Description

Technical Field

[0001] The present invention relates to the technical field of fuse end cap installation, and in particular to an automatic installation mechanism and method for a fuse end cap. Background Art

[0002] In the traditional fuse end cap installation scheme, the end cap is first manually transferred from a disposable tray to an ordinary blister tray with a slightly harder material, and then the blister trays are stacked in sequence. Since the manual operation speed is sometimes fast and sometimes slow, the transfer mechanism often freezes during operation, making the tray detection signal inaccurate, sometimes absent, and causing the subsequent end cap suction mechanism to easily collide with the machine, which is time-consuming and error-prone. In addition, due to the large gap between the stacked blister trays, it is easy to cause unstable material collection. Secondly, the end cap installation process is not automated enough, and manual operation or semi-automatic equipment is usually used, which limits the improvement of production efficiency. If manual installation is used, there will be a skewed cap phenomenon, and the tightness is difficult to ensure, which affects product performance. If semi-automatic equipment is used, it is easy to cause damage to the tube body due to improper operation or inaccurate equipment adjustment, which increases material loss. In addition, since the end cap installation in the traditional scheme is only calibrated once during installation, it is easy to damage the terminal coating during installation due to the end cap not being guided correctly, increasing the scrap rate.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 2. The use of automated production improves production efficiency and avoids the phenomenon of crooked caps and difficulty in ensuring tightness due to manual installation, which in turn affects product performance. It also avoids the situation where improper operation or inaccurate equipment adjustment when using semi-automatic equipment may cause damage to the pipe body and increase material loss, which is conducive to further improving the product qualification rate.

[0035] 3. Compared with the traditional technical solution of manually transferring the end caps from the disposable tray to the ordinary blister tray with a slightly harder material, and then stacking the blister trays in sequence, this technical solution does not need to stack the end caps one-time positioning tray in sequence, avoiding the unstable material picking situation, and uses an automated mobile device to transfer the end caps from the end cap tray to the end cap one-time positioning tray. It is easy to operate, convenient to place, and efficient, avoiding frequent jams in the operation process of the transfer mechanism, making the tray detection signal inaccurate and sometimes absent, causing the subsequent end cap suction mechanism to easily collide with the machine, consuming time and prone to errors. In addition, after the placement is completed, a round of visual defect inspection can be carried out through the visual detection structure. The inspection process is convenient and quick, and the system determines that the defect judgment standard is constant, avoiding human judgment errors.

[0036] 4. By setting an end cap one-time positioning structure on the end cap one-time positioning tray, the preliminary end cap positioning can be performed at the same time as the first end cap transfer, which effectively utilizes the one-time transfer of the end cap, avoids the accumulation of positioning errors in one link, and reduces the risk of accidents after errors.

[0037] 5. The secondary positioning can be changed quickly. For end caps of different specifications, you only need to replace the corresponding end cap secondary positioning structure.

[0038] 6. The end cap suction structure has high positioning accuracy and does not require tedious visual photography at each step. It can automatically position according to the coordinates taught by the servo controller to achieve blind picking and placing.

[0039] 7. By setting up the visual inspection structure, the coordinates of each end cap, each tube body, the end cap secondary positioning structure and the tube body positioning base can be accurately obtained, thereby realizing the blind removal and placement of the end cap and the tube body and the automatic installation of the end cap. At the same time, the relevant installation information of the tube body and the end cap can also be uploaded, with strong traceability. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] In a specific embodiment, the automatic installation method of the fuse end cap may further include:

[0081] The visual inspection structure 307 takes a picture of the end cap feeding module 1 under the moving action of the mobile device, or other automated mobile devices with a shooting function, to obtain a coordinate image of the unpositioned end cap;

[0082] The coordinate image of the unpositioned end cap is transmitted to the image analysis system for image analysis to determine the coordinates of each unpositioned end cap and the angle of the terminal slot;

[0083] According to the terminal slot angles of each unpositioned end cap, the corresponding rotation angle of the end cap suction structure 305 in the mobile device is analyzed and determined;

[0084] The servo controller controls the end cap suction structure 305 in the moving device according to the coordinates of the unpositioned end cap to move the unpositioned end cap to the end cap primary positioning tray 2;

[0085] The visual inspection structure 307 takes pictures of the end cap primary positioning tray 2, the tube body transmission module 4 and the secondary positioning sub-module respectively under the moving action of the moving device to obtain a coordinate image;

[0086] The coordinate image is transmitted to an image analysis system for image analysis to determine the coordinates of each end cap, each tube body, the end cap secondary positioning structure 310 and the tube body positioning base 311;

[0087] The servo controller controls the end cap suction structure 305 in the moving device according to the coordinates to move the end cap from the end cap primary positioning tray 2 to the end cap secondary positioning structure 310. At this time, if there is still a deviation in the angle of the terminal slot of the end cap, the end cap suction structure 305 will blindly align the end cap within a certain angle and place it in the secondary positioning structure 310, and control the tube body clamping structure 306 in the moving device to move the tube body from the tube body transmission module 4 to the tube body positioning base 311;

[0088] The end cap suction structure 305 in the moving device moves the end cap after secondary positioning from the end cap secondary positioning structure 310 to the tube body located in the tube body positioning base 311 under the control of the servo controller;

[0089] The lower end surface of the pressing block 314 contacts the upper end surface of the terminal of the tube body under the action of the second telescopic structure 313. At the same time, the second clamping claw in the clamping flip structure 312 moves to the upper end surface of the end cap under the action of the third telescopic structure, and presses the end cap downward under the action of the third telescopic structure to complete the fixation of the end cap and the tube body.

[0090] The visual inspection structure 307 captures a first inspection image of the tube body after the end cap is installed, and sends the first inspection image to the image analysis system for image analysis;

[0091] When the image analysis system determines that the first detection image meets the preset conditions, the clamping and flipping structure 312 first clamps the tube body, then rises under the action of the third telescopic structure and flips the tube body, and after flipping, it is lowered under the action of the third telescopic structure so that the tube body is located in the tube body positioning base 311 again; when the image analysis system determines that the first detection image does not meet the preset conditions, an error is reported or the tube body is placed in the waste area through the tube body clamping structure 306;

[0092] The end cap suction structure 305 in the moving device moves the end cap after secondary positioning from the end cap secondary positioning structure 310 to the tube body located in the tube body positioning base 311 under the control of the servo controller;

[0093] The lower end surface of the pressing block 314 contacts the upper end surface of the terminal of the tube body under the action of the second telescopic structure 313. At the same time, the second clamping claw in the clamping flip structure 312 moves to the upper end surface of the end cap under the action of the third telescopic structure, and presses the end cap downward under the action of the third telescopic structure to complete the fixation of the end cap and the tube body.

[0094] The visual inspection structure 307 captures a second inspection image of the tube body after the end cap is installed, and sends the second inspection image to the image analysis system for image analysis;

[0095] When the image analysis system determines that the second detection image meets the preset conditions, the tube body clamping structure 306 in the mobile device moves the tube body to the tube body tray 403 in the tube body transmission module 4 for transmission to the next process; when the image analysis system determines that the second detection image does not meet the preset conditions, an error is reported or the tube body is placed in the waste area through the tube body clamping structure 306.
