Description

Technical Field

[0001] This utility model relates to the technical field of electronic component processing equipment, and in particular to a clamping mechanism and a resistor patch device. Background Technology

[0002] In the complex production process of the electronics manufacturing industry, the resistor placement process is undoubtedly a crucial step in the circuit board assembly process. The core task of this step is to accurately and precisely place the resistor components onto the pre-set designated positions on the circuit board with extremely high precision. In the entire resistor placement process, the clamping mechanism plays an extremely important role. It is responsible for efficiently and stably gripping and transferring the resistor components. The performance of the clamping mechanism directly determines the accuracy level of the placement operation and also has a significant impact on the integrity of the resistor components during the placement process. Therefore, a clamping mechanism and resistor placement device are particularly needed.

[0003] However, existing clamping mechanisms mostly use rigid clamping heads with fixed spacing, which are difficult to adapt to resistors of different specifications. They lack effective buffer structures, and rigid contact can easily damage resistors. They also lack precise limiting and correction functions, and resistors are prone to positional shifts when transported to the clamping station, leading to subsequent chip placement deviations and increasing product defect rates. This is incompatible with the high manufacturing precision requirements of miniaturized NTC chip resistors. They rely heavily on manual positioning and adjustment, which is not only labor-intensive but also makes it difficult to ensure operational consistency. The poor coordination of components can easily cause jamming or displacement of resistors during the process of transporting them to the clamping station, affecting the overall production rhythm.

This is incompatible with the high manufacturing precision requirements of miniaturized NTC chip resistors. They also rely heavily on manual positioning and adjustment, which is not only labor-intensive but also makes it difficult to ensure operational consistency. Furthermore, the poor coordination of various components makes it easy for the resistors to jam or shift during the process from transport to clamping, affecting the overall production rhythm.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a clamping mechanism and resistor patch device, including a worktable 1, a limiting block 2 fixedly installed on the outer side of the worktable 1, an electromagnetic slide rail 3 fixedly installed on the top of the worktable 1, a placement seat 4 slidably connected to the top of the electromagnetic slide rail 3, a fixing base 5 fixedly installed on the top of the worktable 1, a magnetic suction seat 6 fixedly installed on the top of the worktable 1, a correction component 7 provided on the top of the worktable 1, and a clamping component 8 provided on the top of the worktable 1; the clamping component 8 includes a mounting base 801, which is mounted on the worktable 1, a motor 802 fixedly installed on the top of the mounting base 801, a double-ended lead screw 803 with positive and negative threads fixedly installed at the output end of the motor 802, a positioning seat 804 threadedly connected to the outer side of the double-ended lead screw 803, and a mounting base plate 805 fixedly installed on the top of the worktable 1. An electric cylinder 806 is fixedly installed in the part. A telescopic rod 807 is fixedly installed at the movable end of the electric cylinder 806. A clamping head 808 is fixedly installed at the end of the telescopic rod 807 away from the electric cylinder 806. A connecting rod 809 is fixedly installed at the bottom of the clamping head 808. A clamping pad 810 is fixedly installed at the bottom of the connecting rod 809. By setting up the clamping assembly 8, the motor 802 drives the double-ended lead screw 803 with positive and negative threads, which drives the two sets of positioning seats 804 to move symmetrically. It can quickly adapt to the positioning requirements of resistors of different specifications. With the structural design of the positioning seat 804, it can form a stable lateral limit for the resistor. At the same time, the electric cylinder 806 drives the telescopic rod 807 to move the clamping head 808 and the clamping pad 810 at the bottom up and down, realizing the vertical clamping and fixing of the resistor. The dual clamping effect effectively prevents the resistor from shifting or falling off during the chip mounting process, and significantly improves the stability of clamping.

[0024] Furthermore, the correction component 7 includes a fixing block 701, which is mounted on the worktable 1. A sliding rail 702 is fixedly mounted on the outer side of the fixing block 701. A telescopic seat 703 is slidably connected to the top of the sliding rail 702. A connecting block 704 is fixedly mounted on the top of the telescopic seat 703. A correction roller 705 is fixedly mounted on the outer side of the connecting block 704. By setting the correction component 7, the correction roller 705 can correct the position of the resistor during the process of conveying it to the fixed base 5, ensuring that the resistor accurately enters the clamping position. The electromagnetic slide rail 3 drives the placement seat 4 to slide smoothly. Combined with the limiting effect of the limiting block 2, the accuracy of the resistor transfer position is guaranteed, providing a good positioning basis for subsequent chip placement operations and helping to improve the accuracy of resistor chip placement.

[0025] Furthermore, a protrusion is fixedly installed on the bottom of the placement seat 4, and two identical sets of limit blocks 2 are provided. The two sets of limit blocks 2 are symmetrically distributed about the vertical center line of the worktable 1. By setting two sets of limit blocks 2, the position of the resistor is prevented from deviating due to excessive displacement when the placement seat 4 slides on the electromagnetic slide rail 3, thus ensuring the accuracy of resistor transfer. This is especially suitable for the transfer operation of miniaturized chip resistors with extremely high positional accuracy requirements.

[0026] Furthermore, the electromagnetic slide rails 3 are provided in two identical sets, and the two sets of electromagnetic slide rails 3 are in contact with the fixed base 5. The height of the placement seat 4 is the same as the height of the fixed base 5. By setting two sets of electromagnetic slide rails 3 and fixed base 5, it is ensured that the placement seat 4 remains horizontal and stable during the transfer of the resistor. The consistent height of the placement seat 4 and the fixed base 5 allows the resistor to be smoothly transferred to the fixed base 5, avoiding changes in the resistor position caused by the height difference, which is conducive to maintaining the accurate positioning of the resistor.

[0027] Furthermore, the magnetic base 6 has a "side-convex" structure. The magnetic base 6 is in contact with the fixed base 5. By setting the magnetic base 6 and the fixed base 5, the stability of the resistor before clamping is further enhanced, preventing it from sliding during the waiting process for clamping. It works with the clamping component 8 to form multiple fixation, improving the overall reliability of the operation.

[0028] Furthermore, two identical sets of fixing blocks 701, sliding rails 702, telescopic seats 703, and connecting blocks 704 are provided, and the two sets of fixing blocks 701, sliding rails 702, telescopic seats 703, and connecting blocks 704 are symmetrically distributed about the vertical center line of the correcting roller 705. By setting two sets of fixing blocks 701, sliding rails 702, telescopic seats 703, and connecting blocks 704, the force on the correcting roller 705 is more balanced. When correcting the resistance, symmetrical forces can be applied from both sides, avoiding resistance skewing due to unilateral force, ensuring the accuracy of the correction effect, and making it suitable for the position correction of miniature resistors with high symmetry requirements.

[0029] Furthermore, the correction roller 705 is located between the two sets of connecting blocks 704. The correction roller 705 is in contact with the placement seat 4. By setting the correction roller 705 and the placement seat 4, the correction roller 705 can contact the resistor surface and perform rolling correction. This can not only achieve position correction, but also reduce frictional damage to the resistor surface through rolling contact. It is especially suitable for processing surface-sensitive semiconductor material resistors.

[0030] Furthermore, the positioning seats 804 are provided in two identical sets, and the two sets of positioning seats 804 are symmetrically distributed about the vertical center line of the double-ended lead screw 803. The positioning seats 804 have an "L" shape structure. By setting two sets of positioning seats 804, the resistor can be synchronously limited from both sides to ensure that the central axis of the resistor is consistent with the center of the fixed base 5. The "L" shape structure can limit the side and bottom of the resistor at the same time, which enhances the stability of positioning and is suitable for the positioning needs of NTC resistors of various specifications.

[0031] Furthermore, two identical sets of mounting base plates 805, electric cylinders 806, telescopic rods 807, clamping heads 808, connecting rods 809, and clamping pads 810 are provided, and the two sets of mounting base plates 805, electric cylinders 806, telescopic rods 807, clamping heads 808, connecting rods 809, and clamping pads 810 are located on both sides of the fixed base 5. By setting two sets of mounting base plates 805, electric cylinders 806, telescopic rods 807, clamping heads 808, connecting rods 809, and clamping pads 810, the resistor is vertically clamped from both sides of the fixed base 5, which can ensure the balance of clamping force and avoid deformation or damage to the resistor due to excessive force on one side. At the same time, it improves the adaptability to resistors of different widths and expands the application range of the device.

[0032] Furthermore, the clamping pad 810 and the positioning seat 804 do not contact each other, while the clamping pad 810 contacts the fixed base 5. By setting the clamping pad 810 and the positioning seat 804, interference between the two during operation is avoided, ensuring the independent realization of their respective functions. The contact between the clamping pad 810 and the fixed base 5 can form a flexible clamping of the resistor through the elastic deformation of the clamping pad 810. While ensuring a firm clamping, it effectively buffers the clamping force and prevents damage to the resistor. It is particularly suitable for clamping operations of fragile miniature semiconductor resistors.

[0033] Working principle: First, the operator places the resistor to be mounted on the mounting base 4. The protrusion at the bottom of the mounting base 4 matches the electromagnetic slide rail 3, ensuring the resistor is placed stably. At this time, two sets of symmetrically distributed limiting blocks 2 limit the sliding range of the mounting base 4 to prevent excessive displacement. The operator then activates the electromagnetic slide rail 3. Under the action of the two sets of electromagnetic slide rails 3, the mounting base 4 slides smoothly towards the fixed base 5. Since the height of the mounting base 4 is the same as that of the fixed base 5, the resistor can smoothly transition onto the fixed base 5, avoiding positional changes due to height differences. During the process of the resistor being moved from the placement seat 4 to the fixed base 5, the correction component 7 begins to operate. The telescopic seat 703 adjusts along the sliding rail 702 to the position that matches the resistor size. Two sets of symmetrically distributed fixing blocks 701, sliding rails 702, and other components ensure that the correction roller 705 is subjected to balanced force. The correction roller 705 contacts and rolls with the resistor surface to correct the resistor's position, ensuring that it accurately enters the clamping position and reducing placement errors caused by positional misalignment. When the resistor reaches the fixed base 5, the magnetic seat 6 engages with the fixed base 5 to generate an attractive force on the resistor, preventing it from being pulled away. While waiting to be clamped, the resistor slides, forming a preliminary fixation. The operator activates the clamping assembly 8, and the motor 802 drives the double-ended lead screw 803 with positive and negative threads to rotate, causing the two sets of positioning seats 804 to move symmetrically along the lead screw, forming a stable lateral limit on the resistor from both sides, ensuring that the central axis of the resistor is aligned with the center of the fixed base 5. Subsequently, the electric cylinder 806 drives the telescopic rod 807 to extend, causing the clamping head 808, connecting rod 809, and clamping pad 810 to move downwards. The clamping pad 810 contacts the fixed base 5, forming a vertical flexible clamp on the resistor through elastic deformation. Furthermore, the clamping pad 810 and the positioning seat 804 do not interfere with each other, achieving dual stable clamping. After clamping and positioning are completed, the external mounting mechanism performs a precise mounting operation on the fixed resistor, attaching the resistor to the designated position on the circuit board. After mounting is completed, the electric cylinder 806 drives the telescopic rod 807 to retract, the clamping head 808 and the clamping pad 810 reset, the motor 802 drives the double-ended lead screw 803 with positive and negative threads to rotate in the opposite direction, the positioning seat 804 returns to its original position to release the resistor, and the electromagnetic slide rail 3 drives the placement seat 4 back to its initial position, ready for the next operation, realizing continuous production.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
