[0047] The content of the utility model will be further described in detail in combination with specific embodiments:

[0048] As shown in Figure 1 , Figure 2 and Figure 3 , a power supply automatic assembly test line, comprising a fixedly arranged rack, the rack is provided with a conveying assembly 1, a riveting assembly 2 and a labeling assembly 3.

[0049] The conveying assembly 1 comprises a speed-up chain mechanism, which is used for carrying a carrier 4, and a product is arranged on the carrier 4. The product is composed of an upper cover and a lower cover. As shown in Figure 9 and Figure 10 , the carrier 4 is arranged in a plate-shaped structure, comprising a main carrier 41 and a sub-carrier 42 carried on the main carrier 41. The edge of the main carrier 41 is provided with an anti-collision glue for reducing damage caused by knocking. The main carrier 41 is provided with two clamping grooves 43, and the sub-carrier 42 is clamped in the clamping grooves 43. The sub-carrier 42 is used for carrying the product and is provided with a plurality of different structures according to the product specifications, and the bottom of the sub-carrier 42 is hollow.

[0050] The speed-up chain mechanism is arranged in a double-layer structure, comprising a top layer speed-up chain 11 and a bottom layer speed-up chain 12. The top layer speed-up chain 11 carries the product to pass through the riveting station and the labeling station in the first direction in turn, and the bottom layer speed-up chain 12 runs in the opposite direction to recycle the carrier 4.

[0051] The top layer speed-up chain 11 is provided with a pushing mechanism, which comprises a pushing device 14 reciprocating in the first direction and a pushing driving mechanism driving the pushing device 14 to run. The top end of the pushing device 14 is lower than the lower surface of the carrier 4 carried on the upper layer speed-up chain mechanism, so that the pushing device 14 can pass from below the carrier 4.

[0052] As shown in Figure 4 and Figure 5As shown, the pusher 14 comprises a pusher body 142, which is provided with a groove 143 at the top end, and a push head 141 movably arranged in the groove 143. The push head 141 is provided with a trapezoidal vertical cross section, comprising an upper bottom edge 1411, an inclined edge 1412 and a lower bottom edge 1413 arranged in sequence in a first direction. The upper bottom edge 1411 is hingedly connected to the pusher 14, so that the entire push head 141 can rotate around the hinge end and be accommodated in the pusher body 142. In this embodiment, a limiting stopper is arranged below the upper bottom edge 1411. When the lower bottom edge 1413 of the push head 141 abuts against the carrier 4, the limiting stopper keeps the push head 141 at a preset fixed angle. In addition, the push head 141 is also provided with a reset mechanism, which is arranged as a counterweight arranged on the other side of the hinge end relative to the lower bottom edge 1413. In this way, the torque generated by the counterweight at the hinge end is opposite to the torque generated by the push head 141 at the hinge end, and is greater than the torque generated by the push head 141 at the hinge end.

[0053] When the pusher 14 moves in the first direction under the drive of the driving mechanism, the push head 141 abuts against one side of the carrier 4 and pushes the carrier 4 to run in the first direction. When the pusher 14 moves in the direction opposite to the first direction, the inclined edge 1412 of the push head 141 abuts against another carrier 4, which presses the push head 141 into the pusher 14, so that the pusher 14 passes under the carrier 4. When the pusher 14 runs to the other side of the carrier 4, the push head 141 pops out and abuts against the carrier 4. At this time, the pusher 14 can push the carrier 4 to run in the first direction when the pusher 14 runs in the first direction.

[0054] As shown in Figure 2 and Figure 3 , the speed chain mechanism is provided with a carrier 4 lifting mechanism 13 at both ends. The carrier 4 carrying the product on the top speed chain 11 is sequentially subjected to riveting and labeling operations and then runs to the end of the top speed chain 11, and is transported to the bottom speed chain 12 by the carrier 4 lifting mechanism 13 arranged there, and then is conveyed in the opposite direction by the bottom speed chain 12 to the other carrier 4 lifting mechanism 13, so as to re-transport the carrier 4 to the starting end of the top speed chain 11, thereby completing the recycling of the carrier 4.

[0055] The carrier 4 lifting mechanism 13 comprises a lifting platform 131 arranged in the horizontal direction for carrying the carrier 4. The lifting platform 131 is vertically slidably arranged on a lifting frame 132 under the action of a driving mechanism, so as to realize the transfer of the carrier 4 between the two layers of speed chain mechanisms.

[0056] As shown in Figure 6 , the riveting assembly 2 is correspondingly arranged at the riveting station. It comprises an upper die holder 21 and a lower die holder 22, a punch mechanism 23 for performing riveting operation on the upper and lower covers of the product, a pre-pressing plate 241 and a demolding plate 251.

[0057] The punch mechanism 23 includes an upper punch 231 fixed to the upper die holder 21 and a lower punch 232 fixed to the lower die holder 22 corresponding to the upper punch 231.

[0058] The pre-pressing plate 241 is arranged parallel to the upper die holder 21 and connected to the upper die holder 21 through a pair of pre-pressing guide columns and a pair of first buffer devices 242. The first buffer devices 242 leave a certain gap between the pre-pressing plate 241 and the upper die holder 21, which allows the pre-pressing plate 241 to move towards the upper die holder 21 during the riveting operation.

[0059] The demolding plate 251 is arranged parallel to the pre-pressing plate 241 and connected to the lower die holder 22 through four demolding guide columns and second buffer devices 252 sleeved outside the demolding guide columns. The second buffer devices 252 leave a certain gap between the demolding plate 251 and the lower die holder 22, which allows the demolding plate 251 to move towards the lower die holder 22 during the riveting operation.

[0060] The upper die holder 21 is fixed with the positioning head 26 adjacent to the position of the upper punch 231 in the vertical direction. The lower end of the positioning head 26 is tapered and cooperates with the positioning hole on the product during the riveting operation, which is used for precise positioning of the product.

[0061] A plurality of through holes are formed in the demolding plate 251 in the vertical direction, which are respectively penetrated by the positioning head 26 and the lower punch 232. During the riveting operation, when the second buffer device 252 is compressed to the shortest, the lower punch 232 penetrates the corresponding through hole of the demolding plate 251, and the top end of the lower punch 232 is higher than the top end of the demolding plate 251 by a preset process distance, which is the riveting depth of the lower punch 232 during the riveting operation.

[0062] When the riveting operation is performed, the carrier 4 carries the product into the space between the upper die holder 21 and the lower die holder 22, and then the lower die holder 22 moves upwards to lift the product through the hollow structure of the sub-carrier 42, so that the product is separated from the carrier 4. The riveting force is not borne by the carrier 4 during the riveting operation, which avoids damaging the carrier 4. The upper die holder 21 drives the pre-pressing plate 241 to move towards the lower die holder 22 under the action of the booster cylinder. The pre-pressing plate 241 first contacts the upper cover of the product, and the first buffer device 242 deforms until it enters the maximum buffer stroke, which gives the pre-pressing plate 241 a certain pressure on the upper cover of the product, so that the upper cover of the product is horizontally positioned at the first station to achieve preliminary positioning. When the four positioning heads 26 directly position the upper cover of the product, one end of the upper cover of the product is lifted. Then, the four positioning heads 26 enter the four positioning holes pre-formed in the product to precisely position the product.

[0063] Subsequently, the upper punch 231 applies a riveting force to the product upper cover, and the riveting force is transmitted to the stripping plate 251, so that the second buffer device 252 is deformed, and the stripping plate 251 moves towards the lower die seat 22 to buffer the riveting force and realize flexible riveting. At the same time, the lower punch 232 passes through the through hole on the stripping plate 251 and protrudes from the top end of the stripping plate 251 by a preset process length, and the product lower cover is riveted.

[0064] In the process of the punch mechanism 23 being separated from the product, and the process of the second buffer mechanism 252 returning to the initial state to strip the product. The first buffer device 242 also gradually returns to the initial state, and the pre-pressing plate 241 still applies a pressing force to the product, and the upper and lower covers of the product after riveting are pressed in the third station to prevent the riveting part of the product from adhering to the punch mechanism 23, thereby causing the product to jump.

[0065] As shown in Figure 7 , the rubberizing assembly is correspondingly arranged at the rubberizing station. In the embodiment, the rubberizing assembly is arranged as two, which are respectively used for pasting product labels and bar code labels. Any rubberizing assembly includes a feeding mechanism 31 and a labeling mechanism 32. The feeding mechanism 31 includes a material shaft 311 and a label stripping plate 312. The material shaft 311 is arranged in the horizontal direction, and a label tape formed by a plurality of labels is wound on the material shaft 311.

[0066] The label stripping plate 312 is correspondingly arranged on the material shaft 311 and is used for carrying the label tape. The upper end surface of the label stripping plate 312 is horizontal and is provided with a suction hole. The suction hole is communicated with a negative pressure to realize suction of the centrifugal paper on the back of the label. When the labeling mechanism 32 takes out the label to be taken, the label stripping plate 312 moves synchronously along the horizontal direction towards the material shaft 311, and simultaneously strips the centrifugal paper on the label to be taken, and the labeling mechanism 32 simultaneously takes out the label to be taken.

[0067] As shown in Figure 8 , the labeling mechanism 32 includes a labeling base 321, which is fixed above the top-speed chain 11 in a second direction perpendicular to the first direction. The labeling base 321 is provided with a labeling support 322, which is used for connecting and driving the labeling head 323 to move. The labeling support 322 slides in the second direction under the action of a driving mechanism. The labeling support 322 includes a first support arranged in the horizontal direction on the labeling base 321. The first support is provided with a second support in the vertical direction. The second support slides on the first support in the first direction. The second support is provided with the labeling head 323 in the vertical direction. The labeling head 323 can move up and down on the second support. In addition, the labeling head 323 is connected with the second support through a rotating motor 3233, so that the labeling head 323 can rotate along the vertical axis, and thus the labeling head 323 has four degrees of freedom.

[0068] The labeler 323 is provided with an adsorber 3231 and a rolling wheel 3232. The adsorber 3231 is parallel to the rolling wheel 3232, and is driven by the labeler 322 to the label stripping plate 312, and the label is adsorbed by the adsorption force of the adsorber 3231, and is carried to slide on the corresponding position of the product surface. At the same time, the rolling wheel 3232 is driven by the labeler 322 to roll on the surface of the label, remove the bubbles, and make the label close to the product surface. The rolling wheel 3232 is connected with the labeler 322 through the vertically arranged rolling spring, and when the rolling spring is in the stretched state, the outer edge of the rolling wheel 3232 is lower than the adsorption end of the adsorber 3231.
