Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to a fully automatic mechanical structure for flattening and tinning a punch press. Background Technology
[0002] In electronic component manufacturing, many leaded parts require flattening and soldering. This fully automated mechanical structure quickly flattens the leads to the appropriate shape for easy subsequent circuit board mounting. For example, for surface-mount capacitor leads, the precise flattening operation of the mechanical structure allows them to better conform to the circuit board surface. The subsequent soldering step ensures that the leads bond well with the solder when soldered to the circuit board. The mechanical structure precisely controls the depth and time of soldering, ensuring uniform soldering quality for each lead, thus improving the soldering quality and overall performance of electronic products.
[0003] In the existing technology, the vibratory feeder in the fully automatic mechanical structure of some punch presses for flattening and tinning is a common feeding device. It uses electromagnetic vibration to make the material in the hopper rise along the spiral track. There is an inclined spiral track inside the vibratory feeder. When the electromagnetic coil is energized, it will generate vertical vibration. This vibration is transmitted to the material in the hopper, causing the material to gradually move upward on the spiral track due to the combined effect of inertia and friction.
[0004] However, in practical use, if sorting and feeding cannot be performed, the speed of manual sorting and feeding is usually much lower than that of automatic mechanical sorting and feeding. This leads to a bottleneck in the entire production process, increasing the waiting time for the machine to be fed, and preventing the fully automatic punch press flattening and tinning mechanical structure from fully utilizing its high-speed processing advantages. For example, in a high-efficiency automated production line, the mechanical structure itself can process dozens of parts for flattening and tinning per minute, but due to the slow manual sorting and feeding, only a few parts can be supplied per minute, greatly wasting the equipment's processing capacity. Therefore, to address the above-mentioned problems, a fully automatic punch press flattening and tinning mechanical structure is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1 to 3 This utility model provides an embodiment of a fully automatic mechanical structure for flattening and tinning electronic components using a punch press. The structure includes a worktable 1, which serves as the foundation support platform for the entire mechanical structure. The worktable 1 is typically made of a high-strength, wear-resistant, and stable metal material. Cast iron worktable 1 has high hardness and wear resistance, capable of withstanding the pressure and friction generated by prolonged punching, processing, and material handling operations. Its surface undergoes fine machining and grinding. A punch press 2 is fixedly connected to the right side of the worktable 1. The punch press 2 is a key device for flattening electronic components; its type depends on the requirements of the production process. Common types of punch presses include mechanical punch presses, hydraulic punch presses, and pneumatic punch presses. A [missing information - likely a component or component] is fixedly connected to the top right side of the worktable 1. Processing table 3 serves as a positioning and support platform for electronic components before flattening. Its material is a metal material that matches that of worktable 1. The steel plate processing table 3 has high strength and flatness, which can stably support electronic components and maintain their position accuracy during the stamping process. Its thickness is determined according to the pressure and structural strength requirements. The outer right side of worktable 1 is fixedly connected to the feeding plate 4. The feeding plate 4 is a component that transports the electronic components to be processed to the sorting and feeding mechanism. Its material is generally a smooth, wear-resistant metal material or engineering plastic with a certain strength, such as stainless steel plate. The stainless steel feeding plate 4 has good wear resistance and corrosion resistance and can withstand the friction and collision of electronic components during the transportation process. Its surface is polished.
[0030] A sorting and feeding mechanism is fixedly connected to the other end of the feeding plate 4. The sorting and feeding mechanism can screen and classify electronic components and transport them to the processing table 3 in a predetermined order and position, ensuring that each electronic component can accurately enter the processing area of the stamping machine 2, thereby improving production efficiency and product quality. A unloading platform 13 is fixedly connected to the rear side of the worktable 1. The unloading platform 13 serves as a temporary storage and output platform for the processed electronic components. It is made of high-strength, wear-resistant, and stable metal material, and its surface is processed to ensure high flatness, so as to ensure that the electronic components are not damaged during the unloading process and can be placed and moved stably. A discharge mechanism is fixedly connected to the top of the unloading platform 13. The discharge mechanism can sort the processed electronic components in a predetermined manner and order. The discharge mechanism includes a support plate 14, which serves as the supporting component of the discharge mechanism. The support plate 14 is made of high-strength metal material. The steel plate support plate 14 has high strength and rigidity and can stably support components such as sliding block 15, support column 16 and feeding frame 17. The front side of the support plate 14 is slidably connected to the sliding block 15. The sliding block 15 serves as the component connecting the support column 16 and the support plate 14. It is made of wear-resistant and high-strength metal material to ensure that it can maintain good accuracy and stability during long-term sliding and will not affect the normal operation of the discharge mechanism due to wear. The external side of the sliding block 15 is fixedly connected to the support column 16. The support column 16 serves as the component connecting the feeding frame 17 and the sliding block 15.
[0031] To ensure sufficient strength and rigidity to stably support the unloading frame 17 and bear the weight of the electronic components without deformation or bending during movement, the unloading frame 17 is fixedly connected to the front side of the support column 16. The unloading frame 17, as the component that directly contacts and arranges the electronic components, is made of high-strength metal. The steel plate unloading frame 17 has high strength and rigidity, enabling effective arrangement and positioning of the electronic components. Cylinders 18 are fixedly connected to both the left and right sides inside the unloading frame 17, serving as the power unit to control the opening and closing of the unloading clamp 19. The component is generally selected from standard industrial cylinders 18, such as single-acting cylinder 18 or double-acting cylinder 18. Single-acting cylinder 18 has a simple structure and low cost, and is suitable for some occasions where the clamping force requirement is not high and only unidirectional movement is required. The drive end of cylinder 18 is fixedly connected to the unloading clamping plate 19. The unloading clamping plate 19 is a component that directly contacts and clamps the electronic component to ensure that it has sufficient strength and hardness to firmly clamp the electronic component, and will not deform or wear during long-term use. The support plate 14 is externally fixedly connected to the top of the unloading platform 13.
[0032] The sorting and feeding mechanism includes a feeder 5, which serves as the material supply source for the entire mechanism. Feeders 5 come in various types, commonly including vibratory feeders 5, screw feeders 5, and belt feeders 5. The specific choice depends on the shape, size, weight of the electronic components to be processed, and the requirements of the production process. A support base 6 is fixedly connected to the bottom of the feeder 5. The function of the support base 6 is to provide stable support for the feeder 5, ensuring that it does not shake or shift during operation. The cast iron support base 6 has good stability and shock absorption performance, effectively absorbing the vibration generated during the operation of the feeder 5 and preventing it from being transmitted to other components and affecting the equipment. In terms of overall performance and precision, a frame 7 is fixedly connected to the outer right side of the workbench 1. The frame 7 serves as the mounting support structure for the drive wheel 8 and the feeding conveyor belt 9. Its material is generally high-strength steel. The channel steel frame 7 has good bending resistance and structural stability, and can withstand the tension generated by the feeding conveyor belt 9 during operation and the weight of the material, ensuring the smooth operation of the entire feeding system. The drive wheel 8 is rotatably connected inside the frame 7. The drive wheel 8 serves as the driving component of the feeding conveyor belt 9. The alloy steel drive wheel 8 has high strength and wear resistance, and can withstand the friction and tension generated by the feeding conveyor belt 9 during operation, extending the service life of the drive wheel 8.
[0033] A feeding conveyor belt 9 is fitted around the outside of the drive wheel 8. As the component that directly carries and transports electronic components, the choice of material for the feeding conveyor belt 9 is crucial. Generally, a rubber feeding conveyor belt with good wear resistance is selected. The belt has good elasticity and cushioning performance, reducing the impact and damage to electronic components during transport. Simultaneously, its high surface friction effectively prevents electronic components from slipping on the conveyor belt. An electric slide rail 10 is fixedly connected to the outer left side of the worktable 1. The electric slide rail 10 serves as a moving guide device for the clamping components. This slide rail has advantages such as high positioning accuracy, smooth movement, and adjustable speed, meeting the requirements for precise movement of the clamping components during sorting and feeding. A slider 11 is slidably connected to the outside of the electric slide rail 10. The slider 11 serves as a component connecting the clamping components and the electric slide rail 10. The material is generally made of wear-resistant, high-strength engineering plastics or metals. The left and right sides of the electric slide rail 10 are slidably connected to the clamping components. The movement of the clamping components provides precise guidance, ensuring that the clamping components can accurately reach the gripping and placement positions of electronic components, realizing efficient and accurate sorting and loading operations. The clamping components include cylinder grippers 12. As a key component for gripping and releasing electronic components, the cylinder grippers 12 are generally high-precision and high-reliability pneumatic grippers. This type of gripper is driven by a cylinder to realize the opening and closing action of the gripper, which can quickly and accurately grip and place electronic components. The outside of the cylinder grippers 12 is in contact with the outside of the loading plate 4. The outside of the cylinder grippers 12 is slidably connected to the left and right sides of the electric slide rail 10. The outside of the loading machine 5 is fixedly connected to the other end of the loading plate 4.
[0034] Reference Figures 3 to 4 A storage box 20 is fixedly connected to the front of the top of the unloading platform 13. The storage box 20 serves as a temporary storage container for the processed electronic components. Its material is usually an insulating, anti-static, and strong plastic material. The ABS plastic storage box 20 has good comprehensive performance, including high strength, good toughness, and easy processing and molding. A discharge plate 21 is fixedly connected to the right side of the storage box 20. The discharge plate 21 serves as a channel for outputting the electronic components in the storage box 20 to the next process or packaging area. The stainless steel discharge plate 21 has good wear resistance and corrosion resistance and can withstand the friction and collision of electronic components during the discharge process. Its surface is polished. A protective shell 22 is fixedly connected to the top of the unloading platform 13. The connection between the protective shell 22 and the unloading platform 13 is made by bolt connection, slot connection, or adhesive.
[0035] Bolted connections facilitate installation, disassembly, and maintenance; slotted connections provide a certain level of positioning accuracy; and adhesive connections ensure a tighter connection between the protective shell 22 and the unloading platform 13, preventing dust and debris from leaking out of the gaps. The protective shell 22 primarily protects the safety of operators and prevents debris, dust, and other contaminants from splashing into the surrounding environment during processing. The protective shell 22 is typically made of transparent acrylic glass or high-strength plastic sheet. Acrylic glass protective shells 22 offer good transparency, allowing operators to easily observe the processing inside the equipment, while also possessing sufficient strength and impact resistance to effectively block the splashing of debris and dust. The outer side of the support plate 14 contacts the inner side of the discharge plate 21, the outer bottom end of the feeding conveyor belt 9 contacts the outer top end of the processing table 3, and the outer top end of the feeding conveyor belt 9 contacts the outer bottom end of the stamping machine 2.
[0036] Working principle: First, the feeder 5 serves as the material supply source, conveying the electronic components to be processed to the processing table 3 via the feeder conveyor belt 9. The type of feeder 5 can be selected according to the characteristics of the components to be processed, such as a vibratory feeder, spiral or belt feeder 5, to ensure stable material supply. The feeder conveyor belt 9 is driven by the drive wheel 8, which can effectively carry the electronic components and reduce impact and damage during transportation. When the electronic components arrive at the processing table 3, their positions are accurately positioned, ready for stamping operations. The stamping machine 2 is fixed on the right side of the worktable 1 and is responsible for flattening the electronic components. The type of stamping machine 2 is selected according to the production process requirements, and it is a pneumatic stamping machine 2 to meet different processing needs.
[0037] After stamping, the processed electronic components are temporarily stored on the unloading platform 13. The top of the unloading platform 13 is equipped with an unloading mechanism, which is responsible for sorting and outputting the processed components. The unloading mechanism consists of a support plate 14, a sliding block 15, a support column 16, and an unloading frame 17, which ensures stable transmission of the components. The cylinder 18 controls the opening and closing of the unloading clamp 19 to clamp and release the electronic components, ensuring that the components do not shift or get damaged during the output process. The processed electronic components are moved to the storage box 20 through the unloading frame 17 as a temporary storage container. The storage box 20 is made of insulating and anti-static plastic to protect the electronic components. The unloading plate 21 is connected to the outside of the storage box 20 and is responsible for outputting the stored electronic components to the next process or packaging area.
[0038] Throughout the workflow, the electric slide rail 10 and the pneumatic gripper 12 work together to ensure that the clamping assembly can move precisely, quickly grab and place electronic components, thereby improving production efficiency and automation. The protective housing 22 provides safety protection for operators, preventing debris and dust from flying during processing and ensuring a clean and safe working environment.
