[0020] Example 1:

[0021] like Figures 1-3 As shown, an automatic soldering device for LED light boards includes a base 1, a gantry frame 2 slidably mounted on the top of the base 1, a support plate 3 at the center of the top of the gantry frame 2, a lifting device 4 fixedly mounted on the front end of the support plate 3, an automatic soldering gun 5 at the bottom of the lifting device 4, a driving device 6 on the top of the base 1, a clamping fixture 7 fixedly mounted on the top of the driving device 6, the driving device 6 driving the clamping fixture 7 to move back and forth relative to the base 1, a linear drive cylinder 8 fixedly mounted on the rear side of the support plate 3, the linear drive cylinder 8 fixedly mounted on the top of the gantry frame 2, the slider of the linear drive cylinder 8 fixedly connected to the support plate 3, an infrared ranging device 9 fixedly mounted on the bottom of the lifting device 4, a camera recognition device 10 fixedly mounted on the top of the gantry frame 2, visual positioning auxiliary structures 11 at the four corners of the top of the clamping fixture 7, and an automatic soldering gun 5 at the four corners of the bottom of the base 1. Equipped with buffer feet, the bottom of the lifting device 4 is fixedly installed with an air nozzle, one end of which is connected to an air pump via a hose. A waste collection box is provided on one side of the gantry frame 2. The lifting device 4 includes a drive cylinder, a support plate, and a limit plate. The support plate is vertically installed on the front side of the mounting plate, and the limit plate is bolted to the bottom of the support plate. The drive cylinder is fixedly installed on the front end of the support plate. The bottom end of the support plate is provided with multiple threaded holes that pass through from front to back, and the rear end of the limit plate is provided with screw holes corresponding to the threaded holes. Because this device is mainly used for welding LED light boards, the lowest point of the stroke is limited. Depending on the thickness of the LED light board, the required stroke is a few relatively fixed values. In order to avoid the decrease in the accuracy of the drive cylinder due to long-term operation, the end stroke of the drive cylinder is controlled by the position of the limit plate, which can greatly increase the positioning accuracy of the lifting cylinder and ensure the long-term operation of the drive cylinder.

[0022] Specific implementation process: The gantry can move back and forth, and the clamping fixture can also move back and forth under the drive of the drive device. Under the same size, the stroke of this device is more than 80% greater than that of traditional welding devices, so the amount of material that can be clamped at one time is 1.5-2 times that of traditional equipment. It saves the positioning time required for each clamping, thus greatly improving welding efficiency.

[0023] In the embodiments disclosed in the present application, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, "connecting" can be fixed connection, or detachable connection, or integrally connected; "connecting" can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments disclosed in the present application can be understood according to the specific circumstances.

[0024] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the present application, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
