Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic product repair, and particularly relates to a board disassembling tool for a protective housing. Background Art
[0002] The whole process of a PCB blank board through SMT component mounting or DIP plug-in is called PCBA, and the finished product is called a PCBA circuit board with pins at the edge. The PCBA circuit board is usually encapsulated in a module housing by potting to form a PCBA circuit module, and the pins extend outside the module housing after encapsulation. When the PCBA circuit module needs to be repaired, the module housing and the PCBA circuit board need to be peeled off, and the peeled module housing needs to be reused as much as possible to reduce costs. At present, when repairing the PCBA circuit module, manual disassembly is usually adopted, that is, using a bench vise to clamp the module housing, and at the same time using a pair of needle-nose pliers to clamp the pins of the PCBA circuit board and drag. In this way, since the force applied by the bench vise to the module housing has a component force perpendicular to the dragging direction, it is easy to damage the module housing, resulting in the module housing being unable to be reused again. Moreover, the method of clamping the module housing with the bench vise and dragging the pins with the needle-nose pliers will be affected by factors such as different operators or the force application angle, resulting in uneven force, which is easy to cause the PCBA circuit board to tear and reduce the repair efficiency.
[0003] How to solve the above technical problems is the subject faced by the utility model. Summary of the Utility Model

Specific embodiments
[0025] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.
[0026] A board - removing tooling for a protective housing includes a bottom block 1, a wire - pressing block 2, and a board - removing pressing block 3:
[0027] Those skilled in the art should be able to understand that the PCBA circuit module 4 includes a PCBA circuit board and a module housing 42 for encapsulating the PCBA circuit board. The module housing 42 is similar to a box with an open top. Inverting the module housing 42 onto the component surface of the PCBA circuit board and performing potting encapsulation forms the PCBA circuit module 4. Pins 41 extending outside the module housing 42 are provided at the edge of the PCBA circuit board;
[0028] A groove 12 is formed on one side surface of the bottom block 1. Refer to Figure 4 , the bottom block 1 includes a block body 11 with a groove 12 formed on its top surface. During use, the pins 41 at opposite ends of the PCBA circuit module 4 are placed on the edge of the groove 12, and the module housing 42 of the PCBA circuit module 4 can move along the direction of entering and exiting the groove 12. That is, at this time, the module housing 42 of the PCBA circuit module 4 is suspended above the groove 12;
[0029] The wire - pressing block 2 is used to press the pins 41 at both ends of the PCBA circuit module 4;
[0030] The board - removing pressing block 3 is used to apply a downward pressure to the module housing 42 of the PCBA circuit module 4.
[0031] During operation, place the PCBA circuit module 4 at the groove 12, with the PCBA circuit board on top and the module housing 42 below. When the wire pressing block 2 presses the pins 41 at the opposite ends of the PCBA circuit module 4 and the board removing pressing block 3 applies a downward pressure to the module housing 42, the module housing 42 has a tendency to move downward, while the pins 41 are pressed by the wire pressing block 2 and the PCBA circuit board has a tendency to remain stationary in place. Under the continuous downward pressure of the board removing pressing block 3, the module housing 42 is peeled off from the PCBA circuit board provided with the pins 41, and the module housing 42 drops into the groove 12. After peeling, the PCBA circuit board provided with the pins 41 is still pressed by the wire pressing block 2 against the top of the groove. Since the module housing 42 and the pins 41 are respectively subjected to forces in opposite directions by the board removing pressing block 3 and the wire pressing block 2, the whole module housing 42 drops into the groove 12 after peeling, and no additional force acts on the module housing 42, so that phenomena such as damage to the module housing 42 caused by clamping will not occur. Therefore, the appearance of the module housing 42 can be well protected during the disassembly process, the PCBA circuit board is not likely to break, and the disassembly success rate is high.
[0032] In some embodiments of the present invention, the opposite side walls of the groove 12 for accommodating the pins 41 are inwardly protruded to form bosses 13, see Figure 4 , which is convenient for placing or accommodating the pins 41, suitable for disassembling the PCBA circuit module 4 extending along the direction of the pins 41 on both sides of the module housing 42, and increasing the scope of use.
[0033] See Figure 3 , in some embodiments of the present invention, the number of the wire pressing blocks 2 is set to two, and the two wire pressing blocks 2 are arranged on the opposite sides outside the groove 12. During use, the pins 41 at both ends can be fixed separately to ensure the fixing effect.
[0034] In some embodiments of the present invention, the wire pressing block 2 and the bottom block 1 are tightly connected through a threaded structure, see Figure 3 , two second threaded holes 16 are opened on the bottom block 1, and the two second threaded holes 16 are symmetrically located on both sides of the groove 12. A through first connection hole 21 is opened in the middle of the wire pressing block 2, and the first connection hole 21 corresponds to the second threaded hole 16. When the wire pressing block 2 presses on the pins 41, a bolt passes through the first connection hole 21 and is threadedly engaged with the second threaded hole 16 to realize that the wire pressing block 2 presses the pins 41 tightly.
[0035] In some embodiments of the utility model, a placement groove 14 is provided on the top surface of the bottom block 1 to cooperate with the wire pressing block 2, so as to prevent the wire pressing block 2 from twisting when pressing the pin 41, thereby affecting the clamping effect. For example, when a bolt passes through the first connecting hole 21 and is threadedly matched with the second threaded hole 16, the bolt needs to be tightened. During this process, since the wire pressing block 2 is placed in the placement groove 14, the wire pressing block 2 can be prevented from rotating when the bolt is tightened, so that no relative movement occurs between the wire pressing block 2 and the pin 41, thereby ensuring the clamping effect. Preferably, the bottom surface of the placement groove 14 is flush with the top surface of the boss 13.
[0036] In some embodiments of the present invention, one end of the pressing block 2 is hingedly connected to the bottom block 1. Figure 6 That is, the wire pressing block 2 and the bottom block 1 are connected as a whole by a hinged connection. When in use, the wire pressing block 2 is flipped along the hinged part, and the other end of the wire pressing block 2, that is, the end away from the hinged part, is pressed on the pin 41. The first connecting hole 21 can also be threadedly matched with the second threaded hole 16 by a bolt passing through the first connecting hole 21 to achieve the clamping of the wire pressing block 2 on the pin 41. Preferably, the first connecting hole 21 is set as an oblong hole, which is convenient for clamping pins of different diameters, and when the bolt is turned to move upward and the mating relationship with the second threaded hole 16 is not disengaged, the wire pressing block 2 can still be flipped along the hinged part, so that the wire pressing block 2, the corresponding bolt, and the bottom block 1 are always connected as a whole during operation, reducing the number of scattered parts and facilitating operation.
[0037] In some embodiments of the present invention, the bottom of the board removal pressing block 3 applies force to the module housing 42 of the PCBA circuit module 4 through the pressing blocks 32 spaced apart from each other, see Figure 1 , 2 , 5, 6, the board removal pressing block 3 includes a connecting plate 31 for convenient force application, and two pressing blocks 32 spaced apart on one side of the connecting plate 31. When in use, the pressing blocks 32 are located at opposite sides of the module housing 42. When the module housing 42 and the pins 41 are peeled off, a clearance space is formed between the mutually spaced pressing blocks 32 to ensure that the peeling operation proceeds smoothly. Furthermore, the force application positions of the two pressing blocks 32 on the cross block housing 42 are located at opposite sides of the compressed pins 41.
[0038] In some embodiments of the present invention, a pressing groove 33 is provided at the inner edge of the bottom surface of the pressing block 32. When in use, the pressing groove 33 is stuck at the outer edge of the top surface of the module shell 42 to prevent the panel pressing block 3 from sliding during disassembly, thereby ensuring the success rate of disassembly.
[0039] In some embodiments of the present invention, the panel disassembly pressing block 3 and the bottom block 1 are connected and fastened by a threaded structure, and the fastening process is the process of applying force to the panel disassembly pressing block 3. Figure 2 , 5, 6. A through second connection hole 34 is formed in the connection plate 31 of the plate-removing pressing block 3, and a corresponding first threaded hole 15 is formed in the bottom block 1. When the force-applying part of the pressing block 32 is aligned with the module housing 42, a bolt passes through the second connection hole 34 and is in threaded engagement with the first threaded hole 15. During the process of screwing the bolt, the top of the bolt presses down the connection plate 31, so that the pressing block 32 applies a downward force to the module housing 42.
[0040] In some embodiments of the present invention, the plate-removing pressing block 3 and the bottom block 1 are connected and fastened through two threaded structures with parallel axes. The two threaded structures are symmetrically located on both sides of the groove 12. Refer to Figure 2 , 5 , 6. The number of the second connection holes 34 is two, which are symmetrically located on both sides of the two pressing blocks 32. Correspondingly, the number of the first threaded holes 15 is also two, which are symmetrically located on the outer sides of both sides of the groove 12. When the bolt is initially tightened in the corresponding first threaded hole 15, the forces on both sides of the connection plate 31 are balanced, that is, the two pressing blocks 32 apply forces to both sides of the template housing 42 simultaneously. When further tightened, the two bolts can be alternately and slightly screwed respectively, or the two bolts can be screwed synchronously, so that the forces applied by the top of the bolts to both sides of the connection plate 31 are always balanced, and the forces on both sides of the template housing 42 are always balanced during the plate-removing process, thereby ensuring the plate-removing effect.
[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
