[0052] Refer to the attached Figures 1-7 , this embodiment provides a base material baking device, including:
[0053] A baking rack, which includes:
[0054] A first plate body 1, which is arranged in the vertical direction;
[0055] A second plate body 2, which is arranged at the bottom end of the first plate body 1 in the horizontal direction;
[0056] A plurality of fixed screws 3, one end of which is fixed on the first plate body 1, and the other end extends in a direction perpendicular to the first plate body 1. The plurality of fixed screws 3 are arranged at intervals along the bottom edge of the first plate body 1;
[0057] A material winding and unwinding assembly, which includes a first winding shaft 7 and a second winding shaft 8. The first winding shaft 7 and the second winding shaft 8 are rotatably arranged on the first plate body 1 and are arranged below the plurality of fixed screws 3;
[0058] A plurality of ball screw pairs 5, which are respectively arranged between adjacent fixed screws 3 and are fixed on the second plate body 2 in the vertical direction. The ball screw pair 5 includes a screw 501 and a nut 502; and
[0059] A plurality of moving screws 4 corresponding to the plurality of ball screw pairs 5, which are arranged in parallel with the plurality of fixed screws 3. One end of the moving screw 4 is connected to the nut 502 of the corresponding ball screw pair 5 to move under the drive of the nut 502, and the other end extends towards the first plate body 1;
[0060] A transmission assembly, which is connected to the baking rack and includes:
[0061] A first motor 10;
[0062] A transmission rod 11, which is connected to the output end of the first motor 10;
[0063] A plurality of transmission shafts 12 corresponding to the plurality of ball screw pairs 5. The plurality of transmission shafts 12 are parallel to each other and are arranged along the length direction of the transmission rod 11. The plurality of transmission shafts 12 are respectively connected to the transmission rod 11 through a helical gear mechanism, so that the plurality of transmission shafts 12 can rotate synchronously under the drive of the transmission rod 11. At the same time, the transmission shaft 12 is connected to the screw 501 of the corresponding ball screw pair 5 to drive the screw 501 to rotate; and
[0064] A second motor, the output end of which can be respectively connected to the first winding shaft 7 or the second winding shaft 8 to drive the first winding shaft 7 and the second winding shaft 8 to rotate;
[0065] Wherein, the first winding shaft 7, the second winding shaft 8, and the plurality of fixed screws 3 are all arranged on the same surface of the first plate body 1 and are arranged in parallel.
[0066] This embodiment provides a substrate 22 baking device, which includes a baking rack, a transmission assembly, and a second motor. The transmission assembly and the second motor are used to drive the baking rack to operate to spread the substrate 22 on the baking rack, and then place the baking rack covered with the substrate 22 in an oven to perform baking treatment on the substrate 22.
[0067] The baking rack is made of heat-resistant material as a whole and can be placed in an oven for treatment.
[0068] For key reference, please refer to the appendix Figures 1-4 , the baking rack includes a first plate body 1, a second plate body 2, a plurality of fixed screws 3, a plurality of moving screws 4, a plurality of ball screw pairs 5, and a material feeding and discharging assembly. Among them, the plurality of moving screws 4 and the plurality of ball screw pairs 5 are arranged in one-to-one correspondence.
[0069] The first plate body 1 is arranged in the vertical direction. The second plate body 2 is arranged horizontally at the bottom end of the first plate body 1, and the second plate body 2 is used to support the whole device. A moving wheel 6 is provided at the bottom end of the second plate body 2 to facilitate the movement of the baking rack.
[0070] One end of each of the plurality of fixed screws 3 is fixed on the first plate body 1, and the other end extends in a direction perpendicular to the first plate body 1. The plurality of fixed screws 3 are arranged at intervals along the bottom edge of the first plate body 1. The arrangement of the plurality of fixed screws 3 along the bottom edge of the first plate body 1 can make more use of the space of the first plate body 1, enabling the substrate 22 to be fully unfolded.
[0071] The material feeding and discharging assembly includes a first winding shaft 7 and a second winding shaft 8. One end of the first winding shaft 7 and the second winding shaft 8 is installed on the first plate body 1 through bearings, and the other end extends in a direction perpendicular to the first plate body 1. Thus, the first winding shaft 7 and the second winding shaft 8 are rotatably arranged on the first plate body 1 to facilitate the unfolding and winding of the substrate 22.
[0072] The first winding shaft 7, the second winding shaft 8, and the plurality of fixed screws 3 are all arranged on the same side of the first plate body 1, and their arrangement directions are parallel. The first winding shaft 7 and the second winding shaft 8 are arranged below the plurality of fixed screws 3. The first winding shaft 7 and the second winding shaft 8 are respectively arranged close to two opposite edges of the first plate body 1. If the first winding shaft 7 and the second winding shaft 8 are arranged close to each other, in order to ensure the smooth unfolding of the substrate 22, there needs to be a large longitudinal distance between the first winding shaft 7, the second winding shaft 8 and the plurality of fixed screws 3, resulting in an increase in the volume of the entire baking rack. Therefore, the first winding shaft 7 and the second winding shaft 8 are respectively arranged at the lower left corner and the lower right corner of the first plate body 1 to facilitate the unfolding and winding of the substrate 22 and save space.
[0073] The plurality of ball screw pairs 5 are respectively arranged between adjacent fixed screws 3 and are all fixed on the second plate body 2 in the vertical direction. The ball screw pair 5 includes a lead screw 501, a nut 502, an upper base 503, and a base 504. The two ends of the lead screw 501 are respectively installed in the upper base 503 and the base 504, and the nut 502 is installed on the lead screw 501 and moves linearly along the length direction of the lead screw 501.
[0074] The multiple moving screws 4 and the multiple ball screw pairs 5 are in one-to-one correspondence. The multiple moving screws 4 are arranged in parallel with the multiple fixed screws 3. One end of the moving screw 4 is connected to the nut 502 of the corresponding ball screw pair 5 to perform a linear motion driven by the nut 502, and the other end of the moving screw 4 extends in the direction close to the first plate body 1. The multiple moving screws 4 and the multiple fixed screws 3 are arranged in parallel and at intervals.
[0075] On the first plate body 1, there are multiple chutes 9 that are in one-to-one correspondence with the multiple moving screws 4. The multiple chutes 9 are horizontally arranged on the first plate body 1 and extend respectively along the height direction of the first plate body 1. One end of the moving screw 4 is fixed to the nut 502 of the ball screw pair 5, and the other end passes through the corresponding chute 9 so that the moving screw 4 can move between the bottom end and the top end of the chute 9. The setting of the chute 9 plays a role in limiting the movement of the moving screw 4 and also plays a role in positioning the highest and lowest points of its movement.
[0076] When the multiple moving screws 4 stop at the bottom ends of the chutes 9, the multiple moving screws 4 are all arranged below the multiple fixed screws 3 and are arranged along the bottom edge of the first plate body 1. This setting method can facilitate the substrate 22 to pass through the upper ends of the multiple moving screws 4. When unfolding the substrate 22, it only needs to pass the substrate 22 through the upper ends of the multiple moving screws 4 in sequence, instead of passing through the upper ends of the moving screws 4 and the lower ends of the fixed screws 3 one by one, thus facilitating the operation, reducing the operation time, and improving the efficiency.
[0077] The transmission component and the second motor are used to drive the baking rack to operate so as to realize the unfolding and winding of the substrate 22. The transmission component and the second motor are respectively connected to the baking rack and act on the baking rack together. At the same time, both the transmission component and the second motor can be easily separated from the baking rack so as to facilitate pushing the baking rack into the oven for baking, rather than baking together with the transmission component and the second motor, thereby protecting the transmission component and the second motor.
[0078] The transmission component includes a first motor 10, a transmission rod 11, and multiple transmission shafts 12 corresponding to the multiple ball screw pairs 5.
[0079] The transmission rod 11 is connected to the output end of the first motor 10, so that it can operate driven by the first motor 10.
[0080] The multiple transmission shafts 12 are arranged in one-to-one correspondence with the multiple ball screw pairs 5. The multiple transmission shafts 12 are parallel to each other. The multiple transmission shafts 12 are arranged along the length direction of the transmission rod 11. Each transmission shaft 12 is respectively connected to the transmission rod 11 through a helical gear mechanism. The helical gear mechanism includes a first helical gear 13 and a second helical gear 14 that mesh with each other. The first helical gear 13 is arranged on the transmission rod 11, and the second helical gear 14 is arranged on the corresponding transmission shaft 12. The axes of the first helical gear 13 and the second helical gear 14 are perpendicular.
[0081] A plurality of transmission shafts 12 are respectively connected to a transmission rod 11 through a helical gear mechanism, so that the plurality of transmission shafts 12 can rotate synchronously at the same speed under the drive of the transmission rod 11. One end of the transmission shaft 12 is rotatably connected to a support member 15, and the support member 15 is fixed to the ground, thereby further fixing the transmission shaft 12 and enabling the rotating shaft to operate stably. The other end of the transmission shaft 12 is connected to a lead screw 501 of a corresponding ball screw pair 5 to drive the lead screw 501 to rotate.
[0082] Since the setting direction of the transmission shaft 12 is perpendicular to the setting direction of the lead screw 501, if the transmission shaft 12 and the lead screw 501 are to be connected, the transmission shaft 12 needs to extend horizontally into the base 504 of the ball screw pair 5, or the bottom end of the lead screw 501 needs to extend out of the base 504, and the transmission shaft 12 is connected to the bottom end of the lead screw 501 from the bottom end of the base 504. Both of these setting methods are difficult to implement and inconvenient to operate. Therefore, in order to facilitate the connection between the transmission shaft 12 and the lead screw 501, a transfer shaft 16 is provided in this embodiment. The ball screw pair 5 is provided with a base 504, and the bottom end of the lead screw 501 is arranged in the base 504. A transfer shaft 16 is also arranged in the base 504. The transfer shaft 16 is perpendicular to the setting direction of the lead screw 501, and the transfer shaft 16 is parallel to the setting direction of the transmission shaft 12. The bottom end of the lead screw 501 is connected to the transfer shaft 16, and the end of the transfer shaft 16 away from the lead screw 501 extends out of the base 504 and is then connected to the transmission shaft 12. A third helical gear 17 is arranged at the bottom end of the lead screw 501, and a fourth helical gear 18 is arranged at the end of the transfer shaft 16 connected to the lead screw 501. The third helical gear 17 and the fourth helical gear 18 can mesh and their axes are perpendicular, so that the transfer shaft 16 can drive the lead screw 501 to operate. Thus, the connection between the transmission shaft 12 and the corresponding lead screw 501 through the transfer shaft 16 is realized.
[0083] During the unfolding or winding process of the base material 22, it is necessary to control the sequential movement of a plurality of moving screws 4. Therefore, a solenoid valve is provided in this embodiment. In this embodiment, the transmission shaft 12 is connected to a corresponding transfer shaft 16 through the solenoid valve. The solenoid valve is arranged on the transmission shaft 12 and can rotate under the drive of the transmission shaft 12. The output end of the solenoid valve faces the transfer shaft 16. The piston rod 19 of the solenoid valve can move towards or away from the transfer shaft 16, so that the piston rod 19 is connected to or separated from the transfer shaft 16.
[0084] For key reference, please Figures 5-7, a first mounting plate 20 is provided on the piston rod 19 of the solenoid valve, and four bumps 2001 are provided on the first mounting plate 20. One end of the transfer shaft 16 away from the fourth helical gear 18 is provided with a second mounting plate 21, and four grooves 2101 are correspondingly provided on the second mounting plate 21. When the piston rod 19 of the solenoid valve moves towards the transfer shaft 16, the bumps 2001 can be inserted into the grooves 2101 to connect the first mounting plate 20 and the second mounting plate 21, thereby realizing the connection between the transmission shaft 12 and the transfer shaft 16. At this time, the transmission shaft 12 drives the corresponding moving screw rod 4 to move through the ball screw pair 5. When the piston rod 19 of the solenoid valve moves away from the transfer shaft 16, the bumps 2001 can be pulled out of the grooves 2101 to separate the transmission shaft 12 and the transfer shaft 16. At this time, the corresponding moving screw rod 4 stops moving. The first mounting plate 20 and the second mounting plate 21 are circular plates with the same shape and size for easy installation.
[0085] Limit sensors are provided on each moving screw rod 4. When the moving screw rod 4 moves to the upper end of the chute 9 on the first plate body 1, the limit sensor on the moving screw rod 4 will transmit an instruction to its corresponding solenoid valve to close the air valve. Thus, the piston rod 19 of the solenoid valve moves away from the transfer shaft 16 to stop the movement of the moving screw rod 4. And the limit sensor on the moving screw rod 4 will simultaneously transmit an instruction to the solenoid valve corresponding to the adjacent moving screw rod 4 to open the air valve. Thus, the piston rod 19 of the solenoid valve moves towards its corresponding transfer shaft 16, and the adjacent moving screw rod 4 starts to move.
[0086] In this embodiment, the first motor 10 and the transmission rod 11 are also connected by a helical gear transmission method. The transmission rod 11 and the output shaft of the first motor 10 are connected by a connecting shaft 23. One end of the connecting shaft 23 is provided with a fifth helical gear 24, and the other end is connected to the first motor 10. A sixth helical gear 25 is correspondingly provided at the end of the transmission rod 11. The fifth helical gear 24 and the sixth helical gear 25 mesh with each other and the axes are perpendicular, so that helical gear transmission can be realized between the connecting shaft 23 and the transmission rod 11.
[0087] A third mounting plate is provided on the output shaft of the first motor 10, and a fourth mounting plate is provided at the end of the connecting shaft 23 away from the fifth helical gear 24. The third mounting plate and the first mounting plate 20 have the same structure, and the fourth mounting plate and the second mounting plate 21 have the same structure. After the third mounting plate and the fourth mounting plate are installed, the installation of the first motor 10 and the connecting shaft 23 is realized.
[0088] The output end of the second motor can be respectively connected to the first winding shaft 7 or the second winding shaft 8 to drive the first winding shaft 7 and the second winding shaft 8 to rotate, thereby realizing the unwinding and winding of the base material 22.
[0089] This embodiment also provides a method for baking a substrate, which uses the above-mentioned substrate baking equipment and includes the following steps:
[0090] Remove the outer packaging of the rolled substrate 22, then fix the rolled substrate 22 on the first coiling shaft 7 at the lower left corner of the baking rack, disassemble the anti-collision film and separator paper on the rolled substrate 22, pass the substrate 22 parallelly through the upper ends of multiple moving screws 4 in sequence, and then fix it on the second coiling shaft 8 at the lower right corner of the baking rack.
[0091] After the substrate 22 is fixed on the second coiling shaft 8, connect the transmission component to the baking rack. The specific steps are as follows: Place the transmission component on the side of the baking rack where the ball screw pair 5 is provided, align the multiple transmission shafts 12 in the transmission component with the corresponding ball screw pair 5, open the solenoid valve corresponding to the first ball screw pair 5 on the right side of the baking rack, and connect the first ball screw pair 5 on the right side with the corresponding transmission shaft 12.
[0092] Connect the second motor to the first coiling shaft 7.
[0093] After the connection between the transmission component and the baking rack is completed and the connection between the second motor and the first coiling shaft 7 is completed, start the second motor to make the first coiling shaft 7 rotate clockwise to unwind the substrate 22. At the same time, start the transmission component to make the first ball screw pair 5 on the right side start to operate, and then make the first moving screw 4 on the right side corresponding to it move upward in the corresponding chute 9 of the first plate body 1.
[0094] When the first moving screw 4 on the right side moves upward to the upper end in the corresponding chute 9, the limit inductor on the first moving screw 4 on the right side will transmit an instruction to the corresponding solenoid valve to make the solenoid valve close the air valve, separate the first ball screw pair 5 on the right side from the corresponding transmission shaft 12, and thus the first ball screw pair 5 on the right side stops operating. As a result, the first moving screw 4 on the right side stops at the upper end of its corresponding chute 9.
[0095] When the first moving screw 4 on the right side moves upward to the upper end in the corresponding chute 9, the limit inductor on the first moving screw 4 on the right side will simultaneously transmit an instruction to the solenoid valve corresponding to the second ball screw pair 5 on the right side to make the solenoid valve open the air valve, so that the second ball screw pair 5 on the right side starts to operate. As a result, the second moving screw 4 on the right side starts to move upward.
[0096] Make all the moving screws 4 stop at the upper ends of their corresponding chutes 9 in sequence, so that the substrate 22 is fully unwound.
[0097] After the substrate 22 is fully unwound, separate the baking rack from the transmission component and separate the second motor from the first coiling shaft 7, and then push the baking rack into the oven to bake the substrate 22. The specific baking parameters are determined according to the properties of different types of substrates 22.
[0098] After the baking of the base material 22 is completed, pull out the baking rack from the oven, connect the baking rack to the transmission assembly again, and connect the second motor to the second winding shaft 8.
[0099] After the connection between the baking rack and the transmission assembly is completed and the connection between the second motor and the second winding shaft 8 is completed, start the transmission assembly to lower the first moving screw rod 4 on the right to reset, and at the same time start the second motor to rotate the second winding shaft 8 in the clockwise direction to wind up the base material 22.
[0100] After the first moving screw rod 4 on the right moves down and resets along the corresponding sliding groove 9 on the first plate body 1, the limit sensor on the first moving screw rod 4 on the right transmits an instruction to the corresponding solenoid valve, causing the solenoid valve to close the air valve, separating the first ball screw pair 5 on the right from the corresponding transmission shaft 12, so that the first ball screw pair 5 on the right stops operating. Thus, the first moving screw rod 4 on the right stops at the bottom of its corresponding sliding groove 9.
[0101] At the same time, when the first moving screw rod 4 on the right moves down and resets along the corresponding sliding groove 9 on the first plate body 1, the limit sensor on the first moving screw rod 4 on the right will simultaneously transmit an instruction to the solenoid valve corresponding to the second ball screw pair 5 on the right, causing the solenoid valve to open the air valve, so that the second ball screw pair 5 on the right starts to operate. Thus, the second moving screw rod 4 on the right starts to move downward until it stops at the bottom of its corresponding sliding groove 9.
[0102] Successively lower and reset all the moving screw rods 4, so that the base material 22 is wound onto the second winding shaft 8, and the rolled base material 22 is taken off the second winding shaft 8 for packaging and boxing.
[0103] In the present invention, specific embodiments are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
