Description

Technical Field

[0001] The utility model relates to a bag measuring machine, in particular to a side guide piece installation structure of the bag measuring machine. Background Art

[0002] A package tester is a device that uses its machinery to test and package electronic components. It is a device that performs the final test on electronic components during the production process to determine whether they can be used.

[0003] Among them, when using the package tester to test the resistance or other types of tests on electronic components, such as Figure 1 As shown, the material enters the gap 103 of the material tray 102 from the feed port 101, and the material tray rotates in a cylindrical chamber 104. A plurality of gaps are set on the outer surface of the material tray, and the outer edge of the material tray is set close to the inner wall of the chamber. Among them, the feed port is composed of the spacing between the upper guide plate and the lower guide plate. After the material enters the gap of the material tray from the feed port, taking the direction shown in the figure as an example, the material tray drives the material to rotate clockwise. After passing the upper guide plate 107, it passes through the cylindrical chamber and then moves to the corresponding detection position for detection. After the detection is completed, it will fall directly from the bottom of one side of the cylindrical chamber. Among them, when the inner surface of the upper guide plate is designed, it is coaxial with the material tray. Two through holes 105 are set on the upper guide plate, and then two bolts pass through the upper guide plate and screw it to the equipment. However, since there will be a certain small distance between the bolts and the through holes and the screw holes on the equipment, the upper guide plate will have the problem of offset. If it is offset toward the material tray, see Figure 2 As shown. After the material enters the notch of the tray, the gap between the upper guide and the tray is too small. When the material is conveyed through the upper guide, the outer end of the material and the product will rub against each other, causing wear or damage to the material. If the upper part is offset away from the tray, there will be a small gap between the connection between the upper guide and the inner wall of the cylindrical chamber, forming a boss 106 between the chamber and the upper guide, see Figure 3 As described above, due to the rotation of the material tray, the material is subjected to a certain centrifugal force, and it will press against the upper guide plate, and then enter the cylindrical chamber and contact the inner surface of the cylindrical chamber. Due to the distance between the two, when the material separates from the upper guide plate and enters the cylindrical chamber, it will collide with the boss 106, causing damage to the material.

[0004] Moreover, it is very difficult to adjust the position of the upper guide piece. Sometimes it deviates to one side and sometimes to the other side (because there is a slight gap between the bolt and the upper guide piece, if the locking force is slightly larger, it may deviate to one side or the other side. If the locking force is insufficient, it is difficult to adjust it). As a result, the product is often scratched or damaged, which seriously affects the product qualification rate and the defective rate is relatively high.

[0005] Since the bag inspection machine is composed of many parts, different workers are usually responsible for different assembly processes during the assembly process. Due to the different assembly techniques of the assemblers, the above-mentioned problems can easily occur. Therefore, how to ensure the installation accuracy of the side guides is a direction that technicians in this field need to work hard on. Summary of the Invention

[0015] The positioning hole is arranged beside the first positioning groove, and two ends of the positioning hole pass through the top surface and the bottom surface of the upper guide piece.

[0016] In the above technical solution, the first positioning groove is a polygonal structure;

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] Example 1: See Figures 4-6 As shown, a side guide installation structure of a package measuring machine includes a base plate component 1, a drive disk 2 installed on the base plate component 1, a side guide and a positioning component 3. The outer surface of the drive disk 2 is circumferentially arranged with a plurality of product positioning grooves 4. The middle part of the positioning component 3 is provided with a chamber 5. The drive disk 2 is rotatably arranged in the chamber 5, and there is a micro gap between the outer edge of the drive disk 2 and the inner wall of the chamber 5. The left side of the positioning component 3 is provided with a notch 6 connected to the chamber 5, and the side guide is installed in the notch 6.

[0038] The side guides include an upper guide 7 and a lower guide 8 spaced apart from each other, with a feed opening 9 formed between the upper guide 7 and the lower guide 8. A slight gap is provided between the outer edge of the drive disc 2 and the inner surfaces of the upper guide 7 and the lower guide 8. The upper end surface of the upper guide 7 abuts against the lower end surface of the notch 6.

[0039] The upper guide piece 7 is provided with a first positioning groove 10 and a positioning hole 11, and the bottom plate component 1 is provided with a first insert 12 matching the first positioning groove 10. The first insert 12 is inserted into the first positioning groove 10.

[0040] A positioning bolt 13 is further provided. The positioning bolt 13 passes through the positioning hole 11 and is connected to the bottom plate component 1 . The positioning bolt 13 limits the upper guide piece 7 to be positioned on the bottom plate component 1 .

[0041] In this embodiment, a detection mechanism facing one of the notches is set above the drive disk or on the positioning component or on the bottom plate component. When in use, the feeding mechanism feeds the material from the feed port into the chamber. Due to the presence of the drive disk, a single material will be fed into a product positioning groove. The width of the product positioning groove will be adapted to the width of a material, or slightly larger than the size of a material. The length of the product positioning groove is slightly smaller than the length of the material. Taking the direction shown in the figure as an example, the drive disk rotates clockwise, which drives the material in the product positioning groove to pass through the inner side of the upper guide plate and then enter the chamber. It is inspected by the detection mechanism, and a drop trough will be set at the lower guide plate or on the base component at the front end. After the material is sent to the drop trough, it falls directly.

[0042] Among them, due to the existence of the gap, the positioning component forms a semicircular ring structure, and the side guide is set in the gap. In theory, the inner surface of the side guide and the inner surface of the chamber form a circular structure. In the previous structure, Figure 2 、 3 As shown, when the upper guide is installed, the package measuring machine has multiple parts. When different parts are assembled, there are different processes. Different processes are performed by different or the same assemblers. Therefore, when different parts are assembled together, the side guides and positioning components may be misaligned due to assembly, debugging, etc., and the drive disk is in a rotating motion, which drives the material to move in an arc-shaped trajectory. The material is affected by the centrifugal force of the arc-shaped trajectory, and the material moves outward away from the drive disk. However, due to the existence of the upper guide, the inner surface of the upper guide will restrict the material, so that most of the material is in the product positioning groove and moves with the rotation of the drive disk (a driving mechanism is set at the bottom of the bottom plate component to drive the drive disk to rotate). If and attached Figure 2 、 3 If there is a slight misalignment in the middle guide blade, the upper guide blade may scratch the material, or when the material passes through the upper guide blade and enters the chamber, there is a misalignment between the notch and the upper guide blade, which is equivalent to forming a boss between the notch and the upper guide blade. When the material passes through the boss, it will be hit by the boss, causing damage to the material. Therefore, in this embodiment, by providing a first positioning groove and a first insert, the side guide blade is positioned using the first insert and the first positioning groove, and then the upper guide blade is fixed using a positioning bolt. Moreover, in the process of locking the upper guide blade and the base component with the positioning bolt, even if the torque of the locking process is large, or other parts are offset in assembly, they will be limited by the first insert and the first positioning groove, so that the upper guide blade will not be offset relative to the bottom plate, thereby being able to accurately fix the upper guide blade to prevent attachment. Figure 2 、 3 It can solve the problems in the production process, prevent the product from being scratched or damaged, and ensure the product's qualification rate and yield rate.

[0043] The bottom plate component includes a bottom plate and a base, the positioning component is installed on the bottom plate, the bottom plate below the notch is a hollow part, and the base is in the hollow part, other components are installed on the base, and the side guide is installed on the base. Some components on the base need to be frequently maintained, so the upper side guide and the lower side guide are detachable structures to facilitate the maintenance of other components on the base. Therefore, the positioning component is not directly set as a ring structure with a feed port, and a side guide needs to be set separately. The side guide can be disassembled to facilitate the maintenance of the components on the base. Therefore, in the utility model, when the upper side guide is installed, due to the presence of the first insert and the first positioning groove, the first insert and the first positioning groove can be used to prevent the installation of the upper side guide and the bottom plate component from being fooled, thereby ensuring that the position of the upper side guide relative to the bottom plate component is accurate.

[0044] The inner surfaces of the upper guide vane and the lower guide vane are coaxially arranged with the drive disk. The drive disk is coaxially arranged with the chamber. The distance between the inner surfaces of the upper guide vane and the lower guide vane and the axis of the drive disk is equal to the radius of the chamber. Therefore, the upper part of the inner surface of the upper guide vane is flush with the inner surface of the chamber above the notch. Therefore, a neat circular surface (with a feed port) is formed between the inner surfaces of the upper guide vane and the lower guide vane and the inner surface of the chamber. In this way, the connection between the inner surface of the upper guide vane and the inner surface of the chamber is continuous and coherent, and there is no misalignment between the two. In addition, the inner surface of the upper guide vane will not be too close to the outer surface of the drive disk, and there will be no problem of friction between the material and the upper guide vane, nor will the material collide with the upper end surface of the notch to prevent the material from being damaged. The connection between the inner surface of the upper guide vane and the inner surface of the chamber forms a relatively smooth arc surface, which can improve the yield and qualified rate of the material.

[0045] See also Figures 4-6 As shown, the first positioning groove 10 is provided in the middle of the upper guide piece 7, and the two ends of the first positioning groove 10 respectively pass through the top surface and the bottom surface of the upper guide piece 7;

[0046] The positioning hole 11 is disposed beside the first positioning groove 10 , and both ends of the positioning hole 11 pass through the top surface and the bottom surface of the upper guide piece 7 .

[0047] The first positioning groove 10 is a polygonal structure.

[0048] Preferably, the first positioning groove is a square or rectangular structure. In this way, the processing of the first positioning groove is convenient. At the same time, the first positioning groove has a polygonal structure, so the first insert also has a polygonal structure. In the process of the positioning bolt passing through the positioning hole to lock the upper guide piece, the transmitted torque can be blocked and limited by the first positioning groove and the first insert with a polygonal structure, so that the upper guide piece will not have a slight offset during the locking process, thereby ensuring the yield and qualification rate of the material.

[0049] A first arc-shaped groove 14 is provided at each corner of the first positioning groove 10 and communicates with the first positioning groove 10 .

[0050] The provision of the first arc-shaped groove facilitates the release of stress at each corner of the first positioning groove to prevent cracking, and also facilitates the assembly of the first insert and the first positioning groove (if the first insert and the first positioning groove are completely fitted together, during assembly, if the gap between the two is too small, the assembly will be difficult. The provision of the first arc-shaped groove can also allow for ventilation during assembly, thereby improving the convenience of assembly. The first arc-shaped groove mainly serves to eliminate stress).

[0051] See also Figure 6 As shown, the upper guide piece 7 is further provided with a second positioning groove 15, and the notch 6 is provided with a second insert 16 extending downward and matching the second positioning groove 15, and the second insert 16 is inserted into the second positioning groove 15. The second positioning groove is provided on the upper end surface of the upper guide piece, and the two ends of the second positioning groove respectively pass through the top surface and the bottom surface of the upper guide piece.

[0052] In this embodiment, since the positioning component is mounted on the base plate component, the two are two independent components, and the upper guide piece, base plate component, and positioning component are three separate components. After the upper guide piece and base plate component are assembled, the first insert and the first positioning groove can be used to prevent the base plate and upper guide piece from being misaligned, thereby ensuring the installation accuracy between the upper guide piece and the base plate component. However, when the positioning component and base plate component are installed, there may be a slight deviation between the positioning component and the upper guide piece, which in turn may lead to a slight deviation between the upper guide piece and the positioning component. Therefore, by providing a second positioning groove and a second insert, a positioning preventive function is implemented between the upper guide piece and the positioning component, thereby ensuring the accurate installation position of the upper guide piece, base plate component, and positioning component. In this way, no matter which operator assembles the upper guide plate, the first insert, the second insert and the corresponding positioning groove can achieve accurate installation and positioning of the upper guide plate, the bottom plate component and the positioning component, and prevent mistakes, prevent the upper guide plate from slightly offset relative to the bottom plate component and the positioning component, ensure assembly accuracy, and thus improve the yield and qualified rate of the material (if the positioning component and the bottom plate component are an integrated structure, the second insert and the second positioning groove can be omitted).

[0053] The second positioning groove is also a polygonal structure, using a square or rectangular structure. A second arc-shaped groove 17 is provided at each of the two corners below the second positioning groove 15 and communicates with the second positioning groove 15. The function of the second arc-shaped groove is the same as that of the first arc-shaped groove, which is mainly to eliminate stress at the corners.

[0054] The bottom plate component is provided with a positioning screw hole facing the positioning hole, and the bottom of the positioning bolt passes through the positioning hole and is screwed to the positioning screw hole. The positioning screw hole is provided on the side of the first insert, facing the positioning hole, for connection with the positioning bolt.

[0055] See also Figure 4 、 5 As shown in Figures 6 and 7, the upper guide piece 7 is arranged above the lower guide piece 8, and the lower guide piece 8 is fixed on the bottom plate member by two bolts. The lower guide piece is arranged at the rear end of the material drop point so that the material does not pass through the lower guide piece. Therefore, even if the lower guide piece deviates, it will not damage the material.

[0056] Wherein, the width of the feed opening formed between the upper guide piece and the lower guide piece is adapted to the width of one of the product positioning grooves.
