Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a positioning mechanism and a track conveying device. Background Art

[0002] Track conveyor lines are common equipment in workshops, and their main function is to transport materials. Track conveyor lines can be set up with multiple workstations, and each workstation is equipped with a positioning mechanism. The positioning mechanism is used to block the workpiece on the conveyor belt. The workpiece is assembled or processed after it stops moving at the preset workstation. There are two types of positioning mechanisms, one is a linear positioning mechanism, and the other is a rotary positioning mechanism. The rotary positioning mechanism uses a motor as a power source. The motor drives the baffle to rotate so that the baffle is close to or away from the conveyor belt, thereby blocking or releasing the workpiece. In the rotary positioning mechanism, the baffle has a large rotation amplitude, which is easy to scratch the automated assembly mechanism or scratch the operator, posing a safety hazard. Therefore, in some workshops with special needs, a linear positioning mechanism is usually used to block the workpiece. The linear positioning mechanism uses a cylinder as a power source. The cylinder drives the baffle to approach or move away from the conveyor belt in a straight line direction, thereby blocking or releasing the workpiece.

[0003] However, in the existing linear positioning mechanism, the baffle is easily affected by external forces, such as the automated assembly mechanism, the operator, or the workpiece on the conveyor line pushing against the baffle. After a period of use, the baffle is prone to loosen and deviate from the preset positioning position, causing the workpiece to be unable to accurately stay in the preset positioning position.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] like Figures 1 to 4As shown, this embodiment provides a positioning mechanism, which is used to block the workpiece on the track frame. The positioning mechanism includes a guide component 1 and a drive component 2. The guide component 1 is provided with a guide channel, and the guide channel is inclined toward the conveying route on the track frame; the drive component 2 includes a driving member 21, a blocking member 22 and a transmission member 23, one end of the transmission member 23 is rotatably connected to the output end of the driving member 21, and the other end of the transmission member 23 is rotatably connected to the blocking member 22. The blocking member 22 is slidably arranged in the guide channel, and the driving member 21 is used to drive the blocking member 22 to approach or move away from the conveying route along the extension direction of the guide channel.

[0035] Specifically, when it is necessary to block the workpiece, the driving member 21 drives the transmission member 23 to approach the conveying route, and the transmission member 23 drives the blocking member 22 to extend into the conveying route, thereby blocking the workpiece from continuing to move. When it is necessary to release the workpiece, the driving member 21 drives the transmission member 23 away from the conveying route, and the transmission member 23 drives the blocking member 22 away from the conveying route, and the workpiece continues to move on the conveying route. In this embodiment, the guide assembly 1 supports, guides and isolates and protects the blocking member 22; when one end of the blocking member 22 extends out of the guide channel and is subjected to external force, since one end of the blocking member 22 is still located in the guide channel, the inner wall of the guide channel supports the blocking member 22; the blocking member 22 is arranged in the guide channel, and the sliding of the blocking member 22 is guided to ensure that the blocking member 22 accurately blocks the workpiece at the preset positioning position; when the blocking member 22 retracts into the guide channel, the guide assembly 1 isolates and protects the blocking member 22; in this embodiment, the guide channel is tilted toward the conveying route on the track frame, so that workpieces of various heights can be blocked and the application range is wide; the transmission member 23 is used to transmit power, so that the power direction output by the driving member 21 can be changed.

[0036] The power component is used to drive the baffle to move horizontally to the top of the conveyor line to block the workpiece. This type of situation has a small scope of application. For example, when a workpiece with a lower height flows through one side of the power component, the baffle may not touch the workpiece, that is, the workpiece flows through the bottom of the baffle. If the height of the baffle is lowered, when a workpiece with a higher height flows through one side of the power component, the center of gravity of the workpiece increases, and the baffle abuts against the bottom of the workpiece, which can easily cause the workpiece to tip over.

[0037] The above problems can be solved by tilting the guide channel toward the conveying route. For example, in this embodiment, the guide channel is tilted downward, and the driving member 21 drives the transmission member 23 toward the conveying route, so that the horizontal height of the first limiting portion 221 is reduced, and the height distance between the first limiting portion 221 and the conveying route is reduced, thereby blocking workpieces with lower heights. In other embodiments, the guide channel is tilted upward, and the driving member 21 drives the transmission member 23 away from the conveying route, so that the horizontal height of the first limiting portion 221 is reduced, and the height distance between the first limiting portion 221 and the conveying route is reduced, thereby blocking workpieces with lower heights.

[0038] Optionally, the guide assembly 1 includes a guide seat 11 and a first mounting seat 12, the guide seat 11 and the first mounting seat 12 are detachably connected, the guide seat 11 and the first mounting seat 12 form a guide channel, the blocking member 22 is provided with a first limiting portion 221 at the end close to the conveying route, and the blocking member 22 is provided with a second limiting portion 222 at the end away from the conveying route, the first limiting portion 221 and the second limiting portion 222 are both located outside the guide channel, the first limiting portion 221 is used to limit the distance that the blocking member 22 slides in a direction away from the conveying route, and the second limiting portion 222 is used to limit the distance that the blocking member 22 slides in a direction close to the conveying route.

[0039] Specifically, a guide groove 111 is provided on the side of the guide seat 11 facing the first mounting seat 12. The first mounting seat 12 is detachably mounted on the side of the guide seat 11 having the guide groove 111 by means of threaded fasteners. The first mounting seat 12 encloses the guide groove 111 into a guide channel. Due to the limiting effect of the first limiting portion 221 and the second limiting portion 222, when the first mounting seat 12 is locked on the guide seat 11, the blocking member 22 cannot be completely separated from the guide channel. After the first mounting seat 12 is unlocked, the blocking member 22 can be removed from the guide groove 111.

[0040] In some embodiments, the cross-sectional areas of the first limiting portion 221 and the second limiting portion 222 are both larger than the cross-sectional area of ​​the guide channel, so that the first limiting portion 221 and the second limiting portion 222 cannot pass through the guide channel.

[0041] In this embodiment, the horizontal height of the first limiting portion 221 is lower than the horizontal height of the second limiting portion 222 , and the guide channel is arranged to be inclined downward.

[0042] Optionally, the first limiting portion 221 extends vertically downward, and a first avoidance opening 112 is provided at the bottom of the guide channel at one end close to the conveying route, and the first limiting portion 221 can be accommodated in the first avoidance opening 112. When the blocking member 22 is retracted into the guide channel, the first limiting portion 221 is accommodated in the first avoidance opening 112, reducing the exposed volume of the first limiting portion 221.

[0043] Optionally, the second limiting portion 222 extends vertically upward, and a second avoidance opening 113 is provided at the top of the end of the guide channel away from the conveying route, and the second limiting portion 222 can be accommodated in the second avoidance opening 113. When the blocking frame extends out of the guide channel, the second limiting portion 222 is accommodated in the second avoidance opening 113, reducing the exposed volume of the second limiting portion 222.

[0044] Optionally, the guide assembly 1 further includes a second mounting seat 13 , which is detachably mounted on the guide seat 11 , and a fixed end of the driving member 21 is detachably mounted on the second mounting seat 13 .

[0045] In this embodiment, the driving member 21 is horizontally arranged and the axis direction of the driving member 21 is perpendicular to the conveying route.

The first locking member is not shown in the drawings, and the first locking member is used to lock the first connecting member 24 to the first through hole to prevent the first connecting member 24 from being separated from the output end of the driving member 21 or the transmission member 23.

[0049] Optionally, the blocking member 22 is further provided with a fourth through hole 223, the fourth through hole 223 is communicated with the second through hole, and the fourth through hole 223 is provided with a second locking member, and the second locking member is used to lock the second connecting member 25 to the second through hole.
