Description

Technical Field

[0001] This utility model relates to the field of linear motor testing, specifically a linear motor loop test fixture. Background Technology

[0002] A sorting machine is an automated mechanical device used to quickly and efficiently classify and sort items according to preset rules (such as destination, size, weight, etc.). A linear motor is a device that directly converts electrical energy into linear motion, eliminating the need for intermediate conversion mechanisms such as gears and belts in traditional rotary motors. Linear motors play a crucial role in sorting machines, with their core function being to directly drive sorting carts or pallets to perform fast and precise linear motion, thereby achieving efficient and flexible item sorting.

[0003] In existing technology, sorting machines use linear motors to sort, convey, and transport items. After processing and production, linear motors undergo visual and performance testing. However, before being assembled and used in a sorting machine, linear motors may lack counterweight testing and inspection. Consequently, it is difficult for staff to effectively understand whether the linear motor can smoothly and normally sort and transport items when used in the sorting machine. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, linear motors are generally subjected to inspection processes such as appearance inspection and performance testing after processing and production. However, before being assembled and used in sorting machines, linear motors may lack counterweight testing and inspection, which makes it difficult for staff to understand whether the linear motor can smoothly and normally sort and transport items when used in sorting machines. This utility model proposes a linear motor loop test frame.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a linear motor loop test frame, including a frame body, an arc-shaped track and a linear track fixedly connected to one side of the frame body, two of each of the arc-shaped track and the linear track are provided, a rotating block is rotatably connected to the inner cavity of each of the two arc-shaped track and the linear track, multiple rotating blocks are provided, a connecting rod is rotatably connected to the inner cavity of each of the multiple rotating blocks, a chain plate is rotatably connected to the surface of each of the multiple connecting rods, a magnet is fixedly connected to one side of each of the multiple chain plates, a drive linear motor is fixedly connected to the top of the frame body, a fixing plate is fixedly connected to the bottom of the frame body, and a loading linear motor is fixedly connected to the top of the fixing plate.

[0006] Preferably, a main encoder is fixedly connected to the top of the frame body, and the main encoder is used to control the drive linear motor.

[0007] Preferably, a secondary encoder is fixedly connected to the top of the fixed plate, and the secondary encoder is used to control the loading linear motor.

[0008] Preferably, a tensioning connector and a track connector are provided on one side of the linear track, and a mounting plate is fixedly connected to the surface of one of the arc-shaped tracks.

[0009] Preferably, a reinforcing plate is provided at the bottom of the frame body, and a reinforcing block is provided at the top of the reinforcing plate.

[0010] Preferably, the bottom of the reinforcing block is slidably connected to the top of the reinforcing plate, and the top of the reinforcing block is fixedly connected to the bottom of the fixing plate.

[0011] Preferably, a protective cover is fixedly connected to one side of the mounting plate. Two protective covers are provided, and the two protective covers are symmetrically arranged with the center of the frame body as the central axis. The protective covers are used to protect the chain plate and the magnet block.

[0012] Preferably, each of the two protective covers is fixedly connected to one side with a connecting plate, which is fixedly connected to one side of the frame body by bolts, and the connecting plate is used to reinforce the protective cover.

[0013] Preferably, a frame connector is fixedly connected to one side of the arc-shaped track, and one side of the frame connector is fixedly connected to one side of the frame body.

[0014] Preferably, a reinforcing corner block is fixedly connected to one side of the frame body, and multiple reinforcing corner blocks are provided to reinforce the frame body.

[0015] The advantages of this utility model are:

[0016] This invention simulates the normal transport of a sorting machine by driving multiple chain plates and magnetic blocks through the operation of a linear motor. It also simulates the sorting machine's operation by applying reverse thrust and resistance to the chain plates and magnetic blocks through the operation of the loaded linear motor. Furthermore, the interaction between the chain plates, magnetic blocks, and the loaded linear motor allows for the testing and inspection of the driving linear motor. This solves the problem that while linear motors undergo visual and performance testing after processing and production, they may lack counterweight testing before assembly and use in a sorting machine. This hinders the ability of operators to effectively understand whether the linear motor can smoothly and normally sort and transport items when used in the sorting machine.

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a linear motor loop test fixture. (Refer to...) Figure 1 and Figure 4A linear motor loop test frame includes a frame body 1. An arc-shaped track 2 and a linear track 9 are fixedly connected to one side of the frame body 1. Two arc-shaped tracks 2 and two linear tracks 9 are provided. Rotating blocks 3 are rotatably connected to the inner cavity of each of the two arc-shaped tracks 2 and the linear track 9. Multiple rotating blocks 3 are provided. Connecting rods 4 are rotatably connected to the inner cavity of each of the multiple rotating blocks 3. Chain plates 5 are rotatably connected to the surface of each of the multiple connecting rods 4. Magnet blocks 6 are fixedly connected to one side of each of the multiple chain plates 5. A drive linear motor 8 is fixedly connected to the top of the frame body 1. A fixing plate 21 is fixedly connected to the bottom of the frame body 1. A loading linear motor 12 is fixedly connected to the top of the fixing plate 21.

[0026] The frame body 1 can install and fix the arc track 2 and the straight track 9. The arc track 2 can cooperate with the straight track 9 to connect multiple rotating blocks 3. The multiple rotating blocks 3 can be connected to the chain plates 5 through the connecting rods 4. The multiple chain plates 5 are connected to each other and rotate. When the multiple chain plates 5 are driven and moved, they can drive the multiple straight tracks 9 to rotate synchronously. The multiple straight tracks 9 can form a magnetic chain. When the drive linear motor 8 is operating, it can apply a magnetic thrust to the straight track 9, so that the chain plates 5 can be driven and moved through the magnet blocks 6, thereby simulating the long-term conveying and transmission of the sorting machine. The frame body 1 can fix and connect the loading linear motor 12 through the fixing plate 21. The loading linear motor 12 can apply a reverse thrust to the moving magnet blocks 6 and apply resistance to the operation of the drive linear motor 8, thereby simulating the state of the magnet blocks 6 and the chain plates 5 when the material is placed on them during transmission and movement. This makes it easier for the staff to observe, judge and record the operation of the drive linear motor 8.

[0027] Reference Figure 2 and Figure 3 The main encoder 7 is fixedly connected to the top of the frame body 1. The main encoder 7 is used to control the drive linear motor 8. The auxiliary encoder 13 is fixedly connected to the top of the fixing plate 21. The auxiliary encoder 13 is used to control the loading linear motor 12. The frame body 1 can connect to the main encoder 7. At the same time, the frame body 1 can also install and fix the auxiliary encoder 13 through the fixing plate 21. The main encoder 7 can be used to control the operation of the drive linear motor 8, and the auxiliary encoder 13 can control the loading linear motor 12. Thus, when the drive linear motor 8 is in operation, driving the chain plate 5 and the magnet block 6, the reverse thrust and resistance applied by the loading linear motor 12 can be smoothly and effectively adjusted. The main encoder 7 and the auxiliary encoder 13 can be selected according to different models according to the actual situation, such as Tamagawa-OIS38. The main encoder 7 and the auxiliary encoder 13 are existing technologies in this field, so they will not be described in detail here.

[0028] Reference Figure 1 and Figure 3 One side of the straight track 9 is provided with a tensioning connector 10 and a track connector 11. An mounting plate 19 is fixedly connected to the surface of one of the arc-shaped tracks 2. The tensioning connector 10 allows the multiple chain plates 5 to be adjusted after long-term use if they become loose. The track connector 11 facilitates the adjustment of the magnetic chain composed of multiple magnet blocks 6. At the same time, one of the arc-shaped tracks 2 can be used to install and connect the mounting plate 19. The tensioning connector 10 is similar in principle to the existing chain drive tensioner, while the track connector 11 is similar in principle to the existing high-speed rail track fastener. Therefore, the principles of the tensioning connector 10 and the track connector 11 will not be elaborated on here.

[0029] Reference Figure 2 and Figure 3 The frame body 1 has a reinforcing plate 14 at the bottom and a reinforcing block 15 at the top. The bottom of the reinforcing block 15 is slidably connected to the top of the reinforcing plate 14, and the top of the reinforcing block 15 is fixedly connected to the bottom of the fixing plate 21. The frame body 1 can connect the reinforcing block 15 through the reinforcing plate 14. The connection between the reinforcing block 15 and the fixing plate 21 allows the linear motor 8 to be fixed and reinforced when in use, through the connection between the reinforcing block 15 and the reinforcing plate 14, so that the linear motor 12 and the auxiliary encoder 13 have high stability when in use.

[0030] Reference Figure 1 and Figure 3 A protective cover 17 is fixedly connected to one side of the mounting plate 19. There are two protective covers 17, which are symmetrically arranged with the center of the frame body 1 as the central axis. The protective covers 17 are used to protect the chain plate 5 and the magnet block 6. The mounting plate 19 can connect the two protective covers 17. The two protective covers 17 are symmetrically arranged, which can effectively protect the chain plate 5 and the magnet block 6 during transmission and movement, so that the chain plate 5 and the magnet block 6 can move more smoothly during transmission and movement.

[0031] Reference Figure 2 and Figure 3Each of the two protective covers 17 has a connecting plate 18 fixedly connected to one side. The connecting plate 18 is fixedly connected to one side of the frame body 1 by bolts. The connecting plate 18 is used to reinforce the protective cover 17. A frame connector 16 is fixedly connected to one side of the arc track 2. One side of the frame connector 16 is fixedly connected to one side of the frame body 1. The setting of the connecting plate 18 can effectively connect the connecting plate 18 itself to the frame body 1 by bolts. The connecting plate 18 can strengthen and fix the protective cover 17 through its connection with the frame body 1 and the protective cover 17, so that the protective cover 17 has high stability and firmness when in use. The frame connector 16 can effectively strengthen the stability and firmness of the connection between the frame body 1 and the arc track 2, so that the arc track 2 has high stability when in use.

[0032] Reference Figure 2 and Figure 3 A reinforcing corner block 20 is fixedly connected to one side of the frame body 1. Multiple reinforcing corner blocks 20 are provided to reinforce the frame body 1. The reinforcing corner blocks 20 are triangular in shape, so that the multiple reinforcing corner blocks 20 can effectively use their connection with the frame body 1 to support and reinforce the frame body 1. This makes the frame body 1 more stable during use and less prone to shaking or instability due to the transmission and movement of the magnet block 6 and the chain plate 5.

[0033] Working principle: When using this device, the operator can connect the drive linear motor 8 to the frame body 1. When the drive linear motor 8 is operating, it can drive multiple chain plates 5 to move through the magnet block 6, thereby simulating the transmission and transportation state of the sorting machine. Then, the operator can start the loading linear motor 12. The operation of the loading linear motor 12 applies a reverse magnetic thrust to the magnet block 6, thereby applying resistance to the transmission of the magnet block 6 and the chain plate 5, thus simulating the sorting machine when the object is placed and then transported. After that, the operator can observe, test and record the operation of the drive linear motor 8 by observing the transmission speed and stability of the chain plate 5 and the magnet block 6, thereby determining whether the drive linear motor 8 meets the standards for use in the sorting machine.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
