Description

Technical Field

[0001] The invention relates to the technical field of vacuum coating, and in particular to a vacuum coating device with an intelligent temperature control function. Background Art

[0002] Vacuum coating equipment is a device used to form a thin film on the surface of an object. It is based on physical vapor deposition (PVD), chemical vapor deposition (CVD) or atomic layer deposition (ALD) technologies to deposit specific materials on the surface of an object in a vacuum environment to form a thin film. Vacuum coating technology is widely used in optical lenses, solar panels, laser devices, semiconductor devices, integrated circuits, flat panel displays, jewelry, automobiles, medical devices and other fields. It can improve the performance of products, such as light transmittance, reflectivity, wear resistance, corrosion resistance, etc., while meeting the needs of personalized customization.

[0003] When vacuum coating some pipe-like workpieces, it is necessary to manually disassemble and assemble the rotating fixed components in the vacuum coating device, and to install the pipes on the rotating fixed components one by one. After coating, manual unloading is required, which is very labor-intensive. In addition, when the pipes are not installed stably, they are easily thrown off when the rotating fixed components rotate, causing damage to other components. When coating some special pipes, both ends need to be sealed. If the manual sealing is not dense, it will also cause batches of finished products to be unqualified. Summary of the invention

[0004] The purpose of the present invention is to provide a vacuum coating device with intelligent temperature control function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vacuum coating device with intelligent temperature control function, comprising a base, a vacuum coating component is installed on the base, an electric lifting platform is installed on the base, and a dust removal and feeding device is symmetrically installed on the electric lifting platform; the vacuum coating component comprises a coating tank body and a first electric telescopic rod, the first electric telescopic rod is installed on the base, a coating mechanism is provided in the coating tank body, a vacuum component is provided on the coating tank body, a moving door is symmetrically and slidably installed on the coating tank body, the output shaft of the first electric telescopic rod is connected to the moving door, a slide rail is installed between the coating tank body and the base, an electric slider is slidably installed on the slide rail, a drive motor is installed on the electric slider, a rotating rod is installed on the output shaft of the drive motor, and a number of fixed components are installed on the rotating rod.

[0006] A control system is installed in the base, which is used to control the entire vacuum coating device. A temperature control component is provided in the coating tank, which is used to intelligently adjust the temperature in the coating tank. The coating mechanism is used to coat the pipes. The vacuum component is used to evacuate the coating tank.

[0007] After the pipe fittings are installed, the control system turns on the electric slider, which drives the drive motor, the rotating rod and the fixed component to move into the coating tank body, and turns on the first electric telescopic rod. The output shaft of the first electric telescopic rod drives the moving door to slide and close. After that, the control system uses the vacuum component to evacuate the coating tank body. When the coating tank body gradually enters a vacuum state, the air pressure decreases, and a pressure difference is generated inside and outside the sealing airbag. The sealing airbag expands to seal both ends of the pipe fitting to prevent the inner wall of the pipe fitting from being coated. At the same time, the pipe fitting is also fixed for a second time to prevent the pipe fitting from being dislocated or slipping due to the influence of centrifugal force when the rotating rod rotates, causing damage to other components. The control system uses the temperature control component to adjust the temperature, and then turns on the drive motor. The drive motor drives the rotating rod to rotate, and the rotating rod drives the pipe fittings on the fixed component to rotate. The control system turns on the coating mechanism to coat the pipe fittings. After the coating is completed, the movable door is opened, and the control system controls the pipe fitting to move to the dust removal and feeding device, and the electromagnetic ring is turned on. The electromagnetic ring absorbs and shrinks the adsorption sheet, and the adsorption sheet drives the clamping block to retract, so that the clamping block is disconnected from the clamping end. The ball generates pressure on the inclined surface of the top cone under the elastic force of the second spring. Under the squeezing of several balls, the top cone drives the fixed push rod to slide in the opposite direction and reset, and the inner support assembly is reset accordingly and disconnects the fixation to the pipe fitting.

[0008] Furthermore, the fixed component includes a fixed shell, which is installed on the rotating rod, on which a blocking airbag is symmetrically installed, on which a plurality of inner support components are slidably installed, on which a positioner is installed, and in which a fixed push rod is slidably installed.

[0009] Furthermore, a plurality of top cones are installed on the fixed push rod, a first push head is provided at one end of the fixed push rod, and a clamping terminal is installed at the other end of the fixed push rod.

[0010] Furthermore, the positioning device includes an adsorption sheet and an electromagnetic ring. The electromagnetic ring is installed in a fixed shell. The adsorption sheet is slidably installed in the fixed shell. A card block is installed on the adsorption sheet. A positioning spring is installed between the adsorption sheet and the electromagnetic ring.

[0011] Furthermore, the internal support assembly includes a sliding shell, which is slidably installed on the fixed shell, with balls installed on the sliding shell, a second spring installed between the sliding shell and the fixed shell, an internal support rod slidably installed in the sliding shell, a first spring installed between the internal support rod and the fixed shell, and an internal support block installed on the internal support rod.

[0012] After the dust removal of the pipe fitting is completed, the second electric telescopic rod drives the pipe fitting to move through the installation end head and is sleeved on the fixed assembly. The second push head pushes the fixed push rod through the first push head, and the fixed push rod slides, and the top cone on it slides to the position of the inner support assembly. The inclined surface on the top cone gradually squeezes the sliding outer shell through the ball bearing, and the sliding outer shell slides outward on the fixed outer shell. The inner support rod slides with the sliding outer shell and drives the inner support block to resist the inner wall of the pipe fitting. The inner support block supports and fixes the inner wall of the pipe fitting to complete the preliminary fixation of the pipe fitting. The first spring allows the inner support rod to slide elastically in the sliding outer shell to automatically adapt to pipe fittings of different diameters. When the clamping end on the fixed push rod slides to the position of the clamping device, the clamping end squeezes the clamping block, and the clamping block retracts after being compressed to overcome the elastic force of the clamping spring. When the clamping end slides over the clamping block, the clamping block rebounds under the elastic force of the clamping spring, and the clamping block clamps the clamping end, fixes the fixed push rod, and thus realizes the installation of the pipe fittings. The control system turns on the electric lifting platform, and the electric lifting drives the dust removal and feeding device to install the pipe fittings on the fixed components from bottom to top. After that, the control system uses the drive motor to drive the rotating rod to rotate, so that the other fixed components on the rotating rod rotate to the position of the dust removal and feeding device, and repeats the previous operation to install the next set of pipe fittings.

[0013] Furthermore, the dust removal feeding device includes a feeding shell, a mounting assembly is installed on the feeding shell, a first cylinder is installed on the feeding shell, a first limit block is slidably installed on the feeding shell, a feeding spring is installed between the first limit block and the feeding shell, a second cylinder is installed on the feeding shell, and the output shaft of the second cylinder passes through the feeding shell and is installed with a second limit block.

[0014] When unloading is required, the control system turns on the first cylinder, the output shaft of the first cylinder extends out and pushes the pipe fitting, the pipe fitting squeezes the first limit block, the first limit block overcomes the elastic force of the unloading spring after being compressed and retracts into the feeding shell, the pipe fitting passes the first limit block and enters the unloading bin, and is blocked by the second limit block. At this time, the pipe fitting is aligned with the installation end, and the pipe fitting is in place. After that, the output shaft of the first cylinder retracts, the pipe fitting in the storage bin falls, and under the action of the unloading spring, the first limit block pops up; Furthermore, a finished product bin is provided in the feeding shell, a storage bin is provided in the feeding shell, a lower feeding bin is provided in the feeding shell, the finished product bin and the storage bin are connected through the lower feeding bin, a dust removal assembly is installed on one side of the feeding shell, a cylinder is installed on the other side of the feeding shell, and an installation assembly is installed on the cylinder.

[0015] The storage bin is used to store the pipes to be coated, and the first limit block and the second limit block are used to block the pipes to prevent them from sliding.

[0016] The installation component repeats the previous operation to fix the coated pipe fittings and send them back to the unloading bin. The control system starts the second cylinder, and the output shaft of the second cylinder drives the second limit block to retract. After the pipe fittings lose their obstruction, they slide to the finished product bin, and this cycle is repeated to complete the fully automatic coating production of the pipe fittings.

[0017] Furthermore, the mounting assembly includes a second electric telescopic rod, which is mounted on the cylinder. A mounting end is rotatably mounted on the output shaft of the second electric telescopic rod, and the mounting end is slidably mounted in the cylinder.

[0018] Furthermore, the installation end includes an end block, a transmission bead is installed on the end block, a second push head is installed on the end block, an electromagnetic block is installed in the end block, a positioning slide rod is slidably installed in the end block, a permanent magnet block is installed at one end of the positioning slide rod, a fixed block is installed at the other end of the positioning slide rod, the permanent magnet block is located around the electromagnetic block, a reset spring is installed between the permanent magnet block and the end block, and the end block is installed on the output shaft of the second electric telescopic rod.

[0019] The control system energizes the electromagnetic block, causing the electromagnetic block to generate a magnetic field that repels the permanent magnet. The permanent magnet is repelled and drives the positioning slide bar to slide outward. The positioning slide bar drives the fixed block to slide outward to press against the inner wall of the pipe fitting. Then, by changing the size of the magnetic field of the electromagnetic block, the displacement of the permanent magnet is changed to achieve fixation of pipe fittings of different diameters. After the pipe fitting is installed, the control system cuts off the power supply to the electromagnetic block, the repulsive force on the permanent magnet disappears, and under the action of the reset spring, the permanent magnet drives the fixed block to slide in the opposite direction and reset through the positioning slide bar, and disengages from the pipe fitting.

[0020] After the pipe fitting is in place, the control system turns on the second electric telescopic rod, and the output shaft of the second electric telescopic rod drives the installation end head to extend forward, so that the installation end head fixes the pipe fitting. Afterwards, the output shaft of the second electric telescopic rod drives the installation end head to continue to extend forward, and the installation end head drives the pipe fitting into the dust removal inner cylinder, and the dust removal assembly removes dust from the pipe fitting.

[0021] Furthermore, the dust removal assembly includes an outer dust removal cylinder and an inner dust removal cylinder. The outer dust removal cylinder is installed on one side of the feeding shell. An end ring is installed between the outer dust removal cylinder and the inner dust removal cylinder. The outer dust removal cylinder, the inner dust removal cylinder and the end ring constitute a dust removal chamber. The inner dust removal cylinder is provided with a spiral groove. The size of the spiral groove matches the size of the transmission bead. The inner dust removal cylinder is provided with an exhaust gap. An exhaust device is installed at the bottom end of the outer dust removal cylinder. The exhaust device is connected to the dust removal chamber through a pipeline.

[0022] The exhaust device is used to extract the air in the dust removal chamber to generate negative pressure in the dust removal chamber. When the pipe passes through the dust removal inner cylinder, the dust removal chamber sucks the dust attached to the surface of the pipe into the dust removal chamber through the exhaust slit to achieve the dust removal effect. After the installation end drives the pipe into the dust removal inner cylinder, as the installation end moves forward further, the transmission beads gradually slide along the spiral groove, and the transmission beads drive the entire installation end to rotate on the output shaft of the second electric telescopic rod. The installation end drives the pipe to rotate in the dust removal inner cylinder, so that the exhaust slit can remove dust from all areas on the surface of the pipe without dead angles.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. When installing the pipe fittings, the second pusher on the installation end is used to synchronously drive the fixed push rod to slide, so that the inner support component clamps the pipe fittings, realizing the linkage between the installation component and the fixed component, and achieving the purpose of automatically fixing the pipe fittings; the electromagnetic ring is used to absorb and shrink the adsorption sheet, so that the clamping block disconnects the fixation of the clamping end, and the top cone drives the fixed push rod to slide back and reset, and the inner support component is reset and disconnects the fixation of the pipe fittings, realizing the purpose of automatically separating the fixed component from the pipe fittings; the electric lifting device is used to drive the dust removal and feeding device to move up and down, and the driving motor is used to drive the fixed component to rotate, and the two cooperate to realize the overall installation of the pipe fittings. The first spring allows the inner support rod to slide elastically in the sliding shell to achieve adaptive fixation of pipe fittings of different diameters.

[0024] 2. The air extraction device is used to extract the air in the dust removal chamber to generate negative pressure in the dust removal chamber. When the pipe passes through the dust removal inner cylinder, the dust removal chamber sucks the dust attached to the surface of the pipe into the dust removal chamber through the air extraction slit to achieve the dust removal effect. After the installation end drives the pipe into the dust removal inner cylinder, the transmission bead drives the entire installation end to rotate on the output shaft of the second electric telescopic rod, and the installation end drives the pipe to rotate in the dust removal inner cylinder, so that the air extraction slit can remove dust from all areas on the surface of the pipe without dead angles.

[0025] 3. The control system energizes the electromagnetic block, so that the permanent magnet block is repelled and drives the positioning slide bar to slide outward. The positioning slide bar drives the fixed block to slide outward, presses against the inner wall of the pipe fitting, and then changes the magnetic field size of the electromagnetic block and the displacement of the permanent magnet to achieve the effect of fixing pipe fittings of different diameters.

[0026] 4. The first limit block is used in conjunction with the first cylinder to realize automatic feeding of pipe fittings, and the second cylinder is used in conjunction with the second limit block to realize unloading and collection of finished pipe fittings.

[0027] 5. Use the electric slider to drive the drive motor, the rotating rod and the fixed assembly to move into the coating tank body, and use the first electric telescopic rod to drive the movable door to slide and close, so as to realize the automatic opening and closing of the coating tank body and the automatic disassembly of the rotating rod and the fixed assembly; when the coating tank body gradually enters a vacuum state, the sealing airbag automatically expands to seal both ends of the pipe fitting to prevent the inner wall of the pipe fitting from being coated, and at the same time, the pipe fitting is also fixed for a second time to prevent the pipe fitting from being dislocated or slipping due to the centrifugal force when the rotating rod rotates, causing damage to other components.

The dust removal outer cylinder 3141, the dust removal inner cylinder 3142 and the end ring 3143 constitute a dust removal chamber 3144.

[0045] The working principle of the present invention is as follows: when unloading is required, the control system turns on the first cylinder 33, the output shaft of the first cylinder 33 extends out and pushes the pipe, the pipe squeezes the first limit block 34, the first limit block 34 overcomes the elastic force of the unloading spring 37 after being compressed and retracts into the feeding housing 31, the pipe passes over the first limit block 34 and enters the unloading bin 312, and is blocked by the second limit block 36. At this time, the pipe is aligned with the installation end 322, and the pipe is in place. After that, the output shaft of the first cylinder 33 retracts, the pipe in the storage bin 311 falls, and under the action of the unloading spring 37, the first limit block 34 pops up; After the pipe is in place, the control system turns on the second electric telescopic rod 321, and the output shaft of the second electric telescopic rod 321 drives the mounting end 322 to extend forward, so that the mounting end 322 fixes the pipe. Afterwards, the output shaft of the second electric telescopic rod 321 drives the mounting end 322 to continue to extend forward, and the mounting end 322 drives the pipe into the dust removal inner cylinder 3142, and the dust removal assembly 314 removes dust from the pipe.

[0046] After the dust removal of the pipe is completed, the second electric telescopic rod 321 drives the pipe to move and is sleeved on the fixed assembly 28 through the installation end 322, and the second push head 3224 pushes the fixed push rod 282 through the first push head 2821, and the fixed push rod 282 slides, and the top cone 2822 thereon slides to the position of the inner support assembly 284, and the inclined surface on the top cone 2822 gradually squeezes the sliding shell 2842 through the ball 2845, and the sliding shell 2842 slides outward on the fixed shell 281, and the inner support rod 2841 slides with the sliding shell 2842 and drives the inner support block to resist the inner wall of the pipe, and the inner support block supports and fixes the inner wall of the pipe to complete the preliminary fixation of the pipe, and the first spring 2843 allows the inner support rod 2841 to slide elastically in the sliding shell 2842 to automatically adapt to pipes of different diameters. When the clamping end 2823 on the fixed push rod 282 slides to the position of the clamping device 283, the clamping end 2823 squeezes the clamping block 2831, and the clamping block 2831 retracts after being compressed to overcome the elastic force of the clamping spring 2834. When the clamping end 2823 slides over the clamping block 2831, the clamping block 2831 rebounds under the elastic force of the clamping spring 2834, and the clamping block 2831 clamps the clamping end 2823, and the fixed push rod 282 is fixed, thereby realizing the installation of the pipe fittings. The control system turns on the electric lifting platform, and the electric lifting drives the dust removal and feeding device 3 to install the pipe fittings on the fixed assembly 28 from bottom to top. After that, the control system uses the driving motor 25 to drive the rotating rod 26 to rotate, so that the other fixed assemblies 28 on the rotating rod 26 rotate to the position of the dust removal and feeding device 3, and repeats the previous operation to install the next group of pipe fittings.

[0047] After the pipe fittings are installed, the control system turns on the electric slider 24, and the electric slider 24 drives the drive motor 25, the rotating rod 26 and the fixing assembly 28 to move into the coating tank 21, and turns on the first electric telescopic rod 27. The output shaft of the first electric telescopic rod 27 drives the movable door 22 to slide and close. After that, the control system uses the vacuum assembly to evacuate the coating tank 21. When the coating tank 21 gradually enters a vacuum state, the air pressure decreases, and a pressure difference is generated inside and outside the sealing airbag 285. The sealing airbag 285 expands to block both ends of the pipe fitting to prevent the inner wall of the pipe fitting from being coated. At the same time, the pipe fitting is also fixed for a second time to prevent the pipe fitting from being dislocated or slipping due to the centrifugal force when the rotating rod 26 rotates, causing damage to other components; the control system uses the temperature control assembly to adjust the temperature, and then turns on the drive motor 25. The drive motor 25 drives the rotating rod 26 to rotate, and the rotating rod 26 drives the pipe fittings on the fixing assembly 28 to rotate. The control system turns on the coating mechanism to coat the pipe fittings. After the coating is completed, the movable door 22 is opened, and the control system controls the pipe fitting to move to the dust removal and feeding device 3, and the electromagnetic ring 2833 is turned on. The electromagnetic ring 2833 absorbs and shrinks the adsorption sheet 2832, and the adsorption sheet 2832 drives the clamping block 2831 to retract, so that the clamping block 2831 disconnects the fixation of the clamping end 2823, and the ball 2845 generates pressure on the inclined surface of the top cone 2822 under the elastic force of the second spring 2844. Under the squeezing of a number of balls 2845, the top cone 2822 drives the fixed push rod 282 to slide in the opposite direction and reset, and the inner support assembly 284 is reset accordingly and disconnects the fixation to the pipe fitting.

[0048] The installation component 32 repeats the previous operation to fix the coated pipe fittings and send them back to the unloading bin 312. The control system starts the second cylinder 35. The output shaft of the second cylinder 35 drives the second limit block 36 to retract. After the pipe fittings are no longer blocked, they slide to the finished product bin 313. This cycle is repeated to complete the fully automatic coating production of the pipe fittings.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
