Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection and processing, and in particular to a transport mechanism for switching PCBA boards. Background Art

[0002] Defects in switch PCBA boards can generally be detected on the machine through automatic testing equipment. In the defect detection process of switch PCBA boards, the stability and life of the equipment are relatively high. Since the temperature of the PCBA board is very high when it comes out of the soldering furnace, the testing equipment needs to be able to withstand high temperatures. At the same time, the PCBA board needs to be moved many times during the operation of the equipment, and there are higher requirements for the handling claws that move the PCBA board. The handling claws need to be stable, resistant to high temperatures, and resistant to impact, so as to keep the PCBA board stable during the moving process.

[0003] In the prior art, ordinary clamps, adjustable cylinders, and silicone pads are usually used to form a clamping mechanism to clamp and move the PCBA board. The disadvantages of such a solution are poor anti-collision performance, unstable long-term operation, and the need for frequent maintenance and replacement of parts. For example, the patent document with application number 202322293966.6 discloses "a mechanical arm clamp for transporting circuit boards on a production line", which is used to clamp and transport circuit boards by providing a clamping plate on the clamping arm as a clamping structure. The clamping plate is provided with a rotating matching structure, which is prone to a decrease in matching accuracy when operating in a high temperature environment, affecting stability. Due to this structure with poor reliability, the circuit board is prone to slip during the transportation process.

[0004] It can be seen that the current circuit board handling solution still has room for improvement, and should be optimized to improve the reliability of the circuit board handling structure, improve temperature tolerance and stability during the handling process. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] To overcome at least one of the above-mentioned defects, the present invention provides a transport mechanism for switching PCBA boards.

[0006] In order to achieve the above-mentioned purpose, the transport mechanism for switching PCBA boards disclosed in the utility model can adopt the following technical solutions:

[0007] A transport mechanism for switching PCBA boards, comprising:

[0008] A moving module, used for driving the clamping jaw assembly to move in the lateral and longitudinal directions;

[0009] The clamping jaw assembly cooperates with the moving module and is used to open and close the PCBA board; the clamping jaw assembly includes a main body and a clamping block arranged on the main body and relatively opened and closed, the clamping block is formed with a limiting area for matching the main body, and a clamping groove for clamping the PCBA board is formed below the limiting area.

[0010] The above disclosed transport mechanism adjusts the position of the clamping jaw assembly by moving the module, and adjusts the clamping jaw assembly to a suitable position for subsequent clamping action; the clamping jaw assembly clamps the PCBA through the clamping block and then moves and transports it. During this process, it can withstand the high temperature of the PCBA board and maintain stable clamping, thereby avoiding the adverse effects of the high temperature environment on clamping and transporting.

[0011] Furthermore, in the present invention, the structure of the mobile module can be constructed in a variety of forms, which are not limited to a single one. Here, an optimization is made and one feasible option is proposed: the mobile module includes a transverse module, and a mounting frame is provided on the transverse module, and the mounting frame is driven by the transverse module to move back and forth. When such a solution is adopted, the transverse module generally moves back and forth in a straight line, driving the subsequent components to move synchronously.

[0012] Furthermore, in the present invention, the specific structure of the transverse module can be constructed in a variety of forms, which are not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the transverse module includes a transverse bottom rail and a transverse slide. The transverse slide moves back and forth along the transverse bottom rail under the control of the transverse driver, and the mounting frame is fixedly connected to the transverse base. When such a solution is adopted, the number of the transverse bottom rails can be singular, and it needs to be adjusted through the structure to keep the transverse slide moving smoothly; the number of the transverse bottom rails can also be set to multiple, and the transverse bottom rails arranged in parallel can play a better supporting and stabilizing role.

[0013] Furthermore, the transverse drive can be implemented in a variety of ways, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the transverse drive includes a driving screw, a driving screw hole is formed on the transverse slide corresponding to the driving screw, and the driving screw is driven by the transverse drive motor. When such a solution is adopted, the driving screw hole and the driving screw are threadedly matched, and when the driving screw rotates, force can be applied to the transverse slide to make it move.

[0014] Furthermore, the mobile module also drives the subsequent structure to realize lifting action. Here, we optimize and propose one feasible option: the mobile module also includes a lifting module arranged on the installation frame, the lifting module includes a lifting bottom rail and a lifting slide, the lifting slide moves up and down along the lifting bottom rail under the control of the lifting driver, and the lifting slide is connected to the clamping claw assembly and drives the clamping claw assembly to rise and fall synchronously. When such a solution is adopted, when the frame is lifted and lowered, the lifting module is driven to be lifted and lowered, thereby driving the PCBA board to be lifted and transported.

[0015] Furthermore, the lifting drive can adopt a variety of solutions, which are not limited to the only one. Here, we optimize and propose one feasible option: the lifting drive includes a lifting cylinder or a telescopic motor, the driving head of the lifting cylinder or the telescopic motor is connected to the lifting slider and drives it to move; the lifting cylinder or the telescopic motor is connected to the installation frame through a fixed plate. When such a solution is adopted, the lifting cylinder or the telescopic motor moves horizontally with the installation frame, and it can drive the lifting and lowering of the PCBA board by its own extension.

[0016] Furthermore, in the present invention, the structure of the clamp assembly is not limited to a single one, and an optimization is made here and one feasible option is proposed: the main body of the clamp assembly includes two connecting modules that are relatively opened and closed, the connecting modules are driven by a clamping driver to open and close, and the clamping block is connected to the connecting modules and opens and closes synchronously. When such a solution is adopted, the two connecting modules of the clamp assembly are made of high temperature resistant materials, including but not limited to metal materials such as alloy steel and aluminum alloy.

[0017] Furthermore, in the utility model, the clamping drive is used to drive the connecting module to approach clamping or separate, and it can be constructed in various forms and is not limited to a single form. Here, an optimization is performed and one of the feasible options is proposed: the clamping drive includes a clamping cylinder or a telescopic motor, and the two connecting modules include a fixed module and a movable module. The clamping cylinder or the telescopic motor is located on the fixed module and drives the movable module to approach or move away from the fixed module.

[0018] Furthermore, in order to better install and position, the handling mechanism is adjusted: it also includes a base assembly, and the base assembly includes a support member and a plurality of connecting seats arranged below the support member. When such a solution is adopted, the connecting seat can be a structural member such as an I-beam, and the support member can be a structural plate or other components.

[0019] Furthermore, the arrangement of the support member is not limited to a single one. In order to achieve better displacement, an optimization is made here and one feasible option is proposed: a cavity is formed between the support member and the lateral bottom rail, and the drive screw and the drive screw hole are matched in the cavity. When such a solution is adopted, the drive screw can be better accommodated and the protection of the drive screw can be improved.

[0020] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0021] The utility model clamps the PCBA board by the clamping claw assembly and adjusts the position by the displacement assembly, so that it is more stable and safe in the process of grabbing and carrying, avoids the decrease of clamping matching accuracy in a high temperature environment, and ensures the stability and reliability of carrying.
