Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen production and manufacturing, and more specifically, to an integrated ejector pin of a solder paste printer. Background Art

[0002] In the production process of LED modules, the printing effect of solder paste plays a key role in the product. Poor printing often causes problems such as yin and yang sides and ink color differences in the product, so it is of utmost importance to give full play to the role of solder paste printers. At present, in the field of LED display manufacturing, the most widely used types of ejectors for solder paste printers are long strip ejectors and columnar ejectors. Both types of ejectors are supported by a single individual reflow soldering fixture, and often shift in position during daily production, which does not play a practical supporting role, resulting in poor printing effect of PCB board modules.

[0003] The inventor believes that the ejector pins currently used in solder paste printers are all individual. Before production, the ejector pins need to be arranged one by one according to the standard, and during the production process, the position of a single ejector pin is often offset due to some uncertain factors, which directly leads to poor module printing effect, affecting production yield and product quality. Based on the above problems, we provide an integrated ejector pin for a solder paste printer.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides an integrated ejector pin for a solder paste printer.

[0006] The utility model provides an integrated ejector pin for a solder paste printer, which adopts the following technical solution:

[0007] An integrated ejector pin for a solder paste printer comprises a support base; a main frame fixedly arranged on the top of the support base; a pair of cross beams, both arranged in the main frame; a pair of longitudinal beams, both arranged in the main frame, and the cross beams and the longitudinal beams are arranged in a staggered manner; and a plurality of grooves, all arranged on the long side of the top of the main frame.

[0008] Preferably, a plurality of strong magnetic holes are provided on the top of the support base.

[0009] Preferably, a plurality of limiting strips are fixedly connected to the inner wall of the main frame, and slots are provided on both sides of the cross beam and the longitudinal beam, and the slots and the limiting strips can be plugged and assembled.

[0010] Preferably, the limiting strip is in a dovetail shape, and the slot is fully matched with the limiting strip.

[0011] Preferably, a notch is formed at the bottom of the cross beam, a notch is formed at the top of the longitudinal beam, and the cross beam is plugged into the longitudinal beam.

[0012] In summary, the utility model includes the following beneficial technical effects:

[0013] By using this device, the contact surface with the reflow soldering jig is larger, and the groove on the long side of the integrated ejector pin effectively avoids the buckle of the reflow soldering jig, so that the contact surfaces of the ejector pin and the reflow soldering jig are all tightly fitted, and multiple strong magnetic holes make it difficult for the main frame to shift. Strong magnetic holes are added to the bottom of the integrated ejector pin, so that the ejector pin is adsorbed on the internal platform of the printing press as a whole, which is not easy to shift and provides stable support for the reflow soldering jig. It is only necessary to match the diagonal corners of the integrated ejector pin with the reflow soldering jig up and down, and there is no need to match the single ejector pin one by one with different positions of the reflow soldering jig. The operation is simple and convenient.

[0014] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
