Description

Technical Field

[0001] The utility model relates to the technical field of circuit board forming, in particular to a circuit board forming machine. Background Art

[0002] In the circuit board processing industry, traditional PCB multi-axis forming machines can only use a single system to process products of the same material number at the same time, and cannot realize the simultaneous processing of multiple products. In order to improve the processing efficiency, flexibility and reduce costs of machine tools, independent processing forming machines have been introduced, that is, two independent control systems are installed on the original crossbeam. During processing, you can freely choose to start any system alone or start both systems at the same time to process the workpiece, meet the needs of small batch production, and meet the needs of processing workpieces of different specifications at the same time.

[0003] However, both control systems require debugging accuracy when they are installed. Since the two control systems are installed on the same beam, there is mutual interference between them, so the debugging process is more complicated and the assembly is more difficult, which reduces the processing efficiency. And during processing, the moving bodies of the two control systems also interfere with each other, which seriously reduces the processing accuracy and affects the product yield.

[0047] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] See also Figures 1 to 10 As shown, an embodiment of the utility model provides a circuit board forming machine, which includes a frame structure, a processing device and a bearing device. The frame structure 100 includes a crossbeam, a base and a machine tool 160. The crossbeam includes a first crossbeam 110 and a second crossbeam 120 arranged at intervals. The first crossbeam 110 and the second crossbeam 120 are arranged at intervals from the machine tool 160. The base is connected between the first crossbeam 110 and the machine tool 160 and between the second crossbeam 120 and the machine tool 160. The processing device includes a first processing device 200 and a second processing device 300 arranged at intervals. The first processing device 200 is movably connected to the first crossbeam 110, and the second processing device 300 is movably connected to the second crossbeam 120. The machine tool 160 has a first processing area and a second processing area. The first processing device 200 is arranged corresponding to the first processing area, and the second processing device 300 is arranged corresponding to the second processing area. The carrying device includes a first carrying device 400 and a second carrying device 500 both movably connected to the machine tool 160 . The first carrying device 400 can be moved to a first processing area, and the second carrying device 500 can be moved to a second processing area.

[0049] It can be understood that the frame structure 100 may include multiple beams, multiple processing devices, and multiple processing areas. The multiple beams, multiple processing devices, and multiple processing areas are correspondingly arranged, which is not limited here.

[0050] In the circuit board forming machine 10 of this embodiment, by setting at least two beams corresponding to at least two processing devices, it is possible to avoid the influence of the processing devices on each other when they move. At the same time, by dividing the longer beam into the first beam 110 and the second beam 120, it is helpful to reduce the influence of thermal expansion and contraction on the long-span beam, and the processing accuracy is improved. The overall structure of the circuit board forming machine 10 is compact. During operation, when part of the beams need maintenance, compared with the traditional single long-span beam, the circuit board forming machine 10 of this embodiment can replace a single beam, and the convenience of assembly and maintenance is improved. The base is connected between the first beam 110 and the machine tool 160 and between the second beam 120 and the machine tool 160, thereby increasing the overall strength of the frame structure 100.

[0051] Specifically, the machine tool 160 has a first direction, and the first beam 110 and the second beam 120 both extend along the first direction and are arranged side by side along the first direction. Figure 1 As shown, the length direction of the circuit board forming machine 10 shown in the drawings is the first direction, that is, the X direction in the drawings.

[0052] In actual applications, since there are many loads on the beam, such as processing devices and other structures, when the beam is too long, it is easy to be deformed by force. At the same time, in a high temperature environment, the beam will also be affected by the temperature and expand and deform. These deformations will change the position and angle of the beam, thereby affecting the processing accuracy of the machine. Accuracy errors exceeding the standard will lead to a decrease in the quality of the processed product, and even make the entire processing process invalid. Therefore, this embodiment improves the structural strength of the beam while reducing the influence of temperature expansion and contraction on the beam by dividing the longer beam into at least a shorter first beam 110 and a second beam 120. The assembly and debugging of the first beam 110 and the second beam 120 do not interfere with each other, which reduces the difficulty of installation and debugging, and also reduces the cost of subsequent maintenance of the circuit board forming machine 10. And when the circuit board forming machine 10 is processing and running, each system will not affect each other or the impact is small, which is conducive to ensuring the processing accuracy.

[0053] In one embodiment, the base includes a first base 130, a second base 140 and a third base 150, and the two ends of the first beam 110 are respectively connected to the first base 130 and the third base 150 and are enclosed to form a first avoidance space, and the first supporting device 400 can move in the first avoidance space, and the two ends of the second beam 120 are respectively connected to the second base 140 and the third base 150 and are enclosed to form a second avoidance space, and the second supporting device 500 can move in the second avoidance space.

[0054] In another embodiment, the base includes a first base 130, a second base 140, a third base 150 and a fourth base. The first base 130 and the third base 150 are respectively connected to the two ends of the first beam 110 and are surrounded to form a first avoidance space. The first supporting device 400 can move in the first avoidance space. The two ends of the second beam 120 are respectively connected to the second base 140 and the fourth base and are surrounded to form a second avoidance space. The second supporting device 500 can move in the second avoidance space.

[0055] See also Figure 2 As shown, the machine tool 160 includes a bed 161 and a plurality of transverse ribs, a base is arranged on the top of the bed 161, a plurality of transverse ribs are arranged in parallel and at intervals and connected to the bed 161, and the transverse ribs are arranged at the bottom of the bed 161. By arranging a plurality of transverse ribs connected to the bed 161, the overall mode of the frame structure 100 can be improved, and while ensuring the overall structural strength, the weight of the bed 161 can be reduced accordingly to achieve cost reduction. It should be noted that the top of the bed 161 refers to the upper end of the bed 161 in the vertical direction, and the bottom of the bed 161 refers to the lower end of the bed 161 in the vertical direction.

[0056] In one embodiment, the transverse ribs include a first transverse rib 162 and a second transverse rib 163, both of which extend along the first direction, and the second transverse rib 163 is arranged corresponding to the first crossbeam 110 and the second crossbeam 120, and the first transverse rib 162 is located on one side of the second transverse rib 163; the area of ​​the cross section of the second transverse rib 163 perpendicular to the first direction is greater than the area of ​​the cross section of the first transverse rib 162 perpendicular to the first direction.

[0057] In this embodiment, the machine tool 160 is a double transverse rib structure, the width of the transverse rib is slightly lower than the width of the bed 161, and the cross-sectional area of ​​the first transverse rib 162 is smaller than the second transverse rib 163, and the span of the auxiliary supports on both sides of the first transverse rib 162 is larger than the second transverse rib 163, which is convenient for workshop assembly and reduces deformation of the bed 161. It should be noted that the cross section here refers to, for example, Figure 2 In the placement state, a plane is taken, which is perpendicular to the extension direction of the first transverse rib 162 (i.e., the X direction in the figure). At this time, after the plane intersects with the first transverse rib 162, the projection of the first transverse rib 162 on the plane is the cross section of the first transverse rib 162, and the cross section of the second transverse rib 163 is the same. In a preferred embodiment, since the second transverse rib 163 and the crossbeam are respectively arranged on opposite sides of the bed 161 and are arranged oppositely, the cross-sectional area of ​​the second transverse rib 163 can be increased to improve its own strength, thereby enhancing the bearing capacity.

[0058] Specifically, see Figure 2As shown, the first transverse rib 162 and the second transverse rib 163 are sequentially arranged in the second direction, that is, along the Y direction in the figure, and the first direction is perpendicular to the second direction.

[0059] Furthermore, the end of the first transverse rib 162 away from the bed 161 and the end of the second transverse rib 163 away from the bed 161 both have multiple support positions 164, the distance between two adjacent support positions 164 on the first transverse rib 162 is a first distance, and the distance between two adjacent support positions 164 on the second transverse rib 163 is a second distance, and the second distance is less than or equal to the first distance.

[0060] It can be understood that since the second transverse rib 163 is arranged opposite to the crossbeam, the load-bearing capacity of the second transverse rib 163 is greater than that of the first transverse rib 162. By setting the second distance to be less than or equal to the first distance, the load-bearing capacity thereof can be improved by increasing the density of the support positions 164 on the second transverse rib 163.

[0061] In some embodiments, the first processing device 200 includes a beam driving assembly 210, a motion assembly 220, and a plurality of first spindles 230. The beam driving assembly 210 is connected to the beam, one end of the motion assembly 220 is connected to the beam driving assembly 210, and the other end is connected to the plurality of first spindles 230. In this embodiment, the beam driving assembly 210 is used to drive the first spindles 230 to move laterally, and the motion assembly 220 is used to drive the first spindles 230 to move up and down, thereby controlling the spindles 230 to perform processing actions.

[0062] Specifically, see Figure 4 and Figure 5 As shown, the motion component 220 includes a Z-axis base plate 221, a fixed plate 222 and a Z-axis driving mechanism 223. The Z-axis base plate 221 is movably connected to the beam driving component 210 and is connected to the beam. One end of the fixed plate 222 is movably connected to the Z-axis base plate 221, and the other end is connected to a plurality of first spindles 230. The Z-axis driving mechanism 223 is fixed to the Z-axis base plate 221, and the output end of the Z-axis driving mechanism 223 is connected to the fixed plate 222. The Z-axis driving mechanism 223 can drive the fixed plate 222 to move relative to the Z-axis base plate 221, thereby driving the plurality of first spindles 230 fixed on the fixed plate 222 to move simultaneously.

[0063] With this arrangement, the Z-axis base plate 221 is driven to move relative to the crossbeam by the crossbeam driving assembly 210, and the Z-axis driving mechanism 223 can drive the fixing plate 222 to move vertically, so as to drive the first spindle 230 to move toward or away from the circuit board on the supporting device.

[0064] In a preferred embodiment, the beam drive assembly 210 is also preferably a screw servo drive structure, and the two groups of beam drive assemblies 210 are respectively connected to their respective motion assemblies 220, thereby avoiding interference during the operation of the first spindles 230 on the respective processing devices, and at the same time reducing the overall length of the frame structure 100.

[0065] In one embodiment, the fixed plate 222 is provided with an avoidance groove 2221, and the Z-axis driving mechanism 223 includes a Z-axis motor 2231, a Z-axis screw rod 2232 and a Z-axis nut seat 2233, the Z-axis motor 2231 is arranged on the Z-axis base plate 221, the Z-axis screw rod 2232 is connected to the output end of the Z-axis motor 2231, and is transmission-connected to the Z-axis nut seat 2233; the Z-axis nut seat 2233 includes a transmission part 22331 and at least two connecting parts 22332, the transmission part 22331 is located in the avoidance groove 2221, and the at least two connecting parts 22332 are respectively connected to the opposite ends of the transmission part 22331, and are fixed to the opposite sides of the avoidance groove 2221.

[0066] In this embodiment, the Z-axis nut seat 2233 is fixed on opposite sides of the avoidance groove 2221, thereby improving the rigidity of the fixed plate 222. By starting the Z-axis motor 2231 to drive the Z-axis screw rod 2232 to rotate, at this time, since the Z-axis screw rod 2232 is in transmission connection with the Z-axis nut seat 2233, the fixed plate 222 can be driven to move up and down relative to the Z-axis bottom plate 221, and the first spindle 230 can be driven to move. Specifically, the transmission part 22331 is suspended in the avoidance groove 2221 and is transmitted with the Z-axis screw rod 2232. At this time, since the connecting part 22332 is located on both sides of the avoidance groove and connected to the fixed plate 222, not only can the combined structure of the Z-axis nut seat 2233 and the fixed plate 222 be made compact, but also the connection strength of the Z-axis nut seat 2233 can be improved.

[0067] In some embodiments, the motion assembly 220 further includes a balancing cylinder 224 and a balancing adapter plate 225, wherein the balancing cylinder 224 is connected to the Z-axis base plate 221, and one end of the balancing adapter plate 225 is connected to the output end of the balancing cylinder 224, and the other end is connected to the fixed plate 222. The balancing cylinder 224 is used to balance the force applied to the adapter plate 225 during movement, so that the adapter plate 225 moves smoothly and improves the movement stability of the balancing adapter plate 225.

[0068] See also Figure 4 In the embodiment shown, there are two groups of balancing cylinders 224, which are respectively arranged on both sides of the Z-axis drive mechanism 223. In a preferred embodiment, the two groups of balancing cylinders 224 are symmetrically arranged about the Z-axis drive mechanism 223 to balance the forces applied to the adapter plate 225 when it moves. Of course, in other embodiments, more than two groups of motion components 220 may be arranged, which is not limited here.

[0069] Specifically, the second processing device 300 includes a plurality of second spindles 310, and the number of the second spindles 310 is the same as or different from the number of the first spindles 230. It should be noted that the second processing device 300 and the first processing device 200 may also adopt the same or different structures, which is specifically determined according to the actual processing requirements of the circuit board forming machine 10 and is not limited here.

[0070] Specifically, the motion assembly 220 further includes a Z-axis guide rail 226, and the fixed plate 222 is slidably connected to the Z-axis base plate 221 via the Z-axis guide rail 226. It can be understood that by connecting the Z-axis base plate 221 and the fixed plate 222 with the Z-axis guide rail 226, the relative movement of the two can be guided, and the smoothness of the movement of the Z-axis base plate 221 can be improved.

[0071] See also Figure 6 As shown, in one embodiment, the first carrying device 400 includes a carrying platform 410, a plurality of platform support blocks 420 and a carrying drive assembly, one end of the plurality of platform support blocks 420 is movably connected to the machine tool 160, and the other end is fixed to the carrying platform 410, the carrying platform 410 and the machine tool 160 are spaced apart and enclosed to form a accommodating space, the platform support blocks 420 and the carrying drive assembly are both located in the accommodating space, and the carrying drive assembly is connected to the machine tool 160 and is used to drive the carrying platform 410 to move relative to the machine tool 160.

[0072] In this embodiment, by connecting the platform support block 420 between the carrying platform 410 and the machine tool 160 , more space can be reserved for the carrying drive assembly, while avoiding grooving of the bed 161 to improve the rigidity of the bed 161 .

[0073] Specifically, see Figures 7 to 10 As shown, the first supporting device 400 also includes a material lifting assembly 430, which includes a supporting plate 431, a material lifting mechanism 432 and a material lifting guide shaft 433. The supporting plate 431 is used to support the circuit board, and the supporting plate 431 is spaced apart from the supporting platform 410 and is located on the top of the supporting platform 410. The material lifting mechanism 432 is disposed between the material supporting plate 431 and the platform assembly, the material lifting guide shaft 433 is connected to the material supporting plate 431, and the material lifting mechanism 432 is slidably connected to the material lifting guide shaft 433.

[0074] The circuit board is placed on the receiving plate 431 to be processed. After the processing is completed, the ejection mechanism 432 is activated to move relative to the receiving plate 431. At this time, the ejection guide shaft 433 and the ejection mechanism 432 can slide and cooperate to guide its movement. When the ejection mechanism 432 protrudes from the top of the receiving plate 431, it can lift the circuit board to make the circuit board separate from the receiving plate.

At this time, the contour block 43421 is used to support the material receiving plate 431 so that the material receiving plate 431 and the supporting platform 410 are spaced apart, and the height difference between the supporting platform 410 and the material receiving plate 431 can be adjusted by replacing or adjusting the contour block 43421. When the contour block 43421 is a flexible contour block 43421, a buffering function can also be achieved.

[0077] In some embodiments, the lifting material assembly 430 further includes a lifting material buffer 435 and / or a lifting material sensor 436.
