Description

Technical Field

[0001] The present invention relates to automation equipment, in particular to a terminal adjustment mechanism. Background Art

[0002] With the development of the times, industrial production technology is also developing rapidly, and automation equipment is also being used more and more in industrial production. Multi-core plugs contain multiple terminals for plugging. The terminals of existing multi-core plugs are usually arranged in two rows, upper and lower, which can reduce the lateral size of the plug so that the plug is not too wide. However, in order to facilitate welding the terminals on the wire cores of the wires during the production process, the usual practice is to spread the wire cores flat and then weld the terminals on the wire cores in turn. This will cause the terminals to be arranged in a single row after welding, and due to errors, the spacing between the terminals cannot reach the design value. Therefore, before the terminals and the plug socket are fixed, the upper and lower positions and spacing of the terminals need to be adjusted to make the position of the terminals meet the design value. At present, the above work is usually performed manually, which is relatively inefficient and not conducive to industrial production and large-scale promotion. Summary of the Invention

The front distance adjusting plate 26 is inclinedly provided with N groups of front chutes 261. The number of the front chutes 261 is the same as the number of the front sliders 24. The top ends of each group of front chutes 261 are away from each other and the bottom ends are close to each other. The first roller 220 is located in the rear chute 271, and the second roller 230 is located in the front chute 261. The slide 210, the rear slider 25 and the first clamping piece 6 can move back and forth in the vertical direction under the drive of the stratification cylinder 28. The front distance adjusting plate 26 and the rear distance adjusting plate 27 can move back and forth in the vertical direction under the drive of the distance adjusting cylinder 29.

In this embodiment, the top and bottom ends of the rear chute 271 are smoothly transitioned, and the top and bottom ends of the front chute 261 are smoothly transitioned. ,

[0029] Optionally, in this embodiment, the upper lifting mechanism 4 is an upper lifting cylinder, and the lower lifting mechanism 5 is a lower lifting cylinder.

[0030] In this embodiment, optionally, the first clamping piece 6 and the second clamping piece 7 provided on the upper clamping module 2 have a buffer made of a flexible material fixed on one side contacting the terminal 8, and the first clamping piece 6 and the second clamping piece 7 provided on the lower clamping module 3 have a notch on one side contacting the terminal 8 that matches the shape of the terminal 8. The notch allows the bottom of the terminal 8 to fit into, thereby preventing the terminal 8 from shaking left and right after being clamped. The buffer can squeeze the top of the terminal 8, thereby fixing the terminal 8. At the same time, the flexible buffer can prevent damage to the terminal 8.

[0031] Optionally, in this embodiment, the first clamping piece 6 is detachably fixed to the rear slider 25 by bolts, and the second clamping piece 7 is detachably fixed to the front slider 24 by bolts. The first clamping piece 6 and the second clamping piece 7 are detachably fixed to each other by bolts. The first clamping piece 6 and the second clamping piece 7 are detachably provided so that the user can conveniently replace the first clamping piece 6 and the second clamping piece 7 when they are damaged.

[0032] Movement process: First, align the terminals 8 in a single row state with the first clamping piece 6 and the second clamping piece 7 located on the lower clamping module 3, and ensure that each terminal 8 is respectively clamped in the gap of the first clamping piece 6 and the second clamping piece 7 one by one, and then the lower lifting mechanism 5 drives the lower clamping module 3 upward to approach the upper clamping module 2, and at the same time, the upper lifting mechanism 4 drives the upper clamping module 2 downward to approach the lower clamping module 3, and then the terminal 8 is clamped by the first clamping piece 6 on the upper clamping module 2 and the lower clamping module 3, or is clamped by the second clamping piece 7 on the upper clamping module 2 and the lower clamping module 3, and then the slides 210 on the upper clamping module 2 and the lower clamping module 3 move downward at the same time under the drive of the stratification cylinder 28. Since the first clamping piece 6 and the second clamping piece 7 are spaced apart, The spacing is set, so when the first clamping piece 6 moves downward, the ends of the first clamping piece 6 and the second clamping piece 7 that were originally flush become ups and downs, so that the single row of terminals 8 clamped by the first clamping piece 6 and the second clamping piece 7 are also changed into two rows of terminals 8 staggered up and down, thereby realizing the stratification of the single row of terminals 8, and then the front distance adjusting plate 26 and the rear distance adjusting plate 27 on the upper clamping module 2 and the lower clamping module 3 move upward at the same time under the drive of the distance adjusting cylinder 29. In the initial state, the first roller 220 is located at the top of the rear slide groove 271, and the second roller 230 is located at the top of the front slide groove 261. When the front distance adjusting plate 26 and the rear distance adjusting plate 27 move upward, the first roller 220 moves from the top of the rear slide groove 271 to the bottom of the rear slide groove 271, and the second roller 230 0 moves from the top end of the front slide groove 261 to the bottom end of the front slide groove 261. Since the top ends of each group of rear slide grooves 271 are far away from each other and the bottom ends are close to each other, and the top ends of each group of front slide grooves 261 are far away from each other and the bottom ends are close to each other, the first roller 220 set in the rear slide groove 271 can move closer to each other along the rear slide groove 271 and drive the rear slider 25 and the first clamping piece 6 to move closer to each other. The second roller 230 set in the front slide groove 261 can move closer to each other along the front slide groove 261 and drive the front slider 24 and the second clamping piece 7 to move closer to each other. In this way, the terminals 8 clamped by the first clamping piece 6 and the second clamping piece 7 can also follow the first clamping piece 6 and the second clamping piece 7 to move closer to each other, so that the distance between the terminals 8 reaches the set value, realizing The distance adjustment of the terminal 8, in some optional embodiments, the preset distance between the terminals 8 is adjusted by adjusting the bottom end distance of each group of rear slide grooves 271 and the bottom end distance of each group of front slide grooves 261. After the terminals 8 are layered and distance adjusted, a clamp that matches the current shape of the terminal 8 can be used to clamp the terminal 8 for unloading to ensure that the positional relationship between each terminal 8 remains unchanged. It should be noted that the clamp used for loading and unloading the terminal 8 is not the focus of protection of this embodiment, so it will not be described in detail. Then the upper lifting mechanism 4 drives the upper clamping module 2 to reset, and the lower lifting mechanism 5 drives the lower clamping module 3 to reset to release the terminal 8 to facilitate the unloading of the terminal 8. At the same time, the layering cylinder 28 drives the slide 210 to reset so that the ends of the first clamping piece 6 and the second clamping piece 7 are flush again.The distance adjustment cylinder 29 drives the front distance adjustment plate 26 and the rear distance adjustment plate 27 to reset, so that the first clamping piece 6 and the second clamping piece 7 are separated from each other, so as to facilitate the subsequent loading of the terminal 8. This process is repeated to achieve the automatic layering and distance adjustment of the terminal 8.

[0033] The terminal adjustment mechanism in this embodiment has the advantage of a high degree of automation.
