Description

Technical Field

[0002] Pins, also known as pins, are the connections between the internal circuit of the integrated circuit and the peripheral circuit. All the pins constitute the interface of the chip. The end of the lead is soldered to form a solder joint with the pad on the printed circuit board. Common chips that require pin bending include transistors.

[0003] Existing bending machines include automatic pin bending machines and manual pin bending machines. Taking the manual pin bending machine as an example, the worker places the transistor at a designated location on the workbench and needs to adjust the position of the transistor to ensure that the transistor is aligned with the pressure rod. Then, the pressure rod is operated to press the transistor into the workbench. The pins of the transistor are bent by setting the limit grooves corresponding to the transistor inside the workbench.

[0004] When using a manual pin bending machine, workers need to manually load the materials and repeatedly adjust the position of the transistor. If the positioning is inaccurate, the pins of the transistor will not be bent up to standard. The lack of a positioning device requires repeated adjustment of the positioning, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0024] Reference Figure 1 and Figure 4 , is the first embodiment of the present utility model, which provides a loading jig for a pin bending machine, including a base 1, an operating table 5 is fixedly connected to the upper surface of the base 1, a positioning component 4 is provided inside the base 1, a feeding component 2 is provided on the upper surface of the base 1, and the positioning component 4 includes two lifting springs 403 fixedly connected to the bottom of the inner cavity of the base 1, the top of the lifting spring 403 is fixedly connected to the lower pressure plate 401, the outer surface of the lower pressure plate 401 is fixedly connected to the lifting plate 402, the upper surface of the lifting plate 402 is fixedly connected to the inclined guide column 405, the outer surface of the inclined guide column 405 is movably connected to the positioning block 404, and the lower surface of the positioning block 404 is slidably connected to the upper surface of the operating table 5.

[0025] Specifically, a slot for bending pins is provided inside the operating table 5, a lifting plate is provided inside the slot, a return spring is provided on the lower surface of the lifting plate, a sliding groove is provided on the outer surface of the base 1 for raising and lowering the lower pressure plate 401, and a square groove is provided inside the operating table 5 for raising and lowering the inclined guide column 405.

[0026] Further, the lower pressing plate 401 is pressed downward, and the lower pressing plate 401 drives the lifting plate 402 to descend, thereby driving the inclined guide column 405 to descend. During the descent of the inclined guide column 405, the positioning block 404 is driven to move on the operating table 5, thereby squeezing and positioning the two sides of the transistor. Then, the lower pressing plate 401 is released, and the lifting plate 402 and the inclined guide column 405 are driven to reset under the action of the lifting spring 403, so that the positioning block 404 releases the squeezing of the two sides of the transistor. Then, the pins of the transistor placed on the operating table 5 are bent by a manual bending machine, and the pins of the transistor are bent through the slot set inside the operating table 5. After the bending is completed, the lifting plate inside the slot drives the transistor to rise under the action of the reset spring, thereby making it convenient for workers to take out the transistor. Example

[0027] Reference Figure 1 、 Figure 2 and Figure 3 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The feeding assembly 2 includes a storage barrel 201 fixedly connected to the upper surface of the base 1. The outer surface of the storage barrel 201 is provided with a limiting groove, and the bottom end of the limiting groove is connected to a rectangular groove. A pushing plate 202 is inserted into the interior of the storage barrel 201, and the end of the pushing plate 202 away from the storage barrel 201 is fixedly connected to a connecting plate 205, and both ends of the connecting plate 205 are hinged with a rotating plate 206. The end of the rotating plate 206 away from the connecting plate 205 is movably connected with a latch 208. The outer surface of the storage barrel 201 is fixedly connected to two limiting frames 203, and the latch 208 slides inside the limiting frame 203. Two compression springs 207 are fixedly connected to the inside of the limiting frame 203, and one end of the compression spring 207 is fixedly connected to the outer surface of the latch 208.

[0028] Specifically, there are three limit grooves on the outer surface of the storage barrel 201. Two abutment plates 3 are fixedly connected to the upper surface of the base 1. The lower surface of the rectangular groove at the bottom end of the limit groove is flush with the upper surface of the operating table 5. The two sides of the rectangular groove are fixedly connected to the limit plates 204. A rectangular opening is provided at the top of the storage barrel 201.

[0029] Further, the connecting plate 205 is pushed, driving the pushing plate 202 to push out a transistor located at the bottom. The connecting plate 205 drives the rotating plate 206 and the latch 208 to slide inside the limit frame 203 and squeeze the compression spring 207. The height of the rectangular groove connected to the bottom end of the limit groove can only allow one transistor to be pushed out. After the transistor is pushed out of the storage barrel 201, it is limited by the two limit plates 204, thereby moving in a straight line. The transistor is continued to be pushed by the pushing plate 202 until one side of the transistor abuts the two abutment plates 3, and at this time, the side of the transistor away from the abutment plate 3 just leaves the limit plate 204. After loosening the connecting plate 205, the plug wire is driven to move in the opposite direction under the action of the compression spring 207, thereby driving the rotating plate 206 to rotate, so that the pushing plate 202 is reset.

[0030] Working principle: When bending the pins of the transistors, the transistors are placed into the storage barrel 201 in the direction of bending through the rectangular opening at the top of the storage barrel 201, and the pins of the transistors are inserted into the limit grooves on the outer surface of the storage barrel 201. When bending is required, the connecting plate 205 is pushed to drive the pushing plate 202 to push out a transistor at the bottom. The connecting plate 205 drives the rotating plate 206 and the latch 208 to slide inside the limit frame 203 and squeeze the compression spring 207. The height of the rectangular groove connected to the bottom of the limit groove can only allow one transistor to be pushed out. After the transistor is pushed out of the storage barrel 201, it is limited by the two limit plates 204, so that it moves in a straight line. The transistor is pushed by the pushing plate 202 until one side of the transistor abuts the two abutment plates 3, and at this time, the side of the transistor away from the abutment plate 3 just leaves the limit plate 204. After loosening the connecting plate 205, the plug wire is driven to move in the opposite direction under the action of the compression spring 207, thereby driving the rotating plate 206. The rotation causes the pushing plate 202 to reset, and the transistor inside the storage barrel 201 falls to wait for the next pin to be bent. The lower pressing plate 401 is pressed downward, and the lower pressing plate 401 drives the lifting plate 402 to descend, thereby driving the inclined guide post 405 to descend. During the descending process of the inclined guide post 405, the positioning block 404 moves on the operating table 5, thereby squeezing and positioning the two sides of the transistor. Then, the lower pressing plate 401 is released, and the lifting plate 402 and the inclined guide post 405 are driven to reset under the action of the lifting spring 403, so that the positioning block 404 releases the squeezing of the two sides of the transistor. Then, the pins of the transistor placed on the operating table 5 are bent by the manual bending machine, and the pins of the transistor are bent through the slot provided inside the operating table 5. After the bending is completed, the lifting plate inside the slot drives the transistor to rise under the action of the reset spring, so that it is convenient for the worker to take out the transistor, and finally the pin bending of the transistor is completed. The material is convenient to load and can be positioned without the need for the worker to manually position it repeatedly.
