[0044] Please refer to Figures 1-8 The present application is described in detail by the following examples:

[0045] An automatic integrated needle loading device for connector processing, comprising:

[0046] The feeding device 1 comprises a vibrating sorting machine 11 for sorting connectors, and the sorted connectors are sent to the pushing device 2 through a conveying device. The conveying device comprises a discharge chute 12, the top end of which is fixedly installed with a storage chute 13, the left end of which is provided with a feeding slot 14, the back of which is fixedly installed with a feeding cylinder 15, the piston rod of which is fixedly connected with the feeding slot 14, and the extension or shortening of the piston rod of the feeding cylinder 15 can drive the feeding slot 14 to move forward and backward.

[0047] The right end of the discharge chute 12 is fixedly connected with the discharge port of the vibrating sorting machine 11, which is used for sorting connectors, and the vibrating sorting machine 11 adopts a known vibrating sorting device. The connectors sorted by the vibrating sorting machine 11 can enter the discharge chute 12 in the same arrangement direction, and then enter the feeding slot 14 through the storage chute 13. The length of the feeding slot 14 should be the same as the length of a single connector, and the extension or retraction of the piston rod of the feeding cylinder 15 can drive the feeding slot 14 to move forward or backward, thereby driving the connectors to move forward or backward.

[0048] A blocking baffle 17 is welded to the right side of the back of the feeding slot 14.

[0049] When the feeding slot 14 moves forward, the blocking baffle 17 will block the left end of the storage chute 13 to prevent the connectors in the storage chute 13 from sliding out.

[0050] The pushing device 2 comprises a working slide 23, a pushing cylinder 27 arranged at the right side of the working slide 23, and used for pushing the plug-in connector into the working slide 23. A first working table 21 is fixedly arranged below the working slide 23. A plug-in connector sliding groove 25 is arranged in the working slide 23, and a working gap 26 is arranged at the front of the plug-in connector sliding groove 25. A second working table 22 is welded at the front of the first working table 21. A limiting baffle 24 is welded at the back right end of the working slide 23. The pushing cylinder 27 is fixedly arranged at the right end of the first working table 21. The shaft center of the pushing cylinder 27 and the shaft center of the plug-in connector sliding groove 25 are located on the same straight line.

[0051] The feeding groove 14 is driven by the feeding cylinder 15 to move forward, and stops moving when it is flush with the working slide 23. The piston rod of the pushing cylinder 27 is controlled to extend, so as to push the plug-in connector in the feeding groove 14 into the plug-in connector sliding groove 25. Then, the piston rod of the pushing cylinder 27 is controlled to retract, and the feeding cylinder 15 is controlled to drive the feeding groove 14 to retreat to the original position. Thus, automatic feeding is realized. The feeding cylinder 15 is fixedly arranged at the right rear side of the first working table 21 through a feeding support 16.

[0052] Further comprising:

[0053] The preloading needle device 3 is arranged at the front side of the working slide 23, and comprises a needle arranging device. A pushing needle baffle 35 is arranged below the needle arranging device, and is driven by a pushing needle cylinder 37 to move the plug-in needle forward and backward. The preloading needle device 3 is arranged on the top surface of the second working table 22. The needle arranging device comprises a needle storage box 31. A sorting bin 32 is welded below the needle storage box 31. A sorting partition 33 is welded in the sorting bin 32. A guiding baffle 34 is fixedly arranged at the outer bottom side of the sorting bin 32. The pushing needle baffle 35 is arranged below the guiding baffle 34.

[0054] The needle storage box 31 is used for containing the plug-in needle. The plug-in needle slides downward under the action of gravity, is blocked by the sorting partition 33, and enters the gap between the sorting partitions 33. The gap between the sorting partitions 33 should be just the width of a single plug-in needle. The length of the sorting partition 33 should be equal to the length of a single plug-in needle.

[0055] A pushing needle groove 36 is arranged at the front top surface of the pushing needle baffle 35, and the length of the pushing needle groove 36 is less than the length of the sorting bin 32. A pushing needle platform 38 is arranged below the guiding baffle 34. A first lifting cylinder 39 is fixedly arranged at the bottom surface of the pushing needle platform 38. The pushing needle cylinder 37 is fixedly arranged at the rear top surface of the pushing needle platform 38. The top end of the piston rod of the pushing needle cylinder 37 is fixedly connected with the tail end of the guiding baffle 34.

[0056] The guide baffle plate 34 is fixedly connected with the push pin platform 38 by screws. The extension or retraction of the piston rod of the first lifting cylinder 39 can control the rising or falling of the push pin platform 38, so as to align the push pin slot 36 with the jack plug hole. The depth of the push pin slot 36 should be the same as the thickness of the pin, and the length of the push pin slot 36 should be greater than half of the control sorting bin 32. The extension or retraction of the piston rod of the push pin cylinder 37 can control the forward or backward movement of the push pin baffle plate 35. When the push pin baffle plate 35 moves to the last position, the pin falls into the push pin slot 36 from the gap between the sorting partitions 33. The extension of the piston rod of the push pin cylinder 37 drives the push pin baffle plate 35 to move forward, so as to drive the pin to move forward until the front end of the push pin baffle plate 35 is flush with the front end of the guide baffle plate 34. Since the length of the push pin slot 36 is less than the length of the sorting bin 32, that is, the push pin slot 36 is less than the length of the pin, the pin exceeding the push pin slot 36 will be inserted into the jack plug. At this time, the piston rod of the push pin cylinder 37 is retracted, and the pin will be left in the jack plug, realizing the pre-assembly of the pin.

[0057] The compacting device 4 includes a top pin plate driven by a compacting cylinder 46 and capable of moving forward and backward for pressing the pin and compacting. The compacting device 4 is installed on the top surface of the second workbench 22. The top pin plate includes a clamping bottom plate 41 and a clamping top plate 42. The clamping bottom plate 41 and the clamping top plate 42 are provided with clamping pin slots 43 on the front side in contact with each other. The push pin cylinder 37 is located behind the top pin plate, and the piston rod of the push pin cylinder 37 is fixedly connected with the clamping bottom plate 41.

[0058] The clamping top plate 42 is fixedly installed on the top surface of the clamping bottom plate 41 by screws. The clamping pin slots 43 of the clamping top plate 42 should correspond to the clamping pin slots 43 of the clamping bottom plate 41 one by one. The depth of the clamping pin slot 43 should be half of the thickness of the pin, and the length of the clamping pin slot 43 should be the designed reserved length of the pin. The extension or retraction of the piston rod of the push pin cylinder 37 can control the forward and backward movement of the clamping bottom plate 41, thereby driving the clamping top plate 42 to move forward and backward.

[0059] The clamping bottom plate 41 is provided below with a support platform 45, and the clamping top plate 42 is slidably installed above the support platform 45 by a sliding fixing frame 44. The bottom of the support platform 45 is fixedly installed with a second lifting cylinder 47. The push pin cylinder 37 is fixedly installed on the top surface of the support platform 45 at the rear.

[0060] The extension or retraction of the piston rod of the second lifting cylinder 47 can control the rising or falling of the support platform 45, thereby driving the top pin plate to rise or fall, and further aligning the clamping pin slot 43 with the pin preassembled on the jack plug.

[0061] The pre-bending assembly 5 includes a pre-bending block 51 driven by a pre-bending cylinder 55 and capable of moving forward and backward, the pre-bending block 51 is provided with a bending inclined surface 52 capable of abutting against the contact pin and bending the contact pin to a certain angle, and the pre-bending assembly 5 is installed on the top surface of the second workbench 22. A bending platform 53 is arranged below the pre-bending block 51, the pre-bending block 51 is slidably connected with the bending platform 53 through a bending guide support 54, the pre-bending cylinder 55 is installed at the rear of the pre-bending block 51 and on the top surface of the bending platform 53, and the third lifting cylinder 56 is fixedly installed on the bottom surface of the bending platform 53.

[0062] By controlling the extension or retraction of the piston rod of the third lifting cylinder 56, the rising or falling of the bending platform 53 can be controlled, thereby driving the pre-bending block 51 to rise or fall, and further aligning the lower edge of the bending inclined surface 52 of the pre-bending block 51 with the lower edge of the contact pin. By controlling the extension or retraction of the piston rod of the pre-bending cylinder 55, the pre-bending block 51 can be driven to move forward and backward, when the pre-bending block 51 moves forward, the bending inclined surface 52 will abut against the contact pin, so that the contact pin is bent along the slope of the bending inclined surface 52. The bending angle of the contact pin is the same as the slope of the bending inclined surface 52, and because of the existence of the bending inclined surface 52, the contact pin is prevented from deforming in other directions when being bent, or being broken due to excessive bending at one time.

[0063] The bending device 6 includes a horizontal bending block 61 and a vertical bending plate 66, which cooperate with each other to bend the contact pin by 180 degrees. The bending device 6 is installed on the top surface of the second workbench 22. A horizontal bending platform 63 is arranged below the horizontal bending block 61, the horizontal bending platform 63 is fixedly installed with a horizontal bending cylinder 64, and the piston rod of the horizontal bending cylinder 64 is fixedly connected with the tail end of the horizontal bending platform 63. The horizontal bending block 61 is slidably connected with the horizontal bending platform 63 through a horizontal guide support 62. The fourth lifting cylinder 65 is fixedly installed on the bottom of the horizontal bending platform 63.

[0064] By controlling the extension or retraction of the piston rod of the fourth lifting cylinder 65, the rising or falling of the horizontal bending platform 63 can be controlled, thereby driving the horizontal bending block 61 to rise or fall, and further aligning the upper edge of the horizontal bending block 61 with the part of the contact pin to be bent. By controlling the extension or retraction of the piston rod of the horizontal bending cylinder 64, the horizontal bending block 61 can be driven to move forward and backward. Since the contact pin has been bent to a certain angle after passing through the pre-bending assembly 5, when the horizontal bending block 61 moves forward, it will abut against the middle part of the contact pin and drive the contact pin to move towards the connector, so that the contact pin is bent upward by 90 degrees.

[0065] The vertical bending plate 66 is provided with a vertical bending frame 68 behind it, which is fixedly installed on the top surface of the working slide 23 by screws. The vertical bending frame 68 is fixedly installed with a vertical bending cylinder 69 on the upper part of the front side surface of the vertical bending frame 68. The piston rod of the vertical bending cylinder 69 is fixedly connected with the top end of the vertical bending plate 66. The vertical bending plate 66 is slidably connected with the vertical bending frame 68 through a vertical guide frame 67.

[0066] The extension or retraction of the piston rod of the vertical bending cylinder 69 can control the rising or falling of the vertical bending plate 66. When the vertical bending plate 66 falls, it will push against the top end of the pin and drive the pin to bend downward. Since the upper edge of the horizontal bending block 61 pushes against the middle part of the pin, the pin will bend downward by 90 degrees with the upper edge of the horizontal bending block 61 as the axis. The horizontal bending block 61 and the vertical bending plate 66 can cooperate to bend the pin by 180 degrees.

[0067] When the operator uses the device, the plug-in part is placed in the vibrating material sorting machine 11, and the pin is placed in the pin storage box 31. After being sorted by the vibrating material sorting machine 11, the plug-in part enters the discharge chute 12 in the same arrangement direction and finally enters the feeding groove 14. The limiting baffle 24 will block the plug-in part to prevent it from sliding out of the left end of the feeding groove 14.

[0068] The extension of the piston rod of the pushing cylinder 27 drives the feeding groove 14 to be flush with the working slide 23. The extension of the piston rod of the pushing cylinder 27 pushes the plug-in part into the plug-in part sliding groove 25. Then the retraction of the piston rod of the pushing cylinder 27 and the retraction of the piston rod of the feeding cylinder 15 drive the feeding groove 14 to return to the original position.

[0069] The above steps are repeated to realize automatic feeding of the plug-in part. After the pushing cylinder 27 pushes the second plug-in part into the plug-in part sliding groove 25, it will push against the first plug-in part to move.

[0070] The extension or retraction of the piston rod of the first lifting cylinder 39 can control the rising or falling of the pin pushing platform 38, so as to align the pin pushing groove 36 with the plug-in hole. The retraction of the piston rod of the pin pushing cylinder 37 controls the rear movement of the pin pushing baffle 35, and the pin falls into the pin pushing groove 36 from the gap between the sorting partitions 33. The extension of the piston rod of the pin pushing cylinder 37 drives the pin pushing baffle 35 to move forward, thereby driving the pin to move forward until the front end of the pin pushing baffle 35 is flush with the front end of the guide baffle 34. At this time, the pin in the pin pushing groove 36 will be inserted into the plug-in part. Then the retraction of the piston rod of the pin pushing cylinder 37 will leave the pin in the plug-in part, realizing the pre-assembly of the pin. When the piston rod of the pin pushing cylinder 37 is retracted to the shortest, a new plug-in part is pushed by the pushing cylinder 27, and the plug-in part that has completed the pre-assembly of the pin will be squeezed to the compaction device 4.

[0071] By controlling the piston rod of the second lifting cylinder 47 to extend or retract, the needle slot 43 is aligned with the needle on the inserted piece. By controlling the piston rod of the pushing cylinder 37 to extend, the clamping bottom plate 41 moves forward and backward, thereby driving the clamping top plate 42 to move forward. The needle is first inserted into the needle slot 43, clamped by the ejector plate, and then moves forward with the ejector plate until the remaining part is completely inserted into the inserted piece, and the compaction is completed. Then, by controlling the piston rod of the pushing cylinder 37 to retract, the ejector plate is retracted. At this time, a new inserted piece is pushed by the pushing cylinder 27, and the inserted piece with the needle compacted is squeezed to the pre-bending assembly 5.

[0072] By controlling the piston rod of the third lifting cylinder 56 to extend or retract, the lower edge of the bending slope 52 of the pre-bending block 51 is aligned with the lower edge of the needle. By controlling the piston rod of the pre-bending cylinder 55 to extend, the pre-bending block 51 is driven to move forward, and the bending slope 52 abuts against the needle, so that the needle is bent along the slope of the bending slope 52. Then, by controlling the piston rod of the pre-bending cylinder 55 to retract, the pre-bending block 51 is driven to move backward. At this time, a new inserted piece is pushed by the pushing cylinder 27, and the inserted piece with the needle pre-bent is squeezed to the bending device 6.

[0073] By controlling the piston rod of the fourth lifting cylinder 65 to extend or retract, the upper edge of the horizontal bending block 61 is aligned with the part of the needle that needs to be bent. By controlling the piston rod of the horizontal bending cylinder 64 to extend, the horizontal bending block 61 is driven to move forward and abut against the middle part of the needle, thereby driving the needle to move towards the inserted piece, so that the needle is bent upward by 90 degrees. At the same time, by controlling the piston rod of the vertical bending cylinder 69 to extend, the vertical bending plate 66 is driven to move downward and abut against the top end of the needle, thereby driving the needle to be bent downward by 90 degrees with the upper edge of the horizontal bending block 61 as the axis. After the bending is completed, the horizontal bending block 61 and the vertical bending plate 66 are controlled to return to the original position. At this time, a new inserted piece is pushed by the pushing cylinder 27, and the inserted piece with the needle bent is squeezed out of the inserted piece sliding groove 25.
