Description

Technical Field

[0001] The utility model relates to a workpiece conveying device in an automated production line, in particular to an anti-jamming workpiece conveying device. Background Art

[0002] At present, in order to improve the processing efficiency and automation level of workpieces, many factories are equipped with workpiece automation production lines. These workpiece automation production lines all involve the transportation of workpieces, that is, a workpiece conveying device is used to automatically convey multiple workpieces to various processing stations in an orderly, precise and continuous manner for processing in various processes. The structure of the workpiece conveying device usually includes a workbench, and a workpiece input mechanism and a workpiece output mechanism installed on the workbench. The workpiece input mechanism and the workpiece output mechanism are connected to each other, so that multiple workpieces can be directly conveyed to the workpiece output mechanism in sequence through the workpiece input mechanism. However, in actual production, it is found that when the multiple workpieces continuously conveyed by the workpiece input mechanism cannot be conveyed in time as the multiple workpieces approach the input end of the workpiece output mechanism, the multiple workpieces often become close to each other and densely arranged together to form a pile, and then directly block between the output end of the workpiece input mechanism and the input end of the workpiece output mechanism, resulting in an accidental jam, thereby causing the workpiece conveying device to fail to work normally. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an anti-jamming workpiece conveying device which can effectively prevent multiple workpieces from being jammed when being conveyed continuously.

[0004] The technical problem of the utility model is achieved through the following technical solutions:

[0005] A workpiece conveying device for preventing jamming comprises a workbench, and a workpiece input mechanism and a workpiece output mechanism installed on the workbench, wherein a screw conveying mechanism and a transition conveying mechanism connected in sequence are provided between the workpiece input mechanism and the workpiece output mechanism; the workpiece input mechanism continuously conveys a plurality of workpieces that are closely adjacent to and densely arranged to the screw conveying mechanism, and the screw conveying mechanism sequentially separates the workpieces into a variable pitch arrangement, and then the workpieces are input one by one into the transition conveying mechanism, which then sequentially conveys them to the workpiece output mechanism.

[0006] The screw conveying mechanism includes a linear screw and a screw motor driving the linear screw to rotate. The input end of the linear screw is connected to the output end of the workpiece input mechanism, and the output end of the linear screw is connected to the input end of the transition conveying mechanism.

[0007] The linear screw is driven by a screw motor to rotate in one direction, thereby separating the multiple closely spaced and densely arranged workpieces into variable pitch arrangements in sequence through the screw pitch, and then inputting the workpieces into the transition conveying mechanism one by one in a straight line.

[0008] The variable pitch arrangement distance of the linear screw increases gradually from the input end to the output end.

[0009] The transition conveying mechanism is composed of a turntable and a turntable motor that drives the turntable to rotate. A plurality of circumferentially evenly distributed conveying grooves are provided on the outer circumference of the turntable, and the turntable drives the plurality of conveying grooves to connect one by one with the output end of the linear screw through rotation, and then the plurality of workpieces output from the output end are installed one by one in the conveying grooves.

[0010] The rotation axis of the turntable is perpendicular to the rotation axis of the linear screw.

[0011] The workpiece input mechanism includes an input guide rail, the input end of which extends out of the input end of the linear screw, the output end of which passes over the input end of the linear screw and extends all the way to the output end of the linear screw, and the linear input direction of the input guide rail is parallel to the rotation axis of the linear screw.

[0012] The linear screw is arranged on one side of the input guide rail, and a workpiece baffle is provided on the other side of the input guide rail relative to the linear screw.

[0013] The workpiece output mechanism comprises an output belt and a belt wheel which cooperates with the output belt to form a circular rotation. One side of the output belt is provided with a plurality of processing stations.

[0014] The output belt is provided with a plurality of positioning grooves; the turntable drives the plurality of conveying grooves to connect with the plurality of positioning grooves one by one through rotation, and then conveys the plurality of workpieces into the positioning grooves in sequence.

[0015] Compared with the prior art, the present invention mainly adds a screw conveying mechanism and a transition conveying mechanism that are connected in sequence between the workpiece input mechanism and the workpiece output mechanism of the workpiece conveying device. In this way, when the workpiece input mechanism continuously conveys multiple closely spaced and densely arranged workpieces to the input end of the screw conveying mechanism, the screw conveying mechanism can first separate the workpieces into a variable pitch arrangement, and then input them one by one into the transition conveying mechanism. Finally, the transition conveying mechanism can sequentially convey the multiple workpieces to the workpiece output mechanism. Obviously, by adding the screw conveying mechanism and the transition conveying mechanism that are connected in sequence, the phenomenon of multiple workpieces getting stuck during continuous conveyance can be effectively avoided, ensuring the smooth operation of the automated production line.

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] A workpiece conveying device to prevent jamming, such as Figures 1 to 3 As shown, it relates to a workpiece conveying device for preventing workpieces from being stuck in an automated production line, which is mainly suitable for preventing cylindrical workpieces from being stuck. Figure 6 As shown, a cylindrical battery cell 22 with a mold support 21 is selected as the workpiece 2 to be conveyed. The mold support is also cylindrical in shape. Since the actual production relies on the cylindrical mold support to achieve continuous and smooth transportation, square batteries can also be used on the mold support 21. Even other workpieces with a cylindrical shape can be suitable for the workpiece conveying device.

[0025] The workpiece conveying device comprises a workbench 1 on which a workpiece input mechanism 3, a screw conveying mechanism 4, a transition conveying mechanism 5 and a workpiece output mechanism 6 are sequentially connected and installed.

[0026] The workbench 1 is a box-type frame structure installed on the ground, mainly serving as an installation base for other components.

[0027] The workpiece input mechanism 3 includes a linear input input guide rail 31, which can continuously transport multiple workpieces 2 that are close to each other and densely arranged to the screw conveying mechanism 4. For example, in this embodiment, multiple cylindrical battery cells 22 with mold supports 21 are transported in a linear manner by placing the mold supports on the input guide rail 31; of course, in actual design, other similar structures such as circulating conveyor belts can also be used as workpiece input mechanisms.

[0028] The screw conveying mechanism 4 includes a linear screw 41 and a screw motor 42 that drives the linear screw to rotate unidirectionally. The input end of the linear screw 41 is connected to the output end of the workpiece input mechanism 3, usually the input end of the input guide rail 31 extends out of the input end of the linear screw 41, and the output end of the input guide rail 31 passes over the input end of the linear screw 41 and extends to the output end of the linear screw, and the linear input direction of the input guide rail 31 is parallel to the rotation axis of the linear screw 41, and the output end of the linear screw is connected to the input end of the transition conveying mechanism 5. Therefore, the screw conveying mechanism 4 can separate the multiple workpieces 2 that are closely connected and densely arranged and continuously conveyed by the workpiece input mechanism 3 into a variable pitch arrangement through the pitch, and then input them into the transition conveying mechanism 5 one by one in a straight line.

[0029] At the same time, the output end of the input guide rail 31 passes over the input end of the linear screw 41 and extends to the output end of the linear screw. The purpose is to assist the linear screw 41 to smoothly drive the workpieces 2 arranged in sequence with variable pitches for transportation, and the variable pitch arrangement distance of the linear screw 41 from the input end to the output end gradually increases, that is, the pitch gradually increases. This is also to ensure the sequential transportation of the workpieces 2 and smoother connection between the linear screw 41 and the front and rear mechanisms.

[0030] In addition, the linear screw 41 is usually arranged on one side of the input guide rail 31, and a workpiece baffle 32 is provided on the other side of the input guide rail relative to the linear screw to prevent the workpiece 2 from escaping from the input guide rail 31 and the linear screw 41 during transportation.

[0031] The transition conveying mechanism 5 is composed of a circular turntable 51 and a turntable motor 52 for driving the turntable to rotate. A plurality of circumferentially evenly distributed conveying grooves 511 are provided on the outer circumference of the turntable 51. The turntable 51 can drive the plurality of conveying grooves 511 to connect one by one with the output end of the linear screw 41 by rotating, and then the plurality of workpieces 2 output from the output end are installed one by one in the conveying grooves 511. The rotation axis of the turntable 51 is exactly perpendicular to the rotation axis of the linear screw 41.

[0032] The workpiece output mechanism 6 includes an output belt 61 and a belt pulley 62 that cooperates with the output belt to form a circular rotation. The output belt 61 is provided with Figure 5 Thus, when the turntable 51 drives the multiple conveying grooves 511 to connect with the multiple positioning grooves 63 one by one through rotation, the multiple workpieces 2 can be conveyed into the positioning grooves 63 in sequence, that is, the multiple workpieces 2 can be positioned and conveyed to the workpiece output mechanism 6 in sequence through the transition conveying mechanism 5.

[0033] Then, a plurality of processing stations 7 may be provided on one side of the output belt 61 so that the multiple workpieces 2 output to the output belt 61 can be processed in sequence by the various processing stations 7 according to various steps.

[0034] Obviously, the present invention can effectively avoid the jamming of multiple workpieces 2 during continuous transportation by adding a screw conveying mechanism 4 and a transition conveying mechanism 5 connected in sequence between the workpiece input mechanism 3 and the workpiece output mechanism 6, thereby ensuring the smooth operation of the automated production line.

[0035] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
