Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, specifically to a slide rail feeding device. Background Technology

[0002] In the field of automated assembly, stable and orderly workpiece feeding is a key factor in ensuring the efficient operation of the production line. Especially for the automated assembly of long, sheet-like parts, a feeding structure that can adaptively adjust according to parameters such as workpiece length and thickness is required. This ensures that the parts maintain a fixed posture and achieve precise positioning during transport, thereby meeting the assembly needs of different product lines. Such a structure must balance conveying stability with adjustment flexibility to cope with multi-variety, small-batch production models.

[0003] Existing feeding devices generally suffer from insufficient adaptability when handling long, sheet-like parts. Fixed limiting structures are difficult to accommodate parts of different lengths, while single-height limiting designs cannot adapt to workpieces with significant thickness variations. This leads to deviations, jamming, or positioning errors during transport, directly impacting assembly accuracy and production efficiency. Consequently, each time a product is changed, the production line equipment needs to be replaced simultaneously. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a slide rail feeding device to solve the technical problem of how to transport long sheet-like parts and enable the equipment to adapt to parts of different lengths and thicknesses.

[0005] The technical solution adopted in this utility model is: a slide rail feeding device, comprising: Conveyor belt, side limit strips, and top limit strip; On the outer side of the starting end of the conveyor belt, the top edge of the frame is aligned with the top edge of the conveyor belt. A pushing mechanism is provided on the side of the frame, and the pushing direction is along the conveyor belt transport direction. Two sets of side limiting strips are respectively set on both sides of the conveyor belt transport direction, and the relative distance between the two sets of side limiting strips can be adjusted. The top limiting strip is set on the upper side of the conveyor belt, and the length of the top limiting strip is along the conveyor belt transport direction. The distance between the lowest surface of the top limiting strip and the upper surface of the conveyor belt can also be adjusted.

[0006] Optionally, the conveyor belt includes: a support plate connected to the frame, a drive pulley and a driven pulley respectively disposed at both ends of the support plate, and a belt body connected to the drive pulley and the driven pulley, wherein the upper surface of the belt body is higher than other parts of the conveyor belt; the conveyor belt is arranged in two sets opposite to each other.

[0007] Optionally, the two sets of side limiting strips are respectively disposed on the outer side of the two sets of conveyor belts. On the same side, the side limiting strips are slidably connected to the bearing plate and the sliding position can be adjusted, with the sliding direction along the width direction of the conveyor belt.

[0008] Optionally, frame plates are provided on both sides of the conveyor belt, and on the same side, the side limiting strip is slidably connected to the frame plate, with the sliding direction along the width direction of the conveyor belt.

[0009] Optionally, the two sets of side limiting strips are penetrated by the same threaded rod, and the threads on both sides of the threaded rod have opposite directions. The threaded rod is also connected to the frame and can rotate along the width direction of the conveyor belt.

[0010] Optionally, it also includes a transition block, the mounting section of which is connected to the side limiting strip, the hanging section extending into the area above the conveyor belt, the top limiting strip being hung below the hanging section along the conveyor belt transport direction, and the mounting height of the hanging section being adjustable.

[0011] Optionally, the mounting section is provided with a vertical hole, the top limiting strip is a cylindrical rod, and the top limiting strip is provided with a radial screw hole. The vertical hole and the screw hole can be aligned and tightened by bolts.

[0015] As can be seen from the above technical solution, the beneficial technical effects of this utility model are as follows: This slide rail feeding device, through its adjustable side and top limit bars, achieves precise adaptation to long, sheet-like parts of varying lengths and thicknesses. The adjustable spacing of the side limit bars accommodates parts of various lengths, preventing misalignment; the adjustable height of the top limit bar adapts to workpieces of different thicknesses, ensuring stable conveying.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] This device is primarily used in the assembly of drawer slides, which are commonly used in drawers. The slide structure consists of outer, middle, and inner rails, which work together to ensure smooth drawer movement. During assembly, this device precisely delivers and positions the slide slide components, ensuring high efficiency and accuracy. Drawer sizes vary, and therefore the dimensions of the slide slide components also vary, but generally, these components are long, flat strips with varying thicknesses and lengths.

[0026] Please refer to the attached document for details regarding this slide rail feeding device. Figure 1 One possible implementation method is as follows: Conveyor belt 1, side limiting strip 2, and top limiting strip 3; On the outer side of the starting end of conveyor belt 1, the top edge of the frame is aligned with the top edge of conveyor belt 1. A pushing mechanism 4 is provided on the side of the frame. The pushing mechanism 4 can be driven by a cylinder. After the cylinder telescopic shaft passes through the frame structure, it inserts into the outer area of ​​the starting end of conveyor belt 1. The workpiece 8 fed in by the material inlet channel 9 is located in this area and is pushed. The pushing direction is along the transport direction of conveyor belt 1. Two sets of side limiting strips 2 are respectively set on both sides of the transport direction of conveyor belt 1. The relative distance between the two sets of side limiting strips 2 can be adjusted to accommodate workpieces 8 of different lengths. The top limiting strip 3 is set on the upper side of conveyor belt 1. The length of the top limiting strip 3 is along the transport direction of conveyor belt 1. The distance between the lowest surface of the top limiting strip 3 and the upper surface of conveyor belt 1 can also be adjusted to accommodate workpieces 8 of different thicknesses.

[0027] The working process of the above embodiments is as follows, please refer to... Figure 1 Workpiece 8 was transported from other equipment by... Figure 1 The incoming material channel 9 feeds the material into the outer side of the starting end of the conveyor belt 1, located at the top edge of the frame and aligned with the height of the conveyor belt 1. Then, the pushing mechanism 4 pushes the workpiece 8 onto the upper surface of the conveyor belt 1. Subsequently, the multiple workpieces 8 are arranged neatly by the transport of the conveyor belt 1, facilitating subsequent production processes (such as packaging or continuing other production). During this process, the opposite sides of the two sets of side limiting strips 2 abut against the two ends of the workpiece 8 in the length direction, and the two sets of top limiting strips 3 abut against the upper surfaces of the two ends of the workpiece 8. At the same time, the bottom of the workpiece 8 is supported by the conveyor belt, and the front and rear sides of the workpiece 8 in the conveying direction are abutted by adjacent workpieces 8. Therefore, for a single workpiece 8, all directions are restricted, and it can only be laid flat on the conveyor belt in a specific posture.

[0028] This sliding rail feeding device significantly improves the flexibility and stability of conveying long, sheet-like workpieces. Its core advantages lie in: the adjustable two sets of side limiting strips 2 allow for flexible spacing adjustments based on workpiece length, ensuring alignment of workpieces of different specifications during transport and effectively preventing offset or jamming due to length differences; the height-adjustable top limiting strip 3 precisely adapts to workpieces 8 of varying thicknesses, and together with the conveyor belt's support for the bottom of workpiece 8, forms a three-dimensional limiting system, stably constraining the workpieces in the transport direction, width direction, and vertical direction, achieving precise positioning for flat arrangement. Furthermore, the pushing mechanism located on the outer side of the conveyor belt's starting end smoothly pushes the workpiece from the infeed channel into the conveyor belt, naturally contacting subsequent workpieces, ensuring continuous feeding and further enhancing the neatness of the arrangement. This device features a simple structure and convenient adjustment, quickly adapting to the production needs of multiple varieties and small batches, providing an efficient and stable feeding solution for automated assembly lines, significantly reducing equipment modification costs and production debugging time.

[0029] In one possible implementation, see Appendix Figure 1The conveyor belt 1 includes: a support plate 11 connected to the frame; a drive pulley 12 and a driven pulley 13 respectively located at both ends of the support plate 11; the drive pulley 12 can be driven by a motor; and a belt body 14 connected to the drive pulley 12 and the driven pulley 13. The upper surface of the belt body 14 is higher than other parts of the conveyor belt 1 to ensure that the workpiece 8 only contacts the belt body, reducing frictional resistance. The support plate 11 is also provided with a laterally protruding support plate 111, which supports the bottom surface of the upper belt body 14. The conveyor belt 1 is arranged in two sets, supporting the workpiece 8 from both sides. This avoids tilting or offset caused by unilateral force, and is especially suitable for the stable conveying of long sheet-shaped workpieces, providing a reliable guarantee for subsequent precise positioning and assembly.

[0030] In one possible implementation, two sets of side limiting strips 2 are respectively disposed on the outer sides of the two sets of conveyor belts 1. On the same side, the side limiting strips 2 are slidably connected to the bearing plate 11 and the sliding position can be adjusted. The sliding direction is along the width direction of the conveyor belt. For example, they are guided to slide by a smooth rod. The bearing plate 11 is fixed to the smooth rod, and the side limiting strips 2 slide with the smooth rod. Then, they are connected by a screw parallel to the smooth rod. The end of the screw is unthreaded and rotatably connected to the bearing plate 11 of the conveyor belt 1. The middle part of the screw is threadedly connected to the side limiting strips 2. When the screw is rotated, the side limiting strips 2 can move along the axis of the smooth rod, thereby adjusting the distance between the side limiting strips 2 and the bearing plate 11. The distance between the two side limiting strips 2 and the bearing plate 11 can be adjusted separately.

[0031] As an alternative to the above embodiments, in one possible implementation, frame plates 5 are provided on both sides of the conveyor belt 1. On the same side, a side limiting strip 2 is slidably connected to the frame plate 5, and the sliding direction is along the width direction of the conveyor belt. The width adjustment method of the side limiting strip 2 and the frame plate 5 can be the same as the previous embodiment, that is, adjustment is made using a guide rod and a screw.

[0032] As a more preferred embodiment, in one possible implementation, see Appendix Figure 4 The two sets of side limiting strips 2 are pierced by the same threaded rod. The threaded rod is along the width direction of the conveyor belt, and the threads on both sides of the threaded rod are in opposite directions. The threaded rod is also connected to the frame and can rotate. When the threaded rod is turned, the side limiting strips 2 on both sides can move synchronously in opposite directions. The advantage is that the center of symmetry of the two sets of side limiting strips 2 remains unchanged.

[0033] The common technical effects of the above solutions can be summarized as follows: all of them achieve the adjustable position function of the side limit bar 2, which can flexibly adjust the limit distance on both sides according to the workpieces 8 of different lengths and specifications, ensuring that the workpieces maintain precise alignment during the conveying process and effectively avoiding offset or jamming; at the same time, all of them use mechanical transmission components (screws / threaded rods) as driving elements, which not only ensures the stability and reliability of adjustment, but also reduces the complexity of operation through structural optimization, ultimately providing a highly compatible and precise lateral limit solution for the automated conveying of long sheet-shaped workpieces.

[0034] In one possible implementation, see Appendix Figure 5 It also includes an adapter block 21, the mounting section 211 of which is connected to the side limiting strip 2, the hanging section 212 extending into the area above the conveyor belt 1, and the top limiting strip 3 hanging below the hanging section 212 along the transport direction of the conveyor belt 1. The installation height of the hanging section 212 is adjustable. In one embodiment, the mounting section 211 and the hanging section 212 are an integral structure, with the mounting section 211 having a vertical through slot and the side limiting strip 2 having a threaded hole, allowing adjustment of the installation height of the mounting section 211 relative to the side limiting strip 2. In another embodiment, the mounting section 211 and the hanging section 212 are separate structures, with the mounting section 211 having a vertical through slot and the hanging section 212 having a threaded hole, allowing adjustment of the installation height of the mounting section 211 relative to the hanging section 212. The hanging section 212 has a vertical hole, and the top limiting strip 3 is a cylindrical rod with radial threaded holes. The vertical hole and the threaded holes can be aligned and tightened with bolts. The cylindrical rod presses against the surface of workpiece 8, and there is line contact between them, resulting in relatively small frictional force.

[0035] The above embodiments not only ensure structural stability, but also enable the top limiting strip 3 to abut against the surface of the workpiece 8 in a line contact manner, which significantly reduces frictional resistance. At the same time, the height adjustment function can accurately adapt to workpieces of different thicknesses, and together with the side limiting strip 2, they form a three-dimensional limiting system, which improves the stability and compatibility of the conveying.

[0036] In one possible implementation, see Appendix Figure 2 On the outer side of the starting end of conveyor belt 1, a top limiting block 6 is provided on the upper side of the pushing area of ​​the pushing mechanism 4. The distance between the bottom surface of the top limiting block 6 and the top surface of the corresponding area of ​​the frame can be adjusted to match the thickness of the conveyed workpiece. (See reference...) Figure 2 It can also be adjusted by slots and screws. The frame side is provided with threads, and the top limit block 6 is provided with a strip-shaped slot and is tightened by screws. The top limit block 6 has a guide slope 61 on one side along the width direction of the conveyor belt 1.

[0037] This implementation significantly improves the accuracy of workpiece 8's positioning and conveying stability through the design of the top limiting block 6: the gap between the bottom surface of the top limiting block 6 and the top surface of the frame precisely matches the thickness of the workpiece 8, forming a vertical limiting structure. This ensures that when the workpiece 8 enters from the material inlet channel 9, it can only be inserted into the gap in a flat position, avoiding jamming or overturning due to uneven force caused by height deviation. The guide slope 61 set on its side plays an automatic correction role during the insertion of the workpiece 8. Even if the workpiece 8 has a slight angular deviation, it will gradually adjust to a horizontal state under the guidance of the slope. Together with the horizontal thrust of the pushing mechanism 4, it forms a three-dimensional constraint, so that the workpiece 8 always maintains a stable posture during the force process, effectively preventing jumping or leaving the conveying path, and providing a reliable guarantee for subsequent accurate conveying and assembly.
