Description

Technical Field

[0001] The utility model relates to a circuit board staggering device, in particular to a circuit board double-row staggering machine for performing high-efficiency staggering operations. Background Art

[0002] The PCB production process usually includes a punching and forming step, through which multiple PCB product units on the PCB motherboard can be punched and formed. The punched products are scattered on the workbench or conveyor belt and need to be placed on the PCB tray for collection for the next step.

[0003] In the prior art, one method of placing products on a tray is to place the products on the tray manually. When the tray is full, the tray is moved to a storage location. This manual method of placing products on the tray is inefficient and is prone to uneven placement. Another method of placing products on the tray is to use a placing machine to place products on the tray automatically. However, the existing automatic placing machines use a manipulator (such as a suction cup) to directly suck the formed products from the punching and forming equipment to place the products on the tray. This automatic placing method not only has a low placing efficiency but also affects the processing efficiency of punching and forming. Summary of the invention

[0004] In view of the problems existing in the prior art, the main purpose of the utility model is to provide a double-row circuit board staggering machine which has high staggering efficiency and occupies little space.

[0005] In order to achieve the above main purpose, the utility model provides a circuit board double-row plate placing machine, including a frame, a product conveying device, a tray conveying device and a plate placing device; wherein:

[0006] The product conveying device, the pallet conveying device and the plate swinging device are installed on the frame, the pallet conveying device includes a loading assembly, a conveying assembly and a receiving assembly, the loading assembly is used to place an empty pallet on the conveying assembly, the conveying assembly is used to move the empty pallet to the plate swinging position and convey the pallet filled with products to the receiving assembly after the plate swinging is completed, wherein the conveying direction of the pallet is consistent with that of the product;

[0007] The pan-swing device comprises an X-axis moving module and a Y-axis moving module moving in the horizontal direction, a Z-axis moving module moving in the vertical direction, and a grabbing mechanism, wherein the grabbing mechanism can move in the X-axis, Y-axis and Z-axis directions to grab the product on the product conveying device and place it on the tray located at the pan-swing position;

[0008] There are two pallet conveying devices, namely a first pallet conveying device and a second pallet conveying device arranged on opposite sides of the product conveying device; there are two swinging plate devices, namely a first swinging plate device and a second swinging plate device, the first swinging plate device is used to place products on the pallet conveyed by the first pallet conveying device, and the second swinging plate device is used to place products on the pallet conveyed by the second pallet conveying device; wherein, along the conveying direction of the product, the first swinging plate device and the second swinging plate device are staggered.

[0009] In the above technical scheme, the plate-staging device enables the grasping mechanism to move in three dimensions through the actions of the X-axis moving module, the Y-axis moving module and the Z-axis moving module, and places the products on the product conveying device on the pallet located at the plate-staging position. After the pallet is full of products, the conveying component conveys it to the receiving component, the loading component places the empty pallet on the conveying component, the conveying component conveys the empty pallet to the plate-staging position, and the grasping mechanism places the next pallet, thereby realizing automatic plate-staging and receiving of products.

[0010] When in use, one end of the product conveying device can be connected or matched with the previous process equipment (such as punching equipment), and the products processed by the previous process equipment are conveyed to the position to be grasped by the product conveying device. The products at the position to be grasped can be automatically placed on the plate by the plate-staggering device. During the plate-staggering process, the previous process equipment can still operate normally, and will not affect the processing efficiency of the previous process equipment. Furthermore, by setting two pallet conveying devices and two plate-staggering devices, and arranging the two plate-staggering devices in a staggered manner along the conveying direction of the product, not only can the space occupied by the equipment be effectively reduced, but also the two plate-staggering stations can be operated simultaneously without affecting each other, so as to further improve the plate-staggering efficiency.

Figure 2 As shown, the product conveying device also includes a cleaning component 32, which is arranged upstream of the swinging device in the conveying direction of the conveyor belt. The cleaning component can be an ion blower to clean the product before swinging the plate and blow away dust and other impurities on the product.

[0033] Combination Figures 1 to 5 As shown, the two swing plate devices are respectively a first swing plate device and a second swing plate device. Along the conveying direction of the product (the X-axis direction in the embodiment), the first swing plate device and the second swing plate device are staggered. Specifically, the second swing plate device can be located at the downstream side of the first swing plate device, so that the operations of each other will not affect each other, so as to improve the swing plate efficiency. The first swing plate device can be installed on the support frame 12 and the support frame 13, and the second swing plate device can be installed on the support frame 14 and the support frame 13.

[0034] In the embodiment, the structures of the first swing plate device and the second swing plate device can be the same. Specifically, the first swing plate device may include an X-axis moving module 72, a Y-axis moving module 62, and a Z-axis moving module 42, and the grabbing mechanism 82 is arranged below the Z-axis moving module 42. The Y-axis moving module 62 of the first swing plate device is arranged on the support frame 12, and can drive the X-axis moving module 72 to reciprocate along the Y-axis direction. One end of the X-axis moving module 72 is connected to the Y-axis moving module 62, and the other end is supported on the sliding track side plate 132 of the support frame 13.

One end of the X-axis moving module 74 is connected to the Y-axis moving module 64, and the other end is supported on the sliding track side plate 134 of the support frame 13. The X-axis moving module 74 can drive the Z-axis moving module 44 to reciprocate along the X-axis direction on the screw rod 741, and the Z-axis moving module 44 can drive the grabbing mechanism 84 to reciprocate along the Z-axis direction 4.

[0036] Furthermore, if Figure 1 As shown, the inner side surface of the top wall of the housing is equipped with a first positioning camera 22 located above the first plate swinging device and a second positioning camera 24 located above the second plate swinging device, that is, the second positioning camera 24 is located at the downstream side of the first positioning camera 22 in the product conveying direction. During operation, after there are products to be plated in the working ranges of the first plate swinging device and the second plate swinging device, the conveyor belt stops conveying, the first positioning camera 22 and the second positioning camera 24 locate the products, and the grabbing mechanisms of the first plate swinging device and the second plate swinging device grab the products and place them on the tray at the plate swinging position.

[0037] See also Figure 4 and Figure 6 The Z-axis moving module 42 of the first swing plate device may include a Z-axis lifting screw 421, the vacuum generator 821 of the grabbing mechanism 82 is arranged on the side of the Z-axis moving module 42, and the suction cup 823 for grabbing the product is located below the Z-axis moving module 42. The grabbing mechanism 82 also includes a suction cup moving mechanism 822 (such as a cylinder lifting mechanism), which can further adjust the movement of the suction cup 823 in the vertical direction. The first swing plate device may have a detection camera arranged on the Z-axis moving module 42.

[0038] The Z-axis moving module 44 of the second swing plate device includes a Z-axis lifting screw 441, a vacuum generator 841 of the grabbing mechanism 84 is arranged on the side of the Z-axis moving module 44, a suction cup 843 for grabbing the product is located below the Z-axis moving module 44, and the grabbing mechanism 84 also includes a suction cup moving mechanism 842, which can further adjust the movement of the suction cup 843 in the vertical direction. The detection camera 442 of the second swing plate device can be arranged on the Z-axis moving module 42.

[0039] In this embodiment, the grabbing mechanism uses a plurality of suction cups. In other embodiments, the grabbing mechanism may also be a single suction cup or other clamping structure. Preferably, the first swing plate device and the second swing plate device are both provided with a plurality of suction cups to simultaneously grab and place a plurality of products. The Z-axis moving modules of the first swing plate device and the second swing plate device may also be provided with a rotating drive mechanism that drives the grabbing mechanism to rotate in the Z-axis direction, so as to facilitate the suction cup to grab the product and adjust the horizontal position of the product, thereby improving the accuracy of the plate arrangement.

[0040] In the embodiment, the first pallet conveying device 52 and the second pallet conveying device 54 may have the same structure. The basic structure of the pallet conveying device is briefly described below by taking the second pallet conveying device 54 as an example. Figure 7 and Figure 8 As shown, the second pallet conveying device 54 may include a loading assembly 541, a conveying assembly 542 and a receiving assembly 543. The loading assembly 541 and the receiving assembly 543 have the same structure, except that during operation, the loading assembly places the stacked empty pallets on the conveying assembly 542 from bottom to top, while the receiving assembly 543 stacks and collects the pallets on the conveying assembly 542 from bottom to top.

[0041] Taking the loading assembly 541 as an example, it includes a support plate 5411, a telescopic bearing member 5412, and a screw motor 5413 for driving the support plate 5411 to rise and fall. Among them, the stacked empty pallets can be carried by the telescopic bearing member 5412, and the screw motor 5413 drives the support plate 5411 to rise and fall in coordination with the telescopic bearing member 5412 to rise and fall, so that the stacked empty pallets can be placed on the conveying assembly 542 from bottom to top. Specifically, during operation, the screw motor 5413 first drives the support plate 5411 to rise to a position that can bear the empty pallet, and then the telescopic bearing member 5412 shrinks, and then the screw motor 5413 drives the support plate 5411 to drop the height of a pallet, and the telescopic bearing member 5412 then extends to carry the remaining stacked pallets, and the bottom pallet remains on the support plate 5411, and the screw motor 5413 drives the support plate 5411 to fall so that the bottom pallet enters the conveying assembly for transportation. In an embodiment, the telescopic bearing member 5412 may be driven by a cylinder to perform telescopic movement, but the present invention is not limited thereto.

[0042] In the embodiment, the conveying assembly 542 includes two track side plates 5422 with conveyor belts 5421 installed, and an adjustment structure 5425 for adjusting the distance between the two track side plates 5422. Among them, the adjustment structure 5425 can be a distance adjustment mechanism using a bidirectional screw rod, and the two track side plates 5422 are respectively threaded with the bidirectional screw rod. Further, the conveying assembly 542 is provided with a fixing mechanism for fixing the pallet during the plate swinging process, and the fixing mechanism includes a positioning support plate 5423 that can be lifted and lowered to the plate swinging position to carry the pallet and a clamping mechanism 5424 for fixing the pallet on the positioning support plate 5423. During operation, the conveying belt 5421 first transports the empty pallet to the plate swinging position, and then the positioning support plate 5423 rises and cooperates with the clamping mechanism 5424 to achieve the clamping and positioning of the pallet. After the plate swinging is full of products, the positioning support plate 5423 descends so that the pallet is continuously transported by the conveying assembly 542 to the receiving assembly.

[0043] When the embodiment of the utility model is used for the plate swinging, the product on the conveyor belt moves forward along the conveying direction to reach the position to be grabbed (the area on the conveyor belt corresponding to the grabbing range of the plate swinging device), at which time the conveyor belt stops, and the two plate swinging devices respectively absorb and grab the products on the conveyor belt, and further place the products on the pallet that has been transported to the plate swinging position by the two pallet conveying devices. After the products at the position to be grabbed are placed on the pallet, the conveyor belt continues to transport the products to the position to be grabbed, and the plate swinging device continues to place them until the pallet is full of products, and then the conveying component transports the full pallet to the receiving component. At the same time, the loading component can place an empty pallet on the conveying component and the conveying component transports the pallet to the plate swinging position for the next product placement.

[0044] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the scope of the present invention. Any person skilled in the art can make some improvements without departing from the scope of the present invention, that is, any changes or improvements made according to the present invention should be covered by the protection scope of the present invention.
