Description

Technical Field

[0001] The present invention relates to the technical field of board card assembly, and particularly relates to a board card assembly tooling and an assembly method. Background Art

[0002] A communication product with a backplane usually includes two parts: a frame backplane provided on a frame and a board card main body with its own backplane. The presentation of the board card main body with its own backplane on the frame product can be regarded as a state where "board card backplane + board card main board + frame backplane" are connected in sequence along a straight line direction. That is, on two opposite sides of the board card main board, there are respectively a plug and a guide seat for assembling and connecting with the frame backplane and the board card backplane. Correspondingly, on the frame backplane and the board card backplane, there are respectively a socket corresponding to the plug and a guide pin corresponding to the guide seat.

[0003] Currently, in normal production, in order to improve production efficiency, it is generally necessary to produce the frame and the board card main body separately, and finally complete the assembly of the two. That is, after the frame and the board card main body are respectively assembled, the board card main body is then assembled onto the frame backplane as a whole. Specifically: the operator usually needs to first place the board card main board on the board card main body with the board card backplane pre-assembled, and plug and assemble the board card main board and the board card backplane to complete the assembly of the board card main body; then, the assembled board card main body is assembled onto the frame backplane to complete the assembly of the communication product.

[0004] Among them, when performing the plug-in assembly of "board card backplane + board card main board", the usual operation method is: the operator usually needs to first place the board card main board on the board card main body with the board card backplane pre-assembled, and complete the pre-alignment of "board card backplane + board card main board" through the guide seat / guide pin; then, the operator presses against one side of the board card main body with the body, holds both sides of the tail end of the board card main board with both hands, and pulls back forcefully multiple times. By means of the pulling-back force and the reaction force of the operator's body on the board card main board, the plug-in assembly operation of "board card backplane + board card main board" is completed.

[0005] However, due to the large resistance when the board card main board is plugged into the board card backplane, and the directions of both the manually applied pulling-back force and the reaction force provided by the body are difficult to control, when using this assembly method to assemble the board card backplane and the board card main board, there are problems such as difficult assembly, inconvenient operation, and easy damage to the components connected to the board card backplane on the board card main body, which seriously affects the assembly efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a board card assembly tooling and an assembly method, which can very conveniently complete the assembly of the board card backplane and the board card main board, reduce the assembly difficulty, and at the same time avoid damaging the components on the board card main body, thereby meeting the requirements of high efficiency and stable quality.

[0007] To achieve the above object, the present invention provides a board assembly tooling, which includes a horizontally arranged rectangular pallet. An upwardly bent cross beam is provided on one side edge of the pallet, and a fixing member for horizontally fixing the pallet is provided on the other side edge. On the side wall of the cross beam close to the inner side of the pallet, a protection block is convexly provided, which corresponds one by one to the guiding pins on the back plate of the frame and can prevent the plug-ins of the main board of the board from contacting the cross beam.

[0008] As a further improvement of the present invention, a tooling guiding pin detachably inserted and matched with the guiding seat of the main board of the board is provided on the side wall of the protection block far from the cross beam.

[0009] As a further improvement of the present invention, on the edges of the pallet at both ends of the cross beam, upwardly bent guiding plates for guiding the insertion of the main board of the board and the back plate of the board are provided.

[0010] As a further improvement of the present invention, protective films are covered on the opposite surfaces of the two guiding plates.

[0011] As a further improvement of the present invention, a protective film is covered on the upper surface of the pallet.

[0012] As a further improvement of the present invention, the fixing member is a hanging groove formed by two right-angle bends downward along the edge of the pallet.

[0013] A board assembly method includes the following steps:

[0014] S1. Horizontally place the pallet on the workbench and hook the hanging groove on one side edge of the workbench.

[0015] S2. Horizontally place the board body pre-installed with the back plate of the board on the pallet, and horizontally place the main board of the board on the board body. At this time, pre-alignment is achieved between the main board of the board and the back plate of the board through the guiding seat and the guiding pin, and pre-alignment is achieved between the board body and the cross beam through the guiding seat and the tooling guiding pin.

[0016] S3. The operator horizontally moves the board body from the pallet towards the cross beam side. Under the thrust, the board body drives the main board of the board forward, and the guiding seat and the guiding pin between the main board of the board and the back plate of the board start to be inserted in alignment, and the guiding seat and the tooling guiding pin between the main board of the board and the cross beam start to be inserted in alignment.

[0017] S3. The operator continues to push the board body. When the protection block touches the end face of the guiding seat of the main board of the board, the reaction force generated by the cross beam will push the main board of the board back, and finally the insertion assembly of the main board of the board and the back plate of the board is completed.

[0018] As a further improvement of the present invention, in step S3, by arranging guiding plates on both sides of the pallet, the translation direction of the board body is guided.

[0019] As a further improvement of the present invention, in step S3, the friction between the board body and the contact surfaces of the guide plates and the pallet is reduced by protective films on the opposing surfaces of the two guide plates and the upper surface of the pallet, thereby protecting the board.

[0020] As a further improvement of the present invention, the operator pushes the board body horizontally from the side of the support plate where the hanging groove is provided.

[0021] Compared with the prior art, the advantages of the board assembly tool and assembly method of the present invention are:

[0022] 1. In this assembly tool, when the operator pushes the board body, the fixing of the support plate by the fixing parts and the reaction force transmitted by the protection block during the movement of the board body, the staff only needs to push the board body to complete the plug-in of the board motherboard and the board backplane. At the same time, because the protection block can support the guide seat of the board body during the assembly process and prevent the plug-in of the board motherboard from contacting the crossbeam, it can also prevent the components on the board body connected to the board backplane from being damaged by force. Therefore, this assembly tool and its assembly method can easily complete the assembly of the board backplane and the board motherboard, reduce the difficulty of assembly, and protect the components on the board body connected to the board backplane, thereby meeting the requirements of high efficiency and stable quality.

[0037] Embodiment

[0038] As Figures 1-3 shown, a board card assembly tool provided by the present invention includes a horizontally arranged rectangular pallet 1. Specifically, the pallet 1 is a long board extending along the insertion and assembly direction of the board card main board and the board card backplane. Among them, a cross beam 2 bent upward is installed on the edge of one short side of the pallet 1 through a stainless steel stud, and a fixing member for horizontally fixing the pallet 1 is provided on the edge of the other short side. The fixing member is a hanging groove 11 formed by two right-angle bends downward along the edge of the pallet 1, and the hanging groove 11 and the pallet 1 are of an integral structure. In this embodiment, both the pallet 1 and the hanging groove 11 are processed by sheet metal of 1.0 mm galvanized steel plate, which has the advantages of light weight, high strength, low cost, and being suitable for customization. The cross beam 2 is processed by sheet metal of 1.5 mm galvanized steel plate and is riveted to install stainless steel studs.

[0039] At the same time, a protection block 21 corresponding to the guiding pins on the frame backplane one by one and capable of preventing the plug-ins of the board card main board from contacting the cross beam 2 is convexly provided on the side wall of the cross beam 2 close to the inner side of the pallet 1. A tooling guiding pin 22 detachably inserted and matched with the guiding seat of the board card main board is provided on the side wall of the protection block 21 away from the cross beam 2. In this embodiment, the protection block 21 is a custom-processed metal block. For example, the protection block 21 can be processed by an aluminum block. The tooling guiding pin 22 is selected as a standard part matching the guiding seat on the board card main board. At the same time, the specific setting quantity and position of the protection block 21 and the tooling guiding pin 22 should be completely consistent with the distribution of the guiding pins on the frame backplane, so as to be able to simulate the alignment of "board card main board + frame backplane". Moreover, in order to prevent the plug-ins of the board card main board from contacting the cross beam 2, the depth dimension of the protection block 21 is 3 mm - 10 mm larger than the depth difference between the longest protruding plug at the end of the board card main board and the end face of the guiding seat.

[0040] When the board card main board and the board card backplane are inserted and assembled through this assembly tool, there are two sets of dynamically matched guiding pins and guiding seats. Among them, the first set realizes the alignment of "board card backplane + board card main board" through the dynamic cooperation of the guiding seat and the guiding pin between the board card main board and the board card backplane; the second set realizes the alignment of "board card main board + assembly tool" or simulates the alignment of "board card main board + frame backplane" through the dynamic cooperation of the guiding seat and the tooling guiding pin 22 between the board card main board and the cross beam 2 of the assembly tool, by setting the tooling guiding pin 22 corresponding to the guiding pins on the frame backplane one by one.

[0041] In this assembly tooling, when the operator pushes the board card main body, through the fixation of the support plate 1 by the hanging groove 11 and the reaction force transmitted by the protection block 21 during the movement of the board card main body, the staff only needs to push the board card main body to complete the insertion of the board card main board and the board card backplane. At the same time, since the protection block 21 can hold the guide seat of the board card main body during the assembly process and prevent the plug-in components of the board card main board from contacting the cross beam 2, it can also avoid damage to the components connected to the board card backplane on the board card main body. Therefore, this assembly tooling and its assembly method can very conveniently complete the assembly of the board card backplane and the board card main board, reduce the assembly difficulty, and protect the components connected to the board card backplane on the board card main body, thus meeting the requirements of high efficiency and stable quality.

[0042] Moreover, in order to guide the insertion assembly of the board card main board and the board card backplane, upwardly bent guide plates 3 for guiding the insertion of the board card main board and the board card backplane are provided on the edges of the support plates 1 at both ends of the cross beam 2. The guide plates 3 can play a role in limiting and guiding the insertion assembly path of the board card main board and the board card backplane, thereby avoiding deviation and further causing damage to the components.

[0043] In this embodiment, in order to reduce the friction between the board card main body and the tooling and make the assembly more smooth, protective films are covered on the opposite surfaces of the two guide plates 3. A protective film is covered on the upper surface of the support plate 1. In this embodiment, the protective film is made of a PVC film (polyvinyl chloride film), such as a colorless or pure color GE film. The thickness of the protective film should be determined according to the specific installation height position of the tooling guide pin 22 so that the tooling guide pin 22 can accurately insert into the guide seat of the board card main board.

[0044] In addition, regarding a board card assembly method, it includes the following steps:

[0045] S1. Horizontally place the support plate 1 on the workbench and hook the hanging groove 11 on one side edge of the workbench;

[0046] S2. Horizontally place the board card main body pre-installed with the board card backplane on the support plate 1 and horizontally place the board card main board on the board card main body. At this time, the board card main board and the board card backplane are pre-aligned through the guide seat and the guide pin, and the board card main body and the cross beam 2 are pre-aligned through the guide seat and the tooling guide pin 22;

[0047] S3. The operator pushes the board card main body horizontally from the support plate 1 towards the cross beam 2 side. Under the thrust, the board card main body drives the board card main board forward, and the guide seat and the guide pin between the board card main board and the board card backplane start to be aligned and inserted, and the guide seat between the board card main board and the cross beam and the tooling guide pin 22 start to be aligned and inserted;

[0048] S3. The operator continues to push the board main body. After the protection block 21 abuts against the end face of the guide seat of the board main board, the reaction force generated by the cross beam 2 will push the board main board backward, and finally complete the plug-in assembly of the board main board and the board backplane.

[0049] In step S3 of this embodiment, by providing guide plates 3 on both sides of the pallet 1, the translation direction of the board main body is guided. At the same time, in step S3, the friction between the contact surfaces of the board main body and the guide plates 3 and the pallet 1 is also reduced by the protective films on the opposite surfaces of the two guide plates 3 and the upper surface of the pallet 1. Moreover, the operator horizontally pushes the board main body from the side of the pallet 1 provided with the hanging groove 11.

[0050] The present invention has been described in conjunction with the best embodiments, but the present invention is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations made according to the essence of the present invention.
