Abstract

The invention provides a replacement device and a replacement method. The replacement device and the replacement method are used for replacing a laser scanning unit of a three-dimensional printer, and a side cover of the printer is hinged to one side of a bottom shell; the replacement device comprises a carrying table, a rack, a first wheel shaft, a second wheel shaft and a control pin; the carrying table is used for carrying the laser scanning unit and is provided with a fixing groove; the rack is arranged on the bottom shell and is provided with a first side and a second side; the first wheel shaft is arranged between the side cover and the first side of the rack; the second wheel shaft is meshed with the second side of the rack; the control pin is arranged on the second wheel shaft; after the side cover is opened, the side cover drives the first wheel shaft to roll, the first wheel shaft drives the rack to move in the first direction, the rack drives the second wheel shaft to roll, and the second wheel shaft drives the control pin to move; when the carrying table is located at a first position, the control pin is inserted into the fixing groove so that the carrying table can be fixed; when the carrying table is located at a second position, the control pin can not be inserted into the fixing groove. According to the replacement device and the replacement method, the carrying table is locked at the initial position, and thus the purpose that the laser scanning unit is replaced on the basis that other devices are not damaged is achieved.

Description

technical field

[0001] The invention relates to a replacement device and a replacement method, in particular to a replacement device and a replacement method capable of replacing a laser scanning unit of a three-dimensional printer. Background technique

[0002] At present, the laser scanning unit of the 3D printer is directly locked on the printer casing by screws. In order to facilitate replacement, the laser scanning unit needs to be designed as a pluggable type. When the laser scanning unit needs to be replaced, the carrying laser scanning unit needs to be The carrier of the scanning unit returns to the initial position. If there is no self-locking device to lock the carrier at the initial position, it is easy to damage the device that cooperates with the carrier during the replacement operation. Contents of the invention

[0003] In order to solve the above problems, the present invention proposes a replacement device and a replacement method. By locking the carrier a...
