Description

Technical Field

[0001] This utility model relates to the field of PCB board inspection technology, and in particular to a PCB partition fixing device and a size measuring mechanism. Background Technology

[0002] In the automated dimensional measurement of PCB boards, lightweight partitions are typically placed between each layer to prevent scratches or collisions between stacked PCBs. During measurement, the robotic arm must first remove the partition under the PCB to be measured and temporarily store it to one side, then replace it after measurement. However, since the partitions are mostly made of engineering plastics and are relatively thin, they are easily displaced or even slipped during the removal process due to airflow or equipment vibration, causing subsequent operations to be interrupted and reducing measurement efficiency. In addition, traditional temporary storage methods lack effective fixing and detection methods, requiring the robotic arm to repeatedly adjust the position when picking up and placing the partitions, increasing operation time and affecting the stability and efficiency of the overall automated process.

[0003] Currently, common methods for fixing partitions, such as magnetic clamps or mechanical clips, have limitations in applicability. For example, they cannot be used with non-metallic partitions or obstruct the operating area of ​​robotic arms. While existing vacuum adsorption solutions can provide some fixing effect, they consume a lot of energy and lack intelligent detection functions, making it difficult to meet the requirements of high-precision and high-efficiency automated measurement.

[0004] In summary, in the existing technology, when using lightweight partitions to temporarily store PCB boards, the lack of fixation makes the lightweight partitions prone to displacement, which affects the temporary storage of the PCB boards. Utility Model Content

[0005] The purpose of this utility model is to provide a PCB partition fixing device and a size measuring mechanism to solve the problem in the prior art that when using lightweight partitions to temporarily store PCB boards, the lack of fixing causes the lightweight partitions to easily shift, affecting the temporary storage of the PCB boards.

[0006] To achieve the above objectives, this utility model provides a PCB partition fixing device, which includes a machine base and a fixing component. The fixing component consists of a support platform and an adsorption component. The support platform is disposed on the machine base, and the adsorption component is disposed below the support platform. The adsorption component includes a vacuum generator, which is disposed below the support platform, and one end of the vacuum generator is connected to a gas supply end.

[0007] The end face of the support platform is provided with multiple air holes, and a vacuum suction cup is provided below each air hole. Each vacuum suction cup is connected to the end of the vacuum generator away from the air supply end through an air pipe.

[0009] An electromagnetic valve is installed between the vacuum generator and the gas supply end, and the electromagnetic valve is connected to the photoelectric switch signal.

[0010] The support platform has a storage space underneath, which is used to place the transformer.

[0011] The machine is equipped with a cooling fan on its side wall, which corresponds to the storage space.

[0012] The machine tool is also provided with a viewing window on its side wall, which corresponds to the storage space.

The loading trolley is arranged on one side of the measuring component, and the unloading trolley is arranged on one side of the fixing component.

The machine base is used to place the fixing component and provide a support platform. The fixing component is used to fix the partitions that need to be temporarily stored.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figure 1 and Figure 2 This utility model provides a PCB partition fixing device, which includes a machine base 101 and a fixing component. The fixing component consists of a support platform 102 and an adsorption component. The support platform 102 is disposed on the machine base 101, and the adsorption component is disposed below the support platform 102. The adsorption component includes a vacuum generator 103, which is disposed below the support platform 102. One end of the vacuum generator 103 is connected to an air supply end.

[0023] In this embodiment, the machine base 101 is used to place the fixing component and provide a support platform. The fixing component is used to fix the partition that needs to be temporarily stored. The bearing platform 102 provides a placement surface for the temporary storage partition. The adsorption component adsorbs the partition. Specifically, the vacuum generator 103 provides a power source for adsorbing the partition. Non-destructive fixing is achieved through negative pressure adsorption, thereby adapting to the fixing of partitions of different sizes. This avoids the problems of adhesive residue requiring frequent cleaning and adhesion decay leading to fixing failure after long-term use, and also avoids the problem that mechanical negative pressure chambers require the partition to completely cover the cavity opening to be effective, which imposes strict requirements on the precision of partition placement.

[0024] Furthermore, the end face of the support platform 102 is provided with a plurality of air holes 104, and a vacuum suction cup 105 is provided below each air hole 104. Each vacuum suction cup 105 is connected to the end of the vacuum generator 103 away from the air supply end through an air pipe.

[0025] In this embodiment, the vacuum generator 103 provides a power source for the adsorption partition, and the vacuum suction cups 105 flexibly contact the surface of the partition, achieving non-destructive fixation through negative pressure adsorption. The distributed layout adapts to partitions of different sizes. By using the vacuum generator 103 in conjunction with the distributed vacuum suction cups 105 to adsorb the partition, the problems of adhesive residue requiring frequent cleaning and adhesion decay leading to fixation failure after long-term use are avoided. It also avoids the problem of mechanical negative pressure chambers requiring the partition to completely cover the cavity opening to be effective, which imposes stringent requirements on the precise placement of the partition. It is worth noting that multiple vacuum generators 103 can be provided (only one is shown in the figure).

[0026] Furthermore, the end face of the support platform 102 is provided with an opening 106, and the adsorption component also includes a photoelectric switch 107. The photoelectric switch 107 is disposed below the opening 106, and the optical axis of the photoelectric switch 107 is oriented towards the central region of the support platform 102.

[0027] Furthermore, a solenoid valve is provided between the vacuum generator 103 and the gas supply end, and the solenoid valve is signal-connected to the photoelectric switch 107.

[0028] In this embodiment, the optical axis of the photoelectric switch 107 is used to detect whether the partition covers the designated area of ​​the support platform 102, and the output signal controls the start and stop of adsorption, realizing the intelligent control logic of "adsorption with plate, standby without plate", avoiding energy consumption caused by ineffective adsorption; the solenoid valve switches the gas path on and off according to the signal of the photoelectric switch 107, controls the start and stop of the vacuum generator 103, realizes the energy-saving mode of supplying gas on demand, and reduces dust accumulation caused by continuous adsorption.

[0029] Furthermore, a storage space 108 is provided below the support platform 102, which is used to place the transformer.

[0030] In this embodiment, the storage space 108 can be used to place a transformer, which is used to power the entire machine 101. The compact layout reduces interference from external cables and improves the overall integrity of the equipment.

[0031] Furthermore, a cooling fan 109 is also provided on the side wall of the machine 101, and the cooling fan 109 corresponds to the storage space 108.

[0032] In this embodiment, by setting the cooling fan 109, the temperature rise of the vacuum generator 103 and the transformer in the storage space 108 during long-term operation can be reduced, preventing performance degradation caused by overheating.

[0033] Furthermore, the side wall of the machine 101 is also provided with a viewing window 110, which corresponds to the storage space 108.

[0034] In this embodiment, the visual window 110 allows operators to visually inspect the status of internal components, and the material of the visual window 110 is an acrylic sheet.

[0035] Furthermore, the bottom of the machine base 101 is also provided with casters 111, which are universal casters with locking function.

[0036] In this embodiment, the movable wheels 111 enable the entire device to move flexibly within the production line, adapting to the needs of multi-station collaboration.

[0037] In summary, during use, the stacked PCB boards to be tested are placed on the loading station side of the machine 101. First, the top PCB board is moved to the testing table, and then the partition below it is placed on the support platform 102. After the photoelectric switch 107 senses the edge of the partition's arrival signal, it sends a trigger command to the solenoid valve, activating the vacuum generator 103 to generate a negative pressure airflow. This airflow is then distributed by the vacuum suction cups 105 to form a uniform adsorption force field, thus fixing the partition across the entire area. After the current PCB board measurement is completed, the tested board is transferred to the unloading temporary storage area. Then, the vacuum adsorption is released, and the partition temporarily stored on the support platform 102 is extracted and placed on the surface of the tested PCB board to construct a protective layer. The system achieves seamless connection between the partition placement and measurement processes through the time-series linkage control of photoelectric signals and vacuum adsorption. At the same time, the cooling fan 109 runs continuously to maintain the system's thermal balance, ensuring adsorption stability under continuous operation.

[0038] Please see Figure 3The present invention also provides a size measuring mechanism, including the PCB partition fixing device as described above, and further including a measuring component 201, a robotic arm 202 and a storage component. The measuring component 201 is located on one side of the machine base 101, the robotic arm 202 is located above the machine base 101, and the storage component includes a loading trolley 203 and a unloading trolley 204. The loading trolley is disposed on one side of the measuring component 201, and the unloading trolley 204 is disposed on one side of the fixing component.

[0039] In this embodiment, the measuring component 201 performs high-precision measurement of PCB dimensions, which is existing technology and will not be described in detail here. The robotic arm 202 realizes precise picking and placing of the partition and PCB board, and the path planning needs to be synchronized with the adsorption sequence of the fixing device. The loading trolley 203 centrally stores the PCB boards to be tested, and its proximity to the measuring station shortens the picking stroke. The unloading trolley 204 receives the measured PCB boards, and its adjacent layout with the PCB partition fixing device realizes the optimization of the "picking up partition - measuring PCB - placing partition" cycle.
