Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology, and in particular to a quality inspection device for irregularly shaped heating racks. Background Technology

[0002] Irregularly shaped heating racks are heating devices made of materials such as metal, mica, and ceramics as a base, combined with heating wires / films. Their core function is to convert electrical energy into heat energy to provide a stable heat source for equipment. For example, in a hair dryer, the heating wire is fixed in the air duct through a physical structure to ensure stable heating after being powered on. Electrical connections are generally made through electrode pins. During the production process, quality inspection devices are used to test the heating rack.

[0003] In existing quality inspection devices, after the heating frame is clamped and positioned, the pins need to be manually connected to the energized test piece. The two processes are carried out in separate steps, which increases the actual operation time. Furthermore, after the heating test, tensile tests are performed again with the help of other equipment, which increases the actual inspection cost and generally results in low overall inspection efficiency.

Detailed Implementation

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a quality inspection device for irregularly shaped heating racks. The quality inspection device for irregularly shaped heating racks includes a bearing component 100 and a positioning component 200. By setting the positioning component 200, the heating rack can be clamped to ensure the stability of the position of the heating rack. Then, the rapid power connection operation of the heating rack pins is beneficial to the heating test. After the heating test, the component is moved outward to realize the tensile test. No additional testing equipment is required, the cost of use is low, and the operation efficiency is higher.

[0036] Specifically, the supporting component 100 includes a base plate 101, and an infrared temperature measuring camera 102 is installed on the top of the base plate 101.

[0037] The infrared temperature measurement camera 102, model HM-TD4137T-50 / W1, has a spherical design, which can effectively measure the temperature of the heating frame. The relevant temperature measurement technology and operation are existing technologies, which are clearly known to those skilled in the art, and will not be described in detail here.

[0038] The top of the base plate 101 is recessed to accommodate the installation space requirements of the positioning component 200.

[0039] Specifically, the positioning component 200 is disposed on the top of the base plate 101, including a screw sleeve 201 located on the top of the base plate 101, a handwheel 202 fixed to the outer end of the screw sleeve 201, a locking component 203 disposed on the handwheel 202, a clamping frame 204 threadedly connected to the screw sleeve 201, a second contact terminal 204c embedded in the clamping frame 204, and a power connection component 205 disposed at the bottom of the clamping frame 204, including a fixing plate 205a fixed to the bottom of the clamping frame 204. An inner displacement plate 205b is provided, and a lever plate 205c is provided between the two displacement plates 205b. A displacement frame 205d is fixed on the outer side of the displacement plate 205b. A movable rod 205e is movably connected to the other side of the displacement frame 205d. A bearing block 205f is movably connected to the other end of the movable rod 205e. A first connector terminal 205f-1 is embedded in the top of the bearing block 205f. A locking member 206 is provided on the top of the clamping frame 204. A rotating rod 207 is movably connected inside the screw sleeve 201.

[0040] There are two threaded sleeves 201, and the threads on the two threaded sleeves 201 turn in opposite directions. With this design, when the threaded sleeves 201 are driven to rotate, the two clamping brackets 204 move closer and closer when rotating forward, and move further apart when rotating backward.

[0041] Both sides of the outer ring of the threaded sleeve 201 are smooth and are mounted on the base plate 101 via bearing seats. This design can effectively improve the rotational stability of the threaded sleeve 201.

[0042] There is space between the handwheel 202 and the screw sleeve 201, and between the handwheel 202 and the rotating rod 207. The handwheel 202 and the screw sleeve 201 are fixedly connected by a support rod, as shown in the attached diagram of the instruction manual. Figure 4 As shown, the handwheel 202 allows workers to easily drive the screw sleeve 201 to rotate.

[0043] With the setting of the locking component 203, the handwheel 202, the screw sleeve 201 and the rotating rod 207 can rotate together in the locked state as the operator moves.

[0044] By setting the movable rod 205e, when the drive displacement frame 205d moves to the side, the linkage bearing block 205f moves up and down, thereby cooperating with the first contact terminal 205f-1 and the second contact terminal 204c to complete the clamping of the heating frame pins, so that when the external safety switch is turned on, the corresponding circuit is connected, and the heating frame is powered on and generates heat.

[0045] Example 2

[0046] Reference Figures 2 to 10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, one end of the displacement frame 205d passes through the fixed plate 205a and is slidably connected to the fixed plate 205a, and the lever plate 205c is fixed to the rotating rod 207.

[0048] The rotating rod 207 is movably connected to the screw sleeve 201 through the bearing. With the arrangement of the rotating rod 207 and the dial plate 205c, when the rotating rod 207 is driven to rotate, the dial plate 205c rotates synchronously and squeezes the displacement frame 205d to move outward.

[0049] A second spring 205g is fitted on the displacement frame 205d. One end of the second spring 205g is fixed to the fixed plate 205a, and the other end of the second spring 205g is fixed to the displacement frame 205d.

[0050] By setting the second spring 205g, the displacement plate 205b and the displacement frame 205d can be kept in their initial positions under the action of external force, thus preventing the displacement plate 205b and the displacement frame 205d from moving arbitrarily.

[0051] A storage groove 204b is provided on one side of the clamping frame 204. The second contact terminal 204c is fixed to the top of the inner cavity of the storage groove 204b and cooperates with the first contact terminal 205f-1. The bearing block 205f is slidably connected in the storage groove 204b. A heat-resistant pad 204d is fixed on the clamping frame 204.

[0052] The movable rod 205e extends into the storage groove 204b at one end near the support block 205f. The clamping frame 204 has a corresponding vertical groove, which is connected to the storage groove 204b to meet the movement space requirements of the movable rod 205e.

[0053] Heat-resistant pad 204d is located outside the storage slot 204b, as shown in the attached diagram in the instruction manual. Figure 8 As shown, during installation, the heat-resistant pad 204d is in contact with the heating element.

[0054] The heat-resistant pad 204d is made of perfluoroether rubber, which has extreme temperature resistance and can work stably for a long time from -39℃ to 288℃. It is suitable for the working temperature when the heating frame is powered on, and can still maintain its elasticity at high temperatures. It has extremely strong stability against acids, alkalis, amines, ketones, ethers, oxidants, organic solvents, and fuel chemicals.

[0055] The heat-resistant pad 204d can make good contact with the heating frame and produce elastic deformation, which is suitable for the operating temperature of the heating frame. The elastic design is not only suitable for the installation requirements of irregularly shaped heating frames, but also increases the contact friction with the heating frame and improves the clamping stability.

[0056] The top and bottom of the dial plate 205c are flat, while the sides are inclined. With this design, when the dial plate 205c rotates, the inclined surface will contact the displacement plate 205b and squeeze the displacement plate 205b to move until the dial plate 205c rotates 90 degrees and the flat surface contacts the displacement plate 205b, thus preventing the displacement plate 205b from moving again.

[0057] When the drive rod 207 and the screw sleeve 201 rotate together to perform the power connection operation, the drive rod 207, the screw sleeve 201 and the dial plate 205c will all rotate 90 degrees. As the displacement plate 205b moves, the clamping frame 204 will also move by a quarter pitch, and the heat-resistant pad 204d will be further compressed. At this time, the heat-resistant pad 204d plays a role in distance compensation. While ensuring stable clamping of the heating frame, it will also meet the requirement of the clamping frame 204 to move by another quarter pitch.

[0058] The mounting component 203 includes a crossbar 203a fixed to the handwheel 202, a first spring 203b sleeved on the crossbar 203a, and a locking block 203c slidably connected to the crossbar 203a.

[0059] The handwheel 202 has a groove 202a, the crossbar 203a is fixed in the groove 202a, and the locking block 203c is slidably connected in the groove 202a.

[0060] By setting the crossbar 203a, the displacement of the locking block 203c can be guided, thereby improving the stability of the locking block 203c's movement.

[0061] The first spring 203b provides elastic support for the locking block 203c, preventing the locking block 203c from shifting arbitrarily when no external force is involved.

[0062] The top of the rotating rod 207 has a slot 207a, which cooperates with the locking block 203c. One end of the first spring 203b is fixed in the groove 202a, and the other end of the first spring 203b is fixed on the locking block 203c.

[0063] By setting up the locking block 203c and the slot 207a, when the locking block 203c is inserted into the slot 207a, the handwheel 202 can be driven to rotate, which will cause the screw sleeve 201 and the rotating rod 207 to rotate together.

[0064] The locking member 206 includes a connecting frame 206a that is slidably connected to the clamping frame 204, and a clamping member 206a-1 is provided at one end of the connecting frame 206a.

[0065] The clamping frame 204 has a displacement groove 204a, which cooperates with the connecting frame 206a.

[0066] The end of the connecting frame 206a away from the clamping member 206a-1 is T-shaped, and the corresponding displacement groove 204a is also T-shaped. This design allows for flexible adjustment of the position of the connecting frame 206a to avoid affecting the normal clamping of the heating frame. At the same time, when the clamping frame 204 moves laterally, the connecting frame 206a will also move synchronously.

[0067] An auxiliary frame 103 is fixed to the top of the base plate 101. An infrared temperature measuring camera 102 is screwed onto the auxiliary frame 103. A sliding groove 101a is opened on the top of the base plate 101. An installation groove 101b is opened at the center of the outer side of the base plate 101. A hexagonal sleeve rod 202b is fixed in one handwheel 202. A hexagonal straight rod 202c is fixed in the other handwheel 202 and cooperates with the hexagonal sleeve rod 202b.

[0068] An auxiliary block is fixed at the bottom of the clamping frame 204. The auxiliary block extends into the slide groove 101a. The slide groove 101a and the auxiliary block can play a role in positioning and guiding, effectively improving the displacement stability of the clamping frame 204.

[0069] One end of the hexagonal straight rod 202c extends into the hexagonal sleeve rod 202b and slides in contact with the hexagonal sleeve rod 202b, as shown in the attached diagram of the instruction manual. Figure 9 As shown, both the lever 205c and the rotating rod 207 have through slots at their centers. The inner diameter of the through slots is larger than the specification of the hexagonal sleeve rod 202b, so that the lever 205c and the rotating rod 207 will not be affected when the hexagonal sleeve rod 202b is rotating.

[0070] By setting up the hexagonal sleeve 202b and the hexagonal straight rod 202c, when the operator drives the single handwheel 202 to rotate, the other handwheel 202 will be rotated in conjunction, so that the two screw sleeves 201 rotate synchronously in the same direction.

[0071] When in use, the heating frame is placed between the two clamping frames 204, and the drive handwheel 202 drives the screw sleeve 201 to rotate forward. Under the screw drive, the two clamping frames 204 gradually move closer to each other to complete the stable clamping of the clamping frames 204. The heat-resistant pad 204d contacts the heating frame and is compressed.

[0072] The heating bracket pins are placed in the storage slot 204b and located between the second contact terminal 204c and the first contact terminal 205f-1. After the clamping bracket 204 is stably clamped, the moving block 203c is placed into the slot 207a, and the first spring 203b is compressed.

[0073] Then, drive the handwheel 202 to rotate further, and the linkage lever 207 and the dial plate 205c rotate 90 degrees, so that the dial plate 205c presses the displacement plate 205b to move, and the displacement frame 205d moves together. The second spring 205g is compressed. With the cooperation of the movable rod 205e, the bearing block 205f can move upward in the storage groove 204b. The first contact terminal 205f-1 and the second contact terminal 204c complete the stable clamping of the pin.

[0074] When the pins of the heating frame are in close contact with the first connector terminal 205f-1 and the second connector terminal 204c, the circuit they are in is connected, and the safety switch of the control peripheral is connected, which enables the heating frame to be powered on and heated, and infrared temperature measurement is performed by the infrared temperature measuring camera 102.

[0075] When a tensile test is required, the heating component on the heating frame is clamped in advance with the clamping piece 206a-1 before the heating frame heats up. Then, the handwheel 202 is driven to reverse so as to provide tensile force. The infrared temperature measuring camera 102 can also take pictures to observe the degree of tensile deformation of the heating component.

[0076] Example 3

[0077] Reference Figures 5-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0078] Specifically, as the usage time increases, the bearing between the screw sleeve 201 and the rotating rod 207 gradually becomes blocked. This can be prevented by adding lubricating oil, thus avoiding the screw sleeve 201 from rotating and causing the rotating rod 207 to rotate. Furthermore, even if the rotating rod 207 rotates due to a small friction force when the locking block 203c is not inserted into the locking slot 207a, the dial plate 205c will rotate and contact the fixing plate 205a. Under the elastic support of the second spring 205g, the displacement plate 205b is maintained in its position. The dial plate 205c and the rotating rod 207 will not rotate excessively, so that the first contact terminal 205f-1 and the second contact terminal 204c will not be connected to the heating frame pins, thus improving operational safety.

[0079] Clamping component 206a-1 includes a fixed clamping block, a movable clamping block, and an auxiliary screw, as shown in the attached diagram of the instruction manual. Figure 5As shown, the fixed clamping block is fixed on the connecting frame 206a, the auxiliary screw is movably connected inside the connecting frame 206a, and the movable clamping block is threadedly connected to the auxiliary screw and slides in contact with the connecting frame 206a. With this design, when the auxiliary screw is driven to rotate, it can work with the fixed clamping block and the movable clamping block to complete the stable clamping of the heating element on the heating frame.

[0080] To simulate the working space of the heating element in a hair dryer, an arc-shaped frame can be slidably installed within the mounting slot 101b, as shown in the attached diagram of the instruction manual. Figure 10 As shown, a damping pad is fixed inside the mounting groove 101b, which contacts the arc-shaped frame to increase friction and help improve the installation stability of the arc-shaped frame.

[0081] This device has four power connection points, making it suitable not only for two-pin heating elements but also for multi-stage electric heaters and large heating elements, thus expanding its applicability.

[0082] Multi-stage electric heaters refer to heaters that require multiple control circuits to manage the power output of different heating stages. When the equipment needs to adjust the heat output in stages, four wires can be connected to the positive and negative poles of different power levels respectively, and flexible temperature adjustment can be achieved through parallel or segmented control.

[0083] Large heating elements refer to those with a large heating area or high requirements for operational stability. The four-point design provides redundant paths. If a circuit is broken due to material fracture at a certain point on the positive or negative electrode, the remaining points can still maintain conductivity, ensuring that the heating layer continues to work and avoiding overall failure due to a single point of failure.

[0084] It should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
