Description

Technical Field

[0001] This utility model belongs to the technical field of automated feeding equipment for shaft workpieces, and specifically relates to an automatic feeding structure for an automatic inspection machine. Background Technology

[0002] In the field of automated production and quality control, automatic inspection machines are increasingly widely used. These machines can significantly improve production efficiency and product quality by reducing error rates through less human intervention. However, ensuring the smooth and accurate transport of workpieces from storage to inspection positions is a key challenge in achieving efficient and precise workpiece handling. Traditional feeding methods often rely on manual operation or simple mechanical devices, which not only limits the speed of the production line but also increases the likelihood of errors.

[0003] Specifically, traditional feeding structures typically include a hopper and a feeding mechanism. This feeding mechanism can only transport a single workpiece in a complete feeding cycle; that is, the feeding mechanism first receives a workpiece from the hopper, then pushes it completely out of the hopper and resets it before starting the next feeding cycle. This feeding method is slow, inefficient, and cannot meet the needs of subsequent workpiece inspection or production processes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic feeding structure for an automatic inspection machine, in view of the current state of the prior art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic feeding structure for an automatic inspection machine is proposed, including: a hopper, including a receiving cavity and a discharge port communicating with the receiving cavity, wherein the bottom wall of the receiving cavity is inclined for the workpiece stored in the receiving cavity to move towards the discharge port;

[0006] Multiple receiving blocks are spaced apart along the height direction of the silo;

[0007] Multiple pusher blocks are provided, with one pusher block movably disposed between every two adjacent receiving blocks. The multiple pusher blocks are movably disposed on one side of the discharge port, and the multiple pusher blocks move synchronously along the moving direction of the pusher blocks. The multiple receiving blocks are arranged in a stepped manner.

[0008] Each of the aforementioned pusher blocks has a receiving position and a feeding position; wherein...

[0009] When the pusher block is in the receiving position, the pusher block is used to receive the workpiece on the receiving block near the discharge port.

[0010] When the pusher block is in the feeding position, the pusher block is used to push the workpiece on it to the receiving block away from the discharge port.

[0011] In the aforementioned automatic feeding structure for an automatic inspection machine, each receiving block has a first inclined surface at its end, and each pushing block has a second inclined surface at its end; wherein,

[0012] When the pusher block is in the receiving position, the second inclined surface is used to receive the workpiece from the first inclined surface on the receiving block near the discharge port.

[0013] When the pusher block is in the feeding position, the second inclined surface is used to push the workpiece to the first inclined surface of the receiving block on the side away from the discharge port;

[0014] When the pusher block moves from the receiving position to the feeding position, a first material storage groove is formed between the first inclined surface and the side wall of the pusher block away from the discharge port, and a second material storage groove is formed between the second inclined surface and the side wall of the receiving block away from the discharge port. Both the first and second material storage grooves are used to provide a limit for the workpiece located therein.

[0015] In the above-mentioned automatic feeding structure for an automatic inspection machine, a pusher bar is movably disposed on the bottom wall of the receiving cavity. The pusher bar is disposed along the moving direction of the workpiece in the receiving cavity and is located below the workpiece.

[0016] In the above-mentioned automatic feeding structure for an automatic inspection machine, a first support is provided on the outside of the hopper, a first driving member is provided on the first support, a push block is provided at the output end of the first driving member, one end of the push block extends into the receiving cavity and moves against the push bar, for driving the push bar to move in the receiving cavity.

[0017] In the above-mentioned automatic feeding structure for an automatic inspection machine, the pusher bar is made of elastic material, with one end fixed to the bottom wall of the receiving cavity and the other end moving against the pusher block.

[0018] In the above-mentioned automatic feeding structure for an automatic inspection machine, a second support is provided on the hopper, a second driving component is provided on the second support, a connecting frame is provided at the output end of the second driving component, and multiple push blocks are connected to the connecting frame to drive the multiple push blocks to move synchronously.

[0019] In the above-mentioned automatic feeding structure for an automatic inspection machine, the width of the pusher block and the receiving block is greater than the diameter of a single workpiece but less than the diameter of two workpieces, so that each pusher block can push one workpiece at a time.

[0020] In the above-described automatic feeding structure for an automatic inspection machine, the hopper includes:

[0021] The front and rear baffles are positioned opposite each other;

[0022] A bottom plate disposed between the same ends of the front baffle and the rear baffle and forming the bottom wall;

[0023] A side baffle is connected between the front baffle and the rear baffle and forms an angle with the bottom plate. A gap is provided between the side baffle and the bottom plate, and the gap constitutes the discharge port.

[0024] In the above-mentioned automatic feeding structure for an automatic inspection machine, an adjusting plate is movably arranged between the front baffle and the rear baffle, and the adjusting plate is used to adjust the width of the receiving cavity along the direction from the front baffle to the rear baffle.

[0025] In the above-mentioned automatic feeding structure for an automatic inspection machine, a guide sleeve and a locking ring are provided on the rear baffle, and a guide post and a limiting post are fixed on the adjusting plate; the guide post is movably inserted into the guide sleeve to provide guidance for the movement of the adjusting plate; the locking ring is detachably connected to the limiting post to limit and fix the adjusting plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) By setting multiple push blocks and multiple receiving blocks, and arranging the receiving blocks in a stepped manner, the workpiece can be transported in a stepped manner by utilizing the reset stroke of the push blocks, thereby improving the transport speed and cycle time of the workpiece.

[0028] (2) By setting matching inclined structures at the ends of the receiving block and the pushing block, it is not only conducive to the smooth transition and smooth conveying of materials, but also to forming a temporary material storage trough during the movement of the pushing block, limiting the materials that have not yet been pushed, preventing the materials from slipping or being misaligned, thereby further improving the feeding accuracy and the reliability of the system operation.

[0029] (3) The design of the pusher bar helps to break the friction between materials. Especially when there is a lot of material accumulation or poor flowability, it can effectively prevent the occurrence of material jamming and ensure that the material flows continuously to the discharge port, thereby improving the overall feeding efficiency and stability.

Detailed Implementation

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0039] like Figures 1 to 6 As shown, an automatic feeding structure for an automatic testing machine according to this utility model includes: a hopper 1, multiple receiving blocks 3, and multiple pushing blocks 4.

[0040] Specifically, the hopper 1 includes a receiving cavity and a discharge port 2 communicating with the receiving cavity. The bottom wall of the receiving cavity is inclined to allow the workpieces stored in the receiving cavity to move towards the discharge port 2. Multiple receiving blocks 3 are spaced apart along the height direction of the hopper 1. Multiple pushing blocks 4 are also included, with one pushing block 4 movably disposed between every two adjacent receiving blocks 3. All pushing blocks 4 are movably disposed on one side of the discharge port 2, and move synchronously along their moving direction. The receiving blocks 3 are arranged in a stepped manner. Each pushing block 4 has a receiving position and a feeding position. When the pushing block 4 is in the receiving position, it receives the workpieces on the receiving block 3 closest to the discharge port 2. When the pushing block 4 is in the feeding position, it pushes the workpieces on it to the receiving block 3 furthest from the discharge port 2.

[0041] The number of pusher blocks 4 and receiving blocks 3 can be determined according to the specific production cycle. Generally speaking, the more pusher blocks 4 and receiving blocks 3 there are, the higher the workpiece feeding efficiency will be. To more clearly describe the working mode of this scheme, the following explanation uses three receiving blocks 3 and two pusher blocks 4 as an example.

[0042] Reference Figure 3 At this time, the pusher block 4 is in the receiving position, and the end of each pusher block 4 is slightly lower than the receiving block 3 on its side near the discharge port 2, so that the workpiece moves onto the pusher block 4 under its own weight. Of course, when the pusher block 4 is in the receiving position, the end of the pusher block 4 can also be flush with the end of the receiving block 3 on its side near the discharge port 2. After the pusher block 4 carries the workpiece, the pusher block 4 begins to move along... Figure 3 Moving upwards, entering Figure 4 Feed position shown.

[0043] At this point, the end of the pusher block 4 is slightly higher than the end of the receiving block 3 on the side away from the outlet 2, thus allowing the pusher block 4 to transport the workpiece onto the receiving block 3 on the side away from the outlet 2. Subsequently, the receiving block 3 resets, and the pusher block 4 also returns to its receiving position. Figure 3 The leftmost pusher block 4 receives a new workpiece again; and Figure 3 The workpiece on the receiving block 3 in the middle position is transferred to the leftmost pushing block 4 because the pushing block 4 on the side away from the discharge port 2 moves to a lower position.

[0044] When the pusher block 4 moves from the receiving position to the feeding position for the second time, the leftmost pusher block 4 pushes the workpiece on it onto the leftmost receiving block 3 and finally conveys it to the next process; at the same time, the right pusher block 4 transports a new workpiece to the receiving block 3 in the middle position, thus entering the next feeding cycle.

[0045] This solution sets up multiple pusher blocks 4 and multiple receiving blocks 3, and arranges the receiving blocks 3 in a stepped manner. By utilizing the reset stroke of the pusher blocks 4, the workpiece is transported in a stepped manner, which improves the transport speed and cycle time of the workpiece.

[0046] It is worth mentioning that the receiving block 3 near the discharge port 2 of the silo 1 can be a single unit or part of the silo 1.

[0047] Furthermore, in this solution, to ensure that the workpiece on the receiving block 3 can be smoothly transferred to the pushing block 4 on the side away from the discharge port 2, and to ensure that the workpiece on the pushing block 4 can be transferred to the receiving block 3 on the side away from the discharge port 2, each receiving block 3 is provided with a first inclined surface 5 at its end, and each pushing block 4 is provided with a second inclined surface 6 at its end. Preferably, the first inclined surface 5 and the second inclined surface 6 are arranged in parallel. When the pushing block 4 is in the receiving position, the second inclined surface 6 is used to receive the workpiece from the side closer to the discharge port 2. The workpiece is on the first inclined surface 5 of the material block 3; when the pusher block 4 is in the feeding position, the second inclined surface 6 is used to push the workpiece to the first inclined surface 5 of the receiving block 3 on the side away from the discharge port 2; when the pusher block 4 moves from the receiving position to the feeding position, a first material storage groove is formed between the first inclined surface 5 and the side wall of the pusher block 4 on the side away from the discharge port 2, and a second material storage groove is formed between the second inclined surface 6 and the side wall of the receiving block 3 on the side away from the discharge port 2. Both the first material storage groove and the second material storage groove are used to provide a limit for the workpiece located therein.

[0048] Reference Figure 3 Due to the arrangement of the first inclined surface 5 and the second inclined surface 6, the workpiece on the receiving block 3 can be smoothly transferred to the pushing block 4 on the side away from the discharge port 2 under its own gravity.

[0049] Similarly, refer to Figure 4 The workpiece on the pusher block 4 can also be smoothly transferred to the receiving block 3 on the side away from the discharge port 2 under its own gravity.

[0050] Along the pusher block 4 Figure 3 During the upward movement of the material, the first and second material storage tanks can limit the workpieces temporarily stored therein, preventing them from falling off during transportation.

[0051] In this solution, by setting inclined structures at the ends of receiving block 3 and pushing block 4, it is not only conducive to the smooth transition and transportation of materials, but also to forming a temporary material storage trough during the movement of pushing block 4, which limits the materials that have not yet been pushed, preventing materials from slipping or being misaligned, thereby further improving the feeding accuracy and the reliability of system operation.

[0052] It is worth mentioning that a pusher bar 7 is movably arranged on the bottom wall of the receiving cavity. The pusher bar 7 is arranged along the moving direction of the workpiece in the receiving cavity and is located below the workpiece.

[0053] Workpieces stacked in the receiving cavity of hopper 1 are prone to becoming unable to move toward discharge port 2 due to friction between themselves and with the cavity wall, thus interrupting the feeding process. The pusher bar 7 set on the bottom wall of the receiving cavity applies a pushing force to the workpiece, breaking its stagnant state in the receiving cavity, thereby ensuring that the workpiece can move continuously and smoothly toward discharge port 2.

[0054] In order to realize the movement of the pusher bar 7, this solution provides a first support 8 on the outside of the hopper 1, a first driving member 9 on the first support 8, and a push block 10 at the output end of the first driving member 9. One end of the push block 10 extends into the receiving cavity and moves against the pusher bar 7 to drive the pusher bar 7 to move in the receiving cavity.

[0055] The first driving component 9 is preferably a cylinder. When the cylinder is activated, the movement of the pusher block 10 enables the pusher bar 7 to move within the receiving cavity.

[0056] Preferably, the pusher bar 7 is made of elastic material, with one end fixed to the bottom wall of the receiving cavity and the other end moving against the pusher block 10.

[0057] The pusher bar 7, made of elastic material, can deform to a certain extent when pushed and apply a gentle disturbance force to the material during the reset process. This effectively prevents material damage and automatically returns to its original position after the pusher block 10 retracts, reducing energy loss and extending service life. This design ensures safe material handling and reduces maintenance costs.

[0058] Furthermore, a second support 11 is provided on the hopper 1, a second drive component 12 is provided on the second support 11, and a connecting frame 13 is provided at the output end of the second drive component 12. Multiple pusher blocks 4 are connected to the connecting frame 13 to drive the multiple pusher blocks 4 to move synchronously.

[0059] The second driving component 12 is preferably a cylinder, which drives multiple pusher blocks 4 to move synchronously, ensuring coordinated material pushing actions at each level and avoiding material misalignment or missed feeding caused by asynchronous actions. This significantly improves the accuracy and rhythm control of the feeding process. This not only improves work efficiency but also ensures the smooth progress of subsequent testing or production processes.

[0060] It is worth noting that the width of the pusher block 4 and the receiving block 3 is greater than the diameter of a single workpiece but less than the diameter of two workpieces, so that each pusher block 4 can push one workpiece at a time.

[0061] In this scheme, the widths of the pusher block 4 and the receiving block 3 are defined as the widths of the pusher block 4 and the receiving block 3 along their respective lengths. Figure 3 The width in the left-right direction is designed to ensure that only one material can be conveyed at a time, preventing multiple materials from stacking and entering the next process. This avoids the risk of false detection or equipment jamming, improving detection accuracy and system operational safety. This feature is crucial for ensuring the efficient operation of the production line, especially in applications requiring high-precision detection.

[0062] Furthermore, the hopper 1 includes: a front baffle 14 and a rear baffle 15 disposed opposite to each other; a bottom plate 16 disposed between the same end of the front baffle 14 and the rear baffle 15 and forming a bottom wall; a side baffle 17 connected between the front baffle 14 and the rear baffle 15 and forming an angle with the bottom plate 16, and a gap is provided between the side baffle 17 and the bottom plate 16, which forms a discharge port 2.

[0063] The hopper 1 has a simple and compact structure, facilitating processing, manufacturing, installation, and maintenance. The discharge port 2 formed by the inclined bottom plate 16 and side baffles 17 guides the material to slide down naturally. Combined with the overall structural design, this helps to achieve rapid and orderly discharge of materials. This design not only improves feeding efficiency but also simplifies the equipment's construction and reduces manufacturing costs.

[0064] Preferably, an adjusting plate 18 is movably disposed between the front baffle 14 and the rear baffle 15. The adjusting plate 18 is used to adjust the width of the receiving cavity in the direction from the front baffle 14 to the rear baffle 15.

[0065] The adjustable plate 18 allows the hopper 1 to accommodate materials of different sizes, enhancing the versatility and flexibility of the feeding structure, expanding its applicability, and reducing the cost of equipment replacement. This feature is particularly important for meeting diverse production needs, providing greater operational freedom.

[0066] Furthermore, the rear baffle 15 is provided with a guide sleeve 19 and a locking ring 20, and the adjusting plate 18 is fixed with a guide post 21 and a limiting post 22; the guide post 21 is movably inserted into the guide sleeve 19 to provide guidance for the movement of the adjusting plate 18; the locking ring 20 is detachably connected to the limiting post 22 to limit and fix the adjusting plate 18.

[0067] The aforementioned guiding and limiting structure ensures that the adjusting plate 18 moves smoothly and is accurately positioned during adjustment. Simultaneously, the locking ring 20 can lock the position, guaranteeing the stability and reliability of the adjusted structure and improving adjustment accuracy and ease of operation. This design not only enhances the system's flexibility but also ensures stable performance of the equipment during long-term use.
