Description

Technical Field

[0001] The utility model relates to the technical field of fuse end cap installation, and specifically, to an automatic installation mechanism for fuse end caps. Background Art

[0002] In the traditional fuse end cap installation scheme, first, the end caps are manually transferred from a disposable tray to a common plastic tray with slightly harder material, and then the plastic trays are stacked in sequence. Since the operation speed of manual work is sometimes fast and sometimes slow, the transfer mechanism often jams during operation, resulting in inaccurate and intermittent tray detection signals, which makes the subsequent end cap suction mechanism prone to crashing into the machine, consuming working hours and being prone to errors. Moreover, due to the large gaps between the stacked plastic trays, it is easy to cause unstable material taking. Secondly, the degree of automation in the end cap installation process is insufficient. Usually, manual operation or semi-automatic equipment is used, which limits the improvement of production efficiency. If manual installation is adopted, there will be a phenomenon of tilted caps, and at the same time, it is difficult to ensure the tightness, affecting the product performance. While using semi-automatic equipment is prone to tube body breakage due to improper operation or inaccurate equipment adjustment, increasing 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 due to the end cap not being properly aligned during the installation process, increasing the rejection rate. Summary of the Utility Model

[0003] Aiming at the defects in the prior art, the purpose of the utility model is to provide an automatic installation mechanism for fuse end caps. By setting a two-time positioning structure for the end caps, accurate positioning of the end cap installation can be achieved, ensuring the accuracy of the installation angle and position of the end caps. At the same time, automated production is adopted to improve production efficiency and product qualification rate.

[0004] To solve the above technical problems, the utility model provides an automatic installation mechanism for fuse end caps, including an end cap feeding module, a primary end cap positioning tray, an end cap installation module, a tube body transmission module, and a servo controller. The end cap feeding module, the primary end cap positioning tray, the end cap installation module, and the tube body transmission module are all electrically connected to the servo controller;

[0005] The tube body transmission module is arranged on one side of the end cap installation module and is used to provide tube bodies for the end cap installation module;

[0006] The end cap feeding module and the primary end cap positioning tray are arranged on the other side of the end cap installation module. The end cap feeding module is arranged on one side of the primary end cap positioning tray and is used to provide unpositioned end caps for the primary end cap positioning tray. The upper end surface of the primary end cap positioning tray is provided with a primary end cap positioning structure matching the end cap and is used to perform primary positioning on the end cap;

[0007] The end cap mounting module includes a moving sub-module and a secondary positioning sub-module. The moving sub-module is located on one side of the secondary positioning sub-module. The secondary positioning sub-module includes an end cap secondary positioning structure, a pipe body positioning base, and a clamping and flipping structure. The moving sub-module is used to move the pipe body located in the pipe body transmission module into the pipe body positioning base to position the pipe body before end cap installation, and to move the end cap located on the primary positioning tray of the end cap to the end cap secondary positioning structure for secondary positioning of the end cap, and then move the secondary-positioned end cap to the pipe body, and realize the automatic installation of the end cap through the clamping and flipping structure.

[0008] Among them, the moving sub-module includes a moving device and a vision detection structure. The moving device and the vision detection structure are detachably connected. The vision detection structure is electrically connected to an image analysis system, and is used to take pictures of the end cap feeding module, the primary positioning tray of the end cap, the pipe body transmission module, and the secondary positioning sub-module, so as to determine the coordinates and terminal slot angles of the un-positioned end cap and the coordinates of the positioned end cap and pipe body through the image analysis system, and then enable the moving device to accurately move the end cap and the pipe body under the control of the servo controller, and is used to take pictures of the pipe body after the end cap is installed to analyze whether the installation effect meets the preset conditions and record the installation information for easy traceability.

[0009] Further, the secondary positioning sub-module further includes a third bracket. The lower end surfaces of the end cap secondary positioning structure, the pipe body positioning base, and the clamping and flipping structure are all detachably connected to the upper end surface of the third bracket.

[0015] Furthermore, the end cap sucking structure includes a suction head part, a vacuum negative pressure device and an end cap rotating mechanism. The suction head part is connected to the vacuum negative pressure device. Under the negative pressure action of the vacuum negative pressure device, the suction head part generates suction force to realize the sucking of the end cap. Moreover, the suction head part is also axially connected to the end cap rotating mechanism. The rotation of the end cap rotating mechanism drives the end cap sucked by the suction head part to rotate, thereby realizing the adjustment of the end cap angle, so that the secondary positioning terminal is inserted into the terminal slot of the end cap.

[0016] Furthermore, the tube body clamping structure includes a clamping cylinder and a first clamping jaw, and the clamping cylinder is connected to the first clamping jaw.

[0017] Furthermore, the secondary positioning sub-module further includes a clamping and flipping structure. The clamping and flipping structure is located on one side of the tube body positioning base. The lower end surface of the clamping and flipping structure is detachably connected to the upper end surface of the third telescopic structure.

The clamping and flipping structure includes a clamping and flipping cylinder and a second clamping jaw, and the clamping and flipping cylinder is connected to the second clamping jaw;

[0018] When the end cap is sleeved on the tube body, the second clamping jaw provides a downward pressure on the end cap to realize the fixation between the end cap and the tube body;

[0019] When the end cap is installed on one side of the tube body and not installed on the other side, when the third telescopic structure is in the first position, the second clamping jaw of the clamping and flipping structure clamps the outer wall of the tube body, so that the third telescopic structure changes from the first position to the second position. When the third telescopic structure is in the second position, under the flipping action of the clamping and flipping structure, the tube body flips, so that after the tube body flips, the third telescopic structure changes from the second position to the first position, thereby completing the installation of the end cap on the other side of the tube body.

When the second telescopic structure is in the third position, one end of the lower end surface of the pressing block contacts the terminal of the tube body.

[0021] Further, a plurality of the first-stage end cap positioning structures are regularly distributed on the upper end surface of the first-stage end cap positioning tray. The first-stage end cap positioning structure includes a first-stage positioning terminal that matches the terminal of the tube body.

[0022] Further, the moving sub-module further includes a lighting device. The lighting device is located below the vision detection structure and is detachably connected to the connecting frame to provide a light source for the vision detection structure.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] 1. By providing the two-stage positioning structure for the end cap, accurate positioning of the end cap installation can be achieved, ensuring the accuracy of the installation angle and position of the end cap, reducing the rejection rate, and avoiding the situation in the traditional solution where the end cap installation is only calibrated once during installation, which easily damages the terminal coating due to the end cap not being properly aligned.

[0026] 2. Automated production is adopted, which improves production efficiency and avoids the phenomena of tilted caps and difficult-to-guarantee tightness during manual installation, thereby affecting product performance. Moreover, it also avoids the situation where the tube body is easily damaged and the material loss is increased due to improper operation or inaccurate equipment adjustment when using semi-automatic equipment, which is beneficial to further improving the product qualification rate.

[0027] 3. Compared with the traditional technical solution of manually transferring the end cap from a disposable tray to a slightly harder ordinary plastic suction tray and then stacking the plastic suction trays in sequence, this technical solution does not require stacking the first-stage end cap positioning trays in sequence, avoiding unstable material taking. And an automated moving device is used to transfer the end cap from the end cap tray to the first-stage end cap positioning tray, which is convenient to operate, easy to place, has stable efficiency, and avoids the frequent jamming during the operation of the transfer mechanism, resulting in inaccurate tray detection signals that sometimes appear and sometimes disappear, causing the subsequent end cap suction mechanism to easily collide with the machine, consuming working hours and being prone to errors. In addition, a round of visual defect inspection can be carried out through the vision detection structure after the placement is completed. The inspection process is convenient and fast, and the system's defect judgment criteria are constant, avoiding human judgment errors.

[0028] 4. By providing the first-stage end cap positioning structure on the first-stage end cap positioning tray, preliminary end cap positioning can be carried out during the first transfer of the end cap, effectively utilizing the first transfer of the end cap, avoiding the accumulation of positioning errors in one link, and reducing the accident risk after mistakes.

[0029] 5. The secondary positioning for tool change is fast. For end caps of different specifications, only the corresponding secondary positioning structure of the end cap needs to be replaced.

[0030] 6. The positioning accuracy of the end cap suction structure is high. There is no need for cumbersome vision photography in each step. It can be automatically positioned according to the coordinates taught by the servo controller, realizing blind picking and placing.

[0031] 7. By setting up the vision detection structure, the coordinates of each end cap, each tube body, the secondary positioning structure of the end cap, and the tube body positioning base can be accurately obtained. Furthermore, blind picking and placing of the end cap and the tube body as well as automatic installation of the end cap can be realized. At the same time, relevant installation information of the tube body and the end cap can be uploaded, and the traceability is strong. Description of the Drawings

At this time, the teeth of the other tray tooth inserting structure 105 shorten and are withdrawn from the lower end surface of the end cap tray 103 at the corresponding position. The other first telescopic structure 108 continues to extend until the position of the empty end cap tray 103 on the other second end cap tray rack 109 corresponds to the other tray tooth inserting structure 105, then the teeth of the other tray tooth inserting structure 105 extend so that the upper end surface of the teeth contacts the lower end surface of the end cap tray 103 at the corresponding position. Then, after the other first telescopic structure 108 shortens to a preset position, the other second end cap tray rack 109 slides to a preset position on the other second slide rail 106 through the other first connecting member 107 and continues the next operation.
