The interior of the transverse groove is fixed with a straight groove frame bar 12, and the straight groove frame bar 12 is also located at several The inside of the rotating ring 14, and the straight groove frame strip 12 covers the outside of the synchronous toothed belt 10, the straight groove frame strip 12 is open at one end away from the fixed frame 1, and the tooth surface of the synchronous toothed belt 10 slides in contact with the inner wall of the straight groove frame strip 12.

The end of the straight groove frame strip 12 is also provided with a guide component, which facilitates the connector 17 to enter the interior of the straight groove frame strip 12. Through the action of the clamping component, The connector 17 is assembled on the outside of the synchronous toothed belt 10, and the part of the outer ring of the supporting plate 7 protruding from the synchronous toothed belt 10 can support the bottom of the connector 17.

[0032] There are several clamping parts, which are equidistantly distributed on the outside of the synchronous toothed belt 10, and the spacing between two adjacent clamping parts is consistent with the spacing between two adjacent bending parts. The clamping parts include two symmetrically distributed clamping springs 18, which are fixed to the outer wall of the synchronous toothed belt 10 by screws or bonding. The two clamping springs 18 are inclined in the direction of approaching each other, and the movable end of each clamping spring 18 is curved. The curved ends of the two clamping springs 18 make it convenient for the staff to push the connector 17 between the two clamping springs 18. When the clamping spring 18 is elastically deformed, the reaction elastic force generated can elastically clamp and limit the connector 17.

[0033] The guide component includes two first guide warps 19, two third guide warps 41, and one second guide warp 20.

Through the guiding effect of the first guide warp 19, the second guide warp 20 and the third guide warp 41, the connector 17 can follow the transmission of the synchronous toothed belt 10 and smoothly enter the interior of the straight groove frame bar 12.

[0034] The unloading unit includes a gear speed increaser 21 fixed to the upper end of the limiting cover plate 8, and the input end of the gear speed increaser 21 is fixedly assembled with the rotating shaft 42.

A cross bar 26 is slidably assembled between the two optical axes 25, and a pushing component is provided at the bottom of the cross bar 26. The pushing component is used to push downward the connector 17 between the two clamping springs 18, and a touch component is also provided between the output end of the gear speed increaser 21 and the cross bar 26. A second spring 32 is sleeved on the outside of each optical axis 25, and the two ends of the second spring 32 are respectively fixed to the bottom of the cross bar 26 and the mounting bracket 24. The transmission speed of the rotating shaft 42 is increased by the gear speed increaser 21, and the pushing component is frequently moved up and down in cooperation with the action of the touch component, so that the connector 17 can be pushed downward.

[0035] The touch component includes a turntable 22 fixedly assembled at the output end of the gear speed increaser 21, and a plurality of arc-shaped inclined blocks 23 equidistantly distributed around the circumference are fixedly provided at the bottom of the turntable 22.

If the presser foot 29 rests against the upper end surface of the clamping spring 18, the continued downward movement of the first pressure rod 27 will compress the first spring 31; if the presser foot 29 is stuck on the outer wall of the clamping spring 18, the continued movement of the clamping spring 18 will rotate the presser foot 29 and the second pressure rod 28 until the presser foot 29 is separated from the clamping spring 18.

[0037] Example 2: Please refer to Figure 7 This embodiment is a further explanation of the first embodiment. The blanking unit includes a partition layer opened in the middle of one of the synchronous gears 9. A connecting frame 34 is distributed inside the partition layer. The connecting frame 34 is distributed outside the rotating shaft 42, and the connecting frame 34 does not contact the synchronous gear 9. The outer wall of the connecting frame 34 is fixedly provided with a first dome column 35, and the first dome column 35 slides against the arc part of the synchronous toothed belt 10. A sliding rod 38 is fixedly provided at one end of the connecting frame 34 away from the first dome column 35. The axis of the first dome column 35 coincides with the axis of the sliding rod 38, and the axis of the sliding rod 38 intersects perpendicularly with the axis of the rotating shaft 42. The outer surface of the sliding rod 38 is an axial sliding sleeve. A limit seat block 37 is provided, and the limit seat block 37 is fixed to the supporting plate 7. A limit ring 39 is fixedly sleeved on the outer surface of the slide rod 38, and the limit ring 39 is located between the limit seat block 37 and the rotating shaft 42. A third spring 40 is fixedly arranged between the limit ring 39 and the limit seat block 37, and the third spring 40 is sleeved on the outside of the slide rod 38. A toggle component is also provided between the rotating shaft 42 and the connecting frame 34. Through the action of the toggle component, the connecting frame 34 and the slide rod 38 can be frequently laterally displaced, and with the action of the third spring 40, the dome top end of the first dome column 35 can be frequently struck on the arc part of the synchronous toothed belt 10, and it is struck from the inside to the outside.

[0038] The toggle component includes a second dome column 36 fixed to the inner wall of the connecting frame 34, and the second dome column 36 is distributed on the side of the rotating shaft 42 facing the limit seat block 37. The outer surface of the rotating shaft 42 is fixed with several touch rods 33 distributed equidistantly around the circumference. When the rotating shaft 42 rotates with the several touch rods 33, the second dome column 36 can be pushed frequently, causing the sliding rod 38 to be laterally displaced inside the limit seat block 37.

[0039] Working principle: Reference Figure 1 or Figure 3 The left side of the support plate 7 is the loading station, and the right side is the unloading station. Between the loading station and the unloading station are the first bending station, the second bending station, the third bending station, etc. The unloading unit is distributed on the right side of the support plate 7, and the motor 11 is distributed on the left bottom of the support plate 7. The motor 11 can intermittently drive the synchronous belt 10 through the synchronous gear 9, and the spacing of each transmission is the spacing between two adjacent bending plates 16. Moreover, during the transmission process of the synchronous belt 10 with the connector 17, the first bending plate 16 is located between the first row of terminals and the second row of terminals of the connector 17, the second bending plate 16 is located between the second row of terminals and the third row of terminals of the connector 17, and so on.

[0040] The staff loads the connector 17 on the left side of the supporting plate 7. During the loading process, the connector 17 is clamped between the two clamping springs 18 by the raised ends of the two clamping springs 18. The two clamping springs 18 can elastically clamp the connector 17, and the upper end surface of the supporting plate 7 can support the bottom of the connector 17, so that the synchronous toothed belt 10 can smoothly carry the connector 17 into the interior of the straight groove frame 12, and reach the position of the first bending station, and then stop the transmission. At this time, driven by the first cylinder push rod 6, the top plate 3 and the bottom plate 4 are moved toward the fixed frame 1 by one end distance, so that the bending plate 16 can be displaced to the bottom of the terminal of the connector 17 that needs to be bent, and then the second cylinder push rod 43 is operated to make the assembly block 15 turn the bending plate 16 ninety degrees, A row of terminals of the connector 17 can be bent, and then the second cylinder push rod 43 is reset, and the first cylinder push rod 6 also drives the top plate 3 and the bottom plate 4 to reset. At this time, the motor 11 drives the synchronous toothed belt 10 to transmit in sequence, so that the synchronous toothed belt 10 carries the connector 17 that has been bent for the first time to the second bending station for bending the second row of terminals. In this way, multiple rows of terminals of a connector 17 can be bent continuously for multiple times. This conveying and bending method will not affect the staff's continuous loading of the connector 17, thereby realizing continuous bending of batch connectors 17, and there is no need to disassemble and assemble the connector 17 after bending each row of terminals, which greatly improves the bending efficiency of multiple rows of terminals of the connector 17.

[0041] It is worth noting that Figure 1 、 3, 6, and 7, it can be seen that the left end surface of the supporting plate 7 extends out of the outer surface of the synchronous toothed belt 10, and the right end surface of the supporting plate 7 is consistent in size with the right end arc surface of the synchronous toothed belt 10. Therefore, after the bending is completed, the connector 17 will follow the transmission of the synchronous toothed belt 10 and move to the rightmost end of the supporting plate 7. Here, the clamping spring 18 and the connector 17 clamped between the two clamping springs 18 have empty bottoms. When the two clamping springs 18 pass through the arc-shaped transfer, the two clamping springs 18 will expand, so that the clamping of the two clamping springs 18 on the connector 17 is loosened, allowing the connector 17 to automatically fall and be collected by the receiving bucket, thereby completing automatic unloading.

[0042] If the two clamping springs 18 of the same group pass through the circular transfer of the synchronous toothed belt 10, the angle of the two clamping springs 18 will not cause the connector 17 in the middle to fall off. At this time, the unloading unit is required to complete the unloading of the connector 17. There are two unloading methods:

[0043] The first unloading method: reference Figure 6 When the rotating shaft 42 is in transmission, the turntable 22 rotates rapidly. The arc-shaped inclined block 23 presses the contact rod 33, and the second spring 32 elastically resets the cross bar 26, so that the cross bar 26 can move up and down frequently with the second pressure rod 28 and the pressure foot 29. When the connector 17 moves below the pressure foot 29, the connector 17 can be directly pushed down to complete the unloading action.

[0044] The second unloading method: when the rightmost rotating shaft 42 rotates with several contact rods 33, the contact rods 33 can frequently push the second dome column 36 and then release it instantly. Under the action of the third spring 40, the connecting frame 34, the second dome column 36, and the first dome column 35 can be quickly elastically reset, and the first dome column 35 can be elastically knocked on the outer surface of the synchronous toothed belt 10. By knocking on the arc part of the synchronous toothed belt 10 from the inside and the outside, because the synchronous toothed belt 10 is made of flexible material, when the synchronous toothed belt 10 is elastically knocked, it will undergo slight deformation. Since the connector 17 is transferred along the outer wall of the synchronous toothed belt 10, when the connector 17 moves to be perpendicular to the axis of the first dome column 35, it is most affected by the elastic knocking of the first dome column 35. The knocking force it receives is much greater than the elastic clamping force applied to the connector 17 by the two clamping springs 18, which can make the connector 17 pop out from between the two clamping springs 18, completing the unloading action.

[0045] The above-mentioned method can selectively perform assembly of the blanking unit, that is, realize automatic blanking processing of the assembled connector 17 .
