Description

Technical Field

[0001] This utility model relates to the field of relay assembly equipment technology, and in particular to a static spring riveting mechanism. Background Technology

[0002] As an indispensable key component of electrical control systems, the stability and durability of the electrical contact system of relays are of paramount importance.

[0003] The current-guiding copper sheets (stationary springs, bridging sheets) and contacts are the main components of this system, and their connection quality directly determines the service life and performance of the relay. In the crucial step of contact riveting, traditional manual and electric punch press riveting methods have many shortcomings. Because the punch press's stroke is fixed, it cannot be flexibly adjusted according to the actual size and tolerance of the parts, resulting in inconsistent contact riveting firmness, affecting product consistency and reliability.

[0004] Furthermore, manual riveting is inefficient and cannot meet the demands of large-scale production. Although some manufacturers have introduced automated riveting equipment, several problems still exist in actual operation. For example, when the finished product is gripped and output by a robotic arm after riveting, the structural limitations of the riveting groove restrict the gripping movement, leading to unstable material handling and subsequent material slippage. This not only affects the continuity of the riveting process but also significantly reduces output efficiency. Therefore, optimizing the contact riveting process and improving riveting efficiency is crucial for enhancing the overall performance of relay products. Utility Model Content

[0005] This utility model provides a relay pusher assembly mechanism, which helps to solve the problem that some static spring riveting mechanisms use clamping robots to rivet finished products. Due to the limitations of the riveting groove structure, the material is easily unstable and thus the material is detached, which affects the riveting efficiency.

[0006] This utility model is implemented as follows:

[0007] A static spring riveting mechanism includes a feeding device for supplying moving contacts. The feeding device includes a vibratory plate, the output end of which is provided with a linear vibrating track, and the output end of the linear vibrating track is provided with a riveting seat. The riveting seat is provided with a riveting groove, and a riveting machine is provided directly above the riveting groove. A guide rail is provided on one side of the riveting seat. A pushing assembly for rotating the moving contacts one by one is provided between the riveting groove and the output end of the linear vibrating track. A pressing assembly for locally pressing the static springs within the riveting groove is provided on one side of the riveting groove. A lifting assembly for lifting the riveted static springs is provided at the bottom of the riveting groove. A blowing air pipe is provided on one side above the riveting groove. The air outlet of the blowing air pipe is positioned opposite the inlet of the guide rail on both sides of the riveting groove. The blowing air pipe is connected to an external positive pressure air supply mechanism, enabling it to blow the lifted static springs onto the guide rail, forming a disengaged blowing and discharging structure.

[0008] Based on the above technical solution, the feeding device is also provided with a vibrating hopper on one side of the vibrating plate for transition feeding to the vibrating plate.

[0009] Based on the above technical solution, the riveting base includes a support frame, the top of the support frame is provided with a detachable support seat, and the riveting groove is an open groove structure set on the top of the support seat for placing the stationary spring sheet and the moving contact to be riveted.

[0010] Based on the above technical solution, the riveting groove is provided with a contact mold rod, and the top of the contact mold rod is used for a groove structure to limit the moving contact.

[0011] Based on the above technical solution, the contact mold rod and the support base are detachably connected.

[0012] Based on the above technical solution, the support base is provided with a feeding groove near the output end of the linear vibration track, and a pushing groove is provided between the end of the feeding groove and the riveting groove. The pushing component is provided with a pushing block that can slide back and forth along the pushing groove. The pushing block can push the moving contacts at the end of the feeding groove one by one to the top of the contact mold rod in the riveting groove.

[0013] Based on the above technical solution, the top material assembly is provided with a top material block, which extends from the bottom of the support base to the riveting groove above. The bottom of the top material block is connected to a lifting cylinder, which is fixed on the support frame.

[0014] Based on the above technical solution, a positioning detection component is provided on the outside of the riveting groove.

[0015] Based on the above technical solution, the positioning detection component includes a sheet metal bracket, the top of which is provided with a bent portion, and a mounting hole is provided on the bent portion, in which a sensor is installed.

[0016] Based on the above technical solution, a material box is provided at the output end of the material guide rail.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] This invention, by setting a top-feeding component and a blowing air pipe at the riveting groove, and setting a guide rail adapted to the blowing air pipe, allows the product riveted in the riveting groove to be lifted off the bottom of the riveting groove by the top-feeding component. This helps prevent the product from being excessively jammed in the riveting groove after riveting. Subsequently, the blowing air pipe outputs air of appropriate intensity to transfer the product to the guide rail for output. The disengagement blowing and discharge structure completes the discharge action, replacing the traditional clamping mechanism. This helps to solve the problem that some static spring riveting mechanisms use clamping robots to discharge riveted finished products, which are prone to unstable gripping due to the limitations of the riveting groove structure, resulting in material detachment and affecting riveting efficiency.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Combination Figure 1-6This embodiment discloses a static spring riveting mechanism, which aims to solve the problems of unstable material gripping, material slippage, and low riveting efficiency in the static spring riveting process of the prior art.

[0032] The static spring riveting structure includes a feeding device 100, a riveting seat 200, a riveting machine 300, a guide rail 400, and a material box 500.

[0033] The feeding device 100 is used to stably supply the moving contact, which is used to assemble the stationary spring on the riveting base 200 to complete the riveting. Specifically, as shown... Figure 1 As shown, the feeding device 100 includes a vibratory feeder, which stores a certain number of moving contacts. Vibration feeding ensures the moving contacts are output in an orderly manner. The output end of the vibratory feeder is equipped with a linear vibration track 120, which allows the moving contacts to be output in a linear sequence. Additionally, the feeding device 100 has a vibratory hopper 110 on one side of the vibratory feeder for transition feeding material to the vibratory feeder, ensuring that the external transfer mechanism can supply material to the vibratory feeder in an orderly and controllable manner.

[0034] The output end of the linear vibrating track 120 is provided with a riveting seat 200. The riveting seat 200 includes a support frame 210. The top of the support frame 210 is provided with a detachable support seat 220. The support seat 220 is fixedly installed on the top of the support frame 210 by bolts. The support seat 220 is provided with a riveting groove 221. The riveting groove 221 is an open groove structure provided on the top of the support seat 220 for placing the stationary spring and moving contact to be riveted.

[0035] A riveting machine 300 is located directly above the riveting groove 221, combined with... Figure 5 As shown, the riveting machine 300 includes a riveting bracket 310, with a riveting cylinder 320 on top of the bracket 310. The riveting cylinder 320 is a booster cylinder structure, with its output end vertically downward and connected to a riveting punch 330. To make the vertical punching path of the riveting punch 330 more stable and reliable, a vertically arranged guide rail is also provided between the riveting punch 330 and the riveting bracket 310. During operation, the riveting cylinder 320 drives the riveting punch 330 downward to rivet the moving contact of the stationary spring in the riveting groove 221 located directly below, thus riveting it to the stationary spring.

[0036] Among them, combined Figure 3 and Figure 4 To ensure the precise positioning of the moving contact within the riveting groove 221, a contact mold 222 is provided within the riveting groove 221. The top of the contact mold 222 has a groove structure for limiting the position of the moving contact. In this embodiment, the contact mold 222 and the support base 220 are detachably connected by bolts. This facilitates the replacement of the contact mold 222 according to the specifications of the actual moving contact, improving the processing adaptability of the equipment.

[0037] A pusher assembly 230 for rotating the moving contacts one by one is provided between the riveting groove 221 and the output end of the linear vibration track 120. The support base 220 is provided with a feeding groove 224 near the output end of the linear vibration track 120. A pusher groove 225 is provided between the end of the feeding groove 224 and the riveting groove 221. The length directions of the feeding groove 224 and the pusher groove 225 are perpendicular. The pusher assembly 230 is provided with a pusher block 231 that can slide back and forth along the pusher groove 225. A cylinder is connected to the side of the pusher block 231 away from the riveting groove 221. The pusher block 231 is provided with a material groove with a side opening groove structure at the end facing the riveting groove 221 for accommodating the moving contacts one by one. The pusher block 231 can push the moving contacts at the end of the feeding groove 224 one by one to the top of the contact mold rod 222 in the riveting groove 221. Therefore, the effect of feeding the moving contacts one by one between the feeding device 100 and the riveting groove can be achieved.

[0038] A pressing assembly 240 is provided on one side of the riveting groove 221 for locally pressing the stationary spring sheet in the riveting groove 221. The pressing assembly 240 includes a pressing block 241. A cylinder is connected to the side of the pressing block 241 away from the riveting groove 221. The pressing block 241 has a side opening structure facing the riveting groove 221. When the pressing block 241 moves laterally into place towards the riveting groove 221, it can longitudinally press and limit the stationary spring sheet located in the riveting groove 221, so that the stationary spring sheet maintains a stable posture during the subsequent riveting process, thereby improving the riveting quality.

[0039] The bottom of the riveting groove 221 is provided with a lifting assembly 250 for lifting the stationary spring sheet after riveting. The lifting assembly 250 has a lifting block 251, which extends from the bottom of the support base 220 to the upper riveting groove 221. The bottom of the lifting block 251 is connected to a lifting cylinder, which is fixed on the support frame 210. During operation, the product riveted in the riveting groove 221 can be lifted and removed from the bottom of the riveting groove 221 by the lifting assembly 250. This helps to prevent the product from getting too stuck in the riveting groove 221 after riveting, thus improving the stability of the output.

[0040] A blowing air pipe 270 is provided on one side above the riveting groove 221, and a guide rail 400 is provided on the other side. A material box 500 is installed at the output end of the guide rail 400. The air outlet of the blowing air pipe 270 and the feed end of the guide rail 400 are positioned opposite each other on the transverse sides of the riveting groove 221. The blowing air pipe 270 is connected to an external positive pressure air supply mechanism, which can blow the lifted static spring onto the guide rail 400, forming a disengaged blowing and discharging structure. During operation, the blowing air pipe 270 outputs air of appropriate intensity to transfer the product onto the guide rail 400 for output, and finally collects it in the material box 500.

[0041] To ensure smoother and more precise riveting operations and reduce the occurrence of defective products due to insufficient material during riveting, a positioning detection component 260 is provided on the outer side of the riveting groove 221. Specifically, in conjunction with... Figure 3 and Figure 6 The riveting groove 221 has a hollow groove 223 on its side wall. The outer end of the hollow groove 223 is provided with the positioning detection component 260. The positioning detection component 260 includes a sheet metal bracket. The bottom of the sheet metal bracket is locked to the support base 220 by bolts. The top of the sheet metal bracket is provided with a bending part 261. The bending part 261 is provided with a mounting hole. A sensor 262 is installed in the mounting hole. The sensor 262 is specifically a through-beam optical fiber and is used to detect whether the workpiece in the riveting groove 221 is in position.
