Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a pressing mechanism and production line. Background Technology

[0002] A connector is a device used to connect two active devices. It generally consists of a housing and terminals. The manufacturing process of a connector involves pressing the terminals into the housing.

[0003] The current pressing method involves placing the housing into a simple fixture and then manually pressing the terminals. During the pressing process, the operator mainly relies on experience to manually adjust the position of the terminals, resulting in low pressing efficiency. Furthermore, since some metal pieces on the housing and terminals have slight deformations within the acceptable range, these deformed metal pieces are forcibly squeezed during pressing, which can lead to breakage or scratches, causing a significant increase in the product defect rate. This not only leads to cumbersome subsequent manual repair procedures but also significantly increases the production cost of the product. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] Example 1: Refer to Figures 1-8 As shown, a pressing mechanism of this utility model includes,

[0031] The pressing unit 1 includes a first base 11, a first drive source 12, a slide table 13 and a pressing claw 14. The slide table 13 is slidably disposed on the first base 11. The first drive source 12 is connected to the first base 11 to drive the slide table 13 to slide. The pressing claw 14 is mounted on the slide table 13.

[0032] The auxiliary correction unit 2 includes a second base 21, a second drive source 22, a feeding channel 23, and an auxiliary correction block 24. The second drive source 22 is mounted on the second base 21 and faces the first drive source 12. The feeding channel 23 has a U-shaped channel structure, is connected to the second base 21, and its opening faces the pressing unit 1. The bottom of the feeding channel 23 has through holes 231 corresponding to the positions of the pressing claws 14. The auxiliary correction block 24 includes a main body 241, a guide block assembly 242, and a correction plate 243. The main body 241 is connected to the second drive source 22. The output end corresponds to the position of the through hole 231. On the side of the main body 241 away from the second driving source 22, there are multiple sets of guide block groups 242 arranged at intervals along their length direction. Each set of guide block groups 242 includes multiple guide blocks arranged at intervals along the width direction of the main body 241. At the same time, multiple grooves are opened on the main body 241, which are located between two adjacent guide block groups. A correction plate 243 is embedded in each groove. On the side of each correction plate 243 away from the main body 241, a correction groove 244 extending along the width direction of the main body 241 is opened.

[0033] Specifically, the auxiliary straightening block 24 is used to straighten and guide the metal pieces on the housing 3 and the terminal 4. When the metal pieces have a small deformation within the acceptable range, the auxiliary straightening block 24 can correct and guide the metal pieces in a timely manner, avoiding damage to these metal pieces during the pressing process. Specifically, the straightening plate 243 on the auxiliary straightening block 24 straightens each metal piece on the housing through its straightening groove 244, while the guide block straightens each metal piece on the terminal and guides these metal pieces to be inserted into the predetermined position on the housing.

[0034] Specifically, during the press-fitting of the connector, the feeding device first sends the housing into the feeding channel 23 and moves the housing to the position corresponding to the through hole 231. Then, the second drive source 22 drives the auxiliary straightening block 24 to press against the housing through the through hole 231. The straightening groove 244 on the auxiliary straightening block 24 gradually approaches and engages with the corresponding metal pieces on the housing. During the engagement process, the straightening groove 244 corrects the deformed metal pieces. At the same time, the guide blocks on the auxiliary straightening block 24 are embedded between two adjacent metal pieces. Then, the feeding device will... The terminal is fed onto the pressure claw 14. After the terminal is fixed, the third drive source 18 drives the pressure claw 14 to move so that the terminal moves to the position corresponding to the housing. Then the first drive source 12 is activated, driving the pressure claw 14 to move towards the housing so that the terminal is pressed into the housing. During the pressing process, the guide blocks on the auxiliary correction block 24 will correct and guide the metal pieces on the terminal so that they can be smoothly inserted into the predetermined position of the housing. After the pressing is completed, the first drive source 12, the second drive source 22 and the third drive source 18 are reset, and the product is sent to the next station through the feeding channel 23.

[0035] This utility model discloses a pressing mechanism, which includes a pressing unit 1 and an auxiliary correction unit 2. It can realize automatic pressing between the connector housing and terminals, not only with higher pressing efficiency, but also to limit and unify the pressing degree during the pressing process, ensuring the consistency of the pressing effect. At the same time, the auxiliary correction block 24 is provided to correct and guide the deformation of each metal piece on the housing and terminals during the pressing process, avoiding damage to the metal pieces with small deformation within the acceptable range during the pressing process, thereby improving the yield rate.

[0036] Furthermore, each guide block has a first guide slope at its free end, and each straightening groove 244 has a second guide slope at its opening. It is conceivable that the guide blocks, through their first guide slopes, can guide the metal pieces inserted into the housing and correct their shape; similarly, the second guide slope at the opening of the straightening groove 244 makes the opening of the straightening groove 244 open, guiding the metal pieces on the housing into the straightening groove 244, thereby correcting these metal pieces.

[0037] Furthermore, the side of the correction plate 243 away from the main body 241 has multiple clearance grooves perpendicular to the correction groove to avoid interference between the auxiliary correction block 24 and the shell.

[0038] Furthermore, the main body 241 has at least two first limiting holes extending along its length and sequentially penetrating each groove, and each straightening plate has a second limiting hole perpendicularly corresponding to the position of each first limiting hole. This embodiment provides a connection method for the straightening plate, by setting corresponding first and second limiting holes on the main body 241 and the straightening plate 243, and fixing the straightening plate to the main body 241 by inserting fixing pins, which facilitates the disassembly, assembly, and maintenance of the straightening plate 243. More preferably, the straightening plate 243 can adopt a split structure, specifically, the straightening plate 243 is set as a plate structure composed of two thin plates, and a thinning area is provided on one side of the thin plate near its side, so that when the two thin plates are embedded in the groove, a straightening groove 244 is formed between the thinning areas of the two thin plates.

[0039] Furthermore, a slide block is slidably connected to the second base 21, the output end of the second drive source 22 is connected to the slide block, the auxiliary correction block 24 is disposed on the slide block, and two limiting claws 25 are symmetrically disposed on the slide block, respectively located on both sides of the auxiliary correction block 24. Specifically, the limiting claws 25 can restrict the position of the housing to prevent the housing from moving during the correction and pressing process.

[0040] Reference Figure 5 As shown, further, a sliding groove 232 extending along its length is vertically formed on each of the two side walls of the feeding channel 23. Specifically, a rectangular protrusion extending along its width is provided at each end of the housing. After the housing enters the feeding channel 23, the rectangular protrusions at both ends of the housing are respectively engaged in the sliding grooves 232 on the two side walls of the feeding channel 23, which facilitates the movement of the housing along the feeding channel 23. In addition, the auxiliary straightening block 24 can fix and support the housing when it presses and straightens the housing.

[0041] Reference Figure 3 As shown, further, a baffle 15 is provided on the side of the first base 11 near the second base 21, and a limiting block 16 corresponding to the position of the baffle 15 is connected to the slide 13. Specifically, the stroke of the slide 13 is limited by setting the baffle 15 to avoid overpressure.

[0042] Reference Figure 2As shown, further, a sliding plate 17 is slidably connected to the side of the slide table 13 near the auxiliary correction unit 2. One end of the sliding plate 17 is connected to a pressure claw 14, and the other end is connected to a third drive source 18 for driving the pressure claw to slide to the position corresponding to the through hole 231. Specifically, the arrangement of the sliding plate 17 and the third drive source 18 allows the pressure claw 14 to move within a certain range, which not only facilitates the loading of terminals but also reduces the volume of the pressing unit 1 to a certain extent.

[0043] Furthermore, the pressure claw 14 includes a pressure claw body and a clamping plate. One end of the pressure claw body is connected to the sliding plate 17, and the other end is vertically connected to three parallel clamping plates.

[0044] Example 2: This utility model also discloses a production line, including the pressing mechanism as in Example 1.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
