Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation production, in particular, relates to a conveying device. BACKGROUND

[0002] Traditional assembly line generally adopts belt drive mode, and drives two groups of transmission belts to transport products through a driving device. The assembly line is also provided with a jacking mechanism, and the jacking mechanism is used to position the carrier on the assembly line, so as to improve the efficiency of the assembly line.

[0003] In actual production operation, the width of the assembly line needs to be adjusted according to different specifications of products. When the width of the assembly line is adjusted, manual operation is needed. After the width of the assembly line is adjusted, the jacking mechanism needs to be adjusted. Specifically, the center of the assembly line is calculated by measurement and calculation, and the center of the jacking mechanism is coincided with the center of the assembly line, so that the centering of the jacking mechanism and the assembly line is completed.

[0004] Such adjustment mode depends on manual operation, and has the problem of low efficiency, and the centering accuracy of the jacking mechanism is difficult to guarantee. CONTENT OF THE UTILITY MODEL

[0005] Therefore, the present application provides a conveying device to solve the problem of low efficiency in adjusting the width of the assembly line and centering the jacking mechanism after replacing products in the assembly line.

[0006] An embodiment of the present application provides a conveying device, comprising a base plate. The conveying device further comprises an assembly line assembly, a jacking mechanism and an adjusting mechanism. The assembly line assembly comprises a first track and a second track which are parallel and spaced apart on the base plate. The first track is fixedly connected to the base plate. The second track is slidingly connected to the base plate along a first direction. The jacking mechanism is arranged on the base plate and located between the first track and the second track along the first direction. The jacking mechanism is configured to be movable along the first direction. The adjusting mechanism comprises a first driving assembly and a second driving assembly. The first driving assembly is connected to the second track to drive the second track to move along the first direction. The second driving assembly is connected to the jacking mechanism to drive the jacking mechanism to move along the first direction.

[0007] The second track and the jacking mechanism are both movable along the first direction, so that the assembly line assembly can adapt to products of different sizes. At the same time, the first driving assembly is connected to the second track, and the second driving assembly is connected to the jacking mechanism. When the width of the assembly line assembly and the position of the jacking mechanism need to be adjusted, an automatic adjustment process can be realized without manually moving the second track and the jacking mechanism. Moreover, through the independent first driving assembly and the second driving assembly, more accurate control can be realized, which improves the efficiency and also improves the adjustment accuracy.

[0008] In some embodiments of the present application, the adjusting mechanism further comprises a synchronization assembly. The synchronization assembly is connected with the first driving assembly and the second driving assembly, so that the second track and the jacking mechanism are simultaneously moved along the first direction to approach or move away from the first track.

[0009] The adjusting mechanism further comprises a synchronization assembly connected with the first driving assembly and the second driving assembly, so that the movement of the second track and the jacking mechanism along the first direction is synchronized, and the second track and the jacking mechanism can simultaneously approach or move away from the first track. The width adjustment of the assembly line and the adjustment of the jacking mechanism can be completed at one time, further improving the efficiency.

[0010] In some embodiments of the present application, along the first direction, the distance between the jacking mechanism and the second track is equal to the distance between the jacking mechanism and the first track.

[0011] In this way, it is helpful to ensure that along the first direction, the center of the jacking mechanism and the center of the assembly line are coincident, and when the jacking mechanism jacks the product, the force acting on the product is balanced and uniform.

[0012] In some embodiments of the present application, the first driving assembly comprises a first connecting seat, a first lead screw and a first driving member. The first connecting seat is fixedly connected to the second track. The first lead screw passes through the first connecting seat along the first direction and is threadedly engaged with the first connecting seat. The first lead screw is configured to rotate about its axis to drive the first connecting seat to move along the first direction. The first driving member is connected with the first lead screw. The first driving member is used to drive the first lead screw to rotate, so that when the first connecting seat moves along the first direction, the second track can be driven to move along the first direction. The second driving assembly comprises a second connecting seat, a second lead screw and a second driving member. The second connecting seat is fixedly connected to the jacking mechanism. The second lead screw passes through the second connecting seat along the first direction and is threadedly engaged with the second connecting seat. The second lead screw is configured to rotate about its axis to drive the second connecting seat to move along the first direction. The second driving member is connected with the second lead screw. The second driving member is used to drive the second lead screw to rotate, so that when the second connecting seat moves along the first direction, the jacking mechanism can be driven to move along the first direction.

[0013] The first driving member drives the first lead screw to rotate, which can drive the second track to move along the first direction, so as to adjust the distance between the first track and the second track and realize the automatic adjustment of the width of the assembly line. The first driving member can be a hand wheel, and can also be a driving motor or a driving cylinder. The second driving member drives the second lead screw to rotate, which can drive the jacking mechanism to move along the first direction, so as to adjust the position of the jacking mechanism and realize the automatic adjustment of the position of the jacking mechanism relative to the first track and the second track. The second driving member can be a hand wheel, and can also be a driving motor or a driving cylinder.

[0014] In some embodiments of the present application, the first driving member is a first synchronous wheel, and the second driving member is a second synchronous wheel. The first synchronous wheel is connected with the first screw rod to drive the first synchronous wheel to rotate. The second synchronous wheel is connected with the second screw rod to drive the second synchronous wheel to rotate. The synchronous assembly comprises a synchronous belt. The synchronous belt is engaged with the first synchronous wheel and the second synchronous wheel to drive the first synchronous wheel and the second synchronous wheel to rotate simultaneously.

[0015] When the first synchronous wheel rotates or the second synchronous wheel rotates, the first screw rod and the second screw rod can be driven to rotate simultaneously under the action of the synchronous belt, so that the second track and the lifting mechanism are simultaneously driven to move in the first direction, further improving the adjustment efficiency.

[0016] In some embodiments of the present application, the pitch of the first screw rod is equal to the pitch of the second screw rod, and the number of teeth of the first synchronous wheel is equal to half the number of teeth of the second synchronous wheel.

[0017] In this way, the first synchronous wheel rotates one circle, and the second synchronous wheel rotates half a circle correspondingly. Correspondingly, the second track moves a distance twice the distance of the lifting mechanism in the first direction. When the first synchronous wheel or the second synchronous wheel is driven to rotate, the width of the synchronous adjustment assembly and the centering of the lifting mechanism are realized.

[0018] In some embodiments of the present application, the pitch of the first screw rod is equal to twice the pitch of the second screw rod, and the number of teeth of the first synchronous wheel is equal to the number of teeth of the second synchronous wheel.

[0019] The first synchronous wheel and / or the second synchronous wheel rotates one circle, and the second track moves a distance twice the distance of the lifting mechanism in the first direction. When the first synchronous wheel or the second synchronous wheel is driven to rotate, the width of the synchronous adjustment assembly and the centering of the lifting mechanism are realized.

[0020] In some embodiments of the present application, the conveying device further comprises a first sensing member, a second sensing member and a third sensing member. The first sensing member, the second sensing member and the third sensing member are arranged at intervals in the first direction on the base plate. The base plate has a first position, a second position and a third position arranged in sequence in the first direction. The first sensing member is used to sense that the second track is present at the first position, the second sensing member is used to sense that the second track is present at the second position, and the third sensing member is used to sense that the second track is present at the third position.

[0021] In the first direction, the lifting mechanism is arranged between the first track and the second track, and the first position and the third position correspond to two limit positions of the second track moving in the first direction respectively. If the first position is the position closest to the first track, then the third position is the position farthest from the first track. The second position represents the origin position. In this way, it is beneficial to prevent the second track from being adjusted and the lifting mechanism from being scratched, thereby damaging the lifting mechanism.

[0022] In some embodiments of the present application, the pipeline assembly further comprises a slide rail set and a first connecting plate. The slide rail set comprises a first slide rail and a second slide rail which are parallel and spaced apart on the base plate. The first slide rail and the second slide rail both extend along the first direction. The first connecting plate is slidingly connected to the first slide rail and the second slide rail. The second track is connected to a side of the first connecting plate away from the base plate.

[0023] The second track is connected to the first connecting plate and the slide rail set, and the parallel and spaced first slide rail and second slide rail help to make the movement of the second track along the first direction more stable.

[0025] The jacking assembly is arranged on the second connecting plate which can slide along the first direction relative to the base plate, and driving the second connecting plate to move along the first direction can adjust the position of the jacking mechanism relative to the first track and the second track. The second connecting plate is slidingly connected to the first slide rail and the second slide rail, which helps to improve the stability of the movement of the entire jacking mechanism along the first direction.

[0036] The embodiments of the present application provide a conveying device, comprising a base plate. The conveying device further comprises an assembly of flow line, a jacking mechanism and an adjusting mechanism. The assembly of flow line comprises a first track and a second track which are parallel and spaced apart on the base plate. The first track is fixedly connected to the base plate. The second track is slidingly connected to the base plate along a first direction. The jacking mechanism is arranged on the base plate and located between the first track and the second track along the first direction.

[0037] The second track and the jacking mechanism can move along the first direction, and the assembly line component can adapt to products of different sizes. Meanwhile, the first driving assembly is connected to the second track, and the second driving assembly is connected to the jacking mechanism to move. When it is necessary to adjust the width of the assembly line component and the position of the jacking mechanism, an automatic adjustment process can be realized without manually moving the second track and the jacking mechanism. Through the independent first driving assembly and the second driving assembly, more accurate control can be realized, and the efficiency can be improved while the adjustment accuracy can also be improved.

[0038] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] Referring to Figure 1 An embodiment of the present application provides a conveying device 100 comprising a base plate 1. The conveying device 100 further comprises an assembly line component 2, a jacking mechanism 3 and an adjustment mechanism. The assembly line component 2 comprises a first track 21 and a second track 22 which are parallel and spaced apart on the base plate 1. The first track 21 is fixedly connected to the base plate 1. The second track 22 is slidingly connected to the base plate 1 along a first direction X. The jacking mechanism 3 is arranged on the base plate 1 and located between the first track 21 and the second track 22 along the first direction X. The jacking mechanism 3 is configured to be movable along the first direction X. The adjustment mechanism comprises a first driving assembly 41 and a second driving assembly 42. The first driving assembly 41 is connected to the second track 22 to drive the second track 22 to move along the first direction X. The second driving assembly 42 is connected to the jacking mechanism 3 to drive the jacking mechanism 3 to move along the first direction X.

[0040] The second track 22 and the jacking mechanism 3 can move along the first direction X, and the assembly line component 2 can adapt to products of different sizes. Meanwhile, the first driving assembly 41 is connected to the second track 22, and the second driving assembly 42 is connected to the jacking mechanism 3 to move. When it is necessary to adjust the width of the assembly line component 2 and the position of the jacking mechanism 3, an automatic adjustment process can be realized without manually moving the second track 22 and the jacking mechanism 3. Through the independent first driving assembly 41 and the second driving assembly 42, more accurate control can be realized, and the efficiency can be improved while the adjustment accuracy can also be improved.

[0041] Referring to Figure 1 and Figure 2 In some embodiments, the adjustment mechanism further comprises a synchronization assembly 43. The synchronization assembly 43 is connected to the first driving assembly 41 and the second driving assembly 42 to make the second track 22 and the jacking mechanism 3 move along the first direction X at the same time to approach or move away from the first track 21.

[0042] The adjusting mechanism further comprises a synchronizing assembly 43 connected with the first driving assembly 41 and the second driving assembly 42, so that the movement of the second track 22 and the jacking mechanism 3 along the first direction X is synchronized, and the second track 22 and the jacking mechanism 3 can approach or move away from the first track 21 at the same time. The width adjustment of the assembly line 2 and the adjustment of the jacking mechanism 3 can be completed at one time, further improving the efficiency.

[0043] In some embodiments, along the first direction X, the distance between the jacking mechanism 3 and the second track 22 is equal to the distance between the jacking mechanism 3 and the first track 21.

[0044] In this way, it helps to ensure that along the first direction X, the center of the jacking mechanism 3 and the center of the assembly line 2 are coincident, and when the jacking mechanism 3 jacks the product, the product is balanced and uniform in force.

[0045] In some embodiments, the first driving assembly 41 comprises a first connecting seat 411, a first lead screw 412 and a first driving member. The first connecting seat 411 is fixedly connected to the second track 22. The first lead screw 412 passes through the first connecting seat 411 along the first direction X and is threadedly engaged with the first connecting seat 411. The first lead screw 412 is configured to rotate about its axis to drive the first connecting seat 411 to move along the first direction X. The first driving member is connected with the first lead screw 412. The first driving member is used to drive the first lead screw 412 to rotate, so that when the first connecting seat 411 moves along the first direction X, it can drive the second track 22 to move along the first direction X.

[0046] The first driving member drives the first lead screw 412 to rotate, which drives the second track 22 to move along the first direction X, thereby adjusting the distance between the first track 21 and the second track 22, realizing the automatic width adjustment of the assembly line. The first driving member can be a hand wheel, but also can be a driving motor or a driving cylinder.

[0047] In some embodiments, the second driving assembly 42 comprises a second connecting seat 421, a second lead screw 422 and a second driving member. The second connecting seat 421 is fixedly connected to the jacking mechanism 3. The second lead screw 422 passes through the second connecting seat 421 along the first direction X and is threadedly engaged with the second connecting seat 421. The second lead screw 422 is configured to rotate about its axis to drive the second connecting seat 421 to move along the first direction X. The second driving member is connected with the second lead screw 422. The second driving member is used to drive the second lead screw 422 to rotate, so that when the second connecting seat 421 moves along the first direction X, it can drive the jacking mechanism 3 to move along the first direction X.

[0048] The second driving component drives the second lead screw 422 to rotate, which in turn drives the lifting mechanism 3 to move along the first direction X, thereby adjusting the position of the lifting mechanism 3 and automatically adjusting its position relative to the first track 21 and the second track 22. The second driving component can be a handwheel, a drive motor, or a drive cylinder.

[0049] In some embodiments, the adjusting mechanism may include only the first drive assembly 41 and the second drive assembly 42. Specifically, both the first and second drive assemblies are motors. The distance between the lifting mechanism 3 and the second track 22 along the first direction X can be ensured to be equal to the distance between the lifting mechanism 3 and the first track 21 by setting the speed ratio of the two motors or the pitch ratio of the first lead screw 412 and the second lead screw 422. Understandably, when the speed ratio of the motor driving the first lead screw 412 to the motor driving the second lead screw 422 is 2:1, the pitches of the first lead screw 412 and the second lead screw 422 should be the same; when the pitch ratio of the first lead screw 412 and the second lead screw 422 is 2:1, the speeds of the two motors should be the same.

[0050] In some embodiments, the first driving member is a first synchronous pulley 431, and the second driving member is a second synchronous pulley 432. The first synchronous pulley 431 is connected to a first lead screw 412 so that the first synchronous pulley 431 drives the first lead screw 412 to rotate. The second synchronous pulley 432 is connected to a second lead screw 422 so that the second synchronous pulley 432 drives the second lead screw 422 to rotate. The synchronization assembly 43 includes a synchronous belt 434. The synchronous belt 434 engages with both the first synchronous pulley 431 and the second synchronous pulley 432 to drive both the first synchronous pulley 431 and the second synchronous pulley 432 to rotate simultaneously.

[0051] When the first synchronous pulley 431 rotates or the second synchronous pulley 432 rotates, the first lead screw 412 and the second lead screw 422 can be driven to rotate simultaneously, thereby driving the second track 22 and the lifting mechanism 3 to move along the first direction X, further improving the adjustment efficiency.

[0052] In some embodiments, the synchronization component 43 further includes a drive motor 433 and a timing belt 434. The output shaft of the drive motor 433 can be connected to either the first timing pulley 431 or the second timing pulley 432. Figure 1 As shown, the output shaft of the drive motor 433 is connected to the first synchronous pulley 431, and the synchronous belt 434 is wound around the first synchronous pulley 431 and the second synchronous pulley 432. Thus, when the drive motor 433 drives the first synchronous pulley 431 to rotate, the second synchronous pulley 432 can also rotate synchronously. Furthermore, a tension pulley 435 is also provided between the first synchronous pulley 431 and the second synchronous pulley 432 to maintain the tension of the synchronous belt 434, helping to prevent the synchronous belt 434 from slipping.

[0053] It is appreciated that the synchronous belt 434 can also be a chain, which is arranged around the first and second synchronous wheels 431 and 432, and by driving the first or second synchronous wheel 431 or 432 to rotate, the first and second synchronous wheels 431 and 432 can be driven to rotate synchronously. The synchronous belt 434 can also be in the form of a middle gear, in which case the driving motor 433 can be connected to the middle gear, and the middle gear is connected to the first and second synchronous wheels 431 and 432 respectively.

[0054] In some embodiments, the pitch of the first screw rod 412 is equal to the pitch of the second screw rod 422, and the number of teeth of the first synchronous wheel 431 is equal to half of the number of teeth of the second synchronous wheel 432.

[0055] In this way, when the first synchronous wheel 431 rotates one round, the second synchronous wheel 432 rotates half a round correspondingly, and correspondingly, the second track 22 moves a distance twice as long as the distance moved by the lifting mechanism 3 in the first direction X. When the first or second synchronous wheel 431 or 432 is driven to rotate, the width of the synchronous adjustment assembly 2 and the centering of the lifting mechanism 3 are adjusted synchronously.

[0056] In some embodiments, the pitch of the first screw rod 412 is equal to twice the pitch of the second screw rod 422, and the number of teeth of the first synchronous wheel 431 is equal to the number of teeth of the second synchronous wheel 432.

[0057] When the first or second synchronous wheel 431 or 432 is driven to rotate, the width of the synchronous adjustment assembly 2 and the centering of the lifting mechanism 3 are adjusted synchronously.

[0058] In some embodiments, the number of teeth of the first and second synchronous wheels 431 and 432 can be different, and the pitches of the first and second screw rods 412 and 422 can be different, as long as the distance moved by the second track 22 in the first direction X is twice as long as the distance moved by the lifting mechanism 3.

[0059] Please refer to Figure 2In some embodiments, the conveying device 100 further comprises a first sensing member 51, a second sensing member 52 and a third sensing member 53. The first sensing member 51, the second sensing member 52 and the third sensing member 53 are arranged on the base plate 1 in the first direction X and are spaced apart from each other. The first sensing member 51, the second sensing member 52 and the third sensing member 53 are sequentially arranged away from the first track 21 in the first direction X. The base plate 1 has a first position, a second position and a third position arranged in the first direction X. The first sensing member 51 is configured to sense that the first position has the second track 22. The first position is defined as the position closest to the first track 21. The third sensing member 53 is configured to sense that the third position has the second track 22. The third position is defined as the position farthest from the first track 21. The second position is the origin position of the second track 22 moving in the first direction X.

[0060] In the first direction X, the jacking mechanism 3 is arranged between the first track 21 and the second track 22. The first sensing member 51 is arranged to prevent the jacking mechanism 3 from being damaged when adjusting the second track 22. It can be understood that the lengths of the first lead screw 412 and the second lead screw 422 are greater than the maximum distance that the second track 22 can be adjusted relative to the first track 21.

[0061] In some embodiments, the pipeline assembly 2 further comprises a slide rail set 23 and a first connecting plate 24. The slide rail set 23 comprises a first slide rail 231 and a second slide rail 232 arranged in parallel and spaced apart on the base plate 1. The first slide rail 231 and the second slide rail 232 both extend in the first direction X. The first connecting plate 24 is slidably connected to the first slide rail 231 and the second slide rail 232. The second track 22 is connected to the side of the first connecting plate 24 away from the base plate 1.

[0062] The second track 22 is connected to the first connecting plate 24 and the slide rail set 23. The first slide rail 231 and the second slide rail 232 arranged in parallel and spaced apart help to make the movement of the second track 22 in the first direction X more stable.

[0063] In some embodiments, the pipeline assembly 2 further comprises a slide rail set 23. The slide rail set 23 comprises a first slide rail 231 and a second slide rail 232 arranged in parallel and spaced apart on the base plate 1. The first slide rail 231 and the second slide rail 232 both extend in the first direction X. The jacking mechanism 3 comprises a second connecting plate 31 and a jacking assembly 32. The second connecting plate 31 is slidably connected to the first slide rail 231 and the second slide rail 232. The jacking assembly 32 is connected to the side of the second connecting plate 31 away from the base plate 1. The jacking assembly 32 is configured to detach the product or the carrier from the pipeline assembly 2.

[0064] The jacking assembly 32 is arranged on the second connecting plate 31 which can slide relative to the base plate 1 along the first direction X. Driving the second connecting plate 31 to move along the first direction X can adjust the position of the jacking mechanism 3 relative to the first rail 21 and the second rail 22. The second connecting plate 31 is slidingly connected to the first slide rail 231 and the second slide rail 232, which helps to improve the stability of the jacking mechanism 3 when moving along the first direction X.
