[0003] Existing thickness detectors have some defects during use. When it is necessary to pick up the workpiece that has been inspected, the operator's arm needs to reach deep into the inspection chamber, which is not only laborious but also easy to collide with the inner wall of the chamber or the inspection components, causing damage to the equipment or secondary damage to the workpiece. At the same time, when the workpiece is initially placed and clamped, the inspection chamber is located inside the thickness detector, so the operator's viewing angle is limited, and it is difficult for the operator to accurately and quickly place the workpiece in the ideal clamping position, which greatly reduces production efficiency and increases the difficulty and error rate of manual operation.

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Example 1:

[0040] like Figures 1 to 10 As shown, an SPI solder paste thickness detection machine for producing automobile taillight modules includes a detection unit 100, a feeding unit 200, a clamping unit 300 and a product to be inspected 400.

[0041] The detection unit 100 includes a thickness detector body 101, which is provided with a detection chamber 1013. A sealed door 102 adapted to the detection chamber 1013 is installed at the entrance of the detection chamber 1013 through a hinge. A pair of guide plates 103 are installed on the inner wall of the detection chamber 1013. A pair of guide sliders 1033 are slidably provided on each pair of guide plates 103. A synchronization plate 1034 is installed between the pair of guide sliders 1033. A fixed plate 1035 is installed at the bottom of the synchronization plate 1034. The fixed plate 1035 and the surface of the sealing door 102 are rotatably installed with a rocker arm 1036, and the rocker arm 1036 is in an inclined state; during the rotation of the sealing door 102, the sealing door 102 drives the fixed plate 1035 to move through the rocker arm 1036, and the fixed plate 1035 can drive the two guide sliders 1033 to slide through the synchronization plate 1034, and then push the connected feeding unit 200 and clamping unit 300 to slide. At this time, the inspected product 400 can be sent into the detection chamber 1013.

[0042] The feeding unit 200 includes two sets of swing arms 201, which are rotatably connected to the corresponding guide sliders 1033, and the products 400 to be inspected are overlapped on the two sets of swing arms 201. A rocker 202 is installed on the rotation center of the two sets of swing arms 201. A connecting rod 2031 is vertically slidably provided on the rocker 202. A supporting plate 204 is installed at the bottom of the connecting rod 2031. A pressure plate 205 is installed on the supporting plate 204. The bottom of the pressure plate 205 is installed at the bottom of the detection chamber 1013. The guide rail 2052 is slidably connected, and a slope 2053 is provided on the guide rail 2052; when the pressure plate slides on the guide rail 2052, the pressure plate 205 moves downward as a whole through the guiding effect of the slope 2053, and the pressure plate 205 drives the supporting plate 204 to have a downward movement trend. At this time, the connecting rod 2031 slides downward, and finally drives the rocker plate 202 and the swing arm 201 to rotate, thereby achieving the purpose of flipping and lifting the product 400 for inspection, making it convenient to take the product 400 for inspection.

[0043] The clamping unit 300 includes two pairs of L-shaped brackets 301, each pair of L-shaped brackets 301 is connected to the corresponding fixed plate 1035, a limiting slider 302 is slidably installed on the L-shaped bracket 301, and a force storage cover 304 is rotatably installed on the limiting slider 302. A force storage rod 3041 is inserted inside the force storage cover 304, and a force storage spring 3043 is installed between the force storage rod 3041 and the force storage cover 304. A clamping block 305 is rotatably installed at the end of the force storage rod 3041, and the clamping block 305 is horizontally slidably connected to the fixed block 3052 fixedly installed on the top of the L-shaped bracket 301. The force storage cover 304 is in an inclined state, and an insertion rod 3022 is installed on the side wall of the limiting slider 302. The insertion rod 3022 movably passes through the fixed plate 1035, and a sliding rod 3023 is installed at the end of the insertion rod 3022. The sliding rod 3023 is slidably set in the detection cavity In the combination groove 303 opened at the bottom of 1013, the combination groove 303 includes a feed groove 3031 and a clamping groove 3032. The feed groove 3031 and the clamping groove 3032 are connected to each other. The feed groove 3031 is a linear operation, and the clamping groove 3032 is an inclined groove. When the slide bar 3023 slides from the feed groove 3031 to the clamping groove 3032, the slide bar 3023 drives the insertion rod 3022 to move, and the insertion rod 3022 drives the limit slider 302 to slide toward the side of the L-shaped bracket 301. When the connection point between the limit slider 302 and the force storage cover 304 moves to the other side of the connection point between the force storage rod 3041 and the clamping block 305, the force storage spring 3043 can push the force storage rod 3041 to slide, and the force storage rod 3041 will drive the clamping block 305 connected to the end to slide, thereby achieving the purpose of clamping.

[0044] like Figures 1 to 10 As shown, in a specific embodiment, four support legs 1011 are installed at the bottom corners of the thickness detector body 101. The support legs 1011 improve stability. Anti-slip pads 1012 are installed at the bottom of each of the four support legs 1011. A rotating shaft 1022 is rotatably installed on the side wall of the thickness detector body 101. A locking plate 1021 is installed on the rotating shaft 1022. A handle 1023 is installed on the upper surface of the sealing door 102. An anti-slip sleeve is sleeved on the handle 1023. An observation window 1024 is embedded in the sealing door 102. The handle 1023 can drive the sealing door 102 to rotate around the rotation center, so that the sealing door 102 completely blocks the entrance of the detection chamber 1013. When the sealing is completed, the operator rotates the locking plate 1021 so that the locking plate 1021 covers the sealing door 102, locking the sealing door 102 as a whole. The observation window 1024 facilitates observation of the internal situation.

[0045] like Figures 1 to 10As shown, further, columns 1031 are mounted at both ends of the guide plate 103. The bottoms of the columns 1031 are welded to the bottom of the detection chamber 1013. A guide slot 1032 is formed on the guide plate 103. A guide slider 1033 is mounted on the guide slot 1032. A stopper 104 is mounted on the guide plate 103. The stopper 104 positions the product 400 to be inspected when it moves into the detection chamber 1013.

[0046] Example 2:

[0047] The difference between Example 1 and this example is that: Figures 1 to 10 As shown, a synchronization shaft 2011 is mounted at the bottom of the swing arm 201. Both ends of the synchronization shaft 2011 are rotatably connected to corresponding guide sliders 1033. A clamping plate 2012 is mounted on the synchronization shaft 2011, and a torsion spring 2013 is sleeved on the side wall of the synchronization shaft 2011. One end of the torsion spring 2013 is clamped to the side wall of the clamping plate 2012, and the other end is clamped to the side wall of the guide slider 1033. The synchronization shaft 2011 is connected to the rotation center of the rocker 202. The rocker 202 has a strip groove 2021 formed on it. A protrusion 203 is slidably provided on the strip groove 2021. The protrusion 203 is connected to the side wall of the connecting rod 2031. When the supporting plate 204 and the pressure plate 205 move downward, the protrusion 203 connected to the connecting rod 2031 slides downward synchronously. At this time, the protrusion 203 can rotate on the rocker 202 with a strip groove 2021, and the rocker 202 synchronously drives the synchronization shaft 2011 to rotate. Finally, the synchronization shaft 2011 can drive the guide slider 1033 to rotate, and the torsion spring 2013 connected to the surface is twisted synchronously. The torsion spring 2013 facilitates the later reset operation. When the synchronization shaft 2011 rotates, the synchronization shaft 2011 drives the swing arm 201 to rotate toward the inside of the detection chamber 1013, so that the inspected product 400 can enter the detection chamber 1013.

[0048] like Figures 1 to 10As shown, in a specific embodiment, the sidewall of the support plate 204 is provided with a mounting ear 2041. A positioning rod 2042 is movably installed inside the mounting ear 2041. The top of the positioning rod 2042 is connected to the bottom of the guide slider 1033. A positioning plate 2044 is installed at the bottom of the positioning rod 2042. A positioning spring 2043 is sleeved on the positioning rod 2042. The positioning spring 2043 is respectively engaged with the sidewall of the guide slider 1033 and the sidewall of the mounting ear 2041. A guide wheel 2051 is rotatably installed at the bottom of the pressure plate 205. The guide wheel 2051 is in rolling connection with the guide rail 2052. A blocking block 2054 is installed at the end of the guide rail 2052. The blocking block 2054 has a blocking effect and is higher than the height of the guide rail 2052. In addition, the positioning spring 2043 on the positioning rod 2042 is in a compressed state, and the positioning spring 2043 at this time pushes the mounting ear 2041 and the supporting plate 204 to always have a downward movement trend, ensuring that the guide wheel 2051 on the pressure plate 205 is always in contact with the guide rail 2052.

[0049] Example 3:

[0050] The difference between Example 2 and this example is that: Figures 1 to 10 As shown, a guide rod 3011 is installed inside the L-shaped bracket 301, and fixed seats 3012 are installed at both ends of the guide rod 3011. The L-shaped bracket 301 can slide on the guide rod 3011, ultimately achieving the purpose of guidance, and the fixed seat 3012 is welded to the side wall of the detection cavity 1013. A limiting slide rail 3021 is installed on the L-shaped bracket 301, and the limiting slide rail 3021 is slidably connected to the limiting slider 302, and the limiting slide rail 3021 limits the movement of the limiting slider 302.

[0051] like Figures 1 to 10 As shown, in a specific embodiment, a force storage plate 3042 is slidingly provided inside the force storage cover 304, one end of the force storage plate 3042 is connected to the force storage rod 3041, and a force storage spring 3043 is installed between the other end of the force storage plate 3042 and the force storage cover 304, and the compression direction of the force storage spring 3043 and the moving direction of the force storage rod 3041 are both on the same straight line.

[0052] like Figures 1 to 10As shown, further, a limiting sleeve 3053 is installed on the side wall of the fixed block 3052, and a limiting plate 3054 is movably inserted into the limiting sleeve 3053. A limiting rod 3055 is installed on the limiting plate 3054. The limiting rod 3055 movably passes through the fixed block 3052, and the end of the limiting rod 3055 is connected to the side wall of the clamping block 305. The clamping block 305 is also installed with a clamping plate 3051. When the clamping block 305 slides, the clamping block 305 pulls the limiting rod 3055 to slide on the fixed block 3052, and the limiting plate 3054 at the end of the limiting rod 3055 slides on the limiting sleeve 3053, which serves as a guide to ensure that the clamping block 305 can only slide horizontally.

[0053] The implementation principle of the SPI solder paste thickness detector for producing automobile taillight modules of the present invention is as follows: the operator first places the product 400 coated with solder paste on the upper surface of the swing arm 201, and finally forms Figure 2 The operator then closes the sealing door 102 and rotates the sealing door 102 around the rotation center using the handle 1023, so that the sealing door 102 completely blocks the entrance to the detection chamber 1013. When the sealing is completed, the operator rotates the locking plate 1021 so that the locking plate 1021 covers the sealing door 102, thereby locking the sealing door 102 as a whole.

[0054] During the rotation of the sealing door 102, the sealing door 102 drives the fixed plate 1035 to move through the rocker arm 1036. The fixed plate 1035 can drive the two guide sliders 1033 to slide along the guide groove 1032 through the synchronization plate 1034, thereby pushing the connected feeding unit 200 and clamping unit 300 to slide.

[0055] When the feed unit 200 moves, the pressure plate 205 inside the feed unit 200 can drive the guide wheel 2051 to slide on the guide rail 2052. Under the guidance of the slope 2053, the pressure plate 205 moves downward as a whole, and the pressure plate 205 drives the supporting plate 204 to move downward. In addition, the positioning spring 2043 located on the positioning rod 2042 is in a compressed state. At this time, the positioning spring 2043 pushes the mounting ear 2041 and the supporting plate 204 to always move downward, ensuring that the guide wheel 2051 on the pressure plate 205 is always in contact with the guide rail 2052.

[0056] Therefore, when the supporting plate 204 and the pressing plate 205 move downward, the protrusion 203 connected to the connecting rod 2031 slides downward synchronously, and the protrusion 203 can rotate on the seesaw 202 with the strip groove 2021. The seesaw 202 then drives the synchronous shaft 2011 to rotate, and finally the synchronous shaft 2011 drives the guide slider 1033 to rotate, and the torsion spring 2013 connected to the surface is twisted synchronously. The torsion spring 2013 facilitates the subsequent reset operation. When the synchronous shaft 2011 rotates, the synchronous shaft 2011 drives the swing arm 201 to rotate toward the inside of the detection cavity 1013, allowing the product 400 to enter the detection cavity 1013. In the initial stage, the end of the swing arm 201 is located outside the detection cavity 1013, so it is very convenient to place and take out the product 400 to be inspected at this stage, which makes it easier for the operator to use the thickness detection machine body 101.

[0057] During the sliding of the clamping unit 300, in the initial state of the clamping unit 300, the slide bar 3023 slides along the feed groove 3031 on the combination groove 303, and the clamping unit 300 is not in a clamped and locked state. As the clamping unit 300 continues to move, the slide bar 3023 on the clamping unit 300 will eventually slide into the clamping groove 3032. Through the guiding effect of the clamping groove 3032, the slide bar 3023 slides to both sides at this time, and the slide bar 3023 drives the surface insertion rod 3022 to slide synchronously, and the insertion rod 3022 can drive the end limit slider 302 to slide along the limit slide rail 3021 toward the side of the L-shaped bracket 301.

[0058] When the limit slider 302 slides, the connection point between the limit slider 302 and the force storage cover 304 moves, and during this process, the clamping block 305 at the end of the force storage rod 3041 remains stationary, but the force storage cover 304 slides outside the force storage rod 3041, compressing the force storage spring 3043 on the internal force storage plate 3042. When the connection point between the limit slider 302 and the force storage cover 304 moves to the other side of the connection point between the force storage rod 3041 and the clamping block 305, the force storage spring 3043 can push the force storage rod 3041 to slide, and the force storage rod 3041 will drive the clamping block 305 connected to the end to slide. At this time, the clamping block 305 will drive the clamping plate 3051 to move away from the fixed block 3052. Finally, the clamping plate 3051 can clamp and guide the product 400 to be inspected, facilitating later inspection.

[0059] When the clamping block 305 slides, the clamping block 305 pulls the limiting rod 3055 to slide on the fixed block 3052, and the limiting plate 3054 at the end of the limiting rod 3055 slides on the limiting sleeve 3053, which serves the purpose of guidance and ensures that the clamping block 305 can only slide horizontally.

[0060] After the above operations are completed, the operator starts the thickness detector body 101 to detect the thickness of the SPI solder paste on the inspected product 400. The thickness detector body 101 is a prior art and its working principle will not be described in detail here.
