Description

Technical Field

[0001] This utility model mainly relates to the field of bone-fastening machine technology, specifically a material feeding and unloading device for a bone-fastening machine. Background Technology

[0002] Bone-fastening machines are widely used in the processing and forming of products such as metal cylinders and tin cans. Their workflow covers multiple stages, including taking sheet metal, pressing and shaping ribs, and forming bones. In the traditional bone-fastening machine operation mode, there are many problems that need to be solved in the material handling and unloading stage.

[0003] In the bone-fastening machine processing flow, the workpiece processed by the bone-fastening mold needs to be transferred from the mold's discharge end to a designated position. Currently, most operations rely on manual direct material handling or simple guide structures for assisted material handling. However, manual direct material handling not only requires continuous operator monitoring, resulting in high labor intensity, but also poses risks of workpiece damage due to improper control of force or positional deviations during manual grasping and transfer, especially when the workpiece is heavy. Furthermore, the intermittent nature of manual operation is difficult to match the continuous processing rhythm of the bone-fastening machine, frequently causing process interruptions and hindering overall work efficiency. Some bone-fastening machines use simple guide structures for assisted material handling, which can achieve initial reception of the workpiece from the mold to the guide rod. However, the guide rod only plays a basic guiding role. When the workpiece slides down the guide rod, it is prone to collision with the end of the guide rod or the receiving surface due to its own falling potential energy, resulting in workpiece damage and making it difficult to ensure the integrity of the processed workpiece. Utility Model Content

[0004] This utility model provides a solution that addresses the problem of overly simplistic existing solutions. It offers a significantly different approach, primarily providing a material handling and unloading device for a bone-fastening machine. This addresses the issue mentioned in the background section where finished workpieces from the die's discharge end need to be transferred to a designated location. Existing operations rely on manual material handling or simple guide structures. Manual handling requires continuous monitoring, is labor-intensive, easily damages workpieces, and is inconsistent with continuous processing rhythms, leading to frequent interruptions and reduced efficiency. While simple guide structures can support workpieces, they are easily damaged by potential energy collisions when slipping, making it difficult to maintain their integrity.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A material handling and feeding device for a bone-fastening machine includes a support assembly, on which a feeding assembly is mounted.

[0006] The support assembly includes a fixed tube, an L-shaped adjusting plate is slidably mounted on the inner wall of the fixed tube, and a sliding tube is slidably mounted on the L-shaped adjusting plate.

[0007] The feeding assembly includes an L-shaped fixing plate detachably connected to the mounting block. A first telescopic rod is installed through one end of the L-shaped fixing plate. The telescopic end of the first telescopic rod is connected to a mounting shell. A second telescopic rod is installed through the inner wall of the mounting shell, and the telescopic end of the second telescopic rod is connected to an adsorption structure.

[0008] More preferably, the bottom of the fixed tube is provided with a base plate, and the base plate is provided with round holes near the four corners. One end of the sliding tube is provided with a mounting block, and the mounting block is detachably connected to the L-shaped fixed plate by screws.

[0009] More preferably, the outer wall of the L-shaped adjusting plate is provided with a plurality of uniformly and equidistantly distributed elliptical holes, and both the fixed tube and the sliding tube are provided with elliptical holes that are adapted to the elliptical holes on the L-shaped adjusting plate, and the L-shaped adjusting plate is connected to the fixed tube and the sliding tube respectively by screws.

[0010] More preferably, the inner wall of the L-shaped fixing plate is provided with a slide rail, and the mounting shell is provided with a slider that slides with the slide rail.

[0011] More preferably, the inner wall of the mounting shell has symmetrically distributed circular holes, and a sliding rod is slidably mounted in the circular holes through a linear bearing, with one end of the sliding rod connected to the adsorption structure.

[0012] More preferably, the adsorption structure includes an adsorption frame, a connector, and vacuum suction cups. The connector is disposed on the adsorption frame, and multiple vacuum suction cups are provided, which are evenly and equidistantly distributed on the adsorption frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This material handling and unloading device, through an L-shaped adjusting plate, a fixed tube, and a sliding tube, with elliptical holes connecting them, allows for adjustment of the overall height and horizontal extension distance of the support components according to usage requirements. This ensures that the adsorption structure is precisely aligned with the workpiece gripping area on the guide rod, meeting the operational position requirements under different working conditions and improving the device's applicability. Furthermore, through the cylinder-driven double telescopic rod structure and PLC control logic, it achieves automated cycle operation, replacing manual labor. The evenly distributed multiple vacuum suction cups and sliding rod guide design together ensure the stability of the workpiece during transfer, avoiding deformation and damage caused by collisions.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0019] Please refer to the appendix carefully. Figures 1-3 A material handling and feeding device for a bone-fastening machine includes a support component 1, on which a feeding component 2 is provided.

[0020] The support assembly 1 includes a fixed tube 102, an L-shaped adjusting plate 103 is slidably mounted on the inner wall of the fixed tube 102, and a sliding tube 104 is slidably mounted on the L-shaped adjusting plate 103.

[0021] The feeding assembly 2 includes an L-shaped fixing plate 201 that is detachably connected to the mounting block 105. A first telescopic rod 203 is installed through one end of the L-shaped fixing plate 201. The telescopic end of the first telescopic rod 203 is connected to a mounting shell 204. A second telescopic rod 205 is installed through the inner wall of the mounting shell 204, and the telescopic end of the second telescopic rod 205 is connected to an adsorption structure 206.

[0022] Both the first telescopic rod 203 and the second telescopic rod 205 are cylinders, connected to the factory's air source via solenoid valves. The solenoid valves, vacuum generator, and magnetic proximity sensors mounted on the first telescopic rod 203 and the second telescopic rod 205 are electrically connected to the PLC control system to receive sensor signals and control the sequential movement of the cylinders and the start and stop of the vacuum suction cup.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a base plate 101 is provided at the bottom of the fixed tube 102, and round holes are provided at the four corners of the base plate 101. A mounting block 105 is provided at one end of the sliding tube 104, and the mounting block 105 is detachably connected to the L-shaped fixed plate 201 by screws. The round holes at the four corners of the base plate 101 facilitate the installation of the entire structure on the work platform or frame by bolts and other fasteners, improving the stability of the device during use. The sliding tube 104 is detachably connected to the L-shaped fixed plate 201 by screws through the mounting block 105, realizing the assembly and disassembly of the feeding component 2 and the support component 1, which is convenient for later maintenance.

[0024] In this embodiment, as Figure 2 As shown, the outer wall of the L-shaped adjusting plate 103 is provided with several evenly spaced elliptical holes, and both the fixed tube 102 and the sliding tube 104 are provided with elliptical holes that match the elliptical holes on the L-shaped adjusting plate 103. The L-shaped adjusting plate 103 is connected to the fixed tube 102 and the sliding tube 104 respectively by screws. The matching of the elliptical holes provides multiple relative position adjustments between the L-shaped adjusting plate 103 and the fixed tube 102 and the sliding tube 104. By installing the screws at the corresponding positions of the different elliptical holes, the extension length of the L-shaped adjusting plate 103 relative to the fixed tube 102 and the sliding position of the sliding tube 104 relative to the L-shaped adjusting plate 103 can be adjusted, thereby realizing the adjustment of the overall height and horizontal extension distance of the support assembly 1, thus meeting the requirements of the working position of the unloading assembly 2 under different working conditions and improving the applicability of the device.

[0025] In this embodiment, as Figure 3 As shown, the inner wall of the L-shaped fixing plate 201 is provided with a slide rail 202, and the mounting shell 204 is provided with a slider that slides in cooperation with the slide rail 202. The sliding cooperation between the slide rail 202 and the slider provides guidance for the movement of the mounting shell 204 along the L-shaped fixing plate 201, preventing it from deviating or shaking during movement, and improving the movement stability of the mounting shell 204 when the first telescopic rod 203 drives it.

[0026] In this embodiment, as Figure 3As shown, the inner wall of the mounting shell 204 has symmetrically distributed circular holes, and a slide rod 207 is slidably installed in the circular holes through a linear bearing. One end of the slide rod 207 is connected to the adsorption structure 206. The symmetrically distributed slide rod 207 forms a sliding fit with the mounting shell 204 through the linear bearing, providing guiding support for the movement of the adsorption structure 206, which can improve the movement stability of the adsorption structure 206 under the drive of the second telescopic rod 205.

[0027] In this embodiment, as Figure 3 As shown, the adsorption structure 206 includes an adsorption frame, a connector, and vacuum suction cups. The connector is located on the adsorption frame, and multiple vacuum suction cups are provided, which are evenly and equidistantly distributed on the adsorption frame. The even and equidistant distribution of multiple vacuum suction cups can form a relatively uniform adsorption force during adsorption operations, avoiding deformation or detachment of the adsorbed material due to uneven force, thus improving the stability and reliability of adsorption. The connector can be connected to an external vacuum generating device (such as a vacuum generator or vacuum pump) to provide negative pressure to multiple vacuum suction cups simultaneously. The vacuum generator is connected to the connector of the adsorption structure 206 through a PU tube. The adsorption frame is provided with a vacuum air passage, which connects multiple vacuum suction cups in parallel.

[0028] The specific operating procedure of this utility is as follows: First, fix the entire device to the guide rod of the automatic bone-fastening machine through the round holes at the four corners of the base plate 101, so that the adsorption structure 206 is above the guide rod and the guide rod is kept horizontal.

[0029] Next, by adjusting the relative positions of the L-shaped adjustment plate 103 with the fixed tube 102 and the sliding tube 104, and selecting elliptical holes at different positions for screw locking, the overall height and horizontal extension distance of the support assembly 1 are adjusted to ensure that the adsorption structure 206 is aligned with the workpiece gripping area on the guide rod.

[0030] When the automatic bone-fastening machine pushes the processed workpiece onto the guide rod, the control system starts the unloading process. The first telescopic rod 203 extends, driving the mounting shell 204 to slide to one side along the slide rail 202 of the L-shaped fixing plate 201, so that the adsorption structure 206 is close to the workpiece. Then the second telescopic rod 205 extends, and under the guidance and support of the slide rod 207, it drives the adsorption structure 206 to fit against the surface of the workpiece.

[0031] At this time, the vacuum generator connected to the control system sends negative pressure through the connector, causing multiple vacuum suction cups on the adsorption rack to generate adsorption force synchronously, and use the evenly distributed suction cups to grip the workpiece.

[0032] After the gripping is completed, the first telescopic rod 203 retracts, causing the workpiece to detach from the guide rod. Then, the first telescopic rod 203 continues to extend, moving the workpiece to the designated unloading position.

[0033] Upon reaching the unloading position, the vacuum generator stops providing negative pressure, the suction cup releases the workpiece, and the first telescopic rod 203 and the second telescopic rod 205 reset, waiting for the next workpiece push signal to complete one unloading cycle.

[0034] Throughout the process, sensors on the first telescopic rod 203 and the second telescopic rod 205 sense the distance in real time to ensure precise coordination of the actions of each component. The control system coordinates the driving of the cylinder and the start and stop of the vacuum device to realize automated material unloading operation, which is used to transfer the cylindrical metal workpiece processed by the bone-cutting machine from the horizontal guide rod to the adjacent conveyor belt or basket.

[0035] It should be noted that the automatic bone-fastening machine adapted to this utility model is an existing mature device. The guide rod is pre-installed at the discharge end of the bone-fastening mold of the automatic bone-fastening machine to receive the processed workpiece. Furthermore, the overall structure of the automatic bone-fastening machine and its transmission structure that automatically pushes the processed workpiece onto the guide rod are all mature technologies in the field of automatic bone-fastening machines and are not the improvement points of this utility model. Therefore, the specific structure and working principle of the automatic bone-fastening machine will not be described in detail here.

[0036] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
