Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] As Figure 1 shown, a preferred embodiment of the present invention provides an automatic detecting device for arc arm brackets. The device mainly includes modules such as the machine platform 1, the vibrating feeding mechanism 2, the waiting material positioning module 3, the rotating and positioning module 5, the transplanting mechanism 4, the side vision detecting mechanism 6, the top vision detecting mechanism 7, and the discharging mechanism 8. Among them, there are two vibrating feeding mechanisms 2 and two waiting material positioning modules 3. The two vibrating feeding mechanisms 2 are respectively docked with the two waiting material positioning modules 3. The two vibrating feeding modules are respectively used for feeding two different types of arc arm brackets. The waiting material positioning module 3 is used for pre-positioning the arc arm brackets so that the transplanting mechanism 4 can grab them and transfer them to the rotating and positioning module 5 for precise positioning. At the same time, the side vision detecting mechanism 6 and the top vision detecting mechanism 7 are used for visual detection of the top and side surfaces of the arc arm brackets. After the detection is completed, discharging is carried out to complete the discharging.

[0030] The vibrating feeding mechanism 2 adopts a conventional vibrating disk assembly and a linear vibrating assembly. The linear vibrating assembly has a linear vibrating track. The vibrating disk assembly conveys the arc arm brackets to the linear vibrating track on the linear vibrating assembly in a vibrating manner. The arc arm brackets will be arranged neatly in a linear arrangement on the linear vibrating track and then conveyed to the waiting material positioning module 3.

[0031] As Figure 2As shown, the material positioning module 3 is composed of a stand 31 and a positioning fixture, wherein the positioning fixture is composed of an upper positioning plate 32, a lower positioning plate 33, a fixing block 34, a lifting cylinder 35, a boss 36 and other components. The stand 31 has a strip hole that passes through the left and right sides. The upper positioning plate 32 is fixed to the side of the stand 31 by bolts, and the height of the upper positioning plate 32 can be adjusted up and down through the strip hole. The lower positioning plate 33 is fixed to the bottom of the upper positioning plate 32 by bolts, and has a slot on the lower positioning plate 33. The boss 36 is located in the slot and can slide up and down along the slot for a certain distance.

[0032] The fixing block 34 is fixed to the bottom of the lower positioning plate 33, and the lifting cylinder 35 is vertically fixed to the side of the fixing block 34. The output end of the lifting cylinder 35 is connected to the bottom of the boss 36, which is used to drive the boss 36 to move up and down. The shape of the boss 36 is similar to the shape of a "convex" character. There is a positioning groove on the upper positioning plate 32, and there is a through hole that passes through the upper and lower parts of the boss 36. The upper part of the boss 36 is inserted into the through hole. The boss 36 is used to carry the arc arm bracket, and the positioning groove is used to roughly position the arc arm bracket.

[0033] There are openings on the front and back sides of the positioning groove, and the width of the opening is roughly the same as the width of the arc arm bracket. The opening close to the side of the vibration feeding mechanism 2 is to facilitate the arc arm bracket to enter the positioning groove. A mounting groove is provided on the side of the upper positioning plate 32 away from the vibration feeding mechanism 2, and a positioning block 37 is installed in the mounting groove. The positioning block 37 is fixed to the lower fixed block 34 by bolts. There is a groove on the side of the positioning block 37, and the shape of the groove is adapted to the shape of the arc arm bracket. The positioning block 37 blocks the opening on the other side of the positioning groove, and at the same time, the groove on the positioning block 37 cooperates with the upper positioning plate 32 and the boss 36 to form a positioning groove. The positioning block 37 can be replaced according to the shape of the product.

[0034] On the upper positioning plate 32, there are avoidance grooves on both sides of the positioning groove, so that the transfer mechanism 4 can grab the arc arm bracket, and the lifting cylinder 35 will lift the boss 36 to a certain height, so that the arc arm bracket is lifted. Then the transfer mechanism 4 will clamp the two sides of the arc arm bracket and transfer it to the rotation positioning module 5.

[0035] The positioning grooves on the two material positioning modules 3 are used to position different types of arc arm brackets. The subsequent mechanisms are shared.

[0036] like Figure 3As shown in the figure, the transplanting mechanism 4 is composed of a three-axis moving module 41 and a clamping module 42. The three-axis moving module 41 has three moving axes to control the up, down, front, back, left, and right movement of the clamping module 42. A discharge plate 10 is arranged on the three-axis moving module 41. The clamping module 42 is slidably connected to the discharge plate 10 up and down. A buffer plate 11 is installed on the inclined material plate. A screw 12 is threadedly connected to the buffer plate 11. The lower end of the screw 12 is connected to the clamping module 42. A buffer spring 13 is sleeved on the screw 12. When the clamping module 42 moves down to clamp the arc arm bracket, the buffer spring 13 can play a buffering role to prevent the clamping module 42 from damaging the positioning and detection fixture 56.

[0037] The clamping module 42 is composed of a cylinder mounting plate and a jaw cylinder. The jaw cylinder has two jaws that can open or close. The jaw cylinder controls the opening and closing of the two jaws to clamp the arc arm bracket located on the feeding positioning module 3.

[0038] As Figure 4 shown in the figure, the rotary positioning module 5 is jointly composed of a motor mounting plate 51, a servo motor 52, a rotary table 53, a slide plate cylinder 54, a fixing plate 55, a positioning and detection fixture 56, etc. The motor mounting plate 51 is fixed on the machine table 1. The servo motor 52 is located inside the machine table 1 and fixed at the bottom of the motor mounting plate 51. The rotary table 53 is fixed on the upper part of the motor mounting plate 51 and is drivingly connected to the output end of the servo motor 52. The top of the rotary table 53 is rotatable. The slide plate cylinder 54 is connected to the rotary table 53 through a connecting block 57. The servo motor 52 can drive the slide plate cylinder 54 on the rotary table 53 to rotate in the horizontal plane.

[0039] The fixing plate 55 is fixed on the slide plate cylinder 54 and connected to the output end of the slide plate cylinder 54. The fixing plate 55 can be driven to move back and forth by the slide plate cylinder 54. There are two positioning and detection fixtures 56, both located above the fixing plate 55. The two positioning and detection fixtures 56 are connected to the fixing plate 55 through connecting pieces. Different-shaped positioning grooves are respectively provided on the two positioning and detection fixtures 56 for precise positioning of the arc arm bracket. At the same time, one side of the positioning groove has an opening, and this opening can expose the side of the arc arm bracket so that the side vision detection mechanism 6 can perform vision detection on the side of the arc arm bracket.

[0040] According to requirements, openings can also be provided on other sides of the positioning groove so that the servo motor 52 can control the rotation of the rotary table 53, thereby driving the positioning and detection fixture 56 to rotate, adjusting the position of the arc arm bracket, and facilitating the side vision detection mechanism 6 to perform vision detection on other sides of the arc arm bracket.

[0041] On the other side of the rotary positioning module 5, a light source assembly 15 is provided. The light source assembly 15 is located opposite to the side vision detection mechanism 6, providing supplementary light for the arc arm bracket so as to highlight the side contour shape of the arc arm bracket, facilitating the side vision detection mechanism 6 to perform vision detection on it.

[0042] The light source assembly 15 is also installed on the fixed plate 55. Since the positioning and detection fixture 56 is made of a transparent material, the light source assembly 15 can provide supplementary light for the bottom of the arc arm bracket, and the light will pass through the positioning and detection fixture 56 to highlight the contour shape of the arc arm bracket, so that the top vision detection mechanism 7 can perform vision detection on the top of the arc arm bracket.

[0043] As Figure 5 、 Figure 6 shown, the general structures of the side vision detection mechanism 6 and the top vision detection mechanism 7 are the same. The side vision detection mechanism 6 is composed of a horizontal movement module 61 and a vision camera 14. The vision camera 14 can move through the horizontal movement module 61 and approach the side of the arc arm bracket. The top vision detection mechanism 7 is composed of a lifting module 71 and a vision camera 14. The vision camera 14 can move up and down through the lifting module 71 and approach the top of the arc arm bracket.

[0044] Since the two positioning and detection fixtures 56 are arranged side by side and are respectively used for positioning different types of arc arm brackets. Therefore, the two positioning and detection fixtures 56 can be driven to move horizontally by the slide plate cylinder 54 to switch the positions of the two positioning and detection fixtures 56, so that the positioning and detection fixture 56 loaded with the arc arm bracket to be detected moves to directly below the top vision detection mechanism 7.

[0045] The vision camera 14 will take pictures of the top and side of the arc arm bracket, and then compare and calculate the pictures with the standard pictures in the system to finally obtain the detection result. The blanking mechanism 8 will transfer the arc arm bracket to the corresponding position according to the detection result.

[0046] Referring to Figure 7 , the structure of the blanking mechanism 8 is similar to that of the transplanting mechanism 4, and is also composed of a three-axis movement module 41 and a clamping module 42. Among them, a discharge plate 10 is provided on the three-axis movement module 41. The clamping module 42 is slidably connected to the discharge plate 10 up and down. A buffer plate 11 is installed on the inclined material plate. A screw 12 is threadedly connected to the buffer plate 11. The lower end of the screw 12 is connected to the clamping module 42. A buffer spring 13 is sleeved on the screw 12. When the clamping module 42 moves down to clamp the arc arm bracket, the buffer spring 13 can play a buffering role to prevent the clamping module 42 from damaging the positioning and detection fixture 56.

[0047] As Figure 1 、 Figure 8As shown in the figure, a collecting frame 16 and a plurality of collecting boxes 9 are placed below the blanking mechanism 8. The collecting frame 16 is provided with a plurality of sliding grooves, and each sliding groove is provided with a collecting box 9 which can slide along the sliding groove. Each collecting box 9 contains different arc arm brackets. The collecting boxes 9 are numbered and the position information is entered into the system. The plurality of collecting boxes 9 are respectively used for storing different types of arc arm brackets and classifying them according to the difference in dimensional error. For example, the error is in the range of 1-2 mm in one collecting box 9 and 3-4 mm in another collecting box 9, and so on for classification. The system screens the arc arm brackets according to the detected results, and the blanking mechanism 8 puts the arc arm brackets into the corresponding collecting boxes 9.

[0048] When a certain collecting box 9 is full, the collecting box 9 can be pulled out from the collecting frame 16 and replaced with a new collecting box 9.

[0049] The above technical solution only reflects the preferred technical solution of the technical solution of the present utility model. Some changes that may be made to some parts by those skilled in the art of the present technology all reflect the principle of the present utility model and are within the protection scope of the present utility model.
