Description

Technical Field

[0001] The utility model relates to the field of electronic component processing equipment, in particular to an automatic pin cutting mechanism. Background Art

[0002] During the production of certain electronic components, it's often necessary to partially trim the pins of these components. This facilitates the insertion and soldering of these components onto various circuit boards, and eliminates the need to trim excessively long pins after soldering, thereby improving the efficiency and automation of circuit board processing. Therefore, the pin trimming process is crucial for the subsequent use of these components. A key consideration during this process is how to effectively and accurately trim the pins. This precision directly impacts the efficiency of subsequent use, as well as the efficiency and automation of the entire circuit board processing process, and can profoundly impact the quality of the circuit boards. Furthermore, since the distance and shape requirements for pins when mounting electronic components onto various circuit boards vary depending on the appliance, circuit, and circuit board, and electronic component production can only be performed according to specific standards, the pin trimming process must be able to tailor the pin lengths required to ensure that these components are easily accessible and meet the diverse needs of customers.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] The present invention provides an automatic pin cutting mechanism for cutting the pins of electronic components. The mechanism includes a base 10, a fixed mold assembly 20, a movable mold assembly 30, and a piston driver 40 disposed on the base 10. The base 10 is further provided with a receiving chamber 13 for accommodating the piston driver 40 and an air passage 14 for connecting the receiving chamber 13. The air passage 14 is connected to an external air source to provide driving force for the piston driver 40. The movable mold assembly 30 is connected to the output end of the piston driver 40, and the fixed mold assembly 20 is disposed on the side of the movable mold assembly 30 away from the piston driver 40. The present invention replaces the cylinder drive of the prior art with a piston drive, resulting in a simple structure, a small overall footprint, and low cost.

[0034] In this embodiment, a vertical wall 11 and a support seat 12 are further provided on the base 10 . The accommodating cavity 13 is provided on the vertical wall 11 , and the support seat 12 is provided on one side of the accommodating cavity 13 .

[0035] The upper end of the support base 12 defines a first slot 121, within which the movable mold assembly 30 moves. Two first guide posts 122 are positioned side by side on the end of the first slot 121 near the fixed mold assembly 20. Guide rails 31 are positioned side by side at the bottom of the movable mold assembly 30, engaging with the first guide posts 122. The first guide posts 122 move relative to each other within the guide rails 31. Specifically, the first guide posts 122 are secured within the first slot 121. The piston driver 40 drives the movable mold assembly 30 forward within the first slot 121, causing the guide rails 31 to move forward. At this point, the first guide posts 122 move relative to each other within the guide rails 31.

[0036] In this embodiment, the fixed mold assembly 20 includes a positioning seat 21 arranged on the base 10, a first positioning member 22 arranged on one side of the positioning seat 21, and a second positioning member 23 arranged above the movable mold assembly 30. The movable mold assembly 30 is provided with a cutter 32 on the side facing the fixed mold assembly 20, and a second slide groove 34 is opened at the top of the movable mold assembly 30. The second positioning member 23 is connected to the second slide groove 34.

[0037] In this embodiment, a limit slot 341 is defined within the second chute 34, and a second guide post 231 is disposed at the lower end of the second positioning member 23. The piston driver 40 drives the movable mold assembly 30 forward within the first chute 121, while the second positioning member 23 remains stationary relative to the limit slot 341. At this point, the second guide post 231 moves relative to the limit slot 341. When the second guide post 231 moves relative to the front end of the limit slot 341, the piston driver 40 drives the movable mold assembly 30 further forward within the first chute 121, driving the second positioning member 23 forward. When the movable mold assembly 30 has advanced to its maximum distance, the first and second positioning members 22 and 23 cooperate to form a pin-cutting portion, where the electronic component is positioned by the first and second positioning members 22 and 23. Simultaneously, the cutter 32 removes any excessively long leads from the electronic component.

[0038] Specifically, the first positioning member 22 is a pressure block provided on one side of the positioning seat 21 , and the first positioning member 22 is a pressure plate connected to the second sliding groove 34 .

[0039] A limit block 33 extends from the front end of the cutter 32 to prevent the movable mold assembly 30 from being overdriven and damaging the fixed mold assembly 20 .

[0040] In this embodiment, the fixed mold assembly 20 further includes a fixing plate 24, which is disposed above the second positioning member 23 and is screwed to the support base 12. The fixing plate 24 in this embodiment prevents the second positioning member 23 from being misaligned, ensuring that the second positioning member 23 is always positioned within the second chute 34, thereby ensuring accurate positioning of the cutting foot.

[0041] In this embodiment, the automatic pin cutting mechanism further includes a waste guide groove 50 , which is provided between the fixed mold assembly 20 and the movable mold assembly 30 to collect waste produced during the pin cutting process of the electronic components.

[0042] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
