DETAILED DESCRIPTION

[0035] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0036] In the present disclosure, an XYZ coordinate system is established for the circuit board loader, wherein the X direction is the left-right direction of the circuit board loader; the Y direction is the front-back direction of the circuit board loader; and the Z direction is the up-down direction of the circuit board loader, with the direction indicated by the Z-direction arrow being up, and the opposite direction being down. Unless otherwise specified, the directional words used, such as "inside and outside", refer to the inside and outside of the outline of the component or structure itself; unless otherwise specified, the terms "first, second" and the like are used to distinguish one element from another, and do not have order or importance. In addition, in the description of the reference figures, the same marks in different figures represent the same elements.

[0037] The first aspect of the present disclosure provides a circuit board loading machine, such as Figures 1 to 9As shown, the material clamp assembly 10, the push plate assembly 20 and the first drive assembly 30 are included, wherein the material clamp assembly 10, the push plate assembly 20 and the first drive assembly 30 are all arranged on the frame 40. The material clamp assembly 10 includes a placement platform 11 and at least two material storage frames 12 arranged on the placement platform 11 and spaced apart along the left-right direction X for storing circuit boards. The first drive assembly 30 is drivingly connected to the placement platform 11 to drive the placement platform 11 and the at least two material storage frames 12 placed on the placement platform 11 to move along the left-right direction X and the up-down direction Z, so as to make any one of the at least two material storage frames 12 relative to the push plate assembly 20 in the front-back direction Y. The push plate assembly 20 is used to push the circuit board out of the material storage frame 12 along the front-back direction Y. After the circuit boards stored in the storage frame 12 opposite to the push plate assembly 20 are used up, the first drive assembly 30 drives the placement platform 11 to move, so that the other storage frames 12 placed on the placement platform 11 are opposite to the push plate assembly 20 in the front-to-back direction Y, and the storage frame 12 that has run out of circuit boards is replaced or reloaded with circuit boards, thereby realizing uninterrupted feeding to the SMT placement machine with high work efficiency.

[0038] In the above-mentioned embodiment, the number of the storage frames 12 can be set according to actual needs. For example, two storage frames 12, three storage frames 12, four storage frames 12, etc. can be arranged at intervals along the left-right direction X on the placement platform 11. The first drive assembly 30 drives the placement platform 11 to move along the left-right direction X and the up-down direction Z, so that the different storage frames 12 placed on the placement platform 11 can be positioned relative to the push plate assembly 20 in the front-back direction Y. The storage frame 12 usually stores multiple circuit boards at intervals along the up-down direction Z, and the placement platform 11 is driven to move along the up-down direction Z by the first drive assembly 30, so that the push plate assembly 20 can push the circuit board in the storage frame 12 corresponding to the push plate assembly 20 out of the storage frame 12, so that the circuit board pushed out of the storage frame 12 by the push plate assembly 20 can be transported to the next station, for example, in an SMT placement machine.

[0039] In addition, with the development of automation, the storage frame 12 placed on the placement platform 11 can be replaced by using an automated trolley and a manipulator arranged on the automated trolley, and at least two storage frames 12 are placed on the placement platform 11 at intervals along the left and right direction X. The manipulator can conveniently take and place the storage frame 12 from above the storage frame 12, thereby meeting the demand for automated taking and placing of the storage frame 12.

[0040] In some embodiments, the first drive assembly 30 includes a first sub-drive assembly 31 and a second sub-drive assembly 32. The first sub-drive assembly 31 is driven and connected to the material clamp assembly 10, and is used to drive the material clamp assembly 10 to move along the up and down direction Z. The second sub-drive assembly 32 is driven and connected to the first sub-drive assembly 31, and is used to drive the first sub-drive assembly 31 to move along the left and right direction X, thereby driving the material clamp assembly 10 to move along the left and right direction X.

[0041] In some embodiments, Figures 1 to 3 As shown, the first sub-drive component 31 can be set in an appropriate form according to actual needs. For example, the first sub-drive component 31 is constructed as a screw slide module 310, the placement platform 11 is fixedly connected to the slide of the screw slide module 310, and the placement platform 11 is driven to move along the up-down direction Z by the screw slide module 310, so that the placement platform 11 and the storage frame 12 placed on the placement platform 11 can be accurately controlled in the up-down direction Z. The circuit board in the storage frame 12 can correspond to the push plate component 20 more accurately, and the push plate component 20 can push the circuit board in the storage frame 12 out of the storage frame 12 more smoothly.

[0042] In addition, the second sub-drive assembly 32 can also be configured in an appropriate form according to actual needs. For example, the second sub-drive assembly 32 can be configured as a first cylinder 320, and the driving end of the first cylinder 320 is drivingly connected to the screw slide module 310 to drive the screw slide module 310 to move along the left and right direction X.

[0043] In the above-mentioned embodiment, the first cylinder 320 is arranged on the frame 40, and the frame 40 includes a second placing table 42. The second placing table 42 is provided with a first guide rail 34, and the first slider 33 is slidably connected to the first guide rail 34. The screw slide module 310 is fixedly connected to the first slider 33, and the driving end of the first cylinder 320 is also connected to the first slider 33. The first cylinder 320 drives the first slider 33 to move along the first guide rail 34 along the left and right direction X, so as to drive the screw slide module 310, the placing platform 11 connected to the screw slide module 310, and the material storage frame 12 placed on the placing platform 11 to move along the left and right direction X, and then the screw slide module 310 drives the placing platform 11 and the material storage frame 12 placed on the placing platform 11 to move along the up and down direction Z. The first cylinder 320 and the screw slide module 310 cooperate with each other so that the material clamping assembly 10 can move along the up and down direction Z and the left and right direction X. The first cylinder 320 is used in conjunction with the first guide rail 34 and the first slide block 33 to drive the material clamp assembly 10 to move along the left-right direction X, so that the positioning is more accurate and reliable.

[0044] In other embodiments not shown in the figure, the second sub-drive assembly 32 can also be constructed as a linear module, and the linear module is arranged on the frame 40. The screw slide module 310 can be directly connected to the slide of the linear module. The linear module drives the screw slide module 310 to move along the left and right direction X to drive the material clamping assembly 10 to move along the left and right direction X.

[0045] In some embodiments, Figures 1 to 7 As shown, in order to keep the material storage frame 12 placed on the placement platform 11 stable when moving with the placement platform 11, the circuit board loading machine also includes a fixing assembly 60, the number of the fixing assembly 60 is the same as the number of the material storage frame 12, and each fixing assembly 60 is used to releasably fix a material storage frame 12. When the material storage frame 12 moves with the placement platform 11, the fixing assembly 60 fixes the material storage frame 12 so that the material storage frame 12 remains stable. When the material storage frame 12 needs to be replaced, the fixing assembly 60 releases the material storage frame 12 to facilitate the replacement of the material storage frame 12.

[0046] like Figure 6 As shown, two material storage frames 12 are placed on the placement platform 11 , and each material storage frame 12 is releasably fixed to the placement platform 11 via a fixing assembly 60 .

[0047] In some embodiments, Figure 6 and Figure 7 As shown, the fixing assembly 60 can be constructed in an appropriate form according to actual needs. For example, the fixing assembly 60 includes a fixed side baffle 61 disposed on the placement platform 11 and a movable side baffle 62 movably disposed on the placement platform 11, the material storage frame 12 is located between the fixed side baffle 61 and the movable side baffle 62, and the movable side baffle 62 moves in a direction toward or away from the fixed side baffle 61 to fix or release the material storage frame 12.

[0048] In some embodiments, the circuit board loader further includes a second drive assembly 70, which is used to drive the movable side baffle 62 to move. The second drive assembly 70 can be arbitrarily configured according to actual needs. For example, the second drive assembly 70 is configured as a slide cylinder 700, which is drivingly connected to the movable side baffle 62 and is used to drive the movable side baffle 62 to move.

[0049] In the above-mentioned embodiment, the slide cylinder 700 can be arranged on the placement platform 11 and the slide cylinder 700 is located on the opposite side of the placement platform 11 where the movable side baffle 62 is located, so as not to affect the placement of the material storage frame 12. The slide cylinder 700 includes a first piston rod 701 and a first cylinder body 702. Both ends of the first piston rod 701 of the slide cylinder 700 are fixed on the placement platform 11. The first cylinder body 702 of the slide cylinder 700 is fixedly connected to the movable side baffle 62. The first cylinder body 702 of the slide cylinder 700 moves along the first piston rod 701 of the slide cylinder 700 in the left-right direction X to drive the movable side baffle 62 to move in the left-right direction X, thereby enabling the movable side baffle 62 to move in the direction toward or away from the fixed side baffle 61. Movement, when the movable side baffle 62 moves toward the fixed side baffle 61 under the drive of the slide cylinder 700, the material storage frame 12 placed between the fixed side baffle 61 and the movable side baffle 62 can be clamped to fix the material storage frame 12 placed between the fixed side baffle 61 and the movable side baffle 62; when the movable side baffle 62 moves away from the fixed side baffle 61 under the drive of the slide cylinder 700, the material storage frame 12 placed between the fixed side baffle 61 and the movable side baffle 62 can be released to facilitate the replacement of the material storage frame 12.

[0050] In some embodiments, a second guide rail 80 is also provided on the placement platform 11, and the second guide rail 80 extends along the left-right direction X. A second slider 90 is provided on the movable side baffle 62, and the second slider 90 is slidably connected to the second guide rail 80, so that the movable side baffle 62 can move along the second guide rail 80, and then the movable side baffle 62 can move stably along the left-right direction X.

[0051] In other embodiments, the second drive assembly 70 may also be configured in other forms, such as an electric push rod, a linear module, etc.

[0052] In some embodiments, Figures 5 to 8 As shown, the material storage frame 12 includes a body 121, and a plurality of storage slots 100 are arranged at intervals along the up-down direction Z on the side wall of the body 121. The storage slots 100 are extended along the front-to-back direction Y to accommodate circuit boards. The storage slots 100 extending along the front-to-back direction Y can facilitate the push plate assembly 20 to push the circuit boards accommodated in the storage slots 100 out of the material storage frame 12.

[0053] In the above embodiment, the body 121 is provided with a plurality of storage slots 100 on both side walls in the left-right direction X, and the storage slots 100 on the two side walls correspond to each other. The circuit board is plugged into the corresponding storage slots 100 on the two side walls.

[0054] In some embodiments, one of the two side walls of the body 121 in the left-right direction X may be configured to be movable along the left-right direction X to change the spacing between the two side walls of the body 121 in the left-right direction X to accommodate circuit boards of different widths.

[0055] Specifically, Fig. 9 As shown, the body 121 may include a frame 121c and a movable plate 121a disposed in the frame 121c, the movable plate 121a can move in the frame 121c along the left-right direction X, a plurality of storage slots 100 are disposed on a side wall of the frame 121c in the left-right direction X, a plurality of storage slots 100 are correspondingly disposed on the side of the movable plate 121a opposite to the side wall of the frame 121c on which the storage slots 100 are disposed, a plurality of guide rods 121b are disposed in the frame 121c, the guide rods 121b extend along the left-right direction X, the movable plate 121a is movably sleeved on the guide rods 121b, and the guide rods 121b are used to guide the movable plate 121a. The movable plate 121a can be lockably connected to the top plate of the frame 121c for fixing the movable plate 121a. A through slot extending along the left-right direction X is provided on the top plate of the frame 121c, and a screw 124 is passed through the through slot on the top plate to be connected to the top of the movable plate 121a. When the movable plate 121a needs to be moved, the screw 124 is loosened, and when the movable plate 121a needs to be fixed, the screw 124 is tightened to fix the movable plate 121a on the top plate of the frame 121c.

[0056] In some embodiments, Figures 4 to 9 As shown, the material storage frame 12 further includes a stopper 122 , and the two ends of the body 121 in the front-to-back direction Y are respectively provided with the stopper 122 , and the stopper 122 is used to releasably stop the circuit board.

[0057] In the above-mentioned embodiment, the stop member 122 can be constructed as a stop shaft, which has a stop portion 122a and an avoidance portion 122b. The stop member 122 is movably arranged on the storage frame 12 along the up and down direction Z so that the stop portion 122a or the avoidance portion 122b is located at the end of the storage slot 100, for stopping or releasing the circuit board.

[0058] In some embodiments, Figures 4 to 8As shown, both ends of the side wall of the frame 121c with the storage tank 100 in the front-to-back direction Y are provided with a through hole penetrating the side wall along the up-down direction Z, one end of the through hole is threadedly connected with a screw plug 123, the screw plug 123 blocks one end of the through hole, and a stop shaft is inserted from the other end of the through hole. The stop shaft can move in the up-down direction Z relative to the frame 121c, and a spring is provided between the stop shaft and the screw plug 123, one end of the spring abuts against the stop shaft, and the other end of the spring abuts against the screw plug 123. When pressure is applied toward the screw plug 123 at the end of the stop shaft away from the spring, the stop shaft moves in the through hole of the side wall of the frame 121c toward the screw plug 123, so that the avoidance portion 122b of the stop shaft is located at the end of the storage slot 100, thereby enabling the circuit board in the storage slot 100 to be pushed out of the storage frame 12 by the push plate assembly 20; when no pressure is applied to the stop shaft toward the screw plug 123, under the action of the spring, the stop shaft moves in the through hole of the side wall of the frame 121c in a direction away from the screw plug 123, so that the stop portion 122a of the stop shaft is located at the end of the storage slot 100, thereby preventing the circuit board from falling out of the storage slot 100.

[0059] In addition, a third cylinder 50 can be arranged on the placement platform 11. The third cylinder 50 can be used to apply pressure toward the piston to the stop shaft. A pressing block 300 is arranged at one end of the second piston rod 51 of the third cylinder 50. The third cylinder 50 moves in the up and down direction Z. When the second piston rod 51 of the third cylinder 50 contracts, the pressing block 300 can press down the stop shaft, so that the stop shaft moves in the direction toward the screw plug 123, so that the avoidance portion 122b of the stop shaft is located at the end of the storage slot 100, so that the push plate assembly 20 can push the circuit board inserted in the storage slot 100 out of the storage frame; when the third cylinder 50 is extended, the pressing block 300 can release the stop shaft, and under the action of the spring between the stop shaft and the screw plug 123, the stop shaft can move in the direction away from the screw plug 123, so that the stop portion 122a of the stop shaft is located at the end of the storage slot 100, so as to block the circuit board and prevent the circuit board from falling out of the storage slot 100.

[0060] In the above-mentioned embodiment, the third cylinder 50 can be constructed as an angle cylinder. When the second piston rod 51 of the angle cylinder is extended, the pressing block 300 arranged in the angle cylinder will rotate to a preset angle and be located on one side of the storage frame 12 in the left-right direction X to facilitate the taking and placing of the storage frame 12. When the second piston rod 51 of the angle cylinder is retracted, the pressing block 300 will rotate to a preset angle and press down on the stop shaft.

[0061] In addition, the push plate assembly 20 can be arranged on the first placement table 41 of the frame 40, so that the push plate assembly 20 is on one side of the material clamp assembly 10 in the front-rear direction Y, and the push plate assembly 20 can be arbitrarily constructed in an appropriate form according to actual needs. For example, the push plate assembly 20 can be constructed as a second cylinder 200, and the driving end of the second cylinder 200 is used to push the circuit board. When the avoidance portion 122b of the stopper shaft on the frame body 121c is located at the end of the storage tank 100, the driving end of the second cylinder 200 can push the circuit board out of the material storage frame 12.

[0062] The present disclosure exemplarily describes the working process of the circuit board loading machine. Figures 1 to 9 As shown, two material storage frames 12 are placed on the placement platform 11 in advance along the left-right direction X. The two material storage frames 12 are fixed by two fixing components 60 respectively, and the two third cylinders 50 are arranged corresponding to the two material storage frames 12. The pressing block 300 of the third cylinder 50 presses down on the stopper shaft of the corresponding material storage frame 12, so that the avoidance portion 122b on the stopper shaft is located at the end of the storage tank 100. One of the two material storage frames 12 is located at a position corresponding to the second cylinder 200. For the convenience of description, this position is defined as a working station. The bottommost circuit board in the material storage frame 12 at the working station corresponds to the second cylinder 200. The driving end of the second cylinder 200 pushes the circuit board out of the material storage frame 12, so that the circuit board is transported to the SMT placement machine. When the bottom layer of the circuit board in the material storage frame 12 at the working station is pushed out, the screw slide module drives the placement platform 11 to move down a preset distance, and the second cylinder 200 pushes out the circuit board adjacent to the bottom layer of the circuit board in the material storage frame 12, and then circulates in sequence until all the circuit boards in the material storage frame 12 at the working station are pushed out. Then the first cylinder 320 drives the placement platform 11 to move along the left-right direction X, and moves the material storage frame 12 with the circuit board to the working station, and then the screw cylinder slide module drives the placement platform 11 to return to the initial height, so that the bottom layer of the circuit board in the material storage frame 12 at the working station corresponds to the second cylinder 200, and the slide cylinder 700 of the fixing assembly 60 for fixing the empty material storage frame 12 moves, so that the movable side baffle 62 moves in the direction away from the fixed side baffle 61 of the fixing assembly 60 to release the empty material storage frame 12. The empty material storage frame 12 is replaced and fixed by the fixing assembly 60, and then the second cylinder 200 continues to push the circuit board in the material storage frame 12 on the working station. The above process is continuously circulated to realize uninterrupted feeding to the SMT placement machine.

[0063] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
