Description

Technical Field

[0001] This utility model relates to the field of code reading equipment technology, and in particular to a code reading auxiliary device. Background Technology

[0002] During production testing, camera modules are marked with QR codes, and the QR code information is read by a barcode reader to identify and distinguish the test level of the workpiece. The existing barcode reading method involves manually placing the workpiece into the positioning slot of a fixture below the barcode reader and then reading the code. This fixture only has a single positioning slot, and can only position and read the code for one workpiece at a time. Therefore, each workpiece needs to be picked up and put back for reading, resulting in low reading efficiency. Moreover, repeated contact with the workpiece can easily damage it. In addition, the distance between the upper surface of the workpiece and the barcode reader must meet the reading requirements. Since the position of the fixture relative to the barcode reader is fixed, different fixtures need to be used for positioning workpieces with different heights and dimensions to meet the reading requirements. This results in low versatility and high testing costs. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention provides a code reading auxiliary device that can adjust the distance between the workpiece and the code reader to accommodate code reading of workpieces of different heights and sizes, thereby improving versatility and reading efficiency.

[0004] According to an embodiment of this utility model, a code reading auxiliary device is provided, including a lifting mechanism and a positioning plate. The lifting mechanism includes a base, a support platform, a first crossbar, and two sets of scissor assemblies. The support platform is disposed above the base, and the first crossbar is slidably connected to the support platform. The two sets of scissor assemblies are respectively disposed on opposite sides of the base. Each scissor assembly includes a first rotating rod, a second rotating rod, and a first positioning member. The first rotating rod and the second rotating rod are arranged crosswise and hinged together. One end of the first rotating rod is rotatably connected to the base, and the first positioning member passes through it. At the other end of the first rotating rod, and the first positioning member is threadedly connected to one end of the first crossbar, one end of the second rotating rod is slidably connected to the base, and the other end of the second rotating rod is rotatably connected to the support platform. The first rotating rod and the second rotating rod can fold or unfold and rotate with each other to drive the support platform to move closer to or away from the base. The first positioning member can abut against the side of the first rotating rod away from the support platform to restrict the rotation of the first rotating rod. The positioning plate is placed on the upper surface of the support platform, and the upper surface of the positioning plate has multiple positioning grooves.

[0005] The code reading auxiliary device of this utility model embodiment has at least the following beneficial effects: In use, the workpiece is placed in the positioning groove of the positioning disk. The first rotating rod and the second rotating rod fold or unfold and rotate with each other, while the first horizontal bar moves horizontally towards or away from the upper end of the second rotating rod, thereby driving the support platform to move towards or away from the base, thereby driving the positioning disk to move up and down. This can adjust the distance between the upper surface of the workpiece and the code reader to meet the code reading requirements. Then, by tightening the first positioning member, the first positioning member abuts against the side of the first rotating rod away from the support platform, thereby restricting the rotation of the first rotating rod and positioning the height position of the support platform. This can adapt to the code reading of workpieces of different heights and sizes, improve versatility, and reduce testing costs. In addition, since the upper end face of the positioning disk has multiple positioning grooves, each positioning groove can install and position one workpiece. By moving the positioning disk horizontally, workpieces at different positions are aligned with the code reader in sequence for code reading, which can improve code reading efficiency and reduce the possibility of workpiece damage due to repeated handling.

The two ends of the first crossbar are slidably connected to the two sliding grooves of the support platform, and one end of the second rotating rod is slidably connected to the sliding groove of the base.

[0009] According to some embodiments of the present invention, the lifting mechanism includes a second crossbar, the two ends of which are slidably connected to the two slide grooves of the base, and one end of the second rotating rod is connected to the second crossbar.

[0027] Understandably, referring to Figures 1 to 4This utility model discloses a code reading auxiliary device, including a lifting mechanism 100 and a positioning plate 200. The lifting mechanism 100 includes a base 110, a support platform 120, a first crossbar 130, and two sets of scissor assemblies 140. The support platform 120 is disposed above the base 110. The first crossbar 130 is slidably connected to the support platform 120. The two sets of scissor assemblies 140 are respectively disposed on opposite sides of the base 110. Each scissor assembly 140 includes a first rotating rod 141, a second rotating rod 142, and a first positioning element 143. The first rotating rod 141 and the second rotating rod 142 are arranged crosswise and hinged together. One end of the first rotating rod 141 is rotatably connected to the base 110. The first positioning element 143... 43 is inserted through the other end of the first rotating rod 141, and the first positioning member 143 is threadedly connected to one end of the first crossbar 130. One end of the second rotating rod 142 is slidably connected to the base 110, and the other end of the second rotating rod 142 is rotatably connected to the support platform 120. The first rotating rod 141 and the second rotating rod 142 can be folded or unfolded and rotated to drive the support platform 120 to move closer to or away from the base 110. The first positioning member 143 can abut against the side of the first rotating rod 141 away from the support platform 120 to restrict the rotation of the first rotating rod 141. The positioning disk 200 is placed on the upper surface of the support platform 120, and the upper surface of the positioning disk 200 is provided with a plurality of positioning grooves 210.

[0028] In use, the workpiece is placed in the positioning groove 210 of the positioning disk 200. The first rotating rod 141 and the second rotating rod 142 fold or unfold and rotate relative to each other, simultaneously causing the first horizontal bar 130 to move horizontally towards or away from the upper end of the second rotating rod 142. This moves the support platform 120 towards or away from the base 110, thereby causing the positioning disk 200 to move up and down. This allows adjustment of the distance from the upper surface of the workpiece to the code reader, adjusting it to meet the code reading requirements. Then, by tightening the first positioning member 143, the first positioning member 143 abuts against... The first rotating rod 141 is positioned away from the support platform 120 to limit its rotation, thereby positioning the height of the support platform 120. This allows for the reading of codes on workpieces of different heights and sizes, improving versatility and reducing testing costs. In addition, since the upper surface of the positioning disk 200 has multiple positioning slots 210, each slot 210 can be used to position a workpiece. By horizontally moving the positioning disk 200, workpieces at different positions can be aligned with the code reader for reading in sequence, which improves reading efficiency and reduces the possibility of workpiece damage due to repeated handling.

[0029] By having the upper ends of the first rotating rods 141 on both sides move synchronously through the first crossbar 130, the synchronicity of the movements of the first rotating rods 141 on both sides can be improved, thereby improving the lifting stability of the support platform 120.

[0030] It should be noted that when the first rotating rod 141 and the second rotating rod 142 fold or unfold and rotate relative to each other, the upper end of the first rotating rod 141 moves toward or away from the upper end of the second rotating rod 142, while the lower end of the second rotating rod 142 moves toward or away from the lower end of the first rotating rod 141. When the first rotating rod 141 moves, it can rotate around its upper end, and when the second rotating rod 142 moves, it can rotate around its lower end.

[0031] When the first positioning member 143 is tightened, it abuts against the side of the first rotating rod 141 opposite to the support platform 120, while simultaneously pressing the first rotating rod 141 against the support platform 120. The rotation of the first rotating rod 141 is restricted by friction and clamping force. To adjust the height of the support platform 120, simply loosen the first positioning member 143, allowing the first rotating rod 141 to rotate.

[0032] The first positioning element 143 can be a hex bolt, which can be easily tightened with a hex wrench. The nut of the hex bolt abuts against the side of the first rotating rod 141 away from the support platform 120 to limit the rotation of the first rotating rod 141, thereby improving the convenience of adjustment.

[0033] Understandably, referring to Figure 1 and Figure 2 Multiple scale lines 121 are provided on the upper surface of the support platform 120 adjacent to the first positioning member 143, and these scale lines 121 are spaced apart along the sliding direction of the first crossbar 130. During adjustment, the sliding of the first crossbar 130 will drive the first positioning member 143 to move. Since the scale lines 121 correspond to the lifting height of the support platform 120, when adjusting the height of the support platform 120, the lifting height of the support platform 120 can be intuitively judged by aligning the first positioning member 143 with the corresponding scale line 121, which can improve the convenience of adjustment.

[0034] Specifically, refer to Figure 1 and Figure 2The first positioning member 143 has a positioning line 144 on its side wall, which is arranged along the axial direction of the first positioning member 143. The positioning line 144 is used to align with the scale line 121. Since the first positioning member 143 has a positioning line 144 on its side wall, which is arranged along the axial direction of the first positioning member 143, during adjustment, the positioning line 144 is positioned at the top of the first positioning member 143 by loosening the first positioning member 143. The lifting height of the support platform 120 is determined by observing the alignment of the positioning line 144 with the corresponding scale line 121. After adjusting to the preset height, the height position of the support platform 120 is positioned by tightening the first positioning member 143. This improves the adjustment accuracy and convenience.

[0035] Understandably, referring to Figure 3 and Figure 4 Both the base 110 and the support platform 120 have two sliding grooves 150 arranged horizontally. The two ends of the first crossbar 130 are slidably connected to the two sliding grooves 150 of the support platform 120, and one end of the second rotating rod 142 is slidably connected to the sliding groove 150 of the base 110. The sliding grooves 150 of the support platform 120 guide the first crossbar 130 to slide horizontally, thereby guiding the upper end of the first rotating rod 141 to move closer to or away from the upper end of the second rotating rod 142. Simultaneously, the sliding grooves 150 of the base 110 guide the lower end of the second rotating rod 142 to move closer to or away from the lower end of the first rotating rod 141, thus improving the stability of the folding or unfolding rotation between the first rotating rod 141 and the second rotating rod 142, and consequently improving the lifting stability of the support platform 120.

[0036] Specifically, refer to Figure 3 and Figure 4 The lifting mechanism 100 includes a second crossbar 160, with both ends of the second crossbar 160 slidably connected to two grooves 150 of the base 110. One end of the second rotating rod 142 is connected to the second crossbar 160. The grooves 150 of the base 110 guide the second crossbar 160 to slide horizontally, thereby guiding the lower end of the second rotating rod 142 to move closer to or further away from the lower end of the first rotating rod 141. This improves the stability of the folding or unfolding rotation between the first rotating rod 141 and the second rotating rod 142, thus enhancing the lifting stability of the support platform 120. Furthermore, the second crossbar 160 drives the lower ends of the second rotating rods 142 on both sides to move synchronously, improving the synchronicity of the movements of the second rotating rods 142 on both sides, thereby enhancing the lifting stability of the support platform 120.

[0037] Specifically, refer to Figure 3 and Figure 4The scissor lift assembly 140 includes a second positioning member 145, which passes through one end of the second rotating rod 142 and is threadedly connected to one end of the second crossbar 160. The second positioning member 145 abuts against the side of the second rotating rod 142 away from the base 110 to restrict the rotation of the second rotating rod 142. When the support platform 120 is adjusted to a preset height position, tightening the second positioning member 145 causes it to abut against the side of the second rotating rod 142 away from the base 110, thus restricting the rotation of the second rotating rod 142 and positioning the height of the support platform 120. Combined with the abutment positioning of the first positioning member 143, this further improves the positional stability of the support platform 120.

[0038] It should be noted that when the second positioning component 145 is tightened, it abuts against the side of the second rotating rod 142 away from the base 110, and the second rotating rod 142 is pressed against the base 110. The rotation of the second rotating rod 142 is restricted by friction and clamping force. When adjusting the height of the support platform 120, the first positioning component 143 and the second positioning component 145 need to be loosened simultaneously, so that the first rotating rod 141 and the second rotating rod 142 can be folded or unfolded and rotated relative to each other.

[0039] It should be noted that the second positioning component 145 can be a hex bolt, which can be easily tightened with a hex wrench. The nut of the hex bolt abuts against the side of the second rotating rod 142 away from the base 110 to limit the rotation of the second rotating rod 142, thereby improving the convenience of adjustment.

[0040] Understandably, referring to Figure 3 The lifting mechanism 100 includes a pivot 170, and the first rotating rod 141 and the second rotating rod 142 on opposite sides are both hinged to the pivot 170. Because the first rotating rod 141 and the second rotating rod 142 on opposite sides are both hinged to the pivot 170, the synchronization of the movements of the first rotating rod 141 and the second rotating rod 142 on both sides can be improved, thereby improving the lifting stability of the support platform 120 and reducing the possibility of swaying of the support platform 120, thus improving the positional stability of the positioning disk 200.

[0041] Understandably, referring to Figure 1 Multiple positioning slots 210 are evenly distributed in a matrix. Because the multiple positioning slots 210 are evenly distributed in a matrix, the workpieces are also evenly placed on the positioning disk 200 in a matrix. By moving the positioning disk 200 horizontally along the longitudinal or transverse direction, the workpieces at different positions can be aligned with the code reader for reading in sequence, which can reduce the possibility of repeated code reading and improve the convenience of code reading.

[0042] Understandably, referring to Figure 1The positioning disk 200 has an opening groove 220 on its side wall. The operator can insert their hand into the opening groove 220 to facilitate the operator's application of force to move the positioning disk 200.

[0043] The positioning disk 200 can be applied to production and testing equipment. The positioning disk 200 is used to load and transfer workpieces. The workpiece can be read by simply transferring the positioning disk 200 to the code reader, which can reduce the damage to the workpiece caused by hand transfer.

[0044] Understandably, referring to Figure 1 The positioning disk 200 has multiple vertically penetrating positioning holes 230. The positioning disk 200 is positioned by inserting positioning pins from the production testing equipment into the positioning holes 230, thereby reducing the movement and shaking of the positioning disk 200 and improving the transport stability of the positioning disk 200.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
