Description

Technical Field

[0001] This utility model belongs to the field of hot air gun technology, specifically relating to a hot air gun control device and heating device. Background Technology

[0002] The hot air gun generates airflow through a miniature blower. After being heated by the heating wire, the airflow becomes a high-temperature airflow. When the high-temperature airflow is blown onto the workpiece to be heated (such as heat shrink tubing), it can be heated and tightened.

[0003] Currently, the most common type of hot air gun is the handheld hot air gun, which requires the operator to hold the gun and manually control the distance between the hot air gun and the workpiece to be heated. This handheld method makes it impossible to precisely control the distance between the hot air gun and the workpiece, resulting in poor heating performance.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a hot air gun control device, which solves the problem that handheld hot air guns cannot accurately control the distance between themselves and the workpiece to be heated.

[0006] To achieve the above objectives, a specific embodiment of this utility model provides a hot air gun control device, which includes a worktable, a lifting assembly, and a clamping assembly. The worktable includes a bearing area for supporting the workpiece to be heated. The lifting assembly includes a guide portion and a lifting portion movably disposed on the guide portion, the lifting portion being located above the worktable. The clamping assembly is disposed on the lifting portion and includes two clamping portions disposed opposite each other for clamping the hot air gun. When the lifting portion moves along the guide portion, the distance between the hot air gun and the bearing area of ​​the worktable can be changed.

[0009] In one or more embodiments of this utility model, the height of the top surface of the temperature sensor is less than or equal to the height of the top surface of the bearing area.

[0010] In one or more embodiments of this utility model, the hot air gun control device further includes a controller, which is electrically connected to the lifting assembly and the temperature sensor. The controller is used to control the moving distance and moving direction of the lifting part based on the temperature difference, where the temperature difference is the numerical difference between a preset temperature threshold and the temperature detected by the temperature sensor.

[0011] In one or more embodiments of this utility model, the two surfaces of the two clamping parts arranged opposite to each other are configured as two arc surfaces.

[0012] In one or more embodiments of this utility model, the two clamping parts are configured as an arc-shaped structure.

[0013] In one or more embodiments of this utility model, the guide portion extends in a vertical direction.

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "top", "bottom", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "second" and "first" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "second" or "first" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In one embodiment, reference is made to Figure 1 As shown, this utility model provides a hot air gun control device, which includes a worktable 1, a lifting assembly 2, and a clamping assembly 3.

[0024] Specifically, the worktable 1 includes a bearing area for supporting the workpiece to be heated. The lifting assembly 2 includes a guide portion 21 and a lifting portion 22. The guide portion 21 is disposed on the worktable 1 and extends generally in a vertical direction. The lifting portion 22 is movably disposed on the guide portion 21 and located above the bearing area. The clamping assembly 3 is disposed on the lifting portion 22 and includes two clamping portions 31. The two clamping portions 31 are arranged opposite each other generally in a horizontal direction. By adjusting the distance between the two clamping portions 31, the two clamping portions 31 can be controlled to simultaneously move closer to the hot air gun 6 or simultaneously move away from the hot air gun 6, thereby controlling the two clamping portions 31 to clamp or release the hot air gun 6.

[0025] After the hot air gun 6 is clamped and fixed by the two clamping parts 31, the hot air gun 6 can move synchronously with the lifting part 22, change the distance between the hot air gun 6 and the bearing area of ​​the worktable 1, and thus adjust the distance between the hot air gun 6 and the workpiece to be heated, so as to realize the automated and precise adjustment of the heating distance.

[0026] In one embodiment, reference is made to Figure 1 As shown, the hot air gun control device also includes a temperature sensor 4, which is located in the bearing area of ​​the workbench 1 and is used to detect the temperature around the workpiece to be heated, so that the operator can adjust the distance between the hot air gun 6 and the workpiece to be heated according to the detected temperature.

[0027] Furthermore, the hot air gun control device also includes a controller 5, which is used to control the moving distance and moving direction of the lifting unit 22, thereby further improving the accuracy of adjusting the heating spacing.

[0028] In practical applications, a temperature threshold for the workpiece to be heated can be preset. When the controller 5 receives the detected temperature transmitted by the temperature sensor 4, its built-in program compares the temperature threshold and the detected temperature, and issues corresponding control commands based on the temperature difference between the two to control the moving direction and moving distance of the lifting unit 22.

[0029] When the temperature detected by temperature sensor 4 is lower than the temperature threshold, the control lifting unit 22 drives the hot air blower downward to bring it closer to the workpiece to be heated, thereby increasing the heating temperature of the workpiece. Conversely, the control lifting unit 22 drives the hot air blower upward to move it away from the workpiece to be heated, thereby decreasing the heating temperature of the workpiece.

[0030] Secondly, based on the above control logic, the moving distance of the lifting unit 22 can also be controlled according to the absolute value of the temperature difference.

[0031] Specifically, when the absolute value of the temperature difference is small, the controller 5 can control the lifting unit 22 to move a relatively small distance. When the absolute value of the temperature difference is large, the controller 5 can control the lifting unit 22 to move a relatively large distance.

[0032] As an example, when the preset temperature threshold is 150°C and the temperature detected by the temperature sensor 4 is 140°C, the controller 5 can control the lifting part 22 to move downward by 2cm.

[0033] As another example, when the preset temperature threshold is 150°C and the temperature detected by the temperature sensor 4 is 135°C, the controller 5 can control the lifting part 22 to move downward by 3cm.

[0034] As another example, when the preset temperature threshold is 150°C and the temperature detected by the temperature sensor 4 is 155°C, the controller 5 can control the lifting part 22 to move upward by 1cm.

[0035] In one embodiment, reference is made to Figure 1 As shown, the bearing area of ​​the workbench 1 is recessed with a receiving groove 11, and the temperature sensor 4 is located in the receiving groove 11.

[0036] Furthermore, the top surface height of the temperature sensor 4 is less than or equal to the top surface height of the bearing area, so that the temperature sensor 4 is completely located within the receiving groove 11 and does not protrude from the receiving groove 11, thus avoiding an upward protruding structure in the bearing area of ​​the worktable 1.

[0037] In one embodiment, reference is made to Figure 1 As shown, the two clamping parts 31 are constructed as arc-shaped structures, and the two surfaces of the two clamping parts 31 that are arranged opposite to each other are set as two arc surfaces, that is, the inner surface of the two clamping parts 31 is an arc surface. The shape of the arc surface is adapted to the shape of the circumferential surface of the hot air gun 6 to increase the contact area between the clamping parts 31 and the hot air gun 6 and improve the clamping effect of the clamping parts 31 on the hot air gun 6.

[0038] In other embodiments, the two clamping parts 31 may also be configured in other shapes, which can be adaptively adjusted according to the actual shape of the hot air gun 6, so that the two clamping parts 31 can stably clamp the hot air gun 6.

[0039] In one embodiment, the two clamping parts 31 can be connected together by bolts or other structures. When connected by bolts, the distance between the two clamping parts 31 can be adjusted by turning the bolts, thereby adjusting the clamping force applied to the hot air gun 6.

[0040] In other embodiments, linear drive elements such as cylinders or hydraulic cylinders can also be used to automatically control the distance between the two clamping parts 31.

[0041] In one embodiment, the lifting assembly 2 may be configured as a lead screw and nut structure, a gear and rack structure, a hydraulic cylinder structure, a pneumatic cylinder structure, or a linear motor.

[0042] Preferably, in order to improve the control accuracy of the lifting assembly 2 on the position of the hot air gun 6, the lifting assembly 2 is made of a linear motor, with the linear motor guide rail as the guide part 21 and the moving part of the linear motor as the lifting part 22.

[0043] In one embodiment, reference is made to Figure 1 As shown, the present invention also provides a heating device, which includes a hot air gun control device and a hot air gun 6 in the above embodiments. The hot air gun 6 is disposed between two clamping parts 31, and the air outlet of the hot air gun 6 faces the bearing area of ​​the workbench 1.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
