[0034] like Figures 1 to 3 As shown, a multi-mode intelligent pin preparation machine is arranged on the side of the injection molding device. After the prepared pins are inserted, they can be transferred by the injection molding machine robot arm for injection molding to form a connector. The present embodiment includes a machine base 1, a moving device provided on the end surface of the machine base 1 and a workbench 2 installed on the moving device. The moving device includes an X-axis moving mechanism 3 provided on the end surface of the machine base 1 and a Y-axis moving mechanism 4 provided on the X-axis moving mechanism 3. The workbench 2 is installed on the Y-axis moving mechanism 4 and can move along the X-axis and Y-axis. The workbench 2 includes a base 21, a connecting plate 22 rotatably installed on one end of the base 21, and a preparation plate 23 detachably fixedly connected to the connecting plate 22. A number of preparation parts 231 are provided on the preparation plate 23. An automatic discharging mechanism 6 and a pin insertion mechanism 5 for inserting the pins in the automatic discharging mechanism 6 into the preparation parts 231 are provided at one end of the Y-axis moving mechanism 4. A flipping mechanism 7 for driving the preparation plate 23 to flip vertically to dock with the injection molding machine robot arm is also provided on the base 21.
[0035] In this embodiment, an X-axis and Y-axis moving mechanism 4 is provided on the end face of the machine base 1. Both moving mechanisms are equipped with sensors, and the workbench 2 is fixed to the above-mentioned two moving mechanisms to ensure the precise positioning of the workbench 2 on the two-dimensional plane. The X-axis moving mechanism 3 slides horizontally along the end face of the machine base 1, while the Y-axis moving mechanism 4 moves vertically on it. The combination of the two ensures that the workbench 2 can flexibly reach the preset position, providing an accurate preparation layout for the insertion of different preparation parts 231 on the preparation plates 23 of different specifications. The workbench 2 is composed of a base 21, a connecting plate 22, and a preparation plate 23. It is firmly supported by the base 21 and the X-axis and Y-axis moving mechanisms 4. The preparation plate 23 is detachably fixed to the lower connecting plate 22 by bolts passing through multiple screw holes on the end face. When it is necessary to prepare for the insertion of pins for different molds, the original preparation plate 23 can be removed and replaced with a preparation plate 23 of the appropriate specification. The stock plate 23 is equipped with slots configured to specifications. These slots contain stock pieces 231 that coordinate with the pin insertion mechanism 5 to prepare the stock for pin insertion. The connecting plate 22 is pivotally connected to the base 21, and a reversible mechanism 7 is installed on the base 21. This mechanism drives the stock plate 23 to flip vertically, directly docking with the upper support portion of the injection molding machine's robotic arm, facilitating the removal of prepared pins from the stock plate 23. An automatic discharge mechanism 6 is located around the pin insertion mechanism 5 to automatically load the pins into the mechanism 5.
[0036] like Figure 2 and Figure 3As shown, in this embodiment, a rotating frame 8 is fixedly mounted on the base 21 at one end away from the pin insertion mechanism 5. A rotating shaft 81 is disposed within the rotating frame 8, and a connecting gear 82 is fixedly inserted through the rotating shaft 81. The top of the connecting gear 82 is rigidly connected to the bottom of the connecting plate 22. The connecting gear 82 is fixed to the connecting plate 22 and the connecting gear 82 is also fixed to the rotating shaft 81 within the rotating frame 8. The rotating shaft 81 can rotate within the rotating holes on both sides of the rotating frame 8, thereby driving the upper connecting plate 22 and the material preparation plate 23 to rotate, thereby achieving a rotational connection between the material preparation plate 23 and the base 21.
[0037] like Figure 2 and Figure 3 As shown, the flipping mechanism 7 of this embodiment includes a gear seat 71 arranged between the rotating frame 8 and meshing with the connecting gear 82, a guide rail 72 fixed to the bottom of the gear seat 71, a guide seat 73 fixed on the base 21 and slidably connected to the guide rail 72, and an X-axis pushing cylinder 74 arranged at one end of the gear seat 71, and the pushing rod in the X-axis pushing cylinder 74 is fixedly connected to the gear seat 71. The gear seat 71 is arranged between the rotating frames 8 and meshes with the connecting gear 82, and a guide rail 72 is fixedly provided at its bottom. A guide seat 73 is provided on the base 21, so that the gear seat 71 can slide along the guide seat 73 in the Y-axis direction, and a cylinder is provided on one side of the gear seat 71. The gas rod in the cylinder is fixed to the gear seat 71. When the gas rod contracts, it can drive the gear seat 71 to make linear motion along the guide rail 72 away from the connecting gear 82, and drive the meshing connecting gear 82 to rotate forward so that the upper preparation plate 23 can be flipped. A blank area is provided on the gear seat 71 to achieve flipping positioning, so that the preparation plate 23 is flipped to 90 degrees to dock with the robotic arm. Two positioning rods of the same length are provided on the end face of the base 21 to ensure that when the gas rod is extended to drive the preparation plate 23 to reset, the preparation plate 23 is limited to be parallel to the base 21 to prevent it from tilting and affecting the pins.
[0038] like Figure 3As shown, the base 21 of this embodiment is also equipped with a vacuum detection mechanism 9 for detecting whether the pins are correctly inserted. The vacuum detection mechanism 9 includes a vacuum pump 91 installed on the base 21, a vacuum tube 92 connected to the vacuum pump 91 at one end, and a vacuum hole 93 located at the bottom of the stock component 231. The other end of the vacuum tube 92 is equipped with several branch tubes 921, each of which is inserted into a vacuum hole 93. A solenoid valve 94 and a vacuum gauge 95 are also installed between the vacuum pump 91 and the vacuum tube 92. The vacuum tube 92 connects the vacuum pump 91, the solenoid valve 94, and the vacuum gauge 95. The other end of the vacuum tube 92 is equipped with a multi-way connector connecting the several branch tubes 921. In this embodiment, the stock component 231 on the stock component plate 23 is equipped with two branch tubes 921. Each branch tube 921 is inserted into the vacuum hole 93 at the bottom of the stock component 231. The vacuum hole 93 is connected to the pin hole on the stock component 231 for inserting pins. The solenoid valve 94 opens and the vacuum pump 91 is started to extract the air from the hole. When the pin is fully inserted in the correct position, a closed space is formed inside the hole, which will not affect the original vacuum state. However, if the pin is not inserted correctly or not fully inserted, the inside and outside of the hole are connected through the gap between the pin and the hole, resulting in a decrease in the vacuum level. Keep the vacuum pump 91 pumping air and observe the reading of the vacuum gauge 95. If the vacuum level remains stable or close to the high level before evacuation, it indicates that the pin is correctly positioned and a good seal has been formed. If the vacuum level drops significantly, it indicates a leak, that is, the pin may not be inserted correctly or there is other leakage.
[0039] like Figure 1 and Figure 3 As shown, the X-axis motion mechanism 3 of this embodiment includes two X-axis rails 31 mounted parallel to the end surface of the base 1, an X-axis sliding base 32 slidably connected to the two X-axis rails 31, and a first drive motor 33 located at one end of the X-axis rails 31 for driving the X-axis sliding base 32. The two X-axis rails 31 are mounted parallel to the end surface of the base 1. The sliding base is driven to slide with the X-axis rails 31 via built-in ball bearings and driven by the first drive motor 33. The sliding base may be equipped with positioning pins or sensors to ensure accurate positioning and feedback control during movement. The Y-axis motion mechanism 4 includes a Y-axis rail 41 fixed to the X-axis sliding base 32, a Y-axis sliding base slidably connected to the Y-axis rail 41, and a second drive motor 42 located at one end of the Y-axis rail 41 for driving the Y-axis sliding base; a Y-axis sliding base 43; and a base 21 fixed to the Y-axis sliding base. The Y-axis motion mechanism 4 is provided on the X-axis motion mechanism 3, enabling the worktable 2 to move freely in two dimensions. The X-axis is responsible for horizontal movement, while the Y-axis is responsible for vertical movement. The dual-axis linkage design enables the preparation plate 23 to cover every corner on the end face of the machine base 1, adapting to the diverse preparation position requirements and improving the applicability and flexibility of the equipment.
[0040] like Figure 1 and Figure 4As shown, the pin insertion mechanism 5 of this embodiment includes a gantry 51 mounted on the Y-axis slide rail 41, a Z-axis push cylinder 52 located on the side of the gantry 51 near the workbench 2, a fixed plate 53 connected to the push rod in the Z-axis push cylinder 52, and a pin air clamp 54 located at the bottom of the fixed plate 53 and connected to the automatic discharge mechanism 6. The automatic discharge mechanism 6 includes a vibrating plate 61 mounted on the end surface of the machine base 1 and a discharge blowpipe 62 connected to the outlet end of the vibrating plate 61. The other end of the discharge blowpipe 62 is inserted into the pin air clamp 54. The automatic discharge mechanism 6 specifically includes two vibrating plates 61, each containing two different pins, and two fixed plates 53 are also provided on the left and right sides. The vibrating plates automatically arrange the pins in an orderly manner, while the discharge blowpipe 62 is driven by an external air source and uses compressed air to blow the pins one by one into the pin air clamp 54 for insertion. Specifically, two pin air clamps 54 are connected in an upper and lower manner, one of which is connected to the automatic discharge mechanism 6, and the other air clamp can smoothly insert the pin into the spare part 231 under the control of the Z-axis push cylinder 52.
[0041] In summary, the beneficial effects of this embodiment are as follows: This embodiment achieves precise movement and positioning of the workbench 2 on a two-dimensional plane by combining the use of sensors through the X-axis and Y-axis moving mechanisms 4, ensuring the accuracy of the stocking operation, being suitable for stocking plates 23 and stocking parts 231 of various specifications, and improving production efficiency and flexibility. The stocking plate 23 adopts a detachable fixed connection design, which can quickly replace stocking plates 23 of different specifications to meet different production needs. The integrated automatic discharge mechanism 6 works in conjunction with the pin insertion mechanism 5 to achieve a fully automated process from pin sorting to precise insertion of stocking parts 231, reducing manual intervention and improving production efficiency. The flip mechanism 7 between the stocking plate 23 and the base 21 can drive the stocking plate 23 to flip vertically to conveniently dock with the injection molding machine robot arm. The vacuum detection mechanism 9 set on the base 21 can instantly detect the correctness of the pin insertion, ensuring that the pins of each stocking part 231 are assembled correctly.
[0042] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
