[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, the workpiece is to grasp a fuse. The embodiment of the present utility model provides a blanking translation mechanism, which includes a frame 1, and further includes a rotary drive motor 2 installed on the frame 1. One end of the rotary drive motor 2 is provided with a first synchronous pulley 31, and a second synchronous pulley 32 is installed on one side of the first synchronous pulley 31. A synchronous belt 33 is connected between the first synchronous pulley 31 and the second synchronous pulley 32. The middle of the first synchronous pulley 31 has a first rotating shaft 35. One end of the first rotating shaft 35 is in transmission connection with the rotary drive motor 2, and the other end is provided with a first connecting rod 41. The middle of the second synchronous pulley 32 has a second rotating shaft 36. One end of the second rotating shaft 36 is provided with a positioning member 51, and the other end is provided with a second connecting rod 42. A stop sensor 52 that cooperates with the positioning member 51 is installed on one side of the positioning member 51. A connecting rod arm 43 is installed between the first connecting rod 41 and the second connecting rod 42. One end of the connecting rod arm 43 is provided with a suction cup 44 or a clamping cylinder. A material taking station 61 is provided on one side of the frame 1, and a blanking station 62 is provided on the other side. The suction cup 44 or the clamping cylinder of the connecting rod arm 43 respectively cooperate with the material taking station 61 and the blanking station 62.

[0032] The frame 1 includes a support plate 11 and an installation cross plate 12 horizontally arranged on the support plate 11. The rotary drive motor 2, the positioning member 51 and the stop sensor 52 are respectively installed on the top of the installation cross plate 12. The first synchronous pulley 31, the second synchronous pulley 32, the synchronous belt 33, the first connecting rod 41, the second connecting rod 42 and the connecting rod arm 43 are respectively installed on the bottom of the installation cross plate 12. The first rotating shaft 35 and the second rotating shaft 36 are respectively inserted into the installation cross plate 12.

[0033] A first rolling bearing 14 is embedded on the installation cross plate 12, and the first rotating shaft 35 is inserted on the first rolling bearing 14. A second rolling bearing 15 is embedded on the installation cross plate 12, and the second rotating shaft 36 is inserted on the second rolling bearing 15.

[0034] Reinforcement plates 13 are respectively installed at both ends between the support plate 11 and the installation cross plate 12. (When the blanking translation mechanism translates and blanks, the vibration is relatively large, and the reinforcement plates 13 are required to reinforce the installation cross plate 12.)

[0035] The rotary drive motor 2 is a stepping motor or a servo motor.

[0036] A coupling 21 is installed between the rotary drive motor 2 and one end of the first rotating shaft 35.

[0037] Between one end of the first connecting rod 41 and one end of the connecting rod arm 43, and between the second connecting rod 42 and the other end of the connecting rod arm 43, they are respectively hinged together through a bolt-type roller needle bearing 435. Specifically, one end of the bolt-type roller needle bearing 435 is the threaded part of the bolt, and the other end is a smooth shaft. One end of the smooth shaft is the head of the bolt, and then a rolling bearing is sleeved on the smooth shaft part. First, the smooth shaft of the bolt-type roller needle bearing 435 is sleeved with a rolling bearing. Then, one end of the connecting rod arm 43 is sleeved on the rolling bearing. Next, the threaded part of the bolt-type roller needle bearing 435 is threadedly connected to the first connecting rod 41 or the second connecting rod 42. Finally, the rolling bearing is installed between the first connecting rod 41 or the second connecting rod 42 and the head of the bolt.

[0038] A positioning member 51 is installed at one end of the second rotating shaft 36, and a stop sensor 52 that cooperates with the positioning member 51 is installed on one side of the positioning member 51. The positioning member 51 has two specific embodiments as follows:

[0039] 1. The stop sensor 52 is a concave photoelectric sensor, and the positioning member 51 is a positioning convex block 510A that can pass through the groove 520 of the concave photoelectric sensor. The positioning convex block 510A is sleeved on one end of the second rotating shaft 36. When the positioning convex block 510A rotates to the middle of the groove 520 of the concave photoelectric sensor, the photoelectricity of the concave photoelectric sensor cannot sense, and then the concave photoelectric sensor will control the rotation driving motor 2 to stop with this feedback signal.

[0040] 2. The stop sensor 52 is a concave photoelectric sensor, and the positioning member 51 is a positioning disk 510B that passes through the groove 520 of the concave photoelectric sensor. A detection opening 511B that cooperates with the concave photoelectric sensor is opened on the positioning disk 510B. The positioning disk 510B is sleeved on one end of the second rotating shaft 36. When the detection opening 511B on the positioning disk 510B rotates to the middle of the groove 520 of the concave photoelectric sensor, the photoelectricity of the concave photoelectric sensor senses the signal, and then the concave photoelectric sensor will control the rotation driving motor 2 to stop with this feedback signal.

[0041] A blanking translation mechanism according to an embodiment of the present invention, its specific working principle is as follows:

[0042] The connecting rod arm 43 picks up the fuse at the material taking station 61 through the suction cup 44 or the clamping cylinder.

[0043] The rotation driving motor 2 rotates the first synchronous pulley 31, and the first synchronous pulley 31 drives the second synchronous pulley 32 to rotate through the synchronous belt 33.

[0044] The first rotating shaft 35 of the first synchronous pulley 31 and the second rotating shaft 36 of the second synchronous pulley 32 respectively drive the first connecting rod 41 and the second connecting rod 42 to rotate, thereby driving the connecting rod arm 43 to move.

[0045] The second rotating shaft 36 of the second synchronous pulley 32 drives the positioning member 51 to rotate. When it rotates to 180 degrees, the positioning member 51 cooperates with the stroke stop sensor 52, causing the stroke stop sensor 52 to send a feedback signal to stop the rotary drive motor 2.

[0046] During this process, the first connecting rod 41 and the second connecting rod 42 drive the connecting rod arm 43 to translate to the blanking station 62 to blank the fuse.

[0047] An embodiment of a blanking translation mechanism of the present utility model has the advantages that it can achieve stable grasping and blanking of the fuse during translation, and has the problems of fast speed during blanking (especially for small parts such as fuses) and low costs for production, debugging, and subsequent maintenance.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
