Description

TECHNICAL FIELD

[0001] The utility model relates to pin machine equipment technical field, concretely relates to a flow channel transmission groove and transmission device for pin machine. BACKGROUND

[0002] Pin machine is an automatic equipment used in electronic manufacturing process, mainly used for inserting electronic components into designated positions on printed circuit board (PCB). Among them, the flow channel groove of pin machine is an important part of its feeding system, which is used to guide and direct the transmission of electronic components. At present, the pin insertion process of PIN pin is mainly guided by the flow channel groove to the two cutting knives of the cutting mechanism for shearing. But because PIN pin is relatively long, it is easy to turn over during transmission, causing PIN pin to be stuck in the flow channel groove, thus causing the feeding to be interrupted.

[0003] Based on this, a pin material groove for conveying pins disclosed in Chinese invention patent document (CN109742636B) sets a pin pushing block above the pin material groove, sets a pin placing seat at the back, arranges a group of pin grooves for placing pins on the pin placing seat, sets a pin pushing rod on one side of the pin placing seat, and the pin pushing rod is connected with a pin pushing rod cylinder. The pin material groove disclosed in the above invention patent document can realize the rapid transportation of pins and avoid the pin sticking phenomenon. However, it designs multiple components and electrical elements, and the structure is relatively complex. In the current pin machine, if the above pin material groove structure needs to be added, many parts need to be changed, and the cost is high. UTILITY MODEL CONTENT

[0004] The utility model provides a flow channel transmission groove and transmission device for pin machine to solve the problems of pin sticking and complex anti-sticking structure in the prior art.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of providing a flow channel transmission groove for pin machine, which comprises a base, a first guide section, a second guide section and a third guide section.

[0006] The base comprises a bottom plate and a mounting plate, wherein the mounting plate is provided with a plurality of positioning pieces spaced apart along a first direction, and the positioning pieces sequentially penetrate the mounting plate and the bottom plate along a second direction; the first guide section comprises a top unobstructed feeding groove along the first direction formed by the combination of the mounting plate and the bottom plate.

[0007] The secondary guiding section comprises a baffle and a transmission flow channel communicated with the feeding slot, wherein the transmission flow channel is formed by the baffle and the mounting plate arranged at intervals along the first direction; the tertiary guiding section comprises a discharging slot communicated with the transmission flow channel and a limiting strip located at the discharging slot, and the discharging slot is protruded along the first direction by the positioning member to form the discharging slot of the tertiary guiding section.

[0008] The technical scheme provided by the utility model has the beneficial effects compared with the prior art:

[0009] The feeding slot formed by the mounting plate is unobstructed, so as to eliminate abnormal accumulation of the PIN pins (such as PIN pin parallel phenomenon), and the transmission flow channel communicated with the feeding slot and the discharging slot respectively is used to limit that only the PIN pins can pass in single column, so that the subsequent chuck can smoothly clamp the PIN pins in the unobstructed discharging slot.

[0010] The transmission flow channel is provided with a baffle to rigidly fix the PIN pins located in the transmission flow channel, so as to correct the posture of the needle body, and the limiting strip and the baffle jointly limit and correct the PIN pins, so as to facilitate the subsequent chuck tool to clamp. In addition, the mounting plate is provided with a plurality of positioning members arranged at intervals along the first direction, and the positioning member can determine the bottom surface (i.e. reference surface) of the flow channel transmission slot by adjusting the mounting height, so that the needle body located in the discharging slot is consistent with the reference height of the external shearing assembly, and then when the PIN needle body is replaced, the shearing process can be adapted by changing the mounting position without replacing the flow channel transmission slot.

[0011] In some embodiments, the primary guiding section is further provided with a feeding channel, and the feeding channel gradually narrows in width along the first direction towards one side of the feeding slot; wherein the base is further provided with a feeding baffle, and the feeding baffle is connected with the bottom plate to form the feeding channel.

[0012] By adopting the above technical scheme, the feeding channel gradually narrows in width along the first direction, and the "funnel effect" is formed in cooperation with the feeding baffle, so that the scattered PIN pins are gradually aligned in single column before entering the feeding slot, and the accumulation caused by disordered collision at the inlet is avoided.

[0013] In some embodiments, the tertiary guiding section is provided with a first notch, and the first notch is located at the mounting plate and located at one side away from the discharging slot along the third direction. Further, the tertiary guiding section further comprises a second notch, and the second notch is arranged at intervals along the first direction with the first notch.

[0014] The first notch can facilitate positioning of the flow channel transmission groove at the outlet end, so as to ensure that the PIN pin body of the discharge groove of the flow channel transmission groove is located at the same reference height as the shearing assembly, thereby facilitating shearing of the PIN pin body. The second notch can further ensure the positioning height of the outlet end of the flow channel transmission groove, thereby improving the positioning accuracy.

[0015] In some embodiments, the length of the discharge groove is greater than the length of the feeding groove. The lengthened discharge groove can increase the clippable length of the PIN pin and provide sufficient operation space for the chuck tool.

[0016] In some embodiments, the mounting plate is further provided with a mounting groove extending in the first direction, and the mounting groove is located between the transmission flow channel and the positioning member in the third direction.

[0017] The mounting groove can provide deformation space for thermal expansion and contraction of the mounting plate and the base, and the mounting groove can also mount an external push rod assembly to facilitate pushing and transmission of the PIN pin in the transmission flow channel.

[0018] In some embodiments, the limiting strip extends to the feeding groove in the first direction. The limiting strip can correct the transmission posture of the PIN pin and limit the PIN pin to prevent it from falling out of the unshielded part of the feeding groove or the discharge groove. Further, the limiting strip is higher than the mounting plate in the second direction to form a physical barrier to prevent the PIN pin from falling out during high-speed transmission.

[0019] In some embodiments, the outer surface of the base and the mounting plate has a hard chromium layer.

[0020] The hard chromium layer deposited on the metal substrate by electroplating process can improve the hardness, wear resistance, corrosion resistance and appearance of the mounting plate and the base, and can improve the overall hardness of the flow channel transmission groove, thereby improving the wear resistance and durability.

[0021] In some embodiments, the positioning member includes a first positioning member, a second positioning member, a third positioning member and a fourth positioning member arranged in sequence in the second direction, and the distance between the second positioning member and the third positioning member is 8-12 mm.

[0022] The smaller spacing of the positioning member in the middle and the larger spacing of the other positioning members ensure that when the transmission flow channel is connected by multiple sheet metal members, the second positioning member and the third positioning member with smaller spacing can ensure that there is no large height difference between the flow channel grooves under high-frequency vibration, thereby avoiding deformation of the flow channel grooves to block the PIN pin.

[0023] In some embodiments, this application also provides a transfer device including one or more of the flow channel transfer grooves and push rod assemblies for a pin insertion machine described above, the push rod assembly being connected to the flow channel transfer groove and used to push a target product located in the feed chute and the flow channel groove.

[0024] By adopting the above technical solution, the head assembly that contacts the shearing component in the existing conventional pin insertion machine's transmission device can be replaced with the aforementioned flow channel transmission groove, thereby reducing the probability of pin jamming and improving the clamping efficiency of the chuck. Furthermore, this structural replacement does not require significant modifications to the existing device, achieving a significant improvement in processing efficiency at a relatively low cost.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0038] In order to facilitate subsequent description, before describing the specific structure of the flow channel transmission slot and the transmission device for the pin inserting machine, the present application first combines Figures 1 to 3 defines the first direction (X), the second direction (Z) and the third direction (Y). Among them, the first direction is the length direction of the flow channel transmission slot for the pin inserting machine when it is normally placed, for example, the X direction; the second direction is the height direction of the flow channel transmission slot for the pin inserting machine when it is normally placed, for example, the Z direction; and the third direction is the width direction of the flow channel transmission slot for the pin inserting machine when it is normally placed, for example, the Y direction. In the present application, the first direction (X), the second direction (Z) and the third direction (Y) are perpendicular to each other.

[0039] It can be understood that the perpendicular to each other in the present application is not absolute perpendicular, and the approximate perpendicular (for example, the included angle between two structural features is 89.9°) caused by processing error and assembly error is also within the range of the perpendicular to each other in the present application.

[0040] Referring to Figure 1 , the present application provides a top view of an embodiment of a flow channel transmission slot; Figure 2 , the present application provides a front view of an embodiment of a flow channel transmission slot; Figure 1 , the present application provides a front view of an embodiment of a flow channel transmission slot; Figure 3 . Figure 2 , the present application provides a front view of an embodiment of a flow channel transmission slot; Figure 1 .

[0041] In some embodiments, the flow channel transmission groove for the pin inserting machine comprises a base 10, a first guide section 20, a second guide section 30 and a third guide section 40. The base 10 comprises a bottom plate 11 and a mounting plate 12, wherein the mounting plate 12 is provided with a plurality of positioning members 13 spaced apart along a first direction, and the positioning members 13 sequentially penetrate the mounting plate 12 and the bottom plate 11 along a second direction; the first guide section 20 comprises a top unobstructed feeding groove 21 along the first direction formed by the combination of the mounting plate 12 and the bottom plate 11.

[0042] The second guide section 30 comprises a baffle 31 and a transmission flow channel 32 communicating with the feeding groove 21, wherein the transmission flow channel 32 is formed by the combination of the baffle and the mounting plate 12 spaced apart along the first direction; the third guide section 40 comprises a discharging groove 41 communicating with the transmission flow channel 32 and a limiting strip 42 located at the discharging groove 41, and the discharging groove 41 is formed by the positioning members 13 protruding along the first direction to form the discharging groove 41 of the third guide section 40.

[0043] In the embodiments of the present application, the unobstructed feeding groove 21 is formed by the mounting plate 12, as shown in FIGS. 1 and 2, and the top of the feeding groove 21 and the discharging groove 41 is free of the baffle 31, so as to exclude the abnormal accumulation of PIN pins (such as PIN pins in parallel) and limit the PIN pins to pass through in single column through the transmission flow channel 32 communicating with the feeding groove 21 and the discharging groove 41 respectively, thereby facilitating the subsequent gripper to smoothly clamp the PIN pins in the unobstructed discharging groove 41. Figure 3 Figure 3 As shown in FIGS. 1 and 2, the top of the feeding groove 21 and the discharging groove 41 is free of the baffle 31, so as to exclude the abnormal accumulation of PIN pins (such as PIN pins in parallel) and limit the PIN pins to pass through in single column through the transmission flow channel 32 communicating with the feeding groove 21 and the discharging groove 41 respectively, thereby facilitating the subsequent gripper to smoothly clamp the PIN pins in the unobstructed discharging groove 41.

[0044] The transmission flow channel 32 is provided with the baffle 31 to rigidly fix the PIN pins located in the transmission flow channel 32 and correct the posture of the PIN pins, and the limiting strip 42 and the baffle 31 jointly limit and correct the PIN pins, thereby facilitating the subsequent gripper tool to clamp. Exemplarily, the limiting strip 42 is a rib protruding from the discharging groove 41 along a third direction of the bottom plate 11, so as to limit the posture of the PIN pins and facilitate the gripper tool to clamp. In addition, the mounting plate 12 is provided with a plurality of positioning members 13 spaced apart along the first direction, and the positioning members 13 can determine the bottom surface of the flow channel transmission groove (i.e., the bottom edge of the mounting plate 12 as a reference surface matched with the subsequent shearing tool) by adjusting the mounting height, for example, the reference surface is the bottom surface of the transmission flow channel 32 aligned with the shearing plane of the shearing tool. Thus, the pin body located in the discharging groove 41 is consistent with the reference height of the external shearing assembly, and when the PIN pin body is replaced, the shearing process can be adapted by changing the mounting position without replacing the flow channel transmission groove.

[0045] In some embodiments, the length of the discharging groove 41 is greater than the length of the feeding groove 21. In the embodiments of the present application, the lengthened discharging groove 41 can improve the clampable length of the PIN pins and provide sufficient operation space for the gripper tool.

[0046] In combination with​Figure 4 and Figure 4 as shown, Figure 1 shows a partial schematic view of an embodiment of a flow channel transmission groove provided by the present application Figure 3 .

[0047] In some embodiments, the combination Figure 4 as shown, the first guide section 20 is further provided with a feeding channel 22, which gradually narrows in width along the first direction towards one side of the feeding groove 21; wherein the base 10 is further provided with a feeding baffle 14, which is connected with the bottom plate 11 to form the feeding channel 22.

[0048] In the embodiment of the present application, the feeding channel 22 gradually narrows in width along the first direction, cooperating with the feeding baffle 14 to form a "funnel effect", which forces the scattered PIN pins to gradually align into a single column before entering the feeding groove 21, avoiding accumulation caused by disordered collision at the entrance. Exemplarily, as shown in Figure 5 as shown, the feeding baffle 14 is connected with the mounting plate 12, which is further inclined inwardly along the edge. Wherein, the inclination height is shown as A, which is 0.3mm in some application scenarios.

[0049] as shown, Figure 5 as shown, Figure 2 shows a partial schematic view of an embodiment of a flow channel transmission groove provided by the present application Figure 3 .

[0050] In some embodiments, the third guide section 40 is provided with a first notch 43, which is located on the mounting plate 12 and located on one side away from the discharging groove 41 along the third direction. Further, the third guide section 40 further includes a second notch 44, which is arranged in steps with the first notch 43 along the first direction.

[0051] In the embodiment of the present application, the first notch 43 can facilitate positioning of the flow channel transmission groove at the outlet end, thereby ensuring that the PIN pin body of the discharging groove 41 of the flow channel transmission groove can be located at the same reference height as the shearing assembly, thereby facilitating shearing of the PIN pin body. Wherein, the second notch 44 can further ensure the positioning height of the outlet end of the flow channel transmission groove, thereby improving the positioning accuracy. Exemplarily, a third notch 45 can be further added to make the step distribution of different specifications, thereby facilitating positioning and installation of the flow channel groove. For example, the length of the third notch 45 is 1mm, the length of the second notch 44 is 5mm, and the length of the first notch 43 is 31mm, which increases layer by layer.

[0052] as shown, Figure 6 and Figure 6 as shown, Figure 6 shows a side view of an embodiment of a flow channel transmission groove provided by the present application.

[0053] In some implementations, the limiting strip 42 (e.g.) Figure 2 (As shown in the shaded area) it extends along the first direction to the feed trough 21. In this embodiment, the limiting strip 42 can correct the transmission posture of the PIN and limit the PIN to prevent it from coming out along the unobstructed part of the feed trough 21 or the discharge trough 41. Further, the stop strip 31 is higher than the mounting plate 12 along the second direction to form a physical barrier to prevent the PIN from coming out during high-speed transmission.

[0054] Combination Figure 3 , Figure 7 and Figure 7 As shown, Figure 7 A side view of an embodiment of a positioning member 13 for a flow channel transfer groove provided in this application is shown.

[0055] In some embodiments, the positioning element 13 includes a first positioning element 130, a second positioning element 131, a third positioning element 132 and a fourth positioning element 133 arranged sequentially along a second direction, wherein the distance between the second positioning element 131 and the third positioning element 132 is 8 mm to 12 mm.

[0056] In this embodiment, the spacing between the central positioning members 13 is small, while the spacing between the other positioning members 13 is large. This ensures that when the transmission channel 32 is connected by multiple sheet metal parts, the smaller spacing between the second and third positioning members 131 and 132 ensures that there is no significant height difference between the channel grooves under high-frequency vibration, thereby preventing channel groove deformation and thus avoiding PIN pin obstruction. For example, in conjunction with... Figure 8 As shown, the positioning component 13 can be a non-standard screw, and the positioning component 13 is embedded in the mounting plate 12 through the undercut process.

[0057] See Figure 8 As shown, ​ A three-dimensional structural schematic diagram of an embodiment of a positioning member 13 for a flow channel transfer groove provided in this application is shown.

[0058] In some embodiments, the mounting plate 12 is further provided with a mounting groove 120 extending along a first direction, the mounting groove 120 being located between the transmission channel 32 and the positioning member 13 along a third direction. In the embodiments of this application, the addition of the mounting groove 120 can provide deformation space for the thermal expansion and contraction of the mounting plate 12 and the base 10, and the mounting groove 120 can also be used to install an external push rod assembly to facilitate the pushing and transmission of the PIN pins located in the transmission channel 32.

[0059] In some implementations, the outer surfaces of the base 10 and the mounting plate 12 have a hard chrome plating.

[0060] In the embodiment of the present application, the hardness, wear resistance, corrosion resistance and appearance of the mounting plate 12 and the bottom plate 11 are improved by depositing a layer of chromium on the metal substrate through the electroplating process, the overall hardness of the flow channel transmission groove is improved, and the wear resistance and durability are improved.

[0061] In some embodiments, the present application also provides a transmission device comprising one or more flow channel transmission grooves and push rod assemblies for the pin inserting machine as described above, the push rod assemblies are connected with the flow channel transmission grooves and used for pushing the target products located in the feeding groove 21 and the flow channel groove.

[0062] In the embodiment of the present application, the head assembly of the transmission device of the existing conventional pin inserting machine in contact with the shearing assembly is replaced by the flow channel transmission groove as described above, so as to reduce the blocking probability of the PIN pin and improve the clamping efficiency of the chuck. The replacement of the structure as described above does not require a substantial change of the existing device, and the processing efficiency can be significantly improved at a lower cost.

[0063] The above is only the embodiment of the present application, and does not limit the patent range of the present application, any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields should be within the protection scope of the present application.
