Description

Technical Field

[0001] This invention relates to the field of embossing devices, specifically to a Braille embossing measuring device based on the buffer pressure method and its working method. Background Technology

[0002] For visually impaired individuals, the transmission of Braille information is of paramount importance; their needs must first and foremost be seen. Whether it's elevator floor buttons, product packaging labels with names and expiration dates, or hazard warnings in various locations—places where sighted people rely on written information—visually impaired individuals often have even greater needs. Take the seemingly simple act of taking medication as an example. If a visually impaired person feels unwell and needs a prescription, they often need to repeatedly confirm the medication and dosage with the doctor. Back home, most visually impaired individuals identify medications by the shape of the box or the pills themselves, or they may arrange the medications in an orderly fashion and memorize the types. However, over time, they may forget the characteristics of the medications or their usage instructions, leading to frequent instances of taking the wrong medication or the wrong dosage. Given that the vast majority of medications lack Braille labeling, medication safety for the visually impaired is clearly a significant issue.

[0003] More and more outer packaging boxes now use embossing to create Braille on paper, making it easier for visually impaired people to use the products. However, due to the limited toughness of the paper and improper processing, when the height of the Braille dots does not meet the national standard, the surface color of the Braille dots cracks. On the one hand, this significantly affects the aesthetics of the outer packaging and damages the product's brand influence. On the other hand, because the height of the Braille dots does not meet the national standard, the Braille dots are relatively flat, increasing the risk of misreading information for visually impaired people and indirectly endangering their health. Summary of the Invention

[0004] The purpose of this invention is to provide a Braille embossing measuring device and its working method based on the buffer pressure method, so as to solve the problem mentioned in the background art that the existing Braille embossing devices, when processing Braille on outer packaging paper boxes, have the problem of surface color cracking of Braille dots when the height of the Braille dots does not meet the national standard requirements due to the limited toughness of the paper and improper process operation.

[0013] Preferably, an inner load bottom groove is provided at the bottom position of both ends of the bearing steel plate, and an auxiliary roller is provided inside the inner load bottom groove. The auxiliary roller is movably connected to the bearing steel plate through a bearing and a connecting shaft, and the bearing steel plate is rolled and guided by the guide groove through the auxiliary roller.

[0014] Preferably, a laser alarm is provided at the front end of one of the guide frame plates, and the output end of the laser receiver is electrically connected to the input end of the laser alarm.

[0015] Preferably, both ends of the two guide frame plates are provided with end slots, the end slots are integral with the guide frame plates, and the end slots are connected to the guide grooves.

[0016] Preferably, a locking end plate is installed inside the end slot, and a handle groove is provided on the outer wall of the locking end plate. The handle groove and the locking end plate are an integral structure.

[0017] Preferably, the base steel plate and the movable steel plate are located on the same vertical line, and the dimensions of the base steel plate are equal to the dimensions of the movable steel plate.

[0018] Preferably, a support plate is provided on the outer wall of the other side of the embossing platform. The support plate and the embossing platform are an integral structure, and a collection box is placed on the upper end of the support plate.

[0019] Preferably, the operating method of the Braille embossing measurement device based on the buffer pressure method includes the following steps:

[0020] Step 1: The belt conveyor transports the paper to the position of the receiving board. The paper used for Braille processing is laid on the surface of the embossing mold on the supporting steel plate. One end of the guide frame plate is the feeding position, and the other end is the unloading position. During the feeding process, the clamping end plate of the feeding position is removed. During the unloading process, the clamping end plate of the unloading position is removed.

[0021] Step 2: Next, move the supporting steel plate between the two guide frame plates so that the supporting steel plate at the feeding position moves to the position where it overlaps with the base steel plate. The accuracy of the overlap between the base steel plate and the supporting steel plate is determined by the laser emitter and laser receiver. During the movement of the supporting steel plate, the auxiliary roller rolls inside the guide groove.

[0022] Step 3: After overlapping and aligning, press the power switch to supply power to the distribution box and the electromagnet plate. After the electromagnet plate is powered on, it generates magnetic force to attract the base steel plate and lock and fix the overlapping position.

[0023] Step 4: The electric hydraulic cylinder drives the movable steel plate to press down, so that the embossing steel plate matches and presses against the embossing mold. A buffer pad is added between the embossing steel plate and the paper to reduce the direct pressure on the paper from the embossing pressure.

[0024] Step 5: After pressing and pressing, turn off the power switch to separate the bearing steel plate from the base steel plate. Then push the bearing steel plate to the material feeding position and replace it with the bearing steel plate with paper laid in the feeding position.

[0025] Step Six: Finally, remove the embossed paper from the embossing mold, then remove the supporting steel plate from the guide frame, re-lay the paper, and put it back in the feeding position for later use.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention uses an electric hydraulic cylinder to drive a movable steel plate downwards, causing the embossing steel plate to match and press against the embossing mold. A buffer pad is added between the embossing steel plate and the paper to reduce the direct pressure exerted on the paper by the embossing pressure. The original Braille embossing process showed obvious color cracking when the Braille height reached 0.15mm, with a cracking rate of 50%. After the improvement, the Braille dot height can reach 0.22mm without color cracking, the average Braille dot height is 0.16-0.20mm, the minimum value is 0.14mm, and the dot height below 0.14mm does not exceed 1%. This overcomes the problem of surface color cracking of Braille dots when the height of the Braille dots does not meet the national standard requirements due to the limited toughness of the paper and improper process operation when processing Braille on outer packaging boxes.

[0028] 2. One end of the guide frame plate is the feeding position, and the other end is the unloading position. During the feeding process, remove the clamping end plate of the feeding position. During the unloading process, remove the clamping end plate of the unloading position. Push the bearing steel plate to the unloading position and replace it with the bearing steel plate with paper pre-laid on it in the feeding position. Remove the embossed paper from the embossing mold. Then remove the bearing steel plate from the guide frame plate, re-lay the paper, and put it back in the feeding position for later use.

[0029] 3.3. The laser measuring device is used to measure the matching accuracy between the bottom mold protrusion and the top copper plate to determine the appropriate production tolerance. It moves the bearing steel plate between the two guide frame plates so that the bearing steel plate at the feeding position is moved to the position overlapping with the base steel plate. The matching accuracy between the base steel plate and the bearing steel plate is measured by the laser emitter and laser receiver for reference during mass production. Attached Figure Description
