[0001] The present application relates to the technical field of electronic packaging, and particularly relates to a material grabbing mechanism, a blanking device and a blanking system. Background Art

[0002] In the field of electronic packaging, the blanking system is responsible for transferring the lead frame that has completed WB (Wire Bonding) from one link in the production process to the next. As an important part of electronic devices, the transmission effect of the lead frame in automated equipment directly affects the quality of the final product.

[0003] During the transmission of the lead frame, the material grabbing mechanism in the blanking system grabs the storage bin so that the storage bin receives the transmitted lead frame at an appropriate position. In practice, the inventor found that the existing material grabbing mechanism has the following defects: the lead frame may be deformed or damaged due to the uneven level between devices during the transmission process, that is, the lead frame collides with the storage bin during the process of entering the storage bin, which not only increases the scrap rate of the product but also affects the production efficiency. Summary of the Utility Model

[0004] The purpose of the present application is to provide a material grabbing mechanism, which realizes precise control and detection of the clamping posture of the storage bin through an integrated base, clamping seat and positioning component, effectively avoiding deformation or damage of the lead frame during transmission caused by incorrect clamping of the storage bin, and improving the production efficiency and product yield. Another purpose of the present application is to provide a blanking device and a blanking system.

[0005] To achieve the above purpose, the present application provides a material grabbing mechanism, including:

[0006] A base, the base is provided with a driving member;

[0007] A clamping seat, the clamping seat is connected to the driving member, and the clamping seat is used to clamp the storage bin together with the base. The surfaces of the storage bin that are clamped are the upper and lower surfaces, and a surface to be detected is connected between the upper and lower surfaces;

[0008] A positioning component, the positioning component is installed on the base, the positioning component is arranged towards the surface to be detected, and the positioning component is used to detect the surface to be detected when the storage bin is clamped to judge whether the clamping posture of the storage bin is correct.

[0009] In some embodiments, the positioning component includes:

[0010] A positioning member, the positioning member is used to contact the surface to be detected so that the surface to be detected and the storage bin are in a vertical state;

[0011] A detector for detecting a surface to be detected to determine whether the positioning member is in correct contact with the surface to be detected.

[0012] In some embodiments, the detector is a contact sensor.

[0013] In some embodiments, the contact sensor is arranged at the same height as the positioning member.

[0014] In some embodiments, the positioning member and the detector are coaxially arranged.

[0015] In some embodiments, the positioning member and the detector are arranged side by side.

[0016] In some embodiments, the positioning assembly further includes:

[0017] A cross beam arranged on the base;

[0018] A pair of connecting blocks arranged at both ends of the cross beam, and the positioning member and the detector are arranged on each of the connecting blocks.

[0019] In some embodiments, the connecting block is provided with an adjustment hole for assembling the detector, and the position of the detector can be adjusted through the adjustment hole. The connecting block is further provided with an adjustment member for locking the position of the detector in the adjustment hole.

[0020] The present application also provides a blanking device, including a driving mechanism and the above-mentioned material grabbing mechanism. The driving mechanism is connected to the material grabbing mechanism, and the driving mechanism is used to control the movement of the material grabbing mechanism in space.

[0021] The present application also provides a blanking system, including a conveying mechanism and the above-mentioned blanking device. The conveying mechanism is used to convey a storage bin, and the storage bin is clamped by the blanking device to make the storage surface of the storage bin parallel to the conveying surface of the conveying mechanism.

[0022] Compared with the above background technology, the material grabbing mechanism provided by the present application mainly includes a base, a clamping seat and a positioning assembly. The base is provided with a driving member; the clamping seat is connected to the driving member, and the clamping seat is used to clamp the storage bin together with the base. The clamped surfaces of the storage bin are the upper and lower surfaces, and a surface to be detected is connected between the upper and lower surfaces; the positioning assembly is installed on the base and is arranged towards the surface to be detected.

During this period, the driving member works, driving the clamping seat to move towards the base, and then the storage bin is clamped together with the base by the clamping seat. It should be noted that when the storage bin is correctly clamped by the material grabbing mechanism, the storage surface in the storage bin will be parallel to the conveying surface of the conveying mechanism for conveying the lead frame, so that the lead frame can smoothly enter the storage bin; however, there is still a situation where the traditional material grabbing mechanism is not clamped correctly. At this time, when the storage bin is not correctly clamped, it will cause damage to the lead frame due to interference and collision when the lead frame enters the storage bin. In view of this, the material grabbing mechanism provided in this application is specifically provided with a positioning component with a detection function, which can ensure that the storage bin is correctly clamped. During this period, when the storage bin is clamped, the positioning component detects and confirms whether the storage bin is in the correct clamping posture by detecting the position of the surface to be detected, such as contact detection or distance detection. When the storage bin is correctly clamped, the transmission and storage of the lead frame can continue.

[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Please refer to Figure 1 and Figure 2 , where Figure 1 is the structural diagram of the material grasping mechanism provided by the embodiment of the present application, Figure 2 is the structural diagram of the blanking system provided by the embodiment of the present application.

[0040] In the first specific embodiment, the material grasping mechanism 100 provided by the embodiment of the present application mainly includes a base 101, a clamping seat 102 and a positioning assembly 200. The base 101 is provided with a driving member 103; the clamping seat 102 is connected to the driving member 103. The clamping seat 102 is used to clamp the storage bin 01 together with the base 101. The clamped surfaces of the storage bin 01 are the upper and lower surfaces, and a surface to be detected is connected between the upper and lower surfaces; the positioning assembly 200 is installed on the base 101, the positioning assembly 200 faces the surface to be detected, and the positioning assembly 200 is used to detect the surface to be detected when the storage bin 01 is clamped, so as to judge whether the clamping posture of the storage bin 01 is correct.

[0041] During the process of using the material grasping mechanism 100, the material grasping mechanism 100 performs the clamping work on the storage bin 01. During this period, the driving member 103 works, driving the clamping seat 102 to move towards the direction close to the base 101, and then the storage bin 01 is clamped together by the clamping seat 102 and the base 101. It should be noted that when the storage bin 01 is correctly clamped by the material grasping mechanism 100, the storage surface 0101 in the storage bin 01 will be in a parallel state with the conveying surface 0301 of the conveying mechanism 03 for conveying the lead frame 02, so that the lead frame 02 can smoothly enter the storage bin 01; however, there is still a situation where the traditional material grasping mechanism is not clamped correctly. At this time, when the storage bin 01 is not correctly clamped, it will cause the problem that the lead frame 02 is damaged due to interference and collision when entering the storage bin 01. In view of this, the material grasping mechanism 100 provided in this application is specially provided with a positioning component 200 with a detection function, which can ensure that the storage bin 01 is correctly clamped. During this period, when the storage bin 01 is clamped, the positioning component 200 detects and confirms whether the storage bin 01 is in the correct clamping posture by detecting the position of the surface to be detected, such as contact detection or distance detection. When the storage bin 01 is correctly clamped, the transmission and storage of the lead frame 02 can continue. When the storage bin 01 is not clamped correctly, a warning signal can be output and the operation can be stopped for maintenance.

[0042] Combined with the above structure and process description, it can be seen that the material grasping mechanism 100 has at least the following beneficial effects: the material grasping mechanism 100 realizes the precise control and detection of the clamping posture of the storage bin 01 through the integrated base 101, clamping seat 102 and positioning component 200, effectively avoiding the deformation or damage of the lead frame 02 during the transmission process caused by the incorrect clamping of the storage bin 01, and improving the production efficiency and product yield.

[0043] It should be noted that the specific detection principle of the positioning component 200 is not limited in this embodiment. For example, the positioning component 200 can adopt the contact detection method, and judge whether the storage bin 01 is correctly clamped by detecting whether the positioning component 200 is in contact with the surface to be detected. In addition, the positioning component 200 can also adopt the distance detection method, and judge whether the storage bin 01 is correctly clamped by detecting whether the distance between the positioning component 200 and the surface to be detected meets the requirements. The above different detection methods should all fall within the scope of the description of this embodiment.

[0044] Please refer to Figure 3 , Figure 3 which is the structural diagram of the positioning component provided by the embodiment of this application.

[0045] In some embodiments, the positioning component 200 includes a positioning member 205 and a detector 206.

[0046] In this embodiment, the positioning component 200 not only improves the accuracy of clamping the storage bin 01 but also enhances the reliability and efficiency of the entire material grabbing mechanism 100.

[0047] The positioning member 205 is a key part of the material grabbing mechanism 100, and it is responsible for ensuring the posture correction of the storage bin 01 under accurate clamping. The function of the positioning member 205 is to contact the surface to be detected of the storage bin 01, and this contact ensures that the surface to be detected remains vertical with the storage bin 01, which is a prerequisite for realizing precise clamping and transporting the lead frame 02. As an additional effect, through the acting force applied by the positioning member 205, the possibility of the storage bin 01 tilting or shifting during transportation can be reduced, thereby avoiding collisions or damages to the lead frame 02 during the storage process.

[0048] The detector 206 is used to detect the contact situation between the positioning member 205 and the surface to be detected. Its function is to monitor whether the positioning member 205 correctly contacts the surface to be detected, so as to confirm whether the storage bin 01 is in the correct clamping posture. If the detector 206 detects that there is no correct contact between the positioning member 205 and the surface to be detected, it can trigger a warning signal or stop the machine to prevent possible damages or production interruptions.

[0049] Among them, the detector 206 also has different setting forms according to different detection methods of the positioning component 200, including but not limited to contact sensors such as capacitive and photoelectric, or distance sensors such as laser and infrared, etc., which also belong to the scope of description of this embodiment.

[0050] In some embodiments, the detector 206 is a contact sensor.

[0051] In this embodiment, the contact sensor can detect the presence of an object through physical contact. The contact sensor usually includes a triggering mechanism. When an object touches the surface of the sensor, an electrical signal will be triggered, thereby realizing the detection of the object's position. This type of sensor is suitable for application scenarios that require high-precision position confirmation. For example, in the material grabbing mechanism, it ensures that the storage bin 01 is correctly clamped and in the desired vertical state. The working principle of the contact sensor is simple and direct, and it can provide reliable performance in various industrial environments. By using the contact sensor, the material grabbing mechanism can achieve precise control of the clamping posture of the storage bin 01, thereby improving the efficiency and reliability of the entire automated production line.

[0052] In some embodiments, the contact sensor 206 is set at the same height as the positioning member 205.

[0053] In this embodiment, the contact sensor 206 is designed to be at the same height as the positioning member 205. This configuration allows the two to contact the surface to be detected simultaneously. This equal-height setting can ensure that when clamping the storage bin 01, the positioning member 205 and the contact sensor 206 can work together to provide accurate detection and positioning. In other words, when the positioning member 205 contacts the surface to be detected, by setting the contact sensor 206, it can be further determined whether the positioning member 205 is in correct contact with the surface to be detected.

[0054] Therefore, when the storage bin 01 is clamped by the clamping seat 102 and the base 101, the positioning member 205 contacts the surface to be detected to ensure its vertical state, while the contact sensor 206 detects whether such contact occurs, thereby verifying whether the clamping posture of the storage bin 01 is correct.

[0055] In some embodiments, the positioning member 205 and the detector 206 are coaxially arranged.

[0056] In this embodiment, the positioning member 205 and the detector 206 are coaxially arranged, which means they share the same axis. This layout allows the detector 206 to directly sense the contact when the positioning member 205 contacts the surface to be detected. The advantage of the coaxial arrangement is that it can ensure that the detector 206 makes an accurate response to the position change of the positioning member 205, thereby improving the accuracy and reliability of the detection.

[0057] Optionally, a notch is formed on the positioning member 205, the detector 206 is installed in the notch, and the end of the contact sensor 206 is arranged at the same height as the end of the positioning member 205.

[0058] In addition to this embodiment, in some embodiments, the positioning member 205 and the detector 206 are arranged side by side, as Figure 3 shown. The advantage of this is that the cost can be reduced.

[0059] Please continue to refer to Figure 3 , in some embodiments, the positioning assembly 200 further includes a cross beam 201 and a pair of connecting blocks 202.

[0060] In this embodiment, the cross beam 201 is a key part of the positioning assembly 200 and is fixed to the base 101. To ensure that the cross beam 201 can be accurately positioned on the base 101, it is installed through the mounting holes 203 and the mounting parts 204. The mounting holes 203 are preset hole positions on the base 101, and the number can be multiple to facilitate adjusting the mounting position of the cross beam 201 on the base 101, while the mounting parts 204 such as screws, bolts or buckles are used to fix the cross beam 201 at the required appropriate position.

[0061] A pair of connecting blocks 202 are installed at both ends of the cross beam 201. Such a layout not only provides structural stability but also allows for fine adjustment of the positioning assembly 200. A positioning member 205 and a detector 206 are integrated on each connecting block 202. At this time, the positioning members 205 and detectors 206 at both ends of the cross beam 201 perform positioning and detection in contact simultaneously.

[0062] Optionally, as Figure 3 shown, the positioning member 205 is designed as a columnar structure, and its end face serves for contact and positioning with the surface to be detected. The detector 206 can be designed as a structure similar to the positioning member 205. The detector 206 not only has the contact and positioning function of the positioning member 205 but also has a contact judgment function.

[0063] In some embodiments, the connecting block 202 is provided with an adjustment hole 207 for assembling the detector 206, and the detector 206 can adjust its position through the adjustment hole 207. The connecting block 202 is also provided with an adjusting member 208 for locking the position of the detector 206 in the adjustment hole 207.

[0064] In this embodiment, the design of the connecting block 202 is further optimized to provide more flexible adjustment capabilities. The connecting block 202 is provided with adjustment holes 207, which are specifically used for assembling the detector 206. Through the adjustment holes 207, the detector 206 can move along the hole positions, thereby adjusting its position on the connecting block 202 to adapt to the surfaces to be detected at different positions.

[0065] To ensure that the detector 206 can be stably fixed after being adjusted to the appropriate position, the connecting block 202 is also equipped with an adjusting member 208. The function of the adjusting member 208 is to lock the detector 206 at a specific position in the adjustment hole 207 to prevent displacement or vibration during operation. This locking mechanism is usually realized by nuts, clamps or other forms of fasteners.

[0066] This application also provides a blanking device, including a driving mechanism and the above-mentioned material grabbing mechanism 100. The driving mechanism is connected to the material grabbing mechanism 100, and the driving mechanism is used to control the movement of the material grabbing mechanism 100 in space.

[0067] In this embodiment, the driving mechanism can have displacement capabilities in multiple directions, such as longitudinally and vertically. Through the longitudinal movement of the driving mechanism, the material grabbing mechanism 100 can be controlled to move forward relative to the storage bin 01 to the outside of the storage bin 01, and then move backward to the longitudinally specified position after clamping the storage bin 01. Through the vertical movement of the driving mechanism, the material grabbing mechanism 100 can be controlled to drive the clamped storage bin 01 to move to the vertically specified position, so as to realize the blanking operation of the blanking device for the storage bin 01 and the lead frame 02 therein.

[0068] Please continue to refer to Figure 2 , this application also provides a blanking system, including a conveying mechanism 03 and the above-mentioned blanking device. The conveying mechanism 03 is used to convey the storage bin 01, and the storage bin 01 is clamped by the blanking device to make the storage surface 0101 of the storage bin 01 parallel to the conveying surface 0301 of the conveying mechanism 03.

[0069] As Figure 2 shown, the x-axis in the figure corresponds to the longitudinal direction, the y-axis corresponds to the transverse direction, and the z-axis corresponds to the vertical direction. The conveying mechanism 03 can adopt a stepping control mode, and the specific structural form is not limited here. The lead frame 02 is conveyed backward along the longitudinal direction by the conveying mechanism 03. Behind the conveying mechanism 03, there is a storage bin 01 for preparing to store the lead frame 02. The storage bin 01 is clamped by the grasping mechanism 100 in the blanking device. Since the positioning component 200 in the grasping mechanism 100 can position and detect the storage bin 01, the problem of the storage bin 01 tilting in the y direction is prevented, ensuring that the conveying surface 0301 is parallel to the storage surface 0101, that is, ensuring the perpendicularity of the storage bin 01 relative to the conveying mechanism 03, thereby solving the problems of collision deformation and material jamming of the lead frame 02 caused by the storage bin 01 and the conveying mechanism 03 not being on the same horizontal line.

[0070] Please continue to refer to Figure 2 , in some cases, the storage bin 01 includes a top plate 011, a bottom plate 012 and side plates 013. The outer surfaces of the top plate 011 and the bottom plate 012 are the clamping surfaces of the storage bin 01, and the side plates 013 are connected between the top plate 011 and the bottom plate 012. The outer surface of the side plate 013 is the surface to be detected of the storage bin 01, wherein the side plate 013 is perpendicular to the top plate 011 and the bottom plate 012. In addition, a wire groove 0131 is provided on the inner surface of the side plate 013, and the lead frame 02 is stored in layers in the storage bin 01 along the z direction through the wire groove 0131.

[0071] It should be noted that many components mentioned in this application are common standard components or components known to those skilled in the art, and their structures and principles can be known by those skilled in the art through technical manuals or by conventional experimental methods.

[0072] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0073] The above has introduced in detail the material grasping mechanism, the material discharging device and the material discharging system provided by the present application.

The description of the above embodiments is only used to help understand the method and its core idea of the present application.
