Description

Technical Field

[0001] This invention relates to the field of cash register maintenance technology, specifically to an automated cash register maintenance device. Background Technology

[0002] Cash registers are a product of the combination of microelectronics technology development and modern commodity circulation management concepts and technologies. Commercial electronic cash registers are one of the essential basic electronic devices for modern and automated business management. In daily use, cash registers need to be maintained regularly to ensure that they can be used normally.

[0003] When maintaining a cash register, in addition to cleaning the display screen, it is also necessary to clean and charge the barcode scanner and other supporting equipment. Currently, cash register maintenance is usually done manually by cashiers, and the maintenance is mostly done in steps, and cashiering cannot be performed during the operation.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an automated maintenance device for cash registers. Summary of the Invention

[0005] The purpose of this invention is to provide an automated maintenance device for cash registers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated maintenance device for cash registers, comprising a chassis and a placement assembly. The placement assembly is located on the right side of the chassis. The placement assembly includes a base, a placement groove, an arc groove, a sliding cavity, a contact point, a pressure spring, a placement frame, a connector, a pressure rod, a lifting groove, a sliding cavity, a shaft, and a cleaning wheel. The base is fixedly connected to the right side of the chassis, and a placement groove is provided at the front right side of the base. An arc groove is provided behind the upper part of the placement groove. A sliding cavity is provided below the placement groove, and a contact point is fixedly connected inside the sliding cavity. A pressure spring is fixedly connected inside the placement groove, and a placement frame is fixedly connected to the upper end of the pressure spring. A connector is fixedly connected inside the placement frame, and a pressure rod is fixedly connected to the lower part of the placement frame. A lifting groove is provided in the middle of the arc groove, and sliding grooves are symmetrically provided on both sides of the arc groove. A shaft is slidably connected inside the sliding grooves, and a cleaning wheel is fixedly connected to the middle of the shaft.

[0007] Furthermore, the placement assembly also includes a guide wheel, a top rod, and a pull rope. The guide wheel is rotatably connected inside the lifting groove, and the top rod is slidably connected inside the lifting groove. The lower end of the top rod is fixedly connected to the pull rope.

[0008] Furthermore, the placement frame is elastically connected to the placement groove via a pressure spring, the pressure rod is slidably connected to the sliding cavity, and the other end of the pull rope passes over the guide wheel and is fixedly connected to the pressure rod.

[0009] Furthermore, the placement assembly also includes a transmission cavity, a transmission wheel, a drive wheel, and a motor. The base has a transmission cavity on the left side, a transmission wheel on the upper part of the transmission cavity, a drive wheel rotatably connected to the lower part of the transmission cavity, and a motor fixedly connected to the right side of the drive wheel.

[0010] Furthermore, the transmission wheel is connected to the drive wheel via a belt, and the end of the shaft passes through a groove and is fixedly connected to the transmission wheel. The motor is electrically connected to the contacts via internal wiring.

[0011] Furthermore, a bottom frame is fixedly connected to the left side of the chassis, and a slide rail is provided at the front of the bottom frame. A reciprocating screw is rotatably connected inside the slide rail, and a sliding plate is threadedly connected to the left side of the reciprocating screw.

[0012] Furthermore, a bushing is fitted onto the right end of the reciprocating screw, and symmetrical slots are provided on the inner side of the bushing. A locking block is slidably connected in the slot, and the locking block is fixedly connected to the reciprocating screw. The bushing is fixedly connected to the drive wheel.

[0013] Furthermore, a baffle is fixedly connected to the rear end of the upper surface of the bottom frame, and a stop block is symmetrically arranged in front of the baffle. A lower frame is arranged between the baffle and the stop block, and a tension spring is fixedly connected to the upper end of the lower frame.

[0014] Furthermore, an upper frame is fixedly connected above the tension spring, and a sliding rod is fixedly connected to both the lower frame and the front of the upper frame. An upper cleaning brush is slidably connected to the sliding rod of the upper frame, and a lower cleaning brush is slidably connected below the upper cleaning brush. A sleeve is provided at the lower end of the lower cleaning brush.

[0015] Furthermore, the lower cleaning brush is rotatably connected to the sleeve plate via a sliding rod, and both the lower cleaning brush and the sleeve plate are slidably connected to the sliding rod. The sleeve plate is fitted onto the upper part of the slide plate.

[0016] This invention provides an automated maintenance device for cash registers, which has the following advantages: during installation, it can be adapted to displays of different sizes, and when the cash register is not in use, it can automatically maintain the display screen and barcode scanner of the cash register, thereby ensuring the normal use of the cash register. When the cash register is in use, the maintenance process can be automatically interrupted to avoid hindering the cash register process.

[0017] When not in use, the barcode scanner can be inserted into the placement slot, and its charging end can be inserted into the placement frame. The connector can then be inserted into the barcode scanner's charging port. Under the weight of the barcode scanner, the placement frame compresses the pressure spring and drives the pressure rod to slide downwards within the sliding cavity. As the pressure rod moves downwards, it pulls the pull rope. Under the action of the guide wheel, the pull rope pulls the top rod upwards within the lifting slot, thereby pushing the cleaning wheel to move within the arc groove through its inclined surface. The cleaning wheel can drive the transmission wheel to move within the transmission cavity via the shaft, while the sliding groove can restrict the cleaning wheel through the shaft to prevent the cleaning wheel from tilting. When the placement frame is fully lowered, the cleaning wheel part enters the placement slot and engages with the barcode scanner. When the scanner head contacts the contact point, the pressure rod engages with the contact point, allowing the connector to charge the barcode scanner and simultaneously power the motor. The motor then drives the transmission wheel to rotate via the drive wheel, which in turn drives the cleaning wheel to rotate within the arc groove, cleaning the scanner head. When the barcode scanner is removed to scan a product, the placement frame springs back under the pressure spring, pulling the pressure rod away from the contact point and disconnecting the motor, thus ending the maintenance process. The top rod also falls back under gravity, allowing the cleaning wheel to slide to the lower end of the arc groove, preventing it from obstructing the removal and placement of the barcode scanner. In summary, the barcode scanner can be automatically cleaned and charged when not in use, and the maintenance process can be automatically terminated when in use.

[0018] 2. During installation, this invention simply requires lifting the upper and lower frames from the bottom frame and pulling them to allow the lower frame to slide on the upper frame while pulling the tension spring rope. Then, the upper and lower frames are placed outside the display screen. Releasing the upper and lower frames causes the tension spring to spring back, allowing the display screen frame to snap into the grooves on the inner sides of the upper and lower frames, thus fixing them to the display screen. The elasticity of the tension spring allows the upper and lower frames to be installed on display screens of different sizes, improving the applicability of the device. When the upper and lower frames are pulled, the upper and lower frames can slide synchronously with the upper and lower cleaning brushes via the sliding rod. The limiting block fixed inside the upper cleaning brush can work with the limiting grooves on both sides of the lower cleaning brush to restrict the lower cleaning brush and prevent it from falling off the upper cleaning brush. When not installed, the lower frame can be placed between the baffle and the block to restrict the lower frame and prevent it from tipping over. In summary, during installation, it can be adapted to displays of different sizes, improving the applicability of the device.

[0019] 3. In this invention, when installing the upper and lower frames, the lower frame can use a sliding rod to pull the sleeve plate off the slide plate, allowing the lower cleaning brush to remain connected to the slide plate via the sleeve plate. When maintaining the barcode scanner, the drive wheel can drive the bushing to rotate synchronously, causing the bushing to drive the reciprocating screw to rotate within the slide rail via the slot and block, thereby causing the slide plate to move reciprocally left and right within the slide rail. This, in turn, uses the sleeve plate to drive the lower and upper cleaning brushes to clean the display screen, removing surface dust. When the sleeve plate, upper cleaning brush, and lower cleaning brush move, the sliding rod can restrict their movement, thus limiting the slide plate and preventing it from tilting during movement. During use, if... When adjusting the tilt of the display screen, the sleeve plate and lower cleaning brush can rotate on the slide rod, so that the slide plate and sleeve plate can always remain vertical, while the lower cleaning brush and upper cleaning brush can remain parallel to the display screen. After the motor stops running, the bushing can drive the reciprocating screw to continue rotating several times under the action of inertia, so that the slide plate drives the lower cleaning brush and upper cleaning brush to approach the edge of the display screen through the sleeve plate, so as to prevent the lower cleaning brush and upper cleaning brush from blocking the display screen. If it is not possible to reach the edge of the display screen, it can also be manually moved to the edge to avoid obstructing the cashier operation. In summary, it can automatically clean the display screen when not in use, and avoids obstructing the cashier operation when in use. Attached Figure Description

[0029] Please see Figures 1 to 8 The present invention provides a technical solution: an automated maintenance device for cash registers, comprising a chassis 1 and a placement component 2. The placement component 2 is disposed on the right side of the chassis 1. The placement component 2 includes a base 201, a placement groove 202, an arc groove 203, a sliding cavity 204, a contact point 205, a pressure spring 206, a placement frame 207, a connector 208, a pressure rod 209, a lifting groove 210, a sliding groove 211, a shaft 212, and a cleaning wheel 213. The base 201 is fixedly connected to the right side of the chassis 1, and the placement groove 202 is provided on the front right side of the base 201. An arc groove is provided at the rear upper part of the placement groove 202. 203. A sliding cavity 204 is provided below the placement groove 202, and a contact 205 is fixedly connected inside the sliding cavity 204. A pressure spring 206 is fixedly connected inside the placement groove 202, and a placement frame 207 is fixedly connected to the upper end of the pressure spring 206. A connector 208 is fixedly connected inside the placement frame 207, and a pressure rod 209 is fixedly connected below the placement frame 207. A lifting groove 210 is provided in the middle of the arc groove 203, and sliding grooves 211 are symmetrically arranged on both sides of the arc groove 203. A shaft 212 is slidably connected inside the sliding groove 211, and a cleaning wheel 213 is fixedly connected to the middle of the shaft 212.

[0030] Please see Figures 1 to 4The placement assembly 2 also includes a guide wheel 214, a top rod 215, and a pull rope 216. The guide wheel 214 is rotatably connected inside the lifting groove 210, and the top rod 215 is slidably connected inside the lifting groove 210. The lower end of the top rod 215 is fixedly connected to the pull rope 216. The placement frame 207 is elastically connected to the placement groove 202 via a pressure spring 206. The pressure rod 209 is slidably connected to the sliding cavity 204, and the other end of the pull rope 216 passes over the guide wheel 214 and is fixedly connected to the pressure rod 209. The placement assembly 2 also includes a transmission mechanism. The base 201 has a transmission cavity 217, a transmission wheel 218, a drive wheel 219, and a motor 220. The left side of the base 201 has a transmission cavity 217, and the upper part of the transmission cavity 217 has a transmission wheel 218. The lower part of the transmission cavity 217 is rotatably connected to the drive wheel 219, and the right side of the drive wheel 219 is fixedly connected to the motor 220. The transmission wheel 218 is connected to the drive wheel 219 by a belt, and the end of the shaft 212 passes through the slide groove 211 and is fixedly connected to the transmission wheel 218. The motor 220 is electrically connected to the contact 205 through internal wiring.

[0031] The specific operation is as follows: When not in use, the barcode scanner can be inserted into the placement slot 202, and its charging end can be inserted into the placement frame 207. The connector 208 can then be inserted into the charging port of the barcode scanner. Under the gravity of the barcode scanner, the placement frame 207 can compress the pressure spring 206 and drive the pressure rod 209 to slide downward in the sliding cavity 204. During the downward movement of the pressure rod 209, it can pull the pull rope 216. Under the action of the guide wheel 214, the pull rope 216 can pull the top rod 215 to rise in the lifting groove 210, thereby pushing the cleaning wheel 213 to move in the arc groove 203 through its own inclined surface. The cleaning wheel 213 can drive the transmission wheel 218 to move in the transmission cavity 217 through the shaft 212, while the sliding groove 211 can restrict the cleaning wheel 213 through the shaft 212 to prevent the cleaning wheel 213 from tilting. When the placement frame 207 is completely lowered, the cleaning wheel 213 partially enters the groove. The barcode scanner is placed in the placement slot 202 and comes into contact with the scanning head of the barcode scanner. At this time, the pressure rod 209 contacts the contact point 205, allowing the connector 208 to charge the barcode scanner and simultaneously powering the motor 220. The motor 220 then drives the transmission wheel 218 to rotate via the drive wheel 219, which in turn drives the cleaning wheel 213 to rotate within the arc groove 203 via the shaft 212, cleaning the scanning head. When the barcode scanner is removed to scan the product, the placement frame 207 can spring back under the action of the pressure spring 206, pulling the pressure rod 209 away from the contact point 205, thus cutting off the power to the motor 220 and terminating the maintenance process. The top rod 215 can also fall back under the action of gravity, allowing the cleaning wheel 213 to slide to the lower end of the arc groove 203, preventing the cleaning wheel 213 from obstructing the removal and placement of the barcode scanner. In summary, the barcode scanner can be automatically cleaned and charged when not in use, and the maintenance process can be automatically terminated when in use.

[0032] Please see Figure 1 and Figures 5 to 8 A base frame 3 is fixedly connected to the left side of the chassis 1, and a slide rail 4 is provided at the front of the base frame 3. A reciprocating screw 5 is rotatably connected inside the slide rail 4, and a sliding plate 6 is threadedly connected to the left side of the reciprocating screw 5. A bushing 7 is sleeved on the right end of the reciprocating screw 5, and a slot 8 is symmetrically provided inside the bushing 7. A locking block 9 is slidably connected in the slot 8, and the locking block 9 is fixedly connected to the reciprocating screw 5. The bushing 7 is fixedly connected to the drive wheel 219. A baffle 10 is fixedly connected to the rear end of the upper surface of the base frame 3, and a stop block 11 is symmetrically arranged in front of the baffle 10. Between the baffle 10 and the stop block 11 A lower frame 12 is provided, and a tension spring 13 is fixedly connected to the upper end of the lower frame 12. An upper frame 14 is fixedly connected above the tension spring 13. A sliding rod 15 is fixedly connected to the front of both the lower frame 12 and the upper frame 14. An upper cleaning brush 16 is slidably connected to the sliding rod 15 of the upper frame 14, and a lower cleaning brush 17 is slidably connected below the upper cleaning brush 16. A sleeve plate 18 is provided at the lower end of the lower cleaning brush 17. The lower cleaning brush 17 is rotatably connected to the sleeve plate 18 through the sliding rod 15. Both the lower cleaning brush 17 and the sleeve plate 18 are slidably connected to the sliding rod 15. The sleeve plate 18 is sleeved on the upper part of the slide plate 6.

[0033] The specific operation is as follows: During installation, simply lift the upper frame 14 and lower frame 12 from the bottom frame 3, and pull the upper frame 14 and lower frame 12 so that the lower frame 12 slides on the upper frame 14. Then, pull the tension spring 13 and the rope 216, place the upper frame 14 and lower frame 12 on the outside of the display screen, release the upper frame 14 and lower frame 12, and the tension spring 13 will cause the upper frame 14 and lower frame 12 to spring back. The display screen frame can then be inserted into the groove on the inside of the upper frame 14 and lower frame 12, thereby fixing the upper frame 14 and lower frame 12 to the display screen. The elasticity of the tension spring 13 allows the upper frame 14 and lower frame 12 to be installed on display screens of different sizes, improving the applicability of the device. When pulling the upper frame 14 and lower frame 12, the upper frame 14 and lower frame 12... 2. The upper cleaning brush 16 and the lower cleaning brush 17 can be moved synchronously by the slide rod 15. The limiting block fixed inside the upper cleaning brush 16 can cooperate with the limiting grooves on both sides of the lower cleaning brush 17 to restrict the lower cleaning brush 17 and prevent it from falling off the upper cleaning brush 16. When not installed, the lower frame 12 is placed between the baffle 10 and the stop block 11, which can restrict the lower frame 12 and prevent it from tipping over. In summary, during installation, it can be adapted to displays of different sizes, improving the applicability of the device. When installing the upper frame 14 and the lower frame 12, the lower frame 12 can use the slide rod 15 to pull the sleeve plate 18 off the slide plate 6, so that the lower cleaning brush 17 can be kept in contact with the sleeve plate 18. When maintaining the barcode scanner, the drive wheel 219 can automatically drive the bushing 7, causing the bushing 7 to rotate the reciprocating screw 5 within the slide rail 4 via the slot 8 and the locking block 9. This causes the slide plate 6 to reciprocate left and right within the slide rail 4, which in turn drives the lower cleaning brush 17 and the upper cleaning brush 16 through the sleeve plate 18 to clean the display screen and remove surface dust. The slide rod 15 can restrict the movement of the sleeve plate 18, upper cleaning brush 16, and lower cleaning brush 17, thus limiting the slide plate 6 and preventing it from tilting during movement. During use, if the tilt of the display screen is adjusted, the sleeve plate 18 and lower cleaning brush... 17 can rotate on the slide bar 15, so that the slide plate 6 and the sleeve plate 18 can always remain vertical, and the lower cleaning brush 17 and the upper cleaning brush 16 can remain parallel to the display screen. After the motor 220 stops running, the bushing 7 can drive the reciprocating screw 5 to continue to rotate several times under the action of inertia, so that the slide plate 6 drives the lower cleaning brush 17 and the upper cleaning brush 16 to approach the edge of the display screen through the sleeve plate 18, so as to prevent the lower cleaning brush 17 and the upper cleaning brush 16 from blocking the display screen. If it is not to reach the edge of the display screen, it can also be manually moved to the edge to avoid obstructing the cashier work. In summary, when not in use, it can automatically clean the display screen, and when in use, it can avoid obstructing the cashier work.

[0034] In summary, this automated maintenance equipment for cash registers requires only the following steps during installation: First, lift the upper frame 14 and lower frame 12 from the bottom frame 3. Then, pull the upper frame 14 and lower frame 12, allowing the lower frame 12 to slide on the upper frame 14. Next, pull the tension spring 13 and the rope 216. Place the upper frame 14 and lower frame 12 outside the display screen. Release the upper frame 14 and lower frame 12; the tension spring 13 will cause the upper frame 14 and lower frame 12 to spring back, allowing the display screen frame to engage with the grooves on the inner side of the upper frame 14 and lower frame 12, thus fixing the upper frame 14 and lower frame 12 onto the display screen. The elasticity of the tension spring 13 allows the upper frame 14 and lower frame 12 to be installed on displays of different sizes, improving the equipment's applicability. Furthermore, when pulling the upper frame 14 and lower frame 12, the upper frame 14 and lower frame 12 can be moved via the sliding rod 15. The upper cleaning brush 16 and the lower cleaning brush 17 slide synchronously. The limiting block fixed inside the upper cleaning brush 16 can cooperate with the limiting grooves on both sides of the lower cleaning brush 17 to restrict the lower cleaning brush 17 and prevent it from falling off the upper cleaning brush 16. When not installed, the lower frame 12 is placed between the baffle 10 and the stop block 11, which can restrict the lower frame 12 and prevent it from tipping over. When installing the upper frame 14 and the lower frame 12, the lower frame 12 can pull the sleeve 18 off the slide plate 6 through the slide rod 15, so that the lower cleaning brush 17 can be connected to the slide plate 6 through the sleeve 18. When the cash register is not in use, the barcode scanner can be inserted into the placement slot 202 and its charging end can be inserted into the placement frame 207. The connector 208 can then be inserted into the barcode scanner's charging port. Inside the electronic port, under the weight of the barcode scanner, the placement frame 207 compresses the pressure spring 206, causing the pressure rod 209 to slide downwards within the sliding cavity 204. As the pressure rod 209 moves downwards, it pulls the pull rope 216. The pull rope 216, under the action of the guide wheel 214, pulls the top rod 215 upwards within the lifting groove 210, thereby causing the cleaning wheel 213 to move within the arc groove 203 via its inclined surface. The cleaning wheel 213 can drive the transmission wheel 218 to move within the transmission cavity 217 via the shaft 212. The sliding groove 211 can restrict the cleaning wheel 213 via the shaft 212 to prevent it from tilting. When the placement frame 207 is fully lowered, part of the cleaning wheel 213 enters the placement groove 202 and interacts with the barcode scanner. When the barcode scanner head contacts the contact point 205, the pressure rod 209 contacts the contact point 205, allowing the connector 208 to charge the barcode scanner and simultaneously power the motor 220. The motor 220 then drives the transmission wheel 218 to rotate via the drive wheel 219, which in turn drives the cleaning wheel 213 to rotate within the arc groove 203 via the shaft 212, cleaning the scanning head. When the barcode scanner is removed to scan a product, the placement frame 207 rebounds under the action of the pressure spring 206, pulling the pressure rod 209 away from the contact point 205, thus disconnecting the power to the motor 220 and terminating the maintenance process. The top rod 215 also falls back under gravity, allowing the cleaning wheel 213 to slide to the lower end of the arc groove 203, preventing the cleaning wheel 213 from obstructing the removal and placement of the barcode scanner. This ensures proper barcode scanner maintenance.The drive wheel 219 can drive the bushing 7 to move synchronously and automatically, causing the bushing 7 to drive the reciprocating screw 5 to rotate within the slide rail 4 through the slot 8 and the block 9. This causes the slide plate 6 to move back and forth within the slide rail 4, thereby driving the lower cleaning brush 17 and the upper cleaning brush 16 to clean the display screen and remove dust from its surface through the sleeve plate 18. When the sleeve plate 18, the upper cleaning brush 16, and the lower cleaning brush 17 move, the slide rod 15 can restrict them, thus restricting the slide plate 6 by the sleeve plate 18 to prevent it from tilting during movement. During use, if the tilt of the display screen is adjusted... During operation, the sleeve 18 and lower cleaning brush 17 can rotate on the slide rod 15, ensuring that the slide plate 6 and sleeve 18 remain vertical, while the lower cleaning brush 17 and upper cleaning brush 16 remain parallel to the display screen. After the motor 220 stops, the bushing 7, under inertia, can drive the reciprocating screw 5 to continue rotating several times, causing the slide plate 6 to move the lower cleaning brush 17 and upper cleaning brush 16 closer to the edge of the display screen via the sleeve 18. This prevents the lower cleaning brush 17 and upper cleaning brush 16 from obstructing the display screen image. If they do not reach the edge of the display screen, they can be manually moved to the edge to avoid obstructing the cash register operation.
