Description

Technical Field

[0001] This utility model relates to the field of power electronic component manufacturing technology, and in particular to a positioning device for power electronic component manufacturing. Background Technology

[0002] Power electronic components are high-power electronic devices used in the power conversion and control circuits of power equipment. In the production process of power electronic components, high-precision positioning is a key link to ensure the quality of processes such as welding and assembly.

[0003] Existing positioning devices can only position one component at a time, and cannot simultaneously position multiple components of the same specification. This results in only one component being processed at a time, leading to low processing efficiency. Furthermore, a single clamping point or rigid positioning structure can easily cause uneven force on the component, resulting in displacement during processing. This can lead to defects such as pin misalignment and cold solder joints in electronic components during the soldering process, affecting the soldering or assembly accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for the production of power electronic components, which solves the problem that the positioning device can only position one component at a time and cannot position multiple components of the same specification at the same time.

[0005] To address the existing technical problems, the technical solution of this utility model is as follows: A positioning device for the production of power electronic components includes a base. A support plate is fixedly connected to the inner cavity of the base. Two left and right clamping rods are slidably connected through the outer wall of the support plate. The two left and right clamping rods are driven by a clamping mechanism and can move synchronously in opposite directions. Multiple clamping plates are fixedly connected to the outer wall of each clamping rod. A clamping plate fixed on one clamping rod is slidably connected to another clamping rod. The clamping plates fixed on each clamping rod and the sliding clamping plates are spaced apart. The top of the clamping plate drives a positioning plate to move through a driving component. A positioning mechanism is symmetrically arranged between each pair of positioning plates to determine the center position of the component.

[0006] Preferably, the clamping mechanism includes a motor, which is fixedly connected to the bottom of the inner cavity of the base. The top end of the motor output shaft is fixedly connected to a gear via a coupling. One end of each clamping rod is fixedly connected to a rack, which meshes with the gear. The two racks are symmetrically located on both sides of the gear. A sliding plate is fixedly connected to the top of the rack. A sliding groove is provided at the top of the inner cavity of the base, and the inner wall of the sliding groove is slidably connected to the outer wall of the sliding plate.

[0007] Preferably, the driving component includes a driving block, the bottom of which is fixedly connected to the top of the clamping plate. The top of the base has a driving groove, the inner wall of which is fixedly connected to the top of the driving block. The top of the driving block is fixedly connected to the bottom of the positioning plate. The number of positioning plates corresponds to the number of clamping plates. There are multiple sets of positioning plates in pairs, and each set of positioning plates can move synchronously in opposite directions.

[0008] Preferably, the positioning mechanism includes a connecting plate, which is fixedly connected to one side of the positioning plate. A rotating block is rotatably connected to the bottom of the connecting plate. A right-angled positioning rod is fixedly connected to the outer wall of the rotating block. A positioning block is fixedly connected to one end of the positioning rod. A fixing bolt is fixedly connected to the bottom of the connecting plate. A spring is fixedly connected to the outer wall of the fixing bolt. The other end of the spring is fixedly connected to one of the positioning rods. A limit bolt is fixedly connected to the bottom of the connecting plate.

[0009] Preferably, the top of the base is fixedly connected with a fixing block, the number of fixing blocks corresponding to the number of positioning plates, and there are multiple sets of fixing blocks facing each other in pairs, with each set of fixing blocks located inside each set of positioning plates.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] 1. This utility model uses multiple sets of clamping plates to work together. The left and right clamping rods move synchronously in opposite directions through a gear and rack mechanism, which drives the fixed clamping plates and sliding clamping plates set at intervals to form a multi-level clamping structure. This design can position multiple components at the same time, which significantly improves production efficiency. For example, in the welding process, multiple sets of components can be welded synchronously in one clamping.

[0012] 2. This utility model achieves synchronization of clamping and positioning actions by linking the positioning plate and the clamping plate. When the clamping rod moves, the positioning plate adjusts its position synchronously to ensure that the component is always in the center position during the clamping process, thus avoiding the time-consuming secondary calibration.

[0013] 3. This utility model uses the spring and rotating block design in the positioning mechanism to enable the positioning rod to adaptively adjust the angle and pressure. When the size or shape of the component is irregular, the spring provides buffer through elastic deformation to avoid rigid collision damage to the component. At the same time, the rotating block allows the positioning rod to fit against the edge of the component at a right angle, ensuring accurate calibration of the center position.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-6A positioning device for the production of power electronic components includes a base 1. The base 1 serves as the basic support structure for the entire positioning device, providing a platform for the installation and fixation of other components. Its inner cavity accommodates components such as a support plate 2, a motor 6, and clamping rods 3, protecting and integrating these components, ensuring the overall stability and structural integrity of the device, and enabling the various components to work in an orderly and coordinated manner. The support plate 2 is fixedly connected to the inner cavity of the base 1, providing support and guidance for the clamping rods 3. Two clamping rods 3 are slidably connected through the outer wall of the support plate 2. The clamping rods 3 are driven by a clamping mechanism to achieve synchronous counter-directional movement, which is a key component for realizing the clamping action of components. It can clamp multiple components of different sizes simultaneously, improving the applicability and working efficiency of the device. Each clamping rod 3 is driven by a clamping mechanism and can move synchronously in opposite directions. Multiple clamping plates 4 are fixedly connected to the outer wall of each clamping rod 3. The clamping plate 4 fixed on one clamping rod 3 is slidably connected to another clamping rod 3. The fixed clamping plate 4 and the sliding clamping plate 4 on each clamping rod 3 are spaced apart. The top of the clamping plate 4 drives the positioning plate 5 to move through a driving component. A positioning mechanism is symmetrically arranged between each pair of positioning plates 5 to determine the center position of the component. Through the coordinated work of multiple sets of clamping plates 4, the left and right clamping rods 3 move synchronously in opposite directions through a gear 7 and rack 8 mechanism, driving the spaced fixed clamping plate 4 and the sliding clamping plate 4 to form a multi-level clamping structure. This design can position multiple components at the same time, significantly improving production efficiency. For example, in the welding process, multiple sets of components can be welded synchronously in one clamping.

[0023] Please see Figure 2-4The clamping mechanism includes a motor 6, which is connected to an external power source and is a three-phase asynchronous motor. As a power source, it provides driving force for the entire positioning device. The rotation of the output shaft drives the gear 7 to rotate, thereby driving the clamping rod 3 to move. This achieves automated operation of the device, improves positioning accuracy and efficiency, and reduces manual intervention and human error. The motor 6 is fixedly connected to the bottom of the inner cavity of the base 1. The top of the output shaft of the motor 6 is fixedly connected to the gear 7 via a coupling. One end of each clamping rod 3 is fixedly connected to a rack 8, which meshes with the gear 7. The two racks 8 are symmetrically located on both sides of the gear 7. The gear 7 and rack 8 convert the rotational motion of the motor 6 into the linear motion of the clamping rod 3. The rack 8 is symmetrically located on both sides of the gear 7, ensuring that the two clamping rods 3 can move synchronously in opposite directions. This transmission method has a simple structure and high transmission efficiency, and can accurately control the movement distance and speed of the clamping rods 3, ensuring the accuracy of the clamping force and position of the components. The top of the rack 8 is fixedly connected to a sliding plate 9, and the top of the inner cavity of the base 1 is provided with a sliding groove 10. The inner wall of the sliding groove 10 is slidably connected to the outer wall of the sliding plate 9. The sliding plate 9 on the top of the rack 8 cooperates with the sliding groove 10 on the top of the inner cavity of the base 1, which plays a guiding and stabilizing role when the clamping rods 3 move, reducing the shaking and friction during the movement of the clamping rods 3, improving the smoothness and reliability of the movement of the clamping rods 3, and further ensuring the positioning accuracy.

[0024] Please see Figure 1-3 The driving component includes a driving block 11, the bottom of which is fixedly connected to the top of the clamping plate 4. The top of the base 1 has a driving groove 12, the inner wall of which is fixedly connected to the top of the driving block 11. The top of the driving block 11 is fixedly connected to the bottom of the positioning plate 5. The number of positioning plates 5 corresponds to the number of clamping plates 4. There are multiple sets of positioning plates 5 in pairs. Each set of positioning plates 5 can move synchronously in opposite directions. The positioning plates 5 move under the drive of the driving component and cooperate with the positioning mechanism to determine the center position of the component. Through the coordinated work of multiple sets of positioning plates 5, the component can be positioned from multiple directions, improving the accuracy and stability of the positioning.

[0025] Please see Figure 1 and Figure 5-6The positioning mechanism includes a connecting plate 13, which is fixedly connected to one side of the positioning plate 5. The connecting plate 13 serves as the mounting carrier for components such as the rotating block 14 and the positioning rod 15, connecting these components to the positioning plate 5 so that they can move with the positioning plate 5, ensuring synchronous movement between the positioning mechanism and the positioning plate 5. This provides a structural basis for accurate positioning of components. The bottom of the connecting plate 13 is rotatably connected to the rotating block 14. When the positioning block 16 contacts the edge of the component, the rotating block 14 can rotate the positioning rod 15 around it by a certain angle to adapt to the irregular shape of the component, increasing the flexibility and adaptability of the positioning mechanism. It can better handle components of different shapes and sizes, improving the positioning accuracy. The outer wall of the rotating block 14 is fixedly connected to a right-angled positioning rod 15, and one end of the positioning rod 15 is fixedly connected to the positioning block 16. The positioning block 16 is used to directly contact the edge of the component. Through the adjustment of the positioning rod 15 and the contact of the positioning block 16, the positioning mechanism can achieve accurate positioning. To determine the center position of the component, a fixing bolt 17 is fixedly connected to the bottom of the connecting plate 13, and a spring 18 is fixedly connected to the outer wall of the fixing bolt 17. When the positioning block 16 contacts the component, the spring 18 will undergo elastic deformation to provide a buffering effect and avoid excessive pressure on the component, which could cause damage. The other end of the spring 18 is fixedly connected to one of the positioning rods 15. A limit bolt 19 is fixedly connected to the bottom of the connecting plate 13. The limit bolt 19 is used to limit the rotation range of the positioning rod 15 to prevent the positioning rod 15 from rotating excessively and affecting the positioning effect, thus ensuring the normal operation of the positioning mechanism and improving the accuracy and consistency of positioning. Through the design of the spring 18 and the rotating block 14 in the positioning mechanism, the positioning rod 15 can adaptively adjust its angle and pressure. When the size or shape of the component is irregular, the spring 18 provides buffering through elastic deformation to avoid rigid collision damage to the component. At the same time, the rotating block 14 allows the positioning rod 15 to fit against the edge of the component at a right angle, ensuring accurate calibration of the center position.

[0026] Please see Figure 1 and Figure 5 The top of the base 1 is fixedly connected with a fixing block 20. The number of fixing blocks 20 corresponds to the number of positioning plates 5. There are multiple sets of fixing blocks 20 in pairs. Each set of fixing blocks 20 is located inside each set of positioning plates 5. The fixing blocks 20 play an auxiliary positioning role in the positioning process, further improving the positioning accuracy and stability, enhancing the accuracy and reliability of the device in positioning components, reducing positioning errors, and ensuring the quality of subsequent production and processing.

[0027] In use, multiple power electronic components requiring positioning are placed on top of the base 1, with each component positioned appropriately between the two fixed blocks 20. The motor 6 is then turned on, and its output shaft begins to rotate, driving the gear 7 to rotate via the coupling. Since the gear 7 meshes with the racks 8 fixed to one end of the two clamping rods 3, and the two racks 8 are symmetrically located on both sides of the gear 7, the rotation of the gear 7 causes the left and right clamping rods 3 to move synchronously in opposite directions. During this process, the sliding plate 9 on the top of the rack 8 slides within the sliding groove 10 opened at the top of the inner cavity of the base 1, providing guidance and stability, ensuring the clamping rods 3... It can move smoothly. As the clamping rod 3 moves, the multiple clamping plates 4 fixed to the outer wall of each clamping rod 3 also move. The clamping plate 4 fixed on one clamping rod 3 is slidably connected to another clamping rod 3, and the clamping plates 4 fixed on each clamping rod 3 and the sliding clamping plates 4 are spaced apart. This allows for the simultaneous initial clamping operation of multiple components. The movement of the clamping plate 4 will drive the positioning plate 5 to move synchronously through the driving block 11. The positioning plate 5 will gradually move closer to the component. The connecting plate 13 fixed on one side of the positioning plate 5 will move together with the positioning plate 5. The rotating block 14 is rotatably connected to the bottom of the connecting plate 13. The right-angled positioning rod 15 fixed to the outer wall of the rotating block 14 will also approach the component. When the positioning block 16 fixed to one end of the positioning rod 15 contacts the edge of the component, if the size or shape of the component is irregular, the positioning rod 15 will rotate around the rotating block 14 at a certain angle. At the same time, the spring 18 fixed to the bottom of the connecting plate 13 will undergo elastic deformation to provide cushioning and avoid excessive pressure on the component, which could cause damage. The other end of the spring 18 is fixedly connected to one of the positioning rods 15. The limiting bolt 19 fixed to the bottom of the connecting plate 13 can limit the rotation range of the positioning rod 15. In this way, The positioning mechanism between each pair of positioning plates 5 can be adaptively adjusted to ultimately determine the center position of the component. At the same time, the fixing block 20 fixed on the top of the base 1 is located inside each group of positioning plates 5, which plays an auxiliary positioning role and further improves the positioning accuracy and stability. When the positioning plate 5 and the positioning mechanism accurately position the component in the center position, the motor 6 stops rotating, and the entire positioning process is completed. At this time, multiple components can be processed simultaneously for subsequent production operations, such as welding and assembly. After processing is completed, the motor 6 reverses, driving the clamping rod 3 and the positioning plate 5 back to the initial position for the next positioning operation.
