Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment components, and in particular to a position deviation alarm device for a coaxial cam testing device. Background Technology

[0002] Coaxial cam testing devices are testing structures in electronic component testing and sorting systems. Specifically, Chinese Patent CN2936458Y discloses a device for high-speed testing of electronic components using cams. This device employs three cams to drive a material separating mechanism, a clamping mechanism, and a testing mechanism for material separating, clamping, and testing processes. However, because the cams are connected to the material separating mechanism and the clamping and testing mechanisms via rollers, positional deviations between the rollers and cams during actual use can lead to the failure of these processes. These positional deviations are mainly caused by wear between the cams and rollers or by relative positional shifts between them. Since the cam structure and rollers are not integral but detachable, this relative positional shift between the cams and rollers can occur. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a position deviation alarm device for a coaxial cam testing device, which solves the technical problem that operators cannot promptly detect when the relative position of the cam and roller in the existing coaxial cam testing device shifts.

[0004] According to an embodiment of the present invention, a position deviation alarm device for a coaxial cam testing device is described. The coaxial cam testing device includes a cam mechanism and a material separating mechanism, a material clamping mechanism, and a detection mechanism disposed on one side of the cam mechanism. The cam mechanism includes a material separating cam, a material clamping cam, and a detection cam that are respectively connected to the material separating mechanism, the material clamping mechanism, and the detection mechanism.

[0005] Rollers are provided at the connection points of the material separating mechanism, the material clamping mechanism and the detection mechanism, as well as the material separating cam, the material clamping cam and the detection cam. The material separating mechanism, the material clamping mechanism and the detection mechanism are each equipped with a position deviation alarm device.

[0006] The position deviation alarm device includes a hazard sensing switch and a failure sensing switch. The hazard sensing switch is connected to a hazard alarm light, and the failure sensing switch is connected to a failure alarm light. Each roller is provided with a hazard sensing switch and a failure sensing switch on its underside, and the failure sensing switch is located on the side closer to the cam mechanism.

[0007] The technical principle of this utility model is as follows: the material separating cam pushes the material separating mechanism to move through the roller to separate the material; the material clamping cam pushes the material clamping mechanism to move through the roller to clamp the material; the detection cam pushes the detection mechanism to move through the roller to detect the electronic components at the clamping point.

[0008] When the positions of the material separating cam, clamping cam, detection cam, and roller are normal, the roller will be detected by the danger sensing switch and failure sensing switch at its position furthest from the cam mechanism.

[0009] When there is a slight misalignment between the positions of the material separating cam, the clamping cam, the detection cam, and the roller, the roller will not be detected by the hazard sensing switch at its position furthest from the cam mechanism. At this time, the hazard sensing switch will close and the hazard alarm light will illuminate. However, the roller will still be detected by the failure sensing switch at its position furthest from the cam mechanism. In this case, the material separating, clamping, and detection can still work normally.

[0010] When the positions of the material separating cam, clamping cam, detection cam, and roller are severely misaligned, the roller will be at its furthest position from the cam mechanism and will not be detected by the hazard sensing switch and failure sensing switch. At this time, the hazard alarm light and failure alarm light will light up simultaneously, and the material separating, clamping, and detection will fail and cannot complete their work.

[0011] During normal use, the hazard warning lights and failure warning lights will flash regularly due to the movement of the cam. When there is a slight deviation, the hazard warning lights and failure warning lights will remain on.

[0012] Compared with the prior art, this utility model has the following beneficial effects: by combining the hazard sensing switch and the failure sensing switch with the hazard alarm light and the failure alarm light, it solves the technical problem that the operator cannot know in time when the relative position of the cam and the roller of the existing coaxial cam test device is offset.

[0013] Furthermore, each roller is provided with an alarm support plate on its underside, and the alarm support plate is supported by a support frame on its underside. Both the hazard sensing switch and the failure sensing switch are located on the alarm support plate.

[0014] Furthermore, an expansion plate is provided on one side of the alarm support plate, and both the hazard alarm light and the failure alarm light are mounted on the expansion plate.

[0015] Furthermore, the alarm support plate is provided with an extension arm near the cam mechanism. The two extension arms are located on both sides of the material separating cam, clamping cam, or detection cam. An axial displacement sensing switch is provided at the point where the extension arms are close to each other. The axial displacement sensing switch is connected to an axial displacement alarm light.

[0016] Furthermore, the failure sensing switch and the failure alarm light are connected in series with an alarm horn.

[0017] Furthermore, the contact surfaces of the material separating cam, the material clamping cam, the detection cam, and the roller are convex arc structures, and the cylindrical surface of the roller is a concave arc structure, with the convex arc structure and the concave arc structure in close contact.

[0018] Furthermore, the material separating mechanism, the material clamping mechanism, and the detection mechanism are provided with a common detection support frame. The material separating mechanism, the material clamping mechanism, and the detection mechanism include a movable rod, and a roller is installed at one end of the movable rod.

[0019] The other end of the movable rod of the material separation mechanism is provided with a compression spring and a material separation structure;

[0020] The other end of the movable rod of the clamping mechanism is provided with a compression spring and a clamping structure;

[0021] The other end of the movable rod of the detection mechanism is equipped with a test column;

[0022] The material separation structure and clamping structure are provided with vertical feeding channels, and the test column is provided with vertical detection claws. The detection claws are evenly distributed spring sheets, and the spring sheets are in close contact with the test column.

[0023] Furthermore, the cam mechanism also includes a transmission rod, on which the material separating cam, clamping cam, and detection cam are all mounted. One end of the transmission rod is connected to a drive motor, and the other end is connected to an encoder. Attached Figure Description

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 The coaxial cam testing device shown includes a cam mechanism 100 and a material separating mechanism 201, a material clamping mechanism 202 and a detection mechanism 203 disposed on one side of the cam mechanism 100. The cam mechanism 100 includes a material separating cam 120, a material clamping cam 130 and a detection cam 140 respectively connected to the material separating mechanism 201, the material clamping mechanism 202 and the detection mechanism 203.

[0033] The specific material separating mechanism 201, clamping mechanism 202 and detection mechanism 203 are provided with a common detection support frame 200. The material separating mechanism 201, clamping mechanism 202 and detection mechanism 203 include a movable rod 210. A roller 220 is installed at one end of the movable rod 210. The roller 220 is in close contact with the material separating cam 120, clamping cam 130 and detection cam 140.

[0034] The other end of the movable rod 210 of the separating mechanism 201 is provided with a compression spring 230 and a separating structure 241; the other end of the movable rod 210 of the clamping mechanism 202 is provided with a compression spring 230 and a clamping structure 242; a vertical feeding channel 240 is provided at the separating structure 241 and the clamping structure 242. The separating structure 241 is used to block the electronic components falling in the feeding channel 240, while the clamping structure 242 is used to clamp the electronic components falling through the separating structure 241, so that they are temporarily fixed in the feeding channel 240, which is convenient for the detection mechanism 203 to perform detection.

[0035] The other end of the movable rod 210 of the detection mechanism 203 is provided with a test post 251. The test post 251 is provided with a vertical detection claw 250. The detection claw 250 is a uniformly distributed spring sheet 252. The spring sheet 252 is in close contact with the test post 251, so that the test post 251 can push the detection claw 250 to make it contact the pin of the electronic component, thereby realizing the detection.

[0036] The compression spring 230 and spring plate 252 mentioned above are used in conjunction with the material separating cam 120, the material clamping cam 130 and the detection cam 140, so that the roller 220 can always be in close contact with the material separating cam 120, the material clamping cam 130 and the detection cam 140.

[0037] like Figure 1 As shown, the cam mechanism 100 also includes a transmission rod 110. The material separating cam 120, the material clamping cam 130 and the detection cam 140 are all mounted on the transmission rod 110. One end of the transmission rod 110 is connected to the transmission motor 150, and the other end of the transmission rod 110 is connected to the encoder 160.

[0038] Example 1

[0039] like Figure 2-3 As shown, the material separating mechanism 201, the material clamping mechanism 202 and the detection mechanism 203 are each equipped with a position deviation alarm device 170;

[0040] The position deviation alarm device 170 includes a hazard sensing switch 301 and a failure sensing switch 302. The hazard sensing switch 301 is connected to a hazard alarm light 311, which illuminates when the hazard sensing switch 301 is turned on. The failure sensing switch 302 is connected to a failure alarm light 312, which illuminates when the failure sensing switch 302 is turned on. Each roller 220 is provided with a hazard sensing switch 301 and a failure sensing switch 302 on its underside to sense the position of the roller 220 furthest from the cam mechanism 100, and the failure sensing switch 302 is located on the side closer to the cam mechanism 100.

[0041] like Figure 3-5 As shown, each roller 220 is provided with an alarm support plate 300 on its lower side, and a support frame is provided on the lower side of the alarm support plate 300. The support frame is fixed to the detection support frame 200. Specifically, the hazard sensing switch 301 and the failure sensing switch 302 are both provided on the alarm support plate 300. An extension plate 310 is provided on one side of the alarm support plate 300, and the hazard alarm light 311 and the failure alarm light 312 are both provided on the extension plate 310.

[0042] like Figure 2-5As shown, the alarm support plate 300 is integrally formed with an extension arm 320 near the cam mechanism 100. The two extension arms 320 are located on both sides of the material separating cam 120, the clamping cam 130 or the detection cam 140. An axial displacement sensing switch 321 is provided at the point where the extension arms 320 are close to each other. The axial displacement sensing switch 321 is connected to an axial displacement alarm light 313. When the axial displacement sensing switch 321 is a pressure sensing switch, the axial displacement alarm light 313 will light up when the axial displacement sensing switch 321 contacts the material separating cam 120, the clamping cam 130 or the detection cam 140.

[0043] like Figure 2-5 As shown, the failure sensing switch 302 and the failure alarm light 312 are also connected in series with an alarm horn 314, which sounds an alarm when the coaxial cam test device completely fails.

[0044] Example 2

[0045] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the contact surfaces of the material separating cam 120, the clamping cam 130, the detection cam 140, and the roller 220 are convex arc structures 101, and the cylindrical surface of the roller 220 is a concave arc structure 221. The convex arc structure 101 and the concave arc structure 221 are in close contact. Because the cooperation between the convex arc structure 101 and the concave arc structure 221 can ensure that the material separating cam 120, the clamping cam 130, and the detection cam 140 do not have axial displacement with the roller 220, there is no need for the extension arm 320, the axial displacement sensing switch 321, and the axial displacement alarm light 313 to alarm for axial displacement.

[0046] Finally, it should be noted that 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 preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
