Description

Technical Field

[0001] This utility model relates to the technical field of loading and unloading equipment for injection molding machines, and in particular to the end effector of a loading and unloading robot for a horizontal injection molding machine. Background Technology

[0002] Horizontal injection molding machines are common injection molding equipment, often used to produce workpieces made from plastic. They include a feeding system for providing raw materials and upper and lower molds for injection molding.

[0003] Currently, manual material cutting is commonly used in the injection molding of some workpieces. Similarly, when injection molding workpieces with inserts, the inserts also need to be manually placed into the mold before the injection molding process is completed. Currently, most inserts on the market are nuts, meaning that the nuts need to be manually placed on the mold before the injection molding machine performs the injection molding.

[0004] However, after repeated and lengthy processing, injection molds reach high temperatures, and the mold area of ​​the injection molding machine is the working area. Therefore, manually performing complex processes is highly dangerous and inefficient. Although some robotic arms have emerged to replace manual labor, they are primarily used for unloading injection molded parts.

[0005] Therefore, a new technical solution is urgently needed to solve at least one of the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide an end gripper for a horizontal injection molding machine's loading and unloading robot, which is installed on the robot to replace manual labor in completing the work of installing inserts and unloading materials, thereby solving the above-mentioned technical problems.

[0007] The end effector of the loading / unloading robot for a horizontal injection molding machine, mounted on the robot arm, includes:

[0008] The mounting plate has a first end and a second end opposite to each other, and a connecting seat is fixedly provided in the middle of the mounting plate for detachable connection with the end of the robot arm.

[0014] Furthermore, an observation hole is provided on the base body that intersects with the receiving hole, and the observation hole penetrates the base body, and the observation hole has a length extending along the axis of the receiving hole.

[0015] Furthermore, a detection element is installed on the base, and two detection heads are provided on the detection element. The detection heads are located at the two ends of the observation hole in the vertical direction and are directed toward the receiving hole for detection.

[0016] Furthermore, the detection head is a photoelectric sensor.

[0017] Furthermore, a stripping assembly is also provided on the second end of the mounting plate. The stripping assembly is correspondingly provided with the loading assembly and is used to remove the workpiece located within the receiving hole. The stripping assembly includes:

[0018] A stripping rod is provided corresponding to the feeding fixture and is slidably connected to the mounting plate. One end of the stripping rod extends into the receiving hole along the receiving hole and faces the mounting plate.

[0019] A driving component is disposed on the mounting plate and is connected to the stripping rod for transmission, driving the stripping rod to reciprocate within the receiving hole.

[0020] Furthermore, the driving component includes:

[0021] A drive cylinder, which is fixedly mounted on the mounting plate;

[0030] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in the embodiments of this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0033] This utility model provides a horizontal injection molding machine loading and unloading robot end gripper, which is installed on the robot arm to grip the insert and install it into the injection molding machine mold. At the same time, it can remove the already injected workpiece from the mold. The loading and unloading actions can be completed by a single gripper, thereby replacing manual labor and improving production efficiency.

[0034] Specifically, such as Figure 1-4 As shown, the end effector of the horizontal injection molding machine loading / unloading robot provided in this embodiment includes a mounting plate 100, a clamping assembly 110, and a loading assembly 120. The mounting plate 100 has a first end 101 and a second end 102 opposite to each other, and a connecting seat 103 is fixedly provided in the middle of the mounting plate 100 for detachable connection with the end effector of the robot. The clamping assembly 110 is mounted on the first end 101 and includes at least two pneumatic clamps 111 arranged side by side. The loading assembly 120 is disposed on the second end 102 and includes a plurality of loading fixtures 121 arranged side by side. The loading fixtures 121 have receiving holes 122 formed at their ends to receive the workpieces.

[0035] The mounting base is connected to the end of the robot via a flange, enabling the robot to drive its movements. During the gripping of the insert, the robot moves the loading fixture 121 toward the insert and presses the insert to lock it into the receiving hole 122, completing the gripping action. Subsequently, the robot drives the gripper to move toward the injection molding machine, so that the pneumatic clamp 111 removes the injection-molded workpiece from the mold and places the gripped insert inside the mold. It is worth noting that in this embodiment, the insert is a nut.

[0036] In this embodiment, the loading fixture 121 comprises a base 123 and a rod. The upper end of the base 123 is fixedly mounted on the mounting plate 100. The rod is formed on the base 123, and a receiving hole 122 is formed at the end of the rod, penetrating both the rod and the base 123. By providing the rod 124, the size of the end of the loading fixture 121 is reduced, thereby adapting to operations in the small space of the injection mold cavity. Simultaneously, by setting the receiving hole 122 as a through-hole structure, multiple stacked inserts can be gripped at once, thus improving the gripping efficiency of the loading fixture 121. Furthermore, it also prevents the air pressure inside the receiving hole 122 from increasing during insert gripping, which could affect the loading of the inserts.

[0037] In this embodiment, in order to observe the loading status of the insert within the receiving hole 122, an observation hole 125 is provided on the base 123, which intersects with the receiving hole 122 and penetrates the base 123. The observation hole 125 has a length extending along the axial direction of the receiving hole 122.

[0038] To improve observation efficiency, a detection element 126 is installed on the base 123, and two detection heads 127 are provided on the detection element 126. The detection heads 127 are located at the two ends of the observation hole 125 in the vertical direction and are pointing towards the receiving hole 122 for detection. The detection heads 127 are photoelectric sensors.

[0039] During the observation of the loading status of the insert, the lower detection head 127 being triggered indicates that the insert has been loaded to the minimum loading requirement, while the upper detection head 127 being triggered indicates that the insert has reached the maximum loading value. By setting two detection heads 127, the reliability of the insert loading can be improved, and the insert may be overloaded and fall off during transportation.

[0040] In this embodiment, a stripping assembly 130 is also provided on the second end 102 of the mounting plate 100. The stripping assembly 130 is correspondingly provided with the loading assembly 120 and is used to remove the workpiece located in the receiving hole 122. The stripping assembly 130 includes a stripping rod 131 and a driving member 132. Specifically, the stripping rod 131 is correspondingly provided with the loading fixture 121 and is slidably connected to the mounting plate 100. One end of the stripping rod extends into the receiving hole 122 along the receiving hole 122 and towards the mounting plate 100. The driving member 132 is provided on the mounting plate 100 and is connected to the stripping rod 131 in a transmission manner, driving the stripping rod 131 to reciprocate within the receiving hole 122. In this embodiment, the driving component 132 includes a driving cylinder 133 and a plate 134. The driving cylinder 133 is fixedly mounted on the mounting plate 100. The plate 134 is tractively connected to the driving cylinder 133 and is driven by the driving cylinder 133 to reciprocate along the axial direction of the receiving hole 122. One end of the ejector rod 131 away from the loading fixture 121 is fixedly mounted on the plate 134. During the process of removing the insert from the receiving hole 122, the driving cylinder 133 drives the mounting plate 100 to move towards the loading fixture 121, thereby causing the ejector rod 131 to move within the receiving hole 122, pushing out the insert located within the receiving hole 122, thus completing the loading action.

[0041] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
