Description

Technical Field

[0001] This utility model application relates to the technical field of detection devices after gate removal, specifically a device for detecting defects in gate removal of refrigerator door trim strips. Background Technology

[0002] The lower door trim strip is an important component of the refrigerator's appearance, and its molding process typically uses injection molding. During injection molding, excess injection residue, known as gate waste, is formed at the gate area of ​​the mold. To ensure the trim strip's appearance quality and dimensional accuracy, the gate needs to be removed after injection molding. For example, mechanical cutting may result in uneven cuts and burr residue; these defects not only affect the trim strip's aesthetics but may also reduce its structural strength and sealing performance, thus impacting the overall quality of the refrigerator.

[0003] Currently, the common method for gate removal in the industry is to use a gate removal machine. The specific process is as follows: the trim strip is placed on the machine with the gate facing downwards. The machine rises to the gate location using pneumatic shears and cuts the gate using the shearing force of the pneumatic shears. This method can quickly and effectively remove gate waste to a certain extent. However, in actual production, due to various factors, the trim strip may have various defects after removal. After gate removal, the trim strip is usually transferred to an inspection device for defect detection using a robotic arm. However, because the gate removal area of ​​the trim strip faces downwards, and the inspection camera generally takes pictures from above, this limited perspective means that the gate removal area cannot be directly captured by the camera. This results in many defects located at the gate removal area, such as uneven cuts, residual burrs, and melt marks, not being detected by the inspection system, leading to a large number of missed defects and seriously affecting product quality. Utility Model Content

[0004] The purpose of this utility model application is to provide a device for detecting defects in the gate cutting of the lower trim strip of a refrigerator door. By setting a flipping component, the trim strip is flipped so that the gate cutting part on the trim strip faces upward, which is convenient for the detection camera to detect.

[0005] To address the problems in the prior art, this utility model application provides a device for detecting defects in the gate cutting of a refrigerator door trim strip, comprising: a frame; a visual inspection device disposed on one side of the top of the frame; and a trim strip clamping device disposed on the side of the top of the frame away from the visual inspection device. The trim strip clamping device includes a flipping assembly capable of being flipped, the flipping assembly including a base fixed to the top of the frame, the flipping assembly also including a support platform, and a connecting block disposed at the bottom of the support platform. A connecting shaft is connected to the connecting block, and the connecting shaft is rotatably connected to the base. When the support platform is flipped, the trim strip can be flipped to the bottom of the visual inspection device.

[0006] Preferably, the trim clamping device further includes two first clamping mechanisms disposed on the support platform and capable of clamping the two ends of the trim for fixing the trim.

[0007] Preferably, the trim clamping device further includes several second clamping mechanisms disposed on the support platform and capable of clamping the two sides of the trim for fixing the trim.

[0008] Preferably, the first clamping mechanism includes a first telescopic drive member disposed at the bottom of the support platform, and the output end of the first telescopic drive member is connected to a first clamping plate, and the first clamping plate can abut against the end face of the trim strip.

[0009] Preferably, the second clamping mechanism includes a plurality of second telescopic drive members installed at the bottom of the support platform, the output end of the second telescopic drive members is connected to a second clamping block, and the second clamping block abuts against the side of the trim strip.

[0010] Preferably, the trim clamping device further includes a drive assembly disposed on the side of the base and used to support the platform to flip the trim to the bottom of the visual inspection device.

[0011] Preferably, the drive assembly includes a worm gear fixed on the connecting shaft, and the drive assembly also includes a rotary drive component fixed on the base, and the output end of the rotary drive component is connected to a worm, which meshes with the worm gear.

[0012] Preferably, the visual inspection device includes a connecting column vertically arranged on the top of the frame, a support member that can move up and down is slidably arranged on the connecting column, and a fixing bolt that can fix the support member to the connecting column is also provided on the support member. A detection camera is also arranged at the end of the support member away from the connecting column, and a fixing bolt that can fix the detection camera to the support member is also provided on the support member.

[0013] The advantages of this utility model application compared to the prior art are: This application includes a flipping assembly, which mainly consists of a base and a support platform. The support platform is capable of rotating on the flipping assembly. In actual operation, the trim strip to be inspected is placed on the support platform. When the support platform flips, the gate-cut section of the trim strip is rotated upwards, providing an ideal viewing angle for the subsequent inspection by the inspection camera. This ensures that the inspection camera can clearly and comprehensively capture various defect information at the gate-cut section. To ensure the consistency of the trim strip's position on the support platform, this application also includes a first clamping mechanism and a second clamping mechanism. Through the coordinated action of these two clamping mechanisms, the trim strip can be positioned at the center of the support platform, ensuring that the position of each trim strip remains the same during the inspection process, effectively avoiding inspection errors caused by trim strip position deviations. Furthermore, in the transmission method of the flipping assembly, this application adopts a transmission structure using a worm gear and worm wheel combination. The worm gear and worm wheel transmission has a self-locking characteristic, which allows the support platform to remain stable after being flipped to the designated position and will not rotate unexpectedly due to external factors (such as vibration, collision, etc.). This further ensures the stability of the trim position during the inspection process and provides a strong guarantee for defect detection of gate cutting. Attached Figure Description

Detailed Implementation

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-6 As shown, this utility model application provides a refrigerator door trim gate cutting defect detection device, including: a frame 1, a visual inspection device 2, which is set on one side of the top of the frame 1; a trim clamping device 3, which is set on the top of the frame 1 away from the visual inspection device 2; the trim clamping device 3 includes a flipping component 31 that can be flipped, the flipping component 31 includes a base 311 fixed to the top of the frame 1, the flipping component 31 also includes a support platform 312, the bottom of the support platform 312 is also provided with a connecting block 3121, the connecting block 3121 is connected to a connecting shaft 3122, and the connecting shaft 3122 is rotatably connected to the base 311, so that when the support platform 312 is flipped, the trim can be flipped to the bottom of the visual inspection device 2.

[0023] When it is necessary to inspect the gate cutting defect of the lower trim strip of the refrigerator door, the trim strip is first placed on the support platform 312 of the trim strip clamping device 3. The trim strip clamping device 3 clamps and fixes the trim strip to ensure its stable position. Since the gate cutting position is at the bottom, in order to ensure comprehensive inspection, the flipping component 31 of the trim strip clamping device 3 starts to work. The support platform 312 flips over through the rotatable connection between the connecting shaft 3122 and the base 311, flipping the trim strip to the bottom of the visual inspection device 2, which facilitates the visual inspection device 2 to perform gate cutting defect inspection.

[0024] The trim clamping device 3 also includes two first clamping mechanisms 33 disposed on the support platform 312 and capable of clamping the two ends of the trim for fixing the trim. The first clamping mechanism 33 includes a first telescopic drive member 331 disposed at the bottom of the support platform 312, and the output end of the first telescopic drive member 331 is connected to a first clamping plate 332, and the first clamping plate 332 can abut against the end face of the trim.

[0025] When it is necessary to inspect the gate cutting defect of the lower trim strip of the refrigerator door, place the trim strip on the support platform 312 of the trim strip clamping device 3. Then, activate the two first clamping mechanisms 33, and the first telescopic drive member 331 starts to work, with its output end extending out to push the first clamping plate 332 to move towards both ends of the trim strip until the first clamping plate 332 is in close contact with the end face of the trim strip, thus firmly fixing the trim strip on the support platform 312.

[0026] The trim clamping device 3 also includes several second clamping mechanisms 34 disposed on the support platform 312 and capable of clamping the two sides of the trim for fixing the trim. The second clamping mechanism 34 includes several second telescopic drive members 341 installed at the bottom of the support platform 312. The output end of the second telescopic drive member 341 is connected to a second clamping block 342, and the second clamping block 342 abuts against the side of the trim.

[0027] When the second clamping mechanism 34 is activated, several second telescopic drive members 341 extend simultaneously, pushing their respective connected second clamping blocks 342 to move towards both sides of the trim strip until the second clamping blocks 342 are in close contact with the sides of the trim strip, further securing the trim strip from the sides. At this point, the trim strip is firmly fixed to the support platform 312 under the combined action of the first clamping mechanism 33 and the second clamping mechanism 34.

[0028] The trim clamping device 3 also includes a drive assembly 32 disposed on the side of the base 311 and used to support the platform 312 to flip the trim to the bottom of the visual inspection device 2. The drive assembly 32 includes a worm gear 323 fixed on the connecting shaft 3122, and a rotary drive member 321 fixed on the base 311. The output end of the rotary drive member 321 is connected to a worm 322, which meshes with the worm gear 323.

[0029] When the trim strip is flipped over, the rotary drive 321 starts and rotates, driving the worm gear 322 to rotate. The worm gear 322 meshes with the worm wheel 323, causing the worm wheel 323 to rotate. Since the worm wheel 323 is fixed on the connecting shaft 3122, which is connected to the support platform 312, the rotation of the worm wheel 323 drives the connecting shaft 3122 and the support platform 312 to rotate together, flipping the trim strip to the bottom of the visual inspection device 2. The transmission method of the worm gear 322 and the worm wheel 323 has self-locking properties, which can keep the support platform 312 stable after it is flipped to the designated position, preventing accidental rotation due to external forces.

[0030] The visual inspection device 2 includes a connecting column 21 vertically mounted on the top of the frame 1. A support member 22 that can move up and down is slidably mounted on the connecting column 21. The support member 22 is also provided with fixing bolts that can fix the support member 22 to the connecting column 21. A detection camera 23 is also provided at the end of the support member 22 away from the connecting column 21. The support member 22 is also provided with fixing bolts that can fix the detection camera 23 to the support member 22.

[0031] The operator first adjusts the height of the support member 22 on the connecting post 21 according to the size of the trim strip and the inspection requirements. By loosening the fixing bolts on the support member 22, the support member 22 can slide freely on the connecting post 21. After moving the support member 22 to a suitable height, the fixing bolts are tightened to fix the support member 22 on the connecting post 21.

[0032] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
