Description

Technical Field

[0001] This invention relates to the field of relay manufacturing technology, and more specifically, to a cooling device for relay manufacturing. Background Technology

[0002] In existing technologies, relays undergo key processes during production, including dispensing, thermosetting, and cooling. The thermosetting process after dispensing aims to rapidly bring the adhesive to its designed strength through heating, while the subsequent cooling process ensures that the relay temperature steadily drops back to ambient temperature, guaranteeing structural stability and reliable performance. Currently, the mainstream cooling process often employs a conveyor belt assembly line combined with continuous water immersion for heat dissipation. Although this enables continuous operation, during the conveying and cooling process, the densely arranged relays inevitably collide with each other due to mechanical vibration, conveyor belt shaking, or water flow impact. Existing equipment often uses rigid or limitedly flexible simple clamps to fix the relays, which are insufficient to effectively buffer and absorb the instantaneous impact force generated by such accidental collisions.

[0003] The aforementioned technical defects result in a significant risk that relays may detach from their clamping stations due to mutual collisions on continuously operating production lines. Once detached, not only will the product itself be damaged by falling or being squeezed, directly causing scrap losses, but the fallen part may also interfere with the conveyor path, triggering a chain reaction of collisions with subsequent products or even production line blockages, seriously threatening the stable operation and overall efficiency of the production line. At the same time, in scenarios involving water cooling, if fallen relays are not detected in time, they may also cause potential electrical safety risks or equipment failures. This not only affects the physical safety and product consistency of the production process, but also poses a significant challenge to production cycle and cost control. Summary of the Invention

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a cooling device for relay production, comprising a fixedly installed frame, a relay body, and a water tank; and further comprising a conveying mechanism and a follow-up mechanism, wherein the conveying mechanism includes a telescopic component and an adjusting component, and the relay body can be continuously conveyed through the conveying mechanism, and the relay body is cooled by the water tank to restore it to the required hardness; The telescopic component allows the relay body to be adjusted vertically during transmission. As vertical displacement occurs, the relay body is driven into the water tank for cooling. After immersion cooling is completed, the relay body leaves the water tank. The adjustment component changes the vertical position difference of the relay body, allowing relay bodies of different models to be fully immersed in the water tank for cooling. The follow-up mechanism ensures that the relay body, after being clamped and fixed, can be displaced in the vertical direction when affected by external force, and is in a decoupled state from the vertical position of the telescopic component.

[0006] Preferably, the telescopic assembly includes two lateral frames symmetrically arranged on the frame. Each lateral frame is rotatably connected to an upper belt and a lower belt at its upper and lower ends. Multiple full-coverage sleeves are installed at equal intervals on the outer side wall of the upper belt, and multiple half-coverage sleeves are installed at equal intervals on the outer side wall of the lower belt.

[0007] Preferably, each of the full-coverage sleeves is fixedly installed inside, and each of the half-coverage sleeves is slidably connected to a lifting sleeve. The lower end of the fixed sleeve is coaxially installed with a telescopic sleeve, and the telescopic sleeve is slidably connected inside the lifting sleeve.

[0008] Preferably, an air guide pipe is coaxially arranged inside the lifting sleeve, the lowermost end of the air guide pipe is connected to the outside, a compression spring is provided at the upper end of the air guide pipe, and the other end of the compression spring abuts against the inside of the telescopic sleeve.

[0009] Preferably, a motor is fixedly mounted on the lateral frame, and transmission wheels are respectively connected to the upper and lower belts. The transmission wheels are rotatably connected inside the lateral frame, and a transmission belt is connected between the transmission wheels and the drive end of the motor.

[0010] Preferably, the adjustment assembly includes a fixed plate installed in the side frame, with rotating shafts rotatably connected to both ends of the fixed plate, and adjusting belts rotatably connected to the two rotating shafts respectively. A follower rod is provided on the lifting sleeve, and the follower rod is attached to the lower end face of the adjusting belt.

[0011] Preferably, each of the rotating shafts is provided with a tension spring, and the other end of the tension spring is connected to the fixed plate. An extension plate is fixedly provided on the side wall of the fixed plate, and an intermediate bolt is threadedly connected to the extension plate. The upper end of the adjusting belt abuts against a top block, and the intermediate bolt abuts against the top block.

[0012] Preferably, the follower mechanism includes a follower sleeve, two fitting rods are installed on the side wall of the follower sleeve, and a fitting groove is provided in the lifting sleeve. The fitting rods are slidably connected in the fitting groove, and a follower spring is provided on the fitting rods, and the follower spring abuts against the fitting groove.

[0013] Preferably, the side wall of the follower sleeve is provided with two sets of fixing springs, and each of the two sets of fixing springs is provided with a clamping plate, and a plurality of intermediate springs are installed between the two clamping plates.

[0014] Preferably, the lower end of the lifting sleeve is provided with a support plate, and the lower end of the relay body is attached to the support plate, and the two sides of the relay body are attached to two sets of clamps symmetrically arranged on both sides.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a cooling device for relay production, which has the following beneficial effects: This invention creatively introduces a flexible follow-up clamping mechanism with vertical buffering capability, fundamentally solving the problem of products falling due to collisions during cooling and conveying. The clamping plate in the follow-up mechanism forms a stable and gentle clamping of the relay under the action of the fixed spring and the intermediate spring. At the same time, the follow-up sleeve is slidably connected to the fitting groove on the lifting sleeve through the fitting rod and is provided with a reset elastic force by the follow-up spring. When adjacent relays interfere or collide, the impact force will push the follow-up sleeve and the clamped relay to generate relative displacement in the vertical direction and compress the follow-up spring, thereby absorbing and buffering the impact energy. The height of the lifting sleeve, which determines the conveying path, is not affected by this buffering movement, thus achieving decoupling between the collision response and the core conveying movement, limiting the maximum interference force to a controllable range, and ensuring the clamping stability of the relay in the dynamic cooling environment.

[0016] This invention achieves reliable vertical lifting and precise depth control during the relay immersion cooling process through a sophisticated mechanical linkage design. Its telescopic component uses upper and lower belts to drive the fixed sleeve and lifting sleeve respectively, and achieves relative movement and air pressure balance through the telescopic sleeve and air duct structure between them, allowing the relay to be smoothly immersed in water and lifted. The adjustment component guides the movement trajectory of the follower rod through a locally deformable adjustment belt, and the shape of the adjustment belt can be finely adjusted by pushing the top block with the middle bolt, thereby steplessly changing the immersion depth of the relay. This purely mechanical depth adjustment method has a simple structure, intuitive response, and is stable and reliable, and can flexibly adapt to the process requirements of different specifications of relays or different cooling intensities.

[0017] This equipment enhances safety and process adaptability while ensuring high-efficiency and continuous production. Its conveyor mechanism adopts a dual-belt synchronous drive, which allows the relay feeding, clamping, cooling immersion, lifting and delivery processes to be automatically completed in a continuous cycle, greatly improving the cycle time and automation level of the cooling process. The reliable anti-drop mechanism effectively avoids production line blockage, equipment downtime or batch damage to products caused by product drops, reducing unplanned downtime and material loss, thereby significantly improving overall production efficiency and economic benefits.

[0018] The structural design of this invention demonstrates high reliability and environmental adaptability. All core motion and buffering functions are achieved through mechanical structures, eliminating the need for complex sensors or electronic control systems. It can operate stably for a long time in a cooling station environment filled with moisture and vibration. The air duct structure ensures that the air pressure inside the telescopic cavity is balanced with the external environment, making the lifting action smooth and avoiding the risk of seal jamming. At the same time, all major components are easy to disassemble and maintain, and vulnerable parts such as clamps can be replaced individually, thus effectively controlling the maintenance cost of the equipment throughout its entire life cycle.

[0024] Please see Figures 1 to 10 This embodiment provides a cooling device for relay production. The device aims to solve the problems of unstable fixing and product falling during the existing relay cooling process due to conveyor belt vibration, water flow impact, or collision between products. By integrating a conveyor mechanism with vertical lifting and buffering functions and a clamping mechanism with flexible follow-up capabilities, the device achieves stable, adaptive clamping and reliable water immersion cooling of relays during the cooling and conveying process, significantly improving production safety and continuity.

[0025] The relay production cooling equipment includes a fixed frame 11 and a relay body 12 to be cooled, as well as a conveying mechanism for conveying and controlling the immersion cooling process and a follow-up mechanism 41 for providing flexible clamping protection. The conveying mechanism is further composed of a telescopic component 21 for vertical lifting and a regulating component 31 for adjusting the immersion depth.

[0026] The telescopic assembly 21 includes two side frames 22 symmetrically fixed on both sides of the frame 11. Each side frame 22 has an upper belt 23 and a lower belt 24 rotatably connected to its upper and lower ends, respectively. Multiple full-coverage sleeves 25 are fixed at equal intervals on the outer side wall of the upper belt 23, and multiple half-coverage sleeves 26 are fixed at equal intervals on the outer side wall of the lower belt 24. A fixed sleeve 27 is fixedly installed inside each full-coverage sleeve 25, and a lifting sleeve 28 is slidably connected to each half-coverage sleeve 26. A telescopic sleeve 29 is coaxially fixed at the lower end of the fixed sleeve 27. The telescopic sleeve 29 is slidably sleeved inside the lifting sleeve 28. An air guide pipe 210 is coaxially arranged inside the lifting sleeve 28. The lower end of the air guide pipe 210 is connected to the outside atmosphere, and its upper end is connected to the inner top surface of the telescopic sleeve 29 through a compression spring 211. A motor 212 is fixed on the side frame 22. The motor 212 drives the transmission wheels 213 that mesh with the upper belt 23 and the lower belt 24 to rotate through the transmission belt 214.

[0027] The adjustment assembly 31 includes a fixed plate 32 fixed inside the side frame 22. An adjustment belt 34 is tensioned at both ends of the fixed plate 32 via a rotating shaft 33. A follower rod 35 is fixed on the lifting sleeve 28. The end of the follower rod 35 rolls against the lower surface of the adjustment belt 34. Each rotating shaft 33 is provided with a tension spring 36 to provide rotational tension. An extension plate 37 is fixed to the side wall of the fixed plate 32. An intermediate bolt 38 is threaded onto the extension plate 37. A top block 39 that can be pushed by the intermediate bolt 38 is provided above the adjustment belt 34.

[0028] The follower mechanism 41 includes a follower sleeve 42 that is slidably sleeved outside the lifting sleeve 28. Two fitting rods 43 are fixed on the side wall of the follower sleeve 42. The lifting sleeve 28 is provided with a fitting groove 44 for the fitting rods 43 to slide. A follower spring 45 is provided between the end of the fitting rod 43 and the end of the fitting groove 44. The side wall of the follower sleeve 42 is connected to a clamping plate 47 by two sets of fixing springs 46. The two clamping plates 47 are connected to each other by multiple intermediate springs 48. A support plate 49 is fixed at the lower end of the lifting sleeve 28. The lower end of the relay body 12 is supported by the support plate 49, and its two sides are flexibly clamped by the two clamping plates 47.

[0029] The working process and core principle of the equipment are as follows: the starter motor 212 drives the upper belt 23 and lower belt 24 on both sides to run synchronously through the transmission system, and transports the relay body 12 to the work position between the two clamping plates 47. Under the thrust of the fixed spring 46, the two clamping plates 47 flexibly clamp the relay body 12, while its bottom is supported by the support plate 49, completing the feeding and initial clamping. Then the conveyor belt continues to move, driving the lifting sleeve 28 that clamps the relay body 12 to slide forward along the semi-enclosed sleeve 26.

[0030] When the follower rod 35 moves to contact the adjusting belt 34, it will move along the trajectory of the lower surface of the adjusting belt 34. If the adjusting belt 34 is preset to a concave profile, the follower rod 35 will drive the lifting sleeve 28 to slide downward relative to the fixed sleeve 27 fixed on the full-coverage sleeve 25, so that the lifting sleeve 28 and the relay body 12 held by it descend, while the telescopic sleeve 29 maintains a constant relative height. At this time, the telescopic sleeve 29 and the lifting sleeve 28 undergo relative displacement, the compression spring 211 is compressed, and the lower end of the air duct 210 is always connected to the atmosphere, ensuring the air pressure balance inside the telescopic cavity. The relay body 12 is thus steadily immersed in the water pool 13 for cooling. After the immersion cooling is completed, the follower rod 35 disengages from the concave section of the adjusting belt 34. Under the restoring force of the compression spring 211, the lifting sleeve 28 drives the relay body 12 to rise and reset, leaving the water surface, thus completing one cycle of immersion cooling and continuing to transport forward.

[0031] By turning the intermediate bolt 38, the position of the top block 39 can be changed, thereby locally raising or relaxing a specific section of the adjustment band 34, which in turn changes the concave depth of the follower rod 35 trajectory, realizing stepless adjustment of the water immersion cooling depth of the relay body 12 to adapt to different process requirements.

[0032] During the conveying process, if adjacent relay bodies 12 collide unexpectedly, the lower relay body 12 will be pushed upwards. This force will be transmitted to the follower sleeve 42 through the support plate 49, pushing the follower sleeve 42 to slide upwards along the fitting groove 44 via the fitting rod 43 and compress the follower spring 45. The height of the lifting sleeve 28 itself is determined by the mechanical linkage between the conveyor belt and the adjusting belt 34 and remains basically unchanged. This achieves vertical decoupling between the collision force and the conveying path. This design limits the maximum interference impact force to the pre-tightening elasticity range of the follower spring 45, avoiding clamping failure and product drop caused by hard collisions, and ensuring the safety and stability of the conveying process.

[0033] Working principle summary: This invention achieves vertical lifting and lowering of the relay for water immersion cooling through the relative movement of the lifting sleeve 28 and the fixed sleeve 27 driven by the belt. The immersion depth is flexibly controlled by the adjusting belt 34 mechanism. Innovatively, a buffer mechanism composed of the follower sleeve 42 and the follower spring 45 is introduced, which enables the clamping station to undergo relative displacement and absorb impact energy when subjected to vertical collision. Thus, while ensuring continuous and reliable cooling, it effectively prevents the risk of falling due to product interference.

For all the fixed connections mentioned above, welding is preferred.
