[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0042] The flexible conveying unit disclosed in the utility model is as follows Figure 1 As shown, the flexible transport unit 10 includes a module base 111 , a linear motor module 112 disposed on the module base 111 , a load plate 113 connected to the linear motor module 112 , and a tray 114 disposed on the load plate 113 .
[0043] See also Figure 2 The module base 111 is generally in a "U"-shaped structure. The module base 111 can utilize the original production line body structure, or symmetrically set wing plates on the flat structure to form a groove similar to the "U"-shaped structure, which can also play the role of carrying the linear motor module 112, which has the same function as the module base 111. It can be seen that the specific structure of the module base 111 is not limited to this. Figure 2 Taking an example for illustration, the necessary structure of the module base 111 is described to support the linear motor module 112 .
[0044] Please see again Figure 2 The module base 111 includes a horizontal bottom plate 111a and a vertical baffle 111b arranged in parallel on the horizontal bottom plate 111a. The horizontal bottom plate 111a and the vertical baffle 111b extend freely in the y-axis direction, and the spacing between the vertical baffles 111b remains fixed. Through holes 111a1 are provided at intervals on the horizontal bottom plate 111a for sensors (such as Hall sensors) or cables to pass through. Platforms 111b1 are provided on the inner sides of adjacent vertical baffles 111b, which are used to carry the linear motor module 112 or the load plate 113. It can be seen that the platform 111b1 extends freely in the y-axis direction.
[0045] See also Figure 3 The linear motor module 112 includes a stator part 112a, a mover part 112b and a mover base 112c.
[0046] The linear motor module 112 is based on the principle of electromagnetic induction, does not require an intermediate conversion device, and can achieve high-speed linear feed and high motion accuracy and positioning accuracy. A linear motor is understood as a rotating motor that is cut in the radial direction and spread out to form a plane. According to the naming rules of rotating motors, the fixed part of the motor is called the stator, and the rotating part is called the rotor; for linear motors, the stator is also called the primary, and the rotor is called the secondary. The primary and secondary generate electromagnetic thrust under the interaction of the magnetic field, that is, the electromagnetic thrust is adjusted by controlling the current size, and precise positioning and high-speed movement can be achieved with sensors and control systems.
[0047] Please see again Figure 3 The stator part 112a includes a fixed plate 112a1 and a magnetic material 112a2. The fixed plate 1112a1 is fixedly arranged on the magnetic material 112a2 to play a protective role. The magnetic material 112a2 is a magnetic pole material, which can generate a magnetic field and can generate electromagnetic thrust in cooperation with the mover part 112b.
[0048] The mover part 112b is fixedly arranged on the mover base 112c. The front and rear sides of the mover part 112b are provided with fixing blocks 112b1 on the mover base 112c. The two fixing blocks 112b1 are used to fix the mover part 112b. A Hall sensor 112b2 is arranged on the fixing block 112b1. The Hall sensor 112b2 can be arranged on the same side of the fixing block 112b1. Figure 3 shown.
[0049] The mover base 112c is in a square cylindrical shape and freely extends in the y-axis direction. The mover part 112b is arranged on the mover base 112c at intervals. The length of the mover base 112c can be determined according to the length of the conveyor line. The mover base 112c is provided with a through hole II112c1 in the axial direction to reduce the overall mass. The cables and control lines of the mover part 112b can be arranged in the through hole II112c1.
[0050] The linear motor module 112 is assembled on the module base 111. Figure 4 and Figure 6 As shown, the mover part 112 b is arranged in the groove 1111 of the module base 111 ; the stator part 112 a is fixed to the bottom of the load plate 113 .
[0051] The load plate 113 can slide on the module base 111 along the y-axis direction. The bottom of the load plate 113 is fixedly connected to a slider 113a. The slider 113a can slide on a slide rail 113b set on the platform 111b1 of the module base 111. Figure 4 and Figure 6, slide rails 113b are arranged in parallel on the platform 111b1 of the module base 111, and sliders 113a are arranged along the y-axis direction on both sides of the bottom of the load plate 113, and the spacing between the sliders 113a on both sides matches the spacing between the slide rails 113b arranged on the platform 111b1. At this time, the stator part 112a is located between the sliders 113a on both sides, and in the vertical direction, it matches and does not contact with the mover part 112b.
[0052] It is known that the mover part 112b includes components such as coils and magnetic poles. The working principle of the mover part and the stator part belongs to the prior art and will not be repeated here. The idea of the present application is to achieve left and right precision adjustment and rapid movement positioning by controlling the relative movement of the stator part 112a and the mover part 112b of the linear motor module, thereby achieving a flexible conveying function.
[0053] A tray 114 is provided on top of the load plate 113 ( Figure 5 ), the tray 114 is fixed on the load plate 113 through a tray bracket 114a.
[0054] When the utility model is used, it is laid along the conveying line of the production line, and slide rails 113b are arranged in parallel on both sides along the length direction on the existing conveying line substrate, and the mover part 112b of the linear motor module 112 is fixedly arranged on the substrate (horizontal bottom plate 111a), and the mover part 112b is located between the two slide rails 113b. The mover part 112b is arranged at intervals along the length direction of the slide rail 113b, so that all the mover parts 112b are horizontally or smoothly transitioned in the length direction. The mover part 112b is limited to a fixed area by a fixed block I112b1, and a Hall sensor 112b2 is arranged on the fixed block I112b1. The Hall sensor 112b2 is used to detect and measure the position of the tray (stator part / load plate), and feed back the position information and related data to the control system. Sensors, such as photoelectric sensors, are also arranged at both ends of the slide rail 113b, which are used to detect and measure the position of the tray (stator part / load plate), and feed back the position information and related data to the control system.
[0055] The stator part 112a of the linear motor module 112 is fixed to the bottom of the load plate 113. At the same time, a slider 113a matching the slide rail 113b is provided at the bottom of the load plate 113, and the load plate 113 can slide along the slide rail 113b. A tray 114 is provided on the top of the load plate 113, and the tray 114 can be fixed to the top of the load plate 113 through a tray bracket 114a.
[0056] When the control system controls the current of the mover part 112b, the stator part 112a begins to accelerate in the magnetic field under the magnetic field force. By adjusting the current, the motion state of the stator part 112a can be controlled, such as accelerated motion, decelerated motion, and uniform motion. By changing the current direction, the stator part 112a can be controlled to move in the reverse direction, as well as reverse accelerated motion, reverse decelerated motion, and reverse uniform motion. With the help of sensors and control systems, precise positioning and high-speed motion can be achieved, meeting the flexible requirements of reciprocating motion, cyclic motion, and moving speed in the process.
[0057] The present application also proposes a flexible conveying system, such as Figure 7 As shown, it includes a flexible conveying unit 10, a lifting unit 20 and a belt conveying unit 30.
[0058] The flexible transport system includes at least one layer of transport lines, and the present application takes two layers of transport lines as an example for explanation. The structure of the flexible transport unit 10 is shown in the relevant description in the above embodiment.
[0059] The structure of the lifting unit 20 is as follows Figure 8 , Fig. 9 and Fig.10 As shown, a lifting unit 20 is vertically arranged at both ends of the conveyor line, and the lifting unit 20 includes a lifting motor 211, a guide rail 212, a moving device 213 and a drag chain 214. The lifting unit 20 is arranged vertically, and the lifting motor 211 is arranged on the guide rail 212. The output end of the lifting motor 211 is connected to the moving device 213. The moving device 213 slides vertically on the guide rail 212. The drag chain 214 is connected to the moving device 213 to play a positioning role. The moving device 213 is provided with a horizontal platform, and a module base 111 is fixedly arranged on the horizontal platform. The module base 111 is fixedly provided with a moving part 112b, combined with Figure 7 and Fig.10 When the lifting unit 20 moves to the upper position, the module base on the horizontal platform is at the same level as the module base on the conveying line. The stator part 112a of the linear motor module can be moved to the module base on the moving device 213, and then the product on the tray 114 is moved to the predetermined position. The lifting motor 211 is controlled to work, and the moving device 213 moves downward until it is flush with the lower conveying line, and the stator part 112a is controlled to move to the belt conveyor unit 30.
[0060] Both ends of the belt conveyor unit 30 can be connected to the lifting unit 20. For details, see Fig.11 , including a bracket 311, rollers 312 arranged at both ends of the bracket, and a belt 313 rolling on the rollers 312, and a driving motor 314 drives the belt conveying unit to work.
