Description

Technical Field

[0001] This utility model relates to a laminated frame production equipment, and more particularly to an automatic milling equipment for structurally optimized laminated frames. Background Technology

[0002] Double-glass solar photovoltaic panels require a lamination process during production. To prevent the glass sheets from shifting during lamination, a lamination frame is introduced as a positioning fixture. A typical lamination frame is a rectangular metal frame with a thickness similar to that of the double-glass photovoltaic panel module. The internal space of the lamination frame can accommodate the double-glass photovoltaic panel module. The outer surface of the lamination frame is usually wrapped with Teflon fiberglass tape, which has good lubrication and anti-adhesion properties, preventing the adhesive on the double-glass photovoltaic panel module from sticking to the lamination frame during lamination.

[0003] Conventional laminated frames typically require welding four metal plates together to form a frame, followed by grinding and polishing of the welded areas. This manufacturing process is unsuitable for small-scale automated production, and therefore currently relies mainly on manual labor, limiting production efficiency and yield. To address this, the applicant has developed a weld-free laminated frame (see attached document). Figure 1 It consists of two long rods, two short rods, and four right-angled pieces. The long and short rods are made of metal, while the right-angled pieces are made of high-strength engineering plastic. They are assembled using snap-fit ​​joints, and the assembly points can be reinforced with glue. The ends of the metal parts need to be machined to fit with the right-angled pieces, specifically requiring milling and drilling processes. To improve the efficiency and accuracy of milling and drilling, an automated machining equipment for this product needs to be developed. Summary of the Invention

[0004] This invention provides an automated milling machine for structurally optimized laminated frames, solving the problem in the prior art that newly developed laminated frames require corresponding automated machining equipment.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an automatic milling equipment for structure-optimized laminated frames, comprising: a water platform, on which two horizontally parallel first guide rails and a first linear servo module parallel to the first guide rails are provided;

[0006] Two sliding clamping seats are provided. Each sliding clamping seat consists of a slider slidably mounted on the first guide rail, a base fixed on the slider, a fixed clamping block fixed on the base, a movable clamping block, and a clamping cylinder. The clamping cylinder is fixed on the base, and the movable clamping block is fixed on the telescopic rod of the clamping cylinder. A connecting rod is fixedly connected between the two sliding clamping seats, and the connecting rod is synchronously connected to the moving seat of the first linear servo module.

[0007] Two drilling modules are symmetrically arranged on a water platform outside the two first guide rails. Each module includes a second linear servo module that is vertically fixed relative to the water platform, a lifting seat, and a drilling machine that is vertically mounted on the lifting seat. The lifting seat is fixedly connected to the moving seat of the second linear servo module.

[0008] Two sets of first milling modules are symmetrically arranged on a water platform outside the two first guide rails, including a first mounting base fixed on the water platform and a first milling machine unit vertically mounted on the first mounting base;

[0009] Two sets of second milling modules are symmetrically arranged on a water platform outside the two first guide rails. Each module includes a second mounting base fixed on the water platform, a third linear servo module horizontally fixed on the second mounting base, a horizontal moving base, and a second milling machine unit vertically mounted on the horizontal moving base. The distribution axis of the third linear servo module is set at an acute angle to the first linear servo module.

[0010] By controlling the extension and retraction of the clamping cylinder, the movable clamping block can be moved synchronously. The fixed clamping block and the movable clamping block on the sliding clamping seat can be used to clamp and fix the rod to be processed. The two sliding clamping seats are used together to clamp and fix the rod to be processed. The first linear servo module can drive the rod to be processed to reciprocate along the first guide rail. The processing steps of this utility model are as follows: Loading: The rod to be processed is placed on two sliding clamping seats and fixed in the center; Drilling: The first linear servo module drives the two sliding clamping seats to move to the drilling station. At this time, both ends of the rod are below the two drilling modules. The second linear servo module drives the rotating drilling unit to descend and drill holes at both ends of the rod; Length milling: The first linear servo module drives the two sliding clamping seats to move at a constant speed through the length milling station. The milling cutter of the first milling unit is in a rotating state. After the two ends of the rod pass through the first milling unit, the excess length at both ends will be milled off, and the length of the rod at this time is the final length; Grooving: The first linear servo module drives the two sliding clamping seats to move to the grooving station. The third linear servo module drives the rotating second milling unit to feed towards both ends of the rod, and triangular grooves can be milled on the upper surface of both ends of the rod. At this time, the rod machining is completed. The first linear servo module drives the two sliding clamping seats to return to the loading station and removes the processed rod.

[0011] Furthermore, the drilling module also includes a support plate, several guide posts that slide through the platform, a base plate fixedly connected to the lower end of the guide posts, and a return spring sleeved on the guide posts. The return spring is connected between the base plate and the bottom surface of the platform. A control motor is provided on one side of the support plate, and a height control wheel is fixed on the output shaft of the control motor. The height control wheel has a cut surface, and the bottom of the support plate abuts against the top of the height control wheel. A through hole is also provided on the support plate. Under the action of the return spring, the support plate tends to move downward. Since the outer contour of the height control wheel is not a complete circle, the height of the support plate can be controlled by controlling the position of the cut surface on the height control wheel. When the rod has not moved to the drilling position, the cut surface of the height control wheel faces upward, and the support plate is in a low position. When the rod is in the drilling position, the circular surface of the height control wheel faces upward, and the support plate is in a high position, just abutting against the bottom surface of the rod. This way, when drilling, the rod is supported by a bearing plate underneath, preventing complete deformation and ensuring high drilling accuracy.

[0012] Furthermore, a sensor for detecting the position of the sliding clamping seat is installed on the water platform, located on both the front and rear sides of the first milling module. The sensor is either a proximity sensor or a photoelectric sensor. The function of the sensor is to sense the position of the sliding clamping seat. When the sliding clamping seat has not entered the length milling station, the first milling module can be stopped to reduce power consumption.

[0013] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model can automatically perform drilling and milling processes on rods, and by adding a length milling station, the drilling accuracy, milling accuracy and rod length of the rods have extremely high machining accuracy, which greatly improves machining efficiency and accuracy.

[0028] By controlling the extension and retraction of the clamping cylinder, the movable clamping block can be moved synchronously. The fixed clamping block and the movable clamping block on the sliding clamping seat can be used to clamp and fix the rod to be processed 100. The two sliding clamping seats are used together to clamp and fix the rod to be processed. The first linear servo module can drive the rod to be processed to reciprocate along the first guide rail. The processing steps of this embodiment are as follows: loading, placing the rod to be processed on the fixed clamping block on the two sliding clamping seats, the positioning baffle is located on one side of the loading station, and one end of the rod abuts against the positioning baffle. At this time, the rod is basically centered. Then the clamping cylinder extends, and the rod is clamped and fixed between the movable clamping block and the limiting part; drilling, the first linear servo module drives the two sliding clamping seats to move to the drilling station. At this time, the two ends of the rod are located below the two drilling modules.
