Description

Technical Field

[0001] This utility model relates to the field of glass surface treatment technology, and in particular to a segmented conveyor line and transfer system for a spraying machine. Background Technology

[0002] In glass surface treatment processes, spray coating machines are typically used to apply functional liquids, such as anti-glare (AG) solutions or anti-fingerprint (AF) solutions, to optimize the anti-reflective and anti-fouling properties of the glass surface, thereby enhancing the visual experience and product added value. Automated spray coating production lines are usually equipped with conveyor systems to transport glass substrates between processing stations, ensuring the continuity and automation of the production process.

[0003] Currently, the common conveying method is a linear single-line layout, where fixtures carrying glass are placed sequentially on a single conveyor line and transported from one workstation to the next. This method is structurally simple and stable, suitable for some basic production scenarios. However, its inherent sequential conveying mechanism has certain efficiency bottlenecks: because the conveyor line operates continuously in one direction, any fixture must complete the transport of its entire path before the conveyor line can perform a new loading or unloading operation. Especially when the distance between two workstations is large, this method will significantly prolong the ineffective waiting time of the fixtures during the conveying process, thus restricting the improvement of overall production efficiency and making it difficult to meet the demands of high-efficiency, high-cycle modern manufacturing. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems of the prior art and provide a segmented conveyor line and transfer system for a spraying machine. While ensuring the stability of fixture conveying, it effectively improves the efficiency bottleneck caused by the long station spacing in the traditional single-line conveying method.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] The spraying machine uses a segmented conveyor line, including a support base, on which two linear conveyor drive devices are connected and arranged in the front-to-back direction.

[0007] Both linear conveyor drive devices have linear conveyor sections, and the output end of the linear conveyor drive device is connected to a support frame that can slide back and forth on the linear conveyor section. The two support frames are in an overlapping state in the left and right directions.

[0008] A lifting drive assembly is provided on the support base. The output end of the lifting drive assembly is connected to a lifting frame located at the junction of two linear transmission drive devices and can move up and down. The lifting frame has two lifting support plates located on both sides of the support frame.

[0009] Furthermore, the two linear transmission drive devices are staggered in the left-right direction, and the output end of the linear transmission segment of one linear transmission drive device and the input end of the linear transmission segment of the other linear transmission drive device have overlapping areas in the front-back direction.

[0010] Furthermore, the inner end of the lifting support plate is provided with a support groove, which makes the outer end of the lifting support plate have a side stop section.

[0011] Furthermore, the support base is provided with a transmission support frame at the junction of the two linear transmission drive devices, and a lifting limit guide rail is provided on the transmission support frame.

[0012] The outer end of the lifting support plate is provided with a lifting limit slider that cooperates with the lifting limit guide rail;

[0014] Furthermore, the lifting drive assembly includes a lifting rotation drive device and two gearboxes, and the output end of the lifting rotation drive device is connected to a synchronizing rod that passes through the two gearboxes;

[0015] A rotating component is rotatably mounted inside the gearbox and sleeved on the synchronizing rod. A lifting component that can cooperate with the rotating component is connected to the gearbox and can move up and down. The top ends of the two lifting components are respectively connected to the bottom ends of the two lifting support plates.

[0016] Furthermore, the top end of the support frame has a vacuum cavity, and several uniformly distributed vacuum channels are distributed inside the vacuum cavity. At least two limiting posts are provided at the top end of the support frame.

[0017] The support frame has a heating structure in the middle and a heat insulation structure located below the heating structure;

[0018] The bottom end of the support frame has a load-bearing connection structure.

[0019] A transfer system for a spraying machine includes at least two segmented conveyor lines as described in any of the preceding items, wherein the at least two segmented conveyor lines are arranged alternately in the left-right or front-back direction.

[0020] When at least two segmented conveyor lines are arranged in a left-right direction, a transfer gripping component that can move left-right is provided above the two straight conveyor segments of the two adjacent segmented conveyor lines located in the same segment.

[0021] When at least two segmented conveyor lines are arranged in a forward-backward direction, a transfer gripping assembly that can move forward-backward is provided above the output and input ends of two adjacent segmented conveyor lines.

[0022] Furthermore, the transfer clamping assembly includes a clamping fixed frame and a clamping movable frame that is movably connected to the clamping fixed frame. The clamping fixed frame is also provided with a clamping up and down driving device for driving the clamping movable frame to move up and down.

[0023] The gripping movable frame is equipped with two gripping telescopic drive devices arranged in opposite directions. The output end of each gripping telescopic drive device is connected to a jaw clamp. The two gripping telescopic drive devices act on the two jaw clamps, so that the two jaw clamps can move towards each other or away from each other.

[0029] This invention offers the following advantages: Through an innovative segmented conveying design and collaborative control mechanism, it achieves efficient and stable transfer of fixtures between multiple workstations in an automated glass spraying production line. Its core advantages can be summarized as follows:

[0030] 1. In the segmented conveyor line, a double linear conveyor drive device with staggered left and right arrangements is adopted, and the input and output ends of adjacent linear conveyor sections overlap in the front-to-back direction. Combined with a lifting and transfer mechanism, seamless connection of fixtures between segmented conveyor lines is achieved. This design allows the rear conveyor section to immediately return to perform loading operations after completing fixture handover, while the front conveyor section can simultaneously receive and transport fixtures to the next workstation, effectively shortening the waiting time of fixtures during conveying and significantly improving the overall conveying cycle time and equipment utilization. Specifically, the overlapping arrangement of two support frames in the left-to-right direction, along with the coordinated use of lifting limit guides and sliders, ensures that the fixture remains stable during transfer, preventing deviation or shaking.

[0031] 2. In the transfer system, segmented conveyor lines are suitable not only for front-to-back arrangements but also for left-to-right production line layouts, supporting production line expansion and flexible configuration. The transfer gripping component works in conjunction with the segmented conveyor line, allowing the jig to be transferred to an adjacent segmented conveyor line while a specific process is being performed on one line. This enables flexible scheduling and parallel operation between different workstations, effectively shortening the jig's dwell time on the production line and improving overall production efficiency and equipment utilization. The transfer drive component and transfer gripping component enable stable gripping, lifting, and continuous transfer of the jig. Attached Figure Description

[0050] To enable those skilled in the art to better understand this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0051] Example 1

[0052] like Figures 1 to 14 As shown, the spraying machine uses a segmented conveyor line, including a support base 3, on which two linear conveyor drive devices 1 are arranged in a front-to-back direction.

[0053] Both linear transmission drive devices 1 have linear transmission sections 2. The output end of the linear transmission drive device 1 is connected to a support frame 4 that can slide back and forth on the linear transmission section 2. The two support frames 4 are in an overlapping state in the left and right directions.

[0054] A lifting drive assembly is provided on the support base 3. The output end of the lifting drive assembly is connected to a lifting frame located at the junction of the two linear transmission drive devices 1 and can move up and down. The lifting frame has two lifting support plates 6 located on both sides of the support frame 4.

[0055] In this embodiment, the linear conveyor drive device 1 can be a modular slide table. Taking the configuration of two linear conveyor drive devices 1 as an example, as follows... Figure 6 As shown, the two linear transmission drive devices 1 are staggered in the left-right direction, and the output end of the linear transmission segment 2 of one linear transmission drive device 1 and the input end of the linear transmission segment 2 of the other linear transmission drive device 1 have overlapping areas in the front-back direction.

[0056] In application, the fixture containing the glass slides is placed on the support frame 4 located in the rear linear conveyor section 2. In this embodiment, the fixture's lateral width should be slightly larger than the lateral width of the support frame 4. Figure 4 As shown. The linear conveyor drive 1 is activated to drive the support frame 4 forward. When it moves to a specific area of ​​the lifting frame, the lifting drive assembly is activated to drive the lifting frame upward. At this time, the two lifting support plates 6 contact the left and right sides of the fixture respectively. As the lifting frame continues to move upward, the fixture will also move upward along with the lifting support plates 6 until it detaches from the aforementioned support frame 4. At this time, the support frame 4 located on the rear linear conveyor section 2 can move backward under the drive of the linear conveyor drive 1 to perform a new loading operation, while the support frame 4 located on the front linear conveyor section 2 moves backward under the drive of the linear conveyor drive 1 to directly below the aforementioned fixture. At this point, the lifting drive assembly is activated to move the lifting frame downwards. The fixture will follow the downward movement of the lifting support plate 6 until it is placed on the aforementioned support frame 4. Then, the linear conveyor drive 1 located at the front is activated, which moves the aforementioned support frame 4 forward to the next workstation. After the glass sheet on the fixture has undergone the corresponding operation, the fixture unloading operation can be performed, and the aforementioned support frame 4 can be idled and prepared to move backward to receive new conveying work. During the forward movement of the aforementioned support frame 4, the linear conveyor drive 1 located at the rear can convey the newly loaded fixture to the junction of the two linear conveyor sections 2, and so on.

[0057] As can be seen, this utility model adopts a segmented conveying design, which can coordinate the loading, conveying and unloading operations of the fixture, thereby effectively improving the conveying efficiency of the fixture between two workstations.

[0058] The two support frames 4 are aligned in the left-right direction, which improves the stability of the fixture during transfer between the two linear transmission sections 2.

[0059] Two linear conveyor drive units 1 are staggered in the left-right direction, and the output end of one linear conveyor segment 2 of the two linear conveyor drive units 1 overlaps with the input end of the other linear conveyor segment 2 in the front-back direction. This allows the output end of the linear conveyor drive unit 1 to connect to the middle area of ​​the bottom of the support frame 4, and also ensures that both support frames 4 are located directly below the lifting frame, thus better facilitating the jig transfer operation. This not only improves the stability of the support frame 4's movement, but also enhances the stability of the jig's movement.

[0060] Preferably, the inner end of the lifting support plate 6 is provided with a support groove 7, and the support groove 7 makes the outer end of the lifting support plate 6 have a side stop section 30.

[0061] In this embodiment, the support groove 7 is used to support the bottom area of ​​the fixture, and the side stop section 30 can be used to limit the outer end area of ​​the fixture. In this way, the fixture can be prevented from accidentally shifting during the up and down movement, thereby improving the stability of the fixture's up and down movement.

[0062] Preferably, the support base 3 is provided with a transmission support frame 8 at the junction of the two linear transmission drive devices 1, and the transmission support frame 8 is provided with a lifting limit guide rail 9.

[0063] The outer end of the lifting support plate 6 is provided with a lifting limiting slider 10 that cooperates with the lifting limiting guide rail 9;

[0064] The conveyor support frame 8 is also equipped with a lifting limit frame 5.

[0065] In this embodiment, the cooperation between the lifting limit guide rail 9 and the lifting limit slider 10 can improve the stability of the two lifting support plates 6 moving up and down, thereby improving the stability of the fixture moving up and down.

[0066] The lifting limit bracket 5 is used to limit the extreme position of the jig's upward movement to prevent the jig from moving excessively.

[0067] Preferably, the lifting drive assembly includes a lifting rotation drive device 12 and two gearboxes 13, and the output end of the lifting rotation drive device 12 is connected to a synchronizing rod 14 that passes through the two gearboxes 13;

[0068] A rotating component 15 is rotatably mounted inside the gearbox 13 and sleeved on the synchronizing rod 14. A lifting component 16 that can cooperate with the rotating component 15 is connected to the gearbox 13 in a way that can move up and down. The top ends of the two lifting components 16 are respectively connected to the bottom ends of the two lifting support plates 6.

[0069] In this embodiment, the rotating component 15 can be a worm gear, the lifting component 16 can be a worm, and the lifting rotation drive device 12 is a motor. Activating the lifting rotation drive device 12 causes the synchronous rod 14 to rotate, which in turn drives the rotating component 15 within the two gearboxes 13 to rotate. Through the cooperation of the worm gear and the worm, the two lifting components 16 can move synchronously up and down, thereby driving the two lifting support plates 6 to move synchronously up and down. The lifting drive assembly can be connected to the lower part of the conveyor support frame 8 via the drive mounting bracket 40. The lifting component 16 can be connected to the bottom end of the lifting support plate 6 via the connecting piece 41.

[0070] Preferably, the top end of the support frame 4 has a vacuum cavity, and a plurality of uniformly distributed vacuum channels 17 are distributed in the vacuum cavity. At least two limiting posts 11 are provided at the top end of the support frame 4.

[0071] The support frame 4 has a heating structure in the middle and a heat insulation structure located below the heating structure;

[0072] The bottom end of the support frame 4 has a load-bearing connection structure.

[0073] This embodiment utilizes a fixture 34. The top of the fixture 34 has a receiving groove 48 that fits into the glass sheet 42 to be processed. The bottom of the fixture 34 has a closed plane 35 that covers and seals the vacuum chamber of the support frame 4. The fixture 34 also has several heat-conducting adsorption holes 33 running vertically through it, connecting the receiving groove 48 to the vacuum channel 17. In application, an air generator is connected to the vacuum chamber. Activating the air generator creates a negative pressure within the vacuum chamber. The fixture is then adsorbed by the cooperation between the vacuum channel 17 and the closed plane 35. The glass sheet can also be directly adsorbed through the heat-conducting adsorption holes 33, thus preventing accidental displacement of the fixture and glass sheet during movement. Furthermore, the heating structure of the support frame 4 can heat the glass sheet through the fixture, thereby improving the liquid spraying effect.

[0074] like Figure 13 As shown, the fixture 34 may also be provided with at least two limiting holes 36 that are respectively inserted and cooperate with at least two limiting posts 11. In this way, when the fixture 34 is placed on the support frame 4, the cooperation between the limiting posts 11 and the limiting holes 36 can realize the rapid positioning of the fixture 34 on the support frame 4, which is beneficial to the stability of the fixture 34 in the segmented transmission process.

[0075] Example 2

[0076] like Figures 1 to 22 As shown, the transfer system for the spraying machine includes at least two segmented conveyor lines as described in any of the preceding items, with the at least two segmented conveyor lines arranged alternately in the left-right or front-back directions.

[0077] When at least two segmented transmission lines are arranged in a left-right direction, such as Figure 15As shown, above the two straight conveyor segments 2 of the two adjacent segmented conveyor lines located in the same segment, there are transfer gripping components that can move left and right.

[0078] When at least two segmented transmission lines are arranged in a forward-backward direction, such as Figure 16 As shown, a transfer gripper assembly that can move back and forth is provided above the output and input ends of two adjacent segmented conveyor lines.

[0079] In this embodiment, the transfer gripping component can be used to grip the fixture 34 and realize its transfer operation between at least two segmented conveyor lines.

[0080] Preferably, the transfer clamping assembly includes a clamping fixed frame 22 and a clamping movable frame 23 that is movably connected to the clamping fixed frame 22. The clamping fixed frame 22 is also provided with a clamping up and down driving device 32 for driving the clamping movable frame 23 to move up and down.

[0081] The clamping frame 23 is equipped with two clamping telescopic drive devices 24 arranged in opposite directions. The output end of each clamping telescopic drive device 24 is connected to a claw holder 25. The two clamping telescopic drive devices 24 act on the two claw holders 25, so that the two claw holders 25 can move towards each other or away from each other.

[0082] The gripper holder 25 has at least two grippers 37, and the inner end of the bottom end of the gripper 37 is provided with a hook section 26.

[0083] In this embodiment, the clamping up-and-down driving device 32 can be a cylinder. For example... Figure 20 As shown, the telescopic end of the gripping up-and-down drive device 32 is connected to the gripping movable frame 23, and the cylinder end of the gripping up-and-down drive device 32 is connected to the gripping fixed frame 22. Activating the gripping up-and-down drive device 32 will cause the gripping movable frame 23 to move up and down relative to the gripping fixed frame 22, thus allowing the two-jaw gripper 25 to reach a suitable height for gripping the fixture 34.

[0084] The gripping telescopic drive device 24 can be a cylinder. Synchronously activating the two gripping telescopic drive devices 24 can cause the two jaw grippers 25 to move in opposite directions or away from each other, thereby realizing the gripping action on the fixture 34.

[0085] To improve the stability of the gripping engagement between the two-jaw clamp 25 and the fixture 34, such as Figure 21 As shown, a positioning head 38 may also be provided at the top of the claw section 26, and a positioning hole 39 that can cooperate with the positioning head 38 is provided at the bottom of the fixture 34. When the two-jaw gripper 25 grips the fixture 34, the cooperation between the positioning head 38 and the positioning hole 39 can realize the quick positioning of the fixture 34 on the two-jaw gripper 25, which is beneficial to the stability of the fixture 34 during the transfer process.

[0086] To protect the movable clamping frame 23 from external interference and to limit the vertical movement of the movable clamping frame 23, a limiting protective shell 45 surrounding the movable clamping frame 23 can be provided on the clamping fixed frame 22.

[0087] Preferably, the clamping and fixing frame 22 is provided with upper and lower limit slide rails 27, and the clamping and movable frame 23 is provided with upper and lower limit sliders 28 that cooperate with the upper and lower limit slide rails 27.

[0088] The clamping frame 23 is equipped with a telescopic limiting slide rail 31, and the two claw clamps 25 are each equipped with a telescopic limiting slider 29 that cooperates with the telescopic limiting slide rail 31.

[0089] In this embodiment, the upper and lower limit sliders 28 and the upper and lower limit slide rails 27 cooperate to achieve stable up and down movement of the gripping movable frame 23; the telescopic limit sliders 29 and the telescopic limit slide rails 31 cooperate to achieve stable movement of the two-jaw grippers 25 towards or away from each other.

[0090] Preferably, it further includes a transfer drive component for driving the transfer gripping component to move;

[0091] The transfer drive assembly includes a transfer support frame 18, on which two linear transfer drive devices 19 are arranged at intervals. Each linear transfer drive device 19 has a linear transfer section 20. The output ends of the two linear transfer drive devices 19 are connected to the same transfer connecting frame 21, which can slide on the two linear transfer sections 20. The transfer connecting frame 21 is connected to the transfer clamping assembly. In this embodiment, the linear transfer drive device 19 can be a modular slide table.

[0092] When at least two of the segmented transmission lines are arranged in a left-right direction, such as Figure 17 and Figure 18 As shown, a transfer support frame 18 is provided above each of the two linear transfer segments 2 of the two adjacent segmented conveyor lines. Two linear transfer drive devices 19 are arranged in a front-to-back direction on the transfer support frame 18. Each linear transfer drive device 19 has a linear transfer segment 20 that can cover the two adjacent segmented conveyor lines in a left-to-right direction. The output ends of the two linear transfer drive devices 19 are connected to the same transfer connecting frame 21, which can slide left and right on the two linear transfer segments 20. The transfer clamping assembly is connected to the transfer connecting frame 21. Synchronously activating the two linear transfer drive devices 19 will drive the transfer clamping assembly to move between the two segmented conveyor lines.

[0093] When at least two segmented conveyor lines are arranged in a front-to-back direction (not shown in the figure), a transfer support frame 18 is provided above the output and input ends of two adjacent segmented conveyor lines. Two linear transfer drive devices 19 are arranged in a left-to-right direction on the transfer support frame 18. Each linear transfer drive device 19 has a linear transfer section 20 that can cover the output and input ends of two adjacent segmented conveyor lines in a front-to-back direction. The output ends of the two linear transfer drive devices 19 are connected to the same transfer connecting frame 21 that can slide back and forth on the two linear transfer sections 20. The transfer clamping assembly is connected to the transfer connecting frame 21.
