Description

Technical Field

[0001] The present invention relates to the technical field of vehicle positioning, and particularly relates to an electroplating line vehicle traveling and positioning system and method. Background Art

[0002] An electroplating tank is the most basic equipment in electroplating equipment, mainly used for containing solutions. An electroplating vehicle is a transportation tool on an electroplating production line that can ensure multi-station (electroplating tank positions) operation, with vertical and horizontal transportation capabilities. Specifically, the electroplating vehicle transports the products to be electroplated to each electroplating tank through a lifting hanger for electroplating, and then removes and transfers the electroplated items from the electroplating tank. The quality of its design directly determines the electroplating efficiency and electroplating quality of the electroplating line.

[0003] Currently, most positioning devices of electroplating vehicles use radio frequency identification (RFID) positioning technology to achieve positioning. When the electroplating vehicle moves to directly above the electroplating tank, the reader can read the electronic tag card installed above the tank position, thereby controlling the driving motor to stop rotating to achieve positioning. However, after the driving motor stops running, due to inertia, the electroplating vehicle will still continue to move a certain distance, resulting in the electroplating vehicle being unable to accurately align directly above the electroplating tank. Therefore, there are still defects in inaccurate positioning and poor traveling accuracy of the vehicle. Based on this, we propose an electroplating line vehicle traveling and positioning system and method. Summary of the Invention

[0004] The present invention aims to solve the above technical problems and provide an electroplating line vehicle traveling and positioning system and method to achieve precise positioning of the vehicle body, improve the traveling accuracy of the vehicle, and enable the vehicle body to accurately be directly above the electroplating tank.

[0005] To solve the above technical problems, the present invention provides an electroplating line vehicle traveling and positioning system, including a 'C'-shaped workbench, a positioning mechanism and a processor arranged inside the workbench. The processor includes a timing module for monitoring the electroplating time of products. The workbench includes a gantry vehicle body arranged at the top of the workbench and two or more electroplating tanks fixed to the bottom surface of the workbench. The number of the positioning mechanisms is the same as that of the electroplating tanks and their centerlines coincide.

[0006] A traveling track is arranged on the outer wall of the top of the workbench, and the vehicle body is arranged on the inner wall of the traveling track through a traveling driving part.

[0007] The positioning mechanism includes a contact part, an alarm part and an implementation part arranged on opposite side surfaces of the workbench. A traction mechanism is fixed to the top end of the vehicle body.

[0008] Preferably, the contact part includes a support plate located directly below the walking track and fixed to the inner wall of the work frame, a top block inserted into one side of the work frame, a pushing block fixedly connected to one end of the top block, through grooves and sliding grooves respectively arranged on the outer wall of the top of the support plate and the inner wall of the bottom of the work frame, and the outer walls on both sides and the bottom of the pushing block are respectively slidably connected to the inner walls of the through groove and the sliding groove through sliders.

[0009] Preferably, the alarm part is located below the support plate. The alarm part includes a top rod fixed to one side of the pushing block, a pressing plate fixedly connected to one end of the top rod, a rubber block fixed to one side of the pressing plate, a box body fixed to the inner wall of the bottom of the work frame, and a monitoring element fixed to one inner wall of the box body, and the pressing plate forms a sliding fit with the inner wall of the box body.

[0010] Preferably, the implementation part includes a fixed seat fixed to the top surface of the support plate, a liquid cavity in an 'L' shape arranged inside the fixed seat, a piston rod and a piston column respectively inserted into both ends of the liquid cavity, and a limiting block in a 'C' shape fixed to the top end of the piston column, and the outer wall of the piston column forms a sliding fit with the top surface of the fixed seat.

[0011] Preferably, a buffer cavity is arranged inside the fixed seat close to the liquid cavity. One side surfaces close to the top end and the bottom end of the buffer cavity are respectively fixed with a liquid outlet and a liquid return port communicating with the liquid cavity, and one-way valves are arranged on the outer walls of the liquid outlet and the liquid return port.

[0012] Preferably, the same spring is fixedly connected to the opposite side surfaces of the sliding groove and the pushing block.

[0013] Preferably, a warning light with the same number and consistent horizontal position as the electroplating tank is fixedly connected to one side surface of the work frame; a display screen is fixedly installed on one side surface of the work frame through a connecting plate.

[0014] Preferably, the traction mechanism includes a housing fixedly connected to one side surface of the traveling crane body, a lifting motor fixed to the inner wall of the housing, a winding roller rotatably connected to the top end of the traveling crane body, a traction rope arranged on the outer wall of the winding roller, and one end of the winding roller is connected to the output end of the lifting motor through a coupling;

[0015] Guide grooves are arranged on the opposite side surfaces of the traveling crane body. The inner walls of the two guide grooves are slidably connected with the same lifting hanging frame through sliders, and one end of the traction rope is arranged at the top end of the lifting hanging frame.

[0016] Preferably, the walking driving part includes a walking wheel rotatably connected to one side surface of the moving block, and a driving motor fixed to the inner wall of the top of the moving block, and the output end of the driving motor is connected to one end of the walking wheel through a connecting shaft.

[0017] A method for positioning the traveling of an electroplating line traveling crane includes the following steps:

[0018] S1: After fixing the product to be electroplated on the lifting hanger, the traveling driving part controls the traveling body to move within the traveling track.

[0019] S2: During the movement of the traveling body, it contacts with the contact part, causing the pushing block to move backward and push the alarm part to start and send a signal to the processor to control the traveling driving part to stop running.

[0020] S3: The backward movement of the pushing block will also simultaneously push the implementation part to start, so that the limiting block moves upward to semi-surround and hold the traveling wheels of the traveling driving part, for precise positioning of the traveling body.

[0021] S4: The traction mechanism controls the lifting hanger to carry the product down into the electroplating tank for electroplating.

[0022] S5: When the timing module monitors that the preset electroplating time is reached, the processor controls the traction mechanism to start in the reverse direction to pull the product out of the electroplating tank, and then controls the traveling driving part to start again.

[0023] Advantages of the present invention:

[0024] 1. The present invention is provided with a positioning mechanism. During the movement of the traveling body, it contacts with the contact part, causing the pushing block to move backward and push the alarm part to start and send a signal to the processor to control the traveling driving part to stop running. During this period, the backward movement of the pushing block will also simultaneously push the implementation part to start, so that the limiting block moves upward to semi-surround and hold the traveling wheels of the traveling driving part, preventing the traveling body from still moving forward or backward a certain distance under the inertia effect after the driving motor stops working, realizing precise positioning of the traveling body, improving the traveling accuracy of the traveling crane, and enabling the traveling body to be accurately above the electroplating tank.

[0025] 2. When the bottom end of the piston column moves above the liquid outlet, the liquid in the liquid cavity will slowly flow into the buffer cavity from the liquid outlet under the pushing limit of the piston rod for temporary storage, causing the liquid level in the liquid cavity to drop, so as to control the limiting block after limiting the traveling body to move down a certain height under the drive of the piston column, making the limiting block semi-project from the inner wall of the bottom of the traveling track, facilitating the later traveling wheels to cross over.

[0026] 3. When the preset electroplating time is reached, the processor controls the drive motor to start again, so that the traveling body continues to move after rolling over the top of the limiting block. The limiting block presses the liquid in the liquid cavity under the top pressure, causing the liquid to reverse-extrude the piston rod to move backward until the top surface of the limiting block is flush with the inner wall of the bottom of the traveling track. At this time, the liquid in the buffer cavity is pumped back into the liquid cavity from the liquid return port by the backward-moving piston rod; when the piston column presses the liquid in the liquid cavity passively, the spring simultaneously supports the pushing block, thereby enabling the pushing block to quickly reset and making the top block project out of the side surface of the workbench again.

[0027] 4. Start the drive motor to drive the walking wheels to roll in the walking track, thereby driving the moving block to move through the auxiliary track as well, so that the traveling body can be displaced with a stable structure. During the passive lifting and lowering of the lifting hanger, its two ends will contact and impact multiple impact components, and then the excess electroplating solution on the product can quickly fall, reducing the waste of the bath solution.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following further illustrates the present invention with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited do not limit the present invention.

[0036] Refer to Figure 1-6As shown in the figure, an embodiment of the traveling and positioning system of the electroplating line of the present invention includes a jig 1 in a 'C' shape for facilitating electroplating of products, a positioning mechanism and a processor [not shown in the figure] disposed in the jig 1. The processor includes a timing module for monitoring the electroplating time of the products. The jig 1 includes a gantry crane body 2 disposed at the top of the jig 1 for transporting products and a plurality of electroplating tanks 3 fixed to the bottom surface of the jig 1. Preferably, the number of the positioning mechanisms is the same as that of the electroplating tanks 3, and the center lines of the two coincide, so as to accurately control the traveling and positioning of the gantry crane body 2.

[0037] A traveling track 5 is provided on the outer wall of the top of the jig 1, and the gantry crane body 2 is disposed on the inner wall of the traveling track 5 through a traveling driving part.

[0038] Preferably, auxiliary rails 4 are provided on both side surfaces of the jig 1, and a moving block 202 fixed to one side surface near the bottom end of the gantry crane body 2 is slidably connected to the inner wall of the auxiliary rail 4 through a slider, improving the stability of the gantry crane body 2 during movement.

[0039] Further preferably, the traveling driving part includes a traveling wheel 12 rotatably connected to one side surface of the moving block 202 and a driving motor 11 fixed to the inner wall of the top of the moving block 202, and the output end of the driving motor 11 is connected to one end of the traveling wheel 12 through a connecting shaft. Starting the driving motor 11 drives the traveling wheel 12 to roll in the traveling track 5, and then drives the moving block 202 to move through the auxiliary rail 4, so that the gantry crane body 2 is displaced, and the structure is stable.

[0040] As Figure 3-5 shown in the figure, the positioning mechanism includes a contact part, an alarm part and an implementation part for limiting the gantry crane body 2 disposed on opposite side surfaces of the jig 1. The contact part includes a support plate 14 located directly below the traveling track 5 and fixed to the inner wall of the jig 1, a top block 6 inserted into one side surface of the jig 1, a top moving block 19 welded to one end of the top block 6, through grooves 25 and sliding grooves 20 respectively opened on the outer wall of the top of the support plate 14 and the inner wall of the bottom of the jig 1, and the outer walls on both sides and the bottom outer wall of the top moving block 19 are slidably connected to the inner walls of the through groove 25 and the sliding groove 20 through sliders respectively. The gantry crane body 2 moves on the jig 1. When the leg of the gantry crane body 2 moves to the position of the top block 6, that is, directly above a certain electroplating tank 3, one side surface thereof will squeeze the top block 6 to move backward, and then push the top moving block 19 to move backward under the limitation of the through groove 25 and the sliding groove 20 until one end of the top block 6 abuts against one side surface of the gantry crane body 2.

[0041] As Figure 3-5As shown in the figure, the alarm part is located below the support plate 14. The alarm part includes a push rod 21 fixed to one side of the jacking block 19, a pressing plate 22 welded to one end of the push rod 21, a rubber block 23 fixed to one side of the pressing plate 22, a box body 15 fixed to the inner wall of the bottom of the tool rest 1, and a monitoring element 24 fixed to one inner wall of the box body 15. The monitoring element 24 and the driving motor 11 are respectively communicatively connected to the processor. The pressing plate 22 forms a sliding fit with the inner wall of the box body 15. When the jacking block 19 moves backward, the push rod 21 is used to push the pressing plate 22 and the structures thereon to move synchronously in the box body 15. When the rubber block 23 contacts or continuously presses the monitoring element 24, the monitoring element 24 transmits a signal to the processor so that it can control the driving motor 11 to stop working, thereby controlling the traveling body 2 to stop moving.

[0042] Preferably, the monitoring element 24 can be one of a pressure sensor, a collision sensor, etc.

[0043] As Figure 3-6 shown in the figure, the implementation part includes a fixed seat 16 fixed to the top surface of the support plate 14, a liquid cavity 26 in an 'L' shape opened inside the fixed seat 16, a piston rod 13 and a piston column 18 respectively inserted into both ends of the liquid cavity 26, and a limiting block 10 fixed to the top end of the piston column 18 in a 'C' shape. The outer wall of the piston column 18 forms a sliding fit with the top surface of the fixed seat 16. The piston rod 13 will also move backward in the liquid cavity 26 under the push of the jacking block 19 to squeeze the liquid inside, so that the piston column 18 drives the limiting block 10 to move upward under the push of the liquid, thereby semi-surroundingly clamping the traveling wheels 12 entering the top range of the limiting block 10 to prevent the traveling body 2 from still moving forward or backward a certain distance under the action of inertia after the driving motor 11 stops working, realizing the precise positioning of the traveling of the traveling body 2.

[0044] As a supplement, as Figure 6 shown in the figure, a buffer cavity 27 is opened inside the fixed seat 16 close to the liquid cavity 26. One side surface near the top end and the bottom end of the buffer cavity 27 is respectively fixed with a liquid outlet 29 and a liquid return port 28 communicating with the liquid cavity 26, and one-way valves are arranged on the outer walls of the liquid outlet 29 and the liquid return port 28. When the bottom end of the piston column 18 moves above the liquid outlet 29, the liquid in the liquid cavity 26 will slowly flow into the buffer cavity 27 from the liquid outlet 29 and be temporarily stored under the pushing and limiting of the piston rod 13, so that the liquid level in the liquid cavity 26 drops, so as to control the limiting block 10 after limiting the traveling body 2 to move downward a certain height under the drive of the piston column 18, so that the limiting block 10 protrudes semi-convexly from the inner wall of the bottom of the traveling track 5, which is convenient for the traveling wheels 12 to cross later. Here, since the piston rod 13 is still held, the liquid in the buffer cavity 27 will not flow back from the liquid return port 28.

[0045] Further, the opposite side surfaces of the sliding groove 20 and the pushing block 19 are welded with the same spring 17; when the preset electroplating time is reached, the processor controls the driving motor 11 to start again, so that the traveling body 2 continues to move forward after rolling over the top of the limiting block 10, and the limiting block 10 presses the liquid in the liquid chamber 26 under the top pressure, causing the liquid to back-extrude the piston rod 13 to move backward until the top surface of the limiting block 10 is horizontally aligned with the bottom inner wall of the traveling track 5. At this time, the liquid in the buffer chamber 27 flows back into the liquid chamber 26 again from the liquid return port 28 under the pumping action of the backward-moving piston rod 13; when the piston column 18 presses the liquid in the liquid chamber 26 passively, the spring 17 simultaneously supports the pushing block 19, thereby enabling the pushing block 19 to quickly reset, so that the top block 6 projects out of the side surface of the tool rest 1 again.

[0046] Furthermore, on one side surface of the tool rest 1, there are fixed connection with the same number of indicating lights 9 as the electroplating tanks 3 and at the same horizontal position, which are used to prompt the working positions of the electroplating tanks 3 being used at the current time. The indicating lights 9 are communicatively connected with the processor; when the monitoring element 24 at a certain working position is started, the processor controls the corresponding indicating light 9 to light up. On one side surface of the tool rest 1, there is a display screen 8 fixed through a connecting plate, and the display screen 8 is communicatively connected with the processor; the processor converts the obtained signal and sends it to the display screen 8 for display, so that people can understand the usage situation of all working positions on the tool rest 1.

[0047] To realize the movement of the traveling body 2; as Figure 1-2 shown, a traction mechanism is fixed at the top of the traveling body 2. The traction mechanism includes a housing fixed to one side surface of the traveling body 2 by bolts, a lifting motor 201 fixed to the inner wall of the housing, a winding roller rotatably connected to the top of the traveling body 2, and a traction rope wound around the outer wall of the winding roller. One end of the winding roller is connected to the output end of the lifting motor 201 through a coupling; starting the lifting motor 201 drives the winding roller to rotate, thereby taking in and paying out the traction rope.

[0048] Preferably, the lifting hanging bracket 203 refers to the existing technology and will not be elaborated here.

[0049] Further, guiding grooves 204 are respectively opened on the opposite side surfaces of the traveling body 2. The inner walls of the two guiding grooves 204 are slidably connected with the same lifting hanging bracket 203 for clamping the product to be electroplated through sliders, and one end of the traction rope is tied to the top of the lifting hanging bracket 203; the traction rope pulls the lifting hanging bracket 203 to lift and lower in the guiding groove 204, so as to perform the lowering and lifting actions on the product.

[0050] To make the excess electroplating liquid on the product drip quickly; as Figure 1As shown, on both sides of the traveling body 2 at both ends of the lifting hanger 203, multiple sets of impact components 7 are fixedly arranged in a vertical column. The impact component 7 is composed of a rubber support arm and a gravity ball fixed at one end of the rubber support arm; during the passive lifting of the lifting hanger 203, its two ends will contact and impact multiple sets of impact components 7, thereby enabling the excess electroplating solution on the product to fall rapidly, reducing the waste of the bath solution.

[0051] When this embodiment is in use, after placing the product to be electroplated on the lifting hanger 203 and fixing it, the driving motor 11 is started to drive the traveling wheels 12 to roll in the traveling track 5, thereby driving the moving block 202 to move through the auxiliary track 4 as well, so that the traveling body 2 undergoes displacement.

[0052] When the leg of the traveling body 2 moves to the position of the top block 6, that is, directly above a certain electroplating bath 3, one side of it will squeeze the top block 6 to move backward, thereby pushing the jacking block 19 to move backward under the limitation of the through slot 25 and the sliding slot 20 until one end of the top block 6 abuts against one side of the traveling body 2. During this period, the backward movement of the jacking block 19 will push the extrusion plate 22 and its upper structure to move synchronously in the box body 15 through the top rod 21. When the rubber block 23 contacts or continuously squeezes the monitoring element 24, the monitoring element 24 transmits a signal to the processor so that it can control the driving motor 11 to stop working, thereby controlling the traveling body 2 to stop moving. At the same time, the piston rod 13 will also move backward in the liquid cavity 26 under the push of the jacking block 19 to squeeze the liquid therein, so that the piston column 18 drives the limiting block 10 to move upward under the pushing of the liquid, thereby semi-surroundingly clamping the traveling wheels 12 entering the top range of the limiting block 10 to prevent the traveling body 2 from still moving forward or backward a certain distance under the inertia effect after the driving motor 11 stops working; when the bottom end of the piston column 18 moves above the liquid outlet 29, the liquid in the liquid cavity 26 will slowly flow into the buffer cavity 27 through the liquid outlet 29 under the pushing and limiting of the piston rod 13 for temporary storage, causing the liquid level in the liquid cavity 26 to drop, so as to control the limiting block 10 to move downward a certain height under the drive of the piston column 18 after limiting the traveling body 2, so that the limiting block 10 protrudes semi-convexly from the inner wall of the bottom of the traveling track 5. After the traveling body 2 stops moving, the lifting motor 201 is started to drive the winding roller to rotate, and then the lifting hanger 203 is wound and unwound through the traction rope to control the lowering and pulling actions of the product; and the processor controls the corresponding indicator light 9 to light up so that people can observe the occupancy situation of the work station.

[0053] When the timing module monitors that the preset electroplating time is reached, the processor controls the traction mechanism to start in reverse, pulls the product up and out of the electroplating tank 3, and then controls the driving motor 11 to start again, so that the traveling body 2 continues to move after rolling over the top of the limit block 10. Under the heavy pressure at the top, the limit block 10 presses down the liquid in the liquid chamber 26, causing the liquid to squeeze the piston rod 13 backward until the top surface of the limit block 10 is flush with the bottom inner wall of the traveling track 5. At this time, the liquid in the buffer chamber 27 flows back into the liquid chamber 26 again from the liquid return port 28 under the pumping of the backward moving piston rod 13; when the piston column 18 presses down the liquid in the liquid chamber 26 passively, the spring 17 simultaneously supports the top block 19, so that the top block 19 quickly resets, and the top block 6 protrudes from one side of the tool rest 1 again. During the stop of the traveling body 2, the processor converts the obtained signal and sends it to the display screen 8 for display, so that people can understand the usage of all workstations on the tool rest 1.

[0054] Embodiment 2:

[0055] An electroplating line traveling vehicle traveling and positioning method, as Figure 1-6 shown, includes the following steps:

[0056] S1: After fixing the product to be electroplated on the lifting hanger 203, the traveling body 2 is controlled by the traveling drive unit to move in the traveling track 5;

[0057] S2: During the movement of the traveling body 2, it contacts the contact part, causing the top block 19 to move backward and push the alarm part to start and send a signal to the processor to control the traveling drive unit to stop running;

[0058] S3: When the top block 19 moves backward, it also simultaneously pushes the implementation part to start, so that the limit block 10 moves up to semi-surround and hold the traveling wheel 12 of the traveling drive unit to accurately position the traveling body 2;

[0059] S4: The lifting hanger 203 is controlled by the traction mechanism to carry the product down into the electroplating tank 3 for electroplating;

[0060] S5: When the timing module monitors that the preset electroplating time is reached, the processor controls the traction mechanism to start in reverse to pull the product out of the electroplating tank 3, and then controls the traveling drive unit to start again.

[0061] When this embodiment is used, the operation is simple, and the purpose of accurate positioning during the traveling of the traveling body 2 is achieved.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
