Description

Technical Field

[0001] This invention relates to the technical field of dental floss processing equipment, and in particular to a material picking and positioning mechanism and a dual-station positioning and picking / placing device. Background Technology

[0002] In the processing of dental floss picks, after the first injection molding, the product needs to be picked up and then sent to other processes for further processing. For example, after picking up the product, it enters the hot-stamping area for hot-stamping, and then enters the injection mold, etc.

[0003] The existing gripping method is to use a robotic arm, but dental floss products are relatively thin and the mold cavity is shallow. The position of the product is not accurate enough after being gripped or lowered, which can easily affect the subsequent processing of the product and affect the quality of the product. Summary of the Invention

[0004] The purpose of this invention is to provide a material picking and positioning mechanism and a dual-station positioning and picking device, which solves the technical problem of insufficient positioning of dental floss products when they are placed into the mold cavity in the prior art.

[0009] A pin fixing plate is disposed above the suction cup connecting plate;

[0010] The material pushing assembly has one end connected to the bottom side of the ejector pin fixing plate, and the other end passes through the suction cup connecting plate and the suction cup in sequence;

[0011] A pusher cylinder is mounted on the ejector pin fixing plate, and the piston rod end of the pusher cylinder is connected to the suction cup connecting plate.

[0019] Furthermore, a tapered hole is provided inside the guide sleeve;

[0020] The tapered pin is divided into an adjustment section and a transition section. The adjustment section is conical and fits into the tapered hole. The transition section is cylindrical. The advantage of this step is that it can create a gap after being squeezed, which facilitates adjustment.

[0025] The push spring is fitted onto the ejector pin. The advantage of this step is that the ejector pin facilitates subsequent material removal.

[0026] Furthermore, the suction cup has multiple product grooves on its bottom side, which correspond to the ends of the pusher assembly. The advantage of this step is that it facilitates the subsequent adsorption and handling of products.

[0027] This application also discloses a dual-station positioning and pick-and-place device, comprising:

[0028] At least two material handling and positioning mechanisms are arranged side by side at intervals;

[0029] The connecting frame is connected at one end to the material picking and positioning mechanism;

[0053] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0054] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0056] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0057] Example:

[0058] like Figure 1-5 As shown, this application discloses a material picking and positioning mechanism for removing semi-finished products from the injection mold, and then accurately placing them into the injection mold for secondary injection molding after hot-stamping.

[0059] Its specific structure includes:

[0060] Suction cup connecting plate 1, which is a flat plate, is used to assemble corresponding parts and facilitates its connection with other parts.

[0061] The suction cup 2 is located below the suction cup connecting plate 1. When in use, the suction cup 2 is connected to a negative pressure air source and has a corresponding air passage connected to it to adsorb the product.

[0062] Multiple fine-tuning components 3 are disposed between the suction cup connecting plate 1 and the suction cup 2. These fine-tuning components 3 are used to make fine adjustments to ensure the accuracy of the suction cup 2 in adsorbing products, and to make the product placement in the mold cavity position more precise.

[0063] The ejector pin fixing plate 4 is disposed above the suction cup connecting plate 1. The ejector pin fixing plate 4 is used to install the corresponding pushing component to ensure stability. At the same time, the subsequent pushing component can perform telescopic movement to complete the pushing process, so that the product can be removed from the suction cup.

[0064] The pusher assembly 5 is connected at one end to the bottom side of the ejector pin fixing plate 4, and the other end passes through the suction cup connecting plate 1 and the suction cup 2 in sequence. The movable end of the pusher assembly 5 needs to pass through the suction cup 2 to directly push the product and make it detach, thereby improving work efficiency.

[0065] The pusher cylinder 6 is installed on the ejector pin fixing plate 4, and the piston rod end of the pusher cylinder 6 is connected to the suction cup connecting plate 1, that is, the pusher cylinder 6 can drive the suction cup connecting plate 1 and the suction cup 2 to move up and down together.

[0066] This application also includes a guide mechanism 11, which is installed at intervals on the ejector pin fixing plate 4, and the end of the guide mechanism 11 is connected to the suction cup connecting plate 1. The guide mechanism 11 is a guide post, which facilitates the stable up and down movement of the suction cup 2 and the suction cup connecting plate 1.

[0067] In one embodiment, the fine-tuning component 3 includes:

[0068] The guide sleeve 301 is installed inside the suction cup connecting plate 1 and cooperates with the subsequent tapered pin 302 to achieve local adjustment;

[0069] A tapered pin 302, one end of which is installed inside the tapered pin 302, and the other end of which is connected to the suction cup 2, the tapered pin 302 being tapered;

[0070] A fine-tuning spring 303 is fitted onto the tapered pin 302, and the fine-tuning spring 303 is disposed between the guide sleeve 301 and the suction cup 2.

[0071] The guide sleeve 301 has a tapered hole 304 inside;

[0072] The tapered pin 302 is divided into an adjustment section 305 and a transition section 306. The adjustment section 305 is conical and mates with the tapered hole 304. The transition section 306 is cylindrical.

[0073] To further explain the fine-tuning component 3 in this application, when the suction cup 2 places the product, it will be subjected to a certain counter-force. At this time, a gap appears in the fine-tuning component 3, and the tapered pin 302 will automatically fine-tune. Specifically, after the suction cup 2 contacts the product, it generates a counter-force, causing the transition section 306 between the suction cup 2 and the tapered pin 302 to move upward. At this time, a gap appears between the adjustment section 305 and the tapered hole 304, allowing the suction cup 2 to tilt, so that the product fits into the mold cavity and ensures the accuracy of placement.

[0074] Specifically, the adjustment section 305 is a cone with a cross-sectional diameter that gradually decreases from top to bottom, which ensures that the adjustment section 305 can form a sufficient gap for the suction cup to adjust.

[0075] The feeding component 5 includes:

[0076] The pusher plunger 501 is connected at one end to the ejector pin fixing plate 4 and at the other end passes through the suction cup connecting plate 1;

[0077] The ejector pin 502 has one end located inside the pusher plunger 501 and the other end passing through the suction cup 2;

[0078] The pusher spring 503 is fitted onto the ejector pin 502. The pusher assembly 5 in this application can achieve stable separation of the product and the suction cup. That is, the pusher cylinder 6 pushes the suction cup connecting plate 1 downward. At this time, the suction cup 2 contacts the product and generates a counter-pushing force, causing the suction cup to move upward. The ejector pin 502 can then extend out of the suction cup 2, thereby causing the product to detach from the suction cup and complete the separation.

[0079] In another embodiment, the bottom side of the suction cup 2 is provided with a plurality of product grooves 7, which correspond to the end of the pusher assembly 5. The product grooves 7 are used to precisely fit the corresponding products. One of the product grooves 7 cooperates with at least one pusher assembly 5 pin 502 to achieve the product detachment from the suction cup 2.

[0080] like Figure 6-7 As shown, this application also discloses a dual-station positioning and pick-and-place device, comprising:

[0081] At least two material handling and positioning mechanisms are arranged side by side at intervals;

[0082] The connecting frame 9 is connected at one end to the material picking and positioning mechanism 8;

[0083] At least one picking and placing mechanism 10 is installed at the other end of the connecting frame 9; the connecting frame 9 can be connected to a power component, such as a robot arm, during subsequent operation, wherein the picking and positioning mechanism 8 is the aforementioned component.

[0084] The picking and placing mechanism 10 includes:

[0085] The pick-and-place plate 1001 is connected to the connecting frame 9;

[0086] At least two pick-and-place suction cups 1002 are installed at intervals below the pick-and-place plate 1001.

[0087] Among them, a plurality of fine-tuning components 3 are provided at intervals between the pick-and-place plate 1001 and the pick-and-place suction cup 1002, because the pick-and-place mechanism 10 is also used to pick up products, and the fine-tuning components 3 can further improve the accuracy of picking up products.

[0088] The following further explains: After the first injection molding, the material handling and positioning mechanism 8 enters the mold cavity. Using a positioning pin, it lowers the contour jig and suction cups to pick up the product. Then, it enters the heat setting area for the heat setting process. Afterward, it enters the injection mold. Using the positioning pin, the contour jig is lowered to place the product (dental floss products are thin, and the mold cavity is shallow, so the product's position is not precise after placement). Using the fine-tuning component 3, the product is pressed a second time to ensure it is fully positioned within the mold cavity. The mechanism then exits the mold cavity. After the second injection molding is completed, the picking and placing mechanism 10 enters the mold to grab the product and proceed to the next process step.
