Description

Technical Field

[0001] This invention belongs to the field of sensor manufacturing equipment, and particularly relates to a PIN pin mounting mechanism and PIN pin mounting equipment. Background Technology

[0002] Pins are required during the manufacturing process of many electronic components. For example, some pressure sensors require four pins on each side. Currently, pins are manufactured as pin strips for easier assembly. Pin structures are diverse, and for pins with grooves on the upper side [e.g.] Figure 1 and Figure 2 As shown, its structure is as follows: the PIN strip is stamped and formed. Its specific structure consists of the lower ends of multiple PIN pins connected to the stamped blank strip 32 (integrated molding), thus forming a strip shape. This type of PIN strip can be customized. During assembly, it needs to be pre-clamped at the corresponding position of the electronic component and cut from the PIN strip. At this time, the PIN pins on the electronic component are pre-installed and can be fixed by soldering later. However, the equipment for PIN pin assembly varies depending on the shape of the PIN pin. Currently, there is no equipment for assembling PIN pins with clamps on the upper side. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a PIN mounting mechanism with a simple structure that can simultaneously mount multiple PIN pins on both sides of an electronic component.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A PIN mounting mechanism includes a base plate, a bracket, two cutting components, and two driving components. The base plate is horizontally arranged, and the bracket is a straight strip that is vertically mounted on the upper middle part of the base plate in the front-back direction. The upper end of the bracket is used to hold electronic components. The cutting components are slidably mounted on the base plate and located on the left and right sides of the bracket. There is a gap channel between each cutting component and the bracket for the PIN strip to pass through. The two driving components correspond one-to-one with the two cutting components and are both mounted on the base plate. The driving end of each driving component is connected to the corresponding cutting component. The driving component is used to drive the corresponding cutting component to move closer to the bracket to engage the PIN pins on the PIN strip with the corresponding side of the electronic component and cut off the PIN pins engaged with the electronic component from the PIN strip. Alternatively, the driving component is used to drive the corresponding cutting component to move away from the bracket to reset.

[0005] The advantages of the above technical solution are: its structure is simple, the driving component drives the corresponding pressing and cutting component to move to squeeze the PIN pins on the corresponding PIN pin strip to the corresponding side of the electronic component, and at the same time the pressing and cutting component cuts off the lower end of the PIN pins that are stuck on the electronic component from the connection of the blank strip, thereby realizing the pre-installation of PIN pins on both sides of the electronic component. It has a high degree of automation and high installation efficiency.

[0006] In the above technical solution, the upper end of the bracket is provided with a groove, which constitutes a placement station for holding the electronic component, and when the electronic component is placed in the placement station, its two sides protrude from the two sides of the bracket.

[0007] The beneficial effect of the above technical solution is that the groove can be used to position and limit the electronic components, avoiding misalignment of the electronic components and causing errors in the pin engagement points.

[0008] The pressure cutting assembly described in the above technical solution includes a clamping block and a slider. Both the clamping block and the slider are slidably mounted on the base plate, and the two clamping blocks are respectively located on the left and right sides of the bracket. The gap between the clamping block and the bracket forms the gap channel. The two sliders are respectively located on the side of the two clamping blocks that are far apart from each other. Each clamping block has a through hole that extends from left to right, and the through hole is located below the placement station. The slider has a cutter protruding from the side of the corresponding clamping block, which passes through the through hole, and the cutting edge of the cutter faces the bracket. The driving assembly has two driving ends. One driving end is connected to the corresponding clamping block, and the other driving end is connected to the corresponding slider. The two driving ends of the driving assembly are used to drive the clamping block and the slider to move left and right, respectively.

[0009] The beneficial effect of the above technical solution is that the PIN clamping and cutting processes are carried out separately. The clamping block first moves to squeeze the PIN pin onto the electronic component and clamps the PIN pin together with the bracket. Then, the slider moves and drives the cutting edge of its cutter to extend through the through hole to cut the lower end of the PIN pin from the blank strip. Finally, the slider and clamping block move in reverse order to reset.

[0010] The driving component in the above technical solution includes a first telescopic driving component and a second telescopic driving component. The first telescopic driving component and the second telescopic driving component are both mounted on the base plate (11) and are both located on the side of the corresponding slider away from the bracket. The telescopic end of the first telescopic driving component faces the corresponding clamp and is connected to the corresponding clamp in a transmission manner. The telescopic end of the second telescopic driving component faces the corresponding slider and is connected to the corresponding slider in a transmission manner.

[0011] The beneficial effects of the above technical solution are: its structure is simple, wherein the first telescopic drive component and the second telescopic drive component operate independently, thereby enabling the clamping block and the slider to slide independently to the left and right.

[0012] In the above technical solution, both the first telescopic drive component and the second telescopic drive component are telescopic cylinders.

[0013] The advantages of the above technical solution are that it has a simple structure and is easy to control.

[0014] The second objective of this invention is to provide a PIN pin installation device with a simple structure and a high degree of automation.

[0015] To achieve the above objectives, the technical solution of the present invention is as follows: A PIN pin mounting device includes two raw material trays, two traction mechanisms, and a PIN pin mounting mechanism as described above. Two convex shafts are provided at the upper end of the base plate behind the PIN pin mounting mechanism. A raw material tray is coaxially and rotatably mounted on each convex shaft. The two raw material trays correspond one-to-one with the two gap channels. A PIN pin strip is wound around the raw material tray. The two traction mechanisms are respectively located in front of the PIN pin mounting mechanism, and each traction mechanism corresponds one-to-one with the two raw material trays. The unwound end of the PIN pin strip on each raw material tray passes through the corresponding gap channel and then through the corresponding traction mechanism. The traction mechanism is used to pull the PIN pin strip from back to front.

[0016] The advantages of the above technical solution are: it has a high degree of automation and realizes automatic feeding of PIN needle tape and automatic discharge of waste material of blank tape, thereby realizing assembly line production.

[0017] The traction mechanism described in the above technical solution includes a guide plate, a clamping roller, and a driving component. The guide plate is horizontally arranged and rotatably mounted on the base plate, and is located in front of the corresponding gap channel. The clamping roller is vertically arranged, and its lower end is rotatably connected to the base plate. The roller wall of the clamping roller is in contact with the edge of the corresponding guide plate. The PIN needle strip passes through the contact area between the corresponding guide plate and the clamping roller. The driving component is mounted on the base plate, and its driving end is connected to the guide plate or the clamping roller. The driving component drives the guide plate and the clamping roller to rotate in opposite directions and drives the PIN needle strip to be conveyed from back to front.

[0018] The advantages of the above technical solution are that it has a simple structure and good traction effect.

[0019] In the above technical solution, the edge of the guide plate is provided with an annular groove that cooperates with the PIN needle strip, and a flexible layer is provided on the roller surface of the clamping roller. The PIN needle strip passes around the annular groove and is pressed and limited in the annular groove by the flexible layer.

[0020] The advantages of the above technical solution are that it provides a good traction effect and keeps the height of the PIN needle band relatively constant.

[0021] The above technical solution also includes a pick-and-place component. The base plate has a raw material station for placing a tray in front of it. The tray contains electronic components. The pick-and-place component is installed on the base plate and is used to pick up and place the electronic components in the tray onto the placement station of the bracket.

[0022] The beneficial effect of the above technical solution is that it further improves the degree of automation.

[0023] The above technical solution also includes a slide groove, which is installed above the base plate, with its discharge end tilted downward and extending out of the base plate. The pick-and-place component is also used to pick up and place the electronic component with PIN pins clamped at the placement station on the bracket into the slide groove, and then slide out of the slide groove.

[0024] The advantages of the above technical solution are that it has a simple structure and allows electronic components pre-loaded with PIN pins to be conveniently delivered through the slide slot. Attached Figure Description

Detailed Implementation

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0037] Example 1

[0038] like Figure 3As shown, this embodiment provides a PIN pin mounting mechanism, including a base plate 11, a bracket 12, two crimping assemblies 13, and two drive assemblies 14. The base plate 11 is horizontally arranged. The bracket 12 is a straight strip and is vertically mounted on the upper center of the base plate 11 in the front-back direction. The upper end of the bracket 12 is used to support electronic components 2. The crimping assemblies 13 are slidably mounted on the base plate 11 and located on the left and right sides of the bracket 12. There is a gap channel between each crimping assembly 13 and the bracket 12 for the PIN pin strip 3 to pass through. The two drive assemblies 14 correspond one-to-one with the two crimping assemblies 13 and are both mounted on the base plate 11. The drive end of each drive assembly 14 is connected to the corresponding crimping assembly 13. The drive assembly 14 is used to drive the PIN pin strip 2. The pressure-cutting assembly 13 moves close to the bracket 12 to engage the PIN pins on the PIN pin strip 3 with the corresponding side of the electronic component 2, and cuts off the PIN pins engaged with the electronic component 2 from the PIN pin strip 3. Alternatively, the driving assembly 14 drives the corresponding pressure-cutting assembly 13 to move away from the bracket 12 to reset. Its structure is simple. The driving assembly drives the corresponding pressure-cutting assembly to move to squeeze the PIN pins on the corresponding PIN pin strip (the PIN pins located on the front side of the corresponding side of the electronic component) to engage with the corresponding side of the electronic component. At the same time, the pressure-cutting assembly cuts off the lower end of the PIN pins engaged with the electronic component at the connection point with the blank strip, thereby realizing the pre-installation of PIN pins on both sides of the electronic component. It has a high degree of automation and high installation efficiency.

[0039] like Figure 4 and Figure 5 As shown, the bracket 12 in the above technical solution has a groove 121 at its upper end. The groove 121 forms a support station for supporting the electronic component 2. When the electronic component 2 is supported at the support station, its two sides protrude from the two sides of the bracket 12. In this way, the groove can position and limit the electronic component, avoiding misalignment of the electronic component and causing errors in the PIN pin engagement point.

[0040] In the above technical solution, the pressure-cutting assembly 13 includes a clamping block 131 and a slider 132. Both the clamping block 131 and the slider 132 are slidably mounted on the base plate 11. The two clamping blocks 131 are located on the left and right sides of the bracket 12, respectively. The gap between the clamping block 131 and the bracket 12 forms the gap channel. The two sliders 132 are located on the sides of the two clamping blocks 131 that are far apart from each other. Each clamping block 131 has a through hole 1311 extending from left to right, and the through hole 1311 is located below the placement station. A cutter 1321 protrudes from the side of the slider 132 closest to the corresponding clamping block 131 and passes through the through hole 1311, with the blade of the cutter 1321 facing upwards. The drive assembly 14 has two drive ends, one of which is connected to the corresponding clamping block 131 and the other is connected to the corresponding slider 132. The two drive ends of the drive assembly 14 are used to drive the clamping block 131 and the slider 132 to move left and right, so that the PIN clamping and cutting processes are performed separately. The clamping block first moves to squeeze the PIN to be clamped onto the electronic component, and the clamping block and the bracket together clamp the PIN. Then the slider moves and drives the cutting edge of its cutter to extend through the through hole to cut the lower end of the PIN from the blank strip. Then the slider and the clamping block move in reverse order to reset.

[0041] Specifically, the driving component 14 in the above technical solution includes a first telescopic driving member 141 and a second telescopic driving member 142. Both the first telescopic driving member 141 and the second telescopic driving member 142 are mounted on the base plate 11 and are located on the side of the corresponding slider 132 away from the bracket 12. The telescopic end of the first telescopic driving member 141 faces the corresponding clamping block 131 and is connected to the corresponding clamping block 131 in a transmission manner. The telescopic end of the second telescopic driving member 142 faces the corresponding slider 132 and is connected to the corresponding slider 132 in a transmission manner. Its structure is simple. The first telescopic driving member and the second telescopic driving member operate independently, so that the clamping block and the slider slide independently to the left and right.

[0042] In the above technical solution, the first telescopic drive component 141 and the second telescopic drive component 142 are both telescopic cylinders, which have simple structures and are easy to control.

[0043] Preferably, the lower end of the clamping block extends to the lower end of the base plate (the base plate has a sliding hole for the clamping block to drive), the first telescopic drive member is located at the lower end of the base plate, and its telescopic end is connected to the lower end of the corresponding clamping block.

[0044] Example 2

[0045] like Figures 6-8As shown, this embodiment provides a PIN pin mounting device, including two raw material trays 8, two traction mechanisms 4, and a PIN pin mounting mechanism 1 as described in Embodiment 1. Two convex shafts 111 are provided at the upper end of the base plate 11 behind the PIN pin mounting mechanism 1. A raw material tray 8 is coaxially rotatably mounted on each convex shaft 111. The two raw material trays 8 correspond one-to-one with the two gap channels. A PIN pin strip 3 is wound around the raw material tray 8. The two traction mechanisms 4 are respectively located in front of the PIN pin mounting mechanism, and each traction mechanism 4 corresponds one-to-one with the two raw material trays 8. The unwound end of the PIN pin strip 3 on each raw material tray 8 passes through the corresponding gap channel and then through the corresponding traction mechanism 4. The traction mechanism 4 is used to pull the PIN pin strip 3 from back to front for conveying. It has a high degree of automation and realizes automatic feeding of the PIN pin strip and automatic discharge of waste material from the blank strip, thereby achieving assembly line production.

[0046] like Figure 9 As shown, the traction mechanism 4 in the above technical solution includes a guide plate 41, a clamping roller 42, and a driving component 43. The guide plate 41 is horizontally arranged and rotatably mounted on the base plate 11, and is located in front of the corresponding gap channel. The clamping roller 42 is vertically arranged, and its lower end is rotatably connected to the base plate 11. The roller wall of the clamping roller 42 is in contact with the edge of the corresponding guide plate 41. The PIN needle strip 3 passes through the contact area between the corresponding guide plate 41 and the clamping roller 42. The driving component 43 is mounted on the base plate 11, and its driving end is connected to the guide plate 41 or the clamping roller 42. The driving component 43 drives the guide plate 41 and the clamping roller 42 to rotate in opposite directions and drives the PIN needle strip 3 to be conveyed from back to front. Its structure is simple and has a good traction effect. The driving component can be a servo geared motor.

[0047] In the above technical solution, the guide plate 41 is provided with an annular groove 411 around its edge to cooperate with the PIN needle strip 3. A flexible layer 421 is provided on the roller surface of the clamping roller 42. The PIN needle strip 3 passes around the annular groove 411 and is pressed and limited in the annular groove 411 by the flexible layer 421. This makes its traction effect good and keeps the height of the PIN needle strip relatively constant.

[0048] like Figure 10 As shown, the above technical solution also includes a pick-and-place component 7. The base plate 11 has a raw material station for placing a tray 5 in front of it. The tray 5 contains electronic components 2. The pick-and-place component 7 is installed on the base plate 11. The pick-and-place component 7 is used to pick up and place the electronic components 2 in the tray 5 onto the placement station of the bracket 12, thereby further improving its automation level.

[0049] The picking and placing component 7 includes an electric moving component 71. The driving end of the electric moving component 71 faces downward and is provided with a mounting base 72. Two finger cylinders 73 with downward-facing clamps are installed at intervals along the front-back direction at the lower end of the mounting base 72. The electric moving component 72 is used to drive the mounting base 72 to move so that one of the finger cylinders 73 can transfer the electronic components in the tray to the picking and placing station, or drive the mounting base to move so that the other finger cylinder 73 can deliver the electronic components pre-loaded with PIN pins from the picking and placing station. The electric moving component can be a two-dimensional moving component or a three-dimensional moving component (both of which belong to the prior art).

[0050] The above technical solution also includes a slide groove 6, which is installed above the base plate 11. Its discharge end is inclined downward and extends out of the base plate 11. The pick-and-place member 7 is also used to pick up the electronic component 2 with PIN pins clamped at the placement station on the bracket 12 and place it into the slide groove 6, and slide it out through the slide groove 6. Its structure is simple and makes it easy to send out the electronic component with PIN pins pre-installed through the slide groove.

[0051] Preferably, the electric moving component 71 is an electric two-dimensional moving component (used to drive the mounting base to move in the vertical plane corresponding to the front-back direction). At this time, the tray is placed in front of the bracket, and the sliding groove is set in the left-right direction above the rear of the bracket. At this time, the electric moving component drives the mounting base and two finger cylinders to move back and forth. The finger cylinder located in front is used to transfer the electronic components in the tray to the placement station, while the finger cylinder located in the rear is used to transfer the electronic components pre-loaded with PIN pins in the placement station to the sliding groove. Multiple electronic components are placed at intervals along the front-back direction on the tray.

[0052] Specifically, the two convex shafts are spaced apart in the left-right direction, and the raw material tray on each convex shaft corresponds to the gap channel on the corresponding side. The base plate (11) is also provided with two guide rollers 9, which correspond one-to-one with the two gap channels. Each guide roller 9 is vertically arranged behind the gap channel. The unwinding end of the PIN needle strip on each raw material tray needs to be guided around the corresponding guide roller 9 before entering the gap channel. The guide rollers and the traction mechanism need to ensure that the PIN needle strip always passes through the gap channel in a straight front-back direction.

[0053] The PIN strips delivered from both of the material trays must have the PIN slot openings facing the electronic component, and the height of the slot openings must be consistent with the height of the PIN mounting points on the side of the electronic component.

[0054] The principle of this embodiment is as follows: First, the pick-and-place device takes out one electronic component from the tray and places it on the placement station. Then, the traction mechanism pulls the PIN pin belt to transport four PIN pins from back to front to the gap channel and align them with the electronic component. Then, the PIN pin installation mechanism pre-installs four PIN pins on each side of the electronic component. Next, the pick-and-place device picks up the electronic component with the pre-installed PIN pins on the placement station and puts it into the sliding groove, and repeats the process.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
