[0002] The functional modules of electronic devices usually include circuit boards and components soldered on the circuit boards. In order to enable the components to meet the soldering requirements, before soldering the components on the circuit board, it is necessary to process and trim the pins of the components. In order to enable the plug-in machine to complete the work efficiently, the traditional method is to put the electronic components into a foot trimming machine for pretreatment. However, when dealing with a large number of components, they are often processed one by one after being sorted.

[0027] The above main component symbols are further described in detail for the present utility model in combination with the accompanying drawings and specific embodiments. Specific embodiments

[0028] The present utility model will be described in detail below in combination with the accompanying drawings.

[0029] Please refer to Figures 1-5 , this embodiment provides a base trimming device for a vertical plug-in machine, which includes a load-bearing platform 2, a bracket I 1, a bracket II 3 located below the bracket I 1, an outer shell 4 fixedly installed at the position of the bracket I 1 facing the bracket II 3, two groups of rotary joints 7 symmetrically installed along the longitudinal axis on the load-bearing platform 2, two groups of fixtures 8 located inside the outer shell 4, a bent-angle base 5 fixedly installed on the corresponding rotary joint 7, two groups of tool holders 9 fixedly installed on the bracket II 3, and blades 6 detachably installed on the corresponding tool holders 9.

[0030] A slot is opened at the position of the outer shell 4 facing the bracket II 3, and the fixture 8 is accommodated in the slot. A hydraulic device for driving the two groups of fixtures 8 to move horizontally is provided inside the outer shell 4. In this embodiment, the two groups of fixtures 8 are controlled by the hydraulic device to move towards each other, so as to clamp the electronic components to be processed. Sawteeth are opened on the side walls of the two groups of fixtures 8 close to each other. Based on the sawteeth, the friction force of the clamping surface of the electronic components is increased, thereby improving the stability of clamping.

[0031] The rotary joint 7 is located between the bracket I 1 and the bracket II 3. The bent-angle base 5 rotates under the action of the corresponding rotary joint 7, and the rotation angle range of the bent-angle base 5 is from zero degree to ninety degrees.

[0032] The bent-angle base 5 is composed of two clamping plates. The two clamping plates are arranged in parallel, and knife grooves are opened through the clamping plates. When the two groups of bent-angle bases 5 are perpendicular to the longitudinal axis, the positions of the knife grooves correspond to the blades 6. In this embodiment, when the blade 6 becomes dull due to wear or rust, etc., the blade 6 can be removed from the tool holder 9 for replacement.

[0033] Linear motor modules 10 are provided on both sides of the bracket I 1 and the bracket II 3. The bracket I 1 is fixedly connected between the slide tables of the two groups of corresponding linear motor modules 10, and the bracket II 3 is fixedly connected between the slide tables of the two groups of corresponding linear motor modules 10.

[0034] The pin-cutting device of this embodiment works as follows: When the electronic component moves from the feeding end of the conveyor belt along the conveyor belt to below the fixture 8 and the pins of the electronic component pass through between the two side bent-angle bases 5, the stepping motor in the linear motor module 10 that controls the support I1 drives the lead screw to rotate, the slide table moves downward, driving the support I1 to move downward. After the hydraulic device drives the fixture 8 to clamp the electronic component, the support I1 moves upward so that the electronic component no longer contacts the conveyor belt. Subsequently, the linear motor module 10 drives the support II3 to move upward, and the blade 6 passes through the knife slot on the fixture 8 to cut off the redundant pins and then the blade 6 resets. Then, the bent-angle base 5 rotates by ninety degrees to complete the shaping of the pins to bend the pins of the electronic component into a C shape. The support I1 moves upward. At this time, the pins of the electronic component leave the bent-angle base 5. The support I1 moves downward, and the fixture 8 loosens. It should be noted that in order to prevent the already shaped pins of the electronic component from returning to the bent-angle base 5 when the support I1 moves downward, the bent-angle base 5 can be adjusted by a certain angle to avoid the above situation. The electronic component returns to the conveyor belt and continues to move along the conveyor belt to the discharging end. Then, the fixture 8 rotates and resets, and the support I1 moves upward and resets, repeating the above process.

[0035] In this embodiment, the size of the accommodation space for the electronic component is changed by moving the support I1, so as to meet the placement requirements of electronic components with different thicknesses and make it have better versatility. It should be noted that in actual use, in this embodiment, since the position adjustment of the support I1 and the position adjustment of the support II3 are not carried out simultaneously, the linear motor module 10 for controlling the support I1 and the linear motor module 10 for controlling the support II3 do not run synchronously.

[0036] To sum up, this embodiment has the following advantages: It can clamp a batch of horizontal-pin components, can cut the pins without additional disassembly, and can shape the component pins into a C shape to better meet the requirements for the shape of electronic components on the circuit board.

[0037] For the naming of each component involved, the function described in the specification is used as the naming standard, and is not limited by the specific nouns used in this utility model. Those skilled in the art can also choose other nouns to describe the names of the various components of this utility model.
