[0042] The press-fitting mechanism 41 includes two groups of press-fitting mechanisms, which are respectively installed on the rack between two adjacent groups of the gripping mechanisms, and the outer edge of the turntable is arranged in the middle of the press-fitting mechanism.

[0043] In this embodiment, each vibrating loading tray is used for vibrating loading of a material. Four groups of grabbing mechanisms grab the materials transported in each vibrating loading tray respectively, grab them and place them on the corresponding receiving parts, and the pressing mechanism presses the corresponding parts. Among them, a third driving mechanism 17 is provided on the frame, and the third driving mechanism is configured to drive the turntable to rotate.

The third driving mechanism can be a combination of a motor and a reducer, or a combination of a motor and a belt. Among them, there are at least 7 through holes and at least 7 material receiving pieces.

Every time the turntable rotates once, 5 material receiving pieces will be respectively located below the inner ends of the 5 groups of material transfer mechanisms, 2 material receiving pieces will respectively face the two groups of pressing mechanisms, and one material receiving piece will be empty. In this way, there are 7 workstations.

[0044] See also Figure 1 , 2As shown, the material grabbing mechanism includes a shell material grabbing mechanism 8, a first supporting medium material grabbing mechanism 9, a center needle material grabbing mechanism 10, a second supporting medium material grabbing mechanism 11 and a material unloading mechanism 12 which are arranged in a counterclockwise order outside the turntable, and the pressing mechanism includes a first supporting medium material pressing mechanism 13 and a center needle material pressing mechanism 14, the first supporting medium material pressing mechanism 13 is arranged between the first supporting medium material grabbing mechanism 9 and the center needle material grabbing mechanism 10, and the center needle material pressing mechanism 10 is arranged between the center needle material grabbing mechanism 10 and the second supporting medium material grabbing mechanism 11;

[0045] The four groups of vibrating loading trays are respectively arranged beside the shell grabbing mechanism, the first supporting medium grabbing mechanism, the center needle grabbing mechanism and the second supporting medium grabbing mechanism. No vibrating loading tray is arranged beside the unloading mechanism, which is used for unloading the assembled product, and no loading step is required.

[0046] Among them, a group of vibrating feeding discs are used for feeding the outer shell. The outer shell is grabbed by the outer shell grabbing mechanism and placed in the receiving slot of a receiving piece. Then the turntable rotates a predetermined angle so that the receiving piece will rotate to the next station. At this time, another vibrating feeding disc is used for feeding the first supporting medium. In this embodiment, the first supporting medium is an insulator. The first supporting medium is grabbed by the first supporting medium grabbing mechanism and placed in the outer shell. Then the turntable rotates a predetermined angle again, and the receiving piece is rotated into the first supporting medium pressing mechanism. The first supporting medium and the shell are pressed by the first supporting medium pressing mechanism to realize the pressing of the two components. Then the turntable rotates a predetermined angle again and rotates to the next station. At this time, another vibrating feeding disc is used for feeding the center needle. In this embodiment, the center needle is an inner conductor. Then the center needle grabbing mechanism grabs the center needle and places it on the insulator assembled to the shell. Then the turntable rotates a predetermined angle again and rotates to the next station, so that the receiving piece is rotated into the center needle pressing mechanism. The center needle pressing mechanism presses the center needle into the insulator to complete the assembly of the two. Then the turntable drives the receiving piece to rotate to the next workstation, and another vibrating loading plate loads the second supporting medium. In this embodiment, the second supporting medium is an insulating ring. The second supporting medium grabbing mechanism grabs the insulating ring and directly installs it into the shell to complete the assembly of the second supporting medium. Then the turntable rotates a predetermined angle again, so that the receiving piece of the assembled product rotates to the unloading mechanism, and the unloading mechanism grabs and removes the assembled product from the receiving piece to realize the assembly of a product.

[0047] During the rotation of the turntable, each workstation operates synchronously, which can achieve continuous assembly of connector joints with high assembly efficiency and good quality.

[0048] See also Figure 1 , 2As shown in , 4, 5, and 7, the material grabbing mechanism includes a material grabbing member 15 and a driving mechanism for driving the material grabbing member 15 to move horizontally and vertically, and the bottom of the material grabbing member 15 is a material grabbing end;

[0049] The material grabbing member 15 and the driving mechanism are installed on the frame 1 via a stand 16 .

[0050] Among them, in this embodiment, the grasping parts in different processes can be different, and can be selected according to the actual situation. Among them, the grasping parts in the shell grasping mechanism are pneumatic clamps or electric clamps (in this embodiment, the clamps are all pneumatic clamps as an example), and the shell in the vibrating loading tray is grasped by the pneumatic clamps and placed in the receiving trough. The grasping parts in the first supporting medium grasping mechanism can directly use suction cups or straws, or other negative pressure suction parts to suck the insulator from the vibrating loading tray and put it into the shell. Of course, it can also be other mechanisms for grasping insulators. It can also be a pneumatic clamp that can grasp and lower the insulator. The grasping parts in the center needle grasping mechanism can also be starting clamps or suction cups (taking suction cups as an example, it can also be other negative pressure suction parts), which can grasp the center needle. In this embodiment, it uses pneumatic clamps. The grasping parts in the second supporting medium grasping mechanism use suction cups to absorb, grasp and discharge the insulating ring. The grabbing parts in the unloading mechanism also use pneumatic grippers to grab and lower the assembled products.

[0051] See also Figure 1 , 2 As shown in , 4, 5, and 7, the driving mechanism includes a horizontal cylinder 18 and a vertical cylinder 19, the output shaft of the horizontal cylinder 18 is arranged toward the axis of the turntable 2, the output shaft of the horizontal cylinder 18 is arranged parallel to the top surface of the turntable 2, and the output shaft at the bottom of the vertical cylinder 19 is arranged perpendicular to the top surface of the turntable 2;

[0052] The vertical frame 16 is provided with a horizontal slide rail 20, and a mounting frame 21 is slidably provided on the horizontal slide rail 20. The output shaft of the horizontal cylinder 18 is connected to the mounting frame 21. The horizontal cylinder 18 pushes the mounting frame 21 to move along the horizontal slide rail 20. One end of the horizontal slide rail 20 is arranged directly above the turntable 2, and the other end is arranged above the frame 1 outside the turntable 2.

[0053] The mounting frame 21 is provided with a vertical slide rail 22, and a bracket 23 is slidably mounted on the vertical slide rail 22. The grabbing piece 15 is mounted on the bracket 23. The vertical cylinder 19 is mounted on the mounting frame 21 above the bracket 23. The output shaft at the bottom of the vertical cylinder 19 is connected to the bracket 23. The vertical cylinder 19 drives the bracket 23 and the grabbing piece 15 to move vertically along the vertical slide rail 22.

[0054] In this embodiment, when the horizontal cylinder output shaft extends, it pushes the mounting frame to move to the top of the turntable, so that the material grabbing piece is located above the material receiving piece. When the horizontal cylinder output shaft retracts, it pulls the mounting frame to move to the outside of the turntable, so that the material grabbing piece is located at the top of the vibrating loading plate, grabs the material to be assembled, or grabs and puts down the assembled product from the material receiving piece. It can realize the reciprocating movement of the material grabbing piece between the material receiving piece and the outside of the turntable. The vertical cylinder can drive the bracket and the material grabbing piece to move vertically, so that the material grabbing piece can grab and put down the material. For example, when loading the shell, the horizontal cylinder output shaft retracts first, driving the grabbing piece to be above the vibrating loading tray, and then the vertical cylinder output shaft extends, driving the grabbing piece to move down, and then the grabbing piece grabs the shell. After grabbing, the vertical cylinder output shaft retracts, and the grabbing piece drives the shell to move up and away from the vibrating loading tray, and then the horizontal cylinder output shaft extends, driving the grabbing piece and the shell to move to the top of a receiving piece, and then the vertical cylinder output shaft extends, driving the grabbing piece and the shell to move down, so that after the shell is placed in the receiving slot, the grabbing piece releases the shell, and then the vertical cylinder output shaft retracts, driving the grabbing piece to rise and away from the shell, and then the horizontal cylinder output shaft retracts, so that the grabbing piece moves to the top of the vibrating loading tray, waiting for the next shell to be loaded, and so on. The principle of loading or unloading other components or products is the same.

[0055] See also Figure 1 , 2 As shown in , 4, 5, and 7, a discharging chute 24 is provided on the discharging end of the vibrating loading plate 7, and a pushing mechanism is provided on the discharging end of the discharging chute 24, and the pushing mechanism includes a support frame 25, a pushing block 26 and a pushing cylinder 27, and the output shaft of the pushing cylinder 27 is arranged toward the axis of the turntable 2, and the bottom of the support frame 25 is installed on the frame 1, and a slide groove 28 is provided on the support frame 25, and the side wall of the slide groove 28 is provided with a notch 29 connected with the discharging chute 24, and the pushing block 26 is slidably arranged in the slide groove 28, and a clamping port 30 is provided on the side wall of the pushing block 26, and when the output shaft of the pushing cylinder is retracted, the clamping port is arranged opposite to the notch, and when the output shaft of the pushing cylinder is extended, the clamping port is arranged at the inner end of the notch.

[0056] In this embodiment, the vibrating loading plate vibrates and sorts the materials and feeds them onto the discharging chute. The materials are sorted and transported on the discharging chute in sequence. In order to ensure that one product is grabbed each time and to prevent other materials on the discharging chute from being lifted up when the material is grabbed, the pushing mechanism is set up. The material on the discharging chute will move toward the discharging chute, enter the gap first, and contact the pushing block first. When a material needs to be transported, the output shaft of the pushing cylinder retracts so that the clamping port is opposite to the gap. The size of the clamping port is the size width of a product. In this way, a product will enter the clamping port, the next product will be in the gap, and the product at the rear end will be in the discharging chute. Then the output shaft of the pushing cylinder extends to drive the pushing block to move, and the clamping port drives a product to move inward, close to the turntable. When the horizontal cylinder output shaft is retracted, the grabbing piece will be directly above the material (product), so that the material in the clamping port can be grabbed by the grabbing mechanism and put into the receiving trough for placement, assembly and other processes.

[0057] See also Figure 4 , 5 As shown, a pneumatic clamp 31 is further provided at the bottom of the bracket 23 in the center needle material grabbing mechanism 10 , and the pneumatic clamp 31 is arranged directly below the material grabbing member 15 .

[0058] In this embodiment, the center needle (the inner conductor is a metal part with a smaller diameter) is easy to deform, and the grabbing piece will only grab the top of the center needle. When it is grabbed and moved from the vibrating loading tray to the receiving trough, that is, when the center needle is placed in the middle of the insulator, its bottom may be deformed and cannot be inserted into the insulator. Therefore, a pneumatic clamp will be provided at the bottom of the bracket in the center needle grabbing mechanism, which will be provided directly below the grabbing piece. The grabbing piece grabs the top of the center needle, and the pneumatic clamp clamps the bottom of the center needle, thereby preventing the center needle from deforming, thereby ensuring that when the center needle is moved down, the bottom of the center needle can be inserted into the outer shell equipped with the insulator, and its bottom can be inserted into the middle of the insulator, thereby ensuring that the subsequent center needle can be smoothly pressed into the inside of the insulator.

[0059] See also Figure 3 As shown, an upper limit member 32 is provided above the material receiving member 3, and a lower limit member 33 is provided at the bottom of the material receiving member 3. The upper limit member 32 is provided above the turntable 2, and the lower limit member 33 is provided below the turntable 2. The distance between the upper limit member and the lower limit member is greater than the thickness of the turntable. In a normal state, since the material receiving member is under weight, the material receiving member descends, and the upper limit member is used to limit the material receiving member from falling out of the through hole. When the material receiving member moves upward, it will be limited by the lower limit member to prevent the material receiving member from moving upward and leaving the through hole.

[0060] Among them, in this embodiment, the material receiving groove is set at the top of the material receiving piece, the shell will be placed in the material receiving groove, and then the insulator is placed in the shell, and then the insulator is pressed into the shell, and then the bottom of the center pin (inner conductor) is inserted into the middle of the insulator, and then the center pin and the insulator are pressed, and finally the insulating ring is installed in the shell to complete the assembly of the connector joint. At the same time, in this embodiment, the material receiving piece can also rotate in the through hole, which will not affect the assembly of the connector joint, because it is a standard ring structure and can be assembled at any angle.

[0061] See also Figure 1 , 2 As shown in Figure 6, the pressing mechanism 41 includes a pressing bracket 34, an upper pressing head 35 and a lower supporting head 36. The pressing bracket 34 is provided with an upper driving member 37 for driving the upper pressing head 35 to move vertically, and a lower driving member 38 for driving the lower supporting head 36 to move vertically. The upper pressing head is arranged directly above the lower supporting head, and the upper pressing head is arranged above the turntable, and the lower supporting head is arranged below the turntable.

[0062] In this embodiment, if the pressing mechanism only adopts the downward pressing method, after the downward pressing, the pressure will be transmitted to the turntable, which may cause the turntable to be deformed by pressure and cause the rotation to be not smooth, etc. Therefore, by setting the upper pressing head and the lower supporting head, the material receiving part can move up and down, so that during the subsequent pressing, the lower supporting head moves up, pushes the upward moving part of the material receiving part, and supports the material receiving part, and the upper pressing head also moves down to press the product (the upper pressing head of the first supporting medium pressing mechanism gives the first supporting medium downward pressure, and the upper pressing head of the center needle pressing mechanism gives the center needle downward pressure. The shapes of the upper pressing heads in the two pressing mechanisms are different, mainly for pressing the corresponding materials), and the assembly of the insulator and the center needle is realized. In this way, during the assembly, the pressing force will only be applied through the lower supporting head, and will not be transmitted to the turntable, so as to prevent the damage and deformation of the turntable. Among them, the upper driving member can be an upper cylinder, and the top of the upper pressing head is connected to the output shaft at the bottom of the upper cylinder to drive the upper pressing head to move up and down. The lower driving member may also be a lower cylinder, which pushes the lower support head up and down. Of course, the upper and lower driving members may also be other driving methods, such as electric cylinders, wedge blocks, etc., as long as they can drive the corresponding upper pressing head and lower support head to move up and down.

[0063] See also Figure 2 , 7 As shown, the frame 1 below the second supporting medium grabbing mechanism 11 is also provided with a lifting member, and the lifting member is arranged directly below the turntable;

[0064] The lifting member includes a lifting block 39 and a lifting driving mechanism 40 for driving the lifting block 39 to move up and down. The lifting driving mechanism drives the lifting block to be disposed close to or away from the bottom surface of the turntable.

[0065] In this embodiment, the lifting drive mechanism adopts a cylinder or an electric cylinder, which drives the lifting block to move up and down. When in use, the second supporting medium grabbing mechanism grabs the insulating ring, and then puts it down on the shell equipped with insulators and center pins, which will be sleeved on the outside of the center pin, and then the lifting drive mechanism drives the lifting block to rise, which pushes the material receiving piece to rise. When the material receiving piece rises, it synchronously drives the shell to rise, while the insulating ring does not move, so that the insulating ring will be loaded into the shell, and the assembly of the insulating ring is realized, which is efficient and of good quality. It does not need to set up a separate work station and process, and the assembly efficiency is high and the finished product is cheap. After the assembly is completed, the second supporting medium grabbing mechanism releases the insulating ring, and then the lifting block descends, and the material receiving piece automatically descends under the weight, so that the whole product is assembled. Then the turntable rotates the corresponding angle again, and rotates to the discharge mechanism. The discharge mechanism grabs the assembled product from the receiving slot of the receiving piece and moves it outward to make it separate from the turntable. Among them, a receiving bucket will be placed on the frame, and the unloading mechanism will grab the assembled products and put them into the receiving bucket to realize the rapid collection of products.
