Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and particularly to an automatic glue coating mechanism for a battery water cooling plate. Background Art

[0002] During the use of power batteries, they are often in a state of high energy density and high-power discharge. In this state, a large amount of heat is usually generated. To ensure the long-term stable operation of power batteries, a cooling structure needs to be set up in the battery module for cooling and heat dissipation. Commonly, a water cooling plate is used for cooling. The heat is mainly transferred by the contact between the battery module and the surface of the water cooling plate, and the coolant in the internal flow channel of the water cooling plate can accelerate the spread of heat, achieving the effect of quickly reducing the battery temperature and ensuring that the operating temperature of the battery is in a healthy state. Generally, there is a certain gap between the battery module and the water cooling plate for coating heat-conducting glue, and the heat-conducting glue can improve the heat conduction efficiency from the battery core to the surface of the water cooling plate.

[0003] Currently, the battery module and the water cooling plate are mainly fixedly connected to the frame through a glue coating plus FDS connection method, that is, before installing the water cooling plate, the water cooling plate is coated with glue according to the designed glue coating path, and the tooling is used to fit and press against the frame to make the glue spread out flatly, and finally FDS is carried out. In the glue coating and FDS connection processes, relatively independent and mature devices are generally used in combination. For example, a manipulator is used to replace the traditional manual operation for glue coating.

[0004] An AGV cart generally refers to a transport vehicle equipped with automatic navigation devices such as electromagnetic or optical devices, which can travel along a specified navigation path, has safety protection and various load transfer functions. In industrial applications, it does not require a driver to operate, and a rechargeable battery is used as its power source. Generally, its traveling path and behavior can be controlled by a computer, or its traveling path can be set up by using an electromagnetic track, and the electromagnetic track is laid on the floor to achieve the effect of automatically transporting workpieces.

[0005] Since the processing devices before and after the glue coating of the water cooling plate are relatively independent and scattered, and the glue coating has high positioning requirements for its workpieces, the current positioning system of the AGV cart is relatively simple, mainly for the transfer start and stop on the same horizontal plane, and cannot meet the tooling positioning requirements of the glue coating manipulator. Therefore, at present, manual operation is still relied on for workpiece transfer. This method has a large labor intensity and low efficiency. In addition, the skill levels of different operators vary greatly, resulting in unstable tooling positioning quality between different workpieces and an easy increase in the defective product rate. Summary of the Invention

[0006] The main purpose of the present invention is to provide an automatic glue coating mechanism to improve the automation degree of the glue coating process of the water cooling plate, replace the existing manual transfer operation, reduce the labor intensity, and ensure the stability of the processing quality.

[0007] A secondary object of the present invention is to improve the positioning structure of the water-cooled plate workpiece, enhance the adaptability between the AGV vehicle and the gluing manipulator, and thus improve the production and processing efficiency.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] An automatic gluing mechanism is applied to the gluing process of the water-cooled plate. The gluing mechanism includes a manipulator and an AGV vehicle. A glue head is installed on the manipulator for gluing the water-cooled plate. The glue head is connected to a glue supply module. The AGV vehicle is used to load and transport the water-cooled plate. A positioning device is arranged outside the manipulator.

[0010] Wherein, the positioning device includes two spaced-apart positioning brackets, and a positioning channel for the AGV vehicle to pass through is formed between the two positioning brackets.

[0011] A guiding structure is arranged inside the positioning bracket for restricting and positioning the traveling route of the AGV vehicle in the positioning channel.

[0012] A blocking member is arranged at the rear end of the positioning bracket. The blocking member has a blocking structure that can open and close horizontally inside the positioning bracket for blocking and positioning the traveling of the AGV vehicle in the positioning channel.

[0013] A supporting member and a pushing member are arranged at the top of the positioning bracket, and supporting rollers are arranged at the top of the supporting member.

[0014] The top of the AGV vehicle is a bearing platform. A bearing bracket is connected below the bearing platform. A buffer block adapted to the blocking member is arranged at the front side of the bearing bracket. Supporting platforms and force-receiving blocks adapted to the supporting member and the pushing member respectively are arranged at the bottom of the bearing platform. The supporting platform is a convex platform structure that is inclined forward and backward and bulges downward. The pushing member can abut against the force-receiving block and push the AGV vehicle forward, so that the supporting platform climbs to the top of the supporting rollers. At the same time, the buffer block closely abuts against the blocking structure of the blocking member, jointly constituting a positioning structure.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] The present invention uses an AGV trolley to carry and transport water-cooled plates to replace manual operation. On the basis of the existing AGV trolley structure, the positioning structure is improved and upgraded, and structures such as a support platform, a force-bearing block and a buffer block are used to respectively adapt to the support, pushing and blocking structures of the positioning device, and a guide structure is set to constrain the walking route of the AGV trolley. When the AGV trolley is transported to the gluing station on one side of the manipulator, it can be positioned and fixed in the horizontal direction left and right and front and back bidirectionally, and can also be lifted and positioned longitudinally on this basis to form a three-dimensional, multi-layered covering positioning structure, thereby overcoming the inability of the traditional AGV trolley positioning system to meet the high-precision positioning requirements of the manipulator for gluing. Therefore, mechanical automated transport equipment can be used to replace manual operation, improve the degree of automation, reduce labor intensity, and avoid the phenomenon of unstable product tooling positioning quality and high defective rate due to uneven skill levels of operators.

[0017] On the basis of the above technical solution, in order to ensure the accuracy of the gluing action after each startup, a glue nozzle correction device is provided on one side of the robot.

[0018] On the basis of the above technical solution, in order to ensure that the gluing effect meets the requirements, a calibration table is provided on one side of the manipulator for inspecting the first workpiece.

[0019] On the basis of the above technical solution, the top of the positioning bracket is provided with an extension plate, the support member is installed on the top of the extension plate, and one side of the support member is connected with an adjustment rod for adjusting the horizontal position of the support member. This helps to fine-tune the installation position of the support member according to the operation requirements and the different models, specifications and structures of the AGV trolleys, so that it can work normally after flexible adjustment.

[0020] Based on the above technical solution, the propulsion member includes a propulsion driving member, which is transmission-connected to a slider. The slider can move linearly back and forth parallel to the traveling direction of the AGV trolley. The slider is connected to a propulsion block, which is used to abut the rear side wall of the force-bearing block.

[0021] The use of propulsion components to assist the AGV in making the final fine-tuning movement in the positioning channel and the combination of multiple positioning structures helps to ensure efficient and accurate positioning.

[0022] On the basis of the above technical solution, the top of the propulsion block extends to above the slider, and a guide slope is provided on the top of the propulsion block. The guide slope gradually rises along the travel direction of the AGV trolley and forms a vertical plane at the end of the vertex. The guide slope is located on the travel path of the force-bearing block, and the vertical plane is used to abut against the rear side wall of the force-bearing block; a groove is provided on the slider, and the bottom of the propulsion block is pivotally connected to the inner side wall of the groove, and the top of the propulsion block forms a one-way check structure with a flipping function.

[0023] By setting up the structure where the guiding inclined plane, the pushing block and the slider are pivotally connected, a one-way check structure is formed, making the positioning of the AGV vehicle more efficient and preventing it from swaying in the front-back direction during the gluing process, further ensuring the stability of the tooling during the gluing process.

[0024] Based on the above technical solution, the blocking member includes a blocking driving member fixed to the rear end of the positioning bracket, the blocking structure is arranged at the inner end of the blocking driving member, the blocking structure includes a blocking movable member, a swinging member is pivotally connected to the inner end of the blocking movable member, a blocking roller and a positioning member are arranged on the swinging member, and a positioning groove adapted to the positioning member is further arranged on the blocking movable member.

[0025] After the blocking driving member drives the blocking structure inward, a blocking state is formed. After the buffer block on the AGV vehicle moves forward, it will push the blocking roller, drive the swinging member to swing, and the swung positioning member enters the positioning groove, constituting a blocking-in-place constraint structure; when the blocking driving member drives the blocking structure outward, the blocking state is released, and the AGV vehicle can drive out from the positioning channel.

[0026] By setting up a laterally movable blocking structure, the opening and closing control of the blocking structure is formed, and structures such as the blocking movable member, the swinging member, the blocking roller, the positioning member, and the positioning groove are integrated into a compact small-volume structure, avoiding structural bulkiness. The structural design of the blocking roller can reduce the hard impact on the buffer block during the blocking process and prevent structural wear, which helps to extend the service life and improve the utilization rate of components.

[0027] Based on the above technical solution, a positioning sensor is arranged on the positioning bracket. By adding a sensor to detect the in-place state of the AGV vehicle, accurate feedback on the positioning effect can be provided in multiple directions and through multiple channels, which helps to improve the operation accuracy of the mechanism.

[0028] Based on the above technical solution, two gluing stations are symmetrically arranged outside the manipulator. Each gluing station is provided with the positioning device and the AGV vehicle that cooperates with the positioning device. This helps to improve the utilization rate of the manipulator. A manipulator can perform alternating operations on the gluing stations on both sides during the in-and-out travel of the AGV vehicle, thereby reducing the waiting time for workpiece loading and unloading and the idle standby time of the manipulator. This method also helps to reduce the burden on the glue supply module for glue feeding control, making the gluing action more continuous and smooth, and further improving the production and processing efficiency.

Specific Embodiments

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1, asFigure 1 As shown in the figure, this embodiment discloses an automatic glue coating mechanism for a water-cooled plate in battery processing. The automatic glue coating mechanism is composed of a glue supply module 100, a manipulator 200, an AGV cart 300, a positioning device 400, a calibration table 500, and a glue nozzle calibration device 600.

[0041] Among them, the glue supply module 100 includes a metering device 110, a feeding bracket 120, and a movable crossbeam 130 pivotally connected to the feeding bracket 120. The feeding bracket 120 mainly plays a bearing role and is used to install a glue pipe, and even includes a glue storage container. The metering device 110 is a prior art, and its specific structure and working principle will not be elaborated here. It is mainly used to measure and control the flow of the glue to ensure that the glue can be stably transported according to the operation requirements. The movable crossbeam 130 is pivotally connected to the top of the feeding bracket 120 and can rotate accordingly according to the actions during the processing of the manipulator 200, so as to ensure that the glue pipe will not be pulled due to the large-scale movement of the manipulator 200 and affect the stability of glue supply.

[0042] The manipulator 200 in this embodiment is a prior art and will not be elaborated here. It mainly realizes multi-axis linkage of the manipulator 200, and a fixture 210 and a glue head 220 are arranged at the end of the manipulator 200. By combining with the glue supply module 100 located on one side, it can coat the water-cooled plate at the glue coating station according to the pre-set motion path parameters.

[0043] Furthermore, in order to ensure the accuracy of the glue coating action after each startup, a glue nozzle calibration device 600 is arranged on one side of the manipulator 200 to calibrate the initial position of the glue nozzle tooling at the end of the glue head 220.

[0044] Furthermore, in order to ensure that the glue coating effect meets the requirements, a calibration table 500 is arranged on one side of the manipulator 200 to inspect the first piece of the workpiece.

[0045] Among them, the glue nozzle calibration device 600 and the calibration table 500 are prior arts, and their structures will not be elaborated here.

[0046] In this embodiment, the AGV cart 300 mainly serves as a carrier for carrying and transporting water-cooled plate workpieces. The water-cooled plate is horizontally fixed and tooled on the top of the AGV cart 300, replacing the existing method of manually transporting water-cooled plate workpieces. This method helps to reduce the labor intensity of operators, improve the automation degree of water-cooled plate glue coating processing, and ensure the stability of processing quality.

[0047] In this embodiment, the number of the positioning devices 400 is one, which is arranged on one side of the manipulator 200. Specifically, the positioning device 400 includes two positioning brackets distributed at intervals, namely a first positioning bracket 41 and a second positioning bracket 42. A positioning channel for the AGV cart 300 to pass through is formed between the two positioning brackets.

[0048] The AGV cart 300 can cooperate with the positioning brackets in the positioning channel to complete positioning and stay fixed. This fixed position serves as the gluing station, and then the manipulator 200 performs a gluing operation on the water-cooled plate located at this gluing station. After gluing, the AGV cart 300 drives out of the positioning device 400 and transports the water-cooled plate to the processing device of the next process.

[0049] Embodiment 2, based on Embodiment 1, combined with Figure 2 , two guiding plates 43 are symmetrically arranged on the inner sides of the two positioning brackets.

[0050] Define the length direction of the positioning bracket as the front-back direction, and the width direction as the left-right direction, that is, the AGV cart 300 moves from the back to the front ( Figure 1 which is shown as from left to right in the drawing) and enters the positioning device 400.

[0051] The guiding plate 43 is specifically located near the bottom on the inner side of the positioning bracket, and the rear end of the guiding plate 43 is a wire protection guardrail structure that bends and extends outwards, forming a reduced-opening guiding track structure with a larger outer and a smaller inner size. Combined with Figure 6 , a bearing bracket 32 is provided at the bottom of the AGV cart 300. When the AGV cart 300 enters the positioning channel, the outer side walls of both sides of the bearing bracket 32 are respectively abutted against the inner side walls of the two guiding plates 43, forming a guiding structure for restricting and positioning the walking route of the AGV cart 300 in the positioning channel, so as to keep it positioned stably in the left-right direction.

[0052] The bottoms of the first positioning bracket 41 and the second positioning bracket 42 are locked and installed on the ground through feet with adjustable heights, which helps to finely adjust the installation level of the positioning brackets.

[0053] Embodiment 3, based on Embodiment 2, as Figure 2 shown, a blocking member 46 is provided at the rear end of the positioning bracket (relative to the action of the AGV cart 300 entering the positioning device 400, this rear end and the driving-out end of the AGV cart 300 in the positioning channel). The blocking member 46 has a blocking structure that can open and close horizontally on the inner side of the positioning bracket, and is used for blocking and positioning the walking of the AGV cart 300 in the positioning channel.

[0054] Specifically, combined with Figure 2 and Figure 5, the blocking member 46 includes a horizontally arranged blocking cylinder 461 with its telescopic rod facing inwards. The blocking cylinder 461 is connected and fixed to the first positioning frame or the second positioning frame through a blocking base 462 with an L-shaped cross-section. The connection method adopts a combination of bolts and strip holes, which can finely adjust its installation position.

[0055] A blocking structure is connected to the inner end of the blocking cylinder 461, and the blocking cylinder 461 can drive the blocking structure to move horizontally inwards or outwards. The blocking structure includes a blocking movable member 463, which is fixedly connected to the inner end of the telescopic rod of the blocking cylinder 461 and can move in and out with it. A swinging member 464 is pivotally connected to the inner end of the blocking movable member 463, and its pivot axis is arranged vertically. A blocking roller 465 and a positioning member 466 are provided on the swinging member 464. The blocking roller 465 is connected to the swinging member 464 through a vertical rotating shaft. The positioning member 466 is specifically a vertical rod structure, and a positioning groove 467 adapted to the positioning member 466 is also provided on the blocking movable member 463.

[0056] To ensure the transverse movement stability of the blocking movable member 463, a limiting groove 4631 is provided on the blocking movable member 463, and a limiting rod 4621 adapted to it is provided on the blocking base 462, and the two form a linear guiding structure.

[0057] Combined Figure 6 , on the left and right sides of the front side wall of the bearing bracket 32 of the AGV cart 300, two buffer blocks 34 are symmetrically provided for cooperating with the blocking member 46 to complete the front and rear direction positioning of the AGV cart 300.

[0058] After the blocking driving member drives the blocking structure inwards, a blocking state is formed. After the buffer block 34 on the AGV cart 300 travels, it will push the blocking roller 465, driving the swinging member 464 to swing. At this time, it can play a buffering role in the travel of the AGV cart 300. Further, the swung positioning member 466 finally enters the positioning groove 467 to form a blocking-in-place constraint structure; when the blocking driving member drives the blocking structure outwards, the blocking state is released, and the AGV cart 300 can drive out from the positioning channel. During this process, the blocking roller 465 can play a role of rolling guidance.

[0059] By setting a transversely movable blocking structure, the opening and closing control of the blocking structure is formed, and structures such as the blocking movable member 463, the swinging member 464, the blocking roller 465, the positioning member 466, and the positioning groove 467 are integrated into a compact and small-volume structure, avoiding structural bulkiness. The structural design of the blocking roller 465 can reduce the hard impact on the buffer block 34 during the blocking process and prevent the phenomenon of structural wear, which helps to extend the service life and improve the component utilization rate.

[0060] Example 4, based on Example 3, as Figure 2 shown, a support member 44 and a propulsion member 45 are provided at the top of the positioning bracket, and a support roller 442 is provided at the top of the support member 44.

[0061] As Figure 6 shown, the top of the AGV cart 300 is a loading platform 31, and the top of the loading platform 31 is used for fixing the water-cooled plate with a tooling. A loading bracket 32 is connected below the loading platform 31. A buffer block 34 adapted to the blocking member 46 is provided on the front side of the loading bracket 32. Support platforms 35 and force-receiving blocks 36 adapted to the support member 44 and the propulsion member 45 respectively are provided at the bottom of the loading platform 31. The support platform 35 is a convex platform structure that is inclined forward and backward and bulges downward. The propulsion member 45 can abut against the force-receiving block 36 and push the AGV cart 300 forward, so that the support platform 35 climbs to the top of the support roller 442. At the same time, the buffer block 34 closely abuts against the blocking structure of the blocking member 46, jointly forming a positioning structure. A traveling wheel 33 with a universal wheel structure is provided at the bottom of the support bracket and is connected with a driving mechanism, which can independently carry out transfer and feeding. This part of the structure is prior art and will not be elaborated here. Handles 37 are also provided on both the front and rear sides of the loading platform 31, which is convenient for manually dragging the AGV cart 300.

[0062] Furthermore, as Figure 2 、 3 shown, a horizontal extension plate 48 is fixedly installed at the top of the positioning bracket, and the support member 44 is installed on the top of the extension plate 48. Specifically, the support member 44 includes a support seat 441 connected to the extension plate 48 by bolts. Through the combined structure with the strip-shaped holes, the installation position of the support seat 441 can be horizontally fine-tuned. A support roller 442 is installed on the top of the support seat 441, and the rotating shaft of the support roller 442 is horizontally arranged. In this embodiment, its rolling direction is parallel to the front-rear direction. The main function of the support roller 442 is to abut against the bottom surface of the support platform 35 and support the AGV cart 300.

[0063] In other embodiments, the support roller 442 can also adopt a universal wheel, so that its auxiliary guidance for the AGV cart 300 is not limited to one direction. Of course, when using a universal wheel, the left-right displacement of the universal wheel should be controlled within the width range of the support platform 35 to prevent the support platform 35 from falling off the support wheel.

[0064] One side of the support member 44 is connected with an adjusting rod 443. The adjusting rod 443 specifically adopts an adjusting screw rod and is used to adjust the horizontal position of the support member 44. This helps to fine-tune the installation position of the support member 44 according to the operation requirements and the different model specifications of the AGV cart 300, so that it can work properly after flexible adjustment. To further ensure the stability of its horizontal position adjustment, as Figure 4As shown in the figure, a flange 4411 with a linear structure is provided at the bottom of the support base. Correspondingly, a guiding groove 481 adapted to it is provided on the extension plate 48. When the support base 441 moves horizontally, the flange 4411 slides in the guiding groove 481, playing a role of linear guiding.

[0065] Furthermore, in combination with Figure 2 and Figure 3 , a pusher 45 is also provided on the extension plate 48 for assisting in positioning and pushing the AGV cart 300. Specifically, the pusher 45 includes a pushing cylinder 451 fixed on the extension plate 48. The telescopic rod of the pushing cylinder 451 is arranged in the front-back direction. A connecting block 452 is fixedly connected to the end of the telescopic rod. A slider 453 is fixedly connected to the rear end of the outer side of the connecting block 452, making its combined structure more compact and small, and can make full use of the space for displacement. The slider 453 can perform linear reciprocating movement parallel to the traveling direction of the AGV cart 300. A pushing block 454 is connected to the slider 453, and the pushing block 454 is used to abut against the rear side wall of the force-bearing block 36. To ensure the movement stability of the pushing block 454, a slide rail 455 is also provided between the slider 453 and the extension plate 48 to play a guiding role.

[0066] The pusher 45 is used to assist the AGV cart 300 in performing final stroke fine-tuning movement in the positioning channel, and the combination of multiple positioning structures helps to make the positioning process efficient and accurate.

[0067] Furthermore, in combination with Figure 7 , the top of the pushing block 454 extends above the slider 453. A guiding inclined surface 4541 is provided on the top of the pushing block 454, and the guiding inclined surface 4541 gradually climbs along the traveling direction of the AGV cart 300 for longitudinal positioning.

[0068] As Figure 3 shown in the figure, a vertical plane is formed at the vertex end of the pushing block 454. The guiding inclined surface 4541 is located on the traveling path of the force-bearing block 36, and this vertical plane is used to abut against the rear side wall of the force-bearing block 36; a sunk groove is provided on the slider 453, and the bottom of the pushing block 454 is pivotally connected to the inner side wall of the sunk groove. The top of the pushing block 454 forms a one-way check structure with a flipping function. By setting the guiding inclined surface 4541 and the structure in which the pushing block 454 is pivotally connected to the slider 453, a one-way check structure is formed, making the positioning of the AGV cart 300 more efficient and preventing it from swaying in the front-back direction during the gluing process, further ensuring the stability of the tooling during the gluing process.

[0069] In combination with Figure 1 , Figure 2 , Figure 6 , Figure 8In the specific implementation process, when the AGV trolley 300 enters the positioning channel, the left and right sides of the support bracket 32 ​​first contact the guide plate 43 to perform the first positioning process, so as to realize the left and right positioning of the AGV trolley 300. The blocking cylinder 461 pushes the blocking structure inward to the blocking state. After the AGV trolley 300 continues to move forward, the buffer block 34 contacts the blocking roller 465 and drives the swing member 464 to partially swing and perform the buffering process. At this time, the AGV trolley 300 automatically drives to stop, and at the same time, as shown in FIG. Figure 8 As shown in the upper part, the force block 36 has passed the guide slope 4541 and is located in the rear area of ​​the propulsion block 454. In this state, the one-way check structure of the propulsion block 454 has taken effect. If the AGV trolley 300 slides backward, it will be blocked by the propulsion block 454. At this time, the support platform 35 is not yet at the upper end of the support roller 442. Next, the push cylinder drives the propulsion block 454 to move forward, so that the front side wall of the propulsion block 454 abuts against the rear side wall of the force block 36, and pushes the AGV trolley 300 forward until it is as shown in FIG. Figure 8 As shown in the lower part, the support platform 35 climbs to the top of the support roller 442. In this state, the AGV trolley 300 is lifted to the preset height as a whole for longitudinal positioning, thus completing the second positioning process. In this state, since the AGV trolley 300 cannot move backward, the push block 454 can accurately and stably push the AGV trolley 300 forward. After pushing it to the target stroke, the situation at the front end of the support bracket is: the buffer block 34 continuously abuts against the blocking roller 465 and pushes it forward, so that the swing member 464 continues to swing outward and forward until the positioning member 466 enters the positioning groove 467, and performs the front and rear direction in-place constraint, completing the third positioning process. Then the manipulator 200 applies glue to the water-cooled plate on the top of the AGV trolley 300. After the gluing is completed, the blocking cylinder 461 retracts the blocking structure outward, contacts the blocking state, and the AGV trolley 300 drives itself out of the positioning channel and moves the next process processing device.

[0070] It should be noted that three groups of positioning sensors 47 are also provided on the first positioning bracket 41 and the second positioning bracket 42 for detecting the position of the water cooling plate and the AGV trolley 300, realizing high-precision position detection, and coordinating with various transmission components to achieve precise positioning.

[0071] Among them, the three positioning processes work together synchronously to build a three-dimensional, multi-layered covering positioning structure, thereby overcoming the problem that the traditional AGV cart 300 positioning system cannot meet the high-precision positioning requirements of the manipulator 200 for gluing. Therefore, mechanical automated transfer equipment can be used to replace manual operation, improve the degree of automation, reduce labor intensity, and avoid the phenomenon of unstable product tooling positioning quality and high defective rate due to uneven skill levels of operators.

[0072] Embodiment 5, asFigure 9 As shown, two glue - applying stations are symmetrically arranged outside the manipulator 200. Each glue - applying station is provided with the positioning device 400 and the AGV cart 300 that works in coordination with the positioning device 400. This helps to improve the utilization rate of the manipulator 200. A manipulator 200 can alternately operate on the glue - applying stations on both sides during the in - and - out travel of the AGV cart 300, thereby reducing the waiting time for workpiece loading and unloading and the idle standby time of the manipulator 200. This method also helps to reduce the burden of the glue supply module 100 on glue - feeding control, making the glue - applying action more continuous and smooth, and further improving the production and processing efficiency.
