[0003] This utility model relates to the field of photocuring technology, and in particular to a photocuring device. Background Technology
[0004] Photocuring refers to the curing process of monomers, oligomers, or polymer matrices under light induction. Photocuring equipment is typically used to cure the material within an irradiated object. However, how to make photocuring equipment more convenient for curing the material within an irradiated object remains a pressing problem. Utility Model Content
[0005] This invention provides a photocuring device.
[0006] The photocuring apparatus of this application includes a housing, a fixing mechanism, and a light source. The housing forms a receiving cavity and includes a bottom wall. The fixing mechanism is disposed within the receiving cavity and includes a first positioning block connected to the bottom wall. The first positioning block is configured to fix the object to be irradiated. The light source is disposed on the housing and located on at least one side of the fixing mechanism. The light source is used to irradiate the object.
[0007] In the photocuring apparatus of this application embodiment, the first positioning block is connected to the bottom wall, which facilitates fixing the object to be irradiated onto the first positioning block, thereby increasing the ease of installation and stability of the object. Furthermore, the light source is located on at least one side of the fixing mechanism, allowing the light source to irradiate the object from at least one side, which improves irradiation efficiency and thus enhances the curing efficiency of the photocuring apparatus.
[0008] In some embodiments, the housing includes sidewalls, the thickness direction of the irradiated object is configured to pass through the sidewalls, and a light source is disposed on the sidewalls.
[0009] In this way, the light source can irradiate the object from the side, increasing the irradiated area and thus improving the curing efficiency.
[0010] In some embodiments, there are two sidewalls, which are arranged opposite each other, and a fixing mechanism is arranged between the two sidewalls. Both sidewalls are provided with light sources.
[0011] In this way, by irradiating both sides of the object with light sources on the two side walls, the irradiation area can be increased, which is beneficial to improving the curing efficiency.
[0012] In some embodiments, the housing also includes a top wall connected to the side walls, and the top wall is provided with a light source.
[0013] In this way, the light source can illuminate the object from the top, increasing the irradiated area and thus improving the curing efficiency.
[0014] In some embodiments, a first positioning groove is formed on the side of the first positioning block away from the bottom wall, and the object to be irradiated is inserted into the first positioning groove.
[0015] In this way, the object to be irradiated can be easily fixed on the first positioning block through the first positioning groove, and it is easy to pick up and put down.
[0016] In some embodiments, the fixing mechanism includes a support member disposed on the first positioning block, the support member being used to abut against the irradiated object.
[0017] In this way, by having the support member come into contact with the irradiated object, support can be provided to the irradiated object, thereby improving the stability of the irradiated object.
[0018] In some embodiments, the housing includes a top wall opposite the bottom wall, and the fixing mechanism includes a second positioning block connected to the top wall, which cooperates with the first positioning block to clamp the object to be irradiated.
[0019] In this way, the second positioning block, in conjunction with the first positioning block, can improve the clamping stability of the irradiated object.
[0020] In some embodiments, a second positioning groove is formed on the side of the second positioning block opposite to the top wall, and the object to be irradiated is inserted into the second positioning groove.
[0021] In this way, the object to be irradiated can be easily fixed on the second positioning block through the second positioning groove, and it is easy to pick up and put down.
[0022] In some embodiments, the light source includes a circuit board and a plurality of light emitters disposed on the circuit board, the plurality of light emitters being arranged in an array.
[0023] In this way, multiple light emitters are arranged in an array, so that the light emitted by multiple light emitters can be evenly irradiated onto the irradiated object, which is beneficial to improving the curing quality.
[0024] In some embodiments, in the first direction, the center distance between two adjacent light emitters is the same and is L1, and in the second direction, the center distance between two adjacent light emitters is the same and is L2, 1≤L1 / L2≤1.25, and the first direction intersects the second direction.
[0025] The center-to-center distance L1 between two adjacent light emitters in the first direction is the same, and the center-to-center distance L2 between two adjacent light emitters in the second direction is the same, allowing multiple light emitters to be arranged in a rectangular array. When the ratio of L1 to L2 is within the aforementioned range, the irradiation requirements can be met while reducing the number of light emitters.
[0026] In some implementations, 15mm < L1 < 30mm, and / or, 15mm < L2 < 30mm.
[0027] When L1 and L2 are within the above range, the number of light emitters can be reduced while meeting the curing requirements.
[0028] In some implementations, the power of each light emitter is P, where P ≤ 1W.
[0029] When the power of the light-emitting element is within the above range, energy loss can be reduced while meeting the curing requirements.
[0030] In some implementations, the current of each light emitter is I, where I ≤ 200mA.
[0031] When the power of the light-emitting element is within the above range, heat generation can be reduced while meeting the curing requirements.
[0032] In some embodiments, the minimum distance between the light emitter and the irradiated object is L3, where 80mm ≤ L3 ≤ 120mm.
[0033] When the minimum distance L3 between the emitting body and the irradiated object is within the above range, the intensity and uniformity of the light received by the emitting body can be improved.
[0034] In some embodiments, the photocuring apparatus includes a heat sink disposed on the housing for venting air into the housing to regulate the temperature within the housing.
[0035] In this way, the heat generated during the curing process can be dissipated through the heat sink, and the temperature inside the cavity can be regulated to make the temperature inside the cavity stable, which helps to reduce the risk of low curing efficiency caused by excessively high or low temperatures inside the cavity.
[0036] In some embodiments, the photocuring apparatus includes a detection mechanism detachably mounted on a fixing mechanism, the detection mechanism being used to detect the energy of the light irradiated by the light source.
[0037] In this way, by having the testing agency detect the energy of the light irradiated by the light source, the energy of the irradiated light can be stabilized, which helps to reduce the risk of low curing efficiency caused by excessively high or low energy of the irradiated light.
[0038] In some embodiments, the detection mechanism includes a mounting bracket and a detection probe disposed on the mounting bracket, the mounting bracket being detachably mounted on a fixing mechanism.
[0039] In this way, the mounting bracket can be detachably installed on the fixing mechanism, making it easy to assemble and disassemble the mounting bracket, thereby facilitating the adjustment of the detection position of the detection probe.
[0040] In some embodiments, the fixing mechanism is provided with at least one fixing point along the second direction, and the mounting bracket is detachably installed at at least one fixing point of the fixing mechanism.
[0041] Thus, at least one fixed point allows the mounting bracket to be installed at at least one position of the fixed mechanism, facilitating the detection probe to detect the energy of light at at least one position.
[0042] In some embodiments, the mounting bracket includes a first mounting part and a second mounting part, the first mounting part and the second mounting part are connected in a bent shape, the first mounting part is provided with a first mounting point, the second mounting part is provided with a second mounting point, the first mounting part is connected to a fixing mechanism through the first mounting point, and the second mounting part is connected to a detection probe through the second mounting point.
[0043] Thus, the first mounting point facilitates the installation of the first mounting part on the fixed mechanism, and the second mounting point facilitates the installation of the detection probe on the second mounting part.
[0044] In some embodiments, the second mounting part is provided with at least one second mounting point along the first direction and / or the third direction, and the detection probe is detachably mounted on at least one second mounting point of the second mounting part to adjust the position of the detection probe, wherein the first direction, the second direction and the third direction are perpendicular to each other.
[0045] Thus, by means of at least one second mounting point in the first direction and / or the third direction, the position of the detection probe can be easily adjusted in the first direction and the third direction.
[0046] In some embodiments, the fixing mechanism has an end face opposite to the bottom wall, and the second mounting part has a mounting surface for mounting the detection probe, the mounting surface being flush with the end face; or, the first mounting part protrudes from the end face, and along the second direction, the mounting surface is configured to be located between the dimensions of the irradiated object.
[0047] When the mounting surface is flush with the end face, the detection probe is positioned close to the fixing mechanism, which facilitates energy detection of the irradiated light near the fixing mechanism. When the mounting surface is located between the dimensions of the irradiated object, the detection probe is located between the dimensions of the irradiated object, which facilitates energy detection of the light irradiated between the dimensions of the irradiated object. By adjusting the position of the mounting surface, the position of the detection probe can be adjusted, which facilitates energy detection of the irradiated light at different positions.

The housing 10 forms a receiving cavity 11 and includes a bottom wall 12. The fixing mechanism 20 is disposed in the receiving cavity 11 and includes a first positioning block 21 connected to the bottom wall 12. The first positioning block 21 is configured to fix the irradiated object 200. The light source 30 is disposed on the housing 10 and located on at least one side of the fixing mechanism 20.

[0068] The light source 30 can be disposed on one side, two sides, or three sides of the fixing mechanism 20. The light source 30 can emit light of various wavelengths, such as ultraviolet light, infrared light, and visible light. In one embodiment, the light source 30 emits visible light with a wavelength of 450nm.

[0071] In this way, the light source 30 can irradiate the object 200 from the side, increasing the irradiation area and thus improving the curing efficiency.
[0072] Specifically, the sidewall 13 can be connected to the bottom wall 12. The sidewall 13 and the bottom wall 12 can be integrally formed or fixedly connected by welding or other methods. The thickness direction of the irradiated object 200 can be consistent with the thickness direction of the sidewall 13, and the irradiation direction of the light source 30 can be the thickness direction of the irradiated object 200.
[0073] Please see Figure 2 In some embodiments, there are two sidewalls 13, which are arranged opposite to each other. The fixing mechanism 20 is arranged between the two sidewalls 13, and each sidewall 13 is provided with a light source 30.
[0074] In this way, by irradiating both sides of the object 200 with the light source 30 on the two side walls 13, the irradiation area can be increased, which is beneficial to improving the curing efficiency.
[0075] Specifically, the two sidewalls 13 can be arranged opposite each other along the thickness direction of the sidewalls 13, and the light source 30 can be arranged on the side of the sidewall 13 facing the fixing mechanism 20. The position and size of the light source 30 on the two sidewalls 13 can be the same.
[0076] Please see Figure 2 In some embodiments, the housing 10 further includes a top wall 14 connected to the side wall 13, and the top wall 14 is provided with a light source 30.
[0077] In this way, the light source 30 can irradiate the object 200 from the top, increasing the irradiation area and thus improving the curing efficiency.
[0078] Specifically, the top wall 14 and the side wall 13 can be integrally formed or fixedly connected by welding or other methods. The height direction of the irradiated object 200 can be consistent with the thickness direction of the top wall 14. The top wall 14 and the bottom wall 12 are arranged opposite to each other. The light source 30 can be set on the side of the top wall 14 facing the bottom wall 12. The irradiation direction of the light source 30 can be the height direction of the irradiated object 200.

[0080] Thus, the first positioning groove 22 facilitates the fixing of the irradiated object 200 onto the first positioning block 21, and makes it easy to pick up and put down.
[0081] Specifically, the first positioning groove 22 can be formed by removing part of the material from the surface of the first positioning block 21 away from the bottom wall 12 towards the bottom wall 12. The shape and size of the first positioning groove 22 can be determined according to the shape and size of the irradiated object 200.
[0082] Please see Figure 2 In some embodiments, the fixing mechanism 20 includes a support 23 disposed on the first positioning block 21, and the support 23 is used to abut against the irradiated object 200.
[0083] In this way, by abutting against the object 200, the support member 23 can provide support for the object 200 and improve the stability of the object 200.
[0084] Specifically, the support member 23 can be integrally formed with the first positioning block 21, or it can be mechanically connected to the first positioning block 21. There can be multiple support members 23, which are disposed on at least one side of the irradiated object 200 in the length and thickness directions. For example, the support member 23 may be disposed on one side of the irradiated object 200 in the length and thickness directions; or, for another example, the support member 23 may be disposed on both sides of the irradiated object 200 in the length or thickness directions; or, for yet another example, the support member 23 may be disposed on both sides of the irradiated object 200 in the length and thickness directions.
[0085] Please see Figure 2 In some embodiments, the housing 10 includes a top wall 14 opposite to the bottom wall 12, and the fixing mechanism 20 includes a second positioning block 24 connected to the top wall 14. The second positioning block 24 cooperates with the first positioning block 21 to clamp the object 200 to be irradiated.
[0086] Thus, the second positioning block 24 cooperates with the first positioning block 21 to improve the clamping stability of the irradiated object 200.
[0087] Specifically, the top wall 14 can be connected to the side wall 13. The top wall 14 is located above the bottom wall 12. The first positioning block 21 is located on the side of the bottom wall 12 facing the top wall 14, and the second positioning block 24 is located on the side of the top wall 14 facing the bottom wall 12.
[0088] The distance between the first positioning block 21 and the second positioning block 24 can be less than the height of the object being irradiated 200, so that the object to be cured can be located between the first positioning block 21 and the second positioning block 24, which facilitates the light source 30 to cure the object.
[0089] Please see Figure 2 and Figure 3 In some embodiments, a second positioning groove 25 is formed on the side of the second positioning block 24 away from the top wall 14, and the irradiated object 200 is inserted into the second positioning groove 25.
[0090] Thus, the second positioning groove 25 facilitates the fixing of the irradiated object 200 onto the second positioning block 24, and makes it easy to pick up and put down.
[0091] Specifically, the second positioning groove 25 can be formed by removing part of the material from the surface of the second positioning block 24 away from the top wall 14 towards the top wall 14, and the shape and size of the second positioning groove 25 can be determined according to the shape and size of the irradiated object 200.

[0093] In this way, the multiple light emitters 32 are arranged in an array, so that the light emitted by the multiple light emitters 32 can be evenly irradiated onto the irradiated object 200, which is beneficial to improving the curing quality.
[0094] Specifically, the size of the circuit board 31 can be greater than or equal to the size of the object 200 being irradiated, that is, the length of the circuit board 31 can be greater than or equal to the length of the object 200 being irradiated, and the width of the circuit board 31 can be greater than or equal to the width of the object 200 being irradiated, so that the light-emitting body 32 on the circuit board 31 can fully irradiate the object 200 being irradiated.
[0095] The light-emitting element 32 and the circuit board 31 can be connected by soldering. The light-emitting element 32 can be an LED lamp bead, and multiple light-emitting elements 32 can form a rectangular array. For example, the number of light-emitting elements 32 is 10, and the 10 light-emitting elements 32 form a 5×2 array.
[0096] The circuit board 31 can be embedded in the side wall 13 or it can be set on the side of the side wall 13 facing the fixing mechanism 20. The light-emitting body 32 can be set on the side of the circuit board 31 facing the fixing mechanism 20.

[0098] The center distance L1 between two adjacent light emitters 32 in the first direction D1 is the same, and the center distance L2 between two adjacent light emitters 32 in the second direction D2 is the same, so that multiple light emitters 32 can be arranged in a rectangular array. When the ratio of L1 to L2 is within the above range, the irradiation requirements can be met while reducing the number of light emitters 32.
[0099] Specifically, the first direction D1 can be the length direction of the irradiated object 200, and the second direction D2 can be the height direction of the irradiated object 200. The first direction D1 and the second direction D2 are perpendicular. L1 / L2 can be 1, 1.05, 1.1, 1.15, 1.2, 1.25, etc.
[0100] In some implementations, 15mm < L1 < 30mm, and / or, 15mm < L2 < 30mm.
[0101] When L1 and L2 are within the above range, the number of light emitters 32 can be reduced while meeting the curing requirements.
[0102] Specifically, it can be 15mm < L1 < 30mm, or 15mm < L2 < 30mm, or 15mm < L1 < 30mm, and 15mm < L2 < 30mm.
[0103] L1 can be 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, etc., and L2 can be 17mm, 19mm, 21mm, 23mm, 25mm, 27mm, 29mm, etc.
[0104] In some implementations, the power of each light emitter 32 is P, where P ≤ 1W.
[0105] When the power of the light emitter 32 is within the above range, energy loss can be reduced while meeting the curing requirements.
[0106] Specifically, the power of the light-emitting body 32 can be 0.8W, 0.85W, 0.9W, 0.95W, 1W, etc., and the power of multiple light-emitting bodies 32 can be the same or different.
[0107] In some implementations, the current of each light emitter 32 is I, where I ≤ 200mA.
[0108] When the power of the light emitter 32 is within the above range, heat generation can be reduced while meeting the curing requirements.
[0109] Specifically, the current of the light-emitting body 32 can be 150mA, 160mA, 170mA, 180mA, 190mA, 200mA, etc., and the currents of multiple light-emitting bodies 32 can be the same or different.
[0110] In some embodiments, the minimum distance between the light emitter 32 and the irradiated object 200 is L3, where 80mm≤L3≤120mm.
[0111] When the minimum distance L3 between the light emitter 32 and the irradiated object 200 is within the above range, the intensity and uniformity of the light received by the light emitter 32 can be improved.
[0112] Specifically, the minimum distance L3 between the light source 32 and the irradiated object 200 can be the distance between the surfaces of the light source 32 and the irradiated object 200 that are close to each other. L3 can be 80mm, 90mm, 100mm, 110mm, 120mm, etc.
[0113] In one embodiment, the minimum distance L3 between the light emitter 32 and the irradiated object 200 is 100mm, the intensity of the light received at the light emitter 32 is 100W / ㎡, and the uniformity of the light on the receiving surface with an area of 80mm×40mm is 80%.
[0114] Please see Figure 2 In some embodiments, the photocuring apparatus 100 includes a heat sink 40 disposed on the housing 10, which is used to ventilate the housing 11 to regulate the temperature inside the housing 11.
[0115] In this way, the heat generated during the curing process can be dissipated by the heat sink 40, and the temperature inside the cavity 11 can be regulated to stabilize the temperature inside the cavity 11. This helps to reduce the risk of low curing efficiency caused by excessively high or low temperatures inside the cavity 11.
[0116] Specifically, the housing 10 may include a front wall 15 and a rear wall 16, which are arranged opposite each other along a first direction D1. The top wall 14, bottom wall 12, front wall 15, rear wall 16, and two side walls 13 together form a receiving cavity 11. The front wall 15 may be rotatably connected to the side wall 13, the bottom wall 12, or the top wall 14 to form a door. When the door is open, it is convenient to take out and put in the object to be irradiated 200. When the door is closed, it is convenient for the light source 30 to irradiate the object to be irradiated 200.
[0117] The radiator 40 can be installed on the rear wall 16, and the air inlet 17 can be installed on the bottom wall 12. Outside air enters the receiving cavity 11 through the air inlet 17, and the heat generated during the curing process is discharged to the outside through the radiator 40 along with the air in the receiving cavity 11.
[0118] Please see Figure 5 In some embodiments, the photocuring apparatus 100 includes a detection mechanism 50, which is detachably mounted on the fixing mechanism 20 and is used to detect the energy of the light irradiated by the light source 30.
[0119] In this way, by having the testing agency 50 detect the energy of the light irradiated by the light source 30, the energy of the irradiated light is stabilized, which helps to reduce the risk of low curing efficiency caused by excessively high or low energy of the irradiated light.
[0120] Specifically, the energy of the light irradiated by the light source 30 can be detected first using the detection probe 52. After the detection is passed, the irradiated object 200 can be fixed on the fixing mechanism 20 for photocuring.
[0121] Please see Figure 5 and Figure 6 In some embodiments, the detection mechanism 50 includes a mounting bracket 51 and a detection probe 52 disposed on the mounting bracket 51, the mounting bracket 51 being detachably mounted on the fixing mechanism 20.
[0122] Thus, the mounting bracket 51 is detachably mounted on the fixing mechanism 20, making it easy to assemble and disassemble the mounting bracket 51, thereby facilitating the adjustment of the detection position of the detection probe 52.
[0123] Specifically, the mounting bracket 51 can be made of materials such as metal or plastic, and the number of mounting brackets 51 can be one or more.
[0124] The detection probe 52 can be a power sensor. In one embodiment, the detection probe 52 is an S130C series thin photodiode power sensor with a detection power range of 5mW-500mW and a detection wavelength of 400nm-1100nm. The number of detection probes 52 can be one or more.
[0125] Please see Figure 5 and Figure 6 In some embodiments, the fixing mechanism 20 is provided with at least one fixing point 26 along the second direction D2, and the mounting bracket 51 is detachably mounted on at least one fixing point 26 of the fixing mechanism 20.
[0126] Thus, at least one fixed point 26 allows the mounting bracket 51 to be installed at at least one position of the fixing mechanism 20, facilitating the detection probe 52 to perform energy detection on the light at at least one position.
[0127] Specifically, the fixing mechanism 20 may be provided with multiple fixing slots 27, and each fixing point 26 includes at least one fixing slot 27. For example, the first positioning block 21 has two fixing slots 27 on the side facing the front wall 15, and the mounting bracket 51 is fixed to the first positioning block 21 through the two fixing slots 27. The second positioning block 24 has two fixing slots 27 on the side facing the front wall 15, and the mounting bracket 51 is fixed to the second positioning block 24 through the two fixing slots 27.
[0128] Please see Figure 5 and Figure 6 In some embodiments, the mounting bracket 51 includes a first mounting part 53 and a second mounting part 54. The first mounting part 53 and the second mounting part 54 are connected in a bent shape. The first mounting part 53 is provided with a first mounting point 55, and the second mounting part 54 is provided with a second mounting point 56. The first mounting part 53 is connected to the fixing mechanism 20 through the first mounting point 55, and the second mounting part 54 is connected to the detection probe 52 through the second mounting point 56.
[0129] Thus, the first mounting point 55 facilitates the mounting of the first mounting part 53 on the fixing mechanism 20, and the second mounting point 56 facilitates the mounting of the detection probe 52 on the second mounting part 54.
[0130] Specifically, the first mounting portion 53 and the second mounting portion 54 can be sheet-like structures, and the first mounting portion 53 and the second mounting portion 54 can form an L-shape. The first mounting portion 53 can be provided with a plurality of first through holes 57, and the first mounting point 55 includes at least one first through hole 57; the second mounting portion 54 can be provided with a plurality of second through holes 58, and the second mounting point 56 includes at least one second through hole 58.
[0131] For example, the first mounting part 53 is provided with two first through holes 57, which correspond to two fixing slots 27 on the first positioning block 21 or the second positioning block 24; the second mounting part 54 is provided with two second through holes 58; and the detection probe 52 is provided with two mounting holes 521, which correspond to the two mounting holes 521 on the detection probe 52.
[0132] Please see Figure 6 In some embodiments, the second mounting part 54 is provided with at least one second mounting point 56 along the first direction D1 and / or the third direction D3, and the detection probe 52 is detachably mounted on at least one second mounting point 56 of the second mounting part 54 to adjust the position of the detection probe 52, wherein the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.
[0133] Thus, the position of the detection probe 52 can be adjusted in the first direction D1 and the third direction D3 by at least one second mounting point 56.
[0134] Specifically, the third direction D3 can be the thickness direction of the irradiated object 200, and the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The second mounting part 54 may have at least one second mounting point 56 along the first direction D1, or the second mounting part 54 may have at least one second mounting point 56 along the third direction D3, or the second mounting part 54 may have at least one second mounting point 56 along both the first direction D1 and the third direction D3.
[0135] For example, the second mounting part 54 is provided with four second mounting points 56, which form a 2×2 matrix along the first direction D1 and the third direction D3. A single detection probe 52 may be mounted on one of the second mounting points 56, or two detection probes 52 may be simultaneously mounted on two second mounting points 56 spaced apart along the third direction D3, or both detection probes 52 may be simultaneously mounted on second mounting points 56 spaced apart along the first direction D1 and the third direction D3.
[0136] Please see Figure 5 and Figure 7 In some embodiments, the fixing mechanism 20 has an end face 28 opposite to the bottom wall 12, and the second mounting part 54 has a mounting surface 59 for mounting the detection probe 52, the mounting surface 59 being flush with the end face 28; or, the first mounting part 53 protrudes from the end face 28 along the second direction D2, and the mounting surface 59 is configured to be located between the dimensions of the irradiated object 200.
[0137] When the mounting surface 59 is flush with the end face 28, the detection probe 52 is positioned close to the fixing mechanism 20, which facilitates energy detection of the irradiated light close to the fixing mechanism 20. When the mounting surface 59 is located between the dimensions of the irradiated object 200, the detection probe 52 is located between the dimensions of the irradiated object 200, which facilitates energy detection of the light irradiated between the dimensions of the irradiated object 200. By adjusting the position of the mounting surface 59, the position of the detection probe 52 can be adjusted, which facilitates energy detection of the irradiated light at different positions.
[0138] Specifically, end face 28 can be the surface of the first positioning block 21 facing away from the bottom wall 12, or the surface of the second positioning block 24 facing away from the top wall 14. Mounting surface 59 can be the surface of the second mounting part 54 facing away from the first mounting part 53.
[0139] The mounting surface 59 can be flush with the end face 28 of the first positioning block 21 away from the bottom wall 12, or flush with the end face 28 of the second positioning block 24 away from the top wall 14, or located between the end face 28 of the first positioning block 21 away from the bottom wall 12 and the end face 28 of the second positioning block 24 away from the top wall 14.
