Description

Technical Field

[0001] The present invention relates to the technical field of relay assembly, and more particularly to an industrial robot for efficiently assembling automotive electronic components. Background Art

[0002] In the field of automotive electronics manufacturing, relays are key electronic components, and their assembly quality directly affects the stability and reliability of the vehicle's electrical system. The existing assembly method for automotive relays is usually to manually press the relay body into the relay housing and then cover it with a relay cover to complete the assembly of the relay.

[0003] However, manually pressing relays can lead to wrist and arm strain after prolonged working hours, resulting in low assembly efficiency. Furthermore, manual relay assembly can be prone to misalignment, causing the relay to shift in position and poor assembly accuracy, thus impacting the quality of relay box production.

[0004] For example, the patent document with announcement number CN11783259B describes an intelligent assembly robot for automotive relays. The robot can adjust the width of the relay housing by clamping and positioning to avoid damage to the pins during transportation. It can also adaptively correct the position of the relay body and the relay cover to avoid problems such as relay installation position offset and poor relay assembly accuracy, effectively improving assembly efficiency.

[0005] However, in the above-mentioned patent document, when the relay housing and the relay body are installed, there is a lack of effective lubrication measures between the relay housing and the body. The relative movement between the two during assembly and subsequent use will generate large friction, aggravating the wear of the contact surface, which not only reduces the reliability of the relay, but also increases the maintenance cost and replacement frequency of the equipment. In addition, in the process of pressing the body into the relay housing, if the pressing force is not properly controlled, it is very easy to cause damage to the relay body. A solution is now provided. Summary of the Invention

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention is to contract the extended end of the cylinder downward to its shortest point, so that the bottom of the inner tube extends to the middle and lower part of the relay housing. When the inner injection port on the inner tube corresponds to the outer injection port on the outer tube, the grease inside the grease box enters the bottom of the inner tube through the oil drain pipe. At this time, the high-pressure wind speed is controlled to enter the inner tube and blow the grease out of the inner tube, flying to the inner wall of the relay housing in the form of circular splashing. After the cylinder is contracted to its shortest point, it is extended upward and reset, so that a small amount of grease remains at the bottom of the inner tube. With the high-pressure wind speed continuously blown out by the blower, the small amount of grease at the bottom of the inner tube is splashed from bottom to top onto the inner wall of the relay housing, completing the grease spraying operation inside the relay housing, avoiding friction and wear caused by relative movement when the relay body and the relay housing are assembled, and improving the smoothness of assembly.

[0019] 2. The present invention is that during the reciprocating motion of the cylinder, the rack is meshed with the gear to realize the action of the movable rod driving the piston plate to reciprocate inside the air box, that is, when the piston plate moves down, the raised rod moves upward, and during the process of the piston plate moving up and resetting, the raised rod is reset. As the top plate continues to reciprocate, the raised rod continues to reciprocate, and in the process of spraying grease onto the inner wall of the relay housing, the relay housing is vibrated slightly in medium and high frequencies, the body is fully vibrated into the relay housing and the installation is completed, without additional thrust being applied to the top of the relay body, thereby avoiding assembly damage to the relay body, and the medium and high frequency vibrations can quickly assemble the relay body and the relay housing, and allow the grease to be more evenly distributed on the contact surface between the relay housing and the relay body, thereby better protecting the contact surface, reducing wear, extending the service life of the relay, and reducing maintenance costs.

[0033] 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.

[0034] Example 1: Please refer to Figures 1-9 As shown, when the relay housing and the relay body are installed, there is a lack of effective lubrication measures between the relay housing and the relay body. The relative movement between the two during assembly and subsequent use will generate large friction, exacerbating the wear of the contact surface. This problem can be solved by the following solution;

[0035] In this embodiment, an industrial robot for efficiently assembling automotive electronic components includes a mounting frame 1 and two sets of belt conveyors 5 symmetrically mounted above the mounting frame. A wear-reducing assembly 4 is disposed above the mounting frame 1 for uniformly spraying wear-reducing grease onto the interior of a relay housing. An optimized fitting assembly 6 is disposed on one side of the wear-reducing assembly 4 for vibration-fitting the relay housing and the relay body.

[0036] It should be noted that a limiting side plate 3 for limiting the position of the relay housing is symmetrically installed above the mounting frame 1. The limiting side plate 3 is connected to the mounting frame 1 through an electric push rod and is used to limit the conveyance of the relay housing.

[0037] The wear reduction assembly 4 includes a fixing plate 41 fixedly connected to the mounting frame 1. An outer tube 43 is vertically mounted on the top wall of the fixing plate 41. A limiting opening 47 is defined on the side wall of the outer tube 43. An inner tube 410 is slidably mounted inside the outer tube 43. A fixing rod 414 is mounted on the bottom wall of the inner tube 410. The bottom end of the fixing rod 414 extends below the inner tube 410 and is fixedly mounted with a convex circular plate 413.

[0038] A pressing plate 48 is slidably provided in the limiting opening 47. One end of the pressing plate 48 is connected to the inner tube 410. A lifting rod 42 is fixedly provided at the other end of the pressing plate 48. The bottom of the lifting rod 42 extends below the fixed plate 41. A cylinder is also fixedly installed on the side wall of the mounting frame 1 and is connected to the bottom of the lifting rod 42.

[0039] An external injection port 412 is defined on the bottom sidewall of the outer tube 43, and an internal injection port 411 is defined on the top sidewall of the inner tube 410. The external injection port 412 and the internal injection port 411 are located on the same straight line. A grease tank 45 is mounted on the top wall of the fixed plate 41, and the output end of the grease tank 45 is connected to the external injection port 412 via an oil drain pipe 46.

[0040] It should be noted that the bottom cross-sectional diameter of the inner tube 410 is smaller than the top cross-sectional diameter. The pressing plate 48 presses the inner tube 410 downward along the stopper 47, and the bottom of the inner tube 410 extends to the lower center of the relay housing. When the inner injection port 411 on the inner tube 410 aligns with the outer injection port 412 on the outer tube 43, the grease in the grease tank 45 flows into the bottom of the inner tube 410 through the oil drain pipe 46.

[0041] A blower 49 is also fixedly mounted on the side wall of the fixed plate 41, and the output end of the blower 49 is connected to the top of the outer tube 43 through the air delivery pipe 44;

[0042] The high-pressure wind enters the inner tube 410 and blows out of the inner tube 410 carrying the grease. The grease is limited by the convex circular plate 413 and flies to the inner wall of the relay housing in the form of circular splashes.

[0043] It should be noted that the belt conveyor 5 is a conveying tool for conveying the relay housing in the prior art, which belongs to the prior art and will not be described in detail here.

[0044] Example 2: Please refer to Figure 1-Figure 2 and Figure 6-Figure 9 As shown in the figure, in the process of pressing the body into the relay housing, if the pressing force is not properly controlled, it is very easy to cause damage to the relay body. The following solution can be used to solve the problem;

[0045] The optimized fitting assembly 6 includes a rack 61 fixedly connected to the bottom side wall of the lifting rod 42, a rear fixing plate 62 is installed on the rear side of the rack 61, and the rear fixing plate 62 is slidably matched with the mounting frame 1. A gear 63 is meshed and connected on the side wall below the rack 61. A connecting shaft 64 is fixedly installed at the center of the gear 63. The connecting shaft 64 is connected to the mounting frame 1 through a fixing plate. An eccentric wheel 65 is fixedly provided on the side wall of the connecting shaft 64 away from the gear 63;

[0046] An air box 68 is fixedly provided on the side wall of the mounting frame 1 below the eccentric wheel 65. A piston plate 69 is slidably provided inside the air box 68. A movable rod 67 is fixedly installed on the top of the piston plate 69. The top of the movable rod 67 extends to the top of the air box 68 and is fixedly connected to a top plate 66. The top plate 66 is in transmission cooperation with the eccentric wheel 65. A thrust spring 1 is sleeved on the outer wall of the movable rod 67 between the top plate 66 and the top wall of the air box 68.

[0047] It should be supplemented here that: when located at the workstation where the relay housing and the relay body are assembled, the relay housing is disposed above the plurality of raised rods 614;

[0048] The rack 61 is meshed with the gear 63, driving the connecting shaft 64 to rotate. The eccentric wheel 65 continuously presses down the top plate 66, and the movable rod 67 drives the piston plate 69 to reciprocate inside the air box 68.

[0049] Two groups of mounting grooves 613 are symmetrically provided above the mounting frame 1, with each group of mounting grooves 613 having four members. Two gas distribution pipes 612 are symmetrically provided inside the mounting frame 1. The two gas distribution pipes 612 are connected by a U-shaped pipe 611, and the output end of the air box 68 is connected to the U-shaped pipe 611 via a boost pipe 610. A second piston plate 615 is slidably provided in the mounting groove 613, and a protruding rod 614 is fixedly provided on the top of the second piston plate 615. The protruding rod 614 and the second piston plate 615 are both slidably matched with the mounting groove 613. A second thrust spring is sleeved on the outer wall of the protruding rod 614 located below the mounting groove 613, and the gas distribution pipe 612 is connected to the mounting groove 613.

[0050] When the piston plate 1 69 moves downward, the gas at the bottom of the air box 68 is squeezed into the U-shaped tube 611 through the booster pipe 610, and then enters the two gas distribution pipes 612 respectively, and then presses the multiple piston plates 2 615 upward, moving the raised rod 614 upward. During the process of the piston plate 1 69 moving upward and returning to its original position, the piston plate 2 615 and the piston plate 1 69 are respectively pushed back to their original position by the thrust spring 2 and the thrust spring 1, and the raised rod 614 is returned to its original position.

[0051] A relay body conveyor 7 and a cover plate conveyor 8 are provided on the outside of the mounting frame 1. A relay body transfer tool 10 for transferring and installing the relay body is provided on the output side of the relay body conveyor 7. A cover plate transfer tool 9 for transferring and installing the cover plate is provided on the output side of the cover plate conveyor 8.

[0052] After the relay body is installed in the relay housing, the cover is installed on the top of the relay housing by the cover transfer tool 9 to complete the assembly of the relay;

[0053] It should be noted that the relay body transfer fixture 10 and the cover plate transfer fixture 9 are prior art devices that have the function of clamping and transferring the relay body and the cover plate, respectively. They are prior art devices and will not be described in detail here. It is sufficient to describe the functions of clamping and transferring the relay body and the cover plate.

[0054] In the present invention, it can be seen from the combination of Example 1 and Example 2 that:

[0055] The wear-reducing component 4 is used to evenly spray wear-reducing grease inside the relay housing, effectively reducing friction and wear during assembly of the relay body and the housing, improving the smoothness of assembly, and optimizing the fitting component 6 to achieve slight medium and high frequency vibration of the raised rod 614 on the relay housing. This process does not require additional thrust to the top of the relay body, avoiding assembly damage caused by improper force application, and the medium and high frequency vibration not only completes the assembly process quickly, but also further promotes the uniform distribution of grease on the contact surface, better protects the contact surface, reduces friction and wear, extends the service life of the relay, and reduces maintenance costs and replacement frequency.

[0056] Working principle:

[0057] Spraying station: The relay housing is intermittently transported by two sets of belt conveyors 5 above the mounting frame 1. When the relay housing is transported to the spraying station: the extended end of the cylinder is retracted downward to its shortest position. During this process, the pressing plate 48 presses the inner tube 410 downward along the limit opening 47, and the bottom of the inner tube 410 extends to the middle and lower part of the relay housing. When the inner injection port 411 on the inner tube 410 corresponds to the outer injection port 412 on the outer tube 43, the grease inside the grease box 45 enters the bottom of the inner tube 410 through the oil drain pipe 46. At this time, the blower 49 is controlled to blow air, and the high-pressure air velocity enters the inner tube 410, carrying the grease out of the inner tube 410. It is limited by the convex circular plate 413 and flies to the inner wall of the relay housing in the form of circular splashes.

[0058] After the cylinder is retracted to its shortest position, it pauses for 1 to 2 seconds and then immediately stretches upward to reset, leaving a small amount of grease at the bottom of the inner tube 410. During this process, the blower 49 continuously blows out high-pressure air, splashing the small amount of grease at the bottom of the inner tube 410 from bottom to top onto the inner wall of the relay housing, completing the grease spraying operation inside the relay housing, avoiding friction and wear caused by relative movement between the relay body and the relay housing during assembly, and improving the smoothness of assembly;

[0059] Assembly station: Located at the station where the relay housing and relay body are assembled. At this point, the relay body has been installed 80% into the relay housing by the relay body transfer tool 10. Under the influence of the reciprocating motion of the cylinder, the rack 61 first moves downward. During this process, the rack 61 engages with the gear 63, driving the connecting shaft 64 to rotate. The eccentric wheel 65 continuously presses down the top plate 66, and the movable rod 67 drives the piston plate 69 to reciprocate inside the air box 68;

[0060] That is, when the piston plate 1 69 moves downward, the gas at the bottom of the air box 68 is squeezed into the U-shaped tube 611 through the booster pipe 610, and then enters the two gas distribution pipes 612 respectively, and then squeezes the multiple piston plates 2 615 upward, so that the raised rod 614 moves upward. In the process of the piston plate 1 69 moving upward and resetting, the piston plate 2 615 and the piston plate 1 69 are respectively pushed back by the thrust spring 2 and the thrust spring 1, and the gas returns to the bottom of the air box 68. As the top plate 66 continuously reciprocates, the raised rod 614 continuously reciprocates. When the cylinder moves upward and resets, the eccentric wheel 65 also continuously presses the top plate 66 downward, so that the raised rod 614 continuously reciprocates.

[0061] Therefore, in the process of spraying grease onto the inner wall of the relay housing, the raised rod 614 continuously reciprocates to complete the slight medium and high frequency vibration of the relay housing, completely vibrating the relay body into the relay housing and completing the installation. There is no need to apply additional thrust to the top of the relay body, avoiding assembly damage to the relay body. The medium and high frequency vibration can quickly complete the assembly of the relay body and the relay housing, and allow the grease to be more evenly distributed on the contact surface between the relay housing and the relay body, better protecting the contact surface, reducing wear caused by friction, helping to extend the service life of the relay and reduce maintenance costs.
