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.

[0019] Example 1

[0020] Please see Figures 1-4 In this embodiment: a circuit board surface mount device includes a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, a support rod 3 fixedly connected to the inner upper surface of the workbench 2, a sliding sleeve 4 slidably connected to the outer wall of the support rod 3, a fixing frame 5 fixedly connected to the outer wall of the sliding sleeve 4, a connecting plate 6 rotatably connected to one side of the fixing frame 5, a connecting frame 7 rotatably connected to one side of the connecting plate 6, a support frame 9 fixedly connected to the inner wall of the workbench 2, a pull plate 8 rotatably connected to the inner side of the support frame 9, a connecting arm 10 rotatably connected to one side of the connecting frame 7, a slider 11 mounted on one side of the connecting arm 10, a rubber plate 12 fixedly connected to one side of the slider 11, the upper part of the pull plate 8 and the outer wall of the slider 11 are both slidably connected to the upper surface of the workbench 2, a drive assembly 13 is mounted in the middle of the inner lower surface of the workbench 2, and the pull plate 8 is mounted on the drive assembly 13.

[0021] In this embodiment, by placing the circuit board on the workbench 2 and then activating the drive assembly 13 to rotate the pull plate 8 on the support frame 9, the connecting frame 7 can connect to the plate 6. With the cooperation of the fixing frame 5, the sliding sleeve 4 can slide on the support rod 3. At the same time, the upper part of the pull plate 8 pulls the connecting arm 10, and the connecting arm 10 pulls the slider 11 to slide on the upper surface of the workbench 2. Thus, the slider 11 can drive the rubber plate 12 to clamp and fix the circuit board. Meanwhile, the rubber plate 12 and the slider 11 form a flexible support to avoid damage to the surface of the circuit board.

[0022] Furthermore, the drive assembly 13 includes a mounting plate 1301 and a motor 1302. The lower surface of the mounting plate 1301 is fixedly connected to the lower inner surface of the worktable 2. One side of the motor 1302 is fixedly connected to the lower inner surface of the worktable 2. The output end of the motor 1302 is fixedly connected to a drive bevel gear 1303. The surface of the mounting plate 1301 is rotatably connected to a screw 1304. One end of the screw 1304 is rotatably connected to the inner wall of the worktable 2. The other end of the screw 1304 is fixedly connected to a driven bevel gear 1305. The driven bevel gear 1305 meshes with the drive bevel gear 1303 around the perimeter. The outer wall of the screw 1304 is threadedly connected to an adjusting block 1306. The upper surface of the adjusting block 1306 is fixedly connected to a fixing rod 1307. The outer wall of the fixing rod 1307 is slidably connected to an adjusting frame 1308. The lower part of the pull plate 8 is rotatably connected to the adjusting frame 1308.

[0023] The motor 1302 drives the active bevel gear 1303 to rotate. The active bevel gear 1303 meshes with the driven bevel gear 1305, which in turn drives the screw 1304 to rotate. The rotation of the screw 1304 drives the adjusting frame 1308 to move through the adjusting block 1306 and the fixed rod 1307, thereby adjusting the position of the pull plate 8. When the pull plate 8 rotates, the adjusting frame 1308 slides on the fixed rod 1307, thereby achieving precise positioning of the circuit board.

[0024] Preferably, the upper surface of the workbench 2 is provided with a through groove 14 and a guide groove 15 around its perimeter. The upper outer wall of the pull plate 8 is slidably connected to the inner wall of the through groove 14, and the outer wall of the slider 11 is slidably connected to the inner wall of the guide groove 15.

[0025] The upper surface of the worktable 2 is designed with a through groove 14 and a guide groove 15 for cooperating with the pull plate 8 and the slider 11.

[0026] Furthermore, a mounting bracket 16 is fixedly connected to the upper surface of the base 1, an electric telescopic rod 17 is fixedly connected to the middle of the surface of the mounting bracket 16, a fixing plate 18 is fixedly connected to the output end of the electric telescopic rod 17, and a placement device 19 is fixedly connected to the lower surface of the fixing plate 18; buffer telescopic rods 20 are fixedly connected to both sides of the surface of the mounting bracket 16, and the bottom ends of the buffer telescopic rods 20 are fixedly connected to both sides of the upper surface of the fixing plate 18; the placement device 19 and the center of the worktable 2 are on the same axis.

[0027] The electric telescopic rod 17 is activated to control the vertical movement of the fixing plate 18, which in turn drives the placement device 19 to move up and down, thus achieving precise placement of components. At the same time, the buffer telescopic rod 20 effectively reduces the vibration generated during the placement process and improves operational stability.

[0028] The working principle and usage process of this utility model are as follows: The circuit board is placed on the workbench 2, and then the output of the motor 1302 drives the active bevel gear 1303 to rotate. The active bevel gear 1303 meshes with the driven bevel gear 1305, which in turn drives the screw 1304 to rotate. The rotation of the screw 1304 causes the adjusting frame 1308 to move via the adjusting block 1306 and the fixed rod 1307, allowing the pull plate 8 to rotate and adjust its position on the support frame 9. When the pull plate 8 rotates, the adjusting frame 1308 slides on the fixed rod 1307, thereby achieving precise positioning of the circuit board, and enabling the connecting frame 7 to connect. With the cooperation of the fixing frame 5, the plate 6 allows the sliding sleeve 4 to slide on the support rod 3. At the same time, the upper part of the pull plate 8 pulls the connecting arm 10, and the connecting arm 10 pulls the slider 11 to slide on the upper surface of the worktable 2. This allows the slider 11 to drive the rubber plate 12 to clamp and fix the circuit board. Meanwhile, the rubber plate 12 and the slider 11 form a flexible support to avoid damage to the surface of the circuit board. Then, the electric telescopic rod 17 is activated to control the fixing plate 18 to move up and down, which in turn drives the mounter 19 to move up and down, realizing the precise placement of components. At the same time, the buffer telescopic rod 20 effectively reduces the vibration generated during the mounting process and improves the stability of operation.

[0029] 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.
