Detailed Implementation

[0016] This embodiment discloses a novel automated mobile phone case packaging device, mainly used to complete the step of inverting and packaging mobile phone cases into plastic trays during the production and packaging process. It is suitable for operation on factory assembly lines. Since material transport equipment in factories is generally conveyor belts and factory space is difficult to modify, this invention uses a conveyor belt as a transport platform to meet the requirements for operation within a factory.

[0017] Details are as attached Figure 1-6 As shown, the device includes a conveyor belt 1, a plastic tray supply mechanism disposed on the conveyor belt 1, and a joining mechanism for joining the phone case and the plastic tray together. The joining mechanism includes an integrated frame 7, a stepper motor A6, a phone case baffle 14 and a plastic tray front baffle 11 for limiting the movement of the phone case and the plastic tray, a ramp 13 disposed between the phone case baffle 14 and the plastic tray front baffle 11, and a push rod 15 disposed on one side of the phone case.

[0018] The integrated frame 7 is mounted on the side beam 2 of the conveyor belt 1 via a hinge support 10. A stepper motor A6 is fixed to the side beam 2, and its output shaft is connected to the integrated frame 7, allowing the frame 7 to deflect. A phone case baffle 14 is fixed to the integrated frame 7, a ramp 13 is fixed to the end of the integrated frame 7, and a plastic tray front baffle 11 is fixed to the ramp 13. When the integrated frame 7 deflects, it causes the phone case baffle 14, the ramp 13, and the plastic tray front baffle 11 to deflect together. When it deflects to the position on the conveyor belt 1, it can stop the phone case and plastic tray on the conveyor belt 1. The phone case baffle 14 corresponds to the front end of the phone case on the conveyor belt 1, and the plastic tray front baffle 11 corresponds to the front end of the plastic tray on the conveyor belt 1. Preferably, the phone case baffle 14 and the plastic tray front baffle 11 are staggered and not flush, with the plastic tray front baffle 11 positioned slightly forward. This ensures that after stopping the phone case and plastic tray, their positions correspond perfectly, allowing the push rod 15 to smoothly push the phone case into the plastic tray. Furthermore, a plastic tray rear baffle 12 is correspondingly provided behind the plastic tray front baffle 11, with the front and rear baffles 11 and 12 arranged in pairs. The plastic tray is confined between these two baffles. In this embodiment, three sets of plastic tray front baffles 11 and 12 are provided, and three corresponding sets of phone case baffles 14 are also provided, all connected to the ramp 13 to form a single unit, enabling the simultaneous stopping of three phone cases and three plastic trays.

[0019] The number of push rods 15 is the same as the number of phone cases to be stopped. In this embodiment, a three-pronged push rod is used. One end of the push rod contacts the phone case and pushes it into the plastic tray. The other end is hinged to the crank 17. The stepper motor B drives the crank 17 to deflect. In order to prevent the push rod 15 from lateral vibration or deflection during operation, a guide device is designed. The guide device includes a slide rod 21 mounted on the side beam 2 via a base 19. One end of the slide rod 21 is fixed to the base 19, and the other end extends into the middle of the conveyor belt 1. A support beam 22 is also provided. One end of the support beam 22 is fixed to the base 19, and the other end is fixed to the end of the slide rod 21. A connecting rod 16 is connected to the slide rod 21 via a sliding sleeve 20. The other end of the connecting rod 16 is hinged to the push rod 15. The sliding sleeve 20 and the slide rod 21 form a sliding pair. When the push rod 15 is working, it drives the sliding sleeve 20 to move on the slide rod 21 to provide the push rod 15 with degrees of freedom.

[0020] Crank 17 is connected to crank hinge support 18, and stepper motor B is fixed to side beam 2 by bolts. Preferably, guide devices can be provided at both ends of push rod 15, depending on the number of push rods 15. When push rod 15 is not working, it rests on slide bar 21 to avoid direct contact with the running conveyor belt 1, and the end of push rod 15 is a cylindrical push head to prevent it from getting stuck during operation.

[0021] The plastic tray supply mechanism includes a storage box 9 for holding plastic trays, a friction wheel shaft 24 located below the storage box 9, and friction wheels 25 mounted on the friction wheel shaft 24. Friction wheel shafts 24 are located on both the left and right sides below the storage box 9. Two friction wheels 25 are mounted on each friction wheel shaft 24, and pulleys 27 are also mounted on the friction wheel shaft 24 to drive its rotation. A column 8 is mounted on the side beam 2 via angle bolts 14. The storage box 9 is fixedly connected to the column 8 via a bracket 30, and two pulley motors 35 are mounted on the bracket 30, which are respectively connected to the pulleys 27 on the two friction wheel shafts 24 via synchronous toothed belts. Preferably, a connecting block 26 is fixedly provided on the side of the storage box 9, and the friction wheel shaft 24 is mounted on the connecting block 26 via bearings 23. One end of the bracket 30 has a connecting sleeve corresponding to the column 8, which is fitted onto the outside of the column 8 and fixed by quick-release bolts 29.

[0022] The storage box 9 is open at both the top and bottom; the top is for loading, and the bottom is for unloading. The friction wheel 25 slightly intrudes into the storage box 9. After a plastic tray is placed in the storage box 9, it falls down and is stopped by the friction wheel 25 just before falling out from below. When a plastic tray needs to be supplied, the friction wheel 25 starts to rotate. Due to friction and compression, the bottommost plastic tray is pulled out by the friction wheel and falls onto the conveyor belt, at which point the friction wheel stops rotating. The subsequent plastic trays continue to slide downwards until they are stopped by the friction wheel again, and this cycle repeats. The size and friction coefficient of the friction wheel can be perfectly replicated through simulation and adjustment.

[0023] Because the position of the phone case on conveyor belt 1 changes after passing through the joining mechanism, the combined plastic support and phone case need to be reset to facilitate subsequent work. Therefore, a position adjustment mechanism is set behind the joining structure, including a left guide baffle 4 and a right guide baffle 5. The combined plastic support and phone case move between the left and right guide baffles to return to their original position. A left guide baffle base 3 and a right guide baffle base 34 are respectively provided on the left and right sides of the side beam 2. The left guide baffle 4 is connected to the left guide baffle base 3 via a guide rod, and the right guide baffle 5 is connected to the right guide baffle base 34 via a guide rod 33. The connection is secured with quick-release bolts, enabling position adjustment.

[0024] In this embodiment, stepper motor A, stepper motor B, and pulley motor 35 are all powered by 12V.

[0025] In use, the infrared sensor installed on the conveyor belt 1 transmits the detected position of the phone case to the control system. The control system, based on features such as whether the phone case has reached a designated position, drives the pulley motor 35 to drive the friction wheel 25. Driven by friction, the plastic tray falls onto one side of the phone case on the conveyor belt 1. Then, when the plastic tray and phone case reach the appropriate position, the infrared sensor is triggered, and the control system drives the stepper motor A6 to lower the integrated frame 7 to stop the phone case and plastic tray. At this time, the action of the phone case baffle 14 and the plastic tray front baffle 11... The phone case and the plastic tray are positioned in a suitable relative position. At this time, the plastic tray is located between the front baffle 11 and the rear baffle 12 of the plastic tray, and the phone case is in contact with the phone case baffle 14. After the integrated frame 7 is fully lowered, the control system continues to drive the stepper motor B connected to the crank 17, which drives the crank 17 to rotate and then drives the push rod 15 to slide down the slide bar 21 to push the phone case on the conveyor belt 1 onto the slide ramp 13 and continue to push the phone case so that it can accurately slide into the plastic tray under the guidance of the front baffle 11 and the rear baffle 12 of the plastic tray to complete the connection.

[0026] After the phone case and plastic tray are combined, the control system controls the integrated frame 7 to lift up. The conveyor belt 1 continues to drive the combination of the plastic tray and the phone case forward to the position adjustment mechanism. The plastic tray carrying the phone case first contacts the left guide baffle 4. The left guide baffle 4 applies force to the plastic tray, causing it to change its angle and move towards the middle of the conveyor belt. Then the right guide baffle 5 restores its angle and precisely adjusts the plastic tray to the middle of the conveyor belt for subsequent production steps.

[0027] This utility model, based on the shapes of the plastic tray and the phone case, designs key components such as a plastic tray supply mechanism, a plastic tray-phone case bonding mechanism, and a position adjustment mechanism. The plastic tray supply mechanism places a plastic tray on one side of each phone case. This step facilitates subsequent bonding of the phone case and the plastic tray, ensuring they are in a relatively close and suitable position. The phone case-plastic tray bonding mechanism uses a phone case baffle 14, a front plastic tray baffle 11, and a rear plastic tray baffle 12 to adjust the relative position of the phone case and the plastic tray to a suitable state for mechanism operation and guides the phone case to accurately fall into the plastic tray. A push rod 15 pushes the phone case up a ramp 13, which then slides onto the plastic tray to complete the packaging. After packaging, due to lateral displacement of the phone case, the position adjustment mechanism adjusts the bonded plastic tray and phone case back to the conveyor center to facilitate subsequent production processes.

[0028] Based on the requirements of the infrared sensors and control system, a preset electrical control strategy is implemented (electrical control technology for production lines is widely available in existing technologies and will not be elaborated upon here). The production line can monitor the position of materials on the conveyor belt in real time and drive each mechanism to move accurately. This step is to achieve the automation function of the production process, that is, to determine the start time of each mechanism's movement based on the absolute and relative positions of the phone case and plastic tray on the conveyor belt. The infrared sensors are the eyes of the production line, constantly observing the position of materials on the conveyor belt and transmitting this information to the control system. The control system is the brain, processing and analyzing the position data, and outputting corresponding control signals according to preset algorithms and strategies to drive the coordinated movement of components such as stepper motors, pulley motors, cranks, push rods, and integrated frames.

[0029] Finally, based on design requirements and standards, simulations and tests are conducted on the production line to verify its performance and effectiveness, optimize its structure and parameters, and improve its reliability and stability. This step is to verify whether the production line design is reasonable and effective, and to make necessary improvements and refinements. Simulation involves modeling the production line's operation on a computer and observing its motion state, mechanical response, energy consumption analysis, and other indicators.

[0030] In addition to being easy to maintain and having low manufacturing and operating costs, the structure of this utility model also has the following beneficial effects: 1. Improve the efficiency of combining phone cases and plastic trays. Three phone cases can be combined with plastic trays in one work cycle, significantly improving production efficiency.

[0031] 2. Reduce labor costs. Automated production lines can reduce the need for and input of manual labor, save human resources, and reduce the cost and risk of industrial production.

[0032] 3. Improved safety. Automated production lines can avoid human dangers and injuries, ensuring the safety of the production process.

[0033] 4. Adapting to the needs of modern industrial production. Automated production lines can accommodate different types and models of industrial control equipment, such as PLCs and industrial embedded mainframes, meeting the demands of automation, efficiency, and intelligence in modern industrial production. This improves the efficiency and yield of packaging mobile phone cases into plastic trays, while reducing labor and machinery operating costs.

[0034] 5. Reduced pollutant emissions. Automated production lines use only a small number of electronic components such as electric motors and infrared sensors, resulting in low emissions and low noise during operation, thus meeting the sustainability requirements of the production process.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
