Description

Technical Field

[0001] The present invention relates to the technical field related to PCB production, and in particular to a board collecting machine used for alternately stacking and separating and framing materials. Background Art

[0002] PCB, also known as printed circuit board, is a carrier for the electrical connection of electronic components. In the process of PCB production and processing, in order to meet the needs of automated production, a PCB placing machine is usually used to place the PCBs horizontally one by one on the conveyor belt of the production line. When the PCB processing is completed, the PCBs on the conveyor belt of the production line are collected by a PCB collecting machine.

[0003] Alternate stacking of materials refers to optimizing the storage efficiency and access convenience of materials through reasonable stacking and storage methods in material management, while ensuring the safety and integrity of materials. This involves aspects such as material classification, identification, storage location arrangement, and storage and access operation specifications. Reasonable alternating stacking can avoid material confusion, improve work efficiency, ensure material traceability, and support the smooth progress of the production process.

[0004] At present, when PCB boards are stacked, in order to prevent the surface of two adjacent PCB boards from being scratched and damaged, isolation paper is placed between the two adjacent PCB boards. The isolation paper is used to isolate and protect the PCB boards. When the PCB board placing machine places the PCB boards, each time a board is taken out, the isolation paper needs to be taken away manually. This method has the problems of low automation, high labor cost and low production efficiency.

[0005] In addition, when the vacuum suction cup grabs the release paper, the corners of the release paper are prone to warping. After the release paper is placed on the PCB board, the release paper at the warped position is prone to folding, which may cause the possibility of scratches between two adjacent groups of PCB boards at the position where the release paper is folded, thereby affecting the normal processing of the PCB board.

DETAILED DESCRIPTION

[0062] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0063] like Figure 1-Figure 11 As shown, a board collecting machine for alternately stacking and separating and framing materials comprises a frame 1, a loading mechanism 2, a feeding mechanism 3, a PCB material frame 4, a collecting frame 5, an isolation paper material frame 6 and a material shifting mechanism 7, wherein the frame 1 is provided with a loading mechanism 2 for loading PCB boards and a feeding mechanism 3 for conveying the PCB boards; the PCB material frame 4 is provided on one side of the feeding mechanism 3 and a collecting frame 5 and an isolation paper material frame 6 are further provided on the other side of the PCB material frame 4; the material shifting mechanism 7 is provided on the upper ends of the feeding mechanism 3 and the PCB material frame 4, and comprises a gantry 71, a horizontal moving assembly 72 provided on the gantry 71, a first grabbing assembly 73 provided at the lower end of the horizontal moving assembly 72 and used for grabbing PCB boards, and a second grabbing assembly 74 provided at the lower end of the horizontal moving assembly 72 and used for grabbing isolation paper;

[0064] The PCB boards are transported to the feeding mechanism 3 under the drive of the loading mechanism 2, and the PCB boards are sent into the PCB material frame 4 one by one under the drive of the first grabbing component 73. Then, the first grabbing component 73 cooperates with the second grabbing component 74 to stack the PCB boards in the PCB material frame 4 and the isolation paper in the isolation paper frame 6 alternately inside the collection frame 5. Specifically, when the PCB material frame 4 and the isolation paper are respectively placed with a proper amount of PCB boards and isolation paper inside the isolation paper frame 6, the horizontal moving component 72 in the material moving mechanism 7 will simultaneously drive the first grabbing component 73 and the second grabbing component 74 to move. When the first grabbing component 73 moves to the upper end of the PCB material frame 4, the first grabbing component 7 3 extends into the interior of the PCB material frame 4 and grabs a PCB board. As the horizontal moving component 72 moves again, the first grabbing component 73 and the PCB board will move to the upper end of the collection frame 5. Then the first grabbing component 73 extends into the interior of the collection frame 5 and puts the PCB board into the interior of the collection frame 5. At the same time, the second grabbing component 74 is located at the upper end of the isolation paper material frame 6. The second grabbing component 74 will synchronously grab a piece of isolation paper. After the second grabbing component 74 moves to the upper end of the collection frame 5 again, the second grabbing component 74 will put the piece of isolation paper into the upper end of the PCB board inside the collection frame 5. This cycle is repeated to achieve alternating stacking of PCB boards and isolation papers.

[0065] Similarly, the first grabbing component 73 can also cooperate with the second grabbing component 74 to send the PCB boards and isolation papers alternately stacked inside the collection frame 5 into the PCB material frame 4 and the isolation paper material frame 6 respectively, thereby realizing the recycling of the isolation paper and facilitating the subsequent use of the isolation paper.

[0066] It should be noted that the feeding mechanism 2, the horizontal moving assembly 72 and other structures are commonly used in the prior art, and their specific structures are not repeated here.

[0067] Further, if Figure 4-Figure 7 As shown, the feeding mechanism 3 includes a support frame 31, a rotating shaft 32, a first driving unit 33, a supporting ring 34 and a centering unit 35. A plurality of groups of rotating shafts 32 are arranged side by side on the support frame 31, and the plurality of groups of rotating shafts 32 rotate synchronously under the drive of the first driving unit 33; each group of the rotating shafts 32 is provided with a plurality of supporting rings 34 for supporting the PCB board; the centering unit 35 is arranged at the lower end of the rotating shaft 32, and is used to center the PCB board on the supporting ring 34.

[0068] In detail, when the PCB board is transferred to the feeding mechanism 3, the first driving unit 33 works to drive the multiple sets of rotating shafts 32 to rotate synchronously, and the multiple sets of rotating shafts 32 will synchronously drive the multiple sets of supporting rings 34 to rotate synchronously, thereby driving the PCB board to move horizontally on the supporting rings 34.

[0069] It should be noted that the multiple groups of rotating shafts 32 rotate in the same direction and at the same speed through belt transmission.

[0070] Further, if Figure 5-Figure 7 As shown, the centering unit 35 includes a second driving unit 351, a rotating gear 352, a first rack 353, a second rack 354, a first moving block 355, a second moving block 356 and a push rod 357. The second driving unit 351 is arranged at the lower end of the support frame 31; the rotating gear 352 is arranged in transmission with the second driving unit 351; the paired first rack 353 and the second rack 354 are respectively connected to the rotating gear 352 in transmission; the paired first moving blocks 355 and the second moving blocks 356 are arranged in transmission with the rotating gear 352 in transmission. 55 and the second moving block 356 are fixedly connected to the first rack 353 and the second rack 354 respectively. Specifically, the first moving block 355 is fixedly connected to the first rack 353, and the second moving block 356 is fixedly connected to the second rack 354; the push rod 357 is provided with a plurality of groups and is fixedly set at the upper ends of the first moving block 355 and the second moving block 356, the upper ends of the push rods 357 are set between two adjacent groups of rotating shafts 32, and the top of the push rods 357 is provided with a rotating wheel 358.

[0071] Among them, since the PCB board will inevitably deviate when moving on the feeding mechanism 3, the PCB board can be corrected by setting the centering unit 35, so that different PCB boards can be located at the same position during the movement process. In this way, the first grabbing component 73 will grab the same position of the PCB board when grabbing the PCB board, which is conducive to the neat placement of the subsequent PCB boards.

[0072] In detail, after the PCB board moves to the upper end of the support ring 34, the second driving unit 351 works and drives the rotating gear 352 to rotate. The rotating gear 352 will synchronously drive the first rack 353 and the second rack 354 to move in the opposite direction, thereby driving the first moving block 355 and the second moving block 356 to move in the opposite direction. Finally, the push rods 357 on the first moving block 355 and the second moving block 356 will approach each other until the rotating wheel 358 at the upper end of the push rod 357 abuts against the PCB board, thus completing the deviation correction process of the PCB board.

[0073] Further, if Figure 8-Figure 10 As shown, the lower ends of the PCB material frame 4, the collection frame 5 and the isolation paper material frame 6 are all provided with a lifting mechanism 8, which includes a third driving unit 81, a lifting screw 82, a lifting plate 83, a lifting guide rod 84 and a lifting support plate 85. The output end of the third driving unit 81 is transmission connected to the lifting screw 82; the lifting plate 83 is transmission-arranged with the lifting screw 82 and at least one group of lifting guide rods 84 is fixedly arranged on the lifting plate 83; the lifting support plate 85 is fixedly arranged at the upper end of the lifting guide rod 84.

[0074] Among them, by setting up the lifting mechanism 8, the PCB board or isolation paper inside the PCB material frame 4, the collection frame 5 and the isolation paper material frame 6 can be lifted up, and then the first grabbing component 73 or the second grabbing component 74 can be used to complete the grabbing work of the PCB board or isolation paper.

[0075] In detail, when the grabbing work is performed, the third driving unit 81 works and drives the lifting screw 82 to rotate. Due to the transmission setting of the lifting screw 82 and the lifting plate 83, the lifting plate 83 and the lifting guide rod 84 will rise synchronously and drive the lifting support plate 85 to rise. Subsequently, the lifting support plate 85 will lift the PCB board or isolation paper inside the PCB material frame 4, the collection frame 5 or the isolation paper material frame 6 upwards.

[0076] It should be noted that a group of opposing beam sensors 100 are provided on the outer sides of the upper ends of the PCB material frame 4, the collection frame 5 and the isolation paper material frame 6. In this way, when the lifting mechanism 8 drives the uppermost PCB board or isolation paper inside the PCB material frame 4, the collection frame 5 or the isolation paper material frame 6 to move to the height of the opposing beam sensor 100, the lifting mechanism 8 can suspend its work. At this time, the uppermost PCB board or isolation paper can be quickly grabbed by the first grabbing component 73 or the second grabbing component 74.

[0077] Further, if Figure 3 As shown, an ion wind rod 200 is fixedly installed at the lower end of the gantry 71, and the air outlet of the ion wind rod 200 is arranged toward the PCB material frame 4, the collection frame 5 and the isolation paper material frame 6. The ion wind rod 200 can quickly remove foreign matter and dust on the surface of the object, and neutralize the static electricity on the surface of the object, thereby achieving the purpose of eliminating static electricity.

[0078] Further, if Fig.11 As shown, the first grabbing assembly 73 has the same structure as the second grabbing assembly 74, and respectively includes a first lifting unit 731 connected to the horizontal moving assembly 72, a support plate 732 fixedly arranged at the lower end of the first lifting unit 731, and a plurality of groups of vacuum suction cups 733 arranged at the lower end of the support plate 732.

[0079] It should be noted that, on the one hand, the setting of the first lifting unit 731 is to make the vacuum suction cup 733 descend and approach the PCB board or the isolation paper. On the other hand, after the second grasping component 74 completes the grasping of a piece of isolation paper, the first lifting unit 731 can drive the vacuum suction cup 733 to move back and forth and then drive the isolation paper to shake. The purpose of driving the isolation paper to shake is to shake off the excess isolation paper that may be stuck on the lower end of the isolation paper, so as to avoid the vacuum suction cup 733 grabbing two or more isolation papers at a time. Example

[0080] The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0081] Further, if Figure 12-13 As shown, a straightening mechanism 9 is also provided on one side of the isolation paper material frame 6, which includes an upper straightening component 91 located at the upper end of the isolation paper and a lower straightening component 92 located at the lower end of the isolation paper. The upper straightening component 91 and the lower straightening component 92 clamp the isolation paper and straighten the isolation paper.

[0082] Among them, by arranging a straightening mechanism 9 on one side of the isolation paper material frame 6, after the material transfer mechanism 7 grabs the isolation paper, the two ends of the isolation paper can be straightened in cooperation with the straightening mechanism 9 to avoid excessive warping of the two ends of the isolation paper. In this way, after the isolation paper is stacked, the two ends of the isolation paper will not be folded, thereby ensuring the normal stacking effect between the PCB boards.

[0083] Further, if Figure 13-14 As shown, the upper straightening assembly 91 includes a lifting assembly 911, a translation assembly 912, a screed plate 913 connected to the translation assembly 912, and a straightening roller 914;

[0084] The lifting assembly 911 includes a fixed plate 9111, at least one set of second lifting units 9112 disposed on the fixed plate 9111, and a moving plate 9113 connected to the second lifting units 9112;

[0085] The upper straightening assembly 91 has the same structure as the lower straightening unit, and the two are arranged opposite to each other.

[0086] In detail, before the second grabbing component 74 grabs a piece of isolation paper, the translation component 912 will drive the smoothing plate 913 and the straightening roller 914 away from the isolation paper to prevent the isolation paper from interfering with the smoothing plate 913 or the straightening roller 914 during the lifting process. After the second grabbing component 74 completes the grabbing of a piece of isolation paper, the horizontal moving component 72 and the second grabbing component 74 will suspend work, thereby causing the isolation paper to hover for a short period of time to facilitate the straightening mechanism 9 to work. Subsequently, the lifting component 911 in the upper straightening component 91 and the lower straightening component 92 will cooperate with the translation component 912 to drive the smoothing plate 913 and the straightening roller 914 close to the isolation paper until the isolation paper is clamped between the upper and lower smoothing plates 913 and the straightening roller 914, and then the straightening work can be performed.

[0087] Further, if Figure 14-16As shown, the translation assembly 912 includes a fourth driving unit 9121, a bidirectional threaded rod 9122, a fourth driving unit 9121, a connecting rod 9124, a first slider 9125, a second slider 9126 and a slide bar 9127, the fourth driving unit 9121 is fixedly arranged with the moving plate 9113; the bidirectional threaded rod 9122 is transmission-connected with the fourth driving unit 9121 through a transmission belt 9123, the bidirectional threaded rod 9122 is connected with the moving plate 9113 through at least one group of connecting rods 9124, the bidirectional threaded rod 9122 is provided with a first threaded portion 91221 and a second threaded portion 91222 with opposite rotation directions; the first slider 9125 and the second slider 9126 are transmission-connected with the first threaded portion 91221 and the second threaded portion 91222 respectively; one end of the slide bar 9127 is fixedly connected with the first slider 9125 or the second slider 9126, and the other end is slidingly connected with the fixed plate 9111;

[0088] The screed plate 913 is fixedly mounted on the first slider 9125 or the second slider 9126 , and the straightening roller 914 is rotatably connected to the first slider 9125 or the second slider 9126 .

[0089] In detail, during operation, first, the fourth driving unit 9121 works and drives the bidirectional threaded rod 9122 to rotate through the transmission belt 9123, thereby driving the first slider 9125 and the second slider 9126 to approach each other, until the smoothing plate 913 and the straightening roller 914 are driven close to one side of the vacuum suction cup 733 in the second grabbing assembly 74, and then the second lifting unit 9112 works and drives the smoothing plate 913 and the straightening roller 914 to be close to the isolation paper, and then the fourth driving unit 9121 works in the opposite direction, which can drive the smoothing plate 913 and the straightening roller 914 in the first slider 9125 and the second slider 9126 to move away from each other, thereby achieving the straightening of the two ends of the isolation paper, until the smoothing plate 913 and the straightening roller 914 are separated from the isolation paper, and the second grabbing assembly 74 can continue to work.

[0090] It should be noted that the fixing plates 9111 in the upper straightening assembly 91 and the lower straightening assembly 92 are both fixed on one side of the isolation paper material frame 6 .

[0091] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
