Technical Field

[0001] This utility model relates to the field of toggle switch production equipment technology, and in particular to a spring assembly module for a toggle switch production line. Background Technology

[0002] In the assembly and production process of toggle switches, springs need to be installed on levers. If the traditional manual separation method is used, the springs need to be cut out one by one from the strip using a stamping tool, and then the springs need to be pressed onto the levers one by one to achieve the assembly. This is not only laborious and time-consuming, which greatly affects the production efficiency, but also the quality of manually assembled products is not high, affecting the product qualification rate. Utility Model Content

[0003] The purpose of this invention is to provide a spring assembly module for a toggle switch production line. This invention can replace manual labor in assembling the spring and lever of the toggle switch, and has the advantages of high production efficiency and high pass rate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spring assembly module for a toggle switch production line, including a frame, on which a punching assembly mechanism and a spring strip conveying mechanism are provided;

[0005] The blanking assembly mechanism includes a blanking bracket, a pressing cylinder mounted on the blanking bracket, a connecting seat mounted on the extended end of the pressing cylinder, an upper knife seat mounted on the connecting seat, a cutting tool mounted on the upper knife seat, and a lever carrier mounted below the cutting tool for placing the lever assembly.

[0006] The spring sheet conveying mechanism includes a transmission track and a material feeding assembly for moving the spring sheet along the transmission track. The extension direction of the transmission track is provided with a flow channel for the product material. A lower knife holder is provided on the transmission track. The lower knife holder is located between the cutting tool and the lever carrier. The lower knife holder is provided with a cutting edge for the cutting tool to pass through and press the spring sheet onto the lever assembly.

[0007] By adopting the above technical solution, the spring strip is placed on the flow channel of the transmission track. The spring strip is driven forward by the feeding assembly. When the spring strip is conveyed to the blanking mechanism area, the pressing cylinder of the blanking mechanism drives the connecting seat downward, the connecting seat drives the upper knife seat downward, and the upper knife seat drives the cutting tool downward to blank the spring strip. The blanked spring strip passes through the cutting edge of the lower knife seat and is pressed onto the lever assembly, thus completing the blanking and assembly of multiple spring strips at one time. This can replace manual assembly of the spring strips and levers of the toggle switch, and has the advantages of high production efficiency and high pass rate.

[0008] The present invention is further configured such that the upper tool holder is provided with a vacuum chamber, the side of the upper tool holder is provided with two vacuum ports for installing vacuum connectors, the tool is installed at the bottom of the upper tool holder, and the bottom of the upper tool holder is provided with a first vacuum hole communicating with the vacuum chamber, and the upper tool is provided with a second vacuum hole communicating with the first vacuum hole through a vertical line.

[0009] By adopting the above technical solution, the individual spring pieces after punching are vacuum-held and thus accurately and stably pressed onto the lever assembly.

[0010] The present invention is further configured such that a plurality of lower guide holes are provided through the bottom of the cutting tool, and an upper guide hole is provided at one end of the lower guide holes near the upper tool holder. A limiting step is formed between the upper guide holes and the lower guide holes. A pressing block for pressing the spring strip is provided through the lower guide holes. A limiting flange is provided at one end of the pressing block that extends into the upper guide hole and forms a stroke limit with the limiting step when moving downward. An elastic element that provides downward preload to the pressing block is also provided in the upper guide hole.

[0011] By adopting the above technical solution, when punching the spring strip, the upper knife holder drives the knife to descend, the pressure block first presses the elastic strip, and then the knife continues to descend until the spring strip is punched off. This can ensure the stable positioning of the spring strip when punching the spring strip, which is more conducive to the cutting of the spring strip.

[0012] The present invention is further configured such that the cutting tool includes multiple cutting blade units connected side by side, and the upper guide hole and the lower guide hole are provided between every two connected cutting blade units for installing the pressure block.

[0013] By adopting the above technical solution, the disassembly and assembly of the pressure block is greatly facilitated.

[0014] The present invention is further configured such that a plurality of C-shaped connectors are connected to the side of the upper tool holder by fasteners, the bottom of the C-shaped connectors extends inward to support the transmission rail, and there is an movable gap between the transmission rail and the upper tool holder.

[0015] By adopting the above technical solution, an movable gap is set between the transmission track and the upper knife holder to provide space for relative movement between the two, which can ensure that the spring strip is pressed tightly before the spring is punched.

[0016] The present invention is further provided in that the frame is provided with a plurality of guide posts extending vertically, and the upper tool holder is provided with a plurality of guide sleeves that cooperate with the guide posts.

[0017] By adopting the above technical solution, the stability of the upper tool holder's up-and-down movement can be improved.

[0018] The present invention is further configured such that the feeding assembly includes a feeding motor mounted on a transmission track and a plurality of ratchet wheels linked to the motor shaft of the feeding motor for engaging with positioning holes on the spring strip.

[0019] By adopting the above technical solution, the ratchet is driven by the feeding motor to rotate, which drags the spring strip forward stably and the stroke control is precise.

[0020] The present invention is further provided that a cover plate is installed on the transmission track, and the cover plate is provided with a through hole for the ratchet to pass through.

[0021] By adopting the above technical solution, the spring strip material can be limited, so that it is always positioned in the flow channel during stable transmission. Attached Figure Description

[0030] Example: As attached Figures 1-6 The spring assembly module of the toggle switch production line shown includes a frame 1, on which a punching assembly mechanism 2 and a spring strip conveying mechanism 3 are provided;

[0031] The blanking assembly mechanism 2 includes a blanking bracket 4, a pressing cylinder 5 disposed on the blanking bracket 4, a connecting seat 6 disposed on the extended end of the pressing cylinder 5, an upper knife seat 7 mounted on the connecting seat 6, a cutting tool 8 mounted on the upper knife seat 7, and a lever carrier 9 disposed below the cutting tool 8 for placing the lever assembly.

[0032] The spring sheet conveying mechanism 3 includes a transmission track 10 and a material feeding assembly 11 for moving the spring sheet along the direction of the transmission track 10. The extension direction of the transmission track 10 is provided with a flow channel 12 for the product material. The transmission track 10 is provided with a lower knife holder 13, which is located between the cutter 8 and the lever carrier 9. The lower knife holder 13 is provided with a cutting edge 14 for the cutter 8 to pass through and press the spring sheet onto the lever assembly.

[0033] The spring strip is placed on the flow channel 12 of the transmission track 10. The spring strip is driven forward by the feeding assembly 11. When the spring strip is conveyed to the blanking mechanism area, the pressing cylinder 5 of the pressing mechanism drives the connecting seat 6 downward, the connecting seat 6 drives the upper knife seat 7 downward, and the upper knife seat 7 drives the cutter 8 downward to blank the spring strip. The blanked spring strip passes through the cutting edge 14 of the lower knife seat 13 and is pressed onto the lever assembly, thus completing the blanking and assembly of multiple spring strips at one time. It can replace manual assembly of the spring strips and levers of the toggle switch, and has the advantages of high production efficiency and high pass rate.

[0034] As attached Figures 3-6As shown, the upper tool holder 7 has a vacuum chamber 15 inside, and two vacuum ports 16 for installing vacuum connectors are provided on the side of the upper tool holder 7.

[0038] As attached Figure 3 As shown, the upper cutter holder 7 has multiple U-shaped connectors 26 connected to its side by fasteners. In this embodiment, the fasteners are screws. The bottom of each U-shaped connector 26 extends inward to support the transmission rail 10, and a movable gap 27 is provided between the transmission rail 10 and the upper cutter holder 7. The movable gap 27 between the transmission rail 10 and the upper cutter holder 7 provides space for relative movement between the two, ensuring that the spring strip is first pressed against the material before the spring strip is punched.

[0039] As attached Figure 3 and attached Figure 5As shown, the frame 1 is also provided with a plurality of vertically extending guide posts 28, and the upper tool holder 7 is provided with a plurality of guide sleeves 29 that cooperate with the guide posts 28. This design can improve the stability of the upper tool holder 7's vertical movement.

[0040] As attached Figure 2 As shown, the feeding assembly 11 includes a feeding motor 30 mounted on the transmission track 10 and multiple ratchet wheels 31 linked to the motor shaft of the feeding motor 30 for engaging with positioning holes on the spring strip. The feeding motor 30 drives the ratchet wheels 31 to rotate, dragging the spring strip forward stably with precise stroke control.

[0041] As attached Figure 2 As shown, a cover plate 32 is also installed on the transmission track 10, and the cover plate 32 is provided with a through hole 33 for the ratchet 31 to pass through. This design can limit the movement of the spring strip, so that it is always positioned in the flow channel 12 during stable transmission.
