Description

Technical Field

[0001] The present invention relates to the technical field of electronic component conveying, and in particular to a semiconductor component conveying device for a chip mounter. Background Art

[0002] The placement machine, also known as the placement machine or surface mount system, is configured after the dispensing machine or screen printer in the production line. It is a device that accurately places surface mount components on the PCB pads by moving the placement head. It is a device used to achieve high-speed and high-precision placement of components. It is the most critical and complex equipment in the entire SMI production. When the placement machine is placing components, a large number of electronic components need to be transported to assist the placement machine in placement. The existing device needs to eliminate the static electricity generated when transporting the electronic components to prevent it from causing damage to the electronic components, but the existing conveying device is less effective in eliminating static electricity.

[0003] For example, in an electronic component transport vehicle provided by authorization announcement No. CN115352840B, while the conductive roller rotates, the first magnet will continuously pass by one side of the second magnet, so that the second magnet is attracted close to the first magnet, and then the first magnet is deflected away. The second magnet is quickly reset due to the elastic force of the spring, so that the gas at the spring blows toward the wet water cotton, so that the moisture on the surface of the wet water cotton is evaporated, and the air humidity at the lower side of the conveyor belt is increased to reduce the generation of static electricity.

[0004] It has major disadvantages: the rotating rod needs to be rotated to make the second magnet repeatedly slide on the inner wall of the connection point between the evaporation tank and the conductive roller, so as to achieve the effect of blowing, and blow the moist air in the evaporation tank to the conveyor belt. During the blowing process, the blowing direction is directly toward the wet water cotton, and the gas will move to both ends of the length direction of the wet water cotton, causing disturbance of the gas in the evaporation tank, and the humidification effect on the conveyor belt is low; at the same time, the device first moistens the conveyor belt and then cleans it. The moist dust is more sticky and adheres to the conveyor belt, which is inconvenient to clean. Summary of the invention

[0005] The embodiment of the present application provides a semiconductor component conveying device for a chip mounter, which solves the problem in the prior art that a rotating rod needs to be rotated to make the second magnet repeatedly slide on the inner wall of the connection between the evaporation tank and the conductive roller, so as to achieve the effect of blowing, and blow the moist air in the evaporation tank to the conveyor belt. During the blowing process, the blowing direction is directly toward the wet water cotton, and the gas will move to both ends of the length direction of the wet water cotton, causing disturbance of the gas in the evaporation tank, and the humidification effect on the conveyor belt is low; at the same time, the device first moistens the conveyor belt and then cleans it, so the moist dust has a relatively high viscosity. The dust on the surface of the conveyor belt is large and attached to the conveyor belt, which is inconvenient to clean. The scraper is used to scrape the dust on the conveyor belt first, which can avoid contact with the moist air first and causing the dust on the conveyor belt to become moist, inconvenient to clean, and attached to the roller; at the same time, the direction of the sliding groove is changed to make the output end of the sliding groove tilted upward. When the gas in the sliding groove is ejected, the moist air in the moistening groove is directly driven to blow upward. The tilted upward blowing method can make the moist air form a more even distribution on the conveyor belt, improve the moistening effect around the conveyor belt, and avoid turbulence causing the moist air to be transported less efficiently.

[0027] The length of the scraper is consistent with the width of the conveyor belt;

[0028] The swing assembly includes a swing frame and absorbent cotton;

[0029] The swing frame is a rectangular parallelepiped frame, the absorbent cotton is fixed on the inner wall of the swing frame, the swing frame is arranged in the moistening tank, and the lower end of the absorbent cotton of the swing frame extends into the water in the water storage tank.

[0030] As an improvement, the static electricity removal assembly further includes a magnet three and a fixing rod;

[0031] The magnet three is fixed on the upper end of the swing frame, and the magnet three and the magnet two are repelled from each other on the side close to each other;

[0041] The number of the magnets one is consistent with the number of the magnets two, and they correspond one to one. The plurality of magnets one are evenly spaced and distributed along the axis direction of the roller. The magnets one are DC electromagnets.

[0042] As an improvement, the swing assembly further includes an air bag;

[0043] The airbag is fixed to the inner wall of the swing frame, and there are two absorbent cottons, which are located on both sides of the airbag and on both sides of the swing direction of the swing frame;

[0044] The absorbent cotton is a polyurethane sponge;

[0045] The airbag is provided with an inflation port and can be connected to an external inflation device.

[0046] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0047] First, the dust on the surface of the conveyor belt is first scraped off by the scraper, which can avoid contact with the moist air first, which may cause the dust on the conveyor belt to become moist, inconvenient to clean, and adhere to the roller; at the same time, the direction of the sliding groove is changed, so that the output end of the sliding groove is tilted upward, and when the gas in the sliding groove is ejected, the moist air in the moistening groove is directly driven to blow upward. The tilted upward blowing method can make the moist air form a more even distribution on the conveyor belt, improve the moistening effect around the conveyor belt, and avoid turbulence causing the moist air to be transported. The efficiency is reduced;

[0048] Secondly, the left and right swing of the absorbent cotton increases the fluidity and mixing degree of the air, so that the moist air can be more evenly distributed around the conveyor belt, improving the moistening effect; accelerating evaporation, the swinging surface of the absorbent cotton can more effectively contact the air, promote the evaporation of water, thereby increasing the humidity in the air and further reducing the generation of static electricity. At the same time, the swing of the absorbent cotton in the water tank can make the water in the water tank more evenly distributed on the absorbent cotton, avoiding the accumulation of water in some areas and insufficient in other areas, ensuring that the absorbent cotton can continuously and stably provide a moist environment for the conveyor belt; when the swing frame swings left and right, it can hit the inner wall of the moistening tank, so that the water on the absorbent cotton vibrates down and moistens the moistening tank;

[0049] Thirdly, the magnet 1 is an electromagnet, and multiple blowing parts are added, and there are multiple swing components. During use, the blowing times and blowing strength of the corresponding blowing parts can be changed by the magnet 1, and the wetting condition can be increased for the area with larger static electricity, and the wetting condition can be reduced for the area with smaller static electricity, thereby improving the effect of eliminating static electricity on the conveyor belt surface; by accurately controlling the wetting condition of different areas, the wetting resources can be more reasonably allocated, waste can be avoided, and energy utilization efficiency can be improved;

[0050] Fourthly, the squeezed absorbent cotton can increase the wetness of the inner wall of the wetting groove, thereby further increasing the wetness of the air inside the wetting groove, changing the inflation degree of the airbag, and changing the contact area between the absorbent cotton and the inside of the wetting groove, so as to adapt to various working conditions. The deformation of the airbag can make the absorbent cotton contact with the inner wall of the wetting groove in a larger range, which can further increase the wetness of the inside of the wetting groove.

[0068] Embodiment 1: Figure 1-Figure 4 As shown, the present application discloses a semiconductor component conveying device for a chip mounter, comprising a supporting component 100, a static electricity removal component 200, and a swing component 300;

[0069] The support assembly 100 includes a fixed table 110 and a conveyor belt 120;

[0070] The conveyor belt 120 is fixed on the fixed table 110;

[0071] The static electricity removal assembly 200 includes a fixed block 210, a rotating tank 211, a roller 220, a magnet 230 and a wetting tank 213;

[0072] The fixing block 210 is fixed on the fixing table 110 , and the fixing block 210 is located below the conveyor belt 120 ;

[0073] The upper side of the fixing block 210 is provided with a rotation groove 211 and a wetting groove 213;

[0074] The roller 220 is rotatably connected in the rotating groove 211, the axis direction of the roller 220 is perpendicular to the conveying direction of the conveyor belt 120, the rotation axis of the roller 220 is parallel to the ground, and the side of the roller 220 is in close contact with the conveyor belt 120;

[0075] The roller 220 has a magnet 230 therein;

[0076] The swing assembly 300 is disposed in the wetting tank 213;

[0077] The static electricity removal assembly 200 further includes a blowing member, which includes a sliding slot 212, a second magnet 240, a spring 250 and a fixing plate 260;

[0078] The fixed block 210 has a sliding groove 212 in it, and the two ends of the sliding groove 212 are respectively connected to the rotating groove 211 and the wetting groove 213, and the sliding groove 212 is inclined, and the end of the sliding groove 212 close to the wetting groove 213 is higher than the end close to the rotating groove 211;

[0079] The fixing plate 260 is fixed at one end of the sliding groove 212 close to the wetting groove 213, one end of the spring 250 is fixed at one side of the fixing plate 260 away from the wetting groove 213, the second magnet 240 is slidably connected in the sliding groove 212, and the second magnet 240 is fixed at one end of the spring 250 away from the fixing plate 260;

[0080] The inclination angle between the sliding groove 212 and the ground is 10-15 degrees;

[0081] When the conveyor belt 120 conveys the semiconductor components, it drives the roller 220 to rotate together. When the conveyor belt 120 is working, the part after conveying the semiconductor components first reaches the top of the wetting tank 213 and then contacts the roller 220.

[0082] When the roller 220 rotates to the side close to the second magnet 240, the first magnet 230 and the second magnet 240 that are close to each other attract each other;

[0083] The length of the wetting groove 213 is consistent with the width of the conveyor belt 120, and the cross section of the wetting groove 213 is an inverted trapezoid;

[0084] The roller 220 is made of conductive material, and one end of the roller 220 that is rotatably connected is connected to a grounding wire;

[0085] The static electricity removal assembly 200 further includes a water storage tank 214 and a scraper 270;

[0086] The inner bottom side of the moistening tank 213 is provided with a water storage tank 214, and the water storage tank 214 stores water;

[0087] The scraper 270 is fixed to one side of the fixed block 210, and the scraper 270 is located on the side of the moistening tank 213 away from the rotating tank 211, and the upper end of the scraper 270 is close to the conveyor belt 120, and the conveyor belt 120 is used to scrape dust on the surface of the conveyor belt 120;

[0088] The length of the scraper 270 is consistent with the width of the conveyor belt 120;

[0089] The swing assembly 300 includes a swing frame 310 and absorbent cotton 320;

[0090] The swing frame 310 is a rectangular parallelepiped frame, the absorbent cotton 320 is fixed to the inner wall of the swing frame 310, the swing frame 310 is arranged in the moistening tank 213, and the lower end of the absorbent cotton 320 of the swing frame 310 extends into the water in the water storage tank 214;

[0091] The conveyor belt 120 is a prior art and will not be described in detail here.

[0092] When the device is in use, the semiconductor components are transported through the conveyor belt 120. During the transportation process, the scraper 270 can first scrape the dust off the part of the surface of the conveyor belt 120 that contacts the semiconductor components for cleaning. When the conveyor belt 120 rotates, it can drive the roller 220 to rotate together. When the roller 220 rotates, the magnet 1 230 absorbs the magnet 2 240. When the magnet 1 230 in the roller 220 rotates to the other side and is farther and farther away from the magnet 2 240, the magnet 2 240 is reset by the spring 250. During the reset process, the air in the sliding groove 212 is driven to be discharged from the wetting groove 213, and the moist air in the wetting groove 213 is transported to the surface of the conveyor belt 120 to eliminate static electricity. At the same time, one end of the roller 220 that is rotatably connected is grounded. The roller 220 is made of conductive material and can also eliminate static electricity on the surface of the conveyor belt 120.

[0093] Compared with the prior art, when in use, the dust on the surface of the conveyor belt 120 is first scraped off by the scraper 270, which can avoid contact with humid air first, thereby causing the dust on the conveyor belt 120 to become moist, making it inconvenient to clean, and adhering to the roller 220; at the same time, the direction of the sliding groove 212 is changed so that the output end of the sliding groove 212 is tilted upward, and when the gas in the sliding groove 212 is ejected, the humid air in the wetting groove 213 is directly driven to blow upward, and the tilted upward blowing method can make the humid air form a more even distribution on the conveyor belt, thereby improving the wetting effect around the conveyor belt 120 and avoiding turbulence that reduces the conveying efficiency of the humid air.

[0094] Embodiment 2: In embodiment 1, the air in the sliding groove 212 is ejected to transport the moist air in the moistening groove 213 to the surface of the conveyor belt 120 to eliminate static electricity. However, when in use, the moistening efficiency is low. Based on this, the solution of embodiment 1 is improved, such as Figure 5-Figure 7 As shown:

[0095] The static electricity removal assembly 200 further includes a magnet 3 280 and a fixing rod 290;

[0096] The magnet 3 280 is fixed to the upper end of the swing frame 310, and the magnet 3 280 and the magnet 2 240 repel each other on the side close to each other;

[0097] The fixing rod 290 is fixed in the wetting tank 213, the fixing rod 290 is cylindrical, and the axis of the fixing rod 290 is parallel to the rotation axis of the roller 220;

[0098] The swing assembly 300 further includes a fixing ring 330;

[0099] The fixing ring 330 is fixed to one side of the swing frame 310, and the fixing ring 330 is rotatably connected to the fixing rod 290, and the rotation axis of the fixing ring 330 and the axis of the fixing rod 290 are on the same straight line;

[0100] The fixing rod 290 is sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixed on the fixing rod 290 and the fixing ring 330;

[0101] The repulsive force between the magnet 3 280 and the magnet 2 240 is greater than the torsion force of the torsion spring on the fixing rod 290;

[0102] When the swing frame 310 swings, it can hit both sides of the inner wall of the wetting tank 213.

[0103] Magnet 2 240 and magnet 3 280 are always in a repulsive state. When magnet 2 240 is attracted by magnet 1 230 and the position changes, the repulsive force between magnet 2 240 and magnet 3 280 gradually weakens, and the swing frame 310 rotates toward the side close to magnet 2 240 through the torsion spring at the rotating connection of the fixed rod 290; when magnet 2 240 loses the adsorption of magnet 1 230 and resets, the repulsive force between magnet 3 280 and magnet 2 240 increases, causing the swing frame 310 to reset and swing back to its original position.

[0104] The left and right swinging of the absorbent cotton 320 increases the fluidity and mixing of the air, so that the humid air can be more evenly distributed around the conveyor belt 120, thereby improving the wetting effect; accelerating evaporation, the swinging surface of the absorbent cotton 320 can more effectively contact the air, promote the evaporation of water, thereby increasing the humidity in the air and further reducing the generation of static electricity. At the same time, the swinging of the absorbent cotton 320 in the water tank can make the water in the water storage tank 214 more evenly distributed on the absorbent cotton 320, avoiding the accumulation of water in some areas and insufficient water in other areas, thereby ensuring that the absorbent cotton 320 can continuously and stably provide a humid environment for the conveyor belt; when the swing frame 310 swings left and right, it can hit the inner wall of the wetting tank 213, so that the water on the absorbent cotton 320 vibrates down and wets the wetting tank 213.

[0105] Embodiment 3: When the embodiment 2 is in use, the range of air humidity cannot be reasonably distributed. On one side of the conveyor belt 120 where electronic components are frequently transported, more static electricity may be generated on that side; at the same time, on the windward side of the conveyor belt 120, the drying speed will be faster, so more static electricity may be generated on this side. Based on this, the solution of the embodiment 2 is improved, such as Figure 8-Figure 10 As shown:

[0106] There are multiple swing assemblies 300, which are evenly spaced and rotatably connected to the fixed rod 290;

[0107] The number of torsion springs sleeved on the fixing rod 290 is consistent with the number of the swinging components 300, and they correspond one to one;

[0108] The number of the blowing members corresponds to the number of the swinging assemblies 300, and the blowing members are evenly spaced and distributed along the axis direction of the roller 220;

[0109] The number of the magnets 1 230 is consistent with the number of the magnets 2 240 and corresponds one to one. The plurality of magnets 1 230 are evenly spaced and distributed along the axis direction of the roller 220 . The magnets 1 230 are DC electromagnets.

[0110] When one side of the conveyor belt 120 is facing the wind or semiconductor components are frequently transported, resulting in high static electricity, the magnetic force of the corresponding magnet 1 230 can be controlled to increase and the number of opening times can be changed. When the roller 220 rotates, the change in magnetic force and the number of opening times can make it adsorb the magnet 2 240 close to it, and the air can be sprayed from the sliding groove 212 multiple times and with great force into the wetting groove 213.

[0111] Magnet 1 230 is an electromagnet, and multiple blowing parts are added. There are multiple swing components 300. During use, the blowing frequency and blowing strength of the corresponding blowing parts can be changed through magnet 1 230. For areas with larger static electricity, the wetting condition can be increased, and for areas with smaller static electricity, the wetting condition can be reduced, thereby improving the effect of eliminating static electricity on the surface of the conveyor belt 120. By accurately controlling the wetting conditions of different areas, the wetting resources can be more reasonably allocated to avoid waste and improve energy utilization efficiency.

[0112] Embodiment 4: When the embodiment 3 is used, the wetting effect on the surface of the conveyor belt 120 is poor, and the device can be further improved to improve the wetting effect on the surface of the conveyor belt 120. Based on this, the solution of the embodiment 3 is improved, such as Fig.11 As shown:

[0113] The swing assembly 300 also includes an air bag 340;

[0114] The airbag 340 is fixed to the inner wall of the swing frame 310, and there are two absorbent cottons 320, which are located on both sides of the airbag 340 and on both sides of the swing direction of the swing frame 310;

[0115] The absorbent cotton 320 is a polyurethane sponge;

[0116] The airbag 340 has an inflation port and can be connected to an external inflation device.

[0117] The absorbent cotton 320 is a polyurethane sponge, which can adapt to the deformation of the expansion amount of the airbag 340. Before the device is used, the airbag 340 can be connected to an external air source to change its inflation amount. During the swinging process of the swing frame 310, the expanded airbag 340 can make the absorbent cotton 320 on both sides of the airbag 340 collide with the wetting groove 213. The airbag 340 and the wetting groove 213 squeeze the absorbent cotton 320, so that the water in the absorbent cotton 320 adheres to the inner wall of the wetting groove 213. The deformation of the airbag 340 can make the absorbent cotton 320 contact with the inner wall of the wetting groove 213 in a larger range, thereby increasing the contact area.

[0118] The squeezed absorbent cotton 320 can increase the wetness of the inner wall of the wetting groove 213, thereby further increasing the wetness of the air inside the wetting groove 213. The inflation degree of the airbag 340 can be changed, and the contact area between the absorbent cotton 320 and the inside of the wetting groove 213 can be changed to adapt to various working conditions. The deformation of the airbag 340 can make the absorbent cotton 320 contact the inner wall of the wetting groove 213 in a larger range, which can further increase the wetness of the inside of the wetting groove 213.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
