[0013] An embodiment of the present invention provides an automatic female pin assembly machine, which installs the female pin onto a plastic shell to complete the installation of the connector. The specific female pin assembly machine includes: a frame, a manipulator, a female pin loader, a first tooling, a safety sensor and a proximity sensor for tooling identification; for ease of understanding, the structure and working process of the entire female pin automatic assembly machine are described below. The frame includes an operating table and a protective cover arranged on the operating table. At least one side of the protective cover is selected to be acrylic, and the acrylic is selected to be brown. Since the acrylic is brown, the acrylic material has good light-shielding properties, and the brown color has a certain degree of transparency, which enables the protective cover to provide a certain field of view, making it convenient for operators to observe the operation of the equipment; because of the protective cover, it can also play a certain dust-proof role in the operating space formed by the protective cover and the operating table. In addition, the protective cover made of acrylic material has many advantages, mainly including the following points: Weather resistance: The acrylic protective cover has strong adaptability to the natural environment and is not easily affected by ultraviolet rays, rain and climate change. Even if it is exposed to sunlight, wind and rain for a long time, it will not change color or become brittle. Impact resistance: The impact resistance of acrylic material is many times that of ordinary glass. It is not easy to break. Even if it breaks, it will not form sharp fragments, reducing safety risks. Processing performance: Acrylic material is easy to cut, drill, hot bend, bond and form, suitable for various shapes and design requirements. Durability: Acrylic protective cover has good chemical corrosion resistance and wear resistance, and can be used for a long time in medical environments, reducing the frequency of replacement and maintenance, and reducing operating costs. Beautiful: The acrylic protective cover itself has a high gloss and texture, which can enhance the overall aesthetics. Easy to clean: The surface of acrylic material is smooth and flat, not easy to stain, and very easy to clean. Therefore, based on the above advantages, choosing acrylic material for the protective cover will improve the quality of the entire female pin automatic assembly machine to form a connector after the female pin and the plastic shell are installed. A manipulator, a needle loader and a first tooling are arranged in the protective cover. When these structures fail or require regular maintenance, the protective cover has an openable and closable safety door for easy operation. The safety door is usually in a closed state. When the structure in the operating space of the protective cover needs to be inspected, the safety door is opened; the safety door includes a door panel, a safety sensor and a door lock. The safety sensor and the door lock are both arranged on the upper part of the door panel. Specifically, there are two door locks and two safety sensors, and there are also two door panels. When the two door panels are close and completely closed, the two door locks installed on the top of the door panels are close and have a locking force to keep the two door panels in a closed state. When they are forcibly opened by external force, the external force here refers to a force that exceeds human power, that is, the strength design and the selection of the safety door lock here should be such that it cannot be destroyed by human power alone; after the safety sensor detects it, the equipment in the operating space will be cut off from power and gas, and shut down immediately to ensure the safety of the operator.A manipulator, a mother needle loader and a first tooling are arranged in the protective cover. A press-fitting assembly is installed on the mounting part at the bottom of the manipulator. The press-fitting assembly includes a cylinder and a press-fitting fixture for clamping the mother needle. The blowing pipe connects the mother needle loader with the press-fitting fixture. The blowing pipe blows the mother needle in the mother needle loader to the press-fitting fixture through airflow. The press-fitting fixture mainly clamps the mother needle. Then the cylinder drives the press-fitting fixture to move and presses the mother needle clamped by the press-fitting fixture into the plastic shell. The driving assembly of the manipulator realizes the control of the movement path of the press-fitting assembly. The specific working process is to transport the mother needle from the mother needle loader to the press-fitting fixture in the press-fitting assembly through the blowing pipe. The press-fitting fixture clamps the mother needle. Then the driving assembly moves to move the press-fitting assembly on the mounting part at the bottom of the manipulator. The press-fitting assembly moves to the plastic shell on the mounting plate of the first tooling. Then the cylinder in the press-fitting assembly drives the press-fitting fixture to press the mother needle into the plastic shell, so that it is relatively fixed with the plastic shell to complete the installation. Of course, in order to facilitate the quick replacement of the plastic shell, the first tooling can be slidably set on the operating table. Specifically, the first tooling includes a mounting plate and a quick-release part. The plastic shell is detachably set on the mounting plate through the quick-release part. The quick-release part here does not require the aid of tools, and the quick-release part can be removed manually. The mounting plate in the first tooling has a first station and a second station relative to the operating table. When the mounting plate is in the first station, the mounting plate is located outside the operating space. The plastic shell is manually installed and fixed on the mounting plate. At this time, the mounting plate is located outside the operating space and will not be injured due to misoperation of the manipulator; when the plastic shell is installed, the first tooling slides into the operating space, and the press-fitting assembly connected to the manipulator clamps the female needle and places it on the plastic shell. Since the mounting plate and the plastic shell are both located in the operating space at this time, the operator cannot touch the mounting plate and the plastic shell, which effectively protects the operator's safety. In order to further improve the degree of automation, a proximity sensor for tool identification is set on the operating table to detect the model of the installed mounting plate. Since different models of mounting plates are installed with plastic shells of different specifications, when a plastic shell of model I needs to be processed, the corresponding mounting plate of model I is mounting plate No. I. At this time, the proximity sensor for tool identification is used to identify whether the mounting plate is mounting plate No. I; if it is found that the mounting plate is not the required mounting plate No. I, then the first tool does not work. The whole process is not only highly mechanized and saves time, but also effectively protects the operator to avoid accidentally touching the mounting plate when the robot is working.

[0014] Optionally, the manipulator further includes: an image acquisition module, which is disposed on the press-fitting fixture and is used to acquire image information to locate the position of the plastic shell so as to determine the movement path of the manipulator.

[0015] Optionally, the first tool further includes a sliding assembly, wherein the sliding assembly is disposed between the operating table and the mounting plate, a first direction is a first direction from the first station to the second station, and a length direction of the sliding assembly is parallel to the first direction.

[0017] Optionally, the second tool further includes a sliding assembly, and the sliding assembly is disposed between the operating table and the mounting plate. The direction from the third station to the fourth station is a second direction, and the first direction is parallel to the second direction.

Beautiful: The acrylic protective cover 12 itself has a high gloss and texture, which can improve the overall aesthetics. Easy to clean: The surface of the acrylic material is smooth and flat, not easy to be stained, and very easy to clean. Therefore, based on the above advantages, choosing the protective cover 12 as acrylic material will improve the quality of the connector formed after the entire female pin B automatic assembly machine installs the female pin B and the plastic shell A.A manipulator 2, a female needle loader 3 and a first tooling 4 are arranged in the protective cover 12. When these structures fail or require regular maintenance, in order to facilitate operation, the protective cover 12 has an openable and closable safety door 121. The safety door 121 is usually in a closed state. When it is necessary to inspect and repair the structure in the operating space of the protective cover 12, the safety door 121 is opened; the safety door 121 includes a door panel 1211, a safety sensor 1212 and a door lock 1213. The safety sensor 1212 and the door lock 1213 are both arranged on the upper part of the door panel 1211. Specifically, the door lock 1213 There are two safety sensors 1212 and two door panels 1211. When the two door panels 1211 are close to each other and completely closed, the two door locks 1213 installed on the top of the door panels 1211 are close to each other and have a locking force so that the two door panels 1211 are in a closed state. When they are forcibly opened by external force, the external force here refers to the force exceeding human power.

After the safety sensor 1212 detects it, it will cut off the power and gas to the equipment in the operating space and shut it down immediately to ensure the safety of the operator. A manipulator 2, a female needle feeder 3 and a first tool 4 are arranged in the protective cover 12. A press-fitting assembly is installed at the mounting portion at the bottom of the manipulator 2. The press-fitting assembly includes a cylinder 221 and a press-fitting fixture 21 for clamping the female needle. The blowing pipe 32 connects the female needle feeder 3 with the press-fitting fixture 21. The blowing pipe 32 blows the female needles in the female needle feeder 3 to the press-fitting fixture 21 through airflow. The main function of the press-fitting fixture 21 is to clamp the female needle B. Then the cylinder 221 drives the press-fitting fixture 21 to move and clamp the female needle B clamped by the press-fitting fixture 21. Pressed into the plastic shell A, the driving component 22 of the manipulator 2 realizes the control of the movement path of the press-fitting component. The specific working process is to transport the mother needle from the mother needle loader to the press-fitting fixture in the press-fitting assembly through the blowing tube 32, the press-fitting fixture clamps the mother needle, and then the driving component is actuated to move the press-fitting assembly on the mounting part at the bottom of the manipulator, and the press-fitting assembly moves to the plastic shell A on the mounting plate 41 of the first tooling 4, and then the cylinder 221 in the press-fitting assembly is actuated to drive the press-fitting fixture to press the mother needle into the plastic shell, so that it is relatively fixed to the plastic shell to complete the installation.Of course, in order to facilitate the quick replacement of the plastic shell, the first tooling can be slidably set on the operating table 11. Specifically, the first tooling 4 includes a mounting plate 41 and a quick-release part 42. The plastic shell is detachably set on the mounting plate through the quick-release part. The quick-release part here does not require the aid of tools, and the quick-release part can be removed manually. The mounting plate in the first tooling has a first station and a second station relative to the operating table. When the mounting plate is in the first station, the mounting plate is located outside the operating space. The plastic shell is manually installed and fixed on the mounting plate. At this time, the mounting plate is located outside the operating space, and will not be injured due to misoperation of the manipulator; when the plastic shell is installed, the first tooling slides into the operating space, and the press-fitting assembly connected to the manipulator clamps the female needle and places it on the plastic shell. Since the mounting plate and the plastic shell are both located in the operating space at this time, the operator cannot touch the mounting plate and the plastic shell, which effectively protects the safety of the operator. In order to further improve the degree of automation, a proximity sensor for tool identification is set on the operating table to detect the model of the installed mounting plate. Since different models of mounting plates are installed with plastic shells of different specifications, when a plastic shell of model I needs to be processed, the corresponding mounting plate of model I is mounting plate No. I. At this time, the proximity sensor for tool identification is used to identify whether the mounting plate is mounting plate No. I; if it is found that the mounting plate is not the required mounting plate No. I, then the first tool does not work. The whole process is not only highly mechanized and saves time, but also effectively protects the operator to avoid accidentally touching the mounting plate when the robot is working.

[0048] Continue to refer Figure 1 , Figure 1 A schematic diagram of the three-dimensional structure of a female needle B automatic assembly machine provided by an embodiment of the present invention; a tower light 9 is arranged at the top of the protective cover 12, and the tower light 9 arranged at the top is the most conspicuous to ensure 360-degree panoramic visibility, and can be clearly seen by operators at a distance even in a busy industrial environment. Such a setting helps to transmit equipment status information in a timely manner and improve production efficiency and safety.

[0049] In some specific embodiments, the female needle B automatic assembly machine provided in the embodiment of the present invention further includes an electronic device 7, which is used to monitor the working state of the female needle automatic assembly machine. Specifically, the electronic device 7 can be an electronic screen, and the operator can observe the power-on and power-off status of each component of the female needle automatic assembly machine in real time, so as to operate the two-hand start-stop button 13 outside the protective cover 12 in time to control the equipment inside the protective cover 12.

[0050] In addition, a gas source port 122 is provided at the top of the protective cover 12, and the gas source port 122 is connected to the gas source processing assembly. The gas source port 122 is used to achieve the effect of air pressure communication between the operating space of the protective cover 12 and the external space.

[0051] A two-hand start-stop button 13 is provided outside the operating space on the operating table 11. The benefits of designing the two-hand start-stop button 13 are mainly reflected in improving operational safety and preventing accidental injuries. The following are some specific benefits: Enhanced safety: The two-hand start-stop button requires the operator to press the button with both hands at the same time to start or stop the equipment, which can ensure that the operator's hands are outside the safe distance to avoid injuries caused by misoperation. Prevent one-handed operation: By requiring both hands to be pressed at the same time by design, it is prevented that the operator operates with one hand in order to catch up with the progress or for convenience, thereby violating the safety operating procedures. Time difference control: The two-hand button usually requires that the two buttons are pressed at the same time within a very short time difference to be effective, which further ensures that the operator must use both hands at the same time. A safety grating 10 is provided on the protective cover. The safety grating 10 detects whether there is an object passing through by emitting and receiving light beams, thereby protecting the safety of personnel and equipment. Not only improves safety, but also significantly improves production efficiency and management level. There are many options for the safety grating 10, such as finger detection, palm detection and arm detection. In the embodiment of the present invention, the safety grating 10 is selected for palm detection, that is, the optical axis distance between the gratings is 20 mm.

[0052] The automatic assembly machine for the female needle B provided in the embodiment of the present invention also includes an air source processing component 8, which is located at the bottom of the operating table 11, and is used to provide an air source to the female needle loader 3. Placing the air source processing component 8 at the bottom is usually more stable, and can provide a stable installation platform for the air source processing component 8, reducing component damage caused by equipment vibration. The bottom position is convenient for staff to carry out daily inspection and maintenance work, such as replacing filters, adjusting pressure reducing valves, etc. The space at the bottom of the equipment is often spacious, which is conducive to the installation and integration of the air source processing component 8, and at the same time will not occupy the main working area of ​​the equipment.

[0053] Continue to refer Figure 2 , Figure 2 It is an openable and closable safety door 121 in the protective cover 12. The safety door 121 includes a door panel 1211, a safety sensor 1212 and a door lock 1213, all of which are arranged on the door panel 1211. The safety door 121 cannot be opened without permission because the door lock 1213 has a locking force that keeps the safety door 121 in a closed state. When an external force exceeding the locking force is used to open the door panel 1211, the safety sensor 1212 detects that the position of the door panel 1211 has changed, and controls the automatic assembly machine of the female needle B to stop working. There are two door panels 1211. When it is necessary to inspect and repair the equipment inside the operating space, the door panel 1211 is opened by pulling the two handles 1214 on the door panel 1211. The door panel 1211 is installed on the protective cover 12 through the hinge 1216.

[0054] like Figure 3 As shown, Figure 3 In order to open the protective cover 12, a manipulator 2, a female needle loader 3, a processor 14, a first tooling 4, a second tooling 6, and a proximity sensor 5 for tooling identification located between the first tooling 4 and the second tooling 6 are installed on the operating table 11; the first tooling 4 and the second tooling 6 are respectively in different workstations, the first tooling 4 is in the first workstation, that is, located outside the protective cover 12, and the second tooling 6 is in the fourth workstation, that is, located inside the protective cover 12.

[0055] For ease of understanding, the opening 31 of the mother needle loader 3 is used to place the mother needle. The mother needle loading bin is only for storing materials. The mother needle loader 3 also includes a vibrator and a pneumatic cutting structure. The vibration of the vibrator can make the mother needle move forward. There is a pneumatic cutting structure in front of the vibrator. Then the mother needle B is blown to the press-fitting fixture at the bottom of the manipulator 2 through the blowing pipe 32. The mother needle B is blown to the press-fitting fixture by the blowing pipe 32. The gas in the blowing pipe 32 is provided by the air source processing component 8.

[0056] For ease of understanding, continue to refer to Figure 4 ,exist Figure 4 In the figure, the first tooling 4 is in the first station. At this time, the first tooling 4 also includes a sliding assembly 43. The sliding assembly 43 is arranged between the operating table 11 and the mounting plate 41. The direction from the first station to the second station is the first direction. The length direction of the sliding assembly 43 is parallel to the first direction. The sliding assembly 43 of the first tooling 4 includes a slide rail 431 and a slider corresponding to the slide rail 431. The slide rail 431 is arranged on the operating table 11, and the slider is arranged on the mounting plate 41. There are two slide rails 431 and two sliders in the first tooling 4. The two slide rails 431 are arranged on the operating table 11 at intervals. The two slide rails 431 make the movement process of the mounting plate 41 more stable. In addition, a servo motor 432 is also arranged on the operating table 11, and the mounting plate 41 is driven to move along the length direction of the slide rail 431 by the servo motor.

[0057] Similarly, the structure and principle of the second tooling 6 are basically the same as those of the first tooling 4. Specifically, the second tooling 6 can be slidably arranged on the operating table 11. The second tooling 6 includes a mounting plate 41 and a quick release part 42. The plastic shell A can be detachably arranged on the mounting plate 41 through the quick release part 42. The mounting plate 41 has a third station and a fourth station relative to the operating table 11. When the mounting plate 41 is in the third station, the mounting plate 41 is located outside the operating space; when the mounting plate 41 is in the fourth station, the mounting plate 41 is located in the operating space, and the manipulator 2 clamps the female needle B and places it on the plastic shell A. The sliding assembly 43 of the second tooling 6 includes a slide rail 431 and a slider corresponding to the slide rail 431. The slide rail 431 is arranged on the operating table 11, and the slider is arranged on the mounting plate 41. The second tooling 6 also includes a sliding assembly 43, which is arranged between the operating table 11 and the mounting plate 41. The direction from the third station to the fourth station is the second direction, and the first direction is parallel to the second direction. There are two slide rails 431 and two slide blocks in the second tooling 6 , and the two slide rails 431 are arranged on the operating table 11 at intervals.

[0058] like Figure 5 As shown, the first tooling 4 here includes a mounting plate 41, which is quickly installed and removed by a quick release part 42, and has a plurality of notches on the mounting plate 41, in each of which a plastic shell A is installed. Of course, the specifications of the plastic shell A may be different. If the plastic shell A adopts different specifications, the mounting plate 41 with a suitable notch can be directly replaced. Different plastic shells A require different mounting plates 41. When the mounting plate 41 needs to be replaced, it is only necessary to twist or pull the quick release part 42, and then pull the handle 44 to achieve a quick replacement of the mounting plate 41.

[0059] like Figure 6 and Figure 7 As shown, the manipulator 2 also includes: an image acquisition module 23, which is arranged on the press-fitting fixture 21, and is used to acquire image information to locate the position of the plastic shell A, so as to determine the movement path of the manipulator 2. It can be understood that the position of the plastic shell A located on the first tooling is acquired by photographing through the image acquisition module 23, and then the driving component of the manipulator moves to transport the press-fitting fixture to the position of the plastic shell A where the female needle B needs to be pressed. The specific driving component 22 of the manipulator 2 is a four-axis motor 222, and the movement of the four-axis motor 222 realizes the movement of the path of the press-fitting fixture 21 on the horizontal plane, and the movement of the cylinder 221 realizes the movement of the press-fitting fixture 21 in the vertical plane, that is, the female needle B is pressed against the plastic shell A by approaching the plastic shell A.

[0060] like Figure 8-Figure 11 , showing different types of connectors after the plastic shell A and the female pin B are connected, Figure 8 and Fig. 9 For a row of female pins B without locking, female pin B from 2PIN ( Fig. 9 ) to 25PIN ( Figure 8 ), the hole distance of the female pin B is 2mm, that is, for every additional female pin B, the length of the plastic shell A increases by 2mm, and there is no other dimensional change.

[0061] Figure 10-11 There is no locking for two rows of pins, and the female pin B is from 4PIN ( Fig.11 ) to 50PIN ( Fig.10 ), the hole spacing of the female pin B is 2mm, that is, for every additional row of female pins B, the length of the plastic shell A increases by 2mm, and there is no other dimensional change.

[0062] To facilitate understanding of the solution, Fig.12 As shown, Fig.12 A schematic diagram of the structure of the first tooling 4 and the proximity sensor for tooling identification provided in this embodiment; the side of the mounting plate 41 of the first tooling 4 is provided with identification blocks 45, and the number of identification blocks 45 is installed at different positions, and different numbers of identification blocks 45 represent different types of mounting plates 41 and types of plastic shells A corresponding to the mounting plates 41. Of course, in order to facilitate the installation of the identification blocks 45, a plurality of holes are provided on the side of the mounting plate 41. The proximity sensor 5 for tooling identification realizes the identification and determination of the type of plastic shell A on the mounting plate 41 by identifying the number and position of the identification blocks 45.

[0063] like Figure 13-Figure 15 As shown in the figure, from left to right are: manual switch valve 81, filter pressure reducing valve 82, electric control switch valve 83, soft start valve 84, gas distributor 85. The function of manual switch valve 81 is to manually control the on and off of the gas source. As shown in the figure, it is off-circuit, and it is on-circuit when rotated 90 degrees. When it is off-circuit, the airflow direction is Fig.13 The flow in the direction indicated by the dotted arrow is used to release the residual pressure of the equipment. This is for safety reasons. The bottom of the switch valve is a muffler (not shown in the figure). When the equipment is a passage, the airflow flows into the equipment in the direction of the arrow, and the equipment works normally. The essential principle of this valve is a two-position three-way manual reversing valve. See Fig.14 , the two squares represent two positions. When in the left position, 1' to 2' is the passage, and the equipment takes in air (as shown by the solid arrow). When in the right position (as shown by the symbol), 2' to 3' is the passage (as shown by the dotted arrow), and the equipment releases residual pressure. In the gas path symbol, 1' represents the gas source inlet, 2' represents the gas source outlet, which is also the port for entering the equipment, and 3' represents the pressure relief port.

[0064] The filter pressure reducing valve 82 has a compact structure, integrating the pressure reducing valve and the filter valve into one unit, and has very good particle separation, large flow, and minimal hysteresis. The pressure adjustment range is 0.5bar-12bar. The blue knob on the top is turned clockwise to increase the pressure, and clockwise to decrease the pressure. The pressure gauge in front is used to display the pressure value. The lower barrel is the filter, and the blue part at the bottom is the drain port.

[0065] The principle of the electric control switch valve 83 is the same as that of the manual switch valve, except that one is manually controlled and the other is electrically controlled. When someone breaks into the grating or opens the safety door illegally, the device will cut off the gas source from here for safety reasons and release the residual pressure (the same as the principle of manual switch valve pressure relief). The gas path symbol is only different on the left side, which is the control method.

[0066] The soft start valve 84 is essentially a two-way valve for slowly ventilating pneumatic equipment with electrically switchable pressure switching points. The supply voltage is 24 V DC. It is used to slowly and safely move the drive to the initial position to avoid sudden and unpredictable movements. The pressure build-up time can be set.

[0067] The gas distributor block 85 is an aluminum block with four ports, the left and right ports are used for air intake and outlet, the upper port is not working and is sealed with a plug, and the lower port is used for connecting a pressure switch.

[0068] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
