[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," and "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0022] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0023] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0024] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.
[0025] In the chip component industry, packaging and tape-and-reel packaging equipment widely uses direct vibration modules for feeding. Since direct vibration modules can only feed continuously, while related equipment usually requires single-piece feeding, direct vibration modules need to be used in conjunction with separation mechanisms to separate continuously fed products into single-piece products.
[0026] The separation mechanism in related technologies uses an electromagnet as a power source, which drives the separation needle to move repeatedly. When the separation needle extends, it blocks the product, thus separating it. However, the separation needle's reciprocating motion relative to the separation base for extended periods can cause it to wear down or deform, necessitating frequent replacements.
[0027] Because the separating needle is fitted onto the electromagnet's drive rod and secured with screws, and its tip also passes through the needle hole of the separating base, replacing the separating needle requires first removing the separating base to pull the needle tip out of the needle hole. Then, the screws on the separating needle must be loosened, the old separating needle removed from the drive rod, and a new one installed. Finally, the screws are tightened and the separating base is reinstalled. The process of replacing the separating needle is complex, difficult to debug after installation, and time-consuming, leading to a decrease in the operating rate of the tape-and-reel equipment.
[0028] Furthermore, because the separation needle and the drive rod are rigidly connected, when the products are separated asynchronously, the separation needle will press against the product, which can easily cause the product to crack or be scratched.
[0029] Based on the above analysis, this application provides a separation mechanism that can not only shorten the time required to replace the separation needle, but also improve the durability of the separation needle and reduce the number of replacements, thereby improving the uptime of the tape-and-reel equipment.
[0030] The technical solution of this application will be described below with reference to the embodiments and accompanying drawings.
[0031] Please refer to the above as well. Figure 1 and Figure 2 This application discloses a separation mechanism 100, including a first mounting base 101, a needle assembly 102, a drive assembly 103, and a locking member 104.
[0032] A needle assembly 102 is movably mounted on a first mounting base 101 and configured to receive a release needle 105. A drive assembly 103 is mounted on the first mounting base 101 and connected to the needle assembly 102 to drive the needle assembly 102 to move linearly back to its original position. A locking member 104 is mounted on the needle assembly 102.
[0033] The locking member 104 has an unlocked state and a locked state. In the unlocked state, the needle assembly 102 is configured to engage with the separating needle 105 with a clearance, allowing the separating needle 105 to be withdrawn or inserted into the needle assembly 102. In the locked state, the locking member 104 is configured to secure the needle assembly 102 and the separating needle 105, causing the separating needle 105 to move together with the needle assembly 102.
[0034] The needle kit 102 and locking member 104 of this application constitute a quick-change structure for the separation needle 105, which can not only shorten the time required to replace the separation needle 105, but also improve the durability of the separation needle 105, reduce the number of replacements, and thus improve the equipment uptime.
[0035] Specifically, this application sets up a needle assembly 102 to house the separation needle 105, and a drive assembly 103 is connected to the needle assembly 102 to drive the needle assembly 102 to move linearly back to the reset position. In this way, the separation needle 105 can move linearly back to the reset position along with the needle assembly 102, thereby realizing the product separation function.
[0036] Based on this, the needle assembly 102 of this application is provided with a locking member 104. The locking member 104 has an unlocked state and a locked state. In the locked state, the locking member 104 secures the needle assembly 102 and the separating needle 105. In this application, the term "secures" means that the locking member 104 connects the needle assembly 102 and the separating needle 105 together, thereby limiting the relative displacement of the needle assembly 102 and the separating needle 105 so that the separating needle 105 moves together with the needle assembly 102. The drive assembly 103 drives the separating needle 105 to move linearly back to its original position via the needle assembly 102, thereby achieving product separation.
[0037] In the unlocked state, the relationship between the locking member 104 and the needle assembly 102 is, for example, clearance fit or separation, so that the needle assembly 102 and the separating needle 105 are clearance fit, and the separating needle 105 can be pulled out or inserted into the needle assembly 102, so as to quickly disassemble and replace the separating needle 105, shorten the time spent replacing the separating needle 105, reduce the difficulty of replacing the separating needle 105, and help improve the utilization rate of the tape feeding equipment.
[0038] In some embodiments, please refer to Figure 1 and Figure 2The separation mechanism 100 also includes a separation needle 105 for separating products. Furthermore, the separation needle 105 is an elastic needle. The tip 1051 of the elastic needle is elastic, and the impact force on the product when the tip 1051 is protruded is further reduced, which helps protect the product's structure and is suitable for separating fragile products, such as ceramic products.
[0039] In some embodiments, the locking member 104 is sleeved on the needle assembly 102. In the unlocked state, the locking member 104 is in clearance engagement with the needle assembly 102, so that the needle assembly 102 is in clearance engagement with the separating needle 105. In the locked state, the locking member 104 grips the needle assembly 102, so that the needle assembly 102 grips the separating needle 105.
[0040] Furthermore, such as Figure 3 As shown, a slit 1021 is provided at one end of the needle assembly 102, and a locking member 104 is sleeved on the portion of the needle assembly 102 with the slit 1021. In the locked state, the locking member 104 contracts radially, causing the width of the slit 1021 to narrow, and the portion of the needle assembly 102 with the slit 1021 is configured to hold the separating needle 105.
[0041] In this embodiment, the portion of the needle assembly 102 with the slit 1021 is more easily deformed than other portions of the needle assembly 102, thus making it easier to radially contract. Specifically, when the locking member 104 switches to the locked state, the slit 1021 deforms and narrows, causing the portion of the needle assembly 102 with the slit 1021 to radially contract and grip the separating needle 105. At this time, the fit between the needle assembly 102 and the separating needle 105 is, for example, an interference fit. When the locking member 104 switches to the unlocked state, the width of the slit 1021 returns to its original position, allowing the needle assembly 102 and the separating needle 105 to have a clearance fit. In this way, the locking member 104 can quickly fasten and disassemble the needle assembly 102 and the separating needle 105.
[0042] In this application, the term "clamping" refers to the radially inward compressive pressure exerted by the containing element, causing the containing element (e.g., locking element 104) to adhere to the contained element (e.g., needle assembly 102). Relative sliding is restricted by the friction between their contact surfaces. The fit between the separating needle 105 and the needle assembly 102 is, for example, an interference fit. Therefore, when the needle assembly 102 clamps the separating needle 105, the needle assembly 102 and the separating needle 105 are fixed by friction rather than a rigid connection. This helps reduce the impact force on the product when the separating needle 105 performs its separating function, thereby improving the durability of the separating needle 105, reducing replacement frequency, and increasing the uptime of the tape-tapping equipment.
[0043] For example, the needle assembly 102 is a metal sleeve, and the slit 1021 is a strip-shaped slit 1021 extending to the end of the metal sleeve. The locking element 104 is a clamp. When the locking screw 1041 tightens the clamp, the clamp switches to the locked state, the clamp tightens radially, and the strip-shaped slit 1021 deforms and narrows in width. When the locking screw 1041 loosens the clamp, the clamp switches to the unlocked state, and the width of the strip-shaped slit 1021 returns to its original position, allowing the metal sleeve to engage with the separating needle 105.
[0044] As other examples, locking elements may also include pins, snaps, elastic retaining rings, clamping flanges, or expansion sleeves.
[0045] In some embodiments, such as Figure 4 As shown, the separation mechanism 100 also includes a linkage 106, and the drive assembly 103 includes a power source 1031 and a drive member 1032. The drive member 1032 passes through the power source 1031, and the linkage 106 is connected between the drive member 1032 and the needle assembly 102, so that the power source 1031 drives the needle assembly 102 to reciprocate linearly along the first direction Z.
[0046] In this way, the drive unit 1032 and the needle assembly 102 can be linked together. Furthermore, the drive unit 1032 and the needle assembly 102 can be arranged coaxially, that is, the drive unit 1032 and the needle assembly 102 can be linked in parallel.
[0047] For example, the linkage 106 can be a linkage block, linkage rod, or linkage plate. The drive assembly 103 can be an electromagnet assembly, a cylinder assembly, or an electric push rod assembly.
[0048] Furthermore, such as Figure 4 As shown, along the first direction Z, the linkage 106 can be displaced relative to the drive 1032 to adjust the stroke of the needle assembly 102 when it is ejected, thereby adjusting the position of the needle tip 1051 when the separation needle 105 is ejected, so that the needle tip 1051 protrudes out of the needle hole and blocks the product, thereby achieving product separation.
[0049] Specifically, when the first direction Z is vertical, the linkage 106 is adjusted by moving upward (away from the first mounting base 101), which makes the height of the needle tip 1051 relative to the first mounting base 101 higher when the separating needle 105 is ejected. Conversely, when the linkage 106 is adjusted by moving downward, the height of the needle tip 1051 relative to the first mounting base 101 becomes lower when the separating needle 105 is ejected.
[0050] Furthermore, such as Figure 4As shown, the separation mechanism 100 also includes a first stop 107. The first stop 107 is disposed on the linkage 106 and can abut or separate from the drive member 1032. When the first stop 107 abuts against the drive member 1032, the drive member 1032 and the linkage 106 are fixedly connected. When the first stop 107 separates from the drive member 1032, the linkage 106 and the drive member 1032 are in clearance fit, so that the linkage 106 can be adjusted relative to the drive member 1032 along the first direction Z displacement. This application realizes the installation and disassembly of the linkage 106 and the drive member 1032 through the first stop 107, which has the advantage of convenient operation.
[0051] Furthermore, such as Figure 4 As shown, the separation mechanism 100 also includes a second stop 108. The second stop 108 is disposed on the linkage 106 and can abut or separate from the needle assembly 102. When the second stop 108 abuts against the needle assembly 102, the needle assembly 102 is fixedly connected to the linkage 106. When the second stop 108 separates from the needle assembly 102, the linkage 106 and the needle assembly 102 are in clearance fit. This application realizes the installation and disassembly of the linkage 106 and the needle assembly 102 through the second stop 108, which has the advantage of convenient operation.
[0052] Optionally, such as Figure 4 As shown, the needle assembly 102 is provided with a snap-fit recess 1022. One end of the linkage member 106 is snapped into the snap-fit recess 1022 so that the linkage member 106 is positioned on the needle assembly 102 and the linkage member 106 and the needle assembly 102 move together.
[0053] For example, the second stop 108 can be a stop screw, a stop pin, or a stop pin. The first stop 107 can be arranged radially along the drive member 1032, and the second stop 108 can be arranged radially along the needle assembly 102.
[0054] In some embodiments, refer to Figure 5 The separation mechanism 100 also includes a pre-pressure adjustment component 109, a second mounting base 110, and an elastic component 111.
[0055] The preload adjustment component 109 is connected to the end of the drive component 1032 away from the linkage component 106, along the first direction Z, and the preload adjustment component 109 can be adjusted relative to the drive component 1032.
[0056] The second mounting base 110 is disposed on the first mounting base 101, along the first direction Z, and is disposed opposite to the first mounting base 101.
[0057] The elastic element 111 is connected between the preload adjustment element 109 and the second mounting base 110. The power source 1031 is an electromagnet. When the electromagnet is energized, the driving element 1032 moves in a direction close to the elastic element 111, compressing the elastic element 111. When the electromagnet is de-energized, the elastic element 111 rebounds, causing the driving element 1032 to reset. Thus, the elastic element 111 serves to reset the driving element 1032.
[0058] More specifically, along the first direction Z, the drive member 1032 passes through the power source 1031 and extends to both ends of the power source 1031, and the linkage member 106 and the preload adjustment member 109 are respectively connected to both ends of the drive member 1032.
[0059] The following example, using an electromagnet as the power source 1031, illustrates the function of the elastic element 111: When the electromagnet is energized, the drive member 1032 retracts along the direction close to the elastic member 111, compressing the elastic member 111, and drives the needle assembly 102 and the separating needle 105 to retract together via the linkage member 106. When the electromagnet is de-energized, the elastic member 111 returns to its original position, thereby lifting the drive rod, and the drive member 1032 drives the needle assembly 102 and the separating needle 105 to extend together via the linkage member 106. In this way, the separating needle 105 achieves a reciprocating motion of extension and retraction.
[0060] In order to allow the needle tip 1051 of the separating needle 105 to retract into the needle hole when the separating needle 105 retracts, the preload adjustment member 109 can be adjusted relative to the drive member 1032 along the first direction Z to adjust the stroke of the drive member 1032 when it retracts, thereby adjusting the position of the needle tip 1051 of the separating needle 105 when it retracts, so that when the separating needle 105 retracts, the needle tip 1051 is completely retracted into the needle hole and does not protrude out of the needle hole.
[0061] For example, taking the first direction Z as the vertical direction, the adjustment method of the preload adjustment member 109 will be described: When the preload adjustment member 109 is adjusted upwards in a direction away from the second mounting base 110, the height of the needle tip 1051 relative to the first mounting base 101 decreases when the separating needle 105 retracts. Conversely, when the preload adjustment member 109 is adjusted downwards in a direction closer to the second mounting base 110, the height of the needle tip 1051 relative to the first mounting base 101 increases when the separating needle 105 retracts. In this way, the present application can adjust the preload adjustment member 109 according to the actual situation so that the needle tip 1051 does not protrude from the needle hole 1141 when the separating needle 105 retracts.
[0062] For example, the elastic element 111 is a spring, which is coaxially arranged with the driving element 1032. The preload adjustment element 109 is a preload adjustment block, a preload adjustment sleeve, or a preload adjustment plate.
[0063] Furthermore, please refer to the following: Figure 5 and Figure 6 The separation mechanism 100 further includes a third stop 112, which is disposed on the pre-pressure adjusting member 109 and can abut or separate from the driving member 1032. When the third stop 112 abuts against the driving member 1032, the pre-pressure adjusting member 109 and the driving member 1032 are fixedly connected. When the third stop 112 separates from the driving member 1032, the pre-pressure adjusting member 109 and the driving member 1032 are in clearance fit. This application realizes the installation and disassembly of the pre-pressure adjusting member 109 and the driving member 1032 through the third stop 112, which has the advantage of convenient operation.
[0064] In some embodiments, please refer to Figures 7 to 9 The separation mechanism 100 also includes an adjustment seat 113 and a separation base 114.
[0065] Adjustment seat 113 is disposed on first mounting seat 101. Separation base 114 is disposed on adjustment seat 113, along the first direction Z, separation base 114 is disposed opposite to first mounting seat 101, pin hole 1141 is disposed on separation base 114, and needle tip 1051 of separation needle 105 is retractably disposed in pin hole 1141.
[0066] The adjusting seat 113 can be adjusted relative to the first mounting seat 101 along the second direction X, and the separating base 114 can be adjusted relative to the adjusting seat 113 along the third direction Y, so that the pinhole 1141 can be adjusted upwards along the second direction X and the third direction Y. The first direction Z, the second direction X, and the third direction Y intersect each other. In this way, the pinhole 1141 can be adjusted to a position aligned with the separating needle 105.
[0067] In certain application scenarios of this application, the first direction Z is the up-down direction, the second direction X is the front-back direction, and the third direction Y is the left-right direction. In other words, the adjusting base 113 can be adjusted to move back and forth, and the separating base 114 can be adjusted to move left and right, so that the pinhole 1141 can be adjusted to move back and forth and left and right.
[0068] Furthermore, referring to Figure 8 The separation mechanism 100 also includes a guide 115 disposed on the separation base 114. The guide 115 has a guide hole 1151. The guide hole 1151 and the pin hole 1141 are disposed opposite to each other along the first direction Z. The separation pin 105 passes through the guide hole 1151 so that the separation pin 105 is guided to the pin hole 1141 to prevent the separation pin 105 from being bent.
[0069] The separation needle 105 can be initially guided to its relative position with the separation base 114 by the guide member 115, which can prevent the separation needle 105 from being forcibly bent. For example, the guide member 115 is a guide plate, guide block or guide plate.
[0070] Furthermore, referring to Figure 9 The separation mechanism 100 also includes a positioning element 116. Both the positioning element 116 and the adjusting seat 113 can be detachably installed on the first mounting seat 101. Along the second direction X, the positioning element 116 abuts against one side of the adjusting seat 113 to position the adjusting seat 113.
[0071] Once the relative position of the adjusting seat 113 is determined, the operator can install the positioning element 116 on the first mounting seat 101 so that the positioning element 116 abuts against one side of the adjusting seat 113. When the adjusting seat 113 is disassembled or replaced and then reinstalled, the positioning element 116 can serve as a positioning reference. The reinstalled adjusting seat 113 can be installed back to its previous position by abutting against the positioning element 116, without the need to reposition the adjusting seat 113 again, which helps to improve the utilization rate of the tape feeding equipment.
[0072] More specifically, the positioning element 116 and the adjusting seat 113 can be detachably installed on the first mounting seat 101 by means of screwing, snap-fitting, magnetic attraction, etc.
[0073] In some embodiments, referencing the back Figure 7 The separation mechanism 100 also includes a ball bushing 117, which is disposed on the first mounting base 101. The needle assembly 102 is clearance-fitted with the ball bushing 117 so that the needle assembly 102 is movably disposed on the first mounting base 101. The ball bushing 117 can reduce the displacement resistance of the needle sheath, making the movement of the needle sheath smoother, thereby making the extension and retraction of the separation needle 105 smoother, which is beneficial to improving the separation efficiency of the separation mechanism 100.
[0074] More specifically, the fit between the ball bushing 117 and the first mounting base 101 can be an interference fit.
[0075] Furthermore, referring to Figure 9 The separation base 114 is also provided with a vacuum adsorption port 1142, and the separation base 114 is also provided with a feeding ramp 1143 between the vacuum adsorption port 1142 and the pinhole 1141.
[0076] When a product is broken or snapped by the separating needle 105, the resulting fragments and debris can slide down the feeding ramp 1143 to the vacuum adsorption port 1142. The vacuum adsorption port 1142 opens to suck away the fragments and debris to avoid affecting the subsequent product separation.
[0077] More specifically, the vacuum adsorption port 1142 does not need to be kept open. For example, it can be opened by sensing whether the product is broken or snapped by an optical fiber. When the product is broken or snapped, the vacuum adsorption port 1142 is opened in a controlled manner.
[0078] Refer to the return Figure 1 The working process of the separation mechanism in this application is described below.
[0079] Debugging process: The operator can adjust the position of the linkage 106 relative to the drive 1032 along the first direction Z according to the actual situation, so that when the separating needle 105 is pushed out, the needle tip 1051 protrudes from the needle hole on the separating base 114. In addition, the operator can also adjust the position of the pre-pressure adjustment component relative to the drive 1032 along the first direction Z, so that when the separating needle 105 retracts, the needle tip 1051 retracts into the needle hole on the separating base 114.
[0080] Separation process: When the power source 1031 is powered on, the drive member 1032 retracts along the direction close to the elastic member 111, compressing the elastic member 111, and drives the needle assembly 102 and the separation needle 105 to retract together via the linkage member 106. When the power source 1031 is de-energized, the elastic member 111 returns to its original position, thereby lifting the drive rod, and the drive member 1032 drives the needle assembly 102 and the separation needle 105 to extend together via the linkage member 106. In this way, the separation needle 105 achieves reciprocating motion of extension and retraction, and the needle tip 1051 protrudes from the needle hole on the separation base 114, which can block continuously fed products, thereby achieving product separation.
[0081] Replacement process: Refer to Figure 2 The operator can loosen the locking screw on the locking member 104 to switch the locking member 104 to the unlocked state. At this time, the needle assembly 102 and the separating needle 105 are in clearance engagement, allowing the separating needle 105 to be pulled out of the needle assembly 102. After the new separating needle 105 is inserted into the needle assembly 102, the locking screw is screwed into the locking member 104 to switch the locking member 104 to the locked state. The locking member 104 then holds the needle assembly 102 tightly, causing the needle assembly 102 to hold the separating needle 105 tightly.
[0082] This application also discloses a tape and reel device, including the separation mechanism described in any of the above embodiments. Specifically, the separation mechanism is connected to the direct vibration module of the tape and reel device to separate the products continuously fed by the direct vibration module into individual products. The products in this application are, for example, surface mount components.
