Description

Technical Field

[0001] This application relates to the field of machining feeding and clamping technology, and in particular to a mechanical clamping device for injection molding of gearbox cover plates. Background Technology

[0002] The existing gearbox cover plate for new energy vehicles is made by one-piece injection molding. However, in the injection molding process of the gearbox cover plate mold, the shaft needs to be inserted into the injection mold in advance, and a sealing gasket also needs to be placed inside the gearbox cover plate. The shaft and the sealing gasket are placed in the corresponding injection mold cavity, and then the gearbox cover plate is formed by injection molding through the fixed template and the moving template.

[0003] In traditional gearbox cover injection molding production, the loading and assembly of components such as gaskets and shafts typically employ conventional methods. One common method is manual loading, where workers place the gaskets and shafts one by one into the mold cavity. While simple, this method is inefficient and prone to human error, affecting product quality stability. Another method involves controlling corresponding mechanical devices to place the shafts and gaskets into their respective injection molds. After injection molding, the molded gearbox cover is removed using a clamping device and sent to the next process. However, in actual production, multiple sets of mechanical devices are needed to place the corresponding shafts and gaskets into the injection molds. This process is time-consuming, and the multiple sets of devices also pose a risk of damage, causing delays in the entire production process and impacting efficiency.

The robotic arm clamping mechanism 3 first clamps the shaft pushed out by the second lifting rod through the first clamping part, and then rotates the operating plate 341 to align the sealing gasket feeding assembly 344 with the sealing gasket on the first feeding mechanism 1 and adsorb it. The entire robotic gripper 3 moves close to and extends into the injection molding machine. The suction cup assembly 342 on the robotic gripper 3 adheres to the molded product and attaches it to the suction cup. Simultaneously, the sealing gasket loading assembly 344 on the robotic gripper 3 moves close to the fixed mold plate and inserts the sealing gasket into the injection mold cavity. After insertion, the robotic gripper 3 moves towards the moving mold plate on the other side, inserting the shaft on the shaft clamping assembly 343 into the injection mold cavity within the moving mold plate, thus loading the shaft and sealing gasket. Finally, the robotic gripper 3 exits the injection molding machine and removes the molded product from the suction cup assembly 342. Through the coordinated movement of the first station 32, the second station 33, and the third station 34, the robotic gripper 3 achieves the clamping of the sealing gasket and shaft, and installs them into the mold cavity, completing the component assembly work in the injection molding production of the gearbox cover. It avoids the inefficiency and error-proneness of manual material feeding, improves the efficiency and quality of gearbox cover injection molding production, and effectively improves and enhances existing technology.

[0056] Reference Figure 6As shown, a third feeding mechanism 4 is also provided on the side of the first feeding mechanism 1. The third feeding mechanism 4 includes a third worktable 41, a positioning plate 42 installed on the third worktable 41 for placing the sealing gasket sticker, a third clamping assembly 43 arranged on both sides of the positioning plate 42 for clamping the sealing gasket sticker, a third sliding assembly 44 arranged on the third worktable 41, and a third adsorption assembly 45 arranged on the third sliding assembly 44 for separating the sealing gasket from the sealing gasket sticker.

[0057] The original sealing gasket was pasted onto a sealing gasket sticker and manually peeled off. However, this process often involved using fingernails, which could damage or scratch the gasket, affecting its sealing performance. Furthermore, this manual operation was time-consuming. The positioning plate 42 is mounted on the third workbench 41 and has several air holes 421. An internal suction unit is also installed on the positioning plate 42. When the sealing gasket sticker is placed on the positioning plate 42, a negative pressure is generated, adsorbing the gasket sticker and ensuring it adheres tightly to the plate. Simultaneously, a heating element is installed within the positioning plate 42 to preheat its surface to 30-40℃. This preheating melts the adhesive between the gasket and the sticker, facilitating subsequent removal of the gasket.

[0058] Reference Figure 6 and Figure 7 As shown, the third clamping assembly 43 includes a third telescopic component 431 mounted on the third worktable 41 and a third clamping component 432 arranged on the third telescopic component 431. The third telescopic component 431 is provided with a third telescopic motor and a third telescopic rod arranged on the third telescopic motor. The third telescopic rod is connected to the third clamping component 432. When the third telescopic motor is activated, the third clamping component 432 moves toward the positioning plate 42.

[0059] Reference Figure 7As shown, the third clamping component 432 is provided with a third clamping housing 4321. A third axial rack 4322 is disposed within the third clamping housing 4321, with a portion of the third axial rack 4322 protruding outside the third clamping housing 4321. A third driving gear 4323 is meshed on the third axial rack 4322, and a third driven gear 4325 is connected to the side of the third driving gear 4323, rotating together with the third driving gear 4323. A third longitudinal rack 4324 is meshed on the third driven gear 4325, protruding from the third clamping housing 4321. A third pressure plate 4326, also made of silicone, is disposed on the portion of the third longitudinal rack 4324 protruding from the third clamping housing 4321. Both the third axial rack 4322 and the third longitudinal rack 4324 are provided with third slide rails 4328 for sliding. Furthermore, a third elastic element 4327 is provided on the third axial rack 4322 and the third longitudinal rack 4324 for resetting the third axial rack 4322 and the third longitudinal rack 4324; preferably, the third elastic element 4327 can be a spring. Furthermore, bearings are provided on the third driving gear 4323 and the third driven gear 4325 to connect with the third fixed plate inside the third clamping housing 4321.

[0060] Reference Figure 8 As shown, when the third clamping component 432 approaches the positioning plate 42, the protruding end of the third axial rack 4322 abuts against the side of the positioning plate 42, causing the third axial rack 4322 to move towards the inside of the third clamping housing 4321, driving the third drive gear 4323 to rotate. Under the rotation of the third drive gear 4323, the third driven gear 4325 also rotates, causing the third longitudinal rack 4324 to also move towards the inside of the third clamping housing 4321, realizing the downward movement of the third pressure plate 4326 on the third longitudinal rack 4324. The third pressure plate 4326 falls onto the upper end of the positioning plate 42 and finally abuts against and clamps the sealing gasket sticker on the positioning plate 42. When released, the third clamping component 432 retracts under the action of the third telescopic component 431, the abutting force on the third axial rack 4322 decreases and becomes less than the elastic force generated by the third elastic element 4327, the third axial rack 4322 moves outward from the third clamping housing 4321 under the action of the third elastic element 4327, and controls the third driving gear 4323 to reverse, thereby causing the third driven gear 4325 to reverse and raise the third pressure plate 4326.

[0061] Reference Figure 6 and Figure 9As shown, the third sliding assembly 44 is equipped with a third gantry frame 441, and a lead screw assembly 442 is installed inside the third gantry frame 441. The horizontal sliding of the third adsorption assembly 45 is achieved by controlling the rotation of the lead screw through a motor. The third adsorption assembly 45 includes a third slider 451 and a third adsorption platform 452 arranged on the third slider 451. A circular third adsorption rod 453 is vertically arranged on the third adsorption platform 452, and a third pressure ring 454 is arranged around the third adsorption rod 453. The inner diameter of the third pressure ring 454 is larger than the outer diameter of the third adsorption rod 453, and the third adsorption rod 453 can move within the third pressure ring 454. At the same time, the diameter of the third adsorption rod 453 is smaller than the diameter of the sealing gasket, and the inner diameter of the third pressure plate 4326 is larger than the diameter of the sealing gasket. The third pressure ring 454 and the third adsorption rod 453 are each equipped with a cylinder for driving their respective movements. Preferably, the third adsorption rod 453 can be a vacuum adsorption rod, and a visual positioning sensor is provided on the third adsorption platform 452 to detect the working situation and send the detection signal to the control center unit, which then controls the entire process. After the sealing gasket is positioned, the third adsorption rod 453 falls onto the sealing gasket, and the third pressure ring 454 falls to surround the sealing gasket and abut against the sealing gasket sticker; after the third adsorption rod 453 adsorbs the sealing gasket, it rises, and the third pressure plate 4326 remains stationary and continues to abut against the sealing gasket sticker to facilitate the quick removal of the sealing gasket. The third pressure ring 454 then rises, completing the removal of the sealing gasket.

[0062] The implementation principle of this embodiment is as follows: By adding a third feeding mechanism 4, this mechanical clamping device can realize the feeding of the sealing gasket sticker and the separation of the sealing gasket, further improving the automation level and production efficiency of gearbox cover injection molding production. The sealing gasket sticker can be fed using existing suction cups or similar methods to place it on the positioning block 131. The third clamping component 43 moves to clamp the sealing gasket sticker on the positioning block 131, the third sliding component 44 enables the movement of the third adsorption component 45, and the sealing gasket sticker is removed via a visual positioning sensor. This makes the entire production process more complete and efficient, while reducing manual operation, lowering human error, and improving product quality.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
