Description

Technical field The present description discloses an exchange unit and a printing device. State of the art In related technology, for example in a printing device that performs a printing process with viscous liquids on a printing target such as a plate using a screen mask, a printing device is proposed in which the receiving frame that holds the screen mask is raised and lowered between an exchange position and a retractable position to automatically exchange the screen mask (see, for example, patent literature 1). In this printing device, the receiving frame is retracted into a space in the lower part of a housing as the retractable position, thereby achieving further miniaturization. Citation list Patent literature Patent literature 1: WO 2022/224430 Summary of the invention Technical task However, the automatic exchange of non-screen mask consumables, such as solder paste reservoirs, screen mask cleaning elements, or similar items, has not been sufficiently investigated in the printing device described above. If consumable exchange is delayed in the printing device, the efficiency of a printing operation can decrease. Furthermore, sufficient space must be provided within the printing device to accommodate consumables. Therefore, the challenge for this printing device lies in further improving both the efficiency of the work and space efficiency during consumable exchange. The present disclosure was prepared with this problem in mind and has as its main objective to provide an exchange unit and a printing device with which the work efficiency and space efficiency can be further improved when exchanging an element used in the printing device. Solution to the problem An exchange unit and a pressure device disclosed in the present description use the following means to achieve the main objective described above. An exchange unit of the present disclosure is an exchange unit for use in a printing device for carrying out a printing process with a viscous liquid on a target object using a screen mask and comprises at least one of the following devices: a storage element exchange device comprising a storage element placement section located and configured on the upper part of a rack unit adjacent to a housing of the printing device to place a storage element containing the viscous liquid, and a storage element movement section configured to move the storage element between the storage element placement section and a storage element opening section of the printing device; and a cleaning element exchange device comprising a cleaning element placement section located and configured on the upper part of the rack unit adjacent to the housing of the printing device to place a cleaning element configured to clean the screen mask, and a cleaning element movement section configured to move the cleaning element between the cleaning element placement section and a cleaning element opening section of the printing device. This exchange unit can position a storage element that holds viscous liquid next to a housing using a rack unit. Furthermore, the exchange unit can automatically replace the positioned storage element via a storage element movement section. Similarly, the exchange unit can position a cleaning element that cleans a screen mask next to a housing using a rack unit. Additionally, the exchange unit can automatically replace the positioned cleaning element via a cleaning element movement section. Therefore, this exchange unit further improves both labor and space efficiency when replacing an element for use in a printing device.
