Description

Technical Field

[0001] This utility model belongs to the field of workpiece production technology, and specifically relates to a directional conveying mechanism for workpieces. Background Technology

[0002] In workpiece production, for workpieces with specific structures, precise angular positioning is often required during transport to meet the requirements of subsequent processing, inspection, or assembly. Traditional workpiece transport devices typically use conveyor belts or robotic arms for handling, but these methods present the following problems in practical applications:

[0003] First, existing conveying mechanisms struggle to automatically adjust the angle of workpieces with specific structures. Due to the irregular shape of the workpieces, if they are not oriented, subsequent production processes require an additional step to rotate them to a specific angle, which not only increases operational difficulty but also consumes considerable time and effort. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a workpiece orientation and conveying mechanism. By setting a guide block with an inclined guide surface on the conveying component, the workpiece's own arc surface or flat rectangular structure contacts the inclined guide surface, generating rolling or sliding respectively, so that the workpiece automatically stabilizes to a preset angle under the action of gravity. Regardless of the posture in which the workpiece enters the guide block, a unified posture of contact between the flat rectangular structure and the inclined guide surface can be achieved, thereby completing automatic orientation.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a directional conveying mechanism for a workpiece, wherein the workpiece has an arc surface and a flat rectangular structure, and the conveying mechanism includes:

[0006] Conveyor belt;

[0007] A lifting assembly is disposed on the side of the conveyor belt. The lifting assembly has a support block and a lifting block. The support block is used to receive the workpiece transported by the conveyor belt, and the lifting block is used to drive the workpiece to rise to a preset position.

[0008] A transport component is disposed on the side of the lifting component and has a guide ramp with an inclined guide surface.

[0009] The workpiece is placed on the guide ramp. When the arc surface contacts the ramp guide surface, the workpiece rolls along the ramp guide surface. When the flat structure contacts the ramp guide surface, the workpiece slides along the ramp guide surface to keep the workpiece at a preset angle.

[0010] In the aforementioned workpiece orientation and conveying mechanism, the lifting assembly further includes:

[0011] Support base, the support block is connected to the support base;

[0012] A first detection element is disposed on the support base and located to the side of the support block. The first detection element is used to detect whether the workpiece is on the support block.

[0013] The first driving component is connected to the output end of the lifting block, and the first driving component is electrically connected to the first detection component, for driving the lifting block to move up and down.

[0014] In the above-mentioned orientation conveying mechanism for workpieces, a limiting part is also provided on the guide inclined block. The limiting part is integrally formed with the inclined guide surface and is located at the end of the workpiece movement path. The limiting part moves against the workpiece to provide a limiting position for the workpiece.

[0015] In the aforementioned orientation conveying mechanism for a workpiece, the conveying component further includes:

[0016] A push block is located to the side of the guide ramp, and the push block moves against the workpiece on the guide ramp to push the workpiece.

[0017] The second driving component is connected to the output end of the push block, and the second driving component is used to drive the push block to move.

[0018] In the above-mentioned orientation conveying mechanism for workpieces, a second detection element is also provided above the guide ramp. The second detection element is used to detect whether the workpiece on the guide ramp is at a preset angle.

[0019] In the aforementioned orientation conveying mechanism for a workpiece, the conveying component further includes:

[0020] A fixed base is disposed on the side of the lifting assembly, and the guide block is connected to the fixed base;

[0021] A fixing plate is fixedly mounted on the fixing base. The fixing plate has multiple support grooves arranged side by side. The fixing plate is used to provide support for the workpiece.

[0022] A transport component that reciprocates on the fixed base is used to transport the workpiece.

[0023] In the above-described orientation conveying mechanism for a workpiece, the surface of the conveying component has a plurality of V-shaped grooves arranged in parallel, the V-shaped grooves being used to provide support for the workpiece.

[0024] In the aforementioned orientation conveying mechanism for a workpiece, the conveying component further includes:

[0025] The third driving component has a driving shaft at its output end, and the third driving component is used to drive the driving shaft to rotate.

[0026] The drive shaft is equipped with a pulley assembly, which is connected to the conveying component. The drive shaft drives the conveying component to reciprocate through the pulley assembly.

[0027] In the aforementioned orientation conveying mechanism for a workpiece, the conveying component further includes:

[0028] A rotating shaft is inserted into the fixed base, and the pulley assembly is connected to the rotating shaft for transmission.

[0029] A rotating block, which is sleeved on the rotating shaft;

[0030] An eccentric shaft, one end of which is inserted into the rotating block and the other end of which is inserted into the conveying component.

[0031] In the aforementioned workpiece orientation conveying mechanism, the pulley assembly includes:

[0033] The driven wheel is sleeved on the rotating shaft;

[0034] A belt is fitted onto the driving wheel and the driven wheel, and the driving wheel drives the driven wheel to rotate via the belt.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) By setting a guide block with an inclined guide surface on the conveying component, the workpiece’s own arc surface or flat square structure comes into contact with the inclined guide surface, generating rolling or sliding respectively, so that the workpiece is automatically stabilized to a preset angle under the action of gravity; no matter what posture the workpiece enters the guide block, it can ultimately achieve a unified posture of the flat square structure contacting the inclined guide surface, thereby completing automatic orientation.

[0037] (2) The conveying mechanism in this solution integrates lifting components, detection elements and drive actuators to form a multi-level linkage control process: after the first detection component detects the workpiece in place, it triggers the lifting component to move, and the lifting block raises the workpiece to a preset height; then, the conveying component transports the workpiece to the guide ramp, where the workpiece is automatically oriented; next, the pusher moves the workpiece to the detection area of ​​the second detection component; after the second detection component confirms through visual recognition that the workpiece is at a preset angle where the flat structure contacts the inclined guide surface, the conveying component moves the workpiece to the next process; the whole process realizes closed-loop control from receiving, positioning to moving, ensuring that the workpiece is finally at a precise preset angle and position;

[0038] (3) A reciprocating conveyor with a V-groove is used, combined with an eccentric transmission system consisting of a third drive unit, a pulley assembly, a rotating shaft, a rotating block and an eccentric shaft, to achieve efficient and continuous transport of the workpiece: the V-groove provides support for the workpiece and prevents it from shifting; the eccentric transmission structure drives the conveyor to swing periodically to achieve stable pushing.

[0047] 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.

[0048] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment 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 indicator will also change accordingly.

[0049] like Figure 1 and Figure 7 As shown, this solution provides a directional conveying mechanism for a workpiece. The workpiece 1 has an arc surface 2 and a flat rectangular structure 3. The conveying mechanism includes: a conveyor belt 4; a lifting assembly 5, which is disposed on the side of the conveyor belt 4, the lifting assembly 5 having a support block 6 and a lifting block 7, the support block 6 being located below the side of the conveyor belt 4 for receiving the workpiece 1 conveyed by the conveyor belt 4, and the lifting block 7 for driving the workpiece 1 to rise to a preset position; and a conveying assembly 8, which is disposed on the side of the lifting assembly 5 and has a guide ramp 9, the guide ramp 9 having an inclined guide surface 10; the workpiece 1 is placed on the guide ramp 9, and when the arc surface 2 contacts the inclined guide surface 10, the workpiece 1 rolls along the inclined guide surface 10; when the flat rectangular structure 3 contacts the inclined guide surface 10, the workpiece 1 slides along the inclined guide surface 10, for placing the workpiece 1 at a preset angle.

[0050] During operation, workpiece 1 can be placed on conveyor belt 4 manually or automatically. Conveyor belt 4 transports workpiece 1 until it falls onto support block 6 below conveyor belt 4. At this time, lifting block 7 rises under the action of lifting component 5, lifting workpiece 1 to a preset position. Subsequently, conveying component 8 transports workpiece 1 from lifting block 7 to guide inclined block 9. At this time, depending on the initial posture of workpiece 1, the following two situations may occur: When the arc surface 2 of workpiece 1 first contacts the inclined guide surface 10, workpiece 1 can roll along the inclined guide surface 10 under the action of gravity until the flat rectangular structure 3 on it contacts the inclined guide surface 10; at this time, due to the contact area By increasing frictional resistance, workpiece 1 transitions from rolling to sliding, eventually stabilizing at a preset angle. When workpiece 1 first contacts the inclined guide surface 10 with the flat rectangular structure 3, due to the greater friction between it and the inclined guide surface 10, workpiece 1 will not roll but will slide directly along the inclined guide surface 10 to its final position. Through the combination of these two methods, regardless of the posture in which workpiece 1 enters the guide block 9, it can eventually stabilize at the preset angle where the flat rectangular structure 3 contacts the inclined guide surface 10, thus achieving automatic orientation of workpiece 1. There is no need to add an extra step to rotate workpiece 1 to a specific angle in subsequent production processes, which not only reduces the difficulty of operation but also significantly improves work efficiency.

[0051] Furthermore, the lifting assembly 5 also includes: a support base 11, with the support block 6 connected to the support base 11; a first detection element 12, which is disposed on the support base 11 and located to the side of the support block 6, the first detection element 12 being used to detect whether there is a workpiece 1 on the support block 6; and a first driving element 13, with the lifting block 7 connected to the output end of the first driving element 13, and the first driving element 13 being electrically connected to the first detection element 12, for driving the lifting block 7 to rise and fall.

[0052] During operation, when workpiece 1 falls from conveyor belt 4 into support block 6, first detection element 12 detects the presence of workpiece 1 and transmits the detection information to first drive element 13 in the form of an electrical signal. After receiving the signal, first drive element 13 starts to drive lifting block 7 to rise. Lifting block 7 contacts workpiece 1 on support block 6 and drives workpiece 1 away from support block 6 to rise to a preset height. Subsequently, transport component 8 takes away workpiece 1 at the preset height and transports it to guide inclined block 9. The first detection element 12 is preferably a photoelectric sensor, and the first drive element 13 can be a motor, hydraulic cylinder, or pneumatic cylinder.

[0053] Furthermore, a limiting part 14 is also provided on the guide block 9. The limiting part 14 is integrally formed with the inclined guide surface 10 and is located at the end of the moving path of the workpiece 1. When the workpiece 1 slides down along the inclined guide surface 10 and comes into contact with the limiting part 14, the workpiece 1 is blocked and stops moving. The inclination angle and length of the inclined guide surface 10 are reasonably designed according to the outer diameter, shape characteristics and required guiding distance of the workpiece 1 to ensure that the workpiece 1 can roll or slide smoothly to the preset angle.

[0054] Furthermore, the conveying assembly 8 also includes: a pusher 15 located on the side of the guide ramp 9, the pusher 15 moving against the workpiece 1 on the guide ramp 9 to push the workpiece 1; and a second drive member 16, the pusher 15 being connected to the output end of the second drive member 16, the second drive member 16 being used to drive the pusher 15 to move.

[0055] In order to detect whether the workpiece 1 on the guide block 9 has been stably positioned at a preset angle, a second detection element 17 is also provided above the guide block 9.

[0056] During operation, when workpiece 1 rolls or slides along inclined guide surface 10 to a preset angle and comes into contact with limiting part 14 under the action of gravity, the second driving member 16 is activated, driving push block 15 to contact workpiece 1 and push workpiece 1 along inclined guide surface 10 into the detection area of ​​second detection member 17; the direction in which push block 15 pushes workpiece 1 is opposite to the direction in which workpiece 1 moves along inclined guide surface 10 under the action of gravity; after workpiece 1 stabilizes, second detection member 17 performs visual inspection on workpiece 1 to confirm whether it is at the preset angle; second detection member 17 can be an industrial camera or other visual inspection equipment, and second driving member 16 can be a motor, hydraulic cylinder or pneumatic cylinder.

[0057] Furthermore, the conveying assembly 8 also includes: a fixed seat 18, which is disposed on the side of the lifting assembly 5, and a guide block 9 is connected to the fixed seat 18; a fixed plate 19, which is fixed on the fixed seat 18, and has a plurality of side-by-side support grooves 20, which is used to provide support for the workpiece 1; and a conveying component 21, which reciprocates on the fixed seat 18 for conveying the workpiece 1.

[0058] Furthermore, the surface of the transport component 21 has a plurality of V-shaped grooves 22 arranged in parallel, which are used to provide support for the workpiece 1; the depth and width of the V-shaped grooves 22 are matched with the geometric dimensions of the workpiece 1, providing support for the workpiece 1 and preventing it from shifting, thereby improving the stability of the workpiece 1 during transportation.

[0059] During operation, when workpiece 1 rises to a preset height under the drive of lifting block 7, conveying component 21, driven by conveying assembly 8, removes workpiece 1 from lifting block 7 and transports workpiece 1 to guide inclined block 9. When workpiece 1 is stabilized on guide inclined block 9 at a preset angle where flat structure 3 contacts inclined guide surface 10, second driving component 16 is activated, driving push block 15 to contact workpiece 1 and push workpiece 1 along inclined guide surface 10 to the detection area of ​​second detection component 17. Subsequently, second detection component 17 performs visual inspection on workpiece 1 to detect whether workpiece 1 is at a preset angle. After the inspection is completed, conveying component 21 removes workpiece 1 from guide inclined block 9 again and continues to transport workpiece 1 between various support slots 20 on fixed plate 19. When conveying component 21 transports workpiece 1, workpiece 1 is precisely accommodated in the corresponding V-shaped groove 22 on conveying component 21 to ensure positional consistency during transmission. V-shaped groove 22 can effectively prevent workpiece 1 from shifting or sliding, thereby improving overall conveying accuracy and stability.

[0060] Furthermore, the conveying component 8 also includes: a third driving member 23, the output end of which is provided with a driving shaft 24, the third driving member 23 is used to drive the driving shaft 24 to rotate; a pulley assembly is provided on the driving shaft 24, the pulley assembly is connected to the conveying component 21 for transmission, and the driving shaft 24 drives the conveying component 21 to reciprocate through the pulley assembly.

[0061] Furthermore, the conveying assembly 8 also includes: a rotating shaft, which is inserted into the fixed base 18 and the pulley assembly is connected to the rotating shaft; a rotating block 25, which is sleeved on the rotating shaft, and the rotating block 25 can rotate synchronously due to the rotation of the rotating shaft driven by the pulley assembly; and an eccentric shaft 26, one end of which is connected to the rotating block 25 and the other end of which is connected to the conveying component 21, and the rotating block 25 drives the conveying component 21 to reciprocate through the eccentric shaft 26.

[0062] The rotating shaft, rotating block 25 and eccentric shaft 26 form an eccentric transmission structure. When the rotating shaft rotates around its own axis, the eccentric shaft 26 rotates together with the rotating block 25 and drives the conveying component 21 to perform periodic reciprocating motion on the fixed seat 18 under its eccentric action, so as to achieve efficient and accurate material transfer.

[0063] During operation, the third drive unit 23 is activated, driving the drive shaft 24 to rotate. The drive shaft 24 transmits power to the rotating shaft through the pulley assembly, causing the rotating shaft to rotate synchronously. The rotating block 25 is sleeved on the rotating shaft and rotates synchronously with the rotating shaft, thereby driving the eccentric shaft 26 to rotate around the axis of the rotating shaft. The eccentric structure of the eccentric shaft 26 causes the conveying component 21 to reciprocate on the fixed seat 18. When the eccentric shaft 26 rotates with the rotating block 25 to a specific angle, it pushes the conveying component 21 to swing forward, thereby conveying the workpiece 1. When the eccentric shaft 26 continues to rotate and completes half a cycle of motion to return to the initial position, the conveying component 21 also resets, ready for the next pushing operation. The third drive unit 23 is preferably a rotary motor.

[0064] Furthermore, the pulley assembly includes: a driving pulley 27, which is sleeved on the drive shaft 24; a driven pulley 28, which is sleeved on the rotating shaft; and a belt 29, which is sleeved on the driving pulley 27 and the driven pulley 28, wherein the driving pulley 27 drives the driven pulley 28 to rotate via the belt 29.

[0065] During operation, since the driving wheel 27 is mounted on the drive shaft 24, when the third driving component 23 drives the drive shaft 24 to rotate, the driving wheel 27 rotates synchronously and transmits power to the driven wheel 28 through the belt 29, causing the driven wheel 28 to rotate synchronously. Since the driven wheel 28 is mounted on the rotating shaft, the rotation of the driven wheel 28 drives the rotating shaft to rotate around its own axis, thereby achieving effective power transmission.
