Description

Technical Field

[0001] This invention relates to the field of fuse end cap installation technology, specifically to an automatic fuse end cap installation mechanism and method. Background Technology

[0002] In traditional fuse end cap installation methods, the end caps are first manually transferred from disposable trays to slightly harder ordinary blister trays, which are then stacked sequentially. Because the manual operation speed varies, the transfer mechanism frequently jams, resulting in inaccurate and intermittent tray detection signals. This causes the subsequent end cap picking mechanism to collide, wasting time and increasing the risk of errors. Furthermore, the large gaps between the stacked blister trays lead to unstable material handling. Secondly, the end cap installation process lacks automation, typically relying on manual operation or semi-automatic equipment, limiting production efficiency. Manual installation can result in misaligned caps and inconsistent tightness, affecting product performance. Semi-automatic equipment is prone to damage due to improper operation or inaccurate adjustments, increasing material waste. Additionally, because traditional methods only perform calibration once during installation, improper alignment of the end caps can damage the terminal coating, increasing the scrap rate. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an automatic installation mechanism and method for fuse end caps. By setting a two-stage positioning structure for the end cap, accurate positioning of the end cap installation can be achieved, ensuring the precision of the installation angle and position of the end cap. At the same time, the use of automated production improves production efficiency and product qualification rate.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] According to a first aspect of the embodiments of this application, an automatic fuse end cap installation mechanism is provided, including an end cap primary positioning tray, an end cap installation module, a tube body transmission module, and a servo controller, wherein the end cap primary positioning tray, the end cap installation module, and the tube body transmission module are all electrically connected to the servo controller;

[0006] The tube body transmission module is disposed on one side of the end cap mounting module and is used to provide the tube body to the end cap mounting module.

[0007] The end cap primary positioning tray is disposed on the other side of the end cap mounting module. The upper surface of the end cap primary positioning tray is provided with an end cap primary positioning structure that matches the end cap, for primary positioning of the end cap.

[0008] The end cap installation 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 tube positioning base, and a clamping and flipping structure. The moving sub-module is used to move the tube located in the tube transfer module to the tube positioning base to achieve positioning of the tube before end cap installation, and to move the end cap located on the end cap primary positioning tray to the end cap secondary positioning structure for secondary positioning of the end cap, and to move the end cap after secondary positioning onto the tube through the clamping and flipping structure to achieve automatic installation of the end cap.

[0009] The mobile sub-module includes a mobile device and a vision detection structure, which 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 primary positioning tray, the tube body transfer module, and the secondary positioning sub-module. The image analysis system determines the coordinates of the end cap and the tube body, enabling the mobile device to move the end cap and the tube body precisely under the control of the servo controller. The system also takes pictures of the tube body after the end cap is installed to analyze whether the installation effect meets the preset conditions and records the installation information for easy traceability.

[0010] In one exemplary embodiment, the secondary positioning sub-module further includes a third bracket, and the lower end faces of the end cap secondary positioning structure, the tube positioning base, and the clamping flipping structure are all detachably connected to the upper end face of the third bracket.

[0011] The secondary positioning structure of the end cap includes a secondary positioning support and a secondary positioning platform. The upper end face of the secondary positioning support is fixedly connected to or integrally formed with the lower end face of the secondary positioning platform. The lower end face of the secondary positioning support is detachably connected to the upper end face of the third bracket. The outer wall of the secondary positioning platform matches the inner wall of the end cap, and the upper end face of the secondary positioning platform is provided with a secondary positioning terminal that matches the terminal of the tube body.

[0012] The upper end face of the tube positioning base is provided with a tube groove that matches the tube body, which is used to accommodate the tube body so as to facilitate the automatic installation of the end cap.

[0013] In one exemplary embodiment, the mobile device includes a three-way moving structure, a connecting frame, an end cap suction structure, and a tube clamping structure. The end cap suction structure, the tube clamping structure, and the vision detection structure are detachably connected to the three-way moving structure through the connecting frame.

[0014] The end cap suction structure is used to move the end cap by suction.

[0015] The tube clamping structure is used to move the tube by clamping.

[0016] In one exemplary embodiment, the end cap suction structure includes a suction head, a vacuum negative pressure device, and an end cap rotation mechanism. The suction head is connected to the vacuum negative pressure device. Under the negative pressure of the vacuum negative pressure device, the suction head generates suction to suction the end cap. Furthermore, the suction head is axially connected to the end cap rotation mechanism. The rotation of the end cap rotation mechanism drives the end cap sucked by the suction head to rotate, thereby adjusting the angle of the end cap and allowing the secondary positioning terminal to be inserted into the terminal slot of the end cap.

[0017] In one exemplary embodiment, the tube clamping structure includes a clamping cylinder and a first gripper, wherein the clamping cylinder is connected to the first gripper.

[0018] In one exemplary embodiment, the secondary positioning sub-module further includes a clamping and flipping structure located on one side of the tube positioning base. The lower end face of the clamping and flipping structure is detachably connected to the upper end face of the third telescopic structure, and the lower end face of the third telescopic structure is detachably connected to the upper end face of the third bracket. The clamping and flipping structure includes a clamping and flipping cylinder and a second gripper, and the clamping and flipping cylinder is connected to the second gripper.

[0019] When the end cap is fitted into the tube body, the second gripper provides downward pressure to the end cap, thereby fixing the end cap to the tube body;

[0020] When the end cap is installed on one side of the tube and not on the other side, when the third telescopic structure is in the first position, the second jaw of the clamping and flipping structure clamps the outer wall of the tube, 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, the tube flips under the flipping action of the clamping and flipping structure, so that after the tube 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.

[0021] In one exemplary embodiment, the secondary positioning sub-module further includes a second telescopic structure and a pressure block. The upper end face of the second telescopic structure is detachably connected to the lower end face of the pressure block, and the lower end face is detachably connected to the upper end face of the third bracket. When the second telescopic structure is in the third position, one end of the lower end face of the pressure block contacts the terminal of the tube body.

[0022] In one exemplary embodiment, the upper surface of the end cap primary positioning tray is regularly distributed with a plurality of end cap primary positioning structures, each end cap primary positioning structure including a primary positioning terminal that matches the terminal of the tube body.

[0023] In one exemplary embodiment, an end cap feeding module is also included, which is electrically connected to the servo controller and is used to provide the end cap to the end cap positioning tray under the control of the servo controller.

[0024] According to a second aspect of the embodiments of this application, an automatic fuse end cap installation method is provided, applied to the automatic fuse end cap installation mechanism described in any one of the above claims, comprising:

[0025] The visual detection structure takes pictures of the end cap primary positioning tray, the tube body transmission module, and the secondary positioning sub-module under the movement of the mobile device, and obtains coordinate images.

[0026] The coordinate image is transmitted to the image analysis system for image analysis to determine the coordinates of each end cap, each tube body, the secondary positioning structure of the end cap, and the positioning base of the tube body;

[0027] The servo controller controls the moving device to move the end cap from the end cap primary positioning tray to the end cap secondary positioning structure according to the coordinates, and moves the tube body from the tube body transfer module to the tube body positioning base;

[0028] Under the control of the servo controller, the mobile device moves the end cap, which has been positioned twice, from the end cap secondary positioning structure to the tube body located inside the tube body positioning base.

[0029] The clamping and flipping structure presses down on the end cap to fix the end cap and the tube body;

[0030] The visual inspection structure captures a first inspection image of the tube body after the end cap has been installed, and sends the first inspection image to the image analysis system for image analysis.

[0031] When the image analysis system determines that the first detected image meets the preset conditions, the clamping and flipping structure flips the tube so that the end cap can be installed on the other side of the tube.

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

[0033] 1. By setting a two-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 scrap rate, and avoiding the situation in traditional solutions where the end cap installation is only calibrated once during installation, which can easily lead to damage to the terminal coating due to the end cap not being aligned.

[0034] 2. The adoption of automated production improves production efficiency and avoids the problems of crooked caps and difficulty in ensuring tightness that occur when using manual installation, which can affect product performance. Furthermore, it avoids the situation where improper operation or inaccurate equipment adjustment can easily lead to pipe damage and increased material waste when using semi-automatic equipment, which is conducive to further improving the product qualification rate.

[0035] 3. Compared to the traditional method of manually transferring end caps from disposable trays to slightly stiffer ordinary blister trays, and then stacking the blister trays sequentially, this method eliminates the need for sequential stacking of end cap positioning trays, avoiding unstable material handling. Furthermore, it utilizes automated mobile equipment to transfer end caps from the end cap trays to the primary positioning trays, making operation convenient, placement easy, and efficiency stable. This avoids frequent jamming during the transfer mechanism, which can lead to inaccurate or intermittent tray detection signals, causing collisions in subsequent end cap picking mechanisms, wasting time, and increasing the risk of errors. In addition, a visual inspection structure can be used for a round of defect checks after placement. The inspection process is convenient and quick, and the system's defect judgment standards are consistent, avoiding human error.

[0036] 4. By setting an end cap primary positioning structure on the end cap primary positioning tray, the initial end cap positioning can be performed at the same time as the first end cap transfer, effectively utilizing the first transfer of the end cap, avoiding the accumulation of positioning errors in one stage, and reducing the risk of accidents after errors.

[0037] 5. Quick secondary positioning and replacement: For end caps of different specifications, simply replace the corresponding secondary positioning structure of the end cap.

[0038] 6. The end cap suction structure has high positioning accuracy, eliminating the need for tedious visual photography at each step. It can automatically position itself based on the coordinates taught by the servo controller, enabling blind picking and placing.

[0039] 7. By setting up a visual inspection structure, the coordinates of each end cap, each tube body, the secondary positioning structure of the end cap, and the positioning base of the tube body can be accurately obtained, thereby realizing blind picking and placing of end caps and tube bodies, as well as automatic installation of end caps. At the same time, the relevant installation information of tube bodies and end caps can be uploaded, which has strong traceability. Attached Figure Description

[0055] The end cap primary positioning tray 2 is set on the other side of the end cap mounting module 3. The upper surface of the end cap primary positioning tray 2 is provided with an end cap primary positioning structure 201 that matches the end cap, which is used to perform primary positioning of the end cap.

[0056] The end cap installation module 3 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 310, a tube positioning base 311, and a clamping and flipping structure 312. The moving sub-module is used to move the tube located in the tube transfer module 4 to the tube positioning base 311 to achieve tube positioning before end cap installation, and to move the end cap located on the end cap primary positioning tray 2 to the end cap secondary positioning structure 310 for secondary positioning of the end cap, and to move the end cap after secondary positioning to the tube and achieve automatic installation of the end cap through the clamping and flipping structure 312.

[0057] The mobile sub-module includes a mobile device and a vision inspection structure 307, which are detachably connected. The vision inspection structure 307 is electrically connected to an image analysis system and is used to take pictures of the end cap primary positioning tray 2, the pipe body transfer module 4, and the secondary positioning sub-module. The image analysis system determines the coordinates of the end cap and the pipe body, enabling the mobile device to move the end cap and the pipe body precisely under the control of the servo controller. It is also 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.

[0058] In one specific embodiment, the automatic fuse end cap installation mechanism further includes an end cap feeding module 1, which is electrically connected to a servo controller and is used to provide end caps to the end cap positioning tray 2 under the control of the servo controller.

[0059] The end cap feeding module 1 includes a first support 101. A first end cap tray frame 102 is mounted on the upper surface of the first support 101. The first end cap tray frame 102 consists of four vertically arranged tray supports. The horizontal cross-section of the space formed by the four tray supports matches that of the end cap trays 103. Multiple end cap trays 103 are vertically stacked inside the first end cap tray frame 102. Two first slide rails 104 are also parallel to each other on the upper surface of the first support 101. The two first slide rails 104 are located on opposite sides of the first end cap tray frame 102. 4. A set of tray insert tooth structures 105 are slidably connected to the upper part; two second slide rails 106 are arranged parallel below the first bracket 101, and a first connector 107 is slidably connected to each second slide rail 106. A first telescopic structure 108 is detachably connected to the upper end face of the first connector 107, and a second end cap tray frame 109 is detachably connected to the upper end face of the first telescopic structure 108. The upper end face of the second end cap tray frame 109 is used to place the end cap tray 103; when the second end cap tray frame 109 is located directly below the first end cap tray frame 102, the first telescopic structure 108 extends... The length is increased so that the upper end face of the second end cap tray 109 contacts the lower end face of the end cap tray 103 located at the bottom of the first end cap tray 102. At this time, the teeth of the tray inserting tooth structure 105 shorten, and the teeth are pulled out from the lower end face of the end cap tray 103 at the corresponding position. The first telescopic structure 108 shortens until the position of the end cap tray 103 located at the second to last layer of the first end cap tray 102 corresponds to the position of the tray inserting tooth structure 105. Then the teeth of the tray inserting tooth structure 105 extend so that the upper end face of the teeth contacts the lower end face of the end cap tray 103 at the corresponding position. After contact, the first telescopic structure 108 continues to shorten to a preset position, and then slides to a preset position on the second slide rail 106 via the first connector 107. The end cap in the end cap tray 103 is then moved to the end cap primary positioning tray 2 by a moving device or other automated moving device. The tray tooth structure 105 slides on the first slide rail 104 under the driving action of a motor or other driving device, and the first connector 107 also slides on the second slide rail 106 under the driving action of a motor or other driving device. The first telescopic structure 108 can be an electric telescopic rod.

[0060] The upper surface of the end cap primary positioning tray 2 is regularly distributed with multiple end cap primary positioning structures 201. Each end cap primary positioning structure 201 includes a primary positioning terminal that matches the terminal of the tube body. Optionally, the end cap primary positioning tray 2 can be provided with end cap primary positioning structures 201 of different specifications on both sides, so that different specifications of end caps can be adapted by flipping the tray, thereby reducing the number of tooling and lowering costs.

[0061] The secondary positioning sub-module also includes a third bracket 309. The lower end faces of the end cap secondary positioning structure 310, the tube positioning base 311, and the clamping and flipping structure 312 are all detachably connected to the upper end face of the third bracket 309. The end cap secondary positioning structure 310 includes a secondary positioning support and a secondary positioning platform. The upper end face of the secondary positioning support is fixedly connected to or integrally formed with the lower end face of the secondary positioning platform. The lower end face of the secondary positioning support is detachably connected to the upper end face of the third bracket 309. The outer wall of the secondary positioning platform matches the inner wall of the end cap, and the upper end face of the secondary positioning platform is provided with a secondary positioning terminal that matches the terminal of the tube. The upper end face of the tube positioning base 311 is provided with a tube groove that matches the tube to accommodate the tube, so as to facilitate the automatic installation of the end cap.

[0062] The mobile sub-module also includes an illumination device 308, which is located below the vision inspection structure 307 and is detachably connected to the connecting frame 304 to provide a light source for the vision inspection structure 307; wherein, the vision inspection structure 307 may employ a high-definition camera;

[0063] The moving device includes a second support 301, a three-way moving structure, a connecting frame 304, an end cap suction structure 305, and a tube clamping structure 306. The upper end face of the second support 301 is detachably connected to the lower end face of the three-way moving structure. The end cap suction structure 305, the tube clamping structure 306, and the vision inspection structure 307 are detachably connected to the three-way moving structure via the connecting frame 304. The end cap suction structure 305 is used to move the end cap by suction. The tube clamping structure 306 is used to move the tube by clamping. The three-way moving structure includes a first moving structure 302 for changing the position in the X-axis direction, a second moving structure 303 for changing the position in the Z-axis direction, and a third moving structure 315 for changing the position in the Y-axis direction. The connecting frame 304 is slidably connected to the third moving structure 315, the third moving structure 315 is slidably connected to the second moving structure 303, the second moving structure 303 is slidably connected to the first moving structure 302, and the first moving structure 302 is detachably connected to the second support 301. Optionally, the first moving structure... Structure 302, the second moving structure 303, and the third moving structure can adopt a tracked moving structure; the end cap suction structure 305 includes a suction head, a vacuum negative pressure device, and an end cap rotation mechanism. The suction head is connected to the vacuum negative pressure device. Under the negative pressure of the vacuum negative pressure device, the suction head generates suction, thereby achieving the suction of the end cap. Furthermore, the suction head is also axially connected to the end cap rotation mechanism. The rotation of the end cap rotation mechanism drives the end cap sucked by the suction head to rotate, thereby achieving the adjustment of the end cap angle, thus enabling the secondary positioning of the terminal. The terminal slot for inserting the end cap is optional. The vacuum negative pressure device may include a negative pressure generating device and a pressure regulating device. The negative pressure generating device and the pressure regulating device are electrically connected. The pressure value is preset according to the model of the end cap. The pressure regulating device controls the negative pressure generating device to generate the corresponding negative pressure according to the preset pressure value. The tube clamping structure 306 includes a clamping cylinder and a first clamping claw. The clamping cylinder is connected to the first clamping claw. Preferably, the two clamping claws of the first claw have an arc-shaped structure on opposite sides to adapt to the outside of the tube and achieve better clamping of the tube.

[0064] The tube transfer module 4 includes a fourth support 401, a fourth moving structure 402, and a tube tray 403. The upper end face of the fourth support 402 is detachably connected to the lower end face of the fourth moving structure 402.

These tubes have been aligned during assembly at the welding station and have a specified notch direction. The fourth moving structure 402 is a parallel belt conveyor structure.

[0065] In a preferred embodiment, the secondary positioning sub-module further includes a clamping and flipping structure 312, a second telescopic structure 313, and a pressure block 314;

[0066] The clamping and flipping structure 312 is located on one side of the tube positioning base 311. The lower end face of the clamping and flipping structure 312 is detachably connected to the upper end face of the third telescopic structure, and the lower end face of the third telescopic structure is detachably connected to the upper end face of the third bracket 309. The clamping and flipping structure 312 includes a clamping and flipping cylinder and a second gripper. The clamping and flipping cylinder is connected to the second gripper. When the end cap is fitted into the tube, the second gripper provides downward pressure to the end cap to fix the end cap to the tube. When the end cap is installed on one side of the tube and not on the other side, when the third telescopic structure is in the first position, the second gripper of the clamping and flipping structure 312 clamps the outer wall of the tube 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, the tube flips under the flipping action of the clamping and flipping structure 312 so that after the tube 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.

[0067] The upper end face of the second telescopic structure 313 is detachably connected to the lower end face of the pressure block 314, and the lower end face is detachably connected to the upper end face of the third bracket 309. When the second telescopic structure 313 is in the third position, one end of the lower end face of the pressure block 314 is in contact with the terminal of the tube body, so that the tube body does not rotate when the second gripper provides downward pressure to the end cap. When the second telescopic structure 313 is in the fourth position, the pressure block 314 is not in contact with the terminal of the tube body.

[0068] Optionally, both the second telescopic structure 313 and the third telescopic structure can be electric telescopic rods.

[0069] In an optional embodiment, the end cap feeding module 1 further includes a third slide rail 110, a second connector 111, and a tray gripper 112. The second connector 111 is slidably connected to the third slide rail 110, and the second connector 111 is detachably connected to the tray gripper 112. In this case, the aforementioned first bracket 101, first end cap tray frame 102, end cap tray 103, first slide rail 104, tray tooth structure 105, second slide rail 106, first connector 107, first telescopic structure 108, and second end cap tray frame are all present. The structure consisting of 109 comprises two sets: one set for placing end cap trays 103 with end caps, and the other set for placing empty end cap trays 103 without end caps. When all the end caps in the end cap trays 103 on one second end cap tray rack 109 have been removed, the tray grippers 112 move to the corresponding position under the sliding action of the second connector 111. The tray grippers 112 pick up the empty end cap tray 103, and then move to the corresponding position on the other second end cap tray rack 109 before placing the empty end cap tray 103 down. The other second... The two-end cap tray frame 109 moves to the corresponding position of the other first end cap tray frame 102 under the sliding action of the first connector 107. The other first telescopic structure 108 extends so that the upper end surface of the empty end cap tray 103 on the other second end cap tray frame 109 contacts the lower end surface of the end cap tray 103 located at the bottom of the other first end cap tray frame 102. At this time, the teeth of the other tray inserting tooth structure 105 shorten and the teeth are pulled out 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 frame 109 corresponds to the position of the other tray tooth structure 105. Then the tooth of the other tray tooth structure 105 extends so that the upper end face of the tooth contacts the lower end face of the corresponding end cap tray 103. Then the other first telescopic structure 108 shortens to the preset position. The other second end cap tray frame 109 slides to the preset position on the other second slide rail 106 through the other first connector 107 and continues the next operation.

[0070] In this embodiment, the automatic fuse end cap installation mechanism achieves accurate positioning of the end cap by setting a two-stage positioning structure, ensuring the precision of the installation angle and position of the end cap, reducing the scrap rate. At the same time, the use of automated production improves production efficiency and avoids the phenomenon of crooked caps and difficulty in ensuring tightness that occurs when using manual installation. It also avoids the situation where improper operation or inaccurate equipment adjustment can easily lead to tube damage and increased material loss when using semi-automatic equipment, which is conducive to further improving the product qualification rate.

[0072] Please see Figure 5This application also provides an automatic installation method for fuse end caps, including:

[0073] Step S1: Under the movement of the mobile device, the visual inspection structure 307 takes pictures of the end cap primary positioning tray 2, the tube body transfer module 4 and the secondary positioning sub-module respectively to obtain coordinate images;

[0074] Step S2: Transmit the coordinate image to the image analysis system for image analysis to determine the coordinates of each end cap, each tube body, the secondary positioning structure 310 of the end cap, and the positioning base 311 of the tube body;

[0075] Step S3: The servo controller controls 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, and moves the tube body from the tube body transfer module 4 to the tube body positioning base 311;

[0076] Step S4: Under the control of the servo controller, 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;

[0077] Step S5: Clamp and press down the end cap of the flip structure 312 to complete the fixation of the end cap and the tube body;

[0078] Step S6: The visual inspection structure 307 captures the first inspection image of the tube body after the end caps are installed, and sends the first inspection image to the image analysis system for image analysis;

[0079] Step S7: When the image analysis system determines that the first detection image meets the preset conditions, the clamping and flipping structure 312 flips the tube so that the end cap can be installed on the other side of the tube.

[0080] In one specific embodiment, the automatic installation method for fuse end caps may further include:

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

[0082] The coordinate images of the unpositioned end caps are 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] Based on the terminal slot angle of each unpositioned end cap, the rotation angle corresponding to the end cap absorbing structure 305 in the moving device is analyzed and determined.

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

[0085] Under the movement of the mobile device, the visual inspection structure 307 takes pictures of the end cap primary positioning tray 2, the tube body transfer module 4 and the secondary positioning sub-module respectively to obtain coordinate images;

[0086] The coordinate images are transmitted to the 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 picking structure 305 in the moving device to move the end cap from the end cap primary positioning tray 2 to the end cap secondary positioning structure 310 according to the coordinates. At this time, if there is still a deviation in the terminal slot angle of the end cap, the end cap picking 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 clamping structure 306 in the moving device to move the tube from the tube transfer module 4 to the tube positioning base 311.

[0088] Under the control of the servo controller, the end cap suction structure 305 in the mobile 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.

[0089] The lower end face of the pressure block 314 contacts the upper end face of the tube body under the action of the second telescopic structure 313. At the same time, the second claw in the clamping and flipping structure 312 moves to the upper end face of the end cap under the action of the third telescopic structure, and presses down the end cap under the action of the third telescopic structure to complete the fixing 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 caps have been installed, and sends the first inspection image to the image analysis system for image analysis;

[0091] If 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, and then raises and flips the tube body under the action of the third telescopic structure. After flipping, it is lowered under the action of the third telescopic structure so that the tube body is once again located in the tube body positioning base 311. If 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 scrap area by the tube body clamping structure 306.

[0092] Under the control of the servo controller, the end cap suction structure 305 in the mobile 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.

[0093] The lower end face of the pressure block 314 contacts the upper end face of the tube body under the action of the second telescopic structure 313. At the same time, the second claw in the clamping and flipping structure 312 moves to the upper end face of the end cap under the action of the third telescopic structure, and presses down the end cap under the action of the third telescopic structure to complete the fixing 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 caps have been installed, and sends the second inspection image to the image analysis system for image analysis;

[0095] If the image analysis system determines that the second detection image meets the preset conditions, the tube clamping structure 306 in the moving device moves the tube to the tube tray 403 in the tube transfer module 4 for transfer to the next process; if the image analysis system determines that the second detection image does not meet the preset conditions, an error is reported or the tube is placed in the scrap area by the tube clamping structure 306.

The specific working process of each structure is the same as described in Embodiment 1, and will not be repeated here.
