[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 As shown, the present invention provides a technical solution: an automatic gluing machine for a car steering wheel, comprising a steering wheel adjustment unit 1, a leather cover adjustment unit 4, a glue supply unit and a gluing unit, wherein the steering wheel adjustment unit 1 is used to fix the steering wheel and adjust the position of the steering wheel, the leather cover adjustment unit 4 is used to fix the leather cover and adjust the position of the leather cover, the glue supply unit is used to supply glue to the gluing unit through a pipeline, and the gluing unit is used to brush glue on the steering wheel and the leather cover.

[0026] During use, the personnel places the steering wheel on the steering wheel adjustment unit 1 and the leather cover on the leather cover adjustment unit 4. After the steering wheel is fixed by the steering wheel adjustment unit 1, it drives the steering wheel to move so that the steering wheel and the machine workbench table are inclined at an angle of thirty degrees. The glue supply unit supplies glue to the glue coating unit, and the glue coating unit performs glue coating on an area at the rear end of the steering wheel. The glue coating method is that the glue coating unit moves up and down along the rear end area of ​​the steering wheel to brush glue. In the process of moving up and down and brushing glue, the inner circle area and the outer circle area of ​​the steering wheel are also brushed. When the glue coating of an area on the rear end of the steering wheel is completed, the steering wheel adjustment unit 1 adjusts the steering wheel rotation to facilitate the glue coating unit to glue the next area of ​​the steering wheel. The rear end of the steering wheel is divided into four areas. When the glue coating of the four areas is completed, the glue coating unit contacts the steering wheel, and the steering wheel adjustment unit 1 adjusts The steering wheel is rotated, and after the rotation is completed, the gluing unit brushes glue on a circle around the rear end of the steering wheel. The steering wheel adjustment unit 1 adjusts the steering wheel to flip so that the front end of the steering wheel faces the gluing unit. The gluing unit applies glue to an area on the front end of the steering wheel. The gluing method is that the gluing unit moves up and down along the front end area of ​​the steering wheel to apply glue. When the gluing of an area on the front end of the steering wheel is completed, the steering wheel adjustment unit 1 adjusts the steering wheel rotation to facilitate the gluing unit to apply glue to the next area of ​​the steering wheel. The front end of the steering wheel is divided into four areas. When the gluing of the four areas is completed, the gluing unit contacts the steering wheel. The steering wheel adjustment unit 1 adjusts the steering wheel to rotate. After the rotation is completed, the gluing unit brushes glue on a circle around the front end of the steering wheel. Then the steering wheel adjustment unit 1 is reset and unlocked. The steering wheel is in the initial position and the steering wheel is manually removed.

[0027] After the holster adjustment unit 4 fixes the holster, it drives the holster to flip over, and the glue supply unit supplies glue to the glue coating unit. The glue coating unit applies glue to an area of ​​the holster. The holster is divided into four areas. Whenever the gluing of an area is completed, the holster adjustment unit 4 will rotate 45° to facilitate the gluing of the next area of ​​the holster. When the gluing of the four areas is completed, the holster adjustment unit 4 is reset and unlocked, and the steering wheel is manually removed.

[0028] like Figure 2 , 5As shown in Figures 6 and 7, the steering wheel adjustment unit 1 includes a bracket 101, a first motor 102, a second motor 103 and a clamping mechanism. The bracket 101 is fixedly arranged on the machine frame, and the bracket 101 is provided with a first motor 102. The driving end of the first motor 102 is connected to the second motor 103. The driving end of the second motor 103 is provided with a clamping mechanism. The clamping mechanism is used to clamp the steering wheel. The first motor 102 is used to adjust the flipping of the second motor 103 and the clamping mechanism. The second motor 103 is used to adjust the rotation of the clamping mechanism. It includes a rack, a cylinder 404, a steering wheel limiter 105, a clamping portion 104, a protrusion 106 and an adjusting rod 107. The steering wheel limiter 105 and the protrusion 106 are adapted to the holes on the steering wheel, and the steering wheel limiter 105 and the protrusion 106 are arranged at the end of the rack. The cylinder 404 is arranged on one side of the rack. The driving end of the cylinder 404 is rotatably connected to the adjusting rod 107. The clamping portion 104 is rotatably connected to the adjusting rod 107 and the rack respectively. The cylinder 404 is used to adjust the opening and closing of the clamping portion 104 through the adjusting rod 107.

[0029] When in use, the personnel align the center of the steering wheel with the position of the steering wheel protrusion 106, and the limiting mouth of the steering wheel with the steering wheel limiting part 105. After the steering wheel is placed, the cylinder 404 controls the clamping part 104 to close through the regulating rod 107, that is, the clamping part 104 moves to the steering wheel position. The steering wheel is now located between the clamping part 104 and the steering wheel protrusion 106, completing the clamping operation of the steering wheel. Subsequently, the first motor 102 adjusts the second motor 103 and the steering wheel on the clamping mechanism to rotate downward, so that the steering wheel and the machine workbench table are inclined at an angle of thirty degrees, and the gluing unit starts to glue. The steering wheel is in a ring structure, with a view from one side. Angle, the steering wheel is divided into a front half and a rear half from the middle position. During the gluing process, the second motor 103 can be used to adjust the rotation of the steering wheel, so as to cooperate with the gluing unit to apply glue to the rear half of the steering wheel. One circle of the rear half is the four gluing areas of the rear half. After completion, the first motor 102 continues to rotate to adjust the steering wheel as a whole to face the gluing unit, and then continue to gluing. During the gluing process, the second motor 103 can be used to adjust the rotation of the steering wheel, so as to cooperate with the gluing unit to apply glue to the front half of the steering wheel. Then, the first motor 102 drives the steering wheel to reset, and the cylinder 404 controls the clamping part 104 to open through the regulating rod 107, and the personnel take down the product.

[0030] like Figure 1As shown, the glue supply unit includes an electronic scale 3, a peristaltic pump, and a glue barrel. The glue barrel is used to store glue. The electronic scale 3 is used to detect the weight of the glue in the glue barrel. The peristaltic pump is used to transport the glue in the glue barrel to the glue coating unit through a pipeline. The glue coating unit includes an industrial robot 2 and a brush 5 on the industrial robot 2, and the brush 5 is connected to the pipeline.

[0031] During use, the peristaltic pump supplies the glue in the glue barrel to the brush 5 through a pipeline, and the glue is brushed on the steering wheel or leather cover through the cooperation of the industrial robot 2 and the brush 5. The glue weight of an area of ​​the steering wheel or leather cover is preset, and the glue weight can be adjusted accordingly according to the use requirements. When brushing glue on an area, the peristaltic pump supplies a fixed amount of glue to the gluing unit at a uniform speed. The amount of glue applied to an area is calculated according to the glue weight detected by the electronic scale 3, and the difference is obtained by subtracting the weight before starting to supply glue from the current glue weight. When the difference is the same as the preset glue weight, the glue supply is stopped until the gluing unit starts to glue the next area, and the peristaltic pump restarts the glue supply. The glue metering method is to obtain the current glue weight in real time, subtract the current glue weight from the weight when the glue supply was stopped before, and stop the glue supply when the difference is the same as the preset glue weight. In the above method, the glue supply is repeated until the gluing of the steering wheel and the leather cover is completed.

[0032] like Figure 3 , Figure 4 As shown, the leather case adjustment unit 4 includes a support body 401, a third motor 402, a fourth motor 406, a first leather case support portion 403, a cylinder 404, and a second leather case support portion 405. The support body 401 is fixedly arranged on the machine frame, the third motor 402 is arranged on the support body 401, and a fourth motor 406 is arranged on the driving end of the third motor 402. The fourth motor 406 is fixedly connected to the first leather case support portion 403 through a connecting plate, and the cylinder 404 is fixedly arranged on the first leather case support portion 403. The holster first support portion 403 is on the holster, and the driving end of the cylinder 404 is connected to the holster second support portion 405, the cylinder 404 is used to adjust the distance between the holster second support portion 405 and the holster first support portion 403, the holster adjustment unit 4 also includes a plurality of holster limiting portions A01, each of the holster limiting portions A01 is connected to the driving end of the corresponding cylinder 404, and the holster limiting portions A01 are respectively arranged at the end surfaces of the holster first support portion 403 and the holster second support portion 405.

[0033] When in use, the first supporting part 403 of the holster and the second supporting part 405 of the holster form a holster mold, and the holster mold is adapted to the holster. A person puts the holster on the holster mold, and the cylinder 404 adjusts the second supporting part 405 of the holster through the driving end to move it in a direction away from the first supporting part 403 of the holster, and increases the distance between the first supporting part 403 of the holster and the second supporting part 405 of the holster to fix the holster. Then, the cylinder 404 corresponding to each holster limiting part A01 drives the holster limiting part A01 to extend, and the third motor 402 adjusts the holster to flip 180° to shorten the holster. The distance between the holster and the gluing unit makes it convenient to perform the gluing operation. When the holster is flipped over, there is a process of the holster moving upward. The holster limiter A01 extending from the end surface can support the holster to prevent the problem of position displacement during the flipping of the holster. The holster coating is divided into four areas. The fourth motor 406 can adjust the rotation of the holster. Each rotation can cooperate with the gluing unit to glue an area. The gluing unit is used to perform gluing operations on the four areas of the holster four times. After the gluing operation is completed, the holster is reset by the third motor 402, the cylinder 404 is reset, and the holster is manually removed.
