Description

Technical Field

[0001] The utility model relates to the technical field of stacking equipment, in particular to a variable-pitch fork stacker and a transfer system. Background Art

[0002] In the current lithium battery production process, as the production capacity and production layout requirements continue to increase, manufacturers are facing the need for efficient logistics and storage systems. In order to achieve effective transportation and storage of batteries, many lithium battery production factories have begun to use automated stacking machinery. Among them, the double-fork stacker has become a widely used transportation and storage solution due to its efficient handling performance and strong adaptability.

[0003] In the lithium battery industry, double-fork stackers are mainly used for battery transportation and storage in capacity separation and normal temperature storage warehouses. Capacity separation, as a key process in battery production, involves the classification of battery capacity, which is an important step to ensure the consistency of battery performance. Normal temperature storage warehouses are used to store classified batteries for subsequent assembly or further testing. The efficient operation of these two links is of great significance to improving production efficiency and reducing costs.

[0004] However, with the advancement of technology and market demand, the existing double-fork stacker has exposed certain limitations in actual application. Especially in the use of capacity-dividing equipment and normal temperature static warehouses, since the distance between cabinets and warehouse locations in these two scenarios is inconsistent, and the distance between forks in the standard double-fork stacker design is fixed, it is difficult for a stacker to simultaneously meet the needs of these two different space layouts. This limitation not only reduces the efficiency of logistics transfer, but may also lead to additional equipment investment and increase production costs.

[0005] Therefore, how to achieve compatibility of existing double-fork stacker cranes with different storage location spacings has become a technical problem that needs to be solved urgently. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0025] like Figure 1 As shown, in order to achieve the above-mentioned purpose, the utility model proposes a variable-pitch fork stacker, comprising:

[0026] A support platform 30, wherein at least one guide rail 50 is provided on the support platform 30;

[0027] A first slider 11 is slidably connected to the guide rail 50 and can reciprocate along the length direction of the guide rail 50. The first slider 11 is connected to a first fork 21 that can be extended or retracted relative to the slider. The length direction of the first fork 21 is not parallel to the guide rail 50.

[0028] The second slider 12 is slidably connected to the guide rail 50 and can reciprocate along the length direction of the guide rail 50 to adjust the distance between itself and the first slider 11. The first slider 11 is connected to a second fork 22 that can extend or retract relative to the second slider 12 and keep synchronous movement with the first fork 21. The length direction of the second fork 22 is parallel to the first fork 21.

[0029] Specifically, a variable-length fork stacker includes the following main components: a support platform 30 , a first slide block 11 , a second slide block 12 , a first fork 21 , and a second fork 22 .

[0030] The support platform 30 serves as the foundation of the stacker and stably supports other components. The support platform 30 has sufficient strength and stability to ensure safety and reliability during operation. At least one guide rail 50 is provided on the support platform 30.

[0031] The first slider 11 is slidably connected to the guide rail 50 on the support platform 30 and can reciprocate along the length direction of the guide rail 50. The first slider 11 is moved by a driving mechanism (such as an electric motor, a hydraulic system or other appropriate driving device). A first fork 21 is fixed or connected to the first slider 11. The first fork 21 can be extended or retracted relative to the first slider 11 by hydraulic, electric or other mechanical devices to fork or release goods.

[0032] The second slider 12, like the first slider 11, is also slidably connected to the guide rail 50 and can also reciprocate along the length direction of the guide rail 50. The second slider 12 can share a driving mechanism with the first slider 11, and of course the second slider 12 can also have its own independent driving system control so as to adjust the distance between it and the first slider 11. This distance adjustability allows the variable-distance fork stacker to adapt to pallets or goods of different widths.

[0033] The second fork 22 is also connected to the second slider 12, and the second fork 22 can extend or retract synchronously with the first fork 21. The length direction of the second fork 22 must be parallel to the first fork 21, so as to ensure stability and uniform force distribution when carrying goods. In the present application, the number of guide rails 50 is two.

[0034] By adopting the above technical solution, the variable-distance fork stacker can adapt to goods of different sizes by adjusting the distance between the two forks, thereby improving the applicability and efficiency of the equipment.

[0035] In one embodiment of the present application, both ends of the guide rail 50 are provided with a stop block 40 to prevent the first slider 11 and the second slider 12 from falling off the guide rail 50 .

[0036] Specifically, stop blocks 40 are installed at both ends of the guide rail 50. The main function of the two stop blocks 40 is to prevent the first slider 11 and the second slider 12 from falling off the guide rail 50 during movement. The stop blocks 40 are usually made of strong and durable materials such as metal or alloy to withstand the impact force of the slider.

[0037] The stop blocks 40 are placed at the two ends of the guide rail 50 to ensure that when the slider moves to the limit position, the slider can be prevented from continuing to move and falling off the guide rail 50. This not only protects the safety of the staff and avoids mechanical accidents caused by the slider falling off, but also ensures the service life of the machine itself and prevents excessive wear and impact.

[0038] By adopting the above technical solution, the stopping block 40 can prevent the first slider 11 and the second slider 12 from falling off the guide rail 50 .

[0039] In one embodiment of the present application, a photoelectric sensor for detecting the position of the first slider 11 and / or the second slider 12 is provided on one side of the guide rail 50 .

[0040] Specifically, a photoelectric sensor is provided on one side of the guide rail 50. The photoelectric sensor is used to monitor and detect the position of the first slider 11 and / or the second slider 12 in real time. The photoelectric sensor determines the position of the object by emitting a light beam and receiving a reflected light beam or a light beam transmitted through the object. When the slider moves into the detection range of the sensor, the photoelectric sensor can sense the position of the slider and output it in the form of an electrical signal, thereby determining the position of the slider. In this way, the operator or the automatic control system of the stacker can accurately know the real-time position of each slider to determine whether the slider has entered the working position, which is convenient for accurate control and operation.

[0041] In addition, the photoelectric sensor can not only accurately detect the position of the slider, but also monitor the movement speed and status of the slider in real time, providing key motion parameters, which is conducive to the precise control of the entire system.

[0042] In one embodiment of the present application, a driving member for driving the first slider 11 and the second slider 12 to make the first slider 11 and the second slider 12 approach or move away from each other is provided on one side of the guide rail 50 .

[0043] Specifically, a driving member is installed on one side of the guide rail 50 to control the first slider 11 and the second slider 12 to move along the length direction of the guide rail 50, so that the first slider 11 and the second slider 12 are moved closer to or farther from each other. The driving member can be in various forms, including but not limited to an electric motor, a hydraulic drive system, a pneumatic drive system, and a ball screw. This ensures that the two sliders move closer to or farther from each other in a desired manner and speed. The drive of the driving member allows the stacker to quickly and accurately adjust the spacing of the forks to accommodate various cargo sizes from narrow to wide.

[0044] In an embodiment of the present application, the driving member is a ball screw having a first thread and a second thread in opposite directions. The first fork 21 is threadedly connected to the first thread, and the second fork 22 is threadedly connected to the second thread.

[0045] Specifically, the driving member in the present application is a ball screw, which is responsible for driving the first slider 11 and the second slider 12 to move. The ball screw is provided with two sets of threads, namely the first thread and the second thread, and the directions of the two sets of threads are opposite.

[0046] In the ball screw drive system, the forks connected to the first slider 11 and the second slider 12 are respectively provided with threaded parts, the first fork 21 is threadedly connected to the first thread, and the second fork 22 is threadedly connected to the second thread.

[0047] When the ball screw rotates, since the first thread and the second thread are in opposite directions, the two sliders will move closer or farther away from each other according to the direction of the screw rotation, so that the fork can adjust the width in a precise and smooth manner to adapt to goods of different sizes.

[0048] In one embodiment of the present application, travel switches are further provided at both ends of the guide rail 50 for limiting the operation of the driving member when the first slider 11 and the second slider 12 abut against the stop block 40 .

[0049] Specifically, when the first slider 11 and the second slider 12 move to the end of the guide rail 50 and finally abut against the stop block 40, the travel switch is triggered, and the travel switch sends a signal to the control system to instruct the driving member to stop further operation.

[0050] By adopting the above technical solution, the travel switch is set to prevent excessive wear of the equipment and increase the service life of the equipment.

[0051] In one embodiment of the present application, the support platform 30 is further provided with a camera module 60 for detecting whether there is cargo to be forked.

[0052] Specifically, the camera module 60 provided on the supporting platform 30 mainly functions to detect whether the cargo to be forked exists. Through the detection of the camera module 60, the intelligence and automation level of the equipment during operation can be enhanced.

[0053] The camera module 60 is connected to a central control system or a dedicated image processing unit. When the support platform 30 reaches the designated position, the camera scans the cargo stacking area. Through the image recognition algorithm, the system can identify the target cargo and verify whether it is ready for fork pick-up.

[0054] In one embodiment of the present application, a detection member 70 for detecting the size of the cargo to be forked is further provided on the support platform 30 .

[0055] Specifically, the detection component mounted on the support platform 30 is used to measure the size of the cargo to be forked. The detection component can be a laser rangefinder, an ultrasonic sensor, or a visual measurement system. The detection component accurately measures the length, width, height and other dimensional information of the cargo to avoid the cargo exceeding the set value and causing damage to the cargo.

[0056] The detailed working process of the device of this application is as follows:

[0057] After the battery reaches the rated time in the capacity distribution equipment or completes the static time in the normal temperature area, the scheduling system will send a signal to the stacker to start the transfer or storage task.

[0058] After the stacker receives the signal, it starts to move along the ceiling rail and the ground rail, and the loading platform performs vertical and horizontal positioning movements along the columns to ensure that the stacker accurately reaches the designated pickup location.

[0059] While the stacker is moving, the first fork 21 and the second fork 22 are driven by the ball screw to move closer to or farther from each other, thereby reaching a distance that matches the goods.

[0060] After confirming that the first fork 21 and the second fork 22 have reached the designated position, the stacker uses the camera module 60 to confirm whether there is a pallet at the pickup position. If a pallet is detected, the first fork 21 and the second fork 22 extend to pick up the pallet and move the pallet to the loading platform.

[0061] Before the pallet is moved into the loading platform, the size of the pallet is measured by the size detection member 70 to ensure that the size of the pallet is appropriate and is correctly placed in the loading platform.

[0062] When the size of the pallet does not meet the requirements, an alarm message is issued and manual processing is required.

[0063] In one embodiment of the present application, the detection element is a laser radar.

[0064] The present application also discloses a transfer system, comprising the variable-length fork stacker as described in any one of the above.

[0065] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
