Description

Technical Field

[0001] This invention belongs to the field of industrial robots, specifically a Cartesian coordinate robot for use on a production line. Background Technology

[0002] In the automotive parts manufacturing industry, Cartesian robots, with their high precision, high reliability, and flexible programming control capabilities, have become key equipment for improving production efficiency and ensuring product quality. With the booming development of the automotive industry, automotive parts processing technology is constantly innovating, and the requirements for processing precision, efficiency, and automation are becoming increasingly stringent. As a core piece of equipment for achieving precise and efficient processing, the technological development of Cartesian robots profoundly impacts the competitiveness and development prospects of the automotive industry.

[0003] Current Cartesian robots typically use motors to drive a lead screw to rotate, thereby achieving linear movement of the slide. However, when the lead screw drives the slider to make linear movements, wear will occur on the lead screw and slider due to prolonged operation. Existing technology is not convenient for automatically lubricating the lead screw and slider during operation, and periodic manual lubrication is still required. However, manual lubrication is prone to omissions and cannot be maintained in the long term. Moreover, lubricating oil often overflows after loading, which not only causes waste but also overflows onto the outside of the transmission components, easily affecting other parts. Secondly, existing lubricating oil spraying methods can mostly only spray lubricating oil to a certain position on the lead screw. As the slider moves laterally, the slider's movement will push most of the lubricating oil down, making it impossible to concentrate it at the engagement point of the lead screw and slider.

[0004] Therefore, the present invention provides a Cartesian coordinate robot for production lines. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem of wear and tear on the lead screw and slider during linear motion driven by a lead screw due to prolonged operation, current technologies do not automatically lubricate the lead screw and slider during operation, requiring periodic manual lubrication. However, manual lubrication is prone to omissions and cannot be consistently maintained. Furthermore, lubricating oil often overflows after loading, causing waste and potentially affecting other parts by spilling onto the outside of the transmission components. Additionally, existing lubricating oil spraying methods mostly only apply lubricating oil to a specific location on the lead screw; as the slider moves laterally, its movement pushes most of the lubricating oil away, preventing it from concentrating at the lead screw and slider engagement point. Therefore, this invention proposes a Cartesian coordinate robot for production lines.

[0008] Preferably, the linkage unit includes a stop block, which is fixedly installed at the end of the piston rod. The outer wall of the stop block is configured as a symmetrical inclined surface. A first spring is sleeved on the outer wall of the piston rod. One end of the first spring is fixedly connected to the stop block, and the other end of the first spring is fixedly connected to the sleeve.

[0009] Preferably, the inner walls of the first slide, the second slide, and the third slide are symmetrically fixed with two spring plates around the second pipe, and the second pipe is attached to the outer wall of the two spring plates.

[0010] Preferably, a guide plate is fixedly connected to the inner wall of the second pipe, and the guide plate is configured to be arc-shaped.

[0011] Preferably, the drive assembly includes three servo motors, which are respectively fixedly installed on one side of the first slide, the second slide, and the third slide. The output ends of the three servo motors extend into the interior of the first slide, the second slide, and the third slide, respectively. Each output end of the three servo motors is fixedly connected to a lead screw, which is connected to the first slider, the second slider, and the third slider via a lead screw and nut pair. Positioning rods are fixedly connected to the inner walls of the first slide, the second slide, and the third slide, respectively, and the positioning rods are slidably connected to the first slider, the second slider, and the third slider, respectively.

[0012] Preferably, a baffle plate is fixedly connected to the inner wall of the third slide.

[0013] Preferably, an extrusion block is fixedly connected to the outer wall of the third slider, the extrusion block is in contact with the inner wall of the baffle plate, a conical groove is formed inside the extrusion block, the lead screw is located inside the conical groove, and the extrusion block is slidably connected to the positioning rod.

[0014] Preferably, the locking assembly includes a fixing box, which is fixedly installed on one side of the first slider. A movable block is slidably connected to the inner wall of the fixing box. A sliding shaft is fixedly connected to the bottom of the movable block. The bottom of the sliding shaft passes through the fixing box and is fixedly connected to a pull bolt. A second spring is sleeved on the outer wall of the sliding shaft. The top of the second spring is fixedly connected to the movable block, and the bottom of the second spring is fixedly connected to the fixing box. A positioning block is fixedly connected to the top of the movable block. The top of the positioning block passes through the fixing box. An L-shaped frame is fixedly connected to the outer wall of the second rotating shaft.

[0015] Preferably, the clamping assembly includes two side plates, which are symmetrically fixedly installed on the inner wall of the mounting plate. Bolts are threadedly connected to the inner wall of the side plates. A knob is fixedly connected to one end of the bolt, and a clamping block is rotatably connected to the other end of the bolt. A sponge pad is fixedly connected to the outer wall of the clamping block.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a Cartesian coordinate robot for a production line, which controls the lateral movement of a first slider, a second slider, and a third slider via a lead screw. Through the cooperation of the first slider, the second slider, and the third slider with corresponding stops, the stops drive the piston plate to move back and forth in the housing. With the cooperation of two one-way valves, the lubricating oil in the housing is squeezed into the second pipe, and the lubricating oil is sprayed onto the lead screw through the second pipe. When the first slider, the second slider, and the third slider pass by, the engagement point between the lead screw and the first slider, the second slider, and the third slider is lubricated.

[0017] 2. The Cartesian coordinate robot for production line described in this invention partially seals the inner wall of the second pipe by setting a guide plate, thereby increasing the pressure of the lubricating oil when it is sprayed out. This makes it easier for the lubricating oil in the second pipe to be sprayed onto the lead screw without being in contact with the pipe. Furthermore, when the vertically moving third slide is in use, the guide plate's inclined surface guides the lubricating oil sprayed from the second pipe to fall more effectively onto the lead screw.

[0018] 3. The Cartesian coordinate robot for production lines described in this invention, through the setting of a baffle plate, can catch the lubricating oil falling from the lead screw in the third slide, preventing the lubricating oil from naturally falling from the lead screw and overflowing to the outside of the third slide. When the third slide moves to a position close to the baffle plate, the extrusion block enters the baffle plate. Under the extrusion of the extrusion block, the lubricating oil caught in the baffle plate flows upward along the conical groove. The lubricating oil flowing upward along the conical groove enters the engagement point between the lead screw and the third slide, facilitating the re-lubrication of the lead screw and the third slide. This not only improves the accuracy of lubrication but also avoids the waste of lubricating oil.

[0019] 4. The Cartesian coordinate robot for production line described in this invention uses an L-shaped frame and a positioning block to adjust the position of the positioning block within the positioning hole, so that the first slide, the second slide, and the third slide are on the same plane. This reduces the space occupied and greatly saves space and improves space utilization during transportation, transfer, and storage. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2As shown, the present invention provides a technical solution: a Cartesian coordinate robot for a production line, comprising a first slide table 1, a first slider 2 slidably connected to the inner wall of the first slide table 1, a second rotating shaft 27 rotatably connected to the top of the first slider 2, a second slide table 3 fixedly connected to the top of the second rotating shaft 27, a locking assembly provided on the outer wall of the first slider 2, a second slider 4 slidably connected to the inner wall of the second slide table 3, a third slide table 5 fixedly connected to the top of the second slider 4, and a third slider 6 slidably connected to the inner wall of the third slide table 5. Driving assemblies are provided inside the first slide table 1, the second slide table 3, and the third slide table 5. A mounting plate 36 is fixedly connected to one side of the third slider 6, and a clamping assembly is provided inside the mounting plate 36. A cavity 10 is provided inside the first slide table 1, the second slide table 3, and the third slide table 5. An injection port 11 is provided at the bottom of the inner wall of the first slide table 1, the second slide table 3, and the third slide table 5, communicating with the cavity 10. The interior of the platform 5 is equipped with a spraying assembly; the drive assembly includes three servo motors 7, which are fixedly installed on one side of the first slide 1, the second slide 3, and the third slide 5, respectively. The output ends of the three servo motors 7 extend into the interior of the first slide 1, the second slide 3, and the third slide 5, respectively. Each output end of the three servo motors 7 is fixedly connected to a lead screw 8, which is connected to the first slider 2, the second slider 4, and the third slider 6, respectively, via a lead screw nut pair. The inner walls of the first slide 1, the second slide 3, and the third slide 5 are all fixedly connected to positioning rods 9, which are slidably connected to the first slider 2, the second slider 4, and the third slider 6, respectively. The clamping assembly includes two side plates 37, which are symmetrically fixedly installed on the inner wall of the mounting plate 36. Bolts 38 are threadedly connected to the inner wall of the side plates 37. A knob 39 is fixedly connected to one end of the bolt 38, and a clamping block 40 is rotatably connected to the other end of the bolt 38. A sponge pad 41 is fixedly connected to the outer wall of the clamping block 40.

[0024] Through the above technical solution, by manually rotating the two knobs 39, the two bolts 38 are rotated, causing the two bolts 38 to move relative to each other or move apart. This, in turn, causes the two clamping blocks 40 to move relative to each other or move apart, thereby achieving the fixing or loosening of the equipment, facilitating the installation or disassembly of the equipment. The sponge pad 41 prevents damage to the equipment when the clamping blocks 40 are moved relative to each other to fix the equipment, improving safety. By starting the servo motor 7, the lead screw 8 is rotated, causing the first slider 2 to move left and right, thereby causing the second slide 3 to move left and right. The second slider 4 and the third slider 6 can be moved by the other two servo motors 7. The second slider 4 can drive the third slide table 5 to move back and forth, and the third slider 6 can move the equipment in the mounting plate 36 up and down, so that the equipment in the mounting plate 36 can be adjusted in three-dimensional space. Lubricating oil is filled into the cavity 10 through the injection port 11. After the servo motor 7 is started, the lubricating oil in the cavity 10 is sprayed onto the engagement point of the first slider 2, the second slider 4, the third slider 6 and the lead screw 8 through the spraying component, so as to lubricate the engagement point of the first slider 2, the second slider 4, the third slider 6 and the lead screw 8.

[0025] like Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, specifically, the spraying assembly includes three first pipes 12, which are respectively fixedly installed inside the first slide 1, the second slide 3, and the third slide 5. The bottom of the first pipe 12 extends into the cavity 10, and the top of the first pipe 12 is rotatably connected to a first rotating shaft 13. The top of the first rotating shaft 13 is fixedly connected to a second pipe 14, and a connecting hose 15 is fixedly connected between the first pipe 12 and the second pipe 14. A sleeve 16 is fixedly connected to the outer wall of the first pipe 12, and a piston plate 17 is slidably connected to the inner wall of the sleeve 16. A piston rod 18 is fixedly connected to one side of the piston plate 17. The inner wall of the first pipe 12 is centered around the sleeve 16. Two one-way valves 21 are centrally symmetrically arranged, both of which open towards the second pipe 14. A linkage unit is provided at one end of the piston rod 18. The linkage unit includes a stop block 20, which is fixedly installed at the end of the piston rod 18. The outer wall of the stop block 20 is set as a symmetrical inclined surface. A first spring 19 is sleeved on the outer wall of the piston rod 18. One end of the first spring 19 is fixedly connected to the stop block 20, and the other end of the first spring 19 is fixedly connected to the sleeve 16. Two spring plates 22 are fixedly connected symmetrically to the inner walls of the first slide 1, the second slide 3, and the third slide 5 with the second pipe 14 as the center. The second pipe 14 is attached to the outer walls of the two spring plates 22.

[0026] Through the above technical solution, when the servo motor 7 controls the lead screw 8 to rotate and cause the first slider 2 to move laterally, as the first slider 2 moves laterally, when the first slider 2 moves to the stop 20, the first slider 2 presses against the inclined surface of the outer wall of the stop 20. Under the pressure of the first slider 2, the stop 20 moves into the housing 16, driving the piston rod 18 to move into the housing 16, causing the piston plate 17 to move towards the first pipe 12. At this time, the first spring 19 is compressed. When the first slider 2 moves away from the stop 20, under the action of the first spring 19, the stop 20 is reset, driving the piston plate 17 to move away from the first pipe 12. This process is repeated. When the piston plate 17 moves away from the first pipe 12, through the pull of the piston plate 17, in conjunction with the two one-way valves 21, the lubricating oil in the cavity 10 is drawn along the first pipe 12 into the housing 16. When the piston plate 17 moves towards the first pipe 12... The movement, through the compression of the piston plate 17 and the cooperation of two one-way valves 21, forces the lubricating oil in the sleeve 16 into the connecting hose 15, and then into the second pipe 14 along the connecting hose 15. The lubricating oil is then sprayed onto the lead screw 8 through the second pipe 14. When the first slider 2 passes by, it lubricates the engagement point between the lead screw 8 and the first slider 2. As the first slider 2 passes through the second pipe 14, it rotates on the first rotating shaft 13. After the first slider 2 passes, the second pipe 14 is precisely aligned with the lead screw 8 under the action of the spring plate 22. Similarly, when the other two lead screws 8 control the lateral movement of the second slider 4 and the third slider 6, the corresponding second pipes 14 can lubricate the engagement point between the second slider 4 and the third slider 6 and the lead screw 8. This solves the problem of the inconvenience of manually applying lubricating oil periodically. While the right-angle robot is operating, the drive components of the right-angle robot are automatically lubricated.

[0027] like Figure 6 As shown, specifically, a guide plate 23 is fixedly connected to the inner wall of the second pipe 14, and the guide plate 23 is set in an arc shape.

[0028] Through the above technical solution, the inner wall of the second pipe 14 is partially blocked by the guide plate 23, which makes the lubricating oil sprayed out with high pressure, so that the lubricating oil in the second pipe 14 can be sprayed onto the lead screw 8 without being in contact with the pipe. When the vertically moving third slide 5 is in use, the lubricating oil sprayed from the second pipe 14 can fall onto the lead screw 8 better by the guidance of the inclined surface of the guide plate 23.

[0029] like Figure 2 , Figure 3 , Figure 5 , Figure 8As shown, specifically, a baffle plate 24 is fixedly connected to the inner wall of the third slide table 5; an extrusion block 25 is fixedly connected to the outer wall of the third slide block 6. The extrusion block 25 fits against the inner wall of the baffle plate 24. A conical groove 26 is opened inside the extrusion block 25. The lead screw 8 is located inside the conical groove 26. The extrusion block 25 is slidably connected to the positioning rod 9.

[0030] Through the above technical solution, the baffle plate 24 can catch the lubricating oil falling from the lead screw 8 in the third slide table 5, preventing the lubricating oil from overflowing to the outside of the third slide table 5 after falling naturally from the lead screw 8. When the third slide block 6 moves to a position close to the baffle plate 24, the extrusion block 25 enters the baffle plate 24. Under the extrusion of the extrusion block 25, the lubricating oil caught in the baffle plate 24 flows upward along the conical groove 26. The lubricating oil flowing upward along the conical groove 26 enters the engagement point between the lead screw 8 and the third slide block 6, which facilitates the lubrication of the lead screw 8 and the third slide block 6 again. This not only improves the accuracy of lubrication, but also avoids the waste of lubricating oil.

[0031] like Figure 2 , Figure 10 As shown, specifically, the locking assembly includes a fixing box 30, which is fixedly installed on one side of the first slider 2. A moving block 31 is slidably connected to the inner wall of the fixing box 30. A sliding shaft 32 is fixedly connected to the bottom of the moving block 31. The bottom of the sliding shaft 32 passes through the fixing box 30 and is fixedly connected to a pull bolt 33. A second spring 34 is sleeved on the outer wall of the sliding shaft 32. The top of the second spring 34 is fixedly connected to the moving block 31, and the bottom of the second spring 34 is fixedly connected to the fixing box 30. A positioning block 35 is fixedly connected to the top of the moving block 31. The top of the positioning block 35 passes through the fixing box 30. An L-shaped frame 28 is fixedly connected to the outer wall of the second rotating shaft 27. Two positioning holes 29 are symmetrically opened inside the L-shaped frame 28. The positioning block 35 fits against the inner wall of the positioning hole 29.

[0032] Through the above technical solution, by manually pulling the bolt 33, the moving block 31 moves downward, thereby causing the positioning block 35 to move downward and exit the current positioning hole 29. Freed from the constraint of the positioning block 35, the second slide 3 can rotate via the rotational connection of the second rotating shaft 27. After rotating the second slide 3 ninety degrees, the L-shaped frame 28 rotates ninety degrees. Releasing the bolt 33 causes the second spring 34 to rebound, causing the positioning block 35 to move upward and insert into another positioning hole 29, fixing the L-shaped frame 28 and thus fixing the second slide 3. This ensures that the first slide 1, second slide 3, and third slide 5 are on the same plane, thereby reducing space occupation and significantly saving space and improving space utilization during transportation, transfer, and storage.

[0033] In use, manually rotating the two knobs 39 rotates the two bolts 38, causing them to move relative to each other or apart. This, in turn, moves the two clamping blocks 40 relative to each other or apart, thus securing or loosening the equipment for easy installation or disassembly. The sponge pad 41 prevents damage to the equipment during the relative movement of the clamping blocks 40, improving safety. Starting the servo motor 7 rotates the lead screw 8, causing the first slider 2 to move left and right, which in turn moves the second slide 3 left and right. Similarly, the other two servo motors 7 can move the second slider 4 and the third slider 6. The second slider 4 can drive the third slide 5 to move back and forth, and the third slider 6 can move the equipment in the mounting plate 36 up and down, so that the equipment in the mounting plate 36 can be adjusted in three-dimensional space. Lubricating oil is filled into the cavity 10 through the injection port 11. When the servo motor 7 controls the lead screw 8 to rotate and make the first slider 2 move laterally, as the first slider 2 moves laterally, when the first slider 2 moves to the stop 20, the first slider 2 presses against the inclined surface of the outer wall of the stop 20. Under the pressure of the first slider 2, the stop 20 moves into the sleeve 16, driving the piston rod 18 to move into the sleeve 16, and making the piston plate 17 move towards the first pipe 12. At this time, the first spring When spring 19 is compressed, and the first slider 2 moves away from the stop 20, the stop 20 is reset by the action of spring 19, causing piston plate 17 to move away from the first pipe 12. This process repeats. When piston plate 17 moves away from the first pipe 12, the pulling action of piston plate 17, in conjunction with the two one-way valves 21, draws the lubricating oil in cavity 10 along the first pipe 12 into sleeve 16. When piston plate 17 moves towards the first pipe 12, the squeezing action of piston plate 17, in conjunction with the two one-way valves 21, squeezes the lubricating oil in sleeve 16 into connecting hose 15, and then along connecting hose 15 into second pipe 14. The lubricating oil is then transported through second pipe 14... Lubricating oil is sprayed onto the lead screw 8. When the first slider 2 passes by, it lubricates the engagement point between the lead screw 8 and the first slider 2. As the first slider 2 passes the second pipe 14, it causes the second pipe 14 to rotate on the first rotating shaft 13. After the first slider 2 passes, under the action of the spring plate 22, the second pipe 14 is precisely aligned with the lead screw 8. Similarly, when the other two lead screws 8 control the lateral movement of the second slider 4 and the third slider 6, the corresponding second pipes 14 can lubricate the engagement points between the second slider 4 and the third slider 6 and the lead screw 8. This solves the problem of the inconvenience of manually applying lubricating oil periodically. The drive components of the right-angle robot are automatically lubricated while the robot is operating.The guide plate 23 partially seals the inner wall of the second pipe 14, resulting in high pressure when the lubricating oil is sprayed out. This facilitates the spraying of lubricating oil from the second pipe 14 onto the lead screw 8 even without contact. Furthermore, when the vertically moving third slide 5 is in use, the inclined surface of the guide plate 23 guides the lubricating oil sprayed from the second pipe 14 to better land on the lead screw 8. The baffle plate 24 catches the lubricating oil falling from the lead screw 8 within the third slide 5, preventing it from overflowing onto the outside of the third slide 5 after naturally falling from the lead screw 8. When the third slide block 6 moves to a position close to the baffle plate 24, the extrusion block 25 enters the baffle plate 24. Under the pressure of the extrusion block 25, the lubricating oil caught in the baffle plate 24 flows upward along the conical groove 26. The lubricating oil flowing upward along the conical groove 26 enters the lead screw 8 and the third slide block 5. The engagement point of slider 6 facilitates re-lubrication of the lead screw 8 and the third slider 6, improving lubrication accuracy. Manually pulling the bolt 33 moves the moving block 31 downwards, causing the positioning block 35 to move downwards, disengaging from the current positioning hole 29. Freed from the constraint of the positioning block 35, the second slide 3 can rotate via the rotational connection of the second rotating shaft 27. Rotating the second slide 3 90 degrees causes the L-shaped frame 28 to rotate 90 degrees. Releasing the bolt 33 causes the second spring 34 to return, moving the positioning block 35 upwards and inserting it into another positioning hole 29, fixing the L-shaped frame 28 and thus fixing the second slide 3. This ensures that the first slide 1, second slide 3, and third slide 5 are on the same plane, reducing space occupation and significantly saving space during transportation, transfer, and storage, thus improving space utilization.
