Description

Technical Field

[0001] The utility model relates to the technical field of arrester resistor production, in particular to an automatic grouping and feeding device for resistors. Background Art

[0002] Resistor grouping is a crucial step in lightning arrester manufacturing. The arrester grouping process typically begins with testing the resistors to determine their performance parameters. A printer then inkjet prints the corresponding performance parameter information onto the surface of the resistors. The resistors are then sorted and organized based on their surface performance parameters. The matching parameters for the arrester are then used to identify the resistors with the correct parameters.

[0003] Currently, the assembly process in lightning arrester manufacturing is manually performed. After reading the inkjet-coded information, the resistors are stacked together to form a column. After that, a DC high-voltage generator is used to pressurize the column to test its parameters. Furthermore, workers are required to wear cotton gloves and handle the resistors with care during the movement of the resistors. This entire process poses a high-voltage electric shock hazard, is labor-intensive, inefficient, and difficult to manage. This process no longer meets the efficient production needs of lightning arrester manufacturers. Summary of the Invention

[0004] The utility model aims at the deficiencies of the existing grouping and feeding technology and provides a resistor grouping and feeding device, which realizes efficient and orderly feeding of resistors and improves work efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a resistor group loading device, including a bracket, a positioning lifting cylinder and a positioning plate. The positioning lifting cylinder is fixedly installed on the bracket. There are two positioning lifting cylinders. The telescopic ends of the two positioning lifting cylinders are detachably connected to the two ends of the positioning plate to control the positioning plate to rise and fall. The positioning plate is provided with a number of through positioning slots for accommodating resistors. Below the positioning plate is a conveyor belt for transporting resistors, and the resistors in the positioning slots are carried by the conveyor belt.

[0006] Furthermore, the plurality of positioning slots are arranged in sequence along the length direction of the positioning plate, and the centers of the plurality of positioning slots are on a straight line.

[0007] Furthermore, the resistor assembly and loading device also includes a linear module, which is fixedly mounted on the bracket. The linear module is arranged above the positioning plate and parallel to the positioning plate. The linear module is connected to the code reader through a slider, and the code reader performs linear reciprocating motion to read the performance parameter information of the inkjet code on the resistor.

[0008] Furthermore, the code reader scans the performance parameter information corresponding to the spray coating on the surface of the resistor and collects it to the PLC for recording.

[0009] Furthermore, a semicircular operating cavity is formed on both sides of each positioning slot, and the operating cavity is communicated with the positioning slot.

[0010] Furthermore, the thickness of the positioning plate is smaller than the thickness of the resistor sheet.

[0011] Preferably, the thickness of the positioning plate is 5 mm.

[0012] Furthermore, the telescopic end of the positioning lifting cylinder is fixedly connected to a connecting plate, and the positioning plate is detachably connected to the connecting plate by bolts.

[0013] Furthermore, when the positioning plate descends to the extreme position, the upper surface of the positioning plate is flush with the upper surface of the resistor in the positioning slot; when the positioning plate rises to the extreme position, the lower surface of the positioning plate is above the upper surface of the resistor, and the positioning slot is separated from the resistor.

[0014] Furthermore, a control box is provided on one side of the bracket, and the control box is connected to the positioning lifting cylinder through a signal and controls the lifting action of the positioning lifting cylinder through an operation button.

[0015] Furthermore, the two positioning lifting cylinders are respectively located on both sides of the conveyor belt, and the conveying direction of the conveyor belt is perpendicular to the line connecting the centers of the two positioning lifting cylinders.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See attached Figure 1 , a resistor group loading device includes a bracket 1, a positioning lifting cylinder 2, a linear module 3 and a positioning plate 4, the linear module 3 and the positioning lifting cylinder 2 are fixedly installed on the bracket 1, the positioning lifting cylinder 2 is two, the telescopic ends of the two positioning lifting cylinders 2 are detachably connected to the two ends of the positioning plate 4, controlling the positioning plate 4 to lift and lower, the positioning plate 4 is provided with four through positioning slots 4.1 for accommodating the resistor, and below the positioning plate 4 is a conveyor belt for conveying the resistor (not shown in the figure), the two positioning lifting cylinders 2 are respectively located on both sides of the conveyor belt, the conveying direction of the conveyor belt is perpendicular to the line connecting the centers of the two positioning lifting cylinders, and the resistor in the positioning slot 4.1 is carried by the conveyor belt. When positioning plate 4 descends, the resistors are positioned by positioning slots 4.1. When positioning plate 4 ascends, the resistors are transported to the assembly process along the conveyor belt in their arranged positions. The linear module 3 is fixedly mounted on bracket 1, positioned above and parallel to positioning plate 4. It is connected to a barcode reader 5 via a slider 3.1. The barcode reader 5 performs linear reciprocating motion to read the performance parameters of the printed code on the resistors. A control box 6 is mounted on one side of bracket 1. This control box 6 is connected to the positioning lift cylinder 2 via a signal connection and controls the lifting and lowering of the positioning lift cylinder 2 via operating buttons.

[0021] Based on the above technical solution, a human or robot places four resistors into the four positioning slots 4.1 of the loading device at the end of the conveyor belt. After waiting for the loading confirmation button light to flash, the "Loading Confirmation" button is pressed. At this point, the two positioning lift cylinders 2 rise, allowing the conveyor belt to advance. Once in position, the positioning lift cylinders 2 automatically descend, and this process is repeated to load the material. Positioning the resistors through positioning slots 4.1 helps to arrange the resistors in an orderly manner, facilitating subsequent robot grasping of the resistors during assembly and enabling the barcode reader to scan the resistors within the fixed positioning slots during operation. This also ensures that the scanned and recorded resistor performance parameter information corresponds one-to-one with the resistors. The cylinder bases of the two positioning and lifting cylinders 2 are fixed on the bracket 1. The pistons are connected to the positioning plate 4 through the connecting plate and control the lifting of the positioning plate. The positioning and lifting cylinders 2 have a lifting function. The lifting action realized by the positioning and lifting cylinders 2 is controlled by the button switch in the control box 6 to lift. After lifting, the conveyor belt moves forward one step and the position sensor sends a signal, and then it automatically drops. The positioning and lifting cylinders 2 can also be dropped manually. The linear module 3 is driven by a belt. The belt is installed on the transmission shaft on both sides of the linear module 3. Among them, as the power input shaft, a slider 3.1 connected to the code reader 5 is fixed on the belt. When there is input, the slider 3.1 moves by driving the belt, thereby driving the code reader 5 to maintain linear reciprocating motion. The code reader 5 can use a commonly used model on the market.

[0022] In one embodiment, the four positioning slots 4.1 are arranged in sequence along the length direction of the positioning plate 4, and the centers of the four positioning slots 4.1 are on a straight line.

[0023] Based on the above technical solution, in order to facilitate the placement of the resistor and the scanning of the code reader 5, the four positioning slots 4.1 are set on the same straight line. It should be noted that four positioning slots are designed on the positioning plate of this embodiment, but the technical solution of the present utility model is not limited to this embodiment. The specific number of positioning slots is determined according to factors such as the work site, grouping efficiency and resistor specifications, and 3-6 is preferably.

[0024] In one embodiment, the code reader 5 scans the performance parameter information corresponding to the coating on the surface of the resistor and collects it to the PLC for recording. The PLC can calculate and group the resistors based on the recorded performance parameter information of each resistor.

[0025] In one embodiment, the telescopic end of the positioning lift cylinder 2 is fixedly connected to two spaced-apart connecting plates. A positioning plate 4 is inserted between the two connecting plates and detachably connected to the connecting plates via bolts. The positioning plates can be replaced to match the resistors of different specifications, achieving multiple uses for one device.

[0026] In one embodiment, the positioning plate 4 has a thickness of 5 mm, which is less than the thickness of the resistor. The positioning plate only covers the upper edge of the resistor by 5 mm, facilitating manual placement of the resistor. Semicircular operating cavities 4.11 are formed on either side of each positioning slot 4.1 and communicate with the positioning slot 4.1. These cavities facilitate manual or robotic placement of the resistor into the positioning slot 4.1. The operating cavities 4.11 do not affect the main structure of the positioning slot 4.1 and do not affect the positioning of the resistor. For positioning resistors of other specifications, the thickness of the positioning plate can be adjusted according to the size of the resistor.

[0027] In one embodiment, when the positioning plate 4 is lowered to its limit position, the upper surface of the positioning plate is flush with the upper surface of the resistor within the positioning slot 4.1. When the positioning plate 4 is lowered to its limit position, the resistor is inserted into the positioning slot 4.1. Four resistors are then stacked and slid once on the positioning plate in the direction of the positioning slots 4.1 to complete the assembly of the four resistors, eliminating the need to assemble them one by one. When the positioning plate 4 is raised to its limit position, the lower surface of the positioning plate 4 is located above the upper surface of the resistor, and the positioning slot 4.1 is separated from the resistor. The positioning slot does not restrict the resistor, and the resistor moves with the conveyor belt.
