Description

Technical Field

[0001] The present invention belongs to the technical field of product conveyor lines, and particularly relates to a production assembly line with variable vertical pitch. Background Art

[0002] In modern manufacturing, the circulation line in the production workshop is one of the key equipment for achieving efficient production. However, the current application status of the circulation line has many limitations, seriously restricting the improvement of production efficiency and product quality.

[0003] From the perspective of application scenarios, the current circulation lines in production workshops are mainly concentrated in the use environments of planes and small jigs. This limitation stems from the characteristics of the circulation line itself, making the single circulation line body appear inadequate when facing some special requirements. For example, in industries such as electronic equipment manufacturing and automotive parts processing, as the product size and weight continue to increase, the requirements for jigs are also getting higher and higher. However, most of the existing single circulation line bodies cannot bear jigs with dimensions exceeding 300*300 mm and a weight exceeding 20 kg, and at the same time, they also require precise secondary positioning for handling tasks.

[0004] In terms of precise positioning and running speed, some circulation lines on the market that can carry large-size jigs and heavy weights are difficult to balance precise positioning and high-speed operation. In fields with extremely high precision requirements such as precision instrument manufacturing and aerospace parts production, if the circulation line cannot provide precise positioning, it will lead to product assembly deviations, affecting product performance and quality. And slow running speed will prolong the production cycle, reduce production efficiency, increase production costs, putting enterprises at a disadvantage in the market competition.

[0005] To solve the problems existing in the single circulation line body, a vertical double rail has been developed. Referring to the patent CN210213761U - A Vertical Double Rail, through the set non-centered coaxial transmission mechanism, the conveyor belts on the two conveyor mechanisms achieve the effect of synchronous operation, thereby increasing the size of the product jig plate that can be installed, enhancing the load-bearing capacity of the conveyor mechanism and the stable process structure, improving production precision while enhancing production efficiency, and thus solving the problems of the single circulation line body having a small jig for loading, light load, slow speed, and extremely poor stability during the production process of large-sized products.

[0006] However, the use scenario of this vertical double rail is single, that is, it is only applicable to large-size jigs. Then, when the circulation line body in the production workshop needs to carry small jigs and large jigs at the same time, two sets of circulation line bodies are required, occupying a large amount of production workshop space and increasing production costs at the same time.

[0060] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0061] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0062] In order to solve the problems such as the single use scenarios of the single-loop line body and the vertical double-track in the prior art, an embodiment of the present invention provides a production assembly line with variable vertical pitch.

[0063] As Figure 1 shown, a production assembly line with variable vertical pitch disclosed in this embodiment includes: a frame 10, a first line body 20, a second line body 30, and a first driving mechanism 50. The first line body 20 and the second line body 30 have the same structure and are arranged in parallel. A slide rail assembly 40 is provided on the frame 10. The first line body 20 and the second line body 30 are movably connected to the slide rail assembly 40 and move closer to or away from each other along the slide rail assembly 40 under the action of the first driving mechanism 50.

[0064] In this embodiment, it should be noted that both the first line body 20 and the second line body are loop line bodies. The first line body 20 and the second line body have the same structure and can operate independently.

[0065] In addition, the first line body 20 and the second line body are perpendicular and parallel to each other, and the distance between the first line body 20 and the second line body 30 is adjustable.

[0066] Specifically, a slide rail assembly 40 is provided on the frame 10. The first line body 20 and the second line body 30 are movably connected to the slide rail assembly 40 and can move relative to each other along the slide rail assembly 40.

[0067] The first driving mechanism 50 is respectively connected to the first line body 20 and the second line body 30 to drive the first line body 20 and the second line body 30 to move along the slide rail assembly 40, thereby realizing the adjustment of the distance between the first line body 20 and the second line body 30.

[0068] Therefore, in this embodiment, in view of the fact that the first line body 20 and the second line body 30 can operate independently, and the first line body 20 and the second line body 30 can respectively carry products of different specifications or the same specifications, the first line body 20 and the second line body 30 can work independently or synchronously.

[0069] For example, for the transportation of small-sized products, during the actual production and processing, the first line body 20 and the second line body 30 can adjust the distance between the first line body 20 and the second line body 30 through the first driving mechanism 50 according to the actual size of the products to be carried; in addition, the first line body 20 or the second line body 30 can be selected to operate independently according to production requirements, or the first line body 20 and the second line body 30 can be selected to operate simultaneously. When the first line body 20 and the second line body 30 operate simultaneously, they can operate synchronously or staggeredly, and the operating speeds of the first line body 20 and the second line body 30 can be the same or different.

[0070] For the transportation of large-sized products, according to the actual size of the large-sized products, the distance between the first line body 20 and the second line body 30 is adjusted through the first driving mechanism 50, and the jig for carrying the large-sized products is placed on the first line body 20 and the second line body 30. At this time, the first line body 20 and the second line body 30 move synchronously, so as to realize the transportation of large-sized products of different specifications.

[0071] Therefore, a vertically variable-spacing production and assembly line provided in this embodiment at least includes two independent first line bodies 20 and second line bodies 30. The first line body 20 and the second line body 30 are arranged in parallel on the frame 10, and a slide rail assembly 40 is arranged on the frame 10. The first driving mechanism 50 drives the first line body 20 and the second line body 30 to approach or move away from each other along the slide rail assembly 40, so as to adjust the distance between the first line body 20 and the second line body 30; the first line body 20 and the second line body 30 can work independently or work simultaneously, combined with the adjustable distance between the first line body 20 and the second line body 30, so as to realize the transmission of small jigs and large jigs of different sizes, and further realize the transportation of small-sized products and large-sized products of different specifications. The vertically variable-spacing production and assembly line can be applied to different application scenarios, is flexible in operation, occupies a small space, and saves production costs.

[0072] As a preferred embodiment, the specific structure of the first driving mechanism 50 and the cooperation structure of the first driving mechanism 50 with the first line body 20, the second line body 30 and the frame 10 are optimized in this embodiment.

[0073] Specifically, as Figure 2 shown, the first driving mechanism 50 includes a plurality of first motor components 51 and a plurality of first lead screw components 52. The plurality of first lead screw components 52 are all arranged in parallel with the slide rail assembly 40. Each first motor component 51 is respectively connected to a first lead screw component 52 to drive the first lead screw component 52 to rotate. The first lead screw components 52 are respectively connected to the first line body 20 and the second line body 30. The first line body 20 and the second line body 30 approach or move away from each other during the rotation of the first lead screw components 52.

[0074] In this embodiment, considering the dimensions of the first line body 20 and the second line body 30 in the length direction, in order to ensure the stability of the first line body 20 and the second line body 30 during relative movement, the number of the first screw rod assemblies 52 is at least set to two groups. The two groups of first screw rod assemblies 52 are symmetrically distributed along the central axes of the first line body 20 and the second line body 30. The number of the first motor assemblies 51 matches the number of the first screw rod assemblies 52, thereby ensuring the stability and accuracy of the first line body 20 and the second line body 30 during relative movement.

[0075] The first screw rod assembly 52 is installed on the frame 10 and can be driven to rotate by the first motor assembly 51.

[0076] Preferably, the slide rail assemblies 40 are also set to multiple groups. The multiple slide rail assemblies 40 are arranged in a staggered manner with the multiple groups of first screw rod assemblies 52, further ensuring the stability and accuracy of the relative movement of the first line body 20 and the second line body 30.

[0077] In some preferred embodiments, the number of the first screw rod assemblies 52 is set to three groups. One group is arranged along the central axes of the first line body 20 and the second line body 30, and the other two groups of first screw rod assemblies 52 are symmetrically distributed along the central first screw rod assembly 52. Similarly, the number of the first motor assemblies 51 matches the number of the first screw rod assemblies 52.

[0078] In this embodiment, the multiple groups of first screw rod assemblies 52 have the same structure, and the multiple groups of first motor assemblies 51 adopt motors of the same specification, thereby ensuring that the multiple groups of first screw rod assemblies 52 have the same rotation speed.

[0079] When adjusting the distance between the first line body 20 and the second line body 30, the multiple groups of first screw rod assemblies 52 need to rotate synchronously. Then, the multiple groups of first motor assemblies 51 need to work synchronously.

[0080] Therefore, preferably, the first driving mechanism 50 further includes a second motor assembly 53 and a second screw rod assembly 54. The second motor assembly 53 is connected to the second screw rod assembly 54 to drive the second screw rod assembly 54 to rotate. The second screw rod assembly 54 is arranged at the same end of several first motor assemblies 51 and is connected to the several first motor assemblies 51, so that the multiple first motor assemblies 51 drive the multiple groups of first screw rod assemblies 52 to rotate synchronously.

[0081] The second screw rod assembly 54 is installed at one end of the frame 10 through a connecting member 55 and is arranged parallel to the first line body 20 and the second line body 30, and is perpendicular to the multiple groups of first screw rod assemblies 52 at the same time.

[0082] Specifically, a first gear member is provided on the output shaft of the second motor assembly 53, and a second gear member for synchronously rotating a plurality of second lead screw assemblies 54 is provided on the second lead screw assembly 54. A third gear member is provided at the opposite end of the first motor assembly 51 to the second lead screw assembly 54. The first gear member meshes with one of the second gear members on the second lead screw assembly 54, and the remaining plurality of second gear members respectively mesh with a third gear member, so as to realize the synchronous operation of a plurality of first motor assemblies 51 controlled by the second motor assembly 53, and further realize the synchronous rotation of multiple groups of first lead screw assemblies 52, thereby ensuring the stability and accuracy when the first line body 20 and the second line body 30 move relative to each other.

[0083] As a preferred embodiment, the connection structure between the first line body 20 and the second line body 30 and the frame 10 is optimized in this embodiment.

[0084] Specifically, a vertical variable pitch production and assembly line provided in this embodiment further includes a plurality of first support components 60 and a plurality of second support components 70. The first line body 20 is movably connected to the slide rail assembly 40 and the first lead screw assembly 52 through the plurality of first support components 60; the second line body 30 is movably connected to the slide rail assembly 40 and the first lead screw assembly 52 through the plurality of second support components 70.

[0085] The cooperation structure of the plurality of first support components 60 and the plurality of second support components 70 with the slide rail assembly 40, the first lead screw assembly 52, and the first line body 20 and the second line body 30 is as follows:

[0086] The number of the first support components 60 and the second support components 70 is the same as the number of the first lead screw assembly 52 and the slide rail assembly 40.

[0087] The first ends of the plurality of first support components 60 are fixedly connected to the first line body 20. First sliders are provided at the bottoms of some of the first support components 60, and the first sliders are slidably matched with the slide rail assembly 40. The bottoms of some of the first support components 60 are sleeved on the first lead screw assembly 52 and are screwed to the first lead screw assembly 52, and move along the first lead screw assembly 52 during the rotation of the first lead screw assembly 52, thereby driving the first line body 20 to move along the slide rail assembly 40.

[0088] Similarly, the first ends of the plurality of second support components 70 are fixedly connected to the first line body 20. Second sliders are provided at the bottoms of some of the second support components 70, and the second sliders are slidably matched with the slide rail assembly 40. The bottoms of some of the second support components 70 are sleeved on the first lead screw assembly 52 and are screwed to the first lead screw assembly 52, and move along the first lead screw assembly 52 during the rotation of the first lead screw assembly 52, thereby driving the second line body 30 to move along the slide rail assembly 40.

[0089] Therefore, during the rotation of the first lead screw assembly 52, the first wire body 20 and the second wire body 30 are forced to move relative to each other through the first support assembly 60 and the second support assembly 70, thereby achieving the purpose of adjusting the distance between the first wire body 20 and the second wire body 30.

[0090] In this embodiment, as a preferred embodiment, the specific structures of the first wire body 20 and the second wire body 30 are optimized.

[0091] As Figure 3 shown, the first wire body 20 includes a first conveying assembly 21, a first track assembly 22, a first support plate assembly 23, a second driving mechanism 24, a first driving wheel assembly 25, and a first driven wheel assembly 26. The first driving wheel assembly 25 and the first driven wheel assembly 26 are arranged at both ends of the first support plate assembly 23. The first conveying assembly 21 is wound around the first driving wheel assembly 25 and the first driven wheel assembly 26. The second driving mechanism 24 is connected to the first driving wheel assembly 25 to drive the first driving wheel assembly 25 to rotate. The first track assembly 22 is arranged along the circumference of the first conveying assembly 21 on the outside of the first conveying assembly 21. A plurality of first sliding seat assemblies 27 are arranged on the first track assembly 22. The first sliding seat assemblies 27 are connected to the first conveying assembly 21 and slide along the first track assembly 22 during the conveying process of the first conveying assembly 21. The first support plate assembly 23 is movably connected to the slide rail assembly 40.

[0092] In this embodiment, the first wire body 20 adopts a circulating wire body. The first track assembly 22 is located outside the first conveying assembly 21. The linear track of the first track assembly 22 is arranged parallel to the linear conveying part of the first conveying assembly 21, and the circular track of the first track assembly 22 is arranged concentrically with the circular conveying part of the first conveying assembly 21.

[0093] In addition, in this embodiment, a plurality of first sliding seat assemblies 27 are evenly distributed along the circumference of the first track assembly 22. The second driving mechanism 24 adopts a motor. The second driving mechanism 24 drives the first driving wheel assembly 25 to rotate, thereby driving the first conveying assembly 21 to operate, and further driving a plurality of first sliding seat assemblies 27 to operate along the first track assembly 22. The first support plate assembly 23 is fixedly connected to the top of the first support assembly 60. The first support plate assembly 23 is slidably connected to the slide rail assembly 40 through the first support assembly 60, and is rotationally connected to the first lead screw assembly 52 through the first support assembly 60 at the same time.

[0094] In this embodiment, as a preferred embodiment, the first wire body 20 further includes a first induction sensor 28. The first induction sensor 28 is arranged on the first support plate assembly 23 to detect the position of the first sliding seat assembly 27. It can also be understood that the in-place situation of the first sliding seat assembly 27 can be detected through the first induction sensor 28.

[0095] As a preferred embodiment, the assembly structure of the first conveying component 21 is optimized.

[0096] Specifically, the first conveying component 21 adopts a first chain component, and the first line body 20 further includes a plurality of first chain support components 29. The plurality of first chain support components 29 are fixedly installed on the first support plate component 23 along the circumference of the first conveying component 21. The first chain support component 29 is provided with a first chain slot through which the first conveying component 21 can pass, so that the first conveying component 21 moves along the first chain slot.

[0097] The provided first chain support component 29 can limit the first conveying component 21 and ensure the stability of the first conveying component 21 during the movement process.

[0098] As a preferred embodiment, the matching structure of the first track component 22 and the first sliding seat component 27 is optimized.

[0099] Specifically, as Figures 6-7 shown, the first sliding seat component 27 includes a first connecting plate 271 and a first roller group 272 arranged on the first connecting plate 271. The first roller group 272 is arranged on both sides of the first track component 22 and is slidably connected to the first track component 22. The first connecting plate 271 is locked and fixed to the first conveying component 21 through a first mounting fastener 273.

[0100] The specific structure of the first track component 22 is as Figures 4-5 shown. Taking a cross-section along the direction perpendicular to the conveying direction of the first conveying component 21, the opposite sides of the first track component 22 are provided with first roller slots 221 matching the first roller group 272, and the first roller group 272 slides along the first roller slots 221.

[0101] In addition, a first positioning slot 222 is provided on the opposite side surfaces of the first track component 22 and the first support plate component 23. The opposite end of the first support plate component 23 to the first track component 22 is embedded in the first positioning slot 222 to fix the first track component 22 and prevent the first track component 22 from shifting during use, ensuring the stability of the transmission of the first sliding seat component 27.

[0102] In this embodiment, the second line body 30 has the same structure as the first line body 20. Therefore, the structure of the second line body 30 is:

[0103] The second line body 30 includes a second conveying component, a second track component, a second support plate component, a third driving mechanism, a second driving wheel component and a second driven wheel component. The second driving wheel component and the second driven wheel component are arranged at both ends of the second support plate component. The second conveying component is wound around the second driving wheel component and the second driven wheel component. The third driving mechanism is connected to the second driving wheel component to drive the second driving wheel component to rotate. The second track component is arranged on the outside of the second conveying component along one week of the second conveying component. A plurality of second sliding seat components are arranged on the second track component. The second sliding seat component is connected to the second conveying component and slides along the second track component during the conveying process of the second conveying component.
