Description

Technical Field

[0001] The present application relates to the field of semiconductor processing technology, and in particular to a transmission mechanism for a water washing machine. Background Art

[0002] SMT (surface mount technology) manufacturing technology is becoming more and more popular. In the SMT manufacturing process, sheet cleaning is a crucial link, which can ensure the quality and reliability of electronic products. In order to meet market demand, SMT sheet cleaning machines came into being.

[0003] In the prior art, common water washers primarily use spraying, ultrasonic waves, and brushing to remove dirt from the surface of printed circuit boards. These machines typically consist of a frame with a cleaning chamber formed within it. A conveyor belt for transporting circuit boards is installed at the bottom of the chamber, and a spray system for cleaning the circuit boards is installed at the top of the chamber. The spray system is connected to a deionized water supply module within the frame. As the printed circuit boards are conveyed by the conveyor belt beneath the spray system, the deionized water jets from the spray system's nozzles brush away residual solder paste and other substances from the printed circuit board surface, effectively cleaning the printed circuit board.

[0004] However, in actual use of the existing water washing machine, the operator needs to place the sheets to be cleaned one by one on the conveyor belt, which is cumbersome and inefficient, and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience and efficiency of operators in using a water washing machine to clean sheet materials, the present application provides a transmission mechanism for a water washing machine.

[0006] The present application provides a transmission mechanism for a washing machine that adopts the following technical solution:

[0007] A transmission mechanism for a washing machine comprises a frame, a mounting frame is provided on the frame for lifting, the mounting frame is located at the feeding end of a conveyor belt on the frame, and a loading bracket for stacking sheet materials is detachably mounted on the mounting frame;

[0008] A first drive unit and a second drive unit are fixedly mounted on the frame, a drive end of the first drive unit is fixedly connected to the mounting frame, and the first drive unit drives the sheets on the loading bracket to move one by one to the feeding end of the conveyor belt;

[0009] An action detection unit for detecting the driving action of the first drive unit is fixedly installed on the frame. The signal output end of the action detection unit is connected to the signal input end of the second drive unit. A push plate is fixedly installed on the driving end of the second drive unit. The second drive unit drives the sheet material on the loading bracket to be transferred to the conveyor belt.

[0010] By adopting the above technical solution, during the actual production and processing process, the operator can pre-stack the sheet materials on the loading bracket. The first drive unit can drive the loading bracket to move down a set distance at a set time interval, so that the sheet materials on the loading bracket are lowered between the push plate and the conveyor belt. After the motion detection unit detects the movement of the loading bracket, it controls the second drive unit to drive the stripper plate to move toward the direction close to the conveyor belt, applying a thrust to the sheet materials so that the sheet materials slide onto the conveyor belt and are transported through the conveyor belt through the spray mechanism in the frame. After the automatic unloading action is completed, the second drive unit drives the push plate to reset, and the first drive unit, the motion detection unit, and the second drive unit cooperate to complete the next round of action. By using the first drive unit, the second drive unit, and the motion detection unit in conjunction with each other, during the actual production and processing process, the operator only needs to pre-stack the sheet materials on the loading bracket and place the loading bracket on the mounting frame to achieve the technical effect of automatic loading. The operator only needs to receive the sheet materials at the discharge end of the conveyor belt. Compared with manual loading by the operator, this can save manpower and improve the convenience and efficiency of the washing machine.

[0011] Preferably, the material loading bracket includes two side plates, and a plurality of protrusions are fixedly mounted on the two side plates, and the protrusions on the two side plates are opposite to each other.

[0012] A clamping groove for clamping the sheet material is formed between any two adjacent protrusions on the same side plate.

[0013] By adopting the above technical solution, both sides of the sheet material can be fixed by the slots between the protrusions, making it convenient for operators to stack the sheet materials on the loading bracket.

[0014] Preferably, the first driving unit includes two servo motors, two transmission screws are rotatably mounted on the frame, the cylinders of the two servo motors are fixedly mounted on the frame, and the driving shafts of the two servo motors are respectively connected to the two transmission screws through couplings;

[0015] Slide tables are respectively installed on the two transmission screw rods, and both sides of the mounting frame are respectively fixedly connected to the two slide tables;

[0016] Two guide rods are fixedly mounted on the frame, rod holes for the guide rods to pass through are respectively opened on both sides of the mounting frame, and both sides of the mounting frame are respectively slidably arranged on the two guide rods.

[0017] By adopting this technical solution, two servo motors simultaneously drive the two drive screws in different directions, simultaneously driving the slides on the two drive screws to move up and down, and thus the mounting frame to move up and down. During the actual feeding process, the two servo motors simultaneously drive the two slides to move down a set distance at set time intervals, allowing the sheets to move one by one between the push plate and the conveyor belt. The two guide rods limit the position and sliding trajectory of the mounting frame, thereby reducing the possibility of positional deviation during the upward and downward movement of the mounting frame.

[0018] Preferably, a plurality of sensing slots are provided on a side wall of one of the side panels away from the conveyor belt, and the plurality of sensing slots correspond to the plurality of card slots respectively; the motion detection unit comprises:

[0019] an ultrasonic distance measuring sensor, fixedly mounted on the frame and disposed toward the side panel provided with the sensing slot, for detecting the distance to the side panel and outputting a sensing distance signal;

[0020] a single chip microcomputer, signal-connected to the signal output terminal of the ultrasonic distance measuring sensor, configured to receive the sensing distance signal and output a control signal when the sensing distance is less than a set value;

[0021] The signal input end of the second driving unit is connected to the signal output end of the single chip microcomputer. The second driving unit receives the control signal and drives the push plate to slide in a direction close to the material loading bracket.

[0022] By adopting the above technical solution, when the two servo motors drive the two slides to move downward, the sensing slots next to the card slots are opposite to the ultrasonic ranging sensor, and the sensing distance measured by the ultrasonic ranging sensor becomes larger. Through comparison by the single-chip microcomputer, it can be determined that the sheet material is between the push plate and the conveyor belt. The single-chip microcomputer outputs a control signal, and the second drive unit drives the push plate to move toward the direction close to the sheet material after receiving the control signal, so that the sheet material slides onto the conveyor belt, and the sheet material is transported to the spray system in the rack via the conveyor belt to complete the cleaning operation of the sheet material.

[0023] Preferably, the second driving unit comprises a telescopic cylinder, a cylinder body of the telescopic cylinder is fixedly mounted on the frame, and a cylinder shaft of the telescopic cylinder is fixedly connected to the push plate.

[0024] By adopting the above technical solution, the telescopic cylinder extends or retracts the cylinder shaft, which can drive the push plate to move toward or away from the sheet material, and the action of pushing the sheet material can be completed when the sheet material moves down between the push plate and the conveyor belt.

[0025] Preferably, a through hole is opened on the frame, and the loading bracket and the two transmission screws are both located in the through hole;

[0026] Limiting grooves are respectively provided on the two inner walls opposite to each other of the through hole, and limiting blocks adapted to the two limiting grooves are respectively fixedly installed on both sides of the push plate, and the two limiting blocks are respectively slidably arranged in the two limiting grooves.

[0027] By adopting the above technical solution, the limit groove can limit the limit blocks on both sides of the push plate, thereby limiting the sliding trajectory of the push plate, ensuring that the push plate slides in a straight line.

[0028] Preferably, two baffles are fixedly mounted on the frame, and the two baffles are respectively mounted above the two conveyor belts;

[0029] The bottoms of the two baffles are respectively formed with inclined slopes, and the two inclined slopes are arranged to be inclined downward in a direction away from the loading bracket.

[0030] By adopting the above technical solution and setting the inclined slope, the occurrence of collision between the sheet material and the baffle during the process of the push plate pushing the sheet material to move onto the conveyor belt can be reduced.

[0031] In summary, the transmission mechanism for a washing machine of the present application has at least one of the following beneficial technical effects:

[0032] 1. During the actual production and processing process, the operator can stack the sheets on the loading bracket in advance, and the first driving unit can drive the loading bracket to move down a set length at a set time interval, so that the sheets on the loading bracket drop down to between the push plate and the conveyor belt; after the motion detection unit detects the movement of the loading bracket, it controls the second driving unit to drive the stripping plate to move in the direction close to the transmission belt, exerting a thrust on the sheet so that the sheet slides onto the conveyor belt, and is transported through the conveyor belt through the spray mechanism in the frame; after completing the automatic unloading action, the second driving unit drives the pushing plate to reset, and the first driving unit, the motion detection unit and the second driving unit cooperate to complete the next round of action; through the mutual coordination and use of the first driving unit, the second driving unit and the motion detection unit, during the actual production and processing process, the operator only needs to stack the sheets on the loading bracket in advance and place the loading bracket on the mounting bracket to achieve the technical effect of automatic loading, and the operator only needs to receive the sheets at the discharge end of the conveyor belt; compared with manual loading by the operator, it can save manpower consumption and improve the convenience and efficiency of the use of the water washing machine;

[0033] 2. By setting the inclined slope, the collision between the sheet material and the baffle can be reduced when the push plate pushes the sheet material to move to the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-2 This application is described in further detail.

[0039] Example

[0040] The embodiment of the present application discloses a transmission mechanism for a washing machine. Figure 1 It mainly includes a frame 1, on which a mounting frame 2 is arranged for lifting and lowering, and the mounting frame 2 is located at the feed end of the conveyor belt 3 on the frame 1, and a loading bracket 4 for stacking sheets is detachably installed on the mounting frame 2 by bolts; a first driving unit 5 and a second driving unit 6 are fixedly installed on the frame 1, and the driving end of the first driving unit 5 is fixedly connected to the mounting frame 2, and the first driving unit 5 drives the sheets on the loading bracket 4 to move one by one to the feed end of the conveyor belt 3; an action detection unit for detecting the driving action of the first driving unit 5 is fixedly installed on the frame 1, and the signal output end of the action detection unit is connected with the signal input end of the second driving unit 6, and a push plate 61 is fixedly installed on the driving end of the second driving unit 6, and the second driving unit 6 drives the sheet material on the loading bracket 4 to be transferred to the conveyor belt 3.

[0041] During the actual production and processing process, the operator can stack the sheet materials on the loading bracket 4 in advance, and the first drive unit 5 can drive the loading bracket 4 to move down a set length at a set time interval, so that the sheet materials on the loading bracket 4 drop to between the push plate 61 and the conveyor belt 3; after the motion detection unit detects the movement of the loading bracket 4, it controls the second drive unit 6 to drive the stripping plate to move toward the direction close to the transmission belt, and applies a thrust to the sheet materials so that the sheet materials slide onto the conveyor belt 3, and are transported through the conveyor belt 3 through the spray mechanism in the frame 1; after completing the automatic unloading action, the second drive unit 6 drives the push plate 61 to reset, and the first drive unit 5, the motion detection unit and the second drive unit 6 cooperate to complete the next round of actions.

[0042] It should be noted that in the embodiment of the present application, a box body 14 is fixedly mounted on the frame 1, the spray system is installed in the box body 14, a feed port 141 and a discharge port are provided on the box body 14, and the conveyor belt 3 passes through the discharge port and the feed port 141.

[0043] By coordinating and utilizing the first drive unit 5, the second drive unit 6, and the motion detection unit, during the actual production process, the operator only needs to stack the sheets on the loading bracket 4 in advance and place the loading bracket 4 on the mounting frame 2 to achieve the technical effect of automatic loading. The operator only needs to receive the sheets at the discharge end of the conveyor belt 3. Compared with manual loading by the operator, this can save manpower and improve the convenience and efficiency of the water washing machine.

[0044] Reference Figure 1 and Figure 2 The loading bracket 4 includes two side panels 41, on which a plurality of protrusions 42 are fixedly mounted, and the protrusions 42 on the two side panels 41 are opposite to each other; a slot 43 for engaging the sheet material is formed between any two adjacent protrusions 42 on the same side panel 41.

[0045] The two sides of the sheet material can be fixed by the clamping grooves 43 between the protrusions 42 , making it convenient for the operator to stack the sheet materials on the loading bracket 4 .

[0046] Reference Figure 1 In the embodiment of the present application, the protrusion 42 is approximately L-shaped. The L-shaped protrusion 42 can limit the side wall of the sheet material, thereby reducing the occurrence of the sheet material detaching from the slot 43.

[0047] Reference Figure 1 The first drive unit 5 includes two servo motors 51, and two transmission screws 52 are rotatably installed on the frame 1. The cylinders of the two servo motors 51 are fixedly installed on the frame 1, and the driving shafts of the two servo motors 51 are connected to the two transmission screws 52 through couplings respectively; slides 53 are respectively installed on the two transmission screws 52, and the two sides of the mounting frame 2 are fixedly connected to the two slides 53 respectively; two guide rods 54 are fixedly installed on the frame 1, and rod holes for the guide rods 54 to pass through are respectively opened on both sides of the mounting frame 2, and the two sides of the mounting frame 2 are respectively slidably set on the two guide rods 54.

[0048] By simultaneously driving the two drive screws 52 in different directions with two servo motors 51, the two slides 53 on the two drive screws 52 can be simultaneously driven up and down, thereby driving the mounting frame 2 up and down. During the actual feeding process, the two servo motors 51 simultaneously drive the two slides 53 to move down a set distance at set time intervals, allowing the sheets to be moved one by one between the push plate 61 and the conveyor belt 3. The two guide rods 54 limit the position and sliding trajectory of the mounting frame 2, thereby reducing the possibility of positional deviation of the mounting frame 2 during the upward and downward movement.

[0049] Reference Figure 2 and Figure 3 , a plurality of sensing slots 44 are provided on the side wall of one side panel 41 away from the conveyor belt 3, and the plurality of sensing slots 44 correspond to the plurality of card slots 43 respectively; the motion detection unit includes: an ultrasonic ranging sensor 7, fixedly mounted on the frame 1, and arranged toward the side panel 41 with the sensing slots 44, for detecting the distance between the side panel 41 and outputting a sensing distance signal; a single chip microcomputer, connected to the signal output end of the ultrasonic ranging sensor 7, for receiving the sensing distance signal and outputting a control signal when the sensing distance is less than a set value; the signal input end of the second drive unit 6 is connected to the signal output end of the single chip microcomputer, and the second drive unit 6 receives the control signal and drives the push plate 61 to slide toward the direction close to the loading bracket 4.

[0050] When the two servo motors 51 drive the two slides 53 to move downward, the sensing slot 44 next to the card slot 43 is opposite to the ultrasonic ranging sensor 7, and the sensing distance measured by the ultrasonic ranging sensor 7 becomes larger. Through comparison by the single-chip microcomputer, it can be determined that the sheet material is between the push plate 61 and the conveyor belt 3. The single-chip microcomputer outputs a control signal, and the second drive unit 6 drives the push plate 61 to move toward the direction close to the sheet material after receiving the control signal, so that the sheet material slides onto the conveyor belt 3, and is transported to the spray system in the frame 1 via the conveyor belt 3 to complete the cleaning operation of the sheet material.

[0051] Reference Figure 1 and Figure 3 The second drive unit 6 includes a telescopic cylinder 62. The cylinder body of the telescopic cylinder 62 is fixedly mounted on the frame 1, and the cylinder shaft of the telescopic cylinder 62 is fixedly connected to the push plate 61. It should be noted that a fixed plate is fixedly mounted on the bottom of the push plate 61, and the cylinder shaft of the telescopic cylinder 62 is fixedly mounted on the fixed plate.

[0052] The telescopic cylinder 62 extends or retracts the cylinder shaft to drive the push plate 61 to move toward or away from the sheet material, and the sheet material can be pushed when the sheet material moves down between the push plate 61 and the conveyor belt 3.

[0053] Reference Figure 1 and Figure 2 A through hole 11 is provided on the frame 1, and the loading bracket 4 and the two transmission screws 52 are located in the through hole 11; limiting grooves 12 are respectively provided on the two opposite inner walls of the through hole 11, and limiting blocks adapted to the two limiting grooves 12 are fixedly installed on both sides of the push plate 61, and the two limiting blocks are respectively slidably set in the two limiting grooves 12.

[0054] The limiting groove 12 can limit the limiting blocks on both sides of the push plate 61, thereby limiting the sliding trajectory of the push plate 61, ensuring that the push plate 61 slides in a straight line.

[0055] Reference Figure 1 Two baffles 13 are fixedly mounted on the frame 1, and the two baffles 13 are respectively mounted above the two conveyor belts 3; the bottoms of the two baffles 13 are respectively formed with inclined slopes, and the two inclined slopes are arranged to be inclined downward in the direction away from the loading bracket 4.

[0056] By setting the inclined slope, the occurrence of collision between the sheet material and the baffle 13 during the process of the push plate 61 pushing the sheet material to move onto the conveyor belt 3 can be reduced.

[0057] The implementation principle of the transmission mechanism for a water washing machine in the embodiment of the present application is as follows: during the actual production and processing process, the operator can stack the sheet materials on the loading bracket 4 in advance, and the first driving unit 5 can drive the loading bracket 4 to move down a set length at a set time interval, so that the sheet materials on the loading bracket 4 are dropped between the push plate 61 and the conveyor belt 3; after the action detection unit detects the action of the loading bracket 4, it controls the second driving unit 6 to drive the stripping plate to move toward the direction close to the conveyor belt, and applies a thrust to the sheet materials so that the sheet materials slide onto the conveyor belt 3, and are transported through the conveyor belt 3 to pass through the spray mechanism in the frame 1, completing the automatic unloading movement. After the operation, the second drive unit 6 drives the push plate 61 to reset, and the first drive unit 5, the motion detection unit and the second drive unit 6 cooperate to complete the next round of action; through the mutual coordination and use of the first drive unit 5, the second drive unit 6 and the motion detection unit, in the actual production and processing process, the operator only needs to stack the sheet materials on the loading bracket 4 in advance, and place the loading bracket 4 on the mounting frame 2 to achieve the technical effect of automatic loading, and the operator only needs to receive the sheet materials at the discharge end of the conveyor belt 3; compared with manual loading by the operator, it can save manpower consumption and improve the convenience and efficiency of the use of the water washing machine.
