[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments.
[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0026] The following is in conjunction with the appendix Figures 1-6This application will be described in further detail.
[0027] Reference Figures 1-3 This application discloses a multifunctional circuit board repair soldering workbench, including a processing table 1. An annular groove 2 is provided in the middle of the upper end of the processing table 1. A rotating component 3 is connected to one side of the upper end of the processing table 1. A multifunctional mounting plate 4 is connected to one side of the upper end of the processing table 1. The multifunctional mounting plate 4 facilitates the installation of different practical circuit boards. For example, a movable magnifying glass can be installed to facilitate the soldering personnel to magnify the solder joints and facilitate soldering. A fixed seat 5 is rotatably connected to one side of the upper end of the processing table 1. A groove 6 is provided on the upper end of the fixed seat 5. A fixing component 7 is connected inside the groove 6.
[0028] Among them, such as Figure 3 As shown, a movable plate 8 is connected to the lower end of the fixed base 5. The lower end of the movable plate 8 is located inside the annular groove 2. A ball bearing 9 is rotatably connected to the lower end of the movable plate 8. The rolling of the ball bearing 9 reduces the friction between the movable plate 8 and the annular groove 2, thereby saving effort and making it easier for the fixed base 5 to rotate. The outer side of the ball bearing 9 slides in contact with the inner side of the annular groove 2.
[0029] Reference Figure 4-5 The rotating assembly 3 includes a rotating shaft 31 installed inside the processing table 1. One end of the rotating shaft 31 is connected to the lower end of the processing table 1, and the other end of the rotating shaft 31 is connected to a gear disk 32. The upper end of the gear disk 32 is rotatably connected to the lower end of the processing table 1. A gear 33 is meshed on one side of the gear disk 32. A gear plate is meshed with the gear disk 32. When the gear 33 rotates, the gear disk 32 rotates. Under the meshing transmission of the gear disk 32 and the gear disk 32, the rotating shaft 31 is driven to rotate, which in turn drives the fixed seat 5 to rotate. One end of the gear 33 is connected to a round rod 34, and the upper end of the round rod 34 extends through to the top of the processing table 1.
[0030] Among them, such as Figure 5 As shown, a rotating sleeve 35 is slidably sleeved on the outside of the round rod 34. A slider 36 is connected to the inside of the rotating sleeve 35. One end of the slider 36 is slidably connected to the round rod 34. A groove 37 is provided at the sliding connection point of the round rod 34 and the slider 36. The slider 36 is located inside the groove 37. A sliding rod 38 is connected through one end of the slider 36. The slider 36 slides and limits the slider 36, so that the slider 36 slides along the inside of the groove 37 and will not detach. Under the sliding setting of the slider 36 and the groove 37, the rotating sleeve 35 moves up and down along the outside of the round rod 34. Both ends of the sliding rod 38 are connected to the inner walls of the groove 37. A spring 39 is sleeved on the outside of the sliding rod 38.
[0031] Additionally, one end of spring 39 is connected to one side of slider 36. When rotating sleeve 35 moves upward, it compresses spring 39, causing it to be in a compressed state. When rotating sleeve 35 is released, under the elastic potential energy of spring 39, rotating sleeve 35 moves back to its original position, and limiting rod 312 is located in limiting groove 311. The other end of spring 39 is connected to one side of inner wall of slide groove 37. Limiting plate 310 is connected to the lower end of rotating sleeve 35. Limiting groove 311 is formed on the outside of limiting plate 310. One side of upper end of processing table 1 is connected to... The limiting rod 312 is located inside the limiting groove 311. When the limiting plate 310 is located inside the limiting groove 311, the rotating sleeve 35 and the round rod 34 are fixedly connected. At this time, the fixed seat 5 is in a fixed state. When it is necessary to rotate the fixed seat 5, the rotating sleeve 35 is pulled upward, so that the rotating sleeve 35 drives the limiting plate 310 to move. When the limiting plate 310 is not in contact with the limiting rod 312, the rotating sleeve 35 is rotated, and the rotating sleeve 35 drives the round rod 34 to rotate, thereby causing the fixed seat 5 to rotate.
[0032] Reference Figure 6 The fixing component 7 includes a lead screw 71 installed inside one side of the groove 6. One end of the lead screw 71 extends through to the outside of the fixing seat 5. A push plate 72 is threaded onto the outside of the lead screw 71. When the lead screw 71 is rotated, the lead screw 71 is threadedly connected to the push plate 72. The rotation of the lead screw 71 drives the push plate 72 to move. The push plate 72 drives the clamping plate 73 to clamp and fix the circuit board, ensuring the stability of the circuit board during soldering. A clamping plate 73 is connected to the upper end of the push plate 72. A rubber strip 75 is connected to one end of the clamping plate 73. The rubber strip 75 is made of soft material. The rubber strip 75 moves with the clamping plate 73 and contacts the edge of the circuit board, reducing the hard contact between the clamping plate 73 and the object, preventing damage or displacement of the circuit board due to vibration during clamping, and ensuring that the circuit board will not deform when firmly fixed.
[0033] The clamping plate 73 has an adsorption hole 76 at one end, through which the exhaust gas is absorbed into the absorption pipe 77. The clamping plate 73 is connected to the absorption pipe 77 at one end, which extends into the clamping plate 73. The other end of the absorption pipe 77 is connected to a suction fan 78, which generates suction to absorb the exhaust gas. The lower end of the suction fan 78 is connected to the upper end of the processing table 1, and the output end of the suction fan 78 is connected to an exhaust box 79. The exhaust box 79 is equipped with activated carbon adsorption filter plates and organic resin adsorption filter plates to absorb the exhaust gas generated during welding, adsorb it, and then discharge it to avoid environmental pollution and ensure the health of the staff.
[0034] The implementation principle of the multifunctional circuit board repair welding workbench of this application embodiment is as follows: When in use, the circuit board to be processed is placed on the upper end of the fixed base 5, and the lead screw 71 is rotated so that multiple clamping plates 73 limit and fix the circuit board to ensure the stability of the circuit board. The exhaust gas generated during the welding process is absorbed through the adsorption hole 76 and discharged under the filtration of the discharge box 79 to avoid polluting the environment and at the same time ensure the health of the staff.
[0035] In the initial state, the limiting rod 312 is located inside the limiting groove 311, and the round rod 34 is fixedly connected. Therefore, the fixed seat 5 is fixed. When different positions of the circuit board need to be processed, the rotating sleeve 35 is pulled upward. The rotating sleeve 35 drives the limiting plate 310 to move. When the limiting plate 310 is not in contact with the limiting rod 312, the rotating sleeve 35 is rotated. The rotating sleeve 35 drives the round rod 34 to rotate. The round rod 34 drives the gear 33 to rotate. Under the meshing transmission of the gear 33 and the gear plate 32, the fixed seat 5 is rotated, which makes it convenient for the operator to perform soldering operations on the circuit board from different angles.
[0036] The suction fan is an existing technology and is widely used in society. The specific model of the suction fan can be selected according to the actual production needs, so it will not be described in detail. All electrical components mentioned in this application are connected to an external power supply and control switch during use.
[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
