Description

Technical Field

[0001] This utility model belongs to the field of electronic semi-finished product turnover technology, specifically relating to a turnover mechanism for electronic semi-finished products. Background Technology

[0002] Electronic semi-finished product turnover carts are specialized material handling tools used in electronics manufacturing workshops for short-distance transport of electronic semi-finished products (such as bare PCB boards, pre-assembled components, and unfinished modules). They typically feature multi-layer adjustable shelves or anti-static pallets to accommodate semi-finished products of different specifications, and are equipped with silent casters for flexible movement. Some designs include protective railings to prevent materials from slipping, and most use anti-static materials or coatings to avoid electrostatic damage to electronic components. Their core function is to standardize the flow path of semi-finished products in the workshop, improve material turnover efficiency, and reduce product damage caused by bumps, contamination, and static electricity during handling, thus contributing to the orderly and refined management of the production process.

[0003] Currently, common electronic semi-finished product turnover carts are usually equipped with fixed protective railings to prevent materials from slipping during handling. However, in actual use, due to the diverse sizes and specifications of electronic semi-finished products, the protective structure of these carts is often not flexibly adjustable, making it difficult to adapt to the placement needs of different long products and hindering further turnover work.

[0004] To address the aforementioned issues, this application proposes a turnover mechanism for electronic semi-finished products. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a turnover mechanism for electronic semi-finished products, which features stable turnover.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a turnover mechanism for electronic semi-finished products, including a turnover trolley, and further including: a positioning mechanism, wherein the positioning mechanism is disposed inside the turnover trolley, and a locking mechanism is provided on the top of the positioning mechanism; The positioning mechanism includes: A limiting frame is fixedly connected to the inner side of a turnover trolley. A threaded rod is rotatably connected to the inner side of the turnover trolley. A rectangular block is threadedly connected to the outer wall of the threaded rod. A fixing rod is fixedly connected to the left side of the rectangular block. A positioning plate is fixedly connected to the left end of the fixing rod. A worm gear is fixedly connected to the outer wall of the threaded rod. A worm is meshed with the outer ring of the worm gear.

[0007] Preferably, the limiting frame has an elongated opening on the left side, through which the fixing rod passes and moves, allowing the fixing rod to move through the elongated opening.

[0008] Preferably, the threads on the outer walls of the two ends of the threaded rod are in opposite directions, and the rectangular block is slidably connected to the inner side of the limiting frame, so that the rotation of the threaded rod is converted into the linear motion of the rectangular block.

[0009] Preferably, the inside of the turnover trolley and the top of the limiting frame are both provided with circular holes, and the worm gear passes through the circular holes and rotates to provide stable support for the worm gear.

[0010] Preferably, a handwheel is fixedly connected to the top of the worm gear, so that the worm gear can be rotated by the handwheel.

[0011] Preferably, the locking mechanism includes a fixing groove, and two limiting frames are provided. The fixing groove is fixedly connected to the top of one of the limiting frames. A protrusion is slidably connected to the inner wall of the fixing groove. A geometric block is fixedly connected to the outer side of the protrusion. A magnetic block one is fixedly connected to the top of the protrusion. A magnetic block two is fixedly connected to the top of the fixing groove. An external spline is fixedly connected to the outer side of the protrusion. An internal spline engages with the inner ring of the external spline, which further ensures the stability of the worm gear during rotation.

[0012] Preferably, the internal spline is fixedly connected to the outer wall of the worm, and the back of the fixing groove is open, so that the protrusion can drive the second magnet to move.

[0013] Preferably, the fixing groove has a rectangular opening on the front, and the geometric block passes through the rectangular opening, so that the geometric block can move through the rectangular opening.

[0014] Preferably, the bottom of the second magnetic block is in contact with the top of the protrusion, and the sides of the two in contact are opposite magnetic poles, which facilitates the attraction between the second magnetic block and the first magnetic block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting a transmission mechanism composed of a worm gear, a worm wheel and a forward and reverse threaded rod, the synchronous movement of the two side positioning plates in opposite directions is realized. This can quickly adapt to the clamping and fixing requirements of electronic semi-finished products of different sizes, effectively solve the limitation of the non-adjustable protective structure of the traditional turnover trolley, and significantly improve the trolley's compatibility and turnover efficiency for materials of different specifications.

[0016] In this utility model, the magnetic attraction between magnetic block one and magnetic block two, and the meshing of the external spline and the internal spline, constitute a locking mechanism that is easy to operate and reliable in locking. It can effectively prevent the worm gear from rotating unexpectedly due to vibration during transportation, ensure the stability of the clamping state, and greatly reduce the risk of collision or slippage of electronic semi-finished products due to shaking during turnover.

[0017] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example Please see Figures 1-8The present invention provides the following technical solution: a turnover mechanism for electronic semi-finished products, including a turnover trolley 1, and further including: a positioning mechanism 2, the positioning mechanism 2 is disposed inside the turnover trolley 1, and a locking mechanism 3 is disposed on the top of the positioning mechanism 2. Through the coordinated arrangement of the positioning mechanism 2 and the locking mechanism 3, the flexible clamping of the electronic semi-finished products in the trolley and the reliable locking during the transfer process are realized, which effectively solves the problem that traditional turnover trolleys cannot adapt to materials of various sizes due to the fixed protective structure, and greatly improves the versatility and safety of turnover. Positioning mechanism 2 includes: A limiting frame 21 is fixedly connected to the inner side of the turnover trolley 1. A threaded rod 22 is rotatably connected to the inner side of the turnover trolley 1. A rectangular block 23 is threadedly connected to the outer wall of the threaded rod 22. A fixing rod 24 is fixedly connected to the left side of the rectangular block 23. A positioning plate 25 is fixedly connected to the left end of the fixing rod 24. A worm gear 26 is fixedly connected to the outer wall of the threaded rod 22. A worm 27 is meshed on the outer ring of the worm gear 26. The transmission method of driving the forward and reverse threaded rod 22 by the meshing of the worm 27 and the worm gear 26 is compact, smooth, and self-locking. It ensures that the positioning plates 25 on both sides can move synchronously in opposite directions, realizing fast and accurate clamping and center positioning of materials of different widths.

[0022] Furthermore, the left side of the limiting frame 21 has an elongated opening through which the fixing rod 24 passes and moves. The elongated opening provides good guidance and limitation for the movement of the fixing rod 24, ensuring that the fixing rod 24 and the positioning plate 25 can only move in a horizontal straight line, preventing them from deflecting during the clamping process, and improving the stability and reliability of the operation.

[0023] Furthermore, the threads on the outer walls of the two ends of the threaded rod 22 are in opposite directions, and the rectangular block 23 is slidably connected to the inner side of the limiting frame 21. The design of the positive and negative threads allows the rotation of a single threaded rod 22 to simultaneously drive the rectangular blocks 23 on both sides to complete synchronous opposite or opposite movements. This results in high transmission efficiency, symmetrical structure, and ensures balanced force, avoiding the jamming problem that may be caused by unilateral drive.

[0024] Furthermore, the inside of the turnover trolley 1 and the top of the limiting frame 21 are both provided with round holes. The worm 27 passes through the round holes and rotates. The worm 27 is supported by multiple round holes, which greatly enhances the rigidity and stability of the worm 27 when rotating, reduces vibration and deflection during transmission, and ensures the precise and smooth meshing of the worm 27 with the worm wheel 26.

[0025] Furthermore, a handwheel is fixedly connected to the top of the worm gear 27. The handwheel is designed in accordance with ergonomics, providing operators with a labor-saving and convenient operating method, making the process of adjusting the clamping size easier and more efficient.

[0026] Furthermore, the locking mechanism 3 includes a fixing groove 31, and two limiting frames 21 are provided. The fixing groove 31 is fixedly connected to the top of one of the limiting frames 21. A protrusion 32 is slidably connected to the inner wall of the fixing groove 31. A geometric block 33 is fixedly connected to the outer side of the protrusion 32. A magnetic block 34 is fixedly connected to the top of the protrusion 32. A magnetic block 35 is fixedly connected to the top of the fixing groove 31. An external spline 37 is fixedly connected to the outer side of the protrusion 32. An internal spline 36 engages with the inner ring of the external spline 37. The locking mechanism 3 achieves initial positioning through the magnetic attraction of the magnetic block 34 and the magnetic block 35, and achieves mechanical hard locking through the engagement of the external spline 37 and the internal spline 36. The double protection effectively prevents the worm gear 27 from rotating unexpectedly during transportation vibration, ensuring the absolute reliability of the clamping state.

[0027] Furthermore, the internal spline 36 is fixedly connected to the outer wall of the worm 27, and the back of the fixing groove 31 is open. The internal spline 36 is fixed to the worm 27, realizing the direct connection between the locking action and the transmission shaft. The opening on the back of the fixing groove 31 provides the necessary space for the sliding of the protrusion 32, ensuring the smooth operation of the locking and unlocking actions.

[0028] Furthermore, a rectangular opening is provided on the front of the fixing groove 31, through which the geometric block 33 passes. The rectangular opening precisely restricts the movement trajectory of the geometric block 33, allowing it to move only in the vertical direction, providing the operator with a clear operating feel, while preventing unintended rotation or misalignment of internal components.

[0029] Furthermore, the bottom of the second magnetic block 35 contacts the top of the protrusion 32, and the sides of the two that are in contact with each other are opposite magnetic poles. Utilizing the principle of attraction between opposite magnetic poles, the magnetic attraction between the first magnetic block 34 and the second magnetic block 35 provides a clear "in place" feedback for the locking mechanism 3, and keeps the protrusion 32 in the raised position in the non-locked state, avoiding accidental engagement and improving the intuitiveness of operation.

[0030] Components not described in detail in this article are existing technologies.

[0031] The working principle and usage process of this utility model are as follows: First, place the electronic semi-finished product that needs to be transferred inside the turnover trolley 1. Then, push the geometric block 33 downward, so that the geometric block 33 can drive the protrusion 32 downward, causing the magnetic block 1 34 and magnetic block 2 35 to disengage from each other. At this time, under the action of gravity, the protrusion 32 will slide downward, and the protrusion 32 can drive the magnetic block 2 35 to move, so that the magnetic block 2 35 does not mesh with the internal spline 36. At this time, the worm gear 27 is in a rotatable state, and the worm gear 27 can be further operated. Similarly, the worm gear 27 can also be limited and locked, thereby ensuring the stability of the electronic semi-finished product during transportation and preventing it from being affected by external factors.

[0032] When the worm 27 is de-limited, the handwheel can be turned to rotate the worm 27. The worm 27 meshes with the worm wheel 26, which in turn rotates the threaded rod 22. Since the threads on the outer walls of the two ends of the threaded rod 22 are opposite in direction, and the rectangular block 23 is threadedly connected to the threaded rod 22, the rectangular block 23 can slide and be limited inside the limiting frame 21. Therefore, the rectangular block 23 will move the positioning plate 25 towards the electronic semi-finished product through the fixing rod 24, thus clamping and limiting the electronic semi-finished product for protection. The turnover trolley 1 can also flexibly adjust the clamping and positioning dimensions according to different sizes of electronic semi-finished products, facilitating further turnover work.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
