Description

Technical Field

[0001] The present application relates to the field of semiconductor processing technology, and in particular to a semiconductor cutting and forming device. Background Art

[0002] In the field of semiconductor manufacturing, with the rapid development of miniaturization and high performance of electronic products, the production efficiency and precision requirements of semiconductor devices are becoming more and more stringent. Traditional processes usually use a simple matrix layout for the layout of semiconductors on the processing board. The semiconductors that seem to be neatly arranged lack effective guidance and positioning structures. During the processing, especially after the connection between the semiconductor and the processing board is cut off, the semiconductor is very likely to shift in position. This not only destroys the continuity of the processing, making the subsequent processes poorly connected and greatly reducing production efficiency, but also causes the dimensional accuracy of subsequent punching and bending operations to be out of control due to the uncertainty of position, thus affecting the production quality of the product. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a semiconductor cutting and forming device, which can improve the processing accuracy and processing efficiency of the product.

[0004] The present application provides a semiconductor cutting and forming device, comprising:

[0005] A straight conveyor line, wherein a plurality of processing plates are placed on the straight conveyor line, wherein the processing plates include a plurality of processing windows, wherein the length direction of the processing windows is consistent with the conveying direction of the straight conveyor line, wherein a plurality of semiconductors arranged along the conveying direction of the straight conveyor line are arranged in the processing windows; wherein the semiconductors include injection-molded shells and lead frames, wherein the lead frames extend from both sides of the injection-molded shells and are connected to both side edges of the processing windows, wherein the injection-molded shells of adjacent semiconductors are connected via a first connector, and wherein the injection-molded shells of the semiconductors near the end of the processing window are connected to the end edge of the processing window via the first connector;

[0006] A first punching device, which is arranged beside the linear conveyor line and is used to sequentially cut off all the first connectors and the connection between the lead frame and the processing window on one side of the injection-molded housing;

[0007] A punching and bending device, which is arranged beside the linear conveyor line and is located at the rear side of the first punching device along the conveying direction of the linear conveyor line, and is used to sequentially cut off the connection between the lead frame on the other side of the injection molded shell and the processing window, and bend the lead frames on both sides of the injection molded shell;

[0008] The material receiving device is arranged at the rear end of the punching and bending device along the conveying direction of the straight conveying line, and is used to receive the semiconductor that has completed cutting and forming.

[0009] According to the semiconductor rib cutting and forming equipment of the embodiment of the present application, at least the following beneficial effects are achieved: in the present application, the unique processing window design on the processing board becomes the key layout basis of the entire process, the length direction of the processing window is consistent with the conveying direction of the straight conveyor line, and the semiconductors are neatly arranged in the window along this direction, and the semiconductors include an injection molded shell and a lead frame, the lead frame extends from both sides of the injection molded shell and is connected to the edges of both sides of the processing window, the injection molded shells of adjacent semiconductors are connected by a first connector, and the injection molded shell of the semiconductor near the end of the processing window is connected to the end edge of the processing window by the first connector. During production, the straight conveyor line is started, and the tray with several processing boards placed thereon is smoothly conveyed forward, and when the processing board moves to the bottom of the first punching device, the first punching device sequentially cuts off all the first connectors, as well as the connection between the lead frame on one side of the injection molded shell and the processing window, and since the semiconductor is confined within the processing window, there will be no positional offset during the punching process, thereby ensuring a high-precision punching effect. Next, the processing plate continues to move along the straight conveyor line and arrives at the punching and bending device. The punching and bending device first cuts off the connection between the lead frame on the other side of the injection molding shell and the processing window.

Then the punching and bending device bends the lead frames on both sides of the injection molding shell. The precise positioning of the processing window on the semiconductor greatly guarantees the dimensional accuracy of the punching, bending and other processes. At the same time, due to the role of the processing window, there is no need to reposition during punching and bending, which improves the processing efficiency of the product.

[0033] In the field of semiconductor manufacturing, with the rapid development of miniaturization and high performance of electronic products, the production efficiency and precision requirements of semiconductor devices are becoming more and more stringent. Traditional processes usually use a simple matrix layout for the layout of semiconductors on the processing board. The semiconductors that seem to be neatly arranged lack effective guidance and positioning structures. During the processing, especially after the connection between the semiconductor and the processing board is cut off, the semiconductor is very likely to shift in position. This not only destroys the continuity of the processing, making the subsequent processes poorly connected and greatly reducing production efficiency, but also causes the dimensional accuracy of subsequent punching and bending operations to be out of control due to the uncertainty of position, thus affecting the production quality of the product.

[0034] Reference Figures 1 to 5The present application provides a semiconductor rib cutting and forming device, comprising: a straight conveyor line 100, a first punching device 200, a punching and bending device 300 and a material receiving device 400, a plurality of processing plates 700 are placed on the straight conveyor line 100, the processing plates 700 include a plurality of processing windows 710, the length direction of the processing windows 710 is consistent with the conveying direction of the straight conveyor line 100, and a plurality of semiconductors arranged along the conveying direction of the straight conveyor line 100 are arranged in the processing windows 710; the semiconductor includes an injection molded shell 721 and a lead frame 722, the lead frame 722 extends from both sides of the injection molded shell 721 and is connected to the edges of both sides of the processing window 710, the injection molded shells 721 of adjacent semiconductors are connected by a first connecting piece 723, and the injection molded shells of the semiconductors near the ends of the processing windows 710 are connected to the edges of the processing windows 710. 721 is connected to the end edge of the processing window 710 through the first connecting piece 723; the first punching device 200 is arranged on the side of the straight conveyor line 100, and is used to sequentially cut off all the first connecting pieces 723, and the connection between the lead frame 722 on one side of the injection molding shell 721 and the processing window 710; the punching and bending device 300 is arranged on the side of the straight conveyor line 100, and is located at the rear side of the first punching device 200 along the conveying direction of the straight conveyor line 100, and is used to sequentially cut off the connection between the lead frame 722 on the other side of the injection molding shell 721 and the processing window 710, and bend the lead frame 722 on both sides of the injection molding shell 721; the receiving device 400 is arranged at the rear end of the punching and bending device 300 along the conveying direction of the straight conveyor line 100, and is used to receive the semiconductors that have completed the cutting and forming.

[0035] In the present application, the unique processing window 710 design on the processing plate 700 becomes the key layout basis of the entire process. The length direction of the processing window 710 is consistent with the conveying direction of the straight conveyor line 100, and the semiconductors are neatly arranged in the window along this direction. The semiconductor includes an injection molded shell 721 and a lead frame 722. The lead frame 722 extends from both sides of the injection molded shell 721 and is connected to the two side edges of the processing window 710. The injection molded shells 721 of adjacent semiconductors are connected by a first connector 723. The injection molded shell 721 of the semiconductor near the end of the processing window 710 is connected to the end edge of the processing window 710 through the first connector 723. During production, the straight conveyor line 100 is started, and the tray with several processing plates 700 is smoothly conveyed forward. When the processing plate 700 moves to the bottom of the first punching device 200, the first punching device 200 sequentially cuts off all the first connectors 723 and the connection between the lead frame 722 on one side of the injection molded shell 721 and the processing window 710. Since the semiconductor is confined in the processing window 710, there will be no positional offset during the punching process, ensuring a high-precision punching effect. Then, the processing plate 700 continues to move along the straight conveyor line 100 and arrives at the punching and bending device 300. The punching and bending device 300 first cuts off the connection between the lead frame 722 on the other side of the injection molded shell 721 and the processing window 710. At this time, although the semiconductor no longer has a direct connection with the processing plate 700, because the semiconductor is still in the processing window 710, the end of the processing window 710 pushes the semiconductor inside to move, ensuring that the semiconductor can move with the processing window 710 in an orderly manner, ensuring that it enters the bending process smoothly. Then, the punching and bending device 300 bends the lead frame 722 on both sides of the injection molded shell 721. The precise positioning of the semiconductor by the processing window 710 greatly ensures the dimensional accuracy of the punching, bending and other processes. At the same time, due to the function of the processing window 710, there is no need to reposition during punching and bending, thereby improving the processing efficiency of the product. Finally, the semiconductor that has completed the cutting and forming is moved to the position of the material receiving device 400 along with the processing plate 700, and the finished semiconductor will naturally fall into the material receiving device 400, thereby completing the entire production process. In addition, the present application also adopts the method of a straight conveyor line 100 to avoid processing pauses and position adjustments caused by turning and transferring, greatly shortening the processing time of each semiconductor and improving the overall processing efficiency.

[0036] Reference Figure 1 and Figure 2It can be understood that the linear conveyor line 100 includes two linear guides 110 and a plurality of transmission wheels 120, the spacing between the two linear guides 110 is less than the width of the processing board 700, and the plurality of transmission wheels 120 are arranged at intervals on one of the linear guides 110, and the spacing between two adjacent transmission wheels 120 is less than the length of the processing board 700. The spacing between the two linear guides 110 is less than the width of the processing board 700, so that the processing board 700 can be placed stably on the linear guides 110. At the same time, transmission wheels 120 are arranged at intervals at the linear guides 110 on one side, and the spacing between two adjacent transmission wheels 120 is less than the length of the processing board 700, so as to ensure that at any time, at least one transmission wheel 120 contacts the processing board 700 and provides power, so as to ensure that the processing board 700 can obtain power continuously and stably without power interruption, and at the same time, the transmission wheel 120 acts on the top of the processing board 700, and can also play a role in pressing the processing board 700. It should be noted that the distance between the two linear guide rails 110 is adjustable, and the position of each transmission wheel 120 on the linear guide rail 110 is also adjustable, so as to adapt to processing plates 700 of different sizes.

[0037] Reference Figure 5 It can be understood that the first punching device 200 includes a first punching die head 210. The bottom of the first punching die head 210 is provided with at least a first cutting head and a second cutting head in sequence along the conveying direction of the straight conveyor line. The first cutting head is used to cut off all the first connecting members 723, and the second cutting head is used to cut off the connection between the lead frame 722 on one side of the injection-molded shell 721 and the processing window 710. The first cutting head and the second cutting head provided at the bottom of the first punching die head 210 are arranged in sequence according to the conveying direction. First, the first cutting head cuts off all the first connecting members 723 to separate the injection-molded shells 721 of adjacent semiconductors, and then the second cutting head immediately cuts off the connection between the lead frame 722 on one side of the injection-molded shell 721 and the processing window 710. This integrated design reduces the number of equipment actions and processing time during the processing, and improves production efficiency. In addition, although there is a hollow area between the two linear guide rails 110, the punching range of the first punching device 200 is the connection between all the first connecting parts 723 and the lead frame 722 on one side of the injection molded shell 721 and the processing window 710, and the lead frame 722 on the other side of the semiconductor is still connected to the processing window 710. Therefore, the semiconductor will not fall from the hollow part between the two linear guide rails 110 after the processing plate 700 passes through the first punching device 200.

[0038] Reference Figure 5It can be understood that the punching and bending device 300 includes a punching and bending die 320 and a bottom plate 310. The bottom plate 310 is located below the two linear guide rails 110, and the punching and bending die 320 is located above the bottom plate 310. The punching and bending die 320 is used to sequentially cut off the connection between the lead frame 722 on the other side of the injection molding shell 721 and the processing window 710, and bend the lead frames 722 on both sides of the injection molding shell 721. The bottom plate 310 is used to support the semiconductor dropped from the processing plate 700, and the upper surface of the dropped semiconductor is higher than the position of the processing window 710, so that with the transmission of the linear conveyor line 100, the end of the processing window 710 can push the semiconductor to move. The punching and bending die 320 can sequentially complete the operation of cutting off the connection between the lead frame 722 on the other side of the injection molding shell 721 and the processing window 710 and bending the lead frame 722 in the same device, reducing the number of equipment and the conversion time between processing steps, and greatly improving production efficiency. At the same time, the bottom plate 310 is located below the two linear guide rails 110. When the punching and bending device 300 is working, the semiconductor will fall onto the bottom plate 310 after cutting off the last connection with the processing plate 700. The existence of the bottom plate 310 prevents the semiconductor from falling directly on the ground or other equipment parts and causing damage, and also facilitates the subsequent bending process. In addition, the upper surface of the fallen semiconductor is higher than the position of the processing window 710, so that the semiconductor can maintain contact with the end of the processing window 710 on the bottom plate 310. When the linear conveyor line 100 continues to transmit, the end of the processing window 710 can push the semiconductor to move. Through the support of the bottom plate 310 and the push of the end of the processing window 710, the subsequent bending process continues in an orderly manner, ensuring the continuity of the processing flow and the stability of the semiconductor position.

[0039] Reference Figures 3 to 5It can be understood that the bottom of the punching and bending die 320 is provided with a third cutting head and several bending heads in sequence along the conveying direction of the straight conveyor line 100. The third cutting head is used to cut off the connection between the lead frame 722 on the other side of the injection molding shell 721 and the processing window 710. The several bending heads are used to bend the lead frames 722 on both sides of the injection molding shell 721 to different degrees. The bottom plate 310 is provided with avoidance grooves at the cutting position of the third cutting head and the bending position of the bending head. The bottom plate 310 is provided with avoidance grooves at the cutting position of the third cutting head and the bending position of the bending head, which can avoid interference between the punching and bending die 320 and the bottom plate 310. Among them, there are multiple bending heads, each bending head is used to bend the lead frame 722 on both sides of the injection molded shell 721 to different degrees. For example, if a precise 180-degree bending of the lead frame 722 is to be achieved, the first bending head is installed at the front end of the punching and bending die 320 close to the third cutting head. When the semiconductor is pushed under the punching and bending device 300 and the third cutting head completes the cutting of the connection between the lead frame 722 on the other side of the injection molded shell 721 and the processing window 710, the first bending head bends the lead frame 722 from the initial horizontal state to 40 degrees. After the first bending head completes the action, the second bending head further bends the lead frame 722 that has been bent 40 degrees to 90 degrees. At this time, the lead frame 722 presents a right angle state. Then, the third bending head bends the lead frame 722 at 90 degrees by another 45 degrees to 135 degrees. Finally, the fourth bending head, as the finishing step, accurately bends the lead frame 722 at 135 degrees to 180 degrees, completing the molding of the entire lead frame 722. During the entire process, the four bending heads work closely together in sequence, and according to the conveying speed of the semiconductor, the precise positioning of the processing window 710, and the preset bending program, the lead frame 722 is gradually bent to the ideal 180 degrees in an orderly manner, realizing an efficient and high-precision processing process.

[0040] Reference Figure 6It can be understood that before punching, the distance between the punching and bending die 320 and the bottom plate 310 is a first spacing, the first spacing is greater than the height of the semiconductor before bending, and the first spacing is less than twice the height of the semiconductor before bending. Since the processing plate 700 needs to pass between the punching and bending die 320 and the bottom plate 310, the first spacing is set to be greater than the height of the semiconductor before bending, which reserves sufficient space for the movement of the processing plate 700, so that it can move along the straight conveyor line 100 without hindrance, avoiding scratches, collisions, etc. between the processing plate 700 and the punching and bending die 320 or the bottom plate 310, thereby ensuring the continuity of the entire processing flow. At the same time, when passing through the punching and bending die 320, the connection between the lead frame 722 on the other side of the injection molding shell 721 and the processing window 710 will be cut off first. After the cutting is completed, there is no direct connection between the semiconductor and the processing plate 700, that is, the semiconductor is mainly supported by the base plate 310, and the movement of the semiconductor requires the processing window 710 on the processing plate 700 to push it to move. During the pushing process of the processing window 710, some semiconductors may be stacked together. Therefore, the first spacing between the punching and bending die 320 and the base plate 310 is less than twice the height of the semiconductor before bending. When the processing window 710 pushes the semiconductor, the semiconductor will not get out of control due to too loose space, thereby effectively preventing the stacking of semiconductors, ensuring that each semiconductor can enter the subsequent bending process in an orderly state under the guidance of the processing window 710, maintaining the efficiency and accuracy of the processing process.

[0041] Reference Figure 1 and Figure 5 It can be understood that the receiving device 400 is arranged at the rear end of the bottom plate 310 along the conveying direction of the straight conveyor line 100, and is used to receive the bent semiconductors dropped from the bottom plate 310. After the semiconductors are bent at the punching and bending device 300, they can directly fall into the receiving device 400, avoiding manual handling or additional transfer links, greatly improving production efficiency, and ensuring the continuity and smoothness of production.

[0042] Reference Figure 5It can be understood that the semiconductor cutting and forming equipment provided by the present application also includes a first image recognition module 510 and a first material picking module 520. The length of the base plate 310 is greater than the length of the punching and bending die 320. The first image recognition module 510 and the first material picking module 520 are arranged on the rear side of the punching and bending die along the conveying direction of the straight conveyor line 100, and are located above the base plate 310; the first image recognition module 510 is used to collect the first image information of the semiconductor transmitted from the punching and bending die, and the first material picking module 520 is used to remove the semiconductors that do not meet the standards transmitted from the punching and bending die according to the first image information. The first image recognition module 510 can collect the first image information of the semiconductor transmitted from the punching and bending die head, and determine whether the punching of the semiconductor in the previous process is qualified and whether the bending is in place by performing image recognition on the first image information. The first material picking module 520 can accurately remove substandard semiconductors from the final product flow based on the information provided by the first image recognition module 510, thereby preventing defective products from mixing into qualified products and ensuring the quality stability of the delivered products.

[0043] Reference Figure 1 , Figure 2 and Figure 5 It can be understood that the semiconductor rib cutting and molding equipment provided by the present application further includes a loading device 600, which is arranged beside the linear conveyor line 100 and located in front of the first punching device 200 along the conveying direction of the linear conveyor line 100, and is used to transfer the processing board 700 that has completed lead welding and plastic sealing to the linear conveyor line 100. The loading device 600 is located beside the linear conveyor line 100 and before the first punching device 200. It can automatically transfer the processing board 700 that has completed lead welding and plastic sealing to the linear conveyor line 100, making the production process of the entire semiconductor rib cutting and molding equipment more coherent, avoiding the time delay and position error that may be caused by manual handling of the processing board 700, and effectively improving the production efficiency.

[0044] It can be understood that the feeding device 600 includes a second image recognition module and a second material taking module, the second material taking module is used to grab the processing board 700 that has completed lead welding and plastic sealing, the second image recognition module is used to collect the second image information of the processing board 700 grabbed by the second material taking module, and the second material taking module is also used to correct the grabbed processing board 700 according to the second image information and transfer it to the linear conveyor line 100. By collecting the second image information of the processing board 700, the second material taking module can detect the position deviation of the processing board 700, and then perform precise correction operations to ensure that the processing board 700 is transferred to the linear conveyor line 100 in the correct posture and position, providing a precise starting position for the subsequent first punching device 200 and other processing links, thereby improving the accuracy of the entire processing flow.

[0045] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
