Description

Technical Field

[0001] The present invention belongs to the field of automation, and particularly relates to an automatic feeding mechanism applied to an orthosis. Background Art

[0002] During the production process of an orthosis, precise and stable feeding of the plate is a key step.

[0003] Traditional feeding methods mostly rely on manual operation or simple mechanical devices, which are not only inefficient but also have many potential problems:

[0004] 1. Limitations of manual operation: Manual handling and placement of the plate not only involve high labor intensity but also make it difficult to ensure the consistency and accuracy of each operation. Especially in situations where high-precision positioning is required, manual operation is prone to introducing errors, affecting the quality of subsequent processing.

[0005] 2. Risks of plate offset and slipping: Whether it is manual or simple mechanical equipment, it is difficult to completely avoid the phenomenon of plate offset or slipping during the feeding process, and the plate is prone to being knocked or even damaged during the handling and conveying process. This situation not only causes material waste and increases costs but may also pose safety hazards.

[0006] Due to the above reasons, traditional feeding methods are inefficient and unreliable. Especially in a continuous production environment, any small error or delay may lead to the stagnation of the entire production line, seriously affecting the production plan and delivery time. Summary of the Invention

The suction attachment is used to adsorb the plate and restrict it on the support plate;

[0010] A conveying assembly is movably arranged in the frame, and the output end of the conveying assembly is connected to the lifting assembly to drive the lifting assembly to move along the length direction of the frame;

[0011] When the lifting assembly contracts into the frame, the sheet can be placed on the frame and located at the bottom end of the conveying space;

[0012] When the lifting assembly vertically lifts along the direction of the conveying space, there is a height difference between the sheet and the frame, so that the conveying assembly can convey the sheet along the length direction of the frame to the required position.

[0013] In the above automatic feeding mechanism applied to an orthosis, the lifting assembly further includes a moving plate and a lifting unit. The moving plate is arranged at the output end of the conveying assembly; the lifting unit is arranged on the moving plate, and a lifting bracket is connected to the driving end of the lifting unit. A plurality of the supporting plates and the suction accessories are installed on the lifting bracket.

[0014] In the above automatic feeding mechanism applied to an orthosis, a plurality of L-shaped extension plates are equidistantly distributed along the length direction of the lifting bracket. Each L-shaped extension plate is detachably provided with the suction accessory in the vertical direction, so that the suction end of the suction accessory is flush with the supporting plate.

[0015] In the above automatic feeding mechanism applied to an orthosis, the lifting unit includes a driving motor and a lifter both arranged on the moving plate. The driving motor is connected to the lifter through a transmission shaft, and a lifting rod is movably arranged in the lifter in the vertical direction. The top end of the lifting rod is connected to the lifting bracket.

[0016] In the above automatic feeding mechanism applied to an orthosis, each suction accessory is provided with an adjusting rod that movably penetrates through the L-shaped extension plate. A locking nut is detachably connected to the adjusting rod, and the locking nut is used to limit the relative movement of the adjusting rod with respect to the L-shaped extension plate.

[0017] In the above automatic feeding mechanism applied to an orthosis, the conveying assembly includes a driving member and a guide rail both arranged on the frame. The output end of the driving member is connected to the moving plate. The guide rail is arranged along the length direction of the frame. A guide block is arranged at the bottom end of the moving plate, and the guide block is movably clamped to the guide rail.

[0018] In the above automatic feeding mechanism applied to an orthosis, an inverted L-shaped limiting portion is further formed at the top end of the anti-disengagement frame, and the L-shaped limiting portion is used to limit the lifting height of the sheet relative to the frame.

[0019] In the above-mentioned automatic feeding mechanism applied to an orthosis, a fixing plate is arranged on the driving member, a locking block is arranged on the fixing plate, a locking hole is formed on the moving plate, and the locking block is movably inserted into the locking hole.

[0020] In the above-mentioned automatic feeding mechanism applied to an orthosis, a plurality of adjusting columns are movably arranged on the machine frame, a supporting foot is connected to the bottom end of each adjusting column, and when the plurality of supporting feet move relative to the machine frame, they can contact the ground, so that the machine frame maintains a horizontal posture.

[0021] In the above-mentioned automatic feeding mechanism applied to an orthosis, a plurality of rolling wheels are also movably arranged on the machine frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The automatic feeding mechanism applied to an orthosis of the present invention ensures that the plate will not slide laterally during the conveying process through the formed conveying space. At the same time, by the cooperation of the adsorbing member and the supporting plate, it is ensured that the plate can stably form a certain height difference with the machine frame, thereby providing guarantee for the smoothness and stability when the plate is transferred along the length direction of the machine frame to the required position. The whole process realizes automatic operation, effectively avoids the phenomenon of bumping, abrasion or even damage of the plate during transportation, realizes fast and accurate feeding of the plate, greatly improves the production efficiency, and reduces the need for manual intervention.

[0024] (2) The adsorbing member realizes the position adjustment in the height direction through the adjusting rod, so as to cope with the adsorption of plates of different masses, ensure that the adsorbing member and the supporting plate can stably fit and support the plate in a flush posture, and effectively prevent any possible sliding or offset of the plate during the conveying process, enhancing the safety and operation stability of the system.

[0025] (3) By adjusting the position of the adjusting column relative to the machine frame, the plurality of supporting feet can contact the ground simultaneously, ensuring that the machine frame always maintains a horizontal posture, effectively enhancing the stability and safety of the whole feeding mechanism, reducing vibration or shaking caused by imbalance, and being applicable to different working environments.

[0032] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0034] As Figures 1 to 3 shown, an automatic feeding mechanism for an orthosis frame according to the present invention includes: a frame 1 having a length (L) and a width (W), with anti - detachment frames 10 arranged on both sides in the length direction of the frame 1. A conveying space 100 for placing the plate is formed jointly between the anti - detachment frame 10 and the frame 1; a lifting assembly 2 movably arranged inside the frame 1, with a plurality of support plates 20 arranged in an array and equidistantly distributed on the lifting assembly 2, and at least one adsorbing part 21 is arranged between adjacent two support plates 20. The adsorbing part 21 is used to adsorb the plate and restrict it on the support plate 20; a conveying assembly 3 movably arranged inside the frame 1, and the output end of the conveying assembly 3 is connected to the lifting assembly 2 to drive the lifting assembly 2 to move along the length direction of the frame 1; when the lifting assembly 2 contracts into the frame 1, the plate can be placed on the frame 1 and at the bottom of the conveying space 100; when the lifting assembly 2 vertically lifts along the direction of the conveying space 100, there is a height difference between the plate and the frame 1, so that the conveying assembly 3 can convey the plate along the length direction of the frame 1 to the required position.

[0035] This embodiment mainly pushes the plate from one end (such as Figure 1 the right end) of the frame 1 to the other end (such as Figure 1At the left end), before that, the lifting assembly 2 contracts into the frame 1, that is, the lifting assembly 2 is completely located below the conveying space 100. As the external manipulator places the required sheet material at the right end position of the frame 1 as shown in Figure 1 The sheet material is supported by the frame 1 at this time. When the sheet material needs to be transferred, the lifting assembly 2 starts to work and gradually extends vertically into the conveying space 100. After lifting to a certain height, several suction attachments 21 can adsorb the bottom wall of the sheet material. At the same time, the top end of the support plate 20 is also in close contact with the bottom wall of the sheet material. With the complementary cooperation of the two, the sliding or detachment of the sheet material during the conveying process is effectively avoided, and the operation safety is improved. Once the sheet material is lifted to be completely within the conveying space 100 (that is, the state where the sheet material has no contact with the frame 1 and the anti - detachment frame 10, resulting in a height difference between the sheet material and the frame 1), the conveying assembly 3 can drive the lifting assembly 2 to move along the length direction of the frame 1, so as to realize the precise conveying of the sheet material from one position to another required position. It can be seen that this feeding mechanism has a high degree of automation, can realize fast and accurate sheet material feeding, greatly improves the production efficiency, reduces the need for manual intervention, and at the same time uses the height difference formed by the conveying space 100 between the sheet material and the frame 1 to provide sufficient space, effectively avoiding the collision phenomenon of the sheet material during the conveying process. At the same time, with the combined use of the support plate 20 and the suction attachments 21, the accidental sliding or deviation of the sheet material during the conveying process is prevented, enhancing the operation safety and the system reliability.

[0036] The lifting assembly 2 further includes a moving plate 22 and a lifting unit 23. The moving plate 22 is arranged at the output end of the conveying assembly 3; the lifting unit 23 is arranged on the moving plate 22, and a lifting bracket 230 is connected to the driving end of the lifting unit 23. Several support plates 20 and suction attachments 21 are both installed on the lifting bracket 230.

[0037] As Figure 2As shown, as the operator or the automated device (manipulator) places the sheet on the rack 1 at the bottom of the conveying space 100, the lifting unit 23 starts to operate. During the process of pushing the lifting bracket 230 upward in the vertical direction, the suction attachment 21 (such as an electromagnet or a vacuum chuck) starts to work. By setting the suction attachment 21 flush with the support plate 20 and combining with the precise control of the lifting unit 23, it ensures that the sheet can be accurately attached to the support plate 20, reduces the positioning error, and improves the accuracy of feeding. As the sheet is stably adsorbed and hovers above the rack 1 (i.e., near the middle section of the conveying space 100), the conveying assembly 3 can drive the lifting unit 23 to move along the length direction of the rack 1 through the moving plate 22. After reaching the target position, the lifting unit 23 descends and retracts into the rack 1 to place the shifted sheet to prepare for the next round of processing operations. It should be noted that the lifting unit 23 in this embodiment allows flexible adjustment of the lifting height and the adsorption points according to different sheet sizes and shapes, has strong adaptability, and can meet diverse production requirements.

[0038] The lifting unit 23 includes a driving motor 232 and a lifter 233 both arranged on the moving plate 22. The driving motor 232 is connected to the lifter 233 through a transmission shaft 234. And a lifting rod 235 is movably arranged vertically within the lifter 233, and the top end of the lifting rod 235 is connected to the lifting bracket 230.

[0039] Further, as Figure 2 shown, the power of the driving motor 232 is transmitted to the lifter 233 through the transmission shaft 234, causing the mechanical structure inside the lifter 233 to start operating, prompting the lifting rod 235 to move upward in the vertical direction. Along with the rising of the lifting rod 235, the lifting bracket 230 connected to its top end also rises accordingly, and then the support plate 20 and the suction attachment 21 on the lifting bracket 230 gradually approach and finally contact the surface of the sheet. Once the lifting bracket 230 rises in place, the sheet at this time is firmly adsorbed on the support plate 20, preparing for the subsequent precise conveying. In this embodiment, the lifter 233 is used as the actuator, which has higher reliability and stability compared to a simple pneumatic or hydraulic system, reducing the failure rate caused by external factors. At the same time, the precise cooperation between the driving motor 232 and the lifter 233 can achieve fine adjustment control of the sheet height, ensuring that each lift can reach the expected height and improving the accuracy of feeding. It should be noted that the working principles of the lifter 233 and the lifting rod 235 in this embodiment are the same as those of a ball screw that converts rotational motion into linear motion, and will not be elaborated here in detail.

[0040] A number of L-shaped extension plates 231 are equidistantly distributed in the length direction of the lifting bracket 230, and a suction attachment 21 is detachably arranged vertically on each L-shaped extension plate 231, so that the adsorption end of the suction attachment 21 is set flush with the support plate 20.

[0041] Preferably, as Figure 2 shown, a plurality of support plates 20 are equidistantly distributed on the upper end surface of the lifting bracket 230, ensuring that the support plates 20 stably support the plate in a horizontal posture. An L-shaped extension plate 231 is provided between every two adjacent support plates 20. This offset design enables the adsorption force and the support force to evenly cover the bottom wall of the plate, effectively avoiding the phenomenon that the plate tilts or even shakes and detaches during the conveying process. The adsorption end of the adsorbing member 21 (i.e., Figure 2 the adsorption end of the suction cup in) is flush with the support plate 20, ensuring that the plate can be accurately attached to the support plate 20, reducing the error caused by position deviation, and improving the accuracy of feeding. The detachable design of the adsorbing member 21 facilitates quick replacement or maintenance, reduces the maintenance cost of the equipment, and can flexibly adjust the type or position of the adsorbing member 21 according to different types of plates, with stronger adaptability.

[0042] An adjusting rod 24 is movably passed through the L-shaped extension plate 231 on each adsorbing member 21, and a locking nut 240 is detachably connected to the adjusting rod 24. The locking nut 240 is used to limit the movement of the adjusting rod 24 relative to the L-shaped extension plate 231.

[0043] Further preferably, in this embodiment, a threaded section may be provided at the end of the adjusting rod 24 passing through the L-shaped extension plate 231. When facing plates of different thicknesses and shapes, by moving the adjusting rod 24 within the L-shaped extension plate 231, the adsorbing member 21 can be flexibly adjusted in the vertical direction to adapt to different adsorption requirements, enhancing the versatility and flexibility of the structure. After the adjusting rod 24 is adjusted to the required position, the locking nut 240 can, through the thread fit with the above-mentioned threaded section, ensure that the adjusting rod 24 will not accidentally move during the working process, guaranteeing the safety and stability of the equipment operation, reducing the risk caused by component loosening. This structure is relatively simple, the operation is convenient and fast, saving the time required for operation, and significantly improving the overall production efficiency.

[0044] The conveying assembly 3 includes a driving member 30 and a guide rail 31 both provided on the frame 1. The output end of the driving member 30 is connected to the moving plate 22. The guide rail 31 is arranged along the length direction of the frame 1. A guide block 32 is provided at the bottom end of the moving plate 22, and the guide block 32 is movably clamped to the guide rail 31.

[0045] Further, as Figure 2As shown, when the sheet material is lifted to the required position by the lifting bracket 230 (i.e., when it is within the conveying space 100), with the operation of the driving member 30, the moving plate 22 can perform precise displacement along the guide rail 31. During this process, the guide rail 31 ensures that the moving plate 22 can only move along the length direction of the frame 1, and the tight fit between the guide block 32 and the guide rail 31 ensures the stability and straightness of the moving plate 22, preventing any unnecessary deviation. Thus, by combining the driving member 30 with the guide rail 31, the overall structural layout is simplified, the complexity is reduced, and it is convenient for installation and maintenance.

[0046] Preferably, the driving member 30 in this embodiment can adopt a linear guide rail commonly used in machinery or utilize a ball screw structure to realize the reciprocating movement of the moving plate 22 within the frame 1, without manual intervention throughout the process, effectively ensuring the smoothness and accuracy of the sheet material transportation.

[0047] A fixing plate 300 is provided on the driving member 30, a locking block 301 is provided on the fixing plate 300, and a locking hole 220 is formed on the moving plate 22, and the locking block 301 is movably inserted into the locking hole 220.

[0048] Further preferably, when the lifting bracket 230 is close to Figure 1 the right end position, at this time, the locking block 301 on the fixing plate 300 is inserted into the locking hole 220, ensuring that the moving plate 22 can be firmly locked at the key position, avoiding any possible slight deviation, and improving the accuracy of the sheet material positioning. The existence of the locking mechanism not only ensures the safety of the equipment operation but also reduces the risk caused by component loosening or failure, protecting the safety of the operator.

[0049] Further preferably, as Figure 1 shown, an inverted L-shaped limiting portion 101 is formed at the top of the anti-drop frame 10 in this embodiment. The design of the L-shaped limiting portion 101 effectively prevents the sheet material from slipping or deviating due to excessive lifting during the lifting process, ensuring the safety of the operator and reducing the risk of equipment damage.

[0050] A plurality of adjusting columns 11 are movably provided on the frame 1, and a support foot 110 is connected to the bottom end of each adjusting column 11. A plurality of support feet 110 can contact the ground when the adjusting columns 11 move relative to the frame 1, so that the frame 1 maintains a horizontal posture.

[0051] Further preferably, as Figure 1As shown, whether in a factory workshop or other working environments, the ground conditions often vary. By adjusting the position of the adjusting column 11 relative to the frame 1, the support feet 110 at each position can contact the ground, ensuring that the levelness of the entire device meets the usage requirements. For this reason, this design can adapt to various ground conditions (such as slightly uneven ground), expanding the application range of the device. It should be noted that in this embodiment, the adjusting column 11 and the frame 1 can achieve the position adjustment of the support feet 110 through threaded cooperation.

[0052] Preferably, in this embodiment, a number of rolling wheels (not shown in the figure) can also be movably arranged on the frame 1. The design of the rolling wheels significantly improves the overall mobility of the device, enabling large and heavy equipment to be relatively easily adjusted in position. This is particularly important for enterprises that frequently need to rearrange production lines, as it can greatly shorten the downtime and enhance flexibility.
