Description

Technical Field

[0001] The utility model relates to the technical field of end-burning furnaces, in particular to a belt speed testing device and a mesh belt type end-burning furnace. Background Art

[0002] At present, the world is at the intersection of two major innovations: the energy revolution and the computer revolution. Driven by fields such as 5G communications, smart phones and new energy vehicles, the development of the electronic information industry is thriving and has become an important pillar of the economic market.

[0003] Among them, multilayer ceramic capacitors (MLCC), as the passive electronic components with the largest market share, have become one of the key products that require breakthroughs in key technologies for technological innovation. MLCC has the advantages of high capacitance, small size, low cost, and high reliability. It is widely used in automotive electronics, electrical control, power grid frequency modulation, instrumentation, aerospace, and other fields, and is known as the "rice of the electronics industry."

[0004] In the existing technology, the main process flow of MLCC is: batching → casting → printing → lamination → lamination → cutting → debinding → sintering → chamfering → end sealing → end burning → end treatment → electrical performance testing → qualified, packaging and warehousing.

[0005] Moreover, when the MLCC products undergo the end-burning process, the MLCC products need to pass through a mesh belt type end-burning furnace about 15 meters long for the end-burning treatment.

[0006] In addition, the main influencing factors of the mesh belt burning furnace on MLCC products are: temperature, belt speed (mesh belt speed), and atmosphere.

[0007] In summary, in order to improve the quality of MLCC products, the belt speed measurement of the mesh belt type end-burning furnace is very important. The operation mode of the mesh belt in the end-burning furnace is: the mesh belt drive motor drives the active guide wheel through a belt or chain, the active guide wheel and the driven guide wheel squeeze the mesh belt, and the active guide wheel drives the mesh belt to operate through friction.

[0008] The belt speed test logic adopted by the traditional belt speed testing device of the mesh belt type firing end furnace (for example, an external computer that can perform theoretical calculations) is: converting the rotation speed of the mesh belt drive motor to the belt speed, and monitoring the rotation speed of the mesh belt drive motor by using the traditional belt speed testing device, thereby achieving the purpose of testing the belt speed of the mesh belt.

[0009] However, the traditional belt speed test device still has the following defects:

[0010] (1) When the mesh belt is abnormally stuck or there is slippage between the mesh belt and the active guide wheel, the mesh belt drive motor is still rotating at the original speed. At this time, the belt speed converted by the speed of the mesh belt drive motor has a huge deviation from the actual belt speed. Therefore, the traditional belt speed test device cannot monitor the belt speed abnormality;

[0011] (2) Due to the large length of the burning end furnace, when the mesh belt is relaxed, there may be a deviation between the belt speed at the furnace head and the belt speed at the active guide wheel, which may cause the belt speed calculated by the speed of the mesh belt drive motor to deviate from the actual belt speed of the MLCC entering the furnace.

[0063] Figure 1 A schematic structural diagram of a belt speed testing device provided in an embodiment of the utility model. Figure 2 This is a schematic structural diagram of a firing end furnace provided in an embodiment of the utility model. Figure 3 The present invention is a schematic diagram of an exploded view of a belt speed testing device provided in an embodiment of the present invention.

[0064] See also Figure 1-Figure 3 The belt speed testing device 100 includes: a mounting bracket 1, a speed collecting component 2, a movable connecting component 3, a spring 4 and a speed measuring component 5.

[0065] The mounting bracket 1 is composed of a bracket body 11 and a sliding portion 12 extending along a first direction 101 ; the sliding portion 12 is disposed on the bracket body 11 .

[0066] In addition, the speed collection component 2 includes: a pair of rollers 21 with rotating shafts 22; a preset gap 201 is provided between the pair of rollers 21, so that the mesh belt can pass through the preset gap 201 and be clamped; a pair of rotating shafts 22 are fixed on the sliding part 12 through a movable connection component 3, so that the rotating shafts 22 can move on the sliding part 12 along the first direction 101.

[0067] In an embodiment of the present application, the roller 21 can be made of a material with a large friction coefficient such as rubber, so that the surface where the roller 21 contacts the mesh belt 2001 has a large friction force, which can effectively prevent the roller 21 and the mesh belt 2001 from slipping; and the rotating shaft 22 and the bearing cooperate with each other, so that the rotation resistance of the rotating shaft 22 is small; in summary, by adding the mutual cooperation of the bearing and the rotating shaft and using rubber and other materials with a large friction coefficient to make the roller 21, the belt speed on the mesh belt 2001 can be accurately converted into the rotation speed on the roller 21, thereby improving the testing accuracy of the belt speed testing device 100.

[0068] Specifically, the rotating shaft 22 and the drum 21 rotate synchronously; that is, when the belt speed on the mesh belt 2001 is accurately converted into the rotation speed on the drum 21, the rotation speed on the rotating shaft 22 is equal to the rotation speed on the drum 21.

[0069] It can be understood that the spring 4 is sleeved on the sliding portion 12 and is located between the movable connecting component 3 and the bracket body 11; the spring 4 can provide an elastic force for driving a pair of rotating shafts 22 to have a tendency to close to each other.

[0070] In the embodiment of the present application, four springs 4 are installed on the vertical first sliding rod 121 and the second sliding rod 122 of the mounting bracket 1, respectively controlling the two active sliders 31 and the two driven sliders 32 to move toward the middle; wherein, the function of the spring 4 is to squeeze the two rollers 21 toward the middle and close together, so that the friction force when the rollers 21 contact with the mesh belt 2001 is greater, and it is easier to be driven to rotate by the mesh belt 2001.

[0071] It should be noted that the rotation speed measuring component 5 is sleeved on one of the rotating shafts 22 of the rotation speed collecting component 2 , connected to at least a part of the movable connecting component 3 , and is used to measure the rotation speed information of the rotation speed collecting component 2 .

[0072] In some embodiments, Figure 1 and Figure 3 As shown, the support body 11 includes a first support 111 and a pair of second supports 112 .

[0073] Specifically, the pair of second pillars 112 extend from two ends of the first pillar 111 that are away from each other and in a direction away from the first pillar 111 .

[0074] In the implementation of the present application, the first support 111 and the pair of second support 112 enclose a receiving space; the sliding portion 12 is disposed in the receiving space.

[0075] The sliding portion 12 includes a first sliding rod 121 and a second sliding rod 122 which are parallel to each other.

[0076] In addition, two ends of the first sliding rod 121 that are away from each other in the first direction 101 are connected to a pair of second pillars 112 ; and two ends of the second sliding rod 122 that are away from each other in the first direction 101 are connected to a pair of second pillars 112 .

[0077] In some embodiments, in combination Figure 1 and Figure 3 It can be seen that the movable connection component 3 includes: a pair of active sliders 31 and a pair of driven sliders 32 .

[0078] It can be understood that the active slider 31 is provided with a first through hole 311 and a second through hole 312 ; the driven slider 32 is provided with a third through hole 321 and a fourth through hole 322 .

[0079] It should be noted that a pair of active sliders 31 are sleeved on the first sliding rod 121 through the first through hole 311; a pair of driven sliders 32 are sleeved on the second sliding rod 122 through the third through hole 321; bearings are provided in the second through hole 312 and the fourth through hole 322, and the rotating shaft 22 cooperates with the bearings so that the rotating shaft 22 is assembled to the movable connecting component 3 through the bearings.

[0080] In some embodiments, according to Figure 1 and Figure 3 It can be known that the belt speed testing device 100 further includes: a driving component 6 .

[0081] Specifically, one part of the driving component 6 is hinged to the first support column 111 through the rotating connecting component 7, and the other part is fixed to the first sliding rod 121 through the sliding connecting component 8; the sliding connecting component 8 is connected to the active sliding block 31.

[0082] The rotating connection component 7 may be a rivet or a bolt that cooperates with a nut.

[0083] In addition, a through hole 1111 is formed on the first pillar 111 of the bracket body 11 , and the rivet mentioned above can pass through the through hole 1111 to hinge the pair of pressing parts 61 to the first pillar 111 .

[0084] In the embodiment of the present application, in response to the application of an external force 1001, the driving component 6 can drive a pair of rotating shafts 22 to move along the first direction 101 through the mutual connection between the sliding connection component 8 and the active slider 31, so that the preset gap 201 changes with the movement of the rotating shaft 22.

[0085] In some implementations, see Figure 1 and Figure 3 The belt speed testing device 100 also includes: an information processing component 9.

[0086] The information processing component 9 is disposed on one of the second pillars 112 of the bracket body 11 .

[0087] In addition, the information processing component 9 is connected to the rotation speed measuring component 5 for communication and is used to process the rotation speed information.

[0088] In some embodiments, please refer to Figure 1 and Figure 3 The information processing component 9 includes: a controller 91 and a display 92.

[0089] It should be noted that the rotation speed measuring component 5 includes: a Hall sensor 51 and a cable 52; the Hall sensor 51 is used to sense the rotation speed on the rotating shaft 22 to form rotation speed information; the rotation speed information is transmitted to the controller 91 through the cable 52 to form belt speed information.

[0090] Specifically, the display 92 and the controller 91 can convert the rotation speed of the rotating shaft 22 sensed by the Hall sensor 51 into the actual belt speed and display it; at the same time, the unit, mode and other information can be set.

[0091] The Hall sensor 51 can sense the rotation speed of the rotating shaft 22 . The Hall sensor 51 is fixed on one of the driven sliders 32 and can move synchronously with the rotating shaft 22 .

[0092] It can be understood that a communication connection is formed between the controller 91 and the display 92; the display 92 is used to receive and present the belt speed information.

[0093] In some embodiments, Figure 1 and Figure 3 It can be seen that the sliding connection component 8 includes: a pair of connecting sliders 81.

[0094] The pair of connecting sliders 81 are connected to the pair of active sliders 31 ; the connecting sliders 81 are provided with fifth through holes 811 and connecting bosses 812 .

[0095] In addition, when the connecting slider 81 is connected to the active slider 31 , the fifth through hole 811 and the first through hole 311 are coaxially arranged.

[0096] In some embodiments, Figure 1 and Figure 3 As shown, the driving component 6 includes a driving portion 62 and a pair of pressing portions 61 .

[0097] Specifically, a pair of pressing parts 61 are hinged to the first support 111 through a rotating connecting member 7;

[0098] In the embodiment of the present application, the driving portion 62 includes a pair of driving rods 621 and a pair of connecting heads 622 ; the connecting head 622 is disposed at one end of the driving rod 621 ; and a mounting hole 6211 is disposed at the other end of the driving rod 621 .

[0099] It is understandable that a mounting channel 6212 extending from the mounting hole 6211 toward the connecting head 622 is provided inside the driving rod 621 ; at least a portion of the pressing portion 61 is inserted into the mounting channel 6212 to connect the pressing portion 61 and the driving portion 62 .

[0100] In the embodiment of the present application, the driving rod 621 is not only hollow inside (that is, a mounting channel 6212 is provided inside the driving rod 621), but also has a retractable function; wherein the connecting member 612 can be inserted into the mounting channel 6212 to form a fitting connection.

[0101] It should be noted that the connecting head 622 is provided with a connecting through hole 6221 adapted to the connecting boss 812 ; the connecting head 622 is hinged to the connecting slider 81 through the mutual cooperation between the connecting boss 812 and the connecting through hole 6221 .

[0102] In some embodiments, in combination Figure 1 and Figure 3 It can be seen that the pressing portion 61 includes a base 611 and a connecting member 612 .

[0103] The base 611 has a first end and a second end which are opposite to each other; a hinge hole 6111 is provided at the first end of the base 611; and a preset angle 6110 is provided between the base 611 and the connecting member 612.

[0104] In addition, the second end of the base 611 is configured to apply an external force 1001 that overcomes the elastic force, so that the pair of bases 611 tend to close together and the pair of connectors 612 tend to separate from each other.

[0105] In an embodiment of the present application, a user can squeeze a pair of bases 611 (that is, a pair of bases 611 are equivalent to two handles that can be held by the user, so that the user can apply an external force 1001) against each other, thereby driving a pair of retractable driving rods 621 to move up and down respectively, and at the same time driving a pair of connecting sliders 81 to move up and down respectively, and at the same time driving a pair of active sliders 31 to move up and down respectively, thereby forcing the rollers 21 made of rubber material to separate from each other, and the preset gap 201 increases, so that the mesh belt 2001 can pass through the above-mentioned preset gap 201; after loosening the pair of bases 611, the pair of rollers 21 can clamp the above-mentioned mesh belt 2001.

[0106] Combination Figure 1-Figure 3 It can be seen that the end-burning furnace 200 includes: a drive system 2000, a mesh belt 2001 and a furnace body 2002; the drive system 2000 is arranged on the furnace body 2002, and the mesh belt 2001 and the drive system 2000 cooperate with each other so that the mesh belt 2001 has a preset belt speed.

[0107] Among them, at least one of the above-mentioned belt speed testing devices 100 can be arranged on the mesh belt 2001; the mesh belt 2001 is clamped by a pair of rollers 21 of the speed collection component 2 of the belt speed testing device 100, which can drive the rollers 21 to rotate synchronously, so that the preset belt speed of the mesh belt 2001 is converted into the speed of the rotating shaft 22 of the speed collection component 2.

[0108] It should be noted that the furnace body 2002 has a pair of furnace heads 2004 at two ends facing away from each other.

[0109] In an embodiment of the present application, the drive system 2000 may include: a mesh belt drive motor 2003, a driving guide wheel 2005, a pair of driven guide wheels 2006 located on both sides of the driving guide wheel 2005, a conveyor belt or chain 2009 respectively connected to the driving guide wheel 2005 and the mesh belt drive motor 2003, a plurality of tensioning wheels 2007 located on a pair of furnace heads 2004, and a pair of furnace head driven wheels 2008.

[0110] Specifically, the belt speed testing logic adopted by the belt speed testing device 100 provided in the present application is: first, the roller 21 in the belt speed testing device 100 is used to clamp the mesh belt 2001 in the burning end furnace 200, so that the belt speed on the mesh belt 2001 can be converted into the rotation speed on the roller 21, and sensed by the Hall sensor 51 installed on one of the rotating shafts 22 to form the rotation speed information; then, the rotation speed information is transmitted to the controller 91, and after being processed by the controller 91, the corresponding belt speed information is obtained, and the belt speed information is transmitted to the display 92; finally, the belt speed information is displayed on the display 92, so that the belt speed testing device 100 has a visualization function.

[0111] It should be noted that in order to improve the belt speed test accuracy, multiple belt speed test devices 100 can be used to simultaneously measure the belt speed of multiple locations of the mesh belt 2001 to avoid inaccurate belt speed measurement due to loosening of the mesh belt 2001 .

[0112] In summary, the logic adopted by the belt speed testing device 100 provided in the present application can avoid inaccurate belt speed testing and the inability to monitor belt speed abnormalities caused by abnormal conditions such as the mesh belt 2001 getting stuck or slipping.

[0113] Combination Figure 1-Figure 3 , the use process of the handheld direct belt speed measurement of the belt speed test device 100 is described in detail: first, the user holds the bracket body 11; then, the user presses the pair of bases 611, thereby applying the external force 1001 to the second ends of the pair of bases 611, forcing the pair of bases 611 to close together; at this time, the pair of connecting members 612 separate from each other, thereby forcing the connecting slider 81 to drive the active slider 31 to move away from each other along the first direction 101, so that the pair of rotating shafts 22 separate from each other along the first direction 101, so that the preset gap 201 between the pair of rollers 21 becomes larger; Next, the mesh belt 2001 is passed through the preset gap 201, and at the same time, the user releases a pair of bases 611; at this time, the spring 4 provides elastic force to make a pair of rotating shafts 22 and a pair of rollers 21 close to each other along the first direction 101, so that the roller 21 can clamp the mesh belt 2001; finally, the mesh belt 2001 with a preset belt speed drives the roller 21 to rotate, and drives the rotating shaft 22 to rotate synchronously, and through the induction of the Hall sensor 51 and processing through the controller 91 and the display 92, the belt speed of the mesh belt 2001 can be visually displayed on the display 92.

[0114] Combination Figure 1-Figure 3, the process of fixing the belt speed testing device 100 on the furnace head 2004 of the burning end furnace 200 to measure the belt speed is described in detail: first, the user presses the pair of bases 611, so that the external force 1001 can be applied to the second end of the pair of bases 611, forcing the pair of bases 611 to close together; at this time, the pair of connecting members 612 separate from each other, thereby forcing the connecting slider 81 to drive the active slider 31 to move away from each other along the first direction 101, so that the pair of rotating shafts 22 separate from each other along the first direction 101, so that the preset gap 201 between the pair of rollers 21 becomes larger; then, the mesh belt 2001 passes through the preset gap 201, and at the same time, the user loosens the pair of bases 611, and the spring 4 provides elastic force to make the pair of rotating shafts 22 and the pair of rollers 21 are closed together along the first direction 101, so that the roller 21 can clamp the mesh belt 2001; then, the bracket body 11 of the belt speed testing device 100 is fixed at a suitable position of the furnace head 2004; then, the controller 91 forms a communication connection with the display 92 and the main control computer of the burning end furnace respectively; then, the mesh belt 2001 with a preset belt speed drives the roller 21 to rotate, and drives the rotating shaft 22 to rotate synchronously, and forms a belt speed signal through the induction of the Hall sensor 51 and processing by the controller 91; finally, the belt speed signal is transmitted to the display 92 and the main control computer of the burning end furnace, so that the belt speed of the mesh belt 2001 can be visually displayed on the display 92, and the belt speed of the mesh belt 2001 can be controlled by the main control computer of the burning end furnace.

[0115] In the embodiments of the present application, Figure 2 As shown, the operation process of the mesh belt 2001 in the burning end furnace 200 is described in detail: first, the mesh belt driving motor 2003 is rotated to drive the conveyor belt or chain 2009 to drive the driving guide wheel 2005 to rotate; then, there is a driven guide wheel 2006 on both sides of the driving guide wheel 2005, and the mesh belt 2001 can pass through the gap between the two driven guide wheels 2006 and the driving guide wheel 2005 to surround the driving guide wheel 2005 for most of a circle, so that the two driven guide wheels 2006 and the driving guide wheel 2005 are squeezed against each other, thereby increasing the friction between the mesh belt 2001 and the driving guide wheel 2005; finally, when the driving guide wheel 2005 rotates, the mesh belt 2001 can be driven to operate.

[0116] In summary, the belt speed test device and the end-burning furnace provided by the embodiment of the utility model adopt a pair of rollers to clamp the mesh belt so that the belt speed of the mesh belt is converted into the rotation speed of the rollers, and the addition of springs can make the mesh belt in an elastic clamping state, so that the belt speed test device is not affected by the slippage of the mesh belt, the test position, and the shape of the mesh belt. In addition, the belt speed test device also has the advantages of simple structure, low cost, and small footprint. Therefore, the belt speed test device provided by the embodiment of the utility model has certain novelty compared with the traditional belt speed test device.
