工作原理:将条码扫码部件安装在第一壳体内。当要对物品进行扫码时,先打开盒盖,将电池放入电池盒内,电池能够对第一壳体和第二壳体内的用电部件进行供电,随后将盒盖盖回。通过第一固定带和第二固定带将本发明固定在手上,如此能够灵活、方便的使用条码扫码设备对物品进行扫码。当扫码的物品较多要将移动物品时,摁下第一开关,第一开关能够启动第一电机使第一转轴顺时针转动。第一转轴顺时针转动卷筒随之顺时针转动,卷筒顺时针转动将遮挡帘放出。第一转轴顺时针转动第一皮带轮随之顺时针转动,第一皮带轮顺时针转动通过平皮带带动第二皮带轮是顺时针转动,第二皮带轮顺时针转动带动第二转轴顺时针转动,第二转轴顺时针转动绕线盘随之顺时针转动,绕线盘顺时针转动将拉绳收回使卡条向上移动,卡条向上移动拉动遮挡帘向上移动,遮挡帘向上移动将扫码视窗遮住,随后松开第一开关第一电机随之关闭。如此能够防止在移动物品时,读取物品的条码。当物品移动完成后要对物品进行扫码时,摁下第二开关,第二开关能够启动第一电机使第一转轴逆时针转动,如此能够使卷筒逆时针转动将遮挡帘卷回,使绕线盘逆时针转动将拉绳放出。随后松开第二开关第一电机随之关闭。Working principle: Install the barcode scanning component in the first housing. When scanning an item, first open the lid and put the battery into the battery box. The battery can power the electrical components in the first and second housings, and then close the lid back. The present invention is fixed on the hand through the first fixing strap and the second fixing strap, so that the barcode scanning device can be used flexibly and conveniently to scan items. When there are many items to be scanned and it is necessary to move the items, press the first switch, and the first switch can start the first motor to rotate the first rotating shaft clockwise. The first rotating shaft rotates clockwise and the drum rotates clockwise, and the drum rotates clockwise to release the shielding curtain. The first rotating shaft rotates clockwise and the first pulley rotates clockwise. The first pulley rotates clockwise and drives the second pulley to rotate clockwise through the flat belt. The second pulley rotates clockwise to drive the second rotating shaft to rotate clockwise. The second rotating shaft Rotate the reel clockwise and the reel will rotate clockwise. Rotate the reel clockwise to retract the drawstring and move the card strip upward. The card strip moves upward and pulls the shielding curtain to move upward. The shielding curtain moves upward to cover the scanning window. Then Release the first switch and the first motor will turn off. This prevents the item's barcode from being read while the item is being moved. When the object needs to be scanned after the object has been moved, press the second switch. The second switch can start the first motor to rotate the first shaft counterclockwise. This can cause the roller to rotate counterclockwise to roll back the blind curtain. Turn the reel counterclockwise to release the drawstring. Then release the second switch and the first motor will turn off.

因为还包括有滑轨、滑块和行程开关,第二壳体内的左右两侧均通过螺栓连接的方式竖直连接有滑轨,滑轨位于第一转轴和第二转轴之间,滑轨上设有与其配合的滑块,滑块与滑轨滑动配合,左侧滑块的右侧面通过螺栓连接的方式与卡条的左侧面相连接,右侧滑块的左侧面通过螺栓连接的方式与卡条的右侧面相连接,左侧滑轨右侧面的上下两侧均设置有行程开关,行程开关与第一电机之间有线路连接。绕线盘逆时针转动收回拉绳使卡条经滑块在滑轨上向上移动,卡条拉动遮挡帘向上移动,当左侧滑块向上移动至触碰上侧的行程开关时,上侧行程开关能够将电机关闭。卷筒顺时针转动将遮挡帘卷回,遮挡帘拉动卡条经滑块在滑轨上向下移动,当左滑块向下移动至触碰下侧的行程开关时,下侧的行程开关能够将电机关闭。如此能够使卡条和遮挡帘更加平稳的上下移动,能够防止卡条和遮挡帘左右晃动。Because it also includes a slide rail, a slide block and a travel switch, the left and right sides of the second housing are vertically connected with slide rails through bolt connections. The slide rails are located between the first rotating shaft and the second rotating shaft. It is equipped with a matching slide block. The slide block is slidingly matched with the slide rail. The right side of the left slide block is connected to the left side of the clip by bolts. The left side of the right slide block is connected by bolts. The way is connected with the right side of the clamping bar. There are limit switches on the upper and lower sides of the right side of the left slide rail. There is a circuit connection between the limit switch and the first motor. The winding reel rotates counterclockwise to retract the pull rope so that the clip bar moves upward on the slide rail through the slide block. The clip bar pulls the shield curtain to move upward. When the left slide block moves upward to touch the upper travel switch, the upper side stroke The switch turns the motor off. The roller rotates clockwise to roll back the shade, and the shade pulls the clip to move downward on the slide rail through the slider. When the left slider moves downward to touch the lower limit switch, the lower limit switch can Turn the motor off. This can make the clamping strip and the shielding curtain move up and down more smoothly, and prevent the clamping strip and the shielding curtain from shaking left and right.

因为还包括有LED灯珠、盒子、钢珠、高密度海绵和按钮,第二壳体前侧面上部的中间设置有LED灯珠,LED灯珠位于扫码视窗的上方,第二壳体后侧面上部的左侧连接有盒子,盒子位于第二转轴的上方,盒子内从下至上依次设置有钢珠、高密度海绵和按钮,按钮固定在盒子上,高密度海绵与盒子通过粘接连接的方式连接,钢珠放置在盒子内,电池盒分别与按钮和LED灯珠有线路连接。光线较暗时甩动本发明一下,使钢珠向上移动,钢珠向上移动推动高密度海绵向上移动并按下按钮,如此能够开启LED灯珠,LED灯珠能够对物品进行照明,从而能够提高扫码速度。高密度海绵能够对按钮进行保护,防止钢珠将按钮损坏。当不需要对物品进行照明时,再甩动本发明一下就可将LED灯珠关闭。Because it also includes LED lamp beads, boxes, steel balls, high-density sponges and buttons, an LED lamp bead is arranged in the middle of the upper part of the front side of the second housing. The LED lamp bead is located above the scanning window. The upper part of the rear side of the second housing There is a box connected to the left side of the box. The box is located above the second rotating shaft. There are steel balls, high-density sponge and buttons in the box from bottom to top. The button is fixed on the box. The high-density sponge and the box are connected by adhesive connection. The steel balls are placed in the box, and the battery box is connected to the button and LED lamp beads respectively. When the light is dark, shake the invention to make the steel balls move upward. The steel balls move upward to push the high-density sponge to move upward and press the button. This can turn on the LED lamp beads, which can illuminate the items, thereby improving code scanning. speed. High-density sponge can protect the buttons and prevent steel balls from damaging them. When the object does not need to be illuminated, the LED lamp bead can be turned off by shaking the present invention.

因为第一壳体的制作材料为不锈钢,不锈钢不易生锈,能够延长第一壳体的使用年限。Because the first housing is made of stainless steel, stainless steel is not easy to rust and can extend the service life of the first housing.

因为遮挡帘的制作材料为皮革,皮革柔软、透气、耐磨、强度高,能够延长遮挡帘的使用年限。Because the blinds are made of leather, which is soft, breathable, wear-resistant, and high in strength, it can extend the service life of the blinds.

因为第一电机为伺服电机,伺服电机能够更精准的控制其转速,使运行更加平稳。Because the first motor is a servo motor, the servo motor can control its speed more accurately, making the operation smoother.
