Description

Technical Field

[0001] This utility model relates to the technical field of switch bare circuit board equipment, specifically a switch bare circuit board positioning device. Background Technology

[0002] A bare switch circuit board is a basic form of circuit board, containing only basic printed circuitry without subsequent processing and assembly steps. This type of circuit board is typically a core component of electronic devices such as switching power supplies, used to connect and support various electronic components. In current technology, other components need to be mounted on the bare switch circuit board, requiring it to be secured. Instead of using magnetic attachment, the assembly process relies on traditional fixing methods such as screws and clips. These methods usually require more time and tools, and cause greater wear and tear on the surface of the bare switch circuit board.

[0003] For example, the authorized patent document with application number CN202322823457.X discloses a switching power supply circuit board, including a main body and a linear voltage regulator. The linear voltage regulator includes a Zener diode, a voltage regulator, and a linear amplifier. This utility model provides a switching power supply circuit board where the Zener diode achieves voltage regulation when its forward voltage is less than a specific voltage. The voltage regulator is used to adjust the range of the output voltage. The negative feedback circuit of the linear amplifier adjusts the output voltage to maintain its stability. The feedback circuit detects the output voltage and current. The rectifier bridge converts the positive and negative half-cycles of the power supply output into unidirectional current signals. The filter capacitor is used to filter out high-frequency noise signals in the DC power supply. The switching transistor is used to control the switching of the circuit to achieve high-efficiency power conversion. The output circuit further filters and adjusts the output voltage. The drive circuit is used to control the switching transistor to ensure circuit stability. The isolation transformer reduces electromagnetic interference and enhances safety.

[0004] The aforementioned patents require fixing the circuit board, but do not use an adsorption-type fixing method. During the assembly process, the bare switch circuit board relies on traditional fixing methods such as screws and clips, which causes significant wear on the surface of the bare switch circuit board. Therefore, we need to provide a positioning device for the bare switch circuit board. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for a bare circuit board of a switch, comprising:

[0026] Operating frame 1;

[0027] The operating table 2 is set inside the operating frame 1. The operating table 2 is equipped with an adsorption fixing mechanism 3 for fixing the bare circuit board of the switch and avoiding scratching the surface of the circuit board.

[0028] The operating frame 1 is equipped with a multi-directional sliding mechanism 4 for moving and adjusting the operating table 2;

[0029] Specifically, an adsorption fixing mechanism 3 for positioning and installing the bare circuit board of the switch is set on the surface of the operating table 2. Adsorption fixing can avoid damage to the circuit board and components due to improper operation or improper fixing method. Adsorption fixing is gentler and can better protect the circuit board and components.

[0030] The adsorption and fixing mechanism 3 includes several sleeves 31 embedded in the operating table 2. Each sleeve 31 is provided with a piston 30. Each piston 30 has a push rod 32 fixedly installed at the bottom. Each push rod 32 has a push plate 33 fixedly installed at the bottom. The bottom of the operating table 2 is embedded with two first cylinders 34. The lower ends of the two first cylinders 34 are fixedly installed on the top of the push plate 33.

[0031] In this embodiment, the bare circuit board of the switch needs to be fixed on the operating table 2, above several adhesive rings 6. First, two second cylinders 73 are activated, pushing the pressure rod 72. The pressure rod 72 is hinged to the mounting plate 71, causing one end of the pressure rod 72 to press down. The adhesive ball 8 at one end of the pressure rod 72 presses the circuit board firmly onto the adhesive rings 6, making the bottom of the circuit board better fit the adhesive rings 6. At this time, two first cylinders 34 are activated. The two first cylinders 34 are synchronous cylinders, driving the push plate 33 to move down. The push plate 33 drives several push rods 32 to move down. The piston 30 moves downward inside the sleeve 31. Due to the seal between the bottom of the circuit board and the adhesive ring 6, the air pressure inside the sleeve 31 and at the top of the piston 30 decreases, thereby generating an adsorption force to adsorb and position the circuit board. The motor 44 can be started to drive the threaded rod 43 to rotate. The surface of the threaded rod 43 is threaded with the sliding seat 45, which drives the sliding seat 45 and the operating table 2 to move. In addition, two electric push rods 11 are synchronous push rods, which drive the movement and adjustment of the support frame 42, so that the circuit board can slide and adjust in multiple directions within the operating frame 1.

[0032] The piston 30 includes a movable seat 301 fixedly mounted on the top of the push rod 32. The surface of the movable seat 301 is provided with an annular groove 302. A sealing ring 303 is engaged inside the annular groove 302. The surface of the sealing ring 303 is tightly fitted with the inner wall of the sleeve 31. The sealing ring 303 is a rubber ring.

[0033] Specifically, the movable seat 301 moves inside the sleeve 31 under the drive of the push rod 32, and a sealing ring 303 is provided in the annular groove 302 on the surface of the movable seat 301. The surface of the sealing ring 303 is tightly attached to the inner wall of the sleeve 31, thereby reducing the air pressure inside the sleeve 31 and at the top of the piston 30, thereby generating an adsorption force to adsorb and position the circuit board.

[0034] Several sleeves 31 have discharge grooves 5 on both sides, and the discharge grooves 5 are connected to the inside of the sleeves 31. Several sleeves 31 are fixedly installed with adhesive rings 6 on the top.

[0035] Furthermore, the discharge groove 5 is connected to the sleeve 31, which allows the piston 30 to be moved below the discharge groove 5. Debris inside the sleeve 31 can be discharged through the discharge groove 5, facilitating the cleaning of the sleeve 31.

[0036] It also includes a pressing assembly 7 for assisting in pressing the circuit board. The pressing assembly 7 includes mounting plates 71 fixedly installed on both sides of the operating table 2. The top of each of the two mounting plates 71 is hinged with a pressure rod 72. The opposite ends of the two pressure rods 72 are hinged with a second cylinder 73. The lower end of the second cylinder 73 is hinged to one side of the mounting plate 71.

[0037] It is worth noting that the bare circuit board of the switch needs to be fixed on the operating table 2 and placed above several adhesive rings 6. First, the two second cylinders 73 are activated. The second cylinders 73 push the pressure rod 72, which is hinged to the mounting plate 71. This causes one end of the pressure rod 72 to press down, and the adhesive ball 8 at one end of the pressure rod 72 presses the circuit board tightly onto the adhesive rings 6, so that the bottom of the circuit board fits better against the adhesive rings 6, and the bottom of the circuit board is sealed to the adhesive rings 6.

[0038] Each of the two pressure rods 72 has a rubber ball 8 at one of its adjacent ends, and the top of the operating table 2 is provided with an alignment groove group 9;

[0039] Among them, the adhesive ball 8 at one end of the pressure rod 72 presses the circuit board tightly onto several adhesive rings 6. The adhesive ball 8 deforms when it adheres to the circuit board, which reduces scratches on the surface of the circuit board and enhances the friction. In addition, the alignment slot group 9 is set on the top of the operating table 2 to facilitate the positioning and placement of the circuit board.

[0040] The multi-directional sliding mechanism 4 includes two slide grooves 41 opened on the inner wall of the operating frame 1. A support frame 42 is slidably installed inside the two slide grooves 41. A threaded rod 43 is rotatably installed inside the support frame 42. A motor 44 is installed at one end of the threaded rod 43, and a sliding seat 45 is threadedly installed on the surface of the threaded rod 43. The top of the sliding seat 45 is fixedly installed to the bottom of the operating table 2.

[0041] It is worth noting that the startable motor 44 drives the threaded rod 43 to rotate, and the surface of the threaded rod 43 is threaded with the inner thread of the sliding seat 45, which drives the sliding seat 45 and the operating table 2 to move. In conjunction with two electric push rods 11, which are synchronous push rods 32, the support frame 42 is moved and adjusted, so that the circuit board can slide and adjust in multiple directions within the operating frame 1.

[0042] The operating frame 1 has two electric push rods 11 embedded inside. The two electric push rods 11 are respectively set in two slide grooves 41. The bottom of the sliding seat 45 is fixedly installed with a guide seat 10. The inside of the guide seat 10 is slidably installed with the surface of the support frame 42.

[0043] A guide seat 10 is provided at the bottom of the sliding seat 45. The guide seat 10 is slidably mounted on the surface of the support frame 42 and provides guidance and conveying for the sliding seat 45.

[0044] This device requires the bare circuit board of the switch to be placed on the operating table 2, above several adhesive rings 6. First, two second cylinders 73 are activated, pushing the pressure rod 72, which is hinged to the mounting plate 71. This causes one end of the pressure rod 72 to press down, and the adhesive ball 8 at one end of the pressure rod 72 presses the circuit board firmly onto the adhesive rings 6, making the bottom of the circuit board better fit the adhesive rings 6. At this time, two first cylinders 34 are activated. The two first cylinders 34 are synchronous cylinders, driving the push plate 33 to move down. The push plate 33 drives several push rods 32 to move down, thus... As the plug 30 moves downward within the sleeve 31, the air pressure inside the sleeve 31 and at the top of the piston 30 decreases due to the seal between the bottom of the circuit board and the adhesive ring 6, generating an adsorption force that positions the circuit board. This allows the motor 44 to rotate the threaded rod 43, which is threaded onto the sliding seat 45, causing the sliding seat 45 and the operating table 2 to move. In conjunction with two electric push rods 11, which are synchronous push rods, the support frame 42 is moved and adjusted, allowing the circuit board to slide and adjust in multiple directions within the operating frame 1.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
