Description

Technical Field

[0001] The utility model belongs to the technical field of dispensing workpiece jigs, and relates to a tooling jig for transformer dispensing. Background Technique

[0002] With the rapid development of the electronic manufacturing industry, PCB transformers have been widely used in various electronic devices due to their high performance, small size and light weight. In the production process of PCB transformers, the dispensing process is a key step to ensure the stable connection of internal components and excellent electrical performance of the transformers. The PCB transformer dispensing process mainly involves precisely injecting adhesives such as epoxy resin glue into the transformer to achieve tight connection between components. Due to the importance of transformers in electronic devices and the complexity of their structures, the accuracy requirements for the dispensing process are very high.

[0003] As a core component of electronic components, PCB transformers have different sizes, shapes and heights, and this diversity poses great challenges to the dispensing process. Although traditional dispensing tooling jigs have solved the problem of adapting to transformers of different models and sizes to a certain extent, they often seem powerless when faced with transformers with different heights. The height difference not only affects the pressing effect of the fixture on the top of the transformer, but also directly relates to the uniformity of dispensing and the performance of the transformer. In addition, if the upper pressing plate cannot completely press the top of the transformer, then when injecting glue, the glue may be unevenly distributed due to uneven pressure, which will in turn affect the tight connection between components and the overall performance of the transformer. Therefore, a tooling jig for transformer dispensing is needed to solve the above problems. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Next, in combination with the attached Figures 1 - 6 A further detailed description will be made of the specific embodiments of the present utility model.

[0026] As Figures 1 - 6 shown, the present utility model includes an upper layer plate 1 and a lower layer plate 2. The front parts of the upper layer plate 1 and the lower layer plate 2 are rotatably connected by a hinge. The rotation axis of the hinge is located on the upper side of the upper layer plate 1, so that when the upper layer plate 1 rotates downward and buckles, the applied pressing force is more uniform. In order to achieve the purpose of conveniently arranging and fixing transformers evenly, a plurality of placement grooves 3 are opened on the upper side of the lower layer plate 2. A sliding adjusting rod 4 connected to the lower layer plate 2 is provided on the rear side wall of each placement groove 3. A contact block 5 is fixedly connected to the front side of each adjusting rod 4. A clamping spring 6 is provided between each contact block 5 and the rear side wall of the placement groove 3. A support block 7 is fixedly connected to the front side wall of each placement groove 3. Pressing rods 8 corresponding to the placement grooves 3 one by one are provided on the upper layer plate 1. A movable pressing block 9 is provided on the lower side of each pressing rod 8;

[0027] It should be noted that the transformer is a planar transformer, which consists of a magnetic core and a PCB board. The magnetic core and the PCB board need to be arranged longitudinally, and then glue is dropped between them and they are clamped. When in use, the upper layer board 1 can be first turned upwards to open, and then the glued magnetic core and PCB board are arranged in the placement groove 3 in sequence. At this time, two adjacent magnetic cores in the front and back will be attracted to each other under the action of magnetic force. The contact block 5 is pushed by the clamping spring 6 to contact the side of the last transformer. At this time, the frontmost transformer abuts against the support block 7, and the rearmost transformer abuts against the contact block 5. The clamping spring 6 provides a forward contact tightening force for the transformer. After the transformer is placed in the placement groove 3, the upper layer board 1 can be turned backwards to be buckled with the lower layer board 2. At this time, each pressing block 9 applies a downward pressing force to the transformer, providing uniform and sufficient pressure for the transformer, so that the glue between each magnetic core and its corresponding PCB board fits better through the glue dropping, thereby improving the uniformity of the glue dropping.

[0028] Further, as Figure 5 shown, in order to achieve a better glue dropping and pressing effect, a pressing groove 10 is provided at the position corresponding to each pressing block 9 on the pressing rod 8. Each pressing block 9 is slidably connected to the corresponding pressing groove 10. A first spring 11 is provided between the upper side of each pressing block 9 and the corresponding pressing groove 10. A first boss is fixedly connected to the lower part of the pressing groove 10, and a second boss is fixedly connected to the upper side of the pressing block 9. When the pressing block 9 is not in contact with the workpiece, the pressing block 9 will not come out of the pressing groove 10 under the action of the first boss and the second boss;

[0029] When in use, when clamping the workpiece, each pressing block 9 is forced to move upwards to compress the first spring 11, and each pressing block 9 applies a continuous downward pressing force to the workpiece under the action of the first spring 11, thereby providing a continuous pressing force for the workpiece.

[0030] Further, as Figure 6 shown, in order to facilitate the installation of the workpiece, a first adjusting knob 12 is threadedly connected to the rear part of each adjusting rod 4. The middle part of each adjusting rod 4 is slidably connected to the lower layer board 2 through a sliding key, that is, the adjusting rod 4 will not rotate relative to the lower layer board 2;

[0031] When in use, the first adjusting knob 12 can be first rotated and tightened. The front side of the first adjusting knob 12 abuts against the rear side surface of the lower layer board 2, driving the adjusting rod 4 to move backwards. At this time, the adjusting rod 4 drives the contact block 5 to move backwards, and then the transformers can be placed in the placement groove 3 in sequence. After the placement is completed, the first adjusting knob 12 can be rotated in the reverse direction, and the clamping force is provided for the workpiece through the first spring 11 and the contact block 5.

[0032] Further, as Figures 1 - 4Given that, for the convenience of clamping and fixing the workpiece, two first square grooves 13 are provided at the rear of the lower layer plate 2, and second square grooves 14 are provided at the corresponding positions of the rear of the upper layer plate 1 for each of the first square grooves 13. A threaded rod 15 is rotatably connected inside each of the first square grooves 13, and a pressing knob 16 is threadedly connected to the middle of each threaded rod 15;

[0033] During use, when it is necessary to cooperate the upper layer plate 1 and the lower layer plate 2 to clamp the workpiece, after the upper layer plate 1 is rotated to the upper side of the lower layer plate 2, the threaded rod 15 in the second square groove 14 can be rotated upward so that the middle of the threaded rod 15 passes through the second square groove 14. At this time, the pressing knob 16 is located above the second square groove 14. Then, the pressing knob 16 is rotated so that the lower side surface of the pressing knob 16 contacts the upper side surface of the upper layer plate 1. At this time, the upper layer plate 1 and the lower layer plate 2 are relatively fixed, and the workpiece is clamped.

[0034] Furthermore, Figures 1 - 4 Given that, in order to accelerate the drying process after dispensing and reduce the weight of the device, a first ventilation groove 17 is provided on both the front and rear sides of the upper layer plate 1 corresponding to each pressing rod 8, and two second ventilation grooves 18 are provided at the bottom of each placement groove 3. During the dispensing process, dispensing operations can also be carried out through the first ventilation groove 17 and the second ventilation groove 18.

[0035] Furthermore, Figure 6 Given that, in order to enable the devices to be stacked, two support rods 19 are threadedly connected to the front part of the upper side of the upper layer plate 1, and a support knob 20 is threadedly connected to the rear part of the upper side of the upper layer plate 1. A support groove 21 adapted to the support rod 19 is provided on the lower side of the lower layer plate 2. Through the threaded connection design of the support rod 19 and the support knob 20, the height of the uppermost plane of the support rod 19 and the support knob 20 can be adjusted, so that multiple devices can be stacked;

[0036] During use, multiple devices can be stacked. At this time, the support groove 21 of the upper device cooperates with the support rod 19 of the lower device for support, and the support knob 20 of the lower device supports the rear part of the upper device.

[0037] Furthermore, Figures 1 - 4 Given that, in order to facilitate the cooperation with the dispensing machine, positioning holes 22 are provided on both the front and rear sides of the upper layer plate 1 and the lower layer plate 2.

[0038] When the utility model is in use, first, the upper layer plate 1 can be turned upwards and opened. Then, by rotating and tightening the first adjustment knob 12, the front side of the first adjustment knob 12 abuts against the rear side surface of the lower layer plate 2, driving the adjustment rod 4 to move backward. At this time, the adjustment rod 4 drives the contact block 5 to move backward. The transformers are arranged in the placement grooves 3 in sequence. Rotate the first adjustment knob 12 in the reverse direction. The contact block 5 is pushed by the clamping spring 6 to contact the side of the last transformer. At this time, the frontmost transformer abuts against the support block 7, and the rearmost transformer abuts against the contact block 5. The clamping spring 6 provides a forward contact tightening force for the transformer. After the transformer is placed in the placement groove 3, the upper layer plate 1 can be turned backward to be buckled with the lower layer plate 2. Rotate the threaded rod 15 in the second square groove 14 upwards so that the middle part of the threaded rod 15 passes through the second square groove 14. At this time, the pressing knob 16 is located above the second square groove 14. Then rotate the pressing knob 16 so that the lower side surface of the pressing knob 16 contacts the upper side surface of the upper layer plate 1. At this time, the upper layer plate 1 and the lower layer plate 2 are relatively fixed, clamping the workpiece. At this time, each pressing block 9 applies a downward pressing force to the transformer, providing uniform and sufficient pressure to the transformer, thereby improving the uniformity of dispensing. After that, multiple devices can be stacked. At this time, the support grooves 21 of the upper device and the support rods 19 of the lower device cooperate with each other for support, and the support knobs 20 of the lower device support the rear part of the upper device.

[0039] The utility model has a novel structure, ingenious concept, and simple and convenient operation. Through this design, the purpose of conveniently arranging and fixing the transformers uniformly is effectively achieved, realizing a better dispensing and pressing effect, facilitating the installation of transformer workpieces, conveniently clamping and fixing the workpieces, accelerating the drying process of the transformers after dispensing, reducing the overall weight of the device, increasing the function that the devices can be stacked, facilitating the cooperation with the dispenser, having simple operation, and also reducing the operation difficulty and error rate.

[0040] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. 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.
