[0002] The placement machine, also known as the mounting machine, is the main equipment in the SMT production line. It is located after the dispensing machine or screen printer in the production line. Its working principle is to suck up the electronic components through the negative pressure inside the placement head and move the placement head according to the pre-set path, so as to accurately place the resistor components on the PCB pads.
[0003] A Chinese patent with publication number CN104023482B discloses a patch head and a patch machine, including a vertically arranged suction rod and a horizontal rotary motor that drives the suction rod to rotate in the horizontal direction, the horizontal rotary motor includes a motor body and an output shaft, wherein the suction rod is the output shaft of the horizontal rotary motor, and the suction rod can slide relative to the motor body in the vertical direction. The new patch head of the invention has a simple structure, a small mobile unit mass, a fast speed, and high efficiency.
[0004] When the pick and place device of the placement machine in the prior art is in use, since the placement head needs to generate negative pressure to absorb the electronic components, a sliding seal needs to be ensured between the fixed tube and the movable tube. Lubricant is usually applied between the fixed tube and the movable tube to improve the lubrication effect and ensure a sealed environment. However, the movable tube and the fixed tube are usually arranged vertically. During the up and down movement of the movable tube, the lubricant will seep downward, resulting in a gradual reduction in the lubricant between the movable tube and the fixed tube. The lubricant needs to be replenished regularly, and the lubricant replenishment process is relatively cumbersome.
[0005] To this end, the present invention provides a chip pick-up and place device for electronic component chip processing. Summary of the invention
[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.
[0007] The technical solution adopted by the present invention to solve its technical problems is: the present invention is a chip picking and placing device for chip processing of electronic components, comprising a pick and place plate; a lifting plate is provided under the pick and place plate; a group of fixed tubes are evenly fixedly connected inside the pick and place plate; a movable tube is connected inside the fixed tube in a sliding and sealing manner; a patch head is fixedly connected to the lower end of the movable tube, and the patch head is connected to the movable tube; the movable tube passes through the lifting plate and is fixedly connected thereto; a group of storage boxes are evenly fixedly connected to the upper side of the pick and place plate at corresponding positions of the fixed tube, and lubricant is added inside the storage box; the fixed tube passes through the storage box and is fixedly connected thereto; the inner side of the fixed tube is connected to the storage box through an inclined hole; a switch assembly is provided inside the storage box, and the opening and closing of the inclined hole is controlled by the switch assembly; when the pick and place device of the chip placement machine in the prior art is in use, since the patch head needs to generate negative pressure to adsorb the electronic components, a sliding seal needs to be ensured between the fixed tube and the movable tube, and usually there is a gap between the fixed tube and the movable tube. Applying lubricant can not only improve the lubrication effect, but also ensure a sealed environment. However, the movable tube and the fixed tube are usually arranged vertically. During the up and down movement of the movable tube, the lubricant will seep downward, resulting in a gradual reduction in the lubricant between the movable tube and the fixed tube. The lubricant needs to be replenished regularly, and the lubricant replenishment process is relatively cumbersome. At this time, the patch picking and placing device in the present invention is installed inside the patch machine. The existing patch machine is also equipped with a negative pressure component and a lifting component. The top of the fixed tube is connected to the negative pressure component through a pipeline. The lifting component drives the lifting plate and the movable tube to move up and down, thereby realizing the patch work. By setting a storage box, when the lubricant between the fixed tube and the movable tube is gradually reduced, the inclined hole can be controlled to open by the switch component, and then the lubricant inside the storage box automatically flows into the fixed tube and the movable tube through the inclined hole, which plays a role in replenishing the lubricant to ensure a good sealing and lubrication effect between the fixed tube and the movable tube. The operation is convenient and quick.
[0008] Preferably, the switch assembly comprises a straight tube fixedly connected to the inside of the storage box, and the straight tube is aligned with and connected to the inclined hole; a sealing plate is provided on the side of the straight tube away from the inclined hole; an elastic pull rope 1 is fixedly connected between the sealing plate and the inner wall of the straight tube, and the pull rope 1 is in a tensioned state; a connecting rope is fixedly connected to the side of the sealing plate away from the straight tube; one end of the connecting rope away from the sealing plate extends to the outside of the top of the storage box and is fixedly connected to a control block, and the connecting rope passes through the top of the storage box and is slidably connected thereto; under normal circumstances, the pull rope 1 tightens the sealing plate to the side of the straight tube, thereby sealing the straight tube and the inclined hole, and when the fixed tube and the movable tube are closed, the sealing plate is tightened to the side of the straight tube. After the lubricant gradually decreases, the control block can be pulled upwards, and the sealing plate can be pulled by the connecting rope to move in the direction away from the straight tube, so that the sealing plate is separated from the straight tube, allowing the straight tube to be opened. At this time, the lubricant inside the storage box can automatically flow into the space between the fixed tube and the movable tube through the straight tube and the inclined hole, and because the gap between the fixed tube and the movable tube is small, the efficiency of the lubricant automatically flowing into the gap is low. At this time, by loosening the control block, the pull rope pulls the sealing plate toward the straight tube, and the sealing plate pushes the lubricant, thereby pressurizing the lubricant inside the straight tube and improving the efficiency of the lubricant being introduced between the fixed tube and the movable tube.

[0011] Preferably, a pressure ring is slidably connected to the inside of the annular collecting groove above the sponge ring; a group of through holes are evenly opened inside the pressure ring; a mounting hole is opened inside the sponge ring; an elastic member 1 is fixedly connected between the pressure ring and the bottom of the annular collecting groove, and the elastic member 1 passes through the mounting hole; the bottom of the annular collecting groove is connected to the storage box through a flexible conduit; a pressure block is provided at a position near the movable tube on the lower side of the pick-up and place plate; by providing the pressure ring and the through hole, the lubricant can flow downward along the outer wall of the movable tube and penetrate into the sponge ring through the through hole, and when the movable tube moves upward, the pressure block contacts and squeezes the pressure ring, causing the pressure ring to slide downward inside the annular collecting groove, and then the pressure ring squeezes the sponge ring, squeezes the lubricant absorbed inside the sponge ring, and squeezes the lubricant into the conduit, and returns to the storage box through the conduit, which can maintain the continuous water absorption of the sponge ring on the one hand, and can also recycle and reuse the lubricant inside the sponge ring on the other hand, thereby avoiding the waste of lubricant, improving the utilization rate of the lubricant, and saving costs.
[0012] Preferably, a slide groove is provided on the lower side of the pick-and-place plate near the movable tube, and the pressure block is slidably connected inside the slide groove; an electromagnet is fixedly connected to the top of the slide groove; the pressure block is made of magnetic material, and the electromagnet repels the pressure block when energized; an elastic member 2 is fixedly connected between the upper side of the pressure block and the top of the slide groove; under normal circumstances, the pressure block is completely retracted into the slide groove, so that the movable tube will not contact the pressure block during the up and down movement, thereby ensuring the smooth operation of the movable tube, and when a certain amount of lubricant is absorbed inside the sponge ring, the electromagnet can be energized at this time, and then the electromagnet generates a repulsive force on the pressure block and pushes the pressure block downward, and at this time, when the movable tube moves upward, the pressure ring can be squeezed by the pressure block, thereby ensuring that the lubricant inside the sponge ring is squeezed out smoothly.
[0013] Preferably, a flexible spherical block is provided at a position near the catheter inside the storage box; an elastic draw rope 2 is fixedly connected between the spherical block and the inner wall of the catheter, and the draw rope 2 is in a tensioned state; by providing the spherical block and the draw rope 2, under normal circumstances the draw rope 2 will tighten the spherical block on the surface of the catheter and seal the catheter, thereby preventing the lubricant inside the storage box from flowing into the annular collecting groove through the catheter, and when the lubricant inside the sponge ring is squeezed into the catheter, the lubricant pushes the spherical block away under the action of pressure, so that the spherical block is separated from the catheter, and the lubricant can be smoothly introduced into the storage box.
[0014] Preferably, a group of elastic membranes are evenly fixed to the lower side of the pressure ring at the corresponding position of the through hole; the elastic membrane is arranged as an arch structure, and there is a gap between the middle of the elastic membrane and the through hole; due to the gap between the middle of the elastic membrane and the lower side of the through hole, the lubricant can penetrate into the sponge ring through the through hole and the upper side of the elastic membrane, and when the pressure ring slides downward inside the annular collecting groove, the upper side of the sponge ring contacts the elastic membrane and squeezes and deforms the elastic membrane, so that the upper side of the elastic membrane can fit on the surface of the through hole, thereby sealing the through hole, avoiding the problem of the squeezed lubricant overflowing upward through the through hole when the pressure ring squeezes the sponge ring, so that the lubricant can be fully squeezed into the conduit, thereby improving the recovery efficiency of the lubricant.

The device for picking and placing electronic component patches for processing described in the present invention provides a storage box. When the lubricant between the fixed tube and the movable tube is gradually reduced, the inclined hole can be controlled to open by a switch assembly, and then the lubricant inside the storage box automatically flows through the inclined hole between the fixed tube and the movable tube, thereby playing a role in supplementing the lubricant to ensure a good sealing and lubrication effect between the fixed tube and the movable tube, and the operation is convenient and quick.
[0016] 2. The present invention describes a patch picking and placing device for electronic component patch processing. Under normal circumstances, a pull rope is used to tighten the sealing plate to the side of the straight tube, thereby sealing the straight tube and the inclined hole. When the lubricant between the fixed tube and the movable tube gradually decreases, the control block can be pulled upward, and the sealing plate can be pulled by the connecting rope to move in a direction away from the straight tube, and then the sealing plate is separated from the straight tube, so that the straight tube can be opened. At this time, the lubricant inside the storage box can automatically flow into the space between the fixed tube and the movable tube through the straight tube and the inclined hole. After that, by loosening the control block, the pull rope pulls the sealing plate toward the straight tube, and then the sealing plate pushes the lubricant, thereby pressurizing the lubricant inside the straight tube, thereby improving the efficiency of introducing the lubricant between the fixed tube and the movable tube.

However, the movable tube 4 and the fixed tube 3 are usually arranged vertically. During the up and down movement of the movable tube 4, the lubricant will seep downward, resulting in a gradual reduction in the lubricant between the movable tube 4 and the fixed tube 3. The lubricant needs to be replenished regularly, and the lubricant replenishment process is relatively cumbersome. At this time, the patch picking and placing device in the present invention is installed inside the patch machine. The existing patch machine is also equipped with a negative pressure component and a lifting component. The top of the fixed tube 3 is connected to the negative pressure component through a pipeline. The lifting component drives the lifting plate 2 and the movable tube 4 to move up and down, thereby realizing the patch work. In addition, by setting a storage box 6, when the lubricant between the fixed tube 3 and the movable tube 4 is gradually reduced, the inclined hole 7 can be controlled to open by the switch component, and then the lubricant inside the storage box 6 automatically flows into the fixed tube 3 and the movable tube 4 through the inclined hole 7, which plays a role in replenishing the lubricant to ensure a good sealing and lubrication effect between the fixed tube 3 and the movable tube 4, and the operation is convenient and quick.

After the lubricant in the space is gradually reduced, the control block 12 can be pulled upwards, and the sealing plate 9 can be pulled by the connecting rope 11 to move in the direction away from the straight tube 8, so that the sealing plate 9 is separated from the straight tube 8, so that the straight tube 8 can be opened. At this time, the lubricant inside the storage box 6 can automatically flow into the space between the fixed tube 3 and the movable tube 4 through the straight tube 8 and the inclined hole 7, and because the gap between the fixed tube 3 and the movable tube 4 is small, the efficiency of the lubricant automatically flowing into the gap is low. At this time, by loosening the control block 12, the rope 10 pulls the sealing plate 9 toward the straight tube 8, and then the sealing plate 9 pushes the lubricant, thereby pressurizing the lubricant inside the straight tube 8, thereby improving the efficiency of the lubricant introduced into the space between the fixed tube 3 and the movable tube 4.

By setting the sponge ring 17, after the lubricant enters the annular collecting groove 16, the sponge ring 17 can absorb and fix the lubricant, avoiding the problem of the lubricant in the annular collecting groove 16 spilling out during the up and down movement of the movable tube 4.
[0024] A pressure ring 18 is slidably connected inside the annular collecting groove 16 above the sponge ring 17; a group of through holes 19 are evenly opened inside the pressure ring 18; a mounting hole 20 is opened inside the sponge ring 17; an elastic member 21 is fixedly connected between the pressure ring 18 and the bottom of the annular collecting groove 16, and the elastic member 21 passes through the mounting hole 20; the bottom of the annular collecting groove 16 is connected to the storage box 6 through a flexible conduit 22; a pressure block 23 is provided at the lower side of the pick-up and place plate 1 near the movable tube 4; by providing the pressure ring 18 and the through holes 19, the lubricant can flow downward along the outer wall of the movable tube 4 and The lubricant penetrates into the sponge ring 17 through the through hole 19. When the movable tube 4 moves upward, the pressing block 23 contacts and squeezes the pressing ring 18, causing the pressing ring 18 to slide downward inside the annular collecting groove 16. Then, the pressing ring 18 squeezes the sponge ring 17, squeezes out the lubricant absorbed inside the sponge ring 17, and squeezes the lubricant into the conduit 22, and flows back to the storage box 6 through the conduit 22. On the one hand, the continuous water absorption of the sponge ring 17 can be maintained, and on the other hand, the lubricant inside the sponge ring 17 can be recycled and reused, thereby avoiding the waste of lubricant, improving the utilization rate of the lubricant, and saving costs.

When the lubricant inside the sponge ring 17 is squeezed into the conduit 22, the lubricant pushes the spherical block 27 away under the action of pressure, so that the spherical block 27 is separated from the conduit 22, and the lubricant can be smoothly introduced into the storage box 6.
[0027] Embodiment 2 like Figure 6 to Figure 7 As shown, compared with Example 1, another embodiment of the present invention is: a group of elastic membranes 29 are evenly fixed to the lower side of the pressure ring 18 at the corresponding position of the through hole 19; the elastic membrane 29 is set to an arch structure, and there is a gap between the middle of the elastic membrane 29 and the through hole 19; due to the gap between the middle of the elastic membrane 29 and the lower side of the through hole 19, the lubricant can penetrate into the sponge ring 17 through the through hole 19 and the upper side of the elastic membrane 29, and when the pressure ring 18 slides downward in the annular collecting groove 16, the upper side of the sponge ring 17 contacts the elastic membrane 29 and squeezes and deforms the elastic membrane 29, so that the upper side of the elastic membrane 29 can fit on the surface of the through hole 19, thereby blocking the through hole 19, avoiding the problem of the squeezed lubricant overflowing upward through the through hole 19 when the pressure ring 18 squeezes the sponge ring 17, so that the lubricant can be fully squeezed into the conduit 22, thereby improving the recovery efficiency of the lubricant.
[0028] Working principle: The patch pick-up and place device in the present invention is installed inside the patch machine. The existing patch machine is also equipped with a negative pressure component and a lifting component. The top of the fixed tube 3 is connected to the negative pressure component through a pipeline. The lifting component drives the lifting plate 2 and the movable tube 4 to move up and down, thereby realizing the patch work. In addition, by setting a storage box 6, when the lubricant between the fixed tube 3 and the movable tube 4 is gradually reduced, the inclined hole 7 can be controlled to open by the switch component, and then the lubricant in the storage box 6 automatically flows into the space between the fixed tube 3 and the movable tube 4 through the inclined hole 7, which plays a role in supplementing the lubricant to ensure that the fixed tube 3 The sealing and lubricating effect between the fixed tube 3 and the movable tube 4 is good, and the operation is convenient and fast. Under normal circumstances, the pull rope 10 tightens the sealing plate 9 to the side of the straight tube 8, thereby sealing the straight tube 8 and the inclined hole 7.

At this time, the lubricant inside the storage box 6 can automatically flow into the space between the fixed tube 3 and the movable tube 4 through the straight tube 8 and the inclined hole 7, and because the lubricant between the fixed tube 3 and the movable tube 4 is The gap between the two is small, and the efficiency of the lubricant automatically flowing into the gap is low. At this time, by loosening the control block 12, the pull rope 10 pulls the sealing plate 9 toward the straight tube 8, and then the sealing plate 9 pushes the lubricant, thereby pressurizing the lubricant inside the straight tube 8, and improving the efficiency of the lubricant introduced between the fixed tube 3 and the movable tube 4; by setting the flexible pad 13, when the sealing plate 9 is attached to the side of the straight tube 8, the flexible pad 13 can improve the sealing effect of the straight tube 8, ensure the stability of the switch assembly, and avoid the problem of the lubricant inside the storage box 6 leaking through the straight tube 8 to the fixed tube 3 under normal circumstances. By setting the addition The port 14 is used to add lubricant to the storage box 6 when the lubricant in the storage box 6 is exhausted. The retaining ring 15 is provided. When the lubricant between the fixed tube 3 and the movable tube 4 seeps downward, the lubricant will flow into the annular collecting groove 16 along the outer wall of the movable tube 4, thereby preventing the lubricant from flowing to other positions of the placement machine and causing pollution. The sponge ring 17 is provided. After the lubricant enters the annular collecting groove 16, the sponge ring 17 can absorb and fix the lubricant, thereby preventing the lubricant in the annular collecting groove 16 from spilling out during the up and down movement of the movable tube 4.By providing the pressing ring 18 and the through hole 19, the lubricant can flow downward along the outer wall of the movable tube 4 and penetrate into the sponge ring 17 through the through hole 19. When the movable tube 4 moves upward, the pressing block 23 contacts and squeezes the pressing ring 18, causing the pressing ring 18 to slide downward inside the annular collecting groove 16, and then the pressing ring 18 squeezes the sponge ring 17, squeezes the lubricant absorbed inside the sponge ring 17, and squeezes the lubricant into the conduit 22, and flows back to the storage box 6 through the conduit 22. On the one hand, the continuous water absorption of the sponge ring 17 can be maintained, and on the other hand, the sponge ring 17 can be The internal lubricant is recycled and reused, thereby avoiding the problem of lubricant waste, improving the utilization rate of lubricant and saving costs; under normal circumstances, the pressing block 23 is completely retracted into the slide groove 24, so that the movable tube 4 will not contact the pressing block 23 during the up and down movement, ensuring the smooth operation of the movable tube 4, and when a certain amount of lubricant is absorbed inside the sponge ring 17, the electromagnet 25 can be energized at this time, and then the electromagnet 25 generates a repulsive force on the pressing block 23 and pushes the pressing block 23 downward. At this time, when the movable tube 4 moves upward, the pressing ring 18 can be squeezed by the pressing block 23, thereby The lubricant inside the sponge ring 17 is ensured to be squeezed out smoothly; by setting the spherical block 27 and the second pull rope 28, under normal circumstances, the second pull rope 28 pulls the spherical block 27 tight on the surface of the conduit 22 and seals the conduit 22, thereby preventing the lubricant inside the storage box 6 from flowing into the annular collecting groove 16 through the conduit 22. When the lubricant inside the sponge ring 17 is squeezed into the conduit 22, the lubricant pushes the spherical block 27 away under the action of pressure, so that the spherical block 27 is separated from the conduit 22, and the lubricant can be smoothly introduced into the storage box 6; due to the middle part of the elastic membrane 29 and the through hole There is a gap between the lower side of the sponge ring 17 and the lower side of the elastic film 29, so the lubricant can penetrate into the sponge ring 17 through the through hole 19 and the upper side of the elastic film 29, and when the pressure ring 18 slides downward inside the annular collecting groove 16, the upper side of the sponge ring 17 contacts the elastic film 29 and squeezes and deforms the elastic film 29, so that the upper side of the elastic film 29 can fit on the surface of the through hole 19, thereby blocking the through hole 19, avoiding the problem of the squeezed lubricant overflowing upward through the through hole 19 when the pressure ring 18 squeezes the sponge ring 17, so that the lubricant can be fully squeezed into the conduit 22, improving the recovery efficiency of the lubricant. ;
