[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] See appendix Figure 1-5 As shown, a preheating device for injection molding of injection molded parts according to Embodiment 1 includes an outer frame; an operating table 1 disposed inside the outer frame; and a clip mechanism placed on the operating table 1 for loading injection molded parts. The clip mechanism includes: a clip compartment 2; a plurality of loading plates 21 spaced from top to bottom inside the clip compartment 2, the loading plates 21 being laterally slidably connected to the clip compartment 2; and a filling groove 22 opened on the loading plates 21.

[0025] The injection molding material can be placed on the loading plate 21 through the filling groove 22, and then the loading plate 21 is installed in the magazine 2 by sliding, thereby realizing batch injection molding material feeding. The spaced distribution ensures that the loading plate 21 will not affect other loading plates 21 when it is pulled out.

[0026] An adjustment mechanism is provided on the operating table 1 for adjusting the height of the magazine mechanism; the height of the magazine compartment 2 can be adjusted by the adjustment mechanism, so that when the uppermost loading plate 21 is pulled out, the height of the magazine compartment 2 is raised, making it easier to pull out the next loading plate 21.

[0027] A traction mechanism located at the discharge point of the magazine mechanism, which is used to remove the loading plate 21 from the magazine compartment 2; a four-axis robot assembly provided on the operating table 1, which is capable of removing the injection molding material from the feeding trough 22; and a preheating mechanism for preheating the injection molded parts.

[0028] The traction mechanism can pull the loading plate 21 out of the magazine 2, and then the four-axis robot can grab the injection molding material on the loading plate 21. After grabbing, it is placed in the preheating mechanism, thereby realizing batch feeding and improving work efficiency. The four-axis robot can avoid the injection molding material from being burned when placed in the preheating mechanism, and the robot can be positioned more accurately, eliminating problems such as misplacement and tilting.

[0029] Furthermore, the adjustment mechanism includes a support plate 3 capable of supporting the magazine mechanism and performing vertical reciprocating motion; a mounting plate 31 fixed on the operating table 1; and a first linear module 32 vertically disposed at the bottom of the mounting plate 31, the moving end of which is fixedly connected to the support plate 3, thereby realizing the reciprocating motion of the support plate 3.

[0030] The operation of the first linear module 32 enables the support plate 3 to reciprocate vertically. When a fully loaded magazine 2 is placed on the support plate 3, the height of the support plate 3 can be lowered by the first linear module 32 to facilitate the traction mechanism to pull the uppermost loading plate 21. Then, the height of the support plate 3 is raised in sequence to pull out the loading plates 21 in sequence.

[0031] Furthermore, a limiting sleeve 33 is fixedly provided under the mounting plate 31. The limiting sleeve 33 has a limiting rod 34 that penetrates the mounting plate 31 inside. The limiting rod 34 is slidably connected to the limiting sleeve 33, and the top end of the limiting rod 34 is fixedly connected to the support plate 3.

[0032] The limiting sleeve 33 and the limiting rod 34 can improve stability during the lifting and lowering of the support plate 3.

[0033] Furthermore, the traction mechanism includes: a bracket 4 fixed to the mounting plate 31 and located at the discharge port of the magazine mechanism; a track 41 provided on the bracket 4 for sliding the loading plate 21; and a traction component provided inside the track 41 that can reciprocate along its length, the traction component being able to drag the loading plate 21 onto the track.

[0034] The traction component can reciprocate inside the track. Therefore, when the traction component pulls the loading plate 21, it can pull it onto the track through its movement, thereby exposing the injection molding material on the loading plate 21, making it easier for the four-axis robot arm component to grasp it.

[0035] Furthermore, the traction assembly includes: a movable block 42 capable of reciprocating within the track 41; a drive cylinder 46 disposed on the movable block 42; a traction hook 43 reciprocating via the drive cylinder 46; a hanging slot 44 on the loading plate 21 that can be hooked by the traction hook 43; a timing belt assembly 45 disposed along the length of the track, which can drive the movable block 42 to move during operation; and a drag chain 47 disposed on the movable block.

[0036] The operation of the timing belt assembly 45 can cause the movable block 42 to move, which in turn drives the drive cylinder 46 and the traction hook 43 to move. When the traction hook 43 hooks into the hanging groove 44, the drive cylinder 46 can make the traction hook 43 move laterally, so that the traction hook 43 and the hanging groove 44 are tightly engaged. Then, through the movement of the movable block 42, the loading plate 21 can be pulled out. The cable chain 47 can increase the stability of the movable block 42.

[0037] Furthermore, the four-axis robot assembly includes: a robot body 5 mounted on the operating table 1; and a clamp 51 disposed on the robot body 5 for holding injection molded parts.

[0038] The robotic arm body 5 can use the gripper 51 to grab the injection molding material on the loading plate 21 and place it on the preheating mechanism, replacing manual labor and avoiding burns.

[0039] Furthermore, the preheating mechanism includes: a support frame 61 mounted on the operating table 1; a preheating module 6 capable of reciprocating along the length of the support frame 61; a slide rail 62 mounted on the support frame 61, the slide rail 62 being arranged along the length of the support frame 61; a sliding plate 63 fixedly mounted on the bottom of the preheating module 6 and slidably connected to the slide rail 62; and a second linear module 64 mounted on one side of the slide rail 62, the moving end of the second linear module 64 being provided with a connector 65 fixedly connected to the sliding plate 63.

[0040] The four-axis robotic arm assembly can grab the injection molding material from the loading plate 21 at the track and place it on the preheating module 6 to preheat the injection molding material. After preheating, the sliding plate 63 can be moved on the slide rail 62 by the second linear module 64, thereby moving the preheating module 6 to the other end of the slide rail 62, so that the preheating material can be grabbed by the external robotic arm after preheating.

[0041] Furthermore, the preheating module 6 is provided with a preheating groove for filling the injection molded part, and the interior of the preheating module 6 is provided with several heating elements, and the bottom of the sliding plate 63 is provided with an ejector pin assembly that can eject the injection molded part.

[0042] The injection molded part can be placed in the preheating tank by the four-axis robot assembly. The preheating module 6 can be heated by the heating element, thereby preheating the injection molded part located in the preheating tank. The ejector assembly can lift the injection molded part after preheating, making it convenient for the external robot to grasp it.

[0043] Furthermore, a mounting bracket 7 is provided on the operating table 1 and above the preheating mechanism, and a temperature sensor 71 is provided on the mounting bracket 7.

[0044] Temperature sensor 71 can detect the temperature of the injection molded part. When the temperature reaches the pre-compression requirement, preheating can be stopped, and then the preheating module 6 can be moved to make the injection molded part easier to be grasped by an external robotic arm.

[0045] Furthermore, the operating table 1 is equipped with a camera 8 for incoming material positioning and detection. After the robotic arm body 5 grabs the injection molding material, it can use the camera 8 to take pictures and position it, thereby improving the accuracy of placing the injection molding components in the preheating tank.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
