Description

Technical Field

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

[0002] In the assembly and production process of toggle switches, the leads of the product strip need to be cut and bent to separate the product from the product strip. If the traditional manual separation method is used, tools such as tweezers, clamps, and hammers are needed to assist in the assembly. This is not only laborious and time-consuming, but also greatly affects the production efficiency. In addition, the quality of manually assembled products is not high, which affects the product qualification rate. Utility Model Content

[0003] The purpose of this invention is to provide a cutting and bending module for a toggle switch production line. This invention can replace manual cutting and bending of toggle switch product strips, and has the advantages of high production efficiency and high pass rate.

[0005] The product conveyor belt includes a conveyor track and a feeding assembly for moving the product conveyor belt along the extension direction of the conveyor track. The extension direction of the conveyor track is provided with a flow channel for the product conveyor belt.

[0006] The cutting and bending mechanism includes a stamping bracket, a pressing cylinder mounted on the stamping bracket, a pressing seat mounted on the extended end of the pressing cylinder, and multiple sets of cutting and bending assemblies mounted on the pressing seat.

[0007] By adopting the above technical solution, the product strip is placed on the flow channel of the conveyor track. The product strip is driven forward by the feeding assembly. When the product strip is conveyed to the cutting and bending mechanism area, the pressing cylinder of the stamping assembly drives the lower pressing seat downward. Multiple sets of cutting and bending assemblies descend, where the pressing block clamps and positions the product, the terminal pressing block clamps and positions the terminal, and the cutting and bending block acts on the product pins to bend them and separate them from the terminals, completing the separation of multiple toggle switch products in one operation. This can replace manual cutting and bending operations on toggle switch product strips, and has the advantages of high production efficiency and high pass rate.

[0008] The present invention is further configured such that the lower pressure seat includes an upper mounting plate and a lower mounting plate connected together, the lower mounting plate is provided with an opening for the cutting and bending assembly to pass through, the cutting and bending block is provided with a first limiting part, the first limiting part is sandwiched between the upper mounting plate and the lower mounting plate, the lower end of the upper mounting plate is provided with a first sliding groove and a second sliding groove for the pressure block and the terminal pressure block to move vertically, and both the first sliding groove and the second sliding groove are provided with elastic elements for providing pre-tightening force to the pressure block and the terminal pressure block, the pressure block is provided with a second limiting part at the position of the first sliding groove for abutting against the upper end of the lower mounting plate to form a limiting when it moves downward, and the terminal pressure block is provided with a third limiting part at the position of the second sliding groove for abutting against the upper end of the lower mounting plate to form a limiting when it moves downward.

[0009] By adopting the above technical solution, the assembly of cutting and bending components can be realized. The structure is simple and reliable, which is conducive to the initial assembly and subsequent maintenance operations.

The pin groove is provided with a rib with a trapezoidal cross-section, and the bottom of the cutter bending block is provided with a relief groove that matches the shape of the rib.

[0011] By adopting the above technical solution, when the cutting and bending block presses down, it presses the pin part of the product into the pin groove, causing the part to be torn apart from the terminal. When the rib in the pin groove matches the relief groove at the bottom of the cutting and bending block, the bending process of the pin is realized. The cutting and bending processes are carried out simultaneously, which greatly improves the processing efficiency.

[0012] The present invention is further configured such that the transmission track is provided with a plurality of guide posts extending vertically, and the lower pressure seat is provided with a plurality of guide sleeves that cooperate with the guide posts.

[0030] The cutting and bending mechanism 3 includes a stamping bracket 7, a pressing cylinder 8 disposed on the stamping bracket 7, a pressing seat 9 disposed on the extended end of the pressing cylinder 8, and multiple sets of cutting and bending assemblies 10 mounted on the pressing seat 9. The cutting and bending assembly 10 includes a pressing block 11 located in the middle for pressing the product, terminal pressing blocks 12 located on both outer sides for pressing the terminals, and a cutting and bending block 13 disposed between the pressing block 11 and the terminal pressing block 12. The cutting and bending block 13 is fixedly mounted on the pressing seat 9, and the pressing block 11 and the terminal pressing block 12 are mounted on the pressing seat 9 and can move up and down relative to the cutting and bending block 13.

[0031] The product strip is placed on the flow channel 6 of the conveyor track 4. The product strip is driven forward by the feeding assembly 5. When the product strip reaches the cutting and bending mechanism 3 area, the pressing cylinder 8 of the stamping assembly drives the pressing seat 9 downwards. Multiple sets of cutting and bending assemblies 10 descend, where the pressing block 11 presses the product for positioning, the terminal pressing block 12 presses the terminal for positioning, and the cutting and bending block 13 acts on the product pins to bend them and separate them from the terminals, completing the separation of multiple toggle switch products in one operation. This method can replace manual cutting and bending operations on toggle switch product strips, offering advantages such as high production efficiency and high pass rate.

[0032] As attached Figures 3-5As shown, the lower pressure seat 9 includes an upper mounting plate 14 and a lower mounting plate 15 connected together, which can be connected together by screws.

The lower end of the upper mounting plate 14 is provided with a first sliding groove 18 and a second sliding groove 19 for the pressure block 11 and the terminal pressure block 12 to move vertically, and both the first sliding groove 18 and the second sliding groove 19 are provided with An elastic element 35 is provided to provide preload to the pressure block 11 and the terminal pressure block 12. The elastic element 35 can be a spring. The spring acting on the pressure block 11 is a linear spring with low pressure, while the spring acting on the terminal pressure block 12 is a die spring with higher pressure. The pressure block 11 is provided with a second limiting part 20 located in the first slide groove 18 for abutting against the upper end of the lower mounting plate 15 to limit its downward movement. The terminal pressure block 12 is provided with a third limiting part 21 located in the second slide groove 19 for abutting against the upper end of the lower mounting plate 15 to limit its downward movement.

The pin groove 24 contains a trapezoidal rib 25, and the bottom of the cutting and bending block 13 has a relief groove 26 that matches the shape of the rib 25. When the cutting and bending block 13 presses down, it presses the product pin into the pin groove 24, causing the pin to be torn apart from the terminal. When the rib 25 in the pin groove 24 engages with the relief groove 26 at the bottom of the cutting and bending block 13, the pin is bent. The cutting and bending processes are performed simultaneously, greatly improving processing efficiency.

The product strip that is processed by the cutting and bending mechanism 3 finally enters the discharge port 33 and is guided to the corresponding area by the guide plate 34, so as to realize the centralized collection of the product.

[0036] As attached Figure 1 As shown, the feeding assembly 5 includes a feeding motor 29 mounted on the transmission track 4 and multiple ratchet wheels 30 connected to the motor shaft of the feeding motor 29 for engaging with positioning holes on the product conveyor belt.
