[0037] Please refer to Figures 1 to 8 As shown, the present invention proposes a loading device 100 for loading a circuit board in a first carrier tray to a second carrier tray, the loading device 100 comprises a machine 1, a first transmission device 2, a second transmission device 3, a transfer device 4 and a material unloading device 5, the first transmission device 2 is arranged on the machine 1, the first transmission device 2 is provided with a first transmission channel 211, the first transmission channel 211 is used to transmit the first carrier tray carrying the circuit board; the second transmission device 3 is arranged on the machine 1, the second transmission device 3 is provided with a second transmission channel, the second transmission channel is used to transmit the second carrier tray; the transfer device 4 comprises a transfer component 41 and a first adsorption component 42, the transfer component 41 is connected to the machine 1, the first adsorption component 42 is connected to the output end of the transfer component 41, the first adsorption component 42 is used to adsorb the circuit board; the material unloading device 5 comprises a material unloading drive component 51 and a material unloading fixing component 52, the material unloading drive component 51 is connected to the machine 1, the material unloading fixing component 52 is connected to the output end of the material unloading drive component 51, and the material unloading fixing component 52 is used to take the empty first carrier tray.
[0038] In this embodiment, the first transmission device 2 is provided with a first transmission channel 211, which is connected to the transmission outlet of the previous processing equipment and is used to receive the first carrier carrying the circuit board. The second transmission device 3 is provided with a second transmission channel, which is used to transmit the empty second carrier. When the first carrier carrying the circuit board reaches the specified position of the first transmission channel 211 and the empty second carrier reaches the specified position of the second transmission channel, the transfer component 41 drives the first adsorption component 42 to approach the first carrier carrying the circuit board, and the first adsorption component 42 adsorbs the circuit board. Then the transfer component 41 drives the first adsorption component 42 to move toward the second carrier, and the second adsorption component 521 places the circuit board on the second carrier. The second transmission channel can be connected to the transmission inlet of the next processing equipment, and directly transfer the second carrier carrying the circuit board to the next processing equipment. At the same time, the unloading drive component 51 drives the unloading fixed component 52 to approach the empty first carrier, and the unloading fixed component 52 takes the empty first carrier. Then the unloading drive component 51 drives the unloading fixed component 52 to drive the empty first carrier to leave the first transmission channel 211 and unload it. The first transmission channel 211 is connected to the upstream processing assembly line, and the second transmission channel is connected to the downstream processing assembly line. In this way, the automatic replacement of the circuit board carrier between the upstream processing assembly line and the downstream processing assembly line can be realized, so that the entire assembly line can be set up as an integrated unit, effectively improving the assembly line processing efficiency of the circuit board.
[0039] In actual implementation, the first carrier and the second carrier are respectively suitable carriers for the upstream device and the downstream device connected to the carrier changing device 100. The first carrier and the second carrier are both provided with placement slots for placing the circuit board.
[0040] In one embodiment of the present invention, Figures 1 to 3 As shown, the first transmission device 2 includes a transmission component 21, a first lifting drive member 22 and a first lifting platform 23 arranged on the machine 1. The transmission component 21 is provided with a first transmission channel 211 and a picking position 212 located at the first transmission channel 211. The first lifting drive member 22 is arranged on the machine 1 corresponding to the picking position 212. The first lifting platform 23 is connected to the output end of the first lifting drive member 22. The first lifting drive member 22 is used to drive the first lifting platform 23 to drive the first carrier on the first transmission channel 211 to approach or move away from the first transmission channel 211.
[0041] In this embodiment, the transmission component 21 is provided with a first transmission channel 211 and a pick-up position 212 located at the first transmission channel 211. When the transmission component 21 transports the first carrier carrying the circuit board to the pick-up position 212, the first lifting drive 22 drives the first lifting platform 23 to lift up to lift the first carrier from the first transmission channel 211. Then the transfer component 41 drives the first adsorption component 42 to adsorb the circuit board in the first carrier, so that it can be ensured that when the transfer device 4 adsorbs and transfers the circuit board, the position of the first carrier remains unchanged and does not move in the first transmission channel 211, so that the transfer device 4 can accurately pick up the circuit board in the first carrier located at the pick-up position 212. Then the unloading device 5 unloads the vacant first carrier. It can be understood that after the first carrier at the pick-up position 212 is unloaded, the first lifting drive 22 drives the first lifting platform 23 to descend to avoid interfering with the next first carrier entering the pick-up position 212.
[0042] In actual implementation, the transmission component 21 includes two tracks arranged at intervals, each track is provided with a motor, a driving wheel and a driven wheel, a conveyor belt is mounted on the driving wheel and the driven wheel, the motor drives the driving wheel to rotate to drive the conveyor belt to move, and the two ends of the bottom surface of the first carrier are respectively placed on the conveyor belts of the two tracks, the first lifting drive member 22 and the first lifting platform 23 are arranged between the two tracks corresponding to the picking position 212, and the first lifting platform 23 lifts the first carrier by lifting the middle part of the bottom surface of the first carrier.
[0043] It can be understood that the transmission component 21 is provided with an entrance connected to the first transmission channel 211, and the entrance is used to communicate with the transmission outlet in the processing equipment of the previous step. The end of the first transmission channel 211 away from the entrance is the end of the first transmission channel 211. The transmission component 21 is provided with a blocking buffer corresponding to the end of the first transmission channel 211. The picking position 212 is set at a position close to the end of the first transmission channel 211. The picking position 212 is provided with an infrared sensor. When the first transmission channel 211 moves the first carrier to the end of the first transmission channel 211, the first carrier abuts against the blocking buffer, and the infrared sensor is triggered. The first carrier arrives at the picking position 212, and the first lifting drive 22 drives the first lifting platform 23 to rise, lift the first carrier, and provide sufficient support for the first carrier when the transfer device 4 takes the circuit board to avoid affecting the taking of the circuit board. The first lifting platform 23 is provided with a first positioning pin that cooperates with the first carrier to position and fix the first carrier. In this embodiment, the first lifting drive member 22 includes a cylinder and a guide bearing, the first lifting platform 23 is connected to the output end of the cylinder, the guide bearing is connected to the machine 1, the first lifting platform 23 is provided with a guide rod corresponding to the guide bearing, the guide rod is inserted into the guide bearing, and the cylinder drives the first lifting platform 23 and the guide rod to rise and fall along the guide bearing. The first lifting drive member 22 can also be a combination of a motor, a screw and a guide rail, which is not specifically limited here.
[0044] In this embodiment, the first transmission device 2 also includes a limit assembly 24 located on both sides of the pick-up position 212. When the first lifting drive 22 drives the first lifting platform 23 to lift the first carrier to a certain height, the limit assemblies 24 located on both sides of the pick-up position 212 relatively press the two sides of the first carrier to clamp and fix the first carrier, so as to prevent the first carrier from being lifted up when the transfer device 4 adsorbs the circuit board in the first carrier, which is not conducive to the transfer of the circuit board or the subsequent unloading of the first carrier. At the same time, the limit assembly 24 relatively presses the first carrier and makes the first carrier in a central position, which is conducive to the transfer device 4 to position the circuit board on the first carrier. In actual implementation, the limit assembly 24 is composed of a limit cylinder 241 and a limit block 242. The limit cylinder 241 can be set on the transmission assembly 21, and the limit block 242 is connected to the output end of the limit cylinder 241. The limit cylinder 241 extends or retracts by driving the limit block 242 to press or release the first carrier.
[0045] In one embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the second transmission device 3 includes a loading transmission member 31, a unloading transmission member 32 and an intermediate transmission member 33, the second transmission channel includes a loading transmission channel 311, a unloading transmission channel 321 and an intermediate transmission channel 331, the loading transmission member 31, the unloading transmission member 32 and the intermediate transmission member 33 are respectively provided with a loading transmission channel 311, a unloading transmission channel 321 and an intermediate transmission channel 331, the loading transmission member 31 and the unloading transmission member 32 are spaced apart on the machine 1, the intermediate transmission member 33 is movably provided on the machine 1, the intermediate transmission member 33 is used to transfer the second carrier from the loading transmission channel 311 to the unloading transmission channel 321, the unloading transmission member 32 is also provided with a placement position 322 located in the unloading transmission channel 321, and the placement position 322 is used for the transfer device 4 to place the circuit board.
[0046] In this embodiment, the loading transmission member 31 is provided with a loading transmission channel 311, the loading transmission channel 311 is used to transmit the empty second carrier, the unloading transmission member 32 is used to transmit the second carrier loaded with circuit boards, and the intermediate transmission member 33 is movably arranged on the machine 1, and can move between the loading transmission member 31 and the unloading transmission member 32 to transfer the empty second carrier in the loading transmission channel 311 to the unloading transmission channel 321. The loading transmission member 31 and the unloading transmission member 32 are arranged at intervals on the machine 1 to divide the second transmission channel, thereby reducing the volume of the entire loading device 100. When the second carrier moves to the placement position 322 of the unloading transmission channel 321, the transfer device 4 places the adsorbed circuit board on the second carrier.
[0047] In actual implementation, the specific composition of the upper material transmission member 31, the lower material transmission member 32 and the intermediate transmission member 33 can be set with reference to the transmission assembly 21. The upper material transmission member 31, the lower material transmission member 32 and the intermediate transmission member 33 are all composed of two tracks arranged at intervals, each track is provided with a motor, a driving wheel and a driven wheel, and a conveyor belt is sleeved on the driving wheel and the driven wheel. The motor drives the driving wheel to rotate to drive the conveyor belt to move, and the second carrier is placed on the conveyor belt for transmission and movement.
[0048] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the second transmission device 3 also includes a second lifting drive member 34 and a second lifting platform 35. The second lifting drive member 34 is arranged on the machine 1 corresponding to the placement position 322. The second lifting platform 35 is connected to the output end of the second lifting drive member 34. The second lifting drive member 34 is used to drive the second lifting platform 35 to drive the second carrier located at the placement position 322 away from or close to the unloading transmission channel 321.
[0049] In this embodiment, the second lifting drive member 34 is provided on the machine 1 corresponding to the placement position 322, and the second lifting platform 35 is connected to the output end of the second lifting drive member 34. When the unloaded second carrier moves to the placement position 322 of the unloading transmission channel 321, the second lifting drive member 34 drives the second lifting platform 35 to rise to lift the second carrier, and then the transfer device 4 places the circuit board on the second carrier. The second lifting platform 35 is provided with a second positioning pin corresponding to the second carrier, and the second positioning pin can cooperate with the second carrier to prevent the second carrier from moving on the second lifting platform 35.
[0050] In actual implementation, the structures of the second lifting drive 34 and the second lifting platform 35 can be set with reference to the first lifting drive 22 and the first lifting platform 23. The second lifting drive 34 can be set between the two tracks in the unloading transmission member 32, and the second lifting platform 35 is connected to the output end of the second lifting drive 34 in a detachable manner. A baffle is also provided on the track of the second transmission device 3, and the second carrier moves between the baffle and the conveyor belt. The baffle can prevent the second lifting drive 34 and the second lifting platform 35 from lifting the second carrier too high, causing the position of the second carrier to shift, which is not conducive to the second lifting drive 34 and the second lifting platform 35 to put the second carrier back to the conveyor belt. When the second lifting drive 34 and the second lifting platform 35 lift the second carrier, the top surface of the second carrier abuts against the baffle to cooperate with the second lifting platform 35 to limit the carrier, so as to prevent the second carrier from shaking when the circuit board is placed, affecting the accuracy of the circuit board placement.
[0051] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4As shown, the loading transmission member 31 and the unloading transmission member 32 are spaced apart in a direction perpendicular to the machine 1, and the second transmission device 3 also includes a lifting drive assembly 36, the lifting drive assembly 36 is connected to the machine 1, and the intermediate transmission member 33 is connected to the output end of the lifting drive assembly 36, and the lifting drive assembly 36 is used to drive the intermediate transmission member 33 to move between the loading transmission member 31 and the unloading transmission member 32.
[0052] In this embodiment, the upper material transmission member 31 and the lower material transmission member 32 are arranged on the machine 1 with an upper and lower interval, so as to reduce the length of the space occupied by the second transmission channel, thereby reducing the volume of the load-changing device 100. The outlet of the upper material transmission channel 311 and the inlet of the lower material transmission channel 321 formed by the upper material transmission member 31 and the lower material transmission member 32 are located on the same plane perpendicular to the machine 1, the lifting drive assembly 36 is connected to the machine 1, and the intermediate transmission member 33 is connected to the output end of the lifting drive assembly 36, and the lifting drive assembly 36 drives the intermediate transmission member 33 to move between the outlet of the upper material transmission channel 311 and the inlet of the lower material transmission channel 321. When the lifting drive component 36 drives the intermediate transmission member 33 to approach the loading transmission member 31 so that the intermediate transmission channel 331 is aligned with the exit of the loading transmission channel 311, at this time, the transmission direction of the intermediate transmission channel 331 is consistent with the transmission direction of the loading transmission channel 311, and the second carrier in the loading transmission channel 311 is transmitted to the intermediate transmission channel 331. Then, the lifting drive component 36 drives the intermediate transmission member 33 to approach the unloading transmission channel 321 so that the intermediate transmission channel 331 is aligned with the entrance of the unloading transmission channel 321, and the second carrier in the intermediate transmission channel 331 is transmitted to the unloading transmission channel 321.
[0053] In actual implementation, the lifting drive component 36 includes a lifting rail, a slider, a lifting motor, a lifting screw and a mounting plate. The lifting rail and the lifting motor are connected to the machine platform 1. The mounting plate is slidably arranged on the lifting rail through the slider. The screw is connected to the output end of the lifting motor and is threadedly connected to the mounting plate. The lifting motor drives the mounting plate to move along the lifting rail by driving the screw to rotate. The intermediate transmission member 33 is arranged on the mounting plate, so that the lifting drive component 36 drives the intermediate transmission member 33 to rise and fall.
[0054] In one embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the second transmission device 3 also includes a first blocking component 37, a second blocking component 38 and a third blocking component 39. The first blocking component 37 is arranged at one end of the loading transmission channel 311 close to the intermediate transmission component 33, the second blocking component 38 is arranged at the corresponding placement position 322 of the unloading transmission channel 321, and the third blocking component 39 is arranged at one end of the intermediate transmission channel 331 close to the unloading transmission component 32.
[0055] In this embodiment, the first blocking component 37 is disposed at one end of the loading transmission channel 311 close to the intermediate transmission member 33. When the loading transmission channel 311 is not aligned with the intermediate transmission channel 331, the first blocking component 37 blocks the second carrier on the loading transmission channel 311 to prevent the second carrier from slipping out of the loading transmission channel 311. When the loading transmission channel 311 is aligned with the intermediate transmission channel 331, the first blocking component 37 no longer blocks the second carrier on the loading transmission channel 311, and the second carrier on the loading transmission channel 311 can be transferred to the intermediate transmission channel 331. Similarly, when the second carrier reaches the placement position 322 of the unloading transmission channel 321, the second blocking component 38 blocks the second carrier at the placement position 322 from continuing to move along the unloading transmission channel 321, waiting for the transfer device 4 to place the circuit board on the second carrier. After the circuit board is placed on the second carrier, the second blocking component 38 no longer blocks the second carrier, and the second carrier carrying the circuit board continues to move along the unloading transmission channel 321. During the process of the intermediate transmission member 33 carrying the second carrier plate moving from the upper transmission member 31 to the lower transmission member 32, the transmission direction of the intermediate transmission channel 331 is consistent with the transmission direction of the lower transmission channel 321, and the third blocking component 39 blocks the second carrier plate in the intermediate transmission channel 331 to prevent the second carrier plate from slipping out of the intermediate transmission channel 331. When the intermediate transmission channel 331 is aligned with the lower transmission channel 321, the third blocking component 39 no longer blocks the second carrier plate, so that the second carrier plate can be transferred from the intermediate transmission channel 331 to the lower transmission channel 321. Under the action of the first blocking component 37, the second blocking component 38 and the third blocking component 39, the loading transmission component 31, the intermediate transmission component 33 and the unloading transmission component 32 can all maintain an operating state during the transmission process of the second carrier. The loading transmission component 31, the intermediate transmission component 33 and the unloading transmission component 32 do not need to fix the position of the second carrier by starting and stopping, thereby avoiding the circuit board in the second carrier from being dislocated, improving the positioning effect and efficiency of the second carrier, and at the same time extending the service life of the loading transmission component 31, the intermediate transmission component 33 and the unloading transmission component 32.
[0056] In actual implementation, the first blocking component 37, the second blocking component 38 and the third blocking component 39 are all composed of a blocking cylinder and a blocking column. The blocking column is connected to the output end of the blocking cylinder. The blocking cylinder is connected to the loading transmission channel 311, the intermediate transmission channel 331 and the unloading transmission channel 321. The blocking cylinder drives the blocking column to rise or fall to block the second carrier or release the second carrier.

[0058] In this embodiment, the movable frame 561 is provided with rollers, and the worker can directly push the movable frame 561 to transfer the first carrier. After the unloading drive assembly 51 drives the unloading fixed assembly 52 to pick up the empty first carrier from the first transmission channel 211, the translation drive member 53 drives the push assembly 54 to reach the unloading position 11, the unloading drive assembly 51 drives the unloading fixed assembly 52 to place the first carrier on the push assembly 54, and then the translation drive member 53 drives the push assembly 54 to align with the placement rack 562 of a unloading vehicle 56, and the push assembly 54 pushes the first carrier to the placement rack 562 of the unloading vehicle 56. The unloading vehicle 56 includes at least two. When the placement rack 562 of one of the unloading vehicles 56 is full, after the push assembly 54 is loaded with the first carrier, the translation drive member 53 drives the push assembly 54 to align with the placement rack 562 of another unloading vehicle 56, and the push assembly 54 pushes the first carrier to the placement rack 562 of the unloading vehicle 56. In this way, when one of the unloading carts 56 is full, when the unloading cart 56 is manually moved away to unload the first loading tray thereon, the unloading device 5 can still unload the first loading tray normally, thereby ensuring the working efficiency of the loading device 100.
[0059] In actual implementation, the movable frame 561 is provided with a positioning groove, and the machine 1 is provided with a positioning cylinder and a positioning block connected to the output end of the positioning cylinder corresponding to the positioning groove. When the unloading trolley 56 is in place, the positioning cylinder drives the positioning block to extend into the positioning groove to fix the position of the unloading trolley 56, so as to prevent the unloading trolley 56 from moving when the unloading device 5 unloads materials, resulting in the first carrier being unable to smoothly enter the placement frame 562. It can be understood that the movable frame 561 is provided with a placement table corresponding to the placement frame 562, and the placement table is provided with a through hole, and the placement frame 562 can be placed on the placement table and slidably connected with the movable frame 561. The placement rack 562 is provided with a plurality of stacked placement positions 322, each placement position 322 can correspond to a first loading tray. When the lowering trolley 56 is fixed in place, the output end of the third lifting drive member 55 is opposite to the through hole of the placement table, and the third lifting drive member 55 drives the placement rack 562 to rise until the placement position 322 of the lowest layer of the placement rack 562 is aligned with the pushing assembly 54, and the pushing assembly 54 pushes a first loading tray into a placement position 322. Then the third lifting drive member 55 drives the placement rack 562 to descend a distance of a placement position 322, so that the pushing assembly 54 can push the next first loading tray into another placement position 322, until the placement position 322 of the placement rack 562 is full of the first loading tray. At this time, the third lifting drive member 55 drives the placement rack 562 to descend, so that the placement rack 562 is placed on the placement table of the movable frame 561, and the worker can control the positioning cylinder to drive the positioning block to retract, and transfer the first loading tray by pushing the lowering trolley 56. In actual implementation, the third lifting drive member 55 can be a combination of a motor, a lead screw and a slide rail or an electric slide rail, etc. The output end of the third lifting drive member 55 is provided with a plate body that can pass through the through hole of the placement table.

The translation plate is slidably connected to the translation track through a slider, the translation motor and the translation driven wheel are respectively arranged at both ends of the translation track, the translation drive belt is sleeved on the output end of the translation motor and the translation driven wheel, the translation plate is connected to the translation drive belt, the translation motor drives the translation drive belt to rotate to drive the translation plate to move along the translation track, and the pusher assembly 54 is arranged on the translation plate, so that the translation drive member 53 can drive the pusher assembly 54 to move between the material discharge position 11 and the unloading vehicle 56. Transmission by the translation drive belt can reduce the space occupied by the translation drive member 53, which is convenient for the spatial layout of the load-changing device 100.
[0061] The push assembly 54 includes a push track, a push motor, a push block, a push belt and a push driven wheel.

At the discharge position 11, the first carrier is placed in the push track. When the translation drive 53 drives the push assembly 54 to align with the placement rack 562, the push motor drives the push belt to rotate so that the push block pushes the first carrier located in the push track into the placement rack 562. It can be understood that the driving direction of the translation drive 53 is set at an angle to the driving direction of the push assembly 54 to make full use of the space of the machine 1 and facilitate the setting of at least two unloading carts 56.

Driven by the first X-axis driving member 411, the first Y-axis driving member 412 and the first Z-axis driving member 413, the first adsorption member 42 and the visual positioning device can move between the picking position 212 of the first transmission channel 211 and the placement position 322 of the second transmission channel to transfer the circuit board in the first carrier at the picking position 212 to the second carrier at the placement position 322. Before the first adsorption member 42 adsorbs or releases the circuit board, the visual positioning member 43 needs to position the circuit board in the first carrier or the placement slot in the second carrier for placing the circuit board to ensure that the first adsorption member 42 can accurately adsorb the circuit board from the first carrier, or accurately place the circuit board in the placement slot in the second carrier. In actual implementation, the first adsorbent 42 and the visual positioning member 43 are arranged side by side at the output end of the first Z-axis driving member 413, and the transport component 41 first drives the visual positioning member 43 to position the circuit board or the second carrier, and then drives the first adsorbent 42 to adsorb or release the circuit board.

The second X-axis drive component 511 is connected to the machine 1, and the second Z-axis drive component 512 is connected to the output end of the second X-axis drive component 511. The unloading fixing component 52 is connected to the output end of the second Z-axis drive component 512. The driving direction of the second X-axis drive component 511 and the driving direction of the second Z-axis drive component 512 are vertically arranged.
[0066] In this embodiment, the second X-axis driving component 511 drives the second Z-axis driving component 512 to drive the unloading fixing component 52 to move between the first transmission channel 211 and the discharge position 11. The second Z-axis driving component 512 drives the unloading fixing component 52 to approach or move away from the first carrier plate on the first transmission channel 211, or drives the unloading fixing component 52 to approach or move away from the pushing component 54 located at the discharge position 11, so that the unloading fixing component 52 can pick up the first carrier plate at the first transmission channel 211, or place the picked up first carrier plate on the pushing component 54.
[0067] In actual implementation, the driving direction of the translation driver 53 is arranged parallel to the transmission direction of the first transmission channel 211, and both are arranged along the Y-axis direction. The connecting line between the pick-up position 212 of the first transmission channel 211 and the material placement position 11 of the machine 1 is parallel to the X-axis direction, and both are on the driving path of the second X-axis driver 511. The driving directions of the second X-axis driver 511 and the second Z-axis driver 512 are the X-axis direction and the Z-axis direction respectively. The second X-axis driver 511 and the second Z-axis driver 512 can be a combination of a motor, a screw and a slide rail, or a linear drive device such as a cylinder or an electric cylinder. The loading transmission member 31 and the unloading transmission member 32 are arranged at intervals along the Z-axis direction, the first transmission device 2, the intermediate transmission member 33 and the unloading transmission member 32 are arranged in sequence along the Y-axis direction, the pushing assembly 54 pushes the material along the X-axis direction, and the driving direction of the lifting drive assembly 36 is the Z-axis direction.
[0068] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the material unloading fixing component 52 includes a second adsorption component 521 and a clamping component 522, the second adsorption component 521 and the clamping component 522 are connected to the output end of the material unloading driving component 51, the clamping component 522 is provided with a clamping space, the second adsorption component 521 is provided in the clamping space, the second adsorption component 521 is used to adsorb or release the first carrier, and the clamping component 522 is used to clamp or release the first carrier.
[0069] In this embodiment, the material unloading driving component 51 drives the second adsorbent 521 and the clamping component 522 to approach the first carrier plate at the picking position 212, the second adsorbent 521 vacuum adsorbs the first carrier plate, the first carrier plate enters the clamping space, the clamping component 522 clamps the first carrier plate, and then the material unloading driving component 51 drives the second adsorbent 521 and the clamping component 522 to drive the first carrier plate to leave the first transmission channel 211 and move to the specified position, the second adsorbent 521 and the clamping component 522 release the first carrier plate for unloading. Under the adsorption of the second adsorbent 521 and the clamping of the clamping component 522, the unloading fixing component 52 can take the first carrier plate more stably.
[0070] In actual implementation, the clamping member 522 includes a clamping drive member and two clamping arms arranged opposite to each other, the two clamping arms are connected to the output end of the clamping drive member, and a clamping space is formed between the two clamping arms. The clamping drive member clamps or releases the first carrier by driving the two clamping arms to move closer to or away from each other. The second adsorption member 521 is provided with four adsorption nozzles, and the four adsorption nozzles are respectively arranged corresponding to the four corners of the first material box, so that when the second adsorption member 521 vacuum adsorbs the first carrier, the first carrier is evenly stressed to prevent the first carrier from moving and affecting the clamping effect of the clamping member 522.
[0071] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the loading device 100 further includes a detection device 6, which includes a lighting component 61 and a detection head 62 arranged on the machine 1. The detection head 62 is used to detect the circuit board. The machine 1 is provided with a defect position 12, and the defect position 12 is used to place a defective circuit board.
[0072] In this embodiment, after the transfer device 4 takes the circuit board from the first carrier, the transfer device 4 transfers the circuit board to the detection device 6, and the detection head 62 detects whether the circuit board is defective. If the detection head 62 detects that the circuit board is not defective, the transfer device 4 puts the circuit board into the second carrier. If the detection head 62 detects that the circuit board is defective, the transfer device 4 places the defective circuit board in the defect position 12 of the machine 1 for subsequent recycling. In this way, the circuit board is detected during the loading process to prevent the defective circuit board from flowing into the next processing equipment and wasting processing resources.
[0073] In actual implementation, two circuit boards are loaded on each first carrier, and correspondingly, the first adsorbents 42 in the transfer device 4 also include two, and the second carrier is also provided with two placement slots. At this time, the machine 1 is also provided with a good position 13, and the good position 13 and the defective position 12 are respectively arranged on both sides of the detection device 6. When the detection result of the detection device 6 on the two circuit boards carried by the transfer device 4 is that one circuit board is defect-free and the other circuit board is defective, the transfer device 4 places the defective circuit board in the defective position 12 and the non-defective circuit board in the good position 13, and the transfer device 4 takes two circuit boards from another first carrier again. When the current detection structure of the two circuits of another group is that one circuit board is defect-free and the other circuit board is defective, the transfer device 4 places the defective circuit board in the defective position 12, takes the non-defective circuit board previously placed in the good position 13, and places the two non-defective circuit boards in the second carrier. The good position 13 can be placed with a second carrier for temporarily placing circuit boards. It can be understood that a rotating driving member can be set at the output end of the first Z-axis driving member 413, and the first adsorption member 42 is connected to the output end of the rotating driving member so that the transfer device 4 also has rotational freedom of movement, and the rotating axis of the rotating driving member is set along the Z-axis direction to facilitate the detection device 6 to perform all-round detection of the circuit board.
