Description

Technical Field

[0001] The invention relates to the technical field of invoice stamping machines, in particular to a fully automatic intelligent invoice stamping machine. Background Art

[0002] Seals are proof of identity and rights of government agencies, enterprises and institutions, and are also important tools for confirming the validity of documents. In the process of carrying out work, seals can be divided into three aspects: authoritative role, legal role, and symbolic role; document stamping is a common operation in business handling. Traditional stamping is done manually by staff. When there are fewer documents to be stamped, the manual stamping method can still be applied, but when a large number of documents need to be stamped, the manual stamping method cannot meet the needs of high-efficiency work due to its low efficiency; in the stamping process, it is necessary to confirm the stamping position before using the seal. Since the documents with stamps have the particularity of legal effect, a clear seal and an accurate seal position can become a legal certificate. At present, there are also related stamping equipment to replace manual stamping and improve stamping efficiency.

[0003] The existing technical solutions for automatic stamping equipment mainly fall into the following categories: 1. Electromagnetic automatic stamping equipment. It is mainly composed of a base, main and auxiliary gears, two gear slots, a rubber conveyor belt connecting the main and auxiliary gears, an electromagnet, a motor, a small robot arm, a robot arm bracket, two single-chip microcomputers that control the motor and the small robot arm respectively, two DC power supplies, a sliding stage, and related circuits. Single-chip microcomputer 1 is used to control the operation and stop of the motor, and single-chip microcomputer 2 is used to control the rise and fall of the robot arm through an electromagnet. The structure of this technical solution is relatively complex, and the stamping action is the adsorption reliability and strength of the electromagnet are not high.

[0004] 2. Mechanical crankshaft automatic stamping equipment. The motor screw is used to drive the screw to rotate, thereby driving the bracket equipped with a ball screw pair to slide on the slide bar, so that the stamping mechanism installed on the bracket can realize the structure of moving at any position on the plane, so that the stamping position can be accurately selected. In addition, the motor drives the crankshaft to rotate, and the crankshaft drives the connecting rod to move, thereby driving the slide bar to slide on the sliding bearing fixed on the fixed plate, thereby driving the seal to move up and down. The stamping action of this technical solution is the rotation of the crank, and the stamping height remains unchanged. It cannot work when stamping documents of different thicknesses.

[0005] 3. Pneumatic automatic stamping equipment. It includes a material platform, a support frame fixed on the material platform, a cylinder fixed on the support frame and a stamping assembly. The stamping assembly includes a connecting piece, a stamping head, a clamping piece and a fixing piece. One end face of the connecting piece is provided with an opening for accommodating the stamping head. The clamping piece is sleeved on the connecting piece. The fixing piece includes a top plate and two side plates extending outward from both ends of the top plate. Both side plates are fixedly connected to the clamping piece, and the telescopic end of the cylinder is fixedly connected to the top plate. When the material is placed on the material platform, the cylinder drives the stamping assembly to move downward and stamps the material. After the stamping is completed, the cylinder moves back, driving the stamping assembly to move upward and return to its position. Stamping technology is mainly used for stamping in industrial production, which requires compressed air. However, it is unrealistic to provide compressed air as power for daily office stamping.

[0006] Moreover, when the current stamping equipment is used to stamp thicker documents, the document will form an inclination due to its thickness. The stamping equipment drops vertically to use the seal, which will result in the seal being unclear and incomplete, affecting the effectiveness of the document; the stamping machine cannot achieve automatic seal refueling when executing the stamping command; and the amount of ink during use is insufficient, resulting in unsatisfactory stamping effect, affecting the stamping quality and efficiency.

[0007] At present, after the tax bureau issues an invoice, the second copy of the invoice needs to be stamped by the tax bureau. Due to the large number of invoices issued by the tax bureau, manual stamping wastes a lot of manpower and material resources, is inefficient, and the quality of the stamp is difficult to guarantee. The general stamping machines on the market basically only have a single stamping function and no recognition function. They cannot identify whether the position where the document needs to be stamped has been stamped before stamping, nor can they identify whether the invoice to be stamped belongs to the range of invoices allowed to be stamped. Manual recognition will make the operation process cumbersome and labor-intensive.

[0008] In addition, due to the large volume of invoices issued by the tax bureau, when the current stamping equipment is stamping thicker invoices, the document will be uneven due to different thicknesses, and the stamping equipment will fall down to stamp, resulting in unclear and incomplete stamps, affecting the effectiveness of the document;

[0009] When the stamping equipment executes the stamping command, it is unable to realize automatic stamp refueling; and the amount of ink during use is insufficient, resulting in unsatisfactory stamping effect, affecting the stamping quality and efficiency. Summary of the invention
