Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and specifically to a soft connection structure for balancing errors. Background Technology

[0002] Traditionally, the printhead and the bellows-shaped sheet metal frame are rigidly connected by screws. Due to the rigid constraints of this connection, machining tolerances and assembly deviations are directly transmitted to the printhead, causing movement jamming, deterioration of printing accuracy, and difficulty in ensuring performance consistency between devices. Therefore, a new connection structure is urgently needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a flexible connection structure that balances errors, utilizing the vertical support force and multi-directional swing freedom provided by the fisheye bearing to solve problems such as motion jamming, deterioration of printing accuracy, and difficulty in ensuring equipment consistency in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a soft connection structure for balancing errors is provided, including: a print head and a mounting frame. The print head is slidably connected to the mounting frame through an X-axis moving component and a Y-axis moving component. The two sides of the print head are respectively hinged to the Y-axis moving component through bearing components.

[0005] The bearing assembly includes a fisheye bearing, which is mounted on the Y-axis moving assembly. The ball bearing of the fisheye bearing is connected to the print head via a connecting rod.

[0006] Furthermore, the X-axis moving component includes a set of X-axis linear guides, which are respectively arranged on both sides of the mounting frame in the X-axis direction. A first slider is movably connected to the X-axis linear guide, and the Y-axis moving component is slidably connected to the X-axis linear guide through the first slider.

[0007] Furthermore, the Y-axis moving component includes a set of Y-axis linear guides. The two ends of the Y-axis linear guides are fixed by connecting plates. The two ends of the Y-axis linear guides are slidably connected to the X-axis linear guides by first sliders. A second slider is slidably connected to the Y-axis linear guides, and a fisheye bearing is set on the second slider.

[0008] Furthermore, the bottom of the fisheye bearing is fixedly connected to the second slider.

[0009] Furthermore, one end of the connecting rod is fixedly connected to the print head, and the other end of the connecting rod is hinged to the fisheye bearing.

[0010] Furthermore, the inner diameter of the ball bearing in the fisheye bearing is the same as the outer diameter of the connecting rod.

[0011] Furthermore, accordion covers are installed between the mounting frames.

[0012] This utility model has the following beneficial effects:

[0013] Traditional printheads and frames are rigidly connected with screws, resulting in issues such as motion jamming, degraded printing accuracy, and difficulty in ensuring equipment consistency. This solution, however, hinges the printhead and the second slider in the Y-axis moving assembly using a fisheye bearing. This fisheye bearing provides vertical support, ensuring printhead stability. Furthermore, by utilizing its multi-directional swing freedom, it automatically compensates for motion interference caused by machining / assembly errors (such as guide rail parallelism deviations and frame deformation), eliminating motion jamming and fundamentally improving printing accuracy and equipment consistency, thus resolving related problems in existing technologies.

Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1 to 4 As shown, this embodiment provides a soft connection structure for balancing errors, including: a print head 10 and a mounting frame 20. The print head 10 is slidably connected to the mounting frame 20 via an X-axis moving assembly 30 and a Y-axis moving assembly 40. Both sides of the print head 10 are hinged to the Y-axis moving assembly 40 via bearing assemblies 50. The bearing assembly 50 includes a fisheye bearing 51, which is disposed on the Y-axis moving assembly 40. The ball bearing of the fisheye bearing 51 is connected to the print head 10 via a connecting rod 52.

[0021] In this embodiment, the X-axis moving component 30 includes a set of X-axis linear guides 31. The X-axis linear guides 31 are respectively disposed on both sides of the mounting frame 20 in the X-axis direction. A first slider 32 is movably connected to the X-axis linear guide 31. The Y-axis moving component 40 is slidably connected to the X-axis linear guide 31 through the first slider 32.

[0022] The Y-axis moving assembly 40 includes a set of Y-axis linear guides 41. The two ends of the Y-axis linear guides 41 are fixed by connecting plates 42. The two ends of the Y-axis linear guides 41 are slidably connected to the X-axis linear guides 31 by first sliders 32. A second slider 43 is slidably connected to the Y-axis linear guides 41, and a fisheye bearing 51 is disposed on the second slider 43.

[0023] In this embodiment, one end of the connecting rod 52 is fixedly connected to the print head 10, and the other end of the connecting rod 52 is hinged to the fisheye bearing 51; at the same time, the bottom of the fisheye bearing 51 is fixedly connected to the second slider 43. The inner diameter of the rod ball is the same as the outer diameter of the connecting rod 52; an accordion cover 60 is provided between the mounting frames 20.

[0024] In use, the print head 10 and the second slider 43 in the Y-axis moving assembly 40 are hinged together by a fisheye bearing 51. This fisheye bearing 51 provides vertical support to ensure the stability of the print head 10's posture. Furthermore, by utilizing the multi-directional swing freedom of the fisheye bearing 51, it can automatically compensate for motion interference caused by machining / assembly errors (such as guide rail parallelism deviation, frame deformation, etc.), eliminating motion jamming and fundamentally improving printing accuracy and equipment consistency. This solves problems such as motion jamming, deteriorated printing accuracy, and difficulty in guaranteeing equipment consistency in existing technologies.
