Description

Technical Field

[0001] This application relates to the field of planar inspection technology, and in particular to a planar inspection fixture for blister trays. Background Technology

[0002] Thermoforming machines are the core equipment in thermoforming processes. Their technological advantages lie in high-efficiency mass production, flexible customization, and low cost, and they are widely used in packaging and product manufacturing across various industries. When selecting a thermoforming machine, it is necessary to consider production capacity, product requirements, and material characteristics, while also paying attention to the degree of automation, precision, and energy consumption of the equipment to achieve optimal production efficiency and product quality.

[0003] Currently, operators place plastic sheets into a vacuum forming machine, and the vacuum suction generated by a vacuum pump is used to vacuum-form the heated and softened thermoplastic sheet into various shapes of vacuum covers through a mold, or to attach it to the surface of products of various shapes.

[0004] Regarding the aforementioned technologies, the inventors believe that existing blister packaging machines typically rely on visual judgment by operators to inspect the flatness of the blister tray after the blister packaging process. This inspection method is overly dependent on the experience of the inspectors and has the problem of insufficient accuracy in inspecting the flatness of the blister tray. Utility Model Content

[0005] The purpose of this application is to provide a tooling for inspecting the flatness of blister trays, so as to improve the problem of insufficient accuracy in inspecting the flatness of blister trays.

[0006] The blister tray plane inspection fixture provided in this application adopts the following technical solution:

[0007] A blister tray plane inspection fixture includes a base, the base having several supporting members, a slide rail being provided above the supporting members, a slider being slidably mounted on the slide rail, a connecting rod being provided between two slide rails, both ends of the connecting rod being connected to corresponding sliders, and a roller being rotatably mounted on the connecting rod; a positioning plate being provided on the upper surface of the slider, and a differential plate being provided on the roller.

[0008] By adopting the above technical solution, before performing the flatness inspection of the blister tray, the tooling is accurately installed in the template positioning area. By adjusting the height of the support, the connecting rod on the slide rail is kept horizontal with the target inspection plane. The connecting rod is manually pushed to move at a constant speed along the slide rail. When the roller surface contacts the protruding part of the blister tray, it rolls. At this time, the differential plate at the end of the roller and the positioning plate on the slider are displaced and separated. The relative movement of the two directly reflects the height difference between the inspection surface and the reference surface, thus improving the problem of insufficient accuracy in the flatness inspection of the blister tray.

[0009] Optionally, the slider is provided with a positioning groove for the positioning plate to be inserted.

[0010] By adopting the above technical solution, the positioning plate is inserted into the positioning groove after the connecting rod between the sliders is installed, which facilitates the assembly and disassembly of the workpiece.

[0011] Optionally, the positioning plate is provided with a clearance groove for the differential plate to pass through.

[0012] By adopting the above technical solution, before the blister tray is inspected for flatness, the differential plate and the relief groove are kept flush. The relief groove prevents the differential plate from being blocked by the positioning plate when it rotates, thus reducing the impact of the differential plate on the flatness inspection of the roller shaft and the blister tray.

[0013] Optionally, the support member includes a support rod and a support sleeve. One end of the support rod is connected to the slide rail, and the other end is connected to the support sleeve. The other end of the support sleeve, which is connected to the support rod, is connected to the base. The support sleeve is provided with positioning bolts, and the support rod is provided with a plurality of positioning holes that are threadedly connected to the positioning bolts.

[0014] By adopting the above technical solution, the support rod and the support sleeve are fixed by positioning bolts, and the support rod and the support sleeve are rigidly fixed by threaded connection. The multi-position combination of positioning bolts and positioning holes can be selected according to different blister trays, so as to conveniently adjust the support height and adapt to the height requirements of different types of blister trays.

[0015] Optionally, an extension plate is provided at the end of the positioning bolt away from the support rod.

[0016] By adopting the above technical solution, when the positioning bolt is threadedly connected to the positioning hole, the fit between the positioning bolt and the positioning hole can be changed by rotating the extension plate, making it easier to separate the support rod from the support sleeve.

[0017] Optionally, the roller may be provided with an elastic sleeve.

[0018] By adopting the above technical solution, when performing precision testing on the plane of the blister tray, the elastic sleeve on the roller reduces the contact stress between the roller and the blister tray, reduces the deformation of the roller and the blister tray, and protects the testing fixture.

[0019] Optionally, the slide rail is provided with a sliding groove, and the slider is provided with a push rod that passes through the sliding groove.

[0020] By adopting the above technical solution, when the slider and connecting rod are installed on the slide rail, the slider can be easily moved by pushing the push rod on the slider, which reduces the direct contact between the operator and the connecting rod and roller, and improves the impact of manual operation on the detection accuracy.

[0021] Optionally, a handle is provided at the end of the push rod away from the slider.

[0022] By adopting the above technical solution, when pushing the push rod, the operator can increase the contact stress on the push rod by gripping the handle, so that the slider can move more stably on the slide rail.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Before performing the flatness inspection of the blister tray, accurately install the fixture in the template positioning area. By adjusting the height of the support, ensure that the connecting rod on the slide rail is level with the target inspection plane. Manually push the connecting rod to move at a constant speed along the slide rail. When the roller surface contacts the protruding part of the blister tray, it rolls. At this time, the differential plate at the end of the roller and the positioning plate on the slider are displaced and separated. The relative movement of the two directly reflects the height difference between the inspection surface and the reference surface, thus improving the problem of insufficient accuracy in the flatness inspection of the blister tray.

[0025] 2. The support rod and the support sleeve are fixed by positioning bolts, and the support rod and the support sleeve are rigidly fixed by threaded connection. The positioning bolts and positioning holes can be adjusted in multiple combinations according to different blister trays, so as to conveniently adjust the support height and adapt to the height requirements of different types of blister trays.

[0026] 3. When performing precision testing on the surface of the blister tray, the elastic sleeve on the roller reduces the contact stress between the roller and the blister tray, reduces the deformation of the roller and the blister tray, and protects the testing fixture.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail below.

[0031] A tooling for inspecting the flat surface of a blister tray, as shown in the reference. Figure 1The device includes a hollow, horizontal base 1, which facilitates the installation of the testing fixture around the blister tray. Several support members 11 are provided on the upper surface of the base 1 by means of insertion and embedding. The height of the support members 11 is adjusted according to the height of the blister tray plane so that the upper end of the support member 11 is kept horizontal with the blister tray plane. In this embodiment, the number of support members 11 is preferably 4.

[0032] Reference Figure 1 The support member 11 includes a support rod 111 and a support sleeve 112. The support rod 111 is in the shape of a long square rod, and the support sleeve 112 is in the shape of a long square tube. One end of the support rod 111 is connected and fixed to the slide rail 12 by inserting and embedding, and the other end is sleeved inside the support sleeve 112. The other end of the support sleeve 112 connected to the support rod 111 is connected and fixed to the base 1 by inserting and embedding.

[0033] Reference Figure 1 The support sleeve 112 is provided with positioning bolts 113, and the support rod 111 is provided with a number of positioning holes 114 that are threadedly connected to the positioning bolts 113 at equal intervals. In this embodiment, the number of positioning holes 114 is preferably 8. The height of the support member 11 can be changed according to the height of the blister tray by selecting the multi-position combination of positioning bolts 113 and positioning holes 114.

[0034] Reference Figure 1 An extension plate 115 is fixedly installed at the end of the positioning bolt 113 away from the support rod 111 by welding. When installing and removing the positioning bolt 113, the operator can easily change the fit between the positioning bolt 113 and the positioning hole 114 by turning the extension plate 115 without the aid of tools such as torque wrenches.

[0035] Reference Figure 1 and Figure 2 The slide rail 12 is slidably equipped with a slider 13, which is square in shape. A connecting rod 14 is provided between the two slide rails 12. The connecting rod 14 is round in shape and is inserted and fixed to the slider 13. Both ends of the connecting rod 14 are connected to the corresponding slider 13. The connecting rod 14 enables the sliders 13 on the two slide rails 12 to slide synchronously, ensuring that the inspection fixture can perform normal planar inspection on the blister tray.

[0036] Reference Figure 1 and Figure 2The connecting rod 14 is equipped with a roller 15, which is cylindrical. Both ends of the roller 15 are close to the side wall of the slider 13, but not in contact with the side wall of the slider 13. A positioning plate 2 is provided on the upper surface of the slider 13. A differential plate 3 is fixedly provided on the roller 15 by welding. Both the positioning plate 2 and the differential plate 3 are square blocks. When the testing fixture is installed on the blister tray, before performing planar testing on the blister tray, the positioning plate 2 and the differential plate 3 are kept in contact. When the roller 15 contacts the protruding part of the blister tray, the positioning plate 2 and the differential plate 3 separate. The degree of deformation of the deformed part of the blister tray can be judged by the offset distance between the positioning plate 2 and the differential plate 3.

[0037] Reference Figure 1 and Figure 2 An elastic sleeve 151 is fixedly fitted onto the surface of the roller 15. In this embodiment, the elastic sleeve 151 is cylindrical and preferably made of rubber. When the inspection fixture performs planar inspection on the blister tray, the roller 15 contacts the deformed part of the blister tray through the elastic sleeve 151, reducing the irreversible deformation caused when the roller 15 directly contacts the blister tray, protecting the equipment, and ensuring the accuracy of the planar inspection fixture.

[0038] Reference Figure 2 The slide rail 12 is provided with a sliding groove 121, which is elongated and key-shaped. The slider 13 is fixedly provided with a push rod 4 that passes through the sliding groove 121 by means of a threaded connection. The push rod 4 is round and rod-shaped. When performing the flatness inspection of the blister tray, the roller 15 moves along the extension direction of the slide rail 12 by the operator pushing the push rod 4, thereby reducing the influence of the operator on the inspection results during the flatness inspection process.

[0039] Reference Figure 2 A handle 41 is provided at the end of the push rod 4 away from the slider 13. The handle 41 is spherical. When the push rod 4 is pushed, the handle 41 can be used to increase the contact area, reduce the contact stress between the push rod 4 and the slider 13, reduce the offset that occurs when the roller 15 moves along the extension direction of the slide rail 12, and improve the accuracy of plane detection.

[0040] The implementation principle of this application embodiment is as follows:

[0041] After installing the testing fixture on the blister tray, push the push rod 4 to move the roller 15 along the extension direction of the slide rail 12. When there is a deformed part of the blister tray, the deformed part of the blister tray comes into contact with the elastic sleeve 151 on the roller 15, causing the roller 15 to rotate. At this time, the differential plate 3 separates from the positioning plate 2. The degree of deformation of the blister tray can be preliminarily judged based on the rotational displacement of the differential plate 3, thereby improving the problem of insufficient accuracy in detecting the flatness of the blister tray.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
