Description

Technical Field

[0001] The utility model relates to the technical field of automatic processing of wiring boards, in particular to a clamp for wiring boards and pre-installation equipment for wiring boards. Background Art

[0002] During the automated pre-installation of the terminal block, the precise positioning of the terminal block is particularly important due to the high precision requirements of the components to be installed. This requires that the limit grooves on the tooling plate that fixes the terminal block have high precision, thereby reducing the gap between the inner wall of the limit groove and the terminal block.

[0003] However, in the prior art, the terminal block clamp structure and the manipulator are connected by hard connection, and the terminal block itself is a plastic product, and its appearance cannot guarantee high precision. In this way, when the clamp is clamping the terminal block and placing it on the tooling board, due to the poor precision of some terminal blocks, its appearance is difficult to match the limit groove on the tooling board, which can easily cause the terminal block and the tooling board to get stuck during the fixing process, thereby making it difficult for the terminal block clamp to install the terminal block in place, making it difficult to successfully complete the subsequent process content. Utility Model Content

[0004] In view of this, the utility model proposes a clamp for a terminal block and a pre-installation device for a terminal block, so as to solve the problem in the prior art that the terminal block is difficult to install in place due to the jamming between the terminal block and the tooling board during the process of installing the terminal block on the tooling board using the clamp for the terminal block.

[0005] According to one aspect of the utility model, a clamp for a wiring board is provided. The clamp for the wiring board includes: a mounting member, which is configured to be mounted on a manipulator; a connecting member, which is movably connected to the mounting member; a clamping member, which is connected to the connecting member, and the clamping member has two clamping ends that can be opened and closed, and the two clamping ends are used to enclose a clamping space for clamping the wiring board; a floating member, which includes an elastic member, which is located between the mounting member and the connecting member, and the two ends of the elastic member are respectively in contact with the mounting member and the connecting member, so that the clamping member can be floated relative to the mounting member.

[0006] In this way, during the process of installing the terminal block on the tooling plate, when the terminal block has poor precision and causes a blocking force to be generated between the terminal block and the tooling plate, on the one hand, the elastic member can act as a force unloader, thereby avoiding the problem of the terminal block and the tooling plate being stuck; on the other hand, during the downward pressing process, the elastic member can allow the clamping claw member to have a certain range of shaking space, so that the terminal block can enter the tooling plate more smoothly during the shaking process, thereby avoiding the problem of the terminal block being stuck during the process of installing it into the tooling plate, thereby greatly improving the success rate of the terminal block being smoothly installed into the tooling plate, and ensuring that the subsequent processes can proceed smoothly.

[0007] In a preferred embodiment, the floating member further comprises a guide member, one end of which is connected to the mounting member, the other end of which is passed through the connecting member and slidably connected to the connecting member, and an elastic member is provided on at least one side of the guide member.

[0008] In this way, the clamping claw member can be prevented from shaking too much during the process of fixing the terminal block and the tooling plate, thereby preventing the terminal block from falling out of the tooling plate. In this way, the success rate of successfully fixing the terminal block in the tooling plate can be improved.

[0009] In a preferred embodiment, the elastic member is located on the outer periphery of the guide member.

[0010] In this way, the elastic force of the elastic member can be more evenly applied, thereby improving the stability of the floating component.

[0011] In a preferred embodiment, the elastic member is a spring.

[0012] In this way, the structure is simple and easy to process and produce.

[0013] In a preferred embodiment, the connecting member includes a connecting body and a limit member connected to the connecting body, the limit member defines a connected accommodating space and a through hole, and the cross-sectional areas of the through hole and the accommodating space increase sequentially; the guide member includes a guide rod and a piston with outer diameters increasing sequentially, one end of the guide rod is connected to the mounting member, and the other end of the guide rod passes through the through hole and is connected to the piston, the guide rod and the through hole are slidably matched, and the piston is located in the accommodating space.

[0014] In this way, on the one hand, it is possible to prevent the clamping jaw member from shaking too much; on the other hand, the piston can prevent the guide rod from escaping from the through hole.

[0015] In a preferred embodiment, the clamping jaw assembly includes: a pneumatic clamping jaw, including a main body and two claw pieces movably arranged relative to the main body; two clamping members, respectively located on both sides of the pneumatic clamping jaw, and the two clamping members are correspondingly connected to the two claw pieces, and the clamping members form a clamping end.

[0016] In this way, the clamping jaw member can be adapted to different wiring boards with greatly different shapes, so that wiring boards with different shapes and sizes can be fixed in the tooling plate.

[0017] According to another aspect of the utility model, a pre-installation device for a wiring board is provided, comprising a body, a manipulator disposed on the body, and the above-mentioned clamp for the wiring board connected to the manipulator.

[0018] It can be seen from the above scheme that the clamping member is movably connected to the mounting member through the connecting member, and an elastic member is arranged between the mounting member and the connecting member, so that the clamping member can be floated relative to the mounting member. In this way, in the process of installing the terminal block on the tooling board, when the poor precision of the terminal block leads to a blocking force between the terminal block and the tooling board, on the one hand, the elastic member can play a role in unloading the force, thereby avoiding the problem of the terminal block and the tooling board being stuck; on the other hand, in the process of pressing down, the elastic member can allow the clamping member to have a certain range of shaking space, so that the terminal block can enter the tooling board more smoothly during the shaking process, so as to avoid the problem of the terminal block being stuck during the process of installing it into the tooling board, thereby greatly improving the success rate of the terminal block being smoothly installed into the tooling board, and ensuring that the subsequent processes can proceed smoothly.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0045] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0046] It should be noted that in the embodiment of the utility model, the installation component 1 is connected to the robot, and the robot drives the terminal block clamp to move, so that the clamping claw component 30 clamps the terminal block and moves it to the top of the tooling plate and then presses it down, thereby fixing the terminal block to the tooling plate.

[0047] like Figures 1 to 4As shown, the clamp for the wiring board includes a mounting member 1, a connecting member 20, a clamping member 30 and a floating member 40. The mounting member 1 is configured to be mounted on a manipulator; the connecting member 20 is movably connected to the mounting member 1; the clamping member 30 is connected to the connecting member 20, and the clamping member 30 has two clamping ends that can be opened and closed, and the two clamping ends are used to enclose a clamping space for clamping the wiring board; the floating member 40 includes an elastic member 41, which is located between the mounting member 1 and the connecting member 20, and the two ends of the elastic member 41 are respectively in contact with the mounting member 1 and the connecting member 20, so that the clamping member 30 can be arranged to float relative to the mounting member 1.

[0048] In the above technical solution, the clamping jaw member 30 is movably connected to the mounting member 1 through the connecting member 20, and an elastic member 41 is arranged between the mounting member 1 and the connecting member 20, so that the clamping jaw member 30 can be arranged floatingly relative to the mounting member 1. In this way, in the process of installing the terminal block on the tooling board, when the poor precision of the terminal block leads to a blocking force between the terminal block and the tooling board, on the one hand, the elastic member 41 can play a role in unloading the force, thereby avoiding the problem of the terminal block and the tooling board being stuck; on the other hand, in the process of pressing down, the elastic member 41 can allow the clamping jaw member 30 to have a certain range of shaking space, so that the terminal block can enter the tooling board more smoothly during the shaking process, so as to avoid the problem of the terminal block being stuck during the process of installing it into the tooling board, thereby greatly improving the success rate of the terminal block being smoothly installed into the tooling board, and ensuring that the subsequent processes can proceed smoothly.

[0049] Specifically, in the embodiments of the present invention, the manipulator includes but is not limited to a cylinder or an electric push rod or a mechanical arm.

[0050] like Figure 2 As shown, the floating member 40 further includes a guide member 42, one end of which is connected to the mounting member 1, and the other end of which is passed through the connecting member 20 and is slidably connected to the connecting member 20, and an elastic member 41 is provided on at least one side of the guide member 42. In this way, when the wiring board and the tooling board are fixed, if the wiring board and the tooling board are squeezed due to the difference in the appearance of the wiring board, the elastic member 41 will drive the clamping claw member 30 to shake. By providing the guide member 42, the clamping claw member 30 can be prevented from shaking too much during the process of fixing the wiring board and the tooling board, thereby preventing the wiring board from falling out of the tooling board, and thus, the success rate of successfully fixing the wiring board in the tooling board can be improved.

[0051] Preferably, in the embodiment of the present invention, the guide member 42 is connected to the mounting component 1 by welding.

[0052] like Figure 2As shown, the elastic member 41 is located at the outer periphery of the guide member 42. In this way, the elastic force of the elastic member 41 can be more balanced, thereby improving the stability of the floating member 40.

[0053] In one embodiment, a plurality of elastic members 41 may be arranged at intervals along the circumference of the guide member 42 .

[0054] like Figure 2 As shown, the elastic member 41 is a spring. In this way, the structure is simple and convenient for processing and production.

[0055] like Figure 2 As shown, the connecting member 20 includes a connecting body 21 and a limit member 22 connected to the connecting body 21, the limit member 22 defines a connected accommodating space 23 and a through hole 24, and the cross-sectional areas of the through hole 24 and the accommodating space 23 increase successively; the guide member 42 includes a guide rod 43 and a piston 44 with outer diameters increasing successively, one end of the guide rod 43 is connected to the mounting member 1, and the other end of the guide rod 43 passes through the through hole 24 and is connected to the piston 44, the guide rod 43 and the through hole 24 are slidably matched, and the piston 44 is located in the accommodating space 23.

[0056] Through the above arrangement, on the one hand, the guide rod 43 can guide the limit member 22 so that the clamping member 30 on the connecting body 21 can move back and forth along the axis of the guide rod 43, thereby avoiding the clamping member 30 from shaking too much; on the other hand, during the movement of the guide rod 43 in the through hole 24, the piston 44 can move in the accommodating space 23. Since the cross-sectional area of ​​the piston 44 is larger than the cross-sectional area of ​​the guide rod 43, and the cross-sectional area of ​​the accommodating space 23 is larger than the cross-sectional area of ​​the through hole 24, the piston 44 can prevent the guide rod 43 from escaping from the through hole 24.

[0057] Furthermore, through the above-mentioned arrangement, the connecting member 20 can also be movably connected to the guide member 42. In this way, the terminal block is pressed down by the clamping member 30. When the terminal block and the tooling plate contact and squeeze each other, the tooling plate will generate a reaction force to push the terminal block, the clamping member 30 and the connecting member 20 upward. Since the connecting member 20 and the guide member 42 are movably connected, the reaction force will cause the connecting member 20 to move upward, thereby causing a relative displacement of part of the guide member 42 and the limit member 22 in the accommodating space 23, thereby preventing the terminal block and the tooling plate from continuing to be squeezed, thereby avoiding the problem of the terminal block and the tooling plate being stuck.

[0058] Preferably, in the embodiment of the present invention, the connecting body 21 and the limiting member 22 are integrally formed.

[0059] Preferably, in the embodiment of the present invention, the guide rod 43 and the piston 44 are integrally formed.

[0060] It should be noted that, in the embodiment of the present invention, the cross-sections of the through hole 24 and the accommodating space 23 are perpendicular to the axis of the guide rod 43 .

[0061] Specifically, in the embodiment of the present invention, the limiting member 22 includes two L-shaped plate sections spaced apart from each other on the connecting body 21 , and the two L-shaped plate sections enclose the accommodating space 23 and the through hole 24 .

[0062] Preferably, in an embodiment of the utility model, the connecting member 20 also includes a supporting member 25 arranged on the limiting member 22, and the supporting member 25 is provided with an avoidance hole connected to the through hole 24, wherein the guide rod 43 is sequentially passed through the avoidance hole, the through hole 24 on the limiting member 22 and the accommodating space 23, one end of the elastic member abuts against the mounting member 1, and the other end of the elastic member abuts against the supporting member 25, so that the elastic member can be supported more stably.

[0063] like Figure 1 and Figure 3 As shown, the clamping member 30 includes: a pneumatic clamping member, including a main body and two claw pieces 32 movably arranged relative to the main body; two clamping members 33, respectively located on both sides of the pneumatic clamping member, and the two clamping members 33 are correspondingly connected to the two claw pieces 32, and the clamping members 33 form a clamping end. In this way, the clamping member 30 can be applied to different wiring boards with greatly different shapes, so that wiring boards with different shapes and sizes can be fixed in the tooling board.

[0064] It should be noted that in the embodiment of the utility model, the main body includes a solenoid valve 34 and an air valve 35. The opening and closing of the air valve 35 is controlled by the solenoid valve 34, and the opening and closing of the air valve 35 controls the switch of the air source, thereby controlling the opening and closing of the two claws 32, and then the two claws 32 can drive the two clamping parts 33 to clamp or loosen the terminal block, so as to be suitable for clamping terminal blocks of different sizes.

[0065] It should be noted that the specific structure and clamping principle of the pneumatic clamp are prior art and will not be described in detail here.

[0066] It should be noted that the clamp for the wiring board of the embodiment of the utility model achieves the following effects:

[0067] 1. The clamp for the terminal block of this embodiment can adapt to terminal blocks of different external dimensions. When the individual external dimensions of the terminal blocks differ greatly, the floating member 40 can accommodate the positioning deviation caused by the different sizes of the terminal blocks, so that the terminal blocks and the tooling plate can be smoothly installed in place, greatly reducing the failures during the installation and positioning of the terminal blocks, and enabling the automatic process to be completed smoothly.

[0068] 2. By reducing the failure rate during the installation of the terminal block, the time for manual handling of abnormalities can be saved, the production capacity of the automated line terminal block pre-installation station is ensured and labor costs are reduced.

[0069] The utility model also provides a pre-installation device for a wiring board, comprising a machine body, a manipulator arranged on the machine body and the clamp for the wiring board connected to the manipulator.

[0070] The above-mentioned pre-installed equipment for the wiring board has all the advantages of the above-mentioned fixture structure for the wiring board, which will not be described in detail here.

[0071] It can be seen from the above scheme that according to the terminal block clamp and the terminal block pre-installation equipment proposed by the utility model, the clamping claw member is movably connected to the mounting member through the connecting member, and an elastic member is arranged between the mounting member and the connecting member, so that the clamping claw member can be arranged floatingly relative to the mounting member. In this way, in the process of installing the terminal block on the tooling plate, when the poor precision of the terminal block leads to a blocking force between the terminal block and the tooling plate, on the one hand, the elastic member can play a role in unloading the force, thereby avoiding the problem of jamming between the terminal block and the tooling plate; on the other hand, in the process of pressing down, the elastic member can allow the clamping claw member to have a certain range of shaking space, so that the terminal block can enter the tooling plate more smoothly during the shaking process, so as to avoid the problem of jamming when the terminal block is installed in the tooling plate, thereby greatly improving the success rate of smoothly installing the terminal block into the tooling plate, and ensuring that the subsequent processes can proceed smoothly.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
