Description

Technical Field

[0002] In everyday life, "chip" is a general term for semiconductor components, also known as microcircuit, microchip, or wafer / chip. In electronics, it is a way to miniaturize circuits and is often manufactured on the surface of semiconductor wafers. There are many types of chips, and neuromorphic chips are one of them. When assembling neuromorphic chips, it is usually necessary for skilled technicians to manually bond the electronic components on the chip. During this process, bonding equipment is needed to effectively fix the chip, and then skilled technicians manually bond the electronic components on the chip.

[0003] When bonding neuromorphic chips, the processing angle must be frequently adjusted due to the large number of electronic circuits in the chips. This allows workers to precisely process the chips.

[0022] like Figure 1-4 As shown, the specific implementation adopts the following technical solution:

[0023] Example:

[0024] A neuromorphic chip bonding device with flip-chip function includes a base plate 1. Four first cylinders 2 are fixedly connected to one end of the top of the base plate 1. A horizontal plate 3 is fixedly connected between the piston rods of the first cylinders 2. By controlling the operation of the first cylinders 2, the horizontal plate 3 can be moved up and down more easily, thereby adjusting the height of the horizontal plate 3 for convenient operation. A vertical plate 4 is fixedly connected to one end of the top of the horizontal plate 3. A top plate 5 is fixedly connected to the top of the vertical plate 4. A conveying mechanism 6 is provided at the top of the horizontal plate 3 and below the top plate 5. Second cylinders 7 are fixedly installed at both ends of the bottom of the top plate 5. The piston rods of cylinders 7 are all fixedly connected to clamping plates 8. By controlling the operation of the second cylinder 7, it is easier to drive the clamping plates 8 downward, thereby better fixing the neuromorphic chip that needs to be joined. A first mounting plate 11 is fixedly connected to the top of the base plate 1 and to one side of the first cylinder 2. A second mounting plate 12 is fixedly connected to the top of the base plate 1 and to one side of the first mounting plate 11. A third mounting plate 13 is fixedly connected to the top of the base plate 1 away from the first mounting plate 11. A second servo motor 14 is fixedly mounted on the side of the first mounting plate 11 away from the second mounting plate 12. Mounting plate 11 facilitates better installation and fixation of the second servo motor 14. The output shaft of the second servo motor 14 passes through the first mounting plate 11 and is fixedly connected to a rotating rod 15. The end of the rotating rod 15 away from the second servo motor 14 passes through the second mounting plate 12 and the third mounting plate 13. A second drive wheel 16 is fixedly connected to the outer side of the rotating rod 15 and to one side of the second mounting plate 12 and the third mounting plate 13. A rotating shaft 17 is rotatably connected to the top of the second mounting plate 12 and the third mounting plate 13, which facilitates better installation of the rotating shaft 17. The two rotating shafts 17 are mounted such that their ends, which are far apart, pass through the corresponding second mounting plate 12 and third mounting plate 13 and are fixedly connected to a second driven wheel 18. The second driven wheel 18 is connected to the corresponding second driving wheel 16 via a transmission belt 19. The second servo motor 14 is controlled to work, driving the rotating rod 15 to rotate, thereby driving the two second driving wheels 16 to rotate. The two second driven wheels 18 are driven to rotate simultaneously via the transmission belt 19, thereby driving the rotating shaft 17 to rotate, thus better completing the flipping control operation. The two rotating shafts 17 are also provided with a positioning mechanism 20 at their ends that are close together.

[0025] The conveying mechanism 6 includes a first fixed plate 61. Two first fixed plates 61 are fixedly connected to the top end of the horizontal plate 3 away from the first mounting plate 11. A first drive wheel 62 is rotatably connected between the two first fixed plates 61. A first servo motor 63 is fixedly mounted on the outer side of one of the first fixed plates 61. The output shaft of the first servo motor 63 passes through the corresponding first fixed plate 61 and is fixedly connected to the first drive wheel 62. Two second fixed plates 64 are fixedly connected to the top end of the horizontal plate 3 away from the first fixed plate 61. A first driven wheel 65 is rotatably connected between the two second fixed plates 64. The first driven wheel 65 and the first drive wheel 62 are connected by a conveyor belt 66. By controlling the first servo motor 63 to work, the first drive wheel 62 between the two first fixed plates 61 is driven to rotate. Thus, through the action of the conveyor belt 66, the first driven wheel 65 between the two second fixed plates 64 is driven to rotate, thereby better completing the conveying operation of the neuromorphic chip.

[0026] The positioning mechanism 20 includes a rotating plate 201. The two rotating shafts 17 are fixedly connected to the adjacent ends of the rotating plate 201. A third cylinder 202 is fixedly installed on the opposite sides of the top and bottom of each rotating plate 201. The piston rod of each third cylinder 202 passes through the corresponding rotating plate 201. A positioning plate 203 is fixedly connected between the piston rods of the two corresponding third cylinders 202. A through groove 204 is provided on the outer side of each positioning plate 203. Two sliding rods 205 are fixedly connected inside each through groove 204. A sliding strip 206 is slidably connected between the two sliding rods 205. An upper limit roller 207 is equidistantly rotatably connected to the side of each sliding strip 206 away from the rotating plate 201. A push plate 208 is fixedly connected to the top of each sliding strip 206 near the rotating plate 201. A connecting plate 209 is fixedly connected to the side of plate 203 near the rotating plate 201 and above the through groove 204. A fourth cylinder 2010 is fixedly installed at both ends of the top of the connecting plate 209. The piston rod of the fourth cylinder 2010 extends to the bottom of the connecting plate 209 and is fixedly connected to the top of the corresponding push plate 208. A lower limit roller 2011 that cooperates with the upper limit roller 207 is rotatably connected at equal intervals to the side of the positioning plate 203 away from the rotating plate 201 and below the through groove 204. Both the upper limit roller 207 and the lower limit roller 2011 are made of silicone. By setting the positioning mechanism 20, the neuromorphic chip being flipped can be positioned, which makes it convenient for the operator to accurately process the chip from different processing angles, thereby greatly improving the bonding processing efficiency and benefiting practical applications and operations.

[0027] The clamping plates 8 are all made of silicone material, which facilitates better protection of the chip.

[0028] A lighting lamp 9 is fixedly installed at the bottom of the top plate 5 and between the two second cylinders 7. The lighting lamp 9 facilitates better lighting operation.

[0029] The width of the conveyor belt 66 is always greater than the straight-line distance between the two positioning plates 203, which facilitates better conveying and positioning of chips of different widths.

[0030] In this configuration, a transmission box 2012 is fixedly connected to the bottom of the positioning plate 203 near the rotating plate 201. The central shaft of each lower limit roller 2011 extends into the corresponding transmission box 2012 and is fixedly connected to a sprocket 2013. The sprockets 2013 are connected to each other via a chain 2014. A third servo motor 2015 is fixedly installed on the side of the transmission box 2012 away from the positioning plate 203. The output shaft of each third servo motor 2015 extends into the corresponding transmission box 2012 and is fixedly connected to one of the sprockets 2013. By controlling the third servo motor 2015 to work, one of the sprockets 2013 is driven to rotate. Thus, through the action of the chain 2014, all the sprockets 2013 are driven to rotate, which in turn drives all the lower limit rollers 2011 to rotate. The rotation of the lower limit rollers 2011 and the cooperation between the upper limit rollers 207 facilitate the better delivery of the processed chip.

[0031] The number of upper limit rollers 207 and lower limit rollers 2011 is the same, which facilitates more stable positioning and conveying of the two ends of the chip.

[0032] An electrical control box 10 is fixedly installed on the top of the base plate 1 and between the two first cylinders 2. The first cylinder 2, the first servo motor 63, the second cylinder 7, the lighting lamp 9, the second servo motor 14, the third cylinder 202, the fourth cylinder 2010, and the third servo motor 2015 are all electrically connected to the electrical control box 10, which facilitates better control of the entire equipment.

[0033] The usage of this invention is as follows: Place the device in the designated location, then power on the device. Place the neuromorphic chip to be bonded onto the conveyor belt 66. Then, control the second cylinder 7 via the control box 10 to move the clamping plate 8 downwards, thereby fixing the neuromorphic chip to be bonded to the top of the conveyor belt 66. Then, perform the bonding operation at a fixed angle. After processing, control the first cylinder 2 via the control box 10 to move the horizontal plate 3 up and down, thereby adjusting the horizontal plate 3 relative to the neuromorphic chip. The height is adjusted to match the position of the lower limit roller 2011. Then, the first servo motor 63 is controlled by the electrical control box 10 to drive the first drive wheel 62 between the two first fixed plates 61 to rotate. This, in turn, drives the first driven wheel 65 between the two second fixed plates 64 to rotate via the conveyor belt 66, thereby conveying the neuromorphic chip to the area above the lower limit roller 2011. Then, the fourth cylinder 2010 is controlled by the electrical control box 10 to drive the push plate 208 and the slide bar 206 to move downwards, thereby driving the upper limit roller 2011. 07 moves downwards, and the neuromorphic chip is positioned by the cooperation between the upper limit roller 207 and the lower limit roller 2011. After positioning, the second servo motor 14 is controlled by the control box 10 to drive the rotating rod 15 to rotate, thereby driving the two second driving wheels 16 to rotate. Through the transmission belt 19, the two second driven wheels 18 rotate simultaneously, thereby driving the rotating shaft 17 to rotate, which in turn drives the rotating plate 201 and the positioning plate 203 to rotate, thus completing the flipping control operation of the neuromorphic chip, which facilitates the operator. The operator performs precise processing on the chip from different processing angles, which greatly improves the bonding processing efficiency and is beneficial to practical applications and operations. After the bonding processing is completed, the third servo motor 2015 can be controlled by the electrical control box 10 to drive one of the sprockets 2013 to rotate. Then, through the action of the chain 2014, all the sprockets 2013 are driven to rotate, which in turn drives all the lower limit rollers 2011 to rotate. Through the rotation of the lower limit rollers 2011 and the cooperation between the upper limit rollers 207, the processed chip is transported out.
