Description

Technical Field

[0001] The present invention relates to the field of docking technology, and in particular to a docking engaging device suitable for operation scenarios such as docking devices and connectors. Background Art

[0002] In SMT electronic equipment production, material transport carts are often loaded and unloaded manually, making it impossible to directly connect the carts to the loader conveyor tracks, resulting in time-consuming and labor-intensive material turnover. Furthermore, some production conveyors lack flexible connections, requiring numerous adjustments to production lines.

[0003] In view of the above problems, the present invention proposes a docking and locking device to achieve connection between the two ends through flexible assembly, so as to improve production efficiency and adaptability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a docking and locking device with a simple structure and convenient operation in response to the current status of the existing technology, so as to achieve fast and reliable mechanical locking between docking components, solve the problems of inconvenient docking of material transport vehicles, poor connection flexibility of conveyors and cumbersome adjustment in the existing SMT electronic equipment production, and improve production efficiency and production line adaptability.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a docking and locking device, including a docking head (A) and a socket element (B) that docks with the docking head (A); wherein the docking head (A) includes an external component and an internal component.

[0006] The external component consists of a butt joint positioning seat (1), an annular shell (2), a butt joint shell (3), a locking cam (4) and a conical pin (5).

[0007] The internal component consists of a one-degree-of-freedom shaft (6), an on-shaft pull rod component (7), a flat key (8), an on-shaft spring positioning component (9), and a torsion spring (10).

[0008] The socket element (B) is a docking socket element (11), and the inner side of its shell is provided with a snap-fitting notch that matches the snap-fitting cam (4).

[0009] In order to achieve stable connection and coordinated operation of the various components of the docking joint, among the external components, the docking joint positioning seat (1), the annular shell (2) and the docking joint shell (3) are all connected by threads to ensure the stability of the connection; the engaging cam (4) is embedded in the docking joint shell (3) through the conical pin (5), so that the engaging cam (4) can rotate around the conical pin (5), providing a basis for the engaging action.

[0010] The matching relationship of the internal components is as follows: the shaft body (6) is limited between the joint positioning seat (1) and the joint housing (3) to ensure that the axial position of the shaft body (6) is stable; the shaft body (6) is connected to the shaft pull rod component (7) and the shaft spring positioning component (9) through the flat key (8), which not only realizes the power transmission between the shaft body (6) and these shaft components, but also plays a limiting role on the shaft components to prevent them from excessive axial movement along the shaft body (6); one end of the torsion spring (10) is buckled on the shaft spring positioning component (9), and the other end is buckled on the engaging cam (4). By utilizing the torsion force of the torsion spring (10), the engaging cam (4) can be automatically ejected, so that it is engaged in the engaging notch of the socket component (11) to complete the engaging action.

[0011] In order to realize the function of releasing the engagement, a pull rod limiting groove is provided on the side of the annular housing (2), and the pull rod component (7) on the shaft can move back and forth in the limiting groove, thereby driving the shaft body (6) to move synchronously. Through the cooperation of the shaft body (6) and other components, the tightening control of the engaging cam (4) is realized, thereby releasing the engaging state.

[0012] The structural design of the joint housing (3) has multiple functions: cam notches are left on three sides at equal angles, providing space for the ejection and retraction of the engaging cam (4); the disc at the tail is provided with four positioning screw holes, which facilitates the installation and positioning of the joint; at the same time, the tail and the front disc of the annular housing (2) are alternately cut at 45 degrees to the threaded hole. This design facilitates the use of tools to perform threaded connection operations on the positioning seat (1), thereby improving assembly convenience.

[0013] Three notches are reserved at the bottom of the joint positioning seat (1). This design provides operating space for the threaded connection between the positioning seat (1) and the annular shell (2), facilitating the assembly and fixation of the two, and also helps to ensure the positioning accuracy of the butt joint end and the accuracy of the butt joint process.

[0014] The docking process of the present invention is as follows: in the initial state, the pull rod member (7) on the shaft is in the rear position, and under the torsional force of the torsion spring (10), the engaging cam (4) pops out normally; when the docking head (A) is inserted into the socket element (11), the engaging cam (4) is blocked by the shell of the socket element (11) and is forced to be retracted into the cam slot of the docking head shell (3); as the insertion stroke advances, when the engaging cam (4) moves to the engaging slot position of the socket element (11), the obstruction disappears, and the engaging cam (4) automatically pops out under the action of the torsion spring (10) and is engaged in the engaging slot, thereby achieving a stable engagement between the docking head (A) and the socket element (B).

[0015] When the docking needs to be released, the pull rod member (7) on the shaft is pushed forward along the limit groove on the side of the docking joint housing (3), driving the shaft body (6) and the spring positioning member (9) on the shaft to move synchronously, so that the torsion spring (10) is further twisted and force is accumulated. At the same time, the shaft member drives the engaging cam (4) to overcome the force of the torsion spring (10) and rotate around the conical pin (5), and retract it into the cam groove of the docking joint housing (3). At this time, the docking joint (A) can be pulled out from the socket component (B) to complete the unlocking.

[0016] Compared with the existing technology, the advantages of the present invention are: it adopts a purely mechanical structure to achieve engagement and unlocking, with a simple structure, low manufacturing cost and high reliability; it uses a torsion spring to provide automatic engagement force, and the design of the engagement cam and the engagement slot ensures a stable engagement and a good docking effect; unlocking can be achieved through a pull rod component, which is easy to operate and can quickly complete the docking and separation actions, thereby improving work efficiency; threaded connections, flat key connections and other methods are mostly used between the various components, which are easy to assemble and maintain; the design of the positioning seat and the annular shell ensures the accuracy of docking positioning, which helps to improve the docking accuracy; it can flexibly adapt to different docking scenarios, such as the docking of material transport vehicles and loader conveyor belt tracks, the connection between production conveyors, etc., thereby enhancing the adaptability of the production line and the convenience of adjustment.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example 1: See Figure 2 The docking and locking device of the present invention is composed of a docking head A and a socket component B, and realizes rapid docking and stable locking through the mechanical linkage of each component. It is suitable for the docking of material transport vehicles and loader conveyor belt tracks in SMT electronic equipment production, and the connection between production conveyors.

[0031] The assembly process of connector A is as follows:

[0032] Internal components see Figure 4 , the assembly is carried out with the shaft body 6 as the core: the upper pull rod component 7 and the upper spring positioning component 9 are first connected to the shaft body 6 through the flat key 8 to ensure synchronous movement with the shaft body. The upper pull rod 7 on the shaft body is placed in the groove of the annular shell 2, and then covered with the positioning seat 1 to prevent excessive movement; the two ends of the shaft body 6 are respectively inserted into the center holes of the docking head positioning seat 1 and the docking head shell 3, and axial limitation is achieved by the steps in the holes; one end of the torsion spring 10 is connected to the upper spring positioning component 9, and the other end is connected to the engaging cam 4. In the natural state, the torque is relied on to keep the rear end of the engaging cam 4 in a pop-up state.

[0033] When assembling external components, refer to Figure 3 After the shaft body 6 and the associated components are inserted into the joint housing 3, the joint housing 3 and the annular housing 2 are fixed with threads, and the pull rod component 7 on the shaft is installed on the shaft body 6 along the groove of the annular housing 2, and then the positioning seat 1 and the annular housing 2 are fixed with threads to form a complete external frame; the other end of the torsion spring 10 is inserted into the reserved groove of the engaging cam 4 to ensure that the engaging cam 4 can be ejected and limited normally; the engaging cam 4 is installed in the cam groove of the joint housing 3 through the conical pin 5, and can rotate flexibly around the conical pin 5, and the groove reserves enough space for its movement.

[0034] The inner side of the socket element 11 that is connected to the socket element B is provided with a locking notch that is adapted to the locking cam 4. The position of the notch corresponds to the cam pop-up trajectory to ensure accurate locking during docking.

[0035] The device operates as follows: Before docking, the upper pull rod 7 is positioned at the rear end of the retaining groove in the annular housing 2, and the engaging cam 4 is naturally ejected by the torsion spring 10. When the docking head A is inserted into the socket B, i.e., the socket element 11, the engaging cam 4 is blocked by the housing and rotates inward, compressing the spring. When inserted into the corresponding position, the cam aligns with the groove, and the spring returns to push the cam into the groove, completing the docking engagement.

[0036] When unlocking, the pull rod component 7 on the shaft is pushed forward along the limit groove, driving the shaft body 6 and the spring positioning component 9 on the shaft to move. The torsion spring 10 is pulled and slightly twisted, and the cam is retracted into the housing under the tension. At this time, the docking joint A can be pulled out, and the components will automatically reset after releasing the pull rod.

[0037] This embodiment 1 realizes rapid docking and unlocking without the need for additional power through the coordinated cooperation of the mechanical structure, and is easy to operate and has a reliable connection.

[0038] Example 2: This differs from Example 1 in that the number of engaging cams 4 can be adjusted to two or four based on the required docking strength, evenly distributed around the circumference of the docking head housing 3. Accordingly, the engaging notches of the socket element 11 can be adjusted accordingly. Furthermore, the torsion spring 10 can be replaced with a tension spring, one end of which is connected to the engaging cam 4 and the other end is fixed to the spring positioning member 9 on the shaft. The tension forces the engaging cam 4 to eject. The remaining structure and operating principle are identical to Example 1.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
