Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to an integrated loading and unloading machine for glass carrier plates. Background Technology

[0002] In the manufacturing process of circuit boards, glass substrates are a core support material with high precision characteristics. When circuit boards undergo processes such as photolithography, etching, lamination, and electroplating, the glass substrate provides rigid support to ensure flatness throughout the process.

[0003] In existing circuit board manufacturing systems, the loading and unloading of glass substrates are each handled by a separate handling robot. Due to the limited loading and unloading speed, the handling robots also have a long waiting time after completing their tasks, which reduces the utilization rate of the handling robots and makes the cost of using two handling robots high.

[0010] In some embodiments, the bracket is further fixed with a plurality of vertically extending top rods that can pass between adjacent rotation axes and lift the glass carrier plate.

[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0032] An embodiment of this utility model provides an integrated loading and unloading machine for glass carrier plates, such as... Figure 1 and Figure 2 As shown, the device includes a feeding conveyor 101, a handling robot 200, a discharging conveyor 102, a first lifting device 301, a second lifting device 302, and a positioning device 400. The first lifting device 301 is located at the feeding end of the feeding conveyor 101, the positioning device 400 is located at the discharging end of the feeding conveyor 101, and the second lifting device 302 is located at the discharging end of the discharging conveyor 102.

[0033] During the loading operation, operators can manually place the glass carrier plate 10 to be loaded onto the first lifting device 301, or other mechanical equipment can place the glass carrier plate 10 to be loaded onto the first lifting device 301. The first lifting device 301 is used to place the glass carrier plate 10 downwards onto the loading conveyor 101. The loading conveyor 101 is used to transport the glass carrier plate 10 to the positioning device 400. The positioning device 400 is used to position the glass carrier plate 10 so that it is in a uniform and predetermined position, so that the handling robot can accurately grasp the glass carrier plate 10. The handling robot 200 is used to remove the positioned glass carrier plate 10 and can send the glass carrier plate 10 into the production line.

[0034] During the unloading operation, the handling robot 200 can grab the glass carrier plate 10 to be unloaded on the production line and place it on the unloading conveyor 102. The unloading conveyor 102 is used to transport the glass carrier plate 10 to the second lifting device 302. The second lifting device 302 is used to lift the glass carrier plate 10 on the unloading conveyor 102 so that the operator can manually remove the glass carrier plate 10 lifted by the second lifting device 302, or the glass carrier plate 10 lifted by the second lifting device 302 can be removed by mechanical equipment at other workstations.

[0035] In this embodiment, the same handling robot 200 is used for both loading and unloading operations. Since it is difficult to perform loading and unloading operations simultaneously, the handling robot 200 can utilize this time difference to reduce its waiting time and improve its utilization rate. At the same time, it is not necessary to configure a separate handling robot 200 for the loading conveyor 101 and the unloading conveyor 102, thus reducing the number of handling robots 200 and lowering production costs.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, both the loading conveyor 101 and the unloading conveyor 102 include a conveying drive assembly, multiple rotating shafts 110 distributed along the conveying direction, and rollers 120 coaxially connected to the rotating shafts 110. The rotating shafts 110 are connected to the conveying drive assembly, which drives the rotating shafts 110 to rotate. The glass carrier plate 10 is placed on the rollers 120. When the rotating shafts 110 rotate, the rollers 120 rotate accordingly, and the rotation of the rollers 120 drives the glass carrier plate 10 to move along the conveying direction.

[0037] This embodiment uses a roller-type conveying device with a gap between two adjacent rotating shafts 110, providing space for the first lifting device 301, the second lifting device 302, and the positioning device 400 to move from below the rotating shaft 110 or extend above the rotating shaft 110.

[0038] The path formed by the feeding conveyor 101 and the unloading conveyor 102 driving the glass carrier 10 to move is the conveying path of the glass carrier 10. The conveying drive assembly is already in the prior art, and its specific structure will not be described in detail.

[0039] Furthermore, the loading conveyor 101 and unloading conveyor 102 are arranged side by side. This design reduces the length of the production line, minimizes the space occupied in the factory, and facilitates simultaneous operation by workers. The handling robot 200 is located between the loading conveyor 101 and the unloading conveyor 102. This layout is more rational, as the handling robot 200 is relatively close to the loading and unloading conveyors 101 and 102, reducing the working time for the handling robot 200 to switch from the loading conveyor 101 to the unloading conveyor 102 and improving production efficiency.

[0040] In some embodiments, such as Figure 3-5As shown, the first and second lifting devices can adopt the same structure; the first lifting device will be used as an example for explanation. The first lifting device includes a lifting drive assembly 310, a bracket 320, and two support bars 330. The lifting drive assembly 310 and bracket 320 are both positioned below the rotating shaft 110 to avoid interfering with the transport of the glass carrier. The two support bars 330 are both positioned above the rotating shaft 110, located on opposite sides of the glass carrier's transport path. Both support bars 330 extend along the transport direction, allowing the glass carrier to move between them. Because the support bars 330 extend along the transport direction, once their initial positions are determined, they are unlikely to interfere with the transport of the glass carrier. The inner surfaces of the two support bars 330 each have protruding supports 331 for supporting the glass carrier. Both support bars 330 are connected to the bracket 320. The lifting drive assembly 310 is connected to the bracket 320. The lifting drive assembly 310 is used to drive the bracket 320 to move vertically, which in turn can drive the support bars 330 and the support block 331 to move vertically. The support block 331 can move downwards to below the conveying path of the glass carrier plate.

[0041] by Figure 5 For example, since the glass carrier is placed on the roller 120, the conveying path of the glass carrier is located at the top of the roller 120. The support block 331 can move downward to below the top of the roller 120, so that the glass carrier can be lifted from the bottom or placed on the roller 120.

[0042] During the loading operation, the lifting drive assembly 310 of the first lifting device first causes the support 320 to move upward, and the operator or other mechanical equipment can place the glass carrier plate on the support block 331. The support blocks 331 on the two support bars 330 respectively lift the glass carrier plate from the bottom of both sides of the glass carrier plate. Then, the lifting drive assembly 310 of the first lifting device drives the support 320 to move downward until the support block 331 moves downward to below the conveying path of the glass carrier plate. The glass carrier plate will then be placed on the roller 120, and the roller 120 can then convey the glass carrier plate.

[0043] During the unloading operation, the lifting drive assembly 310 of the second lifting device first causes the support 320 to move downward, and the support block 331 moves downward to below the conveying path of the glass carrier plate to wait for the glass carrier plate; after the unloading conveying device moves the glass carrier plate above the support block 331 of the second lifting device, the lifting drive assembly 310 of the second lifting device then drives the support 320 to move upward, and the support block 331 moves upward to above the conveying path of the glass carrier plate. The support blocks 331 on the two support bars 330 respectively lift the glass carrier plate from the bottom of both sides of the glass carrier plate, so that the glass carrier plate is separated from the roller 120.

[0044] Furthermore, multiple vertically extending top rods 340 are fixed on the bracket 320. The top rods 340 can pass through the adjacent rotating shafts 110 and lift the glass carrier plate. Based on the support block 331, the added top rods 340 can share the force of the support block 331, increase the support position, and thus lift the glass carrier plate more stably. It can also avoid stress concentration and make the glass carrier plate less prone to damage.

[0045] In some embodiments, such as Figure 3-5 As shown, the bottom surface of the support block 331 is flush with the bottom surface of the support bar 330. Since the support bar 330 is located above the rotating shaft 110, the downward movement distance of the support block 331 is constrained by the contact between the support bar 330 and the rotating shaft 110. When the bottom surface of the support block 331 is flush with the bottom surface of the support bar 330, it is easier to control the downward movement distance of the support block 331. This allows the support block 331 to move downward to below the conveying path of the glass carrier plate, while also ensuring that the support bar 330 does not touch the rotating shaft 110.

[0046] In some embodiments, such as Figure 3-5 As shown, both the first and second lifting devices further include a guide plate 351 disposed below the bracket 320. The bracket 320 is fixed with a guide rod 352 extending vertically. A guide cylinder 353 adapted to the guide rod 352 is fixed on the guide plate 351. The guide rod 352 passes through the guide cylinder 353 and can slide along it. In this embodiment, the relative sliding between the guide rod 352 and the guide cylinder 353 guides the movement of the bracket 320, ensuring that the bracket 320 moves vertically and reducing directional deviation.

[0047] In some embodiments, such as Figure 3-5 As shown, both the first and second lifting devices further include two sets of connecting members 360. The lower ends of both sets of connecting members 360 are connected to the bracket 320, and the upper ends of both sets of connecting members 360 pass between adjacent rotating shafts 110. The upper ends of both sets of connecting members 360 are respectively connected to two support bars 330. In this embodiment, the bracket 320 and the support bars 330 are connected through the connecting members 360, and the connecting members 360 do not interfere with the rotating shafts 110.

[0048] In some embodiments, such as Figure 3-5 As shown, the lifting drive assembly 310 can be a vertically arranged cylinder, and the cylinder's push rod is connected to the bracket 320.

[0049] In some embodiments, such as Figure 1 , Figure 2 and Figure 6As shown, the positioning device 400 includes a front stop 410 disposed in front of the conveying path of the glass carrier 10. When the glass carrier moves along the conveying direction, the front stop 410 can block the glass carrier from moving further, so that the glass carrier is held behind the front stop 410 to position the glass carrier.

[0050] Furthermore, the positioning device 400 also includes a first centering member 421, a second pair of intermediate members 422, and a centering drive assembly 430. The first centering member 421 and the second pair of intermediate members 422 are respectively disposed on both sides of the conveying path of the glass carrier plate. The first centering member 421 and the second pair of intermediate members 422 are both connected to the centering drive assembly 430. The centering drive assembly 430 is used to drive the first centering member 421 and the second pair of intermediate members 422 to move towards each other synchronously or move away from each other.

[0051] When the glass carrier moves to the front stop 410, the centering drive assembly 430 can drive the first centering member 421 and the second pair of intermediate members 422 to move towards each other synchronously. The first centering member 421 and the second pair of intermediate members 422 will push the glass carrier to move in a direction perpendicular to the conveying direction, so that the glass carrier is centered in a position perpendicular to the conveying direction, so as to further position the glass carrier in a direction perpendicular to the conveying direction, so that the glass carrier can be more accurately placed in the ideal position, making it easier for the handling robot to accurately grasp the glass carrier.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, the centering drive assembly 430 includes a cylinder arranged perpendicular to the conveying direction, and the cylinder push rod is connected to the corresponding first centering member 421 and second intermediate member 422.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
