[0050] A clamping block 73 is fixed to the bottom wall of the connecting plate 72, and a sliding plate 74 is fixed to the top wall of the connecting plate 72;

[0051] The sliding plate 74 is slidably installed on the first guide rail 75.

[0052] In this embodiment, the clamping assembly 7 is used to clamp and fix the SMD to be trimmed, preventing the SMD from shifting during the trimming process. When the clamping assembly 7 works, the electric push rod 71 is controlled to extend, and the electric push rod 71 controls the clamping block 73 to move downward until the clamping block 73 fixes the SMD on the feeding assembly 10.

[0053] The lifting assembly 8 includes a C-shaped frame 81, which is fixed on the front wall of the mounting block 5. A screw rod 82 is rotatably installed between the upper and lower walls of the C-shaped frame 81;

On the one hand, it enables the pins of the SMD to smoothly enter the trimming assembly 9, and on the other hand, it enables the SMD after trimming to be smoothly taken out. When the lifting assembly 8 is used, the servo motor 85 drives the screw rod 82 to rotate, and during the rotation of the screw rod 82, the first slider 83 is driven to move up and down, thereby driving the trimming assembly 9 to move up and down.

[0057] The defective pin component 9 includes a connecting block 91, the connecting block 91 is fixed on the front wall of the first slider 83, one side of the top wall of the connecting block 91 is fixed with an adjusting block 92, and the other end of the top wall of the connecting block 91 is movably installed with a lower clamping block 93;

[0058] One side of the lower clamping block 93 is fixed with a connecting rod 97, the top wall of the lower clamping block 93 is symmetrically fixed with guide shafts 96, and a cylinder 94 is installed above the lower clamping block 93;

[0061] A limiting block 98 is fixed on the rod body of the connecting rod 97, and a threaded cap 99 is screwed on the end of the connecting rod 97 away from the lower clamping block 93.

[0062] The adjusting block 92 is fixed on the connecting block 91 by bolts, a plurality of groups of threaded holes matched with the bolts are opened on the top wall of the connecting block 91, and a groove is opened on the top wall of the adjusting block 92 corresponding to the position of the connecting rod 97.

[0063] In this embodiment, the defective pin component 9 is used for performing defective pin operations on SMDs, and at the same time, it can perform defective pin operations on SMDs of different models, with a wide range of applications. When the defective pin component 9 performs defective pin operations, the cylinder 94 contracts, causing the upper clamping block 95 to move downward, and cooperating with the lower clamping block 93 to perform defective pin operations on the SMD. When it is necessary to perform defective pin operations on SMDs of different models, by moving the adjusting block 9, the distance between the two defective pin components 9 is changed, so as to achieve defective pin operations on SMDs of different models. Since a plurality of groups of threaded holes matched with the bolts are opened on the top wall of the connecting block 91, the adjusting block 9 can adjust its position according to actual needs, and then adjust the positions of the upper clamping block 95 and the lower clamping block 93. At the same time, the threaded cap 99 cooperates with the connecting rod 97 and the limiting block 98, which can facilitate the disassembly and installation of the lower clamping block 93, and can facilitate replacement when the defective pin component 9 is damaged.

[0064] The feeding component 10 includes a second guide rail 101, the second guide rail 101 is fixed on the top wall of the mounting plate 3, and a second slider 102 is slidably installed on the second guide rail 101;

[0065] The top wall of the second slider 102 is fixed with a cross plate 103;

[0066] The top wall of the cross plate 103 is fixed with a placement table 104, and a hydraulic rod 107 is installed on one side of the cross plate 103;

[0067] The hydraulic rod 107 is fixed on the top wall of the mounting plate 3 through a fixing block 106, and the movable end of the hydraulic rod 107 is fixedly connected to one side of the cross plate 103;

[0068] The top wall of the placement table 104 is provided with a placement groove 105.

[0070] In this embodiment, the feeding assembly 10 is used to move the SMD to the position of the pin aligning assembly 9 for pin aligning operation. The placement groove 105 provided on the placement table 104 is used to place the SMD to be pin aligned, and the provided hydraulic rod 107 is used to control the movement of the SMD to the position of the pin aligning assembly 9. At the same time, the provided placement table 104 is fixed by bolts. Therefore, when pin aligning operations need to be performed on different models of SMDs, the placement table 104 can be directly removed and replaced.

[0071] At the same time, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0072] Working principle: In the initial state, the hydraulic rod 107 is in the extended state. At this time, the SMD is placed in the placement groove 105, and the hydraulic rod 107 is controlled to contract until the placement table 104 is directly below the clamping block 73. At this time, the pins of the SMD are located between the upper clamping block 95 and the lower clamping block 93. The electric push rod 71 is controlled to extend, and the electric push rod 71 controls the clamping block 73 to move downward until the clamping block 73 abuts the SMD in the placement groove 105. Then, the air cylinder 94 is controlled to contract, so that the upper clamping block 95 moves downward to cooperate with the lower clamping block 93 to perform pin aligning operation on the SMD. After pin aligning is completed, the air cylinder 94 extends, the upper clamping block 95 is separated from the lower clamping block 93, and at the same time, the pin aligning assembly 9 is controlled to move downward a certain distance through the lifting assembly 8, so that the lower clamping block 93 is separated from the SMD. The hydraulic rod 107 is controlled to extend to push the pin aligned SMD forward, facilitating the removal of the SMD.
