Description

Technical Field

[0001] The utility model relates to the technical field of relay assembly, in particular to a relay assembly mechanism. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity reaches the specified requirement, it is an electrical appliance that makes the controlled quantity have a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system and the controlled system and is usually applied to an automated control circuit. During the production and assembly process of a relay, after the relay is assembled on the assembly platform, it needs to be removed from the assembly table and inserted into the corresponding test socket, and then the test socket is used to test whether it is qualified. If it is unqualified, it needs to be re-clamped and fixed on the assembly table for disassembly and then reassembled. Such a process of assembling and testing the relay will reduce the efficiency of assembling the relay and affect the production and assembly speed of the relay.

[0003] Therefore, the prior art provides a relay assembly platform with the publication number of CN220241399U. One end of the locking pin slidably connected to the support plate is inserted into the pin hole to achieve the purpose of locking the support plate, so as to facilitate the assembly of the relay locked and limited on the support plate. After the assembly is completed, the locking of the support plate is cancelled, so as to facilitate the pushing of the support plate, and the support plate drives the pins of the assembled relay to be inserted into the test socket, and the relay is tested without removing the relay, thereby improving the efficiency of assembling the relay.

[0004] After the above relay assembly platform is assembled, one hand is still needed to pull the locking pin to make it move away from the guide post against the elastic force of the locking spring, so as to cancel the locking limit of the support plate, and the other hand presses the support plate. In this way, the relay clamped and fixed on the support plate will move towards the bottom plate synchronously. Such an entire operation process still requires manual pressing, resulting in relatively laborious effort. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a relay assembly mechanism to solve the problems raised in the above background art.

Detailed Embodiment

[0018] Please refer to Figures 1-3 , a relay assembly mechanism, including a bottom plate 1, a support plate 2 and a detection seat 5. The support plate 2 is arranged above the bottom plate 1, and the detection seat 5 is fixed in the middle of the upper end of the bottom plate 1. Guide posts 11 are fixed at the four corners of the upper end of the bottom plate 1. The ends of the guide posts 11 are movably penetrated through the support plate 2. A baffle 13 is fixed at the end of the guide post 11. The baffle 13 is located above the support plate 2 and is in contact with the support plate 2. A first return spring 12 is arranged outside the guide post 11. The upper and lower ends of the first return spring 12 are respectively connected to the support plate 2 and the bottom plate 1. A window 21 is arranged in the middle of the support plate 2. The window 21 is located directly above the detection seat 5. When the support plate 2 moves downward, it can move vertically along the guide post 11. At the same time, the support plate 2 can compress the first return spring 12, and the first return spring 12 is used to reset the support plate 2.

[0019] On the left and right sides inside the window 21, a pair of L-shaped support rods 3 are symmetrically and slidably connected. The outer ends of the L-shaped support rods 3 are connected to a first threaded rod 31 through bearings. The end of the first threaded rod 31 penetrates through the support plate 2 and is threadedly connected to the support plate 2. A spacer block 32 is fixed to the end of the first threaded rod 31, and a first knob 33 is fixed to the outer end of the spacer block 32. After placing the relay base to be assembled in the window 21, rotate the two first knobs 33. The first knobs 33 drive the first threaded rod 31 to rotate. As the first threaded rod 31 is threadedly connected to the support plate 2, the two L-shaped support rods 3 clamp the relay base to be assembled from left and right.

[0020] On the front and back sides inside the window 21, a pair of clamping blocks 4 are symmetrically arranged. One end of each clamping block 4 away from the other is connected to a second threaded rod 41. The end of the second threaded rod 41 penetrates through the support plate 2 and is threadedly connected to the support plate 2. A second knob 42 is fixed to the end of the second threaded rod 41. After the two L-shaped support rods 3 clamp the relay base to be assembled, then rotate the two second knobs 42. The second knobs 42 drive the second threaded rod 41 to rotate. As the second threaded rod 41 is threadedly connected to the support plate 2, the clamping blocks 4 clamp the relay base from front and back.

[0021] A gear box 8 is fixed to the lower end of the bottom plate 1. Inside the gear box 8, there is a gear cavity 88 in the middle. At both left and right ends of the gear box 8, there are guide grooves 87 communicating with the gear cavity 88. Inside the gear cavity 88, a gear 83 is rotatably connected in the middle. On the front and back sides of the gear 83, a pair of racks 84 are symmetrically meshed. The end of the rack 84 is fixed to a connecting rod 81. The end of the connecting rod 81 extends out of the guide groove 87 on the same side and is fixed to a support block 82. The support block 82 is closely attached between the bottom plate 1 and the support plate 2. The head end of the rack 84 is fixed to a pressing plate 85. A second return spring 86 is connected between the pressing plate 85 and the inner wall of the gear cavity 88. After clamping the relay base, the relay can be assembled on the relay base clamped and fixed on the support plate 2. When the relay assembly is completed, one hand can pull one of the connecting rods 81. The connecting rod 81 drives the support block 82 to move away from between the bottom plate 1 and the support plate 2. At the same time, the connecting rod 81 drives the rack 84 to move. The rack 84 drives the gear 83 to rotate. At the same time, the rack 84 drives the pressing plate 85 to compress the second return spring 86. The setting of the second return spring 86 is for the reset of the rack 84. The gear 83 drives the other rack 84 to move in the opposite direction. In this way, the rack 84 drives the other connecting rod 81 to move. This connecting rod 81 drives the other support block 82 to move away from between the bottom plate 1 and the support plate 2. In this way, the bottom plate 1 and the support plate 2 are no longer supported by the support block 82 and abutted against the baffle 13. The setting of the spacer block 32 can ensure that the support block 82 will not be blocked by the first knob 33 and unable to move out from between the bottom plate 1 and the support plate 2.

[0022] Iron sheet seats 7 are fixed on the left and right sides of the front and rear ends of the support plate 2. An iron sheet 71 is embedded and fixed at the lower end of the iron sheet seat 7. Electromagnet seats 6 are fixed on the left and right sides of the front and rear ends of the bottom plate 1. An electromagnet 61 is embedded and fixed at the upper end of the electromagnet seat 6. A boat-shaped switch 9 is installed at the front end of the gear box 8. The boat-shaped switch 9 is electrically connected to the electromagnet 61. Through the boat-shaped switch 9, the electromagnet 61 can be powered on and off. After the connecting rod 81 drives the support block 82 to move out from between the bottom plate 1 and the support plate 2, at this time, the iron sheet 71 is attracted by the electromagnet 61, which can drive the support plate 2 to move down quickly. In this way, the support plate 2 drives the relay to move down until the pins of the relay exposed outside the relay base are inserted into the detection jacks of the detection seat 5. In this way, the relay can be tested through the detection seat 5 fixedly connected to the bottom plate 1, so that there is no need to manually press the support plate 2, which is relatively labor-saving.

[0023] Since the upper and lower sides of the inner end face of the support block 82 are both arc surfaces, after the electromagnet 61 is powered off, the support plate 2 is reset by the first return spring 12. After the support plate 2 returns to its original position, the arc surface design of the inner end face of the support block 82 can facilitate the automatic movement of the support block 82 into the space between the support plate 2 and the bottom plate 1 due to the second return spring 86.

[0024] Working principle: During the use of this assembly platform, after placing the relay base to be assembled within the window 21, rotate the two first knobs 33. The first knobs 33 drive the rotation of the first threaded rods 31. As the first threaded rods 31 are threadedly connected to the support plate 2, the two L-shaped support rods 3 clamp the relay base to be assembled from both sides. Then, rotate the two second knobs 42. The second knobs 42 drive the rotation of the second threaded rods 41. As the second threaded rods 41 are threadedly connected to the support plate 2, the clamping blocks 4 clamp the relay base from the front and back. In this way, the limiting clamping of the relay base is completed. Then, the relay can be assembled on the relay base clamped and fixed on the support plate 2. After the relay is assembled, one hand can pull one of the connecting rods 81. The connecting rod 81 drives the support block 82 to move away from between the bottom plate 1 and the support plate 2. At the same time, the connecting rod 81 drives the rack 84 to move. The rack 84 drives the gear 83 to rotate. The gear 83 drives the other rack 84 to move in the opposite direction. In this way, the rack 84 drives the other connecting rod 81 to move. This connecting rod 81 drives the other support block 82 to move away from between the bottom plate 1 and the support plate 2. In this way, the bottom plate 1 and the support plate 2 are no longer supported by the support blocks 82 and pressed against the baffle 13. At this time, by attracting the iron sheet 71 with the electromagnet 61, the support plate 2 can be driven to quickly move downward. In this way, the support plate 2 drives the relay to move downward until the pins of the relay exposed outside the relay base are inserted into the detection jacks of the detection seat 5. In this way, the relay can be tested through the detection seat 5 fixedly connected to the bottom plate 1. This is more labor-saving without manual pressing of the support plate 2. After the test is completed, cut off the power supply of the electromagnet 61. The support plate 2 is reset by the first return spring 12. After the support plate 2 returns to its original position, the arc surface design on the inner end surface of the support block 82 can facilitate the automatic movement of the support block 82 into the space between the support plate 2 and the bottom plate 1 due to the second return spring 86. Then, the relay is removed, collected, and packaged. If the relay is unqualified, it can be directly disassembled and reassembled on the support plate 2. In this way, the step of removing the relay and then inserting it into the test seat for testing in the existing assembly process is avoided, and the production and assembly efficiency of the relay is improved.
