Description

Technical Field

[0001] This utility model relates to the field of control board assembly technology, specifically to a snap-fit ​​quick positioning tooling structure for control board assembly. Background Technology

[0002] The control board is an indispensable core component in modern electronic devices. It integrates various electronic components and circuits to realize the control and management functions of the equipment. The assembly process of the control board refers to combining the control board material with various electrical components through certain processes and methods to form a complete control board structure. In the assembly process, positioning is crucial, because only by accurately and firmly fixing the control board material can subsequent welding, connection and other operations be kept stable, thereby ensuring the performance and reliability of the control board.

[0003] However, in the existing control board assembly process, the positioning work faces many problems. Traditional positioning methods usually rely on simple mechanical clamps. Although these clamps can provide a certain fixing effect, they can usually only provide force on both sides of the board, which may not provide sufficient stability. This can easily cause the board to deviate during the assembly process, thus affecting the assembly quality, leading to unstable product quality and increased production costs. Therefore, based on the above problems, a snap-fit ​​quick positioning tooling structure for control board assembly is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a snap-fit ​​quick positioning fixture structure for assembling control boards, in order to solve the problem that existing control boards are mostly fixed using simple mechanical clamps. Although these clamps can provide a certain degree of fixation, they usually only apply force to the two sides of the board and may not provide sufficient stability. This can easily cause the board to tilt during assembly, thus affecting the assembly quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A snap-fit ​​quick-positioning fixture structure for assembling control boards includes a base. The inner side of the base has several equidistantly arranged positioning holes. A magnetic block is fixedly connected to the lower inner wall of each positioning hole. Several locking and positioning modules are installed on the base. Each locking and positioning module includes a guide pin inserted into the positioning hole. A bearing portion is installed at the upper end of the guide pin. The bearing portion includes a lower cavity seat fixedly connected to the guide pin. A support plate is fixedly connected to the upper side of the lower cavity seat. A positioning post is fixedly connected to the upper side of the support plate. The positioning post and the lower cavity seat... The inner side of the support plate has a cavity that passes through it. The upper side of the cavity has a rail groove. A locking part is installed at the bearing part. The locking part includes a rail seat fixed to the inner side of the cavity. A pair of rail blocks are slidably connected to the inner side of the rail seat. Each rail block has a locking block that is slidably connected to the rail groove on its upper side. A spring is fixedly connected between a group of locking blocks. A bracket located on the upper side of the seat body is fixedly connected to the outer side of the guide pin. Each end of the bracket away from the guide pin has a receiving hole. A positioning rod for inserting into the positioning hole is fixedly connected to the inner side of each receiving hole.

[0006] Preferably, the card block has an L-shaped structure, with the upper corner blocks of the card block all located on the upper side of the positioning post, and the inclined surface of the upper corner blocks of the card block is set as an inclined curved surface.

[0007] Preferably, the inner side of the rail seat has a through hole arranged longitudinally, the left side of the lower cavity seat has a retaining rail, and pull ropes are fixedly connected to the opposing surfaces of a pair of rail blocks. The other end of each pull rope passes through the through hole and is fixedly connected to a pull plate. A control rod located in the retaining rail is fixedly connected to the left side of the pull plate.

[0008] Preferably, the pull plate is located inside the cavity, the diameter of the pull plate is the same as the inner diameter of the cavity, the outer curved surface of the pull plate fits into the inner curved surface of the cavity, and the inner diameter of the perforation is four times the diameter of the pull rope.

[0009] Preferably, the control rod consists of a connecting rod and a pinch head, the rail is an L-shaped rail structure, the rail width is the same as the diameter of the connecting rod of the control rod, and the connecting rods of the control rod are all slidably connected to the rail.

[0010] Preferably, the positioning rod is composed of a metal rod and a damping sleeve. The metal rod of the positioning rod has a longitudinally penetrating air passage on its inner side. The diameter of the damping sleeve of the positioning rod is the same as the inner diameter of the positioning hole. The outer curved surface of the damping sleeve of the positioning rod fits against the inner wall of the positioning hole.

[0011] Preferably, the lower ends of the metal rods of the positioning rods are in contact with the upper end face of the magnetic block, the lower end face of the metal rods of the positioning rods is on the same plane as the lowest point of the guide pin, and the diameter of the guide pin is the same as the inner diameter of the positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the structure including a base, positioning holes, magnetic blocks, and locking modules allows the base to securely position the locking modules in conjunction with the positioning holes and magnetic blocks. Each locking module, in conjunction with the fixing holes of the control board, enables multi-directional positioning of the control board. This positioning method facilitates rapid positioning of other control boards in the same batch, realizing a snap-fit ​​quick-positioning fixture structure that can quickly position the control board from multiple directions. This ensures the stability of the control board during assembly, solving the problem that existing methods of fixing control boards often use simple mechanical clamps, which, while providing some fixation, typically only apply force to the sides of the board and may not provide sufficient stability, easily causing the board to tilt during assembly and affecting assembly quality.

[0021] Please see Figure 1-6 This utility model provides a technical solution: A snap-fit ​​quick-positioning fixture structure for assembling control boards includes a base 1. The inner side of the base 1 has several equidistantly arranged positioning holes 2. Magnetic blocks 3 are fixedly connected to the lower inner walls of each positioning hole 2. Several locking and positioning modules 4 are installed on the base 1. Each locking and positioning module 4 includes a guide pin 41 inserted into the positioning hole 2. A bearing part 42 is installed at the upper end of the guide pin 41. The bearing part 42 includes a lower cavity seat 421 fixedly connected to the guide pin 41. A support plate 422 is fixedly connected to the upper side of the lower cavity seat 421. A positioning post 423 is fixedly connected to the upper side of the support plate 422. A through-bracing support plate 423 is provided between the positioning post 423 and the inner side of the lower cavity seat 421. The cavity 424 of 22 has a rail groove 426 on its upper side. A locking part 43 is installed at the bearing part 42. The locking part 43 includes a rail seat 431 fixed inside the cavity 424. A pair of rail blocks 432 are slidably connected to the inner side of the rail seat 431. Each rail block 432 has a locking block 433 fixedly connected to its upper side, which is slidably connected to the rail groove 426. A spring 434 is fixedly connected between a set of locking blocks 433. A bracket 44 located on the upper side of the seat 1 is fixedly connected to the outer side of the guide pin 41. Each end of the bracket 44 away from the guide pin 41 has a receiving hole 45. A positioning rod 46 for inserting into the positioning hole 2 is fixedly connected to the inner side of each receiving hole 45.

[0022] The locking block 433 has an L-shaped structure. The upper corner blocks of the locking block 433 are all located on the upper side of the positioning post 423. The inclined surfaces of the upper corner blocks of the locking block 433 are curved surfaces. This design allows the pair of locking blocks 433 to automatically move towards each other when pressed from top to bottom. The inner side of the rail base 431 has a longitudinally penetrating through hole 435. The left side of the lower cavity base 421 has a locking rail 425. A pull rope 436 is fixedly connected to the facing surfaces of the pair of rail blocks 432. The other end of each pull rope 436 passes through the through hole 435 and is fixedly connected to a pull plate 437. A control rod 438 located inside the locking rail 425 is fixedly connected to the left side of the pull plate 437. This design allows... The operator can manually control the opposing displacement of a pair of locking blocks 433 and lock them in place so that the operator can remove the control plate. The pull plate 437 is located inside the cavity 424, and its diameter is the same as the inner diameter of the cavity 424. The outer curved surface of the pull plate 437 fits against the inner curved surface of the cavity 424. This design ensures the pull plate 437 remains stable during displacement and rotation. The inner diameter of the perforation 435 is four times the diameter of the pull rope 436, ensuring that the upward movement of the pull plate 437 is not affected by air pressure. The control rod 438 consists of a connecting rod and a pinch head. The locking rail 425 has an L-shaped track structure. The rail width of 425 is the same as the diameter of the connecting rod of control rod 438. The connecting rods of control rod 438 are slidably connected to the rail 425. This configuration ensures the stability of control rod 438 during displacement, allowing it to maintain its position when moving into the transverse groove of rail 425. Positioning rod 46 consists of a metal rod and a damping sleeve. A longitudinally penetrating air passage is provided on the inner side of the metal rod of positioning rod 46. This design prevents the downward movement of positioning rod 46 from being affected by air pressure. The diameter of the damping sleeve of positioning rod 46 is the same as the inner diameter of positioning insertion hole 2. The outer curved surface of the damping sleeve fits against the inner wall of the positioning hole 2. This setting allows the damping between the positioning rod 46 and the positioning hole 2 to position the entire locking module 4. The lower end of the metal rod of the positioning rod 46 fits against the upper end face of the magnetic block 3. This setting further positions the positioning rod 46. The lower end face of the metal rod of the positioning rod 46 is on the same plane as the lowest point of the guide pin 41. The diameter of the guide pin 41 is the same as the inner diameter of the positioning hole 2. This setting allows the guide pin 41 to guide the surrounding positioning rods 46, making it easier for each of the surrounding positioning rods 46 to be inserted into the positioning hole 2.

[0023] Workflow: During control board assembly, the positioning process of the snap-fit ​​quick-positioning fixture structure is as follows: First, based on the number of pre-drilled fixing holes for the next batch of control boards to be assembled, select the corresponding number of snap-fit ​​positioning modules 4. Take out one control board from that batch and insert the upper ends of each snap-fit ​​positioning module 4 into the fixing holes of the control board. During insertion, the fixing holes of the control board apply pressure to the upper corner blocks of the snap-fit ​​blocks 433, causing a pair of snap-fit ​​blocks 433 to move towards each other and compress the spring 434, thus allowing the fixing holes to pass smoothly through the pair of snap-fit ​​blocks 433 and be fitted onto the outside of the positioning post 423. After the fixing holes pass through the snap-fit ​​blocks 433, the snap-fit ​​blocks 433 will unfold and reset under the elastic force of the spring 434. At this time, the control board... The lower end face of the plate is tightly fitted with the upper end face of the support plate 422, while the upper end face of the plate is fitted with the lower end face of the locking block 433, thus being firmly locked in place by a pair of locking blocks 433. Through the above operation, each locking module 4 can be installed in the corresponding fixing hole of the control plate, completing the preparation work; then, each locking module 4 is inserted into the corresponding positioning hole 2. The insertion of the guide pin 41 will guide the surrounding positioning rods 46, making it easier for the surrounding positioning rods 46 to be inserted into the positioning hole 2. Through the damping applied by each positioning rod 46 to the inserted positioning hole 2, combined with the magnetic attraction of the magnetic block 3 on the positioning rods 46, each locking module 4 can be securely fixed on the base 1, thereby realizing With the precise positioning of the locking module 4 and its control board, the control board can then be assembled using external assembly equipment. Once the previous control board is assembled, if it's necessary to replace it with the next control board from the same batch, the operator can move the control levers 438 of each locking module 4, causing them to move downwards into the transverse grooves of the rails 425. This, in turn, moves the pull plate 437 downwards and positions it. The downward movement of the pull plate 437 pulls a pair of rail blocks 432 and locking blocks 433 in opposite directions via the pull rope 436, thus releasing the locking of the control board material. This allows the operator to directly move upwards and remove the control board. Subsequently, the next control board to be assembled can be removed. Since both belong to the same batch, the fixing holes of the control board to be assembled can directly align with each locking module. Align the positioning pins 423 of the locking module 4, and simply install it back to its original position. After installation, reset the control rod 438 to move the pull plate 437 and pull rope 436 upwards. The locking block 433 resets under the action of the spring 434, positioning the newly installed control board. Through the above operations, the snap-fit ​​quick positioning fixture structure can quickly position the control board from multiple directions to ensure that the control board remains stable during assembly. This solves the problem that existing control board fixing methods mostly use simple mechanical clamps, which, although they can provide a certain fixing effect, usually only provide force on both sides of the board and may not provide sufficient stability. This can easily cause the board to tilt during assembly, thus affecting the assembly quality.

[0024] 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.
