DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0035] First embodiment

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic structural diagram of a first embodiment of a PCB board welding machine provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the base structure shown; Figure 3 for Figure 1 The schematic diagram of the installation frame structure shown; Figure 4 for Figure 1 The schematic diagram of the moving assembly and the limit frame structure shown; Figure 5 for Figure 1 The schematic diagram of the limit frame structure shown; Figure 6 for Figure 5 The enlarged schematic diagram of part A is shown. A PCB board welding machine comprises: a base 1;

[0037] A lifting frame 2, the lifting frame 2 is fixedly installed on the top of the base 1, a transverse driving member 21 is fixedly installed on the bottom of the lifting frame 2, a longitudinal driving member 22 is fixedly installed on the moving end of the transverse driving member 21, a welding head 23 is fixedly installed on the moving end of the longitudinal driving member 22, and a welding device 24 is fixedly installed on the top of the lifting frame 2;

[0038] A mounting frame 3, the mounting frame 3 is fixedly mounted on the top of the base 1, and abutment plates 31 are fixedly mounted on both sides of the inner side surface of the mounting frame 3;

[0039] A moving component 4, wherein the moving component 4 is arranged at the bottom of the inner side surface of the installation frame 3;

[0040] Two limit frames 5, both of which are arranged on the top of the moving component 4, and clamping plates 51 are arranged at both ends of the inner sides of the two limit frames 5, and a moving plate 52 is fixedly installed on one side of the clamping plate 51, and a ball 53 is rollingly connected to one end of the moving plate 52, and a spring 54 is sleeved on the outer side surface of the moving plate 52.

[0041] When the lifting frame 2 is in use, it can move up and down, thereby driving the welding head 23 to move up and down;

[0042] The welding head 23 can be driven to move forward, backward, left and right by the driving of the transverse driving member 21 and the longitudinal driving member 22;

[0043] The two sides of the abutting plate 31 are inclined and the middle is convex, so that by cooperating with the moving plate 52, the clamping plate 51 can be pushed to move toward the middle.

[0044] The bottom of the base 1 is fixedly provided with feet 11 around it.

[0045] The bottom foot 11 is made of rubber material, which can prevent slipping during use.

[0046] The moving assembly 4 includes two fixed blocks 41, a driving motor 42, a screw rod 43, a moving block 44 and a mounting bracket 45. The two fixed blocks 41 are respectively fixedly installed at the two ends of the bottom of the inner side surface of the mounting frame 3, the driving motor 42 is fixedly installed on the side surface of one of the fixed blocks 41, the screw rod 43 is fixedly installed on the output end of the driving motor 42, the moving block 44 is threadedly connected to the outer side surface of the screw rod 43, and the mounting bracket 45 is fixedly installed on the top of the moving block 44.

[0047] When in use, the driving motor 42 rotates, which can drive the screw rod 43 to be threadedly connected inside the moving block 44, thereby driving the two limit frames 5 to move left and right through the mounting frame 45.

[0048] The mounting frame 45 is fixedly mounted on the bottom of the two limiting frames 5 , and two ends of the moving block 44 are respectively abutted against two sides of the inner side surface of the mounting frame 3 .

[0049] The two ends of the moving block 44 are respectively in contact with the two sides of the inner side surface of the installation frame 3 , so that the moving block 44 can be limited when in use.

[0050] One end of the spring 54 is fixedly mounted on one side of the clamping plate 51 , and the other end of the spring 54 is fixedly mounted on one end of the inner side surface of the limiting frame 5 .

[0051] The clamping plate 51 is pulled by the spring 54 , and after the welding is completed, the clamping plate 51 can be driven to reset, so that the staff can unload the PCB board.

[0052] Fixed limit plates 56 are provided at both ends of the top of the clamping plate 51. A sliding groove 55 is opened on the side of the clamping plate 51. A locking screw 57 is provided on the inner side of the sliding groove 55. One end of the locking screw 57 is threadedly connected to the inside of one end of the limit plate 56.

[0053] The setting of the limit plate 56 can limit the PCB board to avoid the PCB board moving left and right when the limit frame 5 moves. The limit plate 56 can be limited by locking the locking screw 57. When the locking screw 57 is loosened, the staff can adjust the position of the limit plate 56 conveniently.

[0054] The working principle of a PCB board welding machine provided by the present invention is as follows:

[0055] When in use, the user places the PCB board to be soldered in the limit frame 5 at the end face of the installation frame 3, and makes the bottom of the PCB board abut against the top of the clamping plate 51. Then the user starts the drive motor 42, so that the drive motor 42 drives the screw rod 43 to be threadedly connected inside the moving block 44, thereby driving the limit frame 5 to move to the center position of the installation frame 3. When the limit frame 5 moves, the balls 53 at both ends of the limit frame 5 will move along the inclined surface of the abutment plate 31 to the convex surface of the abutment plate 31. At this time, the moving plate 52 will clamp The holding plate 51 is pushed, so that the two clamping plates 51 on the limit frame 5 clamp and limit the PCB board, and at the same time, the limit frame 5 previously located at the center position of the installation frame 3 will move to the other end face of the installation frame 3. At this time, the staff can install the next PCB board to be welded on the inner side face of the limit frame 5. After the welding of the previous PCB board is completed, the driving motor 42 will reverse, so that the PCB board after welding is moved to the end face of the installation frame 3. At the same time, the clamping plate 51 will cancel the clamping limit of the PCB board, so that the staff can subsequently carry out unloading and loading.

[0056] Compared with the related art, the PCB welding machine provided by the present invention has the following beneficial effects:

[0057] By means of the cooperation of the structures such as the mounting frame 3, the abutment plate 31, the moving assembly 4, the limit frame 5, the clamping plate 51, the moving plate 52, the ball bearing 53, the spring 54 and the limit plate 56, when welding a PCB board on one of the limit frames 5, another PCB board to be welded can be loaded onto the other limit frame 5, so that welding and loading and unloading can be carried out simultaneously without waiting, thereby increasing the efficiency of welding the PCB boards.
