Detailed implementation manners

[0020] The following further explains the detailed implementation manners of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these implementation manners is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Combined with Figures 1 to 4A device for trimming the lamp pins of a bulb, as shown, includes a support base 1. A bulb positioning seat 5 is installed at the upper end of the support base 1. A cutting base 2 is arranged between the bulb positioning seat 5 and the support base 1. A lamp pin cutting assembly 3 and a lamp pin positioning assembly 4 are installed on the cutting base 2. The bulb positioning seat 5 is located above the lamp pin cutting assembly 3 and the lamp pin positioning assembly 4. A first boss 16 and a second boss 17 are slidably arranged at one end of the lamp pin positioning assembly 4 close to the lamp pin cutting assembly 3. The thickness of the first boss 16 is less than that of the second boss 17. The upper end faces of the first boss 16 and the second boss 17 are flush. A cutting area is formed below the first boss 16. The lamp pin cutting assembly 3 includes a cutter 14 and a pressure rod 15 that are slidably arranged respectively. A pressure seat 22 is arranged at one end of the pressure rod 15 close to the cutting area. A notch is formed at the bottom of one end of the pressure seat 22 close to the cutting area. The notch is aligned with the cutting area. The cutter 14 is located in the notch of the pressure seat 22. A bulb hole for placing and positioning an automotive bulb is formed in the bulb positioning seat 5. When a cutting operation is required, the automotive bulb is placed in the bulb hole. The pressure seat 22 is slid to tightly press the two lamp pins of the automotive bulb on the first boss 16 and the second boss 17 respectively, and the cutter 14 is inserted into the cutting area. The first boss 16 and the second boss 17 tightly press the two lamp pins of the automotive bulb respectively, preventing the phenomenon that the automotive bulb shakes due to the unevenness of the lamp pin being pressed when only one lamp pin is tightly pressed. In this embodiment, a bulb hole for placing and positioning an automotive bulb is formed in the bulb positioning seat 5. The automotive bulb is inserted into the bulb hole, so that the lamp pins of the automotive bulb are located between the lamp pin cutting assembly 3 and the lamp pin positioning assembly 4, thereby enabling the lamp pins of the automotive bulb to be trimmed, making the lamp pin specifications of each produced automotive bulb the same, and eliminating the need for manual cutting during the subsequent assembly process, improving work efficiency.

[0022] In this embodiment, the lamp pin positioning assembly 4 includes a first guide seat 6 installed on the cutting base 2. A first sliding rod 7 is slidably installed in the first guide seat 6. A first lamp pin positioning head 9 and a second lamp pin positioning head 10 are installed at one end of the first sliding rod 7 close to the bulb positioning seat 5. A first boss 16 is arranged at the end of the first lamp pin positioning head 9. A second boss 17 is arranged at the end of the second lamp pin positioning head 10. By pressing the pressure rod 15 towards the first boss 16 and the second boss 17, the two lamp pins of the automotive bulb are tightly pressed on the first boss 16 and the second boss 17. The two lamp pins are respectively tightly pressed on the first boss 16 and the second boss 17. The tail end of one of the lamp pins is located in the notch, that is, in the cutting area, so as to facilitate the subsequent further cutting of the lamp pin extending into the cutting area by the lamp pin cutting assembly 3.

[0023] It should be noted that the other end of the first sliding rod 7 in this embodiment is connected to a first air cylinder 8, and the first air cylinder 8 is installed on the cutting base 2; the first air cylinder 8 drives the first sliding rod 7 to move, so as to drive the first boss 16 and the second boss 17 to move towards the automotive bulb placed on the bulb positioning seat 5.

[0024] Specifically, the lamp pin cutting assembly 3 in this embodiment further includes a second guiding seat 11 installed on the cutting base 2. A second sliding rod 12 is slidably installed in the second guiding seat 11. A cutting knife 14 is installed at one end of the second sliding rod 12 close to the cutting area. A pressing rod 15 is slidably arranged in the second sliding rod 12; the second sliding rod 12 drives the cutting knife 14 and the pressing rod 15 to move synchronously, so that the pressing seat 22 can preferentially clamp the two lamp pins of the middle automotive bulb. And the pressing rod 15 is a slidable structure in the second sliding rod 12. When the second sliding rod 12 moves further, under the action of elastic force, the pressing rod 15 shrinks and moves in the second sliding rod 12. The second sliding rod 12 drives the cutting knife 14 to move further and relatively protrudes into the notch of the pressing seat 22, so that the cutting knife 14 further cuts into the cutting area, thereby cutting off the lamp pins extending into the cutting area, making the cutting specifications of the lamp pins of each automotive bulb the same and having high cutting efficiency.

[0025] A guiding groove 18 is formed on the upper end surface of the second sliding rod 12 in this embodiment. The pressing rod 15 is slidably arranged in the guiding groove 18. A spring is installed at one end of the pressing rod 15 away from the pressing seat 22. One end of the spring abuts against the pressing rod 15, and the other end abuts against the second sliding rod 12. A strip-shaped hole 21 is also formed on the pressing rod 15. The strip-shaped hole 21 is arranged along the length direction of the pressing rod 15. A limiting post 20 is installed in the guiding groove, and the limiting post 20 passes through the strip-shaped hole 21. A spring groove 19 is formed on the pressing rod 15, and part of the spring is arranged in the spring groove 19. The spring groove 19 is used for positioning and installing the spring to make the position of the spring more stable; enabling the pressing rod 15 to slide in the second sliding rod 12, so that the pressing seat 22 can first clamp the lamp pins. After the second sliding rod 12 moves further, the contraction stroke of the pressing rod 15 is limited by the strip-shaped hole 21, thereby limiting the length of the cutting knife 14 protruding outwards in the notch of the pressing seat 22 and preventing the cutting knife 14 from cutting too deep and colliding with the inner wall end of the cutting area. For example, when the pressing seat 22 first presses and clamps the lamp pins, the second sliding rod 12 and the limiting post 20 move further at the same time. During the contraction process of the pressing rod 15, the limiting post 20 moves in the strip-shaped hole 21, and the cutting knife 14 protrudes outwards and cuts in the notch of the pressing seat 22 until the limiting post 20 presses against the strip-shaped hole 21. At this time, the cutting action has been completed. Even if the second sliding rod 12 continues to move and further applies force, since the limiting post 20 has pressed against the pressing rod 15, there will be no relative movement between the cutting knife 14 and the pressing seat 22. At this time, the cutting knife 14 cannot further protrude, thereby limiting the protruding length of the cutting knife 14.

[0026] It should be noted that the other end of the second slide bar 12 in this embodiment is connected to a second air cylinder 13, and the second air cylinder 13 is installed on the cutting base 2; the second slide bar 12 can be driven to move by the second air cylinder 13. A top cover can be provided on the upper end of the second guide seat 11 to stably hold the pressure rod 15 and the spring inside, prevent them from detaching, and facilitate the replacement of the pressure rod 15.

[0027] In some embodiments, the cutter 14 and the second slide bar 12 can also be connected through a separable structure, such as bolt connection. The first lamp pin positioning head 9 and the second lamp pin positioning head 10 can also be jointly installed on a connecting seat, and the connecting seat is bolted to the first slide bar 7 to facilitate the replacement of the first lamp pin positioning head 9 and the second lamp pin positioning head 10 with different thicknesses to adapt to cuts of different sizes.

[0028] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
