[0046] The present invention will be further described in detail below with reference to specific embodiments.

[0047] Example:

[0048] like Figure 1 and Figure 2As shown, a frame cutting device 100 of this utility model includes a frame 1, a roller assembly 2, a removal assembly 3, a first sawing assembly 4a, a second sawing assembly 4b, a receiving assembly 5, and a waste discharge conveyor 6. A pair of X-direction slide rails 11 are provided at the lower part of the frame 1. The roller assembly 2 is located on the X-direction feeding side of the middle layer of the frame 1, with its axis along the Y-direction. The removal assembly 3 is located on the X-direction discharge side of the roller assembly 2. The first sawing assembly 4a is located between the removal assembly 3 and the roller assembly 2 and saws along the Y-direction. The second sawing assembly 4b is located on the X-direction discharge side of the removal assembly 3 and saws along the Y-direction. Both the first sawing assembly 4a and the second sawing assembly 4b are adjustablely mounted on the X-direction slide rails 11. The waste discharge conveyor 6 is located at the lower part of the frame 1 and conveys waste along the X-direction. The two X-direction slide rails 11 are located on opposite sides of the waste discharge conveyor 6 along the Y-direction. The first sawing assembly 4a, the second sawing assembly 4b, and the removal assembly 3 all straddle the waste discharge conveyor belt 6. The removal assembly 5 is located on the upper part of the frame 1 and pulls the head of the frame profile 200 from above the support roller assembly 2 to above the second sawing assembly 4b. The X and Y directions are both located in the horizontal plane and are perpendicular to each other.

[0049] The frame profile 200 is fed into the frame cutting device 100 along the X direction. The insertion component 5 clamps the head of the frame profile 200 and pulls the front section of the frame profile 200 to the processing area (the area between the first sawing component 4a and the second sawing component 4b). During the pulling process, the support roller component 2 temporarily supports the middle or rear section of the frame profile 200, allowing it to move smoothly. The removal component 3 supports the middle section of the frame profile 200 during sawing to prevent it from sagging; after sawing is completed, the frame is removed from the processing area by the removal component 3 to avoid affecting continuous processing. The first sawing component 4a and the second sawing component 4b are used to cut the front and rear ends of the frame profile 200 at 45° angles. The waste discharge conveyor 6 is actually located below the processing area, so the waste cut from the frame profile 200 by the first sawing component 4a and the second sawing component 4b falls directly onto the waste discharge conveyor 6 and is then transported to one side for collection. This equipment can not only complete the end sawing of the 200mm frame profile, but also automatically complete the loading and unloading work, which improves the level of automation, saves manpower, and increases work efficiency.

[0050] Both the first sawing assembly 4a and the second sawing assembly 4b include a sawing mechanism 41 that makes 45° cuts along the Y direction and a clamping mechanism 42 located above the sawing mechanism 41. A transfer claw 43, a chip blowing pipe 44, and a discharge assembly 7 are provided on the same Y-direction side of both sawing mechanisms 41. The chip blowing pipe 44 blows air along the X direction. When the side frame is on the transfer claw 43, the air outlet direction of the chip blowing pipe 44 is towards the end of the side frame. The discharge assembly 7 includes a side push drive 71, a second Z-direction drive 72 driven by the side push drive 71 to move along the Y direction, and a discharge claw 73 driven by the second Z-direction drive 72 to move along the Z direction. The Z direction is vertical.

[0051] The first sawing assembly 4a and the second sawing assembly 4b use the sawing mechanism 41 to saw the ends of the frame profile 200 at a 45° angle in the Y direction. During sawing, two clamping mechanisms 42 are used to press the two ends of the frame profile 200 against the tables of the first sawing assembly 4a and the second sawing assembly 4b respectively, thereby preventing the frame profile 200 from deviating from its position when subjected to sawing force. The intermediate support claw 43 serves as a temporary storage and cleaning position after the frame is sawn. The X-direction distance between the first sawing assembly 4a and the second sawing assembly 4b can be adjusted along the X-direction slide rail 11, thereby allowing for quick switching between cutting different lengths of frame. Because the intermediate support claw 43 moves with either the first sawing assembly 4a or the second sawing assembly 4b, the distance between the two intermediate support claws 43 can also automatically adapt to the processing length of the frame. After sawing, the two ends of the frame are cut surfaces, and there may be debris on the cut surfaces. When the removed component 3 transfers the cut frame to the transfer claw 43, the two transfer claws 43 can lift up both ends of the frame, so that the two ends of the frame are aligned with the chip blowing pipe 44. In this way, the chip blowing pipe 44 can blow away the debris to prevent it from affecting the framing of the photovoltaic module.

[0052] like Figure 4 and Figure 5 As shown, the removal assembly 3 includes a gantry frame 31, a Y-axis translation module 32 disposed on the upper part of the gantry frame 31, a connecting bracket 33 driven by the Y-axis translation module 32, two first Z-axis driving members 34 disposed at both ends of the connecting bracket 33 in the X direction, and removal claws 35 driven to rise and fall by the first Z-axis driving members 34. Each removal claw 35 is provided with two slots 351 of the same shape, and one side of the bottom of the slot 351 is higher than the other side.

[0053] Because the right-angled edge of the frame profile 200 needs to be horizontal during sawing, the first sawing component 4a and the second sawing component 4b can cut 45° angles at both ends of the frame using their respective sawing mechanisms 41. Since the lower part of the frame profile 200 is not flat at this time, the bottom of the groove 351 must be designed with one side higher than the other. After sawing, the removal claw 35 will first rise to lift the frame, then move it horizontally to the Y-direction side, and then lower it to place the frame elsewhere. Here, "elsewhere" can refer to the transfer bracket 42, or to various conveying mechanisms that remove the frame from the frame cutting equipment 100, such as roller conveying mechanisms. Because frames of the same length are always used in pairs, this equipment preferably feeds two frame profiles 200 together. This speeds up processing efficiency and ensures that the two frame profiles 200 processed each time are of equal length, with a single frame cutting cycle of less than 2 seconds. Theoretically, the number of grooves 351 can be an even number of two or more. The number of slots on the transfer bracket 42 and the number of slots on the removal claw 35 must be equal to the number of slots 351.

[0054] like Figure 5 and Figure 7 As shown, the roller assembly 2 includes two variable diameter rollers 21 with a common Y-axis and a blocking roller 22. The variable diameter rollers 21 are thicker on one side and thinner on the other side, forming two limiting channels with the blocking roller 22 that match the structure of the groove 351.

[0055] One limiting channel is formed by the variable-diameter support roller 21 closer to the blocking roller 22 and the blocking roller 22, while the other limiting channel is formed by two blocking rollers 22. To ensure that the frame profile 200 moves horizontally along the X-direction with its right-angled side horizontal, both the support groove 351 and the limiting channels are designed with a structure where one side is higher than the other. In this embodiment, the support groove 351 is provided with two adjustable bolts 36, one high and one low, which can accommodate the structures of various frame profiles 200. In practical applications, the bottom of the support groove 351 can also be designed as an integral structure with one side higher than the other.

[0056] like Figure 6 and Figure 7 As shown, the insertion component 5 includes a clamping mechanism 51 that clamps the frame profile 200 along the Y direction, a third Z-direction drive member 52 that drives the clamping mechanism 51 to move up and down along the Z direction, and an X-direction translation module 53 that drives the third Z-direction drive member 52 to move along the Y direction. The X-direction translation module 53 directly drives a vertical plate 54. The third Z-direction drive member 52 is located on the front of the vertical plate 54 and drives a movable bracket 55 that slides along the Z direction. The clamping mechanism 51 is located at the lower part of the movable bracket 55.

[0057] On the feeding side, a section of the frame profile 200 is always supported by the roller assembly 2. The clamping mechanism 51 clamps the suspended portion of the front section of the frame profile 200 from the feeding position of the roller assembly 2. Then, the third Z-axis drive 52 raises the clamping mechanism 51 above the height of the roller assembly 2. Then, the X-axis translation module 53 moves the clamping mechanism 51 to a higher position, thereby pulling the head of the frame profile 200 all the way to above the second sawing assembly 4b. Here, the X-axis translation module 53 uses a synchronous belt translation mechanism. The clamping mechanism 42 does not interfere with the movement of the clamping mechanism 51 and the frame profile 200. At the end of the movement, the tail of the frame profile 200 will detach from the roller assembly 2, but the middle part will fall onto the ejector claw 35. Then, the clamping mechanism 51 releases the frame profile 200, and the first and second ends of the frame profile 200 can fall onto the first sawing assembly 4a and the second sawing assembly 4b respectively.

[0058] like Figure 8 and Figure 9 As shown, the lower part of the movable bracket 55 is provided with a pair of Y-direction slide rails 56. The clamping mechanism 51 includes a pair of clamping blocks 511 that slide along the Y-direction slide rails 56, a linkage gear 512 that is rotatably disposed on the lower part of the movable bracket 55 along the Z-axis, and a Y-direction driving member 513 disposed on the movable bracket 55 and driving one of its clamping blocks 511 to move along the Y-direction. Each clamping block 511 includes several chucks 5111 and a rack 5112. The chucks 5111 on the two clamping blocks 511 are opposite to each other, and the two racks 5112 are respectively meshed with the X-direction sides of the linkage gear 512.

[0059] The clamping block 511 clamps the Y-direction sides of the frame profile 200 by means of the chucks 5111, which provide a number of independent clamping points. In this embodiment, each clamping block 511 is provided with four chucks 5111, and every two chucks 5111 abut against the same side of a frame profile 200. There are a total of four pairs of chucks 5111 on the two clamping blocks 511, and two pairs of chucks 5111 clamp one frame profile 200, so a total of two frame profiles 200 can be clamped. The engagement relationship between the rack 5112 and the linkage gear 512 enables the two clamping blocks 511 to maintain synchronous reverse movement in the Y direction under the drive of a Y-direction drive member 513. The center of symmetry of each pair of chucks 5111 does not change, and this center of symmetry is located within the aforementioned limiting channel, so the clamping block 511 can always clamp the frame profile 200 from the support roller assembly 2.

[0060] The working process of this border cutting device 100 is as follows:

[0061] 1. The upstream equipment supplies two frame profiles 200 along the X direction to the frame cutting equipment 100. The head of the frame profile 200 rests on two variable diameter support rollers 21 to prevent the head of the frame profile 200 from drooping.

[0062] 2. The X-axis translation module 53 drives the clamping mechanism 51 to translate above the roller assembly 2. The third Z-axis drive unit 52 controls the clamping mechanism 51 to descend and clamp the front section of the two side profiles 200 along the Y-axis from a position close to the roller assembly 2. Then the clamping mechanism 51 lifts up with the head of the side profile 200, thus moving past the roller assembly 2 and translating all the way to above the second sawing assembly 4b. Then the clamping mechanism 51 releases the two side profiles 200, so that their heads fall on the table of the second sawing assembly 4b. At this time, the tail of the side profile 200 is located on the table of the first sawing assembly 4a.

[0063] 3. The insertion component 5 is reset to wait for the next pair of frame profiles 200 to be clamped. The two clamping mechanisms 42 press down the two ends of the frame profiles 200. Then the two sawing mechanisms 41 start to move along the Y direction and make 45° sawing at both ends of the frame profiles 200 to obtain the frame. The waste falls onto the waste discharge belt 6 below and is collected.

[0064] 4. The clamping mechanism 42 releases the sawn frame, the first Z-axis drive 34 drives the ejector claw 35 to rise, thereby raising the frame. Then the Y-axis translation module 32 moves the frame to the top of the transfer claw 43, the ejector claw 35 descends, the frame is left on the transfer claw 43, the chip blowing pipe 44 blows air to the end of the frame to clean up the debris, and the ejector claw 35 resets along the Y direction.

[0065] 5. The second Z-axis drive member 72 drives the discharge claw 73 to rise, thereby allowing the frame to detach from the transfer claw 43. Then, the side push drive member 71 drives the discharge claw 73 to move along the Y-axis above the discharge conveying mechanism. The discharge claw 73 descends, and the frame is left on the discharge conveying mechanism. The discharge conveying mechanism moves the frame out of the frame cutting device 100, and the discharge claw 73 resets along the Y-axis.

[0066] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
