Description

Technical Field

[0001] This utility model relates to a rotary multi-worker pad printing device, belonging to the technical field of pad printing equipment. Background Technology

[0002] Pad printing technology uses a silicone pad to transfer patterns from a steel plate to the surface of irregular workpieces, and is widely used in precision industries such as electronics, medical devices, switches, and toys. Pad printing is an indirect, concave-convex printing technology that has become a major method for printing and decorating various object surfaces.

[0003] Currently, many companies use single-worker pad printing machines (single squeegee + fixed printing head). Operators manually clamp workpieces onto the machine one by one for printing. When workpieces require multiple patterns on different surfaces, multiple single-worker pad printing machines are needed. Each machine requires at least one operator, making operation time-consuming, labor-intensive, and inefficient. Workpieces require multiple clamping attempts to complete processing, resulting in significant clamping errors and poor workpiece quality. Furthermore, the investment in equipment and labor costs makes them impractical. Additionally, existing single-worker pad printing machines generally lack adequate ventilation systems, preventing the timely removal of volatile ink during printing, which can affect the health of workers. While some large-scale pad printing equipment exists that effectively improves processing efficiency and quality, these are often complex in structure and have high investment costs, making them difficult for small and medium-sized enterprises to adopt. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rotary multi-tasking printing device to at least solve the problems mentioned in the background art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A rotary multi-workstation transfer printing device includes a base, a worktable on the top surface of the base, a rotary clamping plate rotatably connected to the worktable, a plurality of clamping mechanisms for fixing and flipping workpieces are evenly distributed around the rotary clamping plate, a top plate is provided on the top of the worktable, a plurality of transfer printing bodies are provided on the top plate and positioned opposite to the clamping mechanisms, and a PLC controller is provided on one side of the worktable, the PLC controller being electrically connected to the rotary clamping plate, the clamping mechanisms and the transfer printing bodies.

[0007] Furthermore, the clamping mechanism consists of at least 8 pieces evenly distributed around the edge of the circumferential rotary clamping plate, and at least 4 pieces of pad printing machine body are provided on the top plate opposite to the positions of the 4 clamping mechanisms. This divides the clamping mechanism into a clamping station and a pad printing station. The clamping station is used for the installation and removal of workpieces, while the pad printing station is used to complete the pad printing process of workpieces in sequence.

[0008] Furthermore, the rotary clamping plate includes a circular disc body disposed on the worktable surface, and the circular disc body is connected to a first drive motor disposed in the base.

[0009] Furthermore, the clamping mechanism includes a mounting frame fixed to the edge of the circular disc, the mounting frame having a flip plate, the flip plate being connected to a second drive motor located on one side of the mounting frame via a rotating shaft, and a clamping body being detachably connected to the flip plate.

[0010] Furthermore, the clamping body is adapted to the workpiece to be processed, and it can be configured with various shapes and specifications according to different workpieces.

[0011] Furthermore, a first detection mechanism is provided on the workbench for detecting whether there is a workpiece on the clamping mechanism. The first detection mechanism is arranged at the front of the first pad printing machine body near the pad printing station, and the first detection mechanism is connected to the PLC controller.

[0012] Furthermore, the workbench has openable glass windows on both sides and the back, and a dust extraction hole on the top plate, which is connected to the ventilation system through a ventilation duct.

[0013] Furthermore, the front of the workbench is an open working port, and a second detection mechanism is provided on the open working port to detect whether anyone is approaching during the working process. The second detection mechanism is connected to the PLC controller.

[0014] Furthermore, a third detection mechanism is installed on the top panel near each glass window to detect whether anyone has opened the window during the work process. The third detection mechanism is connected to the PLC controller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a simple structure, high ease of use, and good flexibility. Through the coordinated use of a rotary multi-station clamping mechanism and a pad printing machine body, it can complete multi-sided and multi-pattern pad printing of workpieces in a single clamping operation. Furthermore, it can achieve continuous automated batch processing of workpieces, resulting in high processing efficiency, good quality, and low processing costs. In addition, the glass window creates a relatively isolated area around the worktable, improving safety and allowing the ventilation system to promptly remove volatile ink from the work area, ensuring a comfortable working environment.

[0028] The rotary clamping plate 3 includes a circular plate body mounted on the workbench 2, and the circular plate body is connected to a first drive motor mounted in the base 1. The PLC controller 7 controls the rotation of the first drive motor, which in turn drives the circular plate body to rotate.
