Specific embodiments

[0024] The following further elaborates the utility model in conjunction with specific embodiments.

[0025] As Figures 1 - 3 shown, an inductive automatic blanking optical fiber ceramic ferrule press includes a frame 1. An ejector rod propulsion mechanism 5 is arranged on the frame 1. The ejector rod propulsion mechanism 5 is connected to the material placement mechanism 4. A blanking propulsion mechanism 3 is arranged on the side of the material placement mechanism 4. A blanking port 11 is formed at the lower part of the material placement mechanism. The blanking propulsion mechanism is connected to the material bearing plate 16 through a transverse movement mechanism 9. After the material bearing plate 16 is drawn out from the material placement mechanism 4, the processed products on the material bearing plate 16 fall into the blanking port. The ceramic ferrule part and the V-groove part are pressed and assembled by the one-time propulsion of the ejector rod propulsion mechanism. After processing, the blanking propulsion mechanism 3 executes product blanking, realizing the automatic blanking process after product assembly.

[0026] In one embodiment, the ejector rod propulsion mechanism 5 includes a translation drive ejector rod 14. One end of the translation drive ejector rod 14 is connected to the ejector rod connection seat 20, and the other end is connected to the material crimping ejector rod 19. The material crimping ejector rod 19 is arranged in the central groove of the material placement seat. The ceramic ferrule part is mainly pushed inward by the material crimping ejector rod pressed by the translation drive ejector rod 14 of the ejector rod propulsion mechanism 5.

[0027] Specifically, a V-groove part positioning part and a ceramic ferrule part positioning part to be pressed are arranged at the front part of the central groove of the material placement seat. The V-groove part positioning part forms a limit and clamping for the V-groove part 12. A hollow groove for the material bearing plate is formed below the V-groove part positioning part on the material placement seat. Forming the positioning part can facilitate the accurate feeding position on the one hand, and ensure the reliability and stability of the positioning after feeding on the other hand. The assembly is completed by one-time pressing, and the V-groove part is reliably fixed on the V-groove part positioning part.

[0028] In one embodiment, a connecting shaft and a bearing 21 are provided at the outer end of the ejector rod connecting seat 20, and the outer end of the bearing abuts against the ejector rod advancing cam 6. The ejector rod advancing cam 6 forms a concave arc locally to match the outer circumference of the bearing. When the ejector rod advancing cam 6 rotates, it disengages from the bearing, triggering the forward advancement of the ejector rod connecting seat 20.

[0029] In one embodiment, the ejector rod advancing cam 6 is driven to rotate by the main drive motor 2. The ejector rod advancing cam 6 forms a limiting groove on the inner side, and further includes a motor limiting device 7. The motor limiting device 7 includes an extension arm 15, and a convex block is formed at the inner end of the extension arm 15 to match the limiting groove. By providing the motor limiting device, it is ensured that the stroke of the motor triggers an action within a controllable range. A motor tightening and loosening adjustment nut 10 is also provided on one side of the frame platform.

[0030] Specifically, a laser sensing device 8 is provided on the side of the translation drive ejector rod 14. The laser sensing device 8 can be a laser probe. By detecting the forward advancement of the ejector rod with the laser probe, a signal is given to the blanking advancement mechanism to perform subsequent actions.

[0031] Specifically, a laser sensing device is provided at the rear of the motor limiting device 7. The sensing device is used to detect whether the action execution of the motor limiting device 7 is within the normal range.

[0032] Specifically, guide rods 22 are provided on both sides of the translation drive ejector rod on the ejector rod connecting seat. Springs 17 and linear bearings 18 are provided on both the translation drive ejector rod and the material pressing ejector rod. By providing the guide rods, it is ensured that the ejector rod advancement mechanism advances and compresses components along a predetermined path.

[0033] Specifically, the end of the translation drive ejector rod forms an end that is snapped into the central hollow groove of the ejector rod connecting seat, and the outer end of the material pressing ejector rod forms an end that abuts against the translation drive ejector rod.

[0034] As Figure 4 shown, in order to facilitate the overall equipment to process more different types of parts, the material placement mechanism 4 can be set in multiple different models. The main difference between different models lies in that the overall design of the V-groove part positioning portion can better and perfectly match the V-groove part, ensuring the smooth progress of assembly. The rest of the material placement mechanism is designed as a general module, so it can be integrally disassembled and replaced on the frame.

[0035] The overall working process of the present utility model is as follows: After the equipment is started, the V-groove part and the ceramic ferrule part 13 are manually placed into the corresponding positioning parts of the material placing seat. The main drive motor is started to drive the ejector rod to push the cam to rotate. The translation drive of the ejector rod advancing mechanism drives the ejector rod to push the material crimping ejector rod to move forward to push the ceramic ferrule to match with the V-groove part. During the process of the translation drive ejector rod advancing forward, the laser induction probe detects a signal and drives the material bearing plate of the blanking advancing mechanism to move outwards and extract. When the product has no bearing, it naturally falls into the blanking port for centralized collection.

[0036] It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.
