Description

Technical Field

[0001] The utility model relates to the technical field of resistor sheet processing devices, in particular to a resistor sheet granulator. Background Technique

[0002] A resistor sheet granulator is a device specifically used for degumming and cutting alloy resistor sheets into grains. When processing small electronic products such as electronic chips and resistors, in order to obtain the final product, it is necessary to perform a degumming step on the sheet to remove the glue or adhesive on the sheet, and cut the degummed sheet into individual grains or small pieces for subsequent processing or assembly. The device includes key components such as a cylinder, an upper module, a pressing die, a lower module, spring guide posts, a product positioning block, and a punching knife. The cylinder drives the upper module to move up and down on the spring guide posts through a cylinder extension column, realizing the up and down movement of the punching knife. The punching knife is movably connected to the upper module through a fixed head and passes through the pressing die at the bottom to realize the stamping and cutting of the sheet.

[0003] For example, the Chinese authorized patent "A Degumming and Granulating Machine for Alloy Resistor Sheets" with the publication number CN213163321U includes a support table. The bottom end surface of the support table is fixedly connected with several support columns. The upper end surface of the support table is fixedly connected with a workbench. Guide rods are fixedly connected to the four corners of the workbench respectively. The upper end surface of the guide rod is fixedly provided with a cylinder support plate. A cylinder is fixedly installed on the upper end surface of the cylinder support plate. The output end of the cylinder is fixedly connected with a lifting plate. A cutting knife is fixedly installed on the bottom end surface of the lifting plate. A connecting sleeve is movably sleeved on the outer surface of the guide rod. One side of the connecting sleeve is fixedly connected with the outer side surface of the lifting plate. A punching groove is arranged on the upper end surface of the workbench. The alloy resistor sheet is placed on the workbench. The cylinder works to drive the lifting plate and the cutting knife to move downward along the guide rod. The cutting knife moves downward through the alloy resistor sheet and reaches the punching groove. In this process, the cutting and degumming work of the alloy resistor sheet is completed.

[0004] Although the above-mentioned prior art can realize the granulation work of resistor sheets, on the one hand, the feeding method is relatively simple and requires more manual intervention, which is not conducive to continuous and efficient production. On the other hand, the positioning effect is poor and the stamping misalignment is likely to occur. Therefore, it does not meet the existing requirements, and for this reason, we have proposed a resistor sheet granulator. Content of the Utility Model

[0005] The purpose of the utility model is to provide a resistor sheet granulator to solve the problems of relatively simple feeding structure of the resistor sheet granulator, which is not conducive to continuous and efficient production and poor positioning effect proposed in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a resistor sheet granulator, including a box body, the box body is composed of an upper box body and a lower box body, a workbench is fixedly installed at the middle position of the box body, a material plate moving frame is arranged on the upper end surface of the workbench, a chute for limiting the material plate is arranged on the surface of the material plate moving frame, and the material plate moving frame is fixed to the workbench through a fixing frame. An upper feeding mechanism is arranged at the front end of the material plate moving frame, and the upper feeding mechanism switches back and forth in the left-right direction to buffer the feeding process. A feeding mechanism is arranged at the front end on one side of the material plate moving frame, and the feeding mechanism transports the material plate of the upper feeding mechanism, moving from the top of the upper feeding mechanism to the material plate moving frame. A stamping mechanism is arranged at the rear end of the material plate moving frame on the workbench, and the material plate on the material plate moving frame is cut at the position of the stamping mechanism. A positioning mechanism is arranged at the rear end on one side of the material plate moving frame, which is used to move the material plate placed on the material plate moving frame by the feeding mechanism to the cutting position of the stamping mechanism.

[0007] Preferably, upper and lower feeding slide rails are installed at the front end of the upper feeding mechanism, a material bin is installed outside the upper feeding slide rail and is slidably limited thereto, and there are two material bins. A support table that is slidably fitted is installed inside the material bin, the support table is used to place stacked material plates, and the bottom of the support table is driven by an electric push rod.

[0008] Preferably, a feeding belt transmission assembly is arranged on one side of the feeding mechanism, the feeding belt transmission assembly is composed of a servo motor, two transmission wheels and a belt. A feeding slide rail is fixedly arranged at the lower end on one side of the feeding mechanism, a material plate fixing device is slidably installed outside the feeding slide rail, and one side of the material plate fixing device is connected to the belt on the feeding belt transmission assembly. Feeding hydraulic lifting assemblies are installed at the front and rear on the other side of the feeding mechanism.

[0009] Preferably, the stamping mechanism includes a stamping die, the stamping die is driven to lift by a hydraulic cylinder, a forming die adapted to it is arranged below the stamping mechanism, and a through lower leakage hole is arranged inside the forming die.

[0011] Preferably, a downwardly inclined waste material plate discharge port is arranged at the end of the material plate moving frame.

[0012] Preferably, a resistor sheet collection box is arranged at the lower end position of the box body where the resistor sheet discharge pipe is located.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model is provided with a feeding mechanism. The resistor plate is pre-stacked inside the bin. By arranging a cylinder at the bottom of the support table, the support table can be lifted, so that the resistor plate at the top is always located at the feeding position. Cooperating with the feeding mechanism, the feeding stability is improved. At the same time, the bin is slidably limited on the feeding slide rail. During the actual feeding process, after the resistor plate on one bin is moved by the plate fixing device, cooperating with the feeding slide rail, the resistor plate on the other bin is translated to the grasping position of the plate fixing device, thereby providing a buffer for the feeding process. It can not only realize continuous feeding, but also improve the feeding stability.

[0015] 2. The present utility model is provided with a feeding mechanism. The plate fixing device on the feeding mechanism can switch between the grasping position of the feeding mechanism and the discharging position of the plate moving frame. The feeding belt transmission assembly is composed of a motor, a transmission wheel and a belt. Driven by the motor, the transmission wheel rotates, and the belt is driven to move under the action of tension friction, so as to drive the plate fixing device to translate through the belt. Cooperating with the feeding slide rail can improve the stability of the plate fixing device. Under the action of the feeding hydraulic lifting assembly, the height adjustment of the plate fixing device is realized. At the same time, it uses vacuum adsorption to fix and release the contacted plate, so as to realize the switching between the grasping position and the discharging position. This mechanism has high flexibility and forms continuous automatic feeding with the feeding mechanism, effectively improving the production efficiency.

[0016] 3. The present utility model is provided with a stamping mechanism. The plate on the plate moving frame is moved above the forming die under the action of the positioning mechanism. By opening the hydraulic telescopic device of the stamping mechanism, the stamping die is driven to move towards the forming die. Under the action of pressure, the resistor plate on the surface of the plate is separated, moves down through the hole of the forming die to the resistor plate discharge pipe, and enters the collection box in the lower box through the resistor plate discharge pipe. Subsequently, under the action of the positioning mechanism, the stamped plate is discharged from the waste plate discharge port. This stamping mechanism can quickly realize the switching of the plate and the collection of the resistor plate, meeting the needs of the overall continuous production.

[0017] 4. The utility model is provided with a positioning mechanism, and the height of the positioning frame is adjusted through a positioning hydraulic lifting component. The positioning belt transmission component has the same principle as the feeding belt transmission component. The belt is used to drive the positioning frame to move to the feeding position. Subsequently, the positioning hydraulic lifting component descends to form the positioning frame to wrap the material plate. At this time, the belt drives the positioning frame to move the material plate and positions it on the material plate moving frame to the forming die position to achieve accurate positioning, improve the qualified rate of the finished resistor chip. Subsequently, the positioning frame is lifted again and moved to the feeding position. During the process of moving the material plate, the front material plate pushes the rear waste material plate, facilitating the discharge of the waste material plate from the waste material plate discharge port to achieve automatic recycling. This positioning mechanism can not only improve the cutting accuracy of the resistor chip but also has good consistency. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

A feeding mechanism 3 is arranged at the front end of the material plate moving frame 4, and the feeding mechanism 3 switches back and forth in the left-right direction to buffer the feeding process. A feeding mechanism 5 is arranged at the front end of one side of the material plate moving frame 4, and the feeding mechanism 5 transports the material plate of the feeding mechanism 3, moving from the top of the feeding mechanism 3 to the material plate moving frame 4. A stamping mechanism 6 is arranged at the rear end of the material plate moving frame 4 located on the workbench 2, and the material plate on the material plate moving frame 4 is cut at the position of the stamping mechanism 6. A positioning mechanism 7 is arranged at the rear end of one side of the material plate moving frame 4, which is used to move the material plate placed on the material plate moving frame 4 by the feeding mechanism 5 to the cutting position of the stamping mechanism 6.

[0025] During use, the material plate is at the grasping position on the feeding mechanism 3. After the feeding mechanism 5 fixes and moves the material plate at the grasping position, at the same time, the feeding mechanism 3 switches the bin position. The material plate is limited by the chute on the upper end surface of the material plate moving frame 4. Under the movement of the positioning mechanism 7, the material plate is transported to the cutting position of the stamping mechanism 6. The cut resistor sheets fall below, and at the same time, the waste material plate is discharged under the guidance of the positioning mechanism 7. This process is repeated in sequence to form continuous production.

[0026] Please refer to Figure 2 , upper and lower feeding slide rails 31 are installed at the front end of the feeding mechanism 3, a bin 32 which is slidably limited to the outside of the upper and lower feeding slide rails 31 is installed, and there are two bins 32. A support table 33 which is slidably matched is installed inside the bin 32. The support table 33 is used to place the stacked material plates, and the bottom of the support table 33 is driven by an electric push rod. By arranging a cylinder at the bottom of the support table 33, the support table 33 can be lifted, so that the resistor sheet plate at the top is always at the feeding position, cooperating with the feeding mechanism 5 to improve the feeding stability. At the same time, the bin 32 is slidably limited on the upper and lower feeding slide rails 31. During the actual feeding process, after the resistor sheet plate on one of the bins 32 is moved by the material plate fixing device 53, cooperating with the upper and lower feeding slide rails 31, the resistor sheet plate on the other bin 32 is translated to the grasping position of the material plate fixing device 53, thus providing a buffer for the feeding process.

[0027] Please refer to Figure 2 and Figure 3, on one side of the feeding mechanism 5, there is a feeding belt drive assembly 52, which consists of a servo motor, two drive wheels and a belt. At the lower end on one side of the feeding mechanism 5, a feeding slide rail 51 is fixedly arranged. Outside the feeding slide rail 51, a material plate fixing device 53 is slidably installed, and one side of the material plate fixing device 53 is connected to the belt on the feeding belt drive assembly 52. On the front and back of the other side of the feeding mechanism 5, a feeding hydraulic lifting assembly 54 is installed. The material plate fixing device 53 on the feeding mechanism 5 can switch between the grasping position of the feeding mechanism 3 and the discharging position of the material plate moving rack 4. The feeding belt drive assembly 52 consists of a motor, drive wheels and a belt. Driven by the motor, the drive wheels rotate, and under the tension friction, the belt is driven to move, thereby driving the material plate fixing device 53 to translate through the belt. Cooperating with the feeding slide rail 51 can improve the stability of the material plate fixing device 53. Under the action of the feeding hydraulic lifting assembly 54, the height adjustment of the material plate fixing device 53 is realized. At the same time, it uses vacuum adsorption to fix and release the contacted material plate to achieve the switching between the grasping position and the discharging position.

[0028] Please refer to Figure 4 , the stamping mechanism 6 includes a stamping die 61, and the stamping die 61 is driven to lift by a hydraulic cylinder. Below the stamping mechanism 6, a forming die 62 adapted to it is arranged, and a through lower leakage hole is arranged inside the forming die 62. On both sides below the forming die 62, there are resistor chip discharge pipes 63. At the lower end position of the resistor chip discharge pipes 63, a resistor chip collection box is arranged in the box body 1. At the end of the material plate moving rack 4, there is a downwardly inclined waste material plate discharge port 8. The material plate on the material plate moving rack 4 moves above the forming die 62 under the action of the positioning mechanism 7. By opening the hydraulic telescopic device of the stamping mechanism 6, the stamping die 616 is driven to move towards the forming die 62. Under the pressure, the resistor chips on the surface of the material plate are separated, move down through the holes of the forming die 62 to the resistor chip discharge pipes 63, and enter the collection box in the lower box body 1 through the resistor chip discharge pipes 63. Subsequently, under the action of the positioning mechanism 7, the stamped material plate is discharged from the waste material plate discharge port 8.

[0029] Please refer to Figure 2 and Figure 3, a positioning hydraulic lifting component 72 is provided on one side of the positioning mechanism 7. A positioning frame 73 is fixedly installed on one side of the positioning hydraulic lifting component 72, and the positioning frame 73 is connected to the positioning mechanism 7 through pulleys. Positioning hydraulic lifting components 72 are installed at the front and rear on the other side of the positioning hydraulic lifting component 72. The height of the positioning frame 73 is adjusted through the positioning hydraulic lifting component 72. The positioning belt drive component 72 has the same principle as the feeding belt drive component 52. The belt is used to drive the positioning frame 73 to move to the material discharging position. Subsequently, the positioning hydraulic lifting component 72 descends to form the positioning frame 73 to wrap the material plate. At this time, the belt drives the positioning frame 73 to move the material plate, and positions it at the position of the forming die 62 on the material plate moving frame 4 to achieve accurate positioning and improve the qualified rate of the finished resistor chips. Subsequently, the positioning frame 73 is lifted again and moved to the material discharging position. During the process of moving the material plate, the front material plate pushes the rear waste material plate, facilitating the discharge of the waste material plate from the waste material plate discharge port 8 to achieve automatic recycling.
