[0035] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0036] This embodiment discloses a USB connector welding device, which is used to weld a USB housing and a matching PCB board together, thereby assembling a USB connector.

[0037] like Figures 1 to 5 The welding device in this embodiment includes: a frame 1, a first feeding mechanism 2, a driving mechanism 3, a second feeding mechanism and a first welding mechanism 5.

[0038] The frame 1 is used to provide a support carrier, and is provided with at least one first slide groove 10, in which the USB housing can slide from one end to the other end. In order to improve the working efficiency, in this embodiment, two parallel first slide grooves 10 are provided on the frame 1, and when the USB housing enters the frame 1, it moves in the first slide groove 10 in a stepping manner.

[0039] The first feeding mechanism 2 is used to feed the USB shell into the first chute 10. The first feeding mechanism 2 is arranged at one end of the frame 1, and includes a first feeding platform 20 and a pusher 21. The first feeding platform 20 is provided with a first opening 200 docking with the first chute 10 and a second opening 201 for receiving the USB shell. The pusher 21 is used to push the USB shell entering the first feeding platform 20 to the first opening 200. During operation, the second opening 201 docks with the vibrating feeding plate, so that the USB shells are automatically fed into the first feeding platform 20 from the second opening 201 one by one, and the USB shells are pushed to the position of the first opening 200 in a fixed posture by the pusher 21. In the case where two first chute 10 are arranged on the frame 1, correspondingly, two second openings 201 corresponding to the two first chute 10 are arranged on the first feeding platform 20, and a pusher 21 is arranged for each second opening 201, and the two pushers 21 push the USB shell to the first opening 200 alternately.

[0040] The driving mechanism 3 is used to drive the USB housing to move from the first opening 200 to the first slide groove 10 in a stepping manner. That is, when the pushing member 21 pushes the USB housing to the first opening 200, the driving mechanism 3 pushes the USB housing into the first slide groove 10 and pushes the USB housing to move stepwise in the first slide groove 10.

[0041] The second loading mechanism includes a transfer mechanism 40 and a suction head 41 installed on the transfer mechanism 40 . The suction head 41 is used to absorb the PCB board. The transfer mechanism 40 is used to drive the suction head 41 to move so as to move the PCB board onto the USB housing located in the first slide groove 10 .

[0042] The first welding mechanism 5 is arranged above the first slide slot 10, and is used to perform welding operations on the corresponding parts of the USB housing and the PCB board located in the first slide slot 10. Since the PCB board needs to be welded on both sides, the first welding mechanism 5 in this embodiment is used to implement welding operations on one side.

[0043] When the USB connector welding device adopting the above structure is working, the USB shell is sequentially input into the first loading platform 20 from the second opening 201 on the first loading platform 20, and then the USB shell is pushed to the first opening 200 one by one via the pushing member 21. Then, the USB shell is sent into the first chute 10 by the driving mechanism 3, and moves step by step in the first chute 10. At the same time, the transfer mechanism 40 drives the suction head 41 to move, suck up the PCB board matched with the USB shell and place it on the USB shell located in the first chute 10. When the USB shell moves to the position of the first welding mechanism 5, the first welding mechanism 5 acts to perform welding operation on the USB shell located below it, so as to weld the USB and the PCB board together. After welding, it flows out from the other end of the first chute 10. It can be seen that the USB connector welding device with the above structure, through the configuration of the mechanized structure, can not only realize automated welding operations, but also automatically complete the loading of USB shells and PCB boards. The entire operation process does not require manual supervision and realizes fully automated operations, thereby reducing manpower consumption, improving the assembly efficiency of USB connectors, and the quality is controllable.

[0044] like Figure 8 As shown, the push member 21 configured for the first loading mechanism 2 includes a push rod 210 and a material picking frame 211 arranged at the free end of the push rod 210. The material picking frame 211 is used to pick up the USB shell. The push rod 210 can drive the material picking frame 211 to move back and forth between the first opening 200 and the second opening 201. In this embodiment, through the setting of the material picking frame 211, the USB shell is pushed to the first opening 200 in a fixed posture, avoiding the USB shell from being offset during being pushed to the first opening 200. When the push rod 210 drives the material picking frame 211 to be opposite to the second opening 201, the USB shell enters the material picking frame 211 through the second opening 201, and then as the push rod 210 moves toward the first opening 200, the material picking frame 211 is moved to the first opening 200. At this time, the USB shell located in the material picking frame 211 is directly opposite to the first slide 10.

[0045] like Figure 4 As shown, in order to prevent the USB shell from falling off during movement, a cover plate 12 is further provided on the first slide groove 10, and when the USB shell is located in the first slide groove 10, the welding part at one end of the USB shell is located outside the cover plate 12, thereby not affecting the welding operation of the first welding mechanism 5.

[0046] Furthermore, if Figures 2 to 7 As shown, the driving mechanism 3 includes a driver 30 and a push-pull rod 31 connected to the driver 30. A first push-pull channel 13 is provided in the frame 1, and a second push-pull channel 202 opposite to the first push-pull channel 13 is provided on the first loading platform 20, so that the push-pull rod 31 can enter the first push-pull channel 13 from the second push-pull channel 202, and the push-pull rod 31 can perform telescopic push-pull motion in the first push-pull channel 13 and the second push-pull channel 202 driven by the driver 30. A first through groove 14 connected to the first push-pull channel 13 is provided on the bottom wall of the first slide 10, and a second through groove 203 connected to the second push-pull channel 202 and opposite to the first through groove 14 is provided on the first loading platform 20, that is, the central axes of the first through groove 14 and the second through groove 203 are located on the same straight line. The push-pull rod 31 is provided with a plurality of teeth 32 that can extend into the first slide groove 10. The plurality of teeth 32 extend from the first loading platform 20 to the first slide groove 10. The spacing between two teeth 32 is equivalent to the width of the USB shell. When the push-pull rod 31 is pulled back, the teeth 32 can rotate downward under the blocking force of the USB shell to avoid the USB shell. In addition, if Figure 8 In order to allow the tooth piece 32 to pass through the material taking frame 211, a third through slot 212 is provided on the material taking frame 211 for the tooth piece 32 to pass through.

[0047] The working principle of the driving mechanism 3 in the above embodiment is:

[0048] For the USB shell of the first opening portion 200 located on the first loading platform 20, first, the driver 30 drives the push-pull rod 31 to pull back (move backward), and the tooth piece 32 located at the front end of the USB shell enters the second through groove 203 under the blocking force of the USB shell, thereby moving from the bottom of the USB shell to the rear end of the USB shell, and then the tooth piece 32 extends out of the second through groove 203 again and enters the second slide groove 11, and then the driver 30 drives the push-pull rod 31 to move forward, and the tooth piece 32 pushes the USB shell to move one position and enter the first slide groove 10.

[0049] For the USB housing located in the first slide groove 10, when the push-pull rod 31 is pulled back and moved backward, the tooth piece 32 located in the first slide groove 10 rotates and moves downward under the blocking force of the USB housing into the first through groove 14, thereby passing from the bottom of the USB housing to the rear end of the current USB housing, and then when the push-pull rod 31 moves forward, the current USB housing is pushed forward by a displacement. It should also be noted that for the position without the tooth piece 32 at the front end, the USB housing at the rear is pushed forward by the USB housing at the rear.

[0050] Specifically, Figure 6 and Figure 7As shown, the tooth plate 32 includes a pivot portion 321 and a tooth portion 320. The tooth plate 32 is pivotally connected to the push-pull rod 31 through the pivot portion 321, so that the tooth portion 320 can be rotatably moved up and down with the pivot portion 321 as the rotation axis. The push-pull rod 31 is provided with a receiving groove 310 opposite to the tooth portion 320, and a first elastic member 311 is provided in the receiving groove 310, and the top of the first elastic member 311 abuts against the bottom end of the tooth portion 320; a slope 322 is provided on the side of the tooth portion 320 that is away from the moving direction of the USB shell. When the push-pull rod 31 is pulled back, the USB shell provides a rotational torque to the tooth portion 320 of the tooth plate 32 through the slope 322, thereby pressing the tooth portion 320 into the first through groove 14, and when the push-pull rod 31 moves forward, the rotational torque of the tooth portion 320 of the tooth plate 32 is zero, thereby pushing the USB shell forward.

[0051] like Fig.10 As shown, in order to prevent the USB shell from deviating left and right during the movement in the first slide groove 10, a plurality of first limiting grooves 140 connected to the first slide groove 10 are provided on the side wall of the frame 1 along the extension direction of the first slide groove 10, and a first limiting column 141 is provided in the first limiting groove 140. One end of the first limiting column 141 is connected to a first base 143 provided on the side wall of the first slide groove 10 through a second elastic member 142, and the other end of the first limiting column 141 can abut against the USB shell located in the first slide groove 10. In this embodiment, when the USB shell enters the first slide groove 10, the side wall of the USB shell elastically abuts against the first limiting column 141, so that the USB shell moves close to the groove wall on the other side to prevent deviation during the movement.

[0052] Furthermore, if Fig.10 and Fig.11 As shown, in order to avoid the USB shell from moving during the welding process and affecting the welding quality, the welding device in this embodiment also includes a positioning plate 15 installed on the cover plate 12. The positioning plate 15 includes a plate body 150. One side of the plate body 150 is provided with a plurality of positioning posts 151 extending along the first slide groove 10. The spacing between two adjacent positioning posts 151 is equivalent to the width of the USB shell. The other side of the plate body 150 is provided with a plurality of upper slots 152. The cover plate 12 is provided with a narrow and long through slot 154 extending along the extension direction of the first slide groove 10. One side of the through slot 154 is provided with a plurality of lower slots 153 extending along the through slot 154. A third elastic member (not shown) is provided between the upper slot 152 and the lower slot 153. The positioning posts 151 on the plate body 150 can enter the first slide groove 10 through the through slot 154. The third elastic member provides the plate body 150 with a constant upward movement elastic force so that the positioning posts 151 avoid the USB shell. In addition, please refer to Fig. 9The welding device in this embodiment further includes a pressing plate 155 that can move up and down. The pressing plate 155 is used to press down the positioning plate 15 so that the front and rear positioning posts 151 can clamp the USB shell below it in the current position. In this embodiment, under the action of the third elastic member, when the positioning plate 15 is not subjected to the pressure of the pressing plate 155, the positioning post 151 is located above the USB shell and will not affect the movement of the USB shell. When the first welding mechanism 5 performs the welding operation, the pressing plate 155 moves down and applies a certain downward pressure to the positioning plate 15, so that the positioning post 151 moves down, and the USB shell is clamped between the two adjacent positioning posts 151, thereby realizing the positioning of the USB shell. In this embodiment, the pressure plate 155 is arranged on the transfer mechanism 40, and the transfer mechanism 40 includes a lifting mechanism 400 and a translation mechanism 401. The lifting mechanism 400 is installed on the translation mechanism 401, and the suction head 41 is installed on the lifting mechanism 400. The pressure plate 155 can be set on a mounting frame for installing the suction head 41. When the transfer mechanism 40 places the PCB board on the USB shell, the suction head 41 moves down, and the pressure plate 155 located on the mounting frame presses down the positioning plate 15. After the welding operation of the first welding mechanism 5 is completed, the lifting mechanism 400 drives the suction head 41 to move up, so that the pressure plate 155 is separated from the positioning plate 15, and the positioning plate 15 is reset.

[0053] In addition, in the above embodiment, in order to prevent the positioning plate 15 from falling off from the through slot 154 , a limit card 156 is provided on the cover plate 12 at both ends of the through slot 154 , and the limit card 156 is used to limit the upward movement distance of the positioning plate 15 .

[0054] Please refer again Fig.10 In order to prevent the USB housing from moving too fast in the first slide groove 10, a second limiting groove 160 is further provided at the front end of the cover plate 12. A second limiting column 161 communicating with the first slide groove 10 is provided in the second limiting groove 160. The upper end of the second limiting column 161 is connected to a second base 163 installed on the cover plate 12 through a fourth elastic member 162. The lower end of the second limiting column 161 can abut against the top wall of the USB housing located in the first slide groove 10. When the USB housing enters the first slide groove 10, the top wall of the USB housing abuts against the second limiting column 161. The second limiting column 161 provides a downward elastic pressure for the USB housing, thereby increasing the sliding friction between the USB housing and the bottom wall of the first slide groove 10, thereby preventing the USB housing from moving uncontrollably and quickly in the first slide groove 10.

[0055] like Figure 1 and Figure 4As shown, the second loading mechanism also includes a second loading platform 42, a loading trough 43, a conveying track 44, a side push mechanism 45 and a front push mechanism 46 arranged on one side of the frame 1. The second loading platform 42 is arranged on one side of the conveying track 44. The loading trough 43 is used to receive the PCB board, and the loading trough 43 is arranged on the second loading platform 42, and the bottom of the loading trough 43 is connected to the second loading platform 42. The side push mechanism 45 includes a side push rod 450 arranged at the bottom of the loading trough 43, and the side push rod 450 is used to push the PCB board located at the bottom of the loading trough 43 to the conveying track 44. The front push mechanism 46 includes a front push rod 460 arranged at the rear end of the conveying track 44, and the front push rod 460 is used to push the PCB board pushed from the second loading platform 42 to the conveying track 44 forward by a certain distance. The working process of the second loading mechanism in this embodiment is as follows: multiple PCB boards are stacked and placed in the loading trough 43, first the side push mechanism 45 is started, and the PCB board at the bottom layer in the loading trough 43 is pushed to the conveying track 44 docking with the second loading platform 42 through the side push rod 450, then the front push mechanism 46 is started, and the PCB board pushed onto the second loading platform 42 is pushed forward by a displacement through the front push rod 460, and the cycle is repeated in sequence, and the PCB board in the front is continuously pushed forward by the PCB behind until it is within the working range of the transfer mechanism 40.

[0056] The welding device disclosed in the above embodiment can realize welding on one side (such as the front side) of the PCB board. In order to realize automatic welding on the other side (such as the back side) of the PCB board through the welding device at the same time, another preferred embodiment of the USB connector welding device of the present invention is provided. Figure 1 and Figure 4 The frame 1 is also provided with a second chute 11 docking with the first chute 10, a flip plate 7 is provided between the second chute 11 and the first chute 10, and a transition groove (not shown) is provided in the flip plate 7, the two ends of which are docked with the first chute 10 and the second chute 11 respectively. The flip plate 7 is used to flip the USB shell received from the first chute 10 by 180 degrees and then transport it to the second chute 11. A second welding mechanism 6 is provided above the second chute 11, and the second welding mechanism 6 is used to perform welding operations on the corresponding parts of the USB shell PCB board located in the second chute 11. When the front side of the PCB board is welded on the USB shell, the USB shell enters the transition groove from the first chute 10, and then the flip plate 7 flips 180 degrees, thereby flipping the USB and the PCB board together by 180 degrees, so that the back side of the PCB board faces upward, and then, under the push of the rear USB shell, the flipped USB shell enters the second chute 11 from the transition groove, and then the second welding mechanism 6 moves down to perform welding operations on the back side of the PCB board.

[0057] In summary, if Figures 1 to 11The detailed working process of the USB connector welding device disclosed in the above embodiment is as follows: first, the USB shell is transported to the first loading platform 20, and the USB shells are pushed one by one to the first opening 200 of the first loading platform 20 through the push rod 210 and the material picking frame 211, then the driving mechanism 3 is started, the USB shell is sent into the first slide 10 on the frame 1, and the PCB board is transported one by one to the position of the transfer mechanism 40 through the second loading mechanism, the transfer mechanism 40 is operated, and the PCB board is adsorbed and placed on the USB shell that enters the first slide 10 and is located below the first welding mechanism 5 through the suction head 41, and then the first welding mechanism 5 performs the welding operation to weld the front side of the PCB to the USB shell. Next, the USB shell is pushed into the transition groove of the flip plate 7, and then the USB shell is flipped 180° through the flipping movement of the flip plate 7, and then output to the second slide 11, and then the second welding mechanism 6 is started to perform the welding operation on the back side of the PCB board. After the welding is completed, the welded USB connector is output from the tail end of the second slide 11. It can be seen that the above-mentioned USB connector welding device can realize automatic loading, automatic welding and automatic flipping processes in the USB connector welding process, that is, it realizes the full automation operation of USB connector welding, reduces labor costs and improves work efficiency.

[0058] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
