Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically a suction cup type PCB board handling device. Background Technology

[0002] A PCB, or Printed Circuit Board, is an important electronic component. It's created by printing and etching processes on an insulating substrate to form conductive lines and connection points for electronic components, thus providing a carrier for electrical connections. Simply put, a PCB is like a city's transportation network; electronic components are like the buildings in the city, and the conductive lines on the PCB are like the roads connecting these buildings, ensuring the smooth transmission of electronic signals and electrical energy between the components.

[0003] The precision and stability of manual handling are difficult to guarantee. PCB boards typically have high precision requirements, especially in precision processing steps such as surface mount technology (SMT). During manual operation, the strength and range of motion of the human hand are difficult to control precisely, which can easily cause physical damage such as collisions and scratches to the PCB board during handling. Inaccurate placement can also affect subsequent processing, soldering, or inspection processes. For example, when placing the PCB board on the worktable of a pick-and-place machine, even a slight positional deviation can lead to misplacement of surface mount components, resulting in a large number of scraps, increased production costs, and reduced product quality. Utility Model Content

[0004] The purpose of this invention is to provide a suction cup type PCB board handling device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a suction cup type PCB board handling device, including a support frame, a support platform, a material handling suction cup assembly disposed above the support frame; a cylinder disposed above the support frame; a mounting block disposed above the support frame and fixedly mounted on the telescopic end of the cylinder; an air pump fixedly mounted on one side of the mounting block; multiple suction cup bodies fixedly mounted on the bottom of the mounting block; an air vent pipe disposed between the air pump and the top of the suction cup body; and a positioning sensor disposed on the mounting block.

[0006] Furthermore, a support platform is provided at the bottom of the support frame, and suction cup transport slides are symmetrically arranged on the support frame.

[0007] Furthermore, a mounting bracket is fixedly installed on the top of the cylinder, and the mounting bracket is slidably connected to the suction cup transport slide.

[0008] Furthermore, a first unloading suction cup is slidably connected to the suction cup transport slide, and the first unloading suction cup is located on the right side of the infeed suction cup assembly.

[0009] Furthermore, a placement platform is fixedly installed on the top of the support frame, and the feeding and conveying suction cup assembly is positioned above the placement platform.

[0010] Furthermore, a Y-direction unloading suction cup is provided on the right side of the first unloading and transporting suction cup, and the PCB board body is located at the bottom end of the suction cup body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the equipment is ready before handling. Upon receiving the instruction, the air pump draws air to create negative pressure on the suction cup body, while the cylinder moves the mounting block downwards, bringing the suction cup body close to the PCB board. Upon contact, the positioning sensor detects and provides feedback. If the adsorption is unsatisfactory, the control system adjusts the cylinder stroke or the air pump power. If adsorption is successful, the cylinder moves upwards, and the suction cup is moved to the target position via the transmission components. The air pump then releases air to release the adsorption, and the PCB board is placed in position. After the process is completed, the equipment is ready to proceed. The support platform stably supports the equipment throughout the process. This design minimizes the risk of physical damage such as collisions or scratches to the PCB board body during handling, and avoids affecting subsequent processing, welding, or inspection procedures due to inaccurate placement.

[0013] 2. In this utility model, the mounting bracket is slidably connected to the suction cup transport slide, so that the position of the mounting bracket can be flexibly adjusted according to actual needs. At the same time, it is beneficial for the equipment to adapt to different production and handling requirements. By adjusting the position of the mounting bracket on the suction cup transport slide, the number and layout of suction cups can be easily replaced or increased to meet the handling needs of different PCB boards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] See Figures 1-4 As shown, a suction cup type PCB board handling device includes a support frame 1, a feeding and handling suction cup assembly 2, and a support platform 7. The feeding and handling suction cup assembly 2 is disposed above the support frame 1; a cylinder 201 is disposed above the support frame 1; a mounting block 202 is disposed above the support frame 1 and is fixedly mounted on the telescopic end of the cylinder 201; an air pump 203 is fixedly mounted on one side of the mounting block 202; multiple suction cup bodies 204 are fixedly mounted on the bottom of the mounting block 202; an air vent is provided between the air pump 203 and the top of the suction cup body 204; and a position sensor 10 is disposed on the mounting block 202.

[0024] Before the handling operation begins, the equipment is in an initial standby state. When an instruction to handle a PCB board is issued, the air pump 203 starts, drawing air from the suction cup body 204 through the air pipe to create a negative pressure environment inside the suction cup body 204. At the same time, the cylinder 201 starts working according to the control signal, and its extension end drives the mounting block 202 to move downward. Since the suction cup body 204 is fixed to the bottom of the mounting block 202, as the mounting block 202 descends, the suction cup body 204 gradually approaches the PCB board to be handled.

[0025] When the suction cup body 204 contacts the PCB board, it firmly adheres to the PCB board under negative pressure. At this time, the position sensor 10 functions, detecting the contact state between the suction cup body 204 and the PCB board, as well as whether the adhesion is complete, and feeding this information back to the control system. If the adhesion is not complete, the control system can adjust parameters such as the stroke of the cylinder 201 or the power of the air pump 203 based on the feedback signal from the position sensor 10 to ensure the reliability of the adhesion.

[0026] After successful adsorption, the telescopic end of cylinder 201 moves in the opposite direction, driving the mounting block 202 and the suction cup body 204 holding the PCB board upward, causing the PCB board to detach from its original position. Then, with the help of other transmission components such as slides that cooperate with the support frame 1, the feeding and transporting suction cup assembly 2 holding the PCB board is moved to the target position, such as the loading area of ​​the processing equipment or a designated buffer area, according to the preset transport path and direction.

[0027] Upon reaching the target location, the air pump 203 stops pumping air and releases it, restoring the internal pressure of the suction cup body 204 to equilibrium with the external pressure. This releases the suction from the PCB board, allowing it to be placed in the target position. This completes one PCB board handling process, and the equipment returns to standby mode, awaiting the next handling instruction. Throughout the process, the support platform 7 provides a stable foundation for all components, ensuring the smooth and reliable operation of the equipment. This minimizes the risk of physical damage such as collisions or scratches to the PCB board body 8 during handling, and avoids affecting subsequent processing, soldering, or inspection procedures due to inaccurate placement.

[0028] See Figure 1-3 The bottom of the support frame 1 is provided with a support platform 7, and suction cup transport slides 5 are symmetrically arranged on the support frame 1.

[0029] The support platform 7 at the bottom of the support frame 1 provides stable support for the entire device. During PCB board handling, the device needs to remain balanced and stable to ensure the suction cups can accurately pick up and move the PCB boards. The support platform 7 increases the contact area between the device and the ground or mounting surface, lowering the device's center of gravity and thus reducing swaying and vibration during operation. For example, when the device is rapidly moving heavy PCB boards, the stable support platform 7 prevents the device from tipping over, ensuring safe handling.

[0030] See Figure 4 A mounting bracket 9 is fixedly installed on the top of the cylinder 201, and the mounting bracket 9 is slidably connected to the suction cup transport slide 5.

[0031] The mounting bracket 9 is slidably connected to the suction cup transport slide 5, allowing the position of the mounting bracket 9 to be flexibly adjusted according to actual needs. This flexibility is particularly important when transporting PCBs of different sizes and shapes.

[0032] This allows the equipment to adapt to different production and handling requirements. By adjusting the position of the mounting bracket 9 on the suction cup handling slide 5, the number and layout of suction cups can be easily changed or increased to meet the handling needs of different PCB boards.

[0033] See Figure 4A first unloading suction cup 3 is slidably connected to the suction cup transport slide 5, and the first unloading suction cup 3 is located on the right side of the infeed suction cup assembly 2.

[0034] The first unloading suction cup 3 is slidably connected to the suction cup transport slide 5 and located to the right of the infeed suction cup assembly 2. This layout facilitates a continuous material handling process from infeeding and processing to unloading. During PCB production, the infeed suction cup assembly 2 can transport the PCB from the feeding area to the processing equipment, while the first unloading suction cup 3 can transport the PCB from the processing equipment to the unloading area after processing. By setting these two components on the same suction cup transport slide 5, the entire handling process is made more seamless, reducing the transfer time of the PCB between different transport devices and potential errors. For example, in an automated PCB production line, the coordinated work of these two suction cups ensures that the PCB flows efficiently and accurately according to the production process, improving production efficiency.

[0035] See Figure 4 A placement platform 6 is fixedly installed on the top of the support frame 1, and the feeding and conveying suction cup assembly 2 is set above the placement platform 6.

[0036] The placement platform 6 at the top of the support frame 1 provides a stable placement area for the PCB boards. During the feeding stage, the PCB boards can be neatly placed on the placement platform 6, facilitating pickup by the feeding and handling suction cup assembly 2. For example, during batch handling of PCB boards, operators can place multiple PCB boards orderly on the placement platform 6, and the feeding and handling suction cup assembly 2 can accurately pick up the PCB boards from this fixed position according to a preset program or instruction, improving the accuracy and efficiency of pickup.

[0037] See Figure 4 A Y-direction unloading suction cup 4 is provided on the right side of the first unloading and transporting suction cup 3, and the PCB board body 8 is located at the bottom of the suction cup body 204.

[0038] The cooperation between the first unloading suction cup 3 and the unloading Y-direction suction cup 4 enables relay-style unloading and transport. After the PCB board is processed, the first unloading suction cup 3 can first remove the PCB board from the processing equipment and then pass it to the unloading Y-direction suction cup 4 for transport in the Y direction, which is typically a specific direction on the production line, such as transporting the PCB board from one processing area to the unloading buffer area. This division of labor and cooperation makes the unloading process more efficient, reducing the time spent by a single suction cup frequently adjusting its position in multiple directions, thereby speeding up the entire unloading process and improving production efficiency. For example, in a high-speed PCB production line, this relay transport mechanism can ensure that the PCB board flows quickly and orderly during the unloading process, adapting to the needs of high-volume production.

[0039] Working Principle: Before the handling operation begins, the equipment is in an initial standby state. When an instruction to handle a PCB board is issued, the air pump 203 starts, drawing air from the suction cup body 204 through the air pipe, creating a negative pressure environment inside the suction cup body 204. At the same time, the cylinder 201 starts working according to the control signal, and its extension end drives the mounting block 202 to move downward. Since the suction cup body 204 is fixed to the bottom of the mounting block 202, as the mounting block 202 descends, the suction cup body 204 gradually approaches the PCB board to be handled.

[0040] When the suction cup body 204 contacts the PCB board, it firmly adheres to the PCB board under negative pressure. At this time, the position sensor 10 functions, detecting the contact state between the suction cup body 204 and the PCB board, as well as whether the adhesion is complete, and feeding this information back to the control system. If the adhesion is not complete, the control system can adjust parameters such as the stroke of the cylinder 201 or the power of the air pump 203 based on the feedback signal from the position sensor 10 to ensure the reliability of the adhesion.

[0041] After successful adsorption, the telescopic end of cylinder 201 moves in the opposite direction, driving the mounting block 202 and the suction cup body 204 holding the PCB board upward, causing the PCB board to detach from its original position. Then, with the help of other transmission components such as slides that cooperate with the support frame 1, the feeding and transporting suction cup assembly 2 holding the PCB board is moved to the target position, such as the loading area of ​​the processing equipment or a designated buffer area, according to the preset transport path and direction.

[0042] Upon reaching the target location, the air pump 203 stops pumping air and releases it, restoring the internal pressure of the suction cup body 204 to equilibrium with the external pressure. This releases the suction from the PCB board, allowing it to be placed in the target position. This completes one PCB board handling process, and the equipment returns to standby mode, awaiting the next handling instruction. Throughout the process, the support platform 7 provides a stable foundation for all components, ensuring the smooth and reliable operation of the equipment. This minimizes the risk of physical damage such as collisions or scratches to the PCB board body 8 during handling, and avoids affecting subsequent processing, soldering, or inspection procedures due to inaccurate placement.
