[0050] The present invention will be further described below with reference to the accompanying drawings.

[0051] An air conditioner, or air conditioner, is a small air conditioning unit consisting of four parts: a refrigeration (heating) circulation system, an air circulation and ventilation system, an electrical control system, and a housing. It maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space.

[0052] The assembly process of the air conditioner outdoor unit's electrical control system includes installing injection molded parts, installing radiators, applying silicone sheets, applying thermal paste, assembling radiators, fixing radiators, visual inspection, board assembly, fixing IPM components, fixing diode components, fixing IGBT components, and fixing the main board. According to the production process requirements, the electrical control production needs to be carried out under standard tooling positioning. Using tooling can not only support the components and prevent them from collapsing, but also accurately position the electrical box to meet automation requirements. Currently, the first process of installing injection molded parts relies on manual operation to place the injection molded parts into the tooling for positioning. Due to the irregular shape, complex shape, and easy deformation of the injection molded parts, as well as the difficulty in separating multiple injection molded parts, automated feeding has not been achieved, resulting in low work efficiency and assembly efficiency.

[0053] Example 1

[0054] To address the aforementioned technical issues, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model embodiment provides an automatic feeding device for injection molded parts, including:

[0055] Conveying assembly 10 is used to convey injection molded part 60;

[0056] The suction component 20 is located at the tail end of the conveying component 10;

[0057] The positioning detection component 30 is located at the tail end of the conveying component 10 and includes a positioning mold 310 and multiple deformation sensors 320 located at different positions within the positioning mold 310.

[0058] The suction component 20 is configured to suction the injection molded part 60 from the conveying component 10 and place the injection molded part 60 into the positioning mold 310. Multiple deformation sensors 320 are configured to detect whether the injection molded part 60 in the positioning mold 310 is deformed.

[0059] It should be noted that, as Figure 1 , Figure 2 As shown, the tail end of the conveying assembly 10 is the right end of the conveying assembly 10. The positioning detection assembly 30 is arranged opposite to the conveying assembly 10 (i.e., on the same axis). The suction assembly 20 is located behind the positioning detection assembly 30 so as to transfer the injection molded part 60 on the conveying assembly 10 to the positioning mold 310.

[0060] It should be noted that before using the deformation sensor 320 to detect the injection molded part 60 inside the positioning mold 310, point creation (i.e., setting standard detection signals) is required. This involves placing a qualified standard injection molded part 60 inside the positioning mold 310, ensuring the standard injection molded part 60 is placed flat, and touching the deformation sensors 320 at multiple locations inside the positioning mold 310. The deformation detection data of multiple deformation sensors 320 are recorded, and the deformation detection data is used as the basis for determining whether the injection molded part 60 is deformed. Then, the standard injection molded part 60 is removed from the positioning mold 310 for automated detection and loading. The deformation sensor 320 can be a fiber optic sensor.

[0061] In some embodiments, the conveying assembly 10 includes:

[0062] Belt conveyor mechanism 110;

[0063] Two side baffles 120 are arranged opposite each other on the belt conveyor mechanism 110, and their inlet ends are provided with outwardly inclined guide sections;

[0064] The feeding sensor 130 is located at the inlet end of the side baffle 120;

[0065] The belt conveyor mechanism 110 is configured to start conveying based on the feeding signal detected by the feeding sensor 130.

[0066] It should be noted that, as Figure 2 As shown, the belt conveyor mechanism 110 includes a conveyor motor, a transmission chain, a conveyor roller, and a belt line disposed on the conveyor roller. One end of the transmission chain is connected to the conveyor motor, and the other end of the transmission chain is connected to the conveyor roller. The belt line is driven to move by the conveyor motor and the transmission chain.

[0067] It should be noted that two shaped plates can be provided on both sides of the conveyor belt, and two side baffles 120 are installed on the two shaped plates respectively. The distance between the two side baffles 120 is adapted to the width of the injection molded part 60 to prevent the injection molded part 60 from shaking during the conveying process. The inlet end of the side baffle 120 is the right end of the side baffle 120. The guide section extends outward from the belt conveyor mechanism 110 to provide a large space at the inlet of the belt conveyor mechanism 110, which facilitates the placement of the injection molded part 60 on the belt conveyor mechanism 110. The loading sensor 130 can be a through-beam sensor. The loading sensor 130 can be set on the side baffle 120 or on the side of the belt conveyor mechanism 110. By setting the loading sensor 130, the belt conveyor mechanism 110 can stop working when no injection molded part 60 is placed, so as to reduce energy consumption. When loading is detected (i.e., the injection molded part 60 is placed on the belt conveyor mechanism 110), the operation is started.

[0068] In some embodiments, the automatic injection molding part feeding device further includes a primary positioning component 40, which includes:

[0069] A positioning sensor 410 is mounted on the side baffle 120;

[0070] A clamping cylinder 420 is located at the outlet end of the belt conveyor mechanism 110. The clamping cylinder 420 is configured to clamp the injection molded part 60 according to the primary positioning signal detected by the primary positioning sensor 410.

[0071] It should be noted that the primary positioning sensor 410 is located to the left of the feeding sensor 130. The primary positioning sensor 410 can be a through-beam sensor. The clamping cylinder 420 is connected to two clamping plates, which are located at the outlet end of the belt conveyor structure (located on the belt conveyor mechanism 110). After receiving the primary positioning signal, the clamping cylinder 420 drives the two clamping plates to clamp the injection molded part 60 and perform primary positioning on the injection molded part 60 so that the suction assembly 20 can easily suction the injection molded part 60.

[0072] In some embodiments, the automatic injection molding part feeding device further includes a separation component 50, which includes:

[0073] Separation sensor 550 is mounted on conveying assembly 10;

[0074] The separation bracket 510 is mounted on the belt conveyor mechanism 110 and is located in front of the clamping cylinder 420;

[0075] The lifting cylinder 520 has its cylinder barrel connected to the separation bracket 510;

[0076] The horizontal telescopic cylinder 530 is connected to the piston rod of the lifting cylinder 520;

[0077] The separator plate 540 is connected to the piston rod of the horizontal telescopic cylinder 530;

[0078] The lifting cylinder 520 is configured to extend its piston rod according to the separation signal detected by the separation sensor 550 to lower the horizontal telescopic cylinder 530 to a preset blocking height. The horizontal telescopic cylinder 530 is configured to extend its piston rod according to the separation signal to block the movement of the injection molded part 60 through the separation plate 540.

[0079] It should be noted that, as Figure 3 As shown, the separation bracket 510 includes a separation upper baffle 5101, and a separation left baffle 5102 and a separation right baffle 5103 connected to the separation upper baffle 5101. The separation left baffle 5102 and the separation right baffle 5103 are fixed on both sides of the belt conveyor mechanism 110 or on the strip plate. The cylinder of the lifting cylinder 520 is connected to the separation upper baffle 5101. The lower end face of the separation plate 540 is lower than the horizontal telescopic cylinder 530 so as to block the injection molded part 60. The size of the separation plate 540 can be adjusted according to the size of the injection molded part 60. The preset blocking height can be adjusted according to the actual situation. The separation sensor 550 can be a through-beam sensor. The separation sensor 550 can be set on the side of the belt conveyor mechanism 110 or on the side baffle 120.

[0080] In some embodiments, the separation assembly 50 further includes a cylinder connector, one side of which is connected to the piston rod of the lifting cylinder 520, and the other side of which is connected to the cylinder barrel of the horizontal telescopic cylinder 530.

[0081] It should be noted that the cylinder connector is plate-shaped and has a larger area than the piston rod, which facilitates connection with the horizontal telescopic cylinder 530 and improves the stability of the connection.

[0082] In some embodiments, the positioning detection component 30 further includes:

[0083] The positioning and detection bracket 330 is located at the tail end of the conveying component 10 and is higher than the preset detection height of the conveying component 10. The positioning mold 310 is provided on it.

[0084] A secondary positioning sensor 340 is located on the side of the positioning detection bracket 330 facing the conveying assembly 10;

[0085] The suction component 20 is configured to transfer the injection molded part 60 clamped by the clamping cylinder 420 into the positioning mold 310 based on the secondary positioning signal detected by the secondary positioning sensor 340.

[0086] It should be noted that, as Figure 1 , Figure 5 As shown, the positioning detection bracket 330 includes an outer support leg, a top panel, and a secondary positioning plate 3301. The outer support leg is supported on the ground. The secondary positioning plate 3301 is located on the tail end (or strip plate) of the belt conveyor mechanism 110. The positioning mold 310 is located on the top panel. The secondary positioning sensor 340 is located on the side of the secondary positioning plate 3301 facing the belt conveyor mechanism 110 and is used to detect whether the injection molded part 60 is in place. The secondary positioning sensor 340 is a fiber optic sensor.

[0087] In some embodiments, the aspiration component 20 includes:

[0088] Robotic arm 210;

[0089] The suction cup mechanism 220 is connected to the robotic arm 210 and is used to pick up the injection molded part 60.

[0090] In some embodiments, the suction cup mechanism 220 further includes a vacuum detection sensor for detecting the vacuum level of the suction cup mechanism 220.

[0091] It should be noted that the suction cup mechanism 220 can be easily moved by the robotic arm 210. The suction cup mechanism 220 typically includes a vacuum pump, a cylinder, multiple suction nozzles, ejector pins, and ejector pin support rods. By setting a vacuum detection sensor inside the suction cup mechanism 220, the vacuum level of the suction cup mechanism 220 can be easily detected to ensure that the injection molded part 60 can be adsorbed.

[0092] It should be noted that the automatic feeding device for injection molded parts in this embodiment of the present invention also includes a control system. The control system is connected to a primary positioning sensor 410, a secondary positioning sensor 340, a separation sensor 550, a clamping cylinder 420, a lifting cylinder 520, a horizontal telescopic cylinder 530, a robotic arm 210, and a suction cup mechanism 220. The control system is used to control the actuators to perform corresponding actions based on the signals detected by the sensors.

[0093] It should be noted that the working process of the automatic injection molding part feeding device provided in this embodiment of the utility model is as follows:

[0094] 1) Point creation: The moving robotic arm 210 picks up the injection molded part 60 and puts it into the positioning mold 310, ensuring that the injection molded part 60 is placed horizontally and that the four corners of the injection molded part 60 touch the fiber optic sensor at the bottom of the positioning mold 310. The amplifier value in the fiber optic sensor is recorded and used as the basis for determining whether the injection molded part 60 is deformed. The moving robotic arm 210 makes the suction cup assembly pick up the injection molded part 60 and fit it into the product installation fixture, and then saves the point data.

[0095] 2) Setting up the separation component 50: Adjust the spacing of the separation plate 540 according to the size specifications of the injection molded part 60, adjust it through the control system, and test it;

[0096] 3) Sensor installation and calibration: Install the through-beam sensors (feeding sensor 130, primary positioning sensor 410, secondary positioning sensor 340, separation sensor 550, etc.) for detection at the predetermined positions, connect them to the control system, and perform sensor calibration and sensitivity adjustment so that they can accurately feed back the detected information to the control system to realize the automated operation of the separation component 50 and the conveying component 10.

[0097] 4) Start work: Manually place the injection molded part 60 onto the conveyor belt;

[0098] 5) When the feeding sensor 130 detects the injection molded part 60 and provides feedback, the belt conveyor mechanism 110 starts to rotate and convey the injection molded part 60. When the injection molded part 60 reaches the position of the positioning mold 310, the primary positioning sensor 410 senses the primary positioning signal, and the clamping cylinder 420 works to perform a primary positioning of the injection molded part 60 to ensure the success rate of the suction component 20. When the separation sensor 550 detects the separation signal, the lifting cylinder 520 extends the piston rod to lower the horizontal telescopic cylinder 530 to the preset blocking height. The horizontal telescopic cylinder 530 extends the piston rod to block the injection molded part 60 behind from moving forward through the separation plate 540.

[0099] 6) After the injection molded part 60 is placed in the positioning mold 310, the deformation sensor 320 at the bottom of the positioning mold 310 detects the placement position of the injection molded part 60 and makes a judgment based on the amplifier value. At the same time, the separation component 50 works to raise the separation plate 540 so that the injection molded part 60 behind can pass through and stop in front of the positioning mold 310 to wait to be picked up.

[0100] (1) When the injection molded part 60 cannot be completely placed in the mold, or the amplifier value exceeds the set value range, it is determined that the deformation of the injection molded part 60 does not meet the production requirements, and the part is ejected and the equipment alarm is triggered.

[0101] (2) When the injection part 60 can be placed into the mold normally and the amplifier value is within the set value range, a return signal is sent to the suction component 20;

[0102] 7) Upon receiving the signal, the suction component 20 suctions the injection molded part 60 and simultaneously performs vacuum detection;

[0103] (1) The vacuum detection of the suction cup assembly is set to 10 grids. When the vacuum detection result reaches 7 grids or more, it is considered qualified. The qualified suction assembly 20 places the injection molded part 60 on the tooling plate and proceeds to the next process.

[0104] (2) If the vacuum test fails, an alarm will be issued and a manual inspection will be conducted to determine if the injection molded part is reversed at 60°.

[0105] 8) The suction component 20 places the injection molded part 60 into the product mounting fixture, and then suctions the next injection molded part 60.

[0106] In summary, this embodiment of the utility model, by setting up the suction component 20, can suction the injection molded part 60 on the conveying component 10 and place the injection molded part 60 into the positioning mold 310; by setting multiple deformation sensors 320 at different positions in the positioning mold 310, it can detect whether the injection molded part 60 in the positioning mold 310 is deformed. This can solve the problem that currently, when assembling the injection molded part 60, the injection molded part 60 is manually placed into the mold for positioning, and because the injection molded part 60 has a complex shape, it is impossible for humans to identify whether the injection molded part 60 has been deformed, resulting in a low assembly qualification rate and low work efficiency. This improves the assembly qualification rate and work efficiency of the injection molded part 60.

The deformation detection data of multiple deformation sensors 320 are recorded, and the deformation detection data is used as the basis for determining whether the injection molded part 60 is deformed. Then, the standard injection molded part 60 is removed from the positioning mold 310 for automated detection and loading. The deformation sensor 320 can be a fiber optic sensor.

One end of the transmission chain is connected to the conveyor motor, and the other end of the transmission chain is connected to the conveyor roller. The belt line is driven to move by the conveyor motor and the transmission chain.

[0121] It should be noted that two shaped plates can be provided on both sides of the conveyor belt, and two side baffles 120 are installed on the two shaped plates respectively. The distance between the two side baffles 120 is adapted to the width of the injection molded part 60 to prevent the injection molded part 60 from shaking during the conveying process. The inlet end of the side baffle 120 is the right end of the side baffle 120.

[0125] It should be noted that the primary positioning sensor 410 is located to the left of the feeding sensor 130. The primary positioning sensor 410 can be a through-beam sensor. The clamping cylinder 420 is connected to two clamping plates, which are located at the outlet end of the belt conveyor structure (located on the belt conveyor mechanism 110).

The size of the separation plate 540 can be adjusted according to the size of the injection molded part 60. The preset blocking height can be adjusted according to the actual situation. The separation sensor 550 can be a through-beam sensor. The separation sensor 550 can be set on the side of the belt conveyor mechanism 110 or on the side baffle 120.

[0134] In some embodiments, the separation assembly 50 further includes a cylinder connector, one side of which is connected to the piston rod of the lifting cylinder 520, and the other side of which is connected to the cylinder barrel of the horizontal telescopic cylinder 530.

[0135] It should be noted that the cylinder connector is plate-shaped and has a larger area than the piston rod, which facilitates connection with the horizontal telescopic cylinder 530 and improves the stability of the connection.

[0136] In some embodiments, the positioning detection component 30 further includes:

[0137] The positioning and detection bracket 330 is located at the tail end of the conveying component 10 and is higher than the preset detection height of the conveying component 10. The positioning mold 310 is provided on it.

[0138] A secondary positioning sensor 340 is located on the side of the positioning detection bracket 330 facing the conveying assembly 10;

[0139] The suction component 20 is configured to transfer the injection molded part 60 clamped by the clamping cylinder 420 into the positioning mold 310 based on the secondary positioning signal detected by the secondary positioning sensor 340.

[0140] It should be noted that, as Figure 1 , Figure 5As shown, the positioning detection bracket 330 includes an outer support leg, a top panel, and a secondary positioning plate 3301. The outer support leg is supported on the ground. The secondary positioning plate 3301 is located on the tail end (or strip plate) of the belt conveyor mechanism 110. The positioning mold 310 is located on the top panel. The secondary positioning sensor 340 is located on the side of the secondary positioning plate 3301 facing the belt conveyor mechanism 110 and is used to detect whether the injection molded part 60 is in place. The secondary positioning sensor 340 is a fiber optic sensor.

[0141] In some embodiments, the aspiration component 20 includes:

[0142] Robotic arm 210;

[0143] The suction cup mechanism 220 is connected to the robotic arm 210 and is used to pick up the injection molded part 60.

[0144] In some embodiments, the suction cup mechanism 220 further includes a vacuum detection sensor for detecting the vacuum level of the suction cup mechanism 220.

[0145] It should be noted that the suction cup mechanism 220 can be easily moved by the robotic arm 210. The suction cup mechanism 220 typically includes a vacuum pump, a cylinder, multiple suction nozzles, ejector pins, and ejector pin support rods. By setting a vacuum detection sensor inside the suction cup mechanism 220, the vacuum level of the suction cup mechanism 220 can be easily detected to ensure that the injection molded part 60 can be adsorbed.

[0146] In some embodiments, the plurality of deformation sensors 320 are four deformation sensors 320, which are located at the four corners of the positioning mold 310.

[0147] It should be noted that four deformation sensors 320 are set at the four corners of the positioning mold 310 to detect whether the injection molded part 60 has deformed. When deformation of the injection molded part 60 is detected, the defective injection molded part 60 can be removed from the positioning mold 310 by the adsorption component. When no deformation of the injection molded part 60 is detected, the qualified injection molded part 60 can be moved to the product mounting fixture by the adsorption component for the next assembly step. A vision inspection device can be set on the suction component 20 to determine whether the injection molded part 60 is placed in place, which has higher accuracy.

[0148] It should be noted that the automatic feeding device for injection molded parts in this embodiment of the present invention also includes a control system. The control system is connected to a primary positioning sensor 410, a secondary positioning sensor 340, a separation sensor 550, a clamping cylinder 420, a lifting cylinder 520, a horizontal telescopic cylinder 530, a robotic arm 210, and a suction cup mechanism 220. The control system is used to control the actuators to perform corresponding actions based on the signals detected by the sensors.

[0149] It should be noted that the working process of the automatic injection molding part feeding device provided in this embodiment of the utility model is as follows:

[0150] 1) Point creation: The moving robotic arm 210 picks up the injection molded part 60 and puts it into the positioning mold 310, ensuring that the injection molded part 60 is placed horizontally and that the four corners of the injection molded part 60 touch the fiber optic sensor at the bottom of the positioning mold 310. The amplifier value in the fiber optic sensor is recorded and used as the basis for determining whether the injection molded part 60 is deformed. The moving robotic arm 210 makes the suction cup assembly pick up the injection molded part 60 and fit it into the product installation fixture, and then saves the point data.

[0151] 2) Setting up the separation component 50: Adjust the spacing of the separation plate 540 according to the size specifications of the injection molded part 60, adjust it through the control system, and test it;

[0152] 3) Sensor installation and calibration: Install the through-beam sensors (feeding sensor 130, primary positioning sensor 410, secondary positioning sensor 340, separation sensor 550, etc.) for detection at the predetermined positions, connect them to the control system, and perform sensor calibration and sensitivity adjustment so that they can accurately feed back the detected information to the control system to realize the automated operation of the separation component 50 and the conveying component 10.

[0153] 4) Start work: Manually place the injection molded part 60 onto the conveyor belt;

[0154] 5) When the feeding sensor 130 detects the injection molded part 60 and provides feedback, the belt conveyor mechanism 110 starts to rotate and convey the injection molded part 60. When the injection molded part 60 reaches the position of the positioning mold 310, the primary positioning sensor 410 senses the primary positioning signal, and the clamping cylinder 420 works to perform a primary positioning of the injection molded part 60 to ensure the success rate of the suction component 20. When the separation sensor 550 detects the separation signal, the lifting cylinder 520 extends the piston rod to lower the horizontal telescopic cylinder 530 to the preset blocking height. The horizontal telescopic cylinder 530 extends the piston rod to block the injection molded part 60 behind from moving forward through the separation plate 540.

[0155] 6) After the injection molded part 60 is placed in the positioning mold 310, the deformation sensor 320 at the bottom of the positioning mold 310 detects the placement position of the injection molded part 60 and makes a judgment based on the amplifier value. At the same time, the separation component 50 works to raise the separation plate 540 so that the injection molded part 60 behind can pass through and stop in front of the positioning mold 310 to wait to be picked up.

[0156] (1) When the injection molded part 60 cannot be completely placed in the mold, or the amplifier value exceeds the set value range, it is determined that the deformation of the injection molded part 60 does not meet the production requirements, and the part is ejected and the equipment alarm is triggered.

[0157] (2) When the injection part 60 can be placed into the mold normally and the amplifier value is within the set value range, a return signal is sent to the suction component 20;

[0158] 7) Upon receiving the signal, the suction component 20 suctions the injection molded part 60 and simultaneously performs vacuum detection;

[0159] (1) The vacuum detection of the suction cup assembly is set to 10 grids. When the vacuum detection result reaches 7 grids or more, it is considered qualified. The qualified suction assembly 20 places the injection molded part 60 on the tooling plate and proceeds to the next process.

[0160] (2) If the vacuum test fails, an alarm will be issued and a manual inspection will be conducted to determine if the injection molded part is reversed at 60°.

[0161] 8) The suction component 20 places the injection molded part 60 into the product mounting fixture, and then suctions the next injection molded part 60.

[0162] In summary, this embodiment of the utility model, by setting up the suction component 20, can suction the injection molded part 60 on the conveying component 10 and place the injection molded part 60 into the positioning mold 310; by setting multiple deformation sensors 320 at different positions in the positioning mold 310, it can detect whether the injection molded part 60 in the positioning mold 310 is deformed. This can solve the problem that currently, when assembling the injection molded part 60, the injection molded part 60 is manually placed into the mold for positioning, and because the injection molded part 60 has a complex shape, it is impossible for humans to identify whether the injection molded part 60 has been deformed, resulting in a low assembly qualification rate and low work efficiency. This improves the assembly qualification rate and work efficiency of the injection molded part 60.

[0163] Example 3

[0164] To address the aforementioned technical issues, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model embodiment provides an automatic feeding device for injection molded parts, including:

[0165] Conveying assembly 10 is used to convey injection molded part 60;

[0166] The suction component 20 is located at the tail end of the conveying component 10;

[0167] The positioning detection component 30 is located at the tail end of the conveying component 10 and includes a positioning mold 310 and multiple deformation sensors 320 located at different positions within the positioning mold 310.

[0168] The suction component 20 is configured to suction the injection molded part 60 from the conveying component 10 and place the injection molded part 60 into the positioning mold 310. Multiple deformation sensors 320 are configured to detect whether the injection molded part 60 in the positioning mold 310 is deformed.

[0169] It should be noted that, as Figure 1 , Figure 2 As shown, the tail end of the conveying assembly 10 is the right end of the conveying assembly 10. The positioning detection assembly 30 is arranged opposite to the conveying assembly 10 (i.e., on the same axis). The suction assembly 20 is located behind the positioning detection assembly 30 so as to transfer the injection molded part 60 on the conveying assembly 10 to the positioning mold 310.

[0170] It should be noted that before using the deformation sensor 320 to detect the injection molded part 60 inside the positioning mold 310, point creation (i.e., setting standard detection signals) is required. This involves placing a qualified standard injection molded part 60 inside the positioning mold 310, ensuring the standard injection molded part 60 is placed flat, and touching the deformation sensors 320 at multiple locations inside the positioning mold 310. The deformation detection data of multiple deformation sensors 320 are recorded, and the deformation detection data is used as the basis for determining whether the injection molded part 60 is deformed. Then, the standard injection molded part 60 is removed from the positioning mold 310 for automated detection and loading. The deformation sensor 320 can be a fiber optic sensor.

[0171] In some embodiments, the conveying assembly 10 includes:

[0172] Belt conveyor mechanism 110;

[0173] Two side baffles 120 are arranged opposite each other on the belt conveyor mechanism 110, and their inlet ends are provided with outwardly inclined guide sections;

[0174] The feeding sensor 130 is located at the inlet end of the side baffle 120;

[0175] The belt conveyor mechanism 110 is configured to start conveying based on the feeding signal detected by the feeding sensor 130.

[0176] It should be noted that, as Figure 2 As shown, the belt conveyor mechanism 110 includes a conveyor motor, a transmission chain, a conveyor roller, and a belt line disposed on the conveyor roller. One end of the transmission chain is connected to the conveyor motor, and the other end of the transmission chain is connected to the conveyor roller. The belt line is driven to move by the conveyor motor and the transmission chain.

[0177] It should be noted that two shaped plates can be provided on both sides of the conveyor belt, and two side baffles 120 are installed on the two shaped plates respectively. The distance between the two side baffles 120 is adapted to the width of the injection molded part 60 to prevent the injection molded part 60 from shaking during the conveying process. The inlet end of the side baffle 120 is the right end of the side baffle 120. The guide section extends outward from the belt conveyor mechanism 110 to provide a large space at the inlet of the belt conveyor mechanism 110, which facilitates the placement of the injection molded part 60 on the belt conveyor mechanism 110. The loading sensor 130 can be a through-beam sensor. The loading sensor 130 can be set on the side baffle 120 or on the side of the belt conveyor mechanism 110. By setting the loading sensor 130, the belt conveyor mechanism 110 can stop working when no injection molded part 60 is placed, so as to reduce energy consumption. When loading is detected (i.e., the injection molded part 60 is placed on the belt conveyor mechanism 110), the operation is started.

[0178] In some embodiments, the automatic injection molding part feeding device further includes a primary positioning component 40, which includes:

[0179] A positioning sensor 410 is mounted on the side baffle 120;

[0180] A clamping cylinder 420 is located at the outlet end of the belt conveyor mechanism 110. The clamping cylinder 420 is configured to clamp the injection molded part 60 according to the primary positioning signal detected by the primary positioning sensor 410.

[0181] It should be noted that the primary positioning sensor 410 is located to the left of the feeding sensor 130. The primary positioning sensor 410 can be a through-beam sensor. The clamping cylinder 420 is connected to two clamping plates, which are located at the outlet end of the belt conveyor structure (located on the belt conveyor mechanism 110). After receiving the primary positioning signal, the clamping cylinder 420 drives the two clamping plates to clamp the injection molded part 60 and perform primary positioning on the injection molded part 60 so that the suction assembly 20 can easily suction the injection molded part 60.

[0182] In some embodiments, the automatic injection molding part feeding device further includes a separation component 50, which includes:

[0183] Separation sensor 550 is mounted on conveying assembly 10;

[0184] The separation bracket 510 is mounted on the belt conveyor mechanism 110 and is located in front of the clamping cylinder 420;

[0188] The lifting cylinder 520 is configured to extend its piston rod according to the separation signal detected by the separation sensor 550 to lower the horizontal telescopic cylinder 530 to a preset blocking height. The horizontal telescopic cylinder 530 is configured to extend its piston rod according to the separation signal to block the movement of the injection molded part 60 through the separation plate 540.

[0189] It should be noted that, as Figure 3 As shown, the separation bracket 510 includes a separation upper baffle 5101, and a separation left baffle 5102 and a separation right baffle 5103 connected to the separation upper baffle 5101. The separation left baffle 5102 and the separation right baffle 5103 are fixed on both sides of the belt conveyor mechanism 110 or on the strip plate. The cylinder of the lifting cylinder 520 is connected to the separation upper baffle 5101. The lower end face of the separation plate 540 is lower than the horizontal telescopic cylinder 530 so as to block the injection molded part 60. The size of the separation plate 540 can be adjusted according to the size of the injection molded part 60. The preset blocking height can be adjusted according to the actual situation. The separation sensor 550 can be a through-beam sensor. The separation sensor 550 can be set on the side of the belt conveyor mechanism 110 or on the side baffle 120.

[0190] In some embodiments, the separation assembly 50 further includes a cylinder connector, one side of which is connected to the piston rod of the lifting cylinder 520, and the other side of which is connected to the cylinder barrel of the horizontal telescopic cylinder 530.

[0191] It should be noted that the cylinder connector is plate-shaped and has a larger area than the piston rod, which facilitates connection with the horizontal telescopic cylinder 530 and improves the stability of the connection.

[0192] In some embodiments, the positioning detection component 30 further includes:

[0193] The positioning and detection bracket 330 is located at the tail end of the conveying component 10 and is higher than the preset detection height of the conveying component 10. The positioning mold 310 is provided on it.
