Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to a circuit board whole tray taking device. Background Art

[0002] With the continuous development of science and technology, electronic products such as smart phones, smart watches, and tablet computers have become an important part of people's daily lives. Flexible circuit boards are widely used in line connections due to their excellent flexibility. Therefore, the demand for flexible circuit boards has also increased. At the same time, while today's smart devices require high performance, they also need to have a smaller size and weight, and have higher requirements for product integration, and circuit performance cannot be guaranteed 100%. Therefore, the detection and production efficiency of flexible circuit boards have become the key considerations for manufacturers. Under higher efficiency and speed testing, automated testing has increased the demand for UPH (production capacity, generally refers to output per hour), and traditional general feeding methods cannot meet this test form.

[0003] In automated testing, circuit board products cannot be tested directly. The product needs to be placed on a carrier and tested at the corresponding points of the circuit board through pressing and pinning techniques. When multiple lines are tested synchronously, all loading and unloading tasks are completed by loading and unloading robotic arms. Currently, the commonly used material-retrieving mechanism is a single-actuator single-head or double-head, which is used with vision and can tolerate material-retrieving deviations. It is commonly used to retrieve 4PCS (pieces / items) or 8PCS at the same time, and can also be used for single-retrieving work. Negative pressure adsorption is used for loading and unloading flexible circuit boards. The vacuum is provided by a vacuum generator, but its loading requirements cannot meet the ultra-high test UPH requirements of multi-PCS multi-line synchronous testing; therefore, on this basis, the number of robotic arms will be increased to form a ping-pong loading and unloading form. The loading speed can theoretically be increased by 1 times, but its cost is also increased by nearly 1 times accordingly. If you want to continue to increase UPH, it is difficult to continue to increase.

[0004] Therefore, the material taking equipment in the prior art cannot load multiple pieces, especially a whole tray of workpieces, at one time, and cannot meet higher loading requirements. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] See also Figure 1-3 ,in Figure 1 This is the overall structural diagram of the circuit board tray reclaiming device. Figure 2 A schematic diagram of the structure of the suction mechanism provided in this embodiment, Figure 3 for Figure 2 The schematic diagram of the method of part A in the figure, a circuit board whole tray material removal device provided in this embodiment includes:

[0029] Moving mechanism 1; and

[0030] The suction mechanism 2 is arranged on the moving mechanism 1, and the moving mechanism 1 can drive the suction mechanism 2 to approach or move away from the material tray 3 to be grasped; the suction mechanism 2 includes a suction nozzle mounting plate 21 and a plurality of suction nozzle assemblies 22, the suction nozzle mounting plate 21 is arranged at the moving end of the moving mechanism 1, the suction nozzle assembly 22 is composed of a plurality of suction nozzles 221, and a plurality of groups of the suction nozzle assemblies 22 are mounted on the suction nozzle mounting plate 21, and the suction nozzles 221 belonging to the same suction nozzle assembly 22 are connected to the same air chamber 4, and the suction nozzles 211 are uniformly controlled by the same air chamber 4 to suck the circuit board 100 on the material tray 3.

[0031] It can be understood that the circuit board whole tray picking device in this embodiment can be set on the mounting platform and fixed as a whole, and the suction mechanism 2 can be moved close to the material tray 3 by the moving mechanism 1. For example, in this embodiment, the moving mechanism 1 is fixed on the mounting base 5, and the mounting base 5 can be fixed on the mounting platform. More possible common implementation methods will not be further described here.

[0032] It can be understood that the suction nozzles 221 on the several suction nozzle assemblies 22 on the suction mechanism 2 in this embodiment can be designed in advance according to the size specifications of the actual material tray 3, so that the flexible circuit boards on the material tray 3 can be sucked by the corresponding suction nozzles 221. The specific adjustments can be designed by those skilled in the art according to actual needs and will not be further described here.

[0033] In this embodiment, the suction nozzle 221 is preferably a flexible suction nozzle. The flexible suction nozzle can avoid rigid contact with the circuit board when contacting the circuit board, and at the same time will not cause excessive pressure to damage the circuit board product, and also avoid frequent operation failures and stops, thereby improving the reliability and stability of the equipment.

[0034] It can be understood that in this embodiment, the suction nozzles 221 of the same group of suction nozzle assemblies 22 are separately arranged in the same air chamber 4, so that the positive and negative pressures of the same group of suction nozzles can be guaranteed, and the stability of the vacuum value can be ensured. At the same time, the products can be sucked in different areas to avoid the entire tray of circuit boards being sucked incorrectly when individual suction nozzles have problems, thereby ensuring the stability and reliability of the work.

[0035] It can be understood that the arrangement and installation method of several groups of suction nozzle assemblies 22 can be set according to the placement of the circuit boards on the material tray 3. For example, the suction nozzle assemblies 22 in this embodiment are arranged in a column combination, which is mainly based on realizing the whole tray grabbing of multiple circuit boards on the material tray 3. More arrangement and layout methods are not further described here, and technical personnel in this field can make adjustments according to actual needs.

[0036] In this embodiment, if Figure 2 As shown, the suction nozzle mounting plate 21 is provided with a plurality of the air chambers 4 , and the suction nozzles 221 are connected to the air chambers 4 .

[0037] It can be understood that the air chamber 4 can be directly set by digging a groove on the nozzle mounting plate 21, and can also be set by externally welding the air chamber 4. In the present embodiment, the air chamber 4 is directly set by digging a groove on the nozzle mounting plate 21. In other embodiments, the air chamber 4 can be added externally and combined with the nozzle mounting plate 21. Further description is not given here.

[0038] In this embodiment, each of the air chambers 4 is provided with an individual air supply pipeline. The air supply pipeline is mainly a general pipeline, which is mainly connected to an external vacuum pump for vacuuming or conveying gas, so that the suction nozzle forms a negative pressure suction and a positive pressure release action. It can be understood that each air chamber 4 is provided with an individual air supply pipeline, which can evenly ensure the air supply or vacuum amount of each air chamber 4, and ensure that the overall suction effect is balanced and stable. In addition, it can be understood that a switch control, such as a valve, can be provided between the individual air supply pipeline of each air chamber 4 and the total air supply pipeline, so as to facilitate the shutdown of the corresponding air chamber 4 when the suction nozzle assembly 22 corresponding to a single air chamber 4 has a problem or does not need to work. The air supply pipeline and the control switch can use conventional pipelines and switch valves, which are not illustrated here. Those skilled in the art can understand and implement it based on the above description and the prior art.

[0039] In this embodiment, if Figure 2 As shown, a sealing plate 41 and a sealing member 42 are provided on the air chamber 4 , and the sealing member 42 is provided between the sealing plate 41 and the air chamber 4 .

[0040] It is understandable that the sealing plate 41 can be installed and fixed at the opening of the air chamber 4 by means of conventional screws, bolts or other threaded fittings. The specific shape and structure of the sealing plate 41 can be designed according to the structure of the opening of the air chamber 4, which will not be further described here. In addition, the sealing member 42 can be a conventional sealing component such as a sealant or a sealing ring, which is mainly used to ensure the sealing effect after the sealing plate 41 is installed and fixed to prevent vacuum leakage.

[0041] In this embodiment, if Figure 2 As shown, each sealing plate 41 is individually provided with an air pipe joint 43 , and the air supply pipeline is connected to the air pipe joint 43 .

[0042] It is understandable that the trachea connector 43 can be a conventional product in the prior art, which will not be further described herein. Meanwhile, the trachea connector 43 can be installed on the sealing plate 41 by conventional threaded fitting or integrated, which will not be further constrained or described herein.

[0043] In addition, in other embodiments, the air pipe connector 43 may be disposed at other locations, such as on the nozzle mounting plate 21, as long as it can be connected to the air chamber 4, which will not be further described here.

[0044] In this embodiment, two air pipe joints 43 are provided on each sealing plate 41 , and the two air pipe joints 43 are distributed at two ends of the sealing plate 41 .

[0045] like Figure 2As shown, a trachea connector 43 is provided at both ends of the sealing plate 41 corresponding to each group of nozzle assemblies 22. By providing two trachea connectors 43, the positive and negative pressures of the nozzles 221 in the same group can be controlled evenly and quickly. It can be understood that the number of trachea connectors 43 can be set according to the length of the air chamber 4 and the number of nozzles corresponding to each air chamber 4, and the implementation method of providing more than two trachea connectors 43 will not be further expanded here.

[0046] In this embodiment, the air pipe joint 43 is connected to a vacuum pump, which is used to provide negative pressure to the suction nozzle. The air supply pipeline between the vacuum pump and the air pipe joint 43 is provided with a switch device, which is used to control the on-off of the air supply pipeline.

[0047] It is understandable that the vacuum pump is a conventional device, and its working principle and structure will not be further described here. Those skilled in the art can choose to set it according to actual needs. At the same time, using a vacuum pump as a negative pressure source can continuously provide negative pressure for the suction nozzle, and a vacuum solenoid valve can be used to control the on and off, so that the vacuum air chamber 4 of different suction nozzle assemblies 22 can be switched on and off, and the working state of the suction nozzle can be realized in different partitions. At the same time, because the vacuum flow of the vacuum pump is much larger than that of the vacuum generator, it can be achieved that even if a small number of suction nozzles fail to successfully suck the product, the vacuum degree of each vacuum chamber will not drop sharply, and the work of the remaining suction nozzles will not be affected, thereby improving the working stability of the device.

[0048] Furthermore, the switch device can be a conventional solenoid valve, pneumatic valve, etc., which will not be further described here. By setting the switch device, when the nozzles of some groups fail or do not need to work, the corresponding nozzle assembly 22 can be peeled off through the switch device, thereby improving the flexibility of the device.

[0049] In this embodiment, the moving mechanism 1 includes a driving member 11, a slider guide rod mechanism 12 and a module mounting plate 13, the driving member 11 and the slider guide rod mechanism 12 are arranged on the module mounting plate 13, the driving member 11 is used to drive the slider of the slider guide rod mechanism 12 to move, and the suction mechanism 2 is arranged on the slider of the slider guide rod mechanism 12.

[0050] It can be understood that the driving member 11 is mainly used to drive the slider to move. In this embodiment, the driving member 11 can be driven by a servo motor. In other embodiments, the driving can also be achieved by a pneumatic, hydraulic or other telescopic mechanism, which will not be further described here. The slider guide rod mechanism 12 is mainly composed of a guide rod and a slider. Its basic principle and common form belong to conventional means in the field, which will not be further described here. Those skilled in the art can select and implement it according to the above description.

[0051] In this embodiment, the suction mechanism 2 also includes a nozzle mounting side plate 23, and the nozzle mounting side plate 23 is arranged on the slider of the slider guide rod mechanism 12, and the nozzle mounting plate 21 is arranged on the nozzle mounting side plate 23, and a reinforcing rib 24 is arranged between the nozzle mounting plate 21 and the nozzle mounting side plate 23.

[0052] It can be understood that, through the combination of the nozzle mounting side plate 23, the nozzle mounting plate 21 and the reinforcing ribs 24, the stability of the overall structure can be enhanced, so that the overall mechanism can be more stable and maintain accuracy during operation.

[0053] In this embodiment, a guide member 25 is provided on the suction nozzle mounting plate 21 , and the guide member 25 can be inserted into the guide hole 31 of the material tray 3 so that the suction nozzle 221 is aligned with the circuit board to be sucked on the material tray 3 .

[0054] like Figure 3 As shown, a guide member 25 is provided on the nozzle mounting plate 21. Meanwhile, in the present embodiment, the end of the guide member 25 is conical, and a guide hole 31 is provided on the corresponding material tray 3. Then, when the material tray 3 is sucked, when the nozzle approaches the circuit board to be sucked, the guide member 25 on the nozzle mounting plate 21 is inserted into the guide hole 31 of the material tray 3, so as to form a positioning that facilitates the nozzle to align with the circuit board to be sucked.

[0055] The working process and principle of the circuit board whole tray material taking device of the utility model:

[0056] When loading is required, the moving mechanism 1 drives the nozzle mounting plate 21 and other components to move downward, and the guide member 25 is inserted into the guide hole 31 of the material tray 3 to complete the positioning. After reaching the material picking height, the solenoid valve is controlled to open, and the vacuum pump generates negative pressure, so that the nozzle of the nozzle assembly 22 forms a negative pressure. After the vacuum degree reaches the required requirement, the circuit board is sucked, and the moving mechanism 1 moves the nozzle mounting plate 21 up to the upper limit and stops. At this time, the vacuum suction state is maintained; when discharging is required (placed on another material tray 3 or other carrier), the moving mechanism 1 drives the nozzle mounting plate 21 and other components to move downward, and the guide member 25 is inserted into the guide hole 31 to complete the positioning. After reaching the discharging height, the solenoid valve is switched, the nozzle mouth is positively pressurized, and the product falls into the corresponding acupoint of the carrier.

[0057] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0058] The utility model provides a suction mechanism 2, which is composed of a suction nozzle mounting plate 21 and a plurality of suction nozzle assemblies 22. According to the number of circuit boards on a material tray 3, a plurality of suction nozzle assemblies 22 are provided to simultaneously suck the entire tray of circuit boards, thereby realizing rapid and large-scale grasping of circuit boards. For example, it can ensure that more than 100 PCS of flexible circuit boards can be taken and placed at the same time. Moreover, by making the suction nozzles on the plurality of suction nozzle assemblies 22 correspond to the same air chamber 4, respectively, it can ensure that the positive and negative pressures of the suction nozzles in the same group are guaranteed, and while ensuring the stability of the vacuum value, the products are sucked in different areas to avoid errors in the suction of the entire tray of circuit boards when a problem occurs with an individual suction nozzle. By using the guide member 25, a small range deviation of product taking and placing can be achieved, which can meet the customer's requirements for the stability of single large-scale testing as a whole, while greatly reducing the cost and improving the versatility of the structure.

[0059] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
