[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1 to 4 , which is the first embodiment of the present invention, and provides a clamping structure for laser cleaning equipment, including a rotating assembly 100, including a connecting block 101, a clamping jaw 102 rotatably connected to the connecting block 101, and a rotating shaft 103 provided inside the connecting block 101 for the clamping jaw 102 to rotate;

[0036] The rotating assembly 100 is provided with two groups;

[0037] The connecting assembly 200 includes a fixed block 201 hinged to the connecting block 101 and a moving block 202 capable of pulling the rotating assembly 100 closer to each other.

[0038] Among them, the fixed block 201 is hinged to two groups of rotating components, that is, the outer wall of the fixed block 201 is hinged to two connecting blocks 101, and each connecting block 101 is rotatably connected to a rotating shaft 103. When the two rotating shafts 103 collide with each other, the rotating shaft 103 starts to slide, so as to realize the rotation of the clamping jaw 102; the implementation method is, for example, a key is fixedly installed on the outer wall of the rotating shaft 103, and a spiral key groove is provided on the inner wall where the rotating shaft 103 and the connecting block 101 are in contact. When the rotating shaft 103 slides, the key on the outer wall of the rotating shaft 103 slides along the inside of the spiral key groove, and then drives the outer wall of the rotating shaft 103 to rotate. The clamping jaw 101 fixedly connected to the wall realizes rotation; for another example, the rotating shaft 103 and the connecting block 101 move linearly relative to each other, and the rotating shaft 103 is rotatably connected to the clamping jaw 102, wherein the key is fixed to the outer wall surface where the clamping jaw 102 and the rotating shaft 103 are in contact, and the spiral keyway is on the outer surface of the rotating shaft 103, and the spiral keyway is a spiral sliding groove, so that when the rotating shaft 103 moves linearly, the clamping jaw 102 can be forced to rotate; wherein the hinge connection between the connecting block 101 and the fixed block 201 can be a hinged rod of the prior art, that is, when the moving block 202 moves, the two connecting blocks 10 1 move closer to each other, realize the contact of the rotating shaft 103, and thus realize the rotation of the clamping jaw 102; the advantage of such a design is that when the moving block 202 moves, it will pull the two connecting blocks 101 closer to each other, rely on the friction between the clamping jaw 102 and the clamped object to clamp the object, and then lift the clamped object; this process can be realized by relying on the servo motor of the prior art. If the object is not clamped, or the object falls during the clamping process, the moving block 202 will continue to move, driving the two connecting blocks 101 closer to each other, so that the rotating shafts 103 move closer to each other, conflict with each other, and begin to produce The jaws 102 will slide and then rotate. At this time, if the clamped object falls, the jaws 102 will flip to ensure that the clamped object will not fall onto the original workstation and then enter the next process. At the same time, the clamped object can be pushed off the workstation to inform the operator that the object may be an unqualified workpiece. In addition, if the jaws 102 fail to clamp the object when they approach each other, the jaws 102 will start to flip along the upper surface of the workstation to ensure that nothing flows into the downward process of the workstation. At the same time, it also ensures that the clamped object may not be placed in place at the workstation to affect the clamping.

[0039] In summary, the things that need to be processed are placed in the production line. When the workstation is under the clamping structure used for laser cleaning equipment, the servo motor can be used to control the jaws 102 to fall, and then the motor can still be used to control the movement of the moving block 202. The moving block 202 drives the jaws 102 to move closer to each other and normally clamp the object on the workstation. Then the servo motor is used to clamp the object, flip it over or clamp it to the next process. When the clamping is loose or not clamped, the jaws 102 will flip over to clear the object on the workstation, ensuring that there are no objects on the workstation that enter the next process, and preventing the workpiece flowing to the next process from being processed due to clamping failure caused by the wrong position of the workpiece at the workstation, resulting in unqualified product processing.

[0040] Example 2

[0041] Reference Figures 1 to 4 , which is the second embodiment of the present invention, includes a first slide groove 101a provided inside the connecting block 101 for the rotating shaft 103 to slide; and an arc surface 101b provided on the outer wall of the connecting block 101 for the clamping claw 102 to slide.

[0042] Among them, the first slide groove 101a inside the connecting block 101 is a cylindrical channel, and one end extends out of the connecting block 101, so that the rotating shaft 103 can slide along the inside of the first slide groove 101a; the lower surface of the connecting block 101 and the clamping jaw 102 is processed with an arc, that is, an arc surface 101b that rotates and fits with the clamping jaw 102 is formed. The advantage of this design is that when the clamping jaw 102 rotates, it can rotate in accordance with the trajectory, providing support for the rotation of the clamping jaw 102.

[0043] The outer wall of the clamping jaw 102 is provided with a limit block 102a, and the limit block 102a can rotate around the outer wall of the rotating shaft 103;

[0044] The connecting block 101 is provided with a notch 101c for the limit block 102a to rotate;

[0045] A second sliding groove 103a is provided on the outer wall of the rotating shaft 103, and a sliding block 102a-1 which can slide along the inside of the second sliding groove 103a is provided on the outer wall of the limiting block 102.

[0046] Among them, a notch 101c is dug on the side of the connecting block 101 close to the clamping jaw 102, and the lateral length of the notch 101c is adapted to the lateral length of the limit block 102a, ensuring that the clamping jaw 102 can only rotate around the rotating shaft 103. At the same time, the second slide groove 103a is a spiral groove, that is, the second slide groove 103a spirals up along the surface of the rotating shaft 103. The advantage of this design is that when the rotating shaft 103 slides in a straight line along the inside of the first slide groove 101a, the slider 102a-1 will slide along the inside of the second slide groove 103a. Since the rotating shaft 103 cannot rotate, the rotating shaft 103 will push the clamping jaw 102 to rotate, and this rotation is a downward rotation.

[0047] A first elastic member 104 is disposed at the bottom of the first sliding groove 101 a , and one end of the first elastic member 104 is connected to the rotating shaft 103 .

[0048] Among them, one end of the first elastic member 103 is fixedly connected to the bottom of the first slide groove 101a, and the other end is fixedly connected to one end of the rotating shaft 103; and the first elastic member 103 is a deformable object such as a compression spring or an airbag. The advantage of such a design is that when the rotating shaft 103 slides to the bottom of the first slide groove 101a, it will squeeze the first elastic member 104. When the two rotating shafts 103 no longer conflict with each other, the first elastic member 104 releases potential energy, so that the clamping jaw 102 rotates back to its original position.

[0049] An end of the rotating shaft 103 away from the first elastic member 104 is hingedly connected to a contact plate 105 , and a second elastic member 106 is disposed between the contact plate 105 and the rotating shaft 103 .

[0050] Among them, the contact plate 105 and the rotating shaft 103 are connected by a ball head, and a second elastic member 106 is added between the contact plate 105 and the rotating shaft 103. The second elastic member 106 adopts an air bag. In this way, when the rotating shafts 103 are in contact, the contact plates 105 will squeeze each other, and the contact angle between the contact plates 105 can be appropriately adjusted to avoid the two rotating shafts 103 from colliding and getting stuck.

[0051] A first connecting rod 203 and a second connecting rod 204 are connected between the fixing block 201 and the connecting block 101;

[0052] The first connecting rod 203 and the moving block 202 are connected by a third connecting rod 205 .

[0053] The fixed block 201 and the connecting block 101 are connected by the first connecting rod 203 and the second connecting rod 204, and the two connecting rods 104 are used to realize hinge connection, which is more stable. At the same time, one end of the third connecting rod 205 is rotatably connected to the moving block 202, and the other end is rotatably connected to the middle part of the first connecting rod 203, so that when the moving block 202 moves, it can pull the first connecting rod 203 to rotate, and then make the clamping jaws 102 close to each other to achieve clamping.

[0054] In summary, when the object to be clamped moves to the top of the clamping structure used for the laser cleaning equipment, the motor is used to move the clamping structure to the position of the object to be clamped. Subsequently, the moving block 202 moves, and the third connecting rod 205 is used to pull the first connecting rod 204 to rotate, driving the connecting blocks 101 to approach each other. If the clamping jaws 102 can contact the outer surface of the object, then at this time, the abutment plate 105 will not contact. If the outer surface of the object is not clamped, the abutment plate 105 starts to contact, driving the clamping jaws 102 to flip, thereby completing the cleaning of the workstation.

[0055] Beneficial effect: It is ensured that when the clamping structure used for laser cleaning equipment does not clamp an object, it can ensure that no unprocessed object flows to the next workstation.

[0056] Example 3

[0057] Reference Figures 1 to 5 , which is the third embodiment of the present invention, further provides an all-round cleaning device. It includes a carrier 300, a tray 301 rotatably arranged on the surface of the carrier 300, a clamping structure for a laser cleaning device arranged on the surface of the carrier 300 close to the tray 301, and brackets 302 and a No. 1 laser cleaner 303 arranged on the outer wall of the bracket 302 are respectively arranged on both sides of the clamping structure for the laser cleaning device.

[0060] Among them, a lifting platform 304 is fixedly installed on the upper surface of the carrier 300, and a slide rail 304 is fixed on the side of the lifting platform 304 close to the tray 301. The mounting frame 305 can slide up and down along the surface of the slide rail 304, and this sliding can be achieved by a telescopic motor. At the same time, a rotating motor is installed on the surface of the mounting frame 305, and the output shaft of the rotating motor is fixedly connected to the clamping structure for the laser cleaning equipment; the rotation of the tray 301 is achieved by a servo motor. The main function of the carrier 300 is to provide space for laser cleaning and other electrical equipment, which is the prior art and will not be repeated here; a No. 1 laser cleaner 303 is installed on both sides of the clamping structure for the laser cleaning equipment, such as Figure 5As shown, the No. 1 laser cleaner 303 on the left first cleans the upper surface of the workpiece to be cleaned, and then the No. 2 laser cleaner 303 is used to clean the side of the workpiece. The clamping structure of the laser cleaning equipment clamps the workpiece to be cleaned, and then the workpiece is turned over and placed on the work station. The tray 301 is then rotated to transport the workpiece to the lower surface of the next No. 1 laser cleaner 303 to process the lower surface of the workpiece.

[0061] A second laser cleaner 306 is fixedly disposed on the surface of the carrier platform 300 close to the tray 301 and is placed vertically to the first laser cleaner 303 .

[0062] A No. 2 laser cleaner 306 is installed on the left side of the No. 1 laser cleaner 303 on the left side. The cleaning direction of the No. 2 laser cleaner 306 is the side of the workpiece, and the side is cleaned.

[0063] A work station 307 is provided on the surface of the tray 301 .

[0064] A small motor is provided below the workstation 307 to enable the workstation 307 to rotate.

After the cleaning is completed, the tray 301 is rotated continuously to move the cleaned workpiece to the next position, i.e., the position of the second laser cleaner (306). The rotation is then stopped. The side of the workpiece is then cleaned. The tray 301 is rotated continuously to move the workpiece to the bottom of the clamping structure, and the clamping structure flips the workpiece. The tray 301 is then rotated to move the workpiece to the bottom of the clamping structure. Figure 5 Below the No. 1 laser cleaner 303 on the middle right side, the workpiece is then cleaned, the tray 301 is rotated again, and then the workpiece cleaning is completed, the material is unloaded, and the next process flow is entered.
