Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing teaching desks and chairs, and particularly to an automated manufacturing device for integrated teaching desks and chairs with multifunctional interfaces. Background Art

[0002] In recent years, with the rapid development of information technology and the needs of educational modernization, the infrastructure in the teaching environment has been continuously upgraded. To meet the usage requirements of multimedia devices, computers, and other electronic devices in modern teaching, teaching desks and chairs equipped with sockets and multifunctional interfaces have emerged. Such desks and chairs not only provide the basic functions of traditional desks and chairs but also integrate various electrical interfaces such as power sockets, USB interfaces, and network ports, greatly improving the convenience and efficiency in the teaching process.

[0003] Currently, during the production process of most teaching desks and chairs with sockets and multifunctional interfaces, the assembly of the leg sheaths still relies on manual operation. This method not only consumes a large amount of human resources, resulting in increased production costs, but also has low efficiency and is difficult to meet the needs of large-scale production. Secondly, the sockets and multifunctional interfaces on teaching desks and chairs are often in an open state during transportation, storage, and processing. In this case, external dust and impurities can easily enter the interface, causing short circuits or other electrical failures. Moreover, the interface parts are also extremely vulnerable to collision and mechanical damage during handling or installation, not only reducing the service life but also potentially causing safety hazards. Summary of the Invention

[0004] In view of this, the present invention provides an automated manufacturing device for integrated teaching desks and chairs with multifunctional interfaces, which can overcome the disadvantages that manual assembly of leg sheaths not only consumes a large amount of human resources, resulting in increased production costs, but also has low efficiency, and external dust and impurities can easily enter the interfaces of teaching desks and chairs, causing short circuits or other electrical failures, and the interface parts are also extremely vulnerable to collision and mechanical damage during handling or installation, not only reducing the service life but also potentially causing safety hazards.

[0005] The technical solution is as follows: An integrated teaching desk and chair automatic manufacturing device with multifunctional interfaces, including a bottom plate, a guide plate, a sliding rod, a lifting platform, a first spring, a loading guide rail, a mounting plate, a guide frame, a feeding guide rail, a feeding mechanism, a pushing mechanism and a protection mechanism. Two guide plates are connected to the top of the bottom plate. Two sliding rods are slidably connected inside each guide plate. A lifting platform is connected to the four sliding rods. A first spring is connected between the guide plate and the lifting platform. Loading guide rails are connected to the left and right sides of the top of the lifting platform. Two mounting plates are connected to the top of the bottom plate. Guide frames are connected to the top of the mounting plates. The loading guide rails are located inside the guide frames and are slidably matched with the guide frames. Feeding guide rails are connected to the guide frames. The feeding guide rails communicate with the guide frames and correspond to the loading guide rails. The table leg sheaths will move along the feeding guide rails into the loading guide rails.

Openings are formed in the upper right part of the front-side support plate and the lower rear part of the feed bin respectively, and the openings on the front-side support plate and the feed bin correspond to each other. The protective shell can be moved out of the feed bin through this opening. Two second guide frames are connected to the front-side support plate. A second slide plate is slidably connected to the two second guide frames together. A fourth spring is connected between the second guide frame and the second slide plate. A mounting rod is connected to the second slide plate. A second electric suction cup is installed on the mounting rod. The second electric suction cup passes through the front side of the feed bin. A pull plate is connected to the first push plate. The pull plate is used to pull the second slide plate backward. The second slide plate drives the second electric suction cup to move backward. The second electric suction cup sucks the protective cover and pushes the protective shell backward. The protective shell is adhered to the teaching desks and chairs through the adhesive stickers to protect the interface part of the teaching desks and chairs.

[0010] Furthermore, it also includes a first electric push rod and a first baffle. The first electric push rods are installed on the support plates respectively.

[0033] Refer to Figures 1 - 14, An integrated teaching desk and chair automatic manufacturing device with multi-functional interfaces, including a bottom plate 1, guide plates 2, sliding rods 3, a lifting platform 4, a first spring 5, a loading guide rail 6, mounting plates 7, guide frames 8, a feeding guide rail 9, a feeding mechanism, a pushing mechanism, and a protection mechanism. On the right side of the top of the bottom plate 1, two guide plates 2 are connected by bolts. The two guide plates 2 are symmetrically arranged left and right. Two sliding rods 3 are slidably connected inside each of the guide plates 2. The upper ends of the four sliding rods 3 are jointly connected to the lifting platform 4. The four sliding rods 3 jointly guide the lifting platform 4, which can improve the stability of the lifting platform 4. A first spring 5 is sleeved on each of the sliding rods 3. The two ends of the first spring 5 are respectively connected to the guide plate 2 and the lifting platform 4. The first spring 5 is sleeved on the sliding rod 3, which can prevent the first spring 5 from bending. On the left and right sides of the top of the lifting platform 4, loading guide rails 6 are connected. On the right side of the top of the bottom plate 1, two mounting plates 7 are connected by bolts. The two mounting plates 7 are symmetrically arranged left and right. Guide frames 8 are connected to the tops of the mounting plates 7. The loading guide rail 6 is located inside the guide frame 8, and the loading guide rail 6 and the guide frame 8 are in sliding fit. The guide frame 8 can guide the loading guide rail 6 to make the movement of the loading guide rail 6 more stable. Moreover, the guide frame 8 can block the table leg sheaths inside the loading guide rail 6 to prevent the table leg sheaths inside the loading guide rail 6 from falling. At the lower part of the front side of each guide frame 8, a feeding guide rail 9 is connected. The feeding guide rail 9 is communicated with the guide frame 8 and corresponds to the loading guide rail 6. Two notches (not marked, can be seen in Figure 2 are opened on one side of the two loading guide rails 6 close to each other. The table leg sheaths can be moved out of the loading guide rail 6 through this notch. The feeding mechanism is used to convey the teaching desk and chair to directly above the lifting platform 4. The pushing mechanism is used to push the table leg sheaths onto the table legs of the teaching desk and chair. The protection mechanism is used to protect the interface part of the teaching desk and chair.

[0034] Referring to Figure 4 , the feeding mechanism includes support plates 101 and a conveyor 102. Support plates 101 are connected by bolts to the front and rear sides of the top of the bottom plate 1. The conveyors of 102 are installed on the tops of the support plates 101 by bolts.

[0035] Referring to Figures 5 - 9, the pushing mechanism includes a first guide frame 111, a first slide plate 112, a second spring 113, a first electric suction cup 114, a sliding frame 115, an electric guide rail 116, a first push plate 117, a second push plate 118 and a blocking component. On the sides of the two loading guide rails 6 away from each other, a first guide frame 111 is connected. A first slide plate 112 is slidably connected to each first guide frame 111. A second spring 113 is sleeved on the front and rear parts of the first guide frame 111. The two ends of the second spring 113 are respectively connected to the first guide frame 111 and the first slide plate 112. The second spring 113 is sleeved on the first guide frame 111, which can prevent the second spring 113 from bending. Two first electric suction cups 114 are installed on both the front and rear sides of the first slide plate 112. The first electric suction cup 114 penetrates through the loading guide rail 6. On the left and right sides of the bottom of the lifting table 4, a sliding frame 115 is slidably connected. The top of the sliding frame 115 is connected to the bottom of the first slide plate 112. On the right side of the top of the bottom plate 1, an electric guide rail 116 is installed by bolts. The electric guide rail 116 is located between the two guide plates 2. The top of the slider of the electric guide rail 116 is connected to the first push plate 117 by bolts. The front side of the top of the first push plate 117 is an inclined surface (not marked, can be seen in Figure 8 ), on the left and right sides of the front part of the first push plate 117, a second push plate 118 is connected by bolts. The rear parts of the second push plates 118 are all inclined (not marked, can be seen in Figure 8 ), and the blocking component is used to block the table leg sheaths in the loading guide rail 6.

[0036] Referring to Figure 9 , the blocking component includes a guide rod 119, a wedge-shaped stopper 1110 and a third spring 1111. On the upper and lower sides of the loading guide rail 6, a pair of guide rods 119 are symmetrically connected in the front and rear. A wedge-shaped stopper 1110 adapted to the notch on the loading guide rail 6 is slidably connected to each pair of guide rods 119. The wedge-shaped stopper 1110 is located in the notch on the loading guide rail 6. When the table leg sheath moves into the loading guide rail 6, the table leg sheath will contact the inclined surface (not shown in the figure) of the wedge-shaped stopper 1110. A third spring 1111 is sleeved on each guide rod 119. The two ends of the third spring 1111 are respectively connected to the guide rod 119 and the wedge-shaped stopper 1110. The third spring 1111 is sleeved on the guide rod 119, which can prevent the third spring 1111 from bending.

[0037] Referring to Figures 10 - 14, the protection mechanism includes a charging bin 121, a Teflon conveyor belt 122, a protective shell 123, a protective cover 124, an adhesive patch 125, a magnet 126, a second guiding frame 127, a second sliding plate 128, a fourth spring 129, a mounting rod 1210, a second electric suction cup 1211 and a pulling plate 1212. The charging bin 121 is bolted to the upper right front side of the front support plate 101. The Teflon conveyor belt 122 is bolted to the inner rear side of the charging bin 121. The protective cover 124 is hinged to the front side of the protective shell 123. The adhesive patch 125 is connected to the rear side of the protective shell 123. The magnet 126 is connected to the front side of the protective shell 123. The rear side of the protective cover 124 contacts the front side of the magnet 126. The position where the protective cover 124 contacts the magnet 126 is made of iron, so that the magnet 126 can suck the protective cover 124 to prevent the protective cover 124 from being opened randomly. Teflon is a material made of polytetrafluoroethylene and has excellent non-stick properties, so the adhesive patch 125 will not stick to the Teflon conveyor belt 122. Openings (not shown in the figure) are provided in the upper right front side of the front support plate 101 and the lower rear side of the charging bin 121. The opening on the front support plate 101 corresponds to the opening on the charging bin 121. The protective shell 123 can be removed from the charging bin 121 through this opening. Two second guiding frames 127 are bolted to the upper right front side of the front support plate 101. The two second guiding frames 127 are symmetrically arranged up and down. The second sliding plate 128 is slidably connected to the two second guiding frames 127 together. The two second guiding frames 127 guide the second sliding plate 128 together, which can improve the stability of the second sliding plate 128. Two fourth springs 129 are sleeved on the second guiding frames 127. The two ends of the fourth spring 129 are respectively connected to the second guiding frame 127 and the second sliding plate 128. The fourth spring 129 is sleeved on the second guiding frame 127, which can prevent the fourth spring 129 from bending. Two mounting rods 1210 are connected to the upper rear side of the second sliding plate 128. The second electric suction cups 1211 are mounted at the rear ends of the mounting rods 1210. The second electric suction cups 1211 pass through the lower front side of the charging bin 121. The pulling plate 1212 is bolted to the front side of the first pushing plate 117.

[0038] The staff place the teaching desks and chairs on two conveyors 102. The conveyors 102 convey the teaching desks and chairs to the right, transport the teaching desks and chairs directly above the lifting platform 4, and then place the protective shell 123 into the material box 121. The Teflon conveyor belt 122 can convey the protective shell 123 downward, transport the protective shell 123 directly behind the electric suction cup two 1211. Then, the front end of the feeding guide rail 9 is docked with the discharging end of the disc loader. The disc loader feeds the table leg sheaths into the feeding guide rail 9. The table leg sheaths move along the feeding guide rail 9 into the loading guide rail 6. The table leg sheaths will move to the notch of the loading guide rail 6. The wedge-shaped stopper 1110 can block the table leg sheaths to prevent the table leg sheaths from falling from the notch of the loading guide rail 6. At this time, the table leg sheaths will contact the inclined surface of the wedge-shaped stopper 1110. Control the electric guide rail 116 to drive the first push plate 117 and the second push plate 118 to move backward. The first push plate 117 pushes the lifting platform 4 upward through the inclined surface, and the first spring 5 stretches. The lifting platform 4 drives the loading guide rail 6 upward, so that the table leg sheaths in the loading guide rail 6 correspond to the table legs of the teaching desks and chairs. At this time, the loading guide rail 6 and the feeding guide rail 9 are staggered. Subsequently, the inclined part of the second push plate 118 will contact the sliding frame 115 and push the two sliding frames 115 to move towards each other. The sliding frame 115 drives the two first sliding plates 112 to move towards each other, and the second spring 113 stretches. The first sliding plates 112 drive the electric suction cups one 114 on the left and right to move towards each other. The electric suction cups one 114 suck the table leg sheaths and assemble the table leg sheaths onto the table legs of the teaching desks and chairs. Automatically assembling the table leg sheaths can save manpower and improve production efficiency. Since the table leg sheaths contact the inclined surface of the wedge-shaped stopper 1110, when the electric suction cups one 114 push the table leg sheaths, the table leg sheaths can push the wedge-shaped stopper 1110, enabling the table leg sheaths to cross over the wedge-shaped stopper 1110, and the third spring 1111 compresses. The backward movement of the first push plate 117 can also drive the pull plate 1212 to move backward. During the backward movement of the pull plate 1212, it will contact the second sliding plate 128 and pull the second sliding plate 128 to move backward, and the fourth spring 129 compresses. The second sliding plate 128 drives the mounting rod 1210 to move backward, and the mounting rod 1210 drives the electric suction cup two 1211 to move backward. The electric suction cup two 1211 sucks the protective cover 124 and pushes the protective shell 123 backward. The protective shell 123 is adhered to the teaching desks and chairs through the adhesive sticker 125 to protect the interface part of the teaching desks and chairs, prevent dust and impurities from entering the interior of the interfaces of the teaching desks and chairs, thus avoiding short circuits or other electrical faults, and being able to prevent the interface parts of the teaching desks and chairs from being collided and mechanically damaged. Then, control the electric guide rail 116 to drive the first push plate 117 and the second push plate 118 to move forward. The second push plate 118 is separated from the sliding frame 115. Under the action of the second spring 113, the two first sliding plates 112 move away from each other. The first sliding plates 112 drive the electric suction cups one 114 on the left and right to move away from each other.The first push plate 117 no longer pushes the lifting table 4. Under the action of the first spring 5, the lifting table 4 and the loading guide rail 6 will move downward. The loading guide rail 6 corresponds to the feeding guide rail 9 again. The first spring 5 can provide a downward pulling force for the loading guide rail 6 to ensure that the loading guide rail 6 can accurately correspond to the feeding guide rail 9. The forward movement of the first push plate 117 can also drive the pull plate 1212 to move forward. The pull plate 1212 is separated from the second slide plate 128. Under the action of the fourth spring 129, the second slide plate 128 will move forward, and the second slide plate 128 drives the mounting rod 1210 and the second electric suction cup 1211 to move forward and reset.

[0039] Refer to Figure 15 It also includes a first electric push rod 131 and a first baffle 132. The upper right parts of the support plates 101 are all installed with the first electric push rod 131 through bolts. The telescopic rods of the first electric push rod 131 are all connected with the first baffle 132, and the first baffle 132 slidably penetrates through the support plate 101.

[0040] When the conveyor 102 conveys the teaching desks and chairs to the right, the first baffle 132 can block the teaching desks and chairs to ensure that the teaching desks and chairs can accurately stop directly above the lifting table 4, and ensure that the table leg sheaths can be accurately assembled onto the table legs of the teaching desks and chairs. After the table leg sheaths are assembled, control the telescopic rod of the first electric push rod 131 to extend, driving the two first baffles 132 to move away from each other, so that the first baffle 132 no longer blocks the teaching desks and chairs.

[0041] Refer to Figure 15 It also includes a second electric push rod 141 and a second baffle 142. The middle upper parts of the support plates 101 are all installed with the second electric push rod 141 through bolts. The telescopic rods of the second electric push rod 141 are all connected with the second baffle 142, and the second baffle 142 slidably penetrates through the support plate 101.

[0042] When the conveyor 102 conveys the teaching desks and chairs to the right, control the telescopic rod of the second electric push rod 141 to extend, driving the two second baffles 142 to move away from each other, so that the second baffle 142 does not block the teaching desks and chairs. When the teaching desks and chairs move to directly above the lifting table 4, control the telescopic rod of the second electric push rod 141 to shorten, driving the two second baffles 142 to move closer to each other, and the second baffle 142 blocks the next teaching desk and chair to avoid the two teaching desks and chairs from contacting each other, so as to avoid the first guide frame 111 colliding with the next teaching desk and chair when moving upward.

[0043] Refer to Figure 1 It also includes a limiting plate 15. The top of the support plates 101 are all connected with the limiting plate 15 through bolts. When the conveyor 102 conveys the teaching desks and chairs to the right, the limiting plate 15 can limit the teaching desks and chairs to prevent the teaching desks and chairs from shaking.
