Description

Technical Field

[0001] The present invention relates to the technical field of electroplated part appearance detection, and in particular to an electroplated part appearance detection system. Background Art

[0002] Electroplating is a process that uses electrolysis to attach a layer of metal film to the surface of a metal or other material part. During the production process of electroplated parts, it is necessary to inspect their appearance. Chinese patent application CN113834815A discloses an appearance inspection device for irregular automotive electroplated parts and a method of using the device, including a visual system, a sorting system, a conveying system and a machine. The visual system, the sorting system and the conveying system are all installed on the machine. This patent application uses a robotic arm to drive the workpiece to move, and then uses an industrial camera to perform appearance inspection. However, when small electroplated parts are produced, the efficiency of using a robotic arm to inspect the electroplated parts one by one is low, and the cost of a high-precision robotic arm is high, which will increase the cost of production; Chinese patent CN116500049B discloses a A kind of electroplated parts appearance inspection equipment and its inspection system, including a built-in light-emitting panel, a shielding plate and an appearance inspection structure. This patent flips the electroplated parts through a flipping mechanism, and inspects the two ends of the electroplated parts through two inspection mechanisms. This method is more efficient when inspecting larger electroplated parts, and has lower production costs than the method of flipping and inspecting them with a robot arm. However, it is still unable to inspect smaller electroplated parts. When multiple small electroplated parts are laid on a conveyor belt and transported to the flipping mechanism, the flipping mechanism of this patent cannot accurately flip the parts, so that the inspection mechanism will cause repeated inspections when inspecting multiple small parts, resulting in low efficiency. At the same time, its equipment occupies a high space, which will also increase production costs. Summary of the invention

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 5 and Fig.12 As shown: A system for inspecting the appearance of electroplated parts, comprising a conveyor belt 1, on which a plurality of receiving components 2 arranged along its transmission direction are arranged, and on which a plurality of clamping positions 21 arranged in a rectangular row are arranged, and the clamping positions 21 are used to clamp the electroplated parts falling into the clamping positions 21; a vibrating material tray 3 is arranged above the conveyor belt 1, and on which mounting holes 31 having the same number as and one-to-one corresponding to the clamping positions 21 are arranged, and the material tray 3 is used to put the electroplated parts onto the clamping positions 21 of the receiving component 2; a first inspection mechanism 11 and a second inspection mechanism 12 for inspecting the appearance of workpieces on the receiving component 2 are arranged on the side of the conveyor belt 1; a flipping component 13 for driving the receiving component 2 on the conveyor belt 1 to flip as a whole is arranged between the first inspection mechanism 11 and the second inspection mechanism 12.

[0033] First, the electroplated parts are placed on the material tray 3, and the vibration of the material tray 3 drives the electroplated parts to move, so that the electroplated parts are moved out of the mounting holes 31, thereby allowing the electroplated parts to fall on the corresponding clamping positions 21 on the receiving component 2. The clamping positions 21 are preferably clamping claws, and the clamping claws can be electrically driven or elastically driven. The electroplated parts are clamped by the clamping claws to fix the electroplated parts, and the movement of the receiving component 2 is driven by the conveyor belt 1. The movement of the receiving component 2 drives the electroplated parts in the clamping positions 21 to move, so that the receiving component 2 first moves to the bottom of the first detection mechanism 11, and the first detection mechanism 11 performs an appearance inspection on the electroplated parts on the receiving component 2. After the inspection is completed, the receiving component 2 is driven by the conveyor belt 1 to move to the flipping component 13, and the flipping component 13 drives the receiving component 2 and the electroplated parts on the receiving component 2 The parts are flipped over as a whole, and then the receiving component 2 is driven by the conveyor belt 1 to move to the second detection mechanism 12, and the reverse side of the electroplated parts on the receiving component 2 is detected by the second detection mechanism 12. It should be noted that in the initial state, the receiving component 2 can only clamp the bottom of the electroplated parts. After the receiving component 2 is flipped over, since the receiving component 2 is still clamped at the bottom of the electroplated parts, there is a gap between the receiving component 2 and the conveyor belt 1. By loosening the clamping of the electroplated parts, the receiving component 2 falls on the conveyor belt 1 under the action of gravity, and by clamping the electroplated parts again, the electroplated parts on the receiving component 2 at this time can be clamped to the top of the original electroplated parts. In this way, the dead angle caused by the clamping position 21 when clamping the electroplated parts can be avoided, and at the same time, the second detection mechanism 12 can perform a comprehensive appearance inspection on the electroplated parts.

[0034] By setting a vibrating tray 3, automatic loading is realized. The mounting hole 31 on the vibrating tray 3 can accurately place the electroplated parts on the clamping position 21, thereby realizing accurate loading operation. The setting of the flip assembly 13 enables the material receiving assembly 2 to realize overall flipping, ensuring complete detection of both sides of the electroplated parts, effectively reducing the detection blind area, improving the detection accuracy, and solving the problem of inaccurate flipping of small and medium-sized workpieces in the prior art; through the setting of the clamping position 21, workpieces with complex geometric shapes and small sizes can be firmly clamped and detected. The clamping position 21 can be adjusted as needed to adapt to workpieces of different sizes, enhancing the flexibility of the equipment and meeting the requirements of different product specifications. Since the entire detection process is highly automated, the dependence on manual operation is reduced, thereby reducing labor costs. The automated design reduces downtime and adjustment time in the production process, and improves the continuity and stability of the production line; since the material receiving rack is set on the conveyor belt 1, the placement of the equipment can be more compact, reducing the space requirements for production.

[0035] like Figures 1 to 6As shown: the material receiving assembly 2 includes a first material rack 22 and a second material rack 24. The second material rack 24 can be slidably arranged on the first material rack 22. The first material rack 22 and the second material rack 24 are both provided with a plurality of mounting strips 25 equidistantly arranged along the transmission direction of the conveyor belt 1. The mounting strips 25 are wavy structures, and the mounting strips 25 of the first material rack 22 and the second material rack 24 are arranged in a mirror-symmetrical state.

[0036] Through the mirror-symmetrical mounting bars 25 on the first material rack 22 and the second material rack 24, since the mounting bars 25 are of a wavy structure, after the mounting bars 25 on the first material rack 22 and the second material rack 24 are close to each other, a plurality of holes are formed between the mounting bars 25 according to the waves, and by further moving the second material rack 24, the size of the hole can be changed, and the electroplated parts falling into the hole can be clamped by the change in the area of ​​the hole, thereby reducing the problem of providing clamping claws at each clamping position 21, reducing the cost of equipment, and quickly achieving synchronous clamping of multiple electroplated parts, thereby improving the synchronization and integrity of the equipment, and accurately clamping electroplated parts of different sizes. This design effectively ensures the stability of the position of each electroplated part during the detection process.

[0037] like Figures 1 to 6 As shown: a slide groove 23 extending along the transmission direction of the conveyor belt 1 is arranged on the side wall of the first material rack 22, and a mounting rod 241 passing through the slide groove 23 and capable of sliding on the slide groove 23 is arranged on the second material rack 24, and a first elastic member 242 is arranged on the mounting rod 241 and the side wall of the first material rack 22, and the first elastic member 242 is used to drive the mounting strip 25 on the first material rack 22 to approach the corresponding mounting strip 25 on the second material rack 24.

[0038] The support of the first elastic member 242 can drive the mounting rod 241 to slide along the slide groove 23 through the elastic force, so that in the initial state, the mounting strip 25 on the first material rack 22 is close to the corresponding mounting strip 25 on the second material rack 24, thereby making the clamping position 21 in the initial state in a clamping state, and when the material tray 3 is discharging materials for the receiving component 2, the mounting rod 241 is pushed to move in the opposite direction, so that the mounting strip 25 on the first material rack 22 and the mounting strip 25 on the second material rack 24 are separated from each other, so that the electroplated parts in the mounting holes 31 of the material tray 3 can accurately fall between the mounting strips 25 of the first material rack 22 and the second material rack 24, and the first elastic member 242 is reset to clamp the electroplated parts between the two, so that the subsequent receiving component 2 can drive multiple electroplated parts to be transported by the conveyor belt 1; through the above method, the receiving component 2 can remain stable during the transportation of the electroplated parts, so that the electroplated parts are always clamped by the mounting strips 25 on the first material rack 22 and the second material rack 24, thereby improving the stability of the equipment.

[0039] like Figures 1 to 6As shown: a mounting frame 14 is arranged on the side of the conveyor belt 1, and a sliding rod 141 parallel to the mounting rod 241 is arranged on the mounting frame 14, the sliding rod 141 can be slidably arranged on the mounting frame 14, and a wedge block 142 is arranged on one end of the mounting rod 241 close to the sliding rod 141.

[0040] After the receiving assembly 2 moves to the side of the mounting rack 14, the sliding rod 141 is pushed to move the sliding rod 141 closer to the mounting rod 241. A section of the wedge block 142 close to the sliding rod 141 is provided with an inclined surface, and the first driving block contacts the wedge block 142, so that the sliding rod 141 can drive the wedge block 142 to move, so that the wedge block 142 drives the mounting rod 241 to slide along the slide groove 23, so that the mounting strips 25 of the first material rack 22 and the second material rack 24 are separated from each other. In order to better contact the sliding rod 141 with the wedge block 142, a pulley is provided at the end of the sliding rod 141 to reduce The friction between the two facilitates better sliding of the wedge block 142. The sliding rod 141 is driven by an electromagnet. An electromagnet can be set on the end of the sliding rod 141 away from the mounting rod 241, and a magnetic block is set on the mounting frame 14. A second elastic member is set between the end of the sliding rod 141 and the mounting frame 14. By energizing the electromagnet, the electromagnet can generate magnetic force to approach the magnetic block, thereby driving the sliding rod 141 to move toward the mounting frame 14, so that the sliding rod 141 can drive the mounting rod 241. After the power to the electromagnet is disconnected, the sliding rod 141 will be reset under the elastic force of the second elastic member.

[0041] There are two sliding rods 141, one is located beside the material tray 3, by controlling the mounting bars 25 on the first material rack 22 and the second material rack 24 to move away from each other, it is convenient to receive the materials dropped from the material tray 3, and the second is located beside the second detection component, by controlling the mounting bars 25 on the first material rack 22 and the second material rack 24 to move away from each other, the receiving component 2 located at the bottom of the original electroplated part after flipping can slide to its top under the action of gravity, thereby facilitating the second detection mechanism 12 to perform a comprehensive inspection of the electroplated part, avoiding blind spots during inspection and improving the accuracy of inspection.

[0042] It should be noted that the first material rack 22 is made of a material with a certain mass, and the second material rack 24 is made of a lighter material. As a result, when the sliding rod 141 drives the wedge block 142, the sliding rod 141 can only drive the mounting rod 241 through the wedge block 142, and drive the second material rack 24 to move through the mounting rod 241. The first material rack 22 will not be moved due to the force applied by the sliding rod 141.

[0043] like Figures 1 to 3 , Figures 6 to 11As shown: the flip assembly 13 includes a support frame 131, two abutment rods 1311 and two support rods 1312. The support frame 131 is located below the conveyor belt 1. The two abutment rods 1311 are fixedly connected to the two ends of the support frame 131 respectively, and the two abutment rods 1311 are coaxial and extend along the width direction of the conveyor belt 1. The two support rods 1312 are rotatably arranged on the side of the abutment rod 1311. A section of the support rod 1312 away from the support frame 131 is provided with a cross bar 13121 parallel to the abutment rod 1311. Both ends of the first material frame 22 are provided with U-shaped connectors 221 matching the abutment rods 1311, and two guide rods 222 are provided on both sides of the first material frame 22.

[0044] When the first material rack 22 is placed on the conveyor belt 1, the two guide rods 222 on both sides of the first material rack 22 are located on the outside of the conveyor belt 1. Through the above method, when the support rod 1312 drives the cross bar 13121, the contact between the cross bar 13121 and the guide rod 222 can drive the first material rack 22 to flip, and at the same time, the first material rack 22 can be placed on the conveyor belt 1 more stably, so that the conveyor belt 1 will not shake when transporting the first material rack 22. When the conveyor belt 1 transports the first material rack 22, the U-shaped connection on the end of the first material rack 22 The head 221 will first contact the abutment rod 1311 on the support frame 131, so that the connecting head 221 is stuck on the abutment rod 1311. At this time, the first material rack 22 stops moving, and the cross bar 13121 is driven to approach the first material rack 22 through the rotation of the support rod 1312, until the cross bar 13121 contacts the guide rod 222 of the first material rack 22. At this time, the cross bar 13121 will drive the first material rack 22 to rotate around the abutment rod 1311 until the entire first material rack 22 flips over, thereby causing the clamped electroplated parts on the first material rack 22 to flip over.

[0045] like Figures 1 to 4 , Figures 6 to 11 As shown: the two guide rods 222 are both inclined, and the two guide rods 222 are centrally symmetrically arranged with respect to the center of the side of the first material rack 22; a mounting groove 223 extending in the vertical direction is arranged at the angle between the guide rod 222 and the first material rack 22; a slider 13122 which can slide along its length direction is arranged on the support rod 1312; the slider 13122 is elastically connected to the support rod 1312; a cross bar 13121 is arranged on the slider 13122 so as to slide along its axial direction; and the cross bar 13121 is elastically connected to the slider 13122.

[0046] After the flip assembly 13 drives the first material rack 22 to flip, the first material rack 22 falls on the conveyor belt 1 in a free fall state, which will cause the first material rack 22 to fall unstably and affect the multiple electroplated parts on the first material rack 22. The guide rod 222 is arranged obliquely so that the cross bar 13121 can be stuck at the angle between the guide rod 222 and the first material rack 22 when driving the first material rack 22, so that the first material rack 22 after flipping will not directly fall on the conveyor belt 1 in a free fall state, so that the first material rack 22 The rack 22 can be hung on the cross bar 13121 through the guide rod 222 and placed stably on the conveyor belt 1. After the first rack 22 contacts the conveyor belt 1, the cross bar 13121 will slide along its axial direction so that the cross bar 13121 can slide along the mounting groove 223, thereby making the cross bar 13121 away from the first rack 22 so that it can continue to rotate with the support rod 1312. The two guide rods 222 are centrally symmetrical and the connectors 221 at both ends of the first rack 22 are set so that the flip The first rack 22 does not need to be flipped when the conveyor belt 1 transports it to the flip assembly 13 again, so that the first rack 22 can continue to be flipped by the flip assembly 13, reducing labor or increasing the adjustment of the first rack 22 by the flip assembly 13, which can lower the production cost and enable the equipment to operate continuously. In order to better operate the flip assembly 13, an extension rod 2221 extending in the vertical direction can be set on the guide rod 222, and the extension rod 2221 and the cross bar 1312 can be used to rotate the first rack 222. 1, the cross bar 13121 slides along the length direction of the support rod 1312 through the slider 13122, so that the cross bar 13121 can slide along the support rod 1312 through the slider 13122, so that the cross bar 13121 can slide along the guide rod 222 and the extension rod 2221, so that the cross bar 13121 can better contact with the guide rod 222, so that it can be accurately guided to the angle between the guide rod 222 and the first material rack 22, thereby driving the first material rack 22 to achieve a smooth flip.

[0047] like Figure 3 , Figures 7 to 11 As shown: driving rods 13123 are provided at both ends of the top of the support frame 131, and two support rods 1312 are respectively sleeved on the two driving rods 13123, and a rotating shaft 1314 and a rotating driving motor 1313 are provided in the middle of the support frame 131, and the driving rod 13123 and the rotating shaft 1314 are connected by a synchronous belt 1315.

[0048] The support rod 1312 is driven to rotate by the driving rod 13123, and the driving rod 13123 is close to the conveyor belt 1, so that the driving motor cannot be installed on the same axis as the driving rod 13123. The two driving rods 13123 can be synchronously connected with the rotating shaft 1314 through the synchronous belt 1315, so as to synchronously drive the two support rods 1312 to rotate, thereby driving the first material rack 22 to flip. The rotating driving motor 1313 is set in the center of the rotating shaft 1314. The rotating driving motor 1313 is a servo motor with a dual output shaft, and the rotating shaft 1314 is transmission-connected to it.

[0049] like Figure 1 and Fig.12 As shown: a vibration plate 32 is arranged beside the conveyor belt 1, and the material tray 3 is rotatably arranged on the vibration plate 32, and a linear drive component 33 for driving the material tray 3 to rotate is arranged below the conveyor belt 1.

[0050] The vibration of the vibrating plate 32 drives the electroplated parts into the mounting holes 31 on the material tray 3, and the electroplated parts are placed on the clamping position 21 of the first material rack 22 that matches it through the mounting holes 31. After the placement is completed, the material tray 3 is driven to rotate by the linear drive component 33, so that the material tray 3 is away from the first material rack 22, thereby facilitating the movement of the first material rack 22. At the same time, the rotating material tray 3 can make the electroplated parts be placed intermittently. When the material tray 3 rotates to the top of the first material rack 22, the electroplated parts are blocked. After moving to be parallel to the first material rack 22, the electroplated parts are transferred to the mounting hole 31 of the material tray 3 again. Two slidable connecting rods 331 are provided on the side of the first material tray 3 close to the vibration plate 32. The linear drive assembly 33 includes a driving frame 332 mounted on the two connecting rods 331 and a cylinder 333 for driving the driving frame 332 to move in a vertical direction. The driving frame 332 is driven to move by the cylinder 333, and the connecting rod 331 is pulled by the driving frame 332, so that the connecting rod 331 can drive the material tray 3 to rotate.

[0051] like Figures 1 to 3 As shown, the first detection mechanism 11 and the second detection mechanism 12 both include a fixing frame 111 , an illumination lamp 112 and a detection camera 113 arranged on the fixing frame 111 .

[0052] By setting the fixing frame 111 beside the conveyor belt 1, the lighting lamp 112 and the detection camera 113 can be set above the conveyor belt 1. The lighting lamp 112 is used to perform light compensation for the electroplated parts so that the electroplated parts can be better detected. The detection camera 113 takes pictures of the electroplated parts and the rear-end controller recognizes the taken pictures to determine whether the appearance of the electroplated parts is qualified.

[0053] like Figure 1 , Figure 2 and Figure 6 As shown: a sensor 15 for monitoring the position of the butt-jointed material assembly 2 is arranged beside the conveyor belt 1 .

[0054] The position of the receiving component 2 is identified by the sensor 15, and the identified signal is sent to the rear-end controller, so that the conveyor belt 1 can effectively control the movement of the receiving component 2 through the identification signal obtained by the rear-end controller, thereby improving the degree of automation of the equipment.

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
