Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and specifically relates to an electronic product clamping mechanism, a welding wire conveying device and welding equipment. Background Art

[0002] Electronic products contain electronic components and circuit boards. Electronic product welding equipment is a tool used to connect electronic components to circuit boards. When using welding equipment, you first need to heat the soldering iron to a sufficient temperature, then align the electronic components with the circuit board, and then contact the solder wire with the soldering iron to melt the solder and apply it to the electronic components to be connected, so that the electronic components are connected to the circuit board through soldering, so that the electronic components can work properly. Welding equipment plays a key role in the manufacture and maintenance of electronic products. It can be used to connect electronic components, repair disconnected circuits, replace damaged components, etc. By using welding equipment, you can ensure the normal operation of electronic products and extend their service life.

[0003] The welding equipment includes a welding wire feeding device, through which the welding wire is fed and aligned with the welding point, so that the welding equipment can continue the welding operation.

[0044] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] Please see attached Figures 1 to 5 The electronic product clamping mechanism 10 of the embodiment of the utility model includes a connecting frame 100, a bearing block 200, a connecting plate 300, a driving member 400, a clamping block 500 and an ejector rod 600.

[0048] There are two bearing blocks 200, which are arranged at intervals and fixedly connected to the upper side of the connecting frame 100, and the two bearing blocks 200 are arranged symmetrically. There are two connecting plates 300, which are arranged symmetrically and fixedly connected to the two bearing blocks 200 respectively. Each connecting plate 300 is provided with a threaded hole 301, and the threaded holes 301 of the two connecting plates 300 are rotated in opposite directions. A mounting groove 302 is provided on one side of each connecting plate 300 adjacent to another connecting plate 300, and each connecting plate 300 is also provided with a through screw hole 303, and the screw hole 303 of each connecting plate 300 is connected to the corresponding mounting groove 302. The driving member 400 is respectively provided in the threaded holes 301 of the two connecting plates 300, and is respectively threadedly connected to the two connecting plates 300. There are two clamping blocks 500, which are symmetrically arranged. The two clamping blocks 500 are respectively fixedly embedded in the mounting grooves 302 of the two connecting plates 300. A clamping groove is provided on one side of each clamping block 500 adjacent to another clamping block 500. The clamping grooves of the two clamping blocks 500 are arranged opposite to each other. The inner walls of the clamping grooves of the two clamping blocks 500 clamp the welding wire together. There are two ejector rods 600, which are arranged one-to-one with the two connecting plates 300. Each ejector rod 600 is passed through the screw hole 303 of the corresponding connecting plate 300 and is threadedly connected to the corresponding connecting plate 300.

[0049] In this embodiment, when the clamping block 500 is removed, the ejector rod 600 is rotated so that the ejector rod 600 moves toward the clamping block 500. As the ejector rod 600 rotates, the ejector rod 600 pushes the clamping block 500 so that the clamping block 500 is separated from the mounting groove 302, and then the clamping block 500 is removed. When the clamping block 500 is installed, the ejector rod 600 is rotated so that the ejector rod 600 leaves the mounting groove 302, and then the clamping block 500 is embedded in the mounting groove 302.

[0050] The electronic product clamping mechanism 10 provided by the utility model, when the clamping block 500 is disassembled, the ejector rod 600 is rotated to make the ejector rod 600 move toward the clamping block 500. As the ejector rod 600 rotates, the ejector rod 600 will push the clamping block 500, so that the clamping block 500 is separated from the installation groove 302, thereby reducing the tightness of the connection between the clamping block 500 and the connecting plate 300, reducing the difficulty of removing the clamping block 500 from the connecting plate 300, and improving the convenience and efficiency of replacing the clamping block 500.

[0051] Furthermore, the driving member 400 is respectively connected to the screw holes 303 penetrated through the two connecting plates 300, and is threadedly connected to the two connecting plates 300. Since the rotation directions of the screw holes 303 of the two connecting plates 300 are opposite, the rotation of the driving member 400 can drive the two connecting plates 300 to close or separate, and then drive the two clamping blocks 500 to clamp or loosen the welding wire. The welding wire can be clamped or loosened through one action, which improves the convenience of clamping the welding wire.

[0052] In some preferred embodiments, the electronic product clamping mechanism 10 also includes a support block 700, which is located between the two supporting blocks 200 and fixedly connected to the connecting frame 100. The support block 700 is used to support the driving member 400, that is, the lower side of the driving member 400 is in contact with the support block 700, thereby improving the stability of the driving member 400, and further improving the stability of the connecting plate 300 and the clamping block 500, thereby improving the stability of the clamping position and improving the quality of welding.

[0053] In some preferred embodiments, a support groove 701 is opened on the upper side of the support block 700, and the support groove 701 is located on the upper side of the bearing block 200. The inner wall of the support groove 701 is connected to the driving member 400, so that the support groove 701 wraps the driving member 400, thereby increasing the supporting effect of the support block 700.

[0054] In some preferred embodiments, the driving member 400 includes a threaded sleeve 410 and a driving rod 420. The number of the threaded sleeves 410 is two. The two threaded sleeves 410 are respectively located in the screw holes 303 of the two connecting plates 300 and are respectively threadedly connected to the two connecting plates 300. Specifically, the outer side of the threaded sleeve 410 is provided with an external thread, and the external threads of the two threaded sleeves 410 have opposite rotation directions. The external thread of each threaded sleeve 410 is adapted to the corresponding screw hole 303 of the connecting plate 300. The threaded sleeve 410 is provided with a connecting hole, and the driving rod 420 is respectively penetrated through the connecting holes of the two threaded sleeves 410 and is respectively fixedly connected to the two threaded sleeves 410. In this embodiment, when the driving rod 420 is rotated, the driving rod 420 drives the two threaded sleeves 410 to rotate, so that each threaded sleeve 410 drives the corresponding connecting plate 300 and the clamping block 500 to move, thereby driving the two clamping blocks 500 to clamp or loosen.

[0055] In some preferred embodiments, the driving member 400 further includes a knob 430 , which is fixedly connected to one end of the driving rod 420 . The driving rod 420 is rotated by the knob 430 , thereby improving the convenience of rotating the driving rod 420 .

[0056] In some preferred embodiments, an anti-skid structure is formed on the outer side of the knob 430 to prevent the knob 430 from slipping when the knob 430 is turned.

[0057] In some preferred embodiments, the knob 430 is fixedly sleeved on one end of the driving rod 420 .

[0058] In some preferred embodiments, each clamping block 500 is provided with a limiting hole 501, and each ejector rod 600 is also located in the corresponding limiting hole 501 and connected to the corresponding clamping block 500, so that the ejector rod 600 also serves to limit the clamping block 500, thereby suppressing the problem of displacement of the clamping block 500 when clamping the welding wire, improving the stability of the clamping position, and thereby improving the welding quality.

[0059] Embodiment 2:

[0060] This embodiment provides a welding wire feeding device based on any of the above embodiments. Figure 6 .

[0061] The welding wire conveying device of this embodiment includes an unwinding mechanism 20, a guiding mechanism 30 and an electronic product clamping mechanism 10 which are arranged in sequence. The welding wire coil is sleeved on the unwinding shaft of the unwinding mechanism 20. The unwinding mechanism 20 is used to unwind the welding wire coil. The guiding mechanism 30 is provided with a guide hole for the welding wire to pass through so as to guide the welding wire. The welding wire passing through the guide hole is clamped between two clamping blocks 500.

[0062] The welding wire feeding device provided by the utility model, when the clamping block 500 is disassembled, the ejector rod 600 is rotated to make the ejector rod 600 move toward the clamping block 500. As the ejector rod 600 rotates, the ejector rod 600 will push the clamping block 500, so that the clamping block 500 is separated from the installation groove 302, thereby reducing the tightness of the connection between the clamping block 500 and the connecting plate 300, reducing the difficulty of removing the clamping block 500 from the connecting plate 300, and improving the convenience and efficiency of replacing the clamping block 500.

[0063] Furthermore, the driving member 400 is respectively connected to the screw holes 303 penetrated through the two connecting plates 300, and is threadedly connected to the two connecting plates 300. Since the rotation directions of the screw holes 303 of the two connecting plates 300 are opposite, the rotation of the driving member 400 can drive the two connecting plates 300 to close or separate, and then drive the two clamping blocks 500 to clamp or loosen the welding wire. The welding wire can be clamped or loosened through one action, which improves the convenience of clamping the welding wire.

[0067] In the welding equipment of the present invention, when the clamping block 500 is disassembled, the ejector rod 600 is rotated to move the ejector rod 600 toward the clamping block 500. As the ejector rod 600 rotates, the ejector rod 600 pushes the clamping block 500, so that the clamping block 500 is separated from the installation groove 302, thereby reducing the tightness of the connection between the clamping block 500 and the connecting plate 300, reducing the difficulty of removing the clamping block 500 from the connecting plate 300, and improving the convenience and efficiency of replacing the clamping block 500.

[0068] Furthermore, the driving member 400 is respectively connected to the screw holes 303 penetrated through the two connecting plates 300, and is threadedly connected to the two connecting plates 300. Since the rotation directions of the screw holes 303 of the two connecting plates 300 are opposite, the rotation of the driving member 400 can drive the two connecting plates 300 to close or separate, and then drive the two clamping blocks 500 to clamp or loosen the welding wire.
