Description

Technical Field

[0001] The present invention relates to the technical field of electroplating, and particularly relates to a titanium alloy electroplating device. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the principle of electrolysis. It is a process of using electrolysis to make the surface of metal or other material parts adhere to a metal film, so as to prevent metal oxidation, improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance beauty. Electroplating equipment mainly includes an electroplating tank, a power supply, an anode, a cathode, electroplating solution and workpieces to be electroplated. During the electroplating process, the workpieces to be electroplated need to be connected to the cathode, and then the power supply is turned on. Metal ions in the electrolyte gradually adsorb onto the workpieces to be electroplated to form a coating.

[0003] A Chinese patent with the authorization announcement number CN114381788B discloses an electroplating clamping device for the production and processing of hollow parts of fitness equipment, which relates to the technical field of fitness equipment processing, including: a fixed top seat; four support rods are connected in a surrounding manner at the bottom of the fixed top seat; the movable base is located at the bottom of the fixed top seat, and four connecting rods are connected in a surrounding manner at the top of the movable base, and the connecting rods are connected to the support rods, and the movable base is connected to the fixed top seat through the connecting rods and the support rods; the inside of the pull rod is hollow, the top of the pull rod is connected to the inside of the fixed top seat, and the bottom end of the pull rod is rotatably connected to the inside of the movable base; there are four support rods in total. According to the inner diameter size of the hollow parts, the interval distance of the four movable rods is adjusted to better meet the support and fixation effects of different specifications of hollow parts. It solves the problem that the traditional electroplating clamping device can only be used for the support and fixation of hollow parts with a single inner diameter, and cannot be adjusted adaptively according to the different specifications of hollow parts, and has a high limitation in use.

[0004] During the implementation of the electroplating process, the workpieces to be electroplated need to be fixed by fixtures and then enter the electroplating solution for electroplating. Due to the occlusion and limitation of the fixtures at the clamped parts of the workpieces, blind spots are formed in the electroplating operation, resulting in the inability of this area to fully contact the electroplating solution and undergo electrochemical reactions, and then the phenomenon of electroplating layer deficiency occurs, seriously affecting the overall electroplating effect. Summary of the Invention

[0005] The present invention provides a titanium alloy electroplating device, aiming to solve the technical problem that in the related art, due to the occlusion and limitation of the fixtures at the clamped parts of the workpieces, blind spots are formed in the electroplating operation, resulting in the inability of this area to fully contact the electroplating solution and undergo electrochemical reactions, and then the electroplating layer deficiency occurs.

[0006] A titanium alloy electroplating device of the present invention comprises: an electroplating pool, a conveying module is provided on the electroplating pool, the conveying module comprises a conveying unit, the conveying unit comprises a driving wheel extending along an axis line in the front-back direction and rotating on the electroplating pool, a conveying chain is installed on the driving wheel for transmission, and the conveying module also comprises a clamping unit and a lifting drive unit; the clamping unit comprises a plurality of clamping assemblies fixed to the conveying chain in a circumferential direction, the clamping assemblies comprise two bearing seats fixed on the conveying chain at intervals on the left and right, and sliding seats are elastically slidably connected up and down on the bearing seats, one of the sliding seats is provided with a clamping rod for bearing an electroplated workpiece and a horizontally arranged driving rod, and the two sliding seats are fixedly connected by a connecting piece so that the two sliding seats can be lifted and lowered synchronously; the lifting drive unit comprises a driving frame fixed in the electroplating pool, the driving frame has a plurality of ascending sections and descending sections, the ascending sections and the descending sections are connected end to end and are alternately arranged in the left and right directions, and the driving rod abuts against the driving frame so that the sliding seat is lifted and lowered; a shifting rod is also fixedly installed in the electroplating pool along the left and right directions, and when the electroplated workpiece is lifted and lowered, the shifting rod abuts against the electroplated workpiece so that the electroplated workpiece is rotated.

[0007] In the process of the left bearing seat and the right bearing seat driving the electroplated workpiece to move to the right, the driving rod will gradually abut against the driving frame, so that when the driving rod gradually passes through the ascending section, the connecting section and the descending section, the driving rod will be continuously lifted and lowered, so that the electroplated workpiece will be continuously lifted and lowered in the process of moving to the right. When the electroplated workpiece rises, the shifting rod gradually abuts against the fourth side plate of the electroplated workpiece, thereby forcing the electroplated workpiece to swing to the right until the shifting rod passes over the right-angled end point of the third side plate and the left end of the fourth side plate on the electroplated workpiece. When the electroplated workpiece descends, the shifting rod will generate an upward thrust on the third side plate on the electroplated workpiece, thereby pushing the electroplated workpiece to rotate clockwise until the clamping rod reaches the right-angled end point of the left end of the third side plate and the fourth side plate. As the electroplated workpiece is continuously lifted and lowered, the electroplated workpiece is rotated multiple times, and the clamping position of the clamping rod on the electroplated workpiece is continuously changed. The continuous lifting of the electroplating workpiece can disturb the plating solution in the electroplating pool up and down, making the metal ions in the upper and lower layers of the plating solution more evenly distributed, thereby improving the electroplating effect of the electroplated workpiece. In addition, the lifting of the electroplated workpiece allows the lever to push the electroplated workpiece, forcing the electroplated workpiece to continuously rotate and continuously change the clamping position of the clamping rod on the electroplated workpiece, thereby avoiding the occurrence of electroplating blind spots and allowing the electroplated workpiece to receive comprehensive electroplating treatment.

[0008] Preferably, the connecting member is a telescopic plate installed on one of the sliding seats, and a slot is provided on the other sliding seat at a position corresponding to the telescopic plate.

[0009] When both sliding seats rotate to the bottom of the conveying chain, the telescopic portion of the telescopic plate is inserted into the slot, which can ensure that the two sliding seats rise and fall synchronously.

[0010] Preferably, a loading platform is provided on the electroplating bath. A turning plate is rotatably installed on the right side of the loading platform through an elastic member. A guiding frame is also fixedly installed on the electroplating bath. Guide columns are provided on the sliding seats. When the sliding seats pass through the guiding frame, the guide columns abut against the guiding frame, so that the sliding seats contract into the bearing seats.

[0011] The loading platform can convey electroplated workpieces and send the electroplated workpieces between the left bearing seat and the right bearing seat.

[0012] Preferably, the guiding frame has a vertical section, an arc section and a horizontal section, which are connected in sequence.

[0013] The guiding frame can drive the driving rod to lift, so that the electroplated workpieces are continuously lifted and lowered during the rightward conveying process.

[0014] Preferably, the driving frame also has a conveying section, which is horizontally arranged in the left-right direction.

[0015] Preferably, support columns are fixedly installed at the bottom of the electroplating bath. An inclined plate is fixedly installed at a position near the upper end on the left side of the support column. The inclined plate slopes upward gradually from left to right. A blanking plate is fixedly installed at a position near the upper end on the right side of the support column. The blanking plate slopes downward gradually from left to right, and the blanking plate extends to the outside of the electroplating bath.

[0016] Preferably, two clamping units are provided, and the two clamping units are symmetrically arranged front and back.

[0017] Two clamping units are arranged front and back, so that when the conveying chain rotates, two workpieces to be electroplated can be sent to the clamping units at the same time, improving work efficiency.

[0018] Preferably, two baffles are arranged at intervals in the front and back directions at a position near the right side of the upper surface of the loading platform, and the length direction of the baffles extends in the left-right direction. A guiding plate is arranged between the two baffles. The guiding plate divides the space between the two baffles into two front and back conveying channels, and the two conveying channels correspond to the two clamping units respectively.

[0019] Preferably, a top block is also provided on the sliding seat opposite to the clamping rod among the left and right sliding seats.

[0020] Preferably, a plurality of rotating rollers are rotatably installed on the blanking plate and arranged at intervals in the left-right direction.

[0021] With the above technical solution, the beneficial effects of the present invention are as follows: During the process of the left bearing seat and the right bearing seat driving the electroplated workpiece to move to the right, the driving rod will gradually abut against the driving frame. Thus, when the driving rod gradually passes through the rising section, the connecting section, and the falling section, the driving rod will continuously rise and fall, so that during the process of the electroplated workpiece moving to the right, it will continuously rise and fall. When the electroplated workpiece rises, the dial rod gradually abuts against the fourth side plate of the electroplated workpiece, thereby forcing the electroplated workpiece to swing to the right until the dial rod crosses the right-angle endpoint of the third side plate and the left end of the fourth side plate on the electroplated workpiece. When the electroplated workpiece descends, the dial rod will generate an upward thrust on the third side plate of the electroplated workpiece, thereby pushing the electroplated workpiece to rotate clockwise until the clamping rod reaches the right-angle endpoint of the third side plate and the left end of the fourth side plate. With the continuous rise and fall of the electroplated workpiece, the electroplated workpiece rotates multiple times, continuously changing the clamping position of the clamping rod on the electroplated workpiece. The continuous rise and fall of the electroplated workpiece can disturb the electroplating solution in the electroplating tank up and down, making the distribution of metal ions in the upper and lower layers of the electroplating solution more uniform, thereby improving the electroplating effect of the electroplated workpiece. Moreover, by using the rise and fall of the electroplated workpiece, the dial rod pushes against the electroplated workpiece, forcing the electroplated workpiece to continuously rotate and continuously changing the clamping position of the clamping rod on the electroplated workpiece, thereby avoiding the occurrence of electroplating blind spots and enabling the electroplated workpiece to be comprehensively electroplated.

Detailed implementation manners

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0035] As Figures 1 to 11 shown, in a specific embodiment of a titanium alloy electroplating device of the present invention, for the convenience of understanding, the electroplated workpiece 13 is used as the application scenario of the present invention. The electroplated workpiece 13 has a concave cavity. The titanium alloy electroplating device includes a loading module, a feeding module, a conveying module, and a discharging module.

[0036] As Figure 1 , Figure 2 and Figure 3 shown, the loading module includes a support platform 10 and an electroplating bath 11. The support platform 10 is of a rectangular structure. In this embodiment, the length direction of the support platform 10 is defined as the left-right direction, and the width direction of the support platform 10 is defined as the front-back direction. Platforms are provided on both the front and back sides of the support platform 10, and workers can stand above the platforms, which is convenient for workers to observe the working conditions. Lifting equipment (not shown in the figure) can be installed above the support platform 10, which is convenient for lifting operations as needed.

[0037] Inside the support platform 10, there is an electroplating bath 11. The electroplating bath 11 is also rectangular in structure, and the length direction of the electroplating bath 11 extends along the left - right direction. The electroplating bath 11 is filled with electroplating solution for electroplating the electroplated workpiece 13. On the right side surface of the electroplating bath 11, there is a discharge port 12 that penetrates through from left to right, and the discharge port 12 facilitates the electroplated workpiece 13 that has completed electroplating to be conveyed out of the electroplating bath 11.

[0038] As Figure 1 shown, the loading module is used to provide the electroplated workpiece 13 to be processed to the conveying module. The loading module includes a loading platform 20, a baffle 21, a guide plate 22, a turning plate 23, and a guide frame 24. Figure 8

[0039] The loading platform 20 is fixedly installed on the support platform 10 through a fixing frame. The loading platform 20 is horizontally arranged, and the length direction of the loading platform 20 extends along the left - right direction. The electroplated workpiece 13 can be conveyed from the left side to the right side on the upper surface of the loading platform 20. The loading platform 20 is located above the electroplating bath 11 near the left side, and the bottom of the loading platform 20 abuts against the upper surface of the electroplating bath 11. It should be emphasized that the right end of the loading platform 20 passes through the left side surface of the electroplating bath 11.

[0040] At the position near the right side of the upper surface of the loading platform 20, there are two baffles 21 arranged at intervals in the front - rear direction. The baffle 21 is perpendicular to the loading platform 20, and the length direction of the baffle 21 extends along the left - right direction.

[0041] A guide plate 22 is arranged between the front and rear baffles 21. The length direction of the guide plate 22 extends along the left - right direction, so that the guide plate 22 divides the space between the two baffles 21 into two front - rear conveying channels. The left end of the guide plate 22 is provided with inclined diversion surfaces at both the front and the rear (as Figure 8 shown), so as to facilitate the electroplated workpiece 13 on the upper surface of the loading platform 20 to enter the two front - rear conveying channels respectively. It should be specifically noted that a pushing mechanism (not shown in the figure) is also installed on the loading platform 20, and the pushing mechanism can push the electroplated workpiece 13 to the right, so that the electroplated workpiece 13 can enter the two conveying channels respectively.

[0042] The turning plate 23 is rotatably installed on the right side of the loading platform 20 through an elastic member. The turning plate 23 can rotate along the axis extending in the front - rear direction. In this embodiment, the elastic member is a torsion spring or a coil spring, and the elastic member can provide elastic force for the reset of the turning plate 23.

[0043] As Figure 1 shown, and Figure 9As shown, guide frames 24 are provided on both the front and rear sides of the loading platform 20, and the guide frames 24 are fixedly installed on the electroplating bath 11. The guide frame 24 has a vertical section 28, an arc section 25, and a horizontal section 26, which are connected in sequence. The lower end of the vertical section 28 is connected to the arc section 25, the end of the arc section 25 is connected to the horizontal section 26, and the length direction of the horizontal section 26 extends in the left-right direction.

[0044] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 10 , Figure 11 shown, the conveying module includes a conveying unit, a clamping unit, and a lifting drive unit.

[0045] As Figure 3 with Figure 4 shown, the conveying unit includes a stress plate 30, a bracket 31, a driving wheel 32, and a conveying chain 33.

[0046] Stress plates 30 are fixedly installed on both the front and rear sides of the electroplating bath 11. Two brackets 31 are fixedly installed at left-right intervals on each stress plate 30, and the two brackets 31 on the front side and the two brackets 31 on the rear side are arranged correspondingly. That is, the two brackets 31 on the left are arranged front and rear relatively, and the two brackets 31 on the right are also arranged front and rear relatively.

[0047] Driving wheels 32 are rotatably installed between the two brackets 31 on the left and between the two brackets 31 on the right, and the driving wheels 32 rotate about an axis extending in the front-rear direction. A conveying chain 33 is drivingly installed on the driving wheel 32, and a motor for driving the driving wheel 32 to rotate is installed on the bracket 31. The motor drives the driving wheel 32 to rotate, so that the driving wheel 32 drives the conveying chain 33 to rotate. The clamping unit is installed on the conveying chain 33, so that the conveying chain 33 can drive the clamping unit to rotate.

[0048] As Figure 3 with Figure 7 shown, two clamping units are provided, and the two clamping units are installed on the conveying chain 33 at front-rear intervals, and the front and rear two clamping units are symmetrically arranged. The two clamping units correspond to the two conveying channels on the loading platform 20 respectively.

[0049] Each clamping unit includes a plurality of clamping components, and the clamping components are fixedly installed on the conveying chain 33 and are uniformly distributed along the circumferential direction of the conveying chain 33.

[0050] Each clamping assembly includes a left bearing seat 40, a left sliding seat 41, a clamping rod 42, a first guide post 43, a driving rod 44, a telescopic plate 45, a right bearing seat 50, a right sliding seat 51, a top block 52 and a second guide post 53.

[0051] The left bearing seat 40 and the right bearing seat 50 are fixedly installed on the conveying chain 33 at intervals left and right. As the conveying chain 33 rotates, when the left bearing seat 40 and the right bearing seat 50 are above or below the conveying chain 33, their states are different. That is, in this embodiment, when the left bearing seat 40 and the right bearing seat 50 are above the conveying chain 33, the left bearing seat 40 is on the right side of the right bearing seat 50, and when the left bearing seat 40 and the right bearing seat 50 are below the conveying chain 33, the left bearing seat 40 is on the left side of the right bearing seat 50 (as Figure 3 shown). For the convenience of understanding, the following will describe its specific structure in the state when the left bearing seat 40 and the right bearing seat 50 are below the conveying chain 33.

[0052] As Figure 7 shown, the left bearing seat 40 has a structure with a hollow interior and an open lower end. The left sliding seat 41 is slidably installed up and down inside the left bearing seat 40. The lower end of the left sliding seat 41 extends below the left bearing seat 40, and a spring is arranged inside the left bearing seat 40. One end of the spring is connected to the left bearing seat 40, and the other end is connected to the left sliding seat 41, so as to provide a restoring elastic force for the left sliding seat 41.

[0053] A clamping rod 42 is fixedly installed at a position near the lower end of the right side surface of the left sliding seat 41. In this embodiment, the clamping rod 42 has a columnar structure, and the axis of the clamping rod 42 extends in the left-right direction. A first guide post 43 is fixedly installed on the front side of the left sliding seat 41, and the axis of the first guide post 43 extends in the front-back direction.

[0054] A driving rod 44 is fixedly installed on the rear side of the left sliding seat 41, and the axis of the driving rod 44 extends in the front-back direction. It should be particularly emphasized that in this embodiment, the front clamping unit and the rear clamping unit share a driving rod 44, that is, the rear end of the driving rod 44 on the front left sliding seat 41 is fixed to the rear left sliding seat 41 (as Figure 5 shown).

[0055] A telescopic plate 45 is fixedly installed on the right side surface of the left sliding seat 41. The telescopic plate 45 can be telescoped in the left-right direction. In this embodiment, the telescopic plate 45 is composed of a fixed plate and a sliding plate. The fixed plate is fixedly installed on the left sliding seat 41, and the sliding plate is slidably assembled on the fixed plate through a spring, that is, the sliding plate can slide in the left-right direction.

[0056] The right bearing seat 50 also has a structure with a hollow interior and an open lower end. A right sliding seat 51 is slidably mounted up and down inside the right bearing seat 50. The lower end of the right sliding seat 51 extends below the right bearing seat 50, and a spring is arranged inside the right bearing seat 50. One end of the spring is connected to the right bearing seat 50, and the other end of the spring is connected to the right sliding seat 51, thereby providing a restoring elastic force to the right sliding seat 51.

[0057] A top block 52 is arranged on the left side of the right sliding seat 51 (the side opposite to the left sliding seat 41), and the top block 52 and the clamping rod 42 are arranged opposite to each other left and right.

[0058] A second guide post 53 is fixedly mounted on the front side of the right sliding seat 51. The axis of the second guide post 53 extends in the front-rear direction. The axis of the second guide post 53 and the axis of the first guide post 43 are on the same horizontal plane, and the length of the second guide post 53 is greater than the length of the first guide post 43.

[0059] A slot 54 is formed at the position of the left side surface of the right sliding seat 51 corresponding to the telescopic plate 45, and the moving end of the sliding plate can be inserted into the slot 54.

[0060] During operation, the conveying chain 33 drives the left bearing seat 40 and the right bearing seat 50 to rotate counterclockwise. When the left bearing seat 40 and the right bearing seat 50 rotate to the left turning point, the first guide post 43 and the second guide post 53 will abut against the guide frame 24. The first guide post 43 and the second guide post 53 first abut against the vertical section 28 of the guide frame 24, so that the left sliding seat 41 contracts into the left bearing seat 40, the spring is compressed, and the right sliding seat 51 also contracts into the right bearing seat 50 (as shown in Figure 4 ), the right bearing seat 50 will first rotate downward through the vertical section 28 and then enter the arc section 25. At this time, the left bearing seat 40 and the right bearing seat 50 change from being parallel to an eight-shaped structure. At this time, the pushing mechanism can push the electroplated workpiece 13 on the feeding platform 20 to the right, so that the electroplated workpiece 13 can enter the two conveying channels respectively, and the electroplated workpiece 13 is located on the upper surface of the turning plate 23, and the right end of the electroplated workpiece 13 extends between the left bearing seat 40 and the right bearing seat 50.

[0061] The left bearing seat 40 continues to rotate. The clamping rod 42 on the left sliding seat 41 will insert into the inside of the electroplated workpiece 13 and abut against the bottom surface of the groove. The left sliding seat 41 abuts against the upper surface of the electroplated workpiece 13. As the left bearing seat 40 rotates, it will push the electroplated workpiece 13 downward and to the right. The turning plate 23 is forced to rotate downward. Immediately afterwards, both the first guide post 43 and the second guide post 53 reach the arc section 25, and the electroplated workpiece 13 gradually separates from the turning plate 23 and is placed between the left bearing seat 40 and the right bearing seat 50. Since the right bearing seat 50 is still in an inclined state, the electroplated workpiece 13 will slide down along the inclined surface of the right bearing seat 50 and is finally blocked by the clamping rod 42. Then the left bearing seat 40 and the right bearing seat 50 continue to rotate, and the first guide post 43 and the second guide post 53 gradually enter the horizontal section 26. At this time, both the left bearing seat 40 and the right bearing seat 50 are in a vertical state, and the electroplated workpiece 13 is also completely hung on the clamping rod 42 (as Figure 6 shown). At this time, the bottom surface of the electroplated workpiece 13 is on the right side and abuts against the top block 52, and the clamping rod 42 is located at the inner corner of the electroplated workpiece 13. At this time, the telescopic end of the telescopic plate 45 also inserts into the slot 54.

[0062] It should be specifically noted that the guide frame 24 is provided to make the left sliding seat 41 and the right sliding seat 51 respectively contract into the left bearing seat 40 and the right bearing seat 50. In order to make the clamping rod 42 close to the left bearing seat 40, that is, when the electroplated workpiece 13 is conveyed to the right, it can be close to the included angle between the left bearing seat 40 and the right bearing seat 50, so as to prevent the clamping rod 42 from being unable to block the electroplated workpiece 13 when the left bearing seat 40 and the right bearing seat 50 rotate to the vertical state, resulting in the dropping of the electroplated workpiece 13.

[0063] When the first guide post 43 reaches the end of the horizontal section 26, the left sliding seat 41 and the right sliding seat 51 move downward simultaneously, and the elastic force of the spring is released, so that the electroplated workpiece 13 enters the electroplating solution for electroplating work.

[0064] As Figure 9 shown, the lifting drive unit includes a vertical plate 60, a drive frame 61, a rising section 62, a connecting section 63, a descending section 64 and a conveying section 65.

[0065] A vertical plate 60 is provided at the bottom of the electroplating tank 11, and a drive frame 61 is fixedly installed on the vertical plate 60. The drive frame 61 includes a plurality of rising sections 62, connecting sections 63, descending sections 64 and a conveying section 65. The rising sections 62 and the descending sections 64 are arranged alternately in the left-right direction, and the connecting section 63 connects the rising sections 62 and the descending sections 64, that is, the rising sections 62, the connecting sections 63 and the descending sections 64 form a wavy structure.

[0066] The ascending section 62 slopes gradually upward from left to right, the descending section 64 slopes gradually downward from left to right, the connecting section 63 is a horizontal structure, and the conveying section 65 is also a horizontal structure.

[0067] During the process of the left bearing seat 40 and the right bearing seat 50 driving the electroplating workpiece 13 to move to the right, the driving rod 44 will gradually abut against the driving frame 61. Thus, when the driving rod 44 gradually passes through the ascending section 62, the connecting section 63 and the descending section 64, the driving rod 44 will continuously move up and down, so that when the electroplating workpiece 13 moves to the right, it will continuously move up and down. The continuous lifting and lowering of the electroplating workpiece 13 can cause the electroplating solution in the electroplating tank 11 to be disturbed up and down, making the distribution of metal ions in the upper and lower layers of the electroplating solution more uniform.

[0068] As Figure 5 shown in Figure 6 As shown in the figure, two dial rods 70 are fixedly installed in the electroplating tank 11. The two dial rods 70 are arranged at intervals front and back, and the axes of the dial rods 70 all extend in the left-right direction. The two dial rods 70 are located between the front and rear clamping units. That is, the front dial rod 70 corresponds to the front clamping unit, and the rear dial rod 70 corresponds to the rear clamping unit. Hereinafter, the front dial rod 70 will be described. The front dial rod 70 is located behind the left sliding seat 41 and the right sliding seat 51.

[0069] As Figure 6 shown in the figure, the circumferential direction of the electroplating workpiece 13 has four side plates. Starting from the upper vertex and in the clockwise direction, they are the first side plate, the second side plate, the third side plate and the fourth side plate. That is, the side plate located in the upper left is the fourth side plate, and the side plate located in the lower left is the third side plate.

[0070] When the electroplating workpiece 13 rises, the dial rod 70 gradually abuts against the fourth side plate, thereby forcing the electroplating workpiece 13 to swing to the right until the dial rod 70 crosses the right-angled end point of the left ends of the third side plate and the fourth side plate, and the dial rod 70 is located below the third side plate. When the electroplating workpiece 13 descends, the third side plate abuts against the dial rod 70, and the dial rod 70 will generate an upward thrust on the third side plate, thereby pushing the electroplating workpiece 13 to rotate clockwise until the dial rod 70 leaves the third side plate and the clamping rod 42 reaches the right-angled end point of the left ends of the third side plate and the fourth side plate. As the electroplating workpiece 13 continuously rises and falls, the electroplating workpiece 13 rotates multiple times, continuously changing the clamping position of the clamping rod 42 on the electroplating workpiece 13.

[0071] As Figure 11 shown in the figure, the blanking module includes a support column 80, an inclined plate 81, a blanking plate 82 and a roller 83.

[0072] A support column 80 is fixedly installed at the bottom of the electroplating bath 11. An inclined plate 81 is fixedly installed near the upper end on the left side of the support column 80. The inclined plate 81 slopes upward gradually from left to right. A blanking plate 82 is fixedly installed near the upper end on the right side of the support column 80. The blanking plate 82 is inclined. The blanking plate 82 slopes downward gradually from left to right, and the blanking plate 82 passes through the discharge port 12. A plurality of rollers 83 are rotatably installed at intervals in the left-right direction on the blanking plate 82. The rollers 83 rotate about an axis extending in the front-rear direction.

[0073] The driving rod 44 finally reaches the conveying section 65. When the left bearing seat 40 and the right bearing seat 50 drive the electroplated workpiece 13 to continue moving to the right, the bottom surface of the electroplated workpiece 13 abuts against the upper surface of the inclined plate 81, so that the bottom of the electroplated workpiece 13 deflects to the left. When the right bearing seat 50 reaches the turning point on the right side of the conveying chain 33, the right bearing seat 50 will first rotate upward, so that the right sliding seat 51 is separated from the electroplated workpiece 13. At the same time, since the electroplated workpiece 13 slopes to the right upward, the electroplated workpiece 13 is separated from the clamping rod 42, and the electroplated workpiece 13 falls onto the blanking plate 82 and is finally conveyed out by the rollers 83.

[0074] The working principle of the present invention is as follows: During operation, the conveying chain 33 drives the left bearing seat 40 and the right bearing seat 50 to rotate counterclockwise. When the left bearing seat 40 and the right bearing seat 50 rotate to the turning point on the left side, the first guide post 43 and the second guide post 53 will abut against the guide frame 24. The first guide post 43 and the second guide post 53 first abut against the vertical section 28 of the guide frame 24, so that the left sliding seat 41 contracts into the left bearing seat 40, the spring is compressed, and the right sliding seat 51 also contracts into the right bearing seat 50 (as Figure 4 shown). The right bearing seat 50 will first rotate downward and enter the arc section 25 after passing through the vertical section 28. At this time, the left bearing seat 40 and the right bearing seat 50 change from being parallel to each other to a V-shaped structure. At this time, the pushing mechanism can push the electroplated workpiece 13 on the loading platform 20 to the right, so that the electroplated workpiece 13 can enter the two conveying channels respectively, and the electroplated workpiece 13 is located on the upper surface of the turning plate 23, and the right end of the electroplated workpiece 13 extends between the left bearing seat 40 and the right bearing seat 50.

[0075] The left bearing seat 40 continues to rotate. The clamping rod 42 on the left sliding seat 41 will insert into the inner side of the electroplated workpiece 13 and abut against the bottom surface of the groove. The left sliding seat 41 abuts against the upper surface of the electroplated workpiece 13. As the left bearing seat 40 rotates, it will push the electroplated workpiece 13 downward and to the right, and the turning plate 23 is forced to rotate downward. Immediately afterwards, both the first guide post 43 and the second guide post 53 reach the arc section 25, and the electroplated workpiece 13 gradually disengages from the turning plate 23 and is placed between the left bearing seat 40 and the right bearing seat 50. Since the right bearing seat 50 is still in an inclined state, the electroplated workpiece 13 will slide downward along the inclined surface of the right bearing seat 50 and is finally blocked by the clamping rod 42. Then the left bearing seat 40 and the right bearing seat 50 continue to rotate, and the first guide post 43 and the second guide post 53 gradually enter the horizontal section 26. At this time, both the left bearing seat 40 and the right bearing seat 50 are in a vertical state, and the electroplated workpiece 13 is completely hung on the clamping rod 42 (as Figure 6 shown). At this time, the bottom surface of the electroplated workpiece 13 is on the right side and abuts against the top block 52, and the clamping rod 42 is located at the inner corner of the electroplated workpiece 13. At this time, the telescopic end of the telescopic plate 45 also inserts into the slot 54.

[0076] During the process of the left bearing seat 40 and the right bearing seat 50 driving the electroplated workpiece 13 to move to the right, the driving rod 44 will gradually abut against the driving frame 61. Thus, when the driving rod 44 gradually passes through the rising section 62, the connecting section 63 and the falling section 64, the driving rod 44 will continuously rise and fall, so that during the process of the left sliding seat 41 and the right sliding seat 51 driving the electroplated workpiece 13 to move to the right, they will continuously rise and fall. The continuous rising and falling of the electroplated workpiece 13 can disturb the electroplating solution in the electroplating tank 11 up and down, making the distribution of metal ions in the upper and lower layers of the electroplating solution more uniform.

[0077] At the same time, during the process of the left bearing seat 40 and the right bearing seat 50 driving the electroplated workpiece 13 to move to the right, the driving rod 44 will gradually abut against the driving frame 61. Thus, when the driving rod 44 gradually passes through the rising section 62, the connecting section 63 and the falling section 64, the driving rod 44 will continuously rise and fall, so that during the process of the left sliding seat 41 and the right sliding seat 51 driving the electroplated workpiece 13 to move to the right, they will continuously rise and fall. The continuous rising and falling of the electroplated workpiece 13 can disturb the electroplating solution in the electroplating tank 11 up and down, making the distribution of metal ions in the upper and lower layers of the electroplating solution more uniform.

[0078] Finally, the driving rod 44 reaches the conveying section 65. When the left bearing seat 40 and the right bearing seat 50 drive the electroplated workpiece 13 to continue moving to the right, the bottom of the electroplated workpiece 13 abuts against the upper surface of the inclined plate 81, so that the bottom of the electroplated workpiece 13 deflects to the left. When the right bearing seat 50 reaches the turning point on the right side of the conveying chain 33, the right bearing seat 50 will first rotate upward, so that the right sliding seat 51 is disengaged from the electroplated workpiece 13. At the same time, since the electroplated workpiece 13 is inclined to the right upward, the electroplated workpiece 13 is disengaged from the clamping rod 42, and the electroplated workpiece 13 falls on the blanking plate 82 and is finally conveyed out by the roller 83.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
