Description

Technical Field

[0001] The utility model relates to the technical field of automobile cable assembly, and specifically relates to an anti-misassembly detection device for the combined joint of an automobile cable. Background Art

[0002] The structures of the combined joints of automobile cables are different. For example, for a combined joint without a cable assembled, there is an elastically deformable plastic ball bowl at one axial end of a generally circular joint body. The central hole of the plastic ball bowl is used to engage and be clamped with the ball head of the mating part that is expanded. The other axial end of the generally circular joint body is a circular convex column.

[0003] However, during the actual ultrasonic welding process of assembly, miswelding sometimes occurs, that is, the plastic ball bowl is welded to death and has no elasticity, so that the cable ball head cannot be inserted into the central hole of the plastic ball bowl, and it belongs to unqualified products.

[0004] To prevent unqualified products from entering the next process, each of the above-mentioned combined joints of automobile cables needs to be detected. The prior art uses manual detection. One hand holds the combined joint of the cable, and the other hand uses a dial post with a diameter smaller than the central hole of the plastic ball bowl to insert into the central hole of the plastic ball bowl and拨动 the plastic ball bowl. If it can be拨动 to make it contract, it is qualified; if it cannot be拨动, it is unqualified. The detection method of the prior art has a slow detection speed and low detection efficiency; and it varies from person to person, and there is a phenomenon that a qualified product should be拨动 but is not拨动 due to reasons such as small force, that is, there is a phenomenon of regarding a qualified product as an unqualified product, and the detection accuracy needs to be improved. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an anti-misassembly detection device for the combined joint of an automobile cable that can improve the detection speed, detection efficiency and detection accuracy.

[0006] The technical solution of the utility model is to provide an anti-misassembly detection device for the combined joint of an automobile cable, which includes a power switch and a bracket fixed on the tabletop of a workbench. A vertical cylinder is fixed on the bracket, and a detection rod is fixed at the free end of the piston rod of the vertical cylinder. There is a joint fixing seat below the detection rod to make the central hole of the plastic ball bowl of the combined joint coaxial with the detection rod; it also includes a control switch for manually returning the detection rod to its original position.

[0007] With the above structure, this utility model of an automotive cable combination joint error-proof detection device has the following advantages: When testing is required, after placing the combination joint to be tested, the power switch (such as the microswitch on the bracket) is turned on, and the piston rod of the vertical cylinder presses down. The pressing pressure can be set to 50N-80N. It can be visually observed whether the detection rod is inserted into the predetermined depth of the center hole and pauses slightly (e.g., one second), or stops on the surface of the center hole of the plastic ball cup, thus determining whether the product is qualified. Then, the control switch is manually turned to return the detection rod to its original position, and the combination joint is removed by hand, with qualified and unqualified products placed separately. Using this detection device to test combination joints improves the testing speed and efficiency, and has a high detection accuracy. Moreover, this detection device has a simple structure and is easy to operate.

[0008] Furthermore, the present invention's automotive cable combination joint error-proofing detection device also includes a main controller that controls the detection rod to press down for detection, controls the detection rod to return to its original position when it reaches a predetermined depth, and controls the detection rod not to return to its original position when it does not reach the predetermined depth, while simultaneously controlling the alarm to sound. With this structure, because the detection process is controlled by the main controller, if the detection rod reaches the predetermined depth, the combination joint is qualified, and the detection rod fixed to the free end of the piston rod automatically returns to its original position. If the detection rod fails to reach the predetermined depth, it does not retract, and the alarm sounds. A manual activation of the control switch then returns the detection rod fixed to the free end of the piston rod, and the combination joint is manually removed, with qualified and unqualified products placed separately. With this structure, the automation level of the detection process is significantly improved, greatly increasing the detection speed and efficiency, and the detection accuracy is also higher.

[0009] Furthermore, the detection rod is circular and a stepped column that is wider at the top and narrower at the bottom. The height of the lower section, the smaller diameter column, is the depth of the center hole of the plastic ball cup in the insertion connector. The diameter of the smaller diameter column is within the range of 0.5-2 mm larger than the inner diameter of the center hole of the plastic ball cup in the combined connector. This specific structure of the detection rod further ensures a significant increase in detection speed and efficiency, high detection accuracy, and a simple and convenient detection device structure.

[0010] Furthermore, the connector fixing seat is a cylindrical seat, with the inner hole of the cylinder matching the lower circular dimension of the combined connector and radially limiting it, ensuring that the axis of the center hole of the plastic ball cup of the combined connector and the axis of the detection rod are on the same vertical line. The above-mentioned specific structure of the connector fixing seat further guarantees the technical effects of significantly improving detection speed and efficiency, high detection accuracy, simple detection device structure, and convenient operation.

[0011] Furthermore, the connector mounting base has a fixing structure to prevent the test rod from driving the combined connector when it returns to its upward position. With this structure, the test rod will not drive the combined connector when it returns to its upward position, making the testing process smoother and more stable.

[0012] Furthermore, the support is an L-shaped plate, with two vertical through holes on the vertical plate for adjusting the cylinder height by moving screws up and down. With this structure, the cylinder height can be adjusted according to the height of the assembled joint being tested, making the testing device more adaptable to cable assembled joints of different models, specifications, and heights, thus enhancing its versatility.

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of specific embodiments are intended to aid in understanding this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various specific embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown.

[0031] An embodiment of the combined joint error-proof detection device for automotive cables of this utility model includes a power switch, such as a microswitch mounted on a bracket, and a bracket fixed to the table surface 111 of a workbench 1. The workbench 1 can be a tall, rectangular frame. A vertical cylinder 3 is fixed to the bracket, for example, by multiple screws. The free end of the piston rod 31 of the vertical cylinder 3 is fixed, for example, by welding or sleeve, to a detection rod 4 by screws. The piston rod 31 can be coaxial with the detection rod 4. Below the detection rod 4 is a joint fixing seat 7 that makes the center hole 811 of the plastic ball cup 81 of the combined joint 8 coaxial with the detection rod 4. The table surface 111 is the top surface of the top plate 11 of the workbench 1. The center hole 811 of the plastic ball cup can also be described as the center hole of the plastic ball cup 81.

[0032] It is easy to understand that the preferred embodiment of the combined joint error prevention detection device for automobile cables of this utility model also includes an air pump 51 and an electromagnetic reversing valve 52 fixed on the table surface 111 of the workbench 1. A pressure gauge 511 can be connected to the air pump 51. The air pump 51, the electromagnetic reversing valve 52, and the first air port 32 and the second air port 33 of the vertical cylinder 3 are connected by an air pipe, such as a soft plastic air pipe.

[0033] A preferred embodiment of the combined joint error-proofing detection device for automotive cables of this utility model further includes a main controller that controls the detection rod 4 to press down for detection, controls the detection rod 4 to return to its original position when it reaches a predetermined depth, and controls the detection rod 4 not to return to its original position and simultaneously controls the alarm to sound when it has not reached the predetermined depth. In other words, it also includes a main controller, which controls the detection rod 4 to press down for detection, controls the detection rod 4 to return to its original position when it reaches the predetermined depth, and controls the detection rod 4 not to return to its original position and controls the alarm to sound when it has not reached the predetermined depth.

[0034] Expanding on the above paragraph, the preferred embodiment of the combined joint error-proofing detection device for automotive cables of this utility model further includes a main controller that controls the detection rod 4 fixed to the free end of the piston rod 31 to press down for detection, controls the detection rod 4 fixed to the free end of the piston rod 31 to return to its original position when it reaches a predetermined depth, and does not return to its original position when it has not reached the predetermined depth, while simultaneously controlling an alarm to sound. In other words, it also includes a main controller, which controls the detection rod 4 fixed to the free end of the piston rod 31 to press down for detection, controls the detection rod 4 fixed to the free end of the piston rod 31 to return to its original position when it reaches the predetermined depth, and controls the detection rod 4 not to return to its original position and controls an alarm to sound when it has not reached the predetermined depth. The alarm can be an existing audible alarm such as a horn or a visual alarm such as a flashing red LED.

[0035] In a preferred embodiment of the combined joint error-proofing detection device for automotive cables of this utility model, a control switch 6 is also included, which is manually operated (e.g., manually toggled) to return the detection rod 4 to its original position. It is easy to understand that in the preferred embodiment including the main controller, the control switch 6 only controls the return of the detection rod 4 when a defective product is detected, that is, it only controls the return of the detection rod 4 when it has not reached the predetermined depth. In this preferred embodiment, lines 1-2 of this paragraph can be described as follows: It also includes a control switch 6 that is manually operated to return the detection rod 4, which is fixed to the free end of the piston rod 31, to its original position before reaching the predetermined depth.

[0036] The main controller can be a PLC programmable controller. The air pump 51, electromagnetic reversing valve 52, alarm, control switch 6, power micro switch and sensor mentioned above are all electrically connected to the main controller, or they can be electrically connected via relays.

[0037] The detection rod 4 can be circular and can be a stepped column with a larger upper section and a smaller lower section. The upper section, the larger diameter column 41, is axially limited, and the lower section, the smaller diameter column 42, has a height equal to the depth of the center hole 811 of the plastic ball cup 81 of the combination connector 8. The diameter of the smaller diameter column 42 of the detection rod 4 can be within the range of 0.5-2 mm larger than the inner diameter (hole diameter) of the center hole 81 of the plastic ball cup 81 of the combination connector 8. It is easy to understand that the top of the larger diameter column 41 can also have a connecting column 43. The bottom end of the connecting column 43 is integrally formed coaxially with the larger diameter column 41 and the smaller diameter column 42. The top end of the connecting column 43 can have a threaded hole 431, which is coaxially screwed and fixed with the external threaded column 311 of the free end of the piston rod 31 of the vertical cylinder 3. The larger diameter column 41 can be a regular hexagonal column.

[0038] The connector fixing seat 7 is a cylindrical seat. The inner hole 71 of the cylinder matches the size of the lower convex circular protrusion 82 of the combination connector 8 and radially limits it, so that the axis of the center hole 81 of the plastic ball cup 81 of the combination connector 8 is on the same vertical line as the axis of the detection rod 4. The corner of the bottom end of the lower convex circular protrusion 82 can be chamfered.

[0039] The connector fixing base 7 has a fixing structure to prevent the detection rod 4 from driving the combined connector 8 when it returns to its upward position. Alternatively, one or more evenly distributed magnets can be placed on the top surface of the cylinder to attract the magnetically conductive metal (such as ordinary steel) at the bottom of the combined connector; when the combined connector is removed, a little force can be applied to separate them. Another option is to have multiple limiting steel balls, spring-loaded, arranged around the top of the inner bore of the cylinder. When the lower circular part of the combined connector is inserted into the inner bore of the cylinder, it is limited by the limiting steel balls; when the combined connector is removed, a little force can be applied to separate them. Finally, multiple retaining rings can be arranged around the top of the inner bore of the cylinder. When the lower circular part of the combined connector is inserted into the inner bore of the cylinder, it is limited by the retaining rings; when the combined connector is removed, a little force can be applied to separate them. Alternatively, one or more electromagnets can be installed on the top surface of the cylinder to attract the magnetic metal, such as ordinary steel, at the bottom of the combined joint. The electromagnets are electrically connected to the main controller via a relay, and the main controller controls the electromagnets to be energized or de-energized to prevent the combined joint from being driven when the detection rod 4 returns to its upward position, or to prevent the combined joint from being attracted to the cylinder body so that it can be easily removed.

[0040] The bracket is an L-shaped plate 2. The vertical plate 21 of the L-shaped plate 2 has two vertical through holes 211 for adjusting the cylinder height with screws. When adjusting the cylinder height, first loosen the two screws, then move the cylinder up or down, and then tighten the screws. Of course, the L-shaped plate 2 can also be replaced by a separate vertical plate and a separate horizontal plate.

[0041] When inspecting each automotive cable connector 8, first place the connector 8 on the cylinder of the connector fixing seat 7, so that the lower circular protrusion 82 of the connector 8 is embedded in the inner hole 71 at the top of the cylinder and fixed by the fixing structure. Then turn on the power, such as by pressing the micro switch start button. The main controller controls the vertical cylinder 3 to drive the detection rod 4 fixed on the free end of the piston rod 31 to descend for inspection. If the detection rod 4 can descend to the predetermined depth, the main controller controls the detection rod 4 fixed on the free end of the piston rod 31 to automatically return to its original position. The qualified connector 8 is then manually removed and placed in the online equipment for the next process. If the detection rod 4 cannot reach the predetermined depth, the main controller controls the detection rod 4 not to return to its original position and simultaneously controls the alarm to sound. The detection rod 4 return control switch 6 is then manually activated to return the detection rod 4 fixed on the free end of the piston rod 31 to its original position. The unqualified connector 8 is then manually removed and placed separately, such as in a container for unqualified products.

[0042] It's easy to understand that the terms "assembly" and "combination" are interchangeable. The fixing described above can be achieved through welding or by using multiple screws.

[0043] Components or structures not marked above are not shown in the drawings, such as the power microswitch start button, main controller, alarm, relay, sensor, screw, air tube, and the fixing structure for preventing the detection rod 4 from retracting upwards and driving the combination connector 8. Some components are not marked in the drawings. The attached drawings are only illustrative; if there are any inconsistencies between the attached drawings and the text description, or between the attached drawings themselves, the text description shall prevail.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
