Description

Technical Field

[0001] This application relates to the technical field of testing equipment, and in particular to a feeding module for a board-to-board connector testing equipment. Background Technology

[0002] Board-to-board connectors are electronic components designed to establish direct, pluggable electrical and mechanical connections between two or more printed circuit boards (PCBs). FPC board-to-board connectors are generally mounted on PCBs, and the pins on the board-to-board connectors need to be soldered to the PCBs. The pin precision requirements for board-to-board connectors are very high.

[0003] In the prior art, board-to-board connectors are usually fed by a vibratory feeder.

[0004] Vibratory feeders can screen board-to-board connectors, ensuring that the output of the board-to-board connectors is in a fixed direction. If the angle of the board-to-board connector is incorrect, it needs to be dropped for re-screening. Because the pin precision requirements of board-to-board connectors are very high, with the distance between the pin and the surface of the board-to-board connector and the PCB board being within 10 microns, dropping the board-to-board connector from a height may damage the pins of the board-to-board connector, leading to an increase in the defect rate of the board-to-board connector and affecting the normal testing of the board-to-board connector testing equipment. Summary of the Invention

[0005] To address the issue of vibration feeders causing damage to board-to-board connectors, this application provides a feeding module for a board-to-board connector testing device.

[0006] This application provides a feeding module for a board-to-board connector testing device, which adopts the following technical solution: A feeding module of a board-to-board connector testing device includes a base, an air blowing structure on the base, and a plurality of placement tubes on the base. Board-to-board connectors are placed in the placement tubes, and the air blowing structure is used to blow the board-to-board connectors out of the placement tubes.

[0007] By adopting the above technical solution, the board-to-board connectors are blown out of the placement tube by the air blowing structure, thus realizing the feeding of board-to-board connectors. The gas will not cause the board-to-board connectors to vibrate, so that the board-to-board connectors can move smoothly and avoid high-frequency vibration during feeding. At the same time, since the board-to-board connectors themselves are at a fixed angle in the placement tube, there is no need to re-screen the board-to-board connectors, thus making the board-to-board connectors less prone to damage during feeding.

[0008] Optionally, the base is provided with a storage seat, the storage seat has a storage hole for stacking tubes, the base is provided with a lifting structure, the lifting structure has a lifting plate, the lifting structure is used to push the placement tube to move into the storage hole, and the storage seat is provided with a limiting structure, the limiting structure is used to prevent the placement tube from leaving the storage hole.

[0009] By adopting the above technical solution, the lifting structure drives the lifting plate to rise, allowing the lifting plate to push the placement tube into the storage hole. Then, the lifting structure drives the lifting plate to fall. At this time, the limiting structure can prevent the placement tube from leaving the storage hole, so that the placement tube can be stably stacked in the storage base. This eliminates the need for workers to remove the placement tube again, reducing the number of operation steps for workers and further accelerating the loading speed of board-to-board connectors.

[0010] Optionally, the limiting structure includes a limiting spring and a limiting block. The limiting block is disposed on the limiting spring. A limiting groove is formed on the storage base. The limiting spring is disposed in the limiting groove. The limiting spring drives the limiting block to protrude out of the limiting groove. The surface of the limiting block near the base is an arc surface.

[0011] By adopting the above technical solution, the limiting spring drives the limiting block to protrude out of the limiting groove. Since the surface of the limiting block near the base is arc-shaped, when the lifting structure drives the lifting plate to rise, the lifting plate can drive the placement tube to abut against the arc surface of the limiting block, allowing the limiting block to move into the limiting groove. This allows the limiting block to not restrict the movement of the placement tube until the placement tube moves to the side of the limiting block away from the base. At this time, the limiting spring drives the limiting block to protrude out of the limiting groove, allowing the limiting block to limit the placement tube and prevent it from falling, so that the placement tube can be stably placed in the storage base.

[0012] Optionally, the base is provided with a striking structure, the striking structure is provided with a striking block, and the striking structure drives the striking block to strike the placement tube.

[0013] By adopting the above technical solution, the tapping structure continuously taps the placement tube with tapping blocks, causing the placement tube to vibrate. This prevents adjacent board-to-board connectors from getting stuck in the placement tube, allowing them to quickly detach from it. Because the tapping frequency of the structure is very low, it will not damage the board-to-board connectors in the placement tube.

[0014] Optionally, the base is provided with a placement seat, the placement seat has a placement hole for stacking placement tubes, the base is provided with a pushing structure, the pushing structure has a pushing plate, the pushing plate has a placement groove for placing placement tubes, and the pushing structure drives the placement tubes to move from one side of the placement seat to the air blowing structure.

[0015] By adopting the above technical solution, the placement tube falls from the placement hole and lands on the push plate. The operator activates the push structure, which moves the push plate to align the placement slot with the placement hole. This allows the placement tube to be moved by the push plate to the air blowing structure, enabling the air blowing structure to move the board-to-board connector in the placement tube so that the air blowing structure can feed the board-to-board connector.

[0016] Optionally, the placement tube is provided with a filler strip, which can seal the opening of the placement tube.

[0017] By adopting the above technical solution, the opening of the placement tube is sealed with a filler strip, making it difficult for the board-to-board connector inside the placement tube to detach from the placement tube during transportation. This allows workers to quickly move the placement tube and reduces the possibility of the board-to-board connector detaching from the placement tube.

[0018] Optionally, the placement hole has two fixing blocks on its wall, and a filling strip passes through between the two fixing blocks. The filling strip has a filling plate on it. A fixing slope is formed on the surface of the fixing block away from the placement tube. The distance between the fixing slope and the placement tube gradually increases along the direction from the fixing block to the base. The fixing slope is located on the falling path of the filling plate.

[0019] By adopting the above technical solution, with the filler strip positioned between two fixed blocks and the filler plate abutting against the fixed inclined surface, as the placement tube falls into the placement hole, the filler plate can slide along the fixed inclined surface, allowing the filler strip to move away from the placement tube and detach from it, so that the board-to-board connector can be removed from the placement tube. At the same time, the operator does not need to remove the filler strip from the placement tube before installing the placement tube in the placement seat, avoiding the possibility of the board-to-board connector detaching from the placement tube, reducing the potential damage to the board-to-board connector during placement, reducing the difficulty of placement for the operator, and speeding up the installation of the placement tube.

[0020] Optionally, a clearance ramp is provided on the surface of the fixing block near another fixing block, the distance between the two clearance ramps gradually increases along the direction from the fixing block to the base, and a filling strip passes between the two clearance ramps.

[0021] By adopting the above technical solution, when the filler strip is located between two fixed blocks, the fixed blocks can restrict the filler strip, allowing the filler strip to move stably in a direction away from the placement tube; as the filler strip passes between two relief ramps, since the distance between the two relief ramps gradually increases along the direction from the fixed block to the base, the filler strip can be separated from the two fixed blocks, so as to realize the feeding of the filler strip between the two fixed blocks.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The board-to-board connectors are blown out of the placement tube by the air blowing structure, realizing the feeding of board-to-board connectors. The air will not cause the board-to-board connectors to vibrate, so that the board-to-board connectors can move smoothly and avoid high-frequency vibration during feeding. At the same time, since the board-to-board connectors are at a fixed angle in the placement tube, there is no need to re-screen the board-to-board connectors, thus making the board-to-board connectors less likely to be damaged during feeding.

[0023] 2. The tapping structure continuously taps the placement tube with tapping blocks, causing the placement tube to vibrate. This prevents adjacent board-to-board connectors from getting stuck in the placement tube, allowing them to quickly detach. Because the tapping frequency of the structure is very low, it will not damage the board-to-board connectors in the placement tube. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] Example 1 This embodiment discloses a loading module for a board-to-board connector testing device. (Refer to...) Figure 1 A feeding module for a board-to-board connector testing device includes a base 1, on which two placement seats 2 are fixedly connected. Placement seats 2 are provided with placement holes 22, which extend in the vertical direction.

[0028] Reference Figure 1 and Figure 2 Multiple placement tubes 3 are placed between two placement seats 2. One end of the placement tube 3 is placed in the placement hole 22 of one placement seat 2, and the other end of the placement tube 3 is placed in the placement hole 22 of the other placement seat 2. The placement seat 2 has a through hole 21 that connects to the placement hole 22, and the through hole 21 allows the placement tube 3 to be removed from the placement seat 2.

[0029] Reference Figure 3 The placement tube 3 houses multiple board-to-board connectors. Both ends of the placement tube 3 are equipped with filler strips 31 made of sponge material. Multiple filler blocks 32 are integrally formed on the outer surface of the filler strip 31, arranged in an array along the length of the filler strip 31. One end of the filler strip 31 is bent into a filler protrusion 33. When one end of the filler strip 31 is inserted into the placement tube 3, the filler block 32 can bend and deform to prevent the filler strip 31 from detaching from the placement tube 3, and the filler protrusion 33 extends out of the placement tube 3 to facilitate insertion and removal by the operator. When the placement tube 3 is placed on the placement seat 2, the operator needs to remove the filler strip 31 from the placement tube 3.

[0030] Reference Figure 2 A pushing structure 11 is provided on the base 1, and the pushing structure 11 includes a pushing cylinder, which is fixedly connected to the base 1. A pushing plate 111 is fixedly connected to the drive shaft of the pushing cylinder, and the pushing cylinder drives the pushing plate 111 to move on the base 1. A placement groove 112 is formed on the surface of the pushing plate 111 away from the base 1. The placement groove 112 extends to the side of the pushing plate 111 away from the pushing cylinder, and the placement groove 112 is only for placing one placement tube 3.

[0031] Reference Figure 1 and Figure 2 The base 1 is provided with an air blowing structure 12, which includes an air blowing component 121 and an air blowing pipe 122. The air blowing component 121 is fixedly connected to the base 1, and the air blowing pipe 122 is fixedly connected to the air blowing component 121. When the push plate 111 moves the placement tube 3 to the air blowing pipe 122, the air blowing component 121 blows air, allowing the board-to-board connectors to disengage from the placement tube 3 in sequence, thus realizing the loading process of the board-to-board connectors. At this time, the push plate 111 abuts against the placement tube 3 closest to the base 1 on the placement seat 2, that is, the push plate 111 restricts the placement tube 3 from falling further.

[0032] Reference Figure 1and Figure 2 Two storage seats 4 are fixedly connected to the base 1. Each storage seat 4 has a storage hole 41 for inserting one end of the placement tube 3. The base 1 also has a mounting hole and a lifting structure 13, which includes a lifting cylinder. A lifting plate 131 is fixedly connected to the drive shaft of the lifting cylinder, passing through the mounting hole. The lifting cylinder pushes the lifting plate 131, causing the placement tube 3 to rise and be positioned within the storage hole 41.

[0033] Reference Figure 4 A limiting groove 42 is formed on the wall of the receiving hole 41, and a limiting structure 43 is provided on the wall of the limiting groove 42. The limiting structure 43 is used to restrict the placement tube 3 from falling from the receiving hole 41. The limiting structure 43 includes a limiting spring 431 and a limiting block 432. One end of the limiting spring 431 is fixedly connected to the bottom wall of the limiting groove 42, and the other end of the limiting spring 431 is disposed on the limiting block 432. The limiting spring 431 drives the limiting block 432 to protrude out of the limiting groove 42, and the limiting block 432 can completely retract into the limiting groove 42. The surface of the limiting block 432 near the base 1 is an arc surface, and the limiting block 432 is located in the lifting path of the placement tube 3.

[0034] Reference Figure 4 When the lifting plate 131 lifts the placement tube 3, the placement tube 3 is squeezed by the arc surface of the limiting block 432, so that the placement tube 3 can be located in the receiving hole 41 on the side of the limiting block 432 away from the base 1. As the lifting plate 131 falls, the limiting spring 431 pushes the limiting block 432 out of the limiting groove 42. At this time, the limiting block 432 abuts against the side of the lifting plate 131, so that the limiting block 432 limits the placement tube 3.

[0035] Reference Figure 2 The base 1 has a receiving groove 14, and the receiving groove 14 has a tapping structure 141. The tapping structure 141 includes a tapping cylinder. A tapping block 142 is fixedly connected to the drive shaft of the tapping cylinder. The tapping cylinder drives the tapping block 142 to continuously tap the placement tube 3 to reduce the situation where two adjacent board-to-board connectors in the placement tube 3 get stuck together.

[0036] The implementation principle of Example 1 is as follows: the cylinder is pushed to move the push plate 111, so that the push plate 111 drives the placement tube 3 to detach from the placement seat 2 from the through hole 21. Then the air blowing component 121 blows the board-to-board connector out of the placement tube 3 through the air blowing pipe 122, thereby realizing the feeding of the board-to-board connector.

[0037] Example 2 Reference Figure 5 and Figure 6The difference between this embodiment and embodiment 1 is that a filling plate 34 is integrally formed on one end of the filling strip 31 outside the placement tube 3. Two fixing blocks 23 are fixedly connected to the wall of the placement hole 22, and the filling strip 31 can pass through between the two fixing blocks 23. The filling plate 34 can be located on the side of the fixing blocks 23 away from the placement tube 3.

[0038] Reference Figure 6 A fixing slope 231 is formed on the surface of the fixing block 23 away from the placement tube 3. The distance between the fixing slope 231 and the placement tube 3 gradually increases along the direction from the fixing block 23 to the base 1, and the fixing slope 231 is located on the falling path of the filling plate 34. When the placement tube 3 is placed on the placement seat 2, the filling strip 31 does not need to be pulled out. At this time, the filling plate 34 moves along the fixing slope 231, so that the filling plate 34 drives the filling strip 31 to gradually move away from the placement tube 3.

[0039] Reference Figure 6 A clearance ramp 232 is formed on the surface of the fixing block 23 near another fixing block 23. The distance between the clearance ramp 232 and the other fixing block 23 gradually increases along the direction from the fixing block 23 to the base 1. The distance between the two clearance ramps 232 allows the filling strip 31 and the filling block 32 to fall. A discharge hole 15 is formed on the base 1, which is connected to the placement hole 22, and the discharge hole 15 allows the filling strip 31 to pass through.

[0040] The implementation principle of Example 2 is as follows: When the placement tube 3 falls, the filling plate 34 slides along the fixed inclined surface 231, allowing the filling strip 31 to move away from the placement tube 3 until the placement tube 3 falls into the placement groove 112. The pushing plate 111 drives the placement tube 3 to move. At this time, the filling strip 31 is restricted by the fixed block 23, allowing the filling strip 31 to separate from the placement tube 3. The filling strip 31 is located between the two relief inclined surfaces 232, allowing the filling strip 31 to fall smoothly into the discharge hole 15 for discharge.
