[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] Example
[0027] Please see Figure 1-4 This utility model provides a light-emitting diode lead bending device, including a base 1 and a turntable 2. The bottom of the turntable 2 is provided with multiple connecting rods 201. The base 1 is provided with an annular groove 101. The connecting rods 201 are slidably disposed in the annular groove 101. The turntable 2 is provided with multiple sets of placement slots 3 for placing diodes.
[0028] A transmission groove 4 is provided in the middle of the turntable 2. A downward pressure rod 401 is installed through the transmission groove 4. A sleeve 402 is fixedly connected to the base 1. The downward pressure rod 401 is embedded in the sleeve 402 by a spring. A pressure head assembly 5 is fixedly connected to the top of the downward pressure rod 401.
[0029] A guide block 403 is elastically connected to the outer peripheral wall of the pressure rod 401. A guide groove is provided on the inner peripheral wall of the transmission groove 4. The guide block 403 slides against the guide groove. The guide groove is composed of multiple straight segments 404 and inclined segments 405. The top of the inclined segment 405 is connected to the top of the straight segment 404 on one side, and the bottom of the inclined segment 405 is connected to the bottom of the straight segment 404 on the other side. A pad 406 is provided at the connection between the bottom of the inclined segment 405 and the straight segment 404. The pad 406 is thickened from top to bottom.
[0030] Specifically: The diode is placed in the placement slot 3, and the pressure rod 401 is controlled to move down. The pressure rod 401 drives the pressure head assembly 5 to move synchronously, thereby realizing the bending of the diode leads.
[0031] During the downward movement of the pressure rod 401, the guide block 403 moves straight down along one of the straight segments 404 to achieve a bending action, and the guide block 403 can elastically pass over the pad block 406.
[0032] During the upward reset of the pressure rod 401, while the guide block 403 moves upward from the straight section 404 to the bottom inlet of the inclined section 405, the pressure head assembly 5 leaves the placement slot 3 to avoid affecting the rotation of the turntable 2. Then, the guide block 403 enters the inclined section 405 under the obstruction of the pad block 406, and then moves upward in the inclined section 405, thereby controlling the rotation of the turntable 2 and realizing the change of the position of the placement slot 3. Finally, the guide block 403 enters the adjacent straight section 404 and continues to move upward.
[0033] It is understandable that by alternating the circumferential direction of multiple placement slots 3, various working modes can be achieved, as follows:
[0034] First: Single-person operation, one hand controls the up and down movement of the pressure lever 401, and the other hand replaces the pressed diode while the pressure lever 401 moves up;
[0035] Second: Multiple people can operate the device. One person can control the up and down movement of the pressure rod 401, while another person or multiple people can replace the diodes near the circumference of the turntable 2.
[0036] This provides multiple ways to bend diodes, suitable for both factory workers and home workers who undertake outsourcing. It has a simple structure, is easy to operate, and is highly efficient.
[0037] The placement groove 3 includes a head groove 301, a middle groove 302 and a tail groove 303. The pressure head assembly 5 includes a connecting plate 501, a pressure head 502 and a middle pressure block 503. One end of the connecting plate 501 is fixedly connected to the outer wall of the lower pressure rod 401, and the other end of the connecting plate 501 is fixedly connected to the pressure head 502. The middle pressure block 503 is elastically connected to the pressure head 502. The middle groove 302 is provided with a support block 507.
[0038] The central slot 302 is internally threaded with a support post 304. The top of the support post 304 is threadedly connected to the bottom of the support block 507. In this configuration, the height of the support block 507 can be finely adjusted by rotating the support block 507 and the support post 304 a certain number of times, thereby improving the quality of pin bending and preventing the pin from being suspended.
[0039] The side wall of the pressure head 502 is provided with a sliding groove 504, and the outer wall of the middle pressure block 503 is fixedly connected with a slider 505. The slider 505 is slidably disposed in the sliding groove 504, and the slider 505 is elastically disposed in the sliding groove 504 by a spring. In this configuration, relative sliding can occur between the middle pressure block 503 and the pressure head 502.
[0040] Specifically: The diode head is placed in the arc-shaped head slot 301, and the pins extend into the middle slot 302 and the tail slot 303. The pad 406 in the middle slot 302 supports the pin head.
[0041] The pressure head 502 and the middle pressure block 503 move down synchronously. The middle pressure block 503 squeezes the pin head on the support block 507. Then the pressure head 502 continues to move down and bends the pin tail. The pin is bent into the tail groove 303.
[0042] The support block 507 and the middle pressure block 503 can stabilize the position of the pin head, prevent the diode head from tilting up, and improve the bending quality.
[0043] A limiting strip 506 is fixedly connected to the slider 505, and a strip-shaped limiting groove is opened in the slide groove 504. The limiting strip 506 is slidably disposed in the limiting groove.
[0044] A handle 6 is fixedly connected to the top of the pressure rod 401, which allows for easy operation of moving the pressure rod 401 up and down.
[0045] Working principle: The diode head is placed in the arc-shaped head slot 301, and the lead extends into the middle slot 302 and the tail slot 303. The pad 406 in the middle slot 302 supports the lead head. Then, the pressing rod 401 is controlled to move down. The pressing rod 401 drives the pressing head 502 and the middle pressing block 503 to move down synchronously. The middle pressing block 503 squeezes the lead head on the support block 507. Then the pressing head 502 continues to move down and bends the tail of the lead. The lead is bent into the tail slot 303.
[0046] During the downward movement of the pressure rod 401, the guide block 403 moves straight down along one of the straight segments 404 to achieve a bending action, and the guide block 403 can elastically pass over the pad block 406.
[0047] During the upward reset of the pressure rod 401, while the guide block 403 moves upward from the straight section 404 to the bottom inlet of the inclined section 405, the pressure head assembly 5 leaves the placement slot 3 to avoid affecting the rotation of the turntable 2. Then, the guide block 403 enters the inclined section 405 under the obstruction of the pad block 406, and then moves upward in the inclined section 405, thereby controlling the rotation of the turntable 2 and realizing the change of the position of the placement slot 3. Finally, the guide block 403 enters the adjacent straight section 404 and continues to move upward.
[0048] By alternating the circumferential arrangement of multiple placement slots 3, various methods can be provided for bending diodes. This method is suitable for both factory workers and home workers who undertake outsourcing. It features a simple structure, convenient operation, and high efficiency.
