Description

Technical Field

[0001] This invention relates to the field of power supply equipment technology, and in particular to a circulating mobile power supply device and a power supply method for mobile equipment on a production line. Background Technology

[0002] Printer aging tests are typically conducted offline, which involves manually moving the printer off the main mobile production line and testing it with a fixed 220V AC power supply. This method is inefficient, time-consuming, and labor-intensive.

[0003] Therefore, there is an urgent need for a cyclic mobile power supply device and a power supply method for mobile devices on the production line, which can synchronously move and supply power to test equipment on the production line without removing the target test equipment from the production line, thus greatly improving test efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a circulating mobile power supply device and a power supply method for mobile equipment on a production line, aiming to solve the technical problem of low testing efficiency caused by the inability of equipment on the production line to be powered during testing.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a circulating mobile power supply device, comprising: a frame, an annular circulating moving mechanism disposed on the frame, and an annular sliding contact line fixedly disposed on the frame;

[0006] The annular sliding contact line is connected to the power supply and is located on the periphery of the moving path of the annular circulating moving mechanism; the moving end of the annular circulating moving mechanism is provided with several current collectors, and the brush on each current collector can slide and contact the annular sliding contact line to output a stable voltage for supplying power to the load.

[0007] As a further improvement to the above solution, the current collector is set at the moving end of the annular circulating moving mechanism via a slider assembly. Correspondingly, the frame is provided with an annular slide rail that matches the moving path of the annular circulating moving mechanism, and the slider assembly is matched and set on the annular slide rail.

[0008] Furthermore, the annular circulating moving mechanism, the annular slide rail, and the annular sliding contact line are arranged in parallel and spaced out from the inside to the outside.

[0009] As a further improvement to the above solution, the current collector is mounted on the slider assembly via a support frame; the support frame is provided with a socket for the target testing equipment moving on the production line to plug in, and the power terminal in the socket is connected to the corresponding current collector.

[0010] As a further improvement to the above solution, the annular circulating moving mechanism includes a drive motor and a drive sprocket disposed at one end of the frame, a driven sprocket disposed at the other end of the frame, and a transmission chain wound between the drive sprocket and the driven sprocket.

[0011] The drive motor is connected to the drive sprocket, and the plane of the transmission chain is parallel to the upper plane of the frame. The transmission chain constitutes the moving end of the annular circulating moving mechanism.

[0012] As a further improvement to the above solution, the slider assembly is mounted on the transmission chain via a connecting buckle.

[0013] As a further improvement to the above solution, the slider assembly includes a slider support plate and guide rollers disposed on the bottom surface of the slider support plate. The guide rollers are arranged in pairs at intervals and are slidably engaged on the annular slide rail.

[0014] The current collector is fixed at one end of the upper surface of the slider support plate, and the other end is connected to the connecting buckle through a screw, so that the current collector moves synchronously with the transmission chain.

[0015] As a further improvement to the above solution, the current collector is selected as the combined single-head current collector JDS1 type. Preferably, its brush contact pressure is 3.5N, the current can reach 40A, and the left, right and up and down offset is within + / -15mm.

[0016] As a further improvement to the above solution, the connecting buckle includes a first L-shaped connector and a second L-shaped connector. The horizontal side of the first L-shaped connector is connected to the transmission chain, and the vertical side of the first L-shaped connector is connected to the vertical side of the second L-shaped connector. The horizontal side of the second L-shaped connector is provided with a waist-shaped hole of a preset length for slidably connecting with the slider assembly.

[0017] As a further improvement to the above solution, a preset gap is provided between the lower surface of the horizontal side of the second L-shaped connector and the upper surface of the slider assembly;

[0018] The screw passes through the waist-shaped hole and is connected to the slider assembly via a threaded pair. The screw is provided with a locking nut, which is located within the preset gap.

[0019] As a further improvement to the above solution, the power supply includes an isolation transformer for connecting to a 380V AC power supply and outputting a 220V voltage.

[0020] In a second aspect, the present invention also provides a power supply method for mobile equipment on a production line, comprising a cyclic mobile power supply device as described in the first aspect, wherein the power supply method includes the following steps:

[0021] S1. The circulating mobile power supply device is set parallel to the inside of the production line, and its straight segment moves in the same direction as the production line.

[0022] S2. Adjust the moving speed of the circular moving mechanism to match the moving speed of the production line so that the two move synchronously;

[0023] S3. When the equipment on the production line moves to the first station of the mobile power supply device in this cycle, the power plug of the equipment is connected to the current collector at the corresponding position to obtain power.

[0024] S4. The production line and the circular moving mechanism move synchronously to move the equipment to the second station for testing; after the test is completed, the equipment is moved synchronously to the third station, and then the power plug of the equipment is unplugged. The equipment continues to move on the production line, and the corresponding current collector moves in a circular motion.

[0025] S5. Repeat steps S3 and S4 to sequentially power all devices on the production line.

[0026] Because the present invention adopts the above technical solutions, the beneficial effects of this application are as follows:

[0027] 1. The present invention provides a circulating mobile power supply device, comprising: a frame, a ring-shaped circulating moving mechanism disposed on the frame, and a ring-shaped sliding contact line fixedly disposed on the frame; the ring-shaped sliding contact line is connected to a power supply and disposed around the moving path of the ring-shaped circulating moving mechanism; the moving end of the ring-shaped circulating moving mechanism is provided with a plurality of current collectors, each of which has a brush that can slidably contact the ring-shaped sliding contact line and output a stable voltage for supplying power to the load; in the present invention, through a dynamic contact power supply structure, the device under test can be continuously powered within a preset moving speed range. Compared with the traditional method of moving the device under test away from the production line and powering it on at a fixed power source, the circulating mobile power supply device provided by the present invention does not require moving the device under test away from the production line. It only requires setting the circulating mobile power supply device parallel to the production line and making the ring-shaped circulating moving mechanism and the production line move synchronously to achieve synchronous moving power supply to the moving device under test on the production line, thereby greatly improving the testing efficiency;

[0028] Meanwhile, the ring layout adopted in this invention reduces the footprint of the power supply system, making it particularly suitable for the transformation of automated production lines with limited space. In addition, by increasing the number of collectors connected in parallel, a maximum power output of 120kW can be achieved, supporting parallel power supply of multiple voltage levels (48V-380V), thus giving this invention good compatibility and scalability. This invention has passed more than 72 hours of continuous operation testing, and key indicators such as voltage stability and temperature rise control all meet the requirements of national standards.

[0029] 2. The present invention also provides a power supply method for mobile devices on a production line. Through closed-loop speed matching control of the production line and the circulating mobile power supply device, the device under test on the production line can continuously receive power within a preset moving speed range. At the same time, the multi-station relay power supply mode realizes the device being tested with power throughout the entire process from the first station to the third station. Compared with the traditional test at a fixed power source after moving the device away from the production line, the test efficiency is greatly improved. Moreover, since it does not require moving the device away from the original production line, the labor intensity of the operators can also be reduced. Attached Figure Description

[0044] Example 1

[0045] See Figures 1-6 The present invention provides a circulating mobile power supply device, comprising: a frame 1, an annular circulating moving mechanism 2 disposed on the frame 1, and an annular sliding contact line 3 fixedly disposed on the frame 1;

[0046] The annular sliding contact line 3 is connected to the power supply and is located on the periphery of the moving path of the annular circulating moving mechanism 2; the moving end of the annular circulating moving mechanism 2 is provided with a plurality of current collectors 4, and the brush 41 on each current collector 4 can slide and contact the annular sliding contact line 3 and output a stable voltage for supplying power to the load.

[0047] Specifically, in this embodiment, the frame 1 includes a support platform and a plurality of legs disposed on the bottom surface of the support platform, and the annular sliding contact line 3 is disposed on the support platform via an annular frame;

[0048] The current collector 4 is the main component for collecting power. In this embodiment, it adopts an elastic structure, including two brushes 41. Both brushes 41 are in contact with the sliding contact line. The elastic structure allows for good contact with the sliding contact line in both straight and arc sections, so that each current collector 4 can obtain a stable output voltage to supply power to the corresponding load.

[0049] The sliding contact line is made of C-type high-protection IP-rated copper core material with a cross-sectional area of ​​10 square millimeters, which can adapt to large contact current. Correspondingly, the current collector 4 is a combined single-head current collector 4JDS1 type, with a brush 41 contact pressure of 3.5N, a current of up to 40A, and a left / right and up / down offset within + / -15mm. This can effectively ensure that the current collector 4 and the sliding contact line have continuous and good contact, avoiding the problems of no voltage output and instantaneous arcing.

[0050] In this invention, the device under test 11 is continuously powered within a preset moving speed range by a dynamic contact power supply structure. Compared with the traditional method of moving the device under test 11 away from the production line 10 and powering it on at a fixed power source, the cyclic moving power supply device provided by this invention does not require moving the device under test 11 away from the production line 10. It only needs to be set parallel to the production line 10 and make the ring cyclic moving mechanism 2 and the production line 10 move synchronously to achieve synchronous moving power supply to the moving device under test 11 on the production line 10, thereby greatly improving the testing efficiency.

[0051] Meanwhile, the ring layout adopted in this invention reduces the footprint of the power supply system, making it particularly suitable for the transformation of automated production lines 10 with limited space. In addition, by increasing the number of current collectors 4 in parallel, a maximum power output of 120kW can be achieved, supporting parallel power supply of multiple voltage levels (48V-380V), thus giving this invention good compatibility and scalability. This invention has passed more than 72 hours of continuous operation testing, and key indicators such as voltage stability and temperature rise control all meet the requirements of national standards.

[0052] In a preferred embodiment, the current collector 4 is disposed at the moving end of the annular circulating moving mechanism 2 via a slider assembly 5. Correspondingly, the frame 1 is provided with an annular slide rail 6 that matches the moving path of the annular circulating moving mechanism 2, and the slider assembly 5 is disposed on the annular slide rail 6.

[0053] Furthermore, the annular circulating moving mechanism 2, the annular slide rail 6, and the annular sliding contact line 3 are arranged in parallel and spaced apart from the inside out.

[0054] The arrangement of the annular slide rail 6 and the slider assembly 5 provides effective guidance for the movement of the current collector 4, so as to ensure that the brush 41 on the current collector 4 can effectively contact the corresponding sliding contact line, thereby ensuring a stable output voltage. In this embodiment, the slider assembly 5 includes a slider support plate 51 and guide rollers 52 disposed on the bottom surface of the slider support plate 51. The guide rollers 52 are arranged in pairs at intervals and are slidably engaged on the annular slide rail 6.

[0055] The annular slide rail 6 includes an annular support and a guide plate disposed on the upper surface of the annular support, and the annular support extends from both sides of the guide plate to form guide wings; the pair of guide rollers 52 are slidably disposed on the guide wings;

[0056] To further ensure that the current collector 4 can move smoothly without jamming, the annular slide rail 6 is processed by laser cutting to improve the flatness and cut surface finish of the annular slide rail 6.

[0057] In a preferred embodiment, the current collector 4 is mounted on the slider assembly 5 via a support frame 7; the support frame 7 is provided with a socket 9 for the target testing equipment 11 that moves on the production line 10 to be plugged in, and the power terminal in the socket 9 is connected to the corresponding current collector 4; the socket 9 facilitates the plugging and unplugging of the target testing equipment 11, making the operation more convenient and improving the testing efficiency.

[0058] As a preferred embodiment, see Figure 1 and Figure 2 The annular circulating moving mechanism 2 includes a drive motor 21 and a drive sprocket 22 disposed at one end of the frame 1, a driven sprocket 23 disposed at the other end of the frame 1, and a transmission chain 24 wound between the drive sprocket 22 and the driven sprocket 23.

[0059] The drive motor 21 is driven and connected to the drive sprocket 22, and the plane of the transmission chain 24 is parallel to the upper plane of the frame 1. The transmission chain 24 constitutes the moving end of the annular circulating moving mechanism 2. Specifically, in this embodiment, the annular circulating moving mechanism 2 is set on the support platform. A first bushing is provided at one end of the support platform. The drive shaft of the drive sprocket 22 passes through the first bushing and extends out of the first bushing, and its extended end is connected to the drive motor 21. The drive sprocket 22 is located above the upper surface of the support platform, and the drive motor 21 is located below the bottom surface of the support platform. Correspondingly, a second bushing is matched at the other end of the support platform. The driven shaft of the driven sprocket 23 passes through the second bushing. The driven sprocket 23 is located above the upper surface of the support platform. The transmission chain 24 is wound between the drive sprocket 22 and the driven sprocket 23 to form a closed loop. When the drive motor 21 is started, the drive sprocket 22 is driven to rotate, and the transmission chain 24 moves cyclically, thereby driving the current collector 4 to move cyclically.

[0060] Specifically, the slider assembly 5 is mounted on the transmission chain 24 via a connecting buckle 8; one end of the upper surface of the slider support plate 51 is fixed with the current collector 4, and the other end is connected to the connecting buckle 8 via a screw 85, so that the current collector 4 moves synchronously with the transmission chain 24.

[0061] In a preferred embodiment, the connecting buckle 8 includes a first L-shaped connector 81 and a second L-shaped connector 82. The horizontal side of the first L-shaped connector 81 is connected to the transmission chain 24, and the vertical side of the first L-shaped connector 81 is connected to the vertical side of the second L-shaped connector 82. The horizontal side of the second L-shaped connector 82 is provided with a waist-shaped hole 83 for adjustable connection with the slider assembly 5. The combination of the two L-shaped connectors allows the connecting buckle 8 to be finely adjusted in both the vertical and horizontal directions, further ensuring that the brush 41 on the current collector 4 can effectively contact the sliding contact line to stabilize the output voltage.

[0062] In this embodiment, see Figure 3 and Figure 4 A preset gap 84 is provided between the lower surface of the horizontal side of the second L-shaped connector 82 and the upper surface of the slider assembly 5;

[0063] The screw 85 passes through the oblong hole 83 and is connected to the slider assembly 5 by a threaded pair, and the screw 85 is provided with a locking nut 86, which is located within the preset gap 84; preferably, the screw 85 is a high-strength screw of grade 12.9;

[0064] In this embodiment, the slider assembly 5 is mounted on the transmission chain 24 via a connecting buckle 8. In the arc segment of the annular slide rail 6, due to the continuous change in the driving force direction of the transmission chain 24, the slider assembly 5 and the connecting buckle 8 experience continuous relative movement. Therefore, the oblong hole 83 on the connecting buckle 8 can adapt to the positional changes of the slider assembly 5. A preset gap 84 is reserved between the connecting buckle 8 and the slider assembly 5, and the screw 85 is fixedly mounted on the slider assembly 5 within the preset gap 84 by a locking nut 86. This ensures a stable connection of the screw 85, eliminates loosening, and the preset length oblong hole 83 allows the current collector 4, when moving to the arc segment, to slide within the oblong hole 83, thus preventing jamming and ensuring continuous voltage output from the current collector 4.

[0065] In a preferred embodiment, the power supply includes an isolation transformer for connecting to a 380V AC power supply and outputting a 220V voltage;

[0066] The device is powered by 380V AC and outputs 220V with a power of 5KW through an isolation transformer. This isolates the internal components of the device 11 from the mains power to prevent electric shock from touching the internal components. The 220V output of the isolation transformer is connected to the sliding contact line. The current collector 4 fixed on the slider assembly 5 is always in contact with the sliding contact line during operation to obtain 220V power and supply power to the load.

[0067] Example 2

[0068] The present invention also provides a power supply method for mobile equipment on a production line, including a cyclic mobile power supply device as described in Embodiment 1, wherein the power supply method includes the following steps:

[0069] S1. The circulating mobile power supply device is arranged parallel to the inside of the production line 10, and its straight-line movement direction is consistent with the movement direction of the production line 10; in this embodiment, the laser printer production aging test production line 10 is used as an example for explanation, see [link to documentation]. Figure 6 Multiple laser printers are placed on production line 10 and move along with production line 10 at a preset speed;

[0070] S2. Adjust the moving speed of the circular moving mechanism 2 to match the moving speed of the production line 10 so that the two move synchronously.

[0071] S3. When the equipment 11 (laser printer) on the production line 10 moves to the first station of the current cycle mobile power supply device, the power plug of the equipment 11 is connected to the current collector 4 at the corresponding position to obtain power.

[0072] S4. The production line 10 and the circular circulating moving mechanism 2 move synchronously to move the equipment 11 (laser printer) to the second station for testing; after the test is completed, the equipment 11 is moved synchronously to the third station, and then the power plug of the equipment 11 is unplugged. The equipment 11 continues to move on the production line 10, and the corresponding current collector 4 moves in a cycle.

[0073] S5. Repeat steps S3 and S4 to sequentially power supply and test all devices 11 on the production line.

[0074] The power supply method provided by this invention enables the device under test 11 on the production line 10 to continuously receive power within a preset moving speed range through closed-loop speed matching control of the production line 10 and the circulating mobile power supply device. At the same time, the multi-station relay power supply mode enables the device 11 to be tested with power throughout the entire process from the first station to the third station. Compared with the traditional test at a fixed power source after moving the production line 10, the test efficiency is greatly improved. Moreover, since it does not require moving the original production line 10, the labor intensity of the operators can also be reduced.

[0075] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
