Description

Technical Field

[0001] The invention relates to the technical field of conveying, and in particular to an intelligent pneumatic double-speed side-thrust mechanism for material box conveying. Background Art

[0002] In the field of automated production lines, especially in the efficient manufacturing process of photovoltaic panels, the material box conveying system is very important. It is directly related to whether the entire production line can run smoothly and unimpeded, as well as the stability and sustainability of production capacity. Since the production of photovoltaic panels involves a variety of raw materials and semi-finished products with different characteristics, such as silicon wafers, battery cells, and frame materials, each material has unique size, weight and transportation requirements, which puts forward the requirements of high flexibility and wide adaptability for the material box conveying system.

[0003] Among them, the most critical thing is that in the initial stage of production line startup, traditional mechanical transmission systems such as chains and belts often slip or start slowly when carrying heavy material boxes because they cannot overcome static friction. This undoubtedly slows down the overall transportation efficiency and may accelerate equipment wear and shorten the service life of the equipment due to long-term high-load startup.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0044] Please refer to Figure 1-Figure 4 In an embodiment of the present invention, an intelligent pneumatic double-speed side-thrusting mechanism for material box conveying is provided, comprising:

[0045] A base 1 on which two symmetrically arranged toothed discs 2 are rotatably arranged, and the toothed discs 2 are driven by a motor;

[0046] A speed chain 3 is connected between the two toothed plates 2, and the speed chain 3 is used to carry and drive the material box 10 to move;

[0047] A cylinder 4, which is fixed on the base 1 and has an output end;

[0048] A push plate 5, which is vertically fixed to the output end of the cylinder 4 and is used to push the material box 10 to move on the double-speed chain 3;

[0049] The motor and the cylinder 4 are both controlled by a controller;

[0050] Furthermore, at the initial stage of side-pushing the material box 10, the controller controls the cylinder 4 to provide a driving force so that the material box 10 moves on the double-speed chain 3, and then the controller controls the motor to take over the power output so that the double-speed chain 3 generates a circumferential movement and drives the material box 10 to move at a double speed;

[0051] Furthermore, the controller can automatically adjust the timing of the motor taking over power output according to the weight of the material box 10 .

[0052] That is to say, in this embodiment, the toothed disc 2 is driven to rotate by the motor, and the speed chain 3 is used as a transmission medium to carry and drive the material box 10 to move along a predetermined path. The structure of the speed chain 3 allows the material box 10 to move faster on the speed chain 3, thereby improving the conveying efficiency.

[0053] The cylinder 4 is fixed on the base 1 and connected to the push plate 5 through its output end to provide the necessary driving force for the material box 10 during the starting stage. Since the starting torque is large, direct driving by the speed chain 3 may cause slippage or slow starting, so the auxiliary role of the cylinder 4 is crucial.

[0054] In addition, in this embodiment, the controller is responsible for coordinating the work of the motor and the cylinder 4. At the start-up stage of the material box 10, the controller first controls the cylinder 4 to output power to push the material box 10 to start moving on the double-speed chain 3. Subsequently, according to the preset logic or the real-time detected weight of the material box 10, the controller switches to the motor drive mode in a timely manner, and uses the high efficiency of the double-speed chain 3 to accelerate the conveying.

[0055] Specifically, the speed chain 3 includes two belt bodies 31 which are symmetrically arranged, and a plurality of first wheel bodies 32 are rotatably connected between the two belt bodies 31, and the second wheel bodies 33 are sleeved on the outer parts of the first wheel bodies 32;

[0056] A guide rail 9 for supporting the first wheel body 32 is fixed on the base 1 .

[0057] Among them, since the outer diameter of the second wheel body 33 is larger than the outer diameter of the first wheel body 32, when the first wheel body 32 rotates on the guide rail 9, the second wheel body 33 will rotate at a faster linear speed (the angular velocity of the first wheel body 32 and the second wheel body 33 is the same), thereby driving the material box 10 to move at double the speed.

[0058] In addition, the guide rail 9 not only provides support for the first wheel body 32, but also ensures that they can rotate smoothly along the predetermined path. This design helps to reduce friction and wear, improve the stability and durability of the system, and the double speed effect can only be achieved when the first wheel body 32 contacts the guide rail 9.

[0059] In addition, there is a first distance L1 between the guide rail 9 and the left end of the crankset 2, which is used to limit the minimum distance that the cylinder 4 drives the material box 10 to move.

[0060] There is a second distance L2 between the guide rail 9 and the right end of the chainring 2 so as to release the double-speed driving effect provided by the double-speed chain 3 on the material box 10 in advance.

[0061] Among them, the first distance L1 between the guide rail 9 and the left end of the chainring 2 limits the minimum distance that the cylinder 4 drives the material box 10 to move, ensuring that the material box 10 can obtain sufficient thrust during the starting stage to overcome the static friction and starting torque, thereby starting smoothly.

[0062] The "restriction" here does not refer to physical obstruction or constraint, but means that the cylinder 4 needs to drive the material box 10 to move at least the first distance L1 to ensure that the material box 10 is completely located on the corresponding speed chain 3 above the guide rail 9. In this way, when the motor takes over the power output, the speed chain 3 can more effectively drive the material box 10 to accelerate and stably transport.

[0063] The second distance L2 exists in order to release the double-speed driving effect of the double-speed chain 3 on the material box 10 in advance at an appropriate time. When the material box 10 approaches the conveying end or needs to slow down, continuing to drive at double speed may cause the material box 10 to be too fast and out of control. Therefore, by designing the second distance L2 between the guide rail 9 and the right end of the chainring 2, it can be ensured that the double-speed driving effect is released in advance when the material box 10 moves to this position. The key here is that the double-speed effect will only be achieved when the first wheel body 32 contacts the guide rail 9.

[0064] In this embodiment, an adsorption component 6 is also provided on the push plate 5 for adsorbing the material box 10, so that when the material box 10 is driven to move by the double-speed chain 3, the push plate 5 moves with the movement of the material box 10, thereby assisting in straightening the material box 10.

[0065] The main function of the suction component 6 is to suction the material box 10. This suction can usually be achieved by magnetic force, vacuum suction or other forms of non-contact force. During the conveying process of the material box 10, the suction component 6 ensures that the material box 10 and the push plate 5 maintain a stable connection, and can effectively prevent the material box 10 from deflecting or tipping over even during dynamic movement.

[0066] For example: magnetic adsorption, if the material box 10 or the push plate 5 is made of magnetic material, or a magnetic patch is used, magnetic adsorption can directly combine the two tightly.

[0067] For example, vacuum suction can generate negative pressure in the adsorption assembly 6 through a vacuum pump or a similar device, thereby forming a stable adsorption force between the push plate 5 and the material box 10 .

[0068] It is worth mentioning that the adsorption assembly 6 can adapt to material boxes 10 of different sizes, shapes and weights, thereby enhancing the versatility and flexibility of the equipment.

[0069] In practical applications, the push plate 5 with the adsorption assembly 6 can significantly improve the reliability and efficiency of the conveying of the material box 10. Especially in an automated production line or a logistics system, stable conveying of the material box 10 is the key to ensuring the smooth progress of subsequent processes.

[0070] In this embodiment, the cylinder 4 includes:

[0071] The cylinder body 41 has a piston 44 in a sealing and sliding connection therein, and the piston 44 divides the cylinder body 41 into a left space and a right space;

[0072] A rod body 45, one end of which is connected to the piston 44, and the other end of which is sealed and slidable to pass through the cylinder body 41;

[0073] A first air control hole 42, which is disposed in the left side space and connected to an external air control device;

[0074] A second air control hole 43, which is disposed in the right side space and connected to an external air control device;

[0075] A valve body 47 is provided on the bypass pipe 46 communicating with the left space and the right space.

[0076] In addition, a deceleration spring 48 is arranged in the right side space.

[0077] The position of the piston 44 is adjusted by regulating the gas in the left space and the right space through external gas control equipment, thereby realizing the movement of the rod body 45.

[0078] In addition, the bypass pipe 46 connects the left space and the right space, allowing gas to flow between the two spaces (the left space and the right space). However, this flow is controlled by the valve body 47. Under certain circumstances (such as when the motor takes over the power output), the valve body 47 will open, allowing gas to flow freely between the two spaces, so that the movement of the piston 44 and the rod body 45 is not directly affected by the gas pressure in the cylinder body 41.

[0079] It should also be explained that, in this embodiment, the deceleration spring 48 is arranged in the right space, and when the cylinder 4 needs to decelerate or stop, it can provide a certain resistance to assist in achieving the deceleration effect. In particular, when the material box 10 approaches the conveying end or needs to decelerate, the deceleration spring 48 can work in conjunction with the deceleration mechanism of the speed chain 3 to ensure that the material box 10 can be smoothly decelerated and stopped at a predetermined position.

[0080] The specific implementation includes the following stages:

[0081] Start-up phase: In the start-up phase, the cylinder 4 pushes the push plate 5 through its rod body 45, thereby pushing the material box 10 to move on the speed chain 3. At this time, the valve body 47 is closed.

[0082] Motor takes over power output: When the motor takes over power from the cylinder 4, the valve body 47 opens to allow gas to flow between the left and right spaces. In this way, the movement of the piston 44 and the rod body 45 is no longer directly affected by the gas pressure in the cylinder 41, but moves with the movement of the push plate 5 and the material box 10.

[0083] Deceleration and stop: When the material box moves to the second distance L2 between the guide rail 9 and the right end of the chainring 2, the deceleration mechanism of the speed chain 3 is used to release the speed driving effect of the speed chain 3 on the material box 10 in advance. The deceleration spring 48 plays a certain auxiliary role in this process, helping the material box 10 to decelerate smoothly and stop at a predetermined position.

[0084] In this embodiment, the adsorption component 6 includes:

[0085] An adsorption seat 61 is fixed on the push plate 5, and a suction cup 62 is fixedly embedded in the middle of the adsorption seat 61. The suction cup 62 has a through hole and a negative pressure groove connected to the through hole. An annular groove 64 is opened in the through hole.

[0086] A plug 63, one end of which is provided with a column groove and the other end is conical, for blocking the through hole, and a side hole 65 communicating with the column groove is provided on the side of the plug 63, and the side hole 65 corresponds to the annular groove 64;

[0087] A bottom plate 66, which is fixed in the through hole, and the bottom plate 66 is a grid structure;

[0088] A return spring 67 connected between the column slot and the bottom plate 66;

[0089] The push plate 5 is provided with a vent hole 51 corresponding to the through hole.

[0090] In addition, a limited position straightening head 68 is fixed on the adsorption seat 61 .

[0091] The through hole of the suction cup 62 cooperates with the negative pressure groove, allowing negative pressure to be formed in the negative pressure groove, thereby sucking the material box 10 .

[0092] When the material box 10 needs to be adsorbed, the adsorption component 6 is pressed against one side of the material box 10 by moving the push plate 5. At this time, the gas in the negative pressure groove pushes the plug 63 to move to the left, and the gas in the negative pressure groove flows through the through hole, the annular groove 64, the side hole 65, the column groove, the bottom plate 66 and is discharged from the vent hole 51. At this time, negative pressure is formed in the negative pressure groove, and the suction cup 62 adsorbs the material box 10.

[0093] The return spring 67 maintains the position of the plug 63 under the negative pressure state, ensuring the continuous effect of the adsorption force.

[0094] During the conveying process, the limiting and straightening head 68 assists in straightening the material box 10 to prevent it from deflecting or tipping over.

[0095] When the material box 10 needs to be released, the material box 10 can be separated from the adsorption assembly 6 by external force, for example, by pulling the material box 10 upward.

[0096] In this embodiment, a guide rod 7 is fixed on the base 1 , a slide seat 8 is slidably provided on the guide rod 7 , and the slide seat 8 is connected to the push plate 5 .

[0097] When the cylinder 4 is started, its output end pushes the push plate 5 to move. Since the push plate 5 is connected to the slide 8, the slide 8 will slide along the guide rod 7. The guide rod 7 provides a stable sliding path for the slide 8, preventing the push plate 5 from deflecting and shaking during the movement.

[0098] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
