Description

Technical Field

[0001] The present invention relates to the field of industrial production line teaching and training, and particularly to an employee training interactive display device. Background Art

[0002] In recent years, with the advancement of China's modernization drive, more and more manufacturing factories have been transforming towards automation and intelligence. In these modern factories, due to the improvement of the overall automation level and intelligence level, the processes that require manual participation have gradually decreased. Generally, only personnel (emergency operators) need to be set at key nodes of the production line for supervision to handle emergencies, so as to ensure the safety of equipment, materials, and personnel on the entire production line under emergency conditions. However, in the actual production process, we found that due to the large number of overall equipment on the modern intelligent production line, high prices, and high degree of connection, if the production line is stopped or shut down due to training needs, it will cause huge economic costs. This has led to the fact that emergency operators often do not have very sufficient practical operation and handling opportunities. Moreover, based on the dual considerations of safety risks, it is even more difficult to directly let new employees operate on the line. At the same time, enterprises are also difficult to bear the direct economic damage caused by operation errors during the training process, which further leads to the scarcity of practical operation opportunities for emergency operators on such modern industrial production lines. In addition, due to the characteristics of high connection and high value of the equipment in such factories, it is also very difficult to use additional purchased model machines, old units, etc. as training teaching carriers. Therefore, the training of employees is often still carried out through traditional methods such as text, picture display + oral explanation. However, this traditional teaching mode often leads to employees lacking intuitive and clear understanding, and has a very limited effect on improving employees' operation level and handling ability.

[0024] Combined with Figures 1-6As shown, the present invention discloses an employee training interactive display device, especially for employee training in various industrial production lines, and can also be derivatively applied to various flight training and driving training industries. It realizes a closed and all-round simulation of the actual operation environment, helping enterprises improve the efficiency and effect of employee training. From the overall structure, the present invention mainly includes two major components, including a training chamber 1, and an actuating platform 2 arranged at the bottom of the training chamber 1 for carrying terminal models. The training chamber 1 realizes an all-round visual simulation of the environment through circumferential visual presentation, and the actuating platform 2 is used to carry terminal models, such as: models of areas near emergency stop buttons, models of areas near control panels, etc., to achieve a high-fidelity and low-cost simulation of the actual production line.

[0025] Before use, training preparation needs to be carried out first. According to the training category, terminal models need to be prepared. The terminal models are generally models of the operation areas of the equipment to be trained, that is, models of a small part of the equipment, such as: models of areas near emergency stop buttons, models of areas near the control panels of production equipment, etc. According to actual training needs, they are generally made and prepared by users themselves and can be connected to the interface of this device through various data transmission lines. The terminal models are installed on the actuating platform 2 for use. For other main structures of the equipment to be trained, generally, due to cost considerations, they are not included in the terminal models, but are visually simulated through display devices. After the terminal models are fixed on the actuating platform, the training preparation is completed. The actuating platform 2 can be used to simulate some common emergency working conditions that may occur at the site, such as vibration and tilt, to achieve somatosensory interaction with the trainer.

[0026] As the most special core structure of the present invention, the training chamber 1, as Figure 1 shown in the figure, generally adopts a structure of upper and lower double circles + middle side supports. Its circumferential enclosure is composed of an OLED flexible display panel 7, that is, the training chamber 1 includes a circular bottom ring 3, a top ring 4, and support columns 5. One side of the bottom ring 3 and the top ring 4 is connected by the support columns 5. The OLED flexible display panel 7 can be hidden and stored inside the support columns 5, or can move and unfold along the top ring 4 and the bottom ring 3.

[0027] This layout structure is mainly designed to adapt to the changing training needs. Since there are many types of terminal models, and most of them are steel components on industrial production lines, which are partial models of production line equipment. On the one hand, they are heavy and large in volume. If a fully fixed cylindrical enclosure is adopted (for example, directly setting the side of the training warehouse 1 as a cylindrical support and installing display devices on the inner wall surface of the support), although the terminal model can enter and exit through the opening of the warehouse door, due to the heavy weight of the terminal model itself, even with a warehouse door, it is not convenient for hoisting and forklifting, and is not conducive to model replacement. On the other hand, traditional display devices such as LCD and LED are vulnerable parts, and are also prone to being bumped and impacted during the installation process of the terminal model, which is not conducive to their use. However, through the flexible characteristics of OLED in the present invention, it is subjected to curling and storage processing. On the one hand, the installation space can be fully exposed in the storage state, and it can cooperate with various forklifts, lifting tools, etc. to realize the flexible installation of the terminal model. On the other hand, it is convenient to form a fully circumferential closed enclosure.

[0028] Specifically, as shown in combination with Figure 1 and 5 In the present invention, a winding shaft 6 is arranged inside the support column 5, and an OLED flexible display panel 7 with the display surface facing inwards is wound on the winding shaft 6. The winding shaft 6 is controlled to rotate by a motor, and the winding and unwinding are formed by rotation. As shown in Figure 5 In the figure, the winding shaft 6 is driven by a reel motor 37. The reel motor 37 can adopt a high-precision servo motor and can be used in cooperation with various speed measurement sensors to achieve precise control of winding and unwinding. At the same time, in order to facilitate the teaching staff to understand the status of the trainees, as well as to realize the simulation of the sound environment and the interactive control with this device, the present invention can also be provided with a camera 38, a speaker 39, a microphone, etc., and a control board 40 for human-computer interaction with this device. These components are generally directly installed on the support column 5.

[0029] As shown in Figure 1 In the figure, the bottom ring 3 and the top ring 4 are both provided with tracks extending circumferentially, and a dragging mechanism connected to one end of the OLED flexible display panel 7. The dragging mechanism can cooperate with the unwinding of the winding shaft 6 to drag the OLED flexible display panel 7 to advance one week along the track, forming a closed, cylindrical chamber. The dragging mechanism can also cooperate with the winding of the winding shaft 6 to retreat one week along the track, so that the OLED flexible display panel 7 is all retracted into the support column 5 to completely open the space between the bottom ring 3 and the top ring 4.

[0030] The personnel to be trained enter the training warehouse 1. The dragging mechanism of the training warehouse 1 drags the OLED flexible display panel 7 to make a full circle, constructing a closed chamber space. The OLED flexible display panel 7 facing inward simulates a complete workshop visual environment inside. At this time, the OLED flexible display panel 7 plays various pre-prepared video files or videos simulated and generated by software on an external PC, so as to conduct a full-range closed visual simulation of the actual working environment. At the same time, the actuating platform 2 can cooperate to realize motion simulations such as vibration and inclination, realizing interactive training for employees in a real environment. When it is necessary to replace different terminal models, the OLED flexible display panel 7 can be completely retracted into the support column 5, opening up the entire space, which is very convenient for operations such as hoisting and installing the terminal model, laying a good executable foundation for multi-type teaching and multi-scenario teaching. At the same time, it can avoid damage to the OLED flexible display panel 7 such as knocking and impact during the installation and debugging of the terminal model, ensuring the overall service life and safety of the device.

[0031] To further ensure the stability of the overall operation of the dragging mechanism of the present invention, both the bottom ring 3 and the top ring 4 of the present invention include a ring body 8 with an annular cavity provided inside. As Figure 2 shown, taking the top ring 4 as an example, the cavity of the ring body 8 constitutes the track. The cavity sequentially includes a guard edge section 9 and a supporting section 10 in the direction away from the middle of the training warehouse 1. The groove surfaces on both sides of the supporting section 10 are provided with a first inclined surface 11, and a running groove 12 is arranged along the circumferential direction of the ring body 8 on the first inclined surface 11 for running components such as running gears and running rubber wheels to run.

[0032] Combined with Figure 2 and 3 shown, the dragging mechanism includes running frames 13 respectively arranged in the supporting sections 10 of the top ring 4 and the bottom ring 3, and a dragging plate 14 arranged between the two running frames 13. The running frames 13 are used to actively run in the cavity of the ring body 8. The end of the OLED flexible display panel 7 is connected to the dragging plate 14, and the running frames 13 drive the OLED flexible display panel 7 to move through the dragging plate 14. As Figure 3 shown, the two side surfaces of the running frame 13 are provided with a second inclined surface 15, and the inclination is adapted to the first inclined surface 11. Two groups of running wheels 16 are arranged at the position of the running groove 12 corresponding to the second inclined surface 15 of the running frame 13, and the running wheels 16 are driven by a running motor 17 located inside the running frame 13.

[0033] With the walking mechanism described in the present invention, the walking frame 13 on the top ring 4 forms an inclined plane support for the second inclined plane 15 through the first inclined plane 11, and the support stability is better. At the same time, the double inclined planes cooperate with the walking groove 12 to form a double walking guide for the limit of the walking wheel 16, so that the overall running stability of the device is better. The double inclined plane support of the walking guide structure on the bottom ring 3 can also adopt a similar (upper and lower symmetric) structure. In this case, since the first inclined plane 11 does not directly participate in the longitudinal support of the second inclined plane 15, the walking frame 13 located on the lower side has a certain downward fall, which can generate a certain longitudinal pulling force on the OLED flexible display panel 7 to ensure the regularity of the plane of the OLED flexible display panel 7. However, the full suspension of the lower walking frame 13 should also be avoided, for example, by setting a support block on its body or setting a support block at the bottom of the groove cavity of the bottom ring 3 to form a certain support.

[0034] Regarding the specific driving form of the walking wheel 16 of the present invention, one better solution can be as Figure 3 shown in the figure, the walking motor 17 is connected to the wheel axle of the walking wheel 16 through a walking driving component. The walking driving component includes a driving rod 18 horizontally arranged in the walking frame 13. Both ends of the driving rod 18 are respectively connected to the wheel axle of the walking wheel 16 through a cross coupling. A driven wheel 19 is arranged in the middle section of the driving rod 18. The output end of the walking motor 17 is provided with a driving wheel 20, and the driving wheel 20 is connected to the driven wheel 19 through a transmission belt 21. When walking, the driving rod 18 drives the driving wheel 20, the transmission belt 21, the driven wheel 19, and the driving rod 18 to act in sequence, and finally transmits the power to the walking wheel 16 through the cross coupling. This driving structure is compact and reasonable, and can achieve a better match with the walking frame 13. To ensure the rotational stability of the driving rod 18, a shaft sleeve 22 is sleeved outside the driving rod 18 near both ends, and the shaft sleeve 22 is fixedly arranged on the walking frame 13 through a short rod.

[0035] Since the walking frame 13 of the present invention is a moving part and the overall circular motion distance is relatively long, in order to avoid complex power wiring and improve the overall simplicity, as Figure 2 shown in the figure, a conductive sheet 23 extending along the circumferential direction of the ring body 8 is arranged in the groove cavity of the ring body 8 of the present invention. The conductive sheet 23 is connected to an external power supply and can be directly installed on the inner surface of the whole body 8 under the condition of meeting the insulation requirements. A contact elastic sheet 24 electrically connected to the walking motor 17 is arranged at a position on the walking frame 13 opposite to the conductive sheet 23, and is in contact with the conductive sheet 23 through the contact elastic sheet 24 to form power supply for the walking motor 17.

[0036] Although the flexible OLED display panel 7 used in the present invention is flexible and can move effectively along the track on the ring body 8 under the dragging of the dragging mechanism, since it is generally a vulnerable display device, its edge protection should be well done. In appropriate cases, an additional outer protective cloth can be provided for external protection. The winding and dragging structures of the protective cloth are similar to those of the flexible OLED display panel 7. A certain gap is maintained between the protective cloth and the flexible OLED display panel 7 to leave sufficient buffer space, and some simple external impacts are buffered and offset by the protective cloth.

[0037] In terms of edge protection, in the present invention, a number of clamping rollers 25 are arranged along the circumferential direction of the ring body 8 on the side walls of the ring body 8 on both sides of the groove cavity edge protection section 9. A clamping area capable of clamping the edge of the flexible OLED display panel 7 is formed between the clamping rollers 25. On the one hand, the clamping rollers 25 can play a role in reducing friction and facilitate the movement of the flexible OLED display panel 7. On the other hand, they can also play a certain role in internal support. At the same time, the clamping rollers 25 located outside the clamping area can approach or move away from the inner clamping rollers 25 under the drive of the clamping drive assembly. After the flexible OLED display panel 7 moves into place, the outer clamping rollers 25 can be used to achieve positioning clamping. The cylindrical surface of the clamping rollers 25 should avoid using pure rigid materials, but can use some materials with appropriate hardness and buffering strength, such as rubber, plastic, etc.

[0038] Regarding the driving form of the outer clamping rollers 25, the present invention can adopt the following scheme, such as Figure 2 As shown in, the clamping drive assembly includes a pressure chamber 26 provided on the circumferential wall of the ring body 8 outside the clamping area. The pressure chamber 26 extends along the circumferential direction of the ring body 8. The two ends of the outer clamping roller 25 are installed at one end of the core rod 27 and form a rotational fit with the core rod 27. A sleeve 28 communicating with the pressure chamber 26 is provided inside the pressure chamber 26. The other end of the core rod 27 passes through the sleeve 28 and extends into the pressure chamber 26, and a end plate 29 is provided at the end. The clamping drive assembly further includes an air inlet 30 and a pressure relief port 31 communicating with the pressure chamber 26. Electric control valves are provided at the air inlet 30 and the pressure relief port 31 and are controlled by the control panel 40 for easy operation by the user. When clamping and locking are required, high-pressure air is introduced into the pressure chamber 26. The internal pressure of the pressure chamber 26 rises, pushing the core rod 27 to extend along the sleeve 28, thereby driving the outer clamping roller 25 to move inward and clamping and fixing the flexible OLED display panel 7 between the inner and outer clamping rollers 25.

[0039] As the dragging plate 14 used in the present invention for directly connecting with the flexible OLED display panel 7, its specific structure can be as Figure 4As shown in the figure, the drag board 14 includes two end plates 32 for connecting to two walking frames 13, and a top bar 33 with a triangular cross-section disposed between the pointed sides of the end plates 32. A connecting bar 34 for fixing the OLED flexible display panel 7 is disposed at the rear side of the top bar 33. During the movement, the pointed side of the top bar 33 faces forward, and it can relatively easily push open the clamping edge roller 25, so that the outer clamping edge roller 25 is pushed outward in the non-pressurized state of the pressure chamber 26, realizing the clearance of the movement channel of the OLED flexible display panel 7.

[0040] The support column 5 of the present invention is an important component for connecting the top ring 4 and the bottom ring 3. It needs to integrally support the weight of the ring body 18 and its upper components. In order to improve its structural strength, it can adopt a hollow square column or be composed of double column rods 35. In the case of the double-layer column rods 35, as Figure 5 shown in the figure, the support column 5 includes two vertical column rods 35 arranged side by side and socket parts 36 disposed at both ends of the column rods 35. The support column 5 is sleeved outside the top ring 4 and the bottom ring 3 through the socket parts 36 and is bolted to the top ring 4 and the bottom ring 3. A winding shaft 6 is disposed between the two column rods 35. On this basis, in order to further improve the weighing performance of the whole device, ribs 41 extending vertically are disposed at the two edges of the inner column rod 35. A reinforcing plate 42 extending radially along the top ring 4 is further disposed at the top of the support column 5. A cross-shaped reinforcing rod 43 is fixedly disposed inside the top ring 4. A plurality of diagonal braces 44 are uniformly arranged in a ring shape at the top of the top ring 4. The lower end of the diagonal brace 44 is fixedly connected to the top ring 4, and the upper end is fixedly connected to the top plate 45. A vertical rod 46 is further disposed at the cross center of the reinforcing rod 43. The vertical rod 46 passes through the reinforcing plate 42 and is fixedly connected to the top ring 4. In terms of the top enclosure, a ceiling curtain can be directly laid on the diagonal braces 44.

[0041] The actuating platform 2 of the present invention adopts three-cylinder actuation. Through the telescopic cooperation of the three cylinders, various common working conditions such as vibration and inclination can be effectively simulated. As Figure 6 shown in the figure, an annular mounting edge 47 is disposed on the inner edge of the ring body 8 of the bottom ring 3. The actuating platform 2 includes a platform body 48 and three hydraulic actuating cylinders 49 disposed at the bottom of the platform body 48. One end of the hydraulic actuating cylinder 49 is hinged to the mounting edge 47, and the other end is hinged to the platform body 48. In order to achieve the closure of the gap, an elastic sealing ring 50 is disposed between the edge of the platform body 48 and the ring body 8 of the bottom ring 3.
