Description

Technical Field

[0001] This utility model relates to the field of steel strip mounting technology, and in particular to an SMT steel strip mounting fixture. Background Technology

[0002] Steel strip is a widely used steel product in many fields, characterized by high precision, good surface quality, and ease of processing. Its main applications include manufacturing damping leaf springs and coil springs for automobiles, tractors, and locomotives; cylinder safety valve springs; and manufacturing medium and small cross-section leaf springs, such as front and rear auxiliary leaf springs for automobiles.

[0003] However, in the existing technology, the installation of steel strips for circuit boards is often done manually. Manual installation is prone to deviations, which affects the final installation quality of the product and cannot guarantee the uniform production standards of the product. To address this, we propose an SMT steel strip mounting fixture. Utility Model Content

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting a fixing strip and an extrusion plate, the circuit board can be placed between the fixing strip and the extrusion plate. The extrusion plate is pushed by a spring to ensure that the extrusion plate and the fixing strip stably clamp and fix the circuit board, providing a stable installation environment for the installation of steel sheet materials, and also making the placement and fixing of the circuit board more convenient.

It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model discloses an SMT steel strip mounting fixture, including a base plate 1. An auxiliary fixing mechanism is provided on the upper surface of the base plate 1. A support plate 2 is vertically fixedly mounted on the upper surface of the base plate 1. An H-shaped mounting bracket 3 is fixedly mounted on the upper part of the support plate 2. An adsorption plate 4 is mounted on the mounting bracket 3 via a lifting control mechanism. The adsorption plate 4 slides in cooperation with the mounting bracket 3 and the support plate 2. Multiple air pressure grooves 5 are vertically fixedly inserted through the lower surface of the adsorption plate 4. Soft washers are fixedly installed on the lower wall of each air pressure groove 5. The soft washers improve the fit between the device and the steel strip, ensuring the air pressure grooves... The device achieves a good sealing effect. A connecting plate 6 is horizontally placed on the adsorption plate 4. The connecting plate 6 is connected to a movable adjustment mechanism. A transfer rod 7 that moves through the air pressure tank 5 is vertically fixed on the lower end face of the connecting plate 6. A piston 8 that slides on the inner wall of the air pressure tank 5 is fixedly installed at the end of the transfer rod 7. The device quickly fixes the circuit board by using the pressing plate 11 pressed by the spring 14 and the fixing bar 9. It also uses the pressure difference between the inside and outside to adsorb and fix the steel sheet. Then, the first electric push rod 15 is controlled to drive the adsorption plate 4 to move, so as to achieve the joint fixation of the steel sheet and the circuit board.

[0024] Specifically, the auxiliary fixing mechanism includes a fixing strip 9 horizontally fixedly installed on the upper surface of the base plate 1. The fixing strip 9 is L-shaped and can limit the circuit board to ensure stable connection between the circuit board and the steel sheet. An installation block 10 is fixedly installed on the upper surface of the base plate 1 away from the fixing strip 9. An extrusion plate 11 is horizontally arranged between the installation block 10 and the fixing strip 9. Two pull rods 12 that movably pass through the installation block 10 are horizontally fixedly installed on the outer wall of the extrusion plate 11. The two pull rods 12 are fixedly connected by a synchronizing rod 13. The extrusion plate 11 is fixedly connected to the installation block 10 by a spring 14 that is movably sleeved on the outer wall of the pull rod 12. Pulling the synchronizing rod 13 can indirectly drive the extrusion plate 11 to move outward against the force of the spring 14, increasing the distance between the fixing strip 9 and the extrusion plate 11. The circuit board can be placed between the fixing strip 9 and the extrusion plate 11 for stable fixing.

[0025] More specifically, the lifting control mechanism includes a first electric push rod 15 vertically fixedly installed on the upper part of the mounting frame 3. The free end of the first electric push rod 15 moves through the mounting frame 3 and the connecting plate 6. The free end of the first electric push rod 15 is fixedly connected to the adsorption plate 4. The first electric push rod 15 can drive the adsorption plate 4 to move up and down, so that the steel sheet on the lower surface of the adsorption plate 4 can be combined with the circuit board to realize the installation and docking of the steel sheet.

[0026] Furthermore, the movable adjustment mechanism includes a second electric push rod 16 that is vertically fixedly installed on the upper surface of the adsorption plate 4. The free end of the second electric push rod 16 is fixedly connected to the lower surface of the connecting plate 6. The second electric push rod 16 can indirectly drive the piston 8 to move up and down, change the air pressure in the air pressure groove 5 during sealing, and fix the steel sheet material by using the pressure difference between the inside and outside.

[0027] Working principle:

[0028] Pull the synchronizing rod 13 outward. The synchronizing rod 13, through the transmission of the pulling rod 12, pulls the extrusion plate 11, causing the extrusion plate 11 to overcome the force of the spring 14 and move away from the fixing strip 9. Then, place the circuit board between the fixing strip 9 and the extrusion plate 11, so that the circuit board and the fixing strip 9 come into contact. Then, cancel the operation of the synchronizing rod 13, causing the spring 14 to push the extrusion plate 11 back to its original position, pressing and fixing the circuit board. Then, attach the steel sheet to the lower surface of the adsorption plate 4. The second electric push rod 16 extends, causing the connecting plate 6 to move upward. The connecting plate 6, through the adapter rod 7, causes the piston 8 to move upward. The space inside the air pressure tank 5 increases, and the air pressure decreases. The pressure difference between the inside and outside of the air pressure presses and fixes the steel sheet. Then, the first electric push rod 15 extends, causing the adsorption plate 4 to move downward, so that the steel sheet on the lower surface of the adsorption plate 4 is installed and connected with the circuit board. Then, control the second electric push rod 16 to return to its original position, so that the air pressure inside the air pressure tank 5 returns to its normal value, and the steel sheet is put down. Then, control the first electric push rod 15 to return to its original position, completing the installation.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
