Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, and specifically relates to an automatic adjustment mechanism for board feeding. Background Technology

[0002] In the electronics manufacturing industry, the circuit board loading process plays a crucial role in the efficiency and quality of the entire production process. Many traditional loading methods rely on manual operation, requiring manual placement of circuit boards one by one into designated positions. This method is not only inefficient and difficult to meet the needs of large-scale production, but also suffers from poor consistency and accuracy in manual operation, which can easily lead to deviations in the placement of the boards and affect the accuracy of subsequent processing and testing procedures.

[0003] Currently, most automated material handling equipment has relatively simple and basic adjustment mechanisms, capable only of simple lifting or translating of materials, and unable to make precise adjustments to materials in multiple directions. For example, when materials are placed on a stacking platform for loading, existing equipment often cannot adequately handle potential positional shifts in the materials. If the initial placement of the materials is off, it may lead to inaccurate positioning during subsequent processing such as soldering, surface mounting, and testing, thereby affecting the yield of circuit boards. Utility Model Content

[0005] Therefore, the technical solution of this utility model is: an automatic adjustment mechanism for substrate loading, including a base, on which a liftable stacking platform is provided; a vertically arranged push rod is provided on the base, the push rod can move along the X-axis direction, and a first long slot for the push rod to pass through is provided on the stacking platform; a first push block that moves along the X-axis direction and a second push block that moves along the Y-axis direction are provided above the base.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the base is provided with a first side plate and a second side plate, which together with the stacking platform form a storage area; the first pusher block and the second pusher block are located on the top of the first side plate and the second side plate, respectively, and extend horizontally into the storage area.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the outer wall of the second side plate is provided with a second slide rail, and the outer end of the second pusher block is provided with a second sliding seat, which slides in cooperation with the second slide rail; the outer wall of the second side plate is also provided with a second driving component that drives the second pusher block to slide along the second slide rail.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the base is provided with a third slide rail arranged along the X-axis, and the bottom of the push rod is provided with a third sliding seat that slides in cooperation with the third slide rail; a second long slot is provided below the first side plate, and one end of the third sliding seat extends out from the second long slot and is connected to the third drive assembly on the outer side of the bottom of the first side plate.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the first drive component, the second drive component, and the third drive component have the same structure, each including a drive motor, a belt, and a pulley assembly. The first sliding seat, the second sliding seat, and the third sliding seat are all driven by the drive motor through the belt and move along the first slide rail, the second slide rail, and the third slide rail.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the first sliding seat, the second sliding seat, and the third sliding seat are all provided with sensing plates, and the first side plate, the second side plate, or the base is provided with multiple sensors that work in conjunction with the sensing plates.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: a guide column is provided below the stacking platform, and a guide hole is provided on the base for the guide column to pass through; a fourth drive assembly is provided on the base to drive the stacking platform to rise and fall.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] An automated structure is used for substrate loading. The substrates are raised using a liftable stacking platform, allowing the stacked substrates to enter the upper clamping position in sequence. The coordinated movement of each pusher block and pusher rod can quickly adjust the position of the substrates, greatly improving the loading speed and accuracy, meeting the needs of large-scale production, effectively shortening the production cycle, and improving overall production efficiency.

[0016] The substrate is coarsely adjusted by using a pusher rod that can move along the X-axis. The first pusher block and the second pusher block move along the X-axis and Y-axis respectively to finely adjust the top substrate. This can effectively correct the positional deviation of the substrate that may occur on the stacking table, and ensure that the substrate is accurately positioned when it enters the subsequent processing and inspection processes. This helps to improve the accuracy of processes such as soldering, chip mounting and inspection, thereby improving the yield of circuit boards.

[0017] By setting sensing plates on the first sliding seat, the second sliding seat, and the third sliding seat, and setting multiple sensors that work in conjunction with them on the first side plate, the second side plate, or the base, the position of the pusher block and the pusher rod can be accurately detected and fed back, thereby realizing intelligent control of the mechanism and further improving the accuracy and reliability of substrate position adjustment during the feeding process.

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature.

[0026] See the attached figures. The automatic substrate loading adjustment mechanism described in this embodiment includes a base 1, on which a first side plate 11 and a second side plate 12 are provided. A liftable stacking platform 2 is provided in the middle of the base 1. The first side plate 11 and the second side plate 12 together with the stacking platform 2 form a storage area. The substrates can be stacked on the stacking platform 2. The lifting stacking platform 2 is used to raise the substrates to the clamping position in sequence, which facilitates automatic loading. A substrate positioning detection sensor 13 is provided at the clamping position, which can be used to detect whether the substrate is in position. The substrate positioning detection sensor 13 can be a photoelectric sensor.

[0027] The stacking platform 2 is provided with a guide column 21 below it, and the base 1 is provided with a guide hole 14 for the guide column 21 to pass through. The guide column 21 cooperates with the guide hole 14 to play a guiding role during the lifting and lowering of the stacking platform 2, ensuring that the lifting and lowering of the stacking platform 2 is stable. The base 1 is provided with a fourth drive assembly 22 to drive the stacking platform 2 to lift and lower. The fourth drive assembly 22 can be a vertical gear and rack lifting structure, including a fourth drive motor 23, a drive gear and a rack 24; or other commonly used lifting mechanisms can be used, as long as they can drive the stacking platform 2 to lift and lower, and can accurately control the rising and falling height of the stacking platform 2 to meet different loading requirements.

[0028] The stacking platform 2 is a plate-shaped structure. It has a first elongated slot 25 along the X-axis, within which a movable push rod 3 is installed. The push rod 3 is vertically positioned. The base 1 has a third slide rail 15 along the X-axis. A third sliding seat 31 is located at the bottom of the push rod 3, and the third sliding seat 31 slides in conjunction with the third slide rail 15. A second elongated slot 16 is located below the first side plate 11. One end of the third sliding seat 31 extends from the second elongated slot 16 and connects to a third drive assembly 32 on the outer side of the bottom of the first side plate 11. Simultaneously, a third sensing element 33 is provided at the extended end of the third sliding seat 31. Multiple third sensor seats 34 are provided on the base 1 to detect the position of the third sensing element 33, enabling precise detection and feedback of the push rod 3's position.

[0029] The third drive assembly 32 includes a third drive motor 35, a third belt 36, and a third pulley group 37. The end of the third sliding seat 31 extends out of the second long slot 16 and is fixed on the third belt 36. The third drive motor 35 drives the belt 36 to move the third sliding seat 31 along the third slide rail 15, so that the push rod 3 can push the substrates stacked on the stacking platform 2 towards the second side plate 12 (i.e., the X-axis direction) from the outside, and make a coarse adjustment of the position of the substrates.

[0030] The base 1 is provided with a first pusher block 4 that moves along the X-axis and a second pusher block 5 that moves along the Y-axis. The first pusher block 4 and the second pusher block 5 are located at the top of the first side plate 11 and the second side plate 12, respectively, and can extend horizontally into the placement area to finely adjust one or two substrates at the top of the substrate in the X-axis and Y-axis directions. That is, the first pusher block 4 can push the substrate towards the second side plate 12 so that the substrate abuts against the second side plate 12; at the same time, the second pusher block 5 can push the substrate towards the first side plate 11 so that the substrate abuts against the first side plate 11, thereby adjusting the position of the substrate so that it can be clamped and loaded smoothly.

[0031] Meanwhile, in order to avoid motion interference between the push rod 3 and the first push block 4, a clearance groove 41 is provided on the lower end face of the first push block 4, and the top of the push rod 3 can pass through the clearance groove 41 so that the two do not interfere with each other.

[0032] The outer wall of the first side plate 11 is provided with a first slide rail 17, and the outer end of the first pusher block 4 is provided with a first sliding seat 42, which slides in cooperation with the first slide rail 17. The outer wall of the first side plate 11 is also provided with a first driving assembly 43 that drives the first pusher block 4 to slide along the first slide rail 17. The first driving assembly 43 includes a first driving motor 44, a first belt 45, and a first pulley group 46. The end of the first sliding seat 42 is fixed on the first belt 45. The first driving motor 44 drives the first belt 45 to move the first sliding seat 42 along the first guide rail 17, so that the first pusher block 4 can push the uppermost substrate of the stacking platform 2 towards the second side plate 12 from the outside (i.e., in the X-axis direction) to finely adjust the position of the substrate. At the same time, the first sliding seat 42 is provided with a first sensing plate 47, and the first side plate 11 is provided with a plurality of first sensors 48 that work in cooperation with the first sensing plate 47, which can accurately detect and provide feedback on the position of the first pusher block 4.

[0033] Similarly, the outer wall of the second side plate 12 is provided with a second slide rail 18, and the outer end of the second pusher block 5 is provided with a second sliding seat 51, which slides in cooperation with the second slide rail 18; the outer wall of the second side plate 12 is also provided with a second drive assembly 52 that drives the second pusher block 5 to slide along the second slide rail 18. The second drive assembly 52 includes a second drive motor 53, a second belt 54, and a second pulley group 55. The end of the second sliding seat 51 is fixed on the second belt 54. The second drive motor 53 drives the second belt 54 to move the second sliding seat 51 along the second slide rail 18, so that the second pusher block 5 can push the uppermost substrate of the stacking platform 2 towards the first side plate 11 (i.e., the Y-axis direction) from the outside, and finely adjust the position of the substrate. At the same time, the second sliding seat 51 is provided with a second sensing plate 56, and the second side plate 12 is provided with a plurality of second sensors 57 that work in cooperation with the second sensing plate 56, which can accurately detect and provide feedback on the position of the second pusher block 5.

[0034] In the initial state, the stacking platform 2 is at its lowest position, and the pusher rod 3, the first pusher block 4, and the second pusher block 5 are all at the outermost layer (i.e., the position furthest from the boundary line between the first side plate 11 and the second side plate 12). Then, the substrate to be processed is placed on the stacking platform 2. After placement, the pusher rod 3 moves all the substrates from the outside towards the second side plate 12 to perform coarse adjustment of the substrates.

[0035] The substrate positioning detection sensor 13 at the clamping position detects whether the substrate is in position. If the substrate is not in position, the fourth drive component 22 drives the stacking table 2 to rise and send the uppermost substrate into the clamping position. When the substrate positioning detection sensor 13 detects the substrate, the first drive component 43 and the second drive component 52 are activated, driving the first pusher block 4 and the second pusher block 5 to move toward the uppermost substrate, pushing the uppermost substrate to abut against the first side plate 11 and the second side plate 12, thereby accurately adjusting the substrate position, greatly improving the feeding speed and feeding accuracy, meeting the needs of large-scale production, effectively shortening the production cycle, and improving the overall production efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
