[0037] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a panel collecting and packing machine, comprising a frame 1, a delivery device 2, a lifting device 3 and a conveying device 4. The delivery device 2 is arranged on the frame 1, and is used to provide a desiccant bag. The lifting device 3 is arranged on the frame 1, and comprises a supporting frame 31 and a lifting drive mechanism 32. The supporting frame 31 is used to support a packaging box with multiple storage spaces, and the lifting drive mechanism 32 is used to drive the supporting frame 31 to move up and down. The conveying device 4 is arranged on the frame 1, and comprises a load-bearing frame 41, a conveying drive mechanism 42 and a pushing mechanism 43. The load-bearing frame 41 is used to carry products to be boxed, and can be moved to a position corresponding to the delivery device 2 or the packaging box under the drive of the conveying drive mechanism 42. The pushing mechanism 43 is used to push the product to be boxed carried on the load-bearing frame 41 into one of the multiple storage spaces of the packaging box.

[0039] In a specific application, each packaging box is provided with a plurality of horizontal plates and a plurality of vertical plates, and the plurality of horizontal plates and the plurality of vertical plates are staggered horizontally and vertically to form a plurality of storage spaces. When the board collecting and packing machine is working, first, the conveying drive mechanism 42 drives the carrier 41 to move to correspond to the discharge end of the PCBA production line, so that the produced PCBA board can be transferred to the carrier 41; secondly, the conveying drive mechanism 42 drives the carrier 41 to move to correspond to the packaging box on the support frame 31. In the process of the conveying drive mechanism 42 driving the carrier 41 to move to correspond to the support frame 31, the carrier 41 passes through the discharge end of the feeding device 2, and the feeding device 2 feeds the desiccant. Then, the pushing mechanism 43 pushes the PCBA board on the carrier 41 into one of the multiple storage spaces of the packaging box on the supporting frame 31, and then repeats the above actions until the multiple storage spaces at the same height are all filled with PCBA boards; finally, the lifting drive mechanism 32 drives the supporting frame 31 to move the packaging box to the height of one storage space, so that the packaging box does not contain PCBA boards and the multiple storage spaces at the same height correspond to the pushing mechanism 43, and then repeats the above actions to achieve the goal of loading PCBA boards into all the storage spaces in the packaging box.

[0040] Specifically, the above-mentioned delivery device 2 can adopt a vibration plate, and the conveying drive mechanism 42 can adopt a synchronous belt linear module.

[0041] Specifically, the lifting drive mechanism 32 includes two guide rods 321, a ball screw 322, a ball nut 323, a lifting drive motor and a lifting platform 324. The two guide rods 321 are arranged in parallel on the frame 1. The ball screw 322 is rotatably arranged on the frame 1 and is parallel to the two guide rods 321. The ball nut 323 is sleeved on the ball screw 322 and screwed to the ball screw 322. The output shaft of the lifting drive motor is connected to one end of the ball screw 322. The lifting platform 324 is sleeved on the two guide rods 321 and connected to the ball nut 323. The support bracket 31 is arranged on the lifting platform 324. In a specific application, the lifting drive motor generates a driving force to drive the ball screw 322 to rotate, the ball screw 322 drives the ball nut 323 to move, and the ball nut 323 drives the lifting platform 324 to move along the length direction of the two guide rods 321, thereby driving the support bracket 31 to be lifted and lowered.

[0042] like Figure 3 and Figure 4As shown, the above-mentioned pushing mechanism 43 includes a guide rail 431, a slider 432, two synchronous wheels 433, a synchronous belt, a pushing drive motor 434, a rotating shaft 435, a push rod 436 and an angle limiter. The guide rail 431 is laid on the carrier 41. The slider 432 is slidably set on the guide rail 431. The two synchronous wheels 433 are both rotatably set on the carrier 41 and are respectively located on both sides of the guide rail 431. The synchronous belt is wound around the two synchronous wheels 433 and connected to the slider 432. The pushing drive motor 434 is set on the carrier 41, and its output shaft is connected to one of the two synchronous wheels 433. One end of the rotating shaft 435 is rotatably set on the slider 432. The push rod 436 is connected to the other end of the rotating shaft 435. The angle limiter is connected to the rotating shaft 435. In a specific application, after the conveying drive mechanism 42 drives the carrier 41 to align with the support frame 31, the angle limiter drives the rotating shaft 435 to rotate, causing the push rod 436 to rotate to align with the PCBA board on the carrier 41. Then, the push drive motor 434 generates a driving force to drive one of the two synchronous wheels 433 to rotate. The two synchronous wheels 433 rotate the synchronous belt, and the synchronous belt drives the slider 432 to slide along the guide rail 431, thereby driving the push rod 436 to move and push the PCBA board into the storage space. Specifically, the angle limiter can be a motor.

[0043] In some preferred embodiments, the carrier 41 includes two opposing support plates 411 that are movable relative to each other, thereby varying the distance between the two support plates 411. In specific applications, by disposing two relatively movable support plates 411 on the carrier 41, the two support plates 411 can support PCBAs of different widths.

[0044] Specifically, the two support plates 411 are connected by two guide rods 44 , and one of the two support plates 411 can slide along the two guide rods 44 , so that the distance between the two support plates 411 is changed.

[0045] In some preferred embodiments, the carrier 41 is provided with a plurality of rotating wheels 412 arranged in a straight line. When the product to be boxed is placed on the carrier 41, it abuts against the rotating wheels 412. In specific applications, when the push rod 436 pushes the PCBA to move, the rotating wheels 412 can reduce friction between the PCBA and the carrier 41, preventing friction from affecting the PCBA.

[0046] In some preferred embodiments, the angle limiting member includes a first limiting rod 437, a second limiting rod 438, and a limiting block 439. The first limiting rod 437 is disposed on the slider 432. The second limiting rod 438 is disposed on the support frame 41 and is lower than the first limiting rod 437. The limiting block 439 is connected to the rotating shaft 435 and movably abuts against the first limiting rod 437 or the second limiting rod 438.

[0047] When the slider 432 is moved back to the default state, the limit block 439 abuts against the second limit rod 438. When the synchronous belt drives the slider 432 to move, the limit block 439 separates from the second limit rod 438, and the rotating shaft 435 rotates under the action of the push rod 436. When the limit block 439 abuts against the first limit rod 437, the push rod 436 stops rotating. At this time, the push rod 436 corresponds to the PCBA board on the carrier 41. As the slider 432 continues to move toward the lifting device 3, the push rod 436 pushes the PCBA board into the storage space. Then, the synchronous belt drives the slider 432 to move back to the default state in the opposite direction. The limit block 439 abuts against the second limit rod 438 again, and the angle of the push rod 436 can be limited without a motor.

[0048] like Figure 5 As shown, in some preferred embodiments, the above-mentioned board collecting and packing machine further includes a conveyor device 5, the feed end of which faces the discharge port of the feeding device 2, and the discharge end of the conveyor device 5 faces the conveying device 4. In specific applications, the feeding device 2 causes the desiccant pack to fall onto the conveyor device 5. When the conveying drive mechanism 42 drives the carrier 41 to move to the position corresponding to the support bracket 31 and passes the discharge end of the conveyor device 5, the conveyor device 5 transfers the desiccant pack to the PCBA board on the carrier 41.

[0049] Specifically, the transmission device 5 includes a transmission frame 51, two transmission rollers 52, a transmission belt 53, and a transmission drive motor 54. The transmission frame 51 is arranged on the frame 1. The two transmission rollers 52 are arranged parallel to the transmission frame 51. The transmission belt 53 is wound around the two transmission rollers 52. The transmission drive motor 54 is arranged on the transmission frame 51, and its output shaft is connected to one of the two transmission rollers 52. In specific applications, the transmission drive motor 54 generates a driving force to drive the two transmission rollers 52 to rotate, and the two transmission rollers 52 drive the transmission belt 53 to rotate, thereby driving the desiccant pack that falls from the discharge port of the vibrating plate onto the transmission belt 53 to move to the PCBA board that falls on the carrier frame 41.

[0050] In some preferred embodiments, the discharge end of the conveyor device 5 is provided with a guide member having a gradually decreasing opening. Specifically, the guide member includes two guide plates 55 , which are disposed opposite each other. An opening is formed between the two guide plates 55 , and the opening gradually decreases along the conveying direction of the conveyor belt 53 . This guide member guides the desiccant pack, ensuring that the desiccant pack lands precisely on the PCBA board on the carrier 41 .

[0051] In some preferred embodiments, the above-mentioned pallet collecting and cartoning machine also includes a transfer device 6, which includes a box supply mechanism 61 and a box receiving mechanism 62. A conveying mechanism 33 is provided on the support frame 31, and the lifting drive mechanism 32 can drive the conveying mechanism 33 to correspond to the box supply mechanism 61 or the box receiving mechanism 62. When the conveying mechanism 33 corresponds to the box supply mechanism 61, the box supply mechanism 61 transfers the empty packaging box to the conveying mechanism 33. When the conveying mechanism 33 corresponds to the box receiving mechanism 62, the conveying mechanism 33 transfers the packaging box filled with products to the box receiving mechanism 62.

[0052] In specific applications, the functions and operating principles of the box supply mechanism 61, the box receiving mechanism 62 and the conveying mechanism 33 are consistent. The following takes the box supply mechanism 61 as an example to specifically illustrate the functions and operating principles of the box supply mechanism 61 and the box receiving mechanism 62.

[0053] Specifically, the conveying mechanism 33 includes a conveying frame 331, a conveying rod 332, a conveying driving wheel 333, a plurality of first conveying driven wheels 334, a plurality of second conveying driven wheels 335, a plurality of conveying chains, and a conveying motor 336. The conveying frame 331 is set on the lifting platform 324. The conveying rod 332 is rotatably set on the conveying frame 331. The conveying driving wheel 333 is fixed on the conveying rod 332. The plurality of first conveying driven wheels 334 are all fixed on the conveying rod 332. The plurality of second conveying driven wheels 335 are all rotatably set on the conveying frame 331 and are respectively opposite to the plurality of first conveying driven wheels 334. Each conveying chain is wound around the corresponding first conveying driven wheels 334 and the second conveying driven wheels 335. A driving gear is provided on the output shaft of the conveying motor 336, and the driving gear is connected to the conveying driving wheel 333 by a chain.

[0054] In specific applications, the transmission motor 336 generates a driving force to drive the driving gear to rotate, and the driving gear drives the transmission driving wheel 333 to rotate through the chain. The transmission driving wheel 333 drives multiple first transmission driven wheels 334 to rotate through the transmission rod 332. The multiple first transmission driven wheels 334 drive multiple second transmission driven wheels 335 to rotate through multiple transmission chains, thereby driving the packaging boxes placed on multiple transmission chains to move.

[0055] It should be noted that the conveying rack 331 of the box supply mechanism 61 and the conveying rack 331 of the box receiving mechanism 62 are arranged one above and one below each other, so that the conveying mechanism 33 can correspond to the conveying rack 331 of the box supply mechanism 61 or the conveying rack 331 of the box receiving mechanism 62 under the action of the lifting drive mechanism 32, thereby realizing automatic loading and unloading of packaging boxes.

[0056] In some preferred embodiments, the above-mentioned plate collecting and cartoning machine also includes a recycling device 7, which includes a placement rack 71, an up and down moving drive mechanism 72 and a material moving mechanism 73. The placement rack 71 is used to place a recycling box with multiple recycling spaces, the up and down moving drive mechanism 72 is used to drive the placement rack 71 to move up and down, and the material moving mechanism 73 is used to push the defective products transported by the conveying device 4 into one of the multiple recycling spaces of the recycling box.

[0057] In specific applications, the structure and operating principle of the placement rack 71 are consistent with the structure and operating principle of the support rack 31, the structure and operating principle of the up and down moving drive mechanism 72 are consistent with the structure and operating principle of the lifting drive mechanism 32, and the structure and operating principle of the material moving mechanism 73 are consistent with the structure and operating principle of the material pushing mechanism 43, which will not be repeated here.

[0058] It should be noted that the material moving mechanism 73 is arranged above the support frame 31. When the conveying drive mechanism 42 drives the PCBA board on the carrier frame 41 to move, the detection device will detect the PCBA board. The PCBA board that passes the inspection will be pushed into the storage space of the packaging box by the pushing mechanism 43. If the PCBA board fails the inspection, the lifting drive mechanism 32 drives the support frame 31 to move downward, so that the material moving mechanism 73 corresponds to the pushing mechanism 43. The pushing mechanism 43 pushes the unqualified PCBA board to the pushing mechanism 43, and then the pushing mechanism 43 pushes it into the packaging box on the recovery device 7.

[0059] To sum up, in one or more embodiments of the present invention, the plate collecting and packing machine of the present invention realizes the automatic delivery of desiccant packages and automatic packing of products through the cooperation of the delivery device, the lifting device and the conveying device, which not only reduces the labor intensity of workers but also improves the packaging speed.

[0060] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
