Description

Technical Field

[0001] The utility model relates to the technical field of components, in particular to a combined bonding tool for heat-conducting components used in a calorimeter. Background Art

[0002] Electronic components are components of electronic elements and small machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in industries such as electrical appliances, radios, and instruments. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and springs. Common ones include diodes.

[0003] In a calorimeter, some thermal conductive components are usually used to measure the corresponding thermal reaction. The thermal conductive components should be accurately positioned on the heat sink assembly to ensure the symmetry of the sample and reference channel during the calorimetric process, reduce the heat loss of the experimental sample reaction in the sample stage, and improve the calorimetric accuracy. However, since the thermal conductive components themselves have high installation accuracy and corresponding adhesives need to be applied between the thermal conductive components and the heat sink assembly, the bonding balance and stability of the thermal conductive components are poor, and it is easy to be skewed due to unevenness during the bonding process.

A compression spring 12 is fixedly mounted on the top of the force measuring device 11, and one end of the compression spring 12 away from the force measuring device 11 is attached to the bottom of the compression butterfly nut 10. Through the rebound lifting spring 9 and the compression spring 12 and the force measuring device 11 on the fixed block 7, the uniformity and consistency of the compression force of the test samples and the reference samples on the two groups of sample tables 5 during the bonding and curing process can be ensured, and the compression force of all identical assemblies can be monitored in real time, ensuring that the bonding process will not damage the heat flux sensor 4 due to excessive pressure. A gluing mechanism 13 for improving the bonding effect is provided on the constant temperature heat sink 1. By setting the gluing mechanism 13, the silver glue can be evenly laid inside the mounting groove 3, ensuring that the silver glue at the bottom of the heat flux sensor 4 is evenly coated during splicing and installation.

[0023] The glue coating mechanism 13 comprises an L-rod 131, a push rod 132, a return spring 133, a connecting rod 134, a hopper 135, a leather roller 136, a limit block 137 and a connecting frame 138; the L-rod 131 is slidably connected to the inner wall of the constant temperature heat sink 1, and the L-rod 131 penetrates the constant temperature heat sink 1, a connecting rod 134 is fixedly installed on the top of the L-rod 131, a hopper 135 is fixedly installed on the end of the connecting rod 134 away from the L-rod 131, and the interior of the hopper 135 is used to store silver glue, the push rod 132 is slidably connected to the inner wall of the connecting rod 134, and the push rod 132 penetrates the connecting rod 134, pushes the L-rod 131, and makes the L-rod 131 collapse toward the interior of the constant temperature heat sink 1, and at the same time, the push rod 132 and the hopper 135 can be driven to move synchronously in cooperation with the connecting rod 134, and at the same time, the leather roller 136 can be driven in cooperation with the connecting frame 138 in the installation groove 3 rolls inside, a limit block 137 is fixedly installed on the top of the push rod 132, a connecting frame 138 is fixedly installed on the bottom of the push rod 132, and a leather roller 136 is rotatably connected to the inner wall of the connecting frame 138, and the outer wall of the leather roller 136 fits the bottom of the hopper 135. The leather roller 136 can be used to seal the bottom of the hopper 135 to prevent the silver glue from flowing downward. When the leather roller 136 is separated from the bottom of the hopper 135 and rolls inside the mounting groove 3, the silver glue will flow to the surface of the leather roller 136 through the hopper 135, so that the leather roller 136 can evenly apply the silver glue to the inside of the mounting groove 3. One end of the reset spring 133 is fixedly installed on the bottom of the limit block 137, and the other end of the reset spring 133 is fixedly installed on the bottom of the connecting rod 134. The limit block 137 and the push rod 132 can be driven to slide upward and reset through the reset spring 133.

[0024] The push rod 132 is provided with a scraper mechanism 14 for smoothing the silver glue. The scraper mechanism 14 can be used to smooth the silver glue applied by the roller 136, so that the heat flow sensor 4 can be in uniform contact with the silver glue. The scraper mechanism 14 includes a screw rod 141, a knob 142, a slide rod 143, and a scraper 144. One end of the screw rod 141 is rotatably connected to the inner wall of the push rod 132, and the other end of the screw rod 141 passes through the limit block 137 and is fixedly installed with the knob 142. The inner wall of the push rod 132 is slidably connected to the slide rod 143. The bottom of the scraper 144 can be adjusted by sliding the slide rod 143. The spacing between the inner walls of the mounting groove 3, a scraper 144 is fixedly installed at one end of the sliding rod 143 away from the push rod 132. When the leather roller 136 applies glue inside the mounting groove 3, the scraper 144 can scrape the silver glue applied by the leather roller 136 flat, so that the heat flux sensor 4 can be in uniform contact with the silver glue, thereby improving the installation stability of the heat flux sensor 4. The inner wall of the sliding rod 143 is threadedly connected to the outer wall of the screw rod 141, and the screw rod 141 is rotatably connected to the penetration point of the limit block 137. The screw rod 141 is rotated by the knob 142 to drive the sliding rod 143 to slide up and down on the side wall of the push rod 132.

[0025] Working principle: first, pour the silver glue into the inside of the hopper 135, then press the limit block 137 downward, compress the reset spring 133 and drive the push rod 132 to move downward, so that the push rod 132 can drive the connecting frame 138 to move downward, so that the connecting frame 138 drives the roller 136 to move downward, so that the roller 136 is separated from the bottom of the hopper 135 and fits inside the installation groove 3. At this time, the silver glue inside the hopper 135 will flow downward to the surface of the roller 136. At this time, push the L rod 131 again, so that the L rod 131 moves to the inside of the constant temperature heat sink 1 The part collapses, and at the same time, the connecting rod 134 can drive the push rod 132 and the hopper 135 to move synchronously. At the same time, the connecting frame 138 can drive the roller 136 to roll inside the mounting groove 3, so that the silver glue flowing from the hopper 135 to the surface of the roller 136 can be evenly smeared on the inside of the mounting groove 3, so that the silver glue is evenly laid on the inside of the mounting groove 3. At this time, the heat flow sensor 4 can be installed in the inside of the mounting groove 3 to ensure that the silver glue at the bottom of the heat flow sensor 4 is evenly smeared during splicing and installation, and will not affect the subsequent bonding balance.

[0026] By rotating the screw rod 141 through the knob 142, the slide rod 143 can be driven to slide up and down on the side wall of the push rod 132. The sliding of the slide rod 143 can adjust the distance between the bottom of the scraper 144 and the inner wall of the installation groove 3. After the adjustment is completed, when the leather roller 136 is applying glue inside the installation groove 3, the scraper 144 can scrape the silver glue applied by the leather roller 136 flat, so that the heat flux sensor 4 can be evenly in contact with the silver glue, thereby improving the installation stability of the heat flux sensor 4.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
