A positioning mechanism needs to be set on the jig to position the workpiece to improve the processing accuracy of the workpiece. However, the positioning mechanism will block the surface to be processed of the workpiece, and the equipment cannot process the surface to be processed in one go. Manual adjustments to the workpiece are required to complete the processing. The processing efficiency is low, and manual labor is required, which is costly. Utility Model Content

The positioning device includes at least two positioning pins, which are mounted on the first base and are arranged on both sides of the support surface. The positioning pins can move between a positioning position and an avoidance position. When the positioning pins are in the positioning position, the support surface is located between the two positioning pins. When the positioning pins are in the avoidance position, the top of the positioning pins is lower than the support surface, or the top of the positioning pins is flush with the support surface.

[0005] The clamping device includes a clamping block, which is mounted on the first base and can move between a clamping position and a loosening position. When the clamping block is in the clamping position, the clamping block abuts against the side of the workpiece away from the supporting surface. When the clamping block is in the loosening position, the clamping block is away from the workpiece.

[0006] The jig provided in the embodiment of the present application can be used on equipment for surface treatment, such as laser engraving equipment. The workpiece is fixed by the cooperation of the positioning pin and the pressure block. When the positioning pin is in the positioning position and the pressure block is in the loose position, the workpiece is placed on the support surface, and then the pressure block moves to the clamping position first, and then the positioning pin moves to the avoidance position. On the one hand, the workpiece is placed between the two positioning pins for positioning, and the positioning accuracy of the workpiece is higher, and thus the accuracy of workpiece processing is higher.

[0007] On the other hand, after the pressure block presses the workpiece, the positioning pin moves to the avoidance position, and the top of the positioning pin is lower than the support surface, or the top of the positioning pin is flush with the support surface. The positioning pin will not block the workpiece surface to be processed, and the surface to be processed can be processed in one go, without the need for manual secondary adjustment of the workpiece, thereby improving production efficiency and reducing costs.

[0008] At the same time, because the workpiece can be processed without manual secondary adjustment, the factory can use a robot to clamp the workpiece to the fixture. The robot runs at a fast speed, which can not only improve production efficiency but also reduce labor costs.

The rotating section rotates to drive the pressing section to move between the pressing position and the releasing position.

[0010] The pressing block moves between a clamping position and a loosening position by rotating, and the space occupied by the pressing block during movement is small, thereby reducing the space occupied by the fixture in the equipment.

At this time, the positioning pin will not block the surface to be processed of the workpiece, and the laser engraving head can laser engrave the entire surface to be processed at one time. During the laser engraving process, there is no need for manual secondary adjustment of the position of the workpiece, thereby improving production efficiency and reducing production costs.

[0021] At the same time, because the workpiece can be processed without manual secondary adjustment, the factory can use a robot to clamp the workpiece to the fixture. The robot runs at a fast speed, which can not only improve production efficiency but also reduce labor costs.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 The fixture 500 provided in the embodiment of the present application includes a first base 100, a positioning device 200 and a clamping device 300. The first base 100 is provided with a supporting surface 101 for placing a workpiece 400. The positioning device 200 includes at least two positioning pins 201, and the positioning pins 201 are installed on the first base 100. The two positioning pins 201 are arranged on both sides of the supporting surface 101. The positioning pins 201 can move between a positioning position and an avoidance position. When the positioning pins 201 are in the positioning position, the supporting surface 101 is located between the two positioning pins 201. When the positioning pins 201 are in the avoidance position, the top of the positioning pins 201 is lower than the supporting surface 101, or the top of the positioning pins 201 is flush with the supporting surface 101.

[0044] The clamping device 300 includes a clamping block 301, which is mounted on the first base 100 and can move between a clamping position and a release position. When the clamping block 301 is in the clamping position, the clamping block 301 abuts against the side of the workpiece 400 that is away from the support surface 101. When the clamping block 301 is in the release position, the clamping block 301 is away from the workpiece 400. When the positioning pin 201 is in the positioning position and the clamping block 301 is in the release position, the workpiece 400 is placed on the support surface 101, and then the clamping block 301 moves to the clamping position first, and then the positioning pin 201 moves to the avoidance position.

[0045] For details, please refer to Figure 1 The first base 100 includes a support seat 102, two connecting plates 103 and a first fixed plate 104. The support seat 102 is roughly in the shape of a rectangular frame, and the connecting plates 103 and the first fixed plate 104 are roughly in the shape of rectangular plates. The support seat 102 is provided with a through hole 105, and along the Z-axis direction, the through hole 105 passes through the opposite sides of the support seat 102. Along the Z-axis direction, the support seat 102 and the first fixed plate 104 are arranged at intervals, and the two connecting plates 103 are located in the interval between the support seat 102 and the first fixed plate 104. Along the Z-axis direction, one end of the connecting plate 103 is fixed to the support seat 102, and the other end of the connecting plate 103 is fixed to the first fixed plate 104. Along the Z-axis direction, the support surface 101 is arranged on the side of the support seat 102 away from the first fixed plate 104.

[0046] Please refer to Figure 1 and Figure 2 The fixture 500 provided in the embodiment of the present application can be used to fix the peptide strips of the mobile phone frame, such as Figure 2As shown, the workpiece 400 is a peptide strip, and the shape of the peptide strip is U-shaped. Correspondingly, the shape of the support surface 101 is also U-shaped. The support surface 101 includes a first section 106, a second section 107, and a third section 108. Along the X-axis direction, the first section 106 and the second section 107 are spaced and opposite to each other, and the third section 108 is arranged between the first section 106 and the second section 107, and one end of the third section 108 is connected to the first section 106, and the other end of the third section 108 is connected to the second section 107.

[0047] The axis of the positioning pin 201 is perpendicular to the support surface 101. The number of the positioning pins 201 is 6. The 6 positioning pins 201 constitute three positioning groups, namely the first positioning group 202, the second positioning group 203 and the third positioning group 204. The first positioning group 202, the second positioning group 203 and the third positioning group 204 respectively include two positioning pins 201. The two positioning pins 201 of the first positioning group 202 are arranged at intervals along the X-axis direction. The two positioning pins 201 of the first positioning group 202 are respectively arranged on both sides of the second section 107, one of the positioning pins 201 is located in the through hole 105, and the other positioning pin 201 is located outside the through hole 105. Projected along the negative direction of the Z axis, the second section 107 falls into the interval between the two positioning pins 201 of the first positioning group 202, that is, the width of the second section 107 is smaller than the interval between the two positioning pins 201 of the first positioning group 202.

[0048] The two positioning pins 201 of the second positioning group 203 and the third positioning group 204 are arranged at intervals along the Y-axis direction. The two positioning pins 201 of the second positioning group 203 are respectively arranged on both sides of the third section 108, one of the positioning pins 201 is located in the through hole 105, and the other positioning pin 201 is located outside the through hole 105.

[0049] The two positioning pins 201 of the third positioning group 204 are also respectively arranged on both sides of the third section 108, one of the positioning pins 201 is located in the through hole 105, and the other positioning pin 201 is located outside the through hole 105. Projected along the negative direction of the Z axis, the third section 108 falls into the interval between the two positioning pins 201 of the second positioning group 203 and the interval between the two positioning pins 201 of the third positioning group 204, that is, the width of the third section 108 is smaller than the interval between the two positioning pins 201 of the second positioning group 203 and the interval between the two positioning pins 201 of the third positioning group 204.

[0050] The positioning device 200 further includes a second fixing plate 205, which is mounted on the first base 100 and is located between the support seat 102 and the first fixing plate 104. The six positioning pins 201 are indirectly mounted on the first base 100 by being fixed to the second fixing plate 205. Specifically, the six positioning pins 201 are fixed to one side of the second fixing plate 205 along the thickness direction, that is, the positioning pins 201 are fixed to the side of the second fixing plate 205 facing the positive direction of the Z axis. The second fixing plate 205 can move along the Z axis to push the six positioning pins 201 to move along the Z axis.

[0051] When the positioning pin 201 moves to the positioning position, the height of the top end of the positioning pin 201 is higher than the height of the supporting surface 101, that is, the second section 107 is located between the two positioning pins 201 of the first positioning group 202, the third section 108 is located between the two positioning pins 201 of the second positioning group 203, and between the two positioning pins 201 of the third positioning group 204.

[0052] At this time, please refer to Figure 2 The workpiece 400 can be placed on the support surface 101, that is, the workpiece 400 is placed in the interval between the two positioning pins 201 of the first positioning group 202, in the interval between the two positioning pins 201 of the second positioning group 203, and in the interval between the two positioning pins 201 of the third positioning group 204.

[0053] The two positioning pins 201 of the first positioning group 202 are arranged at intervals along the X-axis. When the workpiece 400 is placed in the interval between the two positioning pins 201 of the first positioning group 202, the first positioning group 202 can limit the movement of the workpiece 400 along the X-axis. The two positioning pins 201 of the second positioning group 203 and the third positioning group 204 are arranged at intervals along the Y-axis. When the workpiece 400 is placed in the interval between the two positioning pins 201 of the second positioning group 203 and the interval between the two positioning pins 201 of the third positioning group 204, the second positioning group 203 and the third positioning group 204 can limit the movement of the workpiece 400 along the Y-axis.

[0054] Please refer to Figure 3 , the number of the pressing blocks 301 is four, and the four pressing blocks 301 are used to clamp the workpiece 400 to prevent the workpiece 400 from moving in the positive direction of the Z axis. Specifically, the pressing block 301 is installed on the first base 100, and the pressing block 301 can move between a clamping position and a loosening position. When the pressing block 301 is in the clamping position, the pressing block 301 abuts against the side of the workpiece 400 away from the supporting surface 101. At this time, the pressing block 301 and the supporting surface 101 limit the movement of the workpiece 400 along the Z axis. Finally, the fixation of the workpiece 400 is achieved.

[0055] When the pressing block 301 is in the released position, the pressing block 301 is away from the workpiece 400, and the pressing block 301 no longer abuts against the side of the workpiece 400 away from the supporting surface 101. The workpiece 400 is released, so that the workpiece 400 can be taken out of the fixture 500, or when the pressing block 301 is in the released position, the workpiece 400 can be placed on the supporting surface 101.

[0056] Before the workpiece 400 is placed on the support surface 101, the positioning pin 201 is adjusted to the positioning position, and the pressing block 301 is adjusted to the release position, such as Figure 1 The state shown is that the positioning pin 201 is in the positioning position, and the pressure block 301 is in the released position. Then place the workpiece 400 on the support surface 101, that is, place the workpiece 400 in the interval between the two positioning pins 201 of the first positioning group 202, the interval between the two positioning pins 201 of the second positioning group 203, and the interval between the two positioning pins 201 of the third positioning group 204, so as to realize the positioning of the workpiece 400. Then the pressure block 301 moves to the clamping position again, so that the pressure block 301 abuts against the side of the workpiece 400 away from the support surface 101. At this time, the support surface 101 and the pressure block 301 cooperate to limit the movement of the workpiece 400 along the Z-axis direction to fix the workpiece 400. Figure 3 The state shown is that the pressing block 301 is in the pressing position.

[0057] Please refer to Figure 4 After the workpiece 400 is fixed, the positioning pin 201 moves to the avoidance position. The end surface of the workpiece 400 facing the positioning pin 201 is the surface to be processed 401. When the positioning pin 201 is in the avoidance position, the top of the positioning pin 201 is lower than the support surface 101, or the top of the positioning pin 201 is flush with the support surface 101, and the positioning pin 201 will not block the surface to be processed 401 of the workpiece 400.

[0058] The jig 500 provided in the embodiment of the present application can be used on equipment for surface treatment, such as laser engraving equipment. The workpiece 400 is fixed by the cooperation of the positioning pin 201 and the pressing block 301. On the one hand, the workpiece 400 is placed in the interval between the two positioning pins 201 of the first positioning group 202, the interval between the two positioning pins 201 of the second positioning group 203, and the interval between the two positioning pins 201 of the third positioning group 204. The first positioning group 202, the second positioning group 203, and the third positioning group 204 limit the workpiece 400 in the X-axis and Y-axis directions, and the support surface 101 and the pressing block 301 limit the workpiece 400 in the Z-axis direction. The positioning accuracy of the workpiece 400 is higher, and thus the processing accuracy of the workpiece 400 is higher.

[0059] On the other hand, after the pressing block 301 presses the workpiece 400, the positioning pin 201 moves to the avoidance position, and the top of the positioning pin 201 is lower than the supporting surface 101, or the top of the positioning pin 201 is flush with the supporting surface 101. The positioning pin 201 will not block the surface 401 to be processed of the workpiece 400, and the surface treatment of the surface 401 to be processed can be completed at one time, without manual secondary adjustment of the workpiece 400, thereby improving production efficiency and reducing costs.

[0060] At the same time, because the workpiece 400 can be processed without manual secondary adjustment, the factory can use a robot to clamp the workpiece 400 to the fixture 500. The robot operates at a fast speed, which can not only improve production efficiency but also reduce labor costs.

[0061] In some embodiments, please refer to Figure 3 The pressing block 301 includes a pressing section 302 and a rotating section 303. The pressing section 302 is used to abut against the side of the workpiece 400 away from the supporting surface 101. One end of the rotating section 303 is fixedly connected to one end of the pressing section 302 at an angle, and the other end of the rotating section 303 is hinged to the first base 100. The rotating section 303 rotates to drive the pressing section 302 to move between the pressing position and the releasing position. Specifically, one end of the rotating section 303 is fixedly connected to one end of the pressing section 302 at 90 degrees, and the other end of the rotating section 303 is hinged to the supporting seat 102.

[0062] The pressing block 301 moves between the clamping position and the releasing position by rotating, and the rotating section 303 and the clamping section 302 are connected at an angle. The rotation range of the rotating section 303 and the clamping section 302 is small, and the space occupied by the pressing block 301 when moving is small, thereby reducing the space occupied by the fixture 500 in the equipment.

[0063] In some embodiments, when the pressing block 301 is in the released position, the clamping section 302 is not projected onto the supporting surface 101 along the negative direction of the Z axis, so that when the workpiece 400 is taken out or placed, the workpiece 400 will not interfere with the clamping section 302 during its movement along the Z axis.

[0064] In some embodiments, the clamping device 300 also includes a first driving mechanism, the first driving mechanism includes a first driving end, the first driving end is connected to the rotating section 303, and the first driving end drives the rotating section 303 to rotate. Specifically, the first driving mechanism can be a rotary motor or a cylinder. The driving end of the rotary motor is directly connected to the rotating section 303 to drive the rotating section 303 to rotate. The driving end of the cylinder is indirectly connected to the rotating end to drive the rotating section 303 to rotate. By setting the first driving mechanism to drive the movement of the pressing block 301, the user can adjust the movement of the pressing block 301 through the first driving mechanism, which makes the operation more convenient, thereby improving the production efficiency.

[0065] In some embodiments, please refer to Figure 3 The first driving mechanism includes a first cylinder 304, and the first driving end includes a first telescopic rod 305. The pressing block 301 also includes a connecting section 307, one end of which is fixedly connected to an end of the rotating section 303 away from the pressing section 302, and the other end of the connecting section 307 is hinged to the first telescopic rod 305.

[0066] Specifically, the number of the first cylinders 304 is four, and the four first cylinders 304 drive four pressing blocks 301 respectively. The first cylinder 304 also includes a first body 306, which is disposed between the support seat 102 and the first fixed plate 104, and the first body 306 is fixed to the first fixed plate 104. The first body 306 is connected to the first telescopic rod 305, and the first body 306 drives the first telescopic rod 305 to extend and retract along the Z-axis direction. One end of the connecting section 307 is fixedly connected to the end of the rotating section 303 away from the pressing section 302 at 90 degrees, that is, the shape of the pressing block 301 is Z-shaped. The other end of the connecting section 307 is hinged to the first telescopic rod 305, and the first telescopic rod 305 is extended and retracted along the Z-axis direction to drive the connecting section 307 to move, and the connecting section 307 drives the rotating section 303 to rotate, and the rotating section 303 then drives the pressing section 302 to move.

[0067] By setting the first cylinder 304 to drive the pressing block 301 to move, the cylinder moves faster, the clamping section 302 can quickly clamp the workpiece 400, and the cylinder moves more smoothly, the pressing block 301 has higher movement stability, thereby improving production efficiency and the stability of the fixture 500.

[0068] In some embodiments, the positioning device 200 further includes a second driving mechanism, the second driving mechanism includes a second driving end, the second driving end is connected to the positioning pin 201, and the second driving end drives the positioning pin 201 to move. The second driving mechanism can be a linear motor or a cylinder. By setting the second driving mechanism, the user can adjust the movement of the positioning pin 201 through the second driving mechanism, which makes the operation more convenient, thereby improving production efficiency.

[0069] In some embodiments, please refer to Figure 3The second driving mechanism includes a second cylinder 206, and the second driving end includes a second telescopic rod 207, one end of which is connected to one end of the positioning pin 201. Specifically, the second cylinder 206 is disposed between the first fixed plate 104 and the second fixed plate 205, and the second cylinder 206 also includes a second body 208, the second body 208 is fixed to the first fixed plate 104, one end of the second telescopic rod 207 is connected to the second body 208, and the other end of the second telescopic rod 207 is fixedly connected to the side of the second fixed plate 205 away from the positioning pin 201, that is, the second telescopic rod 207 is indirectly connected to the positioning pin 201. The second body 208 drives the second telescopic rod 207 to extend and retract along the Z-axis direction.

[0070] The second telescopic rod 207 is telescoped along the Z-axis direction to push the second fixed plate 205 to move along the Z-axis direction, and the second fixed plate 205 pushes the positioning pin 201 to move along the Z-axis direction to achieve the movement of the positioning pin 201 between the positioning position and the avoidance position.

[0071] By setting the second cylinder 206 to drive the positioning pin 201 to move, the cylinder has a faster movement speed, and the positioning pin 201 can move quickly between the positioning position and the avoidance position. In addition, the cylinder moves more smoothly, and the positioning pin 201 has higher movement stability, thereby improving production efficiency and the stability of the fixture operation.

[0072] In some embodiments, please refer to Figure 3 , an inclined guide surface 209 is provided at the top of the positioning pin 201. Specifically, along the positive direction of the Z axis, the outer diameter of the top of the positioning pin 201 gradually decreases, that is, the distance between the tops of the two positioning pins 201 gradually increases along the Z axis direction, so that the distance between the tops of the two positioning pins 201 is larger, and when the workpiece 400 is installed between the two positioning pins 201, the workpiece 400 is more easily placed in the distance between the two positioning pins 201, thereby improving the assembly efficiency.

[0073] Please refer to Figure 5 and Figure 6 The second aspect of the present application provides a laser engraving device 1000, including a machine platform 600, a laser engraving machine 700 and a fixture 500 provided in the first aspect of the present application, wherein the laser engraving machine 700 includes a laser engraving head 701, and the laser engraving machine 700 and the fixture 500 are installed on the machine platform 600. The fixture 500 is used to position and press the workpiece 400, and the laser engraving head 701 is used to perform laser engraving on the workpiece 400.

[0074] For details, please refer to Figure 5 and Figure 6When the fixture 500 is installed on the machine 600, the height direction of the fixture 500 is parallel to the length direction of the machine 600, that is, the Z-axis direction is parallel to the length direction of the machine 600. The length direction of the fixture 500 is parallel to the width direction of the machine 600, that is, the X-axis direction is parallel to the width direction of the machine 600. The width direction of the fixture 500 is parallel to the height direction of the machine 600, that is, the Y-axis direction is parallel to the height direction of the machine 600.

[0075] Along the Y-axis direction, the fixture 500 and the laser engraving machine 700 are spaced apart from each other, the laser engraving head 701 and the surface 401 to be processed of the workpiece 400 are spaced apart from each other, and the laser engraving head 701 can perform laser engraving on the surface 401 to be processed. The following is the working process of the laser engraving device 1000:

[0076] Turn off the laser engraving machine 700, adjust the positioning pin 201 to the positioning position, and adjust the pressure block 301 to the loose position, then put the workpiece 400 into the support surface 101, then the first cylinder 304 works, the first telescopic rod 305 drives the pressure block 301 to move to the clamping position, and the clamping section 302 abuts against the side of the workpiece 400 away from the support surface 101 to fix the workpiece 400 on the fixture 500. Then the second cylinder 206 works, driving the positioning pin 201 to move to the avoidance position, and finally the laser engraving machine 700 works, and the laser engraving head 701 performs laser engraving on the surface 401 to be processed of the workpiece 400.

[0077] In the laser engraving device 1000 provided in the embodiment of the present application, on the one hand, the positioning pin 201 positions the workpiece 400 to improve the positioning accuracy of the workpiece 400, so that the processing accuracy of the workpiece 400 is higher. On the other hand, the positioning pin 201 and the pressure block 301 cooperate to fix the workpiece 400. After the workpiece 400 is placed on the support surface 101, the pressure block 301 abuts against the side of the workpiece 400 away from the support surface 101, and the positioning pin 201 moves to the avoidance position. At this time, the positioning pin 201 will not block the surface to be processed 401, and the laser engraving head 701 can laser engrave the entire surface to be processed 401 at one time. During the laser engraving process, the workpiece 400 does not need to be manually adjusted for a second time, thereby improving production efficiency and reducing production costs.

[0078] At the same time, because the workpiece 400 can be processed without manual secondary adjustment, the factory can use a robot to clamp the workpiece 400 to the fixture 500. The robot operates at a fast speed, which can not only improve production efficiency but also reduce labor costs.

[0079] If the positioning pins 201 are not moved to a avoiding position, one of the positioning pins 201 will be located between the surface to be processed 401 and the laser engraving head 701, and the positioning pin 201 will block the surface to be processed 401, so that the laser engraving head 701 cannot engrave the entire surface to be processed 401. In this case, it is necessary to manually adjust the position of the workpiece 400 a second time so that the laser engraving head 701 can engrave the blocked part of the workpiece 401.
