting block 233 is fixedly installed on the upper die 21. The profiling groove 231 cooperates with the profiling groove 1331 to hold the non-machined part of the needle piece. The support block 1332 is inserted into the limiting opening 232, so that the profiling support head 133 and the profiling protection head 23 are stably connected together during the stamping process.

[0033] Refer to Figure 6 and Figure 7 As shown in, the upper die 21 includes an upper die base 211 and an upper die core 212. The upper die core 212 is detachably installed on the upper die base 211. The lower die 22 includes a lower die base 221 and a lower die core 222. The lower die core 222 is detachably installed on the lower die base 221. When it is necessary to machine Z-shaped needles and C-shaped needles, only the upper die core 212 and the lower die core 222 need to be replaced.

[0034] Refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in, the elastic clamping head 143 includes symmetrically arranged profiling clamping blocks 1431. An elastic member 1432 is connected between the symmetric profiling clamping blocks 1431. Under the action of the elastic member 1432, the symmetric profiling clamping blocks 1431 clamp and fix the needle piece. A first limiting block 1433 is installed on the top of the profiling clamping block 1431. The control component 104 includes a sliding seat 124 provided with a pushing head 114. The sliding seat 124 corresponds to the loading station and the unloading station respectively and is slidably installed on the static disk 102. The pushing head 114 on the sliding seat 124 corresponds to the first limiting block 1433 on the symmetric profiling clamping blocks 1431 one by one. As shown in Figure 5 shown, when the sliding seat 124 slides towards the feeding component 103 at the corresponding station, the pushing head 114 can limit the corresponding first limiting block 1433, so that the symmetric profiling clamping blocks 1431 open. Among them, the first limiting block 1433 is of a wheel-shaped structure and is rotatably installed on the profiling clamping block 1431, reducing the friction generated during the process of the pushing head 114 limiting the first limiting block 1433 and facilitating the control of the opening of the symmetric profiling clamping blocks 1431.

[0035] Refer to Figure 6 and Figure 7, a second limiting block 1434 is provided between the symmetric profiling clamping blocks 1431. Through the limitation of the second limiting block 1434, the concentricity of the profiling clamping blocks 1431 in the clamped state is made consistent with that of the profiling support head 133, improving the accuracy of the needle placement position.

[0036] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 10 , clamping and picking mechanisms 3 are provided on both the loading station and the unloading station. A loading mechanism 4 is also provided on the loading station, and a receiving box 5 is also provided on the unloading station. The clamping and picking mechanism 3 on the loading station sends the needle parts from the loading mechanism 4 to the feeding component 103 in the loading station, and the clamping and picking mechanism 3 in the unloading station sends the needle parts from the corresponding feeding component 103 to the receiving box 5. Among them, the clamping and picking mechanism 3 includes a clamping cylinder 32 equipped with a clamping jaw 31, a displacement cylinder 33 for controlling the up and down movement of the clamping cylinder 32, and a KK module 34 for controlling the horizontal movement of the displacement cylinder 33. The KK module 34 is a prior art for precisely controlling the linear movement of the displacement cylinder 33. The KK module 34 is installed on the frame 6. Taking the clamping and picking mechanism 3 on the loading station as an example, the clamping jaw 31 is controlled by the clamping cylinder 32 to pick up the needle parts on the loading mechanism 4, and then the displacement cylinder 33 controls the clamping cylinder 32 to move up to a preset position, so that the needle parts on the clamping jaw 31 are separated from the loading mechanism 4. Then, the KK module 34 controls the displacement cylinder 33 to move to the preset feeding position of the feeding component 103. After that, the displacement cylinder 33 controls the clamping cylinder 32 to move down to a preset position. At this time, the non-machined part of the needle part is located in the first profiling groove 1331 of the corresponding profiling support head 133, and the straight needle end of the needle part is located in the clamping area of the corresponding elastic clamping head 143. Then, the elastic clamping head 143 clamps the needle part. At this time, the needle part is in a stable placement state. Finally, the clamping cylinder 32 controls the clamping jaw 31 to loosen and reset for the next picking and feeding process.

[0037] Refer to Figure 2 and Figure 10 , the loading mechanism 4 includes a circular vibrating disk 42 connected to a discharging track 41, a feeding support 44 fixedly connected with a feeding block 43, and a stop block 45 for limiting the needle parts. The circular vibrating disk 42 is installed on the frame 6, and the feeding support 44 is fixedly installed on the frame 6. The needle parts automatically identify the direction in the circular vibrating disk 42 and then enter the discharging track 41. After coming out of the discharging track 41, they directly enter the feeding block 43 and stop moving under the block of the stop block 45. At this time, the clamping jaw 31 can pick up the needle parts.

[0038] In the embodiments of the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0039] In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, the terms "arranged", "connected", "installed" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection, or a sliding connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
