DETAILED DESCRIPTION

[0044] 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.

[0045] See also Figure 1-7 The present invention provides a technical solution: a precision component foam application device based on machine vision, including a frame 1, and also including:

[0046] A foam feed port 2 is provided on the frame 1;

[0047] A transport module 3, disposed on the frame 1, for transporting precision components from one side of the frame 1 to the other side;

[0048] The application module is arranged in the frame 1, and is used for receiving the foam from the foam feed port 2, and conveying the foam to the transport module 3 for application.

[0049] The transport module 3 includes two sets of conveyor belts symmetrically arranged on the frame 1, which are used to mount and transport precision components.

[0050] Preferably, the application module comprises:

[0051] The rotating material taking component 4 is arranged in the frame 1, and is used to take the material from the foam feeding port 2 and rotate it to the transport module 3;

[0052] The pressing assembly 5 is arranged in the frame 1, and is used to rotate the material taking assembly 4 to the transport module 3, and press the foam thereon onto the precision assembly;

[0053] The calibration component 6 is arranged at the transport module 3 and is used to calibrate and fix the position of the precision components on the transport module 3 when the pressing component 5 is pressed downward.

[0054] In addition, the rotating material taking component 4 comprises:

[0055] A rotating frame 41 is mounted in the frame 1, and a rotating motor 42 is installed on the rotating frame 41;

[0056] A rotating plate 43 is mounted on the rotating end of the rotating motor 42, and a plurality of groups of material taking plates 44 are mounted on the rotating plate 43 in a circular array;

[0057] A plurality of groups of mounting grooves 45 are arranged through the feeding plate 44. A negative pressure device 46 is arranged on the feeding plate 44 at the plurality of groups of the mounting grooves 45 for performing negative pressure adsorption on the foam placed at the mounting grooves 45. The negative pressure device 46 is arranged to slide relative to the feeding plate 44 through an elastic member 47. The elastic member 47 can be arranged as an elastic telescopic rod.

[0058] At the same time, the pressing assembly 5 includes:

[0059] The pressing frame 51 is set up in the frame 1 at the transport module 3;

[0060] A first telescopic cylinder 52 is installed on the pressing frame 51. A pressing plate 53 is provided at the telescopic end of the first telescopic cylinder 52. A pressing rod 54 is provided on the pressing plate 53 for pressing down the negative pressure device 46. The pressing plate 53 is arranged in the plurality of the taking plates 44.

[0061] During the application operation, the foam is placed in the installation groove 45 of the material taking plate 44 from the foam feeding port 2, and is adsorbed by the negative pressure device 46. Then the rotating motor 42 rotates to drive the material taking plate 44 to rotate. When the material taking plate 44 rotates to the vertical direction of the transport module 3, it stops rotating. The rotating motor 42 rotates 360 degrees each time divided by the number of groups set for taking the material. Then the first telescopic cylinder 52 presses down to drive the pressing plate 53 to move down, so as to contact the negative pressure device 46. When the downward pressure continues, , which will drive the foam adsorbed by the negative pressure device 46 to move downward and away from the installation groove 45, toward the precision component until it is attached to the precision component. Then the negative pressure device 46 ends the negative pressure adsorption and resets. At the same time, the negative pressure device 46 is synchronously reset under the action of the elastic member 47 to complete one application operation. At the same time, during this application process, the foam installation operation in the installation groove 45 on another set of material collection plates 44 can be carried out synchronously, thereby achieving reasonable use of time, saving the overall application operation time, and realizing simultaneous application and loading.

[0062] In addition, an imager is provided on one side of the pressing plate 53 close to the transport module 3 for sensing the precision components transported by the transport module 3. That is, when the precision components are presented on the imager, the transport unit can be controlled to stop transporting, so that the precision components stay at the application position to wait for the application operation, so as to realize the preliminary regulation of the application position of the precision components by the machine vision of the equipment.

[0063] Meanwhile, the calibration component 6 comprises:

[0064] A transverse positioning member 61 in the transport direction of the transport module 3 is arranged in the frame 1 and is used for further positioning and fixing the foam after the transport module 3 transports it to the application position;

[0065] The vertical fixing member 62 in the vertical direction of the transport direction of the transport module 3 is arranged in the frame 1, and is used for the transport module 3 to transport the foam to the application position and then cooperate with the horizontal positioning member 61 for auxiliary fixation to prevent the position displacement of the precision components during the application and pressing process, resulting in inaccurate application position.

[0066] Wherein, the transverse positioning member 61 comprises:

[0067] A slider 611 symmetrically arranged at the application position, wherein the slider 611 is slidably arranged in the frame 1;

[0068] A second telescopic cylinder 612 is disposed on the slider 611, and a calibration block 613 for lateral calibration of the precision component is disposed at the telescopic end of the second telescopic cylinder 612;

[0069] The first rack 614 is disposed on the side of the pressing plate 53 and extends downward to the position of the slider 611;

[0070] A second rack 615 is provided on the side of the slider 611. A first gear 616 is provided at the intersection of the first rack 614 and the second rack 615. The first gear 616 is meshed with the first rack 614 and the second rack 615.

[0071] A synchronous moving part, disposed between the two groups of sliders 611, for realizing synchronous movement of the two groups of sliders 611;

[0072] In actual use, the calibration block 613 can be set as an elastic block. When the precision component is calibrated and the pressing component 5 is pressed and applied, the calibration position has a small deformation amount, so that when the pressing plate 53 moves down for pressing, the foam absorbed by the negative pressure device 46 just touches the precision part, and the two calibration blocks 613 are both in contact with the precision part. When the pressure is continued to be pressed down and the application is completed, the displacement distance is very small, so that the pressing is achieved by the pressure matching the glue on the foam application surface. At this time, the calibration block 613 is set as an elastic block to avoid damage to the precision component during calibration;

[0073] In the motion state, when the pressing plate 53 is pressed down, the first gear 616 is driven to rotate by the first rack 614, thereby driving the second rack 615 to move, thereby driving the slider 611 to approach one side of the precision component. At the same time, during the approaching process, the second telescopic cylinder 612 will rise to the height of the precision component. This rising process can be completed in advance to avoid motion interference when the precision component is unloaded to the other side through the transport module 3 after the application is completed;

[0074] It should be noted that, in actual setting, in order to mesh with the first rack 614 and the second rack 615, the thickness of the first gear 616 should be set slightly thicker, so as to achieve meshing with the first rack 614 and the second rack 615 on the plane, and the first gear 616 can rotate at a fixed point at this position through the gear shaft.

[0075] In addition, the synchronous moving unit includes:

[0076] Two sets of third racks 617 are obliquely symmetrically arranged at the lower ends of the two sets of sliders 611;

[0077] The second gear 618 is rotatably disposed on the frame 1 and is meshed with the two sets of the third racks 617 , and the rotation point is the oblique symmetric center point of the two sets of the third racks 617 .

[0078] Finally, the vertical fixing member 62 includes a third telescopic cylinder 621 disposed on both sides of the transport module 3, and a fixing plate 622 is disposed at the telescopic end of the third telescopic cylinder 621;

[0079] The vertical fixation is completed synchronously when the horizontal calibration is completed.
