Description

Technical Field

[0001] This invention relates to the field of material transfer technology, and in particular to a horizontally pushed-in material receiving device. Background Technology

[0002] In automated assembly and material handling production lines, the directional transfer and attitude calibration of cylindrical geometric workpieces during the transfer process from the horizontal conveying station to the vertical lifting station are key processes that directly determine the operating efficiency and production stability of the entire production line. Strict requirements are placed on material alignment accuracy, attitude consistency and transfer stability.

[0003] Currently, the industry generally adopts a fixed through-hole pallet transfer solution for workstation transfer operations of this type of workpiece. This solution involves fixing multiple sets of pallet structures with positioning through holes on the production line frame. During operation, the cylindrical workpiece is inserted vertically into the positioning through holes from top to bottom by manual labor or a robot. The centering and limiting effect of the through holes ensures that the vertical posture of the workpiece is fixed. Then, the workstation is switched by the overall transfer of the pallets, thus providing a stable posture reference for subsequent processing and assembly processes.

[0004] However, this traditional structure has significant technical defects in actual mass production applications. On the one hand, to ensure the stability of the cylindrical workpiece during transport, the clearance between the through hole and the outer diameter of the workpiece is set to be extremely small. This makes the vertical insertion operation of the workpiece from top to bottom extremely demanding in terms of alignment accuracy, significantly increasing the difficulty of operation for both manual and robotic arms. It cannot adapt to the pace of high-speed automated production and is prone to unstable connection due to alignment deviations. On the other hand, affected by objective factors such as workpiece dimensional tolerances, surface oil contamination, machining burrs, and slight deformation under mass production conditions, frequent malfunctions such as jamming and incomplete insertion occur during the workpiece insertion process. This directly leads to abnormal posture problems such as workpiece tilting and centering axis misalignment, seriously affecting the operational accuracy and production continuity of subsequent processes. Summary of the Invention

[0005] The purpose of this invention is to provide a horizontally pushed-in material receiving device to solve the technical problems of difficult assembly and poor adaptability in existing fixed through-hole pallet transfer structures. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A horizontally pushed-in material receiving device includes a frame, a tray, and a material holding mechanism; The frame is used for fixed installation on material transfer or placement equipment; at least two of the trays are stacked along the height direction of the frame. Each of the pallets has at least two circumferentially oriented receiving slots for placing cylindrical materials. Each receiving slot has an opening that extends through the outside of the pallet, allowing the cylindrical material to be pushed horizontally into the receiving slot along the axial direction. The receiving slots on two adjacent pallets are coaxially arranged in a one-to-one correspondence. A set of material-holding mechanisms is symmetrically arranged on both sides of the opening of each receiving slot. The material-holding mechanisms are used to guide the cylindrical material into place and prevent the cylindrical material in the receiving slot from falling out and being limited.

[0007] Furthermore, the material-holding mechanism includes a thrust seat, a guide arm, a connecting rod, and a spring-loaded component; the thrust seat is fixed to the outer periphery of the tray, and the two ends of the connecting rod are respectively hinged to the thrust seat and the guide arm; the inner sidewalls of the two guide arms at the same slot form a guide surface, and the two guide surfaces cooperate to form a V-shaped material-guiding cut that is wider on the outside and narrower on the inside; the spring-loaded component is assembled between the thrust seat and the guide arm, and is used to drive the two guide arms to normally move closer to each other to maintain the V-shaped material-guiding structure, thereby realizing material introduction and limiting and preventing detachment.

[0008] Furthermore, the rebound component includes a rebound rod and a drive assembly; The rebound rod includes an integrally connected connecting part and a driving part arranged at an acute angle. The connecting part is equivalent to a connecting rod arranged between the thrust seat and the guide arm, and its two ends are respectively hinged to the thrust seat and the guide arm. The driving part is located between the connecting part and the connecting rod. The driving part is slidably assembled on the guide arm with the hinge point of the connecting part as the axis. The driving assembly is assembled between the thrust seat and the guide arm and is used to drive the driving part to slide along the guide arm and deflect away from the tray to reset when the two guide arms come together to reset.

[0009] Furthermore, the drive assembly includes a fixed base, a drive base, a telescopic rod, and a spring; The fixed seat is hinged to the thrust seat, and the guide arm has a through-hole groove. The drive seat is axially connected to the drive unit, and the connecting shaft of the two is slidably adapted to the slot. The telescopic rod is assembled between the fixed seat and the drive seat. The spring is sleeved on the outside of the telescopic rod, and its two ends abut against the drive seat and the fixed seat respectively. The spring normally pushes the drive seat, causing the drive unit to slide along the slot and rotate away from the tray. The linkage connection rotates and resets towards the opening of the receiving slot.

[0010] Furthermore, it also includes a blocking component, which is a positioning screw fixed to the tray. The positioning screw is provided corresponding to the connecting part of the rebound rod and is used to limit the rotation stroke of the connecting part to prevent the rebound rod from excessive deflection.

[0011] Furthermore, an open support plate is fixedly mounted on the bottom of the tray. The open support plate is adapted to the structural dimensions of the receiving groove and the opening, and is used to support the cylindrical material pushed into the receiving groove.

[0012] Furthermore, the guide arm is equipped with a guide assembly, which includes a guide seat fixed to the inside of the guide arm. The guide seat extends along the length of the guide surface to assist in guiding the cylindrical material to be smoothly pushed into the receiving groove.

[0013] Furthermore, the guiding assembly also includes a guiding shaft, which is fixed to the guiding seat and extends horizontally along the radial direction of the tray. The outer periphery of the guiding shaft protrudes from the surface of the guiding seat and forms a line-to-surface contact guide with the cylindrical material.

[0014] Furthermore, it also includes at least one set of support mechanisms, which are fixed to the bottom of the frame and disposed below the corresponding receiving slot; The support mechanism includes an electric cylinder, a support base, and a support shaft; the electric cylinder is fixedly installed at the bottom of the frame, and the support shaft connects the piston rod of the electric cylinder and the support base. The electric cylinder can drive the support base to extend and retract in the vertical direction to support and limit the cylindrical material in the receiving groove from below.

[0015] Furthermore, the support mechanism also includes a guide seat, a guide shaft, a guide sleeve, and a guide bearing; the guide seat is fixed to the frame, and the guide shaft is fixed to the guide seat parallel to the extension and retraction direction of the electric cylinder piston rod; the guide sleeve is slidably sleeved on the outside of the guide shaft through the guide bearing, and the guide sleeve is fixedly connected to the support seat to guide the extension and retraction movement of the support seat.

[0016] This invention discloses a horizontally pushed-in material receiving device, aiming to solve the technical problems of existing fixed through-hole tray transfer structures, such as high assembly difficulty, easy workpiece jamming and misalignment, and poor adaptability. This invention significantly reduces the alignment difficulty through horizontally pushed-in feeding, adapting to the high-speed production cycle of the production line; it eliminates the small-gap through-hole positioning structure, effectively improving the mass production error tolerance rate, and avoiding jamming and posture deviation problems caused by workpiece dimensional tolerances, surface burrs, oil stains, and slight deformation. At the same time, it relies on a double-sided symmetrical material holding mechanism to achieve automatic centering guidance and stable limiting, preventing workpiece loosening and deviation during transfer, and effectively improving the stability of material operation.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0024] Example 1 Reference Figure 1 and Figure 2 As shown in the figure, this embodiment specifically discloses a horizontal push-in material receiving device. The overall structure mainly includes a frame 100, a tray 200, an open tray 230, and a material holding mechanism 300. It can effectively solve the problems of difficult alignment, easy jamming, large posture deviation, and poor adaptability of the traditional vertical plug-in through-hole tray 200, and adapt to the production needs of efficient and stable transfer of cylindrical workpieces from horizontal conveying to vertical lifting station.

[0025] The frame 100 serves as the overall load-bearing mounting base, equipped with a frame shaft and a base. The frame shaft is vertically fixed to the end face of the base, ensuring that the axis of the frame shaft is perpendicular to the plane of the base. This results in good overall structural rigidity and stable installation. The frame 100 allows the receiving device to be fixedly installed on material transfer or placement equipment, ensuring no offset or shaking during the overall operation of the equipment and providing a stable installation foundation for subsequent high-precision material receiving and transfer.

[0026] At least two trays 200 are stacked along the vertical axis of the frame shaft, and multiple sets of trays 200 are evenly arranged along the height of the frame shaft, resulting in a regular structural layout and uniform stress distribution. Each tray 200 has at least two receiving slots 210 evenly distributed along its circumference for individually positioning and placing cylindrical materials; at the same time, the receiving slots 210 of the upper and lower corresponding trays 200 are coaxially aligned and matched along the frame shaft axis. This coaxial alignment structure ensures that the cylindrical materials are placed in a uniform posture and with consistent axes, preventing misalignment of the trays 200 from interfering with the placement of the cylindrical materials.

[0027] Each receiving slot 210 has an open slot 220 on the outer side of the tray 200. Unlike the traditional closed through-hole structure, this eliminates the need for a high-precision vertical insertion structure, allowing cylindrical materials to be pre-positioned vertically and parallel to the support shaft. The materials are then horizontally pushed into the receiving slot 210 radially along the support shaft through the outer slot 220 to complete their placement. This horizontal pushing-in feeding method eliminates the need for strict vertical alignment, greatly reducing the difficulty of robotic or manual alignment operations. It is suitable for high-speed production lines and completely avoids problems such as insertion jamming, incomplete placement, and workpiece tilting caused by workpiece tolerances, burrs, oil stains, and micro-deformation in traditional small-gap through-hole structures. This significantly improves mass production tolerance and material transfer stability.

[0028] An open tray 230 is fixedly mounted on the bottom of the pallet 200. The outline dimensions of the open tray 230 are perfectly matched with those of the receiving groove 210 and the outer groove 220. It is integrally fixed to the bottom of the pallet 200, forming a reinforcing structure similar to a reinforcing rib. This structure effectively improves the overall structural rigidity and flatness of the pallet 200, preventing deformation and warping during long-term material handling, high-speed transport, and lifting / reciprocating operations. It also eliminates problems such as misalignment of the receiving groove 210 and deviation in material placement caused by pallet 200 deformation, ensuring the structural stability and dimensional accuracy of the pallet 200 during long-term operation and effectively extending the service life of the device.

[0029] The open pallet 230 can provide full circumferential support for the horizontally pushed cylindrical material from the bottom, preventing the material from being suspended at the bottom or tilted under force, further ensuring the vertical posture accuracy of the workpiece after placement, effectively preventing the material from falling or tilting, and improving the overall stability of the material transfer process.

[0030] Each receiving tank 210 is equipped with a set of material-holding mechanisms 300 at the opening 220. Each set contains two material-holding mechanisms 300, symmetrically arranged on the left and right sides of the opening 220. The symmetrically arranged material-holding mechanisms 300 on both sides can automatically guide and center the material during the material feeding process, assisting in the smooth feeding of the material into the receiving tank 210. After the material is in place, the material-holding mechanisms 300 on both sides can form a lateral limiting constraint, effectively preventing the columnar material from falling out of the opening 220 or shifting during equipment transfer, lifting and vibration, and continuously ensuring the stability of the material posture.

[0031] Example 2 This embodiment is a further optimization based on embodiment 1, by adding a support mechanism 400 to provide precise vertical support for the cylindrical material during the process of removing the cylindrical material from the receiving device.

[0032] Reference Figure 2 and Figure 3 As shown, specifically, the support mechanism 400 is fixedly installed on the base of the frame 100, and the number of support mechanisms 400 corresponds one-to-one with the number of receiving slots 210 of a single pallet 200; along the vertical axial direction of the frame axis, a set of support mechanisms 400 is independently arranged directly below each receiving slot 210 to achieve a precise alignment layout of single slot single support, ensuring that each material station can obtain an independent and precise vertical support benchmark.

[0033] The support mechanism 400 includes an electric cylinder 410, a support base 420, a support shaft 430, a connecting plate 480, and a guide assembly. The electric cylinder 410 is fixedly mounted on the upper surface of the base. The piston rod axis of the electric cylinder 410 is coaxially aligned with the central axis of the corresponding receiving groove 210, and the piston rod can reciprocate in a vertical direction, moving closer to or further away from the receiving groove 210, providing stable power output for material lifting and unloading.

[0034] The support base 420 is fixedly connected to the end of the piston rod of the electric cylinder 410 via the support shaft 430. The radial dimension of the support base 420 is larger than the radial width of the piston rod of the electric cylinder 410, which effectively expands the material support contact area and can stably support the workpiece from the bottom of the cylindrical material. This avoids stress concentration and workpiece bottom pressure damage caused by single-point contact of the piston rod, and at the same time greatly improves the stability of the top support, preventing the workpiece from shaking or tipping during the material handling process.

[0035] Two sets of guide components are symmetrically arranged on both sides of the electric cylinder 410. The two sets of guide components are fixedly connected to the support base 420 through the connecting plate 480 to form a double-sided symmetrical guide constraint structure, which effectively counteracts the lateral clearance sway generated during the extension and retraction of the electric cylinder 410, and ensures that the support base 420 runs smoothly and without swaying.

[0036] Specifically, the guide assembly includes a guide seat 440, a guide shaft 450, a guide sleeve 460, and a guide bearing 470. The guide seat 440 is fixedly mounted on the base, and the guide shaft 450 is fixedly assembled on the guide seat 440. The axial direction of the guide shaft 450 is parallel to the central axis of the receiving groove 210, ensuring that the direction of guide movement is completely consistent with the direction of top support operation. The guide sleeve 460 is slidably assembled on the outside of the guide shaft 450 through the guide bearing 470, ensuring smooth sliding and low frictional resistance. The guide sleeve 460 is also fixedly integrated with the connecting plate 480.

[0037] During the process of the electric cylinder 410 driving the support seat 420 to extend and retract, the guide sleeve 460 slides precisely along the guide shaft 450, which can restrict and guide the movement trajectory of the support seat 420 throughout the process, eliminating problems such as offset, jamming, and tilting of the support seat 420, and ensuring the stability of the material top support discharge and vertical material picking process.

[0038] Example 3 This embodiment further defines the material-holding mechanism 300 structure in Embodiment 1. By using a four-bar elastic reset structure, it achieves adaptive material introduction and normal closed limiting, solving the defects of traditional rigid positioning structure such as high feeding difficulty, low fault tolerance, easy jamming, and lack of adaptive compensation. This further improves the smoothness of horizontal push-in feeding and the stability of material anti-detachment after positioning.

[0039] Reference Figure 4 and Figure 5As shown, specifically, the material-holding mechanism 300 includes a thrust seat 310, a guide arm 340, a connecting rod 320, and a springback component. The thrust seat 310 is fixedly installed on the outer periphery of the pallet 200, serving as a fixed reference for the overall material-holding mechanism 300, ensuring structural assembly accuracy and operational stability. Two connecting rods 320 are provided and respectively arranged on the upper and lower sides of the thrust seat 310. The two ends of the connecting rods 320 are hinged to the thrust seat 310 and the guide arm 340, respectively, and the two sets of hinge positions are coaxially arranged to ensure uniform force distribution during the rotation of the guide arm 340.

[0040] Two sets of material-holding mechanisms 300 are symmetrically arranged at the slot opening 220 of the same receiving groove 210. The guide arms 340 of the two sets of material-holding mechanisms 300 form guide surfaces opposite to the inner sidewalls. The spring-loaded assembly is assembled between the thrust seat 310 and the guide arms 340, and can normally drive the guide arms 340 on both sides to move towards the center of the slot opening 220 and close, so that the guide surfaces on both sides stably form a V-shaped material guide cut that is wider on the outside and narrower on the inside. This V-shaped guide structure with a large opening has automatic centering and correction capabilities, which can effectively reduce the alignment accuracy requirements of horizontally pushed materials, allowing materials with slight alignment deviations to be smoothly introduced into the groove. It is suitable for mass production conditions such as workpiece size tolerances, slight deformations, and surface oil stains, and greatly improves the feeding error tolerance.

[0041] During the horizontal material feeding operation, the outer wall of the cylindrical workpiece presses against the V-shaped guide surface, overcoming the elastic preload of the springback component and forcing the guide arms 340 on both sides to open outward, allowing the workpiece to smoothly enter the groove. Once the workpiece is fully pushed into the receiving groove 210 and in place, the external pressure disappears, and the springback component drives the guide arms 340 and connecting rod to quickly reset. The guide arms 340 on both sides then close again, using the V-shaped structure to seal the groove opening 220, forming a lateral limiting constraint on the cylindrical workpiece in the receiving groove 210. This effectively prevents the material from loosening, shifting, or jumping out during transfer, lifting, and vibration, ensuring a constant workpiece posture.

[0042] In this embodiment, the rebound component includes a rebound rod 330 and a drive assembly. The rebound rod 330 consists of an integrally formed connecting part 331 and a drive part 332 arranged at an acute angle, exhibiting strong overall structural integrity, high transmission accuracy, and resistance to deformation. The connecting part 331 is positioned between the thrust seat 310 and the guide arm 340, with both ends hinged together. The drive part 332 is slidably mounted on the guide arm 340. The rebound rod 330 is also symmetrically arranged vertically, and together with the connecting rod 320, forms a parallel four-bar linkage transmission structure with the thrust seat 310 as the fixed base point. This parallel four-bar linkage ensures smooth opening and closing of the guide arm 340, with a regular trajectory and no eccentricity or jamming, achieving high-precision, high-repeatability adaptive opening and closing movements.

[0043] The drive assembly includes a fixed base 390, a drive base 380, a telescopic rod, a spring 350, and a stopper 240. The fixed base 390 is hinged to the thrust base 310 and located between the hinged positions of the connecting rod 320 and the return rod 330. The guide arm 340 has a waist-shaped groove 341 extending through it along the thickness direction. The drive base 380 and the drive part 332 of the return rod 330 are axially connected, and the connecting shaft slides within the waist-shaped groove 341 to achieve adaptive sliding adjustment of the drive part 332. The telescopic rod is assembled between the fixed seat 390 and the drive seat 380. The spring 350 is sleeved on the outside of the telescopic rod. The two ends of the spring 350 abut against the drive seat 380 and the fixed seat 390 respectively. The spring 350 is normally kept in a slightly compressed and pre-tightened state, which can continuously push the drive seat 380 and drive the drive part 332 to slide along the waist groove 341 away from the tray 200. In conjunction with the rebound rod 330 structure, it maintains the normal closed state of the guide arms 340 on both sides and the stable formation of the V-shaped cut, ensuring the reliability of the normal limit.

[0044] Based on the aforementioned structural linkage, during installation, the rebound rod 330 is positioned relative to the connecting rod 320 on the side closer to the slot 220. Thus, when the drive unit 332 is pushed away from the tray 200 by the spring 350, it can cause the rebound rod 330 to deflect around the hinge point of the connecting part 331, thereby pulling the connecting part 331 to rotate towards the slot 220 around the hinge point of the thrust seat 310. This keeps the guide arms 340 on both sides constantly moving closer together, ensuring the slot 220 is closed and limited under normal conditions. To prevent excessive rotation of the rebound rod 330 and structural over-displacement failure, a positioning screw 240 is fixedly installed on the tray 200 as a blocking element. This precisely limits the maximum rotation stroke of the connecting part 331, providing mechanical limit protection and improving the operational safety and structural durability of the mechanism.

[0045] During material feeding, the workpiece's squeezing force drives the connecting part 331 to rotate in the opposite direction, causing the connecting rod 320 to swing synchronously, thus stabilizing the opening of the guide arm 340. Simultaneously, the driving part 332 deflects with the connecting part 331 and slides along the waist-shaped groove 341 of the guide arm 340 towards the tray 200, further compressing the energy stored in the spring 350. The entire opening and closing process is flexible and buffered, without rigid impact, effectively preventing workpiece squeezing, bumping, jamming, and scratching. When the workpiece is fully inserted into the slot, the squeezing force is released, and the spring 350 releases its elastic potential energy to drive the connecting rods, the rebound rod 330, and the guide arm 340 to quickly reset, closing the slot 220 again to complete the limit. This achieves an automatic flexible material guiding and limiting effect with adaptive opening during feeding and automatic locking upon positioning, significantly improving the automation level and operational stability of the equipment.

[0046] Each guide arm 340 is equipped with a guide assembly to assist in guiding cylindrical materials smoothly into the receiving tank 210 and to work with the material holding mechanism 300 to prevent materials from falling out. The guide assembly includes a guide seat 360 and a guide shaft 370. The guide seat 360 extends along the length of the guide surface, with a long guide stroke and a wide coverage area, which can ensure that the material is guided smoothly throughout the entire process.

[0047] The guide shaft 370 is fixedly mounted on the guide seat 360, and the guide shaft 370 is arranged horizontally along the radial direction of the tray 200. The outer periphery of the guide shaft 370 protrudes from the surface of the guide seat 360, so that the material is pushed in and forms a stable line-to-surface contact guide with the guide shaft 370. Compared with the traditional surface contact guide structure, this line-to-surface contact method can significantly reduce the frictional resistance of the material being pushed in, avoid scratches and jamming on the workpiece surface, and effectively avoid the problem of unsmooth guidance caused by oil stains and burrs on the workpiece surface, further improving the smoothness of material feeding and the structural fault tolerance.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
