Description

Technical Field

[0001] This application belongs to the field of circuit board processing technology, specifically relating to a circuit board processing equipment. Background Technology

[0002] Traditional circuit board processing equipment still uses a single-axis machining method to process the corresponding table area, resulting in extremely low processing efficiency and long processing times that cannot meet the growing demands of users and manufacturers for circuit boards. To improve production speed, most circuit board manufacturers currently use a copy layout method when mass-producing circuit boards. This involves copying the entire layout in the X and Y directions with offsets based on the initial layout, resulting in a matrix layout structure. This layout style is very suitable for mass production.

[0003] However, it places high demands on the precision of circuit board processing equipment. During the processing, two or more spindles are used to process a PCB board at the same time. It is required that the X and Y direction spacing of the two or more spindles corresponding to each PCB board be equal. Due to the existence of processing errors and assembly errors, it is impossible to guarantee that the X and Y direction spacings are equal, which will cause the processing holes on the PCB board to be misaligned, resulting in the scrapping of the PCB board.

[0004] Existing circuit board processing equipment typically uses a semi-circular spindle clamp and a spindle sleeve for secure fixing. The spindle clamp is fixed to the Z-axis base plate and is configured to be driven by a motor, causing it to move up and down on the Z-axis base plate to perform drilling and milling operations on the circuit board. After the spindle is clamped, the common fixing method makes the spindle non-adjustable in the Y direction, resulting in different absolute coordinates of the machining centers between each spindle. This leads to manufacturing errors when multiple spindles process simultaneously. The existing spindle mounting method cannot meet the production demand of simultaneously drilling holes in a single board material using multiple spindles to improve processing efficiency. Therefore, there is an urgent need for a device that can keep the absolute coordinates of the machining centers between multiple spindles close to or identical to improve the efficiency of circuit board processing. Summary of the Invention

[0005] Purpose of the invention: This application provides a circuit board processing equipment, which aims to overcome the technical problem that when multiple spindles process a board simultaneously, the spindles cannot be adjusted in the Y direction, making it impossible to ensure that the coordinates of the processing centers of each spindle remain the same.

[0006] Technical solution: A circuit board processing equipment according to an embodiment of this application includes: a crossbeam;

[0007] A processing component for processing circuit boards, wherein the processing component is connected to the crossbeam by an inclined guide rail, and the processing component can slide obliquely relative to the crossbeam along the inclined guide rail;

[0008] An adjustment component is provided at the lower end of the processing component and is used to adjust the moving distance of the processing component along the inclined guide rail.

[0009] Optionally, in one of the circuit board processing devices, the inclined guide rail is configured such that the processing assembly moves obliquely downward or obliquely upward relative to the crossbeam in the vertical direction.

[0010] Optionally, in one of the circuit board processing devices, the inclined guide rail includes a first slider and a second slider, and the first slider and the second slider are connected by an inclined sliding connection.

[0011] Optionally, in one of the circuit board processing devices, the processing assembly includes a base plate and a spindle, the base plate being held vertically, the inclined guide rail being connected to the side of the base plate near the crossbeam, and the spindle being connected to the side of the base plate away from the crossbeam.

[0012] Optionally, in one of the circuit board processing devices described above, the inclined guide rail is detachably disposed between the base plate and the crossbeam.

[0013] Optionally, in one of the circuit board processing devices, the processing assembly further includes a spindle clamp, which fixes the spindle to the pressure cap. The spindle clamp is located on the side of the base plate away from the crossbeam. A vertical slide rail is provided between the spindle clamp and the base plate, and the spindle clamp can move up and down along the vertical slide rail on one side of the base plate.

[0014] Optionally, in one of the circuit board processing devices, the adjustment assembly includes an adjustment bolt and an adjustment base. The adjustment bolt is installed on the adjustment base and can move up and down within the adjustment base. The adjustment base is located below the base plate. The upper end of the adjustment bolt passes through the adjustment base and abuts against the bottom of the base plate. The adjustment bolt is used to move up and down to adjust the position of the base plate in the vertical direction.

[0015] Optionally, in one of the circuit board processing devices described, the adjusting bolt is a fine-thread bolt.

[0016] Optionally, one of the circuit board processing devices further includes a measuring component for measuring the distance the processing component travels along the inclined guide rail.

[0017] Optionally, in one of the circuit board processing devices, a measuring component is further included, the measuring component including a grating ruler and a reading head, the grating ruler and the reading head being located on the base plate and the adjusting base respectively, for reading the movement distance of the base plate.

[0018] Beneficial effects: By adding a set of inclined guide rails between the Z-axis base plate and the crossbeam, the base plate can slide obliquely relative to the crossbeam, generating displacement in both the Z and Y axes during this oblique sliding process. The spindle is connected to the base plate, and a small adjustment mechanism in the Z-axis direction allows for slight adjustments to the base plate, thereby causing changes in the Y-axis direction and adjusting the spindle's positional deviation in that direction. Adjusting the Y-axis position of each spindle individually ensures consistency across all spindles, reducing machining errors and decreasing the scrap rate. Attached Figure Description

Detailed Implementation

[0025] The circuit board processing equipment proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clarify the explanation of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different figures may emphasize different aspects and sometimes use different scales.

[0026] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish similar objects in order to describe embodiments of the invention, and are not used to describe a specific order or sequence. It should be understood that such uses of terminology are interchangeable where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] This disclosure provides a circuit board processing device, including a base, a crossbeam, processing components, a worktable, etc. The worktable is disposed on the upper surface of the base for placing a PCB board to be processed. The crossbeam is mounted on the base above the worktable. Multiple processing components are disposed on the crossbeam and located above the processing platform. The multiple processing components are arranged along a first direction (X-axis direction) of the base. The worktable moves on the base along a second direction (Y-axis direction). The crossbeam is mounted above the worktable. At least one processing component moves on the crossbeam along the first direction. Each processing component has a cutting tool clamped at its bottom end. The cutting tool moves along a third direction (Z-axis direction) to process the target circuit board carried on the worktable. The first direction, the second direction, and the third direction are perpendicular to each other.

[0028] Specifically, the machining component can be controlled by a corresponding drive mechanism to move relative to the base in a first direction. Simultaneously, the cutting tool of the machining component can move in a third direction under the drive of the corresponding drive mechanism. During this third-direction movement, the cutting tool can machine a workpiece, such as a circuit board, located on the worktable. The movement of the machining component in the first direction adjusts the position of the cutting tool relative to the workpiece in that direction. Typically, for structural simplicity, a drive mechanism capable of moving in a second direction is not installed on the base to move the machining component in the second direction to change the position of the cutting tool relative to the workpiece. The displacement in the second direction is achieved by the worktable; that is, the corresponding drive mechanism can drive the worktable to move in the second direction, thereby adjusting the position of the cutting tool relative to the workpiece in the second direction.

[0029] Furthermore, to improve processing efficiency and uptime, multiple processing units are typically used simultaneously to process a single workstation. However, due to inherent machining and assembly errors in the spindles of each processing unit, center coordinate deviations exist between the spindles of multiple processing units, reducing the machining accuracy when multiple units process a single workpiece simultaneously. Moreover, the spindles are completely fixed after assembly, making adjustment in the second direction difficult; therefore, center coordinate deviations typically exist in the second direction.

[0030] This disclosure provides a circuit board processing device that can adjust the positional deviation of the spindle in a second direction. The circuit board processing device can be a drilling machine, forming machine, drilling and milling machine, or other equipment that needs to process circuit boards. Specifically, the circuit board processing device includes a crossbeam, a processing assembly, and an adjustment assembly. The processing assembly is used to process the workpiece, which is often a circuit board. A inclined guide rail connects the processing assembly and the crossbeam, allowing the processing assembly to slide obliquely relative to the crossbeam along the inclined guide rail. The adjustment assembly is used to adjust the movement distance of the processing assembly along the inclined guide rail.

[0031] Specifically, the processing component is configured to move obliquely along the inclined guide rail under the force of the adjustment component. The oblique movement causes the processing component to form a certain displacement in two directions, so as to calibrate the deviation generated by the processing component in two directions, that is, to eliminate the deviation generated by the processing component in the second direction. This can avoid the deviation generated by the processing component in the second direction due to installation gaps, positional deviations caused by long-term use, or other factors, thereby improving the processing accuracy of the processing component on the workpiece.

[0032] For ease of understanding, please refer to the following: Figures 1 to 4 The specific structure and working principle of the circuit board processing equipment disclosed herein will be described in detail with reference to one embodiment.

[0033] For ease of explanation of the circuit board processing equipment of this disclosure, please refer to... Figure 1 In a three-axis Cartesian coordinate system, the axial direction of the circuit board processing equipment is denoted as the first direction (X-axis direction), the direction perpendicular to the first direction and in the same horizontal plane as the first direction is denoted as the second direction (Y-axis direction), and the direction perpendicular to both the first and second directions is denoted as the third direction (Z-axis direction). In the following descriptions, including subsequent descriptions of the first, second, and third directions of tilting guides, adjustment mechanisms, etc., the terms "first," "second," and "third" directions are consistent with those of the circuit board processing equipment. This naming is merely for the convenience of those skilled in the art to fully understand the content of this disclosure, and this disclosure does not impose any limitations on it.

[0034] refer to Figures 1 to 2 The circuit board processing equipment disclosed herein includes a crossbeam 1, a processing assembly for processing circuit boards, an inclined guide rail 4 connecting the processing assembly and the crossbeam 1, the processing assembly being able to slide obliquely relative to the crossbeam 1 along the inclined guide rail 4, since the inclined guide rail 1 is inclined, the processing assembly will generate displacement in two directions, a second direction and a third direction, when it moves obliquely, so that the processing assembly moves in the third direction to slightly adjust the deviation of the processing assembly in the second direction; and an adjustment assembly, which is located at the lower end of the processing assembly and is used to adjust the distance the processing assembly moves along the inclined guide rail.

[0035] The circuit board processing equipment disclosed herein achieves second-direction calibration of processing components within the equipment. When multiple processing components process the same workpiece, the position of each component in the second direction can be fine-tuned until the positions of all spindles are adjusted within the allowable range of processing errors. Since the calibration of deviations is usually minute, compared to directly setting a calibration mechanism on the processing component that moves only in the second direction, the circuit board processing equipment of this disclosure achieves second-direction calibration by moving simultaneously in the third and second directions. This avoids complicating the structure of the circuit board processing equipment while saving structural and movement space for the calibration mechanism. The inclined guide rail 4 is configured such that the processing component moves obliquely downward or upward relative to the crossbeam 1 in the vertical direction. This allows the adjusting component to drive the processing component to move obliquely along the inclined guide rail 4 while maintaining the first direction unchanged, while generating displacement in the third and second directions. This achieves the purpose of adjusting the deviation of the processing component in the second direction.

[0036] like Figure 1 As shown, the inclined guide rail 4 includes a first slider 41 and a second slider 42, which are connected by an inclined sliding connection. The first slider 41 can slide obliquely relative to the second slider 42. The first slider 41 has an inclined surface, and the second slider 42 also has an inclined surface. The inclined surfaces of the first slider 41 and the second slider 42 match, allowing them to slide relative to each other. To prevent displacement in other directions during the relative sliding of the first slider 41 and the second slider 42, a sliding track and a groove adapted to the sliding track can be provided between the two inclined surfaces. The sliding track and groove not only serve to guide the sliding but also prevent large resistance from being generated during the relative sliding between the sliders, thus improving the stability during the sliding process. Methods to prevent displacement in other directions between the two sliders include not only providing a sliding track and groove on the inclined surface but also installing supports at both ends of one slider, allowing one slider to slide within the support of the other slider, etc. The specific structural limitations on the directional sliding structure between the first slider 41 and the second slider 42 are not specified.

[0037] One end of the inclined guide rail 4, a first slider 41, is connected to the crossbeam 1, and the other end, a second slider 42, is connected to the processing assembly. The inclined movement between the first slider 41 and the second slider 42 causes the processing assembly to tilt relative to the crossbeam 1. The processing assembly includes a base plate 2 and a spindle 3. The base plate 2 remains vertical, and the spindle 3 is configured to move up and down on the base plate 2 to process the circuit board on the worktable below the spindle 3. Specifically, the side of the base plate 2 closest to the crossbeam 1 is connected to the inclined guide rail, while the side of the base plate 2 furthest from the crossbeam 1 is connected to the spindle 3. The second slider 41 is connected to the base plate 2. The inclined movement between the first slider 41 and the second slider 42 is converted into an inclined movement of the base plate 2 along the second and third directions, which in turn is converted into an inclined movement of the spindle 3. This adjusts the positional deviation of the spindle 3 in the second direction. By adjusting the position of each spindle 3 in the second direction, the consistency of the position of all spindles in the second direction can be maintained, reducing processing errors and decreasing the scrap rate.

[0038] refer to Figure 1 In this embodiment, the crossbeam 1 is a crossbeam slider (crossbeam 1) that can move along the crossbeam in a first direction and is mounted above the base. The base plate 2 is connected to the crossbeam 1, and the crossbeam 1 can move along the first direction to adjust the position of the main shaft 3 in the first direction. One end of the crossbeam 1 is connected to the first slider 41, and the side of the base plate 2 near the crossbeam 1 is connected to the second slider 42. Generally, the connection surface between the crossbeam 1 and the first slider 41 is a vertical surface, and the connection surface between the base plate 2 and the second slider 42 is also a vertical surface. When the base plate 2 moves in the third direction Z-axis, it slides obliquely in the direction of the inclined surfaces of the first slider 41 and the second slider 42, converting the vertical movement of the base plate 2 into movement in the second and third directions. Since the connection surfaces of the base plate 2 and the crossbeam 1 with the inclined guide rail 4 are uniformly vertical, while the connection surface between the first slider 41 and the second slider 42 is an inclined surface, the shapes of the first slider 41 and the second slider 42 are similar to triangles, and the inclined surfaces of the two triangular sliders slide against each other.

[0039] However, the structure of the inclined guide rail 4 is not limited to this. For example, the side of the crossbeam 1 closest to the base plate 2 can be set as an inclined surface, and one side of the inclined guide rail 4 can be set to match the inclined surface of the crossbeam 1. The other side of the inclined guide rail 4 is connected to the vertical plane of the base plate 4. The inclined guide rail 4 does not need to be equipped with two sets of separate sliding sliders; only one inclined slider is required. Similarly, the connection surface between the inclined guide rail 4 and the crossbeam 1 is an inclined surface. A sliding guide rail and a groove can be provided between the inclined surfaces, or a baffle can be set on the edge of one of the inclined surfaces of the crossbeam 1 or the inclined surface of the inclined guide rail 4. One of the inclined surfaces slides along the baffle of the other inclined surface to prevent displacement in other directions during the sliding process of the inclined guide rail 4 and the crossbeam 1.

[0040] The adjustment component is located below the base plate 2 and is used to adjust the vertical position of the base plate 2, thereby adjusting its position in the second direction. The tilt angle of the inclined guide rail 4 affects the movement distance of the base plate 2 in the second direction. Under the same adjustment distance conditions, different tilt angles of the inclined guide rail 4 result in different movement distances along the second direction. To accommodate different degrees of deviation between different devices, the inclined guide rail 4 is detachably installed between the base plate 2 and the crossbeam 1. Taking the tilt angle of the inclined guide rail 4 from top to bottom as an example, if the deviation between the processing components is small, a set of inclined guide rails 4 with a smaller tilt angle can be selected, including a first slider 41 and a second slider 42 with compatible inclined surfaces. The first slider 41 and the second slider 42 are respectively connected and fixed to the crossbeam 1 and the base plate 2. When the adjustment component adjusts the position of the base plate 2, the movement distance of the processing components in the second direction can be adjusted more precisely. If the deviation between the processing components is large, a set of inclined guide rails 4 with a larger tilt angle can be selected and installed between the crossbeam 1 and the base plate 2. The adjustment component can adjust a longer distance in the second direction. Different inclined guide rails can be installed according to actual processing needs, making the equipment more adaptable and wider in application. The detachable connection between the inclined guide rails 4 and the crossbeam 1 and the base plate 2 can be a rail connection or other methods, and no specific restrictions are made here.

[0041] The machining assembly also includes a spindle clamp 31, which, together with the pressure cap 7, fixes the spindle 3 to the spindle clamp 31. The spindle clamp 31 is connected to the base plate 2 via a vertical slide rail 6, and can drive the spindle 3 to move up and down on one side of the base plate 2. One side of the base plate 2 is connected to the crossbeam 1 via an inclined guide rail 4, and the other side of the base plate 2 is connected to the spindle clamp 31. After the base plate 2 is adjusted to the second direction position via the inclined guide rail 4, it will not move further. The spindle clamp 31 moves up and down on one side of the base plate 2, driving the spindle 3 to move downward to process the workpiece below the machining spindle 3.

[0042] like Figure 3 As shown, the adjustment assembly includes an adjustment bolt 51 and an adjustment base 52. The adjustment bolt 51 is installed on the adjustment base 52 and can move up and down within the adjustment base 52. The adjustment base 52 is located below the base plate 2. The upper end of the adjustment bolt 51 passes through the adjustment base 52 and abuts against the bottom of the base plate 2. The adjustment bolt 51 is used to move up and down to adjust the position of the base plate 2 in the vertical direction. Figure 4The diagram shows the structure of the adjustment assembly. The adjustment base 52 includes a base support 53 and a base platform 54. The base support 53 supports the base platform 54, forming an operating space below the base platform 54. The adjustment bolt 51 passes through the lower end of the base platform 54 and presses against the upper base plate 2. The adjustment bolt 51 can be adjusted within the operating space below the base platform 54. The adjustment bolt 51 moves up and down inside the base platform 54 to adjust the vertical position of the base plate 2.

[0043] The adjusting bolt 51 passes through the base platform 54 and abuts against the bottom of the base plate 2. The movement of the base plate 2 in the vertical second direction is controlled by the weight of the base plate 2 itself and the lifting force of the adjusting bolt 51, thereby adjusting the position of the main shaft 3 in the second direction. Specifically, the adjusting bolt 51 can be adjusted manually to change its vertical position, thus adjusting the vertical position of the base plate 2. Manual adjustment offers high flexibility, does not occupy mechanical space, and is highly operable. Since the traditional threaded adjustment pitch is too large for this structure, a fine-thread bolt is used in this embodiment to achieve micro-adjustment, thereby reducing the adjustment resolution. Of course, the adjusting mechanism can also be connected to other mechanical structures to control the vertical movement of the adjusting bolt 51; this is not limited here.

[0044] During the up-and-down movement of the adjusting bolt 51, the base plate 2 will move obliquely along the inclined guide rail, resulting in a certain displacement in both the second and third directions. Generally, the deviation of the spindle in the second direction is small, requiring only slight adjustment of the adjusting mechanism. Since the adjusting base 52 is fixed to the worktable, a slight displacement friction will occur between the adjusting bolt 51 and the base plate 2 during adjustment. Due to the small displacement, the friction between the two is generally negligible. To avoid relative displacement friction between the adjusting bolt 51 and the base plate 2, a transverse opening can be provided in the adjusting base 52 along the second direction. That is, during adjustment, the adjusting bolt 51 can move within the transverse opening. The adjusting bolt 51 and the bottom of the base plate 2 are relatively fixed, and no relative displacement occurs between them, thus avoiding friction.

[0045] Furthermore, it also includes a measuring component 8, which is used to measure the distance the processing component moves along the inclined guide rail 4, in order to achieve precise adjustment. Figure 2 and Figure 4As shown, in this embodiment, the measuring component includes a grating ruler 81 and a reading head 82. The grating ruler 81 and the reading head 82 are located on the base plate 2 and the adjusting base 52, respectively. When the base plate 2 moves, it will be displaced relative to the adjusting base 52. At this time, a relative displacement will occur between the grating ruler 81 and the reading head 82. The moving distance of the base plate 2 is calculated based on the reading change caused by the displacement. The measuring component 8 is located at the lower end of the base plate 2. The grating ruler 81 is attached to one side wall of the lower end of the base plate 2 through the grating ruler fixing seat 83, and the reading head 82 is fixed to the base platform 54 through the reading head bracket 84. The positions of the reading head 82 and the grating ruler 81 are exactly corresponding. When the base plate 2 is adjusted and moved, the grating ruler 81 moves with the base plate 2, while the reading head 82 remains stationary. A relative movement occurs between the reading head 82 and the grating ruler 81. By reading the change data of the grating ruler 81, the movement distance of the processing component along the second and third directions is calculated, thereby achieving the precise adjustment function and the purpose of adjusting the position of the spindle 3 in the second direction.

[0046] Furthermore, in order to ensure that the reading head 82 can be stably placed on the base platform 54, a protrusion is provided on the horizontal end face of the base platform 54 where the reading head 82 is placed. The protrusion is used to stably lock the reading head bracket 84 on the base platform 54, so as to prevent the reading head 82 from being displaced and affecting the reading accuracy.

[0047] Furthermore, the movement distance of the main shaft 3 along the second direction is calculated using the reading changes of the grating ruler 81 and the reading head 82. This calculated distance is related to the tilt angle of the inclined guide rail 4. Different tilt angles between different inclined guide rails 4 result in different movement distances of the main shaft 3 along the second direction when the base plate 2 moves the same distance vertically. Taking a 45-degree tilt angle between the first slider 41 and the second slider 42 as an example, the movement distance of the base plate 2 in the third vertical Z-axis direction is the same as its movement distance in the second direction Y-axis direction. The movement distance of the main shaft 3 in the second direction can be determined by the reading on the grating ruler 81. Similarly, the conversion between the movement distance of the main shaft 3 in the Y-axis direction and the distance of the base plate 2 in the Z-axis direction is performed based on the tilt angle of the inclined guide rail. By coordinating the measuring and adjusting components, the screwing direction of the adjusting bolt 51 is manually controlled to precisely adjust the positional deviation of the main shaft 3 in the Y-axis direction.

[0048] By setting an inclined guide rail 4 between the machining component and the crossbeam 1, the machining component can tilt and move relative to the crossbeam 1, generating movement in both the second and third directions. This allows for adjustment of the spindle 3's positional deviation in the second direction during multi-axis machining, maintaining consistency in the positions of all spindles. By setting an adjustment component at the lower end of the machining component's base plate 2 and cooperating with the measuring component, the positional change of the base plate 2 in the third direction is accurately acquired, and the positional change of the spindle 3 in the second direction is calculated, enabling minute adjustments in the spindle's Y-direction.
