Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile interior part processing, in particular to an automatic overturning type automobile interior part chrome plating equipment, and also relates to a chrome plating process. BACKGROUND

[0002] In the field of automobile manufacturing, the chrome plating treatment of automobile interior parts is one of the key processes for improving the appearance and durability of products. The traditional automobile interior part chrome plating equipment has many limitations in actual use. On the one hand, the existing chrome plating equipment often needs manual overturning of the interior part when double-sided chrome plating is performed, which not only has high labor intensity, but also manual operation can easily cause the interior part to shift or collide during overturning, affecting the uniformity and integrity of the chrome plating, and thus reducing product quality.

[0003] In the prior art, a chemical chrome plating device for automobile decoration part electroplating processing is disclosed in Chinese Utility Model Patent No. CN218823182U, which is provided with a chrome plating box, a reduction motor, a rotating rod, a support net plate, a connecting sleeve and an automobile decoration part body. By controlling the reduction motor, the movable plate can be conveniently rotated, which facilitates the overturning of the automobile decoration part body and the chrome plating of the other side of the automobile decoration part body, reducing the workload of the workers and having high practicality. Moreover, a support rod is installed on the movable plate, and the automobile interior part can be placed outside the support rod for fixation.

[0004] The fixation of the automobile interior part by the support rod in the above-mentioned prior art relies on the contact limiting after manual placement. When the rotating angle of the movable plate exceeds 90 degrees, the automobile interior part is only supported by the contact of the support rod, lacking a three-dimensional limiting structure, and under the action of gravity, there is a risk of sliding downward.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means and specific purposes and functions achieved by the application, the application will be further described in detail below with reference to the drawings and specific embodiments.

[0037] REFERENCE Figures 1 to 10The device is shown: a kind of automatic turnover type automotive interior chrome plating equipment, including chrome plating box 1, turnover mechanism 2 and support structure 3;Turnover mechanism 2 includes turnover frame 21 and is used to drive the speed reducer motor 22 of turnover frame 21 turnover, both ends of turnover frame 21 are along the central axis of turnover frame 21 It is provided with rotating shaft 211, rotating shaft 211 is connected with chrome plating box 1;Support structure 3 includes two support assemblies 31 and two separation structures 32, two support assemblies 31 are respectively arranged in the two sides of turnover frame 21, support assembly 31 includes mounting bracket 311, support net 312, multiple magnetic attraction components 313 and limiting rod 314, mounting bracket 311 is parallel to turnover frame 21, support net 312 is arranged on mounting bracket 311, multiple magnetic attraction components 313 are arranged on support net 312, limiting rod 314 has multiple, limiting rod 314 uses metal material that can be adsorbed on support net 312 by magnetic attraction component 313, two separation structures 32 are respectively arranged in the two ends of turnover frame 21, separation structure 32 is connected with the mounting bracket 311 in two support assemblies 31, separation structure 32 is translated along the direction parallel to the central axis of turnover frame 21 by driving mounting bracket 311, to actively adjust the distance between two mounting bracket 311.

[0038] Before the chromium plating work of the automotive interior part is carried out, the turnover frame 21 in the automatic turnover type chromium plating equipment is horizontally placed, and the upper and lower sides of the support net 312 also remain horizontal. The worker first places the automotive interior part on the lower side of the support net 312. In order to prevent the automotive interior part from being displaced in the subsequent operation, a plurality of limiting rods 314 are vertically placed around the automotive interior part. Since the limiting rods 314 are made of a metal material that can be attracted by the magnetic attraction assembly 313, the limiting rods 314 are fixed on the support net 312 under the action of the attraction force of the magnetic attraction assembly 313 on the support net 312 after being placed. Subsequently, the separation structure 32 drives the two support nets 312 to move close to each other. At this time, the magnetic attraction assembly 313 located on the upper side of the support net 312 plays a role to generate an attraction force on the limiting rod 314, while the magnetic attraction assembly 313 located on the lower side of the support net 312 stops exerting an attraction force on the limiting rod 314, so that the limiting rod 314 is attracted from the lower side of the support net 312 to the upper side of the support net 312. Therefore, the upper side of the support net 312 drives the limiting rod 314 to separate from the automotive interior part, effectively avoiding the problem that the contact part between the automotive interior part and the limiting rod 314 cannot be electroplated due to shielding. Then, the equipment is started to electroplate the surface of one side of the automotive interior part. When the electroplating of one side is completed, the separation structure 32 is controlled again to move the two support nets 312 close to each other, and the plurality of limiting rods 314 are repositioned around the automotive interior part. Subsequently, the deceleration motor 22 drives the turnover frame 21 to rotate around the axis line of the rotation shaft 211, so as to realize the position exchange of the two support nets 312. After the position exchange, the newly located upper side of the support net 312 separates the limiting rod 314 from the automotive interior part by generating an attraction force on the limiting rod 314 through the magnetic attraction assembly 313, and then electroplates the surface of the other side of the automotive interior part. In the entire turnover process, the automotive interior part is constrained in the three-dimensional space formed by the plurality of limiting rods 314, and has no displacement risk under the action of gravity, so as to ensure that the turned automotive interior part can fully contact with the electroplating liquid and ensure the chromium plating effect.

[0039] Referring to Figure 3 and Figure 4 As shown: The support net 312 is provided with a plurality of installation warehouses 3121 for installing the magnetic attraction assembly 313. The middle part of the installation warehouse 3121 is provided with a limiting insertion hole matched with the limiting rod 314.

[0040] The limiting rod 314 is not completely vertically acted on the support net 312 by the magnetic attraction assembly 313. When the limiting rod 314 is transferred between the two support nets 312, the position of the limiting rod 314 on the two support nets 312 may be offset, causing the limiting rod 314 to reduce or expand the limiting range when the limiting rod 314 is limited again. Therefore, the mounting bin 3121 is arranged on the support net 312, and the limiting insertion hole is arranged in the middle of the mounting bin 3121. The magnetic attraction assembly 313 is mounted in the mounting bin 3121, avoiding the contact between the electroplating solution and the magnetic attraction assembly 313. After the automotive trim part is placed on the support net 312, the worker puts the limiting rod 314 into the corresponding limiting insertion hole. At this time, the magnetic attraction assembly 313 in the mounting bin 3121 immediately generates an attractive force on the limiting rod 314, fixing the limiting rod 314 in the limiting insertion hole, ensuring that the limiting rod 314 is stably erected and forms a limiting area around the automotive trim part. When the limiting rod 314 needs to be transferred to the upper support net 312, the magnetic attraction assembly 313 in the mounting bin 3121 of the upper support net 312 generates an attractive force on the limiting rod 314 in the limiting insertion hole of the lower support net 312. Since the limiting rod 314 is limited in the limiting insertion hole, under the action of the attractive force, the limiting rod 314 can only move along the axis direction of the limiting insertion hole, which enables the limiting rod 314 to be accurately inserted into the limiting insertion hole in the middle of the mounting bin 3121 of the upper support net 312 from the limiting insertion hole of the lower support net 312. After the electroplating of one side of the automotive trim part is completed, the transfer operation of the limiting rod 314 is performed again. Under the limitation of the limiting insertion hole, the limiting rod 314 is accurately reset, ensuring that the limiting range remains fixed each time the limiting is performed, providing stable limiting protection for the turnover of the automotive trim part and the electroplating of the other side, thereby realizing the fixed limiting range after the transfer of the limiting rod 314.

[0041] Referring to Figure 3 and Figure 5 The magnetic attraction assembly 313 includes an electromagnetic ring 3131 and a cover plate 3132. The electromagnetic ring 3131 is arranged in the mounting bin 3121 and is electrically connected between the electromagnetic rings 3131. The cover plate 3132 is arranged on the mounting bin 3121 and is used to separate the electromagnetic ring 3131 and the electroplating solution. The cover plate 3132 is provided with a through hole coaxial with the limiting insertion hole in the middle.

[0042] When the automobile interior part is placed on the lower support net 312, the staff inserts the limiting rod 314 into the limiting hole, one end of the limiting rod 314 extends out through the through hole in the middle of the cover plate 3132, at this time, the electromagnetic ring 3131 is immediately connected to the current, the electromagnetic ring 3131 generates magnetism after being electrified, and the limiting rod 314 is fixed in the limiting hole, forming a stable limiting area, when the limiting rod 314 needs to be transferred to the upper support net 312, the operator first disconnects the power supply of the electromagnetic ring 3131 on the lower support net 312, the electromagnetic ring 3131 loses magnetism, and the suction force on the limiting rod 314 is released, then the power supply of the electromagnetic ring 3131 on the upper support net 312 is connected, the electromagnetic ring 3131 generates a magnetic force to attract the limiting rod 314 upward, because the part of the limiting rod 314 that passes through the through hole of the cover plate 3132 forms a long guiding section, under the action of the suction force of the electromagnetic ring 3131, the limiting rod 314 can be guided along the axis of the limiting hole and the through hole of the cover plate 3132, and accurately transferred from the lower support net 312 to the limiting hole of the upper support net 312, when the limiting rod 314 is reset after the automobile interior part is chrome-plated on one side and before chrome-plating on the other side, the power supply of the electromagnetic ring 3131 is controlled to make the limiting rod 314 accurately reset under the guidance of the through hole of the cover plate 3132, providing stable limiting protection for the turnover of the interior part and subsequent chrome-plating operation, so that the limiting rod 314 can be flexibly fixed and transferred between the two support nets 312.

[0043] Referring to Figure 5 As shown in the figure: the magnetic attraction assembly 313 further comprises a limiting seat 3133, the limiting seat 3133 is fixed on the cover plate 3132, and the limiting seat 3133 is used to prevent the limiting rod 314 from moving.

[0044] When the electromagnetic ring 3131 exerts a suction force on the limiting rod 314, one end of the limiting rod 314 will continue to move downward under the action of gravity after passing through the through hole without being limited, so it is necessary to limit the movement distance of the limiting rod 314, when the electromagnetic ring 3131 on the lower side exerts a suction force on the limiting rod 314, the lower end of the limiting rod 314 is blocked by the limiting seat 3133, so that the limiting rod 314 stops moving downward, when the electromagnetic ring 3131 on the upper side exerts a suction force on the limiting rod 314, the limiting rod 314 moves upward and stops moving after the upper end of the limiting rod 314 contacts the limiting seat 3133, so that the limiting rod 314 can only move between the two limiting seats 3133, effectively limiting the movement distance of the limiting rod 314, avoiding the situation that the limiting rod 314 moves excessively due to the suction force of the electromagnetic ring 3131 and gravity, and ensuring that the limiting rod 314 can only move accurately between the two limiting seats 3133, thereby realizing the high controllability of the movement of the limiting rod 314.

[0045] Referring to Figure 6As shown: the separation structure 32 includes a driving plate 321, two separation assemblies 322 and a first driving assembly 323; the driving plate 321 is in sliding connection with the rotating shaft 211; the two separation assemblies 322 are respectively arranged at two ends of the driving plate 321, the separation assembly 322 includes two separation plates 3221, and the two ends of the separation plate 3221 are respectively hinged to the driving plate 321 and the mounting frame 311; the first driving assembly 323 is used for pushing the driving plate 321 to move.

[0046] The limiting rod 314 limits the placement position of the automotive trim, when the limiting rod 314 is shifted to the upper support net 312, in order to avoid the interference of the limiting rod 314 with the electroplating work of the automotive trim, it is necessary to separate the two support nets 312, and when separating the two support nets 312, it is necessary to control the moving direction of the support net 312 to prevent the limiting rod 314 from extruding the automotive trim, at this time, the first driving assembly 323 is started, and the first driving assembly 323 starts pushing the driving plate 321 to move towards the direction of the turnover frame 21, since the two ends of the separation plate 3221 are respectively hinged to the driving plate 321 and the mounting frame 311, the movement of the driving plate 321 drives the separation plate 3221 to rotate, and in turn pushes the two mounting frames 311 to move to both sides, so that the two support nets 312 gradually move away, and in the whole separation process, the two support nets 312 are always separated in a state of mutual parallelism, and the limiting rod 314 only moves along the axis direction of itself and cannot be inclined or deviated, thereby effectively avoiding the extrusion of the limiting rod 314 on the automotive trim, and ensuring the surface electroplating quality of the automotive trim.

[0047] Referring to Figure 6 and Figure 7 As shown: the first driving assembly 323 includes a sliding sleeve 3231 and a connecting plate 3232; the sliding sleeve 3231 is connected with the driving plate 321, the sliding sleeve 3231 is in sliding arrangement on the rotating shaft 211, and the sliding sleeve 3231 can synchronously rotate with the rotating shaft 211; the two ends of the connecting plate 3232 are provided with first linear drives 3233 mounted on the chrome plating box 1, and the connecting plate 3232 can exert an acting force on the sliding sleeve 3231 along the axis direction of the rotating shaft 211.

[0048] The first linear driver 3233 at both ends of the connecting plate 3232 is fixedly installed on the chromium-plated box 1, and limits the movement freedom of the connecting plate 3232, so that the connecting plate 3232 can only move along the action direction of the first linear driver 3233. When it is needed to push the driving plate 321 to move to realize the separation of the two support nets 312, the first linear driver 3233 is started to work and drive the connecting plate 3232 to move along the predetermined direction. Since the sliding sleeve 3231 is connected with the driving plate 321, the connecting plate 3232 drives the driving plate 321 to move along the axis direction of the rotating shaft 211 through the sliding sleeve 3231 in the moving process, and then the driving plate 321 pushes the two support nets 312 to stably separate through the separation assembly 322. When the turnover frame 21 drives the two support nets 312 to overturn, the rotating shaft 211 starts to rotate. At this time, the sliding sleeve 3231 can synchronously rotate with the rotating shaft 211, and the relative rotation between the sliding sleeve 3231 and the connecting plate 3232 occurs in the rotating process. This makes the driving plate 321 and the separation assembly 322 smoothly overturn synchronously with the two support nets 312 without affecting the separation operation of the support nets 312, thereby effectively solving the problem that the driving plate 321 needs to move along the rotating shaft 211 and synchronously rotate with the rotating shaft 211.

[0049] With reference to Figure 6 And Figure 8 It is shown that the separation structure 32 further includes a guide assembly 324, and the guide assembly 324 is arranged on one side of the turnover frame 21. The guide assembly 324 is used for guiding the translation of the two mounting racks 311.

[0050] Specifically, the guide assembly 324 includes a first guide rod 3241, two fixed plates 3242 and two springs 3243. The first guide rod 3241 is perpendicular to the turnover frame 21, and the middle part of the first guide rod 3241 is fixedly connected with the turnover frame 21. The two fixed plates 3242 are respectively fixedly connected with the two mounting racks 311, and the two fixed plates 3242 are both in sliding connection with the first guide rod 3241. The two springs 3243 are respectively sleeved on both ends of the first guide rod 3241, and the two ends of the spring 3243 are respectively in abutment with the middle part of the first guide rod 3241 and the fixed plate 3242.

[0051] When the separating assembly 322 drives the two support nets 312 to move away from each other, the movement of the support nets 312 needs to be guided to keep the support nets 312 in translation, therefore, the guide assembly 324 is arranged, when the separating assembly 322 is started to drive the two support nets 312 to move towards the turnover frame 21, the mounting frame 311 drives the fixed plate 3242 connected thereto to slide along the first guide rod 3241, in the process, the spring 3243 is compressed by the fixed plate 3242 and the elastic potential energy is continuously increased, since the first guide rod 3241 limits and guides the movement direction of the fixed plate 3242, the fixed plate 3242 can only translate along the direction of the first guide rod 3241, thereby ensuring that the support net 312 connected thereto also moves stably in a horizontal state, when it is needed to make the support net 312 move away from the turnover frame 21, the compressed spring 3243 starts to release the stored elastic potential energy to push the fixed plate 3242 to move reversely along the first guide rod 3241, and assist the support net 312 to move away from the turnover frame 21 smoothly, similarly, the first guide rod 3241 continuously plays a guiding and limiting role to ensure that the movement track of the fixed plate 3242 is stable, thereby driving the support net 312 to keep moving in a horizontal state all the time, avoiding the inclination, deviation and other situations, and guaranteeing the stability and accuracy of the movement of the support net 312.

[0052] With reference to Figure 9 As shown: the support net 312 includes two net surfaces 3122, the two net surfaces 3122 are symmetrically arranged about the middle surface of the mounting frame 311, and the opposite sides of the two net surfaces 3122 are hinged with the mounting frame 311, the two ends of the net surface 3122 are provided with opening and closing control structures 33, and the opening and closing control structures 33 are used for controlling the two net surfaces 3122 to rotate about the hinged parts with the mounting frame 311 respectively.

[0053] Since two support nets 312 are arranged on the upper and lower sides of the turnover frame 21 respectively, when the automotive interior part is placed on the support net 312 on the lower side, the support net 312 on the upper side will affect the placement of the automotive interior part by the worker, therefore, the support net 312 is arranged as two net surfaces 3122 symmetrically arranged about the middle surface of the turnover frame 21 and an opening and closing control structure 33 for controlling the two net surfaces 3122, when the automotive interior part is placed, the opening and closing control structure 33 drives the two net surfaces 3122 to rotate around the respective hinged places with the mounting frame 311, in the rotating process, the two net surfaces 3122 gradually change from the horizontal state to the vertical state, and the originally closed mounting frame 311 is opened, at this time, the net surface 3122 on the upper side no longer blocks the operation space, which is convenient for the worker to place the automotive interior part on the support net 312 on the lower side, after the automotive interior part is placed, the two net surfaces 3122 are reversely rotated again by the opening and closing control structure 33, and are restored to the horizontal state, and the mounting frame 311 is re-closed, which prepares for the subsequent chrome plating operation, through the design of the double net surfaces 3122 and the opening and closing control structure 33, the space obstruction problem in the placement process of the automotive interior part is effectively solved.

[0054] Referring to Figure 9 and Figure 10 It is shown that the opening and closing control structure 33 includes a vertical plate 331 and two second driving assemblies 332; the middle part of the vertical plate 331 is fixedly connected with the rotating shaft 211; the two second driving assemblies 332 are arranged at the two ends of the vertical plate 331 respectively, and the second driving assembly 332 is used for driving the two net surfaces 3122 of the support net 312 to rotate around the respective shaft joints with the mounting frame 311.

[0055] Specifically, the second driving assembly 332 includes two transmission rods 3321, an opening and closing plate 3322, a second guide rod 3323, a sliding block 3324 and a second linear driver 3325, the two transmission rods 3321 are connected with the two net surfaces 3122 respectively, the opening and closing plate 3322 is provided with two sliding grooves, the two transmission rods 3321 are movably connected with the two sliding grooves respectively, the second guide rod 3323 is arranged on the vertical plate 331, and the second guide rod 3323 is perpendicular to the rotating shaft 211, the sliding block 3324 is slidably arranged on the second guide rod 3323, and the sliding block 3324 is connected with the opening and closing plate 3322, and the second linear driver 3325 is used for driving the sliding block 3324 to move along the second guide rod 3323.

[0056] When it is needed to open the support net 312 located at the upper side in order to place the automotive interior part, the second linear actuator 3325 is started, the second linear actuator 3325 starts to work, drives the sliding block 3324 to slide along the second guide rod 3323, since the sliding block 3324 is connected with the opening and closing plate 3322, the movement of the sliding block 3324 drives the opening and closing plate 3322 to translate towards the direction away from the turnover frame 21, along with the movement of the opening and closing plate 3322, the two transmission rods 3321 which are slidably connected with the opening and closing plate 3322 in the sliding groove slide away from each other in the sliding groove, since the transmission rod 3321 is connected with the net surface 3122, the two transmission rods 3321 respectively drive the corresponding net surface 3122 to rotate around the shaft joint with the mounting frame 311, so that the two net surfaces 3122 which are originally in the horizontal state are gradually rotated to the vertical state, the mounting frame 311 is opened, sufficient space is left for the worker to place the automotive interior part, when the automotive interior part is placed, the second linear actuator 3325 is started in the reverse direction, the sliding block 3324, the opening and closing plate 3322 are moved in the reverse direction, the transmission rod 3321 and the net surface 3122 are rotated in the reverse direction, the two net surfaces 3122 return to the horizontal state, the mounting frame 311 is re-closed, so that the synchronous adjustment of the state of the two net surfaces 3122 is realized.
