[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Since the polishing areas required for circuit boards of different specifications are different, for circuit boards with smaller areas, the staff can polish the circuit boards by operating a single polishing machine, and the time consumed is still relatively short. For circuit boards with larger areas, the staff cannot control two small polishing machines at the same time, so they still need to use a single polishing machine for polishing, which consumes more time and results in lower working efficiency of the device. The following describes a polishing device for circuit board production provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] Combination Figure 1-Figure 4 As shown, a polishing device for circuit board production includes a shell mechanism 1 as the main body of the device, and various mechanisms are connected to each other through the shell mechanism 1. Fixing mechanisms 2 are arranged on opposite sides of two connecting platforms 102, and the fixing mechanisms 2 are used to fix and clamp various circuit boards. Two polishing mechanisms 3 are symmetrically arranged between the two connecting platforms 102. The circuit boards are polished at multiple positions through the two opposite polishing mechanisms 3, which reduces the time required for polishing, thereby improving the working efficiency of the device.

[0025] The polishing mechanism 3 includes a fixed block 301, a guide rod 303 is fixedly connected to one side between the two connecting platforms 102, a driving screw 302 is rotatably connected to the other side between the two connecting platforms 102, a concave limit block 304 is fixedly connected to the top of the fixed block 301, a polishing assembly 305 is arranged on one side of the fixed block 301, a motor for controlling the driving screw 302 is installed inside one side of a connecting platform 102, the driving screw 302 is threadedly connected to a fixed block 301, the guide rod 303 is slidably connected to the other fixed block 301, a fixed rod is fixedly connected between the two fixed blocks 301, the driving screw 302 is driven to rotate by the motor, and under the action of the guide rod 303 and the fixed rod, the two fixed blocks 301 can move synchronously, so that the polishing assembly 305 can locate the polishing position of the circuit board, thereby performing reciprocating polishing.

[0026] The polishing assembly 305 includes a connecting block 3051 fixedly connected to one side of the fixed block 301, a circular plate 3052 is rotatably connected to the top of the connecting block 3051, a circular groove is provided on the truncated table 3056, a sliding plate 3057 is slidably connected in the concave stop block 304, a round rod 3058 is fixedly connected to the bottom of one end of the sliding plate 3057, the round rod 3058 is located in the circular groove, one end of the sliding plate 3057 is fixedly connected to the connecting plate 306, the bottom of the connecting plate 306 is rotatably connected to the polishing wheel 307, a micro motor for driving the polishing wheel 307 is installed on the top of the connecting plate 306, and the connecting plate 306 is connected to the polishing wheel 307. A servo motor for driving the circular plate 3052 to rotate is installed at the bottom of the block 3051. The servo motor drives the circular plate 3052 to rotate, so that the round table 3056 on the circular plate 3052 can rotate, and the round rod 3058 at the bottom of the sliding plate 3057 can move in the circular groove, thereby driving the connecting plate 306 to move back and forth through the sliding plate 3057. At this time, the micro motor drives the polishing wheel 307 to rotate. Under the action of the connecting plate 306, the polishing wheel 307 can reciprocate and polish the circuit board, so that the polishing efficiency of the two polishing components 305 on the circuit board is greatly improved.

[0027] The fixing mechanism 2 includes an electric telescopic rod 201 installed on one side of the connecting platform 102. The movable ends of the two electric telescopic rods 201 are fixedly connected with L-shaped clamps 202. The other sides opposite to the two L-shaped clamps 202 are installed with rubber pads. By controlling the two electric telescopic rods 201 to extend and retract, the circuit board between the two L-shaped clamps 202 can be stably clamped. Under the action of the rubber pad, the edge of the circuit board can be ensured not to be worn, thereby ensuring the production quality of the circuit board.

[0028] Embodiment 2:

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that for circuit boards with larger areas, the staff cannot control two small polishing machines at the same time, resulting in slow polishing efficiency of the device. However, when polishing circuit boards of different specifications, if the reciprocating distance of the sliding plate 3057 on the concave limit block 304 cannot be adjusted, it will cause gaps in the polishing path of the polishing wheel 307 for some circuit boards, resulting in poor polishing effect.

[0031] The shell mechanism 1 includes a support platform 101, and two connecting platforms 102 are fixedly connected to the top of the support platform 101. A trapezoidal hole 103 is opened on the bottom wall of the support platform 101. The center of the bottom wall of the support platform 101 is hollow. The various mechanisms are connected and fixed by the support platform 101 and the two connecting platforms 102. The trapezoidal hole 103 allows the debris in the polishing process to slide to the center of the support platform 101, which is convenient for collecting the debris and reduces the workload of the staff.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
