Abstract
Description
Technical Field
[0001] This utility model relates to a device for transferring circuit boards. Background Technology
[0002] Circuit board functional testing is a testing process for printed circuit boards in the electronics manufacturing industry. It aims to verify whether the entire circuit system on the circuit board is working properly according to the design specifications. This test is crucial for ensuring product quality, reliability, and performance.
[0003] In existing circuit board testing machines, the loading area is usually a loading conveyor belt. Before testing, operators use a trolley to push the cleaned circuit boards to the side of the loading conveyor belt. Then, the operators move the stacks of circuit boards to be tested from the trolley onto the loading conveyor belt. This method of transferring circuit boards is labor-intensive, which reduces the overall testing efficiency of the circuit boards. Moreover, the circuit boards are easily bumped and damaged during the handling process, resulting in defective products and increased costs. Utility Model Content
[0004] The purpose of this invention is to provide a device for transferring circuit boards to solve at least one of the above-mentioned technical problems.
[0005] According to one aspect of the present invention, an apparatus for transferring circuit boards is provided, comprising:
[0006] The conveying device includes multiple parallel and rotatable rollers and a motor, with the motor driving the rollers to rotate.
[0007] The drive unit drives the conveyor to move up and down.
[0008] The detection component is located below the conveying device. When the carrying roller on the external trolley is pushed above the roller, the front end of the trolley can abut against the detection component and trigger the detection component.
[0009] A locking component is located below the conveying device. The locking component includes a driving component and a locking rod. The driving component drives the locking rod to rotate.
[0010] When the detection component is triggered, the drive component drives the locking lever to rotate, locking the front end of the trolley; and
[0011] Support legs allow for adjustment of the height of the conveyor.
[0012] This utility model discloses a device for transferring circuit boards. The operator first places multiple stacks of circuit boards to be tested onto a trolley. The trolley is equipped with multiple parallel support rollers, the distance between two adjacent support rollers being greater than the diameter of a roller. The operator then pushes the trolley towards a conveying device, with the support rollers on the trolley positioned above the rollers of the conveying device. When the front end of the trolley abuts against a detection component, the detection component is triggered. At this point, the support rollers on the trolley and the roller are longitudinally staggered. When the detection component is triggered, a drive component drives a locking rod to rotate, locking the front end of the trolley. The trolley is then fixed in place and cannot move. Then, under the action of the drive component, the roller on the conveying device moves upward. Because the support rollers and the roller are longitudinally staggered and the distance between two adjacent support rollers is greater than the diameter of the roller, the roller moves upward through the gap between two adjacent support rollers on the trolley and supports the circuit boards on the support rollers. As the roller continues to move upward, the circuit boards on the support rollers are transferred to the roller. When the bottom of the roller is high... When the circuit board is at the top of the support roller, the motor drives the roller to rotate, and the rotating roller conveys the circuit board to be tested to the loading area of the circuit board testing machine. Then, the drive component drives the locking rod to rotate in the opposite direction to unlock the front end of the trolley and pull the trolley out. When all the circuit boards on the roller have been conveyed to the loading area of the circuit board testing machine, the drive device drives the roller on the conveyor to move downward to prepare for the next transfer of the circuit board to be tested. The operator can adjust the height of the conveyor by using the support feet according to the height of the support roller on the trolley, thereby adjusting the height of the roller to ensure that the support roller on the trolley is above the roller when the trolley is pushed to the conveyor. The entire process of transferring the circuit board from the external trolley to the loading area of the circuit board testing machine does not require manual handling. This can avoid the circuit board being bumped and damaged during manual transfer, ensuring the quality of the circuit board, reducing the labor intensity of the operators, and improving the transfer efficiency of the circuit board, thereby effectively improving the overall testing efficiency of the circuit board.
[0013] Furthermore, it also includes a U-shaped support with an open side, on which the conveying device slides. The detection components are two contact switches mounted on the U-shaped support. A locking component is also mounted on the U-shaped support between the two detection components. Support legs are located at the bottom of the U-shaped support.
[0014] When both detection components are triggered simultaneously, the drive component drives the locking lever to rotate and lock the front end of the external trolley.
[0015] Therefore, the operator pushes the trolley from the open part of the U-shaped bracket towards the conveying device. When both ends of the front end of the trolley simultaneously abut against the two contact switches, the two contact switches are triggered at the same time. At this time, the drive component drives the locking rod to rotate to lock the front end of the trolley, fixing the trolley in place so that it cannot move. Then, under the action of the drive component, the roller on the conveying device moves upward. The roller moves upward through the gap between two adjacent support rollers and supports the circuit board on the support roller. As the roller continues to move upward, the circuit board on the support roller is transferred to the roller. When the bottom of the roller is higher than the top of the support roller, the motor drives the roller to rotate. The rotating roller can then convey the circuit board. The locking rod will only lock the front end of the trolley when both detection components are triggered simultaneously. If the two detection components are not triggered simultaneously, it means that the trolley is pushed in at an angle. When the trolley is pushed in at an angle, the roller cannot move upward through the gap between two adjacent support rollers on the trolley, and the roller will interfere with the support roller. The setting of the two detection components ensures that the locking rod will only lock the front end of the trolley after it has been pushed in correctly.
[0016] Furthermore, it also includes two mounting plates, the outer ends of which are both mounted on a U-shaped bracket. The two mounting plates are arranged longitudinally, and the two detection components are located between the two mounting plates. The inner ends of the mounting plates are provided with guide plates, which are arranged at an obtuse angle to the mounting plates.
[0017] Therefore, when the external trolley is correctly pushed in, the front end of the trolley is located between the two mounting plates. During the process of pushing the trolley in, as long as the front end of the trolley is located between the two guide plates, the front end of the trolley can be accurately pushed between the two mounting plates so that both ends of the front end of the trolley can trigger the two detection components at the same time. The guide plates can guide the front end of the trolley to be smoothly pushed between the two mounting plates so as to trigger the two detection components at the same time.
[0018] Furthermore, the distance between the two mounting plates is greater than the width of the front end of the outer trolley.
[0019] Therefore, the distance between the two mounting plates can be slightly greater than the width of the front end of the outer trolley, ensuring that the front end of the trolley can be smoothly pushed between the two mounting plates, and that the front end of the trolley is not pushed tilted between the two mounting plates. If the front end of the trolley is pushed tilted between the two mounting plates, the roller cannot move upward from the gap between the two adjacent support rollers on the trolley, and the roller will interfere with the support roller.
[0020] Furthermore, it also includes a support plate and guide columns. The driving device is a motor. The conveying device is located on the top of the support plate. The guide columns are located on the U-shaped bracket and arranged longitudinally. The bottom of the support plate slides on the guide columns. The driving device drives the support plate to move up and down.
[0021] Therefore, the drive unit can drive the conveying device to move up and down through the support plate. The bottom of the support plate slides on the guide column to ensure that the conveying device can move up and down smoothly.
[0022] Furthermore, the U-shaped support includes a connecting frame, a left side frame, and a right side frame, which are connected sequentially to form a U-shaped support with an open side.
[0023] The conveying device, detection components, and locking components are all located on the connecting frame.
[0024] Therefore, the left side frame, connecting frame, and right side frame connected in sequence can be used to support the conveying device and can also form a U-shaped support with open sides for the trolley to be pushed in.
[0025] Furthermore, the driving component is a rotary telescopic cylinder, which drives the locking rod to rotate and move horizontally.
[0026] When the detection component is triggered, the rotary telescopic cylinder drives the locking rod to rotate and move horizontally so that the locking rod snaps outward onto the external trolley.
[0027] Therefore, when both ends of the front end of the trolley simultaneously abut against the two detection components, it indicates that the trolley has been correctly pushed in. At this time, the drive rod of the rotary telescopic cylinder drives the locking rod to rotate a certain angle (such as 90 degrees), and then the drive rod of the rotary telescopic cylinder retracts, so that the locking rod can be fastened outward to the trolley to complete the fixation of the trolley. When unlocking is required, the drive rod of the rotary telescopic cylinder extends, and then the drive rod of the rotary telescopic cylinder drives the locking rod to rotate in the opposite direction by a certain angle (such as 90 degrees), at which point the trolley can be pulled out.
[0028] Furthermore, it also includes a switch, which is electrically connected to the drive component.
[0029] Therefore, when it is necessary to unlock the trolley, the operator can press the switch. After the switch is pressed, the drive rod of the telescopic cylinder extends, and then the drive rod of the telescopic cylinder drives the locking rod to rotate in the opposite direction by a certain angle, thus unlocking the trolley.
[0030] Furthermore, there are two guide pillars, which are arranged in parallel, and the bottom of the bearing plate slides on the two guide pillars.
[0031] Therefore, the two guide columns ensure that the conveying device moves smoothly up and down. Attached Figure Description

[0038] See Figures 1 to 3 An apparatus for transferring circuit boards includes a conveying device 1, a driving device 2, a detection component 3, a locking component 4, a U-shaped bracket 5, a support leg 51, a mounting plate 6, a bearing plate 7, a guide post 8, and a switch 9.
[0039] See Figures 1 to 3 The conveying device 1 includes multiple parallel rollers 11 and a motor 12. The motor 12 is installed on the side of the conveying device 1. The motor 12 drives the rollers 11 to rotate. The motor 12 can use existing transmission mechanisms (such as synchronous pulley + synchronous belt structure) to drive all rollers 11 to rotate synchronously.
[0040] See Figures 1 to 3 The U-shaped support 5 includes a connecting frame 501, a left frame 502, and a right frame 503. The left frame 502, the connecting frame 501, and the right frame 503 are connected in sequence to form a U-shaped support 5 with an open side.
[0041] Conveying device 1 is slidably mounted on U-shaped support 5. For details, please refer to [link / reference]. Figure 2 and Figure 3 The conveying device 1 is mounted on the top of the bearing plate 7 via a mounting bracket 13. The roller 11 and the motor 12 are both mounted on the mounting bracket 13. A horizontal plate 71 is formed at the bottom of the bearing plate 7. The horizontal plate 71 is sleeved on the guide column 8 via a bushing. The bearing plate 7 can move up and down along the guide column 8. The connecting bracket 501 is generally U-shaped. The top and bottom of the guide column 8 are respectively fixed on the top and bottom of the connecting bracket 501 of the U-shaped bracket 5. The guide columns 8 are arranged longitudinally. In this embodiment, the driving device 2 is a motor. In other embodiments, the driving device 2 can also be a cylinder. The horizontal plate 71 at the bottom of the bearing plate 7 is fixed on the drive shaft of the driving device 2. The driving device 2 can drive the bearing plate 7 to move up and down. The bearing plate 7 can drive the conveying device 1 to move up or down.
[0042] See Figure 2 and Figure 3 In this embodiment, there are two drive devices 2 and two guide columns 8, which are arranged in parallel. The two drive devices 2 can simultaneously drive the support plate 7 to move smoothly up and down along the two guide columns 8, thereby ensuring that the conveying device 1 moves smoothly up and down. In other embodiments, the number of drive devices 2 and guide columns 8 can be adjusted appropriately according to the size of the conveying device 1.
[0043] The detection component 3 is installed below the conveying device 1; specifically, refer to [reference needed]. Figure 1 and Figure 2In this embodiment, the detection components 3 are contact switches, and there are two of them. There are also two mounting plates 6. The outer ends of both mounting plates 6 are fixed to the connecting frame 501 of the U-shaped bracket 5. The two mounting plates 6 are arranged longitudinally and parallel. The two detection components 3 are respectively fixed to the connecting frame 501 of the U-shaped bracket 5, and are located between the two mounting plates 6. The two detection components 3 are close to the two mounting plates 6. Guide plates 61 are formed on the inner ends of the mounting plates 6. The guide plates 61 are arranged at an obtuse angle to the mounting plates 6, and the two guide plates 61 are arranged in a V-shape. The operator pushes an external trolley between the left side frame 502 and the right side frame 503 of the U-shaped bracket 5. When the front end of the trolley is pushed between the two mounting plates 6, the two front ends of the trolley... The ends can simultaneously abut against the two detection components 3. When the two detection components 3 are triggered simultaneously, the locking component 4 locks the front end of the trolley 5, and the trolley is fixed and cannot move. The locking component 4 will only lock the front end of the trolley when the two detection components 3 are triggered simultaneously. If the two detection components 3 are not triggered simultaneously, it means that the trolley is pushed in at an angle. During the process of pushing the trolley in, as long as the two ends of the front end of the trolley are located between the two guide plates 61, the front end of the trolley can be accurately pushed between the two mounting plates 6 so that the two ends of the front end of the trolley can trigger the two detection components 3 simultaneously. The guide plate 61 can guide the front end of the trolley to be smoothly pushed between the two mounting plates 6 so that the two detection components 3 can be triggered simultaneously.
[0044] The distance between the two mounting plates 6 is greater than the width of the front end of the outer trolley. The distance between the two mounting plates 6 only needs to be slightly greater than the width of the front end of the outer trolley to ensure that the front end of the trolley can be pushed smoothly between the two mounting plates 6, and also to ensure that the front end of the trolley is not pushed tilted between the two mounting plates 6. If the front end of the trolley is pushed tilted between the two mounting plates 6, the roller 11 of the conveying device 1 will not be able to move upward from the gap between the two adjacent support rollers on the trolley used to place the circuit board, and the roller 11 will interfere with the support roller on the trolley.
[0045] The locking component 4 is installed below the conveying device 1; specifically, see [reference needed]. Figure 1 and Figure 2 The locking component 4 includes a driving component 41 and a locking rod 42. In this embodiment, the driving component 41 is a rotary telescopic cylinder, which is fixed to the connecting frame 501 of the U-shaped bracket 5. One end of the locking rod 42 is fixed to the driving rod of the rotary telescopic cylinder. The rotary telescopic cylinder and the locking rod 42 are located between the two detection components 3. The rotary telescopic cylinder can drive the locking rod 42 to rotate and move horizontally. Figure 2(In the forward and backward direction), when the two ends of the front end of the external trolley simultaneously abut against the two detection components 3, the two detection components 3 are triggered simultaneously, indicating that the trolley has been pushed in correctly. At this time, the drive rod of the rotary telescopic cylinder drives the locking rod 42 to rotate a certain angle (such as 90 degrees), and then the drive rod of the rotary telescopic cylinder performs a retraction action, so the locking rod 42 can move outward (in the forward and backward direction). Figure 1 The lever 42 is fastened to the trolley in direction A to secure it. When unlocking is required, the drive rod of the telescopic cylinder extends, and then the drive rod of the telescopic cylinder drives the locking rod 42 to rotate in the opposite direction by a certain angle (such as 90 degrees). At this time, the trolley can be pulled out from between the left side frame 502 and the right side frame 503 of the U-shaped bracket 5.
[0046] See Figure 1 and Figure 2 Switch 9 is fixed on the right side frame 503 of U-shaped bracket 5. Switch 9 is connected to drive component 41 through wiring harness. When it is necessary to unlock the trolley, the operator can press switch 9. After switch 9 is pressed, the drive rod of the telescopic cylinder extends. Then, the drive rod of the telescopic cylinder drives the locking rod 42 to rotate in the opposite direction by a certain angle (such as 90 degrees), and the trolley is unlocked.
[0047] In other embodiments, the drive component 41 and the locking rod 42 can also be replaced by a motor and a locking hook. The motor can drive the locking hook to rotate. When the two ends of the front end of the external trolley can respectively abut against the two detection components 3, the motor drives the locking hook to rotate so that the locking hook hooks onto the trolley. When unlocking is required, the motor drives the locking hook to rotate so that the locking hook disengages from the trolley.
[0048] A controller (microcontroller or CPU) can be installed on the U-shaped bracket 5. The motor 12, drive device 2, detection component 3, and drive component 41 are connected to the controller through a wiring harness. When the detection component 3 is triggered, the switch signal generated can be sent to the controller. The working mode of the motor 12, drive device 2, and drive component 41 can be preset by the controller. The controller can control the motor 12, drive device 2, and drive component 41 to work together.
[0049] See Figures 1 to 3 The bottom of the U-shaped bracket 5 is equipped with a support foot 51. The support foot 51 may include a support plate and an adjusting screw. The bottom of the adjusting screw is fixed on the support plate, and the top of the adjusting screw is screwed into the bottom of the U-shaped bracket 5. The bottom of the left frame 502 is equipped with one support foot 51, the bottom of the connecting frame 501 is equipped with two support feet 51, and the bottom of the right frame 503 is equipped with one support foot 51. The height of the roller 11 can be adjusted by the support foot 51 according to the height of the carrying rod on the external trolley, so as to ensure that when the external trolley is pushed towards the conveying device 1, the carrying rod on the trolley can be positioned above the roller 11.
[0050] Figure 4 schematically shown Figure 1 The device shown is in use for transferring circuit boards.
[0051] See Figure 4 The trolley 100 adapted to the device for transferring circuit boards of this utility model is equipped with a plurality of parallel-arranged support rollers 101, the distance between two adjacent support rollers 101 is greater than the diameter of the roller 11, and there is a crossbeam 102 at the front end of the trolley 100.
[0052] See Figures 1 to 4 The present invention relates to a device for transferring circuit boards. Before transporting the circuit boards, the operator places multiple stacks of circuit boards to be tested on the support roller 101 of the trolley 100. The operator then moves the trolley 100 along... Figure 4 The trolley 100 is pushed in the F direction towards the space between the left side frame 502 and the right side frame 503 of the U-shaped bracket 5. The carrying roller 101 on the trolley 100 is located above the roller 11 of the conveying device 1. As the trolley 100 continues to be pushed in, under the guidance of the two guide plates 61, the crossbeam 102 at the front end of the trolley 100 is pushed between the two mounting plates 6. The two ends of the crossbeam 102 at the front end of the trolley 100 simultaneously abut against the two detection components 3. The two detection components 3 are triggered simultaneously. At this time, the carrying roller 101 on the trolley 100 and the roller 11 are aligned longitudinally ( Figure 2 The components (vertical and horizontal) are staggered. When both detection components 3 are triggered simultaneously, the drive rod of the drive component 41 drives the locking rod 42 to rotate a certain angle. Then, the drive rod of the drive component 41 retracts, and the locking rod 42 moves along... Figure 4The F-direction fastener is attached to the crossbeam 102 at the front end of the trolley 100 to secure the trolley 100. Then, under the action of the drive device 2, the roller 11 moves upward. Since the support rollers 101 on the trolley 100 and the roller 11 are staggered in the longitudinal direction and the distance between two adjacent support rollers 101 on the trolley 100 is greater than the diameter of the roller 11, the roller 11 will move upward through the gap between two adjacent support rollers 101 on the trolley 100 and support the circuit board on the support roller 101 on the trolley 100. As the roller 11 continues to move upward, the support rollers 101 on the trolley 100... The multiple stacks of circuit boards are transferred to the roller 11. When the bottom of the roller 11 is higher than the top of the support roller 101 on the trolley 100, the rotating roller 11 can transport the circuit boards under the drive of the motor 12, thereby transporting the circuit boards to be tested to the loading area of the circuit board testing machine. Then, the drive rod of the drive component 41 extends and drives the locking rod 42 to rotate in the opposite direction by a certain angle. At this time, the trolley 100 can be pulled out from between the left side frame 502 and the right side frame 503 of the U-shaped bracket 5. When all the circuit boards on the roller 11 are transported to the loading area of the circuit board testing machine (which can be...), the circuit boards are transported to the loading area of the circuit board testing machine. Let the working time of motor 12 be T. After motor 12 has worked for time T, all the circuit boards on roller 11 can be transported to the loading area of the circuit board testing machine. The drive device 2 drives roller 11 to move downward to prepare for the next transfer of circuit boards to be tested. If the two detection components 3 are not triggered simultaneously during the pushing process of trolley 100, it means that trolley 100 is pushed in at an angle. When trolley 100 is pushed in at an angle, roller 11 of conveying device 1 cannot move upward through the gap between two adjacent bearing rollers 101 on trolley 100. 01 Interference may occur. The setting of the two detection components 3 can ensure that the locking component 4 will lock the crossbeam 102 at the front end of the trolley 100 after the trolley 100 is correctly pushed in. The device for transferring circuit boards of this utility model can transfer circuit boards from the external trolley 100 to the loading area of the circuit board testing machine without the need for operators to handle them. This can avoid the circuit boards from being bumped or damaged during manual transfer, ensuring the quality of the circuit boards, reducing the labor intensity of operators, and improving the transfer efficiency of circuit boards, thereby effectively improving the overall testing efficiency of circuit boards.
[0053] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
