DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Please refer to Figure 1-7 As shown, the present invention is an assembly welding pressing jig for a 5G communication module and a method for using the same, comprising a jig base 1, a jig cover 2 and a transmission assembly, a limit block 15 is installed on the side wall of the jig cover 2, the limit block 15 slides back and forth on the side wall of the jig cover 2 through the transmission assembly, and a slide groove for the reciprocating sliding of the limit block 15 is provided on the side wall of the jig cover 2, and the clamping and locking of the CPU housing is achieved through the reciprocating sliding of the limit block 15.

[0031] The upper end of the jig base 1 is evenly provided with limiting grooves 4 for placing the PCB board, and there can be multiple limiting grooves 4. The inside of the jig pressure cover 2 is provided with installation grooves 3 for limiting the CPU housing, and there can be multiple installation grooves 3. The number of limiting grooves 4 and the number of installation grooves 3 are equal and their positions are vertically opposite to each other. The setting of the limiting grooves 4 and the installation grooves 3 can achieve the correct position of the PCB board and the CPU housing before assembly.

[0032] The transmission assembly includes a sliding block 16, the outer wall of which is fixedly connected to a connecting rod, and the other end of the connecting rod away from the sliding block 16 is fixedly connected to the limit block 15. The sliding block 16 and the limit block 15 can move synchronously through the connecting rod, so that the limit block 15 can be driven to slide when the sliding block 16 slides.

[0033] The sliding block 16 is reset by a reset assembly, and the sliding block 16 is made to slide back and forth by the reset assembly.

[0034] The upper end of the jig base 1 is fixedly connected with a locking block 18 that cooperates with the sliding block 16. When the jig cover 2 is pressed, the sliding block 16 generates a downward force. The sliding block 16 cooperates with the locking block 18 to slide in a direction away from the limit block 15, driving the limit block 15 to slide synchronously.

[0035] The reset assembly includes a third elastic member 17, both ends of which are fixedly connected to the outer wall of the sliding block 16 and the inner wall of the sliding groove respectively. When the sliding block 16 and the locking block 18 cooperate with each other to slide, the third elastic member 17 is squeezed, which has a tendency to reset the sliding block 16 in real time. When the fixture cover 2 is lifted upward, the locking block 18 cancels the restriction on the sliding block 16, and the sliding block 16 is reset by the action of the third elastic member 17.

[0036] The side wall of the mounting groove 3 is fixedly connected with a snap-fit ​​block 13, the radial outer wall of the snap-fit ​​block 13 is bent, a plurality of snap-fit ​​blocks 13 are provided, and at least two snap-fit ​​blocks 13 are symmetrically arranged on the inner wall of the mounting groove 3. Before the PCB board and the CPU housing are assembled, the CPU housing is placed into the mounting groove 3, and the CPU housing is pressed so that the CPU housing passes through the snap-fit ​​block 13 and is stationary between the snap-fit ​​block 13 and the limit block 15, resulting in an interference fit phenomenon, which is convenient for the subsequent assembly process.

[0037] The outer wall of the jig cover 2 is fixedly connected with a positioning column 11, and the outer wall of the jig base 1 is provided with a positioning hole 12 for the positioning column 11 to be inserted. When assembling the CPU housing and the PCB board, the positioning column 11 is inserted into the corresponding positioning hole 12 to achieve the positioning of the jig base 1 and the jig cover 2, so that the positions of the CPU housing and the PCB board correspond to each other, and it is not easy to cause the assembly position deviation.

[0038] The inner wall of the positioning hole 12 is provided with a first elastic member 5 for resetting the positioning column 11. One end of the first elastic member 5 away from the jig cover 2 is fixedly connected to the inner wall of the positioning hole 12. When the jig base 1 and the jig cover 2 are assembled, the positioning column 11 is inserted into the positioning hole 12, and the first elastic member 5 is squeezed, which has a tendency to reset the positioning column 11 in real time. At the same time, the first elastic member 5 cannot release potential energy by restricting the jig base 1 through the mounting strip 9.

[0039] After the assembly process is completed, the installation block 10 is pressed to cancel the restriction of the installation bar 9 on the jig base 1, so that the first elastic member 5 releases the potential energy, and the positioning column 11 is subjected to a force away from the jig base 1, thereby causing the jig cover 2 to slide upward, and the installation bar 9 slides upward at the same time, so that after the assembly process is completed, the installation block 10 can be pressed to move the jig cover 2 upward and separate the jig cover 2 from the jig base 1. There is no need to pick up the jig cover 2 while pressing the installation block 10, which frees one hand of the staff member and allows single-handed operation, thereby improving work efficiency.

[0040] The side wall of the jig base 1 is slidably connected with a mounting block 10, and a plurality of mounting blocks 10 are provided, and every two mounting blocks 10 are arranged opposite to each other on the side wall of the jig base 1. An directional groove for sliding the mounting block 10 is provided inside the jig base 1, and the inner wall of the directional groove is provided with a second elastic member 6 for resetting the mounting block 10. The two ends of the second elastic member 6 are respectively fixedly connected to the inner wall of the jig base 1 and the outer wall of the mounting block 10. The side of the mounting strip 9 away from the mounting block 10 is a wedge-shaped structure, and the side wall of the jig gland 2 is fixedly connected with a mounting strip 9 matching the mounting block 10. When the jig base 1 and the jig gland 2 are assembled, the mounting strip 9 generates a force on the mounting block 10 through the sloped inclined surface, so that the mounting block 10 slides in the direction close to the jig base 1. At this time, the second elastic member 6 is fixedly connected to the inner wall of the jig base 1 and the outer wall of the mounting block 10. The second elastic member 6 is squeezed, which has a tendency to reset the mounting block 10 in real time. When the mounting strip 9 passes through the horizontal position of the mounting block 10, the mounting strip 9 cancels the restriction on the mounting block 10, and the mounting block 10 is reset by the second elastic member 6, so that the mounting strip 9 is engaged with the mounting block 10. At the same time, when the jig base 1 and the jig pressure cover 2 are in contact directly opposite each other, the side of the mounting strip 9 away from the jig base 1 is in contact with the side of the mounting block 10 away from the jig pressure cover 2, so that after the jig base 1 and the jig pressure cover 2 are assembled, it is not easy to loosen and cause the jig pressure cover 2 to deviate from the predetermined position. At the same time, after the assembly process is completed, the mounting block 10 is pressed to cancel the restriction of the mounting block 10 on the mounting strip 9, so that the jig pressure cover 2 can be removed while pressing the mounting block 10.

[0041] The lower end of the jig cover 2 is fixedly connected with a guide block 7, and the guide block 7 is wedge-shaped at one end away from the jig cover 2. The upper end of the jig base 1 is provided with a guide groove 8 for cooperating with the guide block 7. When the jig cover 2 is pressed into the jig base 1 and there is a position deviation, the guide block 7 will slide toward the predetermined position in accordance with the inner wall of the guide groove 8 through the downward force generated when the jig cover 2 is pressed, so that the jig cover 2 slides to the predetermined position, and at the same time, the positioning column 11 is inserted into the positioning hole 12, so that when the jig cover 2 is pressed into the jig base 1 and there is a position deviation, the jig cover 2 can slide to the predetermined position through the mutual cooperation of the guide block 7 and the guide groove 8.

[0042] The side wall of the limiting groove 4 is provided with a groove 14 for convenient fingers to take the PCB board. The inner wall of the groove 14 is bent. After the assembly process is completed, the finger is inserted into the groove 14 and the finished product can be taken out by pinching, thereby realizing the taking of the finished product after the assembly process and reducing the probability of damage to the finished CPU caused by the deviation of the finger insertion direction when taking it.

[0043] The first elastic member 5 , the second elastic member 6 and the third elastic member 17 may be springs commonly used in the prior art. The symmetrically arranged springs may facilitate the resetting of the positioning column 11 , the mounting block 10 and the sliding block 16 .

[0044] Working principle of the present invention:

[0045] Please refer to Figure 1-7 As shown, when the CPU housing and the PCB board need to be assembled and welded, first install the PCB board in the limiting groove 4, install the CPU housing in the installation groove 3, press the CPU housing so that the CPU housing is engaged between the engaging block 13 and the limiting block 15, press the jig cover 2 toward the jig base 1, so that the jig cover 2 fits with the jig base 1, and when the jig cover 2 is pressed into the jig base 1 and there is a positional offset, the jig cover 2 slides to a predetermined position through the cooperation between the guide block 7 and the guide groove 8, so that the positioning column 11 is inserted into the positioning hole 12, the first elastic member 5 is squeezed, so that the positioning column 11 has a tendency to reset in real time, the locking block 18 squeezes the sliding block 16 to make the sliding block 16 slide, and the third elastic member 17 is squeezed, so that the sliding block 16 has a tendency to reset in real time, thereby driving the limiting block 15 to slide synchronously, thereby reducing the clamping force on the CPU housing.

[0046] Then, the CPU housing is pressed to make it fall and contact with the PCB board. At this time, the top surface of the CPU housing is still restricted by the limit block 15. The limit block 15 can limit the relative position between the CPU housing and the PCB board to achieve interference fit between the CPU housing and the limit block 15. At the same time, through the fit between the jig cover 2 and the jig base 1, the mounting bar 9 generates a force on the mounting block 10 through the sloped inclined surface, so that the mounting block 10 slides in the direction close to the jig base 1. At this time, the second elastic member 6 is squeezed, which has a tendency to reset the mounting block 10 in real time.

[0047] When the jig cover 2 is matched with the jig base 1, the mounting bar 9 passes through the horizontal position of the mounting block 10, the mounting bar 9 cancels the restriction on the mounting block 10, and the mounting block 10 is reset by the second elastic member 6, so that the mounting bar 9 is engaged with the mounting block 10, so that after the jig base 1 and the jig cover 2 are assembled, they are not easy to loosen, and the assembly process can be completed.

[0048] After the assembly process is completed, the installation block 10 is pressed to cancel the restriction of the installation bar 9 on the jig base 1, so that the first elastic member 5 releases the potential energy, and the positioning column 11 is subjected to a force away from the jig base 1, thereby causing the jig cover 2 to slide upward. After the assembly process is completed, the installation block 10 can be pressed to move the jig cover 2 upward and separate the jig cover 2 from the jig base 1. There is no need to take the jig cover 2 while pressing the installation block 10, which frees up one hand of the staff member and allows single-handed operation, thereby improving work efficiency.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
