Description

Technical Field

[0001] The invention relates to the field of lamp glue dispensing, and in particular to a glue dispensing machine. Background Art

[0002] LED long strip lamps mainly include long strip lamp aluminum base, long strip lamp lens, lampshade, LED lamp board and mounting end cap. In the assembly process of LED long strip lamps, a special glue dispensing process is required to fix some parts. The existing long strip lamp glue dispensing needs to be done manually with the help of specific clamps. The manual fixation method with the help of clamps is often done by workers relying on experience to operate and position. Not only is the pass rate worrying, but the production efficiency is also relatively low. In addition, manual glue dispensing will cause the glue dispensing process to be inconsistent with the next process. At the same time, different types of clamps will take up a lot of storage space, which is very inconvenient.

[0003] For this purpose, the Chinese utility model patent with patent number CN201620090319.2 discloses a "lamp tube dispensing assembly machine", which includes a frame, a pressing mechanism, a light bar combination moving mechanism, a dispensing robot and a dispensing device. The light bar combination moving mechanism, the dispensing robot and the pressing mechanism are arranged on the frame in sequence, and the dispensing device is arranged on the dispensing robot. During dispensing, the assembly machine places the lamp tube on the lamp tube fixture, and then places the light bar on the light bar placement block. Through the cooperation of the dispensing robot and the dispensing device, the glue is applied to the lamp tube, and then the pressing mechanism is pressed down to achieve a quick and smooth combination of the lamp tube and the light bar. Although the assembly machine can achieve the dispensing of the light bar, it still has certain defects:

[0004] 1. The dispensing robot can only move up and down and move horizontally and vertically in the plane. It cannot deflect the dispensing robot, and the dispensing of glue at some corners is not in place;

[0005] 2. Due to the long size of the long strip lamp, loading and unloading is very inconvenient and the efficiency is low. Improper operation can easily cause the long strip lamp shell to deform;

[0006] 3. The lamp tube fixtures are still of fixed size and cannot be adjusted according to the size of the lamp, so the compatibility is low. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a glue dispensing machine which can automatically load and unload materials and will not damage the lamp housing in view of the current status of the above-mentioned prior art.

[0008] The second technical problem to be solved by the present invention is to provide a glue dispensing machine which can adapt to different types of lamp housings and has good compatibility.

[0009] The third technical problem to be solved by the present invention is to provide a glue dispensing machine which is flexible in dispensing glue and leaves no dead angles.

[0010] The technical solution adopted by the present invention to solve the above first technical problem is as follows: A dispensing machine includes a fuselage, and further includes:

[0011] A feeding mechanism for transporting the lamp housing to be dispensed to the fuselage and horizontally arranged on one side of the fuselage;

[0012] A positioning and clamping mechanism is arranged on the fuselage and is located downstream of the feeding mechanism. The positioning and clamping mechanism has a chuck for clamping the lamp housing to be dispensed;

[0013] A dispensing head is arranged on the fuselage and has a dispensing valve that can move freely relative to the fuselage to dispense glue to the lamp housing to be dispensed on the positioning and clamping mechanism;

[0014] A discharging mechanism for transporting the lamp housing after dispensing away from the fuselage. The discharging mechanism is horizontally arranged on the other side opposite to the feeding mechanism and is located downstream of the positioning and clamping mechanism;

[0015] A material transfer mechanism is arranged in the middle of the fuselage and can move back and forth between the feeding mechanism and the discharging mechanism to move the lamp housing to be dispensed on the feeding mechanism to the positioning and clamping mechanism and move the lamp housing after dispensing on the positioning and clamping mechanism to the discharging mechanism. The material transfer mechanism has a transfer platform that reciprocally slides along the longitudinal direction of the fuselage.

[0016] In order to ensure that the long strip-shaped lamp housing can be smoothly transported without affecting the loading and unloading due to its excessive length, both the feeding mechanism and the discharging mechanism are provided with two material transporting modules for transporting the same lamp housing. The two material transporting modules are arranged at intervals and extend in the same direction. An avoidance gap for the movement of the material transfer mechanism is formed between the two material transporting modules.

[0017] The technical solution adopted by the present invention to solve the above second technical problem is as follows: The material transporting module includes two support plates and a first driving mechanism. The two support plates are both horizontally arranged on the fuselage and are arranged side by side. Driven by the first driving mechanism, the two support plates can approach each other to clamp the lamp housing to be dispensed or move away from each other to release the lamp housing after dispensing, so as to ensure that the material transporting module can adapt to lamp housings of different width dimensions.

[0018] In order to drive the movement of the two support plates, the first driving mechanism includes a threaded rod for driving the two support plates to approach each other or move away from each other and a width-adjusting motor for driving the threaded rod to rotate. The threaded rod is arranged on the two support plates, and the output shaft of the width-adjusting motor is connected to the threaded rod.

[0019] In order to enable the threaded rod to drive the two support plates to approach each other or move away from each other simultaneously, two threaded portions with opposite spiral directions are provided on the outer peripheral wall of the threaded rod, and the two threaded portions are respectively threadedly connected to their corresponding support plates.

[0020] To ensure the smooth conveyance of the housing during loading and unloading, a feeding channel for transporting the lamp housing is formed by the gap between the two support plates. Moreover, conveyor belts are respectively arranged on the two support plates, and a second driving mechanism for driving the rotation of the conveyor belts is also arranged on the machine body. The two conveyor belts are respectively arranged on the opposite inner side walls of the feeding channel, and both conveyor belts are connected to their corresponding support plates through transmission components.

[0021] To ensure that the second driving mechanism can drive the conveyor belts, rotating shafts penetrate longitudinally through the two support plates. The transmission component includes a driving wheel and a driven wheel. The driving wheel is coaxially arranged with the rotating shaft and is arranged on the inner side wall of the feeding channel. The head end and the tail end of each support plate are provided with the driven wheels, and each conveyor belt is wound around the driven wheel and the driving wheel of its corresponding support plate.

[0022] Specifically for driving, the second driving mechanism includes a driving motor, a first transmission wheel, and a second transmission wheel. The first transmission wheel is connected to the output end of the driving motor. The second transmission wheel is coaxially arranged with the rotating shaft and is arranged on the outer side wall of the feeding channel. The first transmission wheel and the second transmission wheel are linked by a belt or a chain.

[0023] The technical solution adopted by the present invention to solve the above third technical problem is as follows: The dispensing head end includes a first slide rail horizontally arranged on the machine body, a second slide rail vertically arranged on the machine body, and a dispensing mechanism. The second slide rail is arranged on the first slide rail and can reciprocally slide horizontally under the drive of a third driving mechanism. The dispensing mechanism is arranged on the second slide rail and can reciprocally slide vertically under the drive of a fourth driving mechanism.

[0024] To realize the free movement of the dispensing head end, the dispensing mechanism includes a first lifting assembly, a rotating assembly, and a dispensing valve, where:

[0025] The first lifting assembly includes a first fixing plate, a first lifting plate, and a first driver. The first fixing plate is connected to the second slide rail. The first lifting plate is connected to the first fixing plate and can move up and down relative to the first fixing plate under the drive of the first driver;

[0026] The rotating assembly includes a rotating seat, a connecting member, and a second driver. The rotating seat is fixed to the lower part of the first lifting plate. The dispensing valve is fixedly connected to the connecting member. The output end of the second driver is drivingly connected to the connecting member. Under the drive of the fourth driving mechanism, the dispensing valve and the connecting member rotate synchronously relative to the rotating seat.

[0027] To ensure firm clamping of the entire long strip lamp housing, the positioning and clamping mechanism includes a fixing member and a first clamping member. The fixing member is horizontally arranged on the machine body, and there are multiple first clamping members which are spaced along the length direction of the fixing member.

[0028] To achieve clamping, specifically, the first clamping member includes a base for fixing on the fixing member and the pneumatic gripper. Two chucks are slidably arranged on both sides of the upper end of the base. A first clamping groove for clamping the lamp housing to be dispensed is formed between the two chucks. Under the action of the pneumatic gripper, the two chucks can approach or move away from each other to change the width of the first clamping groove, thereby clamping or releasing the lamp housing to be dispensed.

[0029] To ensure the smooth transfer and clamping of the lamp housing before dispensing and the smooth discharging after dispensing, the material transfer mechanism includes a transfer platform, a second lifting assembly, and a sliding assembly. Among them,

[0030] The second lifting assembly includes a second fixing plate, a second lifting plate, and a third driver for driving the second lifting plate to move up and down. The upper end of the second lifting plate is connected to the bottom end of the transfer platform, and under the drive of the third driver, the transfer platform can move up and down synchronously with the lifting plate relative to the machine body.

[0031] The sliding assembly includes a third slide rail, a slider connected to the bottom of the second fixing plate, and a fourth driver. The third slide rail is arranged on the machine body and is longitudinally arranged. The slider can drive the second fixing plate, the second lifting plate, and the transfer platform to slide reciprocally relative to the third slide rail under the drive of the fourth driver.

[0032] To ensure that loading and unloading can be carried out simultaneously and improve the transportation efficiency, a second clamping member is arranged on the transfer platform. There are two second clamping members which are arranged on the front and rear sides in the sliding direction of the transfer platform.

[0033] Specifically, the second clamping member includes a base for fixing on the transfer platform and a clamping cylinder. Two clamping arms connected to the output end of the clamping cylinder are slidably arranged on the front and rear sides of the upper end of the base. A second clamping groove for clamping the lamp housing to be dispensed is formed between the two clamping arms. In the state of the material transfer mechanism loading or unloading to the positioning and clamping mechanism, the first clamping groove and the second clamping groove are communicated with each other and form a containing space for a single lamp housing to be dispensed to be placed therein.

[0034] To ensure the supply of the glue during dispensing, a storage bin is also arranged on the machine body. The discharge end of the storage bin is provided with a glue supply pump for feeding the glue to the dispensing head.

[0035] In order to ensure the real-time judgment of whether the dispensing is qualified after dispensing, a weighing component is further arranged on the machine body. The weighing component includes a first weighing sensor for weighing the lamp housing before dispensing and a second weighing sensor for weighing the lamp housing after dispensing. The first weighing sensor is arranged between the feeding mechanism and the positioning and clamping mechanism, and the second weighing sensor is arranged between the positioning and clamping mechanism and the discharging mechanism.

[0036] Compared with the prior art, the advantages of the present invention are as follows: in this dispensing machine, the feeding mechanism can transport the lamp housing before dispensing to the machine body, the discharging mechanism can transport the lamp housing after dispensing away from the machine body and convey it to the next process, saving the time of manual handling. The material transfer mechanism can move back and forth between the feeding mechanism and the discharging mechanism. The setting of the transfer platform can ensure that the lamp housing is lifted from the middle of the whole lamp housing, so that it will not deform during movement. In addition, the setting of the chuck in the positioning and clamping mechanism can ensure the fixation of the lamp housing transferred to the positioning and clamping mechanism, and ensure that the lamp housing will not move during the dispensing process.

The first transmission wheel 262 and the second transmission wheel 263 are linked by a belt or a chain. During feeding or discharging, the left and right side edges of the lamp housing are respectively pressed on the conveyor belts 23 on the two support plates 21 to realize feeding and discharging.

[0053] See Figure 5 and Figure 6, in this embodiment, the dispensing head 6 is provided on the fuselage 1 and has a dispensing valve 633 that can move freely relative to the fuselage 1 to dispense glue to the lamp housing to be dispensed on the positioning and clamping mechanism 3; in order to facilitate dispensing at different angles, the free movement of the dispensing valve 633 includes lateral movement, longitudinal movement, up and down lifting, and deflection of the dispensing angle relative to the fuselage 1. Specifically, the dispensing head 6 includes a first slide rail 61 horizontally arranged on the fuselage 1, a second slide rail 62 longitudinally arranged on the fuselage 1, and a dispensing mechanism 63.

Under the drive of the fourth drive mechanism 65, the dispensing valve 633 and the connecting member 6322 rotate synchronously relative to the rotating seat 6321. Due to the action of the above structure, the dispensing valve 433 can move horizontally, longitudinally, up and down, and deflect the dispensing angle relative to the fuselage 1.

Two clamping heads 323 are slidably arranged on both sides of the upper end of the base 321. A first clamping groove 3a for clamping the lamp housing to be dispensed is formed between the two clamping heads 323. Under the action of the pneumatic gripper 322, the two clamping heads 323 can approach or move away from each other to change the width of the first clamping groove 3a, thereby clamping or releasing the lamp housing to be dispensed.

[0055] See Figure 8 and Figure 9, in this embodiment, the material transfer mechanism 5 is arranged in the middle of the fuselage 1 and can move back and forth between the feeding mechanism 2 and the discharging mechanism 4.

A second clamping groove 5a for clamping the lamp housing to be dispensed is formed between the two clamping arms 543. In the state where the material transfer mechanism 5 feeds or discharges materials to or from the positioning and clamping mechanism 3, the first clamping groove 3a and the second clamping groove 5a are communicated with each other and form a placing space for a single lamp housing to be dispensed to be placed therein.
