Description

Technical Field

[0001] This utility model relates to the field of electroplating technology for plastic products, and in particular to an electroplating device for plastic products. Background Technology

[0002] Electroplating of plastic products is a process that deposits a metal layer on the surface of plastic using chemical and electrochemical methods. It is widely used in the automotive, electronics, and home appliance industries to improve the decorative properties, conductivity, and corrosion resistance of products. Electroplating equipment typically includes multiple treatment tanks, such as degreasing, activation, electroplating, and cleaning tanks. Plastic workpieces must pass through each tank sequentially to complete different processes. However, because plastic itself is non-conductive, special pretreatment, such as chemical plating, is required before electroplating. Furthermore, the compositions of the solutions in each tank vary significantly; cross-contamination can lead to reduced coating adhesion, surface defects, and other problems, severely impacting product quality.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] This utility model embodiment provides a plastic product electroplating device 100. To better illustrate the technical solution of this utility model, the first direction V1 is defined to be perpendicular to the second direction V2, and the second direction V2 is a vertical direction.

[0018] Please refer to Figures 1 to 4The aforementioned electroplating apparatus 100 for plastic products includes: Multiple processing tanks 110 and multiple draining tanks 120; each of the processing tanks 110 and the draining tanks 120 are spaced apart along a first direction V1; Base 130; the treatment tank 110 and the drain tank 120 are fixedly disposed on the base 130; A gantry frame 140 includes a support 141, a motor assembly 142, and a first crossbeam 143. The support 141 is movable relative to the base 130 along a first direction V1. The motor assembly 142 is fixed to the support 141 and is used to drive the first crossbeam 143 to move along a second direction V2. Hanging fixture assembly 150; the hanging fixture assembly 150 includes a second crossbeam 151 and a hanging fixture 152; the second crossbeam 151 has a first guide post 151a and a first elastic element 151b, the first elastic element 151b is disposed on the outer periphery of the first guide post 151a, the first guide post 151a is slidably engaged with the first crossbeam 143; the first guide post 151a has a first limiting part, the first limiting part is limitedly engaged with the first crossbeam 143; the hanging fixture 152 is fixedly connected to the second crossbeam 151.

[0019] Specifically, the treatment tank 110 may include an electroplating tank, a degreasing tank, an activation tank, a cleaning tank, etc., for completing different surface treatment processes of plastic products; the material of the treatment tank 110 may be corrosion-resistant PVC, PP, or stainless steel. The draining tank 120 is used to drain residual liquid from the surface of the workpiece; the bottom of the draining tank 120 may be provided with an inclined guide surface, a collection tank, or a liquid collection pipe to facilitate centralized recycling or treatment of waste liquid.

[0020] Furthermore, the base 130 may be a welded steel frame or an aluminum alloy frame, with a guide rail or roller groove on its top to support the processing tank 110 and the drain tank 120, and to guide the movement of the gantry 140.

[0021] Specifically, the support 141 can be connected to the base 130 via a linear guide, gear rack, or synchronous belt to achieve movement in the first direction V1. The motor assembly 142 includes a drive motor and a transmission mechanism, which drives the first crossbeam 143 to move in the second direction V2. Optionally, the transmission mechanism is a lead screw. The first crossbeam 143 cooperates with the lead screw, and both ends of the first crossbeam 143 are slidably connected to the support 141.

[0022] Specifically, the second crossbeam 151 of the hanging assembly 150 is arranged parallel to the first crossbeam 143 and is slidably connected by a first guide post 151a. The end of the first guide post 151a is provided with a first limiting part to prevent it from detaching from the first crossbeam 143. The first limiting part can be a snap ring, a pin, or a nut. The first elastic element 151b is a helical spring and is sleeved on the outer periphery of the first guide post 151a. The hanging device 152 is fixed to the second crossbeam 151. The hanging device 152 can be a hook-type hanging device 152 or a frame-type hanging device 152; the specific form of the hanging device 152 is not limited here.

[0023] It is understood that the technical solution of this embodiment, through the structural design of the treatment tank 110 and the drain tank 120 being spaced apart, combined with the first guide post 151a and the first elastic element 151b of the hanger assembly 150, effectively solves the technical problem of unstable electroplating quality caused by cross-contamination of the tank solutions in the prior art. Specifically, when the gantry 140 drives the hanger assembly 150 to transfer the workpiece from one treatment tank 110 to the drain tank 120, under the sudden stop of the motor assembly 142, the rebound force of the first elastic element 151b causes the second crossbeam 151 and the hanger 152 to vibrate up and down due to inertia, forcibly draining the residual liquid from the surface of the workpiece. Therefore, the technical solution of this utility model not only avoids the problem of liquid dripping and contaminating the liquid in the subsequent treatment tank 110 in traditional devices, but also achieves an efficient and continuous operation process through the coordinated movement of the base 130 and the gantry 140, thereby significantly improving the electroplating quality and the stability of the electroplating process.

[0024] Please refer to Figure 2 In one specific embodiment, the hanging assembly 150 further includes an adjusting beam 153, which is disposed between the first beam 143 and the second beam 151. The adjusting beam 153 is in a limiting cooperation with the first guide post 151a and is used to adjust the contraction range of the first elastic member 151b.

[0025] Specifically, the adjusting crossbeam 153 is located between the first crossbeam 143 and the second crossbeam 151. The three are connected in series through the first guide post 151a to form an adjustable elastic buffer system to adapt to the use of workpieces of different specifications.

[0026] Optionally, the adjusting beam 153 and the first guide post 151a are limited by a limiting pin; or fixed by a threaded locking sleeve.

[0027] In one embodiment, a buffer assembly 160 is further included, the buffer assembly 160 including a base plate 161, a spring 162 and a base 163; the bottom of the hanger is fixedly connected to the base plate, and a second guide post 161a is formed on the side of the base plate 161 opposite to the hanger. The second guide post 161a slides with the base 163 in a second direction V2 and is limited to the base 163; the spring 162 is disposed on the outer periphery of the second guide post 161a and is located between the base plate 161 and the base 163.

[0028] Understandably, by setting up a secondary buffer mechanism consisting of base plate 161, spring 162, and base 163, the process defects caused by mechanical vibration during electroplating are solved: when the workpiece is immersed in the treatment tank 110 or the drain tank 120 and shakes, the elastic deformation of spring 162 effectively absorbs the instantaneous impact energy, improving the connection stability between the workpiece and the hanger 152.

[0029] Please continue reading. Figure 2 , Figure 3 and Figure 4 In one specific embodiment, the base 163 is further provided with a clearance portion 163a, which is used to accommodate the second guide post 161a and prevent the second guide post 161a from protruding from the base 163.

[0030] Specifically, the avoidance part 163a not only prevents the guide post from colliding with the bottom of the groove when it shakes violently, but also allows the lower surface of the base 163 to directly and smoothly contact the ground when it is stationary.

[0031] In one embodiment, the depth of the drain trough 120 is less than the depth of the treatment trough 110.

[0032] It is understandable that a shallower drainage groove 120 results in higher drainage efficiency for the workpiece. This also reduces the lifting load on the gantry 140.

[0033] In summary, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
