Description

Technical Field

[0001] This invention relates to the field of assembling equipment into casings, and particularly to an automatic assembly device and an automatic assembly equipment. Background Technology

[0002] A stylus consists of a pen casing and a pen tip housed inside the casing. To reduce pen tip movement within the casing, the outer circumference of the pen tip is close to the inner cavity size of the casing, and glue is used to fix the gap between the pen tip and the inner wall of the casing, making it somewhat difficult to insert the pen tip into the casing. At the same time, an FPC (flexible printed circuit board) is attached to the outer surface of the pen tip to enhance the functionality of the stylus. The presence of the FPC further increases the difficulty of inserting the pen tip into the casing.

[0003] Specifically, in the relevant technology, a small tool called a pressure rod is used manually to install the pen refill. After the refill is applied with adhesive, the pressure rod pushes the refill to the stop position inside the pen shell to ensure that the refill is installed. During the manufacturing process, the following problems exist: First, the touch FPC is not tightly attached to the pen refill and interferes with the pen shell; Second, when the FPC head of the pen refill enters the opening of the inner cavity of the pen shell, the FPC is prone to curling and lifting; Third, the refill may leak adhesive; Fourth, the pen refill may not be properly assembled with the pen shell, resulting in the pen shell cracking.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0024] In the description of this invention, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0026] It should be noted that a stylus is an accessory for tablet computers and is often used in conjunction with tablet computers. Of course, some styluses are also used on laptops with touch screens. In theory, any device with a touch screen and stylus adapter software can use a stylus. A stylus consists of a pen tip and a pen casing. The pen tip is inserted into the pen casing. To prevent the pen tip from wobbling after insertion, the outer circumference of the pen tip is often designed to be close to the size of the inner cavity of the pen casing, making insertion somewhat difficult. The pen tip also needs to house various components, such as a battery. The larger the space occupied by the pen tip, the more space is available for these components, which can improve the pen tip's performance. However, a larger outer circumference of the pen tip further increases the difficulty of insertion. The outer circumference of the pen tip is also covered with an FPC (flexible printed circuit board), which can also interfere with the insertion process. Specifically: First, the FPC may not be properly attached to the pen tip, interfering with the pen casing; second, when the FPC tip enters the opening of the inner cavity of the pen casing, the FPC may curl or lift; third, there may be excess adhesive on the pen tip; fourth, the pen tip may not be properly assembled with the pen casing, leading to breakage of the pen casing.

[0027] Reference Figures 1 to 7 As shown, a first aspect of the present invention provides an automatic assembly device 1000, including an assembly component 100 and a pushing component 200. The assembly component 100 has a first chamber 110, a second chamber 120, and a dispensing port. The dispensing port is at least connected to the first chamber 110. The first chamber 110 and the second chamber 120 are sequentially connected along a first direction. The first chamber 110 has a first abutting surface 111 for abutting the outer peripheral surface of a columnar core, and the second chamber 120 has a second abutting surface 121 for abutting the outer peripheral surface of a columnar shell. A reference plane is defined perpendicular to the first direction, and the projection of the first abutting surface 111 onto the reference plane is located within the projection of the second chamber 120 onto the reference plane. The pushing component 200 has a pushing member 210 that is movable along the first direction to push the columnar core into the inner cavity of the columnar shell. The automatic assembly device 1000 satisfies: H≤R≤H+X. R: The distance between the first abutment surface 111 and the second abutment surface 121; H: The thickness of the columnar shell; X: The difference between the inner diameter of the columnar shell and the diameter of the columnar core.

[0028] In this embodiment, the columnar core is the pen refill, and the columnar shell is the pen casing. The pen refill and the pen casing have similar shapes, and the size of the pen refill is smaller than the size of the pen casing. The shape of the pen refill can be cylindrical, prismatic, or a combination of cylindrical and prismatic. The first contact surface 111 is contoured to the outer peripheral surface of the pen refill, and the second contact surface 121 is contoured to the outer peripheral surface of the pen casing.

[0029] The first chamber 110 is perforated or grooved to hold the pen refill and abut against its outer peripheral surface. When the outer peripheral surface of the pen refill abuts against the first abutting surface 111, the FPC on the outer peripheral surface of the pen refill is also compressed. The first abutting surface 111 provides pressure protection for the FPC, thereby preventing interference between the FPC and the pen casing. The first abutting surface 111 can be a single surface or multiple surfaces abutting together. The second chamber 120 is perforated or grooved to hold the pen casing and abut against its outer peripheral surface. The second abutting surface 121 can be a single surface or multiple surfaces abutting together. Both the first chamber 110 and the second chamber 120 can be perforated or grooved, or one can be perforated and the other grooved.

[0030] When the first chamber 110 is perforated, the dispensing port is located on the perforation wall of the first chamber 110 and connects the first chamber 110 to the outside. When the first chamber 110 is grooved, the dispensing port can be the groove opening of the first chamber 110, or the dispensing port can be located on the groove wall of the first chamber 110 and connect the first chamber 110 to the outside. The dispensing port allows the dispensing device 2000 to dispense glue onto the outer circumference of the pen refill. After the pen refill is inserted into the pen shell, the glue dispensed by the dispensing device 2000 will bond the pen refill to the pen shell, making the pen refill and pen shell connected as one unit and reducing pen refill movement.

[0031] The first contact surface 111 in the first chamber 110 restricts the axis of the pen refill, and the second contact surface 121 in the second chamber 120 restricts the axis of the pen shell. The distance between the first contact surface 111 and the second contact surface 121 satisfies: H≤R≤H+X. The axis of the pen refill will be basically aligned with the axis of the pen shell, so that the projection of the pen refill on the reference plane does not exceed the projection of the inner cavity of the pen shell on the reference plane. When the pen refill moves along the first direction, the pen refill is inserted into the inner cavity of the pen shell without interfering with the pen shell, thus achieving high-precision assembly between the pen refill and the inner cavity of the pen shell. In addition, it should be noted that the thickness of the pen shell can be uniform or non-uniform. When the thickness distribution of the pen shell is non-uniform, the distance distribution between the first bearing surface and the second bearing surface is also non-uniform. This distance distribution is basically consistent with the thickness distribution of the pen shell. However, the distance between the first bearing surface and the second bearing surface always satisfies: H≤R≤H+X.

[0032] Specifically, when R=H, the bottom surface of the pen refill is aligned with the bottom surface of the pen casing's inner cavity; when R=H+X, the top surface of the pen refill is aligned with the top surface of the pen casing's inner cavity; and when R=H+X / 2, the central axis of the pen refill is aligned with the central axis of the pen casing. The above figures do not consider the influence of errors; in actual manufacturing, the impact of errors should be further considered.

[0033] The push-in component 200 provides a pushing force, causing the pusher to push the pen refill into the pen case along a first direction, thereby assembling the pen refill into the inner cavity of the pen case. Specifically, the pusher 210 pushes the pen refill from the end of the pen refill furthest from the pen case.

[0034] In general, by limiting the distance between the first contact surface 111 and the second contact surface 121, the axes of the columnar core and the columnar shell can be basically coincident, or in other words, their axes are within the same concentricity error range. This allows the outer circumferential contour of the columnar core to align with the inner circumferential contour of the inner cavity of the columnar shell. Under the push of the pusher, the columnar core can be directly inserted into the columnar shell without interfering with the shell. By improving the alignment accuracy between the columnar core and the columnar shell, the assembly efficiency of the columnar core into the shell is improved.

[0035] Reference Figure 4 As shown, in some specific embodiments of the present invention, the assembly component 100 includes a stepped surface located between the first abutting surface 111 and the second abutting surface 121, wherein the first abutting surface 111, the stepped surface and the second abutting surface 121 are formed as an integral and continuous surface.

[0036] It is worth understanding that the first contact surface 111, the stepped surface, and the second contact surface 121 are directly integrally formed in the same component. The distance between the first contact surface 111 and the second contact surface 121 is fixed, and the processing error is small and the precision is high, which makes the assembly precision of the pen refill and the pen shell higher.

[0037] In other embodiments, the first contact surface 111 and the second contact surface 121 are respectively provided on the two components, and the two components are spliced ​​together as one unit along the first direction, or the two components are spaced apart along the first direction.

[0038] Reference Figure 4 As shown, in some specific embodiments of the present invention, the fan-shaped angle range corresponding to the projection of the first contact surface 111 onto the reference plane is α, and the automatic assembly device 1000 satisfies: 180°<α≤360°, so as to cover more than half of the outer peripheral surface of the columnar core. And / or, the sector angle range corresponding to the projection of the second contact surface 121 onto the reference plane is β, and the automatic assembly device 1000 satisfies: 180°<β≤360°, so as to cover more than half of the outer peripheral surface of the columnar shell.

[0039] It is worth understanding that when the first abutting surface 111 covers more than half of the outer peripheral surface of the pen refill, the first abutting surface 111 will limit the pen refill radially, preventing the pen refill from moving radially. This improves the pressure holding effect of the first abutting surface 111 on the FPC and improves the movement accuracy of the pen refill. Similarly, the second abutting surface 121 limits the pen housing radially, preventing the pen housing from moving radially. This results in less radial offset between the pen refill and the pen housing during the insertion of the pen refill into the pen housing, and higher relative positional accuracy between the two, thus improving the assembly accuracy of the pen refill insertion into the pen housing.

[0040] In this embodiment, the first abutment surface 111 is arc-shaped, i.e., 180° < α < 360°, to cover more than half of the outer peripheral surface of the columnar core. The first abutment surface 111 has a notch, which forms an adhesive channel. The adhesive outlet and the adhesive channel are connected sequentially along the first direction, making it difficult for the adhesive coated on the outer peripheral surface of the pen core to adhere to the first abutment surface 111, thus reducing accuracy. Specifically, the adhesive channel can be a through hole connecting the first chamber 110 to the outside, or it can be a sealed space formed at the top of the first chamber 110. The size of this sealed space needs to be larger than the size of the outer peripheral surface of the pen core after the adhesive is applied. At the same time, the arc-shaped first abutment surface 111 is easier to process than the annular first abutment surface 111, and the processing accuracy is easier to control, resulting in higher accuracy. The second abutment surface 121 is also arc-shaped, 180° < β < 360°, making the processing of the second abutment surface 121 even more convenient.

[0041] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the assembly component 100 includes a first component 130, a second component 140, and a third component 150 arranged sequentially along a first direction. The first chamber 110 includes a first sub-cavity 112 and a second sub-cavity 113 connected sequentially along the first direction. The first sub-cavity 112 is used to place at least a portion of the columnar core, and the second sub-cavity 113 is provided with a first abutting surface 111. The second chamber 120 includes a third sub-cavity 122 and a fourth sub-cavity 123 connected sequentially along the first direction. The third sub-cavity 122 is provided with a second abutting surface 121, and the fourth sub-cavity 123 is used to place at least a portion of the columnar shell. The first component 130 has the first sub-cavity 112, the second component 140 has the second sub-cavity 113 and the third sub-cavity 122, and the third component 150 has the fourth sub-cavity 123. The first component 130, the second component 140, and the third component 150 are each independent components.

[0042] It is worth understanding that the second component 140 has a second cavity 113 and a third cavity 122, as well as a first abutment surface 111 and a second abutment surface 121. The second component 140 has high machining accuracy requirements. On the other hand, the first cavity 112 of the first component 130 is used to place the columnar core, and the fourth cavity 123 of the third component 150 is used to place the columnar shell. The machining accuracy requirements of the first component 130 and the third component 150 are lower than those of the second component 140, which reduces the overall machining accuracy requirements of the assembly component 100, reduces the machining difficulty, and saves machining costs.

[0043] In this embodiment, the first cavity 112 of the first component 130 is groove-shaped, and the fan-shaped angle corresponding to the projection of the first cavity 112 onto the reference plane is less than 180°. The pen refill can be directly inserted into the first cavity 112 from the groove opening, making pen refill placement more convenient. The fourth cavity 123 of the third component 150 is also groove-shaped, and the fan-shaped angle corresponding to the projection of the fourth cavity 123 onto the reference plane is also less than 180°. The tail end of the pen shell is first pre-inserted into the third cavity 122 of the second component 140, and then the second component 140 is installed between the third component 150 and the second component 140. The other end of the pen shell is located in the fourth cavity 123 of the third component 150. The end of the third component 150 facing the first component 130 is located in the mounting cavity 182, which is used to engage the second component 140. The second cavity 113 of the second component 140 has a chamfer at the end away from the third cavity 122. The chamfer guides the pen refill to enter, making it easier for the pen refill to enter. The FPC on the outer periphery of the pen refill is also guided, making it easier to enter the second cavity 113 and less likely to curl or peel.

[0044] The dispensing port is connected to the first cavity 112. When the first cavity 112 is groove-shaped, the groove of the first cavity 112 directly forms the dispensing port, which has a larger area and makes dispensing more convenient. Specifically, the first component 130 includes a first region, a second region, and a third region arranged sequentially along a first direction. The height of the second region is lower than that of the first and third regions. The sector angle corresponding to the projection of the first cavity 112 in the second region onto the reference plane is also lower than that corresponding to the projection of the first and third regions onto the reference plane. Furthermore, the first cavity 112 in the second region protrudes from the surface of the first component 130 in the second region, making the first cavity 112 higher. When applying glue in the second region, the sector angle corresponding to the projection of the first cavity 112 onto the reference plane is smaller, and more of the outer peripheral surface of the pen refill is exposed, making it easier to position and apply glue to the pen refill. In addition, since the first cavity 112 is higher, when glue drips onto the surface of the first component 130 in the second region, the glue is less likely to flow into the first cavity 112, making it easier to clean up the glue and also making it easier to remove the pen refill from the first cavity 112.

[0045] The third component 150 also includes a fourth region, a fifth region, and a sixth region arranged sequentially along the first direction. The height of the fifth region is lower than that of the fourth and sixth regions. The sector angle corresponding to the projection of the fourth cavity 123 in the fifth region onto the reference plane is also lower than that corresponding to the projection of the fourth and sixth regions onto the reference plane. Furthermore, the fourth cavity 123 in the fifth region protrudes from the surface of the third component 150 in the fifth region, making it convenient to pick up and put away the pen shell.

The control element is configured to: after the detection device 300 detects that the columnar core has moved to a first preset position, control the drive source 250 to drive the pushing element 210 to move in a second direction opposite to the first direction, so as to move away from the second chamber 120.

[0048] It should be noted that the first preset position refers to the preset position where the pen refill is fully inserted into the pen casing.

[0049] It is understandable that when the pen refill moves to the first preset position, the pen refill is fully inserted into the pen case. The through hole detection device 300 detects the position of the pen refill and resets it through the control component, so that the push-in component 210 returns to the initial position, making it easier to place the next pen refill to be assembled, making the automated operation more convenient.

[0050] In this embodiment, the detection device 300 includes a sensor, and the first component 130 is provided with a detection channel communicating with the first cavity 112. The sensor is disposed in the detection channel to detect the pen refill in the first cavity 112. Specifically, the detection channel is communicating with the bottom surface of the first cavity 112, or it can be communicating with the side surface of the first cavity 112.

[0051] In some other implementations, the detection channel may also be connected to the second cavity 113 of the second component 140; or, when the first cavity 110 is groove-shaped, the sensing element is disposed outside the first cavity 110 and facing the pen refill inside the first cavity 110.

[0052] Reference Figure 6 As shown, in some specific embodiments of the present invention, the second chamber 120 is configured to restrict the movement of the cylindrical shell along a first direction during the process of the cylindrical core being pushed into the cylindrical shell; or, the assembly assembly 100 further includes a first stop, which is configured to restrict the movement of the cylindrical shell along a first direction during the process of the cylindrical core being pushed into the cylindrical shell.

[0053] It is understandable that during the process of inserting the pen refill into the pen case, the pen case is limited along the first direction. When the pen refill moves along the first direction, the pen case cannot move along the first direction, so that the pen refill can be fully inserted into the inner cavity of the pen case, completing the assembly of the pen refill and the pen case, thus solving the problem of the pen refill and pen case not being properly assembled.

[0054] In this embodiment, refer to Figure 6 As shown, the second chamber 120 is provided with a stop wall 124 at the end away from the first chamber 110. The stop wall 124 stops the first end of the pen shell (the writing end). The stop wall 124 is also provided with a clearance hole for the pen tip of the pen refill to be inserted. The clearance hole can be a through hole or a blind hole.

[0055] In other embodiments, the movement of the pen shell along the first direction can be stopped by the inner peripheral wall of the second chamber 120; or a movable first stop can be provided at the end of the second chamber 120 away from the first chamber 110. When a stop is needed, the first stop moves and abuts against the first end of the pen shell, and when a stop is not needed, the first stop is misaligned with the second chamber 120 or moves away from the second chamber 120 along the first direction.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the assembly component 100 includes an assembly plate 160 and a fixing cover 170. One side of the assembly plate 160 is provided with a shell placement groove, and a second chamber 120 is formed in the shell placement groove. The fixing cover 170 can cover and fix the groove opening of the shell placement groove to limit the columnar shell in the shell placement groove. The push-in member 210 is provided with a protruding snap-fit ​​positioning part 211 on the side facing the second chamber 120. The snap-fit ​​positioning part 211 can snap onto the tail end of the columnar core.

[0057] It is understandable that by fixing the cap 170 to the opening of the shell placement groove, the pen shell is locked in the shell placement groove, thereby restricting the radial movement of the pen shell. During the process of inserting the pen refill into the pen shell in the first direction, the radial offset of the pen shell is less, and the positional accuracy of the pen shell is higher. The pen refill is fixed at the tail end by the locking positioning part 211, thereby restricting the radial movement of the pen refill. The positional accuracy of the pen refill is higher, so that the pen refill can be stably inserted into the pen shell in the first direction, improving the assembly accuracy.

[0058] In this embodiment, refer to Figure 1 As shown, the fixing cover 170 is located on one side of the shell placement groove and is rotatably connected to the assembly plate 160, rotating toward the opening of the shell placement groove. The assembly plate 160 has a snap-fit ​​on the opposite side of the shell placement groove. When the fixing cover 170 is closed onto the opening of the shell placement groove, the fixing cover 170 is engaged in the snap-fit, thus fixing the fixing cover 170 to the opening of the shell placement groove. (Refer to...) Figure 2 As shown, the snap-fit ​​positioning part 211 is a columnar protrusion, and the end of the pen refill is provided with an annular groove. The columnar protrusion can be snapped into the annular groove to realize the snap-fit ​​positioning part 211 and the end of the pen refill.

[0059] In other embodiments, the assembly plate 160 has snap-fit ​​fasteners on both sides of the second side, and the two sides of the fixing cover 170 are respectively snapped into the two snap-fit ​​fasteners; or, the fixing cover 170 is located on one side of the shell placement groove and is rotatably connected to the assembly plate 160, and the other side of the fixing cover 170 is locked to the other side of the shell placement groove by a pin. The snap-fit ​​positioning part 211 may also be an annular protrusion, or other structures corresponding to the shape of the pen refill tip.

[0060] Furthermore, when the first contact surface 111 is located at the beginning of the pen refill and covers more than half of the outer circumference of the pen refill, and the locking and positioning part 211 limits the end of the pen refill, both ends of the pen refill along the first direction are fixed. During the pushing process of the pusher 210, the pen refill moves along the first direction with high movement accuracy. When the second contact surface 121 is located at the end of the pen shell and covers more than half of the outer circumference of the pen shell, and the fixing cover 170 is closed on the outer circumference of the beginning of the pen shell or the outer circumference of the middle of the pen shell, both ends of the pen shell along the first direction are also fixed. The relative positional accuracy between the pen refill and the pen shell is high, further improving the assembly accuracy.

[0061] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the push-in component 200 further includes a second stop 220, which is disposed in the moving path of the push-in component 210; the second stop 220 is configured to limit the moving speed of the push-in component 210 along the first direction when the columnar core moves to the second preset position.

[0062] It should be noted that the second preset position refers to the position where the pen refill is about to be inserted into the pen case, but there is a certain distance between it and the first preset position.

[0063] It is understandable that when the pen refill moves to the second preset position, the second stop 220 pushes the stop insert 210 and reduces the moving speed of the insert 210, so that the insert 210 inserts the pen refill into the pen case at a lower speed, avoiding excessive pushing force that could cause collision damage to the pen refill. Specifically, ideally, during the process of the pen refill moving from the second preset position to the first preset position, the speed of the insert 210 is reduced to a low speed or even to zero, and when the detection device 300 detects that the pen refill is in the first preset position, the insert 210 resets in a second direction opposite to the first direction.

[0064] In this embodiment, refer to Figure 1 and Figure 2 As shown, the pushing assembly 200 includes a pushing member 210, a buffer member 230, a transmission member 240, and a drive source 250. The drive source 250 is driveably connected to the transmission member 240. The buffer member 230 is arranged along a first direction. The pushing member 210 is connected to the side of the transmission member 240 facing the second chamber 120 through the buffer member 230. When the pushing member 210 is stopped by the second stop member 220, the pushing member 210 compresses the buffer member 230, and the buffer member 230 absorbs kinetic energy, thereby reducing the moving speed of the pushing member 210. Specifically, the buffer 230 includes a guide rod and a spring, both arranged along the first direction. The push-in member 210 includes a push-in plate and an abutment plate, with the abutment plate connected to the push-in plate. The push-in member 210 is located at the end of the first chamber 110 away from the second chamber 120. The abutment plate is connected to one end of the guide rod. The other end of the guide rod slides through the transmission member 240. The elastic member is sleeved on the outer circumferential surface of the guide rod and is located between the abutment plate and the transmission member 240.

[0065] As another implementation, the buffer 230 can also be a buffer pad with a large elastic displacement.

[0066] Furthermore, the push-in assembly 200 also includes a guide member 260, which is disposed along a first direction. The push-in member 210 is guided and connected to the guide member 260. The guide member 260 guides the movement of the push-in member 210, enabling the push-in member 210 to move smoothly along the first direction, thereby improving the stability and accuracy of the push-in member 210's movement along the first direction. Specifically, the guide member 260 is a slide rail, and the push-in member 210 is slidably connected to the slide rail via a slider.

[0067] Reference Figure 5 and Figure 7 As shown, in some specific embodiments of the present invention, the automatic assembly device 1000 further includes: a base 180, the base 180 having a mounting surface 181 and a mounting cavity 182, the mounting surface 181 having a sliding groove along a first direction, the sliding groove communicating with the mounting cavity 182, the assembly component 100 being disposed on the mounting surface 181, and the push-in component 200 including a transmission component 240 and a drive source 250, the drive source 250 being disposed in the mounting cavity 182, the transmission component 240 passing through the sliding groove and drivingly connecting the drive source 250 and the push-in component 210.

[0068] It is understandable that by concealing the drive source 250 through the mounting cavity 182 within the base 180, the appearance of the automatic assembly device 1000 is made more aesthetically pleasing, while also preventing the drive source 250 from being interfered with by external components, thus making its use safer. In this embodiment, the guide 260 and the assembly plate 160 are both disposed on the mounting surface 181 along the first direction.

[0069] Reference Figure 5 As shown, in some specific embodiments of the present invention, the automatic assembly device 1000 further includes: two sets of assembly components 100 arranged side by side and spaced apart; the pushing component 200 includes two pushing members 210 and a transmission member 240 connecting the two pushing members 210, the transmission member 240 being located between the two assembly components 100, one pushing member 210 corresponding to one assembly component 100, so as to push the columnar core in the corresponding assembly component 100 into the inner cavity of the columnar shell.

[0070] It is worth understanding that one transmission component 240 connects two push-in components 210, enabling the transmission component 240 to drive both push-in components 210 to move in the first direction at one time, thus increasing the movement efficiency of the transmission component 240. Furthermore, the transmission component 240 is located between the two assembly components 100, that is, between the two push-in components 210. When the transmission component 240 applies a moving force to the two push-in components 210 respectively, the force on the transmission component 240 is more balanced, making it more reliable for long-term use.

[0071] In this embodiment, the two assembly components 100 are symmetrically distributed about the transmission component 240, and the two push-in components 210 are also symmetrically distributed about the transmission component 240.

[0072] Reference Figure 1 As shown, a second aspect of the present invention provides an automatic assembly device, comprising: an automatic assembly apparatus 1000 and a dispensing apparatus 2000 according to a first aspect of the present invention, wherein the dispensing apparatus 2000 is used to dispense adhesive into a columnar core in a first chamber 110 through a dispensing port.

[0073] It is worth understanding that by automatically dispensing the pen refill with glue using the dispensing device 2000, and then automatically assembling the pen refill and pen shell using the automatic assembly device 1000 in the first aspect embodiment, the automatic glue dispensing of the pen refill and the automatic assembly of the pen refill and pen shell are realized, resulting in a higher degree of automation and further improving the assembly efficiency of the pen refill and pen shell.

[0074] Reference Figure 8 As shown, in some specific embodiments of the present invention, the automatic assembly equipment further includes: a moving device 3000, a dispensing device 2000, and a control unit. The moving device 3000; at least one of the dispensing device 2000 and the automatic assembly device 1000 is connected to the moving device 3000. The dispensing device 2000 includes a visual recognition element 2100 and a dispensing component 2200 parallel to the visual recognition element 2100. The dispensing component 2200 is used to dispense glue onto the columnar core, and the visual recognition element 2100 is used to acquire image information of the columnar core. The control unit is electrically connected to the dispensing device 2000 and the moving device 3000. 00; The control unit is configured to: obtain the position of the columnar core based on the image information acquired by the vision recognition unit 2100; when the columnar core is located at the dispensing position, control the moving device 3000 to drive one of the dispensing unit 2200 and the automatic assembly device 1000 to move relative to the other, and control the dispensing unit 2200 to perform the dispensing operation; and the control unit is also configured to: after the dispensing unit 2200 performs the dispensing operation, determine whether the dispensing position of the columnar core is incorrect based on the image information acquired by the vision recognition unit 2100; when the dispensing position of the columnar core is correct, control the pusher 210 to perform the push-in operation.

[0075] It is worth noting that by using the visual recognition component 2100 for positioning, the dispensing component 2200 achieves higher dispensing accuracy. Furthermore, the visual recognition component 2100 can automatically identify erroneous dispensing and whether there are errors in the dispensing position, effectively preventing pen refill leakage and intercepting it in a timely manner.

[0076] In this embodiment, the moving device 3000 includes an X-axis moving component 3100 capable of moving along the X-axis direction, a Y-axis moving component 3200 capable of moving along the Y-axis direction, and a Z-axis moving component 3300 capable of moving along the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other, wherein the Y-axis direction is in the same direction as the first direction. The Y-axis moving component 3200 is connected to the automatic assembly device 1000, enabling the automatic assembly device 1000 to move along the Y-axis. The Z-axis moving component 3300 is connected to the dispensing device 2000, and the X-axis moving component 3100 is connected to the Z-axis moving component 3300, enabling the dispensing device 2000 to move along both the X-axis and Z-axis directions.

[0077] Specifically, the automatic assembly of the pen refill and pen casing includes the following steps: First, product loading: In the loading area, the pen casing is first loaded into the second chamber 120 of the automatic assembly device 1000, and then the pen refill is loaded into the first chamber 110 of the automatic assembly device 1000; Second, product dispensing and inspection: First, after the sensor detects that the pen refill loading is complete, the automatic assembly device 1000 moves from the loading area to the operating area via the Y-axis moving component 3200. The vision recognition component 2100 acquires the X-axis and Y-axis coordinates of the automatic assembly device 1000 and automatically adjusts the automatic assembly device 1000. The X and Y coordinates are the same as those of the dispensing component 2200. Then, the dispensing component 2200 performs the dispensing operation. After the dispensing is completed, the visual recognition component 2100 identifies whether the dispensing position of the pen refill is incorrect. If there is an error, the process is stopped; if there is no error, the next process continues. In the third step, the pen refill is automatically pushed. After the visual recognition component 2100 identifies that the dispensing position is correct, the control component controls the pusher 210 to move along the first direction to push the pen refill into the inner cavity of the pen shell. After the sensing component senses that the pen refill has moved to the first preset position, the pusher 210 retracts and resets along the second direction. In the fifth step, the assembled pen is taken out.

[0078] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
