DETAILED DESCRIPTION

[0029] To facilitate understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the present disclosure.

[0030] See attached Figures 1 to 10 As shown, in this embodiment, a top row system for aluminum surface treatment includes a clamping mechanism 1, two sets of grinding mechanisms 2, an upper positioning mechanism 3, and a lower positioning mechanism 4 provided on a bracket. The clamping mechanism 1 is used for clamping and opening operations; the two sets of grinding mechanisms 2 are arranged adjacent to each other above the clamping mechanism 1 and are used to grind and polish the surface of the conductive rod 100; the upper positioning mechanism 3 is arranged adjacent to the upper position of the grinding mechanism 2 and is used to position the conductive rod 100 upward; the lower positioning mechanism 4 is arranged adjacent to the lower position of the clamping mechanism 1 and is used to position the conductive rod 100 downward. Through the mutual cooperation of the above-mentioned various mechanisms, the positioning and grinding and polishing operations of the conductive rod 100 are completed, and the aluminum profile is clamped to the conductive rod 100.

[0031] See attached Figure 2-4As shown, in this embodiment, the clamping mechanism 1 includes a clamping machine base 11, a track flap 12, a clamping slide 13, an intermediate flap 15, a main horizontal drive unit 16, a main vertical drive unit 17, an opening unit 14, an opening plate 18, a clamping telescopic member 123 and a reset elastic member 124, wherein a vertically arranged vertical slide rail is arranged between the intermediate flap 15 and the clamping machine base 11, that is, the track of the vertical slide rail here is installed on the clamping machine base 11 and the slider of the vertical slide rail is installed on the intermediate flap 15, thereby realizing that the intermediate flap 15 can slide vertically relative to the clamping machine base 11; a horizontally arranged horizontal slide rail is arranged between the intermediate flap 15 and the track flap 12, that is, the track of the horizontal slide rail here is installed on the intermediate flap 15 and the slider of the horizontal slide rail is installed on the track flap 12, thereby realizing that the track flap 12 can slide horizontally relative to the intermediate flap 15. Secondly, the main horizontal driving unit 16 acts on the track flap 12 to slide horizontally; the main vertical driving unit 17 acts on the track flap 12 to slide vertically.

[0032] Specifically, the main horizontal drive unit 16 includes a horizontal drive connecting rod 162 and a horizontal drive cam 161 that can rotate on a fixed axis, wherein the front end of the horizontal drive is movably connected to the vertical sliding hole 121 pre-opened in the track flap 12, and the tail end of the horizontal drive connecting rod 162 is movably connected to the horizontal drive cam 161; the horizontal drive cam 161 is rotatably installed on the clamping machine base 11.

[0033] Specifically, the main vertical drive unit 17 includes a vertical drive link 172 and a vertical drive cam 171 that can rotate on a fixed axis, wherein the upper end of the vertical drive link 172 is movably connected to the transverse sliding hole 122 pre-opened in the track flap 12, and the lower end of the vertical drive link 172 is movably connected to the vertical drive cam 171; the vertical drive cam 171 is rotatably installed on the clamping machine base 11.

[0034] Furthermore, the horizontal drive link 162 and the vertical drive link 172 are both mounted on the clamping machine base 11 via limit sliders. As a result, the horizontal drive link 162 can only move horizontally in the front-to-back direction, and the vertical drive link 172 can only move vertically in the up-down direction. Furthermore, by providing a vertical slide hole 121 for the movable connection of the front end of the horizontal drive, and a transverse slide hole 122 for the sliding connection of the upper end of the vertical drive link 172, the main vertical drive unit 17 and the main vertical drive unit 17 can operate independently or simultaneously without interfering with each other.

[0035] Therefore, with the help of the rotational power of the horizontal driving cam 161 and the vertical driving cam 171, the track flap 12 is driven to slide horizontally and / or vertically through the horizontal driving link 162 and the vertical driving link 172 respectively.

[0036] In this embodiment, the horizontal drive cam 161 and the vertical drive cam 171 are driven to rotate synchronously by the same drive motor, that is, a synchronous belt (which can be in the form of a belt, chain, etc.) circulates through the output shaft of the drive motor, the shaft end of the horizontal drive cam 161 and the shaft end of the vertical drive cam 171 in sequence, thereby realizing the horizontal and vertical sliding of the track flap 12 at the same time.

[0037] In this embodiment, those skilled in the art can set the diameter, width, shape and other parameters of the horizontal drive cam 161 and the vertical drive cam 171 according to the actual production action requirements, so as to realize the action trajectory required by the track flap 12. No limitation is made here, and a derivative technical solution can be adopted.

[0038] In this embodiment, a transverse slide rail is arranged between the clamping slide 13 and the track flap 12, that is, the track of the transverse slide rail is installed on the track flap 12 and the slider of the transverse slide rail is installed on the clamping slide 13. Secondly, the clamping telescopic member 123 and the reset elastic member 124 are provided on the track flap 12, wherein the telescopic end of the clamping telescopic member 123 contacts the tail end of the clamping slide 13 to drive the clamping slide 13 to slide horizontally forward; the reset elastic member 124 acts on the front end of the clamping slide 13 to drive the clamping slide 13 to slide horizontally backward. Specifically, when the telescopic end of the clamping telescopic member 123 extends forward, it gradually contacts the clamping slide 13 to slide horizontally forward, and at the same time, the reset elastic member 124 is compressed to store energy; and when the telescopic end of the clamping telescopic member 123 retracts backward, the reset elastic member 124 releases elastic kinetic energy to drive the clamping slide 13 to slide horizontally backward. Realized thus that the opening slide 13 relative track flaps 12 can be done horizontal sliding. In addition, the opening slide 13 can also be done vertically and horizontally with the track flap 12 synchronously.

[0039] Furthermore, the above-mentioned clamping telescopic member 123 is preferably a telescopic cylinder, and the reset elastic member 124 is preferably a spring member, wherein the two ends of the spring member are respectively connected to the front end of the clamping slide 13 and the track flap 12.

[0040] In this embodiment, the opening unit 14 comprises a push rod 141, two opening connecting plates 142, and two opening pins 143 positioned vertically at the front ends of the two opening connecting plates 142. The rear ends of the two opening connecting plates 142 are hingedly connected to the front end of the push rod 141, which is fixedly connected to the opening slide 13. The two opening pins 143 are designed to be inserted into the opening and closing control position of the clamp. When the opening slide 13 moves forward, the push rod 141 and the two opening connecting plates 142 drive the two opening pins 143 outward, overcoming the elastic force of the clamp and opening the clamp. Conversely, the elastic force of the clamp and the elastic force of the return spring 124 cause the opening slide 13 to move backward.

[0041] See attached Figure 5 As shown, in this embodiment, it also includes an upper clamping mechanism 5 arranged adjacent to the upper part of the clamping mechanism 1. The upper clamping mechanism 5 includes an upper clamping conveying channel 51 and an upper clamping conveying track 52. The upper clamping conveying channel 51 is used to carry the clamps. The upper clamping conveying channel 51 is provided with a clamping outlet, and the clamping outlet is relatively located above the clamping unit 14, so that the clamping unit 14 can perform clamping and unclamping operations on the clamps transported to the clamping outlet. The upper clamping conveying track 52 is arranged adjacent to the upper clamping conveying channel 51. The upper clamping conveying track 52 is provided with a number of upper clamping shifting blocks 521 arranged at equal intervals. With the directional circulation action of the upper clamping conveying track 52, each upper clamping shifting block 521 cooperates with the upper clamping conveying channel 51 to push each clamp forward in the direction of the clamping outlet in turn, so as to realize the continuous material supply function of the clamps.

[0042] Specifically, the upper clamping conveyor belt 52 is driven by a motor in conjunction with a transmission gear.

[0043] In this embodiment, the opening plate 18 can slide vertically relative to the track flap 12, wherein a vertical slide rail is arranged between the opening plate 18 and the track flap 12 of this embodiment, wherein the guide rail of the vertical slide rail is installed on the track flap 12 and the slider of the vertical slide rail is connected to the opening plate 18. Secondly, an obliquely arranged oblique sliding hole 181 is provided on the opening plate 18, and an opening pulley 131 movably connected to the oblique sliding hole 181 is provided on the clamping slide 13. Therefore, the oblique sliding hole 181 is used to slide relative to the opening pulley 131, so that the oblique sliding hole 181 is used to simultaneously limit the forward and backward sliding distance of the clamping slide 13 relative to the track movable plate 12 and the forward and backward movement distance of the push rod 141, thereby limiting the opening and closing angle of the two clamping connecting plates 142, and finally realizing the control of the opening size of the two clamping needles 143, that is, the longer the relative sliding distance of the opening pulley 131 provided by the oblique sliding hole 181 is, the greater the opening of the two clamping needles 143; conversely, the shorter the relative sliding distance of the opening pulley 131 provided by the oblique sliding hole 181 is, the smaller the opening of the two clamping needles 143 is.

[0044] To facilitate understanding of the above-mentioned clamping mechanism 1 and clamping mechanism 5, the following explanations are given in conjunction with their specific working principles.

[0045] During operation, the main horizontal drive unit 16 and the main vertical drive unit 17 first drive the clamping slide 13 and the track flap 12 to move synchronously, so that the two clamping pins 143 of the clamping unit 14 are aligned with the clamp located at the clamp outlet of the upper clamp conveying channel 51. Subsequently, the main vertical drive unit 17 drives the clamping slide 13 and the track flap 12 to move upward synchronously, so that the two clamping pins 143 of the clamping unit 14 are inserted into the opening and closing control position of the clamp. Next, the extending action of the clamping telescopic member 123 drives the clamping slide 13 to slide forward so that the two clamping needles 143 can open the clamp. Finally, the main horizontal drive unit 16 and the main vertical drive unit 17 drive the clamping slide 13 and the track flap 12 to move synchronously. After the clamp moves to the predetermined position, the retracting action of the clamping telescopic member 123 and the elastic action of the reset elastic member 124 make the two clamping needles 143 no longer support the clamp, so that the clamp is closed to clamp the aluminum material on the conductive rod 100. Finally, each driving element is reset to make the two clamping needles 143 disengage from the clamp to complete a single clamping operation.

[0046] By repeating the above actions and cooperating with the clamping mechanism 5 to continuously feed the clamp, the continuous clamping operation of the clamp is achieved.

[0047] See attached Figure 6 and 7 As shown, in this embodiment, two sets of grinding mechanisms 2 are located on the left and right sides of the conductive rod 100. Each set of grinding mechanisms 2 includes a fixed plate 21, a mounting plate 22, a movable plate 23, a driving wheel 24, a driven wheel 25, and a movable wheel 26. In this embodiment, a grinding transverse slide rail is provided between the fixed plate 21 and the mounting plate 22. That is, the track of the grinding transverse slide rail extends horizontally along the left and right directions and is arranged on the fixed plate 21. The slider of the grinding transverse slide rail is connected to the mounting plate 22. Secondly, the fixed plate 21 is provided with a grinding transverse drive unit 201 for driving the mounting plate 22 to slide horizontally. That is, the grinding transverse drive unit 201 is preferably a telescopic cylinder, the telescopic end of which is connected to the mounting plate 22. Thus, under the drive of the grinding transverse drive unit 201, the mounting plate 22 can slide horizontally relative to the fixed plate 21.

[0048] In this embodiment, the driving wheel 24 and the driven wheel 25 are both rotatably connected to the mounting plate 22, wherein the driven wheel 25 is located at the front end of the mounting plate 22. In addition, the rotation axes of the driving wheel 24 and the driven wheel 25 are both arranged vertically.

[0049] In this embodiment, the movable plate 23 is hinged to the mounting plate 22 via a vertical axis, allowing the movable plate 23 to swing horizontally relative to the mounting plate 22. Specifically, a polishing telescopic member 202 is disposed between the movable plate 23 and the mounting plate 22. The rear end of the polishing telescopic member 202 is hinged to the mounting plate 22, and its telescopic end is hinged to the movable plate 23. The telescopic movement of the polishing telescopic member 202 is adjusted to drive the movable wheel 26 to swing horizontally. Thus, when the telescopic end of the polishing telescopic member 202 is extended, the movable plate 23 is driven to swing horizontally outward relative to the mounting plate 22; conversely, when the telescopic end of the polishing telescopic member 202 is extended, the movable plate 23 is driven to swing horizontally inward relative to the mounting plate 22.

[0050] In this embodiment, the movable wheel 26 is adjustably and movably connected to the movable plate 23 so that the movable wheel 26 can swing up and down relative to the movable plate 23. Specifically, the movable wheel 26 is connected to the movable plate 23 via a hinge assembly 27. The hinge assembly 27 includes an adjusting hinge and an adjusting bolt. The rotating axis of the adjusting hinge is arranged transversely. The first leaf of the adjusting hinge is fixedly connected to the movable plate 23, and the second leaf is rotatably connected to the movable wheel 26. The end of the adjusting bolt vertically penetrates the movable plate 23 and contacts the second leaf of the adjusting hinge. The movable wheel 26 is driven to swing up and down by turning the adjusting bolt. Thus, when the adjusting bolt is turned upward, the adjusting bolt contacts the second leaf and gradually swings upward about the rotating axis of the adjusting hinge, thereby causing the movable wheel 26 to swing upward synchronously. Conversely, when the adjusting bolt is turned downward, the second leaf gradually swings downward about the rotating axis of the adjusting hinge, thereby causing the movable wheel 26 to swing downward synchronously.

[0051] In addition, the driving wheel 24, the driven wheel 25 and the movable wheel 26 are sequentially circulated with a sanding belt 28, and a sanding drive motor is arranged on the mounting plate 22 to drive the driving wheel 24 to rotate. Under the power input of the sanding drive motor, the driving wheel 24, the driven wheel 25 and the movable wheel 26 jointly drive the sanding belt 28 to rotate in a circular motion.

[0052] Furthermore, the movable plate 23 of this embodiment is hinged to the front end position of the mounting plate 22, so that the movable wheel 26 is relatively located at the front end position of the mounting plate 22, so that the sanding belt 28 section between the movable wheel 26 and the driven wheel 25 is used for grinding contact with the conductive rod 100.

[0053] In summary, the angle of the movable wheel 26 relative to the movable plate 23 is controlled by utilizing the adjustment function of the hinge assembly 27, which is mainly used to adjust the grinding angle of the sanding belt 28 section between the movable wheel 26 and the driven wheel 25; and the telescopic function of the grinding telescopic part 202 is used to control the angle between the movable plate 23 and the mounting plate 22, which is mainly used to adjust the tension of the sanding belt 28.

[0054] To facilitate understanding of the above-mentioned grinding equipment, the following is an explanation based on its specific working principle.

[0055] During operation, the position of the mounting plate 22 is first adjusted by the grinding transverse drive unit 201, so that the two grinding mechanisms 2 are adjusted to the appropriate position, so that the section of the sanding belt 28 between the movable wheel 26 and the driven wheel 25 contacts the conductive rod 100. Subsequently, the tension and grinding angle of the sanding belt 28 are adjusted by adjusting the grinding telescopic member 202 and the adjusting bolt. Finally, the sanding drive motor drives the sanding belts 28 of the two grinding mechanisms 2 to simultaneously grind and polish both sides of the conductive rod 100.

[0056] Thus, the conductive rod 100 is surface treated by two sets of grinding mechanisms 2 to remove the insulating oxide layer on the surface of the conductive rod 100, so that the aluminum profile fixed on the conductive rod 100 by the clamp can maintain electrical contact, so that the downstream station can perform surface treatment processes such as aluminum oxidation and electroplating on the aluminum profile.

[0057] Furthermore, the above-mentioned polishing telescopic member 202 is preferably a telescopic cylinder.

[0058] See attached Figure 8 As shown, in this embodiment, the upper positioning mechanism 3 includes a positioning base plate 31, a positioning swing plate 32, a rear positioning wheel 33, a front positioning wheel 35, and two side positioning wheels 34. The rear positioning wheel 33 is fixedly mounted on the positioning base plate 31. Specifically, it extends horizontally from side to side, and its ends are fixedly mounted to the top surface of the positioning base plate 31 via bearing blocks. The two side positioning wheels 34 are movably mounted on either side of the positioning base plate 31 and are each capable of laterally moving relative to the positioning base plate 31. The side positioning wheels 34 extend horizontally from side to side. Side positioning wheels 314 are provided on either side of the positioning base plate 31. These two positioning wheels 314 are connected to their respective telescopic ends. Specifically, the telescopic ends of the side positioning wheels 314 are rotationally connected to the positioning wheels via bearing blocks. The telescopic movement of the side positioning wheels 314 drives the positioning wheels to translate horizontally from side to side. The positioning swing plate 32 is hinged to the positioning base plate 31 through a vertical axis so that the positioning swing plate 32 can swing horizontally relative to the positioning base plate 31. The front positioning wheel 35 is fixedly installed on the positioning swing plate 32. Specifically, the front positioning wheel 35 installed on the positioning swing plate 32 is located in front of the rear positioning wheel 33, and a front positioning telescopic member 321 is arranged between the positioning base plate 31 and the positioning swing plate 32. The tail end of the front positioning telescopic member 321 is hinged to the positioning fixed plate and its telescopic end is hinged to the positioning swing phase. The positioning swing plate 32 is driven to swing horizontally by adjusting the telescopic action of the front positioning telescopic member 321.

[0059] Furthermore, the positioning base plate 31 is provided with an upper positioning drive unit 311 for driving it to move in the front-to-back direction, wherein the telescopic end of the upper positioning drive unit 311 is connected to the positioning base plate 31, and the telescopic action of the upper positioning drive unit 311 drives the positioning base plate 31 to move horizontally in the front-to-back direction, thereby driving the rear positioning wheel 33, the front positioning wheel 35 and the two side positioning wheels 34 to move horizontally forward and backward synchronously.

[0060] Furthermore, in order to avoid collision and interference between the side positioning wheels 34 and the rear positioning wheels 33 or the front positioning wheels 35 , the side positioning wheels 34 and the rear positioning wheels 33 or the front positioning wheels 35 in this embodiment are arranged at different heights.

[0061] For ease of understanding, the working principle of the positioning mechanism 3 is further explained below in conjunction with the positioning mechanism 3.

[0062] During operation, the front positioning telescopic member 321 extends, driving the positioning swing plate 32 and the front positioning wheel 35 to swing outward in a synchronous horizontal direction. Subsequently, the upper positioning drive unit 311 extends, driving the positioning base plate 31 to move forward horizontally until the front positioning wheel 35 contacts the conductive rod 100. Next, the two sets of side positioning wheels 314 extend, driving the two side positioning wheels 34 toward each other, and the front positioning telescopic member 321 retracts, driving the positioning swing plate 32 and the front positioning wheel 35 to swing inward in a synchronous horizontal direction until both the two side positioning wheels 34 and the front positioning wheel 35 contact the conductive rod 100. At this point, the interference of the rear positioning wheel 33, the front positioning wheel 35, and the two side positioning wheels 34 collectively limits the four degrees of freedom of the conductive rod 100: front, rear, left, and right, thereby completing the upper positioning of the conductive rod 100.

[0063] See attached Figure 9 As shown, in this embodiment, the lower positioning mechanism 4 includes a lower positioning seat 41, a first positioning wheel 42, a second positioning wheel 43, and a lower positioning telescopic member 44 mounted on the lower positioning seat 41. The first positioning wheel 42 is rotatably connected to the lower positioning seat 41, and the telescopic end of the lower positioning telescopic member 44 is rotatably connected to the second positioning wheel 43. The first positioning wheel 42 and the second positioning wheel 43 are located in the left and right horizontal directions. The telescopic action of the lower positioning telescopic member 44 drives the second positioning wheel 43 to move closer to or away from the first positioning wheel 42. Secondly, the circumferential surfaces of the first positioning wheel 42 and the second positioning wheel 43 are both formed with an annular groove for the conductive rod 100 to pass through.

[0064] Furthermore, the upper positioning drive unit 311 , the side positioning wheels 314 , the lower positioning telescopic member 44 , and the front positioning telescopic member 321 are preferably telescopic cylinders.

[0065] For ease of understanding, further explanation is given below in conjunction with the specific lower positioning mechanism 4 and its working principle.

[0066] During operation, the conductive rod 100 first passes through the gap between the first positioning wheel 42 and the second positioning wheel 43, and the annular groove of the first positioning wheel 42 cooperates with the conductive rod 100. Then, the lower positioning telescopic member 44 extends, driving the second positioning wheel 43 to move forward toward the first positioning wheel 42, so that the annular grooves of the first positioning wheel 42 and the second positioning wheel 43 jointly restrict the conductive rod 100, thus completing the lower positioning of the conductive rod 100. The first positioning wheel 42 and the second positioning wheel 43 jointly limit the four degrees of freedom of the conductive rod 100: front, back, left, and right.

[0067] In this embodiment, the lower positioning mechanism 4 always maintains a limited position until the conductive rod 100 completes the upper row operation of the aluminum profile and completely leaves the lower positioning mechanism 4. Then, the lower positioning telescopic member 44 retracts and returns to its original position, so that the second positioning wheel 43 moves away from the first positioning wheel 42, waiting for the next group of conductive rods 100 to be operated in the upper row to arrive in place. The upper positioning mechanism 3 plays a more pre-positioning role. Specifically, when the conductive rod 100 reaches the predetermined position of the upper row system, it is driven by a pre-set lifting pulley to gradually move from top to bottom. At this time, the upper positioning mechanism 3 pre-acts to perform an upper positioning operation on the conductive rod 100. After being positioned by the upper positioning mechanism 3, the conductive rod 100 can more accurately pass between the first positioning wheel 42 and the second positioning wheel 43 of the lower positioning mechanism 4. Then, the lower positioning mechanism 4 is activated to simultaneously perform a lower positioning operation on the conductive rod 100. After the conductive rod 100 descends to a predetermined height, the upper positioning mechanism 3 resets and disengages from the conductive rod 100, maintaining only the lower positioning operation of the lower positioning mechanism 4. The clamping mechanism 1 and the upper clamping mechanism 5 are then activated to clamp the pliers. Furthermore, after the conductive rod 100 is pre-positioned by the upper positioning mechanism 3 and continues to move downward, the polishing mechanism 2 is activated to polish the surface of the conductive rod 100. Once the conductive rod 100 has been lowered to its designated position, the polishing mechanism 2 resets and disengages from the conductive rod 100, effectively preventing interference between the polishing mechanism 2 and the upper positioning mechanism 3 during the clamping operation.
