Description

Technical Field

[0001] The invention relates to the technical field of optical module dispensing, and in particular to an optical module positioning and anti-bias dispensing device. Background Art

[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include transmitting and receiving parts. The function of the optical module is to convert electrical signals into optical signals at the transmitting end. After transmission through optical fiber, the receiving end converts the optical signals into electrical signals. However, the optical module needs to be placed in the glue dispensing groove first during assembly, and then glue is dispensed through the glue dispensing structure. The glue dispensing groove in the prior art is a limited opening setting. However, due to the overall movement of the equipment, vibration is inevitable, which can easily cause the electronic components to shake and cause glue dispensing offset problems. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN220514594U discloses a dispensing device for optical module processing that prevents deviation, including a box body, a first electric push rod embedded in the back of the inner cavity of the box body, and a fixed box fixedly connected to the telescopic end of the first electric push rod. The utility model constructs a dispensing device for optical module processing that prevents deviation by setting a box body, a first electric push rod, a fixed box, a dual-axis motor, a first threaded rod, a first threaded sleeve, a clamping plate, an adjustment component, a second electric push rod, and a hot melt head. The first electric push rod can be used to push the fixed box to move forward and backward, so that the optical module can be easily installed on the fixed box. The dual-axis motor, the first threaded rod, the first threaded sleeve, and the clamping plate can be used to clamp and position the optical module, so as to avoid shaking during the processing, dispensing deviation, and affecting the processing effect. Finally, the hot melt head can be driven to move its position by setting the adjustment component, so as to improve the dispensing efficiency.

[0004] Although the equipment in the above document can clamp and fix the optical module and improve the shaking resistance during dispensing, it still has obvious defects in actual use, such as: The overall size of the optical module is very small. Generally, the dispensing process is carried out in batches. However, the equipment in the document can only dispense glue to a single optical module at a time, which will affect the production efficiency in actual production. In addition, cumbersome installation and disassembly processes are required before and after each dispensing, which is inconvenient for the staff to use. Therefore, an optical module positioning and anti-bias dispensing device is now designed to improve dispensing efficiency to solve such defects. Summary of the invention

Beneficial Effects

[0014] The present invention provides an optical module positioning and anti-bias glue dispensing device. Compared with the existing technology, it has the following beneficial effects: (1) The optical module positioning and anti-biased glue dispensing device uses a feed protection mechanism and a glue dispensing positioning mechanism in combination. The two mechanisms can dispense glue to multiple optical modules at one time. In the process of dispensing, the linkage between the structures can be used to allow the upper mold cover to descend and dock with the lower mold plate for protection, thereby reducing the shaking during dispensing. At the same time, after the dispensing is completed, the lower mold plate can be shoveled up in the linkage state and the material can be quickly unloaded. The whole process does not require the staff to perform too much operation, which not only improves the dispensing efficiency, but also facilitates the use of the staff.

[0015] (2) The optical module positioning and anti-biased glue dispensing device is provided with a lower mold plate by opening a rectangular groove on the top of the load-bearing guide slide, and an inclined pressure rod is installed on the top of the load-bearing guide slide. It is used in conjunction with a round pressure column and an upper mold cover. The arrangement of these structures can allow the round pressure column to press the inclined pressure rod during the descent of the electric telescopic rod, thereby driving the lower mold plate to move backward to feed the material. It can also stop moving after reaching the specified position and allow the upper mold cover to press down and dock with the lower mold plate, thereby fixing the optical module inside the lower mold plate, ensuring that it will not shake or deviate during the glue dispensing process, thereby improving the quality of glue dispensing, and does not require the staff to perform tedious fixing and installation procedures, which is satisfactory for current use.

[0016] (3) The optical module positioning and anti-bias glue dispensing device is configured by installing a double sliding sleeve frame on the surface of the electric telescopic rod, and allowing the double sliding sleeve frame to be slidably connected to the load-bearing horizontal plate, and used in conjunction with a vertical pressure column and an arc correction block. The arrangement of these structures can allow the load-bearing horizontal plate to follow the descent, and press the vertical pressure column to insert into the positioning socket to fix the lower mold plate as a whole. At the same time, when the subsequent rectangular guide slide seat drives the linear motor to move forward and backward, the double sliding sleeve frame can be slid and guided through the load-bearing horizontal plate, which will not cause offset blockage during the operation of the equipment, thereby improving the stability during glue dispensing.

[0017] (4) The optical module positioning and anti-biased glue dispensing device is used by arranging a shovel bevel frame at the bottom of the glue dispensing operation box, and is used in conjunction with a sloping bottom plate and a curved horizontal plate. The arrangement of these structures enables the curved horizontal plate to squeeze the inclined bottom plate to push the shovel bevel frame up when the lower mold plate moves forward after completing the glue dispensing, so that the shovel bevel frame lifts the lower mold plate for sliding unloading. When the lower mold plate moves backward to feed the material, the curved horizontal plate can be squeezed and moved upward, so that it will not conflict with the inclined bottom plate, thereby ensuring smooth feeding and discharging of the material and improving the overall efficiency.

The rear part of the load-bearing guide slide plate 103 is fixedly connected with a return rod 122 through a fixed block, and the bottom end of the return rod 122 passes through the downward movement opening 121 and extends to the lower part of the glue dispensing operation box 101. The surface of the return rod 122 and the lower part of the glue dispensing operation box 101 are slidably installed with an arc-shaped horizontal plate 123 used in conjunction with the inclined bottom plate 119. A rectangular guide slide seat 124 is fixedly connected to the upper part between the front and rear of the inner cavity of the glue dispensing operation box 101, and a linear motor 125 is slidably installed on the surface of the rectangular guide slide seat 124. An upward movement opening 126 is opened at the top of the glue dispensing operation box 101.

[0023] When in use, first place a number of optical modules in the groove inside the lower mold plate 106, then place the lower mold plate 106 inside the rectangular groove 104, and then connect the feed pipe to the two glue dispensing mechanisms 203, then start the electric telescopic rod 201, and after the electric telescopic rod 201 is started, it pushes the upper pressure plate 202 and the double sliding frame 204 to descend synchronously, and after the double sliding frame 204 descends, it will pull the return rod 122 and the U-shaped frame 114 to descend, and when the U-shaped frame 114 descends, it will drive the two round pressure columns 115 The two inclined pressure rods 110 are squeezed, and after the two inclined pressure rods 110 are squeezed, the load-bearing guide slide plate 103 will move backward under the limit of the hollow slide frame 102 until the round pressure column 115 contacts the vertical part of the inclined pressure rod 110, and the load-bearing guide slide plate 103 moves to the final position and is located directly below the upper mold cover 208. Then, as the electric telescopic rod 201 continues to descend, the load-bearing cross plate 112 will push the arc correction block 209 to squeeze the lower mold plate 106 to correct its extrusion position, and then the upper mold cover 208 and The top of the lower mold plate 106 is butted and pressed to fix the optical module, and at the same time, the vertical pressure column 206 is inserted into the inner side of the positioning socket 109 to position the upper mold cover 208 and the lower mold plate 106. At this time, the bottom end of the dispensing mechanism 203 is still a distance away from the upper mold cover 208, but the vertical pressure column 206 is pressed by the curved sliding plate 205 to drive the fourth spring 210 to always be inserted into the positioning socket 109. At this time, the electric telescopic rod 201 drops again, which will cause the load-bearing cross plate 112 to push the dispensing mechanism 203 to contact the optical module and perform dispensing. The short-distance lifting and lowering of the glue dispensing mechanism 203 will not cause the vertical pressure column 206 to be pulled out from the positioning socket 109 under the action of the elastic force of the fourth spring 210. At the same time, after the linear motor 125 is started, it can drive the electric telescopic rod 201 and the glue dispensing mechanism 203 to move back and forth under the guidance of the rectangular guide slide seat 124 to dispense glue for the remaining optical modules. When the electric telescopic rod 201 moves back and forth, the sliding connection between the double sliding sleeve frame 204 and the load-bearing cross plate 112 can ensure that the upper mold cover 208 always remains in a downward pressed state without displacement.

[0024] Please refer to Figure 8, showing the overall structure of the dispensing positioning mechanism 2, the dispensing positioning mechanism 2 includes an electric telescopic rod 201. The electric telescopic rod 201 is in a slow state after being pre-set to rise and fall. The electric telescopic rod 201 is fixedly installed on the left side of the linear motor 125 through a fixing plate, and the electric telescopic rod 201 is located on the inner side of the upper shift opening 126. The bottom end of the electric telescopic rod 201 is fixedly connected to an upper pressing plate 202. Both sides of the top of the upper pressing plate 202 are fixedly connected to the dispensing mechanism 203 through a water opening. The lower surface of the electric telescopic rod 201 is fixedly connected to the upper pressing plate 202. A double sliding sleeve frame 204 is fixedly connected to the top, and both ends of the double sliding sleeve frame 204 are slidably connected to the load-bearing horizontal plate 112 on the same side. A curved sliding sleeve plate 205 is fixedly connected to the front end of the load-bearing horizontal plate 112. A vertical pressure column 206 used in conjunction with the positioning socket 109 is slidably installed on the inner side of the curved sliding sleeve plate 205. A round-mouth plug plate 207 is slidably installed on the surface of the vertical pressure column 206. An upper mold cover 208 used in conjunction with the lower mold plate 106 is fixedly connected between the two round-mouth plug plates 207 through a fixed block. A plurality of grooves for dispensing glue are arranged on the top of the upper mold cover 208. A fourth spring 210 is sleeved on the surface of the vertical pressure column 206, and arc correction blocks 209 are fixedly connected on both sides of the surface of the upper mold cover 208.

[0025] After the dispensing is completed, the electric telescopic rod 201 pulls the upper pressure plate 202 to rise. As the electric telescopic rod 201 and the curved sliding plate 205 rise, the double sliding frame 204 will also drive the load-bearing cross plates 112 on both sides to rise synchronously. After the load-bearing cross plate 112 rises, the vertical pressure column 206 will be pulled out from the inner side of the positioning socket 109, and at the same time, the upper mold cover 208 will be separated from the top of the lower mold plate 106, until the round pressure column 115 slowly separates from the inclined pressure rod 110, and the load-bearing guide slide plate 103 drives the lower mold plate 106 to move forward slowly under the elastic force of the first spring 108. At this time, the arc surface cross plate 123 is driven forward to push and squeeze the inclined bottom plate 119, so that the inclined bottom plate 119 uses the top guide rod 117 to push the shoveling material inclined frame 118 to rise a distance, so that the shoveling material The rear end of the inclined frame 118 is slightly higher than the shovel slot 105. As the load-bearing guide slide plate 103 continues to move forward, the shovel inclined frame 118 will lift the lower mold plate 106 out of the rectangular slot 104, and finally make the lower mold plate 106 slide down along the shovel inclined frame 118 to discharge the material. When the curved cross plate 123 moves to the front, it is separated from the inclined bottom plate 119. At this time, the shovel inclined frame 118 descends under the elastic force of the third spring 120, and then the lower mold plate 106 with the optical module re-placed is placed on the inner side of the rectangular slot 104. When the electric telescopic rod 201 pushes the curved sliding sleeve plate 205 to descend again, and the lower mold plate 106 moves backward again, the curved cross plate 123 will be squeezed by the inclined bottom plate 119 and will rise without hard conflict with the inclined bottom plate 119.
