Description

Technical Field

[0001] This application relates to the field of auxiliary equipment technology for robot unpacking carts, and in particular to a fixing component for the end of a drag chain of a robot unpacking cart. Background Technology

[0002] In the fields of automated logistics and industrial production, robotic unpacking carts are widely used for material handling and unpacking. Cable chains, as a key component, are responsible for protecting and guiding various cables, oil pipes, and other pipelines in an orderly manner, ensuring that they are not damaged by excessive stretching, twisting, or external collisions during frequent movement, turning, and starting / stopping of the cart, thus guaranteeing the continuous and stable operation of the robotic unpacking cart.

[0003] However, existing cable chain end fixing components have significant defects. Regarding stability, traditional fixing methods typically use simple clips or bolts for fastening. Under the high-speed operation, frequent acceleration and deceleration of robotic unpacking carts, and the vibrations of complex operating conditions, the cable chain ends are prone to loosening and slipping. For example, in some automated warehouses, unpacking carts quickly shuttle between shelves; slippage of the cable chain causes internal pipelines to rub against the cart body, resulting in severe wear and even short circuits and oil leaks. This not only increases equipment maintenance costs but also seriously affects logistics operation efficiency.

[0004] In terms of adaptability, different models of robotic unpacking vehicles and different application scenarios require different cable chain sizes and materials. However, existing fixing components cannot precisely adjust the clamping force. For large-sized or high-strength metal cable chains, insufficient clamping force will result in unstable fixing; for small-sized or fragile plastic cable chains, excessive clamping force can easily cause the cable chain to break. In actual production, due to the inability to adapt to different cable chains, it is often necessary to frequently replace fixing components, increasing time and economic costs.

[0005] Meanwhile, due to the complex working environment of the robotic unpacking vehicle, with frequent vibrations and impacts, existing fixed components generally lack buffer structures. Under long-term impacts, the cable chain and fixed components suffer severe fatigue damage, shortening the normal service life of the equipment.

[0006] To address this issue, a fixing component for the end of the cable chain of a robot unpacking cart has been invented to solve the problems mentioned in the background art. Utility Model Content

[0007] The present invention aims to provide a fixing component for the end of the cable chain of a robot unpacking cart, which solves the shortcomings of existing fixing components in terms of fixing stability, adaptability, ease of installation and buffer protection, thereby improving the reliability and service life of the robot unpacking cart cable chain system.

[0008] The robotic unpacking trolley cable chain end fixing component provided in this application adopts the following technical solution: it includes a fixing base and a cable chain. The fixing base is integrally formed from high-strength metal material and has multiple mounting holes. The fixing base is provided with a clamping mechanism, an adjusting component, a positioning device, and a buffer structure. The clamping mechanism is used to firmly clamp the end of the cable chain to prevent the cable chain from slipping during the operation of the robotic unpacking trolley. The adjusting component is used to precisely adjust the clamping force of the clamping arm on the cable chain to adapt to cable chains of different sizes and materials. The positioning device is used to achieve rapid positioning of the cable chain to ensure installation accuracy. The buffer structure is used to protect the cable chain and the fixing component.

[0009] Optionally, the clamping mechanism includes two symmetrically arranged clamping arms, with anti-slip rubber pads provided on the opposite sides of the two clamping arms. The two clamping arms can move relative to each other or away from each other, and the clamping arms are slidably connected to the fixed base.

[0010] Optionally, the adjusting assembly includes an adjusting screw, which is rotatably connected to a fixed base. The adjusting screw has threads with opposite directions of rotation. Both sides of the adjusting screw are threadedly connected to the clamping arms on their corresponding sides. A drive motor is provided on the fixed base, and the output end of the drive motor is fixedly connected to the adjusting screw.

[0011] Optionally, the positioning device includes a positioning pin and a positioning groove. The positioning groove is provided at the end of the drag chain. A fixing spring is fixedly fitted on the positioning pin. The positioning pin is slidably mounted on the fixed base and can be inserted into the positioning groove. The other end of the fixing spring is fixed on the fixed base.

[0012] Optionally, the buffer structure includes an elastic buffer pad, which is disposed on both sides of the clamping arm and located between the fixed base and the clamping arm.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. Stable and secure: The symmetrically arranged clamping arms, which can move relative to or away from each other, along with anti-slip rubber pads, can firmly hold the end of the cable chain, effectively preventing the cable chain from slipping during the operation of the robot unpacking trolley and ensuring pipeline safety.

[0015] 2. Precise Adaptation: The adjusting screw works in conjunction with the drive motor to precisely adjust the clamping force of the clamping arm on the cable chain, adapting to cable chains of different sizes and materials, improving the versatility of the fixing components and reducing replacement costs.

[0016] 3. Quick installation: The combination of positioning pins, positioning slots, and fixing springs enables rapid positioning of the cable chain, ensuring installation accuracy, significantly shortening installation time, and improving work efficiency.

[0017] 4. Long-term protection: Elastic buffer pads are set on both sides of the clamping arm to effectively buffer vibration and impact, reduce damage to the cable chain and fixed parts, and extend the service life of the equipment. Attached Figure Description

Therefore, they should not be construed as limitations on the present utility model.

[0025] Reference Figure 1 , Figure 2One embodiment shown is as follows: The fixing component includes a fixing base 1 and a cable chain 2 to be fixed. In this embodiment, the fixing base 1 is the basic support structure of the entire fixing component, and it is integrally formed from a high-strength metal material. This material and forming method ensure that the fixing base 1 has sufficient strength and stability to withstand various forces during the operation of the cable chain 2. Multiple mounting holes 3 are provided on the fixing base 1 to facilitate the installation of the entire fixing component onto the robot unpacking cart using bolts or other connecting parts. A clamping mechanism 4, an adjusting component 5, a positioning device 6, and a buffer structure 7 are sequentially connected to the fixing base 1. They work together to effectively fix and protect the end of the cable chain 2.

[0026] The implementation principle of the above embodiment is as follows: the fixed base 1 is connected to the robot unpacking trolley through the mounting hole 3, providing an installation base for subsequent components. Each component is fixed, adjusted, positioned and buffered based on the fixed base 1 to protect the end of the cable chain 2.

[0027] Reference Figure 3 , Figure 4 One embodiment shown is as follows: The clamping mechanism 4 is connected to the fixed base 1, and includes two symmetrically arranged clamping arms 8. In this embodiment, the two clamping arms 8 are symmetrically distributed with respect to the fixed base 1. They are slidably connected to the fixed base 1 by means of a slide rail slider. This connection method allows the clamping arms 8 to move stably relative to or away from each other. On the opposite side of the two clamping arms 8, anti-slip rubber pads 9 are respectively installed. The anti-slip rubber pads 9 are attached to the clamping arms 8 with strong adhesive.

[0028] The implementation principle of the above embodiment is as follows: when it is necessary to hold the cable chain 2 tightly, the two clamping arms 8 move relative to each other, and the anti-slip rubber pad 9 contacts the cable chain 2. By utilizing the high friction and flexibility of the rubber, the end of the cable chain 2 is tightly held to prevent the cable chain 2 from sliding during operation. At the same time, the flexible rubber pad can also avoid causing hard damage to the surface of the cable chain 2.

[0029] Reference Figure 3 One embodiment shown is as follows: the adjusting assembly 5 is mounted on the fixed base 1, and its core component is the adjusting screw 10. In this embodiment, the adjusting screw 10 is rotatably connected to the fixed base 1 via bearings to ensure smooth rotation of the adjusting screw 10. The adjusting screw 10 is machined with threads of opposite directions, and its two sides are respectively threadedly connected to the corresponding clamping arms 8. A drive motor 11 is fixedly mounted on the fixed base 1, and the output end of the drive motor 11 is fixedly connected to the adjusting screw 10 via a coupling.

[0030] The implementation principle of the above embodiment is as follows: After the drive motor 11 starts, it drives the adjusting screw 10 to rotate. Since the threads on both sides of the adjusting screw 10 rotate in opposite directions, according to the principle of thread transmission, the two clamping arms 8 that are threadedly connected to the adjusting screw 10 will move relative to each other or in opposite directions, thereby realizing the adjustment of the clamping force of the drag chain 2 to adapt to drag chains 2 of different sizes and materials.

[0031] Reference Figure 3 One embodiment shown is as follows: the positioning device 6 is installed on the fixed base 1, which includes a positioning pin 12 and a positioning groove 13 opened at the end of the drag chain 2. In this embodiment, the positioning pin 12 is slidably installed on the fixed base 1 through the guide hole. A fixing spring 14 is fitted on the positioning pin 12. One end of the fixing spring 14 is fixed to the positioning pin 12, and the other end is fixed to the fixed base 1. The positioning groove 13 is pre-machined at the end of the drag chain 2.

[0032] The implementation principle of the above embodiment is as follows: When installing the cable chain 2, the cable chain 2 is brought close to the fixed base 1. Under the elastic force of the fixed compression spring 14, the positioning pin 12 is automatically inserted into the positioning groove 13 at the end of the cable chain 2, so as to realize the rapid positioning of the cable chain 2, ensure the installation accuracy, and also facilitate the subsequent clamping mechanism 4 to clamp the cable chain 2.

[0033] Reference Figure 1 , Figure 2 , Figure 5 One embodiment shown is as follows: the buffer structure 7 is associated with the fixed base 1 and the clamping arm 8, and includes an elastic buffer pad 15. In this embodiment, the elastic buffer pad 15 is disposed on both sides of the clamping arm 8 by means of double-sided tape or slots, and is located between the fixed base 1 and the clamping arm 8.

[0034] The implementation principle of the above embodiment is as follows: when the robot unpacking trolley generates vibration or impact during operation, the elastic buffer pad 15 can absorb and buffer this energy, reduce the rigid collision between the fixed base 1 and the clamping arm 8, thereby protecting the cable chain 2 and the fixed components and extending their service life.

[0035] The working principle of this device is as follows: During installation, first align the positioning pin 12 with the positioning groove 13 at the end of the cable chain 2. Under the action of the fixing spring 14, the positioning pin 12 is quickly inserted to complete the positioning. Next, start the drive motor 11 on the fixed base 1, and its output end drives the adjusting screw 10 to rotate. Because the threads on both sides of the adjusting screw 10 have opposite directions and are threadedly connected to the corresponding clamping arms 8, the two clamping arms 8 move relative to each other, gradually clamping the end of the cable chain 2. According to the actual situation of the cable chain 2, the clamping force can be precisely adjusted by controlling the rotation angle of the motor. The anti-slip rubber pad 9 further prevents the cable chain 2 from sliding. During operation, if the robot unpacking cart is subjected to vibration and impact, the elastic buffer pad 15 located on both sides of the clamping arms 8 and between the fixed base 1 and the clamping arms 8 will absorb the impact energy, protect the cable chain 2 and the fixed components, avoid damage caused by vibration and impact, ensure that the cable chain 2 can work stably under various working conditions, and ensure the operation of the robot unpacking cart.

[0036] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
