Description

Technical Field

[0001] This utility model relates to the field of relay assembly technology, and in particular to a high-efficiency automatic hinge machine. Background Technology

[0002] In relays, the electromagnetic mechanism is indispensable. Within this mechanism, the yoke needs to be fitted with the iron core through a hinge process to form an integrated structure. However, in existing iron core hinge mechanisms, the manual riveting force varies during the hinge process. Consequently, the finished yoke may become twisted or deformed, and the surfaces of the two yokes may not be parallel. This ultimately leads to insufficient magnetic retention force in the magnetic circuit system, affecting the stability and safety of the relay product. Furthermore, this manual riveting method results in inconsistent product quality and low labor efficiency. Utility Model Content

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Please see Figure 1 and Figure 2This embodiment provides a high-efficiency automatic hinge machine, including a machine base 10. A product transverse movement mechanism 20 for conveying materials is arranged laterally on the machine base 10. Feeding rails 30 for conveying skeletons and discharging belts 40 for conveying finished products are arranged on the machine base 10 at both ends of the product transverse movement mechanism 20. An assembly table 50 is arranged below the product transverse movement mechanism 20, with its ends intersecting the feeding rails 30 and the discharging belts 40 respectively. The assembly table 50 is provided with several clamps for clamping skeletons along the conveying direction of the product transverse movement mechanism 20. On the machine base 10 on both sides of the product transverse movement mechanism 20 and along the conveying direction of the product transverse movement mechanism 20, there are yoke assembly stations for assembling yokes to skeletons and iron core assembly stations for assembling iron cores to skeletons.

[0024] In summary, during operation, the skeleton is placed on the feeding track 30, which then transports it to the product traversing mechanism 20. The product traversing mechanism 20 moves multiple skeletons from the feeding track 30 to the fixtures on the assembly table 50, with the fixtures corresponding to the core assembly station. The core assembly station installs the core onto the skeleton. After core installation, the product traversing mechanism 20 moves the skeleton to the yoke assembly station, where the yoke is assembled onto the skeleton. The skeleton is then moved to the riveting position of the core assembly station on the assembly table 50 for riveting. Two vision inspection mechanisms 150 are installed on the machine base 10 at the end of the assembly table 50, near the discharge belt 40. The visual inspection mechanism 150 is located on both sides of the assembly table 50 via a lateral movement module. The visual inspection mechanism 150 can effectively detect whether there are any problems with several products being assembled at the same time by moving back and forth. After the inspection is completed, the product lateral movement mechanism 20 moves the finished product from the assembly table 50 to the discharge belt 40 for conveying. In addition, a demagnetizing mechanism 140 for eliminating the magnetism on the finished product is set on the discharge belt 40. The demagnetizing mechanism 140 adopts a demagnetizer, which can eliminate the magnetism on the finished product. The above-mentioned automation realizes the core hinge, replacing the original manual operation method, which greatly reduces the labor intensity, improves the production efficiency, ensures the consistency of products, and improves product quality.

[0025] In this embodiment, the yoke assembly station includes a yoke feeding mechanism 60, a yoke traversing mechanism 70, and a yoke assembly mechanism 80. The yoke feeding mechanism 60 uses a vibratory feeder for feeding, and two vertical vibrators of unequal height are provided at the discharge end of the vibratory feeder. A yoke shaping mechanism 90 for shaping the yoke is provided between the two vertical vibrators. A rotation mechanism 100 for adjusting the assembly angle of the yoke after shaping is provided at the end of the higher vertical vibrator. Please refer to [link to relevant documentation]. Figure 3The yoke shaping mechanism 90 includes a shaping table 91, a lower shaping mold 92 disposed on the shaping table 91, and an upper moving mold 94 that closes with the lower shaping mold 92. A yoke lifting and lowering conveying assembly 93 is provided on the shaping table 91 on one side of the lower shaping mold 92. The yoke lifting and lowering conveying assembly 93 lifts the conveyed yoke to the same height as the lower shaping mold 92. The shaping table 91 also has a yoke pushing assembly 95 that pushes the lifted yoke into the lower shaping mold 92. During operation, a low-profile vibrator conveys the yoke to the yoke lifting and lowering conveying assembly 93. When sensors on both sides of the yoke lifting and lowering conveying assembly 93 detect the yoke, the yoke is lifted and lowered... The feeding component 93 is activated to lift the yoke, making it level with the lower mold 92 of the forming mold. Then, the yoke pushing component 95 pushes the yoke on the yoke conveying component 93 into the lower mold 92 of the forming mold. At this time, the upper moving mold 94 of the forming mold is activated, moves down to the lower mold 92 of the forming mold, and closes with the lower mold 92 of the forming mold. The yoke is flattened by extrusion. After the forming is completed, the upper moving mold 94 of the forming mold and the upper and lower mold conveying component 93 of the yoke are reset. The yoke pushing component 95 then pushes the yoke in the lower mold 92 of the forming mold to the highest vertical vibrator. The vertical vibrator conveys the yoke to the rotating mechanism 100, and the upper and lower mold conveying component 93 continues to convey the next yoke.

[0026] In this embodiment, please refer to Figure 4 The rotating mechanism 100 includes a rotating cylinder 101, a positioning and picking assembly 102 mounted on the rotating cylinder 101, and a mounting plate 103 located below the positioning and picking assembly 102. The mounting plate 103 has a flow port for the yoke iron to flow through. A blocking assembly 104 is provided on the mounting plate 103, located above the flow port, to limit the flow of the yoke iron from the flow port. The blocking assembly 104 is located at the discharge end of the high-speed vibrator. The blocking assembly 104 is used to block the flow of the yoke iron. When the yoke iron needs to be conveyed, the rotating cylinder 101 rotates the positioning and picking assembly 102 to the blocking assembly 104. When the side sensor detects the positioning and picking assembly 102... When the positioning and material handling assembly 102 opens the positioning component, the blocking component 104 opens simultaneously, allowing the vibrator to transport the yoke iron to the fixture of the positioning and material handling assembly 102. When the side sensor detects that the fixture of the positioning and material handling assembly 102 is full of yoke iron, the positioning and material handling assembly 102 closes the positioning component to prevent the yoke iron from falling off the fixture during rotation. At the same time, the blocking component 104 closes to prevent the yoke iron from continuing to flow. After the positioning and material handling assembly 102 closes the positioning component, the rotary cylinder 101 drives the yoke iron to rotate at a certain angle. After the rotation is completed, the positioning and material handling assembly 102 opens the positioning component again, allowing the yoke iron transverse movement mechanism 70 to grab the yoke iron on the fixture and transfer it to the iron core assembly mechanism 120.

[0027] In this embodiment, the yoke, after angle adjustment, is transferred to the yoke assembly machine by the yoke lateral movement mechanism 70, where the yoke assembly machine assembles the yoke onto the frame on the assembly table 50. Please refer to [link to relevant documentation]. Figure 5 The yoke assembly mechanism 80 is equipped with a yoke rotation angle assembly, which includes a forward moving slide 81 and a forward pushing cylinder 82 that drives the forward moving slide 81 to approach the assembly table 50. A guide rail is laterally arranged on the forward moving slide 81, and a connecting plate 84 with a rack 83 slides on the guide rail. A transverse pushing cylinder 85 that drives the connecting plate 84 to reciprocate along the guide rail is located on one side of the forward moving slide 81. A fixed plate 86 is laterally arranged on the forward moving slide 81 located on the other side of the connecting plate 84. Several rotating shafts 87 are arranged side-by-side on the fixed plate 86. 7 has a gear 88 that meshes with the rack 83 at one end and a pneumatic gripper 89 for gripping the yoke at the other end. During operation, the yoke lateral movement mechanism 70 moves the yoke to the pneumatic gripper 89, which then grips the yoke. The horizontal push cylinder 85 drives the rack 83 to move, causing the gear 88 that meshes with the rack 83 to drive the rotating shaft 87 to rotate, which in turn drives the pneumatic gripper 89 to rotate, so that the angle of the yoke matches the mounting position of the yoke on the frame on the assembly table 50. The forward push cylinder 82 pushes the forward moving slide 81 to assemble the yoke onto the frame. After assembly, the forward push cylinder 82 drives the forward moving slide 81 to reset.

[0028] In this embodiment, the core assembly station includes a core feeding mechanism 110, a core assembly mechanism 120, and a core riveting mechanism 130. The core feeding mechanism and the core assembly mechanism 120 are located between the yoke assembly mechanism 80 and the rotation mechanism 100. The core feeding mechanism 110 adopts a vibratory feeding method using a vibratory feeder. The product lateral movement mechanism 20 moves the skeleton to the assembly table 50 located at the corresponding position of the core assembly mechanism 120. The core feeding mechanism 110 transports the core to the core assembly mechanism 120, and the core assembly mechanism 120 assembles the core onto the skeleton. The skeleton with the assembled core is moved by the product lateral movement mechanism 20 to the assembly table 50 located at the corresponding position of the yoke assembly mechanism 80.

[0029] In this embodiment, please refer to Figure 6The iron core assembly mechanism 120 includes an iron core lifting assembly 121 located at the discharge end of the iron core feeding mechanism 110 and a core pusher assembly 122 that pushes the lifted iron core into the frame on the assembly table 50. The iron core lifting assembly 121 is provided with a guide block 123, which has a guide hole for the iron core to pass through. After the iron core conveyed by the iron core feeding mechanism 110 is inserted into the guide hole, the iron core lifting assembly 121 lifts the iron core to the position corresponding to the iron core installation position on the frame on the assembly table 50. Then, the core pusher assembly 122 pushes the iron core in the guide hole onto the frame to realize the installation of the iron core. After the iron core is assembled, the product transverse mechanism 20 moves the frame to the yoke assembly mechanism 80 to assemble the yoke.

[0030] To ensure effective fixation of the iron core to the frame, an iron core riveting mechanism 130 is provided. The iron core is riveted to the frame using the iron core riveting mechanism 130. (See also...) Figure 7 The core riveting mechanism 130 includes a support 131 at the bottom of the assembly table 50, a hinge head assembly 132 on the support 131 and symmetrically arranged on both sides of the assembly table 50 and movable toward the assembly table 50, a lifting assembly 133 below the hinge head assembly 132, and top pressing plates 134 on both sides of the lifting assembly 133 that respectively push the hinge head assembly 132 to move relative to each other. A top block 135 is provided on the top pressing plate 134 on one side of the hinge head assembly 132, which gradually tilts from top to bottom along the thickness direction of the top pressing plate 134. The working principle of the core riveting mechanism 130 is that when the lifting assembly 133 rises, it drives the top pressing plate 134 to rise, so that the top block 135 gradually approaches the hinge head assembly 132 and pushes the hinge head assembly 132 toward the assembly table 50, so as to realize the riveting of the core on the frame by the hinge head assemblies 132 on both sides.

[0031] The working principle of the above-mentioned high-efficiency automatic hinge machine is as follows:

[0032] The skeleton is placed on the feeding track 30, which transports it to the product traversing mechanism 20. The product traversing mechanism 20 moves multiple skeletons from the feeding track 30 to the fixture on the assembly table 50. At this time, the iron core is transported by the iron core feeding mechanism 110. After the iron core is inserted into the guide hole, the iron core lifting assembly 121 lifts the iron core to the position corresponding to the iron core installation position of the skeleton on the assembly table 50. Then, the core pushing assembly 122 pushes the iron core in the guide hole onto the skeleton to realize the installation of the iron core. After the iron core is assembled, the product traversing mechanism 20 moves the skeleton to the yoke assembly mechanism 80 to assemble the yoke.

[0033] The yoke feeding mechanism 60 conveys the yoke to the lower vibrator, which then conveys it to the yoke upper and lower conveying assembly 93. When the sensors on both sides of the yoke upper and lower conveying assembly 93 detect the yoke, the assembly starts to lift the yoke, making it level with the lower die 92 of the forming mold. Then, the yoke pushing assembly 95 pushes the yoke on the upper and lower conveying assembly 93 into the lower die 92 of the forming mold. At this time, the upper moving die 94 of the forming mold starts, moves down to the lower die 92, and closes with the lower die 92. The yoke is flattened by extrusion. After the forming is completed, the upper moving die 94 and the yoke upper and lower conveying assembly 93 are reset. The yoke pushing assembly 95 then pushes the yoke in the lower die 92 of the forming mold to the higher vibrator, which then conveys the yoke to the rotating mechanism 100.

[0034] When the yoke flows to the rotating mechanism 100, the rotating cylinder 101 rotates the positioning and picking assembly 102 to the blocking assembly 104. When the side sensor detects the positioning and picking assembly 102, the positioning and picking assembly 102 opens the positioning part, and at the same time the blocking assembly 104 opens, so that the vibrator conveys the yoke to the fixture of the positioning and picking assembly 102. When the side sensor detects that the fixture of the positioning and picking assembly 102 is full of yoke, the positioning and picking assembly 102 closes the positioning part to prevent the yoke from falling off the fixture during rotation. At the same time, the blocking assembly 104 closes to prevent the yoke from continuing to flow. After the positioning and picking assembly 102 closes the positioning part, the rotating cylinder 101 drives the yoke to rotate a certain angle. After the rotation is completed, the positioning and picking assembly 102 opens the positioning part again, so that the yoke transverse moving mechanism 70 grabs the yoke on the fixture and moves it to the iron core assembly mechanism 120.

[0035] When the yoke assembly mechanism 80 is working, the yoke lateral movement mechanism 70 moves the yoke to the pneumatic gripper 89, which grips the yoke. The lateral push cylinder 85 drives the rack 83 to move, so that the gear 88 meshing with the rack 83 drives the rotating shaft 87 to rotate, which in turn drives the pneumatic gripper 89 to rotate, so that the angle of the yoke matches the mounting position of the yoke on the frame on the assembly table 50. The forward push cylinder 82 pushes the forward moving slide 81 to assemble the yoke on the frame. After the assembly is completed, the forward push cylinder 82 drives the forward moving slide 81 to reset.

[0036] After the yoke assembly is completed, the frame of the assembled yoke is moved by the product transverse mechanism 20 to the assembly table 50 located at the corresponding position of the core riveting mechanism 130. When the core riveting mechanism 130 is working, the lifting component 133 rises, which drives the top pressing plate 134 to rise, so that the top block 135 gradually approaches the hinge head component 132 and pushes the hinge head component 132 to move toward the assembly table 50, so as to realize the riveting of the core on the frame by the hinge head components 132 on both sides.

[0037] After riveting is completed, the product lateral transfer mechanism 20 transfers the finished product to the vision inspection mechanism 150. The two vision inspection mechanisms 150 are set on both sides of the assembly table 50 through a lateral movement module. The back-and-forth movement of the vision inspection mechanism 150 can effectively detect whether there are any problems with the several products being assembled at the same time. After the inspection is completed, the product lateral transfer mechanism 20 transfers the finished product from the assembly table 50 to the discharge belt 40 for conveying. In addition, a demagnetizing mechanism 140 for eliminating the magnetism on the finished product is set on the discharge belt 40. The demagnetizing mechanism 140 adopts a demagnetizer. The demagnetizer can eliminate the magnetism on the finished product. The above-mentioned automation realizes the core hinge, replacing the original manual operation method, which greatly reduces the labor intensity, improves the production efficiency, ensures the consistency of products, and improves product quality.

[0038] In summary, this utility model, by setting up yoke assembly stations and core assembly stations on both sides of the product transverse mechanism 20, allows for the simultaneous production of multiple products on a single machine, automating assembly for high efficiency and reduced production costs. Simultaneously, the yoke shaping mechanism 90 ensures product quality during assembly and enhances product safety. This utility model automates core hinge assembly by setting up yoke assembly stations and core assembly stations on both sides of the product transverse mechanism 20 along its conveying direction, replacing the original manual operation method. This significantly reduces labor intensity, improves production efficiency, ensures product consistency, enhances product quality, and brings economic benefits to the enterprise.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
