Description
Technical Field
The utility model relates to a screen printer for a filter.
Background
A filter press is a device that is specially used for screen printing in the filter manufacturing process. The utility model discloses an automatic loading and unloading device of a screen printer, and the specification of the publication is shown in figure 2, which clearly discloses a complete machine structure diagram of the filter printer, and the main structure of the filter printer can be clearly seen by combining the complete machine structure diagram, and the automatic loading and unloading device mainly comprises a frame, a material conveying module consisting of a conveyer belt, an index plate rotatably arranged on the frame, a silk screen module for printing the periphery of the filter, and a printing reinforcing mechanism for supporting the filter during printing, wherein a clamping jaw mechanism is arranged between the material conveying module and the index plate and used for clamping the filter from the material conveying module to the index plate module or clamping the filter from the index plate module to the material conveying module. The material transporting module sequentially transports the filter, the left clamping jaw mechanism clamps the filter to the index plate, the index plate rotates to sequentially transport the filter to the lower part of the silk screen module, the printing reinforcing mechanism supports the filter, the filter is convenient to print, after the printing is finished, the index plate brings the filter away from the silk screen module, and then the right clamping jaw mechanism clamps the filter to the material transporting module.
The specification of publication (CN 213737494U) discloses only one arm assembly 66, and the arm assembly 66 is mainly composed of an arm 661, an arm connecting plate 662, a second cylinder mount 64, a guide rod 663, and a second cylinder 65. The clamping arm assembly 66 controls the opening and closing of the clamping arm 661 through the second air cylinder 65 to clamp the filter, the action is slower, the production efficiency is low, and the high-speed production of the filter cannot be met. Most importantly, the clamping arm assembly does not have the function of quick change, if the clamping arm assembly needs to be replaced, more tools are needed to be used for disassembling the connecting points of the clamping arm assembly, and the operation is extremely complicated.
Further, as can be clearly seen from fig. 1 or 2 in combination with the specification of the publication (CN 213737494U), the front end of the material handling module (i.e., the left half of the drawing) is provided with two sets of partition discharging mechanisms for separating and sorting the filters on the conveyor belt so as to ensure that only one filter is advanced below the arm-clamping assembly at a time. However, the positioning between the filter and the clamping arm assembly is realized completely by means of the transportation belt, the positioning is inaccurate, and the center point of the filter with different specifications is difficult to ensure to correspond to the center of the clamping arm assembly, so that the clamping arm assembly cannot accurately clamp the filter.
Further, the chinese patent document with publication number CN213891730U discloses a printing reinforcing mechanism of a screen printer, which mainly comprises a workbench, a fixing component, a supporting component, a workbench lifting cylinder, an auxiliary reinforcing mechanism and the like, wherein the fixing component comprises a plurality of positioning seats, a guide rod, a supporting plate and rollers, the supporting component comprises a supporting rod, a cylinder mounting plate and an assembling plate, and the auxiliary reinforcing mechanism comprises a reinforcing disc, a supporting frame and a supporting rod. The fixing component in the printing reinforcing mechanism cannot be adjusted, and the angle or the transverse position cannot be adjusted according to actual conditions. It is known from the disclosure of paragraph 0009 in connection with this publication that the guide in the fixing assembly serves to ensure that the positioning seats are located on the same axis and are not used to adjust the position of the fixing assembly.
Further, the design of the auxiliary reinforcing mechanism in the printing reinforcing mechanism is unreasonable, and the reinforcing disc cannot move back and forth. As is clear from the description of paragraph 0013 and fig. 2 in connection with this publication (CN 213891730U), the "reinforcing disc abuts against the axial end face of the product under the action of the support rod". The auxiliary reinforcing mechanism is not designed with any mechanism for driving the reinforcing disc or the supporting rod to move transversely, but the reinforcing disc is kept against the end face of the filter, so that when the filter reaches the position of the reinforcing disc or is separated from the reinforcing disc, a large force is needed, the reinforcing disc can scrape the end part of the filter, and the filter is greatly damaged, so that the quality inspection of the filter is failed. Therefore, the auxiliary reinforcing mechanism is unreasonable in design and cannot meet the actual production requirements.
