[0038] Please refer to Figures 1 to 8 As shown, the present invention proposes a loading device 100 for transferring circuit boards on a tray to a carrier, 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; the loading device 3 is arranged on the machine 1, and the loading device 3 is used to load stacked trays carrying circuit boards; the unloading device 4 is arranged on the machine 1, and the unloading device 4 is used to unload the stacked empty trays; the first transfer device 5 includes a first transfer component and a first adsorption component 55 provided 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 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, the two ends of which can be connected to the upstream equipment and 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. The loading device 3 loads the stacked trays containing circuit boards to the loading position 312. The first transfer component drives the first adsorption component 55 to approach the loading device 3. 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. The first adsorption component 55 places the circuit board into the tray located at the placement position 22. The transmission channel 21 transfers the tray containing the circuit board to the downstream equipment, which performs subsequent processing on the circuit board. The empty tray in the loading device 3 is transferred by the second transfer device 6 to the unloading device 4, which stacks and unloads it. It can be understood that the material tray is the carrier for the circuit board during transportation, and the carrier tray is the carrier for the circuit board on the production line. The loading equipment 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 slots for limiting the placement of the circuit board. The first adsorption member 55 uses a vacuum adsorption method to adsorb the circuit board.

[0041] In one embodiment of the present invention, Figure 2 、 Figures 4 to 6 As shown, the loading device 3 includes a loading enclosure 31, a loading drive 32 and a loading platform 33. The loading enclosure 31 is connected to the machine 1. The loading enclosure 31 encloses a loading channel 311. The loading channel 311 is provided with a loading position 312 corresponding to the first transfer device 5. The loading drive 32 is provided in the loading channel 311. The loading platform 33 is connected to the output end of the loading drive 32. The loading platform 33 is provided with a plurality of positioning protrusions 331 arranged at intervals. The loading drive 32 is used to drive the loading platform 33 to drive the material tray carrying the circuit board to the loading position. Position 312, the positioning protrusion 331 is used to position the material tray; and / or, the unloading device 4 includes a unloading enclosure 41, a unloading drive 42 and a unloading platform 43, the unloading enclosure 41 is connected to the machine 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 drive 42 is provided in the unloading channel 411, the unloading platform 43 is connected to the output end of the unloading drive 42, and the unloading drive 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 loading enclosure 31 encloses a loading channel 311, which is arranged perpendicular to the table top of the machine 1 and is connected to the table top of the machine 1. The loading drive 32 and the loading platform 33 are arranged in the loading channel 311, and the loading platform 33 is connected to the output end of the loading drive 32. During the loading process of the trays, the stacked trays loaded with circuit boards are placed on the loading platform 33. The loading drive 32 drives the loading platform 33 to move the tray stack along the loading channel 311 toward the machine 1. When the top tray of the tray stack reaches the loading position 312, the loading drive 32 stops running, and the first transfer device 5 transfers the circuit boards in the top tray. After the circuit boards in the top tray are transferred, the second transfer device 6 transfers the top 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, causing the tray stack to continue moving upward until the top tray loaded with circuit boards in the tray stack reaches the loading position 312. The first transfer device 5 then transfers the circuit boards, and the second transfer device 6 transfers the empty trays. This process is repeated until the tray stack is fully loaded. When a tray stack loaded with circuit boards is loaded, another tray stack loaded with circuit boards is manually replenished. This eliminates the need for frequent manual replenishment of trays loaded with circuit boards. The stacking of trays effectively improves replenishment efficiency, which indirectly improves circuit board loading efficiency.

[0043] In this embodiment, the unloading enclosure 41 encloses a unloading channel 411, which is vertically arranged to 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. The unloading drive 42 drives the unloading platform 43 to descend again until the uppermost tray on the unloading platform 43 reaches the unloading position 412, and the second transfer device 6 transfers the tray to the unloading platform 43, and repeats the above steps until all the 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 tray stacks loaded with circuit boards on the loading platform 33, the empty tray stacks on the unloading platform 43 are taken down, and the unloading platform 43 is emptied to prepare for placing the next group of tray stacks.

[0044] In actual implementation, the loading channel 311 and the unloading channel 411 are spaced apart; 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 to facilitate the smooth entry of the material tray into the unloading channel 411. The loading drive 32 and the unloading drive 42 are linear drive devices composed of electric cylinders and rails or motors, screws, and slide rails. The surface of the loading platform 33 is perpendicular to the driving direction of the loading drive 32, and the surface of the unloading platform 43 is perpendicular to the driving direction of the loading drive 32. No specific restrictions are made 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. The loading transmission component 34 is provided with a first transmission channel. The first transmission channel is connected to the end of the loading channel 311 away from the loading position 312. 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. 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. A worker can place 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 tray stack 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 pass through the loading channel 311 to reach the loading position 312, waiting for the first transfer device 5 and the second transfer device 6 to transfer the circuit boards and trays.

[0047] As will be appreciated, the loading device 3 and the unloading device 4 are located on the same side of the conveyor 2. The operating side of the loading device 100 is generally located on the side of the conveyor 2 facing away from the loading device 3 and the unloading device 4. Therefore, the provision of the first conveyor channel allows the operator to load trays containing circuit boards from the operating side of the loading device 100, thereby reducing the operator's workload. Furthermore, the end of the first conveyor channel, remote from the loading channel 311, can also be directly connected to the tray conveyor line to achieve automated tray loading.

[0048] In one embodiment of the present invention, Figure 4As shown, the loading transmission component 34 includes multiple loading transmission parts 341, and the first transmission channel includes multiple loading transmission sections 342. Each loading transmission part 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 conveyor channel is divided into multiple loading conveyor segments 342, each of which is formed by a loading conveyor element 341. When the first conveyor assembly is transporting a stack of trays, each loading conveyor segment 342 can accommodate a tray stack. This allows the operator to load multiple tray stacks onto the first conveyor channel at once, corresponding to the number of loading conveyor segments 342, thereby reducing operator operation frequency. In this embodiment, each loading conveyor element 341 operates independently to control the spacing between adjacent tray stacks in the loading conveyor channel 21 and ensure stable tray loading.

[0050] It can be understood that the loading transmission section 342 close to the loading channel 311 needs to remain in an unloaded state before the loading drive 32 drives the loading platform 33 to descend to the first transmission channel to avoid the material tray stack blocking the movement of the loading platform 33, so the loading transmission 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. The loading transmission member 341 stops operating. At this time, the loading platform 33 is located below the material tray stack, and the loading drive member 32 can drive the loading platform 33 to lift the material tray stack. After 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. The above steps are repeated, and the loading equipment 100 can continue the loading process, avoiding shutdown due to replenishing the material tray stack carrying circuit boards to the loading equipment 100, thereby improving the loading efficiency of the loading equipment 100. In actual implementation, a 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 drive member 32 to rise or fall accordingly.

[0051] In practice, the loading conveyor 341 consists of two opposing tracks, a motor, a transmission wheel, and a conveyor belt. Each track is equipped with a motor, and the transmission wheel is rotatably connected to the track. The conveyor belt is mounted on the output section of the motor and the transmission wheel. The trays are placed on the conveyor belt for transportation. The loading drive 32 and the loading platform 33 are located between the two tracks. When the loading platform 33 needs to lift a tray in the first transmission channel, the loading drive 32 drives the loading platform 33 to descend below the conveyor belt. When the stack of trays reaches above the loading platform 33, the loading drive 32 drives the loading platform 33 to rise, lifting the stack of trays from the conveyor belt.

[0052] In one embodiment of the present invention, Figure 1and Figure 6 As shown, the unloading device 4 also includes an unloading transmission assembly 44 disposed on the machine 1. The unloading transmission assembly 44 is provided with a second transmission channel, which is connected to one end of the unloading channel 411 and extends perpendicularly to the direction of extension of the unloading channel 411. The second transmission channel is arranged below the tabletop of the machine 1, parallel to and spaced apart from the first transmission channel. The second transmission channel is connected to the end of the unloading channel 411 away from the unloading position 412. During the unloading process, the unloading drive 42 drives the unloading platform 43 loaded with the stack of trays down into the second transmission channel. The unloading transmission assembly 44 then transfers the empty stack of trays to the end of the second transmission channel away from the unloading channel 411. The operator removes the stack of trays from the second transmission channel to complete the unloading of the trays. The end of the second transmission channel away from the unloading channel 411 can be directly connected to the tray conveyor line to achieve automated unloading of the trays.

[0053] Optionally, the unloading conveyor assembly 44 includes multiple unloading conveyors 441, and the second conveyor channel includes multiple unloading conveyor segments 442, with each unloading conveyor member 441 being provided with a single unloading conveyor segment 442. When the second conveyor assembly is transporting an empty stack of trays, each unloading conveyor segment 442 can accommodate a single tray stack. Operators can unload trays after multiple tray stacks have been placed in the second conveyor channel, reducing operator effort. It will be appreciated that the unloading conveyor segments 442 near the unloading channel 411 must remain unloaded before the unloading drive 42 drives the unloading platform 43 down the second conveyor channel to prevent the tray stack from obstructing 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 drive 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 drive 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. Each track is provided with a motor, 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 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 35 and a positioning block 351. The positioning drive 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 35. The positioning drive 35 is used to drive the positioning block 351 to abut against or leave the material tray.

[0056] In this embodiment, when the loading drive 32 drives the loading platform 33 to move the stack of trays carrying circuit boards along the loading channel 311 to the loading position 312, the first transfer device 5 can transfer the circuit boards carried by the trays on the top layer of the tray stack. 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, while preventing the tray from shaking when the first transfer device 5 transfers the circuit boards, thereby improving the accuracy of the first transfer device 5 in positioning the circuit boards. 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 has driven 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 unloading position 412 for determining whether the unloading platform 43 has driven the empty material tray to descend to the 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 driver 35 drives the positioning block 351 to retract. Then, the loading driver 32 drives the loading platform 33 to rise so that the next tray reaches the preset position. The positioning driver 35 drives the positioning block 351 to reposition the tray. This positioning process is repeated for each tray. The positioning driver 35 can be a pneumatic cylinder or an electric cylinder, etc., and is not specifically limited here.

[0058] In one embodiment of the present invention, Figure 1 and Figure 5 As shown, the loading device 3 also includes at least two limit assemblies 36, and the two limit assemblies 36 are relatively arranged on both sides of the loading position 312. The limit assemblies 36 include a limit driving member 361 and a limit plate 362. The limit driving member 361 is connected to the machine 1, and the limit plate 362 is connected to the output end of the limit driving member 361. The limit driving member 361 is used to drive the limit plate 362 to abut against or leave the material tray.

[0059] In this embodiment, after the loading drive 32 drives the loading platform 33 to bring the stack of trays 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 topmost tray in the stack. This prevents the first transfer device 5 from lifting the tray below when transferring the circuit board in the topmost tray, or the second transfer device 6 from lifting the tray below when transferring the topmost tray, causing the circuit boards in the lower tray to shift or collide, thereby preventing the first transfer device 5 from positioning the circuit boards or causing damage to the circuit boards. At least two limit members are included to suppress the tray from different sides, thereby improving the stability of the tray when being pressed.

[0060] In practice, the sidewalls of the trays are provided with gripping grooves. A limit driver 361 drives a limit plate 362 into or out of the grooves to suppress or release the trays. The limit driver 361 can be a pneumatic or electric cylinder, and is not specifically limited here. It will be appreciated that the limit assembly 36 can be configured to suppress the topmost tray in the stack to prevent the first transfer device 5 from lifting the topmost tray when transferring circuit boards therein, potentially causing the trays to shift.

[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 adsorption member 55. 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 adsorption 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.

[0062] In this embodiment, the driving direction of the first X-axis driving member 51, the first Y-axis driving direction and the first Z-axis driving member 53 are the X-axis direction, the Y-axis direction and the Z-axis direction, respectively, wherein the X-axis direction, the Y-axis direction and the Z-axis direction are three mutually perpendicular directions, and the X-axis, the Y-axis and the Z-axis can form a spatial rectangular coordinate system. By controlling the first X-axis driving member 51, the first Y-axis driving member 52 and the first Z-axis driving member 53, the first adsorption member 55 can be driven to any position within the travel space. The loading position 312 and the placement position 22 are located within the travel space, and then the first X-axis driving member 51, the first Y-axis driving member 52 and the first Z-axis driving member 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.

[0063] In one embodiment, the table top of the machine 1 is arranged parallel to the XY plane; the transmission channel 21 is extended along the Y-axis direction; the loading channel 311 and the unloading channel 411 are both extended along the Z-axis direction, and the loading channel 311 and the unloading channel 411 are spaced apart along the Y-direction; the first transmission channel and the second transmission channel are both extended along the X-direction, and the rotating axis of the rotating member 54 is arranged along the Z-axis direction. 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 component 51, the first Y-axis driving component 52 and the first Z-axis driving component 53 can all be a combination of a motor, a screw rod and a slide rail, or a conventional linear driving mechanism such as an electric cylinder or a pneumatic cylinder. The first adsorption component 55 and the second adsorption component 63 are vacuum adsorption components, which are not specifically limited here.

[0065] In one embodiment of the present invention, Figure 1 and Figure 7 As shown, the first adsorption parts 55 include two, and the first transfer device 5 also includes a visual positioning component 56. The two first adsorption parts 55 are arranged at intervals at the output end of the first Z-axis driving component 53. The visual positioning component 56 includes a lighting component 561 and a camera 562 arranged on the first Z-axis driving component 53.

[0066] In this embodiment, two circuit boards can be placed simultaneously on each tray and carrier. Accordingly, two first suction members 55 are provided, each used to suction two circuit boards, so that the first transfer device 5 can transfer two circuit boards simultaneously. Before the first suction members 55 suction or place the circuit boards, the visual positioning component 56 can be used to position the circuit boards or carrier to facilitate accurate suction or placement of the circuit boards by the first suction members 55.

[0067] In actual implementation, the visual positioning assembly 56 is composed of an illumination element 561 and a camera 562. The illumination element 561 is arranged along the axis of the camera 562, and the illumination element 561 can be an aperture. The loading device 100 also includes a detection device 9, which includes an inspection camera provided on the machine 1. The machine 1 is provided with a defect position corresponding to the inspection 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 inspection camera 562 for inspection. If the circuit board has defects, the first transfer device 5 places the circuit board in the defect position. If the circuit board does not have defects, the first transfer device 5 places the circuit board normally on the carrier.

[0068] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the loading equipment 100 also includes a jacking assembly 7 arranged at the placement position 22, the jacking assembly 7 includes a jacking drive 71 and a jacking plate 72, the jacking drive 71 is connected to the machine 1, the jacking plate 72 is connected to the output end of the jacking drive 71, and the jacking plate 72 is provided with a limiting protrusion 721.

[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 to lift the empty carrier from the transmission channel 21. The second transfer device 6 picks up the circuit board from the loading position 312 and transfers the circuit board to the lifted carrier. 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. 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, resulting in the circuit board being unable to be placed in place.

[0070] In actual implementation, the transmission device 2 includes relatively arranged tracks, 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, thereby driving 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. The machine 1 is provided with a bearing corresponding to the guide shaft. 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 component 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 the 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 component 8 includes 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, blocking assemblies 8 are respectively provided at both ends of the placement position 22. One blocking assembly 8 is used to block a carrier that has arrived at the placement position 22, so that the carrier is temporarily located at the placement position 22, preventing the carrier from continuing to move along the transmission channel 21. The lifting assembly 7 then lifts the carrier located at the placement position 22 to wait for the placement of the circuit board. The other blocking assembly 8 is used to block the next carrier that is about to arrive at the placement position 22, preventing 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 assembly 7 lifts the carrier located at the placement position 22, thereby affecting the normal lifting or lowering of the carrier located at the placement position 22 by the lifting assembly 7. The blocking assembly 8 is composed of a lifting drive 81 and a blocking column 82. 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 repeatedly starting and stopping so that the carrier plate stops at the placement position 22, thereby increasing the service life of the transmission device 2.
