Description

Technical Field

[0001] This utility model relates to the technical field of ceiling nail production equipment, and more specifically to a feeding device for preventing misalignment and offset in batch layout and injection molding of ceiling nails. Background Technology

[0002] Ceiling nails, consisting of the nail portion and a subsequently injection-molded plastic head portion, are manufactured by feeding the nail into an injection molding machine, where plastic material is then bonded to the tail of the nail to form a single, integrated nail. This tail-injection molding process for ceiling nails aims to improve their safety and ease of use.

[0003] Patent application number 202121842709.8 describes a device for producing ceiling nails, including a nail sorting device, an injection molding machine, and a robotic arm structure. The nail sorting device mainly includes a nail adsorption plate with electromagnet adsorption heads, as shown in Figure 14. The electromagnet adsorption heads are arranged in an array on the nail adsorption plate. The unprocessed nails are first arranged in an array on the nail adsorption plate, and then the robotic arm structure transfers these nails to the injection molding machine mold for injection molding. The nail adsorption plate plays the role of batch sorting and feeding the unprocessed nails to the injection molding machine.

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

[0005] The purpose of this invention is to address the problem of nail position deviation and insufficient feeding stability during the batch feeding process of existing nail layout. It provides a feeding device for preventing misalignment and deviation in the batch layout and injection molding of ceiling nails. The device aims to effectively position the nails to prevent misalignment and deviation during the feeding process, thereby stabilizing and improving the accuracy of batch nail feeding and ultimately enhancing the overall processing efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding device for batch layout and injection molding of ceiling nails to prevent misalignment and offset, characterized in that it includes a base plate, on which a panel is connected by several connecting columns to form a space between the base plate and the panel. The panel has several nail-matching holes arranged in a matrix, and each nail-matching hole has a pin extending into or out of it. All pins are mounted on a pin plate, and the pin plate and all pins are located within the space between the base plate and the panel. A push-pull cylinder is located at the center of the exposed end face of the base plate, and the cylinder shaft of the push-pull cylinder passes through the base plate and connects to the pin plate. Several... For each pair of long, narrow clamps, each pair is divided in half along its centerline into a left clamp and a right clamp. A row of equally spaced pin holes is joined between each pair of left and right clamps along the length of their joint. Each row of pin holes corresponds to a row of pin holes, thus ensuring that each pin hole corresponds to one pin hole. All left clamps are connected to a pair of left linkage rods, which are then connected to a left push-pull rod. The rear center of the left push-pull rod is connected to the cylinder shaft of a left push-pull cylinder. Similarly, the right clamps are connected to a pair of right linkage rods, which are then connected to a right push-pull rod. The rear center of the right push-pull rod is connected to the cylinder shaft of a right push-pull cylinder.

[0007] This invention addresses the problem of nail position misalignment and insufficient feeding stability during the batch feeding process of ceiling nail injection molding. It aims to effectively position the nails using anti-misalignment feeding mechanisms such as clamps and ejector pins to prevent misalignment during transportation, thereby achieving stable and accurate batch feeding of nails and ultimately improving overall processing efficiency.

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

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

[0010] Preferably, each of the left clamping plates is provided with four left sliding rod holes, each corresponding to one of the two left linkage rods and the two right linkage rods, allowing them to pass through and maintain their respective sliding gaps. Each of the two left linkage rods is fitted with a number of left retaining rings, the same number as the number of left clamping plates, arranged at equal intervals. Each left retaining ring is connected to one of the left clamping plates nearby via a left spring. Each of the right clamping plates is provided with four right sliding rod holes, each corresponding to one of the two left linkage rods and the two right linkage rods, allowing them to pass through and maintain their respective sliding gaps. Each of the two right linkage rods is fitted with a number of right retaining rings, the same number as the number of right clamping plates, arranged at equal intervals. Each right retaining ring is connected to one of the right clamping plates nearby via a right spring.

[0011] The linkage rod passes through the clamping plate and is housed within the entire anti-misalignment feeding mechanism. It does not protrude from the surface and does not interfere with subsequent nail transfer. More importantly, a spring can be added to ensure smooth and seamless mechanical pushing operation, preventing abrupt movements. The retaining ring, or spring clip, is used to secure one end of the spring. The other end of the spring can be inserted into the corresponding slide rod hole to fix it to the clamping plate, thus connecting the linkage rod and the clamping plate.

[0012] Preferably, a positioning pin is provided on both sides of each row of pin holes, and a positioning hole is provided on both sides of each row of pin holes, with the positioning pins and positioning holes corresponding to each other.

[0013] The positioning pins and positioning holes serve as guides and positions. When the clamps are closed, they make the alignment of the pin-holding holes and pin-fitting holes more precise, thus making the position of the pins more accurate and ensuring that the pins always maintain the preset layout position.

[0014] Preferably, the above-mentioned clamp, left clamp, right clamp, 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 whole set of anti-misalignment and offset mechanism, and at least two sets of anti-misalignment and offset mechanism are provided on the panel.

[0015] The anti-misalignment mechanism can be divided into two or more parts, mainly depending on the number of pin holes on the panel and the panel size. This is because more fixtures, springs, and other structures increase resistance and strain the operation, necessitating structural differentiation and decomposition. However, it is essential to ensure that these push-pull cylinders work synchronously, guaranteeing the synchronized operation of the fixtures.

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

[0017] Preferably, the panel has four alignment pins arranged side by side at its center, with each alignment pin protruding outside the plane of the fixture.

[0018] The alignment pin protrudes from the entire anti-misalignment feeding device. Its main purpose is to cooperate with the alignment hole on the mold so that the pin can smoothly reach the mold during the feeding process.

[0019] Beneficial effects: (1) The anti-misalignment feeding mechanism of this utility model has an effective positioning design for nails, which can significantly reduce the misalignment of nails during the feeding process and ensure that the nails always maintain the preset layout position.

[0020] (2) The optimized anti-misalignment feeding mechanism of this utility model makes the batch feeding process of nails more stable and avoids feeding interruption or failure due to position deviation.

[0021] (3) The stable and accurate conveying effect of this utility model directly improves the continuity and accuracy of the subsequent ceiling nail injection molding process, thereby effectively improving the overall processing efficiency.

[0022] (4) When the magnetic beads of this utility model enter the nail hole, they can be arranged for the first time during manual nailing, attracting the nails so that the nails are arranged one-to-one with the nail hole, forming a matrix arrangement.

[0023] (5) The magnetic beads of this utility model can attract nails that are close to them, but cannot ensure that they are attracted to the center of the nail hole. Therefore, the nail holding hole formed after the left and right clamps are closed has different functions in the whole process. For example, it first corrects the deviation when laying out the layout, then holds the material when feeding, and finally guides the material when transferring it.

[0024] (6) After the nail is transferred to the mold, the anti-misalignment feeding device is directly removed. The magnetic bead will pull the nail out and bring it back. Therefore, the ejector pin should push the magnetic bead to the edge of the nail holding hole so that the nail is blocked outside the nail holding hole by its own tail cap (the diameter of the nail holding hole after assembly is smaller than the nail tail cap, and the diameter of the nail holding hole after assembly matches the diameter of the nail shaft, ejector pin and magnetic bead). After that, the ejector pin resets with the magnetic bead, and the magnetic bead slowly moves away from the nail and loses its adsorption force, so that the anti-misalignment feeding device can be smoothly removed without affecting the state of the nail on the mold.

Detailed Implementation

[0027] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0028] Example 1: As Figure 1 and Figure 2 As shown, a feeding device for preventing misalignment and offset in batch injection molding of ceiling nails includes a base plate 1. A panel 3 is connected to the base plate 1 by four connecting posts 2, which are parallel to and separated from the panel 3 by space. The four connecting posts 2 are located at the four corners of the base plate 1 and the panel 3.

[0029] like Figure 3 and Figure 4 As shown, panel 3 has 128 pin holes 4 arranged in a matrix. Each pin hole 4 has a pin 5 extending into or out of it. Each pin 5 has a magnetic bead 6 on its free end. All pins 5 are mounted on a pin plate 7. The pin plate 7 and all pins 5 are located in the space between the base plate 1 and panel 3. A push-pull cylinder 8 is located at the center of the exposed end face of the base plate 1. The cylinder shaft of the push-pull cylinder 8 passes through the base plate 1 and is connected to the pin plate 7.

[0030] like Figure 5 As shown, four alignment pins 24 are arranged side by side in the center of panel 3, and each alignment pin 24 protrudes out of the plane where the fixture is located.

[0031] Panel 3 is provided with eight pairs of long strip-shaped clamps. Each pair of clamps is divided in half along its center line into a left clamping plate 10 and a right clamping plate 11. Each pair of left clamping plates 10 and right clamping plates 11 is joined together with a row of nail-holding holes 12 arranged at equal intervals along the length of their joint. Each row of nail-holding holes 12 corresponds to a row of nail-holding holes 4, so that each nail-holding hole 12 corresponds to a nail-holding hole 4. All left clamping plates 10 are connected to a pair of left linkage rods 13. The two left linkage rods 13 are connected to a left push-pull rod 14. The rear center of the left push-pull rod 14 is connected to the cylinder shaft of a left push-pull cylinder 15. The right clamping plates 11 are connected to a pair of right linkage rods 16. The two right linkage rods 16 are connected to a right push-pull rod 17. The rear center of the right push-pull rod 17 is connected to the cylinder shaft of a right push-pull cylinder 18.

[0032] Each left clamping plate 10 is provided with four left sliding rod holes, each corresponding to one of the two left linkage rods 13 and two right linkage rods 16, which pass through and maintain their respective sliding gaps. Each of the two left linkage rods 13 is fitted with eight left retaining rings 19, the same number as the left clamping plates 10, and arranged at equal intervals. Each left retaining ring 19 is connected to one of the left clamping plates 10 by a left spring 20. Each right clamping plate 11 is provided with four right sliding rod holes, each corresponding to one of the two left linkage rods 13 and two right linkage rods 16, which pass through and maintain their respective sliding gaps. Each of the two right linkage rods 16 is fitted with a number of right retaining rings 21, the same number as the right clamping plates 11, and arranged at equal intervals. Each right retaining ring 21 is connected to one of the right clamping plates 11 by a right spring 22.

[0033] Each row of pin holes 4 has a positioning pin 9 on both sides, and each row of pin holes 12 has a positioning hole 23 on both sides. The positioning pins 9 and the positioning holes 23 are in one-to-one correspondence and cooperate with each other.

[0034] Example 2: The above-mentioned clamp, left clamp 10, right clamp 11, left linkage rod 13, left push-pull rod 14, left push-pull cylinder 15, right linkage rod 16, right push-pull rod 17 and right push-pull cylinder 18 are regarded as a whole set of anti-misalignment and offset mechanism. Two sets of anti-misalignment and offset mechanism are arranged side by side on the panel 2.

[0035] The rest is the same as in Example 1.

[0036] Application: A feeding method for a feeding device for batch layout and injection molding of ceiling nails to prevent misalignment and offset includes the following steps: Step 1, Initial state: The lower push-pull cylinder, left push-pull cylinder, and right push-pull cylinder are all in the retracted state of the cylinder shaft. The needle plate is against the base plate, and the ejector pin with the magnetic bead is retracted in the gap space between the base plate and the panel, and is not inserted into the corresponding pin 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 clamping plate and the right clamping plate are separated, and the pin holding hole is open. Step two: Start the operation. 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. Stop if it does not penetrate. Then manually arrange the nails. As long as the nail is placed near the corresponding nail hole, the magnetic bead will attract the nail into place. Even if there are a few nails that are slightly off-center, ignore them for now. Step 3: The left and right push-pull cylinders start simultaneously, pushing the left and right push-pull rods towards each other to bring them together. Then, the left linkage rod slowly overcomes the spring force to push the left clamping plate, and the right linkage rod slowly overcomes the spring force to push the right clamping plate, closing the left and right clamping plates together. The positioning pins and positioning holes are used to position them in an orderly manner. During this process, the nail clamping holes and nail matching holes are aligned one by one, and the nail clamping holes also slowly adjust those nails that have deviated, ensuring that the nails always maintain the preset layout position (to explain, the tail cap of the nail is larger than the closing hole of the nail clamping hole, the nail shaft is clamped by the nail clamping hole, and the tail cap is between the nail clamping hole and the nail matching hole). Step 4: After completing the above nail layout, start feeding and transfer the material to the mold of the injection molding machine. The anti-misalignment feeding device of the present invention is transported to the side of the mold by an external robotic arm. The alignment pin and the alignment hole on the mold are used for alignment and matching. Then, the material is slowly brought closer so that the front end of the nail enters the mold first. Step 5: The left and right push-pull cylinders reset synchronously, pulling the left and right push-pull rods away from each other. Then, the left linkage rod pulls the left clamping plate with the help of the spring's reset force, and the right linkage rod pulls the right clamping plate with the help of the spring's reset force, separating the left and right clamping plates. At the same time, the lower push-pull cylinder pushes the ejector pin forward. When the end cap of the nail can pass through the nail holding hole, the ejector pin with the magnetic bead also protrudes from the nail holding hole, thus pushing the nail onto the mold. Step Six: Once the nails have fully reached the mold, the anti-misalignment feeding device of this invention is removed. The left and right push-pull cylinders are activated simultaneously, pushing the left and right push-pull rods towards each other. The left linkage rod then slowly overcomes the spring force to push the left clamping plate, and the right linkage rod slowly overcomes the spring force to push the right clamping plate, closing the left and right clamping plates. The nail-holding holes are then aligned one by one, with the nail-holding holes gripping the ejector pins, while the nails are blocked outside the holes by their caps. Next, the lower push-pull cylinder is activated to slowly reset, causing the ejector pins to retract and reset. The nails are blocked by the clamps, and the magnetic beads slowly move away from the nails, losing their adsorption force. The robot arm can then smoothly remove the anti-misalignment feeding device of this invention to prepare for the next nail feeding operation. The above steps are repeated.
