[0047] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0048] like Figure 1 and Figure 2 As shown, an automatic connector insertion mechanism based on a narrow space is used to insert a connector 9 on a base 10, and a socket 1001 for inserting the connector 9 is provided on the base 10;

[0049] The automatic insertion mechanism includes a platform, on which a conveyor line component 1, an insertion component 2, a lifting and positioning component 3, a displacement component 4, an upper visual component 5, a lower visual component 6 and a detection component 7 are installed:

[0050] The conveyor line assembly 1 is a roller chain conveyor line, which extends along the X-axis direction and is used to convey the base 10;

[0051] The plug-in assembly 2 includes a suction unit for sucking the connector 9 from the silo 8 and a pressing unit for pressing the sucked connector 9 into the plug hole 1001;

[0052] The lifting and positioning assembly 3 is used to lift the base 10 on the conveyor line assembly 1 for the press-fitting unit to perform the insertion operation, so as to avoid the base 10 moving with the conveyor line assembly 1 during the insertion operation, resulting in insertion errors;

[0053] The displacement component 4 is used to drive the insertion component 2 to move in three-dimensional directions;

[0054] The upper visual component 5 is used to identify and locate the socket 1001 on the base 10, and is located on the plug-in component 2;

[0055] The lower visual component 6 is used to identify and locate the connector 9 sucked by the adsorption unit, and is located on the platform and on the running track of the plug-in component 2;

[0056] The detection component 7 is used to detect the connector 9 after the insertion is completed;

[0057] During operation, first, the jacking and positioning component 3 is used to position and lift the base 10 on the conveyor line component 1, and the displacement component 4 drives the insertion component 2 to the position of the silo 8. After the adsorption unit absorbs the connector 9, the displacement component 4 drives the insertion component 2 to move in the direction of the base 10. During the process, the lower visual component 6 visually identifies and locates the bottom of the connector 9 to check whether the petals are missing. When the insertion component 2 moves above the base 10, the upper visual component 5 visually identifies and locates the socket 1001 on the base 10, and then the computer performs position compensation calculation to obtain the specific coordinate position of the connector 9 to be assembled and gives it to the displacement component 4. The displacement component 4 reaches the specified coordinate position according to the position feedback after the compensation calculation, and drives the pressing unit to press the connector 9 for insertion. After the insertion is completed, the detection component 7 performs detection, and the qualified products flow to the next station, realizing high-density and high-precision automatic insertion function in a small space.

[0058] In some examples, the plug-in assembly 2 further includes a mounting plate 201 connected to the output end of the displacement assembly 4, the adsorption unit includes a suction nozzle 202 slidably mounted on the mounting plate 201, a guide rail 206 is provided on the mounting plate 201, a sliding block 207 cooperating with the guide rail 206 is provided on the suction nozzle 202, and a limit block for limiting the sliding stroke of the sliding block 207 is provided on the guide rail 206, the press-fitting unit includes a pressing rod 203 fixedly mounted on the mounting plate 201 for pressing down the connector 9 to press it into the socket 1001, and the pressing rod 203 is slidably penetrated inside the suction nozzle 202, and the two are coaxially arranged;

[0059] Before the adsorption operation, the suction nozzle 202 slides to the bottom of the guide rail 206 under the action of its own gravity. At this time, the suction nozzle 202 has not extended out from the bottom of the pressure rod 203. The displacement component 4 drives the suction nozzle 202 to the silo 8, and the suction nozzle 202 generates negative pressure to absorb the connector 9. After the absorption is completed, the displacement component 4 drives the suction nozzle 202 to the position of the socket 1001 and drives the mounting plate 201 to move downward. The suction nozzle 202 and the pressure rod 203 thereon move downward synchronously, and the pressure rod 203 presses down the connector 9. When the suction nozzle 202 abuts against the base 10, the position of the suction nozzle 202 remains unchanged, and the pressure rod 203 continues to press down the connector 9 for the plug-in operation.

[0060] In some examples, a connecting plate 204 is provided between the mounting plate 201 and the output end of the displacement assembly 4, the mounting plate 201 is slidably connected to the connecting plate 204, and a dislocation cylinder 205 for driving the mounting plate 201 to move along the Z-axis direction is installed on the connecting plate 204, and there are a plurality of dislocation cylinders 205, mounting plates 201, suction nozzles 202 and pressure rods 203, and they correspond to each other one by one, such as Figure 3-Figure 7 As shown;

[0061] During the adsorption operation, each suction nozzle 202 absorbs a connector 9, and then the displacement component 4 drives the insertion component 2 to the position above one of the sockets 1001, and makes the socket 1001 face one of the connectors 9, and then the offset cylinder 205 corresponding to the connector 9 drives it to move down to stagger with other connectors 9 in height, and finally the displacement component 4 drives the insertion component 2 to move down, and the pressure rod 203 corresponding to the connector 9 presses it down to achieve insertion, at this time, one connector 9 is inserted, and the remaining connectors 9 have not yet contacted the base 10, and then the second, third and fourth connectors 9 are inserted according to the above process. Because the insertion positions of the connectors 9 are not distributed side by side and equidistantly, the offset cylinder 205 is set to achieve simultaneous absorption and gradual insertion of multiple connectors 9.

[0062] In some examples, the inner wall of the nozzle 202 is provided with a plurality of first air flow grooves 2021 spaced apart from each other along its circumference. Fig.11 As shown, the outer peripheral wall of the pressure rod 203 is provided with a plurality of second air flow grooves 2031 arranged at intervals along its circumference. Fig.10 As shown; when the top is vacuum-sucking, the first airflow groove 2021 and the second airflow groove 2031 can ensure that there is air flow inside the suction nozzle 202, driving the airflow to form a vacuum, generating a suction flow, so that the air around the bottom opening of the suction nozzle 202 is continuously sucked away, thereby reducing the pressure in the adsorption chamber to below the atmospheric pressure, forming a certain vacuum degree.

[0063] In some examples, the material bin 8 includes a storage rack 801 that is lifted and has multiple layers of storage trays 8011, a material retrieval rack 802 that is docked with the storage rack 801, a material retrieval component 803 for grabbing the storage tray 8011 in the storage rack 801 to the material retrieval rack 802, and a lifting and positioning component 804 for lifting the storage tray 8011 on the material retrieval rack 802 for the adsorption unit to perform adsorption operations, such as Fig. 9 As shown;

[0064] The multiple layers of material storage trays 8011 on the material storage rack 801 are arranged at longitudinal intervals. When the material storage rack 801 is raised or lowered, the material storage trays 8011 on it can be driven to be raised or lowered so that one layer of the material storage tray 8011 can be docked with the material picking rack 802. Then the material picking component 803 grabs the material storage tray 8011 and places it on the material picking rack 802. When it reaches the position of the lifting and positioning component 804, the lifting and positioning component 804 lifts it to separate it from the material picking rack 802 for absorption by the adsorption unit.

[0065] In some examples, the jacking positioning component 3 and the lifting positioning component 804 both include a lifting drive mechanism 301 and a jacking frame 302 connected to the output end of the lifting drive mechanism 301, the jacking frame 302 is provided with a positioning pin 303, the fixture 11 supported on the bottom of the base 10 is provided with a first positioning hole that cooperates with the positioning pin 303, and the storage tray 8011 is provided with a second positioning hole that cooperates with the positioning pin 303. The positioning pin 303 in the jacking positioning component 3 cooperates with the first positioning hole on the fixture 11 to achieve the positioning and lifting of the base 10, and the positioning pin 303 in the lifting positioning component 804 cooperates with the second positioning hole on the storage tray 8011 to achieve the positioning and lifting of the storage tray 8011. Figure 8 shown.

[0066] In some examples, the material picking component 803 includes a linear reciprocating drive mechanism 8031 ​​and a pneumatic clamping claw 8032 connected to the output end of the linear reciprocating drive mechanism 8031, and the pneumatic clamping claw 8032 includes two fingers that can move closer or farther away; the linear reciprocating drive mechanism 8031 ​​can drive the pneumatic clamping claw 8032 and the material storage tray 8011 clamped by the pneumatic clamping claw 8032 to move along the X-axis direction, so that it moves from the material storage rack 801 to the material picking rack 802.

[0067] In some examples, the displacement assembly 4 includes an X-axis drive mechanism 401 , an output end of the X-axis drive mechanism 401 is connected to a Y-axis drive mechanism 402 , an output end of the Y-axis drive mechanism 402 is connected to a Z-axis drive mechanism 403 , and an output end of the Z-axis drive mechanism 403 is connected to a connecting plate 204 .

[0068] In some examples, the detection component 7 is a 3D line scanning measuring instrument that is lifted and lowered on the plug-in component 2 and has an accuracy of ±0.01. It can check the XY axis position, Z axis height, and petal status of the connector 9 to ensure that it meets assembly requirements.

[0069] Working principle:

[0070] 1) When the base 10 on the conveyor line assembly 1 flows to the top of the lifting and positioning assembly 3, the lifting drive mechanism 301 drives the lifting frame 302 to lift, and the positioning pin 303 on the lifting frame 302 is inserted into the first positioning hole on the fixture 11, thereby driving the fixture 11 and the base 10 thereon to lift, so that the base 10 is separated from the conveyor line assembly 1;

[0071] 2) The displacement component 4 drives the insertion component 2 to the position of the silo 8, and the suction nozzle 202 generates negative pressure to suck the connector 9. After the suction is completed, the displacement component 4 drives the insertion component 2 to move toward the base 10. During the process, the lower visual component 6 visually identifies and locates the bottom of the connector 9 to check whether the petals are missing;

[0072] 3) When the insertion component 2 moves to the top of the base 10, the upper visual component 5 visually identifies and locates the socket 1001 on the base 10;

[0073] 4) The computer performs position compensation operation based on the recognition results of the upper visual component 5 and the lower visual component 6 to obtain the specific coordinate position of the connector 9 to be assembled and gives it to the displacement component 4. The displacement component 4 reaches the specified coordinate position based on the position fed back after the compensation operation;

[0074] 5) One of the offset cylinders 205 drives the corresponding connector 9 to move downward to stagger with other connectors 9 in height, and the displacement component 4 drives the insertion component 2 to move downward, and the pressure rod 203 corresponding to the connector 9 presses it downward to achieve insertion;

[0075] 6) After the insertion is completed, the 3D line scanning measuring instrument checks the XY axis position, Z axis height, and petal status of the connector 9, and qualified products flow to the next station.
