Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of automatic reading equipment for electronic components, and particularly relates to a placement and positioning platform for DCB reading. BACKGROUND

[0002] In the manufacturing process of power electronic modules (such as IGBT modules), DCB (Direct Copper Bonding) substrates are widely used in high-voltage and high-current device packaging as a composite substrate with both structure and function. The DCB substrate is directly combined by ceramic (such as Al2O3 or AlN) and copper layer, and has excellent thermal conductivity and electrical insulation. In the production process, in order to ensure the electrical stability and manufacturing consistency of the finished module, batch reading or detection of the DCB substrate is required to collect its code, position information or perform function verification.

[0003] At present, when reading or identifying the DCB substrate, a plurality of DCB substrates are usually arranged in a tray, and then identified one by one by a reading device. In order to ensure the stability and positioning accuracy of the DCB substrate during reading, the placement platform of the tray needs to have good positioning, limiting and stabilizing functions. However, the existing placement platform structures generally have the following problems: On the one hand, the placement and disassembly of the tray depend on manual handling or rely on simple support structures. During tray loading or unloading, the tray often shakes or is misaligned during lifting movement due to the lack of limiting structure or untimely release, which affects the stability and positioning accuracy of the DCB board. Although some devices use air cylinder driven mode to realize lifting, they fail to realize coordinated limiting and guiding during loading and unloading, especially when the tray just contacts or separates from the support part, which is prone to rubbing, jamming and other problems.

[0004] On the other hand, during the process of lifting the DCB board with the tray to the reading station, the tray itself is light in weight and is easily affected by external vibration or air cylinder return fluctuation during lifting, resulting in slight displacement or even tilting of the tray. Such small deviations will have a serious impact on high-precision reading. Some existing platforms lack effective adsorption or negative pressure auxiliary mechanisms, and cannot form stable adhesion to the tray during lifting, thus failing to meet the needs of high-precision reading.

[0005] In summary, the existing DCB reading placement platform still has deficiencies in tray positioning stability, limiting release coordination control and adsorption stability during lifting. SUMMARY

[0030] Referring toFigures 1-4 A hollow groove 131 is formed in the center of the surface of the vertical plate 13 for the movement space of the swing rod 31, and the hollow groove 131 penetrates the thickness of the vertical plate 13, which is beneficial to the extension of the swing rod 31 and linkage with the external structure; the top compression mechanism 3 includes a swing rod 31 rotatably installed on the inner side of the vertical plate 13, and the swing rod 31 is connected to the vertical plate 13 through a rotating shaft, so as to realize a certain angle of swing action; the swing rod 31 penetrates the hollow groove 131 and is lapped with the connecting rod 33 to form a linkage structure; the upper surface of the connecting plate 22 is symmetrically provided with an L-shaped extrusion rod 221 on both sides, and the L-shaped extrusion rod 221 is a rigid member with one end horizontal and the other end vertical, the upper end of the L-shaped extrusion rod 221 is fixedly connected to the connecting plate 22, and the lower end is provided with a roller 27 through a hinged manner; the end of the L-shaped extrusion rod 221 extends to the inner side of the hollow groove 131, and the roller 27 is in contact with the upper surface of the swing rod 31; when the connecting plate 22 moves downward with the cylinder 21, the roller 27 extrudes the swing rod 31 downward, so as to realize the release action of the top limiting structure.

[0031] Referring to Figures 4-5 The top compression mechanism 3 further includes a slide rod 32 horizontally sliding on the top of the column 12, the slide rod 32 is in a cylindrical shape, a limiting groove is arranged on the sliding end and the sliding distance is controlled by a limiting block; a telescopic head 34 is arranged on the inner side of the slide rod 32, and the telescopic head 34 is installed on the end of the slide rod 32 through a threaded connection manner; the telescopic head 34 is arranged above the tray 5, a pressing bolt 35 is arranged on the lower surface end of the telescopic head 34, the pressing bolt 35 is in a rectangular block structure, after the tray 5 rises to the highest position, the pressing bolt 35 presses downward on the upper surface edge of the tray 5, so as to realize the downward pressing function, and prevent the tray from jumping during reading.

[0033] Embodiment 2: Referring to Figures 1-3 The components include a cylinder 21, a connecting plate 22, a fixed column 23 and a lifting plate 24.

[0034] In this embodiment, the lifting mechanism 2 adopts a double-acting cylinder 21 of SMC model CDQ2A50-100DC, which is installed at the bottom of the top plate 14. The output end of the cylinder 21 is connected to four stainless steel guide fixed columns 23 with a diameter of 16 mm through an aluminum alloy connecting plate 22 (thickness 10 mm). The fixed columns 23 penetrate through the top plate 14 and slide vertically, and the top is connected to a 304 stainless steel lifting plate 24 with a thickness of 12 mm. When the cylinder 21 is vented downward, it drives the connecting plate 22 and the fixed columns 23 to move downward, realizing the vertical descent of the lifting plate 24. This structure ensures stable guidance during lifting, avoiding oblique deviation or shaking, laying a foundation for subsequent positioning.

[0035] Traditional platforms mostly adopt the form of single-cylinder direct connection to the lifting plate, without setting guide columns for support. When the lifting plate is eccentrically loaded or the air pressure is unstable, it is easy to tilt, which seriously affects the positioning accuracy and equipment stability.

[0036] Embodiment 3: Referring to Figures 1-4 and Figures 6-8 , the components involved include the lifting plate 24, the positioning peg 241, the tray 5, and the positioning hole 52.

[0037] In this embodiment, five stainless steel positioning pegs 241 with a diameter of Φ10 mm are evenly installed on the lifting plate 24, four of which are arranged at the four corners and one is located at the center. The tray 5 is an aluminum mold forming structure, and a Φ10.2 mm circular hole is opened on the lower surface of the tray 5 as the positioning hole 52, with a cooperation gap controlled within 0.2 mm. After the tray is placed, the positioning peg 241 is inserted through the positioning hole 52 to achieve precise positioning, preventing improper placement or horizontal deviation, and ensuring the uniform state of the DCB plate before reading.

[0038] Some factories use magnets or sliding grooves to position the tray. This method relies on the operator's habits for accuracy and has poor repeatability, making it difficult to meet the requirements of large-scale automatic reading equipment.

[0039] Embodiment 4: Referring to Figures 5-8 , the components involved include the support block 26, the inner cavity 261, the rubber gasket 53, the rubber piston 43, and the connecting peg 42.

[0040] The support block 26 in this embodiment is made of POM engineering plastic by injection molding, and has an inner cavity 261 with a diameter of Φ30 mm and a height of 20 mm. The rubber gasket 53 is 2 mm thick and is made of silica gel material and is attached to the upper opening of the support block 26. The rubber piston 43 is fixed to the top of the connecting bolt 42 and is made of NBR material with a diameter of 29 mm and is embedded in the inner cavity 261. When lifting, the piston 43 is pulled away from the inner cavity upward, and after the inner cavity is sealed, a transient negative pressure is formed to adsorb the rubber gasket 53 and then the tray 5, so that the tray 5 is stably attached to the lifting plate 24. This structure prevents the tray from loosening due to micro-vibration during movement.

[0041] Existing equipment relies on springs or friction to fix the tray, and does not form a sealed structure, which is prone to slight displacement during movement, seriously affecting high-precision reading tasks.

[0042] Embodiment 5: Referring to Figures 1-4 and Figures 4-5 , the components include L-shaped extrusion rods 221, rollers 27, swing rods 31, connecting rods 33, sliding rods 32, telescopic heads 34, and pressing bolts 35.

[0043] In this embodiment, L-shaped extrusion rods 221 are arranged on both sides of the connecting plate 22, which are made of carbon steel and have the polyurethane rollers 27 with a diameter of Φ12 mm connected at the ends. When the connecting plate 22 is lowered, the rollers 27 press the swing rods 31 inside the vertical plate 13, the end of the swing rod 31 is connected to the connecting rod 33, which in turn pushes the sliding rod 32 to slide horizontally. The sliding rod 32 has a tapered telescopic head 34 at one end and a nylon pressing bolt 35 below. After the lifting action is completed, the pressure of the roller 27 on the swing rod 31 is released, and the sliding rod 32 is reset to the center under the action of the second spring 36, and the pressing bolt 35 exerts a vertical downward clamping force on the edge of the upper surface of the tray 5, achieving limiting fixation.

[0044] Some traditional equipment does not have any limiting structure after the tray is lifted to the highest position, relying only on its own weight to maintain the position, which is prone to floating or jumping of the tray due to equipment vibration, causing reading distortion.

[0045] Embodiment 6: Referring to Figures 4-5 , the components include sliding rods 32, connecting rods 33, swing rods 31, and second springs 36.

[0046] In this embodiment, the two sliding rods 32 are made of aluminum alloy and are installed above the two vertical columns 12, and are connected by the connecting rod 33 to realize synchronous linkage; the connecting rod 33 is lapped with the swing rod 31 in the middle to ensure that the two sliding rods act simultaneously when extruding or releasing; the second spring 36 is a custom compression spring with a spring force of about 5 N and is arranged between the sliding rod 32 and the vertical column 12. The above structure ensures that the limiting pressing bolt 35 is positioned in place in advance before the tray is lifted to the target position, and the action is symmetrical and synchronous, avoiding eccentric force.

[0047] The general platform adopts a split compression structure, and the left and right sides need to be adjusted independently, so that human error exists, the material tray is unevenly stressed, and inclination clamping or positioning error is caused.

[0048] The working principle of the present application is as follows: in the initial state, the connecting plate 22 is pushed downward by the air cylinder 21, the fixed column 23 can only slide vertically to ensure the stability of the movement of the connecting plate 22, the lifting plate 24 is lowered to the lowermost position of the stroke when the air cylinder 21 is lowered, and the first spring 25 is extruded to store energy, the L-shaped extrusion rod 221 is lowered when the connecting plate 22 is lowered, the roller 27 extrudes the swing rod 31, the end of the swing rod 31 rotates downward, the swing rod 31 extrudes the connecting rod 33, the slide rod 32 is horizontally through the top of the column 12, so that the two slide rods 32 move outward when the connecting rod 33 is extruded outward, so that the telescopic head 34 is closer to the column 12, the distance between the two telescopic heads 34 increases, so that the top of the lifting plate 24 is obstacle-free, so as to facilitate the installation and placement of the material tray 5, and the second spring 36 is also extruded to store energy in the process; When the lifting plate 24 is lowered, the rubber piston 43 is placed inside the inner cavity 261 above due to the fact that the mounting plate 41 is always fixed, then the material tray 5 is placed on the surface of the lifting plate 24, and is positioned through the cooperation of the positioning hole 52 and the positioning pin 241, at this time the rubber gasket 53 covers the top of the supporting block 26 to support the supporting block 26 and seal the top of the inner cavity 261, a plurality of DCB plates are placed in the material groove 51 in advance, so that the plurality of DCB plates in the material tray 5 are effectively positioned after the material tray 5 is positioned, after installation, the air cylinder 21 controls the connecting plate 22 to move upward, and the lifting plate 24 and the material tray 5 move upward synchronously by using the energy stored in the first spring 25, the rubber piston 43 moves downward in the inner cavity 261 during the upward movement, and the top of the inner cavity 261 is sealed by the rubber gasket 53, so that a negative pressure is formed in the inner cavity 261 during the downward movement of the rubber piston 43, so as to adsorb the rubber gasket 53, so that the material tray 5 is always attached to the lifting plate 24 during the upward movement of the material tray 5, thereby preventing the material tray 5 from being dislocated and loose due to vibration of the air cylinder or each component during movement, and improving the positioning accuracy; The L-shaped extrusion rod 221 moves upward when the connecting plate 22 moves upward, and the swing rod 31 is no longer extruded, the telescopic head 34 is ejected to the center position by using the energy stored in the second spring 36, and the pressure pin 35 can move to the upper side of the material tray 5 to limit the highest position of the material tray 5, it should be noted that the pressure pin 35 needs to be moved to the position in advance before the material tray 5 moves to the highest position, this structure moves the pressure pin 35 outward when the material tray 5 is placed below, so as to facilitate the loading and unloading of the material tray 5, and vice versa, the pressure pin 35 moves inward to limit the material tray 5 when the material tray 5 moves upward.

[0049] The above description is only the preferred embodiment of the present application, it should be pointed out that for the ordinary skilled in the art, without departing from the principles of the present application, can also make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
