Description

Technical Field

[0001] The present invention relates to the technical field of relay processing, and in particular to an intelligent manufacturing device for relay processing. Background Art

[0002] In order to ensure that the relay can work, it is necessary to install wiring terminals inside the relay during the production process to ensure that the current inside the relay can flow stably; because in the relay structure, the inside of the shell is divided into different accommodating spaces by setting partitions; see Figure 14-Figure 19 As shown, the correct installation method of the terminal block is as follows: the clamping portion of the terminal block is clamped on the first baffle plate, and the clamping portion is clamped with the second baffle plate under the torsion of the bending portion to stabilize the installation state of the terminal block.

[0003] In the prior art, for the installation of the terminal, the terminal is usually manually clamped by a clamp body and the clamping part is pressed into the second baffle. However, since the terminal cannot be directly assembled with the second baffle and the first baffle at the same time when it is in a free state, it needs to be bent by the pliers before it can be pressed into the correct installation position. This not only makes the installation more difficult and inefficient, but also easily causes finger injuries to personnel because the shell and the terminal are relatively sharp. More importantly, when the clamp body is clamped on both sides of the clamping part, it is easy to cause local deformation of the clamping part, resulting in the terminal being unable to be correctly installed, and then causing the clamping part to be unable to introduce all the arcs into the arc extinguishing grid (the arc extinguishing grid is located at the bottom of the clamping part) in subsequent work. Fig.14 In the right shell of the second baffle in the relay), that is, when the relay is in short-circuit protection or overload protection, some high-temperature arcs will burn through the shell.

[0059] See also Figure 1-Figure 19 ,The present invention provides a technical solution: an intelligent manufacturing device for relay processing, including a frame, a housing 304, and a terminal 30;

[0060] A first baffle 3041 and a second baffle 3042 are fixedly disposed inside the housing 304;

[0061] The connection terminal 30 includes a clamping portion 301 and a clamping portion 302, and the clamping portion 301 and the clamping portion 302 are connected via a connecting piece and an elastic bending portion 303;

[0062] It also includes a clamping unit, and the clamping unit and the housing 304 can be driven to move by the frame;

[0063] The clamping unit includes a limiting shell 9 and a first clamping rod 10, a second clamping rod 11 and a third clamping rod 12 for clamping the connecting terminal 30. The first clamping rod 10 is fixedly arranged at the lower side of the limiting shell 9. The second clamping rod 11 is located at the lower side of the limiting shell 9 and can move toward the direction close to the first clamping rod 10 and cooperate with the first clamping rod 10 to clamp the clamping portion 301. The third clamping rod 12 is located at the lower side of the limiting shell 9, and the third clamping rod 12 can open the clamping portion 302 in the direction away from the first clamping rod 10.

[0064] After the first clamping rod 10, the second clamping rod 11 and the third clamping rod 12 clamp the wiring terminal 30, the limiting shell 9 can move on the frame and place the clamped wiring terminal 30 into the correct installation position of the housing 304;

[0065] The clamping unit also includes a driving plate 14 that moves horizontally compared to the limit shell 9 and a slide groove opened on the driving plate 14; the upper end of the third clamping rod 12 is connected to the slide groove through an elastically retractable slide rod 13; the slide groove includes a driving groove 17 that can drive the third clamping rod 12 upward, a travel groove 18 and a return groove 19 that penetrates the driving plate 14; the height of the bottom surface of the return groove 19 is greater than the height of the bottom surface of the driving groove 17, and the bottom surface of the return groove 19 and the bottom surface of the driving groove 17 form a drop surface 21, and the upper end of the return groove 19 and the travel groove 18 are connected at a connection to form an inclined surface 20 for guiding the slide rod 13 to fall back.

[0066] See also Figure 1 , Figure 2 , Figure 4 and Fig.16 : In the initial state, the movement of the limit housing 9 causes the first clamping rod 10, the second clamping rod 11 and the third clamping rod 12 to be located Fig.16 The first clamping rod 10, the second clamping rod 11 and the third clamping rod 12 are all at a clampable level with the terminal block 30; then, the second clamping rod 11 moves toward the first clamping rod 10, and at the same time, the third clamping rod 12 moves away from the second clamping rod 11 under the drive of the driving plate 14, and the first clamping rod 10 cooperates with the second clamping rod 11 to clamp the clamping portion 301 of the terminal block 30, and at the same time, the third clamping rod 12 opens the clamping portion 302 of the terminal block 30, thus completing the clamping of the terminal block 30; the terminal block 30 in the clamped state below the limit shell 9 is transferred to the specified position inside the shell 304 through the frame, that is, Fig.17 Status;

[0067] Loosening process: When the connection terminal 30 is located at the correct installation position of the housing 304, the second clamping rod 11 and the driving plate 14 move toward each other, that is, the distance between the second clamping rod 11 and the first clamping rod 10 increases, thereby canceling the clamping of the clamping portion 301 of the connection terminal 30; it should be noted that, see Figure 8 and Fig.17 When the second clamping rod 11 and the driving plate 14 move toward each other, the third clamping rod 12 tends to move to the left ( Fig.17 ), then the third clamping rod 12 is blocked by the second baffle plate 3042, so when the driving plate 14 moves to the left, the third clamping rod 12 can only move upward along the driving slot 17 to compensate for the displacement difference between the third clamping rod 12 and the driving plate 14; until the third clamping rod 12 is completely out of the blocking height of the second baffle plate 3042, that is, the end of the third clamping rod 12 is located in the travel slot 18, at this time, the third clamping rod 12 releases the open state of the clamping portion 302, so that the clamping portion 302 is in contact with the second baffle plate 3042 under the elastic force of the bending portion 303, that is, Fig.18 Status in

[0068] It should be noted that when the slide bar 13 moves to the upper end of the driving groove 17, the lower end of the third clamping rod 12 is completely withdrawn from between the housing 304 and the clamping portion 302 of the terminal block 30, and then the slide bar 13 moves to the travel groove 18, and then with the movement of the driving plate 14, the slide bar 13 moves to the travel groove 18 and slides until the slide bar 13 moves to the left end of the travel groove 18 (see Fig.10 ), when the limit housing 9 is lifted by the frame again, the slide bar 13 returns to its initial position (i.e. Figure 7 );

[0069] By using the first clamping rod 10, the second clamping rod 11 and the third clamping rod 12 in coordination, the terminal block 30 can be automatically installed into the correct position of the housing 304 in a simple and quick manner, thus saving manpower. Moreover, by the displacement of the third clamping rod 12, the angle of the clamping portion 302 is fixed and the force is unidirectional, thus avoiding local deformation of the clamping portion 302, ensuring the correct installation of the terminal block 30, and avoiding partial high-temperature arc burning through the housing 304 when the relay is short-circuited or overloaded.

[0070] As a further solution of the present invention, the clamping unit further includes a driving component capable of driving the second clamping rod 11 and the third clamping rod 12 to move oppositely, so as to clamp the clamping portion 301 of the wiring terminal 30 and open the clamping portion 302;

[0071] The driving assembly includes a screw rod 15 and a servo motor 35 capable of driving the screw rod 15 to rotate; the screw rod 15 is connected to the second clamp rod 11, and a slide plate 16 is also connected to the screw rod 15, and the threads inside the second clamp rod 11 and the slide plate 16 are opposite;

[0072] The driving plate 14 is fixedly arranged at one end of the slide plate 16 away from the screw rod 15;

[0073] During operation: when the rack transports the terminal block 30 and the housing 304 to the bottom of the clamping unit, the rack moves the clamping unit to the top of the terminal block 30, and moves the clamping unit downward by a certain distance, so that the clamping rod on the clamping unit can clamp the terminal block 30;

[0074] (like Figure 4-5 As shown in the figure), the output end of the servo motor 35 is started to rotate, and the servo motor 35 drives the screw rod 15 to rotate. After the screw rod 15 rotates, it drives the second clamping rod 11 with two opposite internal threads to move in the opposite direction to the slide plate 16;

[0075] That is, the second clamping rod 11 slides in the limiting housing 9 toward the first clamping rod 10, thereby reducing the distance between the first clamping rod 10 and the second clamping rod 11, thereby clamping on the connecting terminal 30, so that the clamping portion 301 of the connecting terminal 30 can be clamped;

[0076] At the same time, the screw rod 15 drives the slide plate 16 to move to the side away from the second clamping rod 11, and the slide plate 16 drives the driving plate 14 to move to the left. The driving plate 14 synchronously drives the third clamping rod 12 to move to the left through the slide rod 13, and the clamping portion 302 of the terminal block 30 is opened at a certain angle (then the servo motor 35 stops rotating), so that the opening and closing angle of the clamping portion 302 of the terminal block 30 is greater than the position of the second baffle 3042, so as to ensure that the terminal block 30 can be stably installed in the shell 304 without being blocked; avoiding the second baffle 3042 integrally formed inside the shell 304 blocking the installation of the terminal block 30.

[0077] As a further solution of the present invention, the clamping unit further includes a fixing plate 34 fixedly connected to the limiting shell 9, the lower end of the fixing plate 34 is horizontally elastically slidably connected to the limiting plate 31, the third clamping rod 12 passes through the limiting plate 31, and the limiting plate 31 is used to vertically limit the clamping portion 302 of the terminal 30;

[0078] like Figure 4 and Figure 8 As shown, during the process of the third clamping rod 12 being pulled out from between the housing 304 and the clamping portion 302 of the terminal 30, the limiting plate 31 limits the clamping portion 302 of the terminal 30 to prevent the third clamping rod 12 from causing a small displacement of the terminal 30 due to synchronous displacement between the third clamping rod 12 and the clamping portion 302 of the terminal 30 due to friction.

[0079] As a further solution of the present invention, the clamping unit further includes a correction component;

[0080] The correction assembly includes a correction plate 27 elastically slidably connected to the limit shell 9, a correction slot 28 is provided on the correction plate 27, a driving rod 26 is slidably connected to the correction slot 28, and the driving rod 26 is horizontally slidably connected to the limit shell 9 through a sliding pair;

[0081] The upper end of the driving rod 26 is fixedly connected with a driving block 25;

[0082] The driving block 25 is slidably connected in the travel groove 18, and the end of the driving block 25 does not exceed the bottom surface of the driving groove 17;

[0083] The travel groove 18 is slidably connected with a stopper 23 which is initially inside the driving plate 14. The stopper 23 is provided with a connecting plate 24 which is movably connected to the stopper 23 at one end. The other end of the connecting plate 24 is movably connected with a pressing block 22 which is initially on the surface of the travel groove 18. The connecting plate 24 is rotatably connected to the inside of the driving plate 14.

[0084] The lower ends of the stopper 23 and the pressure block 22 are both fixedly connected with a return spring for returning them;

[0085] After the lower end of the third clamping rod 12 is completely pulled out from between the housing 304 and the clamping portion 302 of the terminal block 30; that is, the slide bar 13 is located at the junction of the driving groove 17 and the travel groove 18; Figure 6 , 7 As shown in FIGS. 9 and 11 , the slide bar 13 retracts the pressing block 22 downward into the driving plate 14 through the inclined surface of the pressing block 22. At this time, according to the seesaw principle, when the pressing block 22 descends, the stopper 23 is lifted through the connecting plate 24 to limit the driving block 25 (it should be noted that before the slide bar 13 presses the pressing block 22 into the driving plate 14, the slide bar 13 and the driving block 25 will not move in the horizontal direction; after the slide bar 13 presses the pressing block 22 into the driving plate 14, the slide bar 13 will change from the vertical motion state to the static state, and the driving block 25 will move along the driving plate 14 under the action of the stopper 23. Figure 7 During the travel of the driving plate 14, the driving block 25 is limited by the stopper 23, and the driving block 25 moves with the driving plate 14 toward the direction close to the second clamping rod 11, such as Figure 5 As shown, the driving block 25 drives the driving rod 26 to move to the left, and the driving rod 26 drives the correction plate 27 to move toward the driving plate 14 through the correction slot 28, so that the lower end of the correction plate 27 pushes the terminal 30 into the housing 304, and further corrects the position of the terminal 30 installed in the housing 304 to eliminate the problem of Figure 18-Figure 19 The displayed installation error L;

[0086] like Fig.10 As shown, the slide bar 13 then moves relatively to the left end of the travel groove 18, the slide bar 13 is out of contact with the pressure block 22, the pressure block 22 is restored to its initial position under the action of the return spring, and the block 23 is also retracted into the drive plate 14 under the action of the return spring. At the same time, the drive rod 26 that has lost its obstruction can also be reset under the reset action of the correction plate 27. It should be noted that the drive block 25 corresponding to the reset drive rod 26 is Figure 8 The left end of the stopper 23 in the middle.

[0087] As a further solution of the present invention, the upper end of the first clamping rod 10 is rotatably connected to a clamping rod 29 for further clamping the wiring terminal 30;

[0088] A spring for returning the clamping rod 29 is provided between the clamping rod 29 and the inner wall of the first clamping rod 10;

[0089] A non-slip rubber pad that gradually increases in size from top to bottom is fixedly connected to the side of the clamping rod 29 opposite to the second clamping rod 11;

[0090] A driving column 33 is fixedly connected to the second clamping rod 11 and is used to drive the clamping rod 29 to rotate at a certain tilt angle.

[0091] like Fig.12 and 13 As shown, in the process of the second clamping rod 11 moving closer to the first clamping rod 10 to clamp the terminal 30, when the second clamping rod 11 moves to two-thirds of the stroke, the driving column 33 fixedly connected to the second clamping rod 11 contacts the upper end of the clamping rod 29, and the second clamping rod 11 that continues to move causes the clamping rod 29 to rotate clockwise through the driving column 33 ( Fig.13 As shown in the figure, the clamping rod 29 is tilted inwardly at a certain angle, thereby achieving a stable clamping effect on the connecting terminal 30.

[0092] As a further solution of the present invention, a limiting rod 32 for limiting the clamping portion 302 of the connecting terminal 30 is fixedly connected to the end of the limiting plate 31 .

[0093] During operation, when the clamping unit descends to clamp the terminal block 30 , the clamping portion 302 of the terminal block 30 can be clamped between the third clamping rod 12 and the limiting rod 32 by using the limiting rod 32 , so as to achieve stable clamping of the terminal block 30 .

[0094] As a further solution of the present invention, the frame includes a workbench 1 on which two transmission belts are mounted for respectively transporting the housing 304 and the terminal block 30 to a designated position;

[0095] The workbench 1 is fixedly connected with two brackets 2 which are respectively arranged on both sides of the workbench 1 and are symmetrically arranged with respect to the workbench 1. A threaded rod 4 for making the clamping unit reciprocate linearly is fixedly connected between the two brackets 2. A driving motor 5 is fixedly connected to the end of the threaded rod 4. The driving motor 5 is fixedly connected to the bracket 2.

[0096] A tool rack 3 is fixedly connected between the two brackets 2 and below the threaded rod 4, and a slide groove is provided on the tool rack 3 to maintain stable transmission of the clamping unit;

[0097] A connecting block 6 is threadedly connected to the threaded rod 4, and the lower end of the connecting block 6 passes through the slide groove opened on the tool rack 3 and extends to the bottom of the tool rack 3. The lower end of the connecting block 6 is fixedly connected to a mounting plate 7, and the mounting plate 7 is fixedly connected to a cylinder 8 for driving the clamping unit to move in the up and down directions.

[0098] When working, (such as Figure 1 As shown in the figure, the driving motor 5 is started to drive the threaded rod 4 to rotate, and then the tool holder 3 and the threaded rod 4 are used in conjunction with each other to drive the connecting block 6 to reciprocate back and forth in the horizontal direction, and to drive the clamping unit to move in the horizontal position, and then the driving motor 5 is started to make the clamping unit move in the vertical direction.

[0099] As a further solution of the present invention, a limiting hole is provided on the clamping rod 29 to assist in stabilizing the driving column 33 on the clamping rod 29 and prevent the driving column 33 from slipping when in contact with the clamping rod 29 .
