[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0046] During the production of profiles, burrs are easily generated at the end fracture points. Related technologies typically use manual methods to remove these burrs, which often results in incomplete removal or the burrs being squeezed into the inner cavity of the profile during operation, leading to assembly deviations and making precise installation difficult.

[0047] To address the aforementioned problems, this application provides a profile processing apparatus. The apparatus includes a frame and a grinding mechanism mounted on the frame. The grinding mechanism includes a slide, a clamping device, a grinding device, and a rotating device. The slide is mounted on the frame and is movable relative to the frame along a first direction parallel to the horizontal direction. The clamping device is rotatably mounted on the slide and is used to clamp the profile, the extension direction of which is parallel to the first direction. The grinding device is mounted on the slide and is used to grind the profile. The rotating device is drively connected to the clamping device and drives the clamping device to rotate, thereby rotating the profile held by the clamping device from a first position to a second position. This allows the grinding device to grind profiles in different positions, improving the burr removal effect.

[0048] An exemplary embodiment of this application discloses a profile processing apparatus, referring to... Figures 1-7 The profile processing device includes a frame 1 and a grinding mechanism 2 disposed on the frame 1. The grinding mechanism 2 is used to grind the profile 3.

[0049] The grinding mechanism 2 includes a slide 21, a clamping device 22, a grinding device 23, and a rotating device 24.

[0050] The slide 21 is disposed on the frame 1 and can move relative to the frame 1 in a first direction, which is parallel to the horizontal direction.

[0051] The clamping device 22 is rotatably mounted on the slide 21. The clamping device 22 is used to clamp the profile 3, and the extension direction of the profile 3 is parallel to the first direction. The slide 21 can drive the clamping device 22 to move along the first direction so as to fit the profile 3 into the clamping device 22.

[0052] The grinding device 23 is disposed on the slide 21. The grinding device 23 is used to grind the profile 3. When the slide 21 moves along the first direction, it can drive the grinding device 23 to move synchronously. The grinding device 23 is driven by the slide 21 to approach the profile 3 to grind the end of the profile 3.

[0053] The rotating device 24 is connected to the clamping device 22 in a transmission manner. The rotating device 24 is used to drive the clamping device 22 to rotate so as to rotate the profile 3 clamped by the clamping device 22 from the first position state to the second position state.

[0054] In this embodiment, when the profile 3 is in the first position, the slide 21 moves along the first direction to drive the grinding device 23 and the clamping device 22 to move along the first direction, so that the grinding device 23 can approach the end of the profile 3 and grind the end of the profile 3. The rotating device 24 drives the clamping device 22 to rotate, so that the profile 3 held by the clamping device 22 is rotated from the first position to the second position. Then, the grinding device 23 grinds the end of the profile 3 in the second position, thereby realizing all-round grinding of the end of the profile 3. There is no need for manual adjustment of the posture of the profile 3, which greatly improves the automation of the processing, significantly reduces the time cost of process switching, and improves the overall grinding processing efficiency. The movement of the slide 21 along the first direction can fit the profile 3 into the clamping device 22, reducing processing errors and safety hazards caused by human operation errors.

[0055] In some embodiments, see Figures 1-7 The rotating device 24 includes a first drive motor 241, a first gear 242, and a second gear 243. The first drive motor 241 is fixed to the slide 21. When the slide 21 moves in a first direction, it can drive the first drive motor 241 to move synchronously. The first gear 242 is connected to the output shaft of the first drive motor 241. The second gear 243 is connected to the first gear 242 through external meshing transmission. The second gear 243 is connected to the clamping device 22, and the clamping device 22 can rotate synchronously with the second gear 243. The first drive motor 241 is used to drive the first gear 242 to drive the second gear 243 to rotate, and the rotation of the second gear 243 drives the clamping device 22 to rotate.

[0056] In this embodiment, the clamping device 22 can rotate synchronously with the second gear 243. By controlling the forward and reverse rotation and the rotation angle of the first drive motor 241, the profile 3 can be adjusted from the first position state to the second position state to perform grinding on the profile 3 in different position states. This achieves all-round grinding of the end of the profile 3 and improves the grinding effect on the burrs on the profile 3. For example, by controlling the clamping device 22 to rotate 90°, the profile 3 can be rotated from the first position state to the second position state.

[0057] In some embodiments, see Figures 1-7 The clamping device 22 includes a limiting sleeve 221 and at least two clamping blocks 222. The limiting sleeve 221 is a hollow cylindrical structure. A bearing 25 is sleeved on the outside of the limiting sleeve 221. The limiting sleeve 221 is rotatably mounted on the slide table 21 through the bearing 25. The axial direction of the limiting sleeve 221 is parallel to the first direction so that the profile 3 can be inserted into the interior of the limiting sleeve 221.

[0058] At least two clamping blocks 222 are spaced apart along the circumference of the limiting sleeve 221 on the inner wall of the limiting sleeve 221. The at least two clamping blocks 222 together enclose a clamping space 223 for the insertion of the profile 3. The profile 3 located in the clamping space 223 abuts against each clamping block 222 to clamp the profile 3. The clamping block 222 includes a guide slope 2221, which abuts against the profile 3 and is inclined relative to the first direction. When the profile 3 has not yet entered the clamping space 223, the guide slope 2221 extends from the end near the profile 3 toward the direction away from the profile 3 and toward the center of the clamping space 223, so as to guide the profile 3 when it enters the clamping space 223, thereby guiding the profile 3 to the center of the clamping space 223 and fixing it with the clamping block 222. This ensures that when the clamping device 22 drives the profile 3 to rotate, the profile 3 is still in the center of the clamping space 223, ensuring that the position of the profile 3 will not shift, thereby improving the accuracy and grinding effect of the grinding device 23 on the end of the profile 3. For example, there may be three clamping blocks 222, and the guide slope 2221 may be an arc surface or a plane.

[0059] In this embodiment, at least two clamping blocks 222 are provided inside the limiting sleeve 221 to improve the clamping and fixing effect on the profile 3. The limiting sleeve 221 is rotated by the rotating device 24. The limiting blocks inside the limiting sleeve 221 limit the profile 3 and drive the profile 3 to rotate synchronously, so as to rotate the profile 3 from the first position state to the second position state. This makes it easier for the grinding device 23 to grind the ends of the profile 3 in different position states, thereby improving the grinding efficiency of burrs.

[0060] In some embodiments, the bearing 25 includes an inner sleeve and an outer sleeve. The inner sleeve is rotatable relative to the outer sleeve and is connected to a limiting sleeve 221. The outer sleeve is connected to a slide 21. By configuring the bearing 25 so that the limiting sleeve 221 can rotate relative to the slide 21, the profile 3 inside the slide 21 can be rotated from a first position state to a second position state, thereby improving the grinding effect of the profile 3.

[0061] In some embodiments, see Figures 1-5The grinding mechanism 2 also includes a dust collection box 26, which is connected to the slide table 21. The dust collection box 26 has a dust collection chamber 261 inside, and the grinding brush 231 of the grinding device 23 is disposed in the dust collection chamber 261. The clamping space 223 is connected to the dust collection box 26 so that the grinding end 31 of the profile 3 can extend into the dust collection chamber 261. The dust collection box 26 can collect the dust and debris after grinding by the grinding device 23 in the grinding box to prevent dust and debris from splashing. The dust collection box 26 is provided with a suction port 262 that is connected to the dust collection chamber 261. The suction port 262 is connected to a dust suction device, which is used to suck out the dust and debris in the dust collection box 26 to prevent the profile 3 from being secondary contaminated by dust and debris after grinding.

[0062] In some embodiments, see Figures 3-4 The grinding device 23 includes a grinding brush 231 and a second drive motor 232. The grinding brush 231 is disposed in the dust collection chamber 261, and its rotation grinds the end of the profile 3. The slide 21 has a through hole, and the second drive motor 232 is fixed to the bottom of the slide 21 and located outside the dust collection chamber 261. The output shaft of the second drive motor 232 passes through the through hole to connect with the grinding brush 231. The second drive motor 232 drives the grinding brush 231 to rotate, thereby grinding the grinding end 31 of the profile 3 that extends into the dust collection chamber 261. The slide 21 slides in a first direction, which drives the second drive motor 232 and the grinding brush 231 to move synchronously, thereby realizing automated grinding of the profile 3, improving grinding accuracy, and avoiding the problem of incomplete manual grinding.

[0063] In some embodiments, see Figures 1-4 The frame 1 is equipped with a slide rail 27, which extends along a first direction. A slide table 21 is connected to the slide rail 27, and the slide rail 27 guides the slide table 21, allowing the slide table 21 to move along the extension direction of the slide rail 27. The grinding mechanism 2 also includes a first cylinder 28. The first cylinder 28 is fixed to the frame 1, and its drive end is connected to the slide table 21. The drive end of the first cylinder 28 can extend and retract along the first direction. The first cylinder drives the slide table 21 to slide along the slide rail 27, thereby driving the grinding device 23 mounted on the slide table 21 to move synchronously along the first direction to grind the end of the profile 3.

[0064] In some embodiments, see Figure 1 The frame 1 is equipped with two grinding mechanisms 2, which are arranged opposite each other along the first direction so as to grind both ends of the profile 3 in the length direction at the same time, thereby improving the grinding efficiency of burrs on the profile 3.

[0065] In some embodiments, see Figure 5The grinding mechanism 2 also includes a fixing part 29 and a second cylinder 2101. The fixing part 29 is used to fix the profile 3. The second cylinder 2101 is fixed to the frame 1, and the driving end of the second cylinder 2101 is connected to the fixing part 29. The driving end of the second cylinder 2101 can extend and retract in a second direction. The second cylinder 2101 is used to drive the fixing part 29 to move in the second direction to adjust the height of the fixing part 29 in the second direction, wherein the second direction is perpendicular to the first direction. By driving the fixing part 29 to move in the second direction through the second cylinder 2101, when the grinding device 23 grinds the end of the profile 3, the fixing part 29 is extended by the second cylinder 2101, and the fixing part 29 clamps the profile 3 to improve the stability of the profile 3 during grinding, avoid the profile 3 from moving, and thus improve the grinding quality of the profile 3.

[0066] In some embodiments, see Figure 5 The fixing part 29 includes a fixing base 291, a first clamping claw 292, and a second clamping claw 293. Along the second direction, the fixing base 291 includes a first surface and a second surface facing away from each other. The first surface is connected to the drive end of the second cylinder, and the second surface is provided with a sliding groove 294. The extension direction of the sliding groove 294 is parallel to the horizontal plane and perpendicular to the first direction. Both the first clamping claw 292 and the second clamping claw 293 are disposed within the sliding groove 294. When the profile 3 needs to be fixed, the second cylinder 2101 drives the fixing part 29 to move towards the profile 3. The first clamping claw 292 and the second clamping claw 293 move towards each other within the sliding groove 294 to clamp the profile 3, improving the stability of the profile 3 during grinding and preventing the profile 3 from shifting, thereby improving the grinding quality of the profile 3. When it is necessary to rotate the profile 3 from the first position to the second position, the first jaw 292 and the second jaw 293 move in opposite directions within the slide groove 294 to release the profile 3. The second cylinder 2101 drives the fixing part 29 to move away from the profile 3 to release the restriction on the profile 3. At this time, the rotating device 24 drives the clamping device 22 to rotate, so as to rotate the profile 3 held by the clamping device 22 from the first position to the second position, so that the grinding device 23 can grind the profile 3 in different positions respectively, thereby improving the grinding effect of the profile 3 and improving the grinding efficiency of burrs. For example, the first jaw 292 is connected to a third cylinder, which is used to drive the first jaw 292 to extend and retract along the extension direction of the slide groove 294. The second jaw 293 is connected to a fourth cylinder, which is used to drive the second jaw 293 to extend and retract along the extension direction of the slide groove 294.

[0067] In some embodiments, see Figure 4The slide plate 21 includes a first slide plate 211 and a second slide plate 212. The first slide plate 211 and the second slide plate 212 are set at an angle. For example, the plane of the first slide plate 211 is parallel to the horizontal plane, and the plane of the second slide plate 212 is perpendicular to the horizontal plane. The first slide plate 211 and the second slide plate 212 are set perpendicular to each other. The first slide plate 211 is slidably connected to the slide rail 27. The bearing 25 is disposed on the second slide plate 212, and the limiting sleeve 221 is rotatably connected to the second slide plate 212 through the bearing 25.

[0068] In some embodiments, the slide 21 and the slide cover can be integrally formed to reduce assembly errors between components and improve assembly accuracy.

[0069] In some embodiments, see Figure 1 The grinding mechanism 2 also includes a protective cover 2102, which is placed outside the rotating device 24. The protective cover 2102 can shield the second gear 243 to prevent mechanical injury to the user when the exposed second gear 243 rotates.

[0070] In some embodiments, the profile may be, for example, a photovoltaic frame.
