Description

Technical Field

[0001] This utility model relates to the field of tobacco processing reminder equipment, specifically to a self-test reminder device that uses light reminders. Technical Background

[0002] Cigarette manufacturers have extremely strict requirements for product quality. However, due to the instability of equipment, quality problems occur at unpredictable times. In addition to conducting self-inspections of products during critical periods such as when equipment malfunctions, cigarette production operators must also conduct regular self-inspections of products during normal production to prevent defective cigarette products from entering the market.

[0003] Regular self-inspections can largely prevent quality incidents, but when operators are busy with miscellaneous tasks such as dismantling broken cigarettes, they are very likely to forget to conduct self-inspections. If a quality incident occurs at this time, it can cause great losses.

[0004] Currently, operators primarily rely on intermittently checking their watches or mobile phones to monitor the time and cultivate a habit of scheduled self-inspections. However, this method of relying on watches and phones makes it easy to forget or miss scheduled self-inspections. When quality issues arise, this can lead to the production of a large number of defective products and significant losses.

[0005] Currently, a search reveals that Chinese utility model patent CN213987189U discloses a kitchen timer device, comprising: a front shell (1), a rear shell (2), a mounting mechanism (3), a magnetic suction mechanism (4), a decorative piece (5), an electrode connecting piece (6), an angle support frame (7), a battery compartment cover (8), a DIP switch (9), and an LED light (10). While it can provide timed reminders to operators, it still suffers from the following technical drawbacks:

[0006] On the one hand, the operators are in the workshop, which is noisy, and the sound reminders are flawed, which may result in missed hearings. On the other hand, the LED lights are designed to be seen only from a specific angle.

[0007] On the other hand, it cannot count the number of self-checks performed, and only has a countdown reminder function. Summary of the Invention

[0008] To address the numerous defects and shortcomings in the aforementioned background technology, this utility model has made improvements and innovations, aiming to provide a self-test reminder device that uses light reminders. By setting two colors of light, red LED and blue LED, and by setting different light modes, such as flashing and constant light, it reminds the operator to perform self-test operations. The brightness of the light is adjustable to ensure that it can remind the operator, and it can record and count the number of self-tests for the convenience of the operator's statistics.

[0009] Another objective of this invention is to enable operators to observe changes in light from multiple angles by providing a lampshade with a semi-circular structure.

[0010] Another objective of this invention is to enable the invention to be fixed at any position on the workbench by providing a fixed magnet, which makes it easier for operators to select a location that is easy to observe before installation.

[0011] To solve the above problems and achieve the objectives of the invention, this utility model provides a self-test reminder device using light indicators, achieved through the following design structure and technical solution:

[0019] Preferably, the control circuit board (21) is a PLC control board with a chip, wherein the display screen (22), encoder (23), blue LED (24), red LED (25), timer reset button (26) and reminder reset button (27) mounted on the control circuit board (21) are electrically connected to each other;

[0020] The encoder (23) has key detection and rotation pulse direction detection functions, and the model is EC11;

[0021] The brightness of the blue LED (24) and red LED (25) is adjustable.

[0022] Preferably, the battery pack (31), power switch (32), charging interface assembly (33) and charging indicator light (34) are electrically connected;

[0023] The charging interface assembly (33) is equipped with a battery charging and discharging protection chip, which can transmit real-time charging signals to change the color of the charging indicator (34);

[0024] During the charging process of the battery pack (31), the charging interface component (33) transmits an electrical signal to the charging indicator light (34), causing the charging indicator light (34) to light up red. After the battery pack (31) is fully charged, the charging indicator light (34) lights up green.

[0025] Preferably, the battery pack (31) is connected between the control circuit board (21) and the back cover (12).

[0026] Preferably, the lampshade (13) is made of transparent material, has a semi-circular structure, a smooth outer surface, and a fine "interlaced lines or grooves or frosted" structure on the inner surface, which makes it easy for operators to observe from multiple angles.

[0027] Preferably, the display screen (22) is an OLED screen used to display real-time data.

[0028] Preferably, the observation hole is provided with a transparent shell with a rectangular recess in the middle that fits the display screen (22) and a raised perimeter that is flush with the end face of the front cover (11). The transparent shell can protect the display screen (22) while allowing observation of the display screen (22).

[0029] Preferably, the battery pack (31) is charged by connecting the charging interface assembly (33) with a mobile phone charging cable.

[0030] The working principle is as follows: Before using the above-mentioned design structure with light-based self-test reminder, the reminder must first be assembled:

[0031] During assembly, the control circuit board (21) is connected first. The display screen (22), encoder (23), blue LED (24), and red LED (25) are soldered onto the control circuit board (21), and the above components are connected to the chip via wires. The battery pack (31), power switch (32), charging interface assembly (33), and charging indicator light (34) are connected as a whole via wires, and this whole is connected to the control assembly (2) via wires. Then, the power switch (32), charging interface assembly (33), and charging indicator light (34) are passed through the holes provided on the back cover (12) so that the operation and observation of the above components can be realized on the outer wall of the back cover (12). The battery pack (31) is installed in the fixed position provided inside the back cover (12). After the bolts are passed through the holes at the four vertices of the control circuit board (21), the control circuit board (21) is fixed to the internal threaded post provided inside the back cover (12). At this time, the battery pack (31) is located between the control circuit board (21) and the back cover (12). The timer reset button (26) and reminder reset button (27) are passed through the holes in the front cover (11) and connected to the fixed positions on the control circuit board (21). The front cover (11) and the rear cover (12) are connected as a whole by snap-fit. At this time, the operating ends of the encoder (23), timer reset button (26), and reminder reset button (27) protrude from the holes in the front cover (11), and the operator operates the above components on the front cover (11). Then, the lampshade (13) is installed in the fixed holes in the front cover (11). At this time, the lampshade (13) is located directly above the red LED (25) and the blue LED (24). The fixing magnet (4) is installed at the four vertices of the end face of the rear cover (12). Thus, the assembly of this utility model is completed.

[0032] In use, the operator attaches the device to a machine near the workstation using a fixed magnet (4), presses the power switch, and the battery pack (31) powers the control circuit board (21), illuminating the display screen (22). The display screen (22) then shows the initial page displaying the time, countdown, and self-test count. The operator presses the timer reset button (26) to reset the time to zero and restart the countdown. When the time matches the countdown time, the reminder enters the reminder state, and the red LED (25) and blue LED (24) flash alternately. After receiving the reminder signal, the operator presses the reminder reset button (27), increasing the self-test count by one unit. The LED lights simultaneously turn off. The operator then performs a self-test on the products on the conveyor belt according to the operating procedure, thus ending the reminder. After completing the self-test on the finished product, the operator presses the timer reset button to reset the time to zero and restart the countdown, beginning a new self-test process.

[0033] When the self-test time period needs to be adjusted, the operator presses the encoder (23) operation terminal to display the parameter setting page on the display screen (22). At this time, the words "period", "brightness", "flickering" and "return" are displayed. The operator selects and rotates the encoder (23) to select the option. When rotating the encoder (23), the ">" icon appears in front of the option. When the encoder (23) is pressed again, the ">" changes to "·", and the item can be adjusted. When adjusting, the value is increased or decreased by rotating the encoder (23). When adjusting the "flickering" option, there are only two options, "on" and "off", which are used to adjust the red LED (25) and blue LED (21) to flash alternately or stay on at the same time. Rotating the encoder (23) is ineffective for the "return" option. The operator needs to press the encoder (23) to exit the parameter setting and return to the previous page. When the operator enters the operation page by pressing the encoder (23) but does not perform any operation for 30 seconds, it will automatically return to the initial page. When entering the parameter setting page, the timer on the initial page will not stop.

[0034] After the self-test is completed, the operator records the number of self-tests on the reminder device, records the self-test results for the day, and submits them. Finally, press the power switch (32) to turn off the device. The number of self-tests will be reset to zero after the device is turned off. Remove the device from the machine and place it in a fixed position for the next use.

[0035] When charging is required, the display screen (22) will display the word "low battery". The operator uses a mobile phone charging cable to charge this utility model. During the charging process, the charging indicator light (34) is constantly red and after charging is completed, the charging indicator light (34) is constantly green.

[0036] The control methods described above, which use encoder (23) and PLC board to achieve the above functions, are all conventional technologies in this field and do not involve improvements to computer software control. The operation process is only described here, and the specific principles and methods will not be elaborated here.

[0037] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0038] 1. This utility model, by setting red LED lights and blue LED lights with different lighting modes, such as flashing and constant light, can remind operators to perform self-inspection operations, prevent operators from forgetting self-inspection operations, and reduce the product problem rate;

[0039] 2. Because the brightness of the light is adjustable, this utility model ensures that the light can effectively remind the operator and can adjust the brightness of the reminder light to suit different work positions and preferences. It meets the needs of different work positions for adjusting the brightness of the light due to different external light conditions, and meets the light intensity that the operator can accept, preventing the light from being too bright and causing eye discomfort.

[0040] 3. By setting up a lampshade, and the inner wall of the lampshade is provided with an "interlaced line or groove or frosted" structure, the operator can install the utility model in more positions and observe the light signal even under multiple angle changes.

[0041] 4. By setting a fixed magnet, this utility model can be directly adsorbed onto a metal machine base, making the installation and disassembly process more convenient. Attached Figure Description

[0057] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] The control circuit uses a PLC and other existing control circuits, as long as they can complete the task. Figure 9 The circuit shown is controlled by logic.

[0059] Example 1

[0060] like Figures 1 to 8 The self-test reminder device shown includes: a housing assembly 1, a control assembly 2, a battery assembly 3, a fixing magnet 4, and a control circuit;

[0061] The outer casing assembly 1 includes: a front cover 11, a rear cover 12, and a lampshade 13, wherein the front cover 11 and the rear cover 12 are connected by bolts, and the lampshade 13 consists of two symmetrically installed at the fixing holes provided on the front cover 11.

[0062] The control component 2 is installed inside the housing component 1, such as Figure 5 As shown, the system includes a display screen 22, an encoder 23, a blue LED 24, a red LED 25, a timer reset button 26, and a reminder reset button 27, all mounted on the control circuit board 21. The timer reset button 26 and the reminder reset button 27 pass through holes in the front cover 11 and are connected to the control circuit board 21. The buttons are located on the outside of the front cover 11 and protrude from the end face of the front cover 11. The blue LED 24 and the red LED 25 are mounted symmetrically with the lampshade 13.

[0063] The battery assembly 3 supplies power to the control assembly 2 and includes: a battery pack 31, a power switch 32, a charging interface assembly 33, and a charging indicator light 34, wherein the power switch 32 controls the power supply and disconnection of the battery pack 31 to the control assembly 2.

[0064] The fixed magnet 4 is installed in the groove provided on the end face of the rear cover 12.

[0065] In this invention, the fixed magnet allows the reminder to be installed at any position on the machine, and facilitates installation and removal by the operator.

[0066] Furthermore, such as Figure 2 As shown, the front cover 11 has an observation hole for use with the display screen 22, an operation hole for use with the encoder 23, and a mounting hole for use with the timer reset button 26 and the reminder reset button 27 on its end face; the front cover 11 has a buckle for connection with the rear cover 12 on its inner side.

[0067] In this invention, the operator can observe the information displayed on the display screen 22 through the observation hole provided on the front cover 11.

[0068] Furthermore, the side wall of the rear cover 12 is provided with holes for use with the power switch 32, the charging interface assembly 33 and the charging indicator light 34; the interior of the rear cover 12 is provided with a limiting structure for fixing the battery pack 31 and an internal threaded post for fixing the control circuit board 21 with bolts.

[0069] In this utility model, the back cover 12 is provided with a limiting structure for fixing the battery pack 31, so that the battery pack 31 is more stably fixed after installation and the connecting wires will not be broken due to shaking.

[0070] Before use, assemble the reminder device:

[0071] During assembly, the control circuit board 21 is connected first, such as... Figure 5As shown, the display screen 22, encoder 23, blue LED 24, and red LED 25 are soldered onto the control circuit board 21, and these components are connected to the chip via wires. The battery pack 31 is connected to the power switch 32, charging interface assembly 33, and charging indicator light 34 as a whole via wires, as shown. Figure 4 As shown, the entire assembly is connected to the control component 2 via wires. Then, the power switch 32, charging interface assembly 33, and charging indicator light 34 are passed through holes in the rear cover 12, allowing operation and observation of these components from the outer wall of the rear cover 12. The battery pack 31 is installed in a fixed position inside the rear cover 12. Bolts are passed through the holes at the four vertices of the control circuit board 21 to fix the control circuit board 21 to the internally threaded posts inside the rear cover 12. At this time, the battery pack 31 is located between the control circuit board 21 and the rear cover 12. The timer reset button 26 and the reminder reset button 27 are passed through holes in the front cover 11 and connected to the fixed position on the control circuit board 21. The front cover 11 and the rear cover 12 are connected as a whole by clips. At this time, the operating ends of the encoder 23, timer reset button 26, and reminder reset button 27 protrude from the holes in the front cover 11, allowing the operator to operate these components from the front cover 11. Next, install the lampshade 13 into the fixing holes provided on the front cover 11. At this time, the lampshade 13 is directly above the red LED 25 and the blue LED 24. Install the fixing magnets 4 at the four vertices of the end face of the rear cover 12. This completes the assembly of this utility model.

[0072] In use, the operator attaches this utility model to a machine near the operating station using the fixing magnet 4, such as... Figure 1 As shown, pressing the power switch supplies power to the control circuit board 21 via battery pack 31, illuminating the display screen 22. The initial page on display screen 22 shows the time, countdown, and self-test count. The operator presses the timer reset button 26 to reset the time to zero and restart the countdown. When the time matches the countdown time, the reminder enters reminder mode, with red LED 25 and blue LED 24 flashing alternately. Upon receiving the reminder signal, the operator presses the reminder reset button 27, incrementing the self-test count by one unit, and the LEDs simultaneously turn off. The operator then performs self-tests on the products on the conveyor belt according to the operating procedure, thus ending this reminder. After completing the self-test of the finished products, the operator presses the timer reset button to reset the time to zero and restart the countdown, beginning a new self-test process.

[0073] When the self-test time cycle needs to be adjusted, the operator presses the encoder 23 operating terminal to display the parameter setting page on the display screen 22, such as... Figure 6As shown, the text "Period", "Brightness", "Flash" and "Return" are displayed at this time. The operator selects the option via the rotary encoder 23. When the rotary encoder 23 is rotated, the ">" icon appears before the option, as shown. Figure 7 As shown, pressing encoder 23 again changes ">" to "·", as shown. Figure 8 As shown, this item can be adjusted by rotating encoder 23 to increase or decrease the value. The "Blinking" option only has "On" and "Off" settings, used to adjust whether the red LED 25 and blue LED 21 flash alternately or remain constantly lit. Rotating encoder 23 has no effect on the "Return" option; pressing encoder 23 is required to exit parameter settings and return to the previous page. If the operator enters the operation page by pressing encoder 23 but does not perform any operation for 30 seconds, it will automatically return to the initial page. When entering the parameter settings page, the timer on the initial page will not stop.

[0074] After the self-test is completed, the operator records the self-test count on the reminder device, records the self-test results for the day, and submits them. Finally, press the power switch 32 to turn off the device. The self-test count will be reset to zero after power-off. Remove the device from the machine and place it in a fixed location for future use.

[0075] When charging is required, the display screen 22 will display the message "Low battery". The operator uses a mobile phone charging cable to charge the device. During the charging process, the charging indicator light 34 will be constantly red, and after charging is completed, the charging indicator light 34 will be constantly green.

[0076] The control methods described above, which use encoder 23 and PLC board to achieve the above functions, are all conventional technologies in the field and do not involve improvements to computer software control. This embodiment and the following embodiments only describe the operation process, and the specific principles and methods will not be repeated.

[0077] Example 2

[0078] Furthermore, the control circuit board 21 is a PLC control board with a chip, wherein the display screen 22, encoder 23, blue LED light 24, red LED light 25, timer reset button 26 and reminder reset button 27 mounted on the control circuit board 21 are electrically connected to each other.

[0079] The encoder 23 has key detection and rotation pulse direction detection functions, and the model is EC11.

[0080] The brightness of the blue LED 24 and the red LED 25 is adjustable.

[0081] In this invention, when it is necessary to adjust the self-test time and lighting effects, the operator presses the encoder 23 operating terminal to display the parameter setting page on the display screen 22, such as... Figure 6 As shown, the text "Period", "Brightness", "Flash" and "Return" are displayed at this time. The operator selects the option via the rotary encoder 23. When the rotary encoder 23 is rotated, the ">" icon appears before the option, as shown. Figure 7 As shown, pressing encoder 23 again changes ">" to "·", as shown. Figure 8 As shown, this item can be adjusted by rotating encoder 23 to increase or decrease the value. The "Blinking" option has only two settings: "On" and "Off," used to adjust whether the red LED 25 and blue LED 21 flash alternately or remain constantly lit. Rotating encoder 23 has no effect on the "Return" option; pressing encoder 23 exits the parameter setting and returns to the previous page. If the operator enters the operation page by pressing encoder 23 but does not perform any operation for 30 seconds, it will automatically return to the initial page. When entering the parameter setting page, the timer on the initial page will not stop.

[0082] Furthermore, the battery pack 31, power switch 32, charging interface assembly 33, and charging indicator light 34 are electrically connected;

[0083] The charging interface assembly 33 is equipped with a battery charging and discharging protection chip, which can transmit real-time charging signals to change the color of the charging indicator 34.

[0084] During the charging process of the battery pack 31, the charging interface component 33 transmits an electrical signal to the charging indicator light 34, causing the charging indicator light 34 to light up red. When fully charged, the charging indicator light 34 lights up green.

[0085] In this invention, the design of the charging interface component 33 allows the operator to determine whether the battery pack 31 is fully charged by observing the color of the charging indicator light 34 during the charging process.

[0086] Furthermore, the battery pack 31 is connected between the control circuit board 21 and the rear cover 12.

[0087] Furthermore, the lampshade 13 is made of transparent material, has a semi-circular structure, a smooth outer surface, and a fine "interlaced lines or grooves or frosted" structure on the inner surface, which facilitates observation by the operator from multiple angles.

[0088] In this utility model, the lampshade 13 is made of transparent material, and the inner surface is provided with a fine "interlaced lines or grooves or frosted" structure, so that the light is absorbed by the fine "interlaced lines or grooves or frosted" structure on the lampshade 13 during the transmission process, so that the operator can observe the light signal from multiple angles and realize the operator's self-inspection reminder.

[0089] Furthermore, the display screen 22 is an OLED screen used to display real-time data.

[0090] In this invention, the display screen 22 uses an OLED screen, which provides higher brightness and makes it easier for operators to observe the time.

[0091] Furthermore, the observation hole is provided with a transparent shell with a rectangular recess in the middle that fits the display screen 22 and protrusions around the edges that are flush with the end face of the front cover 11. This transparent shell can protect the display screen 22 while allowing observation of the display screen 22.

[0092] Furthermore, the battery pack 31 is charged by connecting the charging interface assembly 33 via a mobile phone charging cable.

[0093] In this invention, a mobile phone charging cable is used to charge the battery pack 31, which makes it more compatible and convenient for operators.

[0094] Example 3

[0095] This embodiment 3 is the same as embodiment 1 and embodiment 2, except that the top side wall of the rear cover 12 is also provided with a foldable hook. The operator can use the hook to hang the utility model at a height that is easy to observe, such as at the same level as the line of sight, so as to better prompt the operator to perform self-inspection.

[0096] In summary, a more specific embodiment of this utility model is as follows:

[0097] like Figure 4 As shown, a self-test reminder device using light reminders includes a housing assembly 1, a control assembly 2, a battery assembly 3, and a fixing magnet 4.

[0098] Before use, the operator must assemble the reminder device, starting with connecting the control circuit board 21. This involves soldering the display screen 22, encoder 23, blue LED 24, and red LED 25 onto the control circuit board 21. Figure 5 As shown, the components are connected to the chip via wires. The battery pack 31, power switch 32, charging interface assembly 33, and charging indicator light 34 are connected as a whole via wires, and this whole assembly is connected to the control component 2 via wires. Then, the power switch 32, charging interface assembly 33, and charging indicator light 34 are passed through holes provided on the rear cover 12, as shown. Figure 4As shown, the operation and observation of the aforementioned components can be achieved on the outer wall of the rear cover 12. The battery pack 31 is installed in a fixed position inside the rear cover 12. Bolts are passed through the holes at the four vertices of the control circuit board 21 to fix the control circuit board 21 to the internally threaded posts inside the rear cover 12. At this time, the battery pack 31 is located between the control circuit board 21 and the rear cover 12. The timer reset button 26 and the reminder reset button 27 are passed through the holes in the front cover 11 and connected to the fixed position on the control circuit board 21. The front cover 11 and the rear cover 12 are connected as a whole by snap-fit ​​mechanisms. At this time, the operating ends of the encoder 23, the timer reset button 26, and the reminder reset button 27 protrude from the holes in the front cover 11, allowing the operator to operate the aforementioned components on the front cover 11. Next, the lampshade 13 is installed in the fixed hole in the front cover 11, with the lampshade 13 positioned directly above the red LED 25 and the blue LED 24, respectively. The fixing magnet 4 is installed at the four vertices of the end face of the rear cover 12. This completes the assembly of this utility model.

[0099] In use, the operator attaches this utility model to the machine platform near the operating station using the fixing magnet 4, such as... Figure 1 As shown, pressing the power switch supplies power to the control circuit board 21 via battery pack 31, illuminating the display screen 22. The display screen 22 then shows the initial page displaying information such as time, countdown, and self-test count. The PLC board control here uses conventional technology; this description only covers the operation process. The operator presses the timer reset button 26 to reset the timer to zero and restart it. When the countdown reaches the set time, the system enters a reminder state. The red LED 25 and blue LED 24 flash alternately or remain constantly lit. Upon receiving the light reminder signal, the operator presses the reminder reset button 27, incrementing the self-test count by one unit. The red LED 25 and blue LED 24 turn off. The operator then performs a self-test on the products on the conveyor belt according to the operating procedure, thus ending the reminder. After completing the self-test on the finished products, the operator presses the timer reset button to reset the timer to zero and restart it, beginning a new self-test process.

[0100] When the self-test time cycle needs to be adjusted, the operator presses the encoder 23 operating terminal to display the parameter setting page on the display screen 22, such as... Figure 6 As shown, the text "Period", "Brightness", "Flash" and "Return" are displayed at this time. The operator selects the option via the rotary encoder 23. When the rotary encoder 23 is rotated, the ">" icon appears before the option, as shown. Figure 7 As shown, pressing encoder 23 again changes ">" to "·", as shown. Figure 8As shown, this item can be adjusted by rotating encoder 23 to increase or decrease its value. The "Blinking" option has only two settings: "On" and "Off," used to adjust whether the red LED 25 and blue LED 21 flash alternately or remain constantly lit. Rotating encoder 23 has no effect on the "Return" option; pressing encoder 23 at the "Return" option exits the parameter setting and returns to the previous page. If the operator enters the operation page by pressing encoder 23 but does not perform any operation for 30 seconds, it will automatically return to the initial page. When entering the parameter setting page, the timer on the initial page will not stop.

[0101] After the self-test is completed, the operator records the self-test count on the reminder device, records the self-test results for the day, and submits them. Finally, press the power switch 32 to turn off the device. The self-test count will be reset to zero after power-off. Remove the device from the machine and place it in a fixed location for future use.

[0102] When charging is required, the display screen 22 will display the message "Low battery". The operator uses a mobile phone charging cable to charge the device. During the charging process, the charging indicator light 34 will be constantly red, and after charging is completed, the charging indicator light 34 will be constantly green.

[0103] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.

[0104] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
