Description

Technical Field

[0001] The present invention relates to the field of caulking equipment, and in particular to an automatic caulking equipment for lamp caps of lamp tubes. Background Art

[0002] During the assembly process of LED lamp tubes, the assembly of their lamp caps often adopts connection methods such as screw fixation and snap fixation, and corresponding sealing strips are configured to achieve the functions of waterproofing and dustproofing. The assembly structure is relatively auxiliary and the processes are numerous.

[0003] In order to simplify the assembly process of LED lamp tubes, there is currently a method of directly using glue to assemble the lamp caps, which simultaneously realizes the fixation and sealing functions of the lamp caps. During assembly, it is necessary to first apply glue to the lamp caps and then assemble and fix them with the lamp tube body. In order to improve the glue application efficiency of the lamp caps, automatic glue applicators for lamp caps are widely used. For example, the existing document (I) with the application number CN201721767753.0 - A lamp cap glue applicator for an LED lamp tube. However, although the above - mentioned existing document (I) can achieve automatic glue application, it mainly transfers the lamp caps to the glue - applying mechanism by rotating the turntable, and then the tooling components on the turntable rotate to cooperate with the glue - applying mechanism to complete the glue application. At this time, during the rotation of the turntable and the tooling components, the position of the lamp core may shift due to mechanical vibration, thus affecting the glue application effect.

[0014] The feeding mechanism is a vibrating plate feeder.

[0015] Furthermore, the dial driving mechanism includes a rotating motor, a driving gear fixedly mounted on the output shaft of the rotating motor, and a transmission gear meshing with the driving gear; the transmission gear is coaxially arranged and fixedly connected to the second dial; the output shaft of the rotating motor is coaxially arranged and fixedly connected to the first dial.

[0016] Furthermore, the glue discharging mechanism further comprises a glue discharging head driving mechanism; the glue discharging port of the glue discharging head faces the tray; the glue discharging head driving mechanism is used for driving the glue discharging head to reciprocate along its length direction.

[0030] As Figures 1-6 shown, an automatic glue dispensing device for lamp holders of a lamp tube includes

[0031] Feeding mechanism 10; the feeding mechanism 10 is used to feed the lamp holder 70 to be sealed with glue. Specifically, the feeding mechanism 10 is a vibrating disk feeder, which can continuously and evenly feed the lamp holder 70 and enable the glue-sealing surface of the lamp holder 70 to face upward. The structure of this vibrating disk feeder can be a machine that can be directly purchased on the market, or it can refer to the structure of the feeding and material selection mechanism in the existing literature with the publication number CN210252910U.

[0032] Workbench 20; an unloading station is formed on the workbench 20. Specifically, the loading station is formed on the upper surface of the workbench 20. The workbench 20 is connected to the feeding mechanism 10 to allow the lamp holder 70 fed by the feeding mechanism 10 to enter the loading station. Specifically, the workbench 20 is connected to the discharge port of the vibrating disk feeder. The previously fed lamp holder 70 can be transferred to the loading station under the multiple pushes of the subsequently fed lamp holders 70.

[0033] Tray 30; the tray 30 is used to hold the lamp holder 70. Specifically, through holes can be drilled through the workbench 20, and the tray 30 is rotatably placed in the through holes, and the upper surface of the tray 30 is flush with the upper surface of the work platform.

[0034] Tray rotation driving mechanism 40; the tray rotation driving mechanism 40 is used to drive the tray 30 to rotate around the central axis of the tray 30.

[0035] Glue discharging mechanism 50; the glue discharging mechanism 50 includes a glue discharging head 51. The glue discharging port of the glue discharging head 51 can be aligned with the edge of the lamp holder 70 located on the tray 30. At this time, the glue discharging head 51 of the glue discharging mechanism 50 discharges glue, and the tray 30 rotates, so that a circle of glue can be dotted on the lamp holder 70 to complete the glue dotting operation.

[0036] The material dialing machine 60; the first dial 61 and the second dial 62 are spaced apart to form an inlet and outlet channel for the lamp holder 70 to enter and exit; the feeding station, the tray 30 and the discharging station are all located in the inlet and outlet channel; the side of the first dial 61 is provided with a plurality of first toggle grooves 611 arranged in sequence around its circumference; the side of the second dial 62 is provided with a plurality of second toggle grooves 621 arranged in sequence around its circumference; the first toggle grooves 611 and the second toggle grooves 621 can both be used for the lamp holder 70 to be inserted; the dial driving mechanism 63 is used to drive the first dial 61 and the second dial 62 to rotate synchronously in opposite directions, so that any one of the first toggle grooves 611 and any one of the second toggle grooves 621 cooperate to toggle the lamp holder 70 of the feeding station to the tray 30. It can be understood that the first toggle groove 611 and the second toggle groove 621 can be used to drive the first dial 61 and the second dial 62 to rotate synchronously in opposite directions. The groove 611 and the second toggle groove 621 to toggle the lamp head 70 is actually the groove wall of the first toggle groove 611 and the groove wall of the second toggle groove 621 to toggle the lamp head 70. At this time, the groove wall of the first toggle groove 611 and the groove wall of the second toggle groove 621 can reduce the possibility of vibration deviation of the lamp head 70, and improve the stability of its transfer process; furthermore, the first toggle groove 611 and the second toggle groove 621 that cooperate with each other can also position the lamp head 70 on the tray 30. At this time, the groove wall of the first toggle groove 611 and the groove wall of the second toggle groove 621 are respectively movably fitted with the outer side surface of the lamp head 70, thereby avoiding the possibility of the lamp head 70 being deflected due to mechanical vibration during the gluing process, that is, during the rotation of the tray 30, and improving the stability of the gluing; thereby, ensuring the accuracy of gluing.

[0037] Preferably, when the lamp holder 70 is located on the tray 30 , the groove wall of the first toggle groove 611 matches and fits with the outer side surface of the lamp holder 70 , and the groove wall of the second toggle groove 621 matches and fits with the outer side surface of the lamp holder 70 , thereby achieving positioning of the lamp holder 70 .

[0038] The above-mentioned dial driving mechanism 63 can adopt a structure in which two motors cooperate, and the two motors drive the first dial 61 and the second dial 62 respectively. However, this structure consumes a lot of energy and needs to control the synchronous start and shutdown of the two motors, which is difficult. The present invention provides a preferred embodiment: the dial driving mechanism 63 includes a rotating motor 631, a driving gear 632 fixedly sleeved on the output shaft of the rotating motor 631, and a transmission gear 633 meshed with the driving gear 632; the transmission gear 633 is coaxially arranged and fixedly connected with the second dial 62; the output shaft of the rotating motor 631 is coaxially arranged and fixedly connected with the first dial 61, so that the rotating motor 631 rotates, and the first dial 61 is driven to rotate through the output shaft of the rotating motor 631, and the output shaft of the rotating motor 631 drives the second dial 62 to rotate through the driving gear 632 and the driven gear, so that the two rotate synchronously, reduce energy loss, and are convenient to operate. At the same time, the driving gear 632 and the driven gear can cooperate to stably transmit the power of the rotating motor 631, so that the transmission of the first dial gear is more stable.

[0039] Specifically, the glue dispensing mechanism 50 also includes a glue dispensing head driving mechanism 52; the glue outlet of the glue dispensing head 51 faces the tray 30; the glue dispensing head driving mechanism 52 is used to drive the glue dispensing head 51 to reciprocate along its length direction, so that the glue outlet is close to the lamp head 70 to ensure the accuracy of glue dispensing, or the glue outlet is away from the lamp head 70 to avoid the glue dispensing head 51 from hindering the rotation of the first dial 61 and the second dial 62.

[0040] Preferably, the glue dispensing head 51 is arranged at an angle.

[0041] Furthermore, the glue dispensing head driving mechanism 52 includes a slide cylinder, the telescopic rod of the cylinder is transmission-connected to the glue dispensing head 51, and the slide of the slide cylinder can be installed on an external wall or bracket, so that the driving of the glue dispensing point driving mechanism is more stable; of course, the glue dispensing head driving mechanism 52 can also use a linear motor, etc.

[0042] Furthermore, a discharging station is formed on the workbench 20 and is located in the entry and exit channel; the feeding station, the tray 30 and the discharging station are arranged in sequence; the first toggle groove 611 and the second toggle groove 621 can also cooperate to toggle the lamp head 70 of the tray 30 to the discharging station, completing the discharging after dispensing, thereby improving the automated operation.

[0043] Furthermore, the automatic gluing equipment for lamp tube lamp holders also includes a controller and a first detector; the first detection device is used to detect whether there is a lamp holder 70 at the discharging station, and sends a signal to the controller when the lamp holder 70 is detected; when the controller receives the signal, it stops the operation of the dial driving mechanism 63, that is, as long as there is a lamp holder 70 at the discharging station, the dial driving mechanism 63 is in a closed state to avoid accidentally ejecting the lamp holder 70 at the discharging station, causing the lamp holder 70 to fall from the workbench 20.

[0044] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
