Description

Technical Field

[0001] The invention belongs to the technical field of chip feeders, in particular to a chip feeder of a circuit board chip mounter. Background Art

[0002] A waffle box is a packaging container used to store, transport and handle wafers or other similar thin materials. A waffle box feeder is an automated device used to provide waffle boxes to a placement machine, which can perform placement operations by taking materials out of the waffle boxes.

[0003] The waffle box feeder is mainly composed of a slide rail mechanism, a slider mechanism, a loading bin, a loading mechanism, a discharge bin and a lifting mechanism. The slide rail mechanism is used to provide a precise moving path for the slider mechanism and assist in positioning, while the slider mechanism is used to receive and fix the waffle boxes. The loading bin, as the starting point of feeding, is a temporary storage area for waffle boxes to be put into production. The discharge bin is responsible for recycling used waffle boxes and forms a closed loop of material flow with the loading bin. The lifting mechanism helps lift the waffle boxes above the slider mechanism into the discharge bin by vertically lifting the waffle boxes. At the same time, the lifting mechanism is used to assist the slider mechanism in receiving the next group of waffle boxes from the loading bin. In the above-mentioned prior art, since the discharge bin is at the end of the guide rail assembly (such as the attached Fig.13 ). When it is necessary to discharge the material, the slider mechanism needs to return to the end of the guide rail mechanism and then discharge the material through the lifting mechanism. The slider mechanism also needs to move in the opposite direction to the bottom of the feeding mechanism, and the lifting mechanism is operated again to push the slider mechanism upward and support the waffle box at the bottom. The feeding mechanism is operated to release the support for the waffle box at the bottom. At this time, the waffle box carrying the material falls onto the slider mechanism, and then the lifting mechanism is reset, and the slider mechanism starts feeding to complete the operation. These steps will make the entire feeding process cumbersome, thereby reducing the feeding efficiency.

[0004] Based on this, a chip feeder for a circuit board placement machine is proposed. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 13 As shown, the present invention provides a chip feeder for a circuit board placement machine, comprising a base 1, a storage rack 5 and a waffle box body 9, wherein a guide rail 11 is fixedly connected to the top of the base 1, a driving screw 12 is arranged on the guide rail 11, a discharge trough 51 and a lowering trough 52 are arranged on the storage rack 5, and further comprising: a slider mechanism 2, which is movably mounted on the guide rail 11 and is transmission-connected with the driving screw 12; a shifting assembly 3, which is arranged on the slider mechanism 2 and is used to adjust the position of the waffle box body 9 on the slider mechanism 2; a lifting assembly 4, which is arranged on the slider mechanism 2 and is used to receive the waffle box body 9 at the lowering trough 52, and the lifting assembly 4 is also used to lift the empty waffle box body 9 on the slider mechanism 2 into the discharge trough 51; a lowering assembly 7, which is symmetrically mounted on the storage rack 5 and is used to transport the waffle box body 9 at the bottom of the lowering trough 52 to the lifting assembly 4;

[0043] The slider mechanism 2 includes a slider assembly 21 and a block 22 disposed on the slider assembly 21, and a placement groove is provided on the top of the block 22;

[0044] The shifting assembly 3 includes a U-shaped block 31 movably mounted on the block 22, and a spring combination rod 32 is movably sleeved at both ends of the U-shaped block 31. Both ends of the spring combination rod 32 are fixedly connected to the block 22, and the tension spring part of the spring combination rod 32 is used to pull the U-shaped block 31. The two ends of the U-shaped block 31 are also elastically connected to elastic blocks 34. The guide rail 11 is symmetrically fixed with spring pieces 35, and both sides of the block 22 are also fixed with elastic inclined blocks 36. The inner side of the U-shaped block 31 is symmetrically fixed with spring pieces 35. The projection of the elastic block 34 in the moving direction overlaps with the top of the block 33 and the elastic inclined block 36, and the projection of the elastic inclined block 36 in the moving direction is misaligned with the top of the block 33

[0045] By adopting the above scheme, the slider assembly 21 is driven by running the driving screw 12 to drive the block 22 to move toward the storage rack 5, so that the elastic block 34 abuts against the stopper 33 during the movement and remains relatively stationary. At this time, the U-shaped block 31 will drive the second spring piece 35 to slide from the right placement groove of the block 22 to the left placement groove. The second spring piece 35 will abut against the edge of the waffle box body 9 during the movement and compress the second spring piece 35. When the block 22 continues to move and drives the elastic inclined block 1 36 to squeeze the elastic block 34, the elastic block 34 will shrink and disengage from the stopper 33. At this time, the spring combination rod The waffle box body 9 is reset under the action of the tension spring 32, and cooperates with the spring piece 2 35 to clamp the edge of the waffle box body 9, thereby driving the waffle box body 9 to move from the left placement groove of the block 22 to the right placement groove. When the slider mechanism 2 slides to the bottom of the storage rack 5, the left and right placement grooves on the block 22 are respectively under the unloading groove 52 and the discharge groove 51. At this time, the jacking component 4 can push the waffle box body 9 in the right placement groove to the discharge groove 51 for storage. At the same time, the unloading component 7 transports the waffle box body 9 at the bottom of the unloading groove 52 to the jacking component 4, and the loading and discharging are carried out simultaneously, thereby improving the feeding efficiency.

[0046] like Figure 5 As shown, the two ends of the U-shaped block 31 are fixedly connected to the rubber ring 311, and the rubber ring 311 is movably sleeved on the outside of the rod body part of the spring combination rod 1 32;

[0047] With the above solution, the rubber ring 311 can provide resistance when the U-shaped block 31 slides outside the spring assembly rod 1 32 , thereby preventing the U-shaped block 31 from causing the waffle box body 9 to rebound quickly.

[0048] like Figure 1-Figure 8As shown, the slider assembly 21 includes a slider 1 211 which is transmission-connected to the driving screw 12, a slider 212 which is movably sleeved on the outside of the screw portion of the driving screw 12, one end of which is fixedly connected to a spring telescopic rod 213 inside the slider assembly 21, and the other end of the spring telescopic rod 213 is fixedly connected to the slider 2 212. A connecting rod 214 is also fixedly connected to the slider 212, and one end of the connecting rod 214 extends into the block 22 and is movably connected to the block 22;

[0049] A stopper 53 is fixedly connected to the bottom of the storage rack 5, and the projection of the block 22 in the moving direction overlaps with the stopper 53;

[0050] The lifting assembly 4 includes a top block 41 and a top block 43 movably connected to the slider 211. The tops of the top block 41 and the inclined groove 42 can extend to the placement groove of the block 22. The top block 41 and the top block 43 are respectively provided with an inclined groove 42 and an inclined groove 44, and the vertical drop of the inclined groove 42 is greater than the vertical drop of the inclined groove 44.

[0051] The connecting rod 214 is fixedly connected with a convex shaft 1 2141 and a convex shaft 2142 which can slide in the inclined groove 1 42 and the inclined groove 2 44 respectively;

[0052] By adopting the above scheme, during the movement of the slider mechanism 2 toward the storage rack 5, after the block 22 is blocked by the blocking rod 53, the slider 212 remains stationary, while the slider 1 211 continues to move and drives the spring telescopic rod 213 to be stretched, and at the same time, the slider 1 211 also drives the connecting rod 214 to move, so that the convex shaft 1 2141 and the convex shaft 2 2142 slide in the inclined groove 1 42 and the inclined groove 2 44 respectively, so that the inclined groove 1 42 moves upward to push the hollow waffle box body 9 in the right side placement groove at the top of the block 22 into the discharge groove 51, and is elastically released. The inclined block 2 511 is fixed, and at the same time, the upward movement of the top block 2 43 will make the top of the top block 2 43 contact with the bottom of the waffle box body 9 in the feeding chute 52 and support it. At this time, the fixing of the bottom waffle box body 9 is released by the feeding assembly 7, and then the reverse operation drives the screw rod 12 to make the slider assembly 21 move in the opposite direction and reset. At this time, the top block 2 43 will drive the waffle box body 9 to slowly descend and enter the placement groove on the left side of the block 22, thereby preventing the waffle box body 9 from falling on the top block 2 43 and causing the material position in the waffle box body 9 to shift.

[0053] like Figure 1 , Figure 2 and Figure 8-Figure 10As shown, an electromagnet 6 is also installed on the material storage rack 5; the material discharge assembly 7 includes a spring combination rod 71 fixedly connected to the material storage rack 5 and located on both sides of the material discharge trough 52, and an iron frame 72 is movably sleeved outside the spring combination rod 71. The iron frame 72 has a tendency to move away from the material storage rack 5 under the action of the spring part on the spring combination rod 71. A telescopic damping rod 73 is fixedly connected to one side of the iron frame 72. In the initial state, the telescopic damping rod 73 is in a retracted state, and a support plate 74 is fixedly connected to the bottom end of the telescopic damping rod 73;

[0054] The side of the waffle box body 9 is provided with a step, and the electromagnet 6 is energized to adsorb the iron frame 72 to drive the telescopic damping rod 73 and the support plate 74 to move, so that one end of the support plate 74 moves to the bottom of the step part of the waffle box body 9 for support;

[0055] The storage rack 5 is also symmetrically and elastically connected with an elastic inclined block 2 511. When the waffle box body 9 moves upward, the step portion thereof can squeeze the elastic inclined block 2 511 to shrink and enter the discharge slot 51.

[0056] By adopting the above scheme, the electromagnet 6 is powered off during operation. At this time, the iron frame 72 is pushed under the action of the elastic force of the spring combination rod 71, driving the telescopic damping rod 73 and the support plate 74 to move. At this time, one end of the support plate 74 will be separated from the support for the step portion of the waffle box body 9, and the telescopic damping rod 73 will also be reset and contracted. Then the electromagnet 6 is energized again, so that the iron frame 72, the telescopic damping rod 73 and the support plate 74 move toward the waffle box body 9 again, and one end of the support plate 74 supports the step portion of the next group of waffle box bodies 9. At this time, the telescopic damping rod 73 will be forced to extend to the initial position due to the gravity of the waffle box body 9, thereby facilitating the next loading operation of the device.

[0057] like Figure 3 , Figure 4 , Figure 6 and 9 As shown in FIG. 11, a baffle 221 is hingedly connected to the middle of the block 22, and a spring 222 for supporting the baffle 221 is fixedly connected to the bottom of the baffle 221. The baffle 221 can be retracted into the block 22 when rotating clockwise, and the baffle 221 can fix the waffle box body 9 in the left placement groove on the block 22 when rotating counterclockwise;

[0058] One end of the guide rail 11 is fixedly connected to an elastic top block 8; when the slider mechanism 2 moves toward the elastic top block 8, the bottom end of the baffle 221 can rotate counterclockwise;

[0059] By adopting the above scheme, when the slider mechanism 2 moves as a whole toward the elastic top block 8, the bottom end of the baffle 221 will be squeezed by the elastic top block 8 and rotate counterclockwise, so that the bottom end of the baffle 221 squeezes the waffle box body 9 in the placement groove on the left side of the top of the block 22, thereby ensuring the stability of the waffle box body 9 when feeding the patch.

[0060] The working principle and use process of the present invention:

[0061] The empty waffle box body 9 is initially in the placement groove on the left side of the block 22. First, the driving screw 12 is operated to drive the slider assembly 21 to drive the block 22 to move toward the storage rack 5. At the same time, the U-shaped block 31 and the elastic block 34 will also move. During the movement of the elastic block 34, it will abut against the stopper 33 to maintain a relatively static state. At this time, the U-shaped block 31 will drive the second spring piece 35 to slide from the right placement groove of the block 22 to the left placement groove. During the movement, the second spring piece 35 will abut against the edge of the waffle box body 9 and compress the second spring piece 35. When the block 22 continues to move and drives the elastic inclined block 1 36 to squeeze the elastic block 34, the elastic block 3 4 contracts and disengages from the blocking block 33. At this time, it is reset under the action of the tension spring on the spring combination rod 1 32, and cooperates with the spring piece 2 35 to clamp the edge of the waffle box body 9, thereby driving the waffle box body 9 to move from the left placement groove of the block 22 to the right placement groove. When the slider mechanism 2 slides to the bottom of the storage rack 5, the left and right placement grooves on the block 22 are respectively under the unloading groove 52 and the discharge groove 51. At this time, the lifting component 4 can push the waffle box body 9 in the right placement groove to the discharge groove 51 for storage. At the same time, the unloading component 7 transports the waffle box body 9 at the bottom of the unloading groove 52 to the lifting component 4, thereby improving the feeding efficiency.

[0062] When the slider mechanism 2 moves toward the storage rack 5, and after the block 22 is blocked by the blocking rod 53, the slider 212 remains stationary, while the slider 1 211 continues to move and drives the spring telescopic rod 213 to be stretched. At the same time, the slider 1 211 also drives the connecting rod 214 to move, so that the convex shaft 1 2141 and the convex shaft 2 2142 slide in the inclined groove 1 42 and the inclined groove 2 44 respectively, so that the inclined groove 1 42 moves upward to push the hollow waffle box body 9 in the right side placement groove at the top of the block 22 into the discharge groove 51, and is elastically inclined by the block 2 511 is fixed, and at the same time, the upward movement of the top block 2 43 makes the top of the top block 2 43 contact with the bottom of the waffle box body 9 in the feeding chute 52 and support it. At this time, the fixing of the bottom waffle box body 9 is released by the feeding assembly 7, and then the driving screw 12 is reversed to make the slider assembly 21 move in the reverse direction and reset. At this time, the top block 2 43 will drive the waffle box body 9 to slowly descend and enter the placement groove on the left side of the block 22, so as to prevent the waffle box body 9 from falling on the top block 2 43 and causing the material position in the waffle box body 9 to shift;

[0063] The electromagnet 6 is powered off during operation. At this time, the iron frame 72 is pushed under the elastic force of the spring combination rod 2 71 to drive the telescopic damping rod 73 and the support plate 74 to move. At this time, one end of the support plate 74 will be separated from the support for the step portion of the waffle box body 9, and the telescopic damping rod 73 will also be reset and contracted. Then, the electromagnet 6 is powered on again, so that the iron frame 72, the telescopic damping rod 73 and the support plate 74 move toward the waffle box body 9 again, and one end of the support plate 74 supports the step portion of the next group of waffle box bodies 9. At this time, the telescopic damping rod 73 will be forced to extend to the initial position due to the gravity of the waffle box body 9, thereby facilitating the next feeding operation of the device.

[0064] When the slider mechanism 2 moves as a whole toward the elastic top block 8, the bottom end of the baffle 221 will be squeezed by the elastic top block 8 and rotate counterclockwise, so that the bottom end of the baffle 221 squeezes the waffle box body 9 in the placement groove on the left side of the top of the block 22, thereby ensuring the stability of the waffle box body 9 when feeding the patch.
