[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] Example:

[0031] This embodiment introduces the structure of a laser engraving jig.

[0032] Reference Figure 1 , 2 , 3, Figure 1 This is a three-dimensional structural schematic diagram of a laser engraving fixture of the utility model. Figure 2 This is a schematic diagram of the disassembled feeding device in a laser engraving jig. Figure 3 It is a schematic diagram of a pin hole 2 in a feeding device in a laser engraving jig.

[0033] A laser engraving jig comprises: a feeding device 1 and a discharging device 2, wherein the discharging device 2 is placed in the feeding device 1, and the feeding device 1 comprises a loading hopper 11 and a bracket 15, wherein the bracket 15 is movably connected to the rotating hopper 11, and by shaking the feeding device 1, a product 26 is allowed to move freely in the feeding device 1 and fill the cavity of the discharging device 2; a positioning device is arranged in the discharging device 2.

[0034] The charging hopper 11 is provided with a cavity 12 for placing the discharge device 2. The cavity 12 for placing the discharge device is designed with a sliding structure so that the operator can easily install and take out the discharge device.

[0035] Furthermore, a bracket rotation hole 17 is provided on the bracket 15, and a hopper rotation hole 13 is provided on the charging hopper 11. The bracket 15 and the charging hopper 11 are movably connected via a rotating shaft 16 that passes through the bracket rotation hole 17 and the hopper rotation hole 13 respectively.

[0036] Furthermore, a second latch hole 24 is provided below the charging hopper 11 to correspond to the first latch hole 20 on the rotating shaft 16, and the middle shaft 19 passes through the second latch hole 111 and the first latch hole 161 to achieve the connection between the rotating shaft 16 and the charging hopper 11; a shaft head 162 is provided at one end of the rotating shaft 16. In this embodiment, the shaft head and the latch hole are reserved so that a motor can be pre-installed to electrically shake the rotating shaft when necessary.

[0037] Furthermore, a socket is provided at one end of the central axis 19, and the latch 191 is passed through the socket to achieve fixation. Before the end of the central axis 19 passing through the latch hole 161 and the latch hole 2 111 is fixed, a gasket 21 is sleeved to enhance the stability of the connection.

[0038] Furthermore, a shockproof cotton 18 is attached to the contact point between the bracket 15 and the loading hopper 11, which has a shock-absorbing effect when shaking and can prevent the product from falling out of the hopper. In this embodiment, the shockproof cotton is 38° EVA shockproof cotton.

[0039] Reference Figure 4 , 5 As shown, Figure 4 This is a schematic diagram of the disassembly of a discharge device in a laser engraving jig. Figure 5 The schematic diagram of the top view of the discharge device from the perspective of the laser engraving machine working lens is shown in FIG. The discharge device 2 includes a square fixture base 21, and the structural dimensions of the fixture base are calculated and designed based on the circumscribed circle of the laser engraving machine working lens diameter. This design greatly improves the utilization space of the fixture and the maximum discharge quantity, and can also fully exert the operation effect of the laser engraving machine in one engraving process, thereby improving production efficiency.

[0040] Furthermore, the fixture base 21 is provided with a U-shaped groove 211, and a positioning block 212 is provided on the U-shaped groove 211, and a U-shaped PIN is placed in the U-shaped groove 211. The positioning block is located in the U-shaped groove and is a convex design. The convex point size and the product tolerance are designed according to 6g, which can effectively control the direction of the product. When the direction is wrong, the product will swing out of the U-shaped groove of the discharge device with the help of the feeding device.

[0041] In this embodiment, the inventor designs the U-shaped PIN, L-piece and U-shaped groove all according to a 3° draft angle, and the size matching tolerance is H7 / m6. The tight-fitting installation eliminates the need for threaded fixation, making the assembly method more convenient and preventing the product from being stuck.

[0042] Furthermore, a positioning hole 213 and a threaded hole 214 are provided on the jig base 21, and an L-piece 23 is correspondingly connected to the jig base 21, and a screw introduction hole 232 is provided on the L-piece 23. The screw 24 passes through the screw introduction hole 232 and the threaded hole 214 in sequence to fix the L-piece on the jig base 21.

[0043] In this embodiment, the number of the positioning holes 213 is four, and the four positioning holes are designed as through holes only on the fixture base; only a screw introduction hole 232 is opened on the L-piece, and no other openings are opened. In this way, after the discharge device is installed, the product is prevented from falling into the hole and affecting the efficiency of the discharge device in the laser engraving fixture cavity.

[0044] Furthermore, the discharge device 2 is provided with a second handle 25 , and the second handle 25 is fixed to the L-piece 23 by the screw 24 passing through the screw introduction hole 232 .

[0045] like Figure 6 As shown, Figure 6 It is a schematic diagram of the coordination between the loading hopper and the bracket in a laser engraving fixture. In this embodiment, the inventor designs the loading hopper 11 as a conical structure with a cone angle of 30°. When in use, the operator puts the discharge device 2 into the feeding device 1, puts in about 2Kpcs of products, and then shakes the feeding device to make it move left and right within a range of 30°, so that the products can move freely in the device. The discharge device can be covered by swinging about 5 to 10 times. Before taking out the discharge device, the discharge device is first swung to one side, and the product falls to the bottom of one side of the discharge device. Then, the discharge device is taken out and placed on the workbench to perform the laser engraving operation. The operation process can be completed by one person, saving labor costs.

[0046] The laser engraving jig introduced in this embodiment has a simple structure and adopts a split design, which improves the ease of processing. By calculating the jig base according to the circumscribed circle of the diameter of the working objective lens of the laser engraving machine, a cube structure is obtained, which maximizes the discharge of the laser engraving area, improves production efficiency, and saves manpower. Through the cooperation of the feeding device and the discharge device, fast and convenient free discharge can be achieved, and the position accuracy of the product discharge can be ensured. The decomposable structure of the jig makes it easy to change from outsourced engraving / discharge machining to in-factory wire-cut machining. The jig can be applied to a variety of products and can be processed by wire-cut machining, which can save the cost of jig processing.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
