[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the setting of the fixing component, when the device is used, the placement rack provides a stable support platform. After the wiring harness is placed on the multiple groups of claws on one side of the placement rack, the two groups of second electric sliders are started to drive the fixing clamps to move, and the fixing clamps are lifted by two groups of lifting wheels, so that the multiple groups of fixing parts on one side of the fixing clamps are inserted into the card slots of the claws to doubly fix the wiring harness; and the friction plates in the card slots of the claws further enhance the fixing effect of the wiring harness to ensure that the wiring harness will not loosen or shift during the detection process; and when it is necessary to unlock, the two groups of second electric sliders are moved in the opposite direction, and the fixing clamps hang down along the lifting wheels. The operation is simple and convenient, which provides convenience for the removal and placement of the material replacement components, can quickly realize the fixing and unlocking of the wiring harness, and improves the efficiency and accuracy of the detection.

[0018] 2. The setting of the material changing component simplifies the material picking and placing operations. When the material needs to be changed after the test is completed, first use one group of two-way clamps to clamp the wiring harness to be tested, and then use two groups of first electric sliders to make the two-way clamps close to the detection box, and then use the screw slide and the lifting cylinder to align the other group of two-way clamps with the wiring harness to be taken out. By starting the first electric slider to control the distance between the two-way clamps and the first mounting plate, the clamping groove clamps the wiring harness, and the servo motor rotates the first mounting plate and the two groups of two-way clamps 180° so that the wiring harness to be tested is aligned with the detection position and placed. This one-time operation mode of completing material picking and placing solves the problem of cumbersome operation when traditional detection devices take out and put in wiring harnesses, and saves time. In actual production, especially when facing the situation where a large number of wiring harnesses need to be detected, it can improve detection efficiency, speed up detection progress, and meet the needs of production efficiency.

[0019] 3. Through the setting of the temperature control component, when using the device, the heating tube and the evaporator are respectively located in the first air duct and the second air duct on both sides of the detection chamber, and the air flow circulation is driven by the row fan to achieve temperature control. By starting one of the third electric telescopic rods to lower the corresponding baffle plate, the end of the air inlet duct close to the multiple groups of heating tubes or evaporators can be separated, so that the air inlet duct is separated from the first air duct or the second air duct, and the entire air duct is divided into a high-temperature air duct that realizes a high-temperature environment through the heating tube, and a low-temperature air duct that generates a low-temperature environment through the evaporator, so as to perform a dynamic thermal cycle test; this The test method causes the wiring harness to cycle between high and low temperatures to comprehensively test the high temperature resistance of the wiring harness. Compared with the traditional single temperature test method, the dynamic thermal cycle test can more accurately evaluate the quality of the wiring harness and provide a stronger guarantee for the stable operation of the printer. When the test device is not in use, by lowering two sets of baffles at the same time, the air duct can be sealed and dustproof to a certain extent, which helps to keep the air duct of the device clean and provide a good working environment for the next use. The two sets of side duct covers adopt a detachable structure, which reduces the difficulty of daily maintenance for users and improves the reliability of the entire device.

[0020] 4. Through the setting of the temperature sensor, when the device is used, the temperature sensor in the detection cavity can sense the temperature change in the detection cavity, realize real-time monitoring of the detection temperature, and transmit the data to the controller. The controller adjusts the heating tube, evaporator and compressor in the temperature control component according to the preset temperature parameters and actual temperature conditions to ensure that the detection temperature remains within the set range, thereby improving the accuracy of the detection and avoiding the influence of temperature fluctuations on the detection results.

[0021] 5. Through the setting of the visual observation window and the transparent heat-resistant glass, when using the device, a switchable closed door is provided on one side of the detection box, and a closing strip is also provided on one side of the closed door, which can provide good sealing for the detection chamber during the detection process and prevent external interference from affecting the detection results; at the same time, the user can monitor the detection process and observe the status of the wiring harness through the visual observation window, and the transparent heat-resistant glass installed in the visual observation window will not break or be damaged due to the increase in temperature, thereby avoiding possible harm to the user and improving the safety of observation.

The wiring harness 103 is clamped by the two sets of bidirectional clamps 302. The wiring harness 103 to be tested is first clamped by one set of bidirectional clamps 302, and then the wiring harness 103 to be taken out is clamped by the other set of bidirectional clamps 302. Then, the positions of the two sets of bidirectional clamps 302 are interchanged by the servo motor 301 to place the clamped wiring harness 103 to be tested at the detection position, thereby shortening the time for replacing samples. A temperature control component is provided on the periphery of the detection box 101, which can simulate the high and low temperature conditions in the actual working environment of the printer and perform dynamic high and low temperature cycle detection on the wiring harness 103.

[0047] Please refer to Figure 3 , Figure 4 and Figure 5 As shown, the material changing assembly also includes two groups of first linear guide rails 304. Two groups of first linear guide rails 304 are arranged on one side of the detection box 101. The two groups of first linear guide rails 304 can guide two groups of slidable first electric sliders 305 to move in the horizontal direction. The top of the two groups of first electric sliders 305 is installed with the same group of screw slides 306. The screw slide 306 drives the threaded slider on the screw through a driving motor 307 at one end thereof to move along another horizontal direction perpendicular to the first linear guide rail 304. The top of the threaded slider is connected to a support arm 308 by screws.

[0048] Please refer to Figure 4 and Figure 5As shown, two sets of sliding channels 312 are respectively opened at both ends of the first mounting plate 303, and one end of the two sets of bidirectional clamping claws 302 can slide along the two sets of sliding channels 312 respectively. Grooves communicating with the sliding channels 312 are also provided on both sides of the first mounting plate 303, and a first mounting portion 313 is installed on one side of the groove.

The bidirectional clamping claw 302 is provided with a clamping groove 315 on one side close to the first mounting plate 303. The inner wall of the clamping groove 315 is also provided with a serrated section 316. The serrated section 316 enhances the clamping effect of the wiring harness 103, which can not only reliably fix the wiring harness, but also effectively avoid sliding during the material replacement process, thereby ensuring the integrity of the wiring harness 103.

[0049] When the wiring harness 103 to be tested needs to be replaced after the test is completed, the wiring harness 103 to be tested will be first clamped by one of the two-way clamps 302, and then the clamped wiring harness 103 will be moved close to the test box 101 by using the two sets of first electric sliders 305. Next, the other set of two-way clamps 302 will be aligned with the wiring harness 103 to be taken out under the cooperation of the screw slide 306 and the lifting cylinder 310. At this time, the first electric slider 305 is controlled to adjust the distance between the two-way clamps 302 and the first mounting plate 303 so that the clamping groove 310 is The wire harness 103 to be taken out can be clamped, and then the servo motor 301 drives the entire first mounting plate 303 and the two sets of bidirectional clamping claws 302 to rotate 180 degrees, so that the positions of the two sets of bidirectional clamping claws 302 are interchanged to place the wire harness 103 to be tested at the testing position; this one-time operation mode of completing material taking and material placing solves the problem of cumbersome operation when the traditional testing device takes out and puts in the wire harness 103, simplifies the entire process of replacing the wire harness 103, improves work efficiency, speeds up the testing progress, and meets the demand for production efficiency.

[0050] Please refer to Figure 6 and Figure 7As shown, the fixing assembly also includes a mounting bracket 203, the placement frame 201 can be fixed on the mounting bracket 203 by means of screws, and two sets of sliding blocks 204 are provided at the bottom of the mounting bracket 203, which can slide along the second linear guide rail 205, and the second linear guide rail 205 is fixed on the first support frame 206, and the first support frame 206 is connected to two sets of vertical beams 207 by screws, and the bottom ends of the two sets of vertical beams 207 are respectively installed with two sets of first bases 208, and the two sets of first bases 208 are connected to the bottom of the detection chamber 102. At the same time, the two sets of vertical beams 207 are also installed on the inner wall of the detection chamber 102, and the tops of the two sets of vertical beams 207 are also fixed with the same set of first bases. A second support frame 209 is provided with a second mounting portion 210 on one side of the second support frame 209 corresponding to the mounting bracket 203, and a second electric telescopic rod 211 is provided on one side of the second mounting portion 210, and one end of the second electric telescopic rod 211 is connected to the mounting bracket 203; when the second electric telescopic rod 211 installed on the second support frame 209 is started, the entire mounting bracket 203 can be driven to move along the second linear guide rail 205, so that the placement rack 201 with the wiring harness 103 to be detected can be pushed into the detection cavity 102 or the placement rack 201 with the wiring harness 103 to be taken out can be pushed out of the detection cavity 102, so as to achieve smooth pushing of the placement rack 201, which is convenient for the material changing component to perform material taking and material discharge operations.

[0051] Please refer to Figure 8 , Fig. 9 and Fig.10 As shown, friction plates 212 are provided inside the slots of the multiple groups of claws 202 corresponding to the wire harness 103, which can not only enhance the fixing effect of the wire harness 103, but also ensure that the wire harness 103 will not be loose or shifted during the detection process; at the same time, a fixing clamp 213 is also provided on one side of the placement rack 201, and the other end of the fixing clamp 213 is provided with multiple groups of fixing members 214 corresponding to the multiple groups of slots, and these fixing members 214 can be respectively inserted into the multiple groups of slots, further enhancing the fixing effect of the wire harness 103; through this multiple-coordinated clamping method, the wire harness 103 can be firmly fixed to ensure its stable position, and at the same time, it can also effectively avoid displacement or deformation of the wire harness 103 during the detection process, thereby ensuring the accuracy and reliability of the test data; compared with the traditional single claw 202 or fixing block, this multi-level fixing method is more stable and reliable.

[0052] Both ends of the placement rack 201 are equipped with third linear guide rails 215, and a slidable second electric slider 216 is arranged on it. The two ends of the fixing clamp 213 are rotatably connected with the two sets of second electric sliders 216 through axle pins, so that the mobility of the fixing clamp 213 is realized; at the same time, both ends of the placement rack 201 are also provided with first protrusions 217, and the first fixing rods 218 are installed on the side corresponding to these first protrusions 217. On these first fixing rods 218, rotatable lifting wheels 219 are arranged. These two sets of lifting wheels 219 are in contact with the fixing clamp 213. When the wiring harness needs to be aligned, the fixing clamp 213 can be moved. When clamping 103, it is only necessary to start the second electric slider 216 to drive the entire fixing clamp 213 to slide along the third linear guide rail 215 until it contacts the wiring harness 103; and in this process, the two sets of lifting wheels 219 will also lift the fixing clamp 213 so that the multiple sets of fixing parts 214 on it can be smoothly inserted into the card slots of the claws 202, thereby realizing double fixation of the wiring harness 103; shaft sleeves 220 are also arranged between the lifting wheels 219 and the fixing clamp 213, and these shaft sleeves 220 enable the lifting wheels 219 to rotate smoothly without hindering the movement of the fixing clamp 213.

[0053] When it is necessary to release the fixed state of the wiring harness 103, the two sets of second electric sliders 216 are moved in the opposite direction, and the fixing clamps 213 will automatically fall down along the lifting wheels 219 to release the fixation of multiple sets of wiring harnesses 103. The operation is simple and quick, and the hanging fixing clamps 213 can also avoid the material changing component, so as not to cause any interference to its picking and placing actions; not only can the wiring harness 103 be quickly and firmly positioned, but also seamless docking can be achieved when released, ensuring the smooth operation of the material changing component and improving the efficiency of detection.

[0054] Please refer to Fig.16 , Fig.17 and Fig.18As shown, a fixing clamp 213 is provided on one side of the placement rack 201, and a first protrusion 217 and a second protrusion 221 are provided on both ends of the placement rack 201. A first fixing rod 218 is provided on one side corresponding to the two groups of first protrusions 217, and a rotatable lifting wheel 219 is provided on the two groups of first fixing rods 218 corresponding to the fixing clamp 213.

[0061] Embodiment 2:

[0062] Based on the high temperature resistant detection device for printer wire harness processing provided in the first embodiment of the present application, the second embodiment of the present application proposes a high temperature resistant detection device for printer wire harness processing. This second embodiment is only a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.

[0063] Please refer to Fig.16 , Fig.17 and Fig.18 As shown, a fixing clamp 213 is arranged on one side of the placement rack 201, and a first protrusion 217 and a second protrusion 221 are arranged at both ends of the placement rack 201. A first fixing rod 218 is arranged on the side corresponding to the two groups of first protrusions 217, and a rotatable lifting wheel 219 is also provided on these first fixing rods 218; similarly, two groups of second fixing rods 223 are also arranged on the side corresponding to the second protrusion 221, and a rotatable stabilizing wheel 224 is also installed on them. These lifting wheels 219 and stabilizing wheels 224 are used to support the fixing clamp 213. The lifting wheels 219 and stabilizing wheels 224 are supported by the upper and lower distribution of the lifting wheels 219 and the stabilizing wheels 224 to prevent the fixing clamp 213 from being loosened. When the clamp 213 is lifted, it tilts up and falls back. A sleeve 220 is also arranged between the lifting wheel 219 and the stabilizing wheel 224 and the fixed clamp 213; a friction plate 212 is installed in the card slots of the multiple groups of claws 202, which plays a role in assisting the fixation of the wiring harness 103. In addition, multiple groups of fixing parts 214 are also arranged on one side of the fixed clamp 213, which are respectively inserted into the multiple groups of card slots, further strengthening the fixing effect of the wiring harness 103; a third linear guide rail 215 is also arranged at both ends of the placement rack 201, on which a slidable second electric slider 216 is installed, and the two ends of the fixed clamp 213 are rotatably connected to the two groups of second electric sliders 216 through axle pins.

[0064] Compared with the first embodiment, which only uses two sets of lifting wheels 219 to lift and lower the fixing clamp 213, the second embodiment provides two sets of second protrusions 221 on the top of the fixing clamp 213, and provides a second fixing rod 223 on the side corresponding to the second protrusion 221, and at the same time, a rotatable stabilizing wheel 224 is provided on the two sets of second fixing rods 223, so that the lifting wheels 219 and the stabilizing wheels 224 are in contact with the fixing clamp 213; the main difference is that the fixing clamp 213 can be supported more stably by the lifting wheels 219 and the stabilizing wheels 224 being distributed up and down. In actual operation, when the fixing clamp 213 is lifted, only two sets of lifting wheels 219 and stabilizing wheels 224 are used. The fixing clip 213 may tilt up and fall back due to uneven force, and the addition of the stabilizing wheel 224 can not only effectively avoid this situation, but also make the fixing clip 213 more stable during the lifting and moving process, ensuring that the fixing clip 213 remains balanced during the lifting process without tilting or shaking. Therefore, compared with only using two sets of lifting wheels 219 to support the fixing clip 213 for lifting, the lifting wheels 219 and the stabilizing wheels 224 are used for upper and lower support, so that the stability of the fixing clip 213 can be improved, thereby better ensuring the smooth fixing and unlocking operations of the wiring harness 103; the other conditions are consistent with those in the first embodiment, so they are not repeated in this embodiment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
