[0005] The utility model provides a plastic product detection jig, which includes:

[0006] Base;

[0007] A workpiece transfer mechanism, the workpiece transfer mechanism comprising a carrier for carrying the workpiece, and a positioning plate arranged on the carrier; the carrier is slidably connected to the base, and the positioning plate is provided with a plurality of positioning parts along the sliding direction of the carrier;

[0008] A positioning member, the positioning member is arranged at one side of the workpiece transfer mechanism, and the head of the positioning member can be moved close to or away from the positioning plate perpendicular to the sliding direction of the carrier, so as to abut against the plate surface of the positioning plate facing the positioning member or a positioning portion;

[0009] The detection mechanism includes an electronic magnifying glass connected to the host computer. When the head of the positioning member abuts against a positioning portion, at least one position to be inspected of the workpiece carried on the carrier is under the lens of the electronic magnifying glass.

[0010] As a further description of the above technical solution, a contoured groove is provided on the end surface of the carrier facing away from the base to accommodate the workpiece.

[0011] As a further description of the above technical solution, the positioning member includes a damping portion, and the damping portion is connected to a side of the head portion away from the positioning plate through a pin shaft.

The following describes the implementation method of the present utility model based on its overall structure.

[0024] See also Figure 1 to Figure 2 One embodiment of the utility model discloses a plastic product inspection jig, the plastic product inspection jig comprising:

[0025] Base 1;

[0026] A workpiece 2 transfer mechanism, the workpiece 2 transfer mechanism comprises a carrier 3 for carrying the workpiece 2, and a positioning plate 4 arranged on the carrier 3; the carrier 3 is slidably connected to the base 1, and the positioning plate 4 is provided with a plurality of positioning portions 41 along the sliding direction of the carrier 3;

[0027] A positioning member 5, the positioning member 5 is arranged on one side of the workpiece 2 transfer mechanism, and its head 51 can be perpendicular to the sliding direction of the carrier 3 and approach or move away from the positioning plate 4, so as to abut against the plate surface of the positioning plate 4 facing the positioning member 5 or a positioning portion 41;

[0028] The detection mechanism includes an electronic magnifying glass 6 connected to the host computer. When the head 51 of the positioning member 5 abuts against a positioning portion 41 , at least one position to be inspected of the workpiece 2 carried on the carrier 3 is under the lens of the electronic magnifying glass 6 .

[0029] In the above-mentioned setting, the workpiece 2 transfer mechanism includes a carrier 3 for carrying the workpiece 2 (plastic product). As the carrier 3 slides relative to the base 1, the positions to be inspected of the workpiece 2 carried thereon will move one by one under the lens of the electronic magnifying glass 6 connected to the host computer, so that multiple positions to be inspected on a workpiece 2 can be magnified according to actual needs before inspection, thereby ensuring the effectiveness of the appearance inspection of the workpiece 2 and avoiding poor shipment of the workpiece 2 due to minor defects on the surface. During the inspection process, in order to ensure that each position to be inspected of the workpiece 2 is not missed, a positioning member 5 is also provided on one side of the workpiece 2 transfer mechanism, and its head 51 can be relatively close to / away from the positioning plate 4 provided on the carrier 3 perpendicular to the sliding direction of the carrier 3, thereby The positioning plate 4 is abutted against the plate surface or a positioning portion 41 of the positioning member 5. When the head 51 of the positioning member 5 abuts against a positioning portion 41, at least one of the positions to be inspected of the workpiece 2 carried on the carrier 3 is under the lens of the electronic magnifying glass 6 and can be magnified and inspected. The multiple positioning portions 41 provided on the positioning plate 4 are arranged along the sliding direction of the carrier 3. Therefore, in the process of the carrier 3 sliding along the preset direction after carrying the workpiece 2, the positioning member 5 will abut against the multiple positioning portions 41 provided on the positioning plate 4 one by one to position the carrier 3 one by one, thereby ensuring that all the positions to be inspected of the workpiece 2 carried by it are subjected to fixed-point partitioned inspection along the conveying direction of the workpiece 2, avoiding the occurrence of missed inspection of the positions to be inspected, and ensuring the quality rate of shipment.

[0030] See also Figure 1 and Figure 2 Specifically, in this embodiment, the main body of the base 1 is in a rectangular shape, and its length direction is the left-right direction. A first sliding portion 11 is provided on it along the left-right direction, and a second sliding portion 33 is provided on the lower end surface of the carrier 3. The second sliding portion 33 is slidably connected to the front and rear end surfaces of the first sliding portion 11 along the left-right direction, so that the carrier 3 can slide along the left-right direction relative to the base 1, and the inspection points of the workpiece 2 carried thereon can be magnified by the electronic magnifying glass 6 during the sliding process of the carrier 3, thereby ensuring that the small defects on the surface of the workpiece 2 can be magnified and detected.

[0031] Specifically, in the present embodiment, in order to prevent the second sliding part 33 from accidentally detaching from the first sliding part 11 when the carrier 3 slides relative to the base 1 in the left-right direction, two columnar limit members 7 are further provided on the base 1. The two limit members 7 are respectively located at the two ends of the second sliding part 33 in the left-right direction, and their heights are higher than the bottom surface of the second sliding part 33, but higher than the top surface of the second sliding part 33. Therefore, when the carrier 3 slides relatively to the preset limit positions at the left and right ends of the base 1, the second sliding part 33 is limited at the left and right ends.

[0032] Specifically, in this embodiment, in order to facilitate manual pushing of the platform 3 to move in the left-right direction on the base 1, a handle 8 is provided at the left and right ends of the platform 3, and each handle 8 is in a "U" shape with an opening toward the platform 3, and forms a closed gripping circle with the left and right edges of the platform 3 for human hand gripping. Of course, in other embodiments, the handle 8 can also be in a semicircular shape, a T shape, etc., which is convenient for human hand gripping.

[0033] Specifically, in this embodiment, the upper end surface of the carrier 3 is provided with a profiling groove 31 and a positioning plate 4 located at the rear side of the profiling groove 31, wherein the profiling groove 31 is used to position and accommodate the workpiece 2 to be inspected, and the left and right ends of the profiling groove 31 also form a groove portion 32, which is semicircular and shares a straight edge with the profiling groove 31, and an arc edge portion protrudes outward in the left and right directions relative to the profiling groove 31, so as to facilitate the workpiece 2 to be directly placed into the profiling groove 31 manually or by a robot or to be taken out of the profiling groove 31. Of course, in other embodiments, the groove portion 32 can also be formed on other edges of the profiling groove 31 to facilitate the placement and taking of the workpiece 2. The positioning plate 4 is in the shape of a long strip arranged along the left-right direction, and its rear end surface is provided with four positioning parts 41 along the left-right direction, each of the positioning parts 41 is formed by the rear end surface of the positioning plate 4 being recessed inwardly, and is in the shape of a V-shaped groove. When the platform 3 slides relative to the base 1, the positioning parts 41 will slide one by one to the relative position of the head 51 of the positioning member 5 in the front-to-back direction, so that the top of the head 51 of the positioning member 5 is forwardly pressed into the positioning part 41. At this time, at least one to-be-inspected position of the workpiece 2 carried on the platform 3 is under the lens of the electronic magnifying glass 6 so as to be magnified and inspected. In other words, in this embodiment, the positioning plate 4 is provided with four positioning parts 41 along the sliding direction of the platform 3, so it is equivalent to that a workpiece 2 is divided into four parts in the left-right direction for appearance inspection one by one, and each part contains at least one to-be-inspected position (that is, the position of the workpiece 2 where surface burrs, pits, etc. need to be controlled). Of course, in other embodiments, other numbers of positioning portions 41 may be provided on the positioning plate 4 along the sliding direction of the carrier 3 according to the actual length of the workpiece 2, the number and distribution of the positions to be inspected, so as to ensure effective inspection of the workpiece 2.

[0034] Specifically, in this embodiment, the positioning member 5 includes a damping portion connected to the rear side of the head 51 through a pin shaft, so that when the carrier 3 slides in the left and right directions, since the damping portion (such as a spring) has elastic deformation ability, when the front side of the head 51 is opposite to the rear side plate surface of the non-positioning portion 41 of the positioning plate 4, it is against the rear side plate surface of the non-positioning portion 41 of the positioning plate 4. After the carrier 3 is subjected to force and continues to move in the left and right directions to the transition point between the rear side plate surface of the non-positioning portion 41 of the positioning plate 4 and the positioning portion 41, the damping member will be forced to move forward due to the synthetic decomposition of the force. The deformation drives the head 51 of the positioning member 5 to move forward and press into the positioning portion 41 to limit the positioning plate 4, so that the position to be measured of the workpiece 2 carried by the carrier 3 is under the lens of the electronic magnifying glass 6 and can be magnified and detected. After the detection is completed, the carrier 3 is pushed and pulled in the left and right directions. Through the synthetic decomposition of the force, the damping member is forced to be compressed backward, driving the head 51 of the positioning member 5 to squeeze out the positioning portion 41, so that the carrier 3 can continue to move in the left and right directions, so that the next part of the workpiece 2 can be transferred to the electronic magnifying glass 6 for magnification detection. Preferably, in this embodiment, the positioning member 5 can use a bearing bracket type roller plunger, model TBPJ1A, which can be directly purchased from the market, and the head 51 corresponds to the front end roller of the roller plunger, and the front end roller can rotate horizontally relative to the main body of the roller plunger, thereby ensuring that it is a dynamic friction when it presses against the rear end plate surface of the positioning plate 4, and ensuring the smoothness of the movement of the carrier 3 in the direction of action.

[0035] Specifically, in this embodiment, in order to facilitate manual pushing of the carrier 3 to slide in the left-right direction, the detection mechanism and the positioning member 5 are both arranged on the rear side of the workpiece 2 transfer mechanism.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not limited to the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any changes, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
