[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] With increasing automation, pallet processing has become automated, enabling mass production. However, pallet dimensions, especially the flatness of the surface supporting the workpiece and the mounting surface during transport, still require manual measurement. The main measurement process includes: manual handling, cleaning, clamping to the measuring unit, coordinate measuring machine (CMM) measurement, manual disassembly, and manual adjustment of pallet dimensions. This process requires manual intervention in multiple steps, resulting in low efficiency, extended production cycles, and limited large-scale pallet use.

[0049] To solve the above problems, such as Figure 1 As shown in the figure, this embodiment proposes an automatic pallet measuring device, which includes a loading / unloading mechanism 1, a cleaning mechanism 2, a buffer mechanism 3, a measuring mechanism 4, and a transfer mechanism 5. The loading / unloading mechanism 1 can move between an external loading / unloading station and an internal loading / unloading station to transfer pallets to be measured from the external loading / unloading station to the internal loading / unloading station and to transfer qualified pallets from the internal loading / unloading station to the external loading / unloading station. The cleaning mechanism 2 can clean the pallets to be measured that are transferred to the cleaning mechanism 2. The buffer mechanism 3 can store the cleaned pallets to be measured. The measuring mechanism 4 can measure whether the pallets entering the measuring mechanism 4 are qualified. The transfer mechanism 5 can drive the pallets to flow sequentially between the internal loading / unloading station, the cleaning mechanism 2, the buffer mechanism 3, and the measuring mechanism 4, and transfer qualified pallets to the internal loading / unloading station.

[0050] In this embodiment, the transfer mechanism 5 drives the pallet to flow sequentially between the internal loading / unloading station, the cleaning mechanism 2, the buffer mechanism 3, and the measuring mechanism 4. After being cleaned by the cleaning mechanism 2, the pallet to be measured is stored in the buffer mechanism 3. Then, the transfer mechanism 5 transfers the pallet from the buffer mechanism 3 to the measuring structure for measurement, and transfers the qualified pallet back to the internal loading / unloading station. This automatic pallet measuring equipment achieves automatic loading / unloading, automatic cleaning, automatic storage, and automatic measurement, thus realizing an automated pallet measurement process with minimal human intervention, improving both measurement and production efficiency.

[0051] It should be noted that the transfer mechanism 5 is located in the middle of the workbench. The loading and unloading mechanism 1, cleaning mechanism 2, buffer mechanism 3, and measuring mechanism 4 are arranged around the transfer mechanism 5 on the workbench so that the transfer mechanism 5 can transfer the pallet to each mechanism in sequence, making the layout of each component on the workbench more reasonable and compact.

[0052] In this embodiment, the transfer mechanism 5 is a multi-joint robot. Through the coordinated movement of its joints, the pallet is flexibly transferred between different mechanisms. Specifically, the multi-joint robot is equipped with a pallet type recognition sensor to determine the type of pallet to be picked up or placed. The multi-joint robot uses grippers to pick up or release the pallet, achieving stable transfer. Since multi-joint robots are existing technology, their specific structure and working principle will not be described in detail.

[0053] This embodiment has three different types of pallets. In other embodiments, the type and size of the pallets can be flexibly adjusted, and no specific limitation is made here. The measuring mechanism 4 mainly detects the flatness of the bearing surface and mounting surface of different types of pallets to determine whether the pallets are qualified. If the flatness of the bearing surface and mounting surface of the pallet is within the acceptable range, the pallet is judged to be qualified; if the flatness of the bearing surface and mounting surface of the pallet is not within the acceptable range, the pallet is judged to be unqualified. Of course, the measuring mechanism 4 can also detect other dimensions of the pallet according to actual needs, and no specific limitation is made here.

[0054] The loading / unloading mechanism 1 in this embodiment includes a precision linear guide, a servo motor, a reducer, a gear and rack meshing assembly, and a slide table. One end of the precision linear guide extends into the internal loading / unloading station inside the worktable, and the other end extends into the external loading / unloading station outside the worktable. The slide table slides in conjunction with the precision linear guide and can carry different types of pallets. The rack is arranged parallel to the precision linear guide, and the slide table is slidably mounted on the rack via gears. The servo motor drives the gears to mesh and roll on the rack via the reducer, thereby moving the slide table between the external and internal loading / unloading stations.

[0055] Specifically, a servo motor drives a slide table to the external loading / unloading station. The pallet to be measured is placed on the slide table manually or by a robotic arm. Then, the servo motor drives the slide table to the internal loading / unloading station, where the transfer mechanism 5 removes the pallet from the slide table. Once the pallet has passed measurement, the transfer mechanism 5 transfers the qualified pallet to the slide table located at the internal loading / unloading station. The servo motor then drives the slide table to the external loading / unloading station, where the qualified pallet is finally removed manually or by a robotic arm, completing the automatic pallet loading / unloading process.

[0056] It should be noted that the loading / unloading mechanism 1 in this embodiment also includes a limiting mechanism and limit switches. The limiting mechanism is used to limit the sliding displacement of the slide table on the precision linear guide rail, so as to accurately control the slide table to slide to the external and internal loading / unloading stations. The limit switches are used to limit the extreme sliding displacement of the slide table on the precision linear guide rail, preventing the slide table from sliding off the precision linear guide rail and improving the safety of the loading / unloading mechanism 1. In addition, the slide table has multiple pallet stations, each of which can hold and fix one pallet. Each loading station is equipped with a pallet detection sensor to detect in real time whether the corresponding loading station is holding a pallet, so as to rationally plan the use of each loading station. At the same time, the loading station has a positioning guide pin to guide the placement and installation of the pallet, so as to ensure the positioning accuracy of the pallet and enable the transfer mechanism 5 to accurately grab the pallet each time. Since the limiting mechanism and limit switches are existing technologies, they will not be described in detail here.

[0057] After the transfer mechanism 5 removes the pallet to be measured from the internal loading and unloading station, it moves the pallet to the cleaning mechanism 2 to clean the surface of the pallet to be measured (mainly cleaning the bearing surface and mounting surface of the pallet). This prevents dust and other impurities on the pallet surface from affecting the subsequent measurement results, which helps to improve the measurement accuracy and avoid misjudgment.

[0058] Specifically, such as Figure 2As shown, the cleaning mechanism 2 includes a cleaning support 21, a solution tank 22, a cleaning head 23, and a cleaning drive. The cleaning support 21 has a cleaning station. The solution tank 22 is located on one side of the cleaning support 21 and contains cleaning solution. The transfer mechanism 5 is detachably connected to the cleaning head 23 to drive the cleaning head 23 to pick up the cleaning solution in the solution tank 22 and install the cleaning head 23 at the cleaning station. The cleaning drive is located on the cleaning support 21 and is driven by the cleaning head 23 to drive the cleaning head 23 to rotate relative to the cleaning station to clean the tray to be measured. The cleaning drive is a motor, which is installed below the cleaning station of the cleaning support 21. The transfer mechanism 5 grips or releases the cleaning head 23 through a clamp to achieve a detachable connection with the cleaning head 23. When the transfer mechanism 5 installs the cleaning head 23 at the cleaning station, the output end of the motor can be driven by the cleaning head 23 to drive the cleaning head 23, which has been dipped in cleaning solution, to rotate. Then, the transfer mechanism 5 moves the pallet removed from the internal loading and unloading station to the cleaning head 23 for cleaning to improve the cleaning quality of the pallet. The aforementioned cleaning agent can clean surface impurities of the pallet without causing surface damage. It should be noted that during the cleaning process, the transfer mechanism 5 uses the coordinated movement of various joints to drive the pallet to perform multi-angle flipping and other actions relative to the cleaning head 23 to increase the cleaning range of the pallet.

[0059] Furthermore, the cleaning support 21 also has a drying station, and the transfer mechanism 5 can sequentially transfer the pallet from the internal loading / unloading station to the cleaning station and the drying station. The cleaning mechanism 2 also includes a second air blowing assembly 24 located at the drying station, which can dry the cleaned pallet transferred to the drying station. The second air blowing assembly 24 includes an air source and an air pipe. The air source can generate compressed air, and the outlet of the air source is connected to the air pipe. A nozzle is installed at the end of the air pipe. The air pipe blows compressed air through the nozzle to the drying station to dry the cleaning agent on the surface of the pallet located at the drying station, avoiding affecting the subsequent measurement results of the pallet and further improving the measurement accuracy.

[0060] like Figure 2As shown, the solution tank 22 includes a tank body 221, a tank cover 222, and a switch drive 223. The tank body 221 is disposed on one side of the cleaning bracket 21, and contains cleaning solution with an opening for the cleaning head 23 to enter and exit. The tank cover 222 is movably disposed at the opening of the tank body 221. The switch drive 223 is disposed on the tank body 221 and is kinetically connected to the tank cover 222 to drive the tank body 221 to open or close the opening. Closing the opening of the tank body 221 by the tank cover 222 prevents the cleaning solution inside the tank body 221 from being contaminated by external impurities and reduces the evaporation of the cleaning solution. In this embodiment, the switch drive 223 is a cylinder, which has a simple structure and is easy to install and maintain. In other embodiments, the switch drive 223 can also be a motor or a hydraulic cylinder, etc. The cover 222 is flipped or moved by the switch drive 223, so that the cover 222 can automatically open or close the opening of the box 221 without manual operation, which improves the automation level of the cleaning mechanism 2 and improves the cleaning efficiency.

[0061] Specifically, after the transfer mechanism 5 is connected to the cleaning head 23, the switch drive 223 drives the cover 222 to open the opening of the housing 221. The transfer mechanism 5 drives the cleaning head 23 to extend into the housing 221 from the opening, dip it in cleaning fluid, and then extend it out of the opening to install the cleaning head 23 at the cleaning station. Finally, the switch drive 223 drives the cover 222 to close the opening of the housing 221.

[0062] like Figure 3 As shown, the cleaning mechanism 2 also includes a storage rack 25, on which various types of cleaning heads 23 are placed, allowing the transfer mechanism 5 to select the appropriate cleaning head 23 according to the different types of pallets. For example, the transfer mechanism 5 can use its own installed detection components (such as image sensors) to detect the type of pallet and the type of cleaning head 23, and match the appropriate cleaning head 23 model according to the type of pallet. Since the detection components of the transfer mechanism 5 are existing technology, the structure and working principle of the detection components will not be described in detail.

[0063] It should be noted that the buffer mechanism 3 includes a buffer rack and clamping tools. The buffer rack has multiple buffer stations; some buffer stations are used to store cleaned trays, and others are used to store clamping tools. These clamping tools need to be installed inside the measuring mechanism 4 to clamp and position the trays to be measured. Inventory detection sensors are installed at each buffer station to monitor the storage status of trays and clamping tools in real time. Each buffer station is also equipped with guide positioning pins to ensure accurate positioning of trays and clamping tools during each retrieval and placement, facilitating precise gripping of trays and clamping tools by the transfer mechanism 5. The buffer rack adopts a structure of stacked single-layer detachable racks, allowing for flexible increases or decreases in the number of single-layer detachable racks according to usage requirements, thus improving the versatility of the buffer rack.

[0064] After the pallet is cleaned, the transfer mechanism 5 transfers the pallet to an empty buffer station on the buffer rack. Then, the transfer mechanism 5 transfers the clamping tool on the buffer rack to the measuring mechanism 4 for automatic installation. Finally, the transfer mechanism 5 transfers the pallet from the buffer rack to the clamping tool, completing the preparation work before pallet measurement. In this embodiment, the clamping tool has different models depending on the type of pallet to achieve precise clamping. The clamping tool can clamp and release the pallet using electric, pneumatic, or hydraulic drives. Since the clamping tool is existing technology, its structure and working process will not be described in detail.

[0065] The measuring mechanism 4 in this embodiment can detect the flatness of the pallet's bearing surface and mounting surface using existing measuring tools, and determine whether the pallet is qualified based on the measurement results. Since the measuring mechanism 4 can use the measuring tools used in manual measurement, the specific structure and working process of the measuring mechanism 4 will not be described in detail.

[0066] After the pallet measurement is completed, based on the measurement results, the transfer mechanism 5 transfers the qualified pallets to the internal loading and unloading station, and the loading and unloading mechanism 1 transfers the qualified pallets from the internal loading and unloading station to the external loading and unloading station to complete the pallet unloading process. At the same time, the transfer mechanism 5 removes the unqualified pallets from the measuring mechanism 4 for manual adjustment or correction, and then remeasures them.

[0067] like Figure 4 As shown, the automatic pallet measuring equipment also includes an adjustment mechanism 6, which can move between an external adjustment station and an internal receiving station to transfer pallets that fail measurement at the internal receiving station to the external adjustment station, and to transfer adjusted pallets from the external adjustment station to the internal receiving station. The transfer mechanism 5 can transfer pallets that fail measurement to the internal receiving station, and to transfer adjusted pallets from the internal receiving station to the measuring mechanism 4 for remeasurement. The workbench has an external adjustment station and an internal receiving station. The adjustment mechanism 6 transfers non-conforming pallets from the internal receiving station to the external adjustment station, allowing personnel outside the workbench to readjust or correct the non-conforming pallets, and then the adjusted pallets are placed back onto the adjustment mechanism 6 located at the external adjustment station. The pallet adjustment and correction operations are existing technology and will not be described in detail here.

[0068] Specifically, the adjustment mechanism 6 includes an adjustment bracket 61, an adjustment platform 62, and an adjustment drive component 63. The adjustment bracket 61 has an external adjustment station and an internal receiving station. The adjustment platform 62 is slidably mounted on the adjustment bracket 61 and can support the tray to be measured. The adjustment drive component 63 is drively connected to the adjustment platform 62 to drive the adjustment platform 62 to move between the external adjustment station and the internal receiving station. In this embodiment, the adjustment drive component 63 is a KK module, which has a simple structure and is easy to install and maintain. In other embodiments, the adjustment drive component 63 can also be a motor or other components.

[0069] like Figure 4 As shown, the adjustment mechanism 6 also includes positioning posts 64 and support posts 65. The positioning posts 64 are disposed on the adjustment platform 62, and the pallet has corresponding positioning holes through which it fits onto the positioning posts 64. At least two support posts 65 are arranged circumferentially around the positioning posts 64, and the at least two support posts 65 can jointly support the pallet. Through the cooperation between the positioning posts 64 and the positioning holes of the pallet, the pallet can be accurately placed on the adjustment platform 62, so as to ensure that the transfer mechanism 5 can accurately pick up and place the pallet. In this embodiment, the support posts 65 have three models, and each model has four support posts 65. The four support posts 65 of the same model are arranged in a positive direction around the positioning post 64. The height of the three models of support posts 65 increases sequentially in the direction away from the positioning post 64, so as to achieve stable support for three different types of pallets and avoid interference between different models of support posts 65. The height of the three models of support posts 65 needs to be adjusted adaptively according to the type of pallet, and is not specifically limited here. In other embodiments, the model and quantity of the positioning posts 64 can be flexibly adjusted according to requirements, and no specific limitation is made here.

[0070] Furthermore, the adjustment mechanism 6 also includes a fixing component 66, which is slidably disposed on the adjustment table 62 and has a locking position that abuts the pallet against the positioning post 64 and an unlocking position that moves away from the pallet on the adjustment table 62. By fixing the pallet against the positioning post 64 with the fixing component 66, the pallet is securely placed on the adjustment table 62, preventing the pallet from tilting or falling when the adjustment table 62 moves between the external adjustment station and the internal receiving station.

[0071] In this embodiment, the fixing component 66 consists of a cylinder and a top plate. The cylinder is driven to the top plate to move the top plate closer to or further away from the tray on the adjusting platform 62. When the top plate is in the locked position, it presses the tray against the adjusting platform 62, locking the tray onto the positioning post 64. When the top plate is in the unlocked position, it disengages from the top of the tray on the adjusting platform 62, allowing the tray to be freely placed and removed along the positioning post 64 on the adjusting platform 62. In other embodiments, the fixing component 66 can also be a combination of a motor and a top plate.

[0072] Furthermore, the adjustment mechanism 6 also includes a first air-blowing assembly 67 disposed on the adjustment platform 62. The first air-blowing assembly 67 can blow air onto the support column 65 to clean the support column 65. In this embodiment, the second air-blowing assembly 24 has the same structure as the first air-blowing assembly 67, and both can blow compressed air onto the tray. Multiple first air-blowing assemblies 67 are evenly distributed on the adjustment platform 62. When the transfer mechanism 5 transfers a defective tray to the top of the adjustment platform 62, the second air-blowing assembly 24 can blow compressed air onto the support column 65 to clean the support column 65, preventing the support column 65 from scratching the surface of the tray (especially the mounting surface of the tray), thus improving the protection of the tray.

[0073] like Figure 4 As shown, the adjustment mechanism 6 also includes a measuring sensor 68 mounted on the adjustment table 62 to detect whether a pallet to be measured is supported on the adjustment table 62 located at the internal receiving station. When the transfer mechanism 5 transfers an unqualified pallet to the adjustment table 62, the measuring sensor 68 detects in advance that there is no pallet to be measured on the adjustment table 62. If there is no pallet on the adjustment table 62, the transfer mechanism 5 transfers the unqualified pallet to the adjustment table 62; if a pallet to be measured is detected on the adjustment table 62, the transfer mechanism 5 needs to wait until the measuring sensor 68 detects that there is no pallet to be measured on the adjustment table 62 before transferring the unqualified pallet to the adjustment table 62.

[0074] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
