Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board processing technology, specifically a PCB board separation fixture with shock absorption effect. Background Technology
[0002] PCB depaneling fixtures are tools specifically designed for dividing printed circuit boards (PCBs) during electronic manufacturing. The main purpose of these fixtures is to ensure high precision and stability when dividing large PCBs into smaller ones, thereby preventing damage to components on the circuit board and ensuring smooth cut edges. To reduce manufacturing costs, existing PCB depaneling fixtures use a high-strength aluminum alloy frame as the basic structure, equipped with sliding positioning pins and replaceable clamping modules. By adjusting three main parameters—track spacing (50-250mm), clamping force (0.5-2.5kg), and support height (3-15mm)—one fixture can accommodate products of up to six different sizes. The fixture also features a quick-locking mechanism and a foolproof positioning device to ensure secure product fixation and easy operation.
[0003] Existing PCB depaneling fixtures typically only clamp PCBs in a single direction or at a single point, lacking overall support and fixation for the board surface. This leads to uneven stress or lack of effective support during cutting or depaneling, making the PCB prone to bending, deformation, or even breakage. This problem is particularly pronounced when processing thin or multilayer boards, severely impacting depaneling accuracy and product quality. Furthermore, traditional fixtures are difficult to adjust to different PCB thicknesses, shapes, and materials, further exacerbating instability during processing. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0024] The present invention will be further described below with reference to the embodiments.
[0025] Example: A PCB depaneling fixture with shock absorption effect, such as... Figures 1-5 As shown, the machine includes a processing table 1. The surface of the processing table 1 is provided with a support assembly 2. The support assembly 2 includes two first moving rods 21 and a first placement plate 25. The first moving rods 21 are movably connected to the left and right sides of the inner cavity of the processing table 1. One of the first moving rods 21 has an external thread on its surface. Mounting seats 26 are fixedly connected to both sides of the top of the first placement plate 25. Spring damping rods 27 are connected to the surface of the mounting seats 26. One end of the spring damping rods 27 is connected to a fixed seat 28.
[0026] like Figures 2-5 As shown, a second placement plate 29 is fixedly connected to the top of the fixed base 28. The second placement plate 29 is used to support and dampen the PCB board during the cutting process. A motor 22 is fixedly connected to the rear side of the processing table 1. The output shaft of the motor 22 is fixedly connected to the rear end of the first moving rod 21. A moving plate 23 is movably connected to the surface of the first moving rod 21. The area of the moving plate 23 in contact with the first moving rod 21 is provided with a matching internal thread. The bottom of the moving plate 23 is slidably connected to the bottom of the inner cavity of the processing table 1. Several connecting rods 24 are fixedly connected to the top of the moving plate 23. The processing table 1 has through cavities that are compatible with the connecting rods 24. The top of the connecting rod 24 is fixedly connected to the bottom of the first placement plate 25. Guide frames 210 are fixedly connected to both sides of the bottom of the second placement plate 29. Positioning plates 212 are fixedly connected to both sides of the top of the first placement plate 25. A round rod 213 is rotatably connected to the surface of the positioning plate 212. Two symmetrically arranged push plates 214 are fixedly connected to the surface of the round rod 213. A long rod 211 is connected to one side of the push plate 214, and the surface of the long rod 211 is movably connected to the inner side of the guide frame 210. Telescopic rods 215 are fixedly connected to the left and right sides of the top of the first placement plate 25. The output end of the telescopic rod 215 is fixedly connected to the bottom of the second placement plate 29.
[0027] like Figures 3-5As shown, welding seats 216 are fixedly connected to both the front and rear sides of the top of the processing table 1. Several second moving rods 217 are installed through the inner cavity of the welding seat 216. The size of the inner cavity of the welding seat 216 can be changed according to actual needs, such as increasing or decreasing the volume of the inner cavity of the welding seat 216 to suit PCB boards of different sizes. A pressure plate 218 is fixedly connected to the bottom end of the second moving rod 217, and the surface of the pressure plate 218 is slidably connected to the inner cavity of the welding seat 216. A spring 219 is connected to the top of the pressure plate 218, and the top end of the spring 219 is connected to the inner cavity of the welding seat 216. A moving device 3 is installed on the rear side of the top of the processing table 1. An L-shaped plate 4 is fixedly connected to the movable part of the moving device 3. A cylinder 41 is fixedly connected to the top of the L-shaped plate 4. A cutting blade 42 is fixedly connected to the output end of the cylinder 41. Several cutting grooves 43 that are adapted to the cutting blade 42 are fixedly connected to the processing table 1.
[0028] Specifically, the user manually pulls the second moving rod 217 upwards, causing the pressure plate 218 to rise synchronously. During this process, the spring 219 is compressed. After release, the spring 219 automatically resets due to its elasticity, thus adapting to the clamping requirements of PCB boards of different thicknesses. After clamping and positioning are completed, the motor 22 is started, driving the first moving rod 21 to rotate, which in turn moves the moving plate 23 along the guide rail. The moving plate 23, through the connecting rod 24, moves the second placement plate 29 synchronously, achieving accurate positioning of the PCB board. Subsequently, the cylinder 41 is activated, pushing the cutting blade 42 downwards. The cutting blade 42 cuts the PCB board along the direction of the groove 43.
[0029] During the cutting process, the second placement plate 29 first provides support for the bottom of the PCB board. Part of the impact force generated during the cutting process is transmitted to the spring damping rod 27 through the second placement plate 29, which is buffered and absorbed. The other part of the force pushes the second placement plate 29 to move the guide frame 210. The guide frame 210 drives the long rod 211 to move synchronously. The long rod 211 pushes the push plate 214 to move, thereby further guiding the second placement plate 29 to generate elastic displacement in the vertical direction. This effectively buffers and absorbs the vibration and pressure generated during the cutting process, preventing the PCB board from deforming or breaking due to excessive force.
[0030] After cutting, the second placement plate 29 can still provide support for the cut PCB board, making it easy for users to safely and conveniently remove the finished product. This improves the safety and convenience of operation, and realizes the organic combination of clamping, cutting and support functions, effectively improving the stability and yield of the PCB separation process.
[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
