Description

The present invention relates to the printer field, and specifically to a printer mechanism in which a plurality of main units use a common platform.

Industrial printers, which are applied to large print media such as ceramics or glass, realize printing by spraying ink of each color on the print medium through the head by inkjet and then firing, and the printer heads are displaced from each other. A plurality of micropores are provided, ink is ejected through these micropores, and generally one head module is provided with a plurality of heads offset from each other, and the number of head modules is based on the demand for printing accuracy. The higher the accuracy requirement, the more head modules are required.In conventional printers, the number of modules of each model number is determined, and different printing needs are required in actual production. Printing with a reduced number of heads can be achieved by shielding unnecessary modules depending on the number of heads, but this requires users to purchase a printer with more multi-modules than their actual needs. Therefore, if the initial investment of production is increased and a printer with a small number of modules is adopted as the initial investment, it cannot be expanded, and when the precision requirement becomes high, it is necessary to purchase a multi-module printer, and it is necessary to purchase a multi-module printer. Increase investment.

In the prior art, modularized printers have been proposed to provide more purchasing solutions to users, the printers consisting of a plurality of inkjet print units that are independent of each other and can be freely combined. Users can purchase a printer consisting of an appropriate number of inkjet print units according to their actual needs, and if they need to be expanded, they can purchase an inkjet print unit of the same model number and assemble it with the original printer. Therefore, it provides the user with more purchasing options. However, in order to protect the head, it is generally necessary to install the head module last, and since the inkjet print unit is relatively independent, it is necessary to install each head module at the time of installation, and the actual printing needs at the time of printing. It is necessary to adjust the distance between each head and the print medium based on the above, which is relatively complicated and not only increases the workload, but also makes the distance between each head module and the print medium the same. Is difficult to guarantee. Therefore, it is necessary to improve the conventional technique.

The present invention provides a printer mechanism in which a plurality of bodies that are freely assembled and expandable, easy to assemble, and easy to operate utilize a common platform in order to overcome at least one of the drawbacks described in the prior art.

In order to solve the above-mentioned technical problems, the present invention employs the following technical solutions.

A plurality of independently independent head carriage systems are further included, the head carriage system is provided between the inkjet printing system and the transport platform, and each head carriage is connected to the main body one by one.

In the present invention, the heads can be made independent of the main body and all the heads can be combined to form one head carriage system, the overall mounting of the heads can be realized, and the heights of all the heads can be easily controlled. , Make the distance between each head and the printed circuit board the same, saving the time of installation and distance adjustment. Both the head carriage system and the inkjet printing system can realize modular assembly, users can purchase the same number of head carriages and bodies based on their actual needs, and need to be expanded later. Sometimes the printer can be expanded simply by purchasing the head carriage and main body of the same model number and connecting the head carriage and main body purchased in the previous term, and the user can realize the expansion of the printer with the limited investment in the early stage and the production demand in the latter term. If accuracy requirements are reduced without the inconsistency of expansion, printing with fewer heads can be achieved by shielding unnecessary modules based on different printing needs, or unnecessary body and head carriages. Can be removed, which allows free assembly and expansion of the printer, reduces assembly difficulty and saves assembly time. At the same time, if a single main unit fails, printing can be continued by replacing the failed main unit, avoiding delays in production progress due to maintenance, and one by one when performing machine maintenance. It may be replaced and maintained one by one, and it is possible to guarantee continuous operation while maintaining the machine.

Different batches of printed circuit boards because different material printed circuit boards have different requirements for the distance between the head and the printed circuit board surface, and different thickness printed circuit boards can cause changes in the distance between the head and the printed circuit board surface. It is necessary to adjust the height of the head again every time the head is replaced, and the head carriage system is provided with an easily adjustable elevating mechanism so that the height of the head can be easily adjusted. The head carriage system includes a support stand and a plurality of head carriages, the head carriage is provided with an elevating frame, and a plurality of mounting positions provided in parallel are provided on the front surface of the support stand.
