Description

Technical Field

[0001] This utility model belongs to the field of alloy resistor production technology, and in particular relates to a conveying device for alloy resistor production. Background Technology

[0002] Alloy resistors are resistors that use an alloy as the current-carrying medium and are often used for current sampling in circuits. They are used to provide feedback on changing currents in circuits, allowing for further control or influence of these changes. Major applications include battery protection boards, power supplies, frequency converters, lighting fixtures, and motors.

[0003] In the production process of alloy resistors, a conveying device is needed to transport the alloy resistors during production so that they can enter the next processing stage.

[0004] For example, Chinese patent CN216271481U discloses a conveying device for resistor production, including a drive wheel, a drive belt connected to the outer wall of the drive wheel, a bracket on the front of the drive belt, and a first knob at the bottom of the bracket. This device allows for adjusting the belt conveyor speed as needed, thereby improving production efficiency.

[0005] However, during the use of the above-mentioned conveying device, the resistors being conveyed can only move in a set direction, namely the direction of the extension of the conveyor belt, and cannot be reversed as needed, thus limiting the working range of the conveying device. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a conveying device for alloy resistor production, which has a simple structure and can realize 90° reversing conveying of products.

[0007] To achieve the above objectives, the present invention employs the following:

[0008] This utility model provides a conveying device for alloy resistor production, which includes a support frame. A linear drive unit is arranged on the top of the support frame along its length. The output end of the linear drive unit is connected upward to a bearing base plate. The top of the bearing base plate is fixed with the outer ring of a rotary bearing by several pins. The inner ring of the rotary bearing is connected upward to a mounting base plate. The mounting base plate and the outer ring of the rotary bearing do not contact each other. A conveyor line is arranged on the top of the mounting base plate. A horizontal drive cylinder is fixed on the surface of the bearing base plate by a bracket. A pull plate is provided on one side of the bottom of the mounting base plate. The bottom end of the pull plate extends horizontally outward to form a connecting arm. The connecting arm has a connecting post. The output end of the drive cylinder is hinged to the connecting post.

[0009] According to the present invention, a conveying device for producing alloy resistors includes two limiting seats distributed on the surface of the supporting substrate. Each limiting seat has a horizontal buffer post and a blocking plate protruding downwards on the other side of the bottom of the mounting substrate. The bottom end of the blocking plate extends horizontally outwards to form a contact plate, which is located between the two limiting seats. When the mounting substrate rotates 90° clockwise or counterclockwise, the buffer post can abut against the contact plate. Thus, by the abutting engagement of the two limiting seats with the contact plate, the device accurately determines whether the mounting substrate has completed a 90° turn or returned to its initial position, thereby improving work efficiency.

[0010] According to the present invention, a conveying device for alloy resistor production includes a linear drive unit comprising a pair of parallel side frames spaced apart on the top of a support frame. A guide rail is provided on the top of each side frame along its length, and a slider is movably mounted on the guide rail via a snap-fit ​​mechanism. The slider is connected to the bottom end of the support substrate. A horizontal cylinder is arranged along the length of the inner wall of one of the side frames, and the output end of the horizontal cylinder is connected to the bottom end of the support substrate. Thus, the horizontal cylinder drives the support substrate to move horizontally relative to the support frame, thereby achieving the lateral transfer of the conveyor line on the support substrate.

[0011] Furthermore, proximity sensors are fixed to the inner wall of the other side frame at both the front and rear via sensor brackets, and a trigger plate is positioned between the two sensor brackets at the bottom of the supporting substrate. The trigger plate engages with the proximity sensors. Thus, by utilizing the contact engagement between the trigger plate and the proximity sensors on both sides, the starting position of the supporting substrate's movement is accurately determined for material docking and transfer.

[0012] According to the present invention, a conveying device for alloy resistor production includes a support frame comprising several sets of U-shaped supports, which are connected in parallel and spaced intervals by a main beam. Thus, by using several sets of low-cost U-shaped supports combined with the main beam to form a stable support frame, the device offers good load-bearing capacity and low manufacturing cost.

[0013] According to the present invention, a conveying device for producing alloy resistors includes two upward-protruding limiting bars on each side of the top of the conveyor line. These limiting bars ensure the stability of the material during conveying and prevent accidental slippage from the sides of the conveyor line.

[0014] The beneficial effects of this utility model are as follows: through the cooperation of the conveyor line, the rotary bearing, and the drive cylinder, the conveyor line can rotate 90° to receive or feed materials, realizing flexible reversal of receiving and feeding, thereby changing the flow direction of the alloy resistor. The linear drive unit can realize the precise docking of the conveyor line with the end position of the receiving direction or the start position of the feeding direction. The receiving and feeding positions are the same, which greatly improves the work efficiency. In addition, this utility model has the characteristics of simple and compact structure and small workshop space occupation. Attached Figure Description

Detailed Implementation

[0021] To more clearly illustrate this utility model, the following description, in conjunction with preferred embodiments, further clarifies the invention. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figures 1 to 4 As shown in the figure. This utility model embodiment proposes a conveying device for alloy resistor production, including a support frame 1. A linear drive unit 2 is arranged on the top of the support frame 1 along its length direction, and the output end of the linear drive unit 2 is connected upward to a bearing substrate 3. The linear drive unit 2 realizes the forward and backward linear movement of the bearing substrate 3 relative to the support frame 1. The outer ring 41 of a rotary bearing 4 is fixed on the top of the bearing substrate 3 by several pins 31, and the inner ring 42 of the rotary bearing 4 is connected upward to a mounting substrate 5. The rotary bearing is a standard part, and its inner ring and outer ring are in a rotary rolling fit. The mounting substrate 5 does not contact the outer ring of the rotary bearing 4, ensuring that the mounting substrate 5 will not come into contact with the inner ring 42 of the rotary bearing 4 during the rotation of the mounting substrate 5. Accidental friction occurs between the outer rings 41 of the rotating bearing 4; a conveyor line 6 is set on the top of the mounting base 5. The conveyor line is a conventional conveyor line, such as a small roller conveyor line; a horizontal drive cylinder 23 is fixed on the surface of the bearing base 3 by a bracket. A pull plate 32 is set on the bottom side of the mounting base 5. The bottom end of the pull plate 32 extends outward horizontally to form a connecting arm 321. The connecting arm 321 has a connecting post 322. The output end of the drive cylinder 33 is hinged to the connecting post 322. By pulling the connecting post backward or pushing the connecting post forward by the drive cylinder 33, the connecting post, pull plate, and connecting arm are forced to drive the mounting base to rotate clockwise or counterclockwise, thus realizing the 90° reversal of the conveyor line on the mounting base.

[0024] During operation: First, the mounting base 5 is rotated by the drive cylinder 33, so that the conveying direction of the conveyor line 6 on the mounting base 5 is consistent with the conveying direction of the linear drive unit 2; then, the linear drive unit 2 controls the carrier base 3 to move the conveyor line 6 to the end position of the receiving direction, and the alloy resistor is successfully transferred to the conveyor line 6; then, the mounting base 5 is rotated 90° in the opposite direction by the drive cylinder 33, so that the conveying direction of the conveyor line 6 on the mounting base 5 is perpendicular to the conveying direction of the linear drive unit 2; finally, the linear drive unit 2 controls the carrier base 3 to move the conveyor line 6 to the starting position of the feeding direction, and the alloy resistor is transferred to the next station; the above steps are repeated.

[0025] In this embodiment, two limiting seats 34 are distributed on the surface of the supporting substrate 3. The two limiting seats 34 are arranged on the same circular trajectory and are perpendicular to each other. Each limiting seat 34 is provided with a horizontal buffer post 341. The buffer posts 341 on both limiting seats 34 are oriented inward, and a blocking plate 35 is provided protruding downward on the other side of the bottom of the mounting substrate 5. The bottom end of the blocking plate 35 extends outward horizontally to form a contact plate 351. The contact plate 351 is located between the two limiting seats 34. When the mounting substrate 5 rotates 90° clockwise or counterclockwise, the buffer post 341 can abut against the contact plate 351. In this way, the abutment and cooperation between the two limiting seats and the contact plate respectively can accurately determine whether the mounting substrate has completed a 90° turn or returned to the initial position, thereby improving work efficiency.

[0026] In this embodiment, the linear drive unit 2 includes a pair of parallel side frames 21 spaced apart on the top of the support frame 1. A guide rail 22 is provided along the length of each side frame 21, and a slider 221 is movably mounted on the guide rail 22 via a snap-fit ​​mechanism. The slider 221 is connected to the bottom end of the support substrate 3. A horizontal cylinder 23 is arranged along the length of the inner wall of one of the side frames 21, and the output end of the horizontal cylinder 23 is connected to the bottom end of the support substrate 3. Thus, the horizontal cylinder drives the support substrate to move horizontally relative to the support frame, thereby realizing the lateral transfer of the conveyor line on the support substrate.

[0027] In this configuration, proximity sensors 241 are fixed to the inner wall of the other side frame 21 via sensor brackets 24 at both the front and rear. A trigger plate 25 is positioned at the bottom of the support substrate 3 between the two sensor brackets 24, and the trigger plate 25 is used to cooperate with the proximity sensors 241. In this way, by utilizing the contact cooperation between the trigger plate and the proximity sensors on both sides, the starting position of the movement of the support substrate can be accurately determined, so as to facilitate the connection of the resistor and the transmission of the resistor.

[0028] In this embodiment, the support frame 1 includes several sets of I-shaped brackets 11, which are connected in parallel and spaced intervals by main beams 12. Thus, by using several sets of low-cost I-shaped brackets in combination with the main beams to form a stable support frame, the support provides good load-bearing capacity and low manufacturing cost.

[0029] In this embodiment, two limiting bars 61 protrude upwards from each of the top two sides of the conveyor line 6. In this way, the limiting bars on both sides ensure the stability of the resistor during the conveyor line's connection and delivery of the resistor, and prevent the resistor from accidentally slipping off the side of the conveyor line.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
