Description

Technical Field

[0002] The TV shell refers to the outer shell of the TV. It is the external structural component of the TV. It mainly protects the internal electronic components, provides mechanical support and beautifies the appearance. The shell is usually made of plastic, metal or composite materials. The appearance requirements are very high, and there must be no scratches, wear or stains on the surface. The suspended transmission mechanism can make the shell suspended during the packaging process to avoid contact with the transmission equipment and ensure the appearance quality of the product. Moreover, the shells of these electronic products have various shapes, including thin and light, curved and other different shapes. The suspended transmission can flexibly adapt to the transmission requirements of various shapes.

[0003] During the transportation of the TV shell, a soft cushion is added to the belt conveyor system to reduce the hard contact between the product and the conveying device. The TV shell transported by the cushion can be transferred. During the transfer process, the TV shell can be more smoothly transferred to other transportation equipment, making the entire transportation process smoother.

[0004] In the prior art, the suspended transmission mechanism of some shell packaging machines transports the TV shell through a conveyor belt during use, and uses the conveyor belt in combination with a buffer pad material. Due to the limitation of the buffer pad material itself, there is still the problem of aging and failure after long-term operation, and the method of adding a soft buffer pad cannot completely eliminate the potential risks brought by physical contact, resulting in scratches on the TV shell and affecting the quality of the TV shell.

[0016] The present invention provides a suspended transmission mechanism for a shell packaging machine, which has the following beneficial effects: 1. Through the high-pressure air pump, high-pressure air is blown upward through the air outlet pipe, and then the high-pressure gas is sprayed through multiple micro nozzles to form an air cushion layer. As the air cushion effect appears, the TV case on the right end protection mechanism is blown up by the high-pressure gas, and the TV case gradually separates from the supporting surface and begins to float, thereby reducing the surface scratches and deformation problems of the TV case caused by direct contact during the transmission process, and improving the quality stability of the finished product.

[0017] 2. Start the high-pressure air pump and blow high-pressure air upward through the air outlet pipe. The gas enters the support frame and spreads between the square plate and the partition plate. The increased air pressure pushes the sealing ring, which drives the sliding column and the positioning plate to move upward, compresses the spring 1 to store potential energy, and the reaction force of the spring 1 makes the positioning plate and the sliding column tend to reset, which indirectly acts on the sealing ring. After the sealing ring moves upward, a gap is generated between the sealing ring and the partition plate. The gas passes through the gap between the sliding column and the partition plate and diffuses upward evenly. Finally, multiple micro nozzles stably and evenly spray high-pressure gas, thereby improving the uniformity and stability of the high-pressure gas spray.

[0018] 3. By pushing the sleeve to slide, the two guide plates outside the sleeve are restricted by the threads of the threaded opening, and begin to rotate and slide downward, generating friction with the positioning tube in the process to achieve buffering. The rotation and sliding of the sleeve drives the limit plate to press down spring 2, which stores elastic potential energy. Then spring 2 releases the potential energy and applies a reverse force to the downward impact of the TV case, thereby buffering the impact and reducing deformation, dents or damage to the case due to collision.

[0019] 4. Two connecting plates are used to drive a sector gear to rotate respectively. Because the two are meshed with each other to form a restriction, the two rotating plates are forced to rotate around the pin and push the transmission column to slide. The two transmission columns slide towards each other, driving the two sliding plates to move to the similar side, and then the arc plates are driven to slide through the two fixed plates. Finally, the two arc plates protect the TV case to prevent the TV case from falling due to insufficient high-pressure gas, thereby ensuring its stability and safety during the transmission process.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to the attached Figure 1-3The embodiment of the present invention provides a suspended transmission mechanism of a shell packaging machine, including a bottom plate 1, the bottom plate 1 provides a transport support for a TV shell, the right end of the bottom plate 1 is fixedly connected with a driving mechanism 2, the driving mechanism 2 is used to realize the driving source of the TV shell transportation, the driving mechanism 2 includes a protective box 202 and two guide blocks 205, the bottom end of the protective box 202 is fixedly connected to the right end of the bottom plate 1, and is connected by a welding process so that the protective box 202 is firmly connected, the inside of the protective box 202 is fixedly connected with a motor 201, the protective box 202 is fixed to the motor 201 by a welding process, so that the motor 201 can operate stably, the driving end of the motor 201 is fixedly connected with a threaded rod 203, and the threaded rod 203 is used as a transmission component to transmit the rotation force of the driving end of the motor 201, the external thread of the threaded rod 203 is connected with a threaded sleeve 204, the threaded sleeve 2 04 can realize linear motion when the threaded rod 203 rotates. The guide block 205 is internally slidably connected to the guide rail 206. The guide rail 206 is limited to enable the guide block 205 to stably slide in a straight line. The bottom sides of the two guide rails 206 are respectively fixedly connected to the front and rear ends of the top side of the bottom plate 1, and are connected by welding technology to ensure that the guide rails 206 will not be displaced during use. The threaded rod 203 is fixedly connected to the side away from the motor 201 with a positioning column 207. The positioning column 207 is driven to rotate synchronously by the threaded rod 203. The external rotation of the positioning column 207 is connected to a positioning plate 208. The positioning column 207 is limited by the positioning plate 208, so that the threaded rod 203 can rotate stably to avoid deviation. The bottom side of the positioning plate 208 is fixedly connected to the left end of the top side of the bottom plate 1, and is connected by welding technology to ensure the stable support of the positioning plate 208. Specifically, the motor 201 in the protective box 202 is started, and the threaded rod 203 is driven to rotate by the motor 201. Since the threaded sleeve 204 is threadedly connected to the threaded rod 203, when the threaded rod 203 rotates, the threaded sleeve 204 will move linearly along the threaded rod 203. At the same time, under the restriction of the guide rail 206, the guide block 205 will also slide linearly with the threaded sleeve 204, thereby realizing the movement of the entire driving mechanism 2. In this way, the driving mechanism 2 can drive the TV housing placed on the bottom plate 1 for transportation, provide transmission power for the subsequent packaging process, ensure that the TV housing can move efficiently and smoothly on the suspended transmission mechanism, and complete the transportation process from the feed to the packaging station.

[0024] Please refer to the attached Figure 2-4, the top side of the driving mechanism 2 is fixedly connected with a suspension mechanism 3, and the suspension mechanism 3 is used to suspend the TV shell. The suspension mechanism 3 includes a support plate 301 and a sliding column 308. The bottom side of the support plate 301 is fixedly connected to the top side of the threaded sleeve 204, and the support plate 301 is driven to slide synchronously by the movement of the threaded sleeve 204. The front and rear ends of the bottom side of the support plate 301 are respectively fixedly connected to the top sides of the two guide blocks 205. The support plate 301 is restricted by the guide blocks 205 so that the support plate 301 can slide stably in a straight line. The top side of the support plate 301 is fixedly connected with a support frame 302, and the support frame 302 provides a storage space for high-pressure gas. The top side of the support frame 302 is fixedly connected with a limited position frame 303, and the limited position frame 303 is used to guide the high-pressure gas. A plurality of micro nozzles 304 are fixedly connected to the top of the support frame 302. The micro nozzles 304 are made of stainless steel, have the characteristics of high temperature resistance and corrosion resistance, and have a long service life. The bottom end of the support frame 302 is fixedly connected with a square plate 305; The inner top of the support frame 302 is fixedly connected to a partition plate 306, and the square plate 305 is perpendicular to the partition plate 306, so as to provide storage space for high-pressure gas. The bottom end of the suspension mechanism 3 is fixedly connected to a high-pressure air pump 3012, and the high-pressure air pump 3012 can provide a stable, high-pressure gas source. The driving end of the high-pressure air pump 3012 is fixedly connected to an outlet pipe 307, and the outlet pipe 307 transports the high-pressure gas to between the square plate 305 and the partition plate 306. The outer sleeve of the sliding column 308 is provided with a spring 309, and the spring 309 is restricted so that the spring 309 can be uniformly stressed. One end of the plurality of springs 309 is fixedly connected to the bottom side of the partition plate 306, and the springs are welded by a welding process. The spring 1 309 is used for restriction to ensure that the position of the spring 1 309 is stable. The bottom side of the sliding column 308 is fixedly connected with a positioning plate 3010, and the positioning plate 3010 is driven to slide by the sliding column 308. The other end of the spring 1 309 is fixedly connected to the top side of the positioning plate 3010. The positioning plate 3010 is forced to slide and squeeze the spring 1 309, so that the spring 1 309 can store elastic potential energy, and then give the positioning plate 3010 a reverse force to reset. The top side of the sliding column 308 is fixedly connected with a sealing ring 3011, and the sealing ring 3011 can prevent gas leakage, so that the high-pressure gas is stored between the square plate 305 and the partition plate 306, and finally the sealing ring 3011 is pushed upward together; Specifically, the high-pressure gas pump 3012 is started, and its driving end drives the air outlet pipe 307 to deliver the high-pressure gas to the space between the square plate 305 and the partition plate 306 in the support frame 302. As the gas is continuously injected, the pressure gradually increases, and the gas pushes the sealing ring 3011 upward, and the sealing ring 3011 drives the sliding column 308 to move upward, and then drives the positioning plate 3010 to slide upward and squeeze the spring 1 309, so that the spring 1 309 is compressed and stores elastic potential energy. When the gas pressure reaches a certain level, the high-pressure gas is ejected at high speed from multiple micro nozzles 304 to form an upward airflow. The TV housing placed above the suspension mechanism 3 is gradually lifted up under the action of this upward airflow to achieve suspended operation. At the same time, due to the presence of the spring 1 309, when the gas pressure fluctuates or there is external interference to make the suspension state unstable, the spring 1 309 will release the elastic potential energy, push the positioning plate 3010 and the sealing ring 3011 to reset, thereby adjusting the gas ejection state and maintaining the stable suspension support for the TV housing. During the whole process, the support plate 301 will slide synchronously with the movement of the threaded sleeve 204, thereby driving the entire suspension mechanism 3 to move, thereby transporting the television housing in the suspended state and delivering it to the subsequent packaging process location.

[0025] Please refer to the attached Figure 1 , Figure 6 and Figure 8 , the left and right ends of the top side of the bottom plate 1 are fixedly connected with protective mechanisms 5, and the protective mechanisms 5 are used to buffer the TV casing. The two protective mechanisms 5 include two vertical plates 501, and the bottom sides of multiple vertical plates 501 are respectively fixedly connected to the four corners of the top side of the bottom plate 1, and are connected by welding technology to ensure the stability of the vertical plates 501. The adjacent sides of the multiple vertical plates 501 are fixedly connected with strip plates 502, and the adjacent sides of the two strip plates 502 are fixedly connected with multiple positioning shafts 503, which are used for the flow of high-pressure gas to lift the TV casing, and the middle parts of the adjacent sides of the multiple vertical plates 501 are fixedly connected with fixed blocks 504, which are connected by welding. The connection process is used to fix the vertical plate 501 and the fixed block 504, so as to improve the connection strength. The internal sliding connection of the strip plate 502 is connected with a sliding rod 505. The restriction of the strip plate 502 enables the sliding rod 505 to slide up and down stably. The bottom side of the sliding rod 505 is fixedly connected with a circular plate 506. The circular plate 506 can limit the downward movement of the sliding rod 505. The bottom end of the sliding rod 505 is rotatably connected with a positioning cylinder 507. The restriction of the positioning cylinder 507 enables the sliding rod 505 to rotate stably. The top side of the fixed block 504 is fixedly connected to the bottom side of the positioning cylinder 507 to ensure the stable position of the positioning cylinder 507. Please refer to the attached Figure 1 , Figure 7 and Fig. 9The outer rotation of the circular plate 506 is connected to the inner top of the positioning cylinder 507. The circular plate 506 can rotate and slide stably through the restriction of the positioning cylinder 507. The inner rotation of the positioning cylinder 507 is connected to the sleeve plate 5013. The sleeve plate 5013 can rotate stably through the restriction of the positioning cylinder 507. The inner rotation of the sleeve plate 5013 is connected to the limiting disk 508, so that the limiting disk 508 can be suspended. The left and right sides of the sleeve plate 5013 are fixedly connected with guide disks 509, which can provide guidance for the movement of the sleeve plate 5013. The outer wall of the positioning cylinder 507 is provided with two threaded openings 5010, which provide guidance for the guide disk 509. The outer part of the guide plate 509 is slidably connected to the inside of the threaded opening 5010, so that the guide plate 509 can be frictionally rotated in the form of a thread. The bottom side of the limit plate 508 is fixedly connected with a spring 2 5011. The limit plate 508 slides and squeezes the spring 2 5011, so that the spring 2 5011 can store elastic potential energy, and then give the limit plate 508 a reverse force to reset. The bottom end of the spring 2 5011 is fixedly connected to the bottom side of the inner wall of the positioning cylinder 507, and is connected by a welding process to ensure that the action of the spring 2 5011 is stable. The top sides of the two sliding rods 505 are fixedly connected with a force plate 5012, and the force plate 5012 is used to receive the TV shell; Specifically, when the TV housing is placed on the force plate 5012, its weight will cause the force plate 5012 to be pressed down, driving the sliding rod 505 to slide downward along the strip plate 502. At this time, the circular plate 506 also moves downward, and rotates and slides in the positioning cylinder 507, and the sleeve plate 5013 rotates and moves accordingly due to the rotation of the positioning cylinder 507 and the limiting plate 508, and the guide plate 509 slides and rotates in the threaded opening 5010, playing a role of guiding and limiting. In this process, the spring 2 5011 is compressed by the limiting plate 508, storing elastic potential energy, thereby providing an upward reaction force for the force plate 5012, playing a role of buffering the impact force of the TV housing being placed. At the same time, the positioning shaft 503 on the vertical plate 501 and the strip plate 502 assists in supporting the TV case and does not hinder the flow of high-pressure gas around it, so as to cooperate with the suspension mechanism 3 to suspend the TV case, ensure that the TV case is effectively protected and buffered during transportation, avoid damage caused by collision or impact, and ensure that the TV case can stably carry out subsequent transportation and packaging processes on the transmission mechanism.

[0026] Please refer to the attached Figure 1 and 5The top sides of the two protection mechanisms 5 are fixedly connected to the limiting mechanism 4, which can further limit the transmission shell. The limiting mechanism 4 includes a top plate 405, and the left and right ends of the bottom side of the top plate 405 are respectively fixedly connected to the top sides of the two vertical plates 501. The vertical plates 501 and the top plate 405 are fixed by welding technology, so that the top plate 405 can provide stable support. The left and right ends of the bottom side of the top plate 405 are both provided with strip openings 401, and the front and rear ends of the top plate 405 are slidably connected with the sliding plate 4 02, the sliding plate 402 can slide stably through the restriction of the top plate 405, the left and right ends of the bottom side of the sliding plate 402 are fixedly connected with fixed plates 403, and the fixed plates 403 can slide synchronously through the sliding plate 402, and the adjacent sides of the multiple fixed plates 403 are fixedly connected with two arc plates 404, and the arc plates 404 can limit the shell in an embracing manner, and the adjacent sides of the two sliding plates 402 are fixedly connected with connecting plates 406, and the sliding plates 402 are driven to slide synchronously through the connecting plates 406; The connecting plate 406 is internally slidably connected with a transmission column 407, and the connecting plate 406 is driven to slide forward and backward by the transmission column 407. The outer wall of the transmission column 407 is fixedly connected with a rotating plate 408, and the rotating plate 408 is driven to rotate synchronously after the rotating plate 408 is subjected to force. The middle part of the rotating plate 408 is rotatably connected with an opening plate 409, and the rotating plate 408 is driven to rotate by the transmission column 407. The end of the rotating plate 408 away from the connecting plate 406 is fixedly connected with a concave plate 4010, and the rotating plate 408 is driven to rotate synchronously by the concave plate 4010. The adjacent sides of the two concave plates 4010 are fixedly connected with a connecting plate 4011, and the adjacent sides of the two connecting plates 4011 are fixedly connected with a sector gear 401 2. The rotational force is transmitted to the fan gear 4012 through the connecting plate 4011. The inner rotation of the concave plate 4010 is connected with a pin. The outer sides of the two pins are respectively fixedly connected to the inner right end of the top plate 405. By fixing the pins, the top plate 405 can rotate stably and limit the concave plate 4010. The adjacent ends of the two fan gears 4012 are meshed. The fan gears 4012 can achieve specific movement and force transmission through meshing. The front side of one of the opening plates 409 is fixedly connected with a cylinder 4013, which is used to provide power. The driving end of the cylinder 4013 is fixedly connected to the rear side of the other opening plate 409, so that the two rotating plates 408 can slide relative to each other. Specifically, by starting the cylinder 4013, the driving end of the cylinder 4013 pushes or pulls one of the opening plates 409, and the opening plate 409 drives the rotating plate 408 connected thereto to rotate around the pin. Since the two concave plates 4010 are connected by the connecting plate 4011, and the two fan-shaped gears 4012 are meshed, when one rotating plate 408 rotates, the meshing transmission of the fan-shaped gears 4012 drives the other rotating plate 408 to rotate in the opposite direction. The rotation of the rotating plate 408 drives the transmission column 407 to slide in the connecting plate 406, and the connecting plate 406 moves forward and backward with the movement of the transmission column 407, thereby driving the sliding plate 402 to slide on the top plate 405. The fixed plate 403 at the bottom of the sliding plate 402 and the arc plate 404 connected to the fixed plate 403 will move closer or farther with the movement of the sliding plate 402, thereby realizing the surrounding limiting of the TV housing. When it is necessary to adjust the tightness of the limit or release the TV casing, the cylinder 4013 is driven in reverse to make the components move in the opposite direction, and the arc plate 404 releases the limit on the TV casing so that the TV casing can be subsequently transported or processed, ensuring that the TV casing can be stably limited during the entire transmission process to avoid accidents such as deviation or falling of the TV casing due to insufficient high-pressure gas.

[0027] Working principle: First, place the TV case on the right-hand force plate 5012, the right-hand force plate 5012 is for loading, and the left-hand force plate 5012 is for unloading. When the TV case is placed on the right-hand force plate 5012, the right-hand force plate 5012 is stressed, and the two fixed sliding rods 505 slide, and then the circular plate 506 slides, and then the cover plate 5013 slides. After that, the two guide plates 509 outside the cover plate 5013 are restricted by the threads of the threaded opening 5010, so that The sleeve plate 5013 can rotate and slide downward. In the process of the sleeve plate 5013 rotating and sliding downward, the two guide plates 509 and the positioning cylinder 507 are driven to generate friction, so that they can be buffered. As the sleeve plate 5013 rotates and slides downward, the limit plate 508 is driven to slide downward and squeeze the second spring 5011, so that the second spring 5011 can store elastic potential energy, and then give the TV housing a force in the opposite direction of the downward impact, thereby further buffering and reducing the deformation, dents or damage of the housing caused by collision. Then, the threaded rod 203 is driven to rotate by the driving motor 201, and then the threaded sleeve 204 is driven to slide to the right, thereby driving the support plate 301 to slide to the right, and then driving the support frame 302 to slide to the right, until the support frame 302 slides to the bottom of the right end protection mechanism 5, and then the high-pressure air pump 3012 is driven to blow high-pressure air upward through the air outlet pipe 307, and then the gas will slowly spread between the square plate 305 and the partition plate 306, and then the low pressure will resist all the sealing rings 3011, so that the sealing ring 3011 can drive the sliding column 308 to slide upward, and then drive the positioning plate 3010 to slide upward and squeeze the spring 1 309, so that the spring 1 309 can store elastic potential energy, and then give the sealing ring 3011 a reverse force through the positioning plate 3010 and the sliding column 308 to reset it. The sliding of the sliding column 308 makes the sealing ring 3011 no longer fit with the partition plate 306. At this time, the gas passes through the gap between the sliding column 308 and the partition plate 306, so that the gas can spread upward evenly through the partition plate 306, and then the high-pressure gas is ejected through the multiple micro nozzles 304, and then an air cushion layer is formed. As the air cushion effect appears, the TV casing on the right end protection mechanism 5 is blown up by the high-pressure gas, and the TV casing gradually separates from the supporting surface and begins to float. Then the motor 201 is driven in the reverse direction, so that the threaded rod 203 can be reversed, and then the support frame 302 is driven to move to the left through the threaded sleeve 204 and the support plate 301, thereby driving the suspended TV casing to move to the left. After falling on the left end protection mechanism 5, the high-pressure air pump 3012 is turned off, so that the high-pressure gas slowly dissipates, so that the TV casing can fall on the left end protection mechanism 5; In the process of the TV housing being suspended in the air, the cylinder 4013 is driven so that the cylinder 4013 can push the opening plate 409 at the driving end to slide under the restriction of the connecting plate 406, and use the reaction force to push the other opening plate 409 to slide forward, so that the two opening plates 409 slide to the adjacent side, and then push the rotating plate 408 to rotate around the pin, thereby driving the concave plate 4010 to rotate, and driving the connecting plate 4011 to rotate through the concave plate 4010, and then the two connecting plates 409 are connected. 011 will drive a sector gear 4012 to rotate and mesh with each other for restriction, then the two rotating plates 408 will rotate around the pin and push the transmission column 407 to slide, as the two transmission columns 407 slide to the same side, the two sliding plates 402 are pushed to the same side, thereby driving the arc plate 404 to slide through the two fixed plates 403, so that the two arc plates 404 can protect the TV case to prevent insufficient high-pressure gas from being resisted by the two arc plates 404, thereby preventing the TV case from accidentally falling off.
