[0008] According to some embodiments of the present invention, at least one pair of first infrared gratings are provided on both sides of the conveyor steel belt. The first infrared gratings are aligned with the surface of the conveyor steel belt, electrically connected to the host computer, and perpendicular to the conveying direction of the conveyor steel belt. The first infrared gratings are used to detect the length of the switch cabinet.

[0009] According to some embodiments of the present invention, a pair of second infrared gratings are provided at both ends of the conveyor steel belt. The second infrared gratings are parallel to the conveying direction of the conveyor steel belt, electrically connected to the host computer, and aligned with the surface of the conveyor steel belt.

[0010] According to some embodiments of the present invention, the teeth of the transmission gear and the teeth of the driven gear are covered with a buffer pad. When the second notch engages with the transmission gear or the driven gear, the buffer pad is located between the second notch and the transmission gear or the driven gear.

[0011] According to some embodiments of this utility model, it also includes: A photoelectric sensor is disposed at the end of the conveyor belt and aligned with the surface of the conveyor belt. The photoelectric sensor is used to detect the number of switch cabinets located on the conveyor belt.

[0013] According to some embodiments of the present invention, the conveying device includes a plurality of conveying steel belts, and for any two adjacent conveying steel belts, the beginning end of one conveying steel belt is connected to the end end of the other conveying steel belt.

[0014] This utility model embodiment includes: a plurality of first connecting blocks, each first connecting block having a first notch at both its front and rear ends, and a first through hole on each side of the first notch, all first connecting blocks being connected end-to-end; a plurality of second connecting blocks, each second connecting block having a parallel second through hole at its front and rear ends, the number of second connecting blocks being equal to the number of first connecting blocks, and the second connecting blocks being located between two connected first notches; and a plurality of connecting pins, the connecting pins being located inside the first through holes and the second through holes, the connecting pins being used to connect adjacent first connecting blocks and second connecting blocks, the first connecting blocks being hinged to the second connecting blocks via the connecting pins, and the number of connecting pins being at least twice the number of second connecting blocks.

[0015] Figure 1 This is a schematic diagram of the conveyor belt portion of a conveyor steel belt provided in one embodiment of the present invention; Figure 2 This is an overall structural diagram of the conveyor belt provided in another embodiment of the present invention. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. Terms such as "first," "objective," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0018] This utility model provides a conveyor belt and its conveying device. The conveyor belt includes: multiple first connecting blocks, each with a first notch at both its front and rear ends, and a first through hole on each side of the first notch, all of which are connected end-to-end; multiple second connecting blocks, each with a parallel second through hole at its front and rear ends, the number of which is equal to the number of the first connecting blocks, and each second connecting block is located between two connected first notches; and multiple connecting pins, located inside the first and second through holes, for connecting adjacent first and second connecting blocks, with the first connecting block hinged to the second connecting block via the connecting pins, and the number of connecting pins being at least twice the number of second connecting blocks. According to this embodiment, wear is less likely to occur between the switch cabinet and the conveyor belt, thus extending the lifespan of the conveyor belt. The hinged connection between the first and second connecting blocks via the connecting pins prevents the first and second connecting blocks from jamming during the conveyor belt's rotation.

[0019] Reference Figure 1 The conveyor belt 100 provided in this embodiment includes: Multiple first connecting blocks 10, each having a first notch 11 at both its front and rear ends, and a first through hole 12 on each side of the first notch 11, with all the first connecting blocks 10 connected end to end. Multiple second connecting blocks 20, each having a parallel second through hole 21 at its front and rear ends, the number of second connecting blocks 20 being equal to the number of first connecting blocks 10, and the second connecting blocks 20 being located between two connected first notches 11; Multiple connecting pins 30 are located inside the first through hole 12 and the second through hole 21. The connecting pins 30 are used to connect adjacent first connecting blocks 10 and second connecting blocks 20. The first connecting block 10 is hinged to the second connecting block 20 by the connecting pins 30. The number of connecting pins 30 is at least twice the number of second connecting blocks 20.

[0020] It should be noted that the switchgear 40 is conveyed by the conveyor belt 100. The conveyor belt 100 is made of metal, which is not easily worn by the switchgear 40. This can prevent the switchgear 40 placed on the conveyor belt 100 from damaging the conveyor belt, thereby extending the service life of the conveyor belt 100.

[0021] It should be noted that the conveyor belt 100 is installed in the execution workshops of each process of the switchgear 40. The switchgear 40 is transferred between different workshops through the conveyor belt 100, eliminating the need for manual intervention in the transfer steps of the switchgear 40 manufacturing process, thus greatly saving labor costs.

[0022] It should be noted that after the first connecting block 10 and the second connecting block 20 are connected by the connecting pin 30, there is a certain gap between the first connecting block 10 and the second connecting block 20 connected by the same connecting pin 30, so as to avoid collision or jamming during the hinge process. In the manufacturing process of the switch cabinet 40, there are multiple processes such as welding, grinding and air shower. After the grinding process is completed, there will be dust on the surface of the switch cabinet 40 and the surface of the conveyor steel belt 100. The dust falls off through the gap between the first connecting block 10 and the second connecting block 20, reducing the amount of dust adhering to the switch cabinet 40.

[0023] It should be noted that the connecting pins 30 are located in adjacent first through holes 12 and second through holes 21. For adjacent first connecting blocks 10 and second connecting blocks 20, a single connecting pin 30 can pass through the first through holes 12 and second through holes 21 located in the same straight line. Alternatively, two shorter connecting pins 30 can be used, located only inside one first through hole 12 and second through hole 21. By having two connecting pins 30 located in the first through holes 12 and second through holes 21 located in the same straight line, the first connecting block 10 and the second connecting block 20 can be hinged. Since a second connecting block 20 is provided with two parallel second through holes 21, the number of connecting pins 30 is at least twice that of the second through holes 21.

[0024] It should be noted that all the first connecting blocks 10 are connected end to end, and the second connecting block 20 is located in the first notch 11 of two adjacent first connecting blocks 10, that is, the second connecting block 20 is located in the notch formed by the two first notches 11. At this time, the second through holes 21 of the second connecting block 20 can be connected to the first through hole 12. The connecting pin 30 passes through the first through hole 12 and the second through hole 21, thereby realizing the hinge connection between the first connecting block 10 and the second connecting block 20. During the conveying process of the steel belt 100, the first connecting block 10 and the second connecting block 20 are initially located on the same plane, and there is no bend between the first connecting block 10 and the second connecting block 20. When the first connecting block 10 and the second connecting block 20 move to the end of the steel belt 100, the steel belt 100 needs to be rotated. At this time, the upper surface of the steel belt 100 that was conveying in the original direction becomes the lower surface of the steel belt 100 that was conveying in the opposite direction after rotation. During the rotation, the first connecting block 10 and the second connecting block 20 rotate along the connecting pin 30 to realize the conveying of the steel belt 100. Thus, during the conveying process of the steel belt 100, the situation where the first connecting block 10 and the second connecting block 20 get stuck, causing the steel belt 100 to be unable to be used normally, is avoided.

[0025] Additionally, in one embodiment, reference is made to Figure 2It also includes: a transmission gear, a driven gear and a motor. The conveyor belt 100 is used to convey the switch cabinet 40. The ends of the first connecting block 10 and the second connecting block 20 away from the switch cabinet 40 are provided with a plurality of second notches. The second notches can engage with the transmission gear and the driven gear. The motor is used to drive the transmission gear to rotate forward, reverse or stop.

[0026] It should be noted that the second notch meshes with the teeth of the drive gear and the driven gear. In order to reduce the vertical occupancy of the transmission steel belt 100 and keep the upper and lower surfaces of the transmission steel belt 100 parallel, the dimensions and parameters of the drive gear and the driven gear are the same.

[0027] It should be noted that the transmission gear is driven to rotate by the motor, and the transmission gear drives the first connecting block 10 and the second connecting block 20 to move along with the transmission gear through the second notch that meshes with it, thereby driving the driven gear to rotate through the first connecting block 10 and the second connecting block 20.

[0028] It should be noted that the conveyor belt 100 is a ring structure. The outer surface of the conveyor belt 100 facing upward is used to place the switch cabinet 40. The inner surface of the conveyor belt 100, that is, the side of the conveyor belt 100 away from the switch cabinet 40, is provided with multiple second notches. The drive gear and the driven gear are located inside the conveyor belt 100.

[0029] It should be noted that during the conveying process, the conveyor belt 100 conveys the switchgear 40 in the same direction. When a certain process needs to be performed on the switchgear 40, the transmission gear is stopped by the motor control, thereby stopping the conveyor belt 100 to operate the switchgear 40. After the process is completed, the transmission gear is rotated forward by the motor control to move the conveyor belt 100 to transport the switchgear 40.

[0030] Additionally, in one embodiment, reference is made to Figure 2 It also includes: a host computer, an emergency stop button 50 is provided at the beginning of the conveyor belt 100, the host computer is electrically connected to all the emergency stop buttons 50 and all the motors, the emergency stop buttons 50 can send electrical signals to the host computer, and the host computer is used to control the motor to stop based on the electrical signals.

[0031] It should be noted that the manufacturing process of switchgear 40 includes multiple processes. When a fault occurs in a switchgear 40 during the execution of a process, and the conveyor belt 100 drives the switchgear 40 to move according to the preset program, the emergency stop button 50 is manually triggered. The emergency stop button 50 generates an electrical signal and sends the electrical signal to the host computer. The host computer controls the motor to stop based on the electrical signal. The motor controls the conveyor belt 100 to stop by meshing with the second notch, so that the operator can perform maintenance operations.

[0032] Additionally, in one embodiment, reference is made to Figure 2At least one pair of first infrared gratings 60 are provided on both sides of the conveyor belt 100. The first infrared gratings 60 are aligned with the surface of the conveyor belt 100. The first infrared gratings 60 are electrically connected to the host computer. The first infrared gratings 60 are perpendicular to the conveying direction of the conveyor belt 100. The first infrared gratings 60 are used to detect the length of the switch cabinet 40.

[0033] It should be noted that the first infrared grating 60 is electrically connected to the host computer. The first infrared grating 60 includes a first incident grating and a first exiting grating. In the absence of any external obstruction, the first exiting grating emits infrared light to the first incident grating. When the switch cabinet 40 passes the first infrared grating 60, the first incident grating cannot receive the infrared light, that is, the first incident grating senses a change in the photoelectric signal state and sends an electrical signal to the host computer. When the switch cabinet 40 leaves the first infrared grating 60, the first incident grating receives the infrared light again, that is, the first incident grating senses a change in the photoelectric signal state and sends an electrical signal to the host computer. The host computer calculates the length of the switch cabinet 40 passing through the first infrared grating 60 based on the interval between the two received electrical signals and the rotation speed of the motor.

[0034] Additionally, in one embodiment, reference is made to Figure 2 A pair of second infrared gratings 70 are provided at both ends of the conveyor belt 100. The second infrared gratings 70 are parallel to the conveying direction of the conveyor belt 100. The second infrared gratings 70 are electrically connected to the host computer and are aligned with the surface of the conveyor belt 100.

[0035] It should be noted that the paired second infrared gratings 70 include a second emitting grating and a second incident grating. When there is no obstruction, the second emitting grating emits infrared light to the second incident grating. When the conveyor belt 100 is conveying the switch cabinet 40, the switch cabinet 40 is located between the second emitting grating and the second incident grating, and the second incident grating cannot receive the infrared light. When there is no switch cabinet 40 on the conveyor belt 100, the second incident grating receives the infrared light and generates a stop signal, which is sent to the host computer. The host computer controls the motor to stop, thereby controlling the conveyor belt to stop. The motor is restarted after the conveyor belt 100 continues to convey the switch cabinet 40, thus saving energy.

[0036] Additionally, in one embodiment, reference is made to Figure 2 The teeth of the drive gear and the driven gear are covered with a buffer pad. When the second notch meshes with the drive gear or the driven gear, the buffer pad is located between the second notch and the drive gear or the driven gear.

[0037] It should be noted that the transmission gear, driven gear, and conveyor belt 100 are all made of metal. After prolonged use, wear occurs on the transmission gear, driven gear, and the second notch, resulting in a gap between the transmission gear and the second notch. Regular replacement of the transmission gear, driven gear, and conveyor belt 100 is necessary. By incorporating a buffer pad, wear on the transmission gear, driven gear, and conveyor belt 100 is significantly reduced, thereby decreasing maintenance costs and time.

[0038] Additionally, in one embodiment, reference is made to Figure 2 It also includes: a photoelectric sensor 80, which is located at the end of the conveyor belt 100 and aligned with the surface of the conveyor belt 100. The photoelectric sensor 80 is used to detect the number of switch cabinets 40 located on the conveyor belt 100.

[0039] It should be noted that the photoelectric sensor 80 is electrically connected to the host computer. When the photoelectric sensor 80 acquires an image of the surface of the conveyor belt 100, and detects that the number of switch cabinets 40 located on the surface of the conveyor belt 100 is zero, the photoelectric sensor 80 generates a stop signal to the host computer. The host computer then controls the motor to stop based on the stop signal. Simultaneously, the host computer can adjust the motor speed based on the number of switch cabinets 40 returned by the photoelectric sensor 80, thereby adjusting the conveying speed of the conveyor belt 100.

[0040] It should be noted that the conveyor belt 100 transports the switchgear 40 from the beginning to the end. During the horizontal movement of the switchgear, the motor drives the conveyor belt 100 through the transmission gear and the driven gear. All the first connecting blocks 10 and all the second connecting blocks 20 of the conveyor belt have horizontal displacement, thereby realizing the horizontal movement of the switchgear 40 placed on the upper surface of the first connecting blocks and the second connecting blocks. After the switchgear 40 is fed onto the conveyor belt 100, it is positioned between the second infrared gratings 70. The second infrared gratings 70 detect that there is... Switch cabinet 40 is located on conveyor belt 100. Switch cabinet 40 moves horizontally. Visual photoelectric eye 80 detects that the number of switch cabinets 40 located on conveyor belt 100 increases by one. When switch cabinet 40 passes the first infrared grating 60, the host computer determines the length of switch cabinet 40 based on the time interval between the motor speed and the electrical signal returned by the first infrared grating 60. During the horizontal movement of switch cabinet 40, if an emergency occurs, the emergency stop button is triggered. The emergency stop button generates an electrical signal and sends it to the host computer. The host computer controls the motor to stop so as to control the conveyor belt to stop.

[0041] In one embodiment, reference is made to Figure 2 This utility model embodiment also provides a conveying device, including the conveyor steel belt 100 as described above.

[0042] It should be noted that the conveying device can be the conveying steel belt 100 itself, or other equipment that uses the conveying steel belt 100. This embodiment does not limit the specific type of conveying device, as long as the above-mentioned conveying steel belt 100 can be used.

[0043] Additionally, in one embodiment, reference is made to Figure 2 The conveying device includes multiple conveyor belts 100. For any two adjacent conveyor belts 100, the beginning of one conveyor belt 100 is connected to the end of the other conveyor belt 100.

[0044] It should be noted that multiple conveyor belts 100 are connected one after another in sequence, and each conveyor belt 100 can independently transport the switch cabinet 40.

[0045] It should be noted that the manufacturing process of switchgear 40 requires multiple processes, such as splicing cabinet panels and welding cabinet panels. Each process requires a different execution time. If switchgear 40 is transported by only one conveyor belt 100, after the process with the short execution time is completed, we have to wait for the process with the longest execution time to be completed before we can proceed to the next process of switchgear 40, which greatly reduces the production efficiency of switchgear 40.

[0046] It should be noted that by splicing multiple conveyor belts 100, the conveying direction and speed of each conveyor belt 100 can be independently controlled by a motor. For processes with short execution times, the conveying speed of the conveyor belts 100 can be slowed down, while for processes with long execution times, the conveying speed of the conveyor belts 100 can be accelerated. This prevents the conveyor belts 100 from running idle, which would lead to wasted production capacity, and also reduces the energy consumption of turning off the conveyor belts 100 and turning them back on after the switchgear is loaded. As a result, the production efficiency of the switchgear can be improved and energy costs can be saved.
