Detailed implementation manners
[0024] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0025] As Figures 1-5 shown, the electronic product accessory detection mechanism 100 in an embodiment of the present utility model is applied to an electronic product assembly device and is used to detect whether there is a situation of missing or overlapping accessory pasting during the electronic product assembly process. The electronic product accessory detection mechanism 100 includes a frame 10, at least one moving module 20, and a detection module 30. The frame 10 is used to provide an installation position for the moving module 20 and the detection module 30. The moving module 20 is arranged on the frame 10 and includes a support platform 21 for placing the electronic product to be tested, and the support platform 21 is movably arranged on the frame 10. The detection module 30 is arranged on the frame 10 and includes a laser measuring instrument 31 arranged above the support platform 21 ( Figure 2 and 3 The triangular area A in is intended to show the irradiation angle or range of the laser measuring instrument 31).
[0026] During the actual working process, after placing an accessory (such as a sponge, a silicone pad, etc.) at the target position of the electronic product to be tested, a height difference will be generated between the target position where the accessory is pasted and the adjacent positions. Subsequently, the electronic product to be tested is placed on the support platform 21 and moves towards the downstream end. During the movement, the laser measuring instrument 31 is used to measure the height difference at the accessory position. When there is a situation of missing or multiple pasting, there is a difference between the height difference measured by the laser measuring instrument 31 and the preset data, so as to judge whether there is a situation of missing or overlapping accessory pasting.
[0027] The embodiments of the present utility model adopt high-precision laser detection equipment, and its detection accuracy range is ±0.01 mm. Therefore, compared with manual detection or other vision devices, the detection module 30 can completely detect the cases of missing labels and duplicate labels. Especially when there are duplicate labels, it can accurately detect the number of duplicate labels for the subsequent-end equipment to process.
[0028] In the embodiment as Figure 3 shown, two sets of moving modules 20 are arranged on the frame 10. The laser measuring instrument 31 can move back and forth above the two sets of moving modules 20, and its moving direction can be perpendicular to the moving direction of the support platform 21. Of course, more moving modules 20 can also be arranged on the frame 10 to increase the number of electronic products transmitted, and improve the production and detection efficiency.
[0029] The two ends of the moving module 20 are respectively the loading end for fixing the electronic product to the support platform 21, and the unloading end for removing the electronic product. In the embodiment as Figure 2 shown, the moving module 20 can be designed as follows: the moving directions of the support platforms 21 in the two sets of moving modules 20 are opposite. That is, when one support platform 21 transmits the electronic product to the unloading end, the laser measuring instrument 31 is located above this support platform 21 and is ready to detect the electronic product. At this time, the support platform 21 on the other side has completed an operation of transmitting an electronic product, and it moves towards the loading end direction to receive the next electronic product to be detected. Subsequently, the laser measuring instrument 31 moves towards the other moving module 20 direction and is ready to detect the electronic product to be detected that is re-fixed on the support platform 21 in this moving module 20, and so on.
[0030] It should be understood that since the laser measuring instrument 31 can only detect the electronic products on one set of moving modules 20 at the same time, when more moving modules 20 are set, the moving modules 20 need to be designed such that at the same time, there is and only one set of moving modules 20 whose support platform 21 passes through the laser measuring instrument 31 along the direction of the unloading end.
[0031] In one embodiment, the detection module 30 further includes a gantry 32 supported on the frame 10. The gantry 32 includes two longitudinal beams 321 fixed on both sides of the frame 10, and a cross beam 322 arranged between the two longitudinal beams 321. One or more moving modules 20 are arranged between the two longitudinal beams 321. The laser measuring instrument 31 is installed on the cross beam 322 and can move back and forth 20 on the cross beam 322 to detect the electronic products to be detected on the support platforms 21 in multiple moving modules 20.
[0032] Specifically, the detection module 30 further includes a first rail 33, a first slider 34, a first motor 35, and a first lead screw 36. The first rail 33 is fixed to the top surface of the cross beam 322. The two ends of the first lead screw 36 are supported at both ends of the first rail 33 and can rotate around its own axis. The first motor 35 is fixed to the gantry 32, and is connected to and drives the first lead screw 36 to rotate. The first slider 34 is limited and moves within the first rail 33, and is in threaded cooperation with the first lead screw 36. The laser measuring instrument 31 is fixed to the first slider 34. Therefore, driven by the first motor 35, the first lead screw 36 rotates, and under the action of the thread, the first slider 34 moves within the first rail 33 to drive the laser measuring instrument 31 to move along the first rail 33.
[0033] Preferably, first buffer columns 39 are respectively arranged at both ends of the cross beam 322. The two first buffer columns 39 cooperate to define the moving range of the laser measuring instrument 31 and provide buffering for the movement of the laser measuring instrument 31 to avoid rigid contact.
[0034] Further, the detection module 30 further includes a third rail 37 fixed to the side surface of the cross beam 322, and a third slider 38 supported and moving on the third rail 37. The third slider 38 is simultaneously connected to the first slider 34 and the laser measuring instrument 31, and is used to improve the stability of the entire laser measuring instrument 31 during movement, prevent measurement deviation of the laser measuring instrument 31 caused by shaking, and affect the detection result.
[0035] Similar to the moving mode of the detection module 30, the moving module 20 includes a second rail 22, a second lead screw 23, a second slider 24, and a second motor 25. The second rail 22 is arranged between the longitudinal beams 321 and below the cross beam 322, and extends in a direction perpendicular to the cross beam 322. The two ends of the second lead screw 23 are supported at both ends of the second rail 22 and can rotate around its own axis. The second slider 24 is limited and moves within the second rail 22, and the support platform 21 is fixed to the second slider 24. The second motor 25 is fixed to the frame 10, and is connected to and drives the second lead screw 23 to rotate. Under the action of the thread, the second slider 24 drives the support platform 21 to move within the range of the second rail 22.
[0036] Preferably, second buffer columns 26 are respectively arranged at both ends of the second rail 22, which are used to define the moving range of the support platform 21 and provide buffering for it at the same time to avoid rigid contact.
[0037] In one embodiment, to improve the stability during operation and prevent dust or other particulate matters (such as abnormally dropped auxiliary materials) from falling into the second rail 22 and affecting the operation of the moving module, a positioning plate 27 is arranged above the second rail 22 (for easy display, Figure 2(The positioning plate 27 included in the left moving module 20 on the left side is hidden). The positioning plate 27 has an inverted U-shaped cross-section and is buckled above the second track 22. It includes a cover plate 271 and side plates 272 extending downward from both sides of the cover plate 271. A positioning block 28 is fixed on the second slider 24. It includes a main body part 281 connecting the second slider 24 and connecting parts 282 extending from both sides of the main body part 281. The connecting parts 282 extend to the outside of the positioning plate 27 and then extend upward above the positioning plate 27. The support platform 21 is fixed on the connecting parts 282. As Figure 5 shown, a groove 283 is formed between the main body part 281 and the connecting parts 282. The cover plate 271 is arranged between the connecting parts 282, and the side plates 272 extend into the groove 283 to form a structure that is buckled with each other.
[0038] In one embodiment, the support platform 21 fixes the electronic product to be tested by adsorption. That is, a plurality of adsorption holes 29 are arranged on the support platform 21, and the electronic product to be tested is fixed on the surface of the support platform 21 by generating suction through an external negative pressure source. Compared with other fixing methods, the adsorption fixing method does not need to consider the size specifications of the electronic product to be tested. It only needs to set the surface of the support platform 21 into a relatively flat plane, and the flexibility is relatively high.
[0039] As Figure 1 shown, a housing 11 is detachably fixed on the frame 10. The moving module 20 and the detection module 30 are integrally fixed on the housing 11. The two are fixed to the frame 10 through the housing 11. Therefore, the disassembly and assembly can be carried out separately or integrally, and the flexibility is relatively high.
