[0002] An industrial relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. It is commonly used in automated control circuits and is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] One component of an industrial relay is the contact piece, which, after being snapped into place by a spring, is mounted on a bracket to form a switching structure. Due to the small size of the contact piece, it is currently installed primarily manually. That is, during installation, the contact piece must be manually inserted into a small hole in the bracket. The resulting structure is as follows: Figure 6 As shown. Therefore, how to utilize mechanical installation of contact pieces has become a pressing technical problem that urgently needs to be solved in this field. Utility Model Content

Detailed Implementation

[0030] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0031] Reference Figure 1-5 An industrial relay contact mounting device includes a material clamp 1, a clamping drive mechanism 2, a mounting angle adjustment mechanism 3, a lifting mechanism 4, and a front and rear positioning mechanism 5.

[0032] Specifically, the material clamp 1 is Y-shaped and includes two symmetrically designed contact jaws 11. One end of each contact jaw 11 is a mounting part 111 connected to a slider, and the other end is a clamping part 112. A connecting part 113 connects the mounting part 111 and the clamping part 112. The clamping part 112 has a clamping cavity 114 for inserting a contact piece 6 on the side where the two contact jaws 11 face each other. The outermost end of the clamping cavity 114 has a protrusion 115 that clamps the contact piece 6. The shape of the contact jaws 11 of the material clamp 1 is designed for the contact piece 6. When the two contact jaws 11 clamp one end of the contact piece 6, the protrusion 115 abuts against the surface of the contact piece 6, firmly clamping the contact piece 6 and preventing it from falling off during transport.

[0033] To control the movement of the two contact claws 11, the clamping drive mechanism 2 includes a claw connecting slider 21 connected to the contact claws 11 and a clamping drive source 22 that controls the claw connecting slider 21 to drive the two contact claws 11 to move towards or away from each other. The claw connecting slider 21 is detachably connected to the mounting part 111 of the contact claws 11 by screws. The clamping drive source 22 is a cylinder. The clamping drive source 22 has a detachable groove 221 on its end face facing the contact claws 11. The claw connecting slider 21 is slidably connected to the groove 221. The clamping drive source 22 controls the two claw connecting sliders 21 to move towards or away from each other within the groove 221, thereby driving the two contact claws 11 to move towards or away from each other, realizing the clamping and releasing of the contact 6.

[0034] To adjust the installation angle of the contact piece 6, the installation angle adjustment mechanism 3 includes a rotating connector 31 connected to the clamping drive source 22 and a rotating drive source 32 that drives the rotating connector 31 to rotate; the rotating drive source 32 is an angle adjustment servo motor. The rotating connector 31 includes a rotating shaft 311 connected to the rotating drive source 32 and a bushing 312 sleeved on the rotating shaft 311. One end of the rotating shaft 311 is connected to the rotating drive source 32, and the other end is connected to the clamping drive mechanism 2. One end of the bushing 312 is connected to the clamping drive source 22. A limiting protrusion 3111 is provided on the circumferential side of the rotating shaft 311, and a limiting recess 3121 is provided on the inner side of the bushing 312 to engage with the limiting protrusion 3111. This design allows the bushing 312 to rotate synchronously with the rotating shaft 311, thereby driving the clamping drive mechanism 2 to rotate synchronously, and thus adjusting the installation angle of the contact piece 6.

[0035] To adjust the installation height of the contact piece 6, the lifting mechanism 4 includes a lifting connector 41 connected to the rotary drive source 32 and a lifting drive source 42 that drives the lifting connector 41 to move up and down; the lifting connector 41 is an "L"-shaped plate. Specifically, the lifting drive source 42 is a lifting servo motor. The lifting connector 41 includes a first connecting plate 411 connected to the rotary drive source 32, and a second connecting plate 412 is vertically connected to one side of the first connecting plate 411. The second connecting plate 412 has a lifting slider 413 on the side near the lifting drive source 42, and the clamping drive source 22 is installed on the other side of the second connecting plate 412. The lifting drive source 42 drives the lifting slider 413 to move up and down, thereby driving the lifting connector 41 to drive the rotary drive source 32 to move up and down, and thus driving the contact piece 6 to move up and down synchronously.

[0036] To facilitate the insertion of the contact piece 6 into the bracket of the industrial relay, the front and rear positioning mechanism 5 includes a front and rear connecting member 51 connected to the lifting drive source 42 and a front and rear drive source 52 that drives the front and rear connecting member 51 to reciprocate back and forth. The front and rear connecting member 51 includes a front and rear slider 511 connected to the front and rear drive source 52 by a lead screw and a mounting bracket 512 disposed on the top of the front and rear slider 511. The lifting drive source 42 is mounted on the mounting bracket 512. This design allows the front and rear drive source 52 to drive the entire lifting mechanism 4 to reciprocate back and forth when driving the front and rear slider 511.

[0037] Because the installation accuracy of the contact piece 6 is high, in order to accurately insert the contact piece 6 into the small hole of the bracket, the front and rear drive source 52 includes a mounting base 521, a lead screw 522 disposed inside the mounting base 521, and a front and rear positioning motor 523 that drives the lead screw 522 to rotate. The front and rear sliders 511 are movably connected to the lead screw 522. The top two sides of the mounting base 521 are provided with guide rails 5211, and the bottom two sides of the front and rear sliders 511 are provided with slots 5111 that are adapted to the guide rails 5211. The front and rear positioning motor 523 drives the lead screw 522 to rotate, and the lead screw 522 drives the front and rear sliders 511 to move back and forth along the direction of the guide rails 5211, thereby driving the lifting mechanism 4 to move back and forth. Since the lead screw 522 converts rotary motion into linear motion, its stroke accuracy is high, which greatly improves the accuracy of the mechanized installation of the contact piece 6.

[0038] Working principle: The contact pieces 6 are first arranged one by one by the vibratory plate and conveyed to the front of the material clamping device 1 by the contact piece conveying mechanism. The clamping drive source 22 controls the two contact piece grippers 11 of the material clamping device 1 to move towards each other and clamp the contact pieces 6. Then the contact piece conveying mechanism moves and resets. After the installation angle adjustment mechanism 3, the lifting mechanism 4 and the front and rear positioning mechanism 5 adjust the position multiple times, the contact pieces 6 are installed in the bracket of the industrial relay. Then the reset is repeated to achieve the mechanized installation of the contact pieces 6.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
