Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for lead frame mold processing, and specifically relates to a positioning device for lead frame mold processing. Background Technology

[0002] Positioning devices for leadframe mold processing are core auxiliary equipment in the leadframe production process. Their core function is to perform high-precision positioning and stable clamping of the processing mold. By precisely constraining the spatial position of the mold and limiting displacement deviation, this device can effectively avoid problems such as dimensional errors and form and position deviations caused by mold offset and shaking during processing. It ensures that key indicators such as lead spacing, slot accuracy, and flatness of the leadframe meet design requirements, thereby guaranteeing product consistency and assembly compatibility. This lays a solid quality foundation for subsequent packaging, welding and other processes, and is one of the key pieces of equipment for improving leadframe production efficiency and finished product qualification rate.

[0003] However, existing positioning devices for lead frame mold processing have significant shortcomings in terms of convenience in practical applications. They lack the ability to quickly adapt to and fix molds of different models and sizes, and cannot achieve efficient clamping and positioning according to mold specifications. When changing molds of different specifications, it is often necessary to spend extra time to adjust the mechanical structure or replace parts. It is impossible to directly and quickly complete the mold fixing operation. The operation process is cumbersome and time-consuming, which not only reduces the efficiency of mold changing, but also affects the smoothness of the overall processing flow, causing many inconveniences in actual use.

[0004] To address the aforementioned problems, this application proposes a positioning device for processing lead frame molds. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a positioning device for processing lead frame molds, which features rapid adaptation to molds of different specifications and significantly improves mold changing efficiency.

[0010] As a preferred technical solution of this utility model, two sets of protective shells are fixedly connected to the outer surface of the support plate, and each of the protective shells is sleeved on the outside of the brake motor.

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the upper surface of each sliding frame, and the upper surface of each connecting plate is fixedly connected to the bottom surface of the electric push rod.

[0012] As a preferred embodiment of this utility model, each of the electric push rods has a reinforcing frame fixedly connected to its telescopic end, and the inner wall of each reinforcing frame is fixedly connected to the outer surface of the positioning frame.

[0013] As a preferred technical solution of this utility model, a protective sleeve is fixedly connected to the outer surface of each positioning frame, and each protective sleeve is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up the cooperation of the brake motor, threaded rod and sliding frame, two sets of positioning frames can be driven to move synchronously or in opposite directions along the horizontal direction of the support plate, realizing rapid adaptation to molds of different width specifications. Then, with the help of the telescopic action of the electric push rod, the positioning frame is driven to move vertically, quickly completing the clamping and unlocking of the mold. There is no need for tedious manual adjustment or replacement of parts, which greatly shortens the mold change time and significantly improves the mold change efficiency and ease of operation. At the same time, the self-locking function of the brake motor can improve the stability after positioning, prevent the mold from shifting during processing, and ensure positioning accuracy. The overall structure is centrally controlled by the controller, which is simple to operate and highly automated. It effectively solves the technical problems of poor adaptability and tedious mold change of the existing device, and takes into account both positioning accuracy and ease of use, adapting to the processing needs of multi-specification molds in mass production.

In this embodiment, the controller 2 adopts a PLC programmable logic controller, which has a multi-channel digital input / output interface. It can accurately receive external control signals and output pulse commands to realize synchronous linkage control of the brake motor 7 and the electric push rod 11. It supports the modification of positioning parameters through the touch screen or host computer, adapts to the positioning requirements of different mold specifications, and has strong anti-interference ability, which can adapt to the electromagnetic interference of the industrial processing environment. The brake motor 7 adopts a servo brake motor and is equipped with an electromagnetic braking device, which can realize immediate self-locking after stopping the machine to prevent the positioning frame 12 from shifting due to external force. At the same time, the position control accuracy of the servo motor is high, ensuring the positioning accuracy of the mold in the horizontal direction. The electric push rod 11 adopts a ball screw electric push rod, which has high transmission efficiency and smooth operation. It can accurately control the vertical lifting of the positioning frame 12, realize the rapid clamping and unlocking of the mold, and has an overload protection function to prevent damage to the equipment due to excessive load.

[0018] Specifically, two sets of fixing pins 4 are provided on the upper part of the support plate 1. The bottom end of each fixing pin 4 passes through the support plate 1 and extends to the bottom of the support plate 1. In this embodiment, the fixing pins 4 are used to realize the quick positioning and installation of the support plate 1 and the processing table, improve the overall installation stability of the device, and avoid the device from shifting due to processing vibration.

[0019] Specifically, the bottom surface of the controller 2 is fixedly connected to the mounting plate 3, and the right side of the mounting plate 3 is fixedly connected to the left side of the support plate 1. In this embodiment, the controller 2 is securely mounted on the side of the support plate 1 by the mounting plate 3, ensuring that the controller 2 is firmly installed and convenient for operators to operate nearby.

[0020] Specifically, each brake motor 7 has a support frame 6 fixedly connected to its bottom surface. The side of each set of support frames 6 that is close to each other is fixedly connected to the outer surface of the support plate 1. In this embodiment, the brake motor 7 is supported and fixed by the support frame 6 to ensure the coaxiality of the motor during operation and reduce the impact of vibration on the transmission accuracy.

[0021] Specifically, two sets of protective shells 5 are fixedly connected to the outer surface of the support plate 1. Each protective shell 5 is fitted onto the outside of the brake motor 7.

In this embodiment, the connecting plate 10 realizes the rigid connection between the electric push rod 11 and the sliding frame 8, which improves the structural stability when the two are linked and ensures accurate transmission of thrust.

[0023] Specifically, each electric push rod 11 has a reinforcing frame 14 fixedly connected to its telescopic end. The inner wall of each reinforcing frame 14 is fixedly connected to the outer surface of the positioning frame 12. In this embodiment, the reinforcing frame 14 enhances the connection strength between the electric push rod 11 and the positioning frame 12, preventing the positioning frame 12 from deforming under force when clamping the mold and ensuring positioning accuracy.

[0024] Specifically, a protective sleeve 13 is fixedly connected to the outer surface of each positioning frame 12. Each protective sleeve 13 is made of rubber. In this embodiment, the rubber protective sleeve 13 buffers the clamping impact between the positioning frame 12 and the mold, while preventing the mold surface from being pinched and scratched, thus protecting the mold precision.

[0025] The working principle and usage process of this utility model are as follows: First, the support plate 1 is precisely installed and fixed at the designated position on the processing table using the fixing pin 4 to ensure the overall stability of the device and prevent displacement during processing. The operator inputs the specifications of the mold to be processed through the controller 2. The controller 2 sends a drive command to the brake motor 7 according to the parameters. After the brake motor 7 starts, it drives the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the sliding frame 8, and the sliding frame 8 is slidably engaged with the support plate 1, the two sets of sliding frames 8 move synchronously or in opposite directions along the horizontal direction of the support plate 1 until the positioning frame 12 moves to a position that matches the width of the mold. Subsequently, the controller 2 controls the electric push rod 11 to start. The telescopic end of the electric push rod 11 retracts downward, driving the positioning frame 12 to move vertically downward until the protective sleeve 13 is tightly fitted with the outer surface of the mold, completing the clamping and fixing of the mold. At this time, the brake... The brake motor 7 activates its self-locking function, which, together with the structural reinforcement of the reinforcing frame 14, ensures the stability of the positioning frame 12 and prevents mold displacement caused by processing vibration. When it is necessary to change to a different mold size, the operator issues an unlocking command through the controller 2. The telescopic end of the electric push rod 11 extends upward, the positioning frame 12 disengages from the mold, the brake motor 7 releases its self-locking and drives the threaded rod 9 to rotate in the opposite direction. The sliding frame 8 resets or adjusts to the appropriate position for the new mold. Repeating the above clamping steps completes the quick mold change. Throughout the process, the protective shell 5 protects the brake motor 7, isolating it from metal shavings and cutting fluid. At the same time, the mounting plate 3 ensures that the controller 2 is securely installed and easy to operate, while the connecting plate 10 ensures the linkage stability between the electric push rod 11 and the sliding frame 8. The whole process is automated through the controller 2, eliminating the need for tedious manual adjustments and significantly improving mold change efficiency and positioning accuracy.
