Description

Technical Field

[0001] This utility model relates to a conveying device, specifically a segmented double-row clamping conveying device. Background Technology

[0002] For glass laser drilling machines, the glass sheet needs to be transported to the drilling device by a conveying mechanism so that the drilling position of the glass sheet is aligned with the laser head of the drilling device before the drilling operation is carried out.

[0003] Chinese utility model patent CN222922478U discloses a clamping-type precision positioning conveying mechanism, including a frame, a conveyor belt mechanism, and a conveying drive mechanism. Both the conveyor belt mechanism and the conveying drive mechanism are mounted on the frame, and the conveyor belt mechanism is connected to the power output end of the conveying drive mechanism. The mechanism is characterized by: the conveyor belt mechanism comprising a first conveyor belt mechanism and a second conveyor belt mechanism; the clamping-type precision positioning conveying mechanism further comprising a conveying adjustment mechanism, a front clamping assembly, and a rear clamping assembly; the conveying adjustment mechanism is mounted on the frame, with the first and second conveyor belt mechanisms mounted side-by-side on the adjustment end of the conveying adjustment mechanism, which drives the first and second conveyor belt mechanisms to move laterally in opposite or opposite directions; the front clamping assembly comprises two front clamping members, respectively located at the front ends of the first and second conveyor belt mechanisms; the rear clamping assembly comprises two rear clamping members, respectively located at the rear ends of the first and second conveyor belt mechanisms. During operation, this clamping-type precision positioning conveyor mechanism transports glass sheets from front to back via a first and second conveyor belt mechanism. A conveyor adjustment mechanism then drives the first and second conveyor belt mechanisms to move laterally in opposite directions. When moving towards each other, the glass sheet, placed flat between the two conveyor belt mechanisms, is clamped and fixed on both sides. When moving in opposite directions, the glass sheet is slightly loosened, allowing it to move back and forth and its position to be finely adjusted, ensuring precise alignment of the drilling position with the laser head. However, this clamping-type precision positioning conveyor mechanism uses an integral conveying structure and lacks segmented adjustment functionality. It cannot adjust the position of the glass sheet in the front-to-back direction. When multi-station continuous operation is required (such as immediate chamfering after drilling), the chamfering process and the drilling process often have a mismatch in cycle time, easily wasting production time and affecting the working efficiency of the glass laser drilling machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a segmented double-row clamping and conveying device. This segmented double-row clamping and conveying device has a segmented adjustment function, which can adjust the position of different glass sheets in the front-to-back direction during the conveying process. It is suitable for multi-station continuous operation of glass laser drilling machines and can improve work efficiency. The technical solution adopted is as follows:

[0005] A segmented double-row clamping conveyor includes a frame, two conveyor bases arranged side-by-side, a conveyor adjustment mechanism for adjusting the position of the two conveyor bases in the left-right direction, two conveyor belt mechanisms, and two clamping assemblies. The two conveyor bases are mounted on the frame via the conveyor adjustment mechanism. The two conveyor belt mechanisms and the two clamping assemblies correspond one-to-one with the two conveyor bases. The two conveyor belt mechanisms are respectively mounted on their respective conveyor bases and arranged side-by-side. The two clamping assemblies are respectively mounted on their respective conveyor bases and arranged side-by-side. The two clamping assemblies are located on both sides of the two conveyor belt mechanisms. The conveyor belt mechanism includes a front conveyor belt, a rear conveyor belt, and a transition conveyor belt. The rear conveyor belt is located directly behind the front conveyor belt, and its front end is connected to the rear end of the front conveyor belt. The transition conveyor belt is located on one side of the front and rear conveyor belts. The top surface of the front section of the transition conveyor belt is flush with the top surface of the rear section of the front conveyor belt, and the top surface of the rear section of the transition conveyor belt is flush with the top surface of the front section of the rear conveyor belt.

[0006] In this manual, "front" and "back" refer to the following directions along the glass sheet conveying direction: the first to arrive is considered "front," and the last to arrive is considered "back."

[0007] When the aforementioned segmented double-row clamping and conveying device is applied to a glass laser drilling machine, the laser drilling device of the glass laser drilling machine is positioned directly above the two front conveyor belts, and the glass hole chamfering device of the glass laser drilling machine is positioned directly above the two rear conveyor belts. During operation, the two conveyor belt mechanisms transport multiple glass sheets (the glass sheets are placed horizontally, with both sides of the glass sheet resting flat on the two conveyor belt mechanisms) from front to back, allowing them to pass sequentially through the drilling station and the chamfering station. The two front conveyor belts transport the glass sheets to the drilling station of the laser drilling device and then pause. The conveying adjustment mechanism adjusts the two conveyor bases to move closer together, causing the two clamping components to clamp and position the glass sheet from both sides. The laser drilling device then performs laser drilling on the glass sheet, forming a glass hole. (With the cooperation of the two front conveyor belts and the conveying adjustment mechanism, when the glass sheet is released, it can be conveyed back and forth; when the glass sheet is tightened again, it can be...) (Repositioning allows for continuous drilling of multiple holes in the front and back directions of a single piece of glass); two transition conveyor belts are used to transfer the glass sheet from the two front conveyor belts to the two rear conveyor belts, effectively increasing the contact area between the two conveyor belt mechanisms and the glass sheet, effectively preventing it from jumping during the transfer from the two front conveyor belts to the two rear conveyor belts, thereby improving the stability of its conveying; the two rear conveyor belts are used to transport the glass sheet to the chamfering station of the glass hole chamfering device and then pause their movement. The conveying adjustment mechanism adjusts the two conveying bases to move closer to each other, driving the two clamping components to clamp and position the glass sheet from both sides. Then, the glass hole chamfering device mechanically chamfers the edges of the glass holes on the glass sheet. This segmented double-row clamping and conveying device has a segmented adjustment function. The front and rear conveyor belts of the two conveyor belt mechanisms operate independently, and can respectively transport the glass sheets on them to the drilling station and the chamfering station to cooperate with the laser drilling device and the glass hole chamfering device to complete the laser drilling and glass hole chamfering processes respectively. It is suitable for multi-station continuous operation of glass laser drilling machines. It can solve the problem of mismatch between the chamfering process and the drilling process during the conveying process, effectively reduce the waste of production time, and thus improve the working efficiency of glass laser drilling machines.

At least one first guide sleeve is installed on the conveying base, and the first guide sleeve is sleeved on the corresponding guide rod. When the conveying adjustment mechanism needs to adjust the position of the two conveying bases in the left-right direction, the adjusting motor drives the adjusting screw to rotate in the forward or reverse direction. Utilizing the meshing relationship between the two adjusting nuts and the two threaded segments of the adjusting screw, and coordinating the guiding movement between the guide rod and the first guide sleeve, the two conveying bases and their conveyor belt mechanisms can be moved towards or away from each other via the two adjusting nuts.
