Description

Technical Field

[0001] The present application relates to the field of building panels, and in particular to a loading and unloading workstation. Background Art

[0002] At present, in the purification board industry, the raw material boards are usually placed one by one on the roller rack for conveying the boards, and are sequentially conveyed to each work station through the conveyor belt. This conveying method has a gap between the two boards that are conveyed sequentially, which causes operational inconvenience for some work stations that need to process the boards continuously. For example, the length of a single purification board is often greater than the length of a single raw material board. Therefore, some raw material boards need to be cut to match the length of the purification board by splicing multiple raw material boards. Or in the glue spraying process, in order to maintain the uniformity of glue spraying between each board, it is generally hoped that the boards can be conveyed continuously without spacing. In the above scenarios, the existing production lines are prone to problems such as difficulty in controlling the cutting length of the boards or uneven distribution of the adhesive due to the gap between the two boards. Utility Model Content

[0003] Multiple aspects of the present application provide a loading and unloading workstation to solve one or more of the above-mentioned problems.

[0004] An embodiment of the present application provides a loading and unloading workstation, comprising: a loading and unloading area and a working area, wherein the loading and unloading area is used to take and place plates, and the working area is provided with a conveying device and a loading and unloading equipment. The conveying device comprises a first conveying track, a second conveying track and a power source. The power source is respectively connected to the first conveying track and the second conveying track, and is used to drive the first conveying track and the second conveying track to convey the plates, wherein the conveying speed of the first conveying track is greater than the conveying speed of the second conveying track. The loading and unloading equipment is arranged on one side of the first conveying track, and is used to take and place the plates between the loading and unloading area and the first conveying track. When the loading and unloading equipment places the plates on the first conveying track, there is a gap between the plates and the previous plates on the second conveying track, and the gap is reduced or eliminated when the first conveying track conveys the plates to the second conveying track.

[0005] In some embodiments, a top surface of the first conveying track is higher than a top surface of the second conveying track.

[0006] In some embodiments, a side of the first conveying track away from the second conveying track is higher than a side of the first conveying track close to the second conveying track.

[0007] In some embodiments, the conveying device further includes: a roller frame and a ruler. The roller frame has two opposite guide brackets and a fixed bracket spanning the two guide brackets. The first conveying track and the second conveying track are respectively arranged between the two guide brackets, and the fixed bracket is suspended above the second conveying track.

Wherein, a plurality of rollers are arranged on the side of the ruler facing the second conveying track, and the plurality of rollers limit the plate to be transported within the predetermined height and roll on the surface of the plate.

[0008] In some embodiments, the conveying device further includes a roller, which is disposed on the second conveying track at a side close to the first conveying track, and the outer peripheral surface of the roller is respectively against the surface of the second conveying track and the end of the ruler facing the first conveying track. When the power source drives the second conveying track to operate, the second conveying track drives the roller to rotate, and when the sheet is transferred to the second conveying track, the roller presses against the sheet by its own weight, guiding the sheet to be transferred between the ruler and the second conveying track.

[0009] In some embodiments, the loading and unloading equipment includes a robot body and a gripper. The gripper has a coupling, a fixed bracket and a plurality of mounting brackets.

[0010] In some embodiments, the adsorption assembly includes a buffer rod, a vacuum generator and a suction cup. The buffer rod is connected to the mounting bracket, and the vacuum generator is connected between the buffer rod and the suction cup to generate vacuum suction in the suction cup when the suction cup is attached to the surface of the plate.

[0011] In some embodiments, the loading and unloading device further includes a control device, which is electrically connected to the robot body and the gripper, respectively, to control the movement of the robot body and the opening and closing of the vacuum generator, and to detect the vacuum state in the suction cup. When the suction cup does not present the vacuum state, the control device turns off all vacuum generators located on the same mounting bracket as the suction cup.

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0024] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0025] See also Figures 1 to 9 , the embodiment of the present application provides a loading and unloading workstation 20, which is suitable for a plate production line. The loading and unloading workstation 20 includes a loading and unloading area 21 and a working area 22. Among them, the loading and unloading area 21 can be the ground or a containing structure on one side of the plate production line, which is used to take and place the plate 81, and the working area 22 is provided with a conveying device 70 and a loading and unloading device 23. It is worth noting that the plate referred to in this embodiment can be but is not limited to a purification plate or a sandwich layer of a purification plate, and the sandwich layer can be a gypsum board or an aluminum honeycomb structure.

[0026] The conveying device 70 includes a first conveying rail 711, a second conveying rail 712 and a power source 73A. The first power source 73A is used to drive the conveying rail 71 to convey the plate 81. In this embodiment, the first power source 73A is connected between the first conveying rail 711 and the second conveying rail 712, and can drive the first conveying rail 711 and the second conveying rail 712 to convey the plate 81, and the conveying speed of the first conveying rail 711 is greater than the conveying speed of the second conveying rail 712. For example, the first power source 73A is a motor, the first conveying rail 711 and the second conveying rail 712 are conveyor belts, and a transmission mechanism (such as a speed reduction mechanism) is provided between the motor and the conveyor belt, so that the two conveyor belts can be driven to produce different conveying speeds.

[0027] The loading and unloading device 23 is disposed on one side of the first conveying track 711, and is used to take and place the plate 81 between the loading and unloading area 21 and the first conveying track 711. When the loading and unloading device 23 places the plate 81 on the first conveying track 711, there is a gap between the plate 81 and the previous plate 81 on the second conveying track 712, and the transmission speed of the first conveying track 711 is greater than the transmission speed of the second conveying track 712, so that when the first conveying track 711 transmits the plate 81 to the second conveying track 712, the gap between the two plates 81 is reduced, or the gap between the two plates 81 is eliminated so that they are close to each other. Figure 4 As shown, through the above speed difference, after the plates 81 are placed one by one on the first conveying track 711, they can quickly move toward the second conveying track 712 and abut against the previous plate 81 to avoid a gap between the two plates and affect the accuracy of the cutting position.

[0028] In this embodiment, the loading and unloading equipment 23 is an intelligent robot, and includes a robot body 231 and a gripper 232. The gripper 232 includes a coupling 2321, a fixed frame 2322 and a plurality of mounting brackets 2323. The coupling 2321 and the plurality of mounting brackets 2323 are respectively arranged on two opposite sides of the fixed frame 2322, and the robot body 231 is connected to the coupling, so that the robot body 231 drives the gripper 232 through the coupling 2321 to pick up and place the plate 81 between the loading and unloading area 21 of the loading and unloading workstation 20 and the first conveying track 711. In addition, the plurality of mounting brackets 2323 are arranged at intervals along the extension direction of the fixed frame 2322, and a plurality of adsorption components 233 are arranged at intervals on each mounting bracket 2323, and the plate 81 can be picked up and placed as the gripper 232 moves.

[0029] In addition, the adsorption assembly 233 includes a buffer rod 2331, a vacuum generator 2332 and a suction cup 2333. The buffer rod 2331 is connected to the mounting bracket 2323, and the vacuum generator 2332 is connected between the buffer rod 2331 and the suction cup 2333, so as to generate vacuum suction in the suction cup 2333 when the suction cup 2333 is attached to the surface of the plate 81, so as to firmly adsorb the plate 81.

[0030] For example, the loading and unloading equipment 23 can be a 4-axis robot, and the fixed frame 2322 is set at the end of the gripper 232, and can be displaced in 3D space with the gripper 232. Among them, the fixed frame 2322 is welded from steel, and has the advantages of strong rigidity and light weight, and the suction cup is a rubber vacuum suction cup with a diameter of 80mm, which can provide sufficient adsorption area to improve the adsorption effect. Therefore, during operation, the gripper 232 can move in 3D between the loading and unloading area 21 and the first conveying track 711, and firmly adsorb the plate 81 through the multiple adsorption components 233 on the mounting bracket 2323, so as to transport the plate 81 to the first conveying track 711 for transmission, processing and other related operations.

[0031] It is worth noting that since the suction cup 2333 is equipped with a buffer rod 2331, it can ensure elastic adjustment when the surface of the plate 81 is uneven, and reduce external vibration or impact during the adsorption process, and each suction cup 2333 can control adsorption or release individually. For example, when there is a slight unevenness or error on the surface of the material adsorbed by the suction cup assembly 233, the buffer rod 2331 can make slight elastic adjustments while in contact to cope with changes in the material surface, ensuring that the adsorption effect is not affected by surface irregularities. Therefore, the configuration of the buffer rod 2331 helps the suction cup 2333 maintain a stable adsorption effect under various uncertain conditions and reliably handle materials of different shapes and surface states.

[0032] In some embodiments, the loading and unloading device 23 further includes a control device 234, which is electrically connected to the robot body 231 and the gripper 232, respectively. In this way, the control device 234 can control the movement of the robot body 231, the opening and closing of the vacuum generator 2332, and the detection of the vacuum state in the suction cup 2333 by presetting or real-time operation, so as to achieve the movement, adsorption and release of the plate 81, and when a vacuum state is not present in a certain suction cup 2333, the control device 234 turns off all vacuum generators 2332 on the same mounting bracket 2323 as the suction cup 2333. In other words, in the control of the suction cup assembly 233, it can also be set to regional synchronous adsorption, for example, the mounting bracket 2323 is a cross bar, and multiple suction cup assemblies 233 are arranged at intervals along the extension direction of the cross bar, and the suction cup assembly 233 on each cross bar can be actuated synchronously. When the surface error of the material is too large and some suction cup assemblies 233 cannot absorb the material, the suction cup assemblies 233 in the same row will automatically close without affecting the use of suction cup assemblies 233 on other mounting brackets 2323. This regional synchronization design can effectively improve the efficiency of the system, ensuring that timely measures can be taken when problems occur in a specific area to interrupt unnecessary suction actions without adversely affecting the overall operation.

[0033] In order to effectively improve the conveying efficiency of the plate 81, in some embodiments, the top surface of the first conveying track 711 is higher than the top surface of the second conveying track 712, forming a conveying method from high to low. For example, the side of the first conveying track 711 away from the second conveying track 712 is higher than the side close to the second conveying track 712, so that the first conveying track 711 is inclined from top to bottom toward the second conveying track 712, so that the plate 81 can be assisted by gravity during the conveying process, which helps to improve the conveying efficiency.

[0034] like Figure 8 As shown, in order to improve the stability of the plate 81 during the conveying process, in some embodiments of the present application, a fixed bracket 741 is provided above the second conveying track 712, and a ruler 75 is provided between the fixed bracket 741 and the second conveying track 712. In this embodiment, the fixed bracket 741 spans over the two guide brackets 72 and is suspended above the second conveying track 712. The ruler 75 is provided between the fixed bracket 741 and the second conveying track 712, and has a predetermined height with the second conveying track 712, and the predetermined height matches the thickness of the plate 81, so that the plate 81 can be restricted to be conveyed between the ruler 75 and the second conveying track 712. Among them, a plurality of rollers 751 are provided on the side of the ruler 75 facing the second conveying track 712, and the plurality of rollers 751 can roll on the top surface of the plate 81 during the conveying process of the plate 81, so that the plate 81 is clamped between the rollers 751 and the second conveying track 712, thereby limiting the plate 81 within the above-mentioned predetermined height to achieve stable conveying.

[0035] Similarly, in order to further improve the stability of the sheet 81 during the conveying process, in some embodiments, a roller 76 is provided on the side of the second conveying track 712 close to the first conveying track 711. The roller 76 may be, but is not limited to, a cylinder, and the outer circumferential surface of the roller 76 abuts against the surface of the second conveying track 712 and the end of the scale 75 facing the first conveying track 711. It is worth mentioning that in this embodiment, the roller 76 is not provided with a fixed structure, but is directly placed on the second conveying track 712, and its movement is restricted by the end of the scale 75. Therefore, when the first power source 73A drives the second conveying track 712 to operate, the second conveying track 712 drives the roller 76 to abut against the end of the scale 75 and generate self-rotation, so that when the sheet 81 is conveyed to the second conveying track 712, the roller 76 presses against the sheet 81 by its own weight, and can guide the sheet 81 to be conveyed between the scale 75 and the second conveying track 712, thereby ensuring the stability of the conveying process.

[0036] In addition, in such an industrial environment, in order to further improve safety and prevent accidental risks in the operating area of ​​the loading and unloading equipment 23, a safety fence is also set around the loading and unloading equipment 23 to prevent workers from entering the working area of ​​the loading and unloading equipment 23 to avoid accidents. For example, the safety fence is 1800mm high and is set on one side of the loading and unloading equipment 23. It is designed with a yellow warning color so that workers can clearly identify it and avoid mistakenly entering the working area of ​​the loading and unloading equipment 23. Of course, in addition to being set around the loading and unloading equipment 23, the safety fence can also be set at the entrance of other production lines, or in areas where workers are easily injured, separating non-working areas, which can effectively reduce the occurrence of industrial accidents.

[0037] Alternatively, the loading and unloading equipment 23 may also be provided with a safe operation mode, for example, with functions such as emergency stop, fault alarm, start, and pause. In some embodiments, the safety fence is also provided with a grating, and is linked with the robot body 231. Once the grating system detects that someone has entered the range of the safety fence, it will send a stop signal to the robot body 231 to quickly interrupt its action. At the same time, the robot body 231 will trigger a warning signal to the control device 234, or a warning device is provided around the loading and unloading equipment 23, which directly receives the warning signal of the robot body 231 and triggers sound and light warnings, reminding on-site personnel to stay away from dangerous areas, so that personnel and the loading and unloading equipment 23 can work together more safely in the same working environment.

[0038] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
