Description

Technical Field

[0001] This application relates to the field of automated equipment, and in particular to a locking mechanism for a semi-automated testing device. Background Technology

[0002] Semi-automated testing equipment typically refers to devices or systems that partially rely on automation technology while still requiring human intervention during the testing process. These devices can improve testing efficiency and accuracy and are suitable for software testing, hardware testing, and quality inspection of various products.

[0003] Existing technologies (such as Chinese patent CN117872140A) disclose a testing device, but in actual use, the applicant discovered serious dynamic stability problems: Traditional trays, when rotating with a servo motor or switching workstations, lack an active rigid locking mechanism and rely solely on gravity or simple slot limits. Under the inertial force generated by high-speed start-stop, the trays are prone to minute horizontal displacements or vibrations. Even millimeter-level offsets can cause misalignment between the test probe and the tested product (such as the tabs of a pouch battery), resulting in false "defective" products and severely impacting test yield and the continuity of automated processes. Furthermore, traditional mechanical locking structures are often complex and cumbersome to operate, making it difficult to achieve millisecond-level rapid response. Therefore, there is an urgent need for a locking mechanism that can achieve rapid and stable locking through electronic control and resist motion inertia. Utility Model Content

[0004] To address the issue of insufficient locking of the container components, this application provides a locking mechanism for a semi-automatic testing device.

[0005] The locking mechanism of the semi-automatic testing device provided in this application adopts the following technical solution:

[0006] A locking mechanism for a semi-automatic testing device includes a device body, an inner wall of which is provided with a mounting plate, a change button is fixedly connected to the inner wall of the device body, and a locking mechanism is provided on the top of the mounting plate.

[0007] The locking mechanism includes a tray mounted on the top of a mounting plate. A limiting ring is fixedly mounted on the top of the tray. A sleeve is provided on the inner wall of the limiting ring. A limiting bead is slidably mounted on the side wall of the sleeve. A protrusion abuts against the side wall of the sleeve on the inner wall of the limiting ring. A partial gap is left between the side wall of the sleeve and the inner wall of the limiting ring. When the limiting bead protrudes outward, it abuts against the upper surface of the protrusion on the inner wall of the limiting ring. The side wall of a sliding post fits against the side wall of the limiting bead. Multiple limiting beads are symmetrically arranged on the side wall of the sleeve. A snap-fit ​​groove is opened on the side wall of the sliding post. The cross-sectional height of the snap-fit ​​groove is consistent with the diameter of the limiting bead. A conductor is fixedly mounted on the top of the mounting plate. A magnetic sheet is fixedly mounted on the top of the conductor. An attraction sheet is provided on the bottom of the sleeve. A sliding post is fixedly mounted on the top of the attraction sheet.

[0008] By adopting the above technical solution, the sliding columns are symmetrically arranged around the center line of the tray, thereby making the locking more stable.

[0009] Preferably, the locking mechanism further includes a placement platform fixedly connected to the top of the mounting plate. A positioning cylinder is fixedly passed through the top of the placement platform. A positioning rod is fixedly connected to the top of the positioning cylinder. A positioning ring is movably passed through the outer wall of the positioning rod. The outer wall of the positioning ring is fixedly passed through the top of the tray. The bottom of the tray is in contact with the top of the placement platform. A flat ring is fixedly passed through the top of the tray. The bottom of the flat ring is fixedly connected to the top of the limiting ring. A connecting piece is threadedly connected to the top of the placement platform.

[0010] By adopting the above technical solution, the diameters of the limiting ring and the flat ring are kept consistent, thus making the fixation more consistent and avoiding structural failures.

[0011] Preferably, a sleeve is fixedly connected to the top of the connector, and a sliding hole is provided through the side wall of the sleeve.

[0012] By adopting the above technical solution, the sliding hole is horizontally symmetrically pierced through the center, thus facilitating subsequent linkage.

[0013] Preferably, the inner wall of the sliding hole is slidably connected to a plurality of limiting beads, and the top of the sleeve is provided with a sliding circular hole.

[0014] By adopting the above technical solution, the size of the limiting bead is matched with the cross-sectional size of the sliding hole, thereby making the connection tighter.

[0015] Preferably, the inner wall of the sliding circular hole is slidably connected to the outer wall of the sliding column.

[0016] By adopting the above technical solution, the size of the snap-fit ​​groove and the limiting bead are matched, so that the snap-fit ​​groove can limit the limiting bead.

[0017] Preferably, the bottom of the sliding column is fixedly connected to the top of the suction plate, and the side wall of the suction plate is slidably connected to the inner wall of the connector.

[0018] By adopting the above technical solution, the diameter of the suction plate is matched with the inner diameter of the connector, thereby making the connection tighter.

[0019] Preferably, the bottom of the attraction piece is attached to the top of the magnetic piece, and the side wall of the magnetic piece is fixedly connected to the inner wall of the connector.

[0020] By adopting the above technical solution, the diameter of the magnetic strip is matched with the inner diameter of the connector, thereby enabling the magnetic strip to have sufficient attraction for the attraction plate.

[0021] Preferably, the conductor is fixedly placed through the bottom of the platform, and the top of the conductor is fixedly connected to the bottom of the magnetic sheet.

[0022] By adopting the above technical solution, the bottom of the conductor is provided with a connection end that can be connected to the current transmission line, thereby facilitating the control of the positive and negative poles of the current transmitted by the current transmission line, and thus controlling whether the conductor carries a positive or negative pole.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The tray moves vertically downwards, causing the limiting ring to fit onto the outer wall of the connector. The current to the input conductor is switched via a changeover button, causing the magnetic plate and the attraction plate to carry the anisotropic electrode. This causes the attraction plate to move towards the magnetic plate, pulling the sliding column towards it. The limiting bead, limited by the sliding column, slides outwards, abutting against the limiting ring, thus locking the tray. This ensures that when the placement platform moves synchronously with the tray, it secures and locks the tray, preventing tray misalignment during movement, thus avoiding disruptions to the automated process, reducing motion malfunctions during device use, and improving overall device efficiency.

[0037] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0038] This application discloses a locking mechanism for a semi-automatic testing device.

[0039] Reference Figure 1 A locking mechanism for a semi-automatic testing device includes a device body 1, a mounting plate 11 disposed on the inner wall of the device body 1, a change button 12 fixedly disposed on the inner wall of the device body 1, and the change button 12 can control the switching of the positive and negative poles of the charge input at the bottom connection end of the conductor 217. A locking mechanism 2 is disposed on the top of the mounting plate 11.

[0040] The staff placed the mounting plate 11 inside the main body 1 of the device, and then placed the placement platform 21 on top of the mounting plate 11, ready for installation.

[0041] Reference Figure 2 - Figure 6The locking mechanism 2 includes a tray 25 fixedly mounted on the top of the mounting plate 11, a limiting ring 27 fixedly mounted on the top of the tray 25, a socket 29 disposed on the inner wall of the limiting ring 27, a conductor 217 fixedly mounted on the top of the mounting plate 11, a magnetic sheet 216 fixedly mounted on the top of the conductor 217, an attraction sheet 215 disposed on the bottom of the socket 29, a sliding post 213 fixedly mounted on the top of the attraction sheet 215, and a limiting bead 211 slidably disposed on the side wall of the socket 29. The locking mechanism 2 also includes a placement platform 21 fixedly connected to the top of the mounting plate 11, with a through opening at the top of the placement platform 21. A positioning cylinder 22 is fixedly connected to the placement platform 21 through a first circular hole. A positioning rod 23 is fixedly connected to the top of the positioning cylinder 22 for easy positioning. A second circular hole is provided through the top of the positioning ring 24, through which the outer wall of the positioning rod 23 moves, allowing the positioning rod 23 to be inserted into the positioning ring 24. The diameter of the positioning ring 24 is the same as the diameter of the positioning cylinder 22, ensuring alignment during installation. A third circular hole is provided through the top of the tray 25, through which the positioning ring 24 is fixedly connected to the tray 25. The top of the positioning ring 24 and the top of the tray 25 remain horizontal, ensuring the flatness of the top of the tray 25.

[0042] The operator first aligns the bottom of the positioning ring 24 with the top of the positioning cylinder 22, then aligns the hole in the middle of the positioning ring 24 with the positioning rod 23. The tray 25 is then moved vertically downwards, allowing the positioning ring 24 to engage with the positioning rod 23, thus positioning the tray 25. As the tray 25 moves downwards, the center of the socket 29 aligns with the center of the flat ring 26 due to the positioning of the positioning ring 24 and the positioning cylinder 22. With the tray 25 moving vertically downwards, the limiting ring 27 and the flat ring 26 are fitted onto the outer wall of the socket 29, and the protruding part of the inner wall of the limiting ring 27 fits against the outer wall of the socket 29 and slides downwards.

[0043] Reference Figure 2 - Figure 7The top of the placement platform 21 is attached to the bottom of the tray 25. A circular hole four is provided through the top of the tray 25. A flat ring 26 is fixedly connected to the circular hole four, thus fixing the flat ring 26 to the tray 25. The top of the limiting ring 27 is fixedly connected to the bottom of the flat ring 26. The outer wall of the limiting ring 27 is fixedly connected to the circular hole four, thus fixing the limiting ring 27 to the tray 25. The inner wall of the limiting ring 27 is provided with an arc-shaped protrusion. A threaded hole is provided on the top of the placement platform 21 (not through). The connector 28 is threaded into the threaded hole, thus connecting the connector 28 to the threaded hole. 8 is threadedly connected to the placement platform 21. The socket 29 is fixedly connected to the top of the connector 28. The protruding end of the inner wall of the limiting ring 27 fits against the outer wall of the socket 29. The sliding hole 210 is opened through the side wall of the socket 29. Multiple limiting beads 211 are slidably connected to the inner wall of the sliding hole 210, so that the limiting beads 211 can slide horizontally. The limiting beads 211 are made of metal so that the limiting beads 211 can be continuously attracted by the sliding column 213. The diameter of the limiting ring 27 and the flat ring 26 are consistent, so that the connection is more stable.

[0044] Subsequently, the staff controlled the bottom of the conductor 217 to input a charge of opposite polarity to that of the attraction piece 215 via the change button 12. This caused the magnetic piece 216 and the attraction piece 215 to carry opposite magnetic poles through the conductor 217, causing the magnetic piece 216 to attract the attraction piece 215 to move vertically downwards. The attraction piece 215 then drove the sliding column 213 to move vertically downwards. As the sliding column 213 moved vertically downwards, it slid the limiting bead 211 from the side close to the sliding column 213 to the side away from the sliding column 213 through the snap-fit ​​groove 214 on the side wall. This caused the limiting bead 211 to protrude from the side wall of the sleeve 29, making the limiting bead 211 abut against the top of the inner protrusion of the limiting ring 27. This prevented the conductor 217 from moving vertically, thus fixing the tray 25 to the placement platform 21 through the conductor 217, thereby locking the tray 25.

[0045] Reference Figure 6 - Figure 8A sliding circular hole 212 is formed through the top of the sleeve 29, and a circular hole 5 is formed through the top of the connector 28, corresponding to the sliding circular hole 212. The outer wall of the sliding column 213 is slidably connected to the inner wall of the sliding circular hole 212. A snap-fit ​​groove 214 is formed on the side wall of the sliding column 213, so that when the sliding column 213 moves vertically, it can drive the limiting bead 211 to move horizontally. The top of the suction piece 215 is fixedly connected to the bottom of the sliding column 213, so that the sliding column 213 can drive the suction piece 215 to move vertically. The side wall of the suction piece 215 is in contact with the inner wall of the connector 28. The attraction piece 215 is slidably connected to the connector 28, and the bottom of the attraction piece 215 is in contact with the top of the magnetic piece 216, so that the attraction piece 215 can be affected by the magnetic pole of the magnetic piece 216. The side wall of the magnetic piece 216 is fixedly connected to the inner wall of the connector 28, so that the magnetic piece 216 and the connector 28 are fixedly connected. A circular hole 6 is opened through the bottom of the placement platform 21, and the conductor 217 is fixedly connected through the circular hole 6, so that the conductor 217 is fixedly connected to the placement platform 21. The bottom of the magnetic piece 216 is fixedly connected to the top of the conductor 217.

[0046] Subsequently, when it is necessary to unlock, the operator uses the change button 12 again to make the magnetic plate 216 and the attraction plate 215 have the same magnetic poles, so that the magnetic plate 216 and the attraction plate 215 repel each other. Since the magnetic plate 216 is in a fixed state, the attraction plate 215 will move vertically upward. The attraction plate 215 will drive the sliding column 213 to move vertically upward. When the sliding column 213 moves vertically upward, the locking groove 214 will align with the sliding hole 210. The limiting bead 211 is attracted by the sliding column 213, so that the limiting bead 211 moves horizontally to the side of the sliding column 213, so that the limiting bead 211 engages with the locking groove 214, thereby releasing the limiting bead 211 from limiting the limiting ring 27, so that the limiting ring 27 can move vertically, thereby releasing the fixation of the tray 25 and completing the disassembly of the tray 25.

[0047] The change button 12 and the conductor 217 are existing technologies, and their structural principles will not be described in detail. They also include power connection lines, sensors, terminal blocks, charge transport lines, etc., which are not the main technologies and will not be described in detail.

[0048] The implementation principle of the locking mechanism of a semi-automatic testing device in this application embodiment is as follows:

[0049] First, the operator aligns the bottom of the positioning ring 24 with the top of the positioning cylinder 22. Then, the tray 25 is moved vertically downwards, allowing the positioning ring 24 to engage with the positioning rod 23. As the tray 25 moves downwards, the limiting ring 27 and the flattening ring 26 are fitted onto the outer wall of the socket 29. The operator then uses the changeover button 12 to input a charge of opposite polarity to the attracting plate 215 at the bottom of the conductor 217, causing the magnetic plate 216 to attract the sliding column 213 downwards. As the sliding column 213 moves downwards, it drives the limiting bead 211 through the snap-fit ​​groove 214 on the side wall. The side of the limiting bead 211 closest to the sliding column 213 slides away from the sliding column 213, thus allowing the limiting bead 211 to move. The side of the positioning bead 211 is exposed on the side wall of the sleeve 29, thereby fixing the tray 25 to the placement platform 21 through the conductor 217. Then, when it is necessary to unlock, the operator uses the change button 12 again to make the magnetic plate 216 and the attraction plate 215 have the same magnetic poles, so that the attraction plate 215 will move vertically upward. The attraction plate 215 will drive the sliding column 213 to move vertically upward. The locking groove 214 will align with the sliding hole 210. The limiting bead 211 is attracted by the sliding column 213, so that the limiting bead 211 moves horizontally to the side of the sliding column 213, so that the limiting bead 211 engages with the locking groove 214, thereby releasing the limiting bead 211 from limiting the limiting ring 27, and thus releasing the fixation of the tray 25.

[0050] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
