Description

Technical Field

[0002] In the production process of lithium batteries, since the lithium batteries on the pallets require multiple processing steps, it is often necessary to change the pallets on conveyor line one to conveyor line two, which is perpendicular to conveyor line one, for further processing.

The driving shaft passes through the frame and is fixedly connected to the output end of the motor. Both the driving shaft and the driven shaft are rotatably connected to the side walls of the frame. The driving shaft and the driven shaft are arranged at both ends of the conveyor belt. The motor drives the driving shaft to rotate, and the conveyor belt can then transport pallets.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] Example 1:

[0051] like Figure 1-Figure 4 As shown, an embodiment of the present utility model provides a line changing device, comprising a carrier 1, a first drive mechanism, a second drive mechanism, a roller assembly and a roller assembly;

[0052] The first driving mechanism and the second driving mechanism are both installed in the carrier 1;

[0053] The roller assembly includes a plurality of rollers 2, the plurality of rollers 2 are arranged in a row along a first direction, and the axes of the plurality of rollers 2 are located in the same plane;

[0054] The roller assembly includes a plurality of rollers 3, the plurality of rollers 3 are arranged in a row at intervals along the second direction, and the axes of the plurality of rollers 3 are located in the same plane;

[0055] The upper surface of the carrier 1 is a mounting table;

[0056] The plurality of rollers 2 and the plurality of rollers 3 are all installed in the carrier frame 1, and the upper end surfaces of the plurality of rollers 2 and the upper end surfaces of the plurality of rollers 3 are located in the same plane, and the upper end surfaces of the plurality of rollers 2 and the upper end surfaces of the plurality of rollers 3 are not lower than the installation table;

[0058] The second driving mechanism is in transmission connection with the plurality of rollers 3 and is used for driving the plurality of rollers 3 to rotate around their respective axes.

[0059] The plurality of rollers 2 cooperate to drive the tray to move along a first direction, and the plurality of rollers 3 cooperate to drive the tray to move along a second direction, wherein the first direction is perpendicular to the second direction.

[0060] When the pallet on conveyor line one needs to be changed to conveyor line two, conveyor line one transports the pallet to the line changing device, and the first driving mechanism and the multiple rollers 2 are connected through the transmission, driving the multiple rollers 2 to rotate around their respective axes, so that the multiple rollers 2 cooperate to drive the pallet to move in the first direction until the pallet stops directly above the carrier 1, and the second driving mechanism and the multiple rollers 3 are connected through the transmission, driving the multiple rollers 3 to rotate around their respective axes, and the multiple rollers 3 in the roller assembly cooperate to drive the pallet to move in the second direction, transporting the pallet to conveyor line two, completing the line changing operation, the pallet does not need to rotate, and the rollers 2 and 3 do not move at the same time, which will not interfere with the movement direction of the pallet, the movement direction of the pallet is not easy to deviate, and the transportation stability is better.

[0061] Further, such as Figure 1 As shown, two groups of roller assemblies are provided, and the two groups of roller assemblies are symmetrically arranged at both ends of the roller assembly.

[0062] There are two groups of roller assemblies, which are symmetrically arranged at both ends of the roller assembly, so that both sides of the pallet can be driven to move when the pallet is transported along the first direction, and the stability during transportation is better.

[0063] According to one embodiment of the present invention, Figure 2 As shown, the carrier frame 1 includes a bottom plate 101 and two support plates 102;

[0064] Two support plates 102 are installed at both ends of the bottom plate 101 , and the roller 2 is rotatably connected to the support plates 102 .

[0065] The length direction of the support plate 102 is the same as the first direction, and the multiple rollers 2 are rotatably connected to the support plate 102. Furthermore, the support plate 102 is provided with multiple first through holes, and the first through holes are fixedly provided with first bearings. The rollers 2 are fixedly connected to the transmission wheel 5 via a circular shaft, which is installed in the first bearings. The circular shaft is rotatably connected to the first through holes via the first bearings, thereby rotatably connecting the rollers 2 to the support plate 102.

[0066] The supporting frame 1 includes a plurality of reinforcing ribs 104 . One end of each reinforcing rib 104 is connected to one of the support plates 102 , and the other end thereof is connected to another of the support plates 102 , so as to improve the strength of the supporting frame 1 .

[0067] According to one embodiment of the present invention, Figure 2 As shown, the first driving mechanism includes a first motor 4, a second gear, a connecting rod and two transmission assemblies;

[0068] A transmission assembly is respectively provided on one side of the two roller assemblies that are away from each other;

[0069] The transmission assembly includes a transmission belt and a plurality of transmission wheels 5, and the plurality of transmission wheels 5 are driven by the transmission belt;

[0070] The axis of the connecting rod is parallel to the axis of the roller 2, one end of the connecting rod is connected to one of the rollers 2 in one of the roller assemblies, and the other end of the connecting rod is connected to one of the rollers 2 in the other roller assembly;

[0071] The transmission wheel 5 corresponds to the roller 2 one by one, and the roller 2 passes through one of the support plates 102 and is fixedly connected to the transmission wheel 5;

[0072] The output end of the first motor 4 is fixedly connected to a first gear, and the first gear is meshed with a second gear;

[0073] One end of one of the rollers 2 away from the transmission wheel 5 is fixedly connected to the second gear.

[0074] For the convenience of description, the two roller assemblies are referred to as the first roller assembly and the second roller assembly, and the two transmission assemblies are referred to as the first transmission assembly and the second transmission assembly. The first transmission assembly is provided on one side of the first roller assembly and is connected to the first roller assembly.

[0075] The second transmission assembly is arranged on one side of the second roller assembly and is connected to the second roller assembly.

[0076] The first motor 4 rotates, driving the first gear fixedly connected to its output end to rotate, the first gear drives the second gear meshing with it to rotate, and the second gear drives one of the rollers 2 in the first roller assembly to rotate. Since the roller 2 and the transmission wheel 5 are fixedly connected, the roller 2 is rotationally connected to the support plate 102, and the multiple transmission wheels 5 are driven by the conveyor belt, so that the remaining multiple rollers 2 in the first roller assembly can rotate around their respective axes;

[0077] Since one end of the connecting rod is connected to a roller 2 in the first roller assembly and the other end thereof is connected to a roller 2 in the second roller assembly, the roller 2 in the second roller assembly connected to the connecting rod can rotate synchronously around its own axis. Since the multiple transmission wheels 5 in the second transmission assembly are also connected through a conveyor belt, the multiple rollers 2 in the second roller assembly rotate around their respective axes, so that the multiple rollers 2 in the first roller assembly and the second roller assembly cooperate to drive the pallet to move along the first direction.

[0078] It should be noted that the axes of the multiple rollers 2 in the first roller assembly and the second roller assembly are parallel to each other. The axes of the rollers 2 are perpendicular to the first direction and parallel to the second direction.

[0079] Furthermore, in this embodiment, the first motor 4, the first gear, and the second gear form a drive assembly. The drive assembly can also be provided in two groups, with the drive assemblies corresponding one to one with the roller assemblies. Such a configuration does not deviate from the design concept of the present invention and therefore should fall within the scope of protection of the present invention.

[0080] Of course, in this embodiment, the transmission assembly can also be in other forms, such as a transmission chain and a plurality of transmission sprockets, which can also play a transmission role.

[0081] According to one embodiment of the present invention, Figure 2 and Figure 3 As shown, the second driving mechanism includes a second motor 6, two mounting plates 7, a driving gear 8, a driven gear 9, a chain 11, a plurality of connecting shafts 10 and a plurality of sprockets 12;

[0082] The connecting shaft 10, the sprocket 12 and the roller 3 all correspond to each other one by one;

[0083] A connecting shaft 10, a sprocket 12 and a roller 3 form a group. The axis of the connecting shaft 10, the axis of the sprocket 12 and the axis of the roller 3 in each group coincide with each other. The roller 3 in each group is fixedly sleeved on the connecting shaft 10, and the sprocket 12 is fixedly connected to one end of the connecting shaft 10. The two ends of the connecting shaft 10 are respectively rotatably connected to the two mounting plates 7.

[0084] Multiple sprockets 12 are driven by chains 11;

[0085] The output end of the second motor 6 passes through one of the mounting plates 7 and is connected to a driving gear 8. The driving gear 8 is meshed with a driven gear 9. The driven gear 9 is fixedly connected to one of the connecting shafts 10.

[0086] The two mounting plates 7 are fixedly connected to the supporting frame 1 .

[0087] It should be noted that the distance between the two roller assemblies is greater than the length of the roller 3 .

[0088] The second motor 6 rotates, driving the driving gear 8 fixedly connected to the output end to rotate, and the driving gear 8 drives the driven gear 9 meshing with it to rotate, thereby driving one of the connecting shafts 10 connected to the driven gear 9 to rotate. Since each connecting shaft 10 is rotatably connected to the mounting plate 7, each connecting shaft 10 is fixedly connected to a sprocket 12, and multiple sprockets 12 are driven by a chain 11. Therefore, the remaining multiple connecting shafts 10 can rotate around their respective axes, and thus the roller 3 on each connecting shaft 10 can rotate around the axis of the connecting shaft 10. The multiple rollers 3 cooperate to drive the tray to move in the second direction. The axis of the roller 3 is perpendicular to the second direction and parallel to the first direction.

[0089] Preferably, each mounting plate 7 can be fixedly connected to one of the reinforcing ribs 104 through a plurality of L-shaped sheet metal parts to secure it in place.

[0090] Of course, in this embodiment, each mounting plate 7 can also be connected to the base plate 101 via at least one electric telescopic rod. The electric telescopic rod moves synchronously, driving the electric telescopic rod to rise or fall at the same time. When the pallet moves in the first direction driven by the multiple rollers 2, the upper end surfaces of the multiple rollers 3 are lower than the upper end surfaces of the multiple rollers 2 driven by the electric telescopic rod, thereby preventing friction between the pallet and the rollers 3, and improving transportation stability. When the pallet needs to be transported to conveyor line 2 in the second direction, the electric telescopic rod drives the multiple rollers 3 to rise, lifting the pallet, so that the conveyor line is driven to move in the second direction to conveyor line 2 with the cooperation of the multiple rollers 3. This situation is applicable to the line change of two perpendicular conveyor lines 1 and 2 at different heights.

[0091] According to one embodiment of the present invention, Figure 4 As shown, a base frame is provided at the bottom of the carrier 1 , and the base frame includes a support plate 15 . A lifting mechanism for lifting the bottom plate 101 is provided between the support plate 15 and the bottom plate 101 .

[0092] The jacking mechanism provided enables the line changing device to be used for line changing between two conveyor lines 1 and 2 of different heights, thus having a wider scope of application and higher practicality.

[0093] Preferably, the lifting mechanism includes a plurality of bladder-type cylinders 14. Alternatively, the lifting mechanism uses ordinary cylinders as a power source, and linear bearings and guide posts as guides to achieve the lifting function. Such a mechanism does not deviate from the design concept of the present invention and therefore should fall within the scope of protection of the present invention.

[0094] The capsule cylinder 14 is preferably used because ordinary cylinders are equipped with linear bearings, and the linear bearings need to be lubricated, so the lubricating grease that seeps out of the linear bearings will pollute the surrounding environment. In addition, the debris and dust generated by the tray during operation falls into the linear bearings, causing the linear bearings to become stuck and fail. If cutting fluids, acids, alkalis and other substances are present in the outside world, the linear bearings will be corroded and their service life will be very short. The capsule cylinder 14 is used to achieve the lifting function of the jacking assembly, eliminating the linear bearings, guide columns and ordinary cylinders, so there is no need to use lubricating grease, and there is no pollution to the environment. And because the capsule cylinder 14 is a closed structure, there is no need to worry about debris, cutting fluids, acids, alkalis and other external substances causing structural failure, thus extending the service life.

[0095] According to an embodiment of the present invention, a protective cover 103 is fixedly connected to one side of the two support plates 102 away from each other, and the protective cover 103 is fixedly connected to the bottom plate 101;

[0096] The transmission assembly, the protective cover 103 and the support plate 102 correspond to each other one by one, and each transmission assembly is installed between the corresponding protective cover 103 and the support plate 102, that is, the conveyor belt and the plurality of transmission wheels 5 are installed between the support plate 102 and the protective cover 103;

[0097] The conveyor belt and the plurality of transmission wheels 5 in each transmission assembly are installed between the corresponding support plate 102 and the corresponding protective cover 103 , so that the conveyor belt and the plurality of transmission wheels 5 can be protected.

[0098] A baffle 13 is fixedly connected to one of the protective covers 103 , and the length direction of the baffle 13 is the same as the first direction, and is used to guide the tray to move only along the first direction;

[0099] The baffle 13 is located on the protective cover 103 away from the second conveyor line. The baffle 13 can guide the pallet so that the pallet can only move along the first direction, thereby improving its stability during transportation.

[0100] A laser transmitter is provided at one end of one of the protective covers 103, and a laser receiver is provided at one end of the other protective cover 103. The laser receiver and the laser transmitter are respectively installed at one end of the two protective covers 103 close to the conveyor line.

[0101] By setting up a laser receiver and a laser transmitter, it is possible to determine whether the pallet is transported to the right position (located directly above the carrier 1).

[0102] According to one embodiment of the present invention, the two support plates 102 are fixedly connected to a support member on one side close to each other, and the carrier frame 1 includes a top cover 105, the top cover 105 has a mounting table, and the support member is fixedly connected to the top cover 105, and the support member is used to support the top cover 105;

[0103] The top cover 105 is provided with a clearance area 107 for accommodating the plurality of rollers 3 and a clearance hole 106 for accommodating the plurality of rollers 2 .

[0104] The top cover 105 can protect the first motor 4 and the second motor 6 .

[0105] In the initial state, the laser receiver always receives the signal sent by the laser transmitter. At this time, the first driving mechanism does not work.

[0106] Specifically, when the pallet on conveyor line one is transported to the line changing device and passes through the laser transmitter, the laser receiver cannot receive the signal sent by the laser transmitter, and the first motor 4 in the first drive mechanism works. The first drive mechanism drives one of the rollers 2 in the first roller assembly to rotate around its own axis, and is transmitted through the first transmission assembly corresponding to the first roller assembly, so that the connecting rod and the remaining multiple rollers 2 in the first roller assembly rotate around their respective axes, and the connecting rod drives one of the rollers 2 in the second roller assembly to rotate, and then the second transmission assembly drives the remaining multiple rollers 2 in the second roller assembly to rotate around their respective axes, so that the pallet moves in the first direction. When the laser receiver receives the signal sent by the laser transmitter, it means that the pallet has moved into place, and the first motor 4 in the first drive mechanism stops working, and the second motor 6 in the second drive mechanism starts working. The second drive mechanism drives the multiple rollers 3 to rotate around their respective axes, so that the multiple rollers 3 cooperate to drive the pallet to move in the second direction, transporting the pallet to conveyor line two, and completing the line changing work.

[0107] Example 2:

[0108] A conveyor line, such as Figure 5 As shown, a line changing device is included, which also includes a conveying line 1 and a conveying line 2 which are perpendicular to each other. The line changing device is located at one end of the conveying line 1 close to the conveying line 2. When the conveying line 1 and the conveying line 2 are arranged perpendicularly, the first direction and the second direction are perpendicular.

[0109] The conveyor line also includes conveyor line three, which is symmetrically arranged on both sides of the carrier frame 1 with conveyor line one. When the pallet is transported from conveyor line one to conveyor line three, it can be selected according to actual conditions to start the first drive mechanism to drive multiple rollers 2 to rotate around their respective axes to transport the pallet to conveyor line three, or it can be selected to start the first drive mechanism to drive multiple rollers 2 to rotate around their respective axes until the pallet is directly above the mounting surface of the carrier frame 1, stop the first drive, and start the second drive mechanism so that multiple rollers 3 can drive the pallet to be transported along the second direction to conveyor line two.

[0110] Furthermore, the conveyor line can also include conveyor line four. At this time, after removing the baffle 13 on the line changing device, the four conveyor lines can be changed. Among them, the choice of transporting to conveyor line two or conveyor line four only requires changing the rotation direction of the second motor 6 in the second drive mechanism.
