Description

Technical Field

[0001] This utility model relates to the field of terminal processing equipment technology, and in particular to a positioning mechanism and terminal processing device for a turntable. Background Technology

[0002] Terminals are crucial components in electronic and electrical connections, and their processing accuracy directly affects the reliability and stability of products. In the automated processing of terminals, steps such as cutting, handling, shaping, or inspection are typically performed sequentially. To achieve efficient coordination between these different processes, existing technologies commonly use turntables with multiple accommodating stations as the terminal transfer components.

[0003] In practical applications, a turntable is typically positioned between the terminal cutting station and subsequent processing stations. Multiple receiving stations are circumferentially located on the outer diameter of the turntable. After the terminal is cut and separated from the material strip, it is placed in its corresponding receiving station. The turntable then rotates at a preset angle, sequentially conveying the terminal to the next station for processing, achieving continuous terminal transport and automated production. However, in existing structures, due to gaps, accumulated errors, or drive vibrations in the turntable, positional shifts after rotation can easily occur. This causes the terminal to deviate from its preset position at the processing station, resulting in decreased processing accuracy or even processing failure, severely impacting product quality. Utility Model Content

[0004] The purpose of this application is to provide a positioning mechanism for a turntable to solve the problem of the turntable deviating from a preset position after rotation in the prior art; in addition, the purpose of this application is to provide a terminal processing device including the positioning mechanism for the turntable.

[0008] The fixed end of the drive assembly is mounted on the frame, and the drive end of the drive assembly is connected to the positioning element. The drive assembly is configured to drive the positioning element to a first position or a second position.

[0009] When the drive assembly drives the positioning component to the first position, the positioning component and the turntable do not interfere with each other in the circumferential direction. When the drive assembly drives the positioning component to the second position, the positioning component is located at the corresponding snap-fit ​​station, and the positioning component and the turntable interfere with each other in the circumferential direction.

The positioning member is installed at the first end of the transmission rod along its own length direction.

[0014] The second hinge shaft is located at the second end of the transmission rod along its own length and passes sequentially through the driving end of the driving member and the second end of the transmission rod along the second horizontal direction, so that the driving end of the driving member is hinged to the second end of the transmission rod. The driving member drives the first end of the transmission rod away from the frame along the first horizontal direction, so that the transmission rod, in conjunction with the support plate, drives the positioning member to approach the limiting groove until the positioning member abuts against the inner wall of the limiting groove.

[0030] Please see Figures 1 to 4 As shown in the embodiment of this application, a positioning mechanism for a turntable includes a frame 10, a drive assembly 20, a turntable 30, and a positioning element 40, wherein:

[0031] The turntable 30 is rotatably and horizontally mounted on the frame 10, and the turntable 30 has a number of snap-fit ​​stations 31 evenly distributed along the circumference.

[0032] The fixed end of the drive assembly 20 is mounted on the frame 10, and the drive end of the drive assembly 20 is connected to the positioning member 40. The drive assembly 20 is configured to drive the positioning member 40 to a first position or a second position.

[0033] When the drive assembly 20 drives the positioning member 40 to the first position, the positioning member 40 and the turntable 30 do not interfere with each other in the circumferential direction. When the drive assembly 20 drives the positioning member 40 to the second position, the positioning member 40 is located at the corresponding snap-fit ​​station 31, and the positioning member 40 and the turntable 30 interfere with each other in the circumferential direction.

[0034] The driving component 20 drives the positioning component 40 to switch between the first position and the second position. Then, when the turntable 30 rotates by a preset angle, the positioning component 40 and the turntable 30 interfere with each other in the circumferential direction, thereby achieving precise locking of the turntable 30 and preventing the turntable 30 from shifting due to gaps or vibrations, thus ensuring the stability and accuracy of terminal processing.

[0035] In one embodiment, a limiting groove 32 is provided at the snap-fit ​​station 31 on the turntable 30. The limiting groove 32 has a radial opening facing outwards and the positioning member 40 is adapted to the limiting groove 32.

[0036] The drive assembly 20 includes a drive member 21 and a transmission assembly 22. The drive end of the drive member 21 is connected to the transmission assembly 22 and the positioning member 40 is disposed on the transmission assembly 22. The drive member 21 is configured to drive the positioning member 40 to approach or move away from the limiting groove 32 through the transmission assembly 22.

[0037] By setting a limiting groove 32 on the turntable 30 that is compatible with the positioning member 40, and in conjunction with the positioning member 40, the driving member 21 and the transmission assembly 22, a driving assembly 20 with a simple structure, stable operation and easy observation is provided, thereby improving the efficiency and reliability of the turntable 30 positioning.

[0038] In one embodiment, the transmission assembly 22 includes a support plate 220, a transmission rod 221, a first hinge shaft 222, and a second hinge shaft 223, wherein:

[0039] The support plate 220 is fixedly mounted on the frame 10, and the first hinge shaft 222 is set on the support plate 220 along the first horizontal direction. Figure 1 The first end of the X direction and along the second horizontal direction ( Figure 1 The transmission rod 221 passes through the support plate 220 and the transmission rod 221 in sequence (in the Y direction) so that the middle part of the transmission rod 221 is hinged to the first end of the support plate 220, and the positioning member 40 is installed at the first end of the transmission rod 221 along its own length direction.

[0040] The second hinge shaft 223 is disposed at the second end of the transmission rod 221 along its own length direction and passes through the driving end of the driving member 21 and the second end of the transmission rod 221 in sequence along the second horizontal direction, so that the driving end of the driving member 21 is hingedly connected to the second end of the transmission rod 221. The driving member 21 drives the first end of the transmission rod 221 away from the frame 10 along the first horizontal direction, so that the transmission rod 221 cooperates with the support plate 220 to drive the positioning member 40 close to the limiting groove 32 until the positioning member 40 abuts against the inner wall of the limiting groove 32.

[0041] Specifically, the driving component 21 is configured as a cylinder, which is mounted on the support plate 220 along the first horizontal direction. A hinge block 210 is provided on the telescopic rod of the cylinder, and the cylinder is hinged to the second end of the transmission rod 221 along its own length direction through the hinge block 210.

[0042] By cooperating with the support plate 220, transmission rod 221, first hinge shaft 222 and second hinge shaft 223, a lever-type transmission method with a simple structure and high transmission ratio is provided, which realizes the effective amplification and transmission of driving force, so that the positioning component 40 can stably enter the limiting groove 32, thereby forming reliable interference with the turntable 30 and improving the stability and reliability of positioning.

[0043] In one embodiment, the positioning member 40 is configured as a ring, and the bottom of the limiting groove 32 is configured as an arc structure adapted to the ring.

[0044] By setting the positioning element 40 as a ring and matching the arc structure at the bottom of the limiting groove 32, the positioning element 40 can quickly enter the limiting groove 32, while improving the fit between the positioning element 40 and the limiting groove 32, thereby ensuring the locking and positioning effect of the turntable 30 and improving the positioning accuracy and the stability of the terminal processing process.

[0045] In one embodiment, the ring is rotatably mounted on the transmission rod 221 along its own length.

[0046] By rotatably mounting the ring on the transmission rod 221, adaptive rotation adjustment is achieved when the positioning element 40 contacts the limiting groove 32, reducing the insertion force, reducing wear on parts, and thus extending the service life of the positioning assembly.

[0047] In one embodiment, the opening of the limiting groove 32 is provided with an arc transition surface 320, which extends in the vertical direction.

[0048] By setting an arc transition surface 320 at the opening of the limiting groove 32, the positioning component 40 is smoothly guided into the limiting groove 32, avoiding hard collision between the positioning component 40 and the groove, and further improving the smoothness and reliability of the positioning process.

[0049] In one embodiment, the positioning member 40 includes a first guide slope 41 and a second guide slope 42 arranged in opposite directions and side by side. The connection between the first guide slope 41 and the second guide slope 42 is close to the turntable 30 along the first horizontal direction, and the limiting groove 32 is set as a "V" shaped groove.

[0050] By setting the positioning element 40 to a structure with oppositely inclined guide slopes and cooperating with a "V" shaped groove, the positioning element 40 can be self-guided and inserted into the groove, thereby improving the efficiency and accuracy of the limiting and avoiding misalignment or jamming.

[0051] A terminal processing apparatus comprising a positioning mechanism for a turntable as described in any of the above.

[0052] The working principle of the positioning mechanism used for the turntable is as follows:

[0053] S1, When the cylinder is in the retracted state, the positioning element 40 is in the first position and does not interfere with the turntable 30 in the circumferential direction;

[0054] S2, the turntable 30 rotates at a preset angle under the drive of the external drive component, and the extension end of the cylinder extends so that the positioning component 40 is brought close to the corresponding limiting groove 32 through the transmission rod 221.

[0055] S3, the positioning element 40 enters the limiting groove 32 under the guidance of the guide slope or arc structure and abuts against the inner wall of the groove, thereby interfering with the turntable 30 in the circumferential direction. At this time, the positioning element 40 is in the second position, thereby realizing the positioning of the turntable 30.

[0056] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
