Description

Technical Field

[0001] The present application relates to the technical field of motor assembly, and in particular to an automatic motor assembly and dispensing production line. Background Art

[0002] Automatic motor assembly refers to the process of using automated equipment and technology to accurately and quickly assemble the various components of a motor to form a complete motor product. This process not only improves production efficiency and product quality, but also reduces labor costs and the risk of human errors. The dispensing operation in automatic motor assembly is one of the links in the motor manufacturing process. It involves accurately applying glue to specific parts of the motor to achieve the bonding, sealing or fixation of components. Motor assembly dispensing usually requires dispensing during the assembly of the motor base, motor end shell or motor stator winding. For motor assembly, dispensing is an indispensable and important step in the motor assembly process.

[0003] For example, the patent with authorization announcement number CN219436817U discloses a motor rotor bearing assembly and glue dispensing integrated machine, including a support table, a rotor storage rack, a gantry robotic arm, a bearing feeding device, a pressing device, and a glue dispensing and moving device. The bearing feeding device, the pressing device, and the glue dispensing and moving device are arranged in sequence, and the bearing feeding device and the glue dispensing and moving device are connected with the pressing device. The rotor bearing can be assembled and glued fully automatically, which saves labor costs and improves the degree of automation of the production line.

[0004] Although the above device realizes the automatic assembly of the motor including the dispensing step, since the motor is a commonly used electrical component, it is usually produced in large quantities. In addition, since the use scenarios of the motor are different, the shell shape and internal structure of the motor also change with its application scenario and model. Usually, the same model of motor is assembled and produced on an automatic assembly line to meet normal production needs.

[0005] When large quantities of orders for motors of different models come in, in order to meet production requirements, the same production line needs to produce other motors of different models. However, due to the change in motor model, its outer shell and internal structure are changed, and the parts of the motor that need to be glued during assembly also change accordingly. For example, the glue holes on the motor end cover that need to be glued have different depths depending on the motor model. Since the glue dispensing machine on the motor automatic assembly line usually only produces one model of motor, the glue dispensing part is a fixed position and cannot meet the assembly glue dispensing of motors of different models. Therefore, it is necessary to provide a motor automatic assembly glue dispensing production line to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] Embodiment 1: This embodiment mainly describes the basic structure and working principle of the motor automatic assembly dispensing production line, specifically:

[0035] like Figure 1-Figure 2 As shown, the present application provides a motor automatic assembly and dispensing production line, including a base 1, which is a support part of the motor automatic assembly and dispensing production line, and is composed of a plurality of steel frame support tables placed on the ground. The base 1 provides a stable support for the motor automatic assembly and dispensing, ensuring the normal progress of the motor automatic assembly and dispensing;

[0036] A conveyor belt 2 is fixedly installed on the base 1. The conveyor belt 2 runs through the base 1. The conveyor belt 2 is a conventional conveyor belt. Its purpose is to transfer the motor parts 3 placed on the conveyor belt 2 from one end of the conveyor belt 2 to the other end of the conveyor belt 2. However, during the conveying process, the motor parts 3 are subjected to processes such as dispensing, pressing, and assembly, thereby realizing the automatic assembly of the motor. Figure 1 As shown, at least two groups of motor parts 3 are placed on the conveyor belt 2. In this embodiment, the motor parts 3 can be parts such as motor end covers and motor housings, and the surfaces thereof are provided with glue dispensing holes for dispensing. After the glue dispensing holes are glued, the motor parts 3 need to be pressed together with other parts of the motor, thereby completing one of the steps of motor assembly;

[0037] Continue to refer Figure 1 ,by Figure 1 For example, the viewing angle is from left to right, and the end on the left side of the conveyor belt 2 is defined as the input end, and the end on the right side of the conveyor belt 2 is defined as the output end. From the input end to the output end, it will pass through the dispensing component 4, the pressing component 5 and the detection component 6 in sequence. The dispensing component 4, the pressing component 5 and the detection component 6 are all fixedly installed on the base 1. It can be understood that the motor part 3 will go through the three steps of dispensing, pressing and detection in sequence when it reaches the conveyor belt 2, thereby completing one of the important links of the motor assembly. The specific method of dispensing the motor assembly is described below;

[0038] like Figure 3-Figure 4 As shown, the dispensing assembly 4 includes a first bracket 41 fixedly mounted on the base 1, a first cylinder 42 is fixedly mounted on one side of the first bracket 41, the output end of the first cylinder 42 corresponds to the surface of the conveyor belt 2, and a bottom plate 43 is fixedly mounted on the output end of the first cylinder 42. It can be understood that when the first cylinder 42 is started, the output end of the first cylinder 42 drives the bottom plate 43 to move toward the surface of the conveyor belt 2. In this embodiment, when the output end of the first cylinder 42 is extended to the limit position, the distance between the bottom plate 43 and the surface of the conveyor belt 2 is small. At this time, when the motor part 3 is transported from the input end, due to the limitation of the bottom plate 43, the subsequent motor part 3 cannot continue to move toward the output end.

[0039] A second cylinder 44 is fixedly mounted on the bottom plate 43, and the output end of the second cylinder 44 is away from the first bracket 41. At the same time, a rear limit plate 45 is fixedly mounted on the output end of the second cylinder 44. When the second cylinder 44 is started, the rear limit plate 45 moves in a direction away from the first bracket 41, and is mainly used to limit one end of the motor part 3.

[0040] A second bracket 46 is fixedly mounted on the side of the base 1, and a third cylinder 47 is fixedly mounted on the second bracket 46. At the same time, a notch is opened on the side of the conveyor belt 2, and the output end of the third cylinder 47 corresponds to the notch. A side limit plate 48 is installed on the output end of the third cylinder 47. When the third cylinder 47 is started, the output end of the third cylinder 47 drives the side limit plate 48 to move toward the conveyor belt 2, and can pass through the notch to approach the surface of the conveyor belt 2, and its purpose is mainly to limit one side of the motor part 3;

[0041] Continue to refer Figure 4 A third bracket 49 is fixedly mounted on the base 1, and a fourth cylinder 410 is fixedly mounted on one side of the third bracket 49. The third bracket 49 is arranged on the side of the first bracket 41 on the conveyor belt 2 away from the input end. At the same time, the output end of the fourth cylinder 410 corresponds to the surface of the conveyor belt 2, and a front limit plate 411 is fixedly mounted on the output end of the fourth cylinder 410. When the fourth cylinder 410 is started, its output end drives the front limit plate 411 to move toward the surface of the conveyor belt 2, which is mainly used to limit the other end of the motor part 3, and its function is similar to that of the rear limit plate 45;

[0042] In this embodiment, the area between the front limit plate 411, the rear limit plate 45 and the side limit plate 48 is defined as the glue dispensing area. When the motor parts 3 are transported to the glue dispensing area via the conveyor belt 2, the conveyor belt 2 can be controlled to pause at this time. The glue dispensing of the motor parts 3 in the stagnant state is more stable. Then, the first cylinder 42 can be controlled to start and drive the bottom plate 43 to move downward, and then the second cylinder 44 can be started to control the rear limit plate 45 to move forward, and the motor parts 3 are pushed toward the output end position. At the same time, the conveyor belt 2 is paused, and the subsequent motor parts 3 are paused synchronously to avoid the subsequent motor parts 3 from piling up on one side of the bottom plate 43 during the glue dispensing process, which is inconvenient for subsequent glue dispensing one by one.

[0043] Then, the third cylinder 47 and the fourth cylinder 410 can be started at the same time to control the movement of the side limit plate 48 and the front limit plate 411 to limit the side and the other end of the motor part 3 respectively. At this time, the front and rear sides and the side of the motor part 3 are all limited by the limit plates, and the other side thereof is supported on the side of the conveyor belt 2. In this way, the motor part 3 is limited from four directions, and the positioning of the motor part 3 is completed, so as to facilitate the dispensing of the motor part 3;

[0044] It should be noted that, since the stroke of each motor is fixed, the motor part 3 is positioned at the same position each time, and the size of the motor part 3 does not change, thereby meeting the requirements for dispensing assembly of motors of the same model;

[0045] After the motor part 3 is positioned, the motor part 3 needs to be glued. Figure 4 As shown, a fourth bracket 412 is fixedly mounted on the base 1, and the fourth bracket 412 is arranged at the glue dispensing area. A fifth cylinder 413 is fixedly mounted on one side of the fourth bracket 412, and the output end of the fifth cylinder 413 corresponds to the surface of the conveyor belt 2. A glue dispenser 414 is fixedly mounted on the output end of the fifth cylinder 413. The glue dispenser 414 consists of a glue dispensing plate fixedly mounted on the output end of the fifth cylinder 413, and a glue dispensing cylinder fixedly mounted on one side of the glue dispensing plate. At least two groups of glue cylinders 7 are mounted on the glue dispensing cylinder. The glue cylinder 7 contains a glue for dispensing the motor parts 3, and a glue dispensing valve is arranged at the bottom of the glue cylinder 7 to facilitate the outflow of the glue. The glue dispensing valve is usually a solenoid valve, which is opened or closed by electronic control. At the same time, one end of the glue cylinder 7 passes through the glue dispensing cylinder and is connected to a glue dispensing tube 71, and the glue dispensing tube 71 is used for conveying and outflowing the glue.

[0046] In order to ensure that the glue dispenser 414 remains stable after being driven by the fifth cylinder 413, a bottom support plate (not shown in the figure) is fixedly installed at the bottom of the fourth bracket 412. When the fifth cylinder 413 drives the glue dispenser 414 to move downward, the glue dispenser plate will eventually overlap the bottom support plate, and this position is the final position of the glue dispenser 414 after moving downward. Since the stroke of the fifth cylinder 413 is fixed, the glue dispenser 414 will stay at this position each time glue is dispensed.

[0047] Continue to refer Figure 4 A dispensing head is arranged on the side of the dispensing tube 71 away from the glue cylinder 7. When the dispensing plate moves down and contacts the bottom support plate, the dispensing head also moves to the dispensing hole of the motor part 3. Then the dispensing valve can be opened, and the colloid flows from the glue cylinder 7 to the dispensing tube 71, and then is injected into the dispensing hole through the dispensing head to complete the dispensing.

[0048] In this embodiment, a PLC control system is provided in the base 1 to facilitate the alternating opening and closing of each electrical component;

[0049] In the above process, the positioning and dispensing of the motor part 3 are realized. However, when assembling and dispensing motors of different models, since the stroke of the dispenser 414 is fixed, when the thickness of the motor part 3 and the depth of its dispensing hole change, the dispenser 414 cannot adaptively dispense glue at the corresponding position. In order to solve this problem, Figure 4-Figure 6 As shown, first of all, unlike the above-mentioned prior art, the glue cartridge 7 is usually fixedly installed in the glue dispensing cylinder body, and the glue dispensing operation can be satisfied by simply adding glue to the glue cartridge 7 without disassembly. In the following, the connection mode between the glue cartridge 7 and the glue dispensing cylinder body is modified to a sliding connection, such as Figure 6 In the embodiment, a slide groove 417 is provided in the dispensing cylinder body, and the number and position of the slide grooves 417 correspond to the number and position of the rubber cylinder 7. At the same time, a first electromagnetic block 72 is fixedly installed on the side of the rubber cylinder 7, and the first electromagnetic block 72 is slidably installed in the slide groove 417. In the initial state, due to the action of gravity, the first electromagnetic block 72 is located at the bottom of the slide groove 417. At this time, the rubber cylinder 7 cannot continue to move downward. When subjected to external force, the rubber cylinder 7 is suitable for sliding upward. Through the cooperation of the first electromagnetic block 72 and the slide groove 417, it can be ensured that the rubber cylinder 7 keeps sliding in the same direction as the slide groove 417 when sliding, so as to avoid the rubber cylinder 7 from deviating during the up and down sliding process, thereby changing the position of the dispensing head and affecting the glue dispensing position;

[0050] When it is necessary to dispense glue to motor parts 3 of different models, if the depth of the dispensing hole of motor parts 3 of different models is shallower than that of the dispensing hole of motor parts 3 of the same model in the past, the fifth cylinder 413 drives the dispensing device 414 to move downward, and when the dispensing plate of the dispensing device 414 has not yet contacted the bottom support plate, the dispensing head has moved to the bottom of the dispensing hole, and then the fifth cylinder 413 continues to move, but because the motor part 3 is in a stationary state, at this time, under the action of the fifth cylinder 413, the glue cylinder 7 will slide upward relative to the motor part 3, and the first electromagnetic block 72 will slide in the slide groove 417 until the dispensing plate contacts the bottom support plate, and finally the dispensing head remains in the dispensing hole, and the upward sliding distance of the glue cylinder 7 changes accordingly according to the depth of the dispensing hole;

[0051] If the depth of the glue dispensing hole of the motor part 3 of a different model is deeper than that of the glue dispensing hole of the motor part 3 of the same model in the past, after the fifth cylinder 413 drives the glue dispensing device 414 to move downward, the glue dispensing head cannot reach the bottom of the glue dispensing hole. At this time, there may be a situation 1: the glue dispensing head is in the glue dispensing hole but does not contact the bottom of the glue dispensing hole. In this case, glue dispensing can be performed normally. Situation 2: the glue dispensing head is outside the glue dispensing hole, and there may be a situation where glue dispensing is not in place. In order to avoid the occurrence of situation 2, in the initial state, the size of the glue dispensing tube 71 can be set to be longer. When the fifth cylinder 413 drives the glue dispensing device 414 to move to the corresponding position, the glue dispensing head fits the surface of the conveyor belt 2. In this way, even if the motor part 3 is thinner and its glue dispensing hole is farther away from the glue dispensing cylinder, the glue dispensing head can still move to the bottom position in the glue dispensing hole to adapt to glue dispensing holes of different depths.

[0052] At the same time, in this embodiment, if the depths of the glue dispensing holes on the surface of the motor parts 3 are different, the glue cylinders 7 corresponding to the glue dispensing holes can follow the depths of the glue dispensing holes and eventually stay at different heights. In this way, each group of glue cylinders 7 can adapt to a variety of glue dispensing holes of different depths, thereby meeting the glue dispensing component production of motors of different models.

[0053] Embodiment 2: The above embodiment satisfies the dispensing holes of different depths by slidingly setting the glue cylinder 7. However, no matter when dispensing the glue to the deeper or shallower dispensing holes, the dispensing head will be at the bottom position in the dispensing hole for dispensing. In this way, the surface of the dispensing tube 71 near the dispensing head will inevitably be covered with colloid. After dispensing the glue to multiple groups of motor parts 3, the dispensing head will inevitably be blocked due to the accumulation of colloid.

[0054] In order to solve this problem, this embodiment adds structures such as a spring pin 8 and a limiting groove 9 on the basis of the above embodiment. Specifically:

[0055] like Figure 4-Figure 6As shown, a vertical slide bar 415 is fixedly installed on the fourth bracket 412, and a slider 416 is slidably installed on the surface of the slide bar 415. At the same time, the slider 416 is fixedly connected to the glue dispenser 414. When the fifth cylinder 413 drives the glue dispenser 414 to move downward, the slider 416 slides on the slide bar 415, so that the up and down movement of the glue dispenser 414 is further limited, making it more stable when moving. At the same time, a spring 13 is fixedly installed between the output end of the fifth cylinder 413 and the glue dispenser 414. When the glue dispenser 414 is restricted and cannot continue to move, the spring 13 absorbs the stroke force of the fifth cylinder 413.

[0056] like Figure 6 , Figure 8 As shown, a limiting groove 9 is provided on the side of the slider 416 away from the glue dispenser 414, and a spring pin 8 used in conjunction with the limiting groove 9 is movably mounted on the fourth bracket 412. It should be noted that the spring pin 8 cannot move up and down but can swing left and right;

[0057] The limiting groove 9 includes a first channel 91 opened on the slider 416. The first channel 91 is a vertical channel, which is divided into a first end close to the dispensing plate and a second end away from the dispensing plate. In the initial state, one end of the spring pin 8 is abutted at the first end position. For the convenience of description, the end of the spring pin 8 in contact with the limiting groove 9 is defined as the abutting end 81, and the position of the abutting end 81 on the first end is defined as the initial position. It should be noted that the abutting end 81 of the spring pin 8 is in a compressed state when it is abutted in the limiting groove 9.

[0058] A second channel 92 is provided at the second end of the first channel 91. The second channel 92 is composed of an inclined channel and a vertical channel, wherein the inclined channel is communicated with the first channel 91, and the vertical channel is communicated with the inclined channel. The groove bottom height of the first channel 91 is higher than the groove bottom height of the second channel 92 and forms a blocking step. Therefore, after the abutting end 81 enters the second channel 92 from the first channel 91, it cannot return to the first channel 91 from the second channel 92. For the convenience of explanation, the position where the first channel 91 and the second channel 92 are connected is defined as a first stationary point 94.

[0059] Continue to refer Figure 8 The end of the second channel 92 is connected to a third channel 93, and the end of the third channel 93 is connected to the first channel 91. The bottom height of the third channel 93 is lower than the bottom height of the second channel 92, and a blocking step is also formed. Therefore, after the abutting end 81 enters the third channel 93 from the second channel 92, it cannot return to the second channel 92 from the third channel 93.

[0060] It should be noted that a transition slope 96 is provided at the end of the third channel 93, and the highest position of the transition slope 96 is higher than the bottom height of the first channel 91 and forms a transition step, so that when the abutting end 81 slides in the first channel 91, it will not directly enter the third channel 93 due to the presence of the transition step;

[0061] In order to make the dispensing head enter the dispensing hole, the position of the dispensing head can be further adjusted, such as Figure 8 As shown, a lifting block 97 is provided at a position near the second channel 92 in the third channel 93. In the present application, the lifting block 97 is lifted or lowered by electric control. In the initial state, the lifting block 97 is in a lifted state, and its top protrudes from the third channel 93. The abutting end 81 cannot go over the lifting block 97 and continue to slide in the third channel 93. When the lifting block 97 is controlled to be closed, it will continue to descend, and the top of the lifting block 97 will be level with the bottom of the groove of the third channel 93. At this time, the abutting end 81 can continue to slide in the third channel 93. For the convenience of explanation, the end position of the lifting block 97 and the second channel 92 is defined as a second stationary point 95.

[0062] like Figure 6 As shown, at least two groups of second electromagnetic blocks 418 are fixedly installed in the glue dispenser 414, and the second electromagnetic blocks 418 are located on one side of the slide groove 417. The position and number of the second electromagnetic blocks 418 correspond to the position and number of the first electromagnetic blocks 72. It should be noted that the first electromagnetic block 72 and the second electromagnetic block 418 are existing electromagnetic lock structures. When the first electromagnetic block 72 and the second electromagnetic block 418 are energized, the two attract each other. Under the action of magnetic attraction, the first electromagnetic block 72 constantly approaches the second electromagnetic block 418 and fits more tightly with the slide groove 417, thereby increasing the friction between them. At this time, only by the gravity of the rubber cylinder 7 itself, the first electromagnetic block 72 can no longer continue to slide on the slide groove 417;

[0063] When performing the dispensing operation, the same as the above-mentioned dispensing link is that after positioning the motor part 3, the PLC control system controls the fifth cylinder 413 to start, and the fifth cylinder 413 drives the dispensing device 414 to move downward, and multiple groups of dispensing heads move into the dispensing holes. Due to the different depths of the dispensing holes, the first electromagnetic block 72 will eventually slide to different height positions in the slide groove 417. After the output end of the fifth cylinder 413 extends to the limit position, the PLC control system can control the first electromagnetic block 72 and the second electromagnetic block 418 to attract each other. Due to the magnetic attraction, the friction between the first electromagnetic block 72 and the slide groove 417 increases. If the dispensing device 414 moves up and down at this time, the glue cylinder 7 will also move up and down and drive the dispensing head to move synchronously;

[0064] When the glue dispenser 414 moves downward, the slider 416 moves downward synchronously, and the limit slot 9 also moves downward synchronously. The spring pin 8 in contact with the limit slot 9 slides in the first channel 91. When the glue dispenser 414 moves to the specified position driven by the fifth cylinder 413, the abutting end 81 moves from the initial position to the first stationary point 94. For details, please refer to Figure 8 At the same time, the spring 13 is also in a compressed state, see Figure 6 ;

[0065] Then the PLC control system can control the fifth cylinder 413 to close, and its output end retracts. The retraction of the output end of the fifth cylinder 413 drives the glue dispenser 414 to move up. Since the first electromagnetic block 72 and the second electromagnetic block 418 are in a state of attraction, the glue cylinder 7 moves up synchronously with the glue dispenser 414, and the glue dispensing heads located in each glue dispensing hole move up synchronously and are separated from the bottom of the glue dispensing hole.

[0066] When the glue dispenser 414 moves upward, the slider 416 moves upward synchronously and drives the limit slot 9 to move upward. The abutting end 81 enters the second channel 92 from the first stationary point 94 and reaches the second stationary point 95 through the second channel 92. Due to the restriction of the lifting block 97, the abutting end 81 cannot continue to slide, but because the stroke of the fifth cylinder 413 is fixed, the output end of the fifth cylinder 413 continues to retract, and at this time, the tension of the fifth cylinder 413 is absorbed by the spring 13, and the spring 13 changes from a compressed state to a stretched state. When the fifth cylinder 413 returns to its initial state, the spring 13 is stretched, but because the abutting end 81 is restricted, the slider 416 and the glue dispenser 414 are also restricted, and the glue dispensing head stays in the glue dispensing hole;

[0067] It can be understood that, during the above operation, the distance between the abutting end 81 moving from the first stationary point 94 to the second stationary point 95 is the distance the dispensing head moves up. In this embodiment, the distance between the first stationary point 94 and the second stationary point 95 is usually less than the hole depth of the dispensing hole, so as to avoid the dispensing head moving outside the dispensing hole when retreating, resulting in the subsequent dispensing not being in place.

[0068] Then the PLC control system controls the dispensing valve to open, and dispensing begins at this time. The amount of dispensing is usually preset by the PLC control system. After the dispensing is completed, the PLC control system can control the lifting block 97 to move downward, and then the abutting end 81 can continue to slide in the third channel 93. Finally, due to the rebound force of the spring 13, the abutting end 81 passes through the transition slope 96 from the third channel 93 to the initial position of the first channel 91, and the slider 416 returns to the initial position, while driving the dispensing device 414 back to the initial position, so as to facilitate the dispensing of the next group of motor parts 3;

[0069] During the dispensing process, the dispensing head will first reach the bottom of the dispensing hole, and then its position will be locked by the first electromagnetic block 72 and the second electromagnetic block 418. After locking, the dispensing device 414 will move up a certain distance and then dispense glue. In this way, the dispensing head is separated from the bottom of the dispensing hole, avoiding the colloid from being contaminated on the dispensing head and causing blockage of the dispensing head, thereby improving the quality of motor assembly dispensing.

[0070] Embodiment 3: In the above process, through the cooperation of the spring pin 8 and the limit groove 9 and other components, after the dispensing head reaches the specified position, it will move up a certain distance and then dispense glue. When dispensing glue, there is a certain distance between the dispensing head and the bottom of the dispensing hole. If some motor parts 3 need to be filled with glue in the hole, no matter how much the dispensing head moves up, the surface of the dispensing head will still be contaminated with colloid;

[0071] To solve this problem, Figure 6-Figure 7 As shown, at least two groups of columns 10 are fixedly installed on the side of the conveyor belt 2, and a pick plate 11 is fixedly installed on the column 10. In this embodiment, at least two groups of through holes are opened on the pick plate 11. The number and position of the through holes correspond to the number and position of the dispensing tube 71. When the dispensing tube 71 moves down, it is suitable for passing through the through hole. At the same time, the aperture size of the through hole is adapted to the diameter size of the dispensing tube 71. When the dispensing tube 71 passes through the through hole, if the surface of the dispensing tube 71 is coated with colloid, since the aperture size of the through hole is adapted to the diameter size of the dispensing tube 71, the colloid cannot pass through the through hole synchronously with the dispensing tube 71, and the colloid will be separated from the dispensing tube 71 and retained on the pick plate 11.

[0072] Continue to refer Figure 8 A guide pad 12 for guiding the colloid is fixedly installed on the pick plate 11. The number and position of the guide pad 12 correspond to the number and position of the through holes. The guide pad 12 is a bell-shaped setting. The diameter of the end away from the surface of the pick plate 11 is smaller and matches the diameter of the through hole. The diameter of the end close to the pick plate 11 is larger so that the colloid can flow along. In this way, the colloid picked out through the through hole will flow to the surrounding through the guide pad 12, so that more colloid can be temporarily stored on the pick plate 11 to avoid too much colloid staying only near the through hole. It should be noted that in the initial state, the pick plate 11 is located at the bottom of the fourth bracket 412. Even after the glue dispenser 414 moves to the specified position, its bottom surface will not contact the pick plate 11, and will not affect the normal use of the pick plate 11.

[0073] During glue dispensing, the glue dispensing tube 71 is driven by the glue dispenser 414 to continuously move downward to the through-hole position, and driven by the glue dispenser 414, the glue dispensing tube 71 will pass through the through-hole. During the downward movement, the surface of the glue dispensing tube 71 contacts the inner wall of the through-hole. If the surface of the glue dispensing tube 71 is coated with colloid, the colloid will not be able to continue to move with the glue dispensing tube 71 due to the limitation of the through-hole, and will be retained on the pick-up plate 11. The removed colloid will flow to the surroundings through the guide pad 12 to avoid more colloids from accumulating near the through-hole. Finally, after the motor is assembled, the staff can clean the pick-up plate 11.

[0074] The above-mentioned device is provided with a through hole, and when the dispensing tube 71 moves up and down, the surface of the dispensing tube 71 is cleaned through the through hole. In this way, no matter what type of motor is being dispensing, it is suitable to scrape the colloid through the pick plate 11 to avoid the colloid remaining on the dispensing tube 71 and causing blockage.

[0075] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
