Description
Technical Field
[0001] This utility model relates to the field of PCB technology, specifically a novel suction cup for a board take-up machine after etching lines. Background Technology
[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection.
[0003] Since the beginning of the 21st century, electronic products have continuously moved towards greater portability, multifunctionality, and intelligence. As the "mother of electronic products," the PCB board must also evolve towards miniaturization and multifunctionality. Miniaturization and multifunctionality of PCB boards mean reducing the board area while increasing functionality. Current technology primarily aims to achieve this by increasing the number of layers, but this has also led to a gradual increase in PCB weight. Therefore, intelligent handling technology for PCB boards requires stronger adhesion and a more stable handling process to address the impact of increased PCB weight.
[0004] In the PCB etching process, specific chemicals are used to remove the exposed copper after development, thereby creating circuit patterns. Due to the complexity of the circuitry, the surface of the PCB often exhibits an uneven texture. Moreover, PCB manufacturing is often done in large-scale production of tens of thousands of units. Due to considerations of production efficiency, some etched PCBs are not properly cleaned, resulting in the retention of some etching solution and other impurities. This undoubtedly increases the difficulty of handling the PCBs and brings many inconveniences and challenges to related operations.
[0005] The existing technology has the following problems:
[0006] Existing PCB board handling machines generally use corrugated suction cups for vacuum adsorption. If the PCB surface is not thoroughly cleaned after etching, residue on the PCB can affect the adsorption effect of the vacuum suction cups, easily causing the PCB to detach. Furthermore, most existing adjustable PCB board gripping devices adjust the forward and backward movement of the suction cup frame without changing the number of suction cups. This method relies heavily on manual judgment to adjust the distance between the suction cup frames, resulting in low adjustment efficiency. Moreover, the increased weight due to changes in the number of layers in multilayer boards means that the current two-row suction cup assembly is insufficient to reliably complete the transport task. Utility Model Content
[0007] The purpose of this invention is to provide a novel suction cup for a plate take-up machine after etching lines, so as to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel suction cup for a plate retraction machine after etching line, comprising a horizontal suspension, wherein the horizontal suspension is movably mounted on the top of two suspension translation modules, and each of the two suspension translation modules is rotatably mounted with a screw, the two screws respectively passing through both ends of the horizontal suspension and threadedly connected to the horizontal suspension, and each of the two suspension translation modules is fixedly mounted with a servo motor, the output end of each servo motor being connected to a screw via a transmission box, a telescopic device being slidably mounted on the bottom of the horizontal suspension, a steering device being fixedly connected to the bottom of the telescopic device, a pitch-changing module being rotatably mounted on the bottom of the steering device, and multiple support modules being slidably mounted on the bottom of the pitch-changing module, each support module having multiple suction cup bodies fixedly connected to its bottom, and a vision module being fixedly mounted on the bottom of one support module, the vision module being located inside the multiple suction cup bodies.
[0009] By activating the servo motor, the transmission box drives the screw to rotate. The screw passes through and is threadedly connected to the horizontal suspension, allowing the horizontal suspension to move back and forth. A vision module precisely positions the PCB board. A variable-pitch module allows the support module to separate or reassemble, changing the suction cup's adsorption area. A steering device rotates the variable-pitch module by a certain angle, simultaneously rotating the suction cup itself. A telescopic device then lowers the suction cup, adsorbing PCB boards of varying shapes and sizes on the conveyor mechanism, thus achieving intelligent PCB board adsorption. It can pick up and eliminate the need for PCB board alignment on the conveyor belt. By delivering outside air to the inside of the suction cup body through an air tube, the suction cup body blows the air downward to form an airflow, cleaning the corresponding adsorption positions on the PCB board, removing residues from the board surface, and improving the adsorption effect of the suction cup body. By extracting air from the suction cup body, a negative pressure is generated inside the suction cup body to adsorb and fix the PCB board. At the same time, the suction cup body is a hollow vacuum suction cup. Compared with ordinary vacuum suction cups, the internal space of the hollow vacuum suction cup is smaller, the negative pressure inside the suction cup body is formed faster, and the working efficiency is higher.
[0010] Preferably, a guide rail connecting device is fixedly installed on the top of the telescopic device, and the guide rail connecting device is slidably installed between the telescopic device and the horizontal suspension. The telescopic device and the horizontal suspension are slidably connected through the guide rail connecting device. The guide rail connecting device can drive the telescopic device to move left and right along the horizontal suspension.
[0011] Preferably, an air pump is fixedly installed on the top of the variable pitch module, and the air pump is located on one side of the steering device. An air pipe is fixedly installed on the top of each support module, and the air pipe is connected to the suction cup body. Multiple air pipes are fixedly connected to the air pump. The air pump can easily deliver outside air into the suction cup body, and at the same time, it can easily extract air from the suction cup body. The air pipes can connect and fix the air pump to the suction cup body.
[0012] Preferably, each suspension translation module has two support frames fixedly installed at its bottom, and each support frame has a fixed base fixedly connected to its bottom. The bottom of the pitch control module has multiple module tracks fixedly installed, and the multiple support modules are slidably connected to the multiple module tracks respectively. The support frames support and fix the suspension translation module, the fixed bases facilitate the installation and fixing of the support frames in a suitable position, and the module tracks allow the support modules to slide left and right easily.
[0013] Preferably, a control module is fixedly installed between the telescopic devices of the steering device. Each suspension translation module has two bearings and supports fixedly installed on its top. Each screw passes through two bearings and supports and is rotatably connected to them. The control module allows for operation of the steering device, while the bearings and supports support the screws and facilitate their rotation.
[0014] Preferably, each transmission box contains two gear disks, one end of each screw extends into the transmission box and is fixedly connected to the shaft of one gear disk, and the output end of each servo motor extends into the transmission box and is fixedly mounted to the shaft of the other gear disk. Through the meshing of the gear disks, the output end of the servo motor can drive the screw to rotate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model fully utilizes the positive pressure mode of the air pump to deliver outside air to the inside of the suction cup body through the air tube. The suction cup body blows the air downward to form an airflow, cleaning the corresponding adsorption positions on the PCB board, removing residues from the board surface, and improving the adsorption effect of the suction cup body. Through the negative pressure mode of the air pump, the air inside the suction cup body can be extracted, creating a negative pressure inside the suction cup body to adsorb and fix the PCB board. At the same time, the suction cup body is a hollow vacuum suction cup. Compared with ordinary vacuum suction cups, the hollow vacuum suction cup has less internal space, and the negative pressure inside the suction cup body is formed faster, resulting in higher working efficiency.
[0017] 2. This utility model utilizes image capture technology to accurately locate the placement position of the PCB board through a vision module. The variable pitch module and module track allow the support module to be separated or moved together, changing the adsorption area of the suction cup body. By controlling the steering device through the control module, the variable pitch module can be rotated at a certain angle, which simultaneously drives the suction cup body to rotate at a certain angle. The telescopic device drives the suction cup body to descend, adsorbing PCB boards in different situations on the conveyor mechanism, realizing intelligent PCB board adsorption and eliminating the step of aligning the PCB board on the conveyor belt.

The output end of each servo motor 16 extends into the interior of a transmission box 18 and is fixedly installed to the shaft of the other gear disk 20.
[0030] The working principle of the suction cup of the new etching line retractor based on the embodiment is as follows: by installing and fixing the support frame 10 in a suitable position, the servo motor 16 drives a gear disk 20 to rotate.
