Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a multifunctional electronic experimental workbench. Background Technology

[0002] As core equipment for electronic engineering research, teaching, and maintenance, the design rationality of electronic experimental workbenches directly affects experimental efficiency and equipment safety. In teaching laboratories, students need to complete circuit board fabrication at the soldering station before moving it to the testing area to connect the oscilloscope. This process is not only time-consuming, but also prone to damaging precision solder joints during movement, and residual solder slag can contaminate the interfaces of testing instruments. Currently, mainstream experimental workbenches on the market have the following structural defects:

[0003] 1. Low space utilization: Testing instruments, welding equipment, tools, etc. need to be placed separately, occupying a large amount of table space, and small laboratories cannot accommodate multiple workbenches;

[0004] 2. Exposed instruments are susceptible to physical damage (such as drops or welding slag contamination), and precision modules lack protection, increasing maintenance costs.

[0005] 3. Fragmented operation process: The welding area and the testing area are physically separated, requiring users to repeatedly move the workpiece, which leads to operation interruption and reduced efficiency; moreover, the fixed fixture cannot be adapted to PCB boards or components of different sizes.

[0006] Therefore, a multifunctional electronic experimental workbench is proposed to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides a multifunctional electronic experimental workbench. The utility model provides the following technical solution, including: a testing unit, a workbench body, a display set on the desktop of the workbench body, and adjustable feet set around the bottom of the workbench body.

[0008] The workbench body has an opening on its desktop, and a storage cavity and a base plate are located below the opening. A mounting bracket is located inside the storage cavity. One side of the mounting bracket is connected to the back of the workbench body, and the other side has a flipping mechanism. The flipping mechanism is connected to a connecting plate, which is flush with the horizontal desktop of the workbench body. Welding work areas and testing units are located on both sides of the connecting plate, respectively. Sliding rails are located on both sides of the opening, and the sliding rails are connected to the desktop of the workbench body. A clamping mechanism is located on the sliding rails.

[0009] Furthermore, one side of the base plate is inclined downwards, and a dust collection box is provided at the end of the inclined side.

[0010] Furthermore, the flipping mechanism includes:

[0011] A movable slot is provided on the mounting bracket, and a movable block is provided within the movable slot. One end of the movable block is slidably connected to the movable slot, and the other end is fixedly connected to one side of the connecting plate.

[0012] The moving slot has symmetrical drive gears on both sides below it. The two drive gears are rotatably connected to the side wall of the mounting frame. A drive chain is provided on the outer side of the two drive gears. A driven gear is fixedly connected to the outer side of the moving block. The driven gear meshes with the drive chain. One side of the mounting frame is rotatably connected to one end of a support rod. The other end of the support rod is rotatably connected to the middle of the connecting plate. A drive motor is also provided on one side of the mounting frame. The output shaft of the drive motor passes through the mounting frame and is driven by any one of the drive gears.

[0013] Furthermore, the flipping mechanism is also connected to a cleaning component, including two threaded screws with one end fixedly connected to the shafts of the two drive gears, and the other end of the threaded screws rotatably connected to the front side of the workbench body. The two threaded screws are respectively threaded to the two ends of a threaded sleeve, and the two ends of the threaded sleeve are respectively connected to the two ends of an anti-static brush.

[0014] Furthermore, the clamping mechanism includes:

[0015] A positioning base is slidably mounted on two sliding rails. Two parallel sliding rods are provided between the two positioning bases. The two ends of a fixed base are slidably sleeved on the outer sides of the two sliding rods. Clamping plates are also provided on both sides of the fixed base. The two ends of the clamping plates are slidably connected to the outer sides of the two sliding rods. A tension spring is sleeved on the outer side of each of the two sliding rods. One end of the tension spring is connected to the clamping plate, and the other end is connected to the fixed base. The fixed base is also provided with threaded holes in a direction perpendicular to the sliding rods. Fixing bolts are provided in the threaded holes. Telescopic rods are also provided at both ends of the clamping plates. Clamping blocks are connected to the telescopic rods.

[0016] Furthermore, a tool box is provided on one side of the storage cavity, and a tool hanging plate is provided above the opening, with an LED light strip on the top of the tool hanging plate.

[0017] Furthermore, the test unit includes a digital oscilloscope.

[0018] Furthermore, at least one of the positioning bases is also equipped with a welding magnifying glass.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] This invention uses a flipping mechanism to drive a drive gear to rotate, which in turn drives a chain with two synchronous gears to flip the connecting plate upwards, enabling rapid switching between the welding and testing areas. This solves the problem of space waste and operational fragmentation caused by the physical separation of the traditional welding and testing areas. The two functional areas share the same tabletop area, increasing the effective operating area of ​​the desktop and improving space reuse.

[0021] This invention utilizes a cleaning component that is synchronously linked with the flipping mechanism. The drive gear rotates synchronously to drive the threaded screw, which pushes the threaded sleeve to move axially. The anti-static brush closely adheres to the inclined base plate to clean, pushing the welding slag into the ash collection box. This solves the problems of welding slag contaminating the work surface, damaging precision instruments, and the low efficiency of manual cleaning. The welding slag is collected while the mechanism is flipping.

[0022] This utility model uses a dual-axis clamping mechanism. The positioning base (X-axis) moves along the sliding rail, and the fixed base (Y-axis) is adjusted along the sliding rod and locked in position by bolts. The external clamping plate stretches the spring to store energy, and automatically clamps the workpiece after being released. The telescopic rod is adapted to different lengths. This solves the problems of inflexible positioning, cumbersome operation and poor adaptability of traditional clamps. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1 to 6 The technical solution provided by this utility model is: a multifunctional electronic experimental workbench, comprising:

[0033] The test unit includes a test bench body 1, a display 2 mounted on the desktop of the test bench body 1, and adjustable feet 3 mounted around the bottom of the test bench body 1. The test unit includes a digital oscilloscope 16.

[0034] The workbench body 1 has an opening 4 on its desktop. Below the opening 4 are a storage cavity and a base plate 5. The storage cavity contains a mounting bracket 6. One side of the mounting bracket 6 is connected to the back of the workbench body 1, and the other side has a flipping mechanism 7. The flipping mechanism 7 is connected to a connecting plate 8. The connecting plate 8 is flush with the horizontal desktop of the workbench body 1. Welding work areas 9 and testing units are respectively provided on both sides of the connecting plate 8. Sliding rails 10 are provided on both sides of the opening 4. The sliding rails 10 are connected to the desktop of the workbench body 1, and clamping mechanisms 11 are provided on the sliding rails 10. One side of the base plate 5 is inclined downwards, and a dust collection box 12 is provided at the inclined end. A tool box 13 is also provided on one side of the storage cavity for storing large tools. A tool hanging plate 14 is provided above the opening 4 for storing small tools. An LED light strip 15 is provided on the top of the tool hanging plate 14 for illumination.

[0035] This solution integrates welding, testing, storage, and lighting functions into a compact workbench. A flipping mechanism 7 combines the welding work area 9 and the testing unit into a single unit, allowing for vertical rotation. This solves the problems of traditional experimental benches, such as limited functionality, low space utilization, and inconvenient operation. It improves work efficiency, saves space, enhances the working environment with better lighting, facilitates tool access and waste collection, and enables multi-functional integrated operation.

[0036] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 As a preferred embodiment of this application, the flipping mechanism 7 includes:

[0037] A movable slot 71 is provided on the mounting frame 6. A movable block 72 is provided in the movable slot 71. One end of the movable block 72 is slidably connected to the movable slot 71, and the other end is fixedly connected to one side of the connecting plate 8. Two drive gears 73 are symmetrically arranged on both sides below the movable slot 71. The two drive gears 73 are rotatably connected to the side wall of the mounting frame 6. A drive chain 74 is provided on the outer side of the two drive gears 73. A driven gear 75 is fixedly connected to the outer side of the movable block 72. The driven gear 75 meshes with the drive chain 74. One end of a support rod 76 is rotatably connected to one side of the mounting frame 6. The other end of the support rod 76 is rotatably connected to the middle of the connecting plate 8. A drive motor 77 is also provided on one side of the mounting frame 6. The output shaft of the drive motor 77 passes through the mounting frame 6 and is driven by any one of the drive gears 73.

[0038] The flipping mechanism 7 is also connected to a cleaning component, including two threaded screws 78 with one end fixedly connected to the shaft of the two drive gears 73, and the other end of the threaded screws 78 rotatably connected to the front side of the workbench body 1. The two threaded screws 78 are respectively threaded to the two ends of the threaded sleeves 79, and the two ends of the threaded sleeves 79 are respectively connected to the two ends of the antistatic brushes 70.

[0039] This embodiment is implemented as follows:

[0040] The drive motor 77 starts, driving the drive gear 73 connected to it to rotate. Through the transmission of the drive chain 74, it drives another drive gear 73 to rotate synchronously. The rotation of the drive chain 74 drives the driven gear 75 meshing with it to move. The driven gear 75 drives the moving block 72 fixedly connected to it to slide in the moving groove 71. The sliding of the moving block 72 pushes the connecting plate 8 to rotate upward around its connection point with the mounting bracket 6. One end of the support rod 76 is rotatably connected to the mounting bracket 6, and the other end is rotatably connected to the middle of the connecting plate 8. It provides support and stability during the rotation of the connecting plate 8, ensuring smooth movement of the connecting plate 8, and locks the position after it is rotated into place.

[0041] As the connecting plate 8 flips upward, the welding slag and debris on the surface of the welding work area 9 slide down along the tilt angle due to gravity and are directly poured onto the bottom plate 5 of the storage cavity below, falling into the waste box for collection and storage.

[0042] The cleaning components work as follows:

[0043] As the two drive gears 73 rotate, they drive the threaded screw 78, which is fixed coaxially with them, to rotate. The rotation of the threaded screw 78 causes the threaded sleeve 79 fitted on it to move along the screw axis. The anti-static brushes 70 connected to both ends of the threaded sleeve 79 move together with the threaded sleeve 79. The anti-static brushes 70, fixed to both ends of the threaded sleeve 79, move close to the surface of the base plate 5, pushing the residual solder slag and dust on the base plate 5 along the inclined base plate 5 to the lower end and sweeping them into the dust collection box 12. This solves the problems of traditional soldering stations and testing instruments being usually separated, occupying extra space, and the difficulty in cleaning solder slag and dust generated by soldering, which may damage precision instruments.

[0044] Controlled by drive motor 77, the system quickly and smoothly switches between the welding work area 9 and the testing unit, significantly improving operational convenience. The welding and testing areas are integrated onto a flip-up connecting plate 8, which is hidden under the tabletop during storage, greatly saving valuable desktop space.

[0045] When the flipping mechanism 7 moves, it automatically drives the cleaning brush to sweep away and collect debris and dust from the bottom plate 5 of the storage cavity, keeping it clean.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 As a preferred embodiment of this application, the clamping mechanism 11 includes:

[0047] Positioning bases 81 are slidably mounted on two sliding rail frames 10. Two parallel sliding rods 82 are provided between the two positioning bases 81. The two ends of a fixed base 83 are slidably sleeved on the outer sides of the two sliding rods 82. Clamping plates 84 are also provided on both sides of the fixed base 83. The clamping plates 84 are slidably connected to the outer sides of the two sliding rods 82 at both ends. Tension springs 85 are sleeved on the outer sides of each sliding rod 82. One end of each tension spring 85 is connected to the clamping plate 84, and the other end is connected to the fixed base 83. The fixed base 83 has threaded holes perpendicular to the sliding rods 82, and fixing bolts 86 are installed in the threaded holes. Telescopic rods 87 are also provided at both ends of the clamping plates 84, and clamping blocks 88 are connected to the telescopic rods 87. At least one of the positioning bases 81 is also equipped with a welding magnifying glass 17.

[0048] The working principle of the clamping mechanism 11 in this embodiment is as follows:

[0049] The positioning base 81 can slide freely along the sliding rails 10 on both sides of the workbench to determine the front and rear positions of the clamping mechanism 11 on the workbench. The fixing bolts 86 are screwed into the threaded holes of the fixing base 83 and pressed against the sliding rods 82 to firmly lock the fixing base 83 in the selected position. The fixing base 83 is fitted on the two parallel sliding rods 82 and can slide along the direction of the sliding rods 82 to determine the left and right positions of the clamping mechanism 11.

[0050] When it is necessary to clamp the workpiece, the clamping plate 84 is pulled outward, the tension spring 85 is stretched, and after the clamping plate 84 is released, the restoring force of the tension spring 85 pulls the clamping plate 84 toward the fixed base 83, thereby causing the clamping block 88 to clamp the workpiece located between the fixed base 83 and the clamping plate 84.

[0051] The telescopic rod 87 allows adjustment of the length of the clamping block 88 relative to the clamping plate 84 to accommodate workpieces of different lengths. The welding magnifying glass 17 is mounted on one of the positioning bases 81 and can move and be positioned together with the clamping mechanism 11 to provide a magnified field of view and assist in fine welding operations.

[0052] During electronic soldering and testing, small PCB boards, components, etc. need to be stably fixed. Traditional methods are unstable, require both hands, and require frequent adjustments to the position of the fixture on the table to adapt to different workpieces and operations.

[0053] This embodiment utilizes a tension spring 85 to achieve rapid and adaptive clamping, making operation simple and efficient, and freeing up both hands. The bidirectional sliding design of the positioning base 81 (X-axis) and the fixed base 83 (Y-axis) allows the clamping point to be precisely positioned arbitrarily within the plane of the worktable opening 4 area.

[0054] Working principle:

[0055] With the connecting plate 8 in a horizontal storage state and the welding work area 9 facing upwards, slide the clamping mechanism 11 along the sliding rail frame 10 to above the opening 4 (directly above the welding work area 9); adjust the positioning base 81 and the fixed base 83 for precise positioning, pull out the clamping plate 84 and place the PCB or workpiece, and after releasing, the tension spring 85 automatically clamps; the tool hanging plate 14 retrieves the welding tools, and the LED light strip 15 provides shadowless lighting. The operation is completed in the welding work area 9, and welding slag remains on the table surface.

[0056] Slide the clamping mechanism 11 down along the sliding rail frame 10 to the front end of the opening 4 (avoiding the flipping path), start the drive motor 77, and drive the connecting plate 8 to flip upward through the gear-chain transmission. The surface of the welding area tilts due to gravity, and the welding slag slides down along the connecting plate 8 and falls directly into the inclined bottom plate 5 of the storage cavity below. At the same time, when the drive gear 73 rotates, the linked threaded screw 78 rotates, and the threaded sleeve 79 drives the antistatic brush 70 to move from back to front along the bottom plate 5, completely pushing the residual debris into the ash collection box 12.

[0057] The connecting plate 8 flips into place, the test unit rises above the table, the support rod 76 is locked in position, the welding work area 9 is hidden under the table, test accessories can be taken from the tool box 13, or multimeters and other equipment can be taken out and put in the tool hanging plate 14 to assist in the test.

[0058] The multifunctional electronic experimental workbench provided by this utility model achieves efficient switching and concealed storage of the welding and testing work areas through an innovative flipping mechanism, solving the problems of space occupation and mode switching; the clamping mechanism provides a flexible, stable workpiece fixing solution with magnification assistance, greatly improving the convenience and accuracy of welding and testing operations; the linkage cleaning mechanism automatically cleans the workbench surface and prevents static electricity during the switching process, maintaining a clean and safe working environment; combined with the design of tool boxes, tool hanging boards, LED lighting, dust collection boxes, digital oscilloscopes, etc., it truly realizes a high degree of integration, automation and humanization of the functions required for electronic experiments, significantly improving work efficiency, saving space and improving the operating experience.

[0059] The parts not covered in this utility model are the same as or can be implemented using existing technologies.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
