Description

Technical Field

[0001] The present invention relates to the technical field of relays, and in particular to a relay production and processing device and a processing technology. Background Art

[0002] A relay is an electrical control device, usually used in automated control circuits. Relays play the role of automatic adjustment, safety protection, and circuit conversion in circuits.

[0003] During the production process of relays, the terminals of the relays need to be inserted into the terminal holders to facilitate the subsequent production and processing of the relays. Currently, when the terminals are assembled with the cavities, the terminals are mostly pressed into the cavities. Therefore, the terminals are easily caught on the cavity openings, etc., which leads to a high possibility of terminal insertion failure.

[0004] For the above-mentioned problem of high possibility of terminal insertion failure, the prior art provides corresponding solutions, for example: a terminal insertion device with publication number CN102449861A, which can position the wire with the terminal so that the terminal can be inserted into the cavity, so that it is difficult for the terminal to get caught on the opening of the cavity, and the failure of inserting the terminal into the cavity can be minimized.

[0005] However, the terminal insertion device provided by the above patent still has the following problems: 1. When the terminal is plugged into the cavity, the above device needs to pass through a pair of holding parts and a terminal insertion guide part and move to the front of the cavity to guide the terminal. Therefore, the device has a complex structure and is relatively cumbersome to operate in actual application.

[0006] 2. Before the terminals are plugged into the cavity, the terminals need to be inserted into the device one by one by manual operation. Therefore, if the workers fail to insert the terminals in time, the subsequent processes will not be able to proceed normally, which will easily affect the overall plug-in efficiency of the terminals and the cavity. In addition, deviations are prone to occur during the manual installation process, affecting the plug-in accuracy between the terminals and the cavity. Summary of the invention

[0037] See also Figure 2 and Figure 3A guide cylinder 31 is installed at the lower end of the discharge box 3 and at the discharge port 57. The cross-section of the upper half of the guide cylinder 31 is a trapezoidal structure with a width that gradually decreases from top to bottom, and the cross-section of the lower half of the guide cylinder 31 is a rectangular structure. A plurality of telescopic balls 311 are evenly rotated between the inclined section and the vertical section of the guide cylinder 31; the terminal 6 may tilt when it falls into the guide cylinder 31, so when the installation unit 5 presses the terminal 6 downward, the bottom of the terminal 6 abuts against the telescopic ball 311, so that the telescopic ball 311 can shrink and reduce the distance between the terminal 6 and the inner wall of the guide cylinder 31. The friction force ensures that the installation unit 5 can smoothly squeeze the terminal 6 into the vertical section of the guide cylinder 31; the right side wall of the guide cylinder 31 is installed with a second cylinder 32 through a fixed seat, and the telescopic end of the second cylinder 32 is installed with a stopper 33; the terminal 6 can be guided by the guide cylinder 31. In addition, by opening the second cylinder 32, the second cylinder 32 can drive the stopper 33 to move downward and limit the terminal seat 43, so as to calibrate the placement position of the terminal seat 43, so that the terminal seat 43 is aligned with the guide cylinder 31, so as to ensure the accuracy of the terminal 6 falling on the terminal seat 43, thereby improving the installation efficiency of the terminal 6.

[0038] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The installation unit 5 includes a feeding port 51, a transmission roller 52, a first intermittent motor 53, a limiting shaft 54, a support group 55, a rotating roller 56, a discharge port 57 and a feeding assembly 58, wherein: a feeding port 51 is provided on the upper side of the discharge box 3 and close to its right side, a plurality of transmission rollers 52 are rotatably arranged between the front and rear side walls on the right side of the discharge box 3, and the plurality of transmission rollers 52 are connected by belt transmission, a first intermittent motor 53 is provided at the front end of the discharge box 3 through a motor cover, and an output shaft of the first intermittent motor 53 is connected to the transmission roller 52 on the far right of the discharge box 3, and support groups 55 are installed on the front and rear side walls on the left side of the discharge box 3, and the support group 55 includes two V-shaped frames 551 arranged symmetrically on the left and right, and the opposite sides of the left and right V-shaped frames 551 are arranged between the inner wall of the discharge box 3 A limit axis 54 is rotatably arranged, and a rotating roller 56 is rotatably arranged between the front and rear two opposite V-frames 551 at equal intervals. A discharge port 57 is provided at the bottom of the discharge box 3 and below the support group 55, and a material discharge assembly 58 is installed on the inner wall of the discharge box 3; stop plates 552 are arranged at the corners of the two V-frames 551 and near the tops of the opposite sides thereof, and a limit plate 553 is installed between the stop plates 552 on the V-frame 551 on the left side of the discharge box 3; when the terminal 6 moves on the rotating roller 56, the terminal 6 on the top of the rotating roller 56 can be limited by the limit plate 553, so that the terminal 6 is located in the middle of the support group 55; in the initial state, the opposite sides of the left and right V-frames 551 are in a horizontal state, and the opposite sides of the left and right V-frames 551 are in an inclined state (such as Figure 2 As shown), the terminal 6 moves along the rotating roller 56 to between the two V-shaped frames 551 under the action of gravity. At this time, the rotating roller 56 located on the opposite side of the two V-shaped frames 551 is at the same height as the transmission roller 52, so that the transmission roller 52 can transport the terminal 6 to the rotating roller 56; it should be noted that the first intermittent motor 53 can only transport one terminal 6 to the rotating roller 56 each time the transmission roller 52 rotates, thereby facilitating the sequential unloading of the terminal 6, and the intermittent rotation frequency of the first intermittent motor 53 and the second intermittent motor 44 is consistent, so that the second intermittent motor 44 can only transport the terminal seat 43 to the bottom of the guide cylinder 31 in sequence, so as to facilitate the continuous assembly of the terminal 6 and the terminal seat 43.

[0039] During operation, the first intermittent motor 53 is turned on, and the first intermittent motor 53 drives the transmission roller 52 to rotate intermittently counterclockwise, and then the terminals 6 are placed on the transmission roller 52 in sequence through the feeding port 51, and the transmission roller 52 drives the terminals 6 to move intermittently to the left (such as Figure 2 As shown), the terminal 6 is then moved onto the rotating roller 56 under the action of the transmission roller 52, so that the terminal 6 is moved between the two V-shaped frames 551 under the action of the rotating roller 56, so that the blanking component 58 can install the terminal 6 on the V-shaped frame 551 between the terminal seat 43.

[0040] See also Figure 4 , Figure 5 and Figure 6 The material unloading assembly 58 includes a first cylinder 581, a lower pressure plate 582, a linkage rod 583, a resisting roller 584, a positioning plate 585, a telescopic rod 586, a sliding groove 587 and a limiting slider 588, wherein: the first cylinder 581 is installed on the top of the material unloading box 3 and above the support group 55, the telescopic end of the first cylinder 581 is provided with a lower pressure plate 582, the top of the lower pressure plate 582 is symmetrically and evenly provided with fixing rods, the left and right side walls of the lower pressure plate 582 are both symmetrically provided with two linkage rods 583, the linkage The rod 583 is an L-shaped structure. The end of the linkage rod 583 away from the lower pressure plate 582 is rotatably provided with a resistance roller 584. The resistance roller 584 is rotatably abutted against the upper end of the V-shaped frame 551. Two positioning plates 585 are symmetrically arranged along the support group 55 between the front and rear side walls of the discharge box 3. The opposite sides of the two positioning plates 585 are hinged with telescopic rods 586. The telescopic rods 586 can be retracted under the action of external force. When there is no external force, the telescopic rods 586 can be restored to the initial state. The bottom of the opposite side of the V-shaped frame 551 is provided with a sliding groove 58 7. The end of the telescopic rod 586 away from the positioning plate 585 is hinged with a limit slider 588 slidably set in the sliding groove 587; when the V-shaped frame 551 rotates downward along the limit axis 54, the telescopic rod 586 contracts under the extrusion force of the V-shaped frame 551, and the limit slider 588 at its telescopic end moves along the sliding groove 587; when working, the first cylinder 581 is turned on, the telescopic end of the first cylinder 581 extends and drives the lower pressure plate 582 to move downward, and the linkage rod 583 moves downward with the lower pressure plate 582 and passes through the friction The roller 584 drives the V-shaped frame 551 to rotate downward along the limit shaft 54. When the abutting roller 584 abuts against the stop plate 552, the linkage rod 583 cannot continue to move downward under the action of the stop plate 552. At this time, the V-shaped frame 551 stops rotating and the distance between the two V-shaped frames 551 is greater than the width of the terminal 6, so that the terminal 6 at the upper end of the V-shaped frame 551 loses the supporting force of the V-shaped frame 551 and falls downward into the discharge port 57. Subsequently, the terminal 6 is adjusted to a vertical state under the action of the guide cylinder 31 and falls on the upper end of the terminal seat 43.

[0041] See also Figure 4 , Figure 7 and Figure 8A connecting groove 591 is provided in the middle of the lower pressing plate 582, and a card groove 592 is symmetrically provided on the inner wall of the connecting groove 591. A detachable actuating plate 593 is slidably provided in the connecting groove 591, and a protective pad 597 is detachably installed on the bottom of the detachable actuating plate 593; the protective pad 597 can avoid the conflict between the detachable actuating plate 593 and the terminal 6, and prevent the detachable actuating plate 593 from causing an indentation on the terminal 6; the outer wall of the detachable actuating plate 593 is symmetrically provided with a clearance groove 594, and a plurality of supporting elastic members 595 are installed at equal intervals in the clearance groove 594, and the plurality of supporting elastic members 595 are away from the detachable One end of the disengagement actuator plate 593 is commonly installed with a top contact block 596 that slides and abuts in the slot 592; the cross-section of the slot 592 is a triangular structure, and the cross-section of the top contact block 596 is a triangular structure that matches the slot 592; the triangular structure facilitates the slot 592 to limit the top contact block 596 and facilitates the top contact block 596 to be snapped into the slot 592; the shift plate 552 can limit the lower pressure plate 582 through the linkage rod 583, so that the first cylinder 581 drives the detachable actuator plate 593 to detach from the lower pressure plate 582, so as to facilitate the detachable actuator plate 593 to press the terminal 6 into the terminal seat 43.

[0042] When the linkage rod 583 cannot move downward under the action of the shift plate 552, the telescopic end of the first cylinder 581 continues to extend, so that the first cylinder 581 drives the detachable actuator plate 593 to detach from the connecting groove 591 and move downward (such as Figure 4 As shown), during this period, the top contact block 596 shrinks into the yield groove 594 under the action of the card slot 592, and when the detachable actuator plate 593 is detached from the lower pressure plate 582, the top contact block 596 is reset under the action of the supporting elastic member 595. At this time, the first cylinder 581 drives the detachable actuator plate 593 to move downward and pass through the guide cylinder 31 to abut against the top of the terminal 6. Then the first cylinder 581 presses the terminal 6 downward into the terminal seat 43 through the detachable actuator plate 593 to complete the assembly between the terminal 6 and the terminal seat 43; after the processing is completed, the telescopic end of the first cylinder 581 shrinks and drives the detachable actuator plate 593 to reset upward. During this period, the detachable actuator plate 593 is reset. The detachable actuator plate 593 drives the top contact block 596 to abut against the bottom of the lower pressure plate 582 and drives the lower pressure plate 582 and the linkage rod 583 to reset upward. When the fixed rod at the top of the lower pressure plate 582 conflicts with the upper inner wall of the discharge box 3, the lower pressure plate 582 cannot continue to move upward. At this time, the first cylinder 581 drives the detachable actuator plate 593 to continue to move upward and makes the top contact block 596 abut against the slot 592 under the action of the lower pressure plate 582, and the detachable actuator plate 593 is reset to the connecting slot 591; at the same time, the V-frame 551 loses the pressing force of the linkage rod 583 and the contact roller 584 and returns to its initial state under the action of the telescopic rod 586.

[0043] The specific processing technology of the relay production and processing equipment during terminal insertion includes the following steps: the first step: first turn on the second intermittent motor 44, and drive the conveyor belt 42 to rotate intermittently clockwise by the second intermittent motor 44, and then place the terminal seats 43 on the conveyor belt 42 in sequence, so that the conveyor belt 42 drives the terminal seats 43 to move to the right in sequence to under the guide cylinder 31, and then turn on the second cylinder 32, and drive the stopper 33 to move downward by the second cylinder 32 and calibrate the placement position of the terminal seat 43.

[0044] Step 2: Turn on the first intermittent motor 53, and drive the transmission roller 52 to rotate intermittently counterclockwise through the first intermittent motor 53, and then place the terminals 6 on the transmission roller 52 in sequence through the feeding port 51, and drive the terminals 6 to move to the left to the rotating roller 56 through the transmission roller 52, and the terminals 6 move to the middle of the support group 55 under the action of the rotating roller 56.

[0045] Step 3: Open the first cylinder 581. The first cylinder 581 drives the linkage rod 583 to move downward through the lower pressure plate 582 and causes the V-shaped frame 551 to rotate downward along the limiting axis 54 through the resistance roller 584, so that the terminal 6 loses the supporting force of the V-shaped frame 551 and falls into the discharge port 57. Subsequently, the terminal 6 is adjusted to a vertical state under the action of the guide cylinder 31 and falls on the upper end of the terminal seat 43.

[0046] Step 4: The linkage rod 583 and the lower pressure plate 582 are limited by the shift plate 552 so that they cannot move downward. At this time, the first cylinder 581 drives the detachable actuator plate 593 to detach from the lower pressure plate 582 and move downward to rest against the top of the terminal 6. Then, the first cylinder 581 presses the terminal 6 downward into the terminal seat 43 through the detachable actuator plate 593 to complete the assembly between the terminal 6 and the terminal seat 43.

[0047] Step 5: After the relay terminal assembly process is completed, the first cylinder 581 drives the detachable actuator plate 593 to reset upward and reset the detachable actuator plate 593 to the connecting groove 591. At the same time, the V-shaped frame 551 loses the pressing force of the linkage rod 583 and the resistance roller 584 and returns to the initial state under the action of the telescopic rod 586. The above working steps are a working cycle for the assembly process of the terminal 6 and the terminal seat 43 of the present invention.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
