[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1 to 3 This utility model discloses a rectangular assembly line transport device, comprising two speed-multiplying chain assemblies 1 and two roller transport assemblies 2. The two speed-multiplying chain assemblies 1 are arranged in parallel, and the two roller transport assemblies 2 are located at both ends of the speed-multiplying chain assemblies 1, forming a rectangular assembly line. A lifting plate 31 is slidably mounted at the end of the speed-multiplying chain assemblies 1, and the lifting plate 31 is located in the middle of the speed-multiplying chain assemblies 1. Multiple transport rollers 32 are rotatably mounted on the lifting plate 31. A lifting drive component 33 is fixedly mounted on the speed-multiplying chain assemblies 1, and the output end of the lifting drive component 33 is fixedly connected to the lifting plate 31. Multiple transport plates 4 for transporting workpieces are provided on the speed-multiplying chain assemblies 1. A connecting pin for connecting the speed-multiplying chain assemblies 1 is fixedly mounted at the bottom corner of the transport plate 4. Support plates are fixedly mounted on both sides of the bottom of the transport plate 4. At least one transport roller 32 is connected to a rotation drive component 5. After installation, the transport plane of the roller transport assembly 2 is higher than that of the speed-multiplying chain assemblies 1. After the lifting plate 31 is raised, the transport plane of the transport roller 32 is flush with that of the roller transport assembly 2.

[0036] Specifically, by setting up a liftable lifting plate 31 and a transport roller 32, when the double-speed chain assembly 1 inside the transport plate 4 transports to the corner position, the lifting plate 31 is raised, and the transport roller 32 lifts the transport plate 4 through the support plate, so that the transport plane of the transport roller 32 is flush with the roller transport assembly 2, and the rotation drive 5 is activated to make the transport plate 4 enter the roller transport assembly 2.

[0037] In this way, by setting up a liftable transport roller 32, it is easy and quick to complete the transfer of the various transport components of the rectangular assembly line chain. The transport roller 32, together with the lifting plate 31 and the lifting drive component 33, has a simple structure and low operating cost.

[0038] In some feasible embodiments, the double-speed chain assembly 1 includes two tracks, each containing a chain structure, both driven by the same motor. When the connecting pin of the transport plate 4 enters the track, it is placed on the chain structure and moves horizontally along with it. The roller transport assembly 2 includes a motor-driven roller; when the support plate of the transport plate 4 is placed on the roller, it is driven to move horizontally by the roller. Both the double-speed chain assembly 1 and the roller transport assembly 2 are supported on the ground by brackets. Both the double-speed chain assembly 1 and the roller transport assembly 2 are existing technologies and will not be described in detail here.

[0039] The transport plate 4 is a tooling set according to the transported components, the connecting pin is the placement end set according to the chain structure of the double speed chain assembly 1, and the support plate is the support set according to the height difference between the double speed chain assembly 1 and the roller transport assembly 2 and the height of the connecting pin, so that the transport roller 32 can lift the transport plate 4 across the double speed chain assembly 1.

[0040] A support frame is installed on the ground below one end of the double-speed chain assembly 1. A through hole is provided at the top corner of the support frame, and a support rod is slidably installed in the through hole. The lifting plate 31 is fixedly installed on the top of the support rod. The lifting drive component 33 is located between the lifting plate 31 and the support frame. The lifting drive component 33 can be an electric push rod, a cylinder, a hydraulic rod, etc. The transport roller 32 is a roller of the same specification as the roller transport assembly 2. Vertical plates are fixedly installed on both sides of the upper end of the lifting plate 31. The transport roller 32 is installed between the two vertical plates. In use, the transport roller 32 rises from between the two tracks of the double-speed chain assembly 1. The rotation drive component 5 can be a drive motor. The transport roller 32 is connected to the drive motor.

[0041] During installation, the transport plane of the roller transport assembly 2 is higher than that of the double-speed chain assembly 1. After the lifting plate 31 is raised, the transport plane of the transport roller 32 is flush with that of the roller transport assembly 2. The height difference between the roller transport assembly 2 and the double-speed chain assembly 1 is set according to the transport plate 4, so that after the lifting plate 31 lifts the transport plate 4, the sliding of the transport plate 4 is not affected by the double-speed chain assembly 1.

[0042] As a specific embodiment of the rectangular assembly line transport device provided in the application, please refer to 2. The lifting drive component 33 includes a base 331, which is fixedly installed on the speed-double chain assembly 1. A lifting motor 332 is fixedly installed on the base 331. A cam 333, which is rotatably installed on the base 331, is fixedly connected to the output end of the lifting motor 332. A plurality of return springs 334 are provided between the base 331 and the lifting plate 31.

[0043] Overall, by setting up the lifting motor 332 and the cam 333, it is easy to quickly lift the lifting plate 31 and realize the lifting of the lifting plate 31.

[0044] Furthermore, there are two cams 333, located on both sides of the lifting plate 31.

[0045] It should be understood that by setting two cams 333, the force on the lifting plate 31 can be evenly distributed when it is raised, thus improving the smoothness of the movement.

[0046] Furthermore, the arc surface where the remote point of cam 333 is located is an arc surface with the cam 333 rotation axis as the axis, and the central angle is not less than 90°.

[0047] It should be understood that by setting an arc surface and a central angle of not less than 90°, the cam 333 has a position of not less than one-quarter that can support the lifting plate 31 at a set height, which facilitates better effective support and reduces the impact of the rotation error of the cam 333.

[0048] In some feasible embodiments, the base 331 includes a rectangular top plate and four legs. The base 331 is provided with four through holes on which support columns can be slidably installed. The lifting plate 31 is fixed to the top of the support column. The return spring 334 is sleeved on the outside of the support column. Two cams 333 are connected by a round shaft. Alternatively, a dual-head output motor can be used to drive the cams 333 to rotate synchronously.

[0049] As another specific embodiment of the rectangular assembly line transport device provided in the application, please refer to Figure 1 and Figure 3 The rotating drive component 5 includes a first sprocket set 51, which is fixedly installed on the roller transport assembly 2 and drivenly connected to the roller transport assembly 2. A second sprocket set 52 is fixedly installed on the lifting plate 31 and connected to the transport roller 32. The sprockets of the first sprocket set 51 away from the roller transport assembly 2 are fixedly connected to a drive gear 53, and the sprockets of the second sprocket set 52 away from the transport roller 32 are fixedly connected to a driven gear 54. After the lifting plate 31 is raised, the driven gear 54 meshes with the drive gear 53.

[0050] It should be understood that by setting the rotation drive component 5, the roller transport assembly 2 drives the transport roller 32 to rotate, maintaining the synchronization between the various transport structures and making the workpiece transfer process smoother.

[0051] Furthermore, it also includes multiple third sprocket sets 55, which are mounted at the ends of adjacent transport rollers 32.

[0052] It should be understood that by setting a third sprocket set 55 between two adjacent transport rollers 32, it is convenient to make the transport rollers 32 run synchronously.

[0053] Furthermore, limit baffles 56 are fixedly installed on both sides of the lifting plate 31 at the end of the transport direction. Limit baffles 56 are fixedly installed with limit switches, and the limit switches are electrically connected to the lifting drive component 33.

[0054] It should be understood that by setting limit switches, the automatic control of the lifting drive component 33 is facilitated.

[0055] In some feasible configurations, the first sprocket set 51, the second sprocket set 52, and the third sprocket set 55 are all commonly used sprocket and chain drive assemblies, with the driving gear 53 and driven gear 54 operating in a 1:1 ratio. A connecting rib is fixedly connected to the side of the lifting plate 31, and a mounting plate is fixedly connected to the connecting rib. The second sprocket set 52 is mounted on the mounting plate. A support rod is provided on the ground. One sprocket of the first sprocket set 51 and the driving gear 53 are mounted on the support rod. The rotating shaft of the driven gear 54 is slidably connected to the support rod. To ensure compatibility between the roller conveying assembly 2 and the conveying roller 32 in terms of transmission direction, multiple driving gears 53 are provided to adjust the rotation direction.

[0056] The limit baffle 56 is a rectangular plate, and the limit switch can be a distance sensor, proximity switch, etc. The limit baffle 56 blocks the transport plate 4 and positions the stop position of the transport plate 4. After the transport plate 4 triggers the limit switch, the lifting drive 33 is started to perform the corresponding action.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
