[0027] See also Figure 1, is a structural schematic diagram of a suction pen base 100 provided by an embodiment of the utility model. The suction pen base 100 is used to carry a vacuum suction pen 200. The vacuum suction pen 200 is used to absorb and transfer chips in the chip packaging and testing process. The vacuum suction pen 200 absorbs chips by the principle of internal vacuuming. When the vacuum suction pen 200 does not need to work, it can be placed in the suction pen base 100. On the one hand, it prevents the vacuum suction pen 200 from being thrown away at will and causing losses; on the other hand, it ensures the cleanliness of the vacuum suction pen 200; on the other hand, it can stop vacuuming by cooperating with the suction pen base 100 to reduce waste.
[0028] For the convenience of description, the suction pen base 100 is defined to have a length direction and a width direction that are perpendicular to each other.
[0029] The suction pen base 100 includes a suction pen groove 101 extending in the length direction, an air pipe groove 102 arranged parallel to and spaced from the suction pen groove 101, and a connecting groove 103 connecting the suction pen groove 101 and the air pipe groove 102. The suction pen groove 101 is used to accommodate the vacuum suction pen 200, the air pipe groove 102 is used to accommodate the air pipe 300, and the vacuum suction pen 200 is connected to the air pipe 300 to provide suction for the vacuum suction pen 200.
[0030] Combination Figure 2-3 As shown, the pen suction base 100 includes a first side wall 11 and a second side wall 12 that are arranged opposite to each other, and a bottom wall 13 that connects the first side wall 11 and the second side wall 12. The first side wall 11, the second side wall 12 and the bottom wall 13 are collectively arranged to form a pen suction groove 101. The first side wall 11 is slightly wider than the second side wall 12, and the tracheal groove 102 and the connecting groove 103 are arranged on the first side wall 11. The connecting groove 103 is located between the pen suction groove 101 and the connecting groove 103 along the width direction to achieve the function of connecting the pen suction groove 101 and the tracheal groove 103.
[0031] The pen suction base 100 includes a cover plate 30 covering the pen suction groove 101 and the air pipe groove 103, which is dustproof and waterproof. The upper surface of the cover plate 30 is flush with the upper surface of the first side wall 11, which does not affect the appearance.
[0032] Along the length direction, the connecting groove 103 is narrower than the tracheal groove 102. The suction pen base 100 includes a transition surface 104 formed between the connecting groove 103 and the tracheal groove 102 to limit the following pressing block 20 to prevent it from excessive sliding or even falling off.
[0033] Combination Figure 6-7As shown, the distance between the first side wall 11 and the second side wall 12 is greater than the outer diameter of the vacuum pen 200. The pen base 100 includes a pair of clamping planes 14 provided on the first side wall 11 and the second side wall 12, and the distance between the two opposite clamping planes 14 is equal to the outer diameter of the vacuum pen 200, so as to clamp the vacuum pen 200 on both sides along the width direction. The pen base 100 can be provided with multiple pairs of clamping planes 14 to improve the stability of clamping the vacuum pen 200.
[0034] The suction pen base 100 includes a pressing block 20 at least partially disposed in the connecting groove 102. The pressing block 20 has a first abutting portion 21 for cooperating with the vacuum suction pen 200 and a second abutting portion 22 for cooperating with the air tube 300. The pressing block 20 is slidably disposed along the width direction of the suction pen base relative to the connecting groove 102, so that when the vacuum suction pen 200 is placed in the suction pen groove 101, the first abutting portion 21 is pressed, and the second abutting portion 22 is driven to squeeze the air tube 300.
[0035] The pressing block 20 is located between the vacuum pen 200 and the air tube 300 along the width direction. When the pressing block 20 is slidable along the width direction, it can abut against the vacuum pen 200 or squeeze the air tube 300. In this way, when the vacuum pen 200 is used up and placed in the pen slot 101, the air tube 300 can be blocked at the same time, and the vacuuming of the vacuum pen 200 can be cut off, thereby avoiding waste caused by vacuum leakage.
[0036] The pressing block 20 includes a main body 23 slidably matched with the connecting groove 103 , and the first abutting portion 21 and the second abutting portion 22 are located at two ends of the main body 23 along the width direction to contact the vacuum pen 200 and the air pipe 300 respectively.
[0037] The pressing blocks 20 are symmetrically arranged along the length direction, which is conducive to more stable and smooth sliding.
[0038] The second abutting portion 22 has an arcuate abutting surface 221 for abutting the trachea 300 . The arcuate abutting surface 221 has a good blocking effect and will not cause damage to the trachea 300 .
[0039] The second abutting portion 22 is located in the middle of the main body 23 along the length direction, and is subjected to force at the middle position, which is beneficial to the sliding of the entire abutting block 20 .
[0040] Along the length direction, the chord length of the arcuate contact surface 221 is greater than one-fourth of the length of the tracheal groove 102 and less than one-third of the length of the tracheal groove 102. The arcuate contact surface 221 cannot be too long along the length direction, otherwise the resistance to the insertion of the vacuum suction pen 200 is too great, resulting in the inability to smoothly insert the vacuum suction pen 200 into the suction pen groove 101. The arcuate contact surface 21 cannot be too narrow along the length direction, otherwise it is too sharp for the trachea 300 and easily causes damage, and too narrow will cause the trachea 300 to be too compressed, which is not conducive to the elastic recovery of the trachea 300.
[0041] The first abutting portion 21 has a planar abutting surface 211 for abutting the vacuum suction pen. The planar abutting surface 211 is a vertical surface. When the vacuum suction pen 200 is placed, it is convenient for the vacuum suction pen 200 to enter the suction pen groove 101 along the vertical surface 211. When the vacuum suction pen 200 needs to be taken out, it is also convenient to take it out.
[0042] In other embodiments, the first abutting portion 21 may also have an arcuate surface adapted to the outer contour of the vacuum pen 200, which is equivalent to an arcuate groove. After the vacuum pen 200 is placed, it has a limiting clamping function, but it is not conducive to taking it, and taking it will be relatively inconvenient.
[0043] The pressing block 20 includes a limiting portion 24 located on both sides of the main body 23 along the length direction, and the limiting portion 24 is located on the side of the second abutting portion 22 away from the trachea 300 along the width direction. It is used to limit the sliding of the pressing block 20 along the width direction to prevent the pressing block 20 from transitioning into the pen suction groove 101 or even falling off. The limiting portion 24 has a limiting plane 241 abutting against the transition surface 104 along the width direction.
[0044] Combination Figure 4-5 As shown, the utility model also includes a vacuum suction pen device 1000, including the suction pen base 100, the vacuum suction pen 200 and the air pipe 300, wherein the air pipe 300 passes through the air pipe groove 102 and is connected to the vacuum suction pen 200. The air pipe 300 is also connected to an external air circuit for vacuuming the vacuum suction pen 200.
[0045] Combination Figure 8 As shown, the vacuum pen 200 includes a hollow vacuum hole 201 and a vent hole 202 connecting the vacuum hole 201 and the outside. When the vacuum pen 200 is placed in the pen groove 101 , the clamping plane 14 seals the vent hole 202 .
[0046] In actual operation, the user takes the vacuum pen 200 from the pen slot 101. When the chip needs to be sucked, the user blocks the vent 202 with a finger. In this way, the vacuum pen 200 will not leak, which facilitates the air pipe 300 to draw a vacuum and provides suction force for the vacuum pen 200 to the chip. When the chip needs to be put down, the user releases the finger, the vent 202 leaks, the vacuum pen 200 has no suction force, and the chip falls. After use, the vacuum pen 200 is put down, the clamping plane 14 seals the vent 202, and the pressing block 20 squeezes the air pipe 300 to block the air extraction of the air pipe 300.
[0047] Specifically, the vacuum suction pen 200 includes a pen holder 210, suction heads 230 at both ends of the pen holder 200, and an air pipe joint 220. A gripping portion is provided near the suction head 230 of the pen holder 210, and the vent hole 202 is provided on the gripping portion, which is convenient for fingers to block or release. The gripping portion has planes arranged at intervals along the circumference, which is convenient for gripping. The distance between the first side wall 11 and the second side wall 12 is greater than the outer diameter of the vacuum suction pen 200. More specifically, the suction head 230 can be completely accommodated in the width direction, which can play a role in protecting the suction head 230. The air pipe joint 220 is connected to the air pipe 300, and the air pipe 300 evacuates the vacuum hole 201, and the suction head 230 generates suction force on the chip.
[0048] The vacuum pen 200 has a working state and a resting state. In the working state, the air pipe 300 is normally evacuated, the air pipe 300 returns to its original shape and abuts against the second abutting portion 22, and the pressing block 20 moves toward the pen suction groove 101. Since the pressing block 20 is provided with a limiting portion 24, and the pen suction base 100 also has a transition surface 104 that cooperates with the limiting portion 24, the pressing block 20 will not slide into the pen suction groove 101 to affect the placement of the vacuum pen 200, and will not fall off from the connecting groove 103.
[0049] In the resting state, the vacuum pen 200 abuts the first abutting portion 21 and enters the pen groove 101, the pressing block 20 moves toward the air pipe 300, and the second abutting portion 22 gradually squeezes the air pipe and blocks the air extraction of the air pipe, thereby saving vacuum consumption.
[0050] The beneficial effects of the utility model are as follows: when the vacuum suction pen 200 is inserted, the vacuum suction pen 200 abuts against the first abutting portion 21, and drives the second abutting portion 22 to squeeze the trachea 200, thereby blocking the vacuuming of the trachea and saving dosage; the second abutting portion 22 has an arcuate abutting surface 221, which will not damage the trachea 300, and the chord length of the arcuate abutting surface 221 is greater than one-fourth of the length of the tracheal groove 102 and less than one-third of the length of the tracheal groove 102, which does not affect the insertion of the vacuum suction pen 200, nor does it affect the trachea 300 from restoring its original shape; the limiting portion 24 cooperates with the transition surface 104 to prevent the vacuum suction pen 200 from excessive sliding or even falling off.
[0051] It can be formed by referring to any of the technical solutions provided above, and will not be described in detail here.
[0052] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0053] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
