Description

Technical Field

[0001] This invention relates to the field of resistor production equipment technology, and in particular to an integrated device for resistor detection and dispensing. Background Technology

[0002] Resistors, as the most basic electronic components, are widely used in various electronic devices. In the automated production process of resistors, resistance testing and dispensing are two crucial steps. Resistance testing typically involves measuring the resistance value to reject products with initially unacceptable values, ensuring that the products meet specifications. Dispensing involves applying a specific adhesive (such as insulating adhesive, moisture-proof adhesive, or mounting adhesive) to the resistor's substrate or terminals to achieve insulation, fixation, or protection. In current resistor production models, these two steps are generally completed on two independent, separate machines. That is, resistors are first tested and sorted on the testing equipment. After testing, batches of resistors are manually or transported in transfer boxes to the dispensing equipment for adhesive application.

[0003] However, after testing, the resistors need to be removed from the tray or fixture of the testing equipment and then placed into the fixture of the dispensing equipment. Separate testing and dispensing equipment mean two independent loading / unloading systems, control systems, and operators are required, resulting in large equipment investment, a large floor space, and high costs. The transfer of resistors between processes not only increases material handling time and labor costs but also easily causes production interruptions and waiting times, making it difficult to form a continuous and smooth automated production line and restricting the output capacity per unit time. Summary of the Invention

[0004] The main objective of this invention is to provide an integrated resistance detection and dispensing device, which aims to solve the technical problem that in the current resistance generation process, dispensing and detection are two independent systems, resulting in many steps and high production costs.

[0005] To achieve the above objectives, the present invention proposes an integrated resistance detection and dispensing device, comprising:

[0006] A conveyor rail is used to convey a resistor to be tested. The conveyor rail is provided with a conveyor guide groove. The resistor to be tested is disposed in the conveyor guide groove and has an insertion part extending out of the conveyor guide groove. The resistor to be tested moves along the conveyor guide groove, and the conveyor guide groove is also used to restrict the resistor to be tested from leaving the conveyor guide groove from perpendicular to the conveying direction. In the conveying direction, the conveyor rail is provided with a detection position and a feeding position in sequence. A testing mechanism is located on one side of the conveyor rail. The testing mechanism includes a plug. At the testing position, the plug is used to connect to the connector of the resistor to be tested for testing. A dispensing device includes a dispensing machine, a support rail, and a material transfer mechanism. The support rail has a receiving position, a dispensing position, and a unloading position. The material transfer mechanism drives a resistor from the receiving position to the dispensing position, and further transfers it to the unloading position. The dispensing machine is positioned corresponding to the dispensing position and dispenses adhesive to the resistor after testing. The feeding mechanism is connected to the conveyor rail and the transferring mechanism respectively, and is used to transfer the resistor to be tested from the loading position to the receiving position.

[0007] In one embodiment, the material transfer mechanism includes a first material transfer drive, a second material transfer drive, a first material transfer seat, and a second material transfer seat. The first material transfer drive is connected to the first material transfer seat and drives the first material transfer seat to move, thereby moving the resistor from the receiving position to the dispensing position or from the dispensing position to the unloading position. The first material transfer drive and the first material transfer seat are both disposed on the second material transfer seat. The second material transfer drive is connected to the second material transfer seat and drives the second material transfer seat to move, causing the first material transfer seat to move closer to or further away from the resistor. The driving directions of the first material transfer seat and the second material transfer seat are perpendicular.

[0008] In one embodiment, the first transfer seat is provided with two transfer plates, which are spaced apart. The distance between the two transfer plates is adapted to the distance between the receiving position and the dispensing position, as well as the distance between the dispensing position and the unloading position. The transfer plate is provided with a pick-and-place part for picking up and placing resistors.

[0009] In one embodiment, the pick-and-place portion is configured as a notch that extends to the edge of the transfer plate and is adapted to the resistor, serving to accommodate the resistor and move the resistor.

[0010] In one embodiment, a first slide rail is slidably connected to the bottom of the first transfer seat, and the first slide rail is disposed on the second transfer seat; The integrated resistance detection and dispensing equipment also includes a worktable, which is provided with a second slide rail. The second material transfer drive unit drives the second material transfer seat to slide along the second slide rail.

[0011] In one embodiment, the material misalignment mechanism includes a material misalignment drive, a material misalignment block, and a material misalignment guide seat. The material misalignment block has a first position corresponding to the conveying rail and a second position corresponding to the receiving position. The material misalignment guide seat is provided with a material misalignment guide groove. The material misalignment drive is connected to one end of the material misalignment block and drives the material misalignment block to slide along the material misalignment guide groove, causing the material misalignment block to reciprocate between the first position and the second position. The end of the material misalignment block away from the material misalignment drive also has a receiving opening, which is adapted to the resistance.

[0012] In one embodiment, the detection mechanism further includes a support base and a detection drive component. The detection drive component is disposed on the support base, and the plug is disposed on the detection drive component. The detection drive component drives the plug to move so that the plug is inserted into the resistor to be tested.

[0013] In one embodiment, the integrated resistance detection and dispensing equipment further includes a feeding mechanism and a feeding conveyor line. The feeding mechanism includes a transverse module, a feeding drive, and feeding grippers. The feeding drive is disposed on the transverse module, and the feeding grippers are disposed on the feeding drive. The transverse module drives the feeding drive and the feeding grippers to reciprocate between the feeding position and the feeding conveyor line. The feeding grippers are used to grip resistors.

[0014] In one embodiment, the conveyor rail is provided with an intermittent conveyor line, and the end of the conveyor rail opposite to the loading position is provided with a material receiving position. The intermittent conveyor line sequentially conveys the resistor to be tested located at the material receiving position to the detection position and the loading position along the conveyor rail.

[0015] In one embodiment, the integrated resistance detection and dispensing equipment further includes a vibratory feeder, a pushing component, and a feeding conveyor line. The feeding conveyor line is located between the vibratory feeder and the conveyor rail. The pushing component pushes the resistor to be tested to move, thereby transferring the resistor to be tested from the feeding conveyor line to the conveyor rail.

[0016] This invention integrates resistance testing and dispensing processes—originally requiring two separate devices—into a single unit by employing an integrated conveyor rail, testing mechanism, dispensing device, and misalignment mechanism. This not only reduces equipment procurement and maintenance costs but also compresses the workshop space required for the production line, alleviating equipment investment and floor space constraints, thus facilitating cost control. By sequentially setting testing and loading positions along the conveyor rail in the conveying direction, and utilizing the misalignment mechanism to directly transfer the tested resistor from the loading position to the receiving position of the dispensing device, a seamless connection from resistance testing to dispensing is achieved. Compared to existing technologies that require manual handling or intermediate material boxes for inter-process transfer, this eliminates material handling waiting time, forming a continuous and smooth automated production line, effectively increasing production capacity per unit time. A conveyor guide groove is provided on the conveyor rail, serving two purposes: firstly, to transport the resistor to be tested, and secondly, to limit the resistor's detachment perpendicular to the conveying direction, ensuring the stability of the resistor's position during plug insertion and removal testing. After testing, the resistor is directly transferred to the support rail of the dispensing device via the misalignment mechanism, requiring no manual operation throughout the process and improving the accuracy of the dispensing position.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0024] In existing technologies, after resistors are tested, they need to be removed from the tray or fixture of the testing equipment and then placed into the fixture of the dispensing equipment. Separate testing and dispensing equipment mean two independent loading / unloading systems, control systems, and operators are required, resulting in large equipment investment, large floor space, and high costs. The transfer of resistors between processes not only increases material handling time and labor costs but also easily causes production interruptions and waiting times, making it difficult to form a continuous and smooth automated production line and restricting the output capacity per unit time.

[0025] This invention proposes an integrated device for resistance detection and dispensing.

[0026] Please see Figures 1 to 6As shown, in one embodiment of the present invention, the integrated resistance detection and dispensing device includes: a conveyor rail 100, a detection mechanism 200, a dispensing device 300, and a feeding mechanism 500. The conveyor rail 100 is used to convey the resistor to be tested. The conveyor rail 100 is provided with a conveying guide groove 110. The resistor to be tested is disposed within the conveying guide groove 110 and has an insertion portion extending out of the conveying guide groove 110. The resistor to be tested moves along the conveying guide groove 110, and the conveying guide groove 110 also restricts the resistor to be tested from detaching from the conveying guide groove 110 perpendicular to the conveying direction. In the conveying direction, the conveyor rail 100 is sequentially provided with a detection position 120 and a feeding position 130. The detection mechanism 200 is disposed on the conveyor rail 100. On one side, the testing mechanism 200 includes a plug 210, which is used to insert into the connector of the resistor to be tested at the testing position 120 for testing; the dispensing device 300 includes a dispensing machine 310, a support rail 320 and a material transfer mechanism 400. The support rail 320 is provided with a receiving position 321, a dispensing position 322 and a discharging position 323. The material transfer mechanism 400 drives the resistor from the receiving position 321 to the dispensing position 322 and further transfers it to the discharging position 323. The dispensing machine 310 is set corresponding to the dispensing position 322 and dispenses glue to the resistor after testing; the material transfer mechanism 500 is connected to the conveying rail 100 and the material transfer mechanism 400 respectively, and is used to transfer the resistor to be tested from the loading position 130 to the receiving position 321.

[0027] The conveyor rail 100 is used to convey the resistor to be tested. In specific implementations, the conveyor rail 100 is provided with a conveyor guide groove 110 along its length. The resistor to be tested is accommodated and confined within the conveyor guide groove 110. The resistor to be tested has a body and a plug-in portion (e.g., metal leads or electrodes of the resistor) extending from the body. This plug-in portion extends outside the conveyor guide groove 110 to facilitate subsequent electrical connection with the plug 210 of the detection mechanism 200. The cross-sectional shape of the conveyor guide groove 110 matches the shape of the resistor to be tested, thereby preventing the resistor to be tested from detaching from the conveyor guide groove 110 perpendicular to the conveying direction, ensuring its positional stability and directional consistency during the conveying process. The resistor to be tested moves along the conveyor guide groove 110, for example, by a drive method (not shown in the figure) such as a push rod, a dial wheel, or a conveyor belt, and is conveyed forward in a step-by-step or continuous manner. Along the conveying direction, the conveyor rail 100 is sequentially provided with a detection position 120 and a loading position 130. Detection position 120 is the position for resistance value testing, and loading position 130 is the position where the tested resistors are waiting to be transferred to the next process.

[0028] The detection mechanism 200 is located on one side of the conveyor rail 100, corresponding to the detection position 120. The detection mechanism 200 includes a movable plug 210 (e.g., a probe or insertion clamp) and a resistance measurement module (e.g., an LCR bridge or a digital multimeter, not shown) electrically connected to the plug 210. At the detection position 120, after the resistor to be measured is conveyed into position, the plug 210 extends and forms a tight electrical contact with the insertion part of the resistor to be measured, thereby measuring the resistance value. After the detection is completed, the plug 210 resets, and the resistor is allowed to continue moving forward to the loading position 130.

[0029] The dispensing device 300 is used to dispense adhesive onto qualified resistors. In practice, the dispensing device 300 includes a support rail 320, a dispensing machine 310, and a transfer mechanism 400. The support rail 320 has a receiving position 321, a dispensing position 322, and a discharging position 323 along its length. The receiving position 321 is adjacent to the loading position 130 of the conveyor rail 100 and is used to receive resistors transferred from the loading position 130. The dispensing position 322 corresponds to the nozzle of the dispensing machine 310 and is the dispensing location. The discharging position 323 is where the dispensed resistors are removed or collected. The transfer mechanism 400 is located on one side or above the support rail 320 and is used to clamp or attract resistors, driving them to move from the receiving position 321 to the dispensing position 322 on the support rail 320, and then further transfer them to the discharging position 323 after dispensing. The material handling mechanism 400 may be a component including grippers and a drive slide, or other automated handling device capable of linear or curved reciprocating motion.

[0030] The material transfer mechanism 500 is connected between the conveyor rail 100 and the dispensing device 300. Specifically, the material transfer mechanism 500 is located between the loading position 130 of the conveyor rail 100 and the receiving position 321 of the support rail 320. The material transfer mechanism 500 is used to transfer the resistor (i.e., the resistor after testing) located at the loading position 130 to the receiving position 321. The material transfer mechanism 500 can take various forms, such as a simple pushing mechanism, including a push plate or lever perpendicular to the conveying direction. When the resistor reaches the loading position 130, the push plate moves laterally, pushing the resistor from the conveying guide groove 110 into the receiving position 321 of the support rail 320. Alternatively, the material transfer mechanism 500 can also be a robotic arm capable of picking up and placing resistors.

[0031] The integrated resistance detection and dispensing device provided in this embodiment allows resistors to be tested to move forward sequentially along the conveying guide groove 110 of the conveying rail 100. When a resistor reaches the detection position 120, the plug 210 of the detection mechanism 200 activates, inserting into the resistor's connector to detect its resistance. After detection, the plug 210 retracts, and the resistor continues to move forward to the loading position 130. Simultaneously, the next resistor to be tested reaches the detection position 120. The misalignment mechanism 500 activates, transferring the resistor from the loading position 130 to the receiving position 321 of the support rail 320. Subsequently, the transfer mechanism 400 pushes the resistor, moving it along the support rail 320 to the dispensing position 322. Upon reaching the dispensing position 322, the dispensing machine 310 starts, applying adhesive to the designated location on the resistor. After dispensing, the transfer mechanism 400 activates again, moving the resistor to the unloading position 323, awaiting subsequent collection or entry into the next process. Resistors are conveyed sequentially, thereby achieving continuous parallel operation of detection and dispensing.

[0032] This invention integrates the resistance value detection and dispensing processes, which originally required two separate devices, into a single unit by employing an integrated conveyor rail 100, detection mechanism 200, dispensing device 300, and misalignment mechanism 500. This not only reduces equipment procurement and maintenance costs but also compresses the workshop space required for the production line, alleviating equipment investment and floor space requirements, thus facilitating cost control. By sequentially setting detection positions 120 and loading positions 130 along the conveying direction on the conveyor rail 100, and using the misalignment mechanism 500 to directly transfer the detected resistor from the loading position 130 to the receiving position 321 of the dispensing device 300, a seamless connection from resistance detection to dispensing is achieved. Compared to the existing technology that requires manual or intermediate material boxes for inter-process transfer, this eliminates material handling waiting time, forming a continuous and smooth automated production line, effectively improving the production capacity per unit time. A conveying guide groove 110 is provided on the conveying rail 100. This groove serves two purposes: firstly, it conveys the resistor to be tested; secondly, it limits the resistor's detachment in the direction perpendicular to the conveying direction, ensuring the stability of the resistor's position during the plug-in / plug-out testing process. After testing, the resistor is directly transferred to the support rail 320 of the dispensing device 300 via the material transfer mechanism 500. The entire process requires no manual operation, improving the accuracy of the dispensing position 322.

[0033] Please see Figure 2As shown, in one embodiment, the transfer mechanism 400 includes a first transfer drive 410, a second transfer drive 420, a first transfer seat 430, and a second transfer seat 440. The first transfer drive 410 is connected to the first transfer seat 430 and drives the first transfer seat 430 to move, so as to move the resistor from the receiving position 321 to the dispensing position 322 or from the dispensing position 322 to the unloading position 323. The first transfer drive 410 and the first transfer seat 430 are both disposed on the second transfer seat 440. The second transfer drive 420 is connected to the second transfer seat 440 and drives the second transfer seat 440 to move, so that the first transfer seat 430 moves closer to or further away from the resistor. The driving directions of the first transfer seat 430 and the second transfer seat 440 are perpendicular.

[0034] The second transfer seat 440 serves as a mounting base, supporting some components of the transfer mechanism 400. The second transfer drive 420 is connected to the second transfer seat 440 and drives the second transfer seat 440 to move along a first direction. This first direction is configured to be along the direction of resistor delivery on the support rail 320, close to or away from the resistor located on the support rail 320, for example, a horizontal direction perpendicular to the length of the support rail 320 (i.e., transverse). Driven by the second transfer drive 420, the initial positioning of the resistor during clamping or releasing can be achieved. The first transfer drive 410 is connected to the first transfer seat 430 and drives the first transfer seat 430 to move along a second direction, perpendicular to the first direction. In this embodiment, the second direction is configured to be parallel to the length of the support rail 320 (i.e., longitudinal) to facilitate the transfer of the resistor between the receiving position 321, the dispensing position 322, and the unloading position 323. The first transfer drive 410 and the first material seat are both mounted on the second transfer seat 440, meaning that the first transfer seat 430 can slide relative to the second transfer seat 440 in a second direction. The first transfer seat 430 is provided with a clamping part (e.g., a claw or a groove structure) for clamping resistors, which can be pushed to move synchronously, and the clamping part moves synchronously with the first transfer seat 430.

[0035] When resistor transfer is required, firstly, the second transfer drive 420 actuates, driving the second transfer seat 440 to move along the first direction, so that the clamping part on the first transfer seat 430 approaches and accurately reaches the position of the resistor (e.g., receiving position 321), and the clamping part clamps the resistor. Then, the first transfer drive 410 activates, driving the first transfer seat 430 to move along the second direction (longitudinal), thereby moving the clamping part and the clamped resistor from the receiving position 321 to the dispensing position 322. After reaching the dispensing position 322, the second transfer drive 420 slightly moves or remains stationary to adjust the dispensing height or position of the resistor, ensuring dispensing accuracy. After dispensing is complete, the first transfer drive 410 again drives the first transfer seat 430, moving the resistor from the dispensing position 322 to the unloading position 323. After reaching the unloading position 323, the second transfer drive 420 actuates, moving the clamping part away from the resistor, releasing the clamping part, and completing the unloading process. Subsequently, the material transfer mechanism 400 resets, awaiting the next operation.

[0036] By setting the first transfer drive 410 and the second transfer drive 420 with their driving directions perpendicular to each other, the transfer mechanism 400 of this embodiment achieves motion decoupling in the X and Y directions, enabling the transfer mechanism 400 to accurately complete actions in two dimensions: using the second transfer drive 420 to realize the approach and exit actions during clamping and releasing, and using the first transfer drive 410 to realize the transfer action between workstations. This not only improves the flexibility and positioning accuracy of material transfer, but also makes the control logic clearer, facilitating high-speed and stable automated operation.

[0037] Furthermore, the first transfer base 430 is provided with two transfer plates 450, which are spaced apart. The distance between the two transfer plates 450 is adapted to the distance between the receiving position 321 and the dispensing position 322, as well as the distance between the dispensing position 322 and the unloading position 323. The transfer plate 450 is provided with a pick-and-place part for picking up and placing resistors.

[0038] In this embodiment, the first transfer base 430 includes two transfer plates 450, namely a first transfer plate 450 and a second transfer plate 450. The two transfer plates 450 are spaced apart and are both connected to the first transfer drive member 410, so that they can move synchronously along the second direction under the drive of the first transfer drive member 410. The spacing between the two transfer plates 450 is adapted to the spacing between the stations on the support rail 320. Specifically, the spacing is configured to be equal to the distance between the receiving position 321 and the dispensing position 322, and also equal to the distance between the dispensing position 322 and the unloading position 323. In other words, the spacing between the two transfer plates 450 is consistent with the standard spacing between adjacent stations on the support rail 320.

[0039] Each transfer plate 450 is equipped with a pick-and-place section for picking up and placing resistors. This section can be a miniature pneumatic gripper, an elastic mechanical gripper, or a vacuum nozzle for adsorbing resistors. Initially, the pick-and-place section of the first transfer plate 450 is aligned with the receiving position 321 of the support rail 320, and the pick-and-place section of the second transfer plate 450 is aligned with the dispensing position 322. Once the resistor is in place at the receiving position 321, the second transfer drive 420 drives the second transfer seat 440 to move along the first direction, causing the pick-and-place sections of both transfer plates 450 to simultaneously approach and contact the resistors at their respective positions. Subsequently, the pick-and-place section of the first transfer plate 450 picks up the resistor to be dispensed at the receiving position 321; simultaneously, the pick-and-place section of the second transfer plate 450 picks up the resistor that has already been dispensed at the dispensing position 322 (if there is a resistor at the dispensing position 322). The first transfer drive 410 is activated, driving the first transfer base 430 (i.e., the two transfer plates 450) to move a distance equal to one station spacing along the second direction. Since the spacing between the two transfer plates 450 is equal to the station spacing, after the movement, the first transfer plate 450 and the resistor to be dispensed carried by it reach the dispensing position 322; the second transfer plate 450 and the dispensing completed resistor carried by it reach the unloading position 323. The second transfer drive 420 then drives the second transfer base 440 to move along the first direction, causing the pick-up and place parts of the two transfer plates 450 to disengage from the corresponding resistors, so that the first transfer plate 450 places the resistor to be dispensed at the dispensing position 322, waiting for the dispensing machine 310 to dispense it; the second transfer plate 450 places the dispensing completed resistor at the unloading position 323, waiting for subsequent collection. The transfer mechanism 400 resets to the initial state, preparing for the next round of transfer operations.

[0040] In one reciprocating motion, the material transfer mechanism 400 can simultaneously complete two operations: picking up material from the receiving position 321 and sending it to the dispensing position 322, and picking up material from the dispensing position 322 and sending it to the unloading position 323. This combines the actions that originally required two motion cycles into one cycle, improving material transfer efficiency and reducing the idle stroke of the material transfer mechanism 400, thereby increasing the overall production cycle and capacity of the equipment.

[0041] In the specific implementation process, the pick-and-place section is configured with a notch 451, which extends to the edge of the transfer plate 450. The notch 451 is adapted to the resistor and is used to accommodate the resistor and push the resistor to move. The notch 451 extends inward from the edge of the transfer plate 450, forming an open structure. The shape of the notch 451 is adapted to the shape of the resistor, and the size of the notch 451 is slightly larger than the size of the resistor, so that the resistor can be accommodated in the notch 451. When the transfer plate 450 moves, the sidewall of the notch 451 can contact the resistor, thereby pushing the resistor to move. When transfer is required, the second transfer drive 420 drives the second transfer seat 440 to move in the first direction (lateral), so that the notches 451 of the two transfer plates 450 approach and fit into the resistors at their respective workstations.

[0042] In one embodiment, a first slide rail 460 is slidably connected to the bottom of the first transfer seat 430, and the first slide rail 460 is disposed on the second transfer seat 440; the resistance detection and dispensing integrated device also includes a worktable, the worktable is provided with a second slide rail 470, and the second transfer drive 420 drives the second transfer seat 440 to slide along the second slide rail 470.

[0043] In this embodiment, the integrated resistance detection and dispensing device also includes a worktable, which serves as the mounting base for the entire device, supporting and mounting various functional modules such as the conveyor rail 100, detection mechanism 200, dispensing device 300, and material feeding mechanism 500. In specific implementation, a second slide rail 470 is provided on the worktable, extending along a first direction (i.e., the driving direction of the second material transfer drive 420, i.e., the direction closer to or further from the resistor). The second material transfer drive 420 is connected to a second material transfer seat 440 and drives the second material transfer seat 440 to slide along the second slide rail 470. Specifically, a second slider (not shown in the figure) adapted to the second slide rail 470 is provided at the bottom of the second material transfer seat 440, and the second slider slides in cooperation with the second slide rail 470. Guided by the second slide rail 470, the second material transfer seat 440 can reciprocate smoothly and accurately along the first direction.

[0044] A first slide rail 460 is provided on the second transfer seat 440, extending along a second direction (i.e., the driving direction of the first transfer drive 410, which is the station transfer direction parallel to the length direction of the support rail 320). A first slider (not shown in the figure) adapted to the first slide rail 460 is provided at the bottom of the first transfer seat 430, and the first slider slides in cooperation with the first slide rail 460. The first transfer drive 410 is connected to the first transfer seat 430 and drives the first transfer seat 430 to slide along the first slide rail 460.

[0045] Please see Figures 2 to 5As shown, in one embodiment, the material misalignment mechanism 500 includes a material misalignment drive 510, a material misalignment block 520, and a material misalignment guide seat 530. The material misalignment block 520 has a first position corresponding to the conveying rail 100 and a second position corresponding to the receiving position 321. The material misalignment guide seat 530 is provided with a material misalignment guide groove 531. The material misalignment drive 510 is connected to one end of the material misalignment block 520 and drives the material misalignment block 520 to slide along the material misalignment guide groove 531, and causes the material misalignment block 520 to reciprocate between the first position and the second position. The end of the material misalignment block 520 away from the material misalignment drive 510 also has a receiving opening 521, which is adapted to the resistance.

[0046] In the specific implementation process, the material guide seat 530 is fixedly installed on the workbench, located between the loading position 130 of the conveyor rail 100 and the receiving position 321 of the support rail 320 of the dispensing device 300. The material guide seat 530 is provided with a material guide groove 531 extending along a first direction, which is perpendicular to the conveying direction of the conveyor rail 100 and the support rail 320. The material block 520 is slidably accommodated in the material guide groove 531. One end of the material block 520 is connected to the connecting end of the material drive component 510 (e.g., a cylinder, electric cylinder, or linear motor). The material drive component 510 is used to drive the material block 520 to slide along the material guide groove 531. Under the drive of the material drive component 510, the material block 520 can reciprocate between the first position and the second position. The first position corresponds to the loading position 130 of the conveyor rail 100, meaning that when the misaligned block 520 moves to the first position, it can contact the resistor located at the loading position 130. The second position corresponds to the receiving position 321 of the support rail 320, meaning that when the misaligned block 520 moves to the second position, it can push the resistor to the receiving position 321. A receiving port 521 is provided at the end of the misaligned block 520 away from the misaligned drive member 510. The shape of the receiving port 521 is adapted to the shape of the resistor, and the receiving port 521 is used to accommodate and push the resistor during the pushing process.

[0047] When the inspected resistor (qualified product) is conveyed to the loading position 130 of the conveyor rail 100, the resistor stops moving forward. At this time, the misalignment block 520 is in the first position, and the resistor is accommodated in the receiving port 521. The misalignment drive unit 510 drives the misalignment block 520 to move along the misalignment guide groove 531 to the second position. During the movement, the misalignment block 520 pushes the resistor through the side wall of the receiving port 521, causing it to detach from the loading position 130 of the conveyor rail 100 and move smoothly in a direction perpendicular to the conveying direction. When the misalignment block 520 moves to the second position, the resistor is precisely pushed onto the receiving position 321 of the support rail 320. The misalignment block 520 resets and moves back to the first position, and the resistor disengages from the receiving port 521, or the receiving port 521 retracts and resets as the misalignment block 520, leaving the resistor in the receiving position 321. By setting the misalignment guide seat 530 and its internal misalignment guide groove 531, this embodiment provides guidance for the reciprocating motion of the misalignment block 520, ensuring the straightness of the resistor transfer path and the consistency of its position. The design of the receiving port 521 serves to limit and protect, preventing the resistor from tipping over or shifting during high-speed pushing.

[0048] In one embodiment, the detection mechanism 200 further includes a support base and a detection drive unit. The detection drive unit is disposed on the support base, and the plug 210 is disposed on the detection drive unit. The detection drive unit drives the plug 210 to move so that the plug 210 is inserted into the resistor to be measured.

[0049] In practical implementation, the support base is fixedly installed on the workbench, located on one side of the conveyor rail 100, corresponding to the detection position 120. The support base provides a stable mounting foundation for other components of the detection mechanism 200. The detection drive component is mounted on the support base and can be a drive element capable of providing linear reciprocating motion, such as a cylinder, electric cylinder, linear motor, or electromagnet. The detection drive component has a movable drive end, and a plug 210 is located at the drive end of the detection drive component and connected to it. The plug 210 is used to form electrical contact with the insertion part of the resistor to be measured. The plug 210 may include one or more probes, springs, or insertion terminals, the specific form of which is adapted to the structure of the insertion part of the resistor to be measured. The plug 210 is also electrically connected to a resistance measurement module (not shown in the figure, such as an LCR bridge or a digital multimeter). The detection drive component is used to drive the plug 210 to move, specifically towards or away from the insertion part of the resistor to be measured, so that the plug 210 can be inserted into the resistor to be measured for detection, or retract after detection.

[0050] Please see Figure 1 , Figure 2 and Figure 5As shown, in one embodiment, the integrated resistance detection and dispensing equipment further includes a feeding mechanism 600 and a feeding conveyor line. The feeding mechanism 600 includes a transverse module 610, a feeding drive 620, and a feeding gripper 630. The feeding drive 620 is disposed on the transverse module 610, and the feeding gripper 630 is disposed on the feeding drive 620. The transverse module 610 drives the feeding drive 620 and the feeding gripper 630 to reciprocate between the feeding position 323 and the feeding conveyor line. The feeding gripper 630 is used to grip resistors.

[0051] In practice, a feeding conveyor line is located on one side of the equipment to transport the dispensing resistors to the next process (e.g., curing oven, packaging machine, etc.) or to a collection container. The feeding conveyor line can be a belt conveyor, chain conveyor, or other form of continuous or stepping conveyor. A feeding mechanism 600 is located between the feeding position 323 of the dispensing device 300 and the feeding conveyor line to pick up the dispensing resistors at the feeding position 323 and transfer them to the feeding conveyor line.

[0052] The transverse module 610 is mounted on the worktable and extends along a third direction. This third direction is configured to point from the unloading position 323 towards the unloading conveyor line (or vice versa), and is typically a horizontal direction parallel to the length of the support rail 320. The transverse module 610 can be a linear module, such as a motor-driven lead screw slide module, synchronous belt module, or linear motor module, to provide precise linear reciprocating motion. The unloading drive 620 is disposed on the moving slide of the transverse module 610, and thus can reciprocate along the third direction under the drive of the transverse module 610. The unloading drive 620 can be a linear drive element such as a cylinder or electric cylinder, and its driving direction is preferably vertical, used to realize the lifting action of the unloading gripper 630, so as to pick up material from the unloading position 323 and unload material onto the unloading conveyor line. The unloading gripper 630 is disposed at the drive end of the unloading drive 620 and connected to the unloading drive 620. The unloading jaw 630 is used to clamp resistors. It can be a pneumatic jaw, an electric jaw, or a mechanical elastic jaw, etc. The shape of its clamping part is adapted to the shape of the resistor to ensure stable clamping and no damage to the resistor.

[0053] By setting up the unloading mechanism 600 and the unloading conveyor line, this embodiment realizes the automatic unloading and output of resistors after dispensing, without manual intervention, reducing labor costs and avoiding the risk of contamination or damage that may be caused by manual operation. As the resistors are conveyed by the unloading conveyor line, the unloading drive unit 620 can also neatly arrange them on the unloading conveyor line or in the corresponding fixture, avoiding collisions between adjacent resistors.

[0054] In one embodiment, the conveyor rail 100 is provided with an intermittent conveyor line (not shown in the figure), and the end of the conveyor rail 100 opposite to the loading position 130 is provided with a material receiving position. The intermittent conveyor line transports the resistor to be tested located at the material receiving position to the detection position 120 and the loading position 130 along the conveyor rail 100 in sequence.

[0055] A material receiving position is provided at one end of the conveyor rail 100 away from the loading position 130 (i.e., the starting end of the conveyor rail 100). The material receiving position is the initial position where the resistor to be tested enters the conveyor rail 100, and is used to receive the resistor to be tested from upstream equipment (such as a vibratory feeder, hopper, or loading robot). The intermittent conveyor line is used to sequentially transport the resistor to be tested located at the material receiving position along the conveyor rail 100 to the detection position 120 and the loading position 130. The intermittent conveyor line adopts an intermittent (or step-by-step) conveying method, that is, at regular time intervals, the resistor is pushed forward one station distance, so that the resistor can stay at the detection position 120 and the loading position 130 for a sufficient time to complete the corresponding detection and mis-material transfer actions.

[0056] In a preferred embodiment, the intermittent conveyor line includes a conveying drive and a feeding device. The conveying drive (e.g., a stepper motor, a cylinder with a ratchet mechanism, etc.) is located on one side of the conveyor rail 100. The feeding device is connected to the conveying drive and reciprocates along the conveying direction under the drive of the conveying drive. The feeding device is equipped with a pawl (not shown in the figure), which contacts the resistor to be measured. Each time it moves, the pawl pushes a resistor forward one position (e.g., from the detection position 120 to the loading position 130, while simultaneously pushing the next resistor from the waiting position to the detection position 120, and pushing the new resistor from the incoming position into the waiting position). After the conveying drive completes one push, the feeding device resets, and the pawl bypasses the resistor during the reset process (e.g., by lifting or retracting), preparing for the next push.

[0057] As another preferred embodiment, the intermittent conveyor line can also employ a stepper conveyor belt or chain conveyor mechanism, with equally spaced stops or grooves on the conveyor belt or chain, each stop or groove accommodating one resistor. The conveyor belt or chain is driven by a stepper motor, advancing one stop distance at a time, thereby achieving intermittent, equidistant conveying of the resistors.

[0058] Initially, the resistor to be tested is placed at the incoming material position on the conveyor rail 100 via the upstream feeding mechanism. The intermittent conveyor line starts, and the conveyor drive unit drives the feeding mechanism to push the resistor to be tested forward one station distance along the conveyor guide groove 110. After one or more pushes, the first resistor is conveyed to the detection position 120. The resistor stops at the detection position 120, where the detection mechanism 200 detects its resistance value. After detection, the intermittent conveyor line starts again, conveying the resistor from the detection position 120 to the upper material position 130, while simultaneously pushing the next resistor to be tested into the detection position 120 from the rear. The intermittent conveyor line sequentially conveys resistors from the incoming material position to the detection position 120 and the upper material position 130 according to a set rhythm, enabling the entire detection and mis-material handling process to be carried out in an orderly and automatic manner without manual intervention, thus improving the automation level and production efficiency of the equipment.

[0059] refer to Figure 6 As shown, in one specific embodiment, the integrated resistance detection and dispensing equipment further includes a vibratory feeder 700, a pushing component, and a feeding conveyor line 710. The feeding conveyor line 710 is located between the vibratory feeder 700 and the conveyor rail 100. The pushing component pushes the resistor to be tested to move, and causes the resistor to be tested to be transferred from the feeding conveyor line 710 to the conveyor rail 100.

[0060] In practical implementation, a vibratory feeder 700 is located at one end of the equipment and is used to store and organize the resistors to be tested. The vibratory feeder 700 includes a vibratory plate and a linear vibratory feeder. The vibratory plate contains a large number of bulk resistors to be tested. Through the vibration of the vibratory plate, the resistors are oriented and rise along the spiral track, and are finally conveyed to the linear vibratory feeder in a uniform posture (e.g., pins facing outward or upward). The linear vibratory feeder further conveys the resistors forward until they reach the beginning of the feeding conveyor line 710.

[0061] A feeding conveyor line 710 is positioned between the vibrating feeder 700 and the conveyor rail 100. Specifically, one end of the feeding conveyor line 710 is connected to the output end of the linear vibrating feeder, and the other end is adjacent to the material receiving position of the conveyor rail 100. The feeding conveyor line 710 is used to receive the resistors to be measured from the vibrating feeder 700 and convey them towards the conveyor rail 100. The feeding conveyor line 710 can be a belt conveyor, a chain conveyor, or a linear vibrating conveyor trough, etc., and its conveying speed is matched with the discharge speed of the vibrating feeder 700 and the cycle time of subsequent processes.

[0062] A pusher assembly is located at the junction of the feeding conveyor line 710 and the conveyor rail 100. It is used to move the resistor to be measured and transfer it from the feeding conveyor line 710 to the receiving position on the conveyor rail 100. The pusher assembly includes a pusher drive and a pusher block. The pusher drive (e.g., a cylinder, electric cylinder, or linear motor) is fixedly mounted on the worktable, and its driving direction is perpendicular to the conveying direction of the feeding conveyor line 710. The pusher block is connected to the drive end of the pusher drive. The end of the pusher block facing the resistor has a pusher groove (not shown in the figure) adapted to the resistor to stably accommodate and limit the resistor during the pushing process, preventing its displacement.

Any equivalent structural transformations made based on the inventive concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
