Description

Technical Field

[0001] This invention relates to the field of PCB electroplating technology, and in particular to a semi-automatic loading and unloading device for a gantry vertical electroplating line. Background Technology

[0002] Electronic devices are devices made in vacuum, gas, or solid environments by utilizing and controlling the laws of electron motion. They are classified into vacuum electronic devices, gas-filled tube devices, and solid-state electronic devices. In analog circuits, they perform functions such as rectification, amplification, modulation, oscillation, frequency conversion, phase-locked loop, control, and correlation. Most electronic devices require PCB circuit boards to support electrical components. During the manufacturing process, PCB circuit boards undergo electroplating, which is usually performed using electroplating fixtures.

[0003] Currently available semi-automatic loading and unloading devices for gantry vertical electroplating lines have several drawbacks. The process of placing PCB boards is cumbersome and lacks automation, often requiring multiple people to complete the online operation of the same product. This increases labor costs and reduces overall efficiency. Furthermore, the fixed positions of the mounting claws make it difficult to adjust them flexibly according to different hole structures on the PCB board, resulting in poor PCB board fixation and limited adjustability, failing to meet diverse production needs. In addition, the disassembly and maintenance of the fixing claw plates are complex and time-consuming, significantly impacting maintenance efficiency and consequently affecting the continuity and stability of production. Summary of the Invention

[0007] Furthermore, a set of guide grooves are provided on the transfer seat, and a set of guide blocks are fixedly installed on the inner end of the moving seat, and the guide blocks at the inner end of the moving seat are slidably installed on the guide grooves of the transfer seat.

[0008] Furthermore, a set of fixing plates is fixedly installed on the outer end of the movable seat. The fixing plates have sliding holes, and a connecting rod is fixedly installed on the bottom of the limiting block. The connecting rod at the bottom of the limiting block is slidably installed on the sliding hole of the fixing plate.

[0009] Furthermore, a set of mounting slots is provided at the bottom of the movable base, and a connecting slot is fixedly connected to the top of the fixed claw plate, and the connecting slot at the top of the fixed claw plate is inserted into the mounting slot at the bottom of the movable base.

[0010] Furthermore, the movable claw plate is provided with a set of threaded holes, and a set of threaded rods are threadedly installed on the threaded holes of the movable claw plate. The inner end of the threaded rod is an external connecting rod, and a set of reset elastic elements are sleeved on the external connecting rod. The fixed claw plate is provided with a connecting groove, and the external connecting rod is inserted into the connecting groove of the fixed claw plate.

[0011] Furthermore, a set of support plates is fixedly installed at the rear end of the movable seat. The support plates have sliding holes, and a sliding rod is fixedly installed at the outer end of the positioning rod. The sliding rod at the outer end of the positioning rod is slidably installed on the sliding hole of the support plate.

[0012] Furthermore, a first fixing post is fixed to the bottom of the fixed claw plate, a limit rod is fixedly installed at the upper end of the first fixing post, a second fixing post is fixed to the bottom of the movable claw plate, and the PCB board is placed between the first fixing post and the second fixing post.

[0013] Furthermore, a set of first elastic elements is sleeved on the slide rod at the outer end of the positioning rod, and the bottom of the first elastic elements is in contact with the top surface of the support plate on the movable seat.

[0014] Furthermore, a set of guide holes are respectively opened at both ends of the mounting base, and a set of guide rods are respectively fixedly installed at both ends of the transfer base, and the guide rods at both ends of the transfer base are slidably installed on the guide holes at both ends of the mounting base.

[0015] This invention provides a semi-automatic loading and unloading device for a gantry vertical electroplating line, which has the following beneficial effects: In this invention, a threaded rod is installed on the movable claw plate, and an external rod is sleeved with a reset elastic element. A pneumatic telescopic rod drives the roller to move, causing the movable claw plate to rotate, facilitating the placement of the PCB board. After reset, the first and second fixed posts are quickly fixed, simplifying operation and improving automation. One person can complete the online operation of the same product, improving work efficiency. The outer end of the positioning rod is slidably installed on the support plate, and the moving seat guide block is slidably installed on the transfer seat guide groove. After movement, the positioning rod is inserted into the positioning hole under the action of the first elastic element, which facilitates the adjustment of the mounting claw position according to the hole structure of the PCB board, improving the fixing effect and adjustability. The bottom connecting rod of the limiting block is slidably installed on the fixed plate. Pulling the limiting block outward will insert the fixed claw plate into the mounting groove. After it is in place, the limiting block is inserted into the limiting groove under the action of the second elastic element, which facilitates the quick disassembly and maintenance of the fixed claw plate, improving maintenance efficiency.

[0016] In addition, a set of threaded rods is threaded onto the threaded holes of the movable claw plate, and a set of reset elastic elements is sleeved on the external rod to facilitate the installation and removal of the reset elastic elements. The pneumatic telescopic rod drives the roller to move inward to press the top of the movable claw plate and make it rotate on the fixed claw plate, so that the first fixed post on the fixed claw plate does not contact the second fixed post on the movable claw plate. This makes it easier for workers to place the PCB board between the first and second fixed posts. After the pneumatic telescopic rod drives the roller to move outward and reset, the first and second fixed posts quickly fix the PCB board under the action of the reset elastic elements. This simplifies the operation of the device, improves the automation level of the equipment, and only one person is needed to complete the online operation of the same product, thus improving work efficiency.

[0017] Furthermore, the positioning rod is slidably mounted on the sliding hole of the support plate by the slide rod at the outer end. Pulling the positioning rod outward causes the guide block at the inner end of the moving seat to slide onto the guide groove of the transfer seat. After moving the moving seat to the desired position, the positioning rod is released. Under the action of the first elastic element on the slide rod, the positioning rod is inserted into the positioning hole at the bottom of the transfer seat. This allows the moving seat of the device and its mounting claws to be adjusted left and right according to the different hole structures on the PCB board, thereby improving the fixing effect of the device and giving the device better adjustability.

[0018] Furthermore, by sliding the connecting rod at the bottom of the limiting block onto the sliding hole of the fixed plate, pulling the limiting block outwards allows the connecting groove at the top of the fixed claw plate to be inserted into the mounting groove at the bottom of the movable seat. After the fixed claw plate moves to the fixed position, the limiting block is released. Under the action of the second elastic element on the connecting rod, the limiting block at the bottom of the movable seat is inserted into the limiting groove on the fixed claw plate. This makes the fixed claw plate of this device easy to disassemble and maintain quickly, improving the device's maintenance efficiency. Attached Figure Description
