[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 This utility model provides an embodiment of an automatic pin insertion dispensing machine, including a workbench 1 for supporting the overall equipment. A robotic arm 2 and a peristaltic dispensing machine 3 are arranged on the upper part of the workbench 1. The robotic arm 2 is used to grip the electronic product with pin insertion completed. The peristaltic dispensing machine 3 is an automated peristaltic dispensing machine 3, which can dispense glue to the electronic product with pin insertion completed according to the program. It is coordinated by a PLC controller. This technology is prior art, so it will not be described in detail. A conveying component 5 is arranged on the upper left side of the workbench 1 for conveying the product with pin insertion completed to the work position that the robotic arm 2 can grip. A connector seat 8 is arranged on the right side of the conveying component 5 for installing the product waiting to be installed with pins. A cylinder a4 is fixedly connected to the upper middle part of the workbench 1 for pushing the socket 69 to insert the pin into the inner wall of the product. A pin loading component 6 is arranged on the front side of the workbench 1 near the cylinder a4.
[0034] Reference Figure 1 and Figure 3 The needle assembly 6 includes a cylinder b61 for moving a push block 62. The cylinder b61 is fixedly connected to the upper part of the worktable 1. The push block 62 is fixedly connected to the left side of the output shaft of the cylinder b61 for driving the rotating part 63, the transmission wheel 65 and the servo motor c67 to move synchronously. A rotating shaft is provided on the front side of the push block 62 to provide support for the rotating part 63 and the transmission wheel 65. The rotating part 63 and the transmission wheel 65 are fixedly connected to the outer side of the rotating shaft. A clamping part 64 is provided on the rear side of the rotating part 63. The front side of the push block 62... A servo motor c67 is fixedly connected. Two sets of transmission wheels 65 are provided. The other set of transmission wheels 65 is fixedly connected to the left side of the output shaft of the servo motor c67. The two sets of transmission wheels 65 are connected by a synchronous belt 66. The rotation of the servo motor c67 drives one set of transmission wheels 65 to rotate, which causes the synchronous belt 66 to drive the transmission wheel 65 on the rotating shaft to rotate 180 degrees, thereby aligning the pin with the mounting groove in the middle of the socket 69. When the cylinder b61 extends or retracts, the pin held by the clamping member 64 is inserted into the mounting groove.
[0035] Reference Figure 3 and Figure 6The clamping member 64 includes a movable clamping plate 641, which is rotatably connected to the inner wall of the clamping member 64. The movable clamping plate 641 is elastically connected to the clamping member 64 via a torsion spring 642. A slot 643 is provided on the opposite side of the movable clamping plate 641 and the clamping member 64. The movable clamping plate 641 and the torsion spring 642 cooperate with the slot 643 to clamp the pin. It can adapt to different specifications of pins, provide stable clamping force, and avoid damage or loosening of the pin due to uneven force during manual operation. The elastic coefficient of the torsion spring 642 can keep the pin from falling off when moving. After the pin is inserted into the mounting groove in the middle of the socket 69, it still allows the pin to quickly fall off the slot 643 without affecting the pin. The pins need to be arranged by a vibration feeding device before feeding, which improves work efficiency.
[0036] The needle insertion assembly 6 also includes a socket 69 with a mounting groove on the left side, and the left side of the mounting groove is set as an inclined surface. The mounting groove is used to install the needle. The cylinder a4 drives the socket 69 to move and insert the needle into the product, thereby realizing automatic needle insertion. The socket 69 is fixedly connected to the left side of the output shaft of the cylinder a4. Guide rods are provided at the lower part of the cylinder a4 and the upper part of the cylinder b61. The socket 69 and the push block 62 slide on the outside of the guide rods provided at the lower part of the cylinder a4 and the outside of the cylinder b61 respectively through linear bearings. The guide rods are used to guide the socket 69 and the push block 62 to move stably and improve accuracy.
[0037] Two sets of contact sensors 68, model SJM-8, are fixedly connected to the front of the push block 62. They can be used in fields with extremely high precision requirements, such as precision mechanical positioning and electronic equipment manufacturing. The upper part of the contact sensor 68 is flush with the bottom of the rotating part 63. The servo motor c67 controlled by the contact sensor 68 can only drive the rotating part 63 to rotate 180 degrees for material feeding.
[0038] Reference Figure 2 , Figure 4 and Figure 5 The conveying component 5 includes a support base 51 fixedly connected to the upper part of the workbench 1, which supports the servo motor a52 and the lead screw 53. The servo motor a52 is fixedly connected to the front side of the support base 51 and rotates under the control of the PLC controller, driving the lead screw 53 to rotate, thereby controlling the moving part 54 to move between the pin mounting position and the work position of the robotic arm 2. The output shaft of the servo motor a52 is fixedly connected to the lead screw 53, which drives the moving part 54 to move stably. The moving part 54 is provided on the outside of the lead screw 53 through a threaded sleeve. The moving part 54 supports and rotatably connects to the driven wheel a55. The driven wheel a55 is used to drive the connector seat 8 to rotate. The inner wall of the driven wheel a55 is provided with a plug-in component 9, and the connector seat 8 is plugged into the inner wall of the plug-in component 9.
[0039] The lower part of the workbench 1 is equipped with a slide rail and a slider. The slider and the moving part 54 are fixedly connected. The fixed connection between the slider and the moving part 54 ensures that the servo motor b56 on the slider and the driven wheel a55 are always on the same vertical plane. The servo motor b56 is fixedly connected to the lower part of the slider. A mating wheel is set on the left side of the output shaft of the servo motor b56. The mating wheel and the driven wheel a55 are connected by a belt 57. The servo motor b56 drives the driven wheel a55 to rotate through the mating wheel and the belt 57. Under the control of the PLC controller, it rotates 120 degrees. By starting and stopping the servo motor b56 three times, the product can be rotated three times to insert pins.
[0040] Reference Figure 4 and Figure 5 The insertion assembly 9 includes a slot 91, which is located on the inner right side of the driven wheel a55 and is used to install the connector seat 8. The connector seat 8 is supported by a limiting groove 92. The inner wall of the slot 91 is provided with a sliding groove, and the inner wall of the sliding groove is provided with an elastic piece 93. The connector seat 8 is inserted into the inner wall of the sliding groove. The elastic piece 93 has a protrusion in the middle, which engages with the limiting groove 92 to ensure that the connector seat 8 is installed in place and to prevent loosening. At the same time, it enables quick positioning and fixing of the connector seat 8, adapting to the replacement needs of connector seats 8 of different specifications. The upper part of the moving part 54 is fixedly connected to a laser at the axial position of the driven wheel a55. Sensor 7, model optoNCDT5500 series, has its receiver located on the outside of the driven wheel a55, and there are three sets of them with an interval of 120 degrees. It can provide feedback on the rotation angle of the driven wheel a55 to the PLC controller. The PLC controller is located on the front of the upper part of the workbench 1. The PLC controller is a Huichuan PLC controller, which acts as the "brain" of the equipment. It coordinates and controls the collaborative operation of all components such as the transmission component 5, the needle insertion component 6, the cylinder a4, the cylinder b61, the peristaltic dispensing machine 3, and the robotic arm 2 to realize the full automation of the needle insertion, rotation, and dispensing process.
[0041] Working principle: When in use, the product to be processed is placed on the connector seat 8. The elastic sheet 93 of the plug assembly 9 is engaged with the limiting groove 92. The servo motor a52 drives the lead screw 53 to rotate, which drives the moving part 54 to transport the driven wheel a55 and the connector seat 8 along the slide rail to the left side of the needle insertion station cylinder a4 and move it to the rear side.
[0042] The clamping member 64 clamps the pin through the movable clamping plate 641 and the torsion spring 642 in conjunction with the slot 643. At this time, the servo motor c67 drives the rotating member 63 to rotate and press the contact sensor 68 through the transmission wheel 65 and the synchronous belt 66, ensuring that the rotation angle is accurate and only allows 180° rotation, so that the pin is aligned with the mounting slot of the socket 69.
[0043] The output shaft of cylinder b61 extends and retracts, causing the push block 62 to move to the right, so that the pin on the clamping member 64 is inserted into the inclined surface on the left side of the mounting slot of the socket 69. At this time, the servo motor c67 drives the rotating member 63 to rotate in the opposite direction through the transmission wheel 65 and the synchronous belt 66. The movable clamping plate 641 contacts the pin and squeezes the torsion spring 642, so that the movable clamping plate 641 is disengaged from the pin. Then, cylinder a4 pushes the socket 69 to move to the left along the guide rod, pressing the pin delivered by the clamping member 64 into the product in the connector seat 8.
[0044] After a single pin insertion is completed, the servo motor b56 drives the driven wheel a55 to rotate 120° via the belt 57. The PLC controls the start and stop three times to achieve three 120° rotations. After each rotation, the above pin insertion process is repeated to complete multi-directional pin insertion, such as three-position pin insertion. The laser sensor 7 monitors the rotation angle of the driven wheel a55 in real time. Every 120° rotation triggers the PLC controller to pause the motor, ensuring that the pin position accurately corresponds to the product hole position.
[0045] After the pin insertion is completed, the servo motor a52 drives the moving part 54 to move the driven wheel a55 and the product to the work station of the robotic arm 2. The robotic arm 2 picks up the product and moves it to the designated position below the peristaltic dispensing machine 3. The peristaltic dispensing machine 3 performs precise dispensing control on the product pin insertion part according to the PLC preset program, controlling the amount and trajectory of glue dispensing, and completing the entire process.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
