Description
Technical Field
The present invention relates to a supporting mechanism, and more particularly to a supporting mechanism for supporting two sides of a substrate. In addition, the invention also relates to a clamping device which is provided with the propping mechanism and can be installed on a conveying device.
Background
In the manufacturing process of the circuit board, after a semi-finished substrate is clamped and fixed by a clamping device carried on a conveying device, the conveying function is achieved through the driving of the conveying device. However, the conventional clamping device is only suitable for clamping a substrate of a single size (e.g., an area of 30cm × 30cm), and for a substrate of another size (e.g., an area of 10cm × 10cm), the entire production line must be replaced with a corresponding clamping device to clamp and fix the substrate, in which case, when the production line is to produce substrates of different sizes, a technician must replace all the clamping devices together to smoothly convey the substrates, which not only increases the production cost, but also wastes labor and time.
For example: taiwan patent No. TW I660655B discloses a PCB frame-clip type bracket and a method for supporting a PCB by using the bracket, which facilitates carrying substrates of different areas by means of the relative reverse swinging function of double clip arms. Due to the many possibilities of the structural design of the mechanical device, there is still room for development to develop different structural designs to provide different usage requirements.
In addition, in a production line of substrates (such as circuit boards), an operator puts the substrates one by one on a conveyor belt, the substrates are conveyed to corresponding processing equipment by the conveyor belt for manufacturing, and corresponding substrate conveying equipment conveys the substrates to perform corresponding manufacturing steps in each processing equipment, wherein one substrate conveying equipment comprises a conveying device and a plurality of clamping devices which are arranged on the conveying device and are adjacent to each other. Each clamping device is driven by the conveying device and can perform clamping (rotating) when reaching a feeding area so as to clamp the substrate, however, the frequency of placing the substrate by an operator is not consistent with the operating frequency of the conveying device, so that the situation that no substrate can be clamped by partial clamping devices occurs, but the whole clamping device is easy to shake in the rotating and clamping process, and further the clamping devices or the substrate clamped by the front and rear adjacent clamping devices collide, and the clamping devices or the substrate is damaged.
Disclosure of Invention
The present invention is directed to a supporting mechanism capable of clamping substrates of different areas to improve the flexibility of use, and further, the supporting mechanism can maintain a positioning state without performing a clamping operation (rotation), thereby preventing the substrate from shaking and ensuring that the substrate does not collide with an adjacent substrate or a clamping device.
The present invention is directed to a clamping device capable of solving the above problems, thereby improving the yield of substrate manufacturing.
The support mechanism is suitable for supporting the side edge of the substrate and comprises a support frame, a movable support rod and a pressurizing assembly. The support frame comprises a frame body and a pivot, wherein the frame body corresponds to the side edge of the base plate, and the pivot penetrates through the frame body. The movable supporting rod comprises a pivoting end part pivoted to the pivot shaft and an abutting end part opposite to the pivoting end part and capable of abutting against the side edge of the base plate, and the abutting end part can move between a first position and a second position which is lower than the first position relative to the support frame. The pressurizing assembly comprises a first shaft rod arranged on the frame body and lower than the pivot, a second shaft rod arranged on the movable support leaning rod and far away from the pin-jointed end part, a connecting piece with one end connected with the first shaft rod and extending to the space between the pin-jointed end part and the second shaft rod, and a pressurizing elastic piece with two opposite ends respectively connected with the connecting piece and the second shaft rod, wherein when the leaning end part faces the substrate direction and passes through the upper part of the support frame, the pressurizing elastic piece automatically moves the leaning end part to the first position or the second position towards the substrate direction and tightly leans against the side edge of the substrate.
In some embodiments, the abutting end portion is movable relative to the supporting frame in a direction away from the substrate to a third position farther from the substrate than the supporting frame, and in the third position, the connecting member abuts against the pivot to overcome the elastic restoring force of the pressing elastic member to position the abutting end portion.
In some embodiments, the pivot has a shaft portion extending through the frame body, two extending portions extending radially outward from two opposite ends of the shaft portion and located in the frame body, and a surrounding groove located between the extending portions and surrounding one side of the shaft portion facing the base plate, wherein when the abutting end portion is driven by the pressing elastic member to move in a direction away from the base plate, the connecting member is inserted into the surrounding groove and abuts against the shaft portion, so that the abutting end portion is positioned.
The clamping device is suitable for clamping two opposite side edges of a substrate and comprises a base and two supporting mechanisms. The supporting mechanisms are respectively arranged on the two opposite side edges of the base corresponding to the substrate, and each supporting mechanism comprises a supporting frame, a movable supporting rod and a pressurizing assembly. The support frame comprises a frame body and a pivot, wherein the frame body corresponds to the side edge of the base plate, and the pivot penetrates through the frame body. The movable supporting rod comprises a pivoting end part pivoted to the pivot shaft and an abutting end part opposite to the pivoting end part and capable of abutting against the side edge of the base plate, and the abutting end part can move between a first position and a second position which is lower than the first position relative to the support frame. The pressurizing assembly comprises a first shaft rod arranged on the frame body and lower than the pivot, a second shaft rod arranged on the movable support leaning rod and far away from the pin-jointed end part, a connecting piece with one end connected with the first shaft rod and extending to the space between the pin-jointed end part and the second shaft rod, and a pressurizing elastic piece with two opposite ends respectively connected with the connecting piece and the second shaft rod, wherein when the leaning end part faces the substrate direction and passes through the upper part of the support frame, the pressurizing elastic piece automatically moves the leaning end part to the first position or the second position towards the substrate direction and tightly leans against the side edge of the substrate.
The invention has the beneficial effects that: the clamping device realizes the effect of clamping substrates with different areas by the rotatable movable supporting and leaning rod, and the movable supporting and leaning rod can tightly clamp the substrates by the pressurizing elastic piece, thereby reducing the production cost and the time cost. In addition, the whole structure is simplified, and the effect of clamping the substrate is achieved only by the arrangement of the positions and the connection relations of the pressurizing elastic pieces and the connecting pieces, so that the whole weight is greatly reduced. In addition, the abutting end part is rotated to the third position, and the movable supporting and abutting rod can be limited from rotating relative to the supporting frame by the elastic restoring force of the pressurizing elastic piece and the supporting force of the connecting piece, so that the swinging caused by the rotation can be avoided, the collision with an adjacent clamping device or a substrate clamped by the clamping device can be further ensured, and the manufacturing yield of the substrate in the manufacturing process can be increased.

Detailed Description
Referring to fig. 1 to 3, an embodiment of a clamping device 1 according to the present invention is adapted to clamp two opposite sides 91 of a substrate 9, wherein the clamping device 1 comprises a base 2 and two supporting mechanisms 3. In the present embodiment, the holding apparatus 1 can be switched between a state of holding a substrate 9 having a large holding area as shown in fig. 1, a state of holding a substrate 9' having a small holding area as shown in fig. 2, and a state of not holding any substrate 9 and keeping it in position as shown in fig. 3.
The base 2 extends, for example, in a length direction D1.
The supporting mechanisms 3 are respectively disposed on the base 2 corresponding to two opposite side edges 91 of the substrate 9, and each supporting mechanism 3 includes a supporting frame 31, a movable supporting rod 32 and a pressing assembly 33. In this embodiment, the supporting mechanisms 3 are respectively screwed to two opposite ends of the base 2 and extend along a height direction D2. Since the supporting mechanisms 3 are symmetrically arranged and have similar structures, a specific structure will be further described with reference to one of the supporting mechanisms 3.
Referring to fig. 4, the supporting frame 31 includes a frame body 311 disposed corresponding to the side edge 91 of the substrate 9, and a pivot 312 penetrating the frame body 311. In this embodiment, the cross section of the frame body 311 is U-shaped, and has a front sidewall 313 and a rear sidewall 314 respectively disposed on two opposite sides of the base 2, and an outer sidewall 315 having two opposite end edges respectively connecting the front sidewall 313 and the rear sidewall 314, and the opening of the frame body 311 faces to another supporting frame 31. The pivot 312 has a shaft portion 316 with two opposite ends respectively passing through the upper end of the front sidewall 313 and the upper end of the rear sidewall 314, two extending portions 317 located in the frame body 311 and respectively extending outward from two opposite ends of the shaft portion 316 in the radial direction, and a surrounding groove 318 located between the extending portions 317 and surrounding the shaft portion 316 toward one side of the substrate 9.
The movable support rod 32 includes a pivot end 322 pivoted to the pivot 312, and an abutting end 321 opposite to the pivot end 322 and capable of abutting against the side 91 of the base plate 9. In the present embodiment, the movable support rod 32 has a front side plate 323 and a rear side plate 324 spaced apart in a width direction D3, an outer side plate 325 having two opposite side edges connecting the front side plate 323 and the rear side plate 324, respectively, and a top plate 326 connecting a top end edge of the front side plate 323, a top end edge of the rear side plate 324 and a top end edge of the outer side plate 325. The abutting end 321 includes the top plate 326, the top end of the front plate 323, the top end of the rear plate 324, and the top end of the outer plate 325, and the pivot end 322 includes the bottom end of the front plate 323, the bottom end of the rear plate 324, and the bottom end of the outer plate 325. The movable support rod 32 defines an accommodating space 327 with an opening facing the substrate 9. The front side plate 323 and the rear side plate 324 are respectively pivoted to opposite ends of the pivot 312, so that the movable supporting rod 32 can rotate relative to the supporting frame 31, and when the abutting end 321 of the movable supporting rod 32 rotates toward the base plate 9, one edge of the top plate 326, which is not connected to the front side plate 323, the rear side plate 324 and the outer side plate 325, can abut against the side edge 91 of the base plate 9.
The pressing assembly 33 includes a first shaft 331 disposed on the frame 311 and having a height lower than the pivot 312, a second shaft 332 disposed on the movable support rod 32 and away from the pivot end 322, a connecting member 333 having one end connected to the first shaft 331 and extending between the pivot end 322 and the second shaft 332, and a pressing elastic member 334 having two opposite ends respectively connected to the connecting member 333 and the second shaft 332. In the present embodiment, two opposite ends of the first shaft 331 respectively penetrate through the front sidewall 313 and the rear sidewall 314 and are lower than the pivot 312. The opposite ends of the second shaft 332 are respectively disposed through the front plate 323 and the rear plate 324 and are located in the middle of the movable support rod 32. The connecting member 333 is, for example, an iron wire, and one end of the connecting member 333 is fastened to the first shaft 331, extends toward the accommodating space 327 of the movable backup rod 32, and passes through the pivot 312 toward one side of the substrate 9. The elastic pressing member 334 is, for example, an extension spring, and is located in the accommodating space 327 and between the second shaft 332 and the pivot end 322, one end of the elastic pressing member 334 is fastened to the second shaft 332, and the other end is fastened to one end of the connecting member 333 extending through the accommodating space 327.
With the above structure, the abutting end 321 can be shifted by the elastic force provided by the elastic member 334 between a first position between the supporting frame 31 and the side 91 of the base plate 9 and a second position lower than the first position with respect to the supporting frame 31, and in addition, the abutting end 321 can pass through the supporting frame 31 from the first position toward a direction away from the base plate 9 to reach a third position outside the supporting frame 31.
Referring to fig. 1 and 5, in a more detailed example, for a substrate 9 with a larger clamping area (e.g., 30cm × 30cm), for one of the supporting mechanisms 3, the pressing elastic element 334 is in a stretched state, so that an end of the pressing elastic element 334 connected to the second shaft 332 can provide an elastic restoring force to the second shaft 332, so that the second shaft 332 drives the movable supporting rod 32 to automatically rotate. When the abutting end 321 is driven by a mechanical device to rotate from the third position toward the substrate 9 and passes through the position right above the supporting frame 31 to the position between the supporting frame 31 and the substrate 9, one end of the pressing elastic member 334 connected to the second shaft 332 provides a component force of the movable abutting rod 32 toward the lower side, so that the abutting end 321 of the movable abutting rod 32 automatically rotates toward the substrate 9 until reaching the first position, i.e., abuts against the side 91 of the substrate 9, in which case the abutting end 321 is pressed against the side 91 of the substrate 9 by the force of the pressing elastic member 334. The other abutting mechanism 3 also operates in the same manner to make the abutting end 321 tightly abut against the side 91 of the substrate 9, so that the substrate 9 is tightly clamped by the two abutting mechanisms 3, and the substrate 9 can be stably transported.
In addition, referring to fig. 2, fig. 4 and fig. 5, taking a substrate 9 '(10 cm × 10cm) with a smaller clamping area as an example, for one of the supporting mechanisms 3, due to the smaller area of the substrate 9', the movable supporting rod 32 will be continuously rotated toward the substrate 9 'by the elastic restoring force of the pressing elastic member 334 automatically until reaching the second position, i.e. against the side 91' of the substrate 9 ', after reaching the first position, in which case the other supporting mechanism 3 will make the abutting end 321 tightly abut against the side 91' of the substrate 9 'by the elastic restoring force of the pressing elastic member 334, and thus the two supporting mechanisms 3 tightly clamp the substrate 9', so that the substrate 9' can be stably conveyed. It should be noted that the movable support rod 32 capable of rotating relative to the support frame 31 can be used to clamp substrates 9 with different areas, so that when a substrate 9 with a larger area is manufactured and a substrate 9' with a smaller area is ready to be transported on the same production line, the clamping device 1 does not need to be replaced, and the original clamping device 1 can be used to continue to perform the clamping and transporting steps, thereby greatly reducing the production cost and saving the time cost for performing the replacement operation of the clamping device 1.
In addition, referring to fig. 7 and 8, when a plurality of holding devices 1 are installed on a conveying device 4, the holding devices 1 are respectively used for holding a plurality of substrates 9 for processing, and the conveying device 4 includes a feeding port 41 for providing the substrates 9 and a discharging port 42 for discharging the substrates 9. The conveying device 4 can drive the clamping device 1 to the material inlet 41 to clamp the substrate 9 to be processed, and after the corresponding process steps, the substrate is moved to the material outlet 42 to send out the processed substrate 9. When one of the clamping devices 1 has reached the material inlet 41 but the substrate 9 to be processed has not reached the material inlet 41, as shown in fig. 3 and 6, for the clamping device 1, the movable support rod 32 is driven by a mechanical device to rotate, for example, from the second position toward a direction away from the substrate 9, and after passing through the right above the supporting frame 31, the abutting end 321 is located outside the supporting frame 31, in which case, the pressing elastic member 334 is also in a stretched state, so that the end of the pressing elastic member 334 connected to the second shaft 332 can provide an elastic restoring force to the second shaft 332, so that the second shaft 332 drives the movable support rod 32 to rotate automatically. Accordingly, the end of the pressing elastic member 334 connected to the second shaft 332 provides a component force of the movable support rod 32 toward the lower direction, so that the abutting end 321 of the movable support rod 32 automatically rotates away from the substrate 9 until reaching the third position. Meanwhile, in the process that the abutting end 321 of the movable supporting rod 32 rotates toward the third position, the pressing elastic member 334 will link the connecting member 333, so that the connecting member 333 approaches toward the pivot 312 and a portion of the connecting member is embedded in the surrounding groove 318, and further abuts against the surface of the shaft portion 316, so that the movable supporting rod 32 cannot rotate relative to the supporting frame 31, and the abutting end 321 is spaced from the substrate 9 by positioning, thereby further ensuring that the clamping device 1 does not shake to knock or scratch the substrate 9 clamped by the front and rear adjacent clamping devices 1 and the clamping device 1, and further improving the manufacturing yield of the substrate 9 in the manufacturing process.
Furthermore, when one of the clamping devices 1 has reached the material inlet 41 and the substrate 9 to be processed has also reached the material inlet 41, as shown in fig. 1 and 5, for the clamping device 1, as the above-mentioned operation manner of driving the movable supporting rod 32 to the first position or the second position, the movable supporting rod 32 is respectively rotated relative to the supporting frame 31, and the abutting end 321 tightly clamps the substrate 9 by the elastic restoring force of the pressing elastic member 334, thereby improving the conveying reliability of the substrate 9.
In summary, the clamping device 1 of the present invention achieves the effect of clamping the substrates 9 with different areas by the rotatable movable supporting rod 32, and the pressing elastic member 334 enables the movable supporting rod 32 to tightly clamp the substrates 9, thereby reducing the production cost and time cost. In addition, the above-mentioned efficacy of holding the substrate 9 is achieved only by the arrangement of the positions and the connection relationship of the pressing elastic members 334 and the connection members 333 by simplifying the overall structure, thereby greatly reducing the overall weight. Furthermore, by rotating the abutting end 321 to the third position and limiting the movable supporting rod 32 from rotating relative to the supporting frame 31 by the elastic restoring force of the pressing elastic member 334 and the supporting force of the connecting member 333, in this case, the shaking caused by the rotation can be avoided, and it is further ensured that the collision with the adjacent clamping device 1 or the substrate 9 clamped by the clamping device 1 is not generated, thereby increasing the manufacturing yield of the substrate 9 in the manufacturing process, and the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
