Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a circuit board soldering device for electrical connectors. Background Technology

[0002] Electrical connectors are conductive devices used to transmit electronic data. They are widely used in various transmission lines. The connections formed by electrical connectors can be temporary and easy to plug and unplug, or they can be permanent nodes between transmission devices. Electrical connectors mainly include PCB connectors, rectangular I / O, circular I / O, CPU sockets, RF coaxial connectors, fiber optic connectors, and high-voltage connectors. Currently, domestic manufacturers primarily produce PCB connectors and rectangular I / O. Common electrical connectors typically have a circuit board inside that inserts into a connector slot, allowing the circuit board to make electrical contact with the conductive pins in the slot, thus enabling the transmission of electronic data between electronic devices.

[0003] The manufacturing of electrical connectors typically involves soldering the connector pins to the circuit board. However, the pin length of the connector after manufacturing often differs from the actual dimensions required for assembly and soldering. To meet these requirements, the pin length needs to be trimmed to the optimal length depending on the specific product's operating conditions. Pin trimming can be done before or after soldering, but this requires two separate workstations: one for soldering the circuit board and the other for trimming the pins. This separate process is time-consuming, space-consuming, costly, and prevents rapid circuit board soldering and trimming. Therefore, an improvement is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a circuit board soldering device for electrical connectors, solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A circuit board soldering apparatus for electrical connectors includes a worktable and further includes:

[0009] A welding module, wherein the welding module is mounted on a support frame provided on the upper surface of the workbench;

[0010] A trimming module, mounted on a workbench, is used to trim the pins of a circuit board.

[0011] The loading module is mounted on a workbench and includes a base plate fixedly connected to the upper surface of the workbench and a first pneumatic cylinder mounted on the base plate. A rack is fixedly connected to the output shaft of the first pneumatic cylinder. Support seats are fixedly connected to both sides of the rack on the base plate, and a special-shaped gear is rotatably connected to the top of the support seats. The rack meshes with the special-shaped gear, and a material positioning plate for loading circuit boards is fixedly connected to one side of the special-shaped gear. When the first pneumatic cylinder drives the rack to extend and retract, it can drive the special-shaped gear to rotate, thereby adjusting the angle of the material positioning plate and realizing the welding and trimming operations of the circuit boards.

[0012] Furthermore, a track is fixedly connected to the upper surface of the base plate along the extension and retraction direction of the rack, and a slider is fixedly connected to the end of the rack, the slider being slidably connected to the track.

[0013] Furthermore, the material positioning plate is provided with a negative pressure hole that runs vertically through it.

[0014] Furthermore, a negative pressure module is installed on the workbench. The negative pressure module includes a frame fixedly connected to the workbench and a negative pressure pump installed on the frame. The suction port of the negative pressure pump is connected to a negative pressure hose, and the end of the negative pressure hose is connected to a negative pressure hole at the bottom of the material positioning plate.

[0015] Furthermore, the trimming module includes a mounting frame fixedly connected to the surface of the workbench, and a second pneumatic cylinder mounted on the mounting frame. A pneumatic scissors is fixed on a telescopic plate at the end of the output shaft of the second pneumatic cylinder, and an air supply pipe is connected to the pneumatic scissors.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a circuit board soldering device for electrical connectors, which has the following advantages:

[0020] This invention utilizes a loading module installed on a workbench. This module is used for positioning and loading circuit boards onto a material positioning plate. When the first pneumatic cylinder operates, it drives a rack and pinion to extend and retract. The meshing relationship between the rack and pinion causes the pinion to rotate, which in turn rotates the material positioning plate and the circuit board. When the angle of the circuit board changes, other processes can be performed, including soldering and pin trimming. Soldering and trimming can be done at the same workstation, eliminating the need for separate operations. This reduces equipment space requirements and costs while increasing efficiency and significantly shortening circuit board soldering time, making it suitable for practical use.

[0029] It should be noted that workbench 1 is used for soldering circuit boards and installing other modules. A soldering module 3 is installed on the support frame 4 on the upper surface of workbench 1. The soldering module 3 performs soldering of the circuit boards using known existing technology, which will not be elaborated upon. A trimming module 6 is installed on workbench 1 to trim the pins to the corresponding length. A loading module 5 is installed on workbench 1 to support and fix the circuit boards. During use, the circuit board to be processed is placed on the material positioning plate 508. When the material positioning plate 508 is at the water surface position, the circuit board is then... The circuit board is soldered through the welding module 3. Before or after soldering, the pins can be trimmed through the trimming module 6. When trimming is required, the first pneumatic cylinder 502 is driven to work. The first pneumatic cylinder 502 drives the rack 503 to extend and retract. Through the meshing relationship between the rack 503 and the special gear 507, the special gear 507 is driven to rotate on the support base 504, which in turn drives the material positioning plate 508 to adjust the angle of the material positioning plate 508.

The negative pressure pump 202 can draw air through the negative pressure hose 203. The end of the negative pressure hose 203 is connected to the negative pressure hole 509 to achieve the adsorption and fixation of the circuit board.
