Detailed Implementation

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 7 As shown in the figure, the latch 1 provided in this embodiment of the utility model is an important component of the car door lock. Injection molding of the latch 1 is an important process in the manufacturing process of the latch 1. The injection molding process can produce latches 1 with complex shapes to meet the design requirements of different car door locks. The shape and size of the latch 1 can be precisely shaped according to the specific structure and functional requirements of the door lock to ensure perfect cooperation with other components of the door lock.

[0029] An automatic clamping and feeding device for locking tongues is mainly used in the injection molding process (not limited to other processing stages) for feeding materials into an injection molding machine 7. The locking tongue 1 has a sheet-like structure and two through holes 11. The clamping and feeding device mainly includes a worktable 2, a first platform 3, a second platform 4, a first multi-axis robotic arm 5, and a second multi-axis robotic arm 6. A vibrating feeding plate 21 is installed on the worktable 2. The output end of the vibrating feeding plate 21 is connected to a discharge groove 22. The vibrating feeding plate 21 is prior art, and its principle will not be elaborated in detail here.

[0030] The first platform 3 is disposed above the workbench 2. The upper end of the first platform 3 is provided with a first slot 31 that matches the shape of the latch 1. At least one side of the first slot 31 penetrates the first platform 3 to form an opening 311. The tail end of the unloading groove 22 is directly opposite the opening 311, and the bottom end of the unloading groove 22 is on the same plane as the bottom of the first slot 31. The second platform 4 is disposed above the workbench 2. The upper end of the second platform 4 is provided with at least two second slots 41 that match the shape of the latch 1. Each second slot 41 has two positioning parts 42. In some practical applications, the two positioning parts 42 are configured as longitudinally arranged positioning pins, and the top of the positioning pins is configured as a cone. The cone design makes it easy for the through hole 11 of the latch 1 to fit into the corresponding positioning pin to achieve positioning.

[0031] The first multi-axis robotic arm 5 is equipped with a first adsorption source at its execution end. The first adsorption source adsorbs the locking tongue 1 in the first slot 31 and transfers it to the second slot 41. The locking tongue 1 is at least partially submerged in the second slot 41 to achieve axial positioning of the locking tongue 1. Two positioning parts 42 are coaxially inserted into the two positioning holes of the locking tongue 1 to achieve lateral positioning of the locking tongue 1. The second multi-axis robotic arm 6 is equipped with a second adsorption source at its execution end. The second adsorption source has adsorption ends 61 corresponding to the number of second slots 41 to adsorb locking tongues 1 in multiple second slots 41.

[0032] In actual operation, the vibrating feeder 21 works to arrange the sheet-like locking tongues 1 in an orderly manner and transport them to the unloading chute 22. The vibrating feeder 21 causes the locking tongues 1 to move along a specific track through its own vibration, and finally output from the unloading chute 22. Since the tail end of the unloading chute 22 is directly opposite the opening 311 of the first slot 31 of the first platform 3, and the bottom end of the unloading chute 22 is on the same plane as the bottom of the first slot 31, the locking tongues 1 smoothly slide from the unloading chute 22 into the first slot 31 of the first platform 3, and the shape of the first slot 31 is adapted to the locking tongues 1.

[0033] The first multi-axis robotic arm 5 is activated, and its first adsorption source at the actuator end adsorbs the locking tongue 1 located in the first slot 31. Then, the first multi-axis robotic arm 5 transfers the locking tongue 1 to the second slot 41 of the second platform 4. The locking tongue 1 is at least partially submerged in the second slot 41, achieving axial positioning. Simultaneously, two positioning parts 42 within the second slot 41 are coaxially inserted into the two positioning holes of the locking tongue 1, completing the lateral positioning of the locking tongue 1. Then, the second multi-axis robotic arm 6 begins operation. Its second adsorption source at the actuator end has adsorption ends 61 corresponding to the number of second slots 41. These adsorption ends 61 simultaneously adsorb multiple locking tongues 1 that have been positioned in the second slots 41. Next, the second multi-axis robotic arm 6 transports the locking tongue 1 to the injection molding machine 7 for injection molding.

[0034] Therefore, in this embodiment, the entire device, through the cooperation of components such as the vibrating feeding plate 21 and the multi-axis robotic arm, realizes the automatic gripping and feeding process of the locking tongue 1, reducing manual intervention and improving production efficiency. For automated production, the second slot 41 of the second platform 4 and its internal positioning part 42 can perform axial and lateral positioning of the locking tongue 1, ensuring that the locking tongue 1 is in an accurate position before entering the injection molding machine 7, which is beneficial to improving the precision of injection molding. Furthermore, the second adsorption source of the second multi-axis robotic arm 6 has multiple adsorption ends 61, which can simultaneously adsorb multiple locking tongues 1 in multiple second slots 41, achieving batch feeding.

[0035] This device can be used in the injection molding process, and is not limited to other processing stages, thus possessing a certain degree of versatility and adapting to different production needs. Furthermore, it uses an adsorption method to grip the locking tongue 1, which reduces damage to the surface of the locking tongue 1 compared to traditional mechanical gripping methods.

[0036] In some practical applications, refer to Figures 3 to 6 As shown, the first adsorption source is configured as a first pneumatic suction cup 51, with the output end of the first pneumatic suction cup 51 pointing downwards. The second adsorption source is configured as a tilting cylinder 62 mounted on the execution end of the second multi-axis robotic arm 6, and a second pneumatic suction cup 63 mounted on the execution end of the tilting cylinder 62 and capable of switching between a first position and a second position. The second pneumatic suction cup 63 has several suction ports, i.e., adsorption ends 61. In the first position, the tilting cylinder 62 is in the initial position, and the second pneumatic suction cup 63 is in a horizontal state. In the second position, the tilting cylinder 62 is in the active position, and the second pneumatic suction cup 63 is in a vertical state.

[0037] Based on the previous steps, after the first pneumatic suction cup 51 (first adsorption source) of the first multi-axis robotic arm 5 transfers the locking tongue 1 from the first platform 3 to the second platform 4 to complete the positioning, the second multi-axis robotic arm 6 begins the subsequent operation: initially, the flipping cylinder 62 is in the initial position (first position), the second pneumatic suction cup 63 is in a horizontal state, and its air intake (adsorption end 61) is aligned with the locking tongue 1 that has been positioned in the second slot 41, and the adsorption function is activated to adsorb multiple locking tongues 1.

[0038] Next, the second multi-axis robotic arm 6 moves upward a certain distance, and the tilting cylinder 62 actuates, transitioning from the initial position to the operating position (second position). At this time, the second pneumatic suction cup 63 becomes vertical. When used for loading injection molds, the vertical position is compatible with horizontally arranged injection molds, facilitating the second multi-axis robotic arm 6 to accurately place the suction latch 1 into the injection mold, completing the loading process. When dealing with different types of molds or other processing flows, the state of the second pneumatic suction cup 63 can be adjusted according to actual needs, making the device more versatile.

[0039] In some practical applications, refer to Figure 3 , Figure 4 and Figure 6 As shown, the vibrating feeding tray 21 is configured in two sets, and the first slot 31 on the first platform 3 is also configured in two sets. The unloading grooves 22 on the two sets of vibrating feeding trays 21 correspond to the two first slots 31 respectively. The second slot 41 on the second platform 4 is configured in four sets. The two sets of vibrating feeding trays 21 and the two sets of first slots 31 work simultaneously, which can handle more locking tongue 1 feeding tasks in parallel. The second platform 4 is configured with four sets of second slots 41, which can accommodate more locking tongues 1 transferred from the first platform 3. Therefore, the second multi-axis robotic arm 6 can pick up four locking tongues 1 at one time for feeding, and the injection molding of four sets of locking tongues 1 can be completed in one molding process in the mold.

[0040] In some practical applications, the first platform 3 is slidably connected to the slide rail 32, and the first platform 3 is driven by the linear cylinder 33 to move on the slide rail 32, so that the opening 311 of the first slot 31 is aligned with the corresponding unloading slot 22. The worktable 2 is provided with a lifting source 34, and the slide rail 32 is installed on the execution end of the lifting source 34.

[0041] The first platform 3 can move along the slide rail 32 under the drive of the linear cylinder 33, which can precisely adjust the relative position of the first slot 31 and the unloading slot 22, ensuring that the conveying of the locking tongue 1 from the unloading slot 22 to the first slot 31 is more accurate. By adjusting the height of the slide rail 32 and the first platform 3 through the lifting source 34, it can adapt to the vibrating loading plate 21 and unloading slot 22 of different height specifications, enhancing the adaptability of the device to different equipment and production environments.

[0042] Based on the above description, when this clamping and feeding device is applied to the injection molding of latches 1, the clamping and feeding device is located beside the injection molding machine 7. The second pneumatic suction cup 63 adsorbs multiple latches 1 and is fed into the injection mold cavity of the injection molding machine 7 by the second multi-axis robotic arm 6. The side of the injection molding machine 7 also has a conveyor belt 8; the second actuation suction cup adsorbs multiple latches 1 injection molded parts and is fed onto the conveyor belt 8 by the second multi-axis robotic arm 6.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
