Description

Technical Field

[0001] This utility model belongs to the field of cutting device technology, and relates to a pin cutting device for extending pin devices. Background Technology

[0002] A pin trimming device for extended pin devices is a specialized tool used to trim the pin length of extended pin devices, ensuring neat, burr-free cut edges that can be soldered onto the PCB board of the product design. It is suitable for pin trimming of extended pin devices.

[0003] Currently, the leads of domestically produced extended-lead devices are relatively long and cannot be directly used for PCB soldering and assembly, requiring lead trimming. However, the lead trimming process cannot be completed during the device manufacturer's production process; the unit that needs to solder the device must trim it according to the PCB design. The current trimming method uses tools such as diagonal pliers to trim the device leads according to the comparison length, which has disadvantages such as poor trimming length consistency and low efficiency. Utility Model Content

[0004] (a) Purpose of the utility model The purpose of this invention is to provide a pin trimming device for extended pin devices, in order to solve the problems mentioned in the background art, such as inconsistent pin lengths and low efficiency caused by using diagonal pliers to trim the pins of extended pin devices.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides a pin trimming device for extended pin devices, which includes a base 1, a guillotine holder 2 and a blade holder 6 mounted on the base 1; one end of the guillotine 3 is hinged to the guillotine holder 2, and the other end is mounted with a handle 4; a blade 5 is mounted on the blade holder 6; the guillotine 3 is located on one side of the blade 5.

[0006] Furthermore, the base is provided with three opening slots. One opening slot is used to fix the guillotine holder 2, and the other two opening slots are parallel and on which the blade holder 6 is installed.

[0007] Furthermore, the thickness of the blade 5 is determined according to the pin cutting dimensions.

[0008] Furthermore, the mounting position of the tool holder 6 on the two opening slots is adjustable.

[0009] Furthermore, one side of the blade 5 comes into contact with one side of the guillotine 3.

[0010] Furthermore, the other end of the guillotine 3 is connected to a support body 7 via a threaded connection. When the guillotine 3 is lowered, the lower end of the support body 7 contacts and supports the base 1.

[0011] Furthermore, the guillotine 3 is made of Cr12MoV material, and its heat treatment hardness is in the range of 58 to 62 HRC.

[0012] Furthermore, the blade 5 is made of Cr12MoV material, and its heat treatment hardness is in the range of 58 to 62 HRC.

[0013] Furthermore, the top of the guillotine holder 2 is provided with a slot and a hinged through hole. One end of the guillotine 3 is placed into the slot, and a screw is passed through the hinged through hole and the through hole at one end of the guillotine 3 to hinge one end of the guillotine 3 to the guillotine holder 2. The other end of the guillotine 3 is fixed to the handle 4 with a screw. One threaded end of the support body 7 is screwed into the screw hole on the side of the guillotine 3 that fixes the handle 4. The blade 5 is fixed to the side of the blade holder 6 with 3 screws.

[0014] Furthermore, the guillotine holder 2 and the blade holder 6 are connected to the base 1 by screws; the blade 5 is connected to the blade holder 6 by screws.

[0015] (III) Beneficial Effects The lead trimming device for extended lead devices provided by the above technical solution has the following beneficial effects: (1) The pin trimming device enables rapid trimming of the pins of extended pin devices and ensures that the pin length is consistent after trimming without damaging the component body or the root of the pin.

[0016] (2) By configuring blades of different thicknesses, the remaining pin length of the device after cutting is guaranteed. It has strong adaptability and can adapt to the pin cutting of various types of extended devices to meet the soldering requirements of various PCBs.

[0017] (3) All parts not involved in this device are the same as or can be implemented using existing technology. The structure of this utility model is scientific and reasonable, safe and convenient to use. The application of this cutting device can realize a single person's fast cutting operation, which greatly improves production efficiency. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the assembled structure of the pin trimming device for extended pin devices according to this utility model. Figure 2 As an example of an extended pin device, extended pin devices also include other devices with two rows of pins and pins extending horizontally from both sides of the device body, such as SOP packaged devices. Detailed Implementation

[0019] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Reference Figure 1 and Figure 2As shown, the pin trimming device for extended pin devices in this embodiment includes a base 1. The base 1 has three slots in the middle for screws to pass through and fix the guillotine holder 2 and the blade holder 6. The top of the guillotine holder 2 has a slot and a hinged through hole. One end of the guillotine 3 is placed in the slot, and the screw is passed through the hinged through hole and the through hole at one end of the guillotine 3 to hinge one end of the guillotine 3 to the guillotine holder 2. The other end of the guillotine 3 is fixed to the handle 4 with a screw. The threaded end of the support body 7 is screwed into the screw hole on the side of the guillotine 3 where the handle 4 is fixed. The blade 5 is fixed to the side of the blade holder 6 with three screws. The guillotine 3 is made of Cr12MoV material and has been heat-treated to a hardness in the range of 58 to 62 HRC.

[0021] The blade 5 is made of Cr12MoV material and has been heat-treated to a hardness in the range of 58 to 62 HRC.

[0022] In this invention, the pins of the extended pin device can be cut into different lengths by controlling the thickness of the blade 5.

[0023] The working principle and usage process of this utility model are as follows: Before use, determine the reserved size of the extended pin device to be cut, and process the blade 5 of corresponding thickness according to the size; fix the blade 5 on the blade holder 6, and place the support body 7 in contact with the base 1 to support the guillotine 3. Adjust the position of the blade holder 6 on the base 1 so that the blade 5 just contacts the guillotine 3. At this time, fix the blade holder 6 on the base 1; when using, lift the handle 4 to separate the guillotine 3 from the blade 5, place the main body of the device facing down, place the pin of the device on the side to be cut on the blade 5, and keep the side of the device in close contact with the blade 5. Hold the handle 4 and lower the guillotine 3. The pin of the device is then cut by the guillotine 3 and the blade 5 together.

[0024] Using this invention for device pin trimming ensures consistent pin lengths after trimming and significantly improves trimming efficiency compared to the current method of using diagonal pliers. This invention is easy to process, simple to assemble, and convenient to maintain.
