Description

Technical Field

[0001] This application relates to the field of transfer rack technology, and in particular to a PCB transfer rack. Background Technology

[0002] In the electronics manufacturing industry, PCBs (printed circuit boards) are core components of electronic devices, and their quality directly determines the performance and reliability of the final product. PCBs integrate a large number of precision electronic components (such as chips, resistors, and capacitors), which are extremely sensitive to static electricity—even a small amount of static electricity (usually a few volts to tens of volts) can break down the internal insulation layer of the component, burn out the semiconductor structure, or change the component's electrical performance parameters, leading to product failure and significant production losses.

[0003] As electronic devices become smaller and more precise, the integration of components on PCBs is increasing, placing more stringent demands on electrostatic discharge (ESD) protection, stability, and compatibility during transport. The market urgently needs a specialized transport device that can simultaneously achieve efficient movement, secure fixation, precise ESD protection, and flexible adaptation to various PCB specifications. This will address the pain points of traditional transport methods and ensure the quality stability of PCBs throughout the production process. Summary of the Invention

[0004] Technical problems to be solved

[0005] The purpose of this application is to provide a PCB transfer rack that meets the dedicated transfer needs of PCBs of various specifications and solves the problems mentioned in the background art.

[0006] The PCB transfer rack provided in this application adopts the following technical solution: a PCB transfer rack includes a support assembly, a placement assembly and a moving assembly. The support assembly includes two outer frames and four cross columns. The bottom of each outer frame is fixedly connected to a fixing plate. The two ends of the four cross columns are respectively installed in the top of the two outer frames and in the inner wall of the two fixing plates.

[0007] The placement assembly includes an anti-static tray with a placement slot for placing PCB boards on its outer surface. Two connecting brackets are fixedly connected to both the upper and lower ends of the anti-static tray. A rotating shaft is installed on the inner wall of each connecting bracket, and a rotatable pressure locking plate is installed on the outer surface of each rotating shaft. Two elastic pressure strips are installed at both the upper and lower ends of the anti-static tray, and the four elastic pressure strips are located below the four pressure locking plates.

[0008] By adopting the above technical solution, the outer frame and crossbars in the bracket assembly form a stable support structure, providing a reliable installation foundation for the placement and moving components, and ensuring the stability of the overall structure during transportation. The anti-static tray in the placement component provides dedicated placement space for PCB boards through the placement slot. With the rotatable pressure locking plate and elastic pressure strip, the position of the anti-static tray can be flexibly adjusted, thereby adapting to PCB boards of different sizes and meeting the transportation needs of PCB boards of different sizes. At the same time, the anti-static tray can serve as a key node for static electricity conduction, providing a path for subsequent static electricity discharge.

[0009] Preferably, each of the horizontal columns is equipped with a first connecting bolt at both ends, and the horizontal column is installed between the outer frame and the fixing plate by the first connecting bolt.

[0010] By adopting the above technical solution, the first connecting bolt enables the detachable connection between the cross column and the outer frame and the fixed plate, which facilitates the assembly, disassembly and maintenance of the device, solves the problem of the fixed structure and difficulty in maintenance of traditional transfer tools, and improves the flexibility and adaptability of the equipment.

[0011] Preferably, marking strips are installed on both sides of the antistatic tray.

[0012] By adopting the above technical solution, the marking strip can be used to mark the specifications, model or status information of the PCB board in the placement slot, which makes it easier for operators to quickly identify, reduce misoperation during the picking and placing process, improve transfer efficiency, and avoid production process delays caused by information confusion.

[0013] Preferably, each of the shafts is threaded with a nut at its end.

[0014] By adopting the above technical solution, the nut can lock the position of the rotating shaft in the connecting frame, preventing the lower locking plate from loosening due to vibration during transportation, ensuring the clamping stability of the PCB board, and avoiding the problem of the board slipping off due to the loosening of traditional fixing structures.

[0015] Preferably, a handle is fixedly connected to the top of each of the pressing lock plates.

[0016] By adopting the above technical solution, the handle provides a convenient force application point for the rotation operation of the pressure locking plate. The operator can easily adjust the angle of the pressure locking plate through the handle, and can install the anti-static tray in different positions, thereby enabling the transfer of PCB boards of different thicknesses.

[0017] Preferably, each of the elastic pressure strips has two second connecting bolts installed at one end, and the elastic pressure strip is installed on the outer surface of the second connecting bolts through the second connecting bolts.

[0018] By adopting the above technical solution, the second connecting bolt enables a detachable connection between the elastic pressure strip and the anti-static tray, which facilitates the replacement of new elastic pressure strips as needed, ensures moderate clamping force, avoids board shaking caused by excessive looseness, and prevents board damage caused by excessive tightness, thereby improving the equipment's adaptability to PCB boards of various specifications.

[0019] Preferably, the moving component includes casters mounted at the bottom of two outer frames, each caster having a brake pad installed inside.

[0020] By adopting the above technical solutions, the casters in the mobile components enable the device to move flexibly, adapt to the transfer needs of different scenarios such as workshops and warehouses, reduce manual handling costs, and the brake pads can lock the casters when loading and unloading PCB boards to prevent the device from sliding accidentally, thus solving the problems of poor mobility and low operational safety of traditional transfer tools.

[0021] Preferably, an electrostatic chain is installed on the outer surface of each of the fixing plates.

[0022] By adopting the above technical solution, the electrostatic chain connects the fixed plate to the ground, forming a complete electrostatic discharge channel. This allows the static electricity conducted from the PCB board to the electrostatic chain through the anti-static tray and support assembly to be smoothly conducted to the ground, effectively eliminating the harm of static electricity to the precision electronic components on the PCB board. This solves the problem of lack of electrostatic protection in traditional transportation methods and ensures the quality stability of the PCB board.

[0023] Beneficial effects

[0024] This PCB transfer rack provides a reliable load-bearing foundation for the entire device through a stable support structure consisting of an outer frame and crossbars in the bracket assembly. The detachable connection design, achieved with the first connecting bolt, enhances the flexibility of assembly and maintenance. The anti-static tray in the placement assembly serves as a key node for static electricity conduction, providing dedicated space for PCB boards through placement slots. An adjustable locking structure composed of a connecting frame, rotating shaft, and lower locking plate, combined with a convenient handle, allows for flexible adaptation to PCB boards of different sizes. The combination of elastic pressure strips and the second connecting bolts ensures moderate clamping force to prevent damage. Marking strips reduce operational errors through information labeling, while nuts ensure clamping stability during transfer. The omnidirectional wheels in the moving assembly enable flexible movement of the device, brake pads ensure secure fixing during loading and unloading, and an anti-static chain constructs a complete static electricity release channel, conducting static electricity from the PCB boards to the ground. This effectively solves the problems of poor adaptability, significant static electricity hazards, and inconvenient operation in traditional transfer methods, meeting the needs for efficient and safe transfer of PCB boards of various specifications.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0033] Example 1: A PCB transfer frame, referring to Figure 1 , Figure 2 and Figure 3 The system includes a support assembly 1, a placement assembly 2, and a moving assembly 3. The support assembly 1 includes two outer frames 101 and four crossbars 103. Each outer frame 101 has a fixed plate 102 fixedly connected to its bottom. The two ends of the four crossbars 103 are respectively installed in the top of the two outer frames 101 and in the inner wall of the two fixed plates 102. Each end of the crossbar 103 is equipped with a first connecting bolt 104. The crossbars 103 are installed between the outer frames 101 and the fixed plates 102 by the first connecting bolts 104. The first connecting bolts 104 enable the crossbars 103 to be detachably connected to the outer frames 101 and the fixed plates 102. This facilitates the assembly, disassembly, and maintenance of the device, solving the problems of fixed structure and difficulty in maintenance of traditional transfer tools, and improving the flexibility and adaptability of the equipment. The moving component 3 includes casters 301 installed at the bottom of the two outer frames 101. Each caster 301 is equipped with a brake pad 302. The casters 301 in the moving component 3 enable the device to move flexibly and adapt to the transfer needs of different scenarios such as workshops and warehouses, reducing the cost of manual handling. The brake pad 302 can lock the casters 301 when loading and unloading PCB boards to prevent the device from sliding accidentally, solving the problems of poor movement stability and low operation safety of traditional transfer tools.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The placement component 2 includes an anti-static tray 201. The outer surface of the anti-static tray 201 has a placement slot 202 for placing the PCB board. Two connecting brackets 204 are fixedly connected to both the upper and lower ends of the anti-static tray 201. A rotating shaft 205 is installed on the inner wall of each connecting bracket 204. A rotatable downward locking plate 206 is installed on the outer surface of each rotating shaft 205. Two elastic pressure strips 209 are installed at both the upper and lower ends of the anti-static tray 201. The four elastic pressure strips 209 are located below the four downward locking plates 206. The placement component 2 serves as a direct support and fixation point for the PCB board. The core component of the PCB board is designed with compatibility and safety in mind. The anti-static tray 201, made of anti-static material, not only provides stable support for the entire placement structure but also acts as a key carrier for static electricity conduction, quickly dissipating static electricity from the PCB board and preventing damage to electronic components from static buildup. The placement groove 202 on the outer surface of the anti-static tray 201 provides dedicated space for the PCB board, initially limiting its position and preventing lateral shifting during transport. Compared to traditional flat placement, this design offers greater stability. Two connecting brackets 204, fixedly connected to the upper and lower ends of the disc 201, provide a stable mounting base for the rotating shaft 205, ensuring that the rotating shaft 205 is not easily loosened under force. The rotating shaft 205, installed on the inner wall of the connecting bracket 204, provides the axis for the rotation of the lower locking plate 206, allowing the lower locking plate 206 to flexibly adjust its angle to adapt to PCB boards of different thicknesses. The rotatable lower locking plate 206 installed on the outer surface of each rotating shaft 205 can cooperate with the elastic pressure strip 209 below during rotation to form an upper and lower clamping of the PCB board placed in the placement slot 202. By adjusting the lower... The downward pressure of the locking plate 206 can adapt to the fixing requirements of PCB boards of different thicknesses, solving the problems of single size and poor adaptability of traditional fixing structures. The four elastic pressure strips 209 installed at the upper and lower ends of the anti-static tray 201 correspond to the positions of the four locking plates 206. They are made of elastic material and can buffer the clamping force through their own elasticity when the locking plates 206 are pressed down, avoiding rigid contact that could cause indentation or damage to the placement slot 202. At the same time, they enhance the tightness of the clamping and prevent the PCB board from shaking longitudinally due to bumps during transportation, further improving the reliability of the fixing.

[0035] Example 2: A PCB transfer frame, referring to Figure 3 , Figure 4 and Figure 5Based on the same concept as Embodiment 1 above, this embodiment proposes that both sides of the antistatic tray 201 are equipped with marking strips 203. The marking strips 203 can be used to mark the specifications, models or status information of the PCB boards in the placement slot 202, which is convenient for operators to quickly identify, reduce misoperation during the picking and placing process, improve transfer efficiency, and avoid production process delays caused by information confusion. Each rotating shaft 205 is threaded with a nut 208 at its end. The nut 208 can lock the position of the rotating shaft 205 in the connecting frame 204 to prevent the pressure locking plate 206 from loosening due to vibration during the transfer process, ensuring the clamping stability of the PCB board and avoiding the problem of board slippage caused by the loosening of traditional fixing structures. Each pressure locking plate 206 is fixedly connected to a handle 207 at its top. The handle 207 provides a convenient force application point for the rotation operation of the pressure locking plate 206. The operator can easily adjust the angle of the pressure locking plate 206 through the handle 207, which can install the antistatic tray 201 in different positions, thereby realizing the transfer of PCB boards of different thicknesses.

[0036] Reference Figure 3 , Figure 4 and Figure 5 Each elastic pressure bar 209 has two second connecting bolts 210 installed at one end. The elastic pressure bar 209 is installed on the outer surface of the second connecting bolt 210 through the second connecting bolt 210. The second connecting bolt 210 realizes the detachable connection between the elastic pressure bar 209 and the anti-static tray 201, which facilitates the replacement of new elastic pressure bars 209 as needed, ensures that the clamping force is moderate, avoids board shaking caused by being too loose, and prevents board damage caused by being too tight, and improves the adaptability of the equipment to PCB boards of various specifications. Each fixed plate 102 has an anti-static chain 4 installed on its outer surface. The anti-static chain 4 connects the fixed plate 102 to the ground, forming a complete anti-static discharge channel, so that the static electricity conducted by the PCB board to the anti-static chain 4 through the anti-static tray 201 and the bracket assembly 1 can be smoothly conducted to the ground, effectively eliminating the harm of static electricity to the precision electronic components on the PCB board, solving the problem of lack of static protection in traditional transfer methods, and ensuring the quality stability of the PCB board.

[0037] The implementation principle of this application embodiment is as follows: First, push the overall frame of the support assembly 1, which consists of an outer frame 101, a fixed plate 102, and a cross column 103. Utilize the rolling characteristics of the casters 301 in the moving assembly 3 to move the equipment to the PCB storage location. Upon reaching the target location, press the brake pad 302 to lock the casters 301, ensuring the transfer frame is stably stationary. Then, according to the specifications of the PCB to be transferred, rotate the lower locking plate 206 via the handle 207. The lower locking plate 206 rotates around the pivot 205 within the connecting frame 204, pressing down onto the surface of the elastic pressure strip 209, thus positioning and installing the anti-static tray 201. Afterward, the positions of multiple anti-static trays 201 can be adjusted according to the specifications of the PCB, thereby meeting the transfer requirements of PCBs of different specifications. Finally, tighten the nut 208 to lock the pivot 205. Position 05 prevents the lower locking plate 206 from loosening during transport. After prolonged use, the elastic pressure strip 209 can be removed and replaced via the second connecting bolt 210. During the entire operation and transport process, the static electricity generated on the PCB board surface is conducted to the outer frame 101 and fixing plate 102 of the support assembly 1 through contact with the anti-static tray 201, and then released to the ground via the anti-static chain 4, preventing static electricity from damaging electronic components. When it is necessary to transfer to the next stage, the brake pad 302 is released, and the support assembly 1 can be moved again via the caster wheel 301. The presence of the first connecting bolt 104 ensures that the connection between the cross column 103 and the outer frame 101 and fixing plate 102 is stable, ensuring the load-bearing safety of the overall structure during movement, thereby realizing a safe and efficient whole process of PCB board from picking up and placing to transport and storage.
