Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, and in particular to a blocking and releasing device. Background Technology

[0002] In the field of industrial production automation, the transmission and positioning control of workpieces is a key link in ensuring production efficiency and product quality. Among them, blocking devices, as a commonly used automated execution component, are widely used in assembly lines and other scenarios to accurately block, position, or temporarily stop workpieces during transmission, so as to facilitate the smooth progress of subsequent processes (such as inspection, assembly, sorting, etc.).

[0003] In existing technologies, blocking devices extend blocking components via a drive mechanism, bringing the plane of the blocking component into direct contact with the plane of the workpiece during transport. Static friction between the two components effectively blocks the workpiece. However, this traditional surface-to-surface contact blocking method has significant technical drawbacks: due to the workpiece's inertia during transport and the relatively large static friction generated in surface contact, when the drive mechanism receives a release command requiring the blocking component to retract, this significant static friction strongly hinders the component's resetting motion. In actual production, this problem often prevents the drive mechanism from overcoming the friction to retract smoothly, leading to machine alarms and shutdowns. Frequent machine shutdowns not only severely impact the continuous operation of the production line, reducing production efficiency and increasing equipment maintenance costs, but can also cause unnecessary damage to the workpiece or equipment due to sudden shutdowns, resulting in economic losses for the company.

[0004] Therefore, there is an urgent need to propose a blocking and release device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a blocking and releasing device that reduces the friction between the blocking component and the blocked component, ensuring that the blocking and releasing device can easily and quickly respond to machine commands to complete the retraction action, and ensuring the continuous and stable operation of the production line.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A blocking and releasing device includes a frame, a fixture, a conveying mechanism, and a blocking mechanism. The fixture is provided with a stop block, and the frame is provided with the conveying mechanism for transporting the fixture. The blocking mechanism includes a driving member, a mounting member, and a blocking member. The blocking member is rotatably mounted on the mounting member, and its rotation axis is parallel to the front end face of the stop block. All points on the rotation circumference of the blocking member are equidistant from its rotation axis. The output end of the driving member is connected to the mounting member for driving the mounting member to reciprocate in a direction perpendicular to the transport path of the fixture. The mounting member has a blocking position that blocks the movement of the fixture and a releasing position that allows the fixture to move. When the mounting member is in the blocking position, the rotation circumference of the blocking member abuts against the front end face of the stop block.

[0008] In some alternative embodiments, the blocking element is a cam bearing follower.

[0009] In some optional embodiments, the blocking mechanism further includes a base and a guide member, the base being fixedly connected to the frame, the drive member and the guide member being fixedly connected to the base, the guide member having a guide groove extending in a direction perpendicular to the jig transport path, and the mounting member slidingly engaging with the guide groove.

[0010] In some alternative embodiments, the guide member has a clearance groove at one end near the conveying mechanism for avoiding the blocking member.

[0011] In some optional embodiments, the mounting member includes a connected guide portion and a mounting portion, the guide portion being connected to the output end of the drive member and slidingly engaging with the guide groove, and the mounting portion being used to mount the blocking member, wherein the mounting portion is located below the stop block.

[0012] In some alternative embodiments, the rotating circumferential surface of the blocking member protrudes beyond the rear end face of the mounting portion.

[0013] In some alternative embodiments, the height of the mounting portion is less than the height of the guide portion.

[0014] In some alternative embodiments, the blocking and releasing device further includes a guiding mechanism comprising a sliding rail and a slider, the sliding rail being mounted on the frame and extending along the transport direction of the conveying mechanism, and the slider being fixedly connected to the fixture.

[0015] In some optional embodiments, the stop includes a blocking part and a connecting part, the connecting part protruding from the top of the blocking part, the fixture having a mounting groove adapted to the shape of the connecting part, the connecting part being embedded in the mounting groove, and the blocking part protruding from the lower surface of the fixture for abutting against the blocking member.

[0016] In some alternative embodiments, the drive element includes a cylinder.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a blocking and releasing device, including a frame, a fixture, a conveying mechanism, and a blocking mechanism. The conveying mechanism drives the fixture to move. When the driving component receives a blocking command, it drives the mounting component to approach the conveying mechanism in a direction perpendicular to the fixture's transport path, causing the blocking component to enter the moving path of the stop block. When the stop block reaches the blocking component, the blocking component abuts against the front end of the stop block, stopping the fixture from moving, so as to facilitate the processing of the workpiece loaded on the fixture. When the driving component receives a releasing command, it drives the mounting component to move away from the conveying mechanism in a direction perpendicular to the fixture's transport path, causing the blocking component to exit the moving path of the stop block, and the fixture continues to move under the drive of the conveying mechanism. The blocking component is rotatably mounted on the mounting component, with its rotation axis parallel to the front end face of the stop block. The distance from each point on the rotating circumference of the blocking component to its rotation axis is equal, so that the blocking component and the stop block form a surface / line contact during movement, and always exhibit rolling friction. This contact method significantly reduces the friction between the two, which helps to reduce the load on the drive component. This allows the blocking and release device to easily and quickly respond to machine commands to complete the retraction action, greatly reducing alarm shutdowns caused by the drive component's inability to complete the retraction action, thereby ensuring the continuous and stable operation of the production line.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figures 1-5 As shown, this embodiment provides a blocking and releasing device, including a frame 1, a fixture 2, a conveying mechanism 4, and a blocking mechanism 5. The fixture 2 is provided with a stop block 3, and the frame 1 is provided with the conveying mechanism 4 for transporting the fixture 2. The blocking mechanism 5 includes a driving member 51, a mounting member 52, and a blocking member 53. The blocking member 53 is rotatably mounted on the mounting member 52, and its rotation axis is parallel to the front end face of the stop block 3. All points on the rotational circumference of the blocking member 53 are equidistant from its rotation axis. The output end of the driving member 51 is connected to the mounting member 52 for driving the mounting member 52 to reciprocate along a direction perpendicular to the transport path of the fixture 2. The mounting member 52 has a blocking position that blocks the movement of the fixture 2 and a releasing position that allows the fixture 2 to move. When the mounting member 52 is in the blocking position, the rotational circumference of the blocking member 53 abuts against the front end face of the stop block 3. The front end face of the stop block 3 is the front end face of the stop block 3 along its own direction of movement.

[0036] In this embodiment, the conveying mechanism 4 drives the fixture 2 to move. When the driving member 51 receives a blocking command, the driving member 51 drives the mounting member 52 to approach the conveying mechanism 4 in a direction perpendicular to the transport path of the fixture 2, so that the blocking member 53 enters the moving path of the stop block 3. When the stop block 3 reaches the blocking member 53, the blocking member 53 abuts against the front end of the stop block 3, so that the fixture 2 stops moving, so as to facilitate the processing of the workpiece loaded on the fixture 2. When the driving member 51 receives a release command, the driving member 51 drives the mounting member 52 to move away from the conveying mechanism 4 in a direction perpendicular to the transport path of the fixture 2, so that the blocking member 53 exits the moving path of the stop block 3, and the fixture 2 continues to move under the drive of the conveying mechanism 4.

[0037] The blocking component 53 is rotatably mounted on the mounting component 52, with its rotation axis parallel to the front end face of the stop block 3. The distance from each point on the rotation circumference of the blocking component 53 to its rotation axis is equal, so that the blocking component 53 forms a surface / line contact with the stop block 3 during movement, and always forms rolling friction. This contact method significantly reduces the friction between the two, which helps to reduce the load on the drive component 51. This allows the blocking and release device to easily and quickly respond to the machine command to complete the retraction action, greatly reducing the alarm shutdown phenomenon caused by the drive component 51 failing to complete the retraction action, thereby ensuring the continuous and stable operation of the production line.

[0038] In some optional embodiments, the blocking element 53 is a cam bearing follower, which has the advantages of compact structure, saving installation space, and high load capacity. Moreover, as a standard part, the cam bearing follower has high size and precision level and low procurement cost. The specific structure of the cam bearing follower is prior art and will not be described in detail here.

[0039] In some optional embodiments, the blocking mechanism 5 further includes a base 54 and a guide 55. The base 54 is fixedly connected to the frame 1, and both the drive member 51 and the guide 55 are fixedly connected to the base 54. The guide 55 has a guide groove 551 extending in a direction perpendicular to the transport path of the fixture 2, and the mounting member 52 slides in the guide groove 551. The guide 55 can guide and limit the movement of the mounting member 52 in a direction perpendicular to the transport path of the fixture 2. It can not only provide the displacement accuracy of the blocking member 53, but also bear the lateral force generated by the fixture 2 on the blocking mechanism 5 under the drive of the conveying mechanism 4, so that the output end of the drive member 51 only bears the axial force, which helps to reduce the load on the drive member 51 and extend the service life of the drive member 51.

[0040] like Figure 2 As shown, in some optional embodiments, the guide member 55 has a clearance groove 552 at one end near the conveying mechanism 4 to avoid the blocking member 53. When the driving member 51 drives the mounting member 52 to retract, the clearance groove 552 can accommodate the blocking member 53, thus avoiding motion interference between the guide member 55 and the blocking member 53.

[0041] like Figure 2 and Figure 3 As shown, in some optional embodiments, the mounting member 52 includes a guide portion 521 and a mounting portion 522 connected together. The guide portion 521 is connected to the output end of the drive member 51 and slides in cooperation with the guide groove 551. The mounting portion 522 is used to mount the blocking member 53. The mounting portion 522 is located below the stop block 3, which can prevent the mounting portion 522 from contacting the fixture 2 or the stop block 3.

[0042] In some optional embodiments, the rotating circumferential surface of the blocking member 53 protrudes beyond the rear end face of the mounting portion 522, further preventing the mounting portion 522 from contacting the fixture 2 or the stop 3, and ensuring that the rotating circumferential surface of the blocking member 53 rolls in contact with the stop 3. The rear end face of the mounting portion 522 is the end face of the mounting portion 522 facing towards the stop 3.

[0043] In order to facilitate the installation of the blocking member 53, in some optional embodiments, the height of the mounting part 522 is less than the height of the guide part 521, so as to reserve space for the installation of the blocking member 53, avoid interference between the blocking member 53 and the lower frame 1, and facilitate the installation and removal of the blocking member 53.

[0044] like Figure 1 As shown, in some optional embodiments, the blocking and releasing device further includes a guiding mechanism 6, which includes a sliding rail 61 and a slider 62 that are slidably engaged. The sliding rail 61 is mounted on the frame 1 and extends along the transport direction of the conveying mechanism 4. The slider 62 is fixedly connected to the fixture 2. The guiding mechanism 6 provides guidance and limiting for the movement of the fixture 2 along the transport direction of the conveying mechanism 4, and can prevent the fixture 2 from tilting when blocked by the blocking member 53, ensuring that the fixture 2 remains unchanged in posture before and after passing through the blocking and releasing device.

[0045] like Figure 4 and Figure 5 As shown, in some optional embodiments, the stop 3 includes a blocking part 31 and a connecting part 32. The connecting part 32 protrudes from the top of the blocking part 31. The fixture 2 has a mounting groove that matches the shape of the connecting part 32, and the connecting part 32 is embedded in the mounting groove. The blocking part 31 protrudes from the lower surface of the fixture 2 and is used to abut against the blocking member 53. By embedding the connecting part 32 in the mounting groove, the connection strength between the stop 3 and the fixture 2 is enhanced, preventing the stop 3 from loosening and falling off under the force of the blocking member 53, which is beneficial to improving the safety and stability of production. By having the blocking part 31, which is used to abut against the blocking member 53, protrude from the lower surface of the fixture 2, it is possible to avoid motion interference between the stop 3 and the blocking release mechanism and the processing device above the fixture 2, which is beneficial to improving the smoothness and aesthetics of the production line layout.

[0046] In some alternative embodiments, the drive unit 51 includes a cylinder that has a fast response speed and high motion efficiency, and can quickly respond to the machine's blocking and releasing commands.

[0047] In other alternative embodiments, the drive element 51 may also be a hydraulic cylinder.

[0048] In some alternative embodiments, the conveying mechanism 4 includes, but is not limited to, belt conveyors or roller conveyors, which are not limited here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
