Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically, to an anti-misassembly and anti-missing bushing press-fitting machine. Background Art

[0002] The automobile subframe is used to connect the vehicle body and the suspension. The automobile subframe mainly consists of a metal body (a welded assembly of a steel structure or an aluminum structure) and a bushing structure. The assembly of the subframe metal body and the bushing structure is completed by a press-fitting device. Due to the increasing variety and similarity of current bushings, manual identification is prone to visual fatigue, and there is a great risk of mis-press-fitting or even missing press-fitting, which affects the NVH (Noise, Vibration, Harshness) performance of the whole vehicle. Eventually, there is a risk of customer complaints in the market, which affects the brand image.

[0003] The prior art discloses a rear subframe bushing press-fitting machine. By installing a floating positioning mechanism on a turntable, the turntable drives the floating positioning mechanism to rotate. The rear subframe is placed on the floating positioning mechanism. During operation, bushings are pre-placed, the turntable is rotated, and then bushings are placed again. After all bushings are placed, a press-fitting mechanism is used to press-fit the bushings, which can quickly press-fit the bushings onto the rear subframe and improve the press-fitting efficiency. However, this device cannot identify the shape, color, and material of the bushings, and is prone to mis-press-fitting or missing press-fitting during the press-fitting process. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-misassembly and anti-missing bushing press-fitting machine, which can identify the shape, color, and material of the bushings and solve the problems of mis-press-fitting or missing press-fitting during the press-fitting process.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An anti-misassembly and anti-missing bushing press-fitting machine includes a press-fitting mechanism for press-fitting a bushing into a sleeve, a workbench, a rotating table, and a controller. The rotating table is rotatably arranged on the workbench. The press-fitting mechanism is arranged on one side of the rotating table. A press-fitting station is arranged on the workbench, and the press-fitting mechanism is located at the press-fitting station. The controller is communicatively connected with the press-fitting mechanism. The machine further includes a detection device, and the detection device includes a visual detection device and a color detection device both arranged on the press-fitting mechanism. An identification station is arranged on the workbench. The detection directions of the visual detection device and the color detection device both face the identification station. The controller is communicatively connected with both the visual detection device and the color detection device.

[0007] According to the above technical means, a bushing press-fitting machine provided by the utility model can place the correct bushing on the subframe sleeve before formal work and move it to the recognition station. The visual inspection device takes a correct photo, and the color detection device detects the correct color and inputs it into the controller for subsequent comparison. The controller controls the visual inspection device to start and identify the shape and position of the bushing. Here, the visual inspection device is an existing visual inspection device, which can take black and white photos of the bushing and compare this photo with the initially taken correct photo to identify the shape and position of the bushing. The controller controls the color detection device to start, and the color detection device identifies the color and material of the bushing. Here, the color detection device uses an existing color detection device, which can identify the color of the bushing through the light reception amounts of red, blue, and green and compare it with the initially input correct color to identify the color of the bushing; the material of the bushing is also identified through color. During the above process, if all identifications are correct, the turntable is rotated to move the bushing to the press-fitting station, and the controller controls the press-fitting mechanism to start and press-fit the bushing; if the detection device identifies incorrectly, the controller will control the device to stop running. This press-fitting machine can identify the shape, position, color, and material of the bushing and solve the problems of incorrect or missed press-fitting during the press-fitting process.

[0008] Further, the visual inspection device includes a position adjustment mechanism and a camera. The position adjustment mechanism is arranged on the press-fitting mechanism, and the camera is arranged on the position adjustment mechanism with the shooting direction facing the recognition station; the controller is communicatively connected to the camera. The position adjustment mechanism can adjust the position of the camera to facilitate the focusing of the camera.

[0009] Further, the color detection device includes a mounting frame, a cylinder, a mounting plate, a color sensor, and a first proximity switch. The mounting frame is arranged on the press-fitting mechanism, the cylinder is arranged on the mounting frame, and the mounting plate is connected to the output end of the cylinder; the color sensor and the first proximity switch are both arranged on the mounting plate with the detection directions facing the recognition station; the controller is communicatively connected to the cylinder, the color sensor, and the first proximity switch. The cylinder is initially in a contracted state, keeping the color sensor away from the bushing, which can prevent the part from colliding with the color sensor when rotating. When the first proximity switch detects that the bushing is at the recognition station and the camera has finished shooting, the controller controls the cylinder to start and drive the color sensor to extend. At the same time of extension, the first proximity switch can detect the distance between the color sensor and the bushing, making the bushing within the effective detection range of the color sensor, and start the color sensor to identify the bushing. Letting the visual inspection device identify before the color sensor extends can prevent the color sensor from interfering with the identification of the visual inspection device.

[0010] Furthermore, the detection device further includes a supplementary lighting component, which is arranged on the press-fitting mechanism. The supplementary lighting component illuminates the identification station, and the controller is communicatively connected to the supplementary lighting component. When using the vision detection device and the color detection device to identify the bushing, the supplementary lighting component is controlled by the controller to turn on, illuminating the bushing located at the identification station, so as to avoid a great impact on the detection result due to different brightness of the bushing.

[0011] Furthermore, it further includes an alarm lamp, a first console, and a second console. The first console and the second console are respectively located on both sides of the workbench. The controller is communicatively connected to the alarm lamp, the first console, and the second console. The alarm lamp lights up red when an error is identified and lights up green constantly when it is identified correctly. Whether the bushing is correct can be visually seen through the alarm lamp. By setting the first console and the second console, the safety issue during double-person operation can be ensured.

[0012] Furthermore, multiple groups of opposed switches are arranged on the turntable. The controller is communicatively connected to the multiple groups of opposed switches. The placement position and specification of the subframe can be detected through the opposed switches.

[0013] Furthermore, a rotating mechanism is arranged on the workbench. The rotating mechanism is arranged on the workbench, the turntable is connected to the output end of the rotating mechanism, and the controller is communicatively connected to the rotating mechanism. Starting the rotating mechanism to drive the turntable to rotate can automatically rotate the subframe, saving manpower.

[0014] Furthermore, a supporting component is arranged on the workbench. The supporting component abuts against the turntable. The supporting component always supports the turntable during the rotation of the turntable, enabling the rotation of the turntable to be more stable.

[0015] Furthermore, it further includes an initial position sensing mechanism. The initial position sensing mechanism includes a photoelectric sensor and an initial position detection piece. The photoelectric sensor is arranged on the workbench, the initial position detection piece is arranged on the turntable, the detection direction of the photoelectric sensor faces the initial position detection piece, and the controller is communicatively connected to the photoelectric sensor. The photoelectric sensor can detect the initial position, facilitating the worker to place the subframe and the bushing on the turntable according to the standard position.

[0016] Furthermore, it further includes a process position detection mechanism, which includes a second proximity switch, a press-fitting detection piece, and an identification detection piece. The second proximity switch is arranged on the workbench, and both the press-fitting detection piece and the identification detection piece are arranged on the rotating table. The number of the press-fitting detection pieces and the identification detection pieces is equal to the number of bushings to be press-fitted. The controller is communicatively connected to the second proximity switch. When the second proximity switch detects the press-fitting detection piece, the bushing is located at the press-fitting station. When the second proximity switch detects the identification detection piece, the bushing is located at the identification station. This can ensure that the bushing is located at the press-fitting station or the identification station.

[0017] Compared with the prior art, the beneficial effects are as follows:

[0018] 1. For the anti-misassembly and anti-missing bushing press provided by the present utility model, by setting up a vision detection device to identify the shape and position of the bushing, and by setting up a color detection device to identify the color and material of the bushing, it can solve the problems of mis-press-fitting or missing press-fitting during the press-fitting process.

[0019] 2. For the anti-misassembly and anti-missing bushing press provided by the present utility model, by setting up a first proximity switch, it can automatically control the position of the color sensor, making the color sensor located within the effective detection range during detection, which can avoid the parts from colliding with the color sensor when rotating; at the same time, it can avoid the color sensor from interfering with the identification of the vision detection device.

[0020] 3. For the anti-misassembly and anti-missing bushing press provided by the present utility model, by setting up a rotating mechanism, the rotating table can be automatically rotated. By setting up an initial position sensing mechanism, the rotating table can be located at the same position when initially placing the subframe and the bushing, which is convenient for workers to place the subframe and the bushing on the rotating table according to the standard position.

[0021] 4.

[0034] Embodiment 1

[0035] As Figures 1 to 9 shown, this embodiment provides an anti-misalignment and anti-leakage bushing press-fitting machine, which includes a press-fitting mechanism 1 for press-fitting a bushing onto a casing, a workbench 2, a rotating table 3, and a controller 4. The rotating table 3 is rotatably arranged on the workbench 2, the press-fitting mechanism 1 is arranged on one side of the rotating table 3, a press-fitting station 21 is provided on the workbench 2, the press-fitting mechanism 1 is located at the press-fitting station 21, and the controller 4 is communicatively connected to the press-fitting mechanism 1; it further includes a detection device 5, and the detection device 5 includes a visual detection device 501 and a color detection device 502 both arranged on the press-fitting mechanism 1, and an identification station 22 is provided on the workbench 2; the detection directions of the visual detection device 501 and the color detection device 502 both face the identification station 22; the controller 4 is communicatively connected to both the visual detection device 501 and the color detection device 502.

[0036] According to the above technical means, a bushing press-fitting machine for preventing misoperation and omission provided by the utility model, before formal work, place the correct bushing on the subframe sleeve, move it to the recognition station, the visual inspection device 501 takes a correct photo, and the color detection device 502 detects the correct color and inputs it into the controller 4 for subsequent comparison. The controller 4 controls the visual inspection device 501 to start, and identifies the shape and position of the bushing. Here, the visual inspection device 501 is an existing visual inspection device, which can take black and white photos of the bushing and compare this photo with the correct photo taken initially, so as to identify the shape and position of the bushing; the controller 4 controls the color detection device 502 to start, and the color detection device 502 identifies the color and material of the bushing. Here, the color detection device 502 uses an existing color detection device, which can identify the color of the bushing by the light reception amount of red, blue and green, and compare it with the correct color input initially, so as to identify the color of the bushing; the material of the bushing is also identified by color. In the above process, when the identifications are all correct, rotate the turntable 3 to move the bushing to the press-fitting station 21, and the controller 4 controls the press-fitting mechanism 1 to start to press-fit the bushing; if the detection device 5 identifies incorrectly, the controller 4 will control the device to stop running. This press-fitting machine can identify the shape, position, color and material of the bushing, and solve the problems of mis-press-fitting or missed press-fitting during the press-fitting process.

[0037] Embodiment 2

[0038] A bushing press-fitting machine for preventing misoperation and omission proposed in this embodiment, on the basis of Embodiment 1, in this embodiment, as Figure 3 and Figure 4 shown, the visual inspection device 501 includes a position adjustment mechanism 511 and a camera 512. The position adjustment mechanism 511 is arranged on the press-fitting mechanism 1, and the camera 512 is arranged on the position adjustment mechanism 511, and the shooting direction faces the recognition station; the controller 4 is communicatively connected to the camera 512. The position adjustment mechanism 511 can adjust the position of the camera 512, so as to facilitate the focusing of the camera 512 and make the shooting effect of the camera 512 better.

[0039] The position adjustment mechanism 511 includes a horizontal adjustment rod and a vertical adjustment rod. The horizontal adjustment rod is installed on the press-fitting mechanism 1, and the vertical adjustment rod is horizontally slidably installed on the horizontal adjustment rod through a sliding member, and the vertical adjustment rod is fixed at the required position on the horizontal adjustment rod through a first fastener, so as to be able to adjust the horizontal position of the camera 512; at the same time, the vertical adjustment rod can slide in the vertical direction relative to the sliding member and is fixed at the required position of the sliding member through a second fastener, so as to be able to adjust the vertical position of the camera 512; the camera 512 is installed on the vertical adjustment rod.

[0040] The camera 512 adopts a camera of the prior art. The model of the camera 512 adopted in the present utility model is Hikvision SC6560C, which can take black and white photos of the articles in the shooting direction. The photos taken during the formal operation can be compared with the correct photos taken initially, so as to judge the position of the bushing placed on the subframe and whether the shape of the bushing itself is correct.

[0041] The color detection device 502 includes a mounting frame 521, a cylinder 522, a mounting plate 523, a color sensor 524 and a first proximity switch 525. The mounting frame 521 is arranged on the pressing mechanism 1, the cylinder 522 is arranged on the mounting frame 521, and the mounting plate 523 is connected to the output end of the cylinder 522; both the color sensor 524 and the first proximity switch 525 are arranged on the mounting plate 523, and the detection directions are both towards the identification station 22; the controller 4 is communicatively connected to the cylinder 522, the color sensor 524 and the first proximity switch 525. The color sensor 524 adopts a color sensor of the prior art. The model of the color sensor 524 adopted in the present utility model is LA-W500-2, which can identify the color of the articles in the detection direction according to the light reception amounts of red, blue and green.

[0042] Since the color sensor 524 has an effective detection range, and the closer the detection distance of the color sensor 524 is, the better the detection effect is. Therefore, when the first proximity switch 525 detects that the bushing is at the identification station, the controller 4 controls the cylinder 522 to start and drive the color sensor 524 to extend, so that the color sensor 524 approaches the bushing. At this time, the first proximity switch 525 can detect the distance between the bushing and the color sensor 524, so that the bushing falls into the effective detection range of the color sensor 524, and the color sensor 524 is started to identify the bushing. After the color sensor 524 finishes the identification, the cylinder is started to contract back to the original position, so that the color sensor 524 is far away from the bushing, avoiding the parts from colliding with the color sensor 524 when rotating.

[0043] At the same time, since the addition of the cylinder 522 can control the telescoping of the color sensor 524, when the camera 512 takes a photo of the bushing, the color sensor 524 can also be moved out of the photo-taking range of the camera 512, which can avoid the color sensor 524 from affecting the photo taken by the camera 512 and avoid alarming due to different photos taken for other reasons.

[0044] The detection device 5 further includes a supplementary lighting component 503. The supplementary lighting component 503 is provided on the pressing mechanism 1. The supplementary lighting component 503 illuminates the identification station 22. The controller 4 is communicatively connected to the supplementary lighting component 503. When using the vision detection device 501 and the color detection device 502 to identify the bushing, the controller 4 controls the supplementary lighting component 503 to turn on, illuminating the bushing located at the identification station 22, which can ensure that the bushing is in the same lighting environment each time it is identified, avoiding a great impact on the detection result due to different brightness of the bushing.

The first console 402 and the second console 403 are respectively located on both sides of the workbench 2. The controller 4 is communicatively connected to the alarm lamp 401, the first console 402 and the second console 403.

[0047] The alarm lamp 401 lights up red when an error is recognized and lights up green constantly when it is recognized correctly. Whether the bushing is correct can be visually seen through the alarm lamp 401. Since the subframe is very heavy, two people are required to operate during work. By setting the first console 402 and the second console 403, it can prevent one person from starting while the other person is still working, ensuring the safety issue during double-person operation.

[0059] Embodiment 8
