TECHNICAL FIELD

[0001] The utility model relates to the automation technical field especially is related to a solar energy heat collecting pipe automatic feeding and discharging clamp. BACKGROUND

[0002] In the production process of the solar energy heat collecting pipe, the feeding and discharging link of the heat collecting pipe on the conveying line is very important. The traditional manual feeding and discharging mode has many disadvantages: on the one hand, the manual operation efficiency is low, it is difficult to meet the demand of large-scale production, and the labor intensity is large, which easily leads to the fatigue of workers, and further affects the production progress; on the other hand, the production workshop of the heat collecting pipe is high in temperature, and the environment is bad, which affects the physical and mental health of the operators. Therefore, a robot capable of automatic feeding and discharging needs to be developed; the difficulty lies in that due to the factors such as inaccurate precision control, the surface of the heat collecting pipe is easily scratched and bumped, which reduces the product quality and increases the rate of defective products, and brings additional economic losses to the enterprise. In addition, in order to meet the production demand, the conveying line is always in a running state during the feeding and discharging process, and the existing robot feeding and discharging cannot accurately follow, and it is difficult to ensure the accurate position during the arrangement and placement of the heat collecting pipe. At the same time, if the robot cannot accurately follow, it will directly lead to the rupture of the heat collecting pipe due to excessive force. Therefore, how to realize the automation of the feeding and discharging of the solar energy heat collecting pipe, improve the production efficiency, reduce the labor cost and reduce the damage to the products has become a problem to be solved for the solar energy heat collecting pipe production enterprises.

[0022] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0023] Example 1, in conjunction with Appendix Figures 1-3 A clamp for automatically loading and unloading solar collector tubes includes a connecting seat 1, slide rails 2, and mounting base 3. The connecting seat 1 is mounted on the actuator end of a robotic arm and serves as a key component connecting the clamp to the robotic arm; its stability and installation accuracy directly affect the overall performance of the clamp. Multiple slide rails 2 are spaced apart on the connecting seat 1, preferably two slide rails 2 spaced apart. This design not only facilitates installation but also effectively reduces operating costs and improves the economic efficiency of the clamp while ensuring its strength.

[0024] The mounting base 3 is slidably engaged with the slide rail 2 via a slider 4, meaning the mounting base 3 can slide freely left and right relative to the connecting base 1 along the slide rail 2. This sliding engagement design gives the mounting base 3 lateral flexibility, allowing for position adjustment according to actual working conditions. Multiple gripper cylinders 6 are arranged in an array on the mounting base 3. Through a reasonable layout, it is ensured that the gripper cylinders 6 are evenly stressed during operation, improving the stability and reliability of gripping.

[0025] A pneumatic telescopic cylinder 5 is installed between the mounting base 3 and the connecting base 1. The pneumatic telescopic cylinder 5 can be mounted on the mounting base 3, with its piston rod extended and securely connected to the connecting base 1 via a bracket; or the pneumatic telescopic cylinder 5 can be mounted on the connecting base 1, with its piston rod extended and securely connected to the mounting base 3 via a bracket. As a key driving component of the clamp, the pneumatic telescopic cylinder 5 functions to move the mounting base 3 to a fixed position by inflating and extending it, maintaining a rigid connection between the mounting base 3 and the connecting base 1, ensuring the entire clamp and heat collection tube remain stable during the unloading process; and to allow the mounting base 3 to slide freely along the slide rail 2 by deflating it, enabling automatic displacement compensation based on the position of the heat collection tube during clamping.

[0026] In this way, when the heat collecting tube is clamped, the clamp is first sent to the clamping position by the mechanical arm, then the pneumatic telescopic cylinder 5 is exhausted, so that the mounting seat 3 is in a free state capable of sliding along the slide rail 2; then the mechanical arm acts until the heat collecting tube enters between the two clamping jaws of the clamping jaw cylinder 6; during this process, since the mounting seat 3 is in a free state, even if there is a small distance deviation of the clamping jaw of the clamping jaw cylinder 6 relative to the heat collecting tube, it can be automatically displaced and compensated when the clamping jaw of the clamping jaw cylinder 6 touches the heat collecting tube, thereby preventing the clamping jaw of the clamping jaw cylinder 6 from damaging the heat collecting tube, effectively protecting the surface quality of the heat collecting tube, reducing the rate of defective products, and improving production efficiency.

[0027] It is worth noting that during the clamping process, the conveying line is still in a moving conveying state of 1 cm / s, and the free movement of the mounting seat 3 can automatically compensate for the displacement distance of the heat collecting tube, without the need for the mechanical arm to move to follow, thereby greatly reducing the control difficulty of the mechanical arm, simplifying the programming and debugging process of the control system, and improving the intelligent level and operating efficiency of the entire system. After the clamping jaw cylinder 6 clamps the heat collecting tube and pulls it out of the conveying line, the pneumatic telescopic cylinder 5 is inflated, so that the mounting seat 3 and the connecting seat 1 are in a rigid connection state, and then the mechanical arm is controlled to act to place the heat collecting tube at the unloading station, which can ensure that the entire clamp and the heat collecting tube are in a stable state during the unloading action, thereby improving safety and reliability; at the same time, before the next clamping action, the pneumatic telescopic cylinder 5 remains inflated, thereby ensuring that the clamping jaw cylinder 6 is accurately positioned at the clamping position, improving the accuracy and efficiency of clamping.

[0028] It is worth noting that before the pneumatic telescopic cylinder 5 is exhausted, the two ends of the mounting seat 3 need to be at the same horizontal height to prevent the mounting seat 3 from automatically sliding to the lower side under its own gravity after the pneumatic telescopic cylinder 5 is exhausted, resulting in a large positional deviation between the clamping jaw cylinder 6 and the corresponding heat collecting tube, affecting the clamping accuracy and work efficiency.

[0029] Example 2, in combination with the attached Figures 1-3 A solar heat collecting tube automatic loading and unloading clamp, based on example 1, the mounting seat 3 is arranged with two rows of clamping jaw cylinders 6 above and below, and the two rows of clamping jaw cylinders 6 are arranged in staggered positions. It can effectively deal with the dense arrangement of heat collecting tubes and avoid mutual interference between adjacent two clamping jaw cylinders 6. The inner side of the clamping jaw of the clamping jaw cylinder 6 is provided with a flexible protective pad 7. It can effectively protect the heat collecting tube and prevent the clamping jaw of the clamping jaw cylinder 6 from damaging or scratching the heat collecting tube.

[0030] Further, the clamping jaw cylinder 6 is provided with a contact switch on one side between two clamping jaws, not shown in the figure. When the heat collecting pipe is clamped, the heat collecting pipe can trigger the contact switch when it is in the appropriate position between the two clamping jaws, thereby sending a clamping signal to make the clamping jaw cylinder 6 act, and the two clamping jaws clamp the heat collecting pipe, which can prevent the clamping jaw cylinder 6 from being too far away from the heat collecting pipe when clamping the heat collecting pipe to effectively clamp, or too close to the heat collecting pipe to hit the heat collecting pipe.

[0031] Further, the mounting seat 3 is in a rhombus structure. The weight of the mounting seat 3 can be effectively reduced, and the non-acting part of the mounting seat 3 is removed, and the safe moving range of the mounting seat 3 is increased.

[0032] Embodiment 3, combined with the attached Figure 4 A solar heat collecting pipe automatic feeding and discharging clamp, based on the embodiments 1 or 2, in order to ensure the reliability of the mechanical arm clamping, and prevent the heat collecting pipe from being broken due to excessive local clamping force, a transition plate is arranged at the execution end of the mechanical arm, and two upper and lower clamps are arranged on the transition plate, as shown in the attached Figure 4 The two clamps are cooperated to clamp the heat collecting pipe.

[0033] The parts not described in the utility model are prior art, and for those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and all changes falling within the meaning and scope of the equivalent elements are intended to be included in the utility model.
