The device 50 is used to place the bundled material strips 200, and the material guiding device 10 is used to feed the needle terminals 100. During the feeding process, the needle terminals 100 are delivered to the adjustment device 20. The adjustment device 20 cooperates with the material guiding device 10 to further feed the needle terminals 100 forward, so that the needle terminals 100 fall onto the material strip 200 passing through the pressing device 30.

[0032] The material guiding device 10 includes a vibrating material tray 11 and an auxiliary tube connected to the vibrating material tray 11. The vibrating material tray 11 generates a vortex force inside the vibrating material tray 11 through vibration, so that the needle terminal 100 is transferred to the auxiliary tube along the delivery pipe on the inner wall of the vibrating material tray 11. In the process of vibration, the vibrating material tray 11 causes the auxiliary tube to vibrate slightly synchronously, and the needle terminal 100 in the auxiliary tube is delivered in a forward and downward direction. In this embodiment, the vibrating material tray 11 adopts an electromagnetic direct vibration feeder.

[0033] The delivery pipe is provided with a material clamping opening, and only the connecting section 110 of the contact pin terminal 100 can be clamped into the material clamping opening and delivered forward along the material clamping opening during the vibration of the vibration disc 11, so that the contact pin terminal 100 is preliminarily arranged on the delivery pipe, that is, the welding cups 120 between the contact pin terminals 100 are arranged on the same side.

[0034] The adjustable support frame 40 comprises two support plates 41 arranged oppositely, a position adjusting plate 42 arranged between the two support plates 41, and a fixing member penetrating through the support plates 41 and being screwed with the position adjusting plate 42.

[0036] The pressing device 30 includes a base 34, a limiting plate 33, a first pressing assembly 31 and a second pressing assembly 32. The limiting plate 33, the first pressing assembly 31 and the second pressing assembly 32 are all installed on the base 34. The limiting plate 33 is located at the rear position of the limiting section 22. The limiting plate 33 and the limiting section 22 form a blanking space 90. The first pressing assembly 31 includes a slider 312, a guide rail 311, a first driving cylinder 313 and a first pressing plate 314. The guide rail 311 is installed on the base 34. The first driving cylinder 313 is installed on the guide rail 311. The slider 312 is installed in conjunction with the guide rail 311. The first pressing plate 314 is connected to the slider 312. The first driving cylinder 313 drives the slider 312 and the first pressing plate 314 to move in the vertical direction, so that the first pressing plate 314 extends out from the blanking space 90.

[0037] The second pressing assembly 32 includes a second driving cylinder 321 and a pressing block 322 connected to the second driving cylinder 321.

[0038] The automatic taping device for D-SUB needle terminals also includes a positioning device 80. The material strip 200 is provided with spaced-apart perforations 230. The positioning device 80 includes a drive motor 81 and a gear 82 connected to the drive motor 81. The gear 82 is buckled on the perforations 230 on the material strip 200. When the drive motor 81 drives the gear 82 to rotate, the gear 82 is buckled on the perforations 230 of the material strip 200 in turn, thereby driving the material strip 200 to feed forward.

[0039] The following is a detailed description of the automatic taping process for D-SUB terminals:

[0040] Initially, the needle terminal 100 is placed in the vibrating material tray 11, the material strip 200 passes through the base 34 and is wrapped around the material receiving device 60, the gear 82 is buckled on the through hole 230 of the material strip 200, and the vibrating material tray 11 is started. During the vibration process, the vibrating material tray 11 causes the auxiliary tube and the material guiding device 10 to vibrate slightly synchronously, and drives the auxiliary tube and the needle terminal 100 on the steering device 20 to be delivered in the forward and downward direction (i.e., obliquely downward direction). The needle terminal 100 enters the conveying section 21 of the steering device 20, and the convex ring 140 of the needle terminal 100 is clamped into the first clamping groove 212, and then falls from the outlet of the first channel 211 of the conveying section 21 into the second channel 221 of the limiting section 22, and the convex ring 140 of the needle terminal 100 is clamped into the second clamping groove 222. When the needle terminal 100 falls into the second channel 221, the arc-shaped notch 130 is provided on the solder cup 120 of the needle terminal 100, which causes the gravity of the needle terminal 100 to shift, and the vibrating material plate 11 provides a forward and downward delivery force, so that the arc-shaped notch 130 of the needle terminal 100 is adjusted backward and downward, and then when the needle terminal 100 falls into the limiting section 22, the arc-shaped notch 130 of the needle terminal 100 is buckled on the limiting ridge 223. When it is further delivered forward, due to the limitation of the limiting ridge 223, the needle terminal 100 will not flip over at will. When the needle terminal 100 is delivered to the exit of the limit section 22, the sensor detects the front needle terminal 100, and the first driving cylinder 313 of the first pressing assembly 31 drives the first pressing plate 314 to press down until the needle terminal 100 is stuck in the blocking piece group 210 of the material strip 200. The positioning device 80 drives the material strip 200 to be further delivered forward through the gear 82, so that the next blocking piece group 210 moves to the bottom of the blanking space 90. The second pressing assembly 32 presses down the needle terminal 100 on the path again to ensure that the needle terminal 100 is stuck in place on the material strip 200.

[0041] The beneficial effect of the automatic taping device for D-SUB needle terminals of the present invention is that: by providing the adjustment device 20, and the vibrating material disk 11 providing a forward and downward delivery force, the adjustment device 20 cooperates with the vibrating material disk 11 to feed and adjust the needle terminals 100, thereby ensuring that the orientations of the needle terminals 100 are consistent, and the pressing device 30 assembles the adjusted needle terminals one by one onto the material tape 200. The entire assembly process has a high level of automation, effectively improving processing efficiency and saving labor costs.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of protection of the present application.
