Description
Technical Field
[0001] The present invention relates to the technical field of glue dispensing, and in particular to a glue dispensing structure, a glue dispensing method and a glue dispensing device for a GPU chip. Background Art
[0002] GPU chip is a high-performance integrated circuit chip specially used to process graphics rendering, parallel computing and artificial intelligence tasks. In the chip production process, the dispensing structure is the core functional carrier of the packaging link, which makes up for the physical defects of the chip in mechanical strength, thermal management and environmental protection.
[0003] The existing dispensing structure is mostly composed of a robot, a translation stage, a cylinder and a dispenser. Its working principle is as follows: first, the chip to be dispensed is placed on the translation stage, and then the cylinder drives the dispenser to descend close to the chip. At this time, the chip can be dispensed. The robot can control the dispenser to move along the X-axis through the cylinder, and the translation stage controls the chip to move along the Y-axis, thereby changing the dispensing position of the dispenser. Finally, the chip that has been dispensed is removed to complete the chip dispensing process.
[0004] After the glue dispenser completes the glue dispensing operation, it needs to perform a lifting action to provide space for chip transfer. However, due to the viscosity of the glue material itself, the glue dispenser is prone to form trace amounts of glue residue or filamentous entanglement at the glue outlet during the lifting process. This type of wire drawing phenomenon may cause the glue filaments to adhere to the chip functional area or the carrier surface, thereby causing risks such as product contamination and increased equipment maintenance costs. Therefore, this application proposes a glue dispensing structure, glue dispensing method and glue dispensing equipment for GPU chips. Summary of the Invention

DETAILED DESCRIPTION
[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 making creative work are within the scope of protection of the present invention.
[0021] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.
[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0023] After the glue dispenser 7 completes the glue dispensing operation, it needs to be lifted to provide space for chip transfer. However, due to the viscosity of the glue material itself, the glue dispenser 7 is prone to form trace amounts of glue residue or filamentous entanglement at the glue outlet during the lifting process. This type of wire drawing phenomenon may cause the glue filaments to adhere to the chip functional area or the carrier surface, thereby causing risks such as product contamination and increased equipment maintenance costs.
[0024] In response to the above problems, Figure 1 - Figure 4 As shown, the present invention proposes a dispensing structure for a GPU chip, including a connecting frame 4, a cylinder 5 is installed on the outside of the connecting frame 4, and the output end of the cylinder 5 is connected to a lifting platform 6. When the cylinder 5 is running, it can drive the lifting platform 6 to descend, and a dispensing device 7 is installed inside the lifting platform 6. When the lifting platform 6 descends, the dispensing device 7 will drive the dispensing device 7 to descend close to the chip to be dispensing, and then the dispensing device 7 starts to perform dispensing operation on the chip. It should be noted that the cylinder 5 and the dispensing device 7 are both existing technologies, and the technology is mature, so no further explanation is needed.
[0025] As an implementation method, Figure 2 - Figure 5 As shown, this embodiment also includes at least two groups of symmetrically distributed arc plates 8, both ends of the arc plates 8 are fixed with L rods 9, one end of the L rod 9 away from the arc plates 8 is fixed to the outer side of the lifting platform 6, and the L rod 9 supports the arc plates 8; the rubber roller 10 is rotatably installed inside the two groups of arc plates 8, and the two ends of the rubber roller 10 are limited by the two groups of arc plates 8, thereby ensuring that the rubber roller 10 moves between the two groups of arc plates 8, and the rubber roller 10 breaks the drawing glue at the glue outlet of the glue dispenser 7 when moving inside the arc plates 8; the traction mechanism is connected to the cylinder 5, and is used to pull the rubber roller 10 to move when the glue dispenser 7 descends. When the cylinder 5 drives the lifting platform 6 to descend, the L rod 9 will synchronously drive the arc plate 8 to descend, and the descent of the arc plate 8 will drive the rubber roller 10 to descend. At this time, the traction mechanism will run under the action of the descent of the rubber roller 10, thereby driving the rubber roller 10 to move along the inside of the arc plate 8. After the dispenser 7 moves down a certain distance, the traction mechanism will pull the rubber roller 10 over the dispenser 7, and then the dispenser 7 will descend and stop. Under the action of the traction mechanism, the rubber roller 10 will synchronously remain stationary, waiting for the dispenser 7 to carry out the dispensing operation. It should be noted that the rubber roller 10 will not touch the glue outlet of the dispenser 7 when moving.
[0026] Further, such as Figure 5 and Figure 6As shown, this embodiment also includes a reset mechanism for driving the rubber roller 10 to move in the opposite direction when the dispenser 7 rises, and when the rubber roller 10 moves, the rubber roller 10 will squeeze the reset mechanism, so that the reset mechanism generates elastic potential energy. When the dispensing operation of the dispenser 7 is completed, the dispenser 7 rises, and the reset mechanism will push the rubber roller 10 to move in the opposite direction and reset. In the process of resetting the rubber roller 10, the rubber roller 10 will pass over the dispenser 7 again. At this time, when the rubber roller 10 is reset, it will squeeze the drawing glue produced by the glue outlet of the dispenser 7, and the drawing glue will be disconnected under the force, thereby avoiding the problem that the drawing glue will follow the dispenser 7 and adhere to other areas during the subsequent operation of the dispenser 7, causing product contamination.
[0027] When the viscosity of the glue is relatively high, the drawing glue may not break when the rubber roller 10 squeezes the drawing glue, causing the glue thread to be transferred from the glue outlet of the glue dispenser 7 to the outside of the rubber roller 10, so that the glue thread is connected between the rubber roller 10 and the chip.
[0028] In response to the above problems, such as Figure 7 As shown, this embodiment also includes a rotating mechanism, which is arranged on the periphery of the rubber roller 10 and is used to drive the rubber roller 10 to rotate when it moves, so that the drawing glue is wrapped around the outside of the rubber roller 10. Under the action of the traction mechanism and the reset mechanism, the rubber roller 10 will move and reset along the inside of the arc plate 8. In this process, the movement of the rubber roller 10 will also drive the operation of the rotating mechanism, and the operation of the rotating mechanism will drive the rubber roller 10 to rotate. At this time, the rotation of the rubber roller 10 will wrap the rubber wire around the outside of the rubber roller 10. Since the diameter of the rubber wire is relatively thin, when the rubber roller 10 rotates, the rubber roller 10 will continuously wrap and pull the rubber wire. The diameter of the rubber wire is continuously reduced due to the force, and a progressive winding effect is generated as the rubber roller 10 rotates. Finally, the residual rubber wire is completely removed by physical pulling, eliminating the risk of secondary pollution.
[0029] As an implementation method, Figure 4 and Figure 5 As shown, the traction mechanism includes a traction rope 11, a connecting ring 12, a guide wheel 13, a fixing plate 14, a guide wheel 2 15 and a guide wheel 3 16. The traction mechanism is described in detail below: The traction rope 11 is fixedly connected to the outer side of the cylinder 5, and the connecting ring 12 is rotatably connected to the outer side of the rubber roller 10, and the connecting ring 12 is fixedly connected to the end of the traction rope 11 away from the cylinder 5. When the rubber roller 10 descends, it will synchronously drive the connecting ring 12 to descend, and when the connecting ring 12 descends, it will pull the traction rope 11. Due to the limited distance of the traction rope 11, as the rubber roller 10 descends, the traction rope 11 will pull the connecting ring 12, and the connecting ring 12 will move under the force, thereby driving the rubber roller 10 to move along the inside of the arc plate 8, so that the rubber roller 10 passes over the glue outlet of the glue dispenser 7. When the glue dispenser 7 is stationary, the rubber roller 10 no longer descends, and the traction rope 11 drives the rubber roller 10 to be in a stationary state. The fixed plate 14 is fixedly connected to the outer side of the arc plate 8, and the guide wheel 13 is fixedly connected to the fixed plate 14. The fixed plate 14 supports the guide wheel 13. The guide wheel 2 15 and the guide wheel 3 16 are both fixedly connected to the outer side of the cylinder 5. The traction rope 11 is attached to the outer sides of the guide wheel 13, the guide wheel 2 15 and the guide wheel 3 16. The guide wheel 13, the guide wheel 2 15 and the guide wheel 3 16 guide the traction position of the traction rope 11.
[0030] Further, such as Figure 5 and Figure 6 As shown, the reset mechanism includes a limit block 17 and a spring 18. The reset mechanism is described in detail below: The limit block 17 is sleeved on the outside of the rubber roller 10. When the rubber roller 10 moves, it will synchronously drive the limit block 17 to move, and the limit block 17 is slidably connected to the inside of the arc plate 8. The limit block 17 will move along the inside of the arc plate 8 at this time. The two ends of the spring 18 are respectively fixed to the inner wall of the arc plate 8 and the limit block 17, and when the limit block 17 moves, the limit block 17 will also squeeze the spring 18, causing the spring 18 to deform and generate elastic potential energy. When the rubber roller 10 rises and resets, the traction rope 11 gradually stops pulling the rubber roller 10 through the connecting ring 12, and the squeezing of the spring 18 by the limit block 17 gradually stops. The spring 18 will release the elastic potential energy and push the rubber roller 10 to move in the opposite direction and reset through the limit block 17.
[0031] Furthermore, Figure 7 As shown, the rotating mechanism includes a spur gear 19, an arc-shaped rack 20 and a connecting plate 21. The rotating mechanism is described in detail below: The spur gear 19 is fixedly connected to the outer side of the rubber roller 10. When the rubber roller 10 moves, the spur gear 19 is synchronously driven to move. The arc-shaped rack 20 is meshed with the outer side of the spur gear 19. During the movement of the spur gear 19, it will rotate under the action of the meshing of the arc-shaped rack 20. The rotation of the spur gear 19 drives the rubber roller 10 to rotate. When the rubber roller 10 is reset, the spur gear 19 also drives the rubber roller 10 to rotate. At this time, when the rubber roller 10 is reset to extrude the rubber wire, under the action of the spur gear 19, the rubber roller 10 will rotate to wrap the rubber wire around its outer side. The connecting plate 21 is fixedly connected to the outer side of the arc-shaped rack 20, and the end of the connecting plate 21 away from the arc-shaped rack 20 is fixedly connected to the arc plate 8. The connecting plate 21 supports the arc-shaped rack 20 to prevent the arc-shaped rack 20 from falling.
[0032] As an implementation method, Figure 8 and Figure 9 As shown, a pair of slide grooves 22 are provided on the outer side of the rubber roller 10, and a driving plate 23 is slidably connected to the outer side of the slide groove 22. When there is a lot of rubber wire wrapped around the outer side of the rubber roller 10, the driving plate 23 can be moved manually. When the driving plate 23 moves, it will move along the inside of the slide groove 22, pushing the rubber wire wrapped around the outer side of the rubber roller 10. At this time, the rubber wire is squeezed by the edge of the driving plate 23 and will move synchronously with the driving plate 23. Four groups of pressure rods 24 are fixed to the outer side of the driving plate 23, and the movement of the driving plate 23 will also drive the four groups of pressure rods 24 to move. The end of the rubber roller 10 away from the driving plate 23 is fixed with a storage bin 25, and the interior of the storage bin 25 is slidably connected to four groups of baffles 26. The periphery of the baffle 26 is provided with a closing mechanism, which is used to drive the rubber wire in a stationary state. The four groups of baffles 26 are fitted to the outside of the rubber roller 10, and the pressure rod 24 opens when squeezing the closing mechanism, so that the four groups of baffles 26 end fitting with the rubber roller 10. After the pressure rod 24 moves a certain distance toward the storage bin 25, the pressure rod 24 drives the closing mechanism to operate, and the operation of the closing mechanism drives the four groups of baffles 26 to move in the direction away from the rubber roller 10, opening the inside of the storage bin 25. The driving plate 23 can push the rubber wire to the inside of the storage bin 25 when moving. Then, the driving plate 23 is moved in the opposite direction to reset, and the control of the closing mechanism by the driving plate 23 ends. The closing mechanism drives the four groups of baffles 26 to reset, so that it fits the outside of the rubber roller 10, and seals the residual rubber wire inside the storage bin 25, thereby avoiding the dripping of the rubber wire and causing pollution.
[0033] Among them, such as Figure 8 and Figure 9 As shown, the closing mechanism includes an inclined block 27, a horizontal plate 28, a pair of limiting rods 29, a top plate 30 and a second spring 31. The closing mechanism is described in detail below: The inclined block 27 and the cross plate 28 are both fixedly connected to the outer side of the baffle 26. When the pressure rod 24 moves a certain distance toward the storage bin 25, the pressure rod 24 will squeeze the inclined surface of the inclined block 27. It should be noted that there is a certain distance between the inclined block 27 and the cross plate 28, and the pressure rod 24 will not collide with the cross plate 28. The inclined block 27 will move under the force at this time, and the movement of the inclined block 27 will drive the baffle 26 and the cross plate 28 to move synchronously. When the baffle 26 moves, it will break away from the fit with the rubber roller 10. At this time, the rubber wire can be moved to the inside of the storage bin 25 under the push of the drive plate 23. A pair of limit rods 29 are both fixedly connected to the storage bin 25. The outer side of the bin 25 is fixed, and the limit rod 29 passes through the transverse plate 28. The top plate 30 is fixed to the end of the limit rod 29 away from the storage bin 25. The spring 2 31 is fixed between the storage bin 25 and the transverse plate 28. When the transverse plate 28 moves, it will pull the spring 2 31 under the limit of the limit rod 29, causing the spring 2 31 to deform and generate elastic potential energy. After the pressure rod 24 finishes squeezing the inclined block 27, the spring 2 31 will release the elastic potential energy and pull the transverse plate 28 to reset. The reset of the transverse plate 28 will drive the inclined block 27 to reset through the baffle 26. At this time, the baffle 26 is again attached to the outer side of the rubber roller 10 to seal the storage bin 25.
[0034] Further, such as Figure 8 and Figure 9 As shown, there are four groups of closing mechanisms, which are arranged in a circular array on the outside of the storage bin 25. If four groups of closing mechanisms are provided, the four groups of baffles 26 can be controlled to achieve simultaneous movement and resetting of the four groups of baffles 26.
[0035] Furthermore, Figure 9 As shown, the baffle 26 is made of fluororubber, which can improve the sealing between the baffle 26 and the rubber roller 10, ensuring good sealing inside the storage bin 25.
[0036] As an implementation method, Figure 1 - Figure 3 As shown, the present application provides a dispensing device for GPU chips, including a dispensing table 1, a translation table 2, a manipulator 3 and a connecting frame 4, and a dispensing structure for the GPU chip arranged on the periphery of the manipulator 3. The dispensing structure can process the glue filaments produced by the dispenser 7 to prevent contamination caused by the glue filaments. The translation table 2 is installed on the top of the dispensing table 1, and the chip to be dispensed is placed on the translation table 2. The translation table 2 is a prior art and the technology is mature. It can drive the chip to move along the Y axis. The manipulator 3 is arranged on both sides of the dispensing table 1, and the connecting frame 4 is installed on the outside of the manipulator 3. The manipulator 3 can drive the connecting frame 4 to move along the X axis, so that its dispenser 7 can change the dispensing position. The manipulator 3 is also a prior art and the technology is mature, so it will not be elaborated in detail.
[0037] A method for dispensing a GPU chip, the method comprising the following steps: S1: When the cylinder 5 drives the lifting platform 6 to descend, the L rod 9 will synchronously drive the arc plate 8 to descend, and the arc plate 8 will drive the rubber roller 10 to descend. At this time, the traction mechanism will operate under the action of the rubber roller 10 descending, thereby driving the rubber roller 10 to move along the inside of the arc plate 8; S2: After the glue dispenser 7 moves down a certain distance, the traction mechanism pulls the rubber roller 10 over the glue dispenser 7, and then the glue dispenser 7 descends and stops. Under the action of the traction mechanism, the rubber roller 10 remains stationary, waiting for the glue dispenser 7 to start the glue dispensing operation; S3: When the rubber roller 10 moves, the rubber roller 10 squeezes the reset mechanism, causing the reset mechanism to generate elastic potential energy. When the dispensing operation of the glue dispenser 7 is completed, the glue dispenser 7 rises, and the reset mechanism pushes the rubber roller 10 to move in the opposite direction and reset. S4: During the process of resetting the rubber roller 10, the rubber roller 10 will pass over the glue dispenser 7 again. At this time, when the rubber roller 10 is resetting, it will squeeze the drawing glue produced by the glue outlet of the glue dispenser 7, and the drawing glue will be broken by the force.
[0038] In this embodiment, the chip to be glued is placed on the translation stage 2, the translation stage 2 can drive the chip to move along the Y axis, the manipulator 3 can drive the connecting frame 4 to move along the X axis, the connecting frame 4 is connected to the cylinder 5 and the lifting platform 6, so that the glue dispenser 7 can change the X axis position of the glue dispenser. When the cylinder 5 is running, it can drive the lifting platform 6 to descend, and the descent of the lifting platform 6 will drive the glue dispenser 7 to descend close to the chip to be glued, and then the glue dispenser 7 starts to glue the chip, and when the cylinder 5 drives the lifting platform 6 to descend, the L rod 9 will synchronously drive the arc plate 8 to descend, and the arc The plate 8 descends and drives the rubber roller 10 to descend. When the rubber roller 10 descends, it will synchronously drive the connecting ring 12 to descend. When the connecting ring 12 descends, it will pull the traction rope 11. Since the distance of the traction rope 11 is limited, as the rubber roller 10 descends, the traction rope 11 will pull the connecting ring 12, and the connecting ring 12 will move under the force, thereby driving the rubber roller 10 to move along the inside of the arc plate 8, so that the rubber roller 10 passes the glue outlet of the glue dispenser 7. When the glue dispenser 7 is stationary, the rubber roller 10 no longer descends, and the traction rope 11 drives the rubber roller 10 to be stationary. State, and when the rubber roller 10 moves, it will synchronously drive the limit block 17 to move. The limit block 17 will move along the inside of the arc plate 8 at this time. When the limit block 17 moves, the limit block 17 will also squeeze the spring 18, causing the spring 18 to deform and generate elastic potential energy. When the rubber roller 10 rises and resets, the traction rope 11 gradually stops pulling the rubber roller 10 through the connecting ring 12, and the spring 18 gradually stops being squeezed by the limit block 17. The spring 18 will release its elastic potential energy and push the rubber roller 10 to move in the opposite direction and reset through the limit block 17. When the rubber roller 10 is reset, it will squeeze the drawing glue produced by the glue outlet of the glue dispenser 7, and the drawing glue will be broken by the force. When the rubber roller 10 moves, it will synchronously drive the spur gear 19 to move. During the movement of the spur gear 19, it will rotate under the action of the meshing of the arc-shaped rack 20. The rotation of the spur gear 19 drives the rubber roller 10 to rotate. When the rubber roller 10 is reset, the spur gear 19 also drives the rubber roller 10 to rotate. At this time, when the rubber roller 10 is reset to squeeze the rubber wire, under the action of the spur gear 19, the rubber roller 10 will rotate to wrap the rubber wire around its outside; When there is a lot of rubber wire wrapped around the outside of the rubber roller 10, the driving plate 23 can be moved manually. When the driving plate 23 moves, it will move along the inside of the slide groove 22, pushing the rubber wire wrapped around the outside of the rubber roller 10. The rubber wire is squeezed by the edge of the driving plate 23 at this time and will move synchronously with the driving plate 23. The movement of the driving plate 23 will also drive the four sets of pressure rods 24 to move. When the pressure rods 24 move a certain distance toward the storage bin 25, the pressure rods 24 will squeeze the inclined surface of the inclined block 27. The inclined block 27 will move under the force at this time, and the movement of the inclined block 27 will drive the baffle 26 and the cross plate 28 to move synchronously. When the baffle 26 moves, it will break away from the fit with the rubber roller 10. At this time, the rubber wire can be moved to the inside of the storage bin 25 under the push of the driving plate 23. When the cross plate 28 moves, it will pull the spring 2 31 under the limit of the limit rod 29, causing the spring 2 31 to deform and generate elastic potential energy. After the pressure rod 24 finishes squeezing the inclined block 27, the spring 2 31 will release the elastic potential energy and pull the cross plate 28 to reset. The reset of the cross plate 28 will drive the inclined block 27 to reset through the baffle 26. At this time, the baffle 26 is again fitted to the outside of the rubber roller 10 to seal the storage bin 25.
