Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and specifically to a safe mobile power supply device for a conveyor. Background Technology

[0002] In some automated production lines, it is necessary to maintain continuous power to the workpieces. One method involves using current collectors (FCAs) and copper strips on the bottom of the fixture plate for power supply. The FCAs are powered by the output of an isolation transformer. Due to the characteristics of the isolation transformer, contacting a single phase of the FCAs alone does not pose a risk of electric shock. However, in extreme cases, simultaneous contact with two phases or one phase and the neutral wire can occur, leading to a risk of electric shock. To address this issue, existing enterprises typically employ two power supply methods: one is to use a contactor and inductive switch to individually power each FCA group when the fixture plate arrives; the other is to mount each FCA group on a cylinder assembly and use an inductive switch to individually raise and contact the fixture plate when it arrives. While these two methods can reduce the risk of electric shock to some extent, they involve more electrical control wiring, more electrical control components, and higher costs. Furthermore, after prolonged and frequent operation, the contactor contacts may stick together, leading to malfunctions. Utility Model Content

The rotation of the gear drives the rack to rise, thereby causing the collector-emitter assembly to protrude from the surface of the cover.

[0006] Optionally, the support base is provided with limiting grooves on both sides, and the two ends of the movable base are respectively inserted into the two limiting grooves.

[0007] Optionally, the support base has limiting protrusions on both sides, and the smooth surface of the rack abuts against the limiting protrusions.

When the tooling plate passes the power supply device, it first touches the roller and drives the roller to rotate. The rotation of the roller drives the rotating shaft and gear to rotate. The rotation of the gear drives the rack to move upward, thereby driving the movable seat to move upward, driving the current collector component to protrude from the surface of the cover plate and contact the conductive copper strip at the bottom of the tooling plate. The current collector component is electrically connected to an external isolation transformer to transmit current to the tooling plate and the workpiece on the tooling plate.

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] The following is combined with Figures 1 to 9This invention describes a safe mobile power supply device for a conveyor line.

[0032] like Figures 1 to 9 As shown, this utility model provides a safe mobile power supply device for a conveyor line, including a base 1, a support 2, a cover plate 3, a rotating shaft 4, rollers 5, gears 6, racks 7, a movable seat 8, and a collector-emitter assembly 9. The support 2 is located on the base 1, the cover plate 3 is located on the upper side of the support 2, the rotating shaft 4 is rotatably connected to the support 2, the rollers 5 are located at both ends of the rotating shaft 4, the gears 6 are located on the gears 6, the rack 7 meshes with the gears 6, the movable seat 8 is connected to the rack 7, and the collector-emitter assembly 9 is located on the movable seat 8. The rotation of the gears 6 drives the rack 7 to rise, thereby causing the collector-emitter assembly 9 to protrude from the surface of the cover plate 3.

[0033] In some embodiments, the support base 2 is provided with limiting grooves on both sides, and the two ends of the movable base 8 are respectively inserted into the two limiting grooves. The two limiting grooves can restrict the movement path of the movable base 8, ensuring that the movable base 8 can only move up and down, and the movement process is more stable.

[0034] In some embodiments, the support base 2 is provided with limiting protrusions 201 on both sides, and the smooth surface of the rack 7 abuts against the limiting protrusions 201. The limiting protrusions 201 can restrict the movement path of the rack 7, ensuring that the rack 7 and the movable base 8 can only move up and down, and the movement process is more stable.

[0035] In some embodiments, the current collector assembly 9 includes a current collector mounting base 901, a current collector support copper column 902, a current collector spring 903, a conductive wheel 904, and a conductive terminal 905. The current collector mounting base 901 is disposed on the movable base 8. The current collector support copper column 902 passes through the current collector mounting base 901 and can move in the vertical direction. The current collector spring 903 is sleeved on the current collector support copper column 902. One end of the current collector spring 903 is connected to the current collector support copper column 902, and the other end of the current collector spring 903 is connected to the current collector mounting base 901. The conductive wheel 904 is rotatably connected to the top end of the current collector support copper column 902. The conductive terminal 905 is connected to the bottom end of the current collector support copper column 902. Both the cover plate 3 and the support base 2 are provided with clearance holes for avoiding the conductive wheel 904.

[0036] Specifically, the conductive wheel 904 is made of copper. When the fixture plate 14 passes the power supply device, it will first touch the roller 5 and drive the roller 5 to rotate. The rotation of the roller 5 drives the rotating shaft 4 and the gear 6 to rotate. The rotation of the gear 6 will drive the rack 7 to move upward, thereby driving the movable seat 8 to move upward, and then driving the collector mounting seat 901 to move upward, and then driving the conductive wheel 904 to move upward. After passing through the clearance hole, the conductive wheel 904 contacts the conductive copper strip 15 at the bottom of the fixture plate 14. The conductive terminal 905 is electrically connected to the external isolation transformer. The current is transmitted to the fixture plate 14 and the workpiece on the fixture plate 14 through the collector support copper column 902 and the conductive wheel 904. Compared with the existing power supply method, this power supply method is simpler, has fewer electrical control components, and is lower in cost.

[0037] In some embodiments, the inside of the current collector mounting base 901 is provided with a clearance channel for the current collector support copper column 902 to pass through. The inner wall of the clearance channel is provided with a spring abutment. The current collector support copper column 902 has a T-shaped structure. The upper end of the current collector spring 903 abuts against the current collector support copper column 902, and the lower end of the current collector spring 903 abuts against the spring abutment. By setting the current collector spring 903, the current collector support copper column 902 can maintain an upward movement trend, thereby ensuring that the conductive wheel 904 can maintain contact with the conductive copper strip 15 at the bottom of the tooling plate 14, resulting in better power supply effect.

[0038] In some embodiments, the power supply device further includes a friction washer assembly 10, which includes a retaining ring 1001, a thin flat washer 1002, a plastic washer 1003, and a corrugated elastic washer 1004. The friction washer assembly 10 is provided at one end of the roller 5 away from the gear 6, and the thin flat washer 1002, the plastic washer 1003, and the corrugated elastic washer 1004 are provided between the roller 5 and the gear 6.

[0039] Specifically, the retaining ring 1001 serves a fixing function, ensuring that the roller 5 can be installed on the rotating shaft 4. The friction washer assembly 10 is mainly used to provide friction for the roller 5. When the tooling plate 14 initially contacts the roller 5, the friction between the tooling plate 14 and the roller 5 is small. The roller 5 can drive the rotating shaft 4 and the gear 6 to rotate, thereby driving the rack 7, the movable seat 8, and the current collector assembly 9 to move upward. When the tooling plate 14 is completely above the roller 5, the friction between the tooling plate 14 and the roller 5 is large and greater than the friction between the friction washer assembly 10 and the roller 5. At this time, the friction washer assembly 10 can no longer restrict the rotation of the roller 5, resulting in slippage. That is, the roller 5 can continue to rotate, but the rotating shaft 4 and the gear 6 do not rotate. While ensuring that the transportation of the tooling plate 14 is not affected, the stability of the gear 6 can also be maintained, that is, the contact between the current collector assembly 9 and the conductive copper strip 15 at the bottom of the tooling plate 14 is maintained, resulting in a more stable power supply effect.

[0040] In some embodiments, the roller 5 includes a flexible outer ring 501 and a rigid inner ring 502. The rigid inner ring 502 is connected to the rotating shaft 4. The flexible outer ring 501 is fitted onto the rigid inner ring 502, which can reduce damage to the tooling plate 14.

[0041] In some embodiments, the base 1 includes a first base plate 101, a second base plate 102, a screw 103, and a base plate spring 104. The screw 103 passes through the first base plate 101 and the second base plate 102 from top to bottom. The threaded portion of the screw 103 is connected to the second base plate 102. The first base plate 101 is slidably connected to the smooth portion of the screw 103. One end of the base plate spring 104 abuts against the first base plate 101, and the other end of the base plate spring 104 abuts against the second base plate 102. The support base 2 is disposed on the first base plate 101. By providing the base plate spring 104, a buffer effect can be provided for the entire device, resulting in better transportation performance.

[0042] In some embodiments, the safety moving power supply device for the conveyor line further includes a frame 11, a drive assembly 12, a conveying assembly 13, a tooling plate 14, and the aforementioned power supply device. The drive assembly 12 is disposed on the frame 11 and connected to the conveying assembly 13. Multiple power supply devices are arranged in a row on the frame 11. The conveying assembly 13 is used to convey the tooling plate 14. The bottom of the tooling plate 14 is provided with a conductive copper strip 15. When the current collector assembly 9 protrudes from the surface of the cover plate 3, it can contact and conduct electricity with the conductive copper strip 15.

[0043] In the safe moving power supply device for the conveyor line provided by this utility model, the conveying component 13 conveys the tooling plate 14 loaded with workpieces along the first direction. When the tooling plate 14 passes the power supply device, it will first touch the roller 5 and drive the roller 5 to rotate. The rotation of the roller 5 drives the rotating shaft 4 and the gear 6 to rotate. The rotation of the gear 6 will drive the rack 7 to move upward, thereby driving the movable seat 8 to move upward, driving the current collector component 9 to protrude from the surface of the cover plate 3 and contact the conductive copper strip 15 at the bottom of the tooling plate 14. The current collector component 9 is electrically connected to the external isolation transformer and transmits current to the tooling plate 14 and the workpiece on the tooling plate 14. The tooling plate 14 moves along the first direction and will always be in contact with each power supply device, thereby realizing continuous power supply to the workpiece. Compared with the existing power supply method, the overall structure of the power supply device of this utility model is simpler, with fewer control wirings, requiring only simple wire connections. It has fewer electrical control components, lower cost, longer service life, and better protection.

[0044] In some embodiments, a blocking component 16 is also included. The blocking component 16 is disposed on the frame 11 and is used to restrict the movement of the tooling plate 14 to facilitate the processing of the workpiece on the tooling plate 14.

[0045] In some embodiments, the drive assembly 12 includes a motor and a drive shaft, and the conveying assembly 13 includes a conveying strip and a conveying wheel. The motor transmits power to the conveying chain through the drive shaft, thereby driving the conveying wheel to rotate, and thus completing the conveying of the tooling plate 14.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
