Description

Technical Field

[0001] This application relates to the field of factory construction, and in particular to cleanroom floor construction equipment and methods. Background Technology

[0002] Clean environments are essential in clean production processes, especially in electronics factories, medical device factories, cosmetic factories, and laboratories, so cleanrooms need to be built.

[0003] During the construction of cleanrooms, the floor is typically treated with epoxy resin to ensure high wear resistance and load-bearing capacity. Epoxy flooring also provides dustproof, anti-slip, and static electricity dissipation functions, and is easy to maintain and clean. However, during the epoxy resin spraying process, due to the irregularity of the walls, the spraying equipment cannot properly adapt the spraying path to certain locations, resulting in some areas where the floor and walls meet the spraying standards. Summary of the Invention

[0004] To facilitate operators in spraying coatings on areas where the floor and walls meet, this application provides a cleanroom floor coating device and its construction method.

[0005] The cleanroom floor construction device provided in this application adopts the following technical solution: A cleanroom floor construction device includes a vehicle body equipped with casters, a spray nozzle for spraying floor materials on the vehicle body, several support seats slidably mounted on the vehicle body, flexible belts on the support seats for restricting the movement path of the spray nozzles, the spray nozzles slidably mounted on the flexible belts, a first drive assembly for driving the support seats to move, a second drive assembly for driving the spray nozzles to move, and a first control assembly for controlling the movement distance of the support seats.

[0006] By adopting the above technical solution, when it is necessary to touch up the area where the ground and the wall meet, the operator moves the vehicle closer to the wall. Then, the first drive component drives the support base closer to the wall. After the nozzle moves to the spraying position with the support base, the first control component controls multiple support bases to stop moving in sequence, so that the positions of multiple support bases are adapted to the shape of the wall. As the flexible belt moves with the support base, the flexible belt is pulled into a shape adapted to the wall. Then, the first drive component drives the nozzle to move. The nozzle moves along the bending direction of the flexible belt, so that the nozzle can fully touch up the area where the wall and the ground meet. By setting up the flexible belt and the first control component, the support base moves under the action of the first drive component and pulls the flexible belt to move. The first control component controls multiple support bases to move to contact the wall. After the support base stops contacting the wall, the flexible belt is pulled into a shape adapted to the wall. Then, the nozzle moves along the bending direction of the flexible belt to adapt to the irregular spraying area.

[0007] Preferably, the first drive assembly includes a sleeve and a drive screw. The sleeve is slidably inserted into the vehicle body, and the end of the sleeve away from the vehicle body is fixedly connected to the support seat. The drive screw is rotatably installed in the vehicle body and passes into the sleeve. The drive screw is threadedly engaged with the sleeve. A third drive assembly for driving the drive screw to rotate is provided on the vehicle body.

[0008] By adopting the above technical solution, after the vehicle body moves to a certain position, the third drive component causes the drive screw to rotate, the drive screw rotation causes the sleeve to move, the sleeve movement causes the support seat to move, and after reaching the designated position, the first control component causes the support seat to stop moving, so that the flexible belt is pulled to form a shape that fits the wall.

[0009] Preferably, the third drive assembly includes a first motor and a first spur gear. The first motor is disposed in the vehicle body, the first spur gear is fixedly sleeved on the output end of the first motor, and a second spur gear is disposed on the drive screw. The first spur gear and the second spur gear mesh with each other.

[0010] By adopting the above technical solution, the first motor starts, drives the first spur gear to rotate, the rotation of the first spur gear causes the second spur gear to rotate, the rotation of the second spur gear causes the drive screw to rotate, the rotation of the drive screw causes the sleeve to move, and the movement of the sleeve causes the support to move.

[0011] Preferably, the first control component includes a telescopic rod and a control rod. One end of the telescopic rod is fixedly connected to the drive screw, and the other end of the telescopic rod is fixedly connected to a connecting rod. The second spur gear is fixedly sleeved on the connecting rod. The control rod is slidably disposed in the vehicle body. A first slide groove is provided in the vehicle body for sliding cooperation with the control rod. The end of the control rod located in the vehicle body is sleeved on the connecting rod. The connecting rod is rotatably connected to the control rod. A first return spring is fixedly connected to the control rod. The end of the first return spring away from the control rod is fixedly connected to the inner sidewall of the first slide groove. A second control component for controlling the movement of the control rod is provided on the vehicle body.

[0012] By adopting the above technical solution, during the process of the support seat moving towards the wall, after the support seat contacts the wall, the second control component causes the control rod to move, the control rod to move, the connecting rod to move, the connecting rod to move, the second spur gear to move, the second spur gear to move away from the first spur gear, and after the first spur gear disengages from the second spur gear, the first spur gear can no longer drive the second spur gear to rotate, thus stopping the movement of the drive screw and its corresponding support seat. The telescopic rod can ensure that the second spur gear can move while maintaining the driving effect on the drive screw.

[0013] Preferably, the second control component includes a push rod that abuts against the wall, the push rod slidably passing through the support base, a second return spring fixedly connected to the push rod, the end of the second return spring away from the push rod being fixedly connected to the support base, the end of the push rod away from the support base passing through the vehicle body, a plurality of first locking blocks passing through the push rod, a second sliding groove for sliding engagement of the first locking blocks being formed on the push rod, a third return spring fixedly connected to the first locking blocks, the end of the third return spring away from the first locking blocks being fixedly connected to the inner sidewall of the second sliding groove; A second locking block is inserted through the control rod, and a third sliding groove is opened inside the control rod for sliding cooperation with the second locking block. A fourth return spring is fixedly connected to the second locking block, and the end of the fourth return spring away from the second locking block is fixedly connected to the inner side wall of the third sliding groove. The first locking block can abut against the second locking block. The side walls of the first locking block and the second locking block that are close to each other are provided with inclined surfaces. A third control component for controlling the movement of the second locking block is provided on the vehicle body.

[0014] By adopting the above technical solution, the first motor drives the first spur gear to rotate, the rotation of the first spur gear causes the second spur gear to rotate, the rotation of the second spur gear causes the connecting rod to rotate, the rotation of the connecting rod causes the telescopic rod to rotate, the rotation of the telescopic rod causes the drive screw to rotate, the rotation of the drive screw causes the sleeve to move, the movement of the sleeve causes the support seat to move, and when the support seat moves towards the wall, the push rod moves with the support seat. At this time, the first locking block and the inclined surface of the second locking block are in contact. The second locking block pushes the first locking block to slide in the second slide groove and compresses the third return spring. The first locking block will not cause the second locking block to move. The push rod first contacts the wall, and the wall pushes the push rod to move until the support seat and the push rod simultaneously contact the wall. At this time, the push rod moves towards the vehicle body. Since the first and second locking blocks are not in contact at an inclined plane at this time, the first locking block will push the second locking block to move. The movement of the second locking block causes the control lever to move, which in turn causes the connecting rod to move. The movement of the connecting rod causes the second spur gear to move, and the second spur gear moves away from the first spur gear. At this time, the support seat stops moving. When the support seat needs to move towards the vehicle body, the third control component releases the restriction on the second locking block. The second locking block moves under the action of the fourth return spring. The second locking block moves within the third slide and away from the first locking block. At this time, the control lever returns to the initial position under the action of the first return spring, and the second spur gear re-meshes with the first spur gear. When the first motor reverses, the support seat can return to the initial position.

[0015] Preferably, the third control component includes a first cylinder and a limiting rod. The first cylinder is fixedly connected to the vehicle body, and a support plate is fixedly connected to the output end of the first cylinder. The limiting rod is fixedly connected to the support plate, and the end of the limiting rod away from the support plate passes through the control rod. The end of the limiting rod inside the control rod abuts against the second locking block. The sidewalls of the limiting rod and the second locking block that are close to each other are provided with inclined surfaces. The limiting rod slides in cooperation with the inner sidewall of the third slide groove.

[0016] By adopting the above technical solution, when the support seat needs to move towards the vehicle body, the first cylinder drives the support plate to move. The movement of the support plate causes the limiting rod to move. The limiting rod moves away from the second locking block. After the second locking block loses the limiting effect of the limiting rod, it moves under the action of the fourth return spring. The second locking block moves in the third slide groove and moves away from the first locking block. At this time, the control rod returns to the initial position under the action of the first return spring. The second spur gear re-meets the first spur gear. When the first motor reverses, the support seat can return to the initial position. When the second locking block needs to re-contact the first locking block, the first cylinder starts. The first cylinder pushes the support plate and the limiting rod to move towards the second locking block. The second locking block moves under the action of the inclined surface of the limiting rod. The second locking block moves in the third slide groove to the outside of the control rod and can re-contact the first locking block.

[0017] Preferably, a first auxiliary wheel is fixedly connected to the support base, the first auxiliary wheel passes through the flexible belt, a first limiting groove is provided in the flexible belt for sliding cooperation with the first auxiliary wheel, a sliding seat is slidably disposed on the flexible belt, the nozzle is disposed on the sliding seat, a second limiting groove is provided on the flexible belt for sliding cooperation with the sliding seat, a take-up wheel is rotatably mounted on the vehicle body, a torsion spring is provided at the connection between the vehicle body and the take-up wheel, and the end of the flexible belt away from the support base is wound around the take-up wheel.

[0018] By adopting the above technical solution, the first auxiliary wheel can help the support seat to pull the shape of the flexible belt and reduce wear. The second limiting groove can improve the stability of the sliding seat when it moves. The winding wheel and the torsion spring can keep the flexible belt in a taut state. When the flexible belt is pulled, part of the flexible belt on the winding wheel extends out to prevent the flexible belt from breaking due to its length under the traction of the support seat.

[0019] Preferably, the second driving assembly includes a driving wheel, a second auxiliary wheel is rotatably mounted on the sliding seat, the second auxiliary wheel slides in cooperation with the second limiting groove, the driving wheel is disposed on the sliding seat, a first tensioning wheel is slidably disposed on the sliding seat, the driving wheel is fixedly sleeved on the first tensioning wheel, a second motor is disposed on the sliding seat, a first pulley is fixedly sleeved on the output end of the second motor, a second tensioning wheel is disposed on the sliding seat, a transmission belt is wound around the first tensioning wheel, the first pulley, and the second tensioning wheel, and a third motor is fixedly connected to the sliding seat, the output end of the third motor is fixedly connected to the nozzle.

[0020] By adopting the above technical solution, after the support seat moves, the second motor starts and drives the first pulley to rotate. The rotation of the first pulley causes the transmission belt to run, which in turn causes the first tension wheel and the second tension wheel to rotate. The rotation of the first tension wheel causes the drive wheel to rotate, which in turn causes the sliding seat to move along the second limiting groove. The nozzle then moves to spray the recoating area. The first tension wheel can keep the drive wheel and the second limiting groove in close contact to prevent the sliding seat from slipping during movement. The second auxiliary wheel can support the sliding seat to prevent it from jamming. The third motor can control the angle of the nozzle to adapt to different working conditions.

Start the first motor until all support seats stop moving, start the second motor to move the nozzle along the flexible belt, and spray EPOXY multiple times on the recoating area until the standard is met.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a flexible belt and a first control component, the support base moves under the action of the first drive component and pulls the flexible belt to move. The first control component controls multiple support bases to move to contact the wall.

Then the nozzle moves along the bending direction of the flexible belt to adapt to the irregular spraying area. 2. By setting up a take-up reel, the take-up reel and torsion spring can maintain the tension of the flexible belt. When the flexible belt is pulled, part of the flexible belt on the take-up reel extends out to prevent the flexible belt from breaking due to its length under the traction of the support seat. 3. By setting the first tensioning wheel, the first tensioning wheel can keep the drive wheel in close contact with the second limiting groove, preventing the sliding seat from slipping during movement.
