Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to an adjustable PCB mounting fixture. Background Technology

[0002] PCB stands for Printed Circuit Board, which provides electrical connections and mechanical support for electronic components. PCBs mainly achieve their circuit functions by etching conductive lines on an insulating substrate. PCB surface mount technology (SMT) is the process of precisely mounting surface mount components to designated positions on the PCB, including solder paste printing, mounting, and reflow soldering. PCB SMT manufacturing plays an important role in improving the performance of electronic products and reducing production costs.

[0003] Existing technologies often have the following problems when used:

[0004] Existing technologies have problems in the surface mount production of PCBs longer than 180mm. The stopping space of a single surface mount machine can only support two PCBs, resulting in long PCB transport time and low PCB surface mount production efficiency. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable stop PCB mounting fixture, which can effectively solve the problem of wasted stop space due to excessively long PCB boards, resulting in long PCB board handling time and low PCB mounting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an adjustable PCB mounting fixture, comprising:

[0008] Fixture track;

[0009] A stop plate adjustment assembly includes several No. 1 induction through holes and several No. 2 induction through holes formed on two opposing side walls of the fixture track. Linear guide rails are fixedly connected to both opposing outer walls of the fixture track. A No. 1 linear slide plate and a No. 2 linear slide plate are slidably connected to the inner sides of the two linear guide rails respectively. A sensor generator is fixedly installed on the upper end face of the No. 1 linear slide plate, and a sensor receiver is fixedly connected to the upper end face of the No. 2 linear slide plate. The sensor generator and the sensor receiver are configured in conjunction. An adjustment drive component is fixedly connected to the outer wall of the fixture track.

[0010] The adjustment drive component is used to drive the sensor generator and sensor receiver to complete synchronized horizontal movement.

[0011] Furthermore, the adjustment drive component includes a fixed bracket fixedly connected to the outer wall of the fixture track, a low-speed motor fixedly installed in the middle of the fixed bracket, a transmission gear fixedly connected to the output end of the low-speed motor, and a transmission gear plate fixedly connected to the lower end face of the first linear slide plate, the transmission gear plate meshing with the transmission gear.

[0012] Furthermore, the adjustment drive component also includes two connecting brackets fixedly connected between the ends of the first linear slide plate and the second linear slide plate. The lower end of the connecting bracket is fixedly connected to a suspension bracket, and the upper end of the suspension bracket is rotatably connected to a roller via a pin. The lower end face of the fixture track is fixedly connected to a limit slide rail, and the roller is matched with the inner side of the limit slide rail.

[0013] Furthermore, the linear guide rail, the limiting slide rail, and the connecting bracket all adopt a concave structure.

[0014] Furthermore, the inner surfaces of the linear guide rail and the limiting slide rail are coated with a graphite lubricating coating.

[0015] Furthermore, the center points of the first sensing through-hole, the second sensing through-hole, the sensing generator, and the sensing receiver are all on the same horizontal plane.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention includes a stop plate adjustment component. A low-speed motor drives a transmission gear to rotate, and the meshing of the transmission gear and transmission tooth plate drives the first linear slide plate to move horizontally. This moves the sensor generator from its position corresponding to the first sensing through-hole to its position corresponding to the second sensing through-hole. Simultaneously, the first linear slide plate, via a connecting bracket, drives the second linear slide plate to move horizontally in sync, allowing the sensor receiver to move horizontally synchronously with the sensor generator. This ensures the stability of the pick-and-place machine's operation and prevents alarms caused by sensor movement. The sensor generator can then interact with the sensor receiver through the second sensing through-hole. When the sensor generator and receiver are aligned with the second sensing through-hole, the fixture track can hold one more board, saving PCB board transport time and effectively improving PCB placement production efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 4A PCB mounting fixture with adjustable stop plate includes: a fixture track 1 and a stop plate adjustment assembly. The stop plate adjustment assembly includes several first-order induction through holes 2 and several second-order induction through holes 3 formed on two opposing side walls of the fixture track 1. Linear guide rails 4 are fixedly connected to both opposing outer walls of the fixture track 1. A first-order linear slide plate 5 and a second-order linear slide plate 6 are slidably connected to the inner sides of the two linear guide rails 4, respectively. An induction generator 7 is fixedly installed on the upper surface of the first-order linear slide plate 5, and an induction receiver 8 is fixedly connected to the upper surface of the second-order linear slide plate 6. The induction generator 7 and the induction receiver 8 are configured in a matching manner. The center points of the first-order induction through holes 2, the second-order induction through holes 3, the induction generator 7, and the induction receiver 8 are all at the same level. On the surface, an adjustment drive component is fixedly connected to the outer wall of the fixture track 1; the adjustment drive component is used to drive the sensor generator 7 and the sensor receiver 8 to complete synchronous horizontal movement. The adjustment drive component includes a fixed bracket 9 fixedly connected to the outer wall of the fixture track 1. A low-speed motor 10 is fixedly installed in the middle of the fixed bracket 9. A transmission gear 11 is fixedly connected to the output end of the low-speed motor 10. A transmission tooth plate 12 is fixedly connected to the lower end face of the first linear slide plate 5. The transmission tooth plate 12 and the transmission gear 11 mesh with each other. The adjustment drive component also includes two connecting brackets 13 fixedly connected between the ends of the first linear slide plate 5 and the second linear slide plate 6. The linear guide rail 4, the limit slide rail 16 and the connecting brackets 13 are all set with a concave structure.

[0027] The low-speed motor 10 drives the transmission gear 11 to rotate. The meshing transmission of the transmission gear 11 and the transmission tooth plate 12 drives the first linear slide plate 5 to move horizontally, so that the sensor generator 7 can move from the position corresponding to the first sensing through hole 2 to the position corresponding to the second sensing through hole 3. At the same time, the first linear slide plate 5 can drive the second linear slide plate 6 to move horizontally synchronously through the connecting bracket 13, so that the sensor receiver 8 can move horizontally synchronously with the sensor generator 7, ensuring the stability of the pick-and-place machine and avoiding alarms caused by moving the sensor. The sensor generator 7 can complete the photoelectric interaction with the sensor receiver 8 through the second sensing through hole 3. When the sensor generator 7, the sensor receiver 8 and the second sensing through hole 3 are aligned, the fixture track 1 can hold one more board, thereby saving PCB board handling time and effectively improving PCB pick-and-place production efficiency.

[0028] Reference Figure 1 , Figure 3 and Figure 4 The lower end of the connecting bracket 13 is fixedly connected to the suspension bracket 14, and the upper end of the suspension bracket 14 is rotatably connected to the roller 15 via a pin. The lower end face of the fixture track 1 is fixedly connected to the limit slide rail 16. The inner surfaces of the linear guide rail 4 and the limit slide rail 16 are coated with a graphite lubricating coating. The roller 15 is matched with the inner side of the limit slide rail 16.

[0029] During the horizontal movement of the connecting bracket 13, the rollers 15 on the suspension leg 14 can slide and engage with the limiting slide rail 16 to ensure the stability of the horizontal movement of the connecting bracket 13, the first linear slide plate 5, and the second linear slide plate 6.

[0030] The working principle of this utility model is as follows:

[0031] In use, if the PCB board has a long length and the sensor generator 7 and sensor receiver 8 are positioned corresponding to the first sensing through-hole 2, the low-speed motor 10 can be started. The low-speed motor 10 drives the transmission gear 11 to rotate. The meshing transmission of the transmission gear 11 and the transmission gear plate 12 drives the first linear slide plate 5 to move horizontally, allowing the sensor generator 7 to move from the position corresponding to the first sensing through-hole 2 to the position corresponding to the second sensing through-hole 3. At the same time, the first linear slide plate 5 can drive the second linear slide plate 6 to move horizontally synchronously through the connecting bracket 13, allowing the sensor receiver 8 to move horizontally synchronously with the sensor generator 7. This ensures the stability of the pick-and-place machine's operation and avoids alarms caused by moving the sensors. The sensor generator 7 can then complete the photoelectric interaction with the sensor receiver 8 through the second sensing through-hole 3. When the sensor generator 7 and sensor receiver 8 are aligned with the second sensing through-hole 3, the fixture track 1 can hold one more board, thereby saving PCB board handling time and effectively improving PCB pick-and-place production efficiency.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
