Description

Technical Field

[0001] This utility model relates to the field of relay assembly technology, specifically to a relay base magnetic circuit assembly machine. Background Technology

[0002] In the field of modern electronic control technology, relays, as a key electronic control device, are widely used in various automatic control circuit systems. A relay comprises two main parts: the magnetic circuit assembly and the contact assembly. The magnetic circuit assembly, typically composed of a coil, iron core, and yoke, is responsible for generating electromagnetic attraction to drive the contacts. The contact assembly, containing key components such as stationary springs and contacts, is the core actuator for controlling the on / off state of the circuit.

[0003] In traditional relay assembly processes, the assembly of contact components is primarily done manually. The specific steps are as follows: First, operators rely on experience and feel to precisely insert the contacts into the rivet holes of the stationary spring, then rivet the contacts to secure them to the spring. This process demands a high level of skill and concentration from the operator; even slight errors can lead to contact misalignment or insecure riveting. Next, the riveted stationary spring is manually inserted into the base again, and then riveted to secure it to the base, completing the contact assembly. Finally, the pre-assembled magnetic circuit assembly is precisely aligned with the contact assembly and placed on a riveting machine for the final riveting process.

[0004] However, manual assembly has many drawbacks. On the one hand, manual assembly is inefficient and cannot meet the needs of large-scale production. On the other hand, due to differences in operator skill level, fatigue, and subjective judgment, problems such as misalignment of the riveting position between the contacts and the stationary spring, and uneven contact pressure are prone to occur during manual assembly, thus affecting the quality of relay products.

[0005] In view of the above problems, it is particularly necessary to develop a device that can realize the automatic assembly of the magnetic circuit of the relay base. Utility Model Content

[0046] 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.

[0047] This utility model provides a relay base magnetic circuit assembly machine to solve the problems of how to automatically assemble contact components and how to automatically assemble contact components and magnetic circuit components.

[0048] See Figure 1 As shown, Figure 1 The image shown is a top view of the relay base magnetic circuit assembly machine in the embodiment. The relay base magnetic circuit assembly machine includes a frame 1, a first conveyor line 2, a second conveyor line 3, a stationary spring feeding device 4, a contact feeding device 5, a riveting device 6, a base feeding device 7, a first assembly device 8, and a second assembly device 9.

[0049] Both the first conveyor line 2 and the second conveyor line 3 are mounted on the frame 1. The first conveyor line 2 has several first fixtures 21, which are used to transport the first fixtures 21. The first fixtures 21 are used to place and limit the stationary spring a. The second conveyor line 3 has several second fixtures 31, which are used to transport the second fixtures 31. The second fixtures 31 are used to place and limit the base c.

[0050] The static spring feeding device 4, the contact feeding device 5, and the riveting device 6 are all installed on the frame 1 and arranged sequentially along the conveying direction of the first conveyor line 2.

[0051] The base feeding device 7, the first assembly device 8, and the second assembly device 9 are all installed on the frame 1 and arranged sequentially along the conveying direction of the second conveyor line 3.

[0052] The device includes: a stationary spring feeding device 4 for transferring stationary spring a to the first fixture 21; a contact feeding device 5 for transferring contact b and inserting it into the rivet hole of stationary spring a on the first fixture 21; a riveting device 6 for pressing and fixing contact b and stationary spring a into one piece; a base feeding device 7 for transferring base c to the second fixture 31; a first assembly device 8 for transferring stationary spring a with contact b riveted to it and riveting it to base c on the second fixture 31 to form a contact assembly; and a second assembly device 9 for transferring magnetic circuit assembly d and riveting it to the contact assembly on the second fixture 31 to form a product.

[0053] When using the relay base magnetic circuit assembly machine of the above technical solution, firstly, the stationary spring sheet feeding device 4 transfers the stationary spring sheets a one by one to each of the first fixtures 21 on the first conveyor line 2, with each first fixture 21 holding two stationary spring sheets a; then, the first conveyor line 2 conveys the first fixture 21 to the contact feeding device 5 in the direction of the arrow, and the contact feeding device 5 transfers the contacts b and inserts them into the rivet holes of each stationary spring sheet a in the first fixture 21; then, the first conveyor line 2 conveys the first fixture 21 to the riveting device 6 in the direction of the arrow, and the riveting device 6 further rivets the contacts b into the rivet holes of the stationary spring sheets a, thereby pressing and fixing the contacts b and the stationary spring sheets a into one piece, while the base is fed. Device 7 transfers the base c one by one to the second fixtures 31 on the second conveyor line 3 in the direction of the arrow; then, the first conveyor line 2 conveys the first fixture 21 to the first assembly device 8 in the direction of the arrow, while the second conveyor line 3 conveys the second fixture 31 to the first assembly device 8 in the direction of the arrow. The first assembly device 8 transfers the stationary spring a of the first fixture 21 and rivets it to the base c of the second fixture 31 to form a contact assembly; finally, the second conveyor line 3 conveys the second fixture 31 to the second assembly device 9 in the direction of the arrow, and the second assembly device 9 transfers the magnetic circuit assembly d in the direction of the arrow and rivets it to the contact assembly of the second fixture 31 to form the desired product. It can be seen that the relay base magnetic circuit assembly machine can automatically feed, assemble, and rivet the stationary spring a, contact b, and base c, thereby automatically assembling the contact assembly. It can also automatically rivet and assemble the contact assembly and magnetic circuit assembly d to form the required product, replacing manual assembly. This significantly improves the assembly efficiency and quality stability of relays, solves the efficiency and quality problems caused by manual assembly, reduces labor intensity, and promotes the relay industry towards intelligent and automated development.

[0054] See Figure 1 As shown, based on the above embodiment, there are two stationary reed feeding devices 4. The two stationary reed feeding devices 4 are arranged at intervals along the conveying direction of the first conveyor line 2. The two stationary reed feeding devices 4 are respectively used to transfer two different types or specifications of stationary reeds a onto the first fixture 21. In this way, the relay base magnetic circuit assembly machine can feed and assemble two different types or specifications of stationary reeds a, effectively improving its adaptability.

[0055] See Figure 1 and Figure 2 As shown, Figure 2This is a perspective view of the first conveyor line, the stationary spring feeding device, the contact feeding device, and the riveting device in the embodiment. In one embodiment of the stationary spring feeding device 4, the stationary spring feeding device 4 includes a stationary spring vibratory plate 41, a limiting mechanism 42, a docking mechanism 43, and a stationary spring transfer mechanism 44. The stationary spring vibratory plate 41 is mounted on the frame 1 and is used to continuously feed stationary springs a one by one. The limiting mechanism 42 is mounted on the discharge end of the stationary spring vibratory plate 41 and is used to align the last stationary spring a at the discharge end of the stationary spring vibratory plate 41 and block the output of other stationary springs a. The docking mechanism 43 is mounted on the frame 1 and is positioned opposite to the discharge end of the stationary spring vibratory plate 41. The docking mechanism 43 is used to receive the stationary springs a fed by the stationary spring vibratory plate 41 and transfer the stationary springs a to the stationary spring transfer mechanism 44. The stationary spring transfer mechanism 44 is mounted on the frame 1 to receive the stationary spring a transferred by the docking mechanism 43 and transfer the stationary spring a to the first fixture 21. Thus, when the stationary spring a is being fed, firstly, the stationary spring vibrating plate 41 continuously outputs the stationary spring a one by one, while the limiting mechanism 42 aligns the stationary spring a at the very end of the output end of the stationary spring vibrating plate 41, so that the stationary spring vibrating plate 41 inputs the aligned stationary spring a into the docking mechanism 43, and prevents other stationary spring a at the output end of the stationary spring vibrating plate 41 from being output; then, the docking mechanism 43 receives the aligned stationary spring a and transfers it to the stationary spring transfer mechanism 44; finally, the stationary spring transfer mechanism 44 places the stationary spring a on the first fixture 21, thereby achieving automatic feeding of the stationary spring a.

[0056] The aforementioned static reed vibratory feeder 41 can use an existing vibratory feeder. The aforementioned static reed transfer mechanism 44 can use an existing two-axis linear drive mechanism, three-axis linear drive mechanism, or robot, with a clamping cylinder installed at its output end. In this way, the clamping cylinder, in cooperation with the two-axis linear drive mechanism, three-axis linear drive mechanism, or robot, can clamp the static reed a and transfer the static reed a to any of the first fixtures 21 on the first conveyor line 2.

[0057] See Figure 2 and Figure 3 As shown, Figure 3 for Figure 2 The enlarged schematic diagram at point A shows that the aforementioned limiting mechanism 42 can be formed by combining the existing telescopic cylinder 433 or telescopic electric rod and other linear drive mechanisms with the limiting rod 421. By inserting the limiting rod 421 into the discharge end of the static spring vibrating plate 41, it plays the role of straightening and blocking.

[0058] See Figure 2 and Figure 3As shown, the docking mechanism 43 can be formed by combining existing clamps 431, rotary cylinders 432 and telescopic cylinders 433. The clamps 431 and telescopic cylinders 433 cooperate to clamp the last static spring a at the discharge end of the static spring vibrating plate 41 and pull the static spring a out of the discharge end of the static spring vibrating plate 41. The rotary cylinder 432 can rotate the static spring a to the static spring transfer mechanism 44 located on one side of the telescopic cylinder 433.

[0059] See Figure 1 and Figure 2 As shown, in one embodiment of the contact feeding device 5, the contact feeding device 5 includes a contact vibratory feeder 51, an adsorption mechanism 52, and a contact transfer mechanism 53. The contact vibratory feeder 51 is mounted on the frame 1 and is used to continuously convey contacts b. The adsorption mechanism 52 is used to adsorb or release contacts b. The contact transfer mechanism 53 is mounted on the frame 1, and the output end of the contact transfer mechanism 53 is connected to the adsorption mechanism 52 by means of screwing or welding. The contact transfer mechanism 53 is used to drive the adsorption mechanism 52 to reciprocate between the contact vibratory feeder 51 and the first conveyor line 2. Thus, when contact b is being fed, firstly, the contact vibrating plate 51 continuously outputs contact b. Then, the contact transfer mechanism 53 drives the adsorption mechanism 52 to move to the discharge end of the contact vibrating plate 51, and the adsorption mechanism 52 adsorbs the last contact b at the discharge end of the contact vibrating plate 51. Finally, the contact transfer mechanism 53 drives the adsorption mechanism 52 to move to a first fixture 21 on the first conveyor line 2, so as to transfer the contact b and insert it into the stationary spring a of the first fixture 21, thereby realizing automatic feeding of contact b.

[0060] The aforementioned contact vibratory feeder 51 can use an existing vibratory feeder. The aforementioned contact transfer mechanism 53 can use an existing two-axis linear drive mechanism, a three-axis linear drive mechanism, or a robotic arm, and the aforementioned adsorption mechanism 52 can use an existing vacuum adsorption mechanism 52. In this way, the two work together to transfer the contact b at the discharge end of the contact vibratory feeder 51 to any of the first fixtures 21 on the first conveyor line 2.

[0061] See Figure 1 and Figure 4 As shown, Figure 4This is a partial structural diagram of the second conveyor line and the base loading device in one embodiment. In one implementation of the base loading device 7, the base loading device 7 includes a base vibratory feeder 71, a material distribution mechanism 72, and a base transfer mechanism 73. The base vibratory feeder 71 is mounted on the frame 1 and is used to continuously convey bases c one by one. The material distribution mechanism 72 includes a slider 721 and a slider drive 722. The slider 721 is slidably connected to the frame 1 in a direction perpendicular to the discharge direction of the base vibratory feeder 71. The slider 721 has a receiving groove 7211 for accommodating and limiting a single base c. The slider drive 722 is mounted on the frame 1 by screwing or welding and is drively connected to the slider 721. The slider drive 722 is used to drive the slider 721 to reciprocate between a first position and a second position. The base transfer mechanism 73 is mounted on the frame 1 and is used to transfer the base c at the second position to the second fixture 31. When the slider 721 is in the first position, the receiving groove 7211 is opposite to and connected to the discharge end of the base vibrating disk 71, and the base vibrating disk 71 transports the base c into the receiving groove 7211; when the slider 721 is in the second position, the receiving groove 7211 is offset from the discharge end of the base vibrating disk 71, and the slider 721 blocks the discharge end of the base vibrating disk 71. Thus, when the base c is fed, the slider 721 is initially in the first position. First, the base vibrating plate 71 feeds the base c into the receiving groove 7211. Then, the slider drive 722 drives the slider 721 to move to the second position. The slider 721 blocks the discharge end of the base vibrating plate 71 to prevent other base cs from being output from the discharge end of the base vibrating plate 71. At the same time, the base c in the receiving groove 7211 is moved to the base transfer mechanism 73. Finally, the base transfer mechanism 73 clamps the base c in the receiving groove 7211 and transfers it to any of the second fixtures 31 on the second conveyor line 3, thereby realizing automatic feeding of the base c.

[0062] The aforementioned base vibratory feeder 71 can use an existing vibratory feeder. The aforementioned slider drive 722 can use an existing telescopic cylinder 433 or telescopic rod, etc., linear drive mechanism, and its output end is connected to the slider 721 by screwing or welding. The aforementioned base transfer mechanism 73 can use an existing two-axis linear drive mechanism, three-axis linear drive mechanism, or robot, and its output end is equipped with a clamping cylinder. In this way, the clamping cylinder, in cooperation with the two-axis linear drive mechanism, three-axis linear drive mechanism, or robot, can clamp the base c and transfer the base c to any of the second fixtures 31 on the second conveyor line 3.

[0063] See Figure 1 and Figure 2As shown, in one embodiment of the first conveyor line 2, the first conveyor line 2 is a divider, and at least five first fixtures 21 are distributed in a ring at intervals on the divider. There are two riveting devices 6. A stationary spring feeding device 4, a contact feeding device 5, two riveting devices 6, and a first assembly device 8 are sequentially installed on the outside of the divider, and each of these devices is positioned opposite to one of the first fixtures 21. Thus, each rotation of the divider allows for the transfer of the workpiece between two adjacent devices, facilitating continuous assembly. Furthermore, the stationary spring a and contact b are riveted twice by the two riveting devices 6, effectively ensuring the riveting effect.

[0064] The aforementioned divider can be an existing divider. The aforementioned riveting device 6 can be an existing riveting machine.

[0065] In addition to the above-described embodiments, the first conveyor line 2 can also employ any one of the existing pushing mechanisms, conveyor belts, or shifting fork mechanisms, either individually or in combination, to provide driving force, thereby achieving the function of conveying the first fixture 21. Similarly, the second conveyor line 3 can also employ any one of the existing pushing mechanisms, conveyor belts, or shifting fork mechanisms, either individually or in combination, to provide driving force, thereby achieving the function of conveying the second fixture 31.

[0066] See Figure 1 and Figure 4 As shown, based on any of the above embodiments, the relay base magnetic circuit assembly machine further includes a base preheating device 32. The base preheating device 32 is mounted on the frame 1 and located between the base feeding device 7 and the first assembly device 8. The base preheating device 32 is used to heat the base c. Thus, after the base c is fed, the base preheating device 32 heats the base c on the second conveyor line 3 before assembly, which facilitates the smooth riveting of the stationary spring a onto the base c.

[0067] See Figure 1As shown, in one embodiment of the first assembly device 8 and the second assembly device 9, the first assembly device 8 includes a first transfer mechanism 81 and a first riveting mechanism 82. The first transfer mechanism 81 is located downstream of the base preheating device 32 and is used to transfer the stationary spring a riveted with contact b and insert it into the base c of the second fixture 31. The first riveting mechanism 82 is located downstream of the first transfer mechanism 81 and is used to press and fix the stationary spring a and the base c into one piece to form a contact assembly. The second assembly device 9 includes a second transfer mechanism 91 and a second riveting mechanism 92. The second transfer mechanism 91 is located downstream of the first riveting mechanism 82 and is used to transfer the magnetic circuit assembly d and insert it into the contact assembly of the second fixture 31. The second riveting mechanism 92 is located downstream of the second transfer mechanism 91 and is used to press and fix the magnetic circuit assembly d and the contact assembly into one piece to form a product. It can be seen that the first assembly device 8 and the second assembly device 9 can be accurately assembled by the transfer mechanism, and then the riveting mechanism will further rivet the static spring a or the magnetic circuit assembly d into the base c, thereby pressing and fixing them into one piece. This can effectively ensure the riveting effect.

[0068] The first riveting mechanism 82 and the second riveting mechanism 92 mentioned above can both use existing riveting presses, which can perform both riveting and shaping functions, avoiding the situation where the workpiece is not in dimensional standard due to riveting force, thereby further improving product quality.

[0069] Downstream of the first riveting mechanism 82 and the second riveting mechanism 92, a chip removal mechanism 33 can be installed to blow away dust from the surface of the riveted components, thereby further improving the installation quality of the product.

[0070] See Figure 1 and Figure 2As shown, based on any of the above embodiments, the relay base magnetic circuit assembly machine further includes a positioning detection device 22 and a first visual inspection device 23. The positioning detection device 22 is installed between the contact feeding device 5 and the riveting device 6, and is used to detect whether the contact b is inserted into the rivet hole of the stationary spring a. The first visual inspection device 23 is installed between the riveting device 6 and the first assembly device 8, and is used to detect the riveting status of the stationary spring a and the contact b. Thus, after the contact feeding device 5 feeds the contact b and inserts it into the rivet hole of the stationary spring a, the first conveyor line 2 conveys the stationary spring a with the inserted contact b to the positioning detection device 22, which confirms whether the contact b is inserted correctly. After confirmation, the first conveyor line 2 then conveys the stationary spring a with the inserted contact b to the riveting device 6 for riveting. After riveting, the first conveyor line 2 conveys the stationary spring a with the riveted contact b to the first visual inspection device 23. The first visual inspection device 23 detects the riveting condition of the stationary spring a and the contact b. Finally, the first conveyor line 2 transports the stationary spring a with the contact b riveted to the first assembly device 8. The first assembly device 8 sorts the good and defective products according to the detection results of the first visual inspection device 23, and transports the good and defective products separately. The good products can be transferred to the base c of the second fixture 31, while the defective products can be placed in the defective product box or other locations for easy recycling or rework. It can be seen that the arrival detection device 22 can not only effectively avoid missing parts that affect the product's functionality, but also effectively avoid incorrect assembly. In conjunction with the first visual inspection device 23, it can play a role in classifying and unloading materials, thereby further improving the yield rate.

[0071] The aforementioned positioning detection device 22 can use existing positioning detection mechanisms such as infrared sensors or proximity switches. The aforementioned first vision detection device 23 can use existing vision detection mechanisms such as CCDs.

[0072] See Figure 1 As shown, based on the above embodiment, the relay base magnetic circuit assembly machine further includes a second visual inspection device 34 and a defective product unloading device 35. The second visual inspection device 34 is installed downstream of the second assembly device 9 and is used to detect the riveting condition of the magnetic circuit assembly d and the contact assembly. The defective product unloading device 35 is installed downstream of the second visual inspection device 34 and is used to remove unqualified products from the second conveyor line 3 based on the detection results of the second visual inspection device 34.
