Technical Field

[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a positioning fixture and laser processing equipment. Background Technology

[0002] Most existing laser processing positioning devices can only be adapted to workpieces of a single size and cannot be flexibly adjusted to meet the positioning requirements of workpieces of different sizes. This limitation means that when dealing with processing tasks involving workpieces of various sizes, it is necessary to frequently change the positioning device or readjust the equipment parameters, which not only increases production costs but also reduces production efficiency. Utility Model Content

The first positioning surface and the second positioning surface are both perpendicular to the bearing surface. The first positioning surface and the second positioning surface intersect to form a triangular positioning notch. The bearing surface is used to support the workpiece, and the workpiece protrudes outward from the bearing surface.

[0006] A pushing component is used to push the workpiece within the positioning notch so that the sidewall of the workpiece abuts against the first positioning surface and the second positioning surface, thereby achieving the positioning of the workpiece.

[0029] Please see Figure 1 and Figure 2 The positioning fixture provided in the embodiments of this application will now be described. The positioning fixture provided in the embodiments of this application includes a positioning component 1 and a pushing component 2.

[0030] The positioning component 1 includes a positioning element 11, which has a plurality of positioning notches 111 for positioning workpieces. The positioning element 11 has a first positioning surface 1111, a second positioning surface 1112, and a bearing surface 1113. The first positioning surface 1111 and the second positioning surface 1112 are both perpendicular to the bearing surface 1113. The first positioning surface 1111 and the second positioning surface 1112 intersect to form a triangular positioning notch 111. The bearing surface 1113 is used to support the workpiece, and the workpiece protrudes outward from the bearing surface 1113.

[0031] The pushing component 2 is used to push the workpiece in the positioning notch 111 so that the side wall of the workpiece abuts against the first positioning surface 1111 and the second positioning surface 1112 to achieve the positioning of the workpiece.

[0032] The workpiece in this application embodiment can be a cylindrical battery casing, a battery cell or a battery, or other workpieces that need to be positioned and processed.

[0033] The pushing component 2 can be a cylinder, an electric push rod, or other similar driving device. For example, the pushing component 2 uses a cylinder, where the piston rod of the cylinder contacts the workpiece. Through the extension and retraction of the cylinder, the workpiece is pushed to move inward toward the positioning notch 111 until the sidewall of the workpiece is tightly fitted with the first positioning surface 1111 and the second positioning surface 1112.

[0034] When positioning the workpiece, the workpiece to be processed is placed on the bearing surface 1113 of the positioning component 1, with the outer surface of the workpiece protruding from the bearing surface 1113. The pushing component 2 is activated, pushing the workpiece towards the inside of the positioning notch 111. During this movement, the sidewall of the workpiece gradually contacts the first positioning surface 1111 and the second positioning surface 1112, eventually fitting tightly together. At this point, the workpiece is precisely positioned within the positioning notch 111.

[0035] After positioning is complete, laser processing is performed on the workpiece. Because the workpiece has been precisely positioned, the accuracy and consistency of laser processing are effectively guaranteed.

[0036] After processing is completed, push component 2 to reset and release the workpiece. The processed workpiece can be taken out from the positioning notch 111 for subsequent operations.

[0037] The positioning notch 111 is triangular in shape, and workpieces of various sizes can be placed inside it. Therefore, the positioning fixture can be adapted to workpieces of various sizes without the need to frequently change the positioning device or readjust the equipment parameters, which not only reduces production costs but also improves production efficiency.

[0038] Preferably, the angle between the first positioning surface 1111 and the second positioning surface 1112 is an obtuse angle.

[0039] The angle between the first positioning surface 1111 and the second positioning surface 1112 is an obtuse angle, which allows for the placement of larger workpieces and prevents the angle from being too small, which would only be suitable for smaller workpieces. The obtuse angle design improves the adaptability of the positioning fixture.

[0040] Preferably, the angle between the first positioning surface 1111 and the second positioning surface 1112 is 110°.

[0041] When the angle between the first positioning surface 1111 and the second positioning surface 1112 is greater than 110°, smaller workpieces may experience inaccurate positioning. When the angle between the first positioning surface 1111 and the second positioning surface 1112 is less than 110°, larger workpieces may have difficulty fitting into the positioning notch 111. A 110° angle between the first positioning surface 1111 and the second positioning surface 1112 provides the widest range of workpiece sizes that can be accommodated.

[0042] The positioning notch 111 also includes an arc transition surface 1114, which is disposed between the first positioning surface 1111 and the second positioning surface 1112. The arc transition surface 1114 is used to abut against the side wall of the workpiece.

[0043] When the side of the workpiece is curved, the arc transition surface 1114 can abut against the side of the workpiece to increase the contact area with the workpiece, so as to provide better support and improve the stability of the workpiece after positioning.

[0044] The heights of the first positioning surface 1111, the second positioning surface 1112, and the arc transition surface 1114 are all lower than the height of the workpiece machining area. In other words, the workpiece machining area is exposed outside the positioning fixture to prevent obstruction of the workpiece machining area. Thus, after the workpiece is positioned, it is convenient for external machining devices to process the workpiece.

[0045] The positioning component 1 also includes several adsorption elements 12, which are disposed at the positioning notch 111.

[0046] The adsorption element 12 prevents the workpiece from tipping over during the pushing process of the pushing component 2, and the adsorption element 12 improves the stability of the workpiece positioning.

[0047] The adsorption element 12 can specifically be a suction hole provided on the bearing surface 1113 of the positioning notch 111, which generates negative pressure by being connected to a vacuum generator (such as a vacuum pump), thereby adsorbing the workpiece. The suction hole adsorbs the workpiece within the positioning notch 111 through negative pressure. The number and position of the suction holes can be adjusted according to the shape and size of the workpiece to ensure sufficient adsorption force.

[0048] The adsorption element 12 can also be a permanent magnet or an electromagnet. Permanent magnets and electromagnets are suitable for adsorbing metal workpieces, especially ferromagnetic materials (such as iron and steel).

[0049] The electromagnet uses an electric current to generate a magnetic field to attract workpieces. The electromagnet contacts the surface of the workpiece, and the magnetic field generated by the electric current attracts the workpiece into the positioning notch 111. The attraction force of the electromagnet can be controlled by adjusting the current to accommodate workpieces of different sizes and weights.

[0050] The pushing component 2 includes a driving member 21 and a pushing block 22. The driving member 21 is connected to the pushing block 22 in a transmission manner to drive the pushing block 22 to move closer to or away from the workpiece in the positioning notch 111.

[0051] The drive component 21 in this embodiment can employ various types of power sources, such as electric motors, cylinders, or hydraulic cylinders. In this embodiment, the drive component 21 is an electric actuator. This electric actuator has stable thrust output and precise stroke control capability, enabling precise extension and retraction movements according to a preset program or control signal.

[0052] The push block 22 can be a plate-like or block-like structure with a contact surface adapted to the shape of the workpiece. In this embodiment, the push block 22 adopts a plate-like structure so as to push multiple workpieces simultaneously. The contact surface can be a plane, an arc surface, or other shapes to accommodate workpieces of different shapes.

[0053] The pushing component 2 also includes a buffer 23, which is disposed on the side of the pushing block 22 that contacts the workpiece.

[0054] A buffer 23 is disposed on the side of the push block 22 that contacts the workpiece, providing cushioning when the push block 22 contacts the workpiece, reducing damage to the workpiece from impact. In this embodiment, the buffer 23 is a layer of elastic material, such as rubber, polyurethane foam, or silicone. This elastic material layer is fixed to the push block 22 by means of adhesion, snap-fit, or embedding. The thickness of the buffer 23 can be adjusted according to the material of the workpiece and the pushing requirements to ensure that sufficient cushioning is provided without affecting the pushing accuracy of the push block 22.

[0055] The positioning fixture also includes a rotary table 3, which is used to place several positioning components 1 and pushing components 2.

[0056] The rotary table 3 is a circular or polygonal platform structure. Its bottom is mounted on the base of the equipment via a rotating shaft and is driven to rotate by a drive device. The surface of the rotary table 3 has several mounting positions evenly distributed, each mounting position for placing a positioning component 1 and a pushing component 2.

[0057] The rotation of the rotary worktable 3 allows the external processing device to perform batch processing on the workpieces on the positioning assembly 1, thereby improving work efficiency.

[0058] The rotary worktable 3 is equipped with a wire adapter 31, which is used to prevent the wire from getting tangled during rotation.

[0059] The wiring adapter 31 is located near the rotation axis of the rotary table 3 and is used to connect the wiring of the positioning component 1 and the pushing component 2 on the rotary table 3, such as power lines, signal lines, and air pipes. The function of the wiring adapter 31 is to prevent these wires from getting tangled during the rotation of the rotary table 3 and to ensure that the wiring remains unobstructed at all times.

[0060] In this embodiment, the line adapter 31 is specifically a gas-electric hybrid slip ring or an opto-electric combined slip ring. Both types of slip rings can transmit power, signals, and gas simultaneously, meeting the requirements of the positioning fixture for transmitting multiple media during rotation.

[0061] A gas-electric hybrid slip ring is a slip ring that integrates electrical and gas transmission functions. It achieves synchronous transmission of electricity and gas through an internal conductive ring and gas channel. In this embodiment, the electrical part of the gas-electric hybrid slip ring is used to transmit power and control signals, while the gas part is used to transmit compressed air, such as the air source for pneumatic actuators. The conductive ring of the gas-electric hybrid slip ring is made of a highly conductive material to ensure the stability and reliability of power transmission; the gas channel employs a sealed design to prevent gas leakage.

[0062] An opto-electric combined slip ring is a slip ring that integrates optical fiber transmission, electrical transmission, and gas transmission functions. It achieves synchronous transmission of optical signals, power, and gas through internal optical fiber channels, conductive rings, and gas channels. In this embodiment, the optical fiber portion of the opto-electric combined slip ring is used to transmit high-speed data signals (e.g., signals for sensors or cameras), the electrical portion is used to transmit power and control signals, and the gas portion is used to transmit compressed air. The optical fiber channel of the opto-electric combined slip ring uses low-loss optical fiber to ensure the stability and high speed of optical signal transmission; the design of the conductive ring and gas channel is similar to that of a gas-electric hybrid slip ring to ensure the reliability of power and gas transmission.

[0063] This application also provides a laser processing device, including the positioning fixture described above.

[0064] The laser processing equipment of this application includes the positioning fixture in any of the above embodiments, and therefore has the beneficial effects brought by the positioning fixture in any of the above embodiments, which will not be repeated here.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
