Description

Technical Field

[0001] The present invention relates to the technical field of LED patch bracket processing, and in particular to an LED patch bracket conveying device and an LED patch bracket injection molding device. Background Art

[0002] The LED bracket is the bottom base of the LED lamp bead before encapsulation. The LED chip is fixed on the LED bracket, and then the positive and negative electrodes are welded, and then the glue is sealed and formed.

[0003] LED brackets generally include straight plug-in brackets, piranha brackets, patch brackets, etc. Among them, LED patch brackets are generally produced and processed through the processes of stamping, electroplating, injection molding, blanking, and packaging. During the injection molding process, a single large reel rewinder is generally required. When the single large reel runs out of material and needs to change the material, it needs to stop the machine to operate. This not only reduces the work efficiency, but also during the shutdown process, because the rubber material stays in the screw of the injection molding machine for too long, the rubber material is prone to aging and yellowing, resulting in the need to re-dissolve the glue and inject the glue, causing waste of the rubber material and making the product quality unstable.

[0004] Therefore, there is an urgent need to provide an LED patch bracket conveying device and an LED patch bracket injection molding device that can improve production efficiency and product quality. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide an LED patch bracket conveying device and an LED patch bracket injection molding device to solve the technical problems of low production efficiency and unstable product quality existing in the processing of LED patch brackets in the prior art.

[0006] In a first aspect, an embodiment of the present invention provides an LED patch bracket conveying device, including: a frame; a feeding mechanism disposed on the frame, including a feeding reel and a feeding turntable. The feeding reel is used to drive the rotation of a to-be-processed tape reel with a tape amount greater than a preset amount. Multiple LED patch brackets are formed on the to-be-processed tape. The feeding turntable is used to receive the remaining to-be-processed tape reel and further feed the tape. During the feeding process, the LED patch brackets are processed in batches in a predetermined quantity. When the feeding turntable is working, the feeding reel can receive a new to-be-processed tape reel to drive the new to-be-processed tape reel, so as to perform a new round of feeding; a receiving mechanism disposed on the frame, used to wind the processed tape, and the wound processed tape is wound into a processed tape reel.

[0007] Further, a to-be-processed tape roll with a tape quantity greater than a preset tape quantity rotates under the drive of a feeding reel to release the to-be-processed tape for feeding. The to-be-processed tape roll is formed by winding the to-be-processed tape multiple times. The remaining to-be-processed tape roll is obtained by feeding the to-be-processed tape roll multiple times and meeting the condition of being less than or equal to the preset tape quantity. The feeding turntable drives the remaining to-be-processed tape roll to rotate to further release the to-be-processed tape for further feeding. The processed tape is formed after the LED patch brackets on the to-be-processed tape have been processed. The receiving mechanism includes a receiving reel and a receiving turntable. The receiving reel is used to wind the processed tape to obtain a processed tape roll. When the processed tape roll reaches the preset winding quantity, the processed tape is cut off. The receiving turntable is used to wind the remaining processed tape that will be formed after cutting off.

[0008] Further, the feeding mechanism further includes a feeding sensor and a feeding motor. The feeding sensor is used to detect the to-be-processed tape passing through it, and the feeding motor is used to drive the rotation of the feeding turntable. When the feeding sensor detects that the to-be-processed tape meets the first preset condition, the feeding motor is controlled to stop working, so as to wait for the LED patch brackets on the to-be-processed tape sent to the processing position to be processed. When the feeding sensor detects that the to-be-processed tape does not meet the first preset condition, the feeding motor is controlled to start working, so that after the LED patch brackets are processed at the processing position, the feeding motor further drives the feeding turntable to release the to-be-processed tape to drive the to-be-processed LED patch brackets to be transported to the processing position.

[0009] Further, the receiving mechanism includes a receiving sensor and a receiving motor. The receiving sensor is used to detect the processed tape passing through it, and the receiving motor is used to drive the rotation of the receiving turntable. When the receiving sensor detects that the processed tape meets the second preset condition, the receiving motor is controlled to stop working, so as to wait for the LED patch brackets on the to-be-processed tape sent to the processing position to be processed. When the receiving sensor detects that the processed tape does not meet the second preset condition, the receiving motor is controlled to start working, so that after the LED patch brackets are processed at the processing position, the receiving motor further drives the receiving turntable to wind the processed tape.

[0010] Further, both the feeding sensor and the receiving sensor are set as pressure sensors. The first preset condition is set as the pressure value applied by the to-be-processed tape to the feeding sensor being greater than the first preset pressure value. The second preset condition is set as the pressure value applied by the processed tape to the receiving sensor being equal to the second preset pressure value. Or, both the feeding sensor and the receiving sensor are set as speed sensors. The first preset condition is set as the speed value of the relative movement of the to-be-processed tape on the feeding sensor being greater than the first preset speed value. The second preset condition is set as the speed value of the relative movement of the to-be-processed tape on the receiving sensor being equal to the second preset speed value.

[0011] Further, the frame includes a support and a support column. The support column is fixedly connected to the support and extends in the vertical direction. The feeding turntable and the receiving turntable are rotatably and vertically mounted on the support column. The feeding turntable is located above the receiving turntable in the vertical direction and the respective rotation axes of the two turntables are arranged in parallel. The support rotatably supports the feeding reel and the receiving reel. The feeding reel and the receiving reel are horizontally spaced and parallel in the vertical direction, and the feeding reel is located above the receiving reel in the vertical direction.

[0012] Further, the support includes four support seat plates that are horizontally spaced and parallel in the vertical direction. The four support seat plates are successively formed into a first-layer support seat plate, a second-layer support seat plate, a third-layer support seat plate, and a fourth-layer support seat plate from top to bottom in the vertical direction. The first-layer support seat plate and the second-layer support seat plate respectively rotatably support a feeding reel. The two feeding reels synchronously drive the to-be-processed tape reels thereon for synchronous feeding. And the two feeding reels share a feeding turntable. Thus, when the to-be-processed tape reel driven by one of the two feeding reels obtains a remaining to-be-processed tape reel after multiple feedings, the remaining to-be-processed tape reel is transferred and placed on the feeding turntable. The third-layer support seat plate and the fourth-layer support seat plate respectively rotatably support a receiving reel. The two receiving reels share a receiving turntable. Thus, the two receiving reels can simultaneously wind the processed tape reels. And when the processed tape reel on one of the two receiving reels reaches a preset winding amount and needs to be cut off, the cut head corresponding to the remaining processed tape formed after cutting is wound around the receiving turntable and thus is wound as the receiving turntable rotates.

[0013] Further, the LED patch bracket conveying device further includes a support arm, two first coil thickness detectors, two second coil thickness detectors, and a reminder. The support arm is fixed on the first layer of support seat plate and suspends and supports a first coil thickness detector thereon. The first coil thickness detector faces the feeding coil reel rotatably supported on the upper side of the first layer of support seat plate and is used to detect the thickness of the to-be-processed tape coil driven by the feeding coil reel. Another first coil thickness detector is arranged on the lower side of the first layer of support seat plate. Another first coil thickness detector faces another feeding coil reel rotatably supported on the second layer of support seat plate and is used to detect the thickness of the to-be-processed tape coil driven by another feeding coil reel. A second coil thickness detector is respectively arranged on the lower sides of the second layer of support seat plate and the second layer of support seat plate. The two first coil thickness detectors respectively face the take-up coil reels rotatably supported on the second layer of support seat plate and the third layer of support seat plate, and are respectively used to detect the thickness of the processed tape coils respectively wound by the two take-up coil reels. When at least one of the two first coil thickness detectors detects that the thickness of the remaining to-be-processed tape coil corresponds to less than the preset tape amount, the reminder is triggered to work to remind to transfer and place the detected remaining to-be-processed tape coil on the feeding turntable. When at least one of the two second coil thickness detectors detects that the thickness of the processed tape coil corresponds to the preset winding amount, the reminder is triggered to work to remind to cut off the processed tape and wind the cut head of the remaining processed tape onto the take-up turntable.

[0014] Further, the frame further includes a support platform. The LED patch bracket conveying device further includes two separator paper coil reels and two third coil thickness detectors arranged on the support platform. The two sides of the support platform are respectively fixedly connected to the four support seat plates and the columns. The two separator paper coil reels are respectively used to separate the separator paper between every two adjacent circles of the to-be-processed tape driven by a feeding coil reel and wind it into a separator paper coil. Hollow parts are provided on both of the two separator paper coil reels. The two third coil thickness detectors are respectively spaced in the vertical direction below the two hollow parts. The third coil thickness detector includes a signal transmitter and a signal receiver. The two third coil thickness detectors respectively emit signals to the hollow arc through the signal transmitter, and detect whether the separator paper coil reaches the preset thickness by receiving whether there is a signal reflected back by the separator paper coil through the signal receiver. The preset thickness has a corresponding relationship with the preset tape amount. When at least one of the two third coil thickness detectors detects that the separator paper coil reaches the preset thickness, the reminder is triggered to work to remind to transfer and place the remaining to-be-processed tape coil on the feeding coil reel corresponding to the detected separator paper coil on the feeding turntable.

[0015] Second aspect, an embodiment of the present invention further provides an LED patch bracket injection molding device, including an LED patch bracket injection molding device and any one of the above LED patch bracket conveying devices. The LED patch bracket injection molding device is provided with a processing position for injection molding. The LED patch bracket injection molding device applies a traction force to the strip to be processed that moves from the feeding mechanism to the processing position, and applies a pushing force to the processed strip that moves from the processing position to the receiving mechanism.

[0016] Beneficial effects of the present invention:

[0017] The LED patch bracket conveying device and the LED patch bracket injection molding device provided by the present invention use a feeding reel and a feeding turntable in the feeding mechanism to feed the strip to be processed, and the feeding turntable plays a role in transitional feeding, providing sufficient time for the user to place a new strip to be processed reel, so as to realize that the processing device continuously and highly automatically processes the LED patch brackets on each strip to be processed of a predetermined length, and avoids the processing device from stopping to wait for the feeding reel to change materials, and at the same time avoids the adverse impact of the processing device stopping on the processing quality, significantly improving the product quality of the processed LED patch brackets.

If there is no conflict, the embodiments of the present invention and the various features in the embodiments may be combined with each other, and all are within the protection scope of the present invention.

[0027] Refer to Figures 1 to 4, as an object of the present invention, there is provided an LED chip bracket conveying device 10, including: a frame 1, a feeding mechanism 2 and a receiving mechanism 3 respectively arranged on the frame 1. The feeding mechanism 2 includes a feeding reel 21 and a feeding turntable 22. The feeding reel 21 is used to drive the rotation of a to-be-processed tape roll with a tape amount greater than a preset tape amount, so as to release the to-be-processed tape 20 for feeding. That is to say, when releasing the to-be-processed tape 20 for feeding, the to-be-processed tape roll is unrolled, straightened and fed to the processing device under the traction force of the LED chip bracket conveying device 10 and the processing device, one circle by one circle from the outside to the inside. The to-be-processed tape roll is formed by winding the to-be-processed tape 20 for multiple circles. A plurality of LED chip brackets (not shown) are formed on the to-be-processed tape 20. In the present invention, the to-be-processed tape 20 is specifically a copper tape, and a plurality of LED chip brackets (not shown) arranged in an array form have been formed on the to-be-processed tape 20 through a previous stamping process. The to-be-processed tape roll initially placed on the feeding reel 21 generally has a relatively large weight, such as 200 to 300 catties. Preferably, a circle of isolation paper tape is arranged between every two adjacent circles of the to-be-processed tape 20 of the to-be-processed tape roll. The isolation paper tape is in a roll shape and clamps a to-be-processed tape 20 between every two circles, so as to reduce the secondary pollution to the LED chip brackets during the processing process.

[0028] The feeding turntable 22 is used to receive the remaining to-be-processed tape roll with a tape amount less than or equal to the preset tape amount obtained after multiple feedings of the to-be-processed tape roll. When most of the to-be-processed tape 20 has been fed and processed, the weight of the remaining to-be-processed tape roll is greatly reduced, and the user can manually or operate a simple tool to carry the remaining to-be-processed tape roll onto the feeding turntable 22. The preset tape amount can be determined according to the convenience of the user in carrying the remaining to-be-processed tape roll, the time-consuming duration, the processing speed of the to-be-processed tape 20, etc., and is in a proportional relationship with the radial thickness value of the to-be-processed tape roll. The feeding turntable 22 drives the rotation of the remaining to-be-processed tape roll to further release the to-be-processed tape 20, so as to achieve continuous feeding. During the feeding process, the LED chip brackets are processed in batches in a predetermined quantity. For example, an LED chip bracket injection molding device 40 is used as the processing device to inject and process the LED chip brackets on the to-be-processed tape 20 with a predetermined length entering it during feeding. The processing quantity of each injection molding operation can be set according to actual needs. When the feeding turntable 22 is working, the feeding reel 21 can receive a new to-be-processed tape roll to drive the new to-be-processed tape roll for a new round of feeding.

[0029] The material receiving mechanism 3 is used to wind the processed tape 30. The processed tape 30 is formed after the LED patch bracket on the to-be-processed tape 20 is processed. The wound processed tape 30 is wound into a processed tape roll. When a section of the to-be-processed tape 20 is processed in the processing device, this section of the tape becomes the processed tape 30. Thus, while the material feeding mechanism 2 feeds the tape, the material receiving mechanism 3 receives the tape, and the processed tape 30 is gradually wound into a processed tape roll.

[0030] As described above, since the material feeding mechanism 2 of the LED patch bracket conveying device 10 provided by the present invention uses the material feeding reel 21 and the material feeding turntable 22 to feed the to-be-processed tape 20, the material feeding turntable 22 plays a role in transitional feeding, providing sufficient time for the user to place a new to-be-processed tape roll, so as to realize that the processing device continuously and highly automatically processes the LED patch brackets on each predetermined length of the to-be-processed tape 20. This avoids the processing device from stopping to wait for the replacement of the material on the material feeding reel 21, and at the same time avoids problems such as the glue material being prone to aging and yellowing and needing to re-dissolve the glue when the LED patch bracket injection molding device 40 stops, significantly improving the product quality of the processed LED patch brackets.

[0031] Please refer to Figure 1 and Figure 2 Specifically, the material receiving mechanism 3 includes a material receiving reel 31 and a material receiving turntable 32. The material receiving reel 31 is used to wind the processed tape 30 to form a processed tape roll. When the processed tape roll reaches the preset winding amount, the processed tape 30 can be manually cut off by tools such as scissors. The material receiving turntable 32 is used to wind the remaining processed tape 30 after cutting. The preset winding amount can be determined according to the convenience of the user in carrying the processed tape roll, the time-consuming duration, the processing speed, etc., and is in a proportional relationship with the radial thickness value of the processed tape roll. Therefore, the material receiving mechanism 3 uses the material receiving reel 31 and the material receiving turntable 32 to wind the processed tape 30. The material receiving turntable 32 plays a role in transitional receiving, providing sufficient time to move the processed tape 30 on the material receiving reel 31 away, while ensuring the continuous operation of the LED patch bracket conveying device 10, and further ensuring that the processing device continuously and highly automatically processes the LED patch brackets on each predetermined length of the to-be-processed tape 20.

[0032] Please refer to Figure 1 and Figure 2, Preferably, the feeding mechanism 2 further includes a feeding sensor 23 and a feeding motor 24. The feeding sensor 23 is used to detect the to-be-processed strip 20 passing through it, and the feeding motor 24 is used to drive the rotation of the feeding turntable 22. When the feeding sensor 23 detects that the to-be-processed strip 20 meets the first preset condition (for example, the pressure value applied to the feeding sensor 23 is greater than zero or the relative speed is greater than zero), the feeding motor 24 is controlled to stop working, and wait for the LED patch holder on the to-be-processed strip 20 to be processed. When the feeding sensor 23 detects that the to-be-processed strip 20 does not meet the first preset condition (for example, there is no pressure or no relative movement), the feeding motor 24 is controlled to start working. Thus, after the processing is completed, the feeding motor 24 drives the feeding turntable 22 to release the to-be-processed strip 20 and convey the to-be-processed LED patch holder to the processing position. The feeding sensor 23 can accurately judge whether the to-be-processed strip 20 is in the processed state, so as to accurately control the start and stop of the feeding motor 24 and ensure the accurate feeding of the feeding turntable 22.

[0033] Please refer to Figure 1 and Figure 2 , Preferably, the receiving mechanism 3 further includes a receiving sensor 33 and a receiving motor 34. The receiving sensor 33 is used to detect the processed strip 30 passing through it, and the receiving motor 34 is used to drive the rotation of the receiving turntable 32. When the receiving sensor 33 detects that the processed strip 30 meets the second preset condition (for example, the pressure value is equal to zero or the relative speed is equal to zero), the receiving motor 34 is controlled to stop working, and wait for the LED patch holder on the to-be-processed strip 20 to be processed. When the receiving sensor 33 detects that the processed strip 30 does not meet the second preset condition (for example, there is pressure or relative movement), the receiving motor 34 is controlled to start working. Thus, after the processing is completed, the receiving motor 34 drives the receiving turntable 32 to wind up the processed strip 30. The receiving sensor 33 can accurately judge whether the to-be-processed strip 20 is in the processed state, so as to accurately control the start and stop of the receiving motor 34 and ensure the accuracy of receiving.

[0034] Please refer to Figure 2, specifically, both the feeding sensor 23 and the receiving sensor 33 are pressure sensors. The first preset condition is set such that the pressure value applied by the strip to be processed 20 on the feeding sensor 23 is greater than the first preset pressure value (e.g., 0), and the second preset condition is set such that the pressure value applied by the processed strip 30 on the receiving sensor 33 is equal to the second preset pressure value (e.g., 0). When processing is carried out at the processing position, the strip to be processed 20 is not subjected to a traction force and the processed strip 30 is not subjected to a pushing force. The strip to be processed 20 sags under its own weight and presses down on the feeding sensor 23. At this time, the feeding sensor 23 detects that the pressure value is greater than 0, and the feeding motor 24 stops working. After processing is completed, the strip to be processed 20 is subjected to a traction force and moves away from the feeding sensor 23. At this time, the feeding sensor 23 does not detect a pressure value, and the feeding motor 24 starts working. At the same time, the processed strip 30 is subjected to a pushing force and moves away from the receiving sensor 33. At this time, the receiving sensor 33 does not detect a pressure value, and the receiving motor 34 starts working. In this way, the feeding motor 24 and the receiving motor 34 are synchronously started to coordinate the feeding and receiving.

[0035] Please refer to Figure 1 and Figure 3 , preferably, the frame 1 includes a support 11 and a support column 12. The support column 12 is fixedly connected to the support 11 and extends in the vertical direction. The feeding turntable 22 and the receiving turntable 32 are rotatably and vertically mounted on the support column 12. The feeding turntable 22 is located above the receiving turntable 32, and the rotation axes of the two turntables are parallel. The feeding reel 21 and the receiving reel 31 are rotatably supported on the support 11. The feeding reel 21 and the receiving reel 31 are horizontally spaced and parallel in the vertical direction, and the feeding reel 21 is located above the receiving reel 31. This layout makes the feeding mechanism 2 and the receiving mechanism 3 compact, facilitating the smooth and accurate displacement of the strip to be processed 20 and the processed strip 30 during the feeding and receiving processes.

[0036] Please refer to Figure 1, specifically, the support 11 includes four support seat plates 111 that are horizontally spaced and parallel in the vertical direction. The four support seat plates 111 are successively formed as the first-layer support seat plate, the second-layer support seat plate, the third-layer support seat plate, and the fourth-layer support seat plate from top to bottom in the vertical direction. The first-layer support seat plate and the second-layer support seat plate respectively rotatably support a feeding reel 21. The two feeding reels 21 synchronously drive the processing material tape reels thereon for synchronous feeding, and the two feeding reels 21 share a feeding turntable 22. When the processing material tape reel driven by one of the two feeding reels 21 obtains a remaining processing material tape reel after multiple feedings, the remaining processing material tape reel is transferred and placed on the feeding turntable 22. Generally, the two processing material tapes 20 with LED patch holders are injection-molded at two different processing positions by two different injection molds of the LED patch holder injection molding device 40. Either the lengths of the two processing material tapes 20 entering the two different processing positions are different, or the initial thicknesses of the two processing material tape reels are different from each other. Therefore, the probability that the remaining processing material tape reels obtained after feeding both need to be transferred to the feeding turntable 22 simultaneously is very low. Therefore, setting a shared feeding turntable 22 can simplify the structure and reduce costs.

[0037] The third-layer support seat plate and the fourth-layer support seat plate respectively rotatably support a winding reel 31. The two winding reels 31 share a winding turntable 32, so that the two winding reels 31 wind the processed material tape reels simultaneously. When the processed material tape reel on one of the two winding reels 31 reaches the preset winding amount and needs to be cut off, the cut-off head corresponding to the remaining processed material tape 30 to be formed after cutting is wound onto the winding turntable 32 and thus wound as the winding turntable 32 rotates. For the same reason that the probability that the two remaining processing material tape reels need to be transferred to the feeding turntable 22 simultaneously is very low, the probability that the two processed material tape reels need to be cut off simultaneously so that the cut-off heads of the two remaining processed material tapes 30 to be formed need to be wound onto the winding turntable 32 simultaneously is very low. Therefore, setting a shared winding turntable 32 can further simplify the structure and reduce costs. In summary, the LED patch holder conveying device 10 uses two feeding reels 21 for feeding and two winding reels 31 for winding, which can increase the total number of LED patch holders processed in one processing operation, thereby improving the processing efficiency. And by sharing a feeding turntable 22 and a winding turntable 32, it can not only ensure continuous feeding and material supply, but also simplify the structure and reduce costs.

[0038] Please refer to Figure 1 and Figure 2, preferably, the LED patch bracket conveying device 10 further includes a support arm (not shown), two first roll thickness detectors, two second roll thickness detectors, and a reminder. The support arm is fixed to the first layer of the support seat plate and suspends and supports a first roll thickness detector on the support arm. The reminder can specifically adopt a voice broadcaster, a display, etc. In the present invention, the reminder all adopts a voice broadcaster. The first roll thickness detector faces the feeding reel 21 rotatably supported on the upper side of the first layer of the support seat plate and is used to detect the thickness of the to-be-processed tape roll driven by the feeding reel 21. Another first roll thickness detector is arranged on the lower side of the first layer of the support seat plate. Another first roll thickness detector faces another feeding reel 21 rotatably supported on the second layer of the support seat plate and is used to detect the thickness of the to-be-processed tape roll driven by another feeding reel 21. A second roll thickness detector is respectively arranged on the lower sides of the second layer of the support seat plate and the third layer of the support seat plate. The two first roll thickness detectors respectively face the take-up reels 31 rotatably supported on the second layer of the support seat plate and the third layer of the support seat plate, and are respectively used to detect the thickness of the processed tape rolls respectively wound by the two take-up reels 31. When at least one of the two first roll thickness detectors detects that the thickness of the remaining to-be-processed tape roll corresponds to less than the preset tape amount, the reminder receives the control instruction generated according to the detection result and is triggered to work to emit the voice information pre-stored in, for example, the storage to prompt to transfer and place the detected remaining to-be-processed tape roll on the feeding turntable 22. When at least one of the two second roll thickness detectors detects that the thickness of the processed tape roll corresponds to the preset winding amount, the reminder is correspondingly triggered to work to emit the corresponding voice information to prompt to cut off the processed tape 30 and wind the cut head of the remaining processed tape around the take-up turntable 32. Specifically, the first roll thickness detector and the second roll thickness detector can both include a signal transmitter and a signal receiver. They detect the thickness of the to-be-processed tape roll or the processed tape roll by judging whether the signal emitted by the signal transmitter is reflected to the corresponding signal receiver by the to-be-processed tape 20 or the processed tape 30. When the feeding turntable 22 and the take-up turntable 32 perform the functions of transitional feeding and transitional take-up, time can be respectively saved for replacing a new to-be-processed tape roll onto the feeding reel 21 and transferring the processed tape roll on the take-up reel 31. After the replacement and transfer are completed, the front free end of the to-be-processed tape 20 of the new to-be-processed tape roll is timely connected to the tail free end of the to-be-processed tape 20 exposed after continuous feeding on the feeding turntable 22 through tape or masking paper, etc., and the processed tape 30 wound with the preset thickness on the take-up turntable 32 is timely cut off and the cut head of the processed tape 30 on one side of the processing device is wound around the empty take-up reel 31.Therefore, by setting two first coil thickness detectors and two second coil thickness detectors, the LED patch bracket conveying device 10 can timely and accurately detect the thicknesses of the remaining to-be-processed strip coils and the processed strip coils corresponding on the feeding reel 21 and the receiving reel 31, so as to use the prompt device to prompt corresponding information to remind the user to perform corresponding operations in time. It not only has a high degree of automation, but also avoids the user's continuous visual observation, saves manpower, ensures the continuous feeding and receiving of the LED patch bracket conveying device 10, significantly improves the production efficiency and enhances the processing quality of the product.

[0039] Please refer to Figure 1 and Figure 4, preferably, the frame 1 further includes a support platform 13, and the LED chip carrier conveying device 10 further includes two separator paper reels 5 and two third reel thickness detectors disposed on the support platform 13. The above-mentioned prompt device can be disposed on the support platform 13. Both sides of the support platform 13 are fixedly connected to four support seat plates 111 and columns 12 respectively. The two separator paper reels 5 are respectively driven by two paper reel motors to separate the separator paper between every two adjacent coils of the to-be-processed tape 20 driven by a feeding reel 21 and wind it into a separator paper reel. The separator paper specifically uses sulfur-free paper. Preferably, in the vertical direction, the two separator paper reels 5 are respectively higher than the two feeding reels 21, which is more convenient for separating the separator paper. In this embodiment, the two separator paper reels 5 are respectively fixedly connected to the support platform 13 through a support plate 6. The first extension direction of the four support seat plates 111 away from the support platform 13 is perpendicular to the second extension direction of the two support plates 6 with respect to the support platform 13, which is convenient for the related operations of the to-be-processed tape reel, the processed tape reel, and the separator paper reel to have independent operation spaces, without interference from each other, and is convenient for intuitively observing the working states of each reel and each turntable. Both of the two separator paper reels 5 are provided with hollow portions, and the hollow portions can be a plurality of hollow arcs whose central arcs pass through the same concentric circle. The two third reel thickness detectors are respectively spaced in the vertical direction below the two hollow portions. The third reel thickness detector includes a signal transmitter and a signal receiver. The two third reel thickness detectors respectively emit signals to the hollow arcs through the signal transmitter, and detect whether the separator paper reel reaches a preset thickness by receiving whether the signals reflected by the separator paper reel 5 are received by the signal receiver. The preset thickness can be set to have a corresponding relationship in conversion proportion with the preset tape amount. When at least one of the two third reel thickness detectors detects that the separator paper reel reaches the preset thickness, the prompt device is triggered to work to prompt to transfer and place the remaining to-be-processed tape reel on the feeding reel 21 corresponding to the detected separator paper reel on the feeding turntable 22. It can be known that the LED chip carrier conveying device 10 includes a control device such as a CPU, a PLC, etc. The control device includes a memory and a controller. The control device is electrically connected to each sensor and each reel thickness detector. The memory stores a corresponding relationship table and corresponding detection result information of the thickness of the to-be-processed tape reel and the processed tape reel respectively detected by the first reel thickness detector and the second reel thickness detector with the preset tape amount and the preset winding amount. Similarly, the memory also stores a corresponding relationship table of the thickness of the separator paper reel detected by the third reel thickness detector with the preset tape amount and the corresponding detection result information. The controller controls the work of each motor and the prompt device according to the received detection result information.It can be seen that the LED patch bracket conveying device 10 detects the thickness of the isolation paper tape roll respectively through the two third roll thickness detectors provided. Since there are certain differences in thickness and ductility between the isolation paper tape and the tape to be processed, and there is a certain corresponding relationship between them in terms of length. Also, since the thickness of the isolation paper tape roll is also in a corresponding relationship with the preset tape amount, that is to say, the decrease in the thickness of the tape roll to be processed is in an inverse proportion and in a certain ratio to the increase in the thickness of the isolation paper tape roll. Therefore, not only can the isolation paper be separated and wound by the two isolation paper reels 5, but the two third roll thickness detectors can timely and accurately detect the thicknesses of the two isolation paper reels respectively, thus equivalently detecting the thicknesses of the remaining tape rolls to be processed on the two feeding reels 21 in a timely and accurate manner. Furthermore, the reminder prompts the corresponding information to remind the user to perform the corresponding operations in a timely manner, with a high degree of automation, significantly improving the production efficiency and the processing quality of the product.

[0040] For the embodiment of the LED patch bracket conveying device 10 that adopts two isolation paper reels 5 and two third roll thickness detectors, not only can the third roll thickness detectors detect the thicknesses of the two isolation paper reels 5 to correspondingly detect the thicknesses of the remaining tape rolls to be processed on the two feeding reels 21, but also the detected thicknesses of the two isolation paper reels 5 can be used as the reminder information for triggering the need to transfer the two isolation papers pre-stored in the memory for the reminder to prompt the user so as to perform the corresponding operations in a timely manner.

[0041] In addition, as another improvement, it is known that the LED patch bracket conveying device 10 has reel motors for driving each feeding reel 21, each winding reel 31 and each isolation paper reel 5 respectively. The controller can automatically and coordinately control the start and stop of each reel motor, the feeding motor 24 and the winding motor 34 according to the detection results of each detector and each sensor, so that they work together in a coordinated manner. For example, the reel motor of the isolation paper reel 5 and the reel motor of the corresponding feeding reel 21 or the reel motor of the feeding turntable 22 are controlled to start and stop synchronously. Another example is that when the first roll thickness detector detects that the thicknesses of the tape rolls to be processed are respectively less than the preset tape amount, the reel motor of the feeding reel 21 is correspondingly shut down, and the feeding motor 24 of the feeding turntable 22 is automatically started, or after the remaining tape rolls to be processed are manually placed on the feeding turntable 22, the user operates the control panel manually to turn it on.

[0042] In addition, as yet another improvement, a first reel motor speed regulator 7, a turntable motor speed regulator 8, and a second reel motor speed regulator 9, all electrically connected to the controller, are provided on the above-mentioned support platform 13 from top to bottom. The first reel motor speed regulator 7 can be used by an operator to adjust the rotational speeds of the reel motors of each unwinding reel 21 and each rewinding reel 31. The turntable motor speed regulator 8 can be used by an operator to adjust the rotational speeds of the unwinding motor 24 and the rewinding motor 34. The second reel motor speed regulator 9 can be used by an operator to adjust the rotational speeds of the reel motors of each separator paper reel 5. The controller can perform the matching of the above various controls according to the parameters related to rotational speed input through each speed regulator, and can, through manual setting, adapt to the conveyance and processing of the to-be-processed strip 20 with different parameters such as different ductility and different total lengths. It can also slow down the rotational speeds of the corresponding motors during the cutting operation and the transfer operation, thereby ensuring the reliable implementation of each operation. In addition, for the two situations where the probability that the remaining to-be-processed strip reels obtained after unwinding need to be simultaneously transferred to the unwinding turntable 22 or the processed strip reels need to be simultaneously cut and the cut heads of the two remaining processed strips 30 to be formed need to be simultaneously wound onto the rewinding turntable 32 is very low, before such situations occur, the first reel motor speed regulator 7 can be used to adjust the rotational speeds of the two unwinding reels 21 or the two rewinding reels 31 respectively, so as to stagger the moments when the two remaining to-be-processed strip reels on the two unwinding reels 21 need to be transferred and also stagger the moments when the processed strip reels on the two rewinding reels 31 need to be cut, thus preventing the occurrence of any one of the two situations with a very low probability.

[0043] As yet another improvement, multiple CCDs can be used to correspondingly replace each coil thickness detector, and the image recognition function of the CCDs can be used to detect the thicknesses of the above-mentioned to-be-processed strip reels, processed strip reels, and separator paper reels, so as to control the indicator to prompt corresponding information according to the results of each thickness detection.

[0044] As another object of the present invention, please refer to Figure 5 and in combination with Figures 1 to 4, an LED patch bracket injection molding device is provided, including: an LED patch bracket injection molding device 40 and any one of the above-mentioned LED patch bracket conveying devices 10. The LED patch bracket injection molding device can obtain the beneficial effects brought by any one of the LED patch bracket conveying devices 10, which will not be elaborated here. The LED patch bracket injection molding device 40 is provided with a processing position and is used to apply injection molding processing to the LED patch brackets on the section of the strip to be processed 20 located at the processing position. The LED patch bracket injection molding device 40 applies a traction force to the strip to be processed 20, specifically the feeding reel 21 or the feeding turntable 22 of the feeding mechanism 2, moving towards the processing position, and applies a pushing force to the processed strip 30, specifically the take-up reel 31 or the take-up turntable 32 of the take-up mechanism 3, moving from the processing position. Further, when the LED patch bracket injection molding device 40 needs to perform the initial processing at the processing position or after each processing, the strip to be processed 20 is applied with a traction force, causing the strip to be processed 20 to move away from the feeding sensor 23. Then, the feeding sensor 23 does not detect the strip to be processed 20, so the feeding motor 24 is controlled to start working. At the same time, the processed strip 30 is applied with a pushing force, causing the processed strip 30 to abut against the take-up sensor 33. Then, the take-up sensor 33 detects the processed strip 30, so the take-up motor 34 is controlled to start working. At this time, the driving force applied by the feeding turntable 22 and the traction force act together on the strip to be processed 20, and the driving force applied by the take-up turntable 32 and the pushing force act together on the processed strip 30 to convey the next length of the strip to be processed 20 to the processing position for processing. And when the LED patch bracket injection molding device 40 is performing processing at the processing position, it does not apply a traction force to the strip to be processed 20, causing the strip to be processed 20 to sag and contact the feeding sensor 23. Then, the feeding sensor 23 detects the strip to be processed 20, so the feeding motor 24 is controlled to stop working. At the same time, the processed strip 30 is not applied with a pushing force, causing the processed strip 30 to move away from the take-up sensor 33. Then, the take-up sensor 33 does not detect the processed strip 30, so the take-up motor 34 is controlled to stop working. This ensures that when the strip to be processed 20 is being processed, the strip to be processed 20 is not affected by the driving force and traction force applied by the feeding turntable 22, and the processed strip 30 is not affected by the driving force and pushing force applied by the take-up turntable 32. Thus, the strip to be processed 20 being processed will not be affected by other external forces except the processing force, ensuring the reliability of the processing quality. Therefore, the LED patch bracket injection molding device has the advantages of high production efficiency and good processing quality for the injection molding of LED patch brackets.
