[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation mode of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0037] Referring to the accompanying drawings, the eyeglass temple pin assembly machine in the embodiment of the present embodiment includes a heating device 60, a temple pin insertion device 61, a needle feeding device 62, a needle clamping and transferring device 63 and a plate removing and material taking device 64.

[0038] The temple pin insertion device 61 includes a push pin channel 65, the entrance end of the push pin channel 65 is provided with a push pin rod 66, and the push pin channel 65 is arranged horizontally. When the needle core 15 is inserted and placed in the entrance of the push pin channel 65, the push pin rod 66 cooperates to further push the needle core 15, so that the needle core 15 can be inserted into the temple 14. For example, CN211028849U temple pin insertion device.

[0039] Among them, the needle feeding device 62 includes a material bin 67, a needle feeding platform 68 and a vibrator. The vibrator is connected to the material bin 67 and the needle feeding platform 68. The needle core 15 is placed in the material bin 67. The material bin 67 has a vertical needle gap 69. The needle feeding platform has a needle feeding groove 70. The vertical needle gap 69 is connected with the needle feeding groove 70. Through the vibration of the vibrator, the needle cores 15 enter the vertical needle gap 69 one by one and stand up, and move forward along the needle feeding groove 70 one by one. The end of the needle feeding groove 70 is provided with a limit stop 71. The needle core 15 moves along the needle feeding groove 70 and is blocked by the limit stop 71 (such as a limit block, etc.) to wait for subsequent processing. For example, CN209973563U needle feeding device 62. The needle feeding platform 68 can use an inclined plate, and the needle core 15 will be hung on the needle feeding groove 70. During the vibration process, the needle core 15 slowly slides down to its place.

[0040] Among them, a receiving plate 25 is connected between the heating device 60 and the temple pin insertion device 61, and the receiving plate 25 is arranged to move longitudinally, that is, the receiving plate 25 is arranged to move back and forth longitudinally, and the receiving plate 25 has a concave groove 41, and the concave groove 41 is open upward (for the temple 14 to be put in and taken out), and the horizontal front end or the horizontal rear end of the concave groove 41 is set as an open opening 51 (that is, an open opening) for the shovel plate 39 to shovel in and the needle core 15 to be inserted, and the concave groove 41 is for the temple 14 to be matched and placed, and the concave groove 41 is arranged horizontally on the receiving plate 25 ( That is, it is arranged in a horizontal direction), the receiving plate 25 is used to receive the temple 14 for longitudinal movement, so that the temple 14 can be transferred to different positions. After receiving the temple 14 from the heating device 60, the receiving plate 25 can be longitudinally moved to the temple pin insertion device 61 for pin insertion (inserting the needle core 15 into the temple 14). After the pin insertion is completed, the temple 14 is longitudinally moved out and then detached from the concave groove 41 of the receiving plate 25. After the detachment of the temple 14 is completed, the receiving plate 25 is moved to the heating device 60 again to receive the temple 14.

[0041] The heating device 60 includes a lifting support plate 1 , a clamping mechanism 2 , a heating mechanism 3 and a stripping mechanism 4 .

[0042] The lifting support plate 1 is located below the clamping mechanism 2. The lifting support plate 1 rises to a position and is supported below the clamping mechanism 2. When the temple 14 is placed, the temple 14 is supported, and the clamping mechanism 2 clamps the supported temple 14. After the position of the temple 14 is corrected and stabilized, the temple 14 is heated smoothly. The lifting action of the lifting support plate 1 can be driven by a cylinder 26 or a motor.

[0043] The clamping mechanism 2 includes a front baffle plate 5 and a rear push plate 6. The rear push plate 6 moves toward the front baffle plate 5 to clamp the temple 14. The temple 14 will be clamped by the rear push plate 6 and the front baffle plate 5. When the temple 14 is clamped, its relative position can be corrected so that the relative position of the temple 14 is in a set position for heating and subsequent material removal and transfer. Avoid the problem of inaccurate position leading to failure to heat smoothly. Additional correction guide slopes can be set on the front baffle plate 5 and the rear push plate 6 to cooperate with the position correction in the process of clamping the temple 14 to be more accurate and smoother.

[0044] The heating mechanism 3 includes a lifting die head 8, which is arranged above the clamping mechanism 2. The lifting die head 8 descends to contact the temple 14 for heating. The lifting die head 8 rises and resets to wait for the next work.

[0045] The stripping mechanism 4 includes a stripping pressing block 10, which is arranged above the clamping mechanism 2, and a receiving plate 25 is arranged below the clamping mechanism 2; the clamping mechanism 2 cooperates to correct the position of the temple 14 clamped, and the stripping pressing block 10 can cooperate to press the heated temple 14 downward to stably strip the temple 14, and the relative position of the temple 14 will not shift, so that the receiving plate 25 below the clamping mechanism 2 can move longitudinally into position to receive the temple 14, and the temple 14 will smoothly enter the concave groove 41 and be stably and accurately received by the receiving plate 25 (the relative position will not shift), so that the subsequent insertion of the temple 14 will be smoother and more stable.

[0046] When the heating device 60 is in operation, the temple 14 is located in the clamping mechanism 2, and is supported by the lifting support plate 1 at the bottom. Then, the clamping mechanism 2 clamps the temple 14, and corrects the relative position of the temple 14 while clamping. After the position of the temple 14 is corrected, the lifting die head 8 descends to contact the temple 14 for heating. Then, the lifting support plate 1 descends, the lifting die head 8 rises, and the stripping block 10 begins to descend when it is in place. The stripping block 10 descends to press the clamped temple 14 downward, so that the temple 14 is smoothly and stably detached, so that the heated temple 14 can be stably and accurately received by the receiving plate 25 downward. The heating device 60 has a reasonable structure and layout, and can heat the temple 14 so that the subsequent needle core 15 can be smoothly inserted. The relative position of the temple 14 in the heating device 60 is corrected, and when detached, it can be stably and accurately transferred downward by the pressure of the stripping block 10, and can be stably and accurately received by the receiving plate 25 for transfer, which is convenient for heating and subsequent transfer processing. The temples 14 can be placed on the lifting support plate 1 by a manipulator, a robot or manually, or the temples 14 can be arranged and stacked in the material warehouse 19 (the temples 14 are supported by the bottom plate 20 of the material warehouse 19), the lower end of the material warehouse 19 is the discharge port, and the temples 14 on the bottom layer of the material warehouse 19 are directly pushed out horizontally from the discharge port to the lifting support plate 1 that has risen into place by the push head 21, and then the temples 14 are clamped by the rear push plate 6 and the front baffle 5; in the figure, the push head 21 pushes the temples 14 horizontally, and there is a height difference or flushness between the bottom plate 20 of the material warehouse 19 and the lifting support plate 1 that has risen into place, and the height difference can form a limiting step structure, and the height difference after the temples 14 are pushed out by the push head 21 can cooperate to limit the temples 14.

[0047] Among them, the temple pin insertion device 61 also has a support platform 72, which is arranged at the exit end 84 of the pin pushing channel 65. The support platform 72 is for the receiving plate 25 to stay. When the receiving plate 25 moves longitudinally, it is supported by the support platform 72. A lifting and pressing plate 73 is provided above the support platform 72. The lifting and pressing plate 73 can be driven by power (motor or cylinder 85, etc.) to perform lifting and lowering movements. The lifting and pressing plate 73 descends to cooperate with the receiving plate 25 to press the receiving plate 25 on the support platform 72, and can press and fix the temple 14 in the concave groove 41 of the receiving plate 25, so that the needle core 15 can be smoothly inserted to ensure smooth insertion of the pin.

[0048] Among them, the end of the needle feeding groove 70 of the needle feeding device 62 is also equipped with a clamping needle lifting mechanism 74, which includes a first clamp 75. When the needle core 15 moves forward along the needle feeding groove 70 to the position (blocked by the limit stop 71), it is clamped and lifted by the clamping needle lifting mechanism 74. The clamping needle lifting mechanism 74 clamps and releases the needle core 15 by the first clamp 75. The first clamp 75 can be pneumatic fingers, etc., and the lifting and lowering of the first clamp 75 can be driven by a cylinder 91 or a motor. After the needle core 15 is clamped and lifted one by one by the clamping needle lifting mechanism 74, the subsequent transfer is smoother and more stable. The first clamp 75 can be located at the front side of the needle feeding groove 70.

[0049] Among them, the clamping needle transfer device 63 is connected and arranged between the clamping needle lifting mechanism 74 and the temple needle insertion device 61. After the clamping needle lifting mechanism 74 clamps the needle core 15 and lifts it, the clamping needle transfer device 63 cooperates to clamp the rising needle core 15 for convenient transfer, and cooperates to transfer the needle core 15 and insert it into the entrance of the push-pin channel 65, and then the push-pin rod 66 cooperates to push the needle core 15 into the temple 14, and inserts it into the temple 14 of the concave groove 41 of the receiving plate 25 located on the support plate platform 72. It can be further optimized, wherein the temple pin insertion device 61 includes a channel seat 87, and the push pin channel 65 is arranged on the channel seat 87. In the figure, an electric heating wire or an electric heating plate or high-frequency heating is arranged on the channel seat to heat the needle core 15 in the push pin channel 65. The channel seat 87 can be divided into a main seat 81 and a sub-seat 82. The main seat 81 can be arranged with a rolling column, etc., such as the structure in the temple pin insertion device of CN211028849U, and the sub-seat 82 is used as a preheating structure of the main seat 81. When the needle core 15 is inserted into the push pin channel 65 of the sub-seat 82, it can be heated at a high temperature (up to about 300°C), so that the heating temperature of the main seat 81 can be relatively low, so as to avoid the main seat 81 from being too high in temperature and affecting the operation of the rolling column, etc. in the push pin channel 65. In the figure, an additional sub-seat is arranged, but of course, only the main seat can be arranged.

[0050] The needle clamping and transferring device 63 includes a transverse frame 76, a lifting frame 77 and a rotating arm 78. The lifting frame 77 is arranged on the transverse frame 76. The lifting frame 77 moves up and down on the transverse frame 76. The lifting frame 77 moves back and forth laterally with the transverse frame 76. The rotating arm 78 is arranged on the lifting frame 77. The rotating arm 78 rotates on the lifting frame 77. A motor 86 or a cylinder or other power can be configured to drive the rotating arm 78 to rotate on the lifting frame 77. The rotating arm 78 is provided with a second clamp 79. The second clamp 79 can be a pneumatic finger, etc. The second clamp 79 cooperates to clamp and release the needle core 15. It can also be optimized to set a longitudinal frame 83 on the lifting frame 77 for the rotating arm 78 to be installed and connected, so that the rotating arm 78 can also move longitudinally on the lifting frame 77 to adjust the position relatively. The longitudinal frame 83 can be driven by the cylinder 89 to move longitudinally on the lifting frame 77.

[0051] The plate-removing and material-retrieving device 64 comprises a leg-retrieving mechanism 30 and a leg-shoveling mechanism 31 , and the leg-retrieving mechanism 30 is arranged above the receiving plate 25 .

[0052] The leg-taking mechanism 30 includes a translation seat 32, which moves back and forth in a horizontal direction (usually horizontally or vertically, the translation seat 32 moves horizontally in the figure, and the translation seat 32 can be arranged on a horizontal track 59), and can be driven by a motor or a cylinder or other power to move. A lifting plate 33 is arranged on the translation seat 32, and the lifting plate 33 moves up and down on the translation seat 32, and can be driven by a motor or a cylinder or other power to move up and down. The lifting plate 33 moves horizontally with the translation seat 32. A jack needle 34 and a supporting component 35 are provided on the lifting plate 33. A mounting bracket 57 can be provided on the lifting plate 33 for installation and connection of various components. A pinhole 52 is provided on the supporting component 35. The jack needle 34 is inserted into the hinge hole 16 on the needle core 15 of the temple 14. The jack needle 34 is inserted into the hinge hole 16 on the needle core 15 and then inserted into the pinhole 52. The supporting component 35 cooperates to support the jack needle 34, and the structure is more solid and stable. The jack needle 34 is inserted into the hinge hole 16 to cooperate with taking out the temple 14.

[0053] The lifting plate 33 is also provided with a first driving device 36 and a second driving device 37. The first driving device 36 is in transmission connection with the jack pin 34, and the first driving device 36 cooperates to drive the jack pin 34 to move, so that the jack pin 34 cooperates to insert into the hinge hole 16 of the needle core 15 of the temple 14. The second driving device 37 is in transmission connection with the support component 35, and the second driving device 37 cooperates to drive the support component 35 to move, so that the pinhole 52 on the support component 35 can be inserted by the jack pin 34, and cooperate with each other to firmly and stably support the hinge hole 16 of the needle core 15 on the temple 14, so as to support the temple 14. The first driving device 36 and the second driving device 37 can use a motor or a cylinder as a power source. In the figure, the first driving device 36 uses a cylinder, and the jack pin 34 is set (can be clamped) on the needle seat 58 for connection and transmission.

[0054] The leg taking mechanism 30 is arranged above the receiving plate 25, and the receiving plate 25 is arranged below the leg taking mechanism 30 to move longitudinally. A board-removing material taking station is arranged below the leg taking mechanism 30, and the leg shoveling mechanism 31 is arranged at the board-removing material taking station. The receiving plate 25 moves horizontally to the board-removing material taking station, and the leg taking mechanism 30 and the leg shoveling mechanism 31 cooperate to take the temple 14 out of the concave groove 41.

[0055] The leg-shoveling mechanism 31 includes a transverse displacement seat 38, which will move back and forth transversely, and can be configured with a motor or a cylinder or other power to drive the transverse movement, and a transverse track 29 can be provided for the transverse displacement seat 38 to move. The transverse displacement seat 38 is provided with a shoveling plate 39, which is used to shovel the temple 14 out of the concave groove 41 of the receiving plate 25, to remove the temple 14, and to separate the temple 14 from the receiving plate 25. The leg-shoveling mechanism 31 can be configured below the leg-taking mechanism 30.

[0056] After the temple 14 is inserted into the concave groove 41 of the receiving plate 25 by the needle core 15, the temple 14 needs to be removed from the receiving plate 25, and the plate-removing and material-taking device 64 of the present invention cooperates to remove the temple 14 from the receiving plate 25, so that the temple 14 is separated from the receiving plate 25. Among them, after the jack needle 34 is translated with the translation seat 32 and the lifting and lowering movement of the lifting plate 33 to the position, the jack needle 34 will cooperate to be inserted from the front side into the hinge hole 16 of the needle core 15 on the temple 14 in the concave groove 41 of the receiving plate 25, and the jack needle 34 is inserted into the hinge hole 16 on the needle core 15 and then inserted into the pinhole 52 of the supporting component 35, and cooperates with each other to firmly and stably support the hinge hole 16 of the needle core 15 on the temple 14, so as to support the temple 14, cooperate to make the temple 14 separate from the receiving plate 25, and prevent the temple 14 from shifting during the separation process. After the temple 14 is inserted into the support along with the needle core 15, the shovel plate 39 moves laterally along with the transverse displacement seat 38 to cooperate in shoveling the temple 14 out of the concave groove 41 of the receiving plate 25, thereby making the temple 14 detach from the receiving plate 25. During the shoveling process, the hinge hole 16 of the needle core 15 of the temple 14 is always inserted with a support point, and the relative position is controllable to prevent the temple 14 from detaching and falling. The plate-removing and material-removing device 64 cooperates with the insertion needle 34 in the leg-removing mechanism 30 to insert the needle core 15 of the temple 14 into the hinge hole 16 and then insert it into the pinhole 52 of the supporting component 35 for cooperative support, so as to cooperate with the shoveling plate 39 to shovel out the temple 14 and make the temple 14 detach from the receiving plate 25. During the shoveling process, the needle core 15 of the temple 14 is always inserted with a support point to avoid the temple 14 from being offset, and to avoid the problems of the temple 14 having no support and inconsistent relative position after being shoveled out, so that it is more stable; it can cooperate to remove the temple 14 from the concave groove 41 of the receiving plate 25, and the removed temple 14 can be transferred by the leg-removing mechanism 30.

[0057] Working principle: the needle core 15 is placed in the material bin 67, and the temple 14 is placed on the lifting support plate 1. The needle core 15 will be transported to the end of the needle feeding groove 70 in the needle feeding device 62, and then clamped and lifted by the clamping needle lifting mechanism 74. Then, the upright needle core 15 is clamped by the clamping needle transfer device 63 to rise, rotate to a horizontal position, and put into the entrance of the push needle channel 65; the temple 14 is raised by the lifting support plate 1 to the clamping mechanism 2, and the clamping mechanism 2 cooperates to clamp the temple 14, and the lifting die head 8 of the heating mechanism 3 descends to contact the temple 14 for heating. After the heating is completed, the lifting die head 8 The lifting and resetting is performed, the lifting and supporting plate 1 is lowered, the receiving plate 25 is longitudinally moved to the bottom of the clamping mechanism 2, and the stripping pressing block 10 cooperates to press the heated temple 14 downward, so that the heated temple 14 in the clamping mechanism 2 is separated, and the temple 14 will smoothly enter the concave groove 41 of the receiving plate 25; the receiving plate 25 is longitudinally moved to the supporting plate platform 72 and supported, and the lifting and pressing plate 73 is lowered to press the receiving plate 25 and the temple 14 in the concave groove 41. At this time, the needle core 15 placed in the entrance of the push needle channel 65 is pushed horizontally by the push needle rod 66 and inserted into the temple 14 in the concave groove 41. The concave groove 41 is opened upward and the end of the concave groove 41 is opened in the direction of the shovel plate 39 horizontally, so that the temple 14 is placed from the top, the needle core 15 is inserted from the horizontal direction, and the shovel plate 39 is shoveled in from the horizontal direction. After the needle core 15 is inserted into the temple 14, the needle pusher 66 retracts laterally, the lifting and pressing plate 73 rises, the receiving plate 25 moves longitudinally and moves out from the supporting platform 72, and the receiving plate 25 moves to the board removing device 64, and the board removing device 64 cooperates to remove the temple 14 from the receiving plate 25.

[0058] The eyeglass leg pin assembly machine can realize the supply and delivery of the needle core 15, the heating of the temple 14, and the assembly of the needle core 15 and the temple 14, thereby realizing the mechanized assembly of the temple 14 and the needle core 15. The structure layout is reasonable and can effectively improve the efficiency and assembly stability.

[0059] The following optimization or further explanation may be performed based on the above embodiments.

[0060] Among them, the heating station, the pin insertion station, and the board removal station are arranged in a longitudinal arrangement (the longitudinal arrangement order does not need to be specifically arranged), and the receiving plate 25 moves among the heating station, the pin insertion station, and the board removal station. At the pin insertion station, the opening 51 of the receiving plate 25 faces the pin pushing channel 65, and at the board removal station, the opening 51 of the receiving plate 25 faces the scraping plate 39. The pin pushing channel 65 and the scraping plate 39 are arranged on the same side of the receiving plate 25 that moves longitudinally (that is, the opening 51 faces one side).

[0061] For example, the receiving plate 25 is arranged on the longitudinal track 40, and the receiving plate 25 is connected to the longitudinal driving device so that the receiving plate 25 can move back and forth longitudinally on the longitudinal track 40. The longitudinal driving device can be equipped with a cylinder or a motor to drive the receiving plate 25 to move longitudinally. Even the receiving plate 25 can also perform additional lifting actions on the longitudinal track 40, and can be additionally equipped with a motor or a cylinder 17 to drive the lifting. The lifting of the receiving plate 25 can better connect and cooperate with the heating device 60 and the temple pin device 61, and has a greater degree of freedom, so that it is convenient to lift and lower it on the pallet platform 72 for operation, for example, it can be more stably and smoothly attached to the lower side of the clamping mechanism 2 and the upper side of the pallet platform 72. The rear push plate 6 is connected to the clamping driving device 7, and the rear push plate 6 is connected to the clamping driving device 7 (such as a motor or a cylinder, etc.), and the clamping driving device 7 cooperates to drive the rear push plate 6 to move toward the front baffle 5 so as to clamp the temple 14. The lifting die head 8 is connected to the lifting drive device 9 (such as a motor or / and a cylinder, etc.) by transmission, and the lifting drive device 9 cooperates to drive the lifting die head 8 to lift. The push pin rod 66 is connected to the push pin drive device 80 by transmission, and the push pin drive device 80 cooperates to drive the push pin rod 66 to move back and forth horizontally. In the figure, the push pin drive device 80 drives the slide plate 90 to move horizontally, and the push pin rod 66 is installed on the rod seat 90, and the rod seat is set on the slide plate 90. The lifting drive device 9 and the push pin drive device 80 can use a cylinder or a motor as a power source.

[0062] For example, the heating mechanism 3 also includes a high-frequency induction heater, and the lifting die head 8 is connected to the high-frequency induction heater to heat the temple 14 by high-frequency heating. The high-frequency induction heater has mature technology, good heating effect, fast speed and stability. Of course, the lifting die head 8 can also be connected to a heating wire or a heating tube for heating.

[0063] When heating, the lifting die head 8 is located above the clamping mechanism 2 and cooperates with the lifting action, descends to heat the temple 14, and rises and retreats. When stripping, the stripping pressing block 10 is located above the clamping mechanism 2 and cooperates with the lifting action, descends to press the clamped temple 14, discharges the temple 14 downward, and rises and retreats to vacate the position. The die head 8 and / or the stripping pressing block 10 can move horizontally, vertically, or rotated, so that they can be switched to the top of the stripping mechanism 4 during operation to perform cooperative actions.

[0064] For example, the lifting die head 8 is arranged to move longitudinally, the stripping pressing block 10 is arranged to move longitudinally, the lifting die head 8 is arranged to be lifted and lowered, and the stripping pressing block 10 is arranged to be lifted and lowered.

[0065] For example, a lifting seat 12 is arranged above the clamping mechanism 2, and the lifting seat 12 is connected to the lifting drive device 9 by transmission, and the lifting drive device 9 cooperates to drive the lifting seat 12 to perform lifting and lowering actions, and the lifting drive device 9 may include a cylinder or a motor, etc. A longitudinal movement plate 23 is connected to the lifting seat 12, and the longitudinal movement plate 23 can move longitudinally on the lifting seat 12 (it can be configured with a motor or a cylinder 27 or other power to drive the longitudinal movement), the lifting die head 8 is connected to the longitudinal movement plate 23, and the stripping pressing block 10 is connected to the longitudinal movement plate 23. The lifting die head 8 and the stripping pressing block 10 can switch positions with the longitudinal movement of the longitudinal movement plate 23, can switch to align with the clamping mechanism 2 below to perform corresponding heating or stripping, and can be lifted and lowered together with the longitudinal movement plate 23 on the lifting seat 12. In addition, a stripping lifting drive cylinder 22 is provided between the stripping pressing block 10 and the longitudinal moving plate 23. The stripping pressing block 10 is transmission-connected to the stripping lifting drive cylinder 22. The structure is reasonable, the lifting stroke of the stripping pressing block 10 is larger, more positions can be avoided, and it can be lifted and lowered on the longitudinal moving plate 23 additionally.

[0066] The concave groove 41 is provided with a notch 42 at the bottom of the opening 51, and the notch 42 allows the convex tooth 43 to enter and move upward, so as to lift the temple 14. The lateral displacement seat 38 is provided with a lifting power device 44, which is in transmission connection with the shovel plate 39, and the shovel plate 39 is driven by the lifting power device 44 to lift and lower the shovel plate 39 on the lateral displacement seat 38. The lifting power device 44 can be powered by a motor or a cylinder, and the shovel plate 39 is provided with a convex tooth 43, which is correspondingly matched with the notch 42. When the convex tooth 43 moves laterally with the shovel plate 39 and is inserted into the notch 42, the convex tooth 43 will be below the end of the concave groove 41. When the notch 42 is lifted, the convex tooth 43 will be below the end of the concave groove 41. When the temple 14 is in the groove 41, the convex teeth 43 will also be located below the temple 14. When the convex teeth 43 rise with the shovel plate 39, the temple 14 can be lifted upwards in coordination, and the end of the temple 14 is first lifted out of the concave groove 41. At this time, the jack needle 34 on the lifting plate 33 has been inserted into the hinge hole 16 and the needle hole 52 of the needle core 15 on the temple 14 in advance. When the shovel plate 39 rises, the lifting plate 33 will also rise in coordination, and the temple 14 can be lifted in coordination with each other. After the temple 14 is lifted, the shovel plate 39 can move horizontally to smoothly shovel the temple 14 out of the concave groove 41 of the receiving plate 25.

[0067] The jack pin 34 cooperates to penetrate the hinge hole 16 and then inserts into the pinhole 52, and separates to cooperate to release the action. For example, the jack pin 34 is arranged to move forward and backward on the lifting plate 33, that is, the first driving device 36 cooperates to drive the jack pin 34 to move forward and backward longitudinally. For example, the support component 35 is set to move forward and backward and to move up and down on the lifting plate 33 (the second driving device 37 can be set to drive the lifting and forward and backward movement with a cylinder or motor, and multiple cylinders or motors can be set). By lifting, it can avoid the position so that the receiving plate 25 can move longitudinally through (the side of the hinge hole 16 on the needle core 15 of the temple 14 can be inserted by the jack needle 34), and the forward and backward movement can allow the jack needle 34 to cooperate in inserting and pulling out (exiting) the hinge hole 16; or, the support component 35 is swingably set on the lifting plate 33 (the support component 35 is connected to the hinge shaft 45 to form a swing arm structure), the second driving device 37 is connected to the support component 35 in a transmission manner, the second driving device 37 drives the support component 35 to swing, and the pinhole 52 located on the support component 35 swings with the support component 35. By swinging and shifting, the second driving device 37 only needs one power drive, that is, it can avoid the position and cooperate with the insertion of the jack needle 34 into the pinhole 52. In the figure, the support component 35 is set on the horizontal hinge shaft 45 for swinging.

[0068] In addition, the lifting plate 33 is also provided with an auxiliary support plate 46, which is in transmission connection with the support drive device 54, and is driven by the support drive device 54 to move and support the temple 14 shoveled out by the shovel plate 39. When the hinge hole 16 of the needle core 15 of the temple 14 is inserted, the auxiliary support plate 46 can be driven by the support drive device to move to the bottom of the temple 14 to support the temple 14. After the temple 14 is shoveled out, the auxiliary support plate 46 can be supported. After the shovel plate 39 is removed, the relative position of the temple 14 is prevented from changing. The support drive device 54 can use a motor and / or a cylinder. There are many ways for the auxiliary support plate 46 to move. For example, the auxiliary support plate 46 is lifted and lowered on the lifting plate 33 and is arranged to move horizontally or vertically. In the figure, the auxiliary support plate is driven to lift and lower by the cylinder 55 and to move vertically by the cylinder 56. After the auxiliary support is supported, it is convenient for subsequent cutting and transfer with the translation seat 32.

[0069] It can also be optimized by setting a cutting mechanism 47 on the transverse moving seat 38. The cutting mechanism 47 moves laterally together with the transverse moving seat 38. The cutting mechanism 47 includes a cutting knife 48. Generally, the cutting knife 48 is driven by a motor 49 to rotate and cooperate with the rotary cutting. The cutting mechanism 47 cooperates with the cutting under the temple 14 to remove burrs, make the surface smoother, and make the thickness of the temple 14 relatively consistent. In addition, a height measuring mechanism 50 (such as a height meter, etc.) can be further provided on the transverse displacement seat 38, and the height measuring mechanism 50 cooperates to measure the relative height of the temple 14 detached from the concave groove 41 of the receiving plate 25. The lifting plate 33 can adjust the relative height by lifting and lowering, so that the cutting mechanism 47 can cut as needed to make the thickness of the temple 14 relatively consistent; of course, the height measuring mechanism 50 can be set up and lowered on the transverse displacement seat 38, such as being equipped with a cylinder 53 or a motor to drive the lifting and lowering, so as to rise to cooperate in measuring the height and fall back to the avoidance position; wherein the height measuring mechanism 50 is located between the shovel plate 39 and the cutting mechanism 47, and when the transverse displacement seat 38 moves laterally toward the receiving plate 25, the shovel plate 39, the height measuring mechanism 50, and the cutting mechanism 47 can operate and work in sequence.
