As shown in Figures 1 to 3, this embodiment provides a PCB positioning tool for positioning PCB900, including a fixing module 100 and a silo module 200; the fixing module 100 includes a frame body 110, a stop plate 180 and a first positioning device 130 and a second positioning device 140 movably mounted on the frame body 110, the first positioning device 130 is slidably arranged on the frame body 110 along a first direction Y, the first positioning device 130 includes a first side push plate 131 and a first side push unit 132 fixedly connected to the first side push plate 131, the output end of the first side push unit 132 can move along the first direction Y, the second positioning device 140 is slidably arranged on the frame body 110 along a second direction X, the second positioning device 140 includes a second side push plate 141 and a second side push unit 142 fixedly connected to the second side push plate 141, the output end of the second side push unit 142 can move along the second direction X, the stop plate 180 0 is fixed to the frame body 110 and has a first surface and a second surface, the first direction Y is perpendicular to the first surface, and the second direction X is perpendicular to the second surface; wherein the first direction Y and the second direction X are perpendicular to each other and are both located in a horizontal plane; the silo module 200 includes a pallet 210 and a drive assembly 220, the drive assembly 220 can drive the PCB900 to move between the positioning plane and the transport plane along the vertical direction Z, the pallet 210 is used to carry the PCB900 located in the transport plane, and at least one guide plate 230 extending along the vertical direction Z is fixed to the pallet 210, when the PCB900 is located in the positioning plane, the first side push plate 131 or the first side push unit 132 pushes the PCB900 along the first direction Y to stop when the PCB900 contacts the first surface, and the second side push plate 141 or the second side push unit 142 pushes the PCB900 along the second direction X to stop when the PCB900 contacts the second surface.

The PCB positioning tool can perform positioning operations on the PCB900 in the first direction Y and the second direction X by means of the cooperation between the positioning device and the stop plate 180, so that the first surface and the second surface can play the role of stopping the PCB900 in the positioning operation, thereby achieving the positioning purpose in the horizontal plane. Moreover, the above design enables the PCB positioning tool to be compatible with the positioning operations of PCB900 of various sizes. The positioning device has the design of a side push plate and a side push unit at the same time, which can first use the side push plate to perform preliminary position limitation, and then use the side push unit to accurately position the PCB900. Through two consecutive positioning operations, the positioning progress of the PCB900 can be guaranteed, so that the PCB900 can be precisely positioned more accurately. The setting of the drive component 220 plays the role of moving the PCB900 between the positioning plane and the handling plane, ensuring that the positioning operation and the handling operation of the PCB900 can be completed smoothly, while also avoiding the position conflict between the components, and optimizing the structural layout of the PCB positioning tool. At the same time, the limitation of the guide plate 230 extending along the vertical direction Z can prevent the PCB 900 from having position deviation when the driving assembly 220 drives the PCB 900 to move along the vertical direction Z. The above structural improvements reduce the number of components that need to be replaced during iteration of the PCB positioning tooling, reduce the iteration cost, and expand the application scenarios of the PCB positioning tooling.

Specifically, it is common knowledge in the art that the adjustment accuracy of the thrust plate is lower than that of the side thrust unit, and will not be elaborated here.

The above-mentioned PCB positioning tool is used in the process of sucking PCB900 into the fixture on the SMT automation equipment. Compared with the traditional tool, the PCB positioning tool provided in this embodiment separates the traditional upper positioning plate and the bottom fixing plate, thereby improving the flexibility of the overall structure.

The PCB positioning tool is compatible with the following PCB900 sizes: length 10mm-150mm; width 10mm-190mm. The specific size can increase or decrease the compatible range according to actual needs. The specific compatible range is determined by the staff in this field according to the actual project. The determination method is the conventional technical means in this field and will not be elaborated here.

For example, the frame body 110 is provided with a slide rail, which is fixed to the stop plate 180. The positioning device further includes a slider, which is fixed to the corresponding side push plate. The slide rail and the slider are slidably matched to realize the sliding of the positioning device on the frame body 110. The specific structure of the slide rail and the slider is common knowledge in the art and will not be described in detail here.

In this embodiment, a first in-place detection unit 150 is also fixedly connected to the frame body 110. The first in-place detection unit 150 is used to detect whether the PCB 900 is located in the positioning plane. Specifically, the first in-place detection unit 150 is a photoelectric sensor.

With the setting of the photoelectric sensor, the position of the PCB900 in the vertical direction Z can be limited. By means of photoelectric induction, the positioning height of the PCB900 in the vertical direction Z can be controlled. The above design ensures the accurate positioning of the PCB900 in the vertical direction Z, and ensures that the PCB900 can be accurately located in the positioning plane during the positioning operation.

Setting up a photoelectric sensor to monitor the distance is a conventional technical means in this technical field. Its specific structure and working principle are common knowledge in this field and are well known to technicians in this field, so they will not be elaborated here.

Exemplarily, the support plate 210 is penetrated with an avoidance hole extending in the vertical direction Z, and the output end of the driving component 220 is fixedly connected with a push plate, which can carry the PCB900. The design of lifting the PCB900 with the push plate can meet the driving requirements of the PCB900 in the vertical direction Z; the lifting driving method can reduce the driving difficulty of the PCB900, facilitate the timely and accurate positioning operation, and also avoid the position conflict between the driving component 220 and the two positioning devices. The above design has a simple structure, small space occupation and low operating cost, which is conducive to the long-term stable operation of the PCB positioning tooling.

Furthermore, the positioning plane is higher than the conveying plane, and both the positioning plane and the conveying plane are parallel to the horizontal plane, the guide plate 230 is fixed to the upper plate surface of the support plate 210, and the drive assembly 220 is installed on the lower plate surface of the support plate 210. The above design defines the positions of the positioning plane and the conveying plane, optimizes the structural layout of the silo module 200, avoids the situation where the drive assembly 220 and the guide plate 230 have a position conflict due to an accident, and ensures the stable operation of the silo module 200.

Exemplarily, two guide plates 230 are provided, and the two guide plates 230 are symmetrically arranged about the axis of the avoidance hole. The symmetrical limitation of the two guide plates 230 about the axis of the avoidance hole limits the position of the PCB 900 on the support plate 210, reduces the risk of accidental positional displacement of the PCB 900, ensures that the drive assembly 220 can smoothly drive the PCB 900, and the two positioning devices can smoothly complete the positioning operation of the drive assembly 220.

In this embodiment, the first side push unit 132 and the second side push unit 142 are both cylinders. By fine-tuning the cylinders to push the PCB 900, the PCB 900 can be accurately positioned, thereby ensuring the accuracy of the positioning operation and the precise positioning effect of the PCB 900.

The present embodiment also provides a PCB positioning device, including a pick-and-place device and the above-mentioned PCB positioning tooling; the silo module 200 is movably installed on the fixed module 100, and the silo module 200 can move between the loading and unloading position and the positioning position relative to the fixed module 100. When the silo module 200 is located at the positioning position, the driving component 220 can drive the PCB 900; the pick-and-place device can place the PCB 900 on the silo module 200 located at the loading and unloading position, or take the PCB 900 on the silo module 200 located at the loading and unloading position.

The PCB positioning device is designed to move the silo module 200 between the loading and unloading position and the positioning position, so that the silo module 200 can complete the positioning operation of the PCB900 at the positioning position and complete the picking and placing operation of the PCB900 at the loading and unloading position. The above design avoids position conflicts in the positioning operation and the picking and placing operation, optimizes the structural layout of the PCB positioning device, and helps to improve the efficiency of precise positioning of the PCB900.

When the PCB positioning device is working, it is first necessary to select the corresponding push plate and the contoured support plate 210 according to the size of PCB900; then put the silo module 200 in place; the drive component 220 lifts the PCB900 until the first in-place detection unit 150 detects that the PCB900 is located in the positioning plane; first adjust the position of the two side push plates, and then adjust the position of the two side push units. After the adjustment is completed, start the PCB positioning device for testing.

In this embodiment, a conveyor belt 120 is further provided on the frame body 110, and a support plate 210 is placed on the conveyor belt 120. The support plate 210 is used to drive the silo module 200 to move back and forth between the loading and unloading position and the positioning position. With the arrangement of the conveyor belt 120, the relative position change between the silo module 200 and the fixed module 100 can be achieved. The conveying purpose achieved by using the conveyor belt 120 is simple and reliable, occupies little space and has high working stability.

Further, the conveyor belt 120 drives the silo module 200 along the third direction, and the fixed module 100 further includes a positioning and pushing unit 160 and a stop block which are relatively arranged along the fourth direction, the stop block being fixedly connected to the frame body 110, and the positioning and pushing unit 160 is used to push the support plate 210 along the fourth direction to stop when the support plate 210 contacts the stop block, wherein the third direction and the fourth direction are perpendicular to each other and are both located in a horizontal plane. Specifically, the positioning and pushing unit 160 is a cylinder; the third direction is parallel to the first direction Y, and the fourth direction is parallel to the second direction X. The pushing action of the positioning and pushing unit 160 on the support plate 210 can determine the relative position between the silo module 200 and the fixed module 100, and can effectively offset the position deviation generated in the process of the silo module 200 being driven by the conveyor belt 120, ensuring that the silo module 200 can be accurately located at the positioning position, and by limiting the position of the silo module 200, the relative position relationship between the guide plate 230 and the positioning device can be determined, ensuring that the positioning operation of the PCB 900 can be completed smoothly and accurately.

Exemplarily, a second in-place detection unit 170 is also installed on the frame body 110, and the second in-place detection unit 170 is used to detect whether the silo module 200 is located at the loading and unloading position. Specifically, the second in-place detection unit 170 is a photoelectric sensor.

With the setting of the photoelectric sensor, it is possible to detect the position of the silo module 200 at the loading and unloading position. By means of photoelectric sensing, it is possible to determine whether the silo module 200 can be picked up and placed, so that the PCB 900 placed on the pallet 210 is accurately in place, ensuring that the pick-and-place device can successfully complete the pick-and-place operation of the PCB 900.

Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
