Description

Technical Field

[0001] The invention relates to the technical field of production, and in particular to a production line. Background Art

[0002] In factory production, it is very common to use several parallel and continuously arranged fixtures to clamp workpieces to run on the production line.

[0003] In the existing electroplating production line, the conveyor belt extends horizontally from the initial end of the electroplating to the end where the electroplating is completed. A number of clamps are fixed on the bottom edge of the conveyor belt at intervals. The conveyor belt itself is arranged in a ring shape. A driving part is respectively arranged at both ends of the conveyor belt. Two straight sections are arranged between the two driving parts. The substrate to be electroplated is fixed on a straight section of the conveyor belt by the clamp and moves with the conveyor belt. In the prior art driven production line, since the width of the electroplating section itself is relatively large, if the electroplating section is arranged under both straight sections of the conveyor belt, the space occupied by the entire equipment will be too large, which is not conducive to the construction of the factory and the control of the production process. Therefore, the electroplating section can only be arranged under one straight section.

[0004] However, since the substrate to be electroplated is in a flat plate shape and needs to be transferred in the driving part, the flat plate-shaped substrate to be electroplated will not be able to pass through the driving part smoothly. At this time, the substrate to be electroplated needs to be removed from the transmission belt. Therefore, only one side of the conveyor belt has a straight portion corresponding to the electroplating tank body. In the traditional production line, the substrate will be unclamped and disengaged at the turning point of the conveyor belt after passing through the electroplating tank. During the entire electroplating process, the straight portion on one side of the conveyor belt clamps the substrate for electroplating, while the straight portion on the other side runs without clamping. The force on the unilateral suspension is unbalanced. Therefore, the transmission process cannot ensure that the substrate remains in a vertical state continuously. When the substrate is tilted, it is easy to cause a stuck board phenomenon. At the same time, when the substrate is tilted, it is affected by the weight of the substrate itself, and the hanger is prone to tooth jumping failure, resulting in unstable operation. In addition, the unilateral suspension is concentratedly subjected to the entire gravity of the substrate and the hanger. Long-term operation is likely to cause wear of the unilateral guide structure, affecting its service life. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the hangers in the existing electroplating production line are subjected to unbalanced force during operation, causing faults such as card jamming and tooth jumping, which affects the electroplating quality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0125] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0126] Example 1

[0127] This embodiment provides a production line, such as Figure 1 As shown, it includes a frame 1, a hanger conveying system continuously mounted on the frame in a ring shape, and a plurality of hangers 3 arranged on the hanger conveying system and driven to run intermittently or continuously. The frame 1 is a gantry-type structure and a plurality of hangers 3 are arranged at intervals along the running path of the hangers 3. The hanger conveying system is provided with a plurality of working sections, such as Figure 1As shown, the running direction of the hanger 3 is counterclockwise, and the running path of the hanger 3 includes: loading section A, pre-processing section B, electroplating section C, post-processing section D, unloading section E and hanger temporary storage section F. Specifically, in this embodiment, along the running direction of the hanger 3, the hanger temporary storage section F includes hanger storage position and transfer position in sequence; the loading section A includes hanger adjustment position E2, loading position and loading confirmation position in sequence; the pre-processing section B includes cleaning tank, water washing position D1 and pre-preg position in sequence; the unloading section E includes unloading position E1, hanger adjustment position E2, stripping position E3, water washing position D1 and drying position in sequence, multiple water washing positions D1 are set in the post-processing section D, and multiple continuous electroplating tanks are set in the electroplating section C.

[0128] At least two transfer sections G are also provided in the hanger conveying system. The transfer sections G are respectively provided at the turning points of the circular path formed by the hanger conveying system for conveying the hanger 3. The transfer sections G can be provided between any two adjacent working sections, so as to facilitate the hanger 3 to be transferred from the current running direction to the working section located in another running direction. In this embodiment, the pre-processing section B, the electroplating section C and the post-processing section D are provided on the same running path, and the unloading section E, the hanger temporary storage section F and the loading section A are provided on another running path. The two running paths are provided in parallel and are both linear paths. Therefore, the hanger conveying system in this embodiment forms two turning points, which are respectively located at the two ends of the two parallel linear paths. Accordingly, two transfer sections G are provided, that is, along the running path of the hanger 3, one of which is provided between the loading section A and the pre-processing section B, that is, between the loading confirmation position and the cleaning tank; the other transfer section G is provided between the post-processing section D and the unloading section E, that is, between the water washing position D1 and the unloading position E1 of the post-processing section D, such as Figure 2 As shown, the transfer hanging position between the post-processing section D and the unloading section E is indicated.

[0129] In this embodiment, Figure 4 As shown, between the two transfer hanging sections G, all the working sections on the side where the electroplating section C is located are set at the same height and are all located at a low position, and all the working sections on the other side are set at the same height and are all located at a high position. The height difference in the vertical direction of the staggered heights on both sides is greater than the overall height of the hanger 3 after hanging the workpiece to be processed, so that the hanger 3 can be translated from the high-position side to above the working section on the low-position side when hanging the workpiece to be processed, so as to facilitate the direct transfer of the hanger 3 and the workpiece to be processed.

[0130] Of course, the hanger conveying system can also be formed into a circular path similar to a triangle, in which case the circular path has three turns, and accordingly, three transfer sections G are set; it can also be formed into a circular path similar to a square, and accordingly, four transfer sections G are set at the corresponding turns, etc., depending on specific needs.

[0131] In this embodiment, the hanger conveying system includes guide parts arranged in parallel on both sides of the running path of the hanger 3, and the guide parts on both sides form a double-sided bridge structure. The hanger 3 includes a hanger and matching parts arranged on both sides of the hanger. The matching parts include a first matching part 31, a second matching part 32 and a third matching part 33, wherein the first matching part 31 and the third matching part 33 are symmetrically arranged on both sides of the hanger, and do not interfere with each other during operation. The second matching part 32 is arranged on the same side of the hanger and symmetrically arranged about the center line of the hanger in the vertical direction. In this embodiment, the hanger is a metal hanger plate 30 with a square shape as a whole. A lifting part 34 is arranged on the top of the hanger plate 30 for grabbing and transferring the hanger plate 30. It is straddled on the double-sided bridge structure through the matching part, and can run in the working section in sequence along the guide part of the double-sided bridge structure.

[0132] The guide part includes a first guide component and a second guide component, the second guide component is located in the electroplating section C, and the first guide component is arranged in the remaining working sections. Figure 5 As shown, the second guide assembly includes two circulating transmission devices 2, and the hanger 3 is located between the two circulating transmission devices 2. Two sets of third matching parts 33 are correspondingly and linkedly arranged on the circulating transmission devices 2. A double-sided bridge structure is formed by the two circulating transmission devices 2, and the hanger 3 is bridged on the double-sided bridge structure. The hanger 3 is driven to run by the two circulating transmission devices 2, so that the forces on both sides of the hanger 3 are balanced, and the operation is more stable. At the same time, the unilateral force concentration of a single circulating transmission device 2 is avoided, thereby improving its service life.

[0133] like Figure 5 As shown ( Figure 5 Only part of the line structure is shown between the two end frames for schematic diagram), two circulating transmission devices 2 are arranged in the horizontal direction, and are arranged on the frames 1 at the two ends of the line in a closed loop and rotate synchronously. Figure 6As shown, any one of the circulating transmission devices 2 includes a transmission steel belt 21, a second driver 22 and a transmission shaft 23. The transmission steel belt 21 includes two linear transmission parts 211 and a curved transmission part 212 connecting the corresponding ends of the two linear transmission parts 211. The curved transmission parts 212 at both ends are correspondingly tensioned and wound on the transmission shaft 23 located on the two side frames 1. In this embodiment, the transmission shafts 23 of the two circulating transmission devices 2 are both extended in the vertical direction, and the transmission directions of the linear transmission parts 211 of the two transmission steel belts 21 are parallel to each other. In this embodiment, the second driver 22 uses a motor, and the motor simultaneously drives the two transmission shafts 23 corresponding to the two transmission steel belts 21 located on the same frame 1, so that the two transmission shafts 23 rotate synchronously and in opposite directions. For example, a gear is fixed on each of the two transmission shafts 23, and the two gears are meshed with each other. When the motor drives one of the transmission shafts 23 to rotate clockwise, the gear simultaneously drives the other transmission shaft 23 to rotate counterclockwise. At this time, the two adjacent linear transmission parts 211 in the two transmission steel belts 21 run linearly in the same direction.

[0134] like Figure 8 As shown, two groups of third matching parts 33 are respectively arranged on both sides of the hanging plate 30, and the third matching parts 33 are suitable for being correspondingly and linkedly arranged on two adjacent linear transmission parts 211 in the two transmission steel belts 21. Any third matching part 33 includes a connecting plate 331 and a first support frame 332. In this embodiment, the first support frame 332 is a frame structure as a whole, and the two first support frames 332 are symmetrically fixed on both sides of the hanging plate 30, and the connecting plate 331 is straddled in the frame structure of the first support frame 332. The first support frame 332 is a metal plate, and the plate surface of the metal plate is arranged parallel to the plate surface of the hanging plate 30. During operation, the metal plate is suitable for sliding against the conductive brushes on both sides of the electroplating tank to transfer the current to the clamp 36 under the hanger 3 and to the workpiece to be processed at the same time. The hanger 3 and the transmission steel belt 21 are linked by a chimeric structure. In this embodiment, the chimeric structure adopts a tooth meshing structure, and the tooth meshing structure includes a plurality of belt teeth 210 and a plurality of tooth grooves 3330, as shown in FIG. Figure 8 As shown, a connecting block 333 is respectively provided at both ends of the bottom of each connecting plate 331. Fig.10As shown, a plurality of tooth grooves 3330 are evenly provided at the bottom of each connection block 333, and correspondingly, a plurality of belt teeth 210 matching with the tooth grooves 3330 are provided at the top of the transmission steel belt 21. The belt teeth 210 and the tooth grooves 3330 are meshed with each other to keep the hanger 3 and the transmission steel belt 21 from relative displacement and stable operation. Of course, belt teeth 210 can also be provided on the connection block 333, and matching tooth grooves 3330 can be provided on the top of the transmission steel belt 21, depending on specific needs. The arrangement of the belt teeth 210 and the tooth grooves 3330 can effectively improve the positioning accuracy of the hanger 3 on the transmission steel belt 21. Under the premise of ensuring relative fixation, the smaller the continuously arranged belt teeth 210 are, the higher the positioning accuracy is. In this embodiment, the belt teeth 210 are stamped and formed on the transmission steel belt 21.

[0135] like Fig.11 As shown, a guide structure 24 is also provided on the transmission path of the transmission steel belt 21. The guide structure 24 includes a second support frame 241, a guide rod 242 and a guide assembly. The guide rod 242 is provided corresponding to the linear transmission part 211 of the transmission steel belt 21. The guide rod 242 is parallel to the linear transmission part 211 and is provided on the inner side of the transmission steel belt 21. The second support frame 241 is fixed on the frame 1. The guide rod 242 is fixedly mounted on the second support frame 241. The second support frame 241 extends into the inner side of the transmission steel belt 21. The two guide rods 242 on the inner side of the same transmission steel belt 21 are simultaneously fixed on the second support frame 241. Figure 7 (Only part of the third guide wheel 243 is shown for illustration) and Fig.12 As shown, the guide assembly is arranged on the inner side of the transmission steel belt 21 and has a guide groove matching the guide rod 242. In this embodiment, the guide assembly includes two rows of third guide wheels 243 arranged at the upper and lower edges, each third guide wheel 243 is rotatably arranged on the transmission steel belt 21, the axis of the third guide wheel 243 is arranged horizontally, and an annular groove is opened on the outer peripheral side of each third guide wheel 243, and a guide groove is formed between the annular grooves of the upper and lower rows of third guide wheels 243. The guide structure 24 guides the transmission steel belt 21 to be transmitted in a straight line and plays a certain supporting role on the transmission steel belt 21 and the hanger 3 located on the transmission steel belt 21, thereby improving the stability of the operation of the hanger 3 and the uniformity of electroplating.

[0136] like Fig.13 As shown, the first guide assembly includes two sets of first guide rails 4, which are horizontally distributed and arranged in parallel on both sides of the hanging plate 30. The first matching portion 31 is connected across the first guide rails 4 on both sides and moves along the first guide rails 4. In this embodiment, Figure 8 As shown, the first matching portion 31 includes two sets of first guide wheels 311, and the axes of the two sets of first guide wheels 311 are horizontally arranged and symmetrically distributed on both sides of the hanging plate 30, as shown in FIG. Fig.13As shown, the first guide wheel 311 is rollingly arranged on the first guide rail 4. A transition guide assembly is arranged in the transfer section G, and the transition guide assembly is arranged to extend in the same direction as the first guide assembly. In the extension direction, they are in an upper and lower position relationship and partially overlap in space to form a transition portion, so that the hanger 3 is simultaneously hung on the transition guide assembly before it is separated from the first guide assembly. In this embodiment, the transition guide assembly is arranged at a high position and partially overlaps with the first guide assemblies in the loading section A and the unloading section E to form a transition portion.

[0137] like Fig.13 As shown, the transition guide assembly includes at least two second guide rails 55, which are spaced apart from each other in the vertical direction and are arranged in parallel on the same side of the hanging plate 30. Figure 8 As shown, the second matching portion 32 includes at least two groups of second guide wheels 321, which are distributed on the same side surface of the hanging plate 30 at intervals in the vertical direction. Any group of second guide wheels 321 is symmetrically arranged about the center line extending vertically of the hanging plate 30, and the second guide wheels 321 are suitable for corresponding and rolling on the second guide rail 55.

[0138] In this embodiment, two first guide wheels 311 are provided in each group of first guide wheels 311, and the two first guide wheels 311 in each group are respectively located at the top corners above the same side panel surface, and the first guide wheels 311 are respectively fixed to the hanging plate 30 through connecting rods 312, and the connecting rods 312 are axially arranged horizontally, and the first guide wheels 311 are coaxially rotatably sleeved on the ends of the connecting rods 312, and the first guide wheels 311 on the same side are symmetrically arranged about the center line of the vertical direction of the side panel surface of the hanging plate 30, such as Fig. 9 As shown, two groups of first guide wheels 311 are symmetrically arranged on both sides of the hanging plate 30 .

[0139] like Fig.13 As shown, two first guide rails 4 are provided, that is, one first guide rail 4 is provided in each group of first guide rails 4, and they are symmetrically arranged on both sides of the hanging plate 30. The first guide rails 4 are mounted on the frame 1, and the first guide wheels 311 on the same side are suitable for rolling on the first guide rails 4. In this embodiment, the first guide rails 4 adopt circular tubular guide rails, and annular grooves are provided on the outer peripheral sides of all corresponding first guide wheels 311. The arc shape of the annular grooves matches the first guide rails 4, so that the first guide wheels 311 can slide linearly along the first guide rails 4.

[0140] For example Figure 8 As shown, in this embodiment, two sets of second guide wheels 321 are arranged, which are distributed on the plate surface on the same side of the hanging plate 30 at intervals in the vertical direction, and the axis of the second guide wheel 321 located at the top is arranged to be tilted downward to form an effect of hooking on the second guide rail 55. Any set of second guide wheels 321 is suitable for rolling on the second guide rail 55, and two corresponding second guide rails 55 are arranged, such as Figure 8 or Fig. 9 As shown, the axis of the group of second guide wheels 321 located at the top is tilted downward, and the tilt angle is consistent. The mounting plate 322 is tilted and fixed on the hanging plate 30. The axis of the group of second guide wheels 321 located at the top is vertically and rotatably arranged on the mounting plate 322. The axis of the group of second guide wheels 321 located at the bottom is horizontally arranged. In this embodiment, the group of second guide wheels 321 located at the bottom is arranged close to the plate surface of the hanging plate 30, and cooperates with the second guide wheels 321 with the axis tilted downward on the top to form a stable single-side limit for the hanging plate 30. The second guide wheels 321 can also be arranged in three or four groups, etc., and the corresponding second guide rails 55 can be arranged in three or four groups, etc., depending on specific needs. For example, when three groups are arranged, they are the first group, the second group and the third group from top to bottom, respectively. The second guide wheels 321 can be arranged in different combinations, such as the axis of the first group is tilted downward, and the axis of the second and third groups is arranged horizontally; or the axis of the first and second groups is tilted downward, and the axis of the third group is arranged horizontally; or the axis of the three groups of second guide wheels 321 are all tilted downward. Of course, the downward inclination angle of the axis between each group can be different, as long as the hanging plate 30 can be limited on the second guide rail 55. The specific combination depends on specific needs.

[0141] like Figure 8 As shown, in the present embodiment, each group of second guide wheels 321 is provided with two second guide wheels 321, and the two second guide wheels 321 are symmetrically arranged about the center line extending in the vertical direction of the hanging plate 30, and the connecting line of the positive projections of the four second guide wheels 321 on the same side on the hanging plate 30 forms an isosceles trapezoid, and of course can also form a rectangle. Three or four second guide wheels 321 can also be provided in each group, and so on, depending on specific needs.

[0142] The second guide rail 55 is mounted on the frame 1, and the second guide rail 55 is set corresponding to each group of second guide wheels 321. In this embodiment, the second guide rail 55 adopts a circular tube guide rail, and an annular groove is provided on the outer peripheral side of all corresponding second guide wheels 321. The arc shape of the annular groove matches the second guide rail 55, so that the second guide wheel 321 can slide linearly along the second guide rail 55.

[0143] The first guide wheel 311 , the second guide wheel 321 and the third guide wheel 243 are all made of plastic material, such as nylon wheels, which are wear-resistant and corrosion-resistant.

[0144] In this embodiment, the process of the hanging device 3 in the hanging section G is as follows:

[0145] like Fig.13As shown in the figure (in order to clearly indicate the matching relationship of the transfer and hanging process, some irrelevant structures are omitted in the figure), the hanging plate 30 runs from the first guide assembly on the left to the transition guide assembly on the right, the first guide rail 4 is set in the left translation section, and the second guide rail 55 is set in the right transfer and hanging section. The first guide rail 4 and the second guide rail 55 are simultaneously set at the intersection of the translation section and the transfer and hanging section G. In the left translation section, the hanging plate 30 runs along the first guide rail 4 through the first guide wheels 311 on both sides. When entering the intersection, the second guide wheel 321 is simultaneously rolled on the second guide rail 55, and the hanging plate 30 continues to run rightward along the second guide rail 55 to enter the transfer and hanging section G. Since the upper and lower sets of second guide wheels 321 can limit the hanging plate 30 as a whole on one side on the second guide rail 55 by hooking, the first guide rail 4 can be omitted on the transfer and hanging section G, or the first guide rail 4 on the side of the hanging plate 30 facing away from the second guide rail 55 can be removed. After entering the transfer and hanging section G, the transfer and hanging device 502 in the transfer and hanging section G can be used to lift the hanging plate 30 to a certain height so that the hanging plate 30 can be separated from the second guide rail 55, and then the hanging plate 30 can be horizontally moved to the side away from the second guide rail 55 and placed on another parallel line body. Of course, the transfer and hanging process can be reversed, which will not be repeated here.

[0146] Each of the rotating hanging devices 502 includes a second moving mechanism and a second clamping assembly, such as Fig.14 As shown, the second moving mechanism is a two-dimensional moving structure, that is, suitable for moving in the horizontal direction and the vertical direction, specifically, two linear modules arranged perpendicular to each other, and the first linear module 51 arranged in the vertical direction is fixed to the second linear module 52 arranged in the horizontal direction through a plate and is suitable for overall movement in the horizontal direction. In this embodiment, the second linear module 52 is set between two parallel running paths, that is, between the loading confirmation position and the cleaning tank, and between the washing position D1 and the unloading position E1 of the post-processing section D. The second clamping assembly is fixed to the first linear module 51 through a triangular bracket, as shown in FIG. Fig.15 As shown, in this embodiment, the second clamping assembly includes a third driver 53 and two linked clamping jaws 54. A conventional linkage structure is adopted between the driving end of the third driver 53 and the two clamping jaws 54. The third driver 53 is suitable for driving the two clamping jaws 54 to perform synchronous clamping or releasing actions. The lifting part 34 on the hanging plate 30 is provided with hook grooves corresponding to the two clamping jaws 54. The two clamping jaws 54 are suitable for shrinking inward and clamping on the corresponding hook grooves to clamp the fixed hanger 3. The plane where the two clamping jaws 54 are located is perpendicular to the second linear module 52.

[0147] When the hanger 3 is transferred from the high loading confirmation position to the low cleaning tank, the second linear module 52 drives the first linear module 51 to move above the hanger 3, so that the second clamping assembly is directly opposite the hanger 3 below, the first linear module 51 drives the second clamping assembly to move downward and clamps the hanger 3 with the clamping claw 54, the first linear module 51 drives the second clamping assembly to move upward slightly together with the hanger 3 to make the second guide wheel 321 disengage from the second guide rail 55, and then the second linear module 52 drives the hanger 3 to move horizontally above the cleaning tank, and the first linear module 51 drives the second clamping assembly to move downward together with the hanger 3 The hanger 3 is moved to move the workpieces to be processed under the hanger 3 into the cleaning tank, and at the same time, the first guide wheels 311 on both sides are correspondingly arranged on the first guide rails 4 above the cleaning tank to complete the transfer of the hanger 3; when the hanger 3 is transferred from the water washing position D1 of the low-position post-processing section D to the high-position unloading position E1, the above process is reversed, that is, the second clamping assembly clamps the hanger 3 and moves upward and disengages from the first guide rail 4. The height of the upward movement makes the workpieces to be processed under the hanger 3 completely disengage from the tank body of the water washing position D1, and then it moves horizontally to the lower material position E1, so that the second guide wheel 321 is correspondingly hung on the second guide rail 55 to complete the transfer.

[0148] The setting of the transfer section G greatly reduces the lifting height of the hanging plate 30 during transfer. It only needs to be lifted a few centimeters to be off the guide rail for translation operation, which greatly improves the working efficiency of the transfer of the hanging plate 30 and the safety factor of the operation.

[0149] In this embodiment, a hanging device 501 is arranged between the first guide assembly and the second guide assembly to facilitate the transfer of the hanger 3 between the first guide assembly and the second guide assembly. The hanging device 501 includes a first moving mechanism and a first clamping assembly. In this embodiment, the first moving mechanism and the second moving mechanism use the same two linear modules arranged in the vertical direction and the horizontal direction, and the first clamping assembly and the second clamping assembly also use the same component structure. The difference is that the plane where the two clamping claws 54 in the first clamping assembly are located is arranged parallel to the second linear module 52. Two groups of hanging devices 501 are arranged, which are respectively arranged between the pre-preg position of the pre-treatment section B and the initial end of the electroplating section C, and between the end of the electroplating section C and the washing position D1 of the post-treatment section D, as shown in FIG. Figure 3As shown, taking the hanging device 501 at the end of the electroplating section C as an example, the second linear module 52 spans between the electroplating section C and the post-processing section D. When the hanger 3 is transferred from the electroplating section C to the washing position D1 of the post-processing section D, the second linear module 52 drives the first linear module 51 and the first clamping assembly to move above the hanger 3 in the electroplating section C. The first linear module 51 drives the first clamping assembly to move downward and clamp the fixed hanger 3, and then moves the hanger 3 together with the workpiece to be processed below upward for a certain distance, so that the third matching part 33 is separated from the transmission steel belt 21. After the workpiece to be processed is completely separated from the electroplating tank body, the second linear module 52 drives the first linear module 51 together with the hanger 3 to move horizontally to the right to above the washing position D1 of the post-processing section D. The first linear module 51 lowers the hanger 3 so that the first guide wheel 311 is correspondingly arranged on the first guide rail 4 above the washing position D1 to complete the transfer.

[0150] The first drive assembly 6 is provided on the hanger conveying system, which is suitable for driving the hanger 3 to run along the first guide assembly. The first drive assembly 6 includes a first driver 60 and a plurality of drive parts. The plurality of drive parts are linked by the first driver 60. In this embodiment, the drive part is a reciprocating swing rod 65, such as Fig.17 As shown, the first driver 60 is a combination of a third linear module 61 and a push rod cylinder 62, the push rod cylinder 62 is fixed on the first connecting rod 63, the first connecting rod 63 is extended along the running direction of the hanger 3 and is located on one side of the hanger 3, the swing rod 65 is evenly spaced and hinged in the middle on the first connecting rod 63, the first connecting rod 63 is fixed on the third linear module 61, and is suitable for translation along the running direction of the hanger 3 with the third linear module 61, the push rod cylinder 62 is fixed at the end of the first connecting rod 63, the driving end of the push rod cylinder 62 is hingedly connected to the second connecting rod 64, the second connecting rod 64 is arranged parallel to the first connecting rod 63, and the tail of the swing rod 65 is hinged on the second connecting rod 64. Fig.17 For example, during operation, the push rod of the push rod cylinder 62 contracts, and the second connecting rod 64 drives all the rocker rods 65 to rotate around the hinge point with the first connecting rod 63, so that the front end of the rocker rod 65 avoids the hanger 3, and then the third linear module 61 pushes the first connecting rod 63 together with the push rod cylinder 62, the second connecting rod 64 and the rocker rod 65 thereon to translate to the right. When the rocker rod 65 moves to the next hanger 3, the push rod of the push rod cylinder 62 is pushed out, and the rocker rod 65 rotates around the hinge point with the first connecting rod 63, so that the front end of the rocker rod 65 rests on the hanging plate 30, and the push rod cylinder 62 maintains this state, and then the third linear module 61 translates in the opposite direction, and pushes the hanger to translate to the left at the same time through the rocker rod 65, and so on and so forth, so as to realize the intermittent operation of the hanger 3.

[0151] In this embodiment, a telescopic structure 35 is provided below the hanging plate 30. Figure 8As shown, the clamp 36 is fixed under the telescopic structure 35. The setting of the telescopic structure 35 is convenient for adapting to different widths of the workpieces to be processed. Because one hanger 3 corresponds to one workpiece to be processed, when the width of the workpiece to be processed is large, such as Fig.18 As shown, the telescopic structure 35 is unfolded to increase the clamping width of the hanger 3. When the width of the workpiece to be processed is small, as shown in FIG. Fig.19 As shown, the telescopic structure 35 is retracted to fully save space to reduce the clamping width of the hanger 3. Therefore, when the hanger is adjusted at the E2 of the unloading section E, the empty hanger 3 can be retracted to the shortest to reduce the space occupied by the hanger temporary storage section F, so that the number of hangers 3 stored in the hanger temporary storage section F is increased within the same space, and the width of the hanger 3 can be adjusted according to the width of the workpiece to be processed at the hanger adjustment position E2 of the loading section A. In this embodiment, the telescopic structure 35 can be a telescopic structure 35 in an existing electroplating hanger, and the specific structure is not repeated here.

[0152] In this embodiment, Fig. 20 As shown, a transfer mechanism 7 is provided between the hanger temporary storage section F and the material loading section A. The transfer mechanism 7 is suitable for continuously transferring a single hanger 3 from the hanger temporary storage section F to the material loading section A. The transfer mechanism 7 includes a sliding component 71 and a carrying component 72. Fig.21 As shown, the sliding assembly 71 includes a sliding rack 711, a sliding gear 712 meshing with the sliding rack 711, a sliding guide rail 713 and a sliding slider 714 slidably arranged on the sliding guide rail 713. The carrying assembly 72 is fixed on the sliding slider 714 and is suitable for sliding along the sliding guide rail 713. The sliding rack 711 and the sliding guide rail 713 are arranged at an upper and lower interval, and both extend along the running direction of the hanger 3 and are fixed on the frame 1. In this embodiment, two sliding guide rails 713 are arranged, and the two sliding guide rails 713 are arranged in parallel in the horizontal direction. The sliding rack 711 is located above the two sliding guide rails 713 and is equal to the distance between the two sliding guide rails 713. The carrying assembly 72 includes a carrying frame 721, a carrying motor 722 and a third clamping portion 723. In the present embodiment, four sliding sliders 714 are provided, which are respectively provided at the four vertex corners of the carrying frame 721. The carrying motor 722 is provided above the carrying frame 721. The driving end of the carrying motor 722 is fixed with the sliding gear 712. When the carrying motor 722 is started, the sliding gear 712 is driven to rotate and mesh with the sliding rack 711 for transmission, thereby driving the carrying assembly 72 to slide along the sliding guide rail 713. The third clamping portion 723 is provided with a clamping structure identical to that of the first clamping assembly and the second clamping assembly, which will not be described in detail here.

[0153] The first driving assembly 6 located on the running path of the transfer mechanism 7 makes an adaptive deformation, and only uses the first connecting rod 63, which is extended along the running direction of the hanger 3 and is arranged above the hanger 3. A plurality of swing rods 65 are evenly spaced thereon, and a plurality of limiting parts are arranged on the first connecting rod 63 corresponding to the swing rod 65 one by one. The limiting part is provided with a limiting groove with an opening facing the running direction of the hanger 3 and facing directly below. The swing rod 65 is hingedly arranged in the limiting groove, and is subjected to the self-weight of the swing rod 65 to prevent the swing rod 65 from being moved. Fig.21 For example, under normal conditions, the rocker arm 65 remains in a vertical state. During operation, the third linear module 61 pushes the first connecting rod 63 to move to the left, and the rocker arm 65 abuts against the first supporting frame 332 of the rear hanger 3 and has a tendency to swing to the right. At this time, the limiting slot opening facing the running direction of the hanger 3 plays a role of giving way to the rocker arm 3. After the third linear module 61 pushes the rocker arm 65 to move to the position of the rear hanger 3, the rocker arm 65 naturally droops due to gravity. At this time, the third linear module 61 drives the first connecting rod 63 to move to the right, and the rocker arm 65 abuts against the first supporting frame 332 of the rear hanger 3. Due to the action of the limiting portion, the rocker arm 65 cannot swing to the left and can only exert a force to the right on the hanger 3 to push the hanger 3 to move in the running direction. Since the speed at which the swing rod 65 pushes the hanger 3 to move intermittently is slow, it takes a long time to move from the hanger temporary storage section F through the transfer position to the hanger adjustment position E2, which cannot adapt to the loading speed of the loading position. At this time, the hanger 3 is clamped and fixed by the transfer mechanism 7, and is quickly transferred to the loading section A after the swing rod 65 gives way to meet the loading needs.

[0154] by Figure 1 Taking the example shown, the running path of the hanger 3 is: hanger temporary storage section F-transfer empty position-hanger adjustment position E2-loading position-loading confirmation position-transfer to the upper line-cleaning tank-water washing position D1-pre-impregnation position-electroplating section C-water washing position D1-transfer to the lower line-unloading position E1-hanger adjustment position E2-peeling position E3-water washing position D1-drying position-hanger temporary storage section F, so as to carry out the circulation transmission of hanger 3, wherein the pre-impregnation, peeling and other processes are conventional electroplating processes, which will not be repeated here.

[0155] As a first replaceable implementation of Example 1, both of the two circulating transmission devices 2 can adopt a combination of a chain, a driving gear and a driven gear. The chain is tensioned and wound around the driving gear and the driven gear. The driving gear and the driven gear are axially arranged horizontally. The evenly spaced holes on the chain are used as matching holes adapted to the hanger 3. A protrusion is provided at the bottom of the third matching portion 33 of the hanger 3 to be embedded in the corresponding matching hole to form a linkage arrangement of the hanger 3 and the circulating transmission device 2.

[0156] As a second alternative implementation of Example 1, the two endless transmission devices 2 can be arranged such that the transmission shaft 23 of one endless transmission device 2 extends in the vertical direction, and the transmission shaft 23 of the other endless transmission device 2 extends in the horizontal direction. It is sufficient to ensure that the belt teeth 210 or tooth grooves 3330 provided in the two endless transmission devices 2 are at the same height.

[0157] As a third alternative implementation of Example 1, the interlocking structure can also be adopted by providing a convex portion on one of the transmission steel belt 21 and the third matching portion 33, and providing a concave portion on the other. For example, bosses are evenly provided along the transmission steel belt 21, and corresponding grooves are evenly provided on the third matching portion 33, and the bosses are embedded in the corresponding grooves.

[0158] As a fourth replaceable implementation of Example 1, the guide assembly can be two rows of gears arranged up and down, and racks are set on both sides of the guide rod 242 corresponding to the gears. The gears and racks are meshed together to limit the guide rod 242 between the two rows of gears.

[0159] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
