Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and in particular to a clamping structure for laser cleaning equipment and an all-around cleaning device. Background Technology

[0002] In the field of parts cleaning, there are various cleaning methods such as mechanical cleaning, chemical cleaning, ultrasonic cleaning, and laser cleaning. Among them, laser cleaning is characterized by its environmental friendliness, high cleaning efficiency, good cleaning effect, and ease of operation. Currently, for the laser cleaning of disc-shaped parts, most methods use handheld laser cleaning machines or general benchtop laser cleaning equipment. When using a handheld laser cleaning machine to clean disc parts, workers manually control the laser's cleaning path on the parts to remove contaminants or excess substances. This requires a high level of skill from the operator and also suffers from problems such as low cleaning efficiency and poor operational precision and consistency. Conventional benchtop laser cleaning equipment is equipped with a laser head, and the laser cleaning path is controlled by a program, resulting in high precision. However, when used for disc parts that require omnidirectional cleaning, the position of the disc parts needs to be constantly adjusted manually, resulting in wasted time and low cleaning efficiency.

[0013] As a preferred embodiment of the clamping structure of the present invention for laser cleaning equipment, wherein: a first elastic element is provided at the bottom of the first slide groove, and one end of the first elastic element is connected to the rotating shaft.

[0014] As a preferred embodiment of the clamping structure of the present invention for laser cleaning equipment, wherein: the end of the rotating shaft away from the first elastic element is hinged to an abutment plate, and a second elastic element is provided between the abutment plate and the rotating shaft.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0034] Example 1

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

[0036] The rotating assembly 100 is provided in two sets;

[0037] The connecting component 200 includes a fixed block 201 hinged to the connecting block 101 and a movable block 202 that pulls the rotating component 100 closer together.

[0038] The fixed block 201 is hinged to two sets of rotating components, specifically two connecting blocks 101 are hinged to the outer wall of the fixed block 201. Each connecting block 101 has a rotating shaft 103 rotatably connected inside. When the two rotating shafts 103 abut against each other, the rotating shafts 103 begin to slide, thereby causing the gripper 102 to rotate. One possible implementation is to fix a key on the outer wall of the rotating shaft 103 and provide a spiral keyway on the inner wall where the rotating shaft 103 fits with the connecting block 101. When the rotating shaft 103 slides, the key on the outer wall of the rotating shaft 103 slides along the spiral keyway, thus driving the rotating shaft 103 to rotate. The gripper 101, which is fixedly connected to the wall, can rotate; for 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 gripper 102. A key is fixed to the outer wall surface where the gripper 102 and the rotating shaft 103 meet, and a spiral keyway is on the outer surface of the rotating shaft 103. The spiral keyway is a spiral-shaped groove, so that when the rotating shaft 103 moves linearly, it can force the gripper 102 to rotate; the hinge between the connecting block 101 and the fixed block 201 can be a hinge rod of existing technology, which can enable the two connecting blocks 101 to move when the moving block 202 moves. The two connecting blocks 101 move closer together, bringing the rotating shaft 103 into contact, thus enabling the gripper 102 to rotate. The advantage of this design is that as the moving block 202 moves, it pulls the two connecting blocks 101 closer together, using the friction between the gripper 102 and the object to hold it, and then lifting the object. This process can be achieved using a servo motor, a technology already available. If the object is not held, or if it falls during the gripping process, the moving block 202 will continue to move, causing the two connecting blocks 101 to move closer together, thus bringing the rotating shaft 103 closer together and causing them to come into contact, initiating production. The object slides, causing the gripper 102 to rotate. If the object falls, the rotation of the gripper 102 ensures that the object does not fall back to its original position before proceeding to the next step. At the same time, it can also push the object off the workstation, informing the operator that the object may be a defective workpiece. In addition, if the gripper 102 fails to grip an object when it comes together, it will start to rotate along the upper surface of the workstation to ensure that nothing flows down the workstation. It also ensures that there may be instances where the object is not properly positioned, affecting the gripping.

[0039] In summary, when the workpiece to be processed is placed on the production line, and the workstation reaches the clamping structure used by the laser cleaning equipment, the servo motor controls the gripper 102 to fall. Subsequently, the motor can still control the moving block 202 to move, causing the gripper 102 to move closer together and normally clamp the object on the workstation. Then, the servo motor clamps the object, flips it, or clamps it to the next process. If the clamping becomes loose or not clamped, the gripper 102 will flip to remove the object from the workstation, ensuring that no object enters the next process. This also prevents the workpiece from flowing to the next process due to incorrect workpiece positioning, thus avoiding the situation where the workpiece is not processed and the product is defective.

[0040] Example 2

[0041] Reference Figures 1-4 The second embodiment of the present invention includes a first sliding groove 101a inside the connecting block 101 for the rotating shaft 103 to slide; and an arc surface 101b on the outer wall of the connecting block 101 for the gripper 102 to slide.

[0042] The first groove 101a inside the connecting block 101 is a cylindrical channel, with one end extending out of the connecting block 101, so that the rotating shaft 103 can slide along the inside of the first groove 101a. The lower surface of the contact surface between the connecting block 101 and the gripper 102 is rounded, forming an arc surface 101b that rotates and fits with the gripper 102. The advantage of this design is that when the gripper 102 rotates, it can fit the trajectory and rotate, providing support for the rotation of the gripper 102.

[0043] The outer wall of the gripper 102 is provided with a limiting block 102a, which rotates around the outer wall of the rotating shaft 103;

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

[0045] The outer wall of the rotating shaft 103 is provided with a second sliding groove 103a, and the outer wall of the limiting block 102a is provided with a slider 102a-1 that slides along the inside of the second sliding groove 103a.

[0046] Specifically, a notch 101c is cut into the side of the connecting block 101 near the gripper 102. The lateral length of the notch 101c is adapted to the lateral length of the limiting block 102a, ensuring that the gripper 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 upward along the surface of the rotating shaft 103. The advantage of this design is that when the rotating shaft 103 slides linearly 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 gripper 102 to rotate, and this rotation is a downward rotation.

[0047] The bottom of the first slide groove 101a is provided with a first elastic element 104, and one end of the first elastic element 104 is connected to the rotating shaft 103.

[0048] One end of the first elastic element 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. The first elastic element 103 is a deformable object such as a compression spring or an airbag. The advantage of this design is that when the rotating shaft 103 slides towards the bottom of the first slide groove 101a, it will squeeze the first elastic element 104. When the two rotating shafts 103 no longer collide, the first elastic element 104 releases potential energy, causing the gripper 102 to rotate back to its original position.

[0049] A contact plate 105 is hinged to one end of the rotating shaft 103 away from the first elastic member 104, and a second elastic member 106 is provided between the contact plate 105 and the rotating shaft 103.

[0050] The contact plate 105 and the rotating shaft 103 are connected by a ball joint, and a second elastic element 106 is added between the contact plate 105 and the rotating shaft 103. This second elastic element 106 is an air bladder. When the rotating shaft 103 contacts, the contact plates 105 will squeeze each other, and the contact angle between the contact plates 105 can be adjusted appropriately to avoid the two rotating shafts 103 from hitting 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 link 203 and the moving block 202 are connected by the third link 205.

[0053] The fixed block 201 and the connecting block 101 are connected by a first connecting rod 203 and a second connecting rod 204, which are hinged together for greater stability. Meanwhile, 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. When the moving block 202 moves, it pulls the first connecting rod 203 to rotate, causing the grippers 102 to come together and clamp the object.

[0054] In summary, when the object to be clamped moves above the clamping structure of the laser cleaning equipment, the motor moves the clamping structure to the position of the object to be clamped. Then, the moving block 202 moves, and the third link 205 pulls the first link 204 to rotate, causing the connecting blocks 101 to move closer to each other. If the gripper 102 can contact the outer surface of the object, then the contact plate 105 will not contact. If it does not clamp the outer surface of the object, then the contact plate 105 will start to contact, causing the gripper 102 to flip, thus cleaning the workstation.

[0055] Beneficial effect: Ensures that the clamping structure used in laser cleaning equipment can prevent unprocessed objects from flowing to the next station when no object is clamped.

[0056] Example 3

[0057] Reference Figures 1-5 This is the third embodiment of the present invention, which further provides an all-around cleaning device. It includes a support platform 300, a tray 301 rotatably disposed on the surface of the support platform 300, and a clamping structure for laser cleaning equipment disposed on the surface of the support platform 300 near the tray 301. The clamping structure for laser cleaning equipment is provided with brackets 302 on both sides and a first laser cleaner 303 disposed on the outer wall of the brackets 302.

[0058] A lifting platform 304 for moving the clamping structure of the laser cleaning equipment is fixedly provided on the surface of the support platform 300 near the tray 301;

[0059] The outer wall of the lifting platform 304 is provided with a slide rail 304a, and a mounting frame 305 is connected to the surface of the slide rail 304a, and the mounting frame 305 is fixedly connected to the fixing block 201.

[0060] A lifting platform 304 is fixedly installed on the upper surface of the support platform 300. A slide rail 304 is fixed to one side of the lifting platform 304 near the tray 301. The mounting frame 305 can slide up and down along the surface of the slide rail 304. This sliding is achieved by a telescopic motor. Simultaneously, a rotary motor is installed on the surface of the mounting frame 305, and the output shaft of the rotary 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 support platform 300 is to provide space for laser cleaning and other electrical equipment; this is existing technology and will not be elaborated further. A laser cleaner 303 is installed on each side of the clamping structure for the laser cleaning equipment. Figure 5 As shown, the first laser cleaner 303 on the left first cleans the upper surface of the workpiece to be cleaned, and then the second laser cleaner 303 cleans the side of the workpiece. The clamping structure of the laser cleaning equipment clamps the workpiece to be cleaned, and then flips the workpiece and puts it on the work station. Then the tray 301 is rotated to transport the workpiece to the lower surface of the next first laser cleaner 303 for processing.

[0061] A second laser cleaner 306 is fixedly mounted on the surface of the support platform 300 near the tray 301, which is perpendicular to the first laser cleaner 303.

[0062] A second laser cleaner 306 is installed to the left of the first laser cleaner 303 on the left. The cleaning direction of the second laser cleaner 306 is the side of the workpiece, and the side is cleaned.

[0063] The surface of pallet 301 is provided with workstation 307.

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

[0065] like Figure 5 The servo motor connected to tray 301 is started, which drives station 307 to rotate, transporting the workpiece on station 307 to... Figure 5 Below the first laser cleaner 303 on the left side, the rotation stops. The first laser cleaner 303 begins to clean the upper surface of the workpiece on the surface of station 307. After completion, the tray 301 continues to rotate, moving the cleaned workpiece to the next position, namely the position of the second laser cleaner (306). Then, the rotation stops, and the side of the workpiece is cleaned. The tray 301 continues to rotate, moving the workpiece to below the clamping structure, allowing the clamping structure to flip the workpiece. Then, the tray 301 is rotated to transport the workpiece to the next position. Figure 5 Below the No. 1 laser cleaner 303 on the right side, the workpiece is then cleaned. The tray 301 is rotated again, and the workpiece cleaning is then completed. The workpiece is unloaded and proceeds to the next process step.
