Description

Technical Field

[0001] The present invention relates to the technical field of product assembly, and in particular to a positioning device, a dispensing device and a product assembly method. Background Art

[0002] In industries like electronics manufacturing and precision device assembly, the glue dispensing process is crucial for ensuring product sealing, structural stability, and functional reliability. Glue dispensing equipment typically uses a fixture to secure the product to be processed. Mechanical positioning or manual assistance is used to initially secure the product within the fixture, followed by the application of glue by an automated dispensing system.

[0003] In existing technology, dispensing equipment consists of a basic positioning module, a vertical clamping mechanism, and a manual adjustment interface. The basic positioning module is machined from a rigid material (such as aluminum alloy) into a cavity that matches the product's contours. The inner wall of the cavity restricts the product's horizontal freedom. The vertical clamping mechanism is equipped with an elastic pressure block or pneumatic push rod to prevent product warping by applying vertical pressure. The manual adjustment interface has adjustment holes reserved on the side or top of the fixture, equipped with micro screws or ejectors, allowing the operator to manually fine-tune the product's position.

[0004] During operation, the operator must first roughly place the product into the mold cavity, visually or using simple measuring tools (such as a magnifying glass or ruler) to determine the deviation between the product and the preset dispensing path. Then, using tools such as a screwdriver to rotate and adjust the ejector pin, the operator gradually corrects the product's position. For smaller products, the operator must repeatedly adjust and confirm the position. This adjustment process is time-consuming and prone to operational fluctuations due to fatigue, resulting in lower overall production efficiency and a high risk of large positioning deviations, resulting in poor quality of the bonded product. Summary of the Invention

[0005] The purpose of the present invention is to provide a positioning device, a dispensing device and a product assembly method to solve the problem in the prior art that small products need to be repeatedly positioned and adjusted before dispensing, resulting in overall long time consumption, low efficiency, and easy occurrence of large positioning deviations, resulting in poor product quality after bonding.

[0050] transporting the second product into the second space and positioning it;

[0051] The second product is pushed to fit the first product and the first product and the second product are squeezed and dried to complete the assembly of the first product and the second product.

[0052] Beneficial effects of the present invention:

[0053] On the one hand, by setting up a first positioning mechanism and a second positioning mechanism, when the first product is placed in the first space of the fixture, the first positioning mechanism is used to press against both sides of the first product, and the side of the first product to be glued is exposed for applying glue, and then the second product is placed in the second space to form a plug-in fit with the second positioning mechanism, thereby fixing the second product, and then the second positioning mechanism is used to push the second product close to the first product to complete the assembly and bonding of the two. Therefore, when the positioning device is in use, it is only necessary to use a structure such as a manipulator to place the smaller first product into the first space and the second product into the second space. The first positioning mechanism and the second positioning mechanism can automatically and accurately position them without the need for further correction or repeated operation, thereby effectively saving the time spent on product positioning and helping to improve overall production efficiency. At the same time, the first space and the second space are respectively adapted to the first product and the second product, so that the positioning accuracy of the products is high, and the two can remain aligned during bonding, thereby effectively improving the quality of the bonded products.

[0054] Secondly, when assembling the first product and the second product, first install the fixture of the positioning device, and then use the mobile module to drive the positioning device to the loading position, move the first product into the first space and use the first positioning mechanism to position the first product, and then the mobile module drives the positioning device to the gluing position, and the gluing device applies the glue on the surface of the first product. The mobile module then drives the positioning device to the loading position, and the second product is moved into the second space and the positioning is completed. The second positioning mechanism is then used to push the second product close to the first product, and the pressure cover is moved to the positioning device, the first product and the second product are squeezed, and the positioning device and the pressure cover are moved to the baking equipment for drying. After drying, the positioning device and the pressure cover are moved to the mobile module and removed from the pressure cover. The mobile module then drives the positioning device to the loading position, and the assembled product is moved away and re-loaded to repeat the above process. Therefore, during the use of the dispensing equipment, the positioning device can automatically complete the positioning of the first product and the second product without manual intervention and multiple adjustments, thereby effectively saving the time spent on positioning small products, making the product bonding and assembly process less time-consuming, which is conducive to improving the overall processing efficiency. At the same time, the positioning accuracy can be guaranteed only after the equipment debugging is completed, ensuring the high quality of the bonding and assembly of batch products.

[0055] Thirdly, through this method, when gluing and assembling small products, the first product is first moved and positioned and glued, and then the second product is moved for positioning and gluing, so that the first product and the second product are positioned separately, and the positioning is achieved using the corresponding spatial structure, so that the positioning can be completed once, thereby effectively saving the time spent on positioning, and ensuring high positioning accuracy, thereby improving product assembly efficiency and effectively ensuring the quality of the assembled products.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0079] The embodiments of the present invention disclose a positioning device, glue dispensing equipment and a product assembly method.

[0080] Reference Figures 1 to 3 The positioning device includes a base 1, a fixture 2, a first positioning mechanism 3, and a second positioning mechanism 4. The fixture 2 is mounted on the base 1 and defines a first space 21 for accommodating a first product 5. The first positioning mechanism 3 is mounted on the fixture 2 and partially corresponds to the first space 21. The first positioning mechanism 3 presses against two sides of the first product 5 to secure the first product 5. The second positioning mechanism 4 is mounted on the fixture 2 and defines a second space for accommodating a second product 6. The second positioning mechanism 4 engages with the second product 6 and can move the second product 6 toward or away from the first product 5 within the first space 21.

[0081] Specifically, the base 1 is fixed on the corresponding table, and the clamp 2 is set on the base 1. The two can form a non-detachable fixed connection by welding or bonding, or a detachable fixed connection by snap-fitting or plug-in fitting. The clamp 2 is provided with a relative first space 21 and a second space, wherein the first space 21 and the second space can be adapted to the first product 5 and the second product 6 respectively, and the first product 5 and the second product 6 are both small products of smaller size. In order to improve adaptability, the first space 21 and the second space can be respectively opened on the corresponding block structure, and the block structure and the clamp 2 can form a detachable connection, so as to facilitate the block structure with different shapes of spaces according to different products.

[0082] The first positioning mechanism 3 is disposed on the base 1 and is movably connected to the clamp 2 and extends into the first space 21. The first positioning mechanism 3 can abut against two side surfaces of the first product 5, such as the side surface and top surface, the side surface and back surface, or two opposite sides, so as to apply external force to the first product 5 in two directions to fix the first product 5. The second positioning mechanism 4 is disposed corresponding to the first space 21 and forms a second space. The second product 6 can be placed in the second space and form a plug-in fit with the second positioning mechanism, thereby fixing the second product 6 in the second space. After the first product 5 is coated with glue, the second positioning mechanism 4 can drive the second product 6 close to the first product 5 so that the two form a close bond.

[0083] By setting up the first positioning mechanism 3 and the second positioning mechanism 4, after the first product 5 is placed in the first space 21 of the fixture 2, the first positioning mechanism 3 is used to press against both sides of the first product 5, and the side of the first product 5 to be glued is exposed for applying glue, and then the second product 6 is placed in the second space to form a plug-in fit with the second positioning mechanism 4, thereby fixing the second product 6, and then the second positioning mechanism 4 is used to push the second product 6 close to the first product 5 to complete the assembly and bonding of the two. Therefore, when the positioning device is in use, it is only necessary to use a structure such as a robot to place the smaller first product 5 into the first space 21 and the second product 6 into the second space. The first positioning mechanism 3 and the second positioning mechanism 4 can automatically and accurately position them without the need for further correction or repeated operation, thereby effectively saving the time spent on product positioning and helping to improve overall production efficiency. At the same time, the first space 21 and the second space are respectively adapted to the first product 5 and the second product 6, so that the positioning accuracy of the products is high, and the two can remain aligned during bonding, thereby effectively improving the quality of the bonded products.

[0084] Reference Figure 3 and Figure 5 Optionally, the first positioning mechanism 3 includes a side positioning assembly 31 and a top positioning assembly 32. The side positioning assembly 31 is movably connected to the fixture 2 and partially extends into the first space 21. The side positioning assembly 31 is used to press against the side of the first product 5; the top positioning assembly 32 is movably connected to the fixture 2 and corresponds to the first space 21 and is used to press against the top wall of the first product 5.

[0085] Specifically, the first space 21 has a semi-enclosed structure, so that one side of the first product 5 abuts against the side of the first space 21. A limiting protrusion 22 can also be provided on the side of the first space 21 adjacent to the second space to restrict the movement of the first product 5. The side positioning assembly 31 is movable horizontally and abuts against the other side of the first product 5, thereby securing the first product 5 in the horizontal plane. The top positioning assembly 32 partially protrudes from the upper side of the fixture 2 to correspond to the upper side of the first space 21 and abuts against the top wall of the first product 5, thereby securing the first product 5 vertically.

[0086] By setting up the side positioning component 31 and the top positioning component 32, after the first product 5 is placed in the first space 21, the side positioning component 31 can be used to position the side of the first product 5, and the top positioning component 32 can be used to position the top surface of the first product 5. Pressure can be applied to both sides of the first product 5 to firmly fix the first product 5 in the first space 21. Even if the size of the first product 5 is small, it is only necessary to ensure that the first product 5 is adapted to the shape of the first space 21. The first product 5 can be accurately positioned in the first space 21 without repeatedly calibrating the first product 5, which effectively simplifies the positioning process of the first product 5 and saves the time spent on positioning.

[0087] Optionally, the side positioning assembly 31 includes a side positioning portion 311 and a side transmission portion 312. The side positioning portion 311 is slidably connected to the fixture 2 along a first direction X, and one end of the side positioning portion 311 can abut against the side surface of the first product 5. The side transmission portion 312 is slidably connected to the fixture 2 along a second direction Z and is connected to the side positioning portion 311 to push the side positioning portion 311 toward or away from the side surface of the first product 5. The first direction X and the second direction Z intersect.

[0088] Specifically, a notch is provided on the clamp 2 as an installation space for the side positioning portion 311 and the side transmission portion 312. The side positioning portion 311 is block-shaped, and a side panel 313 can be provided on the side close to the first space 21. The side panel 313 is inserted into the first space 21, and the edge of the side panel 313 is bent to extend a side tightening portion 314. The size of the side tightening portion 314 is adapted to the size of the first product 5, so that the side tightening portion 314 can just fit on the side of the first product 5.

[0089] The first direction X can be the length of the first product 5, i.e., the side positioning portion 311 slides along the length of the first product 5. The second direction Z is a vertical direction, perpendicular to the first direction X, i.e., the side transmission portion 312 slides in the vertical direction. This sliding can be driven by a cylinder as a driving element, or by a motor in conjunction with other structures. The side transmission portion 312 and the side positioning portion 311 can be connected to each other through a connecting rod assembly, so that when the side transmission portion 312 moves in the second direction Z, it can drive the side positioning portion 311 to move in the first direction X. The transmission connection between the two can also be achieved through inclined planes or other connecting structures.

[0090] By providing the side positioning portion 311 and the side transmission portion 312, when the first product 5 needs to be positioned, the side positioning portion 311 is driven by the side transmission portion 312 to move, so that the side positioning portion 311 approaches the side of the first product 5 until the side positioning portion 311 is in contact with the side of the first product 5. When the positioning needs to be released, the side transmission portion 312 drives the side positioning portion 311 to move in the opposite direction, so that the side positioning portion 311 is away from the first product 5. By sliding the side positioning portion 311 and the side transmission portion 312 along the intersecting first direction X and second direction Z, respectively, the entire side positioning assembly 31 becomes more compact and smaller in size, avoiding the problem of being too large in a single direction and difficult to accurately position small products.

[0091] Optionally, the side transmission portion 312 has an extrusion slope 315 that is in contact with the side positioning portion 311 and extends along the second direction Z. A side elastic member 316 is provided on the side of the side positioning portion 311 away from the side transmission portion 312. The side elastic member 316 is used to push the side positioning portion 311 against the extrusion slope 315.

[0092] Specifically, an extrusion slope 315 is provided on the side of the side transmission portion 312, and a corresponding slope that is in contact with the extrusion slope 315 is provided on the side of the side positioning portion 311, and a side elastic member 316 is provided on the side of the side transmission portion 312 away from the slope. The side elastic member 316 can be a spring or an elastic rod, etc., which has an elastic tendency to push the side positioning portion 311 to move along the first direction X so as to press the side positioning portion 311 against the extrusion slope 315.

[0093] By providing the side elastic member 316, the side positioning portion 311 can utilize the elastic force of the side elastic member 316 to move along the first direction X and press against the side of the first product 5. When the positioning needs to be released, the side transmission portion 312 moves upward along the second direction Z, and the extrusion slope 315 squeezes the side positioning portion 311, thereby pushing the side positioning portion 311 away from the first product 5 and squeezing the side elastic member 316. The side elastic member 316 will generate a greater elastic tendency to limit the sliding of the side positioning portion 311 and ensure that the side positioning portion 311 presses against the extrusion slope 315.

[0094] Optionally, the top positioning assembly 32 includes a top positioning portion 321 and a top transmission portion 322. The top positioning portion 321 is rotatably connected to the first space 21 and has a pressing head 323. The top transmission portion 322 is slidably connected to the fixture 2 and connected to the top positioning portion 321 to drive the top positioning portion 321 to rotate, thereby moving the pressing head 323 closer to or away from the top of the first product 5.

[0095] Specifically, a rotating rod 324 is provided at a position of the first space 21 away from the second space, and the top positioning portion 321 is fixed to the rotating rod 324 to achieve a rotational connection. A pressure head 323 protrudes outward from the upper side of the top positioning portion 321. The pressure head is plate-shaped and U-shaped. The lower side of the top positioning portion 321 is connected to the top transmission portion 322. The top transmission portion 322 can use a cylinder as a driving element to drive its sliding. The top transmission portion 322 and the top positioning portion 321 can be connected by a connecting rod assembly, so that the top transmission portion 322 can drive the top positioning portion 321 to rotate when sliding, or the top transmission portion 322 can directly push the top pressure portion to drive the top pressure portion to rotate.

[0096] When the first product 5 is placed in the first space 21, the top positioning portion 321 first rotates and leaves the first space 21 to release the first space 21 and ensure smooth entry of the first product 5. After the first product 5 enters, the top transmission portion 322 drives the top positioning portion 321 to rotate, so that the top positioning portion 321 drives the pressing head 323 to press against the top wall of the first product 5, thereby achieving positioning of the top side of the first product 5. By providing a sliding top transmission portion 322 and a rotating top positioning portion 321, sliding can be converted into rotation to achieve positioning of the first product 5, making the structural layout of the top positioning assembly 32 more compact, occupying less space, and being able to adapt to smaller first products 5, so as to achieve accurate positioning of small products.

[0097] Optionally, the top transmission part 322 slides along the third direction Y, the top positioning part 321 has a transmission notch 326 for partially inserting the top transmission part 322 , and the top positioning part 321 is provided with a top elastic member 325 to limit the rotation of the top positioning part 321 .

[0098] Specifically, the top positioning portion 321 is block-shaped, and the axis around which the rotating rod 324 rotates is the rotation axis. A top elastic member 325 is provided on the front side of the top positioning portion 321 , and the top elastic member 325 may be a spring or an elastic rod. When the top transmission part 322 is in the state of being pressed down, the top transmission part 322 will be in the state of being pressed down, so that the top transmission part 322 will be in the state of being pressed down.

[0099] By distributing the transmission notch 326 and the pressure head 323 on both sides of the rotating rod 324, and in this embodiment, the contact position between the top transmission part 322 and the transmission notch 326 is farther away from the axis of the rotating rod 324, thereby forming a longer force arm, the top transmission part 322 only needs a smaller driving force to drive the top positioning part 321 to rotate, and can also ensure that the positioning force applied by the top positioning part 321 is just enough to position the small product without damaging the product.

[0100] Reference Figure 6 and Figure 8 Optionally, the second positioning assembly includes a positioning seat 41 and a transmission member 42. The positioning seat 41 is slidably connected to the fixture 2 along the third direction Y and is used to carry the second product 6; the transmission member 42 is connected to the positioning seat 41 to drive the positioning seat 41 to slide so that the second product 6 approaches or moves away from the first product 5.

[0101] Specifically, a positioning block 43 is fixedly installed in the fixture 2. A slideway is provided in the positioning block 43 along the third direction Y. The slideway is slidably connected to the positioning seat 41. The positioning seat 41 partially protrudes from the top of the positioning block 43 to form a second space for receiving the second product 6. The positioning seat 41 can be plugged into and matched with the second product 6 to fix the second product 6 and expose the outer surface of the second product 6, so as to facilitate the bonding and assembly of the second product 6 with the first product 5. The transmission member 42 can be set on the lower side of the positioning seat 41, and a cylinder or the like can be used as a driving element to drive the transmission member 42 to move along the third direction Y. The transmission member 42 can thereby drive the positioning seat 41 to slide along the third direction Y. It should be understood that the transmission member 42 can also be driven by a motor in conjunction with a transmission structure such as a lead screw, and the present invention does not specifically limit this.

[0102] By setting a sliding positioning seat 41, it can position the second product 6 when receiving the second product 6, and can slide along the third direction Y under the drive of the transmission member 42 to drive the second product 6 to fit onto the first product 5 after gluing, so that the positioning of the second product 6 is simple and reliable, and the fitting with the first product 5 can be automatically completed, so as to improve the degree of automation of product bonding and assembly.

[0103] Optionally, the positioning seat 41 has a limiting elastic member 44 , and the limiting elastic member 44 has an elastic tendency to limit the sliding of the positioning seat 41 .

[0104] Specifically, the limiting elastic member 44 extends along the third direction Y. It can be a spring or an elastic rod or other structure. It can be compressed when the positioning seat 41 is away from the first product 5 to generate an elastic trend. When the first product 5 is completed with glue and the second product 6 needs to be fitted with the first product 5, the positioning seat 41 can approach the first product 5 under the action of the transmission member 42 and gradually release the limiting elastic member 44 to push the first product 5 and the second product 6 together to ensure a better bonding effect between the two.

[0105] Optionally, the second positioning assembly further includes a support seat 45 and a support elastic member 46. The support seat 45 is vertically slidably connected to the positioning seat 41 and can be inserted into the second product 6; the support elastic member 46 is connected to the support seat 45 to limit the support seat 45 from sliding in the vertical direction.

[0106] Specifically, the support seat 45 is in the shape of a long strip, and guide strips 47 are provided at both ends of its lower side. The guide strips 47 are inserted into the positioning seat 41 and are slidingly connected to the positioning seat 41. A supporting elastic member 46 is provided in the middle of the lower side of the support seat 45, and the supporting elastic member 46 can also be partially embedded in the interior of the positioning seat 41. A plug 48 protrudes upward on the top wall of the support seat 45. The plug 48 can be adapted to the internal shape of the second product 6. It can be fully inserted into the second product 6 and fit against the inner wall of the second product 6, thereby completing the fixation of the second product 6.

[0107] By setting the support seat 45 and the support elastic member 46, when the second product 6 is placed, the top of the support seat 45 is inserted into the second product 6, and when the second product 6 is installed, the support seat 45 can squeeze the support elastic member 46 to make the support seat 45 slide down, so that a certain buffer is formed when the second product 6 is inserted into the support seat 45, so as to reduce the possibility of the second product 6 being damaged during installation.

[0108] Optionally, multiple groups of first spaces 21 and second spaces can be distributed at intervals on the clamp 2, wherein each first space 21 is provided with a group of first positioning mechanisms 3, and each second space is provided with a group of second positioning mechanisms 4, and each first positioning mechanism 3 can be individually configured with a special driving element for driving, and similarly, each second positioning mechanism 4 can also be configured with a separate driving element for driving.

[0109] Reference Figure 4 and Figure 5 In this embodiment, four first positioning mechanisms 3 and four second positioning mechanisms 4 are provided. The four side positioning assemblies 31 are equipped with a common side positioning cylinder 317 as a driving element. The piston rod of the side positioning cylinder 317 extends and retracts in the vertical direction. The side connecting rod 318 and the four side transmission parts 312 are connected to the common side connecting rod 318. The side connecting rod 318 can abut against the piston rod of the side positioning cylinder 317. The four top positioning assemblies 32 are equipped with a common top positioning cylinder 327. The piston rod of the top positioning cylinder 327 extends and retracts in the third direction Y. The four top transmission parts 322 are connected to the common top connecting rod 328. The top connecting rod 328 abuts and cooperates with the piston rod of the top positioning cylinder 327.

[0110] Reference Figure 6 The four second positioning mechanisms 4 are jointly configured with a pushing cylinder 49, and the piston rod of the pushing cylinder 49 retracts and contracts along the third direction Y and abuts against a pushing rack 491 at the end of the piston rod. Four connecting columns 492 are provided on the pushing rack 491, and each connecting column 492 is plugged into and cooperates with a second positioning mechanism 4. An adjusting cylinder 493 can also be provided on the side of the pushing rack 491. The piston rod of the adjusting cylinder 493 retracts and contracts along the first direction X and abuts against the pushing rack 491 to push the pushing rack 491 and other structures to move in the first direction X. In order to improve the flexibility of adjustment, the adjusting cylinder 493 can also be replaced with a servo motor, and the position of the pushing rack 491 can also be adjusted in conjunction with the adjusting screw. The present invention does not make specific limitations on this.

[0111] By sharing the driving elements between multiple first positioning mechanisms 3 and multiple second positioning mechanisms 4, not only can space be further saved and the structure simplified, but it can also ensure that all the first positioning mechanisms 3 and all the second positioning mechanisms 4 operate synchronously, so that the clamp 2 can bond and assemble multiple groups of products at one time, further improving the processing efficiency of the products.

[0112] Reference Figure 9 Optionally, the fixture 2 is detachably connected to the base 1; the positioning device further includes a fixing base 23, a fixing rod 24, and a fixing drive 25. The fixing rod 24 is rotatably connected to the fixing base 23, and one end of the fixing rod 24 can press against the top wall of the fixture 2; the fixing drive 25 is connected to the other end of the fixing rod 24 to drive the fixing rod 24 to rotate.

[0113] Specifically, a plurality of guide posts can be spaced apart on the base 1, and the clamp 2 can be inserted into the guide posts to form a detachable connection between the clamp 2 and the base 1. The fixing seat 23 is U-shaped, and the middle portion of the fixing rod 24 is rotatably connected to the fixing seat 23. A notch is provided at the edge of the top wall of the clamp 2 to accommodate one end of the fixing rod 24. The other end of the fixing rod 24 is hinged to the output end of the fixed drive member 25. The fixed drive member 25 can be a cylinder or other type of drive element, which is not limited by the present invention. A hinged structure can be provided at the output end of the fixed drive member 25 to rotatably connect with the fixing rod 24.

[0114] After a group of products are bonded, the fixed drive 25 is operated to pull one end of the fixed rod 24 so that the fixed rod 24 rotates and disengages from the clamp 2. After the clamp 2 is removed from the base 1 and the residual glue is cleaned, the clamp 2 is installed on the base 1. The fixed drive 25 is operated to push the fixed rod 24 to rotate, so that the fixed rod 24 presses against the top wall of the clamp 2 to fix the clamp 2, so that the clamp 2 can be easily and quickly disassembled. In order to improve the fixing effect, a set of fixed seats 23, fixed rods 24 and fixed drive members 25 can be set at the four corners of the clamp 2. The specific number and position of the fixed seats 23, fixed rods 24 and fixed drive members 25 are not limited by the present invention.

[0115] Reference Figures 10 to 13 The dispensing device includes a machine 100, a mobile module 200, a loading device, a dispensing device 300, a pressure cap 400, and a positioning device as described above. The mobile module 200 is arranged on the machine 100. The positioning device is arranged on the mobile module 200, and the mobile module 200 is used to drive the positioning device to move to the loading position and the dispensing position; the loading device transports the first product 5 or the second product 6 into the positioning device at the loading position; the dispensing device 300 dispenses glue for the first product 5 in the positioning device at the dispensing position; the pressure cap 400 is placed on the top wall of the fixture 2 of the positioning device and covers the first product 5 and the second product 6.

[0116] Specifically, a protective cover is provided on the machine 100, and a dispensing space is formed inside the protective cover. The mobile module 200, the positioning device, the loading device and the dispensing device 300 are all located in the dispensing space. The mobile module 200 is a linear motor module, which can drive the positioning device to move along the second direction Z. A loading position is provided at the tail end of the mobile module 200, and two material trays 600 can be provided on both sides of the loading position to supply the first product 5 and the second product 6 respectively. The loading device can be a robot to carry the first product 5 and the second product 6. A material storage frame 500 can be provided on the side of the material tray 600. The robot can also carry the bonded products into the material storage frame 500. A dispensing position is provided in the middle of the mobile module 200. The dispensing device 300 can move along the third direction Y to the dispensing position to dispense glue to the first product 5. The specific structure of the dispensing device 300 can refer to the existing technology. This is not the core of the protection of this solution, so it will not be described here.

[0117] The pressing cover 400 is a plate-like structure that can be placed on the top wall of the positioning device and cover all of the first product 5 and the second product 6. A raised structure can be provided on the bottom wall of the pressing cover 400 to press against the first product 5 and the second product 6, thereby ensuring smooth bonding. A receiving seat 700 can be provided on the side of the movable module 200 to accommodate the pressing cover 400 for quick removal.

[0118] When assembling the first product 5 and the second product 6, first install the fixture 2 of the positioning device, then use the moving module 200 to drive the positioning device to the loading position, move the first product 5 into the first space 21 and use the first positioning mechanism 3 to position the first product 5, then the moving module 200 drives the positioning device to move to the gluing position, the gluing device 300 applies the glue on the surface of the first product 5, the moving module 200 drives the positioning device to move to the loading position, move the second product 6 into the second space and complete the positioning, and then use the second positioning mechanism 4 to push the second product 6 close to the first product 5, and move the pressure cover 400 onto the positioning device, squeeze the first product 5 and the second product 6, and then move the positioning device and the pressure cover 400 to the baking equipment for drying. After drying, the positioning device and the pressure cover 400 are moved onto the moving module 200 and removed from the pressure cover 400. The moving module 200 drives the positioning device to move to the loading position again, moves the completed assembled product away and re-loads and repeats the above process. Therefore, during the use of the dispensing equipment, the positioning device can automatically complete the positioning of the first product 5 and the second product 6 without manual intervention and multiple adjustments, thereby effectively saving the time spent on positioning small products, making the product bonding and assembly process less time-consuming, which is conducive to improving the overall processing efficiency. At the same time, the positioning accuracy can be guaranteed only after the equipment debugging is completed, ensuring the high quality of the bonding and assembly of batch products.

[0119] Reference Figures 14 to 16 Optionally, the fixture 2 has a locking notch 26, and the pressure cover 400 has a locking block 401 that is inserted into the locking notch 26. The dispensing device further includes a locking portion 261 and a locking actuator 262. The locking portion 261 is slidably connected to the locking notch 26 and can be engaged and locked with the locking block 401. The locking actuator 262 is used to push the locking portion 261 to slide, thereby engaging or disengaging the locking portion 261 with the locking block 401.

[0120] Specifically, the clamp 2 is provided with locking notches 26 on both the front and rear sides along the third direction Y, and the pressure cover 400 is provided with locking blocks 401 on both the front and rear sides. The side surfaces of the locking blocks 401 are provided with locking protrusions. A mounting sleeve is provided in the locking notch 26, and the locking portion 261 is slidably connected within the mounting sleeve along the third direction Y. In this embodiment, two locking portions 261 can be provided, and the locking block 401 can be inserted between the two locking portions 261. An opening can be provided on the side of the locking portion 261 near the locking block 401 to form an insertable engagement with the locking protrusion, thereby forming a snap-fit ​​engagement between the locking portion 261 and the locking block 401.

[0121] The locking driver 262 can be a pneumatic cylinder, whose driving end comprises two sliders capable of sliding in the first direction X. Each slider corresponds to a locking portion 261. A lever is provided on the side of the locking portion 261, extending through a mounting sleeve and forming a sliding engagement therewith. The sliders can be connected to the lever. It should be understood that the locking driver 262 can also be a servo motor, which can also drive the locking portion 261 in conjunction with a transmission structure such as a lead screw. The specific type of the locking driver 262 is not limited in this invention.

[0122] By providing the locking block 401 and the locking portion 261, when the pressing cover 400 is pressed onto the clamp 2, the locking block 401 is inserted into the locking notch 26. At this time, the locking driver 262 is actuated to drive the locking portion 261 to slide, so that the locking portion 261 engages with the locking block 401, thereby fixing the locking block 401 in the locking notch 26 and also fixing the pressing cover 400 to the clamp 2. To improve the fixing effect, the locking protrusion of the locking block 401 can be provided with an inclined surface so that when the locking protrusion and the locking portion 261 are inserted and engaged, they can form a squeeze, thereby compressing the locking block 401.

[0123] Optionally, the locking portion 261 is provided with a restoring elastic member 263 , and the restoring elastic member 263 has an elastic tendency to limit the sliding of the locking portion 261 .

[0124] Specifically, one end of the reset elastic member 263 is connected to the locking portion 261, and the other end is fixedly connected to the side wall of the locking notch 26, and the reset elastic member 263 can be a spring or elastic member rod structure, which extends along the third direction Y to slide the locking portion 261 at the upper limit value of the third direction Y.

[0125] When the locking portion 261 is opened by the locking drive member 262, the locking portion 261 can squeeze the reset elastic member 263, so that the reset elastic member 263 generates an elastic tendency to limit the sliding of the locking portion 261, and when the locking portion 261 is snapped into place with the locking block 401, the locking drive member 262 returns to its position, and the reset elastic member 263 can drive the locking portion 261 to reset so that the locking portion 261 is snapped into place with the locking block 401, and at this time, the reset elastic member 263 continues to maintain a certain elastic tendency to ensure that the locking portion 261 can maintain a snap fit with the locking block 401.

[0126] Optionally, the pressure cover 400 is slidably connected to the parts corresponding to the first product 5 and the second product 6 with a pressure block 402. One side of the pressure block 402 can be tightly pressed against the first product 5 and the second product 6, and the other side is provided with a pressing elastic part 403. The pressing elastic part 403 has an elastic tendency to limit the sliding of the pressure block 402.

[0127] Specifically, a mounting hole is provided on the bottom wall of the pressure cover 400, and a pressing elastic member 403 is arranged in the mounting hole. The pressing elastic member 403 extends along the first direction X, which can be a spring. A pressing block 402 is provided at the opening of the mounting hole. The pressing block 402 slides in conjunction with the mounting hole. The lower side surface of the pressing block 402 corresponds to the first product 5 and the second product 6, and the shape of the pressing block 402 is adapted to the pressing head 323 to ensure that the two do not interfere with each other.

[0128] By arranging a pressing block 402 on the pressing cover 400, after the pressing cover 400 is covered on the clamp 2, the pressing block 402 can be pressed tightly against the second product 6 and the first product 5. When the second product 6 is inserted into the support seat 45, the support seat 45 is provided with an elastic structure. Therefore, the pressing block 402 can press the second product 6 down to the position corresponding to the first product 5, and by arranging the pressing elastic member 403, an elastic tendency can be continuously generated on the pressing block 402, so that the pressing block 402 maintains the extrusion force on the first product 5 and the second product 6, so as to further improve the bonding effect of the products.

[0129] Reference Figure 17 The product assembly method is applied to the above-mentioned dispensing equipment, including:

[0130] Step S1: transport a first product into a first space and position both sides of the first product.

[0131] The positioning device is moved to the loading position by the linear motor module. A large number of first products are stored in a loading device. The robot can stably clamp the smaller first products and transport one first product to each first space. The first positioning mechanism is used to position both sides of the first product to quickly complete the positioning of the first product and expose the glue-coated surface of the first product.

[0132] Step S2: dispensing glue on the first product in the first space.

[0133] The linear motor module can move the positioning device containing the first product to the dispensing position. At this time, there is no product in the second space, and the dispensing device can dispense glue on the glue-coated surface of the first product within a sufficient space range.

[0134] Step S3: transport the second product into the second space and position it.

[0135] After the first product is coated with glue, the positioning device is moved to the loading position. At this time, the second product is transported to the second space and positioned so that the second product corresponds to the first product.

[0136] Step S4: Push the second product to fit the first product and squeeze and dry the first product and the second product to complete the assembly of the first product and the second product.

[0137] After completing the positioning of the second product, the second product can be pushed to fit the first product and the second product can be aligned with the first product using the pressure cover. Finally, the assembly can be completed by baking. Repeating the above steps S1 to S4 can complete the batch assembly of multiple products.

[0138] Through the above steps S1 to S4, when gluing and assembling small products, the first product is first moved and positioned and glued, and then the second product is moved for positioning and gluing, so that the first product and the second product are positioned respectively, and the positioning is achieved by using the corresponding spatial structure, so that the positioning can be completed once, thereby effectively saving the time spent on positioning, and ensuring high positioning accuracy, thereby improving product assembly efficiency and effectively ensuring the quality of the assembled products.
