Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, and in particular relates to processing equipment and glass production lines. Background Technology

[0002] Automotive windshields are typically made of two layers of glass, an inner layer and an outer layer, bonded together. During manufacturing, the inner surface of the inner glass layer needs to be printed with black or colored enamel to form a protective frame. This frame not only serves an aesthetic purpose but also protects the adhesive from UV rays, extending its lifespan. The outer glass layer, on the other hand, usually does not require any printing.

[0003] In existing technologies, devices used for this type of glass processing typically employ a single conveyor line. Inner and outer glass layers are placed simultaneously on this line and then sequentially transported through a printing station. At the printing station, the printing equipment prints the inner glass layers, while the outer glass layers, which do not require processing, are identified at the printing station and skipped. Finally, all glass is transported to the unloading station for unloading. However, this single-conveyor-line processing method has significant drawbacks. First, for the outer glass layers that do not require processing, they must wait at the printing station for the inner glass layers to finish printing before continuing transport, thus limiting the improvement of the overall production cycle time. Second, all glass is mixed on the same conveyor line, which is not conducive to achieving accurate sorting and efficient pairing of inner and outer glass layers before the subsequent lamination process, affecting the continuity and automation of the production process. Utility Model Content

[0004] The purpose of this application is to provide a processing apparatus that addresses the problems of improving production efficiency and reducing the space occupied by the processing apparatus.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a processing apparatus is provided, comprising a material transfer station, a processing station, and a material unloading station arranged sequentially along a first direction. The processing apparatus includes: a first conveyor line for conveying a first workpiece and a second workpiece along the first direction; a processing structure disposed at the processing station for processing the first workpiece; and a second conveyor line spaced apart from the first conveyor line along a second direction for conveying the second workpiece along the first direction, the second direction being angled to the first direction; wherein the first conveyor line conveys the first workpiece and the second workpiece to the material transfer station; the second conveyor line receives the second workpiece at the material transfer station and conveys the second workpiece to the material unloading station for unloading; the first conveyor line conveys the first workpiece to the processing structure; and the first conveyor line receives the processed first workpiece at the processing station and conveys the first workpiece to the material unloading station for unloading.

[0006] In some embodiments, the processing apparatus further includes a transfer structure disposed between the first conveyor line and the second conveyor line, the transfer structure being used to receive the second workpiece at the first conveyor line and transfer the second workpiece to the second conveyor line.

[0007] In some embodiments, the transfer structure is used to transfer the second workpiece along the second direction to move the second workpiece to a position corresponding to one end of the second conveyor line. The transfer structure is also used to transfer the second workpiece along the first direction to convey the second workpiece to the second conveyor line.

[0008] In some embodiments, the transfer structure includes a first frame, a plurality of first conveying rollers disposed on the first frame, and a plurality of first conveyor belts slidably disposed on the first frame in a vertical direction. Each first conveyor belt is respectively disposed between two adjacent first conveying rollers, and each first conveyor belt is raised and lowered relative to each first conveying roller. The first conveying rollers are used to convey the second workpiece along the first direction, and the first conveyor belts are used to convey the second workpiece along the second direction.

[0009] In some embodiments, the first conveyor line includes a second frame, a plurality of second conveyor rollers disposed on the second frame, and a plurality of second conveyor belts slidably disposed on the second frame in a vertical direction. Each second conveyor belt is respectively disposed between two adjacent second conveyor rollers, and each second conveyor belt is raised and lowered relative to each second conveyor roller. The second conveyor rollers are used to convey the first workpiece or the second workpiece in the first direction, and the second conveyor belts are used to convey the second workpiece in the second direction, so as to transfer the second workpiece to the first conveyor belt.

[0010] In some embodiments, the processing apparatus further includes a buffer structure for buffering the first workpiece, the buffer structure being disposed between the transfer station and the processing station; the buffer structure includes a support frame for supporting the first workpiece and slidably disposed thereon, and a drive member located above the support frame for driving the support frame to rise and fall, the first conveyor line having a conveying surface for supporting the first workpiece, the conveying surface having a clearance channel for the support frame to pass through, the support frame lifting the first workpiece conveyed by the first conveyor line to a position away from the conveying surface during its rising stroke, and the support frame lowering the first workpiece carried by it back to the conveying surface during its falling stroke.

[0011] In some embodiments, the support frame includes support rods for supporting the first workpiece, a plurality of support rods being arranged at intervals along the first direction, and a plurality of clearance channels being arranged at intervals along the first direction, each clearance channel being used for each of the support rods to pass through.

[0012] In some embodiments, the first direction and the second direction are perpendicular to each other, and the first conveyor line and the second conveyor line are parallel to each other.

[0013] In some embodiments, the processing apparatus is used to print a preset pattern on the surface of the first workpiece.

[0014] Secondly, a glass production line is provided, which includes the processing apparatus described above. The beneficial effects of this application are as follows: By setting up independent first and second conveyor lines, the first conveyor line transports the first workpiece to the processing structure and unloads the processed first workpiece, while the second conveyor line directly unloads the second workpiece. This achieves the separation and parallel transport of the first and second workpieces. The second workpiece does not need to wait for the first workpiece to finish processing, but is directly and quickly transported to the unloading station via the second conveyor line for unloading. This eliminates the invalid waiting time caused by waiting for the processing of the first target workpiece in the prior art, which can significantly improve the production cycle of the processing device and increase production efficiency. Furthermore, since the first and second workpieces are transported to the same unloading station for unloading, only one set of robotic arm or unloading platform is needed, which helps to reduce the space occupied by the processing device.

[0022] Please see Figures 1 to 4This application provides a processing apparatus, which includes a material transfer station 300, a processing station 400, and a material unloading station 500 sequentially arranged along a first direction a. The processing apparatus includes: a first conveyor line 10 for conveying a first workpiece 210 and a second workpiece 220 along the first direction a; a processing structure 30 disposed at the processing station 400 for processing the first workpiece 210; and a second conveyor line 20 spaced apart from the first conveyor line 10 along a second direction b for conveying the second workpiece 220 along the first direction a. The second direction b is set at an angle to the first direction a; wherein, the first conveyor line 10 conveys the first workpiece 210 and the second workpiece 220 to the transfer station 300; the second conveyor line 20 receives the second workpiece 220 at the transfer station 300 and conveys the second workpiece 220 to the unloading station 500 for unloading; the first conveyor line 10 conveys the first workpiece 210 to the processing structure 30; the first conveyor line 10 receives the processed first workpiece 210 at the processing station 400 and conveys the first workpiece 210 to the unloading station 500 for unloading.

[0023] In this embodiment, the processing apparatus can be applied to a production line for automotive laminated windshields. Specifically, the first workpiece 210 refers to the inner glass layer constituting the windshield; the second workpiece 220 refers to the outer glass layer constituting the windshield; and the processing structure 30 specifically functions to print black or colored ceramic ink onto the inner surface of the inner glass layer to form a light-shielding frame.

[0024] In this embodiment, the first conveyor line 10 is a continuously operating synchronous belt conveyor or roller conveyor. The first conveyor line 10 can receive the first workpiece 210 and the second workpiece 220 from the previous process and transport them to the transfer station 300 along the first direction a. The processing structure 30 is located at the processing station 400. The processing structure 30 may include a high-precision six-axis industrial robot and a dedicated printing head fixed to its end. When the first workpiece 210 is precisely positioned at the processing station 400 along with the first conveyor line 10, the robot moves according to a preset program, driving the printing head to complete a precision printing operation on a specific area of ​​the inner glass. The second conveyor line 20 is arranged in parallel with the first conveyor line 10, but the two maintain a certain distance in the second direction b. The second conveyor line 20 may adopt the same or lighter structure as the first conveyor line 10, and it mainly serves as a dedicated conveying channel for the second workpiece 220.

[0025] The processing apparatus provided in this application embodiment, by setting up independent first conveyor line 10 and second conveyor line 20, the first conveyor line 10 conveys the first workpiece 210 to the processing structure 30 and unloads the processed first workpiece 210, while the second conveyor line 20 directly unloads the second workpiece 220. This realizes the separation and parallel conveying of the first workpiece 210 and the second workpiece 220. The second workpiece 220 does not need to wait for the first workpiece 210 to be processed, but is directly and quickly conveyed to the unloading station 500 for unloading via the second conveyor line 20. This eliminates the invalid waiting time caused by waiting for the processing of the first target workpiece in the prior art, which can significantly improve the production cycle of the processing apparatus and improve production efficiency. Furthermore, since the first workpiece 210 and the second workpiece 220 are conveyed to the same unloading station 500 for unloading, only one set of robotic arm or unloading platform is needed for unloading, which helps to reduce the space occupied by the processing apparatus.

[0026] In the specific working process, the first workpiece 210 and the second workpiece 220 are alternately conveyed to the transfer station 300 by the first conveyor line 10. The control system (not shown in the figure) identifies and tracks the type and position of each workpiece through the sensor 15 or the host computer information, and determines whether the workpiece is the first workpiece 210 or the second workpiece 220. When a workpiece is conveyed to the transfer station 300, the control system triggers an action. For the identified second workpiece 220, it is received by the second conveyor line 20 and directly conveyed to the lower station 500, thus bypassing the subsequent processing structure 30. As for the first workpiece 210, it remains on the first conveyor line 10 and is conveyed to the processing station 400. After the processing structure 30 performs a precise printing operation on it, the processed first workpiece 210 continues to be carried by the first conveyor line 10 and conveyed to the lower station 500.

[0027] Both the first conveyor line 10 and the second conveyor line 20 transport the workpieces to the same unloading station 500. The unloading station 500 can be equipped with an unloading robot, which can easily pick up the first workpiece 210 and the second workpiece 220 together and send them to the subsequent lamination process. This makes the process from printing to lamination seamless and efficient, and eliminates the need for separate unloading terminals for the first workpiece 210 and the second workpiece 220, greatly saving space and equipment costs.

[0028] In some embodiments, the processing apparatus further includes a transfer structure 40 disposed between the first conveyor line 10 and the second conveyor line 20. The transfer structure 40 is used to receive the second workpiece 220 at the first conveyor line 10 and transfer the second workpiece 220 to the second conveyor line 20. The transfer structure 40 realizes the automatic transfer of the second target workpiece from the first conveyor line 10 to the second conveyor line 20, avoiding manual intervention, ensuring the accuracy of diversion and the high degree of automation of the production line, and significantly improving production efficiency.

[0029] In some embodiments, the transfer structure 40 is used to transfer the second workpiece 220 along the second direction b to move the second workpiece 220 to a position corresponding to one end of the second conveyor line 20. The transfer structure 40 is also used to transfer the second workpiece 220 along the first direction a to convey the second workpiece 220 to the second conveyor line 20. Understandably, after the transfer structure 40 moves into position along the second direction b, it synchronously transfers the workpiece 220 along the running direction of the second conveyor line 20, enabling the smooth placement of the second workpiece 220 onto the second conveyor line 20 in a dynamic manner. This effectively buffers the impact force during the transfer process, preventing the second workpiece 220 from being bumped, scratched, or broken, thus ensuring the yield rate of fragile products such as glass. The docking method of the transfer structure 40 and the second conveyor line 20 allows the transfer structure 40 and the second conveyor line 20 to complete the handover of the second workpiece 220 in synchronous motion. The second conveyor line 20 does not need to start and stop frequently for receiving materials, making the transition of the second workpiece 220 from the first conveyor line 10 to the second conveyor line 20 extremely smooth, eliminating the cycle time loss caused by poor docking, and further improving production efficiency.

[0030] In some embodiments, the transfer structure 40 includes a first frame 41, a plurality of first conveying rollers 42 disposed on the first frame 41, and a plurality of first conveyor belts 43 slidably disposed on the first frame 41 in a vertical direction. Each first conveyor belt 43 is respectively disposed between two adjacent first conveying rollers 42. Each first conveyor belt 43 is raised and lowered relative to each first conveying roller 42. The first conveying rollers 42 are used to convey the second workpiece 220 in a first direction a, and the first conveyor belts 43 are used to convey the second workpiece 220 in a second direction b.

[0031] Understandably, after the second workpiece 220 is transported from the first conveyor line 10 to the transfer station 300, the first conveyor belt 43 rises, extending beyond the surface of the first conveyor roller 42 to receive the second workpiece 220, and initiates lateral conveying along the second direction b, precisely moving the workpiece to correspond with the second conveyor line 20. Then, the first conveyor belt 43 descends, placing the second workpiece 220 onto the surface of the first conveyor roller 42. The first conveyor roller 42 rotates and conveys the second workpiece 220 along the first direction a, thereby transferring the second workpiece 220 to the second conveyor line 20. The entire process is smooth and rapid, achieving quick direction switching. Furthermore, the second workpiece 220 is always stably supported on the surface of the first conveyor roller 42 or the first conveyor belt 43, avoiding the risks of localized stress concentration, surface indentation, or accidental detachment that may occur when using grippers or suction cups. Moreover, the transfer structure 40 vertically stacks the two conveying functions, resulting in a very small footprint and compact structure, which is beneficial for miniaturization. Optionally, the first conveyor belt 43 can be connected to a lifting cylinder, which drives the first conveyor belt 43 to rise and fall.

[0032] In some embodiments, the first conveyor line 10 includes a second frame 11, a plurality of second conveyor rollers 12 disposed on the second frame 11, and a plurality of second conveyor belts 13 slidably disposed on the second frame 11 in a vertical direction. Each second conveyor belt 13 is respectively disposed between two adjacent second conveyor rollers 12. Each second conveyor belt 13 is raised and lowered relative to each second conveyor roller 12. The second conveyor rollers 12 are used to convey the first workpiece 210 or the second workpiece 220 in a first direction a, and the second conveyor belts 13 are used to convey the second workpiece 220 in a second direction b, so as to transfer the second workpiece 220 to the first conveyor belt 43.

[0033] Understandably, the second conveyor roller 12 is used to support and transport the first workpiece 210 and the second workpiece 220. After the second workpiece 220 is transported to the transfer station 300 by the second conveyor roller 12, the second conveyor belt 13 rises, raising the second workpiece 220 above the surface of the second conveyor roller 12, and initiating transverse transport along the second direction b, precisely transferring the second workpiece 220 to the first conveyor belt 43. The entire process is smooth and rapid, achieving quick direction switching, and the second workpiece 220 is always stably supported on the surface of the second conveyor roller 12 or the second conveyor belt 13, avoiding the risks of local stress concentration, surface indentation, or accidental detachment that may occur when using grippers or suction cups. Furthermore, the transfer structure 40 vertically stacks the two conveying functions, making the entire transfer structure 40 occupy a very small area and have a compact structure, which is conducive to miniaturization. Optionally, the second conveyor belt 13 can be connected to a lifting cylinder, which drives the second conveyor belt 13 to rise and fall.

[0034] In some embodiments, the processing apparatus further includes a buffer structure 50 for buffering the first workpiece 210, the buffer structure 50 being disposed between the transfer station 300 and the processing station 400; the buffer structure 50 includes a support frame 51 for supporting the first workpiece 210 and slidably disposed thereon, and a drive member 52 located above the support frame 51 for driving the support frame 51 to rise and fall; the first conveyor line 10 has a conveying surface for supporting the first workpiece 210, the conveying surface being provided with a clearance channel 14 for the support frame 51 to pass through; during the rising stroke, the support frame 51 lifts the first workpiece 210 conveyed by the first conveyor line 10 to a position away from the conveying surface, and during the falling stroke, the support frame 51 lowers the first workpiece 210 it carries back to the conveying surface.

[0035] Understandably, in continuous production, the cycle time of the previous process may not match that of the processing station 400. When the processing station 400 takes a long time due to program complexity, ink type change, or temporary malfunction, the buffer structure 50 ensures that the subsequent first workpiece 210 does not need to wait on the first conveyor line 10. Specifically, the support frame 51 of the buffer structure 50 rises under the action of the drive component 52, passes through the clearance channel 14, and lifts the first workpiece 210 that arrives later, removing it from the conveyor surface, thus achieving in-situ buffering. This allows the first conveyor line 10 to immediately free up a carrying position, and the next first workpiece 210 can be conveyed forward, ensuring the continuity of the conveying process. When the processing station 400 is ready, the support frame 51 descends, smoothly placing the buffered first workpiece 210 back onto the conveyor surface, and it continues to be conveyed to the processing station 400.

[0036] In this embodiment, the buffer structure 50 is integrated inside the first conveyor line 10, and the support frame 51 is raised and lowered via the clearance channel 14, eliminating the need for an additional parallel buffer conveyor line or a large buffer warehouse. This highly integrated design significantly saves on equipment footprint and manufacturing costs. Optionally, the drive component 52 is a lead screw and nut structure or a cylinder, with the drive end of the drive component 52 connected to the center of the top surface of the support frame 51.

[0037] In some embodiments, the support frame 51 includes support rods 511 for supporting the first workpiece 210. Multiple support rods 511 are spaced apart along a first direction a, and multiple clearance channels 14 are spaced apart along the first direction a, each clearance channel 14 being used for the passage of a particular support rod 511. The multiple support rods 511 provide comprehensive and balanced support to the entire bottom surface of the first workpiece 210, effectively preventing sagging, bending, or vibration of the middle of the first workpiece 210 due to insufficient support points. For workpieces with high rigidity but high brittleness, such as glass, this greatly reduces the risk of breakage or internal stress caused by uneven force during lifting, buffering, and lowering. Specifically, in the first conveyor line 10, clearance channels 14 are formed between adjacent second conveyor rollers 12.

[0038] In some embodiments, the first direction a and the second direction b are perpendicular to each other, and the first conveyor line 10 and the second conveyor line 20 are parallel to each other. After the second workpiece 220 is removed from the first conveyor line 10, it can enter the adjacent second conveyor line 20 via the shortest path, which helps to shorten the transfer time. At the unloading station 500, since the first conveyor line 10 and the second conveyor line 20 are parallel and their ends are aligned, the processed first workpiece 210 and the directly accessible second workpiece 220 can be easily joined together and picked up by the same unloading robot, which improves the convenience of the subsequent automated assembly process.

[0039] This utility model also proposes a glass production line, which includes a processing device. The specific structure of the processing device is as described in the above embodiments. Since this glass production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0040] In summary, the processing apparatus provided in this application embodiment, by setting up independent first conveyor line 10 and second conveyor line 20, allows the first conveyor line 10 to transport the first workpiece 210 to the processing structure 30 and unload the processed first workpiece 210, while the second conveyor line 20 directly unloads the second workpiece 220. This achieves the separation and parallel transport of the first workpiece 210 and the second workpiece 220. The second workpiece 220 does not need to wait for the first workpiece 210 to finish processing, but is directly and quickly transported to the unloading station 500 via the second conveyor line 20 for unloading. This eliminates the invalid waiting time caused by waiting for the processing of the first target workpiece in the prior art, which can significantly improve the production cycle of the processing apparatus and increase production efficiency. Furthermore, since the first workpiece 210 and the second workpiece 220 are transported to the same unloading station 500 for unloading, only one set of robotic arm or unloading platform is needed for unloading, which helps to reduce the space occupied by the processing apparatus.

[0041] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
