[0002] During the production of ceramic substrates, the process typically involves working on a ceramic substrate to create a large number of regularly arranged ceramic substrates. The ceramic substrate is then broken into strips, and finally, these strips are broken into individual electrodes. After being broken into strips, the ceramic substrate needs to be loaded into a fixture to facilitate subsequent processes.

[0007] Preferably, a guide groove is provided on the surface opposite to the lifting groove, and the sliders fixed on both sides of the lifting plate surface can extend into the guide groove. A guide groove is provided on the surface of the lifting groove on one side of the guide groove.

[0008] Preferably, a second movable hole is provided inward on the surface of the lifting plate on one side of the base, and a first movable hole is provided on both sides of the surface of the lifting plate through the second movable hole. One end of the first movable rod is placed in the second movable hole, and a guide block extends from the surface of the first movable rod into the first movable hole, with one end of the guide block extending into the second guide groove.

[0009] Preferably, the reciprocating screw is provided with a rectangular rod arranged in parallel, with its two ends extending to the top and bottom surfaces of the lifting groove, respectively. A second pulley is fitted onto the outer circumference of the rectangular rod, and the center of the second pulley is fixedly connected to the outer circumference of the rectangular rod.

[0010] Preferably, the lifting plate has a vibration groove inside, and a rotating shaft column is fixed on both sides of the bottom surface of the vibration groove. A rotating shaft passes through one side of the outer surface of the rotating shaft column, and the rotating shaft is supported and fixed through the rotating shaft column.

[0011] Preferably, the upper surface of the lifting plate is provided with a rotating hole, and a rotating wheel that can rotate is provided at the coaxial center of the rotating hole. A crown gear is fixed on the outer circumference of the rotating wheel, and the crown gear is meshed with a gear fixed at one end of the rotating shaft. An inclined wheel is fixed on the outer circumference of the rotating shaft.

[0012] Preferably, a pulley is fixed below the outer peripheral surface of the reciprocating lead screw, and a belt is sleeved between the pulley and the second pulley.

[0013] Preferably, one end of the moving rod has a moving groove extending inward, while the positioning rod is slidably disposed in the moving groove. Guide grooves are respectively provided on the bottom and top surfaces of the moving groove. Meanwhile, sliders are fixed on the bottom and top surfaces of the positioning rod, with one end of sliders extending into the interior of guide grooves.

[0014] Preferably, the surface of the vibration groove is provided with a guide groove four, and a swing rod is slidably arranged in the guide groove four. The other end of the swing rod extends to a telescopic hole opened at one end of the positioning rod, and the swing rod is above the inclined wheel. Two limiting posts extend from the bottom of the swing rod toward the inclined wheel, and the two limiting posts clamp the inclined wheel.

[0015] The resistance storage hopper positioning device and positioning method of the present invention have the following advantages:

[0016] 1. The positioning device and method for the resistance storage hopper, when the storage hopper moves to the positioning groove, the cylinder rod of cylinder one can position the storage hopper, and at the same time the motor rotates, and then the reciprocating screw provided at the output end of the motor can rotate together. After the reciprocating screw rotates, the lifting plate can move upward. Since one end of the guide block extends to the guide groove two, one end of the positioning rod can then abut against the surface of the storage hopper, thereby further positioning it.

[0017] 2. In the resistor storage hopper positioning device and method, when the reciprocating screw is driven to rotate by the motor, pulley one drives pulley two to rotate together via the belt. Subsequently, the rectangular rod can rotate. After the rectangular rod rotates, the rotating wheel sleeved on its outer rear can rotate together. Then, the crown gear on the outer circumference of the rotating wheel drives the meshing gear below, and then the inclined wheel on the outer circumference of the rotating shaft rotates, thereby generating vibration. Then, under the rotation of the reciprocating screw, the vibration is transmitted to the storage hopper through the positioning rod, so that the resistor can be unloaded. Furthermore, under the rotation of the reciprocating screw, the positioning rod will move up and down on the surface of the storage hopper, thereby further improving the resistance unloading efficiency.

[0018] 3. The positioning device and method for the resistance storage hopper, when the storage hopper needs to vibrate to prevent blockage during material feeding, the inclined wheel rotates and generates vibration. At the same time, since the two limit posts are located on both sides of the inclined wheel, when the inclined wheel rotates, the swing rod can continuously move laterally along the four directions of the guide groove. This allows the positioning rod that vibrates up and down to resist the up and down vibration while also moving left and right to vibrate, further improving the material feeding and blockage prevention.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1-6As shown, the resistor storage hopper positioning device of the present invention includes a frame 1, and a vibrating feeding plate 11 is fixed on one side of the upper surface of the frame 1. The resistor material can be placed in the vibrating feeding plate 11. A track 13 is connected to the feeding point of the vibrating feeding plate 11, and the material can be vibrated and conveyed through the track 13. At the end of the track 13, a conveying component 25 is also connected. The conveying component 25 is composed of a conveying shaft and is driven by a motor.

[0036] A base 2 is fixed below the opposite side of the conveying assembly 25. The bottom surface of the base 2 is fixed to the upper surface of the frame 1. A positioning groove 21 is provided on the upper surface of the base 2. A storage bin 3 is filled inside the positioning groove 21. A jig clamp 15 is provided at the entrance of the positioning groove 21. The storage bins 3 are placed in sequence at the opening of the jig clamp 15.

[0037] A support base 151 is located below the jig clamp 15 to support the jig clamp 15. A pushing component 14 is also provided on one side of the jig clamp 15. This pushing component 14 consists of a cylinder and a clamp connected to the front end of the cylinder rod. As the cylinder operates, the clamp at the front end of the cylinder rod pushes the storage bin 3, which then moves from the jig clamp 15 to the positioning slot 21. Simultaneously, a cylinder 12 is also provided inside the frame 1. One end of the cylinder rod of this cylinder 12 extends to the bottom surface of the positioning slot 21. Therefore, when the storage bin 3 moves onto the positioning slot 21, the cylinder rod end on the bottom surface of the positioning slot 21 abuts against the bottom surface of the storage bin 3, thereby positioning and fixing it.

[0038] like Figures 4-7 As shown, a back plate 22 is fixed to one side of the outer surface of the base 2. A lifting groove 24 is formed through the surface of the back plate 22. A motor plate 241 is fixed to the surface of the back plate 22 away from the base 2. The surface of the motor plate 241 is flush with the bottom surface of the lifting groove 24. A motor 4 is also fixed to the bottom surface of the motor plate 241. A reciprocating screw 41 is provided through the motor plate 241 from the output end of the motor 4 upwards. Therefore, when the motor 4 is running, the reciprocating screw 41 can be driven. A top plate 23 is fixed to the upper part of one side of the outer surface of the back plate 22. The top plate 23 is opposite to the base 2, and the conveying assembly 25 is also provided on one side of the top plate 23. A pressing assembly 16 is also provided on one side of the back plate 22. The pressing end of the pressing assembly 16 faces upwards from the storage bin 3.

[0039] A lifting plate 5 is positioned opposite to the bottom surface of the lifting groove 24. A reciprocating hole 51 is formed through the surface of the lifting plate 5 for the reciprocating screw 41 to pass through. An insert is provided on the inner ring wall of the reciprocating hole 51, with one end extending into a path formed on the surface of the reciprocating screw 41. This path consists of two threaded grooves with the same pitch but opposite directions, connected at both ends by a transition curve. Therefore, when the reciprocating screw 41 rotates, it drives the lifting plate 5 to move up and down. A guide groove 242 is formed on the opposite surface of the lifting groove 24. Slider blocks 54, fixed on both sides of the surface of the lifting plate 5, extend into the guide groove 242. By moving the sliders 54 along the inside of the guide groove 242, the lifting plate 5 can be limited in its vertical movement.

[0040] A second guide groove 243 is provided on the surface of the lifting groove 24 located on one side of the first guide groove 242. The middle section of the second guide groove 243 is inclined and its two ends are connected to the vertical groove opening. A second moving hole 531 is provided on the surface of the lifting plate 5 facing the base 2. Moving holes 53 are provided on both sides of the surface of the lifting plate 5 and extend into the second moving hole 531. A movable moving rod 6 is provided inside the second moving hole 531. A guide block 61 extends from the surface of the first moving rod 6 into the first moving hole 53, and one end of the guide block 61 extends into the second guide groove 243. A positioning rod 62 is also provided at the end of the first moving rod 6. Therefore, when the storage bin 3 moves to the positioning groove 21, the cylinder rod of cylinder 12 can position the storage bin 3. At the same time, the motor 4 rotates, and the reciprocating screw 41 at the output end of the motor 4 rotates as well. After the reciprocating screw 41 rotates, the lifting plate 5 can move upward. Since one end of the guide block 61 extends to the guide groove 243, one end of the positioning rod 62 can then abut against the surface of the storage bin 3, thereby further positioning it. A ball bearing 622 is also provided at the end of the positioning rod 62.

[0041] like Figures 6-10 As shown, a rectangular rod 246 is arranged parallel to the reciprocating lead screw 41. The two ends of the rectangular rod 246 extend to the top and bottom surfaces of the lifting groove 24, respectively. A pulley 247 is fitted onto the outer circumference of the rectangular rod 246, and the center of the pulley 247 is fixedly connected to the outer circumference of the rectangular rod 246. A vibration groove 55 is formed inside the lifting plate 5, and rotating shaft columns 551 are fixed on both sides of the bottom surface of the vibration groove 55. One end of a rotatable rotating shaft 7 passes through the rotating shaft column 551, thereby supporting and fixing the rotating shaft 7.

[0042] A rotating hole 52 is provided through the upper surface of the lifting plate 5. A rotating wheel 521 is provided at the coaxial center of the rotating hole 52. A crown gear 522 is fixed on the outer circumference of the rotating wheel 521. The crown gear 522 is meshed with a gear 71 fixed at one end of the rotating shaft 7. An inclined wheel 72 is fixed on the outer circumference of the rotating shaft 7. A pulley 42 is fixed below the outer circumference of the reciprocating screw 41. A belt 43 is sleeved between the pulley 42 and the second pulley 247. When the reciprocating screw 41 is driven to rotate by the motor 4, the first pulley 42 drives the second pulley 247 to rotate together through the belt 43. Then the rectangular rod 246 can rotate. After the rectangular rod 246 rotates, the rotating wheel 521 sleeved on its outer rear end can rotate together. Then the crown gear 522 on the outer circumference of the rotating wheel 521 drives the gear 71 meshing below. Then the inclined wheel 72 on the outer circumference of the rotating shaft 7 rotates, thereby generating vibration. Then, under the rotation of the reciprocating screw 41, the vibration is transmitted to the storage bin 3 through the positioning rod 62, so that the resistor can be fed. Under the rotation of the reciprocating screw 41, the positioning rod 62 will move up and down on the surface of the storage bin 3, thereby further improving the resistance feeding jamming.

[0043] like Figures 7-13 As shown, a moving groove 63 extends inward from one end of the moving rod 6, while a positioning rod 62 is slidably disposed within the moving groove 63. The length of the positioning rod 62 is less than that of the moving groove 63, allowing the positioning rod 62 to move within the moving groove 63. Guide grooves 631 are respectively provided on the bottom and top surfaces of the moving groove 63. Slider 623 is fixed on the bottom and top surfaces of the positioning rod 62, with one end of the slider 623 extending into the guide groove 631, allowing the positioning rod 62 to slide along the length of the moving groove 63. A guide groove 56 is provided on the surface of the vibration groove 55, and a swing rod 8 is slidably disposed within the guide groove 56. The other end of the swing rod 8 extends into the telescopic hole 621 at one end of the positioning rod 62, and the swing rod 8 is positioned above the inclined wheel 72. Two limiting posts 81 extend from the bottom of the swing rod 8 towards the inclined wheel 72, clamping the inclined wheel 72. Therefore, when the storage bin 3 needs to vibrate to prevent blockage during material feeding, the inclined wheel 72 rotates and generates vibration. At the same time, since the two limit posts 81 are located on both sides of the inclined wheel 72, when the inclined wheel 72 rotates, the swing rod 8 can continuously move laterally along the guide groove 56. This allows the positioning rod 62, which vibrates up and down, to resist the up and down vibration while also vibrating left and right, further improving the material feeding and blockage prevention.

[0044] Working principle of the resistance storage hopper positioning device and positioning method: When the storage hopper 3 moves to the positioning groove 21, the cylinder rod of cylinder 12 can position the storage hopper 3. At the same time, the motor 4 rotates, and the reciprocating screw 41 at the output end of the motor 4 can rotate together. After the reciprocating screw 41 rotates, the lifting plate 5 can move upward. Since one end of the guide block 61 extends to the guide groove 243, one end of the positioning rod 62 can abut against the surface of the storage hopper 3, thereby further positioning it.

[0045] When the reciprocating screw 41 is driven to rotate by the motor 4, the first pulley 42 drives the second pulley 247 to rotate together through the belt 43. Then the rectangular rod 246 can rotate. After the rectangular rod 246 rotates, the rotating wheel 521 sleeved on its outer rear can rotate together. Then the crown gear 522 on the outer circumference of the rotating wheel 521 drives the gear 71 meshing below. Then the inclined wheel 72 on the outer circumference of the rotating shaft 7 rotates, thereby generating vibration. Then, under the rotation of the reciprocating screw 41, the vibration is transmitted to the storage bin 3 through the positioning rod 62, so that the resistor can be fed. Under the rotation of the reciprocating screw 41, the positioning rod 62 will move up and down on the surface of the storage bin 3, thereby further improving the resistance feeding jamming.

[0046] When the storage bin 3 needs to vibrate to prevent blockage during material feeding, the inclined wheel 72 rotates and vibrates. At the same time, since the two limit posts 81 are located on both sides of the inclined wheel 72, when the inclined wheel 72 rotates, the swing rod 8 can move horizontally along the guide groove 46 direction continuously. This allows the positioning rod 62, which vibrates up and down, to resist the up and down vibration while also vibrating left and right, further improving the material feeding and blockage prevention.

[0047] It should be noted that the specific models and specifications of the vibrating feeder 11, cylinder 12 and motor 4 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0048] The power supply and operating principle of the vibrating feeder 11, cylinder 12 and motor 4 are clear to those skilled in the art and will not be described in detail here.

[0049] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
