The conveying modes of the processes are not unified, and it is difficult to realize the continuous transfer between the processes. Meanwhile, in order to avoid the volatilization of the strong corrosive and volatile copper sulfate solution on the etching line into the production workshop, a cover is often arranged on the etching tank, which also makes it difficult to connect the devices of the processes.

[0046] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purposes, the specific embodiments of the present application are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0047] Please refer to Figures 1 to 25The embodiment of the present application provides a multi-process integrated production line, which comprises a continuous line 100, at least one set of track conveying assemblies 200 arranged on the two sides of the continuous line 100, and a plurality of workpiece carriers 2 connected with the track conveying assemblies 200, wherein the track conveying assembly 200 comprises a ring-shaped track 201 and a transmission mechanism arranged outside the ring-shaped track 201 and connected with the ring-shaped track 201, the transmission mechanism comprises a main transmission sprocket 202 and a driven sprocket 203 arranged on the two ends of the ring-shaped track 201, a chain 204 sleeved on the outer periphery of the main transmission sprocket 202 and the driven sprocket 203, and a plurality of sliding connection plates 205 fixedly connected with the chain 204, and the sliding connection plate 205 is slidingly connected with the ring-shaped track 201; the workpiece carrier comprises a horizontal frame 21, at least one through slot 22 formed on the horizontal frame 21 for accommodating workpieces, and a plurality of clamps 5 arranged on the side edges of the through slot 22, the clamp 5 comprises at least one clamping block 51 which can be expanded to the side edge, and the clamping block 51 faces the through slot 22, and the two sides of the horizontal frame 21 are fixedly connected with the sliding connection plates 205; and the continuous line 100 comprises a plurality of processing tanks 6 arranged according to processes and located between the two track conveying assemblies 200, the processing tank 6 comprises an upper tank body 61 for containing processing liquid, and the inlet end and the outlet end of the upper tank body 61 are provided with a carrier passing port 62 for the workpiece carrier 2 to pass through.

[0048] Specifically, as shown in Figure 6 and Figure 7 The carrier passing port 62 is enclosed by an upper partition plate 611 and a lower partition plate 612 arranged on the upper tank body 61 and opposite to each other.

[0049] For the connection mode of the sliding connection plate 205 and the ring-shaped track 201, as shown in Figure 5 The lower end of the sliding connection plate 205 is provided with a vertical connection plate 206, and a pair of sliding wheels 207 opposite to each other are arranged on the vertical connection plate 206 and close to the ring-shaped track 201; and a groove 2011 for the sliding wheels 207 to slide is formed on the upper and lower end faces of the ring-shaped track 201.

[0050] The conveying device of the multi-process integrated production line of the embodiment is composed of one or more track conveying assemblies 200, which are arranged through the continuous line 100. The conveying device adopts a conveying mode of a ring-shaped track 201 cooperating with a chain 204 transmission, which ensures that the workpiece carrier plate can be conveyed stably along the ring-shaped track 201 and avoids the workpiece from falling. A horizontal workpiece carrier plate 2 is arranged on the ring-shaped track, so as to realize the horizontal and linear conveying of the workpiece on the continuous line 100. The conveying mode of the whole continuous line 100 is unified, which is beneficial to improving the compactness of the structure of the continuous line 100. Meanwhile, the continuous line 100 adopts a plurality of processing tanks 6 arranged according to processes. The processing tank 6 is located between two ring-shaped tracks 201, and the carrier plate passing port 62 is arranged at the inlet end and the outlet end of the upper tank body 61, so that the workpiece carrier plate 2 carrying the workpiece can smoothly enter and exit the upper tank body 61. In this way, the conveying mode of each process in the processing of the circuit board or the photovoltaic silicon wafer is unified, which is beneficial to integrating each process together to form an integrated production line. Therefore, the transfer work between processes is avoided, the manual operation is greatly reduced, the water and electricity are saved, and the production efficiency is improved.

[0051] In order to facilitate the connection between the workpiece carrier plate 2 and the track conveying assembly 200 and to enable the workpiece carrier plate 2 to contact the processing liquid in the processing tank 6, in the embodiment, the workpiece carrier plate 2 adopts a specially designed connection structure. As shown in Figure 3 , Figures 8 to 10 , the workpiece carrier plate 2 further includes at least one pair of hanging arms 23 arranged on opposite sides of the horizontal frame 21. One end of the hanging arm 23 is connected to the side of the horizontal frame 21, and the other end of the hanging arm 23 extends upward and is bent outward at the end to form a hanging lug 231. A reverse tapered plug 232 is arranged on the lower end surface of the hanging lug 231. Meanwhile, a plug hole (not shown in the description) is formed on the sliding connection plate 205 for the reverse tapered plug to be inserted. In the embodiment, the workpiece carrier plate 2 is hung on the sliding connection plate 205 of the track conveying assembly 200 by arranging the hanging arms 23 on both sides of the horizontal frame 21, so that the horizontal frame 21 carrying the workpiece can extend into the upper tank body 61 to contact the processing liquid. Meanwhile, the workpiece carrier plate 2 is connected to the sliding connection plate 205 in a reverse tapered plug and plug hole cooperation mode, which can quickly and stably fix the workpiece carrier plate 2 on the track conveying assembly 200 without using screws or other fasteners. The workpiece carrier plate 2 is convenient to take and place on the sliding connection plate 205, which is beneficial to realizing the automatic taking and placing of the workpiece carrier plate 2.

[0052] In order to facilitate the replenishment of the processing liquid in the upper tank body 61, ensure the concentration of the processing liquid, and avoid the loss of the processing liquid through the carrier plate passing port 62, in the embodiment, as shown in Figures 6 to 7 , and Figure 22As shown, the processing tank 6 further comprises a sub-tank 63 arranged below the upper tank body 61, and at least one pumping device 64 is arranged between the upper tank body 61 and the sub-tank 63 for pumping the processing liquid in the sub-tank 63 to the upper tank body 61. In this way, the concentration of the processing liquid in the sub-tank 63 can be adjusted first, and when the concentration of the processing liquid in the upper tank body 61 decreases or the liquid level of the processing liquid in the upper tank body 61 decreases, the processing liquid in the sub-tank 63 can be pumped to the upper tank body 61 by the pumping device 64, and the processing liquid flowing out of the port 62 of the carrier plate can directly flow into the sub-tank 63 below.

[0053] During the processing of the circuit board or photovoltaic silicon wafer, highly corrosive and volatile processing liquid is often used, and the processing liquid needs to be heated during the processing, which can cause the processing liquid to volatilize from the processing tank 6, corrode the equipment, be inhaled by the operator, and cause the equipment to be easily damaged and be harmful to the health of the operator. Therefore, as shown in the embodiment, the processing tank 6 further comprises an upper cover 66 arranged on the upper tank body 61, and a conveying passage 200 is formed between the side wall of the upper cover 66 and the side wall of the upper tank body 61 for the annular track 201, the chain 204, and the sliding connecting plate 205 to pass through, and the conveying passage 67 is in communication with the upper tank body 61. Figures 6 to 7

[0054] In order to timely discharge the corrosive gas and avoid excessive pressure in the processing tank 6 and corrosion of the corrosive gas to the annular track 201, the chain 204, and other easily corroded components, as shown in the embodiment, at least one exhaust hole 68 is arranged on the upper end surface of the upper cover 66, and at least one air inlet hole 69 is arranged on the side wall of the upper cover 66 and close to the lower end of the conveying passage 67, and the exhaust hole 68 and the air inlet hole 69 are respectively connected with an air pump (not shown in the drawings). Figures 6 to 7

[0055] ​​In order to avoid the processing liquid flowing out of the carrier plate through the through port 62 too fast, in the embodiment, a soft barrier (not shown in the drawings) is arranged at the through port 62, one end of the soft barrier being connected with the side wall of the through port 62. Specifically, the soft barrier can be a soft film or a soft brush. In this way, when the workpiece carrier plate 2 passes through the through port 62, the soft barrier can be easily pushed aside and passed through, and after the workpiece carrier plate 2 leaves the through port 62, the soft barrier is reset.

[0056] As shown in Figure 8 With Figure 11 In the embodiment, the horizontal frame 21 is provided with a plurality of first partition strips 211 and a plurality of second partition strips 212, the first partition strips 211 and the second partition strips 212 being arranged alternately and separating the horizontal frame 21 into a plurality of through grooves 22. The workpiece carrier plate 2 of the embodiment is formed with a plurality of through grooves 22 for placing workpieces on the frame 21, and the clamps 5 arranged alternately on the side edges of the through grooves 22 tightly hold the opposite side edges of the workpieces, thereby fixing the workpieces and preventing the workpieces from falling during the conveying process. In addition, the clamps 5 do not block the surface of the workpieces, and thus it is not necessary to leave a process edge on the workpieces, which saves materials and reduces the process of cutting the process edge. The workpiece carrier plate 2 can carry a maximum of the same number of workpieces as the number of the through grooves 22 at one time, and the workpiece carrier plate 2 of the embodiment has the characteristics of simple structure and convenient processing. Specifically, the horizontal frame 21 can be integrally formed by one-time molding of plastic, and the number of the through grooves 22 can be increased or decreased according to production needs. Since the clamping blocks 51 have the function of expansion and contraction, the workpieces with sizes within the expansion and contraction range of the clamping blocks 51 can be fixed, and the workpiece carrier plate 2 can be used for carrying and conveying workpieces of various sizes.

[0057] In the embodiment, the clamps 5 are arranged alternately on the opposite side edges of the through grooves 22, which reduces the amount of the clamps 5 while ensuring that the workpieces are stably fixed on the workpiece carrier plate 2. Specifically, as shown in Figure 11 When the workpiece is placed in the through groove 22a, the clamps 5a arranged alternately tightly hold and fix the workpiece in the through groove 22a.

[0058] Since the side edges of the through grooves 22 are formed by the first partition strips 211 and the second partition strips 212 arranged alternately, and the workpiece carrier plate 2 of the embodiment uses the clamping type fixation for the workpieces, only one set of opposite edges of the workpieces needs to be clamped, and thus the fixation of the workpieces is achieved. Therefore, in order to further reduce the number of the clamps 5 and improve the compactness of the structure of the workpiece carrier plate 2, as shown in Figure 8 With Figure 11As shown, in the embodiment, the second partition strip 212 has a width greater than that of the first partition strip 211, and the clamp 5 is arranged on the second partition strip 212 and the side opposite to the second partition strip 212 of the horizontal frame 21.

[0059] As shown in FIG. Figure 8 With Figure 18 As shown, in the embodiment, the horizontal frame 21 is further provided with a mounting groove 213 for mounting the clamp 5, so that the clamp 5 is conveniently mounted and firmly fixed on the horizontal frame 21. The mounting groove 213 can also make the clamp 5 sink into the horizontal frame 21 as a whole, so that the clamping block 51 does not protrude from the upper surface of the horizontal frame 21, thereby reducing the overall thickness of the workpiece carrier plate 2. After the workpiece is clamped and fixed by the clamping block 51 of the clamp 5, the workpiece is located inside the through groove 22 and is blocked by the side of the through groove 22. When the workpiece carrier plate 2 and the workpiece as a whole are conveyed or processed in each processing procedure, the workpiece can be effectively and stably fixed on the workpiece carrier plate 2.

[0060] As shown in FIG. Figures 12 to 15 As shown, in the embodiment, the clamp 5 further includes a clamp body 52 and a tensioning assembly arranged on the clamp body 52. An active cavity 521 is formed in the clamp body 52 for the tensioning assembly. The tensioning assembly includes a moving block 53 movably arranged in the active cavity 521, a pull rod 54 connected to the moving block 53 and extending out of one end of the active cavity 521, and an elastic member 55 located in the active cavity 521 and sleeved on the outer periphery of the pull rod 54. The clamping block 51 is connected to the moving block 53 and extends out of the other end of the active cavity 521.

[0061] Specifically, when it is necessary to put the workpiece on the workpiece carrier plate 2 or loosen the workpiece, the pull rod 54 is pulled outward, so that the pull rod 54 of the clamp 5 moves outward of the through groove 22, and the moving block 53 and the clamping block 51 as a whole move outward of the through groove 22. The elastic member 55 is compressed during the movement of the moving block 51 and generates an elastic restoring force. At this time, the clamp 5 is in an open state, and the workpiece can be put on the workpiece carrier plate 2 or loosened. When it is necessary to clamp the workpiece, the pull rod 54 is released, and the moving block 53 and the clamping block 51 as a whole move inward of the through groove 22 under the action of the elastic restoring force of the elastic member 55, so that the clamping block 51 abuts against the side of the workpiece. By arranging multiple clamps 5 on the opposite sides or around the through groove 22, a clamping force is generated on the side of the workpiece, so that the workpiece is clamped. In this way, the clamp 5 only contacts the side surface of the workpiece and does not block the surface of the workpiece. Therefore, it is not necessary to reserve a process edge on the workpiece, and the process edge does not need to be cut after processing, thereby reducing the processing procedures of the circuit board and effectively reducing the waste of materials.

[0062] In the processing of circuit boards, the processing of relatively soft FPC circuit boards or photovoltaic circuit boards is often involved. The FPC circuit board is relatively soft and easy to deform, and the photovoltaic circuit board is mainly made of glass and is very thin and easy to break. When the workpiece is relatively soft or easy to break, the force of the clamp 5 on the workpiece is too large, which can easily cause the workpiece to deform or be damaged, and the force of the clamp 5 on the workpiece is too small, which can easily cause the workpiece to fall. Therefore, in order to effectively clamp various workpieces, as shown in Figure 12 In the embodiment, the clamping block 51 has a wedge-shaped gap 511 at one end away from the moving block 53. In this way, when clamping the workpiece, the side edge of the workpiece is clamped into the wedge-shaped gap 511, and the clamp 5 does not need to generate too much force on the workpiece to achieve stable clamping of the workpiece. Moreover, the distance between the two sides of the wedge-shaped gap 511 gradually decreases from the insertion port to the inside, and the workpiece surface is not blocked.

[0063] Specifically, as shown in Figure 13 The moving block 53 has a limiting portion 56 protruding inward at one end close to the pull rod 54 and on opposite sides. When the moving plate 53 moves to the position in contact with the limiting portion 56, the pull rod 54 is stopped, which can better control the movement distance of the moving plate 53 and improve the clamping efficiency. At the same time, it prevents the elastic member 55 from being compressed too much, which reduces the service life of the clamp 5.

[0064] In order to facilitate operation, the pull rod 54 is provided with an operating handle 541 at one end extending out of the movable cavity 521.

[0065] In order to facilitate fixation, a plurality of fixing lugs 522 are uniformly arranged on the clamp body 52, and fixing screw holes 5221 are formed in the fixing lugs 522.

[0066] In the embodiment, the elastic member 55 is a spring.

[0067] In order to further improve the automation of the multi-process integrated production line, in the embodiment, as shown in Figure 1 , Figures 16 to 17As shown, the multi-process integrated production line also includes an automatic feeder 300 disposed at the feeding end of the continuous line 100. The automatic feeder 300 includes a feeder frame 1, on which a feeding station and a plate-loading station are disposed. The automatic feeder 300 also includes a clamping mechanism 3 disposed on the feeder frame 1 and located above the plate-loading station, and a feeding assembly 4 disposed on the feeder frame 1 and located below the plate-loading station. The feeding assembly includes a feeding plate 41 and a feeding component 4. A feeding lifting drive mechanism 42 and a feeding horizontal drive mechanism 43 connected to the feeding lifting drive mechanism 42 are provided. The feeding horizontal drive mechanism 43 pushes the feeding plate 41 to move between the feeding station and the upper plate station. The feeding lifting drive mechanism 42 drives the feeding plate 41 to move in the vertical direction. The workpiece carrier plate 2 is set on the upper plate station. Several placement platforms 44 corresponding to the through slots 22 are provided on the feeding plate 41. The placement platforms 44 protrude from the upper surface of the feeding plate 41.

[0068] The automatic feeder 300 of this embodiment is configured with an upper plate station for placing the workpiece carrier plate 2 and a feed plate 41 for placing the feed plate. Several through slots 22 for accommodating workpieces and clamps 5 for fixing workpieces are respectively provided on the workpiece carrier plate 2. Simultaneously, a raised placement platform 44 is provided on the feed plate 41. The horizontal feeding drive mechanism 43 moves the feed plate 41, on which the workpieces are placed, horizontally to below the workpiece carrier plate 2. At this time, the clamping mechanism 3 acts on the clamps 5, causing the clamping blocks 51 on the clamps 5 to move outward from the through slots 22. Then, the lifting feeding drive mechanism 43 drives the feed plate 41 to rise to the position of the workpiece carrier plate 2, so that the feed plate 41... The placement platform 44 extends into the corresponding through slot 22. Then, the clamping mechanism 3 releases the force on the clamp 5. Under the elastic restoring force of the elastic element 55, the clamping block 51 on the clamp 5 moves inward to the inside of the through slot 22 and acts on the side of the workpiece to fix it. Finally, the loading lifting drive mechanism 42 drives the loading plate 41 to descend, and the loading horizontal drive mechanism 43 drives the loading plate 41 to move to the loading station 11. At the same time, when the loading plate 41 is completely separated from the workpiece carrier plate 2, the workpiece carrier plate 2 carrying the workpiece can be moved as a whole to the continuous line 100. In this way, the loading of multiple workpieces can be completed at one time, which greatly improves the efficiency of workpiece loading.

[0069] like Figure 17 As shown, in order to avoid the clamp 5 from clamping the placement table 44, in this embodiment, the distance between the two opposite sides of the placement table 44 is less than the distance between the corresponding two sides of the workpiece 6. In this way, when the workpiece 6 is placed on the placement table 44, the opposite sides of the workpiece 6 extend out of the placement table 44, and the clamp 5 will not contact the sides of the placement table 44 when clamping the workpiece, thus successfully clamping the workpiece 6.

[0070] In order to avoid the workpiece from being displaced due to the shaking of the feeding plate 2 during the moving process, and the workpiece cannot be smoothly sent to the corresponding through slot 22, as shown in Figure 20 With Figure 21 In the embodiment, a plurality of vacuum adsorption holes 441 are arranged on the placing table 44. The vacuum adsorption holes 441 are connected with the vacuumizing equipment. During the moving process, the vacuum adsorption holes 441 are in the vacuum state, so that the workpiece is firmly attached to the placing table 44. When the workpiece is sent to the workpiece carrier plate 2 and clamped by the clamp 5, the vacuumizing is stopped, and the vacuum adsorption holes 441 no longer have the adsorption force on the workpiece, so that the clamp 5 can smoothly clamp the workpiece.

[0071] As shown in Figure 16 , Figure 17 With Figure 19 In the embodiment, the opening and clamping mechanism 3 comprises an opening and clamping lifting drive motor 31, an opening and clamping connecting plate 32 arranged on the output shaft of the opening and clamping lifting drive motor 31, and a plurality of pins 33 arranged on the lower end surface of the opening and clamping connecting plate 32 and corresponding to the clamps 5. The pins 33 are opposite to the positions between the operating handles 541 and the clamp bodies 52. The lower end of the pin 33 has a guide slope 331. In this way, when the clamp needs to be opened, the opening and clamping lifting drive motor 31 drives the opening and clamping connecting plate 32 to descend, and drives the pins 33 to move downward. When the lower end of the pin 33 is inserted between the operating handle 541 and the clamp body 52, the operating handle 541 gradually moves outward of the through slot 22 under the action of the pin 33, and drives the moving plate 53 and the clamp block 51 to move outward of the through slot 22 as a whole, until the clamp block 51 completely leaves the through slot 22, and the opening and clamping is completed. At this time, the elastic member is compressed to generate elastic restoring force. Then, the servo motor of the feeding lifting drive mechanism 4 drives the feeding plate 41 to ascend, drives the placing table 44 to ascend and extend into the through slot 22, so that the workpiece and the clamp block 51 of the clamp 5 are on the same horizontal plane. When the workpiece needs to be clamped, the opening and clamping lifting drive motor 31 drives the opening and clamping connecting plate 32 to ascend, and drives the pin 33 to move upward. The pin 33 no longer acts on the operating handle 541 of the pull rod 54. The pull rod 54 gradually moves into the through slot 22 under the action of the elastic restoring force of the elastic body 55, and drives the moving plate 53 and the clamp block 51 to move into the through slot 22 as a whole, until the clamp block 51 contacts the side edge of the workpiece and clamps it. The opening and clamping mechanism 3 of the embodiment can simultaneously control the clamp blocks 51 in all clamps 5 on the workpiece carrier plate 2 to extend and retract on the side edge of the through slot 22, so that the clamps clamp or release the workpiece, and greatly improve the clamping efficiency of the workpiece carrier plate 2 on the workpiece.
