Description

Technical Field

[0001] The utility model relates to the field of sensors, in particular to a heating device. Background Art

[0002] Heat shrink tubing is an insulating tube that can be used on some live equipment to provide sealing, waterproofing, dustproofing and electrical insulation. Heat shrink tubing is generally made of heat shrinkable material, also known as polymer memory material, which is a combination of polymer material and radiation processing technology material and is a smart material.

[0003] At present, the heat shrink tube is fixed on some live products mainly by the operator inserting the heat shrink tube into the product, fixing the hot air gun on the table, and manually holding the product close to the hot air gun, then starting the hot air gun, and manually rotating the product during heating to make the heat shrink tube evenly heated, thereby fixing the heat shrink tube on the product. Such operation has a low degree of production automation, low production efficiency, and complex operation. The operator needs to adjust the angle of the product at all times to make the heat shrink tube evenly heated. Long-term high temperature working conditions are also prone to cause discomfort to the operator. At the same time, if the operation is improper, the operator will be in danger of being burned at any time. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the current operation process of fixing the heat shrink tube on the product is complicated, the production efficiency is low and the risk is high. The utility model provides a heating device, which can improve the production automation and production efficiency, simplify the operation, improve the operating environment, and avoid the risk of scalding.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a heating device, comprising:

[0006] platform;

[0007] A fixing plate, the fixing plate is arranged on the platform, and a product positioning tool is arranged on the fixing plate to fix the product to be heated;

[0008] A first driving part, the first driving part is connected to the fixing plate and is used to drive the fixing plate to move relative to the platform, so as to drive the product to be heated to move between the non-heating zone and the heating zone;

[0009] A heating carrier plate, the heating carrier plate can move relative to the platform to the heating zone, and a heating device is provided on the heating carrier plate;

[0010] The second driving part is arranged on the heating support plate and connected to the heating device. The second driving part is used to drive the heating device to move toward the product to be heated so as to be spaced apart from the product to be heated and heat the product to be heated.

[0011] For the convenience of description, the implementation mode of the present application is described by taking the product to be heated as a heat shrink tube and the target product as a sensor as an example.

[0012] By adopting the above technical scheme, the heat shrink tube is fixed with a product positioning tool to prevent the heat shrink tube from moving back and forth during the heating process, resulting in heating failure and affecting product quality; at the same time, the first drive unit can drive the fixed plate to move relative to the platform, so that the fixed heat shrink tube moves to the heating zone, and the heating carrier plate moves relative to the platform to the heating zone to drive the second drive unit and the heating device on the heating carrier plate to move to the heating zone, and then the second drive unit drives the heating device to move toward the heat shrink tube to heat the heat shrink tube. The first drive unit, the second drive unit and the heating carrier plate are used to ensure that the heating device and the heat shrink tube can be moved to the heating zone, so that the heating device heats the heat shrink tube in the heating zone. After heating is completed, the heating device and the heat shrink tube can be moved to the non-heating zone, so as to realize the automation of the entire heating process, without the need to manually move and rotate the heat shrink tube, thereby improving production efficiency. The operator only needs to fix the heat shrink tube on the product positioning tool, which reduces the operator's work intensity and avoids the risk of burns to the operator.

[0013] According to another specific embodiment of the present utility model, an embodiment of the present utility model discloses a heating device, wherein the fixing plate is detachably connected to the first driving part.

[0014] By adopting the above technical solution, the fixing plate is detachably connected to the first driving part. When the product model or type of the heat shrink tube / sensor changes, the fixing plate can be replaced at any time, thereby improving the applicability of the heating device.

[0015] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a heating device, wherein the heating device is connected to the heating supporting plate in a slidable manner along a vertical direction.

[0016] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a heating device, wherein the heating device comprises two heating devices, and the two heating devices are located on opposite sides of the platform along the vertical direction.

[0017] By adopting the above technical solution, two heating devices are set on opposite sides of the platform, that is, on opposite sides of the heat shrink tube, so that the heat shrink tube can be fully heated. The operator no longer needs to manually rotate the heat shrink tube to ensure uniform heating, thereby improving production efficiency and automation.

[0018] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a heating device, which also includes a smoke filtering device, which is connected to the heating support plate and can move synchronously with the heating support plate. In the heating zone, the smoke filtering device faces the product to be heated.

[0019] By adopting the above technical solution, in the heating area, the smoke filter device faces the heat shrink tube. When the heat shrink tube starts to heat up, the smoke filter device can absorb excess heat during the heating process and waste gas generated when the heat shrink tube is heated, thereby protecting the working environment.

[0020] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a heating device, wherein the heating device further comprises a camera detection mechanism, and the camera detection mechanism can move to the heating zone and take a picture of the product to be heated.

[0021] By adopting the above technical solution, after the heating is completed, the camera detection mechanism can move to the heating area to take pictures of the heat shrink tube and compare it with the sample picture in the background. When the comparison results are consistent, it means that the product is heated successfully. When the comparison results are inconsistent, it means that the heating has failed. At this time, the product will be discarded or reprocessed to ensure the quality of the product and reduce the number of defective products.

[0022] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a heating device, wherein the product to be heated is arranged on the target product, and the product positioning tooling includes a limit block and a toggle clamp mechanism, and the number of the limit blocks is multiple, and the multiple limit blocks are arranged at intervals along the extension direction of the target product, and each of the limit blocks is provided with a limit groove to accommodate the target product and limit the movement of the target product along its width direction and along its thickness direction, and the toggle clamp mechanism is arranged on at least part of the limit blocks to limit the movement of the target product along its thickness direction.

[0023] By adopting the above technical solution, after placing the sensor in the limit groove, the elbow clamp mechanism is moved toward the sensor and contacts the thermal sensor to achieve all-round fixation of the sensor, ensuring that the sensor will not move arbitrarily during the heating process, resulting in heating failure, affecting the quality of the product, and reducing the number of defective products. Similarly, when a new sensor needs to be replaced, it is only necessary to move the elbow clamp mechanism away from the sensor and remove the sensor from the limit groove to replace the new sensor. The installation, fixing and disassembly steps are simple. At the same time, a plurality of limit blocks are arranged at intervals along the extension direction of the sensor to ensure the limitation of the sensor and prevent the sensor from moving during the heating process, causing the fixed position of the heat shrink tube to deviate, affecting the quality of the product, and reducing the number of defective products.

[0024] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a heating device, wherein the product positioning tool further comprises a tensioning mechanism, and the tensioning mechanism is arranged at the first section of the target product, so as to make the target product always in a tensioned state.

[0025] By adopting the above technical solution, the tensioning mechanism can keep the sensor in a tensioned state at all times, thereby preventing bubbles from being generated at the fixing point of the heat shrink tube after the sensor becomes loose, thereby preventing the product quality from being affected.

[0026] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a heating device, wherein a handle is provided on the fixing plate.

[0027] By adopting the above technical solution and providing handles, when the fixing plate needs to be replaced, the operator only needs to lift the two handles to replace it without lifting the entire fixing plate, which is more labor-saving and simpler to operate.

[0028] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a heating device, which also includes an upper frame and a lower frame, the upper frame includes a cavity with an opening on one side, and the side of the upper frame close to the opening end is provided with safety grating sensors that are opposite to each other, the upper frame is arranged above the platform, and the lower frame is arranged below the platform.

[0029] By adopting the above technical solution, mutually radiating safety grating sensors are arranged, so that when the operator puts his hand into the cavity of the upper frame to fix the sensor, the safety grating sensor can sense the signal and transmit the signal to the PLC (Programmable Logic Controller). The PLC controls the heating equipment to put it in a non-working state to protect the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] refer to Figure 1 The embodiment of the present application provides a heating device, which can be used to heat the heat shrink tube on the sensor and fix it on the sensor, but is not limited to this. It can also be used to heat other products. For the convenience of description, the embodiment of the present application takes the product to be heated as the heat shrink tube and the target product as the sensor as an example to expand the description.

[0042] For example, continue to refer to Figure 1 A heating device comprises: a device frame 1, the device frame 1 comprises an upper and a lower layer, the upper frame 10 comprises a cavity with one side open, such as Figure 1 As shown, the upper frame 10 is in the shape of a rectangular parallelepiped, but is not limited thereto, and may also be in the shape of a square, a quadrilateral or other shapes, as long as it can accommodate the fixing plate 3 and the heating carrier plate 5 described later (refer to Figure 2 )、Smoke filter device 7 (reference Figure 4 ) and camera detection mechanism 8 (reference Figure 5 )

[0043] Exemplarily, the top, left, right and back of the upper frame 10 are all closed. Figure 1 The side facing the operator is an open end 100, and the top, left, right and back of the upper frame 10 together form a cavity with the open end 100. A safety grating sensor 102 that is mutually radiated is provided on one side of the upper frame 10 close to the open end 100. When the operator's hand enters from the open end 100, the safety grating sensor 102 can sense and transmit the signal to the PLC (Programmable Logic Controller), and the PLC controls the heating device to be in a non-working state to protect the safety of the operator.

[0044] For example, continue to refer to Figure 1 , along the third direction (i.e. Figure 1 In the Z direction shown in the figure, the upper frame 10 is located above the platform 12, or in other words, the platform 12 can carry the upper frame 10, and the lower frame 11 is located below the platform 12, or in other words, the platform 12 is placed on the lower frame 11, and a through hole 13 connecting the upper frame 10 and the lower frame 11 is provided on the platform 12.

[0045] For example, reference Figures 1 to 3 The platform 12 is provided with a first driving unit 2, which includes a driving plate 20, a first ball screw 21, a second ball screw 22, a first motor 23 and a second motor 24. The fixing plate 3 is detachably connected to the driving plate 20, and the driving plate 20 moves in a first direction (i.e. Figure 1 The first motor 23 drives the first ball screw 21 to rotate, and the second motor 24 drives the second ball screw 22 to rotate, thereby driving the drive plate 20 to rotate in the second direction (i.e., the X direction shown in the figure). Figure 1 The first ball screw 21 and the second ball screw 22 are moved in the Y direction as shown, and the circular motion of the first ball screw 21 and the second ball screw 22 is converted into the linear motion of the driving plate 20, thereby driving the fixed plate 3 to move relative to the platform 12, for example, along the second direction (i.e. Figure 1 However, the present invention does not limit the movement trajectory of the fixed plate 3, which can be as follows Figure 1 The linear movement along the second direction shown may also be a curved or diagonal movement, as long as the fixing plate 3 can be moved to the heating zone.

[0046] The embodiment of the present application does not limit the driving method for driving the fixed plate 3 to move relative to the platform 12 (i.e., the specific type of the first driving part 2). For example, the first ball screw 21, the second ball screw 22, the first motor 23 and the second motor 24 shown in the embodiment of the present application may cooperate with each other to convert the circular motion of the first ball screw 21 and the second ball screw 22 into the linear motion of the driving plate 20. It may also be a method in which a cylinder cooperates with a slider rail, etc., as long as it can achieve the goal of driving the fixed plate 3 to move relative to the platform 12.

[0047] For example, reference Figures 1 to 3 , the fixing plate 3 is along the first direction (i.e. Figure 2The fixing plate 3 is provided with two handles 30 along the first direction, and the two handles 30 are arranged at intervals along the first direction. A product positioning tool 31 is provided between the two handles 30. The product positioning tool 31 includes six limit blocks 32 arranged at intervals along the extending direction of the sensor 4, three toggle clamp mechanisms 33 arranged on the limit blocks 32 of the tail section 41 of the sensor 4, and a first section 40 (i.e. Figure 3 The tensioning mechanism 34 of the toggle clamp mechanism 33 is provided with a limit slot 35 to accommodate the sensor 4 and limit the movement of the sensor 4 along its width direction and along its thickness direction. The limit slot 35 extends along the length direction of the sensor 4 and is designed in the form of a contraction opening. The toggle clamp mechanism 33 can move in the third direction (i.e. Figure 2 The Z direction shown in the figure) moves up and down to limit the tail section 41 (i.e. Figure 3 Movement of the section from segment D to segment E) along its thickness direction.

[0048] Exemplarily, along the first direction, the tensioning mechanism 34 is arranged on both sides of the limit block 32 located at the first section 40 of the sensor 4, and a fixed shaft passing through both ends of the limit block 32 is set, and a spring is sleeved on the part of the fixed shaft away from the sensor 4.

[0049] It should be noted that the embodiment of the present application does not limit the number of limit blocks 32, elbow clamp mechanisms 33 and tensioning mechanisms 34, as long as the sensor 4 can be fixed on the fixed plate and is always in a tensioned state. For example, seven limit blocks 32, four elbow clamp mechanisms 33 and two tensioning mechanisms 34 can be set. Similarly, the embodiment of the present application does not limit the number and setting positions of the handles 30, as long as it is convenient for the operator to extract the fixed plate 3, for example, four handles 30 are set along the four sides of the fixed plate 3.

[0050] Exemplarily, that is to say, the first driving unit 2 can drive the fixing plate 3 to move relative to the platform 12, thereby driving the sensor 4 on the fixing plate 3 to move relative to the platform 12 and the heat shrink tube 42 of the tail section 41 of the sensor 4 to move between the heating area and the non-heating area, refer to Figure 3 , for example, moving from end e to end f.

[0051] Among them, reference Figure 3 and Figure 4 The heating zone can also be any position set by the program. The embodiment of the present application does not limit the specific position of the heating zone. In the application embodiment, when the heating zone is the first heating device 50 and the second heating device 52 are on the upper and lower sides of the heat shrink tube 42, the area enclosed by the heat shrink tube 42 and the first heating device 50 and the second heating device 52 is the heating zone.

[0052] For example, reference Figures 2 to 4The heating device also includes a heating carrier plate 5, which is heated along the third direction (i.e. Figure 2 The heating support plate 5 extends in the Z direction as shown in the figure and passes through the through hole 13. The heating support plate 5 is driven by the third driving part to move relative to the platform 12 to the heating zone.

[0053] For example, reference Figure 1 and Figure 4 The third driving unit is connected to the platform 12 through the supporting frame 54. The embodiment of the present application does not limit the specific structure of the third driving unit. It can be the same as the specific structure of the first driving unit 2, or the same as the structure of the second driving unit 51 described later, or include a first slide rail and a second slide rail spaced apart along the second direction, a third motor, and a third ball screw arranged between the first slide rail and the second slide rail. A first slider is provided on the first slide rail, the second slide rail and the third ball screw, and the heating supporting plate 5 is connected to the first slider. The third motor is connected to the third ball screw and drives the third ball screw to rotate. The third ball screw converts the circular motion into the linear motion of the first slider, that is, drives the first slider to move along the first slide rail and the second slide rail, so that the heating supporting plate 5 moves along the first direction.

[0054] It should be noted that the embodiment of the present application does not limit the movement trajectory of the heating support plate 5, which can be as follows: Figure 4 The first direction (i.e. Figure 4 It can be a linear motion (in the X direction shown), or a curved or diagonal motion, as long as the heating carrier plate 5 can be moved to the heating zone.

[0055] For example, reference Figures 2 to 4 A first heating device 50, a second driving unit 51, a second heating device 52 and a fourth driving unit are provided on the heating supporting plate 5. The first heating device 50 and the second heating device 52 are located on opposite sides of the platform 12 along the vertical direction (i.e., the third direction). In the heating area, the first heating device 50 and the second heating device 52 are respectively spaced apart from the heat shrink tube 42 along the third direction. The second driving unit 51 and the fourth driving unit are provided on both sides of the heating supporting plate 5 along the third direction and have the same structure. Therefore, the embodiment of the present application is described by taking the second driving unit 51 as an example.

[0056] Exemplarily, the second driving part 51 includes a first cylinder 510, a third slide rail 511, a fourth slide rail 512 and a second slider 513, the first cylinder 510 is connected to the second slider 513, and the third slide rail 511 and the fourth slide rail 512 are both along the third direction (i.e. Figure 2The first heating device 50 is connected to the second slider 513, and the first cylinder 510 drives the second slider 513 to move up and down along the third direction along the third slider 511 and the fourth slider 512. The second slider 513 drives the first heating device 50 to move synchronously, that is, the first heating device 50 moves away from the heat shrink tube (that is, along the first direction). Figure 4 d direction shown) and close to the heat shrink tube (i.e. along Figure 4 That is, the first heating device 50 is connected to the heating supporting plate 5 in a slidable manner along the vertical direction (ie, the third direction).

[0057] Similarly, when heating is required, the heating support plate 5 is driven by the third driving unit to move along the first direction (i.e. Figure 4 X direction as shown) to the heating zone (reference Figure 4 , i.e., from a to b), and then the first heating device 50, driven by the second driving unit 51, moves toward the direction close to the heat shrink tube (i.e., along the Figure 4 The second heating device 52 moves in the direction close to the heat shrink tube (i.e., along the direction c shown in FIG. 1 ), driven by the fourth driving unit. Figure 4 When the heating is completed, the first heating device 50 is driven by the second driving part 51 to move in a direction away from the heat shrink tube (i.e., along the direction d shown in FIG. 5 ). Figure 4 The second heating device 52 moves in the direction away from the heat shrink tube (i.e., along the direction d shown in FIG. 1 ), driven by the fourth driving unit. Figure 4 movement in the c direction as shown).

[0058] It should be noted that the present embodiment does not limit the movement trajectories of the first heating device 50 and the second heating device 52, which can be as follows: Figure 4 The linear motion along the third direction shown can also be a curved or diagonal motion, as long as the first heating device 50 and the second heating device 52 can be moved to the upper and lower sides of the heat shrink tube. Similarly, the embodiment of the present application does not limit the specific structure of the second drive unit 51 and the fourth drive unit, and a motor and a screw can also be coordinated.

[0059] For example, reference Figure 4 The heating device also includes a smoke filtering device 7, along the first direction (i.e. Figure 4 The smoke filter device 7 is arranged on one side of the heating support plate 5 and can move synchronously with the heating support plate 5. In the heating area, the smoke filter device 7 faces the heat shrinkable tube. When the heat shrinkable tube starts to be heated, the smoke filter device 7 can absorb the excess heat in the heating process and the exhaust gas generated when the heat shrinkable tube is heated, so as to protect the working environment.

[0060] For example, reference Figure 5 Combined with Figure 1 The heating device also includes a camera detection mechanism 8 and a fifth driving unit 9. The camera detection mechanism 8 includes an industrial camera 80 and an LED lamp 81. The fifth driving unit 9 includes a mounting plate 90, a fourth ball screw 91, an L-shaped connecting plate 92 and a fourth motor 93. The mounting plate 90 is arranged on the upper wall of the upper frame 10. The fourth ball screw 91 connects the mounting plate 90 and the fourth motor 93. The L-shaped connecting plate 92 connects the fourth ball screw 91. The industrial camera 80 and the LED lamp 81 are arranged on the L-shaped connecting plate 92. The fourth motor 93 drives the fourth ball screw 91 to rotate. The fourth ball screw 91 converts the circular motion into the linear motion of the L-shaped connecting plate 92, that is, drives the L-shaped connecting plate 92 to move along the fourth ball screw 91, so that the industrial camera 80 and the LED lamp 81 move along the first direction (i.e. Figure 5 The heat shrink tubing is moved in the X direction (as shown) to the heating zone and takes pictures of the heat shrink tubing before and after heating, which are then uploaded to the backend and compared with the pictures of OK samples (referring to qualified samples whose test parameters are within the limit range) in the backend.

[0061] It should be noted that the embodiment of the present application does not limit the motion trajectory of the camera detection mechanism 8, which can be as follows: Figure 5 The linear motion along the first direction shown can also be a curved or diagonal motion, as long as the camera detection mechanism 8 can be moved to the heating area. Similarly, the embodiment of the present application does not limit the specific structure of the fifth drive part 9, and it can also be a cylinder and a slider rail.

[0062] For example, reference Figure 1 The open end 100 of the upper frame 10 is also provided with a display 14, and a three-color light 15 is installed on the upper frame 10. If the above-mentioned comparison results are consistent, OK is displayed on the display 14, and the three-color light 15 has no response. If the above-mentioned comparison results are inconsistent, it is an NG product (referring to an unqualified product whose test parameters exceed or are lower than the limit range), NG is displayed on the display 14, and the red light in the three-color light 15 flashes.

[0063] For example, reference Figures 1 to 5 The overall working process of the heating device is that the operator installs the heat shrink tube 42 on the tail section 41 of the sensor 4, and then places the sensor 4 in the limit groove 35 of the limit block 32. After adjusting the installation position of the heat shrink tube 42, the toggle clamp mechanism 33 is pressed down onto the sensor 4 to fix the sensor 4. At this time, under the action of the spring of the tensioning mechanism 34, the sensor 4 always remains in a tensioned state. The operator exits the open end 100, and the safety grating sensor 102 recognizes the signal and uploads it to the PLC.

[0064] The PLC sends the signal, and the first driving part 2 drives the fixing plate 3 to move along the second direction to the heating area (i.e., from Figure 3 The PLC receives the signal and sends a signal, and the third driving unit drives the heating carrier plate 5 to move along the first direction to the heating zone (i.e., from e to f). Figure 4 The first heating device 50 and the second heating device 52 on the heating carrier plate 5 move to the heating zone. The PLC receives the signal and sends a signal. The first heating device 50 moves toward the direction close to the heat shrink tube (i.e., along the direction along which the heat shrink tube moves) driven by the second driving part 51. Figure 4 The second heating device 52 moves in the direction close to the heat shrink tube (i.e., along the direction c shown in FIG. 1 ), driven by the fourth driving unit. Figure 4 The PLC receives the signal and sends a signal to make the first heating device 50 and the second heating device 52 blow out hot air to shrink the heat shrink tube, and the smoke filtering device 7 starts working synchronously to absorb the excess heat in the process and the exhaust gas generated when the heat shrink tube is heated.

[0065] After the process is maintained for the set time, the PLC receives the signal and sends a signal. The fifth drive unit 9 drives the industrial camera 80 and the LED light 81 to move to the heating area, takes pictures of the heat shrink tube before and after shrinkage, and compares them with the OK sample pictures in the background. During the process of photo recognition by the industrial camera 80, the first heating device 50 and the second heating device 52 return to the starting position in sequence, and the smoke filter device 7 stops working. The PLC receives the signal and sends a signal, and the fixed plate 3, the heating support plate 5, the industrial camera 80 and the LED light 81 return to the starting position in sequence. If the above comparison results are consistent, OK is displayed on the display 14, and the three-color light 15 has no response. If the above comparison results are inconsistent, it is an NG product, NG is displayed on the display 14, and the red light in the three-color light 15 flashes.

[0066] The heat shrink tube 42 is fixed by the product positioning tool 31 to prevent the heat shrink tube 42 from moving back and forth during the heating process, resulting in heating failure and affecting product quality. At the same time, the first drive unit 2, the second drive unit 51, the third drive unit, the fourth drive unit and the fifth drive unit 9 drive each component to move to the heating area to heat the heat shrink tube. After heating, each component is driven to the non-heating area to realize the automation of the entire heating process. There is no need to manually move and rotate the heat shrink tube, thereby improving production efficiency. The operator only needs to fix the heat shrink tube on the product positioning tool, which reduces the operator's work intensity and avoids the risk of burns to the operator.
