Description

Technical Field

[0001] The utility model relates to the field of production and processing of injection molding products, in particular to a feeding mechanism for metal inserts used for injection molding. Background Art

[0002] Injection molded parts refer to a variety of injection-molded products produced by injection molding machines, including various packaging and parts. Some products require components, such as screws and rivets, to be embedded within the molded part. This allows these components to be directly integrated with the molded part, saving subsequent assembly time and steps while improving the quality of the assembly between the component and the molded part.

[0003] like Figure 1 The above is a probe assembly, which is loaded by a vibrating loading tray, sorted and transported through a vibrating feeding chute, and then pre-buried in the mold for injection molding. When the probe is loaded into the mold, its head needs to be inserted into the mold (the head will not be injection molded in the plastic), and the tail of the probe faces the mold opening direction. The probe assembly is relatively long, and the head size of the probe is smaller than the tail size of the probe. Therefore, the head of the probe is set upward. In this way, if a manipulator is used to grab the material, it can only grab the material from the bottom of the vibrating loading slide, and then grab and move it away from the vibrating feeding chute, and then insert a probe into the mold. In fact, multiple probes need to be pre-buried in the product at a time, and there is a distance between adjacent probes. Therefore, after the manipulator grabs a probe each time, it moves to a certain position and waits for the vibrating feeding chute to move the next probe to the corresponding position for grabbing. In this way, the efficiency is relatively low. Alternatively, the robot moves a certain distance to grasp the material. In this method, when the probes are transported on the probe feeding chute, the distance between adjacent probes varies, and the robot's grasping accuracy is insufficient, making it difficult to ensure grasping accuracy. If manual grasping is used, the efficiency is relatively low, and the labor intensity of the operator is relatively high. Summary of the Invention

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0040] Example 1: See Figure 1-9 As shown, a feeding mechanism for metal inserts for injection molding includes a vibrating feeding chute 11 installed on a machine platform 1, a gripping mechanism, and an intermediate transmission mechanism. A feeding chute 12 is provided in the middle of the vibrating feeding chute 11, and the right end of the feeding chute 12 is connected to the right end surface of the vibrating feeding chute 11;

[0041] The intermediate transmission mechanism includes a blocking mechanism 2 and a pressing mechanism 4. The blocking mechanism 2 is provided with a longitudinally movable blocking member 21. The rear end of the blocking member 21 is movably arranged above and below the vibrating feed chute 11, and the right end surface of the blocking member 21 is flush with the right end surface of the vibrating feed chute 11.

[0042] The pressing mechanism 4 is provided with a pressing plate 41, which can be longitudinally moved on the right side of the vibrating feeding chute 11 and laterally slidably arranged on the machine table 1. The pressing plate 41 is provided with at least two spaced slots 42 that match the feeding chute 12.

[0043] The grabbing mechanism 6 includes a grabbing claw 61 and a driving mechanism for driving the grabbing claw 61 to move. The driving mechanism drives the grabbing claw 61 to move below the right end of the vibrating feeding chute 11 and to the right side of the machine platform 1 .

[0044] See also Figure 2 As shown, the left end of the vibrating feeding chute 11 is connected to a vibrating loading tray 13 , and the top and bottom of the feeding chute 12 are respectively connected to the top surface and bottom surface of the vibrating feeding chute 11 .

[0045] In this embodiment, the product is a probe assembly, which is relatively long. Figure 1As shown. During loading, the product 10 is in the vibrating loading tray, and the vibrating loading tray sorts the products in sequence and feeds them into the feeding chute of the vibrating feeding chute. The depth of the feeding chute is less than the length of the product, and the diameter above the middle of the product is larger than the width of the feeding chute. Therefore, the middle of the product can be transported to the right along the feeding chute, the bottom of the product is below the bottom of the vibrating feeding chute, and the top of the product is above the top surface of the vibrating feeding chute. The product is transported to the right to the right end of the feeding chute. Under normal circumstances, it will fall out of the right end of the feeding chute. In this embodiment, by setting a pressing plate and setting at least two longitudinally spaced slots on the pressing plate, in this embodiment, the width of the slot is equal to the width of the feeding chute, and the depth is equal to the size of the product in the feeding chute, or slightly larger than the size of the product. When the product moves to the right end of the feeding chute, the pressing plate will move horizontally to the left and contact the right side of the vibrating feeding chute, and the slot at the rear end is facing the feeding chute. A product moves to the right and enters the slot, and then the pressing plate moves longitudinally backward for a distance. The slot drives the product in the slot to move backward, so that the front slot is facing the feeding chute, so that the next product can enter the next slot, until all slots have a product, and the pressing plate will press the product on the right end face of the vibrating feeding chute. The position of the slot on the pressing plate matches the embedding position on the mold to be loaded, and then the grab claw grabs the bottom of all the products in the slot from below, and the pressing plate moves horizontally to the right to disengage from the vibrating feeding chute and the product. At this time, the grab claw can remove the product and wait for the robot on the injection molding machine to grab all the products at the same time and embed them into the mold. In this embodiment, since the product is conveyed to the right in the feeding chute by vibration force, when the product enters a slot from the feeding chute, and then the pressing plate moves backward to push the product to move backward out of the feeding chute and to the right end of the vibrating feeding chute, due to the vibration feeding, there will be some gaps between adjacent products. The product may be partially in the feeding chute and partially in the slot, thereby blocking the backward movement of the pressing plate. Therefore, a stopper is also provided. After a product enters the slot, the stopper moves backward to block the product entering the slot, preventing it from moving to the left and ensuring that the product is completely in the slot, thereby ensuring that when the pressing plate moves backward, the product can be smoothly pushed by the pressing plate to move backward and to the rear end of the feeding chute. The stopper then moves forward to separate from the feeding chute, and the product on the left continues to move to the right and enter the slot of the pressing plate. Of course, in the present invention, the pressing plate can also be moved from back to front to limit the product by using multiple slots.

[0046] See also Figure 3 、 6As shown in Figure 7, the material blocking mechanism 2 includes a longitudinal cylinder 22 and a material blocking member 21. A first vertical frame 23 is provided on the front side of the vibrating feeding slide 11. The longitudinal cylinder 22 is installed on the first vertical frame 23. The left front end of the material blocking member 21 is slidingly connected to the side wall of the longitudinal cylinder 22. The output shaft of the longitudinal cylinder 22 is connected to the material blocking member 21. The longitudinal cylinder 22 drives the material blocking member 21 to move longitudinally.

[0047] The right side of the material blocking member 21 is flush with the right side of the vibrating feeding chute 11;

[0048] The material blocking member 21 includes a first plate 24 and an extension plate 25 arranged at the top and bottom of the rear end of the first plate 24. The first plate 24 is arranged on the front side of the vibrating feeding chute 11. The longitudinal cylinder 22 is connected to the first plate 24. The two extension plates 25 are respectively arranged above and below the vibrating feeding chute 11. The right side of the extension plate 25 is flush with the right side of the material blocking member 21. The rear side surface of the material blocking member 21 is a slope 26, and the slope 26 is arranged to be inclined backward from right to left.

[0049] When the output shaft of the longitudinal cylinder 22 is retracted, the rear end plane of the extension plate 25 is arranged in front of the front end plane of the feeding chute 12 at the extension plate 25;

[0050] When the output shaft of the longitudinal cylinder 22 is extended, the rear end plane of the extension plate 25 is arranged on the rear side of the rear end plane of the feeding chute 12 at the extension plate 25, and the rear end plane of the extension plate 25 is arranged close to the rear end plane of the vibrating feeding chute 11.

[0051] In this embodiment, a U-shaped structure with a rearward opening is formed between the two extension plates and the first plate, and the top plane of the upper extension plate will be below the top plane of the product, and the bottom plane of the lower extension plate will be above the bottom plane of the product. Therefore, when the blocking member moves backward, the two extension plates are respectively inserted between the upper and lower parts of the adjacent products. In this way, when the pressing plate moves backward and pushes the product backward to leave the feeding chute through the card slot, the two extension plates will limit the upper and lower parts of the product to prevent the product from tilting above or below, ensuring that the product can move backward smoothly (taking the product moving backward to leave the right end of the feeding chute as an example, the product can also move forward to leave the front end of the feeding chute). After a product leaves the feeding chute, the output shaft of the longitudinal cylinder retracts, so that the extension plate is at the front end of the product, and the product can continue to move to the right and enter the next card slot.

[0052] Furthermore, in order to ensure that the product will not be partially in the feeding chute and partially in the card slot, and to ensure that the pressing plate can smoothly push the product to move longitudinally out of the right end of the feeding chute through the card slot, an inclined surface is also provided on the rear end face of the extension plate, and a sharp angle is formed between the inclined surface and the left side face of the extension plate. The sharp angle will be inserted between adjacent products, and then when the extension plate moves backward, the inclined surface is used to push the product to move to the right until the inclined surface is completely out of contact with the left side face of the product, and after the right side face of the extension plate contacts the product, the product will be completely in the card slot, and when the pressing plate moves longitudinally, the card slot can drive the product to move longitudinally out of the feeding chute. In the present utility model, the inclined surface is provided on the rear side face of the extension plate. In this embodiment, the inclined surface is provided on the rear side face of the upper extension plate, and no inclined surface is provided on the lower extension plate. Of course, inclined surfaces can be provided on the rear sides of both extension plates.

[0053] See also Figure 3 、 5 As shown, the pressing mechanism 4 includes a transverse cylinder 43, a second longitudinal cylinder 44 and a pressing plate 41. The bottom of the transverse cylinder 43 is installed on the machine 1 on the right side of the stop member 21. The top of the transverse cylinder 43 is provided with a second vertical frame 45 for horizontal sliding. The output shaft of the transverse cylinder 43 is connected to the second vertical frame 45. The second longitudinal cylinder 44 is installed on the left side of the second vertical frame 45. The right side of the pressing plate 41 is slidably connected to the left side wall of the second longitudinal cylinder 44. The output shaft of the second longitudinal cylinder 44 is connected to the pressing plate 41. The second longitudinal cylinder 44 drives the pressing plate 41 to move longitudinally.

[0054] When the output shaft of the transverse cylinder 43 is extended, the second longitudinal cylinder 44 and the pressure plate 41 move to the left, and the left side of the pressure plate 41 is close to the right side of the vibrating feeding chute 11 or is against the right side of the vibrating feeding chute 11; when the output shaft of the transverse cylinder is retracted, there is a transverse distance between the pressure plate and the right side of the vibrating feeding chute.

[0055] In this embodiment, the transverse cylinder drives the second stand to move laterally, that is, drives the blank holder to move laterally. When the transverse cylinder output shaft is extended, the blank holder moves to the left and contacts the right end face of the vibrating feed chute. In order to prevent rigid friction between the blank holder and the vibrating feed chute when the blank holder moves longitudinally, preferably, when the transverse cylinder output shaft is extended, there is a micro-gap between the left side of the blank holder and the right end face of the vibrating feed chute, so that when the second longitudinal cylinder output shaft extends or retracts, the blank holder will not be subject to sliding resistance from the right end face of the vibrating feed chute when the blank holder moves longitudinally. Of course, the blank holder can also contact the right end face of the vibrating feed chute, and the right end face of the vibrating feed chute and the left side of the blank holder adopt relatively smooth surfaces, so that the sliding friction between the two is relatively small. In this embodiment, when the longitudinal cylinder output shaft is retracted, the rearmost slot is arranged opposite the feed chute, and when the longitudinal cylinder output shaft is extended, the frontmost slot is arranged opposite the feed chute.

[0056] See also Figure 5 As shown, two said slots 42 are provided on the left side of the pressing plate 41 at intervals in front and back, and the two ends of said slots 42 are respectively connected to the top surface and the bottom surface of the pressing plate 41;

[0057] When the output shaft of the second longitudinal cylinder is in a retracted state, the rear slot is arranged opposite to the feeding chute; when the output shaft of the second longitudinal cylinder is in an extended state, the front slot is arranged opposite to the feeding chute.

[0058] See also Figure 2 、 4 As shown in , 8 and 9, the machine 1 is provided with a mounting frame 14, and the driving mechanism is mounted on the mounting frame 14;

[0059] The driving mechanism includes a swing cylinder 62, a transverse driving mechanism 63 and a vertical driving mechanism 64. The transverse driving mechanism 63 and the vertical driving mechanism 64 are installed on the mounting frame 14. The transverse driving mechanism 63 is configured to drive the vertical driving mechanism 64 to move transversely along the mounting frame 14.

[0060] The swing cylinder 62 is connected to the vertical drive mechanism 64 via a slide 65, and the vertical drive mechanism 64 is configured to drive the slide 65 and the swing mechanism 62 to move vertically;

[0061] The material grabbing claw 61 is connected to the output shaft of the swing cylinder 62 via a connecting portion, and the swing cylinder 62 drives the connecting portion to rotate.

[0062] In this embodiment, a transverse rail is provided on the mounting frame, and the transverse drive mechanism is a combination of a transverse motor and a transverse lead screw. The transverse lead screw is arranged parallel to the transverse rail, and both ends of the transverse lead screw are rotatably connected to the mounting frame. The transverse motor drives the transverse lead screw to rotate. A slide 66 is slidably provided on the transverse rail. The vertical drive mechanism is mounted on the slide. The transverse lead screw is screwed to the slide. When the transverse lead screw rotates, it drives the slide to move laterally along the transverse rail, causing the grab claw to move laterally to the lower right side of the vibrating feed chute or to the right side of the vibrating feed chute, and the slide slides vertically on the slide. The vertical drive mechanism is a combination of a vertical motor and a vertical lead screw. The vertical rail is provided on the front end surface of the slide. The vertical lead screw is parallel to the side of the vertical rail. The vertical motor drives the lead screw to rotate. The slide slide is slidably provided on the vertical rail. The slide slide is screwed to the vertical lead screw. When the vertical lead screw rotates, it drives the slide slide along the vertical rail, thereby driving the grab claw to move vertically. Of course, the horizontal driving mechanism and the vertical driving mechanism may also adopt cylinders or other structures, which can respectively drive the grabbing claws to move horizontally and vertically.

[0063] See also Figure 9 As shown, the connecting part includes a disc 67 and a connecting plate 68. The output shaft of the swing cylinder 62 is connected to the middle part of the disc 67. The rear end of the connecting plate 68 is connected to the outer edge of the front end surface of the disc 67. The grabbing claw 61 is installed on the connecting plate 68.

[0064] When the material-grabbing claw needs to grab multiple products stuck in the slot at the same time, the connecting plate is located below the disc. After the material-grabbing claw grabs the bottom of multiple products, the pressure plate moves to the right and separates from the vibrating feeding chute. The horizontal driving mechanism first drives the material-grabbing claw with the product to move to the right, so that the product is separated from the right end face of the vibrating feeding chute and has a certain distance between it and the right end of the vibrating feeding chute. At the same time, after it moves horizontally to the right and into position, the swing cylinder can drive the disc to rotate 90 degrees, so that the vertical product is rotated to a horizontal state (which can be adjusted arbitrarily according to the angle of the mold and the product socket), and when the swing cylinder is actuated, the vertical driving mechanism also drives the material-grabbing claw and the product to move upward and into position. At this time, the product is in a horizontal state, and the subsequent robot arm of the injection molding machine can grab multiple products at the same time and then embed them into the mold of the injection molding machine. During this process, the pressing plate continues to press and position multiple products, while the gripping claw returns to its original position, waiting for the next product to be picked up. This method can automatically pick up multiple products and insert them into the mold of the injection molding machine at once, eliminating the need for manual loading and unloading. This is highly efficient and requires only the operator to regularly place the products into the vibrating loading tray, which reduces the labor intensity of the operator.
