Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a product calibration mechanism. Background Technology

[0002] In electronic product manufacturing, tape and reel packaging is the mainstream method for protecting, transporting, and automating the placement of chips (usually rectangular). A typical tape and reel machine consists of a placement device, a vibratory feeder, a feeding device, a dispensing device, a tape and reel packaging device, and a take-up device working in concert. The process is as follows: after being sorted by the vibratory feeder, the chips are transferred to the feeding device, which then places them on the dispensing device. Finally, the tape and reel packaging device completes the packaging, and the take-up device collects the chips.

[0003] However, chips are prone to angular misalignment and misalignment during the vibratory feeding and transfer process. Direct packaging would prevent accurate picking in subsequent mounting processes, severely impacting production efficiency. Current technologies typically introduce a correction mechanism after the feeding stage. These mechanisms often employ optical systems incorporating industrial cameras and image processing algorithms for visual positioning and correction. While this approach offers high accuracy, its complex system structure, involving sophisticated optical and computational components, results in high manufacturing costs, hindering widespread industrial adoption and promotion.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

The cam is disposed on the output shaft of the drive motor, and the drive motor is disposed on the side of the support frame opposite to the guide mounting seat. The guide mounting seat has a positioning through hole for accommodating the cam, and the elastic element is connected to the positioning jaws. The drive motor drives the cam to rotate, and the rotating cam abuts against and pushes the positioning gripper, so that the top of each positioning gripper moves radially inward synchronously; the cam separates from the positioning gripper, and the top of the positioning gripper moves radially outward under the action of the elastic element, so as to achieve product correction.

[0007] In the above structure, the positioning gripper includes a positioning block and a correction block. The correction block is disposed at the top of the positioning block. The positioning assembly also includes a bearing. The bearing is connected to the end of the positioning block away from the correction block.

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0020] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0021] Reference Figures 1 to 3 This utility model provides a product calibration mechanism that can be applied to a tape and reel machine for positioning and calibrating product 5. The product 5 calibration mechanism includes a support frame 1, a drive assembly 3, and a positioning assembly 2. The support frame 1 is the base of the entire mechanism and is used to install and support the various components. The positioning assembly 2 includes a guide mounting seat 21, positioning claws 22, and an elastic element. The guide mounting seat 21 is disposed on one side of the support frame 1. Multiple positioning claws 22 are rotatably disposed on the guide mounting seat 21 to clamp product 5. The elastic element is connected to the positioning claws 22 to drive the positioning claws 22 to reset. The drive assembly 3 includes a drive motor 31 and a cam 32. The drive motor 31 is disposed on the side of the support frame 1 facing away from the guide mounting seat 21. The cam 32 is disposed on the output shaft of the drive motor 31 to drive the cam 32 to rotate. The rotation of the cam 32 pushes the positioning claws 22 to open and close. The guide mounting base 21 has a positioning through hole 211 for accommodating the cam 32. The drive motor 31 drives the cam 32 to rotate within the positioning through hole 211. During the rotation of the cam 32, it abuts against and pushes the positioning jaws 22, causing the tips of the multiple positioning jaws 22 to move radially inward synchronously. The elastic element contracts elastically, and the positioning jaws 22 tighten, clamping the product 5. When the cam 32 separates from the positioning jaws 22, the elastic element releases its elasticity, and the tips of the positioning jaws 22 move radially outward under the action of the elastic element. At this time, the positioning jaws 22 open, releasing the product 5. The product 5 is corrected through the repeated tightening and loosening of the positioning jaws 22.

[0022] Reference Figure 2 and Figure 3 Furthermore, the positioning gripper 22 includes a positioning block 221 and a correction block 222. The correction block 222 is in direct contact with the product 5, clamping and correcting the product 5. The positioning block 221 serves as a support for the positioning gripper 22 and is rotatably connected to the guide mounting seat 21, enabling the positioning gripper 22 to open and close. The correction block 222 is located at the top of the positioning block 221, and the connection between the correction block 222 and the positioning block 221 can be secured using common fasteners, such as bolts.

[0023] The positioning assembly 2 also includes a bearing 24, which is connected to the end of the positioning block 221 away from the correction block 222. The cam 32 has multiple protrusions 321 corresponding to the multiple positioning jaws 22, and the bearing 24 can abut against these protrusions 321. During the rotation of the cam 32, the protrusions 321 abut against the bearing 24, pushing the bearing 24 to move radially outward. The positioning block 221 then deflects, causing the correction block 222 to move radially inward. As the cam 32 rotates, the bearing 24, in conjunction with the elastic element, drives the positioning jaws 22 to perform repeated clamping and opening / closing movements, thereby achieving the correction of product 5. Using the cam 32 to drive the opening and closing of the positioning jaws 22 results in a simple structure that is easy to adjust, offers high precision, and saves costs. By setting the bearing 24 to cooperate with the cam 32 to drive the positioning jaws 22, the driving of the positioning jaws 22 becomes smoother and more efficient, which is beneficial for the correction operation. In this embodiment, the bearing 24 is fixed to the positioning block 221 by bolts.

[0024] Furthermore, preferably, the number of positioning grippers 22 is the same as the number of sides of the product 5 to be corrected. In this embodiment, four positioning grippers 22 are provided. The guide mounting base 21 has four limiting openings 212 corresponding to the positioning grippers 22, and the limiting openings 212 are connected to the positioning through holes 211. Correspondingly, the cam 32 is provided with four protrusions 321. A rotating shaft 213 passing through the limiting openings 212 is connected to the guide mounting base 21. The positioning grippers 22 are rotatably mounted on the rotating shaft 213. Specifically, the positioning block 221 is rotatably connected to the rotating shaft 213. The positioning block 221 rotates around the rotating shaft 213 as the fulcrum, thereby realizing the rotation of the positioning grippers 22. The limiting openings 212 guide and limit the swing of the positioning grippers 22 to avoid the positioning grippers 22 from shaking during the swing process and affecting the correction operation of the product 5. In other embodiments, the number of positioning grippers 22 can also be set to three, five, etc., depending on the needs of the product 5, and is not limited here.

[0025] Reference Figure 2 and Figure 3 Furthermore, the positioning component 2 also includes a limiting seat 25, which is detachably fixed to the top of the guide mounting base 21. The limiting seat 25 is used to gather the positioning grippers 22. The limiting seat 25 has limiting grooves 251 that correspond one-to-one with the positioning grippers 22. The limiting grooves 251 are connected to the limiting openings 212. The positioning block 221 moves within the limiting grooves 251, and an elastic element is disposed between the positioning block 221 and the limiting grooves 251. By setting the limiting grooves 251, the movement of the positioning grippers 22 is further limited to ensure the accuracy of the positioning grippers 22's reset action. Moreover, the limiting seat 25 is located above the guide mounting base 21, that is, above the positioning grippers 22, which helps to ensure the stability of the positioning grippers 22's reset and reduces the possibility of shaking during the reset process.

[0026] Furthermore, a limiting bolt 23 is connected to the positioning block 221, which is used to adjust the opening and closing degree of the positioning gripper 22. A positioning groove 252 is provided at the bottom of the limiting groove 251. The limiting bolt 23 is connected and fixed to the positioning block 221 by a nut. The opening and closing degree of the positioning gripper 22 is controlled by controlling the length of the limiting bolt 23 extending between the positioning block 221 and the positioning groove 252.

[0027] An elastic element is used to drive the positioning gripper 22 to reset. Specifically, the elastic element is a reset spring (not shown in the figure). The reset spring is sleeved on the limiting bolt 23, and one end of the reset spring is connected to the limiting seat 25, and the other end is connected to the positioning block 221. In this embodiment, the end of the reset spring connected to the limiting seat 25 is located in the positioning groove 252. When the drive motor 31 drives the cam 32 to rotate, and the cam 32 abuts against and pushes the positioning gripper 22 to swing and clamp the product 5, the reset spring is elastically compressed; when the cam 32 separates from the positioning gripper 22, the reset spring is elastically released, driving the positioning gripper 22 to reset and releasing the product 5.

[0028] Reference Figure 2 Furthermore, the support frame 1 includes a support plate 11 and a support base 12. The support base 12 has an installation groove, the support plate 11 is disposed on the installation groove, and a fixing block 111 is fixedly connected to the support plate 11. An adjusting bolt 13 is connected to the fixing block 111. The adjusting bolt 13 is connected and fixed to the fixing block 111 by a nut. The end of the adjusting bolt 13 is threaded to the support base 12. The distance between the fixing block 111 and the support base 12 can be adjusted by rotating the adjusting bolt 13, thereby adjusting the height of the support plate 11 in the vertical direction, and thus realizing the position adjustment of the positioning gripper 22 in the vertical direction.

[0029] Reference Figure 1 and Figure 2 Furthermore, the bottom of the support frame 1 is also provided with an XY axis displacement stage 4, which is used to drive the support frame 1 to move horizontally, so as to fine adjust the position of the positioning gripper 22 in the horizontal direction.

[0030] Furthermore, a sensing plate 34 is provided on the drive motor 31. The sensing plate 34 is coaxially arranged with the output shaft of the drive motor 31, that is, one end of the output shaft is connected to the cam 32 and the other end is connected to the sensing plate 34. The rotation of the output shaft can drive the sensing plate 34 to rotate synchronously. A photoelectric switch 33 is fixedly provided on the support frame 1. The edge of the sensing plate 34 extends into the sensing groove of the photoelectric switch 33 to form a non-contact photoelectric induction connection. The operation of the drive motor 31 is controlled by the photoelectric switch 33, which effectively improves the response speed and accuracy of the product 5 correction mechanism.
