Description

Technical Field

[0001] This utility model relates to the technical field of industrial relay production equipment, specifically to a spring feeding device for industrial relay assembly. Background Technology

[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] Industrial relays require springs in their switching structure. During installation, one end of the spring needs to engage with the contact plate, and the other end needs to engage with the bracket. Due to the small size of the spring, it is currently installed primarily manually. This involves manually compressing the spring and inserting it into a small hole in the bracket, ensuring both ends engage with the contact plate and the bracket respectively. To achieve mechanized spring installation, the first step is to solve how to quickly and reliably deliver each spring to the industrial relay assembly equipment, enabling the spring mounting device on the assembly equipment to quickly grasp and hold the springs. Utility Model Content

Detailed Implementation

[0033] 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:

[0034] Reference Figure 1-8 A spring feeding device for industrial relay assembly includes a vibratory plate 1, a linear feeding mechanism 2, a clamping mechanism 3, and a lateral moving mechanism 4.

[0035] Specifically, the vibratory feeder 1 has two discharge pipes 11 at its outlet. The diameter of each discharge pipe 11 is adapted to the diameter of the spring 5, and each discharge pipe 11 can discharge one spring 5. The circumferential side of each discharge pipe 11 has a side opening 111 for easy observation of the material. The two ends of the side opening 111 extend to the entire discharge pipe 11, allowing the operator to easily observe the discharge status of the spring 5. If jamming occurs, it can be addressed through the side opening 111.

[0036] To guide the springs 5 ​​in the two discharge pipes 11 one by one into the industrial relay assembly equipment, the linear feeding mechanism 2 includes a mounting bracket 21 and a linear feeding platform 22 mounted on the mounting bracket 21. The linear feeding platform 22 is provided with feeding tracks 23 connected to the discharge pipes 11. The feeding tracks 23 have U-shaped grooves with openings at the top. Since the vibratory feeder 1 has two discharge pipes 11, the linear feeding platform 22 is also provided with two feeding tracks 23. The two feeding tracks 23 are located on both sides of the linear feeding platform 22 and correspond one-to-one with the two discharge pipes 11. The springs 5 ​​on the vibratory feeder 1 enter the feeding tracks 23 through the discharge pipes 11. A linear vibratory feeder 24 is provided at the bottom of the linear feeding platform 22. The design of the linear vibratory feeder 24 allows the springs 5 ​​in the two feeding tracks 23 to move in a straight line, ensuring that there are always springs 5 ​​at the discharge ends of the two feeding tracks 23 for the clamping mechanism 3 to clamp. The spring 5 feeding device in this embodiment is a dual-station discharge design, which can output two springs 5 ​​at the same time to meet the rapid production requirements of mechanized installation and achieve high production efficiency.

[0037] To quickly grip the spring 5 at the discharge end of the feeding track 23, the gripping mechanism 3 includes a spring clamp 31, a gripping drive source 32 for controlling the spring clamp 31 to grip the spring 5 on the feeding track 23, and a rotation drive source 33 for controlling the rotation of the spring clamp 31. The gripping drive source 32 is a cylinder. The rotation drive source 33 is a servo motor. The spring clamp 31 includes two symmetrically arranged grippers 311, and the gripping drive source 32 controls the two grippers 311 to move towards or away from each other. Each of the two grippers 311 has a gripping portion 312 extending outward from one end on its facing side. The free end of the gripping portion 312 is provided with a limiting arc portion 313 whose shape is adapted to the spring 5. After the two grippers 311 are closed, a locking interface 314 is provided on one side of the limiting arc portion 313 for the feeding track 23 discharge end to engage. The discharge end of the feeding track 23 is provided with a material-taking notch 231 for the gripping portion 312 of the grippers 311 to insert into. When the rotary drive source 33 controls the gripping portion 312 of the two grippers 311 to rotate to both sides of the material-taking notch 231 of the feeding track 23, the gripping drive source 32 drives the two grippers 311 to move towards each other until the gripping portion 312 of the two grippers 311 inserts into the material-taking notch 231 and abuts against each other. At this time, the limiting arc portion 313 of the two grippers 311 forms a circle that can engage the spring 5. Since the spring 5 is engaged in the limiting portion, when the rotary drive source 33 controls the two grippers 311 to rotate, the spring 5 can be taken away from the feeding track 23.

[0038] To enable the gripping drive source 32 to control the two grippers 311 to move towards or away from each other, a connecting slider 34 is provided at the other end of each gripper 311 relative to the gripping part 312. The connecting slider 34 has a mounting protrusion 341 protruding outward on the side facing the gripper 311, and the gripper 311 is mounted on the mounting protrusion 341 by screws. The gripping drive source 32 is provided with a sliding groove 321, which drives the two connecting sliders 34 to move towards or away from each other within the sliding groove 321, thereby gripping or releasing the spring 5.

[0039] To accurately deliver spring 5 to the spring mounting device 7 of the industrial relay assembly equipment, the lateral movement mechanism 4 includes a lateral connecting member 41 and a lateral drive source 42 that drives the lateral connecting member 41 to reciprocate. A rotary drive source 33 is mounted on the lateral connecting member 41. The lateral drive source 42 can be a cylinder. The lateral connecting member 41 is an "L"-shaped plate, comprising a first connecting plate 411 and a second connecting plate 412 that are vertically connected. The rotary drive source 33 is mounted on the first connecting plate 411, and the lateral drive source 42 is mounted at the bottom of the second connecting plate 412. When the lateral drive source 42 drives the lateral connecting member 41 to move laterally, the lateral connecting member 41 drives the rotary drive source 33, which in turn drives the spring 5 to move laterally. A longitudinal adjustment mechanism 6 is provided at the bottom of the lateral movement mechanism 4. The longitudinal adjustment mechanism 6 can be a cylinder. When the height of the spring 5 needs to be adjusted, it can be adjusted using the longitudinal adjustment mechanism 6.

[0040] Working principle: First, the spring 5 material is placed into the vibrating plate 1. Then, the vibrating plate 1 vibrates to shake the spring 5 out from the two discharge pipes 11, and then into the two feeding tracks 23 on the linear feeding table 22. Next, the vibration of the linear feeder 24 causes the spring 5 in the two feeding tracks 23 to move forward in a straight line. Then, the rotation drive source 33 of the clamping mechanism 3 controls the clamping parts 312 of the two jaws 311 to rotate to both sides of the material picking notch 231 of the feeding track 23. The clamping drive source 32 drives the two jaws 311 to move towards each other until the clamping parts 312 of the two jaws 311 insert into the material picking notch 231 and abut against each other to engage the spring 5 (e.g., spring 5). Figure 5 (As shown); then the rotation drive source 33 controls the clamping drive source 32 to drive the two grippers 311 to rotate synchronously by 90° (the state after rotation is as shown). Figure 4 (As shown); Next, the lateral moving mechanism 4 drives the lateral connecting member 41 to deliver the spring 5 to the spring mounting device 7 of the industrial relay assembly equipment. After the spring mounting device 7 of the industrial relay assembly equipment clamps the spring 5, the clamping drive source 32 drives the two grippers 311 to move in opposite directions to release the spring 5, so that the spring mounting device 7 can clamp the spring 5. Finally, the lateral moving mechanism 4 and the clamping mechanism 3 reset, and the above operation is repeated.

[0041] 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.
