Unless otherwise specified, the terms used herein have the meanings commonly used in the art. The same reference signs in the drawings represent the same components.

[0029] The middle of the left side wall of the flattening platform 1 is provided with a U-shaped guide arc groove 101, the middle of the right side wall of the flattening platform 1 is provided with a support roller shaft 102 at equal distances, and the front and rear ends of the right side wall of the flattening platform 1 are rotationally connected with drive roller shafts 103. The drive roller shafts 103 are connected to the inner sides of the front and rear ends of the capacitor conveying belt 2. Therefore, the support roller shaft 102 can uniformly support the middle part of the capacitor conveying belt 2, so as to avoid the deformation of the conveying belt due to the weight of the capacitor. Meanwhile, the drive roller shafts 103 can drive the capacitor conveying belt 2 to realize uniform transmission, so as to ensure that the aluminum capacitor and the pin can be stably conveyed to the flattening station, and prevent the pin from being misaligned due to the deviation of the conveying belt during the conveying process.

[0030] The right side of the outer side wall of the capacitor conveying belt 2 is provided with an arc-shaped placement groove 201 at equal distances. The left side of the outer side wall of the placement groove 201 is provided with a positioning protrusion 202 at equal distances. The top of the right side wall of the positioning protrusion 202 is fixedly connected with a magnetic suction piece 203. The front and rear sides of the positioning protrusion 202 are symmetrically provided with U-shaped pin clamping grooves 204. Therefore, the placement groove 201 can be matched with the shape of the aluminum capacitor body, so as to realize the preliminary positioning of the capacitor body. The pin clamping groove 204 can accurately clamp the pin of the aluminum capacitor, so as to avoid the shaking of the pin during the conveying process.

The front and rear ends of the drive screw 301 are rotationally connected to the front and rear side walls of the guide arc groove 101 formed in the left side wall of the flattening platform 1. Therefore, the driving motor 3 can drive the drive screw 301 to realize the forward and reverse rotation. The rotation of the motor is converted into the sliding motion of the moving arc block 401 along the guide arc groove 101 through the cooperation between the drive screw 301 and the moving arc block 401. Then, the moving carriage 4 is driven to realize the arc trajectory adjustment, so that the flattening block 6 can adjust the working position according to the pin flattening requirement, adapt to the flattening position requirement of the pins of aluminum capacitors of different specifications, and improve the adaptive flexibility of the device.

[0033] The bottom of the right side wall of the moving slide 4 is fixedly installed with a moving arc block 401, the moving arc block 401 is slidingly connected in the guide arc groove 101 opened in the left side wall of the flattening platform 1, the moving arc block 401 is screwedly connected to the driving screw 301 of the driving motor 3, a vertical U-shaped guide sliding groove 402 is opened in the middle of the right side wall of the moving slide 4, the middle of the upper and lower end faces of the guide sliding groove 402 is fixedly installed with a balance bar 403, a mounting top plate 404 is fixedly installed on the top of the right side wall of the moving slide 4, and the middle of the top of the mounting top plate 404 is fixedly installed with the hydraulic cylinder 5, therefore, the sliding cooperation of the moving arc block 401 and the guide arc groove 101 can ensure the track stability of the moving slide 4 during adjustment, avoiding jamming or deviation, the guide sliding groove 402 and the balance bar 403 can guide and constrain the vertical movement of the flattening block 6, preventing the flattening block 6 from shaking due to uneven stress under the driving of the hydraulic cylinder 5, and the mounting top plate 404 can provide stable mounting support for the hydraulic cylinder 5, ensuring that the driving force of the hydraulic cylinder 5 can be vertically transmitted to the flattening block 6, improving the stability and accuracy of the flattening pressure.

[0034] By adopting the above technical scheme, flexible adjustment of the moving slide 4 can be realized through cooperation of the driving motor 3 and the driving screw 301, so that the flattening block 6 can adapt to the flattening position requirements of pins of different specifications, and meanwhile, the guide sliding groove 402, the balance bar 403 and the mounting top plate 404 of the moving slide 4 provide stable support and guidance for installation of the hydraulic cylinder 5 and movement of the flattening block 6, ensuring that the flattening pressure can be accurately and stably transmitted to the pin, which not only improves the flexibility of the device in adapting to pins of different specifications, but also guarantees the accuracy and stability of the flattening pressure, reducing the problem of poor flattening caused by position deviation or uneven pressure.

[0036] The two balance side plates 701 are symmetrically provided on the front and back of the auxiliary pressing block 7, the opposite side walls of the two balance side plates 701 are symmetrically provided with trapezoidal guide sliding grooves 702, the guide sliding grooves 702 are slidably connected to the guide sliding blocks 602 of the flattening block 6, the top of the auxiliary pressing block 7 is symmetrically provided with two sliding rods 703, the top of the sliding rod 703 is slidably connected to the sliding hole of the front supporting plate 601 of the flattening block 6, the top of the sliding rod 703 is provided with a limiting block 704, the limiting block 704 is located on the top side of the top end face of the flattening block 6, the outer side of the sliding rod 703 on the upper side of the auxiliary pressing block 7 is sleeved with a supporting spring 705, the bottom of the auxiliary pressing block 7 is equidistantly provided with a plurality of alignment grooves 706, the alignment grooves 706 correspond to the alignment protrusions 202 on the outer side of the capacitor conveying belt 2, three “U”-shaped pressing block grooves 707 are provided between adjacent alignment grooves 706, therefore, the limiting block 704 can prevent the auxiliary pressing block 7 from excessively sliding downward and separating from the flattening block 6 under the elastic force of the supporting spring 705, ensuring the safety of the cooperative movement of the auxiliary pressing block 7 and the flattening block 6, the elastic buffering effect of the supporting spring 705 can avoid the instantaneous impact force when the hydraulic cylinder 5 is pressed downward from being directly transmitted to the pin, reducing the risk of pin breakage caused by brittle deformation, the three “U”-shaped pressing block grooves 707 can adapt to aluminum capacitors of multiple pin specifications, and the “U”-shaped structure can wrap the side edges of the pin to prevent the pin from deviating to both sides during the flattening process, cooperating with the positioning of the alignment grooves 706 and the alignment protrusions 202, the coherent operation of “pre-positioning-elastic pressing-precise shaping” is realized, further improving the consistency and qualification rate of pin flattening of different specifications.

[0037] By adopting the above technical scheme, the stability and flatness of the vertical movement of the flattening block 6 can be ensured through the double sliding guide structure of the flattening block 6, cooperating with the elastic buffering, precise positioning and multi-pin adaptation design of the auxiliary pressing block 7, realizing “pre-positioning-elastic pressing-precise shaping” during the pin flattening process, avoiding damage to the pin caused by instantaneous impact force, preventing pin deviation, adapting to multiple specifications of pins, significantly improving the surface flatness, consistency and qualification rate after pin flattening, prolonging the service life of the flattening block 6, and ensuring the operation safety and device adaptability.
