Description

Technical Field

[0001] This utility model belongs to the technical field of transportation and loading devices, and specifically relates to an optical cap aligning device. Background Technology

[0002] Optical caps are core packaging components for TO-packaged optoelectronic devices and micro laser tubes. Their sealed ends house optical lenses, which must be arranged in a matrix with the openings facing upwards during subsequent assembly, testing, and packaging processes. The efficiency and precision of this arrangement directly determine the production yield and mass production capacity of the optical devices. Currently, optical cap arrangement is mainly divided into two methods: manual arrangement and automated arrangement equipment. Manual arrangement relies on operators placing the caps manually, which suffers from low efficiency, easy scratching of optical lenses, and a high rate of orientation errors, making it unsuitable for mass production. Existing automated arrangement equipment often uses bolted fastening for fixtures and vibration platforms. Changing models requires repeated disassembly and reassembly of multiple bolt sets, resulting in long changeover times and high equipment downtime. Furthermore, uneven bolt fastening forces can lead to gaps between the fixture and platform, preventing rigid synchronous vibration during high-frequency vibration, reducing arrangement accuracy and cap insertion yield, and potentially causing stripped threads in the platform's threads over time.

[0003] Existing solutions using conventional simple clips instead of bolts for fastening still have unresolved technical drawbacks: First, they lack self-locking and anti-loosening capabilities. During continuous high-frequency vibration operation, the clips are prone to springing back and loosening, causing relative displacement between the fixture and the platform. This can result in pipe caps falling off, optical surfaces being scratched and scrapped, or even equipment safety accidents caused by fixture detachment. Second, the consistency of locking force cannot be guaranteed. When manually operating bolts or simple clips, the locking force relies entirely on the operator's experience, easily leading to uneven force at multiple locking points. This causes warping and gaps on the contact surface between the fixture and the platform, resulting in asynchronous vibration transmission in different areas of the fixture. Consequently, the yield rate of pipe cap alignment fluctuates significantly, failing to meet the high-precision and high-consistency alignment production requirements for optical pipe caps. Third, the ease of operation is extremely poor with multi-fixture layouts. For double-headed, multi-slot row layouts, bolts or simple clips must be operated individually for each group, making it impossible to achieve rapid synchronous tightening and loosening, thus lengthening the operation time for fixture replacement. Meanwhile, existing fixtures mostly adopt a structure that separates and splices storage bins, flow channels, and rows of perforated plates. During high-frequency vibration, the vibration transmission consistency of each section is poor, which can easily lead to problems such as pipe cap stacking, material jamming, and flow channel blockage. Utility Model Content

[0004] The purpose of this invention is to provide an optical cap aligning device that can achieve stable locking of the fixture, ensure rigid synchronous vibration, improve alignment accuracy, and at the same time improve fixture changeover efficiency and production continuity, adapting to the needs of mass production and multi-specification optical caps.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An optical cap aligning device includes a vibration host, a horizontally positioned vibration platform fixedly connected to the power output end of the vibration host, at least one set of parallel alignment fixture carriers detachably mounted on the vibration platform, a storage bin and an alignment channel sequentially arranged on the alignment fixture carriers along the optical cap alignment conveying direction, a matrix alignment perforated plate arranged on the alignment channel, a mounting pad between the vibration platform and the alignment fixture carriers, and toggle clamps corresponding one-to-one with the alignment fixture carriers fixedly mounted on the edge of the mounting pads, with slidable clamps on the inner wall of the alignment fixture carriers facing the toggle clamps. The locking platform has a sliding direction parallel to the surface of the vibration platform. The toggle clamp includes a fixed base, a positioning pin, a toggle linkage, and an operating handle. The fixed base is fixedly connected to the mounting plate. There is a hinge point one between the operating handle and the positioning pin, a hinge point two between the operating handle and the toggle linkage, and a hinge point three between the toggle linkage and the fixed base. Hinge points one, two, and three can rotate with the operating handle to the same straight line position. At the same straight line position, the toggle linkage has no circumferential rotation allowance, and the positioning pin horizontally presses the locking platform, so that the locking platform forms a rigid fixation without relative displacement.

[0007] Furthermore, the vibration platform is equipped with two sets of mounting pads, which are arranged in parallel rows on the left and right. Each set of mounting pads can be detachably mounted with two sets of parallel row fixture bearing seats.

[0008] Furthermore, each set of jig carriers is equipped with a set of toggle clamps, which are arranged at the front end of the corresponding jig carrier along the optical cap conveying direction.

[0009] Furthermore, the positioning pin is designed as a rod, with one end hinged to the operating handle and the other end equipped with an adjusting screw. The end of the adjusting screw furthest from the positioning pin is fixedly connected to the locking platform.

[0010] Furthermore, a buffer elastic element is provided between the locking platform and the adjusting screw, and a limit slot is fixedly provided on the locking platform, with the buffer elastic element fixedly installed in the groove of the limit slot.

[0011] Furthermore, the locking platform includes an integrally formed sliding guide base plate and a locking top block body, with the locking top block body vertically fixed to the sliding guide base plate.

[0012] Furthermore, a groove is provided on the inner wall of the end of the jig bearing seat facing the toggle clamp. The extension direction of the groove is parallel to the axis of the positioning pin, and the sliding guide base plate is horizontally slidably embedded in the groove.

[0013] Furthermore, the storage bin is an open-type material trough integrally formed with the support seat of the entire jig, and a guide slope is provided at the bottom of the inner cavity of the storage bin.

[0014] Furthermore, the guide ramp is integrally equipped with an upward-extending spill-proof guard.

[0015] Furthermore, a limit stop is fixedly installed at one end of the entire jig support.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention employs a toggle-type clamp with dead-point self-locking characteristics. Dead-point self-locking is achieved by rotating hinge points one, two, and three to the same straight-line position. In the locked state, the toggle linkage has no circumferential rotational allowance, forming an irreversible mechanical self-lock. This effectively prevents relative displacement of the fixture, pipe cap spillage and scratches, and fixture detachment, improving the stability and safety of equipment operation. The toggle-type clamp allows for a one-step locking and unlocking process with just the operating handle, shortening equipment downtime and solving the pain points of complex and time-consuming multi-fixture changeover operations. It is particularly suitable for the frequent changeover production needs of optical pipe caps in multiple specifications, small batches, and multiple batches, improving equipment production efficiency and large-scale capacity. Simultaneously, the locking force of the toggle-type clamp can be evenly transmitted along the contact surface between the fixture support and the mounting plate, solving the problems of uneven bolt locking force and uncontrollable simple buckle locking force leading to fixture warping and gaps on the contact surface, significantly improving the accuracy of pipe cap alignment.

[0027] Example 1

[0028] like Figures 1-6 As shown, the optical cap aligning device includes a vibration host 1. A horizontally positioned vibration platform is fixedly connected to the power output end of the vibration host 1. At least one set of parallel alignment fixture carriers 3 are detachably mounted on the vibration platform. Storage bins 4 and alignment channels 5 are sequentially arranged on the alignment fixture carriers 3 along the optical cap alignment conveying direction. A matrix alignment perforated plate is provided on the alignment channels 5. A mounting pad 2 is provided between the vibration platform and the alignment fixture carriers 3. Toggle clamps corresponding to the alignment fixture carriers 3 are fixedly mounted on the edge of the mounting pad 2. A locking platform 6, directly opposite the toggle clamps, is slidably arranged on the inner wall of the alignment fixture carriers 3. The sliding direction is parallel to the platform surface of the vibration platform; the toggle clamp includes a fixed base 7, a positioning pin 8, a toggle connecting rod 9 and an operating handle 10. The fixed base 7 is fixedly connected to the mounting pad 2. A hinge point 11 is provided between the operating handle 10 and the positioning pin 8, a hinge point 2 12 is provided between the operating handle 10 and the toggle connecting rod 9, and a hinge point 3 13 is provided between the toggle connecting rod 9 and the fixed base 7. The hinge points 11, 22 and 3 can rotate with the operating handle 10 to the same straight line position. At the same straight line position, the toggle connecting rod 9 has no circumferential rotation allowance. The positioning pin 8 horizontally presses the locking platform 6, so that the locking platform 6 forms a rigid fix with no relative displacement.

[0029] The vibration platform is equipped with two sets of mounting pads 2, which are arranged in parallel rows on the left and right. Each set of mounting pads 2 can be detachably mounted with two sets of parallel row fixture bearing seats 3.

[0030] Each set of jig carriers 3 is equipped with a set of toggle clamps, which are arranged at the front end of the corresponding jig carrier 3 along the optical cap conveying direction.

[0031] The positioning pin 8 is designed in the form of a rod. One end of the positioning pin 8 is hinged to the operating handle 10, and the other end of the positioning pin 8 is provided with an adjusting screw. The end of the adjusting screw away from the positioning pin 8 is fixedly connected to the locking table 6.

[0032] A buffer elastic element 14 is provided between the locking platform 6 and the adjusting screw. A limit groove 15 is fixedly provided on the locking platform 6, and the buffer elastic element 14 is fixedly provided in the groove of the limit groove 15.

[0033] The locking platform 6 includes an integrally formed sliding guide base plate 601 and a locking top block body 602, with the locking top block body 602 vertically fixed on the sliding guide base plate 601.

[0034] The inner wall of the bearing seat 3 of the row fixture facing the toggle clamp has a groove. The extension direction of the groove is parallel to the axis of the positioning pin 8. The sliding guide base plate 601 is horizontally slidably embedded in the groove.

[0035] The storage bin 4 is an open-type material trough integrally formed with the row fixture support 3, and the bottom of the inner cavity of the storage bin 4 is provided with a guide slope.

[0036] The guide ramp is integrally equipped with an upward-extending anti-spillage guard.

[0037] A limit stop 16 is fixedly installed at one end of the bearing seat 3 of the row fixture.

[0038] Working process and principle:

[0039] I. Fixture Installation Stage

[0040] According to the specifications and models of the optical caps to be aligned, select the corresponding matching matrix alignment plate and place the matrix alignment plate stably on the alignment flow channel 5 of the alignment fixture carrier 3.

[0041] II. Locking and Fixing Stage

[0042] When the operating handle 10 is moved, the operating handle 10 simultaneously drives hinge point 11 and hinge point 2 to rotate in a circle, thereby pulling the toggle link 9 to rotate around hinge point 3. When hinge point 11, hinge point 2, and hinge point 3 13 rotate with the operating handle 10 to the same straight line position, the toggle link 9 reaches the mechanical dead point position. At this time, the toggle link 9 has no circumferential rotation margin, forming an irreversible dead point self-locking structure.

[0043] During this process, the positioning pin 8, which is hinged to the operating handle 10 through hinge point 11, pushes forward horizontally. The adjusting screw at its front end pushes the locking table 6 to slide horizontally along the slide groove through the buffer elastic element 14 in the limiting slot 15, so that the sliding guide base plate 601 of the locking table 6 is completely pressed against the matrix alignment hole plate to form a rigid fixation without relative displacement. The entire locking process can be completed in one step by simply turning the operating handle 10, solving the pain points of traditional bolt locking which requires repeated tightening of multiple bolts and time-consuming changes; the dead-point self-locking structure can completely resist the reverse impact force brought by the high-frequency vibration of the vibration host 1, and will not have the problem of rebound and loosening, avoiding the risk of fixture slippage and pipe cap spillage and scratches, ensuring the stability and safety of equipment operation; the buffer elastic element 14 can evenly transmit the locking force along the contact surface of the alignment fixture support 3 and the mounting pad 2, solving the problem of fixture warping and gaps in the contact surface caused by uneven bolt locking and simple buckle locking forces, and greatly improving the alignment accuracy of optical pipe caps; the limiting block 16 at the end of the alignment fixture support 3 can limit the sliding stroke of the locking table 6 and prevent the locking table 6 from falling out of the alignment fixture support 3.

[0044] III. Automated Column Formation Stage

[0045] The scattered optical caps to be aligned are poured into the storage bin 4, and the vibration host 1 is started. The vibration host 1 outputs high-frequency micro-amplitude vibration, and the vibration energy is evenly and synchronously transmitted to the alignment fixture support seat 3 through the mounting pad 2. The optical caps in the storage bin 4 slide into the matrix alignment plate in the alignment channel 5 in an orderly and uniform manner. Under the action of continuous high-frequency vibration, the optical caps vibrate on the matrix alignment plate and finally complete the alignment operation of the optical caps in a uniform posture with the opening facing upward.

[0046] The storage bin 4 and the aligning fixture support 3 are integrally formed structures without any assembly gaps between the parts, which effectively avoids problems such as pipe cap stacking, material jamming, and flow channel blockage, and improves the stability of continuous operation. The circumferential anti-spillage baffles of the storage bin 4 can prevent pipe caps from splashing out during high-frequency vibration, further reducing the risk of material loss and scratches on the optical lens surface.

[0047] IV. Fixture Replacement Stage

[0048] When it is necessary to change to optical caps of different specifications for production, simply reverse the operating handle 10 of the corresponding fixture to release the dead-point self-locking state of the toggle clamp, and then directly remove the matrix alignment plate in the alignment channel 5. After replacing it with the matrix alignment plate of the corresponding specification, repeat the above pre-positioning and locking steps to quickly complete the matrix alignment plate changeover. The entire process requires no disassembly or assembly of any bolts, reduces the equipment's ineffective standby time, and improves production continuity and flexibility.
