Description

Technical Field

[0001] The utility model belongs to the technical field of printing driver boards, in particular to a printing driver board docking structure free of interface boards and adapter cables. Background Art

[0002] The printer driver board usually refers to the circuit board inside the printer. It is one of the core components of the printer hardware. The printer driver board is responsible for controlling various operations of the printer, including print speed, print quality, paper handling, etc.

[0003] In the existing technology, most of the control cards and interface boards are stacked to control the inkjet print head. The hardware design of the control card remains basically unchanged. The interface board needs to be redesigned according to the different digital technology industrial control inkjet print heads or nozzle models to connect to the nozzles of that model and drive the nozzles to print.

[0004] This structure takes up too much space, increasing production costs. Furthermore, with the existing print control solution, it's difficult to quickly and easily conduct preliminary testing of new printhead models before they're released to the market. This testing can only be done after a new interface board is redesigned for the new printhead. This lengthens the cycle from control board design to prototype production, lengthening the process from printhead testing to mass production. Furthermore, the use of multiple interface boards to connect various printhead models increases hardware revisions, production steps, and procurement costs.

[0005] Therefore, in order to solve the above problems, a printing driver board docking structure without an interface board and a switching cable is proposed. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a printing driver board docking structure that is free of interface boards and adapter cables. It has higher scalability, is easy to assemble, has a compact structure, is easy to maintain, and makes it easy to iterate new products with control card components, shortens the testing cycle, and finally improves production efficiency and reduces production costs. It solves the problems of structural stacking, long testing cycle, complex use, low production efficiency, and high cost.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a printing driver board docking structure that is free of interface boards and adapter cables, comprising a control card body, a first cylindrical hole being provided on the surface of the control card body, a plurality of second cylindrical holes being provided on the surface of the control card body, a first cylindrical pin being clamped inside the first cylindrical hole, a connector body being fixedly provided on the top surface of the first cylindrical pin, a second cylindrical pin being fixedly provided on the side of the bottom surface of the connector body, a third cylindrical pin being fixedly provided on the side of the bottom surface of the connector body, a fourth cylindrical pin being fixedly provided on the side of the bottom surface of the connector body, and the plurality of second cylindrical holes being clamped with the second cylindrical pin, the third cylindrical pin and the fourth cylindrical pin.

[0008] Preferably, a first pin is fixedly provided on one side of the connector body, the first pin is fixedly connected to the nozzle end connector, and the first pin is fitted with the control card body.

[0009] Preferably, a second pin is fixedly connected to the other side of the connector body, the second pin is fixedly connected to another nozzle end connector, and the second pin is in contact with the control card body.

[0010] Preferably, a third pin is fixedly connected to the other side of the connector body, the third pin is fixedly connected to another nozzle end connector, and the third pin is in contact with the control card body.

[0011] Preferably, a fourth pin is fixedly connected to the other side of the connector body, the fourth pin is fixedly connected to another nozzle end connector, and the fourth pin is in contact with the control card body.

[0012] Preferably, the diameter of the first cylindrical pin is 1.1 mm, the diameter of the second cylindrical pin is 1.6 mm, and the diameters of the second cylindrical pin, the third cylindrical pin, and the fourth cylindrical pin are the same.

[0013] Preferably, a measurement interface is provided on the top of the control card body, a mounting hole is provided on the bottom of the control card body, and a main control integrated circuit is fixedly provided on the surface of the control card body.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model controls the first cylindrical hole provided on the surface of the card body to be plugged into the first cylindrical pin provided on the bottom surface of the fourth cylindrical pin, and then the plurality of second cylindrical holes provided on the surface of the card body are plugged into the second cylindrical pin, the third cylindrical pin, and the fourth cylindrical pin provided on the bottom surface of the first cylindrical pin one by one, thereby completing the installation of the first cylindrical pin. Then, one of the nozzle end connectors is connected to the first pin, and the other nozzle end connector is selectively connected to the second pin, the third pin, and the fourth pin according to its own model, so as to adapt to its own model. The utility model can conveniently and quickly test the inkjet printing effect of a certain model of nozzle by only changing the control card connector and the drive signal selection circuit, instead of redesigning the drive board card before performing the nozzle printing test, thereby greatly reducing the workload of designers and significantly shortening the new product development cycle.

[0016] Furthermore, because a single control card assembly lacks interface boards or other stacked boards, its overall structure is simple, expandable, easy to assemble and disassemble, and maintain, resulting in higher efficiency and lower overall costs during mass production. This also speeds up testing and allows for rapid transitions to new product introductions, simplifying production testing and significantly improving production efficiency.
