Description

Technical Field

[0001] This invention relates to the field of automobile assembly technology, and more specifically, to a sunroof / skylight conveyor device for automobile final assembly workshops. Background Technology

[0002] The standby vacuum suction cup lift uses a standby workstation to grab sunroofs and awnings from the aerial transport section of the sunroof and awning conveyor line in the automotive assembly workshop, vertically transports the sunroofs and awnings to the installation height, and finally delivers them to the installation station. Most existing conveying devices use vacuum suction cups to grab sunroofs and awnings. In actual operation, dust may accumulate on the surface of the sunroof and awning. After prolonged operation, dust may remain at the contact points between the suction cup and the sunroof and awning, posing a risk of insecure gripping. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a sunroof and awning conveying device for automobile assembly workshop, which has the advantage of avoiding dust affecting the suction cup's gripping of the sunroof and awning.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sunroof and canopy conveying device for automobile assembly workshop, comprising a column, a gripping component on the right side of the column, a lifting component fixedly installed at the top of the column, and a carriage component slidably connected to the right end of the column;

[0006] A vacuum pump is fixedly installed at the top of the main frame, and the output end of the vacuum pump is fixedly connected to a vacuum suction cup. Status detection components and positioning components are fixedly installed on both the front and rear sides of the main frame.

[0007] As a preferred embodiment of the present invention, the cleaning structure includes a metal plate, which is fixedly installed at the bottom end of a ball screw. A mounting groove is provided at the bottom of the metal plate, and a rubber strip is inserted into the inner cavity of the mounting groove. A plug is inserted into the end of the mounting groove, and a locking pin is inserted into the plug and the left end of the metal plate. A rubber pad is fixedly installed at the bottom end of the metal plate.

[0008] As a preferred embodiment of the present invention, the slide assembly includes a sliding seat, which is slidably connected to the right side of the column. A second motor is fixedly installed on the top of the right end of the sliding seat. A swing arm is fixedly installed on the output end of the second motor. A connecting arm is fixedly installed on the bottom end of the swing arm. A connecting rod is rotatably connected to the bottom end of the sliding seat. A rotating shaft is rotatably connected to the right end of the connecting arm.

[0009] As a preferred embodiment of the present invention, the lifting assembly includes a motor, which is fixedly installed at the top of the column. A roller is fixedly sleeved at the output end of the motor, and a lifting belt is wound around the surface of the roller. An on / off detection switch is fixedly installed on the right side of the top of the column, and a pressure wheel is slidably connected to the right side of the top of the column. A spring is fixedly installed between the middle of the pressure wheel and the column.

[0010] As a preferred embodiment of the present invention, the right end of the clamping wheel is located below the on / off detection switch, the left end of the clamping wheel is in contact with the lifting belt, and the bottom end of the lifting belt is fixed on the sliding seat.

[0011] As a preferred embodiment of the present invention, the status detection component includes a mounting frame, which is fixedly installed at both ends of the main frame. A photoelectric switch is detachably connected to the middle of the mounting frame via a nut, and a reflector is rotatably connected to the top of the ball screw.

[0012] As a preferred embodiment of the present invention, the positioning component includes a positioning rod, which is fixedly installed on the top of a nut. A positioning clamp is fixedly installed on the right end of the reflector. A spring is fixedly installed between the bottom end of the positioning clamp and the nut. A limit frame is fixedly installed on the top of the main frame.

[0013] As a preferred embodiment of the present invention, a detection component is provided at one end of the vacuum suction cup near the center of the main frame. The detection component includes an electromagnet, which is fixedly installed at the bottom end of the nut, and an iron ring is fixedly installed at the bottom end of the ball screw.

[0014] As a preferred embodiment of the present invention, the detection assembly further includes a connecting cylinder, which is fixedly mounted on a vacuum suction cup. A piston is slidably connected to the inner cavity of the connecting cylinder. A fixing rod and a spring are fixedly mounted at the top and bottom of the piston, respectively. The top of the fixing rod is fixedly mounted on an extension rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention, by setting a ball screw, ensures that when the main frame moves downward, the cleaning structure at the bottom of the ball screw first contacts the sunroof. At this time, the ball screw continues to drive the vacuum suction cup downward, while the cleaning structure is obstructed by the sunroof and cannot move further downward, causing the ball screw to move upward within the nut. Due to the meshing between the nut and the ball screw, the ball screw rotates as it moves upward, thereby driving the cleaning structure to rotate on the sunroof and cleaning the area on the sunroof where the vacuum suction cup is about to pick up and grab. This prevents dust from sticking to the vacuum suction cup and causing residue, thus preventing dust from affecting the vacuum suction cup's gripping of the sunroof and sunroof.

[0017] 2. This invention utilizes an electromagnet. After the vacuum suction cup fully adsorbs and grasps the object, the electromagnet is energized and generates magnetism, causing it to exert an upward force on the iron ring. When the vacuum suction cup contacts the skylight canopy, the ball screw moves upward to a position where the iron ring is below the extension rod and in contact with the extension rod. If the vacuum suction cup is stably and completely adsorbed onto the skylight canopy at this point, the connecting cylinder and the vacuum suction cup are under negative pressure, and the magnetic force on the iron ring cannot pull the extension rod upward. However, if the vacuum suction cup is not stably and completely adsorbed onto the skylight canopy, there will be leakage between the skylight canopy and the vacuum suction cup. In this case, the magnetic force on the iron ring will drive the extension rod upward. The operator can determine whether the vacuum suction cup is stably adsorbed onto the skylight canopy by observing whether the extension rod moves upward. Attached Figure Description

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, the present invention provides a sunroof and canopy conveying device for automobile assembly workshop, including a column 1, a gripping component 2 on the right side of the column 1, a lifting component 3 fixedly installed at the top of the column 1, and a carriage component 4 slidably connected to the right end of the column 1.

[0029] The gripping component 2 includes a main frame 21. Vacuum suction cups 23 are movably connected to the front and rear sides of the main frame 21 through hollow universal ball assembly 22. A nut 24 is fixedly installed at the bottom of the main frame 21. A ball screw 25 is engaged in the middle of the nut 24. A cleaning structure 26 is fixedly installed at the bottom of the ball screw 25.

[0030] A vacuum pump 8 is fixedly installed at the top of the main frame 21. The output end of the vacuum pump 8 is fixedly connected to the vacuum suction cup 23. Status detection components 5 and positioning components 7 are fixedly installed on both the front and rear sides of the main frame 21.

[0031] By setting the ball screw 25, when the main frame 21 moves down as a whole, the cleaning structure 26 at the bottom of the ball screw 25 first contacts the sunroof. At this time, the ball screw 25 continues to drive the vacuum suction cup 23 to move down, while the cleaning structure 26 is obstructed by the sunroof and cannot move down further, causing the ball screw 25 to move up inside the nut 24. Due to the meshing between the nut 24 and the ball screw 25, the ball screw 25 rotates as it moves up, thereby driving the cleaning structure 26 to rotate on the sunroof and cleaning the area on the sunroof where the vacuum suction cup 23 is about to pick up and grab. This prevents dust from sticking to the vacuum suction cup 23 and causing residue, thus preventing dust from affecting the vacuum suction cup 23's gripping of the sunroof and the sunroof.

[0032] The cleaning structure 26 includes a metal plate 261, which is fixedly installed at the bottom end of the ball screw 25. The bottom of the metal plate 261 has a mounting groove 262, and a rubber strip 263 is inserted into the inner cavity of the mounting groove 262. A plug 264 is inserted into the end of the mounting groove 262, and a locking pin 265 is inserted into the plug 264 and the left end of the metal plate 261. A rubber pad 266 is fixedly installed at the bottom end of the metal plate 261.

[0033] By providing a detachable rubber strip 263 at the bottom of the metal plate 261, the rotation of the metal plate 261 during normal operation drives the rubber strip 263 to rotate, which scrapes and cleans the dust on the sunroof. The rubber pad 266 prevents the metal plate 261 from directly and rigidly contacting the sunroof, thus avoiding damage to the sunroof. After pulling the locking pin 265 upward, the plug 264 can be removed, and the rubber strip 263 can be replaced. The operation is simple and convenient.

[0034] The carriage assembly 4 includes a sliding seat 41, which is slidably connected to the right side of the column 1. A second motor 42 is fixedly installed on the top of the right end of the sliding seat 41. A swing arm 43 is fixedly installed on the output end of the second motor 42. A connecting arm 44 is fixedly installed on the bottom end of the swing arm 43. A connecting rod 45 is rotatably connected to the bottom end of the sliding seat 41. A rotating shaft 46 is rotatably connected to the right end of the connecting arm 44.

[0035] The sliding seat 41 drives the swing arm 43 to rotate, which in turn drives the connecting arm 44 to rotate, and through the rotating shaft 46 drives the gripping component 2 to shift horizontally. During rotation, the connecting arm 44 rotates due to the connecting rod 45, see [reference needed]. Figure 4 This ensures that the status detection component 5 moves only in the horizontal direction and does not rotate around the central axis, thus guaranteeing that the angle between the grasping component 2 and the skylight canopy does not change.

[0036] The lifting assembly 3 includes a motor 31, which is fixedly installed at the top of the column 1. A roller 32 is fixedly sleeved at the output end of the motor 31. A lifting belt 33 is wound around the surface of the roller 32. An on / off detection switch 36 is fixedly installed on the right side of the top of the column 1. A pressure wheel 34 is slidably connected to the right side of the top of the column 1. A spring 35 is fixedly installed between the middle of the pressure wheel 34 and the column 1.

[0037] The motor 31 drives the drum 32 to rotate. When the drum 32 rotates, the lifting belt 33 can be wound around the drum 32, thereby pulling the sliding seat 41 upward and causing the carriage assembly 4 and the gripping assembly 2 to move upward.

[0038] The right end of the clamping wheel 34 is located below the on / off detection switch 36, the left end of the clamping wheel 34 is in contact with the lifting belt 33, and the bottom end of the lifting belt 33 is fixed on the sliding seat 41.

[0039] In normal condition, the left end of the pressure wheel 34 is pressed against the right side of the lifting belt 33. Since the sliding seat 41 is fixed to the lifting belt 33, the sliding seat 41 applies tension to the lifting belt 33, and the lifting belt 33 is in a taut state. The lifting belt 33 presses the pressure wheel 34 under the on / off detection switch 36, so that the signal of the on / off detection switch 36 is normally closed. When the lifting belt 33 is loose, the pressure applied by the lifting belt 33 to the pressure wheel 34 is insufficient to overcome the elastic force of the spring 35 in the compressed state. At this time, the spring 35 drives the pressure wheel 34 to pop out under the action of the elastic force. At this time, the signal of the on / off detection switch 36 is opened and an alarm is issued.

[0040] The status detection component 5 includes a mounting frame 51, which is fixedly installed at the front and rear ends of the main frame 21. A photoelectric switch 52 is detachably connected to the middle of the mounting frame 51 via a nut, and a reflector 53 is rotatably connected to the top of the ball screw 25.

[0041] As the ball screw 25 rotates and moves upward, it will drive the reflector head 53 to move upward. In the initial state, the reflector head 53 is located below the photoelectric switch 52. When the vacuum suction cup 23 contacts the skylight canopy, the ball screw 25 will transport the reflector head 53 to the front of the photoelectric switch 52. At this time, the photoelectric switch 52 detects the signal and proceeds to the next operation.

[0042] The positioning component 7 includes a positioning rod 71, which is fixedly installed on the top of the nut 24. A positioning clamp 72 is fixedly installed on the right end of the reflector 53. A spring 73 is fixedly installed between the bottom end of the positioning clamp 72 and the nut 24. A limit frame 74 is fixedly installed on the top of the main frame 21.

[0043] By setting the limiting bracket 74, after the sunroof and canopy are installed in place, the gripping component 2 lowers the sunroof and canopy, at which point the two separate. When the ball screw 25 leaves the sunroof and canopy, the limiting bracket 74, which is in a stretched state, will pull down the reflector head 53 under the action of elastic force, thereby driving the photoelectric switch 52 to move down and reset. By setting the positioning rod 71 and the positioning clamp 72, the movement of the reflector head 53 is positioned and guided, ensuring that the reflector head 53 can only move up and down and cannot rotate, so as to ensure that the reflector head 53 can always be aligned with the photoelectric switch 52.

[0044] Among them, the vacuum suction cup 23 is provided with a detection component 6 at one end near the center of the main frame 21. The detection component 6 includes an electromagnet 61, which is fixedly installed at the bottom end of the nut 24. An iron ring 66 is fixedly installed at the bottom end of the ball screw 25.

[0045] By setting up an electromagnet 61, after the vacuum suction cup 23 has completely attracted and grasped the iron ring, the electromagnet 61 is energized and generates magnetism, so that the electromagnet 61 exerts an upward force on the iron ring 66 through magnetic force.

[0046] The detection component 6 also includes a connecting cylinder 62, which is fixedly mounted on the vacuum suction cup 23. A piston 63 is slidably connected to the inner cavity of the connecting cylinder 62. A fixing rod 64 and a spring 67 are fixedly mounted on the top and bottom ends of the piston 63, respectively. The top end of the fixing rod 64 is fixedly mounted on the extension rod 65.

[0047] When the vacuum suction cup 23 contacts the skylight canopy, the ball screw 25 moves upward to the position where the iron ring 66 is below the extension rod 65 and in contact with the extension rod 65. At this time, after the electromagnet 61 is energized, an upward force is applied to the iron ring 66 through the electromagnet 61. If the vacuum suction cup 23 is completely and stably attached to the skylight canopy at this time, the connecting cylinder 62 and the vacuum suction cup 23 are in a negative pressure state, and the magnetic force on the iron ring 66 cannot pull the extension rod 65 upward. However, if the vacuum suction cup 23 is not completely and stably attached to the skylight canopy, there will be leakage between the skylight canopy and the vacuum suction cup 23. At this time, the magnetic force on the iron ring 66 will drive the extension rod 65 upward. The operator can judge whether the vacuum suction cup 23 is stably attached to the skylight canopy by observing whether the extension rod 65 moves upward.

[0048] Working principle and usage process of this invention:

[0049] In use, the operator starts the motor 31 to control the rotation of the roller 32, releasing the lifting belt 33 on the roller 32, causing the carriage assembly 4 and the gripping assembly 2 to slide down toward the skylight canopy. Before the vacuum suction cup 23 contacts the skylight canopy, the cleaning structure 26 at the bottom of the ball screw 25 first contacts the skylight canopy. At this time, the ball screw 25 continues to drive the vacuum suction cup 23 to move down, while the cleaning structure 26 is obstructed by the skylight canopy and cannot move down further, causing the ball screw 25 to move up inside the nut 24. Due to the meshing between the nut 24 and the ball screw 25, the ball screw 25 rotates as it moves up, thereby driving the cleaning structure 26 to rotate on the skylight canopy, scraping and cleaning the area on the skylight canopy where the vacuum suction cup 23 is about to be gripped.

[0050] Then, the vacuum suction cup 23 continues to move downwards driven by the main frame 21. When the vacuum suction cup 23 contacts the skylight canopy, the cleaning structure 26 is offset from the vacuum suction cup 23, and the ball screw 25 moves up to the position where the iron ring 66 is below the extension rod 65, and the iron ring 66 contacts the extension rod 65. At this time, the vacuum pump 8 is started, and the vacuum pump 8 extracts the air from the vacuum suction cup 23, so that the vacuum suction cup 23 and the connecting cylinder 62 are in a vacuum state.

[0051] When the electromagnet 61 is energized, an upward force is applied to the iron ring 66 through the electromagnet 61. If the vacuum suction cup 23 is completely and stably attached to the skylight canopy at this time, the connecting cylinder 62 and the vacuum suction cup 23 are in a negative pressure state, and the magnetic force on the iron ring 66 cannot pull the extension rod 65 upward. However, when the vacuum suction cup 23 is not completely and stably attached to the skylight canopy, there will be leakage between the skylight canopy and the vacuum suction cup 23. At this time, the magnetic force on the iron ring 66 will drive the extension rod 65 upward.

[0052] Then, the motor 31 is started to drive the roller 32 to rotate, which winds the lifting belt 33 onto the roller 32, thereby pulling the sliding seat 41 to slide on the column 1 and raising the sunroof. Then, the motor 42 drives the swing arm 43 to rotate, which in turn drives the connecting arm 44 to rotate, and drives the gripping component 2 to shift horizontally through the rotating shaft 46, moving the sunroof above the installation position. Finally, the sliding seat 41 descends again to place the sunroof on the car roof.
