[0071] In some preferred embodiments of the present application, the number of driving wheels 21 is two, and the two driving wheels 21 are oppositely arranged.

[0072] Specifically, Figure 1 、 Figure 2 and Figure 3 As shown in FIG. 1, the feeding mechanism 3 comprises a feeding conveyor 31, a first cylinder 32 and a second cylinder 33, the feeding conveyor 31 is used to convey the capacitors to a first preset position, the first cylinder 32 and the second cylinder 33 are used to push the capacitors at the first preset position to the clamping mechanism 4.

Figure 4 Further, as shown in FIG. 3, the feeding mechanism 3 further comprises a first cam linkage mechanism 35 connected with the third cylinder 34, the first cam linkage mechanism 35 is used to drive the third cylinder 34 to move closer to or away from the rack 1 in the vertical direction, so as to prevent the third cylinder 34 from interfering with the clamping mechanism 4 and affecting the movement of the clamping mechanism 4.

[0075] Figure 4 Specifically, as shown in FIG. 4, the first cam linkage mechanism 35 is connected with a first connecting plate 354, and the third cylinder 34 is connected with a second connecting plate 342, the first cam linkage mechanism 35 is connected with the third cylinder 34 through the first connecting plate 354 and the second connecting plate 342, so as to realize the movement of the third cylinder 34 along the vertical direction driven by the first cam linkage mechanism 35.

Since the first cam 351 is an irregular circular structure, when the first cam 351 rotates, it will drive the first swing piece 355 to swing up and down, thereby driving the first connecting rod 353 to move along the vertical direction. Figure 4 Specifically, the first cam linkage mechanism 35 comprises a first cam 351, a first ball bearing 352, a first connecting rod 353 and a first swing piece 355, the first ball bearing 352 is installed in the first swing piece 355, the first cam 351 is connected with the first connecting rod 353 through the first swing piece 355, the first cam 351 is an irregular circular structure, and the first connecting rod 353 is vertically arranged. Since the first cam 351 is an irregular circular structure, when the first cam 351 rotates, it will drive the first swing piece 355 to swing up and down, thereby driving the first connecting rod 353 to move along the vertical direction.

[0077] ​​

[0078] Further, the first cam link mechanism 35 further comprises at least one first support rod 356, the first support rod 356 is vertically arranged, and the first cam link mechanism 35 is connected with the rack 1 through the first support rod 356.

[0079] Specifically, the first cam link mechanism 35 is detachably connected with the first support rod 356 through the first connecting plate 354, one end of the first support rod 356 is connected with the first connecting plate 354, and the other end is connected with the rack 1.

[0080] Further, Figure 5 The overall structure of the clamping mechanism 4 in the present application is shown in the figure, Figure 5 As shown in the figure, the clamping mechanism 4 comprises a third connecting plate 41, a pushing shaft 43, a blocking rod 44, a supporting block 45 and a clamping part. Among them, the clamping mechanism 4 is connected with the chain 22 through the third connecting plate 41, so as to realize the synchronous rotation of the clamping mechanism 4 with the chain 22; the pushing shaft 43 is located on the side of the clamping mechanism 4 facing the third air cylinder 34, the clamping part is rotationally connected with the third connecting plate 41, the pushing shaft 43 is pushed by the third air cylinder 34 to drive the clamping part to approach the blocking rod 44, the blocking rod 44 cooperates with the clamping part, so as to realize the clamping of the clamping part on the capacitor; the supporting block 45 is connected to the end of the blocking rod 44 away from the pushing shaft 43, and the supporting block 45 is used to lift the capacitor from below, so as to prevent the capacitor from falling off in the vertical direction.

[0081] Further, the clamping part comprises an L-shaped claw 421, two connecting strips 422, a pushing block 423, a first elastic body 427, and a first connecting shaft 424, a second connecting shaft 425 and a third connecting shaft 426 corresponding to the connecting strips 422, wherein one side of the L-shaped claw 421 abuts against the capacitor, and the other side is rotationally connected with the connecting strips 422 through the third connecting shaft 426; the pushing block 423 is vertically arranged with the pushing shaft 43 and is connected to the end of the blocking rod 44 away from the L-shaped claw 421, and the pushing block 423 is rotationally connected with the connecting strips 422 through the first connecting shaft 424; the middle part of the connecting strips 422 is rotationally connected with the third connecting plate 41 through the second connecting shaft 425; one end of the first elastic body 427 is connected to the third connecting shaft 426 corresponding to one of the connecting strips 422, and the other end is connected to the first connecting shaft 424 corresponding to the other connecting strip 422, so that the first elastic body 427 has intersection points with the extensions of the two connecting strips 422.

[0082] Further, as shown in the figure, Figure 4 The movement direction of the third air cylinder 34 is horizontal, and the first driving claw 341 is arranged on the third air cylinder 34, when the third air cylinder 34 moves in the horizontal direction, the first driving claw 341 can approach or move away from the pushing shaft 43, so as to drive the connecting strips 422 to rotate around the second connecting shaft 425.

[0083] In summary, the third cylinder 34 pushes the push shaft 43 horizontally via the first drive claw 341. Since one end of the push block 423 and the connecting bar 422 is rotatably connected to the push block 423 via the first connecting shaft 424, and the other end is rotatably connected to the L-shaped claw 421 via the third connecting shaft 426, and the middle is rotatably connected to the third connecting plate 41 via the second connecting shaft 425, when the third cylinder 34 pushes the push shaft 43 towards the stop lever 44, the L-shaped claw 421 moves away from the stop lever 44. As the distance between the L-shaped claw 421 and the stop bar 44 increases, the length of the first elastic body 427 increases. At this time, the second cylinder 33 pushes the capacitor onto the support block 45. The third cylinder 34 moves away from the stop bar 44. At this time, the first drive claw 341 moves away from the push shaft 43. Under the action of the first elastic body 427, the first elastic body 427 pulls the L-shaped claw 421 to move closer to the stop bar 44, thereby reducing the distance between the L-shaped claw 421 and the stop bar 44, thus achieving the effect of clamping the capacitor.

The support part 4222 and the two first limiting strips 4221 form a space for limiting push block 423 and L-shaped claw 421. The two first limiting strips 4221 can limit the upper and lower ends of push block 423 and L-shaped claw 421, thereby realizing a stable connection between the connecting strip 422 and push block 423 and L-shaped claw 421.

[0085] In some preferred embodiments of this application, the support portion 4222 is connected to the middle position of the two first limiting bars 4221 and is respectively arranged perpendicular to the two first limiting bars 4221.

[0086] In some preferred embodiments of this application, such as Figure 5 As shown, the clamping mechanism 4 also includes a first mating part 46, which is located between the stop bar 44 and the L-shaped claw 421 and is connected to the stop bar 44.

[0089] Further, the first driving part comprises a first transmission arm 561 and a first driving arm 562. The second link 514 can drive the first transmission arm 561 to swing in the circumferential direction, thereby driving the first driving arm 562 to move along the horizontal direction.

[0092] In some preferred embodiments of the present application, the second transmission arm 5612 and the third transmission arm 5613 are fixedly connected to the two ends of the fourth connecting shaft 5611 along the axial direction thereof.

[0115] Specifically, the second limiting part 5200 is a convex structure, comprising a fourth cooperating part 5201 and a third protruding part 5202, the third protruding part 5202 is convexly arranged on the surface of the fourth cooperating part 5201 and is arranged towards the rack 1, the side edge of the pin can abut against the side edge of the third protruding part 5202, and the end of the pin can abut against the fourth cooperating part 5201, thereby realizing the limitation of the position of the pin.

[0118] Further, Figure 12 The overall structure of the detection mechanism 6 in the present application is shown in the figure. Figure 12 As shown in the figure, the detection mechanism 6 includes at least one third cam link mechanism 61, at least one detection part, and a second driving part corresponding to the detection part. The third cam link mechanism 61 drives the detection part to loosen or clamp the pins of the capacitor through the second driving part, thereby realizing the detection of the capacitor.

[0119] Specifically, the third cam link mechanism 61 includes a third cam 611, a third swing part 612, a third ball bearing 613, and a third connecting rod 614. The third ball bearing 613 is installed in the third swing part 612. The third cam 611 is connected with the third connecting rod 614 through the third swing part 612. The third cam 611 is an irregular circular structure. The third connecting rod 614 is vertically arranged. Since the third cam 611 is an irregular circular structure, when the third cam 611 rotates, it will drive the third swing part 612 to swing up and down, thereby driving the third connecting rod 614 to move in the vertical direction.

[0120] Further, the second driving part includes a fourth transmission arm 631 and a second driving arm 632. The third connecting rod 614 can drive the fourth transmission arm 631 to swing in the circumferential direction, thereby driving the second driving arm 632 to move in the vertical direction.

[0121] Specifically, one end of the fourth transmission arm 631 is rotationally connected with the third connecting rod 614, and the other end is rotationally connected with the second driving arm 632.

[0122] Further, the fourth transmission arm 631 includes a fifth connecting shaft 6311, a fifth transmission arm 6312, and a sixth transmission arm 6313. The fifth transmission arm 6312 and the sixth transmission arm 6313 are fixedly connected to the side edges of the fifth connecting shaft 6311 and are arranged in different planes in parallel. The fifth transmission arm 6312 is rotationally connected with the third connecting rod 614, and the sixth transmission arm 6313 is rotationally connected with the second driving arm 632. When the third connecting rod 614 moves up and down, it can drive the fifth transmission arm 6312 and the sixth transmission arm 6313 to rotate around the fifth connecting shaft 6311, thereby enabling the sixth transmission arm 6313 to drive the second driving arm 632 to move in the vertical direction.

[0123] In some preferred embodiments of this application, the fifth transmission arm 6312 and the sixth transmission arm 6313 are fixedly connected to both ends of the fifth connecting shaft 6311 along its axial direction.

[0124] Furthermore, in order to connect the detection mechanism 6 with the frame 1, the detection mechanism 6 also includes an eighth connecting plate 64 corresponding to the third cam linkage mechanism 61. The fifth connecting shaft 6311 is detachably connected to the eighth connecting plate 64, and the eighth connecting plate 64 is detachably connected to the frame 1.

[0125] Furthermore, each detection unit includes two guide slots 621 and at least one clamping part 622. The guide slots 621 are connected to the second drive arm 632. The second drive arm 632 can drive the guide slots 621 to move vertically relative to the clamping part 622, thereby causing one end of the clamping part 622 to loosen or clamp the lead of the capacitor, thus completing the detection of the capacitor.

[0126] Specifically, the guide groove 621 is an isosceles trapezoidal structure, with an isosceles trapezoidal cavity inside for one end of the clamping part 622 to move. Each clamping part 622 includes two clamping claws. Since the upper base and the waist of the guide groove 621 form an obtuse angle, as one end of the clamping claw moves from the waist to the upper base, that end of the clamping claw will gradually move closer, thereby causing the other end of the clamping claw to gradually move away from and release the capacitor pin; conversely, it will clamp the capacitor pin.

[0127] Furthermore, Figure 13 It shows Figure 12 A magnified view of a portion of region A in the middle, as shown below. Figure 13 As shown, in order to achieve a stable connection between the clamping part 622 and the frame 1, the detection part also includes a ninth connecting plate 623 and a tenth connecting plate 624 corresponding to the clamping claws. The clamping claws are hinged to the tenth connecting plate 624, and the clamping claws can rotate around the hinge axis. The clamping claws are connected to the ninth connecting plate 623 through the tenth connecting plate 624, and the tenth connecting plate 624 is connected to the frame 1.

[0128] Furthermore, to enable capacitor detection, two gripping claws are used to clamp the positive and negative terminals of the capacitor, respectively, and the two gripping claws are arranged alternately.

[0129] like Figure 12 As shown, in some preferred embodiments of this application, the detection mechanism 6 has two detection units and two second drive units, and the third cam linkage mechanism 61 can simultaneously detect two rows of capacitors in opposite directions during its movement.

[0130] Further, in some preferred embodiments of the present application, in order to achieve more capacitors detection at the same time, each detection part includes two third cam link mechanisms 61, the two third cam link mechanisms 61 move synchronously, and the two third cam link mechanisms 61 drive four detection parts and four second driving parts to move together.

[0131] As shown in the drawings, Figure 12 In some other preferred embodiments of the present application, the detection part includes one third cam link mechanism 61, the third cam link mechanism 61 drives the fifth connecting shaft 6311 on the corresponding eighth connecting plate 64 to rotate, and the fifth connecting shaft 6311 drives the fifth connecting shaft 6311 on the other eighth connecting plate 64 to rotate through the first transmission shaft 65, so that one third cam link mechanism 61 can drive two second driving arms 632 to move in the vertical direction.

[0132] It can be imagined that the number of detection parts can be adjusted according to the needs to meet the actual production needs.

[0133] In some preferred embodiments of the present application, the detection part can group the clamping part 622 to form different detection modules, and each detection module can realize the detection of different performances of the capacitor in turn. In actual production, the charging detection and discharge detection of the capacitor can be carried out according to the needs.

[0134] The capacitors detected by each different detection module of the detection mechanism 6 may have some defective capacitors, and at this time, the defective capacitors need to be sent out of the detection line through each discharging mechanism 7, and the capacitors detected by each detection module are sent out of the detection line through a separate discharging mechanism 7.

[0135] Specifically, as shown in the drawings, Figure 2 and Figure 3 The discharging mechanism 7 includes a discharging conveyor belt 71 and a fourth cylinder 72, and the fourth cylinder 72 is used to push the capacitors loosened by the clamping mechanism 4 to the discharging conveyor belt 71.

[0136] Specifically, the fourth cylinder 72 and the discharging conveyor belt 71 are arranged opposite to the two sides of the clamping mechanism 4, when the defective capacitors reach the corresponding position of the discharging conveyor belt 71, the control unit controls the clamping mechanism 4 to loosen the capacitors, and the fourth cylinder 72 pushes the capacitors to the discharging conveyor belt 71, so as to send the defective capacitors out of the detection line.

[0137] For the capacitors that pass the detection of the detection mechanism 6, when the capacitors that pass the detection reach the corresponding position of the discharging conveyor belt 71, the control unit controls the clamping mechanism 4 to loosen the capacitors, and the fourth cylinder 72 pushes the capacitors to the discharging conveyor belt 71, so as to send the capacitors that pass the detection out of the detection line.

[0138] Further, Figure 14The overall structure of the discharging mechanism 7 in the present application is shown in FIG. 1, and the discharging mechanism 7 is shown in FIG. 2. Figure 14 As shown in FIG. 2, the discharging mechanism 7 further comprises a pushing claw 73, which is installed on one side of the fourth cylinder 72 facing the discharging conveyor belt 71. The control unit controls the fourth cylinder 72 to extend or retract, so that the pushing claw 73 can extend or retract under the action of the fourth cylinder 72, and when the pushing claw 73 extends, it can push the capacitor to the discharging conveyor belt 71.

[0139] Further, in order to realize the cooperation of the discharging mechanism 7 and the clamping mechanism 4 to release the capacitor, the discharging mechanism 7 further comprises a fifth cylinder 74, which is located on the inner side of the clamping mechanism 4. The fifth cylinder 74 can push the clamping mechanism 4 to open, thereby realizing the release of the capacitor by the clamping mechanism 4.

[0140] Further, the movement direction of the fifth cylinder 74 is horizontal, and the fifth cylinder 74 is provided with a second driving claw 741. When the fifth cylinder 74 moves in the horizontal direction, the second driving claw 741 can approach or move away from the pushing shaft 43.

[0141] Further, as shown in FIG. 2, the discharging mechanism 7 further comprises a fourth cam linkage mechanism 75 connected with the fifth cylinder 74, which is used to drive the fifth cylinder 74 to approach or move away from the rack 1 in the vertical direction, preventing the fifth cylinder 74 from interfering with the movement of the clamping mechanism 4. Figure 14

[0142] Specifically, the fourth cam linkage mechanism 75 is connected with an eleventh connecting plate 755, and the fifth cylinder 74 is connected with a twelfth connecting plate 756. The fourth cam linkage mechanism 75 and the fifth cylinder 74 are connected through the eleventh connecting plate 755 and the twelfth connecting plate 756, so that the fourth cam linkage mechanism 75 can drive the fifth cylinder 74 to move in the vertical direction.

[0143] Further, the fourth cylinder 72 is connected to the twelfth connecting plate 756.

[0144] Further, the fourth cam linkage mechanism 75 comprises a fourth cam 751, a fourth ball bearing 752, a fourth connecting rod 753 and a fourth swing piece 754. The fourth ball bearing 752 is installed in the fourth swing piece 754, and the fourth cam 751 is connected with the fourth connecting rod 753 through the fourth swing piece 754. The fourth cam 751 is an irregular circular structure, and the fourth connecting rod 753 is vertically arranged. Since the fourth cam 751 is an irregular circular structure, when the fourth cam 751 rotates, it will drive the fourth swing piece 754 to swing up and down, thereby driving the fourth connecting rod 753 to move in the vertical direction.

[0145] ​Further, the fourth cam link mechanism 75 further comprises at least one third supporting rod 757, the third supporting rod 757 is arranged to connect the fourth cam link mechanism 75 with the rack 1.

[0146] Specifically, the fourth cam link mechanism 75 is detachably connected with the third supporting rod 757 through an eleventh connecting plate 755, one end of the third supporting rod 757 is connected with the eleventh connecting plate 755, and the other end is connected with the rack 1.

[0147] Since the existing automatic detection and sorting machine for capacitors needs to be driven by a separate motor to complete the work flow in sequence, there are problems of complex system structure, low efficiency, high manufacturing cost and high control difficulty, and also increases the fault points in the use process of the equipment. In the present application, one motor can realize the cooperation of each mechanism of the automatic detection and sorting machine for capacitors.

[0148] Specifically, Figure 15 The overall structure diagram of the driving unit and the first cam 351, the second cam 511, the third cam 611 and the fourth cam 751 in the present application is shown.
