Description

Technical Field

[0001] The invention relates to the technical field of chip mounters, and in particular to an auxiliary chip mount tooling for an LED chip mounter. Background Art

[0002] A chip mounter is a precision device used to automate the process of placing various electronic components on a circuit substrate at high speed and high precision. As a subdivision of chip mounters, LED bulk chip mounters focus on processing bulk LED components and accurately mounting them on circuit substrates. In the field of LED manufacturing, the application of such machines has greatly improved production efficiency and mounting accuracy, while effectively reducing the errors and costs that may be introduced by manual operations.

[0003] Auxiliary SMT tooling plays a vital role in the process of LED bulk SMT. Its design purpose is to optimize the processing flow of LED bulk chips and improve the efficiency and accuracy of SMT. This tooling usually integrates an advanced automatic feeding system to ensure that the circuit substrate can be smoothly and accurately delivered to the working area of ​​the SMT machine. Once the substrate is in place, the SMT machine will capture the LED component through its precise adsorption system, and then attach it to the specified position on the circuit substrate with extremely high precision. The automation and intelligence of this process significantly improves the continuity and efficiency of the production process.

[0004] In sharp contrast, traditional SMT tooling has obvious limitations in terms of material supply. They usually rely on a single material supply mechanism, and once the material is exhausted, the production line has to be stopped for refilling. This intermittent material supply not only interrupts the continuity of the production process and reduces overall production efficiency, but may also lead to a decrease in placement accuracy, because the instability of material supply increases the uncertainty in the placement process. In addition, frequent stoppages for refilling also increase unnecessary waste of production time, which has an adverse impact on production planning and cost control. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, a technical problem is to provide an auxiliary chip mounting tool for an LED chip mounting machine.

[0006] The technical solution is as follows: An auxiliary patch tooling for an LED patch machine includes a base frame, a motor, a screw, an abutment block, a slide rail, a U-shaped slider, a feed plate and a clamping assembly. A motor is installed on the left side of the base frame, a screw is connected to the motor output shaft, the screw is rotatably connected to the base frame, an abutment block is connected to the left side of the base frame, the screw passes through the abutment block, the top of the base frame is symmetrically connected to the slide rails, two U-shaped sliders are slidably connected between the slide rails, the U-shaped sliders are threadedly connected to the screw, the top of the U-shaped slider is connected to a feed plate for placing a substrate, and the U-shaped slider is provided with a clamping assembly for clamping the substrate.

[0007] Preferably, the clamping assembly includes a clamping frame, a push rod, a tension spring and a fixed rod. The U-shaped slider is slidably connected to the clamping frame, the clamping frame is slidably connected to the feeding plate, the middle part of the clamping frame is connected to the push rod, the push rod is slidably connected to the U-shaped slider, a tension spring is connected between the clamping frame and the U-shaped slider, the push rod is in contact with the corresponding abutment block, and the feeding plate is connected to a fixed rod on the side away from the clamping frame.

[0008] Preferably, it also includes a clamping piece, a clamping spring and a limit rod. The outer side of the feeding plate is slidably connected to the clamping piece, the limit rod is connected to the clamping piece, the limit rod is slidably connected to the feeding plate on the same side, and two clamping springs are connected between the clamping piece and the feeding plate on the same side.

[0009] Preferably, the inner portion of the clamping member is in a sloped shape.

[0010] Preferably, it also includes a connecting rod, an inclined block, a top frame, a sliding rod and a reset spring. The connecting rod is symmetrically connected to the inner side of the top of the base frame, and the inclined blocks are connected to both sides of the connecting rod. The feeding plate is slidably connected to the top frame for ejecting the material, and the sliding rod is symmetrically slidably connected to the lower side of the top frame. A reset spring is connected between the inside of the sliding rod and the top frame, and the sliding rod is in contact with the inclined block.

[0011] Preferably, both left and right side surfaces of the inclined block are inclined, and the inclined surfaces of the inclined blocks on both sides face opposite directions.

[0012] Preferably, it also includes a card bead and an elastic part. The card bead is symmetrically and slidingly connected to the lower side of the top frame. The elastic part is connected between the card bead and the inside of the top frame. A card groove is provided at a position aligned with the card bead on the feeding plate, and the card bead is engaged with the card groove.

[0013] Preferably, it also includes a support frame, a sliding frame, a flattening roller and a pressure spring. The support frame is symmetrically connected to the middle of the base frame, the sliding frame is slidably connected to the support frame, the sliding frame is rotatably connected to the flattening roller for flattening the substrate, and two pressure springs are connected between the sliding frame and the support frame.

[0014] The beneficial effects are: 1. Continuous loading and improved production efficiency: By setting two feeding plates on the base frame and configuring three workstations (left workstation, middle mounting workstation, and right workstation), this patented design realizes continuous loading of substrates. When one side of the substrate is receiving the mounting of LED components at the middle workstation, the operator can seamlessly unload and replenish the material on the other side without waiting for the mounting to be completed before operating. Compared with the single-threaded loading process in the prior art, this dual-line alternating loading method significantly improves the production efficiency and continuity of the production line, and avoids production interruptions caused by replenishment.

[0015] 2. Automatic clamping and quick unloading: The clamping frame and fixed rod set on the feeding plate, combined with the ingenious design of the abutment rod and the abutment block, realize the automatic limit of the substrate during loading. The clamping frame and the fixed rod automatically clamp the left and right sides of the substrate during the movement of the feeding plate to ensure stability during the mounting process. When the substrate and LED components are mounted and moved to the unloading position, the clamping frame automatically releases, which is convenient for the operator to quickly unload the workpiece. This function surpasses the manual or semi-automatic clamping and unloading mechanism in the existing technology and improves operating efficiency.

[0016] 3. Front and rear side clamping and enhanced stability: Additional clamps are installed on the feed plate, which can effectively clamp the front and rear sides of the substrate when placing the substrate, further improving the stability of the substrate during movement and placement. Compared with the problem of substrate shaking back and forth in the prior art, this design significantly improves the placement accuracy and finished product quality.

[0017] 4. Automatic positioning and unloading convenience: The patented positioning frame can automatically lift the tooling upward after the LED components are mounted, making it convenient for the operator to unload the tooling. The design of the card beads ensures that the positioning frame remains in the lifted state during the movement until the operator completes the unloading, avoiding the operational inconvenience caused by premature resetting of the positioning frame. Compared with the manual or semi-automatic unloading methods in the prior art, this innovation significantly improves the unloading speed and convenience.

[0018] 5. Substrate flatness and reliability: During the feeding process, the substrate will come into contact with the flattening roller, which ensures that the substrate is close to the feeding plate by applying appropriate pressure, effectively preventing the substrate from warping and ensuring the quality of the mounting tooling. Compared with the equipment in the prior art that may lack such a mechanism, this patented design significantly improves the flatness of the substrate through the flattening roller, thereby improving the mounting accuracy and reliability of LED components.

DETAILED DESCRIPTION

[0036] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1: An auxiliary chip mounting tool for an LED chip mounting machine, such as Figure 1-Figure 8 As shown, it includes a base frame 1, a motor 101, a screw 102, an abutment block 103, a slide rail 104, a U-shaped slider 105, a feed plate 106 and a clamping assembly. The motor 101 is installed on the left side of the base frame 1, and the screw 102 is connected to the output shaft of the motor 101. The screw 102 is rotatably connected to the base frame 1, and the abutment block 103 is connected to the left side of the base frame 1. The screw 102 penetrates the abutment block 103, and the top of the base frame 1 is symmetrically connected to the slide rail 104. Two U-shaped sliders 105 are slidably connected between the slide rails 104, and the U-shaped sliders 105 are threadedly connected to the screw 102. The device is divided into three stations, the middle station is used for patch work, and the stations on both sides are used for loading and unloading substrates. The two U-shaped sliders 105 move synchronously, and the tops of the U-shaped sliders 105 are connected to the feed plates 106 for placing substrates, and the U-shaped sliders 105 are provided with clamping assemblies for clamping the substrates.

[0038] like Figure 5-Figure 8 As shown, the clamping assembly includes a clamping frame 201, a push rod 202, a tension spring 203 and a fixed rod 204. The U-shaped slider 105 is slidably connected to the clamping frame 201, the clamping frame 201 is slidably connected to the feeding plate 106, the middle part of the clamping frame 201 is connected to the push rod 202, the push rod 202 is slidably connected to the U-shaped slider 105, a tension spring 203 is connected between the clamping frame 201 and the U-shaped slider 105, the push rod 202 is in contact with the corresponding abutment block 103, and the side of the feeding plate 106 away from the clamping frame 201 is connected to the fixed rod 204.

[0039] When performing the patch work of LED components, the substrate or PCB board can be placed on the feeding plate 106. The two feeding plates 106 form a feeding assembly. Initially, the feeding assembly is on the left. There are three stations on the chassis 1. The middle station is used for patch work, and the stations on both sides are used for loading and unloading of substrates. In normal use, the substrate of the feeding plate 106 on the right is in the middle station. When performing the patch work of LED components, the patch is completed by the patch machine. The main task of this device is to complete the loading and unloading operations of the substrate to assist the patch machine to complete the patch work of the LED components. The left feeding plate 106 is at the left station, in the state of placing a new substrate, and the right station is vacant. The motor 101 is linked with the patch machine. Once the LED component patch on the middle station is completed, the motor The machine 101 will start automatically, the output shaft of the motor 101 rotates to drive the screw 102 to rotate, and the screw 102 drives the U-shaped slider 105 and the feeding assembly to move to the right. This action makes the feeding plate 106 on the left enter the middle station, and the feeding plate 106 on the right moves to the right station. The clamping assembly will move synchronously with the feeding assembly. Initially, the abutment rod 202 on the left station abuts against the abutment block 103 on the left, and the tension spring 203 is in a stretched state. Because the abutment rod 202 abuts against the abutment block 103, when the feeding assembly drives the U-shaped slider 105 to move to the right along the slide rail 104, under the action of the tension spring 203, the U-shaped slider 105, the feeding plate 106 and the fixed rod 204 will move first, so that the feeding plate 106 moves with the substrate , the substrate is close to the clamping frame 201, and with the movement of the U-shaped slider 105, the tension spring 203 is gradually reset, the fixing rod 204 is against the left side of the substrate, and the clamping frame 201 is against the right side of the substrate. The pre-tightening force of the tension spring 203 can enable the clamping frame 201 to fix the substrate. After the clamping frame 201 is against the substrate, the push rod 202 continues to move with the feeding plate 106, thus realizing the function of automatically clamping the loaded substrate. In the initial working state, the push rod 202 of the middle station is disengaged from the abutment block 103 on the right, and the corresponding clamping frame 201 clamps the substrate in the middle station. When the feeding assembly moves, the right feeding plate 106 carries the workpiece with the completed patch to the right station, and the clamping assembly on the right feeding plate 106 moves with it. , when the push rod 202 moves to contact with the abutment block 103 on the right, the abutment block 103 abuts against the push rod 202, so that the push rod 202 and the clamping frame 201 stop moving, while the U-shaped slider 105 and the feeding plate 106 continue to move with the workpiece, the tension spring 203 will be stretched, and the clamping frame 201 is separated from the workpiece on which the patch has been completed, releasing the limit on the workpiece, so that the workpiece can be easily taken out, and then a new substrate is placed on the feeding plate 106 on the right. According to the operating procedure, the motor 101 will automatically pause after completing a movement to allow the operator to load and unload. After completing the patch tooling of an LED component, the motor 101 will start again, driving the feeding assembly to move in the opposite direction, realizing a left-right cyclic movement. During each pause,The middle station is used for patch work, and the side stations can load the substrate and unload the workpiece after patching, ensuring the continuous patching operation.

[0040] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 4 and Figure 5 As shown, it also includes a clamping piece 301, a clamping spring 302 and a limiting rod 303. The outer side of the feeding plate 106 is slidably connected with a clamping piece 301 for limiting the substrate, and the clamping piece 301 is connected to the limiting rod 303. The limiting rod 303 is slidably connected to the feeding plate 106 on the same side. Two clamping springs 302 are connected between the clamping piece 301 and the feeding plate 106 on the same side. The inner part of the clamping piece 301 is inclined, which is conducive to clamping the substrate.

[0041] When the substrate is placed on the feeding plate 106 at the corresponding position, the substrate can be moved along the inclined surface of the clamping piece 301, and the substrate will push the clamping piece 301 to move outward, and the limiting rod 303 moves outward with the clamping piece 301, and the clamping spring 302 is compressed, and the substrate is placed on the feeding plate 106 so that the outer wall of the substrate is against the limiting rod 303. The compressed force of the clamping spring 302 can make the clamping piece 301 limit the front and rear sides of the substrate. When the feeding plate 106 pushes the substrate to feed, the left and right side walls of the substrate are clamped and limited by the clamping frame 201 and the fixing rod 204, so as to improve the stability of the substrate. When the patch work is completed and the tooling with the patch is removed, the tooling can be directly moved upward and removed, and the tooling is separated from the contact with the clamping piece 301 and the limiting rod 303, and the clamping spring 302 rebounds and resets, so that the clamping piece 301 and the limiting rod 303 move inward and reset.

[0042] like Figure 9-14 As shown, it also includes a connecting rod 401, an inclined block 402, a top frame 403, a sliding rod 404, a return spring 405, a card bead 406 and an elastic member 407. The connecting rod 401 is welded symmetrically on the inner side of the top of the bottom frame 1. The inclined blocks 402 are welded on both sides of the connecting rod 401. The left and right sides of the inclined blocks 402 are both inclined. The inclined surfaces of the inclined blocks 402 on both sides face oppositely. The feed plate 106 is slidably connected to the top frame 403 for ejecting the material. The sides are symmetrically slidably connected with sliding rods 404, and return springs 405 are connected between the inside of the sliding rods 404 and the top frame 403. The sliding rods 404 are in contact with the inclined block 402, and the lower side of the top frame 403 is symmetrically slidably connected with clamping beads 406. Elastic parts 407 are connected between the clamping beads 406 and the inside of the top frame 403. The positions on the feeding plate 106 that are aligned with the clamping beads 406 are provided with clamping grooves, and the clamping beads 406 are clamped and matched with the clamping grooves to limit the top frame 403.

[0043] In the design, two feeding plates 106 form a feeding assembly, which is responsible for moving the feeding at intervals to the left and right to realize the patch process of the LED components and the substrate. When the feeding assembly moves from left to right, it means that the LED components of the middle station have been patched, the left station is preparing to feed the next substrate, and the right station is vacant, waiting to receive the workpiece with the completed patch. When the feeding assembly moves, the top frame 403 and the slide bar 404 move with it. In this process, the left slide bar 404 contacts the outer inclined surface of the left inclined block 402, and the right slide bar 404 contacts the right The inner inclined surface of the inclined block 402 contacts the inclined surface of the left inclined block 402, and the inclined surface design of the left inclined block 402 causes the left sliding rod 404 to move downward. At the same time, the return spring 405 is stretched. After the sliding rod 404 passes over the inclined block 402, it quickly returns to its original position under the elastic force of the return spring 405. At the same time, the inclined surface of the right inclined block 402 causes the right sliding rod 404 to move upward, thereby driving the top frame 403 and the clamping bead 406 to rise together. The rising action of the top frame 403 lifts up the workpiece that has been patched, and the clamping frame 201 and the clamping member 301 will not hinder the lifting of the workpiece. The clamping bead 406 06 is engaged with the slot inside the feed plate 106 during the rising process. The elastic member 407 plays a role of buffering and resetting in this process, ensuring that the card bead 406 can firmly fix the top frame 403, so that the workpiece remains in the top state. When the feeding assembly completes a moving cycle, the left feed plate 106 sends the LED component to the middle station for patching, and the right feed plate 106 sends the patched workpiece to the right station for unloading. The operator can easily unload the workpiece that has been patched, and then press down the top frame 403 on the right to make the card bead 406 move downward. 6 is disengaged from the card slot, completing the reset of the top frame 403. Then, the new substrate is added to the right feeding plate 106 to prepare for the next round of feeding and patch work. In this way, the feeding component realizes continuous movement and feeding from left to right. The ingenious design of the top frame 403 not only speeds up the operator's unloading process, but also does not interfere with the normal feeding operation. Similarly, when the feeding component moves from right to left, the contact direction between the slide bar 404 and the inclined surface of the inclined block 402 changes. Its operating principle is opposite to that when moving from left to right, and follows the same mechanical principle and operating process.

[0044] like Figure 1 , Fig.15 and Fig.16 As shown, it also includes a support frame 501, a sliding frame 502, a flattening roller 503 and a pressure spring 504. The support frame 501 is symmetrically connected to the middle part of the base frame 1 by bolts. The sliding frame 502 is slidably connected to the support frame 501. The sliding frame 502 is rotatably connected to the flattening roller 503 for flattening the substrate. Two pressure springs 504 are connected between the sliding frame 502 and the support frame 501. The height of the flattening roller 503 is slightly lower than the feeding plate 106.

[0045] After the substrate is loaded onto the feeding plate 106, the feeding assembly composed of the two feeding plates 106 is driven by the motor 101 to move, and the material is loaded and unloaded alternately left and right. When the feeding plate 106 moves with the substrate close to the middle station, the feeding plate 106 will contact the flattening roller 503, causing the flattening roller 503 to rotate due to friction. At the same time, the flattening roller 503 will be driven by the squeezing force to drive the sliding frame 502 to move up, and the pressure spring 504 is compressed. When the substrate on the feeding plate 106 contacts the flattening roller 503, the pressure of the pressure spring 504 can flatten the substrate by the flattening roller 503 to ensure that the substrate is close to the feeding plate 106 and avoid the substrate from warping. After breaking contact, the flattening roller 503 and the sliding frame 502 will rebound downward and reset due to the pressure spring 504. Such a design can improve the stability and accuracy of the substrate placement position.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
