Description

Technical Field

[0001] This utility model relates to the field of power battery module assembly equipment, specifically to a power battery circuit board pin feeding device. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage systems, the reliability and production efficiency of power batteries have become core concerns in the industry. The circuit boards inside power battery modules use pins to achieve multiple functions, including mechanical fixing, conductive interconnection, heat dissipation assistance, positioning calibration, and modular assembly / disassembly.

[0003] 1. Mechanical fixing: Pins securely connect individual battery cells or battery modules to the circuit board to ensure structural stability under high vibration conditions;

[0004] 2. Conductive interconnection: Some plated pins also have conductive properties, which can reduce the resistance of the connection point and improve the current transmission efficiency of the overall system when used with conductive pads or conductive adhesives.

[0005] 3. Heat dissipation assistance: Metal pins connect to the heat dissipation structure through direct contact or thermal interface materials, providing a heat conduction channel for the circuit board and surrounding components, and helping to dissipate heat quickly;

[0006] 4. Positioning and calibration: In the process of assembling multiple components, pins are often used as reference positioning points to enable the alignment accuracy of parts to reach ±0.1 mm level;

[0007] 5. Modular design: The pin-type interface facilitates quick disassembly and maintenance of battery units, and has significant advantages when replacing consumable parts or upgrading modules.

[0008] However, the existing process for feeding circuit board pins in production lines has the following shortcomings:

[0009] Manual feeding is inefficient: Traditional manual or semi-automatic feeding involves frequent material changes and a high error rate, making it difficult to meet the requirements of large-volume, high-cycle production.

[0010] Insufficient positioning accuracy: With existing vibratory feeders or hoppers, the pins are prone to overlapping, jamming, or incorrect posture, which makes it impossible for the subsequent picking mechanism to grasp the material steadily.

[0011] The cycle time is difficult to increase: In high-vibration and mixed-product scenarios, the feeding system takes a long time to adjust and cannot keep up with the rapid switching of multiple types of pins.

[0012] The equipment is complex to maintain: the vibrating hopper, which has a simple structure, relies on experience to adjust the vibration frequency and discharge parameters, resulting in high on-site maintenance costs and downtime.

[0013] Therefore, there is an urgent need for an automatic feeding device that can achieve high precision, low error, and rapid switching based on the characteristics of pins (small size, high rigidity, multiple surface treatments) to meet the comprehensive requirements of assembly cycle time, yield, and stability on the power battery assembly production line. Utility Model Content

[0014] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a power battery circuit board pin feeding device with reasonable structural design, accurate positioning, stable movement and strong practicality.

[0015] To achieve the above objectives, this utility model is implemented through the following technical solution: a power battery circuit board pin feeding device, comprising a base plate, a support, a linear gear, a cylinder, a turntable, a buffer block, a rotating rod, a rotating rod fixing frame, and a pin clamp. The base plate is provided with a support, and the lower part of the support is provided with a cylinder. The cylinder cooperates with the linear gear, the linear gear is connected to the turntable, the turntable is connected to the rotating rod, the turntable is provided with a rotating rod fixing frame, the rotating rod is provided on the rotating rod fixing frame, a limit block is provided at the bottom of the rotating rod fixing frame, the limit block cooperates with two buffer blocks on the support, and a pin clamp is provided at the end of the rotating rod.

[0016] Preferably, the limiting block is a T-shaped block, and the protruding end of the T-shaped block is matched with the limiting block 10 for limiting.

[0017] The beneficial effects of this utility model are:

[0018] 1. Precise positioning: The rotating rod is driven by gear meshing, which has high precision and can accurately achieve positioning. This effectively avoids errors in the pin assembly process and improves the accuracy of pin assembly and product quality.

[0019] 2. Stable movement: The limiting block at the bottom of the rotating rod fixing frame and the buffer block on the support cooperate to stabilize and limit the movement of the rotating rod, ensuring that the rotating rod accurately reaches the designated position, making the entire loading and assembly process more stable and reliable.

[0020] 3. Compact structure: The overall structure of the device is relatively compact, and the connection and cooperation between various components are tight. It realizes the functions of pin gripping and assembly within a limited space, and is suitable for production environments with high space requirements.

[0021] 4. High degree of automation: The rotation of the rotating rod and the gripping and assembly of the pin are achieved by using a cylinder to drive the gear, which reduces manual intervention, improves production efficiency, and conforms to the trend of automated production.

[0023] Figure 1 This is a schematic diagram of the structure of this utility model;

[0024] Figure 2 This is a schematic diagram of another orientation of the present invention. Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Reference Figure 1-2 The specific embodiment adopts the following technical solution: a power battery circuit board pin feeding device, including a base plate 1, a support 2, a linear gear 3, a cylinder 4, a turntable 5, a buffer block 6, a rotating rod 7, a rotating rod fixing frame 8, and a pin clamp 9. The base plate 1 is provided with a support 2, and the lower part of the support 2 is provided with a cylinder 4. The cylinder 4 cooperates with the linear gear 3. The linear gear 3 is connected to the turntable 5. The turntable 5 is connected to the rotating rod 7. The turntable 5 is provided with a rotating rod fixing frame 8, and the rotating rod 7 is provided on the rotating rod fixing frame 8. The bottom of the rotating rod fixing frame 8 is provided with a limit block 10, which cooperates with two buffer blocks 6 on the support 2. The end of the rotating rod 7 is provided with a pin clamp 9.

[0027] It is worth noting that the limiting block 10 is a T-shaped block, and the protruding end of the T-shaped block is engaged with the limiting block 10 for limiting.

[0028] The working principle of this specific implementation method is as follows:

[0029] After the device is started, the cylinder at the bottom of the support on the base plate begins to work. The cylinder engages with the linear gear, driving the linear gear to move. The movement of the linear gear drives the connected turntable to rotate. Since the turntable is connected to the rotating rod, and the rotating rod is mounted on the turntable via a rotating rod fixing bracket, the rotation of the turntable causes the rotating rod to rotate around a certain axis. During the rotation of the rotating rod, the T-shaped limit block at the bottom of the rotating rod fixing bracket engages with two buffer blocks on the support to ensure that the rotating rod rotates to the appropriate position and stabilizes. After the rotating rod rotates to the designated position, the pin clamp at its end grabs the pin, and then through continued rotation or other actions, the pin is accurately installed onto the power battery circuit board, completing the pin loading and assembly process.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
