Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically to a positioning device without a PIN positioning plate. Background Technology

[0002] Printed circuit boards (PCBs), also known as printed circuit boards, are important electronic components. They serve as the support for electronic components and the carrier for their electrical connections. PCB manufacturing involves panelizing customer-supplied PCs / sets into large PNLs for processing to improve production efficiency. The purpose of molding is to use programmable CNC milling machines (CNCs) to cut the required delivery unit size (PCS or SET) from the production parts according to the outline drawings.

[0003] In traditional positioning devices for pinless positioning milling plates, the lack of mechanical positioning references (such as pins) typically relies on visual recognition or mechanical alignment for positioning. Such devices are often limited by the computational latency of image processing algorithms, insufficient repeatability of mechanical structures, or the need for multiple trial-and-error adjustments, resulting in a significant reduction in positioning efficiency. Especially in the machining of multi-hole, high-precision milling plates, the repeated calibration and compensation processes further extend the production cycle, becoming a bottleneck restricting the overall efficiency of the equipment. Therefore, those skilled in the art provide a positioning device for pinless positioning milling plates to solve the problems mentioned in the background art. Utility Model Content

Two sets of second guide grooves are opened on the inner wall of the worktable corresponding to the top surfaces of the two sets of second racks. Clamping plates are fixedly connected to the surfaces of the first racks and second racks in the two sets of second guide grooves and the first guide grooves.

[0007] As a preferred embodiment of the above technical solution, soft pads are glued to the surface of the four sets of clamping plates facing the milling machine, and the area of ​​the soft pads is equal to the area of ​​the clamping plates.

[0008] As a preferred embodiment of the above technical solution, the input end of the motor is electrically connected to an external controller via a wire, and a storage box for storing the controller is provided on the side of the workbench.

[0009] As a preferred embodiment of the above technical solution, an adjustment assembly is provided on both sides of the clamping plate of the CCD camera.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4As shown, this utility model provides a technical solution: a positioning device for a PIN-free positioning plate, including a workbench 1, a cylinder 2 is provided on the top surface of the workbench 1, a milling machine 3 is fixedly connected to the output end of the cylinder 2, two sets of CCD cameras 4 are symmetrically arranged on the outer walls of both sides of the milling machine 3, a positioning component 5 for rapid positioning is provided on the workbench 1 below the CCD cameras 4, and two sets of positioning holes for testing are symmetrically opened on the surface of the workbench 1 on both sides of the milling machine 3.

[0023] By opening two sets of test positioning holes on the surface of the worktable 1 on both sides of the router 3, and then using the dummy process edge positioning holes for the first forming positioning and for electrical testing positioning hole testing, the production is carried out in two forming methods. After the first CNC router, the circuit is switched to electrical testing, and after the electrical testing, the circuit is routered again. The addition of the dummy process edge design without affecting the utilization rate of the board material improves the quality and production efficiency of the PCB production process.

[0024] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 as well as Figure 4 As shown, the positioning component 5 includes a movable compartment 51 fixedly connected to the bottom surface of the worktable 1. A motor 52 is fixedly connected to the bottom surface of the movable compartment 51. The output end of the motor 52 passes through the movable compartment 51, and a drive shaft 53 is fixedly connected to the output end of the motor 52. Two sets of gears 54 are symmetrically arranged on the outer wall of the drive shaft 53. Two sets of first sliding grooves 55 are symmetrically opened on the inner wall of the movable compartment 51 corresponding to the front and rear ends of one set of gears 54. A first rack 56 is slidably connected in both sets of first sliding grooves 55. The movable compartments 51 on both sides of the other set of drive shaft 53 are... Two sets of second sliding grooves 57 are symmetrically provided on the inner wall. A second rack 58 is slidably connected in each of the two sets of second sliding grooves 57. Two sets of first guide grooves 59 are provided on the inner wall of the worktable 1 corresponding to the top surfaces of the two sets of first racks 56. The two sets of first guide grooves 59 are staggered. Two sets of second guide grooves 510 are provided on the inner wall of the worktable 1 corresponding to the top surfaces of the two sets of second racks 58. Clamping plates 511 are fixedly connected to the surfaces of the first racks 56 and the second racks 58 in the two sets of second guide grooves 510 and the first guide grooves 59.

[0025] Specifically, the motor 52 drives the transmission shaft 53 and gear 54 to rotate, causing the two sets of gears 54 to act synchronously on the two sets of first racks 56 and second racks 58. This causes the two sets of first racks 56 and second racks 58 to slide in opposite directions within the first slide groove 55 and the second slide groove 57. Simultaneously, the first racks 56 and second racks 58 drive the clamping plate 511 to slide within the first guide groove 59 and the second guide groove 510, thereby achieving the purpose of quickly clamping the printed circuit board workpiece. In addition, the CCD camera 4 is used to electrically measure the position of the circuit board, thereby improving the positioning accuracy of the circuit board. At the same time, it effectively solves the problem of low positioning accuracy caused by relying solely on visual recognition or mechanical alignment in the existing technology.

[0026] As one implementation method in this embodiment, please refer to Figure 1 As shown, soft pads are glued to the surface of the four clamping plates 511 facing the screed machine 3, and the area of ​​the soft pads is equal to the area of ​​the clamping plates 511.

[0027] Specifically, by providing a soft pad on the clamping surface of the clamping plate 511, it is possible to prevent the clamping plate 511 from clamping the circuit board too tightly, thereby preventing damage to the surface of the circuit board caused by the clamping plate 511.

[0028] As one implementation method in this embodiment, please refer to Figure 2 As shown, the input terminal of motor 52 is electrically connected to an external controller via a wire, and a storage box for storing the controller is provided on the side of the workbench 1.

[0029] In practice, this allows staff to remotely operate the motor 52, and also enables the controller to be properly stored while operating the motor 52, preventing the controller from being lost.

[0030] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, adjustment components 6 are provided on the clamping plates 511 on both sides of the CCD camera 4. The adjustment components 6 include two slide rods 61 that are slidably disposed in the clamping plate 511. A limit plate 62 is fixedly connected to the side surface of the two slide rods 61 facing the milling machine 3, and the two slide rods 61 are respectively fixedly connected to the two ends of one side of the limit plate 62. A bearing 63 is fixedly connected to the side surface of the limit plate 62 facing the clamping plate 511. A threaded rod 64 is fixedly connected to the outer end surface of the bearing 63. The threaded rods 64 are all threadedly connected to the clamping plate 511.

[0031] Specifically, by rotating the threaded rod 64, the threaded rod 64 rotates within the clamping plate 511 and simultaneously rotates on the bearing 63. Then, the bearing 63 pushes the limiting plate 62, causing the limiting plate 62 to drive the sliding rod 61 to slide within the clamping plate 511, thereby achieving the purpose of adjusting the clamping tightness of the clamping plate 511.

[0032] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the surface of the threaded rod 64 facing away from the bearing 63 is pentagonal, and the outer wall of the bearing 63 is provided with anti-slip texture.

[0033] In practice, this design facilitates the rotation of bearing 63 by staff and reduces the risk of slippage when rotating bearing 63.

[0034] As one embodiment of this invention, there are two adjustment components 6, which are symmetrically arranged on two of the clamping plates 511, and the two limiting plates 62 are located on opposite sides of the two clamping plates 511.

[0035] It should be noted that the two clamping plates 511 equipped with the adjustment component 6 are arranged in parallel, while the other two clamping plates 511 arranged in parallel do not have the adjustment component 6.

[0036] Working principle: First, the controller starts the motor 52, which drives the transmission shaft 53 and gear 54 to rotate. The two sets of gears 54 act synchronously on the two sets of first racks 56 and second racks 58, causing the two sets of first racks 56 and second racks 58 to slide in opposite directions in the first slide groove 55 and the second slide groove 57. The first racks 56 and the second racks 58 also drive the clamping plate 511 to slide in the first guide groove 59 and the second guide groove 510, thereby achieving the purpose of quickly clamping the printed circuit board workpiece. Then, the CCD camera 4 is used to electrically measure the position of the circuit board, thereby improving the positioning accuracy of the circuit board. Next, the cylinder 2 drives the milling machine 3 to extend and retract, and the milling machine 3 divides the circuit board as a whole. This is the end. Without adding a fake process edge, a large board electrical test is required. After the large board electrical test, the CCD camera 4 and the milling machine 3 are used to mill the board piece by piece.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
