[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] The following is for reference. Figures 1 to 8 This invention describes a circuit board alternating feeding device and control method according to embodiments of the present invention.

[0023] The circuit board alternating feeding device according to a first aspect of the present invention includes an alternating component, a feeding component, and a transfer component.

[0024] The alternating assembly includes two loading bins 100 for placing a batch of circuit boards. The loading bins 100 have multiple placement slots 120 for placing circuit boards 121 from top to bottom. The left and right sides of the loading bins 100 are open, so that the circuit boards can be placed into or taken out of the placement slots 120 from the left and right sides of the loading bins 100.

[0025] Each placement slot 120 has a first laterally extending protruding edge on the bottom front side and a second laterally extending protruding edge on the bottom rear side. When the circuit board is placed in the placement slot 120, the first protruding edge supports the front edge of the circuit board and the second protruding edge supports the rear edge of the circuit board, so that the circuit board can be stably placed in the placement slot 120. Through the first and second protruding edges that are spaced apart, there is a certain gap between the first and second protruding edges, so that the pneumatic grippers of the circuit board processing equipment can grip the left edge of the circuit board from left to right, and it is also convenient for the staff to insert the circuit board into the placement slot 120 from right to left.

[0026] Among them, reference Figure 6 The material feeding box 100 is equipped with a vertically arranged movable plate 110. The movable plate 110 is slidably disposed in the material feeding box 100 in the front-to-back direction. The movable plate 110 and the material feeding box 100 can be slidably connected by a guide rail slider. All first protrusions are fixedly disposed on the rear side of the movable plate 110, and all second protrusions are fixedly disposed on the rear wall of the material feeding box 100. In this way, by adjusting the front-to-back position of the movable plate 110, the front-to-back size of the placement slot 120 can be changed to accommodate circuit boards of different specifications and increase the applicability range. Furthermore, the slider connecting the movable plate 110 and the material feeding box 100 can be a locking slider. The locking slider is a conventional component in this field, and its specific structure will not be described in detail here. The locking slider is equipped with a locking handle. After the movable plate 110 is adjusted to a suitable position, the locking handle can be operated to fix the lateral position of the locking slider, so as to prevent the movable plate 110 from deviating from its original position due to vibration during equipment operation.

[0027] The feeding assembly is used to sequentially deliver the circuit boards in the feeding box 100 to the loading station of the processing equipment; see reference. Figure 2The feeding assembly includes a feeding base 200 and a feeding lifting seat 220 that is vertically slidably disposed on the feeding base 200. The feeding base 200 can be fixedly disposed on the ground. The feeding base 200 and the feeding lifting seat 220 can be slidably connected by a guide rail slider mechanism, a slide bar mechanism or other suitable mechanism. The feeding base 200 is provided with a first driver 210 for driving the feeding lifting seat 220 to rise and fall. The first driver 210 can be a linear motor, an electric push rod or other suitable linear driver. The feeding lifting seat 220 is provided with a horizontally disposed feeding conveyor belt 221. The feeding conveyor belt 221 is used to move the discharge box 100 to the upper side of the feeding lifting seat 220 or to send the discharge box 100 away from the upper side of the feeding lifting seat 220. The upper left side of the feeding lifting seat 220 is provided with a feeding limit baffle, which can limit the left limit position of the discharge box 100 located on the upper side of the feeding lifting seat 220.

[0028] The feeding lifting platform 220 has a first feeding position 261 and a second feeding position 262 located above the first feeding position 261. The distance between the first feeding position 261 and the second feeding position 262 is greater than the vertical dimension of the material box 100. The upper sides of the first feeding position 261 and the second feeding position 262 are respectively provided with a first feeding space and a second feeding space for placing the material box 100. The top of the first feeding space is provided with a loading station for loading processing equipment. (Refer to...) Figure 7 The feeding base 200 is open on the left side corresponding to the loading station, so that the pneumatic gripper of the circuit board processing equipment can pass through the feeding base 200 from left to right and extend to the loading station to grip the circuit board.

[0029] Reference Figure 1 and Figure 3 The transfer assembly includes a first conveyor belt 310 located to the right of the first feeding position 261 and a second conveyor belt 320 located to the right of the second feeding position 262. The first conveyor belt 310 and the second conveyor belt 320 are arranged laterally. The conveying direction of the first conveyor belt 310 is to the left, and the conveying direction of the second conveyor belt 320 is to the right. The first conveyor belt 310 is used to send one of the discharge boxes 100 into the first feeding space, and the second conveyor belt 320 is used to convey the other discharge box 100 away from the second feeding space.

[0030] It is understandable that when the feeding box 100 is placed on the upper side of the conveyor belt, there is friction between the feeding box 100 and the conveyor belt, which allows the conveyor belt to transport the feeding box 100. This results in the first conveyor belt 310 not being able to completely feed the feeding box 100 into the first feeding space, and the second conveyor belt 320 not being able to feed the feeding box 100 out of the second feeding space. Therefore, the present invention provides a feeding conveyor belt 221 to realize the complete feeding of the feeding box 100 into the first feeding space and the feeding of the feeding box 100 out of the second feeding space.

[0031] In use, two feeding bins 100 are placed on the first conveyor belt 310 and the second conveyor belt 320 respectively. The feeding bin 100 placed on the first conveyor belt 310 already contains multiple circuit boards. The feeding lift 220 moves to the first feeding position 261. The first conveyor belt 310 and the feeding conveyor belt 221 transport the feeding bin 100 containing the circuit boards to the first feeding space. The first driver 210 drives the feeding lift 220 to rise, so that multiple circuit boards move sequentially to the loading station for processing by the processing equipment. After the circuit boards in the feeding bin 100 are used up, the first driver 210 drives the feeding lift 220 to rise. The lowering seat 220 moves to the second feeding position 262, and the second conveyor belt 320 and the feeding conveyor belt 221 transport the empty feeding box 100 to the second conveyor belt 320. During this period, when the feeding box 100 containing circuit boards rises in the feeding base 200, the operator can use this time to put multiple circuit boards into another feeding box 100. After putting the circuit boards in, the feeding box 100 is moved to the first conveyor belt 310, and the cycle continues. By alternating the use of the two feeding boxes 100, the operator can put multiple circuit boards in at one time, reducing manpower consumption, and the circuit board processing equipment can still maintain continuous production.

[0032] In some embodiments of the present invention, the circuit board alternating feeding device further includes a receiving assembly for conveying the unloading box 100 located on the second conveyor belt 320 to the first conveyor belt 310. The receiving assembly includes a receiving base 400 and a receiving lifting seat 420 slidably disposed vertically on the receiving base 400. The receiving base 400 can be fixedly disposed on the ground. The receiving base 400 and the receiving lifting seat 420 can be slidably connected by a guide rail slider mechanism, a slide bar mechanism, or other suitable mechanism. The receiving base 400 is provided with a receiving lifting mechanism for controlling the lifting of the receiving lifting seat 420. The material lifting seat 420 is provided with a transversely arranged receiving conveyor belt 421, which is used to move the discharge box 100 to the upper side of the receiving lifting seat 420 or to send the discharge box 100 away from the upper side of the receiving lifting seat 420. The upper right side of the receiving lifting seat 420 is provided with a receiving limit baffle, which can limit the right limit position of the discharge box 100 located on the upper side of the receiving lifting seat 420. The lifting of the receiving lifting seat 420 has a first receiving position 461 located on the right side of the first conveyor belt 310 and a second receiving position 462 located on the right side of the second conveyor belt 320.

[0033] In use, the receiving lifting seat 420 is located at the second receiving position 462. The second conveyor belt 320 and the receiving conveyor belt 421 can transport the empty material box 100 to the upper side of the second receiving position 462. At this time, the operator can put the circuit board into the empty material box 100 from the right side of the receiving assembly. After placement, the receiving lifting seat 420 moves down to the first receiving position 461. Then, the first conveyor belt 310 and the receiving conveyor belt 421 send the material box 100 containing the circuit board to the first conveyor belt 310, ready to be sent to the feeding assembly. Then, the receiving lifting seat 420 moves up to the second receiving position 462, ready to receive the empty material box 100 sent from the second conveyor belt 320, and so on. This eliminates the need for the operator to move the material box 100 from the second conveyor belt 320 to the first conveyor belt 310, reducing the operator's workload.

[0034] In some embodiments of the present invention, reference is made to... Figure 4 The material receiving lifting mechanism includes a counterweight 431, a first guide wheel 433 rotatably mounted on the material receiving base 400, and a first cable 432 passing over the upper side of the first guide wheel 433. The two ends of the first cable 432 are respectively connected to the counterweight 431 and the material receiving lifting seat 420. The mass of the counterweight 431 is greater than that of the material receiving lifting seat 420 and less than the sum of the material receiving lifting seat 420 and the material discharging box 100. At the second material receiving position 462, a locking mechanism 450 is connected between the material receiving lifting seat 420 and the material receiving base 400. After the receiving lifting seat 420 moves to the second receiving position 462, the locking mechanism 450 fixes the current position of the receiving lifting seat 420, so that after the material box 100 is conveyed to the material feeding assembly, the receiving lifting seat 420 can still be maintained at the second receiving position 462. This allows the operator sufficient time to put the circuit board into the empty material box 100. After placement, the operator operates the locking mechanism 450 to release the receiving lifting seat 420. Since the mass of the counterweight 431 is less than the sum of the mass of the receiving lifting seat 420 and the mass of the material box 100, the receiving lifting seat 420 can move down to the first receiving position 461. Then, after the material box 100 moves to the first conveyor belt 310, since the mass of the counterweight 431 is greater than the mass of the receiving lifting seat 420, the receiving lifting seat 420 is pulled to the second receiving position 462 by the counterweight 431. The lifting of the receiving lifting seat 420 can be achieved without the need for electrical components. The structure is simple, maintenance is convenient, and the equipment cost is low.

[0035] In some embodiments of the present invention, the locking mechanism 450 includes a wedge 451 and a pin. The wedge 451 is fixedly disposed on the receiving lifting seat 420. The wedge 451 has a top surface that slopes downward from left to right and a bottom surface that is arranged horizontally. The pin is arranged horizontally and slides horizontally on the receiving base 400. The right end of the pin is located outside the receiving base 400. The right end of the pin is provided with a handle. A tension spring sleeved on the outside of the pin is connected between the handle and the receiving base 400, so that when the pin is driven to move to the right relative to the receiving base 400, it tends to move to the left to reset. When the receiving lifting seat 420 is in the first receiving position 461, the left end of the pin is located above the top surface of the wedge 451. When the receiving lifting seat 420 is in the second receiving position 462, the left end of the pin is located below the bottom surface of the wedge 451. After the worker places the circuit board, pulling the handle to the right will disengage the pin from the bottom of the wedge 451, allowing the receiving lifting seat 420 to move down from the second receiving position 462. The worker can then release the handle. When the receiving lifting seat 420 rises from the first receiving position 461, the pin is pushed to the right by the top surface of the wedge 451. When the receiving lifting seat 420 moves to the second receiving position 462, the wedge 451 moves above the pin, and the pin, under the action of the tension spring, moves to the left and resets to abut against the bottom of the wedge 451, thus locking the receiving lifting seat 420. Similarly, locking and unlocking the receiving lifting seat 420 can be achieved without the need for electrical components.

[0036] In other embodiments of the present invention, reference is made to Figure 5 The material receiving lifting mechanism includes a second cable 442 and a second guide wheel 443 rotatably mounted on the material receiving base 400. The material feeding base 200 is rotatably mounted with a third guide wheel 444. The second cable 442 passes over the upper side of the second guide wheel 443 and the third guide wheel 444. Both ends of the second cable 442 are provided with abutment blocks 441. The two abutment blocks 441 abut against the material receiving lifting seat 420 and the material feeding lifting seat 220 from bottom to top, respectively. At the second material receiving position 462, a locking mechanism 450 is connected between the material receiving lifting seat 420 and the material receiving base 400. The second cable 442, the second guide wheel 443, and the third guide wheel 444 can each be two, and are respectively set on the front and rear sides of the receiving base 400. The abutment block 441 can be a rod extending back and forth. The two abutment blocks 441 respectively cross the bottom of the receiving lifting seat 420 and the feeding lifting seat 220. The two ends of the abutment block 441 are respectively connected to the two cables. In this way, the receiving lifting seat 420 and the feeding lifting seat 220 are subjected to balanced forces and the structure is stable.

[0037] After the empty discharge bin 100 moves from the feeding assembly to the second conveyor belt 320, the descent of the feeding lift 220 will pull the second cable 442, causing the receiving lift 420 to rise. When the discharge bin 100 containing the circuit board moves from the first conveyor belt 310 to the feeding assembly, the rise of the feeding lift 220 will not pull the second cable 442, and the second cable 442 will not pull the receiving lift 420 down, allowing sufficient time for workers to add electrical circuits to the empty discharge bin 100. After the road plate is placed, the locking mechanism 450 is operated to release the receiving lifting seat 420. Compared with using the counterweight block 431, the receiving lifting seat 420 is raised faster by using the descent of the feeding lifting seat 220. The receiving lifting seat 420 can be moved to the second receiving position 462 before the second conveyor belt 320 moves the empty feeding box 100 to its right end. There is no need to interrupt the start of the second conveyor belt 320. The operation of the circuit board alternating feeding device is smoother and the failure is reduced.

[0038] In some embodiments of the present invention, a damper is connected between the receiving lifting seat 420 and the receiving base 400. The damper is used to control the lifting speed of the receiving lifting seat 420 to ensure smooth lifting. By setting the damper, the receiving lifting seat 420 is prevented from falling too fast, which could lead to a violent collision, thereby preventing damage to the receiving assembly or the discharge box 100. The damper can be a damping slide rail, which can serve as a sliding connection between the receiving lifting seat 420 and the receiving base 400 while providing damping force. In other embodiments of the present invention, the first cable 432 / second cable 442 can also be a chain, the guide wheel can be a sprocket, and the damper can be a rotational damper connected between the sprocket and the receiving base 400.

[0039] In some embodiments of the present invention, the first driver 210 is a linear motor. This structure is reasonable and compact, and facilitates control of the height position of the feeding lifting seat 220.

[0040] In some embodiments of the present invention, a second clutch mechanism is provided between the receiving assembly and the transfer assembly. The second clutch mechanism includes a fourth clutch 540 linked to the receiving conveyor belt 421, a fifth clutch 550 linked to the first conveyor belt 310, and a sixth clutch 560 linked to the second conveyor belt 320. At the first receiving position 461, the fourth clutch 540 is connected to the fifth clutch 550, and at the second receiving position 462, the fourth clutch 540 is connected to the sixth clutch 560. Thus, the receiving conveyor belt 421 can be driven by the first conveyor belt 310 and the second conveyor belt 320 without the need for additional electrical components to drive it. The fourth clutch 540, the fifth clutch 550, and the sixth clutch 560 can all be gears. The conveyor belt includes two rollers and a belt body. The gear can be set on one of the rollers to achieve linkage with the conveyor belt. When the receiving lifting seat 420 is in the first receiving position 461, the fourth clutch 540 is located to the right of the fifth clutch 550 and they are meshed, which can achieve linkage between the receiving conveyor belt 421 and the first conveyor belt 310. When the receiving lifting seat 420 is in the second receiving position 462, the fourth clutch 540 is located to the right of the sixth clutch and they are meshed, which can achieve linkage between the receiving conveyor belt 421 and the second conveyor belt 320.

[0041] In other embodiments of the present invention, the fifth clutch 550 may be located obliquely below the roller of the first conveyor belt 310 and linked with it via a pulley mechanism or other suitable linkage mechanism; the sixth clutch 560 may be located obliquely above the roller of the second conveyor belt 320 and linked with it via a pulley mechanism or other suitable linkage mechanism; when the receiving lifting seat 420 is in the first receiving position 461, the fourth clutch 540 is located above the fifth clutch 550 and meshes with it; when the receiving lifting seat 420 is in the second receiving position 462, the fourth clutch 540 is located below the sixth clutch and meshes with it; in this way, the engagement and disengagement of the fourth clutch 540 with the fifth clutch 550 and with the sixth clutch 560 are both radial movements, which helps to reduce gear wear.

[0042] In some embodiments of the present invention, a first clutch mechanism is provided between the feeding assembly and the transfer assembly. The first clutch mechanism includes a first clutch element 510 linked to the feeding conveyor belt 221, a second clutch element 520 linked to the first conveyor belt 310, and a third clutch element 530 linked to the second conveyor belt 320. At the first feeding position 261, the first clutch element 510 is connected to the second clutch element 520, and at the second feeding position 262, the first clutch element 510 is connected to the third clutch element 530. In this way, the feeding conveyor belt 221 can be driven by the first conveyor belt 310 and the second conveyor belt 320 without the need for additional electrical components to drive the feeding conveyor belt 221. The structure of the first clutch mechanism can be the same as that of the second clutch mechanism, and will not be described in detail here.

[0043] In some embodiments of the present invention, reference is made to... Figure 8 The first conveyor belt 310 and the second conveyor belt 320 are active conveyor belts, while the receiving conveyor belt 421 and the feeding conveyor belt 221 are both driven conveyor belts. In this way, the receiving conveyor belt 421 and the feeding conveyor belt 221 do not require electrical components for driving, resulting in a simple structure, convenient maintenance, and low equipment cost.

[0044] In some embodiments of the present invention, the first conveyor belt 310, the second conveyor belt 320, the feeding lifting seat 220, and the receiving lifting seat 420 are respectively provided with front side baffles 331 on their upper front sides, and the first conveyor belt 310, the second conveyor belt 320, the feeding lifting seat 220, and the receiving lifting seat 420 are respectively provided with rear side baffles 332 on their upper rear sides to prevent the material box 100 from deviating forward or backward during lateral movement; the left edge of the front side of the material box is provided with a left front guide surface that slopes backward from right to left, the right edge of the front side of the material box is provided with a right front guide surface that slopes backward from left to right, the left edge of the rear side of the material box is provided with a left rear guide surface that slopes forward from right to left, and the right edge of the rear side of the material box is provided with a right rear guide surface that slopes forward from left to right; in this way, during the process of the material box transitioning laterally from one conveyor belt to another, even if the material box has a certain forward or backward deviation, causing the guide surface to touch the edge of the side baffle, the guide surface can correct the material box back to its original path and prevent the material box from getting stuck.

[0045] The control method of the second aspect of the present invention is applied to the above-described circuit board alternating feeding device, with reference to Figure 9 The control method includes the following steps: In step S100, when the feeding lifting seat 220 moves to the first feeding position 261, the first conveyor belt 310 is started, and the material box 100 is moved from the first conveyor belt 310 to the upper side of the feeding lifting seat 220.

[0046] Specifically, a first proximity sensor can be installed on the feeding base 200 to detect the bottom of the feeding lifting seat 220 when it is located at the first feeding position 261, so as to determine whether the feeding lifting seat 220 has moved to the first feeding position 261; a second proximity sensor can be installed on the feeding base 200 to detect the left end of the discharge box 100 when it is located in the first feeding space, so as to determine whether the discharge box 100 has moved to the upper side of the feeding lifting seat 220.

[0047] In step S200, when the material box 100 arrives at the feeding lifting seat 220, it is determined whether there is a circuit board at the loading station and whether the feeding lifting seat 220 has moved to the second feeding position 262. When there is no circuit board at the loading station and the feeding lifting seat 220 has not moved to the second feeding position 262, the first driver 210 is controlled to drive the feeding lifting seat 220 to rise.

[0048] When the material box 100 is located in the first feeding space, the height of the loading station is higher than the placement slot 120 at the top, so that the material box 100 needs to rise a certain distance before a circuit board moves to the loading station. In step S200, a third proximity sensor can be set on the feeding base 200 to detect the circuit board located at the loading station to determine whether there is a circuit board at the loading station; a fourth proximity sensor can be set on the feeding base 200 to detect the top of the feeding lifting seat 220 when it is located at the second feeding position 262 to determine whether the feeding lifting seat 220 has moved to the second feeding position 262; whenever a circuit board at the loading station is taken away by the processing equipment, the first driver 210 is controlled to continue to drive the feeding lifting seat 220 to rise until there is a circuit board at the loading station, or until the circuit boards in the material box 100 are used up and the lifting seat moves to the second feeding position 262.

[0049] In step S300, when the feeding lifting seat 220 moves to the second feeding position 262, the second conveyor belt 320 is started to move the discharge box 100 from the upper side of the feeding lifting seat 220 to the second conveyor belt 320.

[0050] A fifth proximity sensor can be installed on the feeding base 200 to detect the right end of the discharge box 100 when it is located in the second feeding space, so as to determine whether the discharge box 100 has moved to the second conveyor belt 320.

[0051] In step S400, the material box 100 leaves the feeding lifting seat 220, and the first driver 210 is controlled to drive the feeding lifting seat 220 to descend to the first feeding position 261.

[0052] In step S500, when the receiving lifting seat 420 moves to the second receiving position 462, the second conveyor belt 320 is started to move the discharge box 100 from the second conveyor belt 320 to the upper side of the receiving lifting seat 420.

[0053] A sixth proximity sensor can be installed on the second conveyor belt 320 to detect the bottom of the receiving lifting seat 420 when it is located at the second receiving position 462, so as to determine whether the receiving lifting seat 420 has moved to the second receiving position 462; a seventh proximity sensor can be installed on the right end of the second conveyor belt 320 to detect the discharge box 100, so as to determine whether the discharge box 100 has moved to the upper side of the receiving lifting seat 420.

[0054] After performing step S500, the operator can put the circuit board into the material box 100 located on the upper side of the receiving lifting seat 420, and then control the locking mechanism 450 to release the receiving lifting seat 420, so that the receiving lifting seat 420 can descend, so that the circuit board alternating feeding device can perform the subsequent step S600.

[0055] In step S600, when the receiving lifting seat 420 moves to the first receiving position 461, the first conveyor belt 310 is started to move the discharge box 100 from the upper side of the receiving lifting seat 420 to the first conveyor belt 310.

[0056] An eighth proximity sensor can be installed on the first conveyor belt 310 to detect the top of the receiving lifting seat 420 when it is located at the first receiving position 461, so as to determine whether the receiving lifting seat 420 has moved to the first receiving position 461; a ninth proximity sensor can be installed on the first conveyor belt 310 to detect the left end of the discharge box 100 when it is located at the right end of the first conveyor belt 310, so as to determine whether the discharge box 100 has moved to the first conveyor belt 310.

[0057] In this way, the sensors are all installed on the feeding base 200, the first conveyor belt 310, or the second conveyor belt 320, eliminating the need for electrical components on moving parts such as the feeding lift 220, the receiving lift 420, and the unloading bin 100. This reduces wiring, simplifies the structure, and facilitates subsequent maintenance and repair. By setting a control method to control the circuit board alternating feeding device, the two unloading bins 100 can move to the feeding assembly in an orderly and alternating manner. Workers can put multiple circuit boards into the unloading bins 100 at once from the unloading assembly, reducing manpower consumption while maintaining continuous production of the circuit board processing equipment.

[0058] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
