[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0030] like Figures 1 to 4 As shown, an embodiment of this utility model provides an automatic capacitor packing device, which mainly includes a transmission channel 300, a placement platform 400, a pushing and swinging mechanism, and a packing platform 500.

[0031] The end of the transmission channel 300 engages with the placement platform 400 to move the capacitor 100 to one side of the placement platform 400. The capacitor 100 is transported in the transmission channel 300 with its casing 110 facing down and its leads 120 facing up. When the capacitor 100 is transferred to the placement platform 400, it is also arranged with its casing 110 facing down and its leads 120 facing up, facilitating the transfer and packaging of the capacitor 100. The transmission direction of the transmission channel 300 is parallel to the first side 401 of the placement platform 400, and the transmission channel 300 is adjacent to the first side 401, facilitating the movement of multiple capacitors 100 in a row from the transmission channel 300 onto the placement platform 400.

[0032] The packing table 500 is located on one side of the placement table 400 and is used to place the packaging box 200 with a side opening 210 facing the placement table 400. The push-swing mechanism is used to arrange the capacitors 100 on the transmission channel 300 onto the placement table 400 and move the capacitors 100 on the placement table 400 from the side opening 210 of the packaging box 200 into the packaging box 200, thereby realizing the automatic packing of the capacitors 100.

[0033] The pushing and swinging mechanism includes a first pushing mechanism 430, a first blocking mechanism 440, and a second pushing mechanism 450.

[0034] The first pushing mechanism 430 and the first blocking mechanism 440 are arranged opposite each other in a first direction, which is perpendicular to the conveying direction of the transmission channel 300. The first pushing mechanism 430 includes a first pushing plate 431, which extends along the conveying direction of the transmission channel 300. That is, the first pushing plate 431 has a certain length along the conveying direction of the transmission channel 300. This length can be greater than, equal to, or slightly less than the total length of the multiple capacitors 100, so as to facilitate the simultaneous pushing of a row of multiple capacitors 100. The first pushing plate 431 can move along the first direction above the transmission channel 300 between the side of the transmission channel 300 away from the placement table 400 and the side of the transmission channel 300 close to the placement table 400, thereby realizing the transfer of a row of multiple capacitors 100 between the transmission channel 300 and the placement table 400. The first blocking mechanism 440 includes a first baffle 441, which extends along the conveying direction of the transmission channel 300. The first baffle 441 has a certain length along the conveying direction of the transmission channel 300, which can be greater than, equal to, or slightly less than the total length of the multiple capacitors 100, facilitating the synchronous movement of a row of multiple capacitors 100 by the first baffle 441. The length of the first baffle 441 can be equal to or comparable to the length of the first push plate 431. The first baffle 441 can move on the placement table 400 along a first direction between a third position close to the transmission channel 300 and a fourth position away from the transmission channel 300. The first baffle 441 is used to limit the capacitors 100 pushed by the first push plate 431, preventing the capacitors 100 from tipping over or becoming misaligned. As the first pushing mechanism 430 pushes the capacitors 100 row by row onto the placement table 400, the first baffle 441 gradually retreats away from the transmission channel 300. Multiple rows of capacitors 100 can be accommodated between the first baffle 441 and the first push plate 431 to form an array of capacitors 100.

[0035] The second pushing mechanism 450 and the packing table 500 are arranged opposite each other in a second direction, which is parallel to the conveying direction of the transmission channel 300. The second pushing mechanism 450 includes a second pushing plate 451, which extends along a first direction, i.e., the second pushing plate 451 has a certain length along the first direction, which is greater than or equal to or slightly less than the lateral dimension of the multiple rows of capacitors 100, so that the second pushing plate 451 can simultaneously push the multiple rows of capacitors 100. The second pushing plate 451 can move along the second direction on the placement table 400. The moving area of ​​the second pushing plate 451 at least partially overlaps with the moving area of ​​the first baffle 441. When the first baffle 441 retracts to its limit position, the second pushing plate 451 is used to push the full array of capacitors 100 to the packing table 500. Then the second pushing plate 451 retracts, and the first baffle 441 moves to a position close to the transmission channel 300 to facilitate the array arrangement of the next array of capacitors 100.

[0036] The packing table 500 is adjacent to the second side 402 of the placement table 400, and the second side 402 is adjacent to the first side 401. The packing table 500 is used to place the packaging box 200 having a side opening 210 facing the placement table 400. The capacitor 100 pushed by the second pusher plate 451 enters the packing table 500 through the side opening 210 via the second side 402 of the placement table 400.

[0037] In some examples, the first pusher mechanism 430 also includes a second drive member 432, which may be, for example, a cylinder. The second drive member 432 is connected to the transfer channel 300 or the placement table 400. The second drive member 432 is connected to the first pusher plate 431 and is used to drive the first pusher plate 431 to move.

[0038] In some examples, the first blocking mechanism 440 also includes a third drive member 442, which may be, for example, a cylinder. The third drive member 442 is connected to the placement platform 400 and is connected to the first baffle 441 and is used to drive the first baffle 441 to move.

[0039] In some examples, the second pusher mechanism 450 also includes a fourth drive member 452, which may be, for example, a cylinder. The fourth drive member 452 is connected to the placement platform 400 and is connected to the second pusher plate 451 and is used to drive the second pusher plate 451 to move.

[0040] In some examples, the packing table 500 includes a support plate 510 and a lifting device 520 connected to the support plate 510. The support plate 510 is used to place the packaging box 200, and the lifting device 520 is used to lift the support plate 510. After a layer of capacitors 100 is placed inside the packaging box 200 on the support plate 510, the lifting device 520 lowers the support plate 510 by a distance equivalent to that layer of capacitors 100, allowing the packing device to continue placing the next layer of capacitors 100 inside the packaging box 200. Flexible materials such as foam or pearl cotton can be used to separate different layers of capacitors 100. The packing table 500 can cooperate with other automatic flexible material placement devices to achieve fully automatic stacking and placement of capacitors 100.

[0041] In some examples, the packing device further includes a second blocking mechanism 460, which includes a second baffle 461. The second baffle 461 is disposed between the transfer channel 300 and the first side 401 of the placement table 400. The second baffle 461 can extend or retract relative to the placement table 400. When the second push plate 451 pushes the array of capacitors 100 to move, the second baffle 461 can extend from the placement table 400 and block the array of capacitors 100 on both sides, together with the first baffle 441, to prevent the array of capacitors 100 from deforming. The second blocking mechanism 460 may also include a fifth driving member 462, which may be, for example, a cylinder. The fifth driving member 462 is connected to the transfer channel 300 or the placement table 400, and is connected to the second baffle 461 and used to drive the second baffle 461 to move.

[0042] In some examples, the lifting device 520 includes a base 521, a first drive member 522, and a screw 523. The base 521 can be fixedly connected to the lower end of the placement platform 400. The first end of the screw 523 is connected to the support plate 510, and the second end of the screw 523 is movably connected to the base 521. The first drive member 522 is used to drive the screw 523 to move relative to the base 521. The first drive member 522 may include, for example, a motor and a nut driven by the motor to rotate. The nut engages with the screw 523, thereby driving the screw 523 to move up and down through the rotation of the nut. The lifting device 520 also includes a guide post 524. The first end of the guide post 524 is connected to the support plate 510, and the second end of the guide post 524 movably passes through the base 521 to improve lifting stability.

[0043] In some examples, the packing device also includes a first sensor 410, which is located on one side of the transfer channel 300 and outside the first pusher plate 431. The first sensor 410 is used to detect the capacitor 100 on the transfer channel 300. For example, it can detect whether the capacitor 100 on the transfer channel 300 opposite to the first pusher plate 431 is full. The first pusher mechanism 430 can be controlled to operate based on the detection result of the first sensor 410.

[0044] In some examples, the packing device also includes a second sensor 411, which is located on the side of the first baffle 441 away from the first push plate 431. The second sensor 411 is used to detect the position of the first baffle 441. When the first baffle 441 is at an extreme position away from the transfer channel 300, the second sensor 411 generates a signal, and the second push mechanism 450 and the second blocking mechanism 460 act according to the signal.

[0045] In some examples, the packing table 500 also includes a box positioning mechanism 511, which is mounted on the support plate 510. The box positioning mechanism 511 is used to contact at least one side of the packaging box 200 to prevent the packaging box 200 from moving. The box positioning mechanism 511 may be, for example, L-shaped, with one end fixed to the support plate 510 and the other end adjacent to the outer side of the packaging box 200.

[0046] In some examples, the packing device also includes a bridging mechanism 420, which is disposed on the placement platform 400 and close to the packing table 500. The bridging mechanism 420 includes a support plate 421 and a bridging plate 426 connected below the support plate. The support plate 421 extends toward the packing table 500 and is used to extend into the side opening 210 of the packaging box 200 to contact the inner wall of the packaging box 200, preventing the side wall of the packaging box 200 from collapsing inward toward the side opening 210 and affecting the entry of the capacitor 100 into the packaging box 200. The bridging plate 426 is used to be disposed between the placement platform 400 and the packing table 500 to prevent large gaps between the placement platform 400 and the packing table 500. The bridging plate 426 can press against the bottom wall of the packaging box 200, so that the capacitor 100 can move smoothly between the placement platform 400 and the packing table 500.

[0047] In some examples, the bridging mechanism 420 also includes a support 422 and a rotating member 423. The support 422 is connected to the display platform 400, and the rotating member 423 is rotatably disposed on the support 422. The expansion plate 421 is connected to the rotating member 423. By rotating the rotating member 423 and the expansion plate 421 thereon, the expansion plate 421 can be rotated to enter or leave the packaging box 200.

[0048] In some examples, the bridging mechanism 420 also includes a handle 424 and a connecting rod 425. The support 422, the rotating component 423 and the spreading plate 421 are each in pairs and are combined in a one-to-one correspondence and arranged opposite each other in the first direction. The handle 424 is located on one of the rotating components 423. The handle 424 is convenient for the operator to operate manually. The two rotating components 423 are connected by the connecting rod 425 to realize the linkage of the two sets of supports, rotating components 423 and spreading plates 421.

[0049] In some examples, the transport channel 300 includes a support frame 310 and a conveyor belt 320 mounted on the support frame 310. The support frame 310 can be fixed to the placement table 400. The transport channel 300 also includes a sixth drive member 340, which is mounted on the support frame 310 or the placement table 400 and is used to drive the conveyor belt 320 to move. The transport channel 300 also includes a stop block 330 at the end of the conveyor belt 320 to block the movement of the capacitor 100. The stop block 330 is equipped with a position sensor to detect whether the capacitor 100 in the transport channel 300 has reached the end of the transport channel 300. The first pushing mechanism 430 is adjacent to the stop block 330 at its end in the conveying direction of the transport channel 300.

[0050] In some examples, the conveyor belt 320 includes a feeding section and a pushing section arranged sequentially along the conveying direction of the transmission channel 300. The transmission channel 300 includes guardrails 350 on both sides of the feeding section to prevent the capacitor 100 from falling and to maintain the placement of the capacitor 100. A first pushing mechanism 430 is located on one side of the pushing section.

[0051] In some examples, the transport channel 300 also includes an inclined block 360 located at the starting point of the conveyor belt 320. The inclined block 360 is inclined downwards in the direction toward the conveyor belt 320 to facilitate the entry of the capacitor 100 into the conveyor belt 320. The transport channel 300 includes guardrails 350 located on both sides of the inclined block 360, which extend from both sides of the inclined block 360 to both sides of the feeding section.

[0052] Finally, it should be emphasized that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
