The soldering device can be designed differently according to the type and requirements of soldering, such as surface mount soldering, wave soldering, reflow soldering, etc.

[0003] The existing soldering devices for electronic component manufacturing have the following disadvantages during use:

[0004] When soldering electronic components to a printed circuit board, it is necessary to first clamp and fix the circuit board components through manual clamping tools, and then solder the electronic components onto the circuit board through an electric soldering assembly. Such an operation process results in low efficiency during soldering, and it is impossible to achieve clamping and fixing of the circuit board during the downward movement of the electric soldering assembly. Therefore, a soldering device for electronic component manufacturing is needed. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A soldering device for electronic component manufacturing, including a soldering table and an electric soldering assembly. The top of the soldering table is connected with a moving table through a manual moving structure. A lead screw drive module a is installed at the top of the soldering table behind the moving table. The lead screw drive module a is drivingly connected with a lifting rod. One end of the lifting rod far from the lead screw drive module a is fixedly connected with a lead screw drive module b. The lead screw drive module b is drivingly connected with a horizontal moving rod. The electric soldering assembly is installed on the horizontal moving rod;

[0007] It further includes a synchronous drive structure and a movable clamping structure. The synchronous drive structure is installed on the outer wall of the lead screw drive module a and is connected with the lifting rod. The synchronous drive structure is also connected with the movable clamping structure through an adjusting member. The movable clamping structure is installed on the top of the moving table.

[0008] As a preferred implementation manner, the synchronous drive structure includes guide rods fixedly connected to both side walls of the lead screw drive module a. Sliding sleeves are slidably sleeved on the outer sides of the two guide rods. Transmission plates are fixedly connected to the front ends of the sliding sleeves.

[0009] As a preferred embodiment, drive channels with a structure whose vertical cross-section is in the shape of a "hockey stick" are formed on the drive plates. Drive columns are movably lapped in the drive channels. Connecting rods are fixedly connected to the front ends of the two drive columns. The two connecting rods are symmetrically fixed on the outer side of the lifting rod.

[0010] As a preferred embodiment, the adjusting member includes moving channels formed at the bottom ends of the two drive plates. The vertical cross-sections of the moving channels are both in an inverted "convex" shape structure. Adjusting rods with a vertical cross-section in an inverted "convex" shape structure are movably inserted in the moving channels. Hand-tightening screws are threadedly penetrated and connected to the two drive plates. The length of the hand-tightening screws is greater than the length of the drive plates. The bottom ends of the hand-tightening screws after being tightened abut against the top ends of the adjusting rods.

[0011] As a preferred embodiment, the movable clamping structure includes drive rods fixedly connected to the bottom ends of the two adjusting rods.

[0014] In the present utility model, when using the soldering device for manufacturing electronic components, the lifting rod can be driven by the lead screw drive module a to drive the lead screw drive module b to move downward, so that the electric soldering assembly connected to the lead screw drive module b through the horizontal moving rod can descend and approach the top of the moving table. At the same time, the lifting rod drives the drive columns connected to the two connecting rods to move downward, and in cooperation with the setting of the drive channels, further enables the two drive plates to move relatively toward each other, and respectively drives the drive rods connected to the adjusting member to move relatively toward each other. However, the drive rods are sleeved on the tops of the L-shaped guide bars through the drive grooves, so that the two L-shaped guide bars drive the clamping plates to move relatively toward each other, thereby realizing the active clamping action of the circuit board, without manual interference in clamping and fixing the circuit board, greatly improving the fixing efficiency of the circuit board. In addition, by loosening the hand-tightening screws, the distance between the two drive rods can be adjusted. In cooperation with the action of the L-shaped guide bars, the pre-spacing between the two clamping plates can be conveniently adjusted to facilitate clamping and fixing of circuit boards of different sizes, with a wide range of applications. In addition, combined with the action of the manual moving structure, the circuit board after being clamped and fixed can also be moved back and forth on the top of the soldering table through the moving table to meet the requirements for soldering different positions on the clamped circuit board.

[0023] Embodiment

[0024] When soldering electronic components to a printed circuit board, it is necessary to first clamp and fix the circuit board components with a manual clamping tool, and then solder the electronic components to the circuit board through the electric soldering assembly 61. Such an operation process results in low efficiency during soldering and cannot achieve the clamping and fixing of the circuit board when the electric soldering assembly 61 is descending;

[0025] Therefore, please refer to Figures 1-4 , the present utility model provides a soldering device for manufacturing electronic components, including: a soldering table 1 and an electric soldering assembly 61. The top of the soldering table 1 is connected with a moving table 2 through a manual moving structure. A lead screw drive module a3 installed on the top of the soldering table 1 is provided at the rear of the moving table 2. The lead screw drive module a3 is drivingly connected with a lifting rod 4. One end of the lifting rod 4 far from the lead screw drive module a3 is fixedly connected with a lead screw drive module b5. The lead screw drive module b5 is drivingly connected with a horizontal moving rod 6. The electric soldering assembly 61 is installed on the horizontal moving rod 6. The lead screw drive module a3 can facilitate the lifting action of the lifting rod 4, and the lead screw drive module b5 can perform horizontal movement adjustment of the electric soldering assembly 61 on the horizontal moving rod 6;

[0026] It also includes a synchronous drive structure 7 and a movable clamping structure 9. The synchronous drive structure 7 is installed on the outer wall of the lead screw drive module a3 and is connected with the lifting rod 4. The synchronous drive structure 7 is also connected with the movable clamping structure 9 through an adjusting member 8. The movable clamping structure is installed on the top of the moving table 2.

[0027] Among them, the manual moving structure includes a sliding seat 21 fixedly connected to the bottom end of the moving table 2. The sliding seat 21 is slidably connected to a sliding groove provided at the top of the soldering table 1. A screw 22 is threadedly connected to the sliding seat 21. Both ends of the screw 22 are rotatably connected to the sliding groove, and the front end extends to the front side of the soldering table 1 and is fixedly connected with a handwheel 23.

[0028] Furthermore, as Figures 1-4 shown, it is specifically noted that in order to be able to actively achieve the clamping action of the circuit board during the downward movement of the electric soldering assembly 61, the synchronous drive structure 7 is provided. The synchronous drive structure 7 includes guide rods 73 fixedly connected to both side walls of the lead screw drive module a3. Sliding sleeves 72 are slidably sleeved on the outer sides of the two guide rods 73. Transmission plates 71 are fixedly connected to the front ends of the sliding sleeves 72. Transmission channels 74 with a cross-section in the shape of a "hockey stick" are provided on the transmission plates 71. Transmission columns 75 are movably lapped in the transmission channels 74. Connecting rods 76 are fixedly connected to the front ends of the two transmission columns 75. The two connecting rods 76 are symmetrically fixed on the outer side of the lifting rod 4.

[0029] Among them, the width of the transmission channel 74 is equal to the diameter of the transmission column 75.

[0030] Further, as Figures 1-4 shown, it is worth specifically explaining that in order to facilitate the adjustment of the initial distance between the two clamping plates 92, so that during the downward movement of the electric welding assembly 61, the circuit boards of different sizes can be actively clamped and fixed. Therefore, the adjusting member 8 is provided with movable channels opened at the bottom ends of the two transmission plates 71. The vertical cross-sections of the movable channels are both in an inverted "convex" shape structure. Adjusting rods 81 with an inverted "convex" shape structure in the vertical cross-section are movably inserted into the movable channels. Hand-tightening screws 82 are threadedly penetrated and connected to the two transmission plates 71. The length of the hand-tightening screw 82 is larger than the length of the transmission plate 71. The bottom ends of the hand-tightening screws 82 after being tightened are all pressed against the top ends of the adjusting rods 81.

[0031] Among them, the vertical cross-sections of the movable channels are both in an inverted "convex" shape structure to ensure the horizontal movement of the adjusting rod 81 in the horizontal direction and prevent it from falling off easily.

[0032] Further, as Figures 1-4 shown, it is worth specifically explaining that in order to enable the two clamping plates 92 to clamp and fix the circuit board, and also enable the clamped and fixed circuit board to cooperate with the manual moving structure for front-back manual movement. Therefore, the movable clamping structure 9 is provided with transmission rods 94 fixedly connected to the bottom ends of the two adjusting rods 81. The bottom ends of the transmission rods 94 are slidably sleeved on the top of the L-shaped guide bars 93 through the provided transmission grooves. Clamping plates 92 are fixedly connected to the bottom ends of the L-shaped guide bars 93. Sliders 91 with a convex shape structure in the vertical cross-section are fixedly connected to the bottom ends of the clamping plates 92. The two sliders 91 are slidably connected to the sliding grooves provided at the top end of the moving table 2. The vertical cross-sections of the tops of the L-shaped guide bars 93 are both in an inverted "right trapezoid" structure.

[0033] Among them, the shape of the transmission groove is as shown in the appendix Figure 4 so that the L-shaped guide bar 93 can move inside it and is not easily separated, and the length of the L-shaped guide bar 93 is smaller than the length of the transmission rod 94.

[0034] In summary, when using the welding device for manufacturing electronic components, the lifting rod 4 can be driven by the lead screw drive module a3 to drive the lead screw drive module b5 to move downward, so that the electric welding assembly 61 connected to the lead screw drive module b5 through the horizontal moving rod 6 can descend and approach the top of the moving table 2. At the same time, the lifting rod 4 drives the transmission columns 75 connected to the two connecting rods 76 to move downward, and in cooperation with the arrangement of the transmission channels 74, the two transmission plates 71 can move relatively toward each other, and respectively drive the transmission rods 94 connected to the adjusting member 8 to move relatively toward each other. However, the transmission rods 94 are sleeved on the top of the L-shaped guide strips 93 through the transmission grooves, so that the two L-shaped guide strips 93 drive the clamping plates 92 to move relatively toward each other, thereby realizing the active clamping action of the circuit board, without manual interference in clamping and fixing the circuit board, greatly improving the fixing efficiency of the circuit board. In addition, by loosening the hand-tightened screw 82, the distance between the two transmission rods 94 can be adjusted. In cooperation with the function of the L-shaped guide strips 93, the pre-spacing between the two clamping plates 92 can be conveniently adjusted to facilitate clamping and fixing of circuit boards of different sizes, with a wide range of applications. In addition, combined with the function of the manual moving structure, the circuit board after being clamped and fixed can also move back and forth on the top of the welding table 1 through the moving table 2 to meet the requirements for welding different positions on the clamped circuit board.
