Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing and processing technology, specifically to a device for improving the production utilization rate of liquid crystal display circuit boards. Background Technology

[0002] In the production process of LCD displays, PCB circuit boards require drilling, which involves drilling the required holes into the board material to facilitate the connection between subsequent layers and the future soldering of components. Drilling holes also serve as positioning or alignment holes for subsequent circuit board processing, and the circuit board is first fixed in place before drilling.

[0003] The uptime in the circuit board production process refers to the load time minus the time for placing and removing the circuit board and the time for drilling. The uptime rate is the ratio of uptime to the overall work load time. Therefore, to increase the uptime rate in the circuit board production process, it is necessary to increase the uptime. However, the following problems exist in the current process of drilling circuit boards: 1. When installing circuit boards for drilling, the position of the circuit board is offset and the clamping limit of the circuit board is not stable. Therefore, when drilling, it is necessary to adjust the position of some circuit boards to ensure their clamping stability. At the same time, a lot of time is spent in placing and removing the circuit boards, which reduces the uptime and thus reduces the production uptime rate.

[0004] 2. During drilling operations, after the circuit board is placed, drilling is performed on it using external drilling equipment. After drilling is completed, the circuit board is removed and an unprocessed circuit board is placed. Therefore, the external drilling equipment is not working during this process. After the unprocessed circuit board is placed, the external drilling equipment re-enters the working state to perform drilling operations, which increases the overall drilling time and reduces the uptime and uptime. Summary of the Invention

[0005] Therefore, it is necessary to provide a production capacity improvement device for liquid crystal display circuit boards, which aims to solve the problems of the prior art.

[0006] On one hand, a production utilization rate improvement device for liquid crystal display circuit boards includes: a circular plate, the circular plate being fixedly disposed on the upper surface of four supports, and four sets of circumferentially evenly distributed plate groups being fixedly disposed on the upper surface of the circular plate, each plate group including four right-angled plates, and an annular mounting plate being fixedly disposed on the upper surface of the four right-angled plates.

[0007] The mounting plate has four sets of circumferentially evenly distributed clamping mechanisms on its upper surface. These four sets of clamping mechanisms work together to clamp and fix the placed circuit board.

[0008] The drilling mechanism includes a rotating shaft rotatably mounted on the upper surface of the circular plate, which is connected to an external motor. The rotating shaft is equipped with a drilling mechanism for drilling holes in the circuit board.

[0009] The clamping mechanism includes a rectangular plate. Taking the clamping mechanism on the front side of the circular plate at the front as an example, the upper end face of the mounting plate at the front is fixedly provided with a rectangular plate. Two symmetrical mounting vertical plates are fixedly provided on the upper end face of the rectangular plate. An L-shaped clamping strip is rotatably installed between the two mounting vertical plates. A pressing plate is rotatably provided on the rear part of the clamping strip. A clamping group is provided on the front part of the clamping strip for driving the clamping strip to drive the pressing plate to clamp the circuit board.

[0010] According to an advantageous embodiment, the clamping assembly includes forward-moving columns. Two left-right symmetrical forward-moving columns are slidably mounted on the front end face of the mounting plate. A limit plate is fixedly mounted on the front end face of the two forward-moving columns. A limit groove for limiting and controlling the front end portion of the clamping strip is provided on the limit plate. A first spring corresponding to each forward-moving column is provided between the limit plate and the mounting plate. A trapezoidal plate is fixedly mounted on the lower end face of the limit plate. The rear side of the trapezoidal plate is inclined. A through groove running from top to bottom is provided on the upper end face of the mounting plate. A mating top plate is slidably mounted in the through groove. An inclined plate that mates with the trapezoidal plate is fixedly mounted on the lower end portion of the mating top plate.

[0011] According to an advantageous embodiment, the upper end face of the mounting plate is provided with an adjustment component for adjusting the position of the circuit board. The adjustment component includes four axially evenly distributed adjustment groups, each adjustment group including a slider groove. The upper end face of the mounting plate has two mutually symmetrical slider grooves. A right-angled trapezoidal adjustment plate is slidably arranged in the two slider grooves through a sliding block. The upper side of the end face of the adjustment plate that contacts the circuit board is an inclined surface. Two mutually symmetrical second springs are fixedly arranged between the adjustment plate and the rectangular plate. An L-shaped plate is fixedly arranged on the right end face of the left rectangular plate and the rear end face of the front rectangular plate. The spring constant of the second springs on the left rectangular plate and the front rectangular plate is smaller than that of the second springs on the rear rectangular plate and the right rectangular plate.

[0012] According to an advantageous embodiment, the mounting plate is provided with a release group for quick contact and simultaneous removal of the circuit board from the clamping state. The release group includes circular grooves. The upper end face of the mounting plate has four circular grooves arranged in a matrix. Circular columns are slidably disposed in the circular grooves. A circular lifting plate is fixedly disposed on the upper end face of the circular column. A connecting plate is fixedly disposed on the lower end face of the circular column. A first cylinder corresponding to the connecting plate is fixedly disposed on the lower end face of the mounting plate. A control column fixedly connected to the corresponding mating top plate is fixedly disposed between two adjacent circular columns.

[0013] According to an advantageous embodiment, the drilling mechanism includes a vertical groove, the rotating shaft has a vertical groove, a placement plate is slidably disposed in the vertical groove via a vertical block, the lower end of the placement plate is provided with a drilling component for drilling the circuit board, and a driving component for intermittently moving the drilling component is provided on both the placement plate and the rotating shaft.

[0014] According to an advantageous embodiment, the drilling component includes a square groove, the front end face of the placement plate is provided with a square groove, a transverse plate is slidably disposed in the square groove by an electric slider one, a transverse groove is provided on the lower end face of the transverse plate, and an external drilling device is slidably disposed in the transverse groove by an electric slider two.

[0015] According to an advantageous embodiment, the driving component includes a transition plate, the transition plate is fixedly mounted on the circumferential surface of the rotating shaft, a threaded rod is rotatably mounted on the upper end surface of the transition plate, a threaded groove is opened on the upper part of the placement plate to thread with the threaded rod, a gear is fixedly mounted on the lower end circumferential surface of the threaded rod, a connecting shaft is rotatably mounted on the upper end surface of the transition plate, a first gear that meshes with the gear is fixedly mounted on the portion of the connecting shaft above the transition plate, a second gear is fixedly mounted on the lower end portion of the connecting shaft, eight circumferentially evenly distributed third gears that can mesh with the second gears are rotatably mounted on the upper end surface of the placement plate via a gear shaft, a driving assembly for driving the third gears to rotate is provided on the lower end surface of the placement plate, and the number of teeth of the gear is less than the number of teeth of the first gear, and the number of teeth of the second gear is less than the number of teeth of the third gear.

[0016] According to an advantageous embodiment, the drive assembly includes a first sprocket. The lower end of all the gear shafts is fixedly fitted with a first sprocket, and adjacent first sprockets are staggered. Four non-adjacent first sprockets are located in the same plane. The four first sprockets in the same height plane are connected to each other by a first chain. The lower end face of the circular plate is rotatably provided with two left-right distributed and meshing drive gears via a drive shaft. Second sprockets are fixedly fitted on the drive shaft, the foremost gear shaft, and the adjacent right gear shaft. The second sprockets on the drive shaft are connected to the corresponding second sprockets on the gear shafts via second chains. The left drive shaft is connected to an external motor.

[0017] In summary, the present invention has at least one of the following beneficial effects: First, the clamping strip and the mating top plate cooperate with each other. After the circuit board is lowered, the corresponding four clamping mechanisms cooperate with each other to quickly clamp the circuit board, ensuring stability during processing while reducing the time spent clamping the circuit board. At the same time, the release group allows the drilled circuit board to move up quickly, making it easier to remove later, thereby reducing the time spent clamping the circuit board and improving the utilization rate of the processing process.

[0018] Second, in this invention, the adjustment group moves the lower left corner of the circuit board to a specified known position, which facilitates subsequent drilling operations based on this position. Therefore, it reduces the adjustment time for the circuit board position, thereby improving production utilization and being able to adapt to circuit boards of different sizes.

[0019] Third, in this invention, the drive unit enables the placement plate to move up and down continuously. Therefore, during the rotation of the placement plate driven by the rotating shaft, when the placement plate moves from above the circuit board to above the next circuit board, the placement plate moves down again after completing the upward movement. After the placement plate moves up, the external high-precision palletizing robot takes out the circuit board with completed drilling and places the circuit board without drilling. Thus, the equipment can perform drilling operations while continuously placing and taking out circuit boards, which reduces the overall drilling operation time and improves the utilization rate during operation.

[0020] Fourth, the number of teeth of the gear component in this invention is less than the number of teeth of the first gear, so that when the first gear 534 rotates by the same angle, the gear component drives the threaded rod to rotate by a larger angle, thereby ensuring that the distance of the up and down movement of the placement plate meets the requirements. In addition, the number of teeth of the second gear is less than the number of teeth of the third gear, so that the second gear can fully mesh with the third gear as the rotating shaft rotates, and the second gear can rotate more times than the third gear, which is convenient for subsequent control of the up and down movement of the placement plate.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 As shown, a production utilization rate improvement device for liquid crystal display circuit boards includes: a circular plate 1, which is fixedly disposed on the upper surface of four supports. The upper surface of the circular plate 1 is fixedly disposed with four groups of circumferentially evenly distributed plates, each group of plates including four right-angled plates. The upper surface of the four right-angled plates is fixedly disposed with an annular mounting plate 2.

[0034] The mounting plate 2 has four sets of clamping mechanisms 3 evenly distributed around its circumference on its upper surface. The four sets of clamping mechanisms 3 work together to clamp and fix the placed circuit board.

[0035] The drilling mechanism 5 is provided with a rotating shaft 4 rotatably mounted on the upper end face of the circular plate 1. The rotating shaft 4 is connected to an external motor and is equipped with a drilling mechanism 5 for drilling the circuit board.

[0036] During operation, the external high-precision palletizing robot first moves the PCB circuit board that needs to be drilled onto the mounting plate 2. Then, the clamping mechanism 3 clamps and fixes it. Next, the drilling mechanism 5 drills holes in the circuit board. At the same time, the external motor 1 drives the rotating shaft 4 to rotate. Therefore, as the rotating shaft 4 drives the drilling mechanism 5 to rotate, it drills holes in all the circuit boards placed on the mounting plate 2. Meanwhile, the external high-precision palletizing robot removes the circuit board that has been drilled and replaces it for processing.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, a production utilization rate improvement device for liquid crystal display circuit boards is disclosed. The clamping mechanism 3 includes a rectangular plate 30. Taking the clamping mechanism 3 on the front side of the circular plate 1 placed in front as an example, the rectangular plate 30 is fixedly installed on the upper end surface of the mounting plate 2 in front. Two left-right symmetrical mounting vertical plates are fixedly installed on the upper end surface of the rectangular plate 30. An L-shaped clamping strip 31 is rotatably installed between the two mounting vertical plates. A pressing plate 32 is rotatably installed on the rear side of the clamping strip 31. A clamping group 33 is provided on the front side of the clamping strip 31 for driving the clamping strip 31 to drive the pressing plate 32 to clamp the circuit board.

[0038] like Figure 6 As shown, a production capacity improvement device for liquid crystal display circuit boards is disclosed. The clamping assembly 33 includes forward moving columns 330. Two left-right symmetrical forward moving columns 330 are slidably mounted on the front end face of the mounting plate 2. A limit plate 331 is fixedly mounted on the front end face of the two forward moving columns 330. A limit groove 332 for limiting the front end of the clamping bar 31 is provided on the limit plate 331. A first spring 333 corresponding to the forward moving columns 330 is provided between the limit plate 331 and the mounting plate 2. A trapezoidal plate 334 is fixedly mounted on the lower end face of the limit plate 331. The rear side of the trapezoidal plate 334 is inclined. A through groove running from top to bottom is provided on the upper end face of the mounting plate 2. A mating top plate 335 is slidably mounted in the through groove. An inclined plate 336 that cooperates with the trapezoidal plate 334 is fixedly mounted on the lower end of the mating top plate 335.

[0039] Taking the clamping mechanism 3 on the front side of the circular plate 1 directly in front as an example, initially, the first spring 333 is in an undeformed state, and at this time, the upper end face of the clamping bar 31 is far away from the mating top plate 335. During operation, after the external high-precision palletizing robot places the circuit board on the mounting plate 2, the lower end face of the circuit board first contacts the mating top plate 335, causing the mating top plate 335 to move downward. The mating top plate 335, through the cooperation between its inclined plate 336 and the trapezoidal plate 334, causes the trapezoidal plate 334 to drive the limiting plate 331 forward, thus stretching the first spring 333 and limiting the movement. The plate 331 limits the clamping bar 31 through the limiting groove 332, causing the clamping bar 31 to rotate backward. At this time, the clamping bar 31 drives the corresponding pressing plate 32 to press and clamp the placed circuit board, that is, it exerts a downward force on the circuit board. This force is greater than the component force indirectly exerted on the mating top plate 335 by the elastic force generated by the stretching of the first spring 333. Therefore, a self-locking is formed between the clamping bar 31, the pressing plate 32 and the mating top plate 335. Thus, the four clamping mechanisms 3 on the same mounting plate 2 clamp and limit the placed circuit board, which facilitates subsequent drilling operations.

[0040] like Figure 7 and Figure 8 As shown, a production utilization rate improvement device for liquid crystal display circuit boards is provided on the upper end surface of the mounting plate 2, which is provided with an adjustment component for adjusting the position of the circuit board. The adjustment component includes four axially evenly distributed adjustment groups 34. Each adjustment group 34 includes a slider groove 340. Two mutually symmetrical slider grooves 340 are opened on the upper end surface of the mounting plate 2. A right-angled trapezoidal adjustment plate 341 is slidably arranged in the two slider grooves 340 through a sliding block. The upper side of the end face of the adjustment plate 341 that contacts the circuit board is inclined. Two mutually symmetrical second springs 342 are fixedly arranged between the adjustment plate 341 and the rectangular plate 30. An L-shaped plate 343 is fixedly arranged on the right end face of the left rectangular plate 30 and the rear end face of the front rectangular plate 30. The spring coefficient of the second springs 342 on the left rectangular plate 30 and the front rectangular plate 30 is smaller than that of the second springs 342 on the rear rectangular plate 30 and the right rectangular plate 30.

[0041] When placing the circuit board, the four sides of the circuit board first contact the inclined surface of the adjustment plate 341. As the circuit board continues to move downward, the adjustment plate 341 moves closer to the corresponding rectangular plate 30. At this time, the second spring 342 is compressed. After the circuit board is placed, the elastic force generated by the compression deformation of the second spring 342 causes the four adjustment plates 341 to clamp the four sides of the placed circuit board. At the same time, because the spring constant of the second spring 342 on the left rectangular plate 30 and the front rectangular plate 30 is smaller than that on the rear rectangular plate 30 and the right rectangular plate 30, the adjustment plate 341 on the left and the front adjustment plate 341 are finally in close contact with the corresponding L-shaped plate 343. Therefore, the lower left corner of the circuit board moves to the designated known position, which is convenient for subsequent drilling operations based on this position. It can also adapt to circuit boards of different sizes, and the trapezoidal surface of the adjustment plate 341 facilitates the placement and installation of the circuit board.

[0042] like Figure 7 As shown, a production capacity improvement device for liquid crystal display circuit boards is provided. The mounting plate 2 is provided with a release group 35 for quick contact and simultaneous removal of the circuit board from the clamping state. The release group 35 includes a circular groove. The upper end face of the mounting plate 2 has four circular grooves arranged in a matrix. A circular column 350 is slidably disposed in the circular groove. A circular lifting plate 351 is fixedly disposed on the upper end face of the circular column 350. A connecting plate 352 is fixedly disposed on the lower end face of the circular column 350. A first cylinder corresponding to the connecting plate 352 is fixedly disposed on the lower end face of the mounting plate 2. A control column 353 fixedly connected to the corresponding mating top plate 335 is fixedly disposed between two adjacent circular columns 350.

[0043] After the drilling mechanism 5 finishes drilling the placed circuit board, the first cylinder operates, causing its telescopic end to retract the corresponding connecting plate 352. Therefore, the connecting plate 352, through the circular column 350, drives the corresponding lifting plate 351 to lift the circuit board. During the upward movement of the circular column 350, the circular column 350, through the corresponding control column 353, drives the mating top plate 335 to move upward. Therefore, the control column 353 exerts an upward force on the mating top plate 335, thereby releasing the self-locking between the clamping bar 31, the pressing plate 32, and the mating top plate 335. At the same time, this force, plus the elastic force generated by the stretching of the first spring 333, indirectly acts on the mating top plate 335, which is greater than the force exerted by the clamping bar 31 on the circuit board. Therefore, the circuit board moves upward, and then the external high-precision palletizing robot collects the circuit board.

[0044] like Figure 2As shown, a production capacity improvement device for liquid crystal display circuit boards is provided. The drilling mechanism 5 includes a vertical groove 50. The rotating shaft 4 has a vertical groove 50. A placement plate 51 is slidably arranged in the vertical groove 50 through a vertical block. A drilling component 52 for drilling the circuit board is provided at the lower end of the placement plate 51. A driving component 53 for driving the drilling component 52 to move intermittently up and down is provided on the placement plate 1 and the rotating shaft 4.

[0045] like Figure 5 As shown, a production capacity improvement device for liquid crystal display circuit boards is provided. The drilling component 52 includes a square groove 520. The front end face of the placement plate 51 is provided with a square groove 520. A horizontal plate 521 is slidably disposed in the square groove 520 by an electric slider 1. A horizontal groove is provided on the lower end face of the horizontal plate 521. An external drilling device is slidably disposed in the horizontal groove by an electric slider 2.

[0046] like Figure 3 As shown, a production capacity improvement device for liquid crystal display circuit boards includes a drive component 53 comprising a transition plate 530. The transition plate 530 is fixedly mounted on the circumferential surface of the rotating shaft 4. A threaded rod 531 is rotatably mounted on the upper end surface of the transition plate 530. A threaded groove for threaded engagement with the threaded rod 531 is formed on the upper surface of the placement plate 51. A gear component 532 is fixedly sleeved on the lower end circumferential surface of the threaded rod 531. A connecting shaft 533 is rotatably mounted on the upper end surface of the transition plate 530. The portion of the connecting shaft 533 located above the transition plate 530... A first gear 534 is fixedly sleeved and meshes with the gear component 532. A second gear 535 is fixedly sleeved on the lower end of the connecting shaft 533. Eight circumferentially evenly distributed third gears 536 that can mesh with the second gear 535 are rotatably arranged on the upper end surface of the placing circular plate 1 via the gear shaft. A drive group 537 for driving the third gears 536 to rotate is provided on the lower end surface of the placing circular plate 1. The number of teeth of the gear component 532 is less than the number of teeth of the first gear 534, and the number of teeth of the second gear 535 is less than the number of teeth of the third gear 536.

[0047] like Figure 4As shown, a production capacity improvement device for liquid crystal display circuit boards includes a drive group 537 comprising a first sprocket 5370. The lower ends of all gear shafts are fixedly fitted with the first sprocket 5370, and adjacent first sprockets 5370 are staggered. Four non-adjacent first sprockets 5370 are located in the same plane. The four first sprockets 5370 in the same height plane are connected to each other by a first chain. The lower end face of the circular plate 1 is rotatably provided with two left-right distributed and meshing drive gears 5371 via a drive shaft. The drive shaft, the foremost gear shaft, and the adjacent right gear shaft are all fixedly fitted with second sprockets 5372. The second sprockets 5372 on the drive shaft are connected to the corresponding second sprockets 5372 on the gear shaft via second chains. The left drive shaft is connected to an external motor.

[0048] by Figure 1 The position of the drilling mechanism 5 is explained below. During operation, after the external high-precision palletizing robot places the circuit board to be drilled on the mounting plate 2 and the external drilling equipment performs the drilling, the electric slider one and electric slider two work to move the external drilling equipment to the designated position. At the same time, the external motor two works to make the left drive gear 5371 rotate forward through the left drive shaft. Simultaneously, the meshing between the two drive gears 5371 causes the right drive shaft to rotate in reverse. Therefore, through the transmission of the second chain, the gear shaft in front and its adjacent gear shaft on the right rotate synchronously. Thus, through the transmission of the two first chains, the corresponding gear shaft is rotated through the first sprocket 5370. The gear shafts rotate synchronously, meaning the third gear 536 rotates, and the rotation directions of two adjacent third gears 536 are opposite. The meshing of the third gear 536 with the second gear 535 causes the connecting shaft 533 to rotate. Simultaneously, the meshing of the connecting shaft 533 with the first gear 534 and the second gear 535 causes the threaded rod 531 to rotate. The threaded engagement between the threaded rod 531 and the placement plate 51 controls the upward movement of the placement plate 51. Then, the external motor 1 operates, causing the placement plate 51 to rotate clockwise via the rotating shaft 4. When the second gear 535 and the third gear 536 stop meshing, the external motor 2 stops rotating. When the placement plate 51 rotates to the position where the second gear 535 and the third gear 536 are engaged... Figure 1After the third gear 536 to the left of the third gear 536 in the center front meshes with each other, the external motor 2 continues to rotate, thus repeating the above transmission relationship to make the placement plate 51 move down a certain height. Then, as the rotating shaft 4 continues to rotate, and when the second gear 535 stops meshing with the corresponding third gear 536, the external motor 2 stops rotating. Then the placement plate 51 moves to directly above the mounting plate 2 on the left. At this time, the second gear 535 meshes with the third gear 536 on the left, and the external drilling equipment performs drilling operations. After the drilling operation on the circuit board on the left is completed, the external motor... The second operation repeats the above transmission relationship to make the placement plate 51 move upward. Therefore, during the rotation of the placement plate 51 driven by the rotating shaft 4, the placement plate 51 moves up and down continuously through the drive group 537. When the placement plate 51 moves from above the circuit board to above the next circuit board, the placement plate 51 moves down again after completing the upward movement. After the placement plate 51 moves upward, the external high-precision palletizing robot takes out the circuit board with completed drilling and puts in the circuit board without drilling. Therefore, the equipment can perform drilling operations while loading and unloading materials, thereby improving the utilization rate during operation.

[0049] Furthermore, the number of teeth of the gear 532 is less than that of the first gear 534, so that when the first gear 534 rotates by the same angle, the gear 532 drives the threaded rod 531 to rotate by a larger angle, thereby ensuring that the vertical movement distance of the placement plate 51 meets the requirements. In addition, the number of teeth of the second gear 535 is less than that of the third gear 536, so that the second gear 535 can fully mesh with the third gear 536 as the rotating shaft 4 rotates, and the second gear 535 can rotate more times than the third gear 536, which facilitates the subsequent control of the vertical movement of the placement plate 51.

[0050] In actual operation, the external high-precision palletizing robot first places the circuit board that needs to be drilled on the mounting plate 2. Then, the clamping bars 31 of the four clamping mechanisms 3 on the mounting plate 2 cooperate with the corresponding mating top plate 335 to limit and clamp the placed circuit board. At the same time, the adjustment components set up adjust the position of the circuit board.

[0051] Then, when the external motor starts working, the rotating shaft 4 drives the drilling mechanism 5 to rotate. The drive group 537 in the drilling mechanism 5 works to make the placement plate 51 move up and down. During the movement, the external drilling equipment drills holes in the placed circuit board. During the rotation of the placement plate 51, the release group 35 works to push out the drilled circuit board. At the same time, the external high-precision palletizing robot takes out the drilled circuit board and places the undrilled circuit board on the mounting plate 2, and repeats the above operation.

[0052] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
