Description

Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to a fixture assembly and a glue dispensing device for glue dispensing. Background Art

[0002] Glue dispensing is a process, also known as gluing, coating, pouring, dripping, etc. It is to apply, pour, and drip glue or other liquid adhesives onto the product to make the product stick, pour, insulate, fix, and have a smooth surface.

[0003] In order to ensure the aesthetics and waterproof performance of the existing massagers, the glue joints are usually set in semi-hidden grooves to avoid being directly observed by users (such as Figure 1 As shown). The opening of the semi-concealed tank is horizontally oriented, and the edge of the product shell is generally higher than the semi-concealed tank, which will cause the opening of the semi-concealed tank to be blocked by the edge of the product shell in the horizontal direction. In other words, the existing standard three-axis dispensing machine cannot move the dispensing nozzle in the X-axis, Y-axis and Z-axis directions to extend the dispensing nozzle into the semi-concealed tank for dispensing. It can only rely on workers to manually hold the dispensing valve and insert it obliquely into the semi-concealed tank for dispensing. Manual dispensing has the following disadvantages: 1. The process operation efficiency is low and the dispensing speed is slow, which increases the product cost in disguise; 2. It is impossible to accurately control the dispensing amount and dispensing trajectory, which easily leads to problems such as overflow and lack of glue, and the product quality cannot be guaranteed; 3. Workers operate the dispensing nozzle repeatedly and frequently for a long time, which is labor-intensive and easy to fatigue, resulting in a further decrease in dispensing efficiency.

[0010] Furthermore, the fixture assembly also includes a photoelectric sensing module and a limit module, and the photoelectric sensing module and the limit module are respectively electrically connected to the control module. The photoelectric sensing module is suitable for detecting the rotation angle of the positioning fixture and sending a limit electrical signal to the control module after the positioning fixture rotates 360°.

[0011] Furthermore, the photoelectric sensing module includes a transmitting terminal and a receiving terminal, the transmitting terminal is arranged on the outer side wall of the positioning fixture, and the receiving terminal is arranged on the fixed plate, the positions at which the transmitting terminal and the receiving terminal are arranged correspond to each other, and the receiving terminal can periodically receive the photoelectric signal emitted by the transmitting terminal, and the receiving terminal is suitable for sending a locking electrical signal to the control module after receiving the photoelectric signal emitted by the transmitting terminal, and the control module is suitable for controlling the driving module to stop and controlling the limit module to limit the rotation of the positioning fixture according to the locking electrical signal.

[0012] Furthermore, the limit module includes a thin cylinder and a limit column transmission connected to the thin cylinder, and a limit hole cooperating with the limit column is opened on the outer wall of the positioning fixture. After receiving a locking signal, the control module can control the thin cylinder to push the limit column into the limit hole, so that the limit column cooperates with the limit hole to limit the rotation of the positioning fixture.

Then, when the fixture assembly is placed on the glue dispensing device, the glue dispensing nozzle can move in the vertical Z-axis direction and extend into the semi-concealed groove of the part to be glued for glue dispensing, thereby solving the problem that the existing three-axis glue dispensing machine cannot directly dispense glue on the semi-concealed groove on the part to be glued; at the same time, the part to be glued is tilted, and the glue can flow along the joint position of the bottom of the groove, thereby reducing or avoiding the occurrence of glue overflow.

DETAILED DESCRIPTION

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0030] In order to ensure the aesthetics and waterproof performance of the existing massagers, the glue dispensing seam is usually set in a semi-concealed groove with a horizontal opening to avoid the glue dispensing seam being directly observed by the user. Since the edge of the product shell is generally higher than the semi-concealed groove, the opening of the semi-concealed groove will be blocked by the edge of the product shell, and the glue dispensing nozzle of the glue dispensing device cannot extend into the semi-concealed groove for glue dispensing by moving in the X-axis, Y-axis and Z-axis directions.

[0031] To solve the above problems, Figure 2-4 As shown, the present application provides a fixture assembly 100 for dispensing glue, which includes a fixture seat 110 and a fixing plate 120 obliquely arranged on the fixture seat 110, and a positioning fixture 130 for positioning and installing a part 300 to be dispensed glue is arranged on the fixing plate 120, and the positioning fixture 130 is rotatably connected to the fixing plate 120 and the axis of the positioning fixture 130 is perpendicular to the fixing plate 120, so that when the part 300 to be dispensed glue is installed in the positioning fixture 130, the part 300 to be dispensed glue is tilted. The arrangement makes it possible for the seam at the bottom of the semi-concealed slot 310 of the part to be glued 300 to face the glue nozzle 210 of the glue dispensing device upward, and the glue nozzle 210 of the glue dispensing device will not be blocked by the edge of the shell of the part to be glued 300, so that the glue dispensing nozzle 210 can be easily inserted into the semi-concealed slot 310 for glue dispensing. At the same time, it can also ensure that during the glue dispensing process, glue or other adhesives flow along the seam at the bottom of the semi-concealed slot 310, thereby reducing or avoiding glue overflow.

[0032] Furthermore, the clamp seat 110 includes a bottom plate 111 and two side plates 112 connected to the two ends of the bottom plate 111, and the side plates 112 are provided with a hinged through hole 113 and an arc-shaped slide groove 114. The hinged through hole 113 is arranged at the bottom of the side plate 112, and the arc-shaped slide groove 114 is arranged at the top of the side plate 112. One end of the fixed plate 120 is hinged to the side plate 112 at the hinged through hole 113, so that the fixed plate 120 can be rotatably hinged between the two side plates 112, and the two side surfaces of the other end of the fixed plate 120 are provided with locking bolts 121 that cooperate with the arc-shaped slide groove 114. The locking bolts 121 are inserted into the arc-shaped slide groove 114, and the locking bolts 121 can slide and lock in the arc-shaped slide groove 114 to limit the fixed plate 120 at different positions, so that different inclination angles are formed between the fixed plate 120 and the bottom plate 111. Since the axis of the positioning fixture 130 is perpendicular to the fixed plate 120, when different inclination angles are formed between the fixed plate 120 and the base plate 111, the degree of inclination of the part to be glued 300 fixedly installed in the positioning fixture 130 also changes. In other words, the operator can adjust the degree of inclination of the fixed plate 120 and the part to be glued 300 by loosening the locking bolt 121, rotating the fixed plate 120, and tightening the locking bolt 121.

[0033] Because different size parameters of the parts to be glued 300 are different, the degree of inclination required for the seam position at the bottom of the semi-concealed groove 310 facing the glue nozzle 210 is also different, and the fixed plate 120 is set to a rotatable and adjustable structure, so that the clamp assembly 100 can adapt to different sizes of parts to be glued 300, thereby improving the applicability of the clamp assembly 100.

[0034] In most cases, the inclination angle between the fixing plate 120 and the bottom plate 111 is between 30° and 60°. If the inclination angle is too large or too small, the joint position at the bottom of the semi-concealed tank 310 will be blocked by the outer edge of the shell of the part 300 to be dispensed, resulting in the inability of the dispensing nozzle 210 to enter the semi-concealed tank 310. Preferably, the inclination angle between the fixing plate 120 and the bottom plate 111 is set to 45° by default. The inclination angle of 45° can adapt to most of the parts 300 to be dispensed. When encountering a part 300 to be dispensed that cannot be adapted, the operator can operate the locking bolt 121 for fine adjustment.

[0035] Furthermore, if Figure 2-4 As shown, a driving module 140 and a control module 150 are provided on the fixing plate 120, the driving module 140 is electrically connected to the control module 150, the output shaft of the driving module 140 is in transmission connection with the positioning fixture 130, and the control module 150 is suitable for controlling the driving module 140 to drive the positioning fixture 130 to rotate, so that the positioning fixture 130 rotates 360° along its own axis at a uniform speed. Preferably, the driving module 140 is implemented as a stepper motor, and the stepper motor can have better control over its rotation speed and rotation angle. Selecting a stepper motor as the driving module 140 can ensure that the driving module 140 drives the positioning fixture 130 to rotate 360° at a uniform speed.

[0036] The driving module 140 is arranged on the fixing plate 120, and its purpose is to realize automatic glue dispensing. For example, when the glue dispensing nozzle 210 enters the semi-concealed slot 310 of the glue-dispensing part 300, the control module 150 can start the driving module 140 to drive the positioning fixture 130 to rotate, so that the positioning fixture 130 rotates 360° along its own axis at a uniform speed. During the rotation of the positioning fixture 130 by 360°, the glue-dispensing part 300 fixedly installed in the positioning fixture 130 rotates together with the positioning fixture 130, and the joint position at the bottom of the semi-concealed slot 310 passes through the glue dispensing nozzle 210 in turn. The driving module 140 rotates while the glue dispensing nozzle 210 dispenses glue, so that a circle of adhesive can be evenly applied to the joint position at the bottom of the semi-concealed slot 310.

[0037] Because the glue output of the glue dispensing nozzle 210 is uniform and fixed, the driving module 140 drives the positioning fixture 130 and the glue dispensing part 300 to rotate at a constant speed to ensure that the joint position at the bottom of the semi-concealed tank 310 is evenly coated with glue, so that the glue amount and the glue dispensing trajectory can be accurately controlled to avoid uneven glue dispensing at the joint position at the bottom of the semi-concealed tank 310, resulting in partial glue shortage, partial glue accumulation, cracking, glue overflow and other problems, causing the glue dispensing part 300 to be scrapped. At the same time, the fully automatic operation of the control module 150 can save manpower and improve efficiency.

[0038] In order to ensure the dispensing effect, in some preferred embodiments, the fixture assembly 100 also includes a photoelectric sensing module 160 and a limit module 170, and the photoelectric sensing module 160 and the limit module 170 are respectively electrically connected to the control module 150, and the photoelectric sensing module 160 is suitable for detecting the rotation angle of the positioning fixture 130 and sending a locking electrical signal to the control module 150 after the positioning fixture 130 rotates 360°. The control module 150 is suitable for controlling the driving module 140 to stop working after receiving the locking electrical signal sent by the photoelectric sensing module 160, and controlling the limit module 170 to lock the positioning fixture 130, limiting the rotation of the positioning fixture 130, so as to ensure that the positioning fixture 130 rotates and only rotates 360° each time the glue is dispensed, so as to avoid the glue dispensing nozzle 210 of the glue dispensing device overlapping the glue dispensing track in the semi-concealed groove 310, resulting in glue overflow.

[0039] Specifically, in Figure 2-4 In the illustrated embodiment, the photoelectric sensing module 160 includes a transmitting terminal 161 and a receiving terminal 162. The receiving terminal 162 is fixedly disposed on the fixing plate 120 and is located below the positioning fixture 130. The transmitting terminal 161 is disposed on the outer wall of the positioning fixture 130 and can rotate with the positioning fixture 130. The positions at which the receiving terminal 162 and the transmitting terminal 161 are disposed correspond to each other. When the positioning fixture 130 is rotated to a specific position, the transmitting terminal 161 is located above the receiving terminal 162. The receiving terminal 162 can receive the photoelectric signal emitted by the transmitting terminal 161. The receiving terminal 162 is suitable for sending a locking electrical signal to the control module 150 after receiving the photoelectric signal emitted by the transmitting terminal 161. After receiving the locking electrical signal, the control module 150 controls the driving module 140 to stop rotating and controls the limit module 170 to lock the positioning fixture 130 to limit the rotation of the positioning fixture 130.

[0040] Based on the above structure, when the transmitting terminal 161 rotates with the positioning jig 130, the receiving terminal 162 can periodically receive the photoelectric signal emitted by the transmitting terminal 161. Since only one transmitting terminal 161 is set on the outer wall of the positioning jig 130, the transmitting terminal 161 needs to be rotated to the specific position again together with the positioning jig 130 so that the receiving terminal 162 can receive the photoelectric signal emitted by the transmitting terminal 161. That is to say, between the two photoelectric signals received by the receiving terminal 162, the positioning jig 130 and the transmitting terminal 161 rotated 360°. Therefore, after receiving the photoelectric signal emitted by the transmitting terminal 161, the receiving terminal 162 sends a locking electrical signal to the control module 150, which can ensure that the positioning jig 130 is limited each time it rotates 360°, ensuring that the semi-concealed slot 310 is evenly sprayed with glue or other adhesives. The positioning fixture 130 will not rotate 10° more, resulting in excessive glue or other adhesives being sprayed in the semi-concealed slot body 310 and causing glue overflow, nor will it rotate 10° less, resulting in insufficient glue or other adhesives being sprayed in the semi-concealed slot body 310 and causing glue shortage.

[0041] Furthermore, the limiting module 170 includes a thin cylinder 171 and a limiting column 172, the limiting column 172 is connected to the piston rod of the thin cylinder 171, the thin cylinder 171 is fixedly set on the fixing plate 120, and the thin cylinder 171 is located below the positioning fixture 130, and a limiting hole 131 for cooperating with the limiting column 172 is opened on the outer wall of the positioning fixture 130, and the position of the limiting column 172 corresponds to the position of the limiting hole 131. When the limiting hole 131 is aligned with the limiting column 172, the thin cylinder 171 can drive the limiting column 172 to enter the limiting hole 131, so that the limiting column 172 cooperates with the limiting hole 131 to limit the rotation of the positioning fixture 130.

[0042] In some preferred embodiments, the position of the limiting hole 131 is arranged on the same straight line as the position of the transmitting terminal 161, and the position of the limiting column 172 is arranged on the same straight line as the position of the receiving terminal 162. That is to say, when the transmitting terminal 161 rotates to the top of the receiving terminal 162 together with the positioning fixture 130, the limiting hole 131 also rotates to the top of the limiting column 172. The limiting hole 131 is aligned with the limiting column 172, and the thin cylinder 171 can drive the limiting column 172 to be inserted into the limiting hole 131.

[0043] On the other hand, the present application further provides a glue dispensing device, the glue dispensing device comprising:

[0044] A glue dispensing assembly 200, the glue dispensing assembly 200 includes a glue dispensing nozzle 210 for spraying adhesive;

[0045] and, the clamp assembly 100 described above;

[0046] When the part 300 to be glued is installed in the positioning fixture 130, the part 300 to be glued is placed at an angle, and the seam position at the bottom of the semi-concealed groove 310 is facing the glue nozzle 210 upward. The glue nozzle 210 can move up and down and extend into the semi-concealed groove 310 of the part 300 to be glued, and glue is applied to the seam position at the bottom of the semi-concealed groove 310.

[0047] The glue dispensing component 200 further includes a left and right push-pull cylinder 230 and an up and down lifting cylinder 220, which are respectively connected to the glue dispensing nozzle 210 in a transmission manner. The left and right push-pull cylinder 230 is suitable for driving the glue dispensing nozzle 210 in a horizontal direction so that the glue dispensing nozzle 210 is aligned with the semi-concealed groove 310 on the part to be glued 300 in a horizontal direction. The up and down lifting cylinder 220 is suitable for driving the glue dispensing nozzle 210 in a vertical direction so that the glue dispensing nozzle 210 can be aligned in a vertical direction and extend into the semi-concealed groove 310 on the part to be glued 300.

[0048] During the specific dispensing process, the operator installs the part to be dispensed 300 in the positioning fixture 130 connected to the driving motor, and adjusts the left and right push-pull cylinders 230 and the up and down lifting cylinders 220 so that the dispensing nozzle 210 is aligned in the horizontal and vertical directions and inserted into the semi-hidden slot 310 on the part to be dispensed 300. The control module 150 controls the driving motor to rotate and drives the part to be dispensed 300 to rotate. At the same time, the dispensing nozzle 210 evenly discharges glue. After the driving motor rotates 360°, the photoelectric controller 210 below the positioning fixture 130 The receiving terminal 162 in the sensing module 160 receives the photoelectric signal sent by the transmitting terminal 161 and sends a locking electrical signal to the control module 150. After receiving the locking electrical signal, the control module 150 controls the driving motor to stop and controls the thin cylinder 171 to work. The thin cylinder 171 pushes the limit column 172 to insert into the limit hole 131 on the outer wall of the positioning fixture 130, so that the positioning fixture 130 no longer rotates, and the dispensing nozzle 210 accurately sprays a circle of glue or other adhesives in the semi-hidden groove 310. Through the cooperation of the dispensing nozzle 210 and the driving motor, the dispensing nozzle 210 can accurately control the amount of glue and the dispensing trajectory, ensure the dispensing effect, ensure that the product is waterproof, improve the product qualification rate and reduce the waste of materials such as adhesives. During the entire operation, the operator only needs to adjust the position of the dispensing nozzle 210 and press the start button, except for installing and removing the part to be glued 300. After the position of the dispensing nozzle 210 is adjusted for the first time, the subsequent same part to be glued 300 does not need to be adjusted, which greatly reduces the operator's operation workload and avoids operator fatigue after long-term operation.

[0049] The glue dispensing component 200 also includes a pressure tank 240 for storing adhesives such as glue. The pressure tank 240 is connected to the glue dispensing nozzle 210 to supply glue to the glue dispensing nozzle 210. A glue quantity alarm module is provided in the pressure tank 240. The glue quantity alarm module is suitable for detecting the glue quantity in the pressure tank 240 and issuing an alarm when the glue quantity is lower than a set value.

[0050] Common glue quantity alarm modules include a buzzer, a laser transmitter, and a photosensitive sensor. The laser transmitter is suitable for emitting a red laser to the photosensitive sensor, and the photosensitive sensor is suitable for controlling the buzzer to alarm when receiving the red laser. Specifically, when the liquid level in the pressure tank 240 is higher than the laser transmitter, the red laser emitted by the laser transmitter is blocked by adhesives such as glue and cannot be irradiated to the photosensitive sensor, and the buzzer does not sound an alarm; when the liquid level in the pressure tank 240 is lower than the laser transmitter, the red laser emitted by the laser transmitter irradiates the photosensitive sensor, and the buzzer sounds an alarm, indicating that the liquid level in the pressure tank 240 is too low.

[0051] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
