DETAILED DESCRIPTION
[0034] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0035] In order to illustrate the technical solution of the present utility model, specific embodiments are provided below for illustration.
[0036] like Figures 1 to 8 As shown, a jig 100 for laser marking of a device according to an embodiment of the utility model can accurately locate the position of the device. The jig 100 includes a base plate 110, and the base plate 110 is used to support the device. The base plate 110 is constructed as a rectangular plate structure for supporting multiple devices. The device is placed on the base plate 110. The base plate 110 is provided with a positioning groove 111, and the shape of the positioning groove 111 matches the shape of the device. The positioning groove 111 is used to place the device. In this way, precise positioning is possible. Among them, the device is a semiconductor device, for example, it can be a butterfly semiconductor laser or other suitable semiconductor devices. Of course, the device can also be a non-semiconductor device, which is not limited here.
[0037] like Figure 3As shown, the base plate 110 includes an upper surface 112, and the upper surface 112 of the base plate 110 faces the device. The positioning groove 111 is recessed downward from the upper surface 112 of the base plate 110. The opening direction of the positioning groove 111 is open upward along the thickness direction of the base plate 110. The device is placed in the positioning groove 111, and the positioning groove 111 can limit the shaking of the device, and will not cause the device to produce angle and position deviation, thereby not causing laser marking errors. The device can be marked by a laser marking machine. The laser marking machine is a movable mechanical structure driven by a dual-coordinate motor that can move in both a first direction D1 and a second direction D2. The first direction D1 can be a Y-axis direction, and the second direction D2 can be an X-axis direction. In this embodiment, the first direction D1 is parallel to the length direction of the base plate 110, and the second direction D2 is parallel to the width direction of the base plate 110. The laser marking machine can use visual positioning software to control the movement of the motor, take pictures and locate the coordinates of the marking workpiece, and then perform the marking operation after positioning, and perform the marking operation in a horizontal and then vertical manner.
[0038] The fixture 100 further includes a positioning plate 130, which is connected to the bottom plate 110. The positioning plate 130 and the bottom plate 110 can be connected together by integral molding. For example, the positioning plate 130 and the bottom plate 110 can be integrally molded by injection molding. Optionally, the positioning plate 130 and the bottom plate 110 can also be connected together by welding. The positioning plate 130 is connected to the upper surface 112 of the bottom plate 110. Figure 5 As shown, the positioning plate 130 protrudes from the bottom plate 110. The positioning plate 130 protrudes from the bottom plate 110 along the thickness direction of the bottom plate 110. The positioning plate 130 protrudes upward along the thickness direction of the bottom plate 110. Preferably, the positioning plate 130 protrudes from the upper surface 112 of the bottom plate 110.
[0039] Return now Figure 3 , the positioning plate 130 is used to position the device. The positioning plate 130 is provided with a groove 131, and the groove 131 is used to place the wire of the device. The groove 131 is recessed downward from the upper surface of the positioning plate 130. The position of the groove 131 corresponds to the position of the positioning groove 111. The groove 131 passes through the positioning plate 130 along the first direction D1. The first direction D1 is perpendicular to the length direction of the positioning plate 130. The position of the groove 131 corresponds to the position of the device. The groove 131 corresponds to the equipment along the first direction D1. The groove 131 is used to place the wire of the device. The wire of the device is passed through the groove 131. Thus, the placement of the device is stabilized. In order to avoid interference between the wire and the positioning plate 130, the positioning plate 130 and the positioning groove 111 are spaced apart along the first direction D1 to ensure that the positioning plate 130 can stably support the wire of the device and prevent the wire of the device from bending and falling and causing damage to the wire. In this way, the extended wires can be placed in a targeted manner without interfering with other wires.
[0040] like Figure 1 and Figure 2 As shown, the fixture 100 also includes a limit plate 150, which is connected to the base plate 110. The limit plate 150 is movably connected to the base plate 110. The limit plate 150 can rotate relative to the base plate 110. The limit plate 150 can rotate around the rotation axis. In an optional embodiment, the rotation axis is parallel to the thickness direction of the base plate 110, and the limit plate 150 rotates horizontally. In another optional embodiment, the rotation axis is parallel to the first direction D1, and the limit plate 150 rotates vertically.
[0041] The limiting plate 150 can move between a limiting position and an open position relative to the bottom plate 110. The limiting plate 150 located at the open position is used to be spaced apart from the device. In this way, it is convenient to take and place the device. The limiting plate 150 located at the limiting position is used to abut against the device. The limiting plate 150 located at the limiting position abuts against the device along the first direction D1. The limiting plate 150 located at the limiting position can limit the movement of the device along the first direction D1. The limiting plate 150 located at the limiting position is used to limit the movement of the device along the first direction D1, thereby limiting the movement of the device along the first direction D1, and further preventing the device from deflecting along the first direction D1.
[0042] The second direction D2 is parallel to the X-axis direction. Figure 1 As shown, the limiting plate 150 at the limiting position is parallel to the second direction D2. Figure 2 As shown, the limiting plate 150 at the limiting position can move counterclockwise to the open position. The limiting plate 150 at the open position can move clockwise to the limiting position. Of course, the position of the limiting member 116 can be adjusted so that the limiting plate 150 at the limiting position can move clockwise to the open position, and the limiting plate 150 at the open position can move counterclockwise to the limiting position, and this embodiment does not limit this.
[0043] like Figure 1 As shown, the limiting plate 150 located at the limiting position can stably press the device, ensuring that the device will not shift slightly during the marking process, and ensuring the accuracy of the marking position. The limiting plate 150 located at the limiting position can stably press the front end of the device. In particular, the limiting plate 150 located at the limiting position can ensure that the device will not shift slightly during the marking process, and ensure the accuracy of the unmarked position. In this way, the limiting plate 150 located at the limiting position can prevent the device from shifting in position. The spacing between the limiting plate 150 located at the limiting position and the positioning groove 111 matches the size of the device to ensure that the limiting plate 150 located at the limiting position can offset the device.
[0044] Furthermore, the groove 131 of the positioning plate 130 can prevent the device from being displaced. The groove wall of the groove 131 is used to limit the movement of the wire of the device along the second direction D2, thereby limiting the movement of the device along the second direction D2, and preventing the device from being displaced along the second direction D2. The positioning groove 111 is used to place the device, which can prevent the device from being displaced during the placement process. The limiting plate 150 located at the limiting position can press the device to avoid secondary displacement caused by the marking process. In particular, secondary displacement caused by the marking process is avoided. In this way, both the artificial placement displacement and the secondary displacement during the marking process are solved, and the adverse effects caused by the printing displacement are solved.
[0045] According to the jig 100 for laser marking of devices of the utility model, the jig 100 includes a base plate 110, a positioning plate 130 and a limiting plate 150. The base plate 110 is provided with a positioning groove 111, and the positioning groove 111 is used to place the device. The positioning plate 130 is connected to the base plate 110 and protrudes from the base plate 110. The positioning plate 130 is provided with a groove 131, and the groove 131 is used to place the wire of the device. The limiting plate 150 is connected to the base plate 110, and the limiting plate 150 can move between a limiting position and an open position relative to the base plate 110. The limiting plate 150 located at the limiting position is used to abut against the device, and the limiting plate 150 located at the open position is used to be spaced apart from the device. In this way, the device is placed in the positioning groove 111, and the wire of the device is placed in the groove 131. The positioning groove 111 of the base plate 110 and the groove 131 of the positioning plate 130 can both prevent the device from producing angle and position deviation. The limit plate 150 located at the limit position can limit the device, reduce laser marking errors, facilitate operator operation, improve efficiency, reduce product defective rate, and prevent safety accidents.

Within this range, according to this position arrangement, the maximum utilization rate can be achieved. At least two devices can be placed in at least two positioning grooves 111 respectively. In this way, accurate positioning can be achieved. Preferably, at least two devices can be placed in at least two positioning grooves 111 of the same bottom plate 110 respectively. At least two positioning grooves 111 are used to place at least two devices respectively. In this way, the fixture 100 can stack at least two devices as a whole, and can also effectively improve work efficiency. For example, the bottom plate 110 has a total of 5 rows, and each row is arranged with 6 positioning grooves 111. There is a groove 131 for placing the output terminal of the device under each row of positioning grooves 111, and there are wiring grooves. In this way, the placement of the parts is stable and the wiring is clear. Of course, the number of positioning grooves 111 can also be adjusted according to actual conditions, and this embodiment does not intend to limit this. The fixture 100 can also be set to multiple according to actual conditions, and the operator can mark the work during the stacking process to achieve seamless connection.
[0058] like Figure 6 As shown, the positioning plate 130 is provided with at least two grooves 131, and the at least two grooves 131 are used to place the wires of at least two devices respectively. The at least two grooves 131 correspond to the at least two positioning grooves 111 respectively. In this way, the same positioning plate 130 can support the wires of at least two devices at the same time. The at least two grooves 131 of the same positioning plate 130 can position the at least two devices respectively to prevent the positions of the at least two devices from shifting. In this way, the extended wires can be placed in a targeted manner without interfering with the wires of the next row.
