Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a film height detection and feeding mechanism. Background Art

[0002] In the production process of existing remote controls, a tray arranging device is used to place semi-finished remote controls on the conveyor line into a material box for centralized transportation to the next process. In this process, in order to protect the remote controls between two layers, after a single layer of remote controls in the material box is filled, an EPE film needs to be laid to separate the remote controls in different layers.

[0003] However, the existing film feeding method is that an operator first places a film at the bottom of the glue box, then arranges a layer of plastic parts on the tray, and then covers another layer of film, and so on until the entire glue box is filled. This method has low production efficiency and requires personnel to work beside the line, thus increasing the production cost. In addition, since workers cannot leave the line for too long, this method is also prone to the problem of material stacking and line stoppage.

[0004] Therefore, in order to reduce the production cost and avoid the problem of material stacking and line stoppage, we propose a film height detection and feeding mechanism. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages such as low production efficiency in the existing manual operation method, and to propose a film height detection and feeding mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a film height detection and feeding mechanism, which is installed above a double-layer conveyor line and includes a frame, a detection unit and a transfer unit installed on the frame;

[0008] Among them, the transfer unit includes a moving frame sliding on the frame, a driving component is fixedly installed at the front end of the moving frame, and a suction cup component is slidably connected. The driving component is used to drive the suction cup component to move up and down. Above the frame, a displacement component is also provided for driving the moving frame to move linearly.

[0009] Further, the detection unit includes a bracket fixedly installed on the frame, and a sensor is fixedly installed on the bracket.

[0010] Further, the detection unit also includes a cylinder fixed to the side of the frame. A pressing plate is fixedly installed at the shaft end of the cylinder, and a guide rod passing through the cylinder seat is fixed to the upper end of the pressing plate.

[0011] Further, the moving frame includes a horizontal frame slidably disposed above the frame, a vertical frame vertically fixed on the horizontal frame, and a diagonal brace fixed between the horizontal frame and the vertical frame. Among them, the driving assembly is disposed on the front side of the vertical frame.

[0012] Further, the driving assembly includes a base fixed on the moving frame, and an electric push rod fixedly installed on the base. Among them, the suction cup assembly is connected to the shaft end of the electric push rod.

[0013] Further, the suction cup assembly includes a mounting bracket fixed to the shaft end of the electric push rod, and a plurality of suction cup units fixedly installed on the lower side of the mounting bracket. Among them, a guide rod passing through the base is fixed above the mounting bracket.

[0014] Further, the suction cup unit includes a connecting bracket fixed on the mounting bracket, a nut seat fixedly installed on the connecting bracket, a hollow tube passing through the inner side of the nut seat, and a spring fixedly connected between the hollow tube and the nut seat. Among them, one end of the hollow tube is connected to a suction cup and the other end is connected to a joint.

[0015] A film height detection and feeding mechanism proposed by the present utility model has the beneficial effects that: in the present utility model, the adopted detection unit is used to detect the number of films in the material frame to be entered into the working station at the rear side. When the single layer of the remote control in the material frame at the working station is fully filled, the transfer unit grabs the film of the middle material frame and transfers and places it inside the material frame at the working station to realize automatic feeding of the film, without manual laying. This design can not only effectively improve the efficiency of the remote control tray loading operation, but also reduce the amount of manual input during the tray loading operation.

[0023] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-6 For an embodiment of the present invention, it discloses a film height detection and feeding mechanism. Specifically, this structure is installed above the double-layer conveyor line 1 and is used to detect and transfer and place the film inside the material box. The device includes a frame 2 and a detection unit 3 and a transfer unit 4 installed on the frame 2;

[0025] Among them, the transfer unit 4 includes a moving frame 41 that slides on the frame 2. At the front end of the moving frame 41, a driving assembly 42 is fixedly installed and a suction cup assembly 43 is slidably connected. The driving assembly 42 is used to drive the suction cup assembly 43 to move up and down. Above the frame 2, a displacement assembly 44 for driving the moving frame 41 to move linearly is also provided. As a preference, in this embodiment, the displacement assembly 44 is set as a ball screw assembly. The moving frame 41 is connected to the moving seat of the ball screw assembly to achieve linear movement. This means is a conventional means for those skilled in the art and will not be elaborated here.

[0026] In some embodiments, the detection unit 3 in the present invention includes a support 31 fixedly installed on the frame 2. A sensor 32 is fixedly installed on the support 31. The sensor 32 is preferably set as a laser distance sensor, which is used to detect the thickness of the film in the rear material box. Of course, the sensor 32 should be connected to an external control unit to obtain the number of films in the current material box according to the thickness of a single film.

[0027] It should be noted that before the film in the material box is loaded onto the double-layer conveyor line 1, it can be uniformly placed manually.

[0028] Based on the above embodiments, in order to position the rear material box to improve the stability and accuracy of detection, in this embodiment, the detection unit 3 further includes a cylinder 33 fixed to the side of the frame 2. A pressing plate 34 is fixedly installed at the shaft end of the cylinder 33, and a guide rod 35 passing through the cylinder block of the cylinder 33 is fixed to the upper end of the pressing plate 34.

[0029] Specifically, during detection, the front material box enters the tail end above the double-layer conveyor line 1. At this time, a robotic arm places the remote control. Then, the cylinder 33 drives the pressing plate 34 to extend, and the pressing plate 34 presses against the inner side of the rear material box. It should be noted that three material boxes are placed above the double-layer conveyor line 1. The front material box is carried and driven to move up and down by the lifting mechanism 6. After placement, it moves downward and is removed outward from the lower side of the double-layer conveyor line 1. The middle material box is used for the material supply of the film by the transfer unit 4. After each layer of the front material box is filled with remote controls, the transfer unit 4 adsorbs a film and lays it above the layer of laid remote controls. The pressing plate 34 corresponds to the rear material box and is used to detect the number of films.

[0030] It should be noted that in this embodiment, the moving frame 41 includes a horizontal frame 411 sliding above the frame 2. A vertical frame 412 is vertically fixed on the horizontal frame 411, and a diagonal support frame 413 is also fixed between the horizontal frame 411 and the vertical frame 412. Among them, the driving component 42 is arranged on the front side of the vertical frame 412. That is, in this embodiment, the entire moving frame 41 adopts a triangular frame structure design, which can improve the installation stability of the front driving component 42.

[0031] Furthermore, in this embodiment, the driving component 42 includes a base 421 fixed on the moving frame 41. An electric push rod 422 is fixedly installed on the base 421, and the upper end of the electric push rod 422 is fixed to the vertical frame 412. Among them, the suction cup component 43 is connected to the shaft end of the electric push rod 422.

[0032] In some embodiments, the suction cup component 43 in the present utility model includes a mounting frame fixed to the shaft end of the electric push rod 422. A plurality of suction cup units 5 are fixedly installed on the lower side of the mounting frame. A guide rod 431 passing through the base 421 is fixed above the mounting frame. The guide rod 431 is used to guide the movement of the mounting frame. Preferably, two guide rods 431 are provided in this embodiment.

[0033] Based on the above embodiments, in this embodiment, the suction cup unit 5 includes a connecting frame 51 fixed to the mounting frame. A nut seat 52 is fixedly installed on the connecting frame 51. A hollow tube 53 is inserted through the inner side of the nut seat 52. A spring 54 is fixedly connected between the hollow tube 53 and the nut seat 52. One end of the hollow tube 53 is connected to a suction cup 55, and the other end is connected to a joint 56. Through the movable plug-in design of the hollow tube 53 and the cooperation of the spring 54, the movement adaptation when contacting the film can be realized to ensure that multiple suction cups 55 can all contact and adsorb the film. Of course, the joint 56 is used to externally connect a vacuum device to achieve the effect of vacuum adsorption.

[0034] During operation, the robotic arm sequentially grabs the remote controls on the conveyor line. Two bins are placed above the double-layer conveyor line 1, and one bin is conveyed to the lifting mechanism 6. The robotic arm places the grabbed remote controls into the front bin. When the single-layer remote controls in the front bin are full, the transfer unit 4 moves to grab the film in the middle bin. After grabbing, it is transferred and placed in the front bin. The detection unit 3 detects the number of films in the rear bin to ensure the repetition times of the transfer of the subsequent transfer unit 4. When the front bin is full, the lifting mechanism 6 drives it to move down and is removed from the lower side of the double-layer conveyor line 1. At the same time, the double-layer conveyor line 1 continues to supply one bin to the lifting mechanism 6 above, and at the same time, another bin enters above the double-layer conveyor line 1. In this way, when the bin is used for arranging the remote controls on the tray, continuous automatic detection and arrangement of the number of films are realized, effectively improving the tray arranging efficiency.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
