Description

Technical Field

[0001] This application relates to the field of feeding machine technology, and in particular to a visually guided LCD module feeding machine and its usage method. Background Technology

[0002] An LCD module is a complete display component that integrates an LCD panel, driving circuit, backlight system, connectors, etc. It is the core component for image display in electronic devices. When producing LCD modules, a feeding machine is needed for feeding operations. Visual guidance feeding machines are commonly used for feeding LCD modules. A visual guidance LCD module feeding machine is an automated device specifically designed for the precise feeding and positioning of LCD modules.

[0003] When using a vision-guided LCD module loading machine, an industrial camera photographs and positions the material on the support plate. A linear guide rail moves a vacuum suction cup, which then picks up the material and places it precisely on the conveyor belt. Each time the vacuum suction cup picks up or puts down a material, the slide block of the linear guide rail moves back and forth on the rail. This high-frequency reciprocating movement causes the lubricating oil film on the rail to thin or even break, leading to direct metal-to-metal contact. This results in wear between the rail and the slide block, affecting the accurate positioning of the slide block. Summary of the Invention

[0004] This application proposes a visually guided LCD module feeding machine and its usage method, which has the advantage of preventing the rupture of the lubricating oil film on the slide rail, and solves the problems of oil film rupture due to high-frequency reciprocating movement of the slide block on the slide rail and inaccurate positioning caused by wear between the slide rail and the slide block.

[0005] To achieve the above objectives, this application adopts the following technical solution: a vision-guided LCD module loading machine and its usage method, comprising a housing, a support plate, a linear guide rail, a support column, a cross column, an industrial camera, and a control device. The linear guide rail includes a slide rail and a slide block. The support column has an installation groove, and an oil dripping mechanism is provided in the installation groove. The oil dripping mechanism includes:

[0006] The rotating shaft has two ends that can be inserted into the sidewalls of the mounting slot, and one end that extends out of the sidewall of the support column.

[0007] A rotating block is fixedly sleeved on a rotating shaft located in an installation groove. The rotating block is in rotatable sealing contact with the inner wall of the installation groove. A liquid groove is opened on the side wall of the rotating block.

[0008] The mounting groove above the rotating block is filled with lubricating oil. The housing is equipped with a drive mechanism to drive the rotating shaft to rotate. The support column and slide at the bottom of the mounting groove are provided with oil leakage holes that connect to the bottom of the mounting groove.

[0009] Preferably, the drive mechanism includes:

[0010] An inclined plate circular block is fixedly sleeved on one end of the rotating shaft that extends out of the side wall of the support column;

[0011] A fixed block is fixedly connected to the housing in the sliding direction of the inclined plate circular block, and a limit groove is provided at the end of the fixed block;

[0012] The drive board is hinged at one end to the limiting groove.

[0013] Preferably, the side walls of the two support columns are provided with transverse grooves, and an electromagnetic block is fixedly installed in the transverse groove. A moving mechanism for intermittently energizing the electromagnetic block is provided in the mounting groove above the lubricating oil level. A horizontal groove is provided inside the transverse column, and the horizontal groove contains:

[0014] Permanent magnet blocks are slidably sealed at both ends of the horizontal groove;

[0015] The return spring has its two ends connected to the permanent magnet and the electromagnetic block, respectively.

[0016] Conductor block III is embedded in the lower wall at both ends of the horizontal groove;

[0017] The limiting block is fixedly installed on the horizontal groove between the two conductor blocks III;

[0018] Conductor block IV is fixedly installed on the upper wall of the horizontal groove between the two limiting blocks.

[0019] Preferably, conductor blocks I are symmetrically embedded in the sidewalls of the mounting groove, and the moving mechanism includes:

[0020] The connecting column is located in the mounting groove above the lubricating oil level;

[0021] Several sliders are fixedly fitted onto the connecting post;

[0022] Conductor block II is symmetrically embedded in the side wall of the slider;

[0023] The horizontal groove between the two permanent magnet blocks is filled with conductive fluid. Conductor block I, conductor block II and electromagnetic block are electrically connected. Conductor block III, conductor block IV, conductive fluid and control device are electrically connected.

[0024] Preferably, when the electromagnetic block is energized, it generates a magnetic force that repels the permanent magnet block.

[0025] Preferably, a counterweight is fixedly connected to the top of the connecting column, and the bottom of the counterweight is slidably and sealed within the mounting groove.

[0026] Preferably, an exhaust valve and a replenishing valve are embedded in the horizontal column above the horizontal groove. The exhaust valve and the replenishing valve are connected to the horizontal groove. The top end of the exhaust valve is connected to a connecting pipe. The other end of the connecting pipe is movably connected to the top end of the inner wall of the housing. The end of the connecting pipe connected to the inner wall of the housing is fixedly connected to a nozzle. The jet direction of the nozzle is towards the lens of the industrial camera.

[0027] Preferably, the exhaust valve and the air replenishment valve are one-way valves, the flow direction of the exhaust valve is from inside the horizontal groove to the connecting pipe, and the flow direction of the air replenishment valve is from outside to inside the horizontal groove.

[0028] The present invention also proposes a method for using a vision-guided liquid crystal display module loading machine as mentioned above, comprising the following steps:

[0029] S1. When the slide block and support column move toward the fixed block and drive plate, the inclined plate of the inclined plate block on the support column hits the drive plate, causing the drive plate to push the inclined plate block, the rotating shaft and the rotating block to rotate. The liquid groove on the rotating block drives the lubricating oil to rotate. When the liquid groove on the rotating block rotates to the bottom, the lubricating oil in the liquid groove drips onto the slide rail through the oil leakage hole connected to the bottom of the mounting groove.

[0030] S2. The lubricating fluid above the rotating block gradually decreases, and the connecting column, slider and conductor block II on the surface of the lubricating fluid gradually descend. During the descent, conductor block II on the side wall of the slider intermittently contacts conductor block I. The electromagnetic block is energized to generate a magnetic force that repels the permanent magnet block. The permanent magnet block squeezes the conductive fluid in the horizontal tank, causing the liquid level of the conductive fluid to rise.

[0031] S3. When the horizontal column does not tilt, the conductive liquid rising in the horizontal tank electrically connects the conductor blocks IV at both ends. When the horizontal column tilts, the conductive liquid rising in the horizontal tank cannot simultaneously contact the conductor blocks IV at both ends, thus causing the control device to display an alarm, indicating that the horizontal column has tilted.

[0032] S4. When the permanent magnet blocks squeeze the conductive liquid in the horizontal tank, they also squeeze the gas above the conductive liquid, compressing the gas in the horizontal tank. The gas enters the connecting pipe through the exhaust valve, and the gas in the connecting pipe is sprayed onto the lens of the industrial camera through the nozzle, thereby cleaning the lens of the industrial camera by air jet.

[0033] This application has the following beneficial effects:

[0034] 1. The visual guidance LCD module feeding machine provided in this application, when the slide moves the support column and the cross column back and forth, the inclined plate block on the support column is pushed by the drive plate on the inner wall of the housing, causing the inclined plate block to drive the rotating shaft and the rotating block to rotate. Under long-term cyclic action, the lubricating oil above the rotating block enters the bottom of the rotating block through the liquid groove, adding lubricating oil between the slide and the slide rail, preventing the lubricating oil film on the slide rail from being lost and thinned, thereby avoiding friction between the slide and the slide rail to avoid wear that affects the accurate positioning of the slide.

[0035] 2. The visually guided LCD module loading machine provided in this application reduces the lubricating oil above the rotating block, causing the connecting column, slider, conductor block II, and counterweight block to move downwards. The moving conductor block II contacts conductor block I, energizing the electromagnetic block. The electromagnetic block generates a magnetic force that repels the permanent magnet block, causing the permanent magnet block to squeeze the conductive liquid in the horizontal tank. This prevents the conductive liquid from connecting to the conductor blocks III on both sides. When the horizontal column is horizontal, the conductive liquid connects to the conductor blocks IV on both sides. When the horizontal column tilts to a certain extent, the conductive liquid stops connecting. This allows for the detection of whether the horizontal column is horizontal, preventing vibrations caused by the vacuum suction cup adsorbing raw materials, which could loosen the bolts at both ends of the horizontal column and cause it to tilt. This avoids affecting the vacuum suction cup's adsorption and positioning of the raw materials.

[0036] 3. The visual guidance LCD module feeding machine provided in this application uses the magnetic force generated by the electromagnetic block to repel the permanent magnet block, which in turn squeezes the conductive liquid in the horizontal tank and squeezes the gas in the horizontal tank. The gas in the horizontal tank is then sprayed out through the connecting pipe and nozzle to clean the lens of the industrial camera by air jet, preventing the lens of the industrial camera from being contaminated and affecting the accurate positioning of the raw materials.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] Example 1

[0050] Please see Figures 1-3This embodiment proposes a vision-guided LCD module loading machine, including a housing 1, a support plate 2, linear guide rails 3, support columns 4, cross columns 5, vacuum suction cups 6, transport suction cups 7, a conveyor belt 8, an industrial camera 9, and a control device (the control device is an existing device and is not shown in the figure). The support plate 2 is fixedly installed on the inner wall of the housing 1. The support plate 2 is horizontally arranged. Two sets of parallel linear guide rails 3 are fixedly installed on the top of the support plate 2 along the length direction of the housing 1. The two sets of linear guide rails 3 are respectively close to the two sides of the housing 1. The linear guide rails 3 include slide rails 31 and slide blocks 32. The slide rails 31 are fixedly installed on the support plate 2, and the slide blocks 32 are slidably installed. On the slide rail 31, the top of the slide block 32 is fixedly connected to a support column 4. The tops of the opposite side walls of the two support columns 4 are fixedly connected to the two ends of the same horizontal column 5. A drive device is installed on one side of the horizontal column 5. A vacuum suction cup 6 is slidably installed on the side wall of the horizontal column 5. The drive device is used to drive the vacuum suction cup 6 to move on the horizontal column 5. A transport suction cup 7 is slidably installed on the other side of the horizontal column 5. A conveyor belt 8 is fixedly installed on the top of the support plate 2 away from the linear guide rail 3. The conveyor belt 8 is used to transport the raw material placed on the vacuum suction cup 6. An industrial camera 9 is fixedly installed on the top wall of the housing 1. The industrial camera 9 is used to take pictures and position the raw material between the two linear guide rails 3.

[0051] Please see Figures 1-8 A longitudinal mounting groove 41 is provided in the middle of the support column 4. An oil dripping mechanism 42 is provided in the mounting groove 41. The oil dripping mechanism 42 includes a rotating shaft 421, a rotating block 422 and a liquid tank 423. Both ends of the rotating shaft 421 are movably inserted into the side wall of the mounting groove 41, and one end of the rotating shaft 421 extends through to the outside of the support column 4. The rotating block 422 is fixedly sleeved on the rotating shaft 421 in the mounting groove 41. The rotating block 422 is in rotatable sealing contact with the inner wall of the mounting groove 41. The mounting groove 41 above the rotating block 422 is filled with lubricating oil. A liquid tank 423 is provided on the side wall of the rotating block 422. A drive mechanism for driving the oil dripping mechanism 42 to rotate is provided in the housing 1. An oil leakage hole communicating with the bottom of the mounting groove 41 is provided on the support column 4 and the slide block 32 at the bottom of the mounting groove 41. After the rotating block 422 rotates 180°, the lubricating oil inside the liquid tank 423 drips onto the slide rail 31 through the oil leakage hole.

[0052] The driving mechanism includes a sloping plate block 431, a fixed block 432, and a driving plate 434. The sloping plate block 431 is fixedly sleeved on one end of the rotating shaft 421 that extends through to the outside of the support column 4. A fixed block 432 is fixedly connected to the side wall of the housing 1 in the sliding direction of the sloping plate block 431, and the fixed block 432 is positioned higher than the sloping plate block 431. A limiting groove 433 is formed at the end of the fixed block 432 facing the sloping plate block 431. The driving plate 434 is hinged within this limiting groove 433. In its initial state, the bottom end of the driving plate 434 is vertically downward, and the driving plate 434 can rotate 90° counterclockwise relative to the fixed block 432. The bottom end of the movable plate 434 is at the same height as the uppermost inclined plate of the inclined plate block 431. When the slide block 32 drives the support column 4 and the inclined plate block 431 to move towards the fixed block 432 and the drive plate 434, the drive plate 434 pushes the inclined plate of the inclined plate block 431 until the drive plate 434 passes over the inclined plate block 431, causing the inclined plate block 431 to rotate. When the slide block 32 drives the support column 4 and the inclined plate block 431 to move away from the fixed block 432 and the drive plate 434, since the drive plate 434 can rotate counterclockwise, the inclined plate block 431 will not be pushed from the other side of the inclined plate block 431 by the drive plate 434, causing the inclined plate block 431 to rotate in the opposite direction.

[0053] When using the visually guided LCD module loading machine, the slide block 32 drives the support column 4 and the cross column 5 to reciprocate on the slide rail 31. When the slide block 32 and the support column 4 move toward the fixed block 432 and the drive plate 434, the inclined plate of the inclined plate block 431 on the support column 4 hits the drive plate 434. Since the drive plate 434 is limited by the limiting groove 433 of the fixed block 432, the drive plate 434 pushes the inclined plate on the inclined plate block 431, thereby causing the inclined plate block 431 to rotate. The rotating inclined plate block 431... 1. The rotating shaft 421 and the rotating block 422 rotate synchronously, causing the liquid groove 423 on the rotating block 422 to rotate the lubricating oil. When the liquid groove 423 on the rotating block 422 rotates to the bottom, the lubricating oil in the liquid groove 423 drips onto the slide rail 31 through the oil leakage hole connected to the bottom of the mounting groove 41, adding lubricating oil between the slide block 32 and the slide rail 31, preventing the lubricating oil film on the slide rail 31 from being lost and thinned, thereby avoiding friction between the slide block 32 and the slide rail 31 and causing wear that affects the accurate positioning of the slide block 32.

[0054] The volume of the liquid tank 423 on the rotating block 422 is 0.5ml. When the rotating block 422 rotates once, the liquid tank 423 on the rotating block 422 delivers 0.5ml of lubricating oil to prevent excessive lubricating oil from being delivered by the liquid tank 423, which would cause oil to overflow between the slide rail 31 and the slide seat 32.

[0055] Example 2

[0056] Example 2 is a further improvement based on Example 1.

[0057] Unlike Example 1, please refer to Figures 1-8 Two support columns 4 have horizontal grooves 46 on their opposite sidewalls. Electromagnetic blocks 47 are fixedly installed in the horizontal grooves 46. A moving mechanism 45 for intermittently energizing the electromagnetic blocks 47 is provided in the mounting groove 41 above the lubricating oil level. A horizontal groove 51 is provided in the horizontal column 5. The inner wall of the horizontal groove 51 is provided with an insulating coating. The two ends of the horizontal groove 51 are connected to the horizontal grooves 46 on the support columns 4. Permanent magnet blocks 52 are slidably and sealed at both ends of the horizontal groove 51. A reset spring is fixedly connected to the end of the permanent magnet block 52 near the electromagnetic block 47. Spring 53, and the other end of the return spring 53 is fixedly connected to the electromagnetic block 47. Conductor blocks III 54 are embedded in the lower walls of both ends of the horizontal groove 51 near the permanent magnet block 52. Limiting blocks 55 are fixedly installed on the upper wall of the horizontal groove 51 between the two conductor blocks III 54. The limiting blocks 55 are used to limit the permanent magnet block 52. A certain amount of conductive liquid is filled in the horizontal groove 51 between the two permanent magnet blocks 52. Conductor blocks IV 56 are fixedly installed on the upper wall of the horizontal groove 51 between the two limiting blocks 55 near the limiting blocks 55.

[0058] Conductor blocks I 44 are symmetrically embedded in the side wall of the mounting groove 41, above the lubricating oil surface. The moving mechanism 45 includes a connecting column 451, a slider 452, and a conductor block II 453. The connecting column 451 is located in the mounting groove 41 above the lubricating oil surface, and several equally spaced sliders 452 are fixedly sleeved on the connecting column 451. The sliders 452 are slidably and sealed in the mounting groove 41. Conductor blocks II 453 are symmetrically embedded in the side wall of the sliders 452. When the sliders 452 with conductor blocks II 453 move downward, the conductor blocks II 453 on each slider 452 will make electrical contact with conductor blocks I 444. Conductor blocks I 44, II 453, III 54, and IV 56 are insulated from each other. Conductor blocks I 44, II 453, and electromagnetic block 47 are electrically connected. Conductor blocks III 54, IV 56, the conductive fluid, and the control device are electrically connected.

[0059] When the electromagnetic block 47 is energized, the electromagnetic block 47 generates a magnetic force that repels the permanent magnet block 52. The magnetic repulsion generated by the electromagnetic block 47 pushes the permanent magnet block 52 to slide into the horizontal groove 51, causing the permanent magnet block 52 to squeeze the conductive liquid in the horizontal groove 51. The liquid level of the conductive liquid rises, thereby causing the liquid level of the conductive liquid to contact the conductor blocks IV 56 at both ends of the horizontal groove 51.

[0060] During the feeding process, the drive plate 434 pushes the inclined plate block 431 to rotate, causing the inclined plate block 431 to drive the rotating shaft 421 and the rotating block 422 to rotate. This causes the lubricating fluid above the rotating block 422 to gradually decrease. As the lubricating fluid level above the rotating block 422 decreases, the connecting column 451, slider 452, and conductor block II 453 on the lubricating fluid surface gradually descend. During the descent, every certain period of time, the conductor block II 453 on the side wall of the slider 452 will contact the conductor block I 44. At this time, the electromagnetic block 47 is energized, and the electromagnetic block 47 generates a magnetic force that repels the permanent magnet block 52. The magnetic repulsion force pushes the permanent magnet block 52 to slide into the horizontal groove 51 until the permanent magnet block 52 slides to the limit block 55. The permanent magnet block 52 squeezes the conductive fluid in the horizontal groove 51, causing the conductive fluid level to rise. When both ends of the horizontal column 5 are tightly fixed by bolts, the horizontal column 5... When column 5 is not tilted, the rising liquid level in the horizontal tank 51 electrically connects the conductor blocks IV 56 at both ends. When the vacuum suction cup 6 vibrates each time it adsorbs raw material, the vacuum suction cup 6 drives the horizontal column 5 to vibrate synchronously, causing the bolts at both ends of the horizontal column 5 to loosen. As a result, when the horizontal column 5 tilts to a certain extent, the rising liquid level in the horizontal tank 51 cannot simultaneously contact the conductor blocks IV 56 at both ends, causing the control device to display an alarm. That is, when the liquid level in the horizontal tank 51 is squeezed by the permanent magnet block 52, the liquid level rises, and the two conductor blocks IV 56 conduct electricity, the control device does not alarm. When the two conductor blocks IV 56 do not conduct electricity simultaneously, the control device alarms. The alarm indicates that the horizontal column 5 is tilted, thus reminding the staff to adjust the horizontal column 5 to prevent it from tilting and affecting the vacuum suction cup 6's adsorption and positioning of the raw material.

[0061] A counterweight 454 is fixedly connected to the top of the connecting column 451, and the bottom end of the counterweight 454 is slidably sealed and installed in the mounting groove 41. The gravity of the counterweight 454 pushes the connecting column 451 and the slider 452 down, ensuring that the connecting column 451 and the slider 452 can always follow the liquid surface of the lubricating oil down. The slider 452 is slidably sealed and installed in the mounting groove 41. The slider 452 at the bottom of the connecting column 451 is in close contact with the liquid surface of the lubricating oil (by controlling the material of the bottom slider 452, the density of the material is less than that of the lubricating oil, ensuring that the slider 452 at this point can always float on the liquid surface).

[0062] Please see Figures 1-8An exhaust valve 57 and a replenishing valve 58 are embedded in the horizontal column 5 above the horizontal groove 51. The exhaust valve 57 and the replenishing valve 58 are connected to the horizontal groove 51. The top of the exhaust valve 57 is connected to a connecting pipe 91. The other end of the connecting pipe 91 is movably connected to the top of the inner wall of the housing 1. The end of the connecting pipe 91 connected to the inner wall of the housing 1 is fixedly connected to a nozzle 92. The jet direction of the nozzle 92 is towards the lens of the industrial camera 9. The conductor block II 453 on the slider 452 is in contact with the conductor block I 44. The electromagnetic block 47 generates a magnetic field that repels the permanent magnet block 52. During the repulsive force, the permanent magnet block 52 squeezes the conductive liquid in the horizontal tank 51. At the same time, the permanent magnet block 52 also squeezes the gas above the conductive liquid, compressing the gas in the horizontal tank 51. Since the gas in the horizontal tank 51 is above the conductive liquid surface, the compressed gas in the horizontal tank 51 enters the connecting pipe 91 through the exhaust valve 57. The gas in the connecting pipe 91 is sprayed onto the lens of the industrial camera 9 through the nozzle 92, thereby cleaning the lens of the industrial camera 9 with air jets to prevent the lens of the industrial camera 9 from having stains that would affect the accurate positioning of the raw materials.

[0063] The exhaust valve 57 and the replenishing valve 58 are one-way valves. The flow direction of the exhaust valve 57 is from inside the horizontal groove 51 to the connecting pipe 91. When the gas in the horizontal groove 51 is squeezed, the gas can be discharged through the exhaust valve 57. The flow direction of the replenishing valve 58 is from the outside to inside the horizontal groove 51. When the electromagnetic block 47 is no longer energized, the reset spring 53 pulls the permanent magnet block 52 to reset, and the outside gas can enter the horizontal groove 51 through the replenishing valve 58 to replenish the gas in the horizontal groove 51.

[0064] This embodiment proposes a visually guided LCD module loading machine, the specific working principle of which is as follows:

[0065] S1. When using the visual guidance LCD module feeder, the slide block 32 drives the support column 4 and the cross column 5 to move back and forth on the slide rail 31.

[0066] S2. When the slide block 32 and the support column 4 move toward the fixed block 432 and the drive plate 434, the inclined plate of the inclined plate block 431 on the support column 4 strikes the drive plate 434, causing the drive plate 434 to push the inclined plate block 431, the rotating shaft 421 and the rotating block 422 to rotate. The liquid groove 423 on the rotating block 422 drives the lubricating oil to rotate. When the liquid groove 423 on the rotating block 422 rotates to the bottom, the lubricating oil in the liquid groove 423 drips onto the slide rail 31 through the oil leakage hole connected to the bottom of the mounting groove 41.

[0067] S3. The lubricating fluid above the rotating block 422 gradually decreases, and the connecting column 451, slider 452 and conductor block II 453 on the surface of the lubricating fluid gradually descend. During the descent, conductor block II 453 on the side wall of slider 452 comes into contact with conductor block I 44. Electromagnetic block 47 is energized to generate a magnetic force that repels permanent magnet block 52. Permanent magnet block 52 squeezes the conductive fluid in horizontal groove 51, causing the liquid level of conductive fluid to rise.

[0068] S4. When the horizontal column 5 is not tilted, the conductive liquid rising in the horizontal tank 51 makes the conductor blocks Ⅳ56 at both ends electrically connected. When the horizontal column 5 is tilted to a certain extent, the conductive liquid rising in the horizontal tank 51 cannot contact the conductor blocks Ⅳ56 at both ends at the same time, thereby causing the control device to display an alarm, indicating that the horizontal column 5 is tilted, and reminding the staff to adjust the horizontal column 5.

[0069] S5. When the permanent magnet 52 squeezes the conductive liquid in the horizontal tank 51, the permanent magnet 52 will also squeeze the gas above the conductive liquid, so that the gas in the horizontal tank 51 is compressed. The gas enters the connecting pipe 91 through the exhaust valve 57. The gas in the connecting pipe 91 is sprayed onto the lens of the industrial camera 9 through the nozzle 92, thereby cleaning the lens of the industrial camera 9 by air jet.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

6. A method of using a visually guided liquid crystal display module feeding machine as described in claim 5, characterized in that: Includes the following steps: S1. When the slide block (32) and support column (4) move toward the fixed block (432) and drive plate (434), the inclined plate of the inclined plate block (431) on the support column (4) hits the drive plate (434), causing the drive plate (434) to push the inclined plate block (431), the rotating shaft (421) and the rotating block (422) to rotate. The liquid groove (423) on the rotating block (422) drives the lubricating oil to rotate. When the liquid groove (423) on the rotating block (422) rotates to the bottom, the lubricating oil in the liquid groove (423) drips onto the slide rail (31) through the oil leakage hole connected to the bottom of the mounting groove (41). S2. The lubricant above the rotating block (422) gradually decreases, and the connecting column (451), slider (452) and conductor block II (453) on the surface of the lubricant gradually descend. During the descent, conductor block II (453) on the side wall of slider (452) intermittently contacts conductor block I (44). Electromagnetic block (47) is energized to generate a magnetic force that repels permanent magnet block (52). Permanent magnet block (52) squeezes the conductive liquid in horizontal groove (51), causing the liquid level of conductive liquid to rise. S3. When the horizontal column (5) does not tilt, the conductive liquid that rises in the horizontal tank (51) makes the conductor blocks IV (56) at both ends electrically connected. When the horizontal column (5) tilts, the conductive liquid that rises in the horizontal tank (51) cannot simultaneously contact the conductor blocks IV (56) at both ends, thus causing the control device to display an alarm, indicating that the horizontal column (5) has tilted. S4. When the permanent magnet block (52) squeezes the conductive liquid in the horizontal tank (51), the permanent magnet block (52) will also squeeze the gas above the conductive liquid, so that the gas in the horizontal tank (51) is compressed. The gas enters the connecting pipe (91) through the exhaust valve (57). The gas in the connecting pipe (91) is sprayed onto the lens of the industrial camera (9) through the nozzle (92), thereby cleaning the lens of the industrial camera (9) by jet cleaning.
