Description

Technical Field

[0001] The utility model relates to the field of resistor production equipment, in particular to a resistor guide feeding mechanism. Background Art

[0002] Thermistors, a family of sensitive components, are primarily classified into two categories based on their response to temperature changes: positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. A notable characteristic of these resistors is their extreme sensitivity to temperature changes, adjusting their resistance accordingly. Specifically, PTC thermistors increase their resistance as the temperature rises, while NTC thermistors exhibit the opposite characteristic, decreasing their resistance as the temperature rises. Both types of thermistors fall under the category of semiconductor devices.

[0003] In the production process of NTC thermistors, resistors need to be individually sorted from piles and placed on a conveyor for movement to the next processing step. However, due to the small size of thermistors, manual sorting is not only difficult, but also because the resistor pins can be too long, they may bend after removal, which can affect subsequent processing steps. Therefore, this step poses challenges to both production efficiency and product quality. Utility Model Content

[0041] Reference Figures 1-4 The basic embodiment of the first aspect of the present invention provides a resistor guide feeding mechanism, comprising:

[0042] Storage tank 100;

[0043] The mounting assembly 200 includes a mounting bracket 210 and a clamp 220, wherein the clamp 220 is used to fix the resistor;

[0044] The transfer assembly 300 includes a first power member 310 and a transfer joint 320 . The transfer joint 320 is used to attach the resistor. The first power member 310 is used to move the transfer joint 320 from the storage tank 100 to the mounting bracket 210 .

[0045] The guide assembly 400 is provided at the material storage trough 100 . The guide assembly 400 is provided with a guide groove 410 . The transfer joint 320 can pass through the guide groove 410 .

[0046] According to the embodiment of the present invention, by such a setting, at least some of the following effects can be achieved: a large amount of resistors can be stored in the storage trough 100 to prepare for subsequent processes; the first power member 310 of the transfer component 300 is used to move the resistors in the storage trough 100 to the clamping member 220 of the installation component 200. When the transfer connector 320 clamps the connector of the resistor and passes through the guide groove 410, the pins of the resistor will also pass through the guide groove 410. The guide groove 410 can straighten the pins and prevent the pins from bending. The resistors cannot be placed vertically on the installation component 200, which affects the subsequent production process.

[0047] The first power member 310 may be a cylinder, a motor, or a combination thereof, and is capable of driving the transfer joint 320 to move in the up-down, left-right, or front-back directions, which is a commonly used technical means.

[0048] In some embodiments, the transfer joint 320 includes a negative pressure power member or a clamp. The negative pressure power member secures the resistor connector to the transfer joint 320 by suctioning air, and the clamp secures the resistor connector to the transfer joint 320 by bringing at least two hooks closer together.

[0049] In some embodiments, a first embodiment of the guide assembly 400 includes at least two magnets, with the guide slot 410 disposed between the two magnets. The two magnets have identical magnetic properties. The principle of like magnets attracting and opposite magnets repelling is a fundamental law in physics that describes the interaction between magnetic materials. This principle states that if two magnets have the same magnetic poles (i.e., same polarity), they will attract each other; if they have different magnetic poles (i.e., opposite polarity), they will repel each other. This phenomenon is determined by the properties of the magnetic field. The magnetism of a magnet originates from the spin and orbital motion of its internal microscopic particles, which generate magnetic lines of force surrounding the magnets. When the like poles of two magnets approach each other, the repulsive effect of the magnetic fields causes the two magnets to repel rather than attract each other. Therefore, if an iron wire is passed between two like magnets, the repulsive effect of the magnetic fields will not attract the wire but may push it away. The repulsive effect of the two magnets on the resistor pins limits the range of motion of the resistor pins, allowing them to be straightened and more easily erected, preparing for subsequent processes.

[0050] In some embodiments, the guide slot 410 has an opening 420 that faces the mounting assembly 200. The guide assembly 400 is generally U-shaped, and the transfer connector 320 can move up and down within the slot or toward the opening 420, allowing the resistor to be installed on the mounting assembly 200 along the opening 420.

[0051] In some embodiments, in the second embodiment of the guide assembly 400, the guide groove 410 of the guide assembly 400 is circular, and the diameter of the circle is suitable for the width of the resistor. The resistor moves from bottom to top, and the guide groove 410 can straighten the pins of the resistor, so that the resistor pins can be straightened and can be better erected to prepare for subsequent processes.

[0052] In some embodiments, a guide bracket 500 is further included. The guide bracket 500 has a guide channel 510 extending along the guide slot 410 to the mounting bracket 210. The guide bracket 500 is mounted on the mounting bracket 210. After the transfer connector 320 grasps the resistor, it moves along the guide channel 510 to prevent the resistor pins from deviating from their route and affecting the installation effect.

[0053] In some embodiments, the width of the guide channel 510 gradually decreases from a direction away from the mounting bracket 210 to a direction closer to the mounting bracket 210. The gradually decreasing width serves as a guide, with the smallest width located near the clamping member 220 of the mounting bracket 210, allowing the resistor to be better mounted in the corresponding mounting position on the mounting bracket 210.

[0054] In some embodiments, the clamp 220 includes a first magnetic platform for attracting the resistor connector. The first magnetic platform is located at the upper end of the mounting bracket 210. The clamp 220 attracts the resistor connector via the first magnetic platform, allowing the resistor connector to be attached to the clamp 220, while the lead portion naturally hangs vertically downward.

[0055] In some embodiments, mounting bracket 210 is provided with a second magnetic platform 240 located at the lower end of mounting bracket 210. Second magnetic platform 240 is used to attract the resistor pins. Second magnetic platform 240 attracts the resistor pins to prevent them from shifting when mounting assembly 200 rotates, which could affect their position and hinder subsequent processing.

[0056] In some embodiments, the first magnetic platform and the second magnetic platform 240 can be electromagnets, which can control the presence or absence of magnetism by energizing, so that the resistor can be adsorbed on or detached from the mounting bracket 210; the first magnetic platform and the second magnetic platform 240 can also be provided with a power structure, which drives the first magnetic platform or the second magnetic platform 240 to approach or move away from the mounting bracket 210 through the power structure, thereby achieving a change in the strength of the magnetism, thereby achieving the function of the resistor being able to be adsorbed on or detached from the mounting bracket 210.

[0057] In some embodiments, a combing assembly 600 is further included. The combing assembly 600 includes a third power member 610 and a combing block 620. The combing block 620 is provided with a groove 621. The third power member 610 drives the combing block 620 in a top-to-bottom motion. After the resistor is clamped, multiple pins may overlap or cross before separation. During the separation operation, this may cause a second suction member to simultaneously absorb two pins, affecting the separation effect. The top-to-bottom movement of the combing block 620 combs the resistor from top to bottom, keeping multiple pins flat and facilitating subsequent separation operations.

[0058] In some embodiments, the combing block 620 is made of an elastic material, such as rubber or silicone. The combing block 620 made of an elastic material will not crush the pins.

[0059] In some embodiments, the combing assembly 600 further includes a fourth power member, which drives the third power member 610 and the combing block 620 to move in a direction toward or away from the mounting bracket 210. The fourth power member drives the combing block 620 to move in a direction toward or away from the mounting bracket 210, so that the pins can be inserted into the grooves 621 of the combing block 620.

[0060] In some embodiments, the depth of the groove 621 is less than or equal to the pin diameter. The smaller the depth of the groove 621, the more the pins can be laid out evenly after the combing block 620 is inserted into the pins. The combing block 620 moves from top to bottom, combing the resistors from top to bottom, keeping the pins even and tidy, facilitating subsequent pin separation operations.

[0061] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", "extended embodiment" may be used to describe several embodiments of the present utility model. The specific features, structures, materials or characteristics in several embodiments may be combined in accordance with the principles and purposes of the present utility model.

[0062] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as the technical effects of the present invention are achieved by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations to these embodiments within the spirit and principles disclosed in the present invention and without departing from the principles and purpose of the present invention should be included in the scope of protection disclosed in the present invention and should be deemed to fall within the scope of protection of the present invention.
