Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector pin insertion device for terminal group assembly. Background Art

[0002] In the electronic manufacturing industry, as a key component for signal and power transmission between electronic devices, the performance and cost-effectiveness of connectors directly affect the market competitiveness of the overall product. The traditional manufacturing method for the terminal group of the connector housing mainly adopts the integrated strip integral stamping forming technology. Although this technology ensures the structural integrity and assembly accuracy of the terminal group to a certain extent, the integral strip stamping forming technology has the following deficiencies: First, the process complexity is high, involving multiple links such as mold design, material selection, and stamping parameter optimization. It has high requirements for production equipment and the skills of operators. And the complex process flow leads to a long production cycle and a high error rate. Once a problem occurs in a certain link, it may cause the entire batch of products to be scrapped, resulting in huge economic losses. Second, the utilization rate of process materials is low. Since it is necessary to ensure the integrity and strength of the terminal group, additional material support structures often need to be added in the design. These structures may not directly participate in the function realization in the final product, thus causing material waste and resulting in a higher product cost.

[0003] Therefore, in order to solve the deficiencies of the integral strip stamping forming technology, a manufacturing process method of first separating and manufacturing the connector terminal pins from the integral terminal group is adopted. This manufacturing method not only simplifies the forming process, reduces the production difficulty and error rate, but also significantly improves the material utilization rate. By accurately calculating the size and shape of each terminal, unnecessary material waste can be minimized, thereby reducing production costs. However, the separated design also brings new challenges, that is, how to achieve precise, efficient, and automated assembly between the connector terminal pins and the terminal group. Currently, the assembly of the connector terminal pins and the integral terminal group usually requires manual operation, with low work efficiency and high production costs, and there is a lack of equipment with functions such as high-precision positioning, rapid grasping, and stable insertion into the terminal group. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connector pin insertion device for terminal group assembly to solve the problem that when the existing technology adopts the manufacturing process of separating and manufacturing the connector terminal pins from the integral terminal group, there is a lack of high-precision, fast, and stable automated assembly equipment, resulting in low assembly efficiency and high costs.

[0020] According to the above technical means, the first driving device drives the second rotating shaft to rotate, driving the rotating plate to rotate, thereby driving the connector pins clamped on the clamping structure to rotate synchronously, achieving a smooth transition of the connector pins from a horizontal state to a vertical state. And under the action of the first positioning groove, the stable positioning of the connector pins is ensured, avoiding the risk of deviation or dropping during the clamping process; during operation, after the first controller controls the first robotic arm to move the connector pins on the bulk material tray to the first positioning groove on the fixed plate through the needle picking suction cup, one end of the connector pin is limited in the first positioning groove, and the other end is located at the clamping end of the clamping structure.

During operation, the first pressing plate abuts against the fixed plate to make the second positioning groove communicate with the first positioning groove. The first air cylinder drives the second pressing plate away from the first pressing plate to open the clamping end. The needle picking suction cup transports the connector pins on the bulk material tray to the rotating assembly, so that one end of the connector pin is located in the first positioning groove and the other end is located in the second positioning groove.

[0045] The technical solutions of the present utility model will be described in detail below with reference to specific drawings.

[0046] This embodiment relates to a connector pin insertion device for terminal group assembly, as Figures 1-4 shown, comprising: a base 1 and a bulk material tray 2, the bulk material tray 2 is installed on the base 1, and a plurality of connector pins 3 are horizontally placed on the bulk material tray 2; a coordinate detection device 4, a first transfer assembly 5 and a rotation assembly 6, the coordinate detection device 4, the first transfer assembly 5 and the rotation assembly 6 are all installed on the base 1, and the coordinate detection device 4 is communicatively connected to the first transfer assembly 5; the coordinate detection device 4 is used to detect the coordinates of each connector pin 3 on the bulk material tray 2, the first transfer assembly 5 is configured to move the connector pin 3 to the rotation assembly 6 according to the coordinates detected by the coordinate detection device 4, and the rotation assembly 6 is used to rotate the connector pin 3 from a horizontal state to a vertical state; a second transfer assembly 7, the second transfer assembly 7 is installed on the base 1 and is used to move the connector pin 3 rotated by the rotation assembly 6 to the assembly station 8 of the terminal group.

[0047] In this embodiment, through functions such as the integrated coordinate detection of the connector pins 3 by the coordinate detection device 4, the precise transfer of the first transfer assembly 5, the rotation of the direction of the connector pins by the rotation assembly 6, and the transfer and pin insertion of the second transfer assembly 7, the efficient, stable and automated transfer of the connector pins 3 from the bulk material tray 2 to the assembly station 8 of the terminal group is realized, and the assembly accuracy is high, ensuring the accurate docking of the connector pins 3 with the terminal group, improving the production efficiency, reducing the manual operation cost and error rate, and enhancing the product quality;

[0048] During specific operation, first, a number of connector pins 3 are scattered on the bulk material tray 2. Each connector pin 3 is in a horizontal state on the bulk material tray 2. The coordinate detection device 4 accurately identifies the coordinate positions of each connector pin 3 on the bulk material tray 2 and transmits the coordinate information to the first transfer assembly 5. Subsequently, the first transfer assembly 5 accurately grabs and moves the connector pin 3 in the horizontal state from the bulk material tray 2 to the rotating assembly 6 according to the received coordinate information. Then, the rotating assembly 6 rotates the connector pin 3 from the horizontal state to the vertical state to meet the assembly requirements of the terminal group and improve the assembly efficiency. Then, the second transfer assembly 7 accurately moves the rotated connector pin 3 to the assembly station 8 of the terminal group to directly insert the connector pin 3 in the vertical state into the terminal group, completing the entire insertion process. Finally, the connector pin 3 and the terminal group are firmly connected by means of die pressing to realize the assembly and forming combination of the terminal group. The utility model realizes the efficient and automatic assembly of the connector pin 3, significantly improves the assembly accuracy and production efficiency, reduces the manual operation cost, and provides the key technology for the process of separately designing and manufacturing the connector pin 3 and the overall terminal group.

[0049] In this embodiment, a vibration device 9 is further included. The vibration device 9 is installed on the base 1, and the bulk material tray 2 is installed on the vibration device 9. The vibration device 9 is used to drive the bulk material tray 2 to vibrate so as to disperse the connector pins 3 on the bulk material tray 2. As Figure 1 shown, during operation, the vibration device 9 drives the periodic mechanical vibration of the bulk material tray 2, prompting the connector pins 3 on the bulk material tray 2 to disperse, avoiding the stacking and adhesion of the connector pins 3, improving the detection accuracy of the coordinate detection device 4, because the dispersed connector pins 3 are easier to be accurately positioned. At the same time, the dispersed connector pins 3 are easier to be grabbed and transferred by the first transfer assembly 5, ensuring the smooth progress of the terminal group assembly.

[0050] In this embodiment, the coordinate detection device 4 includes a bracket 41 and a vision detection device 42. The bracket 41 is installed on the base 1, and the vision detection device 42 is installed on the bracket 41 and located directly above the bulk material tray 2. The vision detection device 42 is used to detect the coordinates of each connector pin 3 on the bulk material tray 2, and the vision detection device 42 is communicatively connected to the first transfer assembly 5.

[0051] As Figure 1 and Figure 2As shown in the figure, in this embodiment, the vision inspection device 42 is stably installed directly above the bulk material tray 2 through the bracket 41, ensuring that the vision inspection device 42 can accurately align with the bulk material tray 2, take pictures and perform image recognition, so as to quickly, accurately and non-contact detect the coordinate positions of each connector pin 3 on the bulk material tray 2. At the same time, the length direction of each connector pin 3 can also be detected. During specific operation, the first transfer assembly 5 realizes the fast and precise transfer of the connector pins 3 according to the detection results of the vision inspection device 42, improving the work efficiency and quality.

[0052] In this embodiment, the first transfer assembly 5 includes a first robotic arm 51, a needle picking suction cup 52 and a first controller. The first robotic arm 51 is installed on the base 1, and the needle picking suction cup 52 is installed on the first robotic arm 51 for adsorbing or releasing the connector pins 3. The first robotic arm 51 and the needle picking suction cup 52 are respectively connected to the first controller for control. The first controller is communicatively connected to the vision inspection device 42. The first controller is configured to control the first robotic arm 51 to drive the needle picking suction cup 52 to move according to the coordinates detected by the coordinate detection device 4, so as to move the connector pins 3 on the bulk material tray 2 to the rotating assembly 6.

[0053] As Figure 2 and Figure 3 shown, during specific operation of this embodiment, when the vision inspection device 42 detects the accurate coordinates of each connector pin 3 on the bulk material tray 2, these coordinate information are immediately transmitted to the first controller. The first controller accurately controls the movement trajectory of the first robotic arm 51 according to the received coordinate information, thereby driving the needle picking suction cup 52 to move between the bulk material tray 2 and the rotating assembly 6. And during this stroke, the first controller will also control the needle picking suction cup 52 to adsorb or release the connector pins 3 according to the real-time situation. Thus, the connector pins 3 are accurately and quickly transferred from the bulk material tray 2 to the rotating assembly 6, improving the transfer efficiency and accuracy and reducing manual intervention. Among them, the first robotic arm 51 can be a four-axis robot, and the needle picking suction cup 52 can be a vacuum suction cup.

[0054] In this embodiment, the first transfer assembly 5 further includes a first rotating shaft 53. One end of the first rotating shaft 53 is rotatably installed on the first robotic arm 51, and the needle picking suction cup 52 is installed at the other end of the first rotating shaft 53. The first rotating shaft 53 is connected to the first controller for control. The first controller is further configured to control the first rotating shaft 53 to drive the needle picking suction cup 52 to rotate according to the coordinates detected by the coordinate detection device 4, so that each connector pin 3 on the bulk material tray 2 can be moved to the rotating assembly 6 along the same length direction.

[0055] As Figure 3As shown in the figure, when the vision detection device 42 in this embodiment takes pictures of each connector pin 3 on the bulk material tray 2 and performs image recognition, it not only detects the coordinate information of each connector pin 3 on the bulk material tray 2, but also detects the length direction information of each connector pin 3. During specific operation, after the vision detection device 42 completes the detection of the connector pins 3, the first controller not only controls the movement of the first robotic arm 51, but also adjusts the rotation angle of the first rotating shaft 53 according to the length information after the needle picking suction cup 52 adsorbs the connector pin 3, so that the connector pin 3 can move to the rotating assembly 6 according to the preset angle and direction, and ensures that all connector pins 3 are arranged along the same length direction, improving the efficiency of the overall production line and the consistency of products, and further enhancing the flexibility and accuracy of automated production.

[0056] In this embodiment, the rotating assembly 6 includes a rotating plate 61, a fixing plate 62 and a first driving device 63. One end of the rotating plate 61 is fixed with a second rotating shaft 611, and a clamping structure 64 is installed at the other end. The fixing plate 62 is fixed on the base 1. A first positioning groove 621 is formed on the fixing plate 62. The length of the first positioning groove 621 is arranged in the horizontal direction and is perpendicular to the second rotating shaft 611. The clamping end of the clamping structure 64 can communicate with the first positioning groove 621, so that one end of the connector pin 3 is located in the first positioning groove 621 and the other end is located at the clamping end of the clamping structure 64. The second rotating shaft 611 is rotatably installed on the base 1. The first driving device 63 is connected to the second rotating shaft 611 and is used to drive the second rotating shaft 611 to drive the rotating plate 61 to rotate, so that the connector pin 3 clamped by the clamping end of the clamping structure 64 rotates from the horizontal state to the vertical state.

[0057] As Figures 4-7 shown in the figure, this embodiment can convert the connector pin 3 from the horizontal state to the vertical state, so that the connector pin 3 after the direction conversion can be directly inserted into the terminal group, facilitating the quick and stable completion of the assembly combination. During specific operation, the first controller controls the first robotic arm 51 to drive the needle picking suction cup 52 to move the connector pin 3 into the first positioning groove 621, so that one end of the connector pin 3 is firmly placed in the first positioning groove 621 and the other end is clamped by the clamping structure 64 to ensure that the position and direction of the connector pin 3 are in a stable state. Then, the first driving device 63 drives the second rotating shaft 611 to drive the rotation of the rotating plate 61, so that the clamping structure 64 drives the connector pin 3 to gradually rotate from the horizontal state to the vertical state, laying a foundation for the quick and stable insertion of the connector pin 3 into the terminal group. Among them, as a preferred implementation method, the number of the first positioning grooves 621 can be two or more, and each first positioning groove 621 is evenly distributed along the length direction of the second rotating shaft 611, so that it can be adjusted according to the actual demand for the number of connector pins 3 to quickly complete the assembly combination of the terminal group, with high flexibility and strong practicability.

[0058] In this embodiment, the clamping structure 64 includes a first pressing plate 641, a second pressing plate 642, and a first air cylinder 643. The first pressing plate 641 is fixed on the rotating plate 61. A second positioning groove 6411 is formed on the first pressing plate 641. The second positioning groove 6411 is perpendicular to the second rotating shaft 611 and can communicate with the first positioning groove 621, so that one end of the connector pin 3 is located in the first positioning groove 621 and the other end is located in the second positioning groove 6411. The second pressing plate 642 is movably installed on the rotating plate 61 and can abut against the first pressing plate 641 to clamp the connector pin 3. The first air cylinder 643 is installed on the rotating plate 61 and is connected to the second pressing plate 642. The first air cylinder 643 is used to drive the second pressing plate 642 to act, so that the clamping end opens and closes.

[0059] As Figure 4 , Figure 5 and Figure 7 shown, the number of the second positioning grooves 6411 in this embodiment is the same as that of the first positioning grooves 621 and they correspond to each other one by one. During specific operation, when the first controller controls the first robotic arm 51 to drive the needle picking suction cup 52 to transfer the connector pin 3, the second pressing plate 642 moves away from the first pressing plate 641 to open the clamping end. At the same time, the first pressing plate 641 abuts against the fixing plate 62, so that the second positioning groove 6411 communicates with the first positioning groove 621, ensuring that the needle picking suction cup 52 releases the connector pin 3 so that one end is located in the first positioning groove 621 and the other end is located in the second positioning groove 6411. Subsequently, the first air cylinder 643 drives the second pressing plate 642 to move towards the first pressing plate 641 until they abut against each other, thereby realizing firm clamping of the connector pin 3. When the rotating plate 61 rotates, the clamped connector pin 3 is driven to rotate synchronously, improving production efficiency.

[0060] In this embodiment, the first driving device 63 includes a gear 631, a rack 632, and a second air cylinder 633. The gear 631 is installed on the second rotating shaft 611. The gear 631 meshes with the rack 632. The second air cylinder 633 is installed on the base 1. The second air cylinder 633 is connected to the rack 632.

[0061] As Figure 6 shown, during specific operation of this embodiment, the second air cylinder 633 drives the rack 632 to move linearly, thereby driving the gear 631 to drive the second rotating shaft 611 to perform a circular motion, so as to drive the rotating plate 61 to rotate and realize the direction switching of the connector pin 3. The transmission structure is simple and the transmission efficiency is high, making the entire driving process smoother and more reliable.

[0062] In this embodiment, the second transfer assembly 7 includes a second robotic arm 71 and a gripper 72. The second robotic arm 71 is mounted on the base 1, and the gripper 72 is mounted on the second robotic arm 71 for clamping or releasing the connector pins 3. The second robotic arm 71 is used to drive the gripper 72 to move, so as to move the connector pins 3 after the rotation of the clamping structure 64 to the assembly station 8 of the terminal group.

[0063] As Figure 1 and Figure 2 shown, in this embodiment, the second robotic arm 71 drives the gripper 72 to move, so as to transfer the connector pins 3 after the rotation direction to the assembly station 8 of the terminal group and directly insert the connector pins 3 into the terminal group, so as to accelerate the assembly combination of the connector pins 3 and the terminal group. During specific operation, when the clamping structure 64 completes the rotation of the connector pins 3, the second robotic arm 71 drives the gripper 72 to accurately move above the connector pins 3. Then the gripper 72 performs a clamping action to firmly clamp the connector pins 3. Then the second robotic arm 71 moves again to smoothly move the connector pins 3 to the assembly station 8. Finally, the connector pins 3 are directly inserted into the terminal group by means of die pressing to complete the assembly combination, improving the efficiency and accuracy of the transfer of the connector pins; wherein, the gripper 72 can be composed of two clamping blocks. The two clamping blocks are respectively movably mounted on the second robotic arm 71 and are connected with a power source (such as a cylinder or a motor, which is used to drive the clamping blocks to move towards or away from each other to realize the functions of clamping or releasing), and a limiting groove adapted to the connector pins 3 is formed in the vertical direction on the opposite surface of one of the clamping blocks. The number of the limiting grooves is the same as and corresponds to the number of the second positioning grooves 6411 one by one, so as to prevent the connector pins 3 from shifting or falling during the process of clamping the connector pins 3.

[0064] In this embodiment, the second transfer assembly 7 further includes a defective product detection device 73 and a second controller. The defective product detection device 73 is mounted on the base 1 and is used to detect whether the connector pins 3 rotated on the clamping structure 64 meet the assembly standards. The defective product detection device 73, the second robotic arm 71 and the gripper 72 are respectively communicatively connected with the second controller. The second controller is configured to control the second robotic arm 71 to drive the gripper 72 to move according to the detection result of the defective product detection device 73, so as to move the rotated connector pins 3 to the assembly station 8 of the terminal group or into the defective product box.

[0065] As Figure 1 and Figure 2As shown in the figure, during the actual operation of this embodiment, after the direction of the connector pin 3 is adjusted by the rotation assembly 6, the defective product detection device 73 will conduct strict quality inspection on it to ensure that each connector pin 3 meets the assembly standard. The inspection results will be transmitted to the second controller immediately. For the qualified connector pins 3, the second controller controls the second robotic arm 71 to drive the gripper 72 to accurately move it to the assembly station 8 of the terminal group for subsequent assembly use; while for the unqualified products, the second controller controls the second robotic arm 71 to drive the gripper 72 to transfer them into the defective product box to prevent them from entering the production process and causing unnecessary waste or quality problems. Among them, the defective product detection device 73 can also be a visual detection device that conducts detection by taking pictures and recognition.
