Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a dispensing machine. Background Technology

[0002] To ensure a firm connection between the workpiece and the fixture, it is usually necessary to apply glue to the connection point between the workpiece and the fixture using a dispensing device. When the dispensing device is working, the workpiece to be glued is first placed on the transfer platform. Then, the robotic arm and the workpiece clamping platform move in coordination. After reaching the predetermined position, the dispensing gun starts to dispense glue. After the glue is dispensed, the dispensing gun is removed and the next workpiece is taken out.

[0003] Although the above-mentioned dispensing equipment can perform dispensing work, when the materials are applied after dispensing the materials to the fixture, lint or dust from the workshop and conveyor belt will adhere to the materials. When the materials are attached to the fixture, these dusty substances can easily affect the adhesiveness, leading to adhesive breakage in the later products. This reduces the product's lifespan and aesthetics, and fails to meet production needs and user requirements. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dispensing machine that solves the problems mentioned in the background section, such as dust, lint, and other substances easily adhering to the bottom of the adhesive during patch assembly, which can affect the adhesive properties of the product and cause problems like adhesive breakage and detachment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dispensing machine, comprising a material conveying device, a material handling device, and a fixture transport device, characterized in that:

[0006] The material conveying equipment includes a base, a vibrating plate, a support base, and a conveying track. The vibrating plate is installed on the top of the base, the support base is installed above the base, the top of the base and the support base are connected by a conveying track, and the material picking area is installed above the conveying track.

[0007] The transmission track includes a conveyor belt and a transmission support. The conveyor belt is equipped with sensing areas near the vibratory feeder and near the material picking area. A placement plate is provided in the sensing area near the material picking area. The side wall of the transmission support is equipped with a light sensor. Each sensing area corresponds to two light sensors. Each light sensor is equipped with an air jet on both the left and right sides. A mounting bracket is movably connected to the top of the transmission support.

[0008] The material handling equipment includes a mounting base, a rotating arm, a robotic arm, a mounting plate, a telescopic cylinder, and a suction cup. The rotating arm is movably connected to the top of the mounting base, and the robotic arm is mounted above the rotating arm. The mounting plate is movably connected to the lower part of the robotic arm, and the telescopic cylinder is mounted on the mounting plate. The telescopic cylinder is equipped with a suction cup.

[0009] The fixture transport equipment includes a transfer frame, a stop column, and a dispensing device. The stop column is installed inside the transfer frame, and the dispensing device is movably installed above the transfer frame.

[0010] Preferably, the mounting frame includes a lint roller, a rotating shaft, a main wheel, a linkage wheel, a secondary wheel, and a connecting rod. The lint roller is coaxially fixed to the rotating shaft, and the main wheel is installed at both the upper and lower ends of the rotating shaft. A linkage wheel is meshed with one side of the main wheel, and a secondary wheel is meshed with the side of the linkage wheel away from the main wheel. There are four sets of secondary wheels, and a connecting rod runs through the interior of the four sets of secondary wheels.

[0011] Preferably, the lint roller has a rotatable structure consisting of a secondary roller, a connecting roller, a main roller, and a rotating shaft.

[0012] Preferably, the placement plate includes a contact rod connected to its inner surface, a slide cylinder is provided below the contact rod, a contact is provided inside the slide cylinder, and a compression spring is sleeved on the outer wall of the slide cylinder. The placement plate forms an elastic structure with the contact rod, the compression spring, and the contact.

[0013] Preferably, the vibratory feeder is cylindrical, and the bottom wall of the vibratory feeder is tightly attached to the upper surface of the base, and the side wall of the vibratory feeder has a discharge port for connecting the transmission track.

[0014] Preferably, the length of the transmission track is between 5m and 8m, the width of the transmission track is between 30cm and 50cm, and the transmission track is covered with anti-slip rubber mats.

[0015] Preferably, the mounting base is equipped with a rotary motor, and the output end of the rotary motor is connected to the rotary arm.

[0016] Preferably, the robot arm is horizontally positioned above the rotating arm. The robot arm is equipped with a hydraulic cylinder, the output end of which is connected to a mounting plate. A telescopic cylinder is provided on one side of the mounting plate, and a rack plate is provided on the other side of the mounting plate.

[0017] Preferably, there are four sets of telescopic cylinders, and each of the four sets of telescopic cylinders has a suction cup at the bottom of its output end. The rotating arm forms a telescopic structure with the suction cups through the hydraulic cylinder and the telescopic cylinder.

[0018] Preferably, a fan is installed inside the conveyor support, and the fan is connected to the air jet through a ventilation pipe. The air jet angle is set at 15°.

[0019] This invention provides a dispensing machine with the following advantages:

[0020] This dispensing machine uses two photoelectric sensors to trigger the conveyor belt to stop and the robotic arm on the material handling device to start picking up the material. The second infrared sensor is located at the beginning of the track. When there are enough small heat sinks on the track, the second photoelectric sensor is triggered to stop the vibrator. This setting can prevent material from accumulating on the track and causing blockage, and can also reduce energy consumption.

[0021] The hydraulic cylinder drives the telescopic cylinder on the mounting plate to move downwards, and presses and picks up the small heat sink on the placement plate through the suction cup. At the same time, it squeezes the placement plate, and the placement plate moves downwards through the contact rod and the compression spring, so that the contact rod collides with the contact head and conducts electricity, which makes the built-in fan operate and blow air. The air is blown onto the small heat sink through the air jets on the upper and lower sides for dust removal. The air jets are set at an angle of 15°, so the air blown out is inclined from bottom to top, which can blow away the lint and dust from the small heat sink and the sensing area.

[0022] As the hydraulic cylinder drives the telescopic cylinder on the mounting plate to move downwards, the rack plate on the mounting plate also moves downwards, engaging with the auxiliary wheel to drive the linkage wheel, main wheel, and rotating shaft to rotate. This causes the lint roller to rotate, adhering impurities to the surface of the small heat sink to be attracted, achieving a pre-treatment adhesion effect. This further achieves the effects of dust removal and dust reduction, reducing impurities adhering to the small heat sink. This overcomes the problems of adhesive failure and glue breakage caused by dust adhering to the small heat sink in the prior art. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Please see Figures 1 to 9 The present invention provides a dispensing machine, including a material conveying device 1, a material picking device 2, and a fixture transport device 3. The material conveying device 1 includes a base 101, a vibratory feeder 102, a support base 103, and a transmission track 104. The vibratory feeder 102 is provided on the top of the base 101, the support base 103 is provided above the base 101, the transmission track 104 is connected to the top of the base 101 and the support base 103, and a material picking area is provided above the transmission track 104.

[0042] The transmission track 104 includes a conveyor belt 1041 and a transmission support 1042. The conveyor belt 1041 is provided with sensing areas near the vibratory feeder 102 and near the material picking area. A placement plate 105 is provided in the sensing area near the material picking area. A light sensor 1043 is provided on the side wall of the transmission support 1042. Each sensing area corresponds to two light sensors 1043. Air nozzles 1044 are provided on the left and right sides of each light sensor 1043. A mounting bracket 106 is movably connected to the top of the transmission support 1042.

[0043] The material handling device 2 includes a mounting base 201, a rotating arm 202, a robotic arm 203, a mounting plate 204, a telescopic cylinder 205, and a suction cup 206. The rotating arm 202 is movably connected to the top of the mounting base 201, and the robotic arm 203 is mounted above the rotating arm 202. The mounting plate 204 is movably connected to the lower part of the robotic arm 203. The telescopic cylinder 205 is mounted on the mounting plate 204, and the suction cup 206 is mounted on the telescopic cylinder 205.

[0044] The fixture transport equipment 3 includes a transfer frame 301, a stop post 302, and a dispensing device 303. The stop post 302 is installed inside the transfer frame 301, and the dispensing device 303 is movably installed above the transfer frame 301.

[0045] The small heat sinks vibrate onto the conveyor belt 1041 via the vibratory feeder 102. The conveyor belt 1041 has two sensing areas. The first photoelectric sensor 1043 is located at the end of the track and can trigger the conveyor belt 1041 to stop running and cause the robotic arm 203 on the material handling device 2 to start operating to grab the material. The second photoelectric sensor 1043 is located at the initial position of the track. When there are enough small heat sinks on the track, the second photoelectric sensor 1043 is triggered, causing the vibratory feeder 102 to stop vibrating. This setting can prevent material from accumulating on the track and causing blockage, and can also reduce energy consumption.

[0046] like Figure 5 As shown, in this embodiment, the mounting frame 106 includes a lint roller 1061, a rotating shaft 1062, a main wheel 1063, a linkage wheel 1064, a secondary wheel 1065, and a connecting rod 1066. The lint roller 1061 is coaxially fixed to the rotating shaft 1062. The main wheel 1063 is installed at both the upper and lower ends of the rotating shaft 1062. The linkage wheel 1064 is meshed with one side of the main wheel 1063. The secondary wheel 1065 is meshed with the side of the linkage wheel 1064 away from the main wheel 1063. There are four sets of secondary wheels 1065, and the connecting rod 1066 passes through the interior of the four sets of secondary wheels 1065.

[0047] The lint roller 1061 has a rotatable structure consisting of a secondary roller 1065, a linkage roller 1064, a main roller 1063, and a rotating shaft 1062.

[0048] When the conveyor belt 1041 stops operating, the robotic arm 203 operates to grab the small heat sink. At the same time, the hydraulic cylinder drives the telescopic cylinder 205 on the mounting plate 204 to move downward, and the rack plate 2041 on the mounting plate 204 also moves downward. This engages with the auxiliary wheel 1065, driving the linkage wheel 1064, the main wheel 1063 and the rotating shaft 1062 to rotate, which in turn drives the lint roller 1061 to rotate. This causes the impurities on the surface of the small heat sink to be picked up to adhere to it, achieving a pre-treatment adhesion effect. This can further achieve the effect of dust removal and dust reduction, reducing the amount of impurities adhering to the small heat sink. This overcomes the problem of adhesive failure and glue breakage caused by dust adhering to the small heat sink in the prior art.

[0049] The placement plate 105 includes a contact rod 1051 connected to its inner surface. A slide cylinder 1052 is provided below the contact rod 1051. A contact 1053 is provided inside the slide cylinder 1052. A compression spring 1054 is sleeved on the outer wall of the slide cylinder 1052. The placement plate 105 forms an elastic structure with the contact rod 1051, the compression spring 1054 and the contact 1053.

[0050] The hydraulic cylinder drives the telescopic cylinder 205 on the mounting plate 204 to move downwards, and presses and picks up the small heat sink on the placement plate 105 through the suction cup 206. At the same time, the placement plate 105 is squeezed. The placement plate 105 moves downwards through the contact rod 1051 and the compression spring 1054, so that the contact rod 1051 collides with the contact 1053 and is energized, causing the built-in fan to operate and blow air. The air is blown onto the small heat sink through the air jets 1044 on the upper and lower sides for dust removal. Since the air jets are set at a 15° angle, the blown air is tilted from bottom to top, which can blow away lint and dust from the periphery and bottom of the small heat sink and the sensing area.

[0051] The vibratory plate 102 is cylindrical, and the bottom wall of the vibratory plate 102 is tightly attached to the upper surface of the base 101. The side wall of the vibratory plate 102 is provided with a discharge port for connecting the transmission track 104.

[0052] The length of the transmission track 104 is between 5m and 8m, the width of the transmission track 104 is between 30cm and 50cm, and the transmission track 104 is covered with anti-slip rubber mats.

[0053] The mounting base 201 is equipped with a rotary motor, and the output end of the rotary motor is connected to the rotary arm 202.

[0054] The robotic arm 203 is horizontally positioned above the rotating arm 202. A hydraulic cylinder is installed inside the robotic arm 203. The output end of the hydraulic cylinder is connected to a mounting plate 204. A telescopic cylinder 205 is installed on one side of the mounting plate 204, and a rack plate 2041 is installed on the other side of the mounting plate 204.

[0055] The telescopic cylinder 205 is provided in four sets. The bottom of the output end of each of the four sets of telescopic cylinders 205 is provided with a suction cup 206. The rotating arm 202 forms a telescopic structure with the suction cup 206 through the hydraulic cylinder and the telescopic cylinder 205.

[0056] A fan is installed inside the conveyor support 1042. The fan is connected to the jet nozzle 1044 through a ventilation pipe. The jet nozzle 1044 has a jet angle of 15°.

[0057] The working principle of this dispensing machine is as follows: Small heat sinks vibrate onto the conveyor belt 1041 via a vibrating plate 102. The conveyor belt 1041 is equipped with two sensing areas. The first photoelectric sensor 1043 is located at the end of the track and can trigger the conveyor belt 1041 to stop running and cause the robotic arm 203 on the material handling device 2 to start operating to grab the material. The second photoelectric sensor 1043 is located at the initial position of the track. When there are enough small heat sinks on the track, the second photoelectric sensor 1043 is triggered, causing the vibrating plate 102 to stop vibrating. This setting can prevent material from accumulating on the track and causing blockage, and can also reduce energy consumption.

[0058] When the conveyor belt 1041 stops operating and the robotic arm 203 is triggered to grab the small heat sink, the hydraulic cylinder drives the telescopic cylinder 205 on the mounting plate 204 to move downwards over a long distance. Upon reaching the designated position, the telescopic cylinder 205 controls the suction cup 206 to press and pick up the small heat sink on the placement plate 105. Simultaneously, the rack plate 2041 on the mounting plate 204 moves downwards, meshing with the auxiliary wheel 1065 and driving the linkage wheel 1064, main wheel 1063, and rotating shaft 1062 to rotate. This, in turn, drives the lint roller 1061 to rotate, adhering impurities from the surface of the small heat sink to be picked up on the rear conveyor belt 1041, achieving a pre-treatment adhesion effect. This setup prevents dust from the conveyor belt 1041 from being brought into the sensing area, ensuring a smooth material handling process. Leaving a clean adsorption environment further reduces the adhesion of impurities to the small heat sink. While pressing, the placement plate 105 is squeezed, and the placement plate 105 moves downward through the contact rod 1051 and the compression spring 1054, so that the contact rod 1051 collides with the contact 1053 to conduct electricity, causing the built-in fan to operate and blow air. The air is blown onto the small heat sink through the air jets 1044 on the upper and lower sides of the conveying bracket 1042 for dust removal. Since the air jets are set at a 15° angle, the blown air is tilted from bottom to top, which can blow away lint and dust from the periphery, bottom and sensing area of ​​the small heat sink, further realizing the dust removal of the small heat sink. This application overcomes the problem of adhesive failure and adhesive breakage caused by dust sticking to the small heat sink in the background technology by using the dual dust removal effect of pretreatment adhesion suction and blowing dust removal.

[0059] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
