Technical Field

[0002] For electronic products, the PCB motherboard is one of the important components. Before being assembled into electronic products, it needs to be processed separately. The PCB motherboard usually needs to be processed by dispensing glue or pasting copper foil. Since these two operations require high precision, the PCB board needs to be placed in a carrier dedicated to the processing equipment. In order to avoid shaking and offset of the processed products, the dedicated carrier usually has a small tolerance, so that the product swings less in the dedicated carrier. After the processing is completed, it is usually necessary to carry out the unloading process to transfer the processed PCB board to a blister box dedicated to unloading, in preparation for the next packaging and unloading.

[0003] In order to pack and discharge materials, the tolerance of the product placement in the blister box is usually larger than that of the dedicated carrier. In the material transfer process, usually one by one is manually picked out from the dedicated carrier and placed in the blister box dedicated for discharge. Since the tolerance of the blister box is inconsistent with that of the dedicated carrier, it can only be placed in the blister box by manual observation with the naked eye, and precise positioning cannot be achieved. In addition, the efficiency of material transfer is low, which is not conducive to improving the competitiveness of the enterprise. Utility Model Content

[0023] The scissor frame assembly includes a plurality of connecting rods 33 and hinge pins 34, each connecting rod 33 is provided with a through hole at both ends and in the middle, a plurality of connecting rods 33 are arranged in pairs to form an X-shaped combination, and the plurality of X-shaped combinations are connected end to end by hinge pins 34, so that a plurality of deformable quadrilaterals are formed between the connecting rods 33, the connecting rods 33 can rotate around the hinge pins 34, a plurality of suction cup material picking assemblies are matched with the plurality of X-shaped combinations one by one, and the suction cup material picking assemblies are arranged in the middle of the X-shaped combination and connected by the hinge pins 34.

[0024] Through the combination of multiple X-shaped tail connections, a linkage structure is formed to drive multiple suction cup material picking components to adjust the spacing at the same time.

[0025] The multi-station automatic variable-distance material transfer mechanism further comprises a reference distance adjustment member 35 , which is arranged and fixedly connected to the suction cup material taking assembly at the side farthest from the variable-distance driving device 32 .

[0028] The guide block 42 cooperates with the guide rod to guide the suction cup material taking assembly through relative sliding.

[0029] There are four suction cup material picking assemblies, which include a suction cup material picking rack 40 and multiple material picking suction cups 41. Multiple material picking suction cups 41 are arranged on the suction cup material picking rack 40 at equal intervals.

[0030] The material transfer efficiency can be effectively improved by taking materials through four suction cups.

The first guide rod 36 and the third guide rod 38 cooperate with the first suction cup material picking assembly and the third suction cup material picking assembly for guidance, respectively, and the second guide rod 37 and the fourth guide rod 39 cooperate with the second suction cup material picking assembly and the fourth suction cup material picking assembly for guidance, respectively.

[0032] The guide rods cooperate with each other in pairs, so that the movement process of the suction cup material picking assembly is more stable.

[0033] The first suction cup material picking assembly, the second suction cup material picking assembly, the third suction cup material picking assembly and the fourth suction cup material picking assembly are arranged in sequence from left to right, and the first guide rod 36, the second guide rod 37, the third guide rod 38 and the fourth guide rod 39 are arranged in sequence from front to back.

[0034] The first guide rod 36 , the second guide rod 37 , the third guide rod 38 and the fourth guide rod 39 are arranged in sequence from front to back so that the guiding effect is more stable.

[0035] The multi-axis driving module includes a Z-axis driving module 4 and an X-axis driving module 5 .

[0041] The variable pitch drive device 32 is a variable pitch cylinder.

[0042] The working process of the multi-station automatic variable-distance material transfer mechanism provided in this embodiment is as follows: Compared with the existing processing methods, the embodiment of the utility model provides the advantages of higher material transfer accuracy and high material transfer efficiency.

[0043] First, the personnel starts the device and clicks the reset button on the controller 2 to put the device into reset standby state.

[0044] The personnel manually places the blister box 7 on the blister box installation position, and performs position calibration and fixation through the movable adjustment block 6 . After the calibration is completed, the start button on the controller 2 is clicked.

[0045] The X-axis driving module 5 drives the variable-length material taking module 3 to move horizontally. When the variable-length material taking module 3 moves to the top of the dedicated carrier, the Z-axis driving module 4 drives the variable-length material taking module 3 to move downward, and the material taking suction cup 41 vacuum absorbs the material.

[0046] After the material taking action is completed, the Z-axis driving module 4 controls the variable-distance material taking module 3 to rise and return to the initial position.

[0049] The reference spacing adjustment member 35 is a manually adjustable minimum spacing for small range adjustment, and the spacing placed in the blister box 7 is automatically stretched by the variable pitch cylinder. As for the stretched spacing, the stroke of the variable pitch cylinder can be manually changed to achieve the purpose of variable pitch.

[0050] After the pitch change is completed, the X-axis drive module 5 drives the variable pitch material picking module 3 to move to the right. After moving to the blister box installation position, the Z-axis drive module 4 drives the variable pitch material picking module 3 to descend, the suction cup material picking assembly releases the material, the material discharge action is completed, and the Z-axis drive module 4 returns to its initial position.

[0051] Transfer the material in this cycle and repeat the previous actions.

[0052] From the above, it can be seen that the beneficial effect of the utility model is: the use of its mechanism can effectively solve the problems of low material transfer accuracy and low material transfer efficiency in the prior art of PCB board processing and manual material transfer. By using this product structure, the multi-axis drive module can control the variable distance material picking module 3 to perform flexible and accurate material transfer, and through the cooperation of the variable distance component and the suction cup material picking component, the relative distance between the suction cup material picking components is changed, thereby further improving the flexibility of material transfer, which is beneficial to improving the competitiveness of the enterprise.

The scope of the present utility model includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
