[0038] Please refer to Figures 1 to 8 As shown, the present invention proposes a loading device 100, which is used to transfer the circuit board on the material tray to the carrier tray. The loading device 100 includes a machine 1, a transmission device 2, a loading device 3, an unloading device 4, a first transfer device 5 and a second transfer device 6. The transmission device 2 is arranged on the machine 1, and is provided with a transmission channel 21 and a placement position 22 located on the transmission channel 21, and the transmission channel 21 is used to transfer the carrier tray; the loading device 3 is arranged on the machine 1, and the loading device 3 is used to load the material trays with circuit boards in a stacked arrangement; the unloading device 4 is arranged on the machine 1, and the unloading device 4 is used to unload the stacked empty material trays; the first transfer device 5 includes a first transfer component and a first adsorption component 55 arranged on the machine 1, the first adsorption component 55 is used to adsorb or release the circuit board, and the first transfer component drives the first adsorption component 55 to move between the loading device 3 and the placement position 22; the second transfer device 6 is arranged on the machine 1, and the second transfer device 6 is used to transfer the empty material tray from the loading device 3 to the unloading device 4.

[0039] In this embodiment, the transmission device 2 is provided with a transmission channel 21, and the two ends of the transmission channel 21 can be connected to the upstream equipment and the downstream equipment in the circuit board processing line respectively. The empty tray in the upstream equipment is transmitted to the placement position 22 of the transmission channel 21 via the transmission channel 21, and the loading device 3 loads the stacked trays with circuit boards to the loading position 312. The first transfer component drives the first adsorption component 55 to approach the loading device 3, and the first adsorption component 55 adsorbs the circuit boards in the tray. Then, the first transfer component drives the first adsorption component 55 to approach the placement position 22, and the first adsorption component 55 puts the circuit board into the tray located at the placement position 22. The transmission channel 21 transfers the tray with circuit boards to the downstream equipment, and the downstream equipment performs subsequent processing on the circuit boards. The empty trays in the loading device 3 are transferred to the unloading device 4 by the second transfer device 6, and the unloading device 4 stacks and unloads them. It can be understood that the material tray is the carrier of the circuit board during transportation, and the carrier tray is the carrier of the circuit board on the production line. The loading device 100 can realize the automatic transfer of the circuit board from the material tray to the carrier tray, which greatly improves the efficiency of loading the circuit board to the production line and saves labor costs.

[0040] In actual implementation, both the material tray and the carrier tray are provided with placement grooves for limiting the placement of the circuit board. The first adsorption member 55 adsorbs the circuit board in a vacuum adsorption manner.

[0041] In one embodiment of the present invention, Figure 2 , Figures 4 to 6 As shown, the feeding device 3 includes a feeding enclosure 31, a feeding drive 32 and a feeding platform 33. The feeding enclosure 31 is connected to the machine 1. The feeding enclosure 31 encloses a feeding channel 311. The feeding channel 311 is provided with a feeding position 312 corresponding to the first transfer device 5. The feeding drive 32 is provided in the feeding channel 311. The feeding platform 33 is connected to the output end of the feeding drive 32. The feeding platform 33 is provided with a plurality of positioning protrusions 331 arranged at intervals. The feeding drive 32 is used to drive the feeding platform 33 to drive the material tray carrying the circuit board to reach the feeding position The unloading device 4 comprises an unloading enclosure 41, an unloading driving member 42 and an unloading platform 43. The unloading enclosure 41 is connected to the machine platform 1. The unloading enclosure 41 encloses a unloading channel 411. The unloading channel 411 is provided with an unloading position 412 corresponding to the second transfer device 6. The unloading driving member 42 is provided in the unloading channel 411. The unloading platform 43 is connected to the output end of the unloading driving member 42. The unloading driving member 42 is used to drive the unloading platform 43 to drive the empty material tray to reach the unloading position 412.

[0042] In this embodiment, the feeding enclosure 31 encloses a feeding channel 311, which is arranged vertically with the table top of the machine 1 and connected with the table top of the machine 1. The feeding drive 32 and the feeding platform 33 are arranged in the feeding channel 311, and the feeding platform 33 is connected to the output end of the feeding drive 32. During the feeding process of the tray, the stack of trays loaded with circuit boards is placed on the feeding platform 33, and the feeding drive 32 drives the feeding platform 33 to drive the tray stack to move along the feeding channel 311 toward the machine 1. When the uppermost tray of the tray stack reaches the feeding position 312, the feeding drive 32 stops running, and the first transfer device 5 transfers the circuit boards in the uppermost tray. After the circuit boards in the uppermost tray are transferred, the second transfer device 6 transfers the uppermost empty tray and transfers it to the unloading device 4. After the top empty tray is transferred, the loading drive 32 drives the loading platform 33 to drive the tray stack to continue to move upward until the top tray with circuit boards in the tray stack reaches the loading position 312. The first transfer device 5 transfers the circuit boards, and the second transfer device 6 transfers the empty trays. The above steps are repeated until the tray stack is loaded. When a tray stack with circuit boards is loaded, another tray stack with circuit boards is manually replenished. In this way, there is no need to manually replenish trays with circuit boards frequently. The stacking and replenishment of trays effectively improves the replenishment efficiency, which indirectly improves the loading efficiency of circuit boards.

[0043] In this embodiment, the unloading enclosure 41 encloses a unloading channel 411, which is vertically arranged with the table top of the machine 1 and connected to the table top. The unloading drive 42 and the unloading table 43 are arranged in the unloading channel 411, and the unloading table 43 is connected to the output end of the unloading drive 42. During the unloading process of the material tray, the unloading drive 42 first drives the unloading platform 43 to the unloading position 412, and the second transfer device 6 transfers the empty material tray to the unloading platform 43, and the unloading drive 42 drives the unloading platform 43 to descend until the empty material tray reaches the unloading position 412, and then the second transfer device 6 continues to place the empty material tray on the upper surface of the empty material tray on the unloading platform 43, and the unloading drive 42 drives the unloading platform 43 to descend again until the uppermost material tray on the unloading platform 43 reaches the unloading position 412, and the second transfer device 6 transfers the material tray to the unloading platform 43, and repeats the above steps until all the material trays on the loading platform 33 are transferred to the unloading platform 43 and placed in a stacked state on the unloading platform 43, and then while replenishing the stack of material trays loaded with circuit boards on the loading platform 33, the stack of empty material trays on the unloading platform 43 is taken down, and the unloading platform 43 is emptied to prepare for the placement of the next group of material tray stacks.

[0044] In actual implementation, the loading channel 311 and the unloading channel 411 are arranged at intervals; the loading enclosure 31 and the unloading enclosure 41 are both composed of steel sections and plates, and the unloading enclosure 41 is also provided with a guide plate corresponding to the unloading position 412, so that the material tray can smoothly enter the unloading channel 411. The loading drive 32 and the unloading drive 42 are composed of linear drive devices such as electric cylinders and rails or motors, screws and slide rails. The table top of the loading platform 33 is perpendicular to the driving direction of the loading drive 32, and the table top of the unloading platform 43 is perpendicular to the driving direction of the loading drive 32, which is not specifically limited here.

[0045] In one embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the loading device 3 also includes a loading transmission component 34 arranged on the machine 1, and the loading transmission component 34 is provided with a first transmission channel, and the first transmission channel is connected to the end of the loading channel 311 away from the loading position 312, and the extension direction of the first transmission channel is perpendicular to the extension direction of the loading channel 311.

[0046] In this embodiment, the loading transmission assembly 34 is provided with a first transmission channel connected to the loading channel 311, and the first transmission channel is connected to the end of the loading channel 311 away from the loading position 312. The transmission device 2, the first transfer device 5 and the second transfer device 6 are all arranged on the table of the machine 1. During the tray loading process, the loading drive 32 drives the loading platform 33 to descend into the first transmission channel. The worker can put the stacked trays carrying circuit boards into the first transmission channel from the end of the first transmission channel away from the loading channel 311. The loading transmission assembly 34 transfers the trays along the first transmission channel to the loading platform 33. Then, the loading drive 32 drives the loading platform 33 to rise to leave the first transmission channel and reach the loading position 312 through the loading channel 311, waiting for the first transfer device 5 and the second transfer device 6 to transfer the circuit boards and trays.

[0047] It can be understood that the loading device 3 and the unloading device 4 are arranged on the same side of the transmission device 2, and the operation side of the loading device 100 is generally located on the side of the transmission device 2 that is away from the loading device 3 and the unloading device 4. Therefore, the setting of the first transmission channel enables the operator to load the tray carrying the circuit board from the operation side of the loading device 100 to reduce the workload of the operator. At the same time, the end of the first transmission channel away from the loading channel 311 can also be directly connected to the conveying line of the tray to realize the automation of the tray loading.

[0048] In one embodiment of the present invention, Figure 4As shown, the loading transmission assembly 34 includes a plurality of loading transmission members 341, the first transmission channel includes a plurality of loading transmission sections 342, each loading transmission member 341 is provided with a loading transmission section 342, and each loading transmission section 342 is used to transmit a stack of material trays.

[0049] In this embodiment, the first transmission channel is divided into multiple loading transmission sections 342, each loading transmission section 342 is formed by a loading transmission member 341. When the first transmission component transmits the material tray stack, each loading transmission section 342 can hold a material tray stack. In this way, when the operator loads the material tray stack to the first transmission channel, multiple material tray stacks can be loaded at one time corresponding to the number of loading transmission sections 342, so as to reduce the operator's operation frequency. In this embodiment, each loading transmission member 341 can operate independently to control the distance between adjacent material tray stacks in the loading transmission channel 21 and ensure the stability of material tray loading.

[0050] It can be understood that the loading transmission section 342 close to the loading channel 311 needs to remain unloaded before the loading drive 32 drives the loading platform 33 to descend to the first transmission channel to avoid the stack of material trays blocking the movement of the loading platform 33, so the loading transmission member 341 runs intermittently. After the loading member drives the loading platform 33 to descend to the first transmission channel, the loading transmission member 341 transmits the material tray stack to the upper feeding channel 311 until a material tray stack reaches the loading transmission section 342 closest to the loading channel 311, and the loading transmission member 341 stops running. At this time, the loading platform 33 is located below the material tray stack, and the loading driving member 32 can drive the loading platform 33 to lift the material tray stack; when a material tray stack is lifted by the loading platform 33, the operator can replenish the material tray stack to the loading transmission section 342 farthest from the loading channel 311, and repeat the above steps. The loading device 100 can continue the loading process, avoiding shutdown due to replenishing the material tray stack carrying circuit boards to the loading device 100, thereby improving the loading efficiency of the loading device 100. In actual implementation, an in-position sensor is provided on the loading platform 33 to determine whether there is a material tray above the loading platform 33, and then control the loading driving member 32 to rise or fall accordingly.

[0051] In actual implementation, the loading transmission member 341 is composed of two tracks, a motor, a transmission wheel and a transmission belt arranged opposite to each other. A motor is arranged on each track, and the transmission wheel is rotatably connected to the track. The transmission belt is sleeved on the output section of the motor and the transmission wheel. The material tray is placed on the transmission belt for transmission. The loading drive member 32 and the loading platform 33 are arranged between the two tracks. When the loading platform 33 needs to lift the material tray in the first transmission channel, the loading drive member 32 drives the loading platform 33 to descend below the transmission belt. When the stack of material trays reaches above the loading platform 33, the loading drive member 32 drives the loading platform 33 to rise to lift the stack of material trays from the transmission belt.

[0052] In one embodiment of the present invention, Figure 1and Figure 6 As shown, the unloading device 4 also includes an unloading transmission component 44 arranged on the machine 1, and the unloading transmission component 44 is provided with a second transmission channel, and the second transmission channel is connected to one end of the unloading channel 411, and the extension direction of the second transmission channel is arranged perpendicular to the extension direction of the unloading channel 411. The second transmission channel and the first transmission channel are arranged in parallel and at intervals below the table of the machine 1, and the second transmission channel is connected to one end of the unloading channel 411 away from the unloading position 412. During the unloading process of the tray, the unloading drive 42 drives the unloading table 43 carrying the tray stack to descend into the second transmission channel, and then the unloading transmission component 44 transfers the empty tray stack to the end of the second transmission channel away from the unloading channel 411, and the operator takes the tray stack out of the second transmission channel to complete the unloading of the tray. The end of the second transmission channel away from the unloading channel 411 can be directly connected to the conveying line of the tray to realize the automation of tray unloading.

[0053] Optionally, the unloading transmission assembly 44 includes a plurality of unloading transmission members 441, and the second transmission channel includes a plurality of unloading transmission segments 442, and each unloading transmission member 441 is provided with a unloading transmission segment 442. When the second transmission assembly transmits an unloaded material tray stack, each unloading transmission segment 442 can be placed with a material tray stack. The operator can unload materials together after placing multiple groups of material tray stacks in the second transmission channel to reduce the operator's operation frequency. It can be understood that the unloading transmission segment 442 close to the unloading channel 411 needs to remain in an unloaded state before the unloading driving member 42 drives the unloading platform 43 to descend to the second transmission channel to avoid the material tray stack blocking the movement of the unloading platform 43. In actual implementation, an in-position sensor is provided on the unloading platform 43, which is used to determine whether there is a material tray above the unloading platform 43. When the unloading driving component 42 drives the unloading platform 43 to move the material tray stack to the second transmission channel, the second transmission channel transmits the material tray stack to the end away from the unloading channel 411. After that, the in-position sensor detects that there is no material tray above the unloading platform 43, and the unloading driving component 42 can drive the unloading platform 43 to rise to the table top of the machine 1, waiting for the second transfer device 6 to place the material tray, and repeat the above steps to complete the unloading of the material tray.

[0054] In actual implementation, the structure of the unloading transmission member 441 can refer to the structural setting of the loading transmission member 341. The unloading transmission member 441 can also be composed of two relatively arranged tracks, a motor, a transmission wheel and a transmission belt. A motor is provided on each track, and the transmission wheel is rotatably connected to the track. The transmission belt is sleeved on the output section of the motor and the transmission wheel. The material tray is placed on the transmission belt for transmission, and the unloading drive member 42 and the unloading platform 43 are arranged between the two tracks.

[0055] In one embodiment of the present invention, Figure 1 and Figure 5As shown, the loading device 3 also includes a positioning drive member 35 and a positioning block 351. The positioning drive member 35 is connected to the machine 1 corresponding to the loading position 312, and the positioning block 351 is connected to the output end of the positioning drive member 35. The positioning drive member 35 is used to drive the positioning block 351 to abut or leave the material tray.

[0056] In this embodiment, after the loading drive 32 drives the loading platform 33 to drive the stack of trays carrying circuit boards to move along the loading channel 311 to the loading position 312, the first transfer device 5 can transfer the circuit boards carried by the topmost tray of the stack of trays. Before the first transfer device 5 transfers the circuit boards, the positioning drive 35 drives the positioning block 351 to approach and abut the tray from the side of the tray to position the tray that may be displaced during the transportation process of the loading channel 311, and at the same time avoid the tray from shaking when the first transfer device 5 transfers the circuit board, thereby improving the accuracy of the first transfer device 5 in positioning the circuit board. It can be understood that the positioning block 351 can cooperate with the positioning protrusion 331 on the loading platform 33 to abut the tray from different directions, thereby improving the positioning effect of the tray. The loading enclosure 31 is provided with an infrared sensor or a photoelectric sensor corresponding to the loading position 312, which is used to determine whether the loading platform 33 drives the tray to rise to the loading position 312. The material suction enclosure is also provided with an infrared sensor or a photoelectric sensor corresponding to the material unloading position 412 , which is used to determine whether the unloading platform 43 drives the empty material tray to descend to the material unloading position 412 .

[0057] In actual implementation, after the empty tray on the top of the tray stack is transferred to the unloading device 4 by the second transfer device 6, the positioning drive 35 drives the positioning block 351 to retract, and then the loading drive 32 drives the loading platform 33 to rise so that the next tray reaches the preset position, and the positioning drive 35 drives the positioning block 351 to reposition the tray, and the positioning of each tray is repeated.

[0059] In this embodiment, after the loading drive 32 drives the loading platform 33 to drive the tray stack to the loading position 312, the limit drive 361 drives the limit plate 362 to extend, so that the limit plate 362 suppresses the tray below the top tray of the tray stack, so as to prevent the first transfer device 5 from lifting the tray below when transferring the circuit board in the top tray or the second transfer device 6 from lifting the tray below when transferring the top tray, causing the circuit board in the tray below to be displaced or collided, so as to avoid affecting the positioning of the circuit board by the first transfer device 5 or causing damage to the circuit board.

The limit drive 361 can be a cylinder or an electric cylinder, etc., which is not specifically limited here. It can be understood that the limit assembly 36 can be configured to press the tray on the top layer of the tray stack to prevent the first transfer device 5 from lifting the tray on the top layer when transferring the circuit board in the tray, causing the tray to move.

[0061] In one embodiment of the present invention, Figure 1 , Figure 7 and Figure 8 As shown, the first transfer device 5 includes a first X-axis driving member 51, a first Y-axis driving member 52, a first Z-axis driving member 53, a rotating member 54 and a first adsorbing member 55, wherein the first X-axis driving member 51 is connected to the machine 1, the first Y-axis driving member 52 is connected to the output end of the first X-axis driving member 51, the first Z-axis driving member 53 is connected to the output end of the first Y-axis driving member 52, the rotating member 54 is connected to the output end of the first Z-axis driving member 53, and the first adsorbing member 55 is connected to the output end of the rotating member 54; wherein the driving direction of the first X-axis driving member 51 is , the driving direction of the first Y-axis driving member 52 and the driving direction of the first Z-axis driving member 53 are arranged perpendicularly in pairs; and / or, the second transfer device 6 includes a second Y-axis driving member 61, a second Z-axis driving member 62 and a second adsorption member 63, the second Y-axis driving member 61 is connected to the machine 1, the second Z-axis driving member 62 is connected to the output end of the second Y-axis driving member 61, and the second adsorption member 63 is connected to the output end of the second Z-axis driving member 62; wherein, the driving direction of the second Y-axis driving member 61 and the driving direction of the second Z-axis driving member 62 are arranged perpendicularly.

By controlling the first X-axis driving component 51, the first Y-axis driving component 52 and the first Z-axis driving component 53, the first adsorption component 55 can be driven to reach any position in the travel space, and the loading position 312 and the placement position 22 are located in the travel space, and then the first X-axis driving component 51, the first Y-axis driving component 52 and the first Z-axis driving component 53 can transfer the circuit board located at the loading position 312 to the carrier at the placement position 22. The loading position 312 and the unloading position 412 are extended along the Y-axis direction and are both on the running track of the second Y-axis driving member 61. The second Z-axis driving member 62 is used to drive the second adsorption member 63 along the Z-axis direction to approach or move away from the loading position 312 or the unloading position 412.

The setting of the rotating axis can change the orientation of the circuit board adsorbed by the first adsorption member 55 to meet the transportation requirements of the circuit board when the orientations of the circuit board placement slots in the material tray and the carrier are different.

[0064] In actual implementation, the first X-axis driving member 51, the first Y-axis driving member 52 and the first Z-axis driving member 53 can all be a combination of motors, screws and slide rails, or conventional linear driving mechanisms such as electric cylinders or pneumatic cylinders.

[0066] In this embodiment, two circuit boards can be placed on each tray and carrier at the same time. Correspondingly, two first adsorbing members 55 can be provided. The two first adsorbing members 55 are used to adsorb two circuit boards respectively, so that the first transfer device 5 can transfer two circuit boards at the same time. Before the first adsorbing member 55 adsorbs or places the circuit board, the circuit board or carrier can be positioned by the visual positioning component 56 so that the first adsorbing member 55 can accurately adsorb or place the circuit board.

[0067] In actual implementation, the visual positioning component 56 is composed of an illumination component 561 and a camera 562. The illumination component 561 is arranged along the axial direction of the camera 562, and the illumination component 561 can be an aperture. The loading device 100 also has a detection device 9, which includes a detection camera arranged on the machine 1. The machine 1 is provided with a defect position corresponding to the detection camera. After the first transfer device 5 takes the circuit board from the material tray at the loading position 312 and places the circuit board in front of the carrier at the placement position 22, the first transfer device 5 can transport the circuit board to the detection camera 562 for detection. If the circuit board has defects, the first transfer device 5 places the circuit board at the defect position. If the circuit board has no defects, the first transfer device 5 places the circuit board normally in the carrier.

[0069] In this embodiment, when the empty carrier in the transmission channel 21 is transferred to the placement position 22, the lifting drive 71 drives the lifting plate 72 to lift up, so as to lift the empty carrier from the transmission channel 21, and the second transfer device 6 picks up the circuit board from the loading position 312, and transfers the circuit board to the lifted carrier, and then the lifting drive 71 drives the lifting plate 72 to descend, so that the carrier loaded with the circuit board returns to the transmission channel 21, and the transmission device 2 transfers the carrier connected to the circuit board to the downstream equipment. The lifting drive 71 drives the lifting plate 72 to lift the carrier, which can provide support for the carrier, and prevent the carrier from being deformed when the second transfer device 6 places the circuit board on the carrier, so that the circuit board cannot be placed in place.

[0070] In actual implementation, the transmission device 2 includes tracks arranged relatively to each other, each track is provided with a motor, a driven wheel and a transmission belt, the transmission belt is sleeved on the output end of the motor and the driven wheel, the carrier is placed on the transmission belt, and the motor drives the transmission belt to rotate and then drives the carrier to move along the transmission channel 21, the lifting drive 71 and the lifting plate 72 are arranged between the two tracks, and the lifting plate 72 is lifted from the middle part of the bottom surface of the lifting plate 72. The lifting drive 71 is a cylinder or an electric cylinder, and the lifting plate 72 is provided with a guide shaft, and the machine 1 is provided with a bearing corresponding to the guide shaft, and the guide shaft is transmitted in the bearing, so that the lifting drive 71 drives the lifting plate 72 to rise or fall more stably. The lifting plate 72 is also provided with a positioning pin, and the carrier is provided with a positioning hole corresponding to the positioning pin. When the lifting assembly 7 lifts the carrier, the positioning pin is inserted into the positioning hole to realize the positioning and limiting of the carrier by the lifting plate 72. A limiting plate can be set on the top surface of the track, and the carrier is transported and moved between the limiting plate and the conveyor belt. When the lifting assembly 7 lifts the carrier, the top surface of the carrier abuts against the limiting plate to cooperate with the lifting plate 72 to limit the carrier, thereby preventing the carrier from shaking when the second transfer device 6 transfers the circuit board, affecting the accuracy of circuit board placement.

[0071] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the loading equipment 100 also includes two blocking components 8, which are arranged at both ends of the placement position 22 along the extension direction of the transmission channel 21. The blocking components 8 include a lifting drive member 81 and a blocking column 82, and the blocking column 82 is connected to the output end of the lifting drive member 81.

[0072] In this embodiment, the blocking components 8 are respectively arranged at both ends of the placement position 22, and one of the blocking components 8 is used to block the carrier that has arrived at the placement position 22, so that the carrier is temporarily located at the placement position 22, and prevents the carrier from continuing to move along the transmission channel 21, and then the lifting component 7 lifts the carrier located at the placement position 22 to wait for the placement of the circuit board. The other blocking component 8 is used to block the next carrier that is about to arrive at the placement position 22, and prevents the next carrier that is about to arrive at the placement position 22 from entering the placement position 22 along the transmission channel 21 when the lifting component 7 lifts the carrier located at the placement position 22, affecting the lifting component 7 to lift or lower the carrier located at the placement position 22 normally. The blocking component 8 is composed of a lifting drive 81 and a blocking column 82, and the lifting drive 81 drives the blocking column 82 to rise or fall to block or release the carrier.

[0073] In actual implementation, the transmission device 2 can remain in operation throughout the entire loading process. The setting of the blocking component 8 can prevent the transmission device 2 from stopping at the carrier plate 22 due to repeated starting and stopping, thereby increasing the service life of the transmission device 2.
