[0029] See also Figure 1-7 As shown, a transformer pin trimming device of the present invention comprises a feed track 1 for conveying transformers, one side of the feed track 1 is provided with a translation assembly 2 perpendicular to the forward direction of the feed track 1, the translation assembly 2 is provided with at least one pedicure scissors 3, and a clearance gap 4 is provided on the feed track 1 opposite to the pedicure scissors 3. The feed track is connected to an external vibrating plate and other feeding equipment, a straight vibrator is provided under the feed track for vibrating the feed track for conveying, and the feed track opposite to the pedicure scissors is split-connected with the feed track with vibration at the front end to avoid vibration affecting the pin trimming process. According to production needs, multiple pedicure scissors can be set to further improve the trimming efficiency.

[0030] A positioning stopper assembly 5 is provided on the feed track 1 on the side of the clearance gap 4 close to the incoming material direction; a loading assembly 6 for moving the transformer to the clearance gap 4 is provided on one side of the feed track 1. The loading assembly moves the transformer to be trimmed on the feed track to the clearance gap for automatic trimming by the trimming scissors. This process is automated, which effectively improves efficiency, greatly reduces labor costs, and can work stably for a long time. In actual production, it is found that this trimming method can improve work efficiency by at least 20% compared to manual trimming within the same working time, and the equipment does not need to rest in the middle, can work continuously for a long time, and the daily output has increased by at least 40%.

[0031] The entire trimming process will not be affected by the workers' proficiency and working status, and is not prone to problems such as wrong cutting and insufficient cutting. It can ensure the accuracy of transformer pin trimming and ensure that the trimming of each transformer is uniform.

[0032] The subsequent transformer is blocked by the positioning blocking component to ensure that the transformer corresponds to the pedicure scissors one-to-one when the feet are trimmed, and to ensure that the transformer transported on the subsequent feeding track will not affect the trimming feet.

[0033] In this embodiment, preferably, the positioning and blocking assembly 5 comprises an installation slot 5a provided on the feeding track 1, and a vertical block 5b is hinged in one end of the installation slot 5a close to the material incoming direction; a rotating unit 7 connected to the lower end of the vertical block 5b is provided at the bottom of the feeding track 1. When loading, the vertical block is driven by the rotating unit to rotate toward the installation slot to make way for the transformer to pass through. Compared with the structure of inserting the block from the side to block the material, it can prevent the block from being blocked by the next transformer and unable to reset, and when the vertical block is reset, the next transformer can be pushed back to the front to prevent its position deviation from affecting the next loading.

[0034] The rotating unit can adopt common driving methods such as cylinders and motors, and can be rotated in time to make way and reset when the transformer passes.

[0035] Further preferably, the rotating unit 7 includes a mounting column 7a arranged on the bottom of the feed track 1 on one side of the mounting long hole 5a along the length direction, and a reset spring 7b is connected between the mounting column 7a and the bottom of the vertical block 5b; in the initial state, the vertical block 5b is supported by the reset spring 7b to maintain a vertical state. After adopting the above structure, when the transformer moves forward, it will push down the vertical block to automatically give way, and then automatically reset by the reset spring, which can complete the reset more promptly and quickly than using a cylinder or other equipment for external drive.

[0036] In this embodiment, the feeding assembly 6 includes a lifting platform 6a arranged on one side of the feeding track 1, a horizontal guide rail 6b parallel to the feeding track 1 and in the same forward direction is provided on the lifting platform 6a, a sliding suspension 6c is provided on the horizontal guide rail 6b, a horizontal cylinder 6d cooperating with the sliding suspension 6c is provided at one end of the horizontal guide rail 6b, and a positioning plug 6e cooperating with the through hole of the transformer skeleton is provided at the free end of the sliding suspension 6c; a stripping assembly 8 cooperating with the positioning plug 6e for stripping is provided on the feeding track 1 at the clearance gap 4. When the pedicure scissors trim the pins of the transformer, the positioning plug can fix the transformer to prevent the transformer from deviating from the position. The transformer stripped by the stripping assembly will remain on the feeding track and be pushed out when the next feeding is carried out.

[0037] In this embodiment, preferably, the stripping assembly 8 includes a gantry 8a disposed on the feeding track 1, and a long notch 8b adapted to the positioning plug 6e is provided at one end of the gantry 8a close to the incoming material direction; when the lifting platform 6a is raised, the transformer is blocked by the gantry 8a and separated from the positioning plug 6e. The height of the gantry is 0.5-1.5mm greater than the height of the transformer, which can ensure that the transformer can be smoothly transported under the gantry and avoid friction between the upper end of the transformer and the gantry, and when the lifting platform raises the positioning plug for stripping, it can prevent the transformer from being separated from the feeding track and affecting subsequent transportation.

[0038] In this embodiment, preferably, at least two pedicure scissors 3 are provided on the translation assembly 2, and sliding suspensions 6c corresponding to each pedicure scissors 3 are provided on the horizontal guide rail 6b, and positioning plugs 6e are provided on each sliding suspension 6c; infrared sensors 9 cooperating with the transformers to be trimmed are provided on the feeding track 1 on the side of the positioning and blocking assembly 5 close to the incoming material direction, and the number of the infrared sensors 9 corresponds to the number of the pedicure scissors 3. In this embodiment, three pedicure scissors are set to trim at the same time, further improving the trimming efficiency of the transformer, and can improve the work efficiency by at least twice compared with manual trimming within the same working time, so that the daily output is doubled.

[0039] In the initial state, the positioning block is located above the feed track at the infrared sensor and corresponds to the infrared sensor one by one. When the three infrared sensors all sense the transformer to be trimmed, the lifting platform will descend to make the positioning block cooperate with the transformer to be trimmed, avoiding the positioning block from being empty-loaded and ensuring that each pedicure scissors can complete the trimming work.

[0040] The piston rod of the horizontal cylinder 6d is connected to the farthest sliding suspension 6c; a linkage distance component 10 is provided between two adjacent sliding suspensions 6c. In the initial state, the distance between two adjacent positioning blocks 6e is equal to the distance between two adjacent through holes of the transformer to be trimmed; when the sliding suspension 6c moves to the position corresponding to the clearance gap 4, the distance between two adjacent positioning blocks 6e is the same as the distance between two pedicure scissors 3. In this embodiment, the linkage distance component drives the three sliding suspensions to move synchronously and enables the positioning blocks on the sliding suspension to accurately match the transformer to be trimmed.

[0041] Further preferably, the linkage distance assembly 10 includes a through hole 10a provided on the sliding suspension 6c on the side away from the horizontal cylinder 6d, a linkage rod 10b matching the through hole 10a is provided on the sliding suspension 6c on the side close to the horizontal cylinder 6d, and a limit nut 10c is provided at the front section of the linkage rod 10b. The linkage rod is detachably mounted on the sliding suspension through the nut, and when the number of sliding suspensions is three or more, a clearance through hole is provided on the sliding suspension located at the rear to prevent the nut at the mounting end of the linkage rod on the front sliding suspension from colliding with the rear sliding suspension when returning to the initial state.

[0042] When the sliding suspension 6c located on the side away from the horizontal cylinder 6d moves forward to the front end face and cooperates with the limiting nut 10c, the rear sliding suspension 6c is dragged forward by the linkage rod 10b and the distance between two adjacent positioning blocks 6e is the same as the distance between the two pedicure scissors 3.

[0043] A limiting column 10d is provided on each sliding suspension 6c. In the initial state, the limiting column 10d on the sliding suspension 6c contacts the adjacent sliding suspension 6c, and the distance between two adjacent positioning blocks 6e is equal to the distance between two adjacent transformer through holes to be trimmed.

[0044] In this embodiment, the center of the feed track 1 behind the positioning stopper assembly 5 is detachably provided with a first positioning strip 11 matched with the transformer, and the width of the first positioning strip 11 is adapted to the pin width of the transformer to be trimmed; an introduction portion 12 is formed by chamfering at one end of the first positioning strip 11 near the positioning stopper assembly 5, and introduction blocks 13 are provided on the feed track 1 on both sides of the introduction portion 12, and the front ends of the two introduction blocks 13 cooperate to form an introduction bell mouth. During the trimming process, the transformer is limited by the first positioning strip to ensure that the transformer pin can accurately cooperate with the front trimming portion of the pedicure scissors when it is in the gap.

[0045] When the loading assembly feeds the transformer onto the first positioning strip, it is guided by the introduction bell mouth formed by the introduction part and the introduction blocks on both sides to avoid collision between the transformer and the end of the first positioning strip, thereby ensuring that the transformer pins match the first positioning strip.

[0046] In this embodiment, the center of the feeding track 1 on the side of the positioning stopper assembly 5 close to the incoming material direction is detachably provided with a second positioning strip 14 that matches the transformer, and the width of the second positioning strip 14 is adapted to the pin width of the transformer to be sheared. During the feeding process, the transformer is limited by the second positioning strip to prevent the transformer from shifting during the vibration conveying process, thereby ensuring that the transformer can accurately match the feeding assembly.

[0047] In addition, the second positioning strip is in contact with the bottom surface of the transformer, and in this embodiment, it can provide support when the positioning plug is pressed down and inserted into the through hole of the transformer, thereby avoiding deformation of the transformer pins due to the downward pressure.

[0048] During operation, the transformer to be trimmed is transported to the vertical block through the feed track. When multiple infrared sensors sense the transformer, the lifting platform descends to insert the positioning plug located above into the through hole of the transformer frame. The horizontal cylinder piston rod extends out to push the sliding suspension to move the transformer to the clearance gap. The translation assembly pushes the trimming scissors into the clearance gap to cooperate with the pins of the transformer to be cut for trimming.

[0049] After the trimming is completed, the lifting platform rises, the transformer is blocked by the gantry and disengaged from the positioning block, and the positioning block returns to the initial position for the next transportation.
