Description

Technical Field

[0001] This application relates to the technical field of attachment processing, and in particular to attachment platforms. Background Technology

[0002] With the continuous popularization and upgrading of smart devices, flat panel display technology and touch technology have developed rapidly. In the manufacturing process of electronic products such as flat panel display devices and touch panels, bonding technology is used extensively to bond two materials together. Circuit boards also require bonding technology in their processing and manufacturing. By attaching auxiliary materials such as copper foil to the circuit board, the function of the circuit board is improved. The copper foil can play an insulating role for the circuit board, thereby forming a corresponding protective layer on the surface of the circuit board and improving the service life of the circuit board.

[0003] Before copper foil is applied, the circuit board needs to be fixed on the application platform, and then the copper foil is applied to the product surface. The application process requires the product to be in a stable state. Existing application platforms fix the circuit board by mechanical clamping. However, for some circuit boards that are not pressure resistant, such as flexible circuit boards like FPCs, mechanical clamping can easily damage the circuit board and reduce its lifespan. Therefore, further optimization is needed. Summary of the Invention

[0004] To reduce the possibility of damage during circuit board mounting, this application provides an attachment platform.

[0005] The attachment platform provided in this application adopts the following technical solution:

[0006] The attachment platform includes a first support platform and a second support platform located on one side of the first support platform. A mounting base is installed at the bottom of the first support platform, and the mounting base is provided with an adjustment component for driving the first support platform to rise and fall. A vacuum groove for adsorbing circuit boards is opened on the upper surface of the first support platform. The vacuum groove is an annular groove. A connecting hole is opened on the side wall of the first support platform, which is connected to the vacuum groove. The connecting hole is used to connect an external vacuum pumping device.

[0007] By adopting the above technical solution, the vacuum tank provides a mounting platform for the circuit board by setting up the first and second support platforms. When the contact surfaces of the circuit board are not on the same horizontal plane or when special flexible circuit boards such as FPCs need to be placed, the height difference between the first and second support platforms can be adjusted in advance by adjusting the components, so that the first and second support platforms can adapt to the placement of different parts of the circuit board product, allowing the circuit board to better fit the upper surfaces of the first and second support platforms. After the height adjustment is completed, the circuit board is placed on the first and second support platforms, and then the vacuum device is activated to force a negative pressure to be formed in the vacuum tank, thereby adsorbing the circuit board onto the upper surface of the first support platform, which has the effect of fixing the circuit board, so as to facilitate the application of auxiliary materials and other processing operations on the circuit board and improve the quality of the application. On the other hand, setting the vacuum tank as an annular tank can increase the adsorption area of ​​the vacuum tank on the circuit board, thereby further improving the adsorption effect of the vacuum device on the circuit board, improving the adsorption stability between the circuit board and the first support platform, and reducing the possibility of damage to the circuit board during fixing.

[0008] Optionally, the top wall of the mounting base has a mounting groove, and a movable seat located above the mounting base is slidably mounted in the mounting groove. The movable seat and the first support platform are fixedly connected to each other by a connecting column. A screw is fixed to the bottom of the movable seat, and a first rotating sleeve is rotatably connected to the side wall of the mounting groove. The first rotating sleeve is sleeved on the screw and threadedly connected to the screw. The adjusting assembly includes a rotating shaft, a first driving bevel gear, and a first driven bevel gear. The rotating shaft is rotatably connected to the side wall of the mounting groove. The first driving bevel gear is coaxially connected to the outer peripheral wall of the rotating shaft. The first driven bevel gear is coaxially fixed to the outer peripheral wall of the first rotating sleeve at the end away from the screw. The first driving bevel gear and the first driven bevel gear mesh and drive each other. One end of the rotating shaft passes through the mounting base and is connected to a wheel for driving the rotating shaft to rotate.

[0009] By adopting the above technical solution, through the setting of the rotating shaft, the first rotating sleeve and the screw, when it is necessary to adjust the height of the first support platform, the rotating shaft is driven to rotate by the rotating wheel, and the rotating sleeve rotates under the meshing transmission of the first driving bevel gear and the first driven bevel gear, which drives the screw to rise or fall, thereby driving the first support platform to rise or fall, improving the convenience of adjusting the height of the first support platform.

[0010] Optionally, the vacuum tank is slidably mounted with an abutment plate adapted to the shape of the vacuum tank. A first compression spring is installed between the vacuum tank and the abutment plate. The first compression spring normally forces the abutment plate to partially protrude from the upper surface of the first support platform. The bottom of the vacuum tank has a first air passage connected to a connecting hole, and the side wall of the vacuum tank has a second air passage penetrating the upper surface of the first support platform. The abutment plate has a third air passage. The third air passage is normally offset from the second air passage. When the upper surface of the abutment plate moves to be flush with the upper surface of the first support platform, the two ends of the third air passage are respectively connected to the first air passage and the second air passage.

[0011] By adopting the above technical solution, the abutment plate, under the action of the first compression spring, protrudes from the upper surface of the first support platform. When the circuit board is placed on the upper surface of the first support platform, it first contacts the abutment plate. At this time, the vacuum device is activated to evacuate the vacuum tank. The third air channel and the second air channel are misaligned to form a closed space. The vacuum device can pull the abutment plate and force it to move towards the bottom of the vacuum tank. When the upper surface of the abutment plate moves to be flush with the upper surface of the first support platform, the two ends of the third air channel are connected to the first air channel and the second air channel respectively. At this time, the circuit board is against the upper surface of the first support platform, and the vacuum device can adsorb the circuit board onto the upper surface of the first support platform. After the circuit board auxiliary material is attached, the vacuum device is turned off to adsorb the circuit board. The abutment plate can protrude from the upper surface of the first support platform under the elastic force of the first compression spring, thereby pushing the circuit board out and reducing the possibility that the adhesion between the circuit board and the first support platform is too strong and it is difficult to remove the circuit board.

[0012] Optionally, the upper surface of the first support platform has two limiting grooves located on both sides of the circuit board. Each limiting groove is slidably fitted with a limiting block. A second compression spring is installed between the limiting block and the limiting groove. The second compression spring normally forces the limiting block to protrude from the upper surface of the first support platform. A connecting rope is connected between the abutting plate and the limiting block. When the abutting plate protrudes from the upper surface of the first support platform, the connecting rope forces the limiting block to move into the limiting groove.

[0013] By adopting the above technical solution and setting the limiting block, when the vacuum device adsorbs the circuit board onto the upper surface of the first support platform, it can drive the abutment plate to move into the vacuum groove. At this time, the connecting rope is released and pulls the limiting block. The limiting block can protrude from the upper surface of the first support platform under the action of the second compression spring. The two limiting blocks can be respectively limited to both sides of the circuit board, reducing the possibility of the circuit board sliding horizontally when the vacuum device adsorbs the circuit board, and further improving the connection between the circuit board and the first support platform.

[0014] Optionally, the first support platform includes a main support platform and a secondary support platform slidably installed on one side of the main support platform. The two limiting blocks are slidably installed on the main support platform and the secondary support platform, respectively. A telescopic rod is installed between the two limiting blocks. The movable seat is provided with a moving mechanism that drives the main support platform and the secondary support platform to move closer to each other or further away from each other.

[0015] By adopting the above technical solution and setting up the moving mechanism, when it is necessary to perform adsorption operations on circuit boards of different sizes, the moving mechanism can force the main support platform and the secondary support platform to move closer to or further away from each other, thereby adjusting the distance between the two limiting blocks to adapt to the limiting effect of circuit boards of different sizes and improving the applicability of the overall structure.

[0016] Optionally, the movable seat includes a fixed plate and an adjusting plate slidably mounted on one side of the fixed plate. The main support platform is fixedly connected to the fixed plate, and the secondary support platform is fixedly connected to the adjusting plate. An adjusting groove is provided on the side wall of the adjusting plate near the fixed plate. The moving mechanism includes a lead screw, a rotating rod, a second driving bevel gear, and a second driven bevel gear. One end of the lead screw is rotatably connected to the side wall of the fixed plate near the adjusting plate, and the other end is inserted into the adjusting groove and threadedly connected to the adjusting groove. One end of the rotating rod is rotatably connected to the side wall of the fixed plate, and the other end of the rotating rod extends into the mounting groove. The second driving bevel gear is coaxially mounted on the outer peripheral wall of one end of the rotating rod, and the second driven bevel gear is coaxially fixed to the outer peripheral wall of the lead screw. The second driving bevel gear and the second driven bevel gear mesh and transmit power. The rotating rod is provided with a rotating assembly for driving the rotating rod to rotate.

[0017] By adopting the above technical solution, and through the setting of the lead screw and the rotating rod, when it is necessary to adjust the distance between the two limit blocks, the rotating component drives the rotating rod to rotate. The lead screw can rotate under the meshing transmission of the second active bevel gear and the second driven bevel gear, so that the auxiliary support platform moves closer to or away from the main support platform under the drive of the lead screw, thereby adjusting the distance between the two limit blocks.

[0018] Optionally, the rotating assembly includes a second rotating sleeve, a third driving bevel gear, and a third driven bevel gear. The second rotating sleeve is slidably sleeved on the rotating rod. The third driving bevel gear is coaxially mounted on the rotating shaft. The third driven bevel gear is coaxially mounted on the outer peripheral wall of the second rotating sleeve at the end away from the rotating rod. The third driving bevel gear and the third driven bevel gear mesh and transmit power. The rotating shaft is provided with a control component for driving the first rotating sleeve and the second rotating sleeve to rotate respectively.

[0019] By adopting the above technical solution, the second rotating sleeve can slide along the rotating rod when the moving seat rises or falls to adapt to the height change of the moving seat; the third driving bevel gear is coaxially installed on the rotating shaft, and rotating the rotating shaft can force the third driving bevel gear to mesh with the third driven bevel gear, thereby driving the second rotating sleeve and the rotating rod to rotate, and thus causing the two limiting blocks to move closer or further apart.

[0020] Optionally, the rotating shaft is rotatably and slidably mounted on the side wall of the mounting groove. A connecting frame is fixed to the side wall of the mounting groove. The connecting frame is rotatably connected to two connecting sleeves. The first and third active bevel gears are coaxially fixed to the outer peripheral walls of the two connecting sleeves. The rotating shaft passes through the two connecting sleeves. Each connecting sleeve has a force-applying groove on its inner peripheral wall. The control component includes a force-applying block for engaging the force-applying groove. The force-applying block is fixedly mounted on the outer peripheral wall of the rotating shaft.

[0021] By adopting the above technical solution, and through the setting of the force-applying block and the force-applying groove, when it is necessary to adjust the height of the first support platform, pulling the rotating shaft causes the rotating shaft to slide along the connecting sleeve. When the force-applying block moves and engages with the force-applying groove of the first active bevel gear connecting sleeve, rotating the rotating shaft can adjust the height of the first support platform. When it is necessary to adjust the distance between the two limit blocks, pulling the rotating shaft causes the force-applying block to move and engage with the force-applying groove of the third active bevel gear connecting sleeve. Rotating the rotating shaft can adjust the distance between the two limit blocks. This improves the speed of switching between the two adjustment methods and increases work efficiency.

[0022] Optionally, two spaced-apart first magnets are fixed to the sidewalls of the mounting groove, the distance between the two first magnets being equal to the distance between the two connecting sleeves. A second magnet for attracting the first magnets is fixed to the outer peripheral wall of the rotating shaft. When the first magnet and the second magnet are attracted, the force-applying block is engaged in the force-applying groove of the first active bevel gear connecting sleeve or in the force-applying groove of the third active bevel gear connecting sleeve.

[0023] By adopting the above technical solution, the first magnet and the second magnet are used to pull the rotating shaft to force the force-applying block to move and engage with the force-applying groove of the first active bevel gear connecting sleeve or the third active bevel gear connecting sleeve. At this time, the first magnet and the second magnet can attract each other, so that the force-applying block can disengage from the force-applying groove when the operator rotates the rotating shaft. When it is not necessary to adjust the height of the first support platform or the distance between the two limit blocks, it is only necessary to push the rotating shaft to force the first magnet and the second magnet to separate, so that the force-applying block can be moved out of the force-applying groove, thereby improving the operational convenience of the overall structure.

[0024] Optionally, an installation sleeve is fixedly installed on the side wall of the installation groove, and the end of the rotating shaft away from the rotating wheel is inserted into the installation sleeve. The rotating shaft slides and rotates to be connected to the installation sleeve. A third compression spring is installed between the installation sleeve and the rotating shaft. The third compression spring normally forces the force-applying block to disengage from the force-applying groove.

[0025] By adopting the above technical solution and setting the third compression spring, the force-applying block is normally disengaged from the force-applying groove, the connection between the rotating shaft and the first or third active bevel gear is released, the possibility of the rotating shaft rotating due to accidental contact with the rotating wheel by external personnel is reduced, and the stability of the first support platform after height adjustment or the stability of the distance between the two limit blocks after adjustment is improved.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a vacuum tank, the first and second support platforms provide attachment platforms for placing the circuit board. When the contact surfaces of the circuit board are not on the same horizontal plane, or when special flexible circuit boards such as FPCs need to be placed, the height difference between the first and second support platforms can be adjusted in advance by adjusting the components. This allows the first and second support platforms to adapt to the placement of different parts of the circuit board product, enabling the circuit board to better adhere to the upper surfaces of the first and second support platforms. After the height adjustment is completed, the circuit board is placed on the first and second support platforms, and then the vacuum device is activated to force a negative pressure to form in the vacuum tank, thereby adsorbing the circuit board onto the upper surface of the first support platform, which has the effect of fixing the circuit board. This facilitates the attachment of auxiliary materials and other processing operations on the circuit board and improves the quality of the attachment. On the other hand, setting the vacuum tank as an annular tank can increase the adsorption area of ​​the vacuum tank on the circuit board, thereby further improving the adsorption effect of the vacuum device on the circuit board, improving the adsorption stability between the circuit board and the first support platform, and reducing the possibility of damage to the circuit board during fixing.

[0028] 2. With the abutment plate in place, the abutment plate normally protrudes from the upper surface of the first support platform under the action of the first compression spring. When the circuit board is placed on the upper surface of the first support platform, it first contacts the abutment plate. At this time, the vacuum device is activated to evacuate the vacuum tank. At this time, the third air channel and the second air channel are staggered to form a closed space. The vacuum device can pull the abutment plate and force it to move towards the bottom of the vacuum tank. When the upper surface of the abutment plate moves to be flush with the upper surface of the first support platform, the two ends of the third air channel are connected to the first air channel and the second air channel respectively. At this time, the circuit board is against the upper surface of the first support platform, and the vacuum device can adsorb the circuit board onto the upper surface of the first support platform. After the circuit board auxiliary material is attached, the vacuum device is turned off to adsorb the circuit board. The abutment plate can protrude from the upper surface of the first support platform under the elastic force of the first compression spring, thereby pushing the circuit board out and reducing the possibility that the adhesion between the circuit board and the first support platform is too strong and it is difficult to remove the circuit board.

[0029] 3. By setting the limiting blocks, after the vacuuming device adsorbs the circuit board onto the upper surface of the first support platform, it can drive the abutment plate to move into the vacuum groove. At this time, the connecting rope is released and pulls the limiting blocks. Under the action of the second compression spring, the limiting blocks can protrude from the upper surface of the first support platform. The two limiting blocks can be respectively limited to both sides of the circuit board, reducing the possibility of the circuit board sliding horizontally when the vacuuming device adsorbs the circuit board, and further improving the connection between the circuit board and the first support platform.

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0041] Example 1:

[0042] This application discloses an attachment platform.

[0043] Reference Figure 1 , Figure 2The attachment platform includes a first support platform 1 and a second support platform 2 located on one side of the first support platform 1. In this embodiment, the bottom of the first support platform 1 is provided with a mounting base 3, and the first support platform 1 is supported on the ground by the mounting base 3. The bottom of the second support platform 2 is provided with a bracket 21, and the second support platform 2 is supported on the ground by the bracket 21. The upper surface of the first support platform 1 and the upper surface of the second support platform 2 are used together to place the circuit board to be attached.

[0044] Reference Figure 1 , Figure 2 The upper surface of the first support platform 1 is provided with a vacuum groove 11 for adsorbing the circuit board. In this embodiment, the vacuum groove 11 is set as a rectangular ring structure, and there are two vacuum grooves 11 distributed at intervals on the upper surface of the first support platform 1. The side wall of the first support platform 1 is provided with a connecting hole 12 communicating with the vacuum groove 11. There are two connecting holes 12, and the two connecting holes 12 are respectively set one-to-one with the two vacuum grooves 11. The slot of the connecting hole 12 is used to connect an external vacuum pumping device (not shown in the figure). With this design, after the circuit board to be processed is placed on the upper surface of the first support platform 1 and the upper surface of the second support platform 2, the vacuum pumping device is activated to remove the air in the vacuum groove 11, forcing the vacuum groove 11 to form a negative pressure, thereby adsorbing and fixing the circuit board to the upper surface of the first support platform 1, so as to facilitate the processing operations such as attaching auxiliary materials to the circuit board.

[0045] Reference Figure 2 , Figure 3 The top wall of the mounting base 3 has a mounting groove 31, on which a movable seat 5 located above the mounting base 3 is slidably mounted. Multiple guide sleeves 38 are fixedly mounted on the bottom wall of the mounting groove 31. Multiple guide posts 55 are fixedly mounted on the plate surface of the movable seat 5 near the mounting groove 31. All guide posts 55 are arranged one-to-one with all guide sleeves 38, and each guide post 55 is slidably inserted into the corresponding guide sleeve 38. The movable seat 5 is slidably mounted on the guide sleeve 38 through the guide posts 55. Multiple connecting posts 51 are fixedly mounted on the upper surface of the movable seat 5. The free ends of all connecting posts 51 are fixedly connected to the lower surface of the first support platform 1. The first support platform 1 is slidably mounted on the mounting base 3 through the connecting posts 51 and the movable seat 5. The mounting base 3 is provided with an adjustment component 4 for driving the first support platform 1 to rise and fall.

[0046] By adjusting the height of the first support platform 1 using the adjusting component 4, the height difference between the first support platform 1 and the second support platform 2 can be adjusted. When the contact surfaces of different parts of the circuit board are not on the same horizontal plane, or when the attachment platform is used to place special flexible circuit boards such as FPCs, the height difference between the first support platform 1 and the second support platform 2 can be adjusted by the adjusting component 4, so that the attachment platform can adapt to the placement of different circuit boards, improve the adhesion between the circuit board and the upper surface of the first support platform 1 and the upper surface of the second support platform 2, so as to facilitate the attachment of auxiliary materials to the circuit board and improve the quality of the attached auxiliary materials.

[0047] Reference Figure 3 A connecting frame 33 is fixedly installed on the side wall of the mounting slot 31. A first rotating sleeve 32 is rotatably installed on the connecting frame 33. A screw 52 is fixedly installed on the bottom of the movable seat 5. The screw 52 is inserted into the first rotating sleeve 32 and threadedly connected to the first rotating sleeve 32.

[0048] Reference Figure 3 The adjustment assembly 4 includes a rotating shaft 41, a first driving bevel gear 42, and a first driven bevel gear 43. The rotating shaft 41 is horizontally arranged and rotatably connected to the side wall of the mounting groove 31. One end of the rotating shaft 41 passes through the side wall of the mounting base 3 and is connected to a wheel 411 for driving the rotating shaft 41 to rotate. The first driving bevel gear 42 is coaxially connected to the outer peripheral wall of the rotating shaft 41, and the first driven bevel gear 43 is coaxially fixed to the outer peripheral wall of the end of the first rotating sleeve 32 away from the screw 52. The first driving bevel gear 42 and the first driven bevel gear 43 mesh and transmit power. With this design, the rotating shaft 41 is driven to rotate by the wheel 411, which can force the first rotating sleeve 32 to rotate, thereby forcing the screw 52 to rise and fall, thereby adjusting the height of the first support platform 1 and improving the convenience of adjusting the height of the first support platform 1.

[0049] Reference Figure 1 , Figure 2 The upper surface of the bracket 21 is provided with a fixing groove 211. The second support platform 2 is installed in the fixing groove 211. The groove opening of the fixing groove 211 is detachably installed with a clamping block 212. In this embodiment, there are two clamping blocks 212 and they are symmetrically distributed on both sides of the second support platform 2. The second support platform 2 is detachably installed on the bracket 21 through the clamping blocks 212.

[0050] Reference Figure 1 , Figure 2A strip plate 22 is installed on the lower surface of the bracket 21. The strip plate 22 is located on the side of the second support platform 2 away from the first support platform 1. A support plate 23 for supporting the circuit board is installed on the upper surface of the strip plate 22. Multiple threaded holes 221 are opened on the surface of the strip plate 22. All threaded holes 221 are spaced apart along the length of the strip plate 22. A first bolt 231 is installed on the support plate 23. The first bolt 231 passes through the support plate 23 and is threaded into the threaded hole 221.

[0051] Reference Figure 1 , Figure 2 The surface of the bracket 21 is provided with a strip groove 213. The length direction of the strip groove 213 is perpendicular to the length direction of the strip plate 22. A second bolt 214 is installed in the strip groove 213. The second bolt 214 passes through the strip groove 213 and is threaded into the threaded hole 221. With this design, when the circuit board is long, the support plate 23 can play a role in supporting the circuit board. The position between the support plate 23 and the second support platform 2 can be adjusted by the strip plate 22 to adapt to support circuit boards of different lengths and improve the applicability of the overall structure.

[0052] The implementation principle of Embodiment 1 of this application is as follows: Based on the actual situation of the contact surface of the circuit board to be processed, the height difference between the first support platform 1 and the second support platform 2 is adjusted by adjusting component 4, which can improve the fit between the circuit board and the first support platform 1 and the second support platform 2. Then, the distance between the tray 23 and the second support platform 2 is adjusted according to the actual size of the circuit board, so that the tray 23 can better support the circuit board and improve the overall structure's support effect on the circuit board. Then, the circuit board is placed on the upper surface of the first support platform 1 and the upper surface of the second support platform 2, and the vacuum device is activated to vacuum the vacuum tank 11. The circuit board can be adsorbed onto the upper surface of the first support platform 1 under the action of external pressure, thereby fixing the circuit board to the first support platform 1, so as to facilitate the processing of the circuit board and improve the processing quality of the circuit board.

[0053] Example 2:

[0054] This application discloses an attachment platform.

[0055] Reference Figure 4 , Figure 5 The difference between the attachment platform disclosed in this application embodiment and that in embodiment 1 is as follows:

[0056] The sidewall of the vacuum tank 11 is slidably fitted with an abutment plate 13. In this embodiment, the shape of the abutment plate 13 is a rectangular ring plate that matches the shape of the vacuum tank 11. The bottom of the vacuum tank 11 is provided with a plurality of first clearance grooves 113. All the first clearance grooves 113 are spaced apart along the bottom of the vacuum tank 11. A first compression spring 14 is installed between the bottom of each first clearance groove 113 and the abutment plate 13. The first compression spring 14 normally forces the abutment plate 13 to protrude from the upper surface of the first support platform 1.

[0057] Reference Figure 4 , Figure 5 The vacuum tank 11 has a first air passage 111 at its bottom, which is connected to the connecting hole 12. In this embodiment, multiple first air passages 111 are provided and spaced apart along the bottom of the vacuum tank 11. The lower surface of the abutment plate 13 has a third air passage 131 that penetrates the side wall of the abutment plate 13. Multiple third air passages 131 are provided and are arranged one-to-one with the first air passages 111. The side wall of the vacuum tank 11 has a second air passage 112 that penetrates the upper surface of the first support platform 1. Multiple second air passages 112 are provided and are arranged one-to-one with the first air passages 111. When the lower surface of the abutment plate 13 abuts against the bottom of the vacuum tank 11, the upper surface of the abutment plate 13 is flush with the upper surface of the first support platform 1, and the first air passages 111, the second air passages 112, and the third air passages 131 are interconnected.

[0058] After the circuit board is placed on the upper surface of the abutment plate 13, the vacuum device is activated. The vacuum device can pump out the air in the vacuum tank 11 and force the lower surface of the abutment plate 13 to abut the bottom of the vacuum tank 11. At this time, the first air channel 111, the second air channel 112 and the third air channel 131 are connected to each other. The vacuum device can adsorb the circuit board onto the upper surface of the first support platform 1 through the first air channel 111, the second air channel 112 and the third air channel 131. When the vacuum device is turned off, the abutment plate 13 can push the circuit board upward under the action of the first compression spring 14, reducing the possibility that the adhesion between the circuit board and the first support platform 1 is too strong and it is inconvenient to remove the circuit board.

[0059] Reference Figure 5 , Figure 6 The first support platform 1 includes a main support platform 18 and a secondary support platform 19. The secondary support platform 19 is located on one side of the main support platform 18. A first guide rod 181 is fixedly installed on the side wall of the main support platform 18 near the secondary support platform 19. A first guide groove 191 is opened on the side wall of the secondary support platform 19 near the main support platform 18. The first guide rod 181 is slidably inserted into the first guide groove 191. The secondary support platform 19 is slidably installed on the main support platform 18 through the first guide rod 181.

The two limiting grooves 15 are symmetrically distributed on both sides of the width direction of the circuit board. Each limiting groove 15 is slidably installed with a limiting block 16. A second compression spring 17 is installed between the bottom of the limiting groove 15 and the limiting block 16. The second compression spring 17 normally forces the limiting block 16 to protrude from the upper surface of the main support platform 18 or the upper surface of the secondary support platform 19.

[0061] Reference Figure 4 A connecting rope 132 is connected between the abutment plate 13 and the limiting block 16 of the main support platform 18. One end of the connecting rope 132 is fixedly connected to the lower surface of the abutment plate 13, and the other end passes through the side wall of the first clearance groove 113, then extends out from the bottom wall of the limiting groove 15 of the main support platform 18 and is fixedly connected to the bottom wall of the limiting block 16. When the abutment plate 13 protrudes from the upper surface of the first support platform 1, the connecting rope 132 pulls the limiting block 16 and forces the limiting block 16 to move into the limiting groove 15. With this design, the two limiting blocks 16 can limit the circuit board and reduce the possibility of the circuit board sliding.

[0062] Reference Figure 6 , Figure 7 The two limiting grooves 15 are provided with second clearance grooves 151 on their sidewalls that are close to each other. The two second clearance grooves 151 are connected to each other and are staggered with the connecting rope 132. A telescopic rod 161 is installed between the two limiting blocks 16. The movable seat 5 is provided with a moving mechanism 6 that drives the secondary support platform 19 to move closer to or away from the main support platform 18. With this design, the distance between the main support platform 18 and the secondary support platform 19 can be adjusted by the moving mechanism 6, thereby adjusting the distance between the two limiting blocks 16, so that the two limiting blocks 16 can adapt to limiting circuit boards of different sizes and improve the adaptability of the overall structure.

[0063] Reference Figure 6 , Figure 8 The movable seat 5 includes a fixed plate 53 and an adjusting plate 54. The adjusting plate 54 is located on one side of the fixed plate 53. A second guide rod 531 is fixedly installed on the side wall of the fixed plate 53 near the adjusting plate 54. A second guide groove 542 is opened on the side wall of the adjusting plate 54 near the fixed plate 53. The adjusting plate 54 is slidably installed on the fixed plate 53 through the second guide rod 531. The main support platform 18 is fixedly connected to the fixed plate 53 through the connecting column 51. The auxiliary support platform 19 is fixedly connected to the adjusting plate 54 through the connecting column 51. A third clearance groove 543 is opened on the side wall of the adjusting plate 54 near the fixed plate 53, penetrating the surface of the adjusting plate 54. An adjusting groove 541 is opened on the side wall of the third clearance groove 543 away from the fixed plate 53.

[0064] Reference Figure 6 , Figure 8The moving mechanism 6 includes a lead screw 61, a rotating rod 62, a second driving bevel gear 63, and a second driven bevel gear 64. One end of the lead screw 61 is rotatably mounted on the side wall of the fixed plate 53 near the adjusting plate 54, and the other end of the lead screw 61 is inserted into the adjusting groove 541 and threadedly connected to the adjusting groove 541. One end of the rotating rod 62 is rotatably connected to the side wall of the fixed plate 53 near the adjusting plate 54, and the other end extends into the mounting groove 31. The second driving bevel gear 63 is located in the third clearance groove 543 and is coaxially mounted on the outer peripheral wall of one end of the rotating rod 62. The second driven bevel gear 64 is coaxially fixed to the outer peripheral wall of the lead screw 61. The second driving bevel gear 63 and the second driven bevel gear 64 mesh and transmit power. The rotating rod 62 is provided with a rotating assembly 7 for driving the rotating rod 62 to rotate.

[0065] Reference Figure 6 , Figure 8 The rotating assembly 7 includes a second rotating sleeve 71, a third driving bevel gear 72, and a third driven bevel gear 73. The second rotating sleeve is connected to the rotating rod 62. The third driving bevel gear 72 is coaxially mounted on the rotating shaft 41. The third driven bevel gear 73 is coaxially mounted on the outer peripheral wall of the end of the second rotating sleeve 71 away from the rotating rod 62. The third driving bevel gear 72 and the third driven bevel gear 73 mesh and drive each other. With this design, when the rotating shaft 41 is rotated, the lead screw 61 can rotate in sequence under the meshing drive of the third driving bevel gear 72 and the third driven bevel gear 73, and under the meshing drive of the second driving bevel gear 63 and the second driven bevel gear 64, thereby driving the adjusting plate 54 to move closer to or away from the fixed plate 53, and thus causing the secondary support platform 19 to move closer to or away from the main support platform 18. The distance between the two limiting blocks 16 is adjusted to limit circuit boards of different sizes.

[0066] Reference Figure 6 , Figure 9 The mounting sleeve 36 is fixedly installed on the side wall of the mounting groove 31. The end of the rotating shaft 41 away from the rotating wheel 411 is slidably inserted into the mounting sleeve 36. The rotating shaft 41 is slidably and rotatably installed on the mounting sleeve 36. The connecting frame 33 is rotatably installed with two connecting sleeves 34. Each connecting sleeve 34 has a force groove 341 on its inner peripheral wall for forcing the connecting sleeve 34 to rotate. In this embodiment, the first active bevel gear 42 and the third active bevel gear 72 are coaxially fixed to the outer peripheral walls of the two connecting sleeves 34 respectively. The rotating shaft 41 passes through the two connecting sleeves 34. The rotating shaft 41 is provided with a control component for driving the two connecting sleeves 34 to rotate respectively.

[0067] Reference Figure 6 , Figure 9In this embodiment, the control component is set as a force-applying block 412, which is fixedly installed on the outer peripheral wall of the rotating shaft 41 and the shape of the force-applying block 412 is adapted to the shape of the force-applying groove 341. With this design, when it is necessary to adjust the lifting of the first support platform 1, the rotating shaft 41 is pulled to force the force-applying block 412 to move to the connecting sleeve 34 of the first active bevel gear 42, forcing the force-applying block 412 to engage with the force-applying groove 341 of the connecting sleeve 34 of the first active bevel gear 42. Rotating the rotating shaft 41 can drive the first support platform 1 to lift. When the distance between the two limit blocks 16 is needed, the rotating shaft 41 is pulled again to engage the force-applying block 412 with the force-applying groove 341 of the connecting sleeve 34 of the third active bevel gear 72. Rotating the rotating shaft 41 can control the sliding of the adjusting plate 54, thereby adjusting the distance between the two limit blocks 16 and improving the switching efficiency of the two adjustment methods.

[0068] Reference Figure 6 , Figure 9 A third compression spring 37 is installed between the mounting sleeve 36 and the rotating shaft 41. The third compression spring 37 normally forces the force application block 412 to disengage from the force application groove 341 and be located on the side of the first active bevel gear 42 away from the third active bevel gear 72.

[0069] Reference Figure 6 , Figure 9 The inner circumferential wall of the mounting sleeve 36 has two spaced-apart first annular grooves, and a first magnet 35 is bonded and fixed in each first annular groove. In this embodiment, the distance between the two first magnets 35 is equal to the distance between the two connecting sleeves 34. The outer circumferential wall of the rotating shaft 41 has a second annular groove, and a second magnet 413 is bonded and fixed in the second annular groove. When the rotating shaft 41 is pulled to slide and force the first magnet 35 and the second magnet 413 to attract each other, the force-applying block 412 engages with the force-applying groove 341 of the first active bevel gear 42 connecting sleeve 34 or with the third active bevel gear 72 connecting sleeve 34. In this embodiment, the magnetic force between the first magnet 35 and the second magnet 413 is greater than the elastic force of the third compression spring 37. With this design, when the force block 412 is engaged in the force groove 341 of the connecting sleeve 34 of the first active bevel gear 42 or the connecting sleeve 34 of the third active bevel gear 72, the magnetic force is greater than the elastic force of the third compression spring 37, which can keep the force block 412 in the force groove 341, so that the operator can control the rotation of the first active bevel gear 42 or the rotation of the third active bevel gear 72 through the rotating shaft 41.

[0070] The implementation principle of Embodiment 2 of this application is as follows: The height of the first support platform 1 is adjusted according to the flatness of the contact surface of the circuit board to be processed. The rotating shaft 41 is pulled to force the force-applying block 412 of the rotating shaft 41 to engage with the force-applying groove 341 of the connecting sleeve 34 of the first active bevel gear 42. Then, rotating the rotating shaft 41 adjusts the height difference between the first support platform 1 and the second support platform 2 to adapt to the contact surface of the circuit board, improving the fit between the circuit board and the upper surface of the first support platform 1 and the upper surface of the second support platform 2. After the height of the first support platform 1 is adjusted, the rotating shaft 41 is pulled further, forcing the force-applying block 412 of the rotating shaft 41 to engage with the force-applying groove 341 of the connecting sleeve 34 of the third active bevel gear 72. Rotating the rotating shaft 41 adjusts the distance between the two limiting blocks 16, allowing the two limiting blocks 16 to be positioned on both sides of the circuit board. After adjustment, the rotating shaft 41 is pushed to force the force-applying block 412 to disengage from the force-applying groove. 341. Then, after placing the circuit board to be processed on the surface of the first support platform 1 and the second support platform 2, the vacuum device is activated to vacuum the vacuum tank 11. The external pressure can attract the abutment plate 13 towards the bottom of the vacuum tank 11. When the lower surface of the abutment plate 13 moves to fit against the bottom of the vacuum tank 11, the circuit board can fit against the surface of the first support platform 1 and the surface of the second support platform 2. At this time, the two limiting blocks 16 can protrude outward under the action of the second compression spring 17 and be limited to both sides of the circuit board, reducing the possibility of the circuit board slipping. At the same time, the first air channel 111, the second air channel 112 and the third air channel 131 are interconnected, so that the vacuum device can attract the circuit board and force the circuit board to fit tightly against the upper surface of the first support platform 1, improving the connection between the circuit board and the first support platform 1, so as to facilitate the subsequent processing of the circuit board and improve the processing quality of the circuit board.

[0071] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
