[0037] Exemplarily, the grabbing mobile device 5 can use an existing manipulator, vacuum suction cup, etc. For example, the vacuum suction cup can be installed on the movable end of the three-axis gantry platform, and the vacuum suction cup can be used to suck each accessory and move it to the magnetic core on the tray 22 for assembly. The working and control methods of the vacuum suction cup belong to the existing technology.

The equipment platform 1 is provided with a pressing component 9 and a flipping component 10 in sequence along the conveying direction of the main conveyor belt 8.

[0039] Exemplarily, the main conveyor belt 8 can be a non-powered roller conveyor belt, which can be installed on the equipment platform 1 by conventional means such as existing brackets, which will not be described here. Specifically, the roller conveyor belt can be installed on the equipment platform 1 at an angle, and the downward end of the roller conveyor belt is set toward the feed port of the translation transmission component 2, so that the tray 22 after the patch is completed can be moved to the pressing component 9 and the flipping component 10 in turn under the action of its own gravity, which reduces the structural complexity of the main conveyor belt 8, is beneficial to energy saving and environmental protection, and is also beneficial to reducing the use cost of this glue patch equipment.

[0040] In actual application, by arranging the glue dispensing and patching mechanism and the assembly and clamping mechanism in parallel on the equipment platform 1, and arranging the translation transmission component 2 in the glue dispensing and patching mechanism and the main conveyor belt 8 in the assembly and clamping mechanism end to end relative to each other, the tray 22 can be recycled. That is, after the magnetic cores on the tray 22 are completed and compacted, the operator can remove the magnetic cores on the tray 22 and put in new magnetic cores, and conveniently put the tray 22 back into the translation transmission component 2 for gluing and patching the next batch of magnetic cores, which reduces the operating difficulty of the operator and is conducive to improving the processing efficiency of the magnetic cores.

[0041] Preferably, the tray 22 is provided with a positioning groove 39 that matches the magnetic core, and a plurality of through holes 38 are provided at positions corresponding to the positioning groove 39 below the tray 22, and each through hole 38 is connected to the positioning groove 39; the pressing assembly 9 includes a pressing member 35 provided corresponding to the through hole 38, and a lifting column 36 for driving each pressing member 35 to rise and fall. Exemplarily, four, six or more through holes 38 can be evenly arranged along the circumference of the positioning groove 39, and correspondingly, the pressing members 35 and the through holes 38 are arranged one by one, the fixed end of the lifting column 36 can be installed on the equipment platform 1 by conventional means such as screws, and the telescopic end can also be connected to the pressing member 35 by conventional means such as screws, and the lifting column 36 can adopt existing equipment such as existing pressing cylinders to drive the pressing member 35 to rise and fall, which will not be described here.

[0042] In actual application, the positioning groove 39 on the tray 22 can be used to accommodate and limit the magnetic core, and by providing multiple through holes 38 and the pressing piece 35, it is helpful to improve the uniformity of the pressing piece 35 when pressing down, thereby improving the bonding and fixing effect of the accessories on the magnetic core.

[0043] Preferably, limit grooves 37 are correspondingly provided on the left and right sides of the tray 22, and limit components 13 that can cooperate with the limit grooves 37 are provided at the positions on the equipment platform 1 corresponding to the left and right sides of the translational transmission component 2; the limit component 13 includes a horizontally arranged telescopic rod, the length direction of the telescopic rod is perpendicular to the transmission direction of the translational transmission component 2, the fixed end of the telescopic rod is arranged on the equipment platform 1, and the telescopic end is provided with a connector that can cooperate with the limit groove 37.

[0044] Exemplarily, the telescopic rod can adopt an existing positioning cylinder, and the fixed end of the positioning cylinder is installed on the equipment platform 1 by conventional means such as screws, and the telescopic end and the connector can also be connected by conventional means such as screws. In actual use, the telescopic rod can be set according to the position of glue dispensing and patch patching during the translation transmission process. When glue dispensing and patch patching are required, the telescopic rod is used to drive the connector to be inserted into the limit groove 37 on the tray 22 to achieve the limit fixation of the tray 22 and ensure the processing accuracy of glue dispensing and patch patching. Those skilled in the art can arrange it according to actual needs, which will not be repeated here. In addition, to facilitate the assembly and picking of the tray 22, structures such as handles and positioning pins can also be installed on the edge of the tray 22. Those skilled in the art can set it according to actual needs, which will not be repeated here.

[0045] Preferably, the positions on the equipment platform 1 corresponding to the translation transmission component 2 and the main conveyor belt 8 are provided with a blocking cylinder 25 for blocking and limiting the pallet 22. Exemplarily, the fixed end of the blocking cylinder 25 can be installed on the equipment platform 1 by conventional means such as screws, and the telescopic end can be installed with a blocking wheel, and the blocking wheel can be installed on the telescopic end by conventional means such as a rotating shaft to realize the rotation installation of the blocking wheel. By setting the blocking cylinder 25, the pallet 22 can be blocked, so that the operator and the equipment can perform corresponding operations. In actual use, the blocking cylinder 25 can be set for the position of glue dispensing and patch during the translation process, and the blocking cylinder 25 can also be set for the feed end and the pressing component 9 during the conveying process of the main conveyor belt 8 to achieve the blocking and limiting of the pallet 22, so as to realize the positioning of the pallet 22. Those skilled in the art can also arrange it according to actual needs, which will not be repeated here.

[0046] Preferably, a slot 23 is provided under the tray 22, and four slots 23 are evenly arranged around the tray 22. The flip assembly 10 includes a flip bin 30, and a driver 33 for driving the flip bin 30 to rotate is provided on the equipment platform 1; the flip bin 30 is provided with a receiving hole for accommodating a group of trays 22, and the tray 22 group includes two trays 22 arranged opposite to each other; claw members 31 that can cooperate with the slots 23 are provided above and below the flip bin 30, and a telescopic cylinder 32 for driving the claw member 31 to cooperate with the slots 23 is provided on the flip bin 30.

[0047] Exemplarily, the claw member 31 is an L-shaped structural member, and the middle part of the claw member can be rotatably installed on the flip bin 30 by conventional means such as a rotating shaft. The horizontal end of the claw member 31 is arranged toward the receiving hole of the flip bin 30, and is fixed with a claw part that can cooperate with the slot 23, and the vertical end is rotatably connected to the telescopic end of the telescopic cylinder 32. By using the claw part to cooperate with the slot 23, the tray 22 can be limited. At the same time, the upper and lower groups of claw members 31 are used to clamp and fix the tray 22, which can ensure the stability of the tray 22 during the flipping process and prevent the tray 22 from falling out of the flip bin 30. In addition, those skilled in the art can also select claw members 31 of other structures and corresponding installation methods according to actual needs, so that the telescopic cylinder 32 drives the claw member 31 to move, so that the claw member 31 can cooperate with the slot 23 on the tray 22.

[0048] In actual application, the telescopic cylinder 32 can adopt an existing telescopic cylinder, the fixed end of the telescopic cylinder can be rotatably mounted on the flip bin 30 by a conventional method such as a rotating shaft, and the telescopic end can also be rotatably connected to the claw member 31 by a conventional method such as a rotating shaft. The claw member 31 can be driven to rotate by the telescopic cylinder extension, thereby achieving the clamping of the tray 22 group.

[0049] Specifically, when the tray 22 group falls into the flip bin 30, the claw part on the claw member 31 cooperates with the slot 23 to achieve the initial positioning of the tray 22 group, and the tray 22 group is limited in the flip bin 30. Then, the telescopic cylinder continues to extend, which can drive the upper and lower claw members 31 to clamp and fix the tray 22 group. At this time, the driver 33 can be used to drive the flip bin 30 to flip, so as to achieve the flipping of the tray 22 and the magnetic core in the tray 22. Among them, the driver 33 can adopt an existing servo motor or flip motor, etc. The fixed end of the driver 33 can be installed on the equipment platform 1 by conventional means such as screws, and the telescopic end can be connected to the flip bin 30 by conventional means such as screws. Those skilled in the art can also select other suitable drivers 33 and connection methods according to actual needs to achieve the flipping of the flip bin 30, which will not be repeated here.

[0050] In addition, rollers 34 may be installed on the inner wall of the turning bin 30, and multiple rollers 34 are arranged at intervals. Each roller 34 can be rotatably installed on the turning bin 30 by conventional means such as a rotating shaft, so as to facilitate the tray 22 group to enter and move out of the turning bin 30. After the turning bin 30 is turned over, the claw member 31 can be shortened by the telescopic cylinder to reset, and the clamping fixation of the tray 22 group can be released. The tray 22 group can be moved out of the turning bin 30 under the action of its own gravity and the guidance of the rollers 34, and then the driver 33 is used again to drive the turning bin 30 to rotate and reset, so that it can be used for the turning operation of the next tray 22 group.

[0051] Optionally, the translation transmission component 2 can use an existing translation cylinder 24, the fixed end of the translation cylinder 24 is installed on the equipment platform 1 by conventional means such as screws, and the movable end can be fixedly installed with a carrier plate 14 for carrying the tray 22. Exemplarily, a clamping member 15 that can cooperate with the card slot 23 is provided on the carrier plate 14, and a mounting hole for installing the clamping member 15 is provided on the carrier plate 14. The clamping member 15 passes through the mounting hole below and is rotatably installed on the carrier plate 14 by conventional means such as a rotating shaft, and a bearing seat that cooperates with the rotating shaft is fixedly installed on the carrier plate 14. Among them, the air supply and control methods of the translation cylinder 24 are both existing technologies, and those skilled in the art can also select other suitable translation transmission components 2 according to actual needs to realize the movement of the carrier plate 14 and the tray 22 thereon, which will not be repeated here.

[0052] In actual use, a fixed counterweight 16 can be installed under the clamping member 15 to realize that the clamping member 15 is driven to rotate and reset under the action of the counterweight 16. In this way, when the operator pushes the front end of the tray 22 into the carrier plate 14, the clamping member 15 can be driven to rotate and be stored in the installation hole, so that the tray 22 can enter the translation transmission assembly 2. At this time, the lower end of the clamping member 15 can also drive the counterweight 16 to lift and store energy.

[0053] When the slot 23 on the rear end of the tray 22 moves to the clip 15, the clip 15 can be rotated and reset and moved out of the mounting hole under the gravity of the counterweight 16. At this time, the clip 15 can support the inner wall of the mounting hole and cooperate with the slot 23 to achieve horizontal limitation of the tray 22, making it convenient for the translation cylinder 24 to drive the tray 22 to the next workstation through the supporting plate 14. The operation is very simple, which is beneficial to reduce the difficulty of loading the tray 22 and improve the stability of the translation transmission component 2 when driving the tray 22 to move.

[0054] Preferably, the detection component 3 includes a height measuring instrument 17 and a power-on detector 18, the measuring terminal 19 of the height measuring instrument 17 is provided with an insulating block 21, the insulating block 21 is provided with a connecting terminal 20, the connecting terminal 20 is arranged parallel to the measuring terminal 19 and spaced apart, and the positive and negative connectors of the power-on detector 18 are respectively connected to the connecting terminal 20 and the measuring terminal 19.

[0055] Exemplarily, the height measuring instrument 17 can be an existing contact height measuring instrument 17 or an electronic height measuring instrument, etc. The insulating block 21 can be fixed on the measuring terminal 19 of the height measuring instrument 17 by conventional means such as screws or adhesives, the insulating block 21 can be made of insulating materials such as rubber or plastic, and the terminal 20 can also be fixed on the insulating block 21 by conventional means such as screws or adhesives.

[0056] In actual application, the measuring terminal 19 and the wiring terminal 20 can be connected to the positive and negative terminals of the existing power-on detector 18 through wires. The power-on detector 18 can use existing resistance detection equipment, current detection equipment or multimeter, etc. to realize the detection of the power-on performance of the magnetic core surface. Technical personnel in this field can select appropriate detection equipment according to actual needs, which will not be repeated here.

[0057] Specifically, when the measuring terminal 19 measures the height of the magnetic core, the measuring terminal 19 and the wiring terminal 20 will both contact the surface of the magnetic core. At this time, a loop will be formed between the measuring terminal 19 and the wiring terminal 20 and the power-on detector 18. Since the magnetic core is generally conductive, a relatively small current will be generated when the loop is energized. By detecting the current, it can be determined that the measuring terminal 19 and the wiring terminal 20 are in contact with the surface of the magnetic core. When the measuring terminal 19 and the wiring terminal 20 are in contact with the surface of the air gap sheet pasted on the magnetic core, since the air gap sheet is insulated, a loop cannot be formed, so no current is generated when power is turned on. By detecting the insulation performance of the magnetic core surface, it is possible to detect whether the magnetic core has completed the air gap sheet pasting, thereby facilitating the subsequent dispensing and patch operations according to the pasting status of the air gap sheet, which is conducive to improving the automation level of such glue-coating patch equipment.

[0058] Preferably, a conveyor belt 11 for conveying pallets 22 is further provided at a position on the equipment platform 1 corresponding to below the main conveyor belt 8, and the feed end of the conveyor belt 11 is provided corresponding to the discharge end of the main conveyor belt 8, and the discharge end of the conveyor belt 11 is provided corresponding to the feed end of the main conveyor belt 8. Exemplarily, the conveyor belt 11 can adopt an existing electric conveyor belt 11, and is installed and fixed on the equipment platform 1 by conventional means such as a bracket. By arranging the conveyor belt 11 below the main conveyor belt 8, it is helpful to reduce the overall volume of such equipment, and the conveyor belt 11 can be used to convey empty pallets 22, so that the operator can buckle the empty pallet 22 on the pallet 22 carrying the magnetic core to obtain a pallet 22 group.

[0059] In actual use, the tray 22 transmitted through the transmission component 7 carries a magnetic core, and a tray 22 group can be formed by snapping an empty tray 22 onto a tray 22. The tray 22 group can pass through the pressing component 9 and the flipping component 10 in turn to achieve the pressing of the patch and the flipping of the magnetic core.

[0060] Preferably, the outgoing component 7 includes an upward lifting cylinder 26 and an outgoing conveyor belt 29, one end of the outgoing conveyor belt 29 is arranged toward the discharge end of the translation transmission component 2, and the other end is arranged toward the feed end of the main conveyor belt 8. The telescopic end of the upward lifting cylinder 26 is provided with a guide plate 27 for lifting, and the fixed end is arranged on the equipment platform 1. The guide plate 27 is arranged at an angle, and the downward end of the guide plate 27 is arranged toward the outgoing conveyor belt 29, and a plurality of guide wheels 28 are rotatably mounted on the guide plate 27.

[0061] Exemplarily, the fixed end of the lifting cylinder 26 can be mounted on the equipment platform 1 by conventional means such as screws, the guide plate 27 can also be mounted on the telescopic end of the lifting cylinder 26 by conventional means such as screws, and the guide wheel 28 can be rotatably mounted on the guide plate 27 by conventional means such as a rotating shaft. By adopting an inclined guide plate 27 and arranging a plurality of rotatable guide wheels 28 on the guide plate 27, the tray 22 can move along the guide plate 27 under the action of its own gravity during the process of being lifted by the guide plate 27, which reduces the difficulty of transferring the tray 22 and helps to reduce the complexity of the equipment structure.

[0062] In actual application, the translation transmission assembly 2 can move the tray 22 of the magnetic core to the guide plate 27, and then use the lifting cylinder 26 to drive the guide plate 27 to lift the tray 22 upward, so that the tray 22 can move along the guide plate 27 to the outgoing conveyor belt 29, and finally move to the main conveyor belt 8 through the outgoing conveyor belt 29 to buckle the empty tray 22. Among them, the outgoing conveyor belt 29 can also adopt the existing non-powered roller conveyor belt, and be installed and fixed on the equipment platform 1 by conventional means such as a bracket.

[0063] Preferably, an incoming conveyor belt 12 is provided at a position corresponding to the discharge end of the main conveyor belt 8 on the equipment platform 1, one end of the incoming conveyor belt 12 is arranged toward the discharge end of the main conveyor belt 8, and the other end is arranged toward the feed end of the translation conveyor assembly 2. Exemplarily, the incoming conveyor belt 12 can also adopt an existing non-powered roller conveyor belt, and be installed and fixed on the equipment platform 1 by conventional means such as a bracket. By providing the incoming conveyor belt 12, the operator can conveniently push the flipped tray 22 back into the translation conveyor assembly 2 for subsequent dispensing and patching operations, which is conducive to reducing the operating difficulty of the operator.

[0064] Preferably, the dispensing assembly 4 includes a dispensing device and a three-axis gantry platform, the fixed end of the three-axis gantry platform is arranged on the device platform 1, and the dispensing device is arranged on the movable end of the three-axis gantry platform. Specifically, the dispensing device and the three-axis gantry platform can both use existing equipment to achieve the dispensing of the magnetic core. Those skilled in the art can make a choice according to actual needs, which will not be repeated here. By installing the dispensing device on the three-axis gantry platform, it is beneficial to improve the freedom of movement of the dispensing device, thereby ensuring the uniformity of the dispensing.

[0065] Based on the above automatic glue coating and patching equipment, the following glue coating and patching methods can be adopted:

[0066] Step 101: Place the magnetic core into the positioning groove of the tray, and place the tray with the magnetic core into the feed end of the translation conveyor assembly, and use the translation conveyor assembly to drive the tray to move.

[0067] Step 102: Use the detection component to detect the height and surface of the magnetic core, and select the preset dispensing program and patch program according to the detection results.

[0068] Specifically, the height of the magnetic core can be measured by the height measuring instrument on the detection component, and the height of the glue dispensing can be adjusted according to the height of the magnetic core for glue application. The power-on detector can be used to measure whether the surface of the magnetic core fits the air gap sheet, so as to select the accessories that need to be pasted later (such as aluminum sheet, air gap sheet, magnetic sheet, etc.) for patch pasting. Among them, the preset glue dispensing program and patch program can be adjusted according to actual needs, and those skilled in the art can continue to design according to the process, which will not be repeated here.

[0069] Step 103: Use the translational transport component to move the tray to the glue dispensing component, and use the glue dispensing component to perform glue dispensing.

[0070] Step 104: Use the translational transport component to move the tray to the patch component, use the grabbing mobile device to grab the accessories on the accessory feeding device, and move the accessories to the magnetic core for patching.

[0071] Step 105: Use the translation transfer assembly to move the pallet to the outgoing assembly, and use the outgoing assembly to move the pallet onto the main conveyor belt.

[0072] Specifically, after the pallet moves to the lifting cylinder of the outgoing assembly, the lifting cylinder drives the guide plate to lift the pallet, and the pallet can move along the outgoing output belt to the main conveyor belt.

[0073] Step 106: buckle the empty pallet onto the pallet with the magnetic core on the main conveyor belt to obtain a pallet group, and move the pallet group along the main conveyor belt to the pressing assembly.

[0074] Step 107: After the magnetic core and accessories are pressed tightly by the pressing assembly, the tray assembly is moved along the main conveyor belt to the flip assembly.

[0075] Step 108: Use the turning assembly to turn over the tray assembly.

[0076] Specifically, the downward pressure cylinder returns to the initial position, the blocking cylinder returns to the original position, and the pallet group continues to move to the flip assembly. After the pallet group reaches the flip assembly, the flip bin drives the pallet to flip 180°, and then the pallet group is partially transferred out of the flip bin. After the operator completely pulls the pallet out of the flip bin, the flip bin returns to the initial position. The operator removes the pallet above the pulled-out pallet group and puts it on the conveyor belt below, and transfers the empty pallet to the feed end of the main conveyor belt for the operator to use. At the same time, the operator can push the pallet into the feed end of the translation conveyor assembly again to carry out the next step of dispensing and patching operations.

[0077] For example, when attaching air gap sheets and magnetic sheets to the middle column of the magnetic core, when the tray reaches the flip assembly, the flip bin does not move, and the tray is directly transferred out through the flip assembly. The operator pushes the tray into the equipment entrance again, enters the glue dispensing module, and performs the next step of glue dispensing until all the aluminum sheets or air gap sheets / magnetic sheets required on the magnetic core are attached. Those skilled in the art can select the appropriate operation mode according to actual needs, and the entire assembly of the magnetic core can be completed by sending the tray with the magnetic core into this glue coating and patching equipment multiple times, which is very simple to operate.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
