Description

Technical Field

[0001] The utility model relates to the field of automation technology, and more specifically, to an integrated LED chip removal and welding mechanism for LED light string production equipment. Background Art

[0002] At present, in the processing of LED light strings on the market, a nozzle is usually used to transfer the LED chips to the track fixture on the circular track, and then transport them to the spot welding station through the circular track. The material removal and spot welding processes cannot be completed at the same time, thus increasing the processing steps. In addition, the suction nozzle has a certain instability in sucking the LED chips, and it cannot ensure that the LED chips are placed smoothly on the welding point, thereby making the production efficiency and product quality cannot be guaranteed.

[0003] In response to the above problems, the utility model provides an integrated LED chip removal and welding mechanism for LED light string production equipment, which can directly and smoothly clamp the LED chip to the welding point and perform spot welding at the same time, reducing the processing steps and greatly improving work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an integrated LED chip taking and welding mechanism for LED light string production equipment, which can perform the two processes of taking and spot welding simultaneously, thereby greatly improving the production efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated LED chip picking and welding mechanism for LED light string production equipment, comprising a base, a circular track provided on the base, a plurality of clamping mechanisms provided on the circular track, the clamping mechanism being transmitted on the circular track, the clamping mechanism comprising a track clamp provided on the circular track, a welding point being formed between the two track clamps, a welding gun being provided below the welding point, a loading platform and a picking component moving back and forth between the loading platform and the welding point being provided on the base, the picking component comprising a cylinder clamp for clamping the LED chip and a driving device for driving the cylinder clamp to move back and forth, when the cylinder clamp clamps the LED chip from the loading platform and places it on the welding point, the welding gun performs spot welding at the same time.

[0006] The utility model is further configured as follows: the cylinder clamp includes a cylinder body, a rear end cover provided with a mounting seat, a front end cover provided with a clamping assembly, and a power assembly arranged in the cylinder body; the clamping assembly includes a clamping jaw slidingly connected to the front end cover and a horn clamp symmetrically installed on the outside of the clamping jaw; a rocker arm connector is provided between the clamping jaw and the piston rod; the rocker arm connector drives the clamping jaws to move closer to or away from each other; the rocker arm connector is rotatably connected to the cylinder body through a positioning pin.

[0007] The utility model is further configured as follows: the power assembly includes a cylinder barrel arranged in the cylinder body, an air inlet and an air outlet arranged in the cylinder body and connected to the cylinder barrel, and a piston and a piston rod arranged in the cylinder barrel; the piston is arranged at the end of the piston rod; two sealing rings are provided on the outer ring of the piston; a strong magnetic ring is provided between the two sealing rings; and a corresponding dust cover is provided on the position where the piston rod extends out of the cylinder body.

[0008] The utility model is further configured as follows: the front end cover is provided with a sliding groove adapted to the bottom of the clamping jaw, and a closely connected ball is provided between the bottom of the clamping jaw and the sliding groove.

[0009] The utility model is further configured such that when the clamping jaws are retracted and pressed together, a gap is left between the horn clamps detachably connected to the clamping jaws.

[0010] The utility model is further configured as follows: the mounting seat is a hollow cylindrical structure, the fixed end is inserted into the mounting seat, and is fixed by fastening screws provided on both sides of the hollow cylinder.

[0011] The beneficial effects of the utility model are:

[0012] 1. The pneumatic clamp on the base picks up the LED chip from the loading platform. When the drive unit moves the pneumatic clamp to the welding point, the welding gun located below the welding point simultaneously performs spot welding. This combines the two processes of clamping and spot welding, effectively improving production efficiency. Using the pneumatic clamp to pick up the LED chip allows for smooth placement into the welding point, improving product quality.

[0013] 2. The sliding grooves that match the front cover and the bottom of the clamping jaws are equipped with closely connected balls to reduce friction and make the clamping jaws move closer or farther away from each other more smoothly. When the clamping jaws are closed, there is still some gap, which is just enough to clamp the LED chip and the force between the clamps will not damage the LED chip.

[0014] 3. Two sealing rings are set on the outside of the piston. When the cylinder is filled with air, the compressed air is used as power to push the piston outward. The better sealing enables the piston to push the piston rod smoothly. A strong magnetic ring is set between the two sealing rings, which can absorb small steel balls on the outer wall of the cylinder. The movement trajectory of the small steel balls can be used to detect whether the cylinder is moving normally. A dust cover is set at the position where the piston rod extends out of the cylinder body to effectively prevent dust attached to the piston rod during operation from entering the cylinder body.

[0015] 4. The mounting base is a hollow cylindrical structure. The fixed end is inserted into the mounting base. By loosening the fastening screws on both sides of the hollow cylinder, the fixed end moves up and down in the mounting base to adjust to the appropriate position, and then tighten the screws.

[0021] Reference Figures 1-4 The embodiments of the present invention are further described.

[0022] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0023] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

When the cylinder clamp 19 places the LED chip into the welding point 16, the welding gun 17 performs spot welding at the same time, thereby effectively improving production efficiency. The LED chip can be clamped by the cylinder clamp 19 and placed in the welding point 16 stably, thereby improving the quality of the product.

When the clamping jaws 8 are closed, some gaps are left in the horn clamp 9, which can just clamp the LED chip and the force between the clamps will not damage the LED chip.

[0026] The cylinder clamp 19 includes a cylinder body 1, end covers arranged at both ends of the cylinder body 1, a piston 6 assembly and a cylinder barrel arranged in the cylinder body 1.

The rocker arm connector 10 is rotatably connected to the cylinder body 1 via a locating pin, providing a certain degree of positional protection. The mounting seat 21 is a hollow cylindrical structure, into which the fixed end is inserted. By loosening the fastening screws on both sides of the hollow cylinder, the fixed end is moved up and down within the mounting seat 21 to adjust to the appropriate position, and then the screws are tightened.
