Detailed Implementation

[0028] The present invention will now be described in conjunction with specific embodiments.

[0029] Example 1, as Figures 1 to 3 As shown, an automatic pin trimming device includes a frame 1, on which an automatic trimming component 2 and a CCD vision inspection component 3 are mounted.

[0030] Among them, such as Figures 1 to 3 As shown, the frame 1 is also equipped with a feeding conveyor belt 41, an inspection placement table 5, and a finished product discharge conveyor belt 42 arranged sequentially at intervals along the Y-axis. An inspection and handling assembly 6 is installed above the inspection placement table 5. The CCD vision inspection assembly 3 includes two CCD vision inspection modules 31 arranged opposite each other on both sides of the inspection placement table 5.

[0031] Furthermore, such as Figures 1 to 3 As shown, the frame 1 is also equipped with an X-axis platform 7 and a return inspection conveyor belt 43 that move along the X-axis direction respectively. A trimmed transport assembly 8 is installed between the X-axis platform 7 and the return inspection conveyor belt 43. An NG product collection device 9 is installed below the trimmed transport assembly 8. The unloading end of the return inspection conveyor belt 43 is close to the loading end of the finished product discharge conveyor belt 42.

[0032] Furthermore, such as Figures 1 to 3 As shown, the X-axis stage 7 includes an X-axis drive linear module 71 and a workpiece clamp 72 mounted on the drive end of the X-axis drive linear module 71. The movement path of the X-axis stage 7 is determined by the working position of the automatic trimming component 2. When the X-axis stage 7 is in the initial position, the workpiece clamp 72 is close to the unloading end of the feed conveyor belt 41.

[0033] It should be explained that the feeding conveyor belt 41 of the first embodiment can be connected to an upper computer or manually fed. When working, the feeding conveyor belt 41 orderly feeds the workpiece to the discharging end of the feeding conveyor belt 41, and makes the workpiece enter the grabbing position of the detection and carrying assembly 6 in sequence.

[0034] The automatic PIN pin trimming device of the first embodiment will be described in detail below in combination with a specific working process. Specifically:

[0035] Step a, the detection and carrying assembly 6 grabs the workpiece from the discharging end position of the feeding conveyor belt 41 and moves the workpiece to the detection and placement table 5;

[0036] Step b, the CCD visual detection assembly 3 visually detects the PIN pin of the workpiece through two oppositely arranged CCD visual detection modules 31 to detect and judge whether the PIN pin of the workpiece is deformed;

[0037] Step c, when the workpiece detected by the CCD visual detection assembly 3 is an OK product, the detection and carrying assembly 6 grabs and moves the workpiece product on the detection and placement table 5 to the finished product discharging conveyor belt 42 to send the finished product workpiece out through the finished product discharging conveyor belt 42;

[0038] When the workpiece detected by the CCD visual detection assembly 3 is an NG product, the detection and carrying assembly 6 grabs and moves the NG product workpiece on the detection and placement table 5 to the workpiece clamp 72 of the X-axis stage 7 located at the initial position;

[0039] Step d, the X-axis driving linear module 71 of the X-axis stage 7 moves and moves the NG product workpiece clamped and fixed by the workpiece clamp 72 to the working position of the automatic trimming assembly 2, and the automatic trimming assembly 2 trims the PIN pin of the NG product workpiece;

[0040] Step e, after the automatic trimming assembly 2 completes the PIN pin trimming work of the NG product workpiece, the X-axis stage 7 moves the trimmed workpiece to the grabbing position of the trimmed carrying assembly 8, and the trimmed carrying assembly 8 grabs and moves the trimmed workpiece to the re-inspection conveyor belt 43, and the re-inspection conveyor belt 43 conveys the trimmed workpiece to the discharging end position;

[0041] Step f, after the re-inspection conveyor belt 43 conveys the trimmed workpiece to the discharging end position, the detection and carrying assembly 6 moves and grabs the trimmed workpiece to the detection and placement table 5 to re-detect the trimmed workpiece by the CCD visual detection assembly 3;

[0042] When the trimmed workpiece is detected as an OK product, the detection and carrying assembly 6 grabs and moves the workpiece product on the detection and placement table 5 to the finished product discharging conveyor belt 42 to send the finished product workpiece out through the finished product discharging conveyor belt 42;

[0043] When a repaired workpiece is detected as NG, the workpiece that is confirmed as NG again after repair is picked up by the inspection and handling component 6 and transferred to the X-axis stage 7. It is then transferred by the X-axis stage 7 to the picking position of the repaired handling component 8, and then picked up by the repaired handling component 8 and transferred to the NG collection device 9 for collection.

[0044] It should be emphasized that the automatic pin trimming device in this embodiment only uses a single CCD vision inspection component 3 to detect the workpiece; compared with the prior art, this structural design is simpler.

[0045] It should be further emphasized that, for the automatic pin trimming equipment of this embodiment, the workpieces that are confirmed as NG after trimming are directly collected by the NG collection device 9, and will not be repeatedly trimmed in a cyclical manner; compared with the prior art, the automatic pin trimming equipment of this embodiment has higher working efficiency.

[0046] In summary, the automatic pin trimming device of this embodiment has the advantages of novel structural design and high working efficiency through the above structural design.

[0047] Example 2, as Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the detection and handling component 6 includes a first Y-axis drive linear module 61 mounted on the frame 1 and moving along the Y-axis direction. The drive end of the first Y-axis drive linear module 61 is equipped with a first lifting drive cylinder 62. The drive end of the first lifting drive cylinder 62 is equipped with a first lifting movable frame 63. The first lifting movable frame 63 is equipped with a first gripping mechanism 641 and a second gripping mechanism 642 arranged at intervals along the Y-axis direction.

[0048] Specifically, such as Figure 4 As shown, the first gripping mechanism 641 and the second gripping mechanism 642 respectively include a horizontal drive cylinder 643 that moves horizontally along the X-axis direction, a rotary drive cylinder 644 mounted on the drive end of the horizontal drive cylinder 643, a suction cup mounting bracket 645 mounted on the drive end of the rotary drive cylinder 644, and a workpiece suction cup 646 mounted on the suction cup mounting bracket 645. Each horizontal drive cylinder 643 is respectively mounted on the first lifting movable frame 63.

[0049] For the detection and handling component 6 in this embodiment 2, the first Y-axis drive linear module 61 is used to drive the first lifting movable frame 63 to move horizontally, and the first lifting drive cylinder 62 is used to drive the first lifting movable frame 63 to move vertically. That is, the first Y-axis drive linear module 61 and the first lifting drive cylinder 62 drive the first clamping mechanism and the second clamping mechanism to move synchronously.

[0050] Specifically, when the first grabbing mechanism 641 grabs the workpiece at the lower end of the feeding conveyor belt 41, the first Y-axis driving linear module 61 drives the first grabbing mechanism 641 to move to the position above the lower end of the feeding conveyor belt 41, and then the first lifting driving cylinder 62 operates and drives the first grabbing mechanism 641 to move downward to the grabbing position, and the first grabbing mechanism 641 grabs the workpiece through the lower workpiece grabbing disc; after the first grabbing mechanism 641 completes the grabbing of the workpiece at the lower end of the feeding conveyor belt 41, the first Y-axis driving linear module 61 and the first lifting driving cylinder 62 cooperate and drive the workpiece grabbed by the first grabbing mechanism 641 to move to the detection placement table 5.

[0051] When the workpiece on the workpiece placement table is detected and confirmed as an NG product, the first Y-axis driving linear module 61 and the first lifting driving cylinder 62 cooperate and drive the workpiece suction cup 646 of the first grabbing mechanism 641 to grab the NG product workpiece on the detection placement table 5, and then the horizontal driving cylinder 643 operates and drives the workpiece suction cup 646 and the grabbed workpiece to move towards the X-axis table 7 side, and then the rotary driving cylinder 644 operates and drives the grabbed NG product workpiece to rotate by 90 degrees, and finally the first grabbing mechanism 641 places the NG product workpiece on the workpiece clamp 72 of the X-axis table 7 at the initial position.

[0052] When the second grabbing mechanism 642 grabs the workpiece that has been detected and confirmed as an OK product, the first Y-axis driving linear module 61 and the first lifting driving cylinder 62 cooperate and drive the second grabbing mechanism 642 to grab the OK product workpiece from the detection placement table 5, and then move the OK product workpiece to the finished product discharge conveyor belt 42.

[0053] When the second grabbing mechanism 642 grabs the finished workpiece after trimming that is conveyed to the lower end position by the re-inspection conveyor belt 43, the horizontal driving cylinder 643 first drives the workpiece suction cup 646 to move towards the re-inspection conveyor belt 43 side, and then the first Y-axis driving linear module 61 and the first lifting driving cylinder 62 cooperate and drive the workpiece suction cup 646 to adsorb and grab the finished workpiece after trimming at the lower end position of the re-inspection conveyor belt 43, and then the rotary driving cylinder 644 operates and drives the finished workpiece after trimming to rotate by 90 degrees, and finally the first Y-axis driving linear module 61 and the first lifting driving cylinder 62 cooperate and drive the finished workpiece after trimming to be placed on the detection placement table 5 for detection.

[0054] As shown in FIG. 3, the embodiment one includes a first Y-axis driving linear module 61, a first lifting driving cylinder 62, a first horizontal driving cylinder 63, a first rotary driving cylinder 64, and a first grabbing mechanism 641. Figures 1 to 3 As shown in FIG. 3, the embodiment one includes a first Y-axis driving linear module 61, a first lifting driving cylinder 62, a first horizontal driving cylinder 63, a first rotary driving cylinder 64, and a first grabbing mechanism 641.

[0055] In the working process of the post-trimming conveying assembly 8 of the third embodiment, when the workpiece is moved to the grabbing position by the X-axis carrier 7, the second Y-axis driving linear module 81 drives the post-trimming workpiece clamping jaw 83 to move above the grabbing position, and then the second lifting driving cylinder 82 drives the post-trimming workpiece clamping jaw 83 to move downward and make the post-trimming workpiece clamping jaw 83 grab the workpiece; when the grabbed workpiece is a post-trimming workpiece which is not detected, the second Y-axis driving linear module 81 and the second lifting driving cylinder 82 cooperate to move the workpiece to the re-inspection conveying belt 43; when the grabbed workpiece is a post-trimming workpiece which is detected and confirmed as an NG product again, the second Y-axis driving linear module 81 and the second lifting driving cylinder 82 cooperate to move the workpiece to the NG product collecting device 9.

[0056] As shown in the fourth embodiment, the fourth embodiment is different from the first embodiment in that the automatic trimming assembly 2 comprises two trimming modules 21 which are arranged opposite to each other on both sides of the X-axis carrier 7. Figure 5

[0057] The trimming module 21 comprises a horizontal driving linear module 22 which is arranged on the rack 1 and moves along the X-axis direction, a driving end of the horizontal driving linear module 22 is arranged with a lifting driving linear module 23 which moves vertically, and a driving end of the lifting driving linear module 23 is arranged with a PIN leg bending block 24.

[0058] In the process of trimming the PIN legs on both sides of the workpiece by the automatic trimming assembly 2, the horizontal driving linear module 22 and the lifting driving linear module 23 cooperate to make the PIN leg bending block 24 align with the PIN legs, and then the PIN leg bending block 24 is bent by the reciprocating movement of the lifting driving linear module 23 to realize the trimming and flattening of the PIN legs.

[0059] The above is only the preferred embodiment of the present application, and for the ordinary skilled in the art, the specific implementation and application range can be changed according to the idea of the present application, and the content of the specification should not be understood as the limitation of the present application.​
