Description

Technical Field

[0001] This utility model relates to the field of magnetic latching relay manufacturing technology, specifically to a dust removal device for magnetic latching relays. Background Technology

[0002] In the manufacturing process of magnetic latching relays, dust removal is a crucial step in ensuring product quality and lifespan. The internal structure of a magnetic latching relay is delicate; even tiny dust particles that penetrate through gaps or openings can cause poor contact, decreased insulation performance, and consequently affect the relay's overall performance and reliability, shortening its lifespan. Therefore, efficient and comprehensive dust removal is of paramount importance for magnetic latching relays.

[0003] However, the relay dust removal devices commonly used in the industry currently have significant design limitations. These devices typically consist of a fixed fixture and a dust-blowing mechanism located directly above it. In use, the magnetically latched relay is placed on the fixture, and then the dust-blowing mechanism is activated, blowing high-pressure airflow from above the relay to remove dust from its surface. However, this fixed-position dust-blowing method, due to its unidirectional and non-adjustable blowing direction, can only effectively remove dust from the top surface of the relay. The sides of the relay, especially hidden areas such as side channels and gaps, are difficult to clean thoroughly because the airflow cannot directly reach them. The cleanliness of the side channels, as an important part of the relay's internal structure, directly affects the relay's performance and reliability. If dust accumulates in these channels, it will severely affect the relay's heat dissipation performance and electrical connection stability.

[0004] In view of the above-mentioned shortcomings in the existing technology, it is necessary to develop a magnetic latching relay dust removal device that can flexibly adjust the blowing direction. Utility Model Content

[0006] This invention provides a dust removal device using a magnetic latching relay, which at least solves the technical problem of how to adjust the blowing direction to improve the dust removal effect.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust removal device for a magnetic latching relay, comprising:

[0009] A fixed frame and a rotating frame, with the rotating frame rotatably mounted on the fixed frame;

[0010] The fixture, mounted on a rotating frame, is used to place and position the magnetic latching relay;

[0011] The soot blowing mechanism is mounted on a fixed frame and positioned opposite to the tooling. The soot blowing mechanism is used to blow soot and remove dust from the magnetic latching relay on the tooling.

[0012] The rotating mechanism is mounted on the fixed frame and is connected to the rotating frame via a transmission. The rotating mechanism is used to drive the rotating frame to rotate, thereby causing the tooling and its magnetic latching relay to rotate relative to the soot blowing mechanism.

[0013] Further, the aforementioned rotating frame includes a slide rail and a pressure plate. The tooling includes a base plate that is slidably connected to the slide rail. The pressure plate is used to press against the magnetic latching relay on the tooling. The fixed frame is provided with a feeding channel and a discharging channel that are opposite to the position of the slide rail. The feeding channel and the discharging channel are respectively located on both sides of the rotating frame. The feeding channel is used for the tooling to pass through and enter the rotating frame, and the discharging channel is used for the tooling to pass through and exit the rotating frame.

[0014] Furthermore, the aforementioned rotating frame is equipped with at least two soot blowing stations, each station being used to accommodate a single tool. The number of soot blowing mechanisms is the same as the number of soot blowing stations and they are set up in a one-to-one correspondence.

[0015] Furthermore, the number of the aforementioned pressure plates is the same as the number of soot blowing stations and they are set one by one. The bottom of the pressure plate is provided with a guide surface, which extends downward at an angle from the feeding channel.

[0016] Further, the aforementioned soot blowing mechanism includes a soot suction hood and a soot blowing pipe. The soot suction hood is slidably mounted on a fixed frame along the vertical direction, and the soot blowing pipe is fixed inside the soot suction hood.

[0017] The dust removal device of the magnetic latching relay also includes a lifting mechanism, which is mounted on a fixed frame. The output end of the lifting mechanism is connected to each dust suction hood, and the lifting mechanism is used to drive each dust suction hood to move up and down toward the corresponding dust blowing station.

[0018] Further, the aforementioned rotating mechanism includes a rotating drive component, a driving gear, and a ring-shaped driven gear. The rotating drive component is mounted on a fixed frame, the driving gear is mounted on the output end of the rotating drive component, and the driven gear is rotatably mounted on the fixed frame and meshes with the driving gear. The inner diameter of the driven gear is not less than the dimensions of the feed channel and the discharge channel.

[0019] The rotating frame also includes a connecting plate, one end of which is eccentrically fixed to the driven gear, and the other end is fixed to the slide rail.

[0020] Further, the aforementioned tooling includes a limiting seat, a swing block, and an elastic element. The limiting seat is provided with a limiting groove for accommodating and limiting the main body of the magnetic latching relay. The swing block is rotatably mounted on the limiting seat. The two ends of the elastic element are respectively connected to one end of the swing block and the limiting seat. The elastic element has a spring force that drives the free end of the swing block to rotate toward the limiting groove.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the dust removal device for a magnetic latching relay provided by this utility model has the following beneficial effects:

[0023] When using the dust removal device for the magnetic latching relay provided by this utility model, firstly, the magnetic latching relay is placed on the fixture; then, the dust blowing mechanism and the rotating mechanism are activated. The dust blowing mechanism blows dust off the magnetic latching relay on the fixture, while the rotating mechanism drives the fixture and the magnetic latching relay on it to rotate at multiple angles relative to the dust blowing mechanism, so that the dust blowing mechanism can remove dust from the top and sides of the magnetic latching relay. It can be seen that, compared with the prior art, this utility model achieves flexible adjustment of the dust blowing direction through the coordinated work of the rotating and dust blowing mechanisms. This allows the dust blowing mechanism to perform dust blowing operations on the magnetic latching relay on the fixture from multiple angles, ensuring that the top and sides of the magnetic latching relay, especially the hidden parts such as side holes and gaps, are effectively cleaned, thereby effectively improving the dust removal effect on the magnetic latching relay.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This invention provides a dust removal device using a magnetic latching relay, which addresses the problem of adjusting the blowing direction to improve dust removal efficiency.

[0037] See Figure 1 As shown, Figure 1 The dust removal device of the magnetic latching relay in the embodiment is shown in a first-view perspective. The dust removal device of the magnetic latching relay includes a fixed frame 1, a rotating frame 2, a tooling 3, a dust blowing mechanism 4, and a rotating mechanism 5.

[0038] The rotating frame 2 is rotatably connected to the fixed frame 1.

[0039] Tooling 3 is located on rotating frame 2 and is used to place and position magnetic latching relay 6.

[0040] The soot blowing mechanism 4 is connected to the fixed frame 1 and is positioned opposite to the tooling 3. The soot blowing mechanism 4 is used to blow soot and remove dust from the magnetic latching relay 6 on the tooling 3.

[0041] The rotating mechanism 5 is mounted on the fixed frame 1 and is connected to the rotating frame 2 via a transmission. The rotating mechanism 5 is used to drive the rotating frame 2 to rotate, thereby causing the tooling 3 and its magnetic latching relay 6 to rotate relative to the soot blowing mechanism 4.

[0042] When using the dust removal device for the magnetic latching relay described above, firstly, the magnetic latching relay 6 is placed on the fixture 3; then, the blowing mechanism 4 and the rotating mechanism 5 are activated. The blowing mechanism 4 blows dust off the magnetic latching relay 6 on the fixture 3, while the rotating mechanism 5 drives the fixture 3 and the magnetic latching relay 6 on it to rotate at multiple angles relative to the blowing mechanism 4, so that the blowing mechanism 4 can remove dust from the top and sides of the magnetic latching relay 6. It can be seen that, compared with the prior art, this utility model, through the coordinated work of the rotating mechanism 5 and the blowing mechanism 4, achieves flexible adjustment of the blowing direction, enabling the blowing mechanism 4 to perform dust removal operations on the magnetic latching relay 6 on the fixture 3 from multiple angles, ensuring that the top and sides of the magnetic latching relay 6, especially the hidden parts such as side holes and gaps, are effectively cleaned, thereby effectively improving the dust removal effect on the magnetic latching relay 6.

[0043] See Figure 1 , Figure 2and Figure 4 As shown, Figure 2 This is a schematic diagram of the rotating frame and tooling in the embodiment. Figure 4 This is a perspective view of the dust removal device for the magnetic latching relay in the embodiment, taken from a second-angle perspective. Based on the above embodiment, the rotating frame 2 includes a slide rail 21 and a pressure plate 22. The tooling 3 includes a base plate 31 slidably connected to the slide rail 21. The pressure plate 22 is used to press against the magnetic latching relay 6 on the tooling 3. The fixed frame 1 has a feed channel 11 and a discharge channel 12 opposite to the slide rail 21. The feed channel 11 and the discharge channel 12 are located on opposite sides of the rotating frame 2. The feed channel 11 allows the tooling 3 to pass through and enter the rotating frame 2. The discharge channel 12 allows the tooling 3 to pass through and exit the rotating frame 2. Thus, before dust removal, the tooling 3 can be fed into the rotating frame 2 via the feeding channel 11 through an external conveying mechanism for dust removal. After dust removal, the tooling 3 can slide along the rotating frame 2 into the discharge channel 12 under the pushing action of the next tooling 3 fed into the rotating frame 2. The tooling 3 fed into the discharge channel 12 can then be fed into the next process through an external conveying mechanism, thereby realizing automatic input and output of the tooling 3, saving manual handling, and improving the production efficiency of the magnetic latching relay 6. In addition, when the tooling 3 slides under the pressure plate 22, the pressure plate 22 abuts against the magnetic latching relay 6 on the tooling 3. When the tooling 3 is not pushed by the external conveying mechanism, the pressure plate 22 can fasten the tooling 3 and the magnetic latching relay 6 on it together to the rotating frame 2, effectively ensuring the stability of the magnetic latching relay 6 during the dust removal process and preventing it from shifting due to vibration, thereby ensuring the dust removal effect.

[0044] See Figure 1 , Figure 2 and Figure 4 As shown, based on the above embodiment, the rotating frame 2 is provided with at least two dust-blowing stations 23, each dust-blowing station 23 for accommodating a single tooling 3. The number of dust-blowing mechanisms 4 is the same as the number of dust-blowing stations 23 and is arranged in a one-to-one correspondence. Thus, by setting multiple dust-blowing stations 23 and corresponding dust-blowing mechanisms 4, this invention can achieve simultaneous dust removal for multiple magnetic latching relays 6, further improving the batch production efficiency of the magnetic latching relays 6. In this embodiment, the rotating frame 2 has four dust-blowing stations 23.

[0045] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 for Figure 2The enlarged schematic diagram at point A shows that, based on the above embodiment, the number of pressure plates 22 is the same as the number of soot blowing stations 23, and they are arranged in a one-to-one correspondence. The bottom of the pressure plate 22 has a guide surface 221, which extends downward at an angle from the feed channel 11. In this way, when the tooling 3 enters the soot blowing station 23, the guide surface 221 allows the tooling 3 and the magnetic latching relay 6 on it to move smoothly under the pressure plate 22 and abut tightly against the bottom surface of the pressure plate 22. This helps to reduce friction and collision of the tooling 3 during the input process, protecting the safety of the tooling 3 and the magnetic latching relay 6.

[0046] See Figure 1 and Figure 4 As shown, in one embodiment of the dust-blowing mechanism 4, the dust-blowing mechanism 4 includes a dust-collecting hood 41 and a dust-blowing pipe 42. The dust-collecting hood 41 is slidably connected to the fixed frame 1 vertically. The dust-blowing pipe 42 is fixed inside the dust-collecting hood 41 by means of screwing or welding. The dust removal device of the magnetic latching relay also includes a lifting mechanism 7. The lifting mechanism 7 is installed on the fixed frame 1 by means of screwing or welding, and the output end of the lifting mechanism 7 is connected to each dust-collecting hood 41 by means of screwing or welding. The lifting mechanism 7 is used to drive each dust-collecting hood 41 to move up and down toward the corresponding dust-blowing station 23. Thus, during the dust blowing process, firstly, the lifting mechanism 7 drives the dust suction hood 41 to descend and cover the corresponding dust blowing station 23 of the rotating frame 2, forming a closed dust blowing space. Subsequently, the dust blowing pipe 42 blows away the dust on the magnetic latching relay 6 in the corresponding dust blowing space. At the same time, the dust suction hood 41 can suck the blown-down dust out of the dust blowing space and collect it through an external suction device. This can effectively prevent dust from spreading to the surrounding environment, protect the cleanliness of the production environment, and facilitate subsequent unified cleaning.

[0047] The aforementioned lifting mechanism 7 can use existing linear drive mechanisms such as telescopic cylinders, motor-screw-nut linear modules, etc.

[0048] See Figure 1 and Figure 4As shown, in one embodiment of the rotating mechanism 5, the rotating mechanism 5 includes a rotating drive member 51, a driving gear 52, and a ring-shaped driven gear 53. The rotating drive member 51 is mounted on the fixed frame 1 by means of screwing or welding. The driving gear 52 is mounted on the output end of the rotating drive member 51 by means of welding or pin connection. The driven gear 53 is rotatably connected to the fixed frame 1 and meshes with the driving gear 52. The inner diameter of the driven gear 53 is not less than the size of the feed channel 11 and the discharge channel 12. The rotating frame 2 also includes a connecting plate 24, one end of which is eccentrically fixed to the driven gear 53, and the other end is fixed to the slide rail 21. Thus, the rotating drive member 51 drives the driving gear 52 to rotate, which in turn drives the driven gear 53 to rotate, thereby causing the rotating frame 2 and the tooling 3 on it to rotate together at multiple angles. In addition, the inner diameter design of the driven gear 53 ensures that the tooling 3 can be smoothly fed into the rotating frame 2 from the feed channel 11 and then into the discharge channel 12 from the rotating frame 2. The connecting plate 24 ensures that the rotating frame 2 is positioned relative to the feed channel 11 and the discharge channel 12.

[0049] See Figure 1 and Figure 4 As shown, there are two of each of the aforementioned driving gear 52, driven gear 53, and connecting plate 24, symmetrically located at both ends of the rotating frame 2, which enables the rotating frame 2 to rotate smoothly and reliably. The aforementioned rotary drive component 51 can use existing rotary drive mechanisms such as servo motors or servo motors.

[0050] See Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the tooling 3, the tooling 3 includes a limiting seat 32, a swing block 33, and an elastic element (not shown in the figure). The limiting seat 32 has a limiting groove 321 for accommodating and limiting the main body of the magnetic latching relay 6. The swing block 33 is rotatably connected to the limiting seat 32. The two ends of the elastic element are respectively connected to one end of the swing block 33 and the limiting seat 32. The elastic element has a spring force that drives the free end of the swing block 33 to rotate toward the limiting groove 321, so that the free end of the swing block 33 presses tightly against the main body of the magnetic latching relay 6, achieving a positioning effect. In this way, the setting of the limiting groove 321 achieves accurate limiting of the magnetic latching relay 6, and the combination of the swing block 33 and the elastic element achieves fixation of the magnetic latching relay 6, making the tooling 3 more convenient and efficient in loading and unloading the magnetic latching relay 6.
