Technical Field

[0001] This application relates to the field of injection molding production technology, and in particular to an insert alternating feeding mechanism for injection molding machines. Background Technology

[0002] In injection molding, it is often necessary to embed components of different materials inside the plastic. These components typically include metal, glass, wood, fiber, paper, rubber, or pre-molded plastic parts. These are collectively called inserts. Embedding the inserts into the injection molding machine is the key step in insert feeding. Current technology usually uses an insert feeding machine to achieve this. It is mainly responsible for accurately feeding the pre-prepared inserts into the injection molding machine to ensure the smooth progress of the production process. The insert feeding mechanism of the injection molding machine is very important for improving the degree of automation, efficiency, and precision of production.

[0003] In the existing technology, there are many different styles of inserts. How to efficiently embed complex inserts into plastic has become a major concern in the industry. Existing insert feeding mechanisms also have the problem of low feeding efficiency for complex inserts. Therefore, it is urgent to develop a stable and efficient insert feeding mechanism. Utility Model Content

[0004] The purpose of this application is to provide an insert alternating feeding mechanism for injection molding machines to solve the problem of low feeding efficiency of current injection molding inserts.

[0005] The technical solution of this utility model is that this application provides an insert alternating feeding mechanism for an injection molding machine, including an insert feeding mechanism and an insert picking mechanism. The insert picking mechanism is used to move the insert feeding mechanism, which places the inserts, to a preset station. The insert feeding mechanism includes a frame, on which a first feeding tray and a second feeding tray for storing inserts are provided; The first and second loading trays are respectively mounted on the slide table device and can reciprocate on the slide table along the first direction. During the movement of the first and second loading pallets, the projections of the first loading pallet on the frame and the projections of the second loading pallet on the frame overlap.

[0006] Preferably, the first loading pallet is at a higher horizontal height on the frame than the second loading pallet is on the frame, and the second loading pallet reciprocates between the first loading pallet and the frame in a first direction.

[0007] Preferably, a first positioning mechanism is provided on the first feeding tray, a second positioning mechanism is provided on the second feeding tray, and a third positioning mechanism is provided on the insert picking mechanism. The third positioning mechanism can be positioned with the first positioning mechanism and the second positioning mechanism respectively.

Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Thus, a feature defined with "first," "second," and "third," etc., may explicitly or implicitly include one or more of that feature.

Moreover, the terms "comprising" and "being," and any variations thereof, are intended to cover non-exclusive inclusion.

[0020] like Figure 1As shown, this embodiment provides an insert alternating feeding mechanism 1 for an injection molding machine. The insert alternating feeding mechanism 1 is set on one side of the injection molding machine 2. The inserts on the insert alternating feeding mechanism 1 are taken out by the robotic arm 3 and placed into the injection molding machine for embedding. The product after injection molding is also taken out by the robotic arm 3 and placed into the next station. In this embodiment, the insert embedding is vertical. The insert picking mechanism 4 is installed at the picking end of the robotic arm 3. The insert is embedded and picked up by the robotic arm 3 by moving the insert picking mechanism 4 up and down. In order to achieve more efficient embedding and picking, four inserts need to be embedded at one time in this embodiment. Therefore, the robotic arm 3 needs to pick up four fixed-position inserts from the insert alternating feeding mechanism 1 at one time. For complex inserts that cannot be automatically fed by the machine, this embodiment manually feeds them onto the insert alternating feeding mechanism 1, and then the robotic arm 3 picks them up and puts them into the injection molding machine 1 for embedding.

[0021] like Figure 2 As shown, the insert alternating feeding mechanism 1 includes a frame 10, on which a first feeding tray 11 and a second feeding tray 12 for storing inserts are provided. In this embodiment, since the insert structure to be embedded is relatively complex, the traditional automatic feeding method is not applicable. Therefore, this embodiment adopts a manual feeding method. To improve the feeding efficiency of manual feeding, repeated and uninterrupted feeding is required. In this example, the use of the first feeding tray 11 and the second feeding tray 12 allows the operator to perform the feeding work on the second feeding tray 12 after the first feeding tray 11 is finished.

[0022] To enable alternating feeding of the first feeding tray 11 and the second feeding tray 12, this embodiment mounts the first feeding tray 11 and the second feeding tray 12 on the slide device 13 located on the frame 10, respectively. The first feeding tray 11 and the second feeding tray 12 can reciprocate horizontally, while vertically they are arranged vertically, with the first feeding tray 11 positioned above the second feeding tray 12. This ensures that the horizontal movements of the first feeding tray 11 and the second feeding tray 12 do not interfere with each other. Furthermore, to facilitate material handling by the robotic arm 3, positioning mechanisms 14 are provided on both the first feeding tray 11 and the second feeding tray 12, allowing the robotic arm 3 to confirm the positions of the first feeding tray 11 and the second feeding tray 12 before moving to handle materials.

[0023] like Figure 3As shown, the slide device 13 includes a first slide 131 and a second slide 132. The first slide 131 is disposed outside the second slide 132. In this embodiment, the first slide 131 adopts a combination of linear guide rail and slider, and the second slide 132 adopts a combination of linear guide rail and slider. The first loading tray 11 is mounted on the slider of the first slide 131, and the second loading tray is mounted on the slider of the second slide 132. Thus, the first loading tray 11 and the second loading tray 12 can reciprocate in the horizontal direction. Since the first slide 131 is disposed outside the second slide 132, the first loading tray 11 mounted on the first slide 131 and the second loading tray 12 mounted on the second slide 132 will not interfere with each other during linear movement. During the movement of the first loading pallet 11 and the second loading pallet 12, the projection of the first loading pallet 11 on the frame 10 and the projection of the second loading pallet on the frame have an overlapping portion. Thus, after the operator completes loading one of the loading pallets, the operator moves the loading pallet toward the loading station. At the same time, the other loading pallet can be moved away from the loading station and move to the vicinity of the operator to complete the loading.

[0024] like Figure 3 As shown, the positioning mechanism 14 includes a first positioning mechanism 141 disposed on the first loading tray 11 and a second positioning mechanism 142 disposed on the second loading tray 12. In this example, both the first positioning mechanism 141 and the second positioning mechanism 142 are positioning holes, which can cooperate with the guide posts on the robot arm 3 to achieve positioning. To avoid interference between the positioning mechanism and the picking mechanism during the picking process of the robot arm 3, in this embodiment, the first positioning mechanism 141 is disposed at the edge of the first loading tray 11, and the second positioning mechanism 142 is disposed at the edge of the second loading tray. Moreover, the positioning center points of the first positioning mechanism 141 and the second positioning mechanism 142 coincide, that is, the positioning hole of the first positioning mechanism 141 and the positioning hole of the second positioning mechanism 142 are concentric at the picking position of the robot arm 3, thereby ensuring that the robot arm 3 can still accurately position and pick up materials even after the first loading tray 11 and the second loading tray 12 are alternated during the picking process.

[0025] like Figure 4As shown, the second loading tray 12 includes a fixed plate 121 and a mounting plate 122. One end of the fixed plate 122 is mounted on the slide rail of the second slide table 132, and the other end of the fixed plate 122 is mounted on the mounting plate 122. The mounting plate 122 has an insert loading part 123. The operator manually places the inserts to be loaded one by one into the insert loading part 123. In this embodiment, in order to match the requirements of the injection molding process, four sets of insert loading parts 123 are provided, which are respectively installed at the four corners of the mounting plate 122. The size of the fixed plate 122 is larger than the size of the mounting plate 122. A positioning mechanism 14 is provided on the fixed plate 122. In this embodiment, two sets of positioning mechanisms 14 are provided, which are respectively installed on both sides of the fixed plate 122. At the same time, the positioning mechanism 14 is configured as a positioning hole.

[0026] like Figure 5 As shown, a third positioning mechanism 41 is installed on the insert picking mechanism 4. The third positioning mechanism 41 is installed on the edge of the insert picking mechanism 4 to avoid interference when the insert is put into the injection molding machine. At the same time, the third positioning mechanism 41 is set as a positioning guide post to cooperate with the positioning holes of the first positioning mechanism 141 and the second positioning mechanism 142 to achieve positioning. The insert picking mechanism 4 is also provided with a picking claw 42 to pick up the insert after positioning between the insert picking mechanism 4 and the loading tray. At the same time, the number of claws is also set to match the number of sets of inserts, which is 4. The 4 claws move to the loading tray at the same time to pick up 4 sets of inserts.

[0027] Combination Figure 2 , 3 A loading station is provided on one side of the frame 10. A manual button 15 is provided on the loading station. After the operator completes the manual placement of the insert, the first loading tray 11 and the second loading tray 12 move alternately by pressing the manual button 15, so as to realize the interchange of the loading station and the unloading station.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
