Description

Technical Field

[0001] The invention relates to the technical field of ceiling nail production equipment, and more particularly to an anti-dislocation and offset feeding device for batch typesetting and injection molding of ceiling nails and a feeding method thereof. Background Art

[0002] Ceiling nails consist of a nail and a plastic head that is subsequently injection-molded. The nail is fed into an injection molding machine, where the plastic material is combined with the nail's tail to form a single-piece nail. This tail injection molding process is designed to improve the safety and ease of use of ceiling nails.

[0003] Patent application number 202121842709.8 records a device for the production of ceiling nails, including nail dividing equipment, an injection molding machine and a robotic arm structure. The nail dividing equipment mainly includes a nail adsorption plate with an electromagnet adsorption head, as shown in Figure 14. The electromagnet adsorption head is arranged in an array on the nail adsorption plate. The unprocessed nails are first arranged into an array on the nail adsorption plate, and then the nails are transferred to the injection molding machine mold through the robotic arm structure for injection molding. The nail adsorption plate plays the function of batch-arranging the unprocessed nails and transferring the materials for injection molding.

[0004] However, in actual processing, in the process of transferring nails to the injection molding machine mold, due to irresistible factors such as mechanical vibration, some nails often shift their position on the electromagnet adsorption head, causing them to be misaligned with the injection molding machine mold. After being stuck, they collide and fall, making it impossible to feed the nails. In other words, the original intention was to process in batches and improve production efficiency, but the reality is that the feeding is not stable enough, its structure needs to be optimized, and its efficiency needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-dislocation and offset feeding device for batch layout injection molding of ceiling nails and a feeding method thereof to address the problem that nail position deviation is prone to occur during the existing nail layout and batch feeding process, resulting in insufficient feeding stability. The purpose is to effectively position the nails to prevent them from being dislocated and offset during the transportation process, thereby achieving stable and precise batch transportation of nails and ultimately improving overall processing efficiency.

[0006] In order to achieve the above purpose, the present invention is realized through the following technical solutions: a dislocation-proof feeding device for batch typesetting and injection molding of ceiling nails, characterized in that it includes a base plate, the base plate is connected to a panel separated and parallel to it to form a spacing space through a plurality of connecting columns, the panel is provided with a plurality of nail holes arranged in a matrix manner, each of the nail holes is respectively provided with a ejector pin extending into and out of the hole, all the ejectors are jointly provided on a needle plate, the needle plate and all the ejectors are located in the spacing space between the base plate and the panel, a lower push-pull cylinder is provided at the center of the exposed end surface of the base plate, the cylinder shaft of the lower push-pull cylinder passes through the base plate and is connected to the needle plate, and the panel is provided with a plurality of pairs of nail holes. The clamps are all long strips, and each pair of the clamps is divided into a left splint and a right splint in half along the center line of their length. A row of nail holes arranged at equal intervals along the length of their splicing seam are spliced ​​between each pair of the left and right splints. Each row of the nail holes corresponds to a row of the pair of nail holes, so that each of the nail holes corresponds to one pair of nail holes. All left splints are connected to a pair of left linkage rods, and the two left linkage rods are connected to a left push-pull rod, and the rear center of the left push-pull rod is connected to the cylinder shaft of a left push-pull cylinder. The right splints are connected to a pair of right linkage rods, and the two right linkage rods are connected to a right push-pull rod, and the rear center of the right push-pull rod is connected to the cylinder shaft of a right push-pull cylinder.

[0007] The present invention addresses the problem that nail position deviation is prone to occur during the batch feeding process of nail arrangement in the existing ceiling nail injection molding process, resulting in insufficient feeding stability. The present invention aims to effectively position the nails through anti-dislocation and offset feeding mechanisms such as clamps and ejectors to prevent them from being dislocated and offset during the conveying process, thereby achieving stable and precise batch feeding of nails and ultimately improving overall processing efficiency.

[0008] Preferably, a magnetic bead is provided on the free end of each ejector pin.

[0009] The magnetic beads have an adsorption and holding effect on the nails, which can better stabilize the nails and improve the effect during typesetting.

[0010] Preferably, all left splints are respectively provided with four left sliding rod holes corresponding to each other, allowing the two left linkage rods and the two right linkage rods to pass through and maintain their respective sliding clearances; the two left linkage rods are respectively provided with a number of left retaining rings, the same number as the number of left splints and arranged at equal intervals; each of the left retaining rings is respectively connected to one of the left splints nearby through a left spring; all right splints are respectively provided with four right sliding rod holes corresponding to each other, allowing the two left linkage rods and the two right linkage rods to pass through and maintain their respective sliding clearances; the two right linkage rods are respectively provided with a number of right retaining rings, the same number as the number of right splints and arranged at equal intervals; each of the right retaining rings is respectively connected to one of the right splints nearby through a right spring.

[0011] The linkage rod passes through the splint and is housed within the anti-misalignment feed mechanism. It doesn't protrude from the surface, nor does it interfere with subsequent nail transfer. More importantly, a spring can be added to ensure smooth, non-jerky movements. A retaining ring, similar to a circlip, secures one end of the spring. The other end of the spring fits into the corresponding hole on the slide bar, securing it to the splint. The spring connects the linkage rod to the splint.

[0012] Preferably, a positioning pin is provided on both sides of each row of the pairing nail holes, and a positioning hole is provided on both sides of each row of the holding nail holes, and the positioning pins and the positioning holes correspond to each other one by one.

[0013] The positioning pins and positioning holes play a guiding and positioning role. When the clamp is closed, the positioning of the nail holes and the nail holes can be more accurate, thereby making the position of the nails more accurate and ensuring that the nails always maintain the preset layout position.

[0014] Preferably, the above-mentioned clamp, left splint, right splint, left linkage rod, left push-pull rod, left push-pull cylinder, right linkage rod, right push-pull rod and right push-pull cylinder are regarded as a set of anti-misalignment and offset mechanisms as a whole, and at least two sets of anti-misalignment and offset mechanisms arranged side by side are provided on the panel.

[0015] The anti-misalignment mechanism can be split into two or more components, depending on the number of nail holes on the panel and the panel size. This is because the increased number of fixtures, springs, and other components creates greater resistance and operational strain, necessitating structural separation and decomposition. However, it is crucial to ensure that these push-pull cylinders and fixtures operate synchronously.

[0016] Preferably, there are four connecting columns between the bottom plate and the panel, which are respectively located at the four circumferential corners of the bottom plate and the panel.

[0017] Preferably, four alignment pins arranged side by side are provided at the center of the panel, and each of the alignment pins protrudes outside the plane where the clamp is located.

[0018] The alignment pin is protruding from the entire anti-misalignment feeding device. Its main function is to cooperate with the alignment hole on the mold to allow the nail to reach the mold smoothly during the feeding process.

[0019] A feeding method of a dislocation-proof feeding device for batch typesetting and injection molding of ceiling nails, characterized by comprising the following steps: Step 1: In the initial state, the lower push-pull cylinder, the left push-pull cylinder, and the right push-pull cylinder are all in the reset state with the cylinder shaft retracted, wherein the needle plate rests on the bottom plate, and the ejector pin with the magnetic bead retracts in the gap between the bottom plate and the panel, and does not pass into the corresponding nail hole; the left push-pull rod is on the far left, and the right push-pull rod is on the far right. At this time, the left splint and the right splint are separated, and the nail holes are open; Step 2: Start the work. The push-pull cylinder pushes the needle plate forward so that the magnetic bead at the front end of the ejector pin enters the corresponding nail hole. It stops if it does not penetrate. Then manually arrange the nails. As long as the nails are placed near the corresponding nail holes, the magnetic beads will attract the nails into place. Even if there are a few nails that are accidentally out of position, don't worry about it. Step 3: The left push-pull cylinder and the right push-pull cylinder are started synchronously, pushing the left push-pull rod and the right push-pull rod toward each other to bring them together. Then, the left linkage rod slowly overcomes the spring force of the spring to push the left splint, and the right linkage rod slowly overcomes the spring force of the spring to push the right splint, closing the left splint and the right splint. They are put into place in order through the positioning pins and positioning holes. During this process, the nail holes and the alignment holes are aligned one by one, and the nail holes also slowly adjust the nails that have deviated to ensure that the nails always maintain the preset layout position; Step 4: After the above-mentioned nail layout is completed, the material is fed and transferred to the mold of the corresponding injection molding machine. The anti-dislocation feeding device of the present invention is transported to the mold by an external manipulator, and the alignment pins and the alignment holes on the mold are used to align and match, and then slowly approach so that the front end of the nail enters the mold first; Step 5: The left push-pull cylinder and the right push-pull cylinder are reset synchronously, and the left push-pull rod and the right push-pull rod are pulled away from each other in opposite directions. Then, the left linkage rod pulls the left splint with the help of the reset force of the spring, and the right linkage rod pulls the right splint with the help of the reset force of the spring, thereby separating the left splint and the right splint. At the same time, the lower push-pull cylinder further pushes the ejector pin forward. When the tail cap of the nail can pass through the nail hole, the ejector pin with the magnetic bead is also exposed from the nail hole, thereby pushing the nail to the mold. Step 6. When the nail has completely reached the mold, the anti-dislocation offset feeding device of the present invention is withdrawn, and the left push-pull cylinder and the right push-pull cylinder are started synchronously again, and the left push-pull rod and the right push-pull rod are pushed toward each other synchronously to make them close together, and then the left linkage rod slowly overcomes the spring force of the spring to push the left splint, and the right linkage rod slowly overcomes the spring force of the spring to push the right splint, and the left splint and the right splint are closed, and the nail holes are also pieced together one by one. At this time, the nail hole is held on the ejector pin, and the nail is blocked outside the nail hole with the help of its tail cap; then, the lower push-pull cylinder is started to slowly reset, so that the ejector pin retreats and resets, and the nail is blocked with the help of the clamp. The magnetic bead slowly moves away from the nail and loses its adsorption force, and the manipulator can smoothly withdraw the anti-dislocation offset feeding device of the present invention to prepare for the next row of nails; repeat the above steps.

[0020] The feeding method of the present invention has several highlights: (1) The magnetic beads enter the nail holes, and when the nails are manually arranged, they can be arranged for the first time and absorb the nails so that the nails correspond one to one to the nail holes, forming a matrix arrangement.

[0021] (2) The magnetic beads can absorb the nails close to them, but they cannot ensure that they are absorbed in the center of the nail hole. Therefore, the nail hole formed after the left and right splints are closed has different functions in the whole process. For example, it first corrects the deviation during typesetting, then holds the material during feeding, and finally guides the material during transfer.

[0022] (3) After transferring the nail to the mold, if the anti-dislocation offset feeding device is directly withdrawn, the magnetic beads will pull the nail out and bring it back. Therefore, the ejector pin must push the magnetic beads to at least the edge of the nail hole, so that the nail is blocked outside the nail hole with the help of its own tail cap (the diameter of the nail hole after splicing is smaller than the nail tail cap, and the diameter of the nail hole after splicing is consistent with the diameter of the nail shaft, ejector pin and magnetic beads). After that, the ejector pin returns to its original position with the magnetic beads, and the magnetic beads slowly move away from the nail and lose their adsorption force, so that the anti-dislocation offset feeding device can be smoothly withdrawn without affecting the state of the nail on the mold.

[0023] Beneficial effects: (1) The effective positioning design of the nails by the anti-displacement feeding mechanism of the present invention can significantly reduce the dislocation and displacement of nails during the feeding process, ensuring that the nails always maintain the preset layout position.

[0024] (2) The optimization of the anti-dislocation feeding mechanism of the present invention makes the batch feeding process of nails more stable and avoids feeding interruption or failure caused by position deviation.

[0025] (3) The stable and precise conveying effect of the present invention directly improves the continuity and accuracy of the subsequent ceiling nail injection molding process, thereby effectively improving the overall processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
