Description

TECHNICAL FIELD

[0001] The application relates to a copper substrate feeding device and particularly relates to a multi-layer thermoelectric separation copper substrate production and processing feeding device. BACKGROUND

[0002] The multi-layer thermoelectric separation copper substrate is mainly composed of a copper conductive layer, an insulating dielectric layer and a metal heat dissipation layer, and the multi-layer structure makes the copper substrate have excellent electrical conductivity and heat dissipation performance. In the automatic production process of electronic components, the feeding link of the multi-layer thermoelectric separation copper substrate adopts a standardized operation mode. During production, dozens of multi-layer thermoelectric separation copper substrates are neatly stacked on an anti-static feeding table, and then a suction cup mechanical arm equipped with a vacuum negative pressure system will suck and transfer the substrates to the subsequent processing station one by one according to the set process. This feeding mode greatly improves the production efficiency and can meet the needs of large-scale industrial production.

[0003] However, in the production and manufacturing process of the multi-layer thermoelectric separation copper substrate, some problems affecting the subsequent processing will inevitably occur. In the pressing process, in order to enhance the bonding force between the layers, an adhesive containing an oily additive is used, and these oily substances will remain on the surface of the substrate; in the electroplating link, a layer of anti-oxidation oil film will also be applied to the surface of the substrate to prevent copper oxidation. As the production process advances, these process residues will gradually form a thin oil film on the surface of the substrate. When a plurality of substrates with oil film are stacked and stored for a period of time, the adhesive components in the oil film will cause the substrates to stick together. This situation brings some problems to the subsequent production, such as: when the suction cup mechanical arm absorbs a single substrate, it is often difficult to accurately separate the adhered substrates, often causing two substrates to be absorbed at the same time, resulting in feeding failure and affecting the continuity of production; moreover, the existence of the oil film changes the physical properties of the substrate surface, reduces the adsorption force between the suction cup and the substrate, and makes the adsorption feeding unstable, which is prone to problems such as substrate falling; in the welding process, the oil film will decompose and produce carbides at high temperatures, and these carbides will adhere to the surface of the solder pad, forming an isolation layer and hindering the good combination of the solder and the substrate, thereby affecting the welding quality, causing defects such as virtual welding and delamination, and ultimately affecting the overall performance and reliability of the electronic product. SUMMARY

[0004] The purpose of the present application is to provide a multi-layer thermoelectric separation copper substrate production and processing feeding device to solve the above-mentioned background technology. The existing feeding device forms an oil film on the surface of the multi-layer thermoelectric separation copper substrate during single block feeding due to the effects of pressing, electroplating and other processing procedures. These oil films will cause the copper substrates to adhere to each other after stacking. This situation will cause many problems: on the one hand, the subsequent suction cups are easy to adsorb two blocks at the same time when adsorbing single copper substrate, thereby causing feeding failure; on the other hand, the oil film on the surface of the copper substrate not only affects the adsorption and feeding effect of the suction cup mechanical arm, but also has adverse effects on the welding quality and other processing effects during subsequent welding processing.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0033] Embodiment one: please refer to Figure 1 - Figure 9The utility model provides a kind of multi-layer thermoelectric separation copper substrate production processing feeding device, including feeding table 1, support frame 2 fixed in the top of feeding table 1 and storage table 3 fixed in the top of support frame 2, the top one side of storage table 3 is fixedly installed with conveyor 4, the top one side of conveyor 4 is fixedly installed with suction cup mechanical arm 5, the bottom inside of storage table 3 is provided with placing seat 6, two split components are arranged in the both sides of storage table 3, the inside of one side of storage table 3 close to each split component is longitudinally provided with limiting slot 9, and the outside of one side of storage table 3 between two split components is provided with wiping component;Split component includes several limiting blocks 10, several hollow shafts 13 and abutting plate 19, several limiting blocks 10 are slidably engaged and installed in the inside of limiting slot 9, several hollow shafts 13 are fixedly installed on the outside of one side limiting block 10 of corresponding side, and abutting plate 19 is longitudinally arranged on the outside of one side of storage table 3 close to several hollow shafts 13.

[0034] The top corner of placing seat 6 is longitudinally fixedly installed with guide frame 8, the guide frame 8 is L-shaped, the bottom of support frame 2 is fixedly installed with jacking cylinder 7, and the output end of jacking cylinder 7 is fixedly installed with the middle position of the bottom of placing seat 6.

[0035] Specifically, the L-shaped guide frame 8 at the top corner of the placing seat 6 is arranged, so that the side of the copper substrate can be limited and guided by the guide frame 8 during placement, ensuring the stability of the overall placement. At the same time, during subsequent feeding, the copper substrate at the top can be lifted orderly by the intermittent lifting of the jacking cylinder 7, so that the suction cup mechanical arm 5 can adsorb and take the material. After the copper substrate is sucked by the suction cup mechanical arm 5, it is transported, so that the sucked copper substrate is placed on the existing conveyor 4. Then, the copper substrate is conveyed to the next processing and welding post by the conveyor 4, and the overall feeding is smooth and stable.

[0036] The outside of several hollow shafts 13 is rotatably installed with X-shaped connecting rod 11, and the X-shaped connecting rod 11 is rotatably connected with the X-shaped connecting rod 11. Two positioning pull rods 12 are symmetrically rotatably installed on the outside of the middle position close to the bottom of the limiting slot 9 of the storage table 3, and the top of the two positioning pull rods 12 is rotatably connected with the bottom side of the X-shaped connecting rod 11 of the corresponding side.

[0037] The hollow shaft 13 outside close to the two positioning pull rods 12 is fixedly installed with a limiting seat 16, and the side outside close to the bottom of the limiting seat 16 of the support frame 2 is fixedly installed with a cylinder one 14. The top of the cylinder one 14 is fixedly installed with an abutting rod 15, and the bottom inside of the limiting seat 16 is embeddedly provided with a limiting cavity 17. The top of the abutting rod 15 penetrates and is slidably engaged in the inside of the limiting cavity 17.

[0038] The bottom end side of the abutting rod 15 close to the abutting plate 19 is fixedly installed with an abutting block one 18, one side of the abutting block one 18 is fixedly installed with an abutting block two 22, the adjacent surfaces of the abutting block one 18 and the abutting block two 22 are both arc-shaped, the top end sides and the bottom end sides of the abutting plate 19 are both slidably installed with guide rods 20, one end of the guide rod 20 is fixedly installed outside one side of the storage table 3, the outside of the guide rod 20 is sleeved with a reset spring 21, both ends of the reset spring 21 are fixedly installed on one side of the storage table 3 and the abutting plate 19, one end of the abutting block two 22 is fixedly installed outside one side of the abutting plate 19.

[0039] The inside of each limiting block 10 and the hollow shaft 13 of the corresponding side are both slidably installed with a roller rod 24, the inside of one side of the abutting plate 19 close to the roller rod 24 is longitudinally embedded with a limiting sliding groove 23, the rollers of the roller rod 24 are slidably installed inside one side of the limiting sliding groove 23, the end of the roller rod 24 away from the limiting sliding groove 23 is fixedly installed with a supporting frame 25, the supporting frame 25 is C-shaped in side view.

[0040] The outside of one side of the supporting frame 25 close to the roller rod 24 is symmetrically fixedly installed with an auxiliary rod 26, the inside of one side of the limiting block 10 close to the auxiliary rod 26 is embedded with an auxiliary groove 27, one end of the auxiliary rod 26 is slidably and abuttingly installed inside the auxiliary groove 27 of the corresponding side, the outside of one side of the roller rod 24 is sleeved with a compression spring 28, both ends of the compression spring 28 are fixedly installed on one side of the outside of the hollow shaft 13 and the roller rod 24.

[0041] Specifically, the auxiliary rod 26 and the auxiliary groove 27 are arranged, so that the supporting frame 25 can be more stable when it is stretched out or retracted, and the overall operation is stable.

[0042] In this embodiment, the multi-layer thermoelectric separation copper substrate production and processing feeding device is used. First, the existing inserting mechanism is used to place a stack of copper substrates on the top end of the placing seat 6. Then, the two side cylinders 14 are started to extend. The cylinder 14 will drive the top end of the contact rod 15 to extend synchronously. The contact rod 15 will drive the side contact block 18 to lift synchronously when it extends. When the contact block 18 extends a certain distance, the contact block 18 and the contact block 22 on one side of the contact plate 19 are separated, so that the contact plate 19 loses the contact limit. At this time, the reset spring 21 on the side of the contact plate 19 rebounds, thereby driving the contact plate 19 to press the side roller rod 24 to move. The roller rod 24 will drive the C-shaped support bracket 25 on one side to extend synchronously when it moves, so that the support bracket 25 stably inserts, lifts and limits the two sides of the copper substrate, ensuring the stability during subsequent splitting. At the same time, due to the limiting cavity 17 between the contact rod 15 and the limiting seat 16, the contact block 18 and the contact block 22 are separated. After the support bracket 25 extends to lift the copper substrate, the top end of the contact rod 15 will contact the top wall of the limiting cavity 17 in the limiting seat 16. Then, the limiting seat 16 is lifted, so that the cylinder 14 has a certain virtual position when it extends, avoiding the situation that the limiting block 10 starts to move for splitting before the support bracket 25 lifts the copper substrate, ensuring the stability of the overall splitting operation.

[0043] It should be noted that through the connection of the X-shaped connecting rods 11, the positioning rotation of the positioning pull rods 12 and the installation of the hollow shafts 13 and the limiting blocks 10, when the cylinder 14 drives the limiting seat 16 to lift, the side limiting blocks 10 will be lifted synchronously and orderly in the limiting grooves 9. When lifting, gaps will appear between the limiting blocks 10, so that gaps will also appear between the copper substrates supported by the limiting blocks 10 on one side of the support bracket 25, thereby completing the splitting of the stacked copper substrates, effectively breaking the oil film adhesion, making each multi-layer thermoelectric separation copper substrate independently suspended, thereby facilitating the precise adsorption of the suction cup mechanical arm 5, solving the feeding failure, avoiding the situation of feeding two or more substrates at a time, thereby improving the stability and production efficiency of the overall feeding, making the overall feeding effect better. After the cylinder 14 drives the copper substrate to split and stop running, the wiping assembly is controlled to run to wipe and clean the oil film on the surface of the copper substrate.

[0044] It also needs to be explained that when the wiping assembly wipes off the oil film on the surface of the copper substrate, the cylinder 14 is controlled to operate again. When the cylinder 14 is recovered to a certain extent again, the abutting block 18 abuts against the abutting block 22 again, so that the abutting block 22 is driven by the abutting pressure to expand and reset the abutting plate 19. When the abutting plate 19 is reset, the side of the roller rod 24 will also lose the extrusion force at this time, so that the side compression spring 28 drives the roller rod 24 and the supporting bracket 25 installed on one side to move back synchronously, so that the supporting bracket 25 is separated from the copper substrate, so that the copper substrate is separated and cleaned and is recycled and stacked again, which is convenient for subsequent placement of the seat 6 to be lifted for subsequent feeding.

[0045] Embodiment two: please refer to Figure 10 Figure 13 The embodiment is a further description of embodiment one.

[0046] The wiping assembly includes a plurality of limiting holes 29, a fixed frame 30 and a plurality of wiping belts 33. The plurality of limiting holes 29 are equidistantly and penetratively arranged on one side of the storage table 3. The fixed frame 30 is fixedly installed on one side of the storage table 3 near the plurality of limiting holes 29. The plurality of wiping belts 33 are equidistantly arranged on one side of the fixed frame 30 near the plurality of limiting holes 29.

[0047] The fixed frame 30 is externally and slidingly and clampingly installed with a mounting frame 31. The fixed frame 30 is fixedly installed with a cylinder 32 at a middle position on one side thereof. The output end of the cylinder 32 is fixedly installed with a mounting frame 31 at a middle position on one side thereof. The two sides of each wiping belt 33 are internally and abuttingly provided with two transmission rollers 34. The two ends of the two transmission rollers 34 are externally and rotatably installed on one side of the mounting frame 31.

[0048] The outer side of each wiping belt 33 is externally and fixedly provided with a chain wheel 35. The chain wheel 35 is transmissionally and connectingly provided with a chain 36 between the chain wheels 35. The mounting frame 31 is fixedly installed with a driving motor 37 on one side thereof. The output shaft of the driving motor 37 is coaxially and fixedly installed with one end of one of the transmission rollers 34. The mounting frame 31 is fixedly installed with an abutting scraper 38 on one side thereof away from the limiting hole 29. One side of the abutting scraper 38 is externally and abuttingly provided with one of the wiping belts 33.

[0049] ​In the embodiment, when the split assembly separates the stacked copper substrates, the one side cylinder two 32 is controlled to run out, the output end of the cylinder two 32 extends to drive the one side mounting frame 31 to slide synchronously in the fixed frame 30, and the mounting frame 31 drives the plurality of wiping belts 33 to move synchronously when sliding, so that the wiping belts 33 extend to the one side of the limiting hole 29 and are inserted between the separated copper substrates. Then, the one side driving motor 37 is started, the output shaft of the driving motor 37 rotates to drive the one side transmission roller 34 to rotate, and the chain wheel 35 and the chain 36 are driven to rotate, so that the plurality of wiping belts 33 rotate to wipe the surface of the copper substrate, thereby wiping the bottom surface and the top end of the copper substrate evenly. After the wiping assembly is processed, the oil film on the surface of the substrate is removed, so that the negative influence of the oil film on the suction force of the suction cup is eliminated, the suction cup can stably and reliably grasp the copper substrate, the problem that the oil film produces carbide during welding to affect the welding quality is avoided, the occurrence rate of defects such as virtual welding and separation is effectively reduced, a strong guarantee is provided for the subsequent welding process and the smooth progress of the entire production process, the processing quality and production efficiency of the product are greatly improved, and the wiping belt 33 is in contact with the fixed abutting scraper 38 during rotation, the impurities and oil stains on the surface of the wiping belt 33 are scraped off by the abutting scraper 38, the surface of the wiping belt 33 is cleaned, and the continuous use effect of the wiping belt 33 is ensured.
