Abstract
Description
Technical Field
[0001] This invention relates to the field of needle suction equipment technology, and in particular to a needle suction device for insulating components. Background Technology
[0002] Twisted needles are used in my country's aerospace field as core components of spacecraft. They are shaped like a braid and as thin as a hair. They are made of 10 strands of copper alloy wire and are the main connector accessories in high-end electronic components. In order to improve the processing effect of twisted needles, needle suction devices are used to pick up the twisted needles and put them into the processing equipment.
[0003] However, existing needle suction devices have the following problems: The main working principle of existing needle suction devices is to draw a vacuum to adsorb the twisted needle onto the suction device. However, due to mechanical failures or vision system malfunctions, existing needle suction devices may place the twisted needle incorrectly. This will cause the two sides of the twisted needle to contact the protrusions on the placement surface. As a result, the protrusions will impact the needle of the suction device, which will cause the needle to bend or even break. This will also affect the processing efficiency of the twisted needle and the stability of the needle suction device during long-term operation. Summary of the Invention
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an insulating component needle suction device that can solve the problem that when the position of the twisted needle is incorrect, the needle will bend or even break, which also affects the processing efficiency of the twisted needle and the stability of the needle suction device during long-term operation.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an insulating component needle suction device, comprising an outer housing, wherein an active cavity is provided inside the outer housing, and a sliding groove extending out of the lower surface of the outer housing is provided on the bottom wall of the active cavity. A suction nozzle pipe extending into the active cavity on its upper side and out of the lower side of the outer housing on its lower side is slidably connected in the sliding groove. A sliding hole communicating with the lower surface of the suction nozzle pipe is provided on the lower surface of the suction nozzle pipe. A mounting slide post extending out of the lower surface of the suction nozzle pipe on its lower side is slidably connected inside the suction nozzle pipe. A needle is fixedly provided on the lower surface of the mounting slide post, extending out of the upper surface of the mounting slide post and into the suction nozzle pipe. A fixing post is fixedly connected to the top wall of the suction nozzle pipe. One end of the needle located in the suction nozzle pipe slides through into the fixing post. A limiting head is fixedly sleeved on the outer surface of the end of the needle located in the fixing post. A support spring movably sleeved on the outer surface of the needle is fixedly connected between the mounting slide post and the fixing post. A proximity sensor is provided on the side surface of the fixing post facing the mounting slide post.
[0006] Preferably, a first sealing ring is fixedly sleeved on the outer surface of one end of the suction pipe located in the sliding groove, which contacts the inner wall of the sliding groove.
[0007] Preferably, a movable push block is fixedly sleeved on the outer surface of one end of the suction pipe located in the movable cavity, which is slidably connected to the inner wall of the movable cavity, and a second sealing ring is fixedly sleeved on the outer surface of the movable push block, which contacts the inner wall of the movable cavity.
[0008] Preferably, the outer surface of the outer housing has two mounting holes, both of which communicate with the movable cavity. The two mounting holes are located on the upper and lower sides of the movable push block, respectively. A lower air pipe connector and an upper air pipe connector are fixedly connected in the two mounting holes, and both the upper air pipe connector and the lower air pipe connector extend out of the outer surface of the outer housing.
[0009] Preferably, the top wall of the active cavity is fixedly connected to an installation block, and an external vacuum tube is provided on the upper side of the outer shell, with its lower end sliding through the lower surface of the installation block and finally extending into the active cavity. One end of the external vacuum tube located in the active cavity is fixedly inserted into the suction nozzle pipe.
[0010] Preferably, one end of the external vacuum tube is fixedly inserted into the fixed column inside the suction nozzle pipe, and a corrugated pipe is fixedly connected between the limiting head and the external vacuum tube.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] (1) When the needle suction device of the insulating component is not positioned correctly when placing the twisted needle, the twisted needle will contact the protruding part of the placement surface and exert an upward thrust on the needle, thereby causing the mounting slide to move upward synchronously. At the same time, the support spring is compressed under force, the needle pushes the limiting head upward, and the proximity sensor detects that the mounting slide is gradually approaching. Therefore, the proximity sensor transmits a signal to the external alarm, causing the external alarm to sound an alarm and remind the staff that there is an abnormal placement. This method effectively avoids the problem of the needle bending or even breaking when the twisted needle is not positioned correctly during placement, thus further ensuring the stability of the needle suction device during long-term operation.

[0020] Please see Figure 1-3 The present invention provides a technical solution: an insulating component suction needle device, including an outer housing 1, an active cavity 3 inside the outer housing 1, a sliding groove 4 extending out of the lower surface of the outer housing 1 on the bottom wall of the active cavity 3, a suction pipe 2 extending into the active cavity 3 on the upper side and out of the lower side of the outer housing 1 on the lower side slidably connected in the sliding groove 4, and a first sealing ring 5 fixedly sleeved on the outer surface of one end of the suction pipe 2 located in the sliding groove 4, which contacts the inner wall of the sliding groove 4, thereby increasing the sealing between the suction pipe 2 and the sliding groove 4.
[0021] Furthermore, a mounting block 8 is fixedly connected to the top wall of the movable cavity 3. An external vacuum tube 9 is provided on the upper side of the outer shell 1, with its lower end sliding through the lower surface of the mounting block 8 and finally extending into the movable cavity 3. One end of the external vacuum tube 9 located in the movable cavity 3 is fixedly inserted into the suction nozzle pipe 2. A movable push block 6, which is slidably connected to the inner wall of the movable cavity 3, is fixedly sleeved on the outer surface of the end of the suction nozzle pipe 2 located in the movable cavity 3. A second sealing ring 7, which contacts the inner wall of the movable cavity 3, is fixedly sleeved on the outer surface of the movable push block 6. Two mounting holes 10, both communicating with the movable cavity 3, are opened on the outer surface of the outer shell 1. The two mounting holes 10 are located on the upper and lower sides of the movable push block 6, respectively. A lower air pipe connector 11 and an upper air pipe connector 12 are fixedly connected to the two mounting holes 10, respectively. The upper air pipe connector 12 and the lower air pipe connector... Both 11 extend beyond the outer surface of the outer housing 1. In use, the lower air pipe connector 11 and the upper air pipe connector 12 are respectively connected to two air supply pipes at their ends outside the outer housing 1. Both air supply pipes are connected to the air supply equipment and are equipped with two valves. In this way, the air supply equipment can deliver gas to the lower air pipe connector 11 and the upper air pipe connector 12 respectively. When gas is delivered to the lower air pipe connector 11, the pressure on the lower side of the movable push block 6 increases, thus pushing the movable push block 6 to move upward. At the same time, the suction pipe 2 moves upward. When gas is delivered to the upper air pipe connector 12, the pressure on the upper side of the movable push block 6 increases, thus pushing the movable push block 6 to move downward. At the same time, the suction pipe 2 moves downward, realizing the upward or downward movement of the suction pipe 2, thereby achieving the lifting and placement of the twist needle.
[0022] Please see Figure 4-5 The lower surface of the suction pipe 2 has a sliding hole communicating with its interior. A mounting slide post 14, extending from the lower surface of the suction pipe 2, is slidably connected inside the suction pipe 2. A suction needle 13, with its upper end fixedly extending through the upper surface of the mounting slide post 14 and into the suction pipe 2, is provided on the lower surface of the mounting slide post 14. A fixing post 15 is fixedly connected to the top wall of the suction pipe 2. The fixing post 15 is hollow inside. One end of an external vacuum tube 9 located inside the suction pipe 2 is fixedly inserted into the fixing post 15. One end of the suction needle 13 located inside the suction pipe 2 slides through the fixing post 15. Inside the column 15, a limiting head 18 is fixedly sleeved on the outer surface of one end of the suction needle 13 located inside the fixed column 15. A bellows 19 is fixedly connected between the limiting head 18 and the external vacuum tube 9. At the same time, the end of the external vacuum tube 9 located outside the outer shell 1 is connected to the vacuum pump through the vacuum tube. Therefore, when the vacuum pump is started, the air inside the suction needle 13 can be absorbed through the external vacuum tube 9. Therefore, when the lower end of the suction needle 13 contacts the surface of the twisted needle, the air inside the suction needle 13 is drawn out and is in a negative pressure state. Therefore, the twisted needle is adsorbed on the suction needle 13 under the action of external pressure.
[0023] Furthermore, a support spring 16 is fixedly connected between the mounting slide 14 and the fixed column 15, and is movably sleeved on the outer surface of the suction needle 13. A proximity sensor 17 is provided on the side of the fixed column 15 facing the mounting slide 14. The proximity sensor 17 is connected to an external alarm device via a communication link. Therefore, when the suction needle is placed incorrectly, the twisted needle will contact the protruding part of the placement surface and exert an upward thrust on the suction needle 13, causing the mounting slide 14 to move upward synchronously. At the same time, the support spring 16 contracts under force, and the suction needle 13 pushes the limiting head 18 upward. The proximity sensor 17 detects that the mounting slide 14 is gradually approaching, so the proximity sensor 17 transmits a signal to the external alarm, causing the external alarm to sound an alarm and alert the staff that there is an abnormal placement. In this way, the problem of the suction needle 13 bending or even breaking when the twisted needle is incorrectly placed is effectively avoided, thus further ensuring the stability of the suction needle device during long-term operation.
[0024] In this design, the suction force required for the suction needle 13 to adsorb the twisted needle is relatively small. At the same time, a support spring 16 is provided between the mounting slide 14 and the fixed column 15, so there will be no problem of the mounting slide 14 shifting upward when adsorbing the twisted needle.
[0025] Working principle: When the device is in use, gas can be supplied to the lower gas pipe connector 11 and the upper gas pipe connector 12 through the gas supply equipment. When gas is supplied to the lower gas pipe connector 11, the pressure on the lower side of the movable push block 6 increases, thus pushing the movable push block 6 to move upward. At the same time, the suction pipe 2 moves upward. When gas is supplied to the upper gas pipe connector 12, the pressure on the upper side of the movable push block 6 increases, thus pushing the movable push block 6 to move downward. At the same time, the suction pipe 2 moves downward. This allows the suction pipe 2 to move upward or downward, thereby lifting and placing the twisted needle.
[0026] When the needle suction device is mispositioned when placing the twisted needle, the twisted needle will contact the protrusion of the placement surface and exert an upward thrust on the needle suction 13. This causes the mounting slide 14 to move upward synchronously, while the support spring 16 contracts under force. The needle suction 13 pushes the limiting head 18 upward, and the proximity sensor 17 detects that the mounting slide 14 is gradually approaching. Therefore, the proximity sensor 17 transmits a signal to the external alarm, causing the external alarm to sound an alarm and alert the staff that there is an abnormal placement.
