Description

Technical Field

[0001] This patent relates to the field of transportation equipment, and in particular to a lifting transportation device and conveying system. Background Technology

[0002] Solar cell cassettes are a common transport vehicle in the photovoltaic cell production process. Each cassette, along with the solar cells it carries, can weigh over 4 kilograms. Existing solar cell cassettes are typically equipped with a scissor arm mechanism for loading and unloading. This mechanism uses a hydraulic cylinder or motor to adjust the angle between the scissor arms, thereby raising and lowering the cassette for loading and unloading.

[0003] However, in traditional scissor lift mechanisms, the required output force during ascent and descent is inversely proportional to the angle α between the scissor lift and the fork. That is, the smaller the angle α, the greater the required output force. The formula for the output force is F = ((G / 2) / tanα) / η, where F is the driving output force, G is the overall load-bearing capacity of the fork, and η is the lead screw conversion efficiency. Therefore, as the fork lift descends, the smaller the angle α approaches 0, the greater the driving output force F approaches infinity. In practical applications, the angle between the fork and the ground needs to be around 5°. If the lead screw model and motor output power are selected directly according to the formula, the motor output power needs to be about three times that of the 5° angle to meet the load and cycle time requirements. This necessitates a corresponding increase in the diameter of the components, leading to a sharp increase in cost and space requirements.

[0004] In view of this, there is an urgent need in the market for a new type of lifting and transporting device to solve the problems of scissor lift lifting and transporting devices in related technologies, such as the need for high-power drives, relatively large component sizes, and relatively high configuration costs.

[0048] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0049] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a lifting and transporting device, which includes a platform 1, a base 2, a scissor arm mechanism 3, and an auxiliary lifting mechanism 4; the base 2 is spaced below the platform 1 and is movably supported and connected to the platform 1 by the scissor arm mechanism 3; the auxiliary lifting mechanism 4 is disposed in the base 2 and has a lifting member 43 that can move towards the platform 1; wherein, the platform 1 can move up and down under the drive of the scissor arm mechanism 3, and the auxiliary lifting mechanism 4 can move up and down together with the scissor arm mechanism 3 to push the platform 1.

[0051] The lifting and transporting device provided in this embodiment can be specifically, but is not limited to, lifting and transporting battery cell boxes. The usage process will be described using this as an example.

[0052] In practical use, the scissor arms in the scissor arm mechanism 3 are in their shortest retracted state, and the angle between the scissor arms and the platform 1 is at its smallest (approximately 5°). When the platform 1 receives the battery cell cassette from the upstream conveyor mechanism, the scissor arms in the scissor arm mechanism 3 can extend accordingly, lifting the platform 1 away from the base 2. At the same time, the auxiliary lifting mechanism 4 can also simultaneously push against the platform 1 to move upward, sharing the driving force of the initial upward movement of the platform 1. This significantly reduces the maximum output power of the scissor arm mechanism 3 during the initial lifting, thus greatly reducing the required rated drive power of the scissor arm mechanism 3, correspondingly reducing the size of the selected accessories, and lowering the configuration cost.

[0053] Of course, the auxiliary lifting mechanism 4 can participate in the lifting throughout the entire upward stroke of the platform 1; or it can participate in the lifting only in the first half or the first third of the upward stroke of the platform 1. When the angle between the scissor arm in the scissor arm mechanism 3 and the platform 1 is greater than a predetermined value, the auxiliary lifting mechanism 4 can stop participating in the lifting. The specific lifting stroke of the auxiliary lifting mechanism 4 can be flexibly adjusted according to the actual usage scenario and the actual lifting load.

[0054] In summary, the lifting and transporting device provided in this embodiment can lift the platform 1 together with the auxiliary lifting mechanism 4 and the scissor arm mechanism 3 during the initial stroke of the platform 1's upward movement. The auxiliary lifting mechanism 4 can effectively share the driving force of the platform 1 during the initial rise, thereby significantly reducing the maximum output power of the scissor arm mechanism 3 during the initial lift. As a result, the rated driving power required by the scissor arm mechanism 3 is reduced, the size of the corresponding parts can be reduced accordingly, and the configuration cost is effectively reduced.

[0055] In one embodiment, the auxiliary lifting mechanism 4 further includes a drive cylinder 41 and a cylinder piston 42; the drive cylinder 41 is fixedly disposed in the base 2; the cylinder piston 42 is movably disposed in the drive cylinder 41 in the vertical direction, and can extend or retract in the drive cylinder 41 under the drive of the drive cylinder 41; wherein, the lifting member 43 is disposed at the top of the cylinder piston 42, and is used to abut against the platform 1 for support.

[0056] Specifically, in combination Figure 2 and Figure 3 In further detail, the auxiliary lifting mechanism 4 is specifically configured to include a drive cylinder 41, a cylinder piston 42, and a lifting member 43. In the initial stage of the upward movement of the platform 1, the drive cylinder 41 can extend the drive cylinder piston 42 vertically upward by applying pressure, and the lifting member 43 at the top of the cylinder piston 42 can correspondingly abut and support the platform 1. As the cylinder piston 42 continues to extend upward, the actual output driving force of the drive cylinder 41 can gradually decrease until the cylinder piston 42 reaches its maximum extension stroke. At this time, the actual lifting power of the auxiliary lifting mechanism 4 drops to zero, and the scissor arm mechanism 3 can independently lift and support the platform 1.

[0057] The specific configuration of the aforementioned auxiliary lifting mechanism 4 has the beneficial effects of simple structure, ability to output gradually decreasing auxiliary lifting force, and smoother overall lifting stroke of the platform 1.

[0058] Of course, the auxiliary lifting mechanism 4 mentioned above can also be configured in other ways, such as in the form of "hydraulic cylinder + hydraulic piston" or "compression spring + lifting rod", which can provide an auxiliary lifting effect in the initial stage of the upward movement of the platform 1.

[0059] In one embodiment, multiple auxiliary lifting mechanisms 4 are provided in the base 2; and the multiple auxiliary lifting mechanisms 4 can synchronously rise and move against the platform 1.

[0060] Specifically, in combination Figure 1 and Figure 2 To elaborate further, four auxiliary lifting mechanisms 4 are specifically set up at this point, and the four auxiliary lifting mechanisms 4 are respectively set at the four corners of the base 2. In this way, when the platform 1 moves away from the base 2, the four auxiliary lifting mechanisms 4 can simultaneously provide four identical auxiliary lifting forces that are evenly applied to the platform 1, so that the platform 1 can rise more smoothly.

[0061] Of course, the number of auxiliary lifting mechanisms 4 mentioned above can be increased or decreased according to the actual usage scenario and the actual load size.

[0062] In one embodiment, the scissor arm mechanism 3 includes a scissor arm assembly 31, a drive motor 32, and a transmission component 33; both ends of the scissor arm assembly 31 are respectively connected to the platform 1 and the base 2; the drive motor 32 is fixedly installed in the base 2 and connected to the scissor arm assembly 31 through the transmission component 33; wherein, the drive motor 32 can adjust the angle formed between the scissor arm assembly 31 and the base 2 to change the actual support height of the scissor arm assembly 31 accordingly.

[0063] Specifically, in combination Figure 1 and Figure 2 In further detail, the scissor arm mechanism 3 is specifically configured to include a scissor arm assembly 31, a drive motor 32, and a transmission component 33. Both ends of the scissor arm assembly 31 are respectively connected to the platform 1 and the base 2. Thus, when the scissor angle of the scissor arm assembly 31 changes, the scissor arm assembly 31 can correspondingly change its length in the vertical direction, thereby achieving the function of driving the platform 1 to move up and down. The drive motor 32 is fixedly installed in the base 2 and connected to the scissor arm assembly 31 through the transmission component 33. The drive motor 32 can be, but is not limited to, a stepper motor, and the transmission component 33 can be, but is not limited to, a rotation-translation assembly (such as a gear mechanism, a lead screw and nut, etc.). This allows the rotation output by the drive motor 32 to be converted into translation at one end of the scissor arm assembly 31, thereby achieving the function of adjusting the angle between the scissor arm assembly 31 and the base 2, and changing the actual support height of the scissor arm assembly 31.

[0064] In one embodiment, the scissor arm assembly 31 includes at least one sliding sub-arm 311 that is slidably connected to the base 2; the transmission component 33 includes a transmission chain 331 and a transmission screw 332; the output shaft of the drive motor 32 is connected to the transmission screw 332 through the transmission chain 331; one end of the sliding sub-arm 311 is connected to the nut in the transmission screw 332 and can reciprocate relative to the base 2 with the nut when the transmission screw 332 rotates.

[0065] Specifically, in combination Figure 1 and Figure 3 In further detail, only one sliding sub-arm 311 is set in the scissor arm assembly 31. The other scissor arm in the scissor arm assembly 31 can be hinged to the base 2. The base 2 can be specifically provided with a limiting groove along the horizontal direction for the sliding sub-arm 311 to slide back and forth. One end of the sliding sub-arm 311 is correspondingly and slidably locked in the limiting groove. In this way, when the drive motor 32 drives the scissor arm assembly 31 through the transmission component 33, the sliding sub-arm 311 can change the angle with the other scissor arm by sliding back and forth along the limiting groove, thereby changing the angle formed between the scissor arm assembly 31 and the base 2, and changing the actual support height of the scissor arm assembly 31.

[0066] Of course, two sliding sub-arms 311 that scissor arms can be provided in the scissor arm assembly 31. Two limiting grooves are opened in the base 2 along the horizontal direction to allow the two sliding sub-arms 311 to slide back and forth. In this way, when the drive motor 32 drives the scissor arm assembly 31 through the transmission component 33, the two sliding sub-arms 311 that scissor arms can slide closer to each other or further away from each other along the limiting grooves. Similarly, the angle formed between the scissor arm assembly 31 and the base 2 can be changed, thereby changing the actual support height of the scissor arm assembly 31.

[0067] In addition, the transmission component 33 is specifically configured as a transmission chain 331 and a transmission screw 332, and the output shaft of the drive motor 32 is connected to the transmission screw 332 through the transmission chain 331. The nut in the transmission screw 332 is connected to one end of the sliding sub-arm 311 in the scissor arm assembly 31. In this way, when the drive motor 32 outputs forward or reverse, the nut can drive one end of the sliding sub-arm 311 to move back and forth relative to the base 2, thereby realizing the function of changing the actual support height of the scissor arm assembly 31.

[0068] Of course, the aforementioned transmission component 33 can also be configured as other transmission mechanisms, such as "gear and rack mechanism", "cam and linkage mechanism", etc., as long as it can convert the "rotation" output by the drive motor 32 into the "translation" of the sliding sub-arm 311.

[0069] In one embodiment, the lifting and transporting device further includes a switch assembly 5; the switch assembly 5 is electrically connected to the scissor arm mechanism 3 and the auxiliary lifting mechanism 4 respectively; wherein, when the platform 1 rises to the highest critical position, the switch assembly 5 can be triggered accordingly, and the upward movement of the scissor arm mechanism 3 and the auxiliary lifting mechanism 4 is stopped; when the platform 1 falls to the lowest critical position, the switch assembly 5 can be triggered accordingly, and the downward movement of the scissor arm mechanism 3 and the auxiliary lifting mechanism 4 is stopped.

[0070] Specifically, in combination Figure 2 and Figure 3 In further detail, the switch assembly 5 is connected to the scissor arm mechanism 3 and the auxiliary lifting mechanism 4. In this way, the switch assembly 5 can control the start and stop states of the scissor arm mechanism 3 and the auxiliary lifting mechanism 4 by opening and closing itself. When the platform 1 rises to the highest critical position or falls to the highest critical position, the switch assembly 5 can be triggered accordingly, thereby stopping the rising or falling movement of the scissor arm mechanism 3 and the auxiliary lifting mechanism 4.

[0071] The specific configuration of the aforementioned switch assembly 5 enables automatic sensing and triggering when the platform 1 rises or falls to a critical position, thereby automatically controlling the lifting and lowering limit position of the platform 1.

[0072] In one embodiment, the switch assembly 5 includes a first trigger switch 51, a second trigger switch 52, and a mounting member 53; the mounting member 53 is disposed vertically and protrudes from the base 2; the first trigger switch 51 and the second trigger switch 52 are respectively disposed at intervals from top to bottom in the mounting member 53.

[0073] Specifically, in combination Figure 2 and Figure 3 In further detail, the switch assembly 5 is specifically configured to include a first trigger switch 51, a second trigger switch 52, and a mounting member 53. The mounting member 53 is vertically positioned and protrudes from the base 2. The first trigger switch 51 and the second trigger switch 52 are respectively positioned at intervals from top to bottom within the mounting member 53. Both the first trigger switch 51 and the second trigger switch 52 can be, but are not limited to, limit switches. Thus, when the scissor arm assembly 31 in the scissor arm mechanism 3 extends to its longest position, the first trigger switch 51 can be triggered by the corresponding pressure of the scissor arm assembly 31; when the scissor arm assembly 31 retracts to its shortest position, the second trigger switch 52 can be triggered by the corresponding compression of the scissor arm assembly 31. This allows the switch assembly 5 to be triggered when the scissor arm assembly 31 is at its longest and shortest positions, respectively.

[0074] Of course, the first trigger switch 51 and the second trigger switch 52 in the switch assembly 5 can also be set as other types of trigger switches, such as infrared trigger switches. An infrared emitter is set in the scissor arm assembly 31. When the scissor arm assembly 31 is extended to its longest state, the infrared emitter can illuminate the first trigger switch 51 and trigger it accordingly. When the scissor arm assembly 31 is shortened to its shortest state, the infrared emitter can illuminate the second trigger switch 52 and trigger it accordingly. In this way, the switch assembly 5 can be triggered as the scissor arm assembly 31 is extended to its longest state and shortened to its shortest state.

[0075] The specific arrangement of the aforementioned switch assembly 5 has the advantages of simple structure and the ability to be triggered according to the extension limit state of the scissor arm mechanism 3.

[0076] In one embodiment, a conveyor belt 6 is also provided in the platform 1 along the horizontal direction; the conveyor belt 6 can feed materials into or out of the platform 1 in the horizontal direction.

[0077] Specifically, in combination Figure 1 In further detail, the conveyor belt 6 can be specifically, but not limited to, extending along the length of the platform 1. In this way, when the platform 1 is raised or lowered to a specific height, the conveyor belt 6 can feed the battery cell box into or out of the platform 1 in a horizontal direction, thereby further improving the automation level of the lifting and transporting device.

[0078] In one embodiment, the platform 1 is further provided with a translation cylinder 61 perpendicular to the conveying direction of the conveyor belt 6; the translation cylinder 61 is connected to the conveyor belt 6 for driving the conveyor belt 6 to move parallel in the platform 1.

[0079] Specifically, in combination Figure 1 In further detail, when the conveyor belt 6 extends along the length of the platform 1, the translation cylinder 61 can be specifically set along the width of the platform 1. In this way, the translation cylinder 61 can move and adjust the conveyor belt 6 along the width of the platform 1, so that the conveyor belt 6 can more flexibly feed the battery cell box into or out of the platform 1, further improving the flexibility of the conveying path of the conveyor belt 6.

[0080] In addition, this disclosure also provides a conveying system, which includes a feeding conveyor belt 7 and the above-mentioned lifting and transporting device; the platform 1 can be raised to be flush with the feeding conveyor belt to receive the material conveyed by the feeding conveyor belt 7.

[0081] Specifically, in combination Figure 4 In further detail, the conveying system can be used specifically, but not limited to, for the comprehensive conveying and transfer of battery cell boxes. The feeding conveyor belt 7 in the conveying system can be arranged in the same straight direction and correspond to the platform 1. The feeding conveyor belt 7 can be aligned with the conveyor belt 6 in the platform 1 when the platform 1 is raised or lowered to a fixed height, so that the material can be transferred to the conveyor belt 6 in the platform 1.

[0082] Furthermore, the feeding conveyor belt 7 can also include a reader for reading material information and a blocking cylinder for temporarily blocking materials. The reader can be, but is not limited to, an infrared scanning counter, so that the coded strips in the material can be scanned and counted to read the material information and identify and count the materials. The blocking cylinder can be, but is not limited to, a vertically extending cylinder, which can temporarily block the material by extending upward, thereby realizing intermittent material conveying.

[0083] The conveying system includes the aforementioned lifting and transporting device, and can achieve all the beneficial effects of the aforementioned lifting and transporting device, which will not be described in detail here.

[0084] 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0085] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
