Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing and processing technology, and in particular to an ignition module fixture and handling and testing equipment for PCB board testing. Background Technology

[0002] Printed circuit boards (PCBs) are found in almost every electronic device. If a device contains electronic components, they are all mounted on PCBs of varying sizes. In addition to fixing various small components, the main function of a PCB is to provide electrical connections between these components. As electronic devices become more complex, the number of components required naturally increases, and the lines and components on PCBs become increasingly dense. Currently, in the PCB production process, after the PCB is produced from the previous process, it needs to be manually transported to testing equipment for testing. This process has low automation, is time-consuming and labor-intensive, and results in low production efficiency.

[0003] Therefore, there is a need to provide an ignition module fixture for PCB board testing and a handling and testing device to solve the above problems. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an ignition module fixture and handling and testing equipment for PCB board testing, so as to realize the automatic handling and testing of PCB products, improve the efficiency of PCB product testing, and achieve a high degree of automation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an ignition module fixture for PCB board testing, comprising two detachable positioning support blocks arranged opposite to each other; the two positioning support blocks are connected by a positioning support plate, and a limited space for placing the PCB board is formed between the upper surface of the positioning support plate and the two positioning support blocks; one end of the PCB board is inserted into the limited space and extends along a first direction into a conversion module disposed at the end of the limited space, so that the PCB board and the conversion module are connected.

[0006] Furthermore, the fixture also includes a base plate and two limiting components disposed on its upper edge. The two positioning support blocks are detachably disposed on the base plate. The limiting components include limiting seats and limiting pins vertically disposed on their tops. When several ignition module fixtures are stacked, the limiting pins can precisely limit the stacking position of each ignition module fixture, preventing deviations in placement that could cause the stacked ignition modules to tip over and damage the PCB board.

[0007] Furthermore, each of the two positioning support blocks is covered with an openable top cover, and the positioning support plate is provided with several support blocks. When the PCB board is inserted into the limited space formed between the positioning support block and the positioning support plate, the operator can open the top cover to ensure that the PCB board is accurately inserted into the conversion module, making the PCB board position more accurate and the operation simpler; at the same time, the top cover can also provide a certain degree of protection for the PCB board during insertion.

[0008] Furthermore, one side of the top cover, parallel to the length direction of the positioning support block, is connected to the fixture base plate via a hinge, and the other side is locked to the side of the positioning support block closest to that side via a locking bolt. This facilitates the opening and locking of the top cover and makes it easier for operators to work with it.

[0009] A handling and testing device includes an ignition module fixture, a frame, at least one set of lifting components, a handling component, and a testing component. The lifting components include a lifting bracket and a lifting support plate for stacking the ignition module fixtures. The lifting support plate is movable up and down in a direction toward or away from the handling components. The handling component includes a pneumatic gripper to grasp the ignition module fixture and move it to the testing component. The testing component includes a connecting module, and a second connecting end on the connecting module can mate with a first connecting end on a conversion module.

[0010] Furthermore, the lifting assembly also includes a lifting drive unit vertically mounted on top of the lifting bracket, a lifting screw located at the driving end of the lifting drive unit, and a lifting guide rail vertically mounted on the lifting bracket. The lifting support plate is threadedly connected to the lifting screw and slidably mounted on the lifting guide rail via a lifting connecting plate perpendicular to it. Through the cooperation of the lifting drive unit, the lifting screw, and the lifting support plate, the lifting support plate can be automatically raised and lowered to move the ignition module fixture and conversion module placed on it to a designated height that is easy for the transport components to grasp.

[0011] Furthermore, each of the lifting components is equipped with a displacement component at its bottom. The displacement component includes a displacement drive, a drive screw horizontally positioned at its drive end, and a displacement guide rail positioned along a second direction. The displacement drive can drive the drive screw to rotate, causing the lifting component to move back and forth along the displacement guide rail. The displacement components enable automatic loading of several PCBs to be inspected, thereby improving the inspection efficiency of the PCBs.

[0012] Furthermore, the conveying assembly also includes a sliding support plate and a vertically mounted lifting drive unit. The bottom of the sliding support plate is connected to the conveying module at the top of the frame. The driving end of the lifting drive unit passes through the sliding support plate and is provided with a fixing plate. The pneumatic gripper is fixed on the fixing plate. Specifically, the lifting drive unit is a lifting cylinder to drive the pneumatic gripper to move up and down, adjusting its position in the vertical direction to accurately grasp the fixture base plate on which the ignition module fixture and the conversion module are placed.

[0013] Furthermore, the testing components also include a test frame, an adjustment component, and a test platform. The adjustment component includes a displacement module and an adjustment guide rail. The displacement module can drive the test platform to move back and forth along the adjustment guide rail, so that the connection end one of the conversion module can dock or disconnect with the connection end two of the connection module. This enables automatic docking detection between the conversion module and the connection module, further improving the overall automation of the equipment.

[0014] Furthermore, the test fixture is equipped with several connecting brackets around its top perimeter, and each connecting bracket has a positioning sensor on its top. This sensor detects whether the conversion module is properly aligned with the connecting module, ensuring the testing accuracy of the PCB board.

[0015] The beneficial effects of this utility model are:

[0016] 1. The ignition module fixture of this utility model is provided with a conversion module at the tail. The conversion module is pre-written with a program to identify different PCB boards, so that when the PCB board is tested later, its corresponding model can be quickly identified and the PCB board can be automatically detected according to the parameters of each model to determine whether the PCB board is qualified.

[0017] 2. In this utility model, the lifting component, displacement component, handling component and testing component work together to realize the automatic handling and inspection of PCB products, improve the efficiency of PCB product inspection, and achieve a high degree of automation.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] See appendix Figure 4 and 5 A PCB board testing ignition module fixture includes two detachable positioning support blocks 46 arranged opposite to each other; the two positioning support blocks 46 are connected by a positioning support plate 47. The positioning support blocks 46 and the positioning support plate 47 cooperate to support and position the PCB board to be tested. The positioning support blocks 46 are set to be detachable according to different PCB board models, which is convenient for staff to replace in real time and improves the applicability of the ignition module fixture 4.

[0028] The positioning support plate 47 is also detachably connected to the two positioning support blocks 46, making it convenient for staff to disassemble and replace.

[0029] Specifically, each of the two positioning support blocks 46 has a groove along its length that matches the thickness of the positioning support plate 47, so that both sides of the positioning support plate 47 can be inserted into the groove. The positioning support plate 47 can then be locked in the groove with screws to prevent the positioning support plate 47 from detaching from the ignition module fixture 4 during transportation.

[0030] The upper surface of the positioning support plate 47 and the two positioning support blocks 46 form a defined space for placing the PCB board. One end of the PCB board is inserted into the defined space and extends along the first direction into the conversion module 5 located at the tail end of the defined space, so that the PCB board and the conversion module 5 are connected. A conversion module 5 is set at the tail end of the ignition module fixture 4. The conversion module 5 is pre-programmed with a program to identify different models of PCB boards, so that the corresponding model can be quickly identified during subsequent PCB board testing, and the PCB board can be automatically tested for qualification according to the parameters of each model.

[0031] Specifically, the first direction refers to the direction parallel to the width direction of the ignition module fixture 4.

[0032] It also includes a fixture base plate 41 and two limiting components 42 disposed on its upper edge. The two positioning support blocks 46 are detachably disposed on the fixture base plate 41. The limiting component 42 includes a limiting seat 421 and a limiting pin 422 vertically disposed on its top. When several ignition module fixtures 4 are stacked, the setting of the limiting pin 422 can accurately limit the stacking position of each ignition module fixture 4, avoiding the phenomenon that the stacked ignition modules will tip over and cause damage to the PCB board due to deviations in their placement positions.

[0033] In some embodiments, the bottom of the fixture base plate 41 has two positioning holes that are in the same position as the limiting pin 422 and have the same structure. When the multi-layer ignition module fixtures 4 are stacked, the cooperation between the limiting pin 422 and the positioning holes can effectively prevent the positional deviation between the upper and lower layers of ignition module fixtures 4, thereby ensuring that the stacked ignition module fixtures 4 will not collapse during the later movement process.

[0034] Specifically, the two limit pins 422 have the same structure but different dimensions to prevent misalignment and affect the subsequent connection test between the conversion module 5 and the connection module 85, thus ensuring the accuracy of the signal connection between the PCB board and the connection module 85.

[0035] An openable top cover 43 is provided on each of the two positioning support blocks 46, and several support blocks 48 are provided on the positioning support plate 47. When the PCB board is inserted into the limited space formed between the positioning support block 46 and the positioning support plate 47, the operator can open the top cover 43 to ensure that the PCB board is accurately inserted into the conversion module 5, making the position of the PCB board more accurate and the operation simpler; at the same time, the top cover 43 can also provide a certain degree of protection for the insertion of the PCB board.

[0036] Several support blocks 48 can provide support and positioning for the placement of the PCB board.

[0037] The top cover 43 is connected to the fixture base plate 41 via a hinge 44 on one side parallel to the length direction of the positioning support block 46, and is locked to the side of the positioning support block 46 near that side via a locking bolt 45. This facilitates the opening and locking of the top cover 43 and makes it easier for operators to operate.

[0038] When the PCB board is to be placed, the top cover 43 can be flipped open by the hinge, which facilitates the placement operation of the staff. After the PCB board is placed, the top cover 43 is closed, and the staff rotates the locking bolt 45 to fix the top cover 43 to the positioning support block 46, which protects the PCB board placed inside.

[0039] A handling and testing device includes an ignition module fixture 4, a frame 1, at least one set of lifting components 3, a handling component 7, and a testing component 8. The lifting component 3 includes a lifting bracket 31 and a lifting support plate 36 for stacking the ignition module fixture 4. The lifting support plate 36 can move up and down in the direction of approaching or moving away from the handling component 7 to automatically feed the fixture containing the PCB board to be tested, reduce the labor intensity of the workers, and realize overall automation.

[0040] In some embodiments, see Appendix Figure 3 , 6 The lifting component 3 is set with three sets. One set, which is close to the test component 8, is used to initially stack several PCB boards to be tested and adjust the height in real time so that the transport component 7 can accurately grab the ignition module fixture 4 to be tested and put it onto the test component 8 until the last ignition module fixture 4 on the lifting support plate 36 is grabbed and the lifting support plate 36 is reset.

[0041] During the above process, the ignition module fixture 4 on the testing component 8 is picked up one by one by the conveying component 7. After the conversion module 5 and the connection module 85 are docked, the external controller automatically identifies the model of the PCB board and automatically compares it with the qualified parameters to detect whether the current PCB board is qualified. If it is qualified, the conveying mechanism moves the qualified part to the lifting component 3 that is specially placed for qualified products; if it is unqualified, the conveying mechanism moves it to the lifting component 3 that is specially placed for unqualified products, so as to realize the automatic unloading of qualified and unqualified products.

[0042] The handling component 7 includes a pneumatic gripper 75 to grab the ignition module fixture 4 and move it to the test component 8. This eliminates the need for manual handling, reducing the labor intensity of workers and improving handling efficiency.

[0043] See appendix Figure 7 The test component 8 includes a connection module 85, with a second connection terminal 86 on the connection module 85 that can mate with a first connection terminal 6 on the conversion module 5. The tail end of the PCB board placed inside the ignition module fixture 4 mates with the conversion module 5, and the first connection terminal 6 on the conversion module 5 mates with the second connection terminal 86 on the connection module 85. During testing, the connection module 85 can acquire data from the PCB board and transmit it to an external controller. The external controller then compares this data with the corresponding model's qualified parameters to automatically determine whether the current PCB board is qualified. This results in more accurate test results and faster testing speed.

[0044] The lifting assembly 3 also includes a lifting drive 32 vertically mounted on top of the lifting bracket 31, a lifting screw 34 located at the driving end of the lifting drive 32, and a lifting guide rail 33 vertically mounted on the lifting bracket 31. The lifting support plate 36 is threadedly connected to the lifting screw 34 and is slidably mounted on the lifting guide rail 33 via a lifting connecting plate 35 perpendicular to it. Through the cooperation of the lifting drive 32, the lifting screw 34, and the lifting support plate 36, the lifting support plate 36 is automatically raised and lowered to move the ignition module fixture 4 and the conversion module 5 placed on it to a designated height that is easy for the handling assembly 7 to grasp.

[0045] In some embodiments, the lifting drive 32 is a drive motor, which drives the lifting screw 34 to rotate so that the lifting support plate 36, which is threadedly connected to the lifting screw 34, moves up and down under the guidance of the lifting guide rail 33.

[0046] It should be noted that the specific structure of the lifting component 3 is not limited to the cooperation of the lifting drive component 32 and the lifting screw 34 mentioned above. It can also be other known mechanical structures that can drive the lifting support plate 36 to move up and down.

[0047] Each lifting assembly 3 has a displacement assembly 2 at its bottom. The displacement assembly 2 includes a displacement drive 21, a drive screw 22 horizontally disposed at its drive end, and a displacement guide rail 23 disposed along a second direction. The displacement drive 21 can drive the drive screw 22 to rotate, so that the lifting assembly 3 moves back and forth along the displacement guide rail 23. The displacement assembly 2 enables automatic feeding of several PCB boards to be inspected, thereby improving the inspection efficiency of the PCB boards.

[0048] Initially, the displacement component 2 drives the lifting component 3 to move to the PCB board loading area, so that workers or external robots can stack the ignition module fixture 4, which contains the PCB board and connects the PCB board to the conversion module 5, onto the lifting component 3 from bottom to top. Then, the displacement component 2 drives the ignition module fixture 4, which is filled with the PCB board to be tested, to move along the second direction to below the transport component 7, so that the transport component 7 can automatically grab and transport the ignition module fixture 4 without manual operation.

[0049] Specifically, the second direction refers to the direction in which the PCB board moves towards the lifting assembly 3 for feeding; the displacement drive component 21 is a drive motor.

[0050] In some embodiments, the combination of displacement drive 21 and drive screw 22 can also be replaced by a moving module. Any known mechanical structure that can drive the lifting component 3 to move back and forth is acceptable, and will not be elaborated on here.

[0051] The handling assembly 7 also includes a sliding support plate 71 and a vertically mounted lifting drive 72. The bottom of the sliding support plate 71 is connected to the handling module at the top of the frame 1. The driving end of the lifting drive 72 passes through the sliding support plate 71 and is provided with a fixing plate 73. The pneumatic gripper 75 is fixed on the fixing plate 73. The lifting drive 72 is specifically a lifting cylinder to drive the pneumatic gripper 75 to move up and down, adjusting its position in the vertical direction so as to accurately grasp the fixture base plate 41 on which the ignition module fixture 4 and the conversion module 5 are placed.

[0052] See appendix Figure 6 In some embodiments, the conveying assembly 7 further includes a guide post 74, one end of which passes through the sliding support plate 71 and is connected to the upper surface of the fixed plate 73, and the other end extends in a direction away from the sliding support plate 71. The guide post 74 provides guidance for the up-and-down movement of the pneumatic gripper 75, ensuring the stability of the pneumatic gripper 75 in gripping the fixture base plate 41.

[0053] The test assembly 8 also includes a test frame 81, an adjustment assembly 82, and a test platform 83. The adjustment assembly 82 includes a displacement module 821 and an adjustment guide rail 822. The displacement module 821 can drive the test platform 83 to move back and forth along the adjustment guide rail 822, so that the connection end 6 of the conversion module 5 can be docked or disconnected from the connection end 86 of the connection module 85. This enables automatic docking detection between the conversion module 5 and the connection module 85, further improving the overall automation of the equipment.

[0054] See appendix Figure 7 In some embodiments, the bottom of the test platform 83 is slidably connected to the adjustable guide rail 822 via several connecting blocks 84 to avoid interference caused by the movement of the displacement module 821 on the test platform 83.

[0055] The test fixture 81 has several connecting brackets 87 arranged around its top perimeter, and each connecting bracket 87 has a positioning sensor 88 on its top. This sensor checks whether the conversion module 5 is properly aligned with the connecting module 85, ensuring the testing accuracy of the PCB board.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
