Description

Technical Field

[0001] This application relates to the field of assembly machine technology, specifically to an automatic assembly machine for push connectors. Background Technology

[0002] Push connectors are interface designs that enable quick connection and locking through simple push-pull actions. They are widely used in industrial automation, communication equipment, and other scenarios. They support high-density layouts and modular designs, and consist of two parts: a plug and a socket. When the plug is inserted into the socket, the internal spring, latch, or self-locking mechanism automatically locks it to ensure a secure connection. By gently pulling the plug or pressing the unlocking ring, the locking structure is released, and the plug can be quickly pulled out.

[0003] Existing technologies mostly employ a single-station linear assembly method, where each part needs to be assembled sequentially in a fixed position. For example, after the plastic shell is positioned, small parts such as buttons and springs need to be installed manually or by semi-automatic equipment one by one, resulting in a long assembly time for each part and making it unsuitable for rapid production needs. Secondly, most existing equipment only has a continuity test step and cannot detect whether the terminal installation height meets the tolerance requirements. Since push connectors need to be precisely matched with the mating socket, a terminal height deviation of more than 0.1mm will lead to poor contact, and manual sampling inspection methods cannot guarantee full inspection coverage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic assembly machine for push connectors, which has the advantages of automatic assembly and inspection and sorting, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic assembly machine for push connectors, comprising a multi-station rotary divider, wherein multiple carriers for positioning push connector assemblies are fixedly mounted on its bearing surface, and the carriers intermittently move to each station as the divider rotates;

[0006] The component supply and assembly unit includes a first vibratory plate for supplying the plastic shell and a corresponding first gripping robot arm;

[0007] The second vibratory plate used to supply power to the first button and the corresponding second gripping robot arm;

[0008] The third vibrating disc and the corresponding third gripping robot are used to supply the first spring;

[0009] The fourth vibratory disk and the corresponding fourth gripping robot are used to supply power to the second button;

[0010] The fifth vibratory disc and the corresponding fifth gripping robot are used to supply the second spring;

[0011] The first to fifth gripping robots sequentially grip the corresponding parts and place them into the designated holes in the plastic shell inside the carrier located at a specific workstation, thus completing the installation of the button and spring.

[0012] The terminal processing unit includes a terminal tray for continuous supply of terminals;

[0013] A terminal clamping and cutting mechanism is used to receive terminal strips from a terminal tray, clamp a single terminal, and cut it off at the connection point with the strip.

[0014] Terminal insertion mechanism for inserting the cut-off terminals into the plastic housing of the assembled components within the carrier;

[0015] Terminal strip breaking mechanism, used to swing and break off the residual strip attached to the terminal;

[0016] The terminal riveting and shaping mechanism is used to perform secondary riveting and shape shaping on the terminals that have been inserted into place;

[0017] The test unit includes a continuity test mechanism for testing the electrical continuity performance of the internal terminals of the assembled connector;

[0018] A height testing mechanism is used to check whether the installation height of the assembled back-end components meets the requirements.

[0019] The sorting unit includes a sorting robot for grabbing and removing good products that have passed the test.

[0020] Furthermore, the multiple vibratory feeders and their corresponding gripping robots contained in the component supply and assembly unit are arranged sequentially around the multi-station rotary divider, corresponding to the workstations where each component is assembled in sequence.

[0021] The above solution achieves synchronization between parts supply and assembly processes. After the plastic shell is positioned, the buttons and springs are picked up by the robot in a preset order and precisely assembled into the designated holes, reducing material handling paths and waiting time, and improving assembly efficiency.

[0022] Furthermore, the terminal clamping and cutting mechanism, the terminal insertion mechanism, the terminal strip breaking mechanism, and the terminal riveting and shaping mechanism are arranged sequentially around the multi-station rotary divider after the component supply and assembly unit.

[0023] The above solution enables automatic cutting and riveting of terminals.

[0024] Furthermore, the terminal continuity testing mechanism and the terminal height testing mechanism are arranged sequentially around the multi-station rotary divider after the terminal processing unit.

[0025] The above solution enables automatic detection of finished products.

[0026] Furthermore, the sorting robot is located at a workstation following the testing unit.

[0027] The above solution enables the automatic sorting and separation of finished and defective products.

[0028] Furthermore, the terminal strip breaking mechanism uses a horizontal reciprocating swing motion to break the residual strip.

[0029] The above solution can effectively prevent the phenomenon of empty terminals caused by incomplete cutting of the material strip, thereby improving the yield.

[0030] Furthermore, each of the carriers includes a fixed base and a placement base that are fixedly connected to the divider. The upper surface of the placement base is provided with a placement groove for placing the plastic shell. The fixed base is provided with a pressing cylinder that is perpendicular to the upper surface of the divider in the height direction. The output end of the pressing cylinder is fixedly connected with a pressing plate that is parallel to the upper surface of the divider for fixing the plastic shell placed inside the placement groove.

[0031] The above solution avoids misalignment during the assembly of the first or second spring.

[0032] Furthermore, both the third and fifth gripping manipulators include a support frame. A rotary cylinder is fixedly installed on the inner wall of the support frame. A flipping block is fixedly connected to the output end of the rotary cylinder. A sealing protrusion is provided on the surface of the flipping block. A limiting groove adapted to the diameter of the external spring is opened on one side of the flipping block. A pneumatic slide rail is provided at the top of the support frame and radially arranged with the divider. A transfer plate is slidably connected to the pneumatic slide rail along its length. A vertically arranged first lifting cylinder is installed on the surface of the transfer plate. A lifting block is fixedly connected to the output end of the first lifting cylinder. A vertically arranged pin is installed at the bottom end of the lifting block. A clamping cylinder is installed on the surface of the lifting block. A clamping plate is fixedly connected to the output end of the clamping cylinder.

[0033] With the above scheme, after the first spring or the second spring flips, the first lifting cylinder drives the pin to move downward and insert it into the first spring or the second spring. Then, the clamping cylinder drives the clamping plate into the limiting groove and slides to contact the circumferential surface of the first spring or the second spring, so as to achieve the purpose of clamping the spring. Then, the first lifting cylinder resets and moves the first spring or the second spring to the top of the divider through the pneumatic slide rail, preparing the first spring or the second spring to be assembled with the plastic shell.

[0034] Furthermore, the support frame is provided with a button limiting mechanism on one side near the divider for limiting the first button or the second button. The button limiting mechanism includes a second lifting cylinder, the output end of which is fixedly connected to a button limiting frame, the top of which is equipped with an inclined button limiting cylinder, and the output end of which is fixedly connected to a button pressing rod.

[0035] With the above scheme, when the third or fifth gripping robot is preparing to assemble the first or second spring, the pressing plate fixes the upper surface of the plastic shell to prevent it from shifting. The second lifting cylinder drives the pressing cylinder to move upward, and one end of the pressing rod of the pressing cylinder is inserted into the plastic shell and positioned above the installed first or second button. Then, the second lifting cylinder moves downward to limit the first or second button, facilitating the installation of the first or second spring. After the first or second button is limited, the first lifting cylinder drives the first or second spring to be inserted into the mounting hole of the plastic shell. At the same time, the clamping plate separates from the first or second spring, completing the spring installation process. Finally, the third or fifth gripping robot resets, and the button limiting mechanism resets, starting the next first or second spring installation process.

[0036] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0037] This automatic assembly machine for push connectors enables parallel operation of each station through the intermittent rotation of the carrier. In the parts supply and assembly unit, components such as plastic shells, buttons, and springs are picked up and assembled by the robotic arm in a preset order, reducing material handling and waiting time in traditional single-station linear assembly and realizing continuous production.

[0038] With the sequential arrangement of the vibratory feeder and the gripping robot, each part is automatically assembled in a strict workstation sequence, avoiding the problems of incorrect or missing assembly that may be caused by manual operation. In particular, the terminal processing unit is fully automated in terms of clamping and cutting, insertion, strip breaking, and riveting and shaping. Combined with the horizontal swinging strip breaking design, it effectively eliminates the phenomenon of empty terminal installation, ensuring that the terminal is installed in place and the structure is stable.

[0039] Continuity testing and height testing not only verify the electrical performance of the terminals, but also ensure that the terminal installation dimensions are qualified through height testing. This avoids the potential for poor contact caused by traditional methods that only test continuity performance, and improves the overall yield.

[0040] The sorting robot automatically removes good products, while defective products are identified and retained by the testing unit, reducing errors and time costs associated with manual sorting. Attached Figure Description

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] Please see Figures 1-10 This embodiment of an automatic assembly machine for push connectors includes a multi-station rotary divider 1. Multiple carriers 2 for positioning push connector assemblies are fixedly mounted on the bearing surface of the divider 1. The carriers 2 intermittently move to each station as the divider 1 rotates. A component supply and assembly unit includes a first vibratory feeder 3 for supplying a plastic shell and a corresponding first gripping robot 4; a second vibratory feeder 5 for supplying a first button and a corresponding second gripping robot 6; a third vibratory feeder 7 for supplying a first spring and a corresponding third gripping robot 8; a fourth vibratory feeder 9 for supplying a second button and a corresponding fourth gripping robot 10; and a fifth vibratory feeder 11 for supplying a second spring and a corresponding fifth gripping robot. Robotic arms 12, including the first to fifth gripping robotic arms 4, 6, 8, 10, and 12, sequentially grip the corresponding parts and place them into designated holes in the plastic shell within the carrier 2 at a specific workstation, completing the installation of the buttons and springs. Multiple vibrating discs 3, 5, 7, 9, and 11, along with their corresponding gripping robotic arms 4, 6, 8, 10, and 12, are arranged sequentially around the multi-station rotary divider 1, corresponding to the workstations where each part is assembled in sequence. This arrangement achieves synchronization between the parts supply and assembly processes, ensuring that after the plastic shell is positioned, the buttons and springs are gripped by the robotic arms in a preset order and precisely assembled into the designated holes, reducing material handling paths and waiting time, and improving assembly efficiency.

[0058] Each carrier 2 includes a fixed base 201 and a placement base 202 fixedly connected to the divider 1. The upper surface of the placement base 202 is provided with a placement groove 2021 for placing a plastic shell. The fixed base 201 is provided with a pressing cylinder 2011 perpendicular to the upper surface of the divider 1 in the height direction. The output end of the pressing cylinder 2011 is fixedly connected to a pressing plate 2012 parallel to the upper surface of the divider 1 for fixing the plastic shell placed inside the placement groove 2021 to prevent displacement during the assembly of the first spring or the second spring.

[0059] Both the third gripping robot 8 and the fifth gripping robot 12 include a support frame 21. A rotary cylinder 211 is fixedly installed on the inner wall of the support frame 21. A flipping block 212 is fixedly connected to the output end of the rotary cylinder 211. A sealing protrusion 213 is provided on the surface of the flipping block 212. A limiting groove 214 adapted to the diameter of the external spring is opened on one side of the flipping block 212. The third vibrating plate 7 or the fifth vibrating plate 11, which is close to it, vibrates and conveys the first spring or the second horizontally arranged spring into the conveying track of the third vibrating plate 7 or the fifth vibrating plate 11 and into the interior of the limiting groove 214. When the flipping block 212 flips 90 degrees, the spring is vertically set at this time. At the same time, the sealing block blocks the conveying track, thereby preventing the subsequent arrangement of the first spring or the second spring from falling off the conveying track. The top of the support frame 21 is provided with a pneumatic slide rail 215 arranged radially with the divider 1. The pneumatic slide rail 215 extends along its length A transfer plate 216 is slidably connected in the direction of the first spring or the second spring. A vertically arranged first lifting cylinder 217 is installed on the surface of the transfer plate 216. A lifting block 218 is fixedly connected to the output end of the first lifting cylinder 217. A vertically arranged pin 219 is installed at the bottom end of the lifting block 218. A clamping cylinder 220 is installed on the surface of the lifting block 218. A clamping plate 221 is fixedly connected to the output end of the clamping cylinder 220. When the first spring or the second spring flips, the first lifting cylinder 217 drives the pin 219 to move downward and insert into the first spring or the second spring. Then, the clamping cylinder 220 drives the clamping plate 221 to enter the limiting groove 214 and slides to abut against the circumferential surface of the first spring or the second spring, thereby achieving the purpose of clamping the spring. Then, the first lifting cylinder 217 is reset and the first spring or the second spring is moved to the top of the divider 1 through the pneumatic slide rail 215, preparing the first spring or the second spring to be assembled with the plastic shell.

[0060] A button limiting mechanism 23 for limiting the first button or the second button is provided on one side of the support frame 21 near the divider 1. The button limiting mechanism 23 includes a second lifting cylinder 231. The output end of the second lifting cylinder 231 is fixedly connected to a button limiting frame 232. An inclined button limiting cylinder 233 is installed on the top of the button limiting frame 232. The output end of the button limiting cylinder 233 is fixedly connected to a button pressing rod 234. When the third gripping robot 8 or the fifth gripping robot 12 is preparing to assemble the first spring or the second spring, the pressing plate 2012 fixes the upper surface of the plastic shell to prevent it from shifting. The second lifting cylinder 231 drives the pressing cylinder 2011 to move upward. The first lifting cylinder 2011 outputs a button pressing rod 234, one end of which is inserted into the plastic shell and positioned above the installed first or second button. Then, the second lifting cylinder 231 moves downward to limit the first or second button, facilitating the installation of the first or second spring. After the first or second button is limited, the first lifting cylinder 217 drives the first or second spring to insert into the mounting hole of the plastic shell. At the same time, the clamping plate 221 separates from the first or second spring, completing the spring installation process. Finally, the third gripping robot 8 or the fifth gripping robot 12 resets, and the button limiting mechanism 23 resets, initiating the next first or second spring installation process.

[0061] The terminal processing unit includes a terminal tray 13 for continuously supplying terminals, a terminal clamping and cutting mechanism 14 for receiving terminal strips from the terminal tray 13, clamping individual terminals, and cutting them off at the connection point with the strip, a terminal insertion mechanism 15 for inserting the cut terminals into the plastic housing of the assembled components within the carrier 2, a terminal strip breaking mechanism 16 for swinging and breaking off the remaining strip connected to the terminals, and a terminal riveting and shaping mechanism 17 for performing secondary riveting and shaping on the inserted terminals. The terminal clamping and cutting mechanism 14, the terminal insertion mechanism 15, the terminal strip breaking mechanism 16, and the terminal riveting and shaping mechanism 17 are arranged sequentially around the multi-station rotary divider 1 after the component supply and assembly unit. Through the above arrangement, automatic cutting and riveting of terminals can be achieved. The terminal strip breaking mechanism 16 breaks off the remaining strip using a horizontal reciprocating swinging motion. Through the above arrangement, the phenomenon of empty terminals caused by incomplete strip cutting can be effectively prevented, thereby improving the yield.

[0062] The testing unit includes a continuity testing mechanism 18, which is used to test the electrical continuity performance of the internal terminals of the assembled connector. The terminal continuity testing mechanism 18 and the terminal height testing mechanism 19 are arranged sequentially around the multi-station rotary divider 1 after the terminal processing unit. With the above arrangement, automatic detection of the finished product can be achieved.

[0063] The height testing mechanism 19 is used to test whether the installation height of the assembly back end meets the requirements. The sorting unit includes a sorting robot 20, which is used to grab and remove the good products that have passed the test. The sorting robot 20 is located at the station after the testing unit. With the above settings, the automatic sorting and separation of finished products and defective products can be realized.

[0064] The working principle of the above embodiment is as follows: After the multi-station rotary divider 1 is powered on, the carrier 2 rotates with the divider to the initial station. After the first vibrating plate 3 vibrates and sorts the plastic shells, the first gripping robot 4 grips the shells and places them in the placement slot 2021 of the carrier 2. The divider 1 rotates to the next station. The second vibrating plate 5 supplies the first button. The second gripping robot 6 grips the button and inserts it into the corresponding hole in the plastic shell. The divider 1 continues to rotate. The third vibrating plate 7 delivers the first spring to the limiting slot 214 of the third gripping robot 8. The rotary cylinder 211 drives the flipping block 212 to flip 90°, making the spring vertical. The first lifting cylinder 217 drives the pin 219 to insert into the inner diameter of the spring and clamp it. Cylinder 220 drives clamping plate 221 to clamp the outer wall of the spring. Then, pneumatic slide rail 215 transfers the spring to the top of the plastic housing, inserts it into the designated hole, and releases it. Before insertion, pressing plate 2012 presses down to complete initial positioning, preventing displacement of the plastic housing. Simultaneously, second lifting cylinder 231 drives pressing cylinder 2011 to move upward. Pressing cylinder 2011 outputs button pressing rod 234, one end of which is inserted into the plastic housing and positioned above the installed first or second button. Then, second lifting cylinder 231 moves downward to limit the first or second button, facilitating the installation of the first or second spring. After the first or second button is limited, first lifting cylinder 217 drives the first... The spring or second spring is inserted into the mounting hole of the plastic shell, and at the same time, the clamping plate 221 separates from the first spring or the second spring, completing the spring installation process. The divider 1 rotates to the subsequent station. The fourth vibrating plate 9 and the fifth vibrating plate 11 sequentially supply the second button and the second spring. The four gripping manipulators 10 and 12 repeat the above steps to complete the installation of the symmetrical side button and the spring. The terminal material tray 13 releases the continuous terminal material strip to the terminal clamping and cutting mechanism 14. After the mechanism clamps a single terminal, it cuts off its connection point with the material strip, separating the independent terminal. The terminal insertion mechanism 15 inserts the cut terminal into the terminal hole of the plastic shell. The terminal material strip breaking mechanism 16 performs a horizontal reciprocating swing motion. The residual material strip connection is completely broken to prevent the terminals from sticking. The terminal riveting and shaping mechanism 17 performs a second stamping on the inserted terminals to ensure that the terminals are tightly bonded to the plastic shell and corrects the terminal's shape and size. The height testing mechanism 19 uses laser ranging to detect whether the exposed height of the terminals is within the tolerance range to ensure the matching accuracy with the docking socket. The sorting robot 20 grabs the good products that have passed the double test and transfers them to the finished product collection area. The connectors that have not passed the test are moved to the defective product box by the robot or directly rejected by the pneumatic device. The divider 1 continues to rotate to the initial station. The carrier 2 releases the assembled plastic shell base and enters the next cycle. All mechanisms are reset synchronously and wait for the next round of operation.
