[0034] As shown in Figure 1As shown in the figure, the automatic loader 10 for finished circuit boards of an embodiment includes a tray lifting device 100, trays 200, a board shifting device 300, an elastic support device 400, and a board feeding device 500. A plurality of trays 200 are stacked at the power output end of the tray lifting device 100 to form a tray group 200a. The tray lifting device 100 is used to lift the height of the tray group 200a. The board shifting device 300 is used to move the tray 200 at the top layer of the upper board tray group 200a so that the tray 200 at the top layer is spaced apart from the adjacent trays 200. The elastic support device 400, the power output end of the elastic support device 400 is used to extend between the tray 200 at the top layer and the adjacent trays 200. The board shifting device 300 is further used to place the tray 200 at the top layer on the power output end of the elastic support device 400, and the power output end of the elastic support device 400 is in elastic contact with the corresponding tray 200. The board feeding device 500 is arranged adjacent to the tray lifting device 100. The board feeding device 500 is used to convey the finished circuit boards. The board shifting device 300 is further used to move the finished circuit boards into the tray 200 at the top layer.

[0035] As Figure 1 shown in the figure, in this embodiment, when the automatic loader 10 for finished circuit boards works, the board shifting device 300 moves the tray 200 at the top layer to a predetermined height so that the tray 200 at the top layer is spaced apart from the adjacent trays 200, and the power output end of the elastic support device 400 is located between the tray 200 at the top layer and the adjacent trays 200. Then, the board shifting device 300 moves the finished circuit boards on the board feeding device 500 into the tray 200 at the top layer one by one. After the tray 200 at the top layer is filled with finished circuit boards, the tray 200 at the top layer is removed from the elastic support device 400. At this time, the tray 200 originally at the second layer becomes the tray 200 at the top layer. Then, the tray lifting device 100 drives the tray group 200a to rise by the height of one tray 200, and then the above actions are repeated. After all the trays 200 are removed, the power output end of the tray lifting device 100 drops to the lowest position, and then a plurality of empty trays 200 are stacked on the tray lifting device 100.

[0036] For the above-mentioned finished circuit board automatic loader 10, when the plate moving device 300 moves downward excessively, since the power output end of the elastic support device 400 is in elastic contact with the corresponding tray 200, the power output end of the elastic support device 400 can compress its volume, so that the top tray 200 moves downward by a certain distance, avoiding the violent collision between the finished circuit boards on the plate moving device 300 and the tray 200 or the finished circuit boards on the tray 200, thereby improving the qualified rate of the finished circuit boards. Moreover, since the top tray 200 and the adjacent tray 200, i.e., the second-layer tray 200, are arranged at intervals, contact between the top tray 200 and the second-layer tray 200 is avoided, thereby preventing the top tray 200 from colliding with the second-layer tray 200 when moving downward, and further preventing the problem of the tray group 200a being scattered when the plate moving device 300 places the plates, ensuring the subsequent normal operation of the finished circuit board automatic loader 10.

[0037] As Figure 1 shown, in one embodiment, the plate feeding device 500 is a belt conveyor, and multiple finished circuit boards are arranged in sequence along the conveying direction of the plate feeding device 500 to improve the feeding efficiency of the feeding device.

[0038] As Figure 2 shown, in one embodiment, the tray lifting device 100 includes a lifting drive mechanism 110 and a supporting bracket 120. The supporting bracket 120 is connected to the power output end of the lifting drive mechanism 110. The lifting drive mechanism 110 is used to drive the supporting bracket 120 to rise or fall, and multiple trays 200 are stacked on the supporting bracket 120. In this embodiment, the lifting drive mechanism 110 is a motor.

[0039] As Figure 3 shown, in one embodiment, the elastic support device 400 includes two support mechanisms 400a. The two support mechanisms 400a are respectively arranged on opposite sides of each tray 200. The power output end of each support mechanism 400a is used to extend between the top tray 200 and the adjacent tray 200. The plate moving device 300 is used to place the top tray 200 on the power output end of each support mechanism 400a, and the power output end of each support mechanism 400a is in elastic contact with the corresponding tray 200. In this embodiment, the power output ends of the two support mechanisms 400a are respectively in contact with two edges of the top tray 200, that is, the power output ends of the two support mechanisms 400a are respectively elastically supported on two edges of the top tray 200, improving the position stability of the top tray 200.

[0040] As Figure 3 and Figure 4As shown, in one embodiment, each support mechanism 400a includes a mounting frame 410, a telescopic driving member 420, a limiting steel plate 430, and an elastic contact member 440. The telescopic driving member 420 of each support mechanism 400a is mounted on the corresponding mounting frame 410. The limiting steel plate 430 of each support mechanism 400a is connected to the power output end of the corresponding telescopic driving member 420. The elastic contact member 440 of each support mechanism 400a is connected to the corresponding limiting steel plate 430. The telescopic driving member 420 of each support mechanism 400a is used to drive the corresponding limiting steel plate 430 and the corresponding elastic contact member 440 to extend into the space between the top tray 200 and the adjacent tray 200. The plate moving device 300 is used to move the finished circuit board of the board feeding device 500 onto the elastic contact member 440 of each support mechanism 400a, and the elastic contact member 440 of each support mechanism 400a is in elastic contact with the corresponding tray 200. In this embodiment, since the elastic contact member 440 of each support mechanism 400a is connected to the power output end of the corresponding telescopic driving member 420 through the limiting steel plate 430, the limiting steel plate 430 of each support mechanism 400a restricts the corresponding elastic contact member 440, preventing the elastic contact member 440 from deviating from the predetermined position, and thus ensuring that the elastic contact member 440 can still support the top tray 200 after being compressed.

[0041] As Figure 3 shown, further, the telescopic driving member 420 of each support mechanism 400a is a telescopic cylinder. Further, the elastic contact member 440 of each support mechanism 400a is a silicone structure. Of course, in other embodiments, the elastic contact member 440 of each support mechanism 400a can also be a rubber structure or other existing elastic structures.

[0042] As Figure 5 shown, in one embodiment, the plate moving device 300 includes a horizontal driving mechanism 310, a vertical driving mechanism 320, and an adsorption mechanism 330. The vertical driving mechanism 320 is mounted on the power output end of the horizontal driving mechanism 310. The adsorption mechanism 330 is mounted on the power output end of the vertical driving mechanism 320. The adsorption mechanism 330 is used to move the top tray 200 and the finished circuit board. In this embodiment, the adsorption mechanism 330 is jointly driven by the horizontal driving mechanism 310 and the vertical driving mechanism 320, enabling the adsorption mechanism 330 to move horizontally and vertically, improving the picking and placing accuracy of the adsorption mechanism 330.

[0043] As Figure 5As shown, in one embodiment, the horizontal driving mechanism 310 includes a lateral driving mechanism 311 and a longitudinal driving mechanism 312. The longitudinal driving mechanism 312 is installed at the power output end of the lateral driving mechanism 311, and the vertical driving mechanism 320 is installed at the power output end of the longitudinal driving mechanism 312. In this embodiment, the horizontal driving mechanism 310 includes the lateral driving mechanism 311 and the longitudinal driving mechanism 312. The lateral driving mechanism 311, the longitudinal driving mechanism 312, the vertical driving mechanism 320, and the adsorption mechanism 330 are connected in sequence, enabling the adsorption mechanism 330 to move horizontally and longitudinally, increasing the moving range of the adsorption mechanism 330, and further improving the picking and placing accuracy of the adsorption mechanism 330. Further, the lateral driving mechanism 311, the longitudinal driving mechanism 312, and the vertical driving mechanism 320 are all linear modules.

[0044] As Figure 5 shown, in one embodiment, the plate moving device 300 further includes a rotating mechanism 340. The rotating mechanism 340 is installed at the power output end of the vertical driving mechanism 320, and the adsorption mechanism 330 is installed at the power output end of the rotating mechanism 340, so that the adsorption mechanism 330 is installed at the power output end of the vertical driving mechanism 320 through the rotating mechanism 340. In this embodiment, the adsorption mechanism 330 is connected to the power output end of the rotating mechanism 340, enabling the rotating mechanism 340 to drive the adsorption mechanism 330 to rotate, allowing the adsorption mechanism 330 to rotate to a suitable angle for picking and placing materials, and enabling the adsorption mechanism 330 to adsorb circuit board products with different placement angles. Further, the rotating mechanism 340 is a motor.

[0045] As Figure 5 shown, in one embodiment, the adsorption mechanism 330 includes a connecting plate 331 and a plurality of suction nozzles 332. The connecting plate 331 is connected to the power output end of the rotating mechanism 340, and the plurality of suction nozzles 332 are spaced apart on the side of the connecting plate 331 facing away from the rotating mechanism 340. In this embodiment, the connecting plate 331 is connected to the rotating mechanism 340, and the plurality of suction nozzles 332 are spaced and connected to the connecting plate 331, enabling multiple position points of the circuit board product to be adsorbed by the adsorption mechanism 330, increasing the adsorption force of the adsorption mechanism 330, and further avoiding the problem of material dropping during picking and placing by the adsorption mechanism 330.

[0046] As Figure 5 shown, in one embodiment, the adsorption mechanism 330 further includes a plurality of connecting rods 333 spaced apart. Both ends of each connecting rod 333 are respectively connected to the power output end of the rotating mechanism 340 and the connecting plate 331, so that the connecting plate 331 is connected to the power output end of the rotating mechanism 340 through the plurality of connecting rods 333, extending the distance between each suction nozzle 332 and the rotating mechanism 340, enabling a greater downward movement distance of each suction nozzle 332, and increasing the adsorption range of each suction nozzle 332.

[0047] It can be understood that when the amount of excessive downward movement of the plate shifting device 300 is large, the power output end of the elastic support device 400 can be compressed to relieve the severe collision suffered by the finished circuit board. However, at this time, the buffering effect of the elastic support device 400 is still insufficient to avoid damage to the finished circuit board. Therefore, as Figure 6 and Figure 7 shown, in one embodiment, each tray 200 includes a frame 210, a bottom plate 220, and an elastic connection assembly 230. The frame 210 of each tray 200 is provided with an accommodation through hole 211. The bottom plate 220 of each tray 200 is located in the accommodation through hole 211 and is elastically connected to the corresponding frame 210 through the corresponding elastic connection assembly 230. In this embodiment, the elastic connection assembly 230 of each tray 200 and the corresponding bottom plate 220 are both located in the accommodation through hole 211 of the corresponding frame 210. The elastic connection assembly 230 of each tray 200 is respectively connected to the corresponding frame 210 and the corresponding bottom plate 220, so that the bottom plate 220 of each tray 200 is elastically connected to the corresponding frame 210 through the corresponding elastic connection assembly 230. When the amount of excessive downward movement of the plate shifting device 300 is large, the bottom plate 220 of the top tray 200 will be subjected to a driving force, causing the elastic connection assembly 230 of the top tray 200 to elastically deform along the downward movement direction of the plate shifting device 300, relieving the impact on the finished circuit board, that is, relieving the impact of the finished circuit board on the top tray 200 or the finished circuit board on the top tray 200, suppressing the problem of damage to the finished circuit board due to collision, and improving the qualification rate of the finished circuit board.

[0048] As Figure 6 and Figure 7As shown, further, the number of the elastic connection components 230 of each tray 200 is multiple. The multiple elastic connection components 230 of each tray 200 are evenly spaced along the circumferential direction of the corresponding bottom plate 220. A plurality of clamping grooves 212 are formed in the inner wall of the accommodation through hole 211 of each tray 200. The plurality of clamping grooves 212 of each tray 200 are arranged in one-to-one correspondence with the corresponding plurality of elastic connection components 230. A plurality of mounting grooves 221 are formed in the outer side surface of the bottom plate 220 of each tray 200. The plurality of mounting grooves 221 of the bottom plate 220 of each tray 200 are arranged in one-to-one correspondence with the corresponding plurality of elastic connection components 230. Each elastic connection component 230 includes a spring 231 and a clamping block 232. The spring 231 of each elastic connection component 230 is located in the corresponding mounting groove 221 and is connected to the corresponding bottom plate 220. The clamping block 232 of each elastic connection component 230 is located in the corresponding mounting groove 221 and is fixedly connected to the corresponding spring 231. The clamping block 232 of each elastic connection component 230 is further located in the corresponding clamping groove 212 and is clamped with the corresponding frame 210, so that the bottom plate 220 of each tray 200 is clamped with the corresponding frame 210 through the corresponding plurality of elastic connection components 230. In this embodiment, when the amount of excessive downward movement of the plate moving device 300 is relatively large, the bottom plate 220 of the top tray 200 will be subjected to a driving force, so that the springs 231 of the top tray 200 are stretched and elastically deformed along the downward movement direction of the plate moving device 300, alleviating the impact on the finished circuit board, that is, alleviating the impact of the finished circuit board on the tray 200 or the finished circuit board on the tray 200, suppressing the problem that the finished circuit board is damaged due to collision, and improving the qualification rate of the finished circuit board.

[0049] It can be understood that multiple finished circuit boards are placed on each tray 200, that is, multiple finished circuit boards are placed in the accommodation space jointly formed by the frame 210 and the corresponding bottom plate 220 of each tray 200. When it is necessary to install or use the finished circuit board on each tray 200, since the gap between the finished circuit board and the corresponding frame 210 is small, it is necessary to use a clamping jaw to clamp the edge of the finished circuit board and then take out the finished circuit board from the corresponding tray 200. However, since the clamping jaw is likely to scratch the edge of the finished circuit board when clamping the finished circuit board, the quality of the finished circuit board is reduced, and even the qualification rate of the finished circuit board is reduced.

[0050] Therefore, as Figure 7As shown, in one of the embodiments, the clamping block 232 of the elastic connection component 230 of each tray 200 is provided with a first disassembly inclined surface 2321. The first disassembly inclined surface 2321 of the clamping block 232 of the elastic connection component 230 of each tray 200 is arranged towards the upper side of the corresponding frame 210. The clamping groove 212 of the frame 210 of each tray 200 is provided with a second disassembly inclined surface 2121. The second disassembly inclined surface 2121 of the clamping groove 212 of the frame 210 of each tray 200 is arranged opposite to the corresponding first disassembly inclined surface 2321. In this embodiment, when removing the finished circuit board, the corresponding bottom plate 220 is pushed upward so that the first disassembly inclined surface 2321 of the corresponding clamping block 232 contacts the second disassembly inclined surface 2121 of the corresponding frame 210, and then the corresponding clamping block 232 moves upward along the corresponding second disassembly inclined surface 2121, and the corresponding clamping block 232 retracts into the installation groove 221 of the corresponding bottom plate 220 to prevent the corresponding clamping block 232 from hindering the upward separation of the corresponding bottom plate 220 from the corresponding frame 210, and then the finished circuit board is removed from the corresponding tray 200. This avoids using a clamping jaw to remove the finished circuit board, and further avoids the problem of the clamping jaw scratching the edge of the finished circuit board, thus improving the qualified rate of the finished circuit board.

[0051] However, due to the small gap between the finished circuit board and the frame 210, when the bottom plate 220 moves upward and deviates, the qualified rate of the finished circuit board will rub against the corresponding frame 210, thereby reducing the qualified rate of the finished circuit board. As Figure 7As shown, in one embodiment, an anti-scratch groove 213 is also formed on the inner wall of the accommodating through hole 211 of the frame 210 of each tray 200, and the anti-scratch groove 213 of the frame 210 of each tray 200 is adjacent to the corresponding snap-in groove 212, and the anti-scratch groove 213 of the frame 210 of each tray 200 is located on the upper side of the corresponding snap-in groove 212, and the anti-scratch groove 213 of the frame 210 of each tray 200 is arranged around the bottom plate 220, and each tray 200 also includes a soft anti-scratch ring 240, and the soft anti-scratch ring 240 of each tray 200 is a soft structure, and the soft anti-scratch ring 240 of each tray 200 is located in the corresponding anti-scratch groove 213 and connected to the corresponding frame 210, so that the soft anti-scratch ring 240 of each tray 200 is arranged around the corresponding bottom plate 220, and the soft anti-scratch ring 240 of each tray 200 is arranged around each circuit board finished product on the corresponding tray 200. In this embodiment, when the bottom plate 220 moves upward and deviates, the edge of the finished circuit board is scratched against the soft anti-scratch ring 240. Since the soft anti-scratch ring 240 is a flexible structure, the problem of the edge of the finished circuit board being scratched is avoided, and the qualified rate of the finished circuit board is improved. In addition, since the soft anti-scratch ring 240 of each tray 200 is arranged around the corresponding finished circuit board, the soft anti-scratch ring 240 of each tray 200 can also limit the position of the corresponding finished circuit board, avoiding the situation where the finished circuit board is separated from the corresponding tray 200 during transportation, thereby avoiding the problem of the finished circuit board being damaged during transportation, and further improving the qualified rate of the finished circuit board.

[0052] It can be understood that when the bottom plate 220 of each tray 200 is separated from the corresponding frame 210 upward, the clamping block 232 of each tray 200 abuts against the corresponding soft anti-scratch ring 240 under the action of the corresponding spring 231. However, since the soft anti-scratch ring 240 of each tray 200 is a soft structure, the clamping block 232 of each tray 200 is easier to embed into the corresponding soft anti-scratch ring 240 under the action of the corresponding spring 231, so that the clamping block 232 of each tray 200 is easier to get stuck in the corresponding soft anti-scratch ring 240, thereby making it easier for the bottom plate 220 of each tray 200 and the corresponding circuit board product to be unable to continue to move upward and separate from the corresponding frame 210, thereby making it easier for the corresponding circuit board product to be unable to be taken out smoothly. As Figure 7As shown, in one embodiment, the soft anti-scratch ring 240 of each tray 200 is a plastic airbag filled with gas. In this embodiment, when the clamping block 232 of each tray 200 is stuck in the corresponding soft anti-scratch ring 240, the corresponding bottom plate 220 is continuously moved upward, and the corresponding clamping block 232 will scratch the corresponding soft anti-scratch ring 240, so that the corresponding soft anti-scratch ring 240 is broken and deflated, thereby preventing the corresponding soft anti-scratch ring 240 from hindering the corresponding bottom plate 220 and the corresponding circuit board product from continuing to separate upward from the corresponding frame 210, thereby improving the efficiency of removing the circuit board product.

[0053] In order to prevent the bottom plate 220 of each tray 200 from being separated downward from the corresponding frame 210, thereby causing the corresponding circuit board product to be broken, thereby reducing the qualified rate of the circuit board product. Figure 7 As shown, in one embodiment, the bottom surface of the clamping block 232 of each tray 200 is a horizontal surface, the bottom wall of the clamping slot 212 of the frame 210 of each tray 200 is a horizontal surface, and the bottom wall of the clamping slot 212 of the frame 210 of each tray 200 is arranged opposite to the bottom surface of the corresponding clamping block 232 to prevent the clamping block 232 of each tray 200 from being separated from the corresponding clamping slot 212.

[0054] However, when the bottom plate 220 of each tray 200 weighs a large amount, the bottom plate 220 of each tray 200 will be more easily separated from the corresponding clamping groove 212. Therefore, if Figure 7 As shown, in one embodiment, the bottom surface of the clamping block 232 of each tray 200 is convexly provided with a plurality of embedded blocks 232a, and the bottom wall of the clamping groove 212 of the frame 210 of each tray 200 is provided with a plurality of embedded grooves 214. The plurality of embedded blocks 232a of the clamping block 232 of each tray 200 are correspondingly embedded in the plurality of embedded grooves 214 of the corresponding frame 210 one by one, so as to improve the connection strength between the clamping block 232 of each tray 200 and the corresponding frame 210, and improve the weighing capacity of the bottom plate 220 of each tray 200, so that each tray 200 can accommodate more finished circuit boards, so as to improve the handling efficiency of the finished circuit boards.

[0055] In one embodiment, the frame 210 of each tray 200 is further provided with a plurality of anti-drop slots 215, and the plurality of anti-drop slots 215 of each tray 200 are arranged one by one with the corresponding plurality of elastic connection components 230. When each clamping block 232 of each elastic connection component 230 is disengaged downward from the corresponding clamping slot 212, each clamping block 232 of each elastic connection component 230 is clamped in the corresponding anti-drop slot 215 under the push of the corresponding spring 231 to prevent the corresponding bottom plate 220 from falling, thereby avoiding the problem of the finished circuit board being damaged due to falling, and improving the qualified rate of the finished circuit board.

[0056] ​The present application also provides a circuit board production device, including the automatic loader 10 for circuit board finished products according to any one of the above embodiments.

[0057] Compared with the prior art, the present invention has at least the following advantages:

[0058] For the above-mentioned automatic loader 10 for circuit board finished products, when the plate moving device 300 moves down excessively, since the power output end of the elastic support device 400 is elastically in contact with the corresponding tray 200, the power output end of the elastic support device 400 can compress its volume, so that the top tray 200 moves down a certain distance, thereby avoiding the violent collision between the circuit board finished products on the plate moving device 300 and the tray 200 or the circuit board finished products on the tray 200, and then improving the qualified rate of the circuit board finished products. Moreover, since the top tray 200 is spaced from the adjacent tray 200, i.e., the second-layer tray 200, contact between the top tray 200 and the second-layer tray 200 is avoided, thereby avoiding the collision between the top tray 200 and the second-layer tray 200 when the top tray 200 moves down, and further avoiding the problem of the tray group 200a being scattered when the plate moving device 300 places the plate, so as to ensure the normal subsequent operation of the automatic loader 10 for circuit board finished products.

[0059] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
